Description

Technical Field

[0001] The invention belongs to the technical field of cable branch boxes, in particular to a cable branch box capable of preventing rainwater from entering. Background Art

[0002] The cable branch box is only used as a cable branch. The main function of the cable branch box is to branch or transfer the cable. It mainly plays the role of cable branching and cable transfer. With the development of the cableization process of the distribution network, when the independent load with small capacity is distributed more concentratedly, the cable branch box can be used to connect multiple branches of the cable, because the branch box cannot directly operate each line.

[0003] At present, most cable branch boxes include a box body and a box door hinged on one side of the box body. When the staff needs to inspect and maintain the electrical components inside the box body, they only need to open the box door. When the box door is in a closed state on one side of the box body, there will be a gap of a certain size between the box door and the box body. When the rainy season comes, rainwater from the outside will penetrate into the box body along the gap, causing the electrical components inside the box to be damaged by moisture. Based on this, the prior art usually sets up a rainproof awning on the top of the box body, and guides the rainwater acting on the box body to the ground through the rainproof awning. However, the rainproof awning can only play a diversion effect for vertically falling rainwater or slightly inclined rainwater. However, with the increase of wind force, the inclination angle of rainwater becomes larger, and rainwater with a large angle of inclination will pass over the rainproof awning and directly act on the side wall of the box body, thereby penetrating into the box body from the gap between the box door and the box body. Therefore, the existing cable branch box has a poor anti-intrusion effect for rainwater, and it is urgently needed to be improved. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the embodiments of the present invention is to provide a cable branch box that prevents rainwater from entering.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: A cable branch box for preventing rainwater from entering comprises a box body, a box door, a flexible sealing component, a piston component and a rotary drive component. The box door is hingedly arranged on one side of the box body. The flexible sealing assembly is mounted on the inner wall of the box body, the piston assembly is disposed on the inner wall of the box door and is in communication with the flexible sealing assembly, one end of the rotary drive assembly extends to the outer side of the box door, and the other end extends to the inner side of the box door. When the box door is closed on one side of the box door, the rotary drive assembly drives the piston assembly to move to pressurize air into the flexible sealing assembly, so that the flexible sealing assembly expands and thereby seals the gap between the box door and the box body.

[0006] As a further improvement of the present invention: the flexible sealing assembly comprises a rectangular frame and a flexible layer, The rectangular frame is fixedly arranged at a position inside the box body close to the box door, a rectangular air passage is opened on a side of the rectangular frame facing the box door, and the flexible layer is embedded in the rectangular air passage.

[0007] As a further improvement of the present invention: the rotary drive assembly includes a rotating wheel, an arc block and a rotating shaft, The rotating shaft passes through the box door and rotates with the box door, the rotating wheel is fixedly arranged on the shaft body of the rotating shaft located on the inner side of the box door, and the arc block is fixedly installed on the circumferential side wall of the rotating wheel. The piston assembly includes a flexible air pipe, a piston cylinder and a piston rod. The piston cylinder is fixedly mounted on the inner wall of the box door, one end of the piston rod extends into the interior of the piston cylinder and cooperates with the piston cylinder telescopically, the other end extends to the outside of the piston cylinder and abuts against the circumferential side wall of the rotating wheel, one end of the flexible air pipe is connected to the inner cavity of the piston cylinder, and the other end is connected to the rectangular airway in the rectangular frame.

[0008] As a further improvement of the present invention: a hand wheel is fixedly arranged on the shaft body of the rotating shaft located on the outer side of the box door.

[0009] As a further improvement of the present invention: an elastic member is further provided inside the piston cylinder, and the elastic member is used to provide elastic support for the piston rod.

[0010] As a further improvement of the present invention: a limiting groove is provided on the inner wall of the box body, a limiting rod is fixedly provided on the shaft body of the rotating shaft located on the inner side of the box door, and the limiting rod is perpendicular to the rotating shaft.

[0011] As a further improvement of the present invention: the limiting groove is provided on a side of the rectangular frame away from the box door.

[0012] As a further improvement of the present invention: a shift lever is fixedly arranged on the inner wall of the box door.

[0013] Compared with the prior art, the present invention has the following beneficial effects: In the embodiment of the present invention, when the cable branch box is in normal operation, the box door is in a closed state on one side of the box body. At this time, the rotating drive assembly drives the piston assembly to move, thereby pressurizing air into the flexible sealing assembly. When the flexible sealing assembly is filled with air, it can expand, thereby sealing the gap between the box door and the box body to prevent rainwater from penetrating into the box body through the gap between the box door and the box body, thereby preventing the electrical components inside the box from being damaged by moisture. Compared with the prior art, the gap between the box door and the box body can be effectively sealed, thereby preventing external rainwater from penetrating into the box body through the gap between the box door and the box body, thereby improving the moisture-proof protection effect of the electrical components inside the box.

[0019] See also Figure 1 The present embodiment provides a cable branch box for preventing rainwater from intruding, including a box body 10, a box door 20, a flexible sealing assembly 30, a piston assembly 40 and a rotary drive assembly 50. The box door 20 is hingedly arranged on one side of the box body 10, the flexible sealing assembly 30 is installed on the inner wall of the box body 10, the piston assembly 40 is arranged on the inner wall of the box door 20 and is connected to the flexible sealing assembly 30, one end of the rotary drive assembly 50 extends to the outside of the box door 20, and the other end extends to the inside of the box door 20. When the box door 20 is closed on one side of the box door 10, the rotary drive assembly 50 drives the piston assembly 40 to move to pressurize air into the flexible sealing assembly 30, so that the flexible sealing assembly 30 expands and then seals the gap between the box door 20 and the box body 10.

[0020] When the cable branch box is in normal operation, the box door 20 is in a closed state on one side of the box body 10. At this time, the rotary drive assembly 50 drives the piston assembly 40 to move, thereby pressing air into the flexible sealing assembly 30. When the flexible sealing assembly 30 is filled with air, it can expand, thereby sealing the gap between the box door 20 and the box body 10 to prevent rainwater from seeping into the box body 10 through the gap between the box door 20 and the box body 10, thereby preventing the electrical components inside the box body 10 from being damaged by moisture.

[0021] See also Figure 3 as well as Figure 5In one embodiment, the flexible sealing assembly 30 includes a rectangular frame 301 and a flexible layer 302. The rectangular frame 301 is fixedly arranged inside the box body 10 near the box door 20. A rectangular air duct 303 is opened on the side of the rectangular frame 301 facing the box door 20, and the flexible layer 302 is embedded in the rectangular air duct 303.

[0022] When the door 20 is closed on one side of the box body 10, the rectangular frame 301 is in contact with the inner wall edge of the door 20, and the piston assembly 40 is driven to move by the rotating drive assembly 50. The piston assembly 40 presses air into the rectangular airway 303 in the rectangular frame 301, thereby driving the flexible layer 302 to expand. When the flexible layer 302 expands, it fills into the gap between the door 20 and the box body 10, thereby blocking the gap between the door 20 and the box body 10 to isolate the outside rainwater and prevent the outside rainwater from seeping into the inside of the box body 10.

[0023] See also Figure 1 , Figure 4 as well as Figure 5 In one embodiment, the rotary drive assembly 50 includes a rotating wheel 502, an arc block 503 and a rotating shaft 505, wherein the rotating shaft 505 passes through the box door 20 and rotates with the box door 20, the rotating wheel 502 is fixedly arranged on the shaft body of the rotating shaft 505 located on the inner side of the box door 20, the arc block 503 is fixedly installed on the circumferential side wall of the rotating wheel 502, the piston assembly 40 includes a flexible air pipe 401, a piston cylinder 402 and a piston rod 404, the piston cylinder 402 is fixedly installed on the inner wall of the box door 20, one end of the piston rod 404 extends to the inside of the piston cylinder 402 and telescopically cooperates with the piston cylinder 402, and the other end extends to the outside of the piston cylinder 402 and abuts against the circumferential side wall of the rotating wheel 502, one end of the flexible air pipe 401 is connected to the inner cavity of the piston cylinder 402, and the other end is connected to the rectangular airway 303 in the rectangular frame 301.

[0024] When the door 20 is closed on one side of the box body 10, the staff can rotate the shaft 505, thereby driving the rotating wheel 502 to rotate. When the rotating wheel 502 rotates, it drives the arc block 503 to rotate. When the arc block 503 rotates, it pushes the piston rod 404 so that the piston rod 404 is pushed into the piston cylinder 402, and then the air inside the piston cylinder 402 is pressed into the rectangular air channel 303 through the flexible air pipe 401, thereby driving the flexible layer 302 to expand and fill the gap between the door 20 and the box body 10, so that the gap between the door 20 and the box body 10 is blocked, so as to prevent external rainwater from seeping into the box body 10 through the gap between the door 20 and the box body 10, thereby achieving effective protection of the electrical components inside the box body 10.

[0025] See also Figure 1In one embodiment, a hand wheel 501 is fixedly provided on the shaft 505 located on the outside of the door 20 .

[0026] By setting the hand wheel 501 , the staff can conveniently rotate the rotating shaft 505 .

[0027] See also Figure 5 In one embodiment, an elastic member 403 is further provided inside the piston cylinder 402 , and the elastic member 403 is used to provide elastic support for the piston rod 404 , so that the end of the piston rod 404 located outside the piston cylinder 402 can be tightly against the circumferential side wall of the rotating wheel 502 .

[0028] In one embodiment, the elastic member 403 may be a spring or a metal spring, which is not limited here.

[0029] See also Figure 2 as well as Figure 4 In one embodiment, a limiting groove 101 is provided on the inner wall of the box body 10 , and a limiting rod 504 is fixedly provided on the shaft body of the rotating shaft 505 located on the inner side of the box door 20 , and the limiting rod 504 and the rotating shaft 505 are perpendicular to each other.

[0030] When the rotating shaft 505 drives the rotating wheel 502 to rotate and then drives the piston rod 404 to move into the piston cylinder 402, the rotating shaft 505 can also drive the limiting rod 504 to rotate. When the flexible layer 302 expands and fills the gap between the box door 20 and the box body 10, the limiting rod 504 rotates into the limiting groove 101, so that the box door 20 cannot rotate toward the outside of the box body 10, thereby achieving the limitation of the box door 20.

[0031] See also Figure 2 In one embodiment, the limiting groove 101 is opened on a side of the rectangular frame 301 away from the door 20 .

[0032] When the door 20 is closed on one side of the box body 10, the end of the shaft 505 located on the inner side of the door 20 passes over the rectangular frame 301. In the subsequent rotation operation of the shaft 505, the shaft 505 can drive the limiting rod 504 to rotate, and the limiting rod 504 naturally rotates into the limiting groove 101 to limit the door 20. By setting the limiting groove 101 on the side of the rectangular frame 301 away from the door 20, the expansion of the flexible layer 302 is not hindered by the limiting rod 504, and the expanded flexible layer 302 can smoothly fill the gap between the door 20 and the box body 10 and seal the gap.

[0033] See also Figure 4 In one embodiment, a shift lever 201 is fixedly provided on the inner wall of the door 20 .

[0034] When the door 20 needs to be opened, the hand wheel 501 can be rotated in the reverse direction, thereby driving the rotating shaft 505, the rotating wheel 502, the arc block 503 and the limiting rod 504 to rotate in the reverse direction. When the limiting rod 504 rotates in the reverse direction, it rotates out from the limiting groove 101 to release the limit of the door 20. When the arc block 503 rotates in the reverse direction, the elastic member 403 pushes the piston rod 404 so that the piston rod 404 moves to the outside of the piston cylinder 402, so that the air inside the rectangular airway 303 is drawn to the piston cylinder through the flexible air pipe 401. 402, the flexible layer 302 collapses and withdraws from the gap between the box door 20 and the box body 10. When one end of the piston rod 404 abuts against the circumferential side wall of the rotating wheel 502 again, the limiting rod 504 acts on the blocking rod 201, and the blocking rod 201 limits the reverse rotation of the limiting rod 504, thereby limiting the reverse rotation of the rotating shaft 505 and the rotating wheel 502. At this time, the hand wheel 501 is pulled, thereby driving the box door 20 to rotate relative to the box body 10, thereby realizing the convenient opening of the box body 10.

[0035] In one embodiment, the flexible layer 302 may be a rubber layer or a silicone layer, which is not limited here.

[0036] In the embodiment of the present invention, when the cable branch box is in normal operation, the box door 20 is in a closed state on one side of the box body 10. At this time, the rotary drive assembly 50 drives the piston assembly 40 to move, thereby pressing air into the flexible sealing assembly 30. When the flexible sealing assembly 30 is filled with air, it can expand, thereby sealing the gap between the box door 20 and the box body 10 to prevent rainwater from penetrating into the box body 10 through the gap between the box door 20 and the box body 10, and avoiding damage to the electrical components inside the box body 10 due to moisture. Compared with the prior art, the gap between the box door 20 and the box body 10 can be effectively sealed, thereby preventing external rainwater from penetrating into the box body 10 through the gap between the box door 20 and the box body 10, thereby improving the moisture-proof protection effect of the electrical components inside the box body 10.

[0037] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-limiting from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention, and any reference numerals in the claims should not be regarded as limiting the claims involved.
