[0002] Ultrasonic level gauges, instruments that accurately measure the height of liquids or solids using ultrasonic technology, play a crucial role in numerous fields due to their non-contact measurement, wide applicability to various media, and high accuracy. In industrial production, they are indispensable for monitoring the levels of storage tanks and reaction vessels in industries such as chemical, petroleum, and power. By monitoring liquid level information in real time, they ensure the stability and safety of production processes and prevent material spills or supply shortages. In urban water supply and sewage treatment systems, precise control of the levels in reservoirs and sedimentation tanks helps to rationally allocate water resources, efficiently treat sewage, and improve the operational efficiency of urban infrastructure. In agricultural irrigation, using ultrasonic level gauges to monitor irrigation water levels enables precise irrigation, avoids water waste, and contributes to water conservation in agriculture.

[0003] The existing technology has the following problems: Usually, ultrasonic level gauges are installed by fixing them to a bracket with bolts. This installation method is cumbersome and inconvenient. It not only increases the installation time, but also makes it difficult to adjust the height of the ultrasonic level gauge after installation, thus reducing its applicability.

[0004] Therefore, this utility model provides an installation structure for an ultrasonic level gauge to solve the above problems. Utility Model Content

[0005] This invention provides an installation structure for an ultrasonic level gauge, aiming to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: including two symmetrically distributed fixing rods and a quick-release structure mounted on top of the fixing rods, as well as an adjustment structure mounted on the outside of the fixing rods;

[0007] The quick-assembly structure includes a ring fixedly connected to one side of the top of the fixed rod and a toothed ring mounted above the ring, as well as three movable plates arranged in a circumferential array on the top of the ring. A toothed plate is fixedly connected to one side of each movable plate, and the toothed plate meshes with a gear that is rotatably connected to the top of the ring. A first spring is fixedly connected to the side of the movable plate near the inner wall of the ring. A first buffer rod is sleeved inside the first spring, and the end of the first spring away from the movable plate is fixedly connected to the inner wall of the ring.

[0008] As a preferred technical solution of this application, the gear meshes with the gear ring, and the top of the gear ring is fixedly connected to a movable ring that is slidably connected to the surface of the circular ring. The surface of the movable ring is provided with a through hole identical to that of the circular ring.

[0009] As a preferred technical solution of this application, the top of the ring is provided with a limiting groove for the sliding of the movable plate, and a fixed plate is fixedly connected to the end of the movable plate away from the first spring.

[0010] As a preferred technical solution of this application, two second springs are symmetrically distributed on the surface of the fixing plate, a second buffer rod is sleeved inside the second spring, and a rubber pad is fixedly connected to the end of the second spring away from the fixing plate.

[0011] As a preferred technical solution of this application, the adjustment structure includes a rectangular frame fixedly connected to the end of the fixed rod away from the ring and a support plate slidably connected inside the rectangular frame, and a third spring fixedly connected inside the rectangular frame. A limit post is fixedly connected to the end of the third spring near the support plate, and a pull rod is fixedly connected to the center of the end of the limit post connected to the third spring.

[0012] As a preferred technical solution of this application, the inner wall of the rectangular frame is provided with a circular groove for the third spring and the limiting post to move. The end of the third spring away from the limiting post is fixedly connected to the inner wall of the circular groove, and the end of the pull rod away from the limiting post passes through the circular groove to the outside of the rectangular frame.

[0013] As a preferred technical solution of this application, the surface of the support plate is provided with a plurality of limiting holes adapted to the limiting posts, and an mounting plate is fixedly connected to one side of the surface of the support plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] With its quick-installation structure, rotating the movable ring drives the gear ring to rotate. The gear ring meshes with the gear, causing the gear to rotate, which in turn drives the meshing gear plate to slide the movable plate along the limiting groove at the top of the ring. The first spring and the first buffer rod on one side of the movable plate provide elastic support, allowing the fixed plates on the three movable plates to automatically adjust the spacing according to the size of the level gauge. In conjunction with the rubber pads connected to the second spring and the second buffer rod on the surface of the fixed plate, it can firmly clamp level gauges of different specifications while avoiding equipment damage caused by hard contact. This device can be installed and fixed by simple rotation, significantly reducing labor and time costs, and is especially suitable for emergency repairs or rapid equipment replacement scenarios.

[0016] By adjusting the structure, pulling the lever compresses the third spring, causing the limiting post to disengage from the limiting hole on the support plate surface. At this point, the support plate can slide freely within the rectangular frame. After adjusting to the appropriate position, releasing the lever causes the limiting post to engage with the corresponding limiting hole under the elastic force of the third spring, thus fixing the support plate. This allows for convenient adjustment of the ultrasonic level gauge's height even after installation, improving the device's applicability. Attached Figure Description

Detailed Implementation

[0023] 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.

[0024] This utility model provides, for example Figure 1-5 The installation structure of an ultrasonic level gauge shown includes two symmetrically distributed fixing rods 1, a quick-release structure 2 mounted on top of the fixing rods 1, and an adjustment structure 3 mounted on the outside of the fixing rods 1.

[0025] The quick-assembly structure 2 includes a ring 201 fixedly connected to one side of the top of the fixed rod 1 and a toothed ring 202 mounted above the ring 201, as well as three movable plates 203 arranged in a circumferential array on the top of the ring 201. A toothed plate 204 is fixedly connected to one side of the movable plate 203. The toothed plate 204 meshes with a gear 205 that is rotatably connected to the top of the ring 201. A first spring 206 is fixedly connected to the side of the movable plate 203 near the inner wall of the ring 201. A first buffer rod is sleeved inside the first spring 206. The end of the first spring 206 away from the movable plate 203 is fixedly connected to the inner wall of the ring 201.

[0026] Using the above scheme, when the liquid level gauge is installed, rotating the movable ring 207 causes the bottom gear ring 202 to rotate synchronously. Since the gear ring 202 meshes with the gear 205, the gear 205 rotates accordingly and drives the meshing gear plate 204 to move. The gear plate 204 drives the movable plate 203 to slide smoothly along the limiting groove at the top of the circular ring 201. The first spring 206 and the first buffer rod on one side of the movable plate 203 are in a compressed or stretched state, providing a continuous elastic force to the movable plate 203, so that the three movable plates in a circular array... Plate 203 can automatically adjust its spacing according to the outer diameter of the level gauge. When the fixed plate 208 on the movable plate 203 contacts the surface of the level gauge, the second spring 209 and the second buffer rod symmetrically distributed on the surface of the fixed plate 208 will be further compressed, making flexible contact with the surface of the level gauge through the rubber pad 210. This dual elastic buffer design not only firmly clamps level gauges with different diameters, ensuring stability after installation, but also avoids wear on the outer shell or damage to internal components caused by hard collisions between metal parts and the level gauge, effectively protecting the equipment. The entire installation process does not require professional tools such as wrenches; it can be completed simply by rotating the movable ring 207. Single-person operation can quickly complete the installation or disassembly, significantly shortening the time for equipment replacement or maintenance and greatly improving response efficiency in emergency repair scenarios.

[0027] Gear 205 meshes with gear ring 202. A movable ring 207, which is slidably connected to the surface of ring 201, is fixedly connected to the top of gear ring 202. The surface of movable ring 207 has a through hole identical to that of ring 201. A limiting groove for sliding of movable plate 203 is provided on the top of ring 201. A fixed plate 208 is fixedly connected to the end of movable plate 203 away from the first spring 206. Two second springs 209 are symmetrically distributed on the surface of fixed plate 208. A second buffer rod is sleeved inside each second spring 209. A rubber pad 210 is fixedly connected to the end of the second spring 209 away from fixed plate 208. The adjusting structure 3 includes a rectangular frame 301 fixedly connected to the end of fixed rod 1 away from ring 201 and a slidably connected rectangular frame 301. The rectangular frame 301 has an internal support plate 302 and a third spring 303 fixedly connected inside the rectangular frame 301. A limit post 304 is fixedly connected to one end of the third spring 303 near the support plate 302. A pull rod 305 is fixedly connected to the center of the end of the limit post 304 connected to the third spring 303. A circular groove is provided on the inner wall of the rectangular frame 301 for the third spring 303 and the limit post 304 to move. The end of the third spring 303 away from the limit post 304 is fixedly connected to the inner wall of the circular groove. The end of the pull rod 305 away from the limit post 304 passes through the circular groove to the outside of the rectangular frame 301. A number of limit holes adapted to the limit post 304 are provided on the surface of the support plate 302. A mounting plate 306 is fixedly connected to one side of the surface of the support plate 302.

[0028] Using the above solution, when it is necessary to adjust the installation height or angle of the level gauge, pull the lever 305 on the outside of the rectangular frame 301. The lever 305 moves the limiting post 304 into the circular groove and compresses the third spring 303, causing the limiting post 304 to completely disengage from the limiting hole on the surface of the support plate 302. At this time, the support plate 302 can slide freely within the rectangular frame 301. After adjusting to the appropriate position according to the installation requirements, release the lever 305. The limiting post 304 pops out under the elastic force of the third spring 303 and re-engages into the corresponding limiting hole, thus firmly fixing the support plate 302. In this way, the height and angle of the mounting plate 306 can be flexibly adjusted.

[0029] The working principle of the installation structure of an ultrasonic level gauge according to an embodiment is as follows: The ultrasonic level gauge is placed at the center of the ring 201. The movable ring 207 is rotated. The movable ring 207 is fixedly connected to the top of the toothed ring 202 and slidably connected to the surface of the ring 201. Therefore, the toothed ring 202 will rotate synchronously. Since the toothed ring 202 meshes with the gear 205, the gear 205 rotates at the top of the ring 201, thereby driving the toothed plate 204 that meshes with it to move. The toothed plate 204 is fixedly connected to one side of the movable plate 203. Under the drive of the toothed plate 204, the movable plate 203 slides smoothly along the limiting groove at the top of the ring 201. At this time, the first spring 206 and the first buffer rod on the side of the movable plate 203 near the inner wall of the ring 201 are in a compressed state, providing a continuous elastic force to the movable plate 203, so that the spacing of the three movable plates 203 arranged in a circumferential array is automatically adjusted according to the outer diameter of the level gauge. As the movable plate 203 moves, the fixed plate 208 at the end of the movable plate 203 away from the first spring 206 gradually approaches the level gauge. The second spring 209 and the second buffer rod, symmetrically distributed on the surface of the fixed plate 208, will contact the surface of the level gauge and further compress it. Flexible contact with the surface of the level gauge is achieved through the rubber pad 210 until the level gauge is firmly clamped, completing the installation. If disassembly is required, the movable ring 207 is rotated in the opposite direction. Under the elastic force of the first spring 206, the movable plate 203 drives the fixed plate 208 to return to its original position, and the level gauge can be removed. The entire process does not require professional tools.

[0030] Next, adjust the installation position. When it is necessary to adjust the installation height or angle of the level gauge, pull the pull rod 305 on the outside of the rectangular frame 301. The pull rod 305 moves the limiting post 304 into the circular groove on the inner wall of the rectangular frame 301, while compressing the third spring 303, so that the limiting post 304 completely disengages from the limiting hole on the surface of the support plate 302. At this time, the support plate 302 can slide freely inside the rectangular frame 301 and be adjusted to a suitable position according to the installation requirements. After the adjustment is completed, release the pull rod 305. Under the elastic force of the third spring 303, the limiting post 304 pops out from the circular groove and re-engages into the corresponding limiting hole on the surface of the support plate 302, thus firmly fixing the support plate 302. By changing the position of the support plate 302 within the rectangular frame 301, the height and angle of the mounting plate 306 can be flexibly adjusted to adapt the mounting plate 306 to different installation scenarios, ensuring that the level gauge is in the optimal measurement position.

[0031] Finally, the entire structure is fixed to the designated installation location on the pipe, container, or other object using the mounting plate 306, completing the overall installation of the ultrasonic level gauge. If further adjustments are needed, simply repeat the above adjustment steps. If the level gauge needs to be replaced, repeat the installation or disassembly steps of quick-release structure 2.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
