Detailed Description
For the purpose of facilitating understanding by those skilled in the art, two aspects of the invention will be described in further detail below with reference to the drawings and specific examples.
Scheme one embodiment of the reverse linkage type turnover gate:
as shown in fig. 1-7, the clearance of the lock chamber 1 is 2.0m, the height of the upper gate 2 is 2.2m, the height of the lower gate 3 is 2.3m, the height of the notch 24 is 0.5m, the width is 0.9m, the length of the cantilever 23 is 1.0m, and the length of the '1' -shaped connecting rod 41 is 0.84m; the height from the upper rotating shaft to the gate bottom is 2.4m, and the distance from the upper rotating shaft to the gate plate is 0.12m; the height from the lower rotating shaft to the gate bottom is 0.89m, and the distance from the lower rotating shaft to the gate plate is 0.12m; the total weight of the gate is 1550kg. When the upstream water depth rises from 4m to 4.5m, the comprehensive moment of the gate is increased from-582 kgm to 360kgm, which proves that the gate is stable when being erected and reliable when being overturned.
Preferably, the lock chamber side wall 11 is cast in place by reinforced concrete, and the upper rotating shaft 21, the lower rotating shaft 31 and the buffer base 61 are pre-embedded on the side wall 11.
Preferably, the upper shaft 21 and the upper sleeve 22 are made of steel and nylon. The lower shaft 31 and the lower sleeve 32 are made of stainless steel and nylon materials.
Preferably, the upper gate 2, the lower gate 3, the cantilever 23, the "1" type connecting rod 41, the upper shaft sleeve 22 and the lower shaft sleeve 32 are manufactured in a factory, and are made of steel materials. The cantilever 23 is welded or riveted to the upper gate.

Further, the upper gate 2 may be further provided with a hydraulic device to actively control the rotation of the gate.
The working procedure in one embodiment of the scheme is as follows:
in a non-flood period, when the water inflow is small, the upper gate 2 and the lower gate 3 are erected for retaining water, the water level fluctuates up and down at the position of the notch 24 most of the time, and the residual water overflows from the notch, so that the comprehensive overturning moment of the upper gate 2 and the lower gate 3 is a negative value; in the flood period, the inflow water flow is increased, the water level is increased, the comprehensive overturning moment of the upper gate 2 and the lower gate 3 is increased, when the water level exceeds the set value, the gates lose balance, the upper gate 2 and the lower gate 3 simultaneously rotate in a linkage manner, and the flood is automatically overturned to the downstream and the upstream respectively.
Because the lower gate overturns upstream against water flow, the water resistance can slow down the gate overturning speed and reduce the gate impact force. When the gate is overturned and contacts the limiting buffer piece 6, the impact force of the gate is further reduced under the buffer action of the spring steel plate 62 and the rubber pad 63, and the gravity and viscous force of water can inhibit the elastic jump of the gate.
After flood, when the flow of the incoming water is reduced, the gate is pulled up by a manual hoist and a movable support to erect water again.
The above embodiment is a preferred implementation manner of the different direction linkage type tilting gate according to the present invention, and is not limited in any way, and any simple modification, equivalent replacement, improvement, etc. according to the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.

When the upstream water depth rises from 2.3m to 2.6m, the comprehensive moment (friction is not counted) of the gate increases from-49.3 kgm to 55.8kgm, which shows that the gate is stable when being erected and reliable when being overturned.
Preferably, the second sluice chamber side wall 11 is cast in situ by reinforced concrete, and the upper rotating shaft 21, the lower rotating shaft 31 and the buffer base 61 are pre-embedded on the side wall 11.
