Description

Technical Field

[0001] The utility model relates to the technical field of subway passage anti-flooding doors, in particular to a hydraulic anti-flooding door for a subway connecting passage. Background Art

[0002] Subway entrances and exits are typically below ground level. Therefore, during heavy rain, rainwater easily accumulates at the entrances, causing backflow into the station, which in turn can damage the interior of the station. Therefore, water retaining structures are typically installed at subway entrances and exits to prevent backflow. Subway passageway flooding prevention doors are a key component in addressing this technical problem. However, existing subway passageway flooding prevention doors are mostly driven by a single motor or hydraulic rod. These doors are generally heavy, and the motor and hydraulic rod bear a relatively heavy load.

[0003] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a hydraulic flood-proof door for subway connecting passages is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a hydraulic flood prevention door for a subway connecting passage to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a hydraulic flood-proof door for a subway connecting passage, comprising a foundation and a rail fixedly connected to the upper surface of the foundation, a sewer being arranged inside the left side of the foundation, a water flow trough being provided inside the upper surface of the foundation connected to the sewer, a gate receiving groove being provided inside the right side of the foundation, a flood-proof door being rotatably connected inside the gate receiving groove, and a transmission mechanism being provided outside the flood-proof door.

[0006] Preferably, the transmission mechanism includes a hydraulic rod rotatably connected to the lower surface of the flood-proof door, a bracket is fixedly connected to the right side of the upper surface of the foundation, the upper end of the bracket is rotatably connected to an auxiliary roller, a counterweight block is provided on the right side of the bracket, and the counterweight block and the flood-proof door are connected by a steel cable.

[0007] Preferably, a cast wall is provided on the rear surface of the foundation, and a slide rail plate is fixedly connected to the front surface of the cast wall.

[0008] Preferably, a right outer surface of the bracket is fixedly connected to a slide rail frame, and a left outer surface of the counterweight block is fixedly connected to a slider.

[0009] Preferably, a filter plate is provided at the notch on the upper surface of the water trough, and the filter plate is placed in a snap-fit ​​manner.

[0010] Preferably, a diversion groove is opened on the right side of the interior of the water trough, and the diversion groove is connected to the right outer surface of the foundation.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The utility model is equipped with a foundation, rails, sewers, water troughs, gate storage grooves, flood control doors, transmission mechanisms, hydraulic rods, brackets, auxiliary rollers, and counterweights. The hydraulic rod shortens to allow the flood control door to descend, allowing water to flow to the right side of the foundation for drainage and prevent water accumulation on the rails. During the transmission process of the transmission mechanism, the counterweights can offset the gravity of the flood control door and reduce the load on the hydraulic rods.

[0013] 2. The utility model is provided with a cast wall, a slide plate, a slide rail frame, a slider, a filter plate, and a diversion trough. The slide plate on the cast wall can play an auxiliary limiting role in the rotation of the anti-flood door, and the slide rail frame can prevent the counterweight block from swinging during the rising or falling process.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] like Figure 1-Figure 3As shown, a hydraulic flood-proof door for a subway connecting passage comprises a foundation 1 and a rail 2 fixedly connected to the upper surface of the foundation 1, a sewer 3 is provided inside the left side of the foundation 1, a water flow trough 4 is provided inside the upper surface of the foundation 1 connected to the sewer 3, a gate receiving groove 5 is provided inside the right side of the foundation 1, a flood-proof door 6 is rotatably connected inside the gate receiving groove 5, a transmission mechanism 7 is provided outside the flood-proof door 6, the transmission mechanism 7 comprises a hydraulic rod 71 rotatably connected to the lower surface of the flood-proof door 6, a bracket 72 is fixedly connected to the right side of the upper surface of the foundation 1, an auxiliary roller 73 is rotatably connected to the upper end of the bracket 72, a counterweight block 74 is provided on the right side of the bracket 72, and the counterweight block 74 and the flood-proof door 6 are connected by a steel cable.

[0021] By adopting the above technical solution, when the water flow is small, the water flow can be discharged into the sewer 3 through the water flow trough 4. When the water flow is too large and the groove diameter of the water flow trough 4 does not meet the drainage requirements, the hydraulic rod 71 can be shortened to allow the anti-flood door 6 to descend. The upper surface of the anti-flood door 6 is flush with the upper surface of the foundation 1, and the water flow can flow to the right side of the foundation 1 for drainage to prevent water accumulation on the rails 2. During the transmission process of the transmission mechanism 7, the counterweight block 74 can offset the gravity of the anti-flood door 6 and reduce the load of the hydraulic rod 71.

[0022] like Figures 1-4 As shown, a cast wall 8 is provided on the rear surface of the foundation 1 , and a slide rail plate 9 is fixedly connected to the front surface of the cast wall 8 .

[0023] Furthermore, the right outer surface of the bracket 72 is fixedly connected to the slide rail frame 10 , and the left outer surface of the counterweight block 74 is fixedly connected to the slider 11 .

[0024] Furthermore, a filter plate 12 is provided at the notch on the upper surface of the water trough 4 , and the filter plate 12 is placed in a snap-fit ​​manner.

[0025] Furthermore, a diversion groove 13 is opened on the right side of the interior of the water trough 4 , and the diversion groove 13 is connected to the right outer surface of the foundation 1 .

[0026] Working principle: When using the hydraulic flood-proof door of the subway connecting channel, first, when the water flow is small, the water can be discharged into the sewer 3 through the water flow trough 4. When the water flow is too large and the groove diameter of the water flow trough 4 does not meet the drainage requirements, the hydraulic rod 71 can be shortened to allow the flood-proof door 6 to drop. The upper surface of the flood-proof door 6 is level with the upper surface of the foundation 1, and the water can flow to the right side of the foundation 1 for drainage to prevent water accumulation on the rails 2. During the transmission process of the transmission mechanism 7, the counterweight block 74 can offset the gravity of the flood-proof door 6 and reduce the load of the hydraulic rod 71. The slide plate 9 on the cast wall 8 can assist in limiting the rotation of the flood-proof door 6. The slider 11 can slide in the slide groove on the surface of the slide frame 10 to prevent the counterweight block 74 from swinging during the rising or falling process. This is the working principle of the hydraulic flood-proof door of the subway connecting channel.
