Description

Technical Field

[0001] The invention relates to the field of flood prevention equipment, in particular to an automatic multifunctional flood prevention device. Background Art

[0002] When carrying out flood prevention and rescue tasks, building embankments and dams is an effective means. Flood prevention sandbags or flood prevention bags made of water-absorbing and expanding materials are usually used to form the dam body, and for large floods, multiple flood prevention bags are stacked to increase the height. However, in the prior art, flood prevention bags are usually placed directly on the ground. When facing the strong impact of floods, there is a risk of displacement, which may lead to dam collapse. Secondly, the functions of existing flood prevention bags are relatively simple, and they only play the role of blocking floods. They cannot monitor environmental information, especially hydrological information, because monitoring water flow information around the dam body can obtain first-hand data, and can timely evaluate the impact of floods and make timely adjustments. Thirdly, when not in use, the existing flood prevention bags are simply stacked together, which is very unsightly. In 2023, the central government proposed the requirements of actively promoting the transformation of urban villages and the construction of "dual-use" public infrastructure in super-large and megacities. Therefore, it is necessary to improve the existing flood prevention bags to make them multifunctional and achieve the goal of "dual-use". Summary of the invention

[0023] See also Figure 1The flood prevention device of the present invention includes a flood prevention unit 1, which includes a top plate 3, a bottom plate 4, and a retractable barrel body 5 located between the top plate 3 and the bottom plate 4, and a water inlet hole 6 and a drainage hole 7 are arranged around the lower part of the barrel body 5. The flood prevention unit has a filling body 2, and the filling body 2 expands in volume after absorbing water. The top plate is provided with a first through hole 31, and the bottom plate is provided with a second through hole 41. The barrel body 5 has a vertical channel 8 connecting the first through hole 31 and the second through hole 41. The flood prevention device also includes a reinforcement component 9, and the vertical channel 8 is used to place the reinforcement component 9.

[0024] The filler 2 may be made of a water-absorbing sponge or a water-absorbing resin, etc. The retractable cylinder 5 is in a contracted state in a natural state, for example, it may be a corrugated cylinder made of rubber.

[0025] After absorbing the liquid, the filler 2 expands and increases in volume, and the retractable cylinder 5 stretches under the force of the expansion of the filler. At the same time, the weight of the entire flood control bag increases due to the absorption of a large amount of liquid. When used for flood control, it absorbs a large amount of water on the one hand, and increases its own weight on the other hand, thereby playing a role in blocking floods.

[0026] After the flood prevention work is completed, a certain pressure is applied to the upper plate 3 , the filling body 2 is compressed, and the absorbed water is discharged from the drainage holes 7 .

[0027] Figure 1 , the structure of the first embodiment of the reinforcement component is shown. The reinforcement component 9 is in the shape of a nail. The reinforcement component 9 is partially located in the vertical channel 8, which is equivalent to providing "reinforcement ribs" between the filling bodies 2, so that the structure of the entire flood control unit 1 is stable and not easy to topple under the impact of the water flow. At the same time, a conical head is provided at the bottom of the reinforcement component 9, which can be inserted into the ground to strengthen the stability of the flood control unit 1. When in use, the reinforcement component 9 can be placed in the flood control unit 1 and nailed to the ground before the flood arrives as needed, and space is left for the barrel body 5 to extend in the height direction. Alternatively, after the barrel body 5 expands into place, the reinforcement component is installed.

[0028] Those skilled in the art will appreciate that a plurality of vertical channels 8 may be provided in the barrel body 5 .

[0029] The above-mentioned reinforcement assembly 9 requires manual assistance when in use. The present invention also provides a second embodiment of the reinforcement assembly, which realizes automatic operation through the cooperation of a driving device and a drill bit.

[0030] See also Figure 2The reinforcement assembly 9 includes a housing 91, a drill bit 92, a driving device 93, a drill rod 94, a battery 95, and a control unit 96. The driving device 93 and the battery 95 are located in the housing 91. The drill bit 92 is fixedly connected to the drill rod 94. The driving device is used to drive the drill rod 94 to move up and down and rotate. The control unit 96 is used to control the driving device 93 to work, and the drill bit 92 can extend out of the second through hole 41. The driving device 93 includes a power transmission device such as a motor and a gear to realize the movement and rotation of the drill bit 92, which is a well-known technology in the art and will not be described in detail.

[0031] When in use, the control unit 96 receives a control signal, the driving device 93 is started, and the drill rod 94 is driven to move. The drill bit 92 can drill into the ground under the drive of the drill rod 94, thereby firmly fixing the flood control device to the ground.

[0032] Further, see Figure 2 The reinforcement component 9 further includes a head 97, which is located above the reinforcement component 9 and is used to limit the free movement of the reinforcement component 9 in the vertical channel 8. For example, the head 97 includes a disc, which is detachably connected or fixedly connected to the upper end of the shell 91, and the projection area of ​​the disc on the horizontal plane is larger than the area of ​​the first through hole 31, so that after the reinforcement component is inserted into the vertical channel 8, when the disc 971 moves downward, it will eventually be blocked by the top plate 3 and will not slide out from the lower end of the vertical channel 8.

[0033] See also Figure 3 , is a structural diagram of the third embodiment of the reinforcement component, which is different from the second embodiment in the structure of its head 97. The head 97 includes a screw 972 and a pressure plate 973. The screw 972 includes a screw head 9721 and a rod 9722. The rod 9722 can be screwed into the top of the housing 91. The pressure plate 973 has a central through hole for sleeve-mounting the pressure plate 973 on the rod 9722. The projection area of ​​the screw head 9721 on the horizontal plane is larger than the area of ​​the central through hole. The projection area of ​​the outer contour of the pressure plate 973 on the horizontal plane is larger than the area of ​​the first through hole 31.

[0034] Therefore, the pressure plate 973 is restricted from moving between the screw head 9721 and the shell 91, and since the projection area of ​​the outer contour of the pressure plate 973 on the horizontal plane is larger than the area of ​​the first through hole 31, after the reinforcement assembly is inserted into the vertical channel 8, the pressure plate 873 can ensure that the reinforcement assembly will not slip out from the lower end of the vertical channel 8.

[0035] Furthermore, the flood control unit 1 also includes a retractable hollow cylinder, the vertical channel 8 is formed inside the hollow cylinder, and the retractable hollow cylinder is a corrugated cylinder made of elastic material, one end of the corrugated cylinder is connected to the top plate 3, and the other end is connected to the bottom plate 4. By using a retractable hollow cylinder to form the vertical channel 8, on the one hand, the support for the barrel body is strengthened, and on the other hand, it is helpful to guide the reinforcement component to be inserted into the barrel body. It can be understood by those skilled in the art that the retractable hollow cylinder includes a plurality of sleeves, and the plurality of sleeves include at least two sleeves respectively connected to the top plate 3 and the bottom plate 4. Figure 4 As shown, the retractable hollow cylinder is composed of two sleeves, the first sleeve 81 is located at the top and fixedly connected to the top plate 31, and the second sleeve 82 is located at the bottom and fixedly connected to the bottom plate 4. When the barrel body 5 expands and the height increases, sliding occurs between the first sleeve 81 and the second sleeve 82 to adapt to the increase in height.

[0036] As a further improvement, since the reinforcement component 9 itself includes a shell 91, the shell 91 can be configured as a plurality of mutually nested cylinders, and the plurality of mutually nested cylinders can slide relative to each other to form a retractable shell 91. Figure 5 The housing 91 includes two cylinders, the lower cylinder can slide in the upper cylinder, and the driving device is preferably arranged in the lower cylinder to lower the center of gravity so that the drill bit remains stable when working.

[0037] See also Figure 6 The flood control device may also include a plurality of flood control units 1 stacked up and down, and the vertical channels 8 of the plurality of flood control units 1 are aligned up and down, so as to form water retaining dams of different heights according to actual application scenarios. Correspondingly, the reinforcement assembly 9 has a variety of length specifications, passing through the vertical channels 8 of the plurality of flood control units 1, so as to adapt to the stacked flood control units.

[0038] Furthermore, concentrated disinfectant capsules or concentrated fertilizer capsules are pre-buried inside the barrel 5. Since floods are usually accompanied by secondary disasters such as disease transmission, by burying disinfectant capsules in the barrel 5, when the barrel 5 is infiltrated by floods, the capsules melt and rupture, and the disinfectant inside dissolves in the water, thereby disinfecting the disaster-stricken area and reducing the risk of secondary disasters. By burying concentrated fertilizer capsules, post-disaster fertilization can also be carried out in the disaster-stricken areas, especially in farmland and other areas, so as to make rational use of water resources.

[0039] Furthermore, an environmental monitoring sensor is provided on the outside of the barrel 5, and the environmental monitoring sensor is used to detect one or more of the flow rate, flow direction, temperature, depth, and pH value of water, and the environmental monitoring sensor is connected to the control unit 96. Real-time data is obtained through the environmental monitoring sensor for detection and feedback, providing timely and accurate data information for secondary disaster (such as leakage of hazardous chemicals, breach) warning. The connection can be wired or wireless, preferably wireless.

[0040] The flood control device of the present invention provides a "dual-use" function, and can be combined into public facilities (such as flower beds, seats, etc.) according to the needs of actual application scenarios to beautify the environment and meet public needs, and provide "normal services". When "used in an emergency", it can be quickly deployed to carry out disaster prevention and mitigation work. At the same time, the liquid absorbed by the filling body is not limited to water, and it can also provide a "solidification" transportation function for petroleum products and hazardous chemicals (liquids), and absorb petroleum products and hazardous chemicals (liquids) into the bag body to form a "solidified" independent package, which is discharged after being transported to the destination. The liquid discharged from the flood control bag can continue to be used.

[0041] Furthermore, in order to allow the flood control unit to provide more abundant "dual-use" functions, see Figure 7-8 The flood control unit 1 also includes a water retaining plate 10. A slide rail 51 is provided outside the barrel body 5. A groove 52 extending up and down is provided in the middle of the slide rail 51. A shaft 101 protrudes outward from the upper end of the water retaining plate 10. The shaft 101 is located in the groove 52, so that the water retaining plate 10 can slide up and down and rotate relative to the slide rail 41. When the filling body 2 does not absorb water and expand, the vertical height H of the water retaining plate 10 is greater than the height h of the bottom end of the groove 52 from the ground. When the filling body 2 absorbs water and expands, the slide rail 51 moves up with the expansion of the barrel body 5, and the shaft 101 slides downward along the groove 52. The water retaining plate can also be tilted to form a water retaining surface (see Figure 8 ), which can reduce the impact of floods.

[0042] It is understood by those skilled in the art that the water retaining plate 10 may also be an arc-shaped structure (see Fig. 9 ).

[0043] When not in a flood control state, the water retaining plate 10 can be used as a publicity signboard to provide disaster prevention and mitigation science popularization, disaster safety site guidance, and public welfare advertisement display. Preferably, the water retaining plate 10 is an electronic panel with a display component and / or a voice component for publicity or emergency broadcasting.
