Abstract
The utility model provides a micro-motor miniature variable-speed hydroturbine speed governor which comprises a driving part, a transmission part and an output part. The driving part comprises a miniature motor and a reducer. The transmission part is provided with a ball bearing screw pair. The output shaft of the reducer is connected with the screw rod of the ball bearing screw pair by a bearing. The nut of the ball bearing screw pair is connected with an output device which comprises a slide sleeve which is mounted outside the nut and is connected with the nut and an output rod which is connected with the tail end of the slide sleeve. The external wall of the slide sleeve is provided with a guide key and a guide base which is matched with the guide key. The utility model does not require the pressure oil operation and a mechanical hydraulic pressure component and has simple structure and convenient maintenance, so a plurality of troubles during the operation and the maintenance are avoided, which is convenient for wide personnel at the hydropower station of the country to learn. The utility model prevents the disadvantage caused by the screw thread seizure and has high reliability and good maintainability.
Description
Technical field
The utility model relates to a kind of micro motor speed change small hydraulic turbine speed regulator, especially for the small hydraulic turbine speed regulator of rural area small hydroelectric power station.
Background technique
In the past, domestic and international small-sized speed regulator was all imitated big-and-middle-sized speed regulator, and many complex mechanisms need be set, as oil gear, electricity-liquid or electricity-machine conversion equipment, with main servomotor, mechanical cabinet and the regulator cubicle of pressure oil operation ...Particularly mechanical-hydraulic partly, the hydraulic pressure components and parts are many, complex structure, the maintenance trouble for the vast small hydropower station in rural area, owing to can't guarantee the absolute turbidity test of oil, often takes place that hydraulic parts stops up, the jam fault, the manual operation of having to change into that has.
Electricity-liquid the converting member that can regulate continuously again highi degree of accuracy, as electrohydraulic control, electro-hydraulic proportional servo valve etc.,, safeguard hell to pay because of it is too high to oily turbidity test requirement, power station, China rural area few use the to the utmost, and commonly used being substituted by the stronger Solenoid ball valve of inexpensive oil rub resistance ability.But this mode only can be carried out the adjusting of switch type, though regulation quality is relatively poor, but still can satisfy the requirement of power station, rural area.And this hydraulic system of being made up of the switch type Solenoid ball valve be unable to do without the pressure oil-source operation, so still more complicated, trouble.Before a lot of years, the scheme that excessive motor directly drives the trapezoidal screw pair of sliding once occurred, and, removed already and abandon owing in servicely the fault that screw thread is killed often occurs.
Summary of the invention
The purpose of this utility model is that a kind of motor forward and backward of design can realize the open and close machine, does not need hydraulic system, can prevent the disadvantage that thread biting locking brings and the micro motor speed change small hydraulic turbine speed regulator of trouble.
The technical solution of the utility model: micro motor speed change small hydraulic turbine speed regulator of the present utility model comprises drive part, drive part, output, drive part comprises miniature motor and retarder, drive part adopts ball spiral pair, reducer output shaft is connected with the leading screw of ball spiral pair by bearing, and the nut of ball spiral pair is connected with output unit; Output unit comprises and is enclosed within the outer and sliding sleeve that is attached thereto of nut, the take-off lever that is connected with the sliding sleeve tail end have feather key to reach the guide holder of cooperation with it on the sliding sleeve outer wall.
Advantage of the present utility model: this device does not need mechanical-hydraulic partly without the pressure oil operation, and is simple in structure, easy to maintenance, thereby the trouble when saving many operating maintenances, be convenient to vast rural hydropower station personnel and grasp, be a kind of new-type small hydraulic turbine speed regulator that is worthy to be popularized.Prevented the disadvantage that thread biting locking brings, no matter in reliability, maintenance, structure and in price, this programme has incomparable superiority.For vast village small station, can realize auto-parallel, automatic load and the quick emergency shutdown regulated.In addition, also have easy hand and grasp mechanism, can realize black the startup and manually-operable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Fig. 1 is a structural representation of the present utility model: micro motor speed change small hydraulic turbine speed regulator of the present utility model comprises drive part, drive part, output.
Drive part comprises miniature motor 1 and retarder 2, drive part adopts ball spiral pair, the output shaft 2.1 of retarder 2 is connected with the leading screw 6 of ball spiral pair by bearing 4, and bearing 4 is installed in the bearing support 3, and the nut 7 of ball spiral pair is connected with output unit; The nut 7 of the ball spiral pair sliding sleeve 9 outer with being enclosed within nut 7 is connected by bolt 8, and sliding sleeve 9 tail ends are connected with take-off lever 10, has feather key 9.1 to reach the guide holder 9.2 of cooperation with it on sliding sleeve 9 outer walls.The 12nd, frame, the 14th, basis seat, the 13rd, stone bolt.Guide holder 9.2 is fixed on the frame 12, and the 5th, hand behaviour mechanism.Leading screw 6 afterbodys of ball spiral pair are equipped with Comprehensive Control piece 11, play the location and prevent thread biting locking.
Retarder 2 adopts the cycloidal planetary gear speed reducer of standard B series.BWD-17 (velocity ratio) joins 0.75KW (input power) miniature motor, and the reducer output shaft moment of torsion is 75NM, and output speed is 88 rev/mins.Adopting the helical pitch of FFZD6320-5 type ball spiral pair is 20mm, so displacement take-off lever per second can be walked 29.33mm, can realize 5.1 seconds quick emergency shutdowns.Adopt gear shift mode to satisfy the normal regulating burden requirement.
The efficient of ball spiral pair is generally 0.9, and (or drawing) power that pushes away that calculates this device displacement take-off lever is greater than 2000kgf.The speed governing merit is greater than 300kgfM when stroke 150mm.
Utilize miniature motor (stepper motor, interchange or DC servo motor, torque motor or various common electric machine) forward and backward, add high pulling torque through speed reducer (gear type, planetary gear type, worm gear type, humorous wave mode or various speed reducer), moving through the transhipment of ball spiral pair mutarotation again is straight-line displacement, with the Kai Heguan of operation turbine gate mechanism.
