Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy fence trash racks, in particular to a water conservancy fence trash rack with a lifting function. Background Art

[0002] Trash racks are frame-type structures installed in front of the water inlet to block water plants, driftwood and other debris carried by the water flow. Trash racks can be arranged in a straight line or a semicircular folded line on the plane, and can be upright or inclined on the facade, depending on the nature, amount, application requirements and cleaning methods of the waste carried by the water flow. The water inlet of the dam-type hydropower station with a higher head is usually upright and semicircular; the water inlet gate, hydraulic tunnel and water pipeline are mostly straight.

[0003] At present, in the existing technology, most of the hydraulic trash racks do not have the function of autonomously adjusting the height. When a large amount of sewage suddenly flows into the river, causing the water level of the river to rise, ordinary hydraulic trash racks cannot effectively intercept the dirt in the sewage. In view of this, we propose a hydraulic trash rack with a lifting function. Utility Model Content

[0004] The main purpose of the utility model is to provide a water conservancy fence trash rack with a lifting function, which can solve the problems raised in the above technical background.

[0005] In order to achieve the above-mentioned purpose, the utility model proposes a hydraulic fence trash rack with lifting function, comprising a device body, the bottom surface of which is provided with a blocking device, and the blocking device comprises:

[0006] An inner railing, one end of the inner railing is rotatably connected to the bottom surface of the device body, the other end of the inner railing is fixedly connected to one end of a tension spring, the other end of the tension spring is fixedly connected to the inner wall of the outer railing, the surface of the inner railing is slidably connected to the inner wall of the outer railing, and the end surface of the outer railing is fixedly connected with a sealing strip.

[0007] Preferably, a storage groove is provided on the surface of the inner railing, and the inner wall of the inner railing is rotatably connected to a cutting blade via a coil spring.

[0008] Preferably, the bottom surface of the outer railing is rotatably connected to the upper surface of the mounting plate, the inner wall of the mounting plate is slidably connected to the surface of the movable plate, a sliding groove is provided on the surface of the movable plate, and a cylinder is fixedly connected to the side of the movable plate.

[0009] Preferably, the inner wall of the sliding groove is slidably connected to the surface of the transmission rod, and the end surface of the transmission rod is fixedly connected to the bottom surface of the outer railing.

[0010] Preferably, the device body comprises a mounting frame, the inner wall of the mounting frame is snap-fitted to the surface of a fixing plate, and the bottom surface of the fixing plate is rotatably connected to the upper surface of the inner railing.

[0011] Preferably, a mounting buckle is fixedly connected to the side of the mounting frame, and a float is clamped on the inner wall of the mounting buckle. Beneficial Effects

[0012] The utility model provides a water conservancy fence trash rack with lifting function. It has the following beneficial effects:

[0013] (1) The hydraulic trash rack with lifting function has a float. When water flows through the trash rack, if the water level is high, the water flow lifts the float, so that the float pushes the inner railing to extend out of the outer railing, so that the blocking device can better block the garbage in the water, and the cutting blade releases the restriction of the outer railing on the cutting blade, thereby cutting the mesh garbage in the water.

[0014] (2) The hydraulic trash rack with lifting function has a movable plate. When the blocking device needs to be opened, the cylinder pushes the movable plate forward, and the sliding groove of the movable plate pushes the transmission rod to move, so that the transmission rod pushes the outer railing to rotate, so that the outer railing rotates and opens. When the blocking device needs to be closed, the cylinder pushes the movable plate backward, and the sliding groove of the movable plate pulls the transmission rod to move, so that the transmission rod pulls the outer railing to rotate, so that the outer railing rotates and closes, so that the blocking device can be opened and closed in time.
