[0034] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0035] The following is for reference. Figures 1-5 This invention describes a coal yard fire prevention and extinguishing device 100 having a pipeline insulation component 90 according to an embodiment of the present invention.

[0036] Please see Figures 1-4 The coal yard fire prevention and extinguishing device 100 with pipeline insulation component 90 includes a mixing component 10, a shotcrete pump 20, a pipeline insulation component 90, a vehicle body 70, and a compartment 80. The mixing component 10, the shotcrete pump 20, and the compartment 80 are all mounted on the vehicle body 70, and the mixing component 10 and the shotcrete pump 20 are located inside the compartment 80.

[0037] The mixing assembly 10 includes a mixing chamber 11, within which a mixing cavity is defined. The mixing chamber 11 is provided with a water inlet 111, a material inlet 112, and a slurry outlet 113 communicating with the mixing cavity. A slurry outlet control valve 1131 is provided at the slurry outlet 113 for controlling the opening and closing of the slurry outlet 113. The water inlet 111 is adapted to connect to a water source to add water into the mixing cavity. It should be noted that the "water source" mentioned here can be arbitrarily selected according to actual needs. For example, the water source can be fire-fighting water for the fire prevention and extinguishing operation area. By using fire-fighting water for the fire prevention and extinguishing operation area as the water source, water can be directly obtained at the spraying site, which is convenient and efficient, and helps to improve the efficiency of fire prevention and extinguishing spraying operations. Of course, this application is not limited to this; the water source can also be filtered flushing water, etc.

[0038] Material inlet 112 is used to add materials into the mixing chamber, and the agitator is used to mix the materials for pulping. Slurry outlet 113 is used to discharge the pulp from the mixing chamber after pulping. Slurry outlet control valve 1131 is used to control the opening and closing of slurry outlet 113. During material addition and pulping, slurry outlet control valve 1131 is in the closed state; when slurrying is completed and spraying is performed, slurry outlet control valve 1131 can be opened so that the slurry in the mixing chamber can be discharged through slurry outlet 113.

[0039] The material inlet 112 may include only one or multiple inlets. For example, when the slurry required for spraying is a multi-component slurry, such as when the slurry components include component A and component B, the material inlet 112 may include component A inlet 1121 for adding component A and component B inlet 1122 for adding component B. Component A and component B can be arbitrarily selected according to actual needs. For example, component A may be powdered fly ash, and component B may be a powdered flame-retardant chemical composite material (powdered material). In some other embodiments, component A may also be a powdered material such as stone powder or bentonite, and component B may also be a liquid flame-retardant material (liquidized material).

[0040] The shotcrete pump 20 has a shotcrete inlet 21 and a shotcrete outlet 22. The shotcrete inlet 21 is connected to a slurry control valve 1131, meaning that the shotcrete inlet 21 is connected to a slurry outlet 113 via the slurry control valve 1131. Thus, when the slurry control valve 1131 is open, the slurry in the mixing chamber can sequentially enter the shotcrete pump 20 through the slurry outlet 113 and the shotcrete inlet 21. The shotcrete outlet 22 is suitable for connecting to a spray gun (not shown) or a grouting pipe (not shown). That is, the shotcrete outlet 22 can be connected to either a spray gun or a grouting pipe. When the shotcrete outlet 22 is connected to a spray gun, the slurry pumped from the shotcrete outlet 22 can be sprayed onto the surface of the fire-fighting area (e.g., a coal pile) through the spray gun; when the shotcrete outlet 22 is connected to a grouting pipe, the slurry pumped from the shotcrete outlet 22 can be injected into the fire-fighting area (e.g., a coal pile) through the grouting pipe.

[0041] By setting up a vehicle body 70 and installing both the mixing component 10 and the shotcrete pump 20 on the vehicle body 70, the coal yard fire prevention and extinguishing device 100 can move freely during the slurry preparation and shotcrete processes, making it flexible and convenient to use. This not only improves work efficiency but also greatly shortens the shotcrete pipeline, thereby saving costs.

[0042] In addition, by setting up the chamber 80 and placing the mixing component 10 and the shotcrete pump 20 inside the chamber 80, the mixing component 10 and the shotcrete pump 20 can be protected and kept warm.

[0043] Of course, this application is not limited to this. In some other embodiments, the coal yard fire prevention and extinguishing device 100 may not include the aforementioned compartment 80.

[0044] In some other embodiments, the coal yard fire prevention and extinguishing device 100 may not include the aforementioned motor vehicle body 70.

[0045] Understandably, the inlet 111 and the water source, the slurry control valve 1131 and the slurry inlet 21, and the slurry outlet 22 and the spray gun, or the slurry outlet 22 and the grouting pipe, all need to be connected by connecting pipes 30. Among them, the connecting pipe 30 between the inlet 111 and the water source is the water flow transmission pipe 31, the connecting pipe 30 between the slurry inlet 21 and the slurry control valve 1131 is the slurry outlet pipe 32, and the connecting pipe 30 between the slurry outlet 22 and the spray gun, or the slurry outlet 22 and the grouting pipe, is the slurry transmission pipe 33.

[0046] When the coal yard fire prevention and extinguishing device 100 is used in colder regions, the aforementioned connecting pipes 30 often freeze, causing the coal yard fire prevention and extinguishing device 100 to malfunction and thus affecting the efficiency of fire prevention and extinguishing work.

[0047] To address the aforementioned technical issues, the coal yard fire prevention and extinguishing device 100 of this application further includes a pipeline insulation component 90, which is used to insulate the connecting pipeline 30. The pipeline insulation component 90 is used to wrap the connecting pipeline 30 (water flow transmission pipe 31) between the water inlet 111 and the water source, the connecting pipeline 30 (slurry outlet pipe 32) between the slurry inlet 21 and the slurry outlet control valve 1131, and the connecting pipeline 30 (slurry transmission pipe 33) between the slurry outlet 22 and the spray gun or grouting pipe. In other words, the connecting pipe 30 (water flow transmission pipe 31) between the water inlet 111 and the water source is wrapped with a pipe insulation component 90, the connecting pipe 30 (slurry outlet pipe 32) between the grouting inlet 21 and the slurry outlet control valve 1131 is wrapped with a pipe insulation component 90, and the connecting pipe 30 (slurry transmission pipe 33) between the grouting outlet 22 and the spray gun or between the grouting outlet 22 and the grouting pipe is also wrapped with a pipe insulation component 90.

[0048] According to an embodiment of the present invention, a coal yard fire prevention and extinguishing device 100 with a pipeline insulation component 90 can prevent freezing inside the connecting pipeline 30 by wrapping the connecting pipeline 30 with the pipeline insulation component 90, thereby ensuring the normal operation of the equipment.

[0049] In one embodiment of this utility model, please refer to Figures 4-5 The pipeline insulation component 90 includes a thermal insulation layer 901, which wraps around the connecting pipeline 30. It should be noted that the "thermal insulation layer 901" mentioned here is made of thermal insulation material, which makes the thermal insulation layer 901 provide better insulation for the connecting pipeline 30.

[0050] Optionally, the thermal insulation layer 901 can be made of rubber, silicone, or foam. That is, the thermal insulation layer 901 can be made of rubber, silicone, or foam materials. By making the thermal insulation layer 901 a rubber, silicone, or foam component, not only is the thermal insulation effect of the thermal insulation layer 901 better, but it also has higher structural strength and better stability, thus giving the thermal insulation layer 901 a longer service life.

[0051] Of course, this application is not limited to this, and the thermal insulation layer 901 can also be an asbestos component, a glass wool component, a ceramic fiber component, or a glass fiber component, etc.

[0052] For further information, please refer to [link / reference]. Figure 5 The pipe insulation assembly 90 also includes an electric heating element 902, which is disposed between the thermal insulation layer 901 and the connecting pipe 30. By placing the electric heating element 902 between the thermal insulation layer 901 and the connecting pipe 30, the electric heating element 902 can be energized to generate heat and heat the connecting pipe 30. In this way, the pipe insulation assembly 90 not only provides insulation for the connecting pipe 30 but also provides heating, thereby better preventing freezing inside the connecting pipe 30.

[0053] Alternatively, please continue reading Figure 5 The electric heating element 902 is wound around the outer peripheral wall of the connecting pipe 30. This increases the contact area between the electric heating element 902 and the connecting pipe 30, resulting in better heating of the connecting pipe 30 by the electric heating element 902. In addition, by winding the electric heating element 902 around the outer peripheral wall of the connecting pipe 30, the installation and positioning of the electric heating element 902 can be facilitated.

[0054] Optionally, the electric heating element 902 is an electric heat tracing device, which has high heating efficiency, saves energy, and is safe and reliable in use. Of course, this application is not limited to this, and the electric heating element 902 can also be an electric heating wire, etc.

[0055] In one embodiment of this utility model, please refer to Figures 4-5 The pipeline insulation component 90 also includes a protective layer 903, which wraps around the thermal insulation layer 901. The protective layer 903 can protect the thermal insulation layer 901, thereby preventing damage and aging of the thermal insulation layer 901 and extending its service life.

[0056] Optionally, the protective layer 903 is an aluminum foil layer or a corrosion-resistant asphalt fiberglass layer. That is, the protective layer 903 can be made of aluminum foil or corrosion-resistant asphalt fiberglass. By making the protective layer 903 an aluminum foil layer or a corrosion-resistant asphalt fiberglass layer, the protective effect of the protective layer 903 can be improved, and it is lightweight and low-cost. Optionally, the protective layer 903 can be fixed to the outside of the thermal insulation layer 901 by adhesive bonding. For example, the protective layer 903 can be formed by bonding aluminum foil tape to the outside of the thermal insulation layer 901, thereby ensuring high stability of the connection between the protective layer 903 and the thermal insulation layer 901, and simplifying the connection method.

[0057] In one embodiment of this utility model, please refer to Figures 2-3 The mixing chamber 11 is provided with an overflow port 114 communicating with the mixing chamber. The overflow port 114 is connected to the shotcrete outlet 22. The connecting pipe 30 between the overflow port 114 and the shotcrete outlet 22 is wrapped with a pipe insulation component 90. The connecting pipe 30 between the overflow port 114 and the shotcrete outlet 22 is an overflow pipe 34. One end of the overflow pipe 34 is connected to the shotcrete outlet 22, and the other end of the overflow pipe 34 is connected to the overflow port 114.

[0058] Please continue reading. Figures 2-3 The coal yard fire prevention and extinguishing device 100 also includes a pressure relief valve 341 and a pressure detection device (not shown in the figure). The pressure relief valve 341 is connected to the other end of the overflow pipe 34 and the overflow port 114. That is, the slurry outlet 22 and the overflow port 114 are connected through the overflow pipe 34, and the pressure relief valve 341 is located between the overflow port 114 and the overflow pipe 34 to control the opening and closing of the overflow port 114 and the overflow pipe 34. The pressure detection device is used to detect the pressure at the slurry outlet 22. The pressure detection device is electrically connected to the pressure relief valve 341 to control the opening and closing of the pressure relief valve 341 according to the pressure value detected by the pressure detection device. Specifically, when the pressure value detected by the pressure detection device is greater than the set pressure value, the pressure relief valve 341 opens, thereby allowing the slurry outlet 22 to communicate with the mixing chamber through the overflow pipe 34, and transporting the slurry at the slurry outlet 22 back into the mixing chamber, thereby realizing pipeline pressure relief. In case of pipeline blockage, timely pressure relief can avoid the risk of pipe bursting.

[0059] By wrapping the connecting pipe 30 (overflow pipe 34) between the overflow port 114 and the grout outlet 22 with a pipe insulation component 90, the connecting pipe 30 (overflow pipe 34) between the overflow port 114 and the grout outlet 22 can be insulated to prevent the grout in this part of the connecting pipe 30 (overflow pipe 34) from freezing.

[0060] Further, please refer to Figures 2-3The coal yard fire prevention and extinguishing device 100 also includes a first connecting joint 40 and a second connecting joint 50. The first connecting joint 40 includes a first connecting port 41, a second connecting port 42, and a third connecting port 43 that are interconnected. The first connecting port 41 is connected to the slurry outlet 22, and the second connecting port 42 is connected to the pressure detection device. The second connecting joint 50 includes a fourth connecting port 51, a fifth connecting port 52, and a sixth connecting port 53 that are interconnected. The fourth connecting port 51 is connected to the third connecting port 43, the fifth connecting port 52 is connected to the slurry transmission pipe 33, and the sixth connecting port 53 is connected to the overflow pipe 34. Both the first connecting joint 40 and the second connecting joint 50 can be tee pipes. By setting the first connecting joint 40 and the second connecting joint 50, connections can be made between the slurry outlet 22 and the slurry transmission pipe 33, between the slurry outlet 22 and the overflow pipe 34, and between the slurry outlet 22 and the pressure detection device. The connection structure is simple, the internal connection structure of the equipment is neat and orderly, and maintenance is convenient.

[0061] Understandably, due to the viscous and easily solidified properties of the slurry, the equipment is usually flushed promptly after spraying to prevent residual slurry from solidifying and clogging the pipes. In the prior art, flushing water is added through the inlet 111 of the mixing chamber 11 during flushing. This method is insufficient to thoroughly flush the residual slurry in the connecting pipe 30 (slurry outlet pipe 32) between the slurry outlet control valve 1131 and the spraying inlet 21, resulting in a high frequency of clogging in this connecting pipe 30 (slurry outlet pipe 32).

[0062] To address the aforementioned issues, in one embodiment of this application, please refer to... Figures 2-3 A backwashing port 63 is provided between the slurry outlet pipe 32 and the slurry inlet 21, communicating with both the slurry outlet pipe 32 and the slurry inlet 21. That is, a backwashing port 63 is provided between the slurry outlet pipe 32 and the slurry inlet 21, and the backwashing port 63 is connected to both the slurry outlet pipe 32 and the slurry inlet 21. The backwashing port 63 is suitable for connecting to a water source, so that flushing water can be delivered from the downstream side of the slurry outlet pipe 32 into the mixing chamber through the backwashing port 63. This reverse delivery of flushing water allows residual slurry in the connecting pipe 30 (slurry outlet pipe 32) between the slurry control valve 1131 and the slurry inlet 21 to be flushed more cleanly and thoroughly, greatly reducing the occurrence of blockage in this part of the connecting pipe 30 (slurry outlet pipe 32).

[0063] Furthermore, the connecting pipe 30 between the backwash interface 63 and the water source is also wrapped with a pipe insulation component 90. The connecting pipe 30 between the backwash interface 63 and the water source is a backwash water transmission pipe 35. By wrapping the backwash water transmission pipe 35 with the pipe insulation component 90, the backwash water transmission pipe 35 can be insulated to prevent freezing inside the backwash water transmission pipe 35.

[0064] Further, please refer to Figures 2-3 A third connecting joint 60 is provided between the slurry outlet pipe 32 and the shotcrete inlet 21. The third connecting joint 60 includes a seventh connecting port 61, an eighth connecting port 62, and a ninth connecting port 63 that are interconnected. The seventh connecting port 61 is connected to the slurry outlet pipe 32, the eighth connecting port 62 is connected to the shotcrete inlet 21, and the ninth connecting port 63 forms a backwash interface 63, which is connected to the backwash water transmission pipe 35. By setting the third connecting joint 60, the connection between the slurry outlet pipe 32, the shotcrete pump 20, and the backwash water transmission pipe 35 becomes simpler and more convenient.
