Description

Technical Field

[0001] This utility model relates to the field of hydropower station water level information acquisition technology, specifically a remote information acquisition device for hydropower station operation. Background Technology

[0002] A hydropower station consists of a hydraulic system, a mechanical system, and an electrical power generation device. It is a water conservancy project that realizes the conversion of water energy into electrical energy. The sustainability of electrical power production requires that the utilization of water energy in hydropower stations be uninterrupted. Through the construction of the reservoir system of a hydropower station, the distribution of water resources in time and space can be artificially regulated and changed to achieve the sustainable utilization of water resources. As for the changes in water level within the hydropower station, water level acquisition devices are needed to collect water level change information in real time.

[0003] The published patent document CN222825111U discloses a hydropower station water level data acquisition device. In this patent, a buoyant ball moves with the rise and fall of the water level, causing a measuring rod to move inside a protective casing. A laser rangefinder detects the distance to a sliding platform, thus obtaining water level data. During use, the measuring rod's surface may be covered with debris and dust, affecting its sliding within the protective casing. A water pump is activated to draw water in through the inlet, which is then sent through a connecting pipe to a connecting ring and sprayed out through a nozzle to clean the measuring rod's surface, preventing interference with its sliding and ensuring the accuracy of the water level data acquisition. However, in the aforementioned patent document, the vertical movement of the measuring rod and sliding platform during water level detection involves sliding friction. The buoyant ball is subjected to both vertical buoyancy and horizontal impact forces from the water flow. The horizontal impact force results in significant sliding friction on the measuring rod and sliding platform, sometimes preventing them from moving and leading to poor accuracy in water level data acquisition.

Detailed Implementation

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] Please see Figure 1-3 and Figure 5 This utility model provides a remote information acquisition device for hydropower station operation, including a crossbar 1 and a cylindrical shell 4. A groove 2 is provided on one side of the crossbar 1, and a matching crossbar 3 is slidably connected inside the groove 2. The end of the crossbar 3 outside the groove 2 is fixedly installed to the cylindrical shell 4. A moving plate 13 and a measuring plate 14 are provided inside the cylindrical shell 4, and a circular hole 11 is provided at the bottom of the cylindrical shell 4. Several laser rangefinders 24 are fixedly installed on the outer edge of the bottom of the measuring plate 14, and several... A ball bearing 12 is fixedly installed at the bottom of the moving plate 13. The lower end of the measuring shaft 5 passes through the round hole 11 and is fixedly installed with a float ball 6. The measuring shaft 5 is in contact with the ball bearing 12. Several U-shaped parts 15 are fixedly installed at equal intervals on the outer wall of the moving plate 13. A ball bearing 16 is rotatably installed inside the U-shaped parts 15. Several limiting rods 17 are fixedly connected at equal intervals on the inner wall of the cylinder shell 4. The limiting rods 17 are provided with ball grooves 18 that match the ball bearing 16. Part of the ball bearing 16 is located inside the ball groove 18.

[0025] In this technical solution, when collecting water level information at a hydropower station, the float 6 drives the measuring shaft 5 to move vertically according to the water level. The measuring shaft 5 drives the moving disk 13 to move inside the shell 4. The laser rangefinder 24 detects the change in distance from the moving disk 13 to measure the change in water level. Furthermore, the first ball 12 in the circular hole 11 forms rolling friction with the measuring shaft 5, and the ball groove 18 on the limiting rod 17 forms rolling friction with the second ball 16. This prevents the horizontal force generated by the water flow from causing excessive sliding friction, which would prevent the measuring shaft 5 and the moving disk 13 from moving vertically, thus ensuring the accuracy of water level information collection.

[0026] In some technical solutions, such as Figure 1 and Figure 4 As shown, a servo motor 7 is fixedly installed on the top of the crossbar 1. The output end of the servo motor 7 passes through the top of the crossbar 1 and is fixedly installed with a bevel gear 21. A lead screw 20 is rotatably installed inside the slide groove 2. A threaded groove 23 matching the lead screw 20 is opened on one side of the crossbar 3 inside the slide groove 2. A bevel gear 22 is sleeved on the lead screw 20 and fixedly installed. One end of the lead screw 20 is inside the threaded groove 23. The thread helix angle of the lead screw 20 is less than the equivalent friction angle. The bevel gear 21 and the bevel gear 22 are meshed and connected.

[0027] In use, the servo motor 7 drives the bevel gear 21 to rotate, and the bevel gear 21 and the bevel gear 22 drive the lead screw 20 to rotate. The lead screw 20 drives the crossbar 3 to move along the slide groove 2 through the threaded groove 23, thereby adjusting the position of the shell 4 laterally so as to collect water level information at various positions of the water flow on the same vertical section.

[0028] In some technical solutions, such as Figure 1 , Figure 3 and Figure 6 As shown, a matching cylinder cover 8 is provided on the top of the cylinder shell 4, and an external threaded ring 19 is sleeved and fixedly connected to the upper side of the cylinder shell 4. An internal threaded ring 27 that matches the external threaded ring 19 is fixedly connected to the bottom of the cylinder cover 8. The internal threaded ring 27 and the external threaded ring 19 are threadedly connected.

[0029] In use, the inner threaded ring 27 can be unscrewed from the outer threaded ring 19 by rotating the cylinder cover 8, which facilitates the installation and disassembly of the cylinder cover 8 and the cylinder shell 4, thereby facilitating the internal maintenance of the cylinder shell 4.

[0030] In some technical solutions, such as Figure 6 As shown, a sealing ring 28 matching the cylinder shell 4 is fixedly connected to the bottom inner wall of the cylinder cover 8.

[0031] During use, the sealing ring 28 increases the sealing performance of the cylinder cover 8 and the cylinder shell 4.

[0032] In some technical solutions, such as Figure 1 and Figure 5 As shown, a wireless transceiver controller 25 with an external power supply is fixedly installed in the middle of the bottom of the measuring disk 14. The laser rangefinder 24 and the servo motor 7 are all electrically connected to the wireless transceiver controller 25.

[0033] When in use, information can be remotely controlled and collected via the wireless transceiver controller 25.

[0034] In some technical solutions, such as Figure 3 and Figure 5 As shown, several connecting rods 26 are fixedly connected to the outer wall of the measuring disc 14, and the connecting rods 26 are fixedly installed to the inner wall of the cylindrical shell 4.

[0035] In use, the connecting rod 26 provides a mounting point for the measuring disc 14.

[0036] In some technical solutions, such as Figure 1 As shown, a mounting plate 9 is welded to one end of the crossbar 1, and a number of mounting holes 10 are provided on the mounting plate 9.

[0037] When in use, the device can be easily installed at the water level detection point of the hydropower station through the mounting holes 10 on the mounting plate 9.

[0038] Working principle: During use, the float 6 drives the measuring shaft 5 to move vertically according to the water level. The measuring shaft 5 drives the moving disk 13 to move inside the cylinder shell 4. The laser rangefinder 24 detects the change in distance from the moving disk 13 to measure the change in water level. Rolling friction is formed between the first ball 12 in the round hole 11 and the measuring shaft 5, and rolling friction is formed between the ball groove 18 on the limit rod 17 and the second ball 16. This prevents the horizontal force generated by the water flow from causing excessive sliding friction, which would prevent the measuring shaft 5 and the moving disk 13 from moving vertically. The servo motor 7 can drive the first bevel gear 21 to rotate. The first bevel gear 21 and the second bevel gear 22 drive the lead screw 20 to rotate. The lead screw 20 drives the second crossbar 3 to move along the slide groove 2 through the threaded groove 23, thereby adjusting the position of the cylinder shell 4 laterally to adjust the position of the water level detection.

[0039] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
