However, the existing water pump has many deficiencies:

[0003] On the one hand, whether it is an electric water pump or a hydraulic water pump, whether it is a sewage pump or a slurry pump, it has certain limitations on the diameter of the transported particulate matter, and the conveying effect of long fiber impurities or branches and the like is poor. In actual use, these impurities often wrap and block the water inlet and the pump body, greatly reducing the applicability of the water pump.

[0004] On the other hand, the conventional water pump will fix the height of the water inlet filter base when designing to ensure that the water suction port has enough flow area off the ground.

DETAILED DESCRIPTION

[0027] Example one:

[0028] As Figure 1As shown, this embodiment provides a hydraulic cutting water pump, whose structure is as follows: A hydraulic quick connector 1 is provided on the top of the hydraulic motor 2. This hydraulic quick connector 1 is used to quickly connect to an external hydraulic pipeline to provide a power source for the hydraulic motor 2. The bottom of the hydraulic motor 2 is tightly connected to the pump casing 4 through a motor flange 3 to ensure the sealing and stability of the connection and prevent water leakage or power transmission obstruction. An impeller 8 is installed inside the pump casing 4. The impeller 8 is firmly fixed to the output end of the hydraulic motor 2 by fixing bolts 7, so that the hydraulic motor 2 can efficiently drive the impeller 8 to rotate, realizing the suction and transportation of liquid. A cutting component 6 is provided at the bottom of the pump casing 4.

[0029] When the hydraulic cutting water pump is working, an external hydraulic source supplies high-pressure hydraulic oil to the hydraulic motor 2 through a hydraulic quick connector 1, driving the hydraulic motor 2 to rotate, which in turn drives the impeller 8 to rotate at high speed. At this time, a negative pressure is formed near the water inlet 41 at the bottom of the pump casing 4. Under the action of the pressure difference, the surrounding water is drawn into the pump casing 4. As the impeller 8 continues to rotate, the water is accelerated and discharged from the water outlet 42 on the side of the pump casing 4, completing the drainage operation. At the same time, the rotation of the impeller 8 drives the debris to rotate, and when it passes the cutting piece 6, it cuts the debris to prevent the debris from getting tangled and blocking the water inlet. The fixing bolt 7 is sunk into the impeller body to prevent debris from getting tangled during rotation. The impeller can be directly installed on the output end of the hydraulic motor 2 without complicated sealing, simplifying the structure and reducing the risk of failure. Furthermore, when encountering the common failure condition of stall, thanks to the safety valve mechanism of the hydraulic system, the hydraulic motor can remain unharmed and avoid damage due to overload.

[0030] Example 2:

[0031] like Figures 1-3 As shown, based on Embodiment 1, the cutting component includes an integral blade 62 and a cutting blade 61. The integral blade 62 is located at the bottom of the inlet end face of the impeller 8, and the cutting blade 61 is fixedly installed at the bottom of the pump casing 4. When the integral blade 62 rotates, it is tangential to the cutting blade 61. When long fibrous debris or similar debris such as branches enter the bottom of the pump casing 4 near the inlet 41 with the water flow during pump operation, the high-speed rotating impeller 8 drives the integral blade 62 to rotate synchronously. The integral blade 62 and the cutting blade 61 on the cutting component 6 cooperate with each other, cutting the debris like scissors. Since there are several cutting blades 61, and these blades are evenly distributed along the axis of the impeller 8, the uniformity and reliability of the cutting action are ensured, effectively preventing debris from entangled and clogging the inlet and pump body, thus improving the applicability of the pump to complex drainage environments.

[0032] For example, in urban flood drainage scenarios, water often contains debris such as plastic bags and tree branches. This hydraulic cutting water pump, with its unique cutting structure, can successfully shred these debris, allowing them to pass smoothly through the pump body with the water flow, without affecting the continuous drainage operation.

[0033] Example three:

[0034] As Figures 4-5 shown, based on example two, the bottom of the pump housing 4 is provided with a water inlet 41, the side is provided with a water outlet 42, and the bottom is also provided with an adjustable filter base 5. The adjustable filter base 5 includes an upper base 51 which is fixedly installed on the bottom of the pump housing 4 near the water inlet 41. The adjustable filter base 5 also includes a lower base 52 which is detachably connected to the upper base 51 by quick release screws 53.

[0035] In the early stage of emergency drainage operation, when the water depth is large, the lower base 52 can be installed below the upper base 51 by quick release screws 53 to increase the height of the filter base, ensure that the water suction port has enough flow area from the ground, and enable the water pump to efficiently suck and drain water. In the last stage of drainage operation, when the water level is low, the lower base 52 can be quickly removed to reduce the height of the filter base and drain as much water as possible to reduce the workload of subsequent water cleaning. For example, in the underground garage drainage operation, when there is a large amount of water, the complete adjustable filter base ensures smooth drainage, and when there is a small amount of water left, the lower base 52 can be removed to drain the water.

[0036] Example four:

[0037] As Figure 1 shown, according to example one, the top of the hydraulic motor 2 is provided with an eye 10. In different scenarios such as urban waterlogging and field drainage, when the water pump needs to be frequently moved, a rope or other tool can be used to pass through the eye 10 to conveniently hoist the water pump to the appropriate location. For example, in field drainage operation, the terrain around the operation site is complex and vehicles cannot directly reach the site. Workers can use a helicopter or crane to hoist the water pump to the water accumulation area by means of the eye 10, greatly improving the mobility of the water pump and meeting the needs of high-mobility drainage operation.

[0038] Example five:

[0039] As Figure 1 shown, based on example three, the water outlet 42 is provided with a connecting joint 9. In actual drainage operation, according to different drainage needs and drainage pipeline configurations, the connecting joint 9 can be easily connected with various specifications of drainage hoses or hard pipes. For example, when draining water in urban waterlogging, the water pumped out by the water pump needs to be guided to a distant drainage channel. By means of the connecting joint 9, long-distance drainage hoses can be quickly connected to ensure smooth drainage path and improve drainage efficiency.
