DETAILED DESCRIPTION

[0020] 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 technical personnel in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 5 The utility model provides a technical solution: a special gas analysis sampling device, including a dustproof box 1, two hydraulic cylinders 2 are fixedly installed on the bottom wall of the inner wall of the dustproof box 1, the driving ends of the two hydraulic cylinders 2 are fixedly connected to the bottom of the battery box 3, a vacuum pump 4 is fixedly installed on the top of the battery box 3, a gas storage box 5 is fixedly connected to one side of the top of the vacuum pump 4, a sealing hose 6 is fixedly connected to the other side of the top of the vacuum pump 4, the top of the sealing hose 6 is sleeved with the bottom end of the sampling tube 7, a detection capillary 8 is provided on one side of the outer wall of the sampling tube 7, and a top cover 9 is provided on the top of the dustproof box 1.

[0022] In this embodiment, Figure 2 As shown, a battery 301 is installed inside the battery box 3; it should be noted that when the sampling device needs to be used to sample special gases, the operator can first open the top cover 9 and start the hydraulic cylinder 2 through an external controller to extend the driving end of the hydraulic cylinder 2 and drive the battery box 3 fixedly connected thereto to rise together. Because the vacuum pump 4 is fixedly connected to the top of the battery box 3, and the air inlet 401 of the vacuum pump 4 is also fixedly connected to the sampling tube 7, the sampling tube 7 will also rise during the entire process of the battery box 3 rising until it rises out of the outside of the dustproof box 1. At this time, the vacuum pump 4 is started by the external controller to extract special gases in the external environment through the sampling tube 7 to complete the gas sampling. During the operation of the above equipment, it can only be used with power supplied by the battery 301 installed inside the battery box 3, and the setting of the battery 301 can also ensure that sufficient power is provided for each device within a period of time, thereby maintaining the normal use of the entire sampling device.

[0023] In this embodiment, Figure 2 and Figure 5As shown, the vacuum pump 4 is composed of an air inlet 401 and an air outlet 402, and one end of a connecting pipe is fixedly connected to the top of the air outlet 402, and the other end of the connecting pipe is fixedly connected to one side of the air storage box 5; it should be noted that when it is necessary to use the entire sampling device to sample and detect special gases in the external environment, the operator can start the vacuum pump 4 in advance through an external controller, so that the vacuum pump 4 can extract the impurity air in the sampling tube 7 fixedly connected to the top air inlet 401, and then transport the impurity air to the air storage box 5 on one side through the air outlet 402. At this time, the sampling tube 7 is in a The vacuum state is achieved, thereby ensuring the purity of the gas during the sampling process. Then, the hydraulic cylinder 2 is started through an external controller to push and raise the sampling tube 7 located directly above it until the sampling tube 7 rises out of the dustproof box 1. At the same time, the air valve at the top of the sampling tube 7 is opened and the vacuum pump 4 is started again to draw the special gas in the air into the sampling tube 7 to complete the gas sampling. During this process, the air inlet 401 and the sampling tube 7 are connected together by a sleeved sealing hose 6, and the sealing hose 6 can ensure the airtightness between the sampling tube 7 and the air inlet 401 to prevent gas leakage accidents during the sampling process.

[0024] In this embodiment, Figure 3 and Figure 4 As shown, the air outlet end of the detection capillary 8 is fixedly connected with a filter box 801, and a filter element is placed inside the filter box 801; it should be noted that after the sampling tube 7 is extended out of the dustproof box 1 by the hydraulic cylinder 2, the vacuum pump 4 can be started to draw the special gas in the external air into the sampling tube 7. After completing the basic gas sampling, the valve installed on the top of the sampling tube 7 is closed to prevent the gas from leaking out. Then, in order to ensure that the sampled special gas will not be contaminated by other impurity air when the sampling tube 7 is removed for detection, a filter element is fixedly connected to the outer wall of one side of the sampling tube 7. The detection capillary 8 allows the special gas in the tube to be directly transported to the detection equipment for analysis through the detection capillary 8 after the sampling tube 7 takes a sample of the special gas, without going through the sample transport process, thereby better maintaining the original state of the gas in the sampling tube 7. A filter box 801 is also provided at the air outlet end of the detection capillary 8, and a filter element is also placed inside the filter box 801. Therefore, when the special gas in the sampling tube 7 is transmitted along the detection capillary 8 to the detection equipment, it can be filtered by the filter element, thereby ensuring that the impurity air is completely excluded, thereby not affecting the detection result.

[0025] In this embodiment, Figure 1 and Figure 2As shown, ultraviolet sterilization lamps 101 are fixedly installed on the inner walls of the front and rear sides of the dust box 1; it should be noted that after completing the sampling and detection of the special gas, the operator can start the hydraulic cylinder 2 again through the external controller, so that the driving end of the hydraulic cylinder 2 begins to shorten until the sampling tube 7 is completely retracted into the dust box 1. At this time, the top cover 9 can be covered on the top of the dust box 1, so that the dust box 1 forms a closed space. Because there are many types of special gases, including harmful gases, and each gas sampling process will more or less leave some gas attached to the surface of the sampling device. Therefore, the operator can start the ultraviolet sterilization lamp 101 through the external controller, and the ultraviolet lamp tubes are all lit up, and the light shines on the surface of the equipment. The ultraviolet disinfection and sterilization function can be used to eliminate all bacteria remaining on the surface of the equipment, thereby ensuring the cleanliness of the device. At the same time, the top cover 9 covering the top of the dust box 1 can effectively prevent external dust from falling into the box and accumulating on the sampling tube 7, vacuum pump 4 and other equipment, thereby affecting the normal use of the equipment.

[0026] In this embodiment, Figure 3 As shown, valves are fixedly installed at the top of the sampling tube 7 and the end of the detection capillary 8 away from the sampling tube 7. It should be noted that before using the sampling tube 7 for gas sampling, the operator needs to start the vacuum pump 4 to extract the impurity air inside the sampling tube 7 so that the sampling tube 7 is in a vacuum state, thereby ensuring that there is no impurity gas inside the sampling tube 7 to affect the sampling. In order to achieve the above purpose, when the sampling tube 7 is not in use, the valve installed at the top is always in a closed state, which can effectively prevent external gas from entering the sampling tube 7 from the opening of the sampling tube 7, thereby causing pollution to the gas in the tube. When the sampling tube 7 needs to be used for sampling, the valve can be opened again. Open, and absorb the external special gas into the interior of the sampling tube 7 through the vacuum pump 4. After completing the gas sampling in one place, the valve can be closed again to ensure that the gas will not leak out. At this time, the detection tube 8 is connected to the detection equipment, and the valve installed on the tube body of the detection tube 8 is opened. At this time, the special gas sample stored in the sampling tube 7 will flow to the detection tube 8. After the impurities are filtered by the filter box 801 at the air outlet end of the detection tube 8, the gas sample will be directly transported to the detection equipment and the result analysis will be completed. In this process, the special gas in the sampling tube 7 will not have any chance of being invaded by external gas, thereby ensuring the purity of the gas sample to the greatest extent.

[0027] The use method and advantages of the utility model: When the special gas analysis sampling device is used, the working process is as follows:

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4and Figure 5 As shown, before using the sampling tube 7 for gas sampling, the operator needs to start the vacuum pump 4 to extract the impurity air inside the sampling tube 7 so that the sampling tube 7 is in a vacuum state, and then start the hydraulic cylinder 2 through the external controller to extend the driving end of the hydraulic cylinder 2 and push the sampling tube 7 to completely rise out of the dustproof box 1. At this time, open the valve installed on the top of the sampling tube 7, and start the vacuum pump 4 to draw the special gas in the external environment into the sampling tube 7. After completing the gas sampling, close the valve, open the valve on the detection capillary 8, and connect the detection capillary 8 to the detection equipment at the same time. The special gas sample stored in the sampling tube 7 will flow to the detection tube 8. After passing through the impurities filtered by the filter element inside the filter box 801, the gas sample will be directly transported to the detection equipment for result analysis. After completing the sampling and detection of the special gas, the operator can start the hydraulic cylinder 2 again through the external controller, thereby driving the sampling tube 7 to descend until the sampling tube 7 is completely retracted into the dustproof box 1, and the top cover 9 is covered on the top of the dustproof box 1. At the same time, the ultraviolet sterilization lamp 101 is started to disinfect and sterilize the sampling device, and all bacteria remaining on the surface of the equipment are eliminated, thereby ensuring the cleanliness of the device.
