Description

Technical Field

[0001] The utility model relates to the technical field of kitchen safety equipment, in particular to a station kitchen monitoring and alarm system. Background Art

[0002] With the rapid development of modern industry, natural gas, as a clean and efficient energy source, has been widely used in all walks of life. In particular, natural gas transmission stations, as important hubs for natural gas supply, play a vital role in ensuring energy security and stable supply. However, in these stations, the living needs of employees cannot be ignored. The safe operation of employee canteens, as important places to meet employees' daily dietary needs, is crucial.

[0003] In the employee canteen of a natural gas transmission station, the kitchen is the main area where natural gas is used and is also a place with high safety risks. At present, most canteen kitchens use household combustible gas detectors to monitor natural gas leaks. However, these household detectors often have problems such as low detection accuracy and high false alarm rate, and cannot meet the needs of industrial-level safety monitoring. More importantly, these detectors usually lack natural gas cut-off linkage and exhaust linkage functions. Once a natural gas leak occurs, the gas source cannot be cut off in time and the exhaust system cannot be started, which increases the risk of fire and explosion. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a station kitchen monitoring alarm system, aiming to solve at least one of the above technical problems.

[0005] The technical solution of the utility model to solve the above technical problems is as follows:

[0006] A station kitchen monitoring and alarm system comprises a combustible gas detector, a cut-off solenoid valve, an explosion-proof fan, an audible and visual alarm, a fire detector and an alarm control cabinet, wherein the combustible gas detector, the fire detector, the cut-off solenoid valve, the explosion-proof fan and the audible and visual alarm are all electrically connected to the alarm control cabinet, the combustible gas detector and the fire detector are both installed in the station kitchen, the cut-off solenoid valve is installed at the inlet end of the air intake line of the station kitchen, the air inlet of the explosion-proof fan is connected to the station kitchen, and the air outlet of the explosion-proof fan is connected to the outdoors of the station kitchen.

[0007] The beneficial effects of the utility model are as follows: through the combustible gas detector installed in the station kitchen, the system can detect the combustible gas concentration in the kitchen in real time. Once the concentration exceeds the concentration safety threshold, the alarm control cabinet will immediately start the sound and light alarm, send out sound and light signals, and remind personnel to take countermeasures in time, thereby avoiding the occurrence of fire or explosion accidents. At the same time, the system can automatically cut off the gas source. The cut-off solenoid valve installed at the inlet end of the kitchen air intake pipeline cuts off the gas source after receiving the instruction issued by the alarm control cabinet according to the combustible gas concentration exceeding the concentration safety threshold, preventing the combustible gas from continuing to flow into the kitchen, thereby effectively preventing the accident from expanding. In addition, the explosion-proof fan is started for exhaust. The explosion-proof fan can quickly discharge the combustible gas in the kitchen to the outdoors through the connection with the station kitchen, reducing the combustible gas concentration in the kitchen and further reducing the risk of accidents.

[0008] By installing fire detectors, fire hazards in the kitchen can be monitored in real time. When the fire detector detects signs of fire in the station kitchen, the alarm control cabinet will immediately activate the sound and light alarm and send out sound and light signals. At the same time, the solenoid valve will cut off the gas source after receiving the command issued by the alarm control cabinet based on the signs of fire in the station kitchen, thereby improving the safety of the station kitchen.

[0009] On the basis of the above technical solution, the present invention can also be improved as follows.

[0010] Furthermore, the combustible gas detector is an infrared combustible gas detector, and the fire detector is a temperature-sensitive detector.

[0011] The beneficial effect of adopting the above further solution is that the infrared combustible gas detector can adapt to harsh environmental conditions, and its detection speed is faster and more robust. This enables it to work stably and reliably in environments such as station kitchens where there may be multiple interference factors.

[0012] The temperature detector can detect temperature changes around the fire source, has a fast and sensitive response speed, and can detect fire hazards in a timely manner. When the temperature detector detects that the temperature in the station kitchen exceeds the temperature safety threshold, the alarm controller activates the sound and light alarm to remind on-site personnel to take timely measures for rescue, thereby avoiding the occurrence of fire accidents.

[0013] Furthermore, the sound and light alarm is arranged on the top of the alarm control cabinet.

[0014] The beneficial effect of adopting the above further scheme is that the sound and light alarm is located at the top of the control cabinet, which is relatively high and can better attract people's attention. Once the concentration of combustible gas is detected to exceed the safety threshold, the sound and light alarm will emit a loud sound and obvious flash, so that the on-site personnel can quickly detect and respond, and take necessary safety measures in time. The sound and light alarm is set at the top of the control cabinet, which can keep it away from other equipment or obstacles on the ground, reducing false alarms caused by external interference. At the same time, the high-position setting also helps to avoid the accidental triggering of the alarm by personnel activities, and improves the stability and reliability of the system.

[0015] Further, it also includes an indoor explosion-proof operating column, the indoor explosion-proof operating column is connected to the explosion-proof fan, the indoor explosion-proof operating column is provided with a first start button and a first stop button, and the indoor explosion-proof operating column is installed in the station kitchen;

[0016] The indoor explosion-proof operating column is used to control the start and stop of the explosion-proof fan.

[0017] The beneficial effect of adopting the above further scheme is that the first start button and the first stop button set on the indoor explosion-proof operating column enable the staff to conveniently and directly control the operation of the explosion-proof fan inside the kitchen. This close-range operation method not only improves the convenience of operation, but also helps the staff to adjust the operating status of the fan in time according to actual conditions. Directly controlling the explosion-proof fan through the indoor explosion-proof operating column reduces the intermediate links of signal transmission, thereby speeding up the response speed of the system.

[0018] Further, it also includes an outdoor explosion-proof operation column, which is connected to the explosion-proof fan, and is provided with a second start button and a second stop button, and is installed outside the station kitchen;

[0019] The outdoor explosion-proof operating column is used to control the start and stop of the explosion-proof fan.

[0020] The beneficial effect of adopting the above further solution is that the provision of an outdoor explosion-proof operating column enables the staff to control the explosion-proof fan not only inside the kitchen, but also outside the kitchen. This flexible operation mode allows the staff to select the most convenient and safest position to control the operation of the explosion-proof fan according to actual needs, thereby improving work efficiency.

[0021] In emergency situations, such as fire accidents, the convenient operability and rapid response capabilities of the outdoor explosion-proof operating column can enable staff to take quick measures to control the operation of the explosion-proof fan, thereby effectively controlling the development of the accident and reducing losses.

[0022] Furthermore, the explosion-proof fan is an explosion-proof axial flow fan, and the explosion-proof fan is installed on the wall of the station kitchen.

[0023] The beneficial effect of adopting the above further solution is that the high air volume characteristic of the axial flow fan helps to quickly remove the fumes and harmful gases in the kitchen.

[0024] Furthermore, the explosion-proof blower includes an outer cylinder, a fan is provided inside the outer cylinder, a motor is connected to one side of the fan, and interception components are installed at both ends of the outer cylinder, and the interception components are used to prevent impurities from entering the inner part of the outer cylinder.

[0025] The beneficial effect of adopting the above further solution is that the protection capability of the fan is further enhanced by the interception component. The interception component can effectively block impurities and prevent them from entering the inner part of the outer cylinder and causing damage to the fan and the motor.

[0026] Furthermore, the interception component includes a blocking net arranged on the side wall of the outer cylinder end portion on one side of the blowing end of the fan.

[0027] The beneficial effect of adopting the above further solution is that the screen can effectively prevent impurities, such as dust, particles, etc., from entering the inner part of the outer cylinder from the blowing end of the fan.

[0028] Furthermore, the interception assembly also includes a mounting ring fixedly connected to one end of the outer cylinder away from the blocking net, and a plurality of parallel and spaced interception screws are installed inside the mounting ring, and the external threads of the plurality of interception screws are sleeved with the same connecting plate, and the outer cylinder is connected to an electric push rod for driving the connecting plate to move along the length direction of the interception screw.

[0029] The beneficial effect of adopting the above-mentioned further scheme is that impurities can be blocked by multiple parallel intercepting screws, and because the intercepting screws are arranged at the air inlet, when larger impurities are attached to one side of the multiple intercepting screws under the drive of the fan, the electric push rod is started, and the electric push rod drives the connecting plate to move. During the movement, the connecting plate drives the multiple intercepting screws to rotate in the same direction, so that the multiple intercepting screws can play a role similar to a conveyor belt to transport the impurities adsorbed on one side of the multiple intercepting screws to one side, so that the air can smoothly enter the inner part of the outer cylinder from one end of the outer cylinder.

[0030] Furthermore, the connecting plate is fixedly connected with slag remover teeth at a position between two adjacent intercepting screws.

[0031] The beneficial effect of adopting the above further solution is that the slag remover teeth can effectively remove impurities and particles attached to the interception screw. During the operation of the fan, the interception screw may intercept some larger impurities or particles, which may adhere to the screw, affecting the filtering effect of the screw and the normal operation of the fan. As the connecting plate moves, the slag remover teeth can continuously scrape the surface of the screw, scraping off the impurities and particles on it, keeping the screw clean and unobstructed.

[0037] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0038] A station kitchen monitoring and alarm system includes a combustible gas detector 1, a cut-off solenoid valve 2, an explosion-proof fan 3, an audible and visual alarm 4 and an alarm control cabinet 5. The combustible gas detector 1, the cut-off solenoid valve 2, the explosion-proof fan 3 and the audible and visual alarm 4 are all electrically connected to the alarm control cabinet 5. The combustible gas detector 1 is installed in the station kitchen, the cut-off solenoid valve 2 is installed at the inlet end of the air intake pipeline of the station kitchen, the air inlet of the explosion-proof fan 3 is connected to the station kitchen, and the air outlet of the explosion-proof fan 3 is connected to the outdoors of the station kitchen.

[0039] The system can detect the concentration of combustible gas in the kitchen in real time through the combustible gas detector 1 installed in the station kitchen. Once the concentration exceeds the safety threshold, the alarm control cabinet 5 will immediately start the sound and light alarm 4, send out sound and light signals, and remind personnel to take timely countermeasures to avoid fire or explosion accidents.

[0040] At the same time, the system can automatically cut off the gas source. The cut-off solenoid valve 2 installed at the inlet end of the kitchen air intake pipeline cuts off the gas source after receiving the instruction issued by the alarm control cabinet 5 according to the concentration of combustible gas exceeding the concentration safety threshold, preventing the combustible gas from continuing to flow into the kitchen, thereby effectively preventing the accident from expanding. In addition, the explosion-proof fan 3 is started for exhaust. The explosion-proof fan 3 is connected to the station kitchen to quickly discharge the combustible gas in the kitchen to the outside, reduce the concentration of combustible gas in the kitchen, and further reduce the risk of accidents.

[0041] By installing the fire detector 8, the fire hazard in the kitchen can be monitored in real time. When the fire detector 8 detects signs of fire in the station kitchen, the alarm control cabinet 5 will immediately start the sound and light alarm 4, send out sound and light signals, and at the same time, the solenoid valve 2 will cut off the gas source after receiving the instruction issued by the alarm control cabinet 5 according to the signs of fire in the station kitchen, thereby improving the safety of the station kitchen.

[0042] Preferably, the combustible gas detector 1 is an infrared combustible gas detector, and the fire detector 8 is a temperature detector. The infrared combustible gas detector can adapt to harsh environmental conditions, and its detection speed is faster and more robust. This allows the infrared combustible gas detector 1 to still work stably and reliably in an environment where there may be multiple interference factors, such as a station kitchen.

[0043] The temperature detector can detect temperature changes around the fire source, has a fast and sensitive response speed, and can promptly detect fire hazards. When the temperature detector detects that the temperature in the station kitchen exceeds the temperature safety threshold, the alarm controller 5 activates the sound and light alarm 4 to remind on-site personnel to take timely measures for rescue, thereby avoiding the occurrence of fire accidents.

[0044] Preferably, the sound and light alarm 4 is arranged on the top of the alarm control cabinet 5 .

[0045] The sound and light alarm 4 is located at the top of the alarm control cabinet 5, which is relatively high and can better attract people's attention. Once the concentration of combustible gas is detected to exceed the safety threshold, the sound and light alarm 4 will emit a loud sound and obvious flash, so that the on-site personnel can quickly detect and respond and take necessary safety measures in time.

[0046] Preferably, the explosion-proof fan 3 is an explosion-proof axial flow fan, and the explosion-proof fan 3 is installed on the wall of the station kitchen. The high air volume characteristic of the axial flow fan helps to quickly remove the fumes and harmful gases in the kitchen.

[0047] Preferably, the station kitchen combustible gas monitoring and alarm system also includes an indoor explosion-proof operating column 6 and an outdoor explosion-proof operating column 7, both of which are connected to the explosion-proof fan 3, and the indoor explosion-proof operating column 6 is provided with a first start button and a first stop button, and the outdoor explosion-proof operating column 7 is provided with a second start button and a second stop button, the indoor explosion-proof operating column 6 is installed in the station kitchen, and the outdoor explosion-proof operating column 7 is installed outside the station kitchen, and the indoor explosion-proof operating column 6 and the outdoor explosion-proof operating column 7 are both used to control the start and stop of the explosion-proof fan 3.

[0048] The first start button and the first stop button provided on the indoor explosion-proof operating column 6 enable the staff to conveniently and directly control the operation of the explosion-proof fan 3 inside the kitchen. This close-range operation mode not only improves the convenience of operation, but also helps the staff to adjust the operating state of the explosion-proof fan 3 in time according to actual conditions. The provision of the outdoor explosion-proof operating column 7 enables the staff to control the explosion-proof fan 3 not only inside the kitchen, but also outside the kitchen. This flexible operation mode allows the staff to select the most convenient and safest position to control the operation of the explosion-proof fan 3 according to actual needs, thereby improving work efficiency.

[0049] It should be noted that the outdoor explosion-proof operating column 7 is also equipped with a remote communication module, through which the explosion-proof fan 32 can be remotely controlled. This allows managers to understand the operating status of the explosion-proof fan 3 in real time, discover and deal with potential safety hazards in a timely manner, and improve the intelligence level of the entire system.

[0050] As an optional implementation of the embodiment of the present application, Figure 2 and Figure 3 As shown, the explosion-proof fan 3 includes an outer cylinder 31 , a fan 32 is arranged inside the outer cylinder 31 , a motor 33 is connected to one side of the fan 32 , and interception components are installed at both ends of the outer cylinder 31 , and the interception components are used to prevent impurities from entering the inner part of the outer cylinder 31 .

[0051] The interception assembly includes a screen 34 disposed at the side wall of the end of the outer cylinder 31 on the blowing end side of the fan 32. The screen 34 can be a louver type, and the louver type screen 34 has the function of adjusting the ventilation volume, and the angle of the blades can be adjusted as needed to control the air intake. The screen 34 can also be a fine metal mesh or plastic mesh to prevent tiny particles and dust from entering the fan and ensure the normal operation of the fan. At the same time, the metal mesh or plastic mesh material also has high strength and durability, and can withstand a certain degree of impact and wear.

[0052] The interception assembly also includes a mounting ring 35 fixedly connected to one end of the outer cylinder 31 away from the interception net 34, and a plurality of parallel and spaced interception screws 36 are installed inside the mounting ring 35. The external threads of the plurality of interception screws 36 are sleeved with the same connecting plate 37, and the outer cylinder 31 is connected to an electric push rod 38 for driving the connecting plate 37 to move along the length direction of the interception screw 36. The connecting plate 37 is fixedly connected to a slag remover tooth 39 at a position between two adjacent interception screws 36.

[0053] Impurities can be blocked by multiple parallel intercepting screws 36, and because the intercepting screws 36 are arranged at the air inlet, when larger impurities are attached to one side of the multiple intercepting screws 36 driven by the fan 32, the electric push rod 38 is started, and the electric push rod 38 drives the connecting plate 37 to move. During the movement, the connecting plate 37 drives the multiple intercepting screws 36 to rotate in the same direction, so that the multiple intercepting screws 36 can play a role similar to a conveyor belt to transport the impurities adsorbed on one side of the multiple intercepting screws 36 to one side, so that the air can smoothly enter the inner part of the outer tube 31 from one end of the outer tube 31.

[0054] During the operation of the fan, the intercepting screw 36 may intercept some larger impurities or particles, which may adhere to the screw, affecting the filtering effect of the screw and the normal operation of the fan. When the electric push rod 38 drives the connecting plate 37 to move, the multiple slag removing teeth 39 on the connecting plate 37 move, and the slag removing teeth 39 can effectively remove the impurities and particles attached to the intercepting screw 36.

[0055] The implementation principle of a station kitchen monitoring and alarm system provided by this application is:

[0056] The combustible gas concentration in the station kitchen is detected by the combustible gas detector 1. When the combustible gas concentration in the station kitchen exceeds the safety threshold, the alarm control cabinet 5 starts the sound and light alarm 4 to alarm. At the same time, the alarm control cabinet 5 controls the cut-off solenoid valve 2 to close, thereby cutting off the gas source and preventing the combustible gas from continuing to flow into the kitchen, thereby effectively preventing the accident from expanding. At the same time, the alarm control cabinet 5 controls the explosion-proof fan 3 to start, quickly exhausting the combustible gas in the kitchen to the outdoors, reducing the combustible gas concentration in the kitchen and further reducing the risk of accidents.

[0057] When the fire detector 8 detects signs of fire in the station kitchen, the alarm control cabinet 5 will immediately start the sound and light alarm 4, emit sound and light signals, and at the same time, after receiving the instruction issued by the alarm control cabinet 5 based on the signs of fire in the station kitchen, the solenoid valve 2 cuts off the gas source to improve the safety of the station kitchen.

[0058] When the explosion-proof fan 3 is started, the electric push rod 38 is started and drives the connecting plate 37 to move. During the movement of the connecting plate 37, the connecting plate 37 drives the multiple intercepting screws 36 to rotate in the same direction, so that the multiple intercepting screws 36 can play a role similar to a conveyor belt to transport the impurities adsorbed on one side of the multiple intercepting screws 36 to one side, so that the air can smoothly enter the outer cylinder 31 from one end of the outer cylinder 31. When the electric push rod 38 drives the connecting plate 37 to move, the multiple slag teeth 39 on the connecting plate 37 move, and the slag teeth 39 can effectively remove the impurities and particles attached to the intercepting screws 36.
