[0049] Combined with appendix Figure 1-5As shown, a submersible pump connection device according to this application is applied to a submersible pump 1. The submersible pump 1 is provided with a water outlet pipe 11 and a connecting pipe 12 connected together. A first fixing ring 13 is provided on the water outlet pipe 11, and a second fixing ring 14 is provided on the connecting pipe 12. The connection device is disposed between the water outlet pipe 11 and the connecting pipe 12. The connection device includes:

[0050] The first pressure plate 2 has a first fixing cavity inside it;

[0051] The second pressure plate 3 has a second fixing cavity inside it, and the first end of the first pressure plate 2 is rotatably connected to the first end of the second pressure plate 3.

[0052] The first clamping assembly 4 is mirror-disposed within the first fixing cavity;

[0053] The second clamping assembly 5 is mirror-disposed within the second fixing cavity;

[0054] When the second end of the first pressure plate 2 covers the second end of the second pressure plate 3, the first fixing ring 13 and the second fixing ring 14 are located between the first clamping assembly 4 and the second clamping assembly 5.

[0055] In this technical solution, the connecting device is applied to the submersible pump 1 to achieve stable connection between the outlet pipe 11 and the connecting pipe 12 of the submersible pump 1. The connecting device includes a first pressure plate 2, a second pressure plate 3, a first clamping assembly 4, and a second clamping assembly 5. The first pressure plate 2 has a first fixing cavity, and the second pressure plate 3 has a second fixing cavity. The first ends of the first pressure plate 2 and the second pressure plate 3 are rotatably connected. The first clamping assembly 4 is mirror-distributed in the first fixing cavity, and the second clamping assembly 5 is mirror-distributed in the second fixing cavity. When the second end of the first pressure plate 2 covers the second end of the second pressure plate 3, the first fixing ring 13 of the outlet pipe 11 and the second fixing ring 14 of the connecting pipe 12 are limited between the first clamping assembly 4 and the second clamping assembly 5, thereby achieving clamping and fixing between the two. When installing or maintaining the submersible pump 1, it is necessary to connect the outlet pipe 11 and the connecting pipe 12. First, the rotating ends of the first pressure plate 2 and the second pressure plate 3 can be lifted to align the first fixing ring 13 of the outlet pipe 11 with the second fixing ring 14 of the connecting pipe 12. Then, the first fixing ring 13 and the second fixing ring 14 are placed between the first fixing cavity and the second fixing cavity. Subsequently, the second ends of the first pressure plate 2 and the second pressure plate 3 are closed. At this time, the mirror-set first clamping component 4 will apply clamping force to the first fixing ring 13 and the second fixing ring 14, and the mirror-set second clamping component 5 will apply force simultaneously. The first clamping component 4 and the second clamping component 5 can firmly fix the first fixing ring 13 and the second fixing ring 14, thereby achieving a tight connection between the outlet pipe 11 and the connecting pipe 12. This eliminates the need to disassemble multiple bolts as with traditional flange connections, allowing a single person to complete the installation and disassembly, greatly reducing the amount of manual operation and improving the maintenance efficiency of the submersible pump 1 in humid environments such as wells and pools.

[0056] It is understandable that the mirror arrangement of the first clamping component 4 and the second clamping component 5 can be either the first clamping component 4 or two clamping components, or it can include four or more, as long as it can ensure that the clamping force on the first fixing ring 13 and the second fixing ring 14 is evenly distributed.

[0057] Combined with appendix Figure 2-4 As shown, the first clamping assembly 4 includes:

[0058] The first clamping plate 41 is disposed in the first fixing cavity;

[0059] At least one first elastic element 42 is disposed between the first clamping plate 41 and the first fixing cavity.

[0060] In this technical solution, the first clamping assembly 4 includes a first clamping plate 41 and a first elastic element 42. The first clamping plate 41 is disposed in the first fixed cavity, and its shape must be adapted to the inner wall of the first fixed cavity. The first elastic element 42 serves as the source of clamping force, and at least one is disposed between the first clamping plate 41 and the inner wall of the first fixed cavity. If it is necessary to enhance the clamping force or improve the uniformity of force distribution, two or three can be disposed. In use, when the second end of the first pressure plate 2 covers the second end of the second pressure plate 3, the first fixing ring 13 and the second fixing ring 14 are located between the first clamping plate 41. Under the action of the first elastic element 42, the first clamping plate 41 tightly clamps and fixes the first fixing ring 13 and the second fixing ring 14 from both sides.

[0061] It is understandable that a wedge-shaped chamfer is provided on the side of the first clamping plate 41 away from the first fixing cavity. The wedge-shaped chamfer is located on the opposite side of the two first clamping plates 41, which facilitates the first fixing ring 13 and the second fixing ring 14 to enter between the first clamping assembly 4.

[0062] Combined with appendix Figure 2-4 As shown, the second clamping assembly 5 includes:

[0063] The second clamping plate 51 is disposed in the second fixing cavity;

[0064] At least one second elastic element 52 is disposed between the second clamping plate 51 and the second fixing cavity.

[0065] In this technical solution, the second clamping assembly 5 includes a second clamping plate 51 and a second elastic element 52. The second clamping plate 51 is disposed in the second fixed cavity, and its shape must be adapted to the inner wall of the second fixed cavity. The second elastic element 52 serves as the source of clamping force, and at least one is disposed between the second clamping plate 51 and the inner wall of the second fixed cavity. If it is necessary to enhance the clamping force or improve the uniformity of force distribution, 2-3 elements can be disposed. In use, when the second end of the first pressure plate 2 covers the second end of the second pressure plate 3, the first fixing ring 13 and the second fixing ring 14 are located between the second clamping plate 51. Under the action of the second elastic element 52, the second clamping plate 51 tightly clamps and fixes the first fixing ring 13 and the second fixing ring 14 from both sides.

[0066] It is understandable that a wedge-shaped chamfer is provided on the side of the second clamping plate 51 away from the second fixing cavity. The wedge-shaped chamfer is located on the opposite side of the two second clamping plates 51, which facilitates the first fixing ring 13 and the second fixing ring 14 to enter between the second clamping assembly 5.

[0067] Combined with appendix Figure 2-5 As shown, a connecting component is provided between the second end of the first pressure plate 2 and the second end of the second pressure plate 3.

[0068] The connection component includes:

[0069] The first fixing block 6 is disposed on the second end of the first pressure plate 2, and at least one first fixing groove is provided in the first fixing block 6;

[0070] The second fixing block 7 is disposed on the second end of the second pressure plate 3, and at least one second fixing groove is provided in the second fixing block 7;

[0071] Connector 8 is disposed between the first fixing groove and the second fixing groove, and is used to connect the first fixing block 6 and the second fixing block 7.

[0072] In this technical solution, the first pressure plate 2 and the second pressure plate 3 are connected by a connecting component. The connecting component includes a first fixing block 6, a second fixing block 7 and a connector 8. The connector 8 can firmly lock the first pressure plate 2 and the second pressure plate 3 after they are closed, so as to prevent the first pressure plate 2 and the second pressure plate 3 from loosening due to vibration and water pressure when the submersible pump 1 is working, thereby improving the fixing stability of the first pressure plate 2 and the second pressure plate 3, and thus improving the sealing ability of the connection between the water outlet pipe 11 and the connecting pipe 12.

[0073] The first fixing block 6 is integrally formed or fixed to the outer side wall of the second end of the first pressure plate 2 by bolts. The second fixing block 7 is integrally formed or fixed to the outer side wall of the second end of the second pressure plate 3 by bolts. The first fixing block 6 has a first fixing groove, and the second fixing block 7 has a second fixing groove that matches the first fixing groove. The connecting piece 8 is installed between the first fixing groove and the second fixing groove. Its function is to fix the first fixing groove and the second fixing groove, connect the separated first fixing block 6 and the second fixing block 7, thereby restricting the opening and closing action of the first pressure plate 2 and the second pressure plate 3, which is convenient to operate.

[0074] Combined with appendix Figure 2-5 As shown, the connector 8 includes:

[0075] Rotating rod 81, the rotating rod 81 being disposed within the second fixing groove;

[0076] A connecting rod 82, the first end of which is disposed on the rotating rod 81;

[0077] A snap-fit ​​component 83 is slidably disposed on the connecting rod 82, and a snap-fit ​​groove matching the snap-fit ​​component 83 is provided on the first fixing groove;

[0078] Adjusting member 84 is disposed between the second end of the connecting rod 82 and the snap-fit ​​member 83.

[0079] In this technical solution, the connector 8 includes a rotating rod 81, a connecting rod 82, a snap-fit ​​component 83, and an adjusting component 84. The rotating rod 81 is horizontally disposed in the second fixing groove of the second fixing block 7, and its two ends are rotatably connected to the inner wall of the second fixing groove, allowing it to rotate flexibly around its own axis. The first end of the connecting rod 82 is fixedly connected to the rotating rod 81, and the second end extends above the first fixing block 6. The snap-fit ​​component 83 is installed on the connecting rod 82 and can slide along the axial direction of the connecting rod 82. The adjusting component 84 is disposed between the second end of the connecting rod 82 and the snap-fit ​​component 83, and can drive the snap-fit ​​component 83 to move on the connecting rod 82, thereby snapping the snap-fit ​​component 83 into the snap-fit ​​groove and locking and fixing the first pressure plate 2 and the second pressure plate 3. In use, when the second end of the first pressure plate 2 covers the second end of the second pressure plate 3, the first fixing block 6 and the second fixing block 7 are in contact. At this time, the connecting rod 82 is rotated upward around the rotating rod 81 so that the snap-fit ​​83 is aligned with the first fixing groove of the first fixing block 6. The thrust of the adjusting member 84 pushes the snap-fit ​​83 to move axially along the connecting rod 82. The snap-fit ​​83 is embedded in the snap-fit ​​groove, completing the locking of the first fixing block 6 and the second fixing block 7. After locking, the continuous thrust of the adjusting member 84 can ensure that the snap-fit ​​protrusion does not fall out of the snap-fit ​​groove. Even if the submersible pump 1 vibrates during operation, the connecting member 8 can be prevented from loosening. When disassembling, press the snap-fit ​​83 towards the second end of the connecting rod 82 to compress the adjusting member 84, so that the snap-fit ​​protrusion exits the snap-fit ​​groove. Then rotate the connecting rod 82 downward to lift the first pressure plate 2. The operation is convenient and there is no risk of losing parts.

[0080] It is understandable that the adjusting member 84 can be threadedly connected to the connecting rod 82. Rotating the adjusting member 84 can drive the snap-fit ​​member 83 to move up and down on the connecting rod 82, and drive the snap-fit ​​member 83 into the snap-fit ​​groove. The adjusting member 84 can also be a spring, and the elastic potential energy of the spring can drive the snap-fit ​​member 83 into the snap-fit ​​groove.

[0081] Combined with appendix Figure 2-5 As shown, the adjusting member 84 includes:

[0082] Mounting cylinder 841, the mounting cylinder 841 is disposed on the second end of the connecting rod 82;

[0083] A sealing cylinder 842 is sleeved on the mounting cylinder 841;

[0084] The third elastic element 843 is disposed between the mounting cylinder 841 and the snap-fit ​​element 83, and is located on the side of the sealing cylinder 842 away from the mounting cylinder 841.

[0085] The adjusting element 84 further includes: a pull ring 844;

[0086] A pull ring 844 is provided on the outer circumference of the sealing cylinder 842.

[0087] In this technical solution, the adjusting component 84 includes an installation cylinder 841, a sealing cylinder 842, a third elastic element 843, and a pull ring 844. The installation cylinder 841 is coaxially disposed at the second end of the connecting rod 82, and its interior is a hollow structure used to accommodate and limit the third elastic element 843. The inner diameter of the mounting cylinder 841 is matched with the outer diameter of the third elastic element 843 to ensure that the third elastic element 843 can smoothly expand and contract axially within the cylinder, avoiding uneven elastic force or jamming due to radial offset. At the same time, the length of the mounting cylinder 841 must be shorter than the natural length of the third elastic element 843 to reserve compression space for the third elastic element 843, ensuring that it can apply continuous thrust to the snap-fit ​​element 83 in its natural state. The sealing cylinder 842 is sleeved on the outside of the mounting cylinder 841, which can isolate external mud, sand, water vapor and contact with the third elastic element 843. One end of it is fitted with the mounting cylinder 841, and the other end is fixedly connected to the end face of the snap-fit ​​element 83, forming a fully enclosed space, completely enclosing the third elastic element 843 between the mounting cylinder 841 and the sealing cylinder 842. The third elastic element 843 is disposed between the mounting cylinder 841 and the snap-fit ​​element 83. When the first pressure plate 2 and the second pressure plate 3 are fixed, the sealing cylinder 842 is pushed upward, and the sealing cylinder 842 drives the snap-fit ​​element 83 to move. When the snap-fit ​​element 83 is aligned with the snap-fit ​​groove of the first fixing groove, the thrust of the third elastic element 843 can push the snap-fit ​​element 83 to automatically embed into the snap-fit ​​groove and complete the locking. When unlocking, the sealing cylinder 842 is pushed upward, and the third elastic element 843 can be compressed, providing travel space for the snap-fit ​​element 83 to disengage from the snap-fit ​​groove.

[0088] Understandably, the pull ring 844 is located on the outer circumference of the sealing cylinder 842. When unlocking, the user does not need to press the snap fastener 83 directly. Instead, the user can simply hook the pull ring 844 and pull it toward the second end of the connecting rod 82. This will cause the snap fastener 83 to compress the third elastic element 843 through the sealing cylinder 842, thus disengaging the snap fastener 83 from the snap fastener groove. This operation is convenient.

[0089] It is understandable that the snap-fit ​​component 83 can be spherical, elliptical, or square. When the snap-fit ​​component 83 is spherical, the snap-fit ​​groove is adapted to its shape, making it easy for the snap-fit ​​component 83 to enter the snap-fit ​​groove.

[0090] Combined with appendix Figure 3 As shown, an installation groove is provided inside the water outlet pipe 11, and a sealing pipe 9 is provided on the connecting pipe 12. When the water outlet pipe 11 is connected to the connecting pipe 12, the sealing pipe 9 is inserted into the installation groove.

[0091] In this technical solution, the installation groove is formed on the inner wall of the outlet pipe 11 near the connecting pipe 12, and is in the shape of an annular groove. The sealing pipe 9 of the connecting pipe 12 is coaxially fixed to the outer wall of the connecting pipe 12 near the outlet pipe 11. When the outlet pipe 11 and the connecting pipe 12 are connected, the sealing pipe 9 of the connecting pipe 12 is first aligned with the installation groove of the outlet pipe 11, so that the sealing pipe 9 is fully inserted into the installation groove. At this time, the sealing pipe 9 fits tightly with the groove wall due to the interference fit, and initially blocks the water leakage channel. Then the first pressure plate 2 and the second pressure plate 3 are closed, and the first clamping component 4 and the second clamping component 5 apply clamping force to the first fixing ring 13 and the second fixing ring 14, so that the outlet pipe 11 and the connecting pipe 12 are brought closer together, and the sealing pipe 9 is continuously squeezed in the installation groove, and the deformation is sufficient. The outer wall of the sealing pipe 9 fits the inner wall of the installation groove more closely. Even if the submersible pump 1 generates water pressure fluctuations or vibrations when it is working, it can avoid the sealing failure caused by the displacement of the sealing pipe 9.

[0092] Combined with appendix Figure 3 As shown, a sealing gasket is provided between the first fixing ring 13 and the second fixing ring 14.

[0093] Specifically, the sealing gasket is installed between the first fixing ring 13 and the second fixing ring 14. When the water outlet pipe 11 is connected to the connecting pipe 12, the sealing gasket can improve the sealing performance between the two.
