Description

High-altitude gas alarm detection equipment

Technical Field

The utility model relates to a check out test set of high altitude gas alarm.

Background

According to national metrological verification regulations such as combustible gas alarm, standard gas is required to be introduced into the gas alarm for detection when the gas alarm is verified. However, a large part of alarms are installed at the high altitude of about 3-6 meters, direct ventilation is difficult, a scaffold needs to be built and dismantled, and the scaffold is conveyed to a laboratory for detection, so that time and labor are consumed.

SUMMERY OF THE UTILITY MODEL

According to the utility model discloses an aspect provides a high altitude gas alarm check out test set, include: the inner pipe and the telescopic outer pipe is sleeved on the inner pipe, the air outlet end of the inner pipe protrudes out of the first end of the outer pipe, and the length of the inner pipe is at least the shortest length of the outer pipe.

The utility model discloses a high altitude gas alarm check out test set can extend according to the various height that gas alarm located, directly carries gas alarm department with standard gas, need not to build the scaffold frame and also need not to tear open the machine and detect, and the operation is very convenient.

In some embodiments, the gas outlet end of the inner tube is fixed to the first end of the outer tube.

In some embodiments, the outer tube is a stepped telescopic structure.

In some embodiments, a diffusion shroud disposed at the gas outlet end of the inner tube is further included.

In some embodiments, the diffuser cap is removably disposed on the inner tube.

Detailed Description

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

Fig. 1 schematically illustrates a high altitude gas alarm detection apparatus according to some embodiments of the present invention, comprising an inner tube 1 and an outer tube 2.

The outer tube 2 is a telescopic hollow tube body, and is sleeved on the inner tube 1. The outer tube 2 may be a telescopic tube having a step-like telescopic structure, which is commonly available in the market, as shown in fig. 5.

Referring to fig. 2, the inner tube 1 has two ends forming an inlet end 12 and an outlet end 11, and correspondingly, the outer tube 2 has two ends forming a first end 21 and a second end 22, the outlet end 11 of the inner tube 1 is adjacent to the first end 21 of the outer tube 2 and slightly protrudes from the first end 21 of the outer tube 2, and the inlet end 12 of the inner tube 1 is adjacent to the second end 22 of the outer tube 2.

When the gas-insulated pipe is used, referring to fig. 2, the gas inlet end 12 of the inner pipe 1 is butted with the external hose 3 of the standard gas, which is equivalent to the extension length of the external hose 3 of the inner pipe 1, at this time, the second end 22 of the outer pipe 2 is extended, referring to fig. 3, the second end 22 of the outer pipe 2 is extended and sleeved on the external hose 3, and the gas outlet end 11 of the inner pipe 1 is not retracted into the first end 21 of the outer pipe 2. After the inner pipe is stretched to the required length, the outer pipe 2 is lifted, the gas outlet end 11 of the inner pipe 1 is close to the gas alarm, standard gas outlet is started, and detection can be carried out. After the detection is finished, the air is closed, the outer pipe 2 is contracted, and the air inlet end 12 of the inner pipe 1 is separated from the external hose 3.

For convenience of operation, it is preferable that the gas outlet end 11 of the inner tube 1 is provided to be fixed to the first end 21 of the outer tube 2 to prevent the gas outlet end 11 of the inner tube 1 from being retracted into the outer tube 2.

The length of the inner tube 1 is at least equal to the shortest length of the outer tube 2, and it is extended by an external hose 3 for standard gas to meet the length requirement of the outer tube 2 when it is deployed. The length of the inner tube 1 may also be set longer, for example corresponding to the longest length of the outer tube 2, and as shown in fig. 4, the air inlet end 12 of the inner tube 1 protrudes a longer length relative to the second end 22 of the outer tube 2 when the outer tube 2 is retracted to the shortest length. The inner tube 1 may be made of a material having a certain flexibility to facilitate storage.

In some embodiments, the gas outlet end 11 of the inner tube 1 is further provided with a diffusion cover 4, and the diffusion cover 4 is used for diffusing the gas in the inner tube 1. The diffuser 4 has a larger diameter than the inner pipe 1, and may be cylindrical or horn-shaped with one end open. Preferably, the diffuser 4 is detachably arranged on the inner tube 1.

What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept of the present invention, several modifications and improvements can be made, or the above technical solutions can be freely combined, including the technical features between the above different embodiments, which all belong to the protection scope of the present invention.
