Description

Technical Field

[0001] The invention relates to the technical field of construction protection, and in particular to a slope construction protection device for a water conservancy and hydropower project. Background Art

[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater in order to achieve the purpose of eliminating harm and promoting benefits. In water conservancy and hydropower projects, slopes often refer to embankment slopes or steep slopes in river banks, dams, reservoirs, channels and other projects. Slope construction protection devices are important facilities used to protect slope stability and prevent geological disasters such as landslides and collapses. They are generally active protection nets and concrete walls.

[0003] After searching, the invention patent with Chinese patent number CN116676962A discloses an anchoring device and a slope protection net. Compared with the prior art, the invention patent with Chinese patent number CN116676962A does not require hand support when knocking the inner anchor assembly, which can reduce the safety hazard during construction. The positioning ring of the positioning part limits the sliding trajectory of the inner anchor assembly, which can effectively prevent the outer anchor sleeve from shifting and ensure that the inner anchor assembly will not tilt when it goes deep into the ground.

[0004] However, in actual use, the above device fixes the protective net by directly inserting the anchor rod into the soil. The contact area between the anchor rod and the soil is small, which may result in insufficient bearing capacity of the anchor rod. When the protective net is subjected to high-intensity wind pressure, snow pressure and other loads, the anchor rod is prone to displacement, affecting the protection work. Therefore, a slope construction protection device for water conservancy and hydropower projects is proposed. Summary of the invention

[0005] The purpose of the present invention is to solve the problem in the prior art that it is difficult for anchor rods to obtain sufficient connecting force, resulting in insufficient bearing capacity of the anchor rods, which cannot withstand the protective net and the wind pressure, snow pressure and other loads it bears, thus affecting the progress of the protective work, and to propose a slope construction protection device for water conservancy and hydropower projects.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A slope construction protection device for water conservancy and hydropower engineering comprises a protection net, a plurality of anchor rods are installed on the outer side of the protection net, a movable rod is movably connected to the inner side of the anchor rod, a drill bit is installed on the end of the movable rod, a plurality of square grooves are opened inside the drill bit, a movable plate is symmetrically and movably connected to the inner side of the square groove, a plurality of spiral blades are rotatably connected to the outer side of the anchor rod, when the anchor rod and the drill bit are inserted into the soil, part of the soil moves between the anchor rod and the drill bit through the square groove, and the soil can only enter but not exit through the movable plate, and the spiral blades can be driven to rotate when the drill bit rotates, and the force generated by the rotation of the spiral blades guides the surrounding soil to between the anchor rod and the drill bit, so that when the anchor rod and the drill bit are subjected to the reverse pulling force, the end face of the drill bit is blocked, thereby improving the pull-out resistance of the anchor rod and the drill bit;

[0008] The drill bit is provided with a connecting assembly, which includes a plurality of first square plates movably connected to the outside of the anchor rod, a pressure block installed on the side of the first square plate, a plurality of insertion blocks slidably arranged on the inside of the drill bit, an expansion airbag installed on the inside of the insertion block, and a pressure airbag installed on the side of the first square plate. A connecting pipe is installed between the pressure airbag and the expansion airbag. When the drill bit moves downward, it drives the insertion block to squeeze the inclined surface of the pressure block. The insertion block moves to the outside of the drill bit and is inserted into the inside of the soil through the squeezing force. When the drill bit moves downward, it squeezes the pressure airbag. The gas generated by the pressure of the pressure airbag is transmitted to the expansion airbag through the connecting pipe. The expansion airbag expands and presses against the soil on the surface of the insertion block, thereby increasing the connectivity between the drill bit and the soil, forming a complex connection relationship, and improving the stability of the protection net when performing slope protection work.

[0009] The above technical solution further includes:

[0010] A fixed plate is symmetrically installed on the inner side of the square groove, and the side of the fixed plate is rotatably connected to the first rotating rod. The movable plate is installed on the end of the first rotating rod. A torsion spring is installed between the movable plate and the fixed plate, so that the two movable plates are closed in the normal state or in the reverse pulling state.

[0011] A plurality of open grooves are provided on the inner side of the drill bit, a sliding groove is provided on the inner side of the open groove, a sliding block is slidably provided on the inner side of the sliding groove, a spring is installed on the side of the sliding block, a side of the spring away from the sliding block is fixedly connected to the side wall of the sliding groove, and the sliding block is fixedly connected to the insertion block, so that the insertion block can move along the sliding groove through the sliding block.

[0012] The size of the sliding groove opening is matched with the size of the sliding block, and the cross sections of the sliding groove and the sliding block are both convex, thereby ensuring the sliding stability of the insertion block.

[0013] The outer side of the anchor rod is rotatably connected with a rotating ring, and a plurality of the first square plates are evenly installed on the outer side of the rotating ring in a circumferential manner. The first square plates are movably connected to the drill bit, so that the rotating ring can rotate with the drill bit when it rotates.

[0014] The pressure block is installed at one end of the first square plate extending to the inner side of the opening groove, a second square plate is installed on one side of the first square plate close to the pressure block, and the pressure airbag is installed on the upper part of the second square plate.

[0015] The cross section of the pressure block is trapezoidal, and the pressure block is located on the movement track of the insertion block. When the insertion block moves downward, it presses the inclined surface of the pressure block.

[0016] The pressurized air bag is located on the movement track of the drill bit, and the pressurized air bag can be squeezed when the drill bit moves downward.

[0017] A plurality of fixing blocks are installed on the upper part of the expansion airbag, and the plurality of fixing blocks are evenly distributed on the expansion airbag in a horizontal manner. After the expansion airbag is inflated, the plurality of fixing blocks can be driven to press against the soil.

[0018] A plurality of third-party rectangular plates are installed on the outside of the anchor rod, and the side of the third-party rectangular plate is rotatably connected to a second rotating rod, and the spiral blades are installed on the outside of the second rotating rod. A first bevel gear is installed on the end of the second rotating rod away from the third-party rectangular plate, and a second bevel gear is installed on the upper part of the drill bit. The second bevel gear is meshed with the first bevel gear, and when the drill bit rotates, it can drive the spiral blades on the two rotating rods to rotate.

[0019] The present invention has the following beneficial effects:

[0020] 1. In the present invention, by setting a drill bit, after the anchor rod and the drill bit are inserted into the soil, part of the soil will fill into the groove between the anchor rod and the drill bit. This filling effect can increase the contact area between the anchor rod and the drill bit and the soil to a certain extent, thereby increasing the friction between the anchor rod and the soil, and improving the pull-out resistance of the anchor rod and the drill bit, thereby increasing the load of the protective net when protecting soft soil.

[0021] 2. In the present invention, a connection assembly is provided to allow the insertion block to be inserted into the inner side of the soil, and the inflatable airbag is inflated to press against the soil on the surface of the insertion block, thereby increasing the connectivity between the drill bit and the soil, forming a complex connection relationship, and improving the bearing capacity of the anchor rod and the stability of the protective net during slope protection work.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Embodiment 1

[0032] like Figure 1 - Figure 7As shown, a slope construction protection device for water conservancy and hydropower engineering proposed by the present invention comprises a protection net 1, a plurality of anchor rods 2 are installed on the outer side of the protection net 1, a movable rod 3 is movably connected to the inner side of the anchor rod 2, a drill bit 4 is installed on the end of the movable rod 3, a plurality of square grooves 18 are opened inside the drill bit 4, a movable plate 27 is symmetrically movably connected to the inner side of the square groove 18, a plurality of spiral blades 24 are rotatably connected to the outer side of the anchor rod 2, when the anchor rod 2 and the drill bit 4 are inserted into the soil, part of the soil moves to between the anchor rod 2 and the drill bit 4 through the square groove 18, and the soil can only enter but not exit through the movable plate 27, when the drill bit 4 rotates, the spiral blades 24 can be driven to rotate, and the force generated by the spiral blades 24 when rotating guides the surrounding soil to between the anchor rod 2 and the drill bit 4, so that when the anchor rod 2 and the drill bit 4 are subjected to the reverse pulling force, the end face of the drill bit 4 is blocked, thereby improving the pull-out resistance of the anchor rod 2 and the drill bit 4;

[0033] A connecting assembly is provided on the drill bit 4, and the connecting assembly includes a plurality of first square plates 6 movably connected to the outside of the anchor rod 2, a pressure block 7 installed on the side of the first square plate 6, a plurality of insertion blocks 11 slidingly arranged on the inside of the drill bit 4, an expansion air bag 12 installed on the inside of the insertion block 11, and a pressure air bag 9 installed on the side of the first square plate 6. A connecting pipe 13 is installed between the pressure air bag 9 and the expansion air bag 12. When the drill bit 4 moves downward, it drives the insertion block 11 to squeeze the inclined surface of the pressure block 7. The insertion block 11 moves to the outside of the drill bit 4 and is inserted into the inside of the soil by the squeezing force. When the drill bit 4 moves downward, it squeezes the pressure air bag 9. The gas generated by the pressure of the pressure air bag 9 is transmitted to the expansion air bag 12 through the connecting pipe 13. The expansion air bag 12 expands and presses against the soil on the surface of the insertion block 11, thereby increasing the connectivity between the drill bit 4 and the soil, forming a complex connection relationship, and improving the stability of the protection net 1 during slope protection work.

[0034] A fixed plate 19 is symmetrically installed on the inner side of the square groove 18, and the side of the fixed plate 19 is rotatably connected to the first rotating rod 20. A movable plate 27 is installed at the end of the first rotating rod 20. A torsion spring 21 is installed between the movable plate 27 and the fixed plate 19, so that the two movable plates 27 are closed in the normal state or in the reverse pulling state.

[0035] A plurality of third-party rectangular plates 22 are installed on the outer side of the anchor rod 2, and the side of the third-party rectangular plate 22 is rotatably connected to the second rotating rod 23. The spiral blades 24 are installed on the outer side of the second rotating rod 23. A first bevel gear 25 is installed on the end of the second rotating rod 23 away from the third-party rectangular plate 22. A second bevel gear 26 is installed on the upper part of the drill bit 4. The second bevel gear 26 is meshed with the first bevel gear 25. When the drill bit 4 rotates, it can drive the spiral blades 24 on the second rotating rod 23 to rotate.

[0036] In this embodiment, when protection work is needed, multiple anchor rods 2 can be inserted into the slope, and then the protection net 1 can be used for protection. When the anchor rods 2 are inserted into the soil, the drill bit 4 can be driven to be inserted into the soil. When the drill bit 4 moves, part of the soil can be moved between the anchor rods 2 and the drill bit 4 through the square groove 18. The two movable plates 27 inside the square groove 18 can be driven to close in the normal state or in the reverse pulling state by the force of the torsion spring 21, so that the soil can only be pulled in but not out. The drill bit 4 can be rotated by the movable rod 3, and the second bevel gear 26 can be driven to rotate when the drill bit 4 rotates. Since the second bevel gear 26 is meshed with the first bevel gear 25, the second bevel gear 26 can drive the first bevel gear 25 to rotate when it rotates, thereby driving the spiral blades 24 on the second rotating rod 23 to rotate. The guiding force generated by the rotation of the spiral blades 24 can guide the soil around the drill bit 4 to between the anchor rod 2 and the drill bit 4, so that there is more soil between the anchor rod 2 and the drill bit 4, so that when the anchor rod 2 and the drill bit 4 are subjected to the reverse pulling force, the end face of the drill bit 4 is blocked, thereby improving the pull-out resistance of the anchor rod and the drill bit, thereby increasing the load of the protective net when protecting soft soil.

[0037] Embodiment 2

[0038] like Figure 1 - Figure 7 As shown, based on the first embodiment, a plurality of open grooves 10 are provided on the inner side of the drill bit 4, a sliding groove 14 is provided on the inner side of the open groove 10, a sliding block 15 is slidably provided on the inner side of the sliding groove 14, a spring 16 is installed on the side of the sliding block 15, a side of the spring 16 away from the sliding block 15 is fixedly connected to the side wall of the sliding groove 14, the sliding block 15 is fixedly connected to the insertion block 11, so that the insertion block 11 moves along the sliding groove 14 through the sliding block 15.

[0039] The size of the opening of the sliding groove 14 matches the size of the sliding block 15 , and the cross-sections of the sliding groove 14 and the sliding block 15 are both convex, thereby ensuring the sliding stability of the insertion block 11 .

[0040] The outer side of the anchor rod 2 is rotatably connected with a rotating ring 5, and a plurality of first square plates 6 are evenly installed on the outer side of the rotating ring 5 in a circumferential manner. The first square plates 6 are movably connected to the drill bit 4, so that the rotating ring 5 can rotate along with the drill bit 4 when it rotates.

[0041] The pressure block 7 is installed at one end of the first square plate 6 extending to the inner side of the opening groove 10 , and a second square plate 8 is installed on the side of the first square plate 6 close to the pressure block 7 , and the pressure airbag 9 is installed on the upper part of the second square plate 8 .

[0042] The cross section of the pressure block 7 is trapezoidal, and the pressure block 7 is located on the movement track of the insertion block 11 . When the insertion block 11 moves downward, it presses the inclined surface of the pressure block 7 .

[0043] The pressurized airbag 9 is located on the movement track of the drill bit 4 , and the pressurized airbag 9 can be squeezed when the drill bit 4 moves downward.

[0044] A plurality of fixing blocks 17 are installed on the upper part of the expansion airbag 12 . The plurality of fixing blocks 17 are evenly distributed on the expansion airbag 12 in a horizontal manner. After the expansion airbag 12 is inflated, the plurality of fixing blocks 17 can be driven to press against the soil.

[0045] In this embodiment, the movable rod 3 can be pressed to drive the drill bit 4 to continue to move into the soil, so that the drill bit 4 moves in the direction away from the anchor rod 2, and at the same time drives the insertion block 11 to move downward. At this time, the insertion block 11 squeezes the inclined surface of the pressure block 7, and the squeezing force can drive the insertion block 11 to move along the sliding groove 14 through the sliding block 15. At this time, the spring 16 contracts until the insertion block 11 moves to the outside of the opening groove 10 and inserts into the inside of the soil. At the same time, when the drill bit 4 moves downward, it can squeeze the pressurized airbag 9. The gas generated by the pressure of the pressurized airbag 9 is transmitted to the expansion airbag 12 through the connecting pipe 13. The expansion airbag 12 expands and presses against the soil on the surface of the insertion block 11, and at the same time drives multiple fixed blocks 17 to press against the soil, thereby increasing the connectivity between the drill bit 4 and the soil, forming a complex connection relationship, and improving the bearing capacity of the anchor rod and the stability of the protective net during slope protection work.
