Description

Technical Field

[0001] This invention relates to the field of detection technology, and more specifically to a protection device for a detection component. Background Technology

[0002] A glove box is a sealed device that provides an anhydrous, oxygen-free, or clean environment, widely used in fields sensitive to water and oxygen, such as lithium battery research and development, materials synthesis, and chemical experiments. To ensure the internal environment meets standards, glove boxes are typically equipped with water and oxygen sensors to monitor water and oxygen content in real time. During normal operation, the water and oxygen sensors are constantly exposed to the internal atmosphere. When the glove box requires sample transfer, internal wall cleaning, or leaks leading to increased water and oxygen levels, the sensor probe surface is susceptible to corrosion from water vapor, oxygen, and organic solvent vapors, resulting in performance degradation, slower response, or even failure. This shortens the sensor's lifespan and increases equipment maintenance costs. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention provides a detection component protection device that separates the environment inside the glove box from the detection component when detection is not required, thereby protecting the detection component.

[0004] Specifically, this invention discloses a protection device for a detection component, comprising: The detection components are located on the outside of the sealed enclosure; An isolation and protection component is installed on the sealed enclosure to isolate the detection component from the internal environment of the sealed enclosure when detection is not required.

[0005] The advantages of this invention are that by placing the detection component on the outside of the sealed enclosure and using an isolation protection component, the detection end does not need to be exposed to the internal environment of the sealed enclosure for a long time. When detection is not required, the isolation protection component can block the contact between the detection component and the internal environment of the sealed enclosure, preventing the detection component from being exposed to water, oxygen or corrosive atmosphere for a long time and causing performance degradation, thus extending the service life of the detection component and reducing the maintenance cost of the equipment. At the same time, the structural design is simple, the modification is easy, it is compatible with existing sealed enclosure equipment, and it does not occupy additional working space inside the enclosure.

[0006] Furthermore, the sealed housing has a through hole, and the detection end of the detection component is located inside the through hole.

[0007] The advantage of adopting the above technical solution is that by reserving the detection end of the detection component at the through hole, it can be ensured that the detection end can directly contact the atmosphere inside the chamber to obtain accurate detection results when detection is required, and it is not necessary to extend the entire detection component into the chamber, which facilitates subsequent isolation operation and daily maintenance of the detection component.

[0008] Furthermore, the isolation and protection component includes: a mounting plate, a sealing head, and a driving component. The sealing head is mounted on the mounting plate, the driving component drives the mounting plate to move, and the sealing head covers the detection end of the detection component.

[0009] The advantage of adopting the above technical solution is that by driving the mounting plate to move through the driving component, the sealing head can be driven to complete the sealing and opening of the detection end. The operation is simple and convenient, and it can quickly realize the isolation protection of the detection component and the switching of the detection state. The isolation effect is stable and reliable.

[0010] Furthermore, the detection component is connected to the sealed box via a connecting block. The connecting block is provided with an air inlet and an air outlet. The air outlet is connected to an air outlet pipe that communicates with the inside of the sealed box. The air outlet pipe is provided with a one-way valve. Inert gas is introduced through the air inlet.

[0011] The advantages of adopting the above technical solution are that after the inert gas is introduced, the inert gas can enter the connecting block from the air inlet and then be discharged into the sealed box through the air outlet in one direction. This can form an inert gas purging on the detection end side, cleaning up the impurities and corrosive gases attached to the detection end. At the same time, after the sealing head covers the detection end, the inert gas can maintain the detection end in a low-impurity inert atmosphere, further improving the protection effect on the detection component. The one-way valve can also prevent the atmosphere inside the sealed box from flowing back into the connecting block, ensuring the protection effect.

[0012] Furthermore, an extension tube is installed on the outside of the sealed housing. Both ends of the extension tube are connected to the sealed housing and are equipped with valves. The detection component is installed on the extension tube, and its detection end extends into the interior of the extension tube.

[0013] The advantage of adopting the above technical solution is that the extension tube can be isolated from the inside of the sealed box by two valves, and the detection end can be isolated from the environment inside the box without moving the detection component. The structure is simple and the operation is convenient. The detection component is fixedly set on the extension tube. During detection, it is only necessary to open the valves on both sides to connect the environment inside the extension tube at both ends with the environment inside the valves.

[0014] Furthermore, the extension tube is provided with a first air port and a second air port. When the detection stops, inert gas is introduced into the first air port and the inert gas flows out from the second air port.

[0015] The advantage of adopting the above technical solution is that after stopping the detection and closing the valves on both sides, inert gas is introduced into the extension tube through the first gas port, which can replace the original gas containing impurities and corrosive components in the extension tube, so that the detection end is always in a pure inert atmosphere, further improving the protection effect and extending the service life of the detection component.

[0016] Furthermore, the sealed box is provided with an installation box, and a movable plate is provided inside the installation box. The detection component is located on the movable plate. The sealed box is provided with a detection hole corresponding to the detection end of the detection component, and a sealing block is provided on the outside of the detection hole.

[0017] The advantage of adopting the above technical solution is that when testing is required, the moving plate drives the testing component through the testing hole to enter the sealed box for testing. When testing is not required, the moving plate drives the testing component back to the mounting box, and the sealing block moves to block the testing hole, which can completely separate the testing component from the environment inside the box. The switching between testing and protection states is smooth, the isolation is thorough, and the protection effect is good.

[0018] Furthermore, a guide plate is provided on the inner side of the sealed box, and the mounting plate moves along the guide plate.

[0019] The advantage of adopting the above technical solution is that the guide plate can limit and guide the movement path of the mounting plate, avoid positional deviation during the movement of the mounting plate, ensure that the sealing head can be accurately aligned with the detection end of the detection component, improve the accuracy and reliability of sealing and isolation, and make the isolation protection effect more stable.

[0020] Furthermore, the mounting plate is provided with a through hole, and the sealing head is provided with a hole communicating with the through hole, and a one-way valve is connected to the through hole.

[0021] The advantage of adopting the above technical solution is that the one-way valve can prevent the gas in the box from flowing back in, thus ensuring the protection effect continuously.

[0022] Furthermore, a sealing ring is installed on the contact surface between the sealing head and the sealing housing.

[0023] The advantage of adopting the above technical solution is that the sealing ring can fill the gap between the sealing head and the sealing box, improve the sealing performance, prevent the atmosphere inside the box from leaking to the detection end position from the gap, further ensure the isolation and protection effect, and prevent corrosive gases from contacting the detection components.

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings.

[0028] like Figure 1 As shown, the present invention discloses a protection device for a detection component, comprising: The detection component 1 is located on the outside of the sealed enclosure 2. The detection component 1 includes: a water analyzer, an oxygen analyzer or other detection instruments, sensors, etc. An isolation and protection component is installed on the sealed enclosure 2 to isolate the detection component 1 from the internal environment of the sealed enclosure 2 when detection is not required.

[0029] The advantages of this invention are that by placing the detection component 1 on the outside of the sealed housing 2, and in conjunction with the isolation protection component, the detection end does not need to be exposed to the internal environment of the sealed housing 2 for a long time. When detection is not required, the isolation protection component can block the contact between the detection component 1 and the internal environment of the sealed housing 2, avoiding the performance degradation of the detection component 1 due to long-term exposure to water, oxygen or corrosive atmosphere, extending the service life of the detection component 1, reducing the maintenance cost of the equipment, and at the same time, the structural design is simple, the modification difficulty is low, it is compatible with existing sealed housing 2 equipment, and does not occupy additional working space inside the housing.

[0030] In some implementation schemes, such as Figure 2-3 The sealed housing 2 has a through hole, and the detection end of the detection component 1 is located in the through hole, so that the detection end of the detection component 1 comes into contact with the environment inside the housing and performs detection inside the housing.

[0031] Furthermore, the isolation and protection assembly includes: a mounting plate 4, a sealing head 41, and a driving component 42. The sealing head 41 is mounted on the mounting plate 4, and the driving component 42 is a cylinder fixed in the sealing box to drive the mounting plate 4 to move. The mounting plate 4 is located inside the sealing box. The sealing head 41 covers the detection end of the detection assembly 1. The number of sealing heads 41 is the same as the number of detection ends. If the detection end is a protruding cylinder, the sealing head 41 is provided with a cylindrical groove to cover the detection end and play a sealing role.

[0032] Furthermore, the detection component 1 is connected to the sealed housing 2 via a connecting block 43. The connecting block 43 is provided with a cavity to accommodate the detection end of the detection component 1 and the sealing element. The connecting block 43 is provided with an air inlet 44 and an air outlet 45, which are connected to the cavity. The air outlet 45 is connected to an air outlet pipe 46 that is connected to the inside of the sealed housing. A one-way valve is provided on the air outlet pipe 46. After the detection is completed, as the sealing head enters the cavity, inert gas is introduced through the air inlet 44 to purge the environment inside the cavity. The gas is discharged into the sealed housing 2 through the air outlet pipe 46. The sealing head extends into the connecting block 43 to complete the seal. The purging ensures that there are no other impurities or corrosive gases between the detection end and the sealing element, thus extending the service life of the detection component 1.

[0033] Furthermore, a guide plate 47 is provided on the inner side of the sealing box. The mounting plate 4 moves along the guide plate 47. A guide rail and a slider are installed on the guide plate 47. The slider is connected to the mounting plate 4 to guide the mounting plate 4 and ensure the position of the sealing head 41.

[0034] In some implementation schemes, such as Figure 4 As shown, an extension pipe 5 is installed on the outside of the sealed box 2. Both ends of the extension pipe 5 are connected to the sealed box 2 and are equipped with valves, such as ball valves, gate valves, bellows sealing valves, etc. The detection component 1 is installed on the extension pipe 5, and its detection end extends into the interior of the extension pipe 5. A fan 53 is installed inside one end of the extension pipe 5. When detection is required, the fan 53 is started to allow the gas inside the box to circulate with the gas inside the extension pipe 5. At this time, the detection component 1 detects the environment inside the sealed box to ensure the detection effect.

[0035] Furthermore, the extension tube 5 is provided with a first air port 51 and a second air port 52. When the detection stops, inert gas is introduced into the first air port 51 and the inert gas flows out from the second air port 52. The second air port 52 can be connected to the sealed housing 2 to replace the gas in the extension tube 5, so that the detection component 1 is in a clean environment when not in use, which protects the detection end.

[0036] In some implementation schemes, such as Figure 5-6As shown, the sealed housing is equipped with a mounting box 6, inside which is a movable plate 61. The detection component 1 is mounted on the movable plate 61, which is connected to a cylinder drive. The sealed housing has a detection hole corresponding to the detection end of the detection component 1. A movable sealing block 62 is provided on the outside of the detection hole. The sealing block 62 is fan-shaped and is mounted on the outside of the sealed housing 2 via a rotating shaft 63. The rotating shaft 63 is rotatably mounted on the outside of the housing and has a gear mounted on its upper end, which is connected to a motor through gear transmission. The sealing block 62 has a through hole corresponding to the detection hole, which can be used when needed. During testing, the motor drives the sealing block 62 to rotate, aligning the through hole on the sealing block 62 with the detection hole on the sealing housing 2. The detection end enters the detection hole for testing. After testing, the motor drives the sealing block 62 to rotate, causing the through hole on the sealing block 62 to be misaligned with the detection hole. The sealing block 62 blocks the detection hole, achieving a sealing function. At the same time, the mounting box 6 is also equipped with an air inlet 44 and an air outlet 45. When not in use, the mounting box 6 is purged with clean gas to replace the residual gas inside the box, ensuring that the detection component 1 is always in a clean, inert atmosphere, further enhancing the protection effect.

[0037] In some implementation schemes, such as Figure 7 As shown, the mounting plate 4 is provided with a through hole, and the sealing head is provided with a hole communicating with the through hole. The through hole is connected to a one-way valve. This configuration does not require an additional vent pipe 46. As the sealing block 62 moves toward the detection component 1, the gas inside the sealing block 62 is discharged through the one-way valve, effectively reducing the internal gas residue and achieving the sealing effect.

[0038] In some implementations, a sealing ring 3 is installed on the contact surface between the sealing head 31 and the sealing housing.

[0039] The advantages of this invention are: simple overall structure, easy modification, direct compatibility with existing sealed enclosures such as glove boxes, no major modifications to the internal structure of the enclosure are required, and no occupation of the working space inside the enclosure; the isolation and protection components can quickly isolate the detection component 1 from the corrosive atmosphere inside the sealed enclosure 2 when detection is not required, and can also be used in conjunction with inert gas purging and replacement to replace the residual corrosive gas around the detection component 1 with clean inert gas, significantly reducing the probability of the detection component 1 being corroded and failing, effectively extending the service life of the detection component 1, reducing the frequency and cost of equipment maintenance, convenient operation for switching between detection and protection states, low difficulty in automation modification, and compatibility with glove boxes and other equipment with special environmental requirements.

[0040] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this invention, and these all fall within the protection scope of this invention.
