Description

Technical Field

[0001] The utility model relates to the technical field of municipal engineering, in particular to a protective device for a slope of a water conservancy and hydropower project. Background Art

[0002] Slope protection devices are usually used in water conservancy and hydropower projects, and are often used to protect against falling rocks or to limit the weathering and spalling of rock and soil on slopes.

[0003] However, the existing slope protection devices are not convenient for large-scale deployment. For example, a slope protection device disclosed in Chinese patent publication number "CN213061825U" has a limited length due to its structural limitations, so a large number of devices are needed to meet the needs when deployed on a large scale, which not only increases unnecessary costs for transportation, but also makes the large-scale deployment of the device inefficient. Accordingly, the present application proposes a slope protection device for water conservancy and hydropower projects. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a protective device for the slope of a water conservancy and hydropower project.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The cam is provided with a plurality of locking plates, and the locking plates are provided with a plurality of locking plates, the locking plates having the plurality of locking plates being respectively provided with a locking cam and a locking pawl.

[0007] Preferably, the front end of the pawl fits between the teeth of the ratchet, and the wire hooking grooves are obliquely symmetrically distributed at the upper end and the lower end of the rotating shaft.

[0008] Preferably, the baffle is made of plastic, and the rotating shaft and ratchet are made of metal.

[0009] Preferably, the specifications of each baffle are the same, and only the two baffles at the front end and the rear end of each group of baffles have baffles slidably connected in their receiving grooves.

[0010] Preferably, the rotating shaft can be taken out from the fixing rod.

[0011] Preferably, a matching groove is provided on the outer surface of the fixing rod close to the baffle, and the matching groove is in contact with the side wall of the baffle.

[0012] The utility model has the following beneficial effects:

[0013] 1. By setting up the wire rope and the baffle, the device can be rolled up for transportation, which saves the space in the transport vehicle and increases the number of single deliveries. This saves costs when large-scale transportation is required, reduces the number of transportations, and thus improves transportation efficiency.

[0014] 2. By setting blocks and ratchets, the wire rope can be tightened and kept in a tightened state, so that a group of baffles can be tightened and fit tightly, thereby achieving a protective effect. Since the main part of the device is connected by wire ropes, the length of the device can be flexibly increased or decreased according to the length required by the project, which improves the efficiency of the device when deployed on a large scale.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-7 , a protective device for the slope of a water conservancy and hydropower project comprises a fixed rod 1 and a block 4. The fixed rod 1 is provided with four threading holes 5. A limiting groove 16 is provided in the block 4. A steel wire rope 2 is passed through each threading hole 5. Both ends of the steel wire rope 2 are fixedly connected with a tightening pin 7. The tightening pin 7 at one end of the steel wire rope 2 is slidably connected in the limiting groove 16. A plurality of baffles 6 are passed through the steel wire rope 2. A receiving groove 8 is provided on the side wall of the baffle 6. The block 4 is slidably connected in the receiving groove 8. The internal rotation of the fixed rod 1 is connected with a rotating shaft 3. Two ratchets 10 are fixedly connected to the rotating shaft 3. A large telescopic rod 15 is fixedly connected to the inner wall of the fixed rod 1. A spring 12 is fixedly connected to the large telescopic rod 15. A small telescopic rod 14 is fixedly connected to one end of the spring 12 away from the large telescopic rod 15. A ratchet 13 is fixedly connected to one end of the small telescopic rod 14 away from the spring. A hooking groove 11 is provided at the upper and lower ends of the rotating shaft 3. It should be noted that the maximum extension position of the small telescopic rod 14 is the position where it fits with the teeth of the ratchet 10 .

[0025] The front end of the pawl 13 fits between the teeth of the ratchet wheel 10, and the wire hooking grooves 11 are obliquely symmetrically distributed at the upper end and the lower end of the rotating shaft 3. It should be noted that the tightening pin 7 can pass through the threading hole 5 when placed horizontally.

[0026] The material of the baffle plate 6 is plastic, and the rotating shaft 3 and the ratchet wheel 10 are metal. It should be noted that in use, every two baffles 4 are distributed diagonally.

[0027] When using the device, first take out the rotating shaft 3 from the fixing rod 1, then horizontally insert the tightening pin 7 into the two threading holes 5 distributed along the diagonal line, and then put another pair of tightening pins 7 distributed along the diagonal line into the limiting groove 16. There is a concave part on the bottom surface of the limiting groove 16. After the tightening pin 7 is placed in the limiting groove 16, it will fall into the concave part under the action of gravity. Then, pour out the tightening pin 7 inserted into the fixing rod 1 from the fixing rod 1, and then place it in the two hooking grooves 11 at the upper end and the lower end of the rotating shaft 3 according to the upper and lower positions. , then rotate counterclockwise to wind the wire rope 2, then insert the rotating shaft 3 into the fixed rod 1, and then rotate the rotating shaft 3 counterclockwise. At this time, the wire rope 2 will be gradually tightened, and under the action of the ratchet 10 and the pawl 13, the wire rope 2 cannot be loosened. At this time, the block 4 will slide into the storage groove 8. Because two of the tightening pins 7 are connected to the block 4, the block 4 will press the baffle 6 along the direction of the force of the wire rope 2, so that the device becomes a whole, and then the device is vertically inserted into the position to be protected to complete the arrangement.

[0028] If the length of the device is greater than the length required by the project, the tightening pin 7 can be passed horizontally through the threading hole 5, and then the baffle 6 can be removed to reduce the overall length of the device to meet different project requirements. When the length of the device is less than the length required by the project, the baffle 6 can be strung onto the wire rope 2 in the same way to increase the overall length of the device.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
