Abstract
The utility model provides a pump suction type multi-parameter sensor comprising a sensor shell and a multi-gas detecting and controlling circuit, a miniature intrinsic safety vacuum pump and a gas circuit switching device which are arranged in the sensor shell, wherein a data transmission interface and four exhaust tube interfaces are arranged on the sensor shell; the exhaust tube interfaces are connected with the gas circuit switching device; the gas detecting and controlling circuit is respectively connected with the miniature intrinsic safety vacuum pump and the gas circuit switching device via electric circuits; the miniature intrinsic safety vacuum pump is respectively connected with the gas detecting and controlling circuit and the gas circuit switching device via gas circuits; and the data transmission interface is connected with the gas detecting and controlling circuit. The sensor provided by the utility model has the advantages that the miniature intrinsic safety vacuum pump with the cost less than 1% of a water ring vacuum pump is adopted, so that the sensor is small and light, has no need on special installation space, can be directly installed like a normal mining sensor and is simple in use and convenient for construction; in addition, the multi-parameter integrated detection circuit is adopted and parameters such as methane, carbon monoxide, carbon dioxide, oxygen, temperature and the like can be simultaneously detected, so that the sensor is high in integration level, low in cost, simple in use and convenient for maintenance.
Description
Technical field
The utility model relates to a kind of sensor, and a kind of especially Study on Protection of Spontaneous Combustion detects the microminiaturized pump suction type multi-parameter sensor of usefulness.
Background technology
Traditional goaf fire detection pumping plant as shown in Figure 1, establish water ring vacuum pump in the goaf fire monitoring pumping plant, water ring vacuum pump is by gas path switching device and gas sample tube, goaf gas is released, send into the gas detecting box, be placed with the sensors such as carbon monoxide, oxygen, methane in the gas detecting box, these sensors are measured the concentration of sample gas the inside carbon monoxide, oxygen and methane, and output to computing machine analysis by data transmission interface.Because water ring vacuum pump and the gas detecting box volume of goaf fire monitoring pumping plant the inside are all larger, weight is greater than 500 kilograms, and cost is also very high, and this monitoring pumping plant need have dedicated location to lay.Overall cost is expensive, and the installation and maintenance difficulty is not suitable for spread.
Summary of the invention
For above-mentioned weak point of the prior art, the utility model provides a kind of Study on Protection of Spontaneous Combustion to detect the microminiaturized pump suction type multi-parameter sensor of usefulness.
To achieve these goals, the utility model provides following technical scheme: a kind of pump suction type multi-parameter sensor, comprise sensor housing and many gases detection control circuits of the section that sets within it, miniature intrinsic safety vacuum pump, gas path switching device, be provided with data transmission interface and a plurality of exhaust tube interface at this sensor housing, described exhaust tube interface links to each other with gas path switching device, described gas detects control circuit and is connected with miniature intrinsic safety vacuum pump and gas path switching device circuit respectively, miniature intrinsic safety vacuum pump detects control circuit with gas respectively and the gas path switching device gas circuit is connected, and described data transmission interface detects control circuit with gas and links to each other.
As preferably: described exhaust tube interface has four.
Can find out by above technical scheme, the utility model small volume and less weight, do not need special fabricating yard, directly equally install by common mine sensors and get final product, can directly will detect data upload to the ground monitoring machine room, using method and traditional mine sensors using method are approximate, and be easy to use, cheap, suit large area to popularize very much.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Fig. 2 is this practical new structural representation.
Embodiment
Further describe the utility model below in conjunction with specific embodiment and accompanying drawing.
As shown in Figure 2, as a kind of embodiment of the present utility model, this pump suction type multi-parameter sensor, it is characterized in that: comprise sensor housing and many gases detection control circuits of the section that sets within it, miniature intrinsic safety vacuum pump, gas path switching device, be provided with data transmission interface and four exhaust tube interfaces at this sensor housing, described exhaust tube interface links to each other with gas path switching device, described gas detects control circuit and is connected with miniature intrinsic safety vacuum pump and gas path switching device circuit respectively, miniature intrinsic safety vacuum pump detects control circuit with gas respectively and the gas path switching device gas circuit is connected, and described data transmission interface detects control circuit with gas and links to each other.Because adopt miniature its cost of intrinsic safety vacuum pump less than one of percentage of water ring vacuum pump, small volume and less weight does not need special fabricating yard, directly equally installs by common mine sensors get final product, uses simply easy construction; Adopt in addition the integrated testing circuit of multiparameter, can detect simultaneously the parameters such as methane, carbon monoxide, carbon dioxide, oxygen, temperature, integrated level is high, and cost is low, uses simple, easy to maintenance.
Goaf gas is under miniature intrinsic safety vacuum pump is twitched during work, through entering vacuum pump behind gas sample tube, the gas path switching device, send into many Detection Circuit by vacuum pump, testing circuit is tested the carbon monoxide in the gas, oxygen, methane, gas concentration lwevel, and detect gas temperature, sampled data reaches computing machine analysis by data transmission interface after processing through this sensor simple analysis.The pump suction type multi-parameter sensor can timesharing detect the gas that the multipath gas sampling pipe is come by the control to gas path switching device.
More than technical scheme that the utility model embodiment is provided be described in detail, used specific case herein principle and the embodiment of the utility model embodiment are set forth, the explanation of above embodiment is only applicable to help to understand the principle of the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, all will change on embodiment and range of application, in sum, this description should not be construed as restriction of the present utility model.
