Description

Technical Field

[0001] This utility model relates to the field of fire protection facility testing, and in particular to a fire protection facility testing device based on fire protection engineering. Background Technology

[0002] Fire protection facility inspection based on fire protection engineering refers to the systematic technical means of inspecting, testing, and evaluating various fire protection equipment, systems, and their operational status within buildings or premises to ensure their normal operation in the event of a fire, thereby protecting human life and reducing property damage. Active fire protection facilities include automatic fire alarm systems, automatic sprinkler systems, gas extinguishing systems, smoke control systems, fire emergency lighting, and evacuation guidance systems. Passive fire protection facilities include fire doors, fire-resistant roller shutters, firewalls, fire-retardant coatings, and other flame-retardant structures. Auxiliary equipment includes fire hydrants, fire extinguishers, fire pumps, fire power supplies, and other fire-fighting equipment, all of which require inspection.

[0003] A search revealed that Chinese Patent Publication No. CN222816210U discloses a fire protection facility testing device. By incorporating a movable support mechanism, it solves the problem that in previous fire protection facility testing devices, the fire extinguisher might lean against the inside of the support frame during use, thus affecting the measurement results. The device enables the clamping mechanism and the fire extinguisher to be moved onto a measuring scale so that the measuring scale weighs the fire extinguisher and the clamping mechanism together, thus avoiding inaccurate measurement results.

[0004] In the above technical solutions, the accuracy of weighing and testing is ensured by clamping the fire extinguisher. Generally, the testing of fire extinguishers only involves observing the appearance and checking whether the pressure gauge is within the normal range, often neglecting the testing of the spray hose. If there are tiny holes in the hose wall, they are difficult to detect with the naked eye. If there is a leak in the spray hose, it will reduce the subsequent fire extinguishing efficiency, thus making the testing operation lack completeness. Therefore, a fire protection facility testing device based on fire protection engineering is proposed to solve the above problems. Utility Model Content

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 protection scope of the present utility model.

[0032] Reference Figures 1-3 This utility model provides an embodiment of a fire protection facility testing device based on fire protection engineering, comprising a cart 1, a water tank 2 fixedly connected to the top of the cart 1, the water tank 2 being used to store water for sealing testing of the fire extinguisher's spray hose, a water outlet pipe on one side of the water tank 2 for discharging the internal water source, an air pump 3 fixedly connected to the top of the cart 1, a telescopic pipe 4 fixedly connected to the output end of the air pump 3, a sealing sleeve 5 fixedly connected to the end of the telescopic pipe 4, an airbag ring 9 being provided inside the sealing sleeve 5, the outer surface of the airbag ring 9 being fixedly connected to the inner surface of the sealing sleeve 5, and the spray hose being inserted into the sealing sleeve 5. Contacting the airbag ring 9, the airbag ring 9 increases the sealing between the sealing sleeve 5 and the injection hose. The inner wall of the airbag ring 9 is fixedly connected to the inflation hose 10. The surface of the inflation hose 10 is provided with a one-way valve 11. The end of the inflation hose 10 is fixedly connected to a rigid ring 13. The rigid ring 13 increases the rigidity of the air inlet port of the inflation hose 10, making it easier to insert the air pump 12. The outer wall of the rigid ring 13 is provided with the air pump 12. The top of the trolley 1 is fixedly connected to the storage compartment 17. The inside of the storage compartment 17 is provided with a sealing ring 16. Several sets of sealing rings 16 are provided, which can be inserted into the tail end of the injection hose to seal it.

[0033] Reference Figures 2-4The air pump 12 has a positioning component on its surface, which includes a waterproof magnetic ring 14 and a waterproof magnetic ring 15. The side wall of the waterproof magnetic ring 14 is fixedly connected to the end of the rigid ring 13 away from the inflation hose 10. The outer wall of the waterproof magnetic ring 14 is magnetically connected to the waterproof magnetic ring 15. The inner surface of the waterproof magnetic ring 15 is fixedly connected to the outer surface of the air outlet tube of the air pump 12. Through the magnetic attraction between the waterproof magnetic ring 14 and the waterproof magnetic ring 15, the air pump 12 can be connected to the rigid ring 13, making it convenient for the operator to operate the air pump 12 with both hands. The top of the cart 1 is equipped with... An auxiliary testing component is provided, which includes an air compressor 6. The bottom of the air compressor 6 is fixedly connected to the top of the cart 1. A transmission pipe 7 is fixedly connected to the output end of the air compressor 6, and a threaded sleeve 8 is fixedly connected to the end of the transmission pipe 7. The threaded sleeve 8 can be adapted to the pressurization interface of the fire extinguisher valve. The pressure is slowly and gradually released through the air compressor 6. During the pressurization process, the reading of the pressure gauge on the air compressor 6 is closely observed. According to the type and specifications of the fire extinguisher, its pressure is increased to the specified test pressure value to observe whether the fire extinguisher has any abnormal phenomena such as leakage or deformation.

[0034] Reference Figure 5 The inner wall of water tank 2 has an annular groove 18, which is fitted onto the outer wall of the water outlet of water tank 2. The inner wall of water tank 2 has a T-shaped groove 19, and a fixing ring 20 is attached to the inner wall of water tank 2. A filter screen 21 is fixedly connected to the inner wall of the fixing ring 20. The filter screen 21 can filter the water inside water tank 2 when it is discharged, and ensure that impurities are temporarily retained in the water when the water is recycled into the fire protection system. A rubber ring 22 is fixedly connected to the side wall of the fixing ring 20. The inner wall of the annular groove 18 is adapted to the inner wall of the rubber ring 22. A T-shaped block 23 is fixedly connected to the outer wall of the rubber ring 22. The outer wall of the T-shaped block 23 is adapted to the inner wall of the T-shaped groove 19. By inserting the T-shaped block 23 into the T-shaped groove 19, and with the friction of the rubber ring 22 itself, the filter screen 21 can be quickly installed at the water outlet of water tank 2.

[0035] Working principle: When testing a fire extinguisher, the spray hose is removed from the extinguisher. Before testing, ensure that both ends of the spray hose are free of impurities. Insert the tail end of the spray hose into the matching sealing ring 16 for sealing, and insert the head end of the spray hose into the sealing sleeve 5. At this time, the air bladder ring 9 is fitted onto the head end of the spray hose. Manually insert the air outlet of the air pump 12 into the rigid ring 13. The magnetic attraction between the waterproof magnetic ring 14 and the waterproof magnetic ring 15 connects them. Air is injected into the inflation hose 10 through the air pump 12. The inflation hose 10 guides the air into the air bladder ring 9 to inflate it. The air bladder ring 9 gradually expands, squeezing the spray hose to reduce the gap between the two. After inflation is complete, apply force to the air pump 12 to... After detaching from the rigid ring 13, due to the one-way valve 11, air can only be injected through the opening of the inflation hose 10. The air inside the airbag ring 9 cannot overflow from the inflation hose 10, thus ensuring the seal between the spray hose and the sealing sleeve 5. Finally, air is injected into the telescopic tube 4 using the air pump 3. The air enters the spray hose through the sealing sleeve 5. The spray hose is then placed inside the water tank 2. At this time, the spray hose is underwater. Carefully check whether there are bubbles on the surface of the spray hose. If no bubbles are generated, it indicates that the spray hose is well sealed. If bubbles emerge, it indicates that there is a leakage problem in the spray hose. It is necessary to further check the location and cause of the leakage, or replace it in time to avoid affecting subsequent fire fighting.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
