Description

Technical Field

[0001] This utility model belongs to the field of water conservancy engineering technology, and in particular relates to a fence for water conservancy projects. Background Technology

[0002] In water conservancy projects, fences play a very important role. During the construction of dams for water storage and utilization, environmental issues often lead to large floating objects on the water surface. Manual cleaning is extremely time-consuming and labor-intensive, thus requiring the use of fences in water conservancy projects to intercept them.

[0003] However, in the existing water conservancy projects, when floating objects are blocked by the fences during use, they are difficult to retrieve and will block the fences in the long run, affecting the water flow and causing the water level in the upstream of the river to rise, which poses certain safety hazards. Moreover, when floods occur and rapid flood discharge is required, the fences fixed in the river channel will also obstruct the water flow and affect the flood discharge speed. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a fence for water conservancy projects, and the technical solution adopted is as follows:

[0005] A fence for water conservancy projects includes an extended platform set in a river channel, a semi-circular lifting platform set in the extended platform, a swivel groove for installing a rotating shaft in the lifting platform, and fences set opposite each other on both sides of the rotating shaft; a lifting slope and a falling slope are set on both sides of the swivel groove in the lifting platform, and a garbage storage area is set between the lifting slope and the falling slope.

[0006] At the junction of the canal and the extended platform, a mounting frame is fixed by a column. A rotary motor is installed above the mounting frame, and the shaft end of the rotary motor passes through the mounting frame and is connected to the rotating shaft below.

[0007] Furthermore, a T-shaped slot is provided on the surface of the rotating shaft, and a T-shaped block matching the slot is provided at one end of the fence. By inserting the block into the slot, the fence can be rotated by the rotating shaft and can also slide along the length of the slot.

[0008] Furthermore, a roller is provided at the lower end of the other side of the fence. The bottom of the roller protrudes 1-2 cm from the lower surface of the fence, so that the intercepted garbage can be pushed to the garbage storage area without hindering the rotation of the fence.

[0009] Furthermore, a positioning post is installed at the bottom of the canal, and an opening that matches the positioning post is provided at the lower end of the rotating shaft to ensure that the fence remains stable during rotation and to prevent displacement.

[0010] Furthermore, the rotation radius of the fence, the width of the canal, and the radius of the lifting platform are all equal, enabling the rotating fence to effectively intercept garbage and floating debris in the canal.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This invention utilizes a fence that rotates 180 degrees periodically under the drive of a rotating shaft to effectively intercept garbage and floating debris in the canal. During the rotation, the garbage and floating debris are pushed to a designated storage area, thus completing the processing of the intercepted garbage and floating debris and achieving automatic cleaning of the fence. Furthermore, as the fence rotates back into the canal, the impact of the water flow further washes away any remaining fine debris on the fence surface, reducing the probability of clogging.

[0013] During flood discharge, the barrier can be rotated 90 degrees to align with the flow line of the river channel, thus avoiding obstruction of water flow and ensuring flood discharge efficiency. Attached Figure Description

[0023] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0024] As attached Figure 1-7 As shown.

[0025] A fence for hydraulic engineering includes an extended platform 2 installed within a river channel 1, and a semi-circular lifting platform 3 located within the extended platform 2, as shown in the attached figure. Figure 5 As shown, a swivel groove 34 for installing a rotating shaft 6 is provided at the center of the lifting platform 3. A lifting slope 31 and a falling slope 32 are provided on both sides of the swivel groove 34 in the lifting platform 3. A garbage storage area 33 is provided between the lifting slope 31 and the falling slope 32.

[0026] At the junction of the canal 1 and the extended platform 2, a mounting frame 4 is fixed by a column 11. A rotary motor 5 is installed above the mounting frame 4. The shaft end of the rotary motor 5 passes through the mounting frame 4 and is connected to the rotating shaft 6 below for transmission.

[0027] Two fences 7 are installed opposite each other on the outside of the rotating shaft 6. The fences 7 and the rotating shaft 6 are slidably connected. The specific connection structure is as follows: a T-shaped slot 61 is opened on the surface of the rotating shaft 6, and a T-shaped block 71 matching the slot 61 is provided at one end of the fence 7. By inserting the block 71 into the slot 61, the fence 7 can be rotated by the rotating shaft 6 and can also slide along the length direction of the slot 61.

[0028] A roller 72 is provided at the lower end of the other side of the fence 7, which can support the fence 7 while it rotates.

[0029] Furthermore, in order to achieve the positioning and installation of the rotating shaft 6, a positioning post 8 is provided at the bottom of the canal 1, and an opening that cooperates with the positioning post 8 is provided at the lower end of the rotating shaft 6 to ensure that the fence remains stable during rotation and avoids displacement.

[0030] The usage process is as follows: The usage status of this device is shown in the attached figure. Figure 1As shown, a fence 7 is perpendicular to the flow direction of the canal 1 and is used to intercept garbage and floating objects. After interception for a period of time, the rotary motor 5 is started, driving the lower rotating shaft 6 to rotate 180 degrees. During this rotation, the fence 7 in the canal 1 pushes the intercepted garbage and floating objects up the lifting slope 31 to the garbage storage area 33. Since the surface height of the lifting platform 3 is higher than the water level in the canal 1, after the garbage and floating objects are pushed out of the water, larger garbage and floating objects can fall into the garbage storage area 33 under the action of gravity. The garbage storage area 33 can be cleaned regularly thereafter.

[0031] Some of the trash adhering to the surface of the fence 7 can also be removed by the impact of the water flow as the fence 7 slides from the descending slope 32 into the canal 1. Moreover, because the trash adhering to the surface of the fence 7 is small in size, it will not affect the downstream water area after being washed away by the water flow.

[0032] Therefore, during use, it is only necessary to manually remove the garbage that severely clogs the mesh of the fence during regular inspections.

[0033] As the fence 7 rotates within the canal 1, the fence 7 at the original garbage storage area 33 slowly descends from the descent slope 32 of the lifting platform 3 into the canal 1, eventually becoming perpendicular to the flow direction of the canal 1, ready to intercept new garbage and floating debris. This periodic rotation achieves continuous interception and cleaning of garbage in the canal, effectively improving the cleanliness of the waterway.

[0034] During the rotation of the fence 7, with the assistance of the bottom roller 72 and the slope of the lifting platform 3, the fence 7 can move up and down along the length of the rotating shaft 6. In order to ensure that the rotating fence 7 can effectively intercept garbage and floating objects in the canal 1, the rotation radius of the fence 7, the width of the canal 1, and the radius of the lifting platform 3 are all equal.

[0035] As the fence 7 pushes the garbage and floating objects into the garbage storage area 33, the height of the fence 7 gradually increases as it moves away from the water surface, and the garbage and floating objects gradually fall to the bottom of the fence 7. Therefore, in order to prevent the garbage and floating objects from escaping from the bottom of the fence 7, the bottom end of the roller 72 protrudes no more than 2cm from the lower surface of the fence 7. This way, while not hindering the rotation of the fence 7, the intercepted garbage can be pushed to the garbage storage area 33 in a unified manner.

[0036] During use, the cycle time of the rotary motor 5 can be set according to the amount of garbage and floating objects in the canal 1.

[0037] During use, when flood discharge is required, the rotating motor 5 can be controlled to rotate 90 degrees to erect two fences 7 at the junction of the river channel 1 and the extended platform 2. After the flood recedes, the rotating motor 5 can be controlled to rotate 90 degrees again to restore the fences 7 to their normal interception position.

[0038] The rotary motor 5 in this solution is a stepper motor, which is directly purchased from the market. Its installation, connection and setting methods are all common methods, and no creative work is required from those skilled in the art. Therefore, it will not be described in detail here.

[0039] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
