Description

Technical Field

[0001] This utility model belongs to the field of pipeline pressure detection technology. Specifically, it relates to an automatic pipeline pressure alarm device. Background Technology

[0002] Pipeline pressure refers to the pressure exerted by the fluid inside the pipeline on the pipe wall. The magnitude of this pressure depends on factors such as the fluid density, flow velocity, and the shape, size, and material of the pipeline. In a pipeline system, pipeline pressure is an important parameter that relates to the safe operation of the pipeline, the efficiency of fluid transport, and the selection of equipment. In order to maintain the normal operation of the pipeline system, it is usually necessary to monitor and control the pipeline pressure.

[0003] Currently, hydraulic devices are widely used in turbine governors to open and close guide vanes, with hydraulic oil delivered through pressure pipelines. The governor system requires the pipeline pressure to be maintained within a certain range. If the pipeline pressure is too low, the guide vanes' response to control signals will be slower, or they may even fail to open or close. Excessive pipeline pressure can easily lead to safety risks. Existing pressure sensors can only detect pressure at a fixed location, resulting in insufficient accuracy. Furthermore, they cannot provide alerts when the detected pressure is too low or too high, leading to slow guide vane response or even failure to open or close. Utility Model Content

[0004] The purpose of this invention is to provide an automatic pipeline pressure alarm device to address the aforementioned shortcomings. This solves the problems of existing pressure sensors, which can only detect pressure at a fixed location, lack sufficient accuracy, and fail to provide alerts when the detected pressure is too low or too high. To achieve the above objective, this invention provides the following technical solution:

[0005] An automatic pipeline pressure alarm device includes a connection box; both sides of the connection box are provided with insert rings, which seal and connect two sets of pipelines to form a connection; a square hole is opened at the top of the connection box; a wire box is provided inside the square hole; an arc-shaped hole runs vertically through the wire box; a matching arc-shaped wire conduit is sealed and connected inside the arc-shaped hole and extends into the connection box; a rigid wire is provided inside the arc-shaped wire conduit; the lower end of the rigid wire extends out of the arc-shaped wire conduit and is connected to a pressure sensor for detecting the pressure state of the fluid in the pipeline; the bottom of the rigid wire is slidably sealed to the bottom opening of the arc-shaped wire conduit; a wire control box is provided above the wire box for controlling the extension and retraction of the wire and fixing the wire; a control alarm module is provided on the wire control box; the control alarm module is electrically connected to the pressure sensor.

[0006] Furthermore, a limiting ring is fixedly connected to the inner wall of the bottom end of the arc-shaped conduit; the outer wall of the rigid wire is slidably sealed to the inner wall of the limiting ring.

[0007] Furthermore, the bottom two outer walls of the wire control box are provided with round holes; a collar is fixedly connected to the inner wall of the round hole; a shaft core is rotatably connected to the center of the collar; a turntable is fixedly connected to the outer end of the shaft core; a threaded rod is fixedly connected to the inner end of the shaft core; a threaded sleeve is threadedly connected to the threaded rod; a clamp is fixedly connected to the end of the threaded sleeve away from the threaded rod; two clamps are slidably disposed inside the wire control box; the rigid wire is located between the two clamps.

[0008] Furthermore, a rubber pad is provided on the side of the clip facing the rigid wire.

[0009] Furthermore, the wire control box is equipped with a forward and reverse motor, whose output shaft is sequentially fixedly connected to a gear and a transmission wheel; a shaft is rotatably connected inside the wire control box; the shaft is arranged parallel to the output shaft, and a gear and a transmission wheel are sequentially arranged in the extension direction; the diameter of the gear is smaller than that of the transmission wheel; the two transmission wheels mesh; the rigid wire is located between the two gears.

[0010] Furthermore, the two gears rotate in opposite directions to push or retract the rigid wire.

[0011] Furthermore, the control alarm module includes an analysis controller and an alarm; the analysis controller is used to determine whether the pressure value detected by the pressure sensor is too high or too low and to control the alarm to sound an alarm.

[0012] Furthermore, the lower end of the analysis controller is provided with a spring wire; the bottom of the spring wire is electrically connected to the top of the rigid wire.

[0013] Furthermore, the rigid conductor has a certain degree of toughness, allowing it to be bent but not easily bent or rolled up.

[0014] Furthermore, the alarm includes a sound module and an LED module.

[0015] The beneficial effects of this utility model are:

[0016] 1. When the operator rotates both sets of turntables simultaneously, the threaded rods on the two sets of shafts will rotate together. At this time, the two sets of threaded sleeves will move back and forth on the outer wall of the threaded rods, and the clamps will slide back and forth against the top surface of the wire box. When the two sets of clamps slide in opposite directions at the same time, they can clamp and fix the rigid wire, thereby preventing the rigid wire from being dragged by the fluid. When the forward and reverse motor drives one set of transmission wheels to rotate, the other set of gears will also rotate together. At this time, the two gears rotate in opposite directions, which can push or retract the rigid wire. When pushing the rigid wire, the pressure sensor can be inserted into the designated position, which helps to improve the accuracy of pressure detection.

[0017] 2. By setting up a pressure sensor, the pressure in the pipeline can be detected. By setting up an analysis controller, the pipeline pressure detection results can be analyzed. By setting up an alarm, when the pipeline pressure detection result is too high or too low compared with the normal pressure range, the alarm will immediately sound and flash to remind the staff to take appropriate measures.

[0025] Example:

[0026] See attached Figures 1-4This embodiment provides an automatic pipeline pressure alarm device, including a pipe junction box 1: it can be made of cast iron (or PVC, depending on the corrosiveness of the transported medium), and has an overall rectangular hollow structure. Its internal cavity communicates with the pipes on both sides, forming a fluid flow channel. Circular insert rings 2 are integrally formed on the left and right end faces of the pipe junction box 1. The pipes on both sides are connected to the insert rings 2 through a sealing connection, thus connecting the two pipes. The insert rings 2 can be set with an outer diameter slightly smaller than the inner diameter of the pipes to be connected. The outer wall of the insert rings 2 has two annular grooves, in which oil-resistant rubber sealing rings are embedded. During installation, the two sets of pipes are respectively fitted onto the insert rings 2 on both sides and fixed by flanges or hose clamps. The sealing rings are compressed to achieve a sealed connection between the pipes and the pipe junction box 1, preventing fluid leakage. A square hole is opened at the top of the pipe junction box 1, and a wire box 3 is sealed and connected inside the square hole. The wire box 3 can be made of ABS engineering plastic, has a square box structure, and its size is adapted to the square hole at the top of the pipe junction box 1. It is connected to the square hole by bolts or other fixing methods, and a sealing gasket is provided at the contact point between the box and the square hole. A through-hole arc-shaped opening is provided on the wire box 3, and an arc-shaped wire tube 4 is fitted inside the opening. This arc-shaped tube can be made of metal (such as brass) or high-strength nylon, and its curvature matches the arc-shaped opening on the wire box 3. The arc-shaped wire tube 4 is fixed in the arc-shaped opening by threaded connection or glue sealing, with its lower end extending into the inside of the connector box 1 and its upper end flush with the upper surface of the wire box 3, forming a sealed channel through the wire box 3. A rigid wire 11 is installed inside the arc-shaped wire tube 4. This rigid wire has a certain degree of flexibility, allowing it to be bent but not easily coiled, and its smooth surface facilitates sliding. A limiting ring 10 with an inner diameter matching the diameter of the rigid wire 11 is welded to the inner wall of the bottom end of the arc-shaped wire tube 4 to further achieve sliding sealing. This can be achieved using existing technology, such as embedding a U-shaped fluororubber sealing ring near the opening at the bottom end of the limiting ring 10. The inner diameter of the sealing ring is interference-fitted with the diameter of the rigid wire 11, and the outer ring is fixed to the inner groove of the arc-shaped wire conduit 4 with adhesive. The fluororubber material is resistant to high and low temperatures (-20℃ to 200℃) and chemical corrosion, making it suitable for various fluid media. When the rigid wire 11 moves, its outer wall remains in contact with the inner wall of the limiting ring 10, restricting the radial movement of the wire and ensuring uniform contact pressure between the wire and the sealing ring. Simultaneously, the fluororubber sealing ring undergoes elastic deformation due to the interference fit, tightly wrapping around the surface of the wire to form a sealing barrier, blocking the path of fluid penetration through gaps. One end of the rigid wire 11 extends into the pipe and is connected to a pressure sensor 9. The sensor probe faces the direction of fluid flow in the pipe, allowing real-time detection of fluid pressure and conversion of the pressure signal into an electrical signal transmitted through the wire.

[0027] In this embodiment, round holes are provided at the bottom of the outer walls on both sides of the wire control box 5, and a collar 12 is fixedly connected to the inner wall of each round hole. A shaft core 13 is rotatably connected to the inner wall of each collar 12. A turntable 14 is fixedly connected to one end of each set of shaft cores 13 facing the outside of the wire control box 5. The turntables 14 are located on both sides of the outside of the wire control box 5. A threaded rod 15 is fixedly connected to the inside of each set of shaft cores 13 facing the inside of the wire control box 5. A threaded sleeve 16 is threadedly connected to the outer wall of each threaded rod 15. Each threaded sleeve 16 has a clamping plate 17 fixedly connected to its opposite face. When the operator rotates both sets of turntables 14 simultaneously, the threaded rods 15 on the two sets of shafts 13 will rotate together. At this time, the two sets of threaded sleeves 16 will move back and forth on the outer wall of the threaded rods 15, causing the clamping plates 17 to slide back and forth against the top surface of the wire box 3. When the two sets of clamping plates 17 slide in opposite directions at the same time, the rigid wire 11 can be clamped and fixed, thereby preventing the rigid wire 11 from being dragged by the fluid. Furthermore, a rubber pad is provided on the end face of the clamping plate 17 facing the rigid wire 11 to reduce the pressure on the rigid wire 11.

[0028] In this embodiment, the wire control box 5 is equipped with a forward and reverse motor 18. The output shaft of the forward and reverse motor 18 extends into the body of the wire control box 5. A circular hole is opened at the rear end of the wire control box 5, and a shaft 19 is rotatably connected to the inner wall of the circular hole. The output end of the forward and reverse motor 18 and the shaft 19 are arranged in parallel. Gears 20 and transmission wheels are fixedly connected in sequence at the output end and the front end of the shaft 19. The teeth and grooves of the two transmission wheels mesh with each other. The gear 20 is located at the front end of the transmission wheel. The outer wall of the transmission wheel is in close contact with the outer wall of the rigid wire 11. When the forward and reverse motor 18 drives one transmission wheel to rotate, the other transmission wheel will also rotate together, thereby driving the two gears 20 to rotate in opposite directions, which can push or retract the rigid wire 11. When pushing the rigid wire 11, the pressure sensor 9 can be inserted into the designated position, which helps to improve the accuracy of pressure detection.

[0029] In this embodiment, the control alarm module includes an analysis controller 6 and an alarm 7. The analysis controller 6 uses a microcontroller as its core and is installed on the wire control box 5. It is connected to the pressure sensor 9 via a spring wire 8 and a rigid wire 11 to ensure continuous circuit connection. The controller has preset upper and lower pressure thresholds (which can be modified via an external button or a host computer). The alarm 7 is integrated on the surface of the wire control box 5 and includes a sound module: a high-decibel buzzer that emits a continuous alarm sound when the pressure is too high or too low; and an LED module: a red warning light that flashes when an alarm is triggered, while a green running light remains constantly lit to indicate normal operation. The pressure sensor 9 transmits pressure signals to the analysis controller 6 in real time. The controller compares the detected value with the threshold. When the value exceeds the threshold range, the alarm 7 is immediately triggered; the alarm automatically stops when the pressure returns to normal.

Any equivalent structural or procedural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
