Problems solved by technology

At present, there are two types of manhole covers that are often used in drainage systems. The first type is represented by various solid forms such as cast iron manhole covers, high-strength fiber cement concrete manhole covers, and resin manhole covers. Prevent debris from falling, but the drainage capacity is relatively poor, and water accumulation is prone to occur when the rainfall is concentrated; the second type is represented by rainwater grate, which has many holes on the surface, good drainage capacity and fast drainage, but Easy to drop debris, causing sewer blockage

Embodiment 1

[0018] Such as Figure 1~4 Example 1 of the present invention is shown: a buoyancy type self-opening and closing system for a well cover, including a cover body 1, a drain port 3 is opened on the cover body 1, and the drain port 2 is provided with a drain port 2 controlled by rotation to open Closed flap 3, the flap 3 is provided with a drain hole 4; the cover 1 is also provided with a buoyancy block 5, and the cover 1 is provided with a cross bar 6 hanging on the buoyancy block. The rod is provided with a pull rope 7 for pulling and controlling the rotation of the flap 3. Since the water collection wells are set in the lower part of the road, when draining water in rainy days, the accumulated water is deepest here, so the maximum buoyancy can be formed fastest here.

[0019] When there is no rain or when there is little rain, the flap 3 will turn upward to close the drain under the pull of a rope, so that the manhole cover is convenient for driving and pedestrians, and it can av...

Embodiment 2

[0040] Such as Figure 5 The second embodiment of the present invention is shown: the difference between this embodiment and the first embodiment is that the steering structure of the drawstring is different. In this embodiment, the lower part of the other side of the drain port 2 is provided with a notch 12, which is provided with a steering Shaft 13, the upper end of the pull rope passes through the gap between the steering shaft and the notch and then is connected with the flap so that when the crossbar goes down, it pulls and turns upwards to close the drain. The steering shaft 13 has less wear on the pull rope.

[0041] A working method of a manhole cover buoyancy self-opening and closing system includes the above-mentioned manhole cover buoyancy self-opening and closing system. When there is less rain, the flap is stretched to close the drain, and rainwater can drain through the flap. The hole drains away; when the rain is too heavy and there is water on the road, the water ...

Abstract

The invention relates to a well lid buoyancy type self open-close system and an operation method thereof. The system comprises a lid body. The lid body is provided with water outlets. The water outlet is internally provided with a turnover panel which controls on-off of the water outlet through rotation. The turnover panel is provided with a weep hole. The lid body is also provided with a buoyancy block. A cross rod hung on the buoyancy block is arranged below the lid body. The cross rod is provided with a stay cord used to pull and control the turnover panel to rotate. The well lid buoyancy type self open-close system drains away water through the weep holes when little rainwater exists, and can automatically open the water outlets when much rainwater exists, so as to expand drainage area to accelerate drainage, and the system is not easy to block and solves a problem of surface gathered water. The system is reliable and stable, and is long in service life, convenient in changing, and good in economic benefit.

Description

Technical field [0001] The invention relates to a well cover buoyancy type self-opening and closing system. Background technique [0002] In recent years, the phenomenon of urban waterlogging is relatively common and becoming more serious. One reason is that the municipal drainage system is not properly planned; the other is that the drainage facilities are defective. At present, there are two types of manhole covers often used in drainage systems. The first type is represented by various solid forms such as cast iron manhole covers, high-strength fiber cement concrete manhole covers, resin manhole covers, etc. The surface of this type of manhole cover has few holes and has good driving effect. Prevent debris from falling, but the drainage capacity is relatively poor, and the phenomenon of water accumulation is prone to occur when rainfall is concentrated; the second type is represented by rainwater grate and other forms. This type of manhole cover has many holes on the surface, ...
