Abstract
The utility model relates to a device for monitoring a liquid level of a foam solution in a foam solution storage tank in real time. The device comprises a foam solution storage tank and a capsule which is fixed in the foam solution storage tank and is used for filling the foam solution, wherein the bottom of the capsule is provided with an opening; the opening is connected with a pipeline; the other end of the pipeline stretches out of the bottom of the foam solution storage tank; a pressure sensor for monitoring pressure of the foam solution is arranged in the pipeline; and an output end of the pressure sensor is connected with a processor used for processing the pressure of the foam solution into the foam liquid level. By adopting the device, the foam liquid level in the foam solution storage tank can be monitored in real time, and remote monitoring can be realized.
Description
Technical field
The utility model belongs to the foam liquid tank technical field, more specifically, relates to a kind of foam liquid tank inner foam liquid level real time monitoring device.
Background technology
Foam liquid tank is very important parts in the froth fire extinguishing system, foam solution then is the important fire extinguishing source of foam liquid tank, in actual fire-fighting work, the fire fighter needs to control in real time the parameters such as froth level in the foam liquid tank, so that the fire fighter replenishes foam solution in time for the foam liquid tank of foam solution deficiency.
At present the level monitoring method of foam liquid tank is to measure by glass-tube liquid level meter or magnetic flap level gauge, and needs artificial field monitoring when measuring, and can't realize the far-end Real-Time Monitoring.
Summary of the invention
For remedying defects, the utility model proposes a kind of foam liquid tank inner foam liquid level real time monitoring device, can Real-Time Monitoring foam liquid tank inner foam liquid level, and can realize remote monitoring.
In order to achieve the above object, the utility model is achieved by the following technical solutions.
A kind of foam liquid tank inner foam liquid level real time monitoring device, it is characterized in that, comprise foam liquid tank and be fixed on the capsule that is used for the can foam solution in the described foam liquid tank, described capsule bottom is provided with opening, described opening is connected with pipeline, the described pipeline other end stretches out the bottom of described foam liquid tank, be provided with the pressure sensor for monitoring foam solution pressure in the described pipeline, the output of described pressure sensor is connected with for being the processor of froth level with the foam solution pressure treatment.
The characteristics of technique scheme and further the improvement are:
(1) described processor is single-chip microcomputer.
(2) output of described processor is connected with for the display screen that shows froth level.
(3) described capsule bottom opening is connected with described seal for pipe joints.
Adopt the utility model device, in advance pressure sensor is fixed on the inwall of pipeline, pressure sensor passes to processor with foam solution pressure, processor calculates the foam solution height with this foam solution pressure and the foam solution proportion that is arranged in advance in the processor, this foam solution height is exactly that the pressure sensor fixed bit is to the height of liquid level, be froth level, this froth level can show by display screen, so that fire fighter's implementing monitoring.
Description of drawings
Below in conjunction with the drawings and specific embodiments the technical solution of the utility model is described in further detail.
Fig. 1 is the utility model embodiment foam liquid tank inner foam liquid level real time monitoring device schematic diagram;
Wherein, 1, foam liquid tank; 2, capsule; 3, foam solution; 4, pipeline; 5, pressure sensor; 6, processor; 7, display screen.
The specific embodiment
The single-chip microcomputer of processor selection 8051 series is that example describes among the utility model embodiment.
With reference to the accompanying drawings 1, comprise foam liquid tank 1 and the capsule 2 that is fixed in the foam liquid tank 1, capsule 2 is used for can foam solution 3, capsule 2 bottoms are provided with opening, this opening is connected with pipeline 4, the bottom that pipeline 4 other ends stretch out foam liquid tank 1, be provided with pressure sensor 5 in the pipeline 4, pressure sensor 5 is used for measuring the pressure of foam solution 3, the output of pressure sensor 5 is connected with processor 6, the pressure treatment that processor 6 is used for foam solution 3 is froth level, and shows this froth level by display screen 7.Capsule 2 bottom openings and pipeline 4 are tightly connected, if blow-by is equivalent to capsule 2 breakages, will directly cause whole froth fire extinguishing system paralysis.
Adopt the utility model device, in advance pressure sensor 5 is fixed on the inwall of pipeline 4, pressure sensor 5 is measured the pressure of foam solution 3, and foam solution pressure is input to processor 6, processor 6 calculates the foam solution height with this foam solution pressure and the foam solution proportion that is arranged in advance in the single-chip microcomputer, computational methods are: H=P/ ρ, P is pressure in the formula, H is the foam solution height, ρ is foam solution proportion, and the foam solution height is exactly that the pressure sensor fixed bit is to the height of liquid level, i.e. froth level, this froth level can show by display screen, so that fire fighter's implementing monitoring.
The factor that affects the foam solution place value is the fixed position of pressure sensor 5, because the pressure that pressure sensor 5 is measured is the pressure of fixing these pressure sensor 5 places, because foam solution proportion is constant, pressure becomes then, and froth level becomes, therefore, select suitable pressure sensor fixed position, capsule 2 inner foam level gauging values will be more accurate.
The utility model device, in case successful installation when carrying out actual foam level gauging, will be finished automatically, the fire fighter only need observe the numerical value of froth level on the display screen, and foam solution in the foam liquid tank what are just known.Therefore, not only can Real-Time Monitoring, also can remote monitoring.
The utility model also has numerous embodiments, in every case in spirit of the present utility model and essential scope, any change of doing, is equal to and replaces and improve, all within protection domain of the present utility model.
