Description

Technical Field

[0001] The invention relates to the field of flood control equipment, and in particular to a breach dam plugging device. Background Art

[0002] Flood prevention is a key task to ensure the safety of people's survival and production. When a flood occurs, it is usually necessary to prepare multiple plans to avoid dangerous situations through various flood prevention measures and flood control project scheduling.

[0003] Even so, dam breaches caused by various factors are still relatively common in some local areas. Usually, once a dam breaches, the water is extremely high, and conventional earth-rock blocking methods are ineffective, and vertical blocking methods are not feasible due to the impact of water flow. In response to the above situation, the most common blocking method in recent years is to load trucks with stones and rush into the breach location for blocking. However, this blocking method is costly, especially due to objective conditions such as bumpy roads, which causes the truck to rush into the river embankment at a position that is inconsistent with the preset position, resulting in poor blocking effects that cannot be controlled. There is currently a lack of corresponding solutions to the above situations. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a breach dam blocking device which has a simple structure, is safe to implement, meets the conditions for rapid response to various types of dam breach dangers, combines single or multiple devices, and is placed at the breach position to block the water flow, thereby facilitating further flood prevention construction.

[0005] The device comprises a water retaining box, wherein the water retaining box comprises a front retaining surface and a rear retaining surface, and a buffer shell is arranged between the front retaining surface and the rear retaining surface; The front baffle surface is provided with a blocking net; the blocking net allows water to pass through and initially blocks the water flow to prevent large stones from entering the buffer shell and interfering with subsequent actions; The rear baffle surface is provided with a water-passing window, and a water-blocking baffle is provided in the buffer shell corresponding to the position of the water-passing window; The water retaining baffle is dynamically connected to the flip unit, and the action of the flip unit drives the water retaining baffle to flip and block the water-through window; An anti-falling support rod is provided between the front blocking surface and the rear blocking surface, and a hoisting member is provided on the water retaining box and the anti-falling support rod.

[0006] The effect achieved in this way is that the equipment is lifted by cranes and other engineering vehicles on the side of the breach position and dropped into the breach position. During the dropping process, the front baffle and the rear baffle are connected to facilitate the smooth lowering of the equipment. After the lowering is completed, the flip unit is actuated, and the water-blocking baffle rotates to block the water-passing window to form a water flow blockage. The anti-collapse support rods are used to fix the equipment in the water body, thereby achieving the blocking of the breach position.

[0007] The beneficial effects of the present invention are as follows: the present invention solves many inconveniences in the construction of dam breach plugging in the prior art, and provides a new idea for plugging dam breaches. Compared with the prior art plugging methods, the present invention has the characteristics of simple structure, low plugging investment cost, strong applicability, safer construction and better plugging effect. It can recover more economic losses in emergency construction, reduce the risk of breach, and has greater safety promotion value. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0009] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The breach dam plugging device of the present invention comprises a water retaining box 1, wherein the water retaining box 1 comprises a front retaining surface 11 and a rear retaining surface 12, and a buffer shell 13 is arranged between the front retaining surface 11 and the rear retaining surface 12; The front blocking surface 11 is provided with a blocking net 112; the blocking net 112 allows water to pass through and initially blocks the water flow to prevent large pieces of stone from entering the buffer housing 13 and interfering with subsequent actions; The rear baffle surface 12 is provided with a water-passing window, and a water-blocking baffle 34 is provided in the buffer shell 13 corresponding to the position of the water-passing window. The water-blocking baffle 34 is connected to the flip unit by power, and the action of the flip unit drives the water-blocking baffle 34 to flip and block the water-through window; An anti-falling support rod 2 is also provided between the front blocking surface 11 and the rear blocking surface 12 , and a hoisting member 6 is also provided on the water retaining box 1 and the anti-falling support rod 2 .

[0010] The effect achieved in this way is that the equipment is lifted up by a crane or other engineering vehicle on the side of the breach position and dropped into the breach position. During the dropping process, the front blocking surface 11 and the rear blocking surface 12 are connected to facilitate the smooth lowering of the equipment. After the lowering is completed, the flip unit is actuated, and the water-blocking baffle 34 rotates to block the water-passing window to form a water flow blockage. The anti-collapse support rod 2 is used to fix the equipment in the water body, thereby achieving the blocking of the breach position.

[0011] Furthermore, the front blocking surface 11 and the rear blocking surface 12 are arranged axially symmetrically; The water-passing windows are an even number, and the multiple water-passing windows are arranged on the rear baffle surface 12 in the form of an axisymmetric array, and the reinforcing purlins 4 are between the water-passing windows; Corresponding to the water-passing window, a blocking net 112 is provided on the front baffle surface 11 to assemble the window, and the blocking net 112 is fixedly arranged on the blocking net 112 to assemble the window; Reinforcing ribs are fixedly disposed on the outer sides of the front blocking surface 11 and the rear blocking surface 12 .

[0012] Preferably, the reinforcing ribs are channel steels.

[0013] The effect achieved by this is to enhance the strength of the equipment itself and cope with impact water flows of different intensities.

[0014] Furthermore, the buffer shell 13 is in the form of a rectangular shell, including upper and lower baffles and two side baffles that are arranged oppositely, and the length and width of the buffer shell 13 are smaller than the length and width of the front baffle surface 11 and the rear baffle surface 12.

[0015] The effect achieved by this is to optimize the assembly structure and facilitate stacking of multiple devices up and down.

[0016] Furthermore, a plurality of assembly stop rods 131 are disposed outside the buffer shell 13 , and the edge of the front of the front stop surface 11 is in the form of an outwardly protruding rack 111 , and the width of the assembly stop rods 131 is not greater than the tooth spacing of the rack 111 .

[0017] Preferably, there are twelve assembly baffles 131 in total, and the twelve assembly baffles 131 are evenly arrayed and respectively disposed outside the upper and lower baffles and two side baffles of the buffer shell 13 .

[0018] Preferably, the assembly baffle rod 131 on at least one side of the buffer shell 13 is a sharp baffle rod, the purpose of which is to have the tip of the sharp baffle rod facing downward and piercing into the bottom of the water flow; and when multiple boxes are stacked, only the assembly baffle rod 131 on the bottom surface of the lowest box is a baffle rod with a sharp end.

[0019] The effect achieved by this is that when multiple water retaining boxes 1 are stacked up and down for construction, the assembly stopper rod 131 of the upper box body is partially embedded in the tooth gap of the rack 111 of the front stop surface 11 of the lower box body, which plays a role in stabilizing the assembly.

[0020] Furthermore, a bolt base is provided on the buffer shell 13, and the assembly stop rod 131 is screwed on the bolt base.

[0021] The effect achieved by this is the quick disassembly and assembly of the assembling block rod 131 .

[0022] Furthermore, a waterproof sandwich layer 3 is provided in the buffer shell 13, and a turnover unit is provided in the waterproof sandwich layer; The flip unit includes a battery, a control unit 31 and an action unit; The battery is electrically connected to the control unit 31 and the action unit, the control unit 31 at least includes a timing module and a signal reporting module, and the control unit 31 is signal-connected to the action unit; The action unit includes a power mechanism A32 and a power mechanism B33. The power mechanism A32 and the power mechanism B33 are respectively connected to an actuating rod through a coupling, and the water retaining baffle 34 is fixedly arranged on the actuating rod.

[0023] Preferably, the battery is a rechargeable battery; the control unit 31 is a PLC or a microcomputer.

[0024] The effect achieved in this way is that the execution time of the action unit is preset. When the blocking device as a whole enters the water body and the execution time is reached, the control unit 31 reports a signal to the action unit, the action unit is actuated, the water-blocking baffle 34 rotates, and the water-passing window is blocked.

[0025] That is to say, before and when the device enters the water body, the water-blocking baffle 34 is in a retracted state to prevent water flow from impacting the device, which would prevent the device from being placed in the water body.

[0026] Furthermore, the power mechanism A and the power mechanism B adopt motors or mechanical actuators.

[0027] The actuator mentioned here is a mature device such as a fire damper actuator in the prior art, and the specific structure is not repeated here. The implementation purpose is to achieve a rapid response of the device, that is, a rapid response of the water retaining baffle.

[0028] Furthermore, the power mechanism A32 and the power mechanism B33 are respectively arranged at the upper and lower parts of the waterproof sandwich layer, and the actuator rod passes through the sandwich layer, and its end is rotatably arranged on the inner surface of the buffer housing 13 through a bearing; On the inner surfaces of the upper and lower baffles of the buffer shell 13, water-passing ramps 132 are respectively provided. The bottom of the water-passing ramp 132 is raised and arranged to transition backward from the front baffle surface 11 of the water retaining box 1, and is arranged in front of the water retaining baffle 34.

[0029] The effect achieved in this way is that the water retaining baffle 34 is in a stored state before and when the equipment enters the water body, and is arranged in contact with the upper and lower baffles of the buffer shell 13; in the process of entering the water body, water flows in from the front baffle surface 11 of the water retaining box 1, and the water ramp 132 can divert the water flow, and when the flipping unit is in action, it can reduce the load of the initial action of the equipment, thereby facilitating the flipping action of the water retaining baffle 34.

[0030] Furthermore, the front blocking surface 11 and the rear blocking surface 12 are centrally located and oppositely provided with assembly holes 5; The anti-collapse support rod 2 comprises a tail wing 22, a rod 23 and a hydrophobic sleeve 21. The tail of the rod 23 is fixedly provided with a tail wing 22. There are at least four tail wings 22, and the four tail wings 22 are evenly arranged in an array around the rod 23. The height of the tail end of the tail wing 22 is flush with the upper and lower edges of the front and rear baffles respectively; The rod 23 is of variable diameter, the outer diameter of the front rod body is set to fit the inner diameter of the assembly hole 5, and its length is equal to the length between the front stop surface 11 and the rear stop surface 12; the rear rod body is larger than the inner diameter of the assembly hole 5; A hydrophobic sleeve 21 is threadedly provided at the end of the rod 23, and the hydrophobic sleeve 21 is in a conical shape; The anti-collapse support rod 2 is inserted from the rear baffle surface 12 to the front baffle surface 11 through the assembly hole 5 and is encapsulated by the hydrophobic sleeve 21 .

[0031] The effect achieved by this is that the tail wing 22 has the functions of supporting, anchoring and water flow diversion at the same time; the water-draining sleeve 21 has the function of diverting water flow during the implementation process; When the plugging device is sunk into the water, the water-repellent sleeve 21 can assist in diverting water flow from the middle of the device to the outside, thereby reducing the impact force on the device. The height of the tail wing 22 is flush with the upper and lower edges of the front and rear baffles respectively. After the blocking device sinks to the bottom of the water, it continues to be impacted head-on by the water flow. The partial anchoring of the tail wing 22 can prevent the box from tilting and assist in guiding the water flow.

[0032] Furthermore, the hoisting member 6 is a hoisting ring, and the hoisting rings are respectively provided in two groups, and are respectively provided on the outer wall of the anti-falling support rod 2 and the buffer shell 13; Each set of lifting rings is provided with at least four, and the arrangement form is arranged in a uniform array around the anti-falling support rod 2 and the buffer shell 13.

[0033] The effect achieved in this way is that any surface of the equipment can meet the lifting conditions.

[0034] When the device is in use, the anti-falling support rod 2 is assembled on the water retaining box 1, and the device is hoisted by a hoisting device; During the sinking process, the front blocking surface 11 and the rear blocking surface 12 are connected; after sinking into the water, the tail wing 22 of the anti-falling support rod 2 is anchored to the bottom of the water to prevent the box from being tilted; The flip unit moves, and the water blocking baffle 34 moves to block the water-through window, completing the breach blocking of a single device; When stacking the devices, the assembly stopper 131 cooperates with the rack 111 of the front stopper surface 11 to form a combined limit between multiple devices.
