Description

Technical Field

[0001] The utility model belongs to the technical field of water supply systems, in particular to a water pump suction system that is easy to maintain. Background Art

[0002] One of the important links in fish pond farming is to change the water in the fish pond. In the current fish pond farming, most of them will use a professional water pump suction system to pump out the old water in the pond to improve the degree of automation; the existing water pump suction system is mainly composed of a water pump and a through pipe. The water pump can pump water and discharge the old water in the pond through the through pipe. The operation is simple and convenient.

[0003] However, in actual use, it is found that the existing water pump suction system still has at least the following defects:

[0004] First, there may be gas inside the pipe before pumping, which will increase the pressure on the pump when pumping water, increase the burden on the pump and shorten its service life;

[0005] Secondly, when the water pump is damaged or the pipe is blocked and cannot pump water normally, it needs to be inspected and maintained. However, since there may be water accumulation inside the pipe at this time, the weight of the pipe is large, which makes it inconvenient for workers to pull and disassemble the pipe normally, and the operation convenience is poor.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See attached Figure 1 -Attached Figure 2 A water pump suction system that is easy to maintain includes a water pump (not shown) and a suction pipe 1, the suction pipe 1 includes a through pipe 11, a guide head 12, a switch valve 13, a one-way valve 14 and a conduit 15; a first three-way valve 111 and a second three-way valve 112 are respectively installed at both ends of the through pipe 11, the first three-way valve 111 connects the switch valve 13 and the guide head 12, and the switch valve 13 connects the water pump; the second three-way valve 112 connects the one-way valve 14 and the conduit 15, and the one-way valve 14 connects the pond; the guide head 12 and the conduit 15 can be opened or closed.

[0025] Specifically, before pumping water, the conduit 15 is extended out of the pond surface, and the switch valve 13, the guide head 12 and the conduit 15 are opened. The guide head 12 is connected with a water pipe, and water is injected into the through pipe 11 through the guide head 12, so that the gas inside the through pipe 11 is discharged to the outside through the conduit 15. After all the gas is discharged and water flows out of the conduit 15, the guide head 12 and the conduit 15 are closed. Since the through pipe 11 is filled with water at this time, the water pump can run normally quickly, reducing the initial operation and debugging time of the water pump. Since there is no empty suction phenomenon, the burden of the water pump can be reduced and the service life of the water pump can be extended.

[0026] Before inspection and maintenance, the conduit 15 is extended into the pond, the switch valve 13 is closed, and the guide head 12 and the conduit 15 are opened. Since the one-way valve 14 restricts the backflow of water inside the through pipe 11, the water inside the through pipe 11 can only flow into the pond through the conduit 15 under the action of air pressure at this time, so as to reduce the weight of the through pipe 11, facilitate workers to pull and disassemble the through pipe 11 for inspection, and improve the convenience of operation.

[0027] In summary, the utility model is used in conjunction with a water pump by arranging a through pipe 11, a guide head 12, a switch valve 13, a one-way valve 14 and a conduit 15, so as to discharge the gas inside the through pipe 11 before pumping water, thereby reducing the burden on the water pump, and to discharge the water inside the through pipe 11 before maintenance, thereby reducing the weight of the through pipe 11 and improving the convenience of operation.

[0028] See attached Figure 1 -Attached Figure 2 A ball valve f1 or an electronic valve f2 is installed on both the guide head 12 and the conduit 15. The installation of the ball valve f1 or the electronic valve f2 makes it convenient for the user to open or close the guide head 12 and the conduit 15. As for whether to use the ball valve f1 or the electronic valve f2, or to install the ball valve f1 or the electronic valve f2 at the same time, the utility model does not impose any restrictions on this.

[0029] See attached Figure 1 -Attached Figure 2 The suction pipe 1 also includes a mesh pipe 16 , the one-way valve 14 is connected to the mesh pipe 16 , and is connected to the pond through the mesh pipe 16 , and a filter 160 is installed at the pipe mouth of the mesh pipe 16 .

[0030] Specifically, when in use, the mesh tube 16 is placed in the pond, and the water in the pond can be sucked into the through pipe 11 through the mesh tube 16 and the one-way discharge by starting the water pump; wherein, the filter part 160 can adopt a filter block or a filter net, and the filter block or the filter net is provided with filter holes for filtering out large particles of impurities. Since the filter block or the filter net are both existing products, they are not elaborated in detail in the utility model.

[0031] See attached Figure 1 -Attached Figure 2 The mesh mouth tube 16 is trumpet-shaped, and the diameter of the pipe mouth of the mesh mouth tube 16 gradually increases. This design can effectively expand the water absorption range of the mesh mouth tube 16 and improve the convenience of pumping water.

[0032] See attached Figure 1 -Attached Figure 2 The through pipe 11 and the conduit 15 are both made of transparent materials. This design makes it easy for users to check the internal conditions of the through pipe 11 and the conduit 15, making blockage faults visible and ensuring that users can accurately control the start and stop timing of the water pump.

[0033] See attached Figure 1 -Attached Figure 2 There are various types of transparent materials. For ease of understanding, in this embodiment, the through pipe 11 and the catheter 15 are both steel wire hoses; the steel wire hose is an existing product, which has good flexibility and transparency and is extremely convenient to use.

[0034] See attached Figure 1 -Attached Figure 2 A water flow detector 3 is also installed on the first three-way valve 111; when there is a blockage or abnormal suction phenomenon in the system, the water flow detector 3 will be disconnected accordingly and an alarm will be issued to remind the user that the pipeline is abnormal.

[0035] See attached Figure 1 -Attached Figure 2 The utility model also includes an extension pipe 2, and a plurality of suction pipes 1 are provided. The water pump is synchronously connected to the switch valves 13 of the plurality of suction pipes 1 through the extension pipe 2.

[0036] Among them, the water pump can perform synchronous suction through the extension pipe 2 and multiple groups of suction pipe fittings 1; in addition, during use, if one group of suction pipe fittings 1 is damaged, the switch valve 13 of the group of suction pipe fittings 1 is closed, and the guide head 12 and the conduit 15 of the group of suction pipe fittings 1 are opened to discharge the water in the through pipe 11 of the group of suction pipe fittings 1, so as to facilitate maintenance; at the same time, the remaining groups of suction pipe fittings 1 can continue to operate normally, realizing non-stop maintenance.

[0037] It should also be noted that, although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present application.
