Description

Technical Field

[0001] The utility model relates to the technical field of reservoir drainage, in particular to a novel drainage device for a reservoir. Background Art

[0002] Hydraulic gates are mostly used in places such as reservoirs and rivers to close and open drainage channels. They can also be used to intercept water flow, control water levels, regulate flow, discharge silt and floating objects, etc.

[0003] In the prior art, some small reservoir gates are generally lifted by screws, which are driven by a motor in the gate chamber above the gate. When the reservoir is filled with water for a long time, the gate is lowered and the screw is exposed to the outside. The screw is easily rusted when exposed to a humid environment for a long time. If the gate cannot be opened in time when it is urgently needed to release water, it is easy to cause a flood. Therefore, it is necessary to design a new type of reservoir drainage device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-3A novel drainage device for a reservoir comprises two gate slots 1, the upper ends of the two gate slots 1 are fixedly connected with a cross beam 4, a driving motor 5 is arranged on the cross beam 4, a threaded rod 16 is fixedly connected to the output shaft of the driving motor 5, a gate plate 2 is arranged on the threaded rod 16, a protective mechanism for protecting the threaded rod 16 is arranged under the cross beam 4, the protective mechanism comprises a mounting frame 11 fixedly connected to the lower end of the cross beam 4, a stud screw 12 is arranged on the mounting frame 11, two sliding plates 10 are arranged on the stud screw 12, the side wall of the sliding plate 10 is slidably connected with the inner wall of the mounting frame 11, so that when the stud screw 12 rotates, the sliding plate 10 will not rotate with it, and the side walls of the two sliding plates 10 are provided with protective covers 7.

[0022] A driving mechanism for driving the double-headed screw 12 to rotate is disposed on the side wall of the mounting frame 11 . The driving mechanism includes a fixed connection to the second motor 18 . One end of the double-headed screw 12 close to the second motor 18 is fixedly connected to the output shaft of the second motor 18 .

[0023] In this embodiment, a rain shield 17 is fixedly connected to the side wall of the installation frame 11 to protect the second motor 18 from rain erosion. The upper end of the rain shield 17 is provided with an inclined surface.

[0024] In this embodiment, both gate slots 1 are provided with a winch 3, which is connected to a movable beam 9 through a rope. A movable beam 9 is commonly provided in the two gate slots 1, and a plurality of crushing rollers 8 are provided on the movable beam 9. A mounting frame 14 is provided on the movable beam 9, and a first motor 15 is provided on the mounting frame 14. The first motor 15 has its own rainproof component.

[0025] In this embodiment, sprockets 13 are provided on the side walls of the plurality of crushing rollers 8, and chains are provided on the plurality of sprockets 13, so that a first motor 15 can drive the plurality of crushing rollers 8 to rotate, without the need for each crushing roller 8 to be connected to a driving device.

[0026] In this embodiment, the side walls of the two gate slots 1 are fixedly connected with the slide rails 6, and the movable beam 9 is slidably connected to the slide rails 6, so that the movable beam 9 can move along the slide rails 6 without deviation.

[0027] When in use, the double-headed screw 12 can be rotated first, so that the two sliding plates 10 move toward each other so that the two protective covers 7 are closed on both sides of the threaded rod 16, thereby sealing and protecting the threaded rod 16, preventing the threaded rod 16 from being easily rusted due to long-term exposure to a humid environment, so that the gate plate 2 can be opened and water can be released in time when the gate needs to be opened for long-term flood control;

[0028] In addition, in cold weather, when the water surface is frozen or branches are piled up at the gate, the first motor 15 can be driven, and the output shaft of the first motor 15 drives the crushing roller 8 to rotate. The crushing roller 8 drives the other multiple crushing rollers 8 to rotate through the sprocket 13 chain. The two winches 3 lower the movable beam 9 to allow the crushing roller 8 to crush the ice surface and broken branches, so that the gate will not be very difficult to lift due to the accumulation of ice and branches.

[0029] The above is only a preferred specific implementation method of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the utility model according to the technical solution and practical concept of the utility model, which should be covered by the protection scope of the utility model.
