Description

Technical Field

[0001] The invention relates to the technical field of cable trench covers, and in particular to a cable trench visualization cover with a demisting function. Background Art

[0002] There are a large number of cable trenches in substations, which are filled with high-voltage cables and secondary cables connected to primary equipment. The cable trenches are sealed with covers. During the daily operation and maintenance of the substation, operators need to regularly inspect the internal conditions of the cable trenches. Currently, the covers used to seal the cable trenches are generally visual cable covers made of plexiglass. By installing the visual cable covers on the cable trenches, the internal conditions of the cable trenches can be directly observed through the glass. Due to the influence of factors such as temperature, fog or condensation easily forms on the inside of the visual cable trench covers, which does not dissipate for a long time and affects the observation of the internal conditions of the cable trench.

[0003] In the prior art, by arranging graphene heating films at both ends of the bottom of the transparent cover body, a large amount of heat can be generated, thereby evaporating the water vapor on the inner side of the transparent cover body and ensuring the clarity of the transparent cover body. In the prior art, the heat generated by the graphene heating films at both ends is transported to the center of the transparent cover body through the mutual cooperation between structures with heat-conducting effects to improve the use effect. However, the heat generated by the graphene heating films will have a large loss problem during the transportation process, resulting in poor effect when transporting the heat generated by the graphene heating films to the center position, which cannot effectively improve the use effect. In addition, the transportation of the heat generated by the graphene heating films at both ends requires the mutual cooperation between multiple electrical devices, which increases energy consumption.

Frosted areas 8 are provided at both ends of the bottom of the transparent cover body. The tops of the two graphene heating films 6 are provided with heat-conductive and heat-resistant adhesive layers 9.

[0033] Sealing gaskets 17 are fixedly mounted on the bottoms of the two top covers 16 , and handle grooves 18 are formed on the tops of the two top covers 16 .

[0034] The shielding mechanism includes two shielding plates 20, two guide rods 1 21 and two guide rods 23. Both sides of the two guide rods 1 21 are fixedly connected to the heating chamber 11. The two guide rods 1 21 are respectively slidably sleeved on the top and bottom of the two shielding plates 20. The tops of the two guide rods 23 are fixedly connected to the frame 1. The outsides of the two guide rods 23 are jointly slidably sleeved with a lifting frame 24. The outside of one of the guide rods 1 21 that are close to each other is sleeved with a spring 22. The tops of the two shielding plates 20 are each provided with a mounting block 25. The tops of the two mounting blocks 25 are each fixedly installed with a roller 26. The two sides of the bottom of the lifting frame 24 are both arranged with inclined surfaces, and the two rollers 26 are respectively in contact with the two inclined surfaces.

[0035] The sealing mechanism includes a flip assembly and a driving assembly. The flip assembly includes two fixed shafts 27 and two brackets 29. The two fixed shafts 27 are respectively fixedly installed on the tops of the two baffles 20. The tops of the two brackets 29 are fixedly connected to the lifting frame 24. The outsides of the two fixed shafts 27 are sleeved with torsion springs 28. The bottoms of the two brackets 29 are provided with strip slides 30. The insides of the two strip slides 30 are slidably installed with sliding rods 31. The two sliding rods 31 are fixedly installed with a circular limit frame 32 on one side close to the fixed shaft 27. The two circular limit frames 32 are respectively slidably set inside the two baffles 20. The tops of the two baffles 20 are fixedly installed with fixed side panels 40. The two fixed shafts 27 are respectively located between adjacent circular limit frames 32 and fixed side panels 40.

[0036] The driving assembly includes a cylinder 33, which is fixedly installed inside the heating chamber 11. A horizontal plate 34 is fixedly installed at the bottom of the telescopic shaft of the cylinder 33. Guide rods 35 are slidably sleeved at both ends of the horizontal plate 34. The tops of the two guide rods 35 are fixedly connected to the heating chamber 11. A connecting rod 1 36 is rotatably installed on the side of the two baffles 20 close to the horizontal plate 34. A connecting shaft 37 is fixedly installed on the ends of the two connecting rods 1 36 that are close to each other. A connecting shaft 37 is rotatably sleeved on the outside of the two connecting shafts 37. The ends of the two connecting rods 2 38 that are away from their respective corresponding connecting shafts 37 are rotatably connected to the inside of the heating chamber 11.

[0037] Working principle: When in use, the frame 1 is fixedly placed in a suitable position in the cable trench, and desiccant is respectively loaded into the two desiccant storage boxes 15. The two desiccant storage boxes 15 are then respectively installed in the two heating chambers 11. The process of installing one of the desiccant storage boxes 15 in a heating chamber 11 is as follows: the desiccant storage box 15 is placed in the placement rack 14, and then the handle groove 18 is used to lift the top cover 16, the placement rack 14 and the desiccant storage box 15, and the placement rack 14 is placed in the heating chamber 11. After placement, the sealing gasket 17 at the bottom of the top cover 16 contacts the inner wall of the frame 1. By inserting fixing bolts 19 at both ends of the top cover 16 and rotating the two fixing bolts 19 respectively, the top cover 16 and the frame 1 can be fixed. Under the action of the sealing gasket 17, the top cover 16 and the frame 1 are sealed. The installation process of the other desiccant storage box 15 is the same as above.

[0038] When one of the fixing bolts 19 is screwed into the interior of the frame 1, the corresponding shielding mechanism moves as follows: the fixing bolt 19 generates a downward force on the lifting frame 24, and the lifting frame 24 is forced to slide downward along the two guide rods 23. Since the two rollers 26 are in contact with the two inclined surfaces, when the lifting frame 24 descends, the two shielding plates 20 are forced to move away from each other along the two guide rods 1 21 at the same time, and the two springs 22 are stretched, so that the corresponding ventilation holes 12 are no longer blocked. At the same time, as the lifting frame 24 descends, the two brackets 29 are driven to descend synchronously, and the two brackets 29 drive their respective sliding rods 31 and the circular limit frames 32 to descend inside the corresponding shielding plates 20. Moreover, as the two shielding plates 20 move, the two sliding rods 31 also slide inside the two strip slide grooves 30 respectively. When the two shielding plates 20 move to the extreme ends, the two circular limit frames 32 also move to the bottom. When the remaining fixing bolts 19 are screwed into the frame 1 , the movement processes of the corresponding shielding mechanisms are the same as described above.

[0039] By starting the two fans 13, the gas inside the cable trench can enter the corresponding heating chambers 11 through the ventilation holes 12 away from the fans 13. Under the action of the desiccant, the moisture in the gas can be absorbed and then discharged outward through the ventilation holes 12 close to the fans 13. The desiccant can reduce the ambient humidity, and the two graphene heating films 6 directly eliminate surface condensation, providing double protection and improving the dehumidification effect of the cover. In addition, by using the desiccant to absorb moisture in the gas, the operating time of the two graphene heating films 6 can be reduced, thereby reducing energy consumption.

[0040] When the desiccant in the two desiccant storage boxes 15 is invalid, the four heating plates 39 can be used to heat and regenerate the desiccant in the two heating chambers 11, thereby extending the service life of the desiccant. The steps for heating the desiccant in one of the heating chambers 11 are as follows: first, turn off the fan 13, start the cylinder 33, and push the horizontal plate 34 to move downward along the two guide rods 35. The horizontal plate 34 acts on the two connecting shafts 37. The two connecting shafts 37 are downward, and the two connecting rods 1 36 and the two guide rods 35 are connected. When connecting rod 2 38 moves, the two shielding plates 20 simultaneously move toward each other. At this time, due to the limiting effect of the two fixed side plates 40 located on one side of the two mounting blocks 25, and the two circular limiting frames 32 moving downward no longer limiting the two mounting blocks 25, when the two shielding plates 20 move, the two rollers 26 drive the corresponding mounting blocks 25 to contact the lifting frame 24, and then rotate around their corresponding fixed shafts 27. The two shielding plates 20 can then move toward each other without hindrance, closing the ventilation holes 12. After the two ventilation holes 12 in the heating chamber 11 are closed, the two heating plates 39 can be activated to heat and regenerate the desiccant, thereby extending the service life of the desiccant. After heating is completed, the cylinder 33 is used to reset the cross plate 34, and the two shielding plates 20 are reset, and the interior of the cable trench is dehumidified. The desiccant heating steps in the other heating chamber 11 are the same as above.

[0041] When the desiccant inside a heating chamber 11 needs to be replaced: the two fixing bolts 19 are taken out by reversing, and under the action of the two springs 22, the two shielding plates 20 are reset to block the ventilation holes 12 again, thereby preventing the external moist air from entering the cable trench through the ventilation holes 12 when the desiccant is replaced. Then, the entire desiccant storage box 15 can be pulled out using the handle groove 18, and the desiccant inside it can be replaced.

[0042] Through the visual area 7 formed between the two graphene heating films 6, the staff can observe the internal situation of the cable trench through the visual area 7. Through the two graphene heating films 6, when the inner side of the transparent cover body is attached with fog or condensation, the two graphene heating films 6 are connected to the external circuit and turned on, which can generate a large amount of heat, thereby causing the inner side of the transparent cover body to heat up rapidly, and then evaporate the water vapor on the inner side of the transparent cover body, ensuring the clarity of the transparent cover body and improving the observation effect of the internal situation of the cable trench. Through the arrangement of the first glass layer 2, the intermediate film layer 3 and the second glass layer 4, the transparent cover body becomes a laminated glass, which effectively improves the explosion-proof performance of the transparent cover body and improves its safety. In addition, laminated glass has good thermal insulation effect , which can effectively isolate the heat transfer on the upper and lower sides of the transparent cover body, so that after the transparent cover body is defogged once, the visible area 7 can remain fog-free for a long time, thereby achieving energy saving. Since the surface of the frosted area 8 is frosted, the bonding strength between the heat-conductive and heat-resistant adhesive layer 9 and the contact surface of the transparent cover body can be effectively enhanced, thereby reducing the possibility of separation between the graphene heating film 6 and the transparent cover body, and ensuring that the inner side of the transparent cover body has a stable defogging effect. The transparent self-cleaning coating 5 is a transparent super-hydrophilic coating. After being washed by road water, the dirt attached to its surface can be quickly peeled off to achieve a self-cleaning effect. The two anti-slip films 10 provided can improve the anti-slip effect of the upper side of the transparent cover body, preventing pedestrians from slipping when accidentally stepping on it, thereby ensuring public safety.
