[0029] The specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure.

[0030] As shown in the specific embodiments of the present disclosure, Figures 1-3 The present disclosure provides an explosion-proof radar level scanner, which comprises a shell 1 and a radar body located in the shell 1, and a conductive structure 4 is arranged on the outer surface of the shell 1, which is used to divide the shell 1 into multiple anti-static areas and guide the static electricity accumulated in the multiple anti-static areas to a grounding end.

[0031] Specifically, the outer surface of the shell 1 comprises a metal area 11 and a non-metal area 12, and the conductive structure 4 is arranged on the non-metal area 12, which divides the non-metal area 12 into multiple anti-static areas.

[0032] The conductive structure 4 is connected with the grounding end, so that the static electricity accumulated in the anti-static area can be guided to the grounding end through the conductive structure 4; or the conductive structure 4 is connected with the metal area 11, and the metal area 11 is connected with the grounding end, so that the static electricity accumulated in the anti-static area is first guided to the metal area 11 through the conductive structure 4, and then guided to the grounding end through the metal area 11, so that the radar level scanner of the present disclosure meets the explosion-proof requirement and the working condition safety requirement.

[0033] The explosion-proof radar level scanner of the present disclosure divides the non-metal area 12 into multiple anti-static areas to guide the static electricity accumulated on the outer surface in time, so that each anti-static area meets the explosion-proof requirement, and the size of each anti-static area also meets the working condition safety requirement.

[0034] The conductive structure 4 can be arranged on the outer surface of the shell 1 by welding or pressing, etc., which is used to guide the static electricity accumulated on the shell 1 to the grounding end or the outside of the radar shell 1.

[0035] For the scheme that the conductive structure 4 is arranged on the outer surface of the shell 1 by pressing, the explosion-proof radar level scanner of the present disclosure further comprises a pressing device arranged on the outer surface of the shell 1, which is used to press the conductive structure 4 on the surface of the shell 1.

[0036] Specifically, the pressing device comprises a pressing base 2 and a plurality of pressing blocks 3, the pressing base 2 is sleeved on the outer surface of the shell 1; a plurality of pressing blocks 3 are arranged above the pressing base 2, which are used to fix and press the conductive structure 4 on the non-metallic area 12 of the outer surface of the shell 1. Wherein, the pressing base 2 can be sleeved on the metal area 11, or can be sleeved at the position where the non-metallic area 12 and the metal area 11 meet, as long as the pressing base 2 can be connected with the conductive medium, so that the static electricity accumulated in the anti-static area of the non-metallic area 12 can be guided to the grounding end or the outside of the radar level scanner in time, so that the radar level scanner meets the safety requirements of working conditions.

[0037] In the present disclosure, the pressing device is provided as the pressing base 2 and a plurality of pressing blocks 3, wherein the conductive structure 4 can be initially pressed onto the non-metallic area 12 by the pressing base 2, and then further pressed onto the non-metallic area 12 from multiple directions by a plurality of pressing blocks 3, so that the conductive structure 4 is pressed onto the non-metallic area 12, so that the non-metallic area 12 can form a plurality of anti-static areas, thereby the static electricity accumulated on the non-metallic area 12 during use can be discharged outward in time, reducing the occurrence of dangerous accidents, and improving the safety of the radar level scanner.

[0038] After the conductive structure 4 is secondarily pressed onto the non-metallic area 12, the pressing block 3 needs to be fixed to prevent movement. Therefore, a plurality of mounting grooves are formed on the pressing base 2 in the present disclosure, the number of the mounting grooves matches the number of the pressing blocks 3; the pressing block 3 is provided with a through hole, and the pressing block 3 is fixed to the mounting groove through the through hole by a fixing piece 5.

[0039] Further, the pressing block 3 has a certain volume, and the size of the conductive structure 4 may also be different, in order to press the conductive structure 4 of different sizes onto the non-metallic area 12 by the pressing block 3, the through hole on the pressing block 3 needs to be set as follows. Specifically, the through hole on the pressing block 3 is set as a strip hole opened in the moving direction of the non-metallic area 12, and the strip hole is used to adjust the position of the pressing block 3 on the pressing base 2 according to the pressing degree of the conductive structure 4.

[0040] The through hole on the pressing block 3 is provided as a strip-shaped hole, the long side of the strip-shaped hole is arranged along the direction in which the non-metallic area 12 moves, and the short side of the strip-shaped hole matches the size of the fixing piece 5 that fixes the pressing block 3 to the pressing base 2. Since the fixing of the pressing block 3 to the pressing base 2 through the fixing piece 5 is a dynamic process, the conductive structure 4 is gradually fixed to the non-metallic area 12 from loose to tight. To this end, the provision of the strip-shaped hole on the pressing block 3 can meet the requirement of pressing the conductive structure 4 to the non-metallic area 12.

[0041] Specifically, the plurality of mounting grooves provided in the pressing base 2 can be threaded holes, and correspondingly, the fixing piece 5 that fixes the pressing block 3 to the pressing base 2 can be a nut structure. That is, the nut is passed through the strip-shaped through hole on the pressing block 3, and then is tightened in the threaded hole provided in the pressing base 2, so as to fasten the pressing block 3 to the pressing base 2.

[0042] The radar level scanner of the present disclosure needs to limit the surface size of the non-metallic area 12 within a certain safety range to meet the safety requirements of working conditions, and also needs to limit the amount of static electricity accumulated on the surface of the non-metallic area 12 within a safety range.

[0043] The specific structure of the conductive structure 4 and the process of pressing it to the non-metallic area 12 on the outer surface of the shell 1 are described as follows.

[0045] The conductive structure 4 in the present disclosure can be a metal wire. On the one hand, since the size of the wire is small, the influence on the transmitting and receiving beams of the radar level scanner can be reduced. On the other hand, since the wire can conduct electricity, the static electricity accumulated on the non-metallic area 12 can be conveniently guided to the outside or the grounding end, for example, the static electricity can be first guided to the conductive metal area 11, and then guided to the ground or other external devices of the radar level scanner through the grounding end connected to the metal area 11 through the wire.

[0046] In the present disclosure, the metal area 11 of the shell 1 is preferably provided as a conductive material, so that the static electricity discharged by the conductive structure 4 can be indirectly discharged to the grounding end or the ground or other external devices of the radar level scanner. Generally, the radar level scanner is installed on a container through a flange, and the container is generally a non-conductive container, for example, the container can be a coal bunker.

[0047] In order to minimize the influence of the guide wire on the transmitting and receiving beam, one of the plurality of anti-static regions is arranged at the central region of the non-metallic region 12, which is the transmitting and receiving beam region.

[0048] Specifically, the non-metallic region 12 has a certain curvature, as shown in Figures 1-3 which is a semi-spherical shape or a shape close to a semi-spherical shape. In order to enable the guide wire to be fixed and stable on the non-metallic region 12, at least one of the guide wires passes through the pressing block 3 arranged on one side of the non-metallic region 12, the central region of the non-metallic region 12, and another pressing block 3 arranged on the other side of the non-metallic region 12.

[0049] Further, the radar level scanner of the present disclosure can further comprise a balancing piece 6 arranged at the central region of the non-metallic region 12, which is arranged as a horizontal plane, and the size of the horizontal plane matches the balancing piece 6. The balancing piece 6 is provided with a guide wire hole, and the guide wire passes through the pressing block 3 on one side of the non-metallic region 12, the guide wire hole on the balancing piece 6 at the central region of the non-metallic region 12, and the pressing block 3 on the other side of the non-metallic region 12 to be tightly attached to the non-metallic region 12.

[0050] As shown in Figures 1-2 , the pressing base 2 is provided with four pressing blocks, two guide wires are arranged in a cross shape, the balancing piece 6 is provided with four guide wire holes corresponding to the four directions of the cross shape and the four pressing blocks, one of the guide wires passes through the pressing block one, the guide wire hole one and the guide wire hole two, and the pressing block two to be wound on the non-metallic region 12, and the other guide wire passes through the pressing block three, the guide wire hole three and the guide wire hole four, and the pressing block four to be wound on the non-metallic region 12. The two guide wires are arranged in a cross shape, and the guide wire is preferably wound at least one turn on the guide wire hole and the wire end needs to be tightly attached to the non-metallic region 12, so as to ensure that the plurality of regions formed by the guide wire are anti-static regions, and the size of each region meets the anti-explosion requirement.

[0051] The preferred embodiments of the present disclosure are described in detail in combination with the drawings, but the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all belong to the protection scope of the present disclosure.
