Description
Technical Field
[0001] This utility model relates to the field of power safety technology, specifically to a leak-proof device with insulating gel for power safety use. Background Technology
[0002] In power systems, power wells (such as cable wells, inspection wells, and distribution wells) are core nodes of underground power facilities, playing a crucial role in cable laying, inspection, and maintenance. However, power wells are constantly exposed to a damp underground environment, making them susceptible to equipment failure due to rainwater, groundwater, and moisture seepage. Leakage prevention devices are core protective equipment designed to address this problem, preventing moisture intrusion through physical sealing and structural barriers, thereby ensuring the safe and stable operation of power facilities.
[0003] For example, comparing a device for preventing water leakage at the opening of a power pipe well with Chinese patent publication number CN223329890U, which belongs to the field of waterproof construction technology, the device includes a power pipe well. A pre-embedded pipe is embedded in the outer wall of one side of the power pipe well, and a cable is installed inside the pre-embedded pipe. A manhole cover is placed on top of the power pipe well, and a limiting block is set inside the power pipe well below the manhole cover. Limiting grooves are symmetrically opened on both sides of the limiting block on the inner wall of the power pipe well. This solution can clamp the waterproof cover to the top of the power pipe well by turning the fixing ring, thereby sealing the connection between the power pipe well and the manhole cover.
[0004] However, it is not convenient to drain rainwater that has seeped into the gaps. When the power well is subjected to rainwater erosion for a long time, due to stress fatigue and facility aging, some water vapor can easily seep into the gaps between the well cover and the pipe. As the water vapor gradually increases, it will condense into water droplets, thereby eroding the anti-leakage device, shortening its service life, and even threatening power safety. Utility Model Content
[0005] The purpose of this invention is to provide a leak-proof device with insulating gel for safe use in electrical systems, which can drain water droplets that have entered the well cover, thereby improving the electrical safety factor.
[0006] To achieve this objective, the present invention adopts the following technical solution:
[0007] A leak-proof device with insulating gel for electrical safety is provided, comprising a manhole, a manhole cover, a locking assembly, and a drainage assembly. The top of the manhole has a trapezoidal groove that fits snugly against the manhole cover. An insulating gel ring is fixedly connected to the bottom wall of the manhole cover, with the bottom of the insulating gel ring abutting against the bottom wall of the trapezoidal groove. A collection groove is formed on the inner wall of the trapezoidal groove. The locking assembly is installed on the manhole cover to ensure a tight fit between the manhole cover and the manhole. A secondary chamber is fixedly connected to the side wall of the manhole. The drainage assembly includes a drainage pipe and a one-way extraction mechanism. The drainage pipe passes through the secondary chamber and is fixedly connected thereto, with one end of the drainage pipe communicating with the collection groove. The one-way extraction mechanism is installed in the secondary chamber and is used to extract water from the collection groove.
[0008] Furthermore, the unidirectional extraction mechanism includes a piston, a pull rod, multiple sleeves, multiple slide rods, multiple baffles, and multiple first tension springs. The piston is slidably connected to the inner wall of the drain pipe. One end of the pull rod is fixedly connected to the piston. A through circular hole is opened at one end of the piston. A drain outlet is opened at the bottom of the end of the drain pipe away from the well. The sleeve is fixedly connected to the inner wall of the drain pipe. The sleeve passes through the circular hole and is slidably connected to it. The diameter of the sleeve is smaller than the diameter of the circular hole. One end of the slide rod passes through the sleeve and is slidably connected to its inner wall. The other end of the slide rod is fixedly connected to the baffle. The baffle and the end of the circular hole away from the well abut against each other. The two ends of the first tension spring are fixedly connected to the slide rod and the inner wall of the sleeve, respectively.
[0009] Furthermore, the number of drainage pipes and the number of unidirectional extraction mechanisms are both a pair. The two drainage pipes are fixedly connected to both sides of the well. The drainage assembly also includes a drive mechanism, which includes a rotating plate. The middle part of the rotating plate is rotatably connected to the inner wall of the auxiliary chamber, and the two sides of the rotating plate are rotatably connected to the other ends of two tie rods respectively.
[0010] Furthermore, the drive mechanism also includes a motor, a turntable, and a connecting rod. The top of the motor is fixedly connected to the inner wall of the auxiliary chamber, the output shaft of the motor passes through the inner wall of the auxiliary chamber and is coaxially connected to the turntable, the eccentric part of the turntable is rotatably connected to one end of the connecting rod, and the other end of the connecting rod is rotatably connected to one side of the rotating plate.
[0011] Furthermore, grooves are provided on both sides of the rotating plate, and the inner wall of the groove is slidably connected to the end of the pull rod away from the piston.
[0012] Furthermore, the bottom wall of the auxiliary chamber has multiple through holes, with the drain outlet located above the through holes.
[0013] Furthermore, the locking assembly includes a pair of insert rods, multiple second tension springs, and a compression plate. The insert rods pass through the side wall of the manhole cover and are slidably connected to it. A slot is provided on the inner wall of the manhole. One end of the insert rod has a beveled structure and is inserted into the slot. The compression plate is rotatably connected to the inner wall of the manhole cover. A pair of arc-shaped protrusions are fixedly connected to the periphery of the compression plate. The arc-shaped protrusions abut against the other end of the insert rod. The two ends of the second tension springs are fixedly connected to the inner wall of the manhole cover and the insert rod, respectively.
[0014] Furthermore, the locking assembly also includes a circular plate, which is rotatably connected to the inner wall of the manhole cover. The top of the circular plate has a U-shaped groove, and the bottom of the circular plate is coaxially connected to the extrusion disc.
[0015] The beneficial effects of this utility model are as follows: By setting up a well, a well cover, and a drainage component, this utility model moves the well cover into the trapezoidal groove when sealing the well. The locking component applies downward pressure to the well cover, making the bottom of the well cover fit tightly against the bottom wall of the trapezoidal groove. At the same time, the insulating gel ring provides a seal to prevent rainwater from entering the well through the gap. After the rainwater enters the gap, it accumulates in the collection tank.

[0029] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0030] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of this utility model, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.
[0031] Reference Figures 1 to 7 The device shown is an electrical safety-grade anti-leakage device with insulating gel, comprising a manhole 1, a manhole cover 13, a locking assembly 2, and a drainage assembly 3. The top of the manhole 1 has a trapezoidal groove 10 that fits snugly against the manhole cover 13. An insulating gel ring 14 is fixedly connected to the bottom wall of the manhole cover 13, with the bottom of the insulating gel ring 14 abutting against the bottom wall of the trapezoidal groove 10. A collection groove 11 is formed on the inner wall of the trapezoidal groove 10. The locking assembly 2 is installed on the manhole cover 13 to ensure a tight fit between the manhole cover 13 and the manhole 1. A secondary chamber 15 is fixedly connected to the side wall of the manhole 1. The drainage assembly 3 includes a drainage pipe 30 and a one-way extraction mechanism 4. The drainage pipe 30 passes through and is fixedly connected to the secondary chamber 15, with one end of the drainage pipe 30 communicating with the collection groove 11. The one-way extraction mechanism 4 is installed in the secondary chamber 15 and is used to extract water from the collection groove 11.
[0032] When sealing the manhole 1, the manhole cover 13 is moved into the trapezoidal groove 10. The locking assembly 2 applies downward pressure to the manhole cover 13, so that the bottom of the manhole cover 13 fits tightly against the bottom wall of the trapezoidal groove 10. At the same time, the insulating gel ring 14 provides a seal to prevent rainwater from entering the manhole 1 through the gap. After the rainwater enters the gap, it accumulates in the collection tank 11. Then, the one-way extraction mechanism 4 is activated to extract the rainwater in the collection tank 11 through the drain pipe 30, which facilitates the drainage of the rainwater in the gap and improves the safety factor.
[0033] like Figures 5 to 7As shown, the one-way extraction mechanism 4 includes a piston 40, a pull rod 41, multiple sleeves 42, multiple slide rods 43, multiple baffles 44, and multiple first tension springs 45. The piston 40 is slidably connected to the inner wall of the drain pipe 30. One end of the pull rod 41 is fixedly connected to the piston 40. One end of the piston 40 has a through circular hole 400. The bottom of the drain pipe 30, which is away from the well 1, has a drain outlet 300. The sleeve 42 is fixedly connected to the inner wall of the drain pipe 30. The sleeve 42 passes through the circular hole 400 and is slidably connected to it. The diameter of the sleeve 42 is smaller than the diameter of the circular hole 400. One end of the slide rod 43 passes through the sleeve 42 and is slidably connected to its inner wall. The other end of the slide rod 43 is fixedly connected to the baffle 44. The baffle 44 and the end of the circular hole 400 away from the well 1 abut against each other. The two ends of the first tension springs 45 are fixedly connected to the slide rod 43 and the inner wall of the sleeve 42, respectively.
[0034] The number of drainage pipes 30 and the number of unidirectional extraction mechanisms 4 are both a pair. The two drainage pipes 30 are fixedly connected to both sides of the well 1. The drainage assembly 3 also includes a drive mechanism 31. The drive mechanism 31 includes a rotating plate 32. The middle part of the rotating plate 32 is rotatably connected to the inner wall of the auxiliary chamber 15. The two sides of the rotating plate 32 are rotatably connected to the other ends of two tie rods 41 respectively.
[0035] The drive mechanism 31 also includes a motor 33, a turntable 34 and a connecting rod 35. The top of the motor 33 is fixedly connected to the inner wall of the auxiliary chamber 15. The output shaft of the motor 33 passes through the inner wall of the auxiliary chamber 15 and is coaxially connected to the turntable 34. The eccentric part of the turntable 34 is rotatably connected to one end of the connecting rod 35, and the other end of the connecting rod 35 is rotatably connected to one side of the rotating plate 32.
[0036] Both sides of the rotating plate 32 are provided with sliding grooves 320, and the inner wall of the sliding groove 320 is slidably connected to the end of the pull rod 41 away from the piston 40.
[0037] The bottom wall of the auxiliary chamber 15 has multiple through holes 16, and the drain outlet 300 is located above the through holes 16.
[0038] The drain pipes 30 are configured as a pair, and the drive mechanism 31 synchronously drives two unidirectional extraction mechanisms 4 to work, which can improve drainage efficiency and thus meet the drainage needs of rainstorm weather. When the motor 33 is powered on, its output shaft drives the turntable 34 to rotate, causing one end of the connecting rod 35 to rotate around the eccentric part of the turntable 34. The other end of the connecting rod 35 drives one end of the rotating plate 32 to move back and forth, causing the rotating plate 32 to swing back and forth around its center, thereby simultaneously pushing and pulling the two pull rods 41. The movement of the pull rods 41 drives the piston 40 to slide inside the drain pipe 30. The first tension spring 45 is always in a stretched state. When the piston 40 slides towards the well 1, the tension of the first tension spring 45 causes the sliding rod 43 to drive the baffle 44 to move with the piston 40. One end of the sliding rod 43 is in the sleeve 4. The piston 40 slides inward, and the baffle 44 is in contact with one end of the piston 40. When the baffle 44 and the sleeve 42 come into contact with each other, as the piston 40 continues to move, the sleeve 42 passes through the round hole 400. At this time, the round hole 400 on the piston 40 can allow water to flow through. Then the piston 40 moves in the opposite direction. When it moves to contact the baffle 44, the round hole 400 is sealed. As the piston 40 continues to move, the water in the drain pipe 30 is pushed to the drain outlet 300 and falls down. Finally, it flows out through the through hole 16 at the bottom of the auxiliary chamber 15, thereby draining the rainwater in the gap and improving the seepage prevention effect.
[0039] like Figures 2 to 4 As shown, the locking assembly 2 includes a pair of insert rods 20, multiple second tension springs 21, and a compression plate 22. The insert rods 20 pass through the side wall of the manhole cover 13 and are slidably connected to it. A slot 12 is provided on the inner wall of the manhole 1. One end of the insert rod 20 has a beveled structure and is inserted into the slot 12. The compression plate 22 is rotatably connected to the inner wall of the manhole cover 13. A pair of arc-shaped protrusions 23 are fixedly connected to the periphery of the compression plate 22. The arc-shaped protrusions 23 abut against the other end of the insert rod 20. The two ends of the second tension springs 21 are fixedly connected to the inner wall of the manhole cover 13 and the insert rods 20, respectively.
[0040] The locking assembly 2 also includes a circular plate 24, which is rotatably connected to the inner wall of the manhole cover 13. A U-shaped groove 240 is provided on the top of the circular plate 24, and the bottom of the circular plate 24 is coaxially connected to the extrusion plate 22.
[0041] The U-shaped groove at the top of the circular plate 24 facilitates removal, ensuring the top of the manhole cover 13 is flush with the top of the manhole 1. After the manhole cover 13 is fitted against the inner wall of the trapezoidal groove 10, rotating the circular plate 24 causes the pressing disc 22 at its bottom to rotate inside the manhole cover 13. The arc-shaped protrusion 23 around the pressing disc 22 pushes out the insertion rod 20 as it rotates, stretching the second tension spring 21. One end of the insertion rod 20 inserts into the slot 12. As the insertion rod 20 inserts into the slot 12, its inclined surface abuts against the top wall of the slot 12, providing downward pressure to the manhole cover 13. This makes the seal between the manhole cover 13 and the manhole 1 tighter, further preventing leakage. Reversing the rotation of the circular plate 24 causes the second spring to rebound, pulling the insertion rod 20 into the manhole cover 13. Pulling the manhole cover 13 upwards then separates it from the manhole.
[0042] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model. However, such variations, as long as they do not depart from the spirit of this utility model, should be within the protection scope of this utility model. Furthermore, some terminology used in this application specification and claims is not limiting, but merely for ease of description.
