[0063] Power plant, also known as power station, is a kind of infrastructure which converts primary energy in nature into electric energy. The conversion of energy in power plant needs a lot of electrical automation equipment, such as generators, transformers and the like, to cooperate and complete. These electrical automation equipment are often expensive and complex in structure, and once damaged, they need a long maintenance period. Therefore, it is necessary to monitor these electrical automation equipment in real time during daily operation to prevent accidents from happening or expanding.

[0064] The existing power plant monitoring device includes a monitor and a fixed support, wherein the fixed support is placed on the ground, and the fixed support is provided with a mounting platform capable of driving the monitor to rise and fall. In use, the worker drives the mounting platform to drive the monitor to rise or fall to different levels to monitor the electrical automation equipment at different heights.

[0065] However, in the long-term use process, the lens surface of the monitor is easy to be contaminated with dust, and directly using a cleaning brush to clean the lens will cause the lens to be scratched, thereby affecting the clarity of the monitoring picture.

[0066] Based on this, the monitoring device provided by the embodiments of the present application includes a support platform, a driving assembly, a moving assembly and a protection assembly, wherein the driving assembly includes a driving rod and a driving piece, and the protection assembly includes a protection cover.

[0067] When the staff needs to monitor the electrical automation equipment located at different heights, the driving member operates to drive the driving rod to rotate around its own axis, thereby driving the moving assembly connected with the driving rod to ascend and descend, and since the monitor is installed on the moving assembly, the ascending and descending of the moving assembly can drive the monitor to ascend and descend together, so as to adjust the monitoring height of the monitor.

[0068] During the operation of the monitoring device, the protective cover can cover the monitor, effectively isolating the monitor from the external environment, and preventing dust in the external environment from covering the lens surface of the monitor. After the operation of the monitoring device is completed, the staff only needs to clean the dust on the surface of the protective cover, without the need to clean the lens surface of the monitor.

[0069] Therefore, the embodiments of the present application adjust the monitoring height of the monitor through the cooperation between the driving assembly and the moving assembly. Meanwhile, the protective cover avoids unnecessary damage to the lens of the monitor during daily cleaning, ensures the clarity of the monitoring picture, and prolongs the service life of the monitor.

[0070] The technical solutions of the embodiments of the present application will be described in detail below with reference to the specific embodiments combined with the drawings. The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described in detail in some embodiments.

[0071] Referring to Figure 1 and Figure 2 It is shown that the embodiments of the present application provide a monitoring device, which comprises a support platform 100, a support cylinder 110 arranged on the support platform 100; a driving assembly 200, the driving assembly 200 comprising a driving rod 210 and a driving member 220, the driving rod 210 being installed in the support cylinder 110, and the driving end of the driving member 220 being connected with one end of the driving rod 210 to drive the driving rod 210 to rotate around its own axis; a moving assembly 300, the moving assembly 300 being connected with the driving rod 210, the driving rod 210 driving the moving assembly 300 to ascend and descend, and the moving assembly 300 being installed with a monitor 400; a protective assembly 500, the protective assembly 500 comprising a protective cover 510, the protective cover 510 covering the monitor 400, and the protective cover 510 being detachably connected with the moving assembly 300 to cover or expose the monitor 400.

[0072] In the embodiment of the present application, when the staff needs to monitor the electrical automation equipment at different heights, the driving member 220 operates to drive the driving rod 210 to rotate around the axis of the driving rod 210, thereby driving the moving assembly 300 connected with the driving rod 210 to ascend and descend, and since the monitor 400 is installed on the moving assembly 300, the ascending and descending of the moving assembly 300 can drive the monitor 400 to ascend and descend together, so as to adjust the monitoring height of the monitor 400.

[0073] During the operation of the monitoring device, the protective cover 510 can cover the monitor 400, effectively isolating the monitor 400 from the external environment, preventing dust in the external environment from covering the lens surface of the monitor 400, and causing the clarity of the monitoring picture to decrease. After the operation of the monitoring device is completed, the staff only needs to clean the dust on the surface of the protective cover 510.

[0074] Therefore, the embodiment of the present application adjusts the monitoring height of the monitor 400 through the cooperation between the driving assembly 200 and the moving assembly 300. Meanwhile, the protective cover 510 can avoid unnecessary damage to the lens of the monitor 400 during daily cleaning, ensures the clarity of the monitoring picture, and prolongs the service life of the monitor 400.

[0075] In some embodiments, as shown in Figures 1 to 3 The driving rod 210 is a threaded rod and is vertically installed in the support cylinder 110, and the driving end of the driving member 220 is coaxially connected with the end of the driving rod 210 away from the support platform 100. The moving assembly 300 includes a moving cylinder 310 and a mounting plate 320. The moving cylinder 310 is fixedly connected with the mounting plate 320, the moving cylinder 310 is sleeved outside the support cylinder 110, the mounting plate 320 is inserted on the driving rod 210, and the mounting plate 320 is connected with the driving rod 210 through threads. The monitor 400 is installed on the mounting plate 320, and the protective cover 510 is detachably connected with the mounting plate 320.

[0076] In the embodiment of the present application, the connection relationship between the driving rod 210 and the moving assembly 300 is not limited and can be a gear and rack transmission. Specifically, in the present embodiment, the driving rod 210 is set as a threaded rod, and the connection relationship between the driving rod 210 and the moving assembly 300 is set as a threaded connection. By using the threaded connection, the overall structure of the monitoring device is more compact, and the ascending and descending of the moving assembly 300 together with the adjustment of the monitoring height of the monitor 400 is more accurate, which avoids the staff from repeatedly adjusting during use and facilitates the operation of the staff.

[0077] Meanwhile, the mobile assembly 300 is designed to be combined by the mobile cylinder 310 and the mounting plate 320, wherein the mobile cylinder 310 can ensure the stability of the mounting plate 320 during the lifting operation, thereby avoiding the problem that the monitor 400 is shaken left and right along with the mounting plate 320, and the clarity of the monitoring picture is reduced.

[0078] Further, in some embodiments, the protective cover 510 is provided with a connecting piece 511 on the end face of the mounting plate 320; the mounting plate 320 is provided with a plug-in hole 321, and the connecting piece 511 is inserted into the plug-in hole 321 to fix the relative position between the protective cover 510 and the mounting plate 320.

[0079] Here, the connecting mode between the protective cover 510 and the mounting plate 320 is designed to be a detachable connection of the connecting piece 511 and the plug-in hole 321, and the purpose is to facilitate the replacement work of the staff when the protective cover 510 is damaged.

[0080] Meanwhile, it can be understood that, in the embodiments of the present application, the number and arrangement density of the connecting piece 511 and the plug-in hole 321 are not limited, as long as the connecting piece 511 and the plug-in hole 321 are one-to-one corresponding, and the connection between the protective cover 510 and the mounting plate 320 is stable and reliable.

[0081] Referring to Figures 1 to 4 In some embodiments, the protective assembly 500 further comprises at least two clamping assemblies 520, each clamping assembly 520 is arranged on the opposite side of the protective cover 510, and each clamping assembly 520 can slide relative to the mounting plate 320, so that each clamping assembly 520 approaches or moves away from each other.

[0082] Since the mounting plate 320 will inevitably vibrate during the lifting operation, and if the protective cover 510 is accidentally detached, the lens surface of the monitor 400 will be easily contaminated with dust, affecting the clarity of the monitoring picture, therefore, in the above-mentioned embodiments, the clamping assembly 520 is arranged on the opposite side of the protective cover 510, to increase a layer of protection for the stable connection between the protective cover 510 and the mounting plate 320.

[0083] Further, in some embodiments, the mounting plate 320 is internally provided with a mounting groove 322; the clamping assembly 520 comprises a clamping arm 521 and a first elastic piece 522, the clamping arm 521 is inserted into the mounting groove 322, and the clamping arm 521 and the mounting plate 320 are connected through the first elastic piece 522, the clamping arm 521 can reciprocate between a first position and a second position, at the first position, the clamping arm 521 and the protective cover 510 are mutually buckled to fix the protective cover 510; at the second position, the clamping arm 521 releases the buckling relationship with the protective cover 510, and the first elastic piece 522 is compressed.

[0084] In a specific implementation, when the worker pulls the clamping arm 521 to release the buckling relationship with the protective cover 510, the first elastic member 522 is compressed and generates elastic force, and the clamping arm 521 has a movement tendency of returning from the second position to the first position under the elastic force from the first elastic member 522. After the worker replaces the protective cover 510, the clamping arm 521 is reset to the first position, thereby realizing automatic buckling with the protective cover 510 and simplifying the operation of the worker in installing the protective cover 510.

[0085] Meanwhile, it can be understood that the specific structure of the first elastic member 522 is not limited in the embodiments of the present application, and can be a spring or other types of elastic members, which can be selected and used by the worker according to actual conditions.

[0086] Further, in some embodiments, the outer part of the support cylinder 110 is provided with a top rod 600, and each clamping arm 521 is provided with an abutting inclined surface on the side surface thereof, and an insertion site is formed between each abutting inclined surface. The top rod 600 can be inserted into the insertion site and act on each abutting inclined surface, so as to make each clamping arm 521 move away from each other and compress the first elastic member 522.

[0087] In a specific implementation, when the worker is inconvenient to pull the clamping arm 521, the driving member 220 can be controlled to drive the driving rod 210 to rotate around the axis of the driving rod 210, thereby driving the mounting plate 320 to descend. After each clamping arm 521 inserted in the mounting plate 320 abuts against the top rod 600, the mounting plate 320 continues to descend, and at this time, the top rod 600 acts on the abutting inclined surface provided on the side surface of each clamping arm 521, so as to force each clamping arm 521 to move away from each other, thereby releasing the buckling relationship with the protective cover 510.

[0088] However, the side surface of each clamping arm 521 is provided as an inclined surface, and the top rod 600 is provided as a taper which is matched with the above inclined surface, so as to increase the contact area between the top rod 600 and each clamping arm 521, thereby making each clamping arm 521 move more stably under the action of the top rod 600.

[0089] In some embodiments, the clamping assembly 520 further comprises a grab ear 524 and a connecting plate 523, the grab ear 524 is connected with each clamping arm 521 through the connecting plate 523, and the grab ear 524 is located outside the mounting plate 320, so as to drive each clamping arm 521 to move away from each other through the grab ear 524 and compress the first elastic member 522.

[0090] Here, the grab ear 524 is provided, so as to facilitate the worker to pull each clamping arm 521.

[0091] In some embodiments, the mounting plate 320 is provided with a receiving groove 323; and the cleaning assembly 700 is further provided, which comprises a cleaning brush 710, a moving rod 720 and a second elastic member 730. The cleaning brush 710 is arranged at the end of the moving rod 720, the moving rod 720 is inserted into the mounting plate 320, and the moving rod 720 and the mounting plate 320 are connected through the second elastic member 730. The moving rod 720 can slide relative to the mounting plate 320 to drive the cleaning brush 710 to reciprocate between a third position and a fourth position. In the third position, the cleaning brush 710 is accommodated in the receiving groove 323; in the fourth position, the cleaning brush 710 extends outside the receiving groove 323 to contact the surface of the protective cover 510 and compress the second elastic member 730.

[0092] In the specific implementation, when the staff pushes the moving rod 720 to make the cleaning brush 710 extend outside the receiving groove 323, the second elastic member 730 is compressed and generates elastic force. After the moving rod 720 is subjected to the elastic force from the second elastic member 730, the moving rod 720 has a movement trend of driving the cleaning brush 710 to return from the fourth position to the third position. After the cleaning brush 710 finishes cleaning the surface of the protective cover 510, the moving rod 720 drives the cleaning brush 710 to reset to the third position, thereby realizing the automatic accommodation of the cleaning brush 710.

[0093] Similarly, it can be understood that in the embodiments of the present application, the specific structure of the second elastic member 730 is not limited, which can be a spring or other types of elastic members. The staff can select and use according to the actual situation

[0094] Further, in some embodiments, the outer portion of the supporting cylinder 110 is further provided with a top block 800, which can act on the end of the moving rod 720 away from the cleaning brush 710 to drive the cleaning brush 710 to extend outside the receiving groove 323.

[0095] In the specific implementation, when the staff cannot push the moving rod 720, the driving member 220 can be controlled to drive the driving rod 210 to rotate around its own axis, thereby driving the mounting plate 320 to descend. After the moving rod 720 inserted into the mounting plate 320 abuts against the top block 800, the mounting plate 320 continues to descend. At this time, the top block 800 acts on the end of the moving rod 720 away from the cleaning brush 710, forcing the moving rod 720 to drive the cleaning brush 710 to extend outside the receiving groove 323 to contact the surface of the protective cover 510 for cleaning.

[0096] Further, in some embodiments, the top block 800 and the supporting cylinder 110 are provided with a rotating member 900, so that the top block 800 can rotate relative to the supporting cylinder 110.

[0097] When the monitoring device is running and the surface of the protective cover 510 does not need to be cleaned, the top block 800 can be selected to expand the adjustable range of the monitoring height of the monitor 400.

[0098] It should be understood that the various forms of flow shown above can be used to reorder, add or delete steps. For example, the steps described in the embodiments of the present application can be executed in parallel, sequentially or in different orders, as long as the desired results of the technical solutions disclosed in the embodiments of the present application can be achieved, which are not limited herein.

[0099] The above specific embodiments do not constitute a limitation on the protection scope of the embodiments of the present application. Those skilled in the art should understand that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors.
