Description

Technical Field

[0001] The invention relates to the field of sewage discharge, in particular to a municipal sewage discharge device and method. Background Art

[0002] In the city's infrastructure system, the drainage system plays a vital role. Among them, road manholes, as key nodes of the drainage system, play an indispensable role in the rapid discharge of rainwater. However, in heavy rain weather, blockages are very likely to occur, which in turn leads to waterlogging on the roads, posing many hidden dangers to urban traffic, residents' lives and infrastructure safety; whenever heavy rain falls, a large amount of rainwater quickly converges on the road, forming a turbulent flow. According to normal drainage design, these water flows should quickly flow into the drainage pipes through the manholes to avoid large accumulations on the road surface. When the intensity of the heavy rain exceeds expectations, or the manholes are blocked, waterlogging on the roads will form quickly.

[0003] There are many reasons for the blockage of road manholes. During heavy rains, as the rain washes away, all kinds of debris on the road, such as branches, leaves, garbage, etc., will be washed into the manholes. Driven by the water flow, these debris can easily accumulate at the manhole mouths, thereby blocking the manholes. Especially in some old urban areas, there are many trees on both sides of the road. When heavy rains are accompanied by strong winds, branches are broken and fall directly onto the road surface, and then rush into the manholes with the water flow. Moreover, the garbage on some roads is not cleaned up in time, which also lays hidden dangers for the blockage of manholes.

[0004] In summary, the problem of road waterlogging caused by road manhole blockage during heavy rain has become an important factor affecting the normal operation of cities and the quality of life of residents. How to effectively solve this problem and ensure the smooth flow of urban drainage systems is a difficult problem that needs to be overcome in current urban construction and management.

When the manhole cover 1 closes the manhole opening, the supporting mechanism 2 is pressed tightly so that the supporting mechanism 2 is firmly installed and will not loosen during use. When the drainage mechanism 3 needs to be disassembled, it is only necessary to open the manhole cover 1 first to take out the drainage mechanism 3, which is simple and convenient to operate. The clamping mechanism 4 is provided to assist in supporting the drainage mechanism 3 so that the drainage mechanism 3 can be more firmly connected to the manhole during use. When the drainage mechanism 3 is squeezed by rainwater, the drainage mechanism 3 squeezes the clamping mechanism 4 downward, and the clamping mechanism 4 is clamped on the inner wall of the manhole.

[0041] In one embodiment, please refer to the attached manual. Figure 1 and 3 As shown in Figure 9, the drainage mechanism 3 includes a crushing component and a drainage component. The crushing component is used to crush the blockage, and the drainage component provides rotational force for the crushing component by spraying sewage; the drainage component discharges the sewage discharged from the crushing component to the bottom of the manhole;

[0042] The crushing assembly includes a sealing platform 33 arranged on the supporting mechanism 2, and a plurality of drainage grooves 312 are opened on the sealing platform 33. Rotating plates 31 corresponding to the drainage grooves 312 are installed inside the rotating plates 31, and convex plates 32 are arranged on the rotating plates 31 in a one-to-one manner. The convex plates 32 rotate to scrape off the blockages; a plurality of drainage holes 34 are arranged on the outer circumference of the sealing platform 33, and the drainage holes 34 correspond to the drainage grooves 312 in a one-to-one manner.

When the water is small, the water flow will be discharged downward from the interior of the drainage hole 34, and the water flow will enter the interior of the water receiving groove 36 below. The water inside the water receiving groove 36 drives the water receiving groove 36 to move downward, and the water receiving groove 36 drives the bearing 38 to move downward along the direction of the shaft 301. At this time, the bearing 38 squeezes the clamping mechanism 4 and is tightened on the inner wall of the manhole; at the same time, the sealing ring 35 will produce relative movement with the water receiving groove 36. When the water receiving groove 36 moves downward, the water receiving groove 36 drives the rotating plate 31 to move downward synchronously.

[0054] In order to utilize the gravitational potential energy of rainwater falling downwards; the spiral blades 53 are impacted by rainwater, and the spiral blades 53 rotate. The rotation of the spiral blades 53 drives the rotating seat 51 to rotate, and the rotating seat 51 rotates. The rotating seat 51 is connected to the outer rod sleeve. The rotation of the outer rod sleeve applies power to the rotating plate 31, which increases the rotational force of the rotating plate 31 and facilitates the rapid rotation of the rotating plate 31, thereby breaking and cutting the blockage and preventing blockage.

[0055] When the present invention is in use, when heavy rain or sewage passes through the manhole cover 1 and enters the rotating plate 31, water above the rotating plate 31 will enter the interior of the drainage groove 312.

When the water receiving groove 36 moves downward, the water receiving groove 36 drives the rotating plate 31 to move downward synchronously When the rotating plate 31 moves downward, it will be staggered with the sealing platform 33. When the sealing platform 33 is opened, it is convenient for more rainwater to flow downward, and the rainwater quickly enters the inside of the water receiving groove 36.

For crushing and cutting; when the bearing 38 moves downward, the first telescopic rod 44 and the first stabilizing rod 43 are acted upon by the spring, and the card plate 42 will be initially stuck on the inner wall of the manhole, making the disassembly and installation process more convenient; after receiving more rainwater, the water receiving trough 36 drives the bearing 38 to move downward, and the bearing 38 moves to squeeze the lower pressure rod 45 to move, and the lower pressure rod 45 moves to squeeze the second telescopic rod 47, and the second telescopic rod 47 drives the second stabilizing rod 48 to move downward, and then the second telescopic rod 47 pushes the second stabilizing rod 48 to move, and the second stabilizing rod 48 moves to drive the card plate 42 to move, so that the card plate 42 is more closely fitted to the inner wall of the manhole.
