Description
Technical field
The utility model relates to a kind of safety monitoring assembly, refers to a kind of safety monitoring assembly of LNG charging machine especially.
Background technology
Combustion gas probe in the market and charging machine are physically separated installation, and control mode be station level have independently supervisory system, when breaking down, the electric power system of whole station level is cut off.The installation site of current combustion gas probe is in a larger region, usually above the outlet being arranged on filling gun or directly over charging machine, the shortcoming one of this installation is that the sensitivity of combustion gas probe detection concentration is lower, charging machine is once leakage and leakage rate is few, rock gas can be diluted in atmosphere, thus not easily by combustion gas probe monitors.Two is that after combustion gas probe detects leakage rate, action control scope is excessive, and the combustion gas probe between adjacent charging machine may exist interference, thus causes monitoring inaccurate, has a certain impact to gas station does business constantly.
Utility model content
Technical problem to be solved in the utility model is: the safety monitoring assembly providing a kind of LNG charging machine, and this safety monitoring assembly can monitor the leakage situation of charging machine accurately, and the interference between adjacent charging machine is little, and reliability standard is high.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of safety monitoring assembly of LNG charging machine, comprise combustion gas probe, described combustion gas probe is installed on the body of charging machine, this body comprises the cloth tube chamber that is positioned at bottom, the column chamber being positioned at the element installation cavity for mounting electrical element above cloth tube chamber and being positioned at outside element installation cavity, this column chamber is communicated with described cloth tube chamber and is positioned at the top of cloth tube chamber, described combustion gas probe is installed on the chamber wall in column chamber, the chamber wall in this column chamber is provided with monitoring mouth, this monitoring mouth is positioned at the below of combustion gas probe.
As the preferred scheme of one, the overhead height in described column chamber is higher than the top of element installation cavity.
As the preferred scheme of one, the quantity in described column chamber is two and is positioned at the both sides of element installation cavity, and described combustion gas probe is installed on the chamber wall in one of them column chamber, and this chamber wall is adjacent with another column chamber.
As the preferred scheme of one, the quantity of described monitoring mouth is one and pops one's head in combustion gas to be in the same side.
As the preferred scheme of one, the quantity of described monitoring mouth is two, and these two monitoring mouths lay respectively on the chamber wall in two column chambeies.
As the preferred scheme of one, described two monitoring mouths lay respectively on the relative chamber wall in two column chambeies.
As the preferred scheme of one, the height of described two monitoring mouths are equal, this monitoring mouth and combustion gas pop one's head between distance be less than distance between the top of monitoring mouth and element installation cavity.
As the preferred scheme of one, described monitoring mouth is made up of some equally distributed apertures.
After have employed technique scheme, effect of the present utility model is: due to a kind of safety monitoring assembly of LNG charging machine, comprise combustion gas probe, described combustion gas probe is installed on the body of charging machine, this body comprises the cloth tube chamber that is positioned at bottom, the column chamber being positioned at the element installation cavity for mounting electrical element above cloth tube chamber and being positioned at outside element installation cavity, this column chamber is communicated with described cloth tube chamber and is positioned at the top of cloth tube chamber, described combustion gas probe is installed on the chamber wall in column chamber, the chamber wall in this column chamber is provided with monitoring mouth, this monitoring mouth is positioned at the below of combustion gas probe, so when leaking appears in charging machine, the rock gas leaked can directly upwards flow from cloth tube chamber and enter in column chamber, final concentrating is flowed out from monitoring mouth, owing to being the cluster sampling of little confined space, the leakage energy accurate response that combustion gas probe occurs for charging machine inside, certainly because combustion gas probe is in the top of charging machine, therefore also can reflect more accurately for spatial leaks.Can the inspection of separate unit machine when concentration is and reports to the police, and do not affect other business of station level.Embody the relative independentability of charging machine self-inspection.Simultaneously when leakage rate is excessive, automatically cut off the electric power system of self, up-delivering signal is used for centralized management to PLC simultaneously.
Again because the overhead height in described column chamber is higher than the top of element installation cavity, so the top in column chamber has enough installing spaces, facilitates the installation that combustion gas is popped one's head in, and the height that combustion gas is popped one's head in is higher than the top of element installation cavity.
Again because the quantity in described column chamber is two and is positioned at the both sides of element installation cavity, described combustion gas probe is installed on the chamber wall in one of them column chamber, and this chamber wall is adjacent with another column chamber.Like this, a combustion gas probe is utilized to get final product the gas leakage situation of monitoring element installation cavity both sides.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of prior art;
Fig. 2 be the utility model embodiment structural representation;
In accompanying drawing: 1. charging machine; 11. cloth tube chambers; 12. element installation cavitys; 13. column chambeies; 2. combustion gas probe; 3. support; 4. monitor mouth.
Embodiment
Below by specific embodiment, the utility model is described in further detail.
As shown in Figure 1, current safety monitoring assembly is separated with charging machine 1, and namely utilize support 3 that combustion gas probe 2 is extended the top of charging machine 1, this combustion gas probe 2 connects in the controls, and figure section line part illustrates the scope that this combustion gas probe 2 can be monitored.Current this safety monitoring assembly monitoring range is too large, and the sensitivity of monitoring is low, may occur that monitoring interference causes monitoring result inaccurate between adjacent charging machine 1.
