Description

Technical Field

[0001] The present invention relates to the field of municipal drainage, and more particularly to a municipal drainage treatment device. Background Art

[0002] Rainwater drainage is a crucial component of urban municipal drainage systems, primarily achieved through rainwater purification and drainage systems. These systems are responsible for transporting collected rainwater to urban or natural water bodies, such as rivers, lakes, or oceans, to prevent urban waterlogging and flooding.

[0003] The municipal drainage system is mainly composed of drainage pipes and manhole covers, which are used to collect and preliminarily filter rainwater from surface runoff. At present, in order to improve the efficiency of rainwater discharge and reduce the impact on the environment, commonly used rainwater inlet filtration devices include vertical grate rainwater grates, manhole covers, drainage wells, etc., which are staggered and used in combination. Among them, vertical grate rainwater grates play a key role in drainage purification. They mainly include brackets for installation on the curbs on both sides of the street edge or on the drainage outlets at the intersection of green belts and roads, grid plates installed on the brackets to intercept larger debris (such as leaves, tree trunks, stones, etc.), and safety locks or anti-theft devices to prevent theft or accidental displacement; when it rains, rainwater enters the drainage pipe from the drain outlet and gathers in the drainage well. The grid plates purify and intercept debris such as leaves and plastic bags at the drain outlet to prevent debris from clogging the drainage pipe and ensure drainage. While the water system is unblocked, the rainwater is preliminarily purified and filtered to reduce the pollution of urban water bodies. However, the grille plates in the existing vertical grate rainwater grates are usually installed on the edge of the curb or on the side where the green belt and the road meet, and only one side is used to intercept garbage. When it rains heavily, the rainwater is relatively turbulent and mixed with a large amount of urban road garbage. The garbage accumulates on one side of the grille plate, and the pressure exerted by the heavy rain is relatively large, which will cause blockage at the drain outlet, resulting in a significant reduction in the efficiency of rainwater drainage, causing traffic congestion such as waterlogging on the road and difficulty for vehicles to pass.

[0004] Similarly, when garbage accumulates above the drain manhole cover, objects such as plastic bags can easily clog the drainage holes of the drain manhole cover, thereby affecting drainage efficiency and causing water accumulation. Summary of the Invention

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0020] Reference Figures 1 to 6 As shown, to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a municipal drainage treatment device, comprising an edge drainage system 1, a manhole cover drainage system 2 and a central control system 3, wherein the edge drainage system 1 and the manhole cover drainage system 2 are respectively connected to the central control system 3; The edge drainage system 1 includes a mounting frame 11, a filter frame 12, a drive component 13, and a first flow meter 14. A drainage channel is provided within the mounting frame 11. The first flow meter 14 is disposed within the drainage channel and is used to detect the flow of rainwater in the drainage channel and send a flow detection signal to the central control system 3. The filter frame 12 is movable and connected to the drainage channel via the drive component 13. The manhole cover drainage system 2 includes a mounting base 21, a drainage manhole cover 22, a lifting component 23, and a second flow meter 24. The second flow meter 24 is disposed on the mounting base 21 and is used to detect the flow of rainwater passing through the mounting base 21 and send a flow detection signal to the central control system 3. The drainage manhole cover 22 is connected to the mounting base 21 by the lifting component 23. A first cleaning structure 4 is provided on the side of the drainage manhole cover 22 facing the mounting frame 11. The first cleaning structure 4 is used to clean garbage on one side of the filter frame 12. A second cleaning structure 5 is provided at the lower end of the filtering frame 12, and the second cleaning structure 5 is used to clean the garbage on the drain manhole cover 22.

[0021] In the design of the present invention, when there is continuous moderate rain or sudden heavy rain or rainstorm, the water accumulation speed on the ground increases. At this time, the strong wind and heavy rain will carry garbage such as fallen leaves and plastic bags and accumulate at the drainage holes 221 of the drain manhole cover 22 and the water inlet side of the filtering frame 12, resulting in a lower drainage efficiency, more water accumulation on the ground, and affecting normal passage.

[0022] At this time, the rainwater volume in the drain manhole cover 22 and the filtering frame 12 detected by the corresponding first flowmeter 14 or second flowmeter 24 will decrease significantly, then it is determined that the drain manhole cover 22 or the filtering frame 12 at the corresponding position is blocked by garbage. In order to avoid affecting the drainage efficiency, at this time, the first cleaning structure 4 and the second cleaning structure 5 are used to remove the garbage on the drain manhole cover 22 and the filtering frame 12, so as to ensure the stability of the drainage efficiency.

[0023] The present invention is further provided that: the first cleaning structure 4 includes a cleaning plate 41 provided at the lower end of the drain manhole cover 22. There are three groups of cleaning plates 41, and they are arranged in a "U" - shaped structure, and together with the drain manhole cover 22, they enclose a cleaning space 42 for the filtering frame 12 to pass through. When the driving component 13 pushes the filtering frame 12 into the cleaning space 42, the side surface of the filtering frame 12 abuts against the cleaning plate 41.

[0024] Preferably, the drain manhole cover 22 is arranged in a square - cover structure, which can facilitate the arrangement of the cleaning plate 41. When the drain manhole cover 22 rises, it can reduce the gap between the cleaning plate 41 and the ground. Thus, when the filtering frame 12 is inserted into the cleaning space 42, when the accumulated water on both sides converges through the side surface of the filtering frame 12, the accumulated water will flow to the drainage channel and the water inlet side of the filtering frame 12 respectively. When impacting the water inlet side of the filtering frame 12, it can impact the garbage originally stuck at the water inlet side with the water in the reverse direction and push it into the drain manhole cover 22, thus completing the cleaning operation of the filtering frame 12.

[0025] The present invention is further provided that: the second cleaning structure 5 includes a cleaning rod 51 provided at the lower end of the filtering frame 12. A sliding groove is provided in the filtering frame 12, and the cleaning rod 51 is slidably connected to the sliding groove through a spring; There are multiple groups of cleaning rods 51, and they are arranged in one - to - one correspondence with the drainage holes 221 on the drain manhole cover 22.

[0026] Guide inclined surfaces 52 are provided on both sides of the cleaning rod 51.

[0027] Multiple groups of drainage holes 221 are provided on the drain manhole cover 22, and the arrangement direction of the multiple groups of drainage holes 221 is perpendicular to the moving direction of the filtering frame 12.

[0028] This structural design means that when garbage accumulates in the drain cover 22, it will clog the drain hole 221, thereby reducing the drainage efficiency of the drain cover 22. At this time, the filter frame 12 is moved out by the driving component 13. When the cleaning rod 51 on the filter frame 12 moves to the drain hole 221, the cleaning rod 51, under the action of a spring, extends downward, puncturing or pushing a garbage bag (for example) into the drain hole 221. The filter frame 12 is then moved back and forth, completely breaking up or squeezing the garbage bag into the drain hole 221, thereby restoring the drainage efficiency of the drain cover 22.

[0029] The design of the guiding slope 52 enables the cleaning rod 51 to retract when the cleaning rod 51 moves out of the drainage hole 221 through the contact between the guiding slope 52 and the side wall of the drainage hole 221 .

[0030] Since the arrangement direction of the drainage holes 221 is perpendicular to the moving direction of the filter frame 12 , when the filter frame 12 moves, the drainage holes 221 at multiple positions can be cleaned simultaneously, thereby improving the cleaning efficiency.

[0031] The present invention is further configured as follows: the driving component 13 and the lifting component 23 each include a control motor, a control rod, a bearing and a moving rod, and the control motor is connected to the control rod to drive the control rod to rotate; The moving rod is connected to the control rod through a bearing.

[0032] The driving component 13 and the lifting component 23 adopt various structures. Taking the electric telescopic rod structure as an example, it has the advantages of precise movement and convenient control.

[0033] The present invention is further configured as follows: the central control system 3 includes a receiving module 31, a processing module 32, a recording module 33, a communication module 34 and a control module 35; The receiving module 31 is connected to the first flow meter 14 and the second flow meter 24 respectively, and is used to receive the flow data Z1 in the drainage channel and the flow data Q1 in the mounting seat 21; The recording module 33 is connected to the cloud information through the communication module 34, and the cloud information includes the current rainfall data W1; The processing module 32 is used to generate a flow data range N1 according to the rainfall data W1, and compare the flow data Q1 and the flow data Z1 with the flow data range N1 to generate a control signal; The control module 35 controls the opening and closing of the lifting component 23 and / or the driving component 13 according to the control signal.

[0034] The cloud records real-time local meteorological data. The rainfall data W1 can be inferred based on the current rainfall. The normal water volume in the drainage manhole cover 22 and the drainage channel can be inferred based on the rainfall data W1. The water volume is recorded as the flow data range N1.

[0035] When the real-time flow data Q1 and flow data Z1 are compared with the flow data range and are both smaller than the flow data range N1, it is determined that the drainage manhole cover 22 or the filter frame 12 is blocked. At this time, the control module 35 will generate a control signal and remotely send it to the lifting component 23 and the driving component 13, allowing them to perform the corresponding processing according to the set program.

[0036] The specific processing process includes the following steps: The specific operation steps of the processing module 32 include: S1, obtain the rainfall data W1 in the recording module 33 and generate the flow data range N1; S2, the flow data range N1 includes the rainfall data Z2 of the drainage channel and the rainfall data Q2 in the mounting seat 21; S3, compare the flow data Z1 with the rainfall data Z2, and generate a control signal L1 when Z1 is less than Z2; S4, comparing the flow data Q1 with the rainfall data Q2, and generating a control signal L2 when Q1 is less than Q2.

[0037] The present invention is further configured such that the cleaning step of the edge drainage system 1 includes: M1, the control module 35 controls the drainage manhole cover 22 to rise through the lifting component 23 according to the control signal L1; M2 , the control module 35 controls the filter frame 12 to move out by a distance P1 through the driving component 13 according to the control signal L1 until it is inserted into the first cleaning structure 4 .

[0038] The present invention is further configured as follows: the cleaning steps of the manhole cover drainage system 2 include: X1, the control module 35 moves the filter frame 12 out of the movement distance P2 through the driving component 13 according to the control signal L2, and cleans the garbage on the drainage manhole cover 22 through the second cleaning structure 5; The P2 movement amount is greater than the P1 movement amount. This design of the movement amount can ensure that the two movement distances are controllable.

[0039] The above are merely preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions based on the principles of the present invention are within the scope of protection of the present invention. It should be noted that improvements and modifications that do not depart from the principles of the present invention are within the scope of protection of the present invention.
