Description

Technical Field

[0001] This utility model relates to the field of sluice gate opening and closing technology, specifically a sluice gate opening and closing device for U-shaped channels. Background Technology

[0002] According to domestic and international research data, except for low flow rates where the hydraulically optimal cross-section of a trapezoidal channel requires less lining work than a U-shaped channel, U-shaped channels generally require less lining work than trapezoidal or rectangular channels. Therefore, U-shaped channels should be widely promoted for farmland irrigation. Furthermore, U-shaped channels are very common in final-stage irrigation channels, not only because they occupy less land, have good flow characteristics, and strong flow capacity, but also because they are less prone to siltation and resistant to frost heave.

[0003] To control the water flow in U-shaped channels, gate chambers and gates are often installed within the channels. Water flow is controlled by opening and closing the gates. However, after the gates are closed to cut off the flow, a large amount of garbage, branches, and other debris accumulates in front of the gates over time. When the gates are opened, this debris flows downstream, affecting the quality of the subsequent water flow. For example, during agricultural irrigation, the debris may enter reservoirs or flow directly into farmland, degrading the farmland environment. Therefore, before opening the gates to release water, staff usually need to clean the debris in front of the gates. This process is not only ineffective but also consumes a lot of manpower. Utility Model Content

[0004] The purpose of this utility model is to provide a sluice gate opening and closing device for U-shaped channels to solve the problems existing in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sluice gate opening and closing device for a U-shaped channel, comprising a gate, a gate plate, a motor, and a winch, and further comprising:

[0006] The fixing plates are fixed on both sides of the back of the gate plate. The fixing plates have T-shaped grooves inside. The back of the gate plate is provided with a scooping plate. T-shaped blocks are fixed above and below the surface of the scooping plate. The surface of the T-shaped blocks is movably connected to the inside of the T-shaped groove.

[0007] A mounting plate is fixed to the surface of the gate, and a vertical plate is fixed to the top of the mounting plate. An oil storage tank is fixed to the other end of the vertical plate. A pull rod is movably connected inside the oil storage tank. A piston is fixed to one end of the pull rod. An oil outlet pipe is connected to the bottom of the oil storage tank. A folded tube is connected to the other end of the oil outlet pipe.

[0008] Preferably, a limiting pin is provided through the top of the fixing plate, and the other end of the limiting pin passes through the T-shaped block and extends into the interior of the fixing plate.

[0009] Preferably, the surface of the oil outlet pipe is provided with a solenoid valve, and the solenoid valve is located above the folded pipe.

[0010] Preferably, the surface of the oil storage tank is provided with an observation window.

[0011] Preferably, the other end of the pull rod is movably connected to the interior of the mounting plate, and a pull ring is fixedly connected to the other end of the pull rod.

[0012] Preferably, handles are fixed at both the top and bottom of the left side of the scooping plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, through the setting of the scooping plate, can intercept debris and garbage on one side of the gate. As the gate is raised, the scooping plate will move along with it, thus facilitating the scooping of debris and garbage. This can prevent debris from being discharged randomly after the gate is opened. At the same time, through the movable connection between the surface of the T-shaped block and the inside of the T-shaped groove, the scooping plate can be pulled out to facilitate the subsequent cleaning of debris and garbage inside the scooping plate.

[0015] 2. After repeated use, the steel wire rope wound on the surface of the winch in this utility model will cause the piston to move along with the downward force of the pull rod, thereby squeezing the lubricating oil inside the oil reservoir. This allows the lubricating oil to be discharged along the oil outlet pipe and the folded pipe, so as to facilitate the lubrication of the steel wire rope. Attached Figure Description

[0022] 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.

[0023] Please see Figure 1-5 As shown, a sluice gate opening and closing device for a U-shaped channel includes a gate 1, a gate plate 2 movably connected inside the gate 1, a motor 3 fixed to the top of the gate 1, a winch 4 bolted to the output shaft of the motor 3, and a steel wire rope wound around the surface of the winch 4, with the other end of the steel wire rope fixed to the top of the gate plate 2. Fixing plates 5 are fixedly connected to both sides of the back of the gate plate 2, and T-slots 6 are formed inside the fixing plates 5. A scooping plate 7 is provided on the back of the gate plate 2, and T-blocks 8 are fixed above and below the surface of the scooping plate 7. The surface of the T-blocks 8 is movably connected to the interior of the T-slots 6. A mounting plate is fixedly connected to the surface of the gate 1. The plate 11 is mounted on a vertical plate 12, and an oil reservoir 13 is fixed to the other end of the vertical plate 12. An observation window 9 is provided on the surface of the oil reservoir 13, so that the amount of lubricating oil inside the oil reservoir 13 can be easily observed through the observation window 9. A pull rod 14 is movably connected inside the oil reservoir 13. A piston 15 is fixed to one end of the pull rod 14. An oil outlet pipe 16 is connected to the bottom of the oil reservoir 13. A folded tube 17 is connected to the other end of the oil outlet pipe 16. A solenoid valve 18 is provided on the surface of the oil outlet pipe 16, and the solenoid valve 18 is located above the folded tube 17, so that the lubricating oil inside the oil reservoir 13 can be closed.

[0024] A limiting pin 10 is provided through the top of the fixing plate 5, and the other end of the limiting pin 10 passes through the T-shaped block 8 and extends into the interior of the fixing plate 5. This can fix the position of the scooping plate 7 and prevent the scooping plate 7 from sliding out at will.

[0025] The other end of the pull rod 14 is movably connected to the interior of the mounting plate 11, and a pull ring 19 is fixedly connected to the other end of the pull rod 14. This not only provides auxiliary support for the pull rod 14, but also makes it convenient to apply force to pull the pull rod 14.

[0026] Handles 20 are fixed on the upper and lower sides of the left side of the scooping plate 7. After the gate plate 2 rises, the scooping plate 7 can be pulled to facilitate the dumping of debris and garbage inside the scooping plate 7.

[0027] It is worth noting that the technical features proposed in this technical solution should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be selected using conventional methods in the field. This technical solution will not elaborate further.

[0028] Working principle: During use, as the gate 2 closes the U-shaped channel, debris and garbage in the channel will be located behind the gate 2, allowing the scooping plate 7 to intercept them. When the gate 2 is opened, the motor 3 is started, driving the winch 4 to rotate, which in turn moves the gate 2 upward. As the gate 2 rises, the scooping plate 7 moves along with it, thus scooping up the debris and garbage at the scooping plate 7. After the debris and garbage are scooped up, the limit pin 10 can be pulled out, and then the scooping plate 7 can be pulled out from the side. This facilitates the dumping of debris and waste inside the scooping plate 7. After dumping, the T-block 8 can be slid back into the fixed plate 5 and re-fixed by the limit pin 10. After the wire rope on the surface of the winch 4 has been used multiple times, the solenoid valve 18 can be activated and the pull rod 14 can be pulled down, thereby driving the piston 15 to squeeze the lubricating oil inside the oil reservoir 13, so that the lubricating oil can be sprayed onto the wire rope along the oil outlet pipe 16 and the folded pipe 17, thereby facilitating lubrication and improving the service life of the wire rope.
