Description

Technical Field

[0001] The present application relates to the technical field of displacement positioning monitoring equipment, and in particular to a GNSS displacement monitoring station. Background Art

[0002] GNSS displacement monitoring station is a device that uses the global satellite navigation system (GNSS) technology. It is mainly used for real-time monitoring of deformation, displacement, settlement and other parameters of large engineering structures such as buildings, bridges, and dams. This equipment, also known as a GNSS monitoring station or a GNSS displacement monitor, has the characteristics of high precision, high reliability, and high automation. The GNSS displacement monitoring station is mainly composed of a GNSS antenna, a solar panel, a main control chassis (with a main control transmission module) and a mounting bracket, including a base station and a measuring station. The device can upload data to the environmental monitoring platform through a 4G signal network. It is suitable for surface displacement monitoring and building deformation monitoring, such as landslides, slope displacements, bridge deformations, reservoir dams, and mining geological disasters.

[0003] In the related technology, a Chinese patent with application number CN202010721928.4 proposes a GNSS-based slope displacement monitoring device, including a monitoring column, a GNSS displacement detection device body and a protective component. The GNSS displacement detection device body is directly installed on the monitoring column, which is easy to install and can ensure monitoring accuracy; the displacement monitoring of the slope is realized by a combination of a monitoring column, a monitoring module, a GNSS receiver and a GNSS measurement antenna; the protective component includes a guardrail group, a rod group and a buffer component. Through the design of the guardrail group, the monitoring column can be well protected and its stability can be improved; the guardrail group is combined with the design of the buffer component, so that when the guardrail group is subjected to external force (soil or other objects will collide with the column when rolling on the slope), the external force can be consumed through the buffer component, thereby ensuring the structural stability of the entire guardrail group, realizing the protection of the monitoring column, so that the position of the monitoring column will not be displaced during the monitoring process, and the monitoring accuracy is ensured.

[0004] The above-mentioned related technologies have the following defects: when monitoring slope displacement, the GNSS displacement monitoring equipment needs to be set up outdoors in the mountains or on hillsides. Mountains and other terrain features may block or attenuate the signal transmission of the GNSS displacement monitoring equipment, affecting the accuracy of the monitoring data and the timeliness of the data feedback; at the same time, the GNSS displacement monitoring equipment is mainly powered by solar panels and batteries. Once the signal transmission quality is reduced, it is necessary to increase the signal receiving and transmitting power, resulting in reduced battery life, especially in severe weather such as storms and hail. The tilted solar panels have large wind resistance and are prone to damage, which further seriously affects the battery life, so that the GNSS displacement monitoring equipment is difficult to operate independently outdoors for a long time and requires regular maintenance, which greatly increases the monitoring cost. Summary of the invention

[0049] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0050] The present application embodiment discloses a GNSS displacement monitoring station. Figure 1 , Figure 2 and Figure 3 It includes a column 1, a GNSS displacement monitoring device body 11, a solar panel 12, and a battery. The upper end of the solar panel 12 is hinged on the column 1 and is inclined. The solar panel 12 converts solar energy into electrical energy and stores it in the battery. The battery supplies power to the GNSS displacement monitoring device body 11 and other required components.

[0051] The column 1 is provided with:

[0052] The folding connecting rod 2 is formed by hingedly connecting two connecting rods, one end of which is hingedly connected to the bottom end of the solar panel 12, and the other end is hingedly connected to the column 1, and a hinge joint 21 is provided on the folding connecting rod 2, and the folding connecting rod 2 realizes its own flipping and folding through the hinge joint 21;

[0053] The mounting tube 31 is fixed to the top of the column 1 and arranged along the length direction of the column 1;

[0054] The signal gain net 4 is installed on the outer peripheral side of the installation tube 31 and is electrically connected to the signal transceiver antenna of the GNSS displacement monitoring device body 11. The signal gain net 4 is made of metal and has a certain elasticity, and can be partially changed in shape without destroying its structure;

[0055] The control rod 32 is slidably disposed in the mounting tube 31;

[0056] A plurality of control ropes 33 are provided, and one end of the control ropes 33 is fixedly connected to the control rod 32, and the other end is fixedly connected to the outer periphery of the signal gain net 4; in the initial state, the top of the control rod 32 protrudes from the top of the mounting tube 31, and the signal gain net 4 is bent upward and surrounded by the plurality of control ropes 33;

[0057] A control mechanism, used to drive the control rod 32 downward to retract the signal gain net 4 in extreme weather;

[0058] The joint control assembly is used to drive the hinged joint 21 to move upward when the control rod 32 moves downward so as to fold the folding link 2.

[0059] After such arrangement, when the GNSS displacement monitoring device body 11 is working, the signal gain net 4 is bent upward and surrounded in an inverted umbrella shape under the pulling action of multiple control ropes 33. Since the signal gain net 4 is made of metal and is electrically connected to the signal transceiver antenna of the GNSS displacement monitoring device body 11, the inverted umbrella-shaped signal gain net 4 can constitute a reflector dish of the parabolic antenna and enter a gain state; by focusing and reflecting signals, it helps to improve the signal strength received by the antenna of the GNSS displacement monitoring device body 11, thereby significantly improving the accuracy of the satellite positioning of the GNSS displacement monitoring device body 11 and improving the accuracy of the monitoring data.

[0060] In extreme weather, the control mechanism can control the control rod 32 to move downward, and with the help of multiple control ropes 33 to pull the signal gain net 4, the signal gain net 4 is folded downward and enters a protective state, thereby reducing the wind resistance of the signal gain net 4 as much as possible to avoid damage; at the same time, the signal gain net 4 covering the top of the column 1 can also protect the GNSS displacement monitoring device body 11, so as to prevent hail, heavy rain or foreign objects falling with the wind from directly impacting the exposed parts of the GNSS displacement monitoring device body 11, causing damage to the GNSS displacement monitoring device body 11. And when the control mechanism drives the control rod 32 to move downward, the joint control component also drives the folding connecting rod 2 to fold, so that the solar panel 12 is transformed from an inclined state to a nearly vertical state, which can also reduce the wind resistance and vertical contact area of ​​the solar panel 12, thereby reducing the probability of the solar panel 12 being blown off by strong wind or hit by hail, and reducing the probability of the solar panel 12 being damaged in extreme weather, which can ensure the long-term stable operation of the monitoring equipment of the present application, thereby reducing economic losses.

[0061] Specifically, refer to Figure 1 and Figure 2 , the signal gain network 4 includes:

[0062] The elastic metal ribs 41 are provided in plurality and are distributed in a circumferential array with equal spacing around the axis of the mounting tube 31. One end of the elastic metal ribs 41 is fixed to the outer peripheral wall of the mounting tube 31, and the other end extends radially outward along the mounting tube 31. The elastic metal ribs 41 bend downward when no external force is applied, and the elastic metal ribs 41 are made of spring steel and have certain rigidity and elastic deformation capacity.

[0063] The shaping wire 42 is provided in multiple and concentric circles. The shaping wire 42 is sequentially connected to multiple elastic metal ribs 41 and is arranged coaxially with the mounting tube 31. The elastic metal ribs 41 and the shaping wire 42 are electrically connected to the signal transceiver antenna of the GNSS displacement monitoring device body 11. Specifically, the shaping wire 42 is set as a twisted steel wire, which has good tensile strength, can significantly improve the structural strength of the signal gain net 4, and improve the protection capability of the signal gain net 4;

[0064] One end of the control rope 33 away from the control rod 32 is fixed to the free end of the elastic metal rib 41 . The length of the control rope 33 is shorter than that of the elastic metal rib 41 , and the control rope 33 is an elastic rope.

[0065] After such arrangement, a plurality of radial elastic metal ribs 41 can play the role of the main keel supporting the main body of the signal gain net 4, and the free ends thereof can be deformed and folded upward or downward, so that the main body of the signal gain net 4 is in an upwardly surrounding shape or a downwardly surrounding shape, which is convenient for the shape change of the signal gain net 4 and always maintains good structural strength and shaping effect; a plurality of shaping metal wires 42 are distributed in a concentric circle shape on the elastic metal ribs 41, and a plurality of elastic metal ribs 41 can be connected in series, and the connection stability between adjacent elastic metal ribs 41 is improved, and the deformation consistency of the plurality of adjacent elastic metal ribs 41 is also improved, ensuring that the signal gain net 4 can be in a complete umbrella shape when flipped upward or flipped downward to ensure enhanced signal and protection effects.

[0066] During specific operation, after the control rod 32 is lifted up in the installation tube 31, it pulls the free end of the elastic metal rib 41 upward through multiple control ropes 33, so that the elastic metal rib 41 bends upward, and the signal gain net 4 is in a gain state of bending upward and surrounding; and when the control rod 32 is moved down in the installation tube 31, the upward flipping force of the control rope 33 on the elastic metal rib 41 is cancelled, and the elastic metal rib 41 follows the downward movement of the control rod 32 driven by its own shape restoring force to flip and surround downward, so that after the control rod 32 is moved down, the signal gain net 4 can automatically follow and flip to a downward surrounding protective state, so as to provide a protective effect for the GNSS displacement monitoring equipment body 11 on the top of the column 1.

[0067] In addition, refer to Figure 1 , Figure 2 and Figure 3 Folding links 2 are provided on both sides of the bottom end of the solar panel 12, a cross bar 22 is connected between the two hinge joints 21, and torsion springs 23 are provided at both ends of the cross bar 22. The two ends of the torsion spring 23 are respectively pressed against the two rod parts of the folding link 2; when the folding link 2 is in a folded state, the torsion spring 23 is twisted and torsional deformed, and at this time the solar panel 12 is flipped from an inclined state to a nearly vertical state.

[0068] And, refer to Figure 1 and Figure 4 , the above-mentioned joint control components include:

[0069] The movable pulley 51 is installed on the cross bar 22, specifically, installed in the middle of the cross bar 22 to maintain the stability of the cross bar 22;

[0070] A fixed pulley 52 is installed on the top of the column 1 or the solar panel 12; and

[0071] One end of the traction rope 53 is fixed to the bottom of the axle of the fixed pulley 52, and the other end is wrapped around the movable pulley 51 from the bottom, and then wrapped around the movable pulley 51 from the top and connected to the bottom of the control rod 32; when the control rod 32 moves downward, the traction rope 53 is pulled and the movable pulley 51 drives the cross bar 22 to move upward, so as to fold the folding connecting rod 2.

[0072] The above control mechanisms include:

[0073] A weather monitoring module is used to detect extreme weather such as strong winds, heavy rains, and hail. The weather monitoring module is a combination of one or more of an anemometer, a rain gauge, a pressure sensor, and an air pressure sensor;

[0074] The driving rack 61 is fixed to the control rod 32 and arranged along the length direction of the control rod 32;

[0075] The driving gear 62 is rotatably mounted in the column 1 and meshedly connected with the driving rack 61;

[0076] A driving motor 63 is installed in the column 1 and is used to drive the driving gear 62 to rotate; and

[0077] The controller is connected to the drive motor 63 and the meteorological monitoring module, and is configured to control the drive motor 63 to drive the drive gear 62 to rotate forward when the meteorological monitoring module detects extreme weather so that the control rod 32 moves down to a set position, such as the connection between the top of the control rod 32 and the control rope 33 is close to the top of the mounting tube 31; and when the meteorological monitoring module detects that the weather returns to normal, such as the wind force drops below a preset value, the rainfall drops below a preset value, or there is no foreign object impacting the pressure sensor on the column 1, the controller controls the drive motor 63 to drive the drive gear 62 to reverse so that the control rod 32 moves up to the initial position.

[0078] Therefore, when the meteorological monitoring module detects abnormal weather, the controller controls the drive motor 63 to work so that the drive motor 63 drives the drive gear 62 to rotate forward. When the drive gear 62 rotates, it drives the drive rack 61 meshing with it to move downward, thereby pushing the control rod 32 to move downward. When the control rod 32 moves downward, the elastic metal rib 41 is lowered by external constraints and returns to a state of being fully gathered downward. At this time, the signal gain network 4 enters a protective state. At the same time, when the control rod 32 moves downward, the control rod 32 drives the free end of the traction rope 53 to move downward, and the traction rope 53 pulls the movable pulley 51 upward under the action of the labor-saving pulley group composed of the movable pulley 51 and the fixed pulley 52, that is, pulls the cross bar 22 upward. At this time, the cross bar 22 moves upward and overcomes the torsional deformation force of the torsion spring 23, so that the folding link 2 enters the folded state, and the solar panel 12 flips on the column 1 from the inclined state to the nearly vertical state; wherein, the setting of the movable pulley 51 can not only play the labor-saving control of the folding link 2 when the folding link 2 is stored and folded by the traction rope 53, but also the movable pulley 51 can follow the position of the cross bar 22 for follow-up adjustment, so that no matter what posture the solar panel 12 is flipped to, the traction rope 53 can effectively achieve the storage driving effect of the folding link 2.

[0079] When the weather monitoring module detects that the weather returns to normal, the controller controls the drive motor 63 to work, so that the drive motor 63 drives the drive gear 62 to reverse, and the drive gear 62 drives the meshing drive rack 61 to move upward when rotating, thereby pushing the control rod 32 to move upward, and the control rod 32 moves upward, so that the signal gain network 4 enters the gain state. At the same time, when the control rod 32 moves upward, the pulling effect of the traction rope 53 on the movable pulley 51 and the cross bar 22 gradually weakens, and the folding link 2 is driven to flip in the opposite direction to the unfolded state under the torsion deformation force of the torsion spring 23 at both ends of the cross bar 22, and the movable pulley 51 moves downward, and the solar panel 12 flips to its lower end away from the column 1 and enters the tilted state, thereby realizing the synchronous adjustment of the solar panel 12 and the signal gain network 4, without the need to set up multiple sets of power mechanisms, and is easy to maintain and less affected by external interference.

[0080] Furthermore, considering that the labor-saving pulley group composed of the movable pulley 51 and the fixed pulley 52 saves pulling force, but increases the pulling stroke, that is, the traveling distance of the pulling rope is much greater than the traveling distance of the movable pulley 51, specifically nearly twice, in order to ensure that the pulling rope can fully pull the fixed pulley 52 up to the required distance while following the downward movement of the control rod 32, that is, to ensure that after the control rod 32 moves down into place, the folding connecting rod 2 can also be folded into place, and the solar panel 12 is flipped and stored into place.

[0081] Reference Figure 4A winding roller 71 for winding up the end of the traction rope 53 close to the control rod 32 is rotatably installed in the column 1. An opening for the traction rope 53 to pass through is penetrated by the side wall of the column 1. A winding gear 72 is coaxially fixedly connected to one end of the winding roller 71. A transmission gear (not shown in the figure) meshing with the control rack is rotatably installed in the column 1. An acceleration gear 73 meshing with the winding gear 72 is coaxially fixedly connected to the transmission gear. The number of teeth of the acceleration gear 73 is greater than that of the winding gear 72, and the number of teeth of the corresponding family gear is also greater than that of the transmission gear.

[0082] When the control rod 32 moves downward, it drives the control rack to move downward, and the transmission gear rotates first. When the transmission gear rotates, it drives the acceleration gear 73 with a large number of teeth coaxial with it to rotate. When the acceleration gear 73 rotates, it drives the winding gear 72 with a small number of teeth coaxial with it to rotate. When the winding gear 72 rotates, it drives the winding roller 71 to wind up the traction rope, thereby realizing the long-distance movement of the traction rope 53 when the control rod 32 moves a small distance.

[0083] The implementation principle of a GNSS displacement monitoring station in the embodiment of the present application is:

[0084] When the GNSS displacement monitoring device body 11 is working, the signal gain net 4 is bent upward under the pulling action of multiple control ropes 33 to form an inverted umbrella shape. Since the signal gain net 4 is made of metal and is electrically connected to the signal transceiver antenna of the GNSS displacement monitoring device body 11, the inverted umbrella-shaped signal gain net 4 can constitute a reflector dish of the parabolic antenna and enter a gain state; by focusing and reflecting signals, it helps to improve the signal strength received by the antenna of the GNSS displacement monitoring device body 11, thereby significantly improving the accuracy of the satellite positioning of the GNSS displacement monitoring device body 11 and improving the accuracy of the monitoring data and the monitoring quality.

[0085] When extreme weather occurs, it is detected by the meteorological monitoring module, and the controller controls the drive motor 63 to work and drive the control rod 32 to move downward. The upward flipping force of the control rope 33 on the elastic metal rib 41 is cancelled, and the elastic metal rib 41 follows the downward movement of the control rod 32 and flips downward and surrounds under the drive of its own shape recovery force, so that after the control rod 32 moves downward, the signal gain net 4 can automatically follow and flip to a downward surrounding state to be in a protective state, thereby reducing the wind resistance of the signal gain net 4 itself as much as possible to avoid the possibility of damage; at the same time, the signal gain net 4 covering the top of the column 1 downward can also protect the GNSS displacement monitoring device body 11 to prevent hail, heavy rain or foreign objects falling with the wind from directly impacting the exposed part of the GNSS displacement monitoring device body 11, causing damage to the GNSS displacement monitoring device body 11, thereby ensuring the long-term and stable operation of the monitoring equipment of the present application.

[0086] When the control mechanism drives the control rod 32 to move downward, the traction rope 53 follows the control rod 32 to move downward and pulls the movable pulley 51 upward, and then the cross bar 22 moves upward to fold the folding link 2, so that the solar panel 12 is transformed from an inclined state to a nearly vertical state, and the wind resistance and vertical contact area of ​​the solar panel 12 can also be reduced, thereby reducing the probability of the solar panel 12 being blown off by strong winds or hit by hail, and reducing the probability of the solar panel 12 being damaged in extreme weather, thereby reducing economic losses.
