Description

Technical Field

[0001] The invention relates to the technical field of valve movement smoothness, and in particular to a valve movement smoothness detection system for a valve controller. Background Art

[0002] In water conservancy, valves play a vital role. They are used to control the direction, flow and pressure of water flow to ensure the normal operation of the water conservancy system. The valve controller is a product used in conjunction with the valve electric device. It is mainly used to control the opening and closing of the electric valve and adjust the degree of valve opening and closing. At present, when the valve is used in irrigation, the input end of the valve is connected to the water inlet pipe and the water source, such as the irrigation canal. When the gate in the valve moves, the water at the water source can pass through the valve to irrigate the target area; As the valve is used, debris in the irrigation canal is easy to enter the valve, which can easily affect the normal use of the valve. In order to deal with this problem, the current solution is generally to install a filter at one end of the water inlet pipe located in the irrigation canal to intercept the debris. In order to avoid affecting the efficiency of pumping, the aperture of the filter is designed to be larger. In this case, the silt in the irrigation canal still has the opportunity to enter the valve and affect the descent of the gate plate; In the above description, because the valve casing is generally made of opaque metal and it is inconvenient to judge the internal sediment content in the irrigation canal with the naked eye, it is easy for a large amount of sediment to accumulate in the valve without knowing it, causing the valve to be affected by the sediment and the gate's ability to move gradually decreased. Summary of the invention

[0003] The present invention aims at the technical problems existing in the prior art and provides a valve movement smoothness detection system for a valve controller.

[0004] The technical solution of the present invention to solve the above technical problem is as follows: a valve movement smoothness detection system for a valve controller, the valve movement smoothness detection system for a valve controller comprising: An equipment module, wherein the equipment module comprises a valve controller and a valve, wherein the valve controller comprises a display screen, and the valve comprises a gate; A detection module, the detection module is used to detect the valve, specifically, The detection module continuously monitors the output power P1 of the motor used to move the gate during the movement of the gate in the valve; The detection module continuously obtains the flow rate L1 of water passing through the gate plate when the gate plate in the valve moves and opens; The detection module continuously obtains the amplitude V1 of the valve during the movement of the gate in the valve; An original data module, wherein the original data module is used to store the factory data of the valve; The raw data module obtains the output power P2 of the motor used to move the gate plate in the valve during the movement of the gate plate in the valve when it leaves the factory, and obtains the maximum output power acceptance value P2+20 kilowatts; The raw data module obtains the flow rate L2 of water passing through the gate when the gate moves and opens in the valve at the time of leaving the factory, and obtains the minimum flow rate L2-0.5l / s, wherein it should be noted that it is necessary to ensure that the moving height of the gate at the factory is consistent with the moving height of the gate in use; The raw data module obtains the amplitude V2 of the valve during the movement of the gate in the valve when it leaves the factory, and obtains the maximum amplitude acceptance value V2-1cm; A comparison module is used to compare the original data module with the detection module, specifically, The output power P1 of the motor obtained by the detection module is compared with the maximum output power acceptance value P2+20 kilowatts of the motor obtained by the original data module, and P1≤P2+20 kilowatts; The flow rate L1 of the water flowing through the gate obtained by the detection module is compared with the minimum flow rate L2-0.5l / s of the water flowing through the gate obtained by the original data module, L1≥L2-0.5l / s; The detection module obtains the valve amplitude V1 and compares it with the maximum amplitude acceptance value V2-1cm obtained by the original data module, V1≤V2-1cm; The valve controller is specifically used for: Data obtained by the detection module: When P1≤P2+20kW, L1≥L2-0.5l / s and V1≤V2-1cm, it is judged that the motor output power P1, the flow rate L1 of water passing through the gate and the amplitude value V1 are acceptable, the gate in the valve can continue to move, and the valve can be used normally; When P1≥P2+20kW, L1≤L2-0.5l / s and V1V2-1cm, the three values ​​are compared. If any one of them is the above ratio, it is judged that the motor output power P1, the water flow rate L1 through the gate and the amplitude value V1 are unacceptable, and it is judged that there is a lot of sediment in the gate and it seriously affects the normal use of the valve. The valve controller immediately controls the valve to cut off the power.

[0005] The detection module also includes a recorder installed inside the valve and close to the gate; The equipment module also includes a broadcasting unit, which is used to play the sound generated by the movement of the gate, and the broadcasting unit includes a speaker installed on the valve controller, specifically, During the movement of the gate inside the valve, the recorder records the sound. When the valve is required to leave the factory, the gate is moved to obtain the sound of the normal movement of the gate, which is backed up by the original data module and can be played by the speaker. After the valve is put into use, the sound generated by the movement of the gate is captured by the recorder and played by the speaker; The speaker on the valve controller is used manually to alternately play the normal sound of the gate movement and the sound generated by the gate movement for 5 times, and it is manually judged whether there is an abnormal sound when the gate moves, and then combined with P1, L1 and V1 to further judge the sediment accumulation in the valve.

[0006] The equipment module also includes a timed deletion unit arranged in the valve controller, which is used to regularly delete the recording after the gate is used, specifically, The recorder of the broadcasting unit retains 5 recordings. When the recorder performs the sixth recording, the timing deletion unit deletes the earliest recording in the recorder, so that the recorder always keeps 5 recordings.

[0007] The turbidity acquisition module includes a turbidity sensor installed inside the valve, specifically, The turbidity of the water passing through the valve is obtained by the turbidity sensor and is used as an important indicator for determining the amount of sediment accumulation inside the valve. The turbidity value of the water passing through the valve obtained by the turbidity sensor is obtained by the valve controller.

[0008] The valve controller valve movement smoothness detection system also includes: The air inlet module is used to obtain the air flow through the valve, specifically, The air inlet module obtains the amount of air M passing through the valve per second; If the air flow rate M>0m³ / s, it is known that air has entered the valve, and it can be judged that the flow rate L1 of water flowing through the gate is inaccurate. It is necessary to promptly check whether there is a possibility of air entering between the valve input end and the water source; If the air flow rate = 0m³ / s, it is known that no air enters the valve, and the flow rate L1 of water passing through the gate can be judged to be accurate.

[0009] The air intake module also includes: A first alarm mounted on the valve controller; The timing unit is used to time the duration of air passing through, specifically, When the air flow rate M>0m³ / s appears, the timing starts, and when the air flow rate M=0m³ / s, the timing ends. The time from the start to the end is A; When A>3s, the control switch starts the first alarm. At this time, the first alarm sounds to remind the staff to obtain the air flow M value in time and determine the flow L1 of water passing through the gate; When A≤3s, the switch is not controlled to activate the first alarm.

[0010] The detection module also includes a second alarm installed on the valve controller; The detection module obtains the flow rate Q of water passing through the gate when the gate is closed; When the flow rate of water passing through the gate is Q=0l / s, it is known that the valve is well sealed and the second alarm will not sound; When the flow rate Q of water passing through the gate plate is ≥ 0l / s, it is known that there is a gap between the inside of the valve and the gate plate, and the second alarm sounds.

[0011] The tilt acquisition module is a tilt sensor installed on the gate plate, specifically, The inclination sensor obtains the inclination angle R1 of the gate; When leaving the factory, the correct initial angle R2 of the gate is known by the inclination sensor, and the correct initial angle R2 of the gate is obtained by the original data module, and the maximum gate inclination angle acceptance value R2±0.5 degrees is set; When the gate plate's inclination angle R1≤the gate plate's inclination angle acceptance value R2±0.5 degrees, the gate plate is considered to be in a normal state; When the gate's inclination angle R1>the gate's inclination angle acceptance value R2±0.5 degrees, the valve controller obtains R1>R2±0.5 degrees, which is used by the artificial panel to determine the accuracy of the flow rate Q of water passing through the gate when the gate is closed.

[0012] The beneficial effects of the present invention are: The comparison module compares the values ​​obtained by the original data module with the values ​​obtained by the detection module, and determines whether the output power of the motor used to move the gate, the flow rate of water passing through the gate, and the amplitude of the valve during the movement of the gate are normal values, determines the amount of sediment in the gate and seriously affects the normal use of the valve, and controls the valve to cut off power, so as to achieve the purpose of knowing that the sediment in the valve needs to be cleaned and avoiding the friction between the sediment and the inner wall of the valve and the gate. By obtaining multiple indicators of the smoothness of the movement of the gate inside the valve, it is determined whether the sediment inside the valve needs to be cleaned; Manual intervention is used to determine whether the amount of sediment accumulated in the valve has increased the friction between the gate and the inner wall of the valve to a large extent during the movement of the gate, resulting in abnormal noise. The detection module is used to obtain values ​​to further determine the sediment accumulation in the valve. The turbidity acquisition module obtains the turbidity value of the water passing through the valve, and manually determines whether the turbidity of the water is high based on the actual local conditions, and whether the sediment in the irrigation canal needs to be cleaned to reduce the amount of sediment; The air flow inside the valve is obtained through the air inlet module to determine whether air has entered the valve. At the same time, the timing unit performs timing. When the air flow generation time exceeds the normal time, the alarm sounds to determine that air has entered the valve, which is convenient for the staff to check whether one end of the water inlet pipe connected to the valve input end is completely located in the water of the irrigation canal.

DETAILED DESCRIPTION

[0015] A valve movement smoothness detection system for a valve controller, the valve movement smoothness detection system for a valve controller comprising: An equipment module, wherein the equipment module comprises a valve controller and a valve, wherein the valve controller comprises a display screen, and the valve comprises a gate; A detection module, the detection module is used to detect the valve, specifically, The detection module continuously monitors the output power P1 of the motor used to move the gate during the movement of the gate in the valve; The detection module continuously obtains the flow rate L1 of water passing through the gate plate when the gate plate in the valve moves and opens; The detection module continuously obtains the amplitude V1 of the valve during the movement of the gate in the valve; An original data module, wherein the original data module is used to store the factory data of the valve; The raw data module obtains the output power P2 of the motor used to move the gate plate in the valve during the movement of the gate plate in the valve when it leaves the factory, and obtains the maximum output power acceptance value P2+20 kilowatts; The raw data module obtains the flow rate L2 of water passing through the gate when the gate in the valve moves and opens when leaving the factory, and obtains the minimum flow rate L2-0.5l / s; The raw data module obtains the amplitude V2 of the valve during the movement of the gate in the valve when it leaves the factory, and obtains the maximum amplitude acceptance value V2-1cm; A comparison module is used to compare the original data module with the detection module, specifically, The output power P1 of the motor obtained by the detection module is compared with the maximum output power acceptance value P2+20 kilowatts of the motor obtained by the original data module, and P1≤P2+20 kilowatts; The flow rate L1 of the water flowing through the gate obtained by the detection module is compared with the minimum flow rate L2-0.5l / s of the water flowing through the gate obtained by the original data module, L1≥L2-0.5l / s; The detection module obtains the valve amplitude V1 and compares it with the maximum amplitude acceptance value V2-1cm obtained by the original data module, V1≤V2-1cm; The valve controller is specifically used for: Data obtained by the detection module: When P1≤P2+20kW, L1≥L2-0.5l / s and V1≤V2-1cm, it is judged that the motor output power P1, the flow rate L1 of water passing through the gate and the amplitude value V1 are acceptable, the gate in the valve can continue to move, and the valve can be used normally; When P1≥P2+20kW, L1≤L2-0.5l / s and V1V2-1cm, the three values ​​are compared. If any one of them is the above ratio, it is judged that the motor output power P1, the flow rate L1 of water passing through the gate plate and the amplitude value V1 are unacceptable, and it is judged that there is sediment in the gate plate and it seriously affects the normal use of the valve. The valve controller immediately controls the valve to cut off the power; It should be noted that when the valve is inspected at the factory, specifically: the data collection by the raw data module and the position fixation of the valve when it is put into use, both need to ensure the stability of the valve installation method; In the prior art, the valve housing is generally made of opaque metal material, and it is inconvenient to visually judge the internal sediment content in the irrigation canal, which easily leads to a large amount of sediment accumulating in the valve without knowing it, thus causing the valve to be affected by the sediment and the gate movement ability to gradually decrease; According to the above technical solution, the above problem can be solved. Specifically, when the valve leaves the factory, the original data module obtains P2+20 kW, L2-0.5 l / s and V2-1 cm. When the valve is put into use, each time the gate in the valve moves, P1, L1 and V2 are obtained, and the comparison module compares and judges whether P1, L1 and V2 are normal values. If they are not normal values, it is determined that there is a lot of sediment in the gate and it seriously affects the normal use of the valve. The valve controller immediately controls the valve to cut off the power, so as to achieve the purpose of knowing that the sediment in the valve needs to be cleaned and avoiding the friction of the sediment on the inner wall of the valve and the gate. Among them, l / s (indicates the volume of water flowing per second, l is liter, s is second), cm (centimeter). Example 2

[0016] On the basis of Example 1, the detection module further comprises a recorder installed inside the valve and close to the gate, and the recorder is a PANDA 6107 model; The equipment module also includes a broadcasting unit, which is used to play the sound generated by the movement of the gate, and the broadcasting unit includes a speaker installed on the valve controller. The speaker adopts a 28mm speaker produced by Shenzhen Xingwei Electronics Co., Ltd., specifically, During the movement of the gate inside the valve, the recorder records the sound. When the valve is required to leave the factory, the gate is moved to obtain the sound of the normal movement of the gate, which is backed up by the original data module and can be played by the speaker. After the valve is put into use, the sound generated by the movement of the gate is captured by the recorder and played by the speaker; The speaker on the valve controller is used to play the normal sound of the gate movement and the sound generated by the gate movement alternately for 5 times, and the person is asked to judge whether there is an abnormal sound when the gate moves, and then further judge the sediment accumulation in the valve by combining P1, L1 and V1; The equipment module also includes a timed deletion unit arranged in the valve controller, which is used to regularly delete the recording after the gate is used, specifically, The recorder of the broadcasting unit retains 5 recordings, and when the recorder performs the sixth recording, the timing deletion unit deletes the earliest recording in the recorder, so that the recorder always retains 5 recordings; According to the above technical solution, manual intervention is used to determine whether the amount of sediment accumulated in the valve has greatly increased the friction between the gate and the inner wall of the valve during the movement of the gate, thereby generating abnormal noise. By determining the sediment accumulation in the valve, the next step of processing can be performed, for example, cleaning the sediment inside the valve. Example 3

[0017] On the basis of Example 1, the turbidity obtaining module includes a turbidity sensor installed inside the valve, specifically, The turbidity of the water passing through the valve is obtained by the turbidity sensor, which is used as an important indicator for determining the amount of sediment accumulation inside the valve. The turbidity value of the water passing through the valve obtained by the turbidity sensor is obtained by the valve controller; The turbidity value of the water is used to determine the amount of sediment (floating state) in the irrigation canal during water pumping. Specifically, The turbidity value Y of the water passing through the valve is obtained, and it is manually determined based on the local actual situation and in combination with the "Agricultural Irrigation Water Quality Standard" (GB 5084-2021) to determine whether the water turbidity is high. It is necessary to clean the sediment in the irrigation channel to reduce the amount of sediment. Example 4

[0018] Based on Example 1, the valve controller valve movement smoothness detection system further includes: The air inlet module is used to obtain the air flow through the valve, specifically, The air inlet module obtains the amount of air M passing through the valve per second; If the air flow rate M>0m³ / s, it is known that air has entered the valve, and it can be judged that the flow rate L1 of water passing through the gate is inaccurate, so it is necessary to promptly check whether there is a possibility of air entering between the valve input end and the water source; If the air flow rate = 0m³ / s, it is known that no air enters the valve, and the flow rate L1 of water passing through the gate can be judged to be accurate; The air intake module also includes: A first alarm installed on the valve controller, the specific model of the first alarm is SONITRON alarm SMAC-25; The timing unit is used to time the duration of air passing through, specifically, When the air flow rate M>0m³ / s appears, the timing starts, and when the air flow rate M=0m³ / s, the timing ends. The time from the start to the end is A; When A>3s, the control switch starts the first alarm. At this time, the first alarm sounds, reminding the staff to obtain the air flow M value in time and determine the flow L1 of water passing through the gate; When A≤3s, the switch is not controlled to start the first alarm; According to the above technical solution, the air inlet module obtains the air flow rate inside the valve, which is used to determine whether air has entered the valve. If air has entered the valve, there is reason to believe that the flow rate of water passing through the gate obtained by the detection module is inaccurate. In this case, the interception valve stops operating, allowing the valve to continue to operate normally, and allowing the detection module to continue to obtain the flow rate of water passing through the gate for a comparison. At the same time, the timing unit performs timing, and when the air flow generation time exceeds the existing normal time, the first alarm sounds to determine that air has entered the valve, which is convenient for the staff to check whether one end of the water inlet pipe connected to the valve input end is completely located in the water in the irrigation canal. Example 5

[0019] On the basis of Example 1, the detection module further includes a second alarm installed on the valve controller, and the specific model of the second alarm is SONITRON alarm SMAC-25; The detection module obtains the flow rate Q of water passing through the gate when the gate is closed; When the flow rate of water passing through the gate is Q=0l / s, it is known that the valve is well sealed and the second alarm will not sound; When the flow rate Q of water passing through the gate plate is ≥ 0l / s, it is known that there is a gap between the inside of the valve and the gate plate, and the second alarm sounds; The tilt acquisition module is a tilt sensor installed on the gate plate, specifically, The inclination sensor obtains the inclination angle R1 of the gate; When leaving the factory, the correct initial angle R2 of the gate is known by the inclination sensor, and the correct initial angle R2 of the gate is obtained by the original data module, and the maximum gate inclination angle acceptance value R2±0.5 degrees is set; When the gate plate's inclination angle R1≤the gate plate's inclination angle acceptance value R2±0.5 degrees, the gate plate is considered to be in a normal state; When the gate's inclination angle R1> gate's inclination angle acceptance value R2±0.5 degrees, the valve controller obtains R1>R2±0.5 degrees, which is used by the artificial plate to determine the accuracy of the flow rate Q of water passing through the gate when the gate is closed; According to the above technical scheme, specifically, the flow rate of water passing through the gate plate when the gate plate is closed is obtained to determine whether there is a gap between the valve and the internal gate plate and water leakage, which is used to know whether the accumulation of sediment in the valve has caused wear inside the valve and requires emergency repair. At the same time, the inclination angle of the gate plate is obtained to know whether the gate plate is deformed by the influence of water pressure. If the degree of deformation of the gate plate exceeds the normal range, there is reason to judge that the water flow through the gate plate when the gate plate is closed is not caused by sediment, and it can be determined whether the sediment in the irrigation canal needs to be cleaned.

[0020] Working principle: When the valve leaves the factory, the original data module obtains P2+20 kW, L2-0.5 l / s and V2-1 cm. When the valve is put into use, each time the gate inside the valve moves, P1, L1 and V2 are obtained, and the comparison module compares and determines whether P1, L1 and V2 are normal values. If they are not normal values, it is determined that there is a lot of sediment in the gate and it seriously affects the normal use of the valve. The valve controller immediately controls the valve to cut off power, so as to achieve the purpose of knowing that the sediment in the valve needs to be cleaned and avoiding the friction between the sediment and the inner wall of the valve and the gate. By obtaining multiple indicators of the smoothness of the movement of the gate inside the valve, it is determined whether the sediment inside the valve needs to be cleaned.

[0021] Human intervention is used to determine whether the amount of sediment accumulated in the valve has greatly increased the friction between the gate and the inner wall of the valve during the movement of the gate, resulting in abnormal noise. The sediment accumulation in the valve can be determined and the next step can be taken, such as cleaning the sediment inside the valve.

[0022] The turbidity value of the water passing through the valve is obtained, and it is manually determined based on the local actual situation whether the turbidity of the water is high and whether the sediment in the irrigation channel needs to be cleaned to reduce the amount of sediment.

[0023] The air inlet module obtains the air flow rate inside the valve, which is used to determine whether air has entered the valve. If air has entered the valve, there is reason to believe that the water flow rate through the gate obtained by the detection module is inaccurate. In this case, the interception valve stops operating, allowing the valve to continue to operate normally, and the detection module continues to obtain the water flow rate through the gate for a comparison. At the same time, the timing unit starts timing, and when the air flow generation time exceeds the normal time, the alarm sounds to determine that air has entered the valve, which is convenient for the staff to check whether one end of the water inlet pipe connected to the valve input end is completely located in the water of the irrigation canal.

[0024] The valve controller uses a valve movement smoothness detection system to obtain the flow rate of water passing through the gate when the gate is closed to determine whether there is a gap between the valve and the internal gate and water leakage. It is used to know whether the accumulation of sediment in the valve has caused wear inside the valve and requires emergency repair. At the same time, the inclination angle of the gate is obtained to know whether the gate is deformed by the water pressure. If the deformation of the gate exceeds the normal range, there is reason to judge that the water flow through the gate when the gate is closed is not caused by sediment, and it can be determined whether the sediment in the irrigation canal needs to be cleaned.
