Description

Technical Field

[0001] The invention relates to the technical field of fire monitoring, in particular to mobile electrical fire monitoring equipment for high-pressure fine water mist fire fighting. Background Art

[0002] Mobile high-pressure fine water mist fire-fighting electrical fire monitoring equipment is a device used to detect and extinguish early electrical fires. It is suitable for early rapid detection of electrical fires in electrical lines below 10kV in industrial and civil buildings. The equipment combines drone technology and infrared camera technology to replace manual entry into the early fire scene. The staff remotely detects the fire scene through the display of the control terminal and locates the fire source according to the ambient temperature, smoke concentration and infrared data. Once the fire source is found, the equipment will activate the sound and light alarm system to warn people to stay away and send the fire source information to the control terminal, so that the staff can use high-pressure fine water mist to extinguish the fire source in time, or control the fire. After the fire source is extinguished, the staff will turn off the alarm system through the control terminal and inspect other locations of the fire scene.

[0003] During the operation of the infrared monitoring equipment, when the infrared monitoring equipment enters the indoor environment for detection, because the indoor environment is closed, the high-temperature smoke is not easy to diffuse outward, causing the concentration of the indoor high-temperature smoke to gradually increase. At this time, too much high-temperature smoke will affect the performance of the infrared monitoring equipment, causing the detection range of the infrared monitoring equipment to be reduced, thereby delaying the discovery of the fire source, sound and light alarms, and fire extinguishing. In addition, when the electrical fire monitoring equipment is close to a violently burning fire source, there is a risk that the electrical fire monitoring equipment will be damaged by an explosion at the fire source, affecting the equipment's alarm and fire extinguishing work.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. It is only stated that the directional words such as upper, lower, left and right that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0021] Mobile high pressure water mist fire fighting electrical fire monitoring equipment, reference Figure 1-Figure 4 , including: a base 1, the base 1 is fixedly connected with a fixing frame 2, a first protective shell 101 and a second protective shell 102, an audible and visual alarm 1012 is installed on the first protective shell 101, the fixing frame 2 is provided with a power part 3, a water storage tank, a temperature monitoring module, a smoke concentration monitoring module and a communication module are installed on the base 1, and the communication module is used to collect the temperature, surrounding smoke concentration, water volume, oil volume, battery voltage, startup record, and position related information on the fine water mist vehicle and feed it back to the fire electrical fire monitoring network system; a spray head 4, installed on the power part 3, a liquid spray head 5 is installed in the spray head 4, the liquid spray head 5 is connected with the water storage tank, and the spray head 4 is used to spray airflow in the direction of the liquid spray head 5; an infrared camera 6, installed on the spray head 4; an air supply mechanism, arranged on the upper side of the base 1, is used to supply air to the spray head 4.

[0022] The above scheme aims to overcome the disadvantage that the detection range of infrared monitoring equipment is reduced due to the influence of high-temperature smoke when used in indoor fire scenes. A water tank, an oil tank, a battery and a power wheel are installed on the base 1, wherein the power wheel, the temperature monitoring module, the smoke concentration monitoring module, the communication module, the sound and light alarm 1012, the power part 3, the liquid spray head 5, the infrared camera 6 and the gas supply mechanism are all electrically connected to the control terminal. The communication module adopts RS485 standard communication and adopts IP65 design to ensure the stability and reliability of the communication module in an environment with high smoke concentration. The communication module has the functions of recording the startup record, the travel route record and the specific positioning of the device, so that the staff can grasp the specific situation in the fire scene according to the driving record of the device, and the communication module is equipped with a 2.4-inch LCD display screen, which is convenient for the staff to read the information of the device at close range, so as to facilitate the staff to perform daily maintenance on the device. The power part 3 is a power structure similar to the camera gimbal, which is used to drive the spray head 4 and its components to rotate, so that the spray head 4 can detect and aim at the fire source, and the connecting part 8 is connected to the gas cylinder. The connection part 7 is a hard structure (such as alloy material) for fixing the connecting member 8. The connection part between the connecting member 8 and the injection head 4 is a soft structure (such as a hose structure), which is convenient for the power member 3 to drive the injection head 4 to rotate freely. The temperature monitoring module and the smoke concentration monitoring module are both existing devices, which are used to monitor the fire situation around the device, so as to transmit more accurate fire information to the staff. The control terminal remotely operates the device to work automatically through the communication module, or manually operates the fire scene detection work. The first protective shell 101 and the second protective shell 102 are hard high-temperature resistant composite materials (such as ceramic-based composite materials, metal-based composite materials and carbon-based composite materials), which are used to protect the safety of key components of the electrical fire monitoring equipment (such as batteries, water tanks and oil tanks, etc.) in the fire scene. The sound and light alarm 1012, the temperature monitoring module and the smoke concentration monitoring module are all installed on the outside of the first protective shell 101, so that the sound and light alarm 1012, the temperature monitoring module and the smoke concentration monitoring module can monitor the surrounding environment of the device and effectively warn the surrounding personnel.

[0023] The working process of the above scheme is as follows: when an electrical fire occurs, the staff places the device at the entrance of the fire scene, and then the staff operates the device through the control terminal to enter the fire scene. After the device enters the fire scene, due to the high-temperature smoke scattered in the small space indoors, it is difficult for the staff to distinguish the indoor structure through the display of the control terminal (that is, the picture sent back by the infrared camera 6). At this time, the staff controls the power part 3 through the control terminal to drive the injection head 4 and its components to rotate, so that the injection head 4 is aimed at the direction in which the device is about to move (or the direction that needs to be explored). Then the staff controls the liquid spray head 5 through the control terminal to spray a high-pressure fine water mist in the direction in which the injection head 4 is aimed, and at the same time controls the air supply mechanism through the control terminal to supply air to the injection head 4. At this time, the high Driven by the airflow, the high-pressure water mist quickly diffuses in the direction of the spray head 5. During the diffusion process, the high-pressure water mist and the airflow drive the high-temperature flue gas passing through the area to move together, temporarily reducing the flue gas concentration and temperature at the position where the infrared camera 6 is aimed (that is, the position where the spray head 4 is aimed), which is convenient for expanding the effective monitoring range of the infrared camera 6, and then facilitating the staff to identify the indoor structure and explore the fire source location. The control terminal immediately closes the spray head 5 and the air supply mechanism after controlling the spray head 5 and the air supply mechanism to spray briefly (that is, this high-pressure water mist and airflow only last for a short time, forming only an airflow wave that diffuses outward), to avoid continuous spraying that causes the surrounding high-temperature flue gas to quickly converge to the position where the spray head 4 is aimed, thereby blocking the detection range of the infrared camera 6.

[0024] The staff repeatedly uses the above principle to explore the fire scene until the infrared camera 6 captures the location of the fire source. At this time, the control terminal alarms and emphasizes the location of the fire source on the display of the control terminal. At the same time, the above-mentioned short-term spraying of high-pressure fine water mist is repeated, so that the staff can confirm the details of the fire source through the display, that is, whether the fire source is a false alarm, etc. When the staff confirms that the place is the fire source, the staff activates the sound and light alarm 1012 through the control terminal to warn the people who may be left in the fire scene to stay away from the place, and aims the spray head 4 at the location of the fire source, and controls the spray head 5 to spray continuous high-pressure fine water mist to extinguish the fire (or to suppress the spread of the fire source). When the fire source is extinguished, the staff turns off the sound and light alarm 1012 through the control terminal, and inspects other locations according to the same steps as above to monitor and confirm the specific situation in the fire scene.

[0025] Preferably, refer to Figure 2-Figure 6The air supply mechanism includes: an air cylinder 7, which is fixedly connected to the upper side of the base 1. The air cylinder 7 is fixedly connected to a connecting piece 8 through a support rod. The air cylinder 7 and the injection head 4 are both connected to the connecting piece 8; an electric push rod 9, which is fixedly connected to the upper side of the base 1. The telescopic end of the electric push rod 9 is fixedly connected to an extrusion rod 10. The extrusion rod 10 is sealed and slidably connected to the air cylinder 7. A one-way valve 1001 is fixedly connected to the extrusion rod 10; a force storage component is arranged on the air cylinder 7, and is used to increase the pressure of the gas in the air cylinder 7.

[0026] Preferably, referring to FIG. 4 , the flow area of ​​the side of the injection head 4 away from the connection member 8 is smaller than the flow area at the connection point between the injection head 4 and the connection member 8 .

[0027] The above scheme aims to specifically disclose an air supply mechanism, in which the size of the cavity in the gas storage cylinder 7 is larger than the size of the cavity in the injection head 4, and at the same time, the flow area on the side of the injection head 4 away from the connecting piece 8 is smaller than the flow area on the side of the injection head 4 close to the connecting piece 8, so that when the gas in the gas storage cylinder 7 is ejected from the injection head 4, the speed of the airflow ejected from the injection head 4 is increased, and then the speed and distance of the airflow carrying the surrounding smoke and high-pressure fine water mist to diffuse outward after the injection head 4 ejects a short airflow are increased. The electric push rod 9 is electrically connected to the control terminal, and the one-way valve 1001 can only allow the gas outside the gas storage cylinder 7 to flow between the gas storage cylinder 7 and the extrusion rod 10 (that is, the telescopic end of the electric push rod 9 drives the extrusion rod 10 When the ejector head 4 moves to the left), it is used to replenish the gas in the gas cylinder 7. When the ejector head 4 needs to spray air toward the aligned position, the control terminal controls the telescopic end of the electric push rod 9 to drive the extrusion rod 10 to move to the right. At this time, the force storage component temporarily blocks the connection between the connecting piece 8 and the gas cylinder 7 to increase the pressure of the gas in the gas cylinder 7. When the telescopic end of the electric push rod 9 moves to a certain position, the force storage component automatically opens, and the gas in the gas cylinder 7 flows into the ejector head 4 through the connecting piece 8, and is ejected from the ejector head 4 to the position where the ejector head 4 is aligned, forming a strong airflow to enhance the effect of the airflow driving the surrounding smoke and high-pressure fine water mist to diffuse outward. Subsequently, the force storage component automatically resets when the telescopic end of the electric push rod 9 is reset.

[0028] Preferably, refer to Figure 5 and Figure 6 The force storage component includes: a blocking member 11, which is slidably connected to the outside of the air cylinder 7, and a first elastic member is installed between the two. The blocking member 11 is provided with a connecting hole 111, and the air cylinder 7 and the connecting member 8 are both connected and matched with the connecting hole 111; an extrusion ring 12, which is slidably connected to the outside of the extrusion rod 10, and the extrusion ring 12 is extruded and matched with the blocking member 11; a quick unlocking component, which is arranged on the connecting member 8, and is used to increase the instantaneous moving speed of the blocking member 11.

[0029] Preferably, refer to Figure 7The quick unlocking component includes: a limiting ball 13, which is slidably connected to the connecting member 8, and a second elastic member is installed between the two. The limiting ball 13 is limitedly matched with the blocking member 11, and a third elastic member is installed between the extrusion ring 12 and the extrusion rod 10.

[0030] In the above scheme, it is intended to specifically disclose a force storage component, the first elastic member is a tension spring, the second elastic member is a spring, and the third elastic member is a tension spring. The elastic coefficient of the first elastic member is smaller than the elastic coefficient of the third elastic member. The limiting ball 13 can be replaced by any part that limits the blocking member 11 through the elastic force of the second elastic member. The limiting ball 13 limits the blocking member 11 by inserting it into the connecting hole 111. When the control terminal controls the telescopic end of the electric push rod 9 to drive the extrusion rod 10 to move from left to right, the connecting hole 111 is staggered with the connecting part of the gas cylinder 7 and the connecting member 8, and the gas in the gas cylinder 7 cannot flow into the connecting member 8. The gas in the gas cylinder 7 stores force, and the extrusion rod 10 drives the extrusion ring 12 to move together through the third elastic member. When the extrusion ring 12 contacts the blocking member 11, the limiting ball 13 is located in the connecting hole 111, and the blocking member 11 and the extrusion ring 12 cannot follow the extrusion rod under the limitation of the limiting ball 13. 10 moves together, the third elastic member stretches and accumulates force, and when the elastic force of the third elastic member increases, the extrusion ring 12 and the sealing member 11 are driven by the third elastic member to gradually squeeze the limiting ball 13 to retract into the connecting member 8, the second elastic member is compressed and accumulates force, and the first elastic member is stretched and accumulates force, and the limiting ball 13 gradually releases the limit on the sealing member 11. When the limiting ball 13 completely releases the limit on the sealing member 11, the extrusion ring 12 and the sealing member 11 move rapidly to the right under the elastic force of the third elastic member, and the connecting hole 111 moves rapidly to a position aligned with the connection between the gas storage cylinder 7 and the connecting member 8, so that the gas in the gas storage cylinder 7 quickly flows out from the connecting member 8 and the injection head 4. When the control terminal controls the telescopic end of the electric push rod 9 to drive the extrusion rod 10 to move to the left and reset, the sealing member 11 moves and resets under the action of the first elastic member, and the limiting ball 13 continues to be inserted into the connecting hole 111 under the action of the second elastic member to limit the sealing member 11.

[0031] Preferably, refer to Figure 2-Figure 4 , and also includes: an air guide mechanism, which is arranged on the upper side of the injection head 4 and is used to guide the smoke to gather in a specific direction. The air guide mechanism includes: a ventilator 14, which is fixed to the upper side of the injection head 4, and the ventilator 14 is equipped with symmetrically distributed air guide heads 15; an electric fan 16, which is installed in the ventilator 14.

[0032] Preferably, the symmetrically distributed air guide heads 15 are tilted toward the back side at the sides away from the air cylinder 14 , and the sides of the air guide heads 15 away from the air cylinder 14 are tilted toward the upper side of the injection head 4 .

[0033] Preferably, refer to Figure 3 and Figure 4 , further comprising: a filter element 17 fixedly connected to the ventilator 14.

[0034] In the above scheme, a specific air guide mechanism is proposed, which continues to operate after the device enters the fire scene. The air guide mechanism is used to continuously blow airflow toward the upper side of the direction in which the nozzle head 4 is aimed, guide the surrounding high-temperature smoke to gather toward the airflow, and thereby reduce the situation in which the high-temperature smoke gathers toward the direction in which the nozzle head 4 is aimed. The electric fan 16 is electrically connected to the control terminal, and the air guide head 15 is tilted toward the upper side of the direction in which the nozzle head 4 is aimed, thereby guiding the surrounding high-temperature smoke to converge toward the upper side of the direction in which the nozzle head 4 is aimed. The sum of the flow areas of the two air guide heads 15 is smaller than the flow area of ​​the ventilator 14, and is used to enhance the intensity of the airflow blown out by the air guide head 15, thereby increasing the range of smoke flow affected by the air guide head 15. The filter 17 is a filter cotton structure, which is used to reduce the smoke content in the airflow blown out of the ventilator 14, thereby reducing the probability of the electric fan 16 being stuck due to sticky smoke particles.

[0035] In all the above solutions, the fixing frame 2 and the power member 3 are considered to be fixedly connected, while in the following solutions, the fixing frame 2 and the power member 3 are slidably connected to facilitate the power member 3 to slide along the fixing frame 2 and enter the second protective shell 102.

[0036] Preferably, refer to Figure 1 , Figure 2 and Figure 8 , and also includes: a protection mechanism, which is arranged in the base 1 and is used to protect the infrared camera 6. The protection mechanism includes: a first limit member 18, which has two symmetrically distributed ones, both of which are slidably connected to the upper side of the fixing frame 2, a fourth elastic member is installed between the first limit member 18 and the fixing frame 2, and the first limit member 18 is limited and matched with the power member 3; the number of electromagnetic blocks 19 is equal to that of the first limit members 18, and both are fixed in the second protective shell 102, and the electromagnetic blocks 19 are magnetically matched with the adjacent first limit members 18; the baffle 20 is limited and rotatably connected to the first protective shell 101, and a fifth elastic member is installed between the two, and the baffle 20 is pressed and matched with the ventilator 14; the fixed plate 21 has two symmetrically distributed ones, both of which are fixed to the upper side of the second protective shell 102, the fixed plate 21 is slidably connected to the second limit member 22, and a sixth elastic member is installed between the two, the second limit member 22 is limited and matched with the baffle 20, the fixing frame 2 is slidably connected to the power member 3, and a seventh elastic member is installed between the two.

[0037] Preferably, the side of the first limiting member 18 close to the power member 3 is made of a brittle material.

[0038] The above scheme aims to propose a protective mechanism that uses the second protective shell 102 to protect valuable components such as the infrared camera 6, thereby reducing the probability of damage to key components such as the infrared camera 6 when a sudden explosion occurs in a fire scene. The soft structure of the connecting member 8 has a large tensile and bending capacity (such as a bellows structure), the fourth elastic member is a tension spring, the fifth elastic member is a torsion spring, the sixth elastic member is a spring, and the seventh elastic member is a tension spring, wherein the fifth elastic member and the seventh elastic member are initially in a power storage state, a spray head 1011 is installed on the upper side of the first protective shell 101, and the spray head 1011 is connected to a water tank for spraying high-pressure fine water mist to the surroundings to extinguish the fire, and the spray head 1011 and the electromagnetic block 19 are both connected to the control terminal Electrical connection, the baffle 20, the fixing plate 21 and the second limiter 22 are all made of high-temperature resistant alloy materials. When the temperature monitoring module and the smoke concentration monitoring module detect that the ambient temperature and smoke concentration of the device are sharply increased, the temperature monitoring module and the smoke concentration monitoring module transmit the data to the control terminal, and the control terminal promptly starts the two electromagnetic blocks 19, and the electromagnetic blocks 19 attract the adjacent first limiter 18 to move to the outside of the fixing frame 2, so that the first limiter 18 releases the limit on the power member 3, and the fourth elastic member stretches and accumulates force. The power member 3 moves downward under the pulling force of the seventh elastic member, and the power member 3 and its upper parts are all moved into the second protective shell 102, and the ventilator 14 stops squeezing the baffle 20. The baffle 20 is under the action of the fifth elastic member. The second limiting member 22 is used to limit the position of the baffle 20, thereby protecting the upper side of the injection head 4, thereby preventing the power member 3 and its components from being damaged when an explosion occurs around the device. The control terminal simultaneously activates the sound and light alarm 1012, and controls the spray head 1011 to spray high-pressure fine water mist around the device to reduce the risk of explosion around the device. When an explosion suddenly occurs around the device, if the explosion site is within the detection field of the infrared camera 6 (i.e., the right side of the device), the infrared camera 6 detects the abnormal temperature rise in advance, thereby reminding the staff to control the device away from the explosion area to avoid explosion damage. If the explosion site is located in the monitoring blind area of ​​the infrared camera 6 (i.e., the left side, upper side, and front and rear sides of the device), and the temperature monitoring module and the smoke concentration monitoring module fail to detect data abnormalities in a timely manner, at this time, by designing the side of the first limiting member 18 close to the power member (3) to be a high-temperature resistant brittle material (such as a high-temperature resistant ceramic sheet, etc.), even if an explosion occurs, the air wave generated by the explosion will first squeeze the baffle plate 20 to swing downward when it fluctuates. During the swinging process, the baffle plate 20 forcibly squeezes the power member 3 to move downward, squeezes and breaks the first limiting member 18, and releases the first limiting member 18 from limiting the power member 3, so that the power member 3 and its components are retracted into the second protective shell 102 in time, thereby improving the protection effect of the infrared camera 6.

[0039] Although the present invention is described in detail with reference to the above embodiments, it is obvious to those skilled in the art through this disclosure that various changes or modifications may be made to the present invention without departing from the principles and spirit of the present invention. Therefore, the detailed description of the embodiments of the present disclosure is only used to explain, rather than to limit the present invention.
