Description

A greenhouse rainwater collection, purification and recycling device Technical Field

[0001] This utility model relates to the field of rainwater harvesting, and in particular to a rainwater harvesting, purification and recycling device for greenhouses. Background Technology

[0002] In the development of modern agriculture, greenhouses, as important agricultural production facilities, provide a stable growing environment for crops such as vegetables and flowers, effectively improving crop yield and quality. However, with the increasingly severe water shortage problem and the urgent need for green and sustainable agricultural development, how to efficiently utilize natural resources has become a key issue in agricultural production. Rainwater, as a clean and renewable water resource, can be collected and recycled, which can not only alleviate the pressure on agricultural water use but also reduce production costs, aligning with the green and environmentally friendly development concept of modern agriculture.

[0003] Currently, rainwater is mainly collected by setting up simple collection troughs and storage tanks on the outside of the greenhouse, and then filtered before being used for irrigation. This type of collection device has the following disadvantages: First, most existing rainwater collection methods rely on the film on the greenhouse or increase the area of ​​the collection port, which greatly reduces the collection efficiency of rainwater and lacks a flexible flow guiding structure. In case of heavy rain, it is impossible to collect rainwater effectively in time. Second, in terms of filter installation, most methods simply place the filter directly on top of the storage tank, which cannot guarantee the stability of the filter, or fix the filter with bolts, which is very inconvenient for staff to maintain and replace the filter. In view of this technical problem, this application proposes a greenhouse rainwater collection, purification and recycling device. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a greenhouse rainwater collection, purification, and recycling device. Through the cooperation of components such as a rotating rod, protrusions, a fixed shell, a moving plate, and springs, it enables rapid positioning and disassembly of the filter plates. When cleaning debris from the filter plates, a brush can be used to sweep it away from the slope. When maintaining or replacing the filter plates, rotating the rotating rod releases the protrusions from their position, allowing the filter plates to be removed. This ensures secure installation of the filter plates while improving the efficiency of installation and disassembly. By hanging the guide cloth on the hook and turning the handwheel, the pull rope is wound up, moving the slider. The slider, through the hook, unfolds the rainproof cloth, allowing it to guide rainwater into the guide channel. The rainwater then flows through a connecting pipe into a water storage tank, facilitating subsequent irrigation. This significantly improves rainwater utilization, reduces irrigation costs, and provides convenience for greenhouse cultivation.

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

[0006] A greenhouse rainwater collection, purification, and recycling device includes a frame. A fixed rod is fixedly connected to the top of the frame. A slider is slidably connected to the middle of the fixed rod. Hooks are fixedly connected to the outer walls of both the slider and the left and right ends of the fixed rod. A rainproof cloth is provided on the side of the hook away from the slider. Pull ropes are fixedly connected to both the front and rear ends of the slider. A handwheel is connected to the end of the pull rope away from the slider through multiple pulleys. The handwheel is rotatably connected to the frame. A guide channel is fixedly connected to both the left and right ends of the frame. A water storage tank is provided at the bottom of the guide channel. A limit frame is fixedly connected to the inner wall of the water storage tank. A filter plate is connected to the top of the limit frame through a limit component.

[0007] Furthermore, the limiting component connection includes a fixing strip fixedly connected to the top of the limiting frame, a rotating rod rotatably connected to the top middle of the fixing strip, and a protrusion fixedly connected to the outer wall of the rotating rod.

[0008] Furthermore, a fixed shell is provided on the outer wall of the middle part of the rotating rod, and a spring is provided on the inner wall of the fixed shell. One end of the spring is connected to the fixed shell, and the other end of the spring is connected to the outer wall of the rotating rod.

[0009] Furthermore, each of the four corners of the limiting frame is slidably connected to a sliding rod, and the top of the sliding rod is fixedly connected to a movable plate.

[0010] Furthermore, a spring is fitted on the outer wall of the slide rod, one end of the spring is connected to the bottom of the movable plate, and the other end of the spring is connected to the limiting frame.

[0011] Furthermore, a pump body is connected to the rear of the water storage tank via a connecting pipe.

[0012] Furthermore, the guide channels at the left and right ends are connected by connecting pipes.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the filter plate can be quickly positioned and disassembled by the cooperation of components such as the rotating rod, protrusion, fixed shell, moving plate and spring. When cleaning the filter plate, the debris can be swept out from the slope with a brush. When maintaining or replacing the filter plate, the rotating rod is rotated so that the protrusion releases the limiting position on the filter plate, and the filter plate can be removed. This not only ensures that the filter plate is installed firmly, but also improves the efficiency of filter plate installation and disassembly.

[0015] 2. In this utility model, by hanging the guide cloth on the hook, turning the handwheel can retract the pull rope, which drives the slider to move. The slider unfolds the rainproof cloth through the hook, which greatly improves the efficiency of rainwater collection. The rainproof cloth can guide the rainwater into the guide channel, and then into the water storage tank through the connecting pipe, which facilitates subsequent irrigation. This greatly improves the rainwater utilization rate, reduces irrigation costs, and provides convenience for greenhouse planting. Attached Figure Description

[0023] 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.

[0024] Referring to Figures 1-3, one embodiment of this utility model provides a greenhouse rainwater collection, purification, and recycling device, including a frame 1 covering the outside of the greenhouse. A fixed rod 3 is fixedly connected to the top of the frame 1, and a slider 10 is slidably connected to the middle of the fixed rod 3. The slider 10 can slide within the fixed rod 3. Hooks 11 are fixedly connected to the outer walls of both ends of the slider 10 and the fixed rod 3, allowing the slider 10 to move along with the hooks 11. A rainproof cloth 4 is provided on the side of the hooks 11 away from the slider 10, with a support rod inside the rainproof cloth 4 to ensure its overall stability. The outer wall of the rainproof cloth 4 is coated with a hydrophobic layer, guiding rainwater into a diversion channel 2. Pull ropes 5 are fixedly connected to both ends of the slider 10. A handwheel 6 is connected to the end of the pull rope 5 away from the slider 10 via multiple pulleys. The handwheel 6 is rotatably connected to the frame 1, allowing the slider 10 to be rotated. The pull rope 5 is wound up, which in turn causes the pull rope 5 to pull the slider 10 to move. Both ends of the frame 1 are fixedly connected to guide channels 2, which are inclined forward. A water storage tank 7 is located at the bottom of the guide channel 2, and a ramp is provided on the front side of the water storage tank 7. A limit frame 13 is fixedly connected to the inner wall of the water storage tank 7, which supports the filter plate 8. The filter plate 8 is located at the top of the limit frame 13, and the front end of the filter plate 8 has an opening with dimensions matching the fixing strip 12. The corresponding through groove, the top of the limiting frame 13 is fixedly connected to the fixing strip 12, the top middle of the fixing strip 12 is rotatably connected to the rotating rod 17, the outer wall of the rotating rod 17 is fixedly connected to the protrusion 18, by rotating the rotating rod 17 can move the protrusion 18. When the protrusion 18 is inside the fixing strip 12, it cannot limit the filter plate 8. When the protrusion 18 is outside the fixing strip 12 and above the filter plate 8, it can limit the filter plate 8.

[0025] Referring to Figures 3-5, a fixed shell 20 is provided on the outer wall of the middle part of the rotating rod 17, and a spring-loaded spring 19 is provided on the inner wall of the fixed shell 20. One end of the spring-loaded spring 19 is connected to the fixed shell 20, and the other end of the spring-loaded spring 19 is connected to the outer wall of the rotating rod 17. By providing the spring-loaded spring 19, the protrusion 18 can be automatically reset, thereby limiting the position of the filter plate 8. Sliding rods 14 are slidably connected at the four corners of the limiting frame 13, and a moving plate 16 is fixedly connected to the top of the sliding rod 14. A spring 15 is sleeved on the outer wall of the sliding rod 14. One end of the spring 15 is connected to the bottom of the moving plate 16, and the other end of the spring 15 is connected to the limiting frame 13. When installing the filter plate 8, by pressing the filter plate 8 downward, the filter plate 8 pushes the moving plate 16 downward, and the moving plate 16 compresses the spring 15. After the filter plate 8 is installed, the reaction force of the spring 15 can improve the stability of the filter plate 8 installation. The rear of the water storage tank 7 is connected to a pump body 9 via a connecting pipe. The output end of the pump body 9 is connected to an irrigation device, which includes water pipes and nozzles. The pump body 9 can transport water from the water storage tank 7 to the irrigation device, which then irrigates the vegetables in the greenhouse. The guide channels 2 at the left and right ends are connected by connecting pipes.

[0026] Working principle: First, hang one side of the rainproof cloth 4 on the hook 11 on the outer wall of the slider 10, and then hang the other side of the rainproof cloth 4 on the hook 11 on the outer wall of the fixing rod 3. By turning the handwheel 6, the pull rope 5 can be wound up, which in turn causes the pull rope 5 to pull the slider 10 to move, thereby unfolding or retracting the rainproof cloth 4. By setting the rainproof cloth 4, the greenhouse can be covered, allowing rainwater to flow along the rainproof cloth 4 into the guide channel 2. The rainwater in the guide channel 2 flows into the water storage tank 7 through the connecting pipe and is filtered by the filter plate 8. Then, the pump body 9 can irrigate the vegetables in the greenhouse. When it is necessary to clean the debris on the filter plate 8, the debris on the filter plate 8 can be removed from the slope at the front end of the water storage tank 7 by using a brush. When the filter plate 8 needs maintenance or replacement, first rotate the rotating rod 17, so that the rotating rod 17 rotates with the protrusion 18 and compresses the fixed shell 20, so that the protrusion 18 rotates away from the top of the filter plate 8, releasing the protrusion 18 from limiting the filter plate 8. Then remove the filter plate 8. When installing the filter plate 8, first place the filter plate 8 on the top of the limiting frame 13, then press the filter plate 8 down, so that the filter plate 8 pushes the moving plate 16 down, thereby compressing the spring 15. Then, the spring 19 returns to its original position, so that the protrusion 18 can rotate to the top of the filter plate 8, thereby limiting the filter plate 8. This ensures the stability of the filter plate 8 and improves the efficiency of the filter plate 8 installation.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
