Technical Field

[0001] This utility model relates to an integrated device for collecting rainwater from manhole covers, and more particularly to an integrated device for collecting rainwater from manhole covers used in the field of manhole covers. Background Technology

[0002] In existing municipal construction, storm and sewage inspection well covers consist of two parts: a ductile iron well cover and a well ring reinforcement underneath the well cover.

[0003] Chinese utility model patent for an integrated anti-displacement manhole cover, patent application number CN202022338994.1, relates to an integrated anti-displacement manhole cover, comprising a manhole cover base and a manhole cover. Its features include: an anti-displacement ring formed by concrete pouring on the upper part of the manhole body, the inner diameter of which matches the outer diameter of the manhole cover base, and the upper surface of which is flush with the road surface; a stable ring formed by cement and gravel covering the outer side of the anti-displacement ring; the manhole cover base is located on the upper part of the manhole body, its inner diameter matching that of the manhole body; the manhole cover is fastened to the base; and an anti-displacement retaining ring is provided on the lower surface of the manhole cover, its outer diameter matching the inner diameter of the base. This design solves the safety hazard problem caused by existing manhole covers easily shifting after installation and exposing the opening.

[0004] When the above-mentioned device is in use, no filter component is installed inside the manhole cover. At this time, rainwater will carry impurities from the road surface into the rainwater cellar, affecting the quality of the rainwater in the cellar. In addition, there is no warning device, and staff need to carry warning railings to warn the surrounding area and reduce the approach of irrelevant people, which has certain shortcomings. Summary of the Invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by this utility model is to perform multi-layer filtration of rainwater and to provide warnings to the surrounding area during the operation.

[0006] To address the aforementioned problems, this utility model provides an integrated device for collecting rainwater from manhole covers, including a manhole cover and further comprising:

[0007] The well ring is reinforced with a hollow cylindrical design, and the well cover is installed on the well ring reinforcement.

[0008] Multiple filter plates are set at equal intervals inside the well ring reinforcement and are matched with the inner diameter of the well ring reinforcement. The pore diameter of the filter holes on the multiple filter plates increases from bottom to top.

[0009] The placement groove is set in a ring shape on the well ring reinforcement;

[0010] The warning ring is slidably connected in the placement slot; the warning ring is a circular ring.

[0011] A long rod is fixedly connected to the warning ring, and one end of the long rod is slidably connected to the well ring reinforcement.

[0012] The filter plate filters impurities from rainwater. When cleaning, the manhole cover is opened, the warning ring is pulled up, and then the filter plate is removed for cleaning.

[0013] In the aforementioned integrated rainwater collection manhole cover device, rainwater is filtered through a filter plate, and a warning ring is used to alert the surrounding area.

[0014] As a further improvement of this application, a tie rod is fixedly connected to the filter plate, which is used to pull the filter plate out of the well ring reinforcement.

[0015] As a further improvement of this application, a groove is provided on the placement slot, and a limit rod is slidably connected in the groove. One set of long rods is provided with a limit hole. By inserting the limit rod into the limit hole, the warning ring after moving upward can be fixed, thereby playing a warning role.

[0016] As a further improvement to this application, a toggle plate that matches the groove is fixedly connected to the limit rod.

[0017] As a further improvement of this application, the warning ring is provided with a pull-up groove for inserting a finger.

[0018] As another improvement of this application, the lifting groove is located within the groove.

[0019] As a further improvement of this application, an electric telescopic rod is installed below the well ring reinforcement. A water baffle plate is fixedly connected to the telescopic end of the electric telescopic rod. A water baffle ring matching the water baffle plate is fixedly connected to the inner wall of the well ring reinforcement. Through the setting of the water baffle plate and the water baffle ring, the filtered water flowing in can be intercepted. A water collection well is set on the side of the well ring reinforcement. A connecting pipe is installed on the water baffle ring of the well ring reinforcement. The connecting pipe is connected to the water collection well.

[0020] As another improvement of this application, a water level sensor is installed inside the water collection well.

[0021] In summary, the multiple filter plates effectively filter impurities of different sizes, reducing impurities in the rainwater cistern below. Furthermore, the warning rings can be raised during operation to alert nearby personnel and reduce the approach of unauthorized individuals. Attached Figure Description

Detailed Implementation

[0030] The following describes one embodiment of this application in detail with reference to the accompanying drawings.

[0031] First implementation method:

[0032] Figures 1-5The diagram shows an integrated rainwater collection manhole cover device, including a manhole cover 1, and further comprising: a manhole ring reinforcement 2, which is a hollow cylindrical structure, with the manhole cover 1 mounted on the manhole ring reinforcement 2; multiple sets of filter plates 301, evenly spaced within the manhole ring reinforcement 2 and matching the inner diameter of the manhole ring reinforcement 2, with the pore diameter of the filter plates 301 increasing progressively from bottom to top; a placement groove 201, annularly positioned on the manhole ring reinforcement 2; a warning ring 401, slidably connected within the placement groove 201, the warning ring 401 being a circular ring with a warning coating applied to both the inner and outer rings; and a long rod 402, fixedly connected to the warning ring 401, with one end of the long rod slidably connected within the manhole ring reinforcement 2; the filter plates 301 filter impurities in the rainwater before subsequent water collection. During cleaning, the manhole cover 1 is opened, the warning ring 401 is pulled up, and then the filter plate 301 is taken out for cleaning. A pull rod 302 is fixedly connected to the filter plate 301. The pull rod 302 is used to pull the filter plate 301 out of the manhole ring reinforcement 2. A groove 202 is provided on the placement groove 201. A limit rod 403 is slidably connected in the groove 202. A set of long rods 402 is provided with a limit hole. By inserting the limit rod 403 into the limit hole, the warning ring 401 after moving upward can be fixed, thereby playing a warning role. A toggle plate 404 that matches the groove 202 is fixedly connected to the limit rod 403. A pull groove 405 for inserting a finger is provided on the warning ring 401. The pull groove 405 is located in the groove 202.

[0033] During rainfall, rainwater enters the manhole ring reinforcement 2 through the manhole cover 1 and flows sequentially through multiple sets of filter plates 301. Because the filter holes of the filter plates 301 increase in diameter from bottom to top, the upper filter plate 301 filters out large particles of impurities first, while the lower filter plate 301 filters out relatively small particles of impurities. This achieves graded filtration of impurities in the rainwater, effectively reducing the amount of impurities entering the rainwater cistern below, improving the quality of rainwater collection, and reducing the difficulty of cleaning impurities in subsequent rainwater treatment.

[0034] In normal operation, the warning ring 401 is circular with a degree between 270 and 300 degrees. The warning ring 401 is stored in the placement slot 201 without affecting the normal appearance of the manhole cover. When it is necessary to work inside the device, the operator opens the manhole cover 1 and pulls the warning ring 401 upward through the lifting slot 405. At this time, the long rod 402 moves upward simultaneously. Then, the limiting rod 403 is inserted into the limiting hole of the long rod 402 through the actuating plate 404 to fix the position of the warning ring 401. Since the warning ring 401 is higher than the manhole ring reinforcement 2 at this time, its inner and outer ring warning coatings can remind the surrounding personnel that work is being carried out here. The circular design makes it easy for the staff to lift the filter plate 301 and take it out. At the same time, the warning ring 401 can reduce the approach of irrelevant personnel and improve the safety of the operation.

[0035] In practical use:

[0036] When it is necessary to clean filter plate 301, the operator arrives at the device location with tools, first confirms that the surrounding environment is safe, and prepares to open manhole cover 1.

[0037] Use appropriate tools, such as a well hook, to open the well cover 1, exposing the interior of the well ring reinforcement 2 and the structure of the placement groove 201.

[0038] The operator inserts their finger into the pull groove 405 of the warning ring 401 and pulls the warning ring 401 upward, causing the long rod 402 to move upward synchronously within the well ring reinforcement 2, pulling the warning ring 401 out of the placement groove 201 until it reaches a height that is easy to operate. Generally, the warning ring 401 extends 1-1.5m above the ground.

[0039] By pushing the limiting rod 403 with the actuating plate 404, it slides out of the groove 202 and inserts into the limiting hole on the long rod 402, fixing the position of the warning ring 401. At this time, the warning ring 401 extends out of the well ring reinforcement 2 and uses its warning coating to warn surrounding personnel and remind irrelevant personnel to stay away from the work area.

[0040] The operator holds the pull rod 302 on the filter plate 301 and pulls multiple sets of filter plates 301 upward from inside the well ring reinforcement 2 in sequence to clean the impurities trapped on the filter plates 301. After cleaning, the filter plates 301 are put back into their original positions inside the well ring reinforcement 2 through the pull rod 302 to ensure that the filter plates 301 are installed securely.

[0041] After cleaning, hold the warning ring 401 with one hand, and then pull the limit rod 403 out of the limit hole by using the toggle plate 404, so that the warning ring 401 falls back into the placement groove 201, and the pull-up groove 405 is placed back in the groove 202. Then, put the well cover 1 back on top of the well ring reinforcement 2 to restore the device to normal use.

[0042] Second implementation method:

[0043] Figure 6 The diagram shows an integrated device for collecting rainwater from manhole covers. An electric telescopic rod 601 is fixedly installed below the manhole ring reinforcement 2. A water-blocking plate 602 is fixedly connected to the telescopic end of the electric telescopic rod 601. A water-blocking ring 603, matching the water-blocking plate 602, is fixedly connected to the inner wall of the manhole ring reinforcement 2. Through the arrangement of the water-blocking plate 602 and the water-blocking ring 603, filtered water flowing in can be intercepted. A water collection well 5 is provided on the side of the manhole ring reinforcement 2. A connecting pipe 7 is installed on the water-blocking ring 603 of the manhole ring reinforcement 2, and the connecting pipe 7 is connected to the water collection well 5. A water level sensor 501 is installed inside the water collection well 5.

[0044] The electric telescopic pole 601 is installed at the bottom of the well ring reinforcement 2. It adopts a waterproof and corrosion-resistant electric drive structure. Its telescopic end is vertically upward and is powered by the municipal street light power supply line. The water level sensor 501 controls the raising and lowering of the water baffle 602.

[0045] During rainfall, rainwater is filtered by filter plate 301 and flows into the space below well ring reinforcement 2. If the water level in the collection well 5 is lower than the preset storage threshold, that is, the water level sensor 501 does not contact the water, the telescopic end of the electric telescopic rod 601 retracts, pushing the water-blocking plate 602 to move upward and fit against the water-blocking ring 603, blocking the water flow. Rainwater flows into the collection well 5 for storage through the connecting pipe 7. There is a possibility that water will flow away through the gaps, but most of the water will enter the collection well 5.

[0046] When the water level in the collection well 5 reaches the preset upper limit, the water level sensor 501 comes into contact with the water and sends a signal. The built-in control module commands the electric telescopic rod 601 to extend, and the water-blocking plate 602 moves upward to release the blockage. Subsequent rainwater and excess water flow into the sewage pipe through the lower part of the well ring reinforcement 2 and are discharged away. On non-rainy days, the water stored in the collection well 5 can be used for urban greening (the pipe between the collection well 5 and the greening pipe is pre-buried and installed), thereby realizing the full utilization of rainwater.

[0047] The power supply relies entirely on the municipal street light lines to ensure stable operation of the equipment. During the regular inspection of the municipal street lights, maintenance personnel simultaneously check the power supply and signal transmission of the electrical components of this device, such as the electric telescopic pole 601 and the water level sensor 501, promptly repairing faults and clearing debris to ensure the long-term reliable operation of the device.

[0048] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
