Technical Field

[0001] This utility model relates to the field of industrial testing equipment technology, and in particular to a protective housing for a desktop industrial CT scanner. Background Technology

[0002] Industrial CT equipment generates high-energy X-rays or gamma rays during the inspection process, and radiation must be shielded by a protective housing to ensure operational safety.

[0003] In the prior art, a search revealed a Chinese patent disclosure entitled "A Protective Housing for a Desktop Industrial CT Scanner," application number "201921317889.0." This patent mainly includes a table and a housing. The housing is connected to the table via legs. A motor is mounted on the upper left side of the table, and a counterweight is located on the upper right side. The motor's output shaft is connected to the high-speed shaft of a reducer, and the reducer's low-speed shaft is connected to a drive wheel. The drive wheel is connected to a driven wheel, and screws A and B are respectively connected to the upper ends of the drive wheel and the driven wheel. Rod B has a groove in the middle of the front end of the housing. Sealing strips are connected to the inner walls of both sides of the groove. Nuts A and B are screwed onto the outer sides of screws A and B respectively. A door is connected to the front end of nuts A and B. Protrusions are provided at both the top and bottom of the door. A column is connected to the middle of the upper end of the housing. A limit plate is connected to the upper part of the front end of the column. A slot A is provided at the lower end of the limit plate. A slot B is provided on the lower inner wall of the groove. While the above patent has advantages such as small size, strong radiation protection, good shock absorption, strong stability, and high safety, the method of enclosing the CT equipment with a housing for shielding provides only a single shielding effect; furthermore, the insufficient ventilation design of the housing affects the heat dissipation of the CT equipment. Therefore, this utility model provides a protective housing for a desktop industrial CT scanner to solve the problems mentioned in the background art. Utility Model Content

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0027] Reference Figure 1-6This utility model provides a protective housing for a desktop industrial CT scanner, comprising an upper housing 1, a lower housing 2 located at the bottom of the upper housing 1, and a top cover 16 located at the top of the upper housing 1. The upper housing 1 has multiple through slots 7 on its rear side, and a heat dissipation assembly is provided on one side of each through slot 7. The heat dissipation assembly includes a heat dissipation plate 4 fixed to the upper housing 1, multiple heat dissipation channels 8 located inside the heat dissipation plate 4, a mounting frame 5 fixed to the heat dissipation plate 4, and a fan 6 fixed to the mounting frame 5. The heat dissipation channels 8 are configured with a multi-bend structure and communicate with the through slots 7 to achieve air circulation, and the inner wall of the heat dissipation channels 8 is provided with a lead layer.

[0028] The through slot 7 on the upper housing 1 communicates with the multi-bend heat dissipation channel 8 inside the heat sink 4. The installed fan 6 is used for forced convection heat dissipation to achieve heat dissipation inside the housing. The inner wall of the heat dissipation channel 8 is lead-plated and adopts a multi-bend structure to form a radiation attenuation path. The multiple turns help to reduce the radiation dose. While ensuring radiation safety, it optimizes heat dissipation performance and has strong practicality.

[0029] A shielding assembly is provided on the side of the heat sink 4 near the mounting frame 5. The shielding assembly is used to control the opening and closing of the heat dissipation channel 8. The shielding assembly includes an L-shaped mounting bracket 9 symmetrically fixed on the heat sink 4, a cylinder 10 fixed on the mounting bracket 9, a connecting plate 11 fixed on the piston rod of the cylinder 10, and a baffle 12 fixed between the connecting plates 11. The baffle 12 can be inserted into the heat dissipation channel 8, and the side of the baffle 12 near the heat dissipation channel 8 is designed with a conical structure to facilitate the guiding flow of gas. A temperature sensor 17 is fixed on the inner wall of the lower housing 2 to monitor the temperature inside the housing in real time.

[0030] A cylinder 10 drives the baffle 12. When the temperature sensor 17 detects that the internal temperature is too high, the cylinder 10 moves the baffle 12 away from the heat dissipation channel 8, opening the heat dissipation channel 8 to facilitate heat dissipation. When heat dissipation is not needed, the cylinder 10 drives the baffle 12 to retract and insert into the heat dissipation channel 8, closing the heat dissipation channel 8 and ensuring radiation safety.

[0031] Both the upper shell 1 and the lower shell 2 are made of aluminum alloy, combining lightweight design with structural support. An inner shell 3 is fixed to the inner wall of both the upper shell 1 and the lower shell 2. The inner shell 3 is made of multiple layers of lead plates 31 and boron-containing polyethylene sheets 32, arranged alternately to form an alternating, superimposed shielding structure that effectively shields against X-rays and neutron radiation. An absorption layer made of silicon carbide is coated on the inner walls of both the inner shell 3 and the mounting frame 5 to reduce internal scattering.

[0032] The bottom of the upper housing 1 is provided with a plug-in part 14, and the bottom of the lower housing 2 is provided with a plug-in plate 15. The plug-in plate 15 and the plug-in part 14 are plugged in together. Multiple screws 13 are evenly fixed on the top of the upper housing 1. The lower housing 2 and the top cover 16 are both inserted through the screws 13, and the screws 13 are threaded with nuts located on the top of the top cover 16.

[0033] The upper housing 1, lower housing 2 and top cover 16 are fixed by the plug-in part 14, plug-in plate 15 and screw 13, which makes it easy to disassemble and assemble, and facilitates the disassembly of the top cover 16 and the upper housing 1 for the maintenance of the industrial CT inside the housing.

[0034] Both the upper housing 1 and the lower housing 2 are equipped with observation windows 18 on their front sides. The observation windows 18 are made of multi-layered lead glass, which allows operators to observe the testing process in real time while ensuring the protective effect.

[0035] Working principle: When the temperature sensor 17 detects that the internal temperature is too high, the cylinder 10 drives the baffle 12 to move away from the heat dissipation channel 8, thereby opening the heat dissipation channel 8 and facilitating heat dissipation.

[0036] The through slot 7 on the upper housing 1 communicates with the multi-bend heat dissipation channel 8 inside the heat sink 4. The installed fan 6 is used for forced convection heat dissipation to achieve heat dissipation inside the housing. In addition, the inner wall of the heat dissipation channel 8 is lead-plated and adopts a multi-bend structure to form a radiation attenuation path. The multiple turns help to reduce the radiation dose, thus optimizing heat dissipation performance while ensuring radiation safety.

[0037] When cooling is not required, cylinder 10 drives baffle 12 to retract and insert into the cooling channel 8, and baffle 12 closes the cooling channel 8 to ensure radiation safety.
