Description

Technical Field

[0001] This invention relates to the field of booster pumps, and more specifically to a booster pump. Background Technology

[0002] A booster pump is a common type of pressure-boosting device used to increase the pressure of liquids or gases to meet operational requirements. Existing booster pumps typically use an electric motor as a power source, driving the liquid or gas flow by rotating an impeller to achieve the desired pressure. Generally, the input shaft of a booster pump, which connects to the output shaft of the electric motor, is sealed at the connection between the input shaft and the pump housing to prevent leakage. However, after prolonged use, this sealing device may fail, allowing leakage. Furthermore, damage to the sealing device is not easily detected by the operator, potentially causing liquid to drip onto nearby non-waterproof components and damage them. Summary of the Invention

[0023] The present application will be further described below in conjunction with the accompanying drawings and examples: Figures 1-8

[0024] A booster pump comprises a booster pump body 1, a support 2 is fixedly arranged outside the booster pump body 1, an electric motor 3 is fixedly arranged on the support 2, a connecting device 4 is arranged between the output shaft of the electric motor and the input shaft of the booster pump body 1, a detection device 5 for detecting water leakage is arranged outside the booster pump body 1, and the detection device 5 is located below the input shaft of the booster pump body 1.

[0025] The connecting device 4 comprises a movable sleeve 30 which is movably sleeved on the output shaft of the electric motor 3, the outer surface of the output shaft of the electric motor 3 is provided with a limiting groove 31, the inner wall of the movable sleeve 30 is fixedly provided with a limiting block 32 which is located in the limiting groove 31, one end of the output shaft of the electric motor 3 and the bottom of the movable sleeve 30 are fixedly provided with a spring 33, one end of the input shaft of the booster pump body 1 is provided with a spline groove 34, and the outer surface of the movable sleeve 30 is fixedly provided with a spline 35 which is located in the spline groove 34.

[0026] ​​The detection device 5 comprises a liquid storage shell 50 fixedly arranged outside the booster pump body 1. The top of the liquid storage shell 50 is provided with a liquid inlet 51 in communication with the liquid storage shell 50. The top of the liquid storage shell 50 is provided with a movable groove 52 in communication with the liquid storage shell 50. The movable groove 52 is provided with a reciprocating movable block 53. The lower end of the movable block 53 is fixedly provided with a buoyancy ball 54. The upper end of the buoyancy ball 54 is fixedly provided with a push position block 55. The outer surface of the movable sleeve 30 is provided with an annular groove 56. The annular groove 56 is rotatably provided with a conical block 57. The annular groove and the conical block are rotatably arranged to allow the push position block 55 to push against the conical block 57, which does not affect the continuous rotation of the output shaft driven by the motor, thereby avoiding the output shaft driving the conical block 57 to rotate at high speed when the push position block 55 is pushed against the conical block 57, which causes the buoyancy ball 44 to be damaged due to excessive wear.

[0027] The motor 3 is started to drive the output shaft of the motor 3 to rotate. The output shaft of the motor 3 drives the movable sleeve 30 to rotate through the cooperation of the limiting block 32 and the limiting groove 31. The movable sleeve 30 drives the input shaft of the booster pump body 1 to rotate through the cooperation of the spline 35 and the spline groove 34, so that the booster pump body enters the working state. When liquid seeps through the gap between the input shaft of the booster pump body and the booster pump shell, it enters the liquid storage shell 50 through the liquid inlet 51. The increase of the liquid in the liquid storage shell 50 gradually drives the buoyancy ball 54 to move upwards. The buoyancy ball 54 drives the movable block 53 and the push position block 55 to move upwards to push the conical block 57 away from the input shaft of the booster pump body 1, so that the spline 35 is separated from the spline groove 34, and the booster pump body can stop working to deliver liquid.

[0028] The movable block 53 is provided with an auxiliary device on both sides. The auxiliary device comprises a support plate 100 fixedly arranged on the inner wall of the liquid storage shell 50. The support plate 100 is provided with a moving groove 101. The moving groove 101 is provided with a reciprocating top rod 102. The bottom end of the top rod 102 and the bottom of the moving groove 101 are fixedly provided with a return spring 103. One side of the movable block 53 is fixedly provided with a pressing plate 104 for cooperation with the top rod 102. The upper surface of the support plate 100 is rotatably provided with a rotating shaft 105. The rotating shaft 105 is fixedly provided with a rotating plate 106. The outer surface of the movable block 53 is fixedly provided with a mounting plate 107. The top of the mounting plate 107 is fixedly provided with a moving rod 307 for cooperation with the rotating plate 106.

[0029] When the movable block 53 moves upward, the moving rod 307 will move upward to push the support plate 106 to rotate, so that the support plate 106 leaves the upper surface of the top rod 102, and the top rod 102 can move upward under the elastic force of the return spring 103 to push the pressing plate 104 upward. By pushing the pressing plate 104, the movable block 55 can be pushed away from the input shaft of the booster pump body, so that the floating ball can be pushed away from the conical block 57 by the liquid, and the pushing force is sufficient, so that the booster pump can smoothly leave the working state to avoid continuous water leakage to damage the non-waterproof components outside.

[0030] The top of the top rod 102 is provided with a plurality of three-quarter ball grooves 150, and a freely rolling ball 151 is arranged in each three-quarter ball groove 150. The arrangement of the ball 151 can reduce the friction between the 106 and the 102, so that the 106 can be smoothly moved away from the 102.

[0031] The internal structure of the booster pump body is a prior art, and the structure will not be described again.

[0032] The side surface of the rotating plate 106 is provided with an inclined surface 155, and the top of the moving rod 307 is provided with a hemispherical shape.

[0033] Working principle: the motor 3 is started to drive the output shaft of the motor 3 to rotate. The output shaft of the motor 3 can drive the movable sleeve 30 to rotate through the cooperation of the limiting block 32 and the limiting groove 31. The movable sleeve 30 drives the input shaft of the booster pump body 1 to rotate through the cooperation of the spline 35 and the spline groove 34, so that the booster pump body enters the working state. When the liquid seeps through the gap between the input shaft of the booster pump body and the booster pump shell and enters the liquid storage shell 50 through the liquid inlet 51, the liquid in the liquid storage shell 50 increases, which gradually drives the floating ball 54 to move upward, and the floating ball 54 drives the movable block 53 and the push block 55 to move upward to push the conical block 57 away from the input shaft of the booster pump body 1, so that the spline 35 leaves the spline groove 34, and the booster pump body can stop working to deliver liquid. At the same time, when the movable block 53 moves upward, the moving rod 307 will move upward to push the support plate 106 to rotate, so that the support plate 106 leaves the upper surface of the top rod 102, and the top rod 102 can move upward under the elastic force of the return spring 103 to push the pressing plate 104 upward. By pushing the pressing plate 104, the movable block 55 can be pushed away from the input shaft of the booster pump body, so that the floating ball can be pushed away from the conical block 57 by the liquid, and the pushing force is sufficient, so that the booster pump can smoothly leave the working state to avoid continuous water leakage to damage the non-waterproof components outside.

[0034] The embodiments of the present application have been disclosed with the best mode, and are not limited thereto. It will be obvious to those skilled in the art that various changes and modifications can be made thereto without departing from the spirit of the present application, and it is intended to cover within the scope of the present application any and all such changes and modifications.
