Description

Technical Field

[0001] The invention relates to the technical field of urban flood control equipment, and in particular to a water pressure self-driven flood control gate. Background Art

[0002] With the significant changes in the global climate and the frequent invasion of extreme weather events, urban flood disasters have become increasingly prominent as a major natural threat to the daily life and property safety of urban residents. Especially in summer and autumn, when vast areas of my country generally enter the rainy season, continuous rainfall or sudden rainstorms may cause serious flood disasters at any time.

[0003] In the underground spaces of some buildings, such as underground garages, power distribution rooms and other key areas, if they encounter extreme weather such as sudden heavy rains, or any minor faults or ruptures in the pipeline system, groundwater may accumulate rapidly, resulting in serious waterlogging problems. These areas are located in low-lying areas with relatively backward drainage systems. Since it is impossible to effectively drain the accumulated water in a short period of time, and it is impossible to prevent the accumulated water from entering, once the accumulated water rushes in, it often quickly evolves into a serious urban flood crisis, bringing huge impacts and threats to residents' lives, property safety and even urban operations.

[0004] Therefore, a water pressure self-driven flood control gate is proposed to solve the above problems. Summary of the invention

[0005] The present invention provides a water pressure self-driven flood control gate, which is designed to automatically start when an underground garage or underground place is swept by floods, so as to block the floods outside the underground environment and avoid the loss of underground equipment and property.

[0006] A water pressure self-driven flood control gate comprises a ground frame, a water inlet net, a sealing cavity, a support frame, a placement cavity, a right frame, a left frame, a flood control gate and a steel wire rope;

[0007] The sealed chamber is arranged at the front end below the ground frame, and the placement chamber is arranged at the rear end below the ground frame. The sealed chamber is fixed to the placement chamber through the support frame. The sealed chamber is a box structure without a cover. The water inlet net is fixedly arranged on the ground frame just above the opening of the sealed chamber. A water tank is arranged in the sealed chamber. A drainage hole is opened on the front end surface of the water tank. A sealing belt for water isolation is fixedly arranged around the bottom of the water tank. A first drainage valve is arranged at the upper part of the front end surface of the sealed chamber, and a second drainage valve is arranged at the lower part of the front end surface of the sealed chamber. The arrangement position of the first drainage valve is based on the condition that the drainage hole and the first drainage valve can be connected when the water tank is at the upper part of the sealed chamber, and the arrangement position of the second drainage valve is based on the condition that the drainage hole and the second drainage valve can be connected when the water tank is at the bottom of the sealed chamber.

[0008] The flood gate passes through the ground frame from top to bottom and is arranged in the placement cavity, and the gap between the flood gate and the ground frame is filled with a water-isolating sealing strip, and the sealing strip is fixedly arranged on the ground frame;

[0009] The right side frame is fixedly arranged on the right side of the ground frame, and the left side frame is arranged on the left side of the ground frame. Both the right side frame and the left side frame are fixedly provided with fixed pulleys. The steel wire rope is supported and guided by the fixed pulley, with one end fixed on the water tank and the other end fixed on the flood control gate.

[0010] As a further description of the above technical solution: a hydraulic drive mechanism for driving the flood control gate is fixedly provided in the placement cavity.

[0011] As a further description of the above technical solution: the hydraulic drive mechanism includes a hydraulic cylinder, a slide rail, a slider and a push rod. The hydraulic cylinder and the slide rail are fixedly arranged on the bottom surface of the inner part of the placement cavity. The slider is arranged on the slide rail and driven by the hydraulic cylinder. One end of the push rod is hinged to the slider and the other end is hinged to the flood control gate.

[0014] As a further description of the above technical solution: the first drain valve, the second drain valve, the third valve and the fourth valve are all one-way valves.

[0015] The present invention has the following beneficial effects:

[0016] The water pressure self-driven flood control gate described in the present invention relies on the gravity of accumulated water to achieve automatic opening and closing, does not require an external power source, can automatically adjust its position according to changes in water level, thereby effectively preventing the invasion of accumulated water, and is simple to manufacture, reliable in operation, and easy to manage and maintain.

[0031] The flood gate 10 passes through the ground frame 1 from top to bottom and is arranged in the placement cavity 7. The gap between the flood gate 10 and the ground frame 1 is filled with a water-proof sealing strip, and the sealing strip is fixedly arranged on the ground frame 1.

[0032] The right side frame 8 is fixedly arranged on the right side of the ground frame 1, and the left side frame 9 is arranged on the left side of the ground frame 1. Both the right side frame 8 and the left side frame 9 are fixedly provided with a fixed pulley 16.

[0038] How it works

[0039] Reference Figure 1 to Figure 5 When water accumulates, the accumulated water enters the water tank 13 in the sealed cavity 3 through the water inlet net 2. When the amount of accumulated water is small, the accumulated water can be discharged into the water channel through the drainage hole 14 of the water tank 13 and then through the first drainage valve 4. As the amount of accumulated water increases, when the increase in the amount of accumulated water is greater than the drainage amount of the first drainage valve 4, the water in the water tank 13 will accumulate, and the weight of the water tank 13 plus the accumulated water will become higher and higher. The water tank 13 moves under the action of gravity, and then the flood gate 10 at the other end of the wire rope 15 is pulled up by the wire rope 15 to block the accumulated water outside the door. When the amount of accumulated water is particularly large, the water tank 13 sinks to the bottom of the sealed cavity 3, and the flood gate 10 When the water level rises to the highest point, the drainage hole 14 is connected with the second drainage valve 5. The second drainage valve 5 and the first drainage valve 4 drain water outward at the same time, which can increase the speed of water discharge. When the amount of accumulated water discharged is greater than the speed of accumulated water, the flood control gate 10 will drop under the action of gravity. When the accumulated water is drained, the flood control gate 10 falls into the placement chamber 7 again. The above process is a self-driving transmission of a water pressure self-driven flood control gate proposed by the present invention. The water pressure self-driven flood control gate is automatically opened and closed under the gravity of accumulated water, does not require an external power source, and can automatically adjust its position according to changes in water level, thereby effectively preventing the invasion of accumulated water. It is also simple to manufacture, reliable in operation, and convenient to manage and maintain.

[0040] Reference Figure 6 to Figure 9 When the self-driving due to water accumulation fails, the flood gate 10 can be driven to open and close by the hydraulic drive mechanism in an emergency. The hydraulic cylinder 17 can push the slider 19 on the slide rail 18 to slide left and right, and then push the flood gate 10 up and down through the push rod 20. The water pressure self-driven flood gate is also provided with a hydraulic drive mechanism as a protective drive. When the self-driving due to water accumulation fails, the hydraulic drive can be driven in an emergency to complete the flood control operation. For the self-driving due to water accumulation, the hydraulic drive is equivalent to a secondary protection device, which can play a double insurance role.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
