Description

Technical Field

[0001] This utility model relates to the technical field of sealing structure for submersible pump cables, and specifically to a sealing structure for a submersible pump cable. Background Technology

[0002] Currently, in water-filled submersible pumps, there is a sealing structure between the cable connector and the submersible motor coil connector. The main function of this structure is to connect and enclose the cable lead and motor lead inside the submersible motor, preventing water from entering the connector from the motor cavity or outside. Patent number CN201620410104.4 discloses a sealing structure for submersible pump cable connectors, which integrates the cable lead connector and the stator coil lead connector of the submersible pump into one unit, ensuring a reliable seal at the connector, improving the insulation performance of the submersible pump, and guaranteeing its operational safety and service life. However, since the external cables of the submersible pump are directly and fixedly connected to the internal stator coils, disassembly is inconvenient. This necessitates moving the coiled cable when handling or moving the submersible pump, which is inconvenient. Therefore, we propose a sealing structure for the submersible pump cable. Utility Model Content

[0003] To address the problems in the prior art, this utility model provides a sealing structure for a submersible pump cable.

[0004] The technical solution adopted by this utility model to solve its technical problem is a sealing structure for a submersible electric pump cable, including an electric pump body. The top surface of the electric pump body is integrally constructed with a pipe seat, and a flange sleeve is inserted into the top surface of the pipe seat. Bolts for fixing are assembled between the flange sleeve and the pipe seat, and there are multiple sets of bolts. A rubber sleeve is glued to the inside of the flange sleeve, and a cable is assembled inside the rubber sleeve. A plug is assembled at one end of the cable located inside the pipe seat, and a socket for plugging into the plug is assembled inside the pipe seat.

[0005] The flange sleeve and the pipe seat are both provided with annular grooves on their opposite sides, and the flange sleeve and the pipe seat are both integrally constructed with annular bodies that fit the annular grooves, and a rubber gasket is bonded to the inner side of the annular grooves.

[0006] By adopting the above technical solution, when using the submersible pump, the plug at the bottom of the cable can be inserted into the socket inside the pipe seat at the top of the pump body. Then, the rubber sleeve with an integral structure on the outer periphery of the cable can drive the flange sleeve glued to it to be inserted into the pipe seat. Then, the flange sleeve and the pipe seat are fixed with bolts, which prevents water from entering between the pipe seat and the flange sleeve, so that the pump body can operate stably. At the same time, it is convenient to disassemble the cable and the pump body, and it is easy to move the two separately.

[0007] When the pipe seat and flange are connected, the ring body and the ring groove between the two fit together, and the rubber gasket on the inner side of the ring body and the ring groove fit together, which helps to improve the tightness of the connection between the pipe seat and the flange, thereby reducing the possibility of water seeping into the gap between the two, so that the plug and socket between the two can conduct electricity more safely and stably.

[0008] Specifically, a groove is provided between the rubber sleeve and the flange sleeve, and there are multiple sets of grooves. A rubber ring is bonded to the inner side of the groove.

[0009] By adopting the above technical solution, the rubber ring is located inside the groove, and the rubber sleeve and the flange sleeve are glued together by pouring glue. With the cooperation between the groove and the rubber ring, the static friction between the rubber sleeve and the flange sleeve is improved, thereby improving the stability of the rubber sleeve and the flange sleeve after gluing.

[0010] Specifically, the top surface of the plug is integrally constructed with a ring block, and there are multiple sets of ring blocks.

[0011] By adopting the above technical solution, the ring block makes it easier to assemble and disassemble the plug.

[0012] Specifically, the electric pump body and the pipe seat are integrally constructed with inclined blocks, and there are multiple sets of inclined blocks.

[0013] By adopting the above technical solution, the inclined block can improve the stability of the pipe seat, thereby increasing the strength of the pipe seat.

[0014] Specifically, both the flange sleeve and the pipe seat are coated with a corrosion-resistant layer, and the corrosion-resistant layer is coated with a wear-resistant layer.

[0015] By adopting the above technical solution, the corrosion-resistant layer and the wear-resistant layer work together to improve the service life of the pipe seat and flange sleeve.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The technical solution of this application, through the design of pipe seat, flange sleeve, bolt, rubber sleeve, cable, plug and socket, enables the plug at the bottom of the cable to be inserted into the socket inside the pipe seat on the top of the pump body when the submersible pump is in use. Then, the rubber sleeve with an integral structure on the outer periphery of the cable can drive the flange sleeve glued to it to be inserted into the pipe seat. Then, the flange sleeve and the pipe seat are fixed with bolts, which prevents water from entering between the pipe seat and the flange sleeve, so that the pump body can operate stably. At the same time, it is convenient to disassemble the cable and the pump body, and facilitates the movement of both separately.

[0018] 2. The design of the annular groove, annular body, and rubber gasket in this application's technical solution ensures that when the pipe seat and flange sleeve are connected, the annular body and annular groove fit together, and the rubber gasket inside the annular groove fits together. This improves the tightness of the connection between the pipe seat and flange sleeve, thereby reducing the possibility of water seeping into the gap between them. This allows the plug and socket between them to conduct electricity more safely and stably. Attached Figure Description

[0026] When using the submersible pump, the plug 7 at the bottom of the cable 6 can be inserted into the socket 8 inside the pipe seat 2 on the top of the pump body 1. Then, the rubber sleeve 5, which is integrally constructed on the outer periphery of the cable 6, can drive the flange sleeve 3, which is glued to it, to be inserted into the pipe seat 2. Then, the flange sleeve 3 and the pipe seat 2 are fixed with bolts 4, so that water cannot enter between the pipe seat 2 and the flange sleeve 3, allowing the pump body 1 to operate stably. At the same time, it is convenient to disassemble the cable 6 and the pump body 1, and it is convenient to move the two separately.

[0027] When the pipe seat 2 and the flange sleeve 3 are connected, the ring body 10 and the ring groove 9 between them fit together. At the same time, the rubber gasket 11 on the inner side of the ring body 10 and the ring groove 9 fit together, which helps to improve the tightness of the connection between the pipe seat 2 and the flange sleeve 3, thereby reducing the situation of water seeping into the gap between them, so that the plug 7 and the socket 8 between them can conduct electricity more safely and stably.

[0028] like Figure 2 As shown, a groove 12 is provided between the rubber sleeve 5 and the flange sleeve 3, and there are multiple sets of grooves 12. A rubber ring 13 is bonded to the inner side of the groove 12.

[0029] During use, the rubber ring 13 is located inside the ring groove 12, and the rubber sleeve 5 and the flange sleeve 3 are glued together by pouring glue. With the cooperation between the ring groove 12 and the rubber ring 13, the static friction between the rubber sleeve 5 and the flange sleeve 3 is improved, thereby improving the stability of the rubber sleeve 5 and the flange sleeve 3 after gluing.

[0030] like Figure 2 As shown, the top surface of the plug 7 has an integrally formed ring block 14, and there are multiple sets of ring blocks 14.

[0031] When in use, the ring block 14 makes it easier to assemble and disassemble the plug 7.

[0032] like Figure 1 and Figure 2 As shown, the electric pump body 1 and the pipe seat 2 are integrally constructed with inclined blocks 17, and there are multiple sets of inclined blocks 17.

[0033] When in use, the wedge block 17 helps to improve the stability of the tube seat 2, thereby increasing the strength of the tube seat 2.

[0034] like Figure 3 As shown, both the flange sleeve 3 and the pipe seat 2 are coated with a corrosion-resistant layer 15, and the corrosion-resistant layer 15 is coated with a wear-resistant layer 16.

[0035] During use, the corrosion-resistant layer 15 and the wear-resistant layer 16 work together to improve the service life of the pipe seat 2 and the flange sleeve 3.

[0036] The working principle and usage process of this utility model are as follows: In use, first install the corresponding structural components in suitable positions. When using the submersible pump, the plug 7 at the bottom of the cable 6 can be inserted into the socket 8 inside the pipe seat 2 at the top of the pump body 1. Then, the integrally formed rubber sleeve 5 around the cable 6 can drive the flange sleeve 3, which is glued to it, to be inserted into the pipe seat 2. Finally, bolts 4 are used to fix the flange sleeve 3 and the pipe seat 2, preventing water from entering between the pipe seat 2 and the flange sleeve 3, thus allowing the pump body to... 1. It can operate stably and facilitates the disassembly of the cable 6 and the electric pump body 1, making it easy to move the two separately. When the pipe seat 2 and the flange sleeve 3 are connected, the ring body 10 and the ring groove 9 between the two fit together. At the same time, the rubber gasket 11 on the inner side of the ring body 10 and the ring groove 9 fit together, which can improve the tightness of the connection between the pipe seat 2 and the flange sleeve 3, thereby reducing the situation of water seeping into the gap between the two, so that the plug 7 and the socket 8 between the two can conduct electricity more safely and stably.
