Technical Field

The utility model relates to an air monitoring technology field specifically is ammonia nitrogen on-line monitoring appearance.

Background

The ammonia nitrogen refers to nitrogen existing in the form of free ammonia and ammonium ions in water, the nitrogen content of animal organic matters is generally higher than that of plant organic matters, and meanwhile, nitrogen-containing organic matters in human and animal feces are unstable and are easy to decompose into ammonia, so the ammonia nitrogen in water is combined ammonia existing in the form of ammonia or ammonium ions when the content of the ammonia nitrogen in water is increased.

The sampling head of the existing portable ammonia nitrogen online monitor is directly exposed outside, the monitor is separated from the hand and falls off in the operation process of workers, the sampling head is easy to damage, the sampling head lacks of dustproof measures, dust is easily adsorbed on the surface, and therefore the ammonia nitrogen online monitor with a protection structure is required to be convenient to use.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an ammonia nitrogen on-line monitoring appearance to solve the monitor and fall the problem of easy damage.

In order to achieve the above object, the utility model provides a following technical scheme: ammonia nitrogen on-line monitoring appearance, which comprises a housin, install the display screen on the casing, install the protection post on the casing, the sampling head is installed to the inboard of protection post, protects the sampling head through the protection post, and the sampling head ground connection causes the damage when avoiding dropping, the last symmetric welding of protection post has the spliced pole, the upper end of spliced pole is fixed with the shrouding.

Preferably, the protection post is provided with sealed frame in a sliding manner, sealed frame sliding connection is on the surface of spliced pole, and the air inlet is opened along spliced pole and protection post downstream to sealed frame, and the sampling head can detect the air.

Preferably, the protection post is sleeved with a spring, two ends of the spring are respectively connected with the sealing frame and the protection post, and the sealing frame is pushed by the elasticity of the spring to be upwards abutted to the sealing plate to prevent the sampling head from contacting with dust in the air.

Preferably, the upper end of the sealing plate is provided with a buffer pad, and the buffer pad gives a buffer when the sealing plate contacts the ground downwards.

Preferably, the outer wall of casing is provided with the buffer layer, and the buffer layer adopts the rubber material, improves instrument buffer capacity through the buffer layer.

Preferably, the protective housing has been cup jointed on the surface of casing, the protective housing is located the outside of display screen, fixes a position the protective housing through the frictional force between protective housing and the buffer layer, protects the display screen through the protective housing cage cover outside the display screen.

Preferably, the protective housing adopts the transparent plastics material preparation of ABS to form, sees through the protective housing and can observe display screen surface reading.

Compared with the prior art, the beneficial effects of the utility model are that: according to the detector, the sampling head is arranged on the inner side of the protective column and is covered by the cushion pad, the sealing plate and the sealing frame, so that damage caused by falling can be avoided, and dust can be prevented from entering the detector by the protective column, the sealing frame and the sealing plate; can protect casing and display screen when falling through buffer layer and protective housing.
