Description

Technical Field

[0001] This utility model relates to the field of protective netting technology, specifically to a reservoir slope protective netting. Background Technology

[0002] Reservoir slope protection nets are protective facilities specifically designed for reservoir slopes (which are susceptible to erosion by water flow and loosening of soil and rock). Their core function is to prevent slope collapse, rockfall, blockage of the reservoir area, or threat to dam safety, while also taking into account ecological protection. Additionally, the nets can prevent people (such as tourists and villagers) from entering dangerous slope areas, avoiding slope loosening caused by climbing or trampling, or accidents involving falls. Furthermore, they can reduce the damage to surface vegetation caused by terrestrial animals entering the slope to forage, while preventing animals from polluting the reservoir water, thus balancing the safety of personnel and the reservoir environment.

[0003] Patent CN 219430568 U discloses a slope protection net, including a right support plate and a left support plate. The bottom of both the right and left support plates is fixedly connected to an installation base. A front limiting plate is hinged to the front of both the right and left support plates. An installation groove is opened at the relative position of the right support plate and the front limiting plate. A positioning post is fixedly connected at the relative position of the installation groove opened inside the right and left support plates and the front limiting plate, which facilitates better installation of the first slope protection net and the second slope protection net.

[0004] However, the device still has the following problems:

[0005] 1. The installation of the protective net is quite complicated, and it is very inconvenient to replace the net when it is damaged.

[0006] 2. As the protective netting is used, it will deform and loosen, and it cannot be tightened again. Utility Model Content

[0007] To address the problems existing in the prior art, a reservoir slope protection net is provided to solve the problems mentioned in the above technical background.

[0008] The technical solution adopted by this utility model to solve its technical problem is:

[0009] This utility model proposes a reservoir slope protection net, including a net body, one end of which is fixed to a winding shaft, and the other end is detachably fixed to the slope via a connector. It also includes a column, the column having a space to accommodate the winding shaft. A limiting rod is slidably connected to the lower end of the column to restrict the upward movement of the winding shaft. The limiting rod is connected to the column via a first compression spring. A limiting groove that cooperates with the limiting rod is provided on the winding shaft. A pressure plate that can drive the limiting rod to slide is slidably connected to the column, and the pressure plate cooperates with the upper end of the winding shaft.

[0010] Preferably, the upper end of the take-up shaft is rotatably connected to an upper take-up shaft, and a spline shaft is provided inside the take-up shaft, which can lock the rotation of the take-up shaft and the upper take-up shaft.

[0011] Preferably, a plug rod is slidably connected to the column, the plug rod is connected to the column through a third compression spring, and the upper scroll has several slots for the plug rod to slide freely into.

[0012] Preferably, the column is slidably connected to a connecting rod capable of pushing the limiting rod to slide. A magnet that attracts the insertion rod is fixed on the connecting rod. The magnetic force of the magnet is greater than the elastic force of the third compression spring. The upper end of the connecting rod is connected to the pressure plate.

[0013] Preferably, a boss is fixedly provided at the lower end of the column, a groove is provided at the lower end of the winding shaft, and the limiting groove is annular. When the limiting rod slides into the limiting groove, the winding shaft can rotate freely through the groove and the boss.

[0014] Preferably, a locking pin is slidably connected to the boss, and the locking pin is connected to the boss through a second compression spring. The groove has a plurality of slots for the locking pin to slide freely into.

[0015] Preferably, the splined shaft is connected to the take-up shaft via a spring.

[0016] Preferably, an upper pull rope and a lower pull rope are fixed at the upper and lower ends of the net body, respectively. One end of the upper pull rope is fixedly wound around the upper winding shaft, and one end of the lower pull rope is fixedly wound around the winding shaft.

[0017] Preferably, the keys of the spline shaft are evenly distributed in the circumferential direction of the spline shaft, and the slots are evenly distributed in the circumferential direction of the upper winding shaft, with the number of slots being the same as the number of keys of the spline shaft.

[0018] Preferably, the other end of the mesh is fixed to an adjacent post via a connector.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. This utility model is equipped with a limiting rod and a pressure plate. By sliding the pressure plate, the winding shaft is placed into the column from the opening above the column. The winding shaft is placed into the column so that the lower end of the winding shaft contacts the lower end of the column. Then, the pressure plate is slid in the opposite direction. At this time, under the action of the first compression spring, the limiting rod slides into the limiting groove on the winding shaft, limiting the axial movement of the winding shaft and completing the installation of the winding shaft. When it is necessary to disassemble the winding shaft to replace the net body, simply slide the pressure plate so that the pressure plate drives the limiting rod to slide to one side, which can release the lock on the winding shaft and facilitate the removal of the winding shaft. The installation and disassembly process is simple and convenient.

[0021] 2. This utility model is equipped with a spline shaft. When the spline shaft is in contact with both the take-up shaft and the upper winding shaft at the same time, rotating the upper winding shaft can drive the take-up shaft to rotate, thereby tightening the net body as a whole. When the spline shaft is in contact with only the upper winding shaft or the take-up shaft, the upper winding shaft and the take-up shaft can rotate independently, thereby tightening the upper and lower ends of the net body separately.

Detailed Implementation

[0032] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0033] refer to Figures 1-7 This embodiment proposes a reservoir slope protection net, including a net body 1, one end of which is fixed to a winding shaft 2, and the other end is detachably fixed to the slope through a connector. It also includes a column 3, which has a space inside that can accommodate the winding shaft. The lower end of the column 3 is slidably connected to a limiting rod 4 that can restrict the upward movement of the winding shaft. The limiting rod 4 is connected to the column 3 through a first compression spring 5. The winding shaft has a limiting groove 6 that cooperates with the limiting rod 4. The column 3 is slidably connected to a pressure plate 7 that can drive the limiting rod 4 to slide. The pressure plate 7 cooperates with the upper end of the winding shaft 2.

[0034] The other end of the net body 1 is fixed to the adjacent post 3 by a connector.

[0035] Slide the pressure plate 7 and insert the take-up shaft 2 into the column 3 through the opening above the column 3, so that the lower end of the take-up shaft 2 contacts the lower end of the column 3. Then slide the pressure plate 7 in the opposite direction. At this time, under the action of the first compression spring 5, the limiting rod 4 slides into the limiting groove 6 on the take-up shaft 2 to limit the axial movement of the take-up shaft 2, thus completing the installation of the take-up shaft 2.

[0036] The size of the opening of the column 3 is adapted to the upper end of the take-up shaft 2, which can restrict the upper end of the take-up shaft 2 from sliding in the horizontal direction. After the take-up shaft 2 is placed, the pressure plate is slid to the right again so that the lower end of the pressure plate contacts the upper end of the take-up shaft 2, which can further limit the position of the take-up shaft 2.

[0037] When it is necessary to disassemble the take-up shaft 2 to replace the net body 1, simply slide the pressure plate 7 so that the pressure plate 7 drives the limit rod 4 to slide to one side, which can release the lock on the take-up shaft 2 and make it easy to take out the take-up shaft 2. The installation and disassembly process is simple and convenient.

[0038] The upper end of the take-up shaft 2 is rotatably connected to the upper winding shaft 11. A spline shaft 12 is provided inside the take-up shaft 2. The spline shaft 12 can lock the rotation of the take-up shaft 2 and the upper winding shaft 11.

[0039] Both the upper winding shaft 11 and the rewinding shaft 2 are provided with spline grooves that match the spline shaft 12, allowing the spline shaft 12 to slide freely within the spline grooves.

[0040] When the spline shaft 12 is in contact with both the take-up shaft 2 and the upper winding shaft 11, rotating the upper winding shaft 11 will also drive the take-up shaft 2 to rotate, thus tightening the net body 1 as a whole. When the spline shaft 12 is in contact with only the upper winding shaft 11 or the take-up shaft 2, the upper winding shaft 11 and the take-up shaft 2 can rotate independently, thus tightening the upper and lower ends of the net body 1 separately.

[0041] When the surface soil and rock of the slope (such as gravel and loose soil) tends to slide under the action of gravity, it will pull the protective netting and generate force. This force is almost entirely borne by the upper part of the netting. Therefore, the upper part of the protective netting usually deforms more than the lower part, so it is necessary to tighten the upper and lower ends separately.

[0042] When there is no impact from gravel or other heavy objects, the deformation of the net at both ends is similar, so the net at both ends can be tightened at the same time, improving the tightening efficiency.

[0043] A rod 13 is slidably connected to the column 3. The rod 13 is connected to the column 3 through a third compression spring 14. Several slots 15 are provided on the upper scroll 11 for the rod 13 to slide freely into.

[0044] The elastic force of the third compression spring 14 allows the insertion rod 13 to slide into the slot 15. One end of the insertion rod 13 is a bevel. When the upper winding shaft 11 tightens the mesh body 1 and rotates, the bevel can drive the insertion rod 13 to repeatedly slide into the slot 15. The insertion rod 13 allows the upper winding shaft 11 to rotate only in one direction, thus achieving locking after tightening.

[0045] The column 3 is slidably connected to a connecting rod 16 that can push the limiting rod 4 to slide. A magnet 17 that attracts the insertion rod 13 is fixed on the connecting rod 16. The magnetic force of the magnet 17 is greater than the elastic force of the third compression spring 14. The upper end of the connecting rod 16 is connected to the pressure plate 7.

[0046] When the pressure plate 7 slides, it drives the connecting rod 16 to slide downward through the inclined surface. The connecting rod 16 drives the limiting rod 4 to slide out of the limiting groove through the inclined surface. When the sliding pressure plate 7 releases the limit on the lower end of the winding shaft 2, the magnet 17 on the connecting rod 16 also slides to the same height as the insertion rod 13. At this time, the insertion rod 13 slides out of the slot 15, so that the winding shaft 2 can move up and down, which is convenient for subsequent replacement and maintenance.

[0047] A boss is fixedly provided at the lower end of the column 3, and a groove is provided at the lower end of the winding shaft 2. The limiting groove 6 is annular. When the limiting rod 4 slides into the limiting groove 6, the winding shaft 2 can rotate freely through the groove and the boss.

[0048] A locking pin 8 is slidably connected to the boss. The locking pin 8 is connected to the boss through a second compression spring 9. Several slots are provided in the groove for the locking pin 8 to slide freely into.

[0049] The elastic force of the second compression spring 9 allows the insert pin 8 to slide into the slot. One end of the pin 8 is a bevel. When the winding shaft 2 tightens the mesh body 1 and rotates, the bevel can drive the pin 8 to slide repeatedly into the slot. The pin 8 allows the winding shaft to rotate only in one direction, thus achieving locking after tightening.

[0050] The spline shaft is connected to the take-up shaft 2 via spring 10.

[0051] The upper and lower ends of the net body 1 are respectively fixed with an upper pull rope 18 and a lower pull rope 19. One end of the upper pull rope 18 is fixedly wound around the upper winding shaft 11, and one end of the lower pull rope 19 is fixedly wound around the winding shaft 2.

[0052] The keys of the spline shaft 12 are evenly distributed in the circumferential direction of the spline shaft 12, and the slots 15 are evenly distributed in the circumferential direction of the upper winding shaft 11. The number of slots 15 is the same as the number of keys of the spline shaft 12.

[0053] The number of slots 15 is the same as the number of keys on the spline shaft 12. After each tightening of the upper winding shaft 11, the slots 15 correspond to the positions of the keys on the spline shaft 12, so that the spring 10 can drive the spline shaft 12 to slide upward and reset.

[0054] Several fixing rings are fixedly installed on column 3. Detailed implementation method:

[0056] S1: Determine the area of ​​the reservoir slope that needs protection, determine the location of each column 3, and fix the bottom of the column 3 to the corresponding location by pouring concrete or by fixing bolts.

[0057] S2: Slide the pressure plate 7 and place the take-up shaft 2 into the column 3 from the opening above the column 3. After it is placed into the column 3, the lower end of the take-up shaft 2 contacts the lower end of the column 3. Then slide the pressure plate 7 in the opposite direction. At this time, under the action of the first compression spring 5, the limiting rod 4 slides into the limiting groove 6 on the take-up shaft 2 to limit the axial movement of the take-up shaft 2 and complete the installation of the take-up shaft 2.

[0058] S3: Connect the other end of the net body 1 to the fixing ring on the adjacent post 3 by means of hooks or ropes to complete the fixation of the left and right ends of the net body;

[0059] S4: When it is necessary to replace the net body 1, first disconnect the net body 1 from the fixing ring, then slide the pressure plate 7 to the left, so that the pressure plate 7 drives the connecting rod 16 to slide down through the inclined surface. The connecting rod 16 drives the limiting rod 4 to slide out of the limiting groove through the inclined surface. When the sliding pressure plate 7 releases the limit on the lower end of the winding shaft 2, the magnet 17 on the connecting rod 16 also slides to the same height as the insertion rod 13. At this time, the insertion rod 13 slides out from the slot 15, so that the winding shaft 2 can move up and down, which is convenient for subsequent replacement and maintenance.

[0060] When the net body 1 naturally loosens due to prolonged use, it is necessary to simultaneously wind up both the upper and lower ends of the net body 1. Insert the crank handle 20 into the upper winding shaft 11. The crank handle 20 has spline teeth that match the spline groove in the upper winding shaft 11. When the crank handle 20 is not pressed down, the spline shaft 12, under the action of the spring force of the spring 10, simultaneously contacts the upper winding shaft 11 and the winding shaft 2. Rotating the crank handle 20 can drive the upper winding shaft 11 and the winding shaft 2 to rotate simultaneously, thereby achieving simultaneous tightening of both the upper and lower ends of the net body 1.

[0061] When the upper part of the net body 1 becomes loose due to the impact of falling rocks or other heavy objects, and it is necessary to tighten the upper part of the net body separately, the crank handle 20 is inserted into the upper winding shaft 11. The front end of the crank handle 20 is fixed with an optical shaft. The diameter of the optical shaft is smaller than the diameter of the spline shaft 12. Press the crank handle 20 down to make the optical shaft push the spline shaft 12 down. The optical shaft is located at the position where the upper winding shaft 11 and the take-up shaft 2 meet. At this time, the spline shaft 12 only contacts the take-up shaft 2. Rotate the crank handle 20. At this time, the crank handle 20 will only drive the upper winding shaft 11 to rotate, so as to achieve independent tightening of the upper part of the net body 1.

[0062] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
