Technical Field

[0001] This utility model relates to the field of outdoor cable branch box technology, and more specifically to an outdoor cable branch box that prevents rainwater penetration. Background Technology

[0002] Outdoor cable distribution boxes are important equipment used for cable connection and distribution in power systems. They are usually installed outdoors and need to be exposed to harsh conditions such as rain for a long time. In order to ensure heat dissipation, existing outdoor cable distribution boxes often need to have a lot of ventilation holes. However, this will increase the risk of rainwater infiltration, making it impossible to balance heat dissipation efficiency and waterproof performance, thus affecting the normal operation of the equipment. In view of the above-mentioned problems in the existing technology, the present invention provides an outdoor cable branch box that prevents rainwater penetration. By installing a guide channel, optimizing the heat dissipation hole structure, and cooperating with the automatic water baffle, the contradiction between waterproofing and heat dissipation in the existing technology is solved, while also improving the reliability and service life of the device.

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The outdoor cable branch box for preventing rainwater penetration involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Reference Figure 1-7 This utility model provides an outdoor cable branch box that prevents rainwater penetration, including a branch box assembly 1, a waterproof component 2 installed inside the branch box assembly 1, and a ventilation component 3 connected to the top of the branch box assembly 1. Reference Figure 1 , Figure 2 and Figure 3The branch box assembly 1 includes a box body 101, a box door 102, a handle 103, a top cover 104, and a flow guide 105. The box door 102 is detachably installed on one side of the box body 101, and inclined heat dissipation holes are evenly distributed on both sides of the box body 101. Double-layer sealing strips are evenly distributed at the connection between the box door 102 and the box body 101, and the handle 103 is fixedly installed on the side of the box door 102 away from the box body 101. The top cover 104 is movably connected to the top of the box body 101. Furthermore, the top cover 104 has a hollow structure inside, and the outer wall of the top cover 104 is detachably equipped with a guide channel 105. The purpose is to guide rainwater to the sides of the box 101 through the guide channel 105 on the side wall of the top cover 104, so as to prevent rainwater from flowing through the connection between the box 101 and the door 102 or into the heat dissipation holes on both sides. In addition, there are inclined heat dissipation holes on both sides of the box 101, which use gravity to block rainwater from entering, reduce the risk of water seepage inside the box, and improve the waterproof performance of the box 101. Reference Figure 1 , Figure 4 and Figure 6 The waterproof component 2 includes a reinforcing rib 201, a base 202, a hydraulic rod 203, a connector 204, a water baffle 205, and a rain sensor 206. The reinforcing rib 201 is fixedly installed around the perimeter of the inner cavity of the housing 101 and is symmetrically distributed. A groove is designed on the side of the reinforcing rib 201 closest to the housing 101. The base 202 is fixedly installed on the top of the housing 101, and a hydraulic rod 203 is movably installed on the bottom of the base 202. A connector 204 is fixedly connected to the bottom of the hydraulic rod 203. The rain sensor 206 is detachably installed on the top of the top cover 104 and is movably connected to the top of the water baffle 205. The purpose is to set up the overall cooperation of the waterproof component 2 so that when rain is detected, the hydraulic rod 203 will push the water baffle 205 to block the heat dissipation holes on both sides of the housing 101, further preventing rainwater from flowing in through the heat dissipation holes. At the same time, integrating the water baffle 205 into the housing 101 helps to extend its overall service life. While enhancing the waterproof performance, it also helps to save on operating costs. Reference Figure 5 and Figure 7The ventilation assembly 3 includes a protective shell 301, a motor 302, a transmission rod 303, a sealing ring 304, a rotating shaft 305, rotating blades 306, and a temperature and humidity sensor 307. The protective shell 301 is movably placed inside the cavity of the top cover 104, and the motor 302 is movably installed inside the protective shell 301. The bottom of the motor 302 is movably connected to the transmission rod 303. The transmission rod 303 passes through an opening at the top of the housing 101 and is rotatably connected to the rotating shaft 305. The sealing ring 304 is detachably installed on the contact surface between the transmission rod 303 and the housing 101. The rotating shaft 305... The outer wall of the enclosure 101 is fixedly equipped with circumferentially distributed rotating blades 306. The temperature and humidity sensor 307 is detachably installed on the side wall of the enclosure 101 near the top. The purpose of installing the temperature and humidity sensor 307 is to monitor the temperature and humidity environment inside the enclosure 101 in real time. When the humidity is detected to be too high, the motor 302 is started to drive the temperature and humidity sensor 307 to expel the moisture out of the enclosure. When the temperature is too high, the heat dissipation effect can be further increased to keep the inside of the enclosure dry, prevent condensation and moisture from damaging the equipment inside the enclosure, reduce manual intervention, and improve the reliability of the device.

[0024] The working principle of this utility model is as follows: First, place the device in an outdoor working environment, ensuring the bottom of the housing 101 is stable. Connect the cable and check that the internal components are securely installed. Confirm that the double-layer sealing strip at the door seam is in a compressed state. Connect the rain sensor 206 and the temperature and humidity sensor 307 to the external power supply. Under normal weather conditions, the device operates normally. The heat generated inside can be treated by air convection through the heat dissipation holes, ensuring good heat dissipation efficiency. In extreme weather conditions, rainwater will preferentially fall onto the top cover 104 area. The rainwater can be guided to the housing 101 through the guide groove 105 on the side wall of the top cover 104. On both sides, since the length and width of the top cover 104 are larger than those of the box body 101, the guide channel 105 can further prevent rainwater from flowing through the seam between the box body 101 and the door 102, thus affecting the sealing effect. At the same time, the rain sensor 206 will judge based on the detected rainfall. If the rainfall exceeds the preset threshold, it will drive the hydraulic rod 203 to extend and push the baffle 205 downward along the groove of the reinforcing rib 201 until the baffle 205 completely covers the heat dissipation hole, and then stop the hydraulic rod 203. At this time, even if rainwater enters the heat dissipation hole due to other factors, it will be blocked by the baffle. 205 blocks the water flow, preventing it from entering the enclosure 101 and affecting the equipment. After the rain stops, the rain sensor 206 drives the hydraulic rod 203 to retract according to a preset value, causing the baffle 205 to rise along the groove of the reinforcing rib 201, removing the obstruction of the heat dissipation holes and restoring the initial working state. Since the waterproof component 2 is integrated inside the enclosure 101, it not only ensures waterproof performance but also effectively extends service life and reduces operating costs. After rainfall, the environment often becomes humid and hot. At this time, when the temperature and humidity sensor 307 near the top side wall of the enclosure 101 detects that the humidity is too high, exceeding the preset humidity level... When the threshold is reached, the motor 302 will be driven to run. The motor 302 will drive the transmission rod 303, which is movably connected to it, to rotate through the coupling. Since the transmission rod 303 passes through the opening at the top of the housing 101 and is movably connected to the rotating shaft 305, it will drive the rotating shaft 305 to rotate together. Under the rotation of the rotating shaft 305, the rotating blade 306, which is fixedly installed on the outer wall of the rotating shaft 305, will also rotate with the rotating shaft 305, thereby expelling moisture from the housing and keeping the inside of the housing dry. When the detected temperature is too high, the same principle applies. By accelerating the rotation of the rotating blade 306, the heat dissipation effect is enhanced, ensuring that the temperature inside the housing is within a safe range.
