[0003] Existing detection devices generally simulate heavy objects hitting fire helmets, such as a fire equipment detection device disclosed in Chinese Patent Publication No. CN216791927U, or a fire equipment detection device disclosed in Chinese Patent Publication No. CN217716857U, including a base and a positioning block arranged on the base, a head mold is placed on the positioning block, a support plate is arranged on the base corresponding to the positioning block, a top plate is arranged on the support plate, two guide columns are arranged at the bottom of the top plate, a slider is slidably arranged on the two guide columns, a downward pressure head is arranged on the slider, a counterweight mechanism is arranged on the slider, a connecting rope is arranged on the slider, two limit assemblies are arranged on the top plate corresponding to the connecting rope, a baffle is arranged on the side of the support plate, a handle is arranged on the end of the connecting rope through the baffle, and the handle can be pulled and then released to move the downward pressure head and collide with the helmet.
[0004] Among the above-mentioned testing equipment, the trajectory of the heavy object in the first test is difficult to predict, and it is easy to bounce and splash after hitting the helmet, which is not safe enough.

[0024] 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.
[0025] A fire fighting equipment detection device, such as Figure 1-Figure 3As shown, it includes a base plate 1, one end of the base plate 1 is fixedly installed with a head mold 2 for carrying a fire helmet, and the other end of the base plate 1 is provided with a detection device for testing the strength of the fire helmet. Specifically, the detection device includes two groups of columns 3 set up on opposite sides, a central shaft 4 is fixedly installed between the two groups of columns 3, and the central shaft 4 is a long circular rod. A striking rod 5 that can rotate around the axis of the central shaft 4 is movably installed on the central shaft 4, and a striking head 6 is detachably fixedly installed at the end of the striking rod 5 away from the central shaft 4. The rotation trajectory of the striking head 6 around the central shaft 4 is staggered with the head mold 2. During the detection, by The striking head 6 rotates to a suitable position above the central rotating shaft 4. During the process of the striking head 6 rotating to the top of the central rotating shaft 4, the potential energy is continuously increased due to gravity or other components. After reaching the suitable position, the potential energy accumulated by the striking head 6 is released, thereby generating kinetic energy to hit the fire helmet on the head mold 2 to test the fire helmet. During the test, the striking head 6 is always fixedly connected to the base plate 1 through the striking rod 5 and the central rotating shaft 4, and will not deviate from the predetermined track, which is predictable. At the same time, the potential energy accumulated by the rotation of the striking head 6 can be controlled by the rotation angle of the striking rod 5, which is convenient for adjusting the test intensity.
[0026] In other embodiments, in order to increase the potential energy of the striking rod 5, a rear plate 7 is fixedly installed between the two groups of columns 3, and a pressure spring 8 is fixedly installed between the rear plate 7 and the striking rod 5. During the upward rotation of the striking rod 5, the pressure spring 8 is compressed to generate elastic potential energy, thereby further increasing the adjustment range of the test intensity.
[0027] In other embodiments, there are multiple fixed positions between the two ends of the pressure spring 8 and the striking rod 5 and the rear plate 7, so that a group of pressure springs 8 can generate different elastic potential energies when the striking rod 5 rotates by the same angle, making it easier to adjust the test intensity.
[0028] Furthermore, in order to facilitate the automated control of the rotation angle of the striking rod 5, electric telescopic rods 9 are fixedly installed on the two groups of columns 3, and a gripper 10 is fixedly installed on the output end of the electric telescopic rod 9. The gripper 10 clamps a card rod 11, and the card rod 11 is located below the striking rod 5. Specifically, the electric telescopic rod 9 is installed inverted on the column 3, that is, the gripper 10 is located below the electric telescopic rod 9, so that after the gripper 10 is released and the card rod 11 is clamped, the striking rod 5 can be immediately smashed down. After the smashing is completed, the gripper 10 clamps the card rod 11 again, and then the electric telescopic rod 9 contracts, so that the card rod 11 lifts the striking rod 5 from bottom to top, completing a round of testing.
[0029] In a preferred embodiment, the two ends of the clamping rod 11 are movably connected with a rotating sleeve 12, and the rotating sleeve 12 can rotate around the clamping rod 11. The gripper 10 is clamped on the rotating sleeve 12 to reduce the friction between the clamping rod 11 and the gripper 10, and reduce the power consumption caused by the friction when the clamping rod 11 lifts the striking rod 5.
[0030] In other embodiments, in order to prevent the clamping rod 11 from being separated from the striking rod 5 after the gripper 10 releases the clamping rod 11, a connecting block 13 that can rotate around the clamping rod 11 is movably installed in the middle of the clamping rod 11, and a limiting groove 14 is provided on the connecting block 13. The limiting groove 14 is sleeved on the striking rod 5, so that the clamping rod 11 is connected to the striking rod 5.
[0031] Furthermore, the width of the limiting groove 14 is the same as the width of the striking rod 5, so that the connecting block 13 and the clamping rod 11 will not swing left and right. The length of the limiting groove 14 is 1.5 times the thickness of the striking rod 5, so that the connecting block 13 can have a certain range of motion with the striking rod 5, and the friction force is smaller during the process of lifting the striking rod 5.
[0032] The working principle of the utility model is as follows: during the detection, the striking head 6 is rotated to a suitable position above the central rotating shaft 4. During the process of the striking head 6 rotating to the top of the central rotating shaft 4, the potential energy is continuously increased due to gravity or other components. After reaching the suitable position, the potential energy accumulated by the striking head 6 is released, thereby generating kinetic energy to hit the fire helmet on the head mold 2 to test the fire helmet. During the test, the striking head 6 is always fixedly connected to the base plate 1 through the striking rod 5 and the central rotating shaft 4 and will not deviate from the predetermined track, which is predictable. At the same time, the potential energy accumulated by the rotation of the striking head 6 can be controlled by the rotation angle of the striking rod 5, so as to facilitate the adjustment of the test intensity.
[0033] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
