[0019] Example 1

[0020] like Figure 1 , 2 As shown, a wellhead control system for realizing fully automatic oil tank filling includes an oil filling mechanism, a control mechanism and a storage mechanism; in a non-working state, the oil filling mechanism is placed in the storage mechanism;

[0021] The oil injection mechanism includes an oil injection pump 3, a hose 5 respectively arranged at the liquid inlet end and the liquid outlet end of the oil injection pump 3, and a throttle valve 4 arranged at the liquid inlet end of the oil injection pump 3; the throttle valve 4 prevents the oil from overflowing due to excessive injection; the hose 5 is an embedded steel wire hose;

[0022] In this embodiment, in order to facilitate fixing the oil injection pump during oil injection, the oil injection mechanism further includes a clamping block 8 disposed on the top of the oil injection pump. The structure of the clamping block 8 is a conventional clamp-type clamping member. The closed end surface in the free state is fixed to the clamping block 8 to ensure that the connection between the two does not affect the normal clamping operation of the clamping block.

[0023] The control mechanism includes an electronic liquid level meter 6 and a signal transmitter 7 electrically connected to each other, and a UPS 9 for supplying power to the oil injection pump 3 and the electronic liquid level meter 6. The signal transmitter 7 is electrically connected to the oil injection pump 3 and provides a signal to the oil injection pump according to the liquid level information of the electronic liquid level meter 6. The electronic liquid level meter 6 monitors the oil tank liquid level of the wellhead plate body 1.

[0024] In this embodiment, in order to facilitate the oil filling operation, the electronic liquid level meter 6, the signal transmitter 7 and the UPS 9 are fixed to the front end of the wellhead plate body 1;

[0025] The storage mechanism includes a placement box 2 arranged at the rear end of the wellhead plate body 1. The placement box 2 is a box body with a flexibly removable cover plate, and can be a drawer-type structure, a flip-type structure, or any other structural design that meets the storage and retrieval operations of the control mechanism.

[0026] The utility model has the following advantages:

[0027] (1) Easy to store: The oil injection pump 3 and the throttle valve 4 are placed in the pull-out placement box 2, and the embedded steel hose 5 is coiled and placed in the pull-out placement box 2. The pull-out placement box 2 is placed behind the wellhead plate and can be pulled out at any time when in use. There is no need to find tools on site when injecting oil;

[0028] (2) Convenient for on-site fixing: The front and rear ends of the oil injection pump 3 are provided with an embedded steel wire hose 5, which can be bent into various shapes and then fixed, so as to be convenient for on-site insertion into an oil drum or a wellhead oil tank. During operation, there is no need to press the hose in real time, and there is no risk of the hose floating or the hose not contacting the oil. At the same time, the oil injection pump 3 and the clamping block 8 are fixed, and when in use, the hose can be clamped at any position of the wellhead or on-site by the clamping block 8. The installation is convenient and quick, and no manual lifting by operators is required;

[0029] (3) Automatically monitor the oil level after starting and automatically stop after operation: the electronic liquid level meter 6 is connected to the signal transmitter 7, and the signal transmitter 7 is connected to the oil filling pump 3 to provide a signal for the oil filling pump; the electronic liquid level meter 6, the oil filling pump 3 and the UPS 9 are connected and powered by the UPS; after the pull-out placement box 2 is pulled out and the embedded steel wire hose 5 is inserted, the oil filling pump 3 is started and the automatic oil filling begins. When the reading of the electronic liquid level meter 6 reaches the preset parameter, the electronic liquid level meter 6 automatically controls the oil filling pump 3 to stop through the signal transmitter 7. No human operation is required throughout the process, which realizes intelligence and convenience;

[0030] (4) Convenient operation: On-site personnel do not need to look for oil injection tools, press the hose during the oil injection process, lift the oil injection pump manually, or observe the oil level in real time. They only need to pull out the oil injection pump, plug in the hose, and start the oil injection pump to complete the oil injection operation.
