Abstract

The invention provides an active control interconversion system for kinetic energy of a moving part and elastic potential energy of a spring. The active control interconversion system for kinetic energy of the moving part and elastic potential energy of the spring is that the kinetic energy generated by the moving parts such as counterweight iron 5 and a lifted heavy matter 6 is absorbed by the elastic potential energy generated by a spring set 2 when a pumping unit reverses; as the pumping unit runs in a reverse direction, the lifted heavy matter 6 is released from the braking of a brake mechanism 8, then the gravitational potential energy of the lifted heavy matter 6 enters the system; the application direction of the gravitational potential energy of the lifted heavy matter 6 is reverse to that of the gravitational potential energy of the counterweight iron 5, and the combined force of the gravity of the lifted heavy matter 6 and the elasticity of the spring set 2 is more than the force generated by the gravitational potential energy of the counterweight iron 5, so that the moving parts of the pumping unit move along the application direction of the elastic potential energy of the spring set 2, and the pumping unit starts to run in the reverse direction.

Summary of the invention is for the technical problem existed when commutating without beam pumping unit at present, present invention employs a kind of moving element kinetic energy of Active control and the mutual converting system (being called for short kinetic energy converting system) of spring force potential energy, it is characterized in that: kinetic energy converting system of the present invention is mainly adjusted retaining frame 3, guiding pairs 4, balance weight iron 5 by power plant 1, cluster spring 2, spring, formed by lifting heavy 6, base 7, braking mechanism 8 and controller 9, kinetic energy converting system of the present invention absorbs balance weight iron 5 when pumping unit commutates, by the kinetic energy of the moving elements such as lifting heavy 6 with the elastic force potential energy that compression or extension spring group 2 produce, because power plant 1 also take part in, compression spring set 2 is done work, so the elastic force potential energy stored by cluster spring 2 contains the kinetic energy of moving element and the energy of power plant 1 pair of cluster spring 2 acting, when the power supply and braking mechanism 8 that cut off power plant 1 enter brake operating mode, be braked by the gravitational potential energy of lifting heavy 6, the elastic force potential energy of cluster spring 2 just balances each other with the gravitational potential energy of balance weight iron 5, and system enters state of rest, when pumping unit enters inverted running operating mode, first allow braking mechanism 8 enter and unclamp operating mode, braking mechanism 8 is removed by the braking function of lifting heavy 6, by the gravitational potential energy interventional systems of lifting heavy 6, due to contrary with the force direction of balance weight iron 5 gravitational potential energy by the force direction of the gravitational potential energy of lifting heavy 6, the power that produces by the elastic force of the gravity of lifting heavy 6 and cluster spring 2 of the gravity potential the subject of knowledge and the object of knowledge making a concerted effort to be greater than balance weight iron 5 that produces, so the moving element of pumping unit moves along the force direction of the elastic force potential energy of cluster spring 2, pumping unit starts reverse direction operation, after pumping unit operation reaches pre-set velocity, power to again power plant 1, according to the force direction of gravitational potential energy, cluster spring 2, spring adjustment retaining frame 3, guiding pairs 4 all should at right angle setting, store the cluster spring 2 of elastic force potential energy, can make of normal spiral Compress Spring or extension spring, also can make of butterfly spring or autobody sheet, in the transfer process of energy, the energy due to power plant 1 pair of cluster spring 2 acting is only greater than the loss of switching energy slightly, and therefore, the conversion of energy needs the control of controlled device 9, transformation of energy follows the change over order of kinetic energy-elastic force potential energy-kinetic energy.
Below in conjunction with Figure of description and embodiment, the present invention will be further described.
Appended drawings 1 is the structural principle schematic diagram of kinetic energy converting system of the present invention, and wherein left figure is front view, and right figure is side view.Two large pulleys 10 are arranged on the top of pumping unit, are filled thereon by two main traction ropes 11, and are connected together by balance weight iron 5 with by the fluid column equivalent load 12 of lifting heavy 6 and oil well pump by two main traction ropes 11, form mechanical balance system.Power plant 1 and large pulley 10 link together with belt, are provided with braking mechanism 8 therebetween, do positive and negative rotation motion, drive and pumped by the fluid column equivalent load 12 of lifting heavy 6 and oil well pump under the control of controller 9.Be provided with cluster spring 2 in the lower end of balance weight iron 5, be used for absorbing the kinetic energy of moving element, spring adjustment retaining frame 3 and guiding pairs 4 are used for ensureing that cluster spring 2 is in optimum Working, and whole system is arranged on base 7.
Embodiment kinetic energy of the present invention converting system with current pumping unit compared with have three features: the first adopt the elastic force potential energy of cluster spring 2 to absorb and balanced oil extractor commutates time moving element kinetic energy; It two is produce second feature thus, is exactly that after power plant 1 commutate, driven object is a system in a basic balance, therefore, is light-load starting during starting; 3rd feature variable-speed operation that to be pumping unit variable-speed operation operating mode be not by power plant 1, but utilize and extend or reduce that commutation realizes stagnation period.Below in conjunction with embodiment, three features are further described.
The simple declaration of pumping unit load character: the load of the upper and lower stroke of pumping unit is very uneven, during upstroke, pumping unit needs the fluid column equivalent load 12 of mentioning by lifting heavy 6 (sucker rod) and oil well pump, and during down stroke, relied on deadweight just can fall by lifting heavy 6 (sucker rod), make the acting of power plant 1 extremely uneven like this.Do work evenly to make upper and lower stroke power plant 1, the balanced mode that have employed a kind of configuration of the present invention, if represent by the weight of lifting heavy 6 (sucker rod) with W2, the weight of the fluid column equivalent load 12 of oil well pump represents with W3, the weight of balance weight iron 5 represents with W1, and so the weight of balance weight iron 5 can be tried to achieve with following formula:
W1=W2+(1/2)W3
Above formula shows that the weight of balance weight iron 5 equals by the weight half sum of the fluid column equivalent load 12 of the weight of lifting heavy 6 (sucker rod) and oil well pump, under this configuration, during upstroke, owing to being balanced by the weight of lifting heavy 6 (sucker rod), also have the weight of the fluid column equivalent load 12 of half oil well pump to be configured on balance weight iron 5 in addition, just can so power plant 1 only need to promote acting to the weight of the oil well pump fluid column equivalent load 12 of half; During down stroke, because the weight of lifting heavy 6 (sucker rod) has been balanced, fluid column equivalent load 12 weight of oil well pump does not exist, and power plant 1 equally only need to promote acting to fluid column equivalent load 12 weight of the oil well pump being configured in half on balance weight iron 5 and just can.
Below kinetic energy converting system working procedure of the present invention is sketched.Assuming that the pumping unit in accompanying drawing is carrying out the running of upstroke, the balance weight iron 5 in figure is carrying out downward movement, and balance weight iron 5 contacts with following cluster spring 2, enters dynamic, potential energy converting and energy operating mode; The fluid column equivalent load 12 of balance weight iron 5 and lifting heavy 6 (sucker rod) and oil well pump continues descending under the driving of inertia energy, cluster spring 2 compression is downwards produced elastic force potential energy, if do not consider frictional loss, cluster spring 2 compression downwards produces elastic force potential energy should be equal with the kinetic energy entrained by pumping unit moving element, working principle of the present invention that Here it is.After pumping unit is completely out of service, kinetic energy converting system of the present invention does not start inverted running program at once, but by gathering the information of oil, casing annulus liquid level, judging the liquid supply rate of stratum to this well, finally determining that correct commutation stops, opens the time according to liquid supply rate again.Due to cluster spring 2 because of compression produce elastic force potential energy go out force direction commutate with pumping unit after startup optimization direction consistent, therefore, be light-load starting during the reverse starting of pumping unit.
