[0027] As Figs. 1 to 4 Indicated, the present embodiment provides a kind of combined support structure suitable for wind power foundation pit excavation, comprising:

[0028] The protection plate 1 is fixed with a through hole 2, an inclined arc-shaped plate 3 is fixedly installed on the outer side wall of the protection plate 1, the inclined arc-shaped plate 3 is arranged in a state of being high in the middle and low on both sides, so as to facilitate the self sliding of impurities such as gravel, the through holes 2 are uniformly arranged below the inclined arc-shaped plate 3, the inclined arc-shaped plate 3 can naturally protect the through holes 2, a rotating ball 4 is rotatably installed on the inclined arc-shaped plate 3, a rotating plate 5 is fixedly installed through the rotating ball 4, a small part of the rotating plate 5 extends out of the rotating ball 4, and the remaining part extends out of the rotating ball 4 in a slanting downward manner, an elastic element is arranged between the lower half of the rotating plate 5 and the bottom of the inclined arc-shaped plate 3, the elastic element is a metal elastic sheet, so that the rotating plate 5 and the rotating ball 4 have elastic restoring force and can be restored to the initial position under the condition of no external force;

[0029] A bent plate 6 is fixedly installed outside the lower half of the rotating plate 5, a first ball 7 is fixedly installed on the top of the bent plate 6, the first ball 7 is arranged outside the inclined arc-shaped plate 3, a fixed rod 8 is fixedly installed outside the side wall of the lower half of the rotating plate 5, a second ball 9 is fixedly installed outside the fixed rod 8, and the second ball 9 is arranged outside the through hole 2, so that the second ball 9 can rub and press the through hole 2;

[0030] A first combined cylinder 10 and a second combined cylinder 12 are fixedly installed on the left and right outer sides of the protection plate 1, the vertical surfaces of the first combined cylinder 10 and the second combined cylinder 12 in contact with the inclined arc-shaped plate 3 are arranged in an open manner, so that the impurities self sliding on the inclined arc-shaped plate 3 can automatically fall into the first combined cylinder 10 and the second combined cylinder 12, the direction of the first combined cylinder 10 and the second combined cylinder 12 towards the outside of the protection plate 1 is arranged in an open manner, so as to facilitate the centralized cleaning of workers, a combined rod 11 is fixedly installed on the first combined cylinder 10, one end of the combined rod 11 extends out of the first combined cylinder 10, and the other end is fixedly installed on the side wall of the protection plate 1, a combined hole 13 is arranged on the second combined cylinder 12, the horizontal position of the combined hole 13 is the same as that of the combined rod 11, the diameter of the combined hole 13 is the same as that of the combined rod 11, so as to facilitate the insertion of the combined rod 11 into the combined hole 13, support angle plates 14 are fixedly installed on the inner and outer side walls of the bottom of the protection plate 1, which provides an auxiliary positioning effect for the installation of the protection plate 1 and improves the stability.

[0031] In the above technical solution, when the protective plate 1 is used to support the foundation pit, the protective plate 1 stands at the edge of the foundation pit, and the protective plate 1 can intercept and protect the gravel outside the foundation pit, especially when the staff or equipment moves on the edge of the foundation pit, the splashing gravel can be intercepted by the protective plate 1. At the same time, the gravel and other impurities splashed on the protective plate 1 can fall on the inclined arc plate 3 and slide downward along the inclined arc plate 3 to the left and right sides of the protective plate 1. The fallen gravel and other impurities will fall into the No. 1 combination tube 10 and the No. 2 combination tube 12 and be collected. Then the staff can perform centralized cleaning operations at the bottom of the No. 1 combination tube 10 and the No. 2 combination tube 12, and the setting of the through hole 2 on the protective plate 1 can provide The slanted curved plate 3 is provided with a through hole 2, which can effectively intercept and protect the impurities such as scattered gravel and prevent most of the impurities such as gravel from falling into the site through the through hole 2. When the impurities such as gravel slide downward on the slanted curved plate 3, the impurities such as gravel will pass through the top of the rotating plate 5. When passing the top of the rotating plate 5, the impurities such as gravel will generate a driving force on the rotating plate 5, causing the rotating plate 5 to rotate counterclockwise, and the rotating plate 5 will drive the curved plate 6 to rotate counterclockwise. Then, when the impurities such as gravel are separated from the rotating plate 5, the rotating plate 5 will rotate clockwise back to the initial position due to the elastic force of the elastic element. At this time, the rotating plate 5 will drive the curved plate 6 to rotate clockwise. When the movable plate 5 is moved back to the original position, the movable plate 6 will move back to the original position, and the movable plate 6 will move back to the original position, so that the movable plate 6 can move back to the original position, thereby generating vibration, thereby promoting the sliding speed of the gravel and other impurities on the inclined curved plate 3, and improving the sliding cleaning efficiency. If the gravel and other impurities near the top of the inclined curved plate 3 move slowly and stay near the rotating plate 5, the remaining gravel and other impurities will continue to slide downward, and the subsequent gravel and other impurities will collide with the low-position rotating plate 5. At this time, the gravel and other impurities will increase the downward impact force, thereby making it easier to collide with the rotating plate 5 and generate rotation, so that the bent plate 6 drives the first ball 7 to collide with the bottom of the inclined curved plate 3 to generate vibration, and this vibration will promote the sliding of gravel and other impurities near the high-position rotating plate 5, thereby It can prevent debris and other impurities from staying and clogging near the high-positioned rotating plate 5, and prevent the rotating plate 5 from getting stuck. During the rotation of the rotating plate 5, the rotating plate 5 will drive the fixed rod 8 to follow the rotation, and the follow-up rotation of the fixed rod 8 will drive the No. 2 ball 9 to follow the rotation. The follow-up rotation of the No. 2 ball 9 will intermittently perform a contact and friction operation on the through hole 2, so that the through hole 2 will vibrate during the contact and friction with the No. 2 ball 9, and then the inside of the through hole 2 itself can be cleaned, ensuring the smoothness of ventilation and improving work efficiency. When installing the protective plate 1, if the edge length of the foundation pit is too long, it can be combined. At this time, it is only necessary to insert the combination rod 11 on another group of protective plates 1 into the combination hole 13 of the current protective plate 1 for combination operation.The working range of the protective plate 1 can be lengthened, the combination mode is convenient to mount and dismount, and the mounting combination efficiency is improved, and the operation of the worker is simplified.

[0032] In summary, by arranging the through hole 2 and the inclined arc-shaped plate 3 on the protective plate 1, certain ventilation effect is provided, the weight of the protective plate is reduced, the installation and maintenance are facilitated, the splashed gravel and impurities can be effectively intercepted and protected, most of the gravel and impurities are prevented from falling into the site through the through hole 2, and the sliding efficiency of the gravel and impurities is promoted through the arrangement of the rotating plate 5, and the working cleaning efficiency is improved.

[0033] The above detailed description is used to further describe the purpose, technical scheme and beneficial effects of the utility model, and it should be understood that the above description is only a specific embodiment of the utility model, and is not used to limit the protection scope of the utility model, and any modification, equivalent replacement, improvement and the like within the spirit and principle of the utility model should be included in the protection scope of the utility model.
