[0040] The present invention will be further described below in conjunction with the specific implementation manners. It should be understood that these embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of this application.

[0041] Refer to Figures 1 to 6 , in specific embodiment 1, this embodiment 1 provides a sealing detection tool for a multi-hole oil pipe. One end of the multi-hole oil pipe 1 is provided with an oil inlet 1-2 at the pipe head, and a plurality of injection holes 1-3 are provided on the pipe body 1-1 of the multi-hole oil pipe 1. The sealing detection tool includes a bottom plate 2. A floating lower module 3 for supporting the multi-hole oil pipe 1 and sealing the injection holes 1-3 and a sealing group 4 for inflating the oil inlet 1-2 and sealing the oil inlet 1-2 when inflating are provided on the bottom plate 2. An upper module 5 for pressing the multi-hole oil pipe 1 is fixed on the bottom plate 2 through a bracket group 6.

[0042] The floating lower module 3 includes a substrate 3-3 and a plurality of lower pressing blocks 3-1. The lower pressing blocks 3-1 are arranged on the substrate 3-3. The bottom of the substrate 3-3 is connected to the bottom plate 2 through an elastic member 3-2. For example, the elastic member 3-2 is a spring; when the floating lower module 3 and the upper module 5 press the pipe body 1-1 of the multi-hole oil pipe 1, the elastic member 3-2 can elastically support the substrate 3-3, so that the lower pressing blocks 3-1 on the substrate 3-3 and the upper pressing block 5-2 clamp the multi-hole oil pipe 1 adaptively together, which can not only meet the requirement of the floating lower module 3 and the upper module 5 pressing the multi-hole oil pipe 1, but also effectively avoid the floating lower module 3 and the upper module 5 pressing too tightly, resulting in the multi-hole oil pipe 1 being damaged.

[0043] A number of lower pressing blocks 3-1 are arranged according to the shape of the pipe body 1-1 of the porous oil pipe 1. The top of the lower pressing block 3-1 is provided with a lower arc groove 3-4 that matches the shape of the pipe body 1-1 of the porous oil pipe 1. A soft sealing member 3-5 for sealing the injection holes 1-3 on the pipe body 1-1 is arranged in the arc groove. For example, the soft sealing member 3-5 is a rubber ring.

[0044] The lower pressing block 3-1 is provided with a positioning block 3-6 for positioning the porous oil pipe 1. The positioning block 3-6 corresponds to the other ends of the porous oil pipe 1 except the oil inlet 1-2.

[0045] The bracket group 6 includes a mounting column 6-1. The top of the mounting column 6-1 is provided with a first mounting plate 6-2. The first mounting plate 6-2 is provided with a first driving mechanism 6-3. The movable end of the first driving mechanism 6-3 is connected to a second mounting plate 6-4. The second mounting plate 6-4 is provided with a guide sleeve 6-5. The guide sleeve 6-5 is sleeved on the mounting column 6-1. The second mounting plate 6-4 drives the upper pressing block 5-2 to move up and down along the guide post under the drive of the first driving mechanism 6-3. For example, the first driving mechanism 6-3 is a first air cylinder. The upper die set 5 includes a third mounting plate 5-1. The bottom of the third mounting plate 5-1 is provided with a number of upper pressing blocks 5-2. The positions of the upper pressing blocks 5-2 correspond to the positions of the lower pressing blocks 3-1. The bottom of the upper pressing block 5-2 is provided with an upper arc groove 5-3 that matches the shape of the pipe body 1-1 of the porous oil pipe 1. The top of the third mounting plate 5-1 is connected to the bottom of the second mounting plate 6-4. At this time, using the same air cylinder (i.e., the first driving mechanism 6-3), a number of upper pressing blocks 5-2 are synchronously driven to move up and down, maintaining the synchronism of the number of upper pressing blocks 5-2, and ensuring that a number of upper pressing blocks 5-2 can all be evenly pressed on the pipe body 1-1 of the porous oil pipe 1.

[0046] The bottom plate 2 is also provided with a limiting rod 2-1 for limiting the height of the second mounting plate 6-4, preventing the second mounting plate 6-4 from being overly pressed down and causing the lower pressing block 3-1 to damage the porous oil pipe 1.

[0047] The top of the limiting rod 2-1 is provided with a screw 2-2 with adjustable height, realizing the adjustable height function of the limiting rod 2-1 to meet porous oil pipes 1 with different pipe diameters.

[0048] The plugging group 4 includes a second driving mechanism 4-1, which is fixed on the bottom plate 2 through a second fixing seat 4-2. The movable end of the second driving mechanism 4-1 is connected to a second connecting plate 4-3, and the second connecting plate 4-3 is connected to an outer plugging member 4-4. The outer plugging member 4-4 includes a sealing member 4-4-1 and an air outlet 4-4-2 for inflating the oil inlet 1-2. One end of the porous oil pipe 1 corresponding to the oil inlet 1-2 is embedded in the sealing member 4-4-1 and blocked by the sealing member 4-4-1. The oil inlet 1-2 corresponds to the air outlet 4-4-2, and gas is filled into the oil inlet 1-2 through the air outlet 4-4-2. For example, the second driving mechanism 4-1 is a second cylinder. The sealing member 4-4-1 is a sealing rubber ring, and the periphery of the air outlet 4-4-2 is surrounded by a sealing rubber ring. The air outlet 4-4-2 is connected to an external air source, and the gas pressure sensor detects the gas pressure in the porous oil pipe. Whether the porous oil pipe leaks is judged according to the change of the gas pressure. It has strong operability and is easy to use.

[0049] The second driving mechanism 4-1 is connected to the middle of the second fixing seat 4-2. A guide hole 4-5 is provided at each of the parts of the second fixing seat 4-2 above and below the second driving mechanism 4-1. The direction of the guide hole 4-5 is parallel to the telescopic direction of the movable end of the second driving mechanism 4-1. The second connecting plate 4-3 is provided with two upper and lower guide rods 4-6 on the side facing the second driving mechanism 4-1. The two guide rods 4-6 are matched with the two guide holes 4-5 one by one. The design of the upper and lower groups of guide holes 4-5 and guide rods 4-6 can ensure a more stable guiding effect and ensure that the translation trajectory of the second connection is more stable. In this way, the sealing member 4-4-1 of the plugging group 4 accurately wraps the end pipe head of the porous oil pipe 1 corresponding to the oil inlet 1-2, and at the same time, the air outlet 4-4-2 of the plugging group 4 can be more accurately aligned with the oil inlet 1-2, realizing the inflation of the plugging member into the oil inlet 1-2, and the gas filled will not overflow from the plugging member and all enter the oil inlet 1-2, improving the accuracy and detection efficiency of the sealing detection of the porous oil pipe 1 by the sealing detection tool for the porous oil pipe 1 in this Embodiment 1.

[0050] One side of the second connecting plate 4-3 facing the floating lower module 3 is connected to the outer plugging member 4-4, and the other side of the second connecting plate 4-3 facing away from the floating lower module 3 is connected to the movable end of the second driving mechanism 4-1, making more reasonable use of space.

[0051] Preferably, the second connecting plate 4-3 is a Z-shaped plate. The inner sides of the two horizontal plates in the Z-shaped plate are respectively connected to the movable end of the second driving mechanism 4-1 and the outer plugging member 4-4, making the space arrangement more reasonable and minimizing the lateral space area occupied by the bottom plate 2.

[0052] One side of the bottom plate 2 is provided with a V-shaped positioning groove 2-3. When the sealing detection tooling for the porous oil pipe 1 in this Embodiment 1 is used, the V-shaped positioning groove 2-3 can be used in cooperation with the corresponding convex blocks of other toolings to limit the position of the bottom plate 2 and prevent the bottom plate 2 from moving (i.e., positioning the position of the bottom plate 2 on a plane), ensuring the stability of the entire tooling.

[0053] Two handles 2-4 are provided on each side of the bottom plate 2, which is convenient for the overall handling of the sealing detection tooling for the porous oil pipe 1.

[0054] The specific use steps of the sealing detection tooling for the porous oil pipe 1 in this Embodiment 1 are as follows: First, place the porous oil pipe 1 in the lower arc groove 3-4 of the lower pressing block 3-1, so that the oil inlet 1-2 corresponds to the plugging group 4, ensuring that when the plugging group 4 seals the oil inlet 1-2, the air outlet 4-4-2 of the plugging group 4 can inflate the oil inlet 1-2 without leakage. Secondly, the first driving mechanism 6-3 controls the second mounting plate 6-4 and the third mounting plate to drive the lower pressing block 3-1 to move downward along the guide post until the second mounting plate 6-4 abuts against the top of the limit rod 2-1, and the lower arc groove 3-4 of the lower pressing block 3-1 presses tightly on the pipe body 1-1 of the porous oil pipe 1. At this time, the soft plugging member 3-5 in the lower arc groove 3-4 plugs all the injection holes 1-3 of the porous oil pipe 1. Thirdly, the second driving mechanism 4-1 controls the second connecting plate 4-3 to translate, and the second connecting plate 4-3 drives the plugging group 4 to move until the oil inlet 1-2 corresponds to one end of the porous oil pipe 1 and the pipe head is embedded in the sealing member 4-4-1 and is sealed by the sealing member 4-4-1. At the same time, the air outlet 4-4-2 of the plugging group 4 is aligned with the oil inlet 1-2 for inflation, so that the gas does not leak, ensuring the accuracy of the sealing detection tooling for the porous oil pipe 1. The second driving mechanism 4-1 drives the plugging group 4 to cooperate with the positioning block 3-6 of the lower pressing block 3-1 to clamp the porous oil pipe 1 on a plane together, facilitating the embedding of the oil inlet 1-2 corresponding to one end of the porous oil pipe 1 into the sealing member 4-4-1. Inflate the porous oil pipe through the air outlet 4-4-2 of the plugging group 4, and judge whether the porous oil pipe leaks according to the change of gas pressure. It has strong operability and is easy to use.

[0055] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be included in the patent protection scope of the present invention by the same token.
