Description

Technical Field

[0001] This invention relates to the field of water channel filtration technology, specifically a filtration and impurity removal device for water channels in water conservancy projects. Background Technology

[0002] In water conservancy projects, farmland irrigation often utilizes river water, which is channeled into farmland through ditches dug in the ground. Irrigation canals are artificially constructed waterways. Generally built of stone or cement, irrigation canals are important channel structures in water conservancy projects, serving functions such as water transport and agricultural irrigation. Irrigation canals are typically narrow in width and long in length. Water flowing through the canals easily carries impurities, requiring filtration and impurity removal devices to filter and remove these impurities.

[0003] In existing filtration and impurity removal devices, impurities tend to accumulate on the filter plates over time, affecting the filtration and impurity removal effect. Most existing devices lack a cleaning mechanism for the filter plates, requiring manual cleaning with tools. This lack of automatic scraping of the accumulated dirt is not only labor-intensive and inefficient but also increases the risk of accidents during cleaning, ultimately reducing the device's effectiveness. Therefore, we propose a filtration and impurity removal device for water conservancy engineering canals. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a filtration and impurity removal device for water conservancy engineering canals. This solves the problem that most existing filtration and impurity removal devices do not have a cleaning mechanism for the filter plates, and often require manual cleaning with tools. They cannot automatically scrape off the dirt attached to the filter plates, which not only results in high cleaning intensity and low efficiency, but also increases the danger of the dirt removal process.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A filtration and impurity removal device for irrigation canals in water conservancy projects includes a bottom support frame, a filter plate installed inside the bottom support frame, a cleaning frame slidably connected to the outer side of the bottom support frame, a pushing mechanism inside the cleaning frame, a fixing frame fixedly connected to the top of the bottom support frame, a rotating shaft rotatably connected inside the fixing frame via a bearing, winding rollers symmetrically fixedly sleeved on the outside of the rotating shaft, a connecting rope on the outside of the winding roller, and one end of the connecting rope fixedly connected to the cleaning frame.

[0007] The technical effect of adopting the above-mentioned further solution is that the L-shaped sliding seat is moved by the electric push rod, and the L-shaped sliding seat drives the push plate to slide through the connecting rod, thereby pushing the impurities inside the cleaning frame into the collection frame.

[0008] In a preferred embodiment, a bottom protective frame is fixedly connected to the bottom of the fixing frame, and guide wheels for guiding the connecting rope are symmetrically installed on the bottom of the fixing frame and on one side of the bottom protective frame.

[0010] In a preferred embodiment, the interior of the fixing frame is provided with a cable arrangement assembly for arranging the connecting ropes. The cable arrangement assembly includes mounting brackets symmetrically fixedly connected to the inner wall of the fixing frame. An adjusting block is slidably connected to the inner wall of the mounting bracket, and a guide ring is fixedly connected to the outside of the adjusting block.

[0011] The technical effect of adopting the above-mentioned further solution is that the guide ring is driven to slide along the inner wall of the mounting frame by the adjusting block, thereby performing the cable winding operation when the connecting rope is wound up.

[0012] In a preferred embodiment, a reciprocating lead screw is rotatably connected inside the mounting bracket via a bearing, the adjusting block is threadedly connected to the reciprocating lead screw, one end of the reciprocating lead screw extends outside the mounting bracket, and the reciprocating lead screw is connected to the rotating shaft via a second synchronous belt drive.

[0013] The technical effect of adopting the above-mentioned further solution is that the rotating shaft drives the reciprocating screw to rotate through the second synchronous belt, thereby causing the adjusting block to slide along the inner wall of the mounting bracket.

[0014] In a preferred embodiment, a first motor is fixedly connected to the outer side of the fixing frame, the output end of the first motor is fixedly connected to the rotating shaft, and a protective frame is fixedly connected to the outside of the fixing frame.

[0015] The technical effect of adopting the above-mentioned further solution is that the first motor drives the rotating shaft to rotate, and the first motor can be stored and protected by the protective frame.

[0016] In a preferred embodiment, the adjusting mechanism includes a first lead screw rotatably connected inside the connecting frame via a bearing, the adjusting rod being threadedly connected to the first lead screw, and the first lead screw being connected to the rotating shaft via a first synchronous belt drive.

[0017] The technical effect of adopting the above-mentioned further solution is that the rotating shaft drives the first lead screw to rotate through the first synchronous belt, and the rotation of the first lead screw drives the adjusting rod to move.

[0018] In a preferred embodiment, an L-shaped fixing seat is symmetrically fixedly connected to the bottom of the fixing frame, a connecting shaft is rotatably connected inside the L-shaped fixing seat, one end of the connecting shaft extends outside the L-shaped fixing seat, a plurality of flexible striking rods are fixedly connected in a ring array outside the L-shaped fixing seat, a second motor is fixedly connected to the outside of the L-shaped fixing seat, and the output end of the second motor is fixedly connected to the connecting shaft.

[0019] The technical effect of adopting the above-mentioned further solution is that the second motor drives the flexible striking rod to rotate through the connecting shaft, thereby striking the top of the push plate through the flexible striking rod, which facilitates the shaking off some impurities attached to the push plate and dropping them into the collection frame for collection.

[0020] This invention provides a filtration and impurity removal device for irrigation canals in water conservancy projects. Compared with the prior art, it has the following advantages: 1. The filtration and impurity removal device for water channels in this water conservancy project achieves the function of lifting and lowering the cleaning frame along the bottom support frame through the linkage design of the winding roller, connecting rope and cleaning frame, which facilitates the cleaning of the filter plate. Through the cooperation of the pushing mechanism, collection frame and pushing plate, the cleaned impurities can be collected and pushed out without the need for manual disassembly of the collection frame or manual cleaning of impurities.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figures 1 to 11 The present invention provides a technical solution: A filtration and impurity removal device for irrigation canals in water conservancy projects includes a bottom support frame 1, a filter plate 11 installed inside the bottom support frame 1, a cleaning frame 5 slidably connected to the outer side of the bottom support frame 1, a pushing mechanism inside the cleaning frame 5, a fixing frame 4 fixedly connected to the top of the bottom support frame 1, a rotating shaft 45 rotatably connected inside the fixing frame 4 via bearings, and winding rollers 47 symmetrically fixedly sleeved on the outside of the rotating shafts 45. A connecting rope 43 is provided on the outside of the winding rollers 47, and one end of the connecting rope 43 is fixedly connected to the cleaning frame 5. During use in the irrigation canals of water conservancy projects... The filter plate 11 can filter and remove impurities from the water in the channel. The rotating shaft 45 drives the winding roller 47 to rotate, thereby winding the connecting rope 43 and moving the cleaning frame 5 upward along the bottom support frame 1. The weight of the cleaning frame 5 is greater than its buoyancy. When the connecting rope 43 is released, it can move the cleaning frame 5 downward along the bottom support frame 1. The upward movement of the cleaning frame 5 can scrape and collect impurities on the outside of the filter plate 11. The pusher mechanism can push and collect the impurities collected inside the cleaning frame 5. A collection frame 2 is fixedly connected to the outer side of the bottom support frame 1, and a connecting frame 3 is fixedly connected to the outer side of the fixed frame 4. An adjusting rod 31 is slidably connected to the inner wall of the connecting frame 3. An adjusting mechanism for moving the adjusting rod 31 is provided inside the connecting frame 3. A push plate 21 is fixedly connected to the bottom of the adjusting rod 31, and the push plate 21 is slidably connected to the collection frame 2.

[0026] In this solution, the collection frame 2 can collect and process impurities inside the cleaning frame 5. The adjustment mechanism can move the adjustment rod 31, which in turn moves the push plate 21, thereby pushing the impurities inside the collection frame 2 to the inclined end of the collection frame 2 and collecting them by falling down the inclined surface. This eliminates the need for manual removal of the collection frame 2 and subsequent cleaning of the impurities, resulting in higher work efficiency.

[0027] like Figure 6 and Figure 11As shown: In this solution, the pushing mechanism includes a pushing plate 52 that is slidably connected to the inner wall of the cleaning frame 5. A connecting rod 51 is symmetrically fixedly connected to the top of the pushing plate 52. A fixing block 61 is symmetrically fixedly connected to the inner wall of the fixing frame 4. An electric push rod 62 is fixedly connected to one side of the fixing block 61. An L-shaped sliding seat 6 is fixedly connected to the output end of the electric push rod 62. The L-shaped sliding seat 6 is slidably sleeved on the connecting rod 51.

[0028] In this scheme, the L-shaped sliding seat 6 is moved by the electric push rod 62, and the L-shaped sliding seat 6 drives the push plate 52 to slide through the connecting rod 51, thereby pushing the impurities inside the cleaning frame 5 into the collection frame 2.

[0029] like Figure 4 As shown: In this scheme, a bottom protective frame 41 is fixedly connected to the bottom of the fixed frame 4, and guide wheels 44 for guiding the connecting rope 43 are symmetrically installed on the bottom of the fixed frame 4 and on one side of the bottom protective frame 41.

[0030] In this design, the bottom protective frame 41 provides shielding and protection, and the guide wheel 44 guides the connecting rope 43.

[0031] like Figure 6 and Figure 7 As shown: In this scheme, the inside of the fixing frame 4 is provided with a cable arrangement assembly for arranging the connecting rope 43. The cable arrangement assembly includes a mounting frame 8 symmetrically fixedly connected to the inner wall of the fixing frame 4. An adjusting block 83 is slidably connected to the inner wall of the mounting frame 8, and a guide ring 84 is fixedly connected to the outside of the adjusting block 83. A reciprocating screw 82 is rotatably connected to the inside of the mounting frame 8 through a bearing. The adjusting block 83 is threadedly connected to the reciprocating screw 82. One end of the reciprocating screw 82 extends to the outside of the mounting frame 8. The reciprocating screw 82 and the rotating shaft 45 are connected by a second synchronous belt 81.

[0032] In this scheme, the rotating shaft 45 drives the reciprocating screw 82 to rotate via the second synchronous belt 81, thereby causing the adjusting block 83 to slide along the inner wall of the mounting frame 8. The adjusting block 83 moves via the guide ring 84, thereby performing the winding operation on the connecting rope 43 when it is wound up.

[0033] like Figure 10 As shown: In this scheme, a first motor 48 is fixedly connected to the outer side of the fixed frame 4, the output end of the first motor 48 is fixedly connected to the rotating shaft 45, and a protective frame 42 is fixedly connected to the outside of the fixed frame 4; the adjustment mechanism includes a first lead screw 32 rotatably connected to the inside of the connecting frame 3 through a bearing, the adjusting rod 31 is threadedly connected to the first lead screw 32, and the first lead screw 32 and the rotating shaft 45 are connected by a first synchronous belt 46.

[0034] In this solution, the first motor 48 can be protected by the protective frame 42. The first motor 48 drives the rotating shaft 45 to rotate. The rotating shaft 45 drives the first lead screw 32 to rotate via the first synchronous belt 46. The rotation of the first lead screw 32 drives the adjusting rod 31 to move along the inner wall of the connecting frame 3. The adjusting rod 31 drives the push plate 21 to move, thereby pushing the impurities inside the collection frame 2 to the inclined end of the collection frame 2 and collecting them by falling down the inclined surface.

[0035] like Figure 3 and Figure 4 As shown: In this scheme, the bottom of the fixing frame 4 is symmetrically fixedly connected with an L-shaped fixing seat 7. The interior of the L-shaped fixing seat 7 is rotatably connected with a connecting shaft 72. One end of the connecting shaft 72 extends to the outside of the L-shaped fixing seat 7. Multiple flexible striking rods 71 ​​are fixedly connected in a ring array on the outside of the L-shaped fixing seat 7. A second motor 73 is fixedly connected to the outside of the L-shaped fixing seat 7. The output end of the second motor 73 is fixedly connected to the connecting shaft 72.

[0036] In this scheme, the second motor 73 drives the flexible striking rod 71 to rotate through the connecting shaft 72, thereby striking the top of the push plate 52 through the flexible striking rod 71, so as to shake off some impurities attached to the push plate 52 and drop them into the collection frame 2 for collection.

[0037] Working principle: In use, during the use of water conservancy engineering canals, the filter plate 11 can filter and remove impurities from the water in the canal. In the initial state, the push plate 21 is located on the side close to the inclined surface of the collection frame 2. When the filter plate 11 needs to be cleaned regularly, the first motor 48 is started. The first motor 48 drives the rotating shaft 45 to rotate, and the rotating shaft 45 drives the winding roller 47 to rotate, thereby winding the connecting rope 43. The connecting rope 43 drives the cleaning frame 5 to move upward along the bottom support frame 1, thereby scraping and collecting impurities on the outside of the filter plate 11 through the cleaning frame 5. At the same time, the rotating shaft 45 drives the reciprocating screw 82 to rotate through the second synchronous belt 81, thereby driving the adjusting block 83 to slide along the inner wall of the mounting frame 8. The adjusting block 83 moves through the guide ring 84, thereby performing the cable laying operation when the connecting rope 43 is wound up. At the same time, the rotating shaft 45 drives the first lead screw 32 to rotate through the first synchronous belt 46. The rotation of the first lead screw 32 drives the adjusting rod 31 to slide along the inner wall of the connecting frame 3. The adjusting rod 31 drives the push plate 21 to move away from the inclined end of the collection frame 2. When the cleaning frame 5 rises to the highest point, the inner wall of the cleaning frame 5 is flush with the top of the filter plate 11, and the push plate 21 moves to the end away from the inclined surface of the collection frame 2. During the upward movement of the cleaning frame 5, the connecting rod 51 slides along the L-shaped sliding seat 6. When the cleaning frame 5 reaches its highest point, the electric push rod 62 is activated, which moves the L-shaped sliding seat 6. The L-shaped sliding seat 6 then moves the push plate 52 via the connecting rod 51, thus pushing the impurities inside the cleaning frame 5 into the collection frame 2. The second motor 73 is then activated, which rotates the flexible striking rod 71 via the connecting shaft 72. This causes the flexible striking rod 71 to strike the top of the push plate 52, facilitating the shaking off some impurities attached to the push plate 52 and allowing them to fall into the collection frame 2 for collection. After the material is pushed, the electric push rod 62 is activated to reset the push plate 52, and the first motor 48 is started. The first motor 48 drives the rotating shaft 45 to rotate in the opposite direction, and the rotating shaft 45 drives the take-up roller 47 to rotate in the opposite direction, thereby unloading the connecting rope 43. This causes the cleaning frame 5 to slide down along the bottom support frame 1. At the same time, the rotating shaft 45 drives the first lead screw 32 to rotate through the first synchronous belt 46. The rotation of the first lead screw 32 drives the adjusting rod 31 to move. The adjusting rod 31 drives the push plate 21 to move towards the inclined end of the collection frame 2, thereby pushing the impurities inside the collection frame 2 to the inclined end of the collection frame 2 and collecting them by falling down the inclined surface. There is no need to manually remove the collection frame 2 and clean the impurities again, which improves work efficiency.
