Description

Technical Field

[0001] This utility model relates to the field of deoxidation technology, and more specifically, to a device for deoxidizing the outer skin of an oil perforation projectile casing. Background Technology

[0002] Perforating projectiles are pyrotechnic devices used to penetrate casings, cement sheaths, and strata during the perforation process. Shaped charge perforating projectiles are the most widely used and also the most efficient. A typical shaped charge perforating projectile consists of a casing, detonating charge, main explosive, and shaped charge liner. The casing is usually made of steel, with the primary requirement being pressure resistance to ensure the formation of an ideal jet shape. The main explosive is the energy source for forming the shaped jet and is a high-energy solid explosive. The purpose of the perforating projectile casing is to generate the jet beam after the main explosive detonates, forming the perforation channel. The casing is generally conical. During long-term storage, its surface is prone to oxidation. Before use, the oxide layer on the casing needs to be removed. However, the shape of the casing makes fixing it during deoxidation inconvenient, thus affecting the ease of installation and fixation during the deoxidation process. Utility Model Content

A support spring is provided on the outer side of the upper end of the adjusting clamping rod. A limiting slip ring is provided at the upper end of the support spring. A limiting mounting groove is provided on the inner side of the lower end of the limiting slip ring.

[0008] In a preferred embodiment, the number of support legs is multiple, and they are arranged in an array on both sides of the vertical central axis in the top view of the processing box.

[0009] The adjustment groove is set in an arc shape in the main viewing direction. The adjustment motor is electrically connected to an external control device. The output shaft of the adjustment motor is connected to the oxidation support frame.

[0010] In a preferred embodiment, the number of fixed connecting rods is multiple, and they are arranged in a ring array outside the center point of the mounting support plate in the top view direction;

[0011] The rotary motor is electrically connected to the external control equipment, and there are multiple supporting rods arranged in a ring array outside the center point of the rotary support block in the top view direction.

The output shaft of the adjustment motor 6 is connected to the oxidation support frame 4. There are multiple fixed connecting rods 8, which are arranged in a ring array outside the center point of the mounting support plate 9 in the top view direction.

[0026] like Figure 4As shown, the output shaft of the rotary motor 10 is provided with a rotary support block 11 at the upper end of the mounting support plate 9. The upper end of the rotary support block 11 is provided with a support connecting rod 12. The upper end of the support connecting rod 12 is provided with a cross fixing block 13. An adjusting clamping rod 14 is provided on the outer side of one end of the cross fixing block 13. The lower end of the adjusting clamping rod 14 is provided with a counterweight block 15. The counterweight block 15 will drive the adjusting clamping rod 14 to rotate around the rotary connector 19, thereby facilitating the upper end of the adjusting clamping rod 14 to be locked on the inner end face of the oil perforation shell.

[0027] The cross-shaped fixing block 13 and the adjusting clamping rod 14 are connected by a rotating connector 19. The outer side of the upper end of the adjusting clamping rod 14 is provided with a support spring 16. The upper end of the support spring 16 is provided with a limiting slip ring 17. The inner side of the lower end of the limiting slip ring 17 is provided with a limiting mounting groove 18.

[0030] Working principle of this utility model:

[0031] When using this invention, the operator, based on the shape of the outer end face of the oil perforation projectile casing, drives the adjusting motor 6 through an external control device. This motor rotates the deoxidation support frame 4 at an angle. Then, the operator places the oil perforation projectile casing onto the outer end face of the adjusting clamping rod 14. Due to the significant weight of the oil perforation projectile casing, it presses against the upper end of the limiting slip ring 17. Subsequently, the counterweight 15 causes the adjusting clamping rod 14 to shift to one side, thereby fixing the oil perforation projectile casing. Then, the deoxidation component 5 and the rotary motor 10 can be driven to work through the external control device. The rotary motor 10 rotates the oil perforation projectile casing, and the deoxidation component 5 performs deoxidation work on the surface of the oil perforation projectile casing.
