In one embodiment of the present device, the bottom center of the tank 11 is provided with a liquid outlet hole, and a downward pipe joint is installed for connection with the communication pipe 2.
Referring to fig. 2, in order to fix the raw liquid tank 1 to a reference position, a multipurpose fixing plate 13 is welded to the outer wall of the tank 11; the multipurpose fixing plate 13 is L-shaped, and the vertical section thereof is provided with two parallel holes one of which is a long hole and vertical (relative drawing) so as to allow a rivet and a bolt to pass through, thereby fixing the stock solution tank 1 on a certain vertical plane (wall, wood board).

The top surface of the cap 12 decreases in height from proximate the plunger 14 to the periphery.
When in use, a user pulls up the plunger 14 to enable the limiting ring 15 to extrude the top cover 12 and finally prop against the upper surface of the top cover 12; at this time, the coordination hole on the plunger 14 and the air pressure balance hole on the top cover 12 are communicated with the inside of the tank 11 to realize air pressure balance.
If a weather is encountered, the plunger 14 may be directly depressed to close the cap 12 to prevent rainwater from entering the tank 11.
Referring to fig. 2 and 3, an atmospheric pressure sensor 7 is mounted on an upper portion of the plunger 14 and fixed by bolts; the atmospheric pressure sensor 7 is connected to the above-mentioned battery.
In an embodiment of the device, the device further comprises a processing module 8, i.e. a control board integrated with the processing chip.
In order to protect and fix the processing module 8, a three-proofing case can be optionally matched, the solar panel can be installed on the top of the case, and the processing module 8, a storage battery and other accessory circuit structures are accommodated inside the case.
The processing module 8 is electrically connected with the battery, the membrane pressure sensor 4, the data transmission module 6 and the atmospheric pressure sensor 7, respectively, with adapted terminals.
As is known, the data transmission module 6 is controlled by a processing module 8, serving as an upload of the detection values for the individual sensors. Meanwhile, in the present embodiment, the processing module 8 is further configured to:
receiving and acquiring a real-time air pressure detection value fed back by an atmospheric pressure sensor 7 and an end-to-end hydraulic value fed back by a membrane type pressure sensor 4;
comparing the real-time air pressure detection value with a pre-stored standard air pressure value (standard atmospheric pressure) to obtain an air pressure difference value;
and judging whether the air pressure difference exceeds an allowable limit value, and if so, sending an air pressure difference and an overrun prompt message through the data transmission module 6.
According to the setting, the device can detect the air pressure of the construction site, give a prompt when the air pressure is abnormally large, and avoid misjudgment of a user caused by low pressure caused by extreme weather (typhoon and the like).
Further, the processing module 8 is configured to: and searching a pre-stored air pressure difference influence database (namely, one-to-one corresponding parameters of the air pressure difference and the end direction influence quantity obtained by realizing experiments) according to the air pressure difference value, obtaining a matched end direction influence quantity, updating an end direction hydraulic value (adding or subtracting) by the end direction influence quantity, obtaining a corrected end direction hydraulic value, and sending the corrected end direction hydraulic value through a data transmission module.
It will be appreciated that the arrangement described above helps to improve the accuracy of the sedimentation detection.
Referring to fig. 2, in one embodiment of the present application, a liquid level sensor 91 is mounted in the tank 11; meanwhile, a transverse water inlet pipe is fixedly inserted into the side wall of the tank body 11, an adaptive electromagnetic valve 92 is arranged on the water inlet pipe, and the electromagnetic valve is used for communicating a water pipe of a construction site.
Both the liquid level sensor 91 and the solenoid valve 92 can be powered by the above-mentioned accumulator; and are respectively connected to the processing modules 8. On the premise, the processing module 8 is configured to:
receiving and acquiring a real-time liquid level detection value fed back by a liquid level sensor;
comparing the real-time liquid level detection with a pre-stored initial liquid level value to obtain a liquid level difference value;
introducing a time parameter (time axis) to obtain a liquid level change trend;
if the liquid level change trend is rising, sending a real-time liquid level detection value and a pipeline pressure prompt through a data transmission module;
if the liquid level change trend is descending and the liquid level difference reaches the pre-stored water supplementing parameter, the electromagnetic valve is controlled to be opened.
It will be appreciated that the communication tube 2 in the form of a hose is inevitably pressurized at the site if the user is not protected with a special casing; at this time, the liquid level abnormally rises and returns after a few seconds.
Whereas the above-mentioned level drops, in this embodiment the evaporation of water is considered; because the raw liquid tank 1 is used in an open mode, and is influenced by ambient temperature and the like, the evaporation rate in part of time period is high, and the device is not disturbed in use and is actively opened and closed by the electromagnetic valve, so that the liquid level balance effect is achieved.
The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
