Technical Field

[0001] The utility model relates to the technical field of electrical engineering, in particular to an electrical control cabinet capable of increasing the sealing performance of cable connections. Background Art

[0002] As an indispensable part of the power system, the electrical control cabinet is responsible for the assembly and operation of switchgear, measuring instruments, protective electrical appliances and auxiliary equipment. As a key device for controlling and distributing electric energy, the performance and reliability of the electrical control cabinet are crucial. The sealing of the cable connection is one of the important factors affecting the normal operation and safety of the electrical control cabinet.

[0003] At present, common electrical control cabinets have some problems in cable connection: each connection point of the existing multiple cables is prone to loosening and falling off, making it not well sealed and easily causing electrical failures. In addition, the traditional heat dissipation method of the electrical control cabinet only has several vents on both sides of the cabinet, and the heat dissipation effect is poor. Therefore, we have launched a new electrical control cabinet that can increase the sealing of cable connections. Utility Model Content

[0004] The main purpose of the utility model is to provide an electrical control cabinet that can increase the sealing performance of cable connections, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] The sliding device includes a sliding plate, a hand-grip groove is opened at the front upper end of the sliding plate, and a plurality of wire-threading grooves are opened at the front upper end of the sliding plate. The plurality of wire-threading grooves are all located at the rear side of the hand-grip groove. A fixed component is fixedly connected to the middle upper end of the sliding plate, and the sliding plate is slidably connected in the electrical control cabinet.

[0008] Preferably, the fixing assembly includes a base plate and a pressure plate, the upper left portion and the upper right portion of the base plate are fixedly connected with screws, the outer surfaces of the two screws are threadedly connected with fixing bolts, the upper middle portion of the base plate is fixedly connected with a plurality of sealing components, the lower middle portion of the pressure plate is provided with a plurality of upper pressure grooves, the lower left portion and the lower right portion of the pressure plate are provided with a No. 1 movable hole, the pressure plate is pressed onto the upper outer surfaces of the plurality of sealing components, and the base plate is fixedly connected to the upper middle portion of the sliding plate.

[0009] By adopting the above technical solution: this structural design provides a stable and adjustable fixing and sealing method, the base plate is used to support and install the sealing component, the screw and the fixing bolt enable the pressure plate to apply pressure to firmly fix the cable on the sealing component to achieve a reliable sealing effect.

[0010] Preferably, the sealing component comprises a soft rubber tube, an inner wall of the soft rubber tube is fixedly connected with an elastic circular pad, an inner wall of the elastic circular pad is fixedly connected with an anti-slip layer, and the soft rubber tube is fixedly connected to the upper end of the bottom plate.

[0011] By adopting the above technical solution: the soft rubber tube provides external protection and preliminary sealing, the elastic round pad enhances the ability to adapt to the shape of the cable and improves the sealing fit, and the anti-slip layer increases the friction with the cable to prevent the cable from sliding, thereby jointly ensuring a good sealing and fixing effect.

[0012] Preferably, the plurality of sealing components are equidistantly spaced laterally and are located one by one directly behind the wire threading groove.

[0013] By adopting the above technical solution, the cables can be directly sealed and fixed to the sealing components after passing through the threading groove, thereby ensuring the regularity of the layout and the convenience of operation.

[0014] Preferably, the positional dimensions of the two screw rods correspond to the positional dimensions of the two No. 1 movable holes.

[0015] By adopting the above technical solution: it is ensured that the pressure plate can be accurately installed on the screw rod, and through the tightening effect of the fixing bolt, uniform pressure is applied to the sealing component and the cable, thereby ensuring the stability and reliability of the sealing and fixing.

[0016] Preferably, the position size of the soft rubber tube is matched with the position size of a plurality of upper pressing grooves.

[0017] By adopting the above technical solution: when the pressure plate is pressed down, the accurate cooperation between the upper pressure groove and the soft rubber tube can make the soft rubber tube evenly stressed, further improving the consistency and stability of the sealing effect, and ensuring comprehensive sealing of the cable.

The sealing component is composed of a soft rubber tube, an elastic round pad and an anti-slip layer, which can closely fit the outer surface of the cable to form a preliminary seal. The cable and the sealing component are firmly fixed together through the fastening structure of the bottom plate, the screw rod, the fixing bolt and the pressing plate to prevent the cable from loosening or falling off, and at the same time further enhance the sealing effect. Good sealing helps to prevent external factors such as dust and moisture from invading the interior of the electrical control cabinet, reducing the probability of electrical failure, and solving the problem that each connection point of the existing multiple cables is prone to loosening and falling off, so that it does not have good sealing and is prone to electrical failure.

[0020] In the utility model, the heat dissipation area is increased by installing the heat dissipation fins in the groove in the middle part of the lower end of the electrical control cabinet, which helps to dissipate the heat inside the electrical control cabinet to the external environment. The ventilation slots on the left and right ends of the electrical control cabinet and the fan in the circular box in the middle part of the upper end work together to form an effective air circulation path. Starting the fan can accelerate the discharge of hot air and the intake of cold air, significantly improving the heat dissipation effect, and effectively solving the problem that the traditional heat dissipation method of the electrical control cabinet only has a plurality of vents on both sides of the cabinet, resulting in poor heat dissipation effect.

[0030] An electrical control cabinet capable of increasing the sealing performance of cable connections comprises an electrical control cabinet body 1, a groove 7 is provided in the middle of the lower end of the electrical control cabinet body 1, a plurality of heat dissipation fins 8 are fixedly connected in the groove 7, a plurality of ventilation slots 4 are provided at the left and right ends of the electrical control cabinet body 1, a round box body 2 is fixedly connected at the middle of the upper end of the electrical control cabinet body 1, a fan 3 is inserted and connected at the middle of the upper end of the round box body 2, a slide groove 6 is provided between the left cabinet wall and the right cabinet wall of the electrical control cabinet body 1, a sliding device 5 is slidably connected between the left cabinet wall and the right cabinet wall of the electrical control cabinet body 1, two sliding devices 5 are provided, and the two sliding devices 5 are symmetrically distributed up and down.

[0031] In this embodiment, the sliding device 5 includes a sliding plate 51, a hand-grip groove 53 is opened at the front of the upper end of the sliding plate 51, and a plurality of threading grooves 52 are opened at the front of the upper end of the sliding plate 51, and the plurality of threading grooves 52 are all located at the rear side of the hand-grip groove 53. A fixing component 54 is fixedly connected to the middle of the upper end of the sliding plate 51, and the sliding plate 51 is slidably connected in the electrical control cabinet 1; the fixing component 54 includes a bottom plate 547 and a pressure plate 541, and the upper left part and the upper right part of the bottom plate 547 are fixedly connected to screw rods 545, and the outer surfaces of the two screw rods 545 are threadedly connected to fixing bolts 54 4. A plurality of sealing components 546 are fixedly connected to the middle of the upper end of the bottom plate 547, a plurality of upper pressing grooves 543 are opened in the middle of the lower end of the pressing plate 541, and a No. 1 movable hole 542 is opened in the left and right parts of the lower end of the pressing plate 541. The pressing plate 541 is pressed and fixed on the upper part of the outer surface of the plurality of sealing components 546, and the bottom plate 547 is fixedly connected to the middle of the upper end of the sliding plate 51; the plurality of sealing components 546 are equidistantly spaced laterally and are located one by one directly behind the threading groove 52; the position and size of the two screw rods 545 correspond to the position and size of the two No. 1 movable holes 542.

[0032] Through the above scheme: the sliding plate 51 is slidably connected in the electrical control cabinet 1, and the sliding plate 51 can be easily pulled out or pushed into the cabinet through the buckle groove 53, and the cable passes through the threading groove 52 to reach the fixing component 54. In the fixing component 54, the sealing component 546 on the bottom plate 547 corresponds to the threading groove 52, and the cable passes through the sealing component 546. Then, the pressing plate 541 is sleeved on the screw rod 545 through the No. 1 movable hole 542, and the fixing bolt 544 is rotated to make the fixing bolt 544 move downward along the screw rod 545, thereby pushing the pressing plate 541 to be pressed and fixed on the sealing component 546, so as to fix and seal the cable. When installing or removing the cable, the operator can easily pull out the sliding plate 51 through the hand groove 53 for operation. The cooperation of the sealing component 546, the pressure plate 541 and the fixing bolt 544 can provide a tight seal for the cables passing through, effectively preventing dust, moisture, etc. from entering the interior of the electrical control cabinet, thereby ensuring the normal operation and service life of the electrical equipment. Through the tightening action of the screw 545 and the fixing bolt 544, the pressure plate 541 can be firmly pressed on the sealing component 546 and the cable to prevent the cable from loosening or shifting during use. This sliding and fixed sealing design can adapt to cables of different quantities and specifications, and has high flexibility and versatility.

[0033] In this embodiment, the sealing component 546 includes a soft rubber tube 5461, the inner wall of the soft rubber tube 5461 is fixedly connected with an elastic circular pad 5462, the inner wall of the elastic circular pad 5462 is fixedly connected with an anti-slip layer 5463, and the soft rubber tube 5461 is fixedly connected to the upper end of the bottom plate 547; the position and size of the soft rubber tube 5461 are adapted to the position and size of the plurality of upper pressure grooves 543.

[0034] Through the above scheme: when the cable passes through the sealing component 546, it will first contact the anti-skid layer 5463. The anti-skid layer 5463 increases the friction with the cable surface and helps to prevent the cable from sliding. The elastic round pad 5462 can adapt to the shape of the cable and provide a certain elastic buffer, so that the contact between the cable and the sealing component 546 is closer. The soft rubber tube 5461, as an outer supporting structure, will produce a certain deformation when it is subjected to the pressure of the pressing plate 541, so as to further wrap the cable. When the pressing plate 541 is pressed down, the upper pressing groove 543 cooperates with the soft rubber tube 5461, so that the soft rubber tube 5461 is compressed more evenly. To enhance the sealing and fixing effect of the cable, the multi-layer structure of the soft rubber tube 5461, the elastic round pad 5462 and the anti-slip layer 5463 can block the entry of external dust, moisture, etc. layer by layer, greatly improving the sealing effect of the cable connection part. In a humid environment, it can effectively prevent moisture penetration and protect the components inside the electrical control cabinet 1 from being damaged by moisture. The adaptation of the soft rubber tube 5461 and the upper pressure groove 543 allows the pressure applied by the pressure plate 541 to be evenly distributed on the soft rubber tube 5461, ensuring the consistency and stability of the sealing effect. During long-term use, the cable sheath will not be damaged due to the extrusion of the sealing components.

[0035] It should be noted that the utility model is an electrical control cabinet that can increase the sealing of cable connections. During use, the heat dissipation fins 8 in the groove 7 in the middle of the lower end of the electrical control cabinet 1 are used to enhance the heat dissipation effect of the cabinet. The ventilation slots 4 at the left and right ends of the cabinet and the fan 3 in the circular box 2 in the middle of the upper end of the cabinet work together to promote air circulation, take away the heat generated inside the cabinet, and maintain a suitable working temperature. The sliding plate 51 in the sliding device 5 can slide inside the cabinet to facilitate operation and maintenance. The cable passes through the threading groove 52 and is fixed and sealed by the fixing component 54. The sealing component 546 on the bottom plate 547 is located directly behind the threading groove 52. When the cable passes through, the soft rubber tube 5461, the elastic round pad 5462 and the anti-slip layer 5463 in the sealing component 546 can tightly It fits the outer surface of the cable to play a preliminary sealing and fixing role. The pressure plate 541 is sleeved on the screw 545 through the No. 1 movable hole 542 on the left and right parts of its lower end, and is pressed against the upper outer surface of the sealing component 546 using the fixing bolt 544, further enhancing the fixing and sealing effect of the cable and preventing dust, moisture, etc. from entering the interior of the cabinet, thereby increasing the sealing of the cable connection. In actual work, when the temperature inside the electrical control cabinet 1 rises, the fan 3 starts, cold air enters from the ventilation slot 4, and hot air is discharged to ensure the normal operation of the equipment. When the cable needs to be connected, pull out the sliding plate 51, pass the cable through the threading slot 52 and the sealing component 546, and then tighten the fixing bolt 544 to make the pressure plate 541 press the sealing component 546 and the cable to achieve good sealing and fixing.
