Description

Technical Field

[0001] The utility model belongs to the field of municipal drainage, and specifically relates to an inlet culvert of an underground rainwater storage tank. Background Art

[0002] Under the background of the increasingly accelerating urbanization process in China, the improvement of the quality and speed of urbanization is continuously promoted, and the problem of urban waterlogging has become increasingly prominent, which has become a key problem faced by many regions. In recent years, urban areas have been frequently hit by heavy rains, and waterlogging incidents have occurred repeatedly, which have had an extremely serious impact on the personal and property safety of the masses.

[0003] To cope with urban waterlogging, multi-functional storage tanks are generally used to absorb excessive rainwater at present. Among them, the design of the inlet culvert of the underground storage tank is crucial, which is the core element to realize the combined use of normal and disaster situations. In the case of small-scale rainfall, the inlet culvert must ensure that rainwater does not flow into the storage tank randomly, so as to ensure that the underground storage space can be used for other conventional purposes such as parking and warehouses in daily life. When encountering short-duration large-scale disaster heavy rains, the inlet culvert should ensure that the water intake is opened in time to effectively collect the excessive rainwater in the catchment area. At the same time, the energy dissipation stairs and porous exhaust pipes set in the culvert play an important role. They can effectively dissipate energy and discharge the gas in the underground storage tank in time, so that the excessive rainwater can flow into the storage tank quickly, thereby ensuring that there is no waterlogging in the area.

[0004] However, the existing structure of the rainwater inlet culvert is relatively simple. Usually, it is only connected to the road rainwater grate and has a certain slope to discharge rainwater to the downstream storage tank or river. Although this traditional design can relieve the phenomenon of urban waterlogging to a certain extent, it has obvious limitations. Specifically, in the face of disaster heavy rains, relying solely on this conventional culvert to collect rainwater cannot achieve the combined use of normal and disaster situations. That is to say, in the case of small-scale rainfall, rainwater may still flow into the underground storage space, thus affecting its normal use as functions such as parking and warehouses in normal times. When large-scale heavy rains come, due to problems in exhaust and energy dissipation, the culvert cannot achieve the function of quickly collecting rainwater, which makes the underground storage tank unable to play its role in time and effectively, thus affecting the drainage effect of the whole area and increasing the risk of waterlogging. Summary of the Utility Model

[0005] In view of these problems, this solution proposes an inlet culvert with water collection and energy dissipation functions to solve the existing problems. The utility model monitors through a rain gauge and other devices, and multiple components cooperate to control the opening and closing of the water intake and the quick-closing gate well, and is provided with an energy dissipation and exhaust structure to ensure the combined use of normal and disaster situations and the drainage function.

[0006] To achieve the above object, the present utility model specifically adopts the following technical solutions:

[0007] An inlet culvert for an underground rainwater storage tank, comprising a rain gauge and a water level monitoring equipment control cabinet, a rainwater intake, a water intake culvert, a quick-closing gate well, an exhaust pipe, and an energy dissipation staircase;

[0008] The rain gauge and the water level monitoring equipment control cabinet are installed at the low point of the road to monitor the rainwater level on the road during rainfall; a rainwater intake is provided at the end of the water intake culvert, and a stainless steel grille cover plate is installed on the top of the rainwater intake. A movable waterproof cover plate for daily maintenance is synchronously provided at the rainwater intake. The stainless steel grille cover plate can be opened, and maintenance personnel can enter the interior of the rainwater intake through a ladder for daily maintenance; the rainwater intake is controlled to open and close by a hydraulic discharge gate, and the gate is fixed by a hydraulic rod and a pre-embedded rotating shaft. The hydraulic rod is jointly controlled by a hydraulic station and a PLC control cabinet on the ground to control the opening degree of the hydraulic discharge gate; the rainwater intake is connected to the quick-closing gate well through the water intake culvert, and a valve hoist on the ground is used to control the gate in the quick-closing gate well. The hoist can be manually operated on-site or remotely controlled in the cloud.

[0009] Further, the quick-closing gate well includes a flow-regulating quick-closing gate and a flow-regulating safety gate. The flow-regulating quick-closing gate is used to quickly open when collecting flood water, and the flow-regulating safety gate is used to ensure that rainwater cannot enter the emergency storage space through the culvert after the rainfall ends when the quick-closing gate fails to close due to the impact of a large amount of water.

[0010] Further, an energy dissipation staircase is provided at the connection of the water intake culvert and the underground space. The energy dissipation staircase is arranged annularly according to the height difference, and an exhaust pipe is installed in the middle of the staircase according to the amount of gas discharged from the underground space. The side wall of the exhaust pipe is provided with holes, and an exhaust cap is arranged above the ground at the upper end. A stainless steel wire mesh is arranged at the connection of the water intake culvert and the underground space to separate the functions of the underground space and the culvert, and prevent underground insects, rats and larger garbage from entering the culvert.

[0011] Further, the quick-closing gate well is also provided with a movable waterproof cover plate for maintenance, and a ladder is also installed below the movable waterproof cover plate, which is convenient for maintenance personnel to carry out daily maintenance and post-disaster restoration.

[0012] Further, the energy dissipation staircase and the exhaust pipe are combined in design. The energy dissipation staircase wall has a cantilever design, and stairs are arranged around it. An exhaust main pipe is arranged in the middle of the stairs, and ventilation holes are reserved on the side wall of the exhaust pipe according to the calculated number of holes, so that the gas in the underground space can enter the main pipe and be discharged through the exhaust cap on the ground.

[0013] This solution has the following beneficial technical effects:

[0014] In this solution, a quick-closing gate well and a controllable gate valve are set up, which can effectively deal with waterlogging, enabling the waterlogging to quickly flow into the underground storage space and improving the drainage efficiency. The design of the energy dissipation staircase can prevent the instantaneous large-scale waterlogging from damaging the bottom of the culvert, ensuring the safety of the facilities. At the same time, the exhaust pipe is combined with the energy dissipation staircase to discharge the underground gas synchronously when the waterlogging flows into the underground space, ensuring the stability of the drainage process. In addition, the stainless steel grille cover plate prevents foreign objects from blocking and people from falling, improving safety. Moreover, through the remote control system, disasters such as heavy rain can be responded to in a timely manner, and the hydraulic discharge gate can be quickly opened, improving the emergency response ability. Finally, a flow-regulating safety gate is set up to prevent secondary damage when the flow-regulating quick-closing gate is damaged, improving the reliability and stability of the facilities.

[0026] The following uses specific specific examples to illustrate the implementation manners of the present utility model. Those skilled in the art can easily understand the other advantages and effects of the present utility model from the content disclosed in this specification. The present utility model can also be implemented or applied through other different specific implementation manners. The details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present utility model. It should be noted that the diagrams provided in the following embodiments only illustrate the basic concept of the present utility model in a schematic manner. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0027] The water collection and energy dissipation inlet culvert for cooperating with the underground emergency storage tank is as Figure 1-3 shown. This device includes a rainwater inlet well body, and the quick-closing gate well is located in the middle section of the water collection culvert. The water collection culvert is connected to the underground storage space. The waterlogging water is collected through the rainwater collection port and enters the culvert. The gate valve in the gate valve well that is opened synchronously allows the waterlogging water to flow into the energy dissipation staircase, and the waterlogging water flows along the staircase into the underground storage space.

[0028] As Figure 1 、 2 shown, the exhaust pipe is connected from the water collection culvert to the ground and is connected to the exhaust cap. The exhaust cap is arranged according to the green vegetation of the ground landscape and is integrated into the overall landscape effect in combination with the landscape design. When the waterlogging water flows into the underground storage space through the inlet culvert, the gas in the underground storage space is discharged synchronously through the personnel access and the ground exhaust pipe. The connection with a high elevation difference between the water collection culvert and the underground storage space is as Figure 2 shown. An energy dissipation staircase is set to prevent instantaneous large-scale waterlogging water from causing destructive impact on the bottom of the inlet culvert. The waterlogging water rotates and flows down along the energy dissipation staircase and flows from the water collection position with a higher elevation to the underground emergency storage tank inlet with a lower elevation.

[0029] As Figure 4 、 5The energy dissipation staircase is combined with the exhaust pipe as shown. The exhaust pipe is located in the middle of the energy dissipation staircase. The floodwater flows into the underground storage space through the staircase, and at the same time, the gas in the underground space is discharged. The energy dissipation staircase is composed of steps and platforms, which are distributed annularly in the blind channel shaft. The first platform is connected to the bottom plate of the intake blind channel. The steps at the bottom of the staircase are connected to the inlet of the underground emergency storage tank. The exhaust pipe is combined with the staircase platform at the top plate of the inlet of the underground emergency storage tank as the gas collection port.

[0030] As Figure 6 , 7 shown, the stainless steel grille cover plate above the rainwater collection port can prevent foreign objects from blocking above the rainwater inlet and people from falling. During a catastrophic rainstorm, the road flooding data is sent to the cloud through the rain gauge and the water level monitoring equipment control cabinet for the control personnel to decide the timing of using the underground storage space. The control personnel remotely control the control cabinet to operate the hydraulic rod through the hydraulic station. The hydraulic discharge gate is quickly converted from the closed state (opening degree 0°) to the open state (opening degree 90°) through the rotating shaft, and the floodwater enters the inside of the blind channel through the rainwater collection port.

[0031] As Figure 8-10 shown, the valve in the quick-closing gate valve well is controlled to open and close by the hoist. The gate valve well is provided with a flow-regulating safety gate and a flow-regulating quick-closing gate respectively according to the water inflow direction. After the flood disaster, when the flow-regulating quick-closing gate is damaged due to excessive water volume, the flow-regulating safety gate can be closed to prevent secondary damage to the flow-regulating quick-closing gate caused by small-scale rainfall during the maintenance process.

[0032] The above are only the preferred embodiments of the present invention and do not impose any form of limitation on the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
