[0033] As shown in the figure, the LED lamp according to the embodiment of the present application comprises a closed lamp body 2 arranged on a lamp pole 1; Figures 1 to 10

[0034] The inside of the closed lamp body 2 is provided with a circulating pipeline 3, and the inside of the closed lamp body 2 is provided with a transfer box 4, one end of the circulating pipeline 3 extending from the top of the transfer box 4 to the inside, and the other end of the circulating pipeline 3 being connected with the transfer box 4 through a circulating assembly;

[0035] The circulating pipeline 3 is arranged in the inside of the closed lamp body 2 and is attached to the electronic components inside, and water circulation is carried out in the circulating pipeline 3, so that the LED lamp beads in the closed lamp body 2 can be cooled, and the closed lamp body 2 can effectively block the entry of dust and mosquitoes, and the water circulation cooling method can ensure the cooling effect of the closed lamp body 2.

[0036] The inside of the transfer box 4 can be provided with a semiconductor refrigerating fin, and when the water in the circulating pipeline 3 enters the transfer box 4, the water carrying the heat of the LED lamp beads can be cooled by the semiconductor refrigerating fin.

[0037] The circulating assembly comprises a circulating pump 5, a first connecting pipe 6 and a second connecting pipe 7, the circulating pump 5 is arranged on one side of the transfer box 4, one end of the first connecting pipe 6 is connected with the output end of the circulating pump 5, the other end of the first connecting pipe 6 is connected with one end of the circulating pipeline 3, one end of the second connecting pipe 7 extends from the bottom end of the transfer box 4 to the inside, and the other end of the second connecting pipe 7 is fixedly connected with the input end of the circulating pump 5.

[0038] ​One end of the circulation pipe 3 is connected to the inside of the transfer box 4, and the other end is connected to the first connecting pipe 6. The other end of the first connecting pipe 6 is connected to the output end of the circulation pump 5. The input end of the circulation pump 5 is connected to the inside of the transfer box 4 through the second connecting pipe 7.

[0039] When the circulation pump 5 starts, it can draw water out of the transfer box 4 through the second connecting pipe 7 and transport it to the inside of the circulation pipeline 3 through the first connecting pipe 6. Under the pressure of the circulation pump 5, the water entering the circulation pipeline 3 will automatically flow towards the inside of the transfer box 4.

[0040] In a preferred embodiment of the present invention, a filter screen plate 10 is provided inside the transfer box 4. A cleaning block 14 is slidably installed on the top of the filter screen plate 10. Both sides of the bottom end of the cleaning block 14 are provided with impurity inlets 15. A suction pipe 34 is fixedly connected to the cleaning block 14. The other end of the suction pipe 34 is connected to a negative pressure device.

[0041] Since the end of the circulation pipe 3 flowing towards the transfer box 4 extends downward from the top of the transfer box 4 to its interior, the water contains mineral ions such as calcium and magnesium, which may crystallize and precipitate due to changes in temperature and pressure during circulation, forming scale. Therefore, the water entering the transfer box 4 will be filtered through the filter screen 10, which can effectively filter out the scale. At the same time, the filter screen 10 is also equipped with a sliding cleaning block 14, which is attached to the surface of the filter screen 10. When the cleaning block 14 slides, it will scrape the impurities on the surface of the filter screen 10 into the interior of the cleaning block 14 through the impurity inlet 15 at the bottom. The scale that has entered the interior of the cleaning block 14 can be extracted by the negative pressure device and the suction pipe 34, which effectively ensures the flow rate of the filter screen 10.

[0042] In a preferred embodiment of the present invention, a blocking frame 8 is fixedly installed inside the transfer box 4, and a baffle plate 9 is rotatably installed inside the blocking frame 8. The baffle plate 9 is positioned above the filter screen plate 10.

[0043] The baffle plate 9 is set on the inner wall of the baffle frame 8. By controlling the rotation of the baffle plate 9, when both ends of the baffle plate 9 are in contact with the outer wall of the baffle frame 8, the inner cavity of the transfer box 4 can be divided into two. At this time, the water between the baffle plate 9 and the filter screen plate 10 will fall into the bottom of the transfer box 4 through the mesh until there is no water between the filter screen plate 10 and the baffle plate 9. At this time, the cleaning block 14 can be controlled to slide, and the scale on the filter screen plate 10 can be removed in conjunction with the negative pressure device, so as to ensure the flow of the filter screen plate 10 while reducing the loss of circulating water.

[0046] When the filter screen plate 10 has a large amount of scale and the mesh holes are blocked, the water flow gradually decreases until it cannot pass, at this time the water flow under the pressure of the circulating pump 5 will push the filter screen plate 10 to move downward, at this time the toothed plate 30 will be pulled downward through the connecting rope 31, the top pressure spring is deformed and stores elastic potential energy, at the same time the rotating gear 32 is rotated, the control blocking plate 9 is rotated and attached to the blocking frame 8 to block the water flow, at this time part of the accumulated water will be left between the blocking frame 8 and the filter screen plate 10, which can be cleared through the sliding of the cleaning block 14 to dredge the filter screen plate 10.

[0047] As a preferred embodiment in the present application, the end of the blocking plate 9 away from the second rotating rod 29 is fixedly installed with a first rotating rod 22, the outer wall of the first rotating rod 22 is fixedly installed with a ratchet wheel 23, the interior of the transfer box 4 is elastically installed with a ratchet rod 24 for blocking the rotation of the ratchet wheel 23, the outer wall of the first rotating rod 22 is fixedly installed with a coil spring 35, and the other end of the coil spring 35 is fixedly connected with the interior of the transfer box 4.

[0049] The side wall of the ratchet lever 24 is fixedly installed with a transmission rod 25, the outer wall of the transmission rod 25 is slidably installed with a push rod 26, the outer wall of the transmission rod 25 is provided with a spiral groove 27, the inner wall of the push rod 26 is fixedly installed with a guide block 28, and one end of the guide block 28 extends into the spiral groove 27.

[0052] When the filter screen plate 10 is blocked, the impact of the water flow causes the filter screen plate 10 to slide downwards until the filter screen plate 10 slides to be attached to the transmission block 11, at this time, the reciprocating screw rod 12 is controlled to slide, the transmission block 11 is driven to reciprocally slide at the bottom end of the filter screen plate 10 until the transmission block 11 and the cleaning block 14 are attracted to each other by magnetic force, at this time, the transmission block 11 slides to drive the cleaning block 14 to synchronously slide.

[0054] When the circulating pump 5 drives the second connecting pipe 7 to extract the circulating water of the transfer box 4, the water flow will impact the water wheel blade 16 to rotate, at the same time, drive the second connecting rod 17 to rotate, drive the fourth bevel gear 18 to drive the third bevel gear 19 to rotate, at this time, the first connecting rod 33 will drive the second bevel gear 20 to rotate, finally drive the first bevel gear 21 to rotate, make the reciprocating wire rod 12 always drive the transmission block 11 to reciprocate, when sliding under the filter screen plate 10, the transmission block 11 can cooperate with the cleaning block 14 at any time.
