Description

Technical Field

[0001] The present application relates to the technical field of underwater surface floating mud cleaning equipment, and in particular to a towed underwater surface floating mud cleaning device. Background Art

[0002] The purpose of water environment management is to protect and improve the water environment and ensure the sustainable use of water resources. The surface floating mud is active and poses a great threat to water quality. This is because the floating mud on the bottom of the water has migration mobility and is rich in fine foam of incompletely decomposed animal and plant remains and excrement of aquatic organisms. After the algae die, they sink to the bottom of the water to decompose organic matter, and the algae spores hibernate in the bottom floating mud. These are all reasons that affect water quality. Therefore, when managing the water environment, it is necessary to clean the floating mud on the bottom of the water.

[0003] However, when the existing equipment is used to clean the floating mud on the surface of the bottom of the water, it only sucks the floating mud on the surface of the bottom of the water. During the suction operation, the turbulence formed at the bottom of the water due to the operation and movement of the equipment will cause part of the floating mud on the surface to be suspended in the water near the bottom of the water in the form of suspended matter. These suspended matter are inconvenient to be cleaned, resulting in incomplete cleaning of the floating mud on the surface of the bottom of the water, affecting the treatment effect of the water environment. If suction is still used for cleaning, a large amount of water will be sucked together with the suspended matter, resulting in low suction efficiency and high cost. Summary of the invention

[0004] The present application proposes a towed underwater surface floating mud removing device, which has the advantages of being able to clean the underwater surface floating mud and, at the same time, being able to clean the surface floating mud suspended in the water in the form of suspended matter at low cost and high efficiency, and is used to solve the problem that when existing equipment cleans the underwater surface floating mud by suction, the suspended matter at the bottom of the water cannot be cleaned, resulting in incomplete cleaning of the underwater surface floating mud.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: a towed underwater surface floating mud removing device, comprising an integrally formed bottom plate and a forward inclined plate, a sewage pumping bin is provided at the top of the connection between the bottom plate and the forward inclined plate, a first through groove connected to the sewage pumping bin is provided on the forward inclined plate, a hydraulic sewage pump is provided on one side of the sewage pumping bin, a water outlet of the hydraulic sewage pump is connected to a sewage pipe, a sewage collecting bin is provided above the sewage pumping bin, a filter is provided on the side of the sewage collecting bin away from the forward inclined plate, a second through groove connected to the sewage collecting bin is provided on the forward inclined plate, through holes for connecting the towing mechanism are respectively provided at both ends of the forward inclined plate away from the bottom plate, a U-shaped fixing for connecting the pulling mechanism is fixedly installed on the top of the bottom plate, and a sealing plate is provided between the sewage pumping bin and the sewage collecting bin.

[0006] The ship on the water surface pulls the forward tilting plate and the bottom plate to move on the bottom of the water through the towing mechanism, and the hydraulic sewage pump sucks the floating mud on the bottom of the water to the ship. At the same time, the filter screen intercepts the suspended matter in the surface floating mud in the water in the sewage collecting bin. The bottom plate and the forward tilting plate are flipped by the towing mechanism to make the forward tilting plate stick to the bottom of the water, and the sealing plate is opened to connect the sewage suction bin and the sewage collecting bin. The hydraulic sewage pump pumps the suspended surface floating mud intercepted in the sewage collecting bin to the ship, so that the suspended matter in the surface floating mud that has not been sucked into the water can also be effectively cleaned, thereby making the cleaning of the floating mud on the bottom of the water more thorough, and avoiding the problem of missing the cleaning of dormant algae sources in the surface floating mud.

[0007] Furthermore, the towing mechanism and the pulling mechanism are respectively configured as chains or cables, through which the ship on the water surface is connected to the first through groove on the forward tilting plate and the U-shaped fixing part on the bottom plate, respectively. By moving the ship on the water surface, the forward tilting plate and the bottom plate can be pulled to move together. When it is necessary to clean the floating mud suspended on the bottom surface in the sewage collecting bin, the bottom plate can be flipped by pulling the chain or cable connected to the U-shaped fixing part, and the forward tilting plate is attached to the bottom of the water. The first through groove and the second through groove are blocked by the mud layer on the bottom of the water, and the hydraulic sewage pump is driven to generate negative pressure suction in the sewage pumping bin, so that water can enter the sewage pumping bin more easily than mud, thereby using water to drive the surface floating mud suspended in the sewage collecting bin to be sucked away together, and by centrally cleaning the floating mud suspended on the bottom surface, the cleaning effect of the floating mud on the bottom surface is good, the efficiency is high, and the cost is low.

[0008] Furthermore, an L-shaped plate is provided on the top of the connection of the forward inclined plate, one side of the L-shaped plate is fixedly connected to the top of the bottom plate, and the other side of the L-shaped plate is fixedly connected to one side of the forward inclined plate. The sewage pumping bin is the inner cavity of the L-shaped plate. The setting of the L-shaped plate facilitates the formation of a sewage pumping bin at the connection of the bottom plate and the forward inclined plate, and facilitates the fixed setting of a rectangular plate on the L-shaped plate, so that a sewage collecting bin for collecting floating mud suspended matter on the surface of the bottom water is provided above the sewage pumping bin, so as to centrally clean the floating mud suspended matter on the surface of the bottom water.

[0009] Furthermore, a crushing device is provided in the sewage pumping bin on one side of the first through groove, and baffles are provided at both ends of the sewage pumping bin respectively, and the two baffles are respectively arranged at the two ends of the crushing device, and a submersible hydraulic pump for driving the crushing device to rotate is fixedly installed on the outer side of one of the baffles. The crushing device consists of a rotating shaft and a plurality of rolling blades on the rotating shaft, which is convenient for crushing solid matter in the water bottom and avoiding the problem of blockage of the sewage pumping and discharge pipe caused by large volume of solid pollutants.

[0010] Furthermore, a slot connecting the sewage extraction bin and the sewage collection bin is opened on the L-shaped plate, and supporting plates close to the top of the L-shaped plate are fixedly installed on the inner sides of the two baffles, and the two ends of the partition plate are movably connected to the two supporting plates, and a linkage block is fixedly installed on the side of the partition plate away from the forward tilting plate, and a first hydraulic cylinder is fixedly installed on the side of the L-shaped plate, and the piston shaft of the first hydraulic cylinder is fixedly connected to the linkage block. The supporting plates and the top of the L-shaped plate are used to limit the two ends of the partition plate to ensure that the partition plate can move stably, thereby achieving the effect of opening the slot and sealing the slot.

[0011] Furthermore, a rectangular plate parallel to the tilting plate is fixedly provided on the top of the L-shaped plate, a filter is installed on the rectangular plate, a positioning plate is fixedly installed on the top of the rectangular plate, and the sewage collecting bin is surrounded by the rectangular plate, the positioning plate, the tilting plate and the top of the L-shaped plate. When the ship pulls the tilting plate and the floor to move, the filter is used to intercept suspended matter in the floating mud on the bottom surface of the water in the sewage collecting bin for centralized cleaning, thereby achieving the effect of saving costs and improving efficiency.

[0012] Furthermore, side cover plates are fixedly installed at both ends of the L-shaped plate, and the side cover plates form a blockage at both ends of the sewage extraction bin and the sewage collection bin.

[0013] Furthermore, a limiting plate away from the tilting plate is fixedly installed on the top of the L-shaped plate, and the rectangular plate is arranged between the limiting plate and the positioning plate. The setting of the limiting plate is convenient for fixing the rectangular plate in conjunction with the positioning plate to ensure that the rectangular plate and the tilting plate are arranged in parallel.

[0014] Furthermore, two first positioning shafts away from one side of the forward tilting plate are fixedly installed on the top of the bottom plate, and the two first positioning shafts are close to the two ends of the bottom plate respectively. First counterweight blocks are movably mounted on the two first positioning shafts, and the first counterweight blocks are fixed by pins passing through the first positioning shafts. According to the cleaning depth of the floating mud on the bottom surface, the first counterweight blocks of corresponding weights are set, so that the ship pulls the forward tilting plate and the bottom plate to move, and the floating mud on the bottom surface can be stably sucked.

[0015] Furthermore, second positioning shafts are fixedly installed at both ends of the forward inclined plate away from the bottom plate, and a second counterweight is movably mounted on the second positioning shaft, and the second counterweight is fixed by a pin penetrating the second positioning shaft. When the suspended matter of the floating mud on the bottom surface collected in the sewage collecting bin is sucked out, the second counterweight is set to make the forward inclined plate stably stick to the bottom silt layer, and effectively block the two through grooves on the forward inclined plate, so that water can enter the sewage extraction bin through the filter screen and the sewage collecting bin, and drive the suspended matter of the floating mud on the bottom surface collected in the sewage collecting bin to be discharged together.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. The present application provides a towed underwater surface floating mud removal device, which uses a sewage pumping bin and a sewage collecting bin arranged between a bottom plate and a forward inclined plate. The ship on the water surface pulls the forward inclined plate and the bottom plate to move on the bottom of the water through a towing mechanism, and a hydraulic sewage pump sucks the underwater surface floating mud onto the ship, thereby quickly removing the surface floating mud that is harmful to the water quality, and at the same time removing the dormant algae species in the surface floating mud, creating excellent conditions for maintaining water quality, and reducing the operating cost by only removing the pollution sources in the surface mud that is harmful to the water quality, and is not easy to cause the pollution sources to spread, so that the water environment management effect is better.

[0018] 2. The ship uses the towing mechanism to pull the tilting plate and the bottom plate to move on the bottom of the water. While cleaning the surface floating mud that is harmful to the water quality, the filter screen intercepts the surface floating mud suspended matter in the water in the sewage collecting bin. The bottom plate and the tilting plate are pulled over by the towing mechanism to make the tilting plate stick to the bottom of the water, and the sealing plate is opened to connect the sewage pumping bin and the sewage collecting bin. The hydraulic sewage pump pumps the surface floating mud suspended matter intercepted in the sewage collecting bin to the ship, so that the surface floating mud suspended matter that has not been sucked into the water can also be effectively cleaned, thereby making the cleaning of the bottom surface floating mud more thorough, avoiding the omission of cleaning dormant algae sources in the surface floating mud, and compared with the existing equipment that directly sucks the surface floating mud suspended matter in the water, it avoids a large amount of water suction work, so that the cleaning efficiency of the bottom surface floating mud suspended matter is higher and the cost is lower.

[0019] 3. The ship uses the towing mechanism to pull the forward tilting plate and the bottom plate to move on the bottom of the water. While cleaning the surface floating mud that is harmful to the water quality, the filter screen intercepts the surface floating mud suspended matter in the water in the sewage collection bin. When cleaning the bottom surface floating mud suspended matter in the sewage collection bin, the filter screen is backwashed with water to avoid the problem of filter screen blockage, so that when the bottom surface floating mud is subsequently sucked out, the bottom surface floating mud suspended matter can continue to be efficiently filtered and intercepted. It is suitable for continuous cleaning of the bottom surface floating mud in large waters. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Embodiment 1, as Figure 1-Figure 3A towed underwater surface floating mud removal device comprises an integrally formed bottom plate 1 and a forward inclined plate 2. An L-shaped plate 3 is arranged on the top of the connection between the bottom plate 1 and the forward inclined plate 2. One side of the L-shaped plate 3 is fixedly connected to the top of the bottom plate 1, and the other side of the L-shaped plate 3 is fixedly connected to one side of the forward inclined plate 2. The inner cavity of the L-shaped plate 3 is a sewage suction bin located at the connection between the bottom plate 1 and the forward inclined plate 2. Please refer to Figure 4-Figure 5 The front tilting plate 2 is provided with a first through slot 201 near the bottom plate 1, and a crushing device 4 is provided in the sewage pumping chamber on one side of the first through slot 201. Through holes 202 are respectively provided at both ends of the front tilting plate 2 away from the bottom plate 1. Through the through holes 202, a towing mechanism is conveniently connected between the front tilting plate 2 and the ship. The towing mechanism can be set as a chain, a cable or other structure (the ship and the towing mechanism are both existing public technologies, which are not the innovation of this application, and are not drawn in the figure, nor will they be described in detail), so that when the ship moves on the water surface, the front tilting plate 2 and the bottom plate 1 can be pulled to move on the bottom of the water. Please refer to Figure 1-Figure 4 A hydraulic sewage pump 5 is fixedly mounted on the L-shaped plate 3, and a water outlet of the hydraulic sewage pump 5 is connected to a sewage pipe 6, and one end of the sewage pipe 6 away from the hydraulic sewage pump 5 extends to the ship.

[0034] When the ship moves on the water surface and pulls the forward tilting plate 2 and the bottom plate 1 to move on the bottom of the water, the hydraulic sewage pump 5 is used to suck the floating mud on the bottom of the water onto the ship, so as to quickly remove the surface floating mud that is harmful to the water quality, and at the same time remove the dormant algae species in the surface floating mud, so as to create excellent conditions for maintaining water quality. By only removing the pollution sources in the surface mud that are harmful to the water quality, the operating cost is reduced, and it is not easy to cause the pollution sources to spread, so that the water environment management effect is better. Compared with the submersible pump, the setting of the hydraulic sewage pump 5 avoids the safety hazard of needing to send power to the underwater.

[0035] A limiting plate 7 away from one side of the forward tilting plate 2 is fixedly installed on the top of the L-shaped plate 3. A positioning plate 8 away from one side of the bottom plate 1 is fixedly installed on the forward tilting plate 2, and the positioning plate 8 is vertically arranged with the forward tilting plate 2. A rectangular plate 9 is fixedly installed between the positioning plate 8 and the limiting plate 7. The rectangular plate 9 is arranged parallel to the forward tilting plate 2. A filter screen 10 is arranged on the rectangular plate 9. The top of the L-shaped plate 3 and the rectangular plate 9, the positioning plate 8, and the forward tilting plate 2 form a sewage collecting bin located above the sewage pumping bin. Please participate. Figure 3-Figure 5 The front tilting plate 2 is provided with a plurality of second through slots 203 arranged at equal intervals, the number of the second through slots 203 is not less than two, and the second through slots 203 are connected to the dirt collecting bin, see Figure 1-Figure 2 The two ends of the L-shaped plate 3 are respectively fixedly mounted with side cover plates 11, and the side cover plates 11 form a blockage at both ends of the sewage extraction bin and the sewage collection bin.

[0036] The ship moves on the water surface, pulling the forward tilting plate 2 and the bottom plate 1 to move on the bottom of the water, and when the floating mud on the bottom of the water is sucked and removed, due to the disturbance of the equipment operation, some of the floating mud on the bottom of the water surface will not be sucked up, and thus will be suspended in the water near the bottom of the water. By utilizing the movement of the forward tilting plate 2 and the bottom plate 1 on the bottom of the water, the water will flow through the second through groove 203 and the rectangular plate 9, and the rectangular plate 9 will be filtered and intercepted, so that the surface floating mud suspended in the water that is not sucked up is intercepted in the sewage collecting bin, so as to facilitate the subsequent centralized cleaning of the surface floating mud suspended in the sewage collecting bin.

[0037] A U-shaped fixing part 12 is fixedly installed on the top of the bottom plate 1, which is away from one side of the front tilting plate 2. The U-shaped fixing part 12 is arranged in the middle of the bottom plate 1. The U-shaped fixing part 12 is connected to the ship through a towing mechanism. The towing mechanism can be a chain or a cable. Two first positioning shafts 13 are fixedly installed on the top of the bottom plate 1, which are away from one side of the front tilting plate 2. The two first positioning shafts 13 are respectively close to the two ends of the bottom plate 1. The two first positioning shafts 13 are movably sleeved with first counterweights 14, and the first counterweights 14 are inserted through the first positioning shafts 13. The first counterweight 14 is fixed by a pin, and the arrangement of the first counterweight 14 makes it possible for the bottom of the bottom plate 1 to remain close to the bottom of the water when the front tilting plate 2 and the bottom plate 1 move under the towing of the ship, and at the same time makes the bottom plate 1 sink to the floating mud on the surface of the bottom of the water, so that the floating mud on the surface of the bottom of the water can be smoothly sucked. The two ends of the front tilting plate 2 away from the bottom plate 1 are respectively fixedly installed with second positioning shafts 15, and the second positioning shafts 15 are movably sleeved with a second counterweight 16, and the second counterweight 16 is fixed by a pin passing through the second positioning shaft 15.

[0038] See also Figure 3 , Figure 4 and Figure 6, baffles 17 are respectively provided at both ends of the sewage pumping bin, and the two baffles 17 are respectively arranged at the two ends of the crushing device 4, and a submersible hydraulic pump for driving the crushing device 4 to rotate is fixedly installed on the outer side of one of the baffles 17, and a slot 301 connecting the sewage pumping bin and the sewage collecting bin is opened on the L-shaped plate 3, and a supporting plate 18 close to the top of the L-shaped plate 3 is respectively fixedly installed on the inner sides of the two baffles 17, and a partition plate 19 is movably provided below the slot 301, and the partition plate 19 is used to isolate the supporting plate 18, and the two ends of the partition plate 19 are respectively movably connected to the two supporting plates 18, and the supporting plate 18 and the top of the L-shaped plate 3 are limited at both ends of the partition plate 19 to ensure that the partition plate 19 can move stably, so as to realize opening the slot 301 and sealing the slot. The effect of 301 is achieved. A linkage block 20 is fixedly installed on the side of the baffle plate 19 away from the forward inclined plate 2. A first hydraulic cylinder 21 is fixedly installed on the side of the L-shaped plate 3. The piston shaft of the first hydraulic cylinder 21 is fixedly connected to the linkage block 20. When the floating mud on the bottom surface is sucked and removed, the baffle plate 19 is driven to move to the bottom of the slot 301 by controlling the first hydraulic cylinder 21 to achieve the effect of sealing the slot 301. The sealing of the slot 301 does not need to be sealed. It is only necessary to ensure that when the hydraulic sewage pump 5 is working, most of the floating mud on the bottom surface can enter the sewage pumping bin through the first through groove 201. The sewage pumping bin and the sewage collecting bin are not completely sealed, and the negative pressure suction of the sewage pumping bin is conducive to the suspended matter in the water entering the sewage collecting bin.

[0039] When a sufficient amount of suspended solids in the water is collected in the sewage collection bin, the operator can control the chain or cable connected to the U-shaped fixing piece 12 on the ship, and pull the U-shaped fixing piece 12 to flip the bottom plate 1 and the forward tilting plate 2 as a whole, and cooperate with the gravity of the second counterweight block 16 to make the forward tilting plate 2 stick to the bottom of the water, and then control the first hydraulic cylinder 21 to drive the piston shaft to pull the linkage block 20 to drive the partition plate 19 to move and open the slot 301. At this time, under the suction action of the hydraulic sewage pump 5, compared with the bottom silt entering the sewage collection bin through the first through groove 201 and the second through groove 203, water is more likely to enter through the filter screen 10 The sewage in the sewage collecting bin enters the sewage pumping bin through the slot 301 and is pumped out by the hydraulic sewage pump 5, thereby pumping the suspended floating mud on the bottom surface collected in the sewage collecting bin to the ship, making the cleaning of the floating mud on the bottom surface more thorough, and the cleaning efficiency of the suspended floating mud on the bottom surface is higher and the cost is lower. At the same time, water enters the sewage collecting bin through the filter screen 10, and the filter screen 10 is backwashed with water to avoid the clogging problem of the filter screen 10, so that when the floating mud on the bottom surface is subsequently sucked out, the suspended floating mud on the bottom surface can continue to be efficiently filtered and intercepted, which is suitable for continuous cleaning of the floating mud on the bottom surface in large waters.

[0040] For example 2, please refer to Figure 7-Figure 8On the basis of the first embodiment, at least two triangular support plates 22 are installed on the top of the L-shaped plate 3, and a support plate 23 is fixedly installed on the triangular support plate 22. The support plate 23 is arranged parallel to the positioning plate 8. A plurality of groups of movable door panels 24 are installed on the forward tilting plate 2 through hinges. The movable door panels 24 are located in the sewage collecting bin. The number of groups of movable door panels 24 is the same as the number of second through grooves 203 and the positions correspond one to one. The number of each group of movable door panels 24 is two, and the two movable door panels 24 in each group are respectively arranged on both sides of the corresponding second through grooves 203. A limit block 25 for limiting the movable door panel 24 is fixedly installed on the top of the support plate 23, so that the opening angle of the movable door panel 24 does not exceed ninety degrees.

[0041] See also Figure 9-10 A positioning transverse plate 26 is fixedly installed on the tilt plate 2, which is away from the side cover plate 11. The positioning transverse plate 26 is arranged in the middle of the second through groove 203. U-shaped mounting plates 27 are fixedly installed at both ends of the positioning transverse plate 26. Second hydraulic cylinders 28 are fixedly installed on the two U-shaped mounting plates 27 on the side away from the positioning transverse plate 26. The piston shafts of the two second hydraulic cylinders 28 are fixedly connected with a movable transverse plate 29 located on one side of the positioning transverse plate 26. The positioning transverse plate 26 is movably sleeved with linkage shafts 30 with the same number and corresponding positions as the second through grooves 203. One end of the linkage shaft 30 is fixedly connected to one side of the movable transverse plate 29, and the other end of the linkage shaft 30 is fixedly connected to two pull ropes 31. The ends of the two pull ropes 31 away from the linkage shaft 30 are fixedly connected to the movable door panels 24 at corresponding positions.

[0042] When it is necessary to clean the floating mud suspended matter intercepted in the sewage collection bin, the two second hydraulic cylinders 28 are controlled to drive the piston shaft to pull the movable horizontal plate 29 to move away from the positioning horizontal plate 26, thereby driving the linkage shaft 30 to pull the movable door plate 24 to close and isolate the second through groove 203. By actively controlling the second through groove 203 to be isolated, when the first through groove 201 is blocked by the underwater silt, the isolation plate 19 is controlled to open the notch 301, so that the sewage suction bin and the sewage collection bin are connected. Under the suction action of the hydraulic sewage pump 5, the negative pressure suction force in the sewage suction bin makes Water can more easily enter the filter screen 10 and enter the sewage collecting bin, driving the suspended floating mud on the bottom surface intercepted in the sewage collecting bin to enter the sewage pumping bin, and then be pumped to the ship on the water surface through the sewage discharge pipe 6, so as to clean the floating mud on the bottom surface. Compared with the first embodiment, a structure of actively controlling the second through groove 203 is added. There is no need to flip the bottom plate 1 to make the forward inclined plate 2 fit to the bottom of the water. The second through groove 203 is blocked by the bottom silt layer, so that the suspended floating mud on the bottom surface collected in the sewage collecting bin can be cleaned, which is convenient for use in an environment with an uneven bottom and relatively loose bottom silt.

Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
