Description

Technical Field

[0001] The utility model relates to the field of agricultural water conservancy, in particular to a filtering device for agricultural rainwater collection. Background Art

[0002] Rainwater collection can be used for agricultural irrigation, reducing the dependence on groundwater, saving water resources, and rainwater itself contains natural nutrients, which helps to improve the growth quality of crops.

[0003] Since rainwater will converge into running water due to the influence of water channels, currently, filter nets are generally set in agricultural water conservancy water channels to block floating debris in the running water. However, the long-term accumulation of floating debris on the filter net will affect the normal passage of running water. Therefore, it is necessary to regularly manually remove the filter net and use hand tools to clean the floating debris on the filter net, but such cleaning is rather troublesome. Content of the Utility Model

[0004] In order to overcome the shortcoming that the filter net is blocked by floating debris in the prior art, the utility model provides a filtering device for agricultural rainwater collection, which can timely lift the floating debris on the filter net when there is a large accumulation of impurities.

[0005] The technical solution is as follows: A filtering device for agricultural rainwater collection includes a filtering frame. Two vertical grooves are opened on the filtering frame. Two trapezoidal grooves are opened on one side of the filtering frame. Two guiding columns are fixedly connected to the filtering frame. Each guiding column is slidably connected with a lifting block. The lifting block is slidably connected with the vertical groove of the filtering frame. A compression spring is connected between the filtering frame and the lifting block. A fixed lifting net plate is fixedly connected to the bottom side of the lifting block. Two fixed limiting blocks are fixedly connected to the filtering frame. A lever is slidably connected to each lifting block. A return spring is connected between the lever and the lifting block. Two supporting plates are fixedly connected to one side of the filtering frame. A lifting inclined rod is slidably connected to the supporting plate. An air floatation tube is fixedly connected between the two lifting inclined rods. Fixed cylinders are fixedly connected to both levers.

[0006] Optionally, it further includes the fixed lifting net plate, and the inside of the fixed lifting net plate is of a net structure.

[0007] Optionally, it further includes an air floatation tube, and gas is stored inside the air floatation tube.

[0008] Optionally, it further includes an inclined surface scraping plate, and the inclined surface scraping plate is fixedly connected to the fixed lifting net plate.

[0009] Compared with the prior art, the utility model has the following advantages: 1. When the water level of the flowing water rises to a certain height, the water will drive the air flotation pipe and the lifting inclined rod to move upward together. The upward movement of the lifting inclined rod pushes the fixed cylinder and the lever to move away from the filter frame, the return spring is stretched, the fixed limit block no longer limits the lever, and the lever no longer limits the lifting block. Under the action of the compression spring, the lifting block drives the fixed lifting net plate, the lever and the return spring to quickly move upward along the guide column and the vertical groove opened in the filter frame, so that the fixed lifting net plate moves upward to pick up the impurities and fallen leaves blocked by the filter frame from the water, so that the impurities and fallen leaves on the filter frame no longer block the flowing water, thereby enabling the flowing water to pass through the filter frame normally.

[0010] 2. The lifting block drives the fixed lifting net plate and the inclined surface scraper to move upward together, and the inclined surface scraper scrapes off the impurities and fallen leaves attached to the filter frame, making the filtering effect of the filter frame better.

Detailed Embodiment

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Embodiment 1: A filtering device for agricultural rainwater collection, as Figures 1-5 shown, which includes a filtering frame 1. Two vertical slots are opened in the filtering frame 1. Two trapezoidal grooves are opened on one side of the filtering frame 1. Two guiding columns 2 are welded on the filtering frame 1. Each guiding column 2 is slidably connected with a lifting block 3. The lifting block 3 is slidably connected with the vertical slot of the filtering frame 1. A compression spring 4 is connected between the filtering frame 1 and the lifting block 3. A fixed lifting mesh plate 5 is welded on one side of the bottom of the lifting block 3. The inside of the fixed lifting mesh plate 5 is a mesh structure. The fixed lifting mesh plate 5 is used to pick up the filtered impurities and fallen leaves. Two fixed limiting blocks 6 are welded on the filtering frame 1. A shifting rod 7 is slidably connected to each lifting block 3. A return spring 8 is connected between the shifting rod 7 and the lifting block 3. Two supporting plates 9 are welded on one side of the filtering frame 1. A lifting inclined rod 10 is slidably connected to the supporting plate 9. An air flotation tube 11 is fixedly connected between the two lifting inclined rods 10. Fixed cylinders 12 are welded on the two shifting rods 7.

[0019] At first, the fixed limit block 6 limits the lever 7, the lever 7 limits the lifting block 3, and the compression spring 4 is in a compressed state. The staff installs this device inside the water channel, making the fixed lifting mesh plate 5 in close contact with the bottom of the water channel. When it rains, the rainwater converging in the water channel forms flowing water, which will drive the impurities and fallen leaves in the water channel towards the filter frame 1. The filter frame 1 filters the impurities and fallen leaves in the water. As time goes by, when the filter frame 1 accumulates a certain amount of impurities and fallen leaves, the flowing water will be blocked by the impurities and fallen leaves, so that the water no longer passes through the filter frame 1, and the water level of the flowing water in the water channel rises. When the water level of the flowing water rises to a certain height, the water will drive the air flotation pipe 11 and the lifting inclined rod 10 to move upward together. The upward movement of the lifting inclined rod 10 pushes the fixed cylinder 12 and the lever 7 to move away from the filter frame 1, and the return spring 8 is stretched. The fixed limit block 6 no longer limits the lever 7, and the lever 7 no longer limits the lifting block 3. Under the action of the compression spring 4, the lifting block 3 drives the fixed lifting mesh plate 5, the lever 7 and the return spring 8 to quickly move upward along the guide column 2 and the vertical groove opened in the filter frame 1, so that the fixed lifting mesh plate 5 moves upward to lift the impurities and fallen leaves blocking the filter frame 1 from the water, so that the impurities and fallen leaves on the filter frame 1 no longer block the flowing water, so that the flowing water can pass through the filter frame 1 normally. When the lifting block 3 drives the fixed lifting mesh plate 5, the lever 7 and the return spring 8 to move to a certain extent, the lever 7 is clamped into the trapezoidal groove of the filter frame 1 under the action of the return spring 8, and the lever 7 is limited by the trapezoidal groove of the filter frame 1, and then the lifting block 3 and the fixed lifting mesh plate 5 are limited by the lever 7. After that, the staff cleans the impurities and fallen leaves on the fixed lifting mesh plate 5. After cleaning, the lever 7 is pulled to move away from the trapezoidal groove, and the trapezoidal groove no longer limits the lever 7. Then, the lifting block 3 and the compression spring 4 are pushed downward to return to the initial state, and the fixed limit block 6 continues to block the lever 7.

[0020] Embodiment 2: On the basis of Embodiment 1, as Figure 2 shown, it further includes an inclined surface scraper 13. The inclined surface scraper 13 is welded on the fixed lifting mesh plate 5, and the inclined surface scraper 13 is used to scrape the impurities and fallen leaves on the filter frame 1.

[0021] When the lifting block 3 drives the fixed lifting mesh plate 5 to move upward together, the inclined surface scraper 13 also moves upward together with the fixed lifting mesh plate 5. The inclined surface scraper 13 scrapes off the impurities and fallen leaves attached to the filter frame 1, making the filtering effect of the filter frame 1 better.

[0022] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
