Description

Technical Field

[0001] The invention relates to the technical field of algae cleaning, in particular to a device for cleaning and collecting algae attached to a water channel. Background Art

[0002] Filamentous algae on the walls of water channels are prone to over-reproduction, forming large algae clumps that continue to fall off, causing blockage of water intakes and excessive pH and dissolved oxygen levels in river water. Their decomposition will aggravate the eutrophication of the water body and have a serious impact on the water quality of the channel. Currently, chemical methods are generally used to remove algae, but this brings many side effects, or manual salvage is used to remove them, which is not only time-consuming and labor-intensive, with high processing costs and difficulty in operating at high flow rates, but the fine algae filaments that are not collected will further pollute the water quality, causing secondary pollution.

[0003] There is a thin layer of soil at the connection between the algae and the water channel, so that the roots of the algae can be fixed on the outer wall of the water channel. Existing algae cleaning and collection equipment mostly collects the filamentous algae from the water channel by pulling the filaments of the filamentous algae. However, the filaments of the filamentous algae are extremely fragile, making it difficult to peel the roots of the algae from the inner wall of the water channel, resulting in incomplete cleaning of the algae on the inner wall of the water channel. Summary of the Invention

[0004] The purpose of the present invention is to provide a device for cleaning and collecting algae attached to water channels to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a device for cleaning and collecting algae attached to a water channel, comprising a workbench, a tripod, and a cantilever, wherein a universal head is mounted at the end of the cantilever, a scrubbing head and a suction pipe are mounted on one side of the universal head, a camera is mounted near the end of the cantilever, a pressure roller and a brush roller are disposed inside the scrubbing head, and the suction pipe is mounted above the inside of the scrubbing head;

[0006] A grid and a spiral shaft are provided above the interior of the scrubbing head. The spiral shaft is installed inside the grid. The grid is annular. A separation net is installed on one side of the grid. A pressure roller and a brush roller are installed on the side of the separation net away from the grid.

[0007] The two pressure rollers are arranged, and the two pressure rollers are installed on both sides of the brush roller. A cover plate is arranged on the outside of the brush head; a traction mechanism and a lateral positioning mechanism are installed on the workbench, and the traction mechanism is a traction machine and a collection winch, which are used to provide traction and arrange the anchor cable. Anchor piles are set at high places on both sides of the shore, and anchor cables are extended on the left and right sides of the bow of the water work platform and pulled to the anchor piles. During operation, the equipment is located downstream and the anchor piles are located upstream. The travel direction and working position of the water work platform are adjusted by retracting and releasing the anchor cables; in order to prevent the workbench from being offset by lateral forces during the operation of the cantilever and the brush head, positioning mechanisms are arranged at the four corners of the bottom of the workbench, which are composed of four support arms and provide support force directly to the bottom of the channel. In order to relieve the pressure of the concrete at the bottom of the channel, steel flat feet are provided at the bottom. Before operation, the traction mechanism adjusts the equipment to the appropriate position and then lowers the four support arms to provide stable lateral support after contacting the channel bottom; it travels stably in the high-flow channel, and the travel mode is designed for large-scale water transfer channels with high flow rates. The anchor cables on both sides are used to pull along the water flow to realize the walking and fixing of the workbench in the high-flow water transfer channel to save equipment energy consumption. The horizontal support arms at the four corners below the workbench provide stable support before work. The bilateral synchronous scanning brushing mode in the channel is conducive to the large-span pneumatic cantilever to drive the brushing head, and the two sides of the channel are brushed back and forth synchronously to ensure that the working platform is balanced and there is no risk of rollover, and it is fully cleaned from the channel wall to the channel bottom.

[0008] Furthermore, the pressure roller includes an outer ring, a partition and an inner ring, the partition is installed between the outer ring and the inner ring, the outer ring and the inner ring are both provided with magnetic blocks, the inner part of the outer ring is provided with a spring, and the outer side of the partition is provided with a circular plate; there are two pressure rollers, which are provided on both sides of the brush roller, and the pressure rollers are connected by sprockets and chains. When the scrubbing head is working underwater, the outer wall of the pressure roller contacts the outer wall of the water channel, and the pressure roller moves relative to the inside of the water channel under the drive of the cantilever, and the outer wall of the pressure roller rolls on the outer wall of the water channel. The pressure roller is provided with several outer Ring, partition and inner ring, wherein the inner ring is connected to the sprocket, and magnetic blocks are set inside the inner ring and the outer ring. When either the outer ring or the inner ring rotates, the other inner ring or the outer ring rotates driven by the magnetic block. The partition is installed between the outer ring and the inner ring. The inner diameter of the outer ring is larger than the outer diameter of the inner ring. The outer surface size of the partition matches the gap size between the outer ring and the inner ring; the spring is arranged on both sides of the outer ring, and there is an annular groove between the two adjacent outer rings. The circular plate is installed above the inner part of the annular groove. At the same time, the outer side of the circular plate adopts a chamfering process, and the outer wall cross-section of the circular plate is semicircular.

[0009] Furthermore, a thread groove is provided on the outer wall of the outer ring, a triangular groove is provided inside the outer ring, the reed is V-shaped, the end of the reed is triangular, and the upper surface of the circular plate coincides with the upper end surface of the outer ring; a thin layer of soil exists at the connection between the algae and the canal to facilitate the attachment of the algae to the outer wall of the canal, and when the outer ring rolls on the outer wall of the canal, the outer wall of the outer ring meshes with the soil, and when the outer ring in the rotating state comes into contact with the soil layer, the thread groove is provided on the outer wall of the outer ring, so that the outer ring is in the soil. The longitudinal force is provided on the layer to facilitate the separation of the soil layer from the outer wall of the canal; there is an annular groove between the two adjacent outer rings, and the outer ring extends into the soil layer under the action of the canal pressure. Since springs are installed on both sides of the outer ring, when the spring is located above the inner part of the outer ring, the upper side wall of the outer ring fits with the upper side wall of the circular plate, so that the spring is accommodated in the triangular groove inside the outer ring under the restriction of the circular plate. When the triangular groove where the spring is located passes over the circular plate, the angle formed by the inner wall of the triangular groove is smaller than the natural expansion angle of the spring, thereby The spring moves toward the outside of the triangular groove under the action of its own elastic force. Since the upper surface of the circular plate coincides with the upper end surface of the outer ring, that is, when the triangular groove where the spring is located passes over the circular plate, the extended spring is located below the outer ring, that is, the area where the outer ring contacts the soil layer. The spring penetrates into the soil layer under the action of its own elastic force. Since the outer wall of the outer ring is provided with a threaded groove, the soil layer near the annular groove is peeled off from the soil layer inside the annular groove. The soil layer engaged in the annular groove is temporarily stored under the action of the spring. In the annular groove; when the reed returns from the lower area of ​​the outer ring to the upper area of ​​the outer ring, since the outer side of the circular plate adopts a chamfering process and the end of the reed is triangular, the chamfered area of ​​the circular plate contacts the triangular area on the reed. Under the restriction of the circular plate, the reed is again received into the triangular groove. At the same time, the upper surface of the circular plate coincides with the upper end surface of the outer ring, so that the depth of the upper area of ​​the annular groove is smaller than the depth of the lower area of ​​the annular groove, that is, the soil layer peeled off in the annular groove is separated from the annular groove under the action of the circular plate.

[0010] Furthermore, the separation net is installed inside the cover plate, the separation net is annular, the separation net is arranged on both sides below the grid, a number of collecting teeth are arranged around the outside of the separation net, and a fan blade is installed inside the grid; after the algae on the inner wall of the water channel are collected by the pressure roller and the brush roller, the collected algae are separated from the pressure roller and the brush roller under the action of water flow and centrifugal force, one end of the separation net is connected to the water pump, and the water flow inside the cover plate is extracted during the operation of the water pump, and the outside of the cover plate is connected to a water flow pipe, and the water flow pipe The channel is connected to the separation net. When the water pump is working, water flows through the separation net. When the water flows through the surface of the fan blades, the water flows under the action of the fan blades, causing the separation net to rotate. There are two separation nets. The fan blades inside the two separation nets are in opposite directions, causing the two separation nets to rotate relative to each other. The outer wall of the separation net is provided with collecting teeth. Under the action of the water flow and the rotating collecting teeth, the algae in the cover plate are collected by the collecting teeth. The water flows through the separation net and enters the water flow pipe under the action of the water pump.

[0011] Furthermore, comb teeth are installed at the lower end of the grid, and the ends of the comb teeth are in contact with the outer wall of the separation net. The inner diameter of the grid away from the separation net is smaller than the inner diameter of the side close to the separation net; the outer walls of the comb teeth are in contact with the outer wall of the separation net, and the separation net rotates relative to the grid under the action of water flow, and the algae collected by the collecting teeth are confined between the comb teeth. Since a spiral shaft is installed on the inner wall of the comb teeth, a driving motor is installed on the upper end of the spiral shaft, and the driving motor drives the spiral shaft to rotate, and comes into contact with the algae collected by the comb teeth, and transfers the algae to the grid. Since the inner diameter of the grid away from the separation net is smaller than the inner diameter of the side close to the separation net, the output diameter of the algae is smaller than the input diameter of the algae, forcing the algae to squeeze each other inside the grid, and the residual water in the algae leaves through the through holes on the surface of the grid. The output end of the grid is connected to an algae tube, and the end of the algae tube is connected to an algae storage box. The algae collected by the grid is finally moved to the algae storage box.

The cantilever is divided into two sections, the main arm and the small arm. It is made of high-strength manganese steel to provide better torsional rigidity. The longitudinal section is a trapezoidal structure, and the outside of the small arm is covered with a streamlined stainless steel shell. Both the main arm and the small arm are driven by high-pressure cylinders. The operation is gentle, which helps to reduce the pressure applied to the concrete surface. A movable lifting triangular gantry is installed at the bow, which can be flattened as needed when passing through the bridge hole. During operation, the bagged algae residue can be hoisted onto the auxiliary working platform and transported to the shore.

[0013] Furthermore, one end of the brush roller is movably connected to the cover plate, an air motor is provided at one end of the brush roller, a rectangular spiral groove is provided on the outside of the brush roller, and bristles are installed on the outside of the brush roller.

[0014] Furthermore, an isolation skirt is installed on one side of the cover plate, and the cantilever and the scrubbing head are installed with a cross-member, which is telescopic; the pressure roller and the brush roller are made of special polyester rubber, and the brush roller is a special internal aluminum cylinder and an external soft brush structure. An underwater camera is provided near the end of the cantilever to observe the cleaning working surface in real time to ensure that the attached filamentous algae are completely removed. The scrubbing head is fixed to the end of the cantilever through a retractable cross universal joint, so that the scrubbing head can flexibly change the scrubbing posture according to the unevenness of the contact channel surface and the direction of travel during the movement of the cantilever. The rotational linear speed of the pressure roller is less than that of the brush roller, and the rotational speed of the brush roller is relatively large to facilitate scrubbing of the bristle algae on the concrete surface.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This device for cleaning and collecting algae attached to water channels uses a pressure roller to separate the soil layer into multiple separate parts as it moves over the soil layer, thereby isolating the connections between the algae roots. The subsequent brush roller collects filamentous algae, preventing the algae roots from adhering to the outer wall of the channel, resulting in incomplete algae cleaning. The pressure roller reduces the adhesion strength of the algae roots on the outer wall of the channel, thereby reducing the time required for the brush roller to scrub the outer wall of the channel.

[0017] 2. The water channel is attached with an algae cleaning and collection device. Through the arrangement of a grid and a spiral shaft, the grid and the spiral shaft cooperate with each other to squeeze the algae inside the grid, squeezing away excess water on the algae surface, thereby increasing the storage capacity of the algae box. At the same time, comb teeth are installed under the grid to clean the surface of the separation net and recover the algae collected by the separation net;

[0018] 3. The water channel is attached with algae cleaning and collection equipment. Through the setting of the separation net, a water pump is connected to one side of the separation net. The water pump forms a water flow inside the separation net by extraction. The water flow cooperates with the fan blades and the collecting teeth to collect the algae after brushing. At the same time, the rotating collecting teeth cooperate with the comb teeth to achieve a self-cleaning effect, so that the brush can be used for a long time. BRIEF DESCRIPTION OF THE DRAWINGS

When the pressing roller 6 moves on the soil layer, the soil layer is separated into multiple separate parts to cut off the connection between the algae roots. In the subsequent process of collecting filamentous algae, the brush roller 7 prevents the algae roots from adhering to the outer wall of the canal, resulting in the phenomenon of incomplete algae cleaning. By moving in a pressing manner, the adhesion strength of the algae roots on the outer wall of the canal is reduced, thereby reducing the time required for the brush roller 7 to brush the outer wall of the canal.

A water pump is connected to one side of the separation net 11. The water pump forms a water flow inside the separation net 11 by extraction. The water flow cooperates with the fan blade 1102 and the collecting teeth 1101 to collect the algae after brushing. At the same time, the rotating collecting teeth 1101 cooperate with the comb teeth 801 to achieve a self-cleaning effect, so that the scrubbing head 4 can work for a long time.

At the same time, comb teeth 801 are installed under the grid 8 to clean the surface of the separation net 11 and recover the algae collected by the separation net 11.

[0037] Working principle of the present invention:

[0038] The steel double-floating work platform 1 is made of CCSB-grade ship steel plates and is equipped with an air-cooled ultra-quiet diesel generator set to provide power for all equipment. A universal electric thruster is used to provide propulsion for adjusting the equipment's operating posture. A traction mechanism and a lateral positioning mechanism are installed on the work platform 1. The traction mechanism is a tractor and a retracting winch, which are used to provide traction and organize the anchor cables. Anchor piles are set at high places on both sides of the shore. Anchor cables are extended from the left and right sides of the bow of the water work platform 1 and pulled to the anchor piles. During operation, the equipment is located downstream and the anchor piles are located upstream. The travel direction and working position of the water work platform are adjusted by retracting and releasing the anchor cables. The travel mode is designed for large-scale water transfer channels with high flow rates. Through the traction mechanism and lateral positioning mechanism on the work platform 1, the anchor cables on both sides are used to pull along the water flow, and the work platform 1 can move stably in the high-flow channel, so that the work platform 1 can move and be fixed in the high-flow channel to save equipment energy consumption.

[0039] Positioning mechanisms are set at the four corners of the bottom of the workbench 1. In order to prevent the workbench 1 from being offset by lateral forces during the operation of the cantilever 3 and the scrubbing head 4, it is composed of four support arms, which provide support force directly to the bottom of the channel. In order to relieve the pressure of the concrete at the bottom of the channel, a steel flat foot is provided at the bottom. Before operation, the equipment is adjusted to the appropriate position by the traction mechanism and the four support arms are lowered to provide stable lateral support after contacting the bottom of the channel. The lateral support arms at the four corners below the workbench 1 provide stable support before operation. The bilateral synchronous scanning scrubbing mode in the channel is conducive to the large-span pneumatic cantilever 3 driving the scrubbing head 4 to scrub back and forth synchronously on both sides of the channel, ensuring that the work platform is balanced in force without the risk of overturning, and comprehensively cleaning from the channel wall to the bottom;

[0040] A pyramid-shaped mobile platform base is set on the platform for installing a large-span pneumatic cantilever 3. The generator, air compressor, etc. are installed on the mobile platform. When crossing the bridge, they can be disassembled and hoisted from the bottom working platform. The cantilever 3 is divided into two sections, the big arm and the small arm. It is made of high-strength manganese steel to provide better torsional rigidity. The longitudinal section is a trapezoidal structure. The outside of the small arm is covered with a streamlined stainless steel shell. Both the big arm and the small arm are driven by high-pressure cylinders. The operation is gentle, which is conducive to reducing the pressure applied to the concrete surface. A movable lifting triangular gantry is set at the bow, which can be leveled as needed when crossing the bridge hole. During operation, the bagged algae residue can be hoisted onto the auxiliary working platform and transported to the shore.

[0041] An underwater camera is provided near the end of the cantilever 3 to observe the cleaning work surface in real time and ensure that the attached filamentous algae are completely removed. The scrubbing head 4 is fixed to the end of the cantilever 3 via a retractable cross universal joint, so that the scrubbing head can flexibly change its scrubbing posture according to the unevenness of the contact channel surface and the direction of travel during the movement of the cantilever 3. The pressure roller 6 and the brush roller 7 are made of a special polyester rubber material. The brush roller 7 has a special internal aluminum cylinder and an external soft brush structure. The rotational linear speed of the pressure roller 6 is lower than that of the brush roller 7. The brush roller 7 has a higher rotational speed to facilitate scrubbing of the bristle algae on the concrete surface.

[0042] Two pressure rollers 6 and a brush roller 7 are provided inside the scrubbing head 4. The two pressure rollers 6 are provided on both sides of the brush roller 7. The pressure rollers 6 are connected by sprockets and chains. When the scrubbing head 4 is working underwater, the outer wall of the pressure roller 6 comes into contact with the outer wall of the water channel. The pressure roller 6 moves relative to the inside of the water channel under the drive of the cantilever 3. The outer wall of the pressure roller 6 rolls on the outer wall of the water channel. The reed 605 is provided on both sides of the outer ring 601. At the same time, there is an annular groove between the two adjacent outer rings 601. The circular plate 606 is installed above the inner part of the annular groove. At the same time, the outer side of the circular plate 606 adopts a chamfering process. The circular plate 606 The outer wall cross-section is semicircular, and the pressure roller 6 is provided with a plurality of outer rings 601, partitions 602 and inner rings 603. The inner ring 603 is connected to the sprocket. The inner ring 603 and the outer ring 601 are both provided with magnetic blocks 604. When either the outer ring 601 or the inner ring 603 rotates, the other inner ring 603 or the outer ring 601 rotates driven by the magnetic blocks 604. The partition 602 is installed between the outer ring 601 and the inner ring 603. The inner diameter of the outer ring 601 is larger than the outer diameter of the inner ring 603. The outer surface size of the partition 602 matches the gap size between the outer ring 601 and the inner ring 603.

[0043] A thin layer of soil exists at the junction of the algae and the canal, facilitating the algae's attachment to the outer wall of the canal. As the outer ring 601 rolls on the outer wall of the canal, the outer wall of the outer ring 601 meshes with the soil. During the period when the rotating outer ring 601 comes into contact with the soil, the outer wall of the outer ring 601, provided with a threaded groove, exerts a longitudinal force on the soil, facilitating the separation of the soil from the outer wall of the canal.

[0044] There is an annular groove between two adjacent outer rings 601. The outer ring 601 extends into the soil layer under the pressure of the cantilever 3. Since springs 605 are installed on both sides of the outer ring 601, when the springs 605 are located above the inner part of the outer ring 601, the upper side wall of the outer ring 601 fits with the upper side wall of the circular plate 606, so that the springs 605 are received in the triangular groove inside the outer ring 601 under the restriction of the circular plate 606. When the triangular groove where the springs 605 are located passes over the circular plate 606, the angle formed by the inner wall of the triangular groove is smaller than the natural expansion angle of the springs 605, and then the springs 605 are under the elastic force of themselves. Under the action of the circular plate 606, it moves toward the outside of the triangular groove. Since the upper surface of the circular plate 606 coincides with the upper end surface of the outer ring 601, that is, when the triangular groove where the spring leaf 605 is located passes over the circular plate 606, the extended spring leaf 605 is located below the outer ring 601, that is, the area where the outer ring 601 contacts the soil layer. Under the action of its own elastic force, the spring leaf 605 penetrates into the soil layer. Since the outer wall of the outer ring 601 is provided with a threaded groove, the soil layer near the annular groove and the soil layer inside the annular groove are peeled off. Under the action of the spring leaf 605, the soil layer engaged in the annular groove is temporarily stored in the annular groove.

[0045] When the reed 605 returns from the lower area of ​​the outer ring 601 to the upper area of ​​the outer ring 601, since the outer side of the circular plate 606 is chamfered and the end of the reed 605 is triangular, the chamfered area of ​​the circular plate 606 contacts the triangular area on the reed 605. Under the restriction of the circular plate 606, the reed 605 is again received into the triangular groove. At the same time, the upper surface of the circular plate 606 coincides with the upper end surface of the outer ring 601, so that the depth of the upper area of ​​the annular groove is less than the depth of the lower area of ​​the annular groove. That is, the soil layer peeled off in the annular groove is separated from the annular groove under the action of the circular plate 606.

[0046] After the algae on the inner wall of the canal are collected by the pressing roller 6 and the brush roller 7, the collected algae are separated from the pressing roller 6 and the brush roller 7 under the action of water flow and centrifugal force. One end of the separation net 11 is connected to the water pump. During the operation of the water pump, the water flow inside the cover plate 12 is extracted. The outer side of the cover plate 12 is connected to a water flow pipe, which is connected to the separation net 11. During the operation of the water pump, water flows through the separation net 11. When the water flows through the surface of the fan blade 1102, the water flows on the fan blade 110 2, the separation net 11 rotates. There are two separation nets 11, and the fan blades 1102 inside the two separation nets 11 face in opposite directions, so that the two separation nets 11 rotate relative to each other. The outer wall of the separation net 11 is provided with collecting teeth 1101. Under the action of the water flow and the rotating collecting teeth 1101, the algae in the cover plate 12 are collected by the collecting teeth 1101. The water flows through the separation net 11 and enters the water flow pipe under the action of the water pump.

[0047] The outer wall of the comb teeth 801 fits into the outer wall of the separation net 11, and the separation net 11 rotates relative to the grid 8 under the action of water flow. The algae collected by the collecting teeth 1101 are confined between the comb teeth 801. Since the inner wall of the comb teeth 801 is installed with a spiral shaft 9, the upper end of the spiral shaft 9 is installed with a driving motor. The driving motor drives the spiral shaft 9 to rotate, and contacts the algae collected by the comb teeth 801, and transfers the algae to the grid 8. Since the inner diameter of the grid 8 away from the separation net 11 is smaller than the inner diameter of the side close to the separation net 11, the output diameter of the algae is smaller than the input diameter of the algae, forcing the algae to squeeze each other inside the grid 8, and the residual water in the algae leaves through the through holes on the surface of the grid 8. The output end of the grid 8 is connected to the algae tube, and the end of the algae tube is connected to the algae storage box. The algae collected by the grid 8 is finally moved to the algae storage box.
