Abstract
Description
Technical Field
[0001] The utility model relates to a liftable flood prevention and water retaining device for an underground garage. Background Art
[0002] Nowadays, most urban communities have underground garages. The entrances to underground garages are usually on the street. When there is a long period of heavy rain, the streets are flooded and the water can easily flow back into the underground garage through the garage entrance, causing property damage. Underground garages require flood control and water retaining devices.
[0003] At present, some communities have set up a simple baffle at the entrance of the underground garage. This flood prevention and water retaining device can deal with light rain. However, when encountering heavy rain, the baffle cannot withstand the impact of the flood and is easily washed away. Utility Model Content
[0004] The technical problem solved by the utility model is to provide a liftable flood prevention and water retaining device for an underground garage, comprising two columns, the two columns are arranged oppositely on the ground of the underground garage entrance, and are respectively fixedly and sealedly connected to the walls on both sides of the underground garage entrance; the bottoms of the two columns are connected by a groove, a cover plate is arranged on the groove, and the upper surface of the cover plate is flush with the ground; the columns are hollow, and the opposite sides of the two columns are open; a steel wire protection net is arranged in the groove; a protection net column is arranged in the column; both ends of the steel wire protection net are sleeved on the protection net in the two columns through rings The steel wire protection net is arranged on the column; a traction rope is connected to the top of the steel wire protection net, one end of the traction rope is fixedly connected to the upper inner wall of a column, and the other end is connected to the motor through a pulley, the pulley is fixed to the upper inner wall of another column, and the motor is fixed to the inner wall of another column; a sealing net is arranged in parallel with the steel wire protection net, the sealing net is arranged on the outside of the underground garage entrance, and the steel wire protection net is arranged on the inside of the underground garage entrance, and the sealing net is made of rectangular waterproof cloth; the long sides of the bottom of the sealing net are respectively sealed and connected to the inner walls of the two columns and the inner wall of the groove; the long sides of the top of the sealing net are connected to the traction rope.
[0005] The cross section of the column is rectangular.
[0006] The protective net column is cylindrical and made of steel pipe.
[0007] The sealing net is sealed and connected to the inner wall of the column and the inner wall of the groove through a flat steel sheet.
[0008] The flat steel sheet is fixed to the inner wall of the column and the inner wall of the groove by threaded fasteners.
[0009] Side cover plates are arranged on opposite sides of the two columns.
[0010] With the structure of the utility model, a steel wire protection net and a sealing net are arranged in parallel at the entrance of the underground garage, the steel wire protection net and the sealing net are respectively connected to two columns and the groove, and the upper parts of the steel wire protection net and the sealing net are connected to the traction rope. When in use, the side cover plates of the two columns and the cover plate of the groove are opened, and the motor is started to drive the traction rope to pull up the steel wire protection net and the sealing net to form a protective wall, which can prevent floods from entering the underground garage. Since the sealing net is sealed and connected to the two columns and the groove respectively, the sealing net can block water in the front without leakage; since there is a steel wire protection net behind the sealing net, it can strongly support the sealing net and prevent the sealing net from being washed away by the flood. When not in use, the motor drives the traction rope to put down the steel wire protection net and the sealing net, and automatically gathers and places them in the two columns and the groove, and then covers the cover.
[0011] The utility model has the advantages of simple structure, safety, reliability, liftability and convenience in use. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 3 It is a top view schematic diagram of the utility model. DETAILED DESCRIPTION
[0015] The utility model is described in detail below with reference to the accompanying drawings and specific embodiments:
[0016] like Figure 1 , Figure 2 , Figure 3 As shown, the utility model of the underground garage liftable flood prevention and water retaining device comprises two columns 1. The two columns are arranged on the ground of the underground garage entrance relatively, and are respectively fixedly and sealedly connected with the walls on both sides of the underground garage entrance.
[0017] The bottoms of the two columns are connected by a groove 4. A cover plate is provided on the groove, and the upper surface of the cover plate is flush with the ground.
[0018] The columns are hollow and the opposite sides of the two columns are open.
[0019] A steel wire protection net 3 is arranged in the groove. The steel wire protection net is placed in the groove after being folded.
[0020] A protective net column 2 is arranged in the column. The two ends of the steel wire protective net are sleeved on the protective net columns in the two columns through sleeve rings.
[0021] A traction rope is connected to the top of the wire protection net. One end of the traction rope is fixedly connected to the upper inner wall of a column, and the other end is connected to the motor through a pulley. The pulley is fixed to the upper inner wall of another column, and the motor is fixed to the inner wall of another column.
[0022] A sealing net 5 is arranged parallel to the steel wire protection net. The sealing net is arranged outside the entrance of the underground garage, and the steel wire protection net is arranged inside the entrance of the underground garage. The sealing net is made of rectangular waterproof cloth. The long sides of the bottom of the sealing net are respectively sealed and connected to the inner walls of the two columns and the inner wall of the groove. The long side of the top of the sealing net is connected to the traction rope.
[0023] The cross section of the column is rectangular.
[0024] The protective net column is cylindrical and made of steel pipe.
[0025] The sealing net is sealed and connected with the inner wall of the column and the inner wall of the groove through the flat steel sheet 6. The flat steel sheet is fixed to the inner wall of the column and the inner wall of the groove by threaded fasteners.
[0026] Side covers are provided on the opposite sides of the two columns. Covers are provided on the trenches. When used for flood prevention, the covers are opened. Under normal circumstances, the covers are closed and traffic is allowed as usual.
[0027] The two columns can be set up at the appropriate positions on both sides of the entrance and exit of the underground garage. A foundation pit with a diameter of 1.5 meters and a depth of 2 to 3 meters can be dug, and a steel mesh cage can be embedded to expose 4 threaded steel bars with a diameter of 50mm. Then cement is poured. After the cement solidifies, a customized 20mm thick C-shaped channel steel is installed on the threaded steel. The channel steel is 2 to 3 meters high, with 20mm thick steel plates at both ends, and one end is connected to the anchor bolt. A cylindrical seamless steel pipe with a diameter of 75mm is inserted in the middle, and the steel pipe is firmly welded to the steel plates at both ends of the C-shaped channel steel.
[0028] Groove setting: open a groove in the middle of two columns. Clamp into the U-shaped steel groove, and the movable manhole cover can be embedded outside the U-shaped steel opening. Weld the C-shaped channel steels on both sides and the U-shaped steel in the middle into one, forming a groove. Shrink the waterproof cloth and wire mesh and put them in. Connect the wire mesh to the bottom of the U-shaped steel groove. The two ends of the wire mesh are tied to the columns in the C-shaped channel steels on both sides, and can be raised and lowered to form a whole open wire mesh. In addition, a waterproof cloth is installed right in front of the wire mesh, and one side of the waterproof cloth is fixed to the inner side of the C-shaped channel steels on both sides and the inner side of the U-shaped channel steels with screws.
