Description

Technical Field

[0001] The utility model belongs to the field of liquid level meter equipment, in particular to a firmly installed radar liquid level meter. Background Art

[0002] Radar level meter is an instrument that uses radar technology to measure liquid level. It calculates the height of the liquid level by emitting electromagnetic waves to the measured medium and receiving the reflected electromagnetic waves. Radar level meter is widely used in liquid level measurement in industries such as petroleum, chemical, electric power, metallurgy, and pharmaceuticals. It can measure the liquid level of various liquid media, such as oil tanks, storage tanks, reactors, rivers, reservoirs, etc. In practical applications, radar level meter can be integrated with other automation equipment to realize automatic control and monitoring of liquid level.

[0003] When installing the current radar level meter, the connection flange is usually used for basic fixed connection. However, this connection method has some disadvantages, which can easily lead to loose installation. In actual use, the installation of the connection flange of the radar level meter requires certain skills and experience. If it is not installed properly, it may cause the seal between the flanges to be loose, thus affecting the measurement accuracy of the level meter. This is because there is a lack of firm fixing parts. The lack of firm fixing parts will not only lead to the above problems, but also the connection method of the connection flange is easily affected by external factors, such as vibration, impact, etc., which may cause the connection to loosen, thereby affecting the stability and reliability of the level meter. Therefore, it is necessary to propose a new structure to solve the above technical problems. Utility Model Content

Installed with the horn antenna 140, a connecting flange 210 is installed on the upper surface of the tank body 200, and two fixing components are symmetrically installed through the surface of the connecting flange 210. The fixing components include: a knob head 320, a threaded rod 310, a hinge 330 and an abutment 340. The upper end of the threaded rod 310 is threadedly connected with the knob head 320, and the lower surface of the connecting flange 210 is installed with the hinge 330 through the fixing plate 220, and the inner surface of the hinge 330 is hinged with the abutment 340.

[0022] See also Figures 1 to 3 As the first embodiment of the utility model: a housing 100 is installed at the center of the upper surface of the connecting flange 130, a radar liquid level control chip is installed inside the housing 100, two cable members 110 are symmetrically installed on the outer surface of the housing 100, a reference member 120 is installed below the two cable members 110, and the diameter of the connecting flange 130 is smaller than the diameter of the connecting flange 210;

[0023] The horn antenna 140 at the center of the lower surface of the connecting flange 130 is electrically connected to the radar liquid level control chip inside the housing 100, and the fixing holes 131 and the mounting holes 132 on the upper surface of the connecting flange 130 match the fixing holes 131 and the mounting holes 132 on the upper surface of the connecting flange 210 in structure and position;

[0024] When in use, the user first installs the connecting flange 130 on the upper surface of the connecting flange 210, aligns the mounting hole 132 and the fixing hole 131 of the connecting flange 130 with the mounting hole 132 and the fixing hole 131 of the connecting flange 210, and after alignment, uses bolts with the fixing holes 131 to connect the connecting flange 130 with the connecting flange 2 210. When connecting, pay attention to correcting the horizontal angle of the installation through the reference part 120 on the surface of the shell 100 to avoid tilted installation (the surface of the radar level meter comes with a reference part 120, and the working principle and specific structure of the radar level meter are both existing technologies, which are not described here). Since the connection and fixation of the connecting flange 130 and the connecting flange 2 210 provide a reliable installation foundation, it ensures that the radar level meter can remain stable under various working conditions, reducing measurement errors or equipment damage caused by vibration, shaking, etc.

[0025] See also Figures 1 to 3 As a second embodiment of the present utility model: the diameter of the fixing hole 131 on the surface of the connecting flange 130 is the same as the diameter of the threaded rod 310, the inner wall of the fixing hole 131 is provided with a thread, the connecting flange 130 and the connecting flange 210 are connected to each other through the fixing hole 131 and the fixing bolts, and the connecting flange 130 and the connecting flange 210 are internally connected with the threaded rod 310 through the mounting hole 132;

[0026] The lower end of the threaded rod 310 is rotatably connected to the upper surface of the hinge 330, and the outer surface of the threaded rod 310 is threadedly connected with an abutment 340, and the lower surface of the connecting flange 210 is symmetrically equipped with two fixing plates 220;

[0027] The inner surface of the fixing plate 220 is connected to the abutment member 340, and the center of the abutment member 340 is hingedly connected to the hinge member 330. The abutment member 340 and the hinge member 330 are both L-shaped structures, and one end of the abutment member 340 away from the hinge end abuts against the inner wall of the tank body 200;

[0028] When in use, when the connecting flange 130 is connected to the connecting flange 210, the knob head 320 at the upper end of the threaded rod 310 is not connected to the threaded rod 310 to avoid delaying the connection between the connecting flange 130 and the connecting flange 210. When the connecting flange 130 is connected to the connecting flange 210, the threaded rod 310 in the internal mounting hole 132 of the connecting flange 210 will penetrate the mounting hole 132 on the surface of the connecting flange 130 (no thread is provided inside), and then the connecting flange 130 and the connecting flange 210 are connected and fixed according to the operating steps of the previous embodiment. After the fixing is completed, the user can thread the knob head 320 onto the upper end of the threaded rod 310, and the user can rotate the knob head 320, and the knob head 320 drives the threaded rod 310 to rotate The screw rod 310 is moved so that the abutment 340 on the surface of the screw rod 310 can move, so that the end of the abutment 340 away from the screw rod 310 can abut against the inner wall of the tank body 200, thereby completing the fixation. When disassembling, it is only necessary to perform the above steps in reverse. By setting a fixing component and using it in combination with the connecting flange 130 and the connecting flange 210, multiple fixations and tightening can be achieved. The knob head 320 is convenient for the operator to perform manual adjustment. By rotating the knob head 320, the screw rod 310 is driven to rotate, and then the abutment 340 is pushed to move, so that the abutment 340 is further tightened to the inner wall of the tank body 200, which can enhance the firmness of the installation and ensure that the radar level meter can still work stably under various complex working conditions, such as vibration, impact and the like, and reduce measurement deviations or equipment failures caused by loose installation.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
