DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] Reference Figure 1-Figure 7 , an outdoor waterproof power distribution cabinet, comprising a cabinet body 1 and a cabinet door 31 rotatably mounted on the cabinet body 1, a plurality of strip-shaped heat dissipation holes 2 are provided on both sides of the cabinet body 1, a mounting seat 3 is fixedly mounted inside the cabinet body 1, and vertical rods 4 are vertically slidably mounted on both sides of the cabinet body 1 through a sliding assembly, the sliding assembly comprises a mounting block 11 fixedly mounted on the inner wall of the cabinet body 1, a slider 12 fixedly mounted on the vertical rod 4 and a second telescopic spring 13 fixedly mounted on the slider 12, a slide groove is provided on the mounting block 11, the slider 12 is slidably mounted in the slide groove, one end of the second telescopic spring 13 is fixedly connected to the inner wall of the slide groove, partitions 5 are horizontally fixedly mounted on the two vertical rods 4, the plurality of partitions 5 are respectively located directly above the plurality of heat dissipation holes 2, the surface of the partitions 5 is in sliding contact with the inner wall of the cabinet body 1, and positioning blocks 15 are fixedly mounted on the inner walls of both sides of the cabinet body 1, and the positioning blocks 15 are located directly below the vertical rod 4.

[0031] The mounting base 3 is used for mounting switchgear, measuring instruments, protective electrical appliances and auxiliary equipment in the power distribution cabinet. As shown in the figure, the length and width of the partition 5 are both greater than the length and width of the heat dissipation hole 2. The vertical rod 4 is mounted on the inner wall of the cabinet 1 through the mounting block 11, the slider 12 and the second telescopic spring 13. The slider 12 can move in the slide groove opened on the mounting block 11. In the absence of rainfall, under the action of the elastic force of the second telescopic spring 13, the slider 12 is located directly above the slide groove, and multiple partitions 5 are respectively located above the corresponding heat dissipation holes 2. When the vertical rod 4 moves vertically downward and one end contacts the positioning block 15, the vertical rod 4 will simultaneously drive multiple partitions 5 to move vertically downward, and the partitions 5 will just block the heat dissipation holes 2 to prevent external rainwater from passing through the heat dissipation holes 2 into the cabinet 1.

[0032] A water collecting box 6 is provided at the upper end of the cabinet 1, and a water outlet hole 7 is opened on the side of the water collecting box 6. A plurality of movable rods 8 are vertically fixedly installed on the lower surface of the water collecting box 6. A plurality of movable holes are opened at the upper end of the cabinet 1, and the plurality of movable rods 8 are slidably inserted in the plurality of movable holes, and a strip rod 9 is fixedly installed at the lower end of every two movable rods 8. A first telescopic spring 10 is sleeved on the plurality of strip rods 9, and the two ends of the first telescopic spring 10 are respectively fixedly connected to the inner wall of the cabinet 1 and the surface of the strip rod 9. A transmission assembly for driving the vertical rod 4 to move vertically downward is provided on the strip rod 9, and the transmission assembly includes an L-shaped transmission rod 14 fixedly installed on the strip rod 9, and the end of the transmission rod 14 away from the strip rod 9 is fixedly connected to the vertical rod 4.

[0033] The water collecting box 6 is installed at the upper end of the cabinet 1, and the upper surface area is larger than the area of ​​the upper end of the water collecting box 6, which can play a certain role in keeping out rain. When the outdoor rainfall is small, the heat dissipation hole 2 itself has a certain thickness, and the rainwater cannot pass through the heat dissipation hole 2. When the outdoor rainfall increases, the rainwater may pass through the heat dissipation hole 2 and enter the cabinet 1. When the rainfall increases, the rainwater will be quickly collected in the water collecting box 6, and a small amount of rainwater will be discharged from the water outlet 7. The speed of rainwater collection is much faster than the speed of water discharge from the water outlet 7. At this time, the water in the water collecting box 6 The rain will gradually become larger. When the water collecting box 6 is full of rainwater, the water collecting box 6 will be driven to move vertically downward under the action of the gravity of the rainwater. The moving rod 8 will move vertically downward in the moving hole. The first telescopic spring 10 will be stretched. At this time, the strip rod 9 will drive the vertical rod 4 to move vertically downward through the transmission rod 14 until the lower end of the vertical rod 4 contacts the positioning block 15. The partition 5 blocks the heat dissipation holes 2 and can automatically close multiple heat dissipation holes 2 to prevent rainwater from entering the distribution cabinet through the heat dissipation holes 2, causing damage to the electrical components in the distribution cabinet, thereby improving the waterproofness of the distribution cabinet.

[0034] A transfer tube 16 is fixedly installed on the rear side of the cabinet 1, and the transfer tube 16 is connected to the water outlet 7 through a connecting hose 17. A plurality of cooling tubes 18 are fixedly installed in the cabinet 1, one end of the cooling tube 18 is connected to the transfer tube 16, and the other end extends out of the cabinet 1.

[0035] When multiple heat dissipation holes 2 are blocked by the partition 5, rainwater discharged from the water outlet 7 in the water collecting tank 6 will flow into the transfer tube 16 through the connecting hose 17, and then flow into the cooling pipe 18. Through the cooling pipe 18, the rainwater will flow in the cabinet 1, absorb the heat generated inside the cabinet 1, and then be discharged from the cabinet 1 through the other end of the cooling pipe 18, which can play a cooling role when multiple heat dissipation holes 2 are closed.

[0036] Water collecting boxes 19 are fixedly installed on both sides of the cabinet body 1, and the water collecting boxes 19 are located directly below the multiple heat dissipation holes 2. Multiple drainage holes connected to the water collecting boxes 19 are opened on the side of the cabinet body 1, and drainage pipes 20 are fixedly installed in the multiple drainage holes. Multiple drainage grooves 28 are opened on the inner walls on both sides of the cabinet body 1, and the drainage grooves 28 are located between the heat dissipation holes 2 and the water collecting boxes 19.

[0037] When the partition 5 blocks the heat dissipation hole 2, there will still be a small gap between the partition 5 and the heat dissipation hole 2. In the case of heavy rainfall, a small amount of rainwater will pass through the gap and flow into the cabinet 1 along the inner wall of the cabinet 1. When the rainwater flows along the inner wall of the cabinet 1, it will enter the water collecting box 19 under the action of drainage by multiple drainage grooves 28, and then be discharged to the outside of the cabinet 1 through the drain pipe 20.

[0038] Water-absorbing cotton 21 is placed in the water collecting box 19, and a squeezing assembly for squeezing the water-absorbing cotton 21 is provided in the water collecting box 19. The squeezing assembly includes a squeezing plate 22 slidably installed in the water collecting box 19, a cylindrical rod 23 fixedly installed on the squeezing plate 22, and a moving part for driving the cylindrical rod 23 to move horizontally. The water-absorbing cotton 21 is located between the squeezing plate 22 and the inner wall of the cabinet 1. A circular hole is opened on the side of the water collecting box 19, and the cylindrical rod 23 is horizontally slidably installed in the circular hole.

[0039] The moving parts include a trapezoidal block 24 fixedly mounted at one end of the cylindrical rod 23, a third telescopic spring 25 sleeved on the cylindrical rod 23, a supporting rod 26 fixedly mounted at one end of the vertical rod 4 and a rotating column 27 rotatably mounted on the supporting rod 26 away from the end of the vertical rod 4, the rotating column 27 is in rolling contact with the trapezoidal block 24, and the two ends of the third telescopic spring 25 are respectively fixedly connected to the trapezoidal block 24 and the inner wall of the water collecting box 19.

[0040] The absorbent cotton 21 is placed between the extrusion plate 22 and the inner wall of the cabinet 1. When the multiple heat dissipation holes 2 are open, under the action of the elastic force of the third telescopic spring 25, the cylindrical rod 23 tends to move away from the extrusion plate 22. At this time, the extrusion plate 22 does not squeeze the absorbent cotton 21, and the absorbent cotton 21 is in an initial state. Rainwater entering the water collecting box 19 will be absorbed by the absorbent cotton 21 to prevent rainwater from shaking and spilling out of the water collecting box 19.

[0041] When the outdoor rainfall stops, the rainwater in the water collecting box 6 will be continuously discharged through the water outlet 7, and the weight of the rainwater in the water collecting box 6 will continue to decrease. At this time, under the action of the elastic force of the first telescopic spring 10, the moving rod 8 and the strip rod 9 will be driven to move vertically upward. The strip rod 9 will drive the vertical rod 4 to move vertically upward through the transmission rod 14, and drive multiple partitions 5 to move vertically upward to open multiple heat dissipation holes 2. While the vertical rod 4 moves vertically upward, it will drive the rotating column 27 to move vertically upward through the support rod 26. The rotating column 27 is in rolling contact with the inclined surface of the trapezoidal block 24. In the process of moving vertically upward, the rotating column 27 will drive the cylindrical rod 23 to move toward the extrusion plate 22 through the trapezoidal block 24. The third telescopic spring 25 is compressed. At this time, the extrusion plate 22 will squeeze the absorbent cotton 21, and the rainwater absorbed by the absorbent cotton 21 can be squeezed out and discharged through the drain pipe 20, thereby further improving the waterproofness of the distribution cabinet.

[0042] A base 29 is fixedly installed at the lower end of the cabinet body 1, and a plurality of positioning rods 30 are vertically fixedly installed on the lower surface of the base 29. The plurality of positioning rods 30 installed on the base 29 are deeply inserted into the soil, which can improve the stability of the installation of the distribution cabinet and prevent the distribution cabinet from being blown away in windy weather.

[0043] In the present invention, when the rainfall increases, rainwater will be quickly collected in the water collecting box 6, and a small amount of rainwater will be discharged from the water outlet 7. The speed of rainwater collection is much greater than the speed of rainwater discharge from the water outlet 7. At this time, the rainwater in the water collecting box 6 will gradually increase. Under the action of the gravity of the rainwater, the water collecting box 6 will be driven to move vertically downward, and the moving rod 8 will move vertically downward in the moving hole. At this time, the strip rod 9 will drive the vertical rod 4 to move vertically downward through the transmission assembly. When the vertical rod 4 moves vertically downward and one end contacts the positioning block 15, the vertical rod 4 will simultaneously drive multiple partitions 5 to move vertically downward, and the partitions 5 will just block the heat dissipation holes 2, and can automatically close multiple heat dissipation holes 2, thereby preventing rainwater from entering the distribution cabinet through the heat dissipation holes 2 and causing damage to the electrical components in the distribution cabinet, thereby improving the waterproofness of the distribution cabinet.

[0044] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
