Problems solved by technology
When the fuel rod is damaged, the upper pipe seat needs to be removed for replacement. At this time, the upper pipe seat can only be removed by destroying the skirt of the sleeve screw. Potential Safety Risks of Drain Pools
When replacing the sleeve screw, there are great difficulties in the operation of taking, placing, and transporting underwater, and it is even more difficult to use the sleeve screw to connect the upper tube base and the guide tube again.

Embodiment Construction
[0030] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.
[0031] Such as figure 1 , 2 As shown, the quick detachable connection device between the guide tube and the upper tube base according to an embodiment of the present invention includes a sleeve assembly; the upper tube base 1 is provided with a mounting hole 10, and the sleeve assembly is installed on the guide tube and connected with the mounting hole 10 match. The socket assembly is installed on the guide pipe to form an integral structure with it, and no falling parts will be produced, which eliminates potential safety hazards; the connection between the guide pipe and the upper pipe seat 1 is realized by using the socket assembly and the mounting hole 10 to lock together.
[0032] Wherein, the sleeve assembly incl...

The invention discloses a guide tube and upper tube base rapidly detachable connection device and method. The rapidly detachable connection device comprises a sleeve joint assembly that is mounted onthe guide tube and fits a mounting hole on the upper tube base. The sleeve joint assembly includes a casing tube sheathed to the guide tube, a connection tube disposed at one end of the casing tube far from the guide tube, an axially movable locating ring that is sleeved on the connection tube and can rotate, and an anti-rotation piece arranged on the locating ring. The mounting hole is internallyequipped with a step that abuts against the locating ring and limits the sleeve joint assembly to break away from the mounting hole. The connection tube is equipped with a first clamping slot and a second clamping slot for the anti-rotation piece to detachably fit. The device provided by the invention has the characteristics of simple structure and reliable connection, solves the problem that theconnection of the upper tube base and the guide tube cannot be disassembled and assembled repeatedly, and can achieve repeated disassembly and assembly and safe self-locking.
Description
technical field [0001] The invention relates to the technical field of nuclear fuel assemblies, in particular to a quick and detachable connection device and method for a guide pipe and an upper pipe seat. Background technique [0002] Nuclear fuel assemblies are generally composed of upper nozzles, lower nozzles, guide tubes, instrumentation tubes, grids and fuel rods, among which the lower nozzles, guide tubes, instrumentation tubes and grids form the skeleton of the fuel assembly. The guide tube connection serves to protect the fuel rods. [0003] At present, the connection method between the upper tube seat and the guide tube in the fuel assembly is mainly the threaded connection between the sleeve screw and the sleeve tube, and the skirt of the sleeve screw expands into the groove of the guide tube hole of the upper tube base, and then the upper tube base and the guide tube Connect to become one. When the fuel rod is damaged, the upper pipe seat needs to be removed fo...
