Specific implementation manners

[0027] A high-voltage distribution box includes a back plate 11 provided with a hanging plate 14 and end plates 13 arranged on the upper and lower sides of the back plate 11. Two vertical plates 12 are provided on the back plate 11 and the two end plates 13. A side door 41 is rotatably connected to each vertical plate 12. Two blocking strips 16 are symmetrically arranged on the two end plates 13. A front plate 51 is detachably connected to the two blocking strips 16. Two pairs of limiting strips 15 are symmetrically arranged on the two end plates 13. A partition frame 21 is slidably connected to the two pairs of limiting strips 15. The distance in the front-back direction in the middle of the two end plates 13 is greater than the distance between the two sides, ensuring that the distance in the front-back direction between the two vertical plates 12 will not hinder the operator from installing an electrical installation rail on the hanging plate 14 in the distribution box and installing or operating electronic components on the electrical installation rail, thus increasing the convenience of operation inside the distribution box. When an operation needs to be performed on the hanging plate 14, rotate the partition frame 21, slide the partition frame 21 out of the two pairs of limiting strips 15, and after removing the partition frame 21, it is convenient to operate the electronic components on the hanging plate 14 and the two vertical plates 12. The corresponding positions on the partition frame 21 can be used to place high-heat-generating electronic components for isolation, enabling separate arrangement of high-heat-generating electronic components and other electronic components, and preventing the heat dissipated by the high-heat-generating electronic components from affecting the normal use of other electronic components. The two side doors 41 can open and close the edges of the two vertical plates 12, protecting the space inside the distribution box from both sides. The front plate 51 can protect the middle part of the front of the two end plates 13. The two blocking strips 16 play a role in limiting the front plate 51, ensuring that the outer wall of the front plate 51 coincides with the middle edge of the edges of the two vertical plates 12, preventing the front plate 51 from being pushed into the interior of the distribution box and damaging the electronic components inside the distribution box. The vertical edges of the two side doors 41 are inclined planes, and the vertical edges of the two side doors 41 are in contact with the vertical edges of the two vertical plates 12, and a sealing effect can be achieved through the contact of the inclined planes. Compared with the traditional combination of two vertical right-angle edges, the inclined plane can have a larger contact surface, achieving a better sealing effect, reducing the amount of dust entering the distribution box through the gaps at the joints, and better protecting the electronic components inside the distribution box. The other vertical edges of the two side doors 41 can press on the two edges of the front plate 51 after closing, playing a role in limiting the two edges of the front plate 51 in the left-right direction and the front-back direction, ensuring that the front plate 51 cannot move after the two side doors 41 are closed, ensuring the stability of the two side doors 41 and the front plate 51 on the distribution box and the integrity of the space inside the distribution box, and ensuring the stable performance of the electronic components inside the distribution box under long-term use conditions.

[0028] Reference Figure 2 and 4 , a detailed description of an embodiment for fully separating high-heat-generating electronic components from other electronic components:

[0029] The partition frame 21 is an arc-shaped frame. Thus, a small space can be separated within the distribution box by the partition frame 21 and the end plates 13 on the upper and lower sides, such that the opening of the partition frame 21 faces the corresponding side door 41. Furthermore, the effect of guiding the air after heat exchange is achieved, preventing the air that has exchanged heat with the high-heat-generating electronic components within the space separated by the partition frame 21 from flowing to other electronic components, which may cause the working environment temperature of other electronic components to be too high and affect the service life of other electronic components.

[0030] Reference Figure 4 , a detailed description of an embodiment that makes full use of the space separated by the partition frame 21:

[0031] A plurality of suspension rods 22 are provided on the partition frame 21. Thus, high-heat-generating electronic components can be suspended on the suspension rods 22, fully installing and arranging a plurality of high-heat-generating electronic components, and fully utilizing the space separated by the partition frame 21;

[0032] To further optimize the installation method of high-heat-generating electronic components within the space separated by the partition frame 21, threads are provided in the middle of a plurality of suspension rods 22. Thus, the electronic components can be fixed by passing bolts through the installed electronic components and connecting them to the threads in the middle of the plurality of suspension rods 22.

[0033] Reference Figure 1 , 6 And 9, a detailed description of an embodiment in which the side door 41 fully encloses the space of the distribution box:

[0034] Two vertical surfaces are provided on each of the two side doors 41, and the two vertical surfaces on each side door 41 are right-angled vertical surfaces. One vertical surface of the side door 41 coincides with the vertical plate 12, and the other vertical surface of the side door 41 coincides with the front plate 51. The upper and lower end faces of each side door 41 are provided with face plates fixedly connected to the two vertical surfaces. Thus, when the two side doors 41 are closed, the space inside the distribution box is a rectangular space.

[0035] Reference Figure 8 , a detailed description of an embodiment of the front plate 51 that is stably installed:

[0036] Magnetic adsorption frames 57 corresponding to the two retaining strips 16 are provided on the front plate 51. Thus, when the front plate 51 is installed in contact with the two retaining strips 16, the two magnetic adsorption frames 57 are buckled on the two retaining strips 16, and the two magnetic adsorption frames 57 are magnetically adsorbed on the two retaining strips 16, thereby playing a fixing role. Then, the two side doors 41 are closed to achieve the enclosure of the space inside the distribution box by the two side doors 41 and the front plate 51.

[0037] Reference Figure 1 , 6 And 9, a detailed description of an embodiment for sealing the connection between the two side doors 41:

[0038] Sealing strips 43 are provided on the two side doors 41, so that the joints between the two side doors 41 and the front plate 51, the two vertical plates 12 and the two end plates 13 can be sealed, thereby realizing the sealing of the joints of the two side doors 41, preventing dust, water vapor, etc. from entering the distribution box through the joints of the two side doors 41 and affecting the long-term stable use of the electronic components in the distribution box.

[0039] Reference Figure 1 、 6 、7 and 9, a detailed description of the embodiment for limiting the opening of the two side doors 41 when the two side doors 41 are closed:

[0040] First handles 42 are provided on the two side doors 41, two second handles 56 corresponding to the two first handles 42 are provided on the front plate 51, two guide tubes 52 are provided on the front plate 51, a sliding rod 53 is slidably connected to each guide tube 52, and a plug rod 54 inserted into the first handle 42 and the second handle 56 is fixedly connected to each sliding rod 53, and a spring 55 is sleeved on each sliding rod 53.

[0041] Thus, when closing the two side doors 41, manually move the corresponding sliding rod 53 of the side door 41. While the sliding rod 53 slides, it drives the plug rod 54 to slide, and at the same time compresses the corresponding multiple springs 55, so that the plug rod 54 does not affect the closing of the side door 41. After the side door 41 is closed, release the sliding rod 53, and the spring 55 compressed by the force pushes the sliding rod 53 to drive the plug rod 54 to slide back into the first handle 42, realizing the restriction of the side door 41 and preventing the side door 41 from rotating and opening the space inside the distribution box. When it is necessary to open the side door 41, manually move the corresponding sliding rod 53 of the side door 41. While the sliding rod 53 slides, it drives the plug rod 54 to slide, and at the same time compresses the corresponding multiple springs 55, so that the plug rod 54 does not affect the opening of the side door 41. After the side door 41 is opened, release the sliding rod 53, and the spring 55 compressed by the force pushes the sliding rod 53 to drive the plug rod 54 to reset. After opening the two side doors 41, hold the second handle 56 by hand and remove the front plate 51 to realize the complete expansion of the space inside the distribution box.

[0042] Reference Figure 1 、 3 And 5, a detailed description of the embodiment for installing a fan to guide the air flow inside the distribution box to take away the heat inside the distribution box:

[0043] A first ventilation hole 17 is provided on one of the two vertical plates 12, a second ventilation hole 18 is provided on the upper end plate 13, protective covers 31 are correspondingly provided for both the first ventilation hole 17 and the second ventilation hole 18, a column sleeve 32 is slidably connected to each protective cover 31, and the two protective covers 31 are respectively fixedly connected to the corresponding vertical plate 12 and end plate 13. An arc-shaped opening is provided on the protective cover 31, and a filter paper is detachably connected to each protective cover 31.

[0044] Fans are installed on the first ventilation hole 17 and the second ventilation hole 18. The fan on the first ventilation hole 17 can guide the external air flow to blow into the interior of the distribution box, and flow over the electronic components from the front of the electrical installation rail installed on the hanging plate 14, so as to realize the rapid flow of air through the outflow of air, and then take away the heat dissipated by the electronic components; while the fan corresponding to the second ventilation hole 18 can guide the air in the upper part of the distribution box to flow into the space separated by the partition frame 21 through the second ventilation hole 18, and then flow out from the opening of the partition frame 21 to take away the heat of the high-heat-generating electronic components, and then flow out of the distribution box, so as to guide the heat dissipated by the electronic components in the distribution box to flow out of the distribution box quickly and realize the cooling of the electronic components. The protective cover 31 is barrel-shaped, and the arc-shaped opening on the side wall of the barrel-shaped protective cover 31 is used for the placement and installation of the fan. At the same time, it can prevent the external fluid from directly entering the interior of the distribution box along the axis direction of the protective cover 31 under the guidance of the fan blade. Under the guidance of the fan blade, the air first passes through the arc-shaped opening of the protective cover 31 and flows radially along the protective cover 31, and then enters the distribution box along the axis of the protective cover 31, so as to slow down the air flow speed, reduce the dust carried by the air from entering the distribution box, and give the electronic components a good use environment, thereby prolonging the service life of the electronic components and reducing the errors of the electronic components caused by dust accumulation and poor heat dissipation. A filter paper is glued to the outer wall of each protective cover 31, and the filter paper is attached to the arc-shaped opening of the protective cover 31 under the support of the bushing 32, so as to filter the air flowing through the arc-shaped opening through the filter paper and reduce the dust entering the distribution box.

[0045] Reference Figure 1 、 6 And 9, an embodiment of the air outflow in the distribution box is described in detail:

[0046] The partition frame 21 is arranged on one side of the two end plates 13. A plurality of air outlet holes 44 are arranged on the side door 41 close to the partition frame 21. A plurality of convex blocks are arranged on the side door 41, and each convex block is provided with a bushing 45. A filter paper covering the plurality of air outlet holes 44 is detachably connected to the plurality of bushings 45. The air in the distribution box flows out from the plurality of air outlet holes 44, so as to realize the stable circulation of the air in the distribution box. The plurality of air outlet holes 44 are correspondingly arranged with the opening of the partition frame 21 to ensure that the air flowing in the partition frame 21 directly flows out from the plurality of air outlet holes 44 after being guided by the partition frame 21, preventing the heat dissipated by the high-heat-generating electronic components from flowing to other electronic components, so as to fully reduce the environmental temperature in the distribution box and ensure the long-term stable operation of the electronic components. The plurality of bushings 45 can be clamped on the convex blocks after the filter paper is pressed on the convex blocks to fix the filter paper, so that the filter paper covers the plurality of air outlet holes 44, further filtering the channel for the internal and external circulation of the distribution box, reducing the dust entering the distribution box, and ensuring the working environment of the electronic components.
