Description

Technical Field

[0001] The present application belongs to the technical field of urban municipal pipeline operation and maintenance, and in particular relates to a floating garbage collection device. Background Art

[0002] The urban drainage pipeline network is an important part of urban infrastructure. It is mainly used to collect, transport and treat sewage and rainwater in the city to ensure urban environmental sanitation and the quality of life of residents. For example, the urban drainage pipeline network can quickly and effectively discharge sewage and rainwater out of the urban area through the underground pipeline system. Especially in the rainy season, the drainage pipeline network can quickly drain rainwater and reduce the risk of urban waterlogging. In addition, the urban drainage pipeline network can also treat urban sewage to meet the standards through the sewage treatment system before discharging it, reducing pollution to the natural environment. However, since the urban drainage pipeline network is deeply buried underground and the on-site working conditions are complex, if the operation and maintenance are improper, it is easy to affect the normal and healthy operation of the drainage pipeline network, and increase the risks of urban waterlogging, combined system overflow pollution, etc.

[0003] Since there are a lot of impurities and garbage in the water transported by municipal pipelines, it will not only affect the treatment efficiency of the sewage treatment plant, but also have a negative impact on the measurement results of water quantity and quality monitoring equipment. At this time, the traditional screen pollution interception technology has the problem of too much resistance. If the sewage pipe is not cleared in time, it may cause siltation, blockage and even sewage overflow. It cannot be placed in the traditional sewage inspection well, and can only be carried out at key nodes such as pumping stations by expanding the screen room and using automatic mechanical slag removal. This has led to the inability of traditional pollution interception equipment to match the traditional pipeline cleaning work.

[0004] Furthermore, large municipal sewage pipes are mostly designed with sewage inspection wells. The inspection well manhole is located at one end of the well chamber and is often not aligned with the main road of the municipal pipe network, which further increases the difficulty of garbage removal. Therefore, how to effectively remove flexible floating garbage such as garbage bags in the water without affecting the normal drainage of the pipe network has become a technical problem that needs to be solved urgently. Summary of the invention

[0005] The present application provides a floating garbage collection device, which is used to solve the technical problem of how to effectively remove flexible floating garbage in a water body without affecting the normal drainage of a pipe network.

[0015] In an implementation of the first aspect, support plates are provided on both sides of the sewage diversion channel; the support plates are connected to the diversion dam by a hinge, and the intersection is located between the above-water diversion part and the underwater diversion part; when the support plates are subjected to a large flow in the pipes on both sides of the sewage inspection well, the diversion dam is changed from an upright state to a horizontal state to reduce water flow resistance.

[0036] The following describes the embodiments of the present application through specific examples, and those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification.

In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0038] In addition, in this application, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0039] In order to at least solve the engineering problems involved in the technical background, a floating garbage collection device is provided in an embodiment of the present application, which can effectively remove flexible floating garbage in the water body, improve sewage treatment efficiency, and ensure the normal operation of monitoring equipment such as water quantity and water quality in sewage inspection wells.

[0040] See also Figures 1 to 3 As shown, a floating garbage collection device A provided by an embodiment of the present application is arranged in a sewage inspection well B, and a sewage water guide groove B1 is arranged in the sewage inspection well B, and the two ends are connected to the drainage pipe B2. That is, urban sewage will flow into the sewage inspection well B from the upstream along the drainage pipe B2, and continue to flow to the downstream drainage pipe B2 through the sewage water guide groove B1. Among them, when the sewage passes through the sewage inspection well B, the floating garbage collection device A will collect the flexible floating garbage such as garbage bags in the water body of the sewage inspection well B to avoid the accumulation of a large amount of garbage in the drainage pipe B2. At the same time, it also avoids the water quantity and water quality monitoring equipment located downstream of the sewage inspection well B from being disturbed by the hanging of garbage, ensuring the normal operation of the monitoring equipment.

[0041] For details, please continue to refer to Figures 1 to 3As shown, the floating garbage collection device A includes a diversion dike 1 and a garbage collection area 2.

[0042] The diversion dam 1 is arranged on the sewage water channel B1, so that the floating garbage in the sewage inspection well B flows to one side of the sewage water channel B1. The diversion dam 1 collects garbage in the form of drainage to prevent garbage from accumulating on the mainstream, thereby effectively reducing the impact of garbage collection on the mainstream.

[0043] The garbage collection area 2 is arranged at one side of the sewage diversion channel B1, and the floating garbage flows into the garbage collection area 2 after being guided by the diversion dam 1.

[0044] In some embodiments, the sewage inspection well B is an eccentric well structure. The eccentric well is a specially designed well structure, and its main feature is that the manhole and the center line of the mainstream pipeline do not coincide, that is, there is a certain eccentricity. Therefore, the floating garbage collection device A provided in the present application can be applied to the eccentric well, which sets the garbage collection area 2 on one side of the manhole, and diverts the water flowing through the sewage inspection well B (eccentric well) to the manhole side through the diversion dike 1, so as to collect floating garbage in the water body, and can clean the garbage collection area 2 through the manhole in time.

[0045] For details, please continue to refer to Figures 1 to 3 As shown, the dike 1 includes a first dike 11 and a second dike 12, and there is a front-to-back difference between the first dike 11 and the second dike 12, and there is a certain gap between the first dike 11 and the second dike 12 in the projection perpendicular to the water flow direction, and the total length of the gap is less than 1 / 10 of the flow cross section. As a result, floating garbage can be transferred to the side by the water flow guidance effect, and at the same time, the front-to-back difference between the first dike 11 and the second dike 12 can further reduce the flow resistance of the diversion structure when diverting floating garbage.

[0046] Since there is a front-to-rear difference between the first diversion dike 11 and the second diversion dike 12, when sewage enters the sewage inspection well B along the drainage pipe B2, part of the water will be diverted directly through the second diversion dike 12 and then enter the garbage collection area 2, and part of the water will first be diverted through the first diversion dike 11 and then through the second diversion dike 12 to enter the garbage collection area 2. Due to the segmented diversion, the water flow impact on the diversion dike 1 will be dispersed, thus avoiding the huge water flow impact that will damage the diversion dike 1 when the drainage pipe B2 is full of flow.

[0047] Please refer to Figures 1 to 3 As shown, the diversion dike 1 actually includes an above-water diversion part and an underwater diversion part.

[0048] The underwater guide part is submerged in the water and has a relatively low penetration depth. In some embodiments, the penetration depth of the underwater guide part is 20 to 50 mm.

[0049] There is a certain angle between the underwater guide part and the above-water guide part. In some embodiments, the angle with the intersection point as the focus is preferably set in the range of 160 to 180. This is because if the angle is too small, the underwater guide part will go too deep into the water, thereby increasing the resistance of small flow, while if it is too large, it is not conducive to leveling large flow.

[0050] Among them, the width of the above-water diversion part (perpendicular to the water flow direction) is greater than the underwater diversion width, so that floating garbage on the water surface can be intercepted while minimizing water resistance, and the floating garbage can be diverted to the garbage collection area 2.

[0051] For details, please continue to refer to Figures 1 to 3 As shown, the garbage collection area 2 includes a needle-shaped fixing area 21 and a garbage collection box 22. The needle-shaped fixing area 21 is arranged in front of the garbage collection box 22, and the floating garbage flows through the needle-shaped fixing area 21 and enters the garbage collection box 22. The garbage collection box 22 can collect the garbage missed by the needle-shaped fixing area 21 through the impact of water flow. And because the garbage collection box 22 can face the flow direction, the collection efficiency will be higher.

[0052] For further information, please refer to Figures 1 to 3 As shown, the needle-shaped fixing area 21 is provided with a plurality of fixing needles arranged in sequence; the needle-shaped fixing area 21 hooks the floating garbage in the sewage inspection well through the fixing needles.

[0053] For further information, please refer to Figures 1 to 3 As shown, a leakage hole 221 is provided at the bottom of the garbage collection box 22 and on the side near the sewage water channel; after the drifting garbage enters the garbage collection box 22, the water flows through the leakage hole 22 and continues to flow downstream.

[0054] Since the leakage holes 221 are arranged at the bottom and sides of the garbage collection box 22, when the sewage flows into the garbage collection box 22 due to the diversion of the diversion dike 1, the flexible floating garbage such as plastic bags in the sewage will be collected by the garbage collection box 22, and the sewage will continue to flow downstream through the leakage holes 221. In this way, the normal discharge of sewage is guaranteed, and the floating garbage in the water body can be collected in time, preventing a large amount of floating garbage from accumulating downstream and affecting the normal treatment of sewage.

[0055] For further information, please refer to Figures 1 to 3As shown, a vertical garbage hanging plate 222 is provided at the rear side of the garbage collection box 22 . After the drifting garbage enters the garbage collection box 22 , it is fixed in the vertical garbage hanging plate 222 .

[0056] Specifically, the vertical garbage hanging plate 222 is provided with a plurality of fixed needles pointing to the center line direction of the flow channel, and the heights of the fixed needles decrease gradually from the sewage water guide groove to the outside (one side of the pipe), so that as much collected garbage as possible can be left on the edge.

[0057] Therefore, in the floating garbage collection device provided by the embodiment of the present application, the needle-shaped fixed area 21 is the main garbage collection area, which has a large area and can efficiently collect floating garbage through the fixed needles. The vertical garbage hanging plate 222 is arranged in the garbage collection box 22, and collects the garbage missed by the needle-shaped fixed area 21 through the impact of the water flow, and because it is directly opposite to the flow direction, the collection efficiency of floating garbage is relatively high.

[0058] For further information, please refer to Figures 1 to 3 As shown, a pull rope 3 is provided above the garbage collection box 22, and the garbage collection box 22 is moved up and down by the pull rope 3.

[0059] In order to ensure the normal operation of the urban drainage pipeline network, each sewage inspection well B will have corresponding operation and maintenance personnel to carry out operation and maintenance management, so as to timely inspect and manage the drainage pipeline. Therefore, at regular intervals, the operation and maintenance personnel will timely pull up the garbage collection box 22 in the sewage inspection well B through the pull rope 3, so as to timely clean up the garbage collected in the garbage collection box 22. Afterwards, after the cleaning is completed, the garbage collection box 22 is put back into the sewage inspection well B through the pull rope 3 to continue collecting garbage.

[0060] For further information, please refer to Figures 1 to 3 As shown, the garbage collection device B further includes a positioning member 4, which uses magnetic attraction to enable the garbage collection box 22 to quickly move to the side and automatically move to a designated position through the garbage collection box 22.

[0061] As mentioned above, when the operation and maintenance personnel timely pull up the garbage collection box 22 in the sewage inspection well B through the pull rope 3 and clean up the garbage in the garbage collection box 22, they will put the garbage collection box 22 back into the sewage inspection well B again through the pull rope 3. At this time, during the process of putting it back down, the positioning member 4 can realize the rapid positioning of the garbage collection box 22 to ensure that the garbage collection box 22 can be automatically and quickly put back to the original area.

[0062] Furthermore, as mentioned above, since the vertical garbage hanging plate 222 hooks the garbage through the fixed needle, the tip of the fixed needle can be used to better pierce the floating garbage bag, so that the garbage collection box 22 can reduce the amount of sewage picked up during the lifting process.

[0063] In some embodiments, the positioning member 4 includes a magnetic plate. The magnetic plate uses magnetic attraction to realize the positioning of the object. Correspondingly, a magnetic member is provided on the rear side of the garbage collection box 22. By providing a positioning member 4 on the sewage inspection well B and a magnetic member on the garbage collection box 22, the garbage collection box 22 can be automatically aligned and fixed in a designated position by magnetic attraction during the downward movement, ensuring that when the operation and maintenance personnel cannot see the situation under the sewage inspection well B, they can quickly move the garbage collection box 22 to the underground position only by the pull rope 3 and magnetic attraction. The operation is simple, the positioning is accurate, and the installation is convenient.

[0064] Please refer to Figures 1 to 3 As shown, in some embodiments, the positioning member 4 can also play a supporting role to support the wall of the sewage inspection well B. Therefore, positioning members 4 are provided on both sides of the sewage water channel B1.

[0065] For further information, please refer to Figures 1 to 3 As shown, support plates B11 are provided on both sides of the sewage water guide channel B1; the support plate B11 is connected to the diversion dike 1 by a hinge, and the intersection is located between the above-water diversion part and the underwater diversion part. When the support plate B11 is subjected to a large flow in the pipes on both sides of the sewage inspection well, the above-water diversion part is impacted by the large water flow, subjected to a large force along the flow velocity direction, and affected by the fulcrum torque, thereby the diversion dike 1 is changed from an upright state to a horizontal state to reduce the water flow resistance.

[0066] As described above, the floating garbage collection device provided in the present application can effectively remove flexible floating garbage such as garbage bags in the water body without affecting the normal drainage of the pipeline network, improve the treatment efficiency of the sewage treatment plant, and ensure the normal operation of monitoring equipment such as water quantity and quality.

[0067] In actual application scenarios, the method of using the garbage collection device provided in this application is as follows: the operation and maintenance personnel put the garbage collection box 22 into the sewage inspection well B by pulling the rope 3, and quickly locate the garbage collection box 22 by the positioning member 4 arranged in the sewage inspection well B, so as to achieve the garbage collection box 22 reaching the designated position. The sewage inspection well B is connected with drainage pipes B2 on both sides. When the sewage is discharged through the drainage pipes B2 and enters the sewage inspection well B, it will flow along the diversion dam 1 to the garbage collection area 2 arranged on one side of the sewage water guide channel B1. At this time, the garbage collection box 22 will collect floating garbage in the water body, and the sewage will continue to swim downstream along the leakage hole 221. In addition, a needle-shaped fixing area 21 is provided in front of the garbage collection box 22, which can mainly collect floating garbage, and some missed garbage will be further collected by the garbage collection box 22, so that the operation and maintenance personnel can timely and regularly pull up the garbage collection box 22 through the pull rope 3 to clean up the garbage collected by the garbage collection box 22, so as to ensure that there is no accumulation and floating of a large amount of garbage in the sewage inspection well B, and ensure the normal operation of the water quantity, water quality and other monitoring equipment in the sewage inspection well B. At the same time, since the garbage in the sewage continues to flow downstream after being collected, it is also ensured that a large amount of garbage will not accumulate in the downstream drainage network, ensuring the normal operation of the drainage network and improving the sewage treatment efficiency downstream.

[0068] The descriptions of the processes or structures corresponding to the above-mentioned figures have different emphases. For parts that are not described in detail in a certain process or structure, please refer to the relevant descriptions of other processes or structures.

[0069] The above embodiments are merely illustrative of the principles and effects of the present application and are not intended to limit the present application. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present application. Therefore, all equivalent modifications or changes made by a person of ordinary skill in the art without departing from the spirit and technical ideas disclosed in the present application shall still be covered by the claims of the present application.
