The invention discloses an automatic water retaining device for an underground garage inlet, which comprises a water baffle plate 1, a hydraulic barrel 2, a buoyancy tank 3, an upper water seal 4, a lower water seal 5, a sealing wall 6, a sealing flat plate 7, a drainage ditch 8, a bearing wall 9, a hinged support 10, a communication hole 11 and a rainwater grate 12, and is shown in the attached drawing. Through the mode, the device can automatically start to intercept flood formed by rainstorm and the like to enter the underground garage. The device is arranged in a drainage ditch at the entrance of a garage, when rainwater is small, the rainwater in the water blocking ditch can automatically flow and be discharged, and the device cannot be started at the moment; when rainstorm occurs, water in the drainage ditch cannot be discharged in time of flowing, the drainage ditch is filled with water to overflow, the device is automatically started by hydrostatic pressure at the moment, the water blocking device is turned over, the water blocking plate stands up to block rainwater outside the plate, the higher the water level outside the plate is, and the larger the sealing force is. In operation of the water barrier, emergency vehicles are allowed to pass.

Description

Automatic water blocking device for underground garage entrance

Technical Field

The invention relates to the field of fixed buildings, in particular to a mechanical assembly, and belongs to a fluid pressure actuating mechanism.

Background

At present, urban flood control is a major matter of accident safety, and the main flood control measures at present are that sand bag walls are built manually or water baffle plates are installed and fixed, so that the labor intensity is high, the flood control cost is high, the problems of traffic jam and the like can be caused, and flooding accidents can be caused due to untimely protection of sudden flood.

Disclosure of Invention

The invention mainly solves the technical problem of providing an automatic water retaining device for an underground garage, and can solve the following problems:

1. the entrance of the underground garage is used for installing the water blocking device in place at one time, rainstorm early warning and manual intervention are not needed in advance during working, and flood control cost is low.

2. After rainstorm, flood falls off, and the device automatically resets, so that traffic is not blocked.

3. When the flood control device works, emergency vehicles can pass through.

In order to solve the technical problems, the invention adopts a technical scheme that: the hydraulic bucket is designed in shape and structure, the hydrostatic pressure transfer characteristic is utilized, the hydraulic pressure starting device formed by accumulated water is utilized, and the water baffle is turned over to achieve the purpose of retaining water. The device structure is shown in fig. 1.

The invention has the beneficial effects that:

1. the innovation is as follows: the measure of building the sand bag wall before the artificial rain, except causing the serious inconvenience of life, still can bring very big potential safety hazard to proruption rainstorm, and this design utilizes hydraulics principle design, hydraulic drive, automatic promotion, and the design theory is unique novel. At present, the same product and a principle similar product are not available in the world, and the novel and original effects are achieved.

2. The practicability is as follows: there is not electric apparatus equipment and operating means, need not artifical on duty during the rainstorm, the breakwater is erect automatically when rain-proof ditch water is full, and when rain-proof ditch water whereabouts, the breakwater falls down automatically and keeps flat, when the breakwater erects, also can be through emergent vehicle. The design technology is advanced, the function is reliable and stable, and the requirements on use, maintenance and safety can be met.

3. Environmental protection property: the integral structure aluminum alloy is manufactured, most of structures are in the waterproof ditch, the waterproof plate is exposed and flatly placed on the waterproof ditch, the appearance is neat, and the integral structure aluminum alloy is coordinated with the use environment. No pollutant is produced, and the sediment can be directly washed by water.

4. The economic efficiency is as follows: the one-time investment is about 3-4 times of that of a normal water-proof ditch, but the service life is more than 10 years under normal conditions, and due to the improvement of the safety and the applicability, flood-proof materials and labor cost can be saved every year, and the annual comprehensive cost is not high.

Drawings

Fig. 1 is a structural view of a water guard device. Comprises a water baffle 1, a hydraulic bucket 2, a buoyancy tank 3, an upper water seal 4, a lower water seal 5, a sealing wall 6, a sealing flat plate 7, a drainage ditch 8, a bearing wall 9, a hinged support 10, a communication hole 11 and a rainwater grate 12. When rainstorm occurs, water in the drainage ditch cannot be drained in time of flowing, and under the action of moment generated by hydrostatic pressure, the water blocking device turns over, and the water baffle is erected.

FIG. 2 is a water retaining effect diagram of an entrance of an underground garage according to an embodiment of the present invention; when the drainage ditch is full of water, the water baffle can automatically raise to block water under the action of water pressure and buoyancy, and the water pressure of water on the bottom plate is greater than that of water on the baffle, so that the water baffle cannot automatically topple over, and the water baffle and the side wall are sealed under the action of strong water pressure.

Fig. 3 is a state effect diagram of an underground garage entrance embodiment of the invention when not in operation. When no rainwater exists, the water baffle is turned down and laid horizontally, and vehicles run over from the plate.

Fig. 4 is a force diagram of the water blocking device at the critical starting time. When the device is started, the water pressure F2 does not generate moment, the water pressure F1 and the buoyancy F3 are working moments, and when a certain water level is reached, the gravity moment is overcome, and the device is turned and started.

Fig. 5 is a force diagram of the water blocking device in operation. When the moment generated by the water pressure F2 and the buoyancy F3 is greater than the moment generated by the gravity F1 and the gravity G, the water retaining is stable and reliable.

The specific implementation mode is as follows: the embodiment of the device is used for intercepting flood formed by rainstorm from entering an underground garage, and is installed in a water blocking ditch at the entrance of the garage as shown in figures 2 and 3, a water blocking plate and a bearing wall support load passing through vehicles, and a communication hole transmits water pressure strongly. The whole water blocking device is made of stainless materials such as hard aluminum alloy, anti-skid grains are cut on the surface of the water blocking plate or a hard rubber buffer cushion layer is added on the surface of the water blocking plate, a rubber cushion is used at the sealing position, the rotating shaft and the supporting part are stressed greatly, and the water blocking device is made of stainless alloy steel materials. The size of the water retaining device can be designed to be balanced according to the height of the water retaining device, the strength of the selected material and the weight of the selected material. The stress is shown in figure 4 when the device is started, the water pressure F2 does not generate moment, the water pressure F1 is working force, the higher the water level is, the larger F1 and F3 are, when a certain water level is reached, the gravity is overcome, and the device is started.

When an emergency vehicle enters the garage, the water baffle can be directly rolled to enter, part of water enters the garage at the moment, and the water baffle can automatically stand to keep water after the vehicle passes through; when the emergency vehicle goes out of the garage, the water baffle needs to be manually stepped down, and the water baffle can automatically stand after the vehicle passes through the garage to keep water. If the height of the water baffle is larger than that of the chassis of the vehicle, the water baffle needs to be manually stepped down to pass through the vehicle when the vehicle enters or exits the garage.
