Abstract
Description
Technical Field
[0001] This utility model relates to the field of flood protection technology, and in particular to a water conservancy flood control and flood prevention barrier device. Background Technology
[0002] With the continuous improvement of living standards, people's demand for electricity is increasing, leading to a significant increase in the number of hydropower facilities. Hydropower stations typically equip themselves with a large number of maintenance vehicles for facility maintenance, which are usually parked in underground parking garages. However, due to their low-lying location, underground parking garages are prone to flooding during the rainy season, causing considerable inconvenience to car owners. Therefore, a drainage ditch is usually dug on the entrance ramp of the underground parking garage to discharge rainwater. However, when rainfall is excessive, the drainage capacity of the ditch may be insufficient, requiring the use of flood control sandbags to form a barrier at the entrance ramp of the underground parking garage to prevent rainwater from entering the garage. However, flood control sandbags require manual handling during use, and workers need to remove them after the rainy season, which is not only labor-intensive but also time-consuming, causing vehicles to be unable to use the underground parking garage normally during that period. Utility Model Content
[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a water conservancy flood control and flood prevention barrier device.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] Design a water conservancy flood control and flood prevention barrier device, including a drainage ditch cover plate installed on a drainage ditch. The drainage ditch cover plate has multiple through slots. Guide grooves are formed on both sides of the inner side of the slots. A shaft pin is slidably fitted in the guide groove. A connecting plate is fixedly connected to the surface of the shaft pin. A connecting rod is fixedly connected to the side wall of the connecting plate. Connecting parts are rotatably installed at both ends of the connecting rod. A baffle plate is vertically fixed to the bottom surface of the drainage ditch cover plate. The density of the baffle plate is less than that of water.
[0006] Preferably, a reflective strip is affixed to the surface of the connecting plate.
[0007] Preferably, the drainage ditch cover is provided with multiple drainage outlets to allow water to pass through.
[0008] Preferably, the baffle is provided with a control structure to control the raising and lowering of the baffle according to the water level in the drainage ditch.
[0009] Preferably, the control structure includes a wedge-shaped slider, the baffle surface is provided with a plurality of blind holes, the slider is slidably fitted in the blind holes, and a spring is provided on the inner wall of the blind holes to apply elastic force to the slider.
[0010] Preferably, a wedge-shaped limiting block is fixed to the inner wall of the drainage ditch to limit the slider.
[0011] This utility model proposes a water conservancy flood control and drainage barrier device, the beneficial effects of which are as follows: During heavy rain, rainwater enters the drainage ditch through the channel and drain outlet for discharge. If the rainfall is too heavy and drainage is insufficient, the water level in the drainage ditch will continue to rise. When the water level reaches the slider position, the water pressure causes the slider to retract into the blind hole, releasing the restriction of the limiting block on the baffle. Under the action of buoyancy, the baffle drives the drainage ditch cover plate to move upward, forming a barrier to prevent rainwater from entering the ramp. Simultaneously, the upward movement of the drainage ditch cover plate, through the cooperation of the guide groove and the shaft pin, causes the connecting plate to stand upright. The reflective strip reflects the headlights of vehicles at night, warning drivers to avoid collisions and water level hazards. After the rain stops, the device resets under the action of gravity and resumes normal operation.
[0012] This device utilizes the water pressure and buoyancy generated by the rise in water level to complete the barrier and warning actions without the need for electricity. It is energy-saving and environmentally friendly. The barrier physically blocks rainwater intrusion, and the reflective strip provides safety warnings, improving the safety of the parking lot in bad weather. It automatically resets after the rain stops, without the need for manual intervention. This not only reduces labor costs but also enables the underground parking garage to resume normal use in a timely manner. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Reference Figure 1 and Figure 2 A water conservancy flood control and flood prevention barrier device includes a drainage ditch cover plate 2, with multiple slots 3 extending through the drainage ditch cover plate 2. Guide grooves 5 are provided on the inner side walls of the slots 3. A shaft pin 9 is slidably fitted inside the guide groove 5. A connecting plate 8 is fixedly connected to the surface of the shaft pin 9. A connecting rod 7 is fixedly connected to the side wall of the connecting plate 8. Connecting parts 6 are rotatably installed on both ends of the connecting rod 7. A baffle 11 is vertically fixed to the bottom surface of the drainage ditch cover plate 2. The density of the baffle 11 is less than that of water. A reflective strip 10 is pasted on the surface of the connecting plate 8. Multiple drainage outlets 4 are provided on the drainage ditch cover plate 2 to allow water to pass through.
[0022] The drainage ditch cover 2 is installed in the drainage ditch 1 at the entrance ramp of the underground parking lot. The connector 6 is fixed to the drainage ditch 1 with screws. Under normal conditions, the drainage ditch cover 2 and the connecting plate 8 form a protective grid for the drainage ditch 1 to prevent external garbage from falling into the drainage ditch 1.
[0023] During heavy rain, rainwater enters the drainage ditch 1 through the trough 3 and the drain outlet 4 for discharge. If the rainfall is too heavy and the drainage ditch 1 has insufficient discharge capacity, the water level in the drainage ditch 1 will continue to rise. Since the density of the baffle 11 is less than that of water, under the buoyancy of the rainwater in the drainage ditch 1, the baffle 11 will drive the drainage ditch cover 2 to move upward. After the baffle 11 floats up, it will form a barrier at the ramp to prevent rainwater from entering the entrance ramp. After the drainage ditch cover 2 moves upward, it will drive the connecting plate 8 to stand up through the cooperation of the guide groove 5 and the shaft pin 9, so that the reflective strip 10 on the connecting plate 8 faces the vehicles entering the parking lot. At night, the reflected light formed by the vehicle headlights shining on the standing reflective strip 10 will warn the driver. This can not only prevent the vehicle from hitting the baffle 11, but also remind the driver that the water level is dangerous and it is not recommended to enter the parking lot.
[0024] like Figures 2-6As shown, the baffle 11 is provided with a control structure to control the raising and lowering of the baffle 11 according to the water level in the drainage ditch 1. The control structure includes a wedge-shaped slider 14. Multiple blind holes 12 are vertically opened on the surface of the baffle 11. The slider 14 is slidably fitted in the blind holes 12. A spring 13 is provided on the inner wall of the blind hole 12 to apply elastic force to the slider 14. A wedge-shaped limiting block 15 is fixed to the inner wall of the drainage ditch 1 to limit the slider 14.
[0025] When the water level in the drainage ditch 1 reaches the position of the slider 14, the slider 14 retracts into the blind hole 12 under the action of water pressure. After the slider 14 retracts into the blind hole 12, the restriction of the limit block 15 on the baffle 11 is released. At this time, the baffle 11 moves upward under the action of buoyancy.
[0026] Working principle:
[0027] During heavy rain, rainwater enters the drainage ditch 1 from the inlet 3 and outlet 4 for discharge. If the rainfall is too heavy and the drainage ditch 1 has insufficient discharge capacity, the water level in the drainage ditch 1 will continue to rise.
[0028] When the water level in the drainage ditch 1 reaches the position of the slider 14, the slider 14 retracts into the blind hole 12 under the action of water pressure. After the slider 14 retracts into the blind hole 12, the restriction of the limit block 15 on the baffle 11 is released. At this time, the baffle 11 moves upward under the action of buoyancy.
[0029] After the baffle 11 floats up, it will form a barrier at the ramp to prevent rainwater from entering the entrance ramp. After the drainage ditch cover 2 moves up, it will drive the connecting plate 8 to stand up through the cooperation of the guide groove 5 and the shaft pin 9, so that the reflective strip 10 on the connecting plate 8 faces the vehicles entering the parking lot. At night, the reflected light formed by the vehicle headlights shining on the standing reflective strip 10 will warn the driver. It can not only prevent the vehicle from hitting the baffle 11, but also remind the driver that the water level is dangerous and it is not recommended for the vehicle to enter the parking lot.
[0030] After the rain stops, the drainage ditch cover 2 and baffle 11 will be reset under the action of gravity to restore the normal use function of the underground garage in a timely manner.
[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
