Description

Technical Field

[0001] The present invention relates to the field of fire fighting technology, and in particular to a fire fighting transition control system, method and storage medium. Background Art

[0002] Fire pumps refer to special fire water pumps or ordinary clean water pumps that meet the national standard "Fire Pump Performance Requirements and Test Methods" GB 6245, which are used to provide sufficient water to meet the needs of fire fighting when a fire occurs. According to the working principle and structural characteristics, fire pumps can be divided into centrifugal pumps, mixed flow pumps, axial flow pumps, screw pumps, etc. The working principle is: when a fire alarm signal is received, the motor of the fire pump starts and drives the impeller to rotate. The rotation of the impeller generates centrifugal force or other forces, which enables the liquid in the pump to gain energy and form a pressure difference, thereby pushing the water or other fire extinguishing agents stored in the water tank to the sprinklers, fire hydrants and other fire extinguishing equipment to form water mist, water column or foam for fire extinguishing.

[0003] The water outlet of the fire pump is generally used to connect with the connecting hose, which is connected to the gun head. A valve is set on the gun head to control the water or other fire extinguishing agents from the gun body nozzle. When the firefighters use the fire pump to extinguish the fire and transfer, they can first close the valve on the gun head, and then transfer it to another location and then open the valve on the gun head to extinguish the fire. This can prevent the connecting hose from accidentally dragging, colliding, etc. during the transfer process, causing the water gun to spray by mistake, avoiding accidental injuries to the firefighters themselves and the surrounding personnel, and preventing water from spraying everywhere and causing unnecessary damage to the surrounding objects and the environment. However, after the valve on the gun head is closed, the fire pump does not stop running, and it will continue to fill with liquid, which will cause the connecting hose to swell and the pipe to increase in weight after filling with liquid, which brings great inconvenience to the transfer. In addition, the continuous operation of the fire pump will cause the water in the connecting hose to be continuously pressurized, causing the pressure in the pipe to rise sharply, which not only has the risk of bursting and leakage, but also affects the normal operation of the fire protection system, and has great safety hazards.

[0004] In view of this, the present invention provides a new solution to solve the above problem. Summary of the invention

[0020] The present invention will be further described below.

[0021] The present invention provides a firefighting transfer control system, method and storage medium, which solves the technical problem that the movement of the connecting hose 3 caused by the swelling of the connecting hose 3 after filling with liquid and the increase in weight of the pipe after filling with liquid remains unchanged during the transfer process when the firefighter closes the gun head 2. The technical principle of the swelling of the connecting hose 3 after filling with liquid also needs to be understood by comprehensively applying the knowledge related to centrifugal pumps and fluid mechanics.

[0022] From the perspective of centrifugal pump characteristics, there is a general rule in its flow-head curve: when the flow gradually increases, the head decreases accordingly; when the flow is zero, it corresponds to the "dead point head", and the dead point head value is usually significantly higher than the head at the normal delivery flow. For example, when the centrifugal pump outlet pipe 5 is in a closed state, but the centrifugal pump still maintains operation, the dead point head is reached at this time. In this case, a higher pressure will be generated on the centrifugal pump outlet pipe 5.

[0023] In the field of fluid mechanics, the Bernoulli equation, also known as the steady flow energy equation, is applicable to the steady flow of ideal fluids. The equation shows that in the flow of fluids ignoring viscosity losses, the sum of the pressure potential energy, kinetic energy and potential energy of any two points on the streamline always remains constant. Specifically, when the fluid in the pipe flows normally, it contains a certain amount of energy. If the flow rate is suddenly reduced to 0, the kinetic energy of the fluid will be converted into pressure potential energy in large quantities, which will cause the static pressure to increase rapidly.

[0024] The existing conventional technical solution is to connect the two ends of the connecting hose 3 to the outlet pipe 5 of the fire pump 1 and the gun head 2 respectively. After the fire pump 1 is started, the liquid for fire extinguishing (such as water) is sucked from the inlet pipeline of the fire pump 1, and is transported to the connecting hose 3 through the outlet pipe 5 after the pressurization of the impeller inside the fire pump 1, and finally ejected from the gun head 2. When the actual firefighting operation needs to be transferred, if the firefighter suddenly closes the valve of the gun head 2, the delivery flow of the fire pump 1 will drop to zero instantly, but the fire pump 1 is still running, which makes the pressure of the outlet pipe 5 of the fire pump 1 increase sharply, reaching the high pressure state corresponding to the "dead point head". At the same time, the flow rate of the liquid in the connecting hose 3 and the gun head 2 drops significantly, and the kinetic energy of the liquid is converted into pressure potential energy. These two factors work together to cause the entire fluid area from the outlet pipe 5 of the fire pump 1 to the gun head 2 to be in a high static pressure state. This will not only cause the connecting hose 3 to swell excessively and become hard, which will bring great difficulties to the firefighters in the process of dragging the connecting hose 3 to the transfer site; it will also easily cause a pipe burst accident, resulting in leakage problems in the pipe wall of the connecting hose 3 and the joints between the connecting hose 3 and the outlet pipe 5 of the fire pump 1 and the gun head 2, and in severe cases, the connecting hose 3 may even fall off from the joint. In addition, when the connecting hose 3 is filled with liquid, it will cause a large weight regardless of the pressure in the pipe, which brings great inconvenience to the transfer site and is time-consuming and laborious.

[0025] Based on this, the present invention provides a firefighting transfer control system, method and storage medium. Once it is detected that the firefighters are transferring, the pressure connection between the connecting hose 3 and the fire pump 1 is first cut off, and then the connecting hose 3 is temporarily drained and depressurized with the help of the storage tank 4. Through this process, on the one hand, the liquid (such as water) in the connecting hose 3 can be released to reduce the weight of the connecting hose 3 and facilitate the transfer. On the other hand, the static pressure in the connecting hose 3 and the gun head 2 can be greatly reduced, effectively solving a series of problems such as bulging, bursting and leakage of the connecting hose 3. The entire device of the present invention has a simple structure, low cost, stable and reliable operation, and can be realized by simply modifying the existing design of the fire pump 1.

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] Embodiment 1: A firefighting transfer control system, method and storage medium, such as Figure 1 As shown, the firefighting transfer control system includes a fire pump 1, a gun head 2, a storage tank 4, a controller, and a connecting hose 3 for connecting the gun head 2 and the fire pump 1. The outlet of the fire pump 1 is provided with an outlet pipe 5, one end of the connecting hose 3 is flange-connected to the outlet pipe 5, and the other end is connected to the gun head 2. When the firefighter enters the fire scene with the gun head 2 to extinguish the fire, the fire pump 1 drives the firefighting liquid (water) into the connecting hose 3, and then it is sprayed out by the gun head 2.

[0028] Preferably, a third valve 10 is installed at the water outlet of the gun head 2 for opening or closing the gun head 2.

[0029] The storage tank 4 is provided for the purpose of relieving pressure and removing the fire-fighting fluid (water) in the connecting hose 3. A pressure relief pipe 6 is connected to the storage tank 4. One end of the pressure relief pipe 6 is connected to the outlet pipe 5, and the other end is connected to the storage tank 4. A second valve 9 is installed on the pressure relief pipe 6 for controlling the connection between the connecting hose 3 and the storage tank 4.

[0030] Preferably, the second valve 9 is a normally closed valve so that the fire pump 1 is closed when in operation to prevent the fire-fighting fluid from leaking from the pressure relief pipe 6 .

[0031] In order to allow the fire fighting liquid (water) in the connecting hose 3 to smoothly enter the storage tank 4, preferably, a vent hole is opened on the top of the storage tank 4, and a breathable film is installed in the vent hole to connect the storage tank 4 with the outside atmosphere.

[0032] Preferably, a discharge valve 11 is provided at the bottom of the storage tank 4 to discharge the liquid in the storage tank 4 .

[0033] Preferably, a liquid level meter is installed on the storage tank 4 to monitor the height of the liquid material in real time. When the storage tank 4 contains a lot of liquid, the discharge valve 11 can be opened to discharge the liquid.

[0034] In the above technical solution, firefighters need to frequently transfer when extinguishing fires, that is, they need to move to different locations to extinguish fires according to the specific fire situation. When transferring, firefighters will actively close the third valve 10, and the firefighting liquid will stop spraying. Since the fire pump 1 is still running, once the third valve 10 is closed, the connecting hose 3 will swell due to continuous filling, the pressure will rise sharply, and the pipe will increase in weight after filling, making it very inconvenient to move. For this reason, the present invention is provided with a storage tank 4, which allows the firefighting liquid (water) in the connecting hose 3 to enter the storage tank 4 through the pressure relief pipe 6, thereby reducing the weight of the connecting hose 3 and the pressure in the connecting hose 3.

[0035] Reference Figure 1 The gun head 2 is also provided with a positioning chip 13, which is a GPS or Beidou positioning chip 13. In this embodiment, the positioning chip 13 is a GPS positioning chip 13. The outlet pipe 5 of the fire pump 1 is provided with a first valve 8 and a pressure gauge 7. The first valve 8 is installed at the front end of the connection between the outlet pipe 5 and the pressure relief pipe 6, and the pressure gauge 7 is installed at the rear end of the connection between the outlet pipe 5 and the pressure relief pipe 6. The pressure gauge 7 is used to monitor the pressure in the connecting hose 3 in real time. The controller is electrically connected to the first valve 8, the second valve 9, the third valve 10, the positioning chip 13 and the pressure gauge 7 respectively.

[0036] Preferably, the first valve 8 and the second valve 9 are both electric gate valves.

[0037] In the above technical solution, by setting the pressure relief pipe 6 and controlling the opening and closing of the first valve 8 and the second valve 9, the pressure in the connecting hose 3 is released into the storage tank 4. Specifically, during the use of the fire pump 1, two operations are included: pressure relief operation and pressure charging operation. The pressure relief operation is started when the transfer is completed, and the pressure charging operation is started after the transfer is completed. The pressure relief operation includes two steps: closing the first valve 8 and opening the second valve 9. The first valve 8 is closed first, and then the second valve 9 is opened to separate the fire pump 1 from the connecting hose 3, and the connecting hose 3 is connected to the pressure relief pipe 6. In this way, the fire-fighting liquid in the connecting hose 3 will enter the storage tank 4 through the pressure relief pipe 6, reducing the weight of the connecting hose 3 and reducing the pressure in the connecting hose 3. The pressure charging operation includes two steps: closing the second valve 9 and opening the first valve 8. The second valve 9 is closed first, and then the first valve 8 is opened to connect the fire pump 1 with the connecting hose 3, and the connecting hose 3 is separated from the pressure relief pipe 6. In this way, the fire-fighting liquid transported by the fire pump 1 will enter the gun head 2 through the connecting hose 3.

[0038] Reference Figure 1 The controller is used to control the automatic switching of pressure charging operation and pressure relief operation to improve the automation level of the fire transfer control system.

[0039] Preferably, the controller is a programmable logic controller (PLC) or an industrial control computer.

[0040] The controller may set a preset time t1 and a preset distance threshold s1 to determine whether the pressure relief operation is turned on.

[0041] The controller may set a preset time t2 and a preset distance threshold s2 to determine whether the charging operation is turned on.

[0042] The controller may set a pressure threshold and a pressure stability value to determine whether to start a pressure relief operation or a pressure charging operation.

[0043] Preferably, a button 12 is provided on the gun head 2, and the button 12 is electrically connected to the controller. Specifically, the button 12 is wirelessly connected to the controller.

[0044] The button 12 is arranged on the gun head 2, and the firefighter can manually switch between the pressure charging operation and the pressure relief operation by controlling the button 12 according to specific needs, which greatly facilitates the operation of the firefighter.

[0045] The fire fighting transfer control method comprises the following steps: S1. When the third valve 10 is closed, the moving distance of the gun head 2 within the preset time t1 is obtained, and the real-time pressure at the outlet of the fire pump 1 is obtained, and the real-time pressure is compared with the pressure threshold. When the real-time pressure is greater than the pressure threshold and when the moving distance is greater than the preset distance threshold s1, the pressure relief operation is started, and the pressure relief operation includes closing the first valve 8 and opening the second valve 9.

[0046] In the above steps, the preset time t1, the preset distance threshold s1, and the pressure threshold are all pre-stored in the memory of the controller, and the pressure threshold is configured to be able to withstand the connection hose 3. The real-time pressure is the pressure of the connection hose 3 obtained by the pressure gauge 7. The comparison between the real-time pressure and the pressure threshold will generate a comparison result. When the comparison result is: the real-time pressure is greater than the pressure threshold and the moving distance is greater than the preset distance threshold s1, the pressure relief operation is started. At this time, the controller sends the first control signal and the second control signal to the first valve 8 and the second valve 9 in turn. The first valve 8 closes in response to the first control signal; the second valve 9 opens in response to the second control signal. In summary, when the firefighter closes the third valve 10, a transition judgment will be made first. When the real-time pressure is greater than the pressure threshold and the moving distance is greater than the preset distance threshold s1, it is judged that the firefighter is transitioning, thereby starting the pressure relief operation.

[0047] S2. After the third valve 10 is opened, the moving distance of the gun head 2 within the preset time t2 is obtained, and the real-time pressure at the outlet of the fire pump 1 is obtained, and the real-time pressure is compared with the pressure stability value. When the real-time pressure is less than the pressure stability value and when the moving distance is less than the preset distance threshold s2, the pressure charging operation is started. The pressure charging operation includes closing the second valve 9 and opening the first valve 8.

[0048] In the above steps, the preset time t2, the preset distance threshold s2, and the pressure stability value are all pre-stored in the memory of the controller. The real-time pressure is the pressure of the connecting hose 3 obtained by the pressure gauge 7. The comparison between the real-time pressure and the pressure threshold will generate a comparison result. When the comparison result is: when the real-time pressure is less than the pressure stability value and when the moving distance is less than the preset distance threshold s2, the charging operation is started. At this time, the controller sends the third control signal and the fourth control signal to the first valve 8 and the second valve 9 in turn. The second valve 9 is closed in response to the third control signal; the first valve 8 is opened in response to the fourth control signal. In summary, when the firefighter opens the third valve 10, a transition judgment will be made first. When the real-time pressure is less than the pressure stability value and when the moving distance is less than the preset distance threshold s2, it is judged that the firefighter's transition is completed, thereby starting the charging operation so that the fire-fighting fluid can be sprayed from the gun head 2.

[0049] The pressure stabilization value is much smaller than the pressure threshold value so that the switching between the pressure charging operation and the pressure releasing operation is not too frequent.

[0050] Preferably, the pressure threshold is 80% to 95% of the dead-point head of the fire pump 1 .

[0051] The present invention significantly improves the accuracy of pressure relief control and system safety through dual-condition joint triggering and multi-parameter collaborative judgment.

[0052] The present invention also provides a storage medium, which is a computer-readable storage medium, and stores a fire transition control program on the storage medium, wherein when the fire transition control program is executed by a processor, the steps of the above-mentioned fire transition control method are implemented.

[0053] Embodiment 2: A firefighting transfer control system, method and storage medium, which are different from Example 1 in that: The fire fighting transfer control method comprises the following steps: S1, when the third valve 10 is closed, the moving distance of the gun head 2 within the preset time t1 is obtained, and when the moving distance is greater than the preset distance threshold s1, the pressure relief operation is started, and the pressure relief operation includes closing the first valve 8 and opening the second valve 9; S2. After the third valve 10 is opened, the moving distance of the gun head 2 within the preset time t2 is obtained. When the moving distance is less than the preset distance threshold s2, the pressurizing operation is started. The pressurizing operation includes closing the second valve 9 and opening the first valve 8. The pressurizing operation includes closing the second valve 9 and opening the first valve 8.

[0054] The present invention uses only the moving distance of the gun head 2 as a judgment parameter, and a single condition triggers the pressure relief, so the outlet pipe 5 of the fire pump 1 does not need to be installed with a pressure gauge 7.

[0055] Embodiment 3: A firefighting transfer control system, method and storage medium, which are different from Example 1 in that: The fire fighting transfer control method comprises the following steps: S1. When the third valve 10 is closed, the real-time pressure at the outlet of the fire pump 1 is obtained, and the real-time pressure is compared with the pressure threshold. When the real-time pressure is greater than the pressure threshold, the pressure relief operation is started, and the pressure relief operation includes closing the first valve 8 and opening the second valve 9; S2. After the third valve 10 is opened, the real-time pressure at the outlet of the fire pump 1 is obtained, and the real-time pressure is compared with the pressure stability value. When the real-time pressure is less than the pressure stability value, the pressure charging operation is started. The pressure charging operation includes closing the second valve 9 and opening the first valve 8.

[0056] The present invention uses only pressure change as a judgment parameter, and a single condition triggers pressure relief.

[0057] Application examples: In this embodiment, the fire pump 1 is a motor-driven clean water centrifugal pump with a dead-point head of 65m. During normal transportation, the head of the fire pump 1 is between 30m and 45m, and the pressure threshold is 80% of the dead-point head of the fire pump 1, that is, the pressure corresponding to 52m of water column.

[0058] During a firefighting operation, firefighters were performing firefighting operations at position A, and the measured value of the pressure gauge 7 was maintained at 40m±3m water column. Suddenly, the firefighters closed the third valve 10, and the measured value of the pressure gauge 7 soared to 53m water column. The controller immediately issued a command to close the first valve 8 and then open the second valve 9.

[0059] After 3 seconds, the pressure value drops below the pressure stability value, and the fire pump 1 is also in a standby state ready to supply fluid at any time.

[0060] 5 seconds later, the firefighters moved to position B and opened the third valve 10. At this time, the controller issued another command to close the second valve 9 and open the first valve 8, so that the fire pump 1 continued to provide high-pressure liquid to be sprayed out from the gun head 2.

[0061] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
