Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of safety protection devices, in particular to a safety self-rescue device. Background Art
[0002] In a fire scene, thick smoke is the main cause of death. About 80% of the victims inhaled toxic smoke. These thick smokes are full of highly toxic gases such as carbon monoxide, hydrogen cyanide, hydrogen sulfide, and hydrogen chloride. Hydrogen sulfide is a strong neurotoxin and has a strong irritating effect on mucous membranes. Carbon monoxide is colorless and odorless, and inhalation can cause death due to lack of oxygen in the human body. Hydrogen cyanide is a highly toxic compound that is highly irritating to the eyes and respiratory mucosa. Acute poisoning can cause symptoms such as headaches, dyspnea, and pulmonary edema; chronic poisoning can cause chronic bronchitis, gastric dysfunction, and tooth erosion. These dangerous gas fires pose a threat to the lives of workers, and the safety risks of working in confined spaces are also extremely high.
[0003] At present, the individual protection measures taken in places involving toxic and harmful gases are mainly to wear positive pressure air respirators or chemical protective clothing. Whether it is wearing positive pressure air respirators or wearing heavy or simple chemical protective clothing, it is not conducive to carrying out various work activities and the cost is extremely high. Therefore, the above measures are mainly used for emergency rescue. It is difficult for daily dangerous workers to be effectively protected, and their lives and health are seriously threatened at dangerous moments.
[0004] Some self-rescue devices use mechanical movement, which limits the scope of the operator's working space and has limited usage scenarios. Some self-rescue devices use compressed air, which has high requirements for the working scene and is difficult to maintain. Some devices only have early warning functions and lack self-rescue measures, which still makes it difficult to fundamentally protect the lives of dangerous workers. Utility Model Content

[0025] Example 1
[0026] like Figure 1-2 As shown, this embodiment provides a safety self-rescue device, including a fixing device and a safety belt 2 detachably connected to the fixing device, the fixing device includes a support frame 1 and a pulley block 3 and a fixed pulley guide section 4 installed on the top of the support frame 1, a pulley block 3 is provided with a cable 5, the fixed pulley guide section 4 is used to guide the movement of the pulley block 3, the pulley block 3 is also connected to a motor, a fixed anchor point 6 is provided at the bottom of the support frame 1, and a detection alarm signal device 7 is provided on the safety belt 2.
[0027] The support frame 1 can ensure the stability of the device, help maintain the balance of the device when in use, and prevent tipping due to unstable center of gravity. The fixed anchor point 6 is the fixed base point of the device, which is used to ensure the stability and safety of the entire system. The motor, pulley block 3 and traction rope 5 constitute the physical moving part of the self-rescue device. The fixed pulley guide section 4 can ensure the smoothness and safety of the traction rope 5 during movement, prevent the traction rope 5 from being entangled or knotted, and ensure safety during use. When the operator works in a site with toxic and harmful gases, the support frame 1 is fixed by the fixed anchor point 6, the traction rope 5 is connected to the safety belt 2, and the safety belt 2 is tied to the operator. When the detection alarm signal device 7 detects that the concentration of harmful gases reaches the contact limit value, an alarm signal is issued, the motor is started, and the motor controls the pulley block 3 to rotate. The traction rope 5 on the pulley block 3 guides the moving direction through the fixed pulley guide section 4, and the traction rope 5 moves to transfer the operator to a safe position, thereby achieving the purpose of self-rescue. Among them, the detection alarm signal device 7 can also be used to detect temperature.
[0028] In this embodiment, a UPS power supply 8 is provided on the support frame 1, and the UPS power supply 8 is electrically connected to the motor and the detection alarm signal device 7. The UPS power supply 8 is an uninterruptible power supply, which is used to provide temporary power when the main power supply fails, to ensure that the device is in an effective state at any time, to ensure that the detection alarm signal device 7 and other electronic components can continue to work under any circumstances, and to ensure the operational reliability of the self-rescue device until the rescue is completed.
[0029] In this embodiment, the support frame 1 includes a support rod and a plurality of support rods annularly mounted on the outer circumference of the support rod. There are three support rods, which are connected to form a tripod shape, and each support rod is welded to the support rod, or each support rod is hinged to the support rod. When hinged, the support rod can be rotated so that the support rod is close to the support rod, which can reduce the volume of the support frame, thereby reducing the volume of the device, making it easier to carry and transport the device.
[0030] In this embodiment, the detection alarm signal device 7 is a buzzer alarm. The buzzer alarm has a loud sound, which is convenient for reminding the operator.
[0031] In this embodiment, the safety belt 2 is provided with an air bag 10, and the air bag 10 is connected to an air intake pipe 11, and the other end of the air intake pipe 11 is connected to an oxygen mask 12. When the concentration of harmful gases reaches a certain limit, the oxygen mask 12 can be worn to facilitate the operator to inhale oxygen in the air bag 10 through the air intake pipe 11, thereby preventing the inhalation of a large amount of harmful gases from endangering health and gaining more rescue time. The air bag 10 is fixed to the safety belt 2 by a connector.
[0032] In this embodiment, the support frame 1 is provided with a controller 9, and the controller 9 is respectively connected to the motor and the detection alarm signal device 7. After receiving the data information of the detection alarm signal device 7, the controller 9 processes and analyzes the data to determine whether it is necessary to start self-rescue or other emergency response measures. When the controller 9 reaches the set conditions, it immediately and actively starts the self-rescue work.
[0033] In this embodiment, the safety belt 2 is a five-point safety belt, which is convenient for quick and safe removal of the safety belt 2, and can also ensure the firmness of the connection between the safety belt 2 and the operator.
[0034] Through the unique support frame 1, the UPS power supply 8, controller 9, motor, pulley block 3 and other components are integrated into a portable and compact body, which is convenient for use in limited space operations, fire, temporary power supply and other operating scenarios. At the same time, the device can be fixed in a complex operating environment to provide additional stability and support for the self-rescue device, helping the support frame 1 to maintain balance during use, preventing tipping due to unstable center of gravity, or instability due to sudden movements. Through the motor, pulley block 3, fixed pulley guide section 4, traction rope 5, safety belt 2 and other devices, the rescue device is safely connected to the operator, which does not affect the operator's operation, and can also actively help the operator to move safely or escape in an emergency.
[0035] The working principle of a safety self-rescue device is: the support frame 1 is fixed by a fixed anchor point 6, the rope 5 is connected to the safety belt 2, and the safety belt 2 is tied to the operator. When the detection alarm signal device 7 detects that the concentration of harmful gas reaches the contact limit value, an alarm signal is issued and the danger signal is transmitted to the controller 9. The controller 9 starts the motor, and the motor controls the pulley block 3 to rotate. The rope 5 of the pulley block 3 guides the moving direction through the fixed pulley guide section 4. The rope 5 moves to transfer the operator to a safe position, thereby achieving the purpose of self-rescue.
[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
