[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides, for example Figure 1 - Figure 6 The foldable safety net shown includes a base 1, a collection groove at the upper end of the base 1, mounting brackets 2 fixedly connected to both sides of the base 1, a first sliding groove 3 on the outer side of the mounting bracket 2, a folding mechanism 4 installed on the inner side of the first sliding groove 3, the folding mechanism 4 including a slider 46, and a cleaning mechanism 5 installed on one side of the slider 46.

[0024] In this embodiment, the folding mechanism 4 includes a first fixing block 41 slidably connected to the inner side of the first slide groove 3. A threaded rod 42 is threadedly connected to the inner side of the first fixing block 41. An mounting block 43 is rotatably connected to the upper end of the threaded rod 42. The front end of the mounting block 43 is fixedly connected to the mounting frame 2. A motor 44 is mounted on the upper end of the mounting block 43. The output shaft of the motor 44 is fixedly connected to the threaded rod 42.

[0025] Specifically, the first fixed block 41 is slidably connected to the inner side of the first slide groove 3. The rotational motion is converted into linear motion through the threaded rod 42. The threaded rod 42 is threadedly engaged with the first fixed block 41 and is driven to rotate by the motor 44, transmitting power to the slide plate 45. The mounting block 43 is fixed to the front end of the mounting frame 2, supporting the threaded rod 42 and constraining it to rotate only around the axis. The motor 44 provides the power source, and the output shaft directly drives the threaded rod 42 to rotate, controlling the lifting and lowering of the slide plate 45.

[0026] In this embodiment, a sliding plate 45 is fixedly connected to the front end of the first fixing block 41, and sliders 46 are fixedly connected to both sides of the sliding plate 45. The two sets of sliders 46 are slidably connected to the inner side of the mounting frame 2. Multiple sets of fan-shaped slide grooves 47 are opened on the inner side of the sliding plate 45. A first fixing shaft 48 is slidably connected to the inner side of each fan-shaped slide groove 47. A movable plate 49 is fixedly connected to the front end of the first fixing shaft 48. Two sets of symmetrical fixing rods 410 are slidably connected to the inner side of the movable plate 49. Both ends of the two sets of fixing rods 410 are fixedly connected to the mounting frame 2.

[0027] Specifically, the front end of the slide plate 45 is fixed to the first fixed block 41, and the two sides are slidably connected to the mounting frame 2 through the sliders 46 to transmit the motor driving force. The sliders 46 restrict the lateral displacement of the slide plate 45 to ensure that it slides vertically along the first slide groove 3. The fan-shaped slide groove 47 is opened on the inner side of the slide plate 45. The sliding trajectory of the first fixed shaft 48 controls the unfolding angle of the moving plate 49. The first fixed shaft 48 connects the fan-shaped slide groove 47 and the moving plate 49, converting the linear motion of the slide plate 45 into the fan-shaped unfolding of the moving plate 49. The moving plate 49 slides along the fixed rod 410. Through multiple sets of linkages, the synchronous unfolding and retraction of the main body of the barrier net 7 is achieved. The two ends of the fixed rod 410 are fixed to the mounting frame 2 as guide rails for the sliding of the moving plate 49 to ensure the stability of the unfolding process.

[0028] In this embodiment, the lower end of the movable plate 49 is rotatably connected to a second fixed shaft 6, the front end of the second fixed shaft 6 is fixedly connected to a barrier body 7, the lower end of the barrier body 7 is rotatably connected to a third fixed shaft 8, the front end of the third fixed shaft 8 is fixedly connected to a fixed plate 9, and the lower end of the fixed plate 9 is fixedly connected to the inner side of the base 1.

[0029] Specifically, the second fixed shaft 6 connects the moving plate 49 to the main body of the barrier net 7, transmitting the unfolding / retracting power and allowing the main body of the barrier net 7 to rotate around the axis. The main body of the barrier net 7 is composed of a flexible net and a rigid frame, forming a protective curved surface through fan-shaped unfolding. The third fixed shaft 8 is its unfolding fulcrum. The third fixed shaft 8 is fixed to the lower end of the main body of the barrier net 7 and is rotatably connected to the fixed plate 9, constraining the unfolding trajectory of the barrier net to a fan shape. The lower end of the fixed plate 9 is fixed to the inner side of the base 1, providing stable support for the third fixed shaft 8 and resisting the torsional torque during unfolding.

[0030] In this embodiment, the cleaning mechanism 5 includes a second fixing block 51. One side of the second fixing block 51 is fixedly connected to one of the two sets of sliders 46. A first sliding rod 52 is fixedly connected to the inner side of the second fixing block 51. A U-shaped tube 53 is slidably connected to the outer side of the first sliding rod 52. The outer side of the U-shaped tube 53 is fixedly connected to the mounting bracket 2. A second sliding rod 54 is slidably connected to the other end of the U-shaped tube 53.

[0031] Specifically, the second fixing block 51 is fixed to one side of the slider 46 and moves up and down with the slide plate 45, squeezing the lubricating oil in the U-shaped tube 53. The first slide rod 52 connects the second fixing block 51 and the U-shaped tube 53, converting the linear motion of the slide plate 45 into hydraulic pressure. The U-shaped tube 53 is filled with lubricating oil, and the pressure generated by the squeezing of the second fixing block 51 drives the second slide rod 54 to rise and fall. The second slide rod 54 is pushed up by hydraulic pressure and returns to its original position under gravity, driving the sweeping rod 55 to complete bidirectional cleaning.

[0032] In this embodiment, a sweeping rod 55 is fixedly connected to the upper end of the second slide rod 54, and a brush 56 is fixedly connected to the rear end of the sweeping rod 55. The sweeping rod 55 passes through the mounting bracket 2.

[0033] Specifically, the sweeping rod 55 passes through the mounting bracket 2 and is fixed to the upper end of the second slide rod 54, converting the hydraulic drive into vertical reciprocating motion. The brush 56 is fixed to the rear end of the sweeping rod 55 and scrapes the surface of the main body of the barrier net 7 during the up and down stroke to remove accumulated dust.

[0034] Working principle: When the device is in use, the motor 44 on the mounting block 43 is started. The output shaft of the motor 44 drives the threaded rod 42 to rotate. The threaded rod 42 drives the slide plate 45 to slide along the first slide groove 3 through the first fixed block 41. The slider 46 restricts the lateral displacement of the slide plate 45. When the slide plate 45 moves upward, the first fixed shaft 48 slides along the fan-shaped slide groove 47, pushing multiple sets of moving plates 49 to unfold outward along the fixed rod 410. The moving plates 49 pull the main body of the barrier net 7 through the second fixed shaft 6. Under the constraint of the third fixed shaft 8, the main body of the barrier net 7 unfolds in a fan shape with the third fixed shaft 8 as the fulcrum, forming a fence. When the slide plate 45 moves downward... When the device moves, the first fixed shaft 48 slides in the opposite direction along the fan-shaped slide groove 47, and the traction moving plate 49 retracts inward along the fixed rod 410. Then, the second fixed shaft 6 pulls the main body of the netting 7 to fold and reset. When the sliding plate 45 moves down, the slider 46 drives the second fixed block 51 to move down, squeezing the lubricating oil in the U-shaped tube 53 to generate pressure, pushing the second sliding rod 54 to drive the sweeping rod 55 to move up. When the sliding plate 45 moves up, the second fixed block 51 moves up accordingly, the pressure in the U-shaped tube 53 is released, and the sweeping rod 55 moves down under the action of gravity. The sweeping rod 55 scrapes up and down on the surface of the main body of the netting 7 through the brush 56, and the dust falls into the collection groove of the base 1.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
