A cleaning device for an oil testing string

Abstract

This utility model proposes a cleaning device for an oil testing string, relating to the field of cleaning the inner wall of an oil testing string. It includes a housing with an installation box on the left side. In this cleaning device, rotating the handle drives a connecting rod to rotate. The rotation of the connecting rod causes two sliding plates to move closer together. The sliding plates can move the insert block out of the insertion hole on the insert plate, releasing the limiting effect on the insert plate. At this point, pulling the installation block to one side completes the disassembly of the cleaning assembly. Rotating the handle causes the sliding plates to compress a spring, generating elastic force. Then, the insert plate is inserted into the installation box through the slot, and the handle is released. The sliding plates, under the elastic force of the spring, drive the insert block into the insertion hole on the insert plate, completing the installation of the cleaning assembly, thus improving its disassembly and assembly efficiency. Rotating the fixing plate drives the threaded rod to rotate, causing the threaded rod to move within the threaded groove on the installation block, thereby completing the disassembly and assembly of the cleaning head.

Description

Technical Field

[0001] This utility model relates to a cleaning device, specifically a cleaning device for an oil testing tubing, belonging to the technical field of cleaning the inner wall of an oil testing tubing. Background Technology

[0002] The so-called oil testing is a process that uses a set of specialized equipment and methods to reduce the pressure of the fluid column in the well to allow the fluid in the producing layer to flow into the well and be induced to the surface, thereby obtaining data such as fluid production, pressure, temperature, fluid properties, flow patterns and formation parameters.

[0003] A wellbore testing tubing inner wall cleaning device disclosed in Chinese Patent Application Publication CN219985632U features a snap-fit ​​cleaning mechanism. After cleaning the inner wall of the testing tubing, the device is rotated to disengage the bottom of the threaded cap from the top of the slot block. Rotating the threaded head allows the cleaning head to be removed for cleaning. Moving the lever disengages the locking tongue from the insert, partially separating the cleaning arm connecting assembly and removing the cleaning head assembly, thus enabling the cleaning process of the snap-fit ​​cleaning mechanism. When needed, the disassembled parts are inserted, and installation is quick and easy by moving the lever and rotating the threaded cap, improving the efficiency of the cleaning device's installation and disassembly.

[0004] The solutions in the above patents allow for the removal and cleaning of the cleaning head, as well as the removal of the cleaning head connecting component, which enables the cleaning process of the snap-fit ​​cleaning mechanism. However, this disassembly process requires a large number of components, and the assembly and disassembly are quite cumbersome, significantly extending the operation time, reducing work efficiency, and easily affecting the cost.

[0005] Therefore, a cleaning device for the oil testing tubing is proposed here. Utility Model Content

[0008] The assembly / disassembly assembly includes a rotating rod rotatably connected to the inner wall of the mounting box, with one end of the rotating rod extending to the outside of the mounting box. A connecting rod is fixed to the outer surface of the rotating rod, and sliding plates are hinged to both the upper and lower ends of the connecting rod. The outer surface of the sliding plates slides in contact with the inner wall of the mounting box. Multiple springs are fixed to the side of the two sliding plates that are close to each other, and insert blocks are fixed to the side of the two sliding plates that are far apart from each other.

[0009] Furthermore, the inner wall of the mounting box is provided with a sliding groove, and a slider is slidably connected to the inner wall of the sliding groove. One side of the slider is fixed to one side of the sliding plate, and a handle is fixed to one end of the rotating rod that passes through the mounting box.

[0010] Furthermore, the cleaning component includes a mounting block, a plug plate is fixed to one side of the mounting block, the plug plate has a plug hole, and the plug block is inserted into the plug hole.

[0011] Furthermore, a slot is provided on one side of the mounting box, and the insert plate is inserted into the slot.

[0012] Furthermore, a first electric push rod is fixed on both the upper and lower sides of the mounting block.

[0015] This utility model provides a cleaning device for an oil testing string, which has the following beneficial effects:

[0016] The cleaning device for this oil testing string works by rotating a handle to drive a rotating rod, which in turn drives a connecting rod. The rotation of the connecting rod causes two sliding plates to move closer together. The sliding plates then move the insert block out of the insertion hole on the insert plate, releasing the limiting position on the insert plate. At this point, pulling the mounting block to one side completes the disassembly of the cleaning component. When it is necessary to install the cleaning component, rotating the handle causes the sliding plate to compress the spring, generating elastic force. Then, the insert plate is inserted into the mounting box through the slot, and the handle is released. At this point, the sliding plate, under the elastic force of the spring, drives the insert block to insert into the insertion hole on the insert plate, completing the installation of the cleaning component, thereby improving its disassembly and assembly efficiency.

[0017] The cleaning device for the oil testing string rotates the threaded rod by rotating the fixed plate, causing the threaded rod to move within the threaded groove on the mounting block, thereby completing the disassembly and assembly of the cleaning head and improving its disassembly and assembly efficiency.

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0029] Please see Figures 1-4 The present invention proposes the following implementation scheme: a cleaning device for an oil testing column, including a housing 1, an installation box 4 is provided on the left side of the housing 1, a cleaning component 3 is provided on the left side of the installation box 4, and a disassembly component 2 is provided on the installation box 4.

[0030] The inner wall of the outer casing 1 is provided with a through groove 102. A rotary motor 7 is fixed to the inner wall of the through groove 102. A fixing rod 8 is fixed to the output end of the rotary motor 7. One end of the fixing rod 8 passes through the outer casing 1 and is fixed to one side of the mounting box 4. By starting the rotary motor 7, the fixing rod 8 can be driven to rotate. The fixing rod 8 can drive the cleaning component 3 to rotate through the mounting box 4, thereby cleaning the inner wall of the oil test column.

[0031] The upper and lower sides of the outer casing 1 are fixed with a second electric push rod 5. The end of the second electric push rod 5 away from the outer casing 1 is equipped with a caster wheel 6. By activating the second electric push rod 5, the caster wheel 6 can be moved to adapt to the diameter of the inner wall of the oil test tube. The outer side of the outer casing 1 is fixed with a handle 101.

[0032] Please refer to this carefully. Figure 1 and Figure 3 The cleaning component 3 includes a mounting block 301, and a plug plate 307 is fixed on one side of the mounting block 301. The plug plate 307 has a plug hole 3071.

[0033] First electric push rods 302 are fixed on both the upper and lower sides of the mounting block 301. A fixing block 303 is fixed to the end of the first electric push rod 302 away from the mounting block 301. A threaded rod 306 is threadedly connected to the inner wall of the fixing block 303 away from the first electric push rod 302. A fixing plate 304 is fixed to the end of the threaded rod 306 away from the fixing block 303. A cleaning head 305 is fixed to the end of the fixing plate 304 away from the fixing block 303. By activating the first electric push rod 302, the cleaning head 305 can be moved to adapt to the diameter of the inner wall of the oil test tube column.

[0034] By rotating the fixed plate 304, the threaded rod 306 is driven to rotate, causing the threaded rod 306 to move in the threaded groove on the fixed block 303, thereby completing the disassembly and assembly of the cleaning head 305 and improving its disassembly and assembly efficiency.

[0035] Please refer to this carefully. Figure 1 and Figure 4 The assembly / disassembly component 2 includes a rotating rod 201 rotatably connected to the inner wall of the mounting box 4, with one end of the rotating rod 201 extending to the outside of the mounting box 4. A connecting rod 202 is fixed to the outer surface of the rotating rod 201. Slide plates 203 are hinged to both the upper and lower ends of the connecting rod 202. The outer surface of the slide plates 203 slides in contact with the inner wall of the mounting box 4. Multiple springs 204 are fixed to the side of the two slide plates 203 that are close to each other. Insert blocks 205 are fixed to the side of the two slide plates 203 that are far apart from each other. The insert blocks 205 are inserted into the insertion holes 3071.

[0036] The inner side wall of the mounting box 4 is provided with a sliding groove 206, and a slider 207 is slidably connected to the inner wall of the sliding groove 206. One side of the slider 207 is fixed to one side of the slide plate 203. A handle 208 is fixed to one end of the rotating rod 201 that passes through the mounting box 4.

[0037] The mounting box 4 has a slot 401 on one side, and the insert plate 307 is inserted into the slot 401.

[0038] By rotating the handle 208, the rotating rod 201 is driven to rotate, which in turn drives the connecting rod 202 to rotate. The rotation of the connecting rod 202 causes the two sliding plates 203 to move closer to each other. The sliding plates 203 can then drive the insert block 205 to move out of the insertion hole 3071 on the insert plate 307, releasing the restriction on the insert plate 307. At this time, pulling the mounting block 301 to one side completes the disassembly of the cleaning component 3. When it is necessary to install the cleaning component 3, rotating the handle 208 causes the sliding plate 203 to compress the spring 204, causing it to generate elasticity. Then, the insert plate 307 is inserted into the mounting box 4 through the slot 401, and the handle 208 is released. At this time, the sliding plate 203 will drive the insert block 205 to insert into the insertion hole 3071 on the insert plate 307 under the elasticity of the spring 204, completing the installation of the cleaning component 3, thereby improving its disassembly and assembly efficiency.

[0039] In use, when the cleaning component 3 needs to be disassembled from the outer casing 1, the handle 208 is rotated. Rotating the handle 208 causes the rotating rod 201 to rotate, which in turn causes the connecting rod 202 to rotate. The rotation of the connecting rod 202 causes the two sliding plates 203 to move closer to each other. The sliding plates 203 cause the insert block 205 to move out of the insertion hole 3071 on the insert plate 307, releasing the restriction on the insert plate 307. At this time, pulling the mounting block 301 to one side completes the disassembly of the cleaning component 3. Then, rotating the fixing plate 304 drives the threaded rod 306. Rotating the screw rod 306 causes it to move within the threaded groove on the fixed block 303, thereby completing the disassembly and assembly of the cleaning head 305 and improving its disassembly and assembly efficiency. When the cleaning component 3 needs to be installed, rotating the handle 208 causes the sliding plate 203 to compress the spring 204, generating elasticity. Then, the insert plate 307 is inserted into the mounting box 4 through the slot 401, and the handle 208 is released. At this time, the sliding plate 203 will drive the insert block 205 to be inserted into the insertion hole 3071 on the insert plate 307 under the elasticity of the spring 204, completing the installation of the cleaning component 3 and thus improving its disassembly and assembly efficiency.
