Abstract
The invention relates to an underground high-temperature electronic timer. The underground high-temperature electronic timer structurally consists of a plug, a shell and a bracket, which are sequentially connected. A spring is plugged into a blind hole of the plug. After a contact is embedded into an annular hole of an insulating mat, the whole insulating mat is embedded into a groove at the left end of the bracket. A speed reducing motor is plugged into an inner hole on the inner side of the left end of the bracket, and a motor shaft of the speed reducing motor is connected with the bracket through a small through hole in a center. A control circuit assembly is connected with the inner wall of the groove of the bracket. A resetting switch, a timing potentiometer and an indicator lamp are arranged into three holes with different sizes on the external diameter of the right end of the bracket respectively, are firmly adhered through an adhesive, and are connected with the control circuit assembly respectively. A center hole of a bevel pulley is plugged into the motor shaft of the speed reducing motor, and is fixed by using a pin through a radial hole. A battery is arranged between the spring and the contact. The right end of the contact is connected with the control circuit assembly to form an anode, and the control circuit assembly is connected with screws, and forms a cathode through the bracket, the shell, the plug and the spring, which are connected into a whole. The speed reducing motor is connected with the control circuit assembly. The underground high-temperature electronic timer is accurate in time, reliable in performance and high in output torque.
Description
Technical field
The present invention relates to a kind of time set for oil field well sampler timing sampling, be specifically related to a kind of down-hole high-temperature electronic timer.
Background technology
At present, the various subsurface samplers that oil field is used all adopt mechanical activation clock control to start the time of sampling, mechanical activation clock is mainly comprised of clockwork spring, escapement, gear set, output shaft, triggering cone pulley etc., its principle is to utilize clockwork spring for power, by escapement, evenly discharge clockwork spring energy, driven gear, output shaft and trigger cone pulley rotation, when triggering cone pulley and turn to ad-hoc location by the trigger mechanism touching in sampler, thereby make sampler start sampling.Mechanical activation clock is because installing space limits; its design torque is less, timing time is shorter; simultaneously owing to using under hot environment; each mechanical parts easily produces distortion; often there will be clamping stagnation or stop phenomenon; its design error is generally at 8-30 minutes, and in real work, error is larger, and after long-term use, the wearing and tearing of each mechanical parts also can have a strong impact on normal work.
Summary of the invention
Patent object of the present invention is just to provide a kind of down-hole high-temperature electronic timer, solves the defect that above-mentioned prior art exists, and improves the sampling success ratio of subsurface sampler simultaneously.
Technical scheme of the present invention is:
A kind of down-hole high-temperature electronic timer, by plug, spring, shell, battery, contact, insulating mat, control circuit assembly, support, reducing motor, reset switch, time-measuring electric potential device, pilot lamp, cone pulley, formed, it is characterized in that plug, shell, support are threaded successively, plug center is provided with blind hole, spring is filled in blind hole, support is spill, left end is provided with groove, right-hand member inner side is provided with endoporus and center small through hole, right side is provided with screw hole, has three the big or small Kong Qi of difference centers all to have the aperture communicating with endoporus inside right-hand member on right-hand member external diameter; Insulating mat is annular, after contact embeds in the looping pit of insulating mat, in the groove of embed wholly support left end; Reducing motor is filled in interior its motor shaft of endoporus of support right-hand member inner side by center small through hole, by screw, is connected with support, and control circuit assembly is connected with rack groove inwall by screw; Reset switch, time-measuring electric potential device, pilot lamp are respectively charged in the hole that has three different sizes on right-hand member external diameter and are glued; Cone pulley left end is have center pit and radial hole cylindrical, and right-hand member is taper and has semilune groove, and the center pit of cone pulley is filled on the motor shaft of reducing motor and fixed by radial hole pin; Battery is contained between spring and contact; Wire connects: contact right-hand member and control circuit assembly are connected to become positive pole, control circuit assembly is connected with screw by support, shell, plug, spring formation negative pole, and reducing motor, reset switch, time-measuring electric potential device, pilot lamp pass through respectively the wire of a group separately and be connected with control circuit assembly.
The invention has the beneficial effects as follows: accurate timing, dependable performance, output torque is larger.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
