[0044] The utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0045] Figure 1 As shown, it is a set of the utility model installed on the side slope of the triangular truss of the beam forming machine, and in this drawing, the utility model is in the closed state (rainproof mode), and accordingly, Figures 2 to 6 Each schematic diagram in the closed state; Figures 7 to 11 Each schematic diagram in the open state (sun-shading and ventilation mode) of the utility model.

[0046] As shown, the utility model comprises:

[0047] The side pipe groups respectively located on the left and right sides each include a fixed side pipe 2 and a movable side pipe 3, the fixed side pipe 2 and the movable side pipe 3 are parallel to each other, and the fixed side pipe 2 is located below the movable side pipe 3, the top end and the bottom end of the fixed side pipe 2 are respectively fixed to the top cross beam and the bottom cross beam of the corresponding inclined frame of the triangular truss 102 through the connecting seat 7, and each side pipe group is adjacent to or located on the left and right side inclined beams of the corresponding inclined frame of the triangular truss 102, so as to minimize or avoid the rain leakage gap.

[0048] Further comprising a plurality of blade plates 1 arranged in sequence along the length direction of the side pipe groups between the two side pipe groups, the middle part of the lower surface of each blade plate 1 is respectively welded and fixed with two shaft rods: an inner shaft rod 4 and an outer shaft rod 5, the two shaft rods are parallel to each other and have a spacing, and the spacing distance determines the maximum distance between the movable side pipe 3 and the fixed side pipe 2 after the movable side pipe 3 is lifted.

[0049] The inner shaft rod 4 on each blade plate 1 extends out of both ends of the blade plate 1 on the left and right sides and is rotationally connected to the corresponding fixed side pipe 2, and the outer shaft rod 5 extends out of both ends of the blade plate 1 on the left and right sides and is rotationally connected to the corresponding movable side pipe 3, the shaft center lines of the four shaft rods on the adjacent two blade plates are parallel to each other and the projection points on the vertical plane are located at the four vertices of the parallelogram, and as shown in the figure, Figures 3 to 6 When the movable side pipe 3 moves downward towards the fixed side pipe 2 of the same group to the closed state position (for example, moves to the position where it is in close contact with the fixed side pipe 2), the upper surface of the plate body of each blade plate gradually inclines downward from the inner shaft rod 4 to the outer shaft rod 5, and the end portions of the plate bodies of the adjacent two blade plates are superimposed, the end portion of the plate body of the upper blade plate is superimposed on the end portion of the plate body of the lower blade plate, at this time, the utility model is in the closed state, because the plurality of blade plates are inclined from top to bottom and the head and tail are superimposed (the end portion of the plate body of the upper blade plate is superimposed on the end portion of the plate body of the lower blade plate), the rainwater flows outward along the inclined slope surface formed by the blade plates, thereby ensuring that at least the lower working area is protected from the rainwater.

[0050] As shown in the figure, Figures 7 to 11 When the movable side pipe 3 moves upward away from the fixed side pipe 2 of the same group, the plate body of each blade plate is flipped upward around the inner shaft rod 4, so that the vertical distance between the plate surfaces of the adjacent two blade plates reaches or approaches the maximum, at this time, the utility model is in the open state, because the vertical distance between the plates reaches or approaches the maximum, the plate inter-channel is opened to a sufficient ventilation state, so that the lower working area can at least obtain air flow from the blade group of the utility model, and if the size, shape and opening angle of the blade are properly adjusted, sufficient light can be guaranteed for a certain period of time.

[0051] Preferably, the fixed side pipe 2 and the movable side pipe 3 adopt metal square pipes of the same specification and material, so as to reduce weight, ensure strength, facilitate the opening of corresponding through holes on the pipe wall and the welding and fixation with the connecting seat, and reduce processing and installation difficulty.

[0052] Preferably, the blade plate 1 is respectively formed with an upward bending portion and a downward bending portion 11 away from the inner shaft 4 and the outer shaft 5, respectively, in the closed state, the downward bending portion 11 of the upper blade plate 1 is overlapped and shielded in front of the upward bending portion 12 of the lower blade plate, and rainwater is dripped from the lower end of the downward bending portion to the plate surface of the lower blade plate 1 in front of the upward bending portion 12, so that the rainwater can be smoothly inclined, water splashing can be prevented by the upward bending portion 12, and the overlapped upward and downward bending portions can have a better blocking and speed reduction effect on the transverse wind, so that the air flow performance is ensured while rain is blocked.

[0053] Further, the utility model also provides a locking structure which is very simple, convenient to process and low in cost, and which can lock the closed and opened states, and specific reference can be made to Figure 6 、 Figure 8 and Figure 11 , the upper pipe wall and the lower pipe wall of the movable side pipe 3 are respectively provided with an upper positioning pin hole 31 and a lower positioning pin hole 32, the upper pipe wall of the fixed side pipe 2 is respectively provided with a positioning hole corresponding to the closed state, i.e., a closed positioning hole 21, and a positioning hole corresponding to the opened state, i.e., an opened positioning hole 22, and is further provided with a locking pin 6, when reaching the corresponding state, the locking pin 6 is sequentially inserted through the upper positioning pin hole 31 and the lower positioning pin hole 32 of the movable side pipe 3 from top to bottom, and then is inserted through the positioning hole (the closed positioning hole 21 or the opened positioning hole 22) corresponding to the state of the fixed side pipe 2, the bottom end of the locking pin 6 is supported by the lower pipe wall of the fixed side pipe 2 to prevent the locking pin from being pulled out and separated;

[0054] The upper part of the locking pin 6 is jointly sleeved by the upper and lower positioning pin holes, so that the locking pin 6 is kept fixed in the radial direction of the movable side pipe, and then is limited by the sleeving of the positioning hole corresponding to the state of the fixed side pipe 2, so that the opened or closed state of the utility model is locked, and the state unlocking is also very convenient, which only needs to pull up the locking pin 6 upward to make it separate from the positioning hole of the fixed side pipe 2 corresponding to the original state.

[0055] Further, a lifting nut 61 can be screwed or welded on the top of the locking pin 6, which can facilitate the pulling up of the locking pin 6 upward when unlocking the state, and can prevent the locking pin 6 from being pulled out of the lower positioning pin hole 32 and falling off and being lost, even from bruising the worker below, when the movable side pipe 3 is moved.

[0056] Furthermore, this utility model also provides a relatively simple, reliable, and easy-to-process rotating connection structure between the shaft and the side tube, which can prevent the two from separating, specifically as follows: Figure 8 As shown, the left and right walls of the fixed side tube 2 and the movable side tube 3 each have corresponding shaft through holes. The shaft passes through the corresponding shaft through holes on both sides. The top of the shaft that passes through the side tube is screwed or welded to a side stop nut 9. The shaft body is rotatably connected to the shaft through hole. Washers 8 are respectively clamped between the side stop nut 9 and the side tube, and between the side tube and the blade plate 1. These washers reduce the frictional resistance between the two parts and improve the smoothness of rotation.

[0057] Connector 7 can be adopted as follows Figure 8 The structure shown includes a base plate and an ear plate 71. The base plate is welded and fixed to the top or bottom crossbeam of the corresponding inclined frame of the triangular truss 102. The top or bottom end of the fixed side tube is clamped onto the ear plate 71 and fixed by welding.

[0058] All components of this invention can be easily obtained from the construction site and require only simple processing. Installation and disassembly are very convenient, the invention occupies little space, is inexpensive, and has reliable performance.

[0059] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
