[0028] The present invention has the following beneficial effects:

[0029] 1. For this waterproof distribution box, a water trough is provided at the top of the box body. A corrugated pipe is installed at the bottom of the water trough. One end of the corrugated pipe is connected to the water trough, and the other end is connected to a water tank. In rainy weather, the rainwater received by the water trough flows into the water tank through the corrugated pipe. A drain pipe is provided at the bottom of the water tank. When the rain is heavy, the water inlet speed of the water tank will be greater than the drainage speed of the water tank. At this time, the gravity of the water tank increases, and the water tank moves downward against the tension of the first tension spring. And through the transmission of the first rack and the first gear by the water tank, the second rack is driven to move downward, further driving the baffle to move downward and covering the ventilation plate. When the rain weakens, the drainage speed of the water tank is greater than the water inlet speed, and the gravity of the water tank gradually decreases. Under the tension of the first tension spring, the water tank moves upward and resets. At this time, the baffle moves upward synchronously, and the ventilation plate conducts normal ventilation and heat dissipation. When it is rainy, this device automatically blocks the rainwater with the baffle to prevent the rainwater from contacting the electrical components and prevent the electrical components from short-circuiting and corroding, thereby improving the safety and reliability of the distribution box.

[0030] 2. For this waterproof distribution box, a brush plate is provided inside the box body. A second slider is provided on the brush plate. When the baffle moves downward, the limiting block and the second slider are in contact, thereby driving the brush plate to move downward. At the same time, the second tension spring is stretched and stores energy. During the downward movement of the brush plate, the brush head cleans the ventilation plate. In addition, the second slider is slidably installed in the second sleeve, and a contact block is provided directly below the second slider. When the brush plate moves to the bottom, the contact block contacts the second slider, and the second slider moves into the second sleeve, so that the limiting block releases the limiting effect on the second slider. Therefore, the brush plate quickly moves upward under the action of the second tension spring and cleans the ventilation plate again, thereby increasing the practicability of this device.

[0031] Moreover, a first convex block is provided at one end of the brush plate. During the up and down movement of the brush plate, the first convex block and the second convex block are in sliding contact. Thus, while the brush plate moves up and down, it can also reciprocate to both sides, making the cleaning path of the brush head on the ventilation plate change from a straight line to a wavy line, increasing the cleaning area of the brush head, and further improving the cleaning effect on the ventilation plate and increasing the practicability of this device.

[0032] 3. For this waterproof distribution box, a filter plate for filtering debris is hinged above the water tank. The filter plate can prevent debris such as fallen leaves from blocking the corrugated pipe, thus ensuring the normal function of the device. In addition, a third slide rail is installed at the bottom of the filter plate, and a third slider is slidably installed in the third slide rail. A connecting rod is hinged on the third slider, and the bottom end of the connecting rod abuts against the rotating plate. Therefore, when the baffle moves upward, the rotating plate drives the connecting rod to move upward, so that the filter plate rotates upward, causing the debris on the filter plate to slide off. Moreover, a mounting plate is installed outside the water tank, and a plurality of third convex blocks are arc-arrayed on the mounting plate. The third convex blocks are in sliding contact with one end of the filter plate. During the rotation of the filter plate, under the action of the third convex blocks, the filter plate can vibrate, so that the debris on the filter plate vibrates and slides off, preventing the debris from falling into the water tank and blocking the corrugated pipe, ensuring the normal function of the device and improving the reliability of the device during use.

Detailed implementation manners

[0049] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0050] Embodiment 1. The purpose of this embodiment is to facilitate the solution of the problems that in the daily use of existing distribution boxes, especially in rainy weather, moisture is easily introduced into the interior of the distribution box through the ventilation plate and comes into contact with electrical components, resulting in problems such as short circuits and corrosion of electrical components, affecting the safety and reliability of the distribution box. Please refer to Figures 1 to 15, A waterproof distribution box, including a box body 100, a door panel 101 is hinged on the box body 100, a ventilation plate 102 is arranged on the side of the box body 100, a water tank 203 is slidably installed on the outside of the box body 100, a first rack 209 is installed on the side of the water tank 203, a rotating shaft 211 is rotatably installed on one side of the box body 100, a first gear 217 is installed at one end of the rotating shaft 211, the first gear 217 meshes with the first rack 209, a pair of second slide rails 214 are arranged inside the box body 100, a baffle 213 is slidably installed in the second slide rails 214, a cross bar 212 is installed on the baffle 213, a second rack 210 is installed at one end of the cross bar 212, a second gear 218 is installed at one end of the rotating shaft 211, and the second gear 218 meshes with the second rack 210.

[0051] Specifically, under normal conditions, the baffle 213 is located above the ventilation plate 102. When it rains, the water tank 203 is filled with rainwater, and the water tank 203 drives the baffle 213 to move downward, and the baffle 213 shields the ventilation plate 102.

[0052] Specifically, please refer to Figure 1 , Figure 2 , A pair of first slide rails 207 are installed on the outside of the box body 100, a first slider 219 is arranged on one side of the water tank 203, the first slider 219 is slidably installed in the first slide rails 207, a limit plate 208 is installed at the bottom end of the first slide rails 207. When the water tank 203 reaches the lowest position, the water tank 203 abuts against the limit plate 208. The limit plate 208 can play a role in limiting the water tank 203. At the same time, when the water tank 203 reaches the lowest position, the limit plate 208 supports the water tank 203.

[0053] In addition, a water trough 201 is arranged on the top of the box body 100. The water trough 201 is used to increase the rainwater receiving area and introduce the rainwater into the water tank 203. A corrugated pipe 202 is installed at the bottom of the water trough 201. One end of the corrugated pipe 202 is communicated with the water trough 201, and the other end of the corrugated pipe 202 is communicated with the water tank 203. The corrugated pipe 202 can be stretched. Therefore, during the up and down movement of the water tank 203, it is always ensured that one end of the corrugated pipe 202 is communicated with the water trough 201 and the other end of the corrugated pipe 202 is communicated with the water tank 203.

[0054] In addition, please refer to Figure 4 , A first sleeve 205 is installed at the bottom of the water trough 201. A first tension spring 220 is arranged inside the first sleeve 205. A moving rod 206 is arranged on the top of the water tank 203. The moving rod 206 is slidably installed in the first sleeve 205, and one end of the moving rod 206 is fixedly connected with the first tension spring 220. A drain pipe 204 is arranged at the bottom of the water tank 203. When the drainage speed of the drain pipe 204 is greater than the water inlet speed of the corrugated pipe 202, the water tank 203 is reset under the action of the first tension spring 220.

[0055] Moreover, a water-dispersing seam 103 is formed on one side of the box body 100. The water-dispersing seam 103 is located below the ventilation plate 102. An arc-shaped plate 215 is installed inside the box body 100. The arc-shaped plate 215 is arranged adjacent to the water-dispersing seam 103. Vertical plates 216 are respectively installed at both ends of the arc-shaped plate 215. In rainy weather, rainwater flows along the baffle 213 onto the arc-shaped plate 215, and the rainwater flows out of the box body 100 through the water-dispersing seam 103.

[0056] In this embodiment: a water tank 201 is arranged at the top of the box body 100. A corrugated pipe 202 is installed at the bottom of the water tank 201. One end of the corrugated pipe 202 is communicated with the water tank 201, and the other end of the corrugated pipe 202 is communicated with a water tank 203. In rainy weather, the water tank 201 receives rainwater and flows the rainwater into the water tank 203 through the corrugated pipe 202. A drain pipe 204 is arranged at the bottom of the water tank 203. When the rain is heavy, the water inlet speed of the water tank 203 will be greater than the water drainage speed of the water tank 203. At this time, the gravity of the water tank 203 increases, and the water tank 203 moves downward against the pulling force of the first tension spring 220. And through the transmission of the first rack 209 and the first gear 217 by the water tank 203, the second rack 210 is driven to move downward, further driving the baffle 213 to move downward and covering the ventilation plate 102. When the rain weakens, the water drainage speed of the water tank 203 is greater than the water inlet speed, and the gravity of the water tank 203 gradually decreases. Under the pulling force of the first tension spring 220, the water tank 203 moves upward and resets. At this time, the baffle 213 moves upward synchronously, and the ventilation plate 102 conducts normal ventilation and heat dissipation. When in rainy weather, this device automatically blocks rainwater by the baffle 213, preventing the rainwater from contacting the electrical components and preventing the electrical components from being short-circuited and corroded, thereby improving the safety and reliability of the electric box.

[0057] Embodiment 2 aims to facilitate the solution of the problem of cleaning the ventilation plate. This embodiment is an improvement made on the basis of Embodiment 1. Specifically, please refer to Figures 1 to 15 , a second clamping plate 316 is installed inside the box body 100. A brush plate 301 is slidably installed on one side of the second clamping plate 316. A first clamping plate 315 for limiting the brush plate 301 is arranged on one side of the brush plate 301. A plurality of brush heads 313 are equidistantly arranged on the brush plate 301. A pull ring 302 is installed at the top end of the brush plate 301. A second tension spring 304 is arranged inside the box body 100. One end of the second tension spring 304 is installed with a pull rope 303. One end of the pull rope 303 is fixedly connected with the pull ring 302. A second slider 310 is installed on the side of the brush plate 301. A limiting block 317 is installed on one side of the baffle 213. The limiting block 317 intermittently abuts against the second slider 310.

[0058] Therefore, when the baffle 213 moves downward, the baffle 213 drives the brush plate 301 to move downward through the contact between the limit block 317 and the second slider 310, and the second tension spring 304 is stretched and stores energy. At the same time, the brush head 313 cleans the ventilation plate 102.

[0059] Please refer to Figure 10 、 Figure 11 , a second sleeve 314 is provided on the brush plate 301, a compression spring 318 is installed in the second sleeve 314, the second slider 310 is slidably installed in the second sleeve 314, and the second slider 310 contacts the compression spring 318. A contact block 311 is further provided inside the box body 100, the contact block 311 is located directly below the second slider 310, and the cross-sections of the second slider 310 and the limit block 317 are both triangular. When the brush plate 301 moves to the bottommost position, the contact block 311 contacts the second slider 310, and the limit block 317 releases the restriction on the second slider 310.

[0060] In addition, please refer to Figure 7 , a corrugated plate 312 is provided inside the box body 100, a plurality of second protrusions 306 are equidistantly arranged on the corrugated plate 312, a first protrusion 305 is provided at one end of the brush plate 301, and the first protrusion 305 is in sliding contact with the second protrusion 306. A buffer spring 307 is provided inside the box body 100, one end of the buffer spring 307 is provided with a buffer plate 308, one end of the brush plate 301 contacts the buffer plate 308, and a support plate 309 is installed inside the box body 100, and the support plate 309 is located below the buffer plate 308. Therefore, under the action of the buffer plate 308 and the second protrusion 306, the brush plate 301 moves reciprocally on both sides while moving up and down.

[0061] In this embodiment: a brush plate 301 is provided inside the box body 100, and a second slider 310 is provided on the brush plate 301. When the baffle 213 moves downward, the limit block 317 contacts the second slider 310, thereby driving the brush plate 301 to move downward. At the same time, the second tension spring 304 is stretched and stores energy. During the downward movement of the brush plate 301, the brush head 313 cleans the ventilation plate 102. In addition, the second slider 310 is slidably installed in the second sleeve 314, and a contact block 311 is provided directly below the second slider 310. When the brush plate 301 moves to the bottommost position, the contact block 311 contacts the second slider 310, and the second slider 310 moves into the second sleeve 314, so that the limit block 317 releases the limiting effect on the second slider 310. Therefore, the brush plate 301 quickly moves upward under the action of the second tension spring 304 and cleans the ventilation plate 102 again, thereby increasing the practicability of the device;

[0062] Moreover, a first bump 305 is provided at one end of the brush plate 301. During the up-and-down movement of the brush plate 301, the first bump 305 and the second bump 306 are in sliding contact, so that while the brush plate 301 moves up and down, it can also reciprocate to both sides, making the cleaning path of the brush head 313 on the ventilation plate 102 change from a straight line to a wavy line, increasing the cleaning area of the brush head 313, thereby improving the cleaning effect on the ventilation plate 102 and further increasing the practicability of the device.

[0063] Embodiment 3 aims to facilitate the solution of the problems of preventing sundries from falling into the water tank and preventing the telescopic rod from being blocked. This embodiment is an improvement made on the basis of Embodiment 2. Specifically, please refer to Figures 1 to 15 , a filter plate 401 for filtering sundries is hinged on the water tank 201. A plurality of through holes 402 are provided on the filter plate 401. A third slide rail 406 is installed at the bottom of the filter plate 401. A third slider 409 is slidably installed in the third slide rail 406. A connecting rod 407 is hinged on the third slider 409. The connecting rod 407 slidably penetrates through the water tank 201 and the box body 100.

[0064] A mounting seat 410 is installed on the side of the baffle 213. A torsion spring 412 is installed on the mounting seat 410. A rotating plate 408 is hinged on the mounting seat 410. The rotating plate 408 is fixedly connected to one end of the torsion spring 412. The other end of the torsion spring 412 is fixedly installed on the mounting seat 410. The bottom end of the connecting rod 407 abuts against the rotating plate 408. A rubber strip 403 for buffering the filter plate 401 is also installed at the top end of the water tank 201. A mounting plate 404 is installed outside the water tank 201. A plurality of third bumps 405 are arc-arrayed on the mounting plate 404. The third bumps 405 are in sliding contact with one end of the filter plate 401.

[0065] It should be noted that the supporting force of the rotating plate 408 before rotation can support the connecting rod 407 and at the same time make the filter plate 401 rotate outward from the water tank 201. When the filter plate 401 reaches the maximum rotation angle, the connecting rod 407 cannot move upward continuously. At this time, the torsion spring 412 is distorted and the rotating plate 408 rotates. The connecting rod 407 moves downward without the support of the rotating plate 408. At the same time, the filter plate 401 quickly resets under the action of gravity, and the rubber strip 403 buffers the filter plate 401.

[0066] In this embodiment: Above the water tank 201, a filter plate 401 for filtering debris is hinged. The filter plate 401 can prevent debris such as fallen leaves from blocking the corrugated pipe 202, thus ensuring the normal function of the device. In addition, a third slide rail 406 is installed at the bottom of the filter plate 401. A third slider 409 is slidably installed in the third slide rail 406. A connecting rod 407 is hinged on the third slider 409. The bottom end of the connecting rod 407 abuts against the rotating plate 408. Therefore, when the baffle 213 moves upward, the rotating plate 408 drives the connecting rod 407 to move upward, so that the filter plate 401 rotates upward, and the debris on the filter plate 401 slides off. Moreover, a mounting plate 404 is installed outside the water tank 201. A plurality of third convex blocks 405 are arranged in an arc array on the mounting plate 404. The third convex blocks 405 are in sliding contact with one end of the filter plate 401.
