Description

Technical Field

[0001] This invention relates to the field of fire rescue equipment technology, specifically a portable intelligent fire demolition and rescue device. Background Technology

[0002] In fire rescue and disaster response, breaching operations are a core component in opening rescue channels and rescuing trapped personnel. Breaching equipment is typically used to cut, expand, prop up, or destroy obstacles such as metal, wood, and concrete, and is widely used in complex rescue scenarios such as fires, earthquakes, and traffic accidents. As rescue environments become increasingly complex, higher demands are placed on the portability, operational efficiency, and multi-functional integration of breaching equipment.

[0003] However, existing conventional demolition equipment still has certain limitations in practical applications. On the one hand, traditional equipment has relatively simple functions, and in the face of complex and diverse rescue scenes, it is often necessary to carry multiple different types of tools, which not only increases the burden and carrying difficulty for rescuers, but also reduces mobility and operational efficiency in confined spaces. On the other hand, in environments with obstructed vision, such as dense smoke, darkness, or obstacles, operators usually have difficulty intuitively grasping the situation behind the demolition point, and lack effective means of sensing vital signs, live lines, and harmful gases. Demolition in blind spots can easily cause secondary disasters. In addition, existing equipment relies heavily on the operator's experience to apply force, and lacks intelligent monitoring and force feedback control of the critical state of demolition. At the moment of penetration, it is easy to cause secondary injury to trapped personnel due to over-impact.

[0004] Therefore, those skilled in the art have provided a portable intelligent fire-fighting demolition and rescue device to solve the problems mentioned in the background art. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a portable intelligent fire-fighting demolition and rescue device, which solves the problems of existing devices having limited functions, resulting in heavy carrying loads, lack of environmental awareness during blind-zone demolition which easily leads to secondary disasters, and lack of torque feedback during demolition penetration which easily causes secondary injuries to trapped personnel.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A portable intelligent fire-fighting demolition and rescue device includes a main body, which contains a main control unit and a power supply module, and an intelligent power module at the front end. The output end of the intelligent power module is connected to a quick-change interface, and a modular working head can be detachably installed on the quick-change interface. The front end of the main body is also provided with a multimodal detection module, and the gripping part of the main body is provided with a haptic feedback handle; The main control unit is electrically connected to the intelligent power module, the multimodal detection module, and the haptic feedback handle, respectively. Through the above technical solutions, the combination of quick-change interface and modular working head enables the equipment to have multi-scenario quick-change operation capability. Combined with the linkage of multimodal detection module and tactile feedback handle, it realizes blind spot detection and early warning and tactile interactive feedback on the basis of single-machine multi-functional integration, which significantly improves the portability of the equipment and the safety of demolition operations.

[0007] Furthermore, the multimodal detection module includes an infrared thermal imager, an ultra-wideband pulse radar, a voltage sensing sensor, and a combustible gas sensor. The infrared thermal imager and the ultra-wideband pulse radar are embedded in the upper part of the main body, and an explosion-proof transparent window is provided in front of them. The voltage sensing sensor and the combustible gas sensor are symmetrically embedded on both sides of the main body, and the probe surface of the combustible gas sensor is flush with the front end surface of the main body and is connected to an air inlet micro-hole. By rationally distributing penetrating imaging sensors and physical environment sensors on the upper part and sides of the main body, a comprehensive three-dimensional detection layout is formed, enabling the detection of vital signs behind the wall and the omnidirectional rapid sampling of electrical and flammable gas hazards on the breached surface. This significantly improves the detection response speed and reliability of multiple types of sensors in harsh breaching environments.

[0008] Furthermore, the quick-change interface includes an outer spline sleeve, an annular electromagnetic locker, and a rotating conductive component located at the output end of the intelligent power module. The tail of the modular working head is provided with an inner spline groove, a locking groove, and a signal spring pin that match the outer spline sleeve. When the working head is inserted, the outer spline sleeve and the inner spline groove cooperate to transmit torque. The annular electromagnetic locker engages with the locking groove to achieve mechanical self-locking. The signal spring pin rotates synchronously with the outer spline sleeve and achieves dynamic electrical connection with the main control unit in the rotating state through the rotating conductive component to complete the working head identification and data communication. Through the above technical solution, high torque transmission is achieved by the cooperation of the outer spline sleeve and the inner spline groove, reliable self-locking is achieved by the ring electromagnetic locker, and dynamic electrical connection is maintained between the signal spring pin and the rotating conductive component in the rotating state. This enables automatic identification of the working head and stable data communication while transmitting mechanical power, which significantly improves the reliability and intelligent adaptability of modular quick change operation.

[0009] Furthermore, the modular working head includes at least four types: shearing head, expansion head, impact head, and annular sawing head. The shearing head and expansion head are equipped with pressure sensors, and the impact head and annular sawing head are equipped with wear-resistant temperature sensors. All of the above sensors communicate with the main control unit through the rotating conductive component in the quick-change interface. Through the above technical solution, by embedding corresponding pressure or temperature sensors in the working head for different types of operations, it is possible to directly collect the force and heat status of the working head interacting with obstacles, thereby achieving accurate perception of the working condition at the end of the demolition and significantly improving the accuracy of the main control unit in adaptive control and overload protection.

[0010] Furthermore, the intelligent power module includes a brushless motor, a planetary gear reducer, and a torque sensor. The output shaft of the brushless motor is connected to the planetary gear reducer, and the output end of the planetary gear reducer is connected to a quick-change interface. The torque sensor is connected in series between the planetary gear reducer and the quick-change interface to collect resistance torque data during the demolition process in real time and feed it back to the main control unit. By using the above technical solution, a torque sensor is connected in series between the reducer and the quick-change interface, enabling it to collect changes in resistance torque during the demolition process in real time and accurately and feed them back to the main control unit. This achieves dynamic monitoring of the demolition resistance status and significantly improves the timeliness and accuracy of the equipment's perception of the critical demolition state.

[0011] Furthermore, the main control unit is equipped with an adaptive control module, and the tactile feedback handle is equipped with an eccentric vibration motor. The adaptive control module receives data from the torque sensor and the built-in sensor of the modular working head. When the torque change rate is detected to exceed the preset threshold, it is determined that the breaking point is about to be penetrated. The adaptive control module controls the brushless motor to slow down and drives the eccentric vibration motor to generate a high-frequency vibration warning. Through the above technical solution, the adaptive control module comprehensively judges the torque change and the force data of the working head, so that it automatically reduces the speed when the demolition is about to penetrate, and generates a tactile warning with the eccentric vibration motor, which effectively suppresses the demolition overshoot trend and provides intuitive reminders to the operators, significantly improving the reliability of preventing accidental injury to trapped personnel when the demolition is about to penetrate.

[0012] Furthermore, the main control unit is also equipped with a safety interlock logic module. When the voltage sensing sensor detects a high-voltage AC electric field within a preset distance of the breach point, or the combustible gas sensor detects that the gas concentration exceeds 10% of the lower explosive limit, the safety interlock logic module forcibly cuts off the power supply circuit of the intelligent power module and locks the equipment. Through the above technical solution, the safety interlock logic module makes logical judgments on the dangerous signals of live electricity and flammable gas, so that it can actively cut off the power supply and lock the equipment when it detects a deadly environmental hazard, thereby achieving hard physical interception of the risk of blind zone demolition and significantly improving the safety of avoiding secondary disasters such as electric shock and explosion during blind zone demolition.

[0013] Furthermore, the side wall of the haptic feedback handle is also provided with a tactical interactive display screen, which is electrically connected to the main control unit and is used to display the detection images of the multimodal detection module, the force curve of the working head, the remaining battery power and safety warning information in real time. The tactical interactive display screen is covered with an explosion-proof tempered glass film. Through the above technical solution, by integrating an explosion-proof tactical interactive display screen on the side wall of the handle, it can intuitively and in real time present detection images, force status and safety warning information, realize the visual centralized feedback of complex sensory information, and significantly improve the intuitiveness of rescuers in obtaining equipment status and surrounding situation in noisy, smoky and other harsh environments.

[0014] This invention provides a portable intelligent firefighting and rescue device. It has the following advantages: 1. This invention provides a portable intelligent fire-fighting demolition and rescue device. By setting up a quick-change interface and modular working head, a single main unit can quickly switch between functions such as cutting, expanding, impacting, and sawing according to the rescue scenario, thereby replacing the traditional combination of multiple single tools and significantly improving the portability, mobility in confined spaces, and overall rescue efficiency at the rescue site.

[0015] 2. This invention provides a portable intelligent fire-fighting demolition and rescue device. By setting up a multimodal detection module and a safety interlock logic module, it can detect vital signs, live cables and flammable gas leaks behind the wall before and during demolition operations. When encountering a hazard source, the device will actively lock itself, realizing early warning and proactive intervention for blind zone demolition risks. This significantly improves the safety protection capability against secondary disasters such as electric shock, explosion and secondary collapse in complex environments.

[0016] 3. This invention provides a portable intelligent fire-fighting demolition and rescue device. By setting up an intelligent power module, adaptive control and tactile feedback system, it can monitor the demolition resistance torque in real time, automatically reduce speed at the critical point of penetrating the obstacle, and remind the operator to reduce force through high-frequency vibration of the handle. This effectively suppresses the tendency of over-rushing during demolition and significantly improves the active safety performance of preventing secondary injury to trapped personnel in the critical state of demolition penetration.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1:

[0020] like Figure 1-7 As shown, this embodiment of the invention provides a portable intelligent fire-fighting and demolition rescue device, mainly including a main body 1, a main control unit 2, a power supply module 3, an intelligent power module 4, a quick-switch interface 5, a modular working head 6, a multimodal detection module 7, and a haptic feedback handle 8. The main control unit 2 and the power supply module 3 are centrally located within the rear cavity of the main body 1, providing core computing power and power distribution for the main body; the intelligent power module 4 is axially arranged at the front end of the main body 1, and its output end is directly connected to the quick-switch interface 5; the multimodal detection module 7 is embedded around the outer periphery of the front end of the main body 1, and the haptic feedback handle 8 is located at the middle and rear gripping position of the main body 1. The main control unit 2 is electrically connected to the intelligent power module 4, the multimodal detection module 7, and the haptic feedback handle 8 through internal wiring harnesses, forming the hardware foundation of the entire device.

[0021] In terms of environmental detection, the multimodal detection module 7 includes an infrared thermal imager 71, an ultra-wideband pulse radar 72, a voltage sensing sensor 73, and a combustible gas sensor 74. The infrared thermal imager 71 and the ultra-wideband pulse radar 72 are mounted side-by-side on the upper part of the main body 1, with an explosion-proof transparent window in front to ensure a clear line of sight and prevent damage to the lens from debris. The voltage sensing sensor 73 and the combustible gas sensor 74 are symmetrically mounted on the left and right sides of the main body 1, with the probe surface of the combustible gas sensor 74 flush with the front face of the main body 1 and featuring an air inlet micro-hole for rapid contact and intake of surrounding gas samples.

[0022] In terms of power and head changing, the intelligent power module 4 includes a brushless motor 41, a planetary gear reducer 42, and a torque sensor 43. The output shaft of the brushless motor 41 is connected to the planetary gear reducer 42, and the output end of the planetary gear reducer 42 is connected to the quick-change interface 5. The torque sensor 43 is connected in series between the planetary gear reducer 42 and the quick-change interface 5. The quick-change interface 5 includes an outer spline sleeve 51, an annular electromagnetic locker 52, and a rotating conductive component 53. The tail of the modular working head 6 is provided with an inner spline groove 54, a locking groove 55, and a signal spring pin 56. The modular working head 6 includes at least four types: a shearing head 61, an expansion head 62, an impact head 63, and an annular sawing head 64. The shearing head 61 and the expansion head 62 are equipped with pressure sensors 65, and the impact head 63 and the annular sawing head 64 are equipped with wear-resistant temperature sensors 66. When the working head is inserted, the outer spline sleeve 51 and the inner spline groove 54 cooperate to transmit rotational torque. The annular electromagnetic lock 52 is engaged in the locking groove 55 to achieve mechanical self-locking. The signal pin 56 rotates synchronously with the outer spline sleeve 51 and establishes a dynamic electrical connection with the main control unit 2 in the rotational state through the rotating conductive component 53 to complete the identification and data communication of the working head. The pressure sensor 65 or the wear-resistant temperature sensor 66 built into the working head also transmits the signal back through this channel.

[0023] In terms of intelligent control and feedback, the main control unit 2 integrates an adaptive control module and a safety interlock logic module. The haptic feedback handle 8 contains an eccentric vibration motor 81, and a tactical interactive display screen 9 is located on the side wall. The tactical interactive display screen 9 is covered with an explosion-proof tempered glass film and is electrically connected to the main control unit 2.

[0024] Working Principle: Rescue personnel select the corresponding modular working head 6 according to the needs of the site, align the inner spline groove 54 at its tail with the outer spline sleeve 51 at the front of the main body 1, and insert it. At this time, the signal pin 56 contacts the rotating conductive component 53 to establish an electrical connection, and the main control unit 2 reads the working head's identification information. Subsequently, the annular electromagnetic locking device 52 is energized, and its locking block is pushed into the locking groove 55 to complete the mechanical self-locking, and the equipment enters the standby state. Before and during the operation, the infrared thermal imager 71 and the ultra-wideband pulse radar 72 emit signals through the explosion-proof transparent window to the back of the demolition point to detect vital signs behind the wall. The voltage sensing sensor 73 and the combustible gas sensor 74 sample the environmental status in real time through the air intake micro-holes on both sides. When the voltage sensing sensor 73 detects a high-voltage AC electric field within a preset distance of the demolition point, or the combustible gas sensor 74 detects that the gas concentration exceeds 10% of the lower explosive limit, the safety interlock logic module is triggered, forcibly cutting off the power supply circuit of the intelligent power module 4, locking the equipment to avoid the risk of electric shock or explosion. During normal demolition, the power of the brushless motor 41 is amplified by the planetary gear reducer 42 and transmitted to the quick-change interface 5, driving the modular working head 6 to operate. During this process, the torque sensor 43 collects resistance torque data in real time, and the pressure sensor 65 or wear-resistant temperature sensor 66 inside the modular working head 6 also collects end-point operating signals. When the adaptive control module detects that the torque change rate exceeds a preset threshold and determines that the demolition point is about to be penetrated, the adaptive control module controls the brushless motor 41 to slow down, while simultaneously driving the eccentric vibration motor 81 to generate high-frequency vibration, reminding the operator to reduce force to prevent overshoot and accidental injury to trapped personnel. At the same time, the detection images, force curves, battery level, and early warning information are displayed on the tactical interactive display screen 9, assisting rescue personnel in completing safe demolition operations in complex environments.
