Description

The present invention belongs to the technical field of water conservancy engineering, and in particular to an ecological barrier structure for agricultural non-point source pollution.

Non-point source pollution Dissolved and solid pollutants flow from non-specific locations into rivers, lakes, dams, inlets, etc. through runoff processes under the action of scouring caused by precipitation, causing eutrophication of water bodies and other forms of pollution. In contrast to point source pollution, non-point source pollution is mainly caused by surface soil particles, nutrients such as nitrogen and phosphorus, harmful substances such as pesticides, solid waste such as straw and agricultural films, fecal wastewater from livestock and poultry farming, sewage and garbage from rural life, etc., which enter the aquatic environment through surface runoff, soil erosion, farmland drainage, etc.

Current interception devices generally have a filter net installed in the area that needs to be intercepted, and a biodegradable layer installed on the backwater side of the filter net. However, current interception devices use a single-structure filter net, and since there are generally large amounts of impurities in water bodies, these impurity wastes are likely to accumulate on the surface of the filter net and cause clogging, which will affect the flow of the water body and further affect the treatment of non-point source pollution.

The purpose of the embodiment of the present invention is to provide an ecological interception structure for agricultural non-point source pollution, which aims to solve the problem that the current interception device adopts a single-structure filter net, and since there are generally a large amount of impurities in water bodies, these impurity wastes are easily accumulated on the surface of the filter net and cause clogging, which affects the flow of the water body and further affects the treatment of non-point source pollution.

To achieve the above objective, the present invention provides the following technical solutions:

An ecological barrier construction structure for agricultural non-point source pollution, comprising: a gate body, the gate body being fixedly mounted in a culvert; a filter section being fixedly installed on the gate body; and a biodegradable layer being further installed on the gate body, the biodegradable layer being located on a backwater side of the filter section,
The filtering section includes a plurality of sets of rear filtering plates and pre-filter plates that are alternately arranged, and adjacent sets of rear filtering plates and pre-filter plates are connected by connecting filtering plates, and an upstream surface of the filtering section is provided with a lifting chamber corresponding to the rear filtering plate;
a lifting assembly disposed within the lifting chamber;
The gate body further includes a cleaning assembly, the cleaning assembly corresponds to the pre-filter plate, and the cleaning assembly is used to clean the clogged second filter hole;
A floating block mechanism is further installed in the gate body, and when the filtering section becomes clogged, the water level upstream of the filtering section is raised, the floating block mechanism is used to operate the cleaning assembly, and the cleaning assembly is used to clean the clogged second filtering hole.

Furthermore, the rear filter plate has a plurality of first filter through holes, and the front filter plate has a plurality of second filter holes, and the first and second filter through holes are used to filter the water flow and block impurities and debris in the water flow.

Furthermore, the lifting assembly includes two sets of lifting rollers supported and rotatably mounted in the lifting chamber, a lifting belt wound between the two sets of lifting rollers, a plurality of sets of lifting rods equally spaced on the lifting belt, the lifting rods including a plurality of equally spaced rod bodies, the lifting assembly further includes a lifting motor for rotating the lifting rollers, and in a specific use, the lifting motor is used to rotate the lifting rollers, which operates the lifting belt and drives the lifting rods to pull up the garbage impurities in the lifting chamber.

Furthermore, a collection box is further installed on the gate body, and the collection box has a collection port on one side of the top, and a material stop rod group that cooperates with the lifting rod group is fixedly installed on the collection port. Similarly, the material stop rod group includes a plurality of rod bodies installed at equal intervals, and the rod bodies included in the material stop rod group cross the rod bodies included in the lifting rod group, so that when the rod bodies of the lifting rod group pass through the rod bodies of the material stop rod group, the garbage impurities on the lifting rod group fall onto the material stop rod group and are collected in the collection box.

The ends of the lifting rod group have soft brushes, and the soft brushes on the end of the lifting assembly facing the rear filter plate are in contact with the first filtering through holes, so that when the lifting assembly is operating, the soft brushes on the ends of the lifting rod group can clean the clogged first filtering through holes.

Furthermore, the cleaning assembly includes a support shaft supported by the gate body and rotatably mounted thereon, a cleaning rod is fixedly attached coaxially to the support shaft, and a plurality of cleaning brushes are installed on the cleaning rod, and the cleaning brushes also have soft brushes at their ends, and the soft brushes at the ends of the cleaning brushes are in contact with the second filter holes, and when the cleaning rod rotates, the soft brushes at the ends of the cleaning brushes are used to clean the clogged second filter holes.

The cleaning assembly further includes a support seat, which is fixed to the gate body, and an interlocking chamber is opened in the support seat, the top of the support shaft extends into the interlocking chamber, a driven bevel gear is installed at the top end of the support shaft, and a drive bevel gear that meshes with the driven bevel gear is further rotatably installed in the interlocking chamber, and when the drive bevel gear rotates, the support shaft is rotated by the interlocking caused by the meshing of the driven bevel gear.

Furthermore, the floating block mechanism includes a first floating block, which is supported and fixed to a first lifting rack bar, a second vertical guide rail is opened on the gate body, the first lifting rack bar is supported and slidably installed on the second vertical guide rail, the first lifting rack bar has a rack that can mesh with the drive bevel gear, and when the water level on the upstream side of the filtration section rises to the point where it submerges the first floating block, the first floating block rises and pushes the first lifting rack bar to move it upward, and when the first lifting rack bar moving upward meshes with the drive bevel gear, the drive bevel gear is rotated.

Furthermore, the floating block mechanism further includes a limiting assembly, the limiting assembly including a support baffle, which is located directly above the first lifting rack bar and is used to limit the upward movement of the first floating block when the water level upstream of the filtration section submerges the first floating block, and after the support baffle is removed, the first floating block drives the first lifting rack bar to move upward only when the water level submerges the first floating block.

The support baffle is fixedly attached to a push-pull frame, the push-pull frame is fitted into a guide post, and the guide post is fixedly attached to the surface of one side of the rotating gear. When the rotating gear rotates, the guide post makes a circular motion, pushing the push-pull frame to form a horizontal displacement, and further moving the support baffle away from above the first lifting rack bar.

The floating block mechanism further includes a second floating block, which is supported and fixed to a second lifting rack bar. A first vertical guide rail is further provided on the gate body, and the second lifting rack bar is supported and slidably installed within the first vertical guide rail. The second lifting rack bar has a rack that can mesh with a rotating gear. When the water level on the upstream side of the filtration section rises to the point where it submerges the second floating block, the second floating block rises and pushes the second lifting rack bar to move it upward. When the second lifting rack bar moving upward meshes with the rotating gear, the rotating gear is rotated, and the rotating gear causes the guide post to perform a circular motion, which further pushes the support baffle to cause a displacement, so that the support baffle moves away from above the first lifting rack bar.

Furthermore, the horizontal height at which the second floating block is located is higher than the horizontal height at which the first floating block is located.

Furthermore, a liquid level sensor and a controller are further installed on the top of the gate body, the control signal input terminal of the controller is connected to the liquid level sensor, and the control signal output terminal of the controller is connected to the lifting motor. When the operating cleaning assembly is insufficient in cleaning the clogged second filter hole, the rising water level will contact the liquid level sensor, the liquid level sensor will send a signal to the controller, the controller will control the operation of the lifting motor, and the lifting motor will drive the operation of the lifting assembly, on the one hand, to lift and discharge the impurities and waste in the lifting chamber, and on the other hand, to clean the clogged first filter through hole so that the water flow can pass through the filtration section smoothly.

Compared with the prior art, when the filter section of the ecological barrier construction structure for agricultural non-point source pollution provided by the present invention becomes clogged, on the one hand, the floating block mechanism can be submerged using the water level, and the operation of the floating block mechanism can be used to make the cleaning assembly clean the clogged second filter hole, and on the other hand, the lifting assembly can be used to clean the first filter hole, thereby effectively solving the problem that in a single-structure filter net, these impurities are easily deposited on the surface of the filter net, causing clogging and affecting the flow of the water body.

Here, in the process of using the floating block mechanism provided by the present invention, if the filtration section becomes clogged, the water level upstream of the filtration section will continue to rise, and since the height of the first floating block is lower than that of the second floating block, the support baffle will be located at the top end of the first lifting rack bar, and even if the first floating block is submerged by the water level, it will not move up, but the water level will continue to rise, and when the water level submerges the second floating block, the second floating block will move up, and the rotating gear will rotate until the support baffle leaves the top of the first lifting rack bar, and at this time, since the first floating block is already at a relatively deep position in the water area, the buoyancy of the first floating block is relatively large, and when the support baffle releases the first lifting rack bar, the first floating block will move up, and after the first lifting rack bar engages with the driving bevel gear, the first floating block, which continues to move up, will rotate the driving bevel gear, which will further rotate and drive the cleaning rod, and the cleaning brush on the cleaning rod will be used to clean the clogged second filter hole.

The gate body 200 is further provided with a biodegradable layer 400, which is located on the backwater side of the filtration section 300. After the water flow upstream of the filtration section 300 is filtered by the filtration section 300, the water area from which the impurities have been filtered is further treated by the biodegradable layer 400.

Furthermore, the rear filter plate 301 has a plurality of first filter through holes 3011, and the front filter plate 302 has a plurality of second filter holes 3021. The first filter through holes 3011 and the second filter holes 3021 are used to filter the water flow and block impurities and debris in the water flow.

Furthermore, as shown in FIG. 1 and FIG. 7, in the embodiment of the present invention, a collection box 500 is further installed on the gate body 200, and the collection box 500 has a collection port 501 on one side of the top, and a material stop rod group 502 cooperating with the lifting rod group 606 is fixedly installed in the collection port 501. Similarly, the material stop rod group 502 includes a plurality of rod bodies installed at equal intervals, and the rod bodies included in the material stop rod group 502 cross the rod bodies included in the lifting rod group 606, so that when the rod body of the lifting rod group 606 passes through the rod body of the material stop rod group 502, the garbage impurities on the lifting rod group 606 fall into the material stop rod group 502 and are collected in the collection box 500.

In addition, the ends of the lifting rod group 606 have soft brushes, and the soft brushes at the ends of the lifting assembly 600 facing the rear filter plate 301 are in contact with the first filtering through holes 3011, so that when the lifting assembly 600 is operating, the soft brushes at the ends of the lifting rod group 606 can clean the clogged first filtering through holes 3011.

Furthermore, as shown in FIG. 1, FIG. 8 and FIG. 10, in the embodiment of the present invention, the gate body 200 is further provided with a cleaning assembly, which corresponds to the pre-filter plate 302, and is used to clean the clogged second filter hole 3021.

Specifically, as shown in FIG. 8 and FIG. 10, in an embodiment of the present invention, the cleaning assembly includes a support rotation shaft 704 supported and rotatably mounted on the gate body 200, a cleaning rod 705 is fixedly attached coaxially to the support rotation shaft 704, and a plurality of cleaning brushes 7051 are installed on the cleaning rod 705, and the cleaning brushes 7051 also have soft brushes at their ends, and the soft brushes at the ends of the cleaning brushes 7051 are in contact with the second filter holes 3021, and when the cleaning rod 705 rotates, the soft brushes at the ends of the cleaning brushes 7051 are used to clean the clogged second filter holes 3021.

Continuing to refer to FIG. 1 and FIG. 8, in an embodiment of the present invention, the cleaning assembly includes a support seat 700, the support seat 700 is fixed to the gate body 200, an interlocking chamber 702 is opened in the support seat 700, the top of the support rotation shaft 704 extends into the interlocking chamber 702, a driven bevel gear 703 is installed at the top end of the support rotation shaft 704, and a driving bevel gear 701 meshing with the driven bevel gear 703 is further rotatably installed in the interlocking chamber 702, and when the driving bevel gear 701 rotates, the support rotation shaft 704 is rotated by the meshing of the driven bevel gear 703.

Furthermore, as shown in Figures 1, 2, and 4 to 8, in an embodiment of the present invention, a floating block mechanism is further installed in the gate body 200, and when the filtration section 300 becomes clogged, the water level upstream of the filtration section 300 is raised, the cleaning assembly is operated using the floating block mechanism, and the clogged second filter hole 3021 is cleaned using the cleaning assembly.

Specifically, the floating block mechanism includes a first floating block 201, which is supported and fixed to a first lifting rack bar 2011, a second vertical guide rail 208 is provided on the gate body 200, and the first lifting rack bar 2011 is supported and slidably mounted on the second vertical guide rail 208, and the first lifting rack bar 2011 has a rack that can mesh with the driving bevel gear 701, and when the water level on the upstream side of the filtration section 300 rises to the point where the first floating block 201 is submerged, the first floating block 201 rises and pushes the first lifting rack bar 2011 to move upward, and when the first lifting rack bar 2011 moving upward meshes with the driving bevel gear 701, the driving bevel gear 701 is rotated.

As shown in Figures 2, 5 and 6, in an embodiment of the present invention, the floating block mechanism further includes a limiting assembly, which includes a support baffle 205, which is located directly above the first lifting rack bar 2011 and is used to limit the upward movement of the first floating block 201 when the water level upstream of the filtration section 300 submerges the first floating block 201. After the support baffle 205 is removed, the first floating block 201 drives the first lifting rack bar 2011 to move upward only when the water level submerges the first floating block 201.

Furthermore, in this embodiment of the present invention, the support baffle 205 is fixedly attached to the push-pull frame 204, the push-pull frame 204 is fitted into the guide post 2031, and the guide post 2031 is fixedly attached to one side surface of the rotating gear 203. When the rotating gear 203 rotates, the guide post 2031 makes a circular motion, pushing the push-pull frame 204 to form a horizontal displacement, and further moving the support baffle 205 away from above the first lifting rack bar 2011.

Furthermore, as shown in FIG. 2 and FIG. 6, in this embodiment of the present invention, the gate body 200 further has a horizontal guide rail 207, and a horizontal slider 2041 that cooperates with the horizontal guide rail 207 is fixedly attached to the end of the push-pull frame 204, and the horizontal slider 2041 is supported and slidably installed within the horizontal guide rail 207 so as to maintain a horizontal movement path when the support baffle 205 moves.

Continuing to refer to FIG. 1, FIG. 2 and FIG. 6, in the embodiment of the present invention, the floating block mechanism further includes a second floating block 202, the second floating block 202 is supported and fixedly attached to a second lifting rack bar 2021, the gate body 200 is further provided with a first vertical guide rail 206, the second lifting rack bar 2021 is supported and slidably installed within the first vertical guide rail 206, and the second lifting rack bar 2021 can be engaged with a rotating gear 203. When the water level on the upstream side of the filtration section 300 rises enough to submerge the second floating block 202, the second floating block 202 rises and pushes the second lifting rack bar 2021, moving it upward. When the second lifting rack bar 2021 moving upward meshes with the rotating gear 203, the rotating gear 203 is rotated, and the rotating gear 203 causes the guide post 2031 to move in a circular motion, which in turn pushes the support baffle 205, causing a displacement, so that the support baffle 205 moves away from above the first lifting rack bar 2011.

Preferably, in this embodiment of the present invention, the horizontal height at which the second floating block 202 is located is higher than the horizontal height at which the first floating block 201 is located. As can be understood, when the filtration section 300 is clogged, the water level on the upstream side of the filtration section 300 continues to rise, and the height of the first floating block 201 is lower than the height of the second floating block 202. Therefore, initially, the support baffle 205 is located at the top end of the first lifting rack bar 2011, and even if the first floating block 201 is submerged by the water level, it does not move up. As the water level continues to rise, and the water level submerges the second floating block 202, the second floating block 202 moves up, and then The rotating gear 203 rotates until the support baffle 205 moves away from above the first lifting rack bar 2011. At this time, since the first floating block 201 is already at a relatively deep position in the water area, the buoyancy of the first floating block 201 is relatively large. When the support baffle 205 releases the first lifting rack bar 2011, the first floating block 201 moves upward. After the first lifting rack bar 2011 meshes with the driving bevel gear 701, the first floating block 201, which continues to move upward, rotates the driving bevel gear 701, which further rotates the cleaning rod 705, and uses the cleaning brush 7051 on the cleaning rod 705 to clean the clogged second filter hole 3021.

Furthermore, still referring to FIG. 1, in the embodiment of the present invention, a liquid level sensor 602 and a controller 603 are further installed on the top of the gate body 200, the control signal input terminal of the controller 603 is connected to the liquid level sensor 602, and the control signal output terminal of the controller 603 is connected to the lifting motor 601. When the operating cleaning assembly is not effective enough to clean the clogged second filter hole 3021, the rising water level contacts the liquid level sensor 602, the liquid level sensor 602 sends a signal to the controller 603, the controller 603 controls the operation of the lifting motor 601, and the lifting motor 601 drives the operation of the lifting assembly 600, on the one hand, to lift and discharge impurities and waste in the lifting chamber 304, and on the other hand, to clean the clogged first filter through hole 3011 so that the water flow can pass through the filtration part 300 smoothly.

As can be seen, when the water level drops, the first lifting rack bar 2011 blocks the support baffle 205, so that the support baffle 205 resets directly above the first lifting rack bar 2011 only after the first floating block 201 drops to its original position. Although the embodiments of the present invention are disclosed above, they are not limited to the applications listed in the specification and embodiments, but are fully applicable to various fields suitable for the present invention. Other modifications can be easily implemented by those skilled in the art. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and figures shown and described herein.
