[0029] A fire extinguisher detection system includes: a volume measurement module, a mass measurement module 5 and a controller.
[0030] The volume measurement module is used to obtain the volume of the fire extinguisher foam to be measured and generate a volume numerical signal. The mass measurement module 5 is used to obtain the mass of the fire extinguisher foam to be measured and generate a mass numerical signal. Among them, the volume measurement module is a liquid volume sensor, and the mass measurement module 5 is a pressure sensor. Among them, the volume measurement module can be a volume measuring instrument using a liquid volume sensor, and the mass measurement module 5 can be an electronic scale using a pressure sensor.
[0031] The controller is used to receive the volume numerical signal generated by the volume measurement module, receive the mass numerical signal generated by the mass measurement module 5, and output the foaming multiple signal of the fire extinguisher foam to be measured. The controller outputs the foaming multiple signal of the fire extinguisher foam to be measured according to the received volume numerical signal and mass numerical signal, and when any one of the received volume numerical signal and mass numerical signal changes, the output foaming multiple signal of the fire extinguisher foam to be measured will also change accordingly.
[0032] Here, the controller may be a calculator or a computer integrated with an operation formula. In order to further express the operation formula, the foaming multiple of the fire extinguisher foam to be measured is defined as N, the volume value is defined as V, and the mass value is defined as M.
[0033] N=V÷M*ρ.
[0034] ρ is the density of the fire extinguisher foam to be measured, calculated as 1KG / L. The unit of V is L, and the unit of M is KG.
[0035] Specifically, the controller includes a control panel, a divider and a power module. The control panel is used to install the divider and the power module. The control panel is used to directly or indirectly install the volume measurement module and the mass measurement module 5. The divider is used to receive the volume value signal, receive the mass value signal and output the foaming multiple signal of the fire extinguisher to be measured; the power module is used to power the divider, the volume measurement module and the mass measurement module 5. The power module is a battery. The control panel is connected to the volume measurement module and the mass measurement module 5 through wires. The divider is used to calculate division, which is to calculate the quotient of the mass value measured by the mass measurement module 5 and the volume value measured by the volume measurement module. Since ρ is 1, the formula can be directly converted into a value obtained by dividing the mass by the volume.
[0036] Specifically, the fire extinguisher detection system also includes a bracket 1, a measuring frame 2, a mobile carrier 3 and a scraper 4. The bracket 1 is used to install the measuring frame 2, the volume measurement module, the mass measurement module 5 and the controller; the measuring frame 2 is used to form a containing chamber for containing the fire extinguisher foam to be measured. The inner wall surface and the outer wall surface of the containing chamber are both cylindrical surfaces. The mobile carrier 3 is used to install the bracket 1, so that the combination of the bracket 1 and other parts can be easily moved. The scraper 4 is connected to the bracket 1; the fire extinguisher foam to be measured is taken out of the fire extinguisher by a spray gun and added to the containing chamber; the scraper 4 is used to scrape off the residual fire extinguisher foam to be measured on the inner wall surface and the outer wall surface of the containing chamber.
[0037] More specifically, the scraper 4 includes a first scraper 41, a second scraper 42 and a driving mechanism 43; the driving mechanism 43 is used to simultaneously drive the first scraper 41 and the second scraper 42 to move; the first scraper 41 is used to abut against the inner wall surface of the accommodating chamber, and the second scraper 42 is used to abut against the outer wall surface of the accommodating chamber. The driving mechanism 43 is an electric push rod.
[0038] The mass measurement module 5 measures by removing mass. First, the electronic scale measures the mass of the measuring frame 2 without any material, records this mass as 0, and then continues to measure the mass on this basis, so that only the mass of the fire extinguisher foam to be measured in the containing chamber can be measured.
[0039] In other embodiments, the scraper 4 further includes a cylindrical block 44, a connecting frame 45 and a rotating motor 46. The connecting frame 45 is fixed to the output end of the electric push rod, the rotating motor 46 is mounted on the connecting frame 45, the cylindrical block 44 is fixed to the output end of the rotating motor 46, the first scraper 41 and the second scraper 42 are both mounted on the cylindrical block 44, the first scraper 41 is located above the second scraper 42, and the rotating motor 46 is used to drive the cylindrical block 44 to rotate so as to rotate the first scraper 41 and the second scraper 42.
[0040] The surfaces on which the first scraper 41 and the second scraper 42 face each other are inclined surfaces.
[0041] The above descriptions are only some preferred embodiments of the present disclosure and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by a specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned inventive concept.
