Description

Technical Field

[0001] The utility model relates to the field of culvert gate structures, in particular to a double-filtering culvert gate structure for river regulation. Background Art

[0002] River regulation, also known as "riverbed improvement," is an engineering measure to control and improve river channels. Scour and siltation are common in natural rivers, easily causing floods and hindering water conservancy development. To address the challenges of eliminating hazards and promoting benefits, appropriate river regulation measures must be implemented, including diversion, dredging, and bank protection.

[0003] Chinese patent number CN202320663750.1 discloses a double-filtration culvert structure for river regulation, which includes: a bottom plate, support blocks integrally arranged on both sides of the bottom of the bottom plate, a cushion layer arranged at the bottom of the bottom plate and the support blocks in a shape-matched manner, a partition wall fixed on the top of the bottom plate, an inner river side and an outer river side arranged on both sides of the partition wall, a pump trough running through the partition wall, an axial flow pump fixed in the pump trough and connecting the inner river side and the outer river side, an axial flow motor connected to the axial flow pump, a first trash rack arranged on the inner river side, a second trash rack arranged on the outer river side, and mesh holes arranged in an array on the first trash rack and the second trash rack; the axial flow pump is used to draw water from the inner river side to the outer river side.

[0004] From the above, it can be seen that in addition to meeting the need to prevent cracking, the occurrence of river scouring by river water is also avoided. The water source on the inner river side is double-filtered and pumped to the outer river side, and then used for subsequent water conservancy irrigation and other purposes, thereby realizing the regulation of the inner river side of the river. However, this case still has the following shortcomings: During the filtering work of river channel regulation, since debris or garbage will move with the water flow, it is often necessary to clean and filter the water surface. When the gate opening size is controlled, the height of the water surface changes synchronously. The existing technology is usually fixed at a fixed point when filtering and cleaning, resulting in certain limitations in use.

[0005] Therefore, in order to solve the above problems, a double-filtering culvert structure for river regulation is proposed. Utility Model Content

[0006] In order to make up for the shortcomings of the existing technology and solve the problem that the height of the water surface changes synchronously with the size of the gate opening, the utility model proposes a double-filtering culvert structure for river regulation.

[0012] Preferably, a movable shaft is hinged between the two piston rods, and a driven roller is movably installed on the movable shaft.

[0022] The following will be combined with the accompanying 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.

[0023] See also Figure 1-Figure 5 As shown, a double-filter culvert structure for river regulation includes a main body 1 and a filter collection assembly 2. The filter collection assembly 2 is mounted with a mounting base 21. A stepper motor 22 is fixedly mounted on one side of the mounting base 21. A transmission shaft 23 is fixedly mounted on the output end of the stepper motor 22. A transmission roller 24 is fixedly mounted on the transmission shaft 23. A conveyor belt 25 is connected to the periphery of the transmission roller 24. A driven roller 26 is connected to the other side of the conveyor belt 25.

[0024] During operation, power is provided by the stepping motor 22, which drives the transmission shaft 23 to rotate, and the transmission roller 24 transmits power to the conveyor belt 25, which is conducive to the rotation of the conveyor belt 25 and the transportation of garbage on the water surface.

[0025] Furthermore, the main body 1 is installed with a base 11, a trash rack 12 is fixedly installed on one side of the base 11, a threaded shaft 14 is passed through one side of the base 11 and movably installed, a gate 15 is fixedly installed at the bottom of the threaded shaft 14, and a handle 13 is passed through the top of the threaded shaft 14 and threadedly connected;

[0026] During operation, through the threaded connection between the handle 13 and the threaded shaft 14, when a person rotates the handle 13, the rotational motion of the handle 13 is converted into linear motion of the threaded shaft 14, which is conducive to the movable lifting and lowering of the gate 15. The trash rack 12 prevents garbage under the water surface from passing through and performs corresponding filtering protection.

[0027] Furthermore, a mounting seat 21 is fixedly mounted on the top of the base 11, and two fixing seats 28 are fixedly mounted on the top of the base 11;

[0028] During operation, the support and positioning of the top element by the base 11 is beneficial to the overall stability during operation.

[0029] Furthermore, a filter plate 34 is fixedly mounted on one side of the mounting base 21, a placement plate 32 is fixedly mounted on the top of the base 11, and a collection hopper 33 is placed on the top of the placement plate 32;

[0030] During operation, the garbage conveyed by the conveyor belt 25 enters the collecting hopper 33 through the filter plate 34 and is collected. During operation, the water contained in the garbage is filtered through the holes opened in the filter plate 34 .

[0031] Furthermore, a hydraulic cylinder 29 is hinged to one side of each of the two fixing seats 28, and a piston rod 31 is movably mounted on the output end of each of the two hydraulic cylinders 29;

[0032] During operation, the fixed seat 28 is hinged to the hydraulic cylinder 29 so that the fixed seat 28 limits and fixes it, and at the same time, the hydraulic cylinder 29 can move in a circle with the hinge of the fixed seat 28 as the axis.

[0033] Furthermore, a movable shaft 27 is hinged between the two piston rods 31, and the movable shaft 27 passes through and is movably mounted with a driven roller 26;

[0034] During operation, the hydraulic cylinder 29 converts hydraulic energy into mechanical energy to drive the piston rod 31 to perform telescopic movement, and the piston rod 31 drives the movable shaft 27 and the driven roller 26 to perform relative movement, which is beneficial to adjusting the angle of the conveyor belt 25.

[0035] Working principle: By driving the stepper motor 22, the transmission shaft 23 at the output end is rotated, and the transmission shaft 23 drives the transmission roller 24 to cooperate with the driven roller 26, so that the conveyor belt 25 rotates accordingly, and the conveyor belt 25 is used to transport the garbage on the water surface. When the garbage is transported to a certain position, the garbage moves to one side through the filter plate 34 and moves to the inside of the collection bucket 33 for collection to filter the water surface. When the gate is opened, the water level will change accordingly with the opening size of the gate. At this time, the hydraulic cylinder 29 can be driven to make the piston rod 31 at the output end retract and retract, and one end of the piston rod 31 drives the movable shaft 27 to move, so that the conveyor belt 25 moves in a circle around the transmission roller 24 as the axis, so as to adapt to different water levels.

[0036] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
