Description

Technical Field

[0001] This utility model relates to a detection instrument, and more particularly to a portable trace oxygen analyzer. Background Technology

[0002] In the power generation industry, the dissolved oxygen content in boiler feedwater has a significant impact on the safe operation and lifespan of boilers. Excessively high oxygen levels can lead to boiler pipe corrosion, affecting equipment lifespan and power generation efficiency. Therefore, the power industry has strict control standards for the trace oxygen content in boiler feedwater. Currently, trace oxygen analyzers are widely used. Because the test results place high demands on the equipment, the stability of the equipment during handling, storage, and use is crucial. Summary of the Invention

[0003] In order to overcome the above-mentioned defects of the prior art, this utility model aims to provide a portable trace oxygen analyzer that is easy to store, has a stable process, and thus improves detection accuracy.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A portable trace oxygen analyzer includes a housing and a main body located inside the housing for detecting trace oxygen concentration in water. The housing consists of an upper housing and a lower housing. The bottom plate of the lower housing has two parallel partitions, and the main body is located between the two partitions. The inner surfaces of the partitions and the surface of the bottom plate are recessed inward near the joint between them. An "L"-shaped locking plate is fixedly attached to the recess, and the horizontal plate of the locking plate is elastically connected to the bottom plate of the lower housing. The main body has inwardly recessed hooks on both sides and a pull ring on the top of the main body.

[0006] Preferably, the lower housing has a U-shaped cross-section, the upper housing has an inverted U-shaped cross-section, and the upper housing and the lower housing are snapped together after being inserted.

[0007] Preferably, the locking plate has a buffer structure on the side facing the body.

[0008] Preferably, both ends of the two partitions are fixedly connected by limiting plates.

[0009] Preferably, the lower housing is provided with a handle on its side.

[0010] Preferably, the bottom of the lower housing is provided with a support structure, and the support structure is provided with a suction cup on at least one side.

[0011] Preferably, the bottom plate of the lower housing has a grid-like heat dissipation window on the outside of the partition.

[0012] The housing of this invention provides a protective structure for the oxygen analyzer body, preventing most potential impacts during handling and transportation. The elastic compression of the locking plate further enhances protection. The snap-fit ​​connection of the housing facilitates opening and closing, making the oxygen analyzer extremely convenient to use. The support structure improves the overall stability of the device during daily storage and use. Attached Figure Description

[0016] The structure and principle of this utility model will now be fully explained with reference to specific embodiments, so that those skilled in the art can fully understand and implement it.

[0017] like Figure 1 , Figure 2 As shown, a portable trace oxygen analyzer includes a housing and a body 1 located inside the housing for detecting trace oxygen concentration in water. The housing consists of an upper housing 2 and a lower housing 3. The lower housing 3 has a U-shaped cross-section, and the upper housing 2 has an inverted U-shaped cross-section. The upper housing 2 and the lower housing 3 are interlocked and snapped together. Two parallel partitions 32 are provided on the bottom plate 31 of the lower housing 3, and the body 1 is located between the two partitions 32. The inner side of the partitions 32 and the surface of the bottom plate 31 are recessed inward near the joint between them. An L-shaped locking plate 4 is fixedly attached to the recess, and the horizontal plate of the locking plate 4 is elastically connected to the bottom plate 31. The two sides of the body 1 are provided with inwardly recessed hooks 11, and the top of the body 1 is provided with a pull ring 12.

[0018] In its normal state, the main body 1 is placed between the two partitions 32 of the lower housing 3. During placement, the horizontal plate of the locking plate 4 is pressed downwards, and the vertical plate of the locking plate 4 rotates inwards to press against the side wall of the main body 1, thus achieving a close and fixed fit of the main body 1. Further design features a buffer structure 41 on the side of the locking plate 4 facing the main body 1. This buffer structure 41 not only enhances the stability of the main body 1 but also protects it, reducing the impact of vibration and improving stability during daily storage and use.

[0019] Preferably, the front and rear ends of the two partitions 32 are fixedly connected by limiting plates 5. The two partitions 32 and the front and rear limiting plates 5 enhance the protection of the main body 1.

[0020] Preferably, the lower housing 3 is provided with a handle 33 on its side.

[0021] Preferably, the bottom of the lower housing 3 is provided with a support structure 6, and the support structure 6 has a suction cup 7 on at least one side. The design of the support structure 6 and the suction cup 7 further improves the stability of the device itself.

[0022] Preferably, the base plate 31 is provided with a grid-shaped heat dissipation window 34 on the outside of the partition plate 32.
