Description

Technical Field

[0001] This invention relates to the field of fire-fighting equipment technology, and in particular to a fire-fighting cart with personnel protection function. Background Technology

[0002] Fire trucks, also known as fire engines, are vehicles designed and manufactured to be suitable for firefighters, equipped with various firefighting equipment or extinguishing agents, and used by fire brigades for firefighting, assisting in firefighting, or fire rescue. In most countries, including China, fire departments also use them for other emergency rescue purposes. Fire trucks transport firefighters to disaster scenes and provide them with various tools for carrying out rescue missions. When a fire is indoors or in a relatively confined area, large firefighting equipment cannot reach the vicinity of the fire, necessitating the use of smaller fire trucks.

[0003] When using small fire trucks, if the water tank, water pump, battery, and other equipment are too small, the firefighting effect will be poor, and the stored water may be used up without successfully extinguishing the fire. If the water tank is too large, it will increase the weight of the small fire truck itself, making it extremely tiring for firefighters to push the truck. Most importantly, in the case of high temperature, lack of oxygen, and toxic gases at the fire scene, and even the possibility of burning materials falling off, existing fire trucks have focused more on firefighting effectiveness, but have not given much consideration to the functions and structures that ensure the safety of firefighters, thus putting firefighters themselves at great risk.

[0004] An invention patent with publication number CN106730521A discloses a mobile fire truck, including a box body. Universal wheels are evenly distributed at the four corners of the lower end of the box body. A push rod is provided on one side of the box body, and a crossbar runs through one side of the push rod.

The first connecting rod 19 is rotatably connected to a second connecting rod 20. The middle part of the second connecting rod 20 is connected to the vehicle platform 1 through a column. A hand handle 21 is disposed at the end of the second connecting rod 20 away from the first connecting rod 19. A button 22 for controlling the switch of the fire pump 4 is disposed on the hand handle 21.

[0028] When in use, the trolley, water tank 3, fire pump 4, and sprinkler head 5 work together to ensure normal indoor fire fighting. The numerous protective devices 8, including head protection 9, hand protection 10, foot protection, high temperature protection device 118, and smoke protection device 128, can address various possible injuries to operators in a fire scene from the perspectives of head, hand, foot, smoke, and temperature. When in use, firefighters can put this device on their heads, with the shoulder support 15 resting against their shoulders. Their limbs and all four limbs are wrapped in the fireproof cloth 16. In this way, when debris falls from above, the top cover 13 can prevent firefighters from being injured by falling objects. The springs on the shoulder support 15 can ensure the cushioning of falling objects and prevent firefighters from being injured in the head. The hands are inside the fireproof cloth 16, which firstly isolates them from heat and open flames, and secondly allows for flexible operation of the hand lever 21. Through the first link 19 and the second link 20, the nozzle 5 can be moved within a small range. Combined with the push handle 6 to control the vehicle body fire line, it can achieve the function of easy fire extinguishing. The button 22 on the handle can turn the water pump on and off at any time to save water.

[0029] Combined with appendix Figure 2The foot protection unit includes a cleaning water pipe 23 disposed on the side of the vehicle platform 1. The cleaning water pipe 23 has several cleaning holes 24. The cleaning water pipe 23 is connected to the water tank 3 via a high-pressure pump 25 and is inclined downwards at a 45° angle. A pedal 26 is disposed on the side of the push handle 6 on the vehicle platform 1. The pedal 26 can control the switch of the high-pressure pump 25. The high-temperature protection device 118 includes a cooling pipe 27 disposed on one side of the top cover 13. The cooling pipe 27 is connected to the water tank 3 via a water pump. Several through holes are disposed on one side of the cooling pipe 27. The dust protection device 128 includes an air filter 28 mounted on the vehicle platform 1. The air filter 28 is connected to the head protection device 8 via a corrugated pipe 29, and the corrugated pipe 29 is provided with several support rings 30 on its exterior. A support frame 31 is mounted on the vehicle platform 1, and a lighting lamp 32 is mounted on the support frame 31.

[0030] When this device is in use, if there is a lot of debris on the ground, stepping on pedal 26 will cause water from the cleaning pipe 23 to spray out from the cleaning hole 24. The high-pressure water jet generated by the high-pressure pump 25 can cool down or directly wash away the hot debris on the ground, preventing injury to firefighters' feet from excessively high ground temperature or debris. Stepping on pedal 26 again after use will turn it off. The switching principle is existing technology and will not be elaborated here. The cooling pipe 27 can spray water on the back of firefighters during use to ensure their body temperature does not become too high. It can also control the temperature inside the fireproof cloth 16 and the top cover 13, thus ensuring that firefighters are not harmed by excessive heat. The air filter 28 and corrugated pipe 29 ensure that firefighters breathe dust-free and heat-free air in the fire scene, thus ensuring their breathing safety. The lighting 32 ensures the firefighters' visibility.

[0031] The working principle of this embodiment is as follows: the trolley, water tank 3, fire pump 4 and nozzle 5 work together to ensure the completion of normal indoor fire fighting work. The various protective devices 8, including head protection 9, hand protection 10, foot protection, high temperature protection device 118 and smoke protection device 128, can solve various possible injuries to operators in the fire scene from the perspectives of head, hand, foot, smoke and temperature. When in use, firefighters can put this device on their heads, with the shoulder support 15 resting against their shoulders. Their limbs and all four limbs are wrapped in the fireproof cloth 16. In this way, when debris falls from above, the top cover 13 can prevent firefighters from being injured by falling objects. The springs on the shoulder support 15 can ensure the cushioning of falling objects and prevent firefighters from being injured in the head. The hands are inside the fireproof cloth 16, which firstly isolates them from heat and open flames, and secondly allows for flexible operation of the hand lever 21. Through the first link 19 and the second link 20, the nozzle 5 can be moved within a small range. Combined with the push handle 6 to control the vehicle body fire line, it can achieve the function of easy fire extinguishing. The button 22 on the handle can turn the water pump on and off at any time to save water.

[0032] When there is a lot of debris on the ground, stepping on pedal 26 will cause water from the cleaning pipe 23 to spray out from the cleaning hole 24. The high-pressure water jet generated by the high-pressure pump 25 can cool down or directly wash away the hot debris on the ground, preventing injury to firefighters' feet from excessively high ground temperature or debris. Stepping on pedal 26 again after use will turn it off; the switching principle is existing technology and will not be elaborated here. The cooling pipe 27 can spray water on the backs of firefighters during use to ensure their body temperature does not become too high. It can also control the temperature inside the fireproof cloth 16 and the top cover 13, thus ensuring that firefighters are not harmed by excessive heat. The air filter 28 and corrugated pipe 29 ensure that firefighters breathe dust-free and heat-free air in the fire scene, thus ensuring their breathing safety.
