Technical Field

[0001] This utility model relates to the field of helipad technology, specifically a security drone helipad. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft controlled by radio remote control equipment and onboard program control devices, or operated autonomously by an onboard computer, either completely or intermittently. With the rapid development of UAV technology, UAVs have been widely used in many fields, such as aerial photography, agricultural plant protection, and logistics distribution. However, the landing process of UAVs has always required a secure UAV landing pad.

[0003] Regarding the aforementioned technologies, the applicant believes that when a security drone is operating on a landing pad, if a crosswind occurs during landing, the crosswind will generate a continuous lateral thrust on the drone. This thrust will disrupt the drone's original landing attitude balance, causing the fuselage to deviate in heading angle, shift laterally, or even cause airflow disturbances to the propellers, exacerbating the fuselage's swaying and increasing the probability of the drone hitting the edge of the landing pad, thereby causing damage to the drone. Utility Model Content

[0004] The purpose of this invention is to provide a landing pad for security drones, in order to solve the problem mentioned in the background art that when a drone lands in the presence of crosswinds, the crosswinds will generate a continuous lateral thrust on the drone. This thrust will disrupt the drone's original landing attitude balance, causing the fuselage to deviate in heading angle, shift laterally, and even cause the propeller airflow disturbance to aggravate the fuselage shaking, increasing the probability of the drone hitting the edge of the landing pad, thereby causing damage to the drone.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a security drone landing pad, comprising a fixed base and a protective mechanism.

Then, through the transmission of the driven bevel gear, transmission rod, first bevel gear and second bevel gear, the lead screw can be driven to rotate, which in turn drives the movable rod to move upward. Through the transmission of the connecting rod, the windproof cloth can be moved out of the accessory box, thereby forming a surrounding windproof barrier around the landing platform to minimize the impact of crosswinds on the take-off and landing of the drone.

[0007] Preferably, the top of the fixed base is provided with an accessory box, the interior of which is a hollow structure.

[0008] By adopting the above technical solution, the windproof cloth can be stored conveniently.

[0009] Preferably, a counterweight fixing block is provided at the bottom of the accessory box, and the top of the counterweight fixing block is connected to the windproof cloth.

[0010] By adopting the above technical solution, the bottom of the windproof cloth can be easily fixed.

[0011] Preferably, the movable rods are provided in two sets, and the movable rods are symmetrically distributed about the center point inside the fixed base.

[0012] By adopting the above technical solution, the stability of the connecting rod when moving up and down can be improved.

[0013] Preferably, the windproof fabric is made of PVC-coated fiberglass cloth.

[0014] By adopting the above technical solution, external wind force can be effectively blocked.

[0015] Preferably, the fixed base has support seats at both ends of its inner bottom, and the transmission rod passes through the interior of the support seats.

[0017] Preferably, an access door is hinged to the lower side of one side of the fixed base, and a handle is provided on the outer side of the access door.

[0018] By adopting the above technical solution, the internal components of the fixed base can be easily inspected and repaired by opening the inspection door.

[0019] Preferably, the middle part of the top of the fixed base is provided with a stopping platform, which is circular.

[0020] By adopting the above technical solution, it is possible to facilitate the landing of drones.

[0021] Compared with the prior art, the beneficial effects of this utility model are: Equipped with a protective mechanism, lead screw, drive motor, and fixed base, the drive motor rotates the active bevel gear, which in turn rotates the lead screw via the driven bevel gear, transmission rod, first bevel gear, and second bevel gear. This causes the movable rod to move upwards, and through the connecting rod, the windproof cloth can be removed from the accessory box, thus forming a surrounding windproof barrier around the landing platform to minimize the impact of crosswinds on the drone's takeoff and landing.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1 Please see Figures 1 to 4This embodiment provides a technical solution: a security drone landing pad, including a fixed base 2 and a protective mechanism 1. The protective mechanism 1 is disposed inside the fixed base 2 and includes a drive motor 113 disposed below the fixed base 2. The drive motor 113 operates based on the principle of electromagnetic induction. When three-phase alternating current is applied to the stator windings, a rotating magnetic field is generated in the stator core. Its rotational speed is determined by the power supply frequency and the number of pole pairs of the motor. The rotor conductors cut magnetic lines of force in the rotating magnetic field to generate an induced current. The interaction between the current and the magnetic field generates an electromagnetic torque, driving the rotor to rotate. When selecting the appropriate model, it should be selected according to actual needs. The components required in the drive motor 113 are all existing technologies and will not be described in detail below.

[0026] The driving bevel gear 115 is fixedly connected to the output end of the drive motor 113, and the driven bevel gear 114 is meshed at both ends of the driving bevel gear 115. The transmission rod 109 is fixedly connected to the end of the driven bevel gear 114 away from the driving bevel gear 115. The support base 108 is fixedly connected to both ends of the bottom inside the fixed base 2. The transmission rod 109 passes through the interior of the support base 108, which can facilitate the support of the transmission rod 109.

[0027] The first bevel gear 107 is fixedly connected to the end of the transmission rod 109 away from the driven bevel gear 114. The second bevel gear 105 is meshed at the top of the first bevel gear 107. The lead screw 106 passes through the interior of the second bevel gear 105. The slider 104 is meshed on the outside of the lead screw 106. The movable rod 103 is fixedly connected to the top of the slider 104. There are two sets of movable rods 103, which are symmetrically distributed about the center point inside the fixed base 2.

[0028] The connecting block 110 is fixedly connected to one end of the movable rod 103 near the drive motor 113. The connecting rod 102 is fixedly connected to the bottom end of the connecting block 110. The windproof cloth 111 is fixedly connected to the bottom end of the connecting rod 102. The accessory box 101 is fixedly connected to the top end of the fixed base 2. The interior of the accessory box 101 is set as a hollow structure. The counterweight fixing block 112 is fixedly connected to the bottom end of the interior of the accessory box 101. The top end of the counterweight fixing block 112 is connected to the windproof cloth 111. The windproof cloth 111 is made of PVC coated fiberglass cloth.

[0029] The effect achieved by the entire embodiment is as follows: the drive motor 113 is started by the control switch, and the output shaft of the drive motor 113 drives the active bevel gear 115 to rotate; the active bevel gear 115 meshes with the driven bevel gear 114 to transmit power to the horizontally arranged stainless steel transmission rod 109, and through the vertical meshing of the first bevel gear 107 and the second bevel gear 105, the lead screw 106 is driven to rotate synchronously. The slider 104 sleeved on the outside of the lead screw 106 rises smoothly in the vertical direction under the transmission action of the lead screw 106, which can drive the movable rod 103 to move accordingly; the top of the movable rod 103 is connected to the connecting rod 102 through the connecting block 110, and the other end of the connecting rod 102 is fixedly connected to the windproof cloth 111 in the accessory box 101. As the movable pole 103 rises, the connecting pole 102 simultaneously pulls the windproof cloth 111 out of the accessory box 101, ultimately forming a surrounding windproof barrier around the landing platform 4. This effectively weakens the crosswind force, significantly reduces the lateral thrust of the crosswind on the landing drone, reduces the deviation of the fuselage heading angle and lateral displacement, helps the drone accurately align with the center positioning area of ​​the circular flat plate, and reduces the difficulty of landing and the risk of equipment collision.

[0030] Example 2 The maintenance door 3 is hinged to the lower side of one side of the fixed base 2. A handle is provided on the outer side of the maintenance door 3. The parking platform 4 is fixedly connected to the middle part of the top of the fixed base 2. The parking platform 4 is circular.

[0031] The effect achieved by the entire second embodiment is that by opening the inspection door 3, the accessories inside the fixed base 2 can be easily inspected and repaired.

[0032] Working principle: The drive motor 113 is started by the control switch. The output shaft of the drive motor 113 drives the active bevel gear 115 to rotate. The active bevel gear 115 meshes with the driven bevel gear 114 to transmit power to the horizontally arranged stainless steel transmission rod 109. Through the vertical meshing of the first bevel gear 107 and the second bevel gear 105, the lead screw 106 is driven to rotate synchronously. The slider 104 sleeved on the outside of the lead screw 106 rises smoothly in the vertical direction under the transmission action of the lead screw 106, which can drive the movable rod 103 to move accordingly. The top of the movable rod 103 is connected to the connecting rod 102 through the connecting block 110. The other end of the connecting rod 102 is fixedly connected to the windproof cloth 111 in the accessory box 101. As the movable pole 103 rises, the connecting pole 102 simultaneously pulls the windproof cloth 111 out of the accessory box 101, ultimately forming a surrounding windproof barrier around the landing platform 4. This effectively weakens the crosswind force, significantly reduces the lateral thrust of the crosswind on the landing drone, reduces the deviation of the fuselage heading angle and lateral displacement, helps the drone accurately align with the center positioning area of ​​the circular flat plate, and reduces the difficulty of landing and the risk of equipment collision.
