Description

Technical Field

[0001] This utility model relates to the field of irrigation canal technology, specifically a water conservancy irrigation canal. Background Technology

[0002] Irrigation canals are waterways that connect irrigation water sources with irrigated land. They transport and distribute water drawn from the water source to various parts of the irrigation area. Within an irrigation area, irrigation canals are divided into five levels according to the size of the controlled area: main canals, branch canals, distribution canals, farm canals, and field canals. Irrigation areas with complex terrain and large areas may also have additional levels of canals, such as main canals, branch canals, tributaries, and distribution branches.

[0003] Chinese patent CN219118098U discloses an irrigation canal that includes a gate transmission device and a gate assembly. When the two work together, a motor is started, driving a fixed column to rotate. This, in turn, drives two main gears to rotate. The main gears mesh with two rectangular blocks, allowing the gate body to move vertically within a limiting groove via two T-shaped blocks. Therefore, personnel can quickly open and close the gate by starting the motor, controlling the water flow in the irrigation canal and facilitating its use.

[0004] In the above scheme, the gate moves up and down inside the channel to intercept the water flow. However, irrigation canals typically use a combination of main canals and branch canals, diverting water from the main canal to the branch canals for irrigation, which is inconvenient and inefficient. Therefore, we propose a water conservancy irrigation canal to solve these problems. Utility Model Content

[0005] 1) Technical problems to be solved

[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a water conservancy irrigation canal.

[0007] (ii) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: an irrigation canal, comprising:

[0009] The foundation is embedded in the ground.

[0010] The main channel is fixedly connected to the foundation. The main channel has an inlet and an outlet. A barrier box is slidably connected inside the inlet and outlet. A baffle is fixedly connected to one end of the barrier box. A water inlet net is embedded in the barrier box. A drain outlet is provided on the barrier box.

[0011] A movable component, installed on the main channel, is used to complete drainage by inserting a barrier box into the main channel.

[0012] The secondary channel is fixedly connected to the foundation and is located below the barrier box. A drainage ditch is provided on the secondary channel.

[0013] Furthermore, it also includes a filter screen, which is detachably installed inside the main channel, with the bottom end of the filter screen forming a 30-degree angle with the bottom surface of the main channel.

[0014] Furthermore, an installation strip is fixedly connected to the filter screen, and a positioning screw is fixedly connected to the main channel. The installation strip has a through hole, and the installation strip is inserted into the positioning screw through the through hole. A locking nut is threaded onto the positioning screw, and the bottom end of the locking nut is in contact with the installation strip.

[0015] Furthermore, a support column is fixedly connected to the filter screen, and the bottom end of the support column abuts against the inner bottom wall of the main channel.

[0016] Furthermore, a second sealing groove and a first sealing groove are respectively provided on both sides of the inner wall of the main channel, and a first sealing ring and a second sealing ring are respectively fixedly connected to both sides of the baffle. The first sealing ring is adapted to the second sealing groove, and the second sealing ring is adapted to the first sealing groove.

[0017] Furthermore, the movable component includes a bracket fixedly connected to the main channel, an adjusting screw rotatably connected to the bracket, a movable block threadedly connected to the adjusting screw, and the bottom end of the movable block fixedly connected to the baffle.

[0018] (iii) Beneficial effects:

[0019] Compared with existing technologies, this irrigation canal has the following advantages:

[0020] I. This utility model achieves effective control of water flow in the main channel through the design of a unique barrier box and moving components. When irrigation is needed, the operator can manually or electrically rotate the adjusting screw to move the moving block, which in turn moves the baffle and barrier box laterally, thereby changing the position of the barrier box and achieving the purpose of intercepting or releasing water flow in the main channel. This not only simplifies the operation process and improves the flexibility of irrigation, but also allows for quick adjustment of the irrigation area according to actual needs, thus improving irrigation efficiency.

[0021] Second, by designing the secondary channel to correspond with the inlet and outlet of the main channel, this utility model can accurately collect water discharged from the drain outlet of the barrier box and distribute it evenly to the farmland through the drainage trough on the secondary channel, thus realizing the rational allocation of water resources. Furthermore, by precisely controlling the opening and closing of each inlet and outlet, the irrigation volume can be flexibly adjusted according to the water requirements of different crops, which helps to save water and improve the water resource utilization rate. It is of great significance for promoting water-saving irrigation technology. Attached Figure Description

[0026] 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.

[0027] like Figure 1-3 As shown, this utility model provides a technical solution: a water conservancy irrigation canal, including a foundation 1, a main channel 2, a moving component, a secondary channel 16, and a filter screen 11.

[0028] Foundation 1 is embedded in the ground and is a reinforced concrete composite structure.

[0029] The main channel 2 is fixedly connected to the foundation 1. The main channel 2 has an inlet and outlet 3. The number of inlets and outlets 3 can be adjusted according to actual needs. A barrier box 4 is slidably connected inside the inlet and outlet 3. A baffle 5 is fixedly connected to one end of the barrier box 4. The baffle 5 covers the connection between the inlet and outlet 3 and the barrier box 4 to seal it. A water inlet net 6 is embedded in the barrier box 4. A drain outlet 7 is opened on the barrier box 4. Water in the main channel 2 can enter the interior of the barrier box 4 through the water inlet net 6 and be discharged from the barrier box 4 through the drain outlet 7.

[0030] The inner wall of the main channel 2 is provided with a second sealing groove 21 and a first sealing groove 10 on both sides. The two sides of the baffle 5 are fixedly connected with a first sealing ring 8 and a second sealing ring 9. The first sealing ring 8 is adapted to the second sealing groove 21, and the second sealing ring 9 is adapted to the first sealing groove 10.

[0031] The barrier box 4 exists in two states on the main channel 2. In one state, the first sealing ring 8 on the baffle 5 is inserted into the second sealing groove 21, and the barrier box 4 is located outside the main channel 2. In this state, the water will flow continuously inside the main channel 2. In the other state, the second sealing ring 9 on the baffle 5 is inserted into the first sealing groove 10, and the barrier box 4 is located inside the main channel 2, thus completing the interception of the water in the main channel 2. The water in the main channel 2 will enter the barrier box 4 through the water inlet net 6.

[0032] The filter screen 11 is detachably installed inside the main channel 2. The bottom end of the filter screen 11 forms a 30-degree angle with the bottom surface of the main channel 2. Since the filter screen 11 is installed at an angle inside the main channel 2, it can filter the impurities in the water inside the main channel 2 and reduce the situation of impurities clogging the inlet and outlet 3.

[0033] An installation strip 12 is fixedly connected to the filter screen 11, and a positioning screw 13 is fixedly connected to the main channel 2. The installation strip 12 has a through hole and is inserted into the positioning screw 13 through the through hole. A locking nut 14 is threadedly connected to the positioning screw 13, and the bottom end of the locking nut 14 is in contact with the installation strip 12.

[0034] The filter screen 11 is detachable and can be installed by means of the mounting strip 12, the positioning screw 13 and the locking nut 14, which makes it convenient to replace and clean the filter screen 11.

[0035] A support column 15 is fixedly connected to the filter screen 11, and the bottom end of the support column 15 abuts against the inner bottom wall of the main channel 2. The support column 15 is used to support the filter screen 11, thereby improving the stability of the filter screen 11 during filtration.

[0036] The movable component is installed on the main channel 2 and is used to complete drainage by inserting the barrier box 4 into the main channel 2. The movable component includes a bracket 18 fixedly connected to the main channel 2, an adjusting screw 19 rotatably connected to the bracket 18, a movable block 20 threadedly connected to the adjusting screw 19, and the bottom end of the movable block 20 fixedly connected to the baffle 5.

[0037] The adjustment screw 19 can be rotated manually or driven by a motor. After the adjustment screw 19 is rotated, the moving block 20 will move the barrier box 4 laterally through the baffle 5, completing two working states: the barrier box 4 intercepts and drains water or the barrier box 4 is moved out.

[0038] The secondary channel 16 is fixedly connected to the foundation 1. The secondary channel 16 is located below the barrier box 4. A drainage trough 17 is provided on the secondary channel 16. The number of secondary channels 16 matches the number of inlets and outlets 3. It can collect the water discharged from the drain outlet 7 on the barrier box 4 into the secondary channel 16 and complete the irrigation of the land through the drainage trough 17.
