Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of hydraulic engineering, and specifically relates to a hydraulic engineering trash screen. BACKGROUND

[0002] In hydraulic engineering, the trash screen is an important device for intercepting sundries in water flow to prevent it from entering the water conservancy facilities and causing damage or affecting the normal operation of the water conservancy facilities.

[0003] Problems existing in the prior art:

[0004] The conventional trash screen mostly adopts a fixed structure, and the grid pipe and the grid rod are usually fixedly installed, which is difficult to adapt to the dynamic change of the water level, and in the rainy season or flood period, the effective interception height of the fixed trash screen is insufficient, so that a large amount of sundries can cross the trash screen and enter the water conservancy facilities, which not only increases the difficulty of subsequent cleaning and maintenance, but also can cause equipment failure and affect the normal operation of the water conservancy project. UTILITY MODEL CONTENTS

[0005] The utility model aims at providing a hydraulic engineering trash screen, which can ensure the continuous and effective interception of sundries in water, greatly improve the adaptability of the trash screen to different water level conditions, and ensure the stable operation of the water conservancy project under various water level conditions.

[0006] The technical scheme adopted by the utility model is as follows:

[0007] A hydraulic engineering trash screen comprises a frame body, a plurality of plug-in holes are arranged in the top of the frame body in a transverse equidistant array, a grid pipe is arranged in the plug-in hole, a positioning groove for limiting the bottom of the grid pipe is arranged in the inner bottom of the frame body, a connecting hole communicating with the plug-in hole is arranged in the top of the frame body, a connecting block for limiting and fixing the top of the grid pipe is screw-connected in the connecting hole, a through hole is arranged in the top of the connecting block, a grid rod is plug-connected in the through hole, a limiting block is arranged in the grid rod and extends into the grid pipe, a mounting plate is arranged between the tops of a plurality of grid rods, a connecting pipe is fixed to the bottom of the mounting plate and screw-connected with the top of the grid rod, a plurality of detachable floating blocks are arranged on the top of the mounting plate, and a fixing mechanism capable of being adjusted up and down is arranged on the two sides of the bottom of the frame body.

[0008] The two sides of the frame body are provided with connecting ears symmetrical about the center.

[0009] A plurality of blocking rods are equidistantly arranged on the two sides of the top of the mounting plate.

[0010] The middle outer wall of the frame body and located on both sides of the grid pipe are provided with reinforcing plates.

[0011] The fixing mechanism comprises a plug-in slot formed on both sides of the bottom of the frame body, a screw rod fixed to the inner top of the plug-in slot, and a ground stake plugged into the plug-in slot, wherein an inner threaded hole matched with the screw rod is formed in the top of the ground stake, and a plurality of triangular blocks are arranged on the outer surface of the ground stake below the plug-in slot.

[0012] The utility model discloses technical effects achieved are:

[0013] The utility model discloses a linkage structure of float, mounting plate, grid rod and grid pipe, which can respond to the dynamic change of water level in real time. When the water level rises, the buoyancy of the float drives the mounting plate and the grid rod to move upwards, ensuring that the height of the trash barrier always matches the water level, effectively preventing sundries from entering the water conservancy facility through the trash barrier. When the water level drops, the float moves downwards, driving the grid rod to move downwards in the grid pipe, avoiding unnecessary exposure of the trash barrier structure, reducing resource waste while ensuring continuous and effective interception of sundries in the water. This greatly improves the adaptability of the trash barrier to different water levels, ensuring stable operation of the water conservancy project under various water levels. When it is necessary to replace damaged parts, only simple rotation of the grid rod and the connecting block is needed to quickly separate and extract the parts, without the need for complex tools and a large amount of manpower, greatly shortening the maintenance time and improving the maintenance efficiency of the water conservancy facility, reducing the impact of equipment maintenance on the normal operation of the water conservancy project.
