Abstract
The invention discloses a lock limiting device of a shutter dam. The device comprises a bottom shaft (1), a gate (2) arranged on the bottom shaft and a cable (3), wherein the cable is connected with the gate; and the other end of the cable is winded with a belt wheel (4) provided with a drive device. In the lock limiting device of a shutter dam adopting the technical scheme, the drive device drives the belt wheel to rotate, and the extension length of the cable is controlled so as to control the open angle of the shutter dam; the cable can extend for any length and thus the gate can be opened at any angle; and the lock limiting device is convenient to control, has a reasonable structure and facilitates the realization of a waterfall landscape of the shutter dam.
Description
Technical field
The present invention relates to a kind of shutter dam, relate in particular to the shutter dam locking stopping means that is used to control shutter dam gate angle.
Background technology
Shutter dam in use can at this time just need use the holding in a certain position of gate and make tight stopping means for the size of controlled water flow or for the effect of making waterfall.In the prior art, the locking stopping means just can lock inconvenient operation, angular adjustment at random after in locking, needing the aligned position allocation.
Summary of the invention
Goal of the invention: the objective of the invention is to deficiency, a kind of shutter dam locking stopping means that can control the arbitrarily angled unlatching of shutter dam is provided to prior art.
Technical scheme: in order to realize the foregoing invention purpose, the technical scheme that the present invention adopted is:
A kind of shutter dam locking stopping means comprises lower shaft and the gate that is arranged at lower shaft, also comprises hawser, and described hawser is connected with gate, and the hawser other end is twining and is being provided with the belt wheel of drive unit.
Described drive unit is reductor or hydraulic means.
Described reductor is a worm-gear speed reducer.
Described hawser is a wirerope.
Beneficial effect: the present invention compared with prior art, its beneficial effect is:
1, drive unit driving pulley rotation, the length that the control hawser stretches out, thereby the angle that the control shutter dam is opened, thereby hawser can open at any angle by the random length gate, control is convenient, and is rational in infrastructure;
Advantages such as 2, drive unit is a worm-gear speed reducer, has the speed ratio height, and torsion is big; And have auto-lock function; In as the power-equipment that drives gate opening/closing, can also be used as locking device, mechanical self-latching is stable more, can the pressure loss and produce slippage.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, through a most preferred embodiment, technical scheme of the present invention is elaborated, but protection scope of the present invention is not limited to said embodiment.
As shown in Figure 1, a kind of shutter dam locking stopping means is characterized in that: comprise lower shaft 1 and the gate 2 that is arranged at lower shaft; Also comprise hawser 3; Described hawser is connected with gate, and the hawser other end is twining at the belt wheel that is provided with drive unit 4, and described drive unit is a reductor; Described reductor is a worm-gear speed reducer, and hawser 3 is a wirerope.Drive unit can also adopt hydraulic means.
Claims (4)
