[0002] Farmland drainage structures usually refer to naturally formed waterways exposed on the surface or dug for drainage purposes, and generally do not include concealed drainage pipes buried below the surface of farmland. In addition, farmland water conservancy projects not only need to divert water for irrigation, but also need to do a good job of drainage design to discharge excess surface rainfall runoff and control groundwater levels.

[0003] In the related art, a Chinese patent with publication number CN212865821U proposes a drainage structure for a farmland water conservancy project, which includes a drainage ditch, and multiple step sections are arranged on opposite sides of the drainage ditch, and the multiple step sections are evenly spaced along the length direction of the drainage ditch; the step sections are arranged in a stepped shape, and the upper side of the step sections is flush with the upper side of the drainage ditch; multiple groups of interception bars are arranged on opposite sides of the drainage ditch, and the multiple interception bars in the same group are in the same vertical plane, and the interception bars are arranged close to the step sections. This application has the effect of making it convenient for farmers to get water from the drainage ditch.

[0004] The above-mentioned related technologies have the following defects: farmland water conservancy projects need to input irrigation water to each farmland during the dry season or the planting season, and at the same time need to drain excess rainwater from the farmland even during the drought and flood seasons. Generally, multiple branch waterways leading to the farmland are connected to the main waterway, and irrigation and drainage must be flexibly adjusted according to the needs of different farmlands. Therefore, there is an urgent need for a drainage structure that can meet the diverse needs of farmland. Utility Model Content

[0005] In order to meet the diverse irrigation and drainage needs of farmland, the present application provides a drainage structure for a farmland water conservancy project.

[0006] The drainage structure of a farmland water conservancy project provided in this application adopts the following technical solution:

[0008] Sealing components are provided on the side walls of the branch water channel and the main water channel close to the connecting portion. When the sealing plate is turned over to block the connecting portion, the sealing plate is tightly pressed against the sealing component.

[0009] Furthermore, the acute angle between the branch waterway and the main waterway is located on the side of the branch waterway facing the water flow direction of the main waterway.

[0010] Furthermore, the locking structure includes a locking rod hinged on the upper end surface of one side of the sealing plate, the branch waterway is provided with a sliding seat sliding along its length direction and a locking assembly for driving the sliding seat to slide and lock, and the locking rod is hinged to the sliding seat at one end away from the sealing plate.

[0011] Furthermore, the locking assembly includes a mounting seat fixedly connected to the branch waterway, on which screws arranged along its length direction are rotatably installed at intervals, and the sliding seat is slidably arranged on the mounting seat and threadedly sleeved on the screw.

[0012] Furthermore, the sealing assembly includes a sealing strip arranged along the length direction of the side edge of the sealing plate, and when the sealing plate is turned over to seal the connecting portion, the sealing plate abuts against the sealing strip.

[0013] Furthermore, the sealing assembly further comprises a rubber strip fixedly connected to the seal, and the rubber strip is located on a side of the flipping direction of the seal when facing the sealing plate to seal the connecting portion.

[0014] Furthermore, the rubber strip has a cavity therein.

[0015] Furthermore, a flexible filter net is connected between the side edge of the sealing plate and the two side walls of the branch water channel.

[0016] In summary, the beneficial technical effects of this application are:

[0017] When some farmlands need to take water for irrigation or drain water, the sealing plate can be driven to flip to open the connecting part. At this time, a part of the sealing plate is flipped to extend into the main waterway. When the branch waterway is in the state of taking water for irrigation, the sealing plate can intercept the water flow in the main waterway to a certain extent to increase the water intake of the branch waterway; when the branch waterway is in the state of draining water, the sealing plate can also block the impact of the water flow in the main waterway to a certain extent, so that the water flow in the branch waterway can be smoothly discharged into the main waterway. When it is necessary to block the branch waterway from the main waterway, just flip the sealing plate until it is tight against the sealing component. At this time, the sealing plate can effectively isolate the connecting part, which can meet the diverse drainage needs of different farmlands along the main waterway.

[0021] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0022] The present application embodiment discloses a drainage structure of a farmland water conservancy project. Figure 1 A drainage structure of a farmland water conservancy project includes a main waterway 1 and a plurality of branch waterways 2 connected to the sides of the main waterway 1. The plurality of branch waterways 2 are arranged in sequence along the water flow direction of the main waterway 1 and are respectively arranged corresponding to a plurality of farmlands. The main waterway 1 and the branch waterways 2 can be cast as one piece or assembled from prefabricated water troughs. A connecting portion 3 is provided between the branch waterway 2 and the main waterway 1. A fixed shaft 41 is vertically fixedly connected to the middle of the bottom wall of the connecting portion 3. A sealing plate 42 for blocking / opening the connecting portion 3 is rotatably sleeved on the fixed shaft 41. A locking structure for locking the sealing plate 42 at any flipping position is provided on the branch waterway 2.

[0023] Sealing components are provided on the side walls of the branch water channel 2 and the main water channel 1 close to the connecting portion 3. When the sealing plate 42 is turned over to block the connecting portion 3, the sealing plate 42 is tightly pressed against the sealing component.

[0024] After such arrangement, when some farmlands need to take water for irrigation or drain water, the sealing plate 42 can be driven to flip to open the connecting portion 3. At this time, a part of the sealing plate 42 is flipped to extend into the main waterway 1. When the branch waterway 2 is in the state of taking water for irrigation, the sealing plate 42 can intercept the water flow in the main waterway 1 to a certain extent to increase the water intake of the branch waterway 2; when the branch waterway 2 is in the state of draining water, the sealing plate 42 can also block the impact of the water flow in the main waterway 1 to a certain extent, so that the water flow in the branch waterway 2 can be smoothly discharged into the main waterway 1. When it is necessary to block the branch waterway 2 from the main waterway 1, it is only necessary to flip the sealing plate 42 until it is tightly pressed against the sealing component. At this time, the sealing plate 42 can effectively block the connecting portion 3, which can meet the diversified drainage needs of different farmlands along the main waterway 1.

[0025] Specifically, considering that the water flow in the main waterway 1 is generally greater than the water flow in the branch waterway 2, in order to ensure the smoothness of the branch waterway 2 during drainage and flood relief, Figure 1The branch water channel 2 and the main water channel 1 are arranged to be connected obliquely, specifically, the acute angle between the branch water channel 2 and the main water channel 1 is located on the side of the branch water channel 2 facing the water flow direction of the main water channel 1.

[0026] In this way, when the water in the branch waterway 2 is discharged, it can flow out along the water flow in the main waterway 1, and the resistance it encounters from the water flow in the main waterway 1 is relatively small, so the water can be drained conveniently and smoothly.

[0027] And, refer to Figure 1 and Figure 2 The above-mentioned locking structure includes a locking rod 51 hinged on the upper end face of one side edge of the sealing plate 42, a sliding seat 52 sliding along its length direction and a locking assembly for driving the sliding seat 52 to slide and lock are provided on the branch waterway 2, and the end of the locking rod 51 away from the sealing plate 42 is hinged to the sliding seat 52; the locking assembly includes a mounting seat 53 fixedly connected to the branch waterway 2, and a screw rod 54 arranged along its length direction is installed on the mounting seat 53 at intervals and rotated, the sliding seat 52 is slidably arranged on the mounting seat 53 and threadedly sleeved on the screw rod 54. When specifically set, a turning handle is fixed to the end of the screw rod 54, and a waterproof cover for covering the screw rod 54 and the sliding seat 52 is provided on the branch waterway 2 to ensure the service life of the screw rod 54 and the sliding seat 52 as much as possible.

[0028] After such arrangement, when the sealing plate 42 needs to be adjusted, the screw 54 can be rotated, and the screw 54 can drive the slide 52 to slide on the mounting seat 53 when rotating. When the slide 52 slides, the locking rod 51 can pull or push the sealing plate 42 to flip over. Therefore, by rotating the locking rod 51 forward or backward, the sealing plate 42 can achieve the effect of blocking or opening the connecting portion 3; at the same time, because the screw 54 has a reverse self-locking function when driving the slide 52 to move to any position, the position of the sealing plate 42 can be effectively locked. And with the help of the pushing effect of the locking rod 51 on the sealing plate 42, the sealing plate 42 can be pressed more tightly and firmly against the sealing assembly to ensure the blocking effect of the sealing plate 42.

[0029] In order to ensure the sealing effect after the sealing plate 42 blocks the connecting portion 3, refer to Figure 1 and Figure 2 The sealing component includes a sealing strip 61 arranged along the length direction of the side edge of the sealing plate 42. The two sealing strips 61 are cast with concrete on the two side walls of the branch waterway 2 respectively. When the sealing plate 42 is flipped over to block the connecting portion 3, the sealing plate 42 and the sealing strip 61 abut against each other. The sealing component also includes a rubber strip 62 fixed to the sealing strip 61. The rubber strip 62 is arranged along the length direction of the sealing strip 61. The rubber strip 62 is located on one side of the flipping direction when the sealing strip 61 faces the sealing plate 42 to block the connecting portion. The rubber strip 62 has a cavity therein to achieve an elastic sealing effect so as to fit the branch waterway 2 and the sealing plate 42 made of concrete.

[0030] After such arrangement, when the sealing plate 42 is turned over to seal the connecting portion 3 , the two side edges of the sealing plate 42 respectively approach the two sealing strips 61 and press the two rubber strips 62 , thereby separating the main water channel 1 and the branch water channel 2 well.

[0031] In addition, refer to Figure 1 A flexible filter net 7 is connected between the side of the sealing plate 42 and the two side walls of the branch waterway 2. The flexible filter net 7 can be a nylon net, a yarn net, a cotton woven net, etc. By setting the flexible filter net 7, some debris can be filtered to prevent the debris in the main waterway 1 and the branch waterway 2 from interfering with each other.

[0032] The implementation principle of the drainage structure of a farmland water conservancy project in the embodiment of the present application is:

[0033] When some farmlands need to be watered for irrigation or drained for flooding, the sealing plate 42 can be driven to flip over to open the connecting portion 3. At this time, a part of the sealing plate 42 is flipped over to extend into the main waterway 1. When the branch waterway 2 is in the watering and irrigation state, the sealing plate 42 can intercept the water flow in the main waterway 1 to a certain extent to increase the water intake of the branch waterway 2; when the branch waterway 2 is in the drainage and flooding state, the sealing plate 42 can also block the impact of the water flow in the main waterway 1 to a certain extent, so that the water flow in the branch waterway 2 can be smoothly discharged into the main waterway 1. When it is necessary to block the branch waterway 2 from the main waterway 1, it is only necessary to flip the sealing plate 42 until it is tightly pressed against the sealing component. At this time, the sealing plate 42 can effectively block the connecting portion 3, which can meet the diversified drainage needs of different farmlands along the main waterway 1.
