TECHNICAL FIELD

[0001] The utility model relates to fire prevention and extinguishing technical field especially to a coal yard fire prevention and extinguishing device with emergency water tank. BACKGROUND

[0002] Nowadays, in the power plant, steel plant, port and other places where coal is stacked, the coal is easy to self-ignite due to oxidation, causing adverse effects such as heat value reduction, environmental pollution, fire, etc. In order to solve this problem, a gunite equipment is generally used to form an oxygen barrier on the surface of the coal stack to block the air leakage and oxygen supply channel, slowing down the oxidation process of the coal body, thereby playing a role in preventing and extinguishing the coal stack.

[0003] Understandably, water is needed in the process of gunite. In the related art, a relatively long water pipe is generally used to connect the water source and the gunite equipment to supply water to the gunite equipment.

DETAILED DESCRIPTION

[0022] Embodiments of the present application will be described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numbers represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation of the present application.

[0023] Reference will be made to Figures 1-2 A coal yard fire prevention and extinguishing device 100 with an emergency water tank according to an embodiment of the present application is described below.

[0024] Reference is made to Figures 1-2 As shown in the figure, the coal yard fire prevention and extinguishing device 100 comprises a fire prevention and extinguishing part 10 and a motor vehicle body 20, and the fire prevention and extinguishing part 10 is arranged on the motor vehicle body 20.

[0025] The fire prevention and extinguishing part 10 can be used for slurry preparation and slurry injection. By arranging the fire prevention and extinguishing part 10 on the motor vehicle body 20, the coal yard fire prevention and extinguishing device 100 can be freely moved during the addition of materials, slurry preparation and slurry injection. For example, when the coal yard fire prevention and extinguishing device 100 needs to add fly ash, the coal yard fire prevention and extinguishing device 100 can be opened to the ash bin to receive ash, and then the coal yard fire prevention and extinguishing device 100 can be opened to the slurry injection site for slurry preparation and slurry injection. Therefore, the coal yard fire prevention and extinguishing device 100 is very flexible and convenient during use, thereby improving work efficiency, and at the same time, the slurry injection pipeline can be greatly shortened, thereby saving costs.

[0026] Optionally, reference is made to Figures 1-2The coal yard fire extinguishing device 100 further comprises a compartment 30, at least a part of the fire extinguishing part 10 is accommodated in the compartment 30. By arranging the compartment 30, the fire extinguishing part 10 can be protected.

[0027] Optionally, referring to Figure 1 The side wall of the compartment 30 can be further provided with a heat dissipation window, and a heat dissipation fan is arranged in the heat dissipation window. The heat dissipation fan drives the air exchange between the inside and outside of the compartment 30, thereby reducing the temperature inside the compartment 30.

[0028] Optionally, referring to Figure 1 The compartment 30 can be provided with a plurality of operation windows 301, and each operation window 301 is provided with a door body 3011 for opening or closing the operation window 301. In this way, when it is necessary to overhaul or operate the valve and other components of the fire extinguishing part, the corresponding door body 3011 of the operation window 301 can be opened for operation. Or when it is necessary to dissipate heat for the fire extinguishing part 10 located in the compartment 30, the door body 3011 can be opened to speed up the heat dissipation efficiency.

[0029] The size of the door body 3011 can be arbitrarily selected as required. In some embodiments, when the door body 3011 is opened, the side wall surface of the compartment 30 is fully opened, which is helpful for heat dissipation and is suitable for use in hot areas. When the door body 3011 is opened, the heat dissipation is faster. In some embodiments, when the door body 3011 is opened, only a part of the side wall surface of the compartment 30 is opened, which is suitable for use in cold areas and can ensure the heat preservation effect of the compartment 30.

[0030] The opening mode of the door body 3011 can be arbitrarily selected as required. For example, the door body 3011 can be a flat door, a flip door (upward flip door or downward flip door), or a folding door. In addition, the door body 3011 can also be an automatic door, such as a hydraulic door or an electric door, so that manual control of the opening and closing of the door body 3011 is not required, and the operation is more labor-saving, and the coal yard fire extinguishing device 100 is more intelligent as a whole. Of course, the present application is not limited to this, and the door body 3011 can also be a manual door, which is beneficial to reduce the cost. Alternatively, a part of the door bodies 3011 of the coal yard fire extinguishing device 100 are automatic doors, and the other door bodies 3011 are manual doors. In this way, when the automatic door fails to drive and causes the door body to be unable to be normally opened, the manual door can be manually opened, thereby ensuring that the fire extinguishing work of the coal yard fire extinguishing device 100 is not affected.

[0031] The fire prevention and extinguishing part 10 comprises a mixing and stirring assembly, a mortar pump 12, an emergency water tank 13 and a stirring water supply assembly. The mixing and stirring assembly comprises a stirring bin 11, which defines a stirring cavity. The stirring bin 11 is provided with a water inlet 111, a material inlet 112 and a mortar outlet 113, which are in communication with the stirring cavity. The mortar outlet 113 is provided with a mortar control valve 1131 for controlling the opening and closing of the mortar outlet 113.

[0032] The water inlet 111 is used for adding water into the stirring cavity, the material inlet 112 is used for adding material into the stirring cavity, the stirring member is used for stirring the material to prepare mortar, and the mortar outlet 113 is used for discharging the prepared mortar in the stirring cavity. The mortar control valve 1131 is used for controlling the opening and closing of the mortar outlet 113. During the addition of material and the preparation of mortar, the mortar control valve 1131 is in a closed state. When the preparation of mortar is completed and mortar spraying is performed, the mortar control valve 1131 can be controlled to be opened, so that the mortar in the stirring cavity can be discharged through the mortar outlet 113.

[0033] The mortar pump 12 has a mortar inlet 121 and a mortar outlet 122. The mortar inlet 121 is connected to the mortar control valve 1131, and the mortar outlet 122 is adapted to be connected to a spray gun or a grouting pipe. That is, the mortar inlet 121 is connected to the mortar outlet 113 through the mortar control valve 1131, so that when the mortar control valve 1131 is opened, the mortar in the stirring cavity can be transported to the mortar inlet 121 through the mortar outlet 113, and then the mortar can be pumped from the mortar inlet 121 to the mortar outlet 122 under the drive of the mortar pump 12, and then sprayed to the surface of the coal pile through the spray gun or injected into the coal pile through the grouting pipe.

[0034] The emergency water tank 13 has an emergency water inlet 131 and an emergency water outlet 132. The emergency water inlet 131 is adapted to be connected to a water source to add water into the emergency water tank 13 through the emergency water inlet 131. It should be noted that the "water source" described in the present application can be selected as needed. For example, the water source can be fire-fighting water in the fire prevention and extinguishing operation area. By making the water source be the fire-fighting water in the fire prevention and extinguishing operation area, water can be conveniently taken at the mortar spraying site. Of course, the present application is not limited thereto, and the water source can also be filtered washing water and the like.

[0035] The emergency water inlet 131 is connected to the water source pipe (for example, a fire-fighting water pipe), so that water is added and stored in the emergency water tank 13. After the emergency water tank 13 is filled with water, the connection between the emergency water inlet 131 and the water source pipe can be cut off.

[0036] The stirring water supply assembly is used for adding water required for pulping into the stirring cavity, and comprises a stirring water supply pipe 141 having a stirring water supply inlet end 1411 and a stirring water supply outlet end 1412, the stirring water supply inlet end 1411 is selectively communicated with one of a water source and the emergency water outlet 132, and the stirring water supply outlet end 1412 is communicated with the water inlet 111. That is, the stirring water supply inlet end 1411 can be communicated with the water source, or the stirring water supply inlet end 1411 can be communicated with the emergency water outlet 132, and the selection can be made at will according to actual needs during use.

[0037] When the stirring water supply inlet end 1411 is communicated with the water source, water at the water source is transported to the water inlet 111 of the stirring cavity through the stirring water supply pipe 141 and enters the stirring cavity through the water inlet 111. The stirring water supply inlet end 1411 is communicated with the water source by connecting the stirring water supply inlet end 1411 with a water source pipe (for example, a fire-fighting water pipe). After water is added into the stirring cavity, the connection between the water source pipe (for example, the fire-fighting water pipe) and the stirring water supply inlet end 1411 can be cut off. When the stirring water supply inlet end 1411 is communicated with the emergency water outlet 132, water stored in the emergency water tank 13 is transported to the water inlet 111 of the stirring cavity through the stirring water supply pipe 141 and enters the stirring cavity through the water inlet 111.

[0038] That is, when the stirring water supply inlet end 1411 is communicated with the water source, the stirring water supply assembly adds water required for pulping into the stirring cavity in a water source water supply mode; when the stirring water supply inlet end 1411 is communicated with the emergency water outlet 132, the stirring water supply assembly adds water required for pulping into the stirring cavity in an emergency water tank 13 water supply mode.

[0039] It can be understood that when the stirring water supply assembly adds water required for pulping into the stirring cavity in the water source water supply mode, the connection between the stirring water supply assembly and the water source needs to be ensured. That is, a long water pipe needs to be used to connect the water source and the stirring water supply assembly together, or the coal yard fire extinguishing device 100 needs to be moved to the vicinity of the water source; when the stirring water supply assembly adds water required for pulping into the stirring cavity in the emergency water tank 13 water supply mode, only a certain amount of water needs to be stored in the emergency water tank 13 in advance, and the coal yard fire extinguishing device 100 does not need to be moved and the water source does not need to be connected, so that the water supply demand of the stirring cavity can be met in the shortest time in an emergency.

[0040] The coal yard fire extinguishing device 100 with the emergency water tank 13 can supply water for the stirring bin 11 in an emergency, so that not only the water supply pipeline can be saved, but also the coal yard fire extinguishing device 100 can be prevented from moving back and forth between the water source and the pulping site, and the construction efficiency is improved.

[0041] In an embodiment of the present application, please refer to Figure 2 The stirring water supply pipe 141 comprises a first stirring water supply section 1413 and a second stirring water supply section 1414, and the stirring water supply assembly further comprises a flow metering device 142 and a stirring water inlet control valve 143. The flow metering device 142 is connected between the first stirring water supply section 1413 and the second stirring water supply section 1414, that is, the first stirring water supply section 1413 and the second stirring water supply section 1414 are connected through the flow metering device 142. One end of the first stirring water supply section 1413 away from the flow metering device 142 forms a stirring water supply inlet end 1411, and one end of the second stirring water supply section 1414 away from the flow metering device 142 forms a stirring water supply outlet end 1412. The flow metering device 142 is used for metering the water flow in the stirring water supply pipe 141, that is, the flow metering device 142 is used for metering the flow of water added into the stirring cavity through the stirring water supply assembly. Optionally, the flow metering device 142 is a flow meter. The stirring water inlet control valve 143 is arranged between the stirring water supply outlet end 1412 and the water inlet 111. The stirring water inlet control valve 143 is used for controlling the on-off between the stirring water supply outlet end 1412 and the water inlet 111. When the stirring water inlet control valve 143 is opened, the stirring water supply outlet end 1412 and the water inlet 111 are communicated, and water can be delivered into the stirring cavity through the stirring water supply pipe 141; when the stirring water inlet control valve 143 is closed, the stirring water supply outlet end 1412 and the water inlet 111 are disconnected, and the water supply into the stirring cavity is stopped.

[0042] The stirring water inlet control valve 143 is electrically connected with the flow metering device 142. The stirring water inlet control valve 143 and the flow metering device 142 can be electrically connected with the control device of the coal yard fire extinguishing device 100. The flow metering device 142 feeds back the detected water flow signal to the control device, and the control device controls the stirring water inlet control valve 143 to be closed according to the water flow signal fed back by the flow metering device 142. For example, when the water flow detected by the flow metering device 142 reaches the required water amount for pulping, the control device controls the stirring water inlet control valve 143 to be closed, and the water supply into the stirring cavity is stopped.

[0043] As can be seen from the above, by making the stirring water supply assembly further comprise the flow metering device 142 and the stirring water inlet control valve 143, and the flow metering device 142 and the stirring water inlet control valve 143 are electrically connected, the stirring water supply assembly can realize automatic quantitative water adding into the stirring cavity, which cannot be manually measured, thereby saving labor and improving water adding accuracy.

[0044] In an embodiment of the present application, please refer to Figure 2, the fire prevention and extinguishing part 10 further comprises a main water supply control valve 151, a main water supply pipe 152, a first connecting joint 16 and an emergency water outlet control valve 1321, the inlet end of the main water supply control valve 151 is adapted to be connected with a water source, the outlet end of the main water supply control valve 151 is connected with one end of the main water supply pipe 152, the first connecting joint 16 comprises a first connecting port 161, a second connecting port 162 and a third connecting port 163 which are in communication with each other, the first connecting port 161 is in communication with the other end of the main water supply pipe 152, the second connecting port 162 is in communication with the stirring water inlet end 1411, and the third connecting port 163 is in communication with the emergency water outlet 132. The emergency water outlet control valve 1321 is arranged at the emergency water outlet 132 for controlling the opening and closing of the emergency water outlet 132, and the third connecting port 163 is in communication with the emergency water outlet 132 through the emergency water outlet control valve 1321. The emergency water outlet control valve 1321 can be an electric control valve or a manual valve.

[0045] The water source is connected with the main water supply pipe 152 through the main water supply control valve 151, and the main water supply control valve 151 is used for controlling the on-off between the water source and the main water supply pipe 152. Optionally, the main water supply control valve 151 can be a manual ball valve, which is simple in structure, low in cost and convenient to operate. When the main water supply control valve 151 is opened, the water source is transported to the first connecting joint 16 through the main water supply pipe 152, and then enters the stirring water supply pipe 141 through the first connecting port 161 and the second connecting port 162 of the first connecting joint 16 in sequence, and is transported to the stirring cavity through the stirring water supply pipe 141, thereby realizing the water source water supply mode described above. When the main water supply control valve 151 is closed, the water source is not connected with the main water supply pipe 152, and at this time, the connection between the water source pipe and the main water supply control valve 151 can be removed, so that the coal yard fire prevention and extinguishing device 100 can freely move after water supply is completed. When emergency water supply is needed, the emergency water outlet control valve 1321 is opened, and the water in the emergency water tank 13 can be transported to the first connecting joint 16 through the emergency water outlet 132, and then enter the stirring water supply pipe 141 through the third connecting port 163 and the second connecting port 162 of the first connecting joint 16 in sequence, and is transported to the stirring cavity through the stirring water supply pipe 141, thereby realizing the emergency water tank 13 water supply mode described above.

[0046] Further, a liquid delivery pump (not shown in the figure) is arranged between the third connecting port 163 and the emergency water outlet control valve 1321, so as to pump the water flowing out of the emergency water outlet 132 towards the third connecting port 163, thereby ensuring that the water in the emergency water tank 13 can be quickly and smoothly transported to the stirring cavity. Optionally, the liquid delivery pump can be a water pump, a metering pump or a booster pump, etc.

[0047] Further, please refer to Figure 2The first connecting joint 16 further comprises a fourth connecting port 164 in communication with the first connecting port 161, the second connecting port 162 and the third connecting port 163. The fourth connecting port 164 is in communication with the emergency water injection port 131. The fire extinguishing part 10 further comprises an emergency water injection control valve 1311 arranged at the emergency water injection port 131 for controlling the opening and closing of the emergency water injection port 131. The emergency water injection port 131 and the fourth connecting port 164 are connected through the emergency water injection control valve 1311. When the emergency water injection control valve 1311 is opened, the emergency water injection port 131 and the fourth connecting port 164 are in communication. When the water source is delivered to the first connecting joint 16 through the main water supply pipe 152, the water can be delivered to the emergency water injection port 131 through the first connecting port 161 and the fourth connecting port 164 in sequence, and then enters the emergency water tank 13 through the emergency water injection port 131 and is stored in the emergency water tank 13, so as to realize the water storage of the emergency water tank 13. After the water storage of the emergency water tank 13 is completed, the emergency water injection control valve 1311 can be closed. Optionally, the emergency water injection control valve 1311 can be an electric control valve or a manual valve.

[0048] Further, the emergency water tank 13 is provided with a liquid level detection device for detecting the liquid level in the emergency water tank 13. Optionally, the liquid level detection device can be a liquid level sensor. The liquid level detection device and the emergency water injection control valve 1311 are electrically connected. The liquid level detection device and the emergency water injection control valve 1311 can be electrically connected with the control device of the coal yard fire extinguishing device 100. The liquid level detection device feeds back the detected liquid level signal to the control device, and the control device controls the opening and closing of the emergency water injection control valve 1311 according to the liquid level signal fed back by the liquid level detection device. For example, when the liquid level value detected by the liquid level detection device is less than the first liquid level threshold, it indicates that the emergency water tank 13 is in a "water shortage" state at this time, and the control device controls the emergency water injection control valve 1311 to be opened to store water in the emergency water tank 13. When the liquid level value detected by the liquid level detection device is greater than the second liquid level threshold, it indicates that the emergency water tank 13 has been filled with water at this time, and the control device controls the emergency water injection control valve 1311 to be closed.

[0049] Optionally, the fire extinguishing part 10 further comprises an alarm device electrically connected with the liquid level detection device. When the liquid level value detected by the liquid level detection device is less than the first liquid level threshold, the alarm device sends a first prompt signal. When the liquid level value detected by the liquid level detection device is greater than the second liquid level threshold, the alarm device sends a second prompt signal.

[0050] Further, please refer to Figure 2The connecting pipeline between the slurry injection inlet 121 and the slurry outlet control valve 1131 is provided with a flushing interface 101. The fire prevention and extinguishing part 10 further comprises a second connecting joint 17 and a flushing water supply assembly. The second connecting joint 17 comprises a fifth connecting port 171, a sixth connecting port 172 and a seventh connecting port 173 which are in communication with each other. The fifth connecting port 171 is in communication with the second connecting port 162. The sixth connecting port 172 is in communication with the stirring water supply inlet end 1411. The flushing water supply assembly comprises a flushing water supply pipe 181 and a flushing water supply control valve 182. The flushing water supply pipe 181 comprises a flushing water supply inlet end and a flushing water supply outlet end. The flushing water supply inlet end is in communication with the seventh connecting port 173. The flushing water supply outlet end is in communication with the flushing interface 101. The flushing water supply control valve 182 is arranged between the flushing water supply inlet end and the seventh connecting port 173.

[0051] It can be understood that the coal yard fire prevention and extinguishing device 100 needs to undergo multiple rounds of stirring and slurry preparation and slurry injection when performing fire prevention and extinguishing work. Due to the viscous and easily solidified properties of the slurry, the slurry outlet 113 of the stirring bin 11 and the connecting pipeline between the slurry outlet 113 and the slurry injection pump 12 are prone to blockage. In order to avoid this problem, the connecting pipeline between the stirring bin 11 and the slurry injection pump 12 and the stirring bin 11 need to be flushed in time at the end of slurry injection. The flushing water supply assembly is used to provide flushing water to the flushing interface 101. Through the above connection, the flushing water supply assembly can also realize the water source water supply mode and the emergency water tank 13 water supply mode.

[0052] Specifically, when the flushing water supply assembly adopts the water source water supply mode to supply water to the flushing interface 101, first, the water source is connected to the main water supply control valve 151, and then the main water supply control valve 151 is opened. The water source enters the flushing water supply pipe 181 in sequence through the main water supply pipe 152, the first connecting port 161 of the first connecting joint 16, the second connecting port 162 of the first connecting joint 16, the fifth connecting port 171 of the second connecting joint 17 and the seventh connecting port 173 of the second connecting joint 17, and then is transported to the flushing interface 101 through the flushing water supply pipe 181. It should be noted that when the flushing water supply assembly adopts the water source water supply mode to supply water to the flushing interface 101, the emergency water injection control valve 1311, the emergency water outlet control valve 1321 and the stirring water inlet control valve 143 are in the closed state. The main water supply control valve 151 and the flushing water supply control valve 182 are in the open state.

[0053] When the flushing water supply assembly adopts the emergency water tank 13 water supply mode to supply water to the flushing interface 101, the emergency water outlet control valve 1321 is opened, and the water in the emergency water tank 13 sequentially passes through the emergency water outlet 132, the third connecting port 163 of the first connecting joint 16, the second connecting port 162 of the first connecting joint 16, the fifth connecting port 171 of the second connecting joint 17, the seventh connecting port 173 of the second connecting joint 17 and the flushing water supply control valve 182 into the flushing water supply pipe 181, and then is transported to the flushing interface 101 through the flushing water supply pipe 181. It should be noted that when the flushing water supply assembly adopts the emergency water tank 13 water supply mode to supply water to the flushing interface 101, the main water supply control valve 151, the emergency water injection control valve 1311 and the stirring water inlet control valve 143 are all in the closed state, and the emergency water outlet control valve 1321 and the flushing water supply control valve 182 are both in the open state.
