Description

Technical Field

[0001] The utility model relates to the technical field of radar liquid level measurement, in particular to a radar liquid level measurement device. Background Art

[0002] Radar level meter is a general radar level meter. It is a measuring instrument based on the time travel principle. Radar waves run at the speed of light. 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 transmits very short microwave pulses with very low energy and is transmitted and received through the antenna system. In the current existing technology, when measuring the liquid in the equipment body, the radar level measuring device is placed on the top of the equipment body, and the detection rod and the radar are designed as an integrated whole. The detection rod extends to the inside of the equipment body to transmit pulses. This operation is convenient and fast, and can ensure the structural integrity. However, there are often many corrosive gases in the chemical industry, which causes the radar wave liquid level detection equipment to be corroded, resulting in the staff frequently inspecting the radar wave liquid level detection setting, which increases the staff's inspection frequency and reduces the service life of the radar detector.

[0004] Therefore, it is particularly important to improve the existing radar liquid level measurement equipment, design a new radar liquid level measurement equipment to solve the above technical defects, and improve the practicality of the overall radar liquid level measurement equipment.

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] Example:

[0024] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0025] A radar liquid level measuring device comprises a device body 1, a receiver 2 is installed on the top of the device body 1, a connection plate 3 is installed outside the receiver 2, a connecting rod 4 is installed at the bottom of the connecting plate 3, a detection rod 5 is installed inside the connecting rod 4, a sliding sleeve 6 is installed outside the side of the connecting rod 4 close to the detection rod 5, and a quick release component 7 is installed inside the sliding sleeve 6.

[0026] The quick-release assembly 7 is used for quick installation between the connecting rod 4 and the detection rod 5 .

[0027] For further information, see Figure 2 and Figure 3In this embodiment, the quick-release assembly 7 includes a first spring 701, an extrusion block 702, a first through groove 703, a second through groove 704 and a ball 705. The first spring 701 is sleeved on the outside of the connecting rod 4, the extrusion block 702 is installed in the interior of the sliding sleeve 6, the first through groove 703 is opened in the interior of the connecting rod 4, the second through groove 704 is opened in the interior of the detection rod 5, and the ball 705 is installed in the interior of the first through groove 703. When the detection rod 5 is corroded and needs to be replaced, the sliding sleeve 6 is slid upward to drive the first spring 701 to contract, so that the extrusion block 702 is separated from the first through groove 703, so that the ball 705 slides from the inside of the second through groove 704 to the inside of the first through groove 703, thereby separating the connecting rod 4 and the detection rod 5, so that the detection rod 5 is replaced.

[0028] Among them, see Figure 2 and Figure 3 In this embodiment, a groove 706 is provided inside the sliding sleeve 6, and the first spring 701 is slidably connected to the connecting rod 4 through the groove 706. The expansion and contraction size of the first spring 701 is limited by the groove 706, and the groove 706 cooperates with the first spring 701 to achieve the reset work after the sliding sleeve 6 moves upward.

[0029] Second, see Figure 3 In the present embodiment, the outer diameter of the first through groove 703 is larger than the inner diameter, the second through groove 704 is designed in a trumpet-shaped structure, and the interiors of the first through groove 703 and the second through groove 704 are interconnected. The trumpet-shaped second through groove 704 prevents the ball 705 from completely escaping from the interior of the second through groove 704. The outer diameter of the first through groove 703 is larger than the inner diameter, which will also cause the ball 705 to fall out of the interior of the first through groove 703.

[0030] Furthermore, please see Figure 3 In this embodiment, a T-slot 401 is provided inside the connecting rod 4, a T-block 501 is installed at the top of the detecting rod 5 at a position corresponding to the T-slot 401, and a stopper 707 is installed at the bottom end of the sliding sleeve 6. The T-block 501 is inserted into the T-slot 401 to increase the contact area between the two, thereby improving the sealing performance. The ball 705 is fixed inside the first through groove 703 by the stopper 707 to prevent the ball 705 from falling.

[0031] For further information, see Figure 1 , Figure 2 and Figure 4In this embodiment, a hexagonal column 8 is installed on the top of the connecting plate 3, and a main rod 9 is installed at the bottom of the hexagonal column 8. A circular hole is opened at the bottom end of the main rod 9, and a squeezing ball 10 is installed inside the circular hole. A spherical groove is opened at a position corresponding to the squeezing ball 10 inside the device body 1. The squeezing ball 10 is pushed into the inside of the spherical groove, so that the main rod 9 is connected to the top of the device body 1, ensuring that the receiver 2 is stably installed on the top of the device body 1.

[0032] For further information, see Figure 1 , Figure 2 and Figure 4 In this embodiment, a twist knob 801 is installed on the top of the hexagonal column 8, a threaded rod 11 is installed at the bottom of the twist knob 801 and inside the main rod 9, a second spring 12 is installed at the bottom of the threaded rod 11, and an extrusion rod 13 is installed at the bottom of the second spring 12. By rotating the twist knob 801, the threaded rod 11 is threadedly moved inside the main rod 9, so that the threaded rod 11 squeezes the second spring 12, and at the same time drives the extrusion rod 13 to move downward, pushing the extrusion ball 10 into the spherical groove, completing the quick connection between the receiver 2 and the device body 1.

[0033] In this embodiment, the implementation scenario is specifically as follows: in actual use, by inserting the main rod 9 into the connecting disk 3 and extending it to the inside of the device body 1, by turning the knob 801, the threaded rod 11 is threadedly moved inside the main rod 9, so that the threaded rod 11 squeezes the second spring 12, and at the same time drives the squeezing rod 13 to move downward, pushing the squeezing ball 10 into the spherical groove, completing the quick connection between the receiver 2 and the device body 1. When the detection rod 5 is corroded and needs to be replaced, the sliding sleeve 6 is slid upward to drive the first spring 701 to contract, so that the squeezing block 702 is separated from the first through groove 703, so that the ball 705 slides from the inside of the second through groove 704 to the inside of the first through groove 703, thereby separating the connecting rod 4 and the detection rod 5, so that the detection rod 5 is replaced.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
