Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable branch box technology, and in particular to a novel cable branch box. Background Technology
[0002] A cable branch box is a device used in power systems to branch and connect cables. As a cable branch, the main function of the cable branch box is to split or transfer cables.
[0003] In the prior art, patent publication number CN220358761U discloses a novel cable branch box, including a box body with a door on the front. This novel cable branch box has cooling water tanks symmetrically arranged on both sides of the box body, and heat dissipation holes on the back of the box body. A heat exchange pipe is installed inside the cooling water tank, and a small fan is installed at the top of the heat exchange pipe. A duct is connected between the output end of the small fan and the heat exchange pipe, and a flexible hose is connected to the other end of the heat exchange pipe. A movable pipe is connected to one end of the flexible hose, and an inverted bucket-shaped nozzle is installed at one end of the movable pipe inside the box body. The small fan can introduce outside air into the heat exchange pipe inside the cooling water tank. The air exchanges heat with the cooling water in the cooling water tank as it flows through the heat exchange pipe. The cooled air is then sprayed out through the inverted bucket-shaped nozzle to cool the inside of the box body, thereby ensuring the normal operation of the electrical components inside the cable branch box.
[0004] Although the aforementioned new type of cable branch box can achieve the effect of heat dissipation inside the branch box through the inverted bucket-shaped nozzle and cooling water tank, it still has the following shortcomings in practical applications: when hot and humid air enters the cool box, it cools down to the dew point temperature, and water vapor condenses into water droplets on the metal box wall, cable surface or insulation components. The water inside the box is difficult to drain to the outside, which makes it very easy for water to accumulate inside the box. Utility Model Content

Example 1
[0017] like Figure 1-4 As shown, the present invention proposes a novel cable branch box, comprising a box body 1, a door 11 hinged to the front of the box body 1, an observation window 12 fixedly fitted on the inner ring of the front of the door 11, an installation bracket 13 fixedly installed inside the box body 1, an inlet fan 4 and an exhaust fan 5 fixedly fitted on the inner ring of the left and right walls of the box body 1 respectively, a filter assembly 3 fixedly installed on both outer walls of the box body 1, corresponding to the inlet fan 4 and the exhaust fan 5 respectively, and a drainage assembly 2 provided on the bottom wall of the box body 1.
[0018] In this embodiment: the drainage component 2 includes a water collection trough 21 formed on the inner wall of the bottom of the housing 1. Multiple guide channels 22 are evenly formed on the inner wall of the bottom of the housing 1, and all guide channels 22 are connected to the water collection trough 21. Through this arrangement, the multiple guide channels 22 on the inner wall of the bottom of the housing are radially distributed with the water collection trough 21 as the center, guiding condensate or infiltrated rainwater to the water collection trough 21 in a directional manner, preventing water from accumulating locally at the bottom of the housing, preventing equipment corrosion or short circuits, and improving drainage efficiency. A grille 23 is snapped onto the top of the water collection trough 21. Through this arrangement, the grille 23, made of corrosion-resistant metal mesh or plastic grating, covers the inlet of the water collection trough 21. The snap-on design facilitates... The system is disassembled and cleaned to prevent cable joint debris, insects, and other debris from entering the drain pipe and causing blockages, while allowing water to flow quickly. An S-shaped water-blocking pipe 24 is fixedly inserted into the bottom of the water collection tank 21. The bottom end of the S-shaped water-blocking pipe 24 penetrates the bottom wall of the tank 1 and extends to the bottom of the tank 1. A one-way valve 25 is fixedly installed on its outer perimeter. Through this setting, the S-shaped curved pipe forms a water seal structure. The bottom of the pipe penetrates the tank and extends to the outside. The S-shaped pipe uses a water seal to prevent external humid air, dust, and insects from flowing back into the tank. The one-way valve 25 is installed at the end of the pipe, allowing liquid inside the tank to flow out in one direction only, preventing rainwater backflow or foreign object intrusion, and ensuring the airtightness of the tank during drainage. Example 2
[0019] like Figure 1-4As shown, this utility model proposes a novel cable branch box. Compared with Embodiment 1, this embodiment further includes a filter assembly 3, which includes a filter frame 31 fixedly installed on the side wall of the box body 1. A filter screen 32 is fixedly sleeved on the inner ring of the side of the filter frame 31. Through this arrangement, the filter screen 32 blocks external particles such as willow catkins and dust when the inlet fan 4 and the exhaust fan 5 are working, keeping the air inside the box clean. Limiting grooves 33 are opened on both sides of the front of the filter frame 31. A sliding plate 34 is slidably installed on the limiting grooves 33. A cleaning brush 35 is fixedly installed on the side of the sliding plate 34 near the filter screen 32, and the cleaning brush 35 abuts against the filter screen 32. A handle 36 is fixedly installed on the side of plate 34 away from cleaning brush 35. With this setting, the limiting groove 33 guides the slide plate 34 to slide vertically. The cleaning brush 35 is made of nylon bristles and is in close contact with the filter screen 32. The handle 36 is exposed on the front of the filter frame for easy manual operation. By pulling the handle 36 back and forth, the cleaning brush 35 is driven to scrape off the dust accumulated on the filter screen 32. Maintenance can be carried out without disassembly, ensuring ventilation efficiency. A support frame 6 is fixedly installed on the inner side wall of the box 1. A dehumidification box 7 is placed inside the support frame 6. With this setting, the dehumidification box 7 absorbs the moisture in the air inside the box 1, preventing excessive humidity inside the box from causing condensation or oxidation of components.
[0020] Working principle: Condensate or seepage liquid generated inside the chamber flows into the water collection tank 21 through the bottom guide channel 22. After being intercepted by the grille 23, it flows into the S-shaped water baffle pipe 24. The water seal structure prevents external moisture from flowing back in, and the one-way valve 25 drains the water in one direction. The intake fan 4 and exhaust fan 5 drive the air circulation. The external airflow enters the chamber after being purified by the filter screen 32. The dehumidification box 7 actively absorbs the moisture in the air inside the chamber 1, while the dust accumulated on the filter screen 32 can be manually removed by the cleaning brush 35 driven by the sliding plate 34. This achieves multiple protections of moisture prevention, drainage, dust prevention and continuous dehumidification, ensuring the stable operation of the equipment.
[0021] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
