Description

Technical Field

[0001] This utility model relates to the field of fault detection technology, specifically to a fault detection device for pipeline systems. Background Technology

[0002] A check valve is a valve used in piping systems. During operation, pressure causes the valve to open when the medium flows in the forward direction, thus opening the passage. When the medium flows in the reverse direction, the valve closes, preventing backflow. This structure is commonly used in circulating water systems to ensure normal system operation and reduce the risk of backflow damaging the system.

[0003] In industrial systems, this valve is widely used to ensure the normal operation of the medium. However, this valve is prone to damage during daily use. If the valve malfunctions during operation, the medium delivery may fail to meet requirements, potentially affecting system operation. Furthermore, due to the special installation location of check valves, it is difficult for personnel to detect faults and determine the direction of medium flow. In circulating systems, check valve damage can cause system pressure drops, and if not addressed promptly, it can lead to system shutdown and significant economic losses. Utility Model Content

[0004] To address the shortcomings of existing technologies, a pipeline system fault detection device is proposed, which solves the problem in the background technology that, due to the special installation location of check valves, it is inconvenient for personnel to detect faults and difficult to detect the direction of medium flow.

[0005] To achieve the above objectives, the present invention proposes the following technologies:

[0006] A pipeline system fault detection device includes an actuating mechanism and an alarm mechanism. The actuating mechanism is located inside the pipeline and moves with the change of the medium flow direction. When the medium flows in the reverse direction, the actuating mechanism triggers the alarm mechanism and generates an alarm signal to remind the staff.

[0007] Furthermore, the actuation mechanism includes a movable plate, which impacts the surface of the movable plate and drives the movable plate to move in order to trigger the warning mechanism when the medium flows.

[0008] Furthermore, the movable plate is rotatably connected to the pipe via a fixed shaft, which is arranged perpendicular to the flow direction of the medium so that the medium can drive the movable plate to rotate along the fixed shaft.

[0009] Furthermore, support frames for installing warning mechanisms are respectively provided on both sides of the fixed shaft, and baffles are fixed on the support frames to limit the movable plate and thus trigger the warning mechanism.

[0010] Furthermore, the warning mechanism includes stationary contacts and moving contacts spaced apart within the support frame. The movable plate approaches the support frame and drives the moving contacts to contact the stationary contacts to trigger an alarm.

[0011] Furthermore, the stationary contact is fixedly installed inside the support frame, and the moving contact is located on the side of the stationary contact closer to the movable plate. Magnets of the same polarity are respectively provided on the surface of the moving contact and the end of the movable plate.

[0012] Furthermore, the warning mechanism also includes a wire and a signal light connected to the wire. The stationary contact and the moving contact are located at the two ends of the wire, respectively. When the stationary contact and the moving contact are in contact, the signal light emits a signal.

[0013] Furthermore, the stationary contact includes a first stationary contact, and the moving contact includes a first moving contact. When the first moving contact comes into contact with the first stationary contact, the indicator light emits an alarm signal.

[0014] Furthermore, the stationary contact also includes a second stationary contact, and the moving contact also includes a second moving contact. When the second moving contact contacts the second stationary contact, the indicator light emits a normal operation signal.

[0015] Furthermore, the first and second moving contacts are located in the support frames on both sides, respectively, so as to cooperate with the movable plate to emit signals corresponding to the flow direction of the medium.

[0016] Compared with the prior art, the comprehensive effects brought about by this utility model include:

[0017] By setting up an actuating mechanism, when the flow direction of the medium changes in the pipeline, the actuating mechanism can be driven to move and trigger the warning mechanism. The warning mechanism generates an alarm signal to promptly notify the staff of the backflow of the medium in the pipeline, thereby realizing the fault detection function, facilitating timely detection of valve devices, and preventing losses caused by backflow of the medium.

[0021] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] In this document, terms such as “up,” “down,” “left,” “right,” and “top” indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] like Figures 1 to 2 As shown, a pipeline system fault detection device includes an actuating mechanism and an alarm mechanism. The actuating mechanism is located inside the pipeline and moves with the change of the medium flow direction. When the medium flows in the reverse direction, the actuating mechanism triggers the alarm mechanism and generates an alarm signal to remind the staff.

[0024] By setting up an actuating mechanism, when the flow direction of the medium changes in the pipeline, it can drive the actuating mechanism to move and trigger the warning mechanism. The warning mechanism generates an alarm signal to promptly notify the staff of the backflow of the medium in the pipeline, thereby realizing the fault detection function. This device can be used in conjunction with a check valve, installed before and after the check valve, to detect the flow direction of the medium, thereby determining whether the check valve is faulty and providing early warning. This prevents the check valve from being damaged without timely detection and handling, facilitates timely inspection of valve devices, and prevents losses caused by backflow of the medium.

[0025] In the pipeline system fault detection device of this embodiment, the actuating mechanism includes a movable plate 1. When the medium flows, it impacts the surface of the movable plate 1 and drives the movable plate 1 to move to trigger the warning mechanism.

[0026] The actuation mechanism is set as a movable plate 1, which facilitates the contact between the medium and the plate plane, thereby driving the movable plate 1 to move through the flow of the medium. Thus, when the flow direction of the medium changes, the actuation mechanism can act in a timely manner and trigger the warning mechanism.

[0027] In the pipeline system fault detection device of this embodiment, the movable plate 1 is rotatably connected to the pipeline through the fixed shaft 2. The fixed shaft 2 is arranged perpendicular to the flow direction of the medium so that the medium can drive the movable plate 1 to rotate along the fixed shaft 2.

[0028] The movable plate 1 is rotatably installed inside the pipeline. By further improving the responsiveness of the movable plate 1 to changes in the direction of medium flow, the structure allows the side with a larger surface area of ​​the movable plate 1 to directly meet the impact of the medium flow, increasing the force on the movable plate 1 and ensuring that the movable plate 1 can rotate smoothly around the fixed axis 2 and trigger the warning mechanism.

[0029] In the pipeline system fault detection device of this embodiment, support frames 3 for installing warning mechanisms are respectively provided on both sides of the fixed shaft 2. A baffle 4 is fixed on the support frame 3 to limit the movable plate 1 and thus trigger the warning mechanism.

[0030] The support frame 3 is set to facilitate the installation of the warning mechanism. The baffle 4 limits the rotation angle of the movable plate 1 to prevent the movable plate 1 from being driven to rotate continuously by the medium flow. At the same time, the baffle 4 limits the movable plate 1 to maintain a certain angle, thereby ensuring that the warning mechanism can be effectively triggered.

[0031] In the pipeline system fault detection device of this embodiment, the warning mechanism includes a stationary contact and a moving contact spaced apart in the support frame 3. The movable plate 1 approaches the support frame 3 and drives the moving contact to contact the stationary contact to trigger the alarm of the warning mechanism.

[0032] With the above settings, when the medium in the pipeline flows backward, the movable plate 1 rotates and is limited by the baffle 4. At the same time, it causes the moving contact to move and contact the stationary contact, triggering the warning mechanism. This makes it easy for staff to detect the backflow in time and realize the alarm detection function.

[0033] In the pipeline system fault detection device of this embodiment, the stationary contact is fixedly installed in the support frame 3, the moving contact is located on the side of the stationary contact close to the movable plate 1, and the surface of the moving contact and the end of the movable plate 1 are respectively provided with magnets 5 of the same pole.

[0034] Specifically, the magnet 5 is fixed on the back of the moving contact. When the end of the movable plate 1 with the same pole magnet 5 is blocked by the baffle 4, the moving contact is pushed by the magnet 5 to approach and fit the stationary contact due to the repulsion of like poles, thereby triggering the warning mechanism.

[0035] Based on the above structure, the contacts are made conductive due to magnetic force. With the help of the contact settings, they can be connected to alarm lights or online detection systems, enabling various forms of detection alarms and making them suitable for various media flow detection scenarios.

[0036] Preferably, the warning mechanism further includes a wire and a signal light connected to the wire. The stationary contact and the moving contact are located at the two ends of the wire, and the wire is connected to a power source. When the stationary contact and the moving contact make contact with the conductive circuit under the action of magnetic force, the signal light emits a signal to remind the staff that there is a backflow of medium in the pipeline.

[0037] In the pipeline system fault detection device of this embodiment, the stationary contact includes a first stationary contact 6, and the moving contact includes a first moving contact 7. When the first moving contact 7 contacts the first stationary contact 6, the indicator light emits an alarm signal. The stationary contact also includes a second stationary contact 8, and the moving contact also includes a second moving contact 9. When the second moving contact 9 contacts the second stationary contact 8, the indicator light emits a normal operation signal.

[0038] Specifically, corresponding to the two support frames 3 set on both sides, contact components are respectively set in the support frames 3. The first moving contact 7 and the second moving contact 9 are located in the support frames 3 on both sides respectively. With the different rotation directions of the movable plate 1, the different contacts on both sides engage to send a signal corresponding to the flow direction of the medium.

[0039] In this embodiment, when the medium flows to the right, it causes the movable plate 1 to rotate counterclockwise. The first moving contact 7 and the first stationary contact 6 in the left support frame 3 come into contact, and point AB is connected, causing the indicator light on the AB circuit to emit a signal. When the medium flows to the left, point AC is connected, and the second moving contact 9 and the second stationary contact 8 in the right support frame 3 come into contact, connecting point AC, and causing the indicator light on this circuit to emit a signal. The specific left and right directions and the meaning of the indicator lights can be determined according to the normal and reverse flow directions of the medium under actual use.

[0040] Preferably, the first moving contact 7 and the second moving contact 9 can be connected to the same point A, and different indicator lights can be controlled according to the connectivity between A and B or C, thereby reducing the use of wiring and connectors.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0042] Although embodiments of the present invention have been shown and described in detail, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
