Description

Technical Field

[0001] The utility model belongs to the technical field of power distribution cabinets, and in particular relates to an anti-leakage internal protection type power distribution cabinet. Background Art

[0002] Most of the existing power distribution cabinets are not equipped with a cable fixing mechanism when in use, so it is difficult to clamp and fix multiple different connecting wires in an orderly manner to prevent the connecting wires from being mixed and entangled. When the connecting wires are mixed and entangled, they may cause a short circuit in the connecting wires, thereby posing a risk of leakage.

[0003] The existing patent (application number: CN218648400U) proposes a distribution cabinet with anti-leakage protection, which relates to the field of anti-leakage technology of distribution cabinets; and the utility model includes a distribution cabinet, and a connecting rectangular block is fixedly connected to the inner wall of the distribution cabinet, and a connecting hole is opened on the surface of the connecting rectangular block; when in use, when installing the connecting wires, the connecting wires need to be placed between the two clamping moving blocks, and then the threaded connecting tube is rotated to drive the rotating tube to move toward the side close to the clamping moving block, thereby making the clamping moving block move toward both sides of the connecting wires and clamping both sides of the connecting wires to prevent them from moving. Therefore, when the distribution cabinet is in use, the connecting wires can be clamped and fixed, so that they are arranged in an orderly manner, preventing short circuits caused by the connecting wires being entangled together, and thus preventing the distribution cabinet from leaking.

[0004] The above device separates the wires to prevent the risk of leakage caused by the entanglement of the wires. It is necessary to rotate the threaded connecting tube to drive the rotating tube to move toward the side close to the clamping movable block, so that the clamping movable block moves to both sides of the connected wires and clamps the two sides of the connected wires. There are many wires in the distribution box. If it is necessary to check whether the wires are damaged and there is a risk of leakage, it is necessary to rotate multiple threaded connecting tubes to take out the wires and then inspect them. This is relatively inefficient and very troublesome.

[0005] In view of this, this application is hereby filed. Utility Model Content

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0029] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0030] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; and direct connections or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0031] In an existing anti-leakage internal protection distribution cabinet, since it is necessary to rotate the threaded connecting tube to drive the rotating tube to move toward the side close to the clamping movable block, and then the clamping movable block moves toward both sides of the connecting wires and clamps both sides of the connecting wires, it is necessary to set up a linkage clamping block device.

[0032] like Figures 1 to 4The utility model provides an internal protection type power distribution cabinet that is anti-leakage.

[0033] Specifically, by Figure 1-4 A leakage-proof internal protection distribution cabinet is provided, comprising a distribution box body 1, wherein a fixed wire assembly 2 for preventing wire entanglement is installed inside the distribution box body 1, and the fixed wire assembly 2 comprises a servo motor 201, and the servo motor 201 is installed on the inner bottom wall of the distribution box body 1, and a roller 202 is installed at the driving end of the servo motor 201, and a rotating rod 204 is installed on the top of the roller 202, and the external transmission of the rotating rod 204 is connected to a belt 203, and the rotating rod 204 is wrapped with a plurality of pull ropes 205, and the inner wall of the distribution box body 1 is installed with a plurality of L-shaped blocks 209 and a mounting block 206, and a tension spring 207 is installed on one side of the plurality of mounting blocks 206, and a clamping block 208 is installed on the other end of the tension spring 207, and the other end of the pull rope 205 is installed on the outer wall of the clamping block 208.

[0034] In the present invention, the accumulation of wires in the distribution cabinet may increase the risk of electric leakage. When installing the distribution wires, the staff controls the servo motor 201 to start, and the roller 202 includes a main body, a first split, and a second split. The servo motor 201 drives the roller 202 main body to rotate. When the main body rotates, the belt 203 drives the first split and the second split to rotate, thereby driving multiple rotating rods 204 to rotate. When the rotating rod 204 rotates, the pull rope 205 is wound around the outer wall. The pull rope 205 pulls the clamping block 208 to move toward the rotating rod 204, and the tension spring 207 is squeezed and retracted. The clamping block 208 and the L-shaped block 209 are both provided with arc grooves adapted to the distribution wires. At this time, the processed distribution wires are placed in multiple arc grooves respectively. After the distribution wires are placed, the servo motor 201 The driving end rotates in the opposite direction to loosen the pull rope 205 wrapped around the rotating rod 204, and the tension spring 207 returns to its original state according to the spring return principle. The elastic force of the tension spring 207 will press the clamping block 208 to the left, fixing the distribution line inside the through hole formed by the two arc-shaped grooves, clamping the distribution line, and allowing the wires to be distributed in an orderly manner inside the distribution cabinet to prevent short circuits or electric shocks between the wires when the wires are too dense or cross-wound. When the wires are entangled and piled up, the insulation between the wires may be damaged, thereby increasing the possibility of leakage. The above structure can be set in linkage to pull out multiple clamping blocks 208 at the same time, which is convenient for placing and arranging the distribution lines, does not require manual operation, and improves work efficiency.

[0035] Furthermore, as a specific embodiment of the present invention, the present invention provides an internally protected power distribution cabinet that is anti-leakage.

[0036] Specifically, such as Figure 2It is shown that a protrusion 4 is installed on the outer wall of the clamping block 208 , and a sliding groove 5 adapted to the protrusion 4 is opened on one side of the L-shaped block 209 , and the protrusion 4 is slidably connected to the inside of the sliding groove 5 .

[0037] In the present invention, the protrusion 4 can better guide the clamping block 208 to move in the horizontal direction. When the tension spring 207 pulls the clamping block 208 back, the clamping block 208 will not deviate from the direction because the mutual cooperation between the slide groove 5 and the protrusion 4 makes the clamping block 208 smoother when sliding and will not get stuck.

[0038] Furthermore, as another specific embodiment of the present invention, the present invention provides an internally protected power distribution cabinet that is anti-leakage.

[0039] Specifically, such as Figure 2 It is shown that the outer portion of the rotating rod 204 is sleeved with a connecting block 8 , which is mounted on the inner wall of the distribution box body 1 , and the rotating rod 204 is rotatably connected to the inner portion of the connecting block 8 .

[0040] In the present invention, the rotating rod 204 is longer, and the connecting block 8 prevents the rotating rod 204 from vibrating or deviating when rotating. If the rotating rod 204 deviates or vibrates during rotation, it may affect the pull rope 205 from pulling the clamping block 208. The connecting block 8 allows the rotating rod 204 to rotate at a fixed position, and the rotating rod 204 has better stability during rotation.

[0041] Furthermore, as another specific embodiment of the present invention, the present invention provides an internally protected power distribution cabinet that is anti-leakage.

[0042] Specifically, such as Figure 2 The inner wall of the distribution box body 1 is provided with an insulating anti-leakage layer 11, one side of the distribution box body 1 is connected to a box door 9, the inner wall of the box door 9 is connected to an insulating rubber layer 10, and the distribution box body 1 is provided with an insulating anti-leakage layer 11.

[0043] In the present invention, the support legs 12 can keep the distribution box body 1 away from the ground to prevent the distribution box body 1 from getting damp and leaking electricity. The insulating anti-leakage layer 11 is a protective layer used on electrical equipment or power lines. Its main function is to prevent current leakage and leakage. This layer is usually made of insulating materials, such as polymers, rubber or insulating paint. The insulating rubber layer 10 can effectively prevent current from leaking from the conductor or contacting the external environment, reducing potential harm to other devices or the human body. The lead wire 6 can lead the leaked electricity into the ground.

[0044] Furthermore, as another specific embodiment of the present invention, the present invention provides an internally protected power distribution cabinet that is anti-leakage.

[0045] Specifically, such as Figure 2It is shown that a mounting base is sleeved on the outer wall of the servo motor 201 , and the mounting base is connected to the inner bottom wall of the distribution box body 1 .

[0046] In the present invention, the mounting base can fix the servo motor 201 in a specific position to prevent the servo motor 201 from generating noise due to vibration during operation. If the servo motor 201 is displaced due to vibration during operation, the fixed wire components 2 cannot cooperate with each other normally, and ultimately the distribution wires cannot be fixed well.

[0047] Furthermore, as another specific embodiment of the present invention, the present invention provides an internally protected power distribution cabinet that is anti-leakage.

[0048] Specifically, such as Figure 2 The present invention also includes a heat dissipation component 3, which is installed on the inner wall of the distribution box body 1. The heat dissipation component 3 includes a mounting frame 301, and a DC motor 302 is installed inside the mounting frame 301. The driving end of the DC motor 302 is connected to a bidirectional screw rod 303, and the bidirectional screw rod 303 is rotatably connected to the inside of the mounting frame 301. The external thread of the bidirectional screw rod 303 is connected to multiple sliders 304, and the outer walls of the multiple sliders 304 are installed with connecting rods 305, and a fan 306 is installed at the end of the connecting rod 305 away from the slider 304.

[0049] In the present invention, leakage is likely to occur when the temperature of the distribution box is too high. In a high temperature environment, the insulating material of the cable line will be severely corroded and aged. After the insulation is damaged, the cable line is prone to leakage, short circuit and other faults. At the same time, the insulation layer of the wire is prone to aging and brittleness, resulting in line short circuit or leakage, and then causing serious accidents such as fire. A temperature sensor is provided inside the distribution box body 1. When the temperature sensor senses a high temperature, the DC motor 302 is started, and the driving end of the DC motor 302 drives the bidirectional screw rod 303 to rotate. The rotation of the bidirectional screw rod 303 drives the slider 304 to slide left and right. The slider 304 drives the fan 306 to move in a straight line through the connecting rod 305, blowing cool air to the distribution line, and the hot air is dissipated from the vents on both sides. This can effectively prevent the temperature inside the distribution box from being too high, poor heat dissipation, overload or overheating of the distribution line, so as to reduce the risk of leakage and other safety problems.

[0050] Furthermore, as another specific embodiment of the present invention, the present invention provides an internally protected power distribution cabinet that is anti-leakage.

[0051] Specifically, such as Figure 2 It is shown that a limiting rod 7 is installed inside the mounting frame 301 , and the slider 304 is slidably connected to the outer wall of the limiting rod 7 .

[0052] In the present invention, the limit rod 7 can prevent the slider 304 from rotating when the bidirectional screw rod 303 rotates, causing the wind blown by the fan 306 to be unable to be well aligned with the distribution line, which cannot quickly accelerate the volatilization of heat on the distribution line. If this continues for a long time, the overheating may accelerate the aging of the insulation layer on the distribution line.

[0053] Furthermore, as another specific embodiment of the present invention, the present invention provides an internally protected power distribution cabinet that is anti-leakage.

[0054] Specifically, such as Figure 2 It is shown that the outer wall of the distribution box body 1 is provided with a plurality of ventilation holes, and filters are installed inside the ventilation holes.

[0055] In the present invention, the hot air generated by the fan 306 blowing towards the distribution line can be blown out through the vents to prevent heat from accumulating inside the distribution box body 1. Excessive temperature will accelerate the aging of the insulation layer of the distribution line. The filter can better prevent external dust from entering the distribution box, and can play a better dust-proof role.

[0056] Working principle: The accumulation of entangled wires in the distribution cabinet may increase the risk of electric leakage. When installing the distribution wires, the staff controls the servo motor 201 to start, and the roller 202 includes a main body, a first split, and a second split. The servo motor 201 drives the roller 202 main body to rotate. When the main body rotates, the belt 203 drives the first split and the second split to rotate, thereby driving multiple rotating rods 204 to rotate. When the rotating rod 204 rotates, the pull rope 205 is wrapped around the outer wall. The pull rope 205 pulls the clamping block 208 to move toward the rotating rod 204, and the tension spring 207 is squeezed and retracted. The clamping block 208 and the L-shaped block 209 are both provided with arc grooves adapted to the distribution wires. At this time, the processed distribution wires are placed in multiple arc grooves respectively. After the distribution wires are placed, the servo motor 201 is turned on. The driving end rotates in the opposite direction to loosen the pull rope 205 wrapped around the rotating rod 204, and the tension spring 207 returns to its original state according to the spring return principle. The elastic force of the tension spring 207 will press the clamp 208 to the left, fixing the distribution line inside the through hole formed by the two arc-shaped grooves, clamping the distribution line, and allowing the wires to be distributed in an orderly manner inside the distribution cabinet to prevent short circuits or electric shocks between the wires when the wires are too dense or cross-wound. When the wires are entangled and piled up, the insulation between the wires may be damaged, thereby increasing the possibility of leakage. With the above structure, multiple clamps 208 can be pulled out at the same time through a linkage setting, which is convenient for placing and arranging the distribution lines, does not require manual operation, and improves work efficiency.

[0057] If the temperature of the distribution box is too high, leakage is likely to occur. In a high temperature environment, the insulation material of the cable will be severely corroded and aged. After the insulation is damaged, the cable is prone to leakage, short circuit and other faults. At the same time, the insulation layer of the wire is prone to aging and brittle, resulting in line short circuit or leakage, and then causing serious accidents such as fire. A temperature sensor is provided inside the distribution box body 1. When the temperature sensor senses a high temperature, the DC motor 302 is started, and the driving end of the DC motor 302 drives the bidirectional screw rod 303 to rotate. The rotation of the bidirectional screw rod 303 drives the slider 304 to slide left and right. The slider 304 drives the fan 306 to move in a straight line through the connecting rod 305, blowing cool air to the distribution line, and the hot air is dissipated from the vents on both sides. This can effectively prevent the temperature inside the distribution box from being too high, poor heat dissipation, overload or overheating of the distribution line, so as to reduce the risk of leakage and other safety problems.

[0058] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments with equivalent changes using the technical content suggested above without departing from the scope of the technical solution of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
