Description

Technical Field

[0001] This utility model relates to the field of water conservancy and irrigation technology, and in particular to a farmland water conservancy and irrigation device. Background Technology

[0002] Farmland irrigation refers to a series of measures and facilities that provide irrigation water for farmland, and is crucial for agricultural production.

[0003] Irrigation canals are commonly used for farmland irrigation. However, because these canals are higher than the farmland, water can only be pumped into the fields. This means that during rice cultivation, the water level needs to be monitored closely by farmers, and sluice gates need to be closed to control the flow. Therefore, when planting large quantities of rice, to prevent excessive water levels and flooding during rainy weather, it is necessary to control the flow of water in each paddy field individually, making water management overly cumbersome. To address these shortcomings, we propose a farmland irrigation device. Summary of the Invention

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a farmland irrigation device.

[0005] To address the problems existing in the prior art, this utility model adopts the following technical solution: a farmland irrigation device, comprising:

[0006] The pre-embedded structure includes a pre-embedded cylinder, a water guide pipe fixedly installed at the lower end of the pre-embedded cylinder, a connecting pipe fixedly installed on the surface of the pre-embedded cylinder, and an overflow assembly disposed inside the pre-embedded cylinder.

[0007] The overflow assembly includes a sleeve inserted into the inner wall of the water guide pipe, an overflow pipe slidably connected to the inner wall of the sleeve, and a locking component disposed inside the sleeve for fixing the overflow pipe.

[0008] The locking component includes a tapered groove formed in the inner wall of the sleeve, a tapered spring sleeve fitted on the surface of the overflow pipe, and a nut threaded onto the surface of the sleeve, and the tapered groove allows the tapered spring sleeve to pass through.

[0009] A water supply structure is provided on the left side of the connecting pipe for supplying water to the pre-embedded cylinder.

[0010] A drainage component is provided at the lower end of the water pipe and is used to drain water from the overflow component.

[0011] Preferably, a first rubber sealing ring is fixedly installed on the surface of the sleeve, and the first rubber sealing ring is in close contact with the inner wall of the water guide pipe.

[0012] Preferably, a sedimentation cylinder is fixedly installed on the surface of the sleeve, and the bottom of the sedimentation cylinder is in contact with the inner bottom wall of the pre-embedded cylinder.

[0013] Preferably, a filter cylinder is fixedly installed at the upper end of the overflow pipe, and a filter screen is provided on the surface of the filter cylinder.

[0014] Preferably, the water supply structure includes a water supply pipe, an inlet pipe fixedly installed on the surface of the water supply pipe, and a first connecting flange fixedly installed on the surface of the inlet pipe, and a second connecting flange adapted to the first connecting flange is fixedly installed on the surface of the connecting pipe.

[0015] Preferably, the drainage assembly includes a drain pipe, a diversion pipe fixedly installed on the surface of the drain pipe, and a first connecting flange fixedly installed on the surface of the diversion pipe, and a second connecting flange adapted to the first connecting flange is fixedly installed at the lower end of the water guide pipe.

[0016] Preferably, a second rubber sealing ring is fixedly installed on the surface of the overflow pipe, and the surface of the second rubber sealing ring is in close contact with the inner wall of the sleeve.

[0017] Preferably, the inner wall of the sedimentation cylinder is provided with a handle.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. By setting up a pre-embedded structure and locking components, both the water supply and drainage structures are connected to the pre-embedded cylinder. Then, the pre-embedded structure, water supply structure, and drainage structure are all buried in the farmland, with the upper end of the pre-embedded cylinder at the same plane as the farmland. When the water supply structure fills the pre-embedded cylinder with water, the water will submerge the cylinder. With continued water filling, the water level will rise to be level with the filter cylinder. Excess water can then be discharged into the drainage component along the overflow component. Compared to existing technologies, this device, after burying the pre-embedded structure in the farmland, allows the height of the filter cylinder to be adjusted to the required water level for rice. Water can be filled into the pre-embedded cylinder using the water supply structure, allowing water to enter the farmland for irrigation. As the water level in the farmland rises, excess water can be discharged along the overflow component, thus preventing the water level from becoming too high and submerging the rice, facilitating the operation of the planting personnel.

[0020] 2. By setting up a sedimentation cylinder, when the sleeve is inserted into the water pipe, the bottom of the sedimentation cylinder will contact the inner bottom wall of the pre-embedded cylinder, thereby limiting the water pipe. When the debris in the farmland enters the pre-embedded cylinder and settles, the settled debris will enter the sedimentation cylinder. Then the sedimentation cylinder can be removed from the pre-embedded cylinder, which facilitates the cleaning of the settled debris in the pre-embedded cylinder. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] Please see Figure 1-4 This utility model provides a technical solution: a farmland irrigation device, including: a pre-embedded structure, a water supply structure, and a drainage component.

[0029] The pre-embedded structure includes a pre-embedded cylinder 10, a water guide pipe 11 fixedly installed at the lower end of the pre-embedded cylinder 10, a connecting pipe 12 fixedly installed on the surface of the pre-embedded cylinder 10, and an overflow assembly disposed inside the pre-embedded cylinder 10.

[0030] The water supply structure is located on the left side of the connecting pipe 12 and is used to supply water to the embedded cylinder 10. The water supply structure includes a water supply pipe 60, an inlet pipe 61 fixedly installed on the surface of the water supply pipe 60, and a first connecting flange 62 fixedly installed on the surface of the inlet pipe 61. A second connecting flange 63 adapted to the first connecting flange 62 is fixedly installed on the surface of the connecting pipe 12. One end of the water supply pipe 60 is connected to an external water supply system. After the first connecting flange 62 and the second connecting flange 63 are connected to each other, the inlet pipe 61 and the connecting pipe 12 can be connected as one unit. Water can be diverted into the water supply pipe 60 by the external water supply system. Then the water will enter the embedded cylinder 10 along the inlet pipe 61 and the connecting pipe 12.

[0031] The overflow assembly includes a sleeve 20 inserted into the inner wall of the water guide pipe 11, an overflow pipe 21 slidably connected to the inner wall of the sleeve 20, and a locking component disposed inside the sleeve 20 for fixing the overflow pipe 21. A first rubber sealing ring 22 is fixedly installed on the surface of the sleeve 20, and the first rubber sealing ring 22 fits tightly with the inner wall of the water guide pipe 11. A second rubber sealing ring 80 is fixedly installed on the surface of the overflow pipe 21, and the surface of the second rubber sealing ring 80 fits tightly with the inner wall of the sleeve 20. When the sleeve 20 is inserted into the inner wall of the water guide pipe 11, the first rubber sealing ring 22 will fit tightly with the inner wall of the water guide pipe 11, thereby preventing water in the pre-embedded cylinder 10 from flowing out along the gap between the water guide pipe 11 and the sleeve 20. When the overflow pipe 21 is inserted into the sleeve 20, the second rubber sealing ring 80 will fit tightly with the inner wall of the sleeve 20, thereby preventing water in the pre-embedded cylinder 10 from flowing out along the gap between the sleeve 20 and the overflow pipe 21.

[0032] A sedimentation cylinder 40 is fixedly installed on the surface of the sleeve 20. A handle 90 is provided on the inner wall of the sedimentation cylinder 40, and the bottom of the sedimentation cylinder 40 is in contact with the inner bottom wall of the pre-embedded cylinder 10. When the sleeve 20 is inserted into the water guide pipe 11, the bottom of the sedimentation cylinder 40 will contact the inner bottom wall of the pre-embedded cylinder 10, thereby limiting the water guide pipe 11.

[0033] A filter cylinder 50 is fixedly installed at the upper end of the overflow pipe 21, and a filter screen 51 is provided on the surface of the filter cylinder 50. The locking component includes a conical groove opened in the inner wall of the sleeve 20, a conical spring sleeve 30 sleeved on the surface of the overflow pipe 21, and a nut 31 threadedly connected to the surface of the sleeve 20. The conical groove allows the conical spring sleeve 30 to pass through. Tightening the nut 31 can drive the conical spring sleeve 30 to move downward and contact the conical groove. At this time, the conical spring sleeve 30 will contract and clamp the overflow pipe 21, thereby fixing the overflow pipe 21 and sliding the overflow pipe 21 up and down along the inner wall of the sleeve 20, thereby changing the distance between the inner bottom wall of the pre-embedded cylinder 10 and the filter cylinder 50.

[0034] The drainage assembly includes a drain pipe 70, a drain pipe 71 fixedly installed on the surface of the drain pipe 70, and a first connecting flange 72 fixedly installed on the surface of the drain pipe 71. The lower end of the water guide pipe 11 is fixedly installed with a second connecting flange 73 that is compatible with the first connecting flange 72. After the first connecting flange 72 and the second connecting flange 73 are connected to each other, the drain pipe 71 can be connected to the water guide pipe 11. One end of the drain pipe 70 is connected to an external drainage ditch or pond.

[0035] The water supply structure and drainage structure are connected to multiple pre-buried cylinders 10. Then, the water supply structure and drainage structure are buried in the farmland. One pre-buried structure needs to be buried in each farmland, and the upper end of the pre-buried cylinder 10 is at the same plane as the farmland. When water is injected into the farmland, the water level in the pre-buried cylinder 10 is the same as the water level in the farmland.

[0036] When the water supply structure fills the pre-buried cylinder 10 with water, the water entering the pre-buried cylinder 10 will submerge the pre-buried cylinder 10. After the water continues to be filled, the water level will rise to be level with the filter cylinder 50. The field ridge will store the water in the farmland. Then the excess water can be discharged into the drainage component along the overflow component. As the rice needs different water levels for growth, the height of the filter cylinder 50 can be adjusted. Then the overflow pipe 21 is fixed by the locking component, thereby adjusting the water level in the farmland.

[0037] Compared with existing technologies, this device buries the pre-embedded structure in the farmland, and then the height of the filter cylinder 50 can be adjusted to the water level required by the rice. Water can be injected into the pre-embedded cylinder 10 using the water supply structure, so that water can enter the farmland for irrigation. As the water level in the farmland rises, excess water can be discharged along the overflow component, thereby preventing the rice from being submerged due to excessive water level in the farmland and facilitating the operation of the planting personnel.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art based on the technical solution and concept of the present utility model should be included within the protection scope of the present utility model.
