Description

Technical Field

[0001] The invention relates to the field of fluid measurement, in particular to an automatic timing and flow measuring barrel. Background Art

[0002] The measuring bucket is a tool widely used in scientific research and daily life. In the agricultural field, it can ensure accurate filling and distribution of pesticides and fertilizers each time. In the field of new energy, such as the production process of electric vehicles, solar panels and other products, it can accurately measure the amount of liquids such as battery fluid and coolant. In the field of water conservancy, in the daily operation of hydropower stations, in order to meet the water demand for maintaining the ecological environment of the river, the amount of water discharged by the hydropower station to the original river channel in a timely and sufficient manner is called ecological flow. The method of collecting water with a measuring bucket is often used on site to calibrate the ecological flow. However, in the process of water collection and calibrating, since the water is collected with a bucket and the stopwatch is operated for timing at the same time, one person often cannot complete the timed water collection work, and two people are required to cooperate to complete it. In the process of cooperation between the two people, they will be restricted by terrain, the line of sight of the observer is blocked, and the cooperation between the two people is not smooth, resulting in large errors in the flow calibration results. Summary of the invention

[0003] In order to solve the above-mentioned problem that when using a measuring bucket to collect water to calibrate the ecological flow of a hydropower station, the flow calibration result has a large error due to the need for two people to cooperate and being easily interfered by various factors, the present invention provides an automatic timing and flow measuring bucket which integrates automatic timing and liquid volume measurement.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0005] The present invention comprises a barrel body, an automatic timing device and a water level sensor. The automatic timing device is arranged on the outer side wall of the upper part of the barrel body. The automatic timing device comprises an infrared transmitter, a reflecting plate and a timer. The infrared transmitter is arranged on the outer side wall of one side of the upper part of the barrel body. The reflecting plate is arranged on the side wall of the other side of the upper part of the barrel body facing the infrared transmitter. The water level sensor is arranged on the inner side wall of the lower part of the barrel body and is in contact with and connected to the inner bottom surface of the barrel body.

[0006] It also includes a controller and a display screen, which are arranged on the outer side wall of the upper part of the barrel body. The timer and the water level sensor in the automatic timing device are electrically connected to the controller respectively, and the controller is electrically connected to the display screen.

[0007] A through hole is provided at the side wall of the barrel body facing the reflecting plate, and the infrared rays emitted by the infrared emitter are used to pass through the side wall of the barrel body through the through hole and irradiate onto the reflecting plate.

[0008] The side wall of the barrel body is provided with scale marks from bottom to top.

[0009] The water level sensor is located just below the display screen.

[0010] The barrel body is made of corrosion-resistant and easy-to-clean material.

[0011] Before using the automatic timing flow measuring bucket to receive liquid, start the controller first, and the controller will synchronously activate the automatic timing device and the water level sensor;

[0012] The automatic timing flow measuring bucket starts to receive liquid, and the liquid flows through the automatic timing device and enters the bucket, blocking the infrared rays emitted in real time between the transmitter and the reflector. The timer starts immediately, records the time when the liquid starts to flow, and sends it to the controller;

[0013] When the liquid in the automatic timing flow measuring bucket submerges the infrared transmitter of the automatic timing device, the timer automatically stops timing and records the time when timing stops;

[0014] The controller combines the timing information of the two timing times with the liquid water level information provided by the water level sensor, and obtains the average flow rate of the liquid flowing into the automatic timing flow measuring bucket after processing.

[0015] The automatic timing device emits infrared rays through an infrared transmitter and feeds back the received signal from the reflector to determine whether the current state is a state of liquid flowing and not submerged, or a state of submerged. The specific determination conditions are:

[0016] When the infrared signal received from the infrared transmitter and fed back from the reflective plate is A% lower than the signal strength of the infrared signal initially emitted by the infrared transmitter, it is determined that the current state is in a state of liquid flow and not submerged, where A represents a first proportional value;

[0017] When the infrared transmitter emits infrared rays and the infrared signal received from the reflective plate is fed back and the signal strength is reduced by B% compared to the infrared signal initially emitted by the infrared transmitter, and B>T>A, it is determined that the current state is flooded, where B represents the second ratio value and T represents the preset critical flood ratio threshold.

[0018] The technical solution provided by the present invention has the following effects:

[0019] The present invention combines the timing and liquid measuring functions, achieving the convenience of single-person operation without the need for two-person cooperation in traditional methods, thereby improving work efficiency; an electronic timer and a liquid level sensor are used to synchronously measure time and liquid volume, thereby reducing timing and reading errors caused by human factors and improving data reliability and accuracy; the device is equipped with a data storage function, capable of recording measurement data in real time, facilitating subsequent data analysis and processing.

[0024] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] The three-dimensional main view of the automatic timing flow measuring bucket is as follows Figure 1 As shown, it includes a barrel body 1, an automatic timing device 2 and a water level sensor 3. The barrel body 1 is used to contain liquid. The automatic timing device 2 is arranged at the outer side wall of the upper part of the barrel body 1. The automatic timing device 2 includes an infrared transmitter, a reflective plate 6 and a timer. The infrared transmitter and the timer are integrated into a structure. The infrared transmitter is arranged at the outer side wall of one side of the upper part of the barrel body 1. The reflective plate 6 is arranged on the side wall of the other side of the upper part of the barrel body 1 opposite to the infrared transmitter. The automatic timing device 2 is placed outside the barrel mouth and connected to the barrel body 1. It has an infrared transmitter, which emits infrared rays to the reflective plate 6 on the opposite side. When liquid flows into the barrel body 1, the automatic timing device 2 can sense the inflow of liquid through infrared rays and start timing. When the liquid stops flowing in or the liquid submerges the infrared transmitter of the automatic timing device 2, the timing stops automatically; the water level sensor 3 is arranged at the inner side wall of the lower part of the barrel body 1 and is in contact with the inner bottom surface of the barrel body 1. It is used to monitor the liquid level height and changes in real time, and uses the water pressure measurement principle to measure the water level in the barrel.

[0026] The electrical connection structure of the automatic timing and flow measuring barrel of the present invention is as follows Figure 3 As shown, it also includes a controller 4 and a display screen 5. The controller 4 and the display screen 5 are arranged on the upper outer wall of the barrel body 1. The timer and the water level sensor 3 in the automatic timing device 2 are electrically connected to the controller 4 respectively, and the controller 4 is electrically connected to the display screen 5. Specifically, the water level sensor 3 transmits information to the controller 4 in real time. The controller 4 records the data from the automatic timing device 2 and the water level sensor 3, controls the start and end of the timing operation, and calculates the total inflow time and / or average flow rate of the liquid. The display screen 5 is used to display the timing results, liquid volume and average flow rate. The controller 4 includes a data storage module that can save the timing and liquid volume data in the barrel measured multiple times.

[0027] In a specific implementation, the controller 4 can also directly record the data from the automatic timing device 2 and the water level sensor 3 to control the start and end of the timing operation. Based on the measured water level height, considering that the barrel diameter is a known parameter, the volume of the liquid in the barrel can be derived, and the total inflow time and average flow rate of the liquid can be calculated;

[0028] More specifically, the automatic timing device 2 records the start and end of the liquid flowing into the bucket, and transmits the timing information of the continuous liquid inflow to the controller 4. The water level sensor 3 transmits the water level information to the controller 4 in real time. The diameter of the measuring bucket is fixed and known. The controller 4 can convert the water level information into volume information in real time, and calculate the average liquid flow information after receiving the timing information transmitted by the automatic timing device 2. The display screen 5 is used to display the timing results, liquid volume and average flow. The controller 4 includes a data storage module that can save the timing and liquid volume data in the bucket measured multiple times.

[0029] The three-dimensional side view of the automatic timing flow meter bucket is as follows Figure 2 As shown, a through hole is opened at the side wall of the barrel body 1 facing the reflective plate 6, and the infrared light emitted by the infrared transmitter passes through the side wall of the barrel body 1 through the through hole and irradiates the reflective plate.

[0030] The side wall of the barrel body 1 is provided with scale marks 7 from bottom to top. The barrel body 1 can be made of transparent material, and the clear scale marks 7 can be used to observe and verify the liquid volume information.

[0031] Specifically, the water level sensor 3 is located directly below the display screen 5 .

[0032] More specifically, the barrel body 1 is made of a corrosion-resistant and easy-to-clean material and has a standard cylindrical shape, which is suitable for a variety of liquid measurement scenarios.

[0033] The use process of the automatic timing and flow measuring bucket is as follows: before using the automatic timing and flow measuring bucket for water collection, the operator first starts the control system, which will synchronously activate the automatic timing device 2 and the water level sensor 3; during the water collection process, once the liquid flows through the infrared detection area of ​​the automatic timing device 2 and enters the bucket, the timer starts immediately and accurately records the time; when the liquid in the bucket reaches the preset capacity or submerges the infrared transmitter of the automatic timing device 2, the timing stops automatically, and the operator needs to evacuate the bucket safely from the water source area with quick and smooth movements. At this time, the automatic timing device 2 accurately terminates the timing process by receiving the signal fed back by the reflector 6; the control system integrates the timing data and the liquid volume information provided by the water level sensor 3 to automatically calculate the precise flow rate of the liquid.

[0034] The process of using the automatic timing flow measuring bucket is as follows: before using the automatic timing flow measuring bucket to receive liquid, the operator first starts the controller 4, and the controller 4 will synchronously activate the automatic timing device 2 and the water level sensor 3;

[0035] The automatic timing flow measuring bucket starts to receive liquid and in the process of receiving liquid, the liquid flows through the infrared detection area of ​​the automatic timing device 2 and enters the bucket, blocking the infrared rays emitted in real time between the emitter and the reflector 6. Specifically, when the liquid passes through the area where the infrared rays are emitted in real time between the infrared emitter of the automatic timing device 2 and the reflector 6, the infrared rays are blocked. After the infrared rays are blocked, the infrared emitter control timer in the automatic timing device 2 is started immediately, and the time when the liquid starts to flow is accurately recorded and sent to the controller 4.

[0036] When the liquid in the automatic timing flow measuring bucket reaches the preset capacity or submerges the infrared emitter of the automatic timing device 2, the infrared emitter controls the timer to automatically stop timing and record the time of stopping timing because the infrared rays emitted by the infrared emitter to the reflective plate and reflected back are further blocked. The operator needs to stop the automatic timing flow measuring bucket from receiving water with quick and smooth movements and safely evacuate the water source area;

[0037] The controller 4 combines the timing information of the two timing times with the liquid water level information provided by the water level sensor 3, and obtains the accurate average flow rate of the liquid flowing into the automatic timing flow measuring bucket after processing.

[0038] More specifically, the automatic timing device 2 emits infrared rays through an infrared transmitter and feeds back the received signal from the reflector 6 to determine whether the current state is a state of flowing liquid and not submerged, or a state of submerged. The specific determination conditions are:

[0039] When the infrared signal emitted by the infrared emitter and fed back from the reflective plate 6 is A% lower than the signal strength of the infrared signal initially emitted by the infrared emitter, it is determined that the current state is in a state of liquid flow and not submerged, where A represents a first proportional value;

[0040] When the infrared transmitter emits infrared rays and the infrared signal received as feedback from the reflective plate 6 is reduced by B% compared to the signal strength of the infrared signal initially emitted by the infrared transmitter, and B>T>A, it is determined that the current state is flooded, where B represents the second proportion value and T represents the preset critical flood proportion threshold.

[0041] Therefore, the automatic timing device 2 accurately terminates the timing process by receiving the signal fed back by the reflection plate.

[0042] It can be seen from the above embodiments that in the water receiving operation, the operator only needs to simply start the control system, and the system will automatically activate the timing and water level monitoring functions, accurately track the liquid accumulation until the preset conditions are met, thereby improving the operation speed, ensuring the accuracy of the metering results, and achieving dual optimization of high efficiency and high precision in the entire water receiving process.
