Technical Field

[0001] The utility model belongs to the field of glove box gas detection, and specifically relates to a glove box gas probe detection platform. Background Art

[0002] At present, the detection method of gas probe detection is basically to connect to the glove box, and use nitrogen or nitrogen oxygen, nitrogen helium, argon, krypton and other large amounts of gas to replace the glove box atmosphere to detect the measurement status of the gas probe.

[0003] During the process of replacing the box atmosphere, due to the large internal volume of the glove box, more gas needs to be introduced to replace the original gas inside. The entire replacement process takes too long and is costly. In addition, during the process of introducing gas into the glove box, there is no control over the gas flow rate, making it impossible to accurately determine whether the gas inside the entire box is exhausted, which may lead to errors in the data of the gas detection probe.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] like Figures 1 to 4As shown, a glove box gas probe detection platform described in the utility model comprises a barrel body 1, having an air inlet 3 and an exhaust port 4, wherein the exhaust port 4 is a unidirectional conductive setting;

[0033] One end of the air inlet path is connected to the outside, and the other end is connected to a flow controller 6 , and the flow controller 6 is connected to the air inlet 3 .

[0034] In the utility model, the barrel body 1 of the test barrel is generally a cylindrical structure, and the bottom of the barrel body 1 is fixedly connected with four support angles 12 or a complete support plate, and the four corners of the support plate are protruding from the bottom of the barrel body 1. The four protruding corners are equipped with feet 2, and at least the bottom of the feet 2 is provided with rubber pads, so as to enhance the shock absorbing effect of the feet 2 and avoid damage to some sensitive gas sensors; it can also ensure the horizontal calibration of the test bench to meet the test requirements of some sensors.

[0035] In addition, the barrel body 1 is provided with an air inlet 3 and an air outlet 4 for connecting the inside with the outside, wherein the air outlet can only be directed in one direction, that is, the gas can only flow from the inside of the barrel body 1 to the outside. A flow controller 6 is planned to be provided on the barrel body 1, wherein the flow controller 6 can be an MFC gas flow controller or a float flow meter. The air inlet end of the flow controller 6 is connected to the outside, and the air outlet end thereof is connected to the air inlet 3 on the barrel body 1.

[0036] The specific implementation method is: according to the volume of the barrel body 1, the test gas is accurately introduced into the barrel body 1 by using the flow controller 6, and the introduced test gas then enters the inner cavity of the barrel body 1 through the air inlet 3. The test gas continuously squeezes the original atmosphere in the barrel and continuously replaces the gas in the test barrel. The replaced waste gas is continuously discharged through the exhaust port 4 until it is exhausted. This design directly transfers the original detection platform in the glove box to the barrel body 1 of this design. The test air flow rate can be accurately controlled by the flow controller 6. In a short time, less gas can be introduced to perform the stable and effective detection function of the gas probe, providing an atmosphere environment for the normal and accurate detection of the gas probe detection function.

[0037] Furthermore, the air inlet 3 and the air outlet 4 are arranged on the same end surface of the barrel body 1 .

[0038] In the utility model, the air inlet 3 and the exhaust port 4 in the barrel body 1 can be respectively arranged on different end surfaces of the barrel body 1, and the combination thereof is varied. However, in order to facilitate observation and control of the overall ventilation and exhaust, the air inlet 3 and the exhaust port 4 are arranged at the upper end of the barrel body 1. In addition, multiple exhaust ports 4 can be arranged to connect the exhaust gas pipeline of the workshop and conveniently discharge the exhaust gas from the workshop.

[0039] Furthermore, a one-way valve 41 is provided in the exhaust port 4, and its conducting direction is from the inside of the barrel body 1 to the outside.

[0040] In the utility model, a one-way valve 41 is provided in the exhaust port 4, so as to control the reflux of the gas during exhaust, and ensure that the gas in the barrel body 1 can be gradually discharged until it is completely exhausted during the replacement process.

[0041] Furthermore, it also includes:

[0042] At least one sensor interface 5 is disposed at the top of the barrel body 1 and is used for installing a sensor.

[0043] In the utility model, a plurality of sensor interfaces 5 are also provided at the top of the barrel body 1, and the sensor interfaces 5 can adapt to various sensors used in various glove boxes. Specifically, the sensor interfaces 5 are detachable, so that they can be replaced according to the interface models of different sensors. Through the design of multiple sensor interfaces 5, the detection functions of various gas sensors can be detected, making the detection platform of the barrel body 1 more universal.

[0044] Furthermore, a barrel cover 11 adapted to the barrel mouth is sealedly connected to the barrel body 1, and a plurality of reinforcing ribs 8 are arranged in an array around the barrel mouth side wall of the barrel body 1.

[0045] In the utility model, the mouth of the barrel body 1 is closed by a detachable barrel cover 11. The barrel mouth of the barrel body 1 has a flange 13 structure, and the flange 13 extends outward perpendicularly to the side wall of the barrel body 1. A sealing notch is provided on the flange 13 of the barrel body 1, and the notch is in the shape of a dovetail groove. Through the setting of the sealing notch, the sealing effect after the barrel cover 11 is connected to the barrel body 1 can be ensured, and the outside air or the gas inside the barrel body 1 can be prevented from overflowing here, which affects the control effect of gas delivery and the effect of gas probe detection.

[0046] In addition, in order to ensure that the flange 13 of the barrel body 1 will not be deformed, a plurality of reinforcing ribs 8 are provided on the flange 13 of the barrel body 1 and the outer wall of the barrel body 1. The reinforcing ribs 8 are L-shaped, so that the flange 13 of the barrel body 1 can be effectively supported to ensure its verticality. The plurality of reinforcing ribs 8 are arranged in an annular array along the outer periphery of the barrel body 1, and then fixed by a locking nut 7, so that the sealing performance of the barrel body 1 can be ensured.

[0047] Furthermore, the barrel body 1 includes an upper barrel body 101, a lower barrel body 103 and a connecting barrel body 102, and the upper barrel body 101 and / or the lower barrel body 103 are sealed and slidably connected to the connecting barrel body 102 to change the height of the entire barrel body 1.

[0048] In the present utility model, reference Figure 4, the barrel body 1 can be set to be at least telescopic up and down, so that the height of the entire barrel body 1 can be adjusted. Specifically, the barrel body 1 has a connecting barrel body 102, and the outer periphery of the connecting barrel body 102 has at least one slide groove that is sealed and slidably connected to the upper barrel body 101 and / or the lower barrel body 103, that is, the upper barrel body 101 and the lower barrel body 103 are sealed and slidably sleeved on the connecting barrel body 102. By moving the upper barrel body 101 or the lower barrel body 103, and by tightening the bolts, the state of the telescopic barrel body 1 is maintained. Since the height of the barrel body 1 can be adjusted up and down, it can be applied to the detection of more gas sensors.

[0049] For example, the helium sensor has a relatively long measuring part, and needs a higher test barrel 1 to meet the basic requirements of its installation and testing. The barrel 1 in this design can be telescopically adjusted to adjust its overall height, so that the helium sensor can be easily installed. Similarly, combined with the above-mentioned implementation steps of inputting gas, the atmosphere in the test area of ​​the barrel 1 can be effectively replaced with a small amount of gas in a short time, and then the detection function of the helium sensor can be judged.

[0050] The above is only a preferred embodiment of the present invention, and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes using the above-mentioned technical contents without departing from the scope of the technical solution of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the present invention.
