Description

Technical Field

[0001] The utility model relates to the technical field of liquid level measurement, in particular to a radar liquid level meter which can be quickly disassembled and assembled and an installation structure. Background Art

[0002] Radar level meter is a general-purpose radar level meter. It is a measuring instrument based on the time travel principle. Radar waves run at the speed of light, and the running time can be converted into a level signal through electronic components. The probe emits a high-frequency pulse that propagates at the speed of light in space. When the pulse encounters the surface of the material, it is reflected back and received by the receiver in the instrument, and the distance signal is converted into a level signal.

[0003] The radar level meter is based on the time domain reflectometry principle (TDR). The electromagnetic pulse of the radar level meter propagates along the steel cable or probe at the speed of light. When encountering the surface of the medium to be measured, part of the pulse of the radar level meter is reflected to form an echo and returns to the pulse transmitter along the same path. The distance between the transmitter and the surface of the medium to be measured is proportional to the propagation time of the pulse between them, and the liquid level height is calculated.

[0004] Since the existing radar level gauge is installed by flange stud bolt connection, and the connection is reliable, after long-term use, if the bolts are not regularly maintained, they will be seriously corroded, making it difficult to disassemble the radar level gauge, greatly increasing the labor intensity of disassembling the radar level gauge, and there are risk factors such as personnel being hit or squeezed by tools during the disassembly of the radar level gauge. At the same time, the radar level gauge body may be damaged, reducing the service life of the equipment.

[0005] A utility model patent with announcement number CN216383348U discloses a quick-install radar level gauge bracket, which is characterized in that it includes a radar level gauge body, a support tube, a rotating connection disk, a locking bolt, a base, a limit baffle and a square block; the bottom of the radar level gauge body is fixedly connected to the top of the support tube, and a threaded section is processed on the outer surface of the bottom of the support tube, the rotating connection disk is disc-shaped, and a circular boss is provided at the center of the upper surface of the rotating connection disk, and a hole is provided at the center of the upper surface of the boss, and a thread is processed at the top of the hole, the bottom of the support tube is threadedly connected to the hole on the rotating connection disk, and the rotating connection disk is threaded along the outer circumference. Two square blocks are evenly arranged on the surface, and a threaded hole is arranged at the center of the upper surface of each square block. A blind hole is processed at the center of the upper surface of the base, and two square blind holes are evenly processed at the edge of the upper surface of the blind hole in the circumferential direction, and the two square blind holes are symmetrically arranged. An annular track is processed on the inner wall of the blind hole on the base, and two limit baffles are arranged inside the annular track, and the two limit baffles are staggered. Two through holes are arranged on the upper surface of the base in the circumferential direction, and the two through holes are symmetrically arranged. A locking bolt is arranged inside each through hole. The rotating connecting disk is inserted into the blind hole of the base, and the rotating connecting disk is detachably connected to the base through the locking bolt. When using this patent to install the radar level meter, the base needs to cooperate, and the base needs to be welded on the container to be measured. Therefore, the welding and disassembly of the base increases the difficulty of the entire process of disassembly and assembly of the radar level meter, and it is easy to cause damage to the container to be measured during the welding and disassembly of the base.

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the utility model.

[0027] During the installation of the radar level meter on the container, the flange on the radar level meter is generally fixedly connected to the flange at the opening of the measured container by bolts. After long-term use, if the bolts are not regularly maintained, they will be seriously corroded, making it difficult to disassemble the radar level meter, greatly increasing the labor intensity of disassembling the radar level meter. When solving the above problems, technicians in this field usually adopt a method of setting a connecting device on the measured container to achieve rapid installation and disassembly of the radar level meter through the connection between the connecting device and the radar level meter. However, this technical solution often requires welding the connecting device on the measured container, which is easy to cause damage to the measured container itself during the welding of the connecting device, and there is a risk of leakage of the measured substance in the container.

[0028] After long-term observation and experience summary, the inventor of this utility model provides a radar level meter and installation structure that can be quickly disassembled.
