Description
Technical field
the present invention relates to a kind of gyroscope north searching instrument, particularly the motor electric supply installation and the method for supplying power to of gyroscope north searching instrument.
Background technology
gyroscope north searching instrument; Claim meridian gyro or gyrocompass again; It is a freely-suspended gyropendulum; Usually the inside of metal hang spring suspension that is made by a constant modulus alloy is equipped with the rotor case body of gyro motor, constitutes a free gyro that receives gravity constraint and do not have other friction in suspension.Under the effect of earth rotation horizontal component, the gyro rotation motor axis of rotation has the ability of the local meridian direction of trend.Gyroscope north searching instrument and transit are combined, and gyroscope north searching instrument is put on the shelf in transit, can measure the direct north of certain point.Therefore, gyroscope north searching instrument is usually used in measuring on the ore deposit, purposes such as tunnel holing through, positioning and directing measurement.In the prior art,, need external power source be flowed to the inner gyro motor driving circuit of rotor case with the many flexible fluid-directing silks that specific alloy is made usually for to the gyro motor power supply.The electric current that the water conservancy diversion silk self can bear, the requirement when making it can not satisfy the gyro motor startup.But because gyrostatic principle of work does not allow to use the water conservancy diversion silk that can bear bigger working current again.For this reason, some systems adopt the power supply contact parallelly connected with the water conservancy diversion silk to add great start-up current.When gyro motor starts, need current ratio bigger, bear electric current bigger when starting jointly by water conservancy diversion silk and power supply contact, and make electric current most of through power supply contact, prevent to burn the water conservancy diversion silk; After gyro motor arrived rated speed, electric current was reduced in the scope that the water conservancy diversion silk can bear, and breaks off power supply contact this moment, thereby by water conservancy diversion silk power supply beginning surveying work separately.Take the weak point of the electric supply installation of this structure to be: when the contact resistance of power supply contact during greater than water conservancy diversion silk resistance, can burn the water conservancy diversion silk equally, the reliability of gyroscope north searching instrument is relatively poor.
Summary of the invention
technical matters to be solved by this invention is the deficiency that overcomes prior art, and a kind of improved gyroscope north searching instrument is provided.
the present invention also will provide a kind of method of supplying power to of above-mentioned gyroscope north searching instrument simultaneously.
are for solving the problems of the technologies described above; A kind of technical scheme that the present invention adopts is: a kind of gyroscope north searching instrument; It comprises housing, is arranged on freely-suspended gyropendulum, outer cover, eyepiece system and objective system in the housing, and said gyropendulum comprises rotor case body and the motor that is arranged in the rotor case body, and said gyroscope north searching instrument also comprises the electric supply installation that is used for to the motor power supply; This electric supply installation comprises external power source, many water conservancy diversion silks that are electrically connected with external power source, the power supply contact parallelly connected with the water conservancy diversion silk; Particularly, described electric supply installation also comprises and the corresponding respectively relay that connects so that the water conservancy diversion silk is protected of each water conservancy diversion silk, this relay be arranged so that supply current at needs is more than or equal to water conservancy diversion silk bearing value the time; The water conservancy diversion silk is broken from feed circuit;, and at the supply current of needs during, that the water conservancy diversion silk is parallelly connected with power supply contact by power supply contact less than water conservancy diversion silk bearing value separately to motor power supply.
The another technical scheme that
the present invention takes is: a kind of method of supplying power to of motor of above-mentioned gyroscope north searching instrument, when motor starting, break off by relay control water conservancy diversion silk, and supply power to motor separately by power supply contact; After motor reaches rated speed, logical by the wire connection of relay control water conservancy diversion, make the water conservancy diversion silk parallelly connected, and then break off power supply contact with power supply contact, separately to the motor power supply, this moment, gyroscope north searching instrument began surveying work by the water conservancy diversion silk.
Because adopt the enforcement of above technical scheme, the present invention compared with prior art has following advantage:
gyroscope north searching instrument according to the present invention increases the relay that the water conservancy diversion silk is protected in the motor electric supply installation, thereby prevents that effectively the water conservancy diversion silk from burning because of electric current is excessive, guarantees the gyroscope north searching instrument reliability.
The motor method of supplying power to of gyroscope north searching instrument of the present invention is taked in
, and the security of water conservancy diversion silk is good, and difficult quilt burns, the gyroscope north searching instrument good reliability; Prevent operator's maloperation simultaneously.
Description of drawings
are done further detailed explanation below in conjunction with accompanying drawing and concrete embodiment to the present invention.
Fig. 1 is the structural representation according to gyroscope north searching instrument of the present invention;
Fig. 2 is the circuit diagram according to motor electric supply installation of the present invention;
wherein: 1, housing; 2, gyropendulum; 20, rotor case body; 21, motor; 3, outer cover; 4, eyepiece system; 5, objective system; 6, water conservancy diversion silk; 7, power supply contact.
Embodiment
like Fig. 1, and gyroscope north searching instrument generally includes housing 1, be arranged in the housing 1 freely-suspended gyropendulum 2, outer cover 3 and accessory for example eyepiece system 4 and objective system 5.Gyropendulum 2 comprises rotor case body 20 and is arranged at the motor 21 in the rotor case body 20.Said gyroscope north searching instrument also comprises the electric supply installation that is used for to motor 21 power supplies.The present invention relates generally to the improvement to the electric supply installation of motor 21.
referring to Fig. 1 and Fig. 2, and gyroscope north searching instrument motor electric supply installation comprises many water conservancy diversion silks 6, the power supply contact 7 parallelly connected with water conservancy diversion silk 6 and is connected the relay 8 on each water conservancy diversion silk 6.The main effect of relay 8 is to control water conservancy diversion silk 6 according to the size of required supply current to be switched on or switched off from feed circuit.Specifically, when motor 21 started, required electric current was bigger, and at this moment, relay 8 control water conservancy diversion silks 6 break off, and are supplied power to motor 21 separately by power supply contact 7; After motor 21 reached rated speed, required electric current was less, was lower than the bearing value of water conservancy diversion silk 6; This moment, relay 8 control water conservancy diversion silks 6 were connected, and made it parallelly connected with power supply contact 7, broke off power supply contact 7; Separately to motor 21 power supplies, be beneficial to reduce electric energy loss, saves energy by water conservancy diversion silk 6.
More than the present invention has been done detailed description; Its purpose is to let the personage that is familiar with this art can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences of doing according to spirit of the present invention change or modify, and all should be encompassed in protection scope of the present invention
