Description

Technical Field

[0001] This utility model relates to the technical field of ignition fuel supply system for fire simulation training facilities, specifically a ignition fuel supply system for fire simulation training facilities. Background Technology

[0002] When firefighters conduct realistic fire simulation training, fuel oil is typically used as the combustion medium to recreate complex fire scenarios such as those involving chemical facilities, oil tanks, and gas storage tanks, as well as the combustion patterns of various flammable media and materials. This helps firefighters conduct more effective fire rescue training and practical instruction.

[0003] Currently, training devices used to simulate fire scenarios in chemical facilities, oil tanks, and gas storage tanks generally use fuel oil as the combustion medium. However, during use, factors such as differences in the height of the real flame combustion devices and varying supply pipeline lengths lead to uneven supply pressures among the devices, resulting in inconsistent fire sizes during training. This affects the effectiveness of simulated fire rescue training. Therefore, to improve the quality of fire rescue and practical teaching and ensure training effectiveness, it is particularly necessary to design a simple, easy-to-maintain, and reliable ignition point fuel oil supply system for fire simulation training facilities. Utility Model Content

[0004] To address the shortcomings of existing technologies, such as the varying heights of the real flame combustion devices and the different lengths of the supply pipelines, which lead to inconsistent fire sizes during training and affect the effectiveness of real fire simulation rescue training, this utility model proposes a ignition fuel supply system for fire-fighting real fire simulation training facilities.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a ignition fuel supply system for a fire simulation training facility, including a fuel tank, a controller installed on the top of the fuel tank, a fuel supply ignition mechanism installed on one side of the fuel tank, a pressure relief pipe installed at one end of the fuel supply ignition mechanism, and a return fuel pipe installed at the other end of the fuel supply ignition mechanism.

[0006] The fuel supply and ignition mechanism includes a fuel outlet located on one side of the fuel tank. A first filter is installed at one end of the fuel outlet, a booster pump is installed at one end of the first filter, and a fuel distributor is installed at one end of the booster pump. An electronic pressure gauge is installed on the top of the fuel distributor. A pressure relief pipe is connected to the fuel distributor. A high-fire fuel supply branch pipe is installed on one side of the fuel distributor, and a low-fire fuel supply branch pipe is installed near the bottom of the high-fire fuel supply branch pipe on the same side of the fuel distributor. An igniter is installed at the end of both the high-fire and low-fire fuel supply branch pipes. Both the high-fire and low-fire fuel supply branch pipes are connected to the return fuel pipe. A proportional regulating valve is installed on the outer wall of the pressure relief pipe.

[0007] Preferably, one end of the return oil pipe is connected to the oil tank, and the other end of the return oil pipe is equipped with a return oil pump, and one end of the return oil pump is equipped with a third filter.

[0008] Preferably, a manifold is provided at one end of the third filter, and both the high-fire fuel supply branch pipe and the low-fire fuel supply branch pipe are connected to the manifold.

[0009] Preferably, a second filter is provided on one side of the oil distributor, one end of the second filter is connected to a pressure relief pipe, and one end of the pressure relief pipe is connected to the oil tank.

[0010] Preferably, the outer wall of the pressure relief pipe is provided with a first parallel pipe, and the proportional regulating valve is provided on the outer wall of the first parallel pipe.

[0011] Preferably, a second parallel pipe is provided on the outer wall of the pressure relief pipe near the first parallel pipe, and a safety valve is provided on the outer wall of the second parallel pipe.

[0012] Preferably, a submersible pump is installed on the top of the oil tank, one end of which extends into the inner cavity of the oil tank. A level gauge is installed in the inner cavity of the oil tank, and a breather valve is installed near the level gauge in the inner cavity of the oil tank.

[0013] The advantages of this utility model are:

[0014] This invention involves setting a preset fuel pressure value on the controller. Upon system startup, a booster pump draws fuel from the tank. The fuel flows through the outlet, fuel distributor, high-fire fuel supply branch pipe, and low-fire fuel supply branch pipe. A pressure relief pipe connects to the fuel distributor to regulate the fuel pressure. The igniter then ignites the fuel. The controller monitors the fuel supply pressure in real time using an electronic pressure gauge. When multiple igniters operate simultaneously, if the fuel pressure is lower than the preset value, the controller adjusts the opening angle of the proportional control valve to decrease, reducing the return fuel from the pressure relief pipe and gradually increasing the fuel pressure in the high-fire and low-fire fuel supply branch pipes. Until it reaches the preset value, when the number of igniters is reduced, the fuel pressure in the high-fire fuel supply branch pipe and the low-fire fuel supply branch pipe is greater than the preset value. The controller controls the opening angle of the proportional regulating valve to increase, which increases the return oil in the pressure relief pipe. The fuel pressure in the high-fire fuel supply branch pipe and the low-fire fuel supply branch pipe gradually decreases until it reaches the preset value. This achieves the effect of adaptive adjustment of fuel supply pressure and solves the problem that the fire size of the high-fire combustion device is different during the training process due to factors such as the height difference of the high-fire combustion device and the length of the supply pipeline, which affects the effect of high-fire simulation rescue training.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses a ignition fuel supply system for a fire simulation training facility. (Refer to...) Figures 1-5 A ignition fuel supply system for a fire simulation training facility includes a fuel tank 1, a controller 2 mounted on top of the fuel tank 1, a fuel supply ignition mechanism 3 mounted on one side of the fuel tank 1, a pressure relief pipe 4 mounted on one end of the fuel supply ignition mechanism 3, and a return oil pipe 5 mounted on the other end of the fuel supply ignition mechanism 3. A proportional regulating valve 43 is mounted on the outer wall of the pressure relief pipe 4. By setting a preset fuel pressure value in the controller 2, the fuel supply ignition mechanism 3 draws fuel from the fuel tank 1. The controller 2 monitors the fuel pressure in the fuel supply ignition mechanism 3 in real time. When the fuel pressure in the fuel supply ignition mechanism 3 is less than the preset value, the controller 2 controls the opening angle of the proportional regulating valve 43 to decrease, resulting in a smaller return oil flow from the pressure relief pipe 4. The fuel pressure in the fuel supply ignition mechanism 3 gradually increases until it reaches the preset value. When the fuel pressure in the fuel supply ignition mechanism 3 increases, the controller 2 controls the opening angle of the proportional regulating valve 43 to increase, resulting in a larger return oil flow from the pressure relief pipe 4. The fuel pressure in the fuel supply ignition mechanism 3 gradually decreases until it reaches the preset value, thereby achieving the purpose of adaptive adjustment of fuel supply pressure.

[0025] The fuel supply and ignition mechanism 3 includes a fuel outlet 31, which is located on one side of the fuel tank 1. A first filter 38 is installed at one end of the fuel outlet 31, a booster pump 32 is installed at one end of the first filter 38, and a fuel distributor 33 is installed at one end of the booster pump 32. An electronic pressure gauge 34 is installed on the top of the fuel distributor 33, and a pressure relief pipe 4 is connected to the fuel distributor 33. A high-fire fuel supply branch pipe 35 is installed on one side of the fuel distributor 33, and a low-fire fuel supply branch pipe 36 is installed on one side of the fuel distributor 33 near the bottom of the high-fire fuel supply branch pipe 35. An igniter 37 is installed at the end of both the high-fire fuel supply branch pipe 35 and the low-fire fuel supply branch pipe 36. Both the high-fire fuel supply branch pipe 35 and the low-fire fuel supply branch pipe 36 are connected to the return fuel pipe 5. The booster pump 32 draws fuel from the fuel tank 1. After being filtered by the first filter 38, the fuel flows into the fuel distributor 33, which distributes the fuel to the high-fire fuel supply branch pipe 35, the low-fire fuel supply branch pipe 36, and the pressure relief pipe 4. The igniter 37 ignites the fuel in conjunction with fire drills. The electronic pressure gauge 34 can detect the fuel supply pressure in the fuel distributor 33 in real time and feed it back to the controller 2. The controller 2 adjusts the opening angle of the proportional regulating valve 43 to achieve adaptive adjustment of the fuel supply pressure. In this embodiment, the fuel distributor 33 is a prior art technology. The fuel distributor 33, also known as a fuel distributor, is an important component of the air / fuel subsystem in the electronic fuel injection system. Its main function is to provide a stable fuel flow to each pipeline branch and achieve uniform distribution.

[0026] Reference Figure 1 and Figure 3 One end of the return oil pipe 5 is connected to the fuel tank 1, and the other end of the return oil pipe 5 is equipped with a return oil pump 52. One end of the return oil pump 52 is equipped with a third filter 51, and one end of the third filter 51 is equipped with a manifold 53. The high-fire fuel supply branch pipe 35 and the low-fire fuel supply branch pipe 36 are both connected to the manifold 53. When the system is finished running, the return oil pipe 5 is connected to the fuel tank 1, and the return oil pump 52 is used to pump the remaining fuel in the high-fire fuel supply branch pipe 35 and the low-fire fuel supply branch pipe 36 back to the fuel tank 1. The second filter 41 filters the remaining fuel to facilitate fuel recycling and reuse, thereby avoiding potential safety hazards.

[0027] Reference Figure 2 , Figure 3 and Figure 5A second filter 41 is installed on one side of the fuel distributor 33. One end of the second filter 41 is connected to the pressure relief pipe 4, and the other end of the pressure relief pipe 4 is connected to the fuel tank 1. A first parallel pipe 42 is installed on the outer wall of the pressure relief pipe 4. A proportional regulating valve 43 is installed on the outer wall of the first parallel pipe 42. A second parallel pipe 44 is installed on the outer wall of the pressure relief pipe 4 near the first parallel pipe 42. A safety valve 45 is installed on the outer wall of the second parallel pipe 44. When multiple igniters 37 work simultaneously, the fuel supply in the high-fire fuel supply branch pipe 35 and the low-fire fuel supply branch pipe 36 decreases. The pressure value fed back by the electronic pressure gauge 34 is less than the preset value of the controller 2. The controller 2 controls the opening angle of the proportional regulating valve 43 to decrease, thereby reducing the backflow of fuel in the first parallel pipe 42. This causes a decrease in fuel return in the pressure relief pipe 4, and the fuel pressure in the main fire fuel supply branch pipe 35 and the secondary fire fuel supply branch pipe 36 gradually increases until it reaches the preset value. When the number of igniters 37 is reduced, the controller 2 controls the proportional regulating valve 43 to increase its opening angle, which increases the fuel return in the first parallel pipe 42, leading to an increase in fuel return in the pressure relief pipe 4. The fuel pressure in the main fire fuel supply branch pipe 35 and the secondary fire fuel supply branch pipe 36 gradually decreases until it reaches the preset value, thereby achieving the purpose of adaptive adjustment of the fuel pressure in the main fire fuel supply branch pipe 35 and the secondary fire fuel supply branch pipe 36. The safety valve 45 is used to control the pressure of the fuel supply pipeline to ensure that it does not exceed the set maximum pressure threshold, so as to improve the safety of the system.

[0028] Reference Figure 1 and Figure 4 A submersible pump 21 is installed on the top of the fuel tank 1. One end of the submersible pump 21 extends into the inner cavity of the fuel tank 1. A level gauge 22 is installed in the inner cavity of the fuel tank 1. A breather valve 11 is installed in the inner cavity of the fuel tank 1 near the level gauge 22. When fuel is drawn out of the fuel tank 1, causing the pressure in the upper gas space of the fuel tank 1 to decrease and reach the negative pressure operating point of the breather valve 11, the outside atmosphere will open the negative pressure valve disc of the breather valve 11, allowing outside gas to enter the fuel tank 1, preventing the pressure inside the fuel tank 1 from dropping further, and achieving a balance of gas pressure inside and outside the fuel tank 1 to protect the safety of the fuel tank 1. Through the cooperation of the level gauge 22 and the submersible pump 21, when the fuel level in the fuel tank 1 is low, external fuel can be pumped into the fuel tank 1 through the submersible pump 21, thus facilitating the refueling of the fuel tank 1.

[0029] Working Principle: During use, fuel is drawn from fuel tank 1 using fuel supply and ignition mechanism 3. Booster pump 32 is activated, and fuel flows from outlet 31 through first filter 38 into fuel distributor 33. Fuel distributor 33 distributes fuel to pressure relief pipe 4, high-fire fuel supply branch pipe 35, and low-fire fuel supply branch pipe 36. Ignition device 37 continuously ignites fuel for live-fire training. When multiple ignition devices 37 operate simultaneously, electronic pressure gauge 34 detects a decrease in fuel supply pressure within fuel distributor 33. Controller 2 adjusts the opening angle of proportional regulating valve 43 on first parallel pipe 42, reducing the fuel return pressure in pressure relief pipe 4. The fuel pressure in high-fire and low-fire fuel supply branch pipes 35 and 36 gradually increases until a preset value is reached. Second filter 41 filters fuel, facilitating fuel return in pressure relief pipe 4. Safety valve 45 on 44 is used to control the pressure of the fuel supply pipeline to ensure that it does not exceed the set maximum pressure threshold and improve the safety of system use. When the level gauge 22 detects that the fuel in the fuel tank 1 is low, the submersible pump 21 is turned on to draw external fuel to replenish the fuel tank 1. Through the breather valve 11, when the medium is drawn out from the fuel tank 1, the pressure in the upper gas space of the fuel tank 1 decreases and reaches the negative pressure operating point of the breather valve 11, the outside atmosphere will open the negative pressure valve disc of the breather valve 11, allowing outside gas to enter the fuel tank 1, preventing the pressure in the fuel tank 1 from dropping further, and achieving the balance of the gas pressure inside and outside the fuel tank 1 to protect the safety of the fuel tank 1. When the system stops running, the return oil pipe 5 is connected to the fuel tank 1, and the return oil pump 52 pumps the remaining fuel back to the fuel tank 1 through the manifold 53. The third filter 51 filters the remaining fuel to facilitate fuel recovery and reuse.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
