Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, and in particular to an intelligent fire protection equipment testing and maintenance device. Background Technology

[0002] Currently, firefighters often face high-risk environments such as high temperatures and falling objects when performing firefighting and rescue missions. As one of their key protective equipment, fire helmets need to have good impact resistance. The intelligent fire equipment testing and maintenance device is mainly used for testing the impact resistance of fire helmets. Through high-precision sensors and other systems, it can monitor the stress state of the helmet in real time, assess its impact resistance, automatically determine whether the helmet has structural fatigue or hidden dangers, and upload the test results to the management platform through wireless communication to realize remote monitoring, early warning and maintenance reminders, ensuring the safety protection performance of firefighters in actual combat.

[0003] A Chinese patent has been published: a smart fire-fighting equipment testing and maintenance device, patent announcement number: CN213933434U. The patent "includes a base, two sets of first push motors are symmetrically installed on both sides of the upper surface of the base with the center line, the top of the two sets of first push motors are connected to a top plate, a second electric push rod is fixedly installed on the top of the top plate, the output end of the second electric push rod passes through the top plate and is fixedly connected to an electromagnet assembly, an adsorption component is provided at the bottom of the electromagnet assembly, a placement plate is provided below the adsorption component, and a skull replacement is fixedly provided on the upper surface of the placement plate."

[0004] Although the device uses a spring to compress a ring-shaped pressure sensor and then displays the test pressure of the fire helmet directly on the control unit, it is inconvenient to replace different sized adsorption components. This means that every time a different weight adsorption component is replaced, the operator must manually lift the insertion tube repeatedly, then operate the first electric push rod to move the electromagnet assembly downward and de-energize it. After that, the new adsorption component is placed on the placement tray, and the first electric push rod is operated repeatedly to move the electromagnet assembly upward and energize it to re-adsorb the adsorption component. The process is cumbersome and time-consuming, which not only increases the labor of the staff but also affects the testing efficiency. Utility Model Content

[0012] The beneficial effects of this utility model are:

[0013] 1.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0025] like Figures 1 to 5 As shown, an intelligent fire-fighting equipment inspection and maintenance device includes a base 1, a sliding rod frame 2 fixedly connected to the top of the base 1, a placement frame 3 for placing a fire helmet slidably connected between the outer walls of the sliding rod frame 2 to shield the broken pieces of the fire helmet, a pressure sensor 4 fixedly connected to the top of the base 1, a first spring 5 fixedly connected between the top of the pressure sensor 4 and the bottom of the placement frame 3, a first sliding plate 6 slidably connected between the outer walls of the sliding rod frame 2, a hollow cylinder 7 fixedly connected to the middle part of the first sliding plate 6, a gravity block 8 installed at the bottom of the hollow cylinder 7, and a replacement mechanism for replacing gravity blocks 8 of different weights provided on the outer wall of the hollow cylinder 7.

[0026] Further, see attached document. Figures 3 to 5As shown, the replacement mechanism includes a limiting bolt 9 that is slidably connected to the outer wall of the hollow cylinder 7. There are two limiting bolts 9. The ends of the two limiting bolts 9 that are far apart from each other are provided with a first through groove 10. Pressing rods 11 are rotatably connected to both sides of the outer wall of the hollow cylinder 7. The pressing rods 11 are V-shaped. The top of the pressing rods 11 extends into the first through groove 10. The bottom end of the pressing rods 11 is fixedly connected to a pressing block 12. A second spring 13 is fixedly connected between the pressing block 12 and the opposite side of the hollow cylinder 7. The top of the gravity block 8 is fixedly connected to a post 14. Limiting grooves 15 are provided on both sides of the post 14. One end of the limiting bolt 9 and the inner wall of the limiting groove 15 are adapted to each other.

[0027] When it is necessary to replace the gravity block 8, the operator first presses the pressing block 12 set on the outside of the device. Under the action of force, the pressing block 12 drives the pressing rod 11 connected to it to rotate, and at the same time compresses the second spring 13 set between the pressing block 12 and the hollow cylinder 7. Since the pressing rod 11 has a V-shaped structure, one end of it will produce a lifting effect during rotation and slide along the first through groove 10 opened at one end of the limiting bolt 9. During this sliding process, the top of the pressing rod 11 will push against the limiting bolt 9, thereby causing one end of the limiting bolt 9 to disengage from the originally embedded limiting groove 15, thereby releasing the limiting of the gravity block 8. After the limiting is released, the current gravity block 8 can be taken out and replaced with a gravity block 8 of different weights to meet the testing requirements of the fire helmet under different impact intensity conditions.

[0028] By incorporating a cooperating structure consisting of a pressing block 12, a pressing rod 11, a second spring 13, a limiting bolt 9, a first through groove 10, and a limiting groove 15, the operator only needs to press the pressing block 12 to automatically release the limiting bolt 9, thereby quickly disassembling or replacing the gravity block 8. This eliminates the need for frequently lifting the insertion tube or operating complex components such as electric push rods and electromagnet assemblies, significantly simplifying the operation process and reducing manual labor intensity. Furthermore, compared to existing structures that require multiple power cycles and replacements of the adsorption components, this replacement mechanism is stable and responsive, capable of replacing the gravity block 8 within seconds, greatly improving the efficiency of impact testing and demonstrating significant practical value and promising prospects for wider application.

[0029] Further, see attached document. Figure 2 and Figure 3As shown, a servo motor 16 is fixedly connected to the side wall of the base 1, and a threaded rod 17 is fixedly connected to the output end of the servo motor 16. The top end of the threaded rod 17 is rotatably connected to the top inner wall of the slide rod frame 2. A second slide plate 18 is threadedly connected to the outer wall of the threaded rod 17. The two ends of the second slide plate 18 are slidably connected to the outer wall of the slide rod frame 2. A second through groove 19 is provided in the middle part of the second slide plate 18. Two opposing clamping plates 20 are rotatably connected to the inner wall of the second through groove 19. An arc-shaped clamping block 21 is fixedly connected to the bottom end of each opposing clamping plate 20. A third spring 22 is fixedly connected between the opposing sides of the opposing clamping plates 20. A clamping groove 24 is provided on the top of the hollow cylinder 7. The arc-shaped clamping block 21 and the clamping groove 24 are compatible.

[0030] During the impact resistance test of the fire helmet, the operator first starts the servo motor 16. The servo motor 16 drives the threaded rod 17 to rotate. The threaded rod 17 drives the second sliding plate 18 mounted on it to move up and down along the outer wall of the sliding rod frame 2. When the second sliding plate 18 moves down to the predetermined position, the two arc-shaped clamping blocks 21 on it will contact the top of the hollow cylinder 7. Under the squeezing action of the conical surface at the top of the hollow cylinder 7, the two arc-shaped clamping blocks 21 open to both sides, thereby causing the two connected clamping plates 20 to rotate. The third spring 22, located between the clamping plates 20, is stretched. When the arc-shaped clamping block 21 descends to the same horizontal plane as the clamping groove 24, the third spring 22 retracts, causing the clamping plates 20 to automatically engage the arc-shaped clamping block 21 into the clamping groove 24, thus achieving stable clamping of the gravity block 8. Afterward, the servo motor 16 drives the threaded rod 17 to rotate in the reverse direction, causing the second sliding plate 18 to move upward. This, along with the arc-shaped clamping block 21, moves the gravity block 8 upward, simultaneously pulling the first sliding plate 6 connected to it upward. When the gravity block 8 rises to the set height, the... The compression column 23, positioned accordingly, presses against the tops of the two clamping plates 20, causing the clamping plates 20 to rotate and the arc-shaped clamping block 21 to disengage from the clamping groove 24, thus quickly releasing the gravity block 8. Under the influence of gravity, the gravity block 8 falls freely along with the first sliding plate 6 and impacts the fire helmet. During the impact, the fire helmet presses down on the placement frame 3 below, which further compresses the first spring 5 installed below it. After the first spring 5 contracts, it acts on the pressure sensor 4 installed below it. After detecting the corresponding impact pressure value, the pressure sensor 4 transmits the data to an external display device, enabling real-time monitoring and evaluation of the fire helmet's impact resistance performance. Compared with existing electric structures, this device replaces complex and expensive electric push rods and other structures with precise mechanical design, significantly reducing the cost of equipment and maintenance, while ensuring ease of operation and accuracy of test results. Through this structural optimization, not only is the complexity of manual operation reduced, but also the energy consumption and failure rate of the equipment are reduced, resulting in high practical value and economic benefits.

[0031] Further, see attached document. Figure 3As shown, two compression columns 23 are fixedly connected to the top of the inner wall of the slide bar frame 2. The tops of the two compression columns 23 and the two clamping plates 20 are on the same vertical line. The bottom ends of the two compression columns 23 are in contact with the top ends of the two clamping plates 20 respectively. The compression columns 23 will compress the clamping plates 20 when they rise to a certain height, and then the clamping plates 20 will rotate to release the restriction on the gravity block 8.

[0032] Further, see attached document. Figure 4 As shown, one end of the limiting bolt 9 has a ramp. When the insert 14 enters the hollow cylinder 7, it will squeeze the ramp at one end of the limiting bolt 9. Through the ramp at one end of the limiting bolt 9, when another gravity block 8 is installed, the insert 14 at the top of the gravity block 8 will squeeze the ramp, which makes it convenient for one end of the limiting bolt 9 to enter the limiting groove 15 to limit the gravity block 8.

[0033] Further, see attached document. Figure 4 As shown, the top of the hollow cylinder 7 is conical. When the hollow cylinder 7 rises, the top of the hollow cylinder 7 presses against the bottom of the arc-shaped clamping block 21. The conical shape of the top of the hollow cylinder 7 presses against the arc-shaped clamping block 21, thereby causing the clamping plate 20 to rotate and then enter the clamping groove 24 to limit the hollow cylinder 7.
