Description

Technical Field

[0001] The utility model relates to a fire extinguisher foam collection technology, in particular to a fire extinguisher foam collection sampling device. Background Art

[0002] Fire extinguisher foam is an extinguishing agent used to extinguish liquid fires. It is usually made of a mixture of water and a foaming agent, which causes the water to form foam, thereby increasing the surface area, reducing the surface tension of the water, and improving the fire extinguishing effect. Fire extinguisher foam can effectively extinguish liquid fires, such as flammable liquid fires such as oils, paints, and alcohols, because the foam can cover the surface of the liquid and prevent oxygen from coming into contact with the fire source, thereby extinguishing the flames. Foam samples are collected for quality control testing to ensure that the performance meets standards and specifications, including testing of parameters such as expansion rate, drainage time, and heat resistance. Foam samples are tested to verify their suitability for specific application scenarios. Different types of foam extinguishing agents may have different effects on different fires. Chemical composition analysis helps to ensure that the formulation meets the requirements and will not cause harm to the environment or personnel. Sampling analysis can help find the cause of fire extinguishing equipment failure.

[0003] The main components of the traditional fire extinguisher foam sampling device include sampling bottles, foam extinguishing agent samples, labels and sealing caps. The sampling bottle is usually a sealed container for holding foam samples, and its design can ensure that the sample is not contaminated or disturbed by the outside world. The foam extinguishing agent sample is the main body of the sampling and needs to be accurately collected for subsequent testing and analysis. The label is usually used to record sample information, including sampling time, location and other relevant information for traceability and identification. Finally, the sealing cap is used to seal the sampling bottle to prevent the foam sample from leaking or being affected by the outside world, ensuring the accuracy and reliability of sampling.

[0004] Traditional fire extinguisher foam sampling devices usually rely on operators to collect foam directly using handheld containers. However, this method has some disadvantages. The operator's skills and experience may lead to irregular and incorrect collection, which in turn affects the quality of the sample. In addition, manual collection is prone to introducing external impurities, which may cause sample contamination. These factors may affect the accuracy and quality of the foam sample, which in turn affects subsequent analysis and testing. Utility Model Content

[0027] Specifically, when using the fire extinguisher foam collection sampling device, first, the motor 30 inside the shell 1 is used, and the output end of the motor 30 drives the fan blade 29 to rotate to generate negative pressure, thereby generating suction. Subsequently, through the combination of the telescopic tube 2 and the suction nozzle 3, efficient collection of the foam is achieved. The collected foam then passes through the hole opened inside the shell 1 and enters the inclined surface opened inside the tank body 5. Next, the fixed column 26 is driven to rotate by the output end of the motor 7, and the rotation of the fixed column 26 drives the spiral blade 25 fixed on the outer wall to rotate together. In this process, the rotation of the fixed column 26 causes the foam to randomly drop into the inside of the material port 9, thereby achieving effective sampling of the fire extinguisher foam.

[0028] Reference Figure 2 , Figure 3 and Figure 6The tank body 5 is provided with a feed port 9 at the bottom, the tank body 5 is provided with a support plate 10, the top of the support plate 10 is fixedly connected with the feed port 9, the bottom of the support plate 10 is fixedly connected with a loading bucket 11, the bottom of the support plate 10 is fixedly connected with an elastic cylinder 12, the bottom of the elastic cylinder 12 is fixedly connected with a special-shaped column 22, the inside of the special-shaped column 22 is fixedly connected with a support column 2 14, the outer wall of the support column 2 14 is slidably connected with a fixing ring 21, one side of the fixing ring 21 is fixedly connected with a connecting plate 15, the top of the base 8 is fixedly connected with a hydraulic cylinder 19, and the output end of the hydraulic cylinder 19 is fixedly connected There is a connecting plate 15, a gear 20 is rotatably connected to the bottom of the supporting column 14, a motor 18 is fixedly connected to the top of the base 8, a gear 16 is fixedly connected to the output end of the motor 18, a rotating plate 17 is provided on the outer wall of the gear 16, and the gear 20 is meshed with the rotating plate 17, a connecting tube 31 is fixedly connected to the bottom of the loading barrel 11, a fixed block 32 is fixedly connected to the outer wall of the connecting tube 31, a connecting collar 24 is rotatably connected inside the fixed block 32, a connecting collar 24 is fixedly connected to a connecting block 23 on one side, and a sealing cover 13 is fixedly connected to one side of the connecting block 23;

[0029] Specifically, the foam is introduced into the loading barrel 11 through the feed port 9. Then, the output end of the motor 2 18 drives the gear 16 to rotate. Since the teeth on the surface of the gear 16 are not completely covered, the gear 2 20 will pause for a period of time after rotating one circle. Subsequently, the gear 2 20 drives the support column 2 14 to rotate, and then drives the special-shaped column 22 fixed on the top to rotate. Since the special-shaped column 22 is designed with a defective plane, this causes the fixed block 32 fixed by the connecting tube 31 to start moving. The connecting collar 24 in the fixed block 32 is driven to rotate by the defective design of the special-shaped column 22, and the connecting collar 24 fixes the connecting block 23. Finally, the sealing cover 13 fixed on one side of the connecting block 23 realizes the discharge control of the foam in the loading barrel 11. When adjusting the internal volume of the loading barrel 11, the output end of the hydraulic cylinder 19 drives the connecting plate 15 to move, and then moves the support column 2 14. In this process, the special-shaped column 22 is lifted up, realizing the precise control of the foam capacity.

[0030] Working principle: When the fire extinguisher foam collection sampling device is used, first, the motor 30 inside the shell 1 is used, and the output end of the motor 30 drives the fan blade 29 to rotate to generate negative pressure and generate suction, and then the foam is collected through the combination of the telescopic tube 2 and the suction nozzle 3, and then the collected foam is brought to the inclined surface opened inside the tank body 5 through the hole opened inside the shell 1, and the fixed column 26 is driven to rotate by the output end of the motor 17, and then the spiral blade 25 fixed on the outer wall is driven to rotate by the rotation of the fixed column 26. Due to the rotation of the spiral blade 25 driven by the fixed column 26, the foam is randomly dropped into the inside of the material port 9, thereby achieving the effect of sampling the fire extinguisher foam, and then the foam falls into the inside of the loading bucket 11 through the material inlet 9, and then the gear 16 is driven to rotate by the output end of the motor 2 18. Since the teeth on the outer surface of the gear 16 are not completely covered on its outer surface, due to the incompleteness of the gear 16, Instead, the gear 20 will rotate one circle and then stop for a period of time, and then the support column 2 14 will be driven to rotate through the gear 20, and then the special-shaped column 22 fixed on the top of the support column 2 14 will be driven to rotate together. Since one end of the special-shaped column 22 is designed as a defective plane design, the fixed block 32 fixed to the outer wall of the connecting tube 31 is driven to move. Due to the defective design of the special-shaped column 22, the connecting ring 24 inside the fixed block 32 is driven to rotate, and the connecting ring 24 plays the role of a fixed connecting block 23, and then the sealing cover 13 fixed on one side of the connecting block 23 is used to discharge the foam inside the loading barrel 11. When the internal volume of the loading barrel 11 is adjusted, the output end of the hydraulic cylinder 19 is used to drive the outer wall of the fixing ring 21 fixed to one side of the connecting plate 15 to move the outer wall of the support column 2 14, and then the special-shaped column 22 is lifted up by the movement of the support column 2 14, thereby achieving the effect of controlling the foam capacity.
