Description

Technical Field

[0001] This utility model relates to the field of sensor technology, and specifically provides a gas leak detection device. Background Technology

[0002] Gas leak detection equipment, such as mass spectrometer leak detectors, is a device that determines whether a leak exists and the size of the leak by applying a specific tracer gas to the target and detecting whether the gas enters the target through a potential leak point.

[0003] To improve portability, most existing gas leak detection devices modularize and integrate their components into a housing. However, this single-housing structure makes it difficult to observe the internal modules, and the integrated design results in a relatively compact layout with insufficient space for disassembly. Therefore, there is an urgent need for a gas leak detection device that facilitates the inspection and replacement of the internal modules. Utility Model Content

[0004] This invention provides a gas leak detection device to solve the problems of inconvenient internal parts inspection and disassembly and poor heat dissipation in existing portable small-volume gas leak detection devices.

[0005] The technical solution of this utility model is as follows:

[0006] A gas leak detection device includes an outer shell and an internal module. The outer shell includes an upper cover and a lower basket bottom that are adapted to each other. The upper cover and the lower basket bottom are detachably connected. The internal module is detachably connected to the lower basket bottom. The left and right sides of the lower basket bottom are provided with notches. The upper cover has right-angled plates on both sides that are adapted to the notches.

[0007] This design divides the outer shell into two detachable parts, allowing the upper cover to be opened quickly and easily for rapid internal observation, heat dissipation, and cleaning. The detachable internal modules also facilitate their inspection and replacement. Furthermore, the notches on both sides of the lower basket bottom expose the internal modules when the upper cover is opened, providing ample space for maintenance personnel to apply force from the sides to disassemble the internal modules first. This continuously provides space for subsequent disassembly, effectively avoiding the problems of insufficient disassembly space and damage to internal modules found in existing technologies.

[0008] Preferably, the lower basket has heat dissipation meshes on its left, right and / or rear sides, and a fan is installed at the heat dissipation meshes.

[0009] In this design, a heat dissipation mesh and a fan are installed on at least one of the four sides of the bottom of the casing to facilitate the dissipation of heat from inside the casing. Preferably, heat dissipation meshes are installed on the left, right, and rear sides, with one fan for intake and the other two for exhaust, achieving a dual airflow system that can effectively dissipate heat from inside the casing.

[0010] Preferably, the front side of the lower basket bottom is tilted upwards. The front side is used to install a multi-functional display panel. Tilting the front side upwards conforms to the human viewing angle, allowing the multi-functional display panel on the front side to be directly in line with the inspector's line of sight, preventing glare, and facilitating clear observation of the display on the multi-functional display panel by the inspector.

[0011] Preferably, a chamfered surface is provided at the connection between the front side of the lower basket and the bottom surface, and an indicator light strip is provided in the chamfered surface. The indicator light strip can light up different colors according to the detection status of the equipment.

[0012] In this solution, an indicator light strip is installed on the chamfered surface, which avoids interference between the indicator light strip and the bottom surface of the lower basket. Furthermore, the indicator light strip can emit different colors of light, with each color corresponding to a different detection status, allowing inspectors to more intuitively judge whether the target is leaking. This optimizes the equipment observation method and also improves the aesthetics of the device.

[0013] Existing miniaturized portable gas leak detection devices frequently collide with other equipment during transport or operation, making their outer casing extremely vulnerable to damage. Furthermore, the casing is a unibody structure, requiring complete replacement for repairs, resulting in very high costs. Therefore, the support plate is a U-shaped structure, with detachable legs at its bottom, and the lower basket is secured within the support plate. The legs allow for a gap at the bottom when the device is placed on a flat surface, providing some heat dissipation and moisture protection.

[0014] The "U"-shaped support plate section can protect the sides and four corners of the outer shell, preventing damage to these more vulnerable parts of the outer shell.

[0015] Meanwhile, since the internal modules are detachably connected by long bolts, that is, bolts are inserted from the bottom of the outer shell, and corresponding bolt holes are set on the internal modules to realize the detachable connection of the internal modules, the support plate covers the bottom of the lower basket, which can effectively prevent the bolts from rusting.

[0016] Furthermore, in existing technologies, in some cases the equipment lacks a platform large enough to accommodate all the outriggers, causing the device to tilt during placement. In such cases, the outriggers that can fit on the platform need to be disassembled to ensure stable placement. While the outriggers are typically bolted to the bottom of the equipment, the thin outer shell necessitates nuts inside the shell to reinforce the bolted connections. However, these nuts are prone to slipping off during outrigger disassembly, potentially damaging internal components. This new solution addresses this by placing the outriggers independently on a support plate. This support plate, with its inherent thickness, eliminates the need for nuts for secure connection. The threaded holes on the support plate allow for connection, avoiding the problems encountered in existing technologies.

[0017] Preferably, the bottom surface of the support plate extends beyond the bottom of the lower basket in the orientation of the front and rear sides of the lower basket bottom. The support plate extending beyond the bottom of the lower basket bottom can cover the four corners of the lower basket bottom, thereby protecting the four corners of the lower bottom and the sides of the lower bottom surface of the lower basket bottom.

[0018] Preferably, the support plate includes a front support plate near the front side and a rear support plate near the rear side, with the vertical side plates of the front support plate connected to the left and right side walls of the lower basket bottom. When no support legs are provided, the support plate acts as the support for the equipment, with wear concentrated on the bottom surface of the support plate. The support plate also protects the four corners and sides of the outer casing. Dividing the support plate into two parts facilitates disassembly and replacement as needed, thereby reducing maintenance costs.

[0019] Preferably, the vertical side plate of the rear support plate is connected to the left and right side walls of the lower basket bottom by bolts and nuts, and the rear support plate can rotate around the line connecting the connection point with the left and right side walls.

[0020] By rotating the rear support plate, the overall angle of the device can be adjusted to adapt the device to a surface with a certain slope.

[0021] Preferably, the lower basket bottom is provided with foam around the outer surface of the opening. In this solution, since the components in the internal module will vibrate during operation, the detachable design of the outer shell may cause collisions between the upper shell cover and the lower basket bottom. By providing foam, the vibration can be reduced, and the gap between the upper shell cover and the opening of the lower basket bottom can also be eliminated.

[0022] Preferably, the internal module includes a pump unit, a vacuum gauge unit, and a solenoid valve unit. The pump unit and vacuum gauge unit are located near the front side of the lower basket bottom, and the solenoid valve unit is located near the rear side of the lower basket bottom. A buffer layer is provided on the inner surface of the U-shaped front support plate. The vibration of the device is mainly generated by the pump unit. An additional shock-absorbing buffer layer is provided at the bottom of the pump unit to directly reduce vibration at the source, effectively reducing the overall amplitude of the device. The light emitted by the indicator light bar shines on the inner surface of the front support plate and is scattered. Because the indicator light bar is located on the downward-sloping chamfered surface, when the equipment is placed in an open and low position, the operator may not be able to see the color of the indicator light bar clearly. After the light from the indicator light bar hits the inner surface of the front support plate, it is scattered, making the light emitted by the indicator light bar more obvious.

[0023] The beneficial effects of this utility model are:

[0024] 1. The outer shell of this utility model is divided into two detachable parts, which can be opened quickly and easily to facilitate observation, heat dissipation and cleaning. At the same time, the detachable internal modules are more conducive to the inspection and replacement of the internal modules. When the upper shell is opened, the internal modules on both sides can be exposed through the low side formed by the notches on both sides of the bottom of the lower basket. This gives maintenance personnel enough space to apply force from the side to disassemble the internal modules on both sides first, providing space for subsequent disassembly. This effectively avoids the problems of disassembly difficulties and damage to internal modules caused by insufficient disassembly space in the prior art.

[0025] 2. This utility model is equipped with a support plate, which facilitates the installation of the support legs and effectively protects the sides and bottom of the outer shell, preventing damage to the device body and thus affecting the detection effect. Attached Figure Description

Detailed Implementation

[0032] The technical solution of the present invention will be clearly and completely described in conjunction with the accompanying drawings and through specific implementation methods of the embodiments of the present invention.

[0033] Example 1:

[0034] like Figure 1 and Figure 2 A gas leak detection device is shown, comprising an outer shell 1, an internal module 2, and a support plate 3 supporting the outer shell 1. The internal module 2 is detachably connected to the bottom surface of the outer shell 1. The outer shell 1 is divided into an upper shell cover 11 and a lower basket bottom 12 that fit together. The upper shell cover 11 and the lower basket bottom 12 are detachably connected. The left and right sides of the lower basket bottom 12 have notches, the height of which is lower than the height of the front and rear sides of the lower basket bottom 12. The upper shell cover 11 has right-angled curved plates on both sides that fit the notches. The upper shell cover 11 and the lower basket bottom 12 combine to form a relatively enclosed box.

[0035] The outer shell 1 is divided into two detachable parts, which can be opened quickly and easily to facilitate observation, heat dissipation and cleaning. At the same time, the detachable design of the internal module 2 makes it easier to inspect and replace the internal module 2. Furthermore, because the lower basket bottom 12 is lower on both sides, when the upper shell 11 is opened, more of the internal module 2 can be exposed through the low sides of the lower basket bottom, and there is also enough operating space to disassemble the internal modules 2 on both sides first.

[0036] Furthermore, foam 16 is provided around the outer surface of the opening of the lower basket bottom 12. Since the components in the internal module 2 will vibrate during operation, the detachable design of the outer shell 1 may cause collisions at the mating point of the upper shell cover 11 and the lower basket bottom 12. By providing foam 16, the vibration can be reduced, and the gap between the upper shell cover 11 and the opening of the lower basket bottom 12 can also be eliminated.

[0037] Furthermore, a heat dissipation grid 13 is provided on the left side, right side and / or rear side of the lower basket bottom 12, and a fan 24 is provided at the heat dissipation grid 13.

[0038] Specifically, by providing a heat dissipation grid 13 and a fan 24 on at least one of the three sides of the bottom of the lower basket 12, heat dissipation from the inside of the outer casing 1 is facilitated. Preferably, heat dissipation grids 13 are provided on the left, right, and rear sides, and it is possible to have one fan 24 for air intake and two fans 24 for air exhaust; two fans 24 for air exhaust and one fan 24 for air intake; all three fans 24 for air intake; and all three fans 24 for air exhaust, etc. It should be noted that if a low-power leak detection device is used, only one fan 24 needs to be configured at one heat dissipation grid 13 for air exhaust; fans 24 are not needed at the other heat dissipation grids 13. Using one fan 24 for air exhaust creates a negative pressure inside the device, allowing the other heat dissipation grids 13 to draw in air, forming an airflow channel inside the device to facilitate heat dissipation. In this embodiment, it is preferred that one fan 24 is used for air intake and the other two fans 24 are used for air exhaust, achieving a dual airflow channel, enhancing convection, and effectively dissipating heat from the outer casing 1.

[0039] Furthermore, the front side of the lower basket bottom 12 is tilted upwards. This front side is used to house the multi-functional display panel 17. Tilting the front side upwards conforms to the human viewing angle, ensuring the multi-functional display panel 17 is directly facing the inspector's line of sight, preventing glare, and facilitating clear observation of the display. A chamfered surface 14 is provided at the junction of the front side and the bottom surface of the lower basket bottom 12. An indicator light bar 15 is installed within this chamfered surface 14, and the indicator light bar 15 illuminates in different colors according to the equipment's detection status.

[0040] Specifically, an indicator light strip 15 is installed on the chamfered surface 14 to avoid interference between the indicator light strip 15 and the bottom surface of the lower basket 12. Simultaneously, the indicator light strip 15 is electrically connected to the control panel inside the device, allowing it to emit different colors of light. Each color corresponds to a different detection status; for example, the indicator light strip 15 displays yellow during detection, red after a leak is detected, and green when no leak is detected at the end of the detection. This allows inspectors to more intuitively determine whether the target is leaking, optimizing the observation method and improving the aesthetics of the device.

[0041] Example 2:

[0042] Based on Embodiment 1, in order to further protect the outer casing 1 and the internal module 2, such as Figure 2 and Figure 3 As shown, the support plate 3 has a U-shaped structure, and a detachable support leg 31 is provided at the bottom of the support plate 3. The lower basket bottom 12 is fastened into the support plate 3. The support leg 31 allows for a certain gap at the bottom when the equipment is placed on a flat surface, which plays a certain role in heat dissipation and moisture prevention.

[0043] It should be noted that in existing technologies, in some cases the equipment does not have a platform large enough to accommodate all the support legs 31, causing the device to tilt during placement. In such cases, the support legs 31 that can be placed on the platform need to be disassembled to ensure stable placement. While the support legs 31 are typically bolted to the bottom of the equipment, the thinness of the outer shell 1 necessitates the use of nuts inside the shell 1 to enhance the stability of the bolted connection. However, these nuts are prone to loosening during disassembly, potentially damaging internal components. In this solution, the support legs 31 are individually mounted on the support plate 3. The support plate 3 has sufficient thickness, allowing the support legs 31 to be securely connected without nuts, or the nuts can be directly placed on the inner surface of the support plate 3, avoiding the problems encountered in existing technologies. Furthermore, the U-shaped support plate 3 provides protection for the sides and corners of the outer shell 1, preventing damage to these vulnerable areas.

[0044] Furthermore, since the internal module 2 is detachably connected by long bolts, that is, bolts are inserted from the bottom of the outer shell 1, and corresponding bolt holes are provided on the internal module 2 to realize the detachable connection of the internal module, the support plate 3 covers the bottom of the lower basket 12, which can effectively prevent the bolts from rusting.

[0045] Furthermore, the bottom surface of the support plate 3 extends beyond the front and rear sides of the lower basket bottom 12. The support plate 3 extending beyond the lower basket bottom 12 can cover the four corners of the lower basket bottom 12, thereby protecting the four corners of the lower bottom and the sides of the lower bottom surface of the lower basket bottom 12.

[0046] Furthermore, the support plate 3 includes a front support plate 32 near the front side and a rear support plate 33 near the rear side. The vertical side plates of the front support plate 32 are connected to the left and right side walls of the lower basket bottom 12. When the support legs 31 are not provided, the support plate 3 replaces the support legs 31 to support the equipment. Wear is concentrated on the bottom surface of the support plate 3, while the support plate 3 also protects the four corners and sides of the outer casing 1. Dividing the support plate 3 into two parts facilitates disassembly as needed during maintenance and replacement, thereby reducing maintenance costs.

[0047] In this embodiment, the vertical side plate of the rear support plate 33 is connected to the left and right side walls of the lower basket bottom 12 by bolts and nuts. The rear support plate 33 can rotate around the line connecting its connection point with the left and right side walls. By rotating the rear support plate 33, the overall angle of the device can be adjusted to adapt the device to a placement surface with a certain slope.

[0048] More specifically, the internal module 2 includes a pump unit 21, a vacuum gauge unit 22, and a solenoid valve unit 23. The pump unit 21 and vacuum gauge unit 22 are located near the front side of the lower basket bottom 12, while the solenoid valve unit is located at the rear of the lower basket bottom 12, facilitating wiring and reducing wiring difficulty. Furthermore, a buffer layer 34 can be provided on the U-shaped inner surface of the front support plate 32. The buffer layer 34 can be made of materials such as foam 16 or rubber, and the inner surface of the front support plate 32 is in close contact with the bottom surface of the lower basket bottom 12. Since the vibration of the device is mainly generated by the pump unit 21, which is located near the front side of the lower basket bottom 12, and the front support plate 32 is positioned directly below the pump unit 21, the additional shock-absorbing buffer layer at the bottom of the pump unit 21 directly dampens the vibration at the source, effectively reducing the overall vibration amplitude of the device.

[0049] Furthermore, in Embodiment 1, the light emitted by the indicator light strip 15 illuminates the inner surface of the front support plate 32 and is scattered. Since the indicator light strip 15 is located on the downward-sloping chamfered surface 14, when the equipment is placed in an open and low position, the operator may not be able to see the color of the indicator light strip 15 clearly. The light from the indicator light strip 15 is scattered on the inner surface of the front support plate 32, making the light emitted by the indicator light strip 15 more obvious.

[0050] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
