Description

Point type toxic gas detector

Technical Field

The utility model belongs to the technical field of the toxic gas detector, concretely relates to point type toxic gas detector.

Background

For places such as oil refineries, drilling platforms, compressor stations, fuel supply stations, chemical plants, liquefied gas storage areas, etc., fire prevention is a very important thing; if a fire occurs, the whole production area is likely to have huge danger; therefore, fire detectors applied to these sites are very important; traditional combustible gas detector has relevant mechanical modulation part, seldom adopts the sensor, and the detector of sensor is adopted to the part, and its detecting head has been used for a long time in the environment that pollutes and has been corroded easily, and its sensitivity is more and more poor, does not have obvious warning alarm or reminds the alarm far away with detector connection distance moreover, and the installation is more loaded down with trivial details, therefore we need the poisonous gas detector of main point type to solve above-mentioned problem, satisfy people's demand.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a point type toxic gas detector to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the point type toxic gas detector comprises a shell and an upper cover, wherein the shell and the upper cover are in threaded connection, a cavity is formed inside the shell and the upper cover, an information processing unit is arranged inside the cavity, two wiring holes are symmetrically formed in the front end of the shell, a signal overrun alarm unit is in threaded connection with the wiring holes, and a gas detection unit is arranged at the lower end of the shell.

Preferably, the information processing unit is an integrated circuit board which receives, processes and sends out electric signals.

Preferably, the signal overrun alarm unit is an audible and visual alarm and is in electrical signal connection with the information processing unit.

Preferably, the gas detection unit comprises a gas detection housing and a gas detector inside the gas detection housing, and the gas detector is in electrical signal connection with the information processing unit.

Preferably, a filter screen is installed at the bottom of the gas detection housing.

Preferably, a plurality of mounting feet are arranged on the shell.

The utility model discloses a technological effect and advantage: this some type toxic gas detector, simple structure, the assembly is reasonable, safe and reliable, and the impurity in the environment can be filtered in setting up of filter screen 7 for detectivity is high, and the signal transfinites alarm unit and installs on the casing, and the dismouting maintenance is more convenient.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model provides a point type toxic gas detector as shown in fig. 1, fig. 2, fig. 3 and fig. 4, including casing 1 and upper cover 2,

casing

1 and 2 spiro unions of upper cover and at the two inside vacuole formation, cavity internally mounted have information processing unit 8, two wiring holes 3 have been seted up to 1 front end symmetry of casing, and the spiro union has signal transfinite alarm unit 6 on the wiring hole 3, gaseous detecting element 4 is installed to 1 lower extreme of casing.

Specifically, the information processing unit 8 is an integrated circuit board that receives, processes, and sends out electrical signals.

Specifically, the signal overrun warning unit 6 is an audible and visual alarm and is electrically connected with the information processing unit 8.

Specifically, the gas detection unit 4 includes a gas detection housing and a gas detector inside the gas detection housing, and the gas detector is electrically connected to the information processing unit 8.

Specifically, a filter screen 7 is installed at the bottom of the gas detection housing.

Specifically, the housing 1 is provided with a plurality of mounting legs 5.

The working principle is as follows: this some type toxic gas detector, when using, pass through gas detecting element 4 as toxic gas, gas detecting element 4 can be to a voltage signal of outer output, this signal is directly proportional with external gas concentration, information processing unit 8 is responsible for enlargiing the signal of gas detecting element 4 output this moment and corrects, provide stable and high-fidelity signal source for next stage, and carry out digital conversion and operation back with the singlechip, with signal output to signal transfinite alarm unit, be used for outputting alarm signal when exceeding the setting value to gas concentration, drive audible-visual annunciator, send audible-visual annunciator, remind people in time to make emergency treatment.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
