Description

Technical Field

[0001] The utility model belongs to the field of non-point source pollution prevention and control, and particularly relates to a non-point source pollution interception device for ditches. Background Technique

[0002] Farmland non-point source pollution refers to the organic or inorganic substances such as soil particles, nitrogen, phosphorus, pesticides, heavy metals, rural livestock manure and domestic garbage in farmland. From non-specific areas, under the action of precipitation and runoff scouring, through farmland surface runoff, farmland drainage and underground seepage, a large amount of pollutants enter the receiving water bodies (rivers, lakes, reservoirs, bays), causing pollution. Farmland drainage is the end link of agricultural non-point source pollution, which will bring the residual chemical fertilizers and pesticides after agricultural production into the river course. Among them, nutrients such as nitrogen and phosphorus and other organic or inorganic pollutants will directly affect the water quality of the river course. Therefore, it is necessary to increase ecological ditches, intercepting dams, etc., which can effectively intercept substances such as nitrogen and phosphorus in farmland drainage and surface runoff, reduce the input of fertilizers and pesticides into the river course from the source, achieve the purpose of controlling nutrient loss, reducing water pollutants, improving the farmland ecological environment, and building an excellent ecological cycle. The non-point source pollution interception device for ditches is a facility used to reduce and control water non-point source pollution, and is mainly applied to urban drainage systems, agricultural irrigation areas and other areas where non-point source pollution may occur.

[0003] For example, the Chinese utility model with the application number 2023225307047 discloses a farmland non-point source pollution interception device. After placing the installation shell inside the farmland water channel and pressing down the top plate, during the downward movement of the top plate, the installation rod and the soil-breaking cone are driven to move downward, so that the soil-breaking cone is inserted into the inner side of the water channel, and the top plate is fixed to the water channel, thereby fixing the installation plate and the interception device, reducing the installation difficulty of the interception device and improving the installation efficiency of the interception device.

[0004] However, in the above-mentioned disclosed technical solution, when cleaning the pollutants, the pollutants are pushed into the aggregate box arranged at the bottom of the device. However, when the aggregate box is full, it is not convenient to clean the aggregate box.

[0005] In summary, at present, a non-point source pollution interception device for ditches that can facilitate the cleaning of the aggregate box is needed. Content of the Utility Model

[0006] The purpose of the utility model is to provide a non-point source pollution interception device for ditches. The device can dump the pollutants in the aggregate box by lifting the aggregate box, solving the problem of difficult cleaning of the aggregate box.

[0007] The technical solution adopted by the utility model to solve the above problems is: a non-point source pollution interception device for ditches, including:

[0008] An installation box, and a servo motor is fixedly connected to the top of the installation box;

[0009] Cleaning mechanism, the cleaning mechanism includes gears, two sets of gears are provided, the two gears mesh with each other, the gears are rotatably connected to the inner wall of the installation box, the rotating shaft of one of the gears is connected to the output end of the servo motor, the bottom of the gear is fixedly connected with a lead screw, a connecting plate is threadedly connected to the lead screw, both ends of the connecting plate are fixedly connected with collection troughs, a push plate is slidably connected in the collection troughs, one end of a connecting rod is rotatably connected to the top of the push plate, and the other end of the connecting rod is rotatably connected to the installation box;

[0010] Base, the top of the base is fixedly connected with a filter screen, both sides of the filter screen are fixedly connected with fixing plates, and a collecting box is penetrated through the fixing plates.

[0011] Among them, the servo motor is a motor used for precise control of position, speed and acceleration. Compared with ordinary motors, the servo motor has higher control accuracy and response speed.

[0012] The lead screw is a common mechanical component, usually used for transmitting motion and force, and is widely used in various mechanical equipment. The main function of the lead screw is to convert rotational motion into linear motion.

[0013] The filter screen is a mechanical device for separating solid particles from liquid or gas. Its main function is to filter out unwanted impurities or pollutants through a physical barrier to ensure the cleanliness and quality of the fluid.

[0014] A further preferred technical solution is that the bottom of the lead screw is rotatably connected to the base.

[0015] A further preferred technical solution is that a sliding groove for the push plate to slide is provided inside the collection trough.

[0016] A further preferred technical solution is that one side of the collection trough abuts against the filter screen.

[0017] A further preferred technical solution is that the filter screen is located between the two lead screws, and one side of the connecting rod abuts against the surface of the filter screen.

[0019] A further preferred technical solution is that soil-breaking cones are fixedly connected to both sides of the bottom of the fixing plate.

[0020] A further preferred technical solution is that both ends of the base abut against the collecting box.

[0021] A further preferred technical solution is that one end of the collecting tank is open.

[0022] The collection trough is V-shaped, and "V-shaped" refers to a shape or structure characterized by two edges converging toward the center to form a "V"-shaped profile. In the design of the collection trough, the V-shaped structure is usually used to guide and concentrate fluids or solid materials so that they flow more efficiently to a specific collection area.

[0023] A further preferred technical solution is that the height of the feed opening of the collecting box is lower than the height of the filter screen.

[0024] In summary, the utility model has the following benefits:

[0025] 1. The utility model uses a collection box, so that after the collection box is full of pollutants, the pollutants in the collection box can be dumped by lifting the collection box, which solves the problem of difficulty in cleaning the collection box and improves the convenience of use of the device.

[0036] A cleaning mechanism for cleaning pollutants. The cleaning mechanism includes two gears 12 for driving a lead screw 5 to rotate. The two gears 12 are meshed with each other, and both gears 12 are rotatably connected to the inner wall of the installation box 1. The rotating shaft of one of the gears 12 is connected to the output end of the servo motor 2. A lead screw 5 for driving a connecting plate 6 to move is fixedly connected to the bottom of the gear 12. The bottom of the lead screw 5 is rotatably connected to a base 8. A connecting plate 6 is threadedly connected to the surface of the lead screw 5. The side of the connecting plate 6 abuts against the side of a filter screen 3. Collection grooves 7 for collecting pollutants are fixedly connected to both ends of the connecting plate 6. A sliding groove for a push plate 13 to slide is formed inside the collection groove 7. The collection groove 7 is V-shaped, and one side of the collection groove 7 abuts against the filter screen 3. One end of the collection groove 7 is open, and the other end is closed. A push plate 13 for pushing pollutants is slidably connected inside the collection groove 7. One end of a connecting rod 4 is rotatably connected to the top of the push plate 13, and the other end of the connecting rod 4 is rotatably connected to the surface of the installation box 1.

[0037] A base 8 of a support device. Both ends of the base 8 abut against the surfaces of two aggregate boxes 9. The top of the base 8 is triangular. A filter screen 3 for filtering pollutants is fixedly connected to the top of the base 8. The filter screen 3 is located between the two lead screws 5. One side of the connecting rod 4 abuts against the surface of the filter screen 3. Fixing plates 10 are fixedly connected to both sides of the filter screen 3. Breaking cones 11 for fixing the device are fixedly connected to both sides of the bottom of the fixing plate 10.
