Telescopic cooling liquid conveying device

Abstract

The invention belongs to the technical field of flexible dynamic sealing, and provides a telescopic cooling liquid conveying device which comprises a shell and an inner cylinder, the shell comprises a shell insertion end and a shell fixing end, the inner cylinder comprises an inner cylinder insertion end and an inner cylinder fixing end, a through hole formed in the inner cylinder is communicated with the inner side of the shell, a pressure relief opening is formed in the shell, and a pressure relief valve is arranged in the pressure relief opening. A sealing combination is arranged on the inner side of the outer shell inserting end of the outer shell and tightly clamped on the outer side of the inner barrel, a guide sleeve for holes is arranged on the outer side of the inner barrel inserting end of the inner barrel, and a guide sleeve for shafts is arranged on the inner side of the outer shell inserting end of the outer shell. The device overcomes the contradiction between high power and high maneuverability of the radar array plane, can ensure that the normal transmission of large-drift-diameter high-flow cooling liquid is always kept in the working and withdrawing processes of the radar array plane, can meet the transmission of media such as water, hydraulic oil, corrosive fluid and gas, has a wide application prospect, and is suitable for popularization and application. The problem of transmission of telescopic fluid media in a severe environment is solved.

Description

technical field [0001] The invention mainly relates to the technical field of flexible dynamic sealing, in particular to a telescopic cooling liquid transmission device. Background technique [0002] Modern radars pursue longer detection distances, higher positioning accuracy, and stronger mobility. Therefore, radar design needs to take into account high power, volume and weight. The increase of the front can quickly increase the power of the radar, but the problem is that the maneuverability and transportation of the radar become worse. In order to solve this pair of contradictions, a front lifting mechanism is introduced in the radar design. However, in the process of raising and lowering the front, how to ensure that the coolant can always be transmitted normally is a difficult problem. In the past, rubber hoses or metal hoses were generally used for the connection of cooling pipes in this limited range of motion, but this method has obvious disadvantages: the hose has...

Problems solved by technology

[0003] In order to solve the problem of connecting cooling pipelines during the raising and lowering of the existing radar front, the present invention provides a telescopic cooling liquid transmission device, which overcomes the contradiction between the high power and high mobility of the radar front, and can ensure the smoothness of the radar front. During the work and withdrawal process, the normal transmission of large diameter and high flow coolant is always maintained
