Description

Technical Field

[0001] The present invention relates to the technical field of interception and water blocking, and in particular to a flood control interception device. Background Art

[0002] Levee breach interception is one of the key links in flood control and emergency rescue. In recent years, with the frequent occurrence of extreme climate events, regional floods and sudden breach risks have put forward higher requirements for the timeliness, adaptability and reliability of interception technologies. Current mainstream interception schemes mostly adopt a coordinated blocking system of "closure piles - closure nets - throwing materials". In this system, the stability of the closure pile is the core factor determining the success or failure of the entire interception. For this reason, in the prior art, support devices are often installed on one or both sides of the closure pile to enhance the anti-overturning capacity of the pile body.

[0003] However, the existing support devices still face the prominent problem that it is difficult to balance deployment efficiency and operational reliability in practical applications. On the one hand, the support device needs to take into account compact storage, convenient transportation and rapid on-site deployment capability, while most existing devices are of fixed type and have large monomer volume. In the scenario where multiple sets of devices are deployed at the same time, the transportation efficiency and on-site erection speed are significantly restricted. On the other hand, due to the simplicity of existing support devices and their application in water flow environments, they still have deficiencies in ensuring their own stability, providing reliable anti-overturning support for closure piles, and even providing reliable safety protection for the entire construction site. Therefore, the existing interception devices still need to be improved in terms of ensuring the due performance of safety, warning and stable support in water flow environments. Summary of the Invention

[0004] The object of the present invention is to provide a flood control interception device, which solves the problems mentioned in the above background art.

[0005] To achieve the above object, the present invention provides the following technical solution: a flood control interception device, comprising a closure net, further comprising a closure pile matched with the closure net, and a support device;

[0006] The support device comprises a bottom frame, a connecting frame is rotatably mounted on the surface of the bottom frame through a stopper, a top frame is fixedly connected to the top of the connecting frame, a water bag is mounted on the inner wall of the bottom frame through a connecting spring, an impeller is arranged on the top frame, a protective net is arranged outside the impeller, overlapping rods are slidably connected to both side inner walls of the top frame, and the two overlapping rods are arranged in a staggered manner;

[0007] Two sets of power generating elements are arranged in the top frame, warning lamps corresponding to the power generating elements are mounted on the top surface of the top frame. When the impeller rotates, the warning component drives the power generating elements to generate current for the warning lamps to work, and on the premise of not affecting the operation of the warning lamps, the overlapping rods on both sides are driven to extend out from the top frame through the transmission of two sets of cooperative force bearing components;

[0008] It also includes a self-weight lifting component. During the continuous rotation of the impeller, the water bag is filled with water and expanded through the transmission of the self-weight lifting component to improve the stability of the support device.

[0009] Optionally, the warning component includes a positioning plate, the impeller is fixedly connected to the surface of the positioning plate, an internal toothed ring is fixedly connected to the bottom surface of the protective net, the inner and outer sides of the internal toothed ring are rotatably connected to the side wall of the positioning plate and the inner wall of the top frame, respectively, a rotating shaft is fixedly connected to the bottom surface of the positioning plate, the rotating shaft is rotatably connected to the inner wall of the top frame, a first inclined bevel gear is fixedly connected to the surface of the rotating shaft, two support rods are fixedly connected to the inner wall of the top frame, a connecting shaft is rotatably connected to the inner wall of each of the two support rods, and a second inclined bevel gear is fixedly connected to the opposite side of each of the two connecting shafts, the teeth of the second inclined bevel gear meshing with the teeth of the first inclined bevel gear, a power generation chamber and a functional chamber are provided inside the top frame, the connecting shaft passes through the power generation chamber and the functional chamber and is rotatably connected to the inner wall of the top frame, and the power generation element is located in the section of the connecting shaft inside the power generation chamber.

[0010] Optionally, the cooperative force-bearing component includes a slider, which is slidably connected to the inner wall of the functional cavity. A section of the connecting shaft located inside the functional cavity is threaded and connected to a threaded cylinder via the thread. The threaded cylinder is rotatably connected to the inner wall of the slider, and a constraint conversion component for constraining the threaded cylinder is provided inside the slider.

[0011] Optionally, the constraint conversion component includes two extrusion blocks, both of which are slidably connected to the inner wall of the slider. The inner walls of both extrusion blocks are connected to the inner wall of the slider via constraint springs. A pin is fixedly connected to the opposite sides of the two extrusion blocks. A release plate is slidably connected to the inner wall of the slider. A through groove is formed on the surface of the release plate. The pin is slidably connected to the inner wall of the groove. An insertion port adapted to the release plate is formed on the side wall of the threaded cylinder. A protective cylinder is rotatably connected to the end of the threaded cylinder. The protective cylinder is slidably connected to the inner wall of the top frame. The end of the protective cylinder is fixedly connected to the end of the overlapping rod.

[0012] Optionally, the self-weight lifting component includes a piston cylinder assembly installed on the bottom surface of the top frame. The end of the rotating shaft is connected to the drive end of the piston cylinder assembly. A water inlet is provided on the side of the piston cylinder assembly, and water outlets are provided on both the left and right sides of the piston cylinder assembly. A flexible hose is connected to the water outlet. A switchable one-way valve assembly is provided on the water inlet and the two water outlets. Both hoses are connected to the water bag. Both hoses are installed on the surface of the top frame and the connecting frame by snap-fit. A pressure sensor is provided on both water outlets of the piston cylinder assembly.

[0013] Initially, the inlet is in a one-way state. When the pressure sensor detects that the water bag is full, the one-way valve of the inlet on the piston cylinder assembly switches, and the inlet becomes non-one-way. The one-way valves on the two outlets remain in a one-way state. In this state, when the shaft drives the piston cylinder assembly to operate, it will only perform the pumping and draining process and will no longer fill the water bag.

[0014] Optionally, it also includes two sets of self-cleaning components. The self-cleaning components include a steering shaft and a locking block fixedly connected to the top surface of the inclined bevel gear. A grooved wheel is rotatably connected to the top surface of the support rod, and a gear is fixedly connected to the top surface of the grooved wheel. The teeth of the gear mesh with the teeth of the internal gear ring.

[0015] Optionally, the intercepting net is made of high manganese steel, and the intercepting pile is made of high-elasticity seamless steel pipe.

[0016] Optionally, the surface of the intercepting net is treated with both galvanizing and powder coating for double corrosion protection. The longitudinal and transverse meshes of the intercepting net are designed in a wavy pattern, the water-facing surface of the intercepting net is designed with a micro-arc shape, and the intercepting piles are designed with a pointed taper.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] I. This invention utilizes a three-in-one collaborative load-bearing system of interception net, interception pile, and dumped materials to adapt to complex emergency rescue scenarios, achieving the effect of rapid emergency rescue by relying on local materials and without waiting for assistance.

[0019] Second, this invention employs a limiting rotation structure for the base frame and connecting frame. In the non-working state, the connecting frame can be folded back onto the base frame, forming a compact folded shape, significantly reducing storage and transportation volume and facilitating the batch transfer and rapid deployment of multiple units. Once the device is in place, the impeller continuously rotates under the impact of water flow, driving the power generation element through a bevel gear transmission to provide uninterrupted power to the top warning light, eliminating the need for an external power source or battery, truly achieving instant activation upon deployment. The constant flashing of the warning light forms a conspicuous safety marker at the interception operation site, effectively improving construction safety at night and in low-visibility environments, and also addressing the problem of poor power supply reliability in traditional interception operations.

[0020] Third, this invention relies on the continuous power of the rotating impeller to drive the piston cylinder assembly to perform active water pumping. Water is drawn in through the inlet and then filled into a water bag on the base frame via a hose. As the water bag gradually fills and expands, the self-weight of the support device and the ground adhesion increase simultaneously, effectively suppressing the tendency of a single intercepting pile to float and overturn under the impact of water flow. Unlike solutions that add counterweights, this design is more convenient for storage and deployment. Furthermore, the impeller is located at the top of the device, and water storage only begins after the device is basically in place, avoiding instability during deployment and making the deployment more reliable.

[0021] IV. During the continuous rotation of the impeller, the invention drives the slider and constraint assembly to slide along the functional cavity, thereby pushing the overlapping rod to extend from both sides of the top frame. The constraint conversion component uses the linkage of the extrusion block, pin, and inclined groove. After the overlapping rod is fully extended, it automatically disengages, releasing the threaded cylinder from the slider. At this time, the connecting shaft rotates freely without affecting subsequent power generation. Furthermore, the extended overlapping rod forms an interlocking engagement with the corresponding rods of the adjacent support device, causing the rows of support devices to be interconnected and mutually supportive, forming an integral anti-overturning frame. In this way, without interfering with the continuous power supply of the warning lights, individual support devices are connected into a cooperative force-bearing system, significantly improving the overall stability of the diversion pile group under the impact of water flow.

[0022] V. Considering that water flow often carries a large amount of floating debris during interception operations, although the protective net can effectively intercept debris to ensure the normal operation of the impeller, the accumulation of debris will block the water flow after long-term operation. Therefore, this device integrates a steering shaft and locking block at the top of the inclined bevel gear, forming an intermittent transmission mechanism with the grooved wheel and gear. Through the meshing of the gear and the internal gear ring, the protective net is driven to deflect at a small angle and low speed, causing the floating debris attached to it to be deflected to the non-blocking area and then washed away by the water flow, achieving a self-cleaning effect. Furthermore, due to the small deflection angle and slow speed, the self-cleaning process will not interfere with the normal rotation of the impeller, realizing long-term maintenance-free operation of the protective net.

Detailed Description of Embodiments

[0033] Hereinafter, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without making creative work shall fall within the protection scope of the present invention.

[0034] First Embodiment:

[0035] Please refer to Figures 1 to 9 , the present invention provides a flood control interception device, comprising an interception net 1 and interception piles 2 matched with the interception net 1. The interception net 1 is made of high manganese steel, the interception piles 2 are made of high-elasticity seamless steel pipes, the surface of the interception net 1 is subjected to double anti-corrosion treatment of galvanizing and plastic spraying, the warp and weft meshes of the interception net 1 adopt a wavy design, the water-facing surface of the interception net 1 adopts a micro-arc design to balance flow passing performance and water retaining effect, and the interception piles 2 adopt a tapered tip design. When interception is required, a long-arm pile driver is used to drive the interception piles 2 in according to the principle of "from near to far", the driving depth of the interception piles 2 is not less than two-thirds of their own length to ensure stable rooting, the top of the piles is higher than the water surface, and the spacing between adjacent piles is adjusted according to the model of the interception net 1. Subsequently, a long-arm machine is used to stably attach the interception net 1 of the selected model to the inner side of the interception piles 2, ensuring uniform stress on the mesh sheet in longitudinal and transverse directions, and the edge is closely attached to the interception piles 2 without loose gaps. The shape of the interception net 1 is adjusted according to the flow direction to enhance impact resistance.

[0036] After the interception net 1 is installed in place, gabions or sandbags are thrown and stacked layer by layer from the bottom in a trapezoidal arrangement. The gabions are closely attached to the interception net 1 to share hydrostatic pressure and water flow impact. During the throwing process, the flow pattern shall be observed to avoid local overload of the mesh caused by centralized throwing at a single point. If serious flow around is found, supplementary throwing materials shall be added in time to ensure that the backwater in front of the interception net 1 is stable, and there is no obvious vortex or material loss. After effective blocking, sandbags shall be continuously stacked to complete embankment restoration, forming a complete protection.

[0037] If the water flow impact is strong, additional support devices should be added to ensure the overturning resistance of the intercepting pile 2. The support device includes a base frame 3, on the surface of which a connecting frame 4 is rotatably mounted via a limiter. A top frame 5 is fixedly connected to the top of the connecting frame 4. When using the support device, transport it from the warehouse to the site, first open the limiter, and then unfold the connecting frame 4 to... Figure 3 As shown, a long-arm machine is then used to attach the support device to the surface of the diversion pile 2. The triangular support formed by the base frame 3, connecting frame 4, and top frame 5 increases the overturning resistance of the diversion pile 2. Conversely, [the following text appears to be unrelated and possibly a separate sentence fragment: ...by...] Figure 3 It can be seen that when not in use, the connecting frame 4 can be stored on the base frame 3, forming a fold, which facilitates storage and transportation.

[0038] Furthermore, a water bag 7 is installed on the inner wall of the base frame 3 via a connecting spring 6, an impeller 8 is installed on the top frame 5, a protective net 9 is installed on the outer side of the impeller 8, and overlapping rods 10 are slidably connected to the inner walls on both sides of the top frame 5. The two overlapping rods 10 are arranged in an alternating manner. Two sets of power generation elements 11 are installed inside the top frame 5, and a warning light 12 corresponding to the power generation element 11 is installed on the top surface of the top frame 5. When the impeller 8 rotates, the warning component drives the power generation element 11 to generate current, which powers the warning light 12.

[0039] Specifically, the warning components include a positioning plate 13, an impeller 8 fixedly connected to the surface of the positioning plate 13, an internal gear ring 14 fixedly connected to the bottom surface of the protective net 9, the inner and outer sides of the internal gear ring 14 being rotatably connected to the side wall of the positioning plate 13 and the inner wall of the top frame 5 respectively, a rotating shaft 15 fixedly connected to the bottom surface of the positioning plate 13, the rotating shaft 15 being rotatably connected to the inner wall of the top frame 5, a bevel gear 16 fixedly connected to the surface of the rotating shaft 15, two support rods 17 fixedly connected to the inner wall of the top frame 5, a connecting shaft 18 rotatably connected to the inner wall of each of the two support rods 17, and bevel gears 19 fixedly connected to the opposite sides of each of the two connecting shafts 18, the teeth of the two bevel gears 19 meshing with the teeth of the bevel gear 16.

[0040] Once the support device is in place, the impeller 8 rotates due to the impact of the water flow. This causes the positioning plate 13 to rotate, which in turn drives the rotating shaft 15 to rotate. During the rotation of the rotating shaft 15, the connecting shafts 18 on both sides rotate synchronously through the transmission of the first inclined bevel gear 16 and the two second inclined bevel gears 19. The top frame 5 has a power generation chamber 20 and a functional chamber 21. The connecting shaft 18 passes through the power generation chamber 20 and the functional chamber 21 and is rotatably connected to the inner wall of the top frame 5. The power generation element 11 is located on a section of the connecting shaft 18 inside the power generation chamber 20.

[0041] Taking a single-sided structure as an example, during the rotation of the connecting shaft 18, the power generation element 11 is driven to rotate, thereby providing a continuous current to the warning light 12, so that the warning light 12 keeps flashing. In the environment of blocking a breach, power resources are especially precious. Through the above method, on the one hand, the setting of the warning light 12 provides a safety warning for the blocking work, and on the other hand, the high-velocity water flow impact is used to convert electricity, which solves the low reliability of measures such as batteries and line construction under blocking conditions. It can be lit immediately and is easy to use.

[0042] It should be emphasized that in this embodiment, impeller 8 refers to the water turbine assembly, which has a half-covered outer shell on its surface. Under the impact of water flow, impeller 8 can rotate normally.

[0043] Example 2, based on the above examples:

[0044] Please see Figures 2 to 7 To improve the stability of a single support device, the water bag 7 is inflated by the transmission of the self-weight lifting component during the continuous rotation of the impeller 8. Specifically, the self-weight lifting component includes a piston cylinder assembly 30 installed on the bottom surface of the top frame 5. The end of the rotating shaft 15 is connected to the drive end of the piston cylinder assembly 30. The side of the piston cylinder assembly 30 has a water inlet, and the left and right sides of the piston cylinder assembly 30 have water outlets. A hose 31 is connected to the water outlet. A switchable one-way valve assembly is provided on the water inlet and the two water outlets. Both hoses 31 are connected to the water bag 7. Both hoses 31 are installed on the surface of the top frame 5 and the connecting frame 4 by buckles 32. Pressure sensors are provided on both water outlets of the piston cylinder assembly 30.

[0045] In the initial state, the water inlet is in a one-way state. During the rotation of the rotating shaft 15, it will also drive the piston cylinder assembly 30 to operate. Water is drawn in from the water inlet, passes through two hoses 31, and fills the water bag 7. At this time, the water bag 7 gradually fills up. The filling water bag 7 can make the support device more stable.

[0046] When the pressure sensor detects that the water bag 7 is full, the one-way valve of the water inlet on the piston cylinder assembly 30 switches, and the water inlet becomes non-one-way. The one-way valves on the two water outlets remain in one-way. In this state, when the rotating shaft 15 drives the piston cylinder assembly 30 to operate, it will only perform the water pumping and draining process and will no longer fill the water bag 7 with water.

[0047] It should be noted that, firstly, the piston cylinder assembly 30 is a commonly used kit in the prior art. In this embodiment, it is only used as a conversion tool for pumping. The specific principle will not be elaborated here. Those skilled in the art can purchase suitable components for assembly according to the required size.

[0048] Secondly, this embodiment uses the rotation of the impeller 8 to fill the water bag 7 with water, thereby achieving the functions of anti-buoyancy and anti-overturning. Compared with some existing technologies that directly add counterweights, this method is more conducive to the storage and deployment of the support device. Moreover, compared with the method of directly pouring water in, the active water pumping method, since the impeller 8 is located above the entire support device, means that the support device is basically in place when it rotates due to the water flow. This avoids the situation where the entire support device becomes unstable due to the influence of the water flow as soon as it is immersed in water.

[0049] Example 3, based on the above examples:

[0050] Please see Figure 2 , Figure 3 , Figures 5 to 9 To improve the overall stability of multiple support devices, without affecting the operation of the warning light 12, the connecting rods 10 on both sides are driven to extend from the top frame 5 through the transmission of two sets of cooperative force-bearing components. Specifically, the cooperative force-bearing components include a slider 22, which is slidably connected to the inner wall of the functional cavity 21. A section of the connecting shaft 18 located in the functional cavity 21 is threaded and connected to a threaded cylinder 23 through the thread. The threaded cylinder 23 is rotatably connected to the inner wall of the slider 22. During the rotation of the connecting shaft 18, the threaded section in the functional cavity 21 will rotate synchronously.

[0051] The slider 22 is equipped with a constraint conversion component for constraining the threaded cylinder 23. The constraint conversion component includes two extrusion blocks 24, both of which are slidably connected to the inner wall of the slider 22. The inner walls of the two extrusion blocks 24 are connected to the inner wall of the slider 22 through constraint springs 25. The opposite sides of the two extrusion blocks 24 are fixedly connected to a pin 26. The inner wall of the slider 22 is slidably connected to a release plate 27. The surface of the release plate 27 is provided with a through groove 28. The pin 26 is slidably connected to the inner wall of the groove 28. The side wall of the threaded cylinder 23 is provided with an insertion port that matches the release plate 27. The end of the threaded cylinder 23 is rotatably connected to a protective cylinder 29. The protective cylinder 29 is slidably connected to the inner wall of the top frame 5. The end of the protective cylinder 29 is fixedly connected to the end of the overlapping rod 10.

[0052] Specifically, in the initial state, the release plate 27 is inserted into the socket on the threaded cylinder 23, meaning that the slider 22 and the threaded cylinder 23 are under the same constraint. Constrained by the functional cavity 21, the slider 22, threaded cylinder 23, and internal constraint conversion components move together during the rotation of the connecting shaft 18. During this process, the connecting rod 10 extends from the side of the top frame 5 via the transmission of the protective cylinder 29. As the connecting shaft 18 continues to rotate, when the pressing block 24 contacts the inner wall of the functional cavity 21, the pressing block 24 presses the constraint spring 25, causing relative movement between the pin 26 and the inclined groove 28. This drives the release plate 27 to move vertically upwards through the inclined groove 28, thus disengaging the release plate 27 from the socket. After disengagement, the slider 22 and threaded cylinder 23 lose the same constraint. Subsequent rotation of the connecting shaft 18 will only cause the threaded cylinder 23 to rotate via its threads, while the slider 22 remains in the same position.

[0053] The above method enables the impeller 8 to rotate, driving the connecting rod 10 to extend from the side, without affecting the impeller 8's continued transmission process after extension. And after the connecting rod 10 extends, as... Figure 9 As shown, by misaligning the overlapping rods 10 extending from the adjacent support devices, multiple support devices in a row can be staggered, thereby improving the overall stability of the multiple support devices, and thus improving the overall stability of the multiple diversion piles 2.

[0054] Example 4, based on the above examples:

[0055] Please see Figures 1 to 3 , Figures 5 to 7 The support device also includes two sets of self-cleaning components. The self-cleaning components include a steering shaft 33 fixedly connected to the top surface of the inclined bevel gear 16 and a locking block. The top surface of the support rod 17 is rotatably connected to a grooved wheel 34, and the top surface of the grooved wheel 34 is fixedly connected to a gear 35. The teeth of the gear 35 mesh with the teeth of the internal gear ring 14.

[0056] Specifically, considering that there are often many floating objects in the water flow during interception operations, the protective net 9 can intercept these floating objects, preventing them from affecting the rotation of the impeller 8. During the continuous rotation of the inclined bevel gear 16, it synchronously drives the top steering shaft 33 and the locking block to perform circular motion. The steering shaft 33, the locking block, and the grooved wheel 34 form a grooved wheel structure. That is, when the inclined bevel gear 16 rotates continuously, it drives the grooved wheel 34 to rotate intermittently. Through the intermittent rotation of the grooved wheel 34 and the transmission of the gear 35, the internal gear ring 14 is driven to rotate intermittently. This, in turn, causes the protective net 9 to rotate intermittently, thus deflecting the floating objects onto it to a position where they are not blocked by the protective net 9. The floating objects can then be removed by the water flow, achieving a self-cleaning effect.

[0057] It is worth noting that, firstly, the locking block is a common configuration in existing Geneva structures, which ensures that the Geneva 34 does not rotate when the steering shaft 33 is not engaged with the Geneva 34. Therefore, it is not shown in the figure, and the specific settings will not be described in detail. Secondly, during the rotation of the internal gear ring 14 driven by the gear 35, due to the special nature of the transmission ratio, the deflection of the protective net 9 has the characteristics of a small single angle and a slow single speed, so it will not affect the rotation process of the impeller 8 driven by the water flow.

[0058] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
