[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. The following is an explanation of the embodiments of the utility model based on its overall structure.

[0024] The specific implementation of the utility model is as follows:

[0025] As attached Figure 1-4As shown, a fire fighting equipment integrated demonstration system for various application places includes a main water tank 1, a secondary water tank 2, a main water supply pipe 3, and a secondary water supply pipe 4. The main water supply pipe 3 and the auxiliary water supply pipe 4 are provided with a pressure-stabilizing pump 5, a manual stop valve 6, a check valve 7, and a water pump outlet pressure-stabilizing valve 8. The tail ends of the main water supply pipe 3 and the auxiliary water supply pipe 4 are connected to a water main pipe 9 through a three-way structure. The water main pipe 9 is connected with a plurality of branch pipes 10, and each branch pipe 10 is respectively connected with a wet sprinkler alarm system 11, a water curtain sprinkler alarm system 12 and a pre-action sprinkler alarm system 13. A drainage trough 16 is provided on one side of the water main pipe 9, and a plurality of transparent demonstration boxes 17 are provided on the drainage trough 16. Each of the transparent demonstration boxes 17 is respectively provided with a fire-fighting pipe 14 connected to the water outlet end of the wet sprinkler alarm system 11, the water curtain sprinkler alarm system 12 and the pre-action sprinkler alarm system 13 and a fire-fighting induction nozzle 15 arranged at the end of the fire-fighting pipe 14. The transparent demonstration box 17 is provided with a trigger mechanism 18 for triggering the fire-fighting induction nozzle 15 to spray water.

[0026] In this integrated fire equipment demonstration system for various application places, multiple systems are integrated together, water supply is unified through the water supply system, drainage is unified through the drainage system, and demonstrations of multiple systems are integrated to improve the efficiency of safety training and save equipment costs.

[0027] Furthermore, the trigger mechanism 18 includes a long-handled igniter, and a through hole is provided on the wall of one of the transparent demonstration boxes 17, and the long-handled igniter can pass through the through hole and extend into the fire-fighting induction nozzle 15 in the transparent demonstration box 17. During the actual demonstration, after the long-handled igniter extends under the fire-fighting induction nozzle 15, it ignites and heats the fire-fighting induction nozzle 15. The fire-fighting induction nozzle 15 is heated, and under the action of heat, it starts automatically within a predetermined temperature range, sends out a fire signal, and triggers water spraying to extinguish the fire; the trainees can intuitively observe the process of triggering water spraying after the fire-fighting induction nozzle 15 is heated, so that the trainees can quickly understand the working principle of the fire protection system.

[0028] Furthermore, a drain port 21 is provided on the top wall of the water collection and drainage trough 16. The drain port 21 is a square hole. The four sides of the drain port 21 are provided with support vertical plates 26. The opposite sides of each support vertical plate 26 are vertically provided with support flat plates 27. The bottom outer wall of the transparent demonstration box 17 is provided with an ear plate 28 connected to the support flat plate 27. A bolt structure 29 is provided between the support flat plate 27 and the ear plate 28. In this embodiment, the transparent demonstration box 17 is supported and positioned by the support vertical plates 26 and the support flat plate 27 to prevent the transparent demonstration box 17 from tipping over, and to ensure that the water in the transparent demonstration box 17 can completely flow into the water collection and drainage trough 16 through the drain port 21, so as to avoid overflow and cause the site of the safety training center to be wet and affect the operation of other training equipment.

[0029] Furthermore, a drainage funnel 22 connected to a drainage pipe is provided at one end of the drainage trough 16, a blower 23 is provided at the other end of the drainage trough 16, and a guide ramp 24 is provided on the top wall of the drainage trough 16, which extends obliquely to below the drain port 21; supporting feet 20 are provided on both sides of the bottom of the drainage trough 16. In this embodiment, the guide ramp 24 is provided so that the fire water entering from the drain port 21 can flow to one end of the drainage funnel 22 of the drainage trough 16;

[0030] The blower 23 can speed up the flow of fire water in the drainage trough 16 to the drainage funnel 22 to prevent the fire water from overflowing; moreover, the guide inclined plate 24 has the function of blocking the wind, preventing the wind blown by the blower 23 from entering the transparent demonstration box 17, thereby preventing the water in the transparent demonstration box 17 from being discharged smoothly.

[0031] Furthermore, the bolt structure 29 includes a screw rod, a nut, and a waist-shaped hole provided on the ear plate 28 .

[0032] Furthermore, the support plate 26 is threadedly connected with a tightening screw 25 capable of abutting against the outer wall of the transparent demonstration box 17, and the outer plate surface of the support plate 26 is provided with a connecting plate 19 connected to the top wall of the drainage trough 16 by screws or welding.

[0033] Furthermore, the wet sprinkler alarm system 11 includes a signal butterfly valve on the water supply side, a pressure gauge on the water supply side, a pressure gauge on the system side, a wet alarm valve, a water test valve, an alarm pipeline control valve, a pressure switch, and a hydraulic alarm; when the wet system is in a quasi-working state, the pressure of the water in the pipeline is maintained by pressure-stabilizing facilities such as the main water tank 1, the auxiliary water tank 2, the pressure-stabilizing pump 5, the manual stop valve 6, the check valve 7, and the water pump outlet pressure-stabilizing valve 8. When a fire occurs, under the action of the fire temperature, the thermistor of the fire-fighting sensing sprinkler 15 is activated, the sprinkler opens and starts to spray water. At this time, the water in the pipe network changes from static to flowing, the water flow indicator is activated to send out an electrical signal, and the information of water spraying in a certain area is displayed on the alarm controller; due to the continuous water spraying and pressure relief, the upper water pressure of the wet alarm valve is lower than the lower water pressure, and under the action of the pressure difference, the wet alarm valve that was originally in a closed state automatically opens; at this time, the pressurized water flows to the pipe network through the wet alarm valve, and at the same time opens the channel leading to the hydraulic alarm bell. After the delayer is filled with water, the hydraulic alarm bell sounds an alarm, and the pressure switch is activated and outputs a signal to start the pressure-stabilizing pump 5. After the pressure-stabilizing pump 5 is put into operation, the system startup process is completed.

[0034] Furthermore, the water curtain sprinkler alarm system 12 includes a water supply side signal butterfly valve, a water supply side pressure gauge, a system side pressure gauge, a water curtain sprinkler alarm valve, a water test valve, a manual quick opening valve, a hydraulic alarm, an alarm test valve, and a pressure switch. The water curtain sprinkler alarm system 12 is an automatic water sprinkler fire extinguishing system that mainly functions as a fire blocking, cooling, and isolation system. The fire sensor nozzle 15 on the fire pipe 14 at the output end of the water curtain sprinkler alarm system 12 is a water curtain nozzle; the water curtain sprinkler alarm system 12 is mainly used for locations that require water curtain protection or fireproof partitions, such as being set between various fire protection zones or equipment in an enterprise to prevent the spread of fire, block the radiant heat generated by fire accidents, and guide and dilute leaked flammable, explosive, and harmful gases and liquids.

[0035] Furthermore, the pre-action sprinkler alarm system 13 includes a signal butterfly valve on the water supply side, a pressure gauge on the water supply side, a pressure gauge on the system side, a pre-action sprinkler alarm valve, a water test valve, a manual quick-opening valve, a hydraulic alarm, an alarm pipeline control valve, an alarm test valve, and a pressure switch. When the pre-action sprinkler alarm system 13 is in a quasi-working state, the pressure of the water in the pipe before the inlet of the deluge valve is maintained by the main water tank 1, the auxiliary water tank 2, the pressure-stabilizing pump, the air pressure water supply and other pressure-stabilizing facilities. The pipe after the deluge valve is usually free of water or filled with pressurized gas. The pre-action sprinkler alarm system 13 organically combines the automatic fire detection alarm technology and the automatic water sprinkler fire extinguishing system, and plays a dual protection role for the protected object. The system is usually dry, and can realize the initial alarm of the fire when a fire occurs, and immediately fill the pipe network with water to convert the system into a wet type. This transformation process of the system includes the function of preparatory action, so it is called a pre-action water sprinkler fire extinguishing system. In the non-working state, the system has two conditions in which the pipe after the deluge valve is not filled with gas or filled with low-pressure gas. When a fire occurs, the temperature and smoke detectors installed in the protected area first send out a fire alarm signal. The controller opens the deluge valve while displaying the alarm signal with sound and light, allowing water to enter the pipeline and completing the water filling process in a very short time, turning the system into a wet system. The subsequent actions are the same as those of the wet system. When a fire occurs, the automatic fire alarm system automatically opens the deluge alarm valve, and the water distribution pipe begins to exhaust and fill with water, turning the system into a wet system before the closed fire-fighting induction sprinkler 15 is actuated, and spraying water immediately after the closed fire-fighting induction sprinkler 15 is opened.
