Description

Technical Field

[0001] The present invention belongs to the technical field of underwater emergency rescue and disaster relief, and in particular relates to a volute-type firefighting and rescue equipment and method applied to underwater emergency disaster relief. Background Art

[0002] Levees are one of the effective means of flood control. Due to the lack of formal survey and design process in the early stage, some levees have many problems such as poor foundation conditions, poor levee filling quality, and many ponds behind the levees. When the water level is high, it is easy to seepage, diffuse infiltration, and pipe bursting on the back slope, which requires local reinforcement. In some serious cases, there may even be a breach in the levee, resulting in flood overflow, causing huge losses to the safety of people's lives and property. In response to the above-mentioned levee dangers, there are some traditional levee rescue methods, but in actual application, these methods often have certain limitations and disadvantages. Levee rescue is mostly carried out under extreme conditions such as heavy rain and floods. The rescue situation is complicated and time is urgent. Although the rescue rule of "blocking in front and discharging in the back" is followed, the location of the water inlet is difficult to determine when "blocking in front", and the material is easy to be washed away; when "discharging in the back", the pipe burst area is too large and develops too fast, the levee is poorly managed, or there are cavities inside due to biological activities, etc., which may cause the traditional rescue methods to fail. The specific situations can be roughly divided into two categories:

[0003] For the situation where the levee is in danger but the breach has not yet occurred. At this time, the levee has already experienced leakage and overtopping. In this case, the traditional rescue means are mostly to consider using sandbags and other rescue materials to cover the leaks at the upstream slope of the levee, or to raise the dam top and build a sub-dam to avoid the "initial breach" caused by the water flow in the weak place after the flood overtopping. The "initial breach" will expand rapidly and eventually collapse the levee to cause flood disasters. However, before the levee overtopping or breaching occurs, there is still a certain resource dispatching capacity behind the levee, and measures should be taken in time to curb the occurrence of dangerous situations. However, in reality, since the upstream slope leaks are often deeply buried underwater, the location of the leaks is not easy to find, and the water flow upstream of the slope is turbulent, the cover or sandglass used to plug the leaks is often washed away, and for the temporary levee raised or built with sandbags, the flood level often rises too fast, and the speed of raising the sub-levee or the dam top is slow, and the flood is very easy to overflow the levee top and cause damage, and the actual rescue risk is still very high.

[0004] In the case where the dike is in danger and has breached, plugging and rescue technology is the main measure to deal with the breach. Traditional plugging methods include throwing sandbags and stones, wire mesh gabions, steel-wood composite frames, sinking cars and ships, etc. However, for dike breaches under such extreme conditions, traditional plugging and rescue methods require a lot of manpower and material resources in the absence of targeted rescue methods, causing great economic losses. At the same time, plugging and rescue also require on-site guidance from professionals. When the danger occurs in an area with dense dikes, rescue personnel cannot analyze and take corresponding measures in time, and rescue work will also pose a great threat to the personal safety of dike rescue personnel.

[0005] In summary, the modern levee rescue system is relatively mature, but in actual operation, the levee is dangerous and in a remote location. Traditional rescue materials are difficult to mobilize in a short time. The rescue method relies on the "human sea tactics". The large number of rescue personnel required is difficult to quickly reach the disaster site. There is a lack of professional guidance and modern new equipment during the rescue, so only traditional methods can be used. There is a clear gap between the development of modern science and technology and traditional rescue methods. There is an urgent need to develop simple rescue equipment that can be operated by non-professional rescue personnel. Summary of the invention

[0006] In order to make up for the shortcomings of the prior art, the present invention provides a volute type fire rescue equipment and method for underwater emergency disaster reduction. When a breach has not been formed, the water retaining plate is pressed tightly onto the upstream slope of the levee by water pressure, which can quickly block the leakage point of the levee; by splicing multiple devices, the equipment can be stabilized on the upstream side of the levee, and the breach can be quickly blocked by the water retaining plate, thereby improving the rescue efficiency.

[0007] In order to achieve the above object, the technical solution adopted by the present invention is:

[0008] A volute-type firefighting and rescue equipment used for underwater emergency disaster reduction, comprising a carrying platform, the carrying platform being a hollow rigid plate structure; a through-type inflation hole is arranged inside the carrying platform;

[0009] An inflatable rubber bag is provided at the bottom of the carrying platform;

[0010] An expandable water retaining plate is arranged on the top of the carrying platform, and the expandable water retaining plate includes a bottom fixed water retaining pipe segment, a middle windable water retaining pipe segment and a tail weighted steel rod; the bottom fixed water retaining pipe segment is fixed on the top of the carrying platform; the middle windable water retaining pipe segment is fixedly connected to the bottom fixed water retaining pipe segment, and the middle windable water retaining pipe segment is arranged on the top of the carrying platform in a winding manner and is in a volute shape; the tail weighted steel rod is fixed to the end of the middle windable water retaining pipe segment.

[0011] Furthermore, the carrying platform is symmetrically provided with inflation holes, and the bottom of the inflation holes is communicated with the inside of the inflatable rubber bag.

[0012] Furthermore, an air valve is provided at the entrance of the inflation hole.

[0013] Furthermore, a slope fixing ring is provided on one long side of the carrying platform.

[0014] Furthermore, the slope fixing ring is arranged on the side opposite to the deployment direction of the deployable water retaining plate, and one is arranged at each of the left and right ends.

[0015] Furthermore, a clamping nozzle and a clamping slot are respectively arranged on both sides of the long side of the carrying platform.

[0016] A method for using a volute-type fire rescue device for underwater emergency disaster reduction includes two situations: a dike leakage channel has been formed, a dike breach has not yet been formed, and a dike breach has already occurred.

[0017] Furthermore, for the situation where the dike leakage channel has been formed but the dike breach has not yet formed, the specific methods are as follows:

[0018] Place the inflated fire rescue equipment in the river channel, and use a rope to connect the slope fixing ring as a towing rope to quickly tow the fire rescue equipment to the upstream side of the dangerous situation; after determining the approximate location of the leak, fix the rope connected to the slope fixing ring on the embankment slope railing to make the fire rescue equipment float stably on the upstream water surface of the embankment dangerous situation;

[0019] The expandable water retaining plate is pushed and sunk underwater by the drag of the tail weighted steel rod. Under the action of water pressure, the expanded water retaining plate is pressed on the leakage point of the dike. The air valve on the inflation hole is opened to discharge the gas in the inflatable rubber bag, thereby completing the task of plugging the leakage in the dike seepage channel.

[0020] Furthermore, in the case where a dike breach has occurred, the specific methods are as follows:

[0021] In river sections with smooth flow and small water surface fluctuations, multiple volute-type fire-fighting and rescue equipment can be assembled through the nozzles and slots on both sides of the volute-type fire-fighting and rescue equipment; the assembled fire-fighting and rescue equipment is connected to the slope fixing ring through a rope as a traction rope, and dragged to the upstream slope side of the breached river section;

[0022] Fix the firefighting and rescue equipment on the bank slope through the slope fixing ring at the upstream boundary of the river section, and release the rope on the slope fixing ring on the other side. Driven by the water flow, the firefighting and rescue equipment rotates around the fixed side until it collides with the embankment on the downstream side of the breach.

[0023] The slope fixing ring on the downstream side of the breach is quickly fixed to the downstream slope by ropes, so that the rescue equipment is fixed and floats on the water surface upstream of the breach; the expandable water baffle on each volute-type fire rescue equipment is pushed to expand, and the expandable water baffle sinks underwater under the drag of the weighted steel rod at the tail. Under the action of water pressure, the expanded water baffle is pressed against the embankment slope; the air valve on the inflation hole is opened to discharge the gas in the inflatable rubber bag.

[0024] Beneficial effects of the present invention:

[0025] 1) When the breach has not yet formed, the present invention can quickly block the leakage point of the embankment by pressing the water retaining plate against the upstream slope of the embankment through water pressure, effectively solving the problem that it is difficult to determine the location of the leakage point in the early stage of leakage and the leakage point cannot be effectively blocked, thereby increasing the blocking area and the blocking rate;

[0026] 2) The present invention can connect multiple devices to stabilize the devices on the upstream side of the dike to form a narrow and long disaster relief platform to cope with the problem that the length of the dike breach plugging is large and a single device cannot be stabilized on the upstream side of the dike to complete the disaster relief task. The breach is quickly plugged by a water retaining plate, which increases the rescue operation space and improves the rescue efficiency.

[0027] 3) The present invention adopts the design of a volute-type deployable water retaining plate, so that the equipment can be placed on the device when not in use, thereby reducing the volume of disaster relief equipment and materials, increasing the flexibility of the equipment, improving the convenience of using the equipment in disaster relief applications, and improving the efficiency of dike rescue and disaster relief;

[0028] 4) The present invention can fix the unfolded water retaining panel on the upstream slope of the embankment through the fixing ring and the weighted steel rod at the tail of the top water retaining panel, and press the water retaining panel tightly through water pressure to achieve the effect of effectively blocking the leakage point;

[0029] 5) The present invention discharges the gas in the rubber bag so that the bottom of the entire device is closely attached to the slope, thereby increasing the contact area between the water retaining plate and the slope. When a breach has not yet formed, the water seepage channel is blocked, thereby improving the plugging effect; when a breach has formed, the breach can be sealed to the maximum extent, thereby improving the plugging effect and reducing the amount of manual work in the later stage.

DETAILED DESCRIPTION

[0036] The present invention is described in detail below in conjunction with specific implementation modes.

[0037] When a breach has not yet formed, the present invention can quickly block the leakage point of the levee by pressing the water retaining plate onto the upstream slope of the levee through water pressure; by splicing multiple devices, the devices can be stabilized on the upstream side of the levee, and the breach can be quickly blocked by the water retaining plate, thereby improving the efficiency of emergency rescue.

[0038] like Figure 1 , 2 As shown, the volute-type fire rescue equipment for underwater emergency disaster relief of the present invention includes a carrying platform 1, which is a rectangular hollow rigid plate structure; a vertical through-type air-filling hole 8 is arranged inside the carrying platform 1, and the air-filling holes 8 are symmetrically arranged on both sides, and an air valve 7 is arranged at the entrance of the air-filling hole 8; an inflatable rubber bag 9 is arranged at the bottom of the carrying platform 1; the bottom of the air-filling hole 8 is connected to the inside of the inflatable rubber bag 9. When the equipment is needed for rescue, the air-filling hole 8 reserved in the middle area can be relied on to quickly inflate the bag, and after inflation, the air-filling hole 8 is blocked with the air valve 7, so that the equipment can ensure self-stability and float on the water surface.

[0039] A slope fixing ring 2 is arranged on one long side of the carrying platform 1, and the slope fixing ring 2 is arranged on the side opposite to the unfolding direction of the expandable water retaining plate 6, and one is arranged at each of the left and right ends. The slope fixing ring 2 is used to bind the disaster relief equipment to the edge of the embankment slope.

[0040] The top of the carrying platform 1 is provided with an expandable water retaining plate 6, which includes a bottom fixed water retaining plate 3, a middle windable water retaining plate 4 and a tail weighted steel rod 5; the bottom fixed water retaining plate 3 is fixed on the top of the carrying platform 1; the middle windable water retaining plate 4 is fixedly connected to the bottom fixed water retaining plate 3, and the middle windable water retaining plate 4 is arranged on the top of the carrying platform 1 by winding, in a volute shape; the tail weighted steel rod 5 is fixed to the end of the middle windable water retaining plate 4. The two sides of the long side of the carrying platform 1 are respectively provided with a clamping nozzle 10 and a clamping slot 11, and the clamping nozzle 10 is embeddedly connected with the clamping slot 11 for splicing multiple devices.

[0041] The present invention is applied to the method of using the volute type fire rescue equipment for underwater emergency disaster reduction, including two situations: the dike leakage channel has been formed, the dike breach has not yet been formed, and the dike breach has occurred:

[0042] 1) In the early stage of discovering the dike danger, it is mostly because of the leakage channel on the upstream side of the dike, so it is impossible to accurately determine the leakage point. At the same time, the turbulent water flow at the location of the danger is very likely to wash away the rescue materials; the present invention is aimed at the situation where the dike leakage channel has been formed and the dike breach has not yet formed. The specific method is as follows:

[0043] Inflate the inflatable rubber bag 9 at the bottom of the equipment, place the inflated fire rescue equipment in the river, and connect the slope fixing ring 2 with a rope as a traction rope to quickly pull the fire rescue equipment to the upstream side of the dangerous situation; after determining the approximate location of the leak, fix the rope connected to the slope fixing ring 2 to fixed equipment such as the embankment slope railing, so that the fire rescue equipment can stably float on the upstream water surface of the embankment dangerous situation;

[0044] like Figure 5 As shown, push the expandable water baffle 6, which sinks underwater under the drag of the tail weighted steel rod 5. Under the action of water pressure, the expanded water baffle tightly covers the leaking point of the embankment to block the water seepage channel; open the air valve 7 on the inflation hole 8 to discharge the gas in the inflatable rubber bag 9 to complete the task of plugging the seepage channel of the embankment. By discharging the gas in the rubber bag, the bottom of the entire device is closely attached to the slope, increasing the contact area between the water baffle and the slope and improving the plugging effect.

[0045] 2) In view of the fact that the dike is in danger and the dike breach has occurred, considering that the breach will expand rapidly after it is formed, the breach width is large, resulting in a single device without a slope fixing point, and the device cannot be stabilized on the upstream side of the dike, the present invention adopts a disaster relief method of assembling multiple devices for joint operation, and the specific method is as follows:

[0046] like Figure 3 , 4 As shown, in a river section with smooth flow and small water surface fluctuation, multiple volute-type fire-fighting and rescue equipment can be assembled through the nozzles 10 and the slots 11 on both sides of the volute-type fire-fighting and rescue equipment to form a joint application device; the assembled fire-fighting and rescue equipment is connected to the slope fixing ring 2 through a rope as a traction rope, and dragged to the upstream slope side of the breached river section;

[0047] Fix one side of the firefighting and rescue equipment at the upstream boundary of the river section to the bank slope through the slope fixing ring 2, and release the rope on the slope fixing ring 2 on the other side. Driven by the water flow, the firefighting and rescue equipment rotates around the fixed side until it collides with the embankment on the downstream side of the breach.

[0048] The slope fixing ring 2 on the downstream side of the breach is quickly fixed on the downstream slope by a rope, so that the rescue equipment is fixed and floats on the water surface upstream of the breach; the expandable water retaining plate 6 on each volute type fire rescue equipment is pushed to be unfolded, and the expandable water retaining plate 6 sinks underwater under the drag of the tail weighted steel rod 5, and under the action of water pressure, the unfolded water retaining plate is tightly pressed against the embankment slope; the air valve 7 on the inflation hole 8 is opened to discharge the gas in the inflatable rubber bag 9; by discharging the gas in the rubber bag, the bottom of the entire equipment is closely attached to the slope, thereby increasing the contact area between the water retaining plate and the slope, improving the sealing effect, and reducing the amount of manual work in the later stage.

[0049] The specific linkage number of the combined application device is determined by the length of the breach, and is generally longer than the breach by two single device lengths. The combined application device can be stably fixed on the upstream side of the breach, solving the problem that the traditional disaster relief operation surface is limited to the local platform on both sides of the breach, with small space and low efficiency, and it is easy to waste precious rescue time in the early stage of the breach. It increases the rescue operation space and shortens the rescue operation time.

[0050] In the description of the present invention, unless otherwise clearly specified and limited, the terms "set", "install", "connect", "connect", and "fix" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
