Description

Technical Field

[0001] The invention relates to the technical field of municipal drainage, in particular to an assembled surface source pollution treatment device. Background Art

[0002] With the continuous acceleration of urbanization, non-point source pollution is becoming increasingly serious. Especially during rainfall, pollutants carried in rainwater and surface runoff will be washed into river outlets and water bodies in large quantities, causing a sharp decline in water quality and serious threats to the ecological environment. In order to effectively control non-point source pollution, assembled non-point source pollution treatment devices have become a solution that has attracted much attention.

[0003] Prefabricated non-point source pollution treatment devices are usually installed in rainwater outlets, and their structural design includes multiple filter holes for filtering impurities and pollutants in rainwater. Although this design can effectively capture larger particles and sediments, in actual applications, when it rains near trees, leaves may fall with the wind and accumulate on the filter holes of the treatment device. Leaves and other impurities are likely to block the filter holes, thereby affecting the fluidity and filtration efficiency of the water. When the leaves are stationary on the filter holes, they hinder the smooth passage of water, causing the water level to rise and water accumulation. In addition, poor water flow also increases the difficulty of subsequent maintenance. The filter needs to be cleaned manually regularly, which increases maintenance costs and human resource consumption. If not handled in time, these blockages will not only lead to obstructed rainwater discharge, but may also cause equipment damage and more serious environmental impacts. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides an assembled surface source pollution treatment device, which has the advantage of clearing the filter holes in the treatment device, thereby solving the problem of leaves standing still on the filter holes, obstructing the smooth passage of water.

[0011] Preferably, a short plate is fixedly connected to the bottom of the connecting sleeve, a long plate is connected to the short plate via a latch, and a transmission plate is fixedly connected to the bottom of the long plate.

[0012] Preferably, the transmission member comprises a connecting shaft rotatably mounted in the housing, blade groups are mounted on both sides of the connecting shaft, and a plurality of transmission rods corresponding to the transmission plates are fixedly connected to the connecting shaft.

[0013] The flow guide comprises a flow channel 1 obliquely installed on the two side walls of the box body, and a flow channel 2 located below the flow channel 1. The flow channel 1 and the flow channel 2 are staggered and symmetrically distributed, and the water outlet of the flow channel 2 is located obliquely above the blade group.

DETAILED DESCRIPTION

[0034] 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.

[0035] In recent years, with the intensification of global climate change and the increase in the speed of urban development, the problem of non-point source pollution has become increasingly prominent. Non-point source pollution refers to the process in which water flows through the surfaces of urban roads, green spaces, buildings, etc. during rainfall or snowmelt, carrying away dust, oil, chemicals and other pollutants, and eventually flowing into rivers, lakes and other water bodies, seriously affecting water quality and the ecological environment. In order to reduce the negative impact of non-point source pollution, various regions have begun to pay attention to the management and treatment of rainwater and have developed a variety of water purification devices. Among them, the assembled non-point source pollution treatment device, as an effective rainwater filtration solution, has received widespread attention.

[0036] The design concept of the assembled non-point source pollution processor is to enable it to be flexibly applied in different urban environments and terrain conditions through rapid installation and modular construction. The device is usually located at the rainwater inlet and has a built-in high-efficiency filtration system that can capture solid particles and other pollutants suspended in rainwater. However, this type of processor still faces some technical challenges in practical application.

[0037] First, rainwater often contains a large amount of solid matter, such as leaves, soil, and small stones, which can easily flow into the processor with the water during rainfall. Especially in areas with dense trees, leaves falling into the processor may clog the filter holes of the filter device, resulting in obstruction and sedimentation of water flow. This clogging phenomenon not only reduces the filtration efficiency of the processor, but may also cause subsequent equipment failures, resulting in the accumulation of sediment in the system, thereby increasing maintenance frequency and costs.

[0038] Embodiment 1:

[0039] Pollutants carried in rainwater and runoff (such as leaves) will flow directly into the water body, increasing the risk of non-point source pollution and causing serious impacts on the surrounding water environment. In order to solve the above problems, combined with Figure 1-Figure 3 As shown, the present invention provides an assembled non-point source pollution treatment device, including a box 100 installed in a rainwater outlet, a drainage outlet 101 is opened on one side of the box 100, and a filter assembly 200 for filtering impurities in water is arranged in the box 100. By treating rainwater at the source, the pollution to downstream water bodies (such as rivers, lakes, etc.) can be reduced, and the water ecological environment can be protected;

[0040] If the filter assembly 200 is difficult to disassemble and assemble, fault diagnosis and troubleshooting will become difficult, delaying the time for problem solving, and may cause the system to be in a poor operating state for a long time. In order to solve the above problems, the filter assembly 200 includes a shell 201 installed in the box 100, a filter box 207 is placed in the shell 201, a plurality of guide ports are arranged on both sides of the shell 201, and shutters 203 are hinged at the guide ports. A plurality of filter slots 204 are also arranged on both sides of the shell 201. The disassembly design of the filter box 207 and the filter slot 204 allows maintenance personnel to easily remove, clean or replace the filter material, thereby improving the service life and efficiency of the system;

[0041] The box body 100 is also provided with a cleaning assembly 300 for dredging the drain outlet at the bottom of the filter box 207, which can promptly clean up the debris and sediments blocking the drain outlet, ensure smooth water flow, and reduce the risk of water accumulation.

[0042] Specifically, filter sheets 205 are placed on both side walls of the housing 201 , and filter screens 206 are placed on the two filter sheets 205 . The convenient disassembly and assembly design can greatly reduce maintenance time and labor costs, and improve work efficiency.

[0043] Furthermore, the filter box 207 is located above the filter screen 206 , and the filter box 207 does not contact the filter screen 206 .

[0044] The housing 201 is fixedly connected with a frame 202 , which is placed on the outer shell wall. The long plate 305 passes through the slide groove and extends to the bottom of the housing 201 .

[0045] According to the embodiment, the design of multiple diversion ports and louvers 203 allows the water flow to be evenly distributed, avoiding excessive load on a certain part, and helps to improve the overall filtering effect.

[0046] Embodiment 2:

[0047] When the filter holes are covered by leaves, the filter assembly 200 cannot effectively capture other dirt and pollutants, which reduces the overall filtration efficiency and fails to achieve the expected water quality improvement effect. In order to solve the above problem, combined with Figure 4-Figure 6As shown, on the basis of embodiment 1, the cleaning component 300 includes a transmission frame 301 fixedly connected to the middle part of the filter screen 206, and the transmission frame 301 is provided with a transmission frame 302 that can swing left and right, and a plurality of connecting strips 303 corresponding to the drain outlet are fixedly connected to the transmission frame 302, and the connecting strip 303 is composed of two arc-shaped pieces, which can improve the quality of dredging different types of impurities. A transmission member for driving the transmission frame 302 to operate is also provided in the shell 201, and the transmission member drives the transmission frame 302 to swing, and the connecting strip 303 swings with the transmission frame 302, so that the drain outlet at the bottom of the filter box 207 can be dredged, and impurities are prevented from being blocked at the drain outlet and affecting the drainage quality, which is beneficial to improving the drainage efficiency, and can effectively prevent impurities from accumulating at the drain outlet, thereby reducing the risk of poor drainage due to blockage.

[0048] Specifically, a connecting sleeve 310 is hinged on the transmission frame 301, and a connecting column 304 fixedly connected to the transmission frame 302 is inserted on the connecting sleeve 310. The connecting column 304 is inserted into the connecting sleeve 310, so that the transmission frame 302 can be installed. If the transmission frame 302 needs to be disassembled, it is only necessary to pull the connecting column 304 out of the connecting sleeve 310. Through the clear connection point design, the system complexity can be reduced, thereby reducing potential failure points and improving overall reliability.

[0049] Furthermore, a short plate 311 is fixedly connected to the bottom of the connecting sleeve 310, and a long plate 305 is connected to the short plate 311 through a pin 312. A transmission plate 306 is fixedly connected to the bottom of the long plate 305. The long plate 305 can be installed on the short plate 311, which makes it easy to disassemble and assemble the entire assembly later, saving time and labor costs when maintenance, cleaning or replacement is needed.

[0050] According to the embodiment, the water outlet at the bottom of the filter box 207 can be automatically cleaned, which reduces manual intervention and improves the convenience of maintenance.

[0051] Embodiment three:

[0052] Cleaning systems that rely on electric drive may face the risk of equipment failure, such as damage to motors, transmission devices and other components. If a failure occurs, the cleaning work may not be carried out. In order to solve the above problems, combined with Figure 1 , Figure 4 , Figure 5 and Figure 7As shown, on the basis of the second embodiment, the transmission member includes a connecting shaft 307 rotatably installed in the shell 201, and blade groups 309 are mounted on both sides of the connecting shaft 307. The blade groups 309 are flow-shaped, and water contacts the blade groups 309, so that the rotation of the blade groups 309 is more labor-saving. A plurality of transmission rods 308 corresponding to the transmission plates 306 are fixedly connected to the connecting shaft 307. Water flows out from both sides of the shell 201, and then the water flows downward and contacts the blade groups 309 to drive the connecting shaft 307 to rotate. The connecting shaft 307 drives the transmission rod 308 to rotate, and the transmission rod 308 pushes the transmission plate 306 to contact and push the long board 305 thereon to swing, which can drive the transmission frame 302 on the long board 305 to swing, so that the connecting strip 303 on the transmission frame 302 can swing to clear the drain outlet. No electricity is needed, and it can be self-driven in an environment with rainfall or sufficient water flow, which can effectively utilize natural resources and improve the adaptability and sustainability of the system.

[0053] The guide member 313 includes a flow channel 1 3131 obliquely installed on the two side walls of the box body 100, and a flow channel 2 3132 located below the flow channel 1 3131. The flow channel 1 3131 and the flow channel 2 3132 are symmetrically distributed in a staggered manner. The water outlet of the flow channel 2 3132 is located obliquely above the blade group 309. The water in the shell 201 is discharged from both sides, and then the water first falls into the flow channel 1 3131, and then flows from the flow channel 1 3131 into the flow channel 2 3132. The water flows from the water outlet of the flow channel 2 3132 to the blade group 309, and a force is applied to the blade group 309 to rotate it. By increasing the flow distance of the water, the force of the water rushing to the blade group 309 is increased, and then the rotational force of the blade group 309 is increased, so that the connecting strip 303 on the transmission frame 302 swings more strongly, which is beneficial to improving the dredging quality of the filter box 207.

[0054] A plurality of load-bearing blocks are fixedly connected to the two side walls of the box body 100, and a spring 3133 is fixedly connected between the load-bearing blocks and the second flow channel 3132. The bottom of the first flow channel 3131 is fixedly connected to an L-shaped plate 3134 which is slidably connected to the second flow channel 3132. Due to the provision of the L-shaped plate 3134, according to the Bernoulli principle, the water flowing in the second flow channel 3132 forms high and low water levels. The water at a high water level can generate a higher pressure, thereby increasing the force of the water flowing out of the second flow channel 3132, and can further increase the rotational force generated by the water on the blade group 309, which can ensure that the water flow is stable even when the water flow is small. The swing amplitude of the connecting bar 303 on the transmission frame 302 and the setting of the spring 3133, the greater the water flow, the more water volume, the larger the distance between the inner bottom wall of the second flow channel 3132 and the L-shaped plate 3134 is, which can increase the outflow of water. Conversely, the smaller the water flow, the less water volume. The spring 3133 pushes the second flow channel 3132 to reduce the distance between it and the L-shaped plate 3134, so that the position of the L-shaped plate 3134 can be adjusted according to different water flow rates, ensuring that different water volumes can be discharged normally while also applying a rotational force to the blade group 309.

[0055] Through the above embodiment, it can be known that the staff first puts the shell 201 into the box 100, and at the same time inserts the long board 305 into the shell 201 through the slide slot, then puts the filter sheet 205 into both sides of the shell 201, and then installs the long board 305 on the short board 311 through the latch 312, and then places the filter screen 206 on the two filter sheets 205, and then inserts the connecting column 304 into the connecting sleeve 310, and then puts the filter and into the shell 201. When it rains, the water The water flows into the box 100, then passes through the filter box 207 and the filter screen 206, and flows out from both sides of the shell 201. Then the water flows downward and contacts the blade group 309 to drive the connecting shaft 307 to rotate, and the connecting shaft 307 drives the transmission rod 308 to rotate, and the transmission rod 308 pushes the transmission sheet 306 to contact and push the long plate 305 thereon to swing, thereby driving the transmission frame 302 on the long plate 305 to swing, so that the connecting strip 303 on the transmission frame 302 can swing to clear the drain outlet.
