Description

Technical Field

[0001] The present invention relates to the technical field of river channel cleaning, and in particular to a dirt cleaning device for river channel and river ecological restoration. Background Art

[0002] River ecological restoration is a comprehensive project aimed at restoring the ecological health of rivers. Its goals are diverse, including restoring the structure of the ecosystem, rebuilding the natural river morphology, riverbank vegetation and aquatic biological communities; improving water quality, reducing pollution and enhancing self-purification capacity; enhancing ecological service functions and playing a role in water conservation and flood control. If there is oil on the surface of the river, a buoy must be placed in the river to block the oil before cleaning, and then an automatic cleaning boat must be placed in the river to carry out cleaning work. When the automatic cleaning boat approaches the oily area, it slowly lowers the adsorption belt or adsorption pad to contact the water surface. Due to the surface tension difference and van der Waals force between the adsorption material and the oil, the oil molecules spontaneously migrate to the adsorption material , it is adsorbed to the pores and surface of the material under the action of Van der Waals force. As the cleaning ship moves, the adsorption material continues to contact new oil and continuously adsorbs it, and the oil gradually accumulates. When the adsorption material reaches saturation and the adsorption capacity decreases, the cleaning ship control system sends a signal to start the recovery device, and slowly retracts the adsorption belt or adsorption pad onto the ship through the mechanical transmission device. During the process, it passes through the oil scraping mechanism, which uses scrapers and other components to scrape the surface of the adsorption material to separate the oil and flow into the ship's oil storage tank for storage. After the oil is scraped, the adsorption material is regenerated through cleaning, drying and other regeneration treatments to restore its adsorption performance so that it can be used again. After the oil is cleaned, the buoy is taken out of the river and cleaned.

[0003] When the buoy intercepts the oil, the oil will float near the buoy. When the cleaning boat passes by the buoy, there is a gap between the adsorption belt or adsorption pad of the cleaning boat and the buoy. Therefore, the oil on the river cannot be cleaned up. The buoy needs to be moved to spread the oil at the buoy, which is cumbersome to operate. Therefore, the present application provides a kind of sewage cleaning equipment for river ecological restoration to meet the needs. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a dirt cleaning device for river ecological restoration to solve the problem that there is a gap between the buoy and the cleaning boat, which makes it impossible to clean the oil on the river, and the buoy needs to be moved to spread the oil on the buoy, which is cumbersome to operate.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: A dirt cleaning device for river ecological restoration includes a buoy and a pull rope, wherein a plurality of buoys are provided, and the plurality of buoys are sleeved on the surface of the pull rope, and further includes: A protective mechanism, the protective mechanism includes an air pipe fixed on the buoy, the air inlet end of the air pipe is connected to an air supply machine, two groups of hollow rings are movably sleeved on the surface of the buoy, the two groups of hollow rings are staggered, the bottoms of the two groups of hollow rings are connected to hollow long rods, the two hollow long rods are symmetrically arranged about the center of the buoy, the ends of the hollow long rods extend to adjacent buoys, the air pipe is connected to the hollow rings through a pipeline, the hollow long rods and the buoys are staggered, and the bottom of the hollow long rods is provided with long strip holes connected to the inside.

[0006] Preferably, the hollow long rod consists of a long portion, a flexible portion and a short portion, and the flexible portion is located between the long portion and the short portion.

[0007] Preferably, the flexible portion is made of rubber.

[0008] Preferably, a guiding surface 1 is provided at the bottom of the long portion, the flexible portion and the short portion, and the guiding surface 1 is arc-shaped.

[0009] Preferably, a second guide surface is provided at one end of the short portion away from the flexible portion, and the second guide surface is arc-shaped.

[0010] Preferably, a limiting assembly is arranged on the outer side of the long part, the limiting assembly includes a limiting seat fixed on the outer side of the long part, a limiting groove is opened on the limiting seat close to the side of the short part, a limiting block is fixed on the outer side of the short part, and the surface of the limiting block is movably connected to the inner wall of the limiting groove.

[0011] Preferably, the inner wall of the limit groove is provided with a accommodating groove, and a clamping block is movably connected to the inner wall of the accommodating groove. A clamping groove is provided on the surface of the limit block, and two springs are fixed between the side of the clamping block away from the limit block and the accommodating groove, and a pull rod is fixed on the side of the clamping block away from the limit block, and the pull rod movably passes through the limit seat, and the two springs are symmetrically arranged on both sides of the pull rod. After the short part is rotated, the clamping block is clamped into the clamping groove by the elastic force of the spring.

[0012] Preferably, the angle between the card slot and the card block is forty-five degrees.

[0013] Preferably, a guide groove is formed on the inner wall of the limiting groove, a guide block is fixed on the surface of the limiting block, and the surface of the guide block is movably connected to the inner wall of the guide groove.

[0014] Preferably, a plurality of limiting plates are provided on the surface of the buoy, and after the hollow long rod is rotated upward through the hollow ring, the outer surface of the hollow long rod is fitted on the bottom of the limiting plates.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, by setting up an air supply machine, an air pipe and a hollow long pole, after the buoy is placed on the surface of the river, the hollow long pole floats on both sides of the buoy, and the gas will be sprayed out from the long holes of the hollow long pole through the air supply machine and the air pipe. After the gas is sprayed out, it can push the oil away from the buoy, making it convenient for the cleaning ship to clean the oil. Secondly, it can prevent the oil from adhering to the buoy, reducing the trouble of subsequent cleaning of the buoy.

[0016] By setting the hollow ring, before the buoy touches the water surface, the long hole of the hollow long rod opens downward, and through the air supply of the air supply machine and the gas transmission of the air pipe, the gas is sprayed out from the bottom of the hollow long rod, blowing away the oil on the water surface to avoid the buoy from contacting the oil after contacting the water surface, thereby further reducing the trouble of subsequent cleaning of the buoy; when the buoy enters the water, the hollow long rod drives the hollow ring to rotate on the buoy, so that the hollow long rod floats on both sides of the buoy to avoid the oil on both sides of the buoy from contacting the buoy; secondly, the end of the opened hollow long rod extends to the surface of the adjacent buoy, and the hollow long rod can clamp the adjacent buoys. The hollow long rod can limit the position between the buoys to avoid bending between adjacent buoys, so that several buoys are roughly in a straight line, which is convenient for subsequent cleaning of the oil.

[0017] By setting the guide surface one and the guide surface two, when the float contacts the water surface, the guide surface two contacts the water surface first, and the arc-shaped guide surface two can allow the gas to blow more fully onto the water surface to blow away the oil stains. Secondly, between adjacent hollow long rods, the setting of the guide surface two can reduce the contact area between adjacent hollow long rods to avoid jamming between adjacent hollow long rods. Secondly, the guide surface one and the guide surface two can guide the hollow long rods to facilitate the upward rotation of the hollow long rods.

[0018] By setting a long part, a flexible part and a short part, the short part is connected to the long part through the flexible part. When there is a slight displacement between several buoys, the hollow long rod on one side of the buoy will be squeezed together. Through the setting of the flexible part, the long part will not move while the short part rotates, which can further prevent the hollow long rod from tilting up due to mutual squeezing, thereby preventing the hollow long rod from driving the buoy to tilt upward, making the whole more stable during use.

[0019] By setting a limit seat, a limit groove and a limit block, when the hollow long rods are squeezed, the short part will collide with the adjacent long part, and the short part will rotate. During the rotation, the short part will drive the limit block to rotate inside the limit groove, thereby limiting the short part during movement, so that the short part can only move in the horizontal direction, avoiding the short part from tilting upward.

[0020] By arranging the spring, the slot and the block, when the first buoy is launched into the water, the buoy will move to the other side of the river. Before that, the two short parts on the first buoy can be bent upwards. After the short part rotates, the spring will drive the block to be stuck in the slot to prevent the short part from rebounding. When the buoy is moving, the gas ejected from the short part will blow away the oil stains on the end of the buoy to prevent the oil stains from contacting the end of the buoy, which is convenient for subsequent cleaning of the oil stains. Secondly, when the block is against the limit block, it can also increase the resistance of the limit block during movement, avoid unnecessary rotation of the short part, and improve the overall stability during use.

[0021] By providing the guide groove and the guide block, when the short part is rotating, the short part will drive the guide block to slide inside the guide groove through the limit block, so that the short part is more stable during rotation. Secondly, it can also prevent the short part from being stretched, thereby improving stability.

[0022] By setting a limit plate, when the hollow long rod rotates upward, the hollow long rod will fit against the bottom of the limit plate to prevent the hollow long rod from continuing to rotate upward, ensuring that the long hole of the hollow long rod is on the water surface, thereby ensuring the effect of blowing away oil stains.

[0029] In general, a term can be understood, at least in part, from its use in context. For example, depending, at least in part, on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in the singular sense, or can be used to describe a combination of features, structures, or characteristics in the plural sense. Additionally, the term "based on" can be understood as not necessarily intended to convey an exclusive set of factors, but can instead, depending, at least in part, on the context, allow for the presence of other factors that are not necessarily explicitly described.

[0030] like Figure 1-Figure 10As shown, an embodiment of the present invention provides a sewage cleaning device for river ecological restoration, including a buoy 1 and a pull rope, wherein the buoy 1 is provided with a plurality of buoys, and the plurality of buoys 1 are sleeved on the surface of the pull rope, and further comprising: a protective mechanism 2, wherein the protective mechanism 2 comprises an air pipe 3 fixed on the buoy 1, and a holder is provided on the surface of the buoy 1, and the air pipe 3 is clamped in the holder, and an air supply machine (not shown in the figure) is connected to the air inlet end of the air pipe 3, and the air supply machine is an air pump, and when used in the field, it can be used in conjunction with a generator or a battery, and two groups of hollow rings 4 are movably sleeved on the surface of the buoy 1, and the two groups of hollow rings 4 are staggered. The bottom of the hollow ring 4 is connected to a hollow long rod 5, and the two hollow long rods 5 are symmetrically arranged about the center of the buoy 1. The end of the hollow long rod 5 extends to the adjacent buoy 1. The air pipe 3 is connected to the hollow ring 4 through a pipeline. The pipeline is reserved with a certain length. When the hollow ring 4 rotates, the reserved pipeline can be deformed accordingly and will not affect the air supply effect. The hollow long rod 5 and the buoy 1 are staggered. The bottom of the hollow long rod 5 is provided with a long hole 11 connected to the inside. The gas is ejected from the long hole 11. After the gas is sprayed on the water surface, the oil on the water surface can be blown away, which is convenient for subsequent cleaning by the cleaning boat.

[0031] like Figure 5 As shown, in the present embodiment, the hollow long rod 5 is composed of a long portion 6, a flexible portion 7 and a short portion 8, and the flexible portion 7 is located between the long portion 6 and the short portion 8. When a plurality of buoys 1 are slightly displaced in a river channel due to factors such as water flow, the hollow long rods 5 on one side of the buoy 1 are easily squeezed against each other. At this time, the flexible portion 7 plays a key role, which allows the short portion 8 to move and rotate within a certain range without the long portion 6 making obvious movement. In this way, the hollow long rod 5 can be effectively prevented from tilting up due to mutual squeezing, thereby preventing the hollow long rod 5 from driving the buoy 1 to tilt upward, thereby greatly improving the stability of the equipment during use, and ensuring that the equipment can continuously and stably perform the function of blocking and driving away oil pollution.

[0032] like Figure 5 As shown, in this embodiment, the flexible portion 7 is made of rubber material, and the rubber material has good flexibility and elasticity, so that the flexible portion 7 between the short portion 8 and the long portion 6 can easily adapt to the rotation and movement of the short portion 8 under various conditions, and can buffer the pressure through its own elastic deformation when subjected to external forces such as squeezing, thereby ensuring the integrity of the hollow long rod 5 structure, extending the service life of the equipment, and always maintaining the equipment's stable protection and limiting effect on the buoy 1.

[0033] like Figure 5As shown, in this embodiment, a guiding surface 9 is provided at the bottom of the long portion 6, the flexible portion 7 and the short portion 8, and the guiding surface 9 is arc-shaped. When the buoy 1 enters the water, the guiding surface 9 can increase the contact area of ​​the long portion 6, the flexible portion 7 and the short portion 8 when they are in contact with the water surface, so that the long portion 6, the flexible portion 7 and the short portion 8 can float upward more easily, and the long portion 6, the flexible portion 7 and the short portion 8 are enlarged and more stable.

[0034] like Figure 5 As shown, in the present embodiment, a second guide surface 10 is provided at one end of the short portion 8 away from the flexible portion 7. The second guide surface 10 is arc-shaped. The second guide surface 10 first contacts the water surface. Its arc-shaped design allows the gas to be blown toward the water surface more evenly and fully, effectively blowing away the oil stains and reducing the possibility of the float 1 contacting the oil stains. Between adjacent hollow long rods 5, the setting of the second guide surface 10 can significantly reduce the contact area between them, avoiding the jamming phenomenon due to excessive contact area, ensuring that the hollow long rod 5 can rotate and move flexibly, and ensuring the normal operation of the equipment. At the same time, during the upward rotation of the hollow long rod 5, the second guide surface 10 can also play a guiding role, helping the hollow long rod 5 to rotate smoothly to the appropriate position.

[0035] like Figure 6-Figure 9 As shown, in this embodiment, a limiting assembly 12 is arranged on the outside of the long portion 6, and the limiting assembly 12 includes a limiting seat 13 fixed on the outside of the long portion 6, and a limiting groove 14 is provided on the limiting seat 13 close to the side of the short portion 8, and a limiting block 15 is fixed on the outside of the short portion 8. The surface of the limiting block 15 is movably connected to the inner wall of the limiting groove 14. When the hollow long rods 5 are squeezed against each other and the short portion 8 collides and rotates with the adjacent long portion 6, the limiting block 15 will rotate in the limiting groove 14. This design can accurately limit the moving direction of the short portion 8 so that it can only rotate in the horizontal direction, effectively preventing the short portion 8 from tilting upward, maintaining the stable working state of the hollow long rod 5, and thereby ensuring that the equipment as a whole can stably block and clean oil stains.

[0036] like Figure 6 and Fig.10As shown, in this embodiment, the inner wall of the limiting groove 14 is provided with a receiving groove 20, and the inner wall of the receiving groove 20 is movably connected with a clamping block 17, and the surface of the limiting block 15 is provided with a clamping groove 16, and two springs 18 are fixed between the side of the clamping block 17 away from the limiting block 15 and the receiving groove 20, and a pull rod 19 is fixed on the side of the clamping block 17 away from the limiting block 15, and the pull rod 19 movably penetrates the limiting seat 13, and the two springs 18 are symmetrically arranged on both sides of the pull rod 19. After the short part 8 rotates, the clamping block 17 is clamped into the clamping groove 16 by the elastic force of the spring 18, and the clamping block 17 in the receiving groove 20 on the inner wall of the limiting groove 14, the clamping groove 16 on the surface of the limiting block 15, and the connecting clamping block 17 and the spring 18 of the accommodating groove 20 together constitute a locking mechanism. Before the first buoy 1 is launched into the water, its two short parts 8 are bent upward, and the rotation of the short part 8 drives the limit block 15 to move. When the short part 8 is rotated to a suitable angle, the spring 18 will push the block 17 to get into the slot 16 to prevent the short part 8 from rebounding. In this way, during the movement of the buoy 1, the gas ejected from the short part 8 can effectively blow away the oil stains at the end of the buoy 1 to prevent the oil stains from contacting the end of the buoy 1. At the same time, when the block 17 is against the limit block 15, it can increase the resistance of the limit block 15 during movement, avoid unnecessary rotation of the short part 8, and further improve the stability of the equipment during use.

[0037] like Figure 6 As shown, in this embodiment, the angle between the slot 16 and the block 17 is forty-five degrees. When the short portion 8 is rotated to a suitable position, the forty-five-degree angle enables the block 17 to be accurately and firmly inserted into the slot 16, providing sufficient locking force to prevent the short portion 8 from accidentally rebounding. At the same time, when the lock needs to be released, this angle can also ensure the convenience of operation. Only by applying appropriate external force, the block 17 can be smoothly separated from the slot 16, which is convenient for adjustment and maintenance of the equipment.

[0038] like Figure 6 , Figure 8 and Fig. 9 As shown, in this embodiment, a guide groove 21 is opened on the inner wall of the limit groove 14, and a guide block 22 is fixed on the surface of the limit block 15. The surface of the guide block 22 is movably connected to the inner wall of the guide groove 21. The guide groove 21 on the inner wall of the limit groove 14 and the guide block 22 on the surface of the limit block 15 cooperate with each other to provide stable protection for the rotation of the short part 8. During the rotation of the short part 8, the limit block 15 drives the guide block 22 to slide in the guide groove 21, which not only makes the rotation of the short part 8 more stable and smooth, avoiding shaking or jamming, but also prevents the short part 8 from being accidentally stretched during the rotation, protects the structural integrity of the hollow long rod 5, and ensures the long-term stable operation of the equipment.

[0039] like Figure 2As shown, in this embodiment, a plurality of limit plates 23 are arranged on the surface of the buoy 1. After the hollow long rod 5 rotates upward through the hollow ring 4, the outer surface of the hollow long rod 5 is attached to the bottom of the limit plate 23. The plurality of limit plates 23 arranged on the surface of the buoy 1 play a precise limiting role in the rotation of the hollow long rod 5. After the hollow long rod 5 rotates upward through the hollow ring 4, its outer surface will be attached to the bottom of the limit plate 23. This design can prevent the hollow long rod 5 from excessively rotating upward, and ensure that the long strip hole 11 at the bottom of the hollow long rod 5 is always in a suitable position above the water surface, so that the ejected gas can continuously and effectively blow the oil away from the buoy 1, thereby ensuring that the effect of the equipment in cleaning the oil is stable and reliable.

[0040] Working principle: before the buoy 1 enters the water, the air supply machine is connected to the air pipe 3, and air is supplied through the air supply machine. Then, the short part 8 that enters the water first is rotated to make the end of the short part 8 tilt upward, and the flexible part 7 is deformed to adapt to the rotation of the short part 8. After the short part 8 rotates, the short part 8 will drive the limit block 15 to move, and the limit block 15 will rotate in the limit groove 14 of the limit seat 13, and the limit block 15 will drive the guide block 22 to slide inside the guide groove 21. When the short part 8 rotates ninety degrees, the spring 18 will drive the clamping block 17 to clamp into the clamping groove 16 to prevent the short part 8 from rebounding; After that, the buoy 1 will slowly contact the water surface. Before the buoy 1 contacts the water surface, the short portion 8, the flexible portion 7 and the long strip holes 11 on the long portion 6 will eject gas to blow away the oil stains on the water surface. Then, the second guide surface 10 will contact the water surface first. Through the guidance of the second guide surface 10, it is convenient for the hollow long rod 5 to rotate upward through the hollow ring 4. Then, the first guide surface 9 will contact the water surface. Through the second guide surface 10, it can also play a guiding role, increase the contact area of ​​the hollow long rod 5 when it just contacts the water surface, and further facilitate the upward rotation of the hollow long rod 5. When the buoy 1 is completely floating on the water surface, the hollow long rod 5 also rotates upward and floats on both sides of the buoy 1. At this time, the hollow long rod 5 is attached to the bottom of the limit plate 23, and the gas is continuously ejected from the long strip hole 11, which can blow the oil away from the buoy 1. Then, the first buoy 1 is pulled by the pull rope, and the subsequent buoys 1 are put into the water one by one. When the first buoy 1 moves to the other side of the river, the oil on the short part 8 of the buoy 1 can be blown away by the rotating short part 8, so as to prevent the oil from contacting the buoy 1. When the buoy 1 is completely submerged in water, the cleaning boat can be placed in the river to clean the oil pollution; When the oil stains are cleaned, the buoy 1 can be stored up; After the buoy 1 is stored, hold the pull rod 19 with your hand and pull the pull rod 19, which will drive the clamping block 17 to push away from the clamping groove 16, and reset the short part 8; During the cleaning of oil stains, when the water flow impacts the buoy 1, several buoys 1 will bend relative to each other, causing the hollow long rods 5 on the inner side of the bend to squeeze each other. The flexible portion 7 can play a buffering role to prevent the buoy 1 from tilting upward and leaving the water surface after the hollow long rod 5 is squeezed, thereby improving the stability during use. Secondly, the end of the hollow long rod 5 is located on the surface of the adjacent buoy 1, which can play a limiting role, thereby preventing relative bending between several buoys 1 and further improving stability.

[0041] The present invention encompasses any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details.

[0042] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
