Description

Technical Field

[0001] This utility model relates to the field of engineering testing technology, and in particular to a surveying device for engineering testing. Background Technology

[0002] Surveying equipment, simply put, refers to the instruments and devices designed and manufactured for surveying operations, including data acquisition, processing, and output. These instruments are used in various aspects of surveying work during the planning, design, construction, and operation management phases of municipal engineering projects, such as orientation, distance measurement, angle measurement, height measurement, mapping, and photogrammetry.

[0003] Chinese utility model patent CN202120946979.7 discloses a drone mapping device, including a fuselage, landing gear, and a battery. A detection radar is installed on one side of the fuselage, and a gimbal is installed at the bottom of the fuselage. A camera is installed below the gimbal. The advantages are: by setting up a detection radar and an early warning module, the detection radar can detect high altitudes and send the detection results to the main control chip. The main control chip controls the early warning module to issue a signal, which is then transmitted to the terminal via a signal transmitter. This facilitates timely operation of the drone by staff, preventing collisions and potential safety hazards. The inclusion of support rods and load-bearing rods allows the support rods to support the load-bearing rods. During landing, the load-bearing rods and landing gear make contact with the ground, increasing the contact area and preventing the drone from collapsing and damaging it, thus ensuring the drone's lifespan.

[0004] Regarding the aforementioned technologies, the inventors believe that the following shortcomings exist: While the combination of cameras and detection radar can achieve the mapping effect, it still has some deficiencies. Due to the complex outdoor environment and terrain, drones are prone to tilting during landing. Additionally, due to the speed during landing, the impact force upon landing can cause damage to the drone or mapping camera, affecting the engineering mapping process. Furthermore, fixedly installed mapping devices are not easy to replace quickly after damage, affecting the efficiency of mapping. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a surveying device for engineering testing.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a surveying device for engineering inspection, comprising a fixed plate, a drone bracket provided at the top of the fixed plate, a first telescopic rod installed at the bottom of the fixed plate, a first spring sleeved on the outer wall of the first telescopic rod, a support plate fixedly connected to the bottom of the first telescopic rod, a buffer assembly provided at the bottom of the support plate, a surveying instrument installed at the bottom of the fixed plate, slots provided on both sides of the bottom of the drone bracket, and a connecting assembly provided between the drone bracket and the fixed plate.

[0007] By adopting the above technical solution, the connection components can be easily installed on the drone, facilitating replacement and maintenance. The buffer components can provide multiple shock absorptions, effectively preventing damage to the drone body or surveying instrument during landing and providing protection for the surveying instrument.

[0008] Furthermore, the buffer assembly includes inner grooves formed on both sides inside the support plate, with sliders slidably connected to both sides of the inner grooves, and a second spring fixedly connected between the sliders and the inner wall of the inner grooves. A protruding post is slidably connected to the bottom of the support plate, with the bottom end of the protruding post penetrating the bottom side wall of the support plate and fixedly connected to a buffer plate. A third spring is sleeved on the outer end of the protruding post on the support plate.

[0009] By adopting the above technical solution, when the drone lands on the ground, the buffer plate, protruding column and third spring provide primary shock absorption for the support plate and fixed plate. When the protruding column moves upward, it will squeeze the sliders on both sides. The sliders slide along the inner groove and compress the second spring, thereby providing secondary shock absorption for the support plate and fixed plate. With the superposition of multiple shock absorption effects, damage to the drone body or mapping instrument can be effectively avoided when landing.

[0010] Furthermore, the protrusion located at one end of the groove is trapezoidal, and the trapezoidal end of the protrusion is connected to the slider.

[0011] By adopting the above technical solution, and by setting a convex post and a slider that are connected in a mating manner, the convex post can separate the two sliders when it moves.

[0012] Furthermore, side blocks are fixedly connected to both ends of the support plate, and side guard plates are rotatably connected inside the side blocks. One end of the side guard plate is hinged to one end of the second telescopic rod, and the other end of the second telescopic rod is hinged to the bottom side of the fixed plate. A fourth spring is sleeved on the outer wall of the second telescopic rod.

[0013] By adopting the above technical solution, the side blocks and side guards set on both sides of the support plate can provide auxiliary support for the fixing plate on uneven ground, prevent the fixing plate from tilting and protect the surveying instrument, while the fourth spring can further provide shock absorption for the fixing plate.

[0014] Furthermore, the connecting assembly includes a fixing seat mounted on the top of the fixing plate. The fixing seat has a receiving groove inside. A pull rod is slidably connected to one side of the receiving groove. One end of the pull rod is rotatably connected to one end of a connecting rod. The other end of the connecting rod is fixedly connected to one end of a locking block. The locking block is rotatably connected inside the receiving groove. A limiting sleeve is installed inside the receiving groove. A fifth spring is sleeved inside the limiting sleeve. One end of the fifth spring is fixedly connected to one end of the pull rod.

[0015] By adopting the above technical solution, by pulling the pull rod in the connecting assembly, the pull rod moves along the receiving groove, and the pull rod pulls the fifth spring to stretch. The pull rod pulls the locking block to rotate through the connecting rod, and then the bottom of the drone bracket is inserted into the receiving groove along the top of the receiving groove. When the bottom of the drone bracket is pressed against the limiting sleeve, the pull rod is released, the fifth spring resets and drives the pull rod to reset. Under the action of the fifth spring, the pull rod pulls the locking block to rotate through the connecting rod. The locking block rotates and engages with the locking groove, thereby fixing the drone bracket in the fixed base, which facilitates quick and easy installation on the drone and makes it easy to disassemble and use.

[0016] Furthermore, the card block is L-shaped, and the card block is connected to the card slot, with one end of the drone bracket inserted into the top of the receiving slot.

[0017] By adopting the above technical solution, a locking block and a locking slot are set up for mutual connection. The locking block can move from the locking slot, thereby fixing the position of the drone bracket.

[0018] In summary, this utility model has the following beneficial effects:

[0019] 1. In this application, the pull rod in the connecting assembly moves along the receiving groove, pulls the fifth spring to stretch, and pulls the locking block to rotate through the connecting rod. Then, the bottom of the drone bracket is inserted into the receiving groove along the top of the receiving groove. When the bottom of the drone bracket is pressed against the limiting sleeve, the pull rod is released, the fifth spring resets and drives the pull rod to reset. Under the action of the fifth spring, the pull rod pulls the locking block to rotate through the connecting rod. The locking block rotates and engages with the locking groove, thereby fixing the drone bracket in the fixing base. This makes it easy and quick to install on the drone and easy to disassemble and use.

[0020] 2. In this application, when the UAV lands on the ground, the buffer plate, protruding column and third spring provide primary shock absorption for the support plate and fixed plate. When the protruding column moves upward, it will squeeze the sliders on both sides. The sliders slide along the inner groove and compress the second spring, thereby providing secondary shock absorption for the support plate and fixed plate. The support plate pushes the first telescopic rod to retract and compresses the first spring, thereby providing a third shock absorption for the fixed plate. With the superposition of multiple shock absorption effects, damage to the UAV body or mapping camera can be effectively avoided when landing.

[0021] 3. In this application, the side blocks and side guards set on both sides of the support plate can provide auxiliary support for the fixing plate on uneven ground, prevent the fixing plate from tilting and protect the surveying instrument, while the fourth spring can further provide shock absorption for the fixing plate.

[0026] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0027] like Figure 1-3As shown in the embodiment of this application, a surveying device for engineering testing is disclosed, including a fixed plate 1, a drone bracket 2 is provided at the top of the fixed plate 1, a first telescopic rod 4 is installed at the bottom of the fixed plate 1, a first spring 41 is sleeved on the outer wall of the first telescopic rod 4, a support plate 5 is fixedly connected to the bottom of the first telescopic rod 4, a buffer assembly 6 is provided at the bottom of the support plate 5, a surveying instrument 3 is installed at the bottom of the fixed plate 1, slots 21 are provided on both sides of the bottom of the drone bracket 2, and a connecting assembly 8 is provided between the drone bracket 2 and the fixed plate 1.

[0028] The buffer assembly 6 includes inner grooves 61 formed on both sides inside the support plate 5. Slider 62 is slidably connected to both sides of the inner groove 61. A second spring 64 is fixedly connected between the slider 62 and the inner wall of the inner groove 61. A protrusion 63 is slidably connected to the bottom of the support plate 5. The bottom end of the protrusion 63 penetrates the bottom side wall of the support plate 5 and is fixedly connected to a buffer plate 65. A third spring 66 is sleeved on the outer end of the protrusion 63. When the protrusion 63 is subjected to force, it can move upward and squeeze the two sliders 62. When the slider 62 moves, it will compress the second spring 64. Under the reaction force of the second spring 64, it can provide a shock absorption effect for the protrusion 63.

[0029] The protrusion 63 is located at one end of the groove and is trapezoidal. The trapezoidal end of the protrusion 63 is connected to the slider 62. The trapezoidal protrusion 63 can fit more closely to the outer wall of the slider 62, making the protrusion 63 press the two sliders 62 more smoothly.

[0030] Side blocks 7 are fixedly connected to both ends of the support plate 5. Side guard plates 71 are rotatably connected inside the side blocks 7. The side blocks 7 and side guard plates 71 on both sides of the support plate 5 can provide auxiliary support for the fixed plate 1 on uneven ground. One end of the side guard plate 71 is hinged to one end of the second telescopic rod 72. The other end of the second telescopic rod 72 is hinged to the bottom side of the fixed plate 1. A fourth spring 73 is sleeved on the outer wall of the second telescopic rod 72. The fourth spring 73 can further provide shock absorption for the fixed plate 1.

[0031] The connecting assembly 8 includes a fixed base 81 mounted on the top of the fixed plate. The fixed base 81 has a receiving groove 83 inside. A pull rod 82 is slidably connected to one side of the receiving groove 83. One end of the pull rod 82 is rotatably connected to one end of a connecting rod 84. The other end of the connecting rod 84 is fixedly connected to one end of a locking block 87. The locking block 87 is rotatably connected inside the receiving groove 83. A limiting sleeve 85 is installed inside the receiving groove 83. A fifth spring 86 is sleeved inside the limiting sleeve 85. One end of the fifth spring 86 is fixedly connected to one end of the pull rod 82. The locking block 87, which is rotatably connected inside the receiving groove 83, can flexibly adjust its position, thereby limiting the position of the drone support 2. The pull rod 82 and the connecting rod 84 can easily drive the locking block 87 to rotate.

[0032] The locking block 87 is L-shaped and is connected to the locking slot 21. One end of the drone bracket 2 is inserted into the top of the receiving slot 83. By setting the locking block 87 and the locking slot 21 to be connected, the drone bracket 2 can be fixed in the receiving slot 83.

[0033] The operating principle of the engineering inspection surveying device in this embodiment is as follows: When installed on a drone, by pulling the pull rod 82 in the connecting assembly 8, the pull rod 82 moves along the receiving groove 83, and the pull rod 82 pulls the fifth spring 86 to stretch. The pull rod 82 pulls the locking block 87 to rotate through the connecting rod 84. Then, the bottom of the drone bracket 2 is inserted into the receiving groove 83 along the top of the receiving groove 83. When the bottom of the drone bracket 2 is pressed against the limiting sleeve 85, the pull rod 82 is released, the fifth spring 86 resets, and the pull rod 82 resets. Under the action of the fifth spring 86, the pull rod 82 pulls the locking block 87 to rotate through the connecting rod 84. The locking block 87 rotates and engages with the locking groove 21, thereby fixing the drone bracket 2 in the fixing seat 81. This facilitates quick and easy installation on the drone and convenient disassembly and use. When the drone lands on the ground... When the buffer plate 65, the protruding post 63 and the third spring 66 are set, the support plate 5 and the fixed plate 1 are provided with primary shock absorption. When the protruding post 63 moves upward, it will squeeze the sliders 62 on both sides. The sliders 62 slide along the inner groove 61 and compress the second spring 64, thereby providing secondary shock absorption for the support plate 5 and the fixed plate 1. The support plate 5 pushes the first telescopic rod 4 to retract and compress the first spring 41, thereby providing a third shock absorption for the fixed plate 1. With the superposition of multiple shock absorption effects, the damage to the UAV body or the surveying instrument 3 can be effectively avoided when landing. At the same time, the side blocks 7 and side guard plates 71 set on both sides of the support plate 5 can provide auxiliary support for the fixed plate 1 on uneven ground, preventing the fixed plate 1 from tilting and providing protection for the surveying instrument 3. The fourth spring 73 can further provide shock absorption for the fixed plate 1.

[0034] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
