Description
Technical field
The utility model relates to pulling force sensor, relates in particular to the pulling force sensor that is used for petroleum machinery equipment oil pumper.
Background technology
Oil pumper is traditional pumping unit of oil field extensive use, is commonly called as " machine of kowtowing ", and Fig. 1 is the structural representation of pumping unit system.As shown in Figure 1, oil pumper 101 is an eccentric rod gear, usually directly drive by common asynchronous ac motor, oil pumper 101 is converted into moving up and down of oil pumper 101 heads with rotatablely moving of motor, by wire rope 102 pulling sucker rods 103, sucker rod 103 drives the fix up-and-down movement in cycle of oil well pump 104 again, oil pipe 105 elastic elongations move downward when descending, by formation pressure oil impregnate in oil well pump 104, oil pipe 105 elastic shrinkage move upward oil are promoted when up, make oil be pumped to ground under certain dynamic pressure.Long-pending wax or foreign material occur and stop up in oil pipe 105, will block sucker rod 103, the serious motor that also can cause wire rope 2 fractures or oil pumper 101 burns out.If on wire rope 102, connect a pulling force sensor 106, measure the pulling force of wire rope 101 in real time, just can in time pinpoint the problems, thereby emergency shutdown avoids occurring bigger fault.
Traditional pulling force sensor adopts resistance strain gage to form an electric bridge to carry out dynamometry, need the external world that power supply is provided, the pulling force signal will be outputed to receiving system simultaneously, so pulling force sensor and the external world need four connecting lines at least.Because the moving up and down of wire rope, connecting line also can movement therewith, the time one is long, is easy to cause the wearing and tearing of connecting line, can't normally move for a long time, and increase the workload of safeguarding greatly.
If adopt the mode of wireless data transmission, just need power by pulling force sensor self.Existing pulling force sensor generally adopts powered battery or solar powered.For the powered battery scheme, because the resistance of pulling force sensor is very little, so power consumption is bigger, and the electric weight of battery is limited, can not satisfy long use needs; For solar powered scheme, can not work at night, and solar panel damages easily.
The utility model content
Connecting line wearing and tearing at existing pulling force sensor, and the mode that adopts wireless data transmission can't fine solution powerup issue shortcoming, the applicant has carried out improving research, a kind of self electricity generation wireless pulling force sensor is provided, can utilize the characteristics self generating of motion, and transmit pulling force data by wireless mode.
The technical solution of the utility model is as follows:
A kind of self electricity generation wireless pulling force sensor, comprise power measuring circuit, single-chip microcomputer treatment circuit and wireless communication line that polyphone connects, comprise that also an inside is provided with the body of magnet steel and resonant springs, resonant springs is connected the body bottom, and magnet steel is arranged on the resonant springs; Described body outside is wound with coil, and rectification circuit is connected with coil and is connected with the capacitance energy storage mu balanced circuit, and the capacitance energy storage mu balanced circuit is connected with power measuring circuit, single-chip microcomputer treatment circuit and wireless communication line respectively, is its power supply.
Useful technique effect of the present utility model is:
The utility model utilizes pulling force sensor along with the characteristics that wire rope moves up and down, and the magnet steel in the body is vibrated under the effect of resonant springs, and coil cutting magnetic line produces electromotive force, obtains operating voltage after treatment, thereby realizes self power generation.Simultaneously, pulling force data is sent near data sink by Wireless transmission mode.The connecting line that efficiently solves existing pulling force sensor is easy to wear, and the powerup issue that adopts the wireless data transmission mode.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further.
As shown in Figure 2, the utility model comprises power measuring circuit 7, single-chip microcomputer treatment circuit 8 and the wireless communication line 9 that polyphone connects, comprise that also an inside is provided with the body 1 of magnet steel 3 and resonant springs 4, resonant springs 4 is connected body 1 bottom, and magnet steel 3 is arranged on the resonant springs 4; Body 1 outside is wound with coil 2, and rectification circuit 5 is connected with coil 2 and is connected with capacitance energy storage mu balanced circuit 6, and capacitance energy storage mu balanced circuit 6 is connected with power measuring circuit 7, single-chip microcomputer treatment circuit 8 and wireless communication line 9 respectively, is its power supply.
The course of work and principle:
When the utility model moved up and down along with wire rope, the magnet steel 3 in the body 1 also moved up and down thereupon, and the resonance function of resonant springs 4 makes magnet steel 3 fast vibration in body 1.Since body 1 outer winding around 2, coil 2 and magnet steel 3 both relative motions, coil 2 cutting magnetic lines, thus induced electromotive force in coil 2, produced.Because this relative motion is reciprocal, so generation is an alternating voltage.By rectification circuit 5, obtain DC voltage.Because the size of self power generation voltage is relevant with the frequency of wire circle and motion, so voltage can be very unstable.Behind capacitance energy storage mu balanced circuit 6, can obtain a galvanic current and press.This galvanic current is pressed and is provided for power measuring circuit 7, single-chip microcomputer treatment circuit 8 and wireless communication line 9.Power measuring circuit 7 is carried out signal amplification and A/D conversion with the pulling force data that records through single-chip microcomputer treatment circuit 8, near the data sink being sent to by wireless communication line 9 at last.
