Description

Technical Field

[0001] The invention belongs to the technical field of sewer pipe network protection, and in particular relates to a water accumulation prevention regulating and dredging device for a sewer pipe network. Background Art

[0002] The sewer network is an indispensable and complex component of urban infrastructure. It is mainly composed of sewage pipes, sewer inspection wells, grease traps, sewage treatment facilities, etc. It is responsible for collecting, transporting and treating various wastewater generated in the city, including domestic sewage, industrial wastewater and rainwater sewer networks, which is crucial to protecting people's health and environmental hygiene.

[0003] At present, due to inadequate management and maintenance of municipal drainage systems in many cities, sewer inspection wells are prone to damage and serious siltation. Once sewer inspection wells are blocked or silted, a lot of manpower and financial resources will be spent, affecting the quality of life of residents.

[0004] At present, in the design of existing sewer inspection wells, a water inlet is provided on the manhole cover to facilitate the inflow of rainwater. However, in the case of frequent heavy rains or the water inlet is blocked by debris, rainwater is easily accumulated around the well body, causing inconvenience to vehicle traffic and pedestrian safety. The current measures taken, such as manually lifting the manhole cover or clearing the obstruction of the water inlet to remove the accumulated water, are not only inefficient and labor-intensive, but also have certain safety hazards, and it is difficult to fundamentally solve the problems of water accumulation and siltation. Therefore, it is necessary to explore more efficient, safe and lasting solutions to meet this challenge. Therefore, based on the above problems, we designed a water-proof regulating and dredging device for sewer pipe networks. Summary of the invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a device for regulating and dredging the sewer pipe network to prevent water accumulation, which solves the problem that the existing dredging devices have low cleaning efficiency and safety and are difficult to fundamentally solve the technical problems of water accumulation and siltation.

[0006] To achieve the above-mentioned purpose, according to an embodiment of the first aspect of the present invention, a device for preventing water accumulation, regulating and dredging for a sewer pipe network is provided, comprising: A protective manhole cover is arranged at the wellhead of the sewer, and a garbage blocking filter is arranged on the bottom surface of the protective manhole cover; Adjust the lifting mechanism to adjust the extension height of the garbage isolation filter; A kit is arranged on the garbage isolation filter, and the kit includes a mounting ring seat mounted on the lower end of the outside of the garbage isolation filter, and a rubber ring mounted on the outside of the mounting ring seat and in contact with the inner wall of the wellhead of the sewer. A garbage collection groove is opened on the surface of the mounting ring seat, and the cross-sectional shape of the garbage collection groove is an inverted trapezoid.

[0007] A further improvement is that the adjustable lifting mechanism includes a pair of bases vertically connected to the outer side of the sewer, a limiting rod arranged in the port of each base, a lifting seat sleeved on the limiting rod, a suspension rod arranged between the lifting seats, and a suspension column arranged on the protective manhole cover and connected to the top and the end of the suspension rod. A lifting adjustment cylinder is vertically connected to the outer top surface of each base, and the rod body of the lifting adjustment cylinder extends into the base and is connected to the surface of the lifting seat.

[0008] A further improvement is that there is a gap between the outer edge of the garbage collection groove and the inner wall of the wellhead of the sewer, and the inner edge fits with the outer wall surface of the garbage barrier filter.

[0009] A further improvement is that it also includes a cleaning mechanism, which includes a pair of lifting rods movably inserted into the protective manhole cover and an annular suction hood arranged below the inner wall of the pair of lifting rods and sleeved on the outside of the garbage blocking filter. A vertical suction chamber is arranged in each of the lifting rods, and connecting ports are arranged at the upper and lower ends of each suction chamber. A corrugated cleaning pipe is connected to the connecting port above each suction chamber, and a pair of negative pressure interfaces are arranged on the edge of the outer wall of the annular suction hood, and each negative pressure interface is respectively connected to the connecting port below each suction chamber.

[0010] A further improvement is that a cleaning box is provided at the top of the outer wall of the protective manhole cover, a connected negative pressure zone and a barrier zone are provided in the cleaning box, a high-power negative pressure pump is provided in the negative pressure zone, a barrier cleaning filter element is provided in the barrier zone, and a cleaning port is provided on the cleaning box, which is connected to each corrugated cleaning pipe.

[0011] A further improvement is that the cleaning mechanism also includes a linkage device for driving a pair of lifting rods to lift and lower in a linked manner, the linkage device including a lifting rack arranged on the inner wall surface of each lifting rod, a base plate is arranged on the top surface of the protective manhole cover at a position corresponding to each lifting rack, a linkage gear is rotatably arranged on the same side of each base plate, each of the linkage gears is respectively meshed and connected with each lifting rack, U-shaped connecting pipes are connected on both sides of the suspension rod, and staggered piston push rods 1 and 2 are respectively arranged at both ends of each U-shaped connecting pipe, the bottom end of each piston push rod 1 is connected to the surface of the protective manhole cover, and the other end of each piston push rod 2 is respectively connected to the top surface of each lifting rack, and the side of each U-shaped connecting pipe is connected with an electromagnetic valve.

[0012] A further improvement is that a swing rod is provided on each of the linkage gears, and a suspension rope is provided at the end of each swing rod. A pendulum and a pulley are rotated on both sides of the bottom surface of the protective manhole cover. Each suspension rope passes through the protective manhole cover and is placed on the pulley and is connected to each pendulum accordingly. The initial position of the pendulum is in contact with the inner wall surface of the garbage barrier filter.

[0013] A further improvement is that a groove is provided through the protective manhole cover for each lifting rod to slide and rise and fall.

[0014] A further improvement is that a monitoring component is additionally provided, which includes a mounting block connected to the side of the base, an alarm flashing light arranged on the top surface of the mounting block, and a laser ranging sensor switch on the side, wherein the detection head of the laser ranging sensor switch faces vertically downward.

[0015] Compared with the prior art, the present invention has the following beneficial effects: (1) The present invention utilizes the driving mechanism of the lifting and adjusting cylinder to pull the lifting seat inside the base and the hanging rod and protective manhole cover connected thereto to rise synchronously, exposing the garbage barrier filter, so that the sewage can flow smoothly into the wellhead of the sewer, and after being filtered by the garbage barrier filter, the sewage continues to flow into the well body and subsequent drainage pipelines. In this process, large impurities in the sewage are effectively guided to the garbage collection ditch for centralized collection, while floating objects are effectively intercepted by the garbage barrier filter, thereby preventing debris from entering the drainage system and causing blockage, greatly reducing the burden of subsequent cleaning work. This design fundamentally solves the problems of water accumulation and siltation, ensuring the unobstructed flow of the drainage system; (2) When encountering heavy rainfall, the present invention uses the detection element of the laser ranging sensor switch to accurately capture water level information at a preset frequency. Once the water level rises, the alarm flashing light is triggered to light up, effectively alerting passers-by and construction workers, significantly improving the safety of on-site facilities. At the same time, these real-time collected water level data are quickly transmitted to the central control room via cables. The control room immediately responds by operating the lifting adjustment cylinder to pull the lifting seat in the base and the suspension rod and protective manhole cover on it to continue to rise to adapt to the needs of rainwater discharge of different intensities, demonstrating a high degree of flexibility and response capabilities.

[0016] (3) After the solenoid valve is closed, the linkage mechanism designed in the present invention first triggers the smooth sliding of a pair of piston push rods 1 in their respective U-shaped connecting tubes when the lifting and adjusting cylinder is started to lift the protective manhole cover. This action in turn causes the piston push rod 2 to move downward under the push of air pressure, thereby driving a pair of lifting racks to perform the lifting action and simultaneously driving the linkage gear to rotate in the positive direction. As each linkage gear rotates, the swing rod is activated and tilts upward, and the pendulum is pulled to a specific angle by the suspension rope. When the lifting and adjusting cylinder is operated in the reverse direction to lower the protective manhole cover, the linkage gear and the swing rod rotate in the opposite direction. At this time, the pendulum swings freely due to the loss of pulling force, and finally hits the inner wall of the barrier cleaning filter element. Under the synergistic effect of this process, the garbage attached to the garbage barrier filter is effectively detached under the action of vibration and falls into the garbage collection ditch below, avoiding the attachment of garbage to cause inconvenience to subsequent cleaning personnel; (4) The present invention creates a significant negative pressure environment by starting a high-power negative pressure pump. This negative pressure effect is enhanced as the annular suction hood moves vertically, effectively adsorbing and removing fine garbage particles remaining on the surface of the garbage barrier filter, thereby ensuring efficient cleaning and continuous operation of the filter. When the annular suction hood drops to the lowest position, the negative pressure not only continues to act on the garbage barrier filter, but also strongly sucks the garbage in the garbage collection groove through each annular suction hood and the suction cavity inside it. The sucked garbage is then guided by multiple corrugated cleaning tubes and cleaning ports, and finally deposited on the barrier cleaning filter element in the barrier area, realizing a unified and automated garbage cleaning process. This process not only improves operating efficiency and ensures operational safety, but also significantly reduces the need for manual intervention through a long-lasting and effective filtering mechanism.

DETAILED DESCRIPTION

[0019] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than 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.

[0020] Example 1

[0021] like Figure 1 and Figure 2 As shown, a device for preventing water accumulation, regulating and dredging for a sewer pipe network comprises: A protective manhole cover 3 is arranged at the wellhead of the sewer well 1, and a garbage blocking filter 31 is arranged on the bottom surface of the protective manhole cover 3. The garbage blocking filter 31 is used to block garbage to prevent garbage from entering the sewer well 1 and causing blockage of the sewer pipe network; The kit 4 is arranged on the garbage barrier filter 31. The kit 4 comprises a mounting ring seat 401 which is sleeved on the lower end of the outer portion of the garbage barrier filter 31, and a rubber ring 402 which is sleeved on the outer portion of the mounting ring seat 401 and contacts the inner wall of the wellhead of the sewer 1. The rubber ring 402 is used for sealing. A garbage collecting groove 403 is provided on the surface of the mounting ring seat 401. The cross-sectional shape of the garbage collecting groove 403 is an inverted trapezoid. There is a gap between the outer ring edge of the garbage collecting groove 403 and the inner wall of the wellhead of the sewer 1. The inner ring edge fits the outer wall of the garbage barrier filter 31. During the drainage process, large impurities in the sewage are effectively guided to the garbage collecting groove 403 for centralized collection, while floating objects are effectively intercepted by the garbage barrier filter 31, thereby preventing debris from entering the drainage system and causing blockage, greatly reducing the burden of subsequent cleaning work. like Figure 1 and Figure 2 As shown, the implementation also includes: the regulating lifting mechanism 2 includes a pair of bases 21 vertically connected to the outer side of the sewer well 1, a limit rod 24 arranged in the port of each base 21, a lifting seat 25 sleeved on the limit rod 24, a suspension rod 23 arranged between the lifting seats 25, and a suspension column 201 arranged on the protective manhole cover 3 and connected to the top and the end of the suspension rod 23. The outer top surface of each base 21 is vertically connected with a lifting adjustment cylinder 22, and the rod body of the lifting adjustment cylinder 22 extends into the base 21 and is connected to the surface of the lifting seat 25. By utilizing the driving mechanism of the lifting adjustment cylinder 22, when the lifting seat 25 inside the base 21 is pulled, the suspension rod 23 connected to the lifting seat 25 and the protective manhole cover 3 can be synchronously raised. At this time, the solenoid valve 62 is in an open state to adapt to the requirements of rainwater discharge of different intensities; Example 2

[0022] like Figure 1 As shown, in this embodiment, on the basis of embodiment 1, a monitoring component 5 is additionally provided. The monitoring component 5 includes a mounting block 51 connected to the side of the base 21, an alarm flashing light 53 arranged on the top surface of the mounting block 51, and a laser ranging sensor switch 52 on the side. The detection head of the laser ranging sensor switch 52 is vertically facing downward, which is used to monitor the water level in real time. When encountering heavy rainfall, the detection element of the laser ranging sensor switch 52 accurately captures the water level information at a preset frequency. Once the water level rise is detected, the alarm flashing light 53 is triggered to light up, effectively warning passers-by and construction personnel, and significantly improving the safety of the use of on-site facilities. At the same time, these real-time collected water level data are quickly transmitted to the central control room through cables. The control room immediately responds and uses the operation of the lifting and adjusting cylinder 22 to pull the lifting seat 25 in the base 21 and the suspension rod 23 and the protective manhole cover 3 thereon to continue to rise to meet the needs of rainwater discharge of different intensities.

[0023] Example 3

[0024] like Figures 2 to 5 As shown, on the basis of Example 1 and Example 2, a cleaning mechanism 6 is further included, and the cleaning mechanism 6 includes a pair of lifting rods 61 movably inserted into the protective manhole cover 3 and an annular suction cover 63 arranged below the inner wall surface of the pair of lifting rods 61 and sleeved on the outside of the garbage blocking filter 31. The protective manhole cover 3 is penetrated with a groove 301 for each lifting rod 61 to slide and lift, and a vertical suction chamber 601 is arranged in each lifting rod 61. The upper and lower ends of each suction chamber 601 are provided with a connecting port 602, and the connecting port 602 above each suction chamber 601 is connected to a corrugated cleaning pipe 603. The outer wall edge of the annular suction cover 63 is provided with a pair of negative pressure interfaces 604, and each negative pressure interface 604 is respectively connected to the lower connecting port 602 of each suction chamber 601; The cleaning mechanism 6 also includes a linkage device for driving a pair of lifting rods 61 to lift in linkage, the linkage device includes a lifting rack 64 arranged on the inner wall surface of each lifting rod 61, a base plate 65 is arranged on the top surface of the protective manhole cover 3 at a position corresponding to each lifting rack 64, a linkage gear 66 is rotatably arranged on the same side of each base plate 65, each linkage gear 66 is respectively meshed and connected with each lifting rack 64, a U-shaped connecting pipe 68 is connected to both sides of the suspension rod 23, and a staggered piston push rod 1 681 and a piston push rod 2 682 are respectively arranged at both ends of each U-shaped connecting pipe 68, the bottom end of each piston push rod 1 681 is connected to the surface of the protective manhole cover 3, and the other end of each piston push rod 2 682 is respectively connected to the top surface of each lifting rack 64, and a solenoid valve 62 is connected to the side of each U-shaped connecting pipe 68, and the solenoid valve 62 is used to control the gas discharge and drive the piston push rod 2 682 by the action of air pressure; Specifically, as a preferred implementation scheme, each linkage gear 66 is provided with a swing rod 661, and each swing rod 661 is provided with a suspension rope 662 at its end. A pendulum 663 and a pulley 664 are rotated on both sides of the bottom surface of the protective manhole cover 3, and each suspension rope 662 passes through the protective manhole cover 3 and rests on the pulley 664 and is connected to each pendulum 663. The initial position of the pendulum 663 contacts the inner wall surface of the garbage isolation filter 31. Through the designed linkage mechanism, after the solenoid valve 62 is closed, when the lifting and adjusting cylinder 22 is started to lift the protective manhole cover 3, the first thing that is triggered is the smooth sliding of a pair of piston push rods 1 681 in their respective U-shaped connecting pipes 68. This action then causes the piston push rod 2 682 to move downward under the push of air pressure, thereby driving a pair of lifting racks 64 to perform the lifting action, and synchronously driving the linkage gear 66 to rotate forward. As each linkage gear 66 rotates, the swing rod 661 is activated and tilted upward, and the pendulum 663 is pulled to a specific angle through the suspension rope 662. When the lifting and adjusting cylinder 22 is reversed to lower the protective manhole cover 3, the linkage gear 66 and the swing rod 661 rotate in the opposite direction. At this time, the pendulum 663 swings freely due to the loss of tension, and finally hits the inner wall of the isolation cleaning filter element 674. Under the synergistic effect of this process, the garbage attached to the garbage isolation filter 31 is effectively detached under the action of vibration and falls into the garbage collection groove 403 below, avoiding the attachment of garbage to the subsequent cleaning personnel. Inconvenience, reducing the labor burden of the cleaning personnel; Specifically, as a preferred embodiment, a cleaning box 67 is provided at the top of the outer wall of the protective manhole cover 3, and a connected negative pressure area 671 and a barrier area 672 are provided in the cleaning box 67, a high-power negative pressure pump 673 is provided in the negative pressure area 671, and a barrier cleaning filter element 674 is provided in the barrier area 672. A cleaning port 675 is provided on the cleaning box 67, and the cleaning port 675 is connected to each corrugated cleaning pipe 603, and a negative pressure environment is generated by starting the high-power negative pressure pump 673. This negative pressure effect is enhanced with the vertical movement of the annular suction cover 63, effectively adsorbing and removing the fine garbage particles remaining on the surface of the garbage barrier filter 31, thereby ensuring the efficient cleaning and continuous operation of the filter; when the annular suction cover 63 drops to the lowest position, the negative pressure not only continues to act on the garbage barrier filter 31, but also strongly sucks the garbage in the garbage collection groove 403 through each annular suction cover 63 and the suction cavity 601 inside it. The sucked garbage is then guided by a plurality of corrugated cleaning pipes 603 and cleaning ports 675, and finally deposited on the barrier cleaning filter element 674 in the barrier area 672, thus realizing a unified and automated garbage cleaning process; like Figures 1 to 5 As shown, in this embodiment, it is also necessary to explain that the application document sets the laser distance sensing switch 52 in advance, and a power box is equipped on the base 21 to supply power to each device. In addition, it should be noted that this application document only improves the existing dredging device for the sewer inspection well, which has low cleaning efficiency and safety, and is difficult to fundamentally solve the shortcomings of water accumulation and siltation, and does not involve improvements in other aspects; the working principle of the anti-water accumulation regulating dredging device for the sewer pipe network is introduced as follows: The present invention installs the dredging device on site, and realizes that during drainage operations, the driving mechanism of a pair of lifting and adjusting cylinders 22 is used to pull the lifting seat 25 inside the base 21 and the hanging rod 23 and the protective manhole cover 3 connected thereto to rise synchronously, so that after exposing the garbage barrier filter 31, the sewage can flow smoothly into the wellhead of the sewer well 1, and after being filtered by the garbage barrier filter 31, the sewage continues to flow into the well body and subsequent drainage pipelines. In this process, large impurities in the sewage are effectively guided to the garbage collection groove 403 for centralized collection, while floating objects are effectively intercepted by the garbage barrier filter 31, thereby preventing debris from entering the drainage system and causing blockage, greatly reducing the burden of subsequent cleaning work. This design fundamentally solves the problems of water accumulation and siltation, and ensures the unobstructed flow of the drainage system; When encountering heavy rainfall, the detection element of the laser ranging sensor switch 52 accurately captures the water level information at a preset frequency. Once the water level rises, the alarm flashing light 53 is triggered to light up, effectively alerting passers-by and construction workers, significantly improving the safety of on-site facilities. At the same time, these real-time collected water level data are quickly transmitted to the central control room via cables. The control room immediately responds and uses the operation of the lifting adjustment cylinder 22 to pull the lifting seat 25 in the base 21 and the suspension rod 23 and protective manhole cover 3 thereon to continue to rise, so as to adapt to the needs of rainwater discharge of different intensities, showing a high degree of flexibility and response capabilities.

[0025] After the equipment is continuously running, when the lifting and adjusting cylinder 22 is started to lift the protective manhole cover 3 after the electromagnetic valve 62 is closed through the designed linkage mechanism, the first thing triggered is the smooth sliding of a pair of piston push rods 1 681 in their respective U-shaped connecting pipes 68. This action then causes the piston push rods 2 682 to move downward under the push of air pressure, thereby driving a pair of lifting racks 64 to perform lifting actions, and synchronously driving the linkage gear 66 to rotate forward. As each linkage gear 66 rotates, the swing rod 661 is activated and tilted upward, and the pendulum 663 is pulled to a specific angle through the suspension rope 662.

[0026] When the lifting and adjusting cylinder 22 is operated in the reverse direction to lower the protective manhole cover 3, the linkage gear 66 and the swing rod 661 rotate in the reverse direction. At this time, the pendulum 663 swings freely due to the loss of tension, and finally hits the inner wall of the isolation cleaning filter element 674. Under the synergistic effect of this process, the garbage attached to the garbage isolation filter 31 is effectively separated under the action of vibration and falls into the garbage collection groove 403 below, so as to avoid the attachment of garbage to cause inconvenience to the subsequent cleaning personnel; At the same time, during the entire lifting process of the protective manhole cover 3, the lifting rod 61 maintains a stable sliding track in the groove 301, and the activation of the high-power negative pressure pump 673 creates a significant negative pressure environment. This negative pressure effect is enhanced as the annular suction cover 63 moves vertically, effectively absorbing and removing fine garbage particles remaining on the surface of the garbage isolation filter 31, thereby ensuring efficient cleaning and continuous operation of the filter.

[0027] When the annular suction hood 63 drops to the lowest position, the negative pressure not only continues to act on the garbage isolation filter 31, but also strongly sucks the garbage in the garbage collection groove 403 through each annular suction hood 63 and the suction chamber 601 inside. The sucked garbage is then guided by multiple corrugated cleaning pipes 603 and cleaning ports 675, and finally deposited on the isolation cleaning filter element 674 in the isolation area 672, realizing a unified and automated garbage cleaning process. This process not only improves operating efficiency and ensures operational safety, but also significantly reduces the need for manual intervention through a long-lasting and effective filtering mechanism.

[0028] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
