[0002] The oil and gas mixed fluid produced by single well station associated natural gas oil production needs to be separated through a separation tank, and after the liquid oil and natural gas are separated, the flow of oil or natural gas is measured through a metering device. In order to save the investment cost of ground gathering and transportation in the oilfield production process, a large number of oil wells now adopt a ring gathering and transportation mode for gathering and transporting the produced medium of the oil production well. This gathering and transportation mode cannot measure the produced liquid volume and gas production of each oil production well at the wellhead, and therefore, an oil wellhead metering device is needed.

[0003] Although the small pry-mounted oil wellhead metering device disclosed in the authorized announcement No. CN215108883U is convenient to move the whole device through walking wheels, is convenient to relieve the jolt and vibration force in the moving process, and reduces the damage risk of the whole device caused by the large resonance force generated by the large jolt and vibration force, the device does not have protection for the oil metering device when in use.

[0030] Please refer to the attached Figure 1 -Appendix Figure 5 In a preferred implementation, the baffle 5 close to the base 1 is provided with an inclined slot 19, and the inclined slot 19 is inclinedly arranged, and a convex column 20 is slidingly installed inside the inclined slot 19. Both ends of one side of the base 1 are provided with a first notch 6, and both the two first notches 6 penetrate the one side of the base 1. Both convex columns 20 pass through the two first notches 6 and are fixedly installed at the ends of the two sliding plates 16. Four corners of the four parts of the base 1 are provided with rollers 13, and one side of the base 1 is provided with a driving motor 9. The output shaft of the driving motor 9 penetrates one side of the base 1 and is installed at the center of one end of the lead screw 17. The two sliding plates 16 are moved, and the baffle 5 is moved up and down synchronously when the sliding plate 16 is moved through the convex column 20 and the inclined slot 19, which further facilitates the limiting of the protective door 4.

[0031] From the above description, it can be seen that the above-mentioned embodiments of the present application achieve the following technical effects: First, in use, the oil in the oil outlet pipe 14 can be continuously measured by the ultrasonic flowmeter 15. When the device needs to be moved, it is necessary to determine whether the protective door 4 is closed. If the protective door 4 is not closed, the driving motor 9 is started to drive the screw rod 17 to rotate, which drives the two sliding plates 16 to move, which drives the four movable rods 18 and the two protruding columns 20 to move, which drives the two inclined grooves 19 to move, which drives the two baffle plates 5 and the two extension blocks 23 to move upwards. Since the protective door 4 is not closed, the extension block 23 cannot move upwards due to contact with the protective door 4, ensuring that the base 1 is in a closed state when moving (equivalent to self-checking whether the protective door 4 is closed), preventing the protective door 4 from being forgotten to close when moving. If the protective door 4 is in a closed state, the baffle plate 5 and the extension block 23 will move upwards, so that the baffle plate 5 can block the closed protective door 4, avoiding the situation that the protective door 4 is automatically opened when moving the device, reducing the protection effect. The synchronous movement of the four movable rods 18 drives the friction plate 12 to move upwards, i.e. the contact between the friction plate 12 and the ground is released. At this time, the device can be easily moved by the roller 13. When the device does not need to be moved, the driving motor 9 is reversed to make the friction plate 12 contact the ground and make the baffle plate 5 and the extension block 23 move downwards, not blocking the opening of the protective door 4. When the protective door 4 needs to be opened, the protective door 4 first contacts the inclined block 24 and moves the inclined block 24 downwards. At this time, the spring rod 25 generates an elastic force until the protective door 4 passes over the inclined block 24. At this time, the elastic force generated by the spring rod 25 drives the inclined block 24 to move upwards, thereby limiting the protective door 4, avoiding the situation that the protective door 4 shakes and collides with the body of the worker or collides with other parts when opening the protective door 4 for maintenance, thereby improving the use effect of the device.

[0032] In addition, it should be understood that although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the description of the specification is only for the sake of clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that those skilled in the art can understand.
