The utility model belongs to the technical field of cable protection tubes, in particular to cable protection tube detection equipment, which comprises a mounting seat, a control device is arranged outside the mounting seat, and the control device comprises a control motor, a threaded rod, a movable plate, an extrusion plate and an arc plate. According to the cable protection tube detection equipment, when the cable protection tube is limited, the cable protection tube is firstly placed on the mounting seat, then a driving motor is started, two sliding plates are controlled to clamp the cable protection tube, an adjusting rod is rotated, a clamping plate is controlled to drive a mounting rod to move, and an alarm is made to be attached to the inner wall of the cable protection tube; when the rigidity of the cable protection pipe is detected, the control motor is started, the extrusion plate is controlled to extrude the pressure sensor, at the moment, the pressure sensor can test the pressure reading, and when the cable protection pipe deforms, the alarm can be extruded to give an alarm. At this time, the rigidity of the cable protection tube can be detected by observing the reading of the pressure sensor.

The application discloses a precise and simple FCM ship body forming die. The die is made of a plurality of station plates, positioning clamping plates and face plates which are connected to form a reduced-size frame with ship body lines inside. The face plates in the frame are attached with forming surfaces which are composed of a glass fiber strength layer, a polyester putty layer and a surface gel coat layer. The frame is connected and fixed with a base and a supporting rod made of rectangular tubes to form a stable ship body die. On the face plates in the frame, reference points calibrated by a laser range finder are arranged at the intersection of each station and different waterlines, and the connecting lines of the reference points form a point net which is the same as the ship body lines, so as to mark the size of the forming surface, thereby ensuring the size accuracy, smooth lines and smooth surface of the die. The die is made of light materials, has the advantages of light weight, stable structure, precise lines, simple process, short production cycle and low manufacturing cost, and is suitable for the production of FCM ship bodies with high production technical requirements and small production batches.
