TECHNICAL FIELD

[0001] The utility model belongs to but is not limited to fire fighting pipeline technical field, especially a medium -large -sized tunnel fire fighting pipeline early warning device. BACKGROUND

[0002] The tunnel has a fire fighting device, and a fire fighting box is arranged every 50 meters in the tunnel, and a fire fighting water inlet, a water hose and a fire fighting lance are arranged in the fire fighting box, so that fire extinguishing and emergency treatment can be performed at any time.

[0003] At present, the tunnel fire fighting pipeline operates as follows:

[0004] The tunnel on the expressway is built in a remote mountainous area and is unattended

[0005] A ground water storage tank is arranged in the fire fighting pump house, and according to long-term use, it is found that most of the water storage tanks have a leakage phenomenon and are not easy to be found, and when the water storage tank leaks, the water storage tank will be automatically replenished, which will cause waste

[0006] The fire fighting pipeline in the tunnel is too long, and a fire fighting box, a pipeline joint and a valve are arranged every 50 meters, and the joints of the pipeline often leak, which reduces the pressure of the pipeline, and the stable pressure pump in the fire fighting pump house is frequently started to maintain pressure, and when the reverse stop valve at the front end of the stable pressure pump in the pump house is damaged, the working frequency of the stable pressure pump is further increased, and the electricity cost is increased.

[0007] The fire fighting pipeline of the large tunnel is too long, and the pressure of the terminal pipeline is attenuated, and in special cases, the terminal pressure is insufficient, which will affect the normal rescue work and cause safety hazards.

[0008] In view of the above analysis, the existing technology has the technical problems to be solved urgently: the fire fighting pipeline in the tunnel is too long, the joints of the pipeline often leak, which reduces the pressure of the pipeline, and the stable pressure pump in the fire fighting pump house is frequently started to maintain pressure, the working frequency of the stable pressure pump is further increased, and the electricity cost is increased. The fire fighting pipeline of the large tunnel is too long, and the pressure of the terminal pipeline is attenuated, and in special cases, the terminal pressure is insufficient, which will affect the normal rescue work and cause safety hazards. UTILITY MODEL CONTENTS

[0009] In view of the problems in the prior art, the utility model provides a medium -large -sized tunnel fire fighting pipeline early warning device, which can solve the problems of hidden faults in the existing medium -large -sized tunnel fire fighting pipeline, waste of resources and safety risk of rescue work in the tunnel in special cases.

[0010] The utility model discloses a kind of medium-large tunnel fire-fighting pipeline early warning devices, including water storage tank water seepage monitoring equipment in fire pump house, tunnel fire-fighting pipeline water seepage pressure relief monitoring equipment, tunnel fire-fighting pipeline end pressure deficiency monitoring equipment;

[0011] Water seepage monitoring equipment in fire pump house installs a power-on counter on the outgoing line of power supply line of deep-well pump in pump house distribution box, monitors the frequent start-up frequency of deep-well pump to quickly determine whether water storage tank can maintain original water level of water storage tank, and records the number of start-up each time when pumping power-on, and notifies the mobile phone of technical personnel through 4G network, and each time power-on start-up applet is recorded.

[0012] Tunnel fire-fighting pipeline water seepage pressure relief monitoring equipment installs a counting display on the power supply outgoing line of pressure stabilizing pump, records the start-up frequency of pressure stabilizing pump each time, and notifies the mobile phone of worker through 4G each time pressure stabilizing pump works, and is recorded in the mobile phone applet of worker.

[0013] Tunnel fire-fighting pipeline end pressure deficiency monitoring equipment installs a pressure gauge on the valve pipe of the front end of fire hose in the fire box of tunnel pipe end, sets pressure lower limit value, and when pressure is lower than set value, the normally open contact of pressure gauge is closed, and sound and light alarm is connected locally, and the mobile phone of worker is notified through 4G.

[0014] Further, water seepage monitoring equipment in fire pump house specifically includes: when water level of fire water storage tank is lower limit value, water level sensor normally open contact is closed, KM1 coil is powered, KM1 contactor is attracted, and fire pool water replenishment pump D1 works;

[0015] KA1 normally closed contact closes 4G, and remote mobile phone monitoring equipment works normally.

[0016] When fire pool water replenishment D1 works, KM1 is attracted, C point is powered, and counter is counted once per power-on;

[0017] When C point is powered, KA1 relay works, KA1 normally closed contact opens, 4G is cut off, and 4G loses power and notifies the mobile phone of worker to start alarm.

[0018] Further, tunnel fire-fighting pipeline water seepage pressure relief monitoring equipment specifically includes: when pipe pressure gauge is normal, KM2 is not powered, and pipe pressure stabilizing pump does not work, when pipe pressure gauge is too low, pipe pressure gauge normally closed contact is closed, and KM2 is powered.D2 pipe fire-fighting pipeline pressure stabilizing pump works to start pressure stabilization;

[0019] B point is powered through KA2 normally closed contact 4G transmission is normal;

[0020] When KM2 is powered, C point is powered, and the counter starts counting once; C point is powered, and KA2 synchronous is powered at the same time, which causes the upper KA2 normally closed contact to open, 4G transmission to lose power, and the staff's mobile phone and the management platform to be notified.

[0021] Further, the tunnel fire-fighting pipeline end pressure deficiency monitoring device specifically comprises: a normally closed contact of a KA3 relay controls 4G transmission, when the pipeline end pressure is insufficient, the normally open contact of the pressure gauge is closed, causing the KA3 electromechanical device to work; thus, the normally closed contact in front of 4G is disconnected, 4G loses power, and the staff's mobile phone and the platform are notified; when the pressure value of the pressure gauge is too low, the normally open contact of the pressure gauge is closed, and the normally open contact of the KA3 is closed, causing the local sound and light alarm to work.

[0022] In combination with the technical solutions and the solved technical problems described above, the technical solutions to be protected by the utility model have the following advantages and positive effects:

[0023] The staff can check the installation counter number of the fire pump house to judge the water storage condition of the water storage pool and the pressure maintaining condition of the main pipeline. The staff can also know whether the pressure in the whole pipeline is normal by listening to the alarm sound at the end of the main pipeline. The staff can also master the water leakage of the water storage pool and the fire-fighting pipeline and the pipeline end pressure deficiency problem in the tunnel in real time through the 4G network of the staff's mobile phone, which ensures the safety of tunnel fire-fighting and reduces unnecessary waste.

[0027] In order to make the purpose, technical solutions and advantages of the utility model more clear and explicit, the utility model is further described in detail below in combination with embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and do not limit the utility model.

[0028] A medium-large tunnel fire-fighting pipeline early warning device, comprising monitoring water leakage of a water storage pool in a fire pump house, water leakage pressure relief of a tunnel fire-fighting pipeline, and end pressure deficiency of a tunnel fire-fighting pipeline.

[0029] The water storage tank in the fire pump room seeps water, causing the deep well pump to work continuously to pump water to the storage tank. A power-on counter is installed on the outlet of the power supply line of the deep well pump in the pump room distribution box, so that the number of frequent start-ups of the deep well pump can be monitored to quickly determine whether the storage tank can maintain the original water level of the storage tank. Each time the pump is powered on, the number of start-ups is recorded, and the technician's mobile phone is notified through the 4G network. Each power-on subprogram is recorded. The staff can keep abreast of the tunnel fire pool water storage situation.

[0030] The main pipe of the tunnel fire is too long, and the joints are too many. If the joints leak, the pipe leaks, the tunnel fire pump room pressure stabilizing pump works frequently. A recording display is installed on the power supply outlet of the pressure stabilizing pump to record the number of start-ups of the pressure stabilizing pump each time, and the staff's mobile phone is notified through 4G each time the pressure stabilizing pump works, and the staff's mobile phone subprogram is recorded.

[0031] The tunnel pipe is too long, and the end of the pipe has low pressure decay. A pressure gauge is installed on the valve pipe at the front end of the fire hose in the fire box at the end of the tunnel pipe. The pressure limit value is set by yourself. When the pressure is lower than the set value, the normally open contact of the pressure gauge closes, and the sound and light alarm is connected locally. At the same time, the staff's mobile phone is notified through 4G, so that the staff can quickly master the insufficient pressure at the end of the tunnel pipe.

[0032] The staff can check the numbers of the installed counters in the fire pump room during routine inspection to determine the water storage situation of the storage tank and the pressure maintaining situation of the main pipe. The staff can also check the pressure situation of the entire pipe by listening to the alarm sound at the end of the main pipe. The staff can also master the problems of water leakage in the tunnel storage tank and fire pipe and insufficient pressure at the end of the pipe through their own mobile phone 4G network in different places. This ensures the safety of tunnel fire protection and reduces unnecessary waste.

[0033] As shown in Figure 1 When the water level of the fire storage tank reaches the lower limit, the normally open contact of the water level sensor closes, the KM1 coil is powered on, the KM1 contactor is attracted, and the fire tank water replenishment pump D1 works.

[0034] The KA1 normally closed contact closes 4G, and the remote mobile phone monitoring equipment works normally.

[0035] When the fire tank water replenishment D1 works, KM1 is attracted, C point has power, and the counter counts once every time it is powered on.

[0036] When C point has power, KA1 relay works, KA1 normally closed contact opens, cuts off 4G, and 4G loses power to notify the staff's mobile phone to start alarm.

[0037] As shown in Figure 2As shown, when the pipeline pressure gauge is normal, KM2 is not powered, and the pipeline pressure stabilizing pump does not work. When the pipeline pressure gauge reading is too low, the normally closed contact of the pipeline pressure gauge closes, and KM2 is powered on. The D2 pipeline fire pipeline pressure stabilizing pump then starts to stabilize the pressure.

[0038] There is power at point B, and 4G transmission is normal through the normally closed contact KA2.

[0039] When KM2 is powered, point C is also powered, and the counter starts counting once. Simultaneously, KA2 is also powered, causing the normally closed contact of KA2 to open, de-energizing 4G transmission and notifying staff on their mobile phones and the management platform.

[0040] like Figure 3 As shown, the normally closed contact of the KA3 relay controls 4G transmission. When the pressure at the end of the pipeline is insufficient, the normally open contact of the pressure gauge closes, causing the KA3 electromechanical unit to operate. This causes the normally closed contact before the 4G relay to open, de-energizing the 4G network and notifying the operator's mobile phone and platform. If the pressure gauge reading is too low, the normally open contact of the pressure gauge closes, and the normally open contact of the KA3 relay closes, triggering the local audible and visual alarms.

[0041] Using the above technologies, when a fire water tank leaks and needs replenishment, when a fire pipeline leaks and needs depressurization, or when the pressure at the end of a fire pipeline is insufficient, the information can be transmitted to the staff's mobile phone via 4G. At the same time, during routine on-site inspections, staff can determine the fault by checking the number of times the water tank replenishment pump and pressure stabilizing pump operate, as well as the audible and visual alarms at the end of the pipeline.
