The rotating mechanism includes a connecting ring fixedly installed on the output end of the lifting mechanism. A first annular cavity with its top end communicating with the outside is opened in the middle of the connecting ring. A rotating ring is rotatably fitted inside the first annular cavity. The upper part of the rotating ring extends out of the first annular cavity and is fixedly installed with a fixed ring. A sealing ring is provided in the gap between the fixed ring and the connecting ring. Support plates are symmetrically fixedly installed on the top of the fixed ring. A waterproof motor II is fixedly installed on one of the support plates. The central-hole fountain light is rotatably installed between the two support plates and is driven by the waterproof motor II.

A fixed ring is fixedly installed in both second annular cavities. A fixed ring is fitted with a conductive ring I, and conductive rings II are fixedly fitted on both the inner and outer sides of the rotating ring. Adjacent conductive rings I and II are in close contact. Conductive ring I is electrically connected to an external power source. The terminals of the central hole fountain light and the waterproof motor II are electrically connected to conductive ring II through the rotating ring. A water level sensor is also fixedly installed on the top of the fixed ring. A drive assembly that drives the fixed ring to rotate circumferentially is provided on one side of the connecting ring. A nozzle is fixedly fitted inside the central hole of the central hole fountain light. A rigid connecting pipe is concentrically fixedly installed within the enclosed area of the connecting ring. Multiple rigid water pipes are provided between the rigid connecting pipe and the nozzle. The nozzle and the rigid water pipe, the rigid connecting pipe and the rigid water pipe, and adjacent rigid water pipes are all connected through universal water pipe joints. A flexible water pipe is fixedly installed at the lower end of the rigid connecting pipe, and the other end of the flexible water pipe is connected to an external water source.
[0006] Preferably, the rigid connecting pipe is externally fixed with a sleeve, and multiple fixing rods are uniformly fixedly installed on the outside of the sleeve along the circumference, with the other end of the fixing rods being fixedly connected to the connecting ring.
[0007] Preferably, the drive assembly includes an external gear ring fixedly fitted on the outer ring surface of the fixed ring, and a waterproof motor I fixedly installed on the outer ring surface of the connecting ring. The output end of the waterproof motor I is fixedly fitted with a gear, which meshes with the external gear ring for transmission.
[0008] Preferably, the lifting mechanism includes a fixed cylinder sealed at both ends and a drive motor fixedly installed inside the fixed cylinder.

[0010] Beneficial Effects: Compared with existing technologies, this utility model provides a liftable fountain light with a unique structure and convenient use. During use, a water level sensor monitors the water level changes in the pool in real time and transmits the signal to the control system. The control system drives the motor according to the water level changes, which in turn drives the screw to rotate via pulleys and a transmission belt, thereby raising and lowering the connecting ring and ensuring the fountain light remains below the water surface. Waterproof motor I drives the fixed ring to rotate horizontally via gears and an external gear ring, thus adjusting the direction of the fountain light. Simultaneously, waterproof motor II is powered by conductive rings I and II, driving the central hole fountain light to rotate. Because the central hole fountain light is integrated with the nozzle and connected via a universal water pipe connector and rigid water pipe, it not only avoids tangling of water pipes and wires but also ensures accurate projection of the fountain water column.
[0011] Through the coordinated operation of a water level sensor, lifting mechanism, and rotating mechanism, this fountain light not only keeps the light below the water surface at all times, but also enables the light to project precisely according to the direction and position of the fountain water column. This avoids light effect deviation and glare problems caused by loose lamps. This design not only improves the visual comfort of the water show, but also enhances the overall viewing effect.

Detailed Implementation
[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0019] Example 1: This Example 1 provides a retractable fountain light, which is a direct improvement on existing fountain lights. It has a unique structure. Please refer to [link / reference]. Figure 1-5 As shown, the device includes a lifting mechanism 1 and a central fountain light 3, as well as a rotating mechanism 2 and a universal water pipe connector 5. The universal water pipe connector 5 is existing equipment, and its working principle and specific structure will not be described in detail. The rotating mechanism 2 includes a connecting ring 21 fixedly installed on the output end of the lifting mechanism 1. The middle of the connecting ring 21 has a first annular cavity with its top end communicating with the outside. A rotating ring 22 is rotatably fitted inside the first annular cavity.

[0020] A second annular cavity is concentrically formed on the connecting rings 21 on both the inner and outer sides of the first annular cavity. A conductive ring I 23 is fixedly fitted into each of the two second annular cavities. A conductive ring II 24 is fixedly fitted onto both the inner and outer sides of the rotating ring 22. Adjacent conductive rings I 23 and II 24 are in close contact. Conductive ring I 23 is electrically connected to an external power source. The terminals of the water level sensor 8, the central hole fountain light 3, and the waterproof motor II 211 are all electrically connected to the conductive ring II 24 through the rotating ring 22. A water level sensor 8 is also fixedly installed on the top of the fixed ring 25. A drive assembly for rotating the fixed ring 25 around its circumference is provided on one side of the connecting ring 21. A spray nozzle is fixedly fitted into the central hole of the central hole fountain light 3. Within the enclosed area of the head 4 and connecting ring 21, a rigid connecting pipe is concentrically fixedly installed; the drive assembly includes an external gear ring 27 fixedly fitted on the outer ring surface of the fixing ring 25, and a waterproof motor I 29 fixedly installed on the outer ring surface of the connecting ring 21. The output end of the waterproof motor I 29 is fixedly fitted with a gear 28, which meshes with the external gear ring 27 for transmission; multiple rigid water pipes 6 are provided between the rigid connecting pipe and the nozzle 4. The nozzle 4 and the rigid water pipes 6, the rigid connecting pipe and the rigid water pipes 6, and two adjacent rigid water pipes 6 are all connected through universal water pipe joints 5. A flexible water pipe 7 is fixedly installed at the lower end of the rigid connecting pipe, and the other end of the flexible water pipe 7 is connected to an external water source.
[0021] The flexible water pipe 7 is connected to the fountain's water pump. The nozzle 4, water level sensor 8, drive motor 17, waterproof motor I 29, and waterproof motor II 211 are all connected to the fountain light's control system and power supply. The universal water pipe connector 5 is an existing connector, and its working principle and specific structure will not be described in detail. There are various ways to connect the rigid connecting pipe. For example, the rigid connecting pipe is externally fixed with a sleeve 212. Multiple fixing rods 213 are evenly fixedly installed on the outside of the sleeve 212 along the circumference. The other end of the fixing rod 213 is fixedly connected to the connecting ring 21.
[0022] The lifting mechanism 1 includes a fixed cylinder 11 sealed at both ends, and a drive motor 17 fixedly installed inside the fixed cylinder 11. The top of the fixed cylinder 11 has two through holes symmetrically opened, which communicate with the inside of the fixed cylinder 11. A screw cylinder 13 is movably fitted inside the through hole. A sealing ring is provided in the gap between the screw cylinder 13 and the through hole. The upper end of the screw cylinder 13 is fixedly connected to the connecting ring 21. A screw rod 14 is threadedly fitted inside each of the two screw cylinders 13. The lower end of the screw rod 14 is rotatably connected to the inner bottom surface of the fixed cylinder 11. A pulley 15 is fixedly fitted on the output shaft of the drive motor 17 and on each of the two screw rods 14. The same transmission belt 16 is fitted on the three pulleys 15. A through hole is vertically opened at the center of the top of the fixed cylinder 11. Two through holes are symmetrically arranged on both sides of the through hole. A sleeve 12 is fixedly fitted inside the through hole. The lower end of the flexible water pipe 7 passes through the sleeve 12 and communicates with the external water source. The length of the flexible water pipe 7 is long enough to facilitate the vertical lifting of the connecting ring 21.
[0023] Working Principle: During use, the water level sensor 8 automatically monitors changes in the water level in the pool. The fountain light's control system can control the lifting mechanism 1 to rise and fall based on the detection signal from the water level sensor 8, ensuring the fountain light remains below the water surface. During lifting, the control system first activates the drive motor 17, which drives two screw cylinders 13 to rotate via belt transmission. The rotating screw cylinders 13 then drive the connecting ring 21 to rise and fall via threaded connections. When the fountain light needs to spray in a specific direction, the waterproof motor I 29 is activated first. The waterproof motor I 29, through meshing transmission, drives the fixed ring 25 horizontally. After rotating to the designated position, the waterproof motor II211 is activated, driving the central hole fountain light 3 to rotate until it reaches the designated position. In addition, since the nozzle 4 is connected to the rigid connecting pipe through the universal water pipe joint 5 and the rigid water pipe 6, and the central hole fountain light 3 and the waterproof motor II211 are connected to the external power supply through the conductive ring I23 and the conductive ring II24, the waterproof motor II211, the central hole fountain light 3, and the nozzle 4 are protected from tangling of water pipes and wires during movement. Furthermore, due to the integrated design of the central hole fountain light 3 and the nozzle 4, the central hole fountain light 3 can accurately project light onto the fountain water column, improving visual appeal and comfort.
[0024] Example 2: The difference between Example 2 and Example 1 is that the bottom of the fixed cylinder 11 is equipped with a wireless water immersion sensor. When water enters the fixed cylinder 11 through the gap between the screw cylinder 13 and the through hole, the wireless water immersion sensor can transmit the signal to the maintenance personnel for maintenance.
[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
