Description

Technical Field

[0001] This utility model relates to the field of subway station technology, and in particular to a water-blocking device for subway stations. Background Technology

[0002] Subways are high-speed, high-capacity, electrically powered rail transit systems built in cities. In the construction of some subway station entrances, the terrain is low-lying and in low-lying areas. Once there is excessive rainfall, rainwater will flow back into the subway station.

[0003] Currently, subway station entrances and exits mostly use drainage systems such as sump pits and drainage pumps to block water from the subway. In case of heavy rain, staff will use flood barriers, ordinary sandbags, and water-absorbing and expanding sandbags to seal the entrances and exits to prevent rainwater backflow. However, most of the existing flood control devices are placed indoors in the subway and need to be manually moved to the subway entrance for water blocking when needed. The subsequent cleaning is complicated and the management cost is high.

[0004] Chinese Patent Publication No. CN213653352U discloses a hydraulic lifting baffle device for preventing rainwater backflow in subways, comprising a hydraulic lifting chamber constructed below the ground level of the subway entrance / exit; a baffle lifting channel constructed below the ground level of the subway entrance / exit and located above the hydraulic lifting chamber, the upper end of the baffle lifting channel being flush with the ground level of the subway entrance / exit, and its lower end communicating with the hydraulic lifting chamber; a baffle slidably disposed within the baffle lifting channel; and a hydraulic drive mechanism installed within the hydraulic lifting chamber and connected to the baffle for driving the baffle to reciprocate up and down along the baffle lifting channel.

[0005] The aforementioned patent uses a water barrier as a structure to prevent rainwater from flowing back into the subway entrance. However, the following problems exist: the water barrier only has the function of blocking water and does not have the function of diverting water. When the rain is too heavy, rainwater accumulates in front of the water barrier, which puts a large load on the water barrier and creates a water accumulation area, which will cause inconvenience to passengers entering. Utility Model Content

[0006] The purpose of this utility model is to overcome the above-mentioned problems existing in the prior art and to provide a water-blocking device for subway stations.

[0007] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0008] A subway station water-blocking device includes a rectangular box-shaped mounting groove with an open top and a hollow water-blocking mechanism. A telescopic cylinder is installed in the mounting groove, and the water-blocking mechanism is installed on the top of the piston rod of the telescopic cylinder and inserted into the mounting groove. The front of the water-blocking mechanism has several water inlet holes, and hollow sealing strips are installed on the left and right sides of the water-blocking mechanism. Multiple hollow sealing rings are installed at the bottom of the water-blocking mechanism, and the hollow sealing rings are sandwiched between the mounting groove and the water-blocking mechanism. A water collection trough communicating with the mounting groove is provided at the bottom of the mounting groove, and a drain pipe communicating with the water collection trough is provided at one end of the water collection trough.

[0009] The water-blocking mechanism includes a rectangular sealing ring mounting ring, two symmetrical sealing strip mounting seats, and a rectangular top plate. A front water-blocking plate extending upwards is provided at the front of the sealing ring mounting ring, and a rear water-blocking plate extending upwards is provided at the rear of the sealing ring mounting ring. The rear water-blocking plate is parallel to the front water-blocking plate. Multiple parallel reinforcing plates are fixedly connected between the rear and front water-blocking plates. The top plate is connected to the top of the reinforcing plates with screws. The two sealing strip mounting seats are respectively fixed between the two sides of the front and rear water-blocking plates. A transverse partition is fixedly connected to the sealing ring mounting ring below the sealing strip mounting seats.

[0010] The water inlet is located on the front baffle plate.

[0011] Each of the sealing strip mounting seats is provided with at least two sealing strip mounting slots, and a hollow sealing strip is installed in each sealing strip mounting slot.

[0012] The top of the left and right inner sides of the mounting groove is provided with ramps to facilitate the hollow sealing strip sliding into the mounting groove.

[0013] The hollow sealing strip contains a plurality of uniformly distributed compression springs, the central axis of which is perpendicular to the left and right sides of the water-blocking mechanism.

[0014] The beneficial effects of this utility model are: when rainwater tends to flow back into the subway entrance, the telescopic cylinder is extended to raise the water-blocking mechanism between the walls on both sides of the subway entrance. The rainwater flows into the installation groove through the water inlet at the front of the water-blocking mechanism, and then collects in the water collection trough and is discharged from the drain pipe. On the one hand, it prevents rainwater from flowing back into the subway entrance, and on the other hand, it guides and discharges the rainwater. Attached Figure Description

[0029] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] like Figures 1 to 12 As shown, a subway station water-blocking device includes a rectangular box-shaped mounting groove 1 with an open top and a hollow water-blocking mechanism 2. A telescopic cylinder 3 is installed in the mounting groove 1, and the water-blocking mechanism 2 is installed on the top of the piston rod of the telescopic cylinder 3 and inserted into the mounting groove 1. The mounting groove 1 is pre-embedded in the ground 100 of the subway entrance, so that the water-blocking mechanism 2 is located between the walls 200 on both sides of the subway entrance.

[0031] The front of the water-blocking mechanism 2 has several water inlet holes 221. Hollow sealing strips 4 are installed on the left and right sides of the water-blocking mechanism 2 respectively. Multiple hollow sealing rings 5 ​​are installed at the bottom of the water-blocking mechanism 2. The hollow sealing rings 5 ​​are sandwiched between the mounting groove 1 and the water-blocking mechanism 2.

[0032] When the water-blocking mechanism 2 is extended and driven upward by the telescopic cylinder 3, the hollow sealing strips 4 installed on the left and right sides of the water-blocking mechanism 2 abut against the walls 200 on both sides of the subway entrance, and the hollow sealing strips 4 play a sealing role between the water-blocking mechanism 2 and the walls 200; the hollow sealing rings 5 ​​play a sealing role between the mounting groove 1 and the water-blocking mechanism 2.

[0033] The bottom of the mounting groove 1 is provided with a water collection trough 6 connected to the mounting groove 1, and a drain pipe 7 connected to the water collection trough 6 is provided at one end of the water collection trough 6.

[0034] The water-blocking mechanism 2 includes a rectangular sealing ring mounting ring 21, two symmetrical sealing strip mounting seats 26, and a rectangular top plate 25. The front part of the sealing ring mounting ring 21 is provided with an upwardly extending front water baffle 22, and a water inlet 221 is opened on the front water baffle 22. The rear part of the sealing ring mounting ring 21 is provided with an upwardly extending rear water baffle 23, which is parallel to the front water baffle 22. Multiple parallel reinforcing plates 24 are fixed between the rear water baffle 23 and the front water baffle 22. The top plate 25 is connected to the top of the reinforcing plates 24 with screws. The two sealing strip mounting seats 26 are respectively fixed between the two sides of the front water baffle 22 and the rear water baffle 23. A transverse partition 27 is fixed in the sealing ring mounting ring 21 below the sealing strip mounting seats 26.

[0035] The specific installation structure of the hollow sealing ring 5 and the hollow sealing strip 4 is as follows: multiple parallel sealing ring mounting grooves 211 are provided on the outer side of the sealing ring mounting ring 21, and the hollow sealing ring 5 is installed in the sealing ring mounting groove 211; each sealing strip mounting seat 26 is provided with at least two sealing strip mounting grooves 261, and one hollow sealing strip 4 is installed in each sealing strip mounting groove 261.

[0036] Multiple evenly distributed compression springs 8 are installed in the cavity of the hollow sealing strip 4. The central axis of the compression springs 8 is perpendicular to the left and right sides of the water-blocking mechanism 2. When the water-blocking mechanism 2 is extended and driven upward by the telescopic cylinder 3, the restoring force of the compression springs 8 increases the pressure between the hollow sealing strip 4 and the wall, thereby improving the sealing performance between the hollow sealing strip 4 and the wall 200.

[0037] The top of the left and right inner sides of the mounting groove 1 is provided with ramps 11 to facilitate the hollow sealing strip 4 to slide into the mounting groove 1.

[0038] When rainwater tends to flow back into the subway entrance, the telescopic cylinder extends to raise the water-blocking mechanism between the walls on both sides of the subway entrance. Rainwater flows into the installation groove through the water inlet at the front of the water-blocking mechanism, and then collects in the water collection trough and is discharged from the drain pipe. This not only prevents rainwater from flowing back into the subway entrance, but also guides and discharges the rainwater.
