Description

Technical Field

[0001] This invention relates to the field of tunnel fire hydrant monitoring and emergency control technology, specifically a fully automatic status monitoring and emergency remote control device for tunnel fire hydrants. Background Technology

[0002] Tunnel fire protection facilities are very important and need to be kept in normal working order at all times. Effective monitoring of tunnel fire protection facilities is necessary to ensure their normal operation in the event of a dangerous situation.

[0003] When a dangerous situation occurs, it is necessary to quickly address the location of the danger, such as... Figure 1 As shown, when not in use, the coil 6 is in a rolled-up state. In its flat, rolled-up state, the coil 6 is equivalent to a closed water valve and cannot deliver water.

[0004] After the main water supply pipe is turned on, the coil 6 needs to be fully deployed, and the water outlet of the coil 6 can only spray fire water to the emergency location after the liquid inside the coil 6 has reached full saturation. This process will take some time, thus delaying the handling of the emergency.

[0005] Therefore, a fully automatic status monitoring and emergency remote control device for tunnel fire hydrants is proposed to address the above issues. Summary of the Invention

[0006] The purpose of this invention is to provide a fully automatic status monitoring and emergency remote control device for tunnel fire hydrants, which can effectively monitor the water pressure and water film level inside the fire hydrant in real time. Most importantly, it can effectively shorten the time from the deployment of the coil to the spraying of water, thereby saving valuable time for fire rescue.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a fully automatic status monitoring and emergency remote control device for tunnel fire hydrants, comprising a cabinet-type fire hydrant and a control module on top of the fire hydrant. The lower layer of the fire hydrant is equipped with a main water supply pipe and an aqueous film-forming tank. The main water supply pipe is equipped with an electric main valve for controlling its opening and closing and a pressure sensor for detecting internal pressure. The pressure sensor extends into the inner side of the main water supply pipe to monitor pressure. A liquid level sensor is installed at the bottom of the aqueous film-forming tank to obtain the liquid level within the tank. The liquid level sensor is pressure-type and can continuously sense the liquid level data. A liquid replenishment pipe and an exhaust valve are installed on the side of the aqueous film-forming tank.

[0008] The upper layer of the fire hydrant is slidably connected to a U-shaped sliding pipe. The left and right sides of the U-shaped sliding pipe are not connected. The left and right sides of the U-shaped sliding pipe are respectively connected and rotatably connected to a main connecting pipe and a secondary connecting pipe. The inner sides of the main connecting pipe and the secondary connecting pipe are respectively connected and rotatably connected to a main rotating drum and a secondary rotating drum. The outer sides of the main rotating drum and the secondary rotating drum are respectively wound and connected to a coil and a reel. The coil has no internal support and is in a flat and closed shape when there is no internal water pressure and it is wound and stored. The reel has internal support and is in a connected state when it is wound and stored.

[0009] By utilizing the coil's curling and stretching states, the water path can be automatically switched between the coil and the rolled-up coil, and the water inside the coil can be pre-filled. This effectively shortens the time from coil deployment to water spraying out. Compared with existing technologies, it can reduce the time required for docking, thus adding a boost to urgent rescue time.

[0010] In this invention, the opening diameter of the hose is much smaller than that of the coil, so it can be stored in the fire hydrant without being in a "flat" position, and can quickly fill the inside of the coil when it is pulled out.

[0011] The outlet end of the coil is connected to a docking port and a nozzle. The nozzle is equipped with a valve. The end of the reel is connected to a connection port, which can be connected to the docking port. After connection, the inside of the coil that is pulled out in real time can be filled by the reel in advance, avoiding the need for the coil to be fully unfolded before it can become connected and flush, as required by the existing technology. This can effectively shorten the time from unfolding the coil to spraying water. Compared with the existing technology, it can further reduce the time required for docking and add more effort to the urgent rescue time.

[0012] The main water supply pipe in this invention is a fire-fighting pressurized water pipe. In the event of an emergency, this invention does not require manual connection from the main water supply pipe to the water outlet nozzle, which can further reduce the time required for connection compared to the prior art.

[0013] In this invention, upon receiving a fire alarm, remote control is achieved via a control module with remote function, or manual control is achieved by pressing the emergency button on the fire hydrant. The roller shutter door will automatically open, the electric push rod will operate, and the U-shaped sliding tube will slide out of the fire hydrant. Then, personnel will rotate the main connecting pipe and the auxiliary connecting pipe, wherein the main connecting pipe will rotate 88° clockwise and the auxiliary connecting pipe will rotate 88° counterclockwise, exposing the coil and the roller pipe outside the fire hydrant.

[0014] Manually connect the connector to the other connector using either a snap-fit ​​or screw connection. At this time, the electric main valve on the main water supply pipe opens, and the plunger pump starts working. A mixture of water and water film is generated in the main water supply pipe. Because the coil is in a "flat" blocked state, the water in the main water supply pipe will enter the inside of the coil through the secondary pipe, the right-side telescopic hose, the inner right side of the U-shaped slide pipe, the secondary connection point, the secondary connecting pipe, the secondary rotary joint, the secondary drum, the reel and connector, and the other connector. The inside of the coil that is pulled out in real time can be pre-filled by the reel. During the process of pulling out the coil, the valve on the nozzle is closed.

[0015] As the coil is fully extended and the valve on the nozzle is opened, the coil is no longer blocked, the passage in the main pipe is opened, the flow rate of the main water supply pipe increases rapidly, and the water in the main water supply pipe will be sprayed out through the main pipe, the telescopic hose on the left, the inner left side of the U-shaped slide pipe, the main connection point, the main connecting pipe, the main rotary joint, the main rotating drum, the coil and the nozzle.

[0016] As a preferred embodiment of the fully automatic status monitoring and emergency remote control device for tunnel fire hydrants of the present invention, the fire hydrant has a sliding groove on the inner side of both the left and right ends, and a slider is slidably connected to the inner side of the sliding groove. The slider is fixedly connected to the outer side of the U-shaped sliding tube. An electric push rod is fixedly connected to the inner side of the sliding groove on the left side. The movable end of the electric push rod is fixedly connected to the slider on that side. The extension of the electric push rod enables the coil to extend out of the fire hydrant.

[0017] As a preferred embodiment of the fully automatic status monitoring and emergency remote control device for tunnel fire hydrants of the present invention, one side of the main connecting pipe is connected to a main connecting point, and one side of the auxiliary connecting pipe is connected to an auxiliary connecting point. The main connecting point and the auxiliary connecting point are respectively rotatably connected to the left and right sides of the U-shaped slide pipe through a third rotary joint. The fixed end of the left third rotary joint is connected to and fixedly connected to the left side of the U-shaped slide pipe, and the fixed end of the right third rotary joint is connected to and fixedly connected to the right side of the U-shaped slide pipe. The rotating end of the left third rotary joint is connected to and fixedly connected to the inner side of the main connecting point, and the rotating end of the right third rotary joint is connected to and fixedly connected to the inner side of the auxiliary connecting point.

[0018] Angle compensation during the connection process is achieved through a third rotary joint;

[0019] As a preferred embodiment of the fully automatic status monitoring and emergency remote control device for tunnel fire hydrants of the present invention, the ends of the main connecting pipe and the auxiliary connecting pipe are respectively fixedly connected to a main rotary joint and an auxiliary rotary joint. The rotating end between the two main rotary joints is fixedly connected to and communicates with both ends of the main rotating drum, and the rotating end between the two auxiliary rotary joints is fixedly connected to and communicates with both ends of the auxiliary rotating drum.

[0020] As a preferred embodiment of the fully automatic status monitoring and emergency remote control device for tunnel fire hydrants of the present invention, the main connection point and the auxiliary connection point are respectively connected to the left and right sides of the U-shaped slide pipe through a connecting assembly to achieve rotatable support connection. The connecting assembly includes a connecting ring and an annular female seat. The outer side of the connecting ring and the inner side of the annular female seat are rotatably connected. The connecting ring on the left side is fixedly connected to the main connection point. The annular female seat on the left side is fixedly connected to the left side of the U-shaped slide pipe. The connecting ring on the right side is fixedly connected to the auxiliary connection point. The annular female seat on the right side is fixedly connected to the right side of the U-shaped slide pipe. By increasing the damping coefficient between the connecting ring and the annular female seat, the main connection pipe and the auxiliary connection pipe are prevented from swinging arbitrarily.

[0021] As a preferred embodiment of the fully automatic status monitoring and emergency remote control device for tunnel fire hydrants of the present invention, the rear side of the fire hydrant is a back plate, and the inner side of the back plate is fixedly connected to a main pipe and a secondary pipe. The lower sides of the main pipe and the secondary pipe are connected through a horizontal pipe. The upper outlet ends of the main pipe and the secondary pipe are both connected to a telescopic hose. The main pipe is connected to the left side of the U-shaped slide pipe through the left telescopic hose, and the secondary pipe is connected to the right side of the U-shaped slide pipe through the right telescopic hose. The main water supply pipe is connected to the horizontal pipe.

[0022] As a preferred embodiment of the fully automatic status monitoring and emergency remote control device for tunnel fire hydrants of the present invention, a plunger pump is fixedly connected to the top of the aqueous film-forming tank, the input end of the plunger pump extends into the inner side of the bottom end of the aqueous film-forming tank, and the output end of the plunger pump is connected to the inner side of the main water supply pipe.

[0023] As a preferred embodiment of the fully automatic status monitoring and emergency remote control device for tunnel fire hydrants of the present invention, the electric main valve has a built-in flow rate sensor to obtain the flow rate of the main water supply pipe. As the coil is fully extended and unfolded, the coil is no longer blocked, and the flow rate of the main water supply pipe increases rapidly. When the flow rate sensor detects the increase in the flow rate in the main water supply pipe, it will feed back to the control module to increase the output power of the plunger pump so that the ratio of water film to water is matched.

[0024] As a preferred embodiment of the fully automatic status monitoring and emergency remote control device for tunnel fire hydrants of the present invention, the control module has a wireless transmission function through a cellular network, which can transmit monitoring data back to the control console in real time and realize remote operation in the event of a disaster.

[0025] As a preferred embodiment of the fully automatic status monitoring and emergency remote control device for tunnel fire hydrants of the present invention, a roller shutter door is installed on the upper front side of the fire hydrant. The fire hydrant is opened and closed by rolling up the shutter door, which avoids the side-opening door method in the prior art, which occupies the front space of the fire hydrant and easily causes users to fall backward when opening the door, resulting in the risk of stepping into the ground.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] 1. The tunnel fire hydrant fully automatic status monitoring and emergency remote control device has a pressure sensor that extends into the inside of the main water supply pipe to monitor pressure; a liquid level sensor is installed at the bottom of the aqueous film forming tank to obtain the liquid level in the tank. The liquid level sensor is pressure type and can continuously sense the liquid level data to monitor the status of the fire hydrant.

[0028] 2. The fully automatic status monitoring and emergency remote control device for tunnel fire hydrants, in this invention, has a retractable tube with a much smaller opening diameter than the coil, so it can be stored inside the fire hydrant without being "flat". When the coil is pulled out, it quickly fills the inside of the coil. By utilizing the coil's curling and stretching state, the water path is automatically switched between the coil and the retractable tube, and the water inside the coil is pre-filled, effectively shortening the time from coil deployment to water spraying. Compared with existing technologies, it can reduce the time required for docking, adding a boost to the time needed for urgent rescue.

[0029] 3. The fully automatic status monitoring and emergency remote control device for the tunnel fire hydrant has a connector and nozzle at the outlet end of the coil. The nozzle is equipped with a valve, and the end of the hose is connected to a connection port that can connect to the connector. After connection, the inside of the coil pulled out in real time can be pre-filled by the hose, avoiding the need for the coil to be fully unfolded before it can be connected and flushed, as required by existing technology. This effectively shortens the time from unfolding the coil to spraying water. Compared with existing technology, it can further reduce the time required for docking and add more effort to the urgent rescue time.

[0030] 4. The fully automatic status monitoring and emergency remote control device for tunnel fire hydrants: The main water supply pipe in this invention is a fire-fighting pressurized water pipe. In the event of an emergency, this invention does not require manual connection from the main water supply pipe to the water outlet. Compared with the prior art, it can further reduce the time required for connection.

[0031] 5. This fully automatic status monitoring and emergency remote control device for tunnel fire hydrants, upon receiving a fire alarm, can be remotely controlled via a control module with remote functionality, or manually controlled by pressing the emergency button on the fire hydrant. The roller shutter will automatically open, the electric push rod will operate, and the U-shaped sliding tube will slide out of the fire hydrant. Then, personnel will rotate the main connecting pipe and the auxiliary connecting pipe, with the main connecting pipe rotating 88° clockwise and the auxiliary connecting pipe rotating 88° counterclockwise, exposing the coil and the reel outside the fire hydrant. The connection port will be manually connected to the corresponding interface. At this time, the electric main valve on the main water supply pipe will open, the plunger pump will start working, and a mixture of water and water film will be generated in the main water supply pipe. Because the coil is in a "flat" blocked state, water in the main water supply pipe will enter the inside of the coil, and the inside of the coil pulled out in real time can be pre-filled by the reel. As the coil fully extends and unfolds, the valve on the nozzle is opened, the coil is no longer blocked, the passage in the main pipe is opened, the flow rate of the main water supply pipe increases rapidly, and the water in the main water supply pipe will be sprayed out.

[0032] 6. The fully automatic status monitoring and emergency remote control device for the tunnel fire hydrant has a roller shutter door installed on the upper front side of the fire hydrant. The fire hydrant can be opened and closed by rolling it up. This avoids the side-opening door method in the existing technology, which occupies the front space of the fire hydrant and easily causes users to fall backward when opening the door, resulting in the risk of stepping into the ground.

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] Example 1, please refer to Figure 1-13 This invention provides a technical solution: a fully automatic status monitoring and emergency remote control device for tunnel fire hydrants, including a cabinet-type fire hydrant 1 and a control module 2 on top of the fire hydrant 1. A main water supply pipe 25 and an aqueous film-forming tank 27 are installed on the lower layer of the fire hydrant 1. An electric main valve 28 for controlling opening and closing and a pressure sensor 29 for detecting internal pressure are installed on the main water supply pipe 25. The pressure sensor 29 extends into the inner side of the main water supply pipe 25 to monitor pressure. A liquid level sensor 18 is installed at the bottom of the aqueous film-forming tank 27 to obtain the liquid level inside the tank. The liquid level sensor 18 is pressure-type and can continuously sense liquid level data. A liquid replenishment pipe and an exhaust valve are installed on the side of the aqueous film-forming tank 27.

[0049] The upper layer of the fire hydrant 1 is slidably connected to a U-shaped sliding pipe 4. The left and right sides of the U-shaped sliding pipe 4 are not connected. The left and right sides of the U-shaped sliding pipe 4 are respectively connected and rotatably connected to a main connecting pipe 5 and a secondary connecting pipe 24. The inner sides of the main connecting pipe 5 and the secondary connecting pipe 24 are respectively connected and rotatably connected to a main rotating drum 20 and a secondary rotating drum 21. The outer sides of the main rotating drum 20 and the secondary rotating drum 21 are respectively wound and connected to a coil 6 and a reel 8. The coil 6 has no internal support and is "flat" when wound and stored. The reel 8 has internal support, which can be a circular support. When wound and stored, the inside is in a connected state. The coil 6 is a soft material with an outer braid and an inner rubber.

[0050] In this invention, the opening diameter of the reel 8 is much smaller than that of the coil 6, so it does not occupy a large space. Therefore, it can be stored in the fire hydrant 1 without being "flat". When the coil 6 is pulled out, it plays a role in quickly filling the inside of the coil 6. Compared with the prior art, it can reduce the time required for docking and help save time in urgent rescue.

[0051] The outlet end of the coil 6 is connected to the interface 7 and the nozzle 10. The nozzle 10 is equipped with a valve. The end of the reel 8 is connected to the connection port 9, which can be connected to the interface 7. After connection, the coil 6 pulled out in real time can be filled by the reel 8 in advance, avoiding the need for the coil 6 to be fully unfolded before it can become connected and flush, as required by the existing technology. This can effectively shorten the time from unfolding the coil 6 to spraying water. Compared with the existing technology, it can further reduce the time required for docking and add more effort to the urgent rescue time.

[0052] In this invention, the main water supply pipe 25 is a fire-fighting pressurized water pipe. In the event of an emergency, this invention does not require manual connection from the main water supply pipe 25 to the water outlet nozzle 10. Compared with the prior art, it can further reduce the time required for connection.

[0053] Specifically, the inner sides of both ends of the fire hydrant 1 are provided with sliding grooves, and the inner side of the sliding groove is slidably connected to the slider 15. The slider 15 is fixedly connected to the outer side of the U-shaped sliding tube 4. The inner side of the sliding groove on the left side is fixedly connected to the electric push rod 16. The movable end of the electric push rod 16 is fixedly connected to the slider 15 on that side. The extension of the electric push rod 16 enables the coil 6 to extend out of the fire hydrant 1.

[0054] Specifically, one side of the main connecting pipe 5 is connected to the main connecting point 17, and one side of the auxiliary connecting pipe 24 is connected to the auxiliary connecting point 23. The main connecting point 17 and the auxiliary connecting point 23 are rotatably connected to the left and right sides of the U-shaped slide pipe 4 through the third rotary joint 30, respectively. The fixed end of the left third rotary joint 30 is connected to and fixedly connected to the left side of the U-shaped slide pipe 4, and the fixed end of the right third rotary joint 30 is connected to and fixedly connected to the right side of the U-shaped slide pipe 4. The rotating end of the left third rotary joint 30 is connected to and fixedly connected to the inner side of the main connecting point 17, and the rotating end of the right third rotary joint 30 is connected to and fixedly connected to the inner side of the auxiliary connecting point 23.

[0055] Angle compensation and water flow are achieved during the connection process through the third rotary joint 30;

[0056] Specifically, the ends of the main connecting pipe 5 and the auxiliary connecting pipe 24 are respectively fixedly connected to the main rotary joint 19 and the auxiliary rotary joint 22. The rotating end between the two main rotary joints 19 is fixedly connected to and communicates with both ends of the main rotating drum 20, and the rotating end between the two auxiliary rotary joints 22 is fixedly connected to and communicates with both ends of the auxiliary rotating drum 21.

[0057] Specifically, the main connection point 17 and the auxiliary connection point 23 are rotatably supported and connected to the left and right sides of the U-shaped slide tube 4 respectively through connecting components. The connecting components include a connecting ring 13 and an annular female seat 14. The outer side of the connecting ring 13 and the inner side of the annular female seat 14 are rotatably connected. The left connecting ring 13 is fixedly connected to the main connection point 17, and the left annular female seat 14 is fixedly connected to the left side of the U-shaped slide tube 4. The right connecting ring 13 is fixedly connected to the auxiliary connection point 23, and the right annular female seat 14 is fixedly connected to the right side of the U-shaped slide tube 4. An elastic friction washer is provided between the connecting ring 13 and the annular female seat 14, or friction is generated by tightening with an adjusting screw. By increasing the damping coefficient between the connecting ring 13 and the annular female seat 14, the main connecting tube 5 and the auxiliary connecting tube 24 are prevented from swinging arbitrarily.

[0058] Specifically, the back of fire hydrant 1 is a back plate 101. The inner side of the back plate 101 is fixedly connected to the main pipe 11 and the secondary pipe 12. The lower sides of the main pipe 11 and the secondary pipe 12 are connected through the horizontal pipe 31. The upper outlet ends of the main pipe 11 and the secondary pipe 12 are connected to the telescopic hoses. The main pipe 11 is connected to the left side of the U-shaped slide pipe 4 through the left telescopic hose. The secondary pipe 12 is connected to the right side of the U-shaped slide pipe 4 through the right telescopic hose. The main water supply pipe 25 is connected to the horizontal pipe 31.

[0059] Specifically, a plunger pump 26 is fixedly connected to the top of the aqueous film forming tank 27. The input end of the plunger pump 26 extends into the inner side of the bottom end of the aqueous film forming tank 27, and the output end of the plunger pump 26 is connected to the inner side of the main water supply pipe 25.

[0060] Specifically, the electric main valve 28 has a built-in flow rate sensor to obtain the flow rate of the main water supply pipe 25. As the coil 6 is fully extended and unfolded, the coil 6 is no longer blocked, and the flow rate of the main water supply pipe 25 increases rapidly. When the flow rate sensor detects the increase in the flow rate in the main water supply pipe 25, it will feed back to the control module 2 to increase the output power of the plunger pump 26 so that the ratio of water film to water is matched.

[0061] The flow rate sensor can be one of turbine type, electromagnetic type or ultrasonic type. The flow rate sensor is embedded in the electric main valve 28 or the main water supply pipe 25. The flow rate sensor communicates with the control module 2 through a wired connection.

[0062] Specifically, control module 2 has wireless transmission capabilities via a cellular network, enabling it to transmit monitoring data back to the control console in real time and achieve remote control during disasters. The cellular network is either 4G or 5G, and it is powered by the power supply inside the tunnel, which is existing technology and will not be elaborated further here.

[0063] Specifically, a roller shutter door 3 is installed on the upper front side of the fire hydrant 1. The fire hydrant 1 is opened and closed by rolling up the shutter door. This avoids the side-opening door method in the existing technology, which would occupy the front space of the fire hydrant 1 and easily cause users to fall backward when opening the door, resulting in the risk of falling into the ground.

[0064] In this invention, upon receiving a fire alarm, remote control is achieved via the control module 2 with remote function, or manual control is achieved by pressing the emergency button on the fire hydrant 1. The roller shutter door 3 will automatically open, the electric push rod 16 will operate, and the U-shaped sliding pipe 4 will slide out of the fire hydrant 1. Then, personnel will rotate the main connecting pipe 5 and the auxiliary connecting pipe 24, wherein the main connecting pipe 5 will rotate 88° clockwise and the auxiliary connecting pipe 24 will rotate 88° counterclockwise, exposing the coil 6 and the roller 8 outside the fire hydrant 1.

[0065] Manually connect the connector 9 to the connector 7. The connection method is either a snap-fit ​​connection or a spiral connection. At this time, the electric main valve 28 on the main water supply pipe 25 is opened, and the plunger pump 26 starts to work. A mixture of water and water film is generated in the main water supply pipe 25. Because the coil 6 is in a "flat" blocked state, the water in the main water supply pipe 25 will enter the inside of the coil 6 through the secondary pipe 12, the right-side telescopic hose, the inner right side of the U-shaped slide pipe 4, the secondary connection point 23, the secondary connection pipe 24, the secondary rotary joint 22, the secondary rotary drum 21, the coil 8, the connector 9, and the connector 7. After connection, the inside of the coil 6 that is pulled out in real time can be filled in advance by the coil 8. During the process of pulling out the coil 6, the valve on the nozzle 10 is in the closed state.

[0066] As the coil 6 is fully extended and the valve on the nozzle 10 is opened, the coil 6 is no longer blocked, the passage where the main pipe 11 is located is opened, the flow rate of the main water supply pipe 25 increases rapidly, and the water in the main water supply pipe 25 will be sprayed out through the main pipe 11, the telescopic hose on the left, the inner left side of the U-shaped slide pipe 4, the main connection point 17, the main connection pipe 5, the main rotary joint 19, the main rotating drum 20, the coil 6 and the nozzle 10.

[0067] This avoids the need for the coil 6 to be fully extended before it can become connected and flush, as is required in existing technologies, thus effectively shortening the time from when the coil 6 is extended to when water is sprayed out.

[0068] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
