[0029] Under normal circumstances, the hydraulic cylinder 3 is driven to rotate the hydraulic dam body 2 inside the dam seat 1 with the shaft center of the pin shaft as the center to achieve the action of blocking water and releasing flood. The auxiliary support mechanism realizes auxiliary support for the hydraulic dam body 2 through the steel wire rope 4, and part of the water pressure on the hydraulic dam body 2 is borne by the steel wire rope 4, thereby reducing the pressure of the hydraulic dam body 2 on the hydraulic cylinder 3, so as to achieve the effect of auxiliary support for the hydraulic dam body 2. The tension sensor 5 is arranged to realize real-time detection of the tension between the steel wire rope 4 and the hydraulic dam body 2. When the water pressure on the tension sensor 5 rises to the set upper limit value, the tension sensor 5 feeds back the detection value to the control center of the whole device, and the control center controls the hydraulic cylinder 3 and the auxiliary support mechanism to act. At this time, the hydraulic dam body 2 needs to be deflected by the hydraulic cylinder 3 to realize drainage pressure reduction, and the auxiliary support mechanism realizes pay-off of the steel wire rope 4 to ensure that the hydraulic dam body 2 can be deflected. Conversely, when the hydraulic dam body 2 is in the water blocking state and the water pressure on the tension sensor 5 is lower than the set lower limit value, the auxiliary support mechanism realizes take-up of the steel wire rope 4 at this time, so that the steel wire rope 4 is in a taut state, and the auxiliary support for the hydraulic dam body 2 is realized through the steel wire rope 4.

[0030] The auxiliary support mechanism comprises a driving shaft 42 and a supporting shaft 43 which are horizontally installed in the mounting seat through bearings, the driving shaft 42 and the supporting shaft 43 are arranged in parallel with each other, a plurality of driving gears 44 are fixedly sleeved on the driving shaft 42 at intervals, each driving gear 44 is engaged with a transmission gear 45 on the supporting shaft 43, the cooperation of the driving gear 44 and the transmission gear 45 enables the supporting shaft 43 to rotate at a uniform speed, a plurality of winding wheels 46 are also fixedly sleeved on the supporting shaft 43, one end of the steel wire rope 4 is wound on the winding wheel 46, in order to provide a driving source for the auxiliary support mechanism, the auxiliary support mechanism further comprises a supporting motor 41 for providing a driving source for the auxiliary support mechanism, in order to realize stable tensioning of the steel wire rope 4 on the hydraulic dam body 2, the supporting motor 41 of the present application adopts a supporting motor 41 with self-locking performance, and the output shaft of the supporting motor 41 is fixedly connected with one end of the driving shaft 42 through a shaft coupling.

[0031] By setting the auxiliary support mechanism, the hydraulic dam body 2 is achieved to realize the effect of auxiliary support, control support motor 41 rotation, support motor 41 will be converted into mechanical energy, drive gear 44 and transmission gear 45 meshing, drive shaft 43 and support shaft 43 surface winding wheel 46 with the shaft of the support shaft 43 as the center of rotation, through the support motor 41 forward and reverse to realize the action of the steel wire rope 4, and then to realize the effect of auxiliary support of the hydraulic dam body 2.

[0032] In order to realize the steel wire rope 4 auxiliary hydraulic cylinder 3 to the hydraulic dam body 2 to realize the action of low speed, drive gear 44 and transmission gear 45 meshing, the number of teeth of drive gear 44 and transmission gear 45 is 10:1, in the process of flood discharge, under the impact of water pressure, the surface of the hydraulic dam body 2 force increases greatly, it is easy to cause the hydraulic dam body 2 collapse, in order to avoid the occurrence of this phenomenon, the application is through the use of the number of teeth of drive gear 44 and transmission gear 45, the steel wire rope 4 auxiliary hydraulic cylinder 3 to the hydraulic dam body 2 to realize the action of low speed, and then greatly prolong the service life of the hydraulic cylinder 3, the outer surface of the support shaft 43 is fixed with winding wheel 46 for winding the steel wire rope 4, the upper surface of the hydraulic dam body 2 is provided with mounting groove, the inner wall of the mounting groove is fixedly connected with the mounting rod 47, the outer surface of which is fixedly connected with the steel wire rope 4, through the cooperation of the mounting groove, the mounting rod 47, the steel wire rope 4 and the winding wheel 46, the steel wire rope 4 has the advantages of high stability and good safety during auxiliary support of the hydraulic dam body 2.

[0033] The middle part of the hydraulic dam body 2 is provided with a drainage mechanism, and the surface of the hydraulic dam body 2 at the front end of the drainage mechanism is also provided with a water power generation mechanism.

For example, heavy rainfall occurs in a short time, resulting in a sharp increase in upstream water volume. At this time, the hydraulic dam body 2 will be overloaded. At this time, the hydraulic dam body 2 is deflected to realize drainage and flood discharge by the hydraulic cylinder 3. It is impossible to immediately solve the overloading of the hydraulic dam body 2. When the tension sensor 5 detects that the tension of the steel wire rope 4 reaches the alarm value, the drainage mechanism is controlled to open to realize rapid drainage and pressure relief. Furthermore, when the hydraulic dam body 2 or the hydraulic cylinder 3 fails, the drainage and pressure relief cannot be realized by the deflection of the hydraulic dam body 2. At this time, the drainage and pressure relief can be realized by the drainage mechanism. By setting the water power generation mechanism, the effect of water power generation of the water flow discharged by the drainage mechanism is achieved.

[0035] The hydraulic cylinder 3 is the main supporting component of the hydraulic dam body 2, and if the hydraulic cylinder 3 is in a fully extended state for a long time, the load of the hydraulic cylinder 3 is large and the service life is short.

When the water flow is drained, the following two conditions must be met: one is that the tension sensor 5 detects that the tension between the steel wire rope 4 and the hydraulic dam 2 is greater than the set value; the second is that the water flow enters the electrically conductive cavity 65 from the water inlet 66, under the action of water pressure, the water flow extrudes the lower electrically conductive sheet 68, so that the lower electrically conductive sheet 68 slides upward along the electrically conductive cavity 65 and contacts the upper electrically conductive sheet 67, at this time the power supply circuit of the drainage motor 64 is connected.
