Description

Technical Field

[0001] This utility model relates to the field of GNSS displacement monitoring stations, specifically to a GNSS displacement monitoring device for reservoir dam displacement. Background Art

[0002] The GNSS displacement monitoring station mainly consists of a GNSS antenna, solar panels, a main control chassis (containing a main control transmission module), and mounting brackets. It is divided into a base station and a measuring station, and features high accuracy, low power consumption, high cost-effectiveness, and portable installation. The equipment can upload data to the environmental monitoring platform via 4G and Ethernet, and is powered by solar energy, making installation unrestricted by geographical location or terrain. It is suitable for monitoring surface displacement and building deformation, such as landslides, slope displacement, bridge deformation, reservoir dams, and mining geological hazards.

[0003] GNSS stands for Global Navigation Satellite System. It is a space-based radio navigation and positioning system that provides users with all-weather 3D coordinates, velocity, and time information from any location on the Earth's surface or in near-Earth space. It is a general term for all satellite navigation systems, including global, regional, and augmented systems.

[0004] The base station is installed in a stable location where its position will not change. The measuring station is installed in a location where displacement may occur, i.e., where displacement deformation needs to be measured. The equipment must be installed in an open area, without obstructing the antenna; otherwise, it will affect the reception of satellite signals, leading to positioning failure.

[0005] The main control unit of the existing GNSS displacement monitoring station is fixed on the bracket. However, the main control unit needs to be maintained and inspected regularly. When the operator maintains and inspects the main control unit, he / she needs to climb to a height to operate, which is troublesome and inefficient.

[0006] Meanwhile, during long-term use of reservoir dam displacement monitoring, rainwater can easily enter the main control cabinet, potentially damaging the main control transmission module inside. Utility Model Content

[0007] One objective of this invention is to provide a GNSS displacement monitoring station for reservoir dam displacement monitoring. The support plate and control box can be moved up and down on the bracket by means of a telescopic component, which makes it easier for operators to maintain the components in the control box and makes it easier to operate and use.

[0008] This objective is achieved using the following technical solution:

[0009] The GNSS displacement monitoring station for reservoir dam displacement monitoring includes a support frame, on which solar panels, an antenna, and a control cabinet are mounted. The support frame consists of an upper and a lower frame, with the lower end of the lower frame connected to the ground. A connecting ring is fitted onto the support frame, allowing it to slide up and down. The side of the connecting ring connects to a support plate, and the control cabinet is connected to the support plate. A telescopic assembly is mounted on the lower frame and connected to the support plate.

[0010] The telescopic assembly moves the support plate and control box up and down. During normal use, the support plate and control box are located on the upper bracket. When maintenance is required, the support plate and control box are located on the lower bracket, which facilitates quick maintenance by operators.

[0011] Because the components in the control chassis are connected to data cables, which are housed within the bracket, the data cables might detach from the control chassis when it moves up and down, affecting the normal operation of the structure. Therefore, the upper and lower brackets are equipped with connecting slide grooves, each with a sliding component that can move up and down within the groove. The sliding component connects to a support plate, with one end of the data cable passing through the sliding component and connecting to a module inside the control chassis. The other end of the data cable is located within the bracket. When the support plate moves up and down, it moves the sliding component along with it, preventing the connection between the control chassis and the data cable from being pulled during movement. More preferably, the sliding component is equipped with a retaining clip to hold the data cable, further preventing the connection between the control chassis and the data cable from being pulled and detached.

[0012] Meanwhile, a shielding box is installed on the lower support. The upper end of the shielding box is open and opposite to the support plate, while the lower end of the shielding box is in contact with the ground. When it rains, the telescopic component keeps the control box inside, further protecting it from prolonged contact with rainwater, which could damage the control box. Rainwater entering the control box could affect the internal components and thus the use of the device.

[0013] The shielding box has an opening on its side, and a shielding door is installed on the opening. When the control box is located inside the shielding box and the operator needs to perform maintenance on the control box, the maintenance operation can be carried out by opening the shielding door.

[0014] Secondly, a sensor baffle is installed on the top of the shielding box, and a sensor component is installed on the sensor baffle. When the support plate and control box are on the sensor baffle and need to enter the shielding box, the sensor component controls the sensor baffle to shorten, allowing the support plate and control box to enter the shielding box through the sensor baffle. After the support plate and control box are in the shielding box, the sensor component controls the sensor baffle to extend, and the sensor baffle blocks the opening on the top of the shielding box, so that the shielding box can better protect the control box.

[0015] Preferably, a drain pipe is provided at the lower end of the shield box. When rainwater enters the shield box during the opening of the sensor baffle, the rainwater can be quickly drained through the drain pipe, preventing rainwater from remaining in the shield box.

[0016] In the above structure, the telescopic component can be of various types, such as an electrically operated or manually operated telescopic rod. The key is to enable the support plate and control housing to move up and down. Specifically, the telescopic component is a telescopic rod, with its lower end connected to the inner bottom of the shielding box and its upper end connected to the support plate.

[0017] To further improve the telescopic efficiency and ensure stable movement of the control chassis, the inventors have preferred a telescopic assembly, which includes a first gear and a second gear connected to a support plate, and a third gear connected to a lower bracket.

[0018] The first gear component is a horizontally positioned gear rod, and the second gear component is a disc-shaped gear disk.

[0019] The third gear component is a vertically arranged gear rod. The third gear component is connected to the lower support through an annular groove. The third gear component rotates along the annular groove on the lower support with the center line of the support as the axis.

[0020] The first gear is located above and tangent to the second gear, and the third gear is located to the side of the second gear and is tangent to it. The first gear meshes with the second gear, and the third gear meshes with the second gear.

[0021] When the first gear rotates circumferentially, it acts on the second gear, causing the second gear to rotate circumferentially. During the rotation of the second gear, it acts on the third gear, causing the second gear to move up and down along the straight line where the third gear is located.

[0022] Preferably, the second gear component is provided with a connecting hoop, which is detachably connected to the lower bracket. When the connecting hoop is connected to the lower bracket, the second gear component is fixed on the lower bracket and cannot move up or down or rotate. When the connecting hoop is separated from the lower bracket, the connecting hoop rotates circumferentially on the lower bracket, and during the rotation of the connecting hoop, it drives the support plate and the control box to rotate together.

[0023] A baffle is installed on top of the control cabinet. The baffle is used for further protection of the control cabinet.

[0024] The shielding box is a hollow cylindrical structure, with its axis collinear with the axis of the support frame. Besides protecting the control cabinet, the shielding box can also be used to further secure the support frame.

[0025] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0026] This utility model relates to a GNSS displacement monitoring station for reservoir dam displacement monitoring. The device uses a telescopic component to allow the support plate and control box to move up and down on the bracket, making it easier for operators to maintain the components in the control box and making it more convenient to operate and use.

[0027] Meanwhile, a shielding box is installed on the lower support of this device. When it rains, the telescopic component keeps the control box inside, further protecting it from prolonged contact with rainwater, which could damage the control box. Rainwater entering the control box could also affect the internal components and consequently the use of the device. Attached Figure Description

[0043] Example 1

[0044] like Figure 1 As shown, this device includes a support frame 1, on which a solar panel 2, an antenna 3, and a control box 7 are mounted. The support frame 1 is divided into an upper support frame 6 and a lower support frame 5 from top to bottom. The lower end of the lower support frame 5 is connected to the ground 17. A connecting ring 4 is fitted onto the support frame 1, allowing it to slide up and down. The side of the connecting ring 4 is connected to a support plate 8. The control box 7 is connected to the support plate 8. The structure between the connecting ring 4 and the support plate 8 is as follows: Figure 2 As shown, the connecting ring 4 is fitted onto the bracket 1.

[0045] In some embodiments, the control chassis 7 and the support plate 8 are connected by bolts.

[0046] In some embodiments, the bracket 1 is provided with a fixed slide groove, which is vertically arranged. The connecting ring 4 is provided with a slider, which is located in the fixed slide groove to prevent the connecting ring 4 from separating from the bracket 1. At the same time, the slider can move up and down in the fixed slide groove.

[0047] In some embodiments, a telescopic assembly is provided on the lower bracket 5, and the telescopic assembly is connected to the support plate 8. The telescopic assembly drives the connecting ring 4, the support plate 8, and the control housing 7 to slide up and down on the bracket 1 by telescoping. The telescopic assembly can have various structures, as long as it can drive the support plate 8 and the control housing 7 to move up and down.

[0048] During normal use, the support plate 8 and the control box 7 are located on the upper bracket 6. When maintenance is required, the support plate 8 and the control box 7 are located on the lower bracket 5, which facilitates quick maintenance by operators.

[0049] In some embodiments, such as Figure 3 As shown, the upper bracket 6 and the lower bracket 5 are provided with a communicating slide groove 19. A sliding member 20 is provided on the slide groove 19, and a bracket slider 201 is provided on the sliding member 20. The bracket slider 201 is located inside the slide groove 19. The bracket slider 201 drives the sliding member 20 to move up and down in the slide groove 19. The sliding member 20 is connected to the support plate 8. One end of the data cable passes through the sliding member 20 and connects to the module inside the control box 7. The other end of the data cable is located inside the bracket 1. When the support plate 8 moves up and down, the support plate 8 drives the sliding member 20 to move together, and the sliding member 20 drives the data cable to move up and down together, avoiding the connection between the control box 7 and the data cable being pulled. Preferably, the sliding member 20 is provided with a fixing clip. The fixing clip is an existing structure. The elastic clip includes a spring connected to the inner ring of the sliding member and a fixing block. The spring drives the fixing block to contact the data cable, thereby fixing the connection between the data cable and the sliding member 20.

[0050] like Figure 4 As shown, the upper end of the slide groove 19 is connected to one end of the first telescopic plate 202, and the other end of the first telescopic plate 202 is connected to the slider 20. The lower end of the slide groove 19 is connected to one end of the second telescopic plate 203, and the other end of the second telescopic plate 203 is connected to the slider 20. When the slider 20 slides in the slide groove 19, the lengths of the first telescopic plate 202 and the second telescopic plate 203 are adjusted. Both the first telescopic plate 202 and the second telescopic plate 203 are structures in which multiple connecting plates are sequentially connected. The internal connecting plates can slide out of adjacent connecting plates, thereby adjusting the overall length. This structure is an existing structure, and other structures that can achieve telescopic movement can be used as replacements. The first telescopic plate 202 and the second telescopic plate 203 cover the slide groove 19 to prevent the slide groove 19 from being exposed and affecting the protection of the data cables inside the bracket.

[0051] In some embodiments, a baffle 13 is provided above the control box 7. A second connecting ring is fitted on the bracket 1, and the second connecting ring can slide up and down on the bracket 1. The side of the second connecting ring is connected to the baffle 13. A slider is provided on the second connecting ring, and the slider is located in a fixed groove to prevent the baffle 13 from separating from the bracket 1. At the same time, the slider can move up and down in the fixed groove.

[0052] Example 2

[0053] Based on the above embodiment, a shielding box 16 is provided on the lower support 5. The upper end of the shielding box 16 is open and opposite to the support plate 8, and the lower end of the shielding box 16 is in contact with the ground 17. When it rains, the telescopic component keeps the control box 7 inside the control box 7, which further protects the control box 7 and prevents it from being in contact with rainwater for a long time, which could cause damage to the control box 7. Rainwater entering the control box 7 can affect the components inside the control box 7, thereby affecting the use of this device.

[0054] The telescopic assembly allows the control box 7 to be located inside the control box 7. This operation can be performed remotely or manually on-site.

[0055] like Figure 5 As shown, the side of the shield box 16 is provided with an opening, and a shield door 161 is provided on the opening. When the control box is located inside the shield box 16 and the operator needs to perform maintenance on the control box, the maintenance operation can be performed by opening the shield door.

[0056] Secondly, the barrier door 161 is a sensor-operated baffle, which is equipped with a sensing component, which can be a pressure sensor. When the support plate 8 and the control box 7 are on the sensor-operated baffle and in contact with it, the sensing component on the baffle receives the pressure information, causing the baffle to shorten. The support plate 8 and the control box 7 can then pass through the baffle and enter the barrier box. After the support plate 8 and the control box 7 enter the barrier box, the sensing component controls the baffle to extend, and the baffle blocks the opening at the top of the barrier box, thus better protecting the control box.

[0057] The sensing component can also be a distance sensor, used to obtain the distance between the support plate 8 and the top of the shield box. When the distance between the support plate 8 and the top of the shield box is 0, the sensing baffle shortens, and the support plate 8 and the control box 7 can enter the shield box through the sensing baffle. After the support plate 8 and the control box 7 enter the shield box, the sensing component controls the sensing baffle to extend.

[0058] In some embodiments, a drain pipe 18 is provided at the lower end of the shield box 16. When rainwater enters the shield box during the opening of the sensor baffle, the rainwater can be quickly discharged through the drain pipe to prevent rainwater from remaining in the shield box 16.

[0059] In some embodiments, the shielding box 16 is a hollow cylindrical structure, and the axis of the shielding box 16 is collinear with the axis of the support 1. The shielding box 16 is used to further fix the support bracket and prevent displacement.

[0060] Example 3

[0061] Based on the above embodiments, the telescopic component is a telescopic rod, the lower end of which is connected to the inner bottom of the shielding box 16, and the upper end of which is connected to the support plate 8.

[0062] In some embodiments, the telescopic assembly includes a first gear 9 and a second gear 10 connected to the support plate 8, and a third gear 14 connected to the lower bracket 5.

[0063] like Figure 6 As shown, the first gear component 9 is a horizontally arranged gear rod, and the second gear component 10 is a disc-shaped gear disk. The third gear component 14 is a vertically arranged gear rod, and the third gear component 14 is connected to the lower support 5 through an annular groove. The third gear component 14 rotates on the lower support 5 along the annular groove about the center line of the support 1.

[0064] The first gear 9 is located above and tangent to the second gear 10, and the third gear 14 is located on the side of the second gear 10 and tangent to it. The first gear 9 meshes with the second gear 10, and the third gear 14 meshes with the second gear 10.

[0065] When the first gear 9 rotates circumferentially, it acts on the second gear 10, causing the second gear 10 to rotate circumferentially. During the rotation of the second gear 10, it acts on the third gear 14, causing the second gear 10 to move up and down along the straight line where the third gear is located.

[0066] In use, when the second gear 10 is positioned above the third gear 14, as follows: Figure 7 As shown, the support plate 8 and the control box 7 are located on the upper bracket 6.

[0067] When the second gear 10 is located below the third gear 14, as Figure 8 As shown, the support plate 8 and the control box 7 are located in the shield box 16.

[0068] In some embodiments, the connecting clamp 15 is detachably connected to the lower bracket 5. The connecting clamp 15 is fitted onto the bracket 1, and a slider is provided on the connecting clamp 15. The slider is located within a fixed groove, allowing the connecting clamp 15 to slide up and down on the bracket 1. Figure 9 As shown, the connecting clamp 15 is connected to the second gear component 10, and the slider can move up and down in the fixed groove. This prevents the connecting clamp 15 from separating from the bracket 1.

[0069] In some embodiments, the support plate 8 is connected to the first gear component 9 via a first connecting rod 12, and the second gear component 10 is connected to the support plate 8 via a second connecting rod 11.

[0070] In some embodiments, such as Figure 10 As shown, a protective cover 81 is connected to the lower end of the support plate 8. The first gear component 9, the second gear component 10, and the third gear component 14 are located inside the protective cover 81. When the operator needs to adjust the telescopic component, the protective cover 81 is opened. At other times, the protective cover is locked to prevent other personnel from opening the protective cover.

Furthermore, the term "connection" used in this document, unless otherwise specified, can refer to a direct connection or an indirect connection via other components.
