Description

Technical Field

[0001] The present invention belongs to the technical field of measuring instruments, and particularly relates to a radar level gauge with an auxiliary aiming device and a debugging method. Background Art

[0002] In the industrial field, radar level gauges are widely used for liquid level measurement in many bins and water tanks. Radar level gauges are easy to install, simple to operate, have high accuracy, and fast dynamic response, and are the preferred products for level measurement.

[0003] The radar level gauge emits a beam of radar waves. After the radar waves reach the object to be measured, they are reflected back. After the level gauge receives the reflected waves, the distance from the level gauge to the object to be measured is calculated through the time difference between the transmitted wave and the received reflected wave and the propagation speed of the radar waves.

[0004] The measurement principle of the radar level gauge determines that there cannot be any obstacles within its measurement range. The presence of obstacles will generate false echoes and prevent the radar level gauge from working properly. As shown in the accompanying drawings Figure 6 In positions A and B, they may both affect the measurement. However, during the actual installation process, since radar waves cannot be observed by the naked eye, it is unlikely to discover this problem, resulting in inaccurate measurement during later use. Summary of the Invention

[0005] The purpose of the present invention is to solve the problems existing in the prior art, and provide a radar level gauge with an auxiliary aiming device, which can quickly determine the radar wave range, thus facilitating the later debugging of the radar level gauge.

[0006] On the one hand, the present invention provides a radar level gauge with an auxiliary aiming device, including a mounting ring plate. A steering kit is movably arranged through the mounting ring plate. An angle adjustment component is arranged on the steering kit. A radar level gauge body passes through the steering kit. A beam wave shield is arranged on the radar wave transmitting end of the radar level gauge body. A mounting chute parallel to the extending direction of the beam wave shield is opened on the outer surface of the beam wave shield. A laser lamp is arranged in the mounting chute, and the irradiation direction of the laser lamp is parallel to the length extending direction of the mounting chute.

[0007] By mounting multiple laser lamps on the outer wall of the beam wave shield, the included angle between two opposite laser lamps is the same as the central angle of the beam wave shield. Therefore, the irradiation points of the laser lamps are the boundaries of the beam angle of the radar waves. The range of the invisible radar waves can be shown through the laser lamps, thus facilitating the staff to debug the angle of the radar level gauge body, effectively improving the measurement accuracy.

[0008] Optionally, one end of the beam hood close to the radar wave transmitting end is a narrow end, and the other end is a wide end. The central angle of the beam hood is the same as the beam angle of the radar level gauge body.

[0009] In the above technical solution, the narrow end and wide end of the beam hood are designed to optimize the focusing and diffusion characteristics of the radar wave, reduce clutter interference, and improve the signal strength and measurement accuracy. The central angle of the beam hood is consistent with the radar beam angle, ensuring that the indication range of the laser lamp completely matches the actual coverage range of the radar, and enhancing the accuracy of the auxiliary aiming.

[0010] Optionally, the number of the mounting chutes is not less than 4. In this way, the detection range of the radar wave can be made more specific, and at the same time, the laser lamp is allowed to be flexibly installed in different orientations to adapt to the debugging requirements of complex tank structures. Each of the mounting chutes is evenly distributed on the outer surface of the beam hood. One end of the inner wall of the mounting chute close to the radar level gauge body is provided with a first magnetic sheet.

[0011] Optionally, one side of the laser lamp is provided with a mounting slider. A second magnetic sheet that attracts the first magnetic sheet is provided on the surface of the mounting slider in contact with the mounting chute. Through the mutual cooperation of the first magnetic sheet and the second magnetic sheet, the laser lamp can be quickly disassembled, assembled and position-adjusted without tools, simplifying the operation process and improving the debugging efficiency.

[0012] Optionally, the mounting ring plate is a circular ring plate body, and a plurality of mounting screw holes are evenly formed around the inner circle of the mounting ring plate.

[0013] Optionally, the steering kit includes a rotating ring and a load-bearing ring. The rotating ring passes through the inner circle of the mounting ring plate. At the junction of the outer wall of the rotating ring and the inner circle of the mounting ring plate, the load-bearing ring is arranged on the outer periphery of one end of the rotating ring close to the radar level gauge body. A docking ring is arranged on the outer periphery of the other end of the rotating ring. The load-bearing ring and the docking ring are respectively connected to both sides of the mounting ring plate.

[0014] Optionally, the angle adjustment assembly includes two adjustment sleeve rods arranged on the load-bearing ring. The other ends of the two adjustment sleeve rods are jointly provided with an adjustment plate. The two ends of the adjustment sleeve rod are respectively rotatably connected to the load-bearing ring and the adjustment plate. The radar wave transmitting end of the radar level gauge body spirally passes through the middle of the adjustment plate.

[0015] In the above two technical solutions, the horizontal rotation adjustment is realized through the cooperation of the rotating ring and the load-bearing ring, so that the radar level gauge can adjust the direction by 360°, avoiding obstacles on the inner side of the tank. In addition, the two-way rotation design of the adjustment sleeve rod and the adjustment plate is used to support the pitch angle adjustment, further optimizing the coverage path of the radar beam and ensuring that the measurement path is unobstructed.

[0016] Optionally, a steering handle is provided on the side of the load ring. The addition of the steering handle provides an intuitive manual operation point, allowing the steering kit to be quickly rotated without the need for tools, thus enhancing the convenience of debugging.

[0017] Optionally, a lamp group controller is provided on the bottom wall of the adjustment plate. The lamp group controller integrates a power supply and a switch. Connection terminals are provided at the bottom of the lamp group controller, and the lamp group controller is connected to the laser lamp. The lamp group controller integrating the power supply and the switch simplifies the circuit connection, reduces the complexity of external wiring, improves the reliability of the device, and the design of the connection terminals facilitates expansion or integration with other control systems, enhancing functionality.

[0018] On the one hand, the present invention provides a debugging method for a radar level gauge with an auxiliary aiming device, including: Fix the radar level gauge with the auxiliary aiming device to the detection port of the storage tank; Judge whether the axis of the emission end of the radar level gauge is coaxial with the axis of the center of the mounting ring plate; Turn on the lamp group controller and the laser lamp, let the laser lamp emit laser light, and the radar wave range of the radar level gauge body is reflected through the areas irradiated by multiple lasers; Observe the landing points irradiated by the laser lamp to judge whether the inner side wall of the tank or other obstacles are touched within the radar wave range: In the case where the axis of the emission end of the radar level gauge is not coaxial with the axis of the center of the mounting ring plate, if it is determined that the radar wave touches the inner side wall of the tank or other obstacles, then rotate the steering kit, driving the radar level gauge body to rotate synchronously until the inner side wall of the tank or obstacles are no longer touched within the radar wave range; If after the steering kit rotates one week, the radar wave still cannot get rid of the inner side wall of the tank or obstacles, then adjust the two adjusting sleeve rods, change the angle between the radar level gauge body and the mounting ring plate, and cooperate with rotating the steering kit until the radar wave no longer touches the inner wall of the tank or obstacles; In the case where the axis of the emission end of the radar level gauge is coaxial with the axis of the center of the mounting ring plate, if it is determined that the radar wave touches the inner side wall of the tank or other obstacles, then directly adjust the two adjusting sleeve rods, change the angle between the radar level gauge body and the mounting ring plate until the radar wave no longer touches the inner wall of the tank or obstacles.

[0019] Through the above technical solution, through the debugging process of the linkage between laser indication and mechanical adjustment, non-professionals can also quickly complete precise installation, reducing the technical threshold. The step-by-step logic (first rotation adjustment, then angle adjustment) ensures efficient interference elimination, avoids repeated trial and error, and shortens the debugging time. Finally, the whole method is standardized, effectively reducing human errors and improving the consistency of measurement results.

[0020] Compared with the prior art, the beneficial effects of the present invention are: 1. Through the combined design of the beam hood and the laser light, the abstract radar beam range is visualized, allowing the installer to directly observe the radar wave coverage area and avoid measurement errors caused by the beam touching the wall or obstacles; 2. The combination of the steering kit and the angle adjustment component enables the radar level meter body to achieve dual adjustment of the horizontal and pitch angles, flexibly avoid the inner wall or obstacles of the tank, and improve the wide range of applicable scenarios; 3. The mounting ring plate provides a stable mounting base to ensure the overall stability of the equipment and reduce measurement deviations caused by vibration or offset; 4. The narrow and thick ends of the beam hood are designed to optimize the focusing and diffusion characteristics of radar waves, reduce clutter interference, and improve signal strength and measurement accuracy. The central angle of the beam cover is consistent with the radar beam angle, ensuring that the indication range of the laser light is fully matched with the actual coverage range of the radar, thereby enhancing the accuracy of auxiliary aiming; 5. Through the cooperation between the first magnetic sheet and the second magnetic sheet, the laser light can be quickly disassembled and adjusted without tools, simplifying the operation process and improving the debugging efficiency; 6. Through the cooperation of the rotating circle and the carrier ring, horizontal rotation adjustment can be achieved, so that the radar level meter can adjust its direction 360° to avoid obstacles inside the tank. In addition, the two-way rotation design of the adjustment sleeve and the adjustment plate supports pitch angle adjustment, further optimizing the coverage path of the radar beam and ensuring that the measurement path is obstacle-free.

DETAILED DESCRIPTION

[0023] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0024] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "middle", "upper", "lower", "left", "right", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present invention.

[0025] As Figure 1 shown, on the one hand, the present invention provides a radar level gauge with an auxiliary aiming device, including a mounting ring plate 1. A steering kit 2 is movably passed through the mounting ring plate 1 on the mounting ring plate 1. An angle adjustment component is provided on the steering kit 2. A radar level gauge body 6 is provided on the angle adjustment component and passes through the steering kit 2. A beam focusing cover 7 is provided on the radar wave transmitting end 61 of the radar level gauge body 6. A mounting chute 8 parallel to the extension direction of the beam focusing cover 7 is opened on the outer surface of the beam focusing cover 7. A laser lamp 9 is arranged in the mounting chute 8. The irradiation direction of the laser lamp 9 is parallel to the length extension direction of the mounting chute 8.

[0026] By mounting a plurality of laser lamps 9 on the outer wall of the beam focusing cover 7, the included angle between two opposite laser lamps 9 is the same as the central angle of the beam focusing cover 7. Therefore, the irradiation points of the laser lamps 9 are the boundaries of the beam angle of the radar wave. The range of the invisible radar wave to the naked eye can be displayed through the laser lamps 9, which is convenient for the staff to debug the angle of the radar level gauge body 6, thereby effectively improving the measurement accuracy.

[0027] In this embodiment, one end of the beam focusing cover 7 close to the radar wave transmitting end 61 is a narrow end, and the other end is a wide end. The narrow end and the wide end of the beam focusing cover 7 are designed to optimize the focusing and diffusion characteristics of the radar wave, reduce clutter interference, and improve the signal strength and measurement accuracy. The central angle of the beam focusing cover 7 is the same as the beam angle of the radar level gauge body 6 to ensure that the indication range of the laser lamp 9 completely matches the actual coverage range of the radar, enhancing the accuracy of the auxiliary aiming.

[0028] Specifically: The inner diameter of the narrow end of the beam shroud 7 is 25 mm, which is threadedly connected to the radar wave transmitting end 61; the inner diameter of the wide end is 50 mm, and the length is 120 mm. It is made of polytetrafluoroethylene material, with both high temperature resistance and low dielectric loss characteristics. The central angle of the beam shroud 7 is 30°, which is consistent with the beam angle of the radar level gauge body 6, ensuring that the laser indication range completely coincides with the actual radar wave coverage range.

[0029] As Figures 1 - 5 shown, in this embodiment, the number of mounting chutes 8 is not less than 4. This can make the detection range of the radar wave more visualized, and at the same time allows the laser lamp 9 to be flexibly installed in different orientations to adapt to the debugging requirements of complex tank structures. Each mounting chute 8 is evenly distributed on the outer surface of the beam shroud 7. One end of the inner wall of the mounting chute 8 close to the radar level gauge body 6 is provided with a first magnetic sheet 81.

[0030] In this embodiment, one side of the laser lamp 9 is provided with a mounting slider 91. The surface of the mounting slider 91 in contact with the mounting chute 8 is provided with a second magnetic sheet 911 that attracts the first magnetic sheet 81. Through the mutual cooperation of the first magnetic sheet 81 and the second magnetic sheet 911, the laser lamp 9 can be quickly disassembled, assembled, and position-adjusted without tools, simplifying the operation process and improving the debugging efficiency.

[0031] Specifically: The laser lamp 9 selects a red visible laser with a wavelength of 635 nm and a power of 5 mW, meeting the Class 2 safety standard. The first magnetic sheet 81 on the inner wall of the mounting chute 8 is a neodymium iron boron permanent magnet, and the second magnetic sheet 911 of the mounting slider 91 is a soft magnetic alloy. The two cooperate to achieve the rapid adsorption and sliding positioning of the laser lamp 9. The spacing of the laser lamps 9 can be adjusted according to actual needs, with a minimum spacing of 10 mm and a maximum spacing of 50 mm, adapting to the debugging requirements of different tank diameters.

[0032] In this embodiment, the mounting ring plate 1 is a circular ring plate body. The mounting ring plate 1 is evenly provided with a plurality of mounting screw holes around the inner circle. The mounting ring plate 1 is made of high-strength aluminum alloy material, and its surface is anodized to enhance corrosion resistance. Its inner diameter is 150 mm, the outer diameter is 200 mm, and the thickness is 10 mm. The mounting ring plate 1 is evenly provided with 8 M6 mounting screw holes around the inner circle, and the screw hole spacing is 45°. It can be fixed to the flange of the storage tank inspection port through bolts to ensure stable installation.

[0033] In this embodiment, the steering kit 2 includes a rotating ring and a load-bearing ring. The rotating ring passes through the inner circle of the mounting ring plate 1. At the junction of the outer wall of the rotating ring and the inner circle of the mounting ring plate 1, the load-bearing ring is arranged on the outer periphery of one end of the rotating ring close to the radar level gauge body 6. A docking ring 21 is arranged on the outer periphery of the other end of the rotating ring. The load-bearing ring and the docking ring 21 are respectively in contact with both sides of the mounting ring plate 1.

[0034] It should be noted that a damping collar is provided on the outer wall of the rotating circle, and the damping collar increases the friction resistance between the rotating circle and the mounting ring plate 1 , so that the rotating circle will not rotate automatically, thereby changing the angle of the radar level meter body 6 .

[0035] Preferably, Figure 3 As shown, the rotating ring and the docking ring 21 are connected by threads. As the docking ring 21 is tightened, the resistance between the docking ring 21 and the mounting ring plate 1 increases, and the rotating ring cannot be rotated. When the steering kit 2 needs to be rotated, the docking ring 21 only needs to be rotated in the opposite direction to loosen the docking ring 21 and the mounting ring plate 1, and the rotating ring can be rotated at will, thereby realizing the direction adjustment of the steering kit 2.

[0036] In this embodiment, the outer wall of the rotating circle of the steering kit 2 is provided with a damping ring made of polyurethane, with a friction coefficient of 0.4, to ensure that the rotating circle remains stationary without external force. The load ring and the docking ring 21 are cast with 304 stainless steel, and a steering handle 3 is welded on the outside of the load ring. The handle is 80mm long and has anti-slip grooves on the surface for easy manual rotation. The docking ring 21 is connected to the mounting ring plate 1 through an M8 thread with a thread depth of 15mm. After tightening, it can generate a locking torque of about 20N·m to prevent the steering kit 2 from rotating accidentally.

[0037] like Figure 3 As shown, the angle adjustment assembly includes two adjustment sleeve rods 4 arranged on the carrier ring, and the other ends of the two adjustment sleeve rods 4 are jointly provided with an adjustment plate 5, and the two ends of the adjustment sleeve rods 4 are rotatably connected with the carrier ring and the adjustment plate 5 respectively, and the radar wave transmitting end 61 of the radar level meter body 6 spirally passes through the middle part of the adjustment plate 5.

[0038] It should be noted that a rotation limiting seat is provided at both the bottom and top of the adjusting sleeve 4. The rotation limiting seat includes a base, the inner wall of which is provided with a rotatable shaft, and one end of the adjusting sleeve 4 is sleeved on the surface of the shaft, so that the adjusting sleeve 4 can only rotate along the direction of rotation of the shaft, thereby ensuring the stability of the adjusting plate 5.

[0039] In addition, a threaded hole is provided in the center of the adjusting plate 5 , and in order to increase the connection strength between the adjusting plate 5 and the radar wave transmitting end 61 of the radar level meter body 6 , reinforcement kits are provided on both sides of the adjusting plate 5 to increase the contact area with the radar wave transmitting end 61 .

[0040] Specifically, in this embodiment, the adjusting sleeve rod 4 includes a sleeve on the surface and a threaded rod spirally arranged inside the sleeve. The sleeve is a hollow stainless steel pipe with an outer diameter of 12 mm and a wall thickness of 1.5 mm. The threaded rod is a steel bar with an outer diameter of 9 mm, and threads are provided on the surface. Both ends of the adjusting sleeve rod 4 are connected to the load-bearing ring and the adjusting plate 5 through rotation-limiting seats. The shaft diameter of the rotation-limiting seat is 6 mm, and it is designed with a self-lubricating copper sleeve, and the rotation angle range is ±45°. The threaded hole in the center of the adjusting plate 5 is an M20×1.5 standard thread, which is matched with the radar wave transmitting end 61. The strengthening kits on both sides are annular stainless steel gaskets with a thickness of 2 mm, and are fixed to the adjusting plate 5 through bolts to increase the contact area to prevent loosening.

[0041] In this embodiment, the radar wave transmitting end 61 is cylindrical and has threads on the surface. In addition, the radar wave transmitting end 61 and the narrow end of the beam focusing cover 7 are threadedly connected, so that the mutual replacement of the radar level gauge body 6 and the beam focusing cover 7 can be easily realized.

[0042] In this embodiment, the horizontal rotation adjustment is realized through the cooperation of the rotating ring and the load-bearing ring, so that the radar level gauge can adjust the direction by 360°, avoiding the obstacles inside the tank. In addition, by using the two-way rotation design of the adjusting sleeve rod 4 and the adjusting plate 5, the pitch angle adjustment is supported, further optimizing the coverage path of the radar beam and ensuring that the measurement path is unobstructed.

[0043] In this embodiment, a steering handle 3 is provided on the side of the load-bearing ring. The addition of the steering handle 3 provides an intuitive manual operation point, and the steering kit 2 can be quickly rotated without the aid of tools, improving the debugging convenience.

[0044] In this embodiment, a lamp group controller 10 is provided on the bottom wall of the adjusting plate 5. The lamp group controller 10 integrates a power supply and a switch. Connection terminals are provided at the bottom of the lamp group controller 10. The lamp group controller 10 is connected to the laser lamp 9. The lamp group controller 10 integrating the power supply and the switch simplifies the circuit connection, reduces the complexity of external wiring, improves the reliability of the device, and the connection terminal design facilitates expansion or integration with other control systems, enhancing the functionality.

[0045] On the one hand, based on the same technical concept of the above embodiment, the present invention provides a debugging method for a radar level gauge with an auxiliary aiming device, including: Fix the radar level gauge with the auxiliary aiming device to the detection port of the storage tank; Judge whether the axis line of the transmitting end of the radar level gauge and the center axis of the mounting ring plate 1 are coaxial; Turn on the lamp group controller 10 and the laser lamp 9, let the laser lamp 9 emit laser light, and the radar wave range of the radar level gauge body is reflected through the areas irradiated by multiple lasers; Observe the landing points irradiated by the laser lamp 9 to judge whether the inner side wall of the tank or other obstacles are touched within the radar wave range: When the axis of the transmitting end of the radar level gauge is not coaxial with the center axis of the mounting ring plate 1, if it is determined that the radar wave touches the inner wall of the tank or other obstacles, rotate the steering kit 2 to drive the radar level gauge body 6 to rotate synchronously until the radar wave no longer touches the inner wall of the tank or obstacles within the radar wave range; If after the steering kit 2 rotates one full circle, the radar wave still cannot get rid of the inner wall of the tank or obstacles, adjust the two adjusting rods 4 to change the angle between the radar level gauge body 6 and the mounting ring plate 1, and cooperate with rotating the steering kit 2 until the radar wave no longer touches the inner wall of the tank or obstacles; When the axis of the transmitting end of the radar level gauge is coaxial with the center axis of the mounting ring plate 1, if it is determined that the radar wave touches the inner wall of the tank or other obstacles, directly adjust the two adjusting rods 4 to change the angle between the radar level gauge body 6 and the mounting ring plate 1 until the radar wave no longer touches the inner wall of the tank or obstacles; After the debugging is completed, turn off the laser lamp 9 and start the radar level gauge for actual measurement. If the signal strength is lower than the threshold value, the threaded connection depth between the beam hood 7 and the radar wave transmitting end 61 can be finely adjusted (the recommended adjustment range is ±2 mm) to optimize the beam focusing effect.

[0046] Through the above technical solutions, through the debugging process of the linkage between laser indication and mechanical adjustment, non-professionals can also quickly complete accurate installation, reducing the technical threshold. The step-by-step logic (first rotation adjustment, then angle adjustment) ensures efficient interference elimination, avoids repeated trial and error, and shortens the debugging time. Finally, the entire method is standardized, effectively reducing human errors and improving the consistency of measurement results.

[0047] It should be noted that the method for judging whether the axis of the transmitting end of the radar level gauge is coaxial with the center axis of the mounting ring plate 1 is to observe whether the extension lengths of the two adjusting rods 4 are the same after the mounting ring plate 1 is installed. If the extension lengths of the two adjusting rods 4 are the same, it means that the axis of the transmitting end of the radar level gauge is coaxial with the center axis of the mounting ring plate 1; otherwise, they are not coaxial.

[0048] Application scenario examples: Dome storage tank: For the installation scenario at the top of the dome tank, adjust the pitch to make the radar wave avoid the support beam, and use the laser indication to ensure that the beam vertically covers the liquid surface.

[0049] Reaction tank with agitator: Horizontally rotate the radar level gauge to the stirring blind area to avoid the reflection interference of the stirring paddle. At the same time, calibrate the real-time monitoring beam offset through multiple laser lamps 9.

[0050] The working principle of the above embodiments is as follows: The radar level gauge with an auxiliary aiming device of the present invention realizes the precise positioning and debugging of the radar beam through the synergistic effect of the laser lamp 9 and the mechanical adjustment assembly. During operation, the radar level gauge is fixed at the detection port of the storage tank. After the laser lamp 9 is turned on, it emits a laser, and the irradiation area intuitively shows the coverage range of the radar wave. The staff can judge whether the radar wave touches the inner wall of the tank or other obstacles by observing the laser indication. If an obstacle is touched, first, the horizontal rotation adjustment is carried out through the steering kit 2 to avoid the obstacle. If the horizontal rotation cannot solve the problem, the elevation angle of the radar level gauge is adjusted by using the angle adjustment assembly, combined with the horizontal rotation, until the radar beam completely avoids interference. After the debugging is completed, the laser lamp 9 is turned off, and the radar level gauge is started for actual measurement. If the measurement signal strength is insufficient, the threaded connection depth between the beam wave cover 7 and the radar wave transmitting end 61 can also be finely adjusted to further optimize the beam focusing effect. The whole process realizes the precise positioning and debugging of the radar beam with the linkage of laser indication and mechanical adjustment, reduces the debugging difficulty, and improves the measurement accuracy and consistency.

[0051] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made in these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.

A debugging method for a radar level gauge with an auxiliary aiming device, characterized in that: It includes: Fix the radar level gauge with an auxiliary aiming device to the detection port of the storage tank; Judge whether the axis line of the emission end of the radar level gauge is coaxial with the center axis of the installation ring plate; Turn on the lamp group controller and the laser lamp to make the laser lamp emit laser light, and reflect the radar wave range of the radar level gauge body through the areas irradiated by multiple lasers; Observe the landing points irradiated by the laser lamp to judge whether the inner side wall of the tank or other obstacles are touched within the radar wave range: In the case that the axis line of the emission end of the radar level gauge is not coaxial with the center axis of the installation ring plate, if it is determined that the radar wave touches the inner side wall of the tank or other obstacles, then rotate the steering kit to drive the radar level gauge body to rotate synchronously until the inner side wall of the tank or obstacles are no longer touched within the radar wave range; If after the steering kit rotates one full circle, the radar wave still cannot get rid of the inner sidewall of the tank or obstacles, adjust the two adjusting sleeve rods to change the angle between the radar level gauge body and the mounting ring plate, and cooperate with rotating the steering kit until the radar wave no longer touches the inner wall of the tank or obstacles; When the axis line of the transmitting end of the radar level gauge is coaxial with the center axis of the mounting ring plate, if it is determined that the radar wave touches the inner sidewall of the tank or other obstacles, directly adjust the two adjusting sleeve rods to change the angle between the radar level gauge body and the mounting ring plate until the radar wave no longer touches the inner wall of the tank or obstacles.
