DETAILED DESCRIPTION

[0023] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0024] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0025] like Figure 1-Figure 5 As shown, the present invention provides a device applied to a pump gate to realize a two-way pumping function through a one-way pump, comprising: a mounting seat 1, a two-way pipe 2, a one-way pump 3 and four one-way valves 4; the mounting seat 1 is arranged on the inner wall of a water pipe 5, the two-way pipe 2 is arranged on the mounting seat 1, the one-way pump 3 is arranged inside the two-way pipe 2, and the one-way valve 4 is arranged at the end of the two-way pipe 2.

[0026] The working principle of the above technical solution: In order to realize the two-way pumping function of the gate, it is first necessary to install the mounting seat 1 on the inner wall of the water pipe 5, and perform sealing treatment to prevent water leakage at the connection between the mounting seat 1 and the water pipe 5, and then the one-way pump 3 can be used to pump water. When the one-way pump 3 is pumping water, the four one-way valves 4 will be opened and closed respectively, so that the water flow in the water pipe 5 can be controlled by different one-way valves 4 on the two-way pipe 2 to realize the operation of pumping water from left to right or from right to left.

[0027] The beneficial effects of the above technical solution: through the design of the above structure, the two-way tube 2 is installed on the mounting base 1 and the connection with the mounting base 1 is sealed to prevent water leakage. The water flow in the water pipe 5 can be pumped by the one-way pump 3. At the same time, four one-way valves 4 are respectively arranged on the four water outlets of the two-way tube 2, and the one-way valves 4 with the same direction are respectively located on both sides of the mounting base 1. In this way, the passage of water flow can be guaranteed and the backflow of water on one side can be prevented. After that, only one one-way pump 3 is needed to realize the change of the pumping direction in the water pipe 5 through the switch coordination between the one-way valves 4.

[0028] In one embodiment, a pedestal 11 is provided on the side wall of the mounting seat 1, and the pedestal 11 is clamped with the inner wall of the water pipe 5. The mounting seat 1 is connected to the water pipe 5 through the pedestal 11. The mounting seat 1 is provided with a first through hole, a second through hole and a third through hole, and the bidirectional tube 2 is connected to the mounting seat 1 through the first through hole, the second through hole and the third through hole.

[0029] The working principle of the above technical solution is as follows: a pedestal 11 for connecting to the water pipe 5 is provided on the side wall of the mounting seat 1, and the pedestal 11 is clamped in the inner wall of the water pipe 5, which can effectively prevent the mounting seat 1 from being washed away by excessive water pressure. At the same time, a first through hole, a second through hole and a third through hole for installing a two-way tube 2 are also provided on the mounting seat 1, and the two-way tube 2 passes through and is installed in the first through hole, the second through hole and the third through hole.

[0030] The beneficial effects of the above technical solution: through the design of the above structure, the two-way tube 2 is installed in the first through hole, the second through hole and the third through hole and sealed, which can effectively separate the water flow on the left and right sides of the mounting seat 1. At the same time, the mounting seat 1 is clamped in the inner wall of the water pipe 5 through the base 11, which can prevent the mounting seat 1 from being washed away due to excessive water pressure in the water pipe 5, and can also use the pressure of the water pressure in the water pipe 5 to make the clamping relationship between the base 11 and the water pipe 5 tighter and more firm.

[0031] In one embodiment, the bidirectional tube 2 includes a central first through tube 21, a second through tube 22, a third through tube 23, a first transfer tube 221 and a second transfer tube 231. The first through tube 21 passes through the first through hole, the second through tube 22 passes through the second through hole, and the third through tube 23 passes through the third through hole. The first transfer tube 221 and the second transfer tube 231 are both arranged on the side wall of the first through tube 21. The first through tube 21 is communicated with the second through tube 22 through the first transfer tube 221, and the first through tube 21 is communicated with the third through tube 23 through the second transfer tube 231. The first transfer tube 221 is located on the left side of the mounting seat 1, and the second transfer tube 231 is located on the right side of the mounting seat 1. The four one-way valves 4 are respectively arranged at the left and right ends of the first through tube 21, the right end of the second through tube 22 and the left end of the third through tube 23. The one-way pump 3 is arranged in the first through tube 21, and the one-way pump 3 is located between the first transfer tube 221 and the second transfer tube 231.

[0032] The working principle of the above technical solution is as follows: when the gate starts to operate, the one-way pump 3 is used to pump water. When the one-way pump 3 pumps water from left to right, in order to allow the water in the water pipe 5 to flow from left to right, the water in the water pipe 5 will enter from the one-way valve 4 at the left end of the first through-pipe 21, and then flow to the right end of the first through-pipe 21 through the one-way pump 3, and flow out from the one-way valve 4 at the right end of the first through-pipe 21. At this time, when the water flows through the first transfer pipe 221 to reach the second through-pipe 22, the direction of the water flow is still from left to right. At this time, the one-way valve 4 at the right end of the second through-pipe 22 is not opened, so no water will flow out from the right end of the second through-pipe 22, and the water in the third through-pipe 23 flows from right to left. At this time, the one-way valve 4 at the left end of the third through-pipe 23 is also not opened. It is not opened, so the water flow in the third through pipe 23 will not flow back from the left end of the third through pipe 23 to the water pipe 5 at the left end of the mounting seat 1; without changing the pumping direction of the one-way pump 3, if the water flow in the water pipe 5 needs to flow from right to left, at this time, the one-way valve 4 at the right end of the second through pipe 22 and the one-way valve 4 at the left end of the third through pipe 23 are opened, and the water flow will flow from the second through pipe 22 through the first transfer pipe 221 to the one-way pump 3, and through the one-way pump 3 to the second transfer pipe 231, and finally to the third through pipe 23 and be discharged from the one-way valve 4 at the left end of the third through pipe 23. At this time, because the one-way valves 4 at both ends of the first through pipe 21 are in the closed state, it is possible to prevent water from flowing back from the right end of the first through pipe 21 to the water pipe 5. The principle is the same when the one-way pump 3 pumps water from right to left.

[0033] The beneficial effects of the above technical solution: through the design of the above structure, when the one-way pump 3 pumps water from left to right, if the water flows from left to right, the water flow in the water pipe 5 will not flow back from the third through pipe 23 to the water pipe 5 on the left side of the mounting seat 1. At the same time, when the one-way pump 3 pumps water and controls the water flow from right to left, the water flow in the water pipe 5 will not flow back from the first through pipe 21 to the water pipe 5 on the right side of the mounting seat 1, and the user can adjust the pumping direction of the one-way pump 3 and the installation direction of the one-way valve 4 as needed, thereby adjusting the selection of the water flow path in the water pipe 5.

[0034] In one embodiment, the four one-way valves 4 are respectively a first one-way valve 100, a second one-way valve 200, a third one-way valve 300 and a fourth one-way valve 400; the first one-way valve 100 is arranged at the left end of the first through pipe 21, the second one-way valve 200 is arranged at the right end of the second through pipe 22, the third one-way valve 300 is arranged at the left end of the third through pipe 23, and the fourth one-way valve 400 is arranged at the right end of the first through pipe 21.

[0035] The working principle of the above technical solution: in order to facilitate the distinction and control of the switching of the one-way valve 4, the four one-way valves 4 are respectively named as the first one-way valve 100, the second one-way valve 200, the third one-way valve 300 and the fourth one-way valve 400, and the four one-way valves 4 are respectively set on the four ports of the two-way pipe 2.

[0036] The beneficial effects of the above technical solution: through the design of the above structure, the four one-way valves 4 are respectively installed on the four ports of the two-way pipe 2, and the first one-way valve 100, the second one-way valve 200, the third one-way valve 300 and the fourth one-way valve 400 are used to distinguish the one-way valve 4 of each port, so as to facilitate the regulation and determination of the path entrance and exit of the water flow.

[0037] In one embodiment, the first one-way valve 100 is in the same direction as the fourth one-way valve 400 , the second one-way valve 200 is in the same direction as the third one-way valve 300 , and the first one-way valve 100 is in opposite directions to the second one-way valve 200 .

[0038] The working principle of the above technical solution: in this embodiment, the water outlet directions of the first one-way valve 100 and the fourth one-way valve 400 are consistent, the water outlet directions of the second one-way valve 200 and the third one-way valve 300 are consistent, and the water outlet directions of the first one-way valve 100 and the second one-way valve 200 are opposite. In actual applications, the flow direction of each one-way valve 4 and the position of the installation port can be determined according to the user's own needs and in combination with the pumping direction of the one-way pump 3.

[0039] The beneficial effects of the above technical solution: through the design of the above structure, the selection of water flow in the water pipe 5 can select different paths according to the different setting directions of each one-way valve 4, and each one-way valve 4 can be set according to the commonly used water flow direction and the first through pipe 21 is used as the main flow channel, and the four one-way valves 4 are electrically connected to each other, so that the opening and closing of the four one-way valves 4 can be switched at the same time as the water flow direction is switched, thereby realizing the synchronous switching of the water flow direction and the water flow channel, and the electrical connection method can ensure that the switching between the one-way valves 4 is carried out synchronously, thereby preventing the backflow of water due to the untimely opening and closing of the one-way valves 4.

[0040] In one embodiment, the one-way valve 4 includes a connecting pipe 41, a plurality of gate knives 42 and a backflow cover 43; the left end of the connecting pipe 41 is respectively connected to the left and right ends of the first through pipe 21, the right end of the second through pipe 22 and the left end of the third through pipe 23, the gate knife 42 is arranged in the connecting pipe 41, and the backflow cover 43 is arranged on the right end surface of the connecting pipe 41.

[0041] The working principle of the above technical solution: In this embodiment, the connection method of the one-way valve 4 is that the backflow cover 43 on the first one-way valve 100 and the fourth one-way valve 400 are both arranged on the right side, while the backflow cover 43 of the second one-way valve 200 and the third one-way valve 300 are both arranged on the left side. The gate knife 42 realizes the opening and closing of the one-way valve 4 in the connecting pipe 41. When the gate knife 42 is opened, the water flow path is opened, and when the gate knife 42 is closed, the water flow path is closed. The backflow cover 43 arranged at the end of the connecting pipe 41 can fit tightly with the surface of the connecting pipe 41 through the pressure of water pressure when the water flow impacts in the reverse direction, thereby reducing the impact of the water flow on the gate knife 42 to increase the service life of the one-way valve 4 and provide waterproof protection when the gate knife 42 is worn and leaks.

[0042] The beneficial effects of the above technical solution: through the design of the above structure, it is possible to avoid the situation where the gate knife 42 is not completely closed and leaks when the one-way valve 4 is opened and closed. At the same time, the backflow cover 43 can prevent the water pressure of the water flow from impacting the gate knife 42 when the water flows backwards, causing the gate knife 42 to leak or be damaged.

[0043] In one embodiment, a connecting shaft is provided at the right end of the connecting pipe 41 , and the counterflow cover 43 is connected to the right end of the connecting pipe 41 via the connecting shaft. The diameter of the counterflow cover 43 is greater than the diameter of the connecting pipe 41 .

[0044] The working principle of the above technical solution is: the diameter of the backflow cover 43 needs to be larger than the diameter of the connecting pipe 41 to ensure that the backflow cover 43 can completely cover the end face of the connecting pipe 41 under the pressure of the backflow water flow, thereby playing a role of sealing and leak-proofing, and can ensure that the backflow cover 43 only exists on one side of the connecting pipe 41, and will not be washed into the connecting pipe 41 by the water flow to touch the gate knife 42, thereby avoiding affecting the normal opening and closing of the gate knife 42, and the connecting pipe 41 and the backflow cover 43 are connected by a connecting shaft, so that when the water flows downstream, the backflow cover 43 will be pushed up by the water flow and rotate along the connecting shaft.

[0045] Beneficial effect of the above technical solution: through the design of the above structure, the backflow cover 43 can be only present at one end of the connecting pipe 41 and can achieve a perfect sealing effect during the backflow of water.

[0046] In one embodiment, a linkage mechanism is disposed on the inner wall of the connecting tube 41 , and the gate 42 is connected to the inner wall of the connecting tube 41 via the linkage mechanism.

[0047] The working principle and beneficial effects of the above technical solution: the knife switch 42 can realize the opening and closing in the connecting pipe 41 through the linkage mechanism.

[0048] In one embodiment, a mounting groove is provided on the inner wall of the water pipe 5, a sealing ring is provided in the mounting groove, the pedestal 11 is provided in the mounting groove, and the pedestal 11 is connected to the mounting groove by screws.

[0049] The working principle of the above technical solution is as follows: an installation groove is provided on the inner wall of the water pipe 5 for installation and fixation with the pedestal 11, a sealing ring is first set in the installation groove and then the pedestal 11 is inserted into the installation groove, and the pedestal 11 and the installation groove are fixed by screws and the sealing ring between the pedestal 11 and the installation groove is pressed to achieve a sealing effect.

[0050] The beneficial effects of the above technical solution: through the design of the above structure, after the pedestal 11 is installed in the mounting groove, it can better cope with the impact of downstream and upstream water flow, because when the mounting base 1 is impacted by water flow, in addition to the screws that can fix the pedestal 11, the strong water flow impact will make the pedestal 11 tightly attached to the inner wall of the mounting groove, and the sealing ring in the mounting groove can also greatly increase the firmness and sealing between the mounting base 1 and the inner wall of the water pipe 5.
