Description

Technical Field

[0001] This invention relates to the field of water conservancy technology, and in particular to a vibration early warning device for water supply pipelines. Background Technology

[0002] Water supply pipelines often withstand significant pressure due to water supply requirements, and some pipelines experience large pressure fluctuations. Sudden changes in water volume frequently lead to water hammer, causing pipeline vibration. Pipeline connections, such as flanges, PE pipe sections, and sensor connection points (insertion flow meters), are most susceptible to vibration due to variations in pipeline structure and connection methods. Most pipeline leaks occur at these locations, making pipeline vibration one of the primary causes of leakage at these points.

[0003] Currently, when pipelines leak, management departments often fail to detect it in a timely manner, leading to significant water loss at the leak points, reduced water supply reliability, and even road collapses, traffic congestion, and large-scale water and power outages, as well as work stoppages and production shutdowns, causing considerable impact on society.

[0004] Therefore, we propose a water supply pipeline vibration early warning device to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a water supply pipeline vibration early warning device to solve the problems mentioned in the background art, such as the difficulty for management departments to detect pipeline leaks in a timely manner, resulting in a large amount of water loss at the leak point, reducing the water supply guarantee rate, and causing road collapses, traffic congestion, and even large-scale water and power outages, work stoppages and production shutdowns, which have a significant impact on society.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A water supply pipeline vibration early warning device includes an installation ring and a linkage structure. The installation ring has several centrally symmetrically distributed detection cylinders running through its interior. A telescopic rod is telescopically connected to one end of each detection cylinder facing the center of the installation ring, and a vibration detection ring is fixed to the other end of the telescopic rod facing the center of the installation ring. The vibration detection ring and the detection cylinders are connected by a spring sleeved on the outside of the telescopic rod. A vibration contact block for contacting the water supply pipeline is fixed to the other end of the vibration detection ring facing the center of the installation ring. Several vibration sensors are distributed in a ring shape inside the vibration detection ring to measure the vibration parameters of the water supply pipeline. A controller is installed on the outer wall of the installation ring, and the signal lines of the vibration sensors are electrically connected to the controller. The controller has a remote communication module for remote communication with a monitoring center.

[0008] The linkage structure includes a linkage gear ring coaxial with the mounting ring, linkage gears of the same number as the detection cylinders evenly distributed around the linkage gear ring, and a worm wheel threaded around the periphery of each detection cylinder. A worm is meshed around the periphery of the worm wheel, and the worm and the worm wheel are coaxially connected.

[0009] In a further embodiment, the controller is also equipped with a main control chip and a positioning module for monitoring the location of the central reverse positioning early warning device.

[0010] In a further embodiment, the inner ring of the mounting ring is provided with a plurality of stabilizers for stabilizing the rotation of the linkage gear ring. The stabilizer consists of a U-shaped limiting frame and balls rotatably mounted inside the limiting frame.

[0011] In a further embodiment, the front and rear outer walls of the linkage gear ring are provided with inwardly recessed arc-shaped grooves, and the part of the ball protruding from the limiting frame is in close contact with the groove.

[0012] In a further embodiment, a fixing frame is provided around the linkage gear, and an insert block is connected to the side of the fixing frame facing the detection cylinder, and a sliding groove is provided on the outer wall of the detection cylinder for the insert block to slide.

[0013] In a further embodiment, one of the worm gears is fitted with an adjusting handle at one end of the front end face of the mounting ring. The adjusting handle consists of a rod penetrating the worm gear shaft, a positioning ring fixed to the outer surface of the mounting ring, and a handle connected to the outer end of the rod. The end faces of the positioning ring and the handle that are close to each other are provided with annular teeth, and the positioning ring and the handle are connected by a spring.

[0014] In a further embodiment, a through wire groove is provided at the center of both the detection cylinder and the telescopic rod for laying wires.

[0015] In a further embodiment, the end of the detection cylinder facing the telescopic rod is provided with a square telescopic groove, and a plurality of rollers are rotatably installed on the outer wall of the end of the telescopic rod that extends into the telescopic groove, and the rollers are in close contact with the inner wall of the telescopic groove.

[0016] In a further embodiment, the mounting ring is composed of two symmetrical semi-rings, and the ends of the semi-rings protrude outwards and are connected to semi-threaded posts. The semi-threaded posts of the two semi-rings that are close to each other are threaded with nuts for locking the two semi-threaded posts.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. This invention involves installing a vibration early warning device on the periphery of a node section of a water supply pipeline. The vibration early warning device contacts the outer wall of the node section of the water supply pipeline via a vibration contact block. When the water supply pipeline vibrates, the vibration sensor detects the vibration parameters and transmits them remotely to the monitoring center of the management unit via a controller. The monitoring center effectively records the vibration frequency of the water supply pipeline. For abnormal vibration frequencies detected, the monitoring center can issue an early warning, thereby predicting the location of pipeline leaks. This allows the water supply management unit to promptly inspect and repair leaks, reducing water waste and preventing more dangerous accidents.

[0019] 2. The distance between the vibration contact blocks of the vibration early warning device in this invention can be adjusted, so as to make adaptive adjustments according to the thickness of different water supply pipe nodes in the early stage of installation. It is more practical and adaptable. Furthermore, the spacing of multiple vibration contact blocks can be adjusted synchronously through a linkage structure, which effectively simplifies the adjustment operation steps, makes the adjustment and use of the entire vibration early warning device more convenient, shortens the time required for early adjustment and assembly, and thus reduces the burden on installation workers.

[0029] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are used only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0030] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0031] 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figure 1-3 and Figure 8A vibration early warning device for water supply pipelines includes an installation ring 1 that is sleeved and installed around a node section of the water supply pipeline. After installation, the installation ring 1 coincides with the axis of the node section of the water supply pipeline. Several detection cylinders 3 are distributed around the circumference of the installation ring 1, and the detection cylinders 3 penetrate the installation ring 1 and are symmetrically distributed about the center of the installation ring 1. One end of the detection cylinder 3 facing the center of the installation ring 1 is connected to a telescopic rod 4 that can extend and retract relative to the detection cylinder 3. A vibration detection ring 5 is fixed to the end of the telescopic rod 4 facing the center of the installation ring 1. The vibration detection ring 5 and the detection cylinder 3 are connected by a spring 6 sleeved on the outside of the telescopic rod 4. A vibration contact for contacting the water supply pipeline is fixed to the end of the vibration detection ring 5 facing the center of the installation ring 1. Block 7, the vibration detection ring 5 has several vibration sensors 51 distributed in a ring shape inside. When the water supply pipeline vibrates, it squeezes the vibration contact block 7, which in turn squeezes the spring 6, causing the vibration sensor 51 to be subjected to force, thereby recording the vibration parameters of the water supply pipeline. In order to facilitate the management department to understand the vibration frequency at the detection point in a timely manner, a controller 2 is installed on the outer wall of the mounting ring 1, and the signal line of the vibration sensor 51 is electrically connected to the controller 2. At the same time, the controller 2 is equipped with a remote communication module for remote communication with the monitoring center, thereby transmitting the detected vibration parameters, so that the monitoring center can effectively record the vibration parameters. When an abnormal vibration frequency is detected, it can be recorded, thereby providing an early warning.

[0033] Please see Figure 2-3 Considering the varying thicknesses of water supply pipes during actual installation and use, the distance between contact blocks 7 needs to be adjusted accordingly. Therefore, the detection cylinder 3 can be adjusted in a movable and telescopic manner relative to the mounting ring 1. Furthermore, considering the complex operation and low efficiency of adjusting each detection cylinder 3 individually, a linkage structure is implemented. This linkage structure includes a linkage gear ring 8 coaxial with the mounting ring 1, a number of linkage gears 9 evenly distributed around the linkage gear ring 8 equal to the number of detection cylinders 3, and a worm wheel 11 threaded around the periphery of each detection cylinder 3. The worm wheel 11 is rotatably connected to the mounting ring 1, and a worm 10 meshes with the periphery of the worm wheel 11, with the worm 10 coaxially connected to the worm wheel 11. Therefore, when the linkage gear ring 8 rotates, it can synchronously drive several linkage gears 9 to rotate. The linkage gears 9 drive the worm 10 to rotate, and the worm 10 drives the worm wheel 11 to rotate. The worm wheel 11 and the detection cylinder 3 are engaged by a thread, causing the detection cylinder 3 to move closer to or further away from the center point of the mounting ring 1, thus achieving synchronous adjustment.

[0034] Please see Figure 8 To facilitate the management unit in quickly locating the leakage point during maintenance, controller 2 is also equipped with a main control chip and a positioning module. The positioning module can be used by the monitoring center to locate the location of the early warning device.

[0035] Please see Figure 6 To improve the stability of the linkage gear ring 8 during rotation, several stabilizers 13 are distributed on the inner ring of the mounting ring 1 to stabilize the rotation of the linkage gear ring 8. Each stabilizer 13 consists of a U-shaped limiting frame 131 and a ball bearing 132 rotatably mounted inside the limiting frame 131. The U-shaped limiting frame 131 supports the outer periphery of the linkage gear ring 8, while the ball bearing 132 is in close contact with the outer wall of the linkage gear ring 8, which can clamp the linkage gear ring 8 and improve its stability during rotation. At the same time, the outer walls on both the front and rear sides of the linkage gear ring 8 are provided with inwardly recessed arc-shaped grooves 81, and the part of the ball bearing 132 protruding from the limiting frame 131 is in close contact with the groove 81. Because the groove 81 is recessed, the ball bearing 132 can limit the rotation of the linkage gear ring 8 while assisting its rotation, preventing it from falling off.

[0036] Please see Figure 4-5 Considering that the detection cylinder 3 may rotate with the worm gear 11 when it rotates, thus failing to achieve the effect of movement, a fixed frame 91 is provided around the linkage gear 9. The fixed frame 91 is fixed to the mounting ring 1, and the linkage gear 9 is rotatably connected to the fixed frame 91. An insert block 92 is connected to the side of the fixed frame 91 facing the detection cylinder 3, and a sliding groove 32 is provided on the outer wall of the detection cylinder 3 for the insert block 92 to slide. Since the insert block 92 is inserted into the sliding groove 32, the detection cylinder 3 is limited to prevent the axial deflection of the detection cylinder 3. At the same time, when the detection cylinder 3 moves, the insert block 92 can slide along the sliding groove 32.

[0037] Please see Figure 4-5 To facilitate adjustment of the linkage structure, an adjustment handle 12 is provided. The adjustment handle 12 can be installed on the front face of the mounting ring 1, near any of the detection cylinders 3. One end of the worm gear 11, which passes through the front face of the mounting ring 1, is connected to the adjustment handle 12. The adjustment handle 12 consists of a rod 121 passing through the axis of the worm gear 11, a positioning ring 122 fixed to the outer surface of the mounting ring 1, and a handle 123 connected to the outer end of the rod 121. The handle 123 drives the rod 121 to rotate, and the rod 121 drives the worm gear 11 to rotate. This is to position the angle after rotation. The positioning ring 122 and the handle 123 are provided with annular teeth 124 on their adjacent end faces. The teeth 124 of the positioning ring 122 and the handle 123 mesh with each other, thereby locking the positioning ring 122 and the handle 123 in place and preventing them from rotating accidentally. At the same time, the positioning ring 122 and the handle 123 are connected by a second spring 125. The second spring 125 is in an extended state, thereby tightening the positioning ring 122 and the handle 123. When rotation is required, the handle 123 is pulled outward, causing the meshing teeth 124 to disengage, and the handle 123 can be rotated.

[0038] Please see Figure 3To facilitate the extension and retraction of the telescopic rod 4 during vibration testing, a square telescopic groove 31 is provided at one end of the detection cylinder 3 facing the telescopic rod 4. Several rollers 41 are rotatably installed on the outer wall of the end of the telescopic rod 4 that extends into the telescopic groove 31. The rollers 41 fit tightly against the inner wall of the telescopic groove 31, reducing the problem of shaking between the telescopic rod 4 and the square telescopic groove 31 due to gaps. At the same time, the rolling action of the rollers 41 can reduce sliding friction resistance, making the extension and retraction of the telescopic rod 4 smoother.

[0039] Please see Figure 3 To facilitate the laying of wires, a through wire groove 14 is provided at the center of both the detection cylinder 3 and the telescopic rod 4. The wire groove 14 of the telescopic rod 4 is connected to the telescopic groove 31 so that the wire connecting the vibration sensor 51 can pass out from the tail end of the detection cylinder 3 and connect to the controller 2.

[0040] Please see Figure 2 and Figure 7 To facilitate the installation and removal of the entire device without dismantling the water supply pipeline and to make it easier to install the warning device outside the existing pipeline, the installation ring 1 is composed of two symmetrical semi-rings 101, with the ends of the semi-rings 101 protruding outwards and connected to semi-threaded posts 102. The semi-threaded posts 102 of the two semi-rings 101 that are close to each other are threaded with nuts 103. After the nuts 103 are threadedly connected to the semi-threaded posts 102, the two semi-threaded posts 102 can be locked, thereby making the two symmetrical semi-rings 101 spliced ​​and locked together. Similarly, the linkage toothed ring 8 can also be divided into half and then spliced ​​and locked, which is convenient to operate.

[0041] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
