[0045] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of the present invention and, together with the embodiments of the present invention, serve to illustrate the principles of the present invention.

[0046] Example 1

[0047] This embodiment provides a self-cleaning floating platform that can change height according to the water level, such as... Figure 1 and Figure 2 As shown, it includes a display base 1, a display stand 2, a rotating device 3, a cleaning device 4, a floating water tank 5, a positioning column 6, a lifting column 7, a transmission device 8, and an intermittent release device 9.

[0048] The positioning column 6 is fixed in the middle of the display base 1. The outer side of the positioning column 6 contacts the lifting column 7. The top of the lifting column 7 is fixedly connected to the display platform 2. The floating water tank 5 is installed inside the display platform 2. The rotating device 3, the transmission device 8 and the intermittent release device 9 are installed sequentially from top to bottom on the upper part of the lifting column 7. The cleaning device 4 is fixed at the bottom of the intermittent release device 9.

[0049] The display base 1 and the positioning column 6 are both fixed to the bottom of the water such as lakes, rivers, and ponds. The display platform 2 always floats on the water surface through the action of the floating water tank 5. The height of the display platform 2 floating on the water surface can be controlled by adjusting the volume of the gas in the water tank or increasing the counterweight on the display platform 2, so as to accommodate sculptures of different masses placed on the surface of the display platform 2.

[0050] The floating water tank 5 provides buoyancy, allowing the display platform 2 to always float on the water surface. Meanwhile, the positioning column 6 is fixed to the bottom of the lake, river, or pond. The lifting column 7 can only move up and down under the limitation of the positioning column 6. Therefore, the display platform 2 can float with the water level without changing its position.

[0051] The floating water tank 5 has an air injection valve, a water injection port, and a one-way drain valve.

[0052] When it is necessary to raise the height of the display platform 2 relative to the water surface, an air pump is used to add air to the floating tank 5 through the air injection valve to increase the proportion of gas in the floating tank 5, thereby increasing buoyancy and raising the height of the display platform 2 relative to the water surface.

[0053] When it is necessary to lower the height of the display platform 2 relative to the water surface, open the water inlet and insert the end of the air pump pipe into the gas port above the floating tank 5 to extract air. As the gas in the floating tank 5 decreases, water from the lake, river, or pond will flow into the floating tank 5, thereby reducing buoyancy and lowering the height of the display platform 2 relative to the water surface.

[0054] Preferably, the upper part of the lifting column 7 is a regular octagonal column.

[0055] The regular octagonal prism is used to facilitate the fixing of parts to the lifting column 7.

[0056] Preferred, such as Figure 3 As shown, the rotating device 3 includes a first connecting plate 31, a first slewing bearing 32, and a rotating paddle 33. The first connecting plate 31 is fixedly connected to the lifting column 7, and the first connecting plate 31 is fixedly connected to one seat ring of the first slewing bearing 32. The rotating paddle 33 is fixedly connected to the other seat ring of the first slewing bearing 32.

[0057] Slewing bearings, also known as turntable bearings, rotary bearings, or slewing bearings, are essential transmission components for machinery that requires relative rotational motion between two objects and simultaneously withstands axial force, radial force, and overturning moment.

[0058] The slewing bearing is a single-row, four-point contact ball bearing, consisting of two raceways. It features a compact structure, light weight, and four-point contact between the steel balls and the arc-shaped raceway, enabling it to simultaneously withstand axial force, radial force, and overturning moment. It is suitable for use in rotary conveyors, welding manipulators, small and medium-sized cranes, excavators, and other construction machinery.

[0059] Preferably, the eight rotating paddles 33 are evenly distributed along the circumference of the first slewing bearing 32.

[0060] Rotating the paddle 33 allows it to rotate in the flow of water, providing power for the movement of the transmission device 8.

[0061] A wind sensor can be installed above the rotating paddle 33. The wind sensor can transmit the power of the wind to the transmission device 8 through the rotating paddle 33.

[0062] Preferred, such as Figure 4 , Figure 5 and Figure 6As shown, the transmission device 8 includes a first spur gear 801, a central gear 802, a second spur gear 803, a first one-way ratchet assembly 804, a second one-way ratchet assembly 805, and a ratchet disc 806. The lower part of the first spur gear 801 is engaged with the central gear 802, and the lower part of the central gear 802 is engaged with the second spur gear 803. The first one-way ratchet assembly 804 is fixed to the lower surface of the first spur gear 801, and the second one-way ratchet assembly 805 is fixed to the lower surface of the second spur gear 803. Both the first one-way ratchet assembly 804 and the second one-way ratchet assembly 805 are in contact with the ratchet disc 806.

[0063] Rotating the paddle 33 causes the first spur gear 801 to rotate, which in turn causes the intermediate gear 802 to rotate. The intermediate gear 802 then causes the second spur gear 803 to rotate. The first spur gear 801 causes the first one-way ratchet assembly 804 to rotate, and the second spur gear 803 causes the second one-way ratchet assembly 805 to rotate. The first one-way ratchet assembly 804 and the second one-way ratchet assembly 805 move in opposite directions. When the first one-way ratchet assembly 804 moves in the forward direction, it causes the ratchet 806 to move in the forward direction. When the first one-way ratchet assembly 804 moves in the reverse direction, the second one-way ratchet assembly 805 moves in the forward direction. The second one-way ratchet assembly 805 then causes the ratchet 806 to move in the forward direction. In other words, when the paddle 33 is rotated to cause the first spur gear 801 to move in either the forward or reverse direction, the ratchet 806 moves in the forward direction.

[0064] Preferably, the first straight toothed disk 801 is fixedly connected to the rotating paddle 33.

[0065] The first spur gear 801 rotates under the drive of the rotating paddle 33, and at the same time, the first spur gear 801 can rotate around the lifting column 7 under the support of the first slewing bearing.

[0066] Preferably, a second slewing bearing is mounted laterally on the second spur gear disc 803, and the second slewing bearing is fixedly connected to the lifting column 7 via a second connecting block.

[0067] The second spur gear 803 can rotate around the lifting column 7 under the action of the second slewing bearing.

[0068] Preferably, a third slewing bearing is mounted laterally on the ratchet disc 806, and the third slewing bearing is fixedly connected to the lifting column 7 via a third connecting block.

[0069] The ratchet disc 806 can rotate around the lifting column 7 under the action of the third slewing bearing.

[0070] Preferably, the first one-way ratchet assembly 804 includes a first fixed vertical rod, a first rotating shaft, a first ratchet block, and a first spring; one side of the first rotating shaft is installed on the lower side of the first fixed vertical rod, the first ratchet block is installed on the other side of the first rotating shaft, and the first spring is installed between the upper end of the first ratchet block and the side end of the first fixed vertical rod.

[0071] Preferably, the second one-way ratchet assembly 805 includes a second fixed vertical rod, a second rotating shaft, a second ratchet block, and a second spring. The second rotating shaft is mounted on one side of the lower part of the second fixed vertical rod, and the second ratchet block is mounted on the other side of the second rotating shaft. The second spring is mounted between the upper end of the second ratchet block and the side end of the second fixed vertical rod.

[0072] Preferred, such as Figure 7 As shown, the intermittent release device 9 includes a rotating actuator 901, a positioning pin groove 902, a pin assembly 903, a first fixing post 904, an arc-shaped rod 905, an arc-shaped hollow rod 906, a tension spring, and a second fixing post 907. The rotating actuator 901 has one positioning pin groove 902 on its inner side, and four pin assemblies 903 are in contact with the inner side of the rotating actuator 901. The second fixing post 907 is fixed to the upper surface of the rotating actuator 901. An arc-shaped hollow rod 906 is fixed to one side of the second fixing post 907. One end of the tension spring is fixed inside the arc-shaped hollow rod 906, and the other end of the tension spring is fixed to the arc-shaped rod 905. The arc-shaped rod 905 and the arc-shaped hollow rod 906 are slidably connected, and the first fixing post 904 is fixed to the end of the arc-shaped rod 905.

[0073] The ratchet disc 806 drives the first fixed post 904 to rotate, which in turn drives the arc-shaped rod 905 to rotate. The arc-shaped rod 905 pulls the tension spring to extend and store force. When the first fixed post 904 rotates to the position of the positioning pin groove 902, the pin assembly 903 in the positioning pin groove 902 is pushed out of the positioning pin groove 902 by the first fixed post 904, and the rotation limit of the rotating execution disc 901 disappears. The tension spring drives the rotating execution disc 901 to rotate through the arc-shaped hollow rod 906 and the second fixed post 907 until the next pin assembly 903 is inserted into the positioning pin groove 902, thus realizing the intermittent rotation of the rotating execution disc 901.

[0074] Preferably, the pin assembly 903 includes a wedge block, a limiting baffle, and a telescopic spring; the wedge block is connected to the lifting column 7 via the telescopic spring, the two sides of the wedge block are slidably connected to the limiting baffle, and the limiting baffle is fixedly connected to the lifting column 7.

[0075] Preferably, the first fixing post 904 is fixedly connected to the ratchet disc 806.

[0076] Preferably, when the first fixing post 904 rotates to the position of the positioning pin groove 902, the first fixing post 904 can drive the pin assembly 903 located in the positioning pin groove 902 to exit the positioning pin groove 902.

[0077] The transmission device 8 and the intermittent release device 9 are mechanical transmission structures, and are positioned above the bottom of the floating water tank. Therefore, the parts used for transmission will not come into direct contact with the water, which can ensure the service life of the transmission device 8 and the intermittent release device 9.

[0078] Preferably, the cleaning device 4 includes a cleaning brush 41 and a cleaning rotating rod 42, the cleaning rotating rod 42 being fixedly connected to the ratchet disc 806, and the cleaning brush 41 being slidably connected to the cleaning rotating rod 42.

[0079] The cleaning rotating rod 42 rotates intermittently under the drive of the ratchet disc 806, and the cleaning brush 41 rotates intermittently under the drive of the cleaning rotating rod 42, so as to clean the display base 1.

[0080] The self-cleaning floating platform that can change height with the water level provided in this embodiment, through the arrangement of the rotating device 3, cleaning device 4, floating water tank 5, positioning column 6, lifting column 7, transmission device 8 and intermittent release device 9, enables the device to collect the power of water flow or wind. When the power collected is enough for the cleaning device 4 to rotate at a certain angle, the power is released, and the cleaning device 4 cleans the display base 1. At the same time, by adjusting the proportion of gas in the floating water tank 5, the display platform 2 can always float on the water surface, avoiding the exposure of the floating water tank 5 and other structures under the display platform 2, which would affect the aesthetics.

[0081] Example 2

[0082] Another specific embodiment of the present invention, such as Figure 8 As shown, a side cleaning device 10 is added to the first embodiment. The side cleaning device 10 is fixed on the rotating paddle 33. The side cleaning device 10 includes a cleaning brush assembly 1001 and a cleaning scraper assembly 1002.

[0083] The cleaning brush assembly, such as Figure 9 As shown, it includes a cleaning brush, a first connecting frame, and a first clamping bolt. The cleaning brush is fixedly connected to the first connecting frame, and the first connecting frame has a threaded hole. The first clamping bolt and the first connecting frame are connected by threads.

[0084] The cleaning scraping component, such as Figure 10As shown, it includes a cleaning scraper, a second connecting frame, and a second clamping bolt. The cleaning scraper is fixedly connected to the second connecting frame, which has a threaded hole. The second clamping bolt and the second connecting frame are connected by threads.

[0085] The side cleaning device 10 can rotate along with the rotating device 3, so the cleaning brush and cleaning scraper of the side cleaning device 10 can clean the side of the display stand 2 as the rotating device 3 rotates.

[0086] Due to the undulation of the water surface or prolonged contact with water, the sides of display stand 2 are prone to the growth of moss and other substances that affect the appearance of display stand 2. The installation of the side cleaning device 10 effectively prevents the adhesion of moss and other substances.

[0087] Example 3

[0088] Another specific embodiment of the present invention, such as Figure 11 and Figure 12 As shown, a stiffening device 11 is added between the transmission device 8 and the intermittent release device 9 in Embodiment 1 or Embodiment 2, and the ratchet disc 806 is replaced so that the direction of the teeth of this ratchet disc 806 is opposite to the direction of the teeth of the ratchet disc 806 in Embodiment 1 and Embodiment 2.

[0089] The stiffening device 11 includes an active rotating housing 1101, a passive rotating housing 1102, an active rotating bevel gear ring 1103, a passive rotating bevel gear ring 1104, a transfer transmission housing 1105, a transfer bearing 1106, an active transfer bevel gear 1107, a transfer transmission shaft 1108, a passive transfer bevel gear 1109, and a transfer fixing rod 1110.

[0090] An active rotating bevel gear ring 1103 is fixed inside the active rotating housing 1101. The active rotating bevel gear ring 1103 meshes with the active intermediate rotating bevel gear 1107. One side of the active intermediate rotating bevel gear 1107 is fixedly connected to one end of the intermediate rotating drive shaft 1108. The other end of the intermediate rotating drive shaft 1108 is fixedly connected to the passive intermediate rotating bevel gear 1109. The passive intermediate rotating bevel gear 1109 meshes with the passive rotating bevel gear ring 1104. The passive rotating housing 1102 is fixed to the outside of the passive rotating bevel gear ring 1104.

[0091] The diameter of the active rotating bevel gear 1107 is larger than the diameter of the passive rotating bevel gear 1109.

[0092] The transfer bearing 1106 is sleeved on the outer side of the transfer drive shaft 1108, the transfer housing 1105 is fixed on the outer side of the transfer bearing 1106, and the transfer fixing rod 1110 is fixed on the inner side of the transfer housing 1105.

[0093] The active rotating housing 1101 is fixedly connected to the ratchet disc 806 of the transmission device 8.

[0094] The passive rotating housing 1102 is fixedly connected to the first fixed column 904 of the intermittent release device 9.

[0095] Since the direction of the teeth of the ratchet disc in this embodiment is opposite to the direction of the teeth of the ratchet disc 806 in Embodiment 1 and Embodiment 2, when the paddle 33 is rotated to drive the first straight tooth disc 801 to move in the forward or reverse direction, the ratchet disc 806 moves in the reverse direction.

[0096] The stiffening device 11 has the function of increasing the output torque. The ratchet disc 806 drives the fixedly connected active rotating housing 1101 to rotate in the opposite direction. The active rotating housing 1101 drives the active rotating bevel gear ring 1103 to rotate in the opposite direction. The active rotating bevel gear ring 1103 drives the passive rotating bevel gear ring 1104 to rotate in the forward direction through the active intermediate rotating bevel gear 1107, the intermediate rotating transmission shaft 1108 and the passive intermediate rotating bevel gear 1109. Since the diameter of the active intermediate rotating bevel gear 1107 is larger than the diameter of the passive intermediate rotating bevel gear 1109, the output speed of the stiffening device 11 decreases and the torque increases.

[0097] Compared to Embodiments 1 and 2, this embodiment can still trigger the cleaning device 4 to clean the display base 1 in an environment with low water flow velocity.

[0098] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
