[0027] 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.
[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0029] Referring to Figures 1-3, this utility model provides a fire extinguishing device for mines, comprising:
[0030] The frame structure 1 has an electric walking wheel assembly installed at its bottom and a control system installed on it; in this embodiment, the control system uses a PLC or a microcontroller.
[0031] Liquid storage tank 2 is installed on the top of frame structure 1, and a pump assembly is installed at the bottom of liquid storage tank 2;
[0032] Support 3 is installed on the side wall of frame structure 1, and two symmetrically arranged translation components are installed on support 3;
[0033] Bottom spray arm assembly, the bottom spray arm assembly is fixedly installed at the bottom of bracket 3, and the bottom spray arm assembly is connected to the pump assembly;
[0034] A central sleeve is fixedly installed on bracket 3 at its center. The central sleeve is connected to the pump liquid assembly. Extended spray arm assemblies are slidably connected to both sides of the central sleeve, and the extended spray arm assemblies are connected to the central sleeve.
[0035] Among them, the two central sleeves are fixedly connected to the moving ends of the two translation components respectively, and the electric walking wheel assembly, the pump assembly, and the translation assembly are all electrically connected to the control system.
[0036] With this configuration, the present invention can spray and extinguish fires in the area below the device through the bottom spray arm assembly; while the extended spray arm assembly is slidably connected to the central sleeve, and the two extended spray arm assemblies are driven to slide along the central sleeve by two sets of translation components, so that they can move to one side or both sides according to the actual fire extinguishing needs. The position of the extended spray arm assembly can be flexibly adjusted according to actual needs, thereby expanding the spray range and fire extinguishing coverage, realizing fire extinguishing in a larger area of the mine, and improving the fire extinguishing effect.
[0037] This invention controls the start and stop of the electric walking wheel assembly through a control system, enabling it to automatically move to the fire scene without manual handling or operation, thus shortening the time to reach the fire source. The control system also controls the output power of the pump assembly and the translation assembly, thereby controlling the spray intensity and range of the spray arm assembly. This allows for precise fire extinguishing based on the actual conditions at the fire scene, timely control of the fire spread, and effectively improved fire extinguishing efficiency.
[0038] The scheme is further optimized. The translation component includes a lead screw motor 4 mounted on the bracket 3. The lead screw motor 4 is electrically connected to the control system. The output shaft of the lead screw motor 4 is equipped with a lead screw 5 through a coupling. A sliding sleeve 6 is slidably sleeved on the lead screw 5. The lead screw 5 is arranged laterally. The two sliding sleeves 6 are respectively fixedly connected to the two extended spray arm assemblies. The two lead screw motors 4 are symmetrically mounted on the bracket 3.
[0039] When the lead screw motor 4 starts, it drives the lead screw 5 to rotate through the coupling. The rotation of the lead screw 5 is converted into the linear motion of the sliding sleeve 6. The two sliding sleeves 6 can drive the corresponding extended sprinkler arm assemblies to slide along the central sleeve. By controlling the rotation direction and number of turns of the lead screw motor 4 through the control system, the moving distance and position of the extended sprinkler arm assemblies can be precisely controlled, thereby realizing the flexible adjustment of the single or double extended sprinkler arm assemblies to adapt to different fire extinguishing needs and expand the spray range.
[0040] Further optimization of the scheme: the extended spray arm assembly includes an extension tube 7 connected to the central sleeve. The two extension tubes 7 are slidably sleeved on both sides of the outer wall of the central sleeve. A plug 8 is fixedly installed at the end of the extension tube 7 away from the central sleeve. Several first nozzles 9 are installed on the outer wall of the extension tube 7. The outer walls of the two extension tubes 7 are fixedly connected to the two sliding sleeves 6 respectively.
[0041] The plug 8 serves as a seal to prevent leakage of the extinguishing liquid. Several first nozzles 9 are installed on the outer wall of the extension pipe 7. When the pumping assembly delivers the extinguishing liquid to the central sleeve, the extinguishing liquid enters the extension pipe 7 and is sprayed out through the first nozzles 9. Since the extension pipe 7 is fixedly connected to the sliding sleeve 6, when the translation assembly moves the sliding sleeve 6, the extension pipe 7 will also move accordingly, thereby adjusting the spray position of the first nozzles 9 to achieve fire extinguishing coverage of different areas.
[0042] Further optimization of the scheme: the bottom spray arm assembly includes a fixed spray pipe 10, which is fixedly installed at the bottom of the bracket 3. Several second nozzles 11 are installed on the fixed spray pipe 10. The fixed spray pipe 10 is connected to the pump assembly. The second nozzles 11 are arranged at an angle downward.
[0043] When the pump assembly is started, the extinguishing liquid is drawn from the storage tank 2 and delivered to the fixed spray pipe 10. After entering the fixed spray pipe 10, the extinguishing liquid is sprayed out through several second nozzles 11 installed on the fixed spray pipe 10 to spray the area below the extinguishing device in a comprehensive and uniform manner, and quickly control the spread of the fire source below the device.
[0044] The scheme is further optimized. The pump assembly includes a drain pipe 12, on which a booster pump and a solenoid valve 13 are installed. Both the booster pump and the solenoid valve 13 are electrically connected to the control system. The top of the drain pipe 12 is fixedly connected to and connected to the storage tank 2. The bottom of the drain pipe 12 is connected to two branch pipes through a three-way connector. The central sleeve and the fixed spray pipe 10 are fixedly connected to and connected to the two branch pipes respectively.
[0045] The control system opens the solenoid valve 13, which in turn starts the pressurizing pump. The pressurizing pump pressurizes the extinguishing liquid flowing from the storage tank into the drain pipe, giving the extinguishing liquid a certain pressure so that it can be smoothly delivered through the drain pipe 12 and branch pipe to the central sleeve and fixed sprinkler pipe 10, providing sufficient spraying power for the sprinkler arm assembly. By controlling the output power of the pressurizing pump and the opening of the solenoid valve, the control system can precisely adjust the pressure and flow rate of the extinguishing liquid, thereby controlling the spraying intensity and range of the sprinkler arm assembly.
[0046] The scheme is further optimized. The electric walking wheel assembly includes four walking motors. The four walking motors are respectively installed at the four corners of the bottom surface of the frame structure 1. Walking wheels 14 are installed on the output shaft of the walking motors. The walking motors are electrically connected to the control system.
[0047] When the fire extinguishing device needs to be moved to the fire scene, the control system controls the four walking motors to start running, and their output shafts drive the walking wheels 14 to rotate. By controlling the rotation direction and speed of the four walking motors, the movement direction and speed of the fire extinguishing device can be controlled, so that it can move automatically and stably to the fire scene in the mine roadway according to the preset path or the real-time fire location information received.
[0048] To further optimize the design, a water level observation window 15 is installed on the outer wall of the liquid storage tank 2, and the water level observation window 15 is equipped with a scale.
[0049] To further optimize the design, a liquid filling port 16 is installed on the top of the liquid storage tank 2.
