Abstract
Description
Technical Field
[0001] This invention relates to the field of valve operating status detection technology, and specifically to a valve operating status detection communication system. Background Technology
[0002] In agricultural irrigation, valves are the core equipment for controlling irrigation water usage, and their working status directly determines the safe operation, energy consumption, and production efficiency of the entire irrigation system. Currently, the detection of valve working status mainly relies on manual inspection, with maintenance personnel periodically visiting the site to check the appearance and operating status of the valves and collecting some parameters using portable devices. However, this traditional inspection method has significant drawbacks: First, the fixed intervals of manual inspections make real-time monitoring impossible. When valves experience sudden malfunctions, such as leaks, they are difficult to detect in time, potentially leading to safety accidents, economic losses, and environmental pollution. Second, manually collected data is susceptible to human error, and data recording relies heavily on paper or simple electronic documents, making unified data management and traceability difficult. Furthermore, manual inspections are challenging and costly for valves in complex farmland environments.
[0003] With the development of industrial intelligence and based on the needs of large-scale planting in modern agriculture, some existing monitoring equipment can automatically detect the three major parameters of valve flow, pressure and temperature. However, for the pressure detection of valve inlet and outlet, the two pressure detectors work independently and collect data independently. Once the pressure difference exceeds the limit, it is not possible to better determine whether it is due to a problem with the pressure detection instrument, and there is a lack of a verification mechanism for correlation and reference judgment.
[0004] Regarding flow detection for valves, on the one hand, the principles for calculating flow are diverse, including velocity-based and volumetric flow-based methods, and the methods and principles for converting and calculating flow data are not standardized, thus lacking the function of adjusting the accuracy of flow conversion calculation. On the other hand, commonly used flow meters, based on different pipelines and different irrigation needs, require a more universal form of data display and transmission. Furthermore, different accuracy classes, such as the common 0.2 class, 0.5 class, or even multiple class flow meters, are required for installation and use, which increases the difficulty of rapid and efficient flow detection and lacks universality. Summary of the Invention
[0005] In view of this, the purpose of the present invention is to provide a valve working status detection communication system to solve the problem that in the prior art, when detecting pressure and flow of valves, it is difficult to balance accuracy and versatility, and there is a lack of an automatic verification mechanism for the correlation of working status parameters.
[0006] This invention is achieved through the following technical solution: A valve working status detection and communication system includes a detection terminal, a communication module, a cloud server, and a user terminal. The detection terminal is connected to the valve and transmits the collected working status data to the cloud server through the communication module, so as to send an early warning signal to the user terminal when abnormal parameters are detected. The detection terminal includes a pressure detection unit and a flow detection unit; The pressure detection unit includes a first pressure tapping pipe and a second pressure tapping pipe installed at the valve inlet and outlet ends. Both pressure tapping pipes are equipped with pistons in a dynamically sealed manner. The pistons are connected to a pressure sensing element sealed in the mounting base through an elastic telescopic rod that extends into the mounting base via a sliding seal, so as to reflect the pressure at the two ends of the valve respectively. A horizontal pipe is connected between the top ends of two adjacent pressure tapping pipes. A slider is horizontally slidably installed inside the horizontal pipe. The slider is positioned opposite to a distance sensor on one side of the horizontal pipe. The slider is connected to the hole between the piston and the mounting seat inside the pressure tapping pipe so as to represent the pressure difference between the valve inlet and outlet with the detection value of the distance sensor. The flow detection unit includes a mounting plate installed at the end of the rotor shaft. Several slide rods are arranged in a ring on the mounting plate. A signal element is provided at the end of the slide rod that extends out of the mounting plate. A signal receiver is provided on the inner wall of the metering cover above the signal element. When the mounting plate rotates, the signal element and the signal receiver face each other to generate a signal, so as to represent the flow rate as a signal number. If the cloud server detects that the distance sensor's detection value or the number of signals per unit time exceeds the corresponding value, it will push an alarm message to the user terminal. Furthermore, a support ring is threadedly fixed at the bottom end of each pressure tapping tube, and the support ring is used to support the piston.
[0007] Furthermore, the horizontal pipe is connected to the top of the two pressure tapping pipes via a right-angle bend, and the horizontal pipe is located behind the valve.
[0008] Furthermore, the slide bar is slidably mounted on the end of the mounting plate opposite to the rotor shaft, and is slidably mounted along the radial direction of the mounting plate.
[0009] Furthermore, the surface of the slide bar exposed on the mounting plate is provided with a planar thread, and an adjustment cup is provided above the slide bar that can rotate coaxially with the mounting plate. The bottom port of the adjustment cup is driven by the slide bar through the planar thread so that all slide bars slide synchronously.
[0010] Furthermore, the top of the adjusting cup is closed and the bottom is open. The closed end has a shaft hole in the center. A spindle is coaxially fixed in the center of the mounting plate. The spindle rotates with the shaft hole to realize the rotation of the adjusting cup relative to the mounting plate. The end of the spindle that protrudes from the closed end has a thread to cooperate with a locking nut to fix the adjusting cup and the mounting plate together.
[0011] Furthermore, the closed end of the adjusting cup extends downwards to form an elongated sleeve to create the shaft hole, and has a positioning shoulder on the mandrel for contact and positioning with the end face of the elongated sleeve.
[0012] Furthermore, a pressure-bearing spring washer is provided between the locking nut and the end face of the closed end.
[0013] Furthermore, the signal receiver is slidably installed along the radial direction of the metering cover of the flow meter. The metering cover is coaxial with the mounting plate. A threaded sleeve is threaded onto the outside of the signal receiver. When the threaded sleeve is screwed out, it can be inserted into the slot on the mounting post at the end of the slide rod for installing the signal receiver, and coaxially cover the outside of the signal receiver. After the slide rod slides into place, the signal receiver is fixed first, and then the threaded sleeve is screwed into the signal receiver.
[0014] Furthermore, two limiting rods are fixed on the inner wall of the metering cover. Both limiting rods include a stud and a limiting element threaded onto the stud. When the upper limiting element of the upper limiting rod is screwed out, it can prevent the mounting post from rotating. When it contacts the mounting post, the signal element inside the mounting post is coaxially aligned with the signal receiver. When the lower limiting element of the lower limiting rod is screwed out, it can press against the side of the mounting plate radially to fix the mounting plate.
[0015] The beneficial effects of this invention are as follows: This valve operating status detection and communication system employs pressure detection from two aspects. Besides the original direct detection of pressure at the valve's inlet and outlet, it incorporates a special design that adds a pressure-linked control detection element at both ends, based on the pressure detection structure itself. Two pressure taps at the valve's inlet and outlet are used to detect the corresponding pressures. Simultaneously, based on the special structural design of the pressure sensing unit, and in conjunction with a slider inside the horizontal tube, the pressure difference between the valve's two ends is represented by the slider's position, i.e., the detection value of the distance sensor. The cloud server can not only obtain the pressure difference by subtracting the detection values from the pressure sensing elements of the two pressure taps, but also verify the accuracy of this pressure difference using the slider's position, i.e., the aforementioned detection value. These two methods mutually corroborate each other, intuitively representing the pressure state at the valve's inlet and outlet, rather than being limited to the traditional method of simply detecting the actual pressure value.
[0016] In addition, the flow detection unit can represent flow changes in the form of the number of signals. If needed, the specific flow can also be calculated through adaptive conversion of the number of signals. Furthermore, the detection accuracy can be flexibly adjusted according to different flow rates and valve sizes, thus expanding the scope of application.

The objectives and other advantages of the invention can be realized and obtained through the following description. Attached Figure Description

Detailed Implementation
[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0021] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.
[0022] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0023] Please see Figures 1-2 This invention provides a technical solution: a valve operating status detection and communication system. Similar to existing valve operating status detection and communication devices, it includes a detection terminal, a communication module, a cloud server, and a user terminal. The detection terminal is connected to valve 1, and the communication module transmits collected operating status data, such as valve 1 pressure, flow rate, and temperature, to the cloud server. This allows the cloud server to immediately send a warning signal to the user terminal upon detecting abnormal parameters. In this embodiment, the detection terminal includes at least a pressure detection unit and a flow rate detection unit to detect the pressure and flow rate of valve 1, respectively. Specifically, this pressure detection unit includes a first pressure tapping pipe (2 lines) installed at the inlet end of valve 1 and a second pressure tapping pipe (3 lines) installed at the outlet end. Ideally, the two pressure tapping pipes should be installed vertically along the radial direction of the inlet and outlet ends of valve 1. A piston (6) is dynamically sealed within each pressure tapping pipe. The piston (6) is connected to a pressure sensing element (7) sealed within the mounting base (13) via a sliding seal extending into the mounting base (13). When water flows through valve 1, the water pressure pushes the piston (6) upwards, squeezing the elastic telescopic rod (5). The elastic telescopic rod (5) then squeezes the pressure sensing element (7), yielding the corresponding pressure. This allows for the determination of whether the pressure at both ends of valve 1 meets the operating requirements. Furthermore, the two pressure values can be used to determine if valve 1 has issues such as blockage, leading to an excessive pressure difference between the two ends. Besides directly comparing the values from the two pressure sensing elements (7), further details can be found in the [link to relevant documentation]. Figures 1-2Furthermore, a horizontal pipe 4, communicating with both pressure tapping pipes, can be connected between the top ends of two adjacent pressure tapping pipes. The horizontal pipe 4 is horizontally positioned, and a slider 8 is horizontally slidably installed inside it. The slider 8 completely isolates the left and right sections of the horizontal pipe 4, effectively creating a sliding hole dynamic seal within the horizontal pipe 4. This prevents the transparent liquids, such as water or oil, injected into the horizontal pipe 4 from mixing. Simultaneously, a distance sensor 9 is installed on one side of the slider 8 within the horizontal pipe 4. The distance sensor 9 is positioned opposite the slider 8 to detect the distance to it, thereby monitoring changes in the slider 8's position. Specifically, it is also necessary to connect the slider 8 with the hole between the piston 6 in the pressure tapping tube and the mounting base 13. This ensures that, in the case of left-inlet and right-outlet water pressure at the two ports of valve 1, the water pressure at the left end is lower. This lower pressure at the outlet causes the piston 6 in the pressure tapping tube at the inlet to move upwards more than the piston 6 at the outlet. Consequently, the piston 6, through the transparent liquid, deflects the slider 8 to the right. When the pressure difference between the two ends increases, the slider 8 deflects further to the right. If this deflection exceeds a predetermined position, it indicates that the pressure difference is out of range, potentially indicating blockage or leakage in valve 1. In the above embodiment, the offset of the slider 8 is used to indirectly represent the pressure difference between the inlet and outlet of valve 1 as the detection value of the distance sensor 9, and this data is transmitted and analyzed.
[0024] On the other hand, the flow detection unit in this embodiment, such as Figure 1 and Figures 3-4 The main components include a mounting plate 16 installed at the end of the rotor shaft 15. Several sliding rods 17 are arranged in a circular array on the mounting plate 16, each extending beyond one end of the mounting plate 16. Each sliding rod 17 has a signal element 18, and the inner wall of the metering cover 12 above the signal element 18 has a signal receiver 19. When the mounting plate 16 rotates, the signal element 18 and the signal receiver 19 face each other, generating a signal to represent the flow rate as a signal number. In practice, the signal element 18 and the signal receiver 19 can have various implementations. For example, the signal element 18 can be a small cylindrical magnet, while the signal receiver 19 can be a sensor that detects changes in electrical signal when the magnet faces it, generating pulse signals, etc. Alternatively, the signal element 18 can be a specially designed marker block, and the signal receiver 19 can be a sensing element that can identify the marker block. When the marker block rotates to be under this sensing element, a signal is generated. This marker block can have a surface coated with a certain color, and the sensing element can only recognize this color. Alternatively, the signal element 18 and the signal receiver 19 can be a laser transmitter and a laser receiver, respectively. When they are facing each other, the laser receiver receives a laser signal. Other existing methods similar to the above-mentioned technical means can also be used to generate a signal, which corresponds to the rotational speed of the mounting plate 16, that is, the rotational speed of the rotor, and reflects the flow rate.
[0025] Based on the aforementioned hardware, in actual operation, for data transmission and status analysis, if the cloud server detects that the detection value of the distance sensor 9, or the number of signals per unit time, exceeds the corresponding value, it will push alarm information to the user terminal through the communication module. In this embodiment: as Figure 2 In each pressure tapping tube, near its bottom end, a support ring 10 is threadedly fixed. The support ring 10 supports the piston 6, and adjusting its position changes the degree of compression of the elastic telescopic rod 5, thereby adjusting the base value of the pressure change of the valve 1. For example, to operate the valve 1 at a higher pressure, the support ring 10 can be screwed further upwards. In the above embodiment, to accommodate a large valve 1, such as... Figure 10 The horizontal pipe 4 can be connected to the top of the two pressure tapping pipes through the right-angle bend 14, and the horizontal pipe 4 is located behind the valve 1 to avoid the valve 1 being too large, which would cause the vertical length of the two pressure tapping pipes to be too long.
[0026] In this embodiment: as Figure 3 ,as well as Figures 5-6 The slide rod 17 is slidably installed on the end of the mounting plate 16 away from the rotor shaft 15, and is slidably installed along the radial direction of the mounting plate 16. This allows it to adapt to different valves 1 pipelines, that is, to the flow monitoring of flow meters 11 of different sizes. It avoids the phenomenon of "small meter with large head" that often occurs in traditional detection equipment, making this part of the detection element universal across specifications, which is very important for the operation and maintenance of a large number of valves 1. However, the most important and crucial function of the above design structure is actually to adjust the measurement accuracy. Generally speaking, the larger the spacing of these signal elements 18 in a circular array, the greater the spatial distance between them and the pre-positioned signal receiver 19. Even if the rotor of the flow meter 11 rotates at high speed, each signal element 18 will only generate one signal. However, if the radius of the circular array of these signal elements 18 is smaller, the spacing between the signal elements 18 will be smaller, which can easily cause false detection when the rotor rotates at high speed. For example, the signal receiver 19 may not have time to react, resulting in two signal elements 18 passing directly below the signal receiver 19 but only generating one signal. Moreover, because the spacing between the signal elements 18 is too small, there are also requirements for the size of the signal elements 18 and the signal receiver 19 to avoid the signal receiver 19 being installed to correspond to two signal elements 18, which would lead to errors in the detection data. In other words, it has limitations on the structural size of the flow meter 11. Therefore, for example, for a flow meter 11 with a large flow rate and high rotation speed, it is necessary to further increase the spacing between these signal elements 18, that is, all slide rods 17 need to extend further outward from the mounting plate 16. Therefore, by using the above-described method for generating, transmitting, and analyzing flow signals, the flow rate of valve 1 can be effectively detected.
[0027] In this embodiment: To achieve synchronous movement of all slide bars 17, this embodiment introduces a structure, please refer to... Figures 4-6 A planar thread is provided on the surface of the slide rod 17 that is exposed on the mounting plate 16. An adjustment cup 20 is provided above the slide rod 17 that can rotate coaxially with the mounting plate 16. The adjustment cup 20 is cup-shaped with its opening facing the same direction. The bottom port of the adjustment cup 20 is driven by the planar thread to make all slide rods 17 slide synchronously.
[0028] In this embodiment: as Figures 5-7 The adjusting cup 20 is closed at the top and open at the bottom, forming a cup opening. A shaft hole is located in the center of the closed end. A spindle 21 is coaxially fixed to the center of the mounting plate 16. This spindle 21 rotatably engages with the shaft hole to allow the adjusting cup 20 to rotate relative to the mounting plate 16. Furthermore, the end of the spindle 21 exposed above the closed end has a thread to engage with a locking nut 22, allowing the adjusting cup 20 and the mounting plate 16 to be fixed together when needed, preventing the slide rod 17 from moving and ensuring the relative positions of all signal components 18 are fixed. During manufacturing, if... Figure 7 Alternatively, the closed end of the adjusting cup 20 can be extended downwards to form an elongated sleeve 25, creating the shaft hole. A mandrel 21 is inserted into the elongated sleeve 25, and a positioning shoulder 24 is provided on the mandrel 21 for contact and positioning with the end face of the elongated sleeve 25, ensuring the adjusting cup 20 is properly installed on the mounting plate 16. Loosening the locking nut 22 allows the adjusting cup 20 to rotate on the mounting plate 16, driving all the sliding rods 17 to slide synchronously. Once in position, the locking nut 22 is tightened to maintain the extended posture of all the sliding rods 17. To prevent excessive loosening of the locking nut 22, which could cause the adjusting cup 20 to become too loose and difficult to rotate stably, a pressure-bearing spring washer 23 can be provided between the locking nut 22 and the end face of the closed end. This allows the adjusting cup 20 to rotate with appropriate flexibility on the end face of the mounting plate 16 when the locking nut 22 is loosened, making it easy to control.
[0029] In this embodiment: as a very effective design, such as Figure 3 - As shown in example 4, the signal receiver 19 is slidably installed along the radial direction of the metering cover 12 of the flowmeter 11, for example, by sampling T-shaped grooves and T-bolts. After sliding into place, the signal receiver 19 can be fixed in the corresponding position by the T-bolts. Specifically, the metering cover 12 is coaxially arranged with the mounting plate 16, and a threaded sleeve 26 is threaded onto the external thread of the signal receiver 19. When this threaded sleeve 26 is unscrewed, it can be inserted into the end of the slide rod 17, such as... Figures 5-6 ,as well as Figure 8As shown in the slot 170101, this slot 170101 is located on the mounting post 1701 for mounting the signal element 18. The mounting post 1701 is located at the shortest part of the slide rod 17, thus coaxially covering the outside of the signal element 18. Then, the adjusting cup 20 is rotated to move the slide rod 17. During this process, the threaded sleeve 26 and the signal receiver 19 also move synchronously to ensure that the signal receiver 19 can always be vertically aligned with the signal element 18. After the slide rod 17 slides into place, the signal receiver 19 is first fixed by the T-bolt, and then the threaded sleeve 26 is screwed into the signal receiver 19 to disconnect it from the corresponding slide rod 17.
[0030] In this embodiment: to facilitate the adjustment of the signal element 18 and prevent accidental rotation of the mounting plate 16 and adjusting cup 20 during operation, it can be done as follows: Figures 3-4 On the inner wall of the measuring cover 12, two limiting rods are fixed, including an upper limiting rod 27 and a lower limiting rod 28. Both limiting rods include studs and limiting elements threaded onto the studs, such as... Figure 3 When the upper limit element 2701 of the upper limit lever 27 is screwed out, it can block the rotation of the mounting post 1701 by contacting its side. At this point, the position of the mounting post 1701 ensures that the signal element 18 inside the mounting post 1701 is coaxially aligned with the signal receiver 19. When the lower limit element 2801 of the lower limit lever 28 is screwed out, it can radially press against the side of the mounting plate 16 to fix the mounting plate 16 and prevent accidental rotation of the mounting plate 16 when the adjusting cup 20 is rotated. The structure of the lower limit lever 28 can be as follows: Figure 9 As shown, the lower limit element 2801 has an arcuate surface at its end to fit and contact the side of the mounting plate 16.
