Description

Technical Field

[0001] The invention relates to the technical field of rock mass monitoring, and in particular to a dangerous rock mass fracture monitoring device. Background Art

[0002] Unstable rock mass is a dangerous rock mass usually located on the outer layer or inner part of a steep slope (at a higher position than the road). The rock mass is affected by factors such as river scouring, groundwater activity, rainwater soaking, earthquakes and artificial slope cutting, and the stress state of the slope changes. When the sliding force or overturning force reaches or even exceeds the anti-sliding force or anti-overturning force and loses balance, it will be damaged and cause geological disasters such as displacement, deformation, sliding and collapse. Once a disaster occurs, it is very likely to affect vehicles on the road at the foot of the mountain. Therefore, when monitoring the rock mass, a GNSS displacement monitoring station will be used to monitor it in real time.

[0003] The GNSS displacement monitoring station is mainly composed of GNSS antenna, solar panel, main control box (with main control transmission module) and mounting bracket. It includes two parts: base station and measuring station. The equipment can upload data to the environmental monitoring platform through 4G signal network. It is suitable for surface displacement monitoring and building deformation monitoring, such as landslide, slope displacement, dangerous rock, bridge deformation, reservoir dam, mining geological disasters, etc.

[0004] The main function of the solar panels on the GNSS displacement monitoring station is to provide a stable and continuous power supply to ensure that the equipment can work normally under various environmental conditions.

[0005] A Chinese patent with application number CN202110786594.3 discloses a comprehensive slope monitoring and early warning platform, including a monitoring station, the monitoring station includes a base and a pole, the pole is arranged on the base, a meteorological monitor is arranged on the top of the pole, and a photovoltaic panel and a control box are arranged on the pole; the monitoring terminal includes a fixed terminal and a mobile terminal, and the control box is connected to the fixed terminal and the mobile terminal by signal; the platform can monitor the slope for a long time, grasp the deformation characteristics and development laws of the slope, and provide accurate data support for researchers to study the critical conditions, scale, displacement direction, instability mode, hazard size of slope geological disasters, and timely forecast slope instability or sudden geological disasters; GNSS displacement monitoring stations are generally installed outside and exposed to the air, and the solar panels installed on the GNSS displacement monitoring stations are also exposed to the air. In the natural environment, wind is one of the main forces for the formation of dust. Strong winds can blow up soil, sand and other tiny particles on the ground. These particles may then adhere to the solar panels due to the gravitational force of the wind. At night, the surface temperature usually drops, and water vapor in the air condenses into dew when it encounters a colder surface. If the GNSS displacement monitoring station is exposed to a low temperature environment at night, dew is likely to form on its surface. During the use of the above-mentioned device, when the dew and dust on the surface of the solar panel exposed to the air are mixed, mud will be formed and adhere to the surface of the solar panel. When the solar panel containing mud is exposed to the sun, a shadow area will appear on the surface of the solar panel, which can easily cause hot spots on the solar panel, thereby accelerating the damage of the solar panel.

[0033] The following will refer to the attached Figures 1 to 12 The embodiments of the present invention are described in detail. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0034] Embodiment 1 Since strong winds can blow up soil, sand and other tiny particles on the ground, these particles may then adhere to the solar panel 12 due to the attraction of the wind. At night, the surface temperature usually drops, and water vapor in the air condenses into dew when it encounters a colder surface. If the displacement monitoring device 1 is exposed to a low temperature environment at night, dew is likely to form on its surface. When the dew and dust on the surface of the solar panel 12 are mixed, mud will be formed. When the solar panel 12 containing mud is exposed to the sun, a shadow area will appear on the surface of the solar panel 12, which can easily cause the solar panel 12 to have a hot spot phenomenon, thereby easily accelerating the damage of the solar panel 12.

[0037] The cleaning assembly 20 includes two connecting frames 21 symmetrically fixed at the bottom of the sealing plate 111, the interiors of the two connecting frames 21 are each provided with a first sliding plate 22, the tops of the two first sliding plates 22 are respectively slidably connected to the inner top walls of the corresponding connecting frames 21, the bottoms of the two connecting frames 21 are each provided with a first sliding opening 23, the two first sliding plates 22 are respectively slidably connected to the interiors of the corresponding first sliding openings 23, the two first sliding plates 22 are each provided with a first through hole 24, a rotating shaft 25 is provided between the two connecting frames 21, and the outer walls at both ends of the rotating shaft 25 are respectively rotatably connected to the inner walls of the corresponding first through holes 24, and the diameter value of the first through hole 24 is greater than the diameter value of the rotating shaft 25, the two connecting frames 21 are each provided with a second sliding opening 26 on one side facing the rotating shaft 25, and the two ends of the rotating shaft 25 are respectively located inside the corresponding second sliding opening 26, and the diameter value of the rotating shaft 25 is less than the height value of the second sliding opening 26, and the surface of the rotating shaft 25 is provided with a first cleaning member 27, in this embodiment, the first cleaning member 27 is a cylindrical sponge.

[0038] The first slide rails 28 are fixed on both sides of the inner wall of the housing 11. The first slide rails 28 have an oblique section and a straight section. The top of the oblique section is higher than the bottom, and the top of the oblique section is connected to one end of the straight section. The insides of the two first slide rails 28 are slidably connected with first sliding shafts 29. One end of the two first sliding shafts 29 is respectively fixed on a side wall of the corresponding first sliding plate 22, and the initial position of the first sliding shaft 29 is located at the bottom end of the oblique section. A support plate is provided on one side of the bottom end of the two first sliding plates 22. 210, and one side of the first sliding plate 22 is slidably connected to a side wall of the support plate 210, a driving sleeve 211 is fixed between the two support plates 210, a reciprocating screw 212 is provided inside the driving sleeve 211, and the driving sleeve 211 is slidably connected to the reciprocating screw 212, and one end of the reciprocating screw 212 is rotatably connected to the inner wall of the outer shell 11, a driving source 213 is installed outside the outer shell 11, and the output end of the driving source 213 passes through the outer shell 11 and is fixed to one end of the reciprocating screw 212.

[0039] Since the displacement monitoring device 1 is a GNSS displacement monitoring station, which belongs to the prior art, it will not be described again. When in use, the displacement monitoring device 1 is installed at the monitoring dangerous rock to monitor the dangerous rock at all times. When the displacement monitoring device 1 detects that the dangerous rock has landslided or the cracks in the dangerous rock have increased, an alarm will be issued to remind the staff. The solar panel 12 is used to absorb light energy and convert it into electrical energy to power the monitoring tools on the displacement monitoring device 1. When the solar panel 12 is cleaned, the working time of the driving source 213 can be controlled by the control system. The end of the reciprocating screw 212 close to the driving source 213 is the head end, and the other end is the tail end. When the output end of the driving source 213 drives the reciprocating screw 212 to rotate, the driving sleeve 211 slides from the head end of the reciprocating screw 212 to its tail end. The driving sleeve 211 drives the first sliding plate 22 through the support plate 210 to slide from the head end of the first slide rail 28 to its tail end, and the first sliding shaft 29 slides from the bottom end of the oblique section to its top end to the inside of the straight section.

[0040] When the first sliding shaft 29 slides from the bottom end of the oblique section to the top end thereof, the two first sliding plates 22 drive the connecting frame 21 to move out of the first opening 110, so that the connecting frame 21 is located above the housing 11, and the first cleaning member 27 is also located above the solar panel 12. When the first sliding shaft 29 slides to the end of the straight section, the first cleaning member 27 can clean the surface of the solar panel 12. When the driving sleeve 211 slides to the end of the reciprocating screw 212, the first sliding shaft 29 also slides to the end of the straight section. As the reciprocating screw 212 moves, the first sliding shaft 29 moves to the end of the straight section. Rotate, the drive sleeve 211 slides from the tail end of the reciprocating screw 212 to its head end, and the first sliding shaft 29 slides from the straight section to the oblique section. At this time, the first cleaning member 27 can clean the solar panel 12 again, and the first sliding shaft 29 slides from the top of the oblique section to the bottom end. The first sliding plate 22 drives the sealing plate 111 to move down into the first opening 110 through the connecting frame 21. When the first sliding shaft 29 is located at the bottom end of the oblique section, the outer surface of the housing 11 and the outer surface of the sealing plate 111 are again located on the same horizontal plane.

[0041] The reciprocating screw 212 drives the driving sleeve 211 to slide back and forth along the axial direction of the reciprocating screw 212, and the first sliding shaft 29 slides along the extended track of the first sliding rail 28, so that the sealing plate 111 and the sealing plate 111 can be moved up to the top of the outer shell 11, so that the first cleaning piece 27 on the rotating shaft 25 can clean the surface of the solar panel 12, and when the sealing plate 111 moves down, the connecting frame 21 and the first cleaning piece 27 can move down into the interior of the outer shell 11, thereby preventing the solar panel 12 from being shadowed when exposed to sunlight.

[0042] Through the cooperation of the first slide rail 28, the first sliding shaft 29, the support plate 210, the drive sleeve 211 and the reciprocating screw 212, the sealing plate 111 slides up and down inside the shell 11. When the solar panel 12 is cleaned, the sealing plate 111 and the connecting frame 21 are moved out of the shell 11, so that the first cleaning member 27 cleans the surface of the solar panel 12. When the solar panel 12 is cleaned, the sealing plate 111 and the connecting frame 21 are moved down again into the shell 11 to prevent the solar panel 12 from generating a shadow area when exposed to the sun.

[0043] refer to Figure 6 , Figure 8 , Fig. 9 , Fig.10 and Fig.11 As shown, an adjusting assembly 30 is provided inside the connecting frame 21 for adjusting the cleaning direction of the solar panel 12 by the first cleaning member 27 .

[0044] The adjusting assembly 30 includes two first linkage shafts 31, and the two first linkage shafts 31 correspond to a first sliding plate 22 respectively. The outer surfaces of the two first linkage shafts 31 are installed with linkage gear rings 32, and the inner top wall and the inner bottom wall of the connecting frame 21 are respectively installed with an upper rack 33 and a lower rack 34, the upper rack 33 is located above the first linkage shaft 31, and the lower rack 34 is located below the first linkage shaft 31, and the upper rack 33 is meshed and connected with the linkage gear ring 32, and the upper rack 33 and the lower rack 34 are staggered and arranged inside the connecting frame 21, and the two first linkage shafts 31 are fixed with a limiting plug 35 on one side facing the corresponding first sliding plate 22, and both ends of the rotating shaft 25 are provided with limiting grooves 36 matched with the limiting plug 35, and the limiting plug 35 is inserted into the corresponding limiting groove 36.

[0045] The first linkage shaft 31 is rotatably connected to the side away from the first sliding plate 22 with the second linkage shaft 37, and the second linkage shaft 37 is provided with a third linkage shaft 38 on the side away from the first linkage shaft 31, and the third linkage shaft 38 is composed of a thick cylinder and a thin cylinder, and one end of the thick cylinder is fixed to one end of the thin cylinder, and one end of the thick cylinder is slidably connected to the inner wall of the connecting frame 21, and the second linkage shaft 37 is provided with a circular groove adapted to the thin cylinder on the side facing the thin cylinder, and the thin cylinder is slidably connected inside the circular groove. The inner top walls and the inner bottom walls of the two connecting frames 21 are respectively installed with limit shells 39, and the two limit shells 39 are symmetrically installed inside the connecting frame 21. The limit shell 39 is provided with a slide groove 310 on the side facing the second linkage shaft 37, and the slide groove 310 is annular, and the two turning points of the slide groove 310 both have inclined surfaces. Two symmetrical second sliding shafts 311 are fixed to the outer surface of the second linkage shaft 37, and the second sliding shaft 311 is slidably connected to the inside of the corresponding slide groove 310.

[0046] When the first sliding shaft 29 slides along the track of the first slide rail 28, the linkage gear ring 32 of the first linkage shaft 31 is meshed and connected with the upper rack 33. At this time, the first linkage shaft 31 drives the connected rotating shaft 25 to rotate through the limiting plug block 35. When the first sliding shaft 29 slides from the head end of the first slide rail 28 to its tail end, the rotation direction of the rotating shaft 25 is counterclockwise. At this time, the first cleaning member 27 is outwardly rotated to clean the surface dirt of the solar panel 12. When the first sliding shaft 29 slides to the tail end of the first slide rail 28, the second sliding shaft 311 is bent by the slideway groove 310. The guide of the inclined surface can enter the other groove of the slide groove 310 away from the first linkage shaft 31. At this time, the thin cylinder slides inside the circular groove. Since the tooth positions of the upper rack 33 and the lower rack 34 correspond to each other, the first linkage shaft 31 can be disengaged from the upper rack 33 and the lower rack 34 and meshed and connected again with the drive of the second sliding shaft 311. Then, when the first sliding shaft 29 slides from the tail end of the first slide rail 28 to its head end, the first linkage shaft 31 drives the rotating shaft 25 to rotate clockwise. At this time, the first cleaning member 27 rotates inward to clean the dirt on the surface of the solar panel 12 again.

[0047] By cooperating with the linkage gear ring 32, the upper rack 33, the lower rack 34, the slide groove 310 and the second sliding shaft 311, the rotation direction of the rotating shaft 25 can be controlled, thereby preventing the rotating shaft 25 from driving the first cleaning member 27 to squeeze the dirt on the surface of the solar panel 12 when cleaning the solar panel 12, thereby preventing the surface of the solar panel 12 from being hard damaged.

[0048] Embodiment 2 When the first cleaning member 27 cleans the surface of the solar panel 12, the dirt on the surface of the solar panel 12 will adhere to the surface of the first cleaning member 27. If the dirt attached to the surface of the first cleaning member 27 is not cleaned in time, the first cleaning member 27 will cause the attached dirt to be squeezed onto the surface of the solar panel 12, which may easily damage the solar panel 12, and the dirt will adhere to the surface of the solar panel 12 again. In view of this, improvements are made based on the first embodiment.

[0049] refer to Figure 6 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 and Fig.12 As shown, a scraping assembly 40 is provided on the rotating shaft 25 for cleaning dirt attached to the surface of the first cleaning member 27 , thereby maintaining the cleaning performance of the first cleaning member 27 on the solar panel 12 .

[0050] The scraping assembly 40 includes two concave cylinders 41 that are respectively slidably connected to the corresponding connecting frames 21, and a receiving hole 42 is opened in the middle of the two concave cylinders 41, and the outer surface of the rotating shaft 25 is rotatably connected to the inner wall of the receiving hole 42. A limiting slider 43 is fixed on the side of the two concave cylinders 41 facing the corresponding connecting frame 21, and a limiting groove 44 is opened on the side of the two connecting frames 21 facing the connected concave cylinders 41, and the limiting slider 43 is slidably connected inside the corresponding limiting groove 44.

[0051] The surfaces of the two concave cylinders 41 are each provided with two symmetrical side plates 45, and the side plates 45 are in an arc shape. A second cleaning piece 46 is fixed between the two side plates 45 located at the head and tail ends of the rotating shaft 25. The second cleaning piece 46 is inclined, and the two second cleaning pieces 46 are symmetrical with the first cleaning piece 27 as the center. The interior of the second cleaning piece 46 has a accommodating cavity, and the top of the second cleaning piece 46 is formed with a tip, and the tip is close to the first cleaning piece 27. The second cleaning piece 46 has an arc-shaped surface facing the first cleaning piece 27, thereby adapting to the shape of the first cleaning piece 27.

[0052] The outer surfaces of the two concave cylinders 41 are each provided with two symmetrically staggered sliding openings 47, each sliding opening 47 is slidably connected to a sliding block 48, and one side of the sliding block 48 is fixed to the inner wall of the corresponding side plate 45, a first return spring 49 is fixed between each side plate 45 and the connected concave cylinder 41, a third sliding opening 410 is provided at both ends of the rotating shaft 25, and a linkage block 411 is slidably connected to the inside of the third sliding opening 410, an outer ring 412 is provided at both ends of the rotating shaft 25, the outer ring 412 has an arc surface, and the outer ring 412 is located inside the corresponding concave cylinder 41, and the inner wall of the outer ring 412 is fixed to one side of the linkage block 411.

[0053] Since the two second cleaning pieces 46 are respectively located on the left and right sides of the rotating shaft 25, when the first sliding shaft 29 slides along the head end of the first sliding rail 28 to its tail end, the rotating shaft 25 drives the first cleaning piece 27 to rotate counterclockwise. At this time, the arc surface of the outer ring 412 presses against the sliding block 48 located on the right side of the second cleaning piece 46, so that the second cleaning piece 46 on the right side of the rotating shaft 25 is away from the first cleaning piece 27, and the second cleaning piece 46 on the left side of the rotating shaft 25 is close to the surface of the first cleaning piece 27 to scrape the dirt on its surface, and the dirt scraped off by the tip of the second cleaning piece 46 will flow into the interior of the accommodating cavity along the tip.

[0054] When the second sliding shaft 311 slides into the other groove of the slideway groove 310 away from the first sliding plate 22, and the linkage gear ring 32 is meshed and connected with the lower rack 34, the rotating shaft 25 drives the first cleaning member 27 to rotate from counterclockwise to clockwise, and the second linkage shaft 37 pulls the linkage block 411 to slide inside the third sliding opening 410 through the first linkage shaft 31 and the limiting plug block 35, so that the outer ring 412 slides along the extension track of the third sliding opening 410, and the sliding block 48 located on the right side of the rotating shaft 25 is separated from the outer ring 412 is limited, and the side plate 45 on the right side of the rotating shaft 25 is reset by the first reset spring 49, so that the second cleaning piece 46 on the right side is tightly attached to the surface of the first cleaning piece 27, and the sliding block 48 on the left side of the rotating shaft 25 is pushed by the outer ring 412 to drive the second cleaning piece 46 on the side plate 45 away from the first cleaning piece 27, and the side plate 45 will pull the first reset spring 49, so that along the rotation direction of the rotating shaft 25, the two second cleaning pieces 46 are alternately attached to the first cleaning piece 27 to clean its surface.

[0055] Through the cooperation of the concave cylinder 41, the side plate 45, the second cleaning piece 46, the sliding block 48, the first return spring 49, the linkage block 411 and the outer ring 412, the two second cleaning pieces 46 can slide alternately and close to the surface of the first cleaning piece 27 along the rotation direction of the rotating shaft 25, thereby cleaning the dirt on the surface of the first cleaning piece 27 and maintaining the cleaning performance of the first cleaning piece 27.
