[0034] [First Embodiment]

[0035] like Figure 1-8 The image shows a pipeline flow direction detection device provided in the first embodiment of this utility model, such as... Figure 1-2 As shown, the device includes a fixing part 1 fixed to the top of the pipe network. The fixing part 1 provides top support and connection position for the bracket 2. The top of the bracket 2 is hinged to the fixing part 1, so that the bottom of the bracket 2 can rotate around the hinge position with the fixing part 1. This allows it to rotate with the water flow when a large amount of water is discharged from the pipe network, thereby reducing the impact damage to the detection device. The bottom of the bracket 2 is respectively provided with a float assembly 3 and a lever assembly 4. The float assembly 3 is heavier than the lever assembly 4 and is located on top of the lever assembly 4, so that the bottom lever assembly 4 can be automatically reset by the float assembly 3. The float assembly 3 is fixedly connected to the bracket 2. Furthermore, it can move synchronously with the water flow, thereby causing the bracket 2 to rotate relative to the fixed part 1. The paddle assembly 4 is rotatably connected to the bracket 2 and has a trigger ball 5 and a trigger switch 6 inside. The trigger ball 5 can move relative to the trigger switch 6, and the paddle assembly 4 can move synchronously with the water flow, thereby causing the trigger ball 5 to move relative to the trigger switch 6. The installation requires low precision, reducing manufacturing and maintenance costs while facilitating installation and removal. At the same time, the float assembly can drive the bracket to rotate, thereby driving the bracket to rotate when there is water flow impact and driving the bracket to reset when there is no water flow impact, thus effectively achieving the automatic reset effect.

[0036] like Figure 1-2 As shown, in this embodiment, a signal receiving module 8 is fixed on the top of the fixing part 1. The signal receiving module 8 is connected to the trigger switch 6. The trigger switch 6 can send signals through the signal receiving module 8 to the line to realize timed monitoring of the water flow status and direction. Preferably, the signal receiving module 8 and the trigger switch 6 are connected by a wire 7. The wire 7 is set inside the bracket 2, thereby further protecting the wire 7 to improve the safety of the detection device and extend its service life.

[0037] like Figure 1-2As shown, correspondingly, the bracket 2 in this embodiment is set as a hollow bracket. The top of the bracket 2 is provided with a bracket hinge hole 21 that rotatably cooperates with the fixing part 1. The bottom of the bracket 2 is respectively fixed with a float fixing shaft 22 that is fixedly cooperated with the float assembly 3 and a paddle fixing shaft 23 that rotatably cooperates with the paddle assembly 4. While realizing the rotation of the bottom of the bracket around the top hinge position, it is also conducive to realizing the synchronous movement of the float assembly 3 driving the bracket 2 and the rotation of the paddle assembly 4 relative to the bracket 2.

[0038] like Figure 2 As shown, the float assembly 3 in this embodiment includes a float body 31, and a float hinge hole 32 is provided inside the float body 31. The float fixing shaft 22 passes through the float hinge hole 32. When a large amount of water flows out of the pipe network, the float assembly 3 can drive the support to rotate, thereby driving the support to rotate when there is water flow impact, reducing water flow impact and extending service life. When there is no water flow impact, the support is driven to reset, thereby effectively achieving the automatic reset effect.

[0039] like Figure 2 As shown, the paddle assembly 4 in this embodiment includes a float 41, and a paddle 42 is fixedly connected to the bottom of the float 41. By setting the paddle, the contact area with the water flow can be effectively increased, thereby improving the detection accuracy and stability.

[0040] like Figure 3 As shown, a float hinge hole 411 is provided inside the float 41, and the paddle fixing shaft 23 passes through the float hinge hole 411. At the same time, a receiving groove 412 is also provided inside the float 41, and the trigger switch 6 is installed inside the receiving groove 412. The receiving groove 412 is located at the top of the float hinge hole 411, and the receiving groove 412 gradually extends downward from the middle to both sides, so that the trigger switch 6 inside it also gradually extends downward from the middle to both sides. In addition, the float 41 has a movement channel 413 inside. The trigger ball 5 is rolled inside the movement channel 413. The movement channel 413 is located at the bottom of the float hinge hole 411 and extends upward from the middle to both sides. This makes the middle position of the movement channel 413 the farthest from the trigger switch 6, while the two sides of the movement channel 413 are closest to the trigger switch 6. Thus, the closest distance between the two sides of the movement channel 413 and the trigger switch 6 can be set as the trigger preset value. When there is no water flow, the trigger ball 5 is located in the middle position of the movement channel 413, which is the farthest from the trigger switch 6. The trigger preset value has not been reached, so the trigger switch 6 is closed. When there is water flow, the trigger ball 5 is located on both sides of the movement channel 413, which is the closest to the trigger switch 6. The trigger preset value has been reached, so the trigger switch 6 is opened.

[0041] In one preferred embodiment, the trigger ball 5 can be a magnetic ball, and the trigger switch 6 can be a magnetic switch, satisfying the following:

[0042] When the distance between the trigger ball 5 and the trigger switch 6 is less than or equal to a preset value on one side, the trigger switch 6 turns on and sends a positive signal to the signal receiving module 8.

[0043] When the distance between the trigger ball 5 and the trigger switch 6 is less than or equal to a preset value on the other side, the trigger switch 6 turns on and sends a negative signal to the signal receiving module 8.

[0044] When the distance between the trigger ball 5 and the trigger switch 6 is greater than a preset value, the trigger switch 6 is turned off.

[0045] This allows the system to detect whether water is flowing inside the pipe network, and also to determine the direction of water flow based on the sign of the signal.

[0046] The specific working process of this embodiment is as follows:

[0047] When the pipeline is dry, the trigger ball 5 is in the middle of the internal movement path 413 of the float ball 41, at which point it is furthest from the trigger switch 6. Since the preset trigger value has not been reached, the trigger switch 6 is closed and no signal is generated. Figure 4-5 As shown.

[0048] When the pipe network is experiencing a small water outflow, the water flow pushes the lever 42, causing the float 41 to rotate counterclockwise around the hinge axis. This causes the trigger ball 5 to move to the left within the internal movement channel 413 of the float 41. At this time, the contact distance between the trigger ball 5 and the trigger switch 6 reaches the preset trigger value. The trigger switch 6 then opens and sends a positive signal to the signal receiving module 8 for online monitoring. Figure 6-7 As shown.

[0049] When the pipeline is experiencing a large outflow of water, to prevent the water level from completely submerging the lever assembly 4, the float assembly 3 will drive the bracket 2 to rotate counterclockwise at high water levels. The water flow will push the lever 42, causing the float 41 to rotate counterclockwise around the hinge axis. This will cause the trigger ball 5 to move to the left within the movement track 413 of the float 41. At this time, the contact distance between the trigger ball 5 and the trigger switch 6 reaches the preset trigger value. The trigger switch 6 will then open and send a positive signal to the signal receiving module 8 for online monitoring. Figure 8 As shown.

[0050] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
