DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Reference Figures 1 to 6As shown, this embodiment provides an engineering drainage pump with an anti-clogging structure, including a pump casing 2, an impeller 15 is rotatably connected inside the pump casing 2, the central axis of the impeller 15 is connected to the output end of the driving component 1, the driving component 1 and the pump casing 2 are installed together through a connecting bracket 101, and a water inlet 201 and a water outlet 202 are provided on the pump casing 2, the water inlet 201 is connected to the water inlet at the center of the impeller 15, a crushing structure is installed at the water outlet 202, and a secondary delivery structure is installed at the water outlet 202, and the crushing structure and the secondary delivery structure are transmission-connected to the driving component 1.

[0027] The present invention provides a crushing structure at the water inlet 201, so that the debris contained in the water entering the pump casing 2 can be crushed in advance, and then sent to the outside through the water inlet 201 as the impeller 15 rotates, and a secondary delivery structure is provided at the water outlet 202 to effectively avoid the crushed debris from getting stuck at the water outlet 202 to form a blockage, and the crushing structure, the secondary delivery structure and the operation of the pump body share a driving component 1, which reduces and simplifies the structure, making the drainage pump run more stably, and the crushing structure and the secondary delivery structure have a certain water flow driving effect during operation, which can further prevent the drainage pump from being blocked.

[0028] A further optimized solution is that the driving component 1 is a motor, the output shaft of the motor passes through the connecting bracket 101, the pump casing 2 and is connected to the central axis of the impeller 15, the connecting bracket 101 is internally rotatably connected with a driving gear disc 102, the driving gear disc 102 is connected to the output shaft of the motor, and the crushing structure and the secondary delivery structure are meshed with the driving gear disc 102.

[0029] A further optimized solution is provided, wherein the crushing structure includes a first crushing roller 11 and a second crushing roller 12 which are rotatably connected to the water inlet 201, one end of the first crushing roller 11 and the second crushing roller 12 pass through the pump casing 2, the end of the first crushing roller 11 located on the outside is axially connected to a first gear 3, the end of the second crushing roller 12 located on the outside is axially connected to a second gear 4, the first gear 3 and the second gear 4 are meshed with each other, the second gear 4 is meshed with a third gear 5, the third gear 5 is meshed with a driving toothed disc 102, and the third gear 5 is rotatably connected to the connecting bracket 101.

[0030] The arrangement of the first gear 3, the second gear 4, and the third gear 5 can enable the active toothed disc 102 to drive the first crushing roller 11 and the second crushing roller 12 to rotate. After the drainage pump is started, the active toothed disc 102 will rotate along with the operation of the motor. At this time, the first crushing roller 11 and the second crushing roller 12 also start to rotate synchronously. When water enters between the pump casing 2, the debris contained therein is crushed by the first crushing roller 11 and the second crushing roller 12 before entering the pump casing 2. At this time, the particles of the debris are relatively small and can be discharged along with the rotation of the impeller 15. Driving the first crushing roller 11 and the second crushing roller 12 by gear transmission simplifies the structure of the filter cleaning method in the prior art, making the drainage pump more stable during operation.

[0031] According to a further optimization scheme, the third gear 5 can move axially on the connecting bracket 101 , and a first linkage motor 6 is installed on the connecting bracket 101 , and the first linkage motor 6 is a starter.

[0032] The start and stop of the first linkage motor 6 can drive the meshing state between the third gear 5 and the second gear 4, and it can be determined whether crushing is required at the water inlet 201 according to the actual operation situation.

[0033] A further optimized solution is provided, wherein the secondary delivery structure comprises a first outlet conveying gear 13 and a second outlet conveying gear 14 which are rotatably connected to the water outlet 202, one end of the first outlet conveying gear 13 and the second outlet conveying gear 14 pass through the pump casing 2, the end of the first outlet conveying gear 13 located on the outside is axially connected to a fourth gear 7, the end of the second outlet conveying gear 14 located on the outside is axially connected to a fifth gear 8, the fourth gear 7 and the fifth gear 8 are meshed with each other, the fifth gear 8 is meshed with a sixth gear 9, the sixth gear 9 is meshed with a driving toothed disc 102, and the sixth gear 9 is rotatably connected to the connecting bracket 101.

[0034] The arrangement of the fourth gear 7, the fifth gear 8, and the sixth gear 9 can enable the active gear plate 102 to drive the first outlet conveying gear 13 and the second outlet conveying gear 14 to rotate. After the drainage pump is started, the active gear plate 102 will rotate along with the operation of the motor. At this time, the first outlet conveying gear 13 and the second outlet conveying gear 14 also start to rotate synchronously. When discharged from the pump housing 2, debris will gather at the throat of the outlet, and the hard water flow will be discharged. The arrangement of the first outlet conveying gear 13 and the second outlet conveying gear 14 can enable both to discharge the water in the pump housing 2, and drive the first outlet conveying gear 13 and the second outlet conveying gear 14 by gear transmission, which simplifies the structure of the filter cleaning method in the prior art and makes the drainage pump more stable during operation.

[0035] According to a further optimization scheme, the sixth gear 9 can move axially on the connecting bracket 101 , and a second linkage motor 10 is mounted on the connecting bracket 101 , and the second linkage motor 10 is a starter.

[0036] The start and stop of the second linkage motor 10 can adjust the meshing state of the sixth gear 9 and the fifth gear 8, and then according to the actual use situation, it can be adjusted whether to force drainage.

[0037] According to a further optimization scheme, both the first crushing roller 11 and the second crushing roller 12 include conveying teeth 1101 and crushing teeth 1201 that are staggered, and the thickness of the conveying teeth 1101 and the crushing teeth 1201 are the same.

[0038] According to a further optimization scheme, the crushing teeth 1201 of the first crushing roller 11 are located between the two crushing teeth 1201 of the second crushing roller 12 , and the outer contour of the crushing teeth 1201 on the first crushing roller 11 is circumscribed with the outer contour of the conveying teeth 1101 on the second crushing roller 12 .

[0039] The crushing teeth 1201 on the first crushing roller 11 and the conveying teeth 1101 on the second crushing roller 12 are arranged in this way to form an operating state similar to a gear pump. Similarly, the conveying teeth 1101 on the second crushing roller 12 and the conveying teeth 1101 on the first crushing roller 11 form an operating state similar to a gear pump. In this state, although some debris may affect the entry of water flow, there is a situation of crushing and conveying water flow between them, thereby ensuring that the water flow can smoothly enter the pump housing 2 and avoid clogging of the drainage pump.
