Description

Technical Field

[0001] This invention belongs to the field of wind power monitoring and protection technology, specifically referring to a protection device for monitoring points. Background Technology

[0002] Wind power generation refers to converting the kinetic energy of wind into electrical energy. Wind energy is a clean and pollution-free renewable energy source. A windmill is a type of power machine that does not require fuel and uses wind as its energy source. Wind power measurement work involves monitoring wind direction, wind speed, and wind stability, which is accomplished by anemometer towers. This involves selecting installation locations for windmills and collecting the kinetic energy of the wind. Wind power generation areas include land, wetlands, and oceans. Wind measurement towers are mainly constructed by assembling steel frames to fix the measuring instruments at high altitudes. As the foundation for wind measurement, the wind measurement towers are not retractable, making them very cumbersome to erect and move. Moreover, wind measurement towers may be used on uneven ground, requiring verticality measurements during installation. Furthermore, because wind measurement towers are located at high altitudes, they are popular landing and nesting sites for birds, making existing towers difficult to adjust. Cleaning their upper walls can easily reduce the accuracy of wind measurement data. Summary of the Invention

The counter-control top contact component provides support for the inclined surface in a close-fitting connection through the reaction output, ensuring its fixation and stability. At the same time, the nested extension adjustment component uses the nesting principle to achieve fixation and extension of different lengths. The self-weight swing vertical device uses gravity as the driving adjustment force to realize the self-vertical placement of the monitoring device.

[0004] The technical solution adopted by this invention is as follows: This invention provides a protection device for a monitoring point, including a nested retraction control assembly, a self-weight swinging vertical device, a protective shell, and a reverse control top contact assembly.

The first fixing coil and the second fixing coil are arranged opposite to each other. When the first fixing coil and the second fixing coil are energized, they generate a magnetic field that attracts each other. Through the action of the magnetic field, the outer fixing component and the sliding component are fixed together.

[0007] In a preferred embodiment of the present invention, the self-weight swing-type vertical device includes a first rotating shaft, a first rotating component, a second rotating shaft, and a self-weight swing-type vertical component. The first rotating shaft is movably mounted on the inner wall of the protective shell. The first rotating component is connected to the first rotating shaft. The second rotating shaft is movably connected to the first rotating component. The self-weight swing-type vertical component is connected to the second rotating shaft. The nested retraction adjustment assembly is fixedly mounted on the self-weight swing-type vertical component. When the device needs to be transported and used, when the operator moves the device on an inclined surface, the self-weight swing-type vertical component and the first rotating component adjust and rotate relative to each other according to the terrain. The first rotating component and the protective shell adjust and rotate relative to each other according to the terrain. The self-weight swing-type vertical component is in a vertically downward state due to its own weight.

[0011] Furthermore, the control rod contains a hydraulic rod, the movable end of which is connected to the embedded control rod one. When the device to be monitored is installed on the monitoring mounting plate, the coil is de-energized, and then the hydraulic rod operates to push the embedded control rod one upwards.

Coil 27 and coil 28 are positioned opposite each other, coil 39 and coil 4 are positioned opposite each other, and coil 5 and coil 6 are positioned opposite each other. Hydraulic rod 33 is provided inside control rod 23, and the movable end of hydraulic rod 33 is connected to embedded control rod 20.The device to be monitored is installed on the monitoring mounting plate 19. The coil is de-energized, and then the hydraulic rod 33 operates to push the embedded control rod 1 20 upwards. The embedded control rod 1 20 drives the embedded clip 1 24 upwards. When the embedded clip 1 24 moves to the end of the embedded control rod 21, it pushes the embedded control rod 21, causing the embedded control rod 21 to drive the embedded clip 25 upwards. When the embedded clip 25 moves to the end of the embedded control rod 3 22... The embedded control lever 22 is pushed, causing the embedded clip 26 to move upwards. When the clip 26 reaches the end of the control lever 23, it stops moving.

[0027] In practical use: Initially, the fixed adsorption coil 35 and the fixed adsorption coil 13 are energized, generating a magnetic field that attracts each other. Under the influence of this attraction, the sliding member 10 is positioned close to the bottom wall of the protective shell 3. The coils within the nested retraction control assembly 1 are energized, and coils 27 and 28 attract each other, coils 29 and 30 attract each other, and coils 31 and 32 attract each other, thus fixing the nested retraction control assembly 1 for easy transport. When the device needs to be transported, as the operator moves the device on an inclined surface, the self-weight swinging vertical member 18 and the rotating member 16 adjust according to the terrain and rotate relative to each other. The rotating member 16 and the protective shell... 3. Adjust the rotation according to the terrain. The self-weight swinging vertical member 18 is in a vertical downward state due to its own weight. Even on sloping ground, the self-weight swinging vertical member 18 is still set in a vertical state, which is convenient for subsequent installation. After reaching the destination, the self-weight swinging vertical member 18 is set in a vertical state, the power is cut off in the first fixed coil 11 and the second fixed coil 14, and the sliding member 10 moves upward along the outer fixed member 6 under the push of the second spring 12. The sliding member 10 pushes the top contact fitting member 7 upward. The top contact fitting member 7 is set against the bottom wall of the self-weight swinging vertical member 18. With the push of the second spring 12 and the reaction of the self-weight swinging vertical member 18, the top contact fitting member 7 retracts into the sliding member 10, the first spring 8 is compressed, and the first spring 8 presses against the fixed plate 9. As the pressure increases, the pressure sensor on the fixed plate 9 senses the pressure and transmits the information to the controller. The controller then energizes the corresponding fixed coil 11 and fixed coil 24, causing the sliding member 10 to adhere to the outer fixed member 6, thus supporting the self-weight swinging vertical member 18. The device to be monitored is then installed on the monitoring mounting plate 19. The coil inside the nested retraction control assembly 1 stops energizing, and the hydraulic rod 33 works to push the embedded control rod 20 upwards. The embedded control rod 20 drives the embedded clip 24 upwards. When the embedded clip 24 reaches the end of the embedded control rod 21, it pushes the embedded control rod 21, causing the embedded control rod 21 to drive the embedded clip 25 upwards. When the embedded control rod 22 is moved to its end, it is pushed, causing the embedded clip 26 to move upward. When the embedded clip 26 moves to the end of the control rod 23, it stops moving. Then, the coil in the nested retraction control assembly 1 is energized again, and coil 27 and coil 28 attract each other, coil 39 and coil 4 and coil 30 attract each other, and coil 5 and coil 6 and coil 32 attract each other, thus fixing the embedded control rod 20, embedded control rod 21, and embedded control rod 22 in sequence. When cleaning or monitoring is completed and movement is required, the coil in the nested retraction control assembly 1 is de-energized, and the hydraulic rod 33 works to drive the monitoring mounting plate 19 and the nested retraction control assembly 1 to retract in sequence.
