Description

Technical Field

[0001] This utility model generally relates to the field of marine technology, and specifically to a liquid tank level monitoring device. Background Technology

[0002] Shipboard liquid tanks are typically equipped with liquid level monitoring devices to monitor and obtain liquid level data within the tank. Existing liquid level monitoring devices usually consist of a sleeve and an immersion-type liquid level sensor. The liquid level sensor includes a probe and a cable connected to the probe. The sleeve is installed inside the liquid tank, with its top end extending through the top wall of the tank. The probe is installed from the top opening of the sleeve to the bottom. To reduce probe movement within the sleeve, a locating ring is usually screwed onto the outer circumference of the probe.

[0003] However, the liquid level sensors mentioned above are currently purchased by shipyards from the market, and the probes of liquid level sensors on the market are usually not equipped with threaded connection holes. This means that shipyard personnel need to drill threaded holes on the probes, which not only increases the difficulty of the operation, but also increases the risk of probe damage. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a liquid tank level monitoring device.

[0005] This application provides a liquid tank level monitoring device, comprising:

[0006] A liquid level sensor, which includes a connected probe and cable;

[0007] The positioning structure includes a first positioning frame and a second positioning frame. The second positioning frame is detachably fixed to one side of the first positioning frame. A cable bundler is provided in the middle of the first positioning frame, through which the cable passes. The second positioning frame is provided with a positioning tube, which is sleeved on the outer periphery of the probe and cooperates with the probe positioning.

[0008] Furthermore, the first positioning frame includes a positioning ring and a plurality of first connecting rods. The cable bundler is located in the middle of the positioning ring, and the plurality of first connecting rods are located between the cable bundler and the positioning ring and are spaced apart circumferentially around the cable bundler. The two ends of the first connecting rods are respectively connected to the cable bundler and the positioning ring.

[0009] Furthermore, the second positioning frame includes a plurality of second connecting rods, which are spaced apart circumferentially around the positioning tube, wherein the two ends of the second connecting rods are respectively connected to the positioning tube and the positioning ring.

[0010] Furthermore, the second connecting rod is set at an angle.

[0011] Furthermore, the cable bundler and the positioning tube are coaxially arranged.

[0012] Furthermore, the first positioning frame and the second positioning frame are screwed together.

[0013] Furthermore, the cable bundler is a stuffing box.

[0014] Furthermore, it also includes a protective sleeve, the inner wall of which is provided with an annular stop surface, and the first positioning frame is pressed against the annular stop surface.

[0015] The liquid level monitoring device provided in this application has a positioning structure configured on the liquid level sensor. The positioning structure includes a first positioning frame and a second positioning frame detachably fixed to one side of the first positioning frame. The first positioning frame is fixedly connected to the cable by a cable tie in the middle. The positioning tube of the second positioning frame is sleeved on the outer periphery of the probe and cooperates with the positioning of the probe. This not only realizes the limiting installation of the liquid level sensor in the protective sleeve and restricts the shaking amplitude of the liquid level sensor along the radial direction of the protective sleeve, but also requires the opening of a threaded connection hole on the probe of the liquid level sensor, which reduces the difficulty of operation and avoids damage to the probe when opening the hole.

[0016] Other features, objects, and advantages of this application will become more apparent from the following detailed description of non-limiting embodiments with reference to the accompanying drawings:

[0017] Figure 1 This is a schematic diagram of the liquid level monitoring device for the liquid tank provided in the embodiments of this application. Detailed Implementation

[0018] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0019] This application provides a liquid tank level monitoring device for use in a ship's liquid tank to monitor the liquid level data within the tank.

[0020] Please refer to the attached document. Figure 1The liquid level monitoring device for a liquid tank provided in this application includes a liquid level sensor, a positioning structure, and a protective sleeve 300. The liquid level sensor is an immersion-type pressure liquid level sensor, which includes a connected probe 110 and a cable 120. Both the liquid level sensor and the positioning structure are installed inside the protective sleeve 300. The protective sleeve 300 is fixedly connected to the top plate of the liquid tank and extends through the top plate. The protruding end of the protective sleeve 300 is connected to the head portion of the liquid level sensor via a flange. The positioning structure includes a first positioning frame 210 and a second positioning frame 220, with the second positioning frame 220 disposed on one side of the first positioning frame 210. A cable tie 213 is provided in the middle of the first positioning frame 210, through which the cable 120 passes to achieve a fixed connection between the cable 120 and the cable tie 213. The second positioning frame 220 is provided with a positioning tube 221, which is sleeved on the outer periphery of the probe 110, and the positioning tube 221 and the probe 110 are positioned and fitted radially. The second positioning frame 220 and the first positioning frame 210 are detachably fixedly connected to facilitate the assembly between the positioning structure and the liquid level sensor. The assembly process between the positioning structure and the liquid level sensor is as follows: the first positioning frame 210 and the second positioning frame 220 are separated, then the cable 120 is threaded through the cable bundle 213 to fix the cable 120 to the cable bundle 213 and the probe 110 is threaded through the positioning tube 221. Then the first positioning frame 210 and the second positioning frame 220 are fixedly connected. Finally, the liquid level sensor with the positioning structure installed is inserted from the top opening of the protective sleeve 300 to the bottom of the protective sleeve 300.

[0021] In this embodiment, the first positioning frame 210 is fixedly connected to the cable 120 via the cable tie 213 in the middle. The positioning tube 221 of the second positioning frame 220 is sleeved on the outer periphery of the probe 110 and is positioned and cooperates with the probe 110. This not only realizes the limited installation of the liquid level sensor in the protective sleeve and restrains the shaking of the liquid level sensor in the radial direction along the protective sleeve 300, but also requires the opening of a threaded connection hole on the probe 110 of the liquid level sensor, which reduces the difficulty of operation and avoids damage to the probe 110 when opening the hole.

[0022] It should be understood that the portion of cable 120 that mates with cable bundler 213 is positioned close to probe 110 to reduce the volume of the positioning structure.

[0023] Optionally, the cable clamp 213 can be a stuffing box, which is not only easy to select materials for, but also provides a good fixing effect on the cable 120.

[0024] In some embodiments of this application, the first positioning frame 210 includes a positioning ring 211 and a plurality of first connecting rods 212. A cable tie 213 is located in the middle of the positioning ring 211. The plurality of first connecting rods 212 are located between the cable tie 213 and the positioning ring 211 and are spaced apart circumferentially around the cable tie 213. The two ends of the first connecting rods 212 are respectively connected to the cable tie 213 and the positioning ring 211. A first flow channel is formed between any adjacent first connecting rods 212, cable tie 213, and positioning ring 211 to facilitate the flow of liquid in the liquid tank to the bottom of the protective sleeve 300. The first positioning frame 210 described above has a simple structure and is easy to manufacture, which helps to reduce costs.

[0025] Optionally, the first positioning frame 210 includes four first connecting rods 212, which are evenly distributed around the circumference of the cable bundler 213. The first connecting rods 212 are welded to the positioning ring 211, and to the cable bundler 213. The cable bundler 213 and the positioning tube 221 are coaxially arranged.

[0026] The positioning ring 211 and the protective sleeve 300 have an assembly gap, which can be, but is not limited to, 2-4 mm.

[0027] In some embodiments of this application, the second positioning frame 220 includes a plurality of second connecting rods 222, which are spaced apart circumferentially around the positioning tube 221, wherein the two ends of the second connecting rods 222 are respectively connected to the positioning tube 221 and the positioning ring 211. The above-described second positioning frame 220 has a simple structure and is easy to manufacture, which helps to reduce costs.

[0028] Optionally, the second connecting rod 222 is inclined, which helps to reduce the volume of the positioning structure. The number of second connecting rods 222 and first connecting rods 212 are the same and they are arranged in a one-to-one correspondence. The second connecting rods 222 are welded to the positioning tube 221, and the corresponding second connecting rods 222 and first connecting rods 212 are screwed together.

[0029] In some embodiments of this application, the liquid level monitoring device further includes a protective sleeve 300. The inner wall of the protective sleeve 300 is provided with an annular stop protrusion 310. The side of the stop protrusion 310 away from the bottom wall of the protective sleeve is provided with an annular stop surface. The first positioning frame 210 is pressed against the annular stop surface to axially position the liquid level sensor located in the protective sleeve 300.
