Description

Technical Field

[0001] The invention relates to the field of water surface cleaning, in particular to a pollutant collection device at a sewage outlet into a river. Background Art

[0002] With the rapid development of social economy, people's requirements for water environment quality are increasing. In daily life, kitchen sewage, flush toilet wastewater, public toilet sewage and industrial production sewage all need to be treated, and corresponding sewage treatment facilities should be built in accordance with relevant requirements, including special sewage treatment pools or domestic and industrial sewage treatment stations built by the government. However, during the rainy season, the existing sewage treatment system is often unable to cope with the sudden test of heavy rain, resulting in a large amount of untreated pollutants entering the river through the sewage outlet, especially in densely populated old urban areas and old communities. This problem is particularly prominent. At present, the solution on the market is still mainly manual salvage. This method is not only time-consuming and inefficient, but also the safety of the operators is not fully guaranteed. It is urgent to develop an efficient and dedicated pollutant collection device to solve this problem. Summary of the invention

[0003] Based on this, in order to solve the above problems, the present invention provides a pollutant collection device for a sewage outlet into a river, comprising a collecting float and a fence; the collecting float is arranged downstream of the sewage outlet into the river, the collecting float comprises a collecting port and a collecting bin, and the collecting port is connected to the collecting bin; the fence comprises a first fence and a second fence, one end of the first fence and the second fence are respectively connected to both sides of the collecting port, the other end of the first fence is connected to the downstream of the shore on one side of the sewage outlet, and the other end of the second fence is connected to the shore on the opposite side of the sewage outlet.

[0004] With such an arrangement, pollutants discharged from the sewage outlet are collected at the collection port through the first fence and the second fence, and enter the collection bin for centralized collection, thereby improving the collection efficiency of pollutants, eliminating the need for manual salvage during the flood season, and ensuring personal safety.

[0005] In one embodiment of the present invention, a filter screen, a drainage pump and a drain pipe are arranged in the collection bin, the drainage pump is connected to one end of the drain pipe, and the other end of the drain pipe is connected to the outside of the collection float, and the filter screen is arranged in the collection bin to separate pollutants from the drainage pump.

[0006] With such an arrangement, the filter can filter out moisture from the pollutants, and the water entering the collection bin can be discharged out of the hull through the drain pipe using a drainage pump, thereby promptly freeing up the space occupied by the water in the collection bin so that the collection bin will not push the pollutants out of the collection port due to being too full of water, and the pollutants will be deposited on the filter, thereby maximizing the use of the collection bin space. In addition, during the drainage process, the water is allowed to flow in the collection bin, and the pollutants can drift into the collection bin through the water flow.

[0007] In one embodiment of the present invention, the collection float further includes a drainage door, and the drainage door is rotatably disposed below the collection port to achieve opening and closing of the collection port.

[0008] With this arrangement, when pollutants need to be collected, the drainage door is opened and the rotation angle of the drainage door is adjusted to be lower than the pollutants, so that the pollutants can just pass through the drainage door and enter the collection bin, blocking most of the water outside the drainage door, thereby increasing the concentration of pollutants entering the collection bin and improving the collection efficiency.

[0009] In one embodiment of the present invention, the collection float further includes a conveying member, and the conveying member conveys the pollutants in the collection bin to a designated collection location.

[0010] With such an arrangement, the conveyor can transport the pollutants in the collection bin to a cooperating vessel or a designated collection point on the shore, so that the pollutants deposited in the collection bin can be continuously discharged, and new pollutants can be continuously collected, thereby improving the collection efficiency.

[0011] In one embodiment of the present invention, the pollutant collection device at the sewage outlet into the river also includes a first guide pile, the bottom of which is inserted into the riverbed and fixed, and the collecting float is provided with a guide through hole that cooperates with the first guide pile.

[0012] With such arrangement, since the guide through hole is sleeved on the first guide pile, the collecting float can move up and down on the first guide pile according to the water level, and due to the limiting position of the first guide pile, it is ensured that it can still maintain its position when the water flow is large during the flood season, and the fence will not be torn off, thereby ensuring normal operation during the flood season.

[0013] In one embodiment of the present invention, the pollutant collection device at the sewage outlet into the river also includes a second guide pile, the bottom of the second guide pile is inserted into the shore foundation for fixation, and the end of the fence away from the collecting float is sleeved on the second guide pile.

[0014] With this arrangement, since the fence is sleeved on the second guide pile, the end of the fence away from the collecting float can move up and down on the second guide pile according to the water level, and both ends of the fence can remain horizontal, and the pollutant interception effect will not be poor due to a large inclination angle.

[0015] In one embodiment of the present invention, there are a plurality of first guide piles, and the number of the guide through holes is the same as the number of the first guide piles.

[0016] With such arrangement, the plurality of first guide piles cooperate with the plurality of guide through holes, so that the collection float is fixed more firmly and will not rotate due to a fixed point.

[0017] In one embodiment of the present invention, the fence includes a buoyancy member, an interception member and a counterweight member, wherein the interception member extends downward from the bottom end of the buoyancy member, and the lower end of the interception member is connected to the counterweight member.

[0018] With this arrangement, the buoyancy element provides buoyancy for the entire fence, allowing the fence to be partially above the water surface, and pollutants on the water surface will not pass over the fence. The counterweight element can stretch the interception element downward to ensure that the fence is in a vertical state in the water, ensuring that pollutants will not escape from the bottom of the fence.

[0019] In one embodiment of the present invention, the buoyancy member includes an upper rope and a floating body, wherein the floating body is arranged on the upper rope, and the counterweight member includes a lower rope and a counterweight block, wherein the counterweight block is arranged on the lower rope.

[0020] With this arrangement, the upper rope and the lower rope strengthen the connection strength of the fence, ensuring that it will not be torn apart due to excessive force during the flood season.

[0021] In one embodiment of the present invention, the intercepting member is provided with a plurality of perforations, forming a mesh structure.

[0022] With such arrangement, the mesh structure can reduce the resistance experienced by the fence, thereby reducing the tension experienced by the entire fence and increasing the service life of the fence. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] like Figure 1-3 As shown, the present invention provides a pollutant collection device for a sewage outlet into a river, comprising a collecting float 1 and a fence 2; the collecting float 1 is arranged downstream of the sewage outlet into the river, the collecting float 1 comprises a collecting port 11 and a collecting bin 12, and the collecting port 11 is connected to the collecting bin 12; the fence 2 comprises a first fence 21 and a second fence 22, one end of the first fence 21 and the second fence 22 are respectively connected to the two sides of the collecting port 11, the other end of the first fence 21 is connected to the downstream of the shore foundation on one side of the sewage outlet, and the other end of the second fence 22 is connected to the shore foundation on the opposite side of the sewage outlet.

[0035] It should be noted that there are generally multiple sewage outlets in the river. You can choose to prepare a pollutant collection device for each sewage outlet, or you can choose to share a pollutant collection device for multiple sewage outlets, which only needs to be set downstream of the most downstream sewage outlet. The same is true when there are sewage outlets on both sides of the river. Each sewage outlet can be set separately or the sewage outlets on both sides can share one. In order to facilitate the passage of ships and the like through the river, the other end of the first fence 21 and the second fence 22 can be set to be detachably connected to the shore. When it is necessary to pass through at ordinary times, it is not necessary to connect to the shore. The connection and disassembly actions can be completed by setting a surface remote control robot.

[0036] It can be understood that the pollutants discharged from the sewage outlet are collected to the collection port 11 through the first fence 21 and the second fence 22, and enter the collection bin 12 for centralized collection, thereby improving the collection efficiency of the pollutants, eliminating the need for manual salvage during the flood season, and ensuring personal safety.

[0037] In one embodiment of the present invention, a filter screen 121, a drainage pump 122 and a drain pipe 123 are provided in the collection bin 12. The drainage pump 122 is connected to one end of the drain pipe 123, and the other end of the drain pipe 123 is connected to the outside of the collection float 1. The filter screen 121 is provided in the collection bin 12 to separate pollutants from the drainage pump 122.

[0038] It should be noted that the filter 121 can be selected to use various shapes, as long as it can separate the pollutants from the drainage pump 122. In the present invention, the filter 121 is set in a frame shape. Preferably, a water filling valve (not shown in the figure) is also provided at the bottom of the collection bin 12. When the water filling valve is opened, water can be poured into the collection float 1 from the bottom of the collection bin 12, so that the draft of the collection float 1 becomes deeper, and water can flow in from the collection port 11. Under the action of the drainage pump 122, dynamic balance is maintained and the work is continued. There can be multiple drainage pumps 122, and the multiple drainage pumps 122 are respectively connected to the drain pipe 123, which is not limited by the present invention.

[0039] It can be understood that the filter 121 can filter out the moisture in the pollutants, and the water entering the collection bin 12 can be discharged out of the hull through the drain pipe 123 using the drainage pump 122, so as to promptly vacate the space occupied by the water in the collection bin 12, so that the collection bin 12 will not push the pollutants to the outside of the collection port 11 due to being too full of water, and the pollutants will be precipitated on the filter 121, thereby maximizing the utilization of the space in the collection bin 12, and during the drainage process, the water is allowed to flow in the collection bin 12, and the pollutants can drift into the collection bin 12 through the water flow.

[0040] In one embodiment of the present invention, the collection float 1 further includes a drainage door 13 , which is rotatably disposed below the collection port 11 to realize the opening and closing of the collection port 11 .

[0041] It should be noted that an adjustment rod is provided between the drainage door 13 and the collection float 1, and the adjustment rod can control the opening and closing of the drainage door 13, and can adjust the opening and closing size of the drainage door 13. The drainage door 13 is fixed at a specific angle, so the drainage door 13 can be adjusted to be just slightly lower than the pollutants according to the accumulation degree of the pollutants, so that the pollutants can smoothly enter the collection bin 12. When the drainage door 13 is closed, the pollutants in the collection bin 12 can be prevented from flowing out of the collection float 1.

[0042] It can be understood that when it is necessary to collect pollutants, the drainage door 13 is opened and the rotation angle of the drainage door 13 is adjusted to be lower than the pollutants, so that the pollutants can just pass through the drainage door 13 and enter the collection bin 12, blocking most of the water outside the drainage door 13, thereby increasing the concentration of pollutants entering the collection bin 12 and improving the collection efficiency.

[0043] In one embodiment of the present invention, the collection float 1 further includes a conveying member 14, and the conveying member 14 conveys the pollutants in the collection bin 12 to a designated collection location.

[0044] It should be noted that the preferred conveying member 14 is configured as a crawler conveyor, the crawler is configured in a mesh shape, and a plurality of loading plates are arranged thereon. The pollutants are transported to a designated collection point by the loading plates, and the mesh structure can filter out moisture from the pollutants.

[0045] It is understandable that the conveying member 14 can transport the pollutants in the collection bin 12 to a cooperating vessel or a designated collection point on the shore, so that the pollutants accumulated in the collection bin 12 can be continuously discharged, and new pollutants can be continuously collected, thereby improving the collection efficiency.

[0046] In one embodiment of the present invention, the pollutant collection device for the sewage outlet into the river also includes a first guide pile 3, the bottom of the first guide pile 3 is inserted into the riverbed and fixed, and the collecting float 1 is provided with a guide through hole 15 that cooperates with the first guide pile 3.

[0047] It can be understood that since the guide through hole 15 is mounted on the first guide pile 3, the collecting float 1 can move up and down on the first guide pile 3 according to the water level, and due to the limiting of the first guide pile 3, it is ensured that the position can be maintained when the water flow is large during the flood season, and the fence 2 will not be torn off, thereby ensuring normal operation during the flood season.

[0048] In one embodiment of the present invention, the pollutant collection device at the river discharge outlet further includes a second guide pile 4 , the bottom of the second guide pile 4 is inserted into the shore foundation for fixation, and the end of the fence 2 away from the collection float 1 is sleeved on the second guide pile 4 .

[0049] It can be understood that since the fence 2 is sleeved on the second guide pile 4, the end of the fence 2 away from the collecting float 1 can move up and down on the second guide pile 4 according to the water level, and the two ends of the fence 2 can remain horizontal, and the pollutant interception effect will not be poor due to a large inclination angle.

[0050] In one embodiment of the present invention, there are multiple first guide piles 3 , and the number of guide through holes 15 is the same as the number of first guide piles 3 .

[0051] It should be noted that in this embodiment, the number of first guide piles 3 is 4, which are respectively arranged at the four corners of the collection float 1 to fully limit the collection float 1 and ensure normal operation during the flood season. Of course, more first guide piles 3 can be arranged, which can be selected according to actual conditions.

[0052] It can be understood that the plurality of first guide piles 3 cooperate with the plurality of guide through holes 15 so that the collection float 1 is fixed more firmly and will not rotate due to a fixed point.

[0053] In one embodiment of the present invention, the fence 2 includes a buoyancy member 23 , an interception member 24 and a counterweight member 25 . The interception member 24 extends downward from the bottom end of the buoyancy member 23 , and the lower end of the interception member 24 is connected to the counterweight member 25 .

[0054] It should be noted that the buoyancy member 23 is made of a material with a density lower than that of water, and foam or the like is usually used, while the weight member 25 is made of a material with a density higher than that of water, and metal material is usually used.

[0055] It can be understood that the buoyancy member 23 provides buoyancy for the entire fence 2, so that the fence 2 can be partially above the water surface, and pollutants on the water surface will not pass over the fence 2. The counterweight member 25 can stretch the interception member 24 downward to ensure that the fence 2 is in a vertical state in the water, ensuring that pollutants will not escape from the lower part of the fence 2.

[0056] In one embodiment of the present invention, the buoyancy member 23 includes an upper rope 231 and a float 232 , wherein the float 232 is disposed on the upper rope 231 , and the counterweight member 25 includes a lower rope 251 and a counterweight block 252 , wherein the counterweight block 252 is disposed on the lower rope 251 .

[0057] It can be understood that the upper rope 231 and the lower rope 251 strengthen the connection strength of the fence 2 to ensure that it will not be torn apart due to excessive force during the flood season.

[0058] In one embodiment of the present invention, the intercepting member 24 is provided with a plurality of through holes 241 , forming a mesh structure.

[0059] It can be understood that the mesh structure can reduce the resistance experienced by the fence 2, thereby reducing the tension experienced by the entire fence 2 and increasing the service life of the fence 2.

[0060] The working process of the pollutant collection device at the river discharge outlet is as follows: when the flood season comes, a large amount of untreated pollutants enter the river through the discharge outlet. The staff managing the discharge outlet can notify the staff of the cleaning department in advance to go to work in time, open the drainage gate 13 of the collection float 1, and adjust the rotation angle of the drainage gate 13 according to the actual thickness of the pollutants, so that the pollutants can just pass through the drainage gate 13, and the water at the bottom is blocked outside the drainage gate 13. The drainage pump 122 is started, and the water with pollutants is discharged from the discharge outlet and converged by the fence 2 and enters the collection bin 12 from the collection port 11. As the pollutants continue to accumulate on the filter screen 121 of the collection bin 12 to a certain extent, the conveying member 14 is opened to transport the pollutants to the cooperative ship or the designated collection point on the shore for centralized treatment. When the collection work is completed, the conveying member 14, the drainage pump 122 and the drainage gate 13 are shut down in sequence.

[0061] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
