Description

Technical Field

[0001] This utility model relates to the field of coal mine fire protection production technology, specifically a mobile fire extinguishing device for coal mines. Background Technology

[0002] Coal mining machinery is a broad category of machinery. It is specifically designed for coal mining and differs from other mining machinery due to its specialized characteristics. As a major coal producer, China's annual coal production is constantly increasing. Coal mine fire extinguishing refers to the suppression of coal mine fires. Any fire requires the simultaneous presence of combustibles, air supply, and a heat source; none of these can be lacking. Furthermore, due to the complex environment underground, foam fire extinguishers are mostly used.

[0003] Most current mobile foam fire extinguishers use a vehicle to carry a foam tank, connected to a water source via an external pipe. The overall mobility of the equipment is limited by the location of the water source and the length of the pipe. At the same time, the position of the foam spraying device is relatively fixed, with poor adjustability and limited foam coverage. It is necessary to rely on the natural flow of the foam mixture to cover the burning material for fire extinguishing, and there is still room for improvement in work efficiency.

[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0045] Please see Figure 1-4 In this embodiment of the present invention, a mobile fire extinguishing device for coal mines includes a storage structure 1, a spraying structure 2, and a steering structure 3. The storage structure 1 includes a water tank 104, and a foam tank 105 is fixedly installed on the front side of the water tank 104. The spraying structure 2 includes a first rotating seat 201, which is fixedly installed on the upper surface of the foam tank 105. The steering structure 3 includes a second support rod 301, which is fixedly installed on the upper surface of the foam tank 105. A second hinge seat 302 is rotatably installed on the upper end of the second support rod 301, and the second hinge seat 302 is hinged to the bottom side of the control rod 303.

[0046] Specifically, by integrating the water storage tank 104 and the foam tank 105 together, the water source can be supplied independently without the need for external water supply pipelines. This eliminates the limitation of pipeline length and enables the entire device to move freely underground, greatly improving its protection range against fire. At the same time, the vertical rotation of the upper and lower ends of the second hinge seat 302 allows the control rod 303 to rotate freely within a certain range in both the horizontal and vertical directions. The control rod 303 can be used to control the direction of the spray structure 2, allowing the direction of foam spray to be freely adjusted within a certain range without moving the overall orientation of the device. This effectively increases the coverage area of ​​the fire-extinguishing foam and improves the fire-extinguishing effect.

[0047] Example 1

[0048] like Figure 2 As shown, in this embodiment, the storage structure 1 also includes a platform 101 and a first handle 103. Wheels 102 are fixedly installed at the four corners of the bottom side of the platform 101; the first handle 103 is fixedly installed on the rear edge of the upper surface of the platform 101.

[0049] In this embodiment, the first handle 103 applies force to the vehicle platform 101, and the wheels 102 roll to support the vehicle platform 101, which carries the overall equipment structure and moves it, making it convenient to move to the fire site for firefighting work.

[0050] like Figure 2-3 As shown, in this embodiment, the storage structure 1 further includes a tank support 106, a water inlet 107, a water outlet 108, a water inlet valve 110, a three-way pipe 111, a pressure pump 109, and a liquid outlet valve 112. There are several tank supports 106, which are fixedly installed on the upper surface of the vehicle platform 101 and respectively fixedly installed on the bottom sides of the water storage tank 104 and the foam tank 105. The water inlet 107 is fixedly installed on the upper surface of the water storage tank 104. The water outlet 108 is fixedly installed on one side of the water storage tank 104. The water inlet valve 110 is fixedly installed on one side of the foam tank 105. One end of the three-way pipe 111 is fixedly connected to the water inlet valve 110, and the three-way pipe 111 is interconnected with the water outlet 108 via a pipe. The pressure pump 109 is connected to the three-way pipe 111 and the water inlet valve 110 via a pipe. The channels are interconnected; the outlet valve 112 is fixedly installed on the other side of the foam tank 105; the spray structure 2 also includes a first hinge seat 202, a first support rod 203, a proportioning mixer 204, a spray nozzle 205, a first hose 206, and a second hose 207. The first hinge seat 202 is rotatably installed on the upper surface of the first rotating seat 201 via a bearing; the lower end of the first support rod 203 is hinged to the first hinge seat 202; the proportioning mixer 204 is fixedly installed on the upper end of the first support rod 203; the spray nozzle 205 is fixedly installed at the front end of the proportioning mixer 204; the first hose 206 is fixedly installed on one side of the proportioning mixer 204, and the other end of the first hose 206 is interconnected with the outlet valve 112; the second hose 207 is fixedly installed on the rear side of the proportioning mixer 204, and the other end of the second hose 207 is interconnected with the three-way pipe 111.

[0051] In practice, the water in the first handle 103 is pressurized by the pressurizing pump 109 and directed to the three-way pipe 111. A portion of the water is diverted into the foam tank 105, where it mixes with the agent to form a foam liquid. The foam liquid is then injected into the proportioning mixer 204 through the first hose 206, while another portion is directly introduced into the rear end of the proportioning mixer 204 through the second hose 207. The foam liquid forms foam in the proportioning mixer 204 and mixes with the water introduced through the second hose 207 to form a foam mixture. The mixture is then sprayed out under water pressure, providing a certain range and enabling foam spraying to extinguish fires far from the source, thus ensuring the safety of personnel.

[0052] Example 2

[0053] Based on Embodiment 1, this invention supplements the specific method of adjusting the spray direction of the spray structure 2 through the adjusting structure 3, which was not mentioned in Embodiment 1.

[0054] like Figure 4 As shown, in this embodiment, the directional adjustment structure 3 further includes a telescopic rod 310, a second handle 311, a folding rod 304, a compensating slide rod 306, a third hinge seat 308, and a second rotating seat 309. The telescopic rod 310 is slidably sleeved on the rear end of the control rod 303; the second handle 311 is fixedly installed on the rear end of the telescopic rod 310; the folding rod 304 has compensating slide grooves 305 in both the vertical direction at the rear end and the two sides at the front end; there are two compensating slide rods 306, which are slidably engaged with the two compensating slide grooves 305 respectively, and are fixedly installed on one end of the control rod 303 and one end of the connecting rod 307 respectively; the third hinge seat 308 is hinged to one end of the connecting rod 307; the upper side of the second rotating seat 309 is hinged to the third hinge seat 308 through a bearing, and the second rotating seat 309 is fixedly installed on the rear edge of the upper surface of the proportioning mixer 204.

[0055] In practice, when spraying the foam mixture, the telescopic rod 310 is pulled out from the folding rod 304, and the second handle 311 is brought close to the operator. At the same time, the lever arm length of the rear half of the control rod 303 is extended to reduce the burden when adjusting the spray structure 2. The rear end of the control rod 303 can be freely rotated horizontally and vertically through the second handle 311, which causes the front end of the control rod 303 to drive the rear end of the folding rod 304 to rotate in the opposite direction. Then, the front end of the folding rod 304 is used to push the rear end of the spray structure 2 to rotate in the same direction through the third hinge seat 308 and the second rotating seat 309, thereby rotating the spray nozzle 205, adjusting the spray direction, and increasing the foam coverage area.
