Description

Technical Field

[0001] The invention relates to a flood prevention structure and belongs to the technical field of construction engineering. Background Art

[0002] Urban flood control is an important function in municipal engineering. Whether it is public road facilities or residential building facilities, the ability to quickly drain water in rainstorms and effectively prevent floods are important indicators for measuring the implementation function and safety of equipment. Take the underground garage in the residential area as an example. Figure 1 As shown, the existing underground garage usually has a drainage ditch 1 at the entrance 100 of the garage, and a rain grate 2 is set on the drainage ditch. When encountering heavy rain weather, the instantaneous rainfall is large, and the rainwater accumulation speed exceeds the drainage speed, it is necessary to manually build a flood control dam at the entrance of the garage, that is, to set up sandbags to block water. However, the sandbag water blocking method has many defects. First, sandbags need to be prepared at all times and need to occupy storage space; secondly, carrying sandbags consumes a lot of manpower; in addition, the manual construction of flood control dams needs to be completed before heavy rain, and most heavy rains cannot be accurately predicted. As such, various factors have caused the current flood control structure to be unable to meet people's needs. It is necessary to design a new type of flood control structure to overcome the defects in the above-mentioned prior art and achieve better flood control effects. Summary of the invention

[0003] Therefore, the purpose of the present invention is to overcome the defects in the above-mentioned prior art and provide a new type of flood prevention structure that can achieve better flood prevention effect.

[0004] In order to achieve the above-mentioned purpose, a flood control structure of the present invention includes a drainage ditch arranged outside a flood control area, a rain grate detachably provided on the drainage ditch, a water storage capsule provided in the drainage ditch, the drainage ditch is arranged horizontally, the water storage capsule is in the shape of an elongated strip and extends along the long direction of the drainage ditch; the flood control structure also includes a water storage area and a water pump, the water pump is connected between the water storage area and the water storage capsule and can draw water in the water storage area and inject it into the water storage capsule; when the water storage capsule is filled with water and bulges, it can protrude upward in the drainage ditch.

[0005] The water storage area is connected to a water leakage port through a flow channel, and the water leakage port is arranged on the ground outside the drainage ditch.

[0006] The water storage area is connected to the drainage ditch through a flow channel.

[0007] A water level sensing device is provided in the water storage area, and the water level sensing device is connected to the controller of the water pump. When the water level sensing device senses that the water level in the water storage area exceeds a preset threshold, the controller controls the water pump to start.

[0008] The rain grate is hinged to the edge of the drainage ditch, and when the water storage capsule is filled with water and bulges, the rain grate can be lifted up.

[0009] The flood protection area includes an underground garage.

[0010] The rain grate comprises a first part and a second part which are arranged opposite to each other on the left and right sides. The first part and the second part respectively comprise a plurality of crossbars. One end of the crossbar is mounted on the rotating shaft, and the other end is overlapped on the edge of the drainage ditch.

[0011] In the first part or the second part, a plurality of crossbars are connected to one of the rotating shafts.

[0012] A torsion spring is arranged on the rotating shaft, and is used for applying a restoring force to the first part or the second part after the first part or the second part is lifted.

[0013] The drainage ditch is also provided with a limiting portion, and when the first part or the second part is erected, the limiting portion can block the first part or the second part to limit its continued rotation.

[0014] By adopting the above technical scheme, when encountering heavy rain, the water on the ground will enter the water storage area. The water in the water storage area can be pumped out by a water pump and injected into the water storage capsule. The water storage capsule expands after being filled with water and extends upward from the drainage ditch, thereby forming a waterproof wall to prevent the external water from entering the flood control area. Compared with the prior art, the flood control structure of the present invention does not require sandbags to be prepared, nor does it require operators to manually build flood control dams. It is very convenient and efficient to pump and inject water by a water pump, and the flood control effect is good. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention is further described in detail below through the accompanying drawings and specific embodiments.

[0023] As shown in the figure, the flood control structure of the present invention includes a drainage ditch 1 arranged outside the flood control area, a rain grate 2 is detachably provided on the drainage ditch 1, a water storage capsule 3 is provided in the drainage ditch 1, the drainage ditch 1 is arranged horizontally, the water storage capsule 3 is a long strip-shaped bag, and extends along the long direction of the drainage ditch 1, and the water storage capsule 3 is emptied when storing in the drainage ditch.

[0024] The flood control structure further includes a water storage area 4 and a water pump 5. In this embodiment, the water storage area 4 is connected to the water leakage port 6 through a flow channel. The water leakage port 6 is arranged on the ground outside the drainage ditch 1. When encountering heavy rain, rainwater accumulated on the ground can enter the water storage area 4 through the flow channel. Of course, in other embodiments, the water storage area 4 can also be connected to the drainage ditch 1 through a flow channel, and the accumulated water enters the drainage ditch 1 and then flows into the water storage area 4. The water storage area 4 can be a water storage tank arranged underground.

[0025] The water pump 5 is connected between the water storage area 4 and the water storage capsule 3 and can extract water from the water storage area 4 and inject it into the water storage capsule; when the water storage capsule 3 is filled with water and swells, it can be extended upward in the drainage ditch 1, such as Figure 3 shown.

[0026] A water level sensing device is provided in the water storage area 4 , and the water level sensing device is connected to the controller of the water pump 5 . When the water level sensing device senses that the water level in the water storage area 4 exceeds a preset threshold, the controller controls the water pump 5 to start.

[0027] The rain grate 2 is hinged to the edge of the drainage ditch 1, and when the water storage capsule 3 is filled with water and bulges, the rain grate 2 can be lifted up.

[0028] like Figure 5 , 6As shown, the rain grate 2 includes a first part 21 and a second part 22 which are arranged opposite to each other on the left and right sides, and the first part 21 and the second part 22 respectively include a plurality of crossbars 20, one end of the crossbar 20 is mounted on the rotating shaft 201, and the other end is overlapped at the edge of the drainage ditch. When the water storage capsule 3 swells, the first part 21 and the second part 22 are respectively opened to both sides, thereby supporting the left and right sides of the water storage capsule 3 to prevent the water storage capsule 3 from falling. The plurality of crossbars 20 located on the first part 21 can be connected to one rotating shaft 201 at the same time, and each crossbar 20 can be connected to one rotating shaft 201. Similarly, the plurality of crossbars 20 located on the second part 22 can be connected to one rotating shaft 201 at the same time.

[0029] In one embodiment, a torsion spring may be installed on the rotating shaft 201 to apply a restoring force to the first part 21 or the second part 22 after it is lifted. In another embodiment, the drain ditch 1 is further provided with a limiting portion 11, which can block the first part 21 or the second part 22 to limit its continued rotation when the first part 21 and the second part 22 are erected. Figure 7 As shown, the limiting portion 11 may be an eave portion arranged at the edge of the drainage ditch 1 .

[0030] In this embodiment, the flood control area is an underground garage. Of course, in other embodiments, the flood control structure can also be arranged in other low-lying areas or outside the flood control area, such as outside the street tunnel, underground tunnel entrance, residential area entrance, etc.

[0031] By adopting the above technical scheme, when encountering heavy rain, the flood control structure of the present invention will cause the accumulated water on the ground to enter the water storage area 4. The water in the water storage area 4 can be pumped out by the water pump 5 and injected into the water storage capsule 3. The water storage capsule 3 expands after being filled with water and extends upward from the drainage ditch 1, thereby forming a waterproof wall to prevent the accumulated water from the outside from entering the flood control area. Compared with the prior art, the flood control structure of the present invention does not require sandbags to be prepared, nor does it require operators to manually build flood control dams. It is very convenient and efficient to pump and inject water by the water pump 5, and the flood control effect is good.

[0032] Obviously, the above embodiments are only examples for clear explanation, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the protection scope of the invention.
