Description
Technical field
The present invention relates to a kind of non-maintaining underwater Magnetic Sensors.
Background technique
With the needs of human social development and the progress of science and technology, the scale of Underwater Engineering is increasing, under water
The fields such as investigation, offshore oil detection, lifesaving of speedily carrying out rescue work, underwater civil engineering construction and the ocean military affairs of resource largely use not
Same type, the underwater instrument equipment of different function.Therefore, the design of underwater instrument equipment and development are universal and important works
Make.
It in underwater instrument equipment, many times needs to transmit information by induction magnetic signal, how sensing
Electromagnetic signal passes and long-term work normally under water is field a great problem urgently to be resolved.
Existing watertight Magnetic Sensor is mainly irrigated in sensor shell body, since silicone oil is with good thermally conductive
Property, insulating properties and be widely used.But since the density ratio water of silicone oil is small, when the shell breakage of sensor external, seawater pole
Easily silicone oil is squeezed out hence into enclosure interior, the entrance of seawater can generate corrosion and damage to sensor and signal cable.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of watertightnesses well, prevents seawater corrosion, non-maintaining water
Lower Magnetic Sensor.
The technical scheme to solve the above technical problems is that a kind of non-maintaining underwater Magnetic Sensor, including shell
In the intracorporal Magnetic Sensor of the shell, the shell includes the cylindrical lower case of upper end opening and is fastened on described for body and setting
Top cover in lower case, the cable hole passed through for signal cable is provided on the top cover, and described signal cable one end and magnetic sense
Device connection, the other end extend to the water surface or more and connect with control equipment, silicone grease are perfused in the lower case, the silicone grease did not had
Magnetic Sensor and there are secure chambers between the top cover；Density of sea water is less than the density of the silicone grease, the density of the silicone grease
For 1.2g/cm3, the height of the secure chamber is 10mm.
The beneficial effects of the present invention are: silicone grease is perfused in lower case, silicone grease has good waterproof seal, waterproof, resists
Solvent borne and creep resistance energy do not corrode metal and more sticky.Because the density of seawater is about 1.028g/cm3, work as lower case
When damaged, since density of sea water is less than the density of silicone grease, seawater can float upwards, without by silicone grease extrusion cavity, under
The seawater of shell can float to the position of secure chamber upwards, would not destroy Magnetic Sensor and signal cable.Top cover and lower case
Fastening structure, the work such as the installation of magnetic strength device, the perfusion of silicone grease, the connection of cable and maintenance can be made more convenient；Make
Silicone grease is squeezed out after shell can be entered with the biggish silicone grease of density to avoid seawater, the height of secure chamber is reserved not in lower case top
Can be excessively high, be not otherwise able to satisfy the requirement for covering Magnetic Sensor, can not be too low, otherwise into the seawater of shell slightly it is more then not
Silicone grease can be squeezed out from top to bottom, it is possible to corrosion sensor or cable.
Based on the above technical solution, the present invention can also be improved as follows.
Further, the top cover is connect by bolt with lower case.
Beneficial effect using above-mentioned further scheme is that top cover is connect by bolt with lower case, such connection side
Formula can not only place seawater and enter in shell, but also installation Magnetic Sensor, perfusion silicone grease and the connection cables that can be convenient.
Further, being equipped at the cable hole prevents water from entering the intracorporal watertight head of shell.
Beneficial effect using above-mentioned further scheme is that watertight head can prevent gap of the water between cable and top cover
Into in shell.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention.
In attached drawing, parts list represented by the reference numerals are as follows:
1, shell, 11, lower case, 12, top cover, 2, signal cable, 3, cable hole, 4, Magnetic Sensor, 5, secure chamber, 6, spiral shell
Bolt, 7, watertight head.
Specific embodiment
The principle and features of the present invention will be described below with reference to the accompanying drawings, and the given examples are served only to explain the present invention, and
It is non-to be used to limit the scope of the invention.
As shown in Figure 1, a kind of non-maintaining underwater Magnetic Sensor, passes including shell 1 and the magnetic being arranged in the shell 1
The top cover 12 that sensor 4 the cylindrical lower case 11 including upper end opening at the shell 1 and is fastened in the lower case 11, institute
The cable hole 3 for being provided on top cover 12 and passing through for signal cable 2 is stated, described 2 one end of signal cable is connect with Magnetic Sensor 4, another
End extends to the water surface or more and connect with control equipment, silicone grease is perfused in the lower case 11, the silicone grease did not had Magnetic Sensor 4
And there are secure chambers 5 between the top cover 12.
The density of the silicone grease is 1.2g/cm3。
The top cover is connect by bolt 6 with lower case 11.
The height of the secure chamber 5 is 10mm.
The watertight head 7 for preventing water from entering in shell 1 is equipped at the cable hole 3.
