Description

Technical Field

[0001] This utility model relates to the field of shielding wall technology, specifically a shielding wall anti-leakage device based on BNCT. Background Technology

[0002] In today's medical and scientific research fields, boron neutron capture therapy (BNCT) is receiving increasing attention as a highly promising advanced treatment. BNCT generates high-energy neutrons and various types of radiation during its implementation. Without proper protection, this radiation may leak into the surrounding environment, posing a serious health threat to medical personnel, patients, and the public. Therefore, BNCT equipment typically needs to be operated within a specific shielded space. However, BNCT-based shielding walls can age and crack after prolonged use, necessitating the use of leak-proof devices to seal them.

[0003] Based on the above, the inventors have discovered the following problems: the current BNCT-based shielded wall leak prevention device has poor adhesion to the wall during use, resulting in poor sealing effect and easily threatening human health.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a BNCT-based shielded wall leakage prevention device in order to achieve a more practical value. Utility Model Content

[0005] The purpose of this invention is to provide a BNCT-based shielded wall leak prevention device to solve the problem mentioned in the background art that the current BNCT-based shielded wall leak prevention devices have poor adhesion to the wall during use, resulting in poor sealing effect and easily threatening human health.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A BNCT-based shielded wall leak-proof device includes a base plate, a vertical plate mounted on the top center of the base plate, a shielding plate on one side of the base plate, and a translational fitting mechanism on the side of the vertical plate near the shielding plate. The translational fitting mechanism includes a bidirectional threaded rod, a retaining seat rotatably connected to the top of the bidirectional threaded rod, a bottom end of the bidirectional threaded rod rotatably connected to the top of the base plate, a side of the retaining seat fixedly connected to the top of the vertical plate near the shielding plate, sliders mounted on both ends of the bidirectional threaded rod, a first hinge mounted on one end of the slider, a connecting arm mounted on one end of the first hinge, a second hinge mounted on one end of the connecting arm, a connecting block mounted on one end of the second hinge, and a fixedly connected end of the connecting block to one side of the shielding plate. An adjusting rod rotatably connected to one side of the top of the base plate has a handle mounted on its top. Sprockets are mounted on the outer bottom ends of the adjusting rod and the bidirectional threaded rod, and chains are mounted on the outer sides of a pair of sprockets.

[0008] Furthermore, a pair of limiting rods are slidably connected inside the slider, with the top end of the limiting rods fixedly connected to the inside of the retaining seat, and the bottom end of the limiting rods fixedly connected to the top end of the base plate.

[0009] The beneficial effect of adopting the above-mentioned further solution is that, through the internal sliding connection of a pair of limiting rods, the slider maintains a stable direction during movement, avoiding deviation or shaking, thereby ensuring the smooth and accurate movement of the shielding plate and improving the reliability of the device.

[0010] Furthermore, an opening is provided at the center of the bottom end of the upright plate.

[0011] The advantage of adopting the above-mentioned further solution is that an opening is provided at the bottom center of the upright plate, which facilitates the passage of the chain.

[0012] Furthermore, each of the four corners of the upright plate near the shielding plate is equipped with a telescopic rod, one end of which is fixedly connected to one side of the shielding plate.

[0013] The beneficial effect of adopting the above-mentioned further solution is that by installing telescopic rods at all four corners on the side of the upright plate near the shielding plate, the movement stability of the shielding plate is improved.

[0014] Furthermore, a pair of reinforcing frames are installed on the side of the upright plate away from the shielding plate, and the bottom end of the reinforcing frames is fixedly connected to the top end of the base plate.

[0015] The beneficial effect of adopting the above-mentioned further solution is that by installing a pair of reinforcing frames on the side of the upright plate away from the shielding plate, the structural stability of the upright plate is improved.

[0016] Furthermore, the shielding plate is made of a flexible material.

[0017] The advantage of adopting the above-mentioned further solution is that by using a flexible material for the shielding plate, the fit is improved.

[0018] Furthermore, fixing holes are provided at the four corners of the top of the base plate.

[0019] The beneficial effect of adopting the above-mentioned further solution is that, with fixing holes at all four corners of the top of the base plate, the entire device can be easily fixed in the required position, ensuring that the device will not move or shake during use, thereby improving the stability and reliability of the device.

[0020] Compared with existing technologies, the beneficial effects of this utility model are as follows: This BNCT-based shielding wall leak-proof device, through the cooperation of the bidirectional threaded rod, slider, and connecting arm in the translation and bonding mechanism, allows the position of the shielding plate to be adjusted by rotating the bidirectional threaded rod, enabling it to better fit the area to be protected and improve the leak-proof effect. A chain is mounted on the outer side of a pair of sprockets, allowing the adjusting rod to rotate by rotating the handle. A pair of limiting rods are slidably connected inside the slider, ensuring the slider maintains a stable direction during movement and preventing deviation or wobbling. This ensures the smooth and accurate movement of the shielding plate and improves the device's performance. For reliability, an opening is provided at the bottom center of the upright plate to facilitate chain passage. Telescopic rods are installed at all four corners of the upright plate near the shielding plate to improve the stability of the shielding plate's movement. A pair of reinforcing frames are installed on the side of the upright plate away from the shielding plate to improve the structural stability of the upright plate. The shielding plate is made of flexible material to improve fit. Fixing holes are provided at all four corners of the top of the base plate to easily fix the entire device in the required position, ensuring that the device will not move or shake during use, thus improving the stability and reliability of the device. This utility model can effectively improve the fit between the shielding plate and the wall, increase the leak-proof effect, and has high practical value. Attached Figure Description
