Description

Technical Field

[0001] The invention relates to a device for remotely and automatically detecting a standard water storage container used in an automatic detection device of a tipping bucket type rainfall sensor. Background Art

[0002] The rainfall standard equipment currently used in China is mainly composed of standard water storage containers (also known as rainfall standard balls) and auxiliary equipment. The volumes of rainfall standard balls are 200mL, 314mL and 397mL respectively. Since the volume changes in the standard water storage container will inevitably occur during use, such as due to the adhesion of scale, etc., it is necessary to conduct regular inspections. At present, when inspecting the standard water storage container, it is removed and installed on the bracket of the detection device. The water inlet parameters are set by the data acquisition system to add water to the rainfall standard ball. After filling with water, the water outlet parameters are set by the data acquisition system to discharge the water in the rainfall standard ball into the weighing cup. After the water is discharged, the mass of the water in the measuring cup is weighed with an electronic balance. At the same time, according to the requirements of the inspection, the inspection process is carried out at a certain temperature, or the volume value at a certain temperature is converted by measuring the temperature of the water being tested, so as to detect the accurate volume and other data of the standard water storage container.

[0003] Due to the widespread use of automatic rain gauges, there is a need for remote and automatic regular inspection and calibration of rain gauges. The Chinese invention patent application No. 202111034399.1 proposed by the applicant discloses such a device, but the device itself does not have the function of inspecting the container itself of the standard water storage container used, nor can it realize inspection under certain temperature conditions, which severely limits its application. Summary of the invention

[0004] The invention provides a device which can solve the problem that the prior art cannot solve and can automatically detect a standard water storage container remotely.

[0005] The invention discloses an automatic detection device for a standard water storage container, comprising: a device for fixing the standard water storage container, a water inlet valve, a water inlet pump, a water storage container, a water level sensor placed on the standard water storage container, a temperature sensor, a mass sensor, a weighing container placed on the mass sensor, a water outlet pump, a water outlet valve, a data collection and calculation display module, and connected pipelines and data transmission lines, wherein a water outlet pipe of the standard water storage container is connected to one port of a tee, the other two ports of the tee are respectively connected to the water inlet valve and the water outlet valve, the input port of the water inlet valve is connected to the water storage container through the water inlet pump, the output port of the water outlet valve is connected to the weighing container placed on the mass sensor through the water outlet pump, and the data collection and calculation display module is respectively connected to the water inlet and outlet valves; the water inlet and outlet pumps; the temperature sensor and the mass sensor through transmission lines or control lines.

[0006] Preferably, in the device for automatically detecting a standard water storage container of the present invention, a remote transmission information unit is provided in the data collection, calculation and display module, so that the detection data and control actions during the detection process can be visualized and controlled by the operator.

[0007] The device of the present invention can automatically and accurately detect the standard water storage container, thus solving the problem that the volume of the standard water storage container cannot be automatically detected in the prior art application. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0009] The present invention is explained in detail below with reference to the accompanying drawings.

[0010] See attached Figure 1 The present invention is provided with a standard water storage container fixing device (not shown in the attached drawings) for fixing the standard water storage container 1 to be measured, a water level sensor is provided outside the standard water storage container, a standard water storage container outlet pipe 14 of the standard water storage container 1 is connected with a port of a tee 11, two ports of the tee are respectively connected with an inlet valve 2 and an outlet valve 10, the inlet valve 2 is connected with a water reservoir 4 through an inlet pipeline and an inlet pump provided therein; the outlet valve is connected with a weighing container 7 through an outlet pipeline and an outlet pump provided therein, and the weighing container is placed on a mass sensor 6. The present invention is also provided with a temperature sensor 5 in the water reservoir 4. Each valve and pump in the present invention is an electrically controlled valve and an electrically controlled pump, and each valve and pump, as well as the control end and the detection data end of the temperature sensor and the quality sensor are connected to the data collection and calculation module 12 by a data line. The module 12 adopts a programmable processor or a single-chip microcomputer or other types of microprocessors and displays with data processing functions, which are used to control water inlet and outlet, and automatically collect parameters such as water temperature and water quality measured by a balance, and run a series of verification processes and calculation functions to realize various functions such as data collection, analysis, diagnosis, debugging and control. The module 13 is used to monitor whether the water in the standard water storage container is at the scale water level line.

[0011] When the device of the present invention is used for detection, the standard water storage container is first removed and installed on the standard water storage container fixing device, and the data collection calculation and display module 12 gives instructions to open valve 2 and close valve 10, and the water inlet pump 3 is turned on to inject the water in the water storage container 4 into the standard water storage container 1 through the water inlet parameters set by the acquisition system. After the standard water storage container is filled with water, the module 12 gives instructions to close valve 2 and open valve 10, close the water inlet pump 3 and turn on the water outlet pump 9 to discharge the water into the weighing container 7. When the water level sensor 13 detects that the water in the standard water storage container 1 is at the scale water level line, that is, the water in the standard water storage container has been completely discharged, the water outlet pump 9 is turned off and the mass of the injected water is measured by the mass sensor 6, and the temperature of the water measured by the temperature sensor 5 is collected at the same time. The accurate volume of the standard water storage container at a certain temperature is obtained by calculation, and the detection operation of the standard water storage container is realized. When a remote transmission unit is provided in the device of the present invention, the data can be transmitted to a terminal in a different place through the remote transmission unit for the terminal staff to view and adjust and control.
