Description

Technical Field

[0001] This utility model relates to the technical field of liquid level gauge installation, and in particular to a liquid level gauge that is easy to install. Background Technology

[0002] A level gauge is an instrument used to measure the position of a liquid surface. It is widely used in various industrial fields, such as water treatment, chemical, petroleum, pharmaceutical, and food industries. Some larger water tanks use radar or ultrasonic level gauges. Ultrasonic level gauges are similar to radar level gauges, but use ultrasound instead of microwaves. The ultrasonic sensor emits ultrasonic pulses, which are reflected back after encountering the liquid surface. The liquid level is calculated by measuring the time difference.

[0003] In the existing technology, when installing an ultrasonic level gauge, a hole is pre-drilled in the top of the water tank to insert the probe of the ultrasonic level gauge into the water tank. Then, the ultrasonic level gauge is fixed to the mounting hole in the top of the water tank by two flanges, thus achieving the effect of installing the ultrasonic level gauge. However, when installing through flanges, the two flanges need to be fixed with bolts, which requires tightening all the bolts one by one, thus consuming a lot of time and affecting the installation efficiency of the ultrasonic level gauge. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a liquid level gauge that is easy to install, so as to solve the technical problems mentioned in the background art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] An easy-to-install level gauge includes an outer positioning plate and a level gauge body. The bottom of the outer positioning plate is connected to an annular mesh frame, and the bottom side of the annular mesh frame is connected to an inner positioning plate. A number of inner positioning components are provided on the outer periphery of the inner positioning plate. The measuring end of the level gauge body passes through the outer positioning plate and the inner positioning plate and extends to the bottom of the inner positioning plate.

[0007] The inner positioning component includes a cavity, a slider, a slot, a support block, and a through hole. The slot is located on the outer periphery of the inner positioning disk. The slider is slidably installed in the cavity and is dynamically sealed within the cavity. The slot is located on the top side of the slider. The support block is slidably installed in the slot and is dynamically sealed within the slot. The through hole is located on the side of the slider near the center of the inner positioning disk. A hydraulic component is provided on the top of the outer positioning disk.

[0008] In a preferred embodiment, the present invention can be further configured such that: a rubber cover is connected between the inner positioning disk and the outer positioning disk, the rubber cover is sleeved on the outside of the annular mesh frame, and the bottom and top sidewalls of the inner sidewall of the rubber cover are respectively connected to the bottom and top sides of the annular mesh frame.

[0009] In a preferred embodiment, the present invention can be further configured as follows: the hydraulic component includes a driving part and a conveying part; the driving part includes an annular cavity; the annular cavity is opened inside the outer positioning disk; a rotating ring is provided on the top side of the outer positioning disk; the bottom side of the rotating ring extends into the annular cavity; the rotating ring is threadedly connected to the top sidewall of the annular cavity; an annular disk is connected to the bottom side of the rotating ring; and the annular disk is dynamically sealed inside the annular cavity.

[0010] In a preferred embodiment, the present invention can be further configured such that: the conveying part includes a sealing tube, the sealing tube is connected to the bottom side of the outer positioning plate, and the bottom end of the sealing tube extends into the rubber cover.

[0011] In a preferred embodiment, the present invention can be further configured such that: a hydraulic pipe is connected to the bottom side of the rubber cover, the bottom end of the hydraulic pipe extends downward into the inner positioning plate, and the bottom end of the hydraulic pipe communicates with the cavity groove.

[0012] In a preferred embodiment, the present invention can be further configured such that: the side of the slider away from the center of the inner positioning disk is arc-shaped, the arc-shaped side of the slider has the same curvature as the outer periphery of the inner positioning disk, and the arc-shaped side of the slider is aligned with the outer periphery of the inner positioning disk.

[0013] In summary, this utility model has at least one of the following beneficial technical effects:

[0014] 1. This easy-to-install level gauge, when in use, has its bottom side of the outer positioning plate attached to the top side of the water tank, and its measuring head inserted into the pre-made hole in the water tank. The inner positioning component is positioned by hydraulic components, which achieves the effect of quickly installing the level gauge and thus improves the efficiency of level gauge installation.

[0015] 2. The easy-to-install level gauge has a rubber cover fitted on the outside of the annular mesh frame, and the inner bottom side wall and top side wall of the rubber cover are connected to the top side wall and bottom side wall of the annular mesh frame, respectively. Thus, when the inner positioning plate is inserted into the water tank, the rubber cover can seal the preset hole to prevent external dust and rainwater from entering.

[0016] 3. This easy-to-install level gauge has an annular cavity initially filled with hydraulic oil. After inserting the inner positioning plate into the water tank and ensuring that the bottom side of the outer positioning plate is in contact with the top side of the water tank, rotating the rotating ring will cause the annular plate to move downwards into the annular cavity, thereby pushing the hydraulic oil and driving the hydraulic components.

[0017] 4. This easy-to-install level gauge allows hydraulic oil to enter the sealed tube when squeezed. After the level gauge body is positioned, the hydraulic oil increases in the rubber cover when the rotating ring is rotated, causing the rubber cover to expand. This allows the outer periphery of the rubber cover to fit against the inner periphery of the pre-drilled hole in the water tank, further improving the sealing performance of the pre-drilled hole in the water tank after the level gauge is installed.

[0018] 5. This easy-to-install level gauge has a hydraulic pipe that connects to a rubber cover and a cavity. The hydraulic oil passes through the rubber cover and then enters the cavity through the hydraulic pipe, thereby pushing the slider and ultimately causing the support block to fit against the top side wall of the water tank, enabling the level gauge to be installed quickly.

Detailed Implementation

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] Example:

[0026] Reference Figures 1-3 The present invention discloses an easy-to-install liquid level gauge, comprising an outer positioning plate 1 and a liquid level gauge body 2. The bottom of the outer positioning plate 1 is connected to an annular mesh frame 3, and the bottom side of the annular mesh frame 3 is connected to an inner positioning plate 4. A plurality of inner positioning components 5 are provided on the outer periphery of the inner positioning plate 4. The measuring end of the liquid level gauge body 2 passes through the outer positioning plate 1 and the inner positioning plate 4 and extends to the bottom of the inner positioning plate 4.

[0027] The inner positioning component 5 includes a cavity 6, a slider 7, a slot 8, a support block 9, and a through hole 10. The slot 8 is located on the outer periphery of the inner positioning disk 4. The slider 7 is slidably installed in the cavity 6 and is dynamically sealed within the cavity 6. The slot 8 is located on the top side of the slider 7. The support block 9 is slidably installed in the slot 8 and is dynamically sealed within the slot 8. The through hole 10 is located on the side of the slider 7 near the center of the inner positioning disk 4. A hydraulic component 11 is provided on the top of the outer positioning disk 1.

[0028] In this embodiment, when in use, the measuring end of the level gauge 2 is inserted into the corresponding hole in the water tank. Then, the hydraulic component 11 drives the slider 7 in the cavity 6 to slide. The hydraulic oil in the hydraulic component 11 is injected into the empty groove 8 through the perforation 10. After the gap at the bottom of the empty groove 8 is filled, the slider 7 will be pushed to slide in the empty groove 8. The cross section of the slider 7 near the center of the inner positioning ring is I-shaped, so as to prevent the slider 7 from being completely pushed out of the cavity 6. After the slider 7 is pushed to the designated position, the support block 9 is exposed. As the hydraulic pressure in the cavity 6 increases, the support block 9 will be pushed to move upward in the empty groove 8. Finally, the top side of the support block 9 will abut against the top side wall of the water tank.

[0029] In addition, when the top side of the support block 9 abuts against the bottom side wall of the water tank, the slider 7 will be subjected to the force of the support block 9, which will pull the annular mesh frame 3 and the outer positioning plate 1 downward, so that the positioning plate fits against the top side wall of the water tank, thereby achieving the movement of the outer positioning plate 1 and the support block 9 to clamp and fix the top side wall of the water tank, which can achieve the effect of quick installation.

[0030] In a further preferred embodiment of this utility model, such as Figure 2 As shown, a rubber cover 12 is connected between the inner positioning disk 4 and the outer positioning disk 1. The rubber cover 12 is sleeved on the outside of the annular mesh frame 3, and the bottom and top side walls of the rubber cover 12 are connected to the bottom and top sides of the annular mesh frame 3, respectively.

[0031] In this embodiment, the rubber cover 12 is fitted onto the outside of the annular mesh frame 3, and the inner bottom sidewall and top sidewall of the rubber cover 12 are connected to the top sidewall and bottom sidewall of the annular mesh frame 3, respectively. Thus, when the inner positioning plate 4 is inserted into the water tank, the rubber cover 12 can seal the preset hole to prevent external dust and rainwater from entering.

[0032] In a further preferred embodiment of this utility model, such as Figure 2 As shown, the hydraulic component 11 includes a driving part and a conveying part. The driving part includes an annular cavity 13, which is opened inside the outer positioning disk 1. A rotating ring 14 is provided on the top side of the outer positioning disk 1, and the bottom side of the rotating ring 14 extends into the annular cavity 13. The rotating ring 14 is threadedly connected to the top sidewall of the annular cavity 13. An annular disk 15 is connected to the bottom side of the rotating ring 14, and the annular disk 15 is dynamically sealed inside the annular cavity 13.

[0033] In this embodiment, the annular cavity 13 is initially filled with hydraulic oil. After the inner positioning plate 4 is inserted into the water tank and the bottom side of the outer positioning plate 1 is attached to the top side of the water tank, the rotating ring 14 is rotated. The rotating ring 14 will drive the annular plate 15 to move downward in the annular cavity 13, thereby pushing the hydraulic oil and driving it in the hydraulic component 11.

[0034] In a further preferred embodiment of this utility model, such as Figure 2 As shown, the conveying part includes a sealing tube 16, which is connected to the bottom side of the outer positioning plate 1, and the bottom end of the sealing tube 16 extends into the rubber cover 12.

[0035] In this embodiment, when the hydraulic oil is squeezed, it will enter the sealing tube 16. After the level gauge body 2 is positioned, the hydraulic oil will increase in the rubber cover 12 when the rotating ring 14 is rotated. This will cause the rubber cover 12 to expand, so that the outer peripheral side of the rubber cover 12 fits with the inner peripheral side of the preset hole in the water tank, further improving the sealing performance of the pre-made hole in the water tank after the level gauge is installed.

[0036] In a further preferred embodiment of this utility model, such as Figure 2-3 As shown, a hydraulic pipe 17 is connected to the bottom side of the rubber cover 12. The bottom end of the hydraulic pipe 17 extends downward into the inner positioning plate 4, and the bottom end of the hydraulic pipe 17 communicates with the cavity 6.

[0037] In this embodiment, the hydraulic pipe 17 is connected to the rubber cover 12 and the cavity 6. The hydraulic oil passes through the rubber cover 12 and then enters the cavity 6 through the hydraulic pipe 17, thereby pushing the slider 7. Ultimately, it can drive the support block 9 to fit against the top side wall of the water tank, enabling the level gauge to be installed quickly.

[0038] In a further preferred embodiment of this utility model, such as Figure 2 As shown, the side of the slider 7 away from the center of the inner positioning disk 4 is arc-shaped, and the arc-shaped side of the slider 7 has the same curvature as the outer periphery of the inner positioning disk 4. The arc-shaped side of the slider 7 is aligned with the outer periphery of the inner positioning disk 4.

[0039] In this embodiment, the side of the slider 7 furthest from the center of the inner positioning disk 4 is arc-shaped, and its curvature is the same as that of the outer periphery of the inner positioning disk 4. This avoids the slider 7 from being scratched when inserted into the water tank, thus preventing wear on the slider 7 and avoiding affecting the subsequent installation and positioning of the level gauge.

[0040] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
