Description

Technical Field

[0001] The utility model relates to the technical field of helium storage equipment, in particular to a high-purity helium storage device. Background Art

[0002] Helium is a colorless, odorless, highly inert rare gas that is widely present in the universe, but is relatively rare on Earth and difficult to extract directly. High-purity helium is helium that has undergone precise purification to remove almost all impurities. Its purity is extremely high. Due to its stable chemical properties, good thermal conductivity, and resistance to reaction with other substances, it is widely used in scientific research, medical treatment, semiconductor manufacturing, fiber optic communications, aerospace, cryogenic technology and other fields. It is one of the important resources indispensable for the development of modern industry and technology.

[0003] However, since most helium is stored in high-pressure cylinders for transportation, and existing cylinders are relatively small and lack external protective devices, when the helium is transported, external collisions can cause the high-pressure gas inside to accumulate, creating stress concentrations at the locations where the cylinders are impacted, which can easily cause the cylinders to break or explode, posing a certain safety hazard. Furthermore, due to the heavy weight of the cylinders, manual handling is often used to reduce collisions between cylinders, which wastes a lot of manpower and time, affecting handling efficiency. Therefore, those skilled in the art have provided a high-purity helium storage device to address the problems raised in the above-mentioned background technology. Utility Model Content

[0004] The purpose of the present invention is to provide a high-purity helium storage device to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] Preferably, a plurality of connecting plates are provided on the arc frame, two adjacent arc-shaped clamping rings are connected to each other through the connecting plates, and the arc frame is composed of a plurality of arc-shaped clamping rings and connecting plates.

[0008] Preferably, a clamping groove is provided inside the arc-shaped clamping ring, and the arc-shaped clamping ring is clamped to the outer wall of the gas cylinder through the clamping groove.

[0009] Preferably, a threaded hole is opened at a position corresponding to the side wall of the base and the threaded rod, the threaded rod is threadedly installed inside the threaded hole and extends to the outside of the base, and the internal threads of the limit nuts located on the inside and outside of the base are opposite to the internal threads of the threaded hole.

[0010] Preferably, a slider is provided at the bottom of the arc-shaped clamping ring located inside the slot, and a sliding groove is provided at a position on the inner wall of the slot corresponding to the slider, and the slider slides inside the sliding groove.

[0011] Preferably, a through hole is provided at a position of the side wall of the arc-shaped protective plate corresponding to the threaded rod, and the arc-shaped protective plate is sleeved on the outside of the threaded rod through the through hole.

[0012] Preferably, universal wheels are provided at the four bottom corners of the fixing frame, and the fixing frame contacts the ground through the universal wheels.

[0013] Compared with the prior art, the advantages of the present invention are:

[0014] By providing a fixing frame, when installing the gas cylinder, the gas cylinder can be inserted into the empty groove on the base, and the threaded rod in the threaded hole is screwed to move the threaded rod toward the inside of the empty groove, and the moving threaded rod pushes the arc frame connected to it to move in the empty groove, so that the arc-shaped clamping rings on the two arc frames are clamped on both sides of the gas cylinder through the clamping groove, and the gas cylinder is clamped between the arc-shaped clamping rings on the two arc frames for limiting, and the pressure sensor installed on the inner side wall of the arc-shaped clamping ring is attached to the outer wall of the gas cylinder for detection, and then the two limit nuts on the threaded rod are screwed to make the two limit nuts respectively close to the inner wall of the empty groove and the outer wall of the base, and tighten the threaded rod to limit the position of the threaded rod, thereby completing the limitation of the arc frame after the adjustment position, and the pressure sensor can detect the pressure generated by the change in the shape of the gas cylinder, and remind the staff of the pressure change in the gas cylinder, so that the staff can take timely measures to avoid the gas cylinder being stretched or exploded due to the increase and accumulation of pressure in the gas cylinder, thereby realizing the monitoring of the gas cylinder.

[0015] By setting up an arc frame, the gas cylinder is clamped and fixed between the two arc frames for limiting the position. The arc frame can be used to reinforce the gas cylinder, avoiding the trouble of the gas cylinder being easily stretched due to the small thickness of the gas cylinder, and improving the service life of the gas cylinder. Moreover, when the gas cylinder is hit by an external object, the arc-shaped protective plate can contact the external object, and the spring can then cushion the collision force on the arc-shaped protective plate, preventing the gas cylinder from contacting the external object and being affected by the collision of the external object, avoiding the situation where the gas pressure inside the gas cylinder accumulates and breaks the collision position due to the direct collision of the gas cylinder with the external object, thereby protecting the gas cylinder.

[0016] By arranging universal wheels at the bottom of the base, when transporting the gas cylinder, the universal wheels can be used to push the fixing frame to move, and the gas cylinder installed inside the fixing frame can be transported to the designated location to complete the transportation of the gas cylinder, reducing the trouble of manual transportation of the gas cylinder, saving time and effort, and improving transportation efficiency.

One end of the threaded rod 14 away from the arc-shaped retaining ring 121 is threadedly installed inside the base 11 and extends to the outside thereof, and the outer wall of the threaded rod 14 located on the inner and outer sides of the base 11 is provided with a limit nut 141. The two limit nuts 141 are threadedly installed on the outer wall of the threaded rod 14 and are respectively tightly attached to the inner wall of the empty groove 111 and the outer wall of the base 11. In addition, the interior of the empty groove 111 is located on the outer sides of the two arc-shaped frames 12 and is provided with an arc-shaped protective plate 15. The inner side wall of the arc-shaped protective plate 15 is provided with a spring 16 at the position corresponding to the plurality of arc-shaped retaining rings 121.

[0025] In one embodiment, when the gas cylinder 2 is installed in the fixing frame 1, the gas cylinder 2 can be inserted into the empty groove 111 on the base 11, and the threaded rod 14 in the threaded hole 113 is screwed to move the threaded rod 14 toward the inside of the empty groove 111. The moving threaded rod 14 then pushes the arc frame 12 connected thereto to move, so that the two arc frames 12 are close to each other in the empty groove 111 through the cooperation of the slider 124 and the slide groove 112, and the grooves 123 on the arc-shaped snap ring 121 are engaged with the two sides of the gas cylinder 2, so that the gas cylinder 2 is clamped between the arc-shaped snap rings 121 on the two arc-shaped frames 12 for limiting the position, so that the gas cylinder 2 installed in the fixing frame 1 The pressure sensor 13 on the inner wall of the arc-shaped retaining ring 121 is attached to the outer wall of the gas cylinder 2 for detection, and then the two limit nuts 141 on the threaded rod 14 are screwed, so that the two limit nuts 141 are respectively tightly attached to the inner wall of the empty groove 111 and the outer wall of the base 11 to tighten the threaded rod 14, limit the position of the threaded rod 14, and limit the arc-shaped frame 12 after the adjusted position, thereby completing the installation of the gas cylinder 2. The gas cylinder 2 can be reinforced by the arc-shaped frame 12, avoiding the trouble of the gas cylinder 2 being easily stretched due to the small thickness of the gas cylinder 2, thereby improving the service life of the gas cylinder 2 and realizing the protection of the gas cylinder 2.

[0026] In one embodiment, since the arc frame 12 is composed of a plurality of arc-shaped snap rings 121 and connecting plates 122, when the arc frame 12 is used to define the position of the gas cylinder 2, the threaded rod 14 in the threaded hole 113 can be screwed to allow the threaded rod 14 to move toward the inside of the empty groove 111, and then the moving threaded rod 14 pushes the arc-shaped snap ring 121 located in the empty groove 111 to move, and drives other arc-shaped snap rings 121 connected to it through the connecting plate 122 to move, so that the arc-shaped snap ring 121 is engaged with different positions of the gas cylinder 2 through the snap groove 123, clamping and fixing the gas cylinder 2 at different positions, preventing the gas cylinder 2 from tilting or shaking, and improving the stability of the installation of the gas cylinder 2. Moreover, since the arc-shaped protective plate 15 is sleeved on the outside of the threaded rod 14 through the through hole 151, when the threaded rod 14 is rotated to drive the arc frame 12 to move, the arc-shaped protective plate 15 will not interfere with the threaded rod 14, thereby ensuring the use of the arc-shaped protective plate 15.

[0027] In one embodiment, since the internal threads of the limiting nuts 141 located on the inner and outer sides of the base 11 are opposite to the internal threads of 131, when adjusting the position of the arc frame 12, the two limiting nuts 141 on the threaded rod 14 can be screwed, so that the two limiting nuts 141 are respectively tightly attached to the inner wall of the empty groove 111 and the outer wall of the base 11 to tighten the threaded rod 14, thereby limiting the position of the threaded rod 14 and preventing the threaded rod 14 from rotating in the threaded hole 113, thereby avoiding the situation where the arc frame 12 moves due to the rotation of the threaded rod 14 and causing the gas cylinder 2 to shake, thereby ensuring the stability of the installation of the gas cylinder 2.

[0028] In one embodiment, when helium is stored in the gas cylinder 2, the pressure generated by the deformation of the gas cylinder 2 can be detected by the pressure sensor 13. According to the pressure value generated by the deformation of the gas cylinder 2 detected by the pressure sensor 13, it is known whether the gas pressure inside the gas cylinder 2 exceeds the limit, and the staff is reminded that the pressure inside the gas cylinder 2 has changed, so that the staff can take timely measures to avoid the gas cylinder 2 being stretched or exploded due to the increase and accumulation of pressure inside the gas cylinder 2, thereby realizing the monitoring of the gas cylinder 2.

[0029] In one embodiment, when transporting the gas cylinder 2, the fixing frame 1 can be pushed to move by the universal wheel 17, and the gas cylinder 2 installed inside the fixing frame 1 can be transported to a designated location to complete the transportation of the gas cylinder 2, thereby reducing the trouble of manual transportation of the gas cylinder 2, saving time and effort, and improving transportation efficiency.

[0030] In one embodiment, when the gas cylinder 2 is hit, the arc-shaped protective plate 15 may first come into contact with the foreign object, and then the spring 16 may buffer the collision force exerted on the arc-shaped protective plate 15 to prevent the arc-shaped protective plate 15 from colliding with the gas cylinder 2, thereby preventing the gas cylinder 2 from being affected by the collision with the foreign object. This avoids the situation in which the gas cylinder 2 is directly hit by the foreign object and causes the gas pressure inside the gas cylinder 2 to accumulate and rupture the collision position, thereby protecting the gas cylinder 2.

[0031] The working principle of the utility model is as follows: when in use, the gas cylinder 2 can be inserted into the empty groove 111 on the base 11, and the threaded rod 14 in the threaded hole 113 can be screwed to allow the threaded rod 14 to move toward the inside of the empty groove 111. The moving threaded rod 14 pushes the arc frame 12 connected thereto to move, so that the two arc frames 12 are close to each other in the empty groove 111 through the cooperation of the slider 124 and the slide groove 112, and the snap groove 123 on the arc snap ring 121 is engaged with both sides of the gas cylinder 2, so that the gas cylinder 2 is clamped between the arc snap rings 121 on the two arc frames 12 for limiting. The pressure sensor 13 installed on the inner wall of the arc snap ring 121 is attached to the outer wall of the gas cylinder 2 for detection. Then, the two limiting nuts 141 on the threaded rod 14 are screwed, so that the two limiting nuts 141 are respectively attached to the inner wall of the empty groove 111 and the outer wall of the base 11, and the threaded rod 14 is tightened to limit the position of the threaded rod 14. The arc frame 12 is limited after the adjusted position is set, so as to complete the installation of the gas cylinder 2. The arc frame 12 can reinforce the gas cylinder 2, avoid the trouble of the gas cylinder 2 being easily stretched due to the small thickness of the gas cylinder 2, and improve the service life of the gas cylinder 2. The arc protection plate 15 contacts the external object, and the spring 16 cushions the collision force received by the arc protection plate 15, preventing the arc protection plate 15 from colliding with the gas cylinder 2, and preventing the gas cylinder 2 from being affected by the collision of the external object, avoiding the situation that the gas pressure inside the gas cylinder 2 is directly hit by the external object and breaking the collision position, thereby protecting the gas cylinder 2. Moreover, when transporting the gas cylinder 2, the universal wheel 17 can be used to push the fixing frame 1 to move, and the gas cylinder 2 installed in the fixing frame 1 can be transported to the designated place, completing the transportation of the gas cylinder 2, reducing the trouble of manual transportation of the gas cylinder 2, saving time and effort, and improving transportation efficiency.

Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
