Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1 Please see Figure 1-4 The present invention provides the following technical solution: an integrated inspection device for small and medium-sized hydropower stations, including an installation track 1, a control box 9 under the installation track 1, mounting plates 8 fixed on both sides of the upper end of the control box 9, a motor 7 mounted on one end of one mounting plate 8, a drive gear 12 connected to the output end of the motor 7, a rack 13 adapted to the drive gear 12 at the lower end of the installation track 1, fixing rods 6 fixed on both sides of the upper end of the control box 9, a slider 5 fixed on the other end of the fixing rods 6, grooves 4 corresponding to the slider 5 at both ends of the installation track 1, a connecting seat 11 under the control box 9, a monitoring equipment body 10 mounted on the lower end of the connecting seat 11, quick assembly and disassembly between the monitoring equipment body 10 and the connecting seat 11 through an installation component 3, and adjustment of the height and orientation of the monitoring equipment body 10 between the connecting seat 11 and the control box 9 through an adjustment component 2.

[0020] Specifically, the adjustment component 2 includes a motor 21. The motor 21 is installed on one side of the lower end of the control box 9. The output end of the motor 21 is connected to a lead screw 24. A sliding plate 25 is threadedly connected to the outside of the lead screw 24. A connecting post 26 is fixed at the middle of the lower end of the sliding plate 25. A connecting box 23 is fixed at the lower end of the connecting post 26. By adopting the above technical solution, starting the motor 21 drives the lead screw 24 to rotate, which can drive the sliding plate 25 to slide smoothly within the guide structure of the control box 9. The sliding action of the sliding plate 25 is synchronously transmitted to the connecting box 23 and the connecting seat 11 at the lower end through the connecting post 26, thereby driving the monitoring equipment body 10 to complete the lifting and lowering adjustment. This enables precise monitoring of different height areas of the hydropower station. Compared with the traditional structure, the adjustment component 2 greatly improves the lifting and lowering stability of the monitoring equipment body 10, effectively avoids equipment shaking, and ensures the clarity and integrity of the monitoring screen.

[0021] Specifically, the adjustment component 2 also includes a rotating shaft 27. The connecting seat 11 and the connecting box 23 are connected by the rotating shaft 27. A driven bevel gear 28 is fixed on the surface of the rotating shaft 27. A motor 22 is installed at one end of the connecting box 23 at a position corresponding to the driven bevel gear 28. The output end of the motor 22 is provided with a driving bevel gear 29. The driving bevel gear 29 meshes with the driven bevel gear 28 for transmission. By adopting the above technical solution, the motor 22 is started to drive the driving bevel gear 29 to rotate. With the meshing of the driving bevel gear 29 and the driven bevel gear 28, the rotating shaft 27 is driven to rotate stably in the connecting box 23. The rotation of the rotating shaft 27 will synchronously drive the connecting seat 11 at the lower end and the monitoring equipment body 10 to rotate horizontally, so as to realize the flexible adjustment of the viewing angle of the monitoring equipment body 10, break the limitation of the fixed monitoring viewing angle, significantly improve the inspection coverage of the equipment, and meet the all-round monitoring needs of the complex environment of the hydropower station.

[0022] Specifically, a threaded hole adapted to the lead screw 24 is provided on one side of the slide plate 25, and the side of the slide plate 25 is tightly fitted to the inner wall of the control box 9. By adopting the above technical solution, the slide plate 25 is provided with a threaded hole adapted to the lead screw 24 to ensure accurate transmission, and the side is tightly fitted to the inner wall of the control box 9 to limit the offset, making the lifting operation more stable and effectively avoiding equipment shaking.

[0023] Specifically, the lower end of the control box 9 is provided with a sliding hole that matches the connecting column 26, and the side of the connecting column 26 is tightly fitted with the inner wall of the sliding hole. By adopting the above technical solution, the lower end of the control box 9 is provided with a sliding hole that matches the connecting column 26, and the side walls of the two are tightly fitted, which not only provides precise guidance for the lifting and lowering of the connecting column 26, but also restricts its radial sway, further improving the stability and smoothness of the lifting and lowering of the monitoring equipment.

[0024] Specifically, a bearing rotating seat is installed at the connection between the rotating shaft 27 and the connecting box 23. The lower end of the rotating shaft 27 is fixedly connected to the connecting seat 11, and the upper end of the connecting seat 11 is in close contact with the lower end of the connecting box 23. By adopting the above technical solution, the rotating shaft 27 is equipped with a bearing rotating seat to achieve smooth rotation with low resistance. The connecting seat 11 is in close contact with the lower end of the connecting box 23 to limit radial offset and ensure that the monitoring equipment rotates smoothly and is positioned accurately.

[0025] In this embodiment, the starting motor 7 drives the gear 12 to rotate. The meshing transmission between the driving gear 12 and the rack 13 at the lower end of the mounting track 1 drives the control box 9 and the monitoring equipment body 10 on the lower side to move laterally along the track. The moving monitoring equipment body 10 performs comprehensive inspection and monitoring of the entire hydropower station environment. The starting motor 21 drives the lead screw 24 to rotate, which can drive the slide plate 25 to slide smoothly within the guide structure of the control box 9. The sliding action of the slide plate 25 is synchronously transmitted to the connecting box 23 and the connecting seat 11 at the lower end through the connecting column 26, thereby driving the monitoring equipment body 10 to complete the lifting and lowering adjustment. This enables precise monitoring of different height areas of the hydropower station. Compared with the traditional structure, this adjustment component 2 greatly improves the lifting and lowering stability of the monitoring equipment body 10, effectively avoids equipment shaking, and ensures the clarity and completeness of the monitoring screen.

[0026] The starter motor 22 drives the active bevel gear 29 to rotate. With the meshing of the active bevel gear 29 and the driven bevel gear 28, the rotating shaft 27 is driven to rotate stably in the connecting box 23. The rotation of the rotating shaft 27 will synchronously drive the lower connecting seat 11 and the monitoring equipment body 10 to rotate horizontally, so as to realize the flexible adjustment of the viewing angle of the monitoring equipment body 10, break the limitation of the fixed monitoring viewing angle, significantly improve the inspection coverage of the equipment, and meet the all-round monitoring needs of the complex environment of the hydropower station.

[0027] Example 2 The difference between this embodiment and embodiment 1 is that: the mounting component 3 includes a plug plate 32, the plug plates 32 are fixedly mounted on both sides of the upper end of the monitoring device body 10, the slots 33 adapted to the plug plates 32 are opened on both sides of the lower end of the connecting seat 11, and the sliding rods 31 are slidably connected to the connecting seat 11 at positions corresponding to the plug plates 32. A movable plate 34 is fixedly mounted on one side of the surface of the sliding rod 31, and a movable groove 35 adapted to the movable plate 34 is opened inside the connecting seat 11. A locking hole 37 corresponding to the sliding rod 31 is opened in the plug plate 32, and a spring 36 is sleeved on the outside of the sliding rod 31 between the movable plate 34 and the connecting seat 11. By adopting the above technical solution, the monitoring... The disassembly and maintenance of the device body 10 are achieved through the installation component 3. During installation, the slide bar 31 is pulled, which causes the moving plate 34 to slide in the moving groove 35 and compress the spring 36. Then, the plug plate 32 at the upper end of the monitoring device body 10 is precisely inserted into the slot 33 at the lower end of the connector 11. After the slide bar 31 is released, the spring 36 elastically returns to its original position and pushes one end of the slide bar 31 into the locking hole 37 of the plug plate 32, quickly completing the limiting of the plug plate 32 and achieving a firm fixation of the monitoring device body 10. This structure does not require additional tools and can complete the quick disassembly and assembly of the monitoring device body 10 independently, greatly improving the operational efficiency of daily inspection and maintenance.

[0028] Specifically, a pull ring 38 is fixedly provided at the end of the slide bar 31 away from the slot 33. An anti-slip pad is glued to the surface of the pull ring 38. By adopting the above technical solution, a pull ring 38 is fixedly provided at the end of the slide bar 31 away from the slot 33. An anti-slip pad is glued to the surface of the pull ring 38. This not only makes it convenient for the operator to manually pull the slide bar 31 to complete the disassembly and assembly, but also increases the friction of the hand, prevents slipping during operation, and improves the convenience and stability of the disassembly and assembly operation.

[0029] Specifically, the side of the slide rod 31 away from the pull ring 38 is designed with an arc shape, and the connecting seat 11 is provided with a sliding hole that matches the slide rod 31. By adopting the above technical solution, the end of the slide rod 31 is designed with an arc shape, which makes it easy to accurately and quickly snap into the insertion plate 32 locking hole 37. The connecting seat 11 is provided with a matching sliding hole to guide the slide rod 31 and limit its offset, making disassembly and assembly smoother and the positioning more stable.

[0030] Specifically, after the insert plate 32 is inserted into the slot 33, the side of the insert plate 32 fits tightly against the inner wall of the slot 33. The two insert plates 32 are symmetrically fixed on the upper end of the monitoring equipment body 10. By adopting the above technical solution, the insert plate 32 fits tightly against the inner wall of the slot 33. With the symmetrical arrangement of the two insert plates 32, the radial displacement of the monitoring equipment is effectively limited, the structural stability after installation is improved, and the monitoring screen does not shake.

[0031] In this embodiment, the disassembly and maintenance of the monitoring device body 10 are achieved through the installation component 3. During installation, the slide bar 31 is pulled, which causes the moving plate 34 to slide in the moving groove 35 and compress the spring 36. Then, the insert plate 32 at the upper end of the monitoring device body 10 is precisely inserted into the slot 33 at the lower end of the connector 11. After the slide bar 31 is released, the spring 36 elastically returns to its original position and pushes one end of the slide bar 31 into the locking hole 37 of the insert plate 32, quickly completing the limiting of the insert plate 32 and achieving a firm fixation of the monitoring device body 10. This structure does not require additional tools and can complete the quick disassembly and assembly of the monitoring device body 10 independently, greatly improving the operational efficiency of daily inspection and maintenance.

[0032] The working principle and usage process of this invention are as follows: First, install the device in a suitable position, start motor 3 7 to drive gear 12 to rotate, and use the meshing transmission between drive gear 12 and rack 13 at the lower end of mounting track 1 to drive control box 9 and the monitoring equipment body 10 on the lower side to move laterally along the track. The moving monitoring equipment body 10 can perform comprehensive inspection and monitoring of the entire hydropower station environment. Start motor 1 21 to drive lead screw 24 to rotate, which can drive slide plate 25 to slide smoothly in the guide structure of control box 9. The sliding action of slide plate 25 is synchronously transmitted to the lower connecting box 23 and connecting seat 11 through connecting column 26, thereby driving the monitoring equipment body 10 to complete the lifting and lowering adjustment, thereby realizing accurate monitoring of different height areas of the hydropower station. Compared with the traditional structure, this adjustment component 2 greatly improves the lifting and lowering stability of monitoring equipment body 10, effectively avoids equipment shaking, and ensures the clarity and completeness of the monitoring screen.

[0033] The starter motor 22 drives the active bevel gear 29 to rotate. With the meshing of the active bevel gear 29 and the driven bevel gear 28, the rotating shaft 27 is driven to rotate stably in the connecting box 23. The rotation of the rotating shaft 27 will synchronously drive the lower connecting seat 11 and the monitoring equipment body 10 to rotate horizontally, so as to realize the flexible adjustment of the viewing angle of the monitoring equipment body 10, break the limitation of the fixed monitoring viewing angle, significantly improve the inspection coverage of the equipment, and meet the all-round monitoring needs of the complex environment of the hydropower station.

[0034] The disassembly and maintenance of the monitoring equipment body 10 are achieved through the installation component 3. During installation, the slide bar 31 is pulled, which causes the moving plate 34 to slide in the moving groove 35 and compress the spring 36. Then, the insertion plate 32 at the upper end of the monitoring equipment body 10 is precisely inserted into the slot 33 at the lower end of the connector 11. After the slide bar 31 is released, the spring 36 elastically returns to its original position and pushes one end of the slide bar 31 into the locking hole 37 of the insertion plate 32, quickly completing the limiting of the insertion plate 32 and achieving a firm fixation of the monitoring equipment body 10. This structure does not require additional tools and can complete the quick disassembly and assembly of the monitoring equipment body 10 independently, greatly improving the operational efficiency of daily inspection and maintenance.
