[0022] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following embodiments are used to illustrate the technical solution of the present invention, but are not intended to limit the scope of protection of the present invention.

[0023] Example:

[0024] like Figures 1 to 5 As shown, the utility model provides a CT scanning frame with a protective structure, including a support base 1, two groups of protective shells 2 are arranged above the support base 1, and a limiting groove 12 is provided on the top of the support base 1. The two groups of protective shells 2 are both clamped in the limiting groove 12. The setting of the support base 1 provides a stable basic support for the entire CT scanning frame, effectively ensuring that the equipment will not shake or displace during the scanning process, thereby ensuring the accuracy and safety of the scanning. The opening of the limiting groove 12 facilitates the installation and positioning of the protective shell 2, ensuring that the protective shell 2 can be accurately clamped into the specified position, improving the efficiency and accuracy of assembly, and the protective shell 2 effectively protects the internal scanning components, reduces interference and damage to the scanning equipment by external factors, and can block a part of the radiation leakage from the scanning process, thereby providing additional protection for the operator and the surrounding environment.

[0025] Observation windows 3 are provided on adjacent surfaces of the two sets of protective shells 2. The two sets of observation windows 3 are made of barium-containing glass material. The barium element has a strong ability to absorb and scatter radiation, and can effectively block radiation such as X-rays and gamma rays, providing reliable protection for users. While achieving effective radiation protection, the observation windows 3 can maintain good transparency and clarity, so that the observation effect is relatively clear, and does not affect normal observation and operation through the observation windows 3. In addition, the material is not easily corroded by chemical substances, has good mechanical strength and wear resistance, and can effectively maintain its stable performance and appearance in a more complex environment, so that it can withstand long-term use and frequent cleaning without being easily damaged or experiencing performance degradation.

[0026] A sealing ring 8 is provided between the two groups of observation windows 3. The sealing ring 8 is made of a barium-containing rubber material with excellent elasticity. It can fit tightly to the contact surface through adhesive bonding to form an effective seal, thereby preventing dust, water vapor and other impurities from entering the scanning frame, while ensuring that radiation does not leak from the connection. It also has good compression and tensile strength and chemical corrosion resistance, can withstand the pressure and vibration of the connection, and is not easily deformed or damaged, thereby ensuring a long-term and stable sealing effect, and can work stably for a long time in a complex chemical environment, extending the service life of the sealing ring 8.

[0027] The two ends of the sealing ring 8 are respectively connected to the two groups of observation windows 3. A sensor alarm 9 is provided on the inner side of the sealing ring 8. The sensor alarm 9 adopts the Belit FS311 radiation monitor, which monitors the radiation level outside the scanning frame in real time. Once the radiation exceeds the safety threshold, the sensor alarm 9 can promptly issue an alarm to remind the operator to take corresponding measures, providing an active monitoring and early warning mechanism for radiation protection, thereby effectively enhancing the safety of the entire scanning process.

[0028] Two sets of lead layers 4 are provided between the two sets of protective shells 2. The two sets of lead layers 4 are respectively embedded in the two sets of protective shells 2. The lead material has excellent radiation shielding capabilities. The two sets of lead layers 4 can effectively block the X-ray radiation generated during the CT scanning process, reducing the leakage of radiation to the external environment, thereby ensuring the safety of surrounding personnel. The two sets of lead layers 4 are embedded in the protective shells 2, which increases the stability and reliability of the protection. They are not easily displaced or deformed by external forces or long-term use. Shielding covers 5 are provided on the adjacent surfaces of the two sets of lead layers 4. The shielding covers 5 are made of ferrite material, which enables them to efficiently absorb electromagnetic waves, thereby reducing electromagnetic noise, optimizing the electromagnetic environment of the scanning equipment, and improving image quality. In terms of radiation shielding, they can effectively attenuate radiation energy, reduce the penetration of radiation, and further enhance the protection effect.

[0029] The two sets of protective shells 2, the two sets of lead layers 4 and the two sets of shielding covers 5 are all sealed and connected by lead-containing polytetrafluoroethylene material. The lead-containing polytetrafluoroethylene material has excellent sealing properties and can effectively fill the tiny gaps between the two sets of protective shells 2, the two sets of lead layers 4 and the two sets of shielding covers 5, further reducing the possibility of radiation and electromagnetic waves leaking from the connections, thereby ensuring the safety of the surrounding environment and personnel. In addition, within the temperature variation range that may occur when the CT scanning frame is working, the lead-containing polytetrafluoroethylene material can maintain good performance and will not deform or fail due to temperature fluctuations. Its flexibility and workability enable it to adapt to connection parts of different shapes and sizes, making it easy to install and having a good sealing effect.

[0030] A plurality of condensing tubes 6 are provided at the adjacent ends of the two groups of lead layers 4. The provision of the condensing tubes 6 can effectively remove the heat generated by the CT scanning frame during operation and keep the equipment operating within a suitable temperature range, thereby helping to improve the stability and reliability of the equipment and extend its service life. A plurality of connecting blocks 7 are sleeved on the plurality of condensing tubes 6. The plurality of connecting blocks 7 are clamped on the inner side surfaces of the two groups of lead layers 4. The plurality of connecting blocks 7 firmly fix the plurality of condensing tubes 6 on the inner side surfaces of the lead layers 4, thereby preventing the condensing tubes 6 from being displaced or loosened during operation, thereby ensuring the stability of the cooling effect. A plurality of connecting holes 10 are provided at one end of the two groups of protective shells 2 and the two groups of lead layers 4, and a water outlet 11 is provided at the corresponding end of the two groups of protective shells 2. One end of multiple condenser tubes 6 passes through multiple connecting holes 10 and is connected to two groups of water outlets 11 respectively. One end of the two groups of water outlets 11 is respectively clamped on the support base 1. This structure provides smooth water inlet and outlet channels for multiple condenser tubes 6, ensuring the circulation of cooling medium, thereby achieving continuous and effective cooling, and effectively increasing the stability of the connection, so that the liquid with radiation in the pipeline can be guided and processed separately, reducing the risk of possible leakage.

[0031] The specific usage and function of this embodiment are as follows:

[0032] When using this new CT scanner, users can direct condensate into the multiple condensation tubes 6 through the water inlet 11. The heat generated by the CT scanner during operation is effectively removed through the condensate by the multiple water inlets 11, thereby preventing the CT scanner from experiencing performance degradation, lags, or malfunctions due to overheating, ensuring stable operation of the device. A stable and appropriate temperature helps maintain the accuracy and sensitivity of the scanning components, resulting in clearer and more accurate scanned images and improved medical efficiency. Simultaneously, users can observe the scanned object through the observation window 3 made of barium-containing glass. Through this observation window 3, users can clearly observe the scanned object while enjoying good radiation protection, providing timely comfort and guidance to ensure a smooth scan. The user can have a good grasp of the radiation level outside the scanning frame through the sensor alarm 9 on the sealing ring 8, and understand the radiation level outside the scanning frame in real time. Once the radiation level exceeds the safe range, the sensor alarm 9 can issue an alarm in time, and the user can quickly take corresponding protective or shutdown measures to avoid further expansion of radiation damage, making the user more at ease and reducing concerns and uncertainties about radiation safety, so that the user can perform scanning operations more attentively.

[0033] The basic principles, main features and advantages of the present invention are shown and described above. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments.
