DETAILED DESCRIPTION

[0023] 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.

[0024] like Figure 1 and Figure 2 As shown, the utility model provides a technical solution: a UAV positioning device for crane inspection, comprising a base 1, a support platform 7 is fixedly connected to the upper surface of the base 1, the support platform 7 is a plate-shaped platform, the upper surface of which is used to place the UAV, and the lower surface is provided with a pillar 71, the bottom surface of the pillar 71 is fixedly connected to the upper surface of the base 1, so as to realize the fixed connection between the support platform 7 and the base 1; preferably, two parallel first side panels 8 and two parallel second side panels 15 are fixedly connected to the upper surface of the support platform 7, and the four side panels form a accommodating space, and the UAV falls into the accommodating space; preferably, there are four pillars, which are evenly distributed along the circumference of the lower surface of the support platform 7, which can not only be used to fix the support platform 7 to the base 1, but also can leave space between the lower surface of the support platform 7 and the upper surface of the base 1 for installing the driving structure of the protective component to be described in detail below, so that the overall structure is compact and space-saving.

[0025] In this embodiment, in order to make the positioning of the drone more accurate, Figure 1-3As shown, the first side plate 8 and the second side plate 15 are both fixed at the edge of the upper surface of the support platform 7 to maximize the range of the accommodating space, and the center of the accommodating space is the apron 18; the surface of the first side plate 8 facing the interior of the accommodating space is installed with an electric push rod 9, and the output end of the electric push rod 9 is fixedly connected to the first push plate 10, the first push plate 10 is in the shape of a rectangular long strip, and one end of the first push plate 10 is fixedly connected to a connecting plate 11, the first push plate 10 and the connecting plate 11 form an "L" shape, and the surface of the connecting plate 11 has a circular through hole for the sliding rod 12 to pass through, and the sliding rod 12 passes through the circular through hole , and can slide along the axis of the circular through hole. One end of the sliding rod 12 is fixedly connected to the second push plate 13, and the other end is welded and fixed with a ball 14. A limiting groove 17 for the ball 14 to slide is provided on the surface of the second side plate 15 facing the accommodating space. The ball 14 slides in the limiting groove 17, and the sliding direction is consistent with the movement direction of the output end of the electric push rod 9 on the corresponding side; a protrusion 16 is also provided on the surface of the second side plate 15 facing the accommodating space, and its cross-sectional shape is trapezoidal, and the protrusion direction is also toward the accommodating space. The limiting groove 17 extends to the surface of the protrusion 16 facing the apron 18.

[0026] To further protect the drone after landing, Figure 4 As shown, a protective structure is provided on the upper surface of the base 1 to keep the drone landing on the apron 18 in a closed state, such as Figure 1 As shown, the protective structure includes: a protective shell 5 is slidably connected to the upper surface of the base 1, and there are two protective shells 5, which are respectively located on the left and right sides of the support platform 7. When the drone needs to be used, the two protective shells 5 move away from each other to form a space for the drone to take off. After the drone lands, the two protective shells 5 move toward each other until they are buckled to form a sealed space, which plays a protective role for the drone. Preferably, a guide bar 2 is fixedly connected to the upper surface of the base 1. The guide bar 2 is two and is respectively arranged on the left and right sides of the support platform 7. A slide groove that cooperates with the guide bar 2 is arranged at the bottom of the protective shell 5, and the protective shell 5 slides along the length direction of the guide bar 2. A gear 4 is arranged on the upper surface of the base 1. The gear 4 is located in the space formed between the four pillars of the support platform 7. The gear 4 is driven by the motor 3. Racks 6 meshing with the gear 4 are fixedly connected to the opposite surfaces of the two protective shells 5. The two racks 6 are arranged in parallel and move towards each other without intersecting.

[0027] The output end of the motor 3 passes through the upper surface of the base 1 and is fixedly connected to the gear 4. The outer diameter of the gear 4 is matched with the outer diameter of the rack 6. The gear 4 is meshed and connected with the rack 6. The rack 6 is located on both sides of the outer periphery of the gear 4. The gear 4 is rotated by driving the motor 3. The rotation of the gear 4 will drive the racks 6 on both sides to move left and right. Because the racks 6 are located on both sides of the gear 4, the rotation of the gear 4 will drive the racks 6 on both sides to move synchronously toward each other, further making the protective shell 5 slide relative to the guide bar 2, thereby realizing the opening and closing of the protective shell 5. An inclined surface is set on the top of the protective shell 5 to avoid water accumulation. The inner diameter of the limit groove 17 is matched with the outer diameter of the ball 14, and the ball 14 is slidably connected to the inside of the limit groove 17. When the UAV lands on the support platform 7, the electric push rod 9 is driven to push the first push plate 10 to move toward the apron 18 until the first push plates 10 on both sides push the UAV to the apron 18c at the center position. During the movement of the first push plate 10, the connecting plate 11 connected to one end thereof drives the slide bar 12 to move synchronously, so that the ball 14 slides inside the limit groove 17 until the ball 14 slides to the limit groove 17 on the surface of the protrusion 16. Because the protruding direction of the protrusion 16 is toward the accommodating space, when the ball 14 slides to the position of the limit groove 17 on the surface of the protrusion 16, it gradually pushes the two relatively arranged second push plates 13 connected to the slide bar 12 to move toward each other, and pushes the UAV to the target area. Through the push of the first push plate 10 and the second push plate 13, the UAV is determined at the apron 18, and the precise positioning of the landing of the UAV is achieved.

[0028] Working principle: When the UAV lands in the accommodation space formed by the first side plate 8 and the second side plate 15, the electric push rod 9 is started, and the electric push rod 9 drives the corresponding first push plates 10 to move toward each other, so that the first push plates 10 move until the UAV is pushed to the target position, and the UAV can be clamped and fixed on the left and right sides by the first push plates 10 on the left and right sides. During the movement of the first push plates 10, the connecting plate 11 is driven to move synchronously, so that the ball 14 slides inside the limit groove 17 until the ball 14 slides to the limit groove 17 on the surface of the protrusion 16. Under the action of the protrusion 16, the push slide rod 12 and the second push plate 13 on the opposite side move toward each other, further clamping and fixing the front and back of the UAV, thereby realizing the precise positioning of the UAV and facilitating the automatic battery replacement interaction of the UAV; when the UAV is landed, the motor 3 is driven to drive the gear 4 to rotate, and at the same time, the rack 6 meshing with it moves toward each other, thereby driving the protective shells 5 on both sides to approach and fit together to form a closed space, thereby wrapping the support platform 7 as a whole inside, thereby improving the protection of the UAV.
