Description

Technical Field

[0001] This utility model relates to the field of power engineering technology, and in particular to a maintenance device for cable laying in power engineering. Background Technology

[0002] Electrical engineering refers to the process of transmitting generated electrical energy through cables; cable laying refers to the process of laying and installing cables along a surveyed route to form a cable line; after the cable laying is completed, the cable needs to be inspected using tools inside the maintenance box to ensure that there are no safety hazards.

[0003] In the prior art, Chinese Patent Publication No. CN218482590U discloses a maintenance device for cable laying in power engineering, including a maintenance box. A limiting plate is symmetrically fixedly installed at the top of the front of the maintenance box, and a mounting groove is symmetrically opened at the top of the back of the maintenance box. A movable rod is fixedly installed inside the mounting groove, and a movable block is movably sleeved on the outer surface of the movable rod. A sealing cover is fixedly installed on the upper surface of the movable block. In the above solution, the maintenance device, by setting a limiting device, compresses two sets of limiting blocks inside the limiting device against the inner wall of the limiting frame when the maintenance tool is not in use. After compression to a certain distance, the distance between the two sets of limiting blocks increases. Then, the maintenance tool is placed inside the limiting frame. At this time, the compressed limiting blocks are released, and then a return spring restores the compressed limiting blocks to their original position, thereby limiting the maintenance tool and preventing it from falling, reducing losses.

[0004] However, in actual use, this utility model only prevents moisture by expelling humid air through a fan. After the internal air is expelled, the external air enters the maintenance box for circulation, and the external air still has a high humidity. Therefore, the moisture-proof effect is not ideal, and the air inside the maintenance box cannot be sufficiently moisturized and dried. Therefore, it needs to be improved. Utility Model Content

[0005] The purpose of this invention is to provide a maintenance device for cable laying in power engineering, which can effectively prevent internal moisture and has a more thorough dehumidification effect.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a maintenance device for laying cables in power engineering, including a maintenance box, the maintenance box having a flow cavity inside, an air inlet box fixedly connected to one side of the maintenance box, an air inlet pipe fixedly connected to one side of the air inlet box, a one-way valve fixedly connected to the outer surface of the air inlet pipe, an opening on the other side of the air inlet box, mesh openings on both sides of the inner wall of the maintenance box, a leak-proof cover snapped onto the top of the air inlet box, a dust removal mesh core movably installed at the bottom of the leak-proof cover, and a dehumidifying particle layer disposed inside the dust removal mesh core.

[0007] By adopting the above technical solution, when using the equipment, the dust collector core is installed at the bottom of the leak-proof cover, and the corresponding air inlet box is inserted. The leak-proof cover is then snapped into place at the top of the air inlet box. When dehumidification of the inside of the maintenance box is required, the one-way valve opens, and the flow chamber draws in and exhausts air. The mesh opening draws away the humid air inside the maintenance box. After exhaust, the flow chamber has a negative pressure, and external air enters through the air inlet pipe. The air is then cleaned by the dust collector core, preventing dust from entering the maintenance box and affecting the maintenance equipment. The dehumidifying particle layer removes moisture from the air, ensuring that the incoming air is moist and dry. After the air flows, the inside of the maintenance box is filled with dry air, thus effectively preventing internal dampness and achieving a more thorough dehumidification effect.

[0008] A further feature of this invention is that an activated carbon granule layer is provided on one side of the dehumidifying granule layer, and an anti-slip layer is fixedly connected to the top of the dust removal mesh core.

[0009] By adopting the above technical solution, the activated carbon granule layer has a certain filtration effect, which improves air quality, and the anti-slip layer increases the firmness of the dust collector core when it is fixed.

[0010] A further feature of this invention is that the bottom of the leak-proof cover is fixedly connected to a first buckle, and the bottom of the inner wall of the air intake box is fixedly connected to a second buckle.

[0011] By adopting the above technical solution, the first and second clips secure the dust collector mesh core, making it easy to replace at any time.

[0012] A further feature of this invention is that a moisture-proof platform is fixedly connected to the bottom of the inner wall of the inspection box, and air holes are provided on the outer surface of the moisture-proof platform.

[0013] By adopting the above technical solution, the air holes on the moisture-proof platform facilitate air circulation.

[0014] A further feature of this invention is that a high-voltage generator is provided on the top of the moisture-proof platform, and a limit plate is fixedly connected to the inner wall of the maintenance box.

[0015] By adopting the above technical solution, the limiting plate limits the high voltage generator, and the high voltage generator can be removed when the cable is being inspected.

[0016] A further feature of this invention is that the top of the moisture-proof platform is provided with a tool slot, and the bottom of the inner wall of the maintenance box is provided with a second mesh opening.

[0017] By adopting the above technical solution, the tool slot is used to place maintenance tools, and the second mesh port increases the airflow range.

[0018] A further feature of this invention is that an exhaust box is fixedly connected to the other side of the maintenance box, and a fan is fixedly connected to the inner wall of the exhaust box.

[0019] By adopting the above technical solution, the fan is started during dehumidification, and the exhaust box exhausts the air.

[0020] A further feature of this invention is that one end of the fan is fixedly connected to an exhaust pipe, and the other end of the fan is fixedly connected to an exhaust pipe.

[0021] By adopting the above technical solution, the air extraction tube extends into the interior of the flow chamber, thereby performing air extraction.

[0022] A further feature of this invention is that the top of the maintenance box is hinged to a sealed box cover, and the bottom of the maintenance box is provided with casters.

[0023] By adopting the above technical solution, the sealed box cover can be opened and closed, and the sealing performance is strong.

[0024] A further feature of this invention is that a first handle is fixedly connected to the top of the leak-proof cover, and a second handle is fixedly connected to the top of the sealing box cover.

[0025] By adopting the above technical solution, the first handle makes it easy to open the leak-proof cover upwards, and the second handle makes it easy to lift and move the maintenance box.

[0026] The beneficial effects of this utility model are:

[0027] 1. This utility model, through the coordinated arrangement of the maintenance box, flow chamber, air inlet box, air inlet pipe, one-way valve, port, mesh port, leak-proof cover, dust removal mesh core, and dehumidifying particle layer, enables the device to be used effectively. When the operator installs the dust removal mesh core at the bottom of the leak-proof cover, inserts it into the corresponding air inlet box, and the leak-proof cover engages with the top of the air inlet box. When dehumidification of the maintenance box is required, the one-way valve opens, the flow chamber draws in and exhausts air, and the mesh port draws away the humid air inside the maintenance box. After exhaust, the flow chamber has a negative pressure, allowing external air to enter through the air inlet pipe. The air is then cleaned by the dust removal mesh core, preventing dust from entering the maintenance box and affecting the maintenance equipment. The dehumidifying particle layer removes moisture from the air, ensuring the incoming air is moist and dry. After airflow, the interior of the maintenance box is filled with dry air, effectively preventing internal dampness and achieving a more thorough dehumidification effect.
