Abstract
The invention discloses a hydraulic pressure sensor protective cover comprising a mounting plate. A flow blocking pipe used for preventing water inflow is fixedly mounted on the mounting plate, the flow blocking pipe is of a hollow cylinder structure, and a hydraulic pressure sensor is arranged inside the flow blocking pipe. A cable extending to the outside of the flow blocking pipe to send signals out is connected to the hydraulic pressure sensor. The top of the flow blocking pipe is equipped with a fixed base used for narrowing the upper opening of the flow blocking pipe. A rubber plug is arranged on a step structure inside the fixed base. A gasket is arranged on the rubber plug. The middle parts of the rubber plug and the gasket are each provided with a small hole for the cable to pass through. The upper part of the fixed base is threaded connection with a hole-passing bolt for axially compressing the rubber plug. The cable sequentially passes through the fixed base, the rubber plug, the gasket and the hole-passing bolt and further extends to the outside of the flow blocking pipe. The hydraulic pressure sensor protective cover is simple and reasonable in structure design and convenient to mount, and can reliably protect a hydraulic pressure sensor and isolate the hydraulic pressure sensor from the outside for long a long time.
Description
Technical field
The invention belongs to subsea equipment maintenance technology field, it is specifically related to a kind of hydraulic pressure sensor protective guard.
Background technology
Hydraulic pressure sensor is a kind of detection device, the information measured can be experienced, and the information that experience can be detected, the information being for conversion into electrical signal or other desired forms according to certain rules exports, to meet the requirements such as the transmission of information, process, storage, display, record and control. It is the primary link realizing Aulomatizeted Detect and control. The significant parameter characterizing hydraulic pressure sensor characteristic has: the linear lag, sensitivity, sluggishness, repeatability, drift etc. These parameters are affected by the external environment all very big. How to avoid the impact of external environment, it is determine that hydraulic pressure sensor measures whether accurate prerequisite.
Summary of the invention
Technical problem to be solved by this invention is for above-mentioned deficiency of the prior art, it is provided that a kind of hydraulic pressure sensor protective guard, and its structure design is simple, reasonable, convenient installs, it is possible to protection hydraulic pressure sensor reliably and with long-term is isolated from the outside.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of hydraulic pressure sensor protective guard, comprise mounting plate, it is characterized in that: described mounting plate is installed with the baffle pipe for stoping water to flow into, described baffle pipe is hollow circular cylinder structure, described baffle pipe inside is provided with hydraulic pressure sensor, described hydraulic pressure sensor is connected to the cable extending to baffle pipe outside and being spread out of by signal, the top of described baffle pipe is provided with the permanent seat for reducing baffle pipe upper opening, described permanent seat inside is ledge structure, the ledge structure of described permanent seat inside is provided with the rubber plug for blocking baffle pipe upper opening, described rubber plug is provided with pad, the centre of described rubber plug and pad is provided with for the aperture through cable, the top of described permanent seat has been threaded perforated bolt by rubber plug axial compression, described cable is successively through permanent seat, rubber plug, it is outside that pad and perforated bolt extend to baffle pipe, the tube wall of described baffle pipe is equidistantly laid with the aperture having an impact for reducing baffle pipe interior atmospheric pressure.
Above-mentioned a kind of hydraulic pressure sensor protective guard, it is characterised in that: the material of described perforated bolt, pad, permanent seat, baffle pipe and mounting plate is stainless steel.
Above-mentioned a kind of hydraulic pressure sensor protective guard, it is characterised in that: the lower end of described baffle pipe welds on a mounting board.
The present invention compared with prior art has the following advantages:
1, in the hydraulic pressure sensor protective guard of the present invention permanent seat together with the top thread connection of baffle pipe; rubber plug is put on the step at permanent seat center; pad is placed on the top of rubber plug, then, is screwed into perforated bolt at the center of permanent seat; by rubber plug axial compression; realize its radial swelling, cable is extruded, limits it and move axially; therefore, hydraulic pressure sensor is arranged on baffle pipe inside by stable reliably.
2, the structure design of the present invention is simple, reasonable, convenient installs, it is possible to protection hydraulic pressure sensor reliably and with long-term is isolated from the outside.
Below by drawings and Examples, the technical scheme of the present invention is described in further detail.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Description of reference numerals:
