[0032] The embodiments of the utility model will be described in detail below with reference to the drawings.

[0033] Embodiment:

[0034] Referring to Figure 1 The embodiment discloses a kind of water conservancy dam's blocking slag structure, including dam main body 10, support frame 20, blocking slag net 30, cable 40, resistance plate 50 and guide wheel 60, wherein, dam main body 10 is set in the two sides of river channel, generally is built by reinforced concrete.

[0035] In the process of building the dam body 10, a mounting groove extending in the vertical direction is arranged on the dam body 10, and the mounting groove is open on one side, and the open side is located in the river channel.

[0036] Then a support frame 20 is arranged in the mounting groove on each of the two dam bodies 10, and the two ends of the slag retaining net are fixedly arranged on the two support frames 20 respectively. The support frame 20 is a T-shaped structure, and the mounting groove on the dam body 10 is T-shaped.

[0037] In the installation process, the height of the support frame 20 is slightly higher than the top surface of the dam body 10, so that the top of the slag retaining net 30 is also slightly higher than the top surface of the dam body 10.

[0038] In addition, when arranging the depth of the mounting groove, the distance between the bottom end of the mounting groove and the bottom of the river channel should be less than or equal to the annual average minimum water depth in the river channel, and the length of the support frame 20 and the height of the slag retaining net 30 should correspond to the minimum water depth, so that the lowest part of the slag retaining net 30 can intercept and clean the top surface of the water flow in the river channel.

[0039] A plurality of guide wheels 60 are arranged on the dam body 10. One end of the cable 40 is fixedly arranged in the middle of the slag retaining net, and the other end of the cable 40 is connected to the top end of the resistance plate 50 after winding around the plurality of guide wheels 60. At the same time, the resistance plate 50 is located in the middle of the river channel, and the resistance plate 50 is located downstream of the slag retaining net 30. The end of the cable 40 connected to the slag retaining net 30 extends in an inclined direction to the upstream of the river channel.

[0040] In the embodiment, the cable 40 and the guide wheel 60 are symmetrically arranged on the two dam bodies 10, and the ends of the two cables 40 are connected to the two sides of the top end of the resistance plate 50.

[0041] In the working process, the mounting groove is vertically arranged on the dam body 10, the support frame 20 is arranged in the mounting groove, and the slag retaining net 30 is arranged between the two support frames 20, and the middle part of the slag retaining net 30 is pulled by the cable 40.

[0042] Since one end of the cable 40 is connected to the resistance plate 50, and the resistance plate 50 is arranged downstream of the slag retaining net 30, when the water flow in the river channel increases, the potential energy of the resistance plate 50 moving downstream increases, and the end of the cable 40 is driven to pull the middle part of the slag retaining net, so as to realize the purpose of straightening the slag retaining net.

[0043] The technical solution has the advantages of simple structure, easy installation, and is more suitable for popularization and application.

[0044] In one specific embodiment:

[0045] A connecting plate 51 is also provided on the resistance plate 50, forming an L-shape with the resistance plate 50. The cable 40 is connected to the top of the end of the resistance plate 50 away from the connecting plate 51, with the connecting plate 51 facing the debris-blocking net 30. In this embodiment, by setting the connecting plate 51, the connecting plate 51 can maintain a nearly perpendicular direction to the water flow direction under the impact of the water flow in the river channel, thereby providing stronger tension for the resistance plate 50 to drive the cable 40.

[0046] Preferably, two resistance plates 50 and two connecting plates 51 are installed in the river channel, with one connecting plate 51 matching one resistance plate 50. A gap exists between the two resistance plates 50, and they are connected by a section of a cable 40. By setting up two L-shaped structures composed of connecting plates 51 and resistance plates 50, the volume of each individual resistance plate 50 and connecting plate 51 can be reduced while increasing the tension on the cable 40.

[0047] In addition, the angle between the surface of the connecting plate 51 and the surface of the resistance plate 50 is less than 90°. Therefore, when the resistance plate 50 is in a horizontal direction, the connecting plate 51 is still tilted downward and has an upward tendency. This can prevent the connecting plate 51 and the resistance plate 50 from being impacted into an inverted V-shaped structure and avoid loss of tension.

[0048] In another specific embodiment:

[0049] A support rod 21 is provided between the two support frames 20. A vertical pole 22 is provided in the middle of the support rod 21. The top of the slag-blocking net 30 is connected to the support rod 21. The middle of the slag-blocking net 30 is connected to the vertical pole 22. The end of the cable 40 is fixed to the vertical pole 22.

[0050] By setting up support rods 21, the slag-blocking net 30 can be supported, preventing excessive sagging in the middle of the net. The purpose of setting up uprights 22 is to increase the stress-bearing area of ​​the slag-blocking net 30, preventing damage from single-point stress.

[0051] Preferably, two uprights 22 are provided on the support rod 21, and there is a gap between the two uprights 22. The two uprights 22 are respectively connected to the ends of the two cables 40. By using the two uprights 22, the force-bearing surface of the cables 40 can be increased.

[0052] In addition, in this embodiment, the end of the cable 40 connected to the upright 22 has a Y-shaped structure, with the two ends of the cable 40 connected to the top and bottom of the upright 22, respectively. This structure can balance the forces on the top and bottom of the upright 22, preventing the slag-blocking net 30 from tipping over.

[0053] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
