Description

General fire control simulation trainer that puts out a fire

Technical Field

The utility model relates to a general fire-fighting simulation training device for unfolding daily training work of fire fighting, belonging to the technical field of simulation training in the field of fire fighting and damage management.

Background

Fire fighting is a relatively dangerous occupation. Firefighters are often required to perform fire-fighting and rescue tasks at times that are life-threatening, both technically and psychologically a significant challenge. When facing extremely dangerous scenes, the fire-fighting and rescue scene is subjected to intense stimulation or life is threatened to generate fear, tension, confusing emotion and the like, so that improper measures are taken, and accidents often occur in fire disaster rescue.

Fire is a very complex learning environment, is rich in flames, smoke and various huge noise, light and shadow, even toxic gas, and is dangerous everywhere. If the fire experience and risk response awareness of the firefighter are improved by actual combat alone, it is clearly undesirable that such training opportunities be not only small, but also easily put the firefighter in a dangerous situation. Therefore, the construction of the fire-fighting simulation training system can be developed by taking reference to the experience of foreign fire-fighting training and combining the experience of the prior art, and a general fire-fighting simulation training device is developed.

Disclosure of Invention

The utility model aims to solve the technical problems that: develops a set of equipment which contains flame, smog and various huge noise and light shadow and provides a safe and controllable fire-fighting training simulation process. The equipment is required to truly reflect various conditions of a fire scene, and the fire-fighting simulation training process is truly and effectively carried out; meanwhile, the product is convenient to maintain, low in production cost, safe to operate and convenient to popularize and apply.

In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows: the whole system is divided into a plurality of functional modules, namely a flame generating module consisting of a burning disc and a bracket; an igniter individual ignition module; the air supply and water supply module is composed of an external gas pipeline, an external air pipeline and a water supplementing pipeline; a scene module consisting of a built-up sound and smoke generator and lamplight; and a back field control module consisting of a control box and a handheld remote controller.

The principle of the scheme is as follows: the gas is supplied to the combustion disk and the igniter through the external gas pipeline, and the igniter provides long-term fire for the combustion disk. Before combustion, water is injected into the combustion disk through a water supplementing pipeline arranged on the combustion disk, so that the water surface submerges the gas pipeline. The external pipeline is provided with a solenoid valve for controlling a switch, an electric regulating valve for regulating the gas quantity and a flowmeter, and the external pipeline is also provided with an air pipeline, so that the size and the height of flame can be controlled by combining the two. After the fire-fighting training starts, a firefighter can perform fire-extinguishing operation, when the thermal resistor arranged on the combustion disc senses the temperature change of a fire scene, according to a threshold curve preset by the system, when the temperature drops in a large range and reaches a certain preset value, the background of the system gradually reduces the supply quantity of fuel gas through a control box and gradually reduces the acousto-optic smoke effect of a scene module, so that the scene of the fire scene is simulated to be controlled gradually; otherwise, the on-site temperature does not drop significantly within a specified time, the system can determine that the training fails, and the instructor or the system can stop training through the control box or the hand-held remote controller to stop the gas supply and the scene module.

Further, the burning disc is made of stainless steel sheet metal, is high-temperature-resistant and corrosion-resistant, and is firm and durable. All the pipelines and other devices adopt a large number of existing mature devices and standard parts in the market, are convenient to connect and reduce the cost.

Furthermore, the burning disc occupies small space, and adopts a standardized design concept. The single combustion disk can simulate a small fire scene, can also be used together by a plurality of combustion disks, can be spliced into various shapes in different scene scenes, and can simulate large complex fire scene with different scales.

Further, we selected DN25 pipeline to supply fuel gas through thermodynamic calculation and gas supply system flow calculation. And meanwhile, the air pipeline penetrates through the holes in the bottom plate of the combustion disc, and protrudes out of the water-proof cover and sprays combustion air to the flame combustion position. The flame height can be effectively increased, the flame height can be 2.8m high through calculation, and the flame situations of common wood, electronic equipment, oil gas and the like can be effectively simulated.

Furthermore, the application of sound, smoke generator and light effect in the scene module can simulate a realistic fire scene with the freely combined combustion disk.

Further, after the thermal resistor arranged on the combustion disc senses the temperature change of the fire scene, according to a threshold curve preset by the system, when the temperature is reduced in a large range and reaches a certain preset value, the background of the system can gradually reduce the supply quantity of fuel gas through the control box and gradually reduce the acousto-optic smoke effect of the scene module, so that the scene of the fire scene is simulated to be controlled gradually.

Further, the control equipment of the fire-fighting simulation training device consists of a control box and a handheld remote controller. For safety, the control box is arranged at a far position and is responsible for automatically or manually controlling the operation and detection of the whole system; the hand-held remote controller is held by the instructor, and the instructor can take close to the instructor to participate in the training, and when the training is unexpected or other special conditions occur, the instructor can adjust the test condition through the hand-held remote controller or directly stop the training.

Compared with the prior art, the utility model has the following advantages:

(1) By adopting a standardized design concept, the combustion disc can be freely combined to simulate complex ignition sites with different scales, and the device is efficient and convenient to use, and is more practical in training.

(2) The height of the flame after the test can reach 2.8m, so that common fire situations such as wood, electronic equipment, oil gas and the like can be effectively simulated, and the coverage is wide.

(3) The application of the sound-light-shadow scene not only can simulate a vivid fire scene, but also has great promotion effect on the critical consciousness and spirit of firefighters in the firefighting and fire extinguishing training.

(4) The fire extinguishing process is controllable, and the background system adjusts the air inflow by analyzing the temperature change curve of the fire scene, so that the aim of controlling the flame size is fulfilled. The training process is systematic and data, and the instructor and the learner can more intuitively see the training result, thereby being helpful for the fire control skill.

(5) The control box and the hand-held remote controller are provided with double insurance, so that training and adjustment can be guaranteed, and an additional insurance is added for the safety of students and the periphery.

The external air pipeline 5 and the water supplementing pipeline 6 are composed of common DN25 pipes, the ends are provided with electromagnetic valves and loose joints, and the electromagnetic valves and the loose joints are uniformly controlled by the control box 7.

The control module consists of a control box 7 and a hand-held remote controller 8, as shown in figure 1.
