[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Example 1: Figure 1-Figure 4 As shown, the utility model provides a technical solution: a flexible protective net, including a base plate 1, a first winding drum 6 is fastened to one side of the top of the base plate 1, a second winding drum 5 is slidably connected to the other side of the top of the base plate 1, the bottom end of the second winding drum 5 is fastened to a moving block, a screw rod 9 is inserted and connected to the surface of one side of the moving block, one end of the screw rod 9 is connected to a screw motor 4, both sides of the bottom end of the base plate 1 are fastened to limiting blocks 2, the bottom end of the limiting block 2 is fastened to a fixed shaft 3, and the upper and lower ends of the first winding drum 6 and the second winding drum 5 are fastened to limiting circular blocks 12.

[0024] In this embodiment, the base plate 1 is provided to facilitate the connection of subsequent equipment, and then under the action of the limit block 2, the fixed shaft 3 can be installed at the bottom end of the base plate 1. By using the fixed shaft 3, the equipment can be fixed on the surface of the foundation, thereby improving the stability of the equipment. Then, the protective net 7 can be stored on the first winding drum 6 and the second winding drum 5, and the screw motor 4 can be used to drive the screw 9 to operate. During the operation of the screw 9, the moving block can be driven to move. Through the movement of the moving block, the second winding drum 5 can be driven to move synchronously, thereby stretching the protective net 7.

[0025] Example 2: Figure 1-Figure 4As shown, a rotating shaft 11 is rotatably connected in the middle of the surface of the limiting circular block 12, a winding roller 10 is inserted and connected to the circumferential side of the rotating circular shaft 11, a protective net 7 is connected to one side of the winding roller 10, a first clamping block 15 is provided at the bottom end of the rotating circular shaft 11, both sides of the first clamping block 15 are clamped and connected to the second clamping block 17, one side of the second clamping block 17 is fastened with a cross plate 14, a connecting rod 16 is inserted and connected in the middle of the surface of the cross plate 14, the bottom end of the connecting rod 16 is fastened with a mounting block 13, the bottom end of the mounting block 13 is connected to the surface of the limiting circular block 12, a rotating motor 8 is connected to the top end of the rotating circular shaft 11, and the first winding drum 6 and the second winding drum 5 are symmetrical to each other.

[0026] In this embodiment, the limiting round block 12 is provided to facilitate the installation of the winding roller 10 and the rotating circular shaft 11, and prevent the winding roller 10 and the rotating circular shaft 11 from offsetting during use, resulting in the inability to extend the protective net 7. The rotating motor 8 can drive the rotating circular shaft 11 to rotate. During the rotation of the rotating circular shaft 11, the winding roller 10 can be driven to rotate synchronously, so that the protective net 7 can fall off from the peripheral side of the winding roller 10, which is convenient for subsequent installation operations. Afterwards, under the action of the installation block 13, the first clamping block 15 and the second clamping block 17 can be connected together. By using the cross plate 14 and the connecting rod 16, the second clamping block 17 can be engaged on one side of the first clamping block 15. Through the cooperation of the first clamping block 15 and the second clamping block 17, the rotating circular shaft 11 can be prevented from reversing during rotation, causing the protective net 7 to become knotted, causing the protective net 7 to be damaged and affecting subsequent use.

[0027] The working principle of this embodiment is as follows: when in use, first take the device to a preset position, then use the fixed shaft 3 to fix the device on the surface of the foundation, which improves the stability of the device, then the first winding drum 6 and the second winding drum 5 can be used to store the protective net 7, and the screw motor 4 can be used to drive the screw 9 to operate, and the moving block can be driven to move during the operation of the screw 9, and the movement of the moving block can synchronously drive the second winding drum 5 to move, so that the protective net 7 can be stretched, and then under the action of the limiting round block 12, the winding roller 10 and the rotating circular shaft 11 can be conveniently installed to prevent the winding roller 10 and the rotating circular shaft 11 from offsetting during use, which makes it impossible for the protective net 7 to be moved. During the extension operation, the rotating motor 8 can be used to drive the rotating shaft 11 to rotate. During the rotation of the rotating shaft 11, the winding roller 10 can be synchronously driven to rotate, so that the protective net 7 can fall off from the peripheral side of the winding roller 10, which is convenient for subsequent installation operations. After that, under the action of the mounting block 13, the first clamping block 15 and the second clamping block 17 can be connected together. By using the cross plate 14 and the connecting rod 16, the second clamping block 17 can be engaged with one side of the first clamping block 15. Through the cooperation of the first clamping block 15 and the second clamping block 17, the rotating shaft 11 can be prevented from reversing during the rotation process, causing the protective net 7 to become knotted, causing the protective net 7 to be damaged and affecting subsequent use.

[0028] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.
