1. A light-emitting (LED) fountain light with a self-cleaning lens, comprising:
a light body with a central hole,
a light housing surrounding the light body,
a nozzle provided in the light housing and located in the central hole,
a central hole pressing ring sleeved in the central hole,
LED light beads arranged between the central hole pressing ring and the light housing and sealed by a sealant,
a driving mechanism provided between the nozzle and the central hole pressing ring,
a cleaning mechanism provided on a surface of the light body to scrape off algae and a dirt, and
a transmission mechanism provided between the driving mechanism and the cleaning mechanism, wherein
the LED light beads are annularly arranged around the central hole; and the self-cleaning lens is annularly provided above an upper surface of each of the LED light beads;
the driving mechanism comprises:
a sleeve fixedly provided between the nozzle and the central hole pressing ring,
a power slider provided in the sleeve and slidable up and down, and
a counterweight provided in the sleeve and cooperating with the power slider; wherein
the sleeve is longitudinally divided into an inner chamber adjacent to the central hole and an outer chamber adjacent to the central hole pressing ring;
the power slider and the counterweight are respectively arranged in the inner chamber and the outer chamber;
the power slider and the counterweight are connected through a flexible rack or toothed chain;
a weight of the power slider is greater than a weight of the counterweight; and
a bottom of the inner chamber is provided with a water inlet hole for injecting a high-pressure water flow;
the central hole pressing ring is provided with a ring cover at a top of the central hole;
the cleaning mechanism comprises:
a plurality of scrapers arranged on the surface of the light body to scrape off the algae and the dirt,
a plurality of scraper supports configured to fix the plurality of scrapers respectively,
a plurality of scraper holders configured to fix the plurality of scraper supports, and
an internal gear ring provided on the ring cover and configured to rotate; wherein
the internal gear ring is coaxial with the central hole pressing ring;
the plurality of scraper holders are uniformly arranged in an array on an upper surface of the internal gear ring; and
the plurality of scrapers is provided along a radial direction of the self-cleaning lens;
the transmission mechanism comprises a gear set and a gear box; wherein
the gear set comprises:
a main gear,
a fixed gear coaxial with the main gear,
a deflection gear,
an end face gear meshed with the fixed gear, and
a translation gear coaxial with the end face gear; wherein
the translation gear meshes with internal teeth of the internal gear ring of the cleaning mechanism;
a gear shaft of the main gear and a gear shaft of the fixed gear are arranged horizontally, and a gear shaft of the end face gear and a gear shaft of the translation gear are arranged vertically;
a gear shaft of the deflection gear is provided horizontally;
the flexible rack or toothed chain meshes with the main gear;
after an end of the flexible rack or toothed chain winds around the main gear and is connected to the counterweight, the end of the flexible rack or toothed chain winds around the deflection gear and then is connected to the counterweight;
the gear shaft of the main gear, the gear shaft of the fixed gear, the gear shaft of the deflection gear, the gear shaft of the end face gear, and the gear shaft of the translation gear are arranged on the gear box; and
the gear set and the gear box are arranged at an upper end of the sleeve;
at a beginning of a fountaining, a water flow enters from the water inlet hole into the inner chamber; under a combined action of the counterweight and an impact of the water flow, the power slider slides from bottom to top in the inner chamber; during sliding of the power slider, the flexible rack or toothed chain drives the main gear to rotate, and the main gear drives the fixed gear to rotate; the fixed gear meshes with the end face gear and drives the end face gear to rotate horizontally; the end face gear drives the translation gear to rotate horizontally; the translation gear drives the internal gear ring to rotate on the ring cover of the central hole pressing ring, thereby driving the plurality of scrapers to clean the algae and the dirt on the surface of the light body; the flexible rack or toothed chain winds around the main gear and is connected to the counterweight through the deflection gear; due to a combined force of a pull force generated by a gravity of the counterweight and an impact force of the water flow on the power slider, the power slider slides along the sleeve from a bottom of the sleeve for a distance equal to a length of the inner chamber; meanwhile, a gear ratio of the fixed gear to the end face gear is adjusted to ensure that the plurality of scrapers scrape at least one circle on the surface of the light body; during the fountaining, the power slider is at the upper end of the sleeve, and the counterweight is at a lower end of the sleeve; at an end of the fountaining, since the weight of the power slider is greater than the weight of the counterweight, the power slider pulls the counterweight upward through the transmission mechanism; the power slider falls to the lower end of the sleeve, and the counterweight is at the upper end of the sleeve; during this process, the transmission mechanism drives the plurality of scrapers to rotate reversely at least one circle, so the surface of the light body is cleaned at the beginning and the end of the fountaining.
