Description

Technical Field

[0001] This utility model relates to the field of distribution box technology, specifically a distribution box with wind and sand protection function. Background Technology

[0002] Distribution boxes are key equipment in power systems used to distribute, control, and protect electrical energy. They are widely used in industrial, commercial, civil buildings, and public facilities. By integrating components such as circuit breakers, switches, protection devices, and metering instruments, they achieve reasonable distribution, safe control, and fault protection of electrical energy, ensuring the stable operation of the power system.

[0003] According to patent number 201920114758.6 published on the China Patent Website, this application relates to an outdoor power distribution box, including a power distribution box body, a monitoring device, an alarm device, and a dynamic adjustment device. The monitoring device is installed on the power distribution box body and is used to monitor the operating status of the outdoor power distribution box. The alarm device is installed on the power distribution box body and is electrically and signal-connected to the monitoring device, used to provide alarm prompts based on the operating status of the outdoor power distribution box. The dynamic adjustment device is installed on the power distribution box body and is used to adjust the three-phase current in real time. The outdoor power distribution box provided by this application can solve the problems of traditional solutions. The distribution cabinet suffers from poor automatic control capabilities, unstable operation, and inconvenient maintenance. However, the open heat dissipation vent design of this distribution box makes its structural defects particularly prominent in windy and sandy environments. Dust particles in the air can directly penetrate into the cabinet with the airflow, causing dust to accumulate on the surface of components. According to actual measurements, for every 0.5mm increase in dust thickness, the heat dissipation efficiency of the components decreases by 15%-20%. At the same time, it triggers electrostatic adsorption effects, accelerating the oxidation and corrosion of metal contacts. This design defect requires maintenance personnel to perform deep cleaning every 30-45 days, reducing the practicality of the distribution box.

[0004] Therefore, the distribution box needs to be improved to prevent sand and gravel in the air from entering the distribution box through the heat dissipation vents and affecting the components inside the distribution box. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 4 As shown, the present invention provides a power distribution box with wind and sand protection function, including power distribution box 1;

[0023] The front and rear sides of the distribution box 1 are equipped with protective frames 2. The inside of the protective frame 2 is provided with ventilation openings 3. The inner side of the protective frame 2 is in contact with the surface of the distribution box 1. The two sides of the protective frame 2 are fixedly connected with clamping plates 4. The inner side of the clamping plates 4 is slidably connected to the surface of the distribution box 1. The surface of the clamping plates 4 is covered with mounting sleeves 5. The inner side of the mounting sleeves 5 is fixedly connected to the surface of the distribution box 1. The outer side of the protective frame 2 is provided with a mounting groove 6. The inside of the mounting groove 6 is provided with a mounting frame 7. The surface of the mounting frame 7 is in contact with the inner wall of the mounting groove 6. The inside of the mounting frame 7 is fixedly connected with a filter screen 8.

[0024] refer to Figure 4The front and rear sides of the protective frame 2 are fixedly connected to the transmission box 9. The inside of the transmission box 9 is slidably connected to the push plate 10. The surface of the push plate 10 is slidably connected to the inner wall of the transmission box 9. The outside of the push plate 10 is fixedly connected to the movable block 11. The inside of the movable block 11 is movably connected to the connecting block 12 through the pin. The outside of the connecting block 12 is fixedly connected to the connecting plate 13. The outside of the connecting plate 13 extends to the outside of the transmission box 9 and is fixedly connected to the pressure plate 14. The end of the pressure plate 14 away from the connecting plate 13 extends to the surface of the mounting frame 7 and contacts the surface of the mounting frame 7.

[0025] As a technical optimization of this utility model, by setting up a transmission box 9, a push plate 10, a movable block 11, a connecting block 12, a connecting plate 13 and a clamping plate 4, the mounting frame 7 can be limited, thus preventing the mounting frame 7 from automatically falling off during use.

[0026] refer to Figure 2 Pull plates 15 are fixedly connected to the top and bottom of the mounting frame 7. The end of the pull plate 15 away from the mounting frame 7 passes through the protective frame 2 and contacts the inner wall of the protective frame 2.

[0027] As a technical optimization of this utility model, by setting the pull plate 15, it is easy for the user to pull the mounting frame 7 outward, and prevent the mounting frame 7 from being difficult to remove after it is stuck inside the mounting groove 6.

[0028] refer to Figure 2 A pull ring 16 is provided on the outside of the transmission box 9, and the inside of the pull ring 16 is fixedly connected to the outside of the pressure plate 14.

[0029] As a technical optimization of this utility model, by setting the pull ring 16, it is easy for the user to pull the pressure plate 14 outward, and prevent the user from directly pulling the pressure plate 14 and causing slippage.

[0030] refer to Figure 4 The transmission box 9 has two guide rods 17 fixedly connected horizontally inside. The guide rods 17 pass through the push plate 10 and are slidably connected to the push plate 10. The surface of the guide rods 17 is fitted with a spring return device 18. The inner side of the spring return device 18 is fixedly connected to the outer side of the push plate 10, and the outer side of the spring return device 18 is fixedly connected to the inner wall of the transmission box 9.

[0031] As a technical optimization of this utility model, by setting the guide rod 17 and the spring return device 18, the push plate 10 can move inward automatically, and the pressure plate 14 can be pressed against the surface of the mounting frame 7.

[0032] refer to Figure 3 Bolts 19 are provided on the surface of the transmission box 9. The inner side of the bolts 19 penetrates the connecting plate 13 and extends into the interior of the transmission box 9. The bolts 19 are threadedly connected to the connecting plate 13 and the transmission box 9.

[0033] As a technical optimization of this utility model, by setting bolt 19, the connecting plate 13 can be limited to prevent it from being pulled by people at will.

[0034] The working principle and usage process of this utility model are as follows: In use, the protective frame 2 is first inserted into the mounting sleeve 5 by the clamping plates 4 on both sides to limit the protective frame 2. After the limit is completed, the mounting frame 7 and the filter screen 8 are inserted into the mounting groove 6 by the pull plate 15. After insertion, the connecting plate 13 and the pressure plate 14 are flipped towards the center by the movable block 11. After flipping to 90 degrees, the spring force of the spring spring device 18 drives the push plate 10 to move inward. The push plate 10 drives the movable block 11 and the connecting block 12 to move inward. The connecting block 12 drives the connecting plate 13 and the pressure plate 14 to move inward. After moving to the limit position, the pressure plate 14 presses against the surface of the mounting frame 7 to limit the mounting frame 7. The air inside the distribution box 1 is discharged from the bottom of the protective frame 2 through the ventilation port 3. The external air enters the interior of the distribution box 1 after being filtered by the filter screen 8. Finally, the above operation is reversed to remove the mounting frame 7 and the filter screen 8, and the filter screen 8 can be replaced.

[0035] In summary, this wind and sand resistant distribution box, through the installation of a protective frame 2, ventilation opening 3, mounting groove 6, mounting frame 7, and filter screen 8, can protect the heat dissipation mesh opening, preventing sand and gravel from directly entering the interior of the distribution box 1 and affecting its normal operation. Furthermore, by incorporating a push plate 10, movable block 11, connecting block 12, connecting plate 13, and pressure plate 14, the mounting frame 7 can be limited, preventing it from detaching during use. This provides excellent wind and sand protection and addresses the structural defects of the open-style heat dissipation vent design, which are particularly pronounced in windy and sandy environments. In such environments, dust particles can directly penetrate the box with the airflow, causing dust to accumulate on the surface of components. Actual measurements show that for every 0.5mm increase in dust thickness, the heat dissipation efficiency of components decreases by 15%-20%. Simultaneously, it triggers electrostatic adsorption, accelerating the oxidation and corrosion of metal contacts. This design flaw necessitates deep cleaning by maintenance personnel every 30-45 days, reducing the practicality of the distribution box.
