Description

Technical Field

[0001] This utility model relates to the field of soil and water conservation and control, and in particular to a protective device for soil and water conservation and control. Background Technology

[0002] Globally, approximately 25 billion tons of productive soil, or about 5 to 7 million hectares of arable land, are destroyed by soil erosion each year. The soil itself is loose, and rainwater continuously washes away this loose soil, generating large amounts of muddy water mixture that flows away, which is a major reason for the severe soil erosion situation. Therefore, one existing method for controlling soil erosion in loose soil is to use a plastic film to cover the soil to prevent rainwater from directly washing away the soil and causing soil erosion.

[0003] Existing soil and water conservation devices use membranes to intercept rainwater before it reaches the ground, preventing it from directly eroding the soil. However, they do not treat the rainwater that accumulates on the membranes. The continuous accumulation of rainwater can easily cause the membranes to break, damaging the devices. Newly falling rainwater will then wash away the soil, creating a muddy-water mixture that flows away, resulting in poor soil and water conservation effects. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a protective device for soil and water conservation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A protective device for soil and water conservation includes a mounting frame, a telescopic motor, and a rainwater collector. The rainwater collector is installed on both sides of the mounting frame. Support legs are rotatably mounted on the mounting frame. A membrane and a connecting rod are fixedly mounted on the mounting frame. The output end of the telescopic motor is fixedly connected to a push rod via a connecting rod. The push rod abuts against the connecting rod. An installation block is fixedly mounted on the push rod. A switch and a spring are fixedly mounted on the installation block. The switch corresponds to the telescopic motor. A pressing plate is fixedly mounted on the spring. A cleaning component is installed on the membrane.

[0007] Preferably, the cleaning assembly includes a cleaning housing slidably connected to the film. Slide grooves are formed on both sides of the mounting frame. A slider matching the corresponding slide groove is fixedly installed on one side wall of the cleaning housing. A rotating shaft is rotatably installed between the inner walls of the cleaning housing. The rotating shaft passes through the other side wall of the cleaning housing and extends into the corresponding slide groove. A rack is fixedly installed in the corresponding slide groove. A gear meshing with the rack is fixedly sleeved on the rotating shaft. A cleaning roller is fixedly installed on the rotating shaft.

[0008] Preferably, the film is fixedly connected to the inner wall of the rainwater collector, and the film is an elastic silicone film.

[0009] Preferably, a stabilizing frame is fixedly connected to the mounting bracket, and the stabilizing frame is a mesh structure.

[0010] Preferably, a scraper is fixedly installed inside the cleaning housing, and the scraper has a chamfer.

[0011] Preferably, the shaft, support, mounting bracket, rack, and gear are all coated with a waterproof coating.

[0012] Compared with the prior art, the beneficial effects of this utility model are: rainwater accumulation on the film causes the film to deform, triggering the telescopic motor switch. The telescopic motor pushes out to change the film into a shape that is high in the middle and low on both sides, allowing rainwater to flow out to both sides and preventing rainwater from breaking the film. Then the telescopic motor resets, and the film continues to intercept rainwater in a shape that is low in the middle and high on both sides. In addition, a cleaning component is installed, which assists the rainwater to flow out to both sides by scraping water with a scraper. After the scraper scrapes water, a cleaning roller cleans the surface of the film to reduce rainwater residue on the film surface. Attached Figure Description

[0019] Reference Figures 1-5A protective device for soil and water conservation includes a mounting frame 2, a telescopic motor 6, and a rainwater collector 16. The telescopic motor 6 is a servo motor. In its initial retracted state, the mounting frame 2 is tilted downwards towards the center. Therefore, when the telescopic motor 6 returns to its initial state, the cleaning casing 18 moves to the center due to gravity. The rainwater collector 16 is installed on both sides of the mounting frame 2 and contains planted plants. Rainwater from the film 3 flows into the rainwater collector 16 and is absorbed by the plants. Support legs 1 are rotatably mounted on the mounting frame 2. The film 3 and connecting rod 4 are fixedly mounted on the mounting frame 2. A push rod 5 is fixedly connected to the output end of the telescopic motor 6 via a connecting rod. The push rod 5 abuts against the connecting rod 4. When the telescopic motor 6 pushes the push rod 5 upwards via the connecting rod, the upward movement of the push rod 5... The connecting rod 4 rotates, causing the mounting frame 2 to rotate. When the telescopic motor 6 drives the push rod 5 to move downward through the connecting rod, the push rod 5 no longer supports the connecting rod 4. Under the action of gravity, the connecting rod 4 and the mounting frame 2 rotate downward around the support leg 1. When the telescopic motor 6 drives the push rod 5 to move downward through the connecting rod, the connecting rod 4 and the mounting frame 2 return to their initial positions. A mounting block 7 is fixedly installed on the push rod 5. A switch 10 and a spring 8 are fixedly installed on the mounting block 7. The switch 10 corresponds to the telescopic motor 6. When the switch 10 is triggered, the telescopic motor 6 works once to complete one retraction. A squeezing plate 9 is fixedly installed on the spring 8. When rainwater accumulates on the membrane 3, the membrane 3 will deform and squeeze the squeezing plate 9. The squeezing plate 9 will move when squeezed, triggering the switch 10. A cleaning component is installed on the membrane 3.

[0020] The cleaning assembly includes a cleaning housing 18 slidably connected to the film 3. The mounting frame 2 has grooves 17 on both sides. A slider matching the corresponding groove 17 is fixedly installed on one side wall of the cleaning housing 18. A rotating shaft 13 is rotatably installed between the inner walls of the cleaning housing 18. The rotating shaft 13 passes through the other side wall of the cleaning housing 18 and extends into the corresponding groove 17. A rack 12 is fixedly installed in the corresponding groove 17. A gear 11 meshing with the rack 12 is fixedly sleeved on the rotating shaft 13. A cleaning roller 14 is fixedly installed on the rotating shaft 13. The cleaning roller 14 cleans the residual rainwater on the film 3, making the film 3 clean.

[0021] The membrane 3 is fixedly connected to the inner wall of the rainwater collector 16, and the membrane 3 is an elastic silicone membrane, which ensures that the membrane 3 will deform rather than break when the telescopic motor 6 is working.

[0022] A stabilizing frame is fixedly connected to the mounting bracket 2. The stabilizing frame supports the film 3, making the film 3 less prone to damage. The stabilizing frame has a mesh structure with mesh openings corresponding to the extrusion plate 9.

[0023] A scraper 15 is fixedly installed inside the cleaning housing 18, and the scraper 15 has a chamfer. When the mounting frame 2 rotates, the scraper 15 scrapes away the rainwater on the film 3.

[0024] The rotating shaft 13, support leg 1, mounting bracket 2, rack 12 and gear 11 are all coated with a waterproof coating, which makes them less susceptible to rust from rainwater and extends the service life of the device.

[0025] In this invention, during rainfall, rainwater falls onto the surface of the film 3 and flows towards the center of the film 3 under the influence of gravity. The film 3 is made of elastic silicone, and the rainwater will compress and deform the film 3. As rainwater accumulates on the surface of the film 3, the deformation of the film 3 increases, compressing the compression plate 9. The compression plate 9 is moved by the compression, triggering the switch 10. The switch 10 controls the telescopic motor 6 to extend and retract once. When the telescopic motor 6 pushes the push rod 5 upward through the connecting rod, the movement of the push rod 5 causes the connecting rod 4 and the mounting bracket 2 to move. The connecting rod 4 and the mounting bracket 2 rotate upward around the support leg 1 as the axis, and the film 3 deforms into a shape that is high in the middle and low on both sides. The rainwater slides to both sides. At the same time, the cleaning sleeve 18 moves to both sides under the influence of gravity, causing the scraper 15 to move as well. The movement of the scraper 15 scrapes away the rainwater on the film 3. The movement of the cleaning sleeve 18 also drives the rotating shaft 1. The movement of the gear 11 causes the rack 12 to rotate, which in turn drives the shaft 13 to rotate, thereby driving the cleaning roller 14 to rotate and clean the residual rainwater on the surface of the film 3. When the telescopic motor 6 drives the push rod 5 to move downward through the connecting rod, the push rod 5 no longer supports the connecting rod 4. Under the action of gravity, the connecting rod 4 and the mounting bracket 2 rotate downward around the support leg 1. When the telescopic motor 6 drives the push rod 5 to move downward through the connecting rod, it returns to the initial position. The film 3 has a shape that is low in the middle and high on both sides. Under the action of gravity, the rainwater and the cleaning components move towards the middle of the film 3. Then, the rainwater accumulates and causes the film 3 to deform and squeeze the extrusion plate 9, causing the telescopic motor 6 to work again. The film 3 repeats the process of accumulating and discharging rainwater, avoiding the problem that the film 3 is easily crushed by rainwater.
