Prolonged exposure to a humid working environment can cause short circuits and burnout of the light-emitting element circuitry, affecting the normal operation of the floodlight. Utility Model Content
[0004] The purpose of this invention is to solve the problem that when a floodlight is placed on the ground in rainy weather, rainwater may enter the floodlight body through the heat dissipation holes. The prolonged exposure of the interior of the floodlight to a humid working environment can cause short circuits and burnout of the light-emitting element circuitry, thus affecting the normal use of the floodlight. This invention provides a high-power outdoor LED floodlight.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: an outdoor high-power LED floodlight, comprising a housing, wherein a plurality of light-emitting elements are disposed inside the housing, a support rod is rotatably connected to one side of the housing, a wiring sleeve is disposed on one side of the bottom of the housing, and a waterproof device is disposed on the top of the housing by means of a convenient device, the waterproof device comprising a groove plate, the groove plate being fixed to one side of the top of the housing by means of a convenient device, two groove rods being fixedly connected to the inner walls of the groove plate respectively, a sliding plate being slidably connected to the outer surface of the groove rods, and rectangular blocks being fixedly connected to the top two sides of the sliding plate respectively, a rotating shaft being rotatably connected to the two ends of one rectangular block, the two ends of the rotating shaft being rotatably connected to the sides of the two rectangular blocks that are close to each other, a baffle being fixedly connected to the outer surface of the rotating shaft, and coil springs being disposed at the two ends of the rotating shaft, the two ends of the coil springs being fixedly connected to one side of the rotating shaft and one side of the rectangular block respectively, the coil springs being in a compressed state.
[0006] The effect achieved by the above components is as follows: By setting up baffles, when using LED floodlights outdoors in rainy weather, the waterproof device and the channel plate can be installed at the top of the housing with the help of a convenient device. Pulling the two rectangular blocks at the top of the sliding plate controls the sliding plate to slide upward between the channel rods, so that most of the sliding plate slides out of the channel plate. When the baffles on both sides of the sliding plate disengage from the channel plate, the coil springs at both ends of the rotating shaft at the top of the two baffles will return to their original state and push the rotating shaft and the baffles to rotate and unfold away from the sliding plate. Then, the sliding plate is pushed into the channel plate. The top of the housing is protected by the two unfolded baffles, which move rainwater away from the surface of the baffles away from the housing as much as possible, avoiding rainwater from entering the housing through the surface of the housing and causing damage to the internal circuit of the floodlight, affecting normal use. When it is not necessary to protect the housing from rain, pull the sliding plate upward, then push the two baffles to rotate in the direction of the sliding plate and compress the coil springs on the outer surface of the rotating shaft, so that the baffles and the sliding plate fit together. Then push the sliding plate to retract the sliding plate and the baffles into the channel plate.
[0007] Preferably, a sloping groove is provided on one side of the baffle, and a protruding rod is fixedly connected to one end of the inner wall of the sloping groove.
[0008] The effect achieved by the above components is that when rainwater enters the inclined groove on the surface of the baffle, it flows more quickly to the protruding rod and splashes outward through the protruding rod, further preventing rainwater from entering the surface of the housing.
[0009] Preferably, an auxiliary groove is provided on one side of the rectangular block, and an anti-slip sheet is provided on the inner wall of the auxiliary groove.
[0010] The effect achieved by the above components is that when the sliding plate is pulled out from inside the groove, it is more convenient to push the rectangular block to control the movement of the sliding plate by pressing against the anti-slip plate inside the auxiliary groove on one side of the rectangular block, and it is less likely to slip.
[0011] Preferably, positioning rods are fixedly connected to both sides of the bottom end of the sliding plate, and a limiting groove is formed on the outer surface of the groove rod, and the outer surface of the positioning rod slides on the inner wall of the limiting groove.
[0012] The effect achieved by the above components is that when the sliding plate is pulled upward inside the slot, the positioning rod will slide on the inner wall of the limiting slot. The limiting slot and the positioning rod can limit the movement range of the sliding plate and prevent the sliding plate from being pulled out of the slot.
[0013] Preferably, a sealing sheet is fixedly connected to one end of the baffle near the rotating shaft, and the sealing sheet is a rubber sheet made of rubber.
[0014] The effect achieved by the above components is that when the two baffles are unfolded, the sealing plates at one end will fit together, further sealing the position between the two baffles and preventing rainwater from entering the surface of the housing through the space between the two baffles as much as possible.
[0015] Preferably, the convenient device includes two slot blocks, one side of each slot block is fixedly connected to both ends of a slot plate, two through holes are opened on the outer surface of each slot block, and bolts are slidably inserted into the inner wall of each through hole. Two threaded holes are opened on both sides of the top of the housing, and the outer surface of each bolt is threadedly connected to the inner wall of the threaded hole.
[0016] The effect achieved by the above components is as follows: When installing the waterproof device, the bottom end of the groove plate is attached to the top of the shell, so that the two groove blocks are stuck on both sides of the top of the shell, and the through holes on the outer surface of the groove blocks are aligned with the threaded holes on the outer surface of the shell. Then, the bolt is inserted through the through hole into the threaded hole, and the bolt is rotated to connect with the threaded hole. The groove block and groove plate are fixed to one side of the top of the shell. The bolt is rotated to disengage from the threaded hole, and the groove plate is removed to disassemble the waterproof device, thus improving the convenience of using the waterproof device.
[0017] Preferably, two elastic ropes are fixedly connected to one side of the groove block, and the ends of the two elastic ropes away from the groove block are rotatably connected to one end of the bolt.
[0018] The effect achieved by the above components is that by setting elastic ropes, the bolts can always be fixed to one side of the groove block, making it easy to take the bolts out when installing the waterproof device and preventing the bolts from falling off and being lost.
[0019] Preferably, two positioning blocks are fixedly connected to the top two sides of the housing, and the distance between the two positioning blocks is slightly greater than the width of the groove block.
[0020] The effect achieved by the above components is that when the slot blocks and slot plates are installed at the top of the housing, the two slot blocks on both sides of the slot plate can be inserted between the two positioning blocks on both sides of the top of the housing to initially fix the position between the slot blocks and the housing, making it easier to install the slot blocks with bolts.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0022] In this invention, by setting up a waterproof device, when using the floodlight in rainy weather, the position of the sliding plate inside the groove plate is adjusted to unfold the two baffles on the surface of the sliding plate. The two unfolded baffles protect the top of the housing, causing rainwater to move away from the surface of the baffles and away from the housing as much as possible, thus preventing rainwater from entering the housing through the surface of the housing and causing damage to the internal circuitry of the floodlight, which would affect normal use.

[0030] Example 1, such as Figure 1-5As shown, an outdoor high-power LED floodlight includes a housing 1, with several light-emitting elements 4 disposed inside the housing 1. A support rod 5 is rotatably connected to one side of the housing 1, and a junction box 6 is disposed on one side of the bottom of the housing 1. A waterproof device 2 is disposed on the top of the housing 1 by means of a convenient device 3. The waterproof device 2 includes a groove plate 21, which is fixed to one side of the top of the housing 1 by means of the convenient device 3. Two groove rods 22 are fixedly connected to both sides of the inner wall of the groove plate 21, and a sliding plate 23 is slidably connected to the outer surface of the groove rods 22. Rectangular blocks 24 are fixedly connected to both sides of the top of the sliding plate 23, and a rotating shaft 25 is rotatably connected to both ends of each rectangular block 24. A rotating shaft 25 has two ends rotatably connected to the sides of two rectangular blocks 24 that are close to each other. A baffle 26 is fixedly connected to the outer surface of the rotating shaft 25. A coil spring 27 is provided at both ends of the rotating shaft 25. The two ends of the coil spring 27 are fixedly connected to one side of the rotating shaft 25 and one side of the rectangular block 24, respectively. The coil spring 27 is in a compressed state. By setting the baffle 26, when using the LED floodlight outdoors in rainy weather, the waterproof device 2 and the groove plate 21 can be installed at the top of the housing 1 with the help of the convenient device 3. Pulling the two rectangular blocks 24 at the top of the sliding plate 23 controls the sliding plate 23 to slide upward between the groove rods 22, so that most of the sliding plate 23 slides out of the groove plate 21. When the baffles 26 on both sides of the movable plate 23 disengage from the groove plate 21, the coil springs 27 compressed at both ends of the top pivot 25 of the two baffles 26 will return to their original state and push the pivot 25 and the baffles 26 to rotate and unfold away from the sliding plate 23. Then, the sliding plate 23 is pushed into the groove plate 21. The top of the housing 1 is protected by the two unfolded baffles 26, causing rainwater to enter the surface of the baffles 26 and move away from the housing 1. This minimizes the possibility of rainwater entering the interior of the housing 1 through the surface of the housing 1, which could damage the internal wiring of the floodlight and affect normal use. When it is not necessary to protect the housing 1 from rain, pull the sliding plate 23 upward and then push the two baffles 26 away from the groove plate 21. The sliding plate 23 rotates and compresses the coil spring 27 on the outer surface of the rotating shaft 25, so that the baffle 26 and the sliding plate 23 fit together. Then, the sliding plate 23 is pushed to retract the sliding plate 23 and the baffle 26 into the groove plate 21. By setting the waterproof device 2, when the floodlight is used in rainy weather, the two baffles 26 on the surface of the sliding plate 23 are unfolded by adjusting the position of the sliding plate 23 inside the groove plate 21. The two unfolded baffles 26 protect the top of the housing 1, so that rainwater entering the surface of the baffle 26 moves away from the housing 1 as much as possible, avoiding rainwater from entering the interior of the housing 1 through the surface of the housing 1 and causing damage to the internal circuit of the floodlight, thus affecting normal use.
[0031] Reference Figure 2-5As shown in this embodiment: a sloping groove 28 is provided on one side of the baffle 26, and a protruding rod 29 is fixedly connected to one end of the inner wall of the sloping groove 28. When rainwater enters the sloping groove 28 on the surface of the baffle 26, it will flow to the protruding rod 29 more quickly and splash outward through the protruding rod 29, further preventing rainwater from entering the surface of the housing 1. An auxiliary groove 210 is provided on one side of the rectangular block 24, and an anti-slip plate is provided on the inner wall of the auxiliary groove 210. When the sliding plate 23 is pulled out from the inside of the groove plate 21, the rectangular block 24 can be pushed by hand against the anti-slip plate inside the auxiliary groove 210 on one side of the rectangular block 24 to control the movement of the sliding plate 23 more conveniently and less likely to slip.
[0032] Reference Figure 2-5 As shown in this embodiment: positioning rods 211 are fixedly connected to both sides of the bottom end of the sliding plate 23. A limiting groove 212 is opened on the outer surface of the groove rod 22. The outer surface of the positioning rod 211 slides on the inner wall of the limiting groove 212. When the sliding plate 23 is pulled to move upward inside the groove plate 21, the positioning rod 211 will slide on the inner wall of the limiting groove 212. The movement range of the sliding plate 23 can be limited by the limiting groove 212 and the positioning rod 211 to prevent the sliding plate 23 from being pulled out of the groove plate 21. A sealing sheet 213 is fixedly connected to one end of the baffle 26 near the rotating shaft 25. The sealing sheet 213 is a rubber sheet made of rubber. When the two baffles 26 are unfolded, the sealing sheets 213 at one end will stick together to further seal the position between the two baffles 26 and prevent rainwater from entering the surface of the housing 1 through the space between the two baffles 26 as much as possible.
[0033] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown in this embodiment: the convenient device 3 includes two slot blocks 31, one side of each slot block 31 is fixedly connected to both ends of the slot plate 21. Two through holes 32 are opened on the outer surface of the slot block 31, and bolts 33 are slidably inserted into the inner wall of the through holes 32. Two threaded holes 34 are opened on both sides of the top of the housing 1. The outer surface of the bolts 33 is threadedly connected to the inner wall of the threaded holes 34. When installing the waterproof device 2, the bottom end of the slot plate 21 is attached to the top of the housing 1, so that the two slot blocks 31 are stuck on both sides of the top of the housing 1, and the through holes 32 on the outer surface of the slot blocks 31 are aligned with the threaded holes 34 on the outer surface of the housing 1. Then, the bolts 33 are inserted through the through holes 32 into the threaded holes 34. The bolts 33 are rotated so that the bolts 33 are threadedly connected to the inner wall of the threaded holes 34, thus fixing the slot blocks 31 and the slot plate 21 to one side of the top of the housing 1. The bolts 33 are rotated so that the bolts 33 are disengaged from the inside of the threaded holes 34, and then the slot plate 21 is removed to disassemble the waterproof device 2, thereby improving the convenience of using the waterproof device 2.
[0034] Reference Figure 2 , Figure 3, Figure 4 and Figure 6 As shown in this embodiment: two elastic ropes 35 are fixedly connected to one side of the groove block 31. The ends of the two elastic ropes 35 away from the groove block 31 are rotatably connected to one end of the bolt 33. By setting the elastic ropes 35, the bolt 33 can always be fixed to one side of the groove block 31, which is convenient for taking the bolt 33 when installing the waterproof device 2 and prevents the bolt 33 from falling off and being lost. Two positioning blocks 36 are fixedly connected to both sides of the top of the housing 1. The distance between the two positioning blocks 36 is slightly larger than the width of the groove block 31. When the groove block 31 and the groove plate 21 are installed on the top of the housing 1, the two groove blocks 31 on both sides of the groove plate 21 can be inserted between the two positioning blocks 36 on both sides of the top of the housing 1 to initially fix the position between the groove block 31 and the housing 1, which is convenient for installing the groove block 31 with the bolt 33.
[0035] Working principle: When using a high-power LED floodlight, connect the power line to the junction box 6 on one side of the bottom of the housing 1, then place the housing 1 on the ground, and push the support rod 5 to rotate and adjust the angle to support the housing 1. The light is emitted by the light-emitting body 4 inside the housing 1. When using the light in rainy weather, attach the bottom end of the slot plate 21 to the top of the housing 1, so that the two slot blocks 31 are locked on both sides of the top of the housing 1, and align the through hole 32 on the outer surface of the slot block 31 with the threaded hole 34 on the outer surface of the housing 1. Then, insert the bolt 33 through the through hole 32 into the threaded hole 34, and rotate the bolt 33 to connect the bolt 33 with the inner thread of the threaded hole 34, thus fixing the slot block 31 and the slot plate 21 to one side of the top of the housing 1. Pull the two rectangular blocks 24 at the top of the sliding plate 23 to control the sliding plate 23 to slide upward between the slot rod 22, so that the sliding plate 23... Most of the slide plate 23 slides out of the groove plate 21. When the baffles 26 on both sides of the sliding plate 23 disengage from the groove plate 21, the coil springs 27 at both ends of the rotating shaft 25 at the top of the two baffles 26 will return to their original state and push the rotating shaft 25 and the baffles 26 to rotate and unfold away from the sliding plate 23. Then, the sliding plate 23 is pushed into the groove plate 21. The top of the housing 1 is protected by the two unfolded baffles 26, and rainwater enters the surface of the baffles 26 and moves away from the housing 1, so as to avoid rainwater entering the housing 1 through the surface of the housing 1 as much as possible. When it is not necessary to protect the housing 1 from rain, the sliding plate 23 is pulled upward, and the two baffles 26 are pushed to rotate in the direction of the sliding plate 23 and compress the coil springs 27 on the outer surface of the rotating shaft 25, so that the baffles 26 and the sliding plate 23 fit together. Then, the sliding plate 23 is pushed to bring the sliding plate 23 and the baffles 26 into the groove plate 21.
