Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of protection of the present application.

[0020] Embodiment one: the embodiment promotes to solve the problems that when the heat of multiple cables accumulates together, there are potential safety hazards, and the cables and the cables block each other, only the heat dissipation fan is easily blocked by the side-by-side cables, resulting in weak heat dissipation efficiency, and if multiple direction heat dissipation fans are arranged, the heat dissipation air flow is easily interfered, and the heat dissipation efficiency is poor. Please refer to Figure 1 Figure 8 An energy-saving and environment-friendly low-voltage cable branch box, comprising a cable branch box body 1 and a junction box 11 fixedly installed on the cable branch box body 1, an electric telescopic rod 16 fixedly installed on the outer wall of the junction box 11, a first moving frame 17 fixedly connected to the output end of the electric telescopic rod 16, the first moving frame 17 moving with the output end of the electric telescopic rod 16 after the electric telescopic rod 16 is started, the first moving frame 17 moving synchronously with the first guide rod 21 on the outer wall, the outer wall of the first moving frame 17 being fixedly connected with a plurality of first guide rods 21, one end of the first guide rod 21 being fixedly connected with a first sliding block 22, the outer wall of the first sliding block 22 being slidably sleeved with a second moving frame 18, the inner wall of the second moving frame 18 being fixedly connected with a second guide rod 25, the outer wall of the second guide rod 25 being slidably sleeved with a second sliding block 26, and the inner wall of the second sliding block 26 being slidably connected with a cable 20.

[0021] The inner wall of the junction box 11 is fixedly installed with a junction seat 19, and the cable 20 is fixedly installed on the junction seat 19; the junction box 11 is fixedly installed with a heat dissipation fan 12, and the blowing end of the heat dissipation fan 12 is fixedly installed with a dust screen 13.

[0022] The second guide rod 25 is sleeved with two second return springs 27, one end of the second return spring 27 being fixedly connected with the inner wall of the second moving frame 18, and the other end of the second return spring 27 being fixedly connected with the outer wall of the second sliding block 26.

[0023] The outer wall of the second sliding block 26 is fixedly connected with a second abutting block 28, and the second abutting block 28 is provided in the form of a spherical block.

[0024] The inner wall of the second moving frame 18 is slidably connected with a third guide rod 29, the third guide rod 29 is sleeved with a third return spring 30, one end of the third return spring 30 is fixedly connected with the outer wall of the second moving frame 18, and the other end of the third return spring 30 is fixedly connected with a third abutting block 31.

[0025] ​Two abutting inclined surfaces 32 are formed on the third abutting block 31, and one end of the third guide rod 29 is fixedly connected to the outer wall of the third abutting block 31. With the continuous upward movement of the third abutting block 31, the third abutting block 31 will bear upward force with the entire second moving frame 18, and the second moving frame 18 will slide along the outer wall of the first sliding block 22 with the sliding groove 23, and gradually stretch the first return spring 24. At this time, the cable 20 is pressed and deformed in part upward, and the cable 20 bent and deformed upward can make the airflow blown to it blocked and diffuse in more directions.

[0026] The outer wall of the third abutting block 31 is fixedly connected with the fourth guide rod 33, and one end of the fourth guide rod 33 is rotatably installed with the ball 34.

[0027] The inner wall of the junction box 11 is fixedly connected with a plurality of fixed plates 14, the outer wall of the fixed plate 14 is fixedly connected with a plurality of first abutting blocks 15, the first abutting block 15 is provided in a spherical shape, and when the plurality of second sliding blocks 26 move, a plurality of cable lines 20 from top to bottom are intermittently bent and deformed at different time points, so that when the upper heat dissipation fan 12 blows from top to bottom, it can be evenly blown on the surface of the plurality of cable lines 20. The cable lines 20 originally overlapped are no longer in an overlapped state at the same time point, so that the blowing and heat dissipation efficiency is greatly improved.

[0028] The outer wall of the cable branch box body 1 is hingedly installed with the hinged door 6, and the outer wall of the cable branch box body 1 is provided with a plurality of ventilation grooves 5. The cable branch box body 1 is fixedly connected with the inclined roof 3, the outer wall of the cable branch box body 1 is fixedly installed with the door lock 2, and the inner wall of the cable branch box body 1 is fixedly installed with the main circuit breaker 7. The inner wall of the cable branch box body 1 is fixedly installed with the mounting vertical rack 10, a plurality of branch circuit breakers 9 are fixedly installed on the mounting vertical rack 10, the branch circuit breaker 9 is electrically connected with the main circuit breaker 7, and a plurality of copper bars 8 are fixedly installed on the branch circuit breaker 9.

[0029] In this embodiment: when using the energy-saving and environment-friendly low-voltage cable branch box, the hinged door 6 can be opened for maintenance and cable connection operation. The main circuit breaker 7 can control the on-off state of the entire branch box, and then the plurality of branch circuit breakers 9 can control the on-off of the power supply of the plurality of branch devices. The outer side of the cable branch box body 1 is provided with a plurality of ventilation grooves 5, which can increase the heat dissipation efficiency.

[0030] When using the cable branch box, first, the external main cable needs to be connected to the terminal block 19, and during the connection process, the cable line 20 needs to pass through the plurality of second sliding blocks 26. After the cable line 20 is connected, in order to keep the temperature in the junction box 11 normal when the cable branch box main body 1 is working normally, two cooling fans 12 need to be started. After the two cooling fans 12 are started, external air is drawn in and blown into the junction box 11. The external air is filtered by the dust screen 13 before entering the junction box 11 to prevent pollution of the inside of the junction box 11.

[0031] With the start of the cooling fan 12, the outer wall of the plurality of cable lines 20 is blown, the heat around the cable line 20 is taken away, and finally transferred to the outside for heat exchange.

[0032] The electric telescopic rod 16 can be started, and the first moving frame 17 moves with the output end of the electric telescopic rod 16. When the first moving frame 17 moves, the first guide rod 21 on the outer wall moves synchronously. The movement of the first guide rod 21 moves the second moving frame 18 synchronously. After the second moving frame 18 moves, the two second sliding blocks 26 move synchronously. The inner wall of the second sliding block 26 can be scraped along the outer wall of the cable line 20 to remove dust and attached impurities on the outer wall of the cable line 20, preventing impurities from adhering to the cable line 20 to cause poor heat dissipation.

[0033] With the movement of the second moving frame 18, the third abutting block 31 moves synchronously, so that the fourth guide rod 33 on the outer wall of the third abutting block 31 moves. When the fourth guide rod 33 moves, the ball 34 moves synchronously. In the movement track, the ball 34 will abut against the outer wall of the first abutting block 15. The abutment causes the ball 34, the fourth guide rod 33 and the third abutting block 31 to move upward under stress, causing the abutment slope 32 on the outer wall of the third abutting block 31 to abut against the second abutting block 28. The abutment causes the second abutting block 28 to move away from each other under stress, and the two second sliding blocks 26 move away from each other along the guide of the second guide rod 25. During this process, the second sliding block 26 will extrude the second return spring 27, so that the second return spring 27 is gradually compressed and tightened.

[0034] When the two second sliding blocks 26 move away from each other, the two second sliding blocks 26 bend the cable line 20 on the inner wall of each second sliding block 26 transversely, causing the cable line 20 to bend and deform. It should be noted that the cable line 20 is arranged in multiple rows from top to bottom, and the first abutting block 15 corresponding to the multiple rows of cable lines 20 is arranged at different degrees of compactness, so that the multiple second sliding blocks 26 bend the cable line 20 at different time points, causing the multiple second sliding blocks 26 to move, so that the multiple cable lines 20 from top to bottom are intermittently bent and deformed at different time points. When the upper cooling fan 12 blows from top to bottom, it can be evenly blown on the surface of the multiple cable lines 20. The originally overlapping cable lines 20 are no longer in an overlapping state at the same time point, so that the blowing and cooling efficiency is greatly improved.

[0035] Embodiment two: this embodiment is made on the basis of embodiment one, specifically, please refer to Figure 1 - Figure 8 The second moving frame 18 is provided with a sliding groove 23, the first sliding block 22 is slidably connected to the inner wall of the sliding groove 23, and the inner wall of the sliding groove 23 is fixedly connected with two first return springs 24, one end of the first return spring 24 is fixedly connected with the outer wall of the first sliding block 22.

[0036] In this embodiment: after the rolling ball 34 collides with the surface of the first resisting block 15, when the third resisting block 31 moves upward to a certain height, at this time, the third guide rod 29 will slide to the end along the inner wall of the second moving frame 18, at this time, with the continuous upward movement of the third resisting block 31, the third resisting block 31 will bear upward force with the whole second moving frame 18, the second moving frame 18 will slide along the outer wall of the first sliding block 22 with the sliding groove 23, and gradually stretch the first return spring 24, at this time, the cable 20 is pressed and deformed upward, the cable 20 which is deformed upward can make the airflow blown to it blocked and diffuse in more directions, so that the heat dissipation efficiency in the junction box 11 is increased.
