Description

Technical Field

[0001] This utility model relates to the field of deformation monitoring technology, and more specifically, to a deformation monitoring system that integrates GNSS and wire displacement gauge. Background Technology

[0002] Satellite navigation and positioning technology has largely replaced ground-based radio navigation, traditional geodetic surveying, and astronomical surveying navigation and positioning technologies, driving new developments in the fields of geodesy and navigation. Today, GNSS systems are not only fundamental infrastructure for national security and the economy, but also important indicators of a modern great power's status and comprehensive national strength. Due to their significant political, economic, and military implications, major military powers and economies worldwide are vying to develop independent satellite navigation systems. Deformation monitoring devices can monitor the deformation of slopes, dams, and other structures in real time, and are commonly used in geological disaster prevention, geodesy, and engineering construction. Because BeiDou satellite positioning antennas operate continuously, using BeiDou satellite positioning technology ensures real-time monitoring.

[0003] Currently, deformation monitoring devices have the following drawbacks during use: 1. When installing the device, in order to maintain its levelness, a cement block needs to be built on the ground before the device is installed on the cement block. This not only wastes time and manpower but also cement materials; 2. The signal receiver in the monitoring device is exposed at the top of the equipment for a long time. When the equipment needs to be moved or is temporarily not used due to bad weather, the exposed signal receiver is prone to damage. Utility Model Content

[0004] The purpose of this invention is to address the problems of existing deformation monitoring devices, such as the need to build cement blocks for installation, which is time-consuming and labor-intensive, and the fact that the exposed signal receivers are easily damaged when the device is moved or not in use.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0006] A deformation monitoring system integrating GNSS and wire displacement gauges includes a base, a movable column mounted on top of the base, and a signal receiver mounted on top of the movable column, and further includes:

[0007] The adjustment mechanism includes fixed seats disposed on the four sides of the base, a propulsion assembly disposed on the top of the fixed seats, and a pressing rod movably disposed between the propulsion assembly and the movable column;

[0008] A storage component is provided, which is located on the top of the movable column, and the signal receiver is located inside the storage component. The storage component is used to store and protect the signal receiver.

[0009] As a preferred technical solution of this application, the movable column includes a fixed column disposed on the top of the base and an adjusting column movably disposed on the top of the fixed column. The top of the fixed column is provided with a storage sleeve, and the bottom of the adjusting column is provided with a first ball bearing. The lower half of the first ball bearing is rotatably connected inside the storage sleeve.

[0010] As a preferred technical solution of this application, the fixed seat is provided with a moving groove inside, and the propulsion assembly includes a lead screw rotatably disposed on the side wall of the fixed seat and extending into the moving groove, and a moving seat slidably disposed in the moving groove and threadedly connected to the lead screw. One end of the extrusion rod is movably connected to the adjusting column, and the other end of the extrusion rod is movably connected to the top of the moving seat through a third ball bearing.

[0011] As a preferred technical solution of this application, four equidistantly distributed second balls are movably connected to the side wall of the adjusting column. The end of the second ball away from the adjusting column is mounted with a U-shaped frame through a connecting rod. The end of the pressing rod away from the moving seat is rotatably connected to the U-shaped frame.

[0012] As a preferred technical solution of this application, the fixed base has limit grooves on both side walls, and a number of limit plates are slidably connected inside the limit grooves, and positioning stakes are slidably connected to the surface of the limit plates.

[0013] As a preferred technical solution of this application, the storage component includes a storage box disposed on the top of the adjustment column, a support cylinder disposed on the bottom wall of the storage box, a slide rod slidably disposed inside the support cylinder, a first spring disposed between the bottom of the slide rod and the bottom wall of the support cylinder, and a mounting plate disposed on the top of the slide rod. The signal receiver is disposed on the top of the mounting plate, and the top of the storage box has a storage opening for the signal receiver to pass through.

[0014] As a preferred technical solution of this application, the storage box is provided with a fixing frame on both side walls, and a sealing plate extending into the storage box is slidably connected inside the fixing frame. A second spring is connected between the sealing plate and the bottom wall of the fixing frame.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. When installing the monitoring device, first fix the base and the fixed seat on the ground. When the monitoring device on the top of the movable column tilts, the set adjustment components can drive the squeezing rod to move horizontally on the fixed seat through the pushing mechanism. At this time, the top of the squeezing rod will squeeze the movable column, causing the movable column to deflect relative to the base. Therefore, through the adjustment components on the four sides of the base, the movable column can be squeezed to rotate in all directions, so as to push the movable column to make the monitoring device on top of it horizontal as needed. This solves the problem of the existing technology that requires stacking cement blocks before installing the monitoring device, which not only wastes time and manpower, but also wastes cement materials.

[0017] 2. With the storage components in place, when the monitoring device is installed and ready for use, the sealing plate in the storage box opening is slid inwards towards the fixed frame to open the storage box. At this time, the fixed cylinder, the first spring, the slide rod, and the mounting plate will automatically eject the signal receiver from the storage box for use. When the device needs to be moved or temporarily stopped due to severe weather, the signal receiver can be pressed down to squeeze it into the storage box. At this time, the second spring will eject the sealing plate from the fixed frame to block the storage opening again, thus protecting the signal receiver. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0027] like Figure 1 and Figure 2 As shown, this embodiment proposes a deformation monitoring system integrating GNSS and a wire displacement meter, including a base (1), a movable column set on the top of the base (1), and a signal receiver (2) set on the top of the movable column. It also includes an adjustment mechanism and a storage component. The adjustment mechanism is set between the base 1 and the movable column and is used to adjust the angle of the signal receiver on the top of the movable column. The storage component is set on the top of the movable column, and the signal receiver (2) is set inside the storage component. The storage component is used to store and protect the signal receiver (2).

[0028] When installing the monitoring device, the base 1 and the fixing seat 5 are first fixed on the ground. The signal receiver 2 can receive and process the deformation monitoring data of the fused GNSS and the wire displacement meter, which is convenient for monitoring and processing different locations. When the monitoring device on the top of the movable column tilts, the angle of the signal receiver on the top of the movable column can be leveled by the setting adjustment component. Therefore, it is not necessary to first pile up cement blocks on the ground before installing the device, which not only saves time and manpower, but also saves cement resources. Moreover, when the device is moved or the device is suspended due to bad weather, the setting storage component can also store and protect the signal receiver 2, thereby preventing the signal receiver 2 from being damaged by long-term exposure.

[0029] like Figures 1 to 5 As shown, in a preferred embodiment, based on the above method, the adjustment mechanism further includes fixed seats 5 disposed on the four sides of the base 1, a push assembly disposed on the top of the fixed seats 5, and a pressing rod 6 movably disposed between the push assembly and the movable column.

[0030] The movable column includes a fixed column 3 set on the top of the base 1 and an adjustable column 4 movably set on the top of the fixed column 3. The fixed column 3 is provided with a storage sleeve 301 on the top, and the adjustable column 4 is provided with a first ball bearing 401 at the bottom. The lower half of the first ball bearing 401 is rotatably connected inside the storage sleeve 301.

[0031] The fixed seat 5 has a moving groove 501 inside. The pushing assembly includes a lead screw 7 rotatably disposed on the side wall of the fixed seat 5 and extending into the moving groove 501, and a moving seat 8 slidably disposed in the moving groove 501 and threadedly connected to the lead screw 7. One end of the pressing rod 6 is movably connected to the adjusting column 4, and the other end of the pressing rod 6 is movably connected to the top of the moving seat 8 through the third ball 801.

[0032] The side wall of the adjusting column 4 is movably connected to four equally spaced second balls 402. The end of the second balls 402 away from the adjusting column 4 is mounted with a U-shaped frame 10 through a connecting rod 403. The end of the pressing rod 6 away from the moving seat 8 is rotatably connected to the U-shaped frame 10.

[0033] When the signal receiver 2 on the adjusting column 4 and the distribution box are tilted, a screw 7 can be rotated to move the movable seat 8 on the fixed seat 5 on one side of the base 1. At this time, the movable seat 8 will drive the pressing rod 6 to move the adjusting column 4 to push it, so that the adjusting column 4 tilts relative to the fixed column 3. Therefore, by rotating the screws 7 on the four sides of the base 1, the adjusting column 4 can be driven to deflect in all directions, so that the monitoring device on the top of the adjusting column 4 can be pushed to a horizontal position as needed. Compared with the existing technology of first piling up cement blocks on the ground and then installing the device, this application can save the speed and manpower of horizontal adjustment of the monitoring device, and also save cement materials.

[0034] The fixed base 5 has limit grooves 502 on both sides of its fixed base 5. Several limit plates 9 are slidably connected inside the limit grooves 502. Positioning stakes 901 are slidably connected to the surface of the limit plates 9. By sliding the limit plates 9, each limit plate 9 can be moved to a suitable position as needed, and then the positioning stakes 901 can be driven into the soil, which makes it easier to fix the base 1 more stably.

[0035] like Figure 2 and Figure 6 As shown, in a preferred embodiment, based on the above method, the storage assembly further includes a storage box 11 disposed on the top of the adjustment column 4, a support cylinder 12 disposed on the inner bottom wall of the storage box 11, a slide rod 1201 slidably disposed inside the support cylinder 12, a first spring 1202 disposed between the bottom of the slide rod 1201 and the inner bottom wall of the support cylinder 12, and a mounting plate 13 disposed on the top of the slide rod 1201. The signal receiver 2 is disposed on the top of the mounting plate 13, and the top of the storage box 11 has a storage opening for the signal receiver 2 to pass through.

[0036] The storage box 11 has a fixed frame 14 on both sides. A sealing plate 1401 extending into the storage box 11 is slidably connected inside the fixed frame 14. A second spring 1402 is connected between the sealing plate 1401 and the bottom wall of the fixed frame 14.

[0037] When the device needs to be moved or temporarily stops working due to inclement weather, the signal receiver 2 can be pressed down to press it into the storage box 11. At this time, the downward movement of the signal receiver 2 will cause the slide rod 1201 to slide into the support cylinder 12 and compress the first spring 1202. At this time, the second spring 1402 will be released, causing the sealing plate 1401 to pop out of the fixing frame 14 and block the storage opening of the storage box 11, thus protecting the signal receiver 2. When the monitoring device needs to be used again, the sealing plate 1401 can be pushed to both sides of the storage box 11 to push the sealing plate 1401 into the fixing frame 14 and open the storage opening. At this time, the first spring 1202 will be released, causing the slide rod 1201 to spring up and reset, thus allowing the signal receiver 2 to be moved out of the storage box 11 for use.

[0038] The working principle of this utility model is as follows: When installing the monitoring device, the base 1 and the fixed seat 5 are first fixed on the ground. The signal receiver 2 can receive and process the deformation monitoring data from the fused GNSS and the line displacement gauge, facilitating monitoring of different locations. When the signal receiver 2 and the distribution box on the top of the movable column tilt, a screw 7 can be rotated to move the movable seat 8 on the fixed seat 5 on one side of the base 1. At this time, the movable seat 8 will drive the pressing rod 6 to move the adjusting column 4, causing the adjusting column 4 to tilt relative to the fixed column 3. Therefore, by rotating the screws 7 on all four sides of the base 1, the adjusting column 4 can be deflected in various directions, thereby pushing the monitoring device on the top of the adjusting column 4 to a horizontal position as needed. Compared with the existing technology of first piling up cement blocks on the ground before installing the device, this application can save costs. The system reduces the speed and manpower required for horizontal adjustment of the monitoring device and also saves cement materials. Furthermore, when the device needs to be moved or temporarily shut down due to inclement weather, the signal receiver 2 can be pressed down into the storage box 11. This downward movement of the signal receiver 2 causes the sliding rod 1201 to slide into the support cylinder 12, compressing the first spring 1202. The release of force on the second spring 1402 causes the sealing plate 1401 to pop out of the fixing frame 14, blocking the storage opening of the storage box 11, thus protecting the signal receiver 2. When the monitoring device needs to be used again, the sealing plate 1401 is moved to both sides of the storage box 11, pushing it into the fixing frame 14 to open the storage opening. The release of force on the first spring 1202 causes the sliding rod 1201 to spring upward and reset, allowing the signal receiver 2 to be removed from the storage box 11 for use.

[0039] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
