Description

Technical Field

[0001] The present invention relates to the technical field of emergency rescue, and in particular to a remote dismantling device and method for emergency rescue. Background Art

[0002] Emergency rescue equipment refers to equipment specifically used for emergency rescue at various disaster sites. After a disaster occurs, whether effective emergency rescue equipment can be used to carry out rescue within the optimal rescue time is the key to the effectiveness of rescue implementation. Therefore, emergency rescue operations urgently need various advanced emergency rescue equipment.

[0003] During the occurrence of disasters such as earthquakes and mine gas explosions, buildings often collapse, and during the collapse, people are often injured or trapped. Therefore, timely and effective removal of collapsed obstacles in the corresponding emergency rescue activities to rescue trapped people is conducive to improving rescue efficiency and increasing the possibility of survival, which is of great significance.

[0004] At present, emergency rescue equipment technology is constantly innovating and has achieved rapid development. However, in the current emergency rescue process, the following three factors greatly affect the rescue efficiency:

[0005] First, the obstacles created by the collapse of buildings vary in size. For example, relatively strong beams such as concrete floors, cement columns or steel beams tend to be less broken during the collapse process. On the one hand, this may create a living space for the trapped people; on the other hand, in order to rescue the trapped people in time, they need to be broken and removed, which poses a challenge to the rescue work.

[0006] Second, after a disaster occurs, the on-site conditions are often extremely bad, and large-scale mechanized rescue equipment needs to be cleared from the periphery and gradually enter, but the distribution of the trapped people is uncertain, and the trapped people in the disaster center are often in a higher degree of danger;

[0007] Third, disasters are often accompanied by secondary disasters such as floods and fires, which greatly limit the scope of applicable crushing and demolition technologies.

[0008] In the current rescue work, traditional crushing and demolition equipment such as hydraulic pliers, breakers and cutting machines still account for a large proportion. Their shortcomings of low work efficiency and high labor intensity seriously restrict the efficiency of rescue work. However, due to the above three factors, a large number of advanced technologies still cannot be effectively applied on site. The reason is that due to the limitations of the use environment, equipment size, weight and movement methods, the equipment has poor adaptability and cannot meet the needs of rescue work.

[0052] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0053] The purpose of the present invention is to provide a remote dismantling device and method for emergency rescue, so as to improve the rescue efficiency.

[0054] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0055] The embodiments of the present invention first explain the technical terms involved in the present invention, which are as follows:

[0056] Emergency rescue: Emergency rescue generally refers to the activities and plans for prevention, preparation, response and recovery of sudden and destructive emergencies. According to the different types of emergencies, it is divided into emergency rescue in the fields of health emergency, traffic emergency, fire emergency, earthquake emergency, factory emergency, and family emergency. The emergency rescue involved in this case specifically refers to emergency rescue activities that require demolition work.

[0057] Remote demolition: In this case, remote demolition means that the main energy source and control system can be far away from the object to be demolished to adapt to the harsh working environment during emergency rescue work and the situation where it is inconvenient for large demolition equipment to enter and exit, but the execution device still needs to be in contact with the object to be demolished.

[0058] Based on the technical problem, the present invention provides a remote demolition device and method for emergency rescue. The embodiment of the present invention uses electric energy as the main energy source, and according to the characteristics of the object to be crushed, the electric energy is converted into heat energy or pressure wave impact energy through an energy conversion device to achieve the crushing of the object. The main feature is that the energy source and the execution end that directly realizes the crushing are arranged separately, and are only connected through the cable in the cable assembly; the control end is more flexible, and the control end can be arranged on the energy source side or the execution end side according to the needs of the site.

[0059] like Figure 1 As shown, the removal device includes a mobile device 6, and a control system 1, an energy management system 5, an energy conversion device 2, a cable assembly 3 and an execution end 4 arranged on the mobile device 6;

[0060] The control system 1 is connected to the energy management system 5 and the energy conversion device 2 respectively; the energy management system 5 is connected to the energy conversion device 2, one end of the cable assembly 3 is connected to the energy conversion device 2, and the other end of the cable assembly 34 is connected to the execution end; the energy conversion device 2 is used to convert the first electric energy output by the energy management system 5 into the second electric energy required by the execution end 4; the execution end 4 is used to break the broken objects at the rescue site.

[0061] The control system 1 is a device for realizing remote control of the demolition and crushing process, and is a key component for interacting between the energy management system 5 and the energy conversion device 2. It is necessary to determine the crushing method according to the crushing object, so as to select different energy input and conversion methods. In this example, there are two methods to choose from: high-pressure impact crushing and hot melt crushing. In the embodiment of the present invention, the control system includes a box, a control panel, a device switch, and a cable. The bottom of the box is fixed inside the mobile system, the control panel is connected to the outer wall of the mobile system through the outer wall of the box, the device switch is connected to the outer wall of the box, and the control system is connected to the energy management system and the energy conversion device through a cable. The voltage of the energy conversion device and the energy management system is controlled by the control panel of the control system. Specifically, a control signal is sent to each unit through the touch screen of the control panel, and the feedback signal returned by each unit is processed and fed back to the touch screen through the signal amplifier, so that the energy conversion device and the energy management system can be controlled, and multiple safety protection functions such as overcurrent, overvoltage, and leakage are built in.

[0062] Energy conversion device 2: Energy conversion device 2 is the core component for realizing the conversion of electrical energy into thermal energy or impact energy. In the embodiment of the present invention, the energy conversion device 2 can realize two working modes: hot melting and impact crushing, which can be switched according to the crushing requirements. The basic principle of these two energy conversion methods is that a large amount of heat energy is generated when a large current passes through a resistor, thereby causing the temperature of the resistor to rise. The difference is that the hot melting method mainly relies on the heat energy generated when a large current passes through a resistor (such as a steel cage inside the crushing object). When its temperature exceeds the temperature that the resistor can withstand, the resistor melts and is destroyed. At the same time, the heat radiation and heat conduction in this process will also cause thermal damage to the surrounding area of ​​the resistor (such as concrete), thereby facilitating subsequent crushing. Impact crushing is to cause the resistor to melt and expand rapidly when a large current passes through it instantly, thereby pushing the surrounding medium to move outward to generate a shock wave, thereby generating an impact destructive force. Therefore, the design of the energy conversion device must meet the requirements of outputting instantaneous peak current and continuous large current, and at the same time, it must be able to withstand high temperature and high voltage. The energy conversion device 2 as a whole includes three parts: a transformer module (i.e., a transformer), a capacitor energy storage module (i.e., an energy storage capacitor) and a control unit. In the embodiment of the present invention, the energy conversion device 2 is connected to the control panel and the cable assembly. The transformer module and the capacitor energy storage module form a voltage doubling rectifier circuit to jointly realize the high-voltage charging process. The 220V or 380V AC generated in the energy control system is converted into high-voltage DC through the transformer module and then stored in the capacitor energy storage module. The output voltage is determined by the charging time (i.e., the preset time), which is input into the control unit through the control system for adjustment. The capacitor energy storage module is mainly a group of coaxial capacitors. By utilizing its coaxial output characteristics and small loop inductance, the output waveform can have the characteristics of large discharge current and steep rise time.Specifically, the energy conversion device includes a transformer, an energy storage capacitor, a first controllable switch, a second controllable switch and a control unit; the primary side of the transformer is connected to the energy management system, one end of the secondary side of the transformer is connected to one end of the energy storage capacitor through the first controllable switch, and the other end of the secondary side of the transformer is connected to the other end of the energy storage capacitor, and the transformer is used to charge the energy storage capacitor after boosting the first electric energy; one end of the energy storage capacitor is connected to one end of the first cable in the cable assembly through the second controllable switch, and the other end of the energy storage capacitor is connected to one end of the second cable in the cable assembly; the control end of the first controllable switch and the control end of the second controllable switch are both connected to the control unit; the control unit is used to control the first controllable switch to close for a preset time when it is necessary to break; the control unit is also used to control the second controllable switch to open and close at a preset frequency after the preset time to output the second electric energy in the form of high-frequency pulses or control the second controllable switch to close to output the second electric energy in the form of transient high voltage; the control unit is also connected to the control system, and through interaction with the control system, obtains the preset time from the control system and feeds back the current state of the energy conversion device to the control system.

[0063] The cable assembly 3 is an important component connecting the energy conversion device and the execution end. In order to achieve remote crushing, the cable assembly adopts a large-capacity release and recovery fully automatic winch during the design process, and adopts a double-drum structure to carry the cables (including the first cable and the second cable) connecting the two ends of the energy conversion device and the two ends of the execution end. In order to be used in a fire-related rescue environment, the cable is selected as a high-temperature flame-retardant cable, which must meet the flame temperature of 950℃~1000℃ required by the A-level fire protection experiment in the industry standard GB12666.6 and the operation requirements under the conditions of continuous fire supply time of 90min. In order to be used in a wading rescue environment, all interfaces need to be sealed, and the relevant electrical connectors adopt the IP68 protection requirements in the shell protection level of GB / T4208-2017. In an embodiment of the present invention, the execution end 4 is connected to the energy conversion device 2 through a cable. Specifically, in a first embodiment, the cable assembly 3 includes a drum, a first cable and a second cable, and the first cable and the second cable are wound on the drum in parallel. Or in a second embodiment, the cable assembly 3 includes two drums, a first cable and a second cable, and the first cable and the second cable are wound on the two drums respectively.

[0064] The execution end 4 is a direct functional component for crushing the crushed object, and its specific structure can be customized according to the crushed object. Figure 2 There are two standard options shown, Figure 2(a) is used for crushing metal skeletons such as steel cages and channel steel. When the hot melt method is used for crushing, the energy conversion device outputs high-frequency alternating current. By winding the execution end around the expected crushing object, thermal crushing is achieved through eddy current heating. The mechanism is required to withstand high temperature and high voltage. Figure 2 (b) shows a sealed electrode assembly that can generate an instantaneous high-voltage shock wave under the action of a high-voltage pulse current. The interior includes electrodes, arc wires, and electrolytes. During the design process, it is necessary to ensure that the arc wires will instantly melt and generate a high-voltage shock wave under the action of an instantaneous high voltage, and the external sealing cylinder should minimize its damping effect on the shock wave while ensuring the sealing performance, so as to ensure that the shock wave acts on the crushed object as much as possible. In the embodiment of the present invention, Figure 2 Both ends of the actuator in the connector are connected to the cables in the cable assembly.

[0065] The energy management system 5 provides the required energy for the demolition device to achieve hot melting or crushing impact. During the demolition process, if the hot melting function is used, the power demand is often large; if the impact crushing function is used, although the instantaneous current is large, the power demand is relatively small due to the short discharge time. Figure 1 As shown, in this embodiment, the energy management system 5 adopts two energy supply modes: generator power supply and external power grid direct plug-in power supply. Except that the hot melt mode must be adopted and the external power supply mode must be adopted when the power exceeds the rated power of the generator, the actual working mode can be optimized according to the on-site working conditions. In the embodiment of the present invention, the control end of the energy management system is connected to the control system 1. Specifically, the energy management system 2 includes: a power cord and a generator; one end of the power cord is used to connect to an external power supply, and the other end of the power cord is connected to the energy conversion device 2; the generator is connected to the energy conversion device 2; a first switch module is arranged between the other end of the power cord and the energy conversion device 2; a second switch module is arranged between the generator and the energy conversion device 2, and the control end of the first switch module and the control end of the second switch module are both connected to the control system.

[0066] The mobile device 6 is an important component to ensure the mobility of the device involved in this example. This embodiment preferably uses a box truck as the mobile device 6 of the demolition device. Its flexible movement can ensure that during the rescue process, the device is as close to the rescue location as possible to expand the scope of rescue operations; the use of a closed box structure can improve the system's adaptability to the complex and harsh environment of the rescue site. In an embodiment of the present invention, the mobile device 6 includes a vehicle body and a box body, wherein the control system, energy conversion device, energy management system, and cable assembly are fixed at the bottom inside the mobile system box body, and the box body is provided with movable doors at the energy conversion device, control system, and cable assembly. During operation, the movable doors are opened to perform operations such as cable access and use of the control system.

[0067] like Figure 3 As shown, an embodiment of the present invention further provides a remote dismantling method for emergency rescue, the dismantling method is applied to the above-mentioned dismantling device, and the dismantling method comprises the following steps:

[0068] The execution end is set at the broken object at the rescue site;

[0069] Determine whether there is a power supply at the rescue site, and obtain a first determination result;

[0070] If the first judgment result indicates yes, one end of the power line in the energy management system is connected to the power supply, and the first switch module in the energy management system and the first controllable switch in the energy conversion device are closed;

[0071] If the first judgment result indicates no, starting the generator in the energy management system, and closing the second switch module in the energy management system and the first controllable switch in the energy conversion device;

[0072] Determine whether the crushed object is a metal component, and obtain a second determination result;

[0073] If both the second judgment result and the first judgment result indicate yes, a first operation is performed; the first operation is: after the first controllable switch is closed for a preset time, the second controllable switch in the energy conversion device is controlled to open and close at a preset frequency;

[0074] If the second judgment result indicates yes and the first judgment result indicates no, then when the power required for breaking the broken object by the hot melt method is not greater than the power generated by the generator, the first operation is performed, and when the power required for breaking the broken object by the hot melt method is not greater than the power generated by the generator, the second operation is performed; the second operation is to control the second controllable switch in the energy conversion device to close after the first controllable switch is closed for a preset time;

[0075] If the second judgment result indicates no, then the second operation is performed.

[0076] The breaking device and method provided by the embodiments of the present invention can be applied to the following scenarios:

[0077] 1) Used for emergency rescue after gas, natural gas, and chemical product explosions

[0078] At present, gas, natural gas, and chemical product explosions occur frequently, and the occurrence of explosions is often accompanied by the occurrence of fires. At present, in the limited space caused by such accidents, large mechanical tools cannot quickly enter, remove related obstacles, and rescue trapped persons. The technical means relied on for emergency rescue are still relatively limited. Rescue is mainly carried out manually using traditional demolition equipment. The equipment is often heavy, but the operating efficiency is low. Working in a high temperature and dense smoke environment for a long time will also cause serious harm to the operators and trapped persons. The demolition device involved in the embodiment of the present invention adopts a high-temperature flame-retardant cable, which is flexible and easy to reach the scene. During the construction process, it is only necessary to drill blasting holes or break the surface of the demolition object to expose the internal metal components for easy clamping in the hot melt mode, and the labor intensity of the work is low.

[0079] 2) Used for emergency rescue of natural disasters such as earthquakes

[0080] When natural disasters such as earthquakes occur, the affected area is relatively large, and the disaster center is often the most dangerous and the location where trapped people need timely assistance. However, once a disaster occurs, large rescue equipment can only start from the periphery of the disaster area and enter slowly due to its poor mobility, which seriously affects the rescue efficiency. The demolition device involved in the embodiment of the present invention can make full use of the flexibility of the cable and greatly increase the operating range, thereby assisting rescue personnel to enrich demolition methods and improve rescue efficiency.

[0081] 3) Other occasions involving crushing and demolition

[0082] The demolition device and method involved in the embodiments of the present invention can not only be applied to the field of emergency rescue, but can also be promoted for use in other similar occasions where building demolition is required but it is not convenient for large demolition equipment to enter or explosive blasting is used, such as mine rescue.

[0083] The remote demolition device for emergency rescue involved in the present invention integrates knowledge of various disciplines such as mechanics, electricity, fluid, force, heat, wave, and materials, and utilizes the characteristics of simple and efficient transmission of electric energy, the principle that electric energy can be converted into heat energy and impact energy, and separates the energy source from the execution end, thereby achieving the purpose of remote crushing and demolition. This technology greatly increases the operating radius, enriches the technical means of crushing and demolition in emergency rescue, and improves rescue efficiency.

[0084] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0085] The principles and implementation methods of the present invention are described in this article using specific examples. The description of the above embodiments is only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
