Description

Technical Field

[0001] The utility model belongs to the technical field of garage equipment, and in particular relates to a rainproof structure for an underground garage entrance. Background Art

[0002] An underground garage refers to a building built underground for parking vehicles, which is mainly composed of parking rooms, passages, entrances and exits. Existing underground garages generally have entrances and exits on the ground. When there is large-scale rainfall, rainwater can easily flow back into the garage through the entrances and exits, causing damage to the vehicles in the garage.

[0003] A Chinese patent with publication number CN115354952A discloses a convenient rainwater backflow prevention device, which includes a main body, a sliding plate, a drive assembly and a guide assembly. The guide assembly includes two groups of vehicle guide plates. The front and rear surfaces of the upper end of the sliding plate are respectively rotatably connected to the two groups of vehicle guide plates. The above scheme adjusts the height of the sliding plate through the drive assembly, thereby driving the vehicle guide plate to rotate. The above scheme uses the adjustment of the height of the sliding plate to adjust the inclination angle of the vehicle guide plate, which can facilitate the entry and exit of vehicles when the water accumulation is not serious.

[0004] When adjusting the height of the sliding plate in the above scheme, the upper end of the vehicle guide plate moves vertically and the bottom end thereof moves horizontally. When the length of the vehicle guide plate is short, the inclination angle of the vehicle guide plate changes greatly with the change of the height of the sliding plate, which results in the above scheme having poor adaptability to vehicles with small approach angles and departure angles. When the length of the vehicle guide plate is long, a larger installation space is required, which results in the above scheme having limited applicable scenarios. Utility Model Content

[0005] The utility model aims to provide a rainproof structure for an underground garage entrance, so as to solve the problem that the above-mentioned solution has limited applicable scenarios.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A rainproof structure for an underground garage entrance comprises a road body, a movable plate, a driving assembly and a guiding assembly, wherein the road body is recessed with a water trough at the garage entrance, a drain pipe is connected to the bottom of the side wall of the water trough, a liquid level sensor is fixedly arranged in the water trough, the movable plate is vertically slidably embedded in the water trough, and the movable plate is located in the water trough away from the outdoor side, the driving assembly can drive the movable plate to move up and down, the driving assembly is electrically connected to the liquid level sensor, the guiding assembly is arranged in two groups, the two guiding assemblies are respectively arranged on both sides of the movable plate, each group of guiding assemblies respectively comprises a first guiding plate and a second guiding plate, one end of the second guiding plate is slidably sleeved on one end of the first guiding plate, the other end of the first guiding plate is rotatably connected to the top of the movable plate, and the other end of the second guide plate is rotatably connected to the road body.

[0008] The principle and effect of this technical solution:

[0009] When it rains, rainwater flows into the gutter and is discharged from the drain pipe. When the rainfall is greater than the drainage volume, rainwater accumulates in the gutter. The liquid level sensor drives the driving assembly to move the movable plate upward according to the detected water level to prevent rainwater from flowing into the garage. During the upward movement of the movable plate, the first guide plate and the second guide plate are driven to rotate, and the first guide plate slides relative to the second guide plate.

[0010] Through the above-mentioned arrangement, the movable plate can be automatically lifted when rainwater accumulates to prevent rainwater from flowing back, and at the same time, the first guide plate and the second guide plate can be driven to rotate, and the first guide plate can be made to slide relative to the second guide plate, thereby reducing the rotation angle of the first guide plate and the second guide plate as the movable plate is raised, so as to facilitate the passage of vehicles with smaller approach angles and departure angles, and at the same time reduce the size requirements for the installation space, thereby broadening the applicable scenarios of the utility model.

[0011] In the utility model, a comb tooth frame is fixedly arranged on the top of the other end of the first guide plate, and a plurality of notches cooperating with the comb tooth frame are arranged on the top of one end of the second guide plate. With the above arrangement, when a vehicle drives onto the first guide plate from the second guide plate, the bumping of the vehicle can be reduced, making it easier for the vehicle to pass.

[0012] In the utility model, the top of the other end of the first guide plate is provided with a plurality of through holes above the water tank. Through the above arrangement, rainwater can flow into the water tank through the gap between the comb frame and the notch, thereby enhancing the water diversion capability of the utility model in daily use.

[0013] In the utility model, the top of the road body is provided with grooves on the left and right sides of the water tank, and the two grooves are respectively provided with connecting rods fixedly arranged in the horizontal direction at one end away from each other, and the other end of the second guide plate is rotatably sleeved on the connecting rod. Through the above arrangement, the first guide plate and the second guide plate can be prevented from protruding from the ground when in a horizontal state, thereby ensuring the flatness of the road.

[0014] In the utility model, the bottoms of the two grooves are respectively provided with a plurality of mounting grooves, and support assemblies are respectively arranged in the mounting grooves. Each group of support assemblies includes a telescopic rod, a slider and a connecting rod. The slider is slidably embedded in the mounting groove. One end of the telescopic rod is fixedly connected to the side wall of the slider, and the other end is fixedly connected to the end wall of the mounting groove. One end of the connecting rod is rotatably connected to the slider, and the other end is rotatably connected to the bottom of one end of the first guide plate.

[0015] The principle and effect of this technical solution:

[0016] When the moving plate drives the first guide plate to rotate, the connecting rod drives the slider to move and extend the telescopic rod. When the vehicle drives onto the first guide plate and the second guide plate, the telescopic rod prevents the slider from moving in the reverse direction, so that it provides support for the first guide plate and the second guide plate, offsetting part of the force applied by the vehicle.

[0017] Through the above arrangement, deformation of the first guide plate and the second guide plate due to a large bending moment generated by the gravity of the vehicle can be avoided, thereby extending the service life of the utility model.

[0018] In the utility model, the driving assembly includes a screw and a motor. There are two screws, and the two screws are rotatably inserted in the front and rear sides of the water tank respectively. The motor is fixedly arranged above the road body and is transmission-connected with one of the screws. The motor is also electrically connected to the liquid level sensor. Connecting plates are fixedly arranged on the front and rear sides of the movable plate. The two connecting plates are respectively fitted and sleeved on the corresponding screws, and the two screws are transmission-connected through the transmission assembly.

[0019] In the utility model, the transmission assembly includes a pulley and a transmission belt. Two pulleys are provided and are respectively fixedly provided at the bottom of the screw rod. The transmission belt is wound around the two pulleys.

[0020] The principle and effect of this technical solution:

[0021] The motor drives one of the screws to rotate, and the screw drives the other screw to rotate through the pulley and the transmission belt. Since the moving plate cannot rotate with the screw, the moving plate moves up and down with the rotation of the screw.

[0022] Through the above arrangement, the purpose of driving the movable plate to move up and down is achieved.

[0023] In the utility model, a sealing strip is fixedly arranged on the top of the inner wall of the water tank away from the outside, and the movable plate slides against the sealing strip. Through the above arrangement, rainwater can be prevented from seeping into the garage through the gap between the movable plate and the water tank, thereby improving the practicality of the utility model.
