Description

A self-closing rainwater outlet that is easy to clean

technical field

The utility model belongs to the technical field of drainage and relates to an easy-to-clean automatically closed rainwater outlet.

Background technique

In recent years, urban waterlogging has occurred frequently in my country, which seriously threatens the safety of residents' lives and properties. In addition to the increase in extreme rainstorms, the low drainage capacity of rainwater outlets and the blockage of sewage are also important reasons for urban waterlogging. The gully is the main subsidiary structure of the urban drainage pipeline system, and it is also an important part of urban road drainage. The rainwater outlet is located at the beginning of the urban drainage system, and is usually set at a certain distance from municipal roads, squares, street intersections and street gutters. The gully is the starting point of the urban drainage system, which has the function of collecting rainwater and intercepting sewage. The scientific and rational design of the sewage interception outlet can reduce the phenomenon that leaves and other garbage block the rainwater outlet, causing rainwater to flood the road, or causing water accumulation in roads and low-lying areas to form waterlogging points, hindering traffic or damaging roads. As a pavement drainage pollution control facility, stormwater interceptors are particularly important in structural design. Therefore, while waterlogging control is rationally designed, updated, managed and maintained, and LID measures are adopted, attention should be paid to the design of urban road stormwater outlets in the design of drainage pipe networks. Reasonable renovation of existing rainwater outfalls.

At present, the top surface of most gullies for road laying is the grate of the rain well, the bottom is the shaft of the gully, and there are rainwater branch pipes at the bottom to connect the rain well. There are many holes on the grate of the rain well. Rainwater wells, as well as artificially dumped sewage and household garbage, can easily enter rainwater wells, causing blockage of sewer channels and forming waterlogging spots during rainy periods. In order to reduce blockage and improve drainage performance, it is necessary to regularly open the rainwater grate to clean up the internal garbage, which is time-consuming, laborious and dangerous, and has caused many accidents of people falling and causing death and injury. The cleaning of rainwater outlets on the road also greatly affects the smooth flow of urban road transportation and traffic safety. Garbage such as leaves deposited in the gullies will ferment and rot under the rainwater and emit peculiar smells, pollute the surrounding air, and may cause pipeline explosions, causing major economic losses and adverse social impacts.

Need a kind of novel gully design badly for this reason and solve the problem that gully is easy to block, cleans up inconvenience.

The utility model will be described in further detail below through specific embodiments in conjunction with the accompanying drawings. Wherein, similar elements in different implementations adopt associated similar element numbers. In the following implementation manners, many details are described for better understanding of the present application. However, those skilled in the art can readily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods. In some cases, some operations related to the application are not shown or described in the description, this is to avoid the core part of the application being overwhelmed by too many descriptions, and for those skilled in the art, it is necessary to describe these operations in detail Relevant operations are not necessary, and they can fully understand the relevant operations according to the description in the specification and general technical knowledge in the field.

In the utility model, the serial numbers for the components are only used to distinguish the described objects, and do not have any sequence or technical meaning. The "connection" and "connection" mentioned in this application include direct and indirect connection (connection) unless otherwise specified.

Fig. 1 is the structural representation of the utility model. As shown in Figure 1, the utility model easy-to-clean automatic sealing rainwater outlet includes a rainwater outlet body 1, a rainwater well grate 2, an automatic reset spring hinge 3, a porous water-absorbing material 4, a sewage intercepting hanging basket 5, and a hanging basket lifting handle. Hand 6, rainwater branch pipe I7 and rainwater branch pipe II8, small overflow hole 9 and large overflow hole 10.

FIG. 2 is a schematic diagram of an automatic closing structure, and FIG. 3 is a top view of a porous water-absorbing material, including an automatic return spring hinge 3 and a porous water-absorbing material 4 . In the rainy season, the porous water-absorbing material 4 will absorb water and the gravity will increase, and the original horizontal automatic return spring hinge 3 will be pressed to a certain angle. The larger the spring compression in the return spring hinge 3 is, the larger the opening angle between the automatic return spring hinge 3 and the ground will be, so that the greater the flow, the larger the drainage area of the rainwater outlet.

In the non-rainy period, the porous water-absorbing material 4 is in a loose state, its own weight is small, and its gravity is far less than the bearing capacity of the automatic return spring hinge 3, the automatic return spring hinge 3 is closed, the porous water-absorbent material 4 remains horizontal, and the rainwater outlet remains closed. Garbage such as fallen leaves will only fall on the surface of the rainwater outlet, and can be cleaned manually, which effectively reduces the garbage entering the rainwater outlet and avoids human dumping. At the same time, odors cannot escape from the rainwater well, reducing air pollution.

Fig. 4 is a top view of the hanging basket for intercepting dirt, including hanging basket 5 for intercepting dirt, handle 6 for hanging basket, small overflow hole 9 and large overflow hole 10. Water in the rainy season flows into the sewage interception hanging basket 5 through the rainwater outlet well grate 2, and when the rainwater well water collection capacity is less, the water overflows from the overflow aperture 9 and enters the drainpipe. The fallen leaves rubbish that is flushed into by the sand grain of overflow aperture 9 and the rainy period are trapped in the hanging basket 5 that intercepts the dirt, and are taken out and cleaned regularly manually. When the water collection capacity of the rainwater well is so large that the filtration rate cannot meet the drainage needs, the water overflows from the large overflow hole 10 of the sewage intercepting hanging basket 5 .

Rainwater mainly flows into the urban pipe network through the rainwater branch pipe Ⅱ8, and is discharged into lakes or rivers; when the rainfall is heavy and the water at the bottom of the rainwater well sinks to the higher rainwater branch pipe Ⅰ7, the rainwater branch pipe Ⅱ8 and the rainwater branch pipe Ⅰ7 simultaneously discharge water, and the rainwater branch pipe Ⅰ7 and the rainwater branch pipe Ⅰ7 The storage tanks are connected, and the storage tanks can store a certain amount of rainwater, which can reduce the pressure of the rainwater pipe network when the rainfall is large. At the same time, the water in the storage tank can be used for surrounding greening and road sprinkling, and when it is located around the building, it can be used for car washing and toilet cleaning.

The above application is used to specifically illustrate the utility model, which is only used to help understand the utility model, and is not intended to limit the utility model. For those skilled in the technical field to which the utility model belongs, some simple deduction, deformation or replacement can also be made according to the idea of the utility model.
