Technical Field

[0001] This utility model relates to the field of trash racks, and more particularly to a trash rack support structure for pumped storage power stations. Background Technology

[0002] Pumped storage power stations are a special type of hydroelectric power station. When there is an overflow of electricity, water can be pumped to store the water source. When there is a shortage of electricity, the water source is released to generate electricity. In order to prevent debris in the water from being carried into the power station channel and causing repeated damage during pumping and energy storage and power generation, trash racks are usually installed at the inlets of the upper and lower reservoirs of the pumped storage power station to block debris.

[0003] When installing trash racks, it is generally necessary to first install two sets of support frames at the installation point, and then install the trash rack at the front end of the support frames. The multiple sets of support frames are usually separated from each other, which can easily lead to gaps between the multiple sets of support frames, resulting in poor overall trash racking capacity. To address this, a trash rack support structure is proposed, which can be used to meet the trash racking requirements of the upper and lower reservoir inlets of pumped storage power stations.

When the two sets of mounting brackets 1 are in contact with each other, the two sets of mounting brackets 1 can be fastened together by using bolts to pass through the two sets of connecting plates 41.

[0033] Working principle: When installing the trash rack, first adjust the angle of intersection between the two sets of hinge rods 2 according to actual needs. Before adjustment, pull the telescopic rod 51 to drive the insertion rod 54 out of the positioning groove 53. Then, the position of the hinge rod 2 can be changed by sliding the sliding sleeve 52, thereby adjusting the distance between the two sets of mounting brackets 1. When the sliding sleeve 52 moves to the appropriate position, the telescopic rod 51 can be released. The fixing spring 55 will pull the telescopic rod 51 to drive the insertion rod 54 into the positioning groove 53, fix the sliding sleeve 52, and thus fix the distance between the two sets of mounting brackets 1.

[0034] When multiple devices need to be connected, the two devices should first be placed horizontally side by side. Then, pull the slider 43 at the rear end of the right device to move the connecting block 45 at its bottom upward. Then, push the insert block 42 to move it to the left and insert it into the groove 46 at the rear end of the left device. Then, release the slider 43. At this time, the connecting spring 44 will push the slider 43 downward to move the connecting block 45 into the connecting groove 47. At this time, the insert block 42 will be fixed and cannot move left or right. At the same time, the baffle 48 slides on the top of the telescopic rod 51 to prevent debris from entering the telescopic rod 51. In this way, the two devices are connected. After multiple mounting brackets 1 are connected to each other, the multiple mounting brackets 1 are fastened together by using bolts through the connecting plate 41 to further increase the sealing of the connection between the mounting brackets 1.
