Description

Technical Field

[0001] The utility model relates to the technical field of puncture experimental devices, in particular to a precise puncture experimental device for perfluoromethylcyclohexanone silica gel pads. Background Art

[0002] Perfluoromethylcyclohexanone is an important alternative to halon fire extinguishers, with the following advantages: excellent environmental performance: its ozone depletion potential (ODP) is 0, and its global warming potential (GWP) is only 1. It has a short atmospheric lifetime and can permanently replace fire extinguishers that have an impact on the environment. High fire extinguishing efficiency: the fire extinguishing concentration for Class B fires is 4.5%. Excellent electrical insulation performance: it can pass the 110 kV test, ensuring fire extinguishing efficiency while meeting the requirements of use safety and environmental protection. The perfluoromethylcyclohexanone silica gel pad made by combining perfluoromethylcyclohexanone with silica gel is to utilize the characteristics of silica gel to endow the pad with certain elasticity, weather resistance, electrical insulation, etc., and at the same time, with the fire extinguishing performance of perfluoromethylcyclohexanone, to achieve the fire extinguishing or fire prevention function in specific scenarios. For example, in some equipment or places with high fire extinguishing requirements, the perfluoromethylcyclohexanone silica gel pad can play the roles of fire prevention, heat insulation, and fire extinguishing, or be used for sealing to prevent the spread of fire and smoke.

[0003] The silica gel pad puncture experimental device usually consists of the following main structural parts: Puncture mechanism: Puncture needle or probe: Usually made of high-strength and wear-resistant metal materials, and its shape and size are determined according to experimental requirements. Driving device: It can be electrically, pneumatically, or hydraulically driven, responsible for controlling the movement speed and force of the puncture needle. Fixing device: Sample stage: Used to place the silica gel pad sample to ensure its stability during the experiment. Clamp or fixture: Firmly fix the silica gel pad on the sample stage to prevent movement or deformation. Measuring system: Installed on the puncture needle or at a position connected to the puncture mechanism, used to measure the acting force during the puncture process and monitor the displacement of the puncture needle to obtain data such as puncture depth. Operation interface: Provided for the operator to input experimental parameters, start and stop the experiment, and view experimental data. Outer shell: Protect the internal mechanism and at the same time reduce the interference of the external environment on the experiment. Protective door or cover: Ensure safety during the experiment and prevent accidental injury to the operator.

When the air outlet pipe 25 in the air chamber 15 is pulled out, the puncture needle 17 moves to the limiting block 19 of the guiding tube 16 under the action of negative pressure. Subsequently, the telescopic cylinder 22 pushes the fixing pin 21 onto the limiting groove 26 on the puncture needle 17 to fix the puncture needle 17 in the guiding tube 16, and the infrared positioning lights 23 on the guiding tube 16 are used to determine the position of the puncture point.

[0033] Referring to Figures 1-4, a buffer seat 2 is fixedly connected to the bottom end of the puncture table 1, support legs 3 are fixedly connected to the four corners of the bottom end of the buffer seat 2, an operation keyboard 5 is arranged on the left side of the top end of the puncture table 1, a data display screen 4 is fixedly connected to the left middle side of the top end of the puncture table 1, connecting blocks 27 are fixedly connected to the left and right sides of the front and rear ends of the bottom of the sample seat 6, fixing rings 8 are fixedly connected to the front, rear, left and right ends of the sample seat 6, a sample clamping plate 7 is arranged on the top end of the sample seat 6, fixing rings 8 are fixedly connected to the front, rear, left and right ends of the sample clamping plate 7, and fixing bolts 9 are threadedly connected to the inner sides of the fixing rings 8.

[0034] Working principle: The tester places the silica gel pad on the sample seat 6. Subsequently, the silica gel pad is clamped on the sample seat 6 using the sample clamping plate 7. Then, the fixing rings 8 on the sample seat 6 and the sample clamping plate 7 are clamped and fixed to the silica gel pad through the fixing bolts 9 to prevent the silica gel pad from shifting during puncture. The tester connects the air inlet and outlet of the circulating air pump to the air inlet pipe 24 and the air outlet pipe 25 on the air cavity 15. Subsequently, the tester inserts the puncture needle 17 into the guiding tube 16. When the air outlet pipe 25 in the air cavity 15 is withdrawn, under the action of negative pressure, the puncture needle 17 moves to the limiting block 19 of the guiding tube 16. Subsequently, the telescopic cylinder 22 pushes the fixed pin 21 onto the limiting groove 26 on the puncture needle 17 to fix the puncture needle 17 in the guiding tube 16. Then, the tester controls the hydraulic rotating motor 11 through the servo controller 12 to adjust the angle of the puncture frame 13 according to the test requirements. At the same time, the infrared positioning lamp 23 on the guiding tube 16 is used to determine the position of the puncture point. Subsequently, compressed gas is pumped into the air inlet pipe 24 on the air cavity 15 through the circulating air pump. When the pressure in the air cavity 15 reaches an appropriate pressure, the telescopic cylinder 22 is controlled to retract the fixed pin 21. Under the push of air pressure, the puncture needle 17 punctures the silica gel pad. Subsequently, the puncture data is transmitted into the data display screen 4 for data analysis. The buffer fine sand filled in the buffer seat 2 prevents the puncture needle 17 from damaging the equipment and reduces the puncture impact force of the puncture needle 17.
