Description

Technical Field

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

[0002] In rainy regions of my country, especially in southern provinces, frequent heavy rainfall often leads to poor drainage in farmland. When water depth exceeds the tolerance range of crops and persists for an extended period, it can cause severe agricultural disasters. The main harms are: excessively deep water gradually depletes oxygen in the soil, causing oxygen deficiency in crop roots, which can lead to reduced yields or even crop failure in severe cases; however, excessive drainage reduces the water and fertilizer use efficiency of farmland and easily causes water quality deterioration in downstream water bodies. Therefore, scientifically regulating farmland water levels is crucial. However, current common drainage facilities lack precision in regulation, making it difficult to accurately maintain the ideal water level required for crop growth, which directly affects the normal growth and final yield of crops. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1-6 The illustrated farmland drainage control device, applicable to different drainage system layouts, includes:

[0027] The inlet guide plate 100 is used to intercept the water flow and direct the water flow into the inlet pipe 200;

[0028] The water inlet pipe 200 is installed on the water inlet guide plate 100 at one end and on the main body of the control box 300 at the other end, and is used to guide the water flow intercepted by the water inlet guide plate 100 into the control box 300.

[0029] The control box 300 is used to regulate the water level in farmland. It has a built-in flow stabilizer 301 and an adjustment plate assembly 302. The flow stabilizer 301 is located near the water inlet pipe 200. The adjustment plate assembly 302 includes an installation groove 302a set on the inner wall of the control box 300. Multiple heightening plates 302b that can be inserted and combined are set in the installation groove 302a. The flow stabilizer 301 has several holes.

[0030] The outlet pipe 400 is connected at one end to the control box 300 to discharge water that exceeds the water level.

[0031] Specifically, the inlet guide plate 100 has an inlet hole, one end of the inlet pipe 200 is connected to the inlet guide plate 100 through a flange, and the other end of the inlet pipe 200 is also connected to the control box 300 through a flange. The mounting groove 302a is set on the inner walls of both sides of the control box 300, and the flow stabilizing plate 301 is fixedly installed on the inner walls of both sides of the control box 300. The flow stabilizing plate 301 and the regulating plate assembly 302 divide the control box 300 into three areas: the flow stabilizing area, the regulating area, and the drainage area. The area near the inlet pipe 200 is the flow stabilizing area. The water flows into the control box 300 through the inlet pipe 200 and is stabilized by the flow stabilizing plate 301 in the flow stabilizing area. It then enters the regulating area through the holes on the flow stabilizing plate 301. The water level is controlled by the height of the raising plate 302b in the regulating area. The height of the raising plate 302b is the water level.

[0032] Furthermore, the top of the extension plate 302b is provided with a groove, and the bottom of the extension plate 302b is provided with a protrusion. The groove and the protrusion cooperate to complete the insertion of the two extension plates 302b.

[0033] It should be noted that the mating relationship between the groove and the protrusion not only forms the assembly relationship but also plays a certain role in sealing.

[0034] Furthermore, a sensor sleeve 303 is provided on the side of the box located between the flow stabilizer 301 and the regulating plate assembly 302. A sensor is installed inside the sensor sleeve 303. A triangular notch is provided on the top of the regulating plate 302b to cooperate with the sensor.

[0035] Specifically, the sensor is a water level sensor, and there are two sensor sleeves 303, one in the steady flow zone and the other in the drainage zone.

[0036] It should be noted that the triangular notch forms a triangular weir at the top of the regulating plate assembly 302. The water level sensor, in conjunction with the triangular weir, can estimate the flow rate of farmland drainage based on the triangular weir flow formula. The water level sensor is located in the sensor sleeve 303, which serves to protect the device and improve the detection accuracy. The design of two sensor sleeves 303 further enhances the measurement accuracy.

[0037] Furthermore, an overflow hole 304 is provided on the plate surface of the tank body that connects to the water outlet pipe 400.

[0038] It should be noted that the overflow hole 304 prevents the input flow rate from exceeding the maximum water storage capacity of the control device.

[0039] Furthermore, the top of the water inlet guide plate 100 is provided with an overflow notch 101.

[0040] It should be noted that the overflow gap 101 prevents the input flow from being too large and exceeding the maximum water storage capacity of the control device.

[0041] Furthermore, it also includes a heightening plate replacement tool 500 for replacing the heightening plate 302b. The side of the heightening plate 302b is provided with bolts 302c that cooperate with the heightening plate replacement tool 500. The heightening plate replacement tool 500 is provided with a pair of locking holes 501 that cooperate with the bolts 302c.

[0042] Specifically, the heightening plate replacement tool 500 is a plate-shaped structure with an overall T-shape. The locking hole 501 is located in the horizontal part of the T-shape, and the vertical part is used for manual gripping.

[0043] It should be noted that underwater operation of the extension plate 302b is not convenient due to water pressure. The extension plate replacement tool 500 can be used to easily install or remove the extension plate 302b. Specifically, align the locking hole 501 of the extension plate replacement tool 500 with the bolt 302c on the extension plate 302b, insert it, and then lift the extension plate replacement tool 500 upwards to remove the extension plate 302b. The same principle applies to installation.

[0044] The principle of this utility model will be explained below.

[0045] Step 1, Equipment Installation:

[0046] Fix the inlet guide plate 100 at a suitable location in the trench to ensure that all the water in the trench flows through the inlet pipe 200 into the control box 300 after it is collected. After fixing the inlet guide plate 100, connect the inlet pipe 200. Both ends of the inlet pipe 200 have flange assemblies to prevent water leakage. Connect the other end to the control box 300. It is recommended to dig 5-10cm down according to the size of the control box 300 and line the ground with concrete so that the control box 300 fits perfectly in the trench, thereby increasing the stability of the control box 300 and making it perpendicular to the bottom of the trench. After fixing, connect the outlet pipe 400. One end of the outlet pipe 400 has a flange structure.

[0047] The second step is to start draining the channel and begin operating the device:

[0048] As the farmland is drained, the water flow is intercepted by the inlet guide plate 100 and then flows into the control box 300 through the inlet pipe 200. The number of raised plates 302b on the mounting slot 302a can be adjusted as needed to regulate the farmland water level. Taking rice and wheat rotation as an example, irrigation systems can be formulated according to the needs of different regions, different crops, and different growth stages. The number of raised plates 302b can be set according to the requirements, and drainage can be controlled by changing and adjusting the raised plates 302b. A triangular weir with an included angle of 45° is opened in the middle of the uppermost raised plate 302b. During the rice paddy flooding period, a higher farmland water level is required, so the number of raised plates 302b is increased to raise the farmland water level. During the drying period, the number of raised plates 302b is reduced to lower the farmland water level. In particular, the raised plates 302b and the triangular weir plates of this device are assembled with slots, coupled vertically, which greatly improves the anti-leakage effect of the device. This utility model also features a specially designed replacement structure for the heightening plate 302b and the triangular weir plate. Using the heightening plate replacement tool 500 can greatly improve the convenience of replacement. The tool has a locking hole 501, which includes a large hole and a small groove. The large hole facilitates locking the tool with the bolt 302c of the weir plate, and the small groove locks with the bolt 302c, which facilitates subsequent disassembly and installation.

[0049] The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
