Description

Technical Field

[0001] This utility model relates to the technical field of radar level gauges, specifically a radar level gauge that avoids deformation under pressure. Background Technology

[0002] Radar level gauges are non-contact measuring instruments that detect the height of materials in a container by emitting electromagnetic waves and receiving their reflected signals. Their main function is to measure the level of liquids, solids and other media in a non-contact and continuous manner, and they are widely used.

[0003] As disclosed in CN219104113U, a radar level gauge that is easy to install and remove relates to the field of radar level gauge technology. It includes a radar level gauge body, a cable interface fixedly installed on the side of the radar level gauge body, a flange fixedly connected to the lower end of the radar level gauge body, a horn antenna fixedly installed at the lower end of the radar level gauge body, a guide rail fixedly connected to the side of the radar level gauge body, and a magnetic sheet fixedly installed on the surface of the guide rail. An arc plate is provided at the upper end of the flange. Using the magnetic strip and magnetic sheet, the arc plate can be attracted to the guide rail, allowing the arc plate to move along the guide rail. A positioning rod passes through the through hole of the flange. Thus, when installing the radar level gauge, only the positioning rod is needed to connect the flange to the flange on the object being installed to initially fix the radar level gauge. No human intervention is required to lift the radar level gauge, making installation and disassembly simple; only one person is needed to operate it.

[0004] However, existing technologies have problems such as poor fastening of radar level gauge installation and positioning, and the radar level gauge is directly exposed to the outside during use without any protective measures, making it susceptible to damage from the pressure of external objects and affecting its service life. For example, the comparative patents listed above have this problem.

[0005] To address this issue, we propose a radar level gauge that avoids deformation under pressure. Utility Model Content

[0006] The purpose of this invention is to provide a radar level gauge that avoids deformation under pressure, thereby solving the problems mentioned in the background art, such as poor tightness of radar level gauge installation and positioning, and the fact that radar level gauges are directly exposed to the outside during use without any protective measures, making them susceptible to damage from external pressure and affecting their service life.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a radar level gauge that avoids deformation under pressure, comprising a radar level gauge body, a cable interface, a connecting line, and a flange;

[0008] Also includes:

[0009] The mounting components are symmetrically arranged on the front and rear sides of the upper end of the flange. The mounting components are used to fix the radar level gauge body on the flange. The mounting components include auxiliary blocks fixed on the front and rear sides of the upper end of the flange, a movable connecting plate telescopically connected in the middle of the auxiliary blocks, a fixed connecting sleeve fixed on the inner side of the movable connecting plate, a fixed connecting rod fixed on the outer side of the auxiliary blocks, and a fixed connecting cap for locking and limiting.

[0010] The outer cover of the radar level gauge body is equipped with a safety shield, and the lower end of the safety shield is provided with a buffer component at an equal angle.

[0011] Preferably, the upper end of the radar level gauge body is provided with a cable interface, and the lower end of the radar level gauge body is connected with a connecting line. At the same time, the front and rear ends of the lower end of the radar level gauge body are fixedly connected with fixing protrusions for positioning.

[0012] Preferably, the radar level gauge body drive connection line is inserted into the middle of the flange.

[0013] Preferably, the movable connecting plate drives the fixed connecting sleeve to move back and forth on the upper end of the flange, and the fixed connecting sleeve is fitted on the outside of the fixed protrusion, and the fixed connecting sleeve is fitted to the front and rear ends of the radar level gauge body.

[0014] Preferably, a fixed connecting rod is provided through the end of the fixed connecting sleeve away from the radar level gauge body, and a fixed connecting cap is threaded to the outside of the fixed connecting rod, while the fixed connecting cap is fitted to the outside of the movable connecting plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the radar level gauge that avoids deformation under pressure can be installed and positioned on the flange very quickly and stably through the setting of the installation components. Combined with the safety guard set on the outside of the radar level gauge body, it can protect the radar level gauge body. At the same time, when subjected to external pressure, the lower end of the safety guard is provided with a buffer component. The setting of the buffer component can prevent deformation caused by external pressure, further improving the actual protection effect.

[0018] 1. An installation assembly is provided, which is symmetrically arranged on the front and rear sides of the upper end of the flange. The installation assembly includes an auxiliary block, a movable connecting plate, a fixed connecting sleeve, a fixed connecting rod, and a fixed connecting cap.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-7 The present invention provides the following technical solution:

[0031] To address the problems of poor fastening of existing radar level gauge installation and positioning, and the fact that radar level gauges are directly exposed to the outside without any protective measures during use, making them susceptible to damage from external pressure and affecting their service life, this solution provides a radar level gauge that avoids deformation under pressure. The gauge comprises a radar level gauge body 1, a cable interface 2, a connecting line 3, and a flange 5. Mounting components are symmetrically arranged on the front and rear sides of the upper end of the flange 5. These components are used to fix the radar level gauge body 1 onto the flange 5. A safety guard 11 is provided on the outer side of the radar level gauge body 1, and buffer components are provided at equal angles at the lower end of the safety guard 11.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a cable interface 2 is provided at the upper end of the radar level gauge body 1, and a connecting line 3 is provided at the lower end of the radar level gauge body 1. First, the radar level gauge body 1, along with the connecting line 3, is inserted into the middle of the flange 5. At the same time, the radar level gauge body 1 is placed on the upper end of the flange 5 and in the middle of the safety guard 11. Then, the mounting components symmetrically arranged on the front and rear sides of the upper end of the flange 5 are used. The mounting components include auxiliary blocks 6 fixed on the front and rear sides of the upper end of the flange 5, a movable connecting plate 7 telescopically connected to the middle of the auxiliary block 6, a fixed connecting sleeve 8 fixed inside the movable connecting plate 7, a fixed connecting rod 9 fixed outside the auxiliary block 6, and a locking limit device. With the fixed connecting cap 10 in place, align the fixed protrusion 4 with the fixed connecting sleeve 8, and then move the movable connecting plate 7. The movable connecting plate 7 slides between itself and the auxiliary block 6, and simultaneously slides between itself and the fixed connecting rod 9. The movable connecting plate 7 drives the fixed connecting sleeve 8 to be fitted onto the outside of the fixed protrusion 4, thereby facilitating the fixed installation of the radar level gauge body 1 onto the flange 5. Then, rotate the fixed connecting cap 10, which is threaded onto the outer surface of the fixed connecting rod 9, so that the fixed connecting cap 10 fits against the outside of the movable connecting plate 7, thereby limiting the fixed connecting sleeve 8. In addition, the radar level gauge body 1 can be disassembled, maintained, and replaced by reversing the above operations.

[0033] A safety cover 11 is installed on the outside of the radar level gauge body 1. The safety cover 11 prevents the radar level gauge body 1 from being directly exposed, providing excellent protection. Furthermore, a buffer component is provided at the lower end of the safety cover 11. Figure 1 , Figure 6 and Figure 7 As shown, the buffer assembly includes a buffer rod 12 fixed to the lower end of the safety guard 11, a buffer cylinder 13 fixedly connected to the upper end of the flange 5, and a buffer spring 14 disposed between the buffer rod 12 and the buffer cylinder 13. When squeezed by an external object, the safety guard 11 moves downward, causing the buffer rod 12 and the buffer cylinder 13 to slide and extend. At the same time, the buffer rod 12 squeezes the buffer spring 14, causing the buffer spring 14 to undergo elastic deformation, which can play a good buffering and protection role, avoiding direct squeezing and deformation of the radar level gauge body 1.

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