Description

Technical Field

[0001] This utility model relates to the field of water surface cleaning, and in particular to a pollutant collection device for sewage outlets into rivers. Background Technology

[0002] With rapid socio-economic development, people's demands for water environmental quality are increasing. In daily life, kitchen wastewater, toilet wastewater, public toilet wastewater, and industrial wastewater all require treatment, and corresponding wastewater treatment facilities, including dedicated wastewater treatment ponds or government-built domestic and industrial wastewater treatment plants, must be constructed according to relevant requirements. However, during the rainy season, existing wastewater treatment systems often struggle to cope with sudden downpours, leading to large amounts of untreated pollutants entering rivers through discharge outlets. This problem is particularly prominent in densely populated old urban areas and older residential communities. Current market solutions primarily rely on manual collection, which is not only time-consuming and inefficient but also poses risks to the safety of workers. There is an urgent need to develop a highly efficient, dedicated pollutant collection device to solve this problem. Utility Model Content

[0003] Based on this, and in response to the above problems, this utility model provides a pollutant collection device for a river discharge outlet, comprising a collection float and a fence; the collection float is located downstream of the river discharge outlet, and includes a collection port and a collection chamber, with the collection port communicating with the collection chamber; the fence includes a first fence and a second fence, one end of the first fence and the second fence being respectively connected to both sides of the collection port, the other end of the first fence being connected to the downstream side of the bank foundation on one side of the discharge outlet, and the other end of the second fence being connected to the bank foundation on the opposite side of the discharge outlet.

[0004] With this setup, pollutants discharged from the sewage outlet are collected at the collection port after passing through the first and second fences, and then enter the collection chamber for centralized collection. This improves the collection efficiency of pollutants, eliminates the need for manual retrieval during the flood season, and ensures personal safety.

[0005] In one embodiment of this utility model, the collection chamber is provided with a filter screen, a diversion pump and a drain pipe. The diversion 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. The filter screen is located in the collection chamber to separate pollutants from the diversion pump.

[0006] With this setup, the filter screen can remove moisture from the pollutants, and the water entering the collection chamber can be discharged from the hull through the drain pipe using a diversion pump. This frees up the space occupied by the water in the collection chamber in a timely manner, preventing the collection chamber from being pushed back to the outside of the collection port due to excessive water. Consequently, the pollutants will settle on the filter screen, maximizing the use of the collection chamber space. Furthermore, the drainage process allows water to flow in the collection chamber, and pollutants can drift into the collection chamber through the water flow.

[0007] In one embodiment of this utility model, the collecting float further includes a flow gate, which is rotatably disposed below the collecting port to realize the opening and closing of the collecting port.

[0008] With this setup, when it is necessary to collect pollutants, the diversion gate is opened and its rotation angle is adjusted so that it is lower than the pollutants. This allows the pollutants to pass through the diversion gate and enter the collection chamber, keeping most of the water outside the gate, increasing the concentration of pollutants entering the collection chamber, and improving collection efficiency.

[0009] In one embodiment of this utility model, the collecting float further includes a conveying component, which conveys the pollutants in the collecting chamber to a designated collection point.

[0010] With this setup, the transporter can transport pollutants from the collection chamber to collaborating vessels or designated shore-based collection points, allowing pollutants settled in the collection chamber to be continuously discharged, thus enabling the continuous collection of new pollutants and improving collection efficiency.

[0011] In one embodiment of this utility model, the pollutant collection device for the river discharge outlet further includes a first guide pile, the bottom of which is inserted into the riverbed for fixation, and the collection float is provided with a guide through hole that cooperates with the first guide pile.

[0012] With this setup, since the guide hole is fitted onto the first guide pile, the collecting float can move up and down on the first guide pile according to the water level. Furthermore, due to the limiting effect of the first guide pile, it can maintain its position even when the water flow is large during the flood season, preventing the fence from being torn apart and ensuring normal operation during the flood season.

[0013] In one embodiment of this utility model, the pollutant collection device for the river discharge outlet further includes a second guide pile, the bottom of which is inserted into the bank foundation for fixation, and the end of the fence away from the collection float is sleeved on the second guide pile.

[0014] With this setup, since the fence is fitted onto the second guide post, the end of the fence furthest from the collection float can move up and down on the second guide post according to the water level. Both ends of the fence can remain horizontal, and the pollutant interception effect will not be poor due to a large tilt angle.

[0015] In one embodiment of this utility model, there are multiple first guide piles, and the number of guide through holes is the same as the number of first guide piles.

[0016] With this setup, multiple first guide piles and multiple guide through holes work together to make the collection float more securely fixed and prevent it from rotating due to a single fixed point.

[0017] In one embodiment of the present invention, the fence includes a buoyancy member, an interception member, and a counterweight member. 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 configuration, the buoyancy component provides buoyancy to the entire fence, allowing it to be partially above the water surface, preventing pollutants from crossing the fence. The counterweight component pulls the interceptor downwards, ensuring the fence remains vertical in the water and preventing pollutants from escaping from the bottom of the fence.

[0019] In one embodiment of this utility model, the buoyancy component includes an upper rope and a float, the float being disposed on the upper rope, and the counterweight component includes a lower rope and a counterweight block, the counterweight block being disposed on the lower rope.

[0020] This design strengthens the connection between the upper and lower ropes, ensuring that the fence will not break due to excessive stress during the flood season.

[0021] In one embodiment of this utility model, the interceptor is provided with a plurality of perforations, forming a mesh structure.

[0022] This design reduces the resistance of the fence due to the mesh structure, thereby reducing the tensile force on the entire fence and extending its service life. Attached Figure Description

[0034] like Figure 1-3 As shown, this utility model provides a pollutant collection device for a sewage outlet into a river, including a collection float 1 and a fence 2. The collection float 1 is located downstream of the sewage outlet into the river and includes a collection port 11 and a collection chamber 12, with the collection port 11 and the collection chamber 12 connected. The fence 2 includes 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 collection port 11, the other end of the first fence 21 is connected to the downstream side of the bank foundation on one side of the sewage outlet, and the other end of the second fence 22 is connected to the bank foundation on the opposite side of the sewage outlet.

[0035] It should be noted that there are generally multiple sewage outlets in the river channel. Alternatively, a separate pollutant collection device can be installed at each outlet, or multiple outlets can share a single device, which simply needs to be placed downstream of the downstreammost outlet. The same principle applies when there are sewage outlets on both sides of the river channel; each outlet can have its own device, or both outlets can share a single device. To facilitate the passage of vessels and other vessels through the river channel, the other end of the first fence 21 and the second fence 22 can be detachably connected to the bank. When passage is required, the connection to the bank can be removed; this connection and detachment can be performed by a remotely controlled surface robot.

[0036] Understandably, pollutants discharged from the sewage outlet are collected at the collection port 11 after passing through the first fence 21 and the second fence 22, and then enter the collection chamber 12 for centralized collection. This improves the collection efficiency of pollutants, eliminates the need for manual retrieval during the flood season, and ensures personal safety.

[0037] In one embodiment of the present invention, the collection chamber 12 is provided with a filter screen 121, a diversion pump 122 and a drain pipe 123. One end of the diversion pump 122 is connected to 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 chamber 12 to separate pollutants from the diversion pump 122.

[0038] It should be noted that the filter screen 121 can be of various shapes, as long as it can separate pollutants from the drainage pump 122. In this invention, the filter screen 121 is frame-shaped. Preferably, the bottom of the collection chamber 12 is also provided with a water inlet valve (not shown in the figure). Opening the water inlet valve allows water to be poured into the collection float 1 from the bottom of the collection chamber 12, increasing the draft of the collection float 1. Water can then flow in from the collection port 11, maintaining dynamic balance under the action of the drainage pump 122, and continuing to work. There can be multiple drainage pumps 122, each connected to the drain pipe 123. This invention does not limit the scope of the application.

[0039] Understandably, the filter screen 121 can filter out the water in the pollutants. The water entering the collection chamber 12 can be discharged from the ship's exterior through the drain pipe 123 by the diversion pump 122, which frees up the space occupied by the water in the collection chamber 12 in time. This prevents the collection chamber 12 from being too full and pushing the pollutants to the outside of the collection port 11. Consequently, the pollutants settle on the filter screen 121, maximizing the use of the space in the collection chamber 12. Furthermore, the drainage process allows the water to flow in the collection chamber 12, and the pollutants can drift into the collection chamber 12 through the water flow.

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

[0041] It should be noted that an adjusting rod is provided between the diversion gate 13 and the collection float 1. The adjusting rod can control the opening and closing of the diversion gate 13 and adjust the opening and closing size of the diversion gate 13, fixing the diversion gate 13 at a specific angle. Therefore, according to the degree of pollutant accumulation, the diversion gate 13 can be adjusted to be slightly lower than the pollutants, allowing the pollutants to smoothly enter the collection chamber 12. When the diversion gate 13 is closed, it can prevent the pollutants in the collection chamber 12 from flowing out of the collection float 1.

[0042] Understandably, when it is necessary to collect pollutants, the diversion gate 13 is opened and the rotation angle of the diversion gate 13 is adjusted so that it is lower than the pollutants, so that the pollutants can just pass through the diversion gate 13 and enter the collection chamber 12, blocking most of the water outside the diversion gate 13, increasing the concentration of pollutants entering the collection chamber 12, and improving the collection efficiency.

[0043] In one embodiment of the present invention, the collecting float 1 further includes a conveying member 14, which conveys pollutants in the collecting chamber 12 to a designated collection point.

[0044] It should be noted that the preferred conveyor 14 is a tracked conveyor with a mesh-like track and multiple feeding plates on it. The pollutants are conveyed to the designated collection point by the feeding plates, and the mesh structure can filter out the moisture in the pollutants.

[0045] Understandably, the transport component 14 can transport pollutants in the collection chamber 12 to a cooperating vessel or a designated shore-based collection point, allowing the pollutants settled in the collection chamber 12 to be continuously discharged, thereby continuously collecting new pollutants and improving collection efficiency.

[0046] In one embodiment of this utility model, the pollutant collection device for the river discharge outlet further includes a first guide pile 3, the bottom of which is inserted into the riverbed for fixation, and the collection float 1 is provided with a guide through hole 15 that cooperates with the first guide pile 3.

[0047] Understandably, since the guide hole 15 is fitted onto 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. Furthermore, due to the limiting effect of the first guide pile 3, it can maintain its position even when the water flow is large during the flood season, preventing the fence 2 from being torn apart and ensuring normal operation during the flood season.

[0048] In one embodiment of this utility model, the pollutant collection device for the river discharge outlet further includes a second guide pile 4, the bottom of which is inserted into the bank 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] Understandably, since the fence 2 is attached to 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. Both ends of the fence 2 can remain horizontal, and the pollutant interception effect will not be poor due to a large tilt angle.

[0050] In one embodiment of this utility model, 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, there are four first guide piles 3, which are respectively set at the four corners of the collecting float 1 to comprehensively limit the movement of the collecting float 1 and ensure normal operation during the flood season. Of course, more first guide piles 3 can also be set, depending on the actual situation.

[0052] Understandably, the combination of multiple first guide piles 3 and multiple guide through holes 15 makes the collection float 1 more securely fixed and prevents it from rotating due to a single 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 component 23 is made of a material with a density less than that of water, such as foam, while the counterweight component 25 is made of a material with a density greater than that of water, such as metal.

[0055] Understandably, the buoyancy component 23 provides buoyancy to the entire fence 2, allowing the fence 2 to be partially above the water surface, preventing pollutants from the water surface from crossing the fence 2. The counterweight component 25 can pull the interceptor component 24 downward, ensuring that the fence 2 is vertical in the water and preventing pollutants from escaping from the bottom of the fence 2.

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

[0057] Understandably, the upper rope 231 and the lower rope 251 strengthen the connection of the fence 2, ensuring that it will not be torn apart due to excessive stress during the flood season.

[0058] In one embodiment of this utility model, the interceptor 24 is provided with a plurality of perforations 241, forming a mesh structure.

[0059] Understandably, the mesh structure can reduce the resistance of the fence 2, thereby reducing the tensile force on the entire fence 2 and increasing its service life.

[0060] The working process of the pollutant collection device at the river discharge outlet is as follows: When the flood season arrives, a large amount of untreated pollutants enter the river through the discharge outlet. The personnel managing the discharge outlet can notify the sanitation department staff in advance to be on duty promptly. The diversion gate 13 of the collection float 1 is opened, and the rotation angle of the diversion gate 13 is adjusted according to the actual thickness of the pollutants, ensuring that the pollutants just pass through the gate 13. The water below is blocked outside the gate 13. The diversion pump 122 is started, and the water containing pollutants discharged from the discharge outlet passes through the enclosure 2 and enters the collection chamber 12 through the collection port 11. As the pollutants accumulate on the filter screen 121 of the collection chamber 12 to a certain thickness, the conveyor 14 is activated to transport the pollutants to a cooperating vessel or a designated collection point on the shore for centralized treatment. After the collection work is completed, the conveyor 14, diversion pump 122, and diversion gate 13 are shut down sequentially.

[0061] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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 embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
