Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
as shown in figures 1 to 3, the automatic cleaning and environment-friendly device for the sucker rod in operation comprises a device body 1, a section of conical surface is arranged outside the middle section of the device body 1, an included angle between the conical surface and the central axis of the device body 1 is 45 degrees, an outer shell 6 is fixed outside the conical surface, the outer shell 6 is welded on the device body 1, a hollow injection cavity 7 is formed between the outer shell 6 and the device body 1, a quick connection joint 2 is connected onto the outer shell 6, and the quick connection joint 2 is communicated with the injection cavity 7. The quick connection joint 2 comprises a quick connection joint body 2-1, the left end of the quick connection joint body 2-1 is connected to the outer shell 6, the right end of the quick connection joint body is connected with a sealing ball head 2-2, a connection nut 2-3 is arranged outside the sealing ball head 2-2, and the connection nut 2-3 is quickly connected with a well site water source joint to form a water inlet channel, provide a cleaning water source and facilitate disassembly, installation and replacement.
The device body 1 is connected with a plurality of spray cleaning heads 3, and the included angle between the axes of the spray cleaning heads 3 and the axis of the device body 1 is 45 degrees and is vertical to the conical surface of the device body 1. The spray washing head 3 comprises a hollow spray washing head body 3-2, a water inlet is formed in the side wall of the middle of the spray washing head body 3-2 and is located in the spray cavity 7, one end of the spray washing head body 3-2 is connected with a spray washing head gland 3-3, a spray washing head nozzle 3-1 is fixed on a water outlet at the other end of the spray washing head body, and the outlet of the spray washing head nozzle 3-1 is aligned with a sucker rod in the center of the spray washing head body 1. The number of the spray cleaning heads 3 can be 6, and the spray cleaning heads are uniformly distributed along the circumferential direction, so that the 6 spray nozzles are aligned to the sucker rod together. The device body 1 upper portion inboard threaded connection has gland 5, put sealed paraffin removal ring 4 between gland 5 and the device body 1, sealed paraffin removal ring 4 all is equipped with the inclined plane of certain angle from top to bottom, can realize reliable sealing through extrusion deformation with the upper portion inclined plane of device body 1 and the lower part inclined plane of sealing ring gland 5, simultaneously, the sucker rod is worn out from its centre hole, make sealed paraffin removal ring 4 closely laminate with the sucker rod pole footpath through screwing up sealing ring gland 5, both guarantee the reliable sealing of the body of rod, can strike off remaining greasy dirt on the body of rod again totally.
