Description

Technical Field

[0001] The utility model belongs to the technical field of hydrogen quality detection, and in particular relates to an adjustable hydrogen quality detection device. Background Art

[0002] Hydrogen is a colorless, odorless, non-toxic, lightweight and flammable gas. Its molecular formula is H2, and it is one of the most abundant elements in the universe. Hydrogen gas has a low density and is about 14 times lighter than air. It has a very high combustion temperature and burning rate and is a high-energy fuel. Hydrogen is widely used in industry, medicine and energy fields. If the quality of hydrogen (purity, water content, pressure and temperature, etc.) does not meet the requirements, it may cause serious harm to the human body, the environment and equipment. Therefore, in order to ensure the purity and safety of hydrogen, a quality detection device is needed to detect the purity of hydrogen. Hydrogen quality detection devices include: hydrogen purity analyzer, hydrogen humidity detector, hydrogen leak detector, hydrogen pressure sensor, hydrogen flow meter, etc.

[0003] After searching, the announcement number CN220542879U discloses a hydrogen purity detection device, which includes a detection cylinder, a detection port and a switch; the detection port is arranged on the detection cylinder, and the detection port is used to connect and convey the hydrogen to be detected; the detection cylinder is divided into a detection chamber and a discharge chamber by the switch, and a detection sensor for detecting the purity of hydrogen is arranged in the detection chamber, and the discharge chamber is used to temporarily store hydrogen containing impurities; the switch is rotatably installed in the middle of the detection cylinder, and the switch switches the connection state of the detection port with the detection chamber or the discharge chamber by rotation; the device realizes the discharge of impurity gas in the conveying pipeline by using the detection chamber and the discharge chamber, thereby reducing the influence of impurity gas on the purity detection result; but when the device is used, there are still the following problems:

[0004] Since hydrogen molecules are very small molecules, they are easily adsorbed in the pipes in the detection device after detection. However, as disclosed above, hydrogen may still remain in the pipes in the detection device after being discharged only through the connection between the detection chamber and the discharge chamber, thereby affecting the accuracy of hydrogen quality detection and resulting in low detection accuracy.

[0005] Therefore, the utility model designs an adjustable hydrogen quality detection device to solve the problems raised in the above background technology. Utility Model Content

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.

[0035] Example 1: Please refer to Figure 1-4 The utility model provides a technical solution: an adjustable hydrogen quality detection device, comprising:

[0036] A detection box 1, wherein a purity sensor 2 is fixedly connected to the inner top wall of the detection box 1;

[0037] The exhaust mechanism 3, which is used to completely exhaust the hydrogen from the inner wall of the detection box 1, is arranged on the inner wall of the detection box 1, and includes a through frame 31 fixedly connected to both sides of the inner wall of the detection box 1, the inner wall of the through frame 31 is connected with an air suction hood 32, one end of the air suction hood 32 is connected with an exhaust pipe 33, the bottom end of the exhaust pipe 33 is connected with an exhaust fan 34, and an adsorption component 35 is arranged on the inner wall of the detection box 1, and the air suction hood 32 is in the shape of a trumpet.

[0038] It should be noted that the exhaust fan 34 and purity sensor 2 recorded above are relatively mature devices in existing technology applications. The specific models can be selected according to actual needs. At the same time, the exhaust fan 34 and purity sensor 2 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0039] When it is necessary to test the purity of hydrogen, the exhaust fan 34 is started, and the exhaust fan 34 extracts the hydrogen in the test box 1, so that the hydrogen is discharged through the suction hood 32 and the exhaust pipe 33, so that the hydrogen in the test box 1 can be quickly discharged, ensuring that there is no hydrogen residue in the test box 1, and the adjustment and treatment of the residual hydrogen in the test box 1 is simple; at this time, a new hydrogen sample is transported into the test box 1, and the hydrogen sample in the test box 1 is tested by the purity sensor 2, and the test data is displayed on the test box 1 for the inspection personnel to observe and record.

[0040] Example 2: Figure 2 As shown, the adsorption component 35 described in the design of this embodiment includes an adsorption plate 351 arranged on the inner wall of the through frame 31, and a rubber block 352 is fixedly connected to the top of the adsorption plate 351, and the surface of the rubber block 352 is slidably connected to the inner wall of the through frame 31 and the detection box 1; the adsorption plate 351 is made of a metal cluster material, and is used to adsorb hydrogen remaining in the detection box 1, thereby avoiding hydrogen remaining in the detection box 1.

[0041] Example 3: Figure 3-4 As shown, the inner wall of the through frame 31 described in the present embodiment is slidably connected with a blocking block 354, the front end of the blocking block 354 is fixedly connected with a connecting frame 355, the front end of the detection box 1 is slidably connected with a fixed block 358, the surface of the fixed block 358 is snapped onto the inner wall of the connecting frame 355, and the top of the fixed block 358 is fixedly connected with a spring 359, and the top end of the spring 359 is fixedly connected to the top of the detection box 1.

[0042] When in use, the fixing block 358 is pulled away from the connecting frame 355 to release the lock of the connecting frame 355, and the connecting frame 355 is pulled to move the two blocking blocks 354 at the same time to open the two through frames 31, so that the hydrogen in the detection box 1 can be discharged.

[0045] When the utility model is in use, the fixed block 358 is pulled to make the fixed block 358 away from the connecting frame 355, and the connecting frame 355 is pulled to make the two blocking blocks 354 move at the same time, thereby opening the two through frames 31, and starting the exhaust fan 34, the exhaust fan 34 extracts the hydrogen in the detection box 1, and the hydrogen is discharged through the suction hood 32 and the exhaust pipe 33, and the adsorption plate 351 begins to adsorb the hydrogen remaining in the detection box 1, thereby quickly discharging the hydrogen in the detection box 1, and the operation of adjusting and treating the residual hydrogen in the detection box 1 is simple, ensuring that there is no hydrogen residual in the detection box 1; then, the exhaust fan 34 is reversed to transport a new hydrogen sample into the detection box 1, and then the connecting frame 355 is pushed to make the blocking block 354 block the through frame 31, and the purity sensor 2 is used to start the detection of the hydrogen sample in the detection box 1, and the detection data is displayed on the detection box 1 for the observation and record of the detection personnel.
