Description

Technical Field

[0001] This invention belongs to the field of displacement monitoring technology, specifically relating to a slope displacement monitoring device for road safety construction. Background Technology

[0002] Slope displacement monitoring equipment is mainly used to observe slope deformation in real time, providing crucial data support for engineering safety and geological disaster early warning. Based on monitoring principles and installation methods, these devices are mainly divided into three categories: surface displacement monitoring, deep displacement monitoring, and other auxiliary monitoring. Surface displacement monitoring equipment is one of the most common types. GNSS monitoring equipment is currently one of the most mainstream surface displacement monitoring technologies. By setting up a reference station in the stable area of ​​the slope and deploying monitoring stations in the deformed area, it uses satellite signals such as BeiDou and GPS for real-time dynamic differential positioning with millimeter-level accuracy. This type of equipment typically integrates low-power design, solar power supply, and 4G / 5G wireless communication modules, making it very suitable for unattended field environments. However, existing slope displacement monitoring equipment has the following problems: 1. During the use of existing slope displacement monitoring equipment, the GNSS positioning measurement station inside the equipment acts as a continuous heat source. During long-term, uninterrupted monitoring tasks, heat will continue to accumulate. In the continuous high temperature of summer, the internal temperature of the equipment is prone to rise continuously, which will lead to the deterioration of the performance of electronic components, signal drift, and poor positioning accuracy. Moreover, existing equipment mostly uses heat sinks for passive heat dissipation, which has poor heat dissipation effect.

[0003] 2. Existing slope displacement monitoring equipment typically has filters installed on the air inlet during use. These filters can become clogged over time, requiring disassembly and cleaning, which is time-consuming, labor-intensive, and inefficient. Summary of the Invention

[0010] Preferably, a fixing block is fixedly sleeved on both the left and right ends of the movable rod, and a cleaning brush is fixedly connected to the top of multiple fixing blocks. The top of the cleaning brush is in contact with the top of the filter screen.

[0011] Preferably, the mounting plate has rotatably mounted limit rollers at both its left and right ends, and the limit rollers are slidably connected inside the limit groove.

[0015] The beneficial effects of this invention are as follows: 1.

In summer, the heat exchange fluid is transported underground to cool it down, and the cooled heat exchange fluid then cools the GNSS positioning and measuring station. In winter, the heat exchange fluid absorbs heat from the ground and transfers the heat to the GNSS positioning and measuring station, achieving a two-way heat preservation mechanism that is "warm in winter and cool in summer." This active temperature regulation design is suitable for field working environments.

[0016] 2. Unlike existing technologies, this invention uses a heat exchange fan to draw cold air from the bottom and transfer it to the heat dissipation fins, thus removing heat from the GNSS positioning measurement station. This follows the principle of hot air rising, resulting in high heat convection efficiency. Furthermore, the heat exchange mechanism further enhances the heat dissipation efficiency.

[0017] 3. Unlike existing technologies, this invention simultaneously activates the self-cleaning mechanism when opening and closing the door. The self-cleaning mechanism scrapes and brushes the filter screen, effectively removing dust. Furthermore, as the self-cleaning mechanism is pulled to the front, the rotation of the self-cleaning scraper cleans the fixed scraper and cleaning brush, preventing the failure caused by excessive dust accumulation on the fixed scraper and cleaning brush during long-term use. This extends the service life of the fixed scraper and cleaning brush, eliminating the need for manual maintenance. Attached Figure Description

Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Example: Please refer to Figure 1 , Figure 2 and Figure 3 A slope displacement monitoring device for road safety construction includes a column 1, a base plate 10 installed at the bottom of the column 1, and a heat exchange mechanism 2 for heat dissipation inside the column 1. A maintenance mechanism 7 is installed on the rear side of the middle of the column 1. An electrical control box 3 is fixedly installed on the upper part of the column 1 by clamps. A self-cleaning mechanism 8 is installed inside the electrical control box 3. A GNSS mushroom antenna 4 is installed on the top of the column 1. The heat exchange mechanism 2 is filled with heat exchange fluid, which is a mixture of water and ethylene glycol, to achieve heat exchange between the heat exchange mechanism 2 and the ground, so as to achieve cooling and heat dissipation in summer and heat preservation and heating in winter. A fixed arm 5 is fixedly connected to the top of the column 1. A photovoltaic panel 6 is fixedly installed at the end of the fixed arm 5 away from the column 1. In use, the base plate 10 is used to fix the column 1 to the ground, the heat exchange mechanism 2 is used to exchange heat with the ground, the maintenance mechanism 7 is used to inspect and maintain the heat exchange mechanism 2, the electrical control box 3 is used to store and protect various components inside the device, and can achieve dustproof and waterproof. The column 1 is used to install the fixing arm 5, and the fixing arm 5 is used to provide a foundation for the installation and support of the photovoltaic panel 6. The self-cleaning mechanism 8 is used to clean the inside of the electrical control box 3.

[0022] Please see Figures 1-5 The electrical control box 3 includes a box body 31 that is detachably mounted on the column 1 via clamps. A box door 33 is hinged to the front side of the box body 31. Several exhaust holes 32 are evenly distributed on the lower top side of the box body 31. The exhaust holes 32 are connected to the interior of the box body 31. A temperature sensor 11 is fixedly installed on the bottom surface of the inner wall of the box body 31. The box body 31 is used to provide protection and a mounting base for its internal components. The exhaust holes 32 are used to exhaust air. The temperature sensor 11 is used to detect the temperature inside the box body 31. A hook is fixedly installed on the right side of the box body 31. During maintenance, the box door 33 is suspended on the hook by a rope (not shown in the figure) to avoid the problem of the box door 33 springing back during maintenance.

[0023] Please see Figure 3 and Figure 5The maintenance mechanism 7 includes a hinged door 71 hinged to the rear side of the middle part of the column 1. Several second fixing plates 74 are fixedly installed inside the column 1. A storage battery 73 is fixedly installed on the top of the second fixing plate 74. A fixing ring 75 is fixedly installed on the bottom of the second fixing plate 74. Several pressing plates 72 for pressing and fixing the storage battery 73 are fixedly installed on the inner wall of the hinged door 71. A sealing ring is provided at the connection between the hinged door 71 and the column 1 to achieve waterproofing of its internal structure.

[0024] In use, the second fixing plate 74 is used to support and install the battery 73. The hinged door 71 facilitates the inspection of its internal structure. The hinged door 71 is used to install the pressing plate 72, which is used to press and fix the battery 73. The battery 73 is electrically connected to the photovoltaic panel 6, storing the electrical energy generated by the photovoltaic panel 6 in the battery 73. The battery 73 is used to power the internal components of the equipment.

[0025] Please see Figure 2 , Figure 5 and Figure 6 The heat exchange mechanism 2 includes several heat exchange straight pipes 23 that are fixedly connected to a fixed ring 75. The outside of the heat exchange straight pipes 23 is attached to the outer wall of the battery 73. The top and bottom of the multiple heat exchange straight pipes 23 are fixedly connected to a manifold 24. The top manifold 24 is detachably and fixedly connected to a first connecting pipe 27. The top of the first connecting pipe 27 passes through the housing 31 and is fixedly connected to a heat exchange plate 26. A first fixing plate 25 is fixedly installed on the outside of the heat exchange plate 26. Several heat dissipation fins 22 are evenly installed on the rear side of the first fixing plate 25. A GNSS positioning measurement station 9 is installed on the front side of the heat dissipation fins 22 and the heat exchange plate 26. The GNSS positioning measurement station 9 has a built-in wireless communication module, data processing module, power interface and other structures. The GNSS positioning measurement station 9 is existing technology. The GNSS positioning measurement station 9 works in conjunction with the base station. The GNSS positioning measurement station 9 on the slope receives satellite signals and error correction data from the base station. After correction, high-precision real-time coordinates are obtained, thus realizing the monitoring of slope displacement. The bottom manifold 24 is detachably and fixedly connected to the second connecting pipe 28. The bottom of the second connecting pipe 28 is fixedly connected to the heat exchange coil 21. A circulation pump is installed on the second connecting pipe 28. The circulation pump is equipped with an anti-corrosion box (not shown in the figure) to prevent corrosion underground. The circulation pump is used to circulate the heat exchange fluid. One end of the heat exchange coil 21 is fixedly connected to the heat exchange plate 26 through the return pipe to realize the circulation of the heat exchange fluid. The heat exchange coil 21, the return pipe and the second connecting pipe 28 are all coated with an anti-corrosion coating.

[0026] In use, the heat exchange coil 21 is buried deep underground at the installation location. Since the underground temperature is lower than the surface temperature in summer and higher than the surface temperature in winter, in summer, the heat exchange fluid inside the heat exchange coil 21 conducts heat to the ground, thereby cooling the heat exchange fluid. The cooled heat exchange fluid then cools the heat exchange plate 26 and the GNSS positioning station 9, achieving cooling of the GNSS positioning station 9 in summer. In winter, the heat exchange fluid absorbs heat from the ground and transfers the heat to the GNSS positioning station 9, achieving insulation in winter. This realizes an active temperature regulation design, suitable for field working environments.

[0027] Please see Figure 4 , Figure 7 , Figure 8 , Figure 11 and Figure 12 The self-cleaning mechanism 8 includes an air intake component 81 located on the bottom right side of the housing 31. A drive component 82 is mounted on the air intake component 81. A cleaning component 84 is mounted on the drive component 82. A reciprocating component 85 is mounted on the cleaning component 84. A filter component 83 is mounted on the air intake component 81. The air intake component 81 includes a fixed sleeve 811 fixedly connected to the bottom of the housing 31. Limiting grooves 812 are provided on the inner walls of both the left and right sides of the fixed sleeve 811. A linear cam 813 is fixedly installed on the top right side of the inner wall of the fixed sleeve 811.

[0028] Please see Figure 7 , Figure 8 and Figure 11 The drive assembly 82 includes a pull rod 826 that extends through the front of the fixed sleeve 811. A hinge joint 824 is fixedly installed at the front end of the pull rod 826. A second connecting rod 823 is hinged to the front of the hinge joint 824. A first connecting rod 822 is hinged to the end of the second connecting rod 823 away from the hinge joint 824. A fixing head 821 is hinged to the end of the first connecting rod 822 away from the second connecting rod 823. The fixing head 821 is fixedly installed inside the door 33.

[0029] Please see Figure 7 , Figure 8 , Figure 9 and Figure 10 The filter assembly 83 includes a filter screen 831 fixedly installed on the top of the fixed sleeve 811. The bottom front side of the filter screen 831 has an installation groove 832. Several fixed shafts 833 are evenly rotatably installed inside the installation groove 832. Several self-cleaning scrapers 834 are fixedly installed on the outside of each fixed shaft 833. A gear 835 is fixedly installed at the rear end of the fixed shaft 833. A cooling fan is installed on the top of the filter screen 831. The cooling fan is electrically connected to the battery 73.

[0030] Please see Figure 11 , Figure 12 and Figure 13The cleaning component 84 includes a mounting plate 842 fixedly installed at the rear end of the pull rod 826. Several fixed scrapers 841 are evenly installed on the rear side of the mounting plate 842. The top of the fixed scrapers 841 is attached to the bottom of the filter screen 831. A first spring 825 is sleeved on the outside of the pull rod 826. The first spring 825 is fixedly installed between the inner wall of the mounting plate 842 and the fixed sleeve 811. Limiting rollers 814 are rotatably installed at both ends of the mounting plate 842. The limiting rollers 814 are slidably connected inside the limiting groove 812. An L-shaped rod 815 is fixedly installed on the left front end of the mounting plate 842. A rack 816 that cooperates with the gear 835 is fixedly installed on the top of the L-shaped rod 815.

[0031] Please see Figure 11 , Figure 12 and Figure 13 The reciprocating assembly 85 includes a third fixing plate 857 fixedly installed at the top center of the mounting plate 842. A movable rod 853 is movably passed through the center of the third fixing plate 857. A baffle 855 is fixedly installed at the middle of both ends of the movable rod 853. A second spring 856 is sleeved at both ends of the movable rod 853. The second spring 856 is fixedly installed between the baffle 855 and the third fixing plate 857. A first fixing block 854 is fixedly sleeved at both the left and right ends of the movable rod 853. A cleaning brush 851 is fixedly connected to the top of the first fixing block 854. The top of the cleaning brush 851 is in contact with the top of the filter screen 831. A fixing seat is fixedly installed at the right end of the movable rod 853. A rolling wheel 852 that is in contact with the linear cam 813 is rotatably installed on the fixing seat.

[0032] During operation, temperature sensor 11 detects the temperature inside the electrical control box 3. When the detected temperature exceeds the set threshold, the controller activates the cooling fan. The cooling fan draws outside air from the fixed sleeve 811. The air passes through the filter 831 and enters the electrical control box 3. The air then passes through the heat dissipation fins 22, carrying away heat from the heat dissipation fins 22, the first fixed plate 25, and the heat exchange plate 26. The heated air is then discharged from the exhaust port 32, achieving heat exchange and exhaust from bottom to top, which conforms to the principle of hot air rising. This enables rapid heat dissipation of the GNSS positioning measurement station 9. Combined with the heat exchange mechanism 2, this achieves rapid cooling of the GNSS positioning measurement station 9. Cooling is achieved when the temperature falls below a threshold, at which point the cooling fan automatically stops. When manual maintenance is performed on the inside of the electrical control box 3, opening the box door 33 causes it to rotate outwards, moving the fixed head 821 and its second connecting rod 823 forward. Simultaneously, this moves the mounting plate 842 and its pull rod 826 forward, and also moves the mounting plate 842 and its fixed scraper 841 forward. The fixed scraper 841 then performs a straight scraping motion on the bottom of the filter screen 831. As the mounting plate 842 moves forward, it simultaneously moves the third fixed plate 857 and its movable rod 853 forward, and also moves the fixed base and its rolling wheel 852 forward. During this forward movement, the rolling wheel 852... The rollers 852 and their movable rods 853 reciprocate left and right, respectively, by engaging with the protruding and recessed positions of the linear cam 813. This reciprocates the movement of the rollers 852 and their movable rods 853, simultaneously driving the first fixed block 854 and its cleaning brush 851 to reciprocate left and right, thus achieving the left and right reciprocating wiping of the filter screen 831. Combined with the scraping action of the fixed scraper 841, this cleans the filter screen 831, preventing dust from clogging it. When the mounting plate 842 moves forward, it simultaneously compresses the first spring 825. When the mounting plate 842 reaches the foremost position of the filter screen 831, the rack 816 gradually meshes with the gear 835, causing the gear 835 and its fixed shaft 833 to rotate. The rotation simultaneously drives the self-cleaning scraper 834 to rotate and scrape, realizing automatic cleaning of the fixed scraper 841 and cleaning brush 851. This avoids the problem of reduced cleaning effect caused by dust accumulation on the cleaning brush 851 and fixed scraper 841. The door 33 is opened to its maximum angle. At this time, the handle of the door 33 is hung on the hook with the hanging rope to fix the door 33 and prevent the door 33 from rebounding during maintenance. After maintenance is completed, the hanging rope is released. Under the restoring force of the first spring 825, the door 33 is moved backward. The fixed scraper 841 and cleaning brush 851 perform a second cleaning of the filter screen 831, improving the cleaning effect of the filter screen 831.

[0033] It should be noted that, in the use of this slope displacement monitoring equipment for road safety construction, the heat exchange coil 21 is buried underground at the installation location, and then the base plate 10 is fixed to the ground using bolts. At this time, the first connecting pipe 27 is connected to the heat exchange plate 26, and then the box 31 is installed onto the column 1 using clamps. The photovoltaic panel 6 and the fixing arm 5 are installed onto the column 1, and the photovoltaic panel 6 is electrically connected to the battery 73, thereby storing the electrical energy generated by the photovoltaic panel 6 into the battery 73. In summer, Temperature sensor 11 detects the temperature inside the electrical control box 3. When the detected temperature exceeds the set threshold, the heat exchange fluid inside the heat exchange coil 21 conducts heat to the ground. During the cooling process at the ground, the cooled heat exchange fluid is returned to the heat exchange plate 26 via a circulation pump. The heat exchange plate 26 has a hollow structure, facilitating the circulation of the heat exchange fluid. Subsequently, the low temperature is transferred to the GNSS positioning station 9, achieving cooling of the GNSS positioning station 9 in summer. At the same time, the controller starts the cooling fan, drawing outside air from the fixed sleeve 811. The air passes through the filter screen 831 and enters the electrical control box 3. The air passes through the heat dissipation fins 22, carrying away the heat from the heat dissipation fins 22, the first fixed plate 25, and the heat exchange plate 26. The heated air is then discharged from the exhaust port 32, achieving heat exchange and exhaust from bottom to top. In winter, when the temperature of the GNSS positioning station 9 is below the threshold, the circulation pump is started, circulating the heat from the ground to the heat exchange plate 26 via the heat exchange fluid, achieving cooling of the GNSS positioning station 9 in summer. The SS positioning measurement station 9 is designed for winter insulation, thus achieving an active temperature control design. When the inside of the electrical control box 3 is inspected and maintained, the box door 33 is opened. When the box door 33 is rotated outward, it drives the drive component 82 to move forward, simultaneously driving the cleaning component 84 and the reciprocating component 85 to move forward at the same time. The fixed scraper 841 is used to scrape the bottom of the filter screen 831 in a straight line, and the reciprocating component 85 scrapes the bottom of the filter screen 831 in a reciprocating straight line, thus achieving rapid cleaning of the filter screen 831 with good cleaning effect.

[0034] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
