Description

Technical Field

[0001] This utility model relates to the field of hydropower facilities technology, and in particular to a water leakage monitoring and alarm device for hydropower station pipelines. Background Technology

[0002] The pipelines of hydropower stations are connected by straight connectors. The connection points of the pipelines are generally key areas for monitoring leaks. Under normal circumstances, workers are on-site to check for leaks, which consumes a lot of manpower and time, and it is impossible to detect leaks in a timely manner. In view of the above shortcomings, this patent proposes a pipeline leak monitoring device.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0028] Reference Figure 1 This is the first embodiment of the present invention. This embodiment provides a water leakage monitoring and alarm device for hydropower station pipelines, which can quickly detect pipeline leaks and issue an alarm. It includes a monitoring box 1, which has a water storage tank inside; a buoyancy control mechanism 2, which is installed inside the water storage tank. One end of the buoyancy control mechanism 2 is connected to an alarm 24, which is installed on the outer wall of the monitoring box 1.

[0029] Specifically, the buoyancy control mechanism 2 includes a float plate 21, which is attached to the surface inside the water storage tank. A connecting rod 23 is installed on the surface of the float plate 21, and a switch 22 is connected to one end of the connecting rod 23. The switch 22 is connected to the alarm 24.

[0030] The device is installed at the connection of the hydropower station pipeline. When the pipeline leaks, water enters the water storage tank of the monitoring box 1, causing the float plate 21 to float. After the float plate 21 floats, it drives the connecting rod 23 to rotate, thereby triggering the switch 22 and causing the alarm 24 to sound an alarm, thus reminding the staff that there is a leak at the pipeline connection and that it needs to be dealt with in time.

[0031] As an optional embodiment, refer to Figures 1-4 The monitoring box 1 has a first empty chamber 11 and a second empty chamber 12 on both sides near the water storage tank. The second empty chamber 12 has a horizontal partition 8 inside. The surface of the partition 8 has an installation port, and a solenoid valve is installed inside the installation port. A water pipe 9 is installed on the outer wall of the water storage tank near the bottom. The two ends of the water pipe 9 lead to the interior of the two second empty chambers 12.

[0032] Inside the second empty chamber 12, a red pill that is easily soluble in water and contains pigment is placed above the partition 8. Opening the solenoid valve will cause the red pill to fall to the bottom of the second empty chamber 12. After the water tank is filled with water, the water will be sent into the second empty chamber 12 through the water pipe 9. The red pill will turn the water red, making it easier for staff to see the abnormality and determine the location of the leak.

[0033] Furthermore, installation mechanisms 3 are provided on both sides of the top outer wall of the monitoring box 1, with one end of the installation mechanism 3 located inside the first empty chamber 11.

[0034] Furthermore, the installation mechanism 3 includes a vertical rod 31 and a first support frame 33. The first support frame 33 is installed on the surface of the first empty compartment 11. A strip groove is opened on the surface of the first empty compartment 11. The vertical rod 31 is slidably engaged with the inner wall of the strip groove. A pad 32 is slidably installed at the top of the vertical rod 31. The pad 32 is located inside the first support frame 33. Connecting rods 34 are movably installed at both ends of the pad 32. One end of each connecting rod 34 passes through the first support frame 33 on both sides. A clamping rod 36 is movably installed at one end of each connecting rod 34. A second support frame 35 is installed on the surface of the first support frame 33. The two clamping rods 36 are movably installed at both ends of the second support frame 35.

[0035] By moving the vertical rod 31, the clamping angle of the two clamping rods 36 can be changed through the two connecting rods 34, thereby clamping the pipe with the two clamping rods 36 and fixing the device below the pipe, which facilitates subsequent leakage monitoring.

[0036] Furthermore, a water immersion sensor 7 is installed on the inner wall of the water storage tank near the bottom.

[0037] After the water immersion sensor 7 detects water, it will send a signal to the alarm 24, which will then trigger the alarm and alert the staff that there is a water leak in the pipe.

[0038] Furthermore, a feed inlet 13 is opened on one side of the top outer wall of the second empty chamber 12, and multiple atomizing nozzles 42 are installed on the outer wall of the second empty chamber 12 near the bottom.

[0039] The water, stained red, is sprayed out from the atomizing nozzle 42, thus indicating a leak when red water mist is seen spraying out, serving as a warning.

[0040] Furthermore, a drive mechanism 4 is installed on the surface of the second empty chamber 12. The drive mechanism 4 includes a motor 41, which is installed on the surface of the second empty chamber 12. A rotating shaft 45 is installed at one end of the output shaft of the motor 41. Multiple stirring blades 43 are installed on the outer circumference of the rotating shaft 45. The stirring blades 43 are located below the partition plate 8. A first conical tooth 44 is sleeved on the outer circumference of the rotating shaft 45.

[0041] When in use, starting the motor 41 will drive the stirring blade 43 to rotate, thereby causing the red pill to dissolve quickly in the water and the water to quickly turn red.

[0042] As an optional embodiment, refer to Figures 1-5 A transmission mechanism 5 is installed on the inner wall of the second empty compartment 12 near the first empty compartment 11. The transmission mechanism 5 includes a movable shaft 51, which is rotatably inserted into the inner wall of the second empty compartment 12. A second bevel tooth 52 is sleeved on one end of the movable shaft 51, and the second bevel tooth 52 meshes with the first bevel tooth 44. A slot is opened at the end of the movable shaft 51 away from the second bevel tooth 52, and the slot is located inside the first empty compartment 11.

[0043] Furthermore, the first empty compartment 11 is provided with an adjustment mechanism 6, which includes a threaded rod 61. The threaded rod 61 is rotatably inserted into the first empty compartment 11. A miniature cylinder is provided inside the threaded rod 61. One end of the miniature cylinder is equipped with a plug 64, which is compatible with a slot. A rectangular plate 63 is installed on the outer wall of the threaded rod 61. The surface of the rectangular plate 63 has a slanted groove 62. The bottom end of the vertical rod 31 is engaged with a protrusion 37, which is slidably engaged inside the slanted groove 62.

[0044] In use, after placing the device below the pipe, first activate the miniature cylinder to insert the insert 64 into the slot. Then, start the motor 41, which drives the first bevel gear 44 to rotate. This rotation, via the second bevel gear 52 and the movable shaft 51, drives the threaded rod 61 to rotate, causing the rectangular plate 63 to rotate. This allows the protrusion 37 to slide within the inclined groove 62, thereby changing the height of the vertical rod 31 and thus the clamping angle of the clamping rod 36. This facilitates clamping pipes of different sizes. After clamping, disengage the miniature cylinder, disconnecting the transmission mechanism 5 and the adjustment mechanism 6. If the pipe leaks, water will enter. In the water storage tank, the water immersion sensor 7 directly triggers the alarm 24, and the floating plate 21 floats up. The connecting rod 23 flips the switch 22, which in turn triggers the alarm 24. At the same time, the switch 22 starts the motor 41 and the solenoid valve. The red pill falls from the partition 8, and the water in the water storage tank enters the interior of the second empty chamber 12 through the water pipe 9. The motor 41 drives the stirring blade 43 to rotate, accelerating the mixing of the water and the red pill inside the second empty chamber 12, turning the water red. Then, it is sprayed out by the atomizing nozzle, thus alerting the staff to the internal water leak.

[0045] In summary, a water leakage monitoring and alarm device for hydropower station pipelines is suitable for dimly lit environments and can quickly detect pipeline leaks and issue an alarm, thereby reminding staff to repair the leaking pipelines in a timely manner.
