Detailed Description
The technical solution of the present invention will be more clearly and completely explained by the description of the preferred embodiments of the present invention with reference to the accompanying drawings.
As shown in fig. 1, a slope protection device for hydraulic engineering comprises a plurality of supporting legs 1, wherein each supporting leg 1 is arranged at intervals in a row, a winding drum 2 is arranged between two adjacent supporting legs 1, and two ends of the winding drum 2 are rotatably connected to the two supporting legs 1 through bearings. Each winding drum 2 is wound with protective nets 3, a plurality of butt joint assemblies 38 are arranged between two adjacent protective nets 3, and the butt joint assemblies 38 are used for connecting edge positions of the two adjacent protective nets 3 with each other, so that when the protective nets 3 are unreeled or wound, the protective nets 3 are simultaneously unreeled and wound through the butt joint assemblies 38.
Referring to fig. 2, the vertical section of the supporting leg 1 is L-shaped, and the bottom of the supporting leg 1 is fixed on the horizontal ground at the top of the side slope through bolts. The free end of each protection net 3 is provided with a counterweight cylinder 4, and the counterweight cylinders 4 are fixedly connected with the free end of the protection net 3 in a clamping manner.
When the protective net 3 is used, the supporting legs 1 are fixed on the horizontal ground at the top of a side slope, the counterweight barrels 4 slide freely along the inclined plane of the side slope by gravity, and the counterweight barrels 4 enable the protective net 3 to be unreeled on each winding drum 2 by gravity. When the counterweight cylinder 4 slides down on the side slope, the protective net 3 is always in a tight state, so that the counterweight cylinder cannot roll in the sliding down process of the side slope.
In order to automatically limit the unreeling length of the protective net 3 in the unreeling process, the two supporting legs 1 at the end parts are provided with pressing assemblies 37.
The pressing assembly 37 includes:
the guide seat 5 is fixed on the supporting leg 1; the vertical section is -shaped, is perpendicular to the axis of the counterweight cylinder and has an opening facing downwards.
The guide block 6 is arranged in the opening of the guide seat 5 in a relatively sliding manner, and the guide block 6 slides vertically and directly relative to the guide seat 5.
And one end of the first spring 7 is welded with the upper inner surface wall of the guide seat 5, the other end of the first spring 7 is welded with the upper surface wall of the guide block 6, the first spring 7 is in a compressed state, power is provided for the downward sliding of the guide block 6, and the first spring is always in a compressed state in the downward sliding process of the guide block 6.
The special-shaped compression bar 8 is shaped like a Chinese character 'ji', one end of the special-shaped compression bar is welded and fixed on the guide block 6, and under the elasticity of the first spring 7, the side wall of the other end of the special-shaped compression bar is in conflict with the protective net 3 on the winding drum 2 and is used for providing acting force for the protective net 3 on the winding drum 2 and preventing the protective net 3 from unreeling. The special-shaped pressing rod 8 is preferably a round rod, namely, the end face of the special-shaped pressing rod is round, and the design has the advantages that the round rod can play a role in limiting unreeling of the protective net 3 on the winding drum 2, and meanwhile, the protective net 3 cannot be scratched by the side wall of the special-shaped pressing rod 8.
The telescopic rod 9 is Z-shaped, one end of the telescopic rod is welded and fixed on the guide block 6, and the other end of the telescopic rod can be adjusted in height vertically and directly.
The plurality of slots 10 are equally divided into two groups, and the two groups of slots 10 are symmetrically arranged along the axis around the spool 2. The shafts at the two ends of the winding drum respectively pass through the corresponding supporting legs, each group of slots are distributed on the corresponding shaft of the winding drum, each group of slots are distributed on the circumferential surface of the shaft, and a plurality of slots 10 in each group of slots 10 are equally distributed along the axis of the winding drum 2.
The automatic control of the unreeling length can be realized because the thickness of the protective net 3 on the winding drum 2 is thinner and thinner when unreeling, and the guide block 6, the special-shaped compression bar 8 and the telescopic bar 9 move downwards under the recovery of the elasticity of the first spring 7. Note that although the socket 10 rotates with the rotation around the spool 2, the telescopic rod 9 does not necessarily just have to be in the socket 10 when contacting the shaft side wall around the spool 2, but as the rotation around the spool 2 continues, the telescopic rod 9 is eventually inserted into one of the sockets 10. After the telescopic rod 9 is inserted into the slot 10, the winding drum 2 is limited by the telescopic rod 9 and does not rotate any more, namely the unreeling process is automatically finished.
The first spring 7 resists unreeling around the protective net 3 on the winding drum 2 by the special-shaped compression bar 8. Specifically, the special-shaped compression bar 8 limits the unwinding speed of the protection net 3, and the unwinding speed of the protection net 3 is low, so that when the telescopic rod 9 is inserted into one of the slots 10, the telescopic rod 9 cannot be scratched due to the too high speed.
Referring to fig. 3, the telescopic rod 9 includes:

the nut 14 is connected to the outer wall of the first connecting rod 11 through threads, and is sleeved at the middle concave position of the lantern ring 13, the nut 14 can rotate relative to the lantern ring 13, and the nut 14 is in contact with the upper wall and the lower wall of the concave position of the lantern ring 13.
The user manually moves the second link 12 straight up and down with respect to the first link 11 by turning the nut 14, so that the distance the second link 12 reaches the slot 10 is changed, i.e., the user presets the distance the second link 12 moves when the second link 12 extends into the slot 10. Since the distance moved by the second link 12 is changed, the thickness of the protection net 3 which can be unreeled around the roll 2 is changed.
Referring to fig. 4, in order to limit the position of the weight cylinder 4 after the protective net 3 is completely wound, the weight cylinder 4 is prevented from being optionally unwound with the protective net 3, so that a bracket assembly is arranged on the support leg 1, and the bracket assembly is arranged on the two support legs 1 at two ends.

When the protective net 3 is paved, the counterweight cylinder 4 is required to be taken out of the arc-shaped placing groove, and then the counterweight cylinder 4 freely slides off on the inclined plane of the side slope by means of the dead weight of the counterweight cylinder 4, so that unreeling of the protective net 3 is realized.
Referring to fig. 5, after the protective net 3 is completely laid on the slope of the slope, in order to limit the weight cylinder 4, the weight cylinder 4 is fixed at the lowest end of the slope, so fixing components are disposed at both end portions of the weight cylinder 4.
