Description

Technical Field

[0001] The invention relates to the technical field of ditch drainage, in particular to a planting ditch drainage device. Background Art

[0002] In agricultural planting, drainage ditches are usually opened, and water in the river is pumped into the drainage ditches through water pumps to irrigate farmland. Drainage holes are opened between the drainage ditches and the farmland, and drainage gates are set on the drainage holes to close the drainage gates when not in use. However, the existing ditch drainage devices have the following problems:

[0003] (1) When the gate is closed, because the gate moves up and down along the frame, impurities in the ditch inside the frame are easily accumulated. The impurities accumulate at the bottom, causing the gate to be unable to close normally and a gap to appear at the bottom.

[0004] (2) When in use, the water level outside the gate will be detected by the float of the liquid level detection sensor to adjust the gate opening and closing degree. However, during use, the external environment will cause the water surface to fluctuate continuously, causing the float to fluctuate continuously, affecting the normal detection results. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a planting ditch drainage device to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a planting ditch drainage device, comprising a frame installed above the ditch, the inner cavity of the frame is slidably connected with a gate driven by a driving mechanism, a liquid level detection component is arranged on the left side of the frame, the inner cavity of the ditch is provided with a concave section, the bottom of the frame extends to the inner cavity of the concave section, the bottom of the frame is connected with a reflux bucket, the reflux bucket is placed in the inner cavity of the concave section and fits with its surface, a sealing gasket is fixedly connected to the right side of the frame, an elastic airbag cushion abutting the inner cavity of the concave section is fixed to the right side of the sealing gasket, a receiving plate is fixedly connected to the bottom of the inner cavity of the frame, the surface of the receiving plate is covered with a waterproof pad separating the receiving plate from the inner cavity of the frame, and the bottom of the receiving plate is fixedly connected to an extrusion pad fixedly connected to the bottom of the inner cavity of the frame The surface of the extrusion airbag is connected with the elastic airbag cushion through a connecting pipe. When drainage is required during use, the electric hoist drives the gate to rise and then discharge the water. When drainage is not required, the electric hoist lowers the gate, and the gate descends along the frame, and then the rear abuts against the left side of the sealing pad, and then continues to press down. At this time, the gate enters the inner concave section, and the bottom is squeezed above the waterproof pad, and the extrusion airbag is squeezed downward through the receiving plate. Then the gas in the extrusion airbag enters the elastic airbag cushion through the connecting pipe, and the elastic airbag cushion squeezes the sealing pad toward the gate to seal the gap between the gate and the right ditch, which can effectively block water. Moreover, through the setting of the inner concave section, the gate does not have to be lowered to the lowest side. Even if there are impurities and other obstructions below, it will not affect the normal closing and sealing of the gate.

[0007] As a further solution of the present invention: the driving mechanism is an electric hoist, which drives the wire rope to connect with the top of the gate, driving the gate to move up and down, without using a screw to rotate and lift the gate, which can effectively avoid the problem of the screw rusting and deforming due to long-term use affecting the lifting efficiency.

[0008] As a further solution of the present invention: the inner concave section is a right-angled trapezoid with a right-angled side on the right side and a larger upper portion and a smaller lower portion; the reflow hopper is a triangle and fits with the left side of the inner concave section.

[0009] As a further solution of the present invention: the liquid level detection assembly includes a sensor body fixed on the left side of the frame and a cover body covering the upper part of the sensor body, and a cavity for liquid level to enter is arranged at the bottom of the cover body.

[0010] As a further solution of the present invention: a filter screen is fixedly connected to the bottom of the inner cavity of the cover body, and impurities such as water plants can be prevented by setting the filter screen.

[0011] As a further solution of the present invention: the inner cavity of the cover body is fixedly connected to a plurality of guide rods, the surfaces of the plurality of guide rods are slidably connected to two buffer plates, the surfaces of the two buffer plates are respectively provided with guide grooves slidably connected to the surfaces of the guide rods, and the inner cavities of the two buffer plates are provided with evenly distributed hole grooves. The arrangement of the buffer plates on the guide rods effectively reduces the impact force of water surface fluctuations. When the water surface is fluctuated by external forces, the buffer plates are pushed to move on the guide rods. The two buffer plates effectively buffer the fluctuations of the water surface and reduce the fluctuations of the water surface, so that the water surface can rise more smoothly, thereby preventing the float on the sensor body from constantly fluctuating due to water surface fluctuations, thereby affecting the normal monitoring effect.

[0012] As a further solution of the present invention: the holes and grooves on the surfaces of the two buffer plates are staggered, which can effectively reduce the impact force while ensuring the water level rises.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In the present invention, when drainage is not needed, the electric hoist lowers the gate, the gate descends along the frame, and then the rear abuts against the left side of the sealing pad, and then continues to press down. At this time, the gate enters the inner concave section, and the lower part is squeezed above the waterproof pad, and the airbag is squeezed downward through the receiving plate. Then the gas in the airbag enters the elastic airbag cushion through the connecting pipe, and the elastic airbag cushion squeezes the sealing pad toward the gate, and seals the gap between the gate and the right ditch, which can effectively block water. Moreover, through the setting of the inner concave section, the gate does not need to be lowered to the lowest side. Even if there are impurities and other obstacles below, it will not affect the normal closing and sealing of the gate.

[0015] 2. In the present invention, when the water surface is subjected to external forces and generates fluctuations, the buffer plate is pushed to move on the guide rod, and the two buffer plates are used to effectively buffer and reduce the fluctuations of the water surface, so that the water surface can rise more smoothly, and the floating ball on the sensor body is prevented from constantly fluctuating due to the fluctuations of the water surface, thereby affecting the normal monitoring effect.

When drainage is needed during use, the electric hoist 3 drives the gate 2 to rise and then discharge the water. When drainage is not needed, the electric hoist 3 lowers the gate 2, and the gate 2 descends along the frame 1, and then the rear abuts against the left side of the sealing pad 10, and then continues to press down. At this time, the gate 2 enters the inner concave section 19, and the bottom is squeezed above the waterproof pad 5, and the airbag 7 is squeezed downward through the receiving plate 6. Then the gas in the airbag 7 enters the inner part of the elastic airbag cushion 9 through the connecting pipe 8.

Moreover, through the setting of the inner concave section 19, the gate 2 does not have to be lowered to the lowest side. Even if there are impurities and other obstacles below, it will not affect the normal closing and sealing of the gate 2.

[0024] The driving mechanism is an electric hoist 3, which drives the wire rope to connect with the top of the gate 2, and drives the gate 2 to move up and down.
