Description

Technical Field

[0001] This utility model relates to the field of pulse generator device technology, and in particular to a petroleum directional pulse generator. Background Technology

[0002] A pulse generator is a device that generates electrical pulse signals. In oilfield operations, pulse generators help workers perform formation testing, physical property measurement, and well monitoring by generating high-voltage, high-speed electrical pulse signals. Its working principle mainly utilizes the charging and discharging process of a capacitor to generate instantaneous high-voltage pulses, thereby enabling the testing and measurement of the formation.

[0003] The existing patent, with publication number "CN204941530U," describes a drilling pulse generator for preventing key debonding. The generator includes a mud pulse generator and a circulation sleeve. The mud pulse generator is equipped with an open spring plate, and the circulation sleeve contains a positioning key. The mud pulse generator is inserted into the circulation sleeve from the top, and the positioning key holds the spring plate below it. The spring plate is made of an elastic metal material. The opening width of the spring plate is smaller than the width of the positioning key. When the mud pulse generator is subjected to mud slurry and tends to debond, the force of the spring plate and the positioning key fixes the instrument within the circulation sleeve, thereby significantly reducing the likelihood of key debonding and improving the instrument's stability.

[0004] The inventors believe that there are still some shortcomings. The positioning key locks the spring plate at the bottom, making it inconvenient to operate when disassembling the pulse generator. To address the above problems, a petroleum directional pulse generator is needed. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a petroleum directional pulse generator.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A petroleum directional pulse generator includes a protective sleeve, inside which a pulse generator body is installed. A pair of slots are formed on the surface of the pulse generator body, and a limiting plate is inserted into the inner wall of each of the slots. The limiting plate is adapted to the inner wall of the slot. A removable positioning mechanism is formed on the surface of the protective sleeve.

[0008] The easy-to-disassemble positioning mechanism includes a pair of clearance holes on the surface of the protective cover. The inner walls of the pair of clearance holes are slidably connected to L-shaped plates. A top plate is fixedly connected to the surface of the limiting plate. An inclined surface is provided on the surface of the L-shaped plate. The lower surface of the top plate is slidably connected to the surface of the inclined surface.

[0009] Preferably, a push plate is fixedly connected to the surface of the L-shaped plate, and the surface of the push plate is provided with an arc-shaped groove.

[0010] Preferably, a first spring is fixedly connected to the inner wall of the clearance hole, and the surface of the first spring is in contact with the inner wall of the arc-shaped groove.

[0011] Preferably, the inner wall of the protective sleeve is provided with a pair of mounting grooves, the mounting grooves are connected to the clearance hole, the inner wall of the clearance hole is fixedly connected with a sealing plate, and the lower surface of the sealing plate is slidably connected to the surface of the L-shaped plate.

[0012] Preferably, a second spring is fixedly connected to the inner wall of the mounting groove, and one end of the second spring is fixedly connected to the surface of the limiting plate.

[0013] Preferably, the inner wall of the protective sleeve is provided with a sloping baffle, the surface of the sloping baffle is in contact with the surface of the pulse generator body, and a sealing ring is installed on the surface of the pulse generator body.

[0014] The beneficial effects of this utility model are as follows:

[0015] The push plate stretches the two ends of the first spring through the arc-shaped groove. The advantage of using the arc-shaped groove is that it can effectively prevent the first spring from detaching from the groove. At the same time, the push plate is subjected to the pulling force from the two ends of the first spring. The L-shaped plate drives the top plate to move away from the pulse generator body through the inclined surface. The movement of the top plate causes the limiting plate to move and separate from the slot. At this time, the pulse generator body is pulled out from the protective sleeve, achieving a quick release effect. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-6 A petroleum directional pulse generator includes a protective sleeve 1, a pulse generator body 2 installed inside the protective sleeve 1, a pair of slots 3 opened on the surface of the pulse generator body 2, and a limiting plate 4 inserted into the inner wall of each pair of slots 3. The limiting plate 4 is adapted to the inner wall of the slot 3, and a removable positioning mechanism is opened on the surface of the protective sleeve 1.

[0025] The easy-to-disassemble positioning mechanism includes a pair of clearance holes 8 on the surface of the protective sleeve 1. The inner walls of the pair of clearance holes 8 are slidably connected to L-shaped plates 12. The surface of the limiting plate 4 is fixedly connected to a top plate 6. The surface of the L-shaped plate 12 is provided with an inclined surface 13. The lower surface of the top plate 6 is slidably connected to the surface of the inclined surface 13.

[0026] By setting a pair of slots 3, positioning space is provided for the insertion of the limiting plate 4. By setting a protective sleeve 1, the pulse generator body 2 is protected. By setting a clearance hole 8, the sliding space of the L-shaped plate 12 is cleared. By setting an inclined surface 13, the height of the top plate 6 and the limiting plate 4 is adjusted by changing the position of the inclined surface 13. When the limiting plate 4 is separated from the slot 3, the limiting of the pulse generator body 2 installed in the protective sleeve 1 is released, and disassembly is realized.

[0027] In this utility model, a push plate 9 is fixedly connected to the surface of the L-shaped plate 12, and an arc-shaped groove 10 is formed on the surface of the push plate 9.

[0028] By setting the arc-shaped groove 10, the force on the first spring 11 is kept stable. The advantage of using the arc-shaped groove 10 is that it can effectively prevent the first spring 11 from falling out of the groove 10, while making the push plate 9 subject to the pulling force from both ends of the first spring 11.

[0029] In this utility model, a first spring 11 is fixedly connected to the inner wall of the clearance hole 8, and the surface of the first spring 11 is in close contact with the inner wall of the arc-shaped groove 10.

[0030] By setting the first spring 11, the push plate 9 and the L-shaped plate 12 are driven to reset as a whole.

[0031] In this utility model, the inner wall of the protective sleeve 1 is provided with a pair of mounting grooves 16, which are connected to the clearance hole 8. The inner wall of the clearance hole 8 is fixedly connected with a sealing plate 7, and the lower surface of the sealing plate 7 is slidably connected to the surface of the L-shaped plate 12.

[0032] By setting the sealing plate 7, a seal is formed so that the open space formed by the mounting groove 16 and the clearance hole 8 is just adapted to the surface of the sliding L-shaped plate 12, preventing external contaminants from entering the protective sleeve 1.

[0033] In this utility model, a second spring 5 is fixedly connected to the inner wall of the mounting groove 16, and one end of the second spring 5 is fixedly connected to the surface of the limiting plate 4.

[0034] By setting a second spring 5, the locking of the limiting plate 4 is kept stable.

[0035] In this utility model, the inner wall of the protective sleeve 1 is provided with a sloping baffle 15, the surface of the sloping baffle 15 is in contact with the surface of the pulse generator body 2, and a sealing ring 14 is installed on the surface of the pulse generator body 2.

[0036] By setting the inclined baffle 15 to fit against the surface of the pulse generator body 2, the installation of the pulse generator body 2 is kept stable, and the sealing ring 14 is set to perform sealing and waterproofing operations.

[0037] Working principle: The protective sleeve 1 protects the pulse generator body 2. When it is necessary to remove the pulse generator body 2 from the protective sleeve 1, the push plate 9 is pushed. The push plate 9 drives the two ends of the first spring 11 to stretch and lengthen through the arc groove 10. At this time, the L-shaped plate 12 slides with the push plate 9. The L-shaped plate 12 drives the top plate 6 to move away from the pulse generator body 2 through the inclined surface 13. During the movement of the limiting plate 4, the second spring 5 is compressed and shortened. The top plate 6 drives the limiting plate 4 to move and separate from the slot 3, releasing the locking restriction between the limiting plate 4 and the slot 3. The pulse generator body 2 can be pulled out from the protective sleeve 1, achieving the effect of quick disassembly. When the pulse generator body 2 is installed in the protective sleeve 1, since the limiting plates 4 are installed and inserted in both slots 3, the overall position of the pulse generator body 2 is positioned. At the same time, one side surface of the pulse generator body 2 is in contact with the surface of the inclined baffle 15 inside the protective sleeve 1, maintaining the practical stability of the pulse generator body 2. Through the above structure, the quick disassembly effect is achieved.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
