Abstract
The utility model relates to a mobile gas detector which comprise a hand-held lever, a prepositive device, a universal coupling between the hand-held lever and the prepositive device, and a gas sensor arranged in the prepositive device, wherein the gas sensor adopts a sulfur hexafluoride and oxygen content dual-gas sensor. The mobile gas detector is provided with the hand-held lever; when the user carries the prepositive device and the hand-held lever, the gas sensor can be conveniently arranged in any region in need of gas detection, thereby enhancing the flexibility and detection range of the gas sensor and facilitating the gas detection; and thus, the operating personnel can detect the gas detection result in real time in a safe region, so the operating personnel does not need to enter the dangerous detection region, thereby ensuring the personal safety of the operating personnel.
Description
Technical field
The present invention relates to a kind of removable gas detection apparatus, be specifically related to a kind of removable sulfur hexafluoride sniffer.
Background technology
At present, the sniffer of the gas of prior art includes removable gas detecting and alarming instrument and stationary gas detection alarm appearance.
Removable gas detecting instrument with component-assembled such as sensor, metering circuit, display, alarm, rechargeable batteries in a housing, the formula that becomes one instrument, small volume and less weight is easy to carry.The shortcoming of this kind detector is; When removable gas detecting instrument carries out testing; The staff carries this detector and gets in the zone that is scattered with harmful gas and detect, and harmful gas might cause danger to staff's personal safety, lacks safe distance;
The stationary gas detector is fixed on the scene that needs detection, and the corresponding harmful gas of continuous automatic inspection, harmful gas transfinite and report to the police automatically, and what have also can control exhaust blower etc. automatically.Fixed instrument is divided into integral type and split type two kinds.The fixed gas detection alarm appearance of integral type: the same with removable instrument, the different scene that is mounted in, continuous automatic inspection is reported to the police, and is mostly the diffusion type sampling.Split type fixing harmful gas detecting and alarming instrument: sensor and signal transmitting circuit bank are contained in the explosion-proof casing, are commonly called as probe, are installed in scene (hazardous area); Second portion comprises data processing, secondary demonstration, controlling alarm and power supply, is assembled into controller, is commonly called as secondary instrument, is installed in pulpit (harbor).Probe diffusion type sample detecting, secondary instrument display alarm.The shortcoming of such fixed detector is, detector is fixed on and detects on-the-spotly, can not arbitrarily move and adjusts check point, has limited to the sensing range of detector, and the while can't in time be judged the quality of monitoring device, needs the regular stoning truth of people condition.
Summary of the invention
The purpose of this invention is to provide the removable gas detection apparatus that a kind of staff of making uses in the safety zone.
In order to achieve the above object, the present invention provides a kind of removable sulfur hexafluoride sniffer, and this device comprises holding rod, front device, and the joint coupling between holding rod and front device is arranged on the gas sensor in the front device.
Above-mentioned front device comprises housing, and the alarm control circuit that is arranged on enclosure interior.
Front device comprises warning device, and warning device is connected through circuit with described gas sensor, and warning device and described gas sensor are arranged in the housing.
Above-mentioned alarm control circuit is connected through circuit with described gas sensor.
Above-mentioned gas sensor adopts sulfur hexafluoride and oxygen level double gas sensors.
Gas sensor is surveyed the gas at gas detection point place, provides sound and light alarm information to operating personnel through being electrically connected the gas detection data that make alarm control circuit receiver gases sensor detection data.Wherein be lower than or sulfur hexafluoride content concn when exceeding standard when oxygen content, gas sensor promptly sends alerting signal, reports to the police to operating personnel.
The harmful gas sniffer of removable sulfur hexafluoride sniffer of the present invention and prior art is compared; Its advantage is; The present invention is provided with holding rod and joint coupling, carries gas sensor, can easily gas sensor be arranged to the zone that any needs carry out gas detection; Improve the flexibility ratio and the sensing range of gas sensor, can carry out gas detection easily;
The holding rod that the present invention is provided with; Operating personnel can be through the result of electrical communications receiver gases sensor to gas detection in the safety zone of far-end; Operating personnel can be detected the gas detection result in the safety zone in real time; Stopped operating personnel and must get into necessity, guaranteed operating personnel's personal safety with dangerous surveyed area.
Description of drawings
Fig. 1 is the structural representation of the removable sulfur hexafluoride sniffer of the present invention;
Fig. 2 is the module map of the removable sulfur hexafluoride sniffer of the present invention.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present invention is described.
As shown in Figure 1, the present invention has explained a kind of removable sulfur hexafluoride sniffer, comprises holding rod 1, front device 2, and the joint coupling 4 that holding rod 1 and front device are 2 is arranged on the gas sensor 3 in the front device.
Wherein gas sensor 3 adopts sulfur hexafluoride and oxygen level double gas sensors.It comprises oxygen level sensor and sulfur hexafluoride sensor; Oxygen level sensor adopts Japan or German imported product, and can arrive 5 years serviceable life, and investigative range is between 14%～26%; When oxygen content is lower than 18.6%, send alerting signal, can satisfy the requirement of this device.Gas sensor 3 is connected with alarm control circuit 22, and alarm control circuit 22 connects warning device 23.
The operation workflow of the removable sulfur hexafluoride sniffer of the present invention is described below in conjunction with Fig. 2.
Carry monitoring device to the zone that needs monitoring by operating personnel, the gas-monitoring point is monitored according to the monitoring needs.
The gas at 3 pairs of gas detection points of gas sensor place is surveyed, and detection data information is sent to alarm control circuit 22, the gas detection data of getter body sensor 3.Wherein when oxygen content is lower than 18.6% or sulfur hexafluoride content concn when arriving 1000ppm, warning device 23 promptly sends alerting signal, reports to the police to operating personnel.
Although content of the present invention has been done detailed introduction through above-mentioned preferred embodiment, will be appreciated that above-mentioned description should not be considered to limitation of the present invention.After those skilled in the art have read foregoing, for multiple modification of the present invention with to substitute all will be conspicuous.Therefore, protection scope of the present invention should be limited appended claim.
