Fig. 2 is a schematic view of a prior art protective device.
The heat insulation cover comprises a cover body, a heat insulation layer, a pressing ring and a mounting edge, wherein the cover body is provided with the mounting edge, the heat insulation layer and the pressing ring.
Detailed Description
As shown in fig. 1, a material level radar protection cover suitable for a high temperature environment comprises a cover body 2, wherein one end of the cover body 2 adopts an arc structure, the arc structure can be a hemisphere or the like, the other end of the cover body 2 can be a cylinder or the like, and the length of the cylinder is set according to specific needs. The other end of the cover body is connected with an external structure in an installation mode, the external structure refers to parts such as a high-temperature protection pipeline and the like outside the radar robot, a connecting edge extends from the other end of the cover body, bolt holes are formed in the connecting edge, and the cover body 2 is made of a wave-transmitting high polymer material. One end of the cover body 2 adopts an arc-shaped structure, so that dust and superposition of dust can be prevented, the dust can fall off freely under the action of gravity, and the interference of the dust on radar signals is reduced. The cover body 2 is additionally provided with a heat insulation layer 3. The addition of the heat insulating layer 3 can provide the cover 2 with a high temperature preventing effect. The cover body is made of pure tetrafluoro or polyether-ether-ketone. The material selection of the pure tetrafluoro or polyether-ether-ketone can well ensure the temperature requirement of the cover body at high temperature.
The heat insulation layer 3 is arranged on the outer wall of the arc-shaped structure of the cover body 2. The arc structure of the cover body 2 is different from the inclined plate design in the prior art protective device, simulates the arc structure of the radar antenna, and is convenient for the emission of radar antenna signals.
The heat insulation layer 3 is completely wrapped and attached to the outer wall of the cover body 2. The design of wrapping and attaching the heat insulation layer 3 prevents dust fall and can better insulate heat.
The heat insulation layer 3 is an interlayer combination of high-temperature cloth and a high-temperature material coating. The high temperature cloth is high temperature resistant cloth, the high temperature material coating is high temperature resistant material coated on the high temperature cloth, the interlayer combination body can be formed by brushing 1 or 2 or 3 layers of high temperature material coating on two sides of the high temperature cloth, or can be formed by brushing the high temperature coating on 2 layers of high temperature cloth for adhesion, and the like. The specific high temperature resistant grade is selected according to the high temperature in the material bin body. When the temperature in the material bin is 230-380 ℃, the added high-temperature cloth enhances the high-temperature resistance and impact resistance of the protective cover. The design not only meets the current working condition requirements, but also can detect the moving radar antenna into the bin body for measurement. Meanwhile, the radar antenna is not affected by the severe environment. The signal of the radar antenna can emit electromagnetic waves from any position below the radar level (including the level and the horizontal line), and the design can ensure the measurement of the whole bin.
The protective cover can bear the inert gas pressure of 0.45MPa, and the problem that the radar antenna cannot work normally due to the heat radiation effect in the storage bin is solved.
