In order to shield the magnetic attraction part 6 from the magnetic field inside the infrared thermal imaging instrument, in one embodiment, the magnetic attraction part 6 is disposed on the rear case 2, and in one example, the magnetic attraction part 6 may be disposed on the outer side of the rear case 2; a magnetic isolation member is arranged between the magnetic part 6 and the back shell 2.
In another embodiment, a metal back plate 7 is connected to the outer side of the rear housing 2, and a magnetic member 6 is disposed on the metal back plate 7, in one example, the magnetic member 6 may be disposed on the outer side of the metal back plate 7, and a magnetic isolation member is disposed between the magnetic member 6 and the metal back plate 7.
In the above two embodiments, the magnetic attraction component 6 may be a magnet, such as a neodymium-iron-boron magnet, and the magnetic separation component may be a soft magnetic material, such as SUS430 stainless steel, low carbon steel, electrical pure iron, etc. Referring to fig. 3, the magnetic shielding member may be a sheet-shaped magnetic shielding member 8a having a sheet shape, and specifically, the sheet-shaped magnetic shielding member 8a is a sheet having a small thickness and an identical shape to the shape of the rear case 2.
In an example, the thermal infrared imager provided by this embodiment is used for temperature measurement in an electric cabinet environment, and compared with installing the thermal infrared imager at a target position through screws, for example, through screws, the thermal infrared imager is installed on a thermal infrared imager support fixed in the electric cabinet in advance through screws, and the thermal infrared imager is installed at the target position through the magnetic attraction component 6, which is more convenient to assemble and disassemble. However, the magnetic field generated by the magnetic part 6 may affect the normal operation of the internal parts of the infrared thermal imager, especially the thermal imaging blocking piece, so that a magnetic isolation member may be disposed between the magnetic part 6 and the rear case 2, or a magnetic isolation member may be disposed between the magnetic part 6 and the metal back plate 7 to shield the magnetic field of the magnetic part 6 facing the internal parts of the infrared thermal imager and protect the electromagnetic sensitive elements in the internal parts of the infrared thermal imager from the magnetic field of the magnetic part.

The magnetic field is similar to the electric field, the magnetic flux is similar to the electric current, and the magnetic flux always tends to be closed along a path with the minimum magnetic resistance, namely the principle of minimum magnetic resistance, so that the magnetic isolation piece can enable the magnetic induction line to be conducted along the inside of the magnetic isolation piece, the magnetic field is blocked from being conducted towards the lower part of the bottom plate of the magnetic isolation piece, the magnetic field intensity in the direction of the bottom plate is reduced, namely the magnetic field intensity towards the inside of the rear shell is reduced, the electromagnetic sensitive element in the infrared thermal imager is protected from being influenced by the magnetic field of the magnetic absorption part 6, and the measuring precision of the infrared thermal imager is ensured.
In another example, the infrared thermal imager includes a thermal imaging module, the thermal imaging module includes a plurality of small-sized detecting units, under the radiation of the external uniform thermal field, the response outputs of the plurality of small-sized detecting units have differences, that is, the same temperature-equalizing object is measured, and the temperature values displayed by the small-sized detecting units are different. Therefore, the blocking piece and the electromagnet are arranged in the infrared thermal imager, the electromagnet can drive the shifting piece on the blocking piece to rotate, and the blocking piece is driven to rotate so as to shield each small-sized detection unit of the thermal imaging module. The baffle can form an infrared plane with uniform temperature, so that when each small detection unit of the thermal imaging module is shielded by the baffle, the baffle receives uniform infrared radiation signals, and a uniform temperature response relation can be established among the small detection units through a correction algorithm. It can be understood that the magnetic field that other magnets produced can produce the magnetic field of the electro-magnet of drive separation blade and disturb to lead to the unable normal rotation of separation blade, and then can lead to unable in order to establish unified temperature response relation through being shielded by the separation blade between each small-size detecting element of thermal imaging module, make infrared thermal imager's measuring result inaccurate. Through setting up magnetism separation piece, can shield magnetism and inhale 6 inside magnetic fields towards infrared thermal imager of part, prevent that magnetism from inhaling the rotation that the magnetic field of part 6 disturbed the separation blade to ensure infrared thermal imager's measurement accuracy.
In order to enhance the capability of shielding the magnetic attraction component 6 of the magnetic isolation component towards the magnetic field inside the infrared thermal imager, in an embodiment, the magnetic isolation component includes a bottom plate and a side wall, and the side wall is located on one side of the bottom plate and encloses a cavity with a closed end and an open end together with the bottom plate. Referring to fig. 4, in one example, the magnetic isolation member is a bowl-shaped magnetic isolation member 8b or a bowl-like magnetic isolation member.
The magnetism isolating piece can be of an integral structure, for example, the magnetism isolating piece is generated through sheet metal stamping, so that the production cost of the magnetism isolating piece can be reduced, and the production cost of the infrared thermal imager is reduced.
The magnetic part 6 of the magnetic isolation part is at least partially arranged in the cavity. The magnetic attraction component can be at least partially arranged in the cavity of the magnetic isolation component through dispensing.
Preferably, the magnetic part 6 can be integrally located in the cavity of the magnetic isolation member, and one side of the magnetic part 6 close to the opening of the cavity can be flush with the opening of the cavity to enhance the shielding effect of the magnetic isolation member. The magnetic part 6 and the magnetic isolation part can be adhered and fixed into a whole through dispensing.
As described above, the magnetic induction line of the magnetic part 6 will be conducted along the inside of the magnetic isolation member, and since the magnetic isolation member includes the side wall in this embodiment, the magnetic induction line of the magnetic part 6 will penetrate out from the opening end of the cavity or the port (also referred to as the bowl port) of the magnetic isolation member, so that the magnetic flux density in the direction of the bowl port is increased, the magnetic field is enhanced, that is, the magnetic isolation member has a magnetic gathering effect at the port. For example, the N pole of the magnetic attraction component 6 faces the bottom plate direction of the magnetic isolation component, and the emitted magnetic flux is constant. The magnetic induction line emitted from the N pole is influenced by the magnetism isolating piece to deflect, is conducted along the inside of the magnetism isolating piece and does not conduct to the lower part of the bottom plate any more, and is conducted along the inside of the magnetism isolating piece, penetrates out from the bowl mouth direction and returns to the S pole.
The magnetic induction intensity of the magnetic field generated by the magnetic part 6 is in direct proportion to the density of the magnetic induction lines, and the magnetic separation part of the structure has a magnetic concentration effect at the port. Like this, can increase magnetism and inhale the magnetic induction intensity of part 6 at the port department that separates the magnetism piece, increase magnetism and inhale the magnetic attraction of part 6.
In order to enhance the stability of the infrared thermal imaging camera in the mounting position, in an embodiment, the first end of the magnetic-shielding member 6 is flush with the port of the cavity.
Like this, when infrared thermal imager adsorbed when the mounted position department, the first end of part 6 and the port of the cavity that separates the magnetism piece are inhaled to magnetism constitute infrared thermal imager's adsorption plane jointly. Compare in the port of the outstanding cavity that separates the magnetism piece of first end of magnetism part 6 and constitute infrared thermal imaging system's adsorption plane alone, aforementioned arrangement can increase infrared thermal imaging system in the area of the adsorption plane of mounted position department, can strengthen infrared thermal imaging system from this and adsorb the stability in mounted position department.
Referring to fig. 5, in order to reduce the overall thickness of the thermal infrared imager, in one embodiment, the metal back plate 7 is provided with a groove or through hole 9, and the magnetic shielding member is at least partially disposed in the groove or through hole 9. Compare and establish on metal back plate 7 with magnetic isolation piece, establish magnetic isolation piece and can reduce infrared thermal imager's whole thickness in metal back plate 7's recess or through-hole 9 to be convenient for install infrared thermal imager in narrow and small space, for example the regulator cubicle.
The shape of the groove or the through hole 9 can be matched with that of the magnetic isolation piece, and when the magnetic part 6 is arranged on the rear shell 2, the groove or the through hole 9 is arranged on the rear shell 2; the magnetic shielding member can be arranged in the groove or the through hole 9 by dispensing.
Referring to fig. 5 and 6, in order to enable the infrared thermal imaging instrument to be more stably attached to the installation position, in an embodiment, a first end face of the magnetic attraction component 6 is provided with a non-slip pad 10, or an end face of one end of the metal back plate provided with a groove or a through hole is provided with a non-slip pad 10.
The material of slipmat 10 can be silica gel, can fix slipmat 10 on the first terminal surface of magnetism part 6 through the gum, or on the metal backplate, is provided with slipmat 10 between part 6 and the mounted position promptly in magnetism.
The non-slip mat 10 has no ability of shielding magnetic field, so the non-slip mat 10 arranged between the magnetic part 6 and the installation position can not change the strength of the magnetic field generated by the magnetic part 6. Install slipmat 10 between the metal covering of part 6 and mounted position department is inhaled to magnetism, can increase the magnetic friction between the metal covering of part 6 and mounted position department of inhaling to make the more firm absorption of part 6 of inhaling of magnetism on the metal covering of mounted position department, make the absorption that infrared thermal imaging appearance can be more firm in mounted position department.
In one embodiment, the material of the magnetic shield is sus430, mild steel, electrically pure iron, or permalloy.
sus430 is a stainless steel with high magnetic permeability and corrosion resistance. Low carbon steel, also known as mild steel, refers to iron carbon alloys with carbon content below 0.25%, such as Q195, Q215 and Q255. The electrician pure iron is also called industrial pure iron, ingot iron, red iron and the like, and refers to steel with the iron content of more than 99.5 percent, wherein the total impurity content of the electrician pure iron is less than 0.2 percent and the carbon content is 0.02 to 0.04 percent. Permalloy is an iron-nickel alloy, and the nickel content is within the range of 30-90%.
It is understood that the above is an example of the material for the magnetic isolation member, and any desired soft magnetic material can be used as the magnetic isolation member according to the embodiment of the present invention.
Referring to fig. 7, in order to enhance the heat dissipation capability of the infrared thermal imaging camera, in an embodiment, the rear case 2 is made of metal, and a thermal pad 11 or thermal silicone grease is disposed between the printed circuit board 4 and the rear case 2.
