Description

Technical Field

[0001] This utility model relates to the field of split-type radar wave level gauge technology, specifically a split-type radar wave level gauge. Background Technology

[0002] Radar level gauges are general-purpose radar level gauges. They are measuring instruments based on the time-of-flight principle. Radar waves travel at the speed of light, and the travel time can be converted into a level signal by electronic components. The probe emits high-frequency pulses that propagate in space at the speed of light. When the pulses encounter the material surface, they are reflected back and received by the receiver inside the instrument, which converts the distance signal into a level signal. In the current technology, split-type level gauges are also used, which refer to the instrument head and probe being installed separately and using connecting cables for signal transmission and reception. These are suitable for some specific applications.

[0003] Currently, probes are typically connected to flanges using bolts or welding. Bolt installation requires repeated rotation of the bolts, making replacement or repair extremely troublesome when the probe is damaged. This also hinders disassembly and reduces the practicality of the device. Therefore, we propose a split-type radar wave level gauge. Utility Model Content

[0004] The purpose of this utility model is to provide a split-type radar wave level gauge to solve the problem that in the current technology, the probe is usually connected to the flange by bolts or welding during installation. When the probe is damaged, replacement or repair is very troublesome, not conducive to disassembly, and reduces the practicality of the device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a split-type radar wave level gauge, including a flange, a connecting mechanism is provided inside the flange, a probe is connected through the bottom of the flange via the connecting mechanism, and a limit mechanism is provided at the top of the flange;

[0006] The connecting mechanism includes a positioning cavity located in the middle of the bottom of the flange, an installation cavity inside the flange, a moving groove symmetrically extending through the top of the installation cavity, a connecting rod sliding inside the moving groove, a plug fixed at the bottom end of the connecting rod, a turntable rotating on the top of the flange, a spiral groove symmetrically formed at the center of the top of the turntable, a connecting plate fixed to the outside of the probe, and slots symmetrically formed on the outside of the connecting plate.

[0007] Preferably, the connecting mechanism further includes positioning holes symmetrically opened at the top of the positioning cavity, a limit groove opened at the top of the flange, sliding rods symmetrically fixed on the side wall of the mounting cavity, a through hole opened on one side of the insert block, a limit block symmetrically fixed at the bottom of the turntable, and a positioning rod symmetrically fixed at the top of the connecting plate.

[0008] Preferably, the limiting block is located inside the limiting groove to limit the turntable so that the turntable can only rotate, and the connecting rod is located inside the spiral groove so that the spiral groove rotates when the turntable rotates, causing the connecting rod to move.

[0009] Preferably, the diameter of the connecting plate is equal to the diameter of the positioning cavity to ensure a stable connection, and a sealing gasket is fixed to the top of the connecting plate to ensure a tight seal.

[0010] Preferably, the slide bar is located inside the through hole, that is, the insert block slides on the outside of the slide bar to limit the insertion block and make the insertion block slide stably, and the insertion block penetrates the side wall of the positioning cavity.

[0011] Preferably, the limiting mechanism includes an insertion hole opened on the outside of the turntable, a mounting plate fixed to the top edge of the flange, a rod symmetrically sliding through one side of the mounting plate, a circular plate fixed to the outside of the rod, a pull plate fixed to one end of the rod, and a return spring sleeved on the outside of the rod.

[0012] Preferably, the two ends of the return spring are fixedly connected to the opposite sides of the mounting plate and the circular plate, respectively, to facilitate the reset of the insertion rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This application utilizes a connecting mechanism. During replacement, the turntable is rotated counterclockwise, causing the spiral groove to rotate. This causes the connecting rod to move inside the spiral groove, gradually moving the connecting rod towards the end of the spiral groove. This causes the two connecting rods to move away from each other, which in turn causes the insert blocks to move away from each other, thus removing the insert blocks from the slots. The connecting plate is then disassembled, and a new probe is installed. The connecting plate is then embedded in the positioning cavity, and the turntable is rotated clockwise to embed the insert blocks into the slots, completing the fixation. This avoids the use of bolts or welding for connection, making disassembly and assembly simpler and more convenient, saving time and effort, facilitating maintenance and replacement, and improving the convenience of the device.

[0015] 2. In this application, a limiting mechanism is used. By pulling the pull plate, the insertion rod moves, and at the same time, the circular plate moves, compressing the return spring. After the turntable deflects, the pull plate is loosened, allowing the insertion rod to fit against the outside of the turntable. After replacement, the turntable resets, and the insertion rod is reset by the continued reset of the return spring, thus embedding the insertion rod into the insertion hole and fixing the turntable. This prevents the turntable from deflecting after installation, ensuring the stability of the connection and preventing loosening. Attached Figure Description

Detailed Implementation

[0022] 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.

[0023] Example: Figures 1-5As shown, this utility model provides a technical solution for a split-type radar wave level gauge, including a flange 100, a connecting mechanism 300 inside the flange 100, a radar level gauge probe 200 being connected through the connecting mechanism 300 to the bottom of the flange 100, and a limiting mechanism 400 being provided at the top of the flange 100.

[0024] Please see Figure 2 , Figure 3 and Figure 4 The connecting mechanism 300 includes a positioning cavity 310 located at the center of the bottom of the flange 100, an installation cavity 320 inside the flange 100, a symmetrical moving groove 330 extending through the top of the installation cavity 320, a connecting rod 340 sliding inside the moving groove 330, a plug block 350 fixed at the bottom end of the connecting rod 340, a turntable 360 ​​rotating on the top of the flange 100, a spiral groove 370 symmetrically formed at the center of the top of the turntable 360, and a connecting plate 380 fixed to the outside of the radar level gauge probe 200. The outer side of the 0 is symmetrically provided with slots 390; the connecting mechanism 300 also includes positioning holes 311 symmetrically provided on the top of the positioning cavity 310, a limiting groove 312 provided on the top of the flange 100, slide rods 321 symmetrically fixed on the side wall of the mounting cavity 320, a through hole 351 provided through one side of the insert block 350, a limiting block 361 symmetrically fixed on the bottom of the turntable 360, and a positioning rod 381 symmetrically fixed on the top of the connecting plate 380; the limiting block 361 is located inside the limiting groove 312, and the connecting rod 340 is located inside the spiral groove 370. The diameter of the connecting plate 380 is equal to the diameter of the positioning cavity 310, and a sealing gasket is fixed on the top of the connecting plate 380; the slide rod 321 is located inside the through hole 351, that is, the insert block 350 slides on the outside of the slide rod 321, and the insert block 350 penetrates the side wall of the positioning cavity 310; by utilizing the setting of the connecting mechanism 300, when replacing, by rotating the turntable 360 ​​counterclockwise, the spiral groove 370 is rotated, thereby causing the connecting rod 340 to move inside the spiral groove 370, so that the connecting rod 340 gradually moves towards the end of the spiral groove 370. The movement of the part causes the two connecting rods 340 to move away from each other, which in turn causes the insert blocks 350 to move away from each other, thus moving the insert blocks 350 out of the slot 390. The connecting plate 380 is then disassembled, and the new radar level gauge probe 200 is installed, so that the connecting plate 380 is embedded in the positioning cavity 310. The turntable 360 ​​is rotated clockwise, so that the insert blocks 350 are embedded in the slot 390, completing the fixation. This avoids the use of bolts or welding for connection, making disassembly and assembly simpler and more convenient, saving time and effort, facilitating maintenance and replacement, and improving the convenience of the device.

[0025] Please see Figure 4 and Figure 5The limiting mechanism 400 includes an insertion hole 410 on the outside of the turntable 360. A mounting plate 420 is fixed to the top edge of the flange 100. A rod 430 slides symmetrically through one side of the mounting plate 420. A circular plate 440 is fixed to the outside of the rod 430. A pull plate 450 is fixed to one end of the rod 430. A return spring 460 is sleeved on the outside of the rod 430. Both ends of the return spring 460 are fixedly connected to the opposite sides of the mounting plate 420 and the circular plate 440, respectively. Using the limiting mechanism 400, the pull plate 450... The movable pull plate 450 moves the insertion rod 430 and simultaneously moves the circular plate 440, compressing the return spring 460. After the turntable 360 ​​deflects, the pull plate 450 is loosened, allowing the insertion rod 430 to fit against the outer side of the turntable 360. After replacement, the turntable 360 ​​resets, and the return spring 460 continues to reset, causing the insertion rod 430 to reset as well. This allows the insertion rod 430 to be embedded in the insertion hole 410, fixing the turntable 360 ​​in place and preventing it from deflecting after installation, thus ensuring the stability of the connection and preventing loosening.

[0026] In use, the radar level gauge probe 200 is connected to the level gauge head via a connecting cable. When the radar level gauge probe 200 is damaged or requires maintenance, and needs replacement, first pull the pull plate 450, moving the insertion rod 430 and simultaneously moving the circular plate 440, thus pressing the return spring 460. This causes the insertion rod 430 to move out of the insertion hole 410, releasing the fixation on the turntable 360. Then, rotate the turntable 360 ​​counterclockwise. Loosening the pull plate 450, the reset spring 460 causes the end of the insertion rod 430 to adhere to the outer side of the turntable 360, while the insertion rod 430 separates from the insertion hole 410, thus failing to limit the turntable 360. Continuing to rotate the turntable 360 ​​causes it to deflect 180 degrees, rotating the spiral groove 370. This causes the connecting rod 340 to move within the spiral groove 370, gradually moving it towards the end of the spiral groove 370. This allows the two connecting rods 340 to move within the moving groove 3... The internal components of slide 30 move away from each other, causing the insert blocks 350 to move away from each other as well. This allows the insert blocks 350 to slide outside the slide bar 321, thus moving them out of the slot 390. This releases the fixing of the connecting plate 380, allowing it to be disassembled. The radar level gauge probe 200 is then removed, and a new radar level gauge probe 200 is installed. The connecting plate 380 is then embedded in the positioning cavity 310. The positioning rod 381 is inserted into the positioning hole 311, and the turntable 360 ​​is rotated clockwise. This causes the spiral groove 370 to rotate, causing the connecting rod 340 to drive the insert blocks 350 closer together, so that the insert blocks 350 are embedded in the slot 390, fixing the connecting plate 380. When the turntable 360 ​​rotates to its original position, the insert rod 430 aligns with the insertion hole 410. At this time, the return spring 460 continues to return to its original position, driving the circular plate 440 to move, so that the insert rod 430 is embedded in the insertion hole 410, fixing the turntable 360 ​​and preventing the turntable 360 ​​from deflecting after installation, thus completing the fixing.
