Description

Technical Field

[0001] This invention relates to the field of electrical engineering technology, specifically to a cable protection device for electrical engineering that is moisture-proof and leak-proof. Background Technology

[0002] Electrical engineering construction involves numerous circuit connections. Some complex circuits have extensive cable structures during assembly. To improve the protection of these cables during installation, a protective device is used to seal and protect them, extending their lifespan. An electrical engineering cable protection device (application number CN201921992076.1) enables parallel cable installation, preventing cable burn-out and vibration during use. It also improves heat dissipation and facilitates easier assembly and disassembly. However, it is less effective for complex circuit structures and has limited management of cable surface moisture and leakage protection. The protection device still has certain problems in providing external cable protection.

[0003] 1. When this device is used for a long time in an environment with high air humidity, some moisture can easily seep into the inside of the protection device. The inside of the device is in a relatively sealed state and there is no dehumidification and leakage prevention structure, which is not conducive to the safe use of cables.

[0004] 2. For complex circuit connection structures, there are a large number of cables, and a large number of cables pass through the protection device. Their distribution is relatively messy, making it difficult to quickly find the cables during later maintenance or circuit inspection, which is a defect in the application.

[0005] Therefore, it is necessary to design an electrical engineering cable protection device that is moisture-proof and leak-proof to address the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a cable protection device for electrical engineering that is moisture-proof and leak-proof, in order to solve the problems mentioned in the background art. When the device is used for a long time in an environment with high air humidity, some moisture can easily seep into the interior of the protection device. The interior of the device is in a relatively sealed state and there is no dehumidification and leakage prevention structure, which is not conducive to the safe use of cables. For complex circuit connection structures with a large number of cables, a large number of cables pass through the protection device and their distribution is relatively messy. It is not convenient to quickly find the cables during later maintenance or circuit inspection, and there are defects in the application.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a cable protection device for electrical engineering with moisture-proof and leakage-proof features. The cable protection device mainly consists of an outer insulating protective box, a sealing door, and an inner insulating protective box. The sealing door is rotatably installed on the front side of the outer insulating protective box, and the inner insulating protective box is fixedly installed in the middle of the inner side of the outer insulating protective box.

[0008] An electrical engineering cable protection device with moisture-proof and leakage-proof features, comprising:

[0009] A humidity sensor is fitted and fixed inside the outer insulating protective box, and a threaded shaft is rotatably installed in the middle position inside the outer insulating protective box. A sliding rod is fixed inside the outer insulating protective box, and a dehumidification mechanism is sleeved and installed outside the sliding rod and the threaded shaft.

[0010] The controller is fixedly installed in the middle of the upper part of the inner insulating protective box, and electric heating plates are embedded and fixed on both the left and right sides of the inner insulating protective box. The electric heating plates are electrically connected to the controller, and ventilation grooves are opened at the bottom of both the inner and outer insulating protective boxes.

[0011] A sealing base plate is fitted into the bottom of the inner insulation protective box, and round rods are symmetrically fixed on both sides inside the inner insulation protective box. Slip rings are sleeved on the outside of the round rods, and the sides of the slip rings are connected to the combing rings through connecting rods. The combing rings are correspondingly engaged with the outside of the cable.

[0012] Preferably, the dehumidification mechanism has an overall inverted "U" shape, and the dehumidification mechanism includes a fixed frame and a mounting frame:

[0013] A fixing frame has an adjusting block fixed in the middle of its inner side, and a circular groove is opened inside the fixing frame;

[0014] The mounting bracket is symmetrically fixed on both sides of the front end of the fixed frame, and the mounting bracket is fitted with absorbent cotton inside, and the mounting bracket has a heating groove on its side.

[0015] Preferably, the mounting bracket pushes the absorbent cotton to adhere to the inner side of the outer insulation protective box, and the side of the mounting bracket forms an up-and-down sliding structure with a fixed bracket and a sliding rod. The inner side of the fixed bracket forms a threaded transmission structure with an adjusting block and a threaded shaft. The micro motor at the upper end of the outer insulation protective box controls the rotation of the threaded shaft. Under the control of the threaded transmission structure, the dehumidification mechanism moves up and down, and the dehumidification mechanism can clean the water that has seeped into the inner wall of the outer insulation protective box.

[0016] Preferably, the absorbent cotton is positioned on the side of the electric heating plate via a heating groove on the side of the mounting bracket, and the mounting bracket is positioned on the upper end of the induction block. During the up-and-down movement of the dehumidification mechanism, the electric heating plate heats the absorbent cotton on the side via the heating groove, evaporating the absorbed moisture and maintaining the long-term dehumidification effect of the dehumidification mechanism.

[0017] Preferably, the sealing base plate and the inner insulating protective box form a transverse telescopic sliding structure, and the side of the sealing base plate is also provided with a limit spring and a sliding frame:

[0018] A limiting spring is fixedly installed between the sealing base plates on the left and right sides. An elastic airbag is fixedly installed on the lower surface of the sealing base plate, and a fixing plate is welded and fixed on the outer side of the sealing base plate.

[0019] The sliding frame is connected to the fixed plate on its side by a support frame, and a straight sliding groove is provided on the outside of the sliding frame. The straight sliding groove is fixedly installed on the inner side of the outer insulating protective box, and a sensing block is fixedly installed on the upper surface of the sliding frame.

[0020] Preferably, the sealing base plate is disposed between the ventilation grooves opened at the bottom of the outer insulation protective box and the inner insulation protective box, and the sealing base plate controls the elastic airbag to be embedded in the ventilation groove at the lower end. When the sealing base plate is pushed to move laterally at the junction of the outer insulation protective box and the inner insulation protective box by the transmission structure, the ventilation groove is partially open, which facilitates the flow of internal and external gas and can treat the moisture inside the device.

[0021] Preferably, the lower end of the sensing block forms an up-and-down sliding structure with the linear slide groove via a sliding frame, and the lower end of the sliding frame is rotatably connected to one end of the support frame, and the other end of the support frame is rotatably connected to the fixed plate. When the dehumidification mechanism moves to the lowest position, the sensing block pushes the sliding frame to move downward, and under the transmission action of the support frame, it can push the sealing base plate to slide laterally.

[0022] Preferably, the slip ring and the round rod form an up-and-down damping sliding structure, and four comb rings are fixedly arranged at equal intervals on the inner side of the slip ring through a connecting rod. The outer side of the slip ring is connected to the protrusion through a positioning rod. The protrusion is fixedly installed on the outside of the handwheel, and the handwheel is rotatably located in the middle of the inner wall of the inner insulating protective box. Rotating the handwheel controls the rotation of the protrusion, which can push the slip ring to slide up and down.

[0023] Preferably, the two ends of the positioning rod form a rotating structure with the protrusion and the slip ring respectively, and the side of the protrusion has an elliptical structure. When the handwheel controls the rotation of the protrusion, the protrusion drives the positioning rods on the upper and lower sides to rotate accordingly, and the positioning rods can control the longitudinal sliding of the slip ring.

[0024] Preferably, the combing rings are arranged in groups of four, with two groups corresponding to each other inside the inner insulation protection box, and the combing rings are engaged outside the cable to achieve classified management.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows: This electrical engineering cable protection device with moisture-proof and leakage-proof features a novel structural design, which allows the device to easily sense and process internal moisture, increasing the safety of cable connections. Simultaneously, the device incorporates a cable management structure, resulting in a more orderly cable distribution within the device, facilitating engineering maintenance. The specific details are as follows:

[0026] 1. This electrical engineering cable protection device, which is moisture-proof and leak-proof, is equipped with an internal dehumidification and leak-proof structure. When the device is used for a long time in a high-humidity environment, some moisture seeps into the interior of the outer insulating protective box. Under the sensing action of the humidity sensor, the controller controls the micro motor to rotate the threaded shaft. Under the action of the threaded transmission structure, the dehumidification mechanism slides up and down on the inner side wall of the outer insulating protective box. When the absorbent cotton moves against the inner side wall of the outer insulating protective box, it can absorb the moisture that has entered the inner side wall. At the same time, the controller controls the operation of the electric heating plate. The heat generated by the electric heating plate is transferred to the interior of the absorbent cotton through the heating groove, which can heat the absorbent cotton and maintain the long-term dehumidification effect of the dehumidification mechanism. When the dehumidification mechanism moves to the bottom position, it pushes the sensing block to move downward. Under the pushing action of the sliding frame and support rod, it controls the lateral movement of the sealing base plate, thereby controlling the opening of the ventilation groove, facilitating the air flow inside and outside the device, and further assisting the internal dehumidification treatment of the device.

[0027] 2. This electrical engineering cable protection device, which is moisture-proof and leak-proof, is equipped with a cable sorting structure. The position of the sorting structure is adjusted according to the number of cables and their corresponding positions within the device. A handwheel controls the rotation of a cam, which, under the pushing action of a connecting rod, controls the sliding ring to slide up and down on the outside of the round rod. This controls the position of the sorting rings within the inner insulation protection box, ensuring the sorting rings engage with the cables on the outside. Based on the cable classification, the corresponding cables are secured and pass through the corresponding sorting rings, resulting in a more regular cable distribution within the inner insulation protection box, facilitating later cable location and maintenance.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figure 1-8 The present invention provides a technical solution: a cable protection device for electrical engineering with moisture-proof and leakage-proof features. The cable protection device mainly consists of an outer insulating protective box 1, a sealing door 2, and an inner insulating protective box 3. The sealing door 2 is rotatably installed on the front side of the outer insulating protective box 1, and the inner insulating protective box 3 is fixedly installed in the middle position inside the outer insulating protective box 1.

[0039] An electrical engineering cable protection device with moisture-proof and leakage-proof features, comprising:

[0040] Humidity sensor 4 is fitted and fixed inside the outer insulating protective box 1, and a threaded shaft 9 is rotatably installed in the middle position inside the outer insulating protective box 1. A slide rod 8 is fixed inside the outer insulating protective box 1, and a dehumidification mechanism 10 is sleeved and installed outside the slide rod 8 and the threaded shaft 9.

[0041] The controller 5 is fixedly installed in the middle of the upper part of the inner insulating protective box 3. Electric heating plates 6 are embedded and fixed on both the left and right sides of the inner insulating protective box 3. The electric heating plates 6 are electrically connected to the controller 5. Ventilation grooves 7 are opened at the bottom of both the inner insulating protective box 3 and the outer insulating protective box 1.

[0042] A sealing base plate 11 is fitted into the bottom of the inner insulation protection box 3. Round rods 19 are symmetrically fixed on both sides inside the inner insulation protection box 3. A slip ring 20 is sleeved on the outside of the round rods 19. The side of the slip ring 20 is connected to the combing ring 21 through the connecting rod 22. The combing ring 21 is correspondingly engaged on the outside of the cable.

[0043] In this example, the dehumidification mechanism 10 has an overall inverted "U" shape and includes a fixed frame 101 and a mounting frame 104. The fixed frame 101 has an adjusting block 102 fixed in the middle of its inner side, and a circular groove 103 is opened inside the fixed frame 101. The mounting frame 104 is symmetrically fixed on both sides of the front end of the fixed frame 101, and water-absorbing cotton 105 is embedded and fixed inside the mounting frame 104. A heating groove 106 is opened on the side of the mounting frame 104. The mounting frame 104 pushes the water-absorbing cotton 105 to adhere to the inner side of the outer insulating protective box 1. The side of the mounting frame 104 forms an up-and-down sliding structure with the slide rod 8 through the fixed frame 101. The inner side of the fixed frame 101 forms a threaded transmission structure with the threaded shaft 9 through the adjusting block 102. The water-absorbing cotton 105 corresponds to the side of the electric heating plate 6 through the heating groove 106 opened on the side of the mounting frame 104. The mounting frame 104 is correspondingly set at the upper end of the sensing block 17.

[0044] When the device is placed in a high-humidity environment for extended periods, some external moisture seeps into the interior of the outer insulating protective box 1. Under the sensing action of the humidity sensor 4, the controller 5 controls the operation of the electric heating plate 6 and the micro motor. The micro motor controls the rotation of the threaded shaft 9 at its lower end, which, under the action of the threaded transmission structure, controls the corresponding up-and-down movement of the dehumidification mechanism 10. The adjusting block 102 moves longitudinally outside the threaded shaft 9, and the fixing bracket 101 slides up and down outside the slide rod 8. The fixing bracket 101 pushes the mounting brackets 104 on both sides to move up and down. The absorbent cotton 105 embedded on the side of the mounting bracket 104 is attached to the inner wall of the outer insulating protective box 1 and moves accordingly. The absorbent cotton 105 can absorb and treat the moisture entering from the inner wall of the outer insulating protective box 1, effectively achieving dehumidification. Simultaneously, the heating groove 106 on the side of the mounting bracket 104 is correspondingly positioned on the side of the electric heating plate 6. The heat generated by the electric heating plate 6 is transferred to the surface of the absorbent cotton 105 through the heating groove 106, maintaining the long-term dehumidification effect of the dehumidification mechanism 10.

[0045] The sealing base plate 11 and the inner insulating protective box 3 form a transverse telescopic sliding structure. The side of the sealing base plate 11 is also equipped with a limit spring 12 and a sliding frame 16. The limit spring 12 is fixedly installed between the left and right sides of the sealing base plate 11. An elastic airbag 13 is fixedly installed on the lower surface of the sealing base plate 11, and a fixing plate 14 is welded and fixed to the outer side of the sealing base plate 11. The sliding frame 16 is connected to the fixing plate 14 on its side via a support frame 15, and a straight slide groove 18 is fitted on the outside of the sliding frame 16. The straight slide groove 18 is fixed... A sensing block 17 is fixedly installed on the inner side of the outer insulating protective box 1 and on the upper surface of the sliding frame 16; a sealing base plate 11 is set between the ventilation grooves 7 opened at the bottom of the outer insulating protective box 1 and the inner insulating protective box 3, and the sealing base plate 11 controls the elastic airbag 13 to be fitted into the ventilation groove 7 at the lower end; the lower end of the sensing block 17 forms an up-and-down sliding structure with the linear slide groove 18 through the sliding frame 16, and the lower end of the sliding frame 16 is rotatably connected to one end of the support frame 15, and the other end of the support frame 15 is rotatably connected to the fixing plate 14;

[0046] When the dehumidification mechanism 10 moves to the lowest position, it pushes the sensing block 17 downward. The sensing block 17 controls the sliding frame 16 to slide downward inside the linear slide groove 18. The sliding frame 16 controls the two ends of the support frame 15 to rotate accordingly. The lower end of the support frame 15 pushes the sealing base plate 11 to slide laterally at the bottom of the inner insulation protective box 3 through the fixing plate 14. At this time, the corresponding ventilation grooves 7 on the upper and lower sides of the sealing base plate 11 are partially open, which facilitates the convection of gas inside and outside the device and can assist the dehumidification process of the device. When the dehumidification mechanism 10 moves upward, the limiting spring 12 on the side of the sealing base plate 11 pushes it to move outward under the elastic action, so that the sensing block 17 moves upward in the opposite direction. This process is repeated. This part of the structure can keep the device in a sealed state under normal conditions, making the device more insulated and increasing the safety of cable connection applications.

[0047] The slip ring 20 and the round rod 19 form an upper and lower damping sliding structure. Four combing rings 21 are fixedly arranged at equal intervals on the inner side of the slip ring 20 through the connecting rod 22. The outer side of the slip ring 20 is connected to the protrusion 24 through the positioning rod 25. The protrusion 24 is fixedly installed on the outside of the handwheel 23, and the handwheel 23 is rotatably positioned in the middle of the inner wall of the inner insulation protection box 3. The two ends of the positioning rod 25 form a rotating structure with the protrusion 24 and the slip ring 20 respectively, and the side of the protrusion 24 is elliptical. The combing rings 21 are arranged in groups of four in two sets inside the inner insulation protection box 3, and the combing rings 21 are engaged on the outside of the cable to achieve classified management.

[0048] When the cable connection structure is complex, it is necessary to sort the cables inside the inner insulation protection box 3. The handwheel 23 controls the rotation of the protrusion 24, and the positioning rods 25 on both sides of the protrusion 24 rotate accordingly. The positioning rods 25 push the slip ring 20 to slide on the outside of the round rod 19 (the inner wall of the slip ring 20 has a large contact friction with the round rod 19. After controlling it to move to the corresponding position, the slip ring 20 stays on the outside of the round rod 19. The weight of the sorting ring 21 and the connecting rod 22 fixed on its side is small, so it will not affect the movement position of the slip ring 20 under the action of gravity). After the slip ring 20 is moved to the corresponding position, the position of the sorting ring 21 is limited. The cables are sorted and connected through the clip inside the sorting ring 21. This makes it easy for the staff to quickly find the corresponding cable structure and also facilitates the maintenance of the cables.

[0049] Working principle: When using this device, according to Figure 1-8As shown in the diagram, when some moisture enters the inner wall of the outer insulating protective box 1, the controller 5, under the action of the humidity sensor 4, controls the micro motor to rotate the threaded shaft 9. Under the action of the transmission structure, the dehumidification mechanism 10 moves up and down inside the device, causing the absorbent cotton 105 to move correspondingly against the inner wall of the outer insulating protective box 1, thus achieving the function of water absorption and dehumidification. When the dehumidification mechanism 10 moves to the lowest position, it pushes the sensing block 17 downwards. Under the pushing action of the sliding frame 16 and the support frame 15, the sealing base plate 11 can be controlled within the inner insulating protective box 3. The bottom slides horizontally, making a portion of the ventilation groove 7 open, which facilitates the flow of gas inside the device and assists in dehumidification. At the same time, the corresponding position of the combing ring 21 is adjusted according to the cable distribution inside the inner insulation protection box 3. The handwheel 23 is turned to control the rotation of the protrusion 24, and the two ends of the positioning rod 25 rotate to push the sliding ring 20 to slide correspondingly outside the round rod 19. This can adjust the position of the combing ring 21, which makes it easier for the device to comb the cables, so that the cables are more regularly distributed inside the inner insulation protection box 3, which facilitates the quick search and maintenance of cables later.

[0050] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
