[0002] A drainage pump is a special equipment used to remove or transfer water. It is widely used in various occasions, such as drainage systems, sewage treatment, construction sites, basement drainage and farmland irrigation. The drainage pump is driven by an electric motor or a diesel engine to draw water or other liquids into the pump body, and then the rotation of the impeller or propeller inside the pump body generates centrifugal force or driving force to discharge the liquid from the pump body.

[0003] According to a disclosed submersible pump for foundation pit drainage for hydropower engineering (publication number: CN 215596013U), it includes a submersible pump body, the lower end of the submersible pump body is fixedly connected to a base, the lower end of the base is fixedly installed with a filter screen cover, the surface of the filter screen cover is provided with a cleaning mechanism, the cleaning mechanism includes a mounting seat, the mounting seat is slidably connected to the bottom of the base through a sliding mechanism, an annular cleaning brush is arranged in the mounting seat, and the annular cleaning brush is fixed to the mounting seat through a limiting mechanism, the sliding mechanism includes a motor, the motor is fixedly installed on the upper end surface of the front side of the base, the output end of the motor is fixedly connected to a screw, the rear side of the base is fixedly connected to a guide rod, the middle part of the front and rear side walls of the mounting seat is fixedly connected to a slider, and the front slider is threadedly connected to the screw. In the above application, a submersible pump for foundation pit drainage for hydropower engineering directly drains water by immersing the pump body in accumulated water.

[0011] (1) The present application can achieve a good sealing effect through the sealing ring at the bottom end of the sealing frame. When the fixing block at the bottom end of the sealing ring enters the limiting groove, the sealing frame is then rotated clockwise so that the limiting rod enters the slot to complete the fixation. Subsequently, the sliding frame is pushed so that the push rod pushes the limiting rod out of the slot, and the sealing frame is rotated counterclockwise to complete the disassembly.

[0012] (2) The present application rotates the bolt counterclockwise to make it leave the threaded hole, thereby releasing the fixed state of the upper connecting member, and then rotates the upper connecting member clockwise to make it threadedly connected with the lower connecting member, and finally cooperates with the sealing gasket to further achieve a sealing effect.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Embodiment 1

[0024] See also Figure 1-8 A foundation pit drainage water pump with good sealing performance comprises a pump body 1 and a sealing frame 3. The bottom end of the pump body 1 is fixedly connected with a base 2. The bottom end of the sealing frame 3 is fixedly connected with a sealing ring 4. The sealing ring 4 is fixedly connected with the bottom end of the sealing frame 3. The material used for the sealing ring 4 is water-swelling rubber. The water-swelling rubber is a special rubber material. It has the property of swelling when absorbing water. When the water-swelling rubber contacts water or humidity, it absorbs moisture and swells, thereby changing its volume and shape. The bottom end of the sealing frame 3 is fixedly connected with a fixing mechanism 5.

[0025] The fixing mechanism 5 includes a fixing block 51, which is an L-shaped structure, and the side close to the pump body 1 and the opposite side are arc-edge structures concentric with the sealing frame 3, and the bottom end of the sealing ring 4 is fixedly connected to the sealing ring, and a limiting rod 52 is slidably connected in the fixing block 51, and the bottom end of the limiting rod 52 is fixedly connected to a spring 53. A limiting groove 54 is provided at the top of the base 2, and the limiting groove 54 provided at the top of the base 2 matches the size of the fixing block 51, so that when the sealing frame 3 is sleeved on the pump body 1, the fixing block 51 can enter the limiting groove 54, and a card slot 55 is provided in the base 2. A sliding frame 56 is slidably connected to the side of the base 2, and a push rod 57 is fixedly connected to the side of the sliding frame 56. One end of the push rod 57 passes through the base 2 and The slider is fixedly connected, and the other end is slidably connected to it in the slot 55. The bottom end of the push rod 57 is fixedly connected to a spring 2 58, and the bottom end of the spring 2 58 is fixedly connected to a fixing seat 59. The fixing seat 59 is fixedly connected to it on the side of the base 2. One end of the other spring 1 53 is fixedly connected to the limiting rod 52, and the other end is fixedly connected to it in the fixing block 51. The present application can achieve a good sealing effect through the sealing ring 4 at the bottom end of the sealing frame 3. When the fixing block 51 at the bottom end of the sealing ring 3 enters the limiting groove 54, the sealing frame 3 is then rotated clockwise so that the limiting rod 52 enters the slot 55 to complete the fixation. Subsequently, the sliding frame 56 is pushed so that the push rod 57 pushes the limiting rod 52 out of the slot 55. The sealing frame 3 can be disassembled by rotating counterclockwise.

[0026] When the present embodiment is used, the sealing frame 3 is sleeved toward the pump body 1, and the fixing block 51 at the bottom of the sealing frame 3 is aligned with the limiting groove 54 opened at the top of the base 2. When the outer frame 3 is sleeved on the pump body 1, the fixing blocks 51 on both sides enter the limiting groove 54, and the sealing ring 4 at the bottom of the sealing frame 3 also enters the preset groove of the base 2, which plays a sealing effect. When the fixing block 51 enters the limiting groove 54, the sealing frame 3 is rotated clockwise so that the limiting rod 52 at the top of the fixing block 51 is restricted by the edge of the limiting groove 54 so as to enter the fixing block 51, and the compression spring 53 is compressed. As the fixing block 51 rotates, the limiting rod 52 eventually reaches the front end of the card slot 55. At this time, affected by the elastic force of the spring 1 53, the limiting rod 52 is pushed into the card slot 55 to fix the sealing frame 3. If the sealing frame 3 needs to be removed later, the sliding frame 56 is pushed toward the direction of the fixing seat 59 so that it drives the push rod 57 to move downward and compress the spring 2 58. At the same time, the push rod 57 pushes the limiting rod 52 out of the card slot 55 so that it enters the fixing block 51. At this time, the sealing frame 3 can be taken out by rotating counterclockwise, and then the sliding frame 56 and the push rod 57 are reset by the elastic force of the spring 2 58.

[0027] Embodiment 2

[0028] See also Figure 1-3, a sealing mechanism is added on the basis of the first embodiment, and the sealing mechanism includes an upper connecting member 6, which is slidably connected to the side of the sealing frame 3, and the top of the upper connecting rod 6 is fixedly connected to a fixing frame 7, and a bolt 8 is rotatably connected in the fixing frame 7. A head threaded hole 9 is opened on the side of the sealing frame 3, and a lower connecting member 10 is fixedly connected to the side of the base 2. A sealing gasket 11 is fixedly connected to the side of the sealing frame 3. The material used for the sealing gasket 11 is also water-expandable rubber. The thickness of the sealing gasket 11 is consistent with the thickness of the lower connecting member 10, so that the bolt 8 is threadedly connected to it in the threaded hole 9. When the upper connecting member 6 and the lower connecting member 10 are threadedly connected to the bottom end, the sealing gasket 11 can play a further sealing role. In this application, the bolt 8 is rotated counterclockwise to make it leave the threaded hole 9, thereby releasing the fixed state of the upper connecting member 6, and then the upper connecting member 6 is rotated clockwise to make it threadedly connected to the lower connecting member 10, and finally cooperates with the sealing gasket 11 to further play a sealing effect.

[0029] When in use, on the basis of Example 1, after the fixing mechanism 5 is fixed, the bolt 8 on the side of the fixing frame 7 is rotated counterclockwise so that it leaves the threaded hole 9 opened on the side of the sealing frame 3. At this time, the fixed state of the upper connecting rod is released, and then the upper connecting piece 6 is rotated clockwise so that it is threadedly connected with the lower connecting piece 10. As the upper connecting piece 6 rotates, the upper connecting piece 6 and the lower connecting piece 10 are finally firmly fixed. A sealing gasket 11 is provided on the outside of the sealing frame 3. When the upper connecting piece 6 and the lower connecting piece 10 are threadedly connected, the sealing gasket 11 is completely fitted with the upper connecting piece 6. If the sealing frame 3 needs to be removed later, the upper connecting piece 6 can be rotated counterclockwise to contact the fixed state. Through the threaded connection between the upper connecting piece 6 and the lower connecting piece 10, the pump body 1 can be further sealed, further reducing the possibility of water seepage during operation in the foundation pit.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
