Description

Technical Field

[0001] The utility model relates to the technical field of measuring instruments, in particular to a GNSS receiver quick installation structure. Background Art

[0002] A GNSS receiver is an instrument that receives satellite signals for navigation and positioning. It is usually composed of an antenna, a baseband processor, a radio frequency front end, a data processing unit, and a power supply. A GNSS receiver receives satellite signals to determine the user's geographic location and is mainly used for precision geodetic and engineering measurements. This type of instrument mainly uses carrier phase observations for relative positioning, with high positioning accuracy. In addition, a GNSS receiver can mainly serve as a receiver that receives two or more GNSS system signals at the same time; GNSS receivers are widely used in highway and land surveying. GNSS receivers are generally installed on a tripod, and they also need to be leveled during installation. However, the leveling speed is limited by the operator's experience. For those who are inexperienced, the slow installation and leveling speed greatly prolongs their use time and reduces the measurement speed. In addition, it is inconvenient to install it on the hull when measuring on water, and its practicality is poor. Utility Model Content

[0003] 1. Technical issues to be solved

[0004] In view of the deficiencies in the prior art, the utility model provides a GNSS receiver quick installation structure, which solves the problem that the leveling speed of the GNSS receiver when in use is limited by the operator's experience. For those with insufficient experience, the slow installation and leveling speed greatly prolongs its use time and reduces the measurement speed. In addition, it is inconvenient to install it on the hull when measuring on the water, resulting in poor practicality.

[0005] (II) Technical solution

[0006] To achieve the above purpose, the utility model is implemented through the following technical solutions: a GNSS receiver quick installation structure, including a receiver body with a horizontal calibration bubble on the top and a support rod, a support frame with a bottom clamp is provided on the side of the support rod, a quick leveling assembly is connected between the support frame and the support rod, and a counterweight block is connected to the bottom end of the support rod to keep it suspended vertically;

[0007] The quick leveling assembly includes a top clamp and a spherical cylinder sleeved on the outer wall of the support rod. The outer wall of the spherical cylinder is sleeved with an annular sleeve that can slide relative to it at any angle. Anti-slip rings are fixed at both ends of the spherical cylinder. The outer wall of the annular sleeve is provided with a connecting block, which is connected to the end of the support frame by a connecting screw running through the inside.

[0008] Furthermore, there are three connecting blocks in total, including two fixed connecting blocks and one movable connecting block. The outer wall of the annular sleeve is provided with a slide groove compatible with the movable connecting block. The movable connecting block can adjust the position of the support frame through the slide groove, and then the bottom clamp on the support frame can be fixed on the railing of the hull, and together with another support frame whose position cannot be adjusted, the whole is supported, which is beneficial to improve the stability of installation on the hull railing.

[0009] Furthermore, the connecting screw is T-shaped, with external threads only near the end. When the connecting screw is tightened, it squeezes the opening of the connecting block, thereby clamping the end of the support frame to limit its rotation. By adjusting the relative angle between the connecting block and the support frame, the overall level of the receiver body is also adjusted, so that it is within the movable range of the annular sleeve when vertical, which is convenient for quick and level installation. At the same time, the unscrewing of the connecting screw can also disassemble and maintain the idle or damaged support frame.

[0010] Furthermore, the bottom clamp is rotatably connected to the support frame via a nail-shaped structure penetrating the interior thereof.

[0011] Furthermore, the counterweight is a conical structure with the tip pointing downward, and a laser lamp is installed at the center of the bottom end, so as to facilitate rapid centering operation when the GNSS receiver is installed on the ground.

[0012] Furthermore, a socket adapted to the support rod is provided at the center of the top of the counterweight block, and a middle clamp for fixing the support rod is connected to the top of the counterweight block.

[0013] Furthermore, the support frame is an arc-shaped structure, and the counterweight block can be suspended in the air when the receiver body is supported upright.

[0014] (III) Beneficial effects

[0015] The utility model provides a GNSS receiver quick installation structure, which has the following beneficial effects:

[0016] 1. The GNSS receiver has a quick installation structure. The top clamp is fixed to the outer wall of the support rod and close to the receiver body. The spherical tube is then sleeved on the outer wall of the support rod and located at the bottom of the top clamp. The counterweight is fixed to the bottom of the support rod to complete the installation operation. The GNSS receiver is suspended in the air through three support frames and erected vertically by itself to complete the leveling of the receiver body. At the same time, the bottom clamp on the support frame can fix the device to the railing of the hull, which simplifies the installation operation of the equipment during water measurement without damaging the hull.

[0017] 2. The GNSS receiver has a quick installation structure. The counterweight moves the center of gravity of the GNSS receiver downward so that it always has a vertical tendency. When the receiver body is suspended, the annular sleeve connecting it to the support frame slides on the outer wall of the spherical cylinder under the gravity of the counterweight, thereby satisfying the vertical state of the receiver body, facilitating the rapid completion of the leveling installation operation of the GNSS receiver. Even if the device is shaken by the impact of external objects, it can quickly return to the vertical state, and has good practicality.

[0018] 3. The GNSS receiver has a quick installation structure. The movable connection block can adjust the position of the support frame through the slide groove, and then the bottom clamp on the support frame can be fixed to the railing of the hull, and together with another support frame whose position cannot be adjusted, the whole is supported, which is beneficial to improve the stability of the installation and the hull railing.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The utility model provides a GNSS receiver quick installation structure, such as Figure 1-4As shown, it includes a receiver body 1 with a horizontal calibration bubble on the top and a support rod 2, a support frame 3 with a bottom clamp 12 is provided on the side of the support rod 2, a quick leveling assembly is connected between the support frame 3 and the support rod 2, and a counterweight block 11 is connected to the bottom end of the support rod 2 to keep it suspended vertically;

[0026] The quick leveling assembly includes a top clamp 4 and a spherical tube 5 sleeved on the outer wall of the support rod 2. The spherical tube 5 is a spherical structure with a channel for the support rod 2 to pass through. The outer wall of the spherical tube 5 is sleeved with an annular sleeve 6 that can slide relative to it at any angle. Anti-slip rings 7 are fixed at both ends of the spherical tube 5. A connecting block 8 is provided on the outer wall of the annular sleeve 6. The connecting block 8 is connected to the end of the support frame 3 through a connecting screw 10 running through the inside thereof. The top clamp 4 is fixed to the outer wall of the support rod 2 and close to the receiver body 1, and then the spherical tube 5 is sleeved on the outer wall of the support rod 2 and is located at the bottom of the top clamp 4. The counterweight 11 is fixed to the bottom of the support rod 2. The installation operation can be completed simply and quickly. The GNSS receiver and the support rod 2 are suspended in the air through three support frames 3. The counterweight block 11 moves the center of gravity of the GNSS receiver downward so that it always has a vertical tendency. When the receiver body 1 is suspended in the air, the annular sleeve 6 connected to the support frame 3 slides on the outer wall of the spherical cylinder 5 under the action of the gravity of the counterweight block 11, thereby satisfying the vertical state of the receiver body 1, which is convenient for quickly completing the leveling installation operation of the GNSS receiver. Even if the equipment is shaken by the impact of external objects, it can quickly restore to the vertical state, which is convenient for dealing with the occasional shaking of the hull during water operations, and has good practicality.

[0027] Specifically, there are three connecting blocks 8, including two fixed connecting blocks 81 and one movable connecting block 82. The outer wall of the annular sleeve 6 is provided with a slide groove 9 adapted to the movable connecting block 82. The movable connecting block 82 can adjust the position of the support frame 3 through the slide groove 9, and then the bottom clamp 12 on the support frame 3 can be fixed on the railing of the hull, and together with another support frame 3 whose position cannot be adjusted, the whole is supported, which is conducive to improving the stability of installation on the hull railing.

[0028] Specifically, the connecting screw 10 is T-shaped, and only an external thread is provided near its end. When the connecting screw 10 is tightened, it squeezes the opening of the connecting block 8, thereby clamping the end of the support frame 3 to limit its rotation. By adjusting the relative angle between the connecting block 8 and the support frame 3, the overall level of the receiver body 1 is also adjusted (that is, the receiver body 1 is roughly leveled), so that it is convenient to be within the movable range of the annular sleeve 6 when it is vertical, which is convenient for quick and level installation. At the same time, the unscrewing of the connecting screw 10 can also disassemble and maintain the idle or damaged support frame 3.

[0029] Specifically, the bottom clamp 12 is rotatably connected to the support frame 3 via a nail-shaped structure penetrating the inside thereof.

[0030] Specifically, the counterweight 11 is a conical structure with the tip pointing downward, and a laser lamp is installed at the center of the bottom end thereof, so as to facilitate rapid centering operation when the GNSS receiver is installed on the ground.

[0031] Specifically, a socket adapted to the support rod 2 is provided at the center of the top of the counterweight block 11 , and a middle clamp for fixing the support rod 2 is connected to the top of the counterweight block 11 .

[0032] Specifically, the support frame 3 is an arc-shaped structure, and the counterweight 11 can be suspended in the air when the receiver body 1 is supported to stand upright.

[0033] Working principle: When in use, fix the top clamp 4 to the outer wall of the support rod 2 and close to the receiver body 1, then put the spherical tube 5 on the outer wall of the support rod 2 and located at the bottom of the top clamp 4, and fix the counterweight 11 to the bottom of the support rod 2 to complete the installation operation. The GNSS receiver and the support rod 2 are suspended in the air through three support frames 3, and the counterweight 11 moves the center of gravity of the GNSS receiver downward so that it always has a vertical tendency. When the receiver body 1 is suspended in the air, the annular sleeve 6 connected to the support frame 3 slides on the outer wall of the spherical tube 5 under the action of the gravity of the counterweight 11, thereby satisfying the vertical state of the receiver body 1, which is convenient for quickly completing the leveling installation operation of the GNSS receiver, and even if the device is shaken by the impact of external objects, it can quickly restore the vertical state.
