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 that is used for oil field subsurface sampler timing sampling, be specifically related to a kind of down-hole high-temperature electronic timer.
Background technology
At present; The time that the various subsurface samplers that use in the oil field all adopt mechanical activation clock control to begin to take a sample, mechanical activation clock mainly is made up of clockwork spring, escapement, gear set, output shaft, triggering cone pulley etc., and its principle is to utilize clockwork spring to be power; Evenly discharge the clockwork spring energy through escapement; Driven gear, output shaft and the rotation of triggering cone pulley will touch the trigger mechanism on the ST when triggering when cone pulley turns to ad-hoc location, thereby make ST begin sampling.Mechanical activation clock is because the installing space restriction; Its design torque is less, timing time is shorter, owing under hot environment, use, each mechanical parts is prone to produce distortion simultaneously; Clamping stagnation occurs or stop phenomenon through regular meeting; Its design error is generally at 8-30 minutes, and error is bigger in real work, and the wearing and tearing of each mechanical parts also can have a strong impact on operate as normal after long-term the use.
Summary of the invention
Patent purpose of the present invention just provides a kind of down-hole high-temperature electronic timer, solves the defective 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; Be made up of plug, spring, shell, battery, contact, insulating mat, control circuit assembly, support, reducing motor, reset switch, time-measuring electric potential device, pilot lamp, cone pulley, it is characterized in that plug, shell, support are threaded successively, the plug center is provided with blind hole; Spring is filled in the blind hole; Support is a spill, and left end is provided with groove, and the right-hand member inboard is provided with endoporus and center small through hole; The right side is provided with screw hole, has its center, hole of three different sizes that the aperture that communicates with the inboard endoporus of right-hand member is all arranged on the right-hand member external diameter; Insulating mat is an annular, after the looping pit of contact embedding insulating mat is interior, in the groove of whole embedding support left end; Reducing motor is filled in interior its motor shaft of the inboard endoporus of support right-hand member through the center small through hole, is connected with support through screw, and the control circuit assembly is connected with the rack groove inwall through screw; Reset switch, time-measuring electric potential device, pilot lamp are respectively charged in the hole that three different sizes are arranged on the right-hand member external diameter and are glued; The cone pulley left end is have center pit and radial hole cylindrical, and right-hand member is taper and has the semilune groove, and the center pit of cone pulley is filled on the motor shaft of reducing motor and through radial hole and fixed with pin; Battery is contained between spring and the contact; Lead connects: contact right-hand member and control circuit assembly are connected to become positive pole; The control circuit assembly is connected with screw through support, shell, plug, spring and forms negative pole, and reducing motor, reset switch, time-measuring electric potential device, pilot lamp are connected with the control circuit assembly through one group lead separately respectively.
The invention has the beneficial effects as follows: accurate timing, dependable performance, output torque is bigger.
