Description

Technical Field

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

[0002] Irrigation is the technical measure of watering the land with water to supplement the water needed by crops. In order to ensure the normal growth of crops, it is necessary to supply them with sufficient water. Under natural conditions, the water requirements of crops are often not met due to insufficient rainfall or uneven distribution. Therefore, it is necessary to carry out artificial irrigation to make up for the lack of natural rainfall.

[0003] Current irrigation methods mostly involve pumping water from rivers or canals and then transporting it to farmland through pipelines. This process presents several problems: 1. To prevent debris from entering the pump, a filter screen is installed outside. However, after a period of use, this screen is easily clogged by debris in the water flow, affecting water extraction efficiency and potentially overloading the equipment and burning out the pump motor. 2. After irrigation, the heavy pump sinks to the bottom, making it difficult to remove. A rope is needed to pull the pump out, which is not only laborious but also carries the risk of collision with underwater obstacles, damaging the equipment. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an irrigation device for water conservancy projects, and the technical solution adopted is as follows:

[0005] An irrigation device for water conservancy projects includes an external filter box, a water pump inside the external filter box, an internal filter screen outside the water pump, a front top plate installed at one end of the external filter box, a rear cover plate installed at the other end of the external filter box, a float plate installed at one corner inside the external filter box, and airbags installed on both sides below the float plate inside the external filter box. The airbags are connected to an external air source through air pipes.

[0006] Furthermore, the water pump is connected to a water pipe, and both the water pipe and the air pipe are led out through a reserved hole in the rear cover plate. A sealing device for fixing the air pipe and the water pipe is provided in the hole.

[0007] Furthermore, a handle is provided on the top of the external filter box, which facilitates the daily handling of the device.

[0008] Furthermore, the buoyancy of the float plate is less than the sum of the weights of the external filter box and the water pump. Under the action of the float plate, the side of the external filter box without mesh is kept close to the bottom of the water, preventing the silt at the bottom of the water from being sucked in by the water pump.

[0009] Furthermore, filter mesh holes are provided on the surface of the front top plate and on both sides of the external filter box. This can effectively intercept and flush away debris on the surface of the external filter box while maintaining a stable water flow into the external filter box, thus preventing the mesh holes from becoming clogged and ensuring the stable operation of the water pump.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] This utility model achieves multi-directional filtration of water flow through the setting of the front top plate and the triangular prism structure of the external filter box. While ensuring that water flows into the external filter box, it can effectively wash away the debris on the surface of the external filter box, reduce the risk of clogging of the external filter box, and ensure water intake efficiency. At the same time, an internal filter screen is also set inside the external filter box, which further improves the filtration effect and ensures the normal operation of the water pump.

[0012] This invention features a float plate at one corner of the external filter box. Under the action of the float plate, this corner of the external filter box will float, thereby ensuring that the device is always in the correct state. The correct state means that the side of the external filter box without mesh is in close contact with the bottom of the water, so that the water flow can fully enter the external filter box through the two sides with mesh, ensuring the filtration effect is maximized.

[0013] This invention enables the device to float and sink flexibly by using an airbag, making it easy to float to the surface after irrigation, facilitating the recovery of the device, and avoiding damage caused by collisions with underwater obstacles during recovery. Attached Figure Description

[0020] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0021] As attached Figure 1-4 As shown.

[0022] An irrigation device for water conservancy projects includes an outer filter box 1 with a triangular prism structure. The outer filter box 1 has a space for installing a water pump 41 inside. An inner filter screen 4 is also provided outside the water pump 41. Through the dual filtration of the inner filter screen 4 and the outer filter box 1, impurities can be effectively intercepted, ensuring the normal operation of the water pump 41.

[0023] A front top plate 2 protruding outward is installed at one end of the external filter box 1, as shown in the attached figure. Figure 1 As shown, when the device is placed in a canal or river, the front top plate 2 faces the direction of the water flow, which can play a role in diverting and buffering, reducing the impact of the water flow on the device. At the same time, it can also guide floating objects to both sides of the outer filter box 1, ensuring that the mesh openings in the front top plate 2 are not blocked by floating objects.

[0024] Furthermore, a float plate 5 is provided in one corner inside the outer filter box 1. The buoyancy of the float plate 5 is less than the sum of the weights of the outer filter box 1 and the water pump 41, so that the device can be placed on the bottom of the water while ensuring that the device is submerged. Figure 1 The state shown is such that the side of the external filter box 1 without mesh is in close contact with the bottom of the water to prevent the silt at the bottom of the water from being sucked in by the water pump 41.

[0025] Mesh openings are provided on the other two sides of the outer filter box 1, which cooperate with the mesh openings of the front top plate 2 to form a multi-directional filtration channel. Under the diversion effect of the front top plate 2, when the water flows from both sides of the outer filter box 1, part of the water flows into the outer filter box 1 under the suction of the water pump, while the other part of the water can continue to flow along both sides of the outer filter box 1, which can effectively wash away the debris on the surface of the outer filter box 1, thereby preventing the accumulation of debris and clogging of the outer filter box 1.

[0026] A rear cover plate 3 is provided at the other end of the outer filter box 1. Inside the outer filter box 1 and on both sides below the float plate 5, airbags 6 are installed. The airbags 6 are connected to an external air source through an air pipe 61. The inflation volume of the airbags 6 can be adjusted as needed to change the buoyancy of the device. After irrigation is completed, the device can float to the water surface, which is convenient for the device to be retrieved and avoids collision between the device and underwater obstacles.

[0027] The water pump 41 is connected to the water pipe 42. The air pipe 61 and the water pipe 42 are both led out through the reserved hole of the rear cover plate 3. A sealing device is provided at the hole to make close contact with the air pipe 61 and the water pipe 42, so as to ensure that the air pipe 61 and the water pipe 42 inside the outer filter box 1 will not be pulled, and to ensure the tightness of the connection between the pipeline and the device.

[0028] The sealing device can use a rubber gasket smaller than the outer diameter of the air pipe 61 and the water pipe 42, which is fixed by tightening the nut and pressed tightly against the outer wall of the air pipe 61 and the water pipe 42; or it can use a braided strip wrapped around the air pipe 61 and the water pipe 42 at the position of the outer filter box 1 to form a plug larger than the reserved hole in the rear cover plate 3, thereby avoiding the risk of the air pipe 61 and the water pipe 42 being pulled.

[0029] Furthermore, the fixing of the air pipe 61 and the water pipe 42 allows the device to be pulled to the shore by pulling the air pipe 61 or the water pipe 42 after it floats up. Then, the device can be lifted out of the container by the handle 11 provided above the outer filter box 1.

[0030] The procedure for using this device is as follows: Place the device in a canal or river. To ensure sufficient pumping capacity, the device should be placed at a suitable water depth. During placement, inflate the air bladder 6 to make the device float on the surface. After pushing the device to the predetermined position using a long pole, gradually deflate it to allow it to sink to the bottom. During the sinking process, keep the front top plate facing the direction of the water flow. The float plate will keep the device afloat. Figure 1 As shown, the water is placed at the bottom of the water, and the water pump 41 starts to work. The water flows through the multi-directional filter screen into the outer filter box 1. After being filtered again by the inner filter screen 4, the water is pumped by the water pump 41 to the water pipe 42 and delivered to the irrigation system.

[0031] After irrigation is completed, the airbag 6 is inflated by an external air source, causing the device to float to the water surface. The device can then be pulled to the shore via the air pipe 61 or the water pipe 42 for recovery.

[0032] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
