Description

Technical Field

[0001] This utility model relates to the field of sluice gate device technology, and in particular to a segmented sluice gate structure for dams. Background Technology

[0002] A sluice gate is a low-head hydraulic structure built on rivers and canals to control flow and regulate water levels. When the gate is closed, it can block floods, tides, or raise the upstream water level to meet the needs of irrigation, power generation, navigation, aquaculture, environmental protection, industrial and domestic water use. When the gate is opened, it can release floodwater, floodwater, wastewater, or wastewater, and can also supply water to downstream rivers or canals. In water conservancy projects, sluice gates serve as structures for blocking, releasing, or taking in water.

[0003] In the process of realizing this application, the inventors discovered the following problems in the prior art: Currently, most existing traditional sluice gates use a single gate structure to control the water flow in the river. Due to the heavy weight of the gate itself, and after bearing the horizontal thrust generated by the difference in water levels between upstream and downstream, the motor is prone to excessive power consumption when lifting the gate, which can lead to motor damage. Therefore, those skilled in the art have provided a segmented sluice gate structure for dams to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a segmented sluice gate structure for dams. After combining and splicing the first gate body, the second gate body and the third gate body, the pressure on the gate body during lifting can be effectively reduced. The dual-axis servo motor can better drive the gate body to adjust its height. The rotating wheel can guide the cable and reduce friction loss. The fixed shell with snap-fit ​​can protect the dual-axis servo motor.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A segmented sluice gate structure for dams includes a fixed plate, with mounting brackets fixedly installed on both sides of the lower end face of the fixed plate. Sliding rods are fixedly embedded on the front end of the opposite side of the two mounting brackets. A first gate body is installed between the two mounting brackets at the upper end. A second gate body is installed on the lower end face of the first gate body. A third gate body is installed on the lower end face of the second gate body.

[0007] A dual-axis servo motor is snapped into place at the midpoint of the upper surface of the fixed plate. A drive shaft is fixedly installed on both output ends of the dual-axis servo motor. A winding wheel is installed on one side of the outer surface of each of the two drive shafts, and a cable is wound around the outer surface of each of the two winding wheels.

[0008] Furthermore, the two winding wheels are respectively fixedly sleeved on one end of the outer surface of the two drive shafts, and the lower ends of the two cables are respectively snapped and fixed on both sides of the upper surface of the third gate body.

[0009] Furthermore, the second gate body is movably embedded inside the lower end face of the first gate body, and the third gate body is movably embedded inside the lower end face of the second gate body.

[0010] Furthermore, the first gate body, the second gate body, and the third gate body are respectively movably embedded on one side of the two mounting brackets, and the two cables respectively pass through the upper surfaces of the first gate body and the second gate body.

[0011] Furthermore, limit blocks are snapped into the midpoints of both sides of the upper surface of the first gate body. The two limit blocks are movably embedded in the upper part of one side of the two mounting brackets, and the two limit blocks are movably sleeved on the outer surface of the two slide rods.

[0012] Furthermore, multiple rotating wheels are provided on both sides of the lower end face and both sides of the upper end face of the fixing plate, and four of the rotating wheels located on the same side are respectively attached to the outer surfaces of the two cables.

[0013] Furthermore, a fixed outer shell is snapped onto the upper surface of the fixed plate, and snap-fit ​​brackets are snapped onto the upper sides of both mounting brackets.

[0014] This utility model has the following beneficial effects:

[0015] 1. The present invention proposes a segmented sluice gate structure for dams. By setting a first gate body, a second gate body, and a third gate body between two mounting frames, the weight of the gate body can be effectively reduced. When the dual-axis servo motor is used to lift the gate body, overload damage to the dual-axis servo motor can be effectively avoided. At the same time, after setting a sliding rod on the upper side of one side of the two mounting frames, it can be movably connected with a limit block, so that the first gate body can be lifted better between the two mounting frames. Meanwhile, after the third gate body is opened, the pressure on the gate body can be reduced, making the sluice gate work better.

[0016] 2. The present invention proposes a segmented sluice gate structure for dams. By fixing multiple rotating wheels on the upper and lower surfaces of the fixed plate, the wheels can be attached to the cables fixed on the upper surface of the third gate body, thereby guiding the cables and preventing them from contacting the fixed plate and causing wear. After setting a snap-fit ​​bracket on one side of the mounting frame, the gate body can be better installed and fixed in a suitable position on the dam. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figures 1 to 5 A segmented sluice gate structure for dams includes a fixed plate 3, with mounting brackets 2 fixedly installed on both sides of the lower end face of the fixed plate 3. Sliding rods 13 are fixedly embedded on the opposite side of the two mounting brackets 2 near the front end. A first gate body 4 is installed between the two mounting brackets 2 near the upper end. A second gate body 5 is installed on the lower end face of the first gate body 4. A third gate body 6 is installed on the lower end face of the second gate body 5.

[0026] A dual-axis servo motor 9 is snapped onto the midpoint of the upper surface of the fixed plate 3. A drive shaft 10 is fixedly installed on both sides of the output end of the dual-axis servo motor 9. A winding wheel 11 is installed on one side of the outer surface of the two drive shafts 10. Cables 12 are wound around the outer surface of the two winding wheels 11.

[0027] Specifically, after mounting brackets 2 are installed on both sides of the lower end face of the fixed plate 3, the first gate body 4, the second gate body 5, and the third gate body 6 can be movably embedded between the two mounting brackets 2, so that the gate body can be lifted between the two mounting brackets 2. After the slide rod 13 is fixedly installed at the upper end between the two mounting brackets 2, the first gate body 4, which has a limit block 14 attached to its upper end face, can be sleeved between the two slide rods 13, so as to limit the first gate body 4 and effectively prevent the first gate body 4 from being over-adjusted. After the dual-axis servo motor 9 is installed on the upper end face of the fixed plate 3, the drive shaft 10 can be fixedly installed on both output ends of the dual-axis servo motor 9. At the same time, after the take-up wheel 11 is fixed on the outer surface of the two drive shafts 10, the cable 12 can be wound on the outer surface of the take-up wheel 11. After one end of the cable 12 is fixedly connected to the upper end face of the third gate body 6, the dual-axis servo motor 9 can drive the third gate body 6 to move and lift.

[0028] Reference Figure 3 and Figure 4 Two winding wheels 11 are fixedly sleeved on one end of the outer surface of the two drive shafts 10, and the lower ends of the two cables 12 are respectively clamped and fixed on both sides of the upper surface of the third gate body 6.

[0029] Specifically, after the take-up reel 11 is fixedly sleeved on the outer surface of the drive shaft 10, the dual-axis servo motor 9 can better drive the take-up reel 11 to rotate synchronously through the drive shaft 10. After the lower end of the cable 12 is fixedly connected to the upper end of the third gate body 6, the synchronously rotating take-up reel 11 can lift the third gate body 6. At the same time, a bearing seat is provided at the end of the drive shaft 10 away from the dual-axis servo motor 9. After the bearing seat is connected to the drive shaft 10, the drive shaft 10 can better drive the take-up reel 11 to rotate.

[0030] Reference Figure 5 The second gate body 5 is movably embedded inside the lower end face of the first gate body 4, and the third gate body 6 is movably embedded inside the lower end face of the second gate body 5.

[0031] Specifically, after the second gate 5 is movably embedded inside the first gate 4 and the third gate 6 is movably embedded inside the second gate 5, when the third gate 6 is lifted, the third gate 6 embedded inside the second gate 5 can drive the second gate 5 to be lifted. At the same time, the first gate 4 can also be lifted under the drive of the embedded second gate 5, so that the third gate 6 can better drive the second gate 5 and the first gate 4 to be lifted.

[0032] Reference Figure 4The first gate body 4, the second gate body 5 and the third gate body 6 are respectively movably embedded on one side of the two mounting brackets 2, and the two cables 12 pass through the upper surfaces of the first gate body 4 and the second gate body 5 respectively.

[0033] Specifically, by movably embedding the first gate body 4, the second gate body 5, and the third gate body 6 between the two mounting brackets 2, the gate bodies can be lifted and moved more effectively between the mounting brackets 2. Furthermore, by passing the cable 12 through the upper surfaces of the first gate body 4 and the second gate body 5, the cable 12 can better drive the third gate body 6 to be lifted.

[0034] Reference Figure 4 Limiting blocks 14 are snapped into the midpoints of both sides of the upper end face of the first gate body 4. The two limiting blocks 14 are respectively movably embedded in the upper end of one side of the two mounting brackets 2, and the two limiting blocks 14 are respectively movably sleeved on the outer surface of the two sliding rods 13.

[0035] Specifically, after the limit block 14 is fixed by bolts on both sides of the upper end face of the first gate body 4, the first gate body 4 can be better embedded in the upper part between the two mounting brackets 2. After the limit block 14 and the slide rod 13 are movably connected, the lifting height of the first gate body 4 can be limited.

[0036] Reference Figure 3 Multiple rotating wheels 7 are provided on both sides of the lower end face and both sides of the upper end face of the fixing plate 3. Four of the rotating wheels 7 located on the same side are respectively attached to the outer surface of the two cables 12.

[0037] Specifically, after multiple rotating wheels 7 are set on both sides of the upper end face and both sides of the lower end face of the fixing plate 3, they can fit together with the cables 12 that pass through both sides of the fixing plate 3. This allows the rotating wheels 7 to guide the cables 12, thereby effectively preventing the cables 12 from contacting the fixing plate 3 and causing wear on the cables 12.

[0038] Reference Figure 1 and Figure 2 The upper end of the fixed plate 3 is fitted with a fixed outer shell 1, and the upper ends of the two mounting brackets 2 are fitted with clip brackets 8.

[0039] Specifically, after the outer shell 1 is fixed by bolts on the upper end of the fixing plate 3, the fixing shell 1 can protect the dual-axis servo motor 9 and effectively prevent rainwater from damaging the motor. After the clamping frame 8 is installed and fixed on both sides of the mounting frame 2 by bolts, the sluice gate can be better installed and fixed in a suitable position on the dam. The mounting frame 2 has multiple threaded grooves on one side near the upper end, which can better adjust the position of the clamping frame 8.

[0040] Working principle: During use, the operator can use bolts to adjust the two clamping brackets 8 to the appropriate position, thereby installing and fixing the sluice gate in the dam. When the sluice gate needs to be used, the dual-axis servo motor 9 can be started, causing the cable 12 to drive the third gate body 6 to lift. After the third gate body 6 and the second gate body 5 are fully engaged, the second gate body 5 can be driven to engage with the first gate body 4, thereby effectively lifting and adjusting the first gate body 4, the second gate body 5 and the third gate body 6, and at the same time, better controlling the flow of water in the dam.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
