Description

Technical Field

[0001] This utility model relates to the field of surveying and mapping technology, and in particular to a GNSS and prism coaxial assembly for deformation monitoring. Background Technology

[0002] Surface displacement observation is one of the main means of monitoring the safety status of dams and slopes. With the gradual maturity of GNSS high-precision deformation monitoring technology, the use of GNSS systems, represented by Beidou, to realize all-weather, all-time, and fully automated continuous monitoring of dam and slope surface displacement has formed a trend of large-scale application in the industry.

[0003] A search revealed that existing technology discloses a bracket for installing GNSS deformation monitoring equipment on a surface displacement observation pier (publication number: CN218566414U). The bracket is a cage-like structure consisting of a base, a top plate, and multiple columns. The base and top plate are connected by multiple columns, and the center lines of the base and top plate are coaxially arranged. The cage-like structure can accommodate a total station or a prism. The center of the base can be fixedly connected to the total station or prism, and the center of the top of the top plate can be fixed to a GNSS antenna.

[0004] In existing technologies, in order to avoid the columns obstructing the observation line of the total station, the number of columns is increased or decreased and the position of the columns is adjusted to avoid obstruction. Even under these circumstances, it is impossible to completely avoid the columns obstructing the line of sight. Therefore, avoiding the columns from obstructing the observation line while ensuring the installation effect is an urgent problem to be solved.

[0005] To this end, we propose a GNSS and prism coaxial assembly for deformation monitoring. Utility Model Content

[0006] The present invention mainly solves the technical problem that the above-mentioned column will block the observation line of sight, and provides a GNSS and prism coaxial assembly for deformation monitoring.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a GNSS and prism coaxial assembly for deformation monitoring, comprising:

[0008] Two parallel end plates are provided, and several support columns are installed between the two end plates for support. The support columns and the end plates together form a cage frame.

[0009] The mounting assembly is located at the bottom of the end plate for adjusting the position of the end plate. The mounting assembly includes a mounting base plate, a thrust groove, a sliding block, and a rib. The mounting base plate is rotatably mounted at the bottom of the lower end plate. The mounting base plate has several thrust grooves. The sliding block is elastically connected to the end plate. The rib is fixedly connected to the sliding block and can be inserted into the thrust groove to lock the end plate.

[0010] In a preferred embodiment of this utility model, the mounting plate is formed into a circular plate, and a shaft hole is provided at the center of the mounting plate. A rotating shaft is fixedly installed at the bottom of the end plate, and the rotating shaft is rotatably disposed in the shaft hole.

[0011] In a preferred embodiment of this utility model, the thrust groove is formed on the upper end face of the mounting base plate, and multiple thrust grooves are distributed in a ring array.

[0012] In a preferred embodiment of this utility model, the rib is integrally formed with the sliding block, the rib is located at the bottom of the sliding block, the rib is a semi-cylinder, and the thrust groove is used in conjunction with the rib.

[0013] In a preferred embodiment of this utility model, the mounting assembly further includes a spring and a sliding channel. The sliding channel is formed at the bottom of the end plate. The spring is fixedly connected to the sliding block, and the sliding block is elastically disposed in the sliding channel by the spring.

[0014] In a preferred embodiment of this utility model, the sliding block is formed into a rectangular block, the sliding channel is a rectangular groove adapted to the sliding block, the sliding block and the sliding channel are slidably connected, and the spring is a deformable rectangular plate that extends obliquely upward toward the sliding block.

[0015] In a preferred embodiment of the present invention, the mounting assembly further includes ear plates, with one ear plate fixedly mounted on each side of the sliding block, and the ear plates being slidably connected to the sliding channel.

[0016] This invention provides a coaxial GNSS and prism assembly for deformation monitoring. It offers the following advantages:

[0017] 1. This GNSS and prism coaxial assembly for deformation monitoring, by rotating a lower end plate to a mounting base plate, and by rotating the cage structure formed by the end plate and support column as a whole, adjusts the observation position of the total station to avoid the total station's rotation relative to the lower end plate being blocked by the support column, ensuring that the observation is not interfered with and avoiding obstruction of the line of sight. The overall position adjustment and locking of the cage structure can be achieved by pushing the protruding rib into the thrust groove through the elastically connected sliding block.

[0018] 2. This GNSS and prism coaxial assembly for deformation monitoring features a sliding channel. A sliding block is slidably positioned within the sliding channel, and a spring on top of the sliding block provides elasticity by contacting the top surface of the sliding channel. This allows the sliding block to apply pressure close to the mounting plate to the rib, thus securing the rib stably within the thrust groove and locking it to the end plate and mounting plate. Ear plates ensure the stability of the sliding block's movement. Side grooves adapted to the ear plates are provided on both sides of the sliding channel, with the height of the side grooves less than the thickness of the end plate, preventing the sliding block from detaching from the end plate. During operation, simply push the sliding block upwards; the sliding block and ear plates slide upwards within the sliding channel, causing the rib to exit the thrust groove. Rotating the end plate adjusts the position. Once the appropriate angle is reached, releasing the sliding block causes the spring force to push the sliding block downwards, locking the rib into the corresponding thrust groove. The operation is simple and easy to use. Attached Figure Description

[0025] A GNSS and prism coaxial assembly for deformation monitoring, such as Figure 1 and Figure 2 As shown, it includes:

[0026] Two parallel end plates 10 are supported by several support columns 11 installed between them. The support columns 11 and the end plates 10 together form a cage frame. It should be noted that the support columns 11 are locked to the end plates 10 by bolts. Taking three support columns 11 as an example, the GNSS is fixedly installed on the top of the upper end plate 10, and the prism or total station is fixedly installed on the top surface of the lower end plate 10. The prism and the GNSS are coaxially distributed.

[0027] like Figure 2 , Figure 3 and Figure 4 As shown, the mounting assembly is set at the bottom of the end plate 10 to adjust the position of the end plate 10. The mounting assembly includes a mounting base plate 20, a thrust groove 21, a sliding block 22, and a rib 23. The mounting base plate 20 is rotatably set at the bottom of the lower end plate 10. The mounting base plate 20 has several thrust grooves 21. The sliding block 22 is elastically connected to the end plate 10. The rib 23 is fixedly connected to the sliding block 22. The rib 23 can be inserted into the thrust groove 21 to lock the end plate 10. The mounting base plate 20 forms a circular plate. A shaft hole is opened at the center of the mounting base plate 20. A rotating shaft is fixedly installed at the bottom of the end plate 10. The rotating shaft is rotatably set in the shaft hole. The thrust groove 21 is opened on the upper end face of the mounting base plate 20. Multiple thrust grooves 21 are distributed in a ring array. The rib 23 is integrally formed with the sliding block 22. The rib 23 is located at the bottom of the sliding block 22. The rib 23 is a semi-cylinder. The thrust groove 21 and the rib 23 cooperate with each other.

[0028] In this scheme, since the total station's surveying angle needs to be adjusted, and the fixed support column 11 may affect the observation and obstruct the line of sight, the observation position of the total station is adjusted by rotating the lower end plate 10 to the mounting base plate 20. This is done by rotating the cage structure formed by the end plate 10 and the support column 11 to avoid the total station being blocked by the support column 11 when rotating relative to the lower end plate 10, thus ensuring that the observation is not disturbed and the line of sight is not obstructed. The overall position adjustment and locking of the cage structure can be achieved by pushing the protruding rib 23 into the thrust groove 21 through the elastically connected sliding block 22.

[0029] like Figure 4 and Figure 5 As shown, the mounting assembly also includes a spring 25 and a sliding channel 26. The sliding channel 26 is opened at the bottom of the end plate 10. The spring 25 is fixedly connected to the sliding block 22. The sliding block 22 is elastically set in the sliding channel 26 through the spring 25. The sliding block 22 forms a rectangular block. The sliding channel 26 is a rectangular groove that fits the sliding block 22. The sliding block 22 is slidably connected to the sliding channel 26. The spring 25 is a deformable rectangular plate. The spring 25 extends obliquely upward towards the sliding block 22. The mounting assembly also includes an ear plate 24. An ear plate 24 is fixedly installed on each side of the sliding block 22. The ear plate 24 is slidably connected to the sliding channel 26.

[0030] In this solution, to address the installation issue between the sliding block 22 and the end plate 10, a sliding channel 26 is created. The sliding block 22 is slidably positioned within the sliding channel 26. A spring 25 on the top of the sliding block 22 abuts against the inner top surface of the sliding channel 26, providing elasticity. This allows the sliding block 22 to apply pressure to the protruding rib 23, close to the mounting plate 20. Consequently, the protruding rib 23 is stably engaged within the thrust groove 21, locking the end plate 10 and the mounting plate 20. The ear plate 24 ensures the stability of the sliding block 22's movement. Side grooves adapted to the ear plates 24 are provided on both sides of the 26. The height of the side grooves is less than the thickness of the end plate 10, thus ensuring that the sliding block 22 will not detach from the end plate 10. During operation, simply push the sliding block 22 upward. The sliding block 22 and the ear plates 24 slide upward in the sliding channel 26, and the protruding rib 23 exits from the thrust groove 21. Rotate the end plate 10 to adjust the position. After reaching the appropriate angle, release the sliding block 22. The elastic force of the spring 25 pushes the sliding block 22 downward, causing the protruding rib 23 to engage in the corresponding thrust groove 21 to achieve locking. The operation is simple and easy to use.

[0031] The bottom of the mounting plate 20 has mounting holes, which can be used to fix the mounting plate 20 to the building, such as a dam, total station, and GNSS. These are well-known existing technologies, and the specific models and specifications are not limited here.

[0032] The working principle of this utility model is as follows: The lower end plate 10 is rotatably connected to the mounting base plate 20. By rotating the cage structure formed by the end plate 10 and the support column 11 as a whole, the observation position of the total station is adjusted to avoid the total station being blocked by the support column 11 when rotating relative to the lower end plate 10, thus ensuring that the observation is not disturbed and the line of sight is not obstructed. The sliding block 22 can be pushed up, and the sliding block 22 and the ear plate 24 slide up in the sliding channel 26. The protruding rib 23 exits from the thrust groove 21. The position can be adjusted by rotating the end plate 10. After reaching the appropriate angle, the sliding block 22 is released. The elastic force of the spring 25 pushes the sliding block 22 down, so that the protruding rib 23 is locked into the thrust groove 21 at the corresponding position.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
