Embodiment Construction

[0011] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0012] Such as Figure 1 to Figure 6 As shown, the present invention includes a dynamic sealing piston 1, a water tank 2, a water plug 3, a marking needle 4, a marking plate 5, a dynamic sealing piston sealing ring 6, a water blocking sealing ring 7, a water outlet 8, a fixing hole 9, and a notch 10. Place the object to be measured in the water tank 2, and the water tank 2 is filled with water. At this time, the water plug 3 is not tightened with the water tank 2.

[0013] Step 1: Tighten the marking pin 4 onto the dynamic sealing piston 1 through threads, the marking plate 5 is always fixedly installed on the side of the notch 10, and then install the pre-selected dynamic sealing piston sealing ring 6 into the groove of the dynamic sealing piston 1, Assembled into the fixing hole 9 of the water tank 2 through sealing fit, so that the inside of the water tank 2 and t...

Abstract

A device for measuring the compression amount of an immersed object under high water pressure is provided with a water tank, a water plug, a water plug sealing ring, a dynamic sealing piston, a dynamic sealing piston sealing ring, a marking needle and a marking disc. A threaded water outlet is formed in the side surface of the water tank, and the water plug is screwed in the water outlet through threaded connection; a fixing hole is formed in the upper end of the water tank, a notch is formed in one side of the fixing hole, and the dynamic sealing piston is placed in the fixing hole and is indynamic seal fit with the water tank; the marking disc is installed on the side face of the notch, the marking needle is fixed to the dynamic sealing piston through threads and can move up and down inthe notch along with movement of the dynamic sealing piston, and a track is left on the marking disc; and the dynamic sealing piston sealing ring is arranged in a groove in the dynamic sealing piston, the water plug sealing ring is arranged in a groove in the water plug, and the sealing effect of the water tank is guaranteed through the dynamic sealing piston sealing ring and the water plug sealing ring. The internal and external pressures of the device are transmitted, so that the internal and external pressures are equal, and the compression amount of an object is converted into the displacement amount of the dynamic sealing piston. Therefore, the compression amount can be simply and accurately measured.

Description

technical field [0001] The invention belongs to the field of measuring the compression amount of an object subjected to high water pressure, and more specifically relates to a device for measuring the compression amount of a water-immersed object under high water pressure. Background technique [0002] The pressure-bearing object has a large amount of compression under water pressure, and accurate measurement must be carried out in the deep-sea submersible to ensure the safety of its submersion and surfacing; but the traditional measurement method cannot accurately and conveniently measure the compression amount of the submerged part of the entity The measurement is often ignored or roughly estimated by the formula, which often deviates greatly from the actual value; at present, among the methods related to the measurement of water-immersed objects under water pressure, "Measuring Device for Compressive Deformation of Underwater Glider Pressure Chamber Shell and its measurem...
