Description

Technical Field

[0001] This utility model belongs to the field of fire protection equipment technology, and in particular relates to a fire protection equipment tester. Background Technology

[0002] Firefighting equipment refers to various facilities and equipment used to prevent and respond to fires. It mainly includes manual alarm buttons, fire hydrants, fire extinguishers, and smoke detectors. Before being used by the factory, smoke detectors need to be tested by the fire equipment testing device. Only those that meet the performance standards are allowed to be used.

[0003] A search revealed a fire equipment testing device disclosed in patent publication number CN220877613U. The device includes a testing platform with casters at each of the four corners of its lower surface. Fixed blocks are fixedly installed at both ends of the testing platform, with a stabilizing plate detachably installed at one end of each fixed block. Adjustment components are located at each of the four corners of the upper surface of the testing platform. A circular hole is formed at the center of the upper surface of the testing platform, and a combustion chamber is detachably installed within this hole. The casters at the four corners of the lower surface facilitate movement of the testing platform by personnel, allowing for faster movement to the designated location and improving convenience during testing. The fixed blocks at both ends, along with the stabilizing plate detachably installed at one end of each fixed block, enhance the overall stability of the testing platform during use. The adjustment components at the four corners of the upper surface allow for adjustment of the height of the smoke detectors according to the testing requirements.

[0004] The aforementioned fire equipment testing device has a circular hole at one center end of the inner surface of its testing platform. A combustion bowl is detachably installed inside the hole, allowing personnel to place burning materials into the combustion bowl for combustion testing. Placing materials in the combustion bowl helps prevent the fire from spreading; however, it is inconvenient to extinguish the flames inside the combustion bowl in a timely manner, posing a safety hazard and reducing the safety of testing smoke detectors. Furthermore, the testing platform has adjustment components at each of its four corners. Each adjustment component includes a corner plate, which is fixedly installed at one corner of the testing platform. Each corner plate has a sliding groove at one end, and multiple sliding blocks are slidably installed within these grooves. The other end of each sliding block is fixedly connected to a connecting plate. The smoke detector is located at one center end of the lower surface of the connecting plate. A sliding groove is provided at one end of the corner plate, allowing a sliding block to slide within the groove. A connecting plate is fixedly mounted at one end of the sliding block, enabling the connecting plate to be easily raised for height adjustment. This allows the smoke detector mounted on one end of the lower surface of the connecting plate to follow the adjustment, thereby improving detection accuracy. A hydraulic rod is provided at one end of the inner wall of the sliding groove, with the other end of the hydraulic rod fixedly connected to one end of the sliding block. This allows for easy up-and-down adjustment of the sliding block, improving practicality. However, when the height of the smoke detector is increased, the distance between the smoke detector and the smoke outlet increases, causing smoke leakage and reducing the contact between the smoke detector and the smoke, which will affect the testing effect of the smoke detector.

[0005] To address these issues, we provide a fire equipment testing instrument. Utility Model Content

[0036] Specifically, the combustion box 202 is located inside the limiting frame 103. The bolt 103a is threadedly connected to the side wall of the combustion box 202, and the combustion box 202 is located on the upper surface of the base plate 1.

The guide assembly 3 includes a top plate 301, a smoke detector 301a, a hydraulic cylinder 302, a hydraulic rod 302a, a hollow shaft 303, a movable shaft 303a, a lower U-shaped plate 304, a bracket 304a, a telescopic tube 305, an upper U-shaped plate 306, and a connecting seat 306a. The smoke detector 301a detects the smoke generated when the combustible material inside the combustion box 202 is burned, thus enabling the testing of the smoke detector 301a. Furthermore, by controlling the hydraulic cylinder 302, the hydraulic rod 302a extends or retracts, and the telescopic tube 305 extends or retracts, the distance between the smoke detector 301a and the combustion box 202 is adjusted. The distance between the lower ring plate 304 and the combustion box 202 remains unchanged, and the distance between the upper ring plate 306 and the smoke detector 301a remains unchanged. This avoids an increase in smoke leakage caused by an excessively large distance between the lower ring plate 304 and the combustion box 202, and allows sufficient smoke to move upward, thereby improving the testing effect of the smoke detector 301a.

[0041] Specifically, the top plate 301 is positioned above the combustion chamber 202. The lower end of the hydraulic cylinder 302 is connected to the upper surface of the base plate 1, and the upper end of the hydraulic cylinder 302 is connected to a hydraulic rod 302a. The upper end of the hydraulic rod 302a is connected to the lower surface of the top plate 301. The lower end of the hollow shaft 303 is connected to the upper surface of the base plate 1, and a movable shaft 303a is sleeved inside the hollow shaft 303. The upper end of the movable shaft 303a is connected to the lower surface of the top plate 301, and the middle part of the lower surface of the top plate 301 is connected to... A smoke detector 301a is connected to the upper ring plate 306 located below the top plate 301. A connecting seat 306a is connected to the upper surface of the upper ring plate 306. The upper surface of the connecting seat 306a is connected to the lower surface of the top plate 301. A telescopic tube 305 is connected to the lower surface of the upper ring plate 306. A lower ring plate 304 is connected to the lower surface of the telescopic tube 305. A bracket 304a is connected to the outer side wall of the lower ring plate 304.

The four supports 304a are arranged in a rectangular array, and the four connecting seats 306a are arranged in a rectangular array.

[0043] The operation process of this embodiment is as follows: the combustible material inside the combustion box 202 is ignited, and the smoke moves upward through the lower circular plate 304, the telescopic tube 305, and the upper circular plate 306. The smoke detector 301a detects the smoke. When the hydraulic cylinder 302 is activated and the hydraulic rod 302a extends, the movable shaft 303a moves upward, the top plate 301 moves upward, the upper circular plate 306 moves upward, and the telescopic tube 305 extends. The distance between the lower circular plate 304 and the combustion box 202 remains unchanged, and the distance between the upper circular plate 306 and the smoke detector 301a remains unchanged. This allows more smoke to move upward through the lower circular plate 304, the telescopic tube 305, and the upper circular plate 306, which is beneficial to improving the testing effect of the smoke detector 301a.
