Description

Technical Field

[0001] The invention belongs to the technical field of water quantity measurement, and in particular relates to a device and a method for measuring the remaining water quantity in a water storage tank. Background Art

[0002] In a low-temperature environment, ice will form around the tank wall, and the thickness of the ice layer around the tank is uneven, making it difficult to accurately obtain information about the thickness of the ice layer at each location, and thus difficult to estimate the remaining water in the tank. In order to ensure that the amount of water in the tank can meet production needs, it is necessary to measure the remaining water in the tank in real time.

[0003] At present, there is no equipment on the market that can directly measure the remaining water volume in a water tank covered with uneven ice. There is also no ready-made set of hardware and software equipment that can implement the new measurement method we proposed. Therefore, it is necessary to develop a set of hardware and software equipment including a control calculation system and a measurement system. The control module controls the water depth pressure gauge and flow meter through wireless transmission signals to achieve real-time synchronous measurement at a set Δt time interval. The signal is transmitted wirelessly to the calculation module, and the remaining water volume is calculated by the preset software, and then transmitted to the client display module to monitor the remaining water volume in real time.

[0004] In view of this, the present invention is proposed. Summary of the invention

[0011] The control calculation unit is used to process the information data returned by the flow monitoring unit and the water depth pressure detection mechanism, and transmit it wirelessly to the mobile terminal.

[0012] The device for measuring the amount of water remaining in a water storage tank is characterized in that the winding mechanism includes a winding sleeve, which is sleeved on the shaft rod, and threaded screws are fixed at both ends of the shaft tube, a positioning plate is fixed to one end of the shaft tube, a horizontal locking bolt is installed on the positioning plate, and a brake disc is fixed to the end of the winding sleeve close to the positioning plate; a clamping plate is sleeved on the threaded screw rod, and a locking nut is threadedly screwed on the threaded screw rod located outside the clamping plate

[0013] The present invention also discloses a method for measuring the remaining water volume in a water storage tank, comprising the following steps:

[0014] Step S1: clamp the clamping plates at both ends of the winding sleeve on the outer wall of the upper end of the water storage tank;

[0015] Step S2: The winding sleeve rotates to lower the wound liquid level sensor so that the liquid level sensor falls to the bottom of the inner cavity of the water storage tank;

[0016] Step S3: Install a flow sensor in the drainage pipe of the water storage tank, and the control module in the control computing system transmits the data of the liquid level sensor and the flow sensor to the computing module in the control computing system, and finally displays it through the display module;

[0017] Step S4: Calculate the remaining water volume based on the real-time synchronous measurement of the water depth change and water volume change.

[0018] As a preferred embodiment of the present invention, the wireless communication module in the control computing system is connected to the operator's mobile terminal by wireless communication.

[0019] As a preferred embodiment of the present invention, in step S2, the locking nuts on the threaded screws at both ends of the rotating shaft are used to squeeze and lock the clamping plate on the outer wall of the upper end of the water storage tank to ensure the stability of the shaft.

[0020] As a preferred embodiment of the present invention, in step S3, the locking bolts need to be loosened first, and after the brake disc 9 is not locked, the brake disc 9 and the end of the winding sleeve 6 are fixed.

[0021] As a preferred embodiment of the present invention, in step S4, the water depth change Δh and the volume ΔV of the outflowing water are obtained by synchronously measuring the water depth pressure gauge and the flow meter at a time interval of Δt, and the local cross-sectional area S of the water tank is first calculated, and the calculation formula is as follows:

[0022]

[0023] Assuming the cross-sectional area is uniform, calculate the volume V of the remaining water using the following formula:

[0024] V=Sh。

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] The present invention uses a water depth pressure gauge and a flow meter to synchronously measure, obtain the water depth change Δh at a time interval of Δt, and the volume ΔV of the outflowing water, calculate the local cross-sectional area S of the water tank, and assume that the cross-sectional area is uniform, and the volume V of the remaining water can also be calculated (different calculation formulas can be used for containers of different shapes). This method can measure continuously in real time, and even if the cross-sectional area changes continuously, it can be continuously updated in real time, and the volume of the remaining water can be calculated by averaging or other intelligent algorithms to improve the prediction accuracy.
