Description

Technical Field

[0001] The utility model belongs to the technical field of irrigation, in particular to a water conservancy irrigation and drainage device. Background Art

[0002] Irrigation means using water to irrigate the land. The principle of irrigation is that the amount of irrigation, the number of irrigations and the time should be determined according to the water requirements of the medicinal plants, the growth stage, the climate and the soil conditions. It should be timely, appropriate and reasonable. Irrigation is a technical measure to supplement the water needed by crops. In order to ensure the normal growth of crops and obtain high and stable yields, crops must be supplied with sufficient water. Under natural conditions, the water requirements of crops cannot be met due to insufficient precipitation or uneven distribution. Therefore, artificial irrigation must be carried out to make up for the lack of natural rainfall. In the process of water conservancy irrigation, drainage devices will be used.

[0003] However, existing drainage devices still have certain defects: most of the water needed for irrigation usually contains a large amount of impurities, which can easily damage the water pump and clog the relatively small pipes at the back end of the irrigation drainage system when it is extracted through the water pump. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a water conservancy irrigation drainage device, and the technical solutions adopted are as follows:

[0005] A water conservancy irrigation drainage device includes a drainage box, a vertical partition provided inside the drainage box, a filter plate provided on one side of the partition, a connector installed on one side of the drainage box and below the filter plate, the connector being connected to a water inlet pipe; a water outlet pipe installed on the other side of the drainage box and above the filter plate; an inclined platform provided below the partition, and a box cover provided directly above the inclined platform and on the upper surface of the drainage box;

[0006] A groove is provided above the collecting plate, and a spiral rod is installed in the groove in the collecting plate. One end of the spiral rod passes through the inclined platform and out of one side of the drainage box, and a mounting bracket for installing the motor is provided at the position where the spiral rod passes through in the drainage box.

[0007] Furthermore, the motor is connected to the spiral rod in a transmission manner. The spiral rod is driven by the motor to rotate, thereby scraping the sediment accumulated in the groove of the collection plate and discharging it from the opening provided at the bottom of the mounting frame.

[0008] Furthermore, the length of the collecting plate is equal to that of the filter plate above, and the deposited silt accumulates above the collecting plate. The water filtered by the filter plate is discharged through the outlet pipe, and some floating debris can float to the channel under the box cover under the guidance of the inclined platform.

[0009] Furthermore, the other end of the spiral rod passes through one side of a connector provided in the drainage box, and a sealing bearing is provided at the connection point, which can prevent water from escaping while fixing the spiral rod.

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

[0011] The utility model can separate floating objects and sediments in the water flow through the internal structure of the drainage box. The floating objects can float up to the channel below the box cover, and the floating objects below can be salvaged by opening the box cover; the sediments accumulate above the collecting plate and can be cleaned by the rotation of the spiral rod. The water flow after being filtered by the filter screen enters the water outlet pipe, which can avoid damage to the water pump connected to the water outlet pipe and prevent subsequent pipelines from being blocked.

[0012] The connector of the utility model is closely placed under the filter plate. When water in the river channel enters the drainage pipe, the incoming water flow can impact the debris blocked under the filter plate, causing the debris to gather toward one side of the inclined platform. Under the guidance of the inclined platform, floating objects rise upward and are accumulated under the box cover in the drainage box; the sediment slides through the inclined platform and finally accumulates above the collecting plate at the bottom of the drainage box.

[0018] In order to help those skilled in the art better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present invention.

[0019] As attached Figure 1-3 shown.

[0020] A water conservancy irrigation drainage device includes a drainage box 1, a filter plate 11 is provided inside the drainage box 1, a connector 2 is installed on one side of the drainage box 1 and below the filter plate 11, and the connector 2 is connected to the water inlet pipe 3; an outlet pipe 4 is installed on the other side of the drainage box 1 and above the filter plate 11; based on the above structure, the tail end of the water inlet pipe 3 is placed in the river channel, and the outlet pipe 4 is connected to a water pump. After the water pump is started, a negative pressure is formed inside the drainage box 1, and the water flow in the river channel is sucked into the drainage box 1 through the water inlet pipe 3. The water level in the drainage box 1 gradually rises until it rises to the height of the outlet pipe 4. When the water level rises, debris in the water flow can be blocked by the filter plate 11.

[0021] A partition that can separate the drainage box 1 is provided inside the drainage box 1 and on one side of the filter plate 11, and a ramp 7 is provided below the partition. An openable box cover 12 is provided directly above the ramp 7 and on the upper surface of the drainage box 1; with the above structure, when water flows into the drainage box 1 through the connector 2, the water flow can impact the debris blocked under the filter plate 11, causing the debris to gather toward one side of the ramp 7. Under the guidance of the ramp 7, floating debris can float to the channel below the box cover 12, while some silt that is easy to settle will slide through the ramp and eventually accumulate above the collecting plate 5 at the bottom of the drainage box 1.

[0022] The length of the collecting plate 5 is equal to the length of the upper filter plate 11. A triangular groove is provided above the collecting plate 5, and the bottom of the groove is arc-shaped. A screw rod 6 is installed in the groove in the collecting plate 5. One end of the screw rod 6 passes through the side of the connector 2 provided in the drainage box 1, and the other side of the screw rod 6 passes through the inclined platform 7 and passes through the drainage box 1. A mounting bracket 8 for installing a motor 9 is provided at the position where the screw rod 6 passes through the drainage box 1. The motor 9 is connected to the screw rod 6 through a transmission connection, and an opening for mud discharge is provided below the mounting bracket 8.

[0023] Based on the above structure, the motor 9 drives the screw rod 6 to rotate, which can scrape the mud and sand accumulated in the groove of the collecting plate 5 and discharge it from the opening below the mounting frame 8.

[0024] During use, when the spiral rod 6 is not rotating, the outer edge of the spiral rod 6 is in close contact with the inner wall of the opening of the inclined platform 7, which can prevent the water in the drainage box 1 from flowing out.

[0025] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the scope of protection of the utility model.
