Description

Technical Field

[0001] This invention relates to the field of intelligent valve technology, specifically to remotely controlled intelligent valves and their control methods. Background Technology

[0002] Intelligent valves are valves with powerful computing capabilities, incorporating a microprocessor within the actuator or valve itself. They transmit relevant information bidirectionally via digital communication and networks, such as valve opening degree, number of actions, action speed, and output torque. They can also remotely set the valve's opening range, change valve characteristics, adjust dead zone, and perform remote calibration. Traditional intelligent valves used for farmland irrigation generally still have a manual adjustment function. However, due to the low frequency of manual adjustment, the adjustment dial often becomes stuck during manual adjustment. Therefore, this paper proposes a remote-controlled intelligent valve and its control method to address these issues. Summary of the Invention

[0003] The purpose of this invention is to provide a remote-controlled intelligent valve and its control method, in order to solve the problem that traditional intelligent valves generally still have a manual adjustment function during use. However, due to the low frequency of manual adjustment, the adjustment dial often becomes stuck during the manual adjustment process.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A remote-controlled intelligent valve and its control method include a valve body, a housing, and a pressure sensor. A partition plate is fixedly connected to the inner side of the housing. A backup power supply is fixedly connected to the inner side of the left end face of the housing. A main control module and a real-time environmental monitoring module are fixedly connected to the inner side of the rear end face of the housing. One end of a connecting pipe is detachably connected to both ends of the valve body, and a flange is fixedly connected to the other end of the connecting pipe. A limit block is fixedly connected to the upper end face of the valve body, and an adjusting screw is screwed to the inner side of the limit block. One end of the adjusting screw passes through the valve body and is fixed in place. A valve core is connected to the valve body. A turntable is fixedly connected to the upper outer side of the adjusting screw. The turntable is located outside the valve body. A groove perpendicular to the extension direction of the adjusting screw is opened on the inner side of the turntable. One end of a compression spring is symmetrically fixedly connected to the inner side of the groove near the center. The other end of the compression spring is fixedly connected to a telescopic rod. The outer side of the telescopic rod is slidably connected to the groove. A slot is opened on the upper part of the telescopic rod. One end of a locking rod is engaged on the inner side of the slot. The other end of the locking rod extends out of the groove. The outer side of the locking rod is slidably connected to the turntable.

[0006] Preferably, an adjusting motor is fixedly connected to the inner side of the lower end face of the chassis, the end of the main shaft of the adjusting motor is fixedly connected to the other end of the adjusting screw, an operating block is fixedly connected to the other end of the clamping rod, one end of a tension spring is fixedly connected to the outer side of the operating block, the other end of the tension spring is fixedly connected to the upper end face of the turntable, and the lower end face of the clamping rod is inclined at an angle of 30 degrees.

[0007] Preferably, the upper part of the chassis is hinged to a top cover, the lower end face of the top cover is fixedly connected to a housing, the lower end face of the housing is fixedly connected to a pressure sensor, the upper end face of the pressure sensor is attached to a holding plate, the upper end face of the holding plate is fixedly connected to an absorbent sponge, and the outer sides of the absorbent sponge and the holding plate are in contact with the top cover and the housing.

[0008] Preferably, a fixing plate is fixedly connected to the outer side of the valve body, one end of a fixing column is fixedly connected to the upper end face of the fixing plate, the other end of the fixing column is fixedly connected to the outer end face of the chassis, the fixing column is arc-shaped, a support leg is fixedly connected to the lower end face of the fixing plate, and a buffer pad is fixedly connected to the lower end face of the support leg, the buffer pad being 3 mm thick.

[0009] Preferably, there are two of each of the slide groove, compression spring, telescopic rod, slot, and rod, and the two slide grooves, compression springs, telescopic rods, slots, and rods are symmetrically distributed on the left and right sides of the turntable's central axis.

[0010] Preferably, the main control module integrates a signal interaction module, a potential detection module, a two-way signal transceiver module, a device main control module, a data processing module, and a wireless communication module on its inner side. The device main control module integrates a valve control module, an energy-saving power supply module, and a backup power supply module on its inner side. The real-time environmental monitoring module integrates an air temperature detection module and an air humidity detection module on its inner side.

[0011] Preferred configuration: When the air humidity detection module detects low humidity during operation, the main control module activates the regulating motor in the valve control module within the main control module. This motor rotates and drives the regulating screw, effectively controlling the flow rate through the rotation of the valve core within the valve body. When it rains during operation, the absorbent sponge absorbs water and becomes heavier, causing the holding plate to move downwards. This applies pressure to the pressure sensor, which detects the electrical signal. The potential detection module then controls the valve control module via the main control module. When the control motor reverses, it drives the valve core to close the valve body via the adjusting screw. When external technicians need to check the opening and closing status of the valve core inside the valve body, they can do so via the wireless communication module inside the main control module. In case of power failure or special circumstances requiring manual operation of the valve body's opening and closing, hold the turntable and rotate the adjusting screw. If the turntable cannot rotate, pull the operating block and pull the locking rod upwards to disengage it from the locking slot. At this time, the telescopic rod will slide outwards under the elastic potential energy of the compressed spring, and then the operator can use the extended telescopic rod to rotate the turntable.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. In this invention, by setting a limiting block, adjusting screw, turntable, slide groove, compression spring, telescopic rod, slot and lever, the turntable can be easily rotated when it cannot rotate by using the extension of the telescopic rod through the engagement and disengagement of the lever and slot. This solves the problem that traditional intelligent valves generally have a manual adjustment function, but due to the low frequency of manual adjustment, the adjustment turntable often cannot be turned during the manual adjustment process.

[0014] 2. In this invention, by using the housing, pressure sensor, holding plate, and water-absorbing sponge, the principle that the water-absorbing sponge becomes heavier after absorbing water and will cause the holding plate to apply pressure to the pressure sensor can be utilized. This allows the valve to be closed in time when irrigation is not needed, reducing water waste and having good promotional value.

[0015] 3. In this invention, by setting up a signal interaction module, a data processing module, a wireless communication module, a main equipment control module, a valve control module, and a general control module, the built-in modules can realize timely data transmission and real-time monitoring of equipment usage status, thereby improving the intelligence and automation of the overall device.

Detailed Implementation

[0022] Example 1:

[0023] Please see Figure 1-5 The present invention provides a technical solution:

[0024] A remote-controlled intelligent valve and its control method include a valve body 1, a housing 2, and a pressure sensor 18. A partition plate 25 is fixedly connected to the inner side of the housing 2. A backup power supply 26 is fixedly connected to the inner side of the left end face of the housing 2. A main control module 27 and a real-time environmental monitoring module 28 are fixedly connected to the inner side of the rear end face of the housing 2. One end of a connecting pipe 3 is detachably connected to both ends of the valve body 1, and a flange 4 is fixedly connected to the other end of the connecting pipe 3. A limit block 5 is fixedly connected to the upper end face of the valve body 1. An adjusting screw 6 is screwed to the inner side of the limit block 5. One end of the adjusting screw 6 passes through the valve body 1 and is fixedly connected to a valve core. A turntable 7 is fixedly connected to the upper outer side of the adjusting screw 6. The turntable 7 is located outside the valve body 1, and an opening is formed on the inner side of the turntable 7 that corresponds to the adjusting screw. A vertically extending groove 8 extends from rod 6. A compression spring 9 is symmetrically fixed to one end of the inner side of the groove 8 near its center. A telescopic rod 10 is fixedly connected to the other end of the compression spring 9. The outer side of the telescopic rod 10 is slidably connected to the groove 8. A slot 11 is provided at the upper part of the telescopic rod 10. One end of a locking rod 12 is engaged with the inner side of the slot 11. The other end of the locking rod 12 extends out of the groove 8. The outer side of the locking rod 12 is slidably connected to the turntable 7. This allows the turntable 7 to be easily rotated when it cannot rotate due to the extension of the telescopic rod 10, solving the problem that traditional intelligent valves generally have a manual adjustment function, but the frequency of manual adjustment is limited. The adjustment is relatively low, and during manual adjustment, the adjustment turntable 7 often becomes stuck. An adjustment motor 13 is fixedly connected to the inner side of the lower end face of the housing 2. The end of the main shaft of the adjustment motor 13 is fixedly connected to the other end of the adjustment screw 6. An operating block 14 is fixedly connected to the other end of the locking rod 12. One end of a tension spring 15 is fixedly connected to the outer side of the operating block 14. The other end of the tension spring 15 is fixedly connected to the upper end face of the turntable 7. The lower end face of the locking rod 12 is inclined at an angle of 30 degrees to facilitate the retraction and reset of the telescopic rod 10. A fixing plate 21 is fixedly connected to the outer side of the valve body 1. One end of a fixing post 22 is fixedly connected to the upper end face of the fixing plate 21. The other end of the fixing post 22 is connected to the housing 2. The outer end face is fixedly connected, and the fixed column 22 is arc-shaped. The lower end face of the fixed plate 21 is fixedly connected to the support leg 23, and the lower end face of the support leg 23 is fixedly connected to the buffer pad 24. The buffer pad 24 is 3 mm thick, which can make the operation of the whole device more stable. There are two of each of the slide groove 8, compression spring 9, telescopic rod 10, slot 11, and locking rod 12. The two slide grooves 8, compression springs 9, telescopic rods 10, slots 11, and locking rods 12 are symmetrically distributed on the left and right sides of the central axis of the turntable 7, which can make the force on the whole device more balanced. The inner side of the main control module 27 integrates a signal interaction module, a potential detection module, a two-way signal transceiver module, a main control module, a data processing module, and a wireless communication module.The main control module integrates a valve control module, an energy-saving power supply module, and a backup power supply module. The real-time environmental monitoring module 28 integrates an air temperature detection module and an air humidity detection module. This allows for timely data transmission and real-time monitoring of the equipment's operating status, improving the overall intelligence and automation of the device. When the air humidity detection module detects low humidity during operation, the main control module 27 controls the valve control module within the main control module to start the regulating motor 13. This motor 13 rotates, driving the regulating screw 6 to rotate, thereby controlling the rotation of the valve core inside the valve body 1. The flow rate of valve body 1 is effectively controlled. When external technicians need to understand the opening and closing status of the valve core inside valve body 1, they can view the information through the wireless communication module inside the main control module 27. In case of power failure or special circumstances requiring manual operation of valve body 1, the operator holds the turntable 7 and rotates the adjusting screw 6. If the turntable 7 cannot rotate, the operator pulls the operating block 14, pulling upwards the locking rod 12 to disengage it from the locking slot 11. At this point, the telescopic rod 10 will slide outwards under the elastic potential energy of the compression spring 9. The operator can then use the extended telescopic rod 10 to rotate the turntable 7.

[0025] Example 2:

[0026] Please see Figure 1-5 The present invention provides a technical solution:

[0027] A remote-controlled intelligent valve and its control method include a valve body 1, a housing 2, and a pressure sensor 18. A partition plate 25 is fixedly connected to the inner side of the housing 2. A backup power supply 26 is fixedly connected to the inner side of the left end face of the housing 2. A main control module 27 and a real-time environmental monitoring module 28 are fixedly connected to the inner side of the rear end face of the housing 2. One end of a connecting pipe 3 is detachably connected to both ends of the valve body 1, and a flange 4 is fixedly connected to the other end of the connecting pipe 3. A limit block 5 is fixedly connected to the upper end face of the valve body 1. An adjusting screw 6 is screwed to the inner side of the limit block 5. One end of the adjusting screw 6 passes through the valve body 1 and is fixedly connected to a valve core. A turntable 7 is fixedly connected to the upper outer side of the adjusting screw 6. The turntable 7 is located outside the valve body 1, and a section perpendicular to the extension direction of the adjusting screw 6 is opened on the inner side of the turntable 7. A straight slide groove 8 has a compression spring 9 symmetrically fixedly connected to one end near the center of its inner side. The other end of the compression spring 9 is fixedly connected to a telescopic rod 10. The outer side of the telescopic rod 10 is slidably connected to the slide groove 8. A slot 11 is provided on the upper part of the telescopic rod 10. One end of a locking rod 12 is engaged with the inner side of the slot 11. The other end of the locking rod 12 extends out of the slide groove 8, and the outer side of the locking rod 12 is slidably connected to the turntable 7. This allows the turntable 7 to be easily rotated when it cannot rotate due to the extension of the telescopic rod 10, solving the problem that traditional intelligent valves generally have a manual adjustment function, but because manual adjustment is infrequent, errors often occur during manual adjustment. When the adjustment turntable 7 cannot rotate, an adjustment motor 13 is fixedly connected to the inner side of the lower end face of the chassis 2. The end of the main shaft of the adjustment motor 13 is fixedly connected to the other end of the adjustment screw 6. An operating block 14 is fixedly connected to the other end of the locking rod 12. One end of a tension spring 15 is fixedly connected to the outer side of the operating block 14. The other end of the tension spring 15 is fixedly connected to the upper end face of the turntable 7. The lower end face of the locking rod 12 is inclined at an angle of 30 degrees to facilitate the retraction and reset of the telescopic rod 10. The upper part of the chassis 2 is hinged to a top cover 16. A housing 17 is fixedly connected to the lower end face of the top cover 16. A pressure sensor 18 is fixedly connected to the inner side of the lower end face of the housing 17. A holding plate 1 is attached to the upper end face of the pressure sensor 18. 9. An absorbent sponge 20 is fixedly connected to the upper surface of the holding plate 19. Both the absorbent sponge 20 and the outer side of the holding plate 19 are in contact with the upper cover 16 and the housing 17. This utilizes the principle that the absorbent sponge 20 absorbs water and becomes heavier, which will cause the holding plate 19 to apply pressure to the pressure sensor 18. This allows the valve body 1 to be closed in time when irrigation is not needed, reducing water waste and having good promotional value. A fixing plate 21 is fixedly connected to the outer side of the valve body 1. One end of a fixing column 22 is fixedly connected to the upper surface of the fixing plate 21. The other end of the fixing column 22 is fixedly connected to the outer end face of the casing 2. The fixing column 22 is arc-shaped. A support leg 23 is fixedly connected to the lower surface of the fixing plate 21. A buffer pad 24 is fixedly connected to the lower surface of the support leg 23.The buffer pad 24 is 3 mm thick, which makes the operation of the entire device more stable. There are two of each of the slide groove 8, compression spring 9, telescopic rod 10, slot 11, and lever 12. The two slide grooves 8, compression springs 9, telescopic rods 10, slots 11, and levers 12 are symmetrically distributed on the left and right sides of the central axis of the turntable 7, which makes the force on the entire device more balanced. The inner side of the main control module 27 integrates a signal interaction module, a potential detection module, a two-way signal transceiver module, a main control module, a data processing module, and a wireless communication module. The inner side of the main control module integrates a valve control module. The device includes a control module, an energy-saving power supply module, and a backup power supply module. The real-time environmental monitoring module 28 integrates an air temperature detection module and an air humidity detection module. These built-in modules enable timely data transmission and real-time monitoring of the equipment's operating status, improving the overall intelligence and automation of the device. When the air humidity detection module detects low humidity during operation, the main control module 27 controls the valve control module within the main control module to start the regulating motor 13 in forward rotation. This motor 13 rotates and drives the regulating screw 6, effectively controlling the flow rate of the valve body 1 by rotating the valve core inside the valve body 1. When it rains during operation, the absorbent sponge 20 absorbs water and becomes heavier, causing the holding plate 19 to move downwards, applying pressure to the pressure sensor 18. The potential detection module detects the electrical signal from the pressure sensor 18, and the main control module 27 controls the valve control module to operate, which in turn controls the regulating motor 13 in reverse rotation. The regulating motor 13 then drives the valve core through the regulating screw 6 to close the valve body 1. When external technicians need to adjust the valve body 1... To check the opening and closing status of the inner valve core, the information can be transmitted and viewed through the wireless communication module inside the main control module 27. In case of power failure or other special circumstances requiring manual operation of the valve body 1, hold the turntable 7 and rotate the adjusting screw 6. If the turntable 7 cannot rotate, pull the operating block 14 to pull the locking rod 12 upwards, disengaging it from the locking groove 11. At this point, the telescopic rod 10 will slide outwards under the elastic potential energy of the compression spring 9. The operator can then use the extended telescopic rod 10 to rotate the turntable 7.
