Description

Technical Field

[0001] This utility model relates to the field of farmland water conservancy technology, specifically to a debris filtration device for farmland water utilization channels. Background Technology

[0002] In agricultural irrigation projects, irrigation ditches are frequently used. Shrubs and weeds typically grow along the sides of these ditches, and leaves and branches from these plants fall into the ditches and flow with the water until they accumulate in front of the filters installed at intervals along the ditches. When too much debris accumulates in front of the filters, it can easily cause blockages, reducing the water flow after the filters and affecting the normal operation of the ditches. Currently, the filters in these ditches are cleaned manually. However, manual cleaning is not only labor-intensive but also carries the risk of injury from accumulated debris, especially in cold winter conditions. Therefore, manual cleaning is not very efficient. Utility Model Content

[0003] This utility model addresses the problem of high labor intensity and low cleaning efficiency caused by manual cleaning of filtration devices in small-scale farmland water conservancy projects when the canals are filled with debris. It provides a farmland water utilization debris filtration device that replaces manual cleaning, improves cleaning efficiency, and avoids the problem of high labor intensity caused by manual cleaning.

[0004] The technical solution adopted in this utility model is:

[0005] A device for filtering debris from irrigation canals in farmland is provided, comprising:

[0006] A fixed frame has first sliding grooves inside its opposite side walls; a first through groove communicating with the first sliding grooves is formed on the outer wall of the fixed frame; a first fixed frame is located inside the fixed frame and is slidably connected to the fixed frame through the first sliding grooves; a first filter screen is provided inside the first fixed frame; a first collecting plate is provided on the outer wall of the first fixed frame, and the outer wall of the first collecting plate is in sliding contact with the inner wall of the fixed frame; a lifting mechanism is provided on the outer wall of the fixed frame and is used to drive the first fixed frame to move up and down; a cleaning mechanism is provided on the outer wall of the fixed frame and is used to clean debris from the first collecting plate; an anchor rod is provided at the bottom of the fixed frame and is used to fix the fixed frame in the water channel.

[0013] Optionally, a collection box is also provided on the outer wall of the mounting frame for collecting debris cleaned from the first and second collection plates.

[0014] The beneficial effects of this utility model are:

[0015] By fixing the anchor rods at the bottom of the outer side of the fixed frame to the bottom of the water channel to prevent the fixed frame from swaying in the water channel, the lifting mechanism is then driven to position the first fixed frame at the bottom of the inner side of the fixed frame. After the water in the water channel has been flowing for a period of time, a large amount of debris has accumulated in front of the first filter screen in the first fixed frame.

[0030] The following disclosure provides many different embodiments or examples for implementing various structures of this invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this invention.

[0031] The embodiments of the utility model will now be described in detail with reference to the accompanying drawings.

[0032] Example

[0033] like Figure 1 As shown, this embodiment discloses a debris filtration device for farmland water utilization irrigation canals, comprising:

[0034] The fixing frame 1 has a first sliding groove 10 inside its opposite side walls; the outer wall of the fixing frame 1 has a first through groove 12 that communicates with the first sliding groove 10.

[0035] The first fixed frame 2 is located inside the fixed frame 1. The first fixed frame 2 is slidably connected to the fixed frame 1 via the first sliding groove 10. The first fixed frame 2 is provided with a first filter screen 20 inside.

[0036] The first collecting plate 21 is disposed on the outer wall surface of the first fixed frame 2, and the outer wall surface of the first collecting plate 21 is in sliding contact with the inner wall surface of the fixed frame 1.

[0037] The lifting mechanism is located on the outer wall of the fixed frame 1 and is used to drive the first fixed frame 2 to perform lifting and lowering movements;

[0038] The cleaning mechanism is located on the outer wall of the fixed frame 1 and is used to clean debris on the first collection plate 21;

[0039] Anchor bolt 16 is located at the bottom outer part of the fixing frame 1 and is used to fix the fixing frame 1 inside the water channel.

[0040] In use, the anchor rod 16 at the bottom of the outer side of the fixed frame 1 is fixed to the bottom of the inner side of the water channel to prevent the fixed frame 1 from shaking in the water channel. Then, the lifting mechanism is driven to make the first fixed frame 2 located at the bottom of the inner side of the fixed frame 1. After the water in the water channel flows for a period of time, a lot of debris accumulates in front of the first filter screen 20 in the first fixed frame 2. At this time, by driving the lifting mechanism, the working end of the lifting mechanism drives the first fixed frame 2 to move upward through the through groove on the fixed frame 1. The first fixed frame 2 slides along the sliding groove opened on the fixed frame 1. At the same time, the first collecting plate 21 on the outer wall of the first fixed frame 2 also moves upward with the first fixed frame 2. When the first collecting plate 21 moves upward, it will pick up the solid debris deposited in the water channel as well as the debris floating in the water and on the water surface. Next, the cleaning mechanism located on the outer wall of the fixed frame 1 is activated to remove the debris collected by the first collection plate 21 from the first collection plate 21. Finally, the lifting mechanism is driven to move the first fixed frame 2 down to the inner bottom of the fixed frame 1, and the first filter screen 20 in the first fixed frame 2 continues to filter the debris in the flowing water in the channel.

[0041] In one embodiment, such as Figure 1-3 As shown, the lifting mechanism includes:

[0042] The first housing 4 is disposed on the outer wall of the fixing frame 1, and the side wall of the first housing 4 is provided with a first opening 44 that communicates with the first through groove 12.

[0043] The first motor 40 is located inside the first housing 4. The output shaft of the first motor 40 is provided with a first gear 42. The first gear 42 is located in the communication between the first opening 44 and the first slide groove 10. Multiple first tooth grooves are opened on the outer wall surface of the first fixed frame 2. The first gear 42 meshes with the first fixed frame 2 through the multiple first tooth grooves.

[0044] In use, the lifting mechanism can drive the first fixed frame 2 to move up and down within the fixed frame 1. When the first fixed frame 2 moves upward, it can lift the second filter screen 30 from the water channel and then clean it to prevent clogging caused by prolonged use. When the first fixed frame 2 moves downward, after cleaning the second filter screen 30, it can be put back into the water channel to continue filtering impurities in the water. Specifically, the lifting mechanism includes a first housing 4, which is located on the outer wall of the fixed frame 1. A first motor 40 is installed inside the first housing 4, and a first gear 42 is installed on the output shaft of the first motor 40. Multiple first tooth grooves are opened on the side of the first fixed frame 2 facing the water channel, and the first gear 42 is connected to the first fixed frame 2 through the multiple first tooth grooves. When the first motor 40 is running, it drives its own output shaft to rotate, and the first gear 42 on the output shaft completes the lifting and lowering operation of the first filter screen 20 through the first tooth grooves on the outside of the first fixed frame 2.

[0045] In the above embodiment, the projection position of the lifting mechanism on the other side wall of the fixed frame 1 along the horizontal direction is above the cleaning mechanism, so as to avoid affecting the cleaning mechanism's cleaning of debris on the first collection plate 21.

[0046] In one embodiment, such as Figure 2 and Figure 3 As shown, a second sliding groove 11 is also provided inside the opposite side wall of the fixed frame 1, and a second through groove 13 communicating with the second sliding groove 11 is also provided on the outer wall surface of the fixed frame 1; a second fixed frame 3 is provided inside the fixed frame 1, and the second fixed frame 3 is slidably connected to the fixed frame 1 through the second sliding groove 11, and a second filter screen 30 is provided inside the second fixed frame 3.

[0047] In use, when the first collection plate 21 rises with the first fixed frame 2 to clean debris, debris still exists in the water channel. This debris, after the first filter screen 20 rises with the first fixed frame 2, will not be obstructed and will flow directly through the filtration device into the subsequent water channel, causing blockage. Therefore, a second filter screen 30 is installed in the fixed frame 1 for filtration. Specifically, a second through groove 13 is opened in the two side walls of the fixed frame 1 that are in contact with the inner wall of the water channel, and a second sliding groove 11 is opened on the inner wall surface of the opposite two side walls of the fixed frame 1. The second sliding groove 11 on one side of the inner wall of the fixed frame 1 is connected to the second through groove 13. A second fixed frame 3 is slidably connected inside the fixed frame 1. The second fixed frame 3 is slidably connected to the fixed frame 1 through the second sliding groove 11, and a second filter screen 30 is installed inside the second fixed frame 3. When the first fixed frame 2 moves upward, the debris in the flowing water in the channel will pass through the space between the bottom of the first fixed frame 2 and the inside of the fixed frame 1. The debris will be blocked by the second filter screen 30 on the second fixed frame 3 in the fixed frame 1, preventing the debris in the channel from passing through the space between the bottom of the first fixed frame 2 and the inside of the fixed frame 1 when cleaning the debris on the first collection plate 21, thus avoiding blockage in the channel later.

[0048] In one embodiment, such as Figure 2 and Figure 3 As shown, a second opening 45 communicating with the second through slot 13 is also provided on the side wall of the first housing 4; a second motor 41 is also provided inside the first housing 4, and a second gear 43 is provided on the output shaft of the second motor 41; a plurality of second tooth grooves are provided on the outer wall of the second fixed frame 3, and the second gear 43 meshes with the second fixed frame 3 through the plurality of second tooth grooves.

[0049] During use, if too much debris accumulates in front of the second filter screen 30, it needs to be cleaned to prevent clogging. Specifically, by operating the second motor 41, the output shaft of the second motor 41 rotates, driving the second gear 43 to rotate. The second gear 43, located at the connection between the second opening 45 and the second through groove 13, meshes with multiple second tooth grooves on the outer wall of the second fixed frame 3, causing the second fixed frame 3 to move upward, thus causing the second filter screen 30 connected to the second fixed frame 3 to float to the surface, allowing for cleaning of the second filter screen 30. It is worth noting that before cleaning the second filter screen 30, the debris in front of the second filter screen 30 must be removed to prevent the debris from continuing to flow into the subsequent water channel after the second filter screen 30 rises with the second fixed frame 3.

[0050] In one embodiment, such as Figure 2 and Figure 4 As shown, the cleaning organization:

[0051] The second box 5 is located on the outer wall of the fixing frame 1, and a third opening 52 is provided on the side wall of the second box 5;

[0052] The first telescopic rod 50 is located inside the second housing 5, with the telescopic end of the first telescopic rod 50 facing the third opening 52;

[0053] The first push plate 54 is located on the telescopic end of the first telescopic rod 50 and is used to clean up debris on the first collection plate 21.

[0054] In use, the cleaning mechanism can remove debris from the first collection plate 21, allowing the first collection plate 21 to continue collecting debris from the water channel. Specifically, a second box 5 is provided on the outer wall of the fixed frame 1 on the side opposite to where the first box 4 is located. A third opening 52 is opened on the side wall of the second box 5. A first telescopic rod 50 is provided inside the second box 5. The telescopic end of the first telescopic rod 50 extends and retracts toward the third opening 52, and a first push plate 54 is provided on the telescopic end of the first telescopic rod 50. The first push plate 54 can pass through the third opening 52 under the action of the first telescopic rod 50. When the first push plate 54 is pushed out of the third opening 52 by the first telescopic rod 50, the first collection plate 21, along with the moving first fixed frame 2, is on the same plane as the third opening 52. That is, the bottom of the first push plate 54 can slide on the top of the first collection plate 21, thereby cleaning away the debris retrieved from the first collection plate 21. It is worth noting that the outer wall of the side wall of the first collecting plate 21 not only slides in contact with the inner wall of the fixing frame 1, but also slides in contact with the inner wall of the water channel, so that when the first collecting plate 21 moves up and down, the debris on the first collecting plate 21 will not fall into the water channel from the gap between the first collecting plate 21 and the water channel.

[0055] In one embodiment, such as Figure 2 and Figure 4 As shown, a fourth opening 53 is also provided on the side wall of the second box 5; a second telescopic rod 51 is also provided inside the second box 5, the telescopic end of the second telescopic rod 51 faces the fourth opening 53, and a second push plate 55 is provided on the telescopic end of the second telescopic rod 51; a third through groove 14 is provided on the opposite side wall of the fixing frame 1 for the second push plate 55 to pass through.

[0056] When in use, the second telescopic rod 51 operates, causing the second push plate 55 on the telescopic end to move toward the fourth opening 53 opened on the second housing 5. The second push plate 55, passing through the fourth opening 53, continues to enter the interior of the fixed frame 1 through the third through groove 14 opened on the side wall of the fixed frame 1. After the first fixed frame 2 moves up, the debris floating on the water surface inside the fixed frame 1 can be pushed out through the third through groove 14 on the other side of the fixed frame 1, thus completing the cleaning of the debris.

[0057] In one embodiment, such as Figure 2-4 As shown, a second collecting plate 31 is provided on the outer wall surface of the second fixed frame 3.

[0058] When in use, the second collecting plate 31 can move with the second fixed frame 3 to scoop out the debris accumulated at the bottom of the water channel as well as the debris floating in the water and on the surface, making it easier to clean up the debris.

[0059] In one embodiment, such as Figure 1 and Figure 2 As shown, a collection box 6 is also provided on the outer wall of the fixing frame 1 for collecting the debris that has been cleaned from the first collection plate 21 and the second collection plate 31.

[0060] In use, the collection box 6 can collect debris cleaned from the first collection plate 21 and the second collection plate 31, preventing the cleaned debris from accumulating beside the ditch and then falling back into the ditch. Specifically, the collection box 6 is installed on the outer wall of the fixing frame 1, and the fixing frame 1 is installed on the outer wall of the first box body 4. The collection box 6 is located below the first box body 4, corresponding to the position where the cleaning mechanism cleans the first collection plate 21 and the second collection plate 31. The side wall of the collection box 6 has holes that allow debris on the first collection plate 21 and the second collection plate 31 to enter, facilitating the collection of debris from the first collection plate 21 and the second collection plate 31. It is worth noting that, since the second collecting plate 31 is located inside the fixed frame 1, after the second collecting plate 31 rises with the second fixed frame 3 until the top of the second collecting plate 31 is level with the bottom of the fixed frame 1 in the third through groove 14, the second telescopic rod 51 in the second box 5 operates. By driving the telescopic end, the second push plate 55 enters the interior of the fixed frame 1 through the third through groove 14 to clean the debris on the second collecting plate 31 and pushes the debris into the collecting box 6 through the third through groove 14 on the other side wall of the fixed frame 1.

[0061] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. Without conflict, the embodiments and features described in the embodiments of this application can be arbitrarily combined with each other. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
