Description

Technical Field

[0001] This utility model relates to the field of cover plate technology, specifically a combined well cover plate adapted to cable sleeves. Background Technology

[0002] Current technology primarily involves attaching the submersible pump's outlet cable to the inner wall of the well casing. During operation, the cable sways due to water flow disturbances and rubs against the top of the unit and the well casing, resulting in a high cable damage rate and significant safety risks. Furthermore, the sealing plugs used where the cable passes through the cover plate have poor durability and frequent leaks.

[0003] Meanwhile, existing technologies use enclosed pipes to protect cables, but these are all rigidly connected to the unit and wellbore. When the unit shakes or is lifted, rigid stress is transmitted, causing excessive stress on the submersible pump wiring chamber and wellbore cover, resulting in damage. Therefore, we propose a combined wellbore cover that is compatible with cable sleeves. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a combined well cover plate adapted to cable conduits, which solves the problems of stress concentration, easy bending, easy backfilling, and complex assembly of submersible motor cable conduits mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a combined wellbore cover plate adapted to cable conduits, comprising a cover plate, a wellbore, and a cable conduit. The cover plate is installed on the top of the wellbore and consists of a flat plate, a cylinder, a guide pipe, an exhaust valve, bolts a, and a rubber ring.

[0006] The flat plate is a circular plate structure, which is installed on the top of the well shaft. The cylinder is a cylindrical structure located in the middle of the flat plate, and the cylinder and the flat plate are an integral structure. The cylinder and the flat plate are combined to form a "┷" shaped plate structure.

[0007] The cable conduit passes through the flat plate and the cylinder. A sealing assembly is provided on the cylinder, comprising an elastic sealing ring, a sealing pressure ring, and a protective buckle. The elastic sealing ring is located in the lower part of the inner cavity of the cylinder and has a circular structure that fits snugly against the inner wall of the cylinder.

[0008] The sealing ring is located in the upper part of the inner cavity of the cylinder and is located above the elastic sealing ring. The sealing ring has a "T"-shaped circular structure, and the top of the sealing ring extends to the outside of the cylinder and is connected to the cylinder by bolt two. The protective buckle is located on the top of the sealing ring.

[0009] As a further aspect of this solution, the upper diameter of the inner cavity of the cylinder is 20mm larger than the lower diameter of the inner cavity, and a guide pipe is provided on the upper side of the cylinder, with an inner diameter of 15mm.

[0010] As a further aspect of this solution, the exhaust valve is mounted on a flat plate, and the flat plate is provided with a vent pipe corresponding to the exhaust valve, and the vent pipe penetrates the flat plate.

[0011] As a further aspect of this solution, the elastic sealing ring is a circular annular structure made of elastic alloy composite material, resin, polyurethane, or polytetrafluoroethylene, etc., with a compression of 3-6 mm, and the inner wall of the sealing ring contacts and seals with the outer wall of the cable sleeve.

[0012] As a further aspect of this solution, the sealing pressure ring is used to press the elastic sealing ring onto the cylinder in a "T"-shaped ring. Four water-permeable holes are symmetrically distributed on the lower side of the sealing pressure ring. The four water-permeable holes are used to drain water that leaks from the elastic sealing ring into the gap inside the cylinder. The gap between the outer wall of the elastic sealing ring and the inner wall of the cylinder is 20mm, and the gap between the inside of the elastic sealing ring and the outer wall of the cable sleeve is 10mm.

[0013] As a further aspect of this solution, the protective buckle is a circular "T"-shaped rubber protective ring with a wall thickness of 5-10mm. The protective buckle is installed to the top of the sealing pressure ring by bolts.

[0014] As a further part of this solution, the plate has a wall thickness of 30mm to 50mm, the plate is connected to the well shaft by bolt a, bolt a is a high-strength bolt, the cylinder has a wall thickness of 30mm to 70mm, and the top of the cylinder (102) is 300mm higher than the top of the plate.

[0015] As a further aspect of this solution, the rubber ring is set in a groove on the bottom of the plate, and the rubber ring is located inside the bolt hole on the plate. The rubber ring is an "O" shaped rubber structure, and the inner cavity of the groove is rectangular or triangular.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1: Refer to Figure 1 This utility model provides a combined well cover plate adapted to cable sleeves, including a cover plate, a well shaft 5, and a cable sleeve 6.

[0022] The cover plate 100 is installed on the top of the well shaft 5 and is a key component for sealing the well shaft 5, preventing water from overflowing from inside the well shaft 5.

[0023] The cover plate 100 is composed of a flat plate 101, a cylinder 102, a guide pipe 103, an exhaust valve 104, bolts a106, and a rubber ring 107.

[0024] The plate 101 is a circular plate structure with a wall thickness of 30mm to 50mm. Bolt a106 is used to connect the plate 101 and 5. Bolt a106 is a high-strength bolt. Rubber ring 107 is set in a groove at the bottom of the plate 101 and is located inside the bolt hole on the plate 101. Rubber ring 107 is an "O" type rubber structure. The inner cavity of the groove is rectangular or triangular to prevent water from seeping out along the bolt connection.

[0025] The cylinder 102 is a cylindrical structure located in the middle of the plate 101, and the cylinder 102 and the plate 101 are an integral structure, forming a "┷" shaped plate structure. The wall thickness of the cylinder 102 is 30mm to 70mm, and the top of the cylinder 102 is 300mm higher than the top of the plate 101.

[0026] Furthermore, the upper diameter of the inner cavity of the cylinder 102 is 20mm larger than the lower diameter of the inner cavity. A guide pipe 103 is provided on the upper side of the cylinder 102, and the inner diameter of the guide pipe 103 is 15mm. The guide pipe 103 is used to drain the seepage water in the gap inside the cylinder 102.

[0027] The exhaust valve 104 is installed on the plate 101, and the plate 101 is provided with a vent pipe corresponding to the exhaust valve 104. The vent pipe passes through the plate 101. The use of the exhaust valve 104 satisfies the need for air to be vented when the well 5 is filled with water and the need for air to be vented when it is drained.

[0028] The top of the cylinder 102 is flange-shaped with threaded holes on its upper surface. The top edge of the cylinder 102 protrudes for securing it with ropes during hoisting. The cylinder 102 is equipped with a sealing assembly, which includes an elastic sealing ring 200, a sealing pressure ring 300, and a protective buckle ring 400. The elastic sealing ring 200 is located in the lower part of the inner cavity of the cylinder 102, and has a circular structure that fits snugly against the inner wall of the cylinder 102.

[0029] The cable sleeve 6 houses the cable and passes through the flat plate 101 and the cylinder 102. The sealing ring 300 is located in the upper part of the inner cavity of the cylinder 102 and is above the elastic sealing ring 200. The top of the sealing ring 300 extends to the outside of the cylinder 102 and is connected to the cylinder 102 by bolt 202. The elastic sealing ring 200 is a circular structure and is made of elastic alloy composite material or resin, polyurethane or polytetrafluoroethylene and other composite materials. The compression amount is 3 to 6 mm. It is pressed and installed in the lower part of the cylinder 102 by the sealing ring 300. The inner wall of the sealing ring 300 contacts and seals the outer wall of the cable sleeve 6, and allows the cable sleeve 6 to slide up and down.

[0030] The sealing ring 300 is a "T"-shaped ring-shaped component used to press the elastic sealing ring 200 onto the cylinder 102. Four water-permeable holes are symmetrically distributed on the lower side of the sealing ring 300. The four water-permeable holes are used to drain water that leaks from the elastic sealing ring 200 into the internal gap of the cylinder 102. The gap between the outer wall of the elastic sealing ring 200 and the inner wall of the cylinder 102 is 20mm, and the gap between the inside of the elastic sealing ring 200 and the outer wall of the cable sleeve 6 is 10mm.

[0031] The protective buckle 400 is located on top of the sealing pressure ring 300, and the protective buckle 400 is installed on the surface of the sealing pressure ring 300 by bolt 301. The protective buckle 400 is a circular "T"-shaped rubber protective ring with a wall thickness of 5-10mm. The end of the protective buckle 400 is located in the inner cavity of the cable sleeve 6 and contacts the outer side of the cable inside it. The protective buckle 400 is used to prevent the cable from being worn when it twists at the opening of the cable sleeve 6. The upper end of the cable sleeve 6 does not need to be filled with sealing glue.

[0032] In summary, when using this combined well cover plate with cable sleeve, the rubber ring 107 is placed into the groove at the bottom of the flat plate 101. Then, the flat plate 101 is lifted using hoisting equipment and the cylinder 102, and placed on the well 5. It is then fixed with bolts a106. At this time, the cable sleeve 6 passes through the flat plate 101 and the cylinder 102. To install the sealing assembly, the elastic sealing ring 200 is placed on the outside of the cable sleeve 6 and moved downwards so that it enters the lower part of the inner cavity of the cylinder 102. Then, the sealing pressure ring 300 is placed on the surface of the cable sleeve 6 and moved downwards so that the sealing pressure ring... The sealing ring 300 is inserted into the upper part of the inner cavity of the cylinder 102 and exerts downward pressure on the elastic sealing ring 200. The top of the sealing ring 300 is fixed to the top of the cylinder 102 using bolt 302. Finally, the protective buckle 400 is placed on the top of the cable sleeve 6 and the sealing ring 300, and its inner side is inserted into the inner cavity of the cable sleeve 6 to contact the cable, thereby forming a seal. This method is suitable for submersible motor well cover plates and is used to solve the problems of sealing the submersible motor cable sleeve passing through the well cover plate and preventing water backflow into the sleeve, as well as the problems of stress concentration, easy bending, easy backflow, and complex assembly of submersible motor cable sleeves.
