Description

Technical Field

[0001] This invention relates to the field of early warning and monitoring technology, and in particular, to a slope monitoring and early warning device. Background Technology

[0002] With the development of road transportation, the mileage of roads has increased significantly. In road construction, it is often necessary to build roads in mountainous and forested areas. To avoid landslides, slopes are usually built on both sides of the road to reduce the risk. However, over time, and due to the impact of heavy rain and earthquakes, slope safety has become a concern. To improve slope safety, monitoring and early warning devices are installed on slopes to monitor their stability. However, slope monitoring and early warning devices are usually installed and fixed by inserting support legs into the load-bearing structure. This installation method results in a small contact area between the device and the load-bearing structure, leading to poor installation stability. Summary of the Invention

[0042] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0043] 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 a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0044] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0045] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this invention.

[0046] Please refer to Figures 1 to 3 A preferred embodiment of the present invention provides a slope monitoring and early warning device, comprising a monitoring and alarm instrument body, a support leg 200, a height position fixing component 300, an adhesive plate 400, a tightening component 500, and a cover plate 600.

[0047] The monitoring and alarm device is equipped with or connected to sensors to monitor the slope condition. When slope instability and landslides occur, the sensors detect the movement and send an alarm signal to a remote control station, enabling remote monitoring. For example, the sensor could be a level. Initially, the monitoring and alarm device is installed in a level or near-level position. When slope instability and landslides occur, the device will tilt or fall, changing its angle. The level will detect this change and send an alarm signal. Alternatively, the monitoring and alarm device can be a combination of multiple devices, such as a weather monitor, soil moisture meter, level, and piezometer, to monitor the slope. These instruments connect to the monitoring and alarm device's control system to transmit monitoring data, achieving comprehensive slope monitoring.

[0048] The monitoring alarm device includes a housing 100, which has an upper opening and a receiving cavity. Connecting posts 110 are provided at the four corners of the outer periphery of the housing 100. The bottom of the support leg 200 is provided with an insertion part 210 for inserting into the bearing structure 101. The bearing structure 101 can be a compacted soil layer on the slope surface or a concrete structure poured on the slope surface.

[0049] The bottom of the insertion part 210 is conical. The upper end of the support leg 200 is provided with a socket 220 that matches the partial outline of the connecting post 110. Specifically, the connecting post 110 is a cylinder, and the basic outline of the socket 220 is a circular hole that matches the connecting post 110. The connecting column 110 is inserted into the insertion hole 220, so that the support leg 200 is sleeved on the bottom of the connecting column 110. The support leg 200 can move up and down along the connecting column 110 to adjust its height to adapt to different slope inclinations. The height position fixing component 300 is sleeved on the connecting column 110 and can move up and down along the connecting column 110 to adjust its position, thereby adapting to the height adjustment of the support leg 200. The height position fixing component 300 is used to fix the height position of the support leg 200. The bonding plate 400 is rotatably installed on the support leg 200 and can move up and down along the support leg 200. The bonding plate 400 is used to fit with the load-bearing structure. The bottom of the bonding plate 400 is provided with an anchor insertion column 410 for inserting into the load-bearing structure. The clamping component 500 is installed on the connecting column 110. The clamping component 500 can move up and down to adjust its position so that its lower end presses against the bonding plate 400. The cover plate 600 is placed on top of the receiving cavity.

[0050] The present invention discloses a slope monitoring and early warning device. The bottom of the support leg 200 can be inserted into the bearing structure 101 (the slope surface) for installation. The bonding plate 400 contacts the bearing structure 101, increasing the contact area. Anchor posts 410 are inserted into the bearing structure 101, further improving the connection stability. The bonding plate 400 can rotate to adapt to the angle of the bearing structure 101, ensuring a tight fit and installation stability. The support leg 200 can move up and down along the connecting post 110, thereby achieving height adjustment and allowing each support leg 200 to be adjusted to the required height, improving the device's adjustability and adaptability. The height fixing component 300 fixes the height of the support leg 200, ensuring stable position after installation. The clamping component 500 presses the bonding plate 400, keeping it in contact with the bearing structure 101. The height position fixing component 300 and the top clamping component 500 ensure that the support leg 200 and the bonding plate 400 are in a stable state after the position is adjusted, making the state device structure tight and stable and not loose.

[0051] like Figure 2 As shown, in order to obtain continuous energy to power the electronic equipment inside the monitoring and alarm device, in some embodiments, a solar panel 650 may be installed on the top of the cover 600, and a rechargeable battery is installed inside the receiving cavity. The solar panel 650 converts the obtained solar energy into electrical energy and charges the rechargeable battery, thereby improving the battery life of the monitoring device.

[0052] Reference Figure 4 and Figure 6To facilitate height adjustment of the support leg 200, in some embodiments of the present invention, the upper peripheral wall of the insertion hole 220 is provided with a protrusion 221, the peripheral wall of the connecting column 110 is provided with a vertically extending vertical groove 111, and the side wall of the vertical groove 111 is provided with a plurality of horizontally arranged slots 112; the protrusion 221 can slide vertically along the vertical groove 111 and can be rotated into one of the horizontal slots 112. By inserting the protrusion 221 into the horizontal slots 112 of different heights, the height of the support leg 200 can be adjusted; the height position fixing member 300 includes a collar 310 slidably sleeved on the connecting column 110 and a locking block 320 provided in the inner ring of the collar 310. The locking block 320 extends vertically downward and protrudes from the collar 310. The locking block 320 is embedded in the vertical groove 111 and can slide up and down along the vertical groove 111. Figure 10 As shown, when the protrusion 221 is engaged in one of the transverse slots 112 and the collar 310 is in contact with the upper end of the support leg 200, the locking block 320 can block the movement path of the protrusion 221 from leaving the transverse slot 112, thus fixing the height position of the support leg 200. When the protrusion 221 is engaged in the transverse slot 112, it avoids the lifting movement path of the locking block 320. Under the action of gravity, the locking block 320 will fall until the collar 310 is in contact with the upper end of the support leg 200. At this time, the locking block 320 is located on the side of the transverse slot 112, preventing the protrusion 221 from leaving the transverse slot 112, thereby firmly locking the protrusion 221 in the transverse slot 112. In addition, to prevent the locking block 320 from rotating into the transverse slot 112, the vertical length of the transverse slot 112 is greater than the horizontal slot 112. In addition, for structural stability, four vertical slots 111 and protrusions 221 are evenly arranged around the axis of the connecting column 110, thereby achieving multi-position locking. When it is necessary to adjust the height of the support leg 200, the collar 310 can be lifted upwards, so that the locking block 320 does not limit the protrusion 221, achieving the desired effect. Figure 11 In the state shown, the support leg 200 can be rotated to allow the protrusion 221 to enter the vertical groove 111. Then, the height of the support leg 200 can be adjusted by raising and lowering until the protrusion 221 is engaged in the horizontal groove 112 at the required height. After the protrusion 221 is engaged in the horizontal groove 112, the locking block 320 automatically falls back to limit the protrusion 221 again.

[0053] Reference Figure 2 , Figure 10 and Figure 11In a further embodiment of the present invention, the slope monitoring and early warning device further includes a spring 700, which is sleeved on the connecting column 110. The spring 700 is used to apply a downward force to the collar 310. Specifically, the spring 700 is a compression spring. The spring 700 ensures that when the locking block 320 is not blocked by the protrusion 221, the collar 310 can automatically fall back to be in contact with the upper end of the support leg 200, thereby limiting the locking block 320 to the protrusion 221 and ensuring that the collar 310 remains in contact with the upper end of the support leg 200, so that the locking block 320 maintains its limitation on the protrusion 221 and ensures the stability of the structure.

[0054] Reference Figure 6 In a further embodiment of the present invention, the bonding plate 400 has a clearance hole 401 at its center, and a hinge ball 420 is provided at the center of the clearance hole 401. The hinge ball 420 is connected to the bonding plate 400 through a connecting rod 430. The hinge ball 420 is embedded in the insertion hole 220 and can rotate around its own center. The peripheral wall of the insertion hole 220 has a clearance notch 222 with an upper opening corresponding to the connecting rod 430. The width of the clearance notch 222 is greater than the width of the connecting rod 430, and the connecting rod 430 can move vertically within the clearance notch 222. The diameter of the insertion hole 220 is adapted to the hinge ball 420, thereby allowing the bonding plate 400 to rotate around the hinge ball 420. The clearance hole 401 allows the bonding plate 400 to have a large range of motion when rotating, reducing structural interference with the support leg 200. In addition, the width of the clearance notch 222 is greater than the width of the connecting rod 430, which also allows the connecting rod 430 to rotate vertically in the clearance notch 222 and also rotate a certain angle along its own axis. Specifically, there are four connecting rods 430, evenly arranged in a circular pattern to minimize structural interference during rotation. Alternatively, to prevent structural interference, the connecting rods 430 can also be round rods. Of course, the slope angle is usually designed within a certain range, and the range of motion of the mating plate 400 only needs to meet the design requirements. Understandably, to facilitate installation, the hinge ball 420 has a cutout 421 on its peripheral wall corresponding to the protrusion 221.

[0055] Reference Figure 6 In a further embodiment of the present invention, the connecting post 110 is provided with a vertically extending threaded hole 113 at its center, and the clamping member 500 is a screw threaded to the threaded hole 113. The screw can be screwed to adjust its height to abut against the hinge ball 420. The screw can be height-adjusted to adapt to the height of the hinge ball 420. After the screw is adjusted, it is not easy for it to automatically rise and fall to change its position. In order to facilitate screwing, both ends of the screw are provided with polygonal grooves to facilitate tool screwing operation.

[0056] Reference Figure 5In a further embodiment of the present invention, four clearance recesses 120 are provided at the four corners of the outer periphery of the housing 100. A connecting post 110 is fixedly installed on the top wall of the clearance recess 120. The connecting post 110 can be fixedly installed on the top wall of the clearance recess 120 by welding or fasteners. The top wall of the clearance recess 120 is provided with a positioning hole 130 whose contour is larger than that of the threaded hole 113. Specifically, the threaded hole 113 and the positioning hole 130 are coaxially arranged, with the upper end of the threaded hole 113 protruding from the positioning hole 130 to facilitate the connection between the clamping member 500 and the positioning hole 113. Positioning posts 800 are installed at the four corners of the bottom of the cover plate 600. The positioning posts 800 are inserted into the positioning holes 130. Through the cooperation of the positioning posts 800 and the positioning holes 130, the positioning installation of the cover plate 600 is achieved. Additionally, it also serves to shield and hide the threaded hole 113, reducing the risk of rusting.

[0057] Reference Figure 5 , Figure 7 , Figure 8 and Figure 9 In a further embodiment of the present invention, a retaining ring 140 is movably sleeved on the upper end of the connecting post 110, and a positioning post 800 is rotatably mounted on the bottom of the cover plate 600 along its own axis. The bottom of the positioning post 800 is provided with a radially outwardly extending radial strip 810, and the bottom of the radial strip 810 is provided with a pressure block 811 that avoids the connecting post 110 and contacts the retaining ring 140. The peripheral wall of the positioning hole 130 is provided with a vertical opening 131 for the radial strip 810 to slide vertically. The top wall of the clearance recess 120 is provided with a vertical slot 121 that is circumferentially offset from the vertical opening 131. The upper and lower ends of the spring 700 contact the retaining ring 140 and the collar 310 respectively to push the area below the vertical slot 121. The radial strip 810 is embedded in the vertical slot 121; the vertical opening 131 is connected to the bottom of the vertical slot 121 through a rotation relief 122, and the radial strip 810 can rotate within the rotation relief 122. By engaging the radial strip 810 in the vertical slot 121, the radial strip 810 is circumferentially fixed, thereby fixing the height position of the positioning post 800, thus realizing the installation and fixation of the cover plate 600. The abutment ring 140 is used to transmit the force of the spring 700, so that the radial strip 810 is kept engaged in the vertical slot 121, ensuring a stable state. The pressure block 811 presses down on the abutment ring 140, while avoiding the connecting post 110, reducing structural interference.

[0058] Combination Figures 7 to 9 Describe how the radial strip 810 disengages from the vertical slot 121 and enters the vertical opening 131. For example... Figure 7As shown, at this time, the radial strip 810 is held in the position of being engaged in the vertical groove 121 by the abutment ring 140 and the spring 700. The spring 700 also applies a downward force to the collar 310, causing the locking block 320 to limit the protrusion 221, which remains engaged in the horizontal groove 112. Subsequently, the radial strip 810 can be pressed downwards, and the pressing block 811 presses down on the abutment ring 140 and compresses the spring 700 until the radial strip 810 disengages from the vertical groove 121, achieving... Figure 8 As shown, the radial bar 810 then rotates through the rotation clearance 122 and enters the position below the vertical opening 131. At this time, the radial bar 810 enters the vertical opening 131 upwards and disengages from the upper end of the vertical opening 131, thereby realizing the overall disassembly of the cover plate 600 and the positioning post 800. The above operation can be reversed to realize the installation of the cover plate 600 and the positioning post 800. The disassembly and assembly are simple and convenient, and the structure is stable during installation due to the continuous action of the spring 700.

[0059] Reference Figure 3 and Figure 13 In a further embodiment of the present invention, a downwardly extending surrounding plate 610 is provided around the cover plate 600. The surrounding plate 610 is provided with a clearance slot 620 for the radial strip 810 to rotate. The radial strip 810 extends out of the clearance slot 620 to facilitate operation of the radial strip 810 from the outside. One end of the clearance slot 620 is provided with a limiting end wall 621. When the radial strip 810 abuts against the limiting end wall 621, the radial strip 810 is aligned with the vertical opening 131, thereby facilitating accurate insertion of the radial strip 810 into the vertical opening 131 during installation. The clearance slot 620 allows the clearance slot 620 to extend out, facilitating manual operation of the rotating positioning post 800, thereby realizing installation or disassembly.

[0060] Reference Figure 13 and Figure 14 In a further embodiment of the present invention, the upper end of the positioning post 800 is provided with a locking head 820 whose contour is larger than that of the positioning post 800, and the lower part of the cover plate 600 is provided with a limiting protrusion 630 corresponding to the positioning post 800. The limiting protrusion 630 is provided with a locking groove 631 with a side opening. The locking head 820 is locked into the locking groove 631, thereby fixing the position of the positioning post 800 and the cover plate 600 in the vertical direction. This ensures that after the height position of the positioning post 800 is fixed, the height position of the cover plate 600 is also fixed. Specifically, the locking groove 631 is a semi-circular groove, and the bottom of the limiting protrusion 630 is provided with a semi-circular clearance opening 632. The diameter of the clearance opening 632 is smaller than that of the locking groove 631 and the locking head 820, thereby limiting the height of the locking head 820. The clearance opening 632 is used to allow the positioning post 800 to extend out of the locking groove 631. Furthermore, at least two of the side openings of the locking slots 631 are arranged opposite each other, thereby limiting the horizontal displacement of the cover plate 600 and fixing the cover plate 600 in the horizontal direction.

[0061] Reference Figure 12 and Figure 13 In a further embodiment of the present invention, the bottom of the cover plate 600 is provided with a downwardly protruding sealing ring 640, the outer periphery of which is adapted to and embedded in the receiving cavity. The sealing ring 640 is used to seal the receiving cavity, preventing the cover plate 600 from moving up or down and affecting the sealing of the receiving cavity.

[0062] It is understandable that, such as Figure 3 As shown, a flip-top cover 150 can be provided at the upper end of the receiving cavity. The edge of the top cover 150 has a wire passage 151 to allow the connecting wires of the solar panel 650 to extend into the receiving cavity below the top cover 150. The top cover 150 provides a certain degree of protection when the cover plate 600 is not installed.

[0063] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
