Description

Technical Field

[0001] This utility model belongs to the field of drainage technology, and more specifically, it relates to an agricultural flood control pumping device. Background Technology

[0002] In agricultural planting areas at risk of flooding, it is necessary to dig irrigation ditches for drainage to guide water flow. However, water in the furrows of the soil cannot be drained. Pumping equipment is needed to pump water, or pre-installed underground pipes can be used to guide excess rainwater out from underground.

[0003] Based on the above, the pumping devices currently in use lack the integrated pumping function of water storage and drainage, making it inconvenient to collect and store excess water for backup, and they do not have the function of simultaneous pumping at multiple points. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an agricultural flood control pumping device, which solves the problems mentioned in the background art that existing pumping devices lack integrated pumping functions for water storage and drainage, are inconvenient to collect and store excess water for backup, and do not have the function of simultaneous pumping at multiple points.

[0005] The purpose and effectiveness of this agricultural flood control pumping device are achieved by the following specific technical means:

[0006] An agricultural flood control pumping device includes a water tank with two sets of base frames fixedly mounted on its bottom with a support. A lower drain pipe is connected to the middle of the bottom of the water tank. A delivery pump and a pumping pipe are connected to the top of the water tank. An external drain pipe is connected to the other end of the delivery pump, and a corrugated pipe A for controlling the drainage position is connected to the bottom of the external drain pipe. A ball valve is connected between the lower drain pipe and the external drain pipe on one side. A corrugated pipe B is connected to the bottom of the pumping pipe, and a four-way connector is connected to the other end of the four-way connector. Corrugated pipes C are connected to the other three interfaces of the four-way connector, and a suction pipe is connected to the bottom of each of the corrugated pipes C. The bottom of the suction pipe is sealed, and an inlet hole is formed around the lower outer side of the suction pipe.

[0007] Furthermore, a connecting ring is fixedly provided at the bottom of the corrugated pipe A; a positioning ring is slidably provided on the outside of the external drain pipe, and two sets of connecting rods are integrally provided at the bottom of the positioning ring, with the positioning ring fixed on both sides of the top of the connecting ring; a set screw is provided on the outside of the positioning ring through a threaded connection.

[0008] Furthermore, a conical mesh cover is fixedly installed on the outside of the water intake pipe, and a pre-embedded water tank is fixedly installed at the bottom of the conical mesh cover.

[0009] Furthermore, the pre-embedded water tank is surrounded by four sets of through grooves, each of which is fixedly equipped with an intercepting cotton plate for water filtration; each intercepting cotton plate is equipped with a supporting frame inside.

[0010] Furthermore, a flange structure is integrally provided on the lower outer side of the water suction pipe, and a sliding ring valve is slidably provided on the outside of the water suction pipe, with an air flotation bladder fixedly provided at the bottom of the sliding ring valve.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The water pumping process of this invention involves a water tank, which provides storage. The pumping unit draws out the contents of the water tank to create negative pressure, causing water to pass sequentially through the suction pipe, corrugated pipe C, four-way valve, corrugated pipe B, and pumping pipe into the water tank. Water accumulates continuously inside the tank, and excess air is extracted. When the water level reaches its maximum and the tank is full, excess water is discharged downwards through the external drain pipe into the drainage ditch, thus achieving automatic drainage and water storage.

[0013] By setting up a pre-buried water tank, multi-point pumping can be achieved. Rainwater in the field accumulates at the pre-buried water tank and enters the tank through the conical mesh cover. Excess water in the soil passes through the intercepting cotton board and enters the pre-buried water tank. As the water level rises, buoyancy, combined with the air flotation bladder, raises the sliding ring valve, exposing the inlet hole. Conversely, when the water in the pre-buried water tank is pumped out, the sliding ring valve descends, sealing the inlet hole and stopping the input of air at this location. This ensures normal pumping at other locations, thus achieving stable multi-point pumping.

[0014] In addition, automatic drainage can be achieved. Loosen the set screw outside the positioning ring, and move the connecting ring downward with the connecting rod. At the same time, stretch the bellows A so that the height of the connecting ring is lower than that of the suction pipe. At this time, turn off the delivery pump and open the ball valve to form a communicating vessel. The suction pipe continues to pump water through air pressure, while the water in the tank moves downward, passes through the bellows A and the connecting ring and is discharged downward, thus achieving automatic drainage.

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0023] Example 1:

[0024] As attached Figure 1 To be continued Figure 5 As shown:

[0025] This utility model provides an agricultural flood control pumping device, including a water tank 1. Two sets of base frames 101 are fixedly installed at the bottom of the water tank 1 with the support. A lower drain pipe 102 is connected to the middle of the bottom of the water tank 1. A delivery pump 2 and a pumping pipe 5 are connected to the top of the water tank 1. An external drain pipe 3 is connected to the other end of the delivery pump 2. A corrugated pipe A301 for controlling the drainage position is connected to the bottom of the external drain pipe 3. A ball valve 4 is connected between the lower side of the external drain pipe 3 and the lower drain pipe 102. A corrugated pipe B6 is connected to the bottom of the pumping pipe 5. A four-way connector 7 is connected to the other end of the corrugated pipe B6. Corrugated pipes C8 are connected to the other three interfaces of the four-way connector 7. A water suction pipe 9 is connected to the bottom of each corrugated pipe C8. The bottom of the water suction pipe 9 is a sealed structure, and a water inlet hole 901 is opened around the lower part of the outside of the water suction pipe 9.

[0026] Among them, a connecting ring 302 is fixedly installed at the bottom of the corrugated pipe A301; a positioning ring 303 is slidably installed on the outside of the external drain pipe 3; two sets of connecting rods 304 are integrally installed at the bottom of the positioning ring 303; the positioning ring 303 is fixed on both sides of the top of the connecting ring 302; a set screw is installed on the outside of the positioning ring 303 by threaded connection.

[0027] Among them, a conical mesh cover 10 is fixedly installed on the outside of the water intake pipe 9, and a pre-embedded water tank 11 is fixedly installed at the bottom of the conical mesh cover 10.

[0028] The pre-embedded water tank 11 has four sets of through grooves around its exterior, and each through groove is fixedly equipped with an intercepting cotton plate 12 for filtering water; each intercepting cotton plate 12 is equipped with a supporting frame inside.

[0029] Among them, the lower part of the water suction pipe 9 is integrally provided with a flange structure, and a sliding ring valve 13 is slidably provided on the outside of the water suction pipe 9. An air flotation bladder 14 is fixedly provided at the bottom of the sliding ring valve 13.

[0030] like Figures 1-5 As shown, when in use, the pre-buried water tank 11 is pre-buried underground, and the cone-shaped mesh cover 10 is exposed above the ground; the external drainage pipe 3 is set above the drainage ditch.

[0031] When it rains, rainwater in the field accumulates at the pre-buried water tank 11, passes through the conical net cover 10 and enters the pre-buried water tank 11. Excess water in the soil passes through the intercepting cotton board 12 and enters the pre-buried water tank 11. The water accumulates in the pre-buried water tank 11. As the water level rises, the sliding ring valve 13 is lifted by buoyancy in conjunction with the air flotation bladder 14, exposing the water inlet hole 901.

[0032] If the water in the pre-embedded water tank 11 is pumped out, the sliding ring valve 13 will descend and close the water inlet 901, so that air is stopped from entering at this position, ensuring that the water suction pipes 9 at other positions can pump water normally.

[0033] The delivery pump 2 is started to draw out the internal material of the water tank 1 to generate negative pressure, so that the water passes through the suction pipe 9, the corrugated pipe C8, the four-way pipe 7, the corrugated pipe B6 and the pumping pipe 5 in sequence into the water tank 1, where it continuously accumulates and excess air is extracted.

[0034] When the water level reaches its maximum and the water tank 1 is full of water, the excess water is discharged downwards through the external drain pipe 3 and discharged into the drainage ditch, thus realizing water pumping.

[0035] Example 2:

[0036] Based on Example 1, when drainage is not urgent, drainage can be slowed down. Loosen the set screw outside the positioning ring 303, and move the connecting ring 302 downward with the connecting rod 304. At the same time, stretch the bellows A301 so that the height of the connecting ring 302 is lower than the suction pipe 9. At this time, turn off the delivery pump 2 and open the ball valve 4 to form a communicating vessel. Through air pressure, the suction pipe 9 continues to pump water, while the water in the water tank 1 will move downward, pass through the bellows A301 and the connecting ring 302 and be discharged downward, thus realizing automatic drainage.

[0037] Ball valve 4 can be replaced and controlled by a solenoid valve.

[0038] Example 3:

[0039] Based on Example 1, the number of four-way connector 7, corrugated pipe C8, suction end pipe 9 and pre-embedded water tank 11 can be increased as needed, thereby increasing the number of pumping positions.

[0040] The specific usage and function of this embodiment are as follows:

[0041] In this utility model, in low-lying areas of farmland, the pre-buried water tank 11 is pre-buried underground, while the cone-shaped mesh cover 10 protrudes above the ground; the external drainage pipe 3 is set above the drainage ditch.

[0042] When it rains, rainwater in the field accumulates at the pre-buried water tank 11, passes through the conical net cover 10 and enters the pre-buried water tank 11. Excess water in the soil passes through the intercepting cotton board 12 and enters the pre-buried water tank 11. The water accumulates in the pre-buried water tank 11. As the water level rises, the sliding ring valve 13 is lifted by buoyancy in conjunction with the air flotation bladder 14, exposing the water inlet hole 901.

[0043] The delivery pump 2 is started to draw out the internal material of the water tank 1 to generate negative pressure, so that the water enters the water tank 1 in sequence through the suction pipe 9, the corrugated pipe C8, the four-way pipe 7, the corrugated pipe B6 and the pumping pipe 5. The water continuously accumulates in the water tank 1, and the excess air is drawn out. When the water level reaches the maximum and the water tank 1 is full of water, the excess water is discharged downward through the external drain pipe 3 and discharged into the drainage ditch.

[0044] If the water in the pre-embedded water tank 11 is pumped out, the sliding ring valve 13 will descend and close the water inlet 901, so that air is stopped from entering at this position, ensuring that the water suction pipes 9 at other positions can pump water normally.

[0045] As needed, loosen the set screw outside the positioning ring 303, and move the connecting ring 302 downward with the connecting rod 304. At the same time, stretch the bellows A301 so that the height of the connecting ring 302 is lower than the suction end pipe 9. At this time, turn off the delivery pump 2 and open the ball valve 4 to form a communicating vessel.

[0046] Using air pressure, the suction pipe 9 continues to draw water, while the water in the water tank 1 moves downward, passing through the corrugated pipe A301 and the connecting ring 302 to be discharged downward, thus achieving automatic drainage.
