Description

Technical Field

[0001] The present invention relates to an unmanned aerial vehicle (UAV), and in particular to a support structure for an UAV. Background Art

[0002] Overhead lines on transmission lines are prone to bird droppings accumulation, which is generally difficult to remove. Currently, drones are generally used for removal, but existing obstacle removal drones have the following main shortcomings:

[0003] First, the cleaning effect is not obvious and the adjustability is poor. When cleaning bird droppings on cables, existing equipment often scrapes them off. Second, the existing cleaning structure is relatively fixed and cannot be adapted to cables of different diameters at the same time. Third, the bird droppings are hard after drying on the cable, and the existing equipment is relatively slow in cleaning. Fourth, disassembly and installation are not convenient. The clearance structures on existing obstacle removal drones are mostly fixed with bolts. Therefore, all the fixing bolts need to be loosened and removed during disassembly, which is not convenient.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a bracket structure for drones is developed in order to achieve a more practical purpose. Summary of the Invention

[0005] The present invention provides a bracket structure for an unmanned aerial vehicle (UAV). The bracket structure can be quickly installed on a support frame of the UAV, is easy to install, and can quickly and efficiently remove bird droppings on power transmission lines. At the same time, it can be adapted to use with power transmission lines of various diameters.

[0006] The technical solution of the present invention is:

[0007] A support structure for an unmanned aerial vehicle (UAV), comprising an UAV body and a support frame fixed on both sides of the bottom of the UAV body, the support structure comprising a sliding seat, the top of the sliding seat being slidably connected to the support frame, the bottom of the sliding seat being fixedly connected to a cleaning structure, the cleaning structure comprising a cleaning seat, a triangular prism-shaped cleaning protrusion being provided at the bottom center of the cleaning seat, and the head end of the cleaning protrusion being a triangular pyramid-shaped structure, the cleaning seat being provided with sliding grooves on both sides of the cleaning protrusion, and cleaning wings being slidably connected in both sliding grooves, and fixing bolts being threadedly connected to the cleaning wings.

[0008] First, the sliding seat is slidably installed on the support frame of the drone body, which is easy to disassemble and install; during use, the cleaning structure can be driven by the drone body to clean the bird droppings on the cable line. Since a triangular prism-shaped cleaning protrusion is provided at the bottom of the cleaning seat, and the head end of the cleaning protrusion has a triangular pyramid-shaped structure, when cleaning bird droppings on the cable, the bird droppings can be crushed and cleaned as the drone body flies forward, thereby achieving fast and efficient removal; at the same time, a cleaning wing is slidably connected in the sliding groove at the bottom of the cleaning seat, and a fixing bolt is threaded on the cleaning wing. Therefore, when in use, the distance between the two cleaning wings can be appropriately adjusted by sliding according to the width of the cable, and locked and fixed by the fixing bolt to achieve cleaning of cables with different diameters.

[0009] Furthermore, the two cleaning wings are symmetrically arranged in an "eight" shape on both sides of the cleaning protrusion, which makes it easier for the two cleaning wings to clean the bird droppings on both sides of the cable, making the cleaning more clean and efficient.

[0010] Furthermore, the bottom end of the cleaning wing is an inclined structure with an inclination angle of 60 degrees, so that the cleaning wing can also play a crushing role when cleaning bird droppings and other debris on the cable, thereby improving the smoothness of cleaning.

[0011] Furthermore, trapezoidal sliding protrusions are welded on both sides of the support frame, the top of the sliding seat is a concave structure, and trapezoidal sliding grooves are opened on both sides of the inner wall of the concave structure, and the sliding seat is slidably connected to the trapezoidal sliding protrusion of the support frame through the trapezoidal sliding grooves.

[0012] During installation, the trapezoidal sliding grooves on both sides of the inner wall of the concave structure of the sliding seat and the trapezoidal sliding protrusions on the left and right sides of the support frame can be slidably connected, which is convenient and fast, and easy to install and disassemble.

[0013] Furthermore, an elastic latch is fixed on the support frame, and the elastic latch includes a latch seat and a latch shaft. The latch seat is provided with a first clamping plate and a second clamping plate with circular holes, and the latch shaft passes through the first clamping plate and the second clamping plate through the circular hole. A limiting protrusion is provided at the circular hole of the second clamping plate. The latch shaft is located between the first clamping plate and the second clamping plate, and a spring is sleeved on the shaft body, and one end of the spring is fixed on the limiting protrusion, and the other end is fixed on the latch shaft. A latch hole that cooperates with the latch shaft is opened on the sliding seat.

[0014] When the sliding seat is slidably installed on the support frame of the drone body, the pin shaft is pulled upwards and the spring is in a stretched state. When the trapezoidal sliding groove of the sliding seat is completely slid and connected with the trapezoidal sliding protrusion of the support frame, the pin shaft is lowered. Due to the reset effect of the spring, the pin shaft automatically moves downwards and is inserted into the pin hole for limit fixation, making the sliding seat more firmly installed on the support frame.

[0015] Furthermore, the plug-in end of the latch shaft is of an inclined structure. When installing the sliding seat, the sliding seat directly slides along the trapezoidal sliding protrusions on both sides of the support frame through the trapezoidal sliding grooves on both sides. After it reaches the latch shaft, due to the inclined plug-in end of the latch shaft, the sliding seat continues to push forward to lift the latch shaft. Then, when it reaches the latch hole, the latch shaft automatically drops and plugs into the latch hole due to the action of the spring. The latch can be locked without pulling the latch shaft, which simplifies the installation process to a certain extent.

[0016] Furthermore, a rectangular limiting column is welded on the outer wall of the latch shaft, which can limit the latch shaft during use and prevent the latch shaft from axially rotating, which would result in the inability to lock the sliding seat.

[0017] The beneficial effects of the present invention are:

[0018] The present invention is provided with a sliding seat. First, the sliding seat and the support frame of the drone body are slidably connected and locked by an elastic pin. Since the bottom end surface of the pin shaft is an inclined structure, the pin can be locked without pulling the pin shaft when installing the sliding seat. Compared with the existing technology, the present device is more convenient and quick when installing the cleaning structure, and has higher practicality. At the same time, the cleaning structure at the bottom of the sliding seat is provided with a triangular prism-shaped cleaning protrusion, and the head end of the cleaning protrusion is a triangular pyramid-shaped structure. The sharp edges and ends of the cleaning wing are used to crush and clean the bird droppings, which can achieve fast and efficient cleaning. Moreover, the cleaning wing is slidably connected to the cleaning seat. When in use, the distance between the two cleaning wings can be appropriately adjusted by sliding according to the width of the cable, and locked and fixed by fixing bolts to achieve cleaning of cables with different diameters.

[0026] Example 1:

[0027] like Figure 1-Figure 5 As shown, the present invention provides a support structure for a drone, comprising a drone body 1 and a support frame 2 fixed on both sides of the bottom of the drone body 1, the support structure comprises a sliding seat 3, a trapezoidal sliding protrusion 201 is welded on the left and right sides of the support frame 2, the top of the sliding seat 3 is a concave structure, and a trapezoidal sliding groove 301 is opened on the left and right sides of the inner wall of the concave structure, the sliding seat 3 is slidably connected to the trapezoidal sliding protrusion 201 of the support frame 2 through the trapezoidal sliding groove 301, and the bottom of the sliding seat 3 is fixedly connected to two cleaning structures by bolts, the cleaning structure comprises a cleaning seat 4, the cleaning seat 4 is fixed to the bottom of the sliding seat 3 by bolts, a triangular prism-shaped cleaning protrusion 5 is provided at the bottom center of the cleaning seat 4, and the head end of the cleaning protrusion 5 is a triangular pyramid-shaped structure, the cleaning seat 4 is provided with sliding grooves 401 on both sides of the cleaning protrusion 5, and cleaning wings 6 are slidably connected in the two sliding grooves 401, and fixing bolts 7 are threaded on the cleaning wings 6.

[0028] First, the trapezoidal sliding grooves 301 on both sides of the concave structure inner wall of the sliding seat 3 are slidably connected with the trapezoidal sliding protrusions 201 on the left and right sides of the support frame 2, so that the sliding seat 3 is slidably installed on the support frame 2 of the drone body 1, which is convenient for disassembly and installation; during use, the cleaning structure can be driven by the drone body 1 to clean the bird droppings on the cable line. Since the cleaning protrusion 5 is provided with a triangular prism-shaped cleaning protrusion 5 at the bottom of the cleaning seat 4, and the head end of the cleaning protrusion 5 has a triangular pyramid-shaped structure, when cleaning bird droppings on the cable, the bird droppings can be crushed and cleaned as the drone body 1 flies forward, thereby achieving fast and efficient removal; at the same time, a cleaning wing 6 is slidably connected in the sliding groove 401 at the bottom of the cleaning seat 4, and a fixing bolt 7 is threadedly connected to the cleaning wing 6. Therefore, when in use, the distance between the two cleaning wings 6 can be appropriately adjusted according to the width of the cable, and locked and fixed by the fixing bolt 7 to achieve cleaning of cables with different diameters.

[0029] See also Figure 2 and Figure 5 In this embodiment, the two cleaning wings 6 are symmetrically arranged in an "eight" shape on both sides of the cleaning protrusion 5, which makes it easier for the two cleaning wings 6 to clean the bird droppings on both sides of the cable, making the cleaning more clean and efficient.

[0030] See also Figure 5 In this embodiment, the bottom end of the cleaning wing 6 is an inclined structure with an inclination angle of 60 degrees, so that the cleaning wing 6 can also play a crushing role when cleaning bird droppings on the cable, thereby improving the smoothness of cleaning.

[0031] See also Figure 4 In order to further enhance the stability of the sliding seat 3 installed on the support frame 2, an elastic latch is fixed on the support frame 2, and the elastic latch includes a latch seat 8 and a latch shaft 9. The latch seat 8 is welded to one side edge of the support frame 2 and is placed above the trapezoidal sliding protrusion 201. The latch seat 8 is provided with a first clamping plate 801 and a second clamping plate 802 with a circular hole. The latch shaft 9 passes through the first clamping plate 801 and the second clamping plate 802 through the circular hole. A limiting protrusion 803 is provided at the circular hole of the second clamping plate 802. The latch shaft 9 is located between the first clamping plate 801 and the second clamping plate 802 and is sleeved with a spring 10. One end of the spring 10 is fixed on the limiting protrusion 803, and the other end is fixed on the latch shaft 9. A latch hole that cooperates with the latch shaft 9 is opened on the sliding seat 3.

[0032] During the process of the sliding seat 3 being slidably installed on the support frame 2 of the drone body 1, the latch shaft 9 is pulled upwards and the spring 10 is in a stretched state. When the trapezoidal sliding groove 301 of the sliding seat 3 is completely slidably connected with the trapezoidal sliding protrusion 201 of the support frame 2, the latch shaft 9 is lowered. Due to the reset effect of the spring 10, the latch shaft 9 automatically moves downwards and is inserted into the latch hole for limit fixation, so that the sliding seat 3 is installed on the support frame 2 more firmly.

[0033] See also Figure 4 In order to make the insertion of the latch shaft 9 more convenient and improve the installation efficiency, in this embodiment, the plug-in end of the latch shaft 9 is an inclined structure. When installing the sliding seat 3, the sliding seat 3 directly slides and advances along the trapezoidal sliding protrusions 201 on both sides of the support frame 2 through the trapezoidal sliding grooves 301 on both sides. After being pushed to the latch shaft 9, due to the inclined structure of the plug-in end of the latch shaft 9, the sliding seat 3 continues to advance forward to lift the latch shaft 9. Then, when it reaches the latch hole position, due to the action of the spring 10, the latch shaft 9 automatically falls and is inserted into the latch hole. There is no need to pull the latch shaft 9 to complete the locking of the latch, which simplifies the installation steps to a certain extent.

[0034] See also Figure 4 In this embodiment, a rectangular limiting column 901 is welded on the outer wall of the latch shaft 9, which can limit the latch shaft 9 when in use to prevent the latch shaft 9 from axially rotating and making it impossible to lock the sliding seat 3.

[0035] The specific usage and function of this embodiment are as follows:

[0036] During installation, first, the trapezoidal sliding grooves 301 on both sides of the inner wall of the concave structure of the sliding seat 3 are slidably connected with the trapezoidal sliding protrusions 201 on the left and right sides of the support frame 2, so that the sliding seat 3 is slidably installed on the support frame 2 of the drone body 1 and locked by the elastic latch. At this time, because the bottom end surface of the latch shaft 9 is an inclined structure, it is not necessary to pull the latch shaft 9 when installing the sliding seat 3 to complete the latch locking, which simplifies the installation steps to a certain extent.

[0037] The cleaning wing 6 is provided with a tilted structure and an inclination angle of 60 degrees, so that the cleaning wing 6 can also play a role in crushing the debris of the bird droppings on the cable, thereby improving the smoothness of cleaning.
