DETAILED DESCRIPTION

[0034] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Embodiment 1

[0036] See also Figure 1 - Figure 6 , the present application provides a slope monitoring and early warning device, comprising:

[0037] The monitoring and early warning structure 200 installed on the slope of the slope body 100 can monitor the soil layer changes inside the slope body 100, and transmit the monitored soil layer collapse and sinking changes to the terminal, so as to facilitate timely early warning of the slope body 100 changes, and at the same time protect the slope surface of the slope body 100, reduce the occurrence of large rocks sliding on the slope surface, and increase the safety of slope monitoring and early warning;

[0038] The monitoring and early warning structure 200 includes a plurality of mounting plates 202 which are mounted on the slope of the slope body 100, and the mounting plates 202 are fixed on the slope surface;

[0039] Multiple groups of anti-skid components 203 are arranged between two adjacent mounting plates 202 to stabilize the slope surface of the slope body 100. The anti-skid components 203 can be used to reinforce and protect the slope surface, and can be expanded or retracted as the mounting plates 202 move.

[0040] The mounting plate 202 is provided with a plurality of soil layer monitoring components 201 embedded in the slope body 100 to monitor soil layer collapse, and timely transmits the monitored soil layer changes to the terminal to issue an early warning.

[0041] In this embodiment, preferably, the soil layer monitoring component 201 includes an anchor pipe 2012 vertically passing through the mounting plate 202 and embedded in the slope surface of the slope body 100, the upper end of the anchor pipe 2012 is sleeved with a marking circle 2014 for locating the initial installation position, the anchor pipe 2012 is sleeved with a limiting circular plate 2015 located on the outer surface of the mounting plate 202, the diameter of the limiting circular plate 2015 is larger than the width of the rectangular sliding hole 205, and the upper end of the anchor pipe 2012 is sleeved with an elastic sleeve 201 fixed on the limiting circular plate 2015. 6. The elastic sleeve 2016 can be a rubber tube for easy deformation. A monitoring camera 2013 is arranged at the upper end of the anchor pipe 2012. The height of the monitoring camera 2013 extends beyond the displacement monitor 2011, which is convenient for monitoring the visible part of the slope. A displacement monitor 2011 is arranged on the upper surface of the mounting plate 202 and is located outside the marking circle 2014. The displacement monitor 2011 is used to monitor the displacement change between the limit circular plate 2015 and the marking circle 2014 and the angle change between the marking circle 2014 and the mounting plate 202.

[0042] In this embodiment, preferably, the anti-slip component 203 includes a plurality of fixed lugs 2031 arranged on the inner side of the mounting plate 202 and along its length direction, and a lower rotating plate 2032 and an upper rotating plate 2033 are rotatably arranged on two adjacent fixed lugs 2031. As the anti-slip component 203 is expanded or contracted, the rotation angles of the lower rotating plate 2032 and the upper rotating plate 2033 will change. The lower rotating plate 2032 and the upper rotating plate 2033 are cross-rotatably connected, and an intermediate rotating shaft 2034 is arranged between the two, so that the lower rotating plate 2032 and the upper rotating plate 2033 can be rotated. Several intermediate rotating shafts 2034 in the entire anti-slip component 203 are replaced by fixed rods 2035, which does not affect the rotating connection between the lower rotating plate 2032 and the upper rotating plate 2033, and makes it convenient to embed the fixed rods 2035 into the slope to fix the anti-slip component 203. The multiple lower rotating plates 2032 and the upper rotating plates 2033 are rotatably connected end to end to facilitate rotation close to each other. The lower rotating plates 2032 and the upper rotating plates 2033 are staggered up and down, and movable grooves are provided on the surfaces of the two to facilitate the two to be unfolded or retracted.

[0043] In summary, during installation, as the mounting plate 202 moves outward, the lower rotating plate 2032 and the upper rotating plate 2033 can be driven to rotate, and the angle with the vertical direction gradually becomes smaller, and the overall length of the anti-skid member 203 becomes longer. When the distance between adjacent mounting plates 202 is appropriate, the mounting plate 202 is fixed on the slope, and the overall installation length of each anti-skid member 203 is consistent, and the anti-skid member 203 is embedded in the slope through the fixing rod 2035, and the anchor pipe 2012 passes through the mounting plate 202 and is embedded in the slope, and the limiting circular plate 2015 contacts the outer surface of the mounting plate 202. At this time, the initial position of the marking circle 2014 on the anchor pipe 2012 is recorded. If the slope body 100 is deformed or collapsed along the slope direction, the soil position change acts on the anchor pipe 2012. On the pipe 2012, the pressure causes the anchor pipe 2012 to have a certain displacement change, and the distance between the marking circle 2014 and the mounting plate 202 changes. The change of the anchor pipe 2012 causes the limiting circular plate 2015 to be forced to move along the anchor pipe 2012, and the elastic sleeve 2016 is subjected to pressure. The distance between the marking circle 2014 and the mounting plate 202 changes, and the distance change is monitored by the displacement monitor 2011, and the monitored displacement change is transmitted to the terminal, so as to facilitate early warning of the displacement change, monitor the deformation of the soil layer inside the slope body 100, and at the same time, use multiple sets of unfolded anti-skid components 203 to compact and protect the slope surface, increase the stability of the slope surface, reduce the danger caused by landslides, and increase the monitoring safety of the slope body 100.

[0044] Embodiment 2

[0045] Reference Figure 7 , which is the second embodiment of the present invention.

[0046] In this embodiment, preferably, a rectangular sliding hole 205 is opened on the mounting plate 202 for the anchor pipe 2012 to pass through, which is convenient for the installation of the anchor pipe 2012. The upper and lower ends of the mounting plate 202 are fixed to the slope surface of the slope body 100 by anchor rods 204. The anchor rods 204 also have a pointed end to facilitate embedding into the slope body 100.

[0047] In this embodiment, preferably, a deformation monitoring component 206 for monitoring the deformation of the slope surface of the slope body 100 is provided on the upper surface of the anti-slip component 203, and multiple groups of deformation monitoring components 206 can be provided on multiple groups of anti-slip components 203, and the deformation monitoring components 206 are distributed along the length direction of the anti-slip component 203. The initial installation length of the anti-slip component 203 is fixed, and the initial position is limited by the deformation rope 2065. If the slope body 100 is deformed and cracked along the unfolding direction of the anti-slip component 203, it will be transmitted to the anti-slip component 203, and the deformation rope 2065 on the anti-slip component 203 will be pulled or even broken, and the force on the deformation rope 2065 will be monitored by the tension sensor 2065, and the signal will be sent to the terminal The conveying sends out an early warning, the deformation monitoring component 206 includes an extension plate 2061 fixed on the upper rotating plate 2033, and each extension plate 2061 is provided with two tension sensors 2064 on the upper surface, and the tension sensor 2064 clamps a support rod 2062, and the lower end of the support rod 2062 can be rectangular, which is convenient for being clamped and fixed by the tension sensor 2064, and the tension sensors 2064 on the two adjacent extension plates 2061 are relatively distributed, and when the anti-slip component 203 is abnormally unfolded, the two relatively distributed tension sensors 2064 can pull and detect the two ends of the deformation rope 2065, and a winding wheel 2063 is provided on the support rod 2062, and a deformation rope 2065 is provided between the two adjacent winding wheels 2063.

[0048] In this embodiment, preferably, the winding wheel 2063 is an H-shaped structure, and the winding wheel 2063 is installed horizontally. The outer end of the deformable rope 2065 can be wrapped around the middle position of the winding wheel 2063 for multiple turns, so that the tightness of the winding on the two winding wheels 2063 can be adjusted according to the position between the two extension plates 2061, thereby adapting to the length of the entire anti-slip component 203.

[0049] In summary, when in use, the two adjacent mounting plates 202 are stretched to a suitable length. At this time, one end of the deformable rope 2064 is wound around the winding wheel 2063, while the other end is not wound. As the two mounting plates 202 are stretched outward, the anti-skid component 203 is gradually unfolded until the two mounting plates 202 are fixed on the slope surface of the slope body 100, and the position of the anti-skid component 203 is fixed. At the same time, the fixing rod 2035 in the anti-skid component 203 is embedded in the slope surface, which fixes the position of the anti-skid component 203 and does not cause abnormal expansion or contraction. At this time, the other end of the deformable rope 2065 is wound around another winding wheel 2063, and the lengths of the two winding wheels 2063 are recorded. Initial distance and position. If cracks appear on the slope along the length direction, the positions of the fixed rods 2035 on both sides of the cracks will be offset, and the offset of the fixed rods 2035 will drive the lower rotating plate 2032 and the upper rotating plate 2033 connected thereto to change their positions and rotate, thereby driving the position of the winding wheel 2063 installed on the upper rotating plate 2033 to change, and the distance between the two winding wheels 2063 changes, so that the deformable rope 2065 wrapped around the two is pulled due to the position change, and the pulling force is transmitted to the winding wheel 2063 and the support rod 2062, and is detected by the tension sensor 2064, which transmits the detected force to the terminal and issues an early warning.

[0050] Embodiment 3

[0051] Reference Figure 8 and Fig. 9 , which is the third embodiment of the present invention.

[0052] In this embodiment, preferably, a pressure monitoring component 207 is provided inside the anchor pipe 2012. By cooperating the pressure monitoring component 207 with the anchor pipe 2012, it can not only be firmly embedded in the slope, but also detect the sinking or collapse of the slope in the vertical direction, and transmit the detected pressure outward, so as to facilitate timely monitoring of the vertical sinking pressure of the slope and early warning, thereby increasing the comprehensiveness of the slope monitoring. A perforation 2071 is provided on the upper surface of the lower end of the anchor pipe 2012, and the perforation 2071 can facilitate the filling of the soil inside, and record the initial pressure of the filled soil. A pressure sensor 2072 is arranged inside the tube 2012 and is located on the inner side of the perforation 2071. A sensing contact 2075 is arranged on the surface of the pressure sensor 2072. A protective baffle 2073 is arranged on the inner side of the perforation 2071. A spherical block 2074 in contact with the sensing contact 2075 is arranged on the lower surface of the protective baffle 2073. The spherical block 2074 can be subjected to pressure and contact the sensing contact 2075 for detection. A plurality of buffer members 2076 are arranged circumferentially between the protective baffle 2073 and the pressure sensor 2072 to facilitate buffering the pressure on the protective baffle 2073.

[0053] In this embodiment, preferably, the anchor pipe 2012 is hollow and has a tapered lower end, which is convenient for installing the pressure monitoring component 207 and embedding it into the slope, thereby increasing the installation strength and stability of the anchor pipe 2012.

[0054] In summary, the pressure monitoring component 207 can be installed inside the anchor pipe 2012 and located on the inner side of the perforation 2071. When the anchor pipe 2012 is embedded in the slope body 100, during the installation process, the soil passes through the perforation 2071 and fills the inside. After the anchor pipe 2012 is installed, the filled soil exerts an initial pressure on the protective baffle 2073, and the initial pressure drives the protective baffle 2073 to contact the sensing contact 2075. The pressure sensor 2072 records the initial pressure. If the slope sinks or collapses in the vertical direction, the soil will squeeze the soil inside the anchor pipe 2012 and transfer the pressure to the protective baffle 2073, and transfer the pressure to the sensing contact 2075 again. The pressure sensor 2072 detects the changed pressure and transfers the changed pressure to the terminal, judges the pressure change value, and issues an early warning of the pressure change, thereby expanding the monitoring range of the slope.

At the same time, the anti-slip component 203 fits the slope surface for compression and protection. While providing protection, the deformation monitoring component 206 can be used to monitor the deformation and cracking in the lateral direction of the slope surface, and the pressure monitoring component 207 can be used to monitor the vertical soil layer changes inside the slope.
