[0046] The inventors found that in the existing technology, in order to effectively alleviate the impact of instantaneous wind caused by helicopter takeoff and landing on the surrounding environment, safety nets are often set up around the apron. The commonly used ones are movable safety nets, which require manual cooperation to operate the safety net to unfold or erect it to meet the different usage conditions of the safety net. However, the automation effect is poor and manual operation is required, which is time-consuming and labor-intensive.

[0047] In order to solve the above problems, the inventors have proposed a safety net device for aprons after research and development. The device can automatically switch between different usage states of the safety net, is easy to use, and has a high degree of automation.

[0048] Example

[0049] See Figure 1 and Figure 2 An embodiment of the present application provides a safety net device for a helipad, comprising a first support base 1, a second support base 2, a safety net assembly 3, a drive assembly 4, a chute 5, and a sliding assembly 6. The first support base 1 and the second support base 2 are connected to the first side and the second side of the helipad, respectively. The chute 5 is arranged horizontally along the helipad and is slidably connected to the sliding assembly 6. The safety net assembly 3 is slidably connected to the sliding assembly 6. The safety net assembly 3 can be erected between the first support base 1 and the second support base 2 in a horizontal position; the safety net assembly 3 can be flipped to an upright position using the first support base 1 or the second support base 2 as a fulcrum. The first support base 1 and the second support base 2 provide stable support points for the safety net assembly 3. Their layout and spacing should ensure that the safety net assembly 3 remains stable in both the horizontal and upright positions. The drive assembly 4 is connected to the sliding assembly 6 and is responsible for providing power to drive the sliding assembly 6 to move, thereby driving the safety net assembly 3 to rotate to a horizontal position or an upright position.

[0050] During helicopter takeoff and landing, especially in strong winds, the driving assembly 4 drives the sliding assembly 6 to move, thereby causing the safety net assembly 3 to flip to an upright position with the first support base 1 or the second support base 2 as the fulcrum. The raised safety net assembly 3 can effectively block strong winds, preventing strong winds from damaging buildings, equipment, or personnel around the helipad, effectively providing good safety protection for the helipad's surrounding environment. During this process, the safety net assembly 3 is raised through the coordinated action of the driving assembly 4, the chute 5, and the sliding assembly 6, eliminating the need for manual lifting of the safety net assembly 3. This not only improves work efficiency and eases use, but also ensures operational safety and avoids risks that may be caused by improper manual operation.

[0051] Because the safety net assembly 3 can be flipped using the first support base 1 and the second support base 2 as fulcrums, the safety net assembly 3 can be selectively raised on the side with stronger wind force according to actual conditions, thereby achieving precise protection for the environment on both sides of the apron. Specifically, the staff detects the wind force in real time. For example, if the staff accurately detects that the wind force on the first side of the apron is strong and exceeds the preset safety threshold, the safety net assembly 3 is raised using the first support base 1 as the fulcrum. The safety net assembly 3 protects the surrounding environment on the first side of the apron, ensuring maximum protection. The safety net device of this embodiment can selectively raise the safety net assembly 3 according to actual wind force conditions, achieving precise protection for the environment around the apron, and has high flexibility and ease of operation.

[0052] In one embodiment, see Figure 1 The drive assembly 4 includes a first connecting rod 41, a second connecting rod 42, and a motor 43. The first connecting rod 41 is connected to the output shaft of the motor 43, and the two ends of the second connecting rod 42 are respectively connected to the first connecting rod 41 and the sliding assembly 6. The motor 43 serves as a power source, and the output shaft of the motor 43 is responsible for providing rotational power. When the motor 43 is started, the first connecting rod 41 will perform a circular motion around the output shaft of the motor 43. The circular motion of the first connecting rod 41 drives the rotation of the second connecting rod 42, thereby driving the sliding assembly 6 to move along the slide 5.

[0053] When using, refer to Figure 1At this time, the safety net assembly 3 is in a horizontal state, and the sliding assembly 6 is in the middle of the chute 5. When the safety net assembly 3 needs to be raised with the first support base 1, the motor 43 is started, the motor 43 rotates counterclockwise, and the first connecting rod 41 rotates counterclockwise accordingly. The first connecting rod 41 drives the second connecting rod 42 to rotate, and the rotation of the second connecting rod 42 drives the sliding assembly 6 to move leftward along the chute 5. During this process, the safety net assembly 3 flips to an upright state with the first support base 1 as a fulcrum, and the motor 43 is turned off. When the safety net assembly 3 needs to be switched from the upright state to the horizontal state, the motor 43 is started again, the motor 43 rotates clockwise, the first connecting rod 41 rotates clockwise with the motor 43, and the second connecting rod 42 rotates with the first connecting rod 41. Then, the rotation of the second connecting rod 42 drives the sliding assembly 6 to move rightward along the chute 5 until it reaches the middle position of the chute 5. At this time, the safety net assembly 3 returns to the horizontal state, and the motor 43 is turned off.

[0054] When the safety net assembly 3 needs to be raised with the second support base 2 as the fulcrum, the motor 43 is started, the motor 43 rotates clockwise, the first connecting rod 41 rotates clockwise with the motor 43, and the second connecting rod 42 rotates with the first connecting rod 41, and then the rotation of the second connecting rod 42 drives the sliding assembly 6 to move to the right along the slide groove 5. In this process, the safety net assembly 3 is flipped to the position as shown in the figure with the second support base 2 as the fulcrum. Figure 2 When the safety net assembly 3 needs to be switched from the upright state to the horizontal state, the motor 43 is started again, the motor 43 rotates counterclockwise, the first connecting rod 41 rotates counterclockwise along with the motor 43, and the second connecting rod 42 rotates along with the first connecting rod 41. Then, the rotation of the second connecting rod 42 drives the sliding assembly 6 to move leftward along the chute 5 until it reaches the middle position of the chute 5. At this time, the safety net assembly 3 returns to the horizontal state and the motor 43 is turned off.

[0055] In this embodiment, the entire drive assembly 4 is compact and occupies little space, making it easy to install and use in confined spaces such as helipads. By cleverly integrating the motor 43, first connecting rod 41, second connecting rod 42, and sliding assembly 6, the safety net assembly 3 smoothly transitions between horizontal and upright positions, enabling precise control of the state of the safety net assembly 3. Furthermore, by changing the rotation direction of the motor 43, the safety net assembly 3 can be raised toward the side of the helipad with higher wind speeds, allowing for flexible adjustments based on actual conditions, achieving precise protection for the surrounding environment and demonstrating strong adaptability.

[0056] In one embodiment, see Figure 1The safety net device also includes a wind-sensing intelligent module (not shown) and a control module (not shown). The control module is connected to the motor 43 and is used to control the rotation direction of the motor 43. The wind-sensing intelligent module is connected to the control module. The wind-sensing intelligent module can sense the wind level on the first side and the second side of the apron respectively. This sensing data is collected in real time by the wind-sensing intelligent module and converted into electrical signals for transmission. These electrical signals are received as command signals by the control module, and the control module controls the rotation direction of the motor 43 according to the content corresponding to the command information.

[0057] When the wind force sensing intelligent module senses that the wind force level on the first side of the apron has reached a preset threshold value (the preset threshold value is set to 6-8 instantaneous wind force), and the wind force level on the second side of the apron has not reached the preset threshold value, a first instruction is sent to the control module to control the motor 43 to move in a first preset direction (i.e., Figure 1 ) to rotate the safety net assembly 3 with the first support base 1 as the fulcrum; when the wind force sensing intelligent module senses that the wind force level on the second side of the apron has reached a preset threshold value, and the sensed wind force level on the first side of the apron has not reached the preset threshold value, a second instruction is sent to the control module to control the motor 43 to rotate in the second preset direction (i.e., as shown in FIG. Figure 1 ) to rotate the safety net assembly 3 with the second support base 2 as a fulcrum.

[0058] In this embodiment, the wind-sensing intelligent module can monitor and accurately determine wind levels on both sides of the apron in real time, ensuring timely response in strong wind conditions. Based on the wind-sensing intelligent module's instructions, the control module rapidly adjusts the rotation direction of motor 43, enabling rapid flipping of the safety net assembly 3. This effectively blocks the potential threat of strong winds to the apron environment, enhancing the safety and reliability of the device. Furthermore, the control module's control of motor 43 enables automatic flipping and adjustment of the safety net assembly 3, eliminating the need for manual intervention, reducing labor costs and operational complexity, and achieving a high level of automation.

[0059] In one embodiment, see Figure 1 The sliding assembly 6 includes a sliding block 61 and a limiting groove 62 connected to the sliding block 61. The sliding block 61 is connected to the second connecting rod 42. The sliding block 61 is the main component of the sliding assembly 6 and is responsible for moving within the sliding groove 5 to adjust the position of the safety net assembly 3. The limiting groove 62 is vertically arranged and slidably connected to the safety net assembly 3, allowing the safety net assembly 3 to rotate smoothly under the guidance of the limiting groove 62. At the same time, the limiting groove 62 can limit the range of movement of the safety net assembly 3, ensuring that it does not exceed the predetermined trajectory during rotation.

[0060] During operation, motor 43 drives first connecting rod 41 to rotate, and second connecting rod 42 rotates with it. The rotation of second connecting rod 42 drives sliding block 61 to slide within chute 5. Sliding block 61 moves with limiting groove 62, and the movement of limiting groove 62 forces safety net assembly 3 to rotate around first support base 1 or second support base 2. The design of sliding assembly 6 provides a stable and flexible flipping mechanism for the safety net device, ensuring the stability and reliability of safety net assembly 3 in different states.

[0061] In one embodiment, see Figure 1 and Figure 2 The safety net assembly 3 comprises a main body 31 and support arms 32. The main body 31 effectively blocks strong winds, cushioning their impact on the apron and surrounding environment, providing a necessary protective barrier. The support arms 32 surround and connect to the outside of the main body 31, supporting and securing the main body 31. Both the main body 31 and the support arms 32 are made of high-strength alloy materials, including iron, aluminum alloy, or other materials. This ensures greater strength and a longer service life for the main body 31 and support arms 32.

[0062] In one embodiment, see Figure 1 The safety net assembly 3 also includes a connecting rod 34 and a sliding key 35. The ends of the connecting rod 34 are connected to the support arm 32 and the sliding key 35, respectively. The sliding key 35 is accommodated in a retaining groove 62 and can slide along the retaining groove 62. When the sliding block 61 slides within the slide groove 5, the retaining groove 62 moves with the sliding block 61. The movement of the retaining groove 62 forces the sliding key 35 to slide along the retaining groove 62, thereby driving the support arm 32 and the safety net body 31 to rotate together through the connecting rod 34. The design of the sliding assembly 6 enables the safety net assembly 3 to easily transition between a horizontal and an upright position, and is simple and quick to operate.

[0063] In one embodiment, see Figure 1 and Figure 2The safety net assembly 3 also includes a support shaft 33. The first and second side surfaces of the support arm 32 are both connected to the support shaft 33, and the support shaft 33 is perpendicular to the length direction of the slide 5, wherein the first and second side surfaces are arranged opposite to each other. The first support base 1 and the second support base 2 are respectively provided with support grooves (not shown in the figure) corresponding to the support shaft 33. When the support arm 32 rotates with the first support base 1 and the second support base 2 as fulcrums, the support shaft 33 provided on the support arm 32 can be engaged with the corresponding support groove. The support groove can limit the support shaft 33, providing a solid fulcrum for the support arm 32 and the safety net body 31, ensuring the stability of the support arm 32 and the safety net body 31 during rotation, preventing safety hazards caused by shaking or offset, and improving the reliability and safety of the entire safety net device. Here, the shape and size of the support groove match the support shaft 33 to ensure that the support shaft 33 can be smoothly engaged in the support groove and remain stable during rotation.

[0064] In one embodiment, see Figure 1 The safety net assembly 3 also includes an elastic member (not shown in the figure) arranged on the first side surface and the second side surface. When the safety net body 31 and the support arm 32 rotate from a horizontal state to an upright state, the elastic member can abut against the ground of the apron. The elastic member can buffer the rotation of the safety net body 31 and the support arm 32. The buffering effect of the elastic member can reduce the impact force when the safety net assembly 3 rotates, thereby improving the safety and reliability of the entire safety net device.

The present disclosure is not limited to the precise structure described above and illustrated in the accompanying drawings, and various modifications and variations may be made without departing from its scope.
