Abstract
The utility model relates to a radio digital transmission electronic well head motor, which is composed of a cable magnetic making apparatus 1, a signal processing circuit 2, a radio digital transmission circuit 3, a transmitting antenna 4, a cable depth photoelectric encoder 5, a bevel gear 6, a driving shaft 7, a driving gear 8 and a microgenerator 9, wherein, the photoelectric encoder is directly connected with the driving shaft of the driving gear to convert a rotary angle signal of the gear into an electric pulse signal. The cable magnetic marking apparatus records a magnetic signal on an armoured oil field cable. The two signals are changed into digital signals after magnification, shaping, filtering and signal acquisition. The digital signals which are sent to a transmitting circuit are transmitted by radio waves in a digital coding mode. The construction technique of the existing well head logging device is simplified. Cable wires do not need connecting, the damage of connecting wires, the poor contact of a socket, and easy aging embrittlement and damage of rubber are stopped, and the radio digital transmission electronic well head motor is not limited by construction yards. As the transmitting power of a radio digital transmission device is small, interference for other radio equipment can not be caused, and the utility model has the advantages of long service life and no pollution.
Description
The utility model relates to a kind of oil reservoir logging construction well head parameter measuring apparatus, particularly wireless data sending electronic well head motor.
Existing machinery well head motor is by the rotational angle of well head pulley, Y-connection coil rotor through selsyn, three groups of sinusoidal simulating signals that output is relevant, drive the driven selsyn of user side by a multi-core cable wire, drive photoelectric encoder, for miscellaneous equipment provides angle information, realize the transmission of rotational angle signal; The simulating signal of oil field cable magnetic mark device output simultaneously also passes on the magnetic mark dash receiver through this cable, owing to be wired formula, there are contact, the cable ageing of rubber that open-air cold causes breakage, winter at the construction field (site) of the edge connector problems such as cracky that become fragile, failure rate height during construction, labour intensity is big.
The purpose of this utility model is to provide a kind of wireless data sending electronic well head motor, does not need cable to be connected between well head motor and the instrument truck, realizes the measuring-signal digitizing, the transmission signals wireless penetration, reduced volume, weight reduction, simplify working process, improve the reliability of well head motor.
The purpose of this utility model is to realize like this, it is by cable magnetic mark device (1), signal processing circuit (2), wireless digital transmission circuit (3), emitting antenna (4), cable depth photoelectric encoder (5), umbrella tooth (6), transmission shaft (7), transmission gear (8), microgenerator (9) is formed, transmission gear (8) and transmission shaft (7), umbrella tooth (6), cable depth photoelectric encoder (5), signal processing circuit (2), wireless digital transmission circuit (3), emitting antenna (4) connects successively, microgenerator (9) is connected on the umbrella tooth (6), and cable magnetic mark device (1) is connected with signal processing circuit (2).
The wireless data sending electronic well head motor is that photoelectric encoder directly is connected with the transmission shaft of transmission gear, the rotational angle signal of gear is become electric impulse signal, magnetic signal on the cable magnetic mark device record armouring oil field cable, become digital signal after the amplification of two paths of signals process, shaping, filtering, the signals collecting, send radiating circuit to pass through radio wave transmission in the numerical coding mode, the radio receiver of logging instrumentation car or reel truck offers the engineering staff after receiving, and utilizes the microgenerator of self to provide electric energy for this device simultaneously.
The utility model is owing to adopted photoelectric encoder directly to be connected with the transmission shaft of transmission gear, simplified the construction technology of existing Review of Operating Devices for Logging, without the stube cable line, stop the breakage of line, the loose contact of edge connector, the ageing of rubber cracky that becomes fragile, and be not subjected to the restriction of construction site; Because the emissive power of wireless digital transmitting device is less, receive coverage less than 300 meters, to other wireless device can not cause interference, long service life, pollution-free, be well suited for applying.
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is further specified.
As shown in the figure, the utility model is made up of cable magnetic mark device 1, signal processing circuit 2, wireless digital transmission circuit 3, emitting antenna 4, cable depth photoelectric encoder 5, umbrella tooth 6, transmission shaft 7, transmission gear 8, microgenerator 9.The detected depth signal pulse of pick-up unit, magnetic mark are delivered to signal processing circuit, the wireless digital transmission circuit is launched after the encoded software of digital signal after handling is packed, the wireless digital receiving trap of logging instrumentation car and reel truck receives, to the data decoding, send respective handling and demonstration.Microgenerator provides electric energy for whole wireless data sending electronic well head motor.Owing to adopt the wireless digital transmission, the address code of each emission, receiving trap is unique, because the working-yard close together causes interference each other, saves channel resource in the time of can preventing the well logging construction.
