Description

Dirt blocking pump body structure and water pump

Technical Field

The application relates to the technical field of fluid conveying equipment, in particular to a dirt blocking pump body structure and a water pump.

Background

Pumps are machines that deliver or pressurize fluids. When the pump is used, the whole unit is immersed into water for working, and can be applied to domestic water, mine rescue, industrial cooling, farm irrigation, seawater lifting and ship load adjustment, and fountain landscapes.

When the water pump pumps water, the water at the bottom of the pool or the container cannot be pumped out, and when the liquid level drops to a certain height, the water pump cannot absorb water normally. When the water pump works, the water inlet of the water pump cannot be directly downwards placed at the water bottom, and when the water pump is placed at other angles, the water inlet of the water pump can cause that more water remained at the bottom of the pool or the container cannot be pumped away.

Detailed Description

The following are specific embodiments of the present application and the technical solutions of the present application are further described with reference to the accompanying drawings, but the present application is not limited to these embodiments. In the following description, specific details such as specific configurations and components are provided merely to facilitate a thorough understanding of embodiments of the present application. It will therefore be apparent to those skilled in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the application. In addition, descriptions of well-known functions and constructions are omitted for clarity and conciseness.

In addition, embodiments and features of embodiments in the present application may be combined with each other without conflict.

Referring to fig. 1 to 5, an embodiment of the present application provides a trash pump body structure, including a pump housing 10 and a trash structure 20. Wherein, the bottom of the pump housing 10 is provided with a water inlet 11. In operation of the pump, water in the tank or container is drawn into the pump housing 10 from the water inlet.

In the prior art, a water pump is placed in a tank or container, and as the water pump operates, water in the tank or container is drawn. The water pump comprises an impeller and a motor for driving the impeller to rotate, and when the motor drives the impeller to rotate, the water inlet of the pump body starts to feed water. When the water pump works, the water inlet of the water pump cannot be directly downwards placed at the water bottom, and when the water pump is placed at other angles, the water inlet of the water pump can cause that more water remained at the bottom of the pool or the container cannot be pumped away. For example, in a state where the water pump is horizontally placed, when the water level is lowered to the water inlet position, the water pump cannot feed water. In addition, when the pump is placed in water to pump water, impurities in the water can be sucked, and the operation of the pump is adversely affected. In severe cases, larger debris may block the normal rotation of the water pump impeller, damaging equipment, and thereby increasing maintenance costs.

In this application, a dirt blocking structure 20 is provided near the water inlet at the bottom of the pump housing 10. The trash rack 20 comprises a plurality of trash racks 21 circumferentially arranged along the water inlet 11; the trash rack 21 is movably connected with the pump housing 10. The trash rack 21 can be unfolded and adjusted to the first state position around the water inlet 11 so as to prop up the pump housing 10 to suspend the water inlet 11. The trash rack 21 can be folded towards the middle of the water inlet 11 and adjusted to the second state position so as to form a filtering structure covering the water inlet 11.

Referring to fig. 3, when the water inlet of the water pump is placed downwards, the trash rack is unfolded and adjusted to the first state position around the water inlet, the trash rack supports the pump housing to suspend the water inlet, and in this state, water can enter the pump body from the periphery of the water inlet. The height of the water inlet 11 from the water bottom is determined by the supporting height of the trash rack, so that the height of the water inlet from the water bottom can be made as low as possible, and the water pump can pump the water level in the pool or the container to be lower, and the residual water in the pool or the container is less. In addition, the trash rack which is unfolded around the water inlet can also be used for filtering and blocking sundries in water.

Referring to fig. 2, when the trash rack is not required to be supported, the trash rack can be folded towards the middle of the water inlet and adjusted to the second state position, the trash rack forms a filtering structure covering the water inlet, so that impurity filtering is performed on the inflow water of the water inlet.

It will be appreciated that the stability of the first and second condition positions of the grate 21 is sufficient to meet normal functional requirements.

In some embodiments, the trash racks 21 can be removably attached to one another by connectors in the second condition position. When the trash racks are folded towards the middle of the water inlet and adjusted to the second state, the trash racks 21 are detachably connected together, and the trash racks are limited. In some embodiments, the connection between the pickles is a pin or threaded connection. Specifically, when the trash rack is adjusted to the second state position, the trash rack is connected together through inserting the bolts, and when the bolts are removed, the trash rack can be freely adjusted.

Referring to fig. 1-3, in some embodiments, the pump housing 10 forms a horn-like structure 12 at the location of the water inlet 11; the trash rack 21 is connected to one side of the inner surface of the trumpet-shaped structure 12. Referring to fig. 1, the adjustment range S of the trash rack 21 is adjustable to a second state position shown in fig. 2 or a first state position shown in fig. 3. In the first state position, the trash rack 21 extends out of the water inlet 11 from the inner surface side of the horn-shaped structure 12, and is limited to the first state position by the shape of the horn-shaped structure 12, namely, is obliquely arranged around the water inlet 11.

In some embodiments, the trash rack 21 is hinged to the pump housing 10. The trash rack 21 can rotate around the hinge part to adjust the position.

Referring to fig. 4, the trash rack 21 is fan-shaped. Along the circumference of the water inlet 11, four trash racks 21 are fixed on the horn-shaped structure 12, and when the trash racks 21 are adjusted to the second state position, the whole trash rack forms a filtering structure covering the water inlet, so that impurity filtering is carried out on the inflow water of the water inlet. It should be appreciated that the number of the dirt barriers 21 comprised by the dirt barrier structure may be 2,3,4, … …, n.

Specifically, the trash rack 21 is a filtering structure, and has a filtering function, and the specific structural form is not limited herein, and may specifically be a grid structure with a grid shape or other filtering structures with filtering functions.

Referring to fig. 5, the trash pump body structure is installed at the bottom of the water pump. In some embodiments, the water pump includes an impeller and a power source inside, and water around the water inlet is drawn into the pump housing as the power source drives the impeller to rotate.

In this application, the pump housing is circumferentially arranged with a plurality of trash racks along the water inlet. When the water inlet of the pump body is placed downwards, the trash rack can be unfolded and adjusted to the first state position around the water inlet, and the pump housing is supported to enable the water inlet to be suspended, so that the water pump can absorb water smoothly. The water inlet of the water pump faces downwards, and the height of the water inlet from the water bottom can be as low as possible, so that the water pump can pump the water level in the pool or the container to be lower, and the residual water in the pool or the container is less. In addition, the trash rack which is unfolded around the water inlet can also be used for filtering and blocking sundries in water. When the trash rack is folded towards the middle of the water inlet and adjusted to the second state, the trash rack forms a filtering structure covering the water inlet.
