Description

Technical Field

[0001] This utility model relates to the field of pipeline pre-embedding technology, specifically to a pipeline pre-embedding positioning structure for medical radiation protection engineering. Background Technology

[0002] In medical radiation protection engineering (such as linear accelerator treatment rooms and radiology departments), pipeline pre-installation is a crucial step in ensuring the safe operation of equipment and radiation protection. However, traditional pre-installation techniques have certain shortcomings and are difficult to meet the protection requirements of modern medical buildings. Specific problems are as follows:

[0003] In existing technologies, when pipelines pass through radiation shielding layers (such as lead plates), they are usually vertically pre-buried or simply sealed. The gap between the pipeline and the shielding layer lacks a systematic seal, and radiation can easily leak through the gap. Non-lead pipelines (such as PVC pipes) do not have radiation shielding capabilities, and the connection points with the shielding layer are prone to forming "shielding breaks", which increases the risk of radiation leakage.

[0004] In addition, when new medical equipment is added to the computer room (such as when additional cables are needed to upgrade radiotherapy equipment), the traditional pre-buried solution is inconvenient for adding cables.

[0005] Based on this, this utility model proposes a pre-embedded positioning structure for pipelines in medical radiation protection engineering. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a pre-embedded positioning structure for pipelines in medical radiation protection engineering.

[0007] The technical solution adopted in this utility model is as follows:

[0008] A pre-embedded positioning structure for medical radiation protection engineering pipelines includes: a pipe body with a parallelogram-shaped longitudinal section, cast at an incline into a building wall; a fixing mechanism, fixedly connected to the pipe body at both ends and to the building wall; a sealing mechanism, detachably and sealingly connected to the fixing mechanism, used to seal the pipe body at both ends; and a cable fixing mechanism, installed on the sealing mechanism, comprising: a conduit, which is connected to the interior of the pipe body for cable passage, the gap between the cable and the conduit being filled with a sealing layer; and a cap, which is installed on the conduit where no cable passes through.

[0009] The fixing mechanism includes: a fixing plate, which is U-shaped and fixedly connected to the pipe opening of the pipe body; and a screw, which is fixedly connected to the four corners of the fixing plate, with both ends of the screw protruding from the fixing plate, one end of which is fixedly connected to the building wall.

[0010] The fixing mechanism also includes anchoring claw bars, and multiple anchoring claw bars are fixedly connected around the perimeter of the pipe body for connection with the reinforcing steel skeleton.

[0011] The sealing mechanism includes: a sealing frame, on which a connecting hole corresponding to the screw is provided, the screw passes through the connecting hole, and the sealing frame is fixed to the fixing plate by a nut; and a sealing gasket, on which a U-shaped groove is provided at the bottom of the sealing frame, and a U-shaped protrusion is provided on the sealing gasket to match the U-shaped groove, the sealing gasket being fixedly connected to the U-shaped groove of the sealing frame and connected between the sealing frame and the fixing plate.

[0012] The sealing frame and the sealing gasket are provided with connection ports that are compatible with the conduit, and the conduit is fixedly connected to the connection port.

[0013] The sealing layer is composed of a composite filler of compressed lead beads and nano-tungsten powder.

[0014] The plug is coated with molybdenum disulfide on its inner thread, and a sealing gasket is provided inside the plug.

[0015] The pipe body, the fixing plate, the conduit, the plug, and the sealing frame are all made of lead plate.

[0016] Both the sealing gasket and the sealing pad include a lead body, and the lead body is provided with a rubber layer on the outside.

[0017] The beneficial effects of this utility model are:

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] like Figures 1-5 As shown in the figure, a pre-embedded positioning structure for medical radiation protection engineering pipelines according to an embodiment of the present invention may include a pipe body 10, a fixing mechanism 20, a sealing mechanism 30, and a cable fixing mechanism 40.

[0032] The pipe body 10 has a parallelogram-shaped longitudinal section and is cast at an angle into the building wall for pipeline installation. A fixing mechanism 20 is fixedly connected to the pipe openings at both ends of the pipe body 10 and to the building wall. A sealing mechanism 30 is detachably and sealingly connected to the fixing mechanism 20 to seal the pipe openings at both ends of the pipe body 10. A cable fixing mechanism 40 is installed on the sealing mechanism 30 and may include a conduit 41 and a cap 43. The conduit 41 is connected to the interior of the pipe body 10 for cable passage, and the gap between the cable and the conduit 41 is filled with a sealing layer 42. Caps 43 are installed on conduits 41 where no cable passes through. Multiple conduits 41 are arranged in an array on the sealing frame 31.

[0033] In this utility model, the tube body 10 is made of lead plate rolled and welded. The thickness of the lead plate can be set to 8-12mm. Its longitudinal section is a parallelogram. This tilt angle design can make the radiation form multiple reflections and attenuation in the tube body 10. Compared with the vertical pre-embedded structure, it can reduce the amount of radiation leakage.

[0034] When the tube body 10 is pre-embedded, the angle between its axis and the building wall can be set to 45°, and it is fixed to the concrete wall by inclined casting. For example, in the construction of the protective wall of the linear accelerator treatment room, the tilt direction of the tube body 10 needs to be away from the radiation source to ensure that the incident direction of the radiation forms an obtuse angle with the axis of the tube body 10, further enhancing the shielding effect.

[0035] like Figure 2 and Figure 3 As shown, in one embodiment of the present invention, the fixing mechanism 20 may include a fixing plate 21 and a screw 22. The fixing plate 21 is U-shaped and is fixedly connected to the pipe opening of the pipe body 10. The screw 22 is fixedly connected to the four corners of the fixing plate 21, and both ends of the screw 22 protrude from the fixing plate 21, with one end being fixedly connected to the building wall.

[0036] like Figure 3 As shown, in one embodiment of the present invention, the fixing mechanism 20 further includes anchoring claw bars 23, and a plurality of anchoring claw bars 23 are fixedly connected around the pipe body 10 for connection with the steel reinforcement skeleton.

[0037] The fixing plate 21 can be made of 10mm thick lead plate cut into a U-shaped frame. Its inner edge is welded to the pipe opening of the pipe body 10. The weld seam is fully welded with lead welding rod to ensure no radiation leakage gaps.

[0038] The screw 22 can be made of M12 stainless steel, with one end fixed to the concrete structure of the building wall and the other end used to connect to the sealing mechanism 30.

[0039] The anchoring claw bars 23 can be made of lead alloy claw-shaped steel bars with a diameter of 8mm, and 4-6 bars are evenly welded to each side of the outer perimeter of the pipe body 10. The ends of the claw bars are bent at 90° and fixed to the steel reinforcement skeleton inside the building wall (e.g., the main reinforcement in the steel reinforcement skeleton) by binding wire or spot welding to reduce the displacement of the pipe body 10 during the concrete pouring process.

[0040] like Figure 1 and Figure 3As shown, in one embodiment of this utility model, the sealing mechanism 30 may include a sealing frame 31 and a sealing gasket 32. The sealing frame 31 is provided with a connecting hole corresponding to the screw 22. The screw 22 passes through the connecting hole and the sealing frame 31 is fixed to the fixing plate 21 by a nut. The bottom of the sealing frame 31 is provided with a U-shaped groove. The sealing gasket 32 ​​is provided with a U-shaped protrusion 33 that matches the U-shaped groove. The sealing gasket 32 ​​is fixedly connected to the U-shaped groove of the sealing frame 31 and is connected between the sealing frame 31 and the fixing plate 21.

[0041] In this embodiment of the utility model, the sealing frame 31 can be made of 8mm lead plate, with a connection hole adapted to the screw 22. The edges of the connection hole can be rounded to avoid scratching the sealing gasket 32. The depth of the U-shaped groove at the bottom of the sealing frame 31 can be set to 4mm and the width to 10mm, forming an interference fit with the U-shaped protrusion 33 of the sealing gasket 32.

[0042] The lead body 441 of the sealing gasket 32 ​​can be set to a thickness of 3mm, and is externally wrapped with a 1mm thick neoprene rubber layer 442. During installation, the sealing gasket 32 ​​is first embedded into the U-shaped groove of the sealing frame 31. Furthermore, the sealing gasket 32 ​​and the sealing frame 31 can be bonded and fixed together. It should also be noted that the diameter of the U-shaped groove is larger than the diameter of the tube body 10. The sealing gasket 32 ​​is installed between the sealing frame 31 and the fixing plate 21, and tightened by the nut on the screw 22, causing the rubber layer 442 to deform under pressure, filling the gap between the sealing frame 31 and the fixing plate 21, thus improving airtightness.

[0043] like Figure 3 As shown, in one embodiment of this utility model, the sealing frame 31 and the sealing gasket are provided with a connection port 34 adapted to the conduit 41, and the conduit 41 is fixedly connected to the connection port 34. The conduit 41 is fixed to the connection port 34 by lead welding, and the weld height is ≥2mm.

[0044] like Figure 4 As shown, in one embodiment of this utility model, the sealing layer 42 is composed of a composite filler of compressed lead beads and nano-tungsten powder.

[0045] The conduit 41 is a lead pipe. After the cable passes through the conduit 41, the gap is filled with a composite filler of compressed lead beads and nano tungsten powder (mass ratio 3:1), with a filling density ≥11g / cm³. It is compacted in layers using a special compaction tool to ensure that there are no gaps in the filler. In addition, when installing the cable, a certain length of the cable is reserved inside the conduit 10, and the sealing mechanism 30 can be removed from both ends of the conduit 10.

[0046] In one embodiment of this utility model, the inner thread of the plug cap 43 is coated with a molybdenum disulfide coating, and a sealing gasket 44 is provided inside the plug cap 43.

[0047] The inner wall of the plug cap 43 is coated with a molybdenum disulfide coating, the thickness of which can be set to 20-30μm, to reduce the frictional torque when tightening. At the same time, a 3mm thick lead rubber sealing gasket 44 can be installed inside. The edge of the gasket adopts a lip design. When the plug cap 43 is tightened, the lip expands under pressure, realizing the sealing of the conduit 41 through which no cable passes, and improving the radiation shielding efficiency.

[0048] When threading cables, lead-based grease can be applied to the inside of the conduit 41 first. After the cable passes through, the sealing layer 42 is filled in. For the unthreaded conduit 41, a cap 43 is installed.

[0049] In one embodiment of this utility model, the pipe body 10, the fixing plate 21, the conduit 41, the plug cap 43, and the sealing frame 31 are all made of lead plate.

[0050] like Figure 5 As shown, in one embodiment of this utility model, both the sealing gasket 32 ​​and the sealing gasket 44 include a lead body 441, and a rubber layer 442 is provided on the outside of the lead body 441. The rubber layer 442 can be made of neoprene rubber, which has good sealing properties and flexibility. Wrapped around the lead body 441, it can fill gaps and adapt to certain deformations, enhancing the sealing effect, while also possessing certain weather resistance and corrosion resistance.
