[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 intelligent inspection and online monitoring device for hydropower stations, including a base assembly 1, a support rod 8 above the base assembly 1, a top plate cylinder assembly 5 fixedly installed on the outer side of the top of the support rod 8, a movable ring assembly 7 fixedly connected below the top plate cylinder assembly 5 and located outside the support rod 8, a probe assembly 4 fixedly installed on one side of the movable ring assembly 7, an equipment box assembly 6 fixedly connected on the side of the movable ring assembly 7 away from the probe assembly 4, the base assembly 1 and the support rod 8 are connected by an tilting adjustment device 2, and a drying and demisting device 3 is fixedly connected below the movable ring assembly 7 and located outside the probe assembly 4. The tilting adjustment device 2 includes a support column 21. The support column 21 is fixedly installed on the side of the base assembly 1 near the support rod 8. A connecting frame 28 is provided between the support column 21 and the support rod 8. A rotating shaft 27 is installed on the inner side of the connecting frame 28 through a bearing. An inclined plate 24 is fixedly installed on the side of the support rod 8 near the connecting frame 28. The rotating shaft 27 and the inclined plate 24 are connected by a rotating block 26. The support column 21 and the connecting frame 28 are connected by an adjustment assembly 22.

[0020] Specifically, abutment blocks 23 are provided on both sides of the rotating block 26, and the two abutment blocks 23 are connected to the connecting frame 28 through two electric telescopic rods 25.

[0021] By adopting the above technical solution, the staff can use the cooperation of two abutment blocks 23 and two electric telescopic rods 25 to hold the inclined plate 24 in place when needed, thereby preventing it from rotating and preventing accidental rotation.

[0022] Specifically, the positioning component 22 includes a fixed box 222. The fixed box 222 is fixedly installed on the side of the support column 21 near the connecting frame 28. A motor 224 is fixedly installed on one side of the fixed box 222. A lead screw 223 is fixedly connected to the side of the motor 224 near the fixed box 222. A moving block 221 is fixedly installed below the connecting frame 28 and at a position outside the lead screw 223 and inside the fixed box 222.

[0023] By adopting the above technical solution, staff can adjust the left and right positions of the probe assembly 4 with the help of the lead screw 223 and other structures when needed, so as to better meet the monitoring needs in different situations.

[0024] Specifically, the inner side of the fixed box 222 and the outer side of the movable block 221 are fitted together.

[0025] By adopting the above technical solution, the device can limit the movement of the moving block 221 by a certain extent through the fixed box 222, thereby preventing accidental movement and better meeting the needs of the work.

[0026] In this embodiment, when the intelligent inspection of a hydropower station requires the use of an online monitoring device, the base assembly 1 is a structure fixed at the work site. Then, the two electric telescopic rods 25 in the tilt adjustment device 2 are activated, thereby driving the two abutment blocks 23 to rise and fall respectively, which in turn pushes the tilt plate 24 and the rotating block 26 and rotating shaft 27 in the lower connecting frame 28 to rotate, thereby adjusting the tilt of the probe assembly 4 and other structures. Then, the motor 224 in the adjustment assembly 22 is activated, thereby driving the lead screw 223 to rotate. The lead screw 223 is threadedly connected to the moving block 221, and the outer side of the moving block 221 is in contact with the inner side of the fixed box 222. Therefore, the lead screw 223 drives the moving block 221 and other structures to move, thereby adjusting the left and right position of the probe assembly 4. Then, the height of the movable ring assembly 7 is adjusted by the top plate cylinder assembly 5 on the support rod 8, thereby adjusting the height of the probe assembly 4 and the equipment box assembly 6. Then, the detection work can be carried out by the probe assembly 4. The support column 21 plays a supporting role.

[0027] Example 2 The difference between this embodiment and embodiment 1 is that the drying and demisting device 3 includes a connecting frame 31. The connecting frame 31 is fixedly connected to the lower part of the movable ring assembly 7 and located outside the probe assembly 4. A connecting box 38 is fixedly installed on the bottom inner side of the connecting frame 31. A fan 36 is fixedly installed below the connecting box 38. Silica gel desiccant 37 is provided on the inner side of the connecting box 38. A nozzle 32 is fixedly installed on the upper part of the connecting box 38 and located above the probe assembly 4.

[0028] By adopting the above technical solution, staff can remove and dry the water mist on the probe assembly 4 when needed by using the combination of the fan 36 and silica gel desiccant 37, thereby reducing the impact of water mist on the probe assembly 4.

[0029] Specifically, a fixing mesh 35 is fixedly installed on the inner side of the connecting box 38 and on both the upper and lower sides of the silica gel desiccant 37.

[0030] By adopting the above technical solution, the device can prevent silica gel desiccant 37 from entering the fan 36 and nozzle 32 through two fixed nets 35, thereby reducing the possibility of adverse effects on the operation and ensuring the normal operation of the work.

[0031] Specifically, a plug block 33 is threadedly installed on the side of the connecting box 38 away from the support rod 8 and below the connecting frame 31.

[0032] By adopting the above technical solution, staff can unscrew the block 33 to replace the silica gel desiccant 37 when needed, thereby reducing the difficulty of replacing the silica gel desiccant 37 and alleviating the workload of staff.

[0033] Specifically, a transparent window 34 is fixedly installed on the inner side of the blocking block 33.

[0034] By adopting the above technical solution, staff can observe the state of silica gel desiccant 37 through the transparent window 34 when needed, which facilitates timely replacement and better meets the needs of the work.

[0035] In this embodiment, when water mist appears in the surrounding environment, the operator can start the fan 36 in the drying and demisting device 3 to send air into the connecting box 38. The silica gel desiccant 37 between the two fixed nets 35 dries the air. Then, the dried air is sprayed from the nozzle 32 onto the probe assembly 4, thereby removing and drying the water mist on the probe assembly 4, reducing the impact of water mist on the probe assembly 4, and better meeting the needs of the work. The connecting bracket 31 serves as a connection. When needed, the operator can unscrew the blocking block 33 to replace the silica gel desiccant 37, and can also observe the status of the silica gel desiccant 37 through the transparent window 34.

[0036] The structure and principle of the base assembly 1 (comprising a lower base, an upper base, a first threaded hole, a slot, and a second threaded hole), the probe assembly 4 (comprising a support plate, a servo motor, a rotating shaft, and a monitoring probe), the top plate cylinder assembly 5 (comprising a top plate, a solar panel, a cylinder, and a movable rod), the equipment box assembly 6 (comprising an equipment box and an antenna), the movable ring assembly 7 (comprising a movable ring and a fixed seat), and the support rod 8 have been disclosed in a hydropower station online monitoring device disclosed in Chinese patent application number 202222232988.7. Its working principle is that during the installation process, the operator inserts the upper base into the slot inside the lower base, inserts bolts into the first and second threaded holes, and tightens the bolts until the upper base and lower base are completely secured. The device can be installed, and the wireless transmission module can transmit data to the cloud via an antenna for online monitoring. Simultaneously, the output shaft of the servo motor can drive the monitoring probe to rotate, allowing for angle changes. The top plate can shield against rain, preventing water from entering the monitoring probe or the equipment box. The movable end of the cylinder transmits power to the fixed base via a movable rod. The fixed base can then move the monitoring probe up and down via a movable ring, allowing for probe height adjustment and facilitating equipment box maintenance. The solar panel converts solar energy into electricity, which is transmitted via wiring to a battery inside the equipment box for storage. This stored electricity powers the monitoring equipment, improving the device's energy efficiency. The overall design is reasonable and easy to use.

[0037] The working principle and usage process of this invention are as follows: When the intelligent inspection of a hydropower station requires the use of an online monitoring device, the base assembly 1 is a structure fixed at the work site. Then, the two electric telescopic rods 25 in the tilt adjustment device 2 are activated, thereby driving the two abutment blocks 23 to rise and fall respectively, which in turn pushes the tilt plate 24 and the rotating block 26 and rotating shaft 27 in the lower connecting frame 28 to rotate, thereby adjusting the tilt of the probe assembly 4 and other structures. Then, the motor 224 in the adjustment assembly 22 is activated, thereby driving the lead screw 223 to rotate. The lead screw 223 is threadedly connected to the moving block 221, and the outer side of the moving block 221 is in contact with the inner side of the fixed box 222. Therefore, the lead screw 223 drives the moving block 221 and other structures to move, thereby adjusting the left and right position of the probe assembly 4. Then, the top plate cylinder assembly on the support rod 8 is activated. The height of the movable ring assembly 7 is adjusted by component 5, thereby adjusting the height of the probe assembly 4 and the equipment box assembly 6. Detection can then be performed through the probe assembly 4. The support column 21 provides support. When water mist appears in the surrounding area, the operator can start the fan 36 in the drying and demisting device 3 to send air into the connecting box 38. The silica gel desiccant 37 between the two fixed nets 35 dries the air. The dried air is then sprayed from the nozzle 32 onto the probe assembly 4, thereby removing and drying the water mist on the probe assembly 4, reducing the impact of water mist on the probe assembly 4, and better meeting the needs of the operation. The connecting bracket 31 serves as a connector. When needed, the operator can unscrew the blocking block 33 to replace the silica gel desiccant 37, or observe the status of the silica gel desiccant 37 through the transparent window 34.

[0038] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
