Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a river sluice device used in water conservancy projects. Background Art

[0002] Sluice gates are low-head hydraulic structures built on rivers and canals that use gates to control flow and regulate water levels. Closing the gates can prevent flooding, block tides, or raise upstream water levels to meet water needs for irrigation, power generation, shipping, aquaculture, environmental protection, industry, and domestic use. Opening the gates allows floodwater, waterlogging, abandoned water, or wastewater to be discharged, or water can be supplied to downstream rivers or canals. Sluice gates are widely used in water conservancy projects as structures for retaining, releasing, or extracting water. Currently, when sluice gates are in use, garbage from upstream often drifts to the vicinity of the gates, polluting the environment and easily being carried downstream by the current.

[0003] The Chinese patent publication number CN219195856U discloses a river sluice device for water conservancy projects. The device can block garbage upstream of the river through the cooperation of gate piers, interception frames, filter nets, collection frames and collection nets, and further collect the intercepted garbage, realizing garbage collection at the gate.

[0004] However, it is extremely laborious to lift the filter net and the collection net of the above structure out of the water due to the existence of water resistance, which can easily cause the filter net and the collection net to deform. Especially when the river channel is wide, the span of the collection net is large, and the contact area with the water is increased, resulting in greater water resistance. At this time, it is not easy to remove the garbage in the middle of the collection net after salvage, which brings a burden to the staff. Utility Model Content

[0023] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1 - Figure 6 The utility model discloses a river sluice device for water conservancy projects, including a base 1, a pier 2 and a gate 4. The gate 4 can be raised and lowered on the pier 2, and also includes a filter screen 7. The filter screen 7 is arranged upstream of the gate 4, and the two ends of the filter screen 7 are respectively fixed to the inner side of the pier 2. The filter screen 7 is an arc-shaped structure to guide the impurities on the filter screen 7 to move toward the two ends of the filter screen 7 under the impact of water flow. The filter screen 7 with an arc structure can not only intercept garbage on the water surface, but also make the garbage drift to the two sides of the pier 2 along the arc edge of the filter screen 7 after being impacted by the water flow, so as to facilitate the staff to salvage it.

[0025] In addition, in order to prevent upstream silt from flowing out with the water flow and causing the downstream riverbed to rise, the river sluice device for the water conservancy project provided in this embodiment also includes a sand retaining dike 18. The sand retaining dike 18 is fixed on the base 1 and is located downstream of the gate 4. The side of the sand retaining dike 18 facing the gate 4 is a sloped structure to block the silt at the bottom of the water flow. Preferably, the sand retaining dike 18 is a concrete structure. Through the setting of the sand retaining dike 18, the silt at the bottom of the water flow is blocked and accumulated on the slope side of the sand retaining dike 18, thereby avoiding the downstream river channel from being blocked and the riverbed rising due to the impact of silt, thereby improving the practicality of the equipment.

[0026] As the silt accumulates on the inclined side of the sand retaining dike 18, it will slide to the bottom of the sand retaining dike 18 under the influence of gravity. In order to prevent the silt from accumulating here and affecting the discharge of the gate 4, the river sluice device for the water conservancy project provided in this embodiment also includes a slag discharge component. The slag discharge component is arranged between the gate 4 and the sand retaining dike 18 to discharge the silt between the sand retaining dike 18 and the gate 4. Through the setting of the slag discharge component, the accumulated silt can be discharged from the river channel, which is conducive to keeping the river channel unobstructed.

[0027] like Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 and Figure 6 As shown, in order to prevent the surface filter 7 from being deformed by the impact of water flow, the river sluice device for the water conservancy project provided in this embodiment also includes a support plate 17. The support plate 17 is fixed to the upper surface of the base 1, and one side of the support plate 17 is against the middle section of the filter 7. Preferably, the support plate 17 is a triangular structure to improve its supporting effect.

[0028] In order to further prevent the filter screen 7 from deformation, the river sluice device for the water conservancy project provided in this embodiment also includes ribs 20, which are arranged at equal intervals on both sides of the support plate 17 for supporting the filter screen 7. Auxiliary plates bolted to the ribs 20 are installed at equal intervals on the other side of the filter screen 7 for fixing the filter screen 7. In this solution, the ribs 20 and the auxiliary plates are both arc-shaped structures, and the curvature is the same as that of the filter screen 7, so as to better clamp and fix the filter screen 7.

[0029] like Figure 3 - Figure 5 As shown, in order to improve the sealing effect after the gate 4 is closed and avoid water leakage, the river sluice device for the water conservancy project provided in this embodiment also includes a limit plate 16, which is fixed on the base 1. The side of the limit plate 16 facing the filter screen 7 is a slope structure for guiding the flow of water, and the side of the limit plate 16 facing the gate 4 is a square structure, such as a rectangular structure, and its side close to the gate 4 is perpendicular to its upper surface to form a step-shaped structure, so that the sealing path of the gate 4 when closing is extended, thereby improving the sealing effect. In addition, the limit plate 16 is fixedly connected to the lower end of the support plate 17 to improve the stability of the support plate 17.

[0030] In addition, a contact plate 5 is provided on the outer side of the gate 4 near the lower end. When the gate 4 is closed, the lower surface of the contact plate 5 abuts against the upper surface of the limit plate 16, thereby improving the sealing effect of the gate 4 after closing and reducing water leakage.

[0031] like Figure 1 - Figure 4 As shown, in order to improve the stability of the gate 4 during its movement, the river sluice device for the water conservancy project provided in this embodiment also includes a limiting chute 3, which is opened on the inner side of the gate pier 2, and the limiting chute 3 is slidably connected to the side of the gate 4 for traction when the gate 4 is raised or lowered.

[0032] In addition, an inclined plate 19 is fixed on the upper surface of the base 1, and the inclined plate 19 is located between the two limiting slide grooves 3. The maximum height of the inclined plate 19 is less than the maximum height of the limiting plate 16. The bottom of the gate 4 is a sloped structure. When the gate 4 is closed, the gate 4 is engaged with the inclined plate 19. Through the inclined contact, the contact area between the gate 4 and the inclined plate 19 is increased, thereby extending the sealing path and improving the sealing effect.

[0033] like Figure 1 As shown, in order to facilitate the installation of the filter screen 7, fixed piles 6 are installed on both sides of the filter screen 7, and the fixed piles 6 are fixedly connected to the gate pier 2. In this solution, salvage parts can also be set at the fixed piles 6 to salvage garbage at the gate pier 2.

[0034] like Figure 2 - Figure 4 As shown, the slag discharge component provided in this embodiment includes a slag discharge channel 8, which is fixed on the base 1, and a through groove is provided at the middle section of the slag discharge channel 8 between the sand retaining dike 18 and the gate 4. Both ends of the slag discharge channel 8 pass through the outside of the gate pier 2, and one end of the slag discharge channel 8 is a closed structure and the other end is an open structure. When too much sediment accumulates on the inclined side of the sand retaining dike 18, the sediment slides to the through groove under its own gravity, and then enters the inside of the slag discharge channel 8.

[0035] Furthermore, the slag discharge assembly provided in this embodiment also includes a driven shaft 14, which is rotatably installed inside the slag discharge channel 8, and an auger blade 15 adapted to the slag discharge channel 8 is provided on the outside of the driven shaft 14, and leakage holes are evenly provided on the surface of the auger blade 15, and the pitch of the auger blade 15 gradually decreases from the closed structure to the open structure of the slag discharge channel 8. In this solution, the auger blade 15 is driven to rotate by the driven shaft 14, and the auger blade 15 is used to push the mud and sand inside the slag discharge channel 8 to move, and the mud and sand are discharged from the opening structure. In this process, the pitch of the auger blade 15 is gradually reduced, so that the extrusion during the mud and sand output process can be achieved, thereby reducing the water content in the mud and sand and improving the practicality of the equipment. It should be noted that the slag discharge channel 8 is provided with an opening and closing valve near the opening structure to control the opening and closing of the slag discharge channel 8.

[0036] like Figure 1 - Figure 4 As shown, in order to realize the driving of the driven shaft 14, a driving shaft 11 is rotatably installed between the two gate piers 2 at a position above the sand retaining dike 18, and water wheels 13 are arranged at equal intervals on the driving shaft 11. One end of the water wheel 13 passes through the gate pier 2 and is installed with a driving wheel 12, and one end of the driven shaft 14 passes through the slag discharge channel 8 and is installed with a driven wheel 9. A synchronous transmission belt 10 is provided between the driven wheel 9 and the driving wheel 12. In this scheme, when the water flows through the water wheel 13, it will drive the water wheel 13 to rotate, and the water wheel 13 drives the driving shaft 11 to rotate, further causing the driving wheel 12 to rotate, and the driven shaft 14 is rotated through the transmission action between the driving wheel 12, the driven wheel 9 and the synchronous transmission belt 10.

[0037] The working principle and use process of the utility model are as follows: when the gate 4 is opened, the water flows quickly through the gate pier 2 and intercepts the garbage on the water surface through the arc-shaped filter screen 7. With the continuous impact of the water flow, the garbage will drift along the arc edge of the filter screen 7 to the two sides of the gate pier 2, which is convenient for the staff to salvage. After passing through the gate 4, the water flow collides with the sand retaining dike 18. The setting of the sand retaining dike 18 blocks the sediment at the bottom of the water flow and accumulates on the inclined side of the sand retaining dike 18, avoiding the downstream river channel from being blocked and the riverbed rising due to the impact of sediment, thereby improving the practicality of the equipment. When too much sediment accumulates on the inclined side of the sand retaining dam 18, the sediment slides to the through groove due to its own gravity, and then enters the slag discharge channel 8. During this process, water flows through the water wheel 13 and drives the water wheel 13 to rotate. The water wheel 13 drives the driving shaft 11 to rotate, and further rotates the driving wheel 12. The transmission action between the driving wheel 12, the driven wheel 9 and the synchronous transmission belt 10 causes the driven shaft 14 to rotate, and the driven shaft 14 drives the auger blades 15 to rotate, and the auger blades 15 push the sediment inside the slag discharge channel 8 to move, and the sediment is discharged from the opening structure.
