Description

Technical Field

[0001] This utility model relates to the field of municipal engineering design, and in particular to a drainage device for municipal engineering design. Background Technology

[0002] Municipal engineering design, as a core component of urban planning and construction, plays a decisive role in the effective functioning of cities. In the daily operation of a city, the drainage system is crucial. It not only affects urban environmental sanitation but is also a key link in ensuring the normal operation of urban infrastructure and protecting residents' lives from floods. An efficient and stable drainage system is the cornerstone of sustainable urban development. Drainage devices, as core components of the drainage system, directly influence the overall operational effectiveness of the system through their manufacturing processes and performance. With the continuous expansion of urban scale and the accelerated pace of urbanization, more stringent requirements are being placed on drainage devices in terms of drainage capacity, durability, and ease of maintenance.

[0003] Existing drainage devices for municipal engineering projects are diverse in type and widely used. In road drainage, common rain grates collect rainwater from the road surface through surface openings and guide the water flow into underground drainage pipes. Their structure is relatively simple, and they are mostly made of metal to ensure a certain level of strength and durability. However, there is a lack of a convenient and easy-to-use anti-clogging filter device to solve the problem of separating water and debris in rainwater discharge. After debris enters the drainage pipe, it accumulates inside the pipe. Over time, the accumulated debris will increase, eventually leading to pipe blockage, causing road flooding and affecting traffic. Therefore, a drainage device for municipal engineering projects is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a drainage device for municipal engineering design, which aims to improve the problem of pipe blockage caused by the accumulation of debris due to the lack of easy-to-use and clean anti-clogging filter devices in the existing technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A drainage device for municipal engineering design includes a well base, a rotating block fixedly connected inside the well base, a well cover fixedly connected to the side wall of the rotating block, the well cover slidably connected inside the well base, a handle fixedly connected to the side wall of the well cover, a lifting mechanism provided at the bottom of the well base, and a deodorizing mechanism provided at the bottom of the well cover.

[0007] The lifting mechanism includes a base frame, which is fixedly connected to the bottom of the manhole cover. A sliding frame is slidably connected inside the base frame. A sliding groove is opened inside the sliding frame. A sliding shaft is slidably connected inside the sliding groove. A pull rod is rotatably connected to the side wall of the sliding shaft. A fixed shaft is fixedly connected to the side wall of the manhole cover. One end of the pull rod is rotatably connected to the side wall of the fixed shaft. A filter screen is provided inside the sliding frame.

[0008] As a further description of the above technical solution:

[0009] The deodorization mechanism includes a placement plate and an activated carbon plate. The placement plate is fixedly connected to the bottom of the manhole cover, and a limiting block is provided on the side wall of the placement plate. The activated carbon plate is placed at the bottom of the manhole cover and is slidably connected inside the placement plate.

[0010] As a further description of the above technical solution:

[0011] A magnetic block one is fixedly connected to the side wall of the placement plate, a hinge is fixedly connected to the bottom of the placement plate, a baffle is fixedly connected to the side wall of the hinge, and a magnetic block two is fixedly connected to the side wall of the baffle. The magnetic block one and the magnetic block two are magnetically attracted to each other.

[0012] As a further description of the above technical solution:

[0013] The manhole cover has a drainage outlet inside, which is angled to increase the water flow.

[0014] As a further description of the above technical solution:

[0015] The base frame is fixedly connected to a support rod, and a slide rail is provided inside the base frame.

[0016] As a further description of the above technical solution:

[0017] The sidewall of the sliding frame is slidably connected to the inside of the slide rail, and the bottom of the sliding frame is fixedly connected to a base.

[0018] As a further description of the above technical solution:

[0019] A handle is fixedly connected to the top of the filter screen.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, pulling the manhole cover drives the pull rod, and the other end of the pull rod drives the sliding shaft. While the sliding shaft slides in the slide groove, the sliding frame rises along the slide rail, finally bringing out the filter screen. Then the filter screen can be taken out for cleaning. After cleaning, the filter screen can be retracted while the manhole cover is lowered. This not only filters rainwater but also makes cleaning the filter screen more convenient and quick. Even if the filter screen is blocked due to excessive garbage, rainwater can still flow out through the gap between the manhole cover and the sliding frame, preventing the channel from being blocked and causing water accumulation on the road. This reduces the blockage of drainage channels and makes it easier for workers to clean the filter screen.

[0022] 2. In this utility model, by opening the manhole cover, then pulling open the baffle on the placement plate using the hinge, pressing the old activated carbon plate to fit the manhole cover, and then pushing it out, a new activated carbon plate is pushed in close to the manhole cover and aligned with the placement plate. The limiting block set at the inlet of the placement plate will fix the activated carbon plate. Then the baffle is closed, so that the magnetic blocks on both sides fit together. When a vehicle passes by, the manhole cover will shake and the activated carbon plate will not be shaken out. In addition, the drainage outlet on the manhole cover is an angled hole, which increases the water flow and allows sewage to pass through the filter screen as much as possible. The activated carbon plate can reduce the odor of the sewage outlet and beautify the city road. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3 This utility model provides an embodiment of a drainage device for municipal engineering design, comprising a manhole base 1, a rotating block 2 fixedly connected inside the manhole base 1, a manhole cover 3 fixedly connected to the side wall of the rotating block 2, the manhole cover 3 slidably connected inside the manhole base 1, a handle 4 fixedly connected to the side wall of the manhole cover 3, a lifting mechanism at the bottom of the manhole base 1, and a deodorizing mechanism at the bottom of the manhole cover 3. The lifting mechanism includes a base frame 5 fixedly connected to the bottom of the manhole base 1, a sliding frame 7 slidably connected inside the base frame 5, a sliding groove 9 inside the sliding frame 7, a sliding shaft 10 slidably connected inside the sliding groove 9, and displacement acting on the sliding shaft 10. A pull rod 11 is rotatably connected to the side wall of the sliding shaft 10, a fixed shaft 12 is fixedly connected to the side wall of the manhole cover 3, one end of the pull rod 11 is rotatably connected to the side wall of the fixed shaft 12, and the fixed shaft 12 is used to drive the pull rod 11. The sliding shaft 10 will move upwards on the pull rod 11. While being pulled up, the slide frame 7 slides within the chute 9, causing it to rise. Therefore, when the manhole cover 3 is pulled up, the sliding frame 7 is moved by the pull rod 11. A filter screen 8 is installed inside the sliding frame 7, which serves as the carrier for the filter screen 8 and is used to move the filter screen 8. A support rod 14 is fixedly connected inside the base frame 5 to support the sliding frame 7 and prevent it from falling, thus increasing the reliability of the equipment. A slide rail 6 is provided inside the base frame 5 to reduce the resistance to the upward movement of the sliding frame 7, making it easier to be pulled up. The side wall of the sliding frame 7 is slidably connected to the slide rail 6. A base 15 is fixedly connected to the bottom of the sliding frame 7, which is used to fix the filter screen 8. A handle 13 is fixedly connected to the top of the filter screen 8, which allows workers to easily remove the filter screen for cleaning. A drain outlet 19 is provided inside the manhole cover 3. The drain outlet 19 is opened at an angle to increase the water flow and cause the water to gather in the center and flow towards the filter screen, thereby enhancing the filtration effect.

[0033] Reference Figures 4-6The deodorization mechanism includes a placement plate 16 and an activated carbon plate 17. The placement plate 16 is fixedly connected to the bottom of the manhole cover 3 and is used to place the activated carbon plate 17. A limiting block 18 is provided on the side wall of the placement plate 16. The activated carbon plate 17 is placed at the bottom of the manhole cover 3 and is slidably connected inside the placement plate 16. After the activated carbon plate 17 is placed inside the placement plate 16, the limiting block 18 is used to fix the activated carbon plate 17 and prevent it from falling off the placement plate 16 when the equipment shakes, thus improving its stability. A magnetic block 20 is fixedly connected to the side wall of the placement plate 16, and a hinge 21 is fixedly connected to the bottom of the placement plate 16. A baffle 22 is fixedly connected to the side wall of the hinge 21, and a magnetic block 23 is fixedly connected to the side wall of the baffle 22. Magnetic blocks 20 and 23 are magnetically attracted to each other. The baffle 22 is used to close the placement plate 16. After opening and closing, the activated carbon plate 17 can be replaced, and it is further fixed to prevent it from falling off the placement plate 16. The overall mechanism has the effect of reducing the odor of the sewage outlet and beautifying the urban road.

[0034] Working principle: First, pull the manhole cover 3 upwards using handle 4. The manhole cover 3 is lifted upwards by rotating block 2. At the same time as it is lifted, the fixed shafts 12 on both sides of the manhole cover 3 will drive the pull rod 11. The pull rod 11 will pull the sliding shaft 10. Due to the angle, the sliding shaft 10 will slide in the slide groove 9 while the pull rod 11 is pulled upwards, and drive the sliding frame 7 to rise. When the sliding frame 7 is pulled upwards, it will slide upwards along the slide rail 6 opened inside the base frame 5. When the manhole cover 3 is pulled to its maximum, the sliding frame 7 will also rise to the ground. At this time, the filter screen 8 can be lifted out using handle 13. After cleaning, the filter screen 8 can be put back into the sliding frame 7. The base 15 at the bottom of the sliding frame 7 can fix the filter screen 8. Then, pull the manhole cover 3 upwards using handle 4. Pulling down, the sliding frame 7 slides down the slide rail 6 until the handle 4 is in contact with the well base 1. At the same time, the support rod 14 at the bottom of the base frame 5 will also support the sliding frame 7. When the well cover 3 is pulled up, the activated carbon plate 17 can also be replaced at the same time. First, pull open the baffle 22 through the hinge 21, then press the activated carbon plate 17 so that it is tightly attached to the well cover 3. Then push out the activated carbon plate 17 for replacement. Push the new activated carbon plate 17 tightly into the placement plate 16, avoiding the limiting block 18. When it is fully pushed in, release the activated carbon plate 17 so that it falls into the placement plate 16. Then close the baffle 22. The magnetic block 23 on the baffle 22 will be tightly attracted to the magnetic block 20 on the placement plate 16. The drain outlet 19 on the well cover 3 is opened at an angle to increase the water flow.
