TECHNICAL FIELD

[0001] The utility model relates to a kind of fluid measurement field, specifically related to an automatic timing flow measuring barrel. BACKGROUND

[0002] The measuring barrel is a tool widely used in scientific research and daily life, which can ensure accurate filling and dispensing of pesticide and fertilizer in agriculture, and accurately measure the amount of battery liquid and cooling liquid in the production process of new energy products such as electric vehicles and solar panels. In the field of water conservancy, the water released from the hydropower station into the original river to meet the water demand for maintaining the ecological environment of the river is called ecological flow. The method of using a measuring barrel to measure water is often used to determine the ecological flow. However, during the water measurement process, the person cannot complete the timing and water measurement work alone, and needs to coordinate with another person. The coordination of two people is affected by factors such as terrain restrictions, blocked view of the person observing the watch, and poor coordination between the two people, resulting in large errors in the flow measurement results. SUMMARY

[0003] To solve the above-mentioned problem of large errors in flow measurement results due to the need for two people to coordinate and be easily affected by various factors when using a measuring barrel to measure the ecological flow of a hydropower station, the utility model provides an automatic timing flow measuring barrel that integrates automatic timing and liquid volume measurement.

[0004] To solve the above-mentioned technical problem, the utility model adopts the following technical scheme:

[0006] The utility model further 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. The controller is electrically connected to the display screen.

[0007] A through hole is formed in the side wall of the barrel body opposite to the reflecting plate, through which the infrared rays emitted by the infrared emitter pass through the side wall of the barrel body and irradiate onto the reflecting plate.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] The three-dimensional front view of the automatic timing flow meter is as follows: Figure 1 As shown, the device includes a tank body 1, an automatic timing device 2, and a water level sensor 3. The tank body 1 is used to contain liquid. The automatic timing device 2 is located on the upper outer wall of the tank body 1. The automatic timing device 2 includes an infrared emitter, a reflector 6, and a timer. The infrared emitter and the timer are integrated. The infrared emitter is located on the upper outer wall of one side of the tank body 1. The reflector 6 is located on the upper side wall of the tank body 1, facing the infrared emitter. The automatic timing device 2 is externally located at the opening of the tank and connected to the tank body 1. It has an infrared emitter that emits infrared rays to the reflector 6 on the opposite side. When liquid flows into the tank body 1, the automatic timing device 2 can sense the liquid flow through infrared rays and start timing. When the liquid stops flowing or the liquid submerges the infrared emitter of the automatic timing device 2, the timing automatically stops. The water level sensor 3 is located on the lower inner wall of the tank body 1 and is in contact with the inner bottom surface of the tank 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 height in the tank.

[0019] The electrical connection structure of the automatic timing and flow measuring barrel of this utility model is as follows: Figure 3 As shown, the system also includes a controller 4 and a display screen 5, which are located on the upper outer wall of the tank 1. The timer and water level sensor 3 in the automatic timing device 2 are electrically connected to the controller 4, 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 capable of storing multiple measurements of timing and liquid volume data within the tank.

[0020] In practice, the controller 4 can also directly record 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, and given that the barrel diameter is a known parameter, the volume of liquid inside the barrel can be derived, and the total inflow time and average flow rate of the liquid can be calculated.

[0021] More specifically, the automatic timing device 2 records the start and end of liquid flow into the tank and transmits the timing information of the continuous liquid flow 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 tank 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 rate 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 rate. The controller 4 includes a data storage module that can save the timing and liquid volume data of multiple measurements.

[0022] A three-dimensional side view of the automatic timing flow meter is shown below. Figure 2 As shown, a through hole is provided on the side wall of the barrel 1 opposite to the reflector 6, through which infrared rays emitted by the infrared emitter pass through the through hole and irradiate the reflector 6.

[0023] The side wall of the barrel 1 is marked with scale markings 7 from bottom to top. The barrel 1 can be made of transparent material. The clear scale markings 7 can be used to observe and verify the liquid volume information.

[0024] Specifically, the water level sensor 3 is located directly below the display screen 5.

[0025] More specifically, the barrel body 1 is made of a corrosion-resistant and easy-to-clean material, and is in the shape of a standard cylinder, making it suitable for various liquid measurement scenarios.

[0026] The automatic timing flow metering bucket is used as follows: Before using the automatic timing flow metering bucket for water collection, the operator first starts the control system, which will simultaneously 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 records the time accurately. When the liquid in the bucket reaches the preset capacity or submerges the infrared transmitter of the automatic timing device 2, the timing automatically stops. The operator must quickly and smoothly remove the bucket safely from the water source area. 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 accurate flow rate of the liquid.

[0027] The automatic timing flow meter is used as follows: Before using the automatic timing flow meter to collect liquid, the operator should first start the controller 4. The controller 4 will simultaneously activate the automatic timing device 2 and the water level sensor 3.

[0028] When the automatic timing flow meter begins to collect liquid, the liquid flows through the infrared detection area of ​​the automatic timing device 2 and enters the water tank, blocking the infrared rays emitted in real time between the transmitter and the reflector 6. Specifically, when the liquid passes through the area between the infrared transmitter and the reflector 6 of the automatic timing device 2, the infrared rays are blocked. After the infrared rays are blocked, the infrared transmitter in the automatic timing device 2 controls the timer to start immediately, accurately record the time when the liquid starts flowing and send it to the controller 4.

[0029] When the liquid in the automatic timing flow metering tank reaches the preset capacity or submerges the infrared transmitter of the automatic timing device 2, the infrared rays emitted and reflected back by the infrared transmitter to the reflector are further blocked. The infrared transmitter controls the timer to automatically stop timing and records the time when the timing stops. The operator must quickly and smoothly stop the automatic timing flow metering tank from receiving water and safely evacuate the water source area.

[0030] The controller 4 combines the timing information from the two timing sessions with the liquid level information provided by the water level sensor 3, and then processes the data to obtain the accurate average flow rate of the liquid flowing into the automatic timing flow measuring tank.

[0031] More specifically, the automatic timing device 2 emits infrared light through an infrared transmitter and receives signals from the reflector 6 to determine whether the current state is one of flowing liquid and not submerged, or one of submerged state. The specific determination criteria are as follows:

[0032] When the infrared signal emitted by the infrared emitter and received from the reflector 6 is reduced by A% compared to the initial infrared signal emitted by the infrared emitter, it is determined that the current state is in a flowing state and not submerged, where A represents the first proportion value.

[0033] When the infrared signal emitted by the infrared transmitter and received from the reflector 6 is reduced by B% compared to the initial infrared signal emitted by the infrared transmitter, and B>T>A, it is determined that the current state is submerged, where B represents the second ratio value and T represents the preset critical submersion ratio threshold.

[0034] Therefore, the timing process is accurately terminated by the automatic timing device 2 receiving the signal fed back from the reflector.

[0035] As can be seen from the above embodiments, in the water collection operation, the operator only needs to simply start the control system, and the system will automatically activate the timing and water level monitoring functions to accurately track the liquid accumulation until the preset conditions are met, thereby improving the operation speed, ensuring the accuracy of the measurement results, and achieving a dual optimization of high efficiency and high precision in the entire water collection process.
