Description

Technical Field

[0002] After market research, the best temperature-resistant endoscope is the Welin Evita industrial endoscope R8-14-90-56 (as shown below). The viewing angle of this endoscope is 56°, the working part temperature resistance is -40℃ to 121℃, the working probe length is 14cm, and it is equipped with a 32mm camera interface. This model of endoscope was chosen mainly because its working part can withstand a maximum temperature of 120℃, and the focal length and magnification can be freely adjusted to meet different test requirements.

[0003] However, this endoscope also has some indicators that cannot meet the test requirements of this project. There are two main points: ① The working probe part is 8mm thick and is placed in the aircraft engine. Due to long-term vibration and other problems, the rigidity of this position is insufficient and it is easy to cause rapid damage. Its structural strength should be further strengthened; ② The project requires that the endoscope can withstand an ambient temperature of not less than 300°C, while the maximum temperature resistance of this endoscope is 120°C, and further cooling and heat dissipation are required to meet the needs of this project.

[0004] The working part of the existing Welinyiweite industrial endoscope, which is similar to the present invention, has a maximum temperature resistance of 120°C, and the focal length and magnification can be freely adjusted to meet different test requirements. However, the industrial endoscope has the disadvantages of low ambient temperature resistance, which cannot meet the high temperature resistance requirement of 300°C required by the project, and low probe rigidity, which is easy to cause rapid damage.

[0005] In order to solve the above problems, the present invention provides an endoscope cooling bracket suitable for use in high temperature environments, which solves the problem that existing endoscopes cannot work normally and continuously in an environment of 400-500°C. Summary of the invention

[0006] In order to solve the above problems, the present invention provides an endoscope cooling bracket suitable for use in high temperature environments, which uses high-pressure cooling gas to insulate the probe and reduce the operating temperature of the endoscope probe to ensure that it can work normally and continuously at a temperature exceeding its own operating temperature.

[0007] To achieve the above object, the present invention provides the following solutions:

[0010] Preferably, a first sealing ring is provided at one end of the expansion section close to the cooling sleeve, and two surfaces of the first sealing ring are in contact with the inner wall of the endoscope reinforcing fixing sleeve and the outer wall of the endoscope objective tube respectively.

[0011] Preferably, a connecting plate is provided at one end of the cooling sleeve connected to the casing, a mounting through hole is opened on the connecting plate, the mounting through hole matches the fixing hole of the casing and is fixed by bolts penetrating the mounting through hole and the fixing hole.

[0016] Compared with the prior art, the present invention has achieved the following technical effects:

[0017] The present invention wraps and cools the endoscope working probe by introducing high-pressure cooling gas into the ventilation sleeve and into the high-speed heat exchange channel and the exhaust channel, performs heat exchange through a large amount of high-pressure cooling gas, and simultaneously utilizes the high-pressure cooling gas to insulate the probe, thereby reducing the working temperature of the endoscope probe, so as to ensure that it can work normally and continuously at a temperature exceeding its own working temperature.
