Description

TECHNICAL FIELD

[0001] The utility model relates to fluid metering equipment, concretely relates to the recovery of electronic device module of fluid metering device. BACKGROUND

[0002] The underwater multiphase flowmeter is an important flow measurement device for offshore oil engineering, and researchers have proposed many device schemes for the underwater multiphase flowmeter in the early stage. These flowmeters all need to transmit parameters such as temperature, pressure, and gamma count collected underwater to the water platform. The early flowmeters highly integrate various measurement modules and are installed on the underwater manifold, so they are almost impossible to disassemble and recover.

[0003] Later, a set of recoverable electronic bin scheme (Chinese patent: publication number CN112629608A) was proposed according to the demand, which realizes the recovery of the electronic bin module. This recovery scheme still has some deficiencies in the underwater installation process, the most notable of which is that no special locking mechanism is arranged between the recoverable electronic bin part and the temporarily placed cylinder, and under the action of long-time water flow impact and vibration, the electronic bin part will be loose, pulling the pipeline between it and the flowmeter, and there is a risk of electronic bin loosening and water filling. In addition, there are other problems such as insufficient buffering when installing the electronic bin, and the electronic bin is too large to be processed. UTILITY MODEL CONTENTS

[0004] The utility model first needs to solve the technical problem that no special locking mechanism is arranged between the recoverable electronic bin part and the temporarily placed cylinder, and there is a risk of loosening. The main technical scheme adopted to solve this problem is:

[0005] A recoverable electronic bin, comprising a cylinder and an electronic bin body, a signal input plug, a signal output plug, and an ROV handle are arranged on the electronic bin body, and an electrical device is arranged inside the electronic bin body;

[0006] One end of the cylinder is closed, and the other end is open;

[0007] The electronic bin body is inserted from the open end of the cylinder, and the key is:

[0008] The electronic bin body and the cylinder are rotationally locked;

[0009] The closed end of the cylinder is provided with an elastic buffer, and the elastic buffer is compressed after the electronic bin body is inserted into the cylinder;

[0010] The elastic buffer acts on the electronic bin body, so that the electronic bin body has a tendency to move away from the elastic buffer, and the electronic bin body remains in a rotationally locked state under the tendency to move away.

[0011] The rotation locking scheme added in the scheme can keep the electronic cabin body and the cabin cylinder in stable connection, thereby avoiding the electronic cabin body from loosening. The cabin cylinder is fixed on other designated equipment on the seabed. BRIEF DESCRIPTION OF DRAWINGS
