Description

Technical Field

[0001] The utility model belongs to the technical field of unmanned aerial vehicles, and specifically relates to a terrain surveying and mapping unmanned aerial vehicle for road and bridge construction. Background Art

[0002] Road and bridge construction is an important infrastructure construction in my country, which is related to the people's livelihood. When constructing roads and bridges, it is first necessary to use surveying and mapping equipment to conduct terrain surveying. Surveying and mapping uses relevant technologies to select existing feature points and boundaries on the ground and obtain graphics and location information reflecting the current status of the ground through measurement methods for the purpose of engineering construction, planning and design, and administrative management. In the process of surveying and mapping, since drones are widely used nowadays, the use of drones equipped with surveying and mapping equipment can carry out very flexible and effective surveying and mapping processing.

[0003] Most existing drones do not have a buffer protection structure when in use, which makes it easy to cause damage when colliding with objects, and the propeller blades are generally directly exposed to the air and are prone to damage;

[0004] In order to solve the above problems, this application proposes a terrain mapping drone for road and bridge construction. Utility Model Content

[0005] In view of the problems in the related technologies, the utility model proposes a terrain surveying and mapping UAV for road and bridge construction to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A terrain mapping UAV for road and bridge construction comprises a body, two arms are installed on both sides of the body, a power box is installed at one end of the arm, propeller blades are installed in the power box, a protective mechanism is provided on the outside of the power box, isolation nets are installed on the top inner wall and the bottom inner wall of the power box, a supporting mechanism is installed at the bottom of the body, a mounting plate is installed at the bottom of the body, a push rod motor is installed at the bottom of the mounting plate, a mounting seat is fixedly installed on the output shaft of the push rod motor, and a rotatable mapping camera is installed in the mounting seat.

[0008] Preferably, the support mechanism comprises four symmetrically arranged support columns, the bottom ends of the support columns are slidably connected to support rods, and the bottom ends of two support rods on the same side are fixedly mounted with the same placement rod.

[0009] The support rod is slidably connected to the support column, so that the machine body can be supported by the placement rod, and there is an up and down buffering activity distance during impact.

[0010] Preferably, a buffer groove is provided at the bottom end of the support column, the inner wall of the buffer groove is slidably connected to the support rod, a buffer spring is fixedly installed on the top inner wall of the buffer groove, and the bottom end of the buffer spring is fixedly connected to the top end of the support rod.

[0011] The buffer spring in the buffer groove can provide a buffering effect on the support rod and can be reset to maintain continuous support and buffering.

[0012] Preferably, a damper is installed between the top inner wall of the buffer groove and the top end of the support rod.

[0013] The setting of the damper can reduce the rebound force of the buffer spring when it rebounds, thereby achieving the buffering effect of the buffer spring.

[0014] Preferably, limiting grooves are provided on the inner walls on both sides of the buffer groove, limiting blocks are slidably connected to the inner walls of the limiting grooves, and the limiting blocks are fixedly connected to the support rods.

[0015] The sliding connection between the limiting groove and the limiting block can limit the support rod to prevent the support rod from falling.

[0016] Preferably, the protective mechanism comprises an annular rubber pad, and the annular rubber pad is installed on the outside of the power box.

[0017] The provision of the annular rubber pad can facilitate the protection of the power box to prevent the body from being damaged due to excessive force when colliding with an object, and can also prevent the propeller blades in the power box from being damaged.

[0018] Preferably, an arc-shaped sponge is installed on the top of the body.

[0019] The setting of the arc-shaped sponge can protect the top of the body to prevent damage to the body due to impact or falling objects from above.

[0020] In summary, the technical effects and advantages of the utility model are as follows:

[0021] Through the sliding connection between the support rod and the support column, and the buffering effect of the buffer spring on the support rod and the placement rod, the bottom of the body can be supported and protected, and the rotatable surveying and mapping camera can be supported and protected.

[0022] By setting up the annular rubber pad and the arc-shaped sponge, the surrounding and top of the fuselage can be isolated and protected to prevent the fuselage from impacting other objects. At the same time, the setting of the isolation net can prevent foreign objects from touching the propeller blades and causing damage to the propeller blades. BRIEF DESCRIPTION OF THE DRAWINGS
