Description

Technical Field

[0001] This invention belongs to the field of flood control facilities for underground parking garages, and in particular relates to a water-blocking facility at the entrance and exit of an urban underground parking garage. Background Technology

[0002] With the rapid pace of urbanization, urban flood control and drainage problems during heavy rains are becoming increasingly severe. The frequent occurrence of submerged cars in urban underground parking garages exposes the inadequacy of underground flood control and drainage systems in various regions, highlighting outdated and flawed flood prevention mechanisms. This hinders accurate, timely, and effective responses to emergencies, resulting in significant social and property losses. Traditional flood control measures at the entrances and exits of urban underground parking garages involve manually moving pre-placed sandbags or multiple water-blocking barriers. These traditional methods are not only resource-intensive but also require constant monitoring and manual adjustment, making them inconvenient. While some companies have developed flood control measures, these remain complex, time-consuming, labor-intensive, and have limited practicality, leaving room for improvement. Summary of the Invention

[0003] The purpose of this invention is to provide a water-blocking facility at the entrance and exit of an urban underground parking garage to overcome the shortcomings of the prior art.

[0004] To achieve the above-mentioned objectives, the technical solution adopted by this invention is as follows:

[0005] A water-blocking facility at the entrance and exit of an urban underground parking garage includes: a pit, a sealing partition installed inside the pit, the sealing partition dividing the pit into an airbag chamber and a drainage chamber, a rubber airbag sealed at the top of the airbag chamber, a pneumatic lifting mechanism fixedly installed at the bottom of the airbag chamber, both the airbag chamber and the pneumatic lifting mechanism being connected to an external air pump, a rain-leaking manhole cover detachably installed at the top of the drainage chamber, and the bottom of the drainage chamber being connected to a sewer pipe.

[0006] Preferably, the top of the airbag cavity is provided with a groove, and a cover is detachably installed in the groove.

[0007] Preferably, the pneumatic lifting mechanism includes: a pressure chamber, with slides symmetrically arranged at both ends of the pressure chamber, and movable blocks slidably arranged in each of the two slides. The front and rear ends of the two movable blocks are hinged to upper and lower connecting rods, respectively. An upper sliding rod and a lower sliding rod are also slidably arranged at the top center and bottom center of the pressure chamber, respectively. An arc-shaped plate is fixed to the top of the upper sliding rod, and a base is fixed to the bottom of the lower sliding rod. The base is fixed to the bottom wall of the air bladder cavity. All four upper connecting rods are hinged to the bottom of the arc-shaped plate, and all four lower connecting rods are hinged to the top of the base.

[0008] Preferably, slide rails are provided on the side wall of the pit that contacts the slide rail and on the sealing partition, and the outer wall of the slide rail slides in cooperation with the slide rail.

[0009] Preferably, air holes are provided on the side walls of both the airbag cavity and the air pressure chamber, and the air holes are used to connect to an external air pump.

[0010] Preferably, the drainage chamber is located at one end near the underground garage.

[0011] Preferably, the rubber airbag is coated with a wear-resistant coating.

[0012] Preferably, the height of the rubber airbag is 5-10cm during operation.

[0013] The water-blocking device for the entrance and exit of an urban underground parking garage provided by this invention has the following advantages compared with the prior art:

[0014] This invention involves excavating a pit at the entrance of an underground parking garage and installing a rubber airbag and a pneumatic lifting mechanism within it. In sunny weather, the airbag and lifting mechanism can be stored within the airbag cavity, with a cap placed on top to ensure normal vehicle access and maintain aesthetics. In rainy weather, the cap can be manually removed, and an external air pump can inflate the airbag cavity and lifting mechanism to form a barrier. The pneumatic lifting mechanism also provides shock absorption, ensuring uninterrupted vehicle access even when the airbag is in operation, making it convenient and quick. Furthermore, a small amount of rainwater inevitably seeps in when vehicles drive over it; a drainage chamber located behind the airbag cavity perfectly solves this problem, demonstrating high practicality.

Detailed Implementation

[0019] The technical solution of the present invention will be further described below with reference to the accompanying drawings and embodiments:

[0020] refer to Figure 1-2 As shown, this invention provides a water-blocking facility for the entrance and exit of an urban underground parking garage, comprising: a foundation pit, within which a sealing partition 1 is installed, dividing the foundation pit into an airbag chamber 2 and a drainage chamber 3; a rubber airbag 4 is sealed at the top of the airbag chamber 2, and a pneumatic lifting mechanism 5 is fixedly installed at the bottom of the airbag chamber 2; both the airbag chamber 2 and the pneumatic lifting mechanism 5 are connected to an external air pump; a rain-leaking manhole cover 6 is detachably installed at the top of the drainage chamber 3, and the bottom of the drainage chamber 3 is connected to a sewer pipe 7. A slot is formed at the top of the airbag chamber 2, and a cover 8 is detachably installed within the slot. This invention, by excavating a foundation pit at the entrance and exit of the underground parking garage and installing a rubber airbag 4 and a pneumatic lifting mechanism 5 within the pit, allows the rubber airbag 4 and the pneumatic lifting mechanism 5 to be stored in the airbag chamber 2 on sunny days, with the cover 8 placed on top, thus ensuring normal vehicle entry and exit and maintaining aesthetics.

[0021] In a preferred embodiment, the pneumatic lifting mechanism 5 includes: a pressure chamber 9, with slide rails 10 symmetrically arranged at both ends of the pressure chamber 9. Moving blocks 11 are slidably arranged within each of the two slide rails 10. Upper connecting rods 12 and lower connecting rods 13 are hinged to the front and rear ends of each of the two moving blocks 11. An upper sliding rod 14 and a lower sliding rod 15 are slidably arranged at the top center and bottom center of the pressure chamber 9, respectively. An arc-shaped plate 16 is fixed to the top of the upper sliding rod 14, and a base 17 is fixed to the bottom end of the lower sliding rod 15. The base 17 is fixed to the bottom wall of the airbag cavity 2. All four upper connecting rods 12 are hinged to the bottom end of the arc-shaped plate 16, and all four lower connecting rods 13 are hinged to the top end of the base 17. Slide rails are provided on the sidewall of the pit that contacts the slide rails 10 and on the sealing partition 1. The outer wall of the slide rails 10 slides in cooperation with the slide rails. Both the air bladder cavity 2 and the air pressure chamber 9 have air holes 18 on their side walls, which are used to connect to an external air pump. During rainy weather, property management personnel remove the cover 8 and inflate the airbag cavity 2 and pressure chamber 9 using an external air pump. As the air pressure in pressure chamber 9 increases, it pushes the upper sliding rod 14 upward, while the lower sliding rod 15, fixed to the base 17, remains in the same position. Therefore, the slide rail 10 moves upward along the slide rail of the pit sidewall and the sealing partition 1, ultimately achieving the lifting effect of the arc plate 16 on the rubber airbag 4. At the same time, the air pressure in the airbag cavity 2 also increases, causing the rubber airbag 4 to gradually expand. This prevents the pressure in the airbag cavity 2 from decreasing due to the pneumatic lifting mechanism 5 pushing the rubber airbag 4 upward, thus preventing the formation of grooves around the rubber airbag 4 and the accumulation of rainwater. When the weather is sunny, property management personnel can use an external air pump to remove the air from the airbag cavity 2 and pressure chamber 9, thereby resetting the rubber airbag 4 and the pneumatic lifting mechanism 5. Finally, the cover 8 is replaced.

[0022] In a preferred embodiment, the drainage chamber 3 is located at one end near the underground garage. The rubber airbag 4 is coated with a wear-resistant coating. During operation, the height of the rubber airbag 4 is 5-10cm. Preferably, the height of the rubber airbag 4 should be between the average height of the speed bump and the car chassis, so that it does not affect the normal entry and exit of vehicles in rainy weather. However, when a vehicle runs over it, a small amount of rainwater will inevitably enter. The drainage chamber 3 located behind the airbag chamber 2 perfectly solves this problem and is highly practical.
