Description

Technical Field

[0001] The utility model relates to the technical field of elevator protection, in particular to a water inlet prevention structure for an elevator shaft. Background Art

[0002] With the popularization of high-rise buildings, the application of elevators has become more and more common. At present, elevators are installed in such a way that elevator tracks and counterweight tracks are installed on the shaft wall of the elevator shaft, and an elevator machine room is arranged at the top of the shaft to drive the elevator to rise and fall along the tracks. In addition, elevator landing doors are also installed on the shaft wall of the elevator shaft for people to enter and exit the elevator.

[0003] Chinese patent with the publication number CN214527557U discloses a water inlet prevention structure for an elevator shaft, which includes a fixed seat installed on the ground outside the elevator landing door. A receiving groove is opened at the top of the fixed seat, and a net plate is covered on the receiving groove; a water-absorbing expansion strip is filled in the receiving groove, and the water-absorbing expansion strip is connected to the net plate;

[0004] For the above-mentioned disclosed technology, the existing method absorbs water through the receiving groove and the water-absorbing expansion strip inside the receiving groove. When the water-absorbing expansion strip is full of water, it expands. When a rider steps on its upper part, the water in the water-absorbing expansion strip will be squeezed out, which is not convenient for draining water.

[0005] Therefore, a water inlet prevention structure for an elevator shaft is proposed. Content of the Utility Model

[0006] The purpose of the utility model is to provide a water inlet prevention structure for an elevator shaft to solve the problems raised in the above background art.

[0008] A water inlet prevention structure for an elevator shaft includes an elevator shaft. An elevator opening is provided on the surface of the elevator shaft. An electromagnetic door is arranged inside the elevator shaft. A water collecting box assembly is inserted at the bottom of the elevator opening. A first net plate is fixedly installed on the inner wall of the water collecting box assembly. A water-absorbing sponge and an arc-shaped spring steel plate are fixedly installed on the top surface of the first net plate. The top end of the arc-shaped spring steel plate is fixedly installed with a second net plate.

[0009] Further, the water collecting box assembly includes a box body. The box body is inserted at the bottom of the elevator opening. Drainage ports are arranged on both side walls of the box body, and valves are embedded on the surfaces of the drainage ports. A handle is fixedly installed on the top surface of the box body. Limit bumps are fixedly installed on both inner side walls of the box body.

[0010] Further, a water absorption channel is opened on the front side wall of the box body, and a plug body is inserted at the top end of the water absorption channel.

[0011] Further, the top surface of the box body and the bottom surface of the elevator entrance are correspondingly arranged, and the handle is arranged in a fitting manner on both sides of the elevator entrance.

[0012] Further, the second mesh plate is movably inserted inside the box body, and the bottom surface of the second mesh plate and the top surface of the first mesh plate are arranged in a fitting manner with the upper and lower ends of the water-absorbing sponge.

[0015] Through the water-absorbing sponge between the first mesh plate and the second mesh plate on the inner wall of the water collecting box assembly, it is possible to prevent the water in the elevator entrance from flowing into the elevator shaft. The water-absorbing sponge is used to absorb the water. After absorption, when taking the elevator and entering the elevator through the elevator entrance, when stepping on the top surface of the second mesh plate, the second mesh plate moves vertically downward inside the water collecting box assembly, compressing the water-absorbing sponge and the arc-shaped spring steel plates. By squeezing the water-absorbing sponge, the water in the water-absorbing sponge is extruded and discharged into the water collecting box assembly. Through the water collecting box assembly, the water is collected, and by lifting the water collecting box assembly, it is convenient to discharge the water in the water collecting box assembly;

[0016] By opening the plug at the top of the water absorption channel, inserting the syringe into the top of the water absorption channel opened on the front side wall of the box body, and extracting the water in the box body through the syringe via the water absorption channel, it is convenient to discharge the water in the box body, so that the water in the box body can be discharged without removing the box body.
