Description

Technical Field

[0001] This utility model relates to the field of packer technology, specifically a novel combined packer. Background Technology

[0002] A packer is a device or tool used to isolate, divide, or enclose an object or space; they are typically designed to have a sealing property to prevent or restrict the flow of substances or cross-contamination; in industrial production processes, packers may be used to isolate different production areas or workstations to prevent contamination, cross-contamination, or leakage of hazardous substances; packers can help control environmental conditions and ensure the safety and reliability of production processes.

[0003] A combined packer (application number: 202421105012.6) uses an arc-shaped plate to drive a spring to contract and rebound, causing a friction block to adhere to the well wall, thus facilitating packer fixation and solving the problem that most packers are inconvenient to fix to the well wall, improving the practicality of the packer. However, the above-mentioned issues still exist. When using the packer, both ends are open. When transporting or moving the packer, impurities can easily enter through the ends of the packer, making it difficult to shield and protect the ends. This can easily lead to impurities entering the packer and affecting normal use. Furthermore, when installing the packer, one end is connected by a thread, making it difficult to apply lubricant to the threaded part, which can easily cause sticking during use. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of existing technologies, such as the inconvenience of shielding and protecting the end of the packer, which makes it easy for impurities to enter the packer and affect normal use, and the inconvenience of applying lubricating oil to the threaded part, which makes it easy to cause sticking during use. Therefore, a new type of combined packer is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A novel combined packer is designed, comprising a packer, a plate fixedly connected to one side of the outer wall of the packer, a shell fitted with a clearance fit to one side of the outer wall of the packer, an annular plate fixedly connected to the bottom of the inner wall of the shell on one side, a sponge sleeve fixedly connected to the inner wall of the annular plate, the inner wall of the sponge sleeve being in contact with one side of the outer wall of the packer, and a shielding structure provided on one side of the shell.

[0007] Preferably, the shielding structure includes a square rod, one side of the outer wall of the square rod is clearance-fitted with one side of the inner wall of the housing, one end of the square rod is fixedly connected to an inclined block, one side of the outer wall of the inclined block is clearance-fitted with a groove at one end of the plate, the outer wall of the square rod is clearance-fitted with a spring, the upper and lower ends of the spring are respectively fixedly connected to a groove on one side of the inner wall of the housing and one end of the inclined block, one side of the inclined block is provided with a rubber sleeve, the outer wall of the rubber sleeve is fixedly connected to one end of the inner wall of the housing, and the inner wall of the rubber sleeve is in contact with one side of the outer wall of the packer.

[0008] Preferably, an outer shell is fixedly connected to the top side of one side of the housing.

[0009] Preferably, a piston is threaded onto the top inner wall of the housing.

[0010] Preferably, a curved tube is fixedly connected to the inner wall of the top side of one side of the housing, and the lower part of the outer wall of the curved tube is fixedly connected to the inner wall of the top of the annular plate.

[0011] Preferably, a straight block is fixedly connected to one end of the inner wall of the outer shell.

[0012] The present invention proposes a novel combined packer with the following advantages: through the cooperation of the packer, the housing, and the shielding structure, the device can be used by inserting the housing into one side of the outer wall of the packer. The inclined surface of the plate causes the inclined block to move outward, and the inclined block compresses the spring. When the housing continues to move inward, the spring rebounds and drives the inclined block to move inward, so that the inclined block is inserted into the groove of the plate. This achieves the combined positioning of the housing and the packer. The rubber sleeve plays a sealing role, which facilitates the shielding and protection of the end of the packer, thereby preventing impurities from entering the packer and affecting normal use.

[0013] Through the cooperation of the housing, packer, outer shell, piston, curved tube, annular plate, and sponge sleeve, the device allows for the following operation: by rotating the piston, it can be removed, allowing lubricating oil to be injected into the interior of the outer shell. The lubricating oil flows downward through the curved tube, and the sponge sleeve absorbs the lubricating oil. When the housing is disassembled, one side of the housing moves the annular plate to the right, which in turn moves the sponge sleeve to the right, thus applying lubricating oil to the packer. This facilitates the application of lubricating oil to the threaded parts, preventing sticking during use. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings:

[0022] Example 1:

[0023] See attached document Figure 1-6 In this embodiment, a novel combined packer includes a packer 1. A plate 10 is fixedly connected to one side of the outer wall of the packer 1. A housing 3 is fitted with the outer wall of the packer 1 with clearance. An annular plate 4 is fixedly connected to the bottom of the inner wall of the housing 3 on one side. A sponge sleeve 5 is fixedly connected to the inner wall of the annular plate 4. The sponge sleeve 5 is used to absorb lubricating oil. The inner wall of the sponge sleeve 5 is in contact with one side of the outer wall of the packer 1.

[0024] A housing 7 is fixedly connected to the top of one side of the housing 3. A piston 8 is threadedly connected to the top inner wall of the housing 7. The piston 8 serves as a seal. A curved tube 6 is fixedly connected to the top inner wall of one side of the housing 3. The lower part of the outer wall of the curved tube 6 is fixedly connected to the top inner wall of the annular plate 4. A straight block 9 is fixedly connected to one end of the inner wall of the housing 7. A shielding structure 2 is provided on one side of the housing 3. The shielding structure 2 facilitates the shielding and protection of the end of the packer 1, thereby preventing impurities from entering the packer 1 and affecting normal use.

[0025] The shielding structure 2 includes a square rod 2a3. One side of the outer wall of the square rod 2a3 is in clearance fit with one side of the inner wall of the housing 3. The inner wall of one side of the housing 3 plays a limiting role when the square rod 2a3 moves up and down under force. One end of the square rod 2a3 is fixedly connected to a wedge block 2a2. One side of the outer wall of the wedge block 2a2 is in clearance fit with one end of the plate 10 groove. A spring 2a1 is in clearance fit with the outer wall of the square rod 2a3. The spring 2a1 applies an inward force to the wedge block 2a2.

[0026] The upper and lower ends of the spring 2a1 are fixedly connected to the groove on one side of the inner wall of the housing 3 and one end of the inclined block 2a2, respectively. A rubber sleeve 2a4 is provided on one side of the inclined block 2a2. The outer wall of the rubber sleeve 2a4 is fixedly connected to the inner wall of one end of the housing 3. The inner wall of the rubber sleeve 2a4 is in contact with one side of the outer wall of the packer 1, which facilitates the shielding and protection of the end of the packer 1, thereby preventing impurities from entering the packer 1 and affecting normal use.

[0027] Working principle:

[0028] When transporting or moving packer 1:

[0029] Insert the housing 3 into one side of the outer wall of the packer 1. The inclined surface of the plate 10 causes the inclined block 2a2 to move outward, compressing the spring 2a1. As the housing 3 continues to move inward, the spring 2a1 rebounds, causing the inclined block 2a2 to move inward, inserting it into the groove of the plate 10. This achieves the combined positioning of the housing 3 and the packer 1. The rubber sleeve 2a4 acts as a seal, preventing impurities from entering the packer 1 and affecting its normal use. Rotate the piston 8, remove the piston 8, and inject lubricating oil into it. Inside the outer casing 7, lubricating oil flows downward through the curved pipe 6. The sponge sleeve 5 absorbs the lubricating oil. When the packer 1 needs to be used, the square rod 2a3 is pulled outward. The square rod 2a3 drives the inclined block 2a2 to move outward, moving the inclined block 2a2 out of the groove of the plate 10. The outer casing 3 is then moved outward, thus disassembling the outer casing 3. At the same time, the outer casing 3 on one side drives the annular plate 4 to move to the right. The annular plate 4 drives the sponge sleeve 5 to move to the right, thus applying lubricating oil to the packer 1, making it easier to use the packer 1.

[0030] Example 2:

[0031] See attached document Figure 1-6 In this embodiment, a novel combined packer is provided, wherein the shielding structure 2 may further include a filter screen 2b1. One side of the outer wall of the filter screen 2b1 is in clearance fit with the inner wall of one end of the outer casing 7. The material and mesh size of the filter screen 2b1 are determined according to the actual use. A sealing sleeve is fixedly connected to the inner wall of one end of the outer casing 7. The inner wall of one end of the filter screen 2b1 is in clearance fit with the outer wall of the straight block 9. A curved block 2b2 is fixedly connected to the other end of the filter screen 2b1. The lower inner wall of the curved block 2b2 is threadedly connected to the inner wall of one end of the outer casing 7 by bolts.

[0032] Working principle:

[0033] When lubricating oil is injected into the interior of housing 7, filter screen 2b1 can filter impurities in the lubricating oil to prevent impurities from clogging the curved pipe 6.

[0034] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
