A kind of combined floodgate interlock, this combined floodgate interlock comprises the blocking arm rotating with the semiaxis that closes a floodgate in high-voltage operating mechanism, and with the interlocking connecting lever of output shaft rotation in high-voltage operating mechanism, there is following interaction relation between connecting lever in blocking arm and interlocking: when high-voltage operating mechanism is during in "on" position, the location status that output shaft rotation reaches connecting lever end and the blocking arm one side restriction blocking arm that offsets that makes to interlock rotates, and limits combined floodgate semiaxis and rotates; When high-voltage operating mechanism is during in gate-dividing state, the location status that output shaft rotation reaches make to interlock connecting lever end and blocking arm one side removed and offseted, and removes the limit rotation of combined floodgate semiaxis; The combined floodgate semiaxis of high-voltage operating mechanism is connected with the reduction torsion spring resetting for self.Its structural feature is that coaxial connection of described interlocking connecting lever and output shaft is relative limit rotation, and between interlocking connecting lever and output shaft, be provided with the back-moving spring that both is relatively rotated to laggard horizontal reset, the maximum reset elastic force of this back-moving spring is less than the reseting elasticity of described reduction torsion spring; When described interlocking connecting lever end and described blocking arm sidepiece offset restriction blocking arm while rotating, described interlocking connecting lever under action of reset spring with respect to output shaft rotation a positive stop end to both rotation-limited strokes.By adopting above-mentioned combined floodgate interlock, in the time that blocking arm interferes with interlocking connecting lever, rely on relatively rotating and back-moving spring between interlocking connecting lever and output shaft, and the elastic force of combined floodgate reduction torsion spring that semiaxis connects is greater than the elastic force of back-moving spring, can automatically terminate the interference that offsets of blocking arm and interlocking connecting lever, the interlocking that effectively prevents from closing a floodgate lost efficacy, and improved the reliability of the interlocking that closes a floodgate.
According to such scheme, a kind of concrete structure of interlocking connecting lever and output shaft is: described interlocking connecting lever is provided with the annular block set with output shaft pivot bush unit, this annular block set side face is provided with the spring base of a projection, and with this spring base the arc slide opening on same circumferencial direction, rotary limited between interlocking connecting lever and output shaft is passed described arc slide opening and is fixedly connected with output shaft by screw, between the head cap position of screw and described spring base, be connected back-moving spring, under initial condition, interlocking connecting lever remains on a positive stop end of both rotation-limited strokes under action of reset spring with output shaft.
This combined floodgate interlock prevents that the method that interlocking lost efficacy from being: switched to by separating brake in the process of combined floodgate at high-voltage operating mechanism, when combined floodgate semiaxis does not reset in time and blocking arm end and interlocking connecting lever one side are offseted, be that blocking arm and interlocking connecting lever form while interference, because the reseting elasticity of reduction torsion spring is greater than the maximum reset elastic force of back-moving spring, therefore reduction torsion spring drives combined floodgate semiaxis to reset, blocking arm drives interlocking connecting lever with respect to output shaft rotation; Remove and offset after interference when blocking arm turns to the connecting lever of interlocking, blocking arm, combined floodgate semiaxis complete reset under reduction torsion spring effect, interlocking connecting lever spinning reduction relative to output shaft under action of reset spring, automatically terminates interference between blocking arm and interlocking connecting lever, realizes the interlocking that closes a floodgate.
The utility model structure is comparatively simple, interlocks comparatively reliable, is not prone to the problem that interlocking lost efficacy, and fail safe is good, and the combined floodgate interlock that is suitable as high switch operation mechanism uses, or the architecture advances of like product.

Embodiment
Now by reference to the accompanying drawings, the utility model will be further described.
As shown in Figure 1 and Figure 2, this combined floodgate interlock comprises the blocking arm 101 being connected with combined floodgate semiaxis 1 in high-voltage operating mechanism, and the interlocking connecting lever 3 being connected with output shaft 2 in high-voltage operating mechanism.Specifically being connected to of interlocking connecting lever and output shaft: interlocking connecting lever is provided with the annular block set of socket output shaft, the side face of annular block set is provided with the spring base 301 of a projection, and with this spring base the arc slide opening 302 on same circumferencial direction, be fixedly connected with output shaft through this arc slide opening by a screw 5, realize the rotation-limited of output shaft and interlocking connecting lever.Between the head cap position of above-mentioned spring base and screw, be connected a back-moving spring 4, under initial condition, interlocking connecting lever remains on a positive stop end of both rotation-limiteds under action of reset spring with output shaft.
Interaction relation between interlocking connecting lever and blocking arm is: when high-voltage operating mechanism is in the time closing a floodgate, as shown in Figure 1, the location status that output shaft reaches connecting lever end and the blocking arm one side restriction blocking arm rotation that offsets that makes to interlock, limiting combined floodgate semiaxis rotates, realize the interlocking that closes a floodgate, after preventing from closing a floodgate, again close a floodgate.When high-voltage operating mechanism is during in separating brake, as shown in Figure 2, the location status that output shaft reaches connecting lever end and blocking arm one side that makes to interlock is removed and is offseted, and interlocking connecting lever is not interfered the rotation of blocking arm, now, rotate combined floodgate semiaxis and can carry out closing operation.In the time that high-voltage operating mechanism switches to "on" position by gate-dividing state, if combined floodgate semiaxis fails after closing operation to reset in time or homing action specific output axle rotates slow completing, there will be the situation shown in Fig. 3, blocking arm end offsets to form with interlocking connecting lever one side and interferes.The appearance of this situation will cause interlocking to lose efficacy for prior art, but for the utility model, can automatically terminate by the following technical solutions this kind of interference state.
