Description

Technical Field

[0001] This utility model relates to the field of radiation protection equipment technology, and in particular to a tungsten-based rubber pipe radiation shielding device with temperature monitoring function. Background Technology

[0002] In fields such as nuclear industry, radiation medicine, and high-energy physics research, pipelines are critical facilities for transporting radioactive fluids or gases. To ensure personnel safety and environmental stability, these pipelines must be effectively shielded against radiation. Traditionally, materials such as lead plates have been used for protection, but these are heavy, toxic, and lack flexibility, making installation inconvenient. In recent years, tungsten-based rubber composite materials, which combine excellent shielding performance with good flexibility, have been widely used. They can better fit the pipeline and are easier to install.

[0003] However, simply providing radiation shielding is insufficient to meet the demands of complex applications. The decay of radioactive materials within the pipeline or the fluid itself continuously generates heat, which is hindered by the outer shielding layer and difficult to dissipate effectively. This continuous accumulation of heat can create localized high temperatures, potentially affecting the stability of the transported medium, accelerating the aging of the shielding material itself, reducing its physical properties, and even damaging the pipeline structure in extreme cases, posing a safety hazard. Therefore, while providing radiation protection, real-time temperature monitoring and effective heat management of the pipeline become crucial.

[0004] Currently, existing pipeline shielding devices often prioritize shielding functionality in their structural design, employing simple clips or bolts for fastening. These structures typically have fixed dimensions and extremely limited adjustment range, resulting in poor versatility and difficulty adapting to pipes of different diameters or with manufacturing tolerances. More importantly, this fixed connection method makes installation and disassembly extremely cumbersome, especially during regular pipeline inspections or maintenance. Repeated disassembly and reassembly are not only inefficient but can also damage the shielding device itself, failing to meet the demands of modern industry for efficient and convenient operation.

[0005] Therefore, this utility model proposes a tungsten-based rubber pipe radiation shielding device with temperature monitoring function to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a tungsten-based rubber pipe radiation shielding device with temperature monitoring function. It aims to improve the problems of existing pipe radiation shielding devices, such as only having shielding function, being unable to monitor temperature in real time and actively dissipate heat, and being inconvenient to install and adjust and having poor versatility. This utility model aims to provide a tungsten-based rubber pipe radiation shielding device with temperature monitoring function with an improved structure that can effectively solve the above problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a tungsten-based rubber pipe radiation shielding device with temperature monitoring function, comprising: a shielding mechanism and a modular mechanism, the shielding mechanism defining a central channel for accommodating the monitoring pipe; a clamp in the shape of an open ring, the clamp surrounding and detachably fixing the shielding mechanism, the two ends of the opening of the clamp being integrally configured as a first connecting block and a second connecting block respectively; and an adjustment mechanism disposed between the first connecting block and the second connecting block.

[0008] The adjustment mechanism includes an adjustment chain fixedly connected to the second connecting block, and the adjustment chain meshes with an adjustment gear rotatably connected inside the first connecting block.

A pull ring is fixedly connected to the upper end of the connecting plate, and the side wall of the right-angle locking tongue is slidably fitted with a limiting plate fixed to the inner wall of the first connecting block.

[0010] Preferably, the shielding mechanism includes a tungsten-based rubber layer and a heat dissipation layer stacked sequentially from the inside out, and an embedded temperature sensor is provided inside the tungsten-based rubber layer.

[0011] Preferably, the heat dissipation layer has multiple heat dissipation fins integrally formed on the side of the heat dissipation layer facing away from the tungsten-based rubber layer.

[0012] Preferably, one end of the clamp is fixedly connected to a first connecting ring, and the other end of the clamp is fixedly connected to a second connecting ring; the outer wall of the heat dissipation layer is provided with a splicing groove that engages with the first connecting ring.

[0014] Preferably, the right-angle latch has a locking surface that abuts against the straight surface of the right-angle locking gear.

[0015] Preferably, the spring is a compression spring, and the two ends of the spring abut against the bottom surface of the right-angle latch and the inner wall of the first connecting block, respectively.

[0016] Preferably, the pull ring extends through the housing of the first connecting block and is used to drive the connecting plate and the right-angle locking tongue to move synchronously, so that the right-angle locking tongue disengages from the right-angle locking gear.

In this utility model, by setting a temperature sensor inside the tungsten-based rubber shielding layer and setting a heat dissipation layer on the outside, the problem that the existing pipeline shielding device only has a shielding function and cannot monitor temperature and actively dissipate heat, thus posing a safety hazard, is solved.

[0021] 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.

[0022] Please refer to Figures 1 to 5 This utility model provides a tungsten-based rubber pipe radiation shielding device with temperature monitoring function, which aims to solve the problems of existing pipe radiation shielding devices having single function, inability to monitor temperature in real time and actively dissipate heat, inconvenient installation and adjustment, and poor versatility.

[0023] like Figure 1 and Figure 2 As shown, the tungsten-based rubber pipe radiation shielding device with temperature monitoring function includes a shielding mechanism 1 and a modular mechanism 3, and the modular mechanism 3 surrounds and fixes the shielding mechanism 1. The shielding mechanism 1 defines a central channel for accommodating the monitoring pipe 101 and provides radiation shielding and temperature monitoring for the monitoring pipe 101. The modular mechanism 3 is used to lock the shielding mechanism 1 to the outer wall of the monitoring pipe 101. Specifically, the shielding mechanism 1 includes a hollow cylindrical tungsten-based rubber layer 102. The inner wall of the tungsten-based rubber layer 102 is used to fit the outer wall of the monitoring pipe 101. Multiple mounting grooves are opened inside the tungsten-based rubber layer 102. An embedded temperature sensor 104 is fixedly installed in the mounting groove of the tungsten-based rubber layer 102. The heat dissipation layer 103 is uniformly bonded and fixed to the outer wall of the tungsten-based rubber layer 102 through a thermally conductive silicone layer. The heat dissipation layer 103 faces the side away from the tungsten-based rubber layer 102. The surface is integrally formed with multiple heat dissipation fins; the core component of the modular mechanism 3 is the clamp 301, which is an open ring structure. The two ends of the opening of the clamp 301 are integrally set as the first connecting block 201 and the second connecting block 202, respectively. In order to realize the length splicing of the device, one end of the clamp 301 is fixedly connected to the first connecting ring 303, and the other end of the clamp 301 is fixedly connected to the second connecting ring 304. The outer wall of the heat dissipation layer 103 is provided with a splicing groove 302 that engages with the first connecting ring 303. The first connecting ring 303 of a shielding device is fixed by engaging with the splicing groove 302 of the heat dissipation layer 103. At the same time, when splicing is required, the first connecting ring 303 on the clamp 301 of the next shielding device can engage with the second connecting ring 304 on the clamp 301 of this shielding device, so that multiple shielding devices can be spliced ​​in series.

[0024] The adjusting mechanism 2 includes an adjusting chain 204. One end of the adjusting chain 204 is fixedly connected to the second connecting block 202, and the other end of the adjusting chain 204 passes through the first connecting block 201 and meshes with an adjusting gear 203 rotatably connected inside the first connecting block 201. The adjusting gear 203 is coaxially and fixedly connected to a right-angle locking gear 205 via a rotating shaft 210. One end of the rotating shaft 210 extends to the outside of the first connecting block 201 and is provided with a connecting hole 211 for rotatably connecting with an external rotating handle, thereby driving the adjusting gear 203 and the right-angle locking gear 205 to rotate synchronously. Inside the first connecting block 201, a right-angle locking tongue 206 is movably installed below the right-angle locking gear 205. The two ends of a spring 207 abut against the bottom surface of the right-angle locking tongue 206 and the first connecting block 201, respectively. The inner wall of the first connecting block 201 is continuously subjected to an upward elastic force by the spring 207 to push the right-angle locking tongue 206 to engage with the teeth of the right-angle locking gear 205. In order to unlock the right-angle locking tongue 206, a connecting plate 208 is fixedly connected to the upper end of the right-angle locking tongue 206, and a pull ring 209 is fixedly connected to the upper end of the connecting plate 208. The pull ring 209 protrudes from the housing of the first connecting block 201. In order to ensure the stability of the lifting and lowering movement of the right-angle locking tongue 206, a limiting plate 212 is fixedly connected to the inner wall of the first connecting block 201. The side wall of the right-angle locking tongue 206 slides against the side of the limiting plate 212. This linkage structure of the pull ring 209, the connecting plate 208 and the right-angle locking tongue 206 ensures that the right-angle locking tongue 206 can be quickly pulled away from the engagement with the right-angle locking gear 205, thereby unlocking the device.

[0025] In a preferred embodiment, in order to further improve the heat dissipation efficiency of the device, a plurality of heat dissipation fins extending along the device axis are integrally formed on the surface of the heat dissipation layer 103 facing away from the tungsten-based rubber layer 102. The heat dissipation fins increase the contact area between the heat dissipation layer 103 and the outside air.

[0026] As another preferred embodiment, in order to realize the modular splicing of the device to adapt to monitoring pipes 101 of different lengths, one end of the clamp 301 is fixedly connected to a first connecting ring 303, and the other end of the clamp 301 is fixedly connected to a second connecting ring 304; correspondingly, a splicing groove 302 that matches the shape and size of the first connecting ring 303 is provided on the outer wall of the heat dissipation layer 103.

[0027] As another preferred embodiment, in order to achieve a reliable one-way locking function of the adjusting mechanism 2, the teeth of the right-angle locking gear 205 have a specific asymmetrical shape. Each tooth includes an inclined surface for pressing and pushing the right-angle locking tongue 206 when rotating, and a straight surface for blocking the right-angle locking tongue 206 when reversing.

[0028] As a further limitation of the above-mentioned one-way locking structure, in order to ensure the stability and reliability of the locking, the right-angle locking tongue 206 has a locking surface that abuts against the straight surface of the right-angle locking gear 205. When the right-angle locking gear 205 attempts to rotate in the opposite direction, the two straight surfaces contact each other to form a rigid block.

[0029] As another preferred embodiment, in order to provide a continuous and stable engagement force to the right-angle locking tongue 206, the spring 207 is preferably a compression spring. The two ends of the spring 207 abut against the bottom surface of the right-angle locking tongue 206 and the inner wall of the first connecting block 201, respectively, and always apply a thrust to the right-angle locking tongue 206 to make it move toward the right-angle locking gear 205.

[0030] As another preferred embodiment, in order to achieve convenient unlocking operation, the pull ring 209 is fixedly connected to the right angle locking tongue 206 through the connecting plate 208, and the pull ring 209 extends out of the housing of the first connecting block 201. By pulling the pull ring 209 exposed to the outside, the operator can drive the connecting plate 208 and the right angle locking tongue 206 to move synchronously, thereby enabling the right angle locking tongue 206 to overcome the elastic force of the spring 207 and disengage from the right angle locking gear 205.

[0031] Working principle: When the device needs to be locked onto the monitoring pipe 101, the external rotating handle drives the rotating shaft 210 to rotate. The rotating shaft 210 drives the adjusting gear 203 and the right-angle locking gear 205 to rotate synchronously. The adjusting gear 203 meshes and tightens the adjusting chain 204, thereby pulling the second connecting block 202 closer to the first connecting block 201, thus tightening the clamp 301. At the same time as the clamp 301 tightens, the inclined surface of the right-angle locking gear 205 will press against the right-angle locking tongue 206, causing the right-angle locking tongue 206 to move downward against the elastic force of the spring 207. When the tip of the right-angle locking gear 205 passes the right-angle locking tongue 206, the spring 207 rebounds and pushes the right-angle locking tongue 206 into the next tooth gap, thus forming a one-way locking. If rotated in the opposite direction, the straight surface of the right-angle locking gear 205 will... The locking surfaces of the right-angle locking tongue 206 abut against each other and cannot rotate. When the device needs to be unlocked, the pull ring 209 located outside the first connecting block 201 is pulled upward. The pull ring 209 drives the right-angle locking tongue 206 to move downward through the connecting plate 208, and overcomes the elastic force of the spring 207, so that the locking surface of the right-angle locking tongue 206 completely disengages from the straight surface of the right-angle locking gear 205. At this time, the locking state is released, the adjusting chain 204 can be loosened, and the entire device can be disassembled from the monitoring pipe 101. During the operation of the device, the embedded temperature sensor 104 monitors the temperature of the monitoring pipe 101 in real time. The heat generated by the monitoring pipe 101 is conducted to the heat dissipation layer 103 through the tungsten-based rubber layer 102 and the thermally conductive silicone, and finally dissipated to the surrounding environment through the heat dissipation fins on the surface of the heat dissipation layer 103.
