Description

Technical Field

[0001] The invention relates to the technical field of beam pumping units, and in particular to a reversing pumping unit with a proximity warning structure. Background Art

[0002] A beam pump is a pump that contains a beam pump, which is reversed by a connecting rod mechanism and balanced by a crank weight. It is one of the main types of pumps currently used in oil fields. When a beam pump is actually used, a responsible person usually manages the beam pumps in an area, and he or she will not always stay near a group of beam pumps.

[0041] The specific usage and function of this embodiment are as follows:

[0042] In order to avoid danger caused by non-staff members approaching the beam pumping unit 1, induction monitoring can be implemented to detect whether there is any member approaching the beam pumping unit 1. In actual application, a certain number of monitoring blocks 3 are selected according to the induction monitoring requirements and installed around the outer end surface of the base of the beam pumping unit 1;

[0043] Through the sliding cooperation between the sliding ball 3029 and the slideway 101, the position of the monitoring block 3 is adjusted along the slideway 101. When the position adjustment is completed, the matching plug block 4 can be inserted into the slot b308 in a limited manner, and the locking stud 3013 can be screwed along the threaded through hole 3020, so that the locking stud 3013 is closely attached to the outer end surface of the base of the walking beam pumping unit 1, thereby realizing the limited fixing of the position of the monitoring block 3;

[0044] In daily use, the outer peripheral surface of the annular pressing block 3016 is in contact with the monitoring on-off switch 3022. At this time, the monitoring on-off switch 3022 is in a pressed start state, and the monitoring on-off switch 3022 feedbacks a signal to the microcontroller 3028, and the microcontroller 3028 controls the human infrared sensor 302 to start sensing;

[0045] When a person approaches the beam pumping unit 1, the human infrared sensor 302 senses the human infrared signal, and the human infrared sensor 302 gives a feedback signal to the microcontroller 3028. The microcontroller 3028 immediately starts the buzzer 3027 to realize a high-decibel buzzer warning to warn the current person not to approach further. At the same time, the microcontroller 3028 also sends a message to the mobile device 3026 of the person in charge of the beam pumping unit 1 through the 5G module 3025 to remind that someone is approaching the beam pumping unit 1 and needs to go there in time.

[0046] When the person approaching is the person in charge of the beam pumping unit 1, he can insert the matching plug block 4 into the slot c3010, and rotate the twisting column b309 to drive the annular pressing block 3016 to rotate, and rotate the arrow end of the arrow pointing mark c3011 to a state corresponding to the position of the arrow end of the arrow pointing mark d3012. At this time, the cutting groove 3017 corresponds to the position of the monitoring start-stop switch 3022, and the monitoring start-stop switch 3022 will be in a non-pressed start state, thereby realizing the monitoring shutdown, so that the person in charge of the beam pumping unit 1 can perform corresponding operations;

[0047] The slot b308 and the slot c3010 are designed to have an elliptical groove structure, so that without the matching insertion of the plug block 4, it is impossible to insert the common tools into the slot b308 and the slot c3010 to realize the rotation operation of the locking stud 3013 and the annular pressure block 3016, thereby effectively preventing the person in charge of the non-walking beam pumping unit 1 from turning off the induction monitoring and affecting the limit fixation of the position of the monitoring block 3.

[0048] Embodiment 2: Based on the first embodiment, a reversing pumping unit with a proximity warning structure is provided. The reversing pumping unit with a proximity warning structure further includes: when it is necessary to add or remove the monitoring block 3, it is necessary to first remove the matching insert 2 to facilitate the disassembly and assembly operation of the monitoring block 3. The specific operation is as follows:

[0049] Insert the matching plug block 4 into the slot a204 with the matching limit, and rotate the torsion column a203 to synchronously drive the limiting block 206 to rotate, and rotate the arrow end of the arrow pointing to the mark b205 to a state corresponding to the arrow end of the arrow pointing to the mark a102. At this time, the matching cut surface a207 of the limiting block 206 faces the open end of the rotating storage chamber 208, and the limiting block 206 as a whole will be completely rotated and stored inside the rotating storage chamber 208, so the limiting of the limiting block 206 and the limiting slot 105 is released. At this time, without the limiting of the limiting block 206 and the limiting slot 105, the matching insert block 2 can be slid upward along the limiting slot 104 to remove it to expose the missing slot 103. At this time, the monitoring block 3 can be disassembled and assembled according to needs;

[0050] Furthermore, by designing the slot a204 to be an elliptical groove structure, it is impossible to insert the matching insert 4 into the slot a204 using common tools to release the limit of the matching insert 2 without the matching insert 4, thereby effectively preventing the person in charge of the non-walking beam pumping unit 1 from disassembling the matching insert 2.

[0051] The above description is merely an exemplary embodiment of the present invention and is not intended to limit the protection scope of the present invention. The protection scope of the present invention is determined by the appended claims.
