Description
[technical field]
The utility model relates to a kind of small hydropower station intake gate control valve unit, particularly a kind of small hydropower station water inlet gate valve DC controlled device.
[background technique]
The water inlet gate valve of medium waterpower generator station controls to be generally Non-follow control, AC Motor Control in the market.The shortcoming of these control modes is:
1, in medium waterpower generator station, many water inlet gate valves are had all not install electric controller, manually can only carry out switch water inlet gate valve by runner, when generator contactor accident causes tripping operation or generator to turn maintenance, staff manually must close water inlet gate valve by runner, and the shut-in time of water inlet gate valve often reaches a few minutes, staff compares effort, and efficiency is lower.
2, AC Motor Control is on original hand wheel, adds that exchanges a control motor.When system dead electricity, load rejection, the power supply controlling motor disappears or maintains the very short time, gate valve pass to full off state, can not have potential safety hazard.
[summary of the invention]
Technical problem to be solved in the utility model is to provide a kind of small hydropower station water inlet gate valve DC controlled device, and it is easy for installation, price is suitable, good stability, high safety.
The utility model is achieved in that
A kind of small hydropower station water inlet gate valve DC controlled device, comprises direct current generator, the first gear, the 3rd gear, the 3rd gear, the first chain, the second chain, mounting plate, position limit switch, gear disk;
Described mounting plate is fixedly mounted on described water inlet gate valve; Described gear disk is fixed on described water inlet gate valve runner screw rod; Described first gear, the second gear are fixedly mounted on described direct current generator;
Described first chain is around in the periphery of described gear disk and described first gear;
Described 3rd gear is fixedly mounted on described position limit switch;
Described direct current generator and described position limit switch are arranged on mounting plate respectively; Described second chain is around in the periphery of described second gear and described 3rd gear.
The utility model has the advantage of: flexibility is high: this DC controlled device can carry out customization processing according to water power plant gate valve of intaking, and only need carry out machine rebuilding to its gate valve of intaking according to tested shape; Good reliability: the position limit switch of this DC controlled device Installation of New Type, fully open position and closed positions can accurately be located, and prevent excessive switch; High safety: this DC controlled device adopts direct current 24V Energy control, in system dead electricity, during generator tripping removal of load, can emergency cut-off water inlet gate valve.
[accompanying drawing explanation]
The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is the utility model plan view.
Fig. 2 is the utility model plan view.
Fig. 3 is the utility model side view.
[embodiment]
As shown in Figure 1 to Figure 3, a kind of small hydropower station water inlet gate valve DC controlled device, comprises direct current generator 1, first gear 2, first chain 3, second chain 4, mounting plate 5, position limit switch 6, gear disk 7, second gear 9, the 3rd gear 8.
Described mounting plate is fixed 5 and is arranged on described water inlet gate valve; Described gear disk 7 is fixed on described water inlet gate valve runner screw rod; Described first gear 2 and the second gear 9 are fixedly mounted on described direct current generator 1.
Described first chain 3 is around in the periphery of described gear disk 7 and described first gear 2.
Described 3rd gear 8 is fixedly mounted on described position limit switch 6;
Described direct current generator 1 and described position limit switch 7 are arranged on mounting plate 5 respectively;
Described second chain 4 is around in the periphery of described second gear 9 and described 3rd gear 8.
Gear disk 7 is fixed on described water inlet gate valve runner screw rod, utilizes the first chain 3 driven gear dish 7, and then allows water inlet gate valve runner screw rod rotate, and promotes the Kai Heguan of water inlet gate valve.
Direct current generator 1 is fixedly mounted on mounting plate 5, and power line is connected to clockwise and anticlockwise motor module, by changing the direction of power supply, allows direct current generator 1 clockwise and anticlockwise.
First gear 2 is fixed in same level with gear disk 7.
Position limit switch 6 is fixedly mounted on mounting plate 5, make the 3rd gear 8 on position limit switch 6 and the second gear 9 on direct current generator 1 in same level by the mounting point of adjustment stroke switch 6 and link together with the second chain 4, the spacing travel point determining water inlet gate valve of adjustment position limit switch 6.
By controlling this direct current generator 1, can automatically open and close water inlet gate valve.Owing to being adopt direct current 24V to power, only needing to provide the storage battery of two joint 12V namely to can be direct current generator 1 provides power supply, for the safe operation in whole water power plant provides safeguard.
The utility model overcomes the shortcomings such as Non-follow control efficiency is low, alternating current controlled is unreliable.Flexibility is high: this DC controlled device can carry out customization processing according to water power plant gate valve of intaking, and only need carry out machine rebuilding to its gate valve of intaking according to tested shape; Good reliability: the position limit switch of this DC controlled device Installation of New Type, fully open position and closed positions can accurately be located, and prevent excessive switch; High safety: this DC controlled device adopts direct current 24V Energy control, in system dead electricity, during generator tripping removal of load, can emergency cut-off water inlet gate valve.
Above-described embodiment and graphic and non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field, to its suitable change done or modification, all should be considered as not departing from patent category of the present utility model.
