Description

Technical Field

[0001] The present invention relates to the technical field of construction water removal, and particularly to a modified device for the water inlet of a self-priming centrifugal pump. Background Art

[0002] During construction, a large amount of water is required, and a large amount of accumulated water is likely to be generated at the construction site. The area of the accumulated water is large, but the depth of the accumulated water is relatively shallow. When using a self-priming centrifugal pump to pump water, it is not easy to pump out the sewage.

[0003] After retrieval, for example, the patent with the patent number CN211596931U discloses a green water extraction device based on a construction site, including a construction site pumping and water storage structure, a fan blade driving structure, and a fan air cooling structure. The construction site pumping and water storage structure includes a construction site building shed and a water intake pump. A water storage tank is provided at the top of the construction site building shed, and a fan blade driving structure is fixed to one side of the construction site building shed. One end of the water intake pump is provided with a water delivery pipe, and the end of the water delivery pipe is connected to the fan air cooling structure. The utility model can utilize the low-temperature characteristics of the water extracted during the construction process to cool the construction shed or temporary housing within the construction site and update the air, avoiding the long-term use of air conditioners in the construction site during summer. Moreover, the driving of the cooling fan can adopt electric energy and the potential energy of the extracted water according to the actual situation, making the energy consumption of the construction site more green and environmentally friendly, reducing the electric energy consumption of the construction site, and having stronger practicability.

[0004] For another example, the patent with the patent number CN211370808U discloses a new type of construction site pumping device, which includes a water pump. The outlet end of the water pump is connected to a water delivery pipe, and the inlet end of the water pump is connected to a water inlet pipe made of a flexible material. A floating plate is provided at one end of the water inlet pipe away from the water pump, and the water inlet pipe passes through the floating plate and is relatively fixed to it. The utility model has the advantages of simple operation and long service life of the water pump.

[0005] However, the existing modified devices for the water inlet of self-priming centrifugal pumps generally have large pipe orifice structures, generally do not have structures for facilitating the scraping of sediment at the water inlet, cannot prevent sediment from blocking the water inlet position, cannot improve the pumping efficiency in shallow water areas, do not have structures that can prevent the water inlet pipe from folding and affecting the pumping efficiency, do not have structures that can facilitate the movement of the device in shallow water areas, and do not have structures for adjusting the bending angle of the water pipe.

[0006] Therefore, it does not meet the existing requirements, and for this reason, we propose a modified device for the water inlet of a self-priming centrifugal pump. Summary of the Invention

[0017] (III) Beneficial effects

[0018] The present invention provides a modified device for the water inlet of a self-priming centrifugal pump. By setting a support and cleaning structure and cooperating with a mud scraping plate, when there is too much sediment at the bottom of the bifurcated square pipe, the three-phase asynchronous motor can be started to rotate the horizontal shaft rod. Through the rotation of the horizontal shaft rod, the bevel gear set A coaxially connected with it can drive the vertical rod to rotate, and the transmission gear coaxially connected with the vertical rod can rotate. Through the rotation of the transmission gear, the engaged tooth part can be driven to move horizontally, so that the mud scraping plate moves horizontally back and forth to scrape the sediment at the bottom of the bifurcated square pipe, which can prevent the sediment from blocking the water inlet position and improve the pumping efficiency in the shallow water area.

[0019] Secondly, with the fixed adjustment structure, the user can hold the push grip with both hands and lift it upward. After the base is separated from the ground contact, the front-end roller of the device touches the ground, enabling convenient movement of the device in the shallow water area; with the adjustable nozzle structure, the user can rotate the adjustment knob. This causes the bevel gear set B to drive the reciprocating lead screw to rotate. As the reciprocating lead screw rotates, the ball nut seat connected to it moves vertically, which can change the horizontal position of the limit hoop A. By cooperating with the limit hoop, the water inlet pipe can be at a relatively gentle bending angle, facilitating water intake.

[0020] Furthermore, with the setting of the limit hoop A, by placing the water inlet pipe inside the limit hoop A, the user can press the clamping plate. Due to the lever principle, the left side of the clamping plate will tilt upward, which can fasten the movable flap and the fixed flap. After releasing the clamping plate, the right side spring of the clamping plate can lift it, causing the left side of the clamping plate to buckle inward. This allows the left end of the clamping plate to fit the inclined groove. Through the spring pressure, it can prevent the clamp from opening randomly and can provide good fixation for the water inlet pipe; by cooperating the limit hoop A and the limit hoop B, it can prevent the water inlet pipe from folding and affecting the pumping efficiency.

[0039] Working principle:

[0040] When the device is in use, first fix the water inlet pipe 2 to the water inlet of the self-priming centrifugal pump 1 using a flange. Pass the water inlet pipe 2 through the limit hoop A7 and the limit hoop B8, and place the water inlet pipe 2 inside the limit hoop A7. By pressing the clamping plate 704, the left side of the clamping plate 704 can be lifted by the lever principle, and the movable valve 702 can be buckled with the fixed valve 701.

Start the self-priming centrifugal pump 1 to pump the wastewater in the shallow water area through the pumping holes 403 at the bottom of the bifurcated square pipe 402. When there is too much sediment at the bottom of the bifurcated square pipe 402, start the three-phase asynchronous motor 507 to rotate the horizontal shaft rod 503.
