Description

Technical Field

[0001] This utility model belongs to the technical field of hydropower plant systems. Specifically, it relates to a DLC data acquisition device for a hydropower plant automation system. Background Technology

[0002] Integrated hydropower data acquisition converts various operating data obtained from sensors, such as water level, flow rate, pressure, and temperature, into digital signals and stores them internally. Simultaneously, these signals are displayed in real-time on a touchscreen, allowing engineers to monitor data changes. Dynamic laser ranging (DLC) technology works by emitting a laser beam towards a target object and then calculating the distance between the target object and the laser by receiving the reflected laser signal. This method allows for the determination of the target object's position in three-dimensional space.

[0003] However, existing DLC ​​data acquisition devices are inconvenient to monitor water temperature and acquire data during use, resulting in insufficient data acquisition. Utility Model Content

[0024] Example:

[0025] like Figure 1 and Figure 3 As shown, the DLC data acquisition device for the hydropower plant automation system of this utility model includes a mounting plate 1 and a temperature measuring component 6. A mounting groove 2 is provided on the surface of one end of the mounting plate 1, and a DLC sensor 3 is installed on the mounting groove 2. A first electric push rod 4 is installed at the lower end of the mounting plate 1, and a limit rod 12 is installed on the output section of the first electric push rod 4. The limit rod 12 is used for the installation of the temperature measuring component 6 and also for the limiting installation of the foam board 501. The first electric push rod 4 controls the position of the limit rod 12 and the temperature measuring component 6 by extension and retraction, so that the temperature measuring sensor 7 can detect the water temperature of the reservoir in the hydropower plant from more positions.

[0026] In some embodiments, the limiting rod 12 is provided with an auxiliary component 5 for assisting in visually viewing the water level, and the limiting rod 12 is in the shape of a hollow circular tube.

[0027] Specifically, auxiliary component 5 includes a foam board 501 and a reflective strip 502. The reflective strip 502 is located on the outer edge of the surface of the foam board 501. The foam board 501 floats on the reservoir surface due to its own buoyancy, making it easy for data monitoring personnel to intuitively determine the water surface position. A mounting hole is provided at the center of the foam board 501, and a limiting rod 12 passes through the mounting hole on the foam board 501, limiting the foam board 501 to the limiting rod 12. The foam board 501 is slidably connected on the limiting rod 12, and when subjected to buoyancy, the foam board 501 can slide onto the water surface.

[0028] The auxiliary component 5 also includes an auxiliary rod 503 and a fixing plate 504. The auxiliary rod 503 is arranged parallel to the limiting rod 12. An auxiliary hole is provided on the foam board 501. The auxiliary rod 503 passes through the auxiliary hole on the foam board 501. The foam board 501 is slidably connected to the auxiliary rod 503. The top of the auxiliary rod 503 is provided with a fixing plate 504. The fixing plate 504 is fixedly connected to the limiting rod 12. The auxiliary rod 503 and the limiting rod 12 prevent the foam board 501 from rotating as the water level rises and falls. The reflective strip 502 facilitates the view of personnel.

[0029] A lower support plate 8 is provided on the exterior of the end of the mounting plate 1 away from the DLC sensor 3. The lower support plate 8 provides support when the mounting plate 1 moves. A second electric push rod 9 is provided on the lower support plate 8. The output end of the second electric push rod 9 is connected to the mounting plate 1. The mounting plate 1 is moved by extension and retraction, which facilitates the adjustment of the horizontal position of the DLC sensor 3. A column 10 is installed at the lower end of the lower support plate 8, and a ground fixing plate 11 is installed at the lower end of the column 10, which can be fixed to the ground.

[0030] like Figure 2 As shown, a temperature measuring component 6 for acquiring water temperature data is provided at the end of the limiting rod 12.

[0031] The specific temperature measuring component 6 includes a mounting box 601, a threaded layer 602, a temperature measuring hole 603, and a base plate 604. The threaded layer 602 is integrally formed with the mounting box 601 and fixed to the inner wall of the mounting box 601. The interior of the mounting box 601 is used to place the temperature sensor 7, preventing damage to the temperature sensor 7 caused by water flow fluctuations, which would affect the acquisition of monitoring data. The side wall of the mounting box 601 has a temperature measuring hole 603. The base plate 604 is connected to the interior of the mounting box 601 by a threaded connection, and the upper end of the base plate 604 is provided with the temperature sensor 7. The threaded layer 602 allows the base plate 604 to be moved to a suitable position in the mounting box 601 according to the size of the temperature sensor 7. This prevents the temperature sensor 7 from shaking in the mounting box 601 while installing temperature sensors 7 of different sizes. Four temperature measuring holes 603 are evenly distributed in a ring on the side wall of the mounting box 601. The temperature measuring holes 603 allow the temperature sensor 7 to directly contact the water for measurement, ensuring the accuracy of the data.

[0032] When using the aforementioned DLC data acquisition device for the hydropower plant automation system, first install the column 10 and the ground fixing plate 11 on the bank of the hydropower plant reservoir. Then, install the DLC sensor 3 on the mounting plate 1. The DLC sensor 3 (model IMPULSE 100) uses dynamic laser ranging (DLC) technology, which uses a laser to emit a laser beam towards the target object and then calculates the distance between the target object and the laser by receiving the reflected laser signal, thereby acquiring water level data in a timely manner. Next, place the temperature sensor 7 in the mounting box 601 and install the base plate 604. During the installation of the temperature sensor 7, the threaded layer 602 allows the base plate 604 to be installed according to the temperature sensor 7 (E52-IC). The dimensions of the AY) are moved to a suitable position in the mounting box 601. While installing temperature sensors 7 of different sizes, it also prevents the temperature sensors 7 from shaking in the mounting box 601. The temperature measuring hole 603 allows the temperature sensors 7 to directly contact the water for measurement, ensuring the accuracy of the data. During monitoring, the first electric push rod 4 extends to control the position of the limit rod 12 and the temperature measuring component 6, allowing the temperature sensors 7 to detect the water temperature in the reservoir of the hydropower plant from more positions. Underwater, the mounting box 601 can prevent the temperature sensors 7 from being damaged by water flow fluctuations, which would affect the acquisition of monitoring data. During daily monitoring, the second electric push rod 9 can be controlled to extend and retract to control the distance between the mounting plate 1 and the column 10, which facilitates the adjustment of the sensor position. Personnel can also visually determine the water surface position through the foam board 501 outside the limit rod 12.
