Technical Field

[0001] The invention relates to the technical field of electrical equipment, in particular to a cable branch box capable of preventing rainwater from penetrating. Background Art

[0002] A cable branch box is an electrical device that transfers and branches cables. It is mainly used to divide a main cable into multiple branch cables to achieve power distribution and transmission. The cable branch box can be installed outdoors or indoors to connect, seal, insulate and protect the cables. It can improve the flexibility and reliability of the cable system, facilitate subsequent maintenance and management, and reduce the impact of cable failures on the entire power system to a certain extent. Cable branch boxes have different types and specifications to adapt to different application scenarios and cable configuration requirements.

[0003] During the use of the cable branch box, the internal electronic components need to be protected, and at the same time, the internal heat needs to be dissipated to prevent the internal temperature from rising and affecting the operation of the equipment. Therefore, a new design was made to address this situation. Summary of the invention

After external wind enters the interior of the box, the fiberboard is blown to sway appropriately with the wind. The temperature inside the box will rise when working. When the air enters the box and comes into contact with the internal temperature, water vapor is easily generated to form condensation. The fiberboard is made of plant fiber and has good water absorption, so as to achieve the effect of absorbing water vapor, prevent condensation, avoid corrosion of the equipment, reduce the service life and reliability of the equipment, avoid reducing the insulation performance, and increase the risk of leakage, short circuit and other faults. Fiber grooves are provided on both sides of the outside of the fiberboard. By providing the fiber grooves, the slotted design can enhance the stability and reliability of the overall structure to a certain extent and improve the service life of the equipment.

[0010] Preferably, the input mechanism includes an input baffle, which adopts an inclined design to shield the ventilation part of the box shell, prevent rainwater from entering and hinder insects. One side of the outside of the input baffle is fixedly connected to one side of the outside of the box shell, and a guide plate is fixedly connected to the lower side of the inner wall of the input baffle, and the guide plate guides the air. A connecting block is fixedly connected to one side of the inner wall of the input baffle close to the guide plate, and a cylindrical shaft is rotatably connected to one side of the outside of the connecting block. A filter plate is fixedly connected to the outside of the cylindrical shaft, and the guide plate guides the air. The filter plate adopts a combination design of multiple plates. When the air impacts the filter plate through the guide plate, the filter plate rotates, thereby achieving a uniform filtering effect, extending the service life of the equipment, and having a ventilation and heat dissipation effect. When there is a temperature difference between the inside of the box and the external environment, ventilation through the openings can promote air exchange, allowing hotter air to flow out of the box and cooler air to enter the box, thereby helping to reduce the temperature difference between the inside and outside, avoiding excessive thermal expansion and contraction of the equipment due to excessive temperature difference, reducing damage to the equipment structure and performance, and extending the life of the equipment. Square incisions are opened on both sides of the outside of the filter plate. The square incisions increase the contact area with impurities and improve the filtering effect.

[0011] Preferably, the protective mechanism includes a protective top plate, which serves to shield the top of the box from wind and rain, reduce corrosion of the box by the external environment, and prevent damage to the equipment by falling objects from high altitude.

By providing the arc-shaped groove, rainwater on the top can be guided to flow, rainwater can be prevented from being retained, and long-term corrosion to the equipment can be avoided, thereby extending the service life of the equipment. The arc-shaped groove adopts a streamlined design. When encountering strong winds, the wind resistance can be reduced, and the wind can flow through the box more smoothly, reducing the direct impact of the wind on the box, reducing the risk of the box being shaken, displaced or damaged by the strong wind, and reducing instability caused by wind.

A sliding block is fixedly connected to the side of the square plate close to the strip groove, and a sliding bracket is connected to the sliding block to slide in the strip groove of the square plate. By sliding, the shock absorption and buffering effect is achieved, the impact force is reduced, and the damage to the box body caused by falling objects from high altitude is reduced.

The pipe shell adopts a design with wide ends and a narrowed diameter in the middle. According to Bernoulli's principle, the pipe diameter is reduced, and the gas flow speed is faster at the reduced part, thereby achieving the effect of increasing the gas flow speed and improving the ventilation and heat dissipation effects. The composite shell supports the box structure and also serves as a lifting design to prevent rainwater from entering from the bottom, thereby protecting the equipment. The outside of the air vent is fixedly connected with an additional mechanism, and the inner wall of the pipe shell close to the air vent is fixedly connected with a cleaning mechanism.

[0014] Preferably, a fixing frame is fixedly connected to one side of the inner wall of the pipe shell, a spring rod is fixedly connected to one side of the outside of the fixing frame, and a barrel-shaped block is fixedly connected to the side of the spring rod away from the fixing frame. The fixing frame supports the spring rod, and the barrel-shaped block is designed with a wide outer end and a smaller inner end, which blocks debris and insects. A flow groove is provided on the outside of the barrel-shaped block, which guides the airflow and reduces the dust entry rate. A strip block is fixedly connected to the side of the inner wall of the pipe shell close to the flow groove. When a strong external airflow or a large water flow impacts the barrel block, the spring rod is compressed and presents a contracted state, and the flow groove of the barrel block and the strip block are closed, thereby blocking the entry of water. The water flow exceeds the depth of the barrel block, so the external pressure increases, which can make the sealing of the flow groove and the strip block better, thereby achieving a protective effect.

[0015] Preferably, the additional mechanism includes a connecting pipe. When the airflow is accelerated in the middle of the pipe shell, the connecting pipe is designed with wide ends and a narrowed diameter in the middle.

One side of the outside of the connecting pipe is fixedly connected to the outside of the air vent, and the outside of the connecting pipe is fixedly connected to a ring plate. The ring plate supports the connecting pipe, reduces the amplitude of the airflow, and maintains the stability of the structure.

[0016] Preferably, the cleaning mechanism includes a ring-shaped plate, the outside of the ring-shaped plate is fixedly connected to the inner wall of the pipe shell, the outside of the ring-shaped plate is rotatably connected to a rotating shaft, one side of the outside of the rotating shaft is fixedly connected to a paddle, the ring-shaped plate supports the rotating shaft, when the airflow impacts the paddle, the rotation of the paddle drives the friction plate to rotate, thereby scraping the inner wall of the equipment, so as to achieve the cleaning effect of the inner wall of the equipment, prevent dust accumulation and blockage, and affect the normal operation of the equipment, the side of the rotating shaft away from the paddle is fixedly connected to a connecting frame, the side of the outside of the connecting frame is fixedly connected to a friction plate, the outside of the friction plate is provided with a tooth mark groove, by providing the tooth mark groove, the friction effect is improved, the local concentrated stress is reduced to avoid the aggravated damage, the service life of the equipment is extended, the impurities are guided, the adsorption of impurities is reduced, and the further impact of debris on the friction surface and the scraping process is reduced.

Secondly, the arc-shaped groove adopts a streamlined design. When encountering strong winds, the wind resistance can be reduced, so that the wind can flow through the box more smoothly, reducing the direct impact of the wind on the box, reducing the risk of the box being shaken, displaced or damaged by strong winds, and reducing the instability caused by wind.

[0021] Fourth, the cable branch box that prevents rainwater from penetrating is designed with a composite structure. The pipe shell adopts ventilation on both sides to increase the probability of airflow entering. The pipe shell is designed with wide ends and a narrowed diameter in the middle. According to the Bernoulli principle, the pipe diameter is reduced, and the gas flow speed is faster at the narrowed part, thereby achieving the effect of increasing the gas flow speed and improving the ventilation and heat dissipation effect. The composite shell supports the box structure and also serves as a lifting design to prevent rainwater from entering the bottom and protect the equipment.

Secondly, the arc-shaped groove 22 adopts a streamlined design, which can achieve the effect of reducing wind resistance when encountering strong winds, so that the wind can flow through the box more smoothly, reduce the direct impact of the wind on the box, reduce the risk of the box being shaken, displaced or damaged by the strong wind, and reduce the instability caused by the wind.

[0040] A strip groove 27 is provided on one side of the outside of the square plate 25, and a friction strip 26 is fixedly connected inside the strip groove 27.

[0041] The third embodiment is based on the first and second embodiments. Figures 6 to 8 As shown, the composite mechanism 3 includes a composite shell 301, the top of the composite shell 301 is fixedly connected to the bottom of the box shell 101, the inner wall of the composite shell 301 is fixedly connected to the pipe shell 302, the middle of the outer part of the pipe shell 302 is provided with an air vent 303, the outer part of the air vent 303 is fixedly connected with an additional mechanism 309, and the inner wall of the pipe shell 302 is fixedly connected with a cleaning mechanism 310 on one side near the air vent 303.

Secondly, the composite shell 301 supports the box mechanism 1, and at the same time plays a lifting design to prevent rainwater from entering the bottom, thereby protecting the equipment.

[0042] A fixing frame 304 is fixedly connected to one side of the inner wall of the pipe shell 302, a spring rod 305 is fixedly connected to one side outside the fixing frame 304, a barrel-shaped block 306 is fixedly connected to the side of the spring rod 305 away from the fixing frame 304, a flow groove 307 is provided on the outside of the barrel-shaped block 306, and a bar-shaped block 308 is fixedly connected to one side of the inner wall of the pipe shell 302 close to the flow groove 307.

By providing the tooth mark groove 3106, the friction effect is improved, the local concentrated stress is reduced to avoid further damage, and the service life of the equipment is extended. It plays a guiding role on impurities, reduces the adsorption of impurities, and reduces the further impact of debris on the friction surface and the scraping process.

[0045] When in use, the staff opens the box door 102, installs the internal electronic components, and then closes the box shell 101, and stores and protects the electronic components through the box mechanism 1. Secondly, the cable branch box is mostly installed outdoors and needs to cope with the harsh outdoor environment. While the box mechanism 1 is closed, the internal heat dissipation is required to prevent the internal components from operating at too high a temperature for a long time.
