Technical Field

The invention belongs to the field of measuring the compression quantity of an object under high water pressure, and particularly relates to a device for measuring the compression quantity of a submerged object under high water pressure.

Background

The pressure-bearing object has larger compression capacity under the water pressure, and the diving and floating safety of the pressure-bearing object can be ensured only by accurately measuring the pressure-bearing object in the deep sea submersible vehicle; however, the traditional measurement method cannot accurately and conveniently measure the compression amount of the entity soaking part, often ignores the compression amount or roughly estimates the compression amount by using a formula, and often has larger deviation with an actual value; at present, in a related method for measuring submerged objects under water, a measuring method for the compression deformation of a pressure-resistant cabin shell of an underwater glider is mentioned in the patent of the measuring device and the measuring method thereof, the patent number is CN 108253922A, but the method cannot measure the compression under water pressure of a non-cavity pressure-resistant body or entity.

Disclosure of Invention

In order to solve the problem that the compression amount of the submerged object under high water pressure cannot be accurately measured, the invention provides the compression amount measuring device for the submerged object under high water pressure. I.e. a simple and accurate measurement of the amount of compression.

A device for measuring the compression of a submerged object under high water pressure; the device is provided with a water tank, a water plug sealing ring, a movable sealing piston sealing ring, a marking needle and a marking disc; a water outlet with threads is arranged on the side surface of the water tank, and a water plug is screwed in the water outlet through threaded connection; the upper end of the water tank is provided with a fixing hole, one side of the fixing hole is provided with a notch, and a movable sealing piston is placed in the fixing hole and is in movable sealing fit with the water tank; the side surface of the notch is provided with a marking disc, the marking needle is fixed on the movable sealing piston through threads, can move up and down in the notch along with the movement of the movable sealing piston, and leaves a track on the marking disc; the movable sealing piston sealing ring is arranged in a groove on the movable sealing piston, and the water blocking sealing ring is arranged in a groove on the water blocking, so that the sealing effect of the water tank is ensured; after the object is compressed by the water pressure, the dynamic seal piston can correspondingly move to ensure the balance of the pressure inside and outside the water tank, and the compression amount of the pressure-bearing object under the water pressure is measured by measuring the moving displacement amount.

The invention relates to a device for measuring the compression quantity of a submerged object under high water pressure, which balances the pressure in a water cabin and the pressure outside the water cabin, so that the pressure outside the water cabin is timely and accurately transmitted into the water cabin, and the water pressure is the pressure borne by the submerged object in the water cabin; the device has simple structure, and can effectively and safely measure the deformation quantity of the object through the track of the marking needle; by utilizing the balance relation of the internal pressure and the external pressure of the water tank, the external water pressure of the water tank is converted into the pressure applied to the object, and the corresponding relation between the deformation of the object and the applied pressure can be accurately established.

Detailed Description

The invention is described in further detail below with reference to the accompanying drawings:

as shown in fig. 1 to 6, the invention comprises a dynamic seal piston 1, a water tank 2, a water plug 3, a marking needle 4, a marking disc 5, a dynamic seal piston seal ring 6, a water plug seal ring 7, a water outlet 8, a fixing hole 9 and a notch 10; and placing the object to be measured in the water tank 2, filling the water tank 2 with water, and not screwing the water plug 3 with the water tank 2 at the moment.

Step 1: screwing a marking needle 4 onto the movable sealing piston 1 through threads, wherein a marking disc 5 is always fixedly arranged on the side face of a notch 10, then installing a preselected movable sealing piston seal ring 6 into a groove of the movable sealing piston 1, assembling the preselected movable sealing piston seal ring into a fixed hole 9 of a water cabin 2 through sealing fit, enabling the interior of the water cabin 2 and the exterior of the water cabin 2 to reach a sealing state, pushing the movable sealing piston 1 to move to an initial preset position, and at the moment, the fixed marking needle 4 just contacts with the marking disc 5 and can leave a motion track, and water in the water cabin 2 starts to flow out from a water outlet 8; preliminarily fixing the dynamic sealing piston 1; assembling the selected water plug sealing ring 7 into the groove of the water plug 3 in a sealing fit manner, and then screwing the water plug 3 and a water outlet 8 on the side surface of the water cabin 2 to achieve a sealing state; finally, the initially fixed dynamic sealing piston is restored to a free state, and the water tank is safely immersed in the pressurized liquid; the compression amount of the submerged object can be preliminarily measured; under the action of the external pressure of the water tank 2, objects in the tank can be compressed, in order to ensure the balance of the internal pressure and the external pressure of the water tank 2, the dynamic seal piston 1 can move, the marking needle 4 scratches the marking disc 5 and leaves a motion track, and therefore the comprehensive compression V of the objects to be measured and water in the tank can be calculated₁。

Step 2: taking the water cabin 2 out of the liquid with the pressure being relieved, taking the movable sealing piston 1 out of the fixing port 9 of the water cabin 2, taking out the object to be measured, adjusting the water cabin 2 to a proper position to prevent the water in the water cabin 2 from leaking out, and ensuring that the volume of the water is not changed; as shown in FIG. 7, by repeating step 1, the compression V of the water in the chamber under the same pressure can be calculated₀. The compression V = V of the measured object is known₁-V₀. At this time, the compression V of the submerged object is calculated.
