A structure for sealing openings in radiation-proof walls

Abstract

This invention provides a wall opening sealing structure for radiation protection, relating to the field of wall wiring sealing technology. It includes an installation sleeve with a lead-sheathed sealing element installed on it. The lead-sheathed sealing element is used to conform to the wall. A bending and passing element is installed on the installation sleeve to allow cables to pass through the wall. A sealing and fixing element is installed on the installation sleeve. By using the bending control element in conjunction with the sealing and fixing element, it is convenient to first pass the cable through the lead pipe and then quickly control the bending of the lead pipe, ensuring radiation protection quality. This facilitates the initial cable passage through the lead pipe, and the bending control element allows for subsequent straightening of the lead pipe, enabling the removal of the cable inside. This solves the problems of current wall opening sealing structures where thicker cables are difficult to pass through, and where forcibly pushing cables through can easily damage them, making it inconvenient to pass the cable through first and then bend it.

Description

Technical Field

[0001] This invention relates to the field of wall wiring sealing technology, and more particularly to a structure for sealing openings in radiation-proof walls. Background Technology

[0002] Radiation shielding walls are widely used in the protection of spaces with radiation. They are typically constructed by covering concrete walls with lead sheets for radiation protection. During the construction of radiation shielding walls, openings are usually reserved to facilitate the passage of cables or pipes. Lead conduits are usually used for wiring and to seal the openings in the walls.

[0003] For example, utility model application CN201821498450.8 relates to a neutron radiation shielding sleeve and wall. The neutron radiation shielding sleeve includes a wall-penetrating section installed within the wall. At least a portion of the sleeve between the two ends of the wall-penetrating section is a bent section, preventing the two ends of the wall-penetrating section from being directly connected in the straight direction. Because of the bent section, the neutron radiation in this application is blocked in the straight direction, causing the neutron radiation to attenuate rapidly. Therefore, in actual construction, using this neutron radiation shielding sleeve as a wall-penetrating pipe in the walls of radiation-proof buildings reduces the risk of neutron radiation leakage from the pipe's ports.

[0004] Current wall opening sealing structures are ineffective at blocking radiation. To achieve the desired radiation protection, it is usually necessary to bend the conduit for wiring. However, bending the conduit makes it difficult to pass through thicker cables. Forcing the cable through can easily damage the cable and even the conduit itself, making it inconvenient to thread the cable first and then bend the conduit. At the same time, traditional opening sealing methods are not convenient for quickly sealing the wiring holes when maintenance is required, which can easily lead to radiation protection failure and poor safety.

It also facilitates the initial passing of the cable through the lead pipe 303, and at the same time utilizes the bending... The bending control component 5 facilitates subsequent re-straightening of the lead pipe 303 and disassembly of the cable inside the lead pipe 303. It is simple to operate and convenient to maintain. At the same time, this structure can be quickly controlled externally via the wrench drive shaft 404 without removing the fixing sleeve 101 from the wall, making it more suitable for working with thicker cables passing through walls. First, the cable is passed through the lead pipe 303. At this time, the wrench drive shaft 404 can be rotated. The bevel gear at the end of the wrench drive shaft 404 drives the bevel gear at the top of the bending threaded rod 501, which drives the bending threaded rod 501 to rotate. This drives the lifting block 502 to move the bending sleeve 503 upward, thereby bending the cable and the lead pipe 303 to prevent radiation leakage.

[0040] In Example 2, based on Example 1, the sleeve fastener 6 includes: a fastening threaded ring 601 and a compression threaded sleeve 602. The fastening threaded ring 601 is fixedly installed on the closed fixing cover 401; the compression threaded sleeve 602 is threadedly connected to the fastening threaded ring 601; the inner side of the compression threaded sleeve 602 has a beveled structure; the compression threaded sleeve 602 is located outside the rubber sleeve 302; the sleeve fastener 6 also includes: a rubber ring 603, which is fixedly installed on the closed fixing cover 401; the outer side of the rubber ring 603 has a beveled structure; the inner bevel of the compression threaded sleeve 602 is pressed and adhered to the rubber ring 603; the rubber ring 603 is sleeved on the rubber sleeve 302. Using the sleeve fastener 6 facilitates the fixing of the cable after the cable and lead pipe 303 are bent, which can maintain the stability of the cable and also improve the sealing effect of the structure. The structure is simple to operate, and the rubber ring 603 can be contracted inward to tightly fit the cable.

[0041] The working principle of this embodiment is as follows: First, the concrete layer 102 is inserted into the opening of the radiation-proof wall. The end of the lead sheet cover 201 is placed against the lead sheet surface of the radiation-proof wall. At this time, the fastening ring 402 can be manually threaded onto the sealing cover 401 to ensure that the fastening ring 402 is tightly attached to the radiation-proof wall. The sleeve 1 is then installed in a fixed position. After that, normal decoration and painting work can be carried out on the radiation-proof wall. When it is necessary to install cables through the wall, the cables are first passed through the lead pipe 303. At this time, the wrench drive shaft 404 can be rotated. The bevel gear at the end of the wrench drive shaft 404 drives the bevel gear at the top of the bending threaded rod 501, which drives the bending threaded rod 501 to rotate, driving the lifting block 502 to rise. At this time, the lifting sleeve 5021 is at the wrench drive shaft 404. 04 Slides upward, thereby causing the bending sleeve 503 to move upward. At this time, the cable will be stopped by the fixed sleeve 101 and the closed fixed cover 401. Only the area between the fixed sleeve 101 and the closed fixed cover 401 can be pulled upward. At this time, the rubber sleeve 302 will also slide on the closed fixed cover 401, realizing the bending of the cable and the lead pipe 303 to prevent radiation leakage. At the same time, when the cable needs to be pulled out later, the bending sleeve 503 can be directly controlled to move down and reset, and the lead pipe 303 can be straightened to facilitate the cable extraction. When the cable needs to be positioned, the compression threaded sleeve 602 can be manually rotated to move the compression rubber ring 603. The rubber ring 603 is squeezed by the inner inclined surface of the compression threaded sleeve 602. At this time, the rubber ring 603 is compressed and can retract inward to clamp the cable.

[0042] When the cable inside the lead pipe 303 is pulled out for maintenance or when no cable passes through the lead pipe 303, if there is still radiation equipment that needs to be operated, the shielding lead plate 202 can be rotated to shield the threaded hole on the fixing sleeve 101 to ensure the quality of radiation protection.
