Description

Technical Field

[0001] This utility model relates to the field of water canal filtration technology, and more specifically, to a water canal filtration device for agricultural non-point source pollution. Background Technology

[0002] In agricultural production, excessive application of chemical fertilizers and pesticides, as well as pollutants such as silt and organic debris carried by farmland surface runoff, can easily enter irrigation canals as non-point source pollution, leading to a decline in canal water quality. This not only affects the safety of agricultural irrigation water but may also damage the downstream aquatic ecosystem. Currently, existing filtration devices for agricultural non-point source pollution irrigation canals mostly use a single filter structure, which can only intercept pollutants of specific particle sizes in the water, resulting in limited filtration efficiency and difficulty in achieving graded filtration to address pollutant particles of different sizes. Furthermore, these filtration devices generally lack effective self-cleaning mechanisms; after long-term use, the filter surface easily accumulates a large amount of pollutants, causing blockage and requiring frequent manual disassembly and cleaning. This not only increases the labor intensity of operators but also interrupts filtration operations during cleaning, affecting the continuous purification efficiency of the canal water. In addition, some core components of filtration devices (such as guide and transmission structures) use fixed connections. When components wear out or malfunction, the disassembly and replacement process is complex, resulting in poor maintenance convenience and further reducing the overall performance and lifespan of the device, making it difficult to meet the long-term, efficient, and stable filtration requirements of agricultural non-point source pollution irrigation canals. Utility Model Content

[0003] To overcome the above shortcomings, this utility model provides a filtration device for agricultural non-point source pollution water channels. It aims to improve upon the existing filtration devices for agricultural non-point source pollution water channels, which mostly adopt a single filter structure and can only intercept pollutants of a specific particle size in the water. The filtration effect is limited and it is difficult to achieve graded filtration to deal with pollutant particles of different sizes.

[0004] This utility model is implemented as follows: an agricultural non-point source pollution water channel filtration device includes a U-shaped support base, filter plates symmetrically installed inside the support base, vertical plates symmetrically fixedly installed at both ends of the filter plates, side plates symmetrically fixedly installed on one side of the vertical plates, a first guide rod fixedly installed between the two side plates, a sliding plate slidably installed on the first guide rod, a brush cooperating with the filter plate installed on one side of the sliding plate, a support column rotatably installed at the bottom of the inner wall of the support base, a positioning box fixedly installed at the top of the support column, guide frames symmetrically fixedly installed on both sides of the positioning box, a guide column cooperating with the guide frame fixedly installed at the top of the sliding plate, and a drive assembly installed at the top of the positioning box.

[0005] In a preferred embodiment of this utility model, the mesh openings of the two filter plates are different, positioning strips are symmetrically fixed on both sides of the inner wall of the support base, and a positioning groove matching the positioning strip is provided on one side of the vertical plate. The mesh openings of the two filter plates gradually decrease in size along the direction of water flow.

[0006] In a preferred embodiment of this utility model, inserts are symmetrically fixedly installed on both sides of the positioning box, the guide frame is U-shaped and has slots at both ends that match the inserts, and the inserts are slidably connected to the inner wall of the slots.

[0007] In a preferred embodiment of this utility model, the insert is hollow and its interior communicates with the inner wall of the positioning box. A partition is fixedly installed on the inner wall of the positioning box, and a strip plate is slidably installed on the inner wall of the insert. One end of the strip plate extends into the positioning box, and a spring is fixedly installed between the strip plate and the partition. A push block and an insert block are fixedly installed on one side of the strip plate. One end of the push block slides through the positioning box and extends to the outside. One end of the insert block slides through the insert and is inserted into one side of the guide frame. The guide frame has symmetrically arranged insertion holes that match the insert blocks on both sides, and one end of the insert block is inclined.

[0008] In a preferred embodiment of this utility model, a second guide rod is fixedly installed between the positioning box and the two sides of the inner wall of the insert, and the strip plate is slidably installed on the second guide rod.

[0009] In a preferred embodiment of this utility model, the driving assembly includes a U-shaped frame and a servo motor. The U-shaped frame is fixedly mounted on the top of the support base, and the servo motor is fixedly mounted on the top of the U-shaped frame. The output end of the servo motor passes through the U-shaped frame and is fixedly mounted on a support plate. A centrifugal shaft is fixedly mounted on the bottom of the support plate. A quadrangular prism is fixedly mounted between the two sides of the inner wall of the U-shaped frame. A first support frame is slidably mounted on the quadrangular prism. A second support frame is fixedly mounted on the top of the first support frame. The centrifugal shaft is slidably connected to the inner wall of the second support frame. The first support frame and the positioning box are driven by a gear set. The first support frame and the second support frame are arranged perpendicular to each other. The support plate is rotatably connected to the top of the inner wall of the U-shaped frame.

[0010] In a preferred embodiment of this utility model, the quadrangular prism is disposed at the center of the first support frame.

[0011] In a preferred embodiment of this utility model, the gear set includes a rack and a gear, a rotating shaft is fixedly installed at the top of the positioning box, the gear is fixedly installed on the rotating shaft, the rack is fixedly installed at the bottom of the first support frame, the rack meshes with the gear, and the rotating shaft coincides with the axis of the support column.

[0012] The beneficial effects of this utility model are: The device exhibits significant tiered filtration effects. It features two filter plates with different mesh sizes symmetrically installed within a U-shaped support base. The mesh size of the filter plates decreases sequentially along the water flow direction. This allows the larger mesh plate to intercept large pollutants such as dead branches and large pieces of silt, while the smaller mesh plate retains fine sand, organic debris, and other small particulate impurities. This tiered filtration effectively addresses agricultural non-point source pollution in water bodies, significantly improving filtration precision and purification efficiency. It effectively safeguards the water quality of irrigation canals and meets the water needs of agricultural irrigation and downstream ecological environments.

[0013] Equipped with an automatic cleaning function, it eliminates the need for frequent manual cleaning. Through a drive assembly consisting of a servo motor, support plate, centrifugal shaft, first support frame, second support frame, rack, gear, etc., it can drive the positioning box to rotate forward and backward around the support column. Then, through the cooperation of the guide frame and the guide column, it drives the slide plate to slide back and forth along the first guide rod, so that the brush on one side of the slide plate repeatedly wipes the surface of the filter plate, promptly cleaning the pollutants attached to the filter plate, effectively preventing the filter plate from clogging, ensuring the continuous and stable operation of the filtration, reducing the labor intensity of operators, and improving the operating efficiency of the device.

[0014] The components are easy to assemble and maintain. The inserts on both sides of the positioning box slide into the slots of the guide frame. Combined with the elastic locking structure of springs, strip plates, and inserts, a stable connection between the guide frame and the positioning box can be quickly achieved. Disassembly can be completed by pushing the push block to release the lock. At the same time, the filter plate is installed by the positioning groove of the vertical plate and the positioning strip of the support base, which facilitates quick disassembly and replacement. This greatly reduces the difficulty of component maintenance and replacement, extends the overall service life of the device, and improves the convenience and economy of use.

[0015] The structure operates stably and reliably. The quadrangular prism in the drive assembly is located at the center of the first support frame, providing stable guidance for the reciprocating sliding of the first support frame. The second guide rod guides the sliding of the strip plate, ensuring that the insert block is accurately inserted into the insertion hole of the guide frame. The rotating shaft and the support column shaft coincide, ensuring that the positioning box rotates stably when the gear and rack mesh. The precise coordination and guiding design of each component effectively improve the overall stability and reliability of the device and reduce the probability of failure.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Please see Figures 1-4This utility model provides a technical solution: a water filtration device for agricultural non-point source pollution, comprising a U-shaped support base 110, filter plates 120 symmetrically installed inside the support base 110, vertical plates 121 symmetrically fixedly installed at both ends of the filter plates 120, side plates 122 symmetrically fixedly installed on one side of the vertical plates 121, a first guide rod 123 fixedly installed between the two side plates 122, a sliding plate 124 slidably installed on the first guide rod 123, a brush 125 cooperating with the filter plates 120 installed on one side of the sliding plate 124, a support column 130 rotatably installed at the bottom of the inner wall of the support base 110, a positioning box 131 fixedly installed at the top of the support column 130, guide frames 132 symmetrically fixedly installed on both sides of the positioning box 131, a guide column 133 cooperating with the guide frame 132 fixedly installed at the top of the sliding plate 124, and a drive assembly installed at the top of the positioning box 131.

[0021] In some specific implementation schemes, the mesh openings of the two filter plates 120 are different. Positioning strips 126 are symmetrically fixed on both sides of the inner wall of the support base 110. A positioning groove matching the positioning strips 126 is provided on one side of the vertical plate 121. The mesh openings of the two filter plates 120 gradually decrease in size along the direction of water flow, which can realize the graded filtration of agricultural non-point source pollutants. First, the filter plate 120 with a larger mesh opening intercepts large-volume pollutants such as dead branches and large pieces of mud and sand. Then, the filter plate 120 with a smaller mesh opening intercepts small particulate impurities such as fine sand and organic debris, thereby improving the filtration accuracy and purification effect.

[0022] Please see Figure 4 and Figure 5 The positioning box 131 has symmetrically fixed inserts 134 on both sides. The guide frame 132 is U-shaped and has slots at both ends that match the inserts 134. The inserts 134 are slidably connected to the inner walls of the slots. Initial assembly can be completed quickly without the need for complicated tools, simplifying the component installation process. At the same time, the sliding connection method also facilitates subsequent position adjustment or disassembly and maintenance of the guide frame 132, improving the convenience of device assembly and maintenance.

[0023] In some specific implementations, the insert 134 is hollow and its interior is connected to the inner wall of the positioning box 131. A partition 140 is fixedly installed on the inner wall of the positioning box 131. A strip plate 141 is slidably installed on the inner wall of the insert 134. One end of the strip plate 141 extends into the positioning box 131, and a spring 142 is fixedly installed between the strip plate 141 and the partition 140. A push block 143 and an insert block 144 are fixedly installed on one side of the strip plate 141. One end of the push block 143 slides through the positioning box 131 and extends to the outside. One end of the insert block 144 slides through the insert 134 and is inserted into one side of the guide frame 132. The guide frame 132 has symmetrically arranged insertion holes that match the insert block 144 on both sides. One end of the insert block 144 is inclined. The insertion block 144 is tilted at one end, which makes it easier for the guide frame 132 to squeeze the insertion block 144 to temporarily retract during assembly, reducing the difficulty of assembly; when disassembly is required, pushing the push block 143 can drive the insertion block 144 out of the insertion hole, realizing quick disassembly and further improving the flexibility of component disassembly and assembly and the convenience of maintenance.

[0024] In some specific implementations, a second guide rod 145 is fixedly installed between the inner walls of the positioning box 131 and the insert 134, and the strip plate 141 is slidably mounted on the second guide rod 145. This provides precise guidance for the strip plate 141 slidably mounted on it, preventing the strip plate 141 from shifting or getting stuck during sliding. This ensures that the strip plate 141 drives the insert block 144 to stably and accurately insert into or disengage from the insertion hole of the guide frame 132, ensuring the smoothness of the connection or disassembly between the guide frame 132 and the positioning box 131, and improving the reliability of the connection structure of the device components.

[0025] Please see Figure 6 and Figure 7 The drive assembly includes a U-shaped frame 150 and a servo motor 151. The U-shaped frame 150 is fixedly mounted on the top of the support base 110, and the servo motor 151 is fixedly mounted on the top of the U-shaped frame 150. The output end of the servo motor 151 passes through the U-shaped frame 150 and is fixedly mounted on a support plate 152. A centrifugal shaft 153 is fixedly mounted on the bottom of the support plate 152. A quadrangular prism 154 is fixedly mounted between the two sides of the inner wall of the U-shaped frame 150. A first support frame 155 is slidably mounted on the quadrangular prism 154. A second support frame 156 is fixedly mounted on the top of the first support frame 155. The centrifugal shaft 153 is slidably connected to the inner wall of the second support frame 156. The first support frame 155 and the positioning box 131 are driven by a gear set. The first support frame 155 and the second support frame 156 are set perpendicular to each other. The support plate 152 is rotatably connected to the top of the inner wall of the U-shaped frame 150. The quadrangular prism 154 is located at the center of the first support frame 155.

[0026] In some specific implementations, the gear set includes a rack 157 and a gear 158. A rotating shaft 159 is fixedly installed at the top of the positioning box 131, and a gear 158 is fixedly installed on the rotating shaft 159. A rack 157 is fixedly installed at the bottom of the first support frame 155. The rack 157 and the gear 158 mesh with each other. The rotating shaft 159 coincides with the axis of the support column 130, ensuring that the positioning box 131 rotates concentrically around the support column 130, avoiding eccentric offset when the positioning box 131 rotates, ensuring that the guide frame 132 and the guide column 133 are precisely matched, so that the slide plate 124 drives the brush 125 to slide stably along the filter plate 120, improving the stability and cleaning efficiency of the cleaning operation.

[0027] Working principle: This agricultural non-point source pollution water filtration device uses a U-shaped support base 110 as its basic load-bearing structure. It first achieves preliminary purification of agricultural non-point source polluted water through dual filtration, and then uses a drive component to drive the cleaning mechanism. It also has convenient component assembly and positioning functions. The specific working process is as follows: In the filtration stage, the filter plates 120 symmetrically installed inside the support base 110 are the core filtration components. Following the water flow direction, the mesh openings of the two filter plates 120 gradually decrease in size. The water first passes through the filter plate 120 with the larger mesh opening to intercept larger pollutants (such as dead branches, large pieces of silt, etc.), and then flows through the filter plate 120 with the smaller mesh opening to intercept smaller particles of impurities (such as fine sand, organic debris, etc.), thus achieving graded filtration and improving the filtration effect. The positioning strips 126 symmetrically fixed on both sides of the inner wall of the support base 110 cooperate with the positioning grooves on one side of the vertical plates 121 at both ends of the filter plate 120 to ensure that the filter plate 120 is stably installed inside the support base 110 and to prevent the filter plate 120 from shifting due to water flow impact.

[0028] In the cleaning process, the device relies on a drive assembly for power. A servo motor 151 in the drive assembly is fixed to a U-shaped frame 150 at the top of the support base 110. After the servo motor 151 starts, its output drives the support plate 152 to rotate, causing the centrifugal shaft 153 at the bottom of the support plate 152 to rotate in a circular motion. Since the centrifugal shaft 153 is slidably connected to the inner wall of the second support frame 156 at the top of the first support frame 155, and the first support frame 155 is slidably mounted on a quadrangular prism 154 between the two sides of the inner wall of the U-shaped frame 150 (the quadrangular prism 154 is located at the center of the first support frame 155 to ensure smooth sliding), the circular motion of the centrifugal shaft 153 can be converted into the reciprocating linear motion of the first support frame 155 along the quadrangular prism 154. Furthermore, because the rack 157 at the bottom of the first support frame 155 meshes with the gear 158 on the rotating shaft 159 at the top of the positioning box 131 (the rotating shaft 159 and the support...), the centrifugal shaft 153's circular motion can be converted into the reciprocating linear motion of the first support frame 155 along the quadrangular prism 154. The support column 130, which is rotatably mounted on the bottom of the inner wall of the support base 110, has the same axis. Therefore, the reciprocating linear motion of the first support frame 155 can drive the gear 158 to rotate forward and backward, and then drive the positioning box 131 to rotate forward and backward around the support column 130 through the rotating shaft 159. The guide frames 132, which are symmetrically fixed on both sides of the positioning box 131, move synchronously with the positioning box 131. The guide column 133 at the top of the slide plate 124 cooperates with the guide frame 132, and the slide plate 124 is slidably mounted on the first guide rod 123 between the two side plates 122 (the side plates 122 are fixed to one side of the vertical plate 121). The movement of the guide frame 132 will drive the guide column 133 to drive the slide plate 124 to slide back and forth along the first guide rod 123. Finally, the brush 125 on one side of the slide plate 124 will repeatedly wipe the surface of the filter plate 120, clean the pollutants attached to the filter plate 120, prevent the filter plate 120 from clogging, and ensure the filtration efficiency.

[0029] In the component assembly and positioning stage, the inserts 134 on both sides of the positioning box 131 are slidably connected to the slots at both ends of the guide frame 132, providing initial positioning for the assembly of the guide frame 132 and the positioning box 131. The inserts 134 are hollow and communicate with the inner wall of the positioning box 131. A spring 142 is fixed between the partition 140 fixed to the inner wall of the positioning box 131 and the strip plate 141 slidably installed on the inner wall of the inserts 134. Under the elastic force of the spring 142, the strip plate 141 will drive the insert block 144 on one side to slide through the insert 134 and insert into the insertion hole on one side of the guide frame 132, thereby stabilizing the guide frame 132 and the positioning box 131. The connection (one end of the insert 144 is inclined to facilitate the temporary retraction of the insert 144 by the guide frame 132 during assembly); the second guide rod 145 fixed between the inner walls of the positioning box 131 and the insert 134 guides the sliding of the strip plate 141, ensuring that the insert 144 is accurately inserted into the insertion hole; when the guide frame 132 needs to be disassembled, push the push block 143 on one side of the strip plate 141 (one end of the push block 143 extends to the outside of the positioning box 131), which can drive the strip plate 141 to compress the spring 142, so that the insert 144 can be disengaged from the insertion hole, thus separating the guide frame 132 from the positioning box 131, which facilitates the maintenance and replacement of the components.

[0030] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
