Description

Technical Field

[0001] This application relates to the technical field of liquid leakage sensors, specifically an intelligent optical fiber principle liquid leakage sensor. Background Art

[0002] A liquid leakage sensor, also known as an optoelectronic leakage sensor, is an efficient sensor specifically used to monitor liquid leakage in liquid pipelines or containers. It mainly adopts the optoelectronic detection principle and realizes the timely detection and alarm of liquid leakage through precise optoelectronic induction technology. Generally, the liquid leakage sensor is installed at the pipeline connection to ensure that any leakage event can be quickly detected. When the leaked liquid contacts the optoelectronic induction probe on the sensor, the sensor will transmit the signal to the alarm device to trigger an alarm signal, reminding the operator to take necessary emergency measures, such as Figure 1 As shown, a liquid leakage sensor usually consists of the following components: a housing, an optoelectronic induction probe, a mounting base, and an optical fiber. The housing is the external protection structure of the sensor, which can effectively protect the internal components from the external environment. The optoelectronic induction probe is the core component of the sensor, which realizes the detection of the liquid state by emitting and receiving optical signals. The function of the mounting base is to fix the sensor at the pipeline connection to ensure that the sensor is always in the correct position. The optical fiber is used to transmit signals, transmitting the signals from the probe to the monitoring system for processing and alarm;

[0003] When installing the current liquid leakage sensor, first, it is necessary to drill holes at the pipeline connection so that the mounting base can be accurately placed in the appropriate position. Subsequently, bolts are passed through the mounting holes on the mounting base and tightened to the pipeline connection. This step takes a relatively long time and requires the cooperation of tools, and the overall installation process is relatively cumbersome, resulting in relatively low work efficiency.

[0004] Therefore, it is necessary to provide an intelligent optical fiber principle liquid leakage sensor to solve the above problems.

[0005] It should be noted that the above information disclosed in this background art section is only used to understand the background art of the concept of this application, and therefore, it may include information that does not constitute the prior art. Summary of the Invention

[0006] Based on the above problems existing in the prior art, the problem to be solved by this application is: to provide an intelligent optical fiber principle liquid leakage sensor to achieve the effect of convenient installation of the liquid leakage sensor.

[0007] The technical solution adopted by this application to solve its technical problems is: an intelligent optical fiber principle liquid leakage sensor, including a housing, a mounting base connected to the housing, an optoelectronic induction probe, and an optical fiber. The mounting base is provided with a connection component for connecting the pipeline;

[0008] The connecting component includes a first arc-shaped block and a second arc-shaped block rotatably connected to the mounting base. Clamping blocks for clamping the pipeline are symmetrically arranged on the inner sides of the first arc-shaped block and the second arc-shaped block;

[0009] A driving component for adjusting the distance between the two groups of clamping blocks is arranged on the first arc-shaped block and the second arc-shaped block, and a clamping component for fixing the first arc-shaped block and the second arc-shaped block is arranged at the ends of the first arc-shaped block and the second arc-shaped block.

[0010] Furthermore, the driving component includes a lead screw rotatably connected to the outer sides of the two groups of clamping blocks. The two lead screws are respectively threadedly connected to the first arc-shaped block and the second arc-shaped block. Guide rods are fixedly arranged on the outer sides of the two groups of clamping blocks, and the guide rods located on the outer sides of the two groups of clamping blocks respectively slide through the first arc-shaped block and the second arc-shaped block.

[0011] Furthermore, a connecting groove for connecting the clamping component is opened at one end of the second arc-shaped block, and a clamping groove communicating with the connecting groove is opened inside one end of the second arc-shaped block.

[0012] Furthermore, the clamping component includes a connecting block arranged at one end of the first arc-shaped block. The connecting block is adapted to the connecting groove. An inner cavity is opened inside the connecting block. A wedge-shaped block is slidably connected inside the inner cavity, and the wedge-shaped surface of the wedge-shaped block extends to the outside of the connecting block. The wedge-shaped block is adapted to the clamping groove. An elastic member is arranged inside the inner cavity.

[0013] Furthermore, an extruding component for extruding the wedge-shaped block in the clamping component is arranged at one end of the second arc-shaped block.

[0014] Furthermore, a through groove for the extruding component to move is opened inside the second arc-shaped block, and the through groove communicates with the clamping groove.

[0015] Furthermore, the extruding component includes a ejector rod slidably connected inside the through groove. One end of the ejector rod extends to the outside of the second arc-shaped block and is provided with a pressing plate.

[0016] Furthermore, the clamping block is arc-shaped and made of an elastic material. A guide groove is opened on the inner side of the clamping block.

[0017] Furthermore, grooves are symmetrically opened at the upper end of the mounting base. Connecting shafts are arranged at the connecting ends of the first arc-shaped block and the second arc-shaped block and the mounting base. The first arc-shaped block and the second arc-shaped block are rotatably connected inside the grooves through the connecting shafts.

[0018] Furthermore, a rotating handle is arranged at one end of the lead screw.

[0019] The beneficial effects of the present application are as follows: The intelligent optical fiber principle liquid leakage sensor provided by the present application rotates the first arc-shaped block and the second arc-shaped block, and connects the first arc-shaped block and the second arc-shaped block under the fit of the wedge-shaped block and the card slot in the clamping member, so that the two clamping blocks can be clamped on the pipeline, thereby completing the installation of the sensor. And through the driving component, the distance between the two clamping blocks can be adjusted to adapt to the use of more pipelines with different sizes, which is more convenient than using bolts for installation. And through the guiding groove inside the clamping block, when the pipeline leaks liquid, the liquid can flow to the photoelectric sensor, enabling the photoelectric sensor to detect liquid leakage more quickly, and transmitting the signal to the alarm device through the optical fiber, so that the staff can discover and handle it in time.

[0031] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0032] As Figure 1 shown, in order to solve the problem that currently when installing a leakage sensor, it is necessary to use tools to pass bolts through the mounting holes 21 on the mounting base 2 and fasten them to the pipeline connection, and the overall installation steps are relatively cumbersome, resulting in relatively low work efficiency, the specific solution of this scheme is as follows:

[0033] As Figures 2 to 4 shown, the present application provides an intelligent optical fiber principle liquid leakage sensor, including a housing 1, a mounting base 2 provided on the housing 1, a photoelectric induction probe 11 and an optical fiber 12. The optical fiber 12 is connected to the photoelectric induction probe 11 and is used to transmit signals, and transmit the signals generated by the photoelectric induction probe 11 to an alarm device or a monitoring device. A connecting component 3 for connecting a pipeline is provided on the mounting base 2;

[0034] The connecting component 3 includes a first arc-shaped block 31 and a second arc-shaped block 32 rotatably connected to the mounting base 2, and two groups of clamping blocks 33 symmetrically arranged inside the first arc-shaped block 31 and the second arc-shaped block 32. The two groups of clamping blocks 33 are arc-shaped and have a certain elasticity. The mounting base 2 is symmetrically provided with grooves 22. Connecting shafts 37 are provided at the ends of the first arc-shaped block 31 and the second arc-shaped block 32. The first arc-shaped block 31 and the second arc-shaped block 32 are rotatably connected to the inside of the grooves 22 through the connecting shafts 37. The grooves 22 are used to provide a rotating space for the first arc-shaped block 31 and the second arc-shaped block 32. Driving components 34 for adjusting the distance between the two groups of clamping blocks 33 are provided on both the first arc-shaped block 31 and the second arc-shaped block 32. A clamping member 35 for connecting the ends of the first arc-shaped block 31 and the second arc-shaped block 32 is provided at the ends of the first arc-shaped block 31 and the second arc-shaped block 32;

[0035] The driving component 34 includes a lead screw 341 rotatably connected to the outside of the clamping block 33. A rotating handle 3411 is provided at one end of the lead screw 341. The two lead screws 341 located outside the two groups of clamping blocks 33 are respectively threadedly connected to the first arc-shaped block 31 and the second arc-shaped block 32. Guide rods 342 are fixedly connected to the outside of the two groups of clamping blocks 33. The guide rods 342 outside the two groups of clamping blocks 33 respectively slide through the first arc-shaped block 31 and the second arc-shaped block 32. Guide grooves 331 are provided inside the two groups of clamping blocks 33. The guide grooves 331 are used to enable the leaked liquid to flow better to the photoelectric induction probe 11.

[0036] In this embodiment, as Figure 2 shown, in the initial state, the ends of the first arc-shaped block 31 and the second arc-shaped block 32 are in a separated state. At this time, place them at the pipe connection, and then rotate the first arc-shaped block 31 and the second arc-shaped block 32, as Figure 3As shown in the figure, the clamping part 35 can connect the ends of the first arc-shaped block 31 and the second arc-shaped block 32, so that the first arc-shaped block 31 and the second arc-shaped block 32 can be sleeved outside the pipeline. At this time, the clamping block 33 located between the first arc-shaped block 31 and the second arc-shaped block 32 can be clamped on the outside of the pipeline, so as to install the whole sensor on the outside of the pipeline, and make the photoelectric induction probe 11 at the lower end of the pipeline, which is more convenient than installing it with bolts. When the diameters of the pipelines are different, by rotating the two rotating handles 3411, the lead screw 341 rotates. Since the guide rods 342 located outside the two clamping blocks 33 respectively slide through the first arc-shaped block 31 and the second arc-shaped block 32, and the lead screw 341 is respectively threadedly connected with the first arc-shaped block 31 and the second arc-shaped block 32, when the two lead screws 341 rotate, the distance between the two clamping blocks 33 can be reduced or increased, so as to adapt to clamping pipelines with different diameters. At the same time, the clamping block 33 is arc-shaped and has a certain elasticity, so that the clamping block 33 can better fit the outside of the pipeline. When there is liquid leakage at the pipeline connection, the liquid can flow to the position of the photoelectric induction probe 11 along the guide groove 331 inside the clamping block 33. After the photoelectric induction probe 11 detects the liquid, it transmits the signal to the alarm device or the monitoring device through the optical fiber 12, so that the staff can timely discover the liquid leakage area of the pipeline and make timely treatment.

[0037] As Figures 5 to 6 shown in the figure, a connection groove 321 for connecting the clamping part 35 is opened at the end of the second arc-shaped block 32, and a clamping groove 322 communicated with the connection groove 321 is opened inside one end of the second arc-shaped block 32. The clamping part 35 includes a connection block 351 arranged at one end of the first arc-shaped block 31. The connection block 351 is adapted to the connection groove 321. An inner cavity 352 is opened inside the connection block 351. A wedge-shaped block 353 is slidably connected inside the inner cavity 352. One side of the wedge-shaped block 353 extends outside the inner cavity 352 and is adapted to the clamping groove 322. An elastic member 354 is arranged inside the inner cavity 352. The elastic member 354 is preferably a spring.

[0038] In this embodiment, when the first arc-shaped block 31 and the second arc-shaped block 32 are rotated and their ends are in contact, the connection block 351 at the end of the first arc-shaped block 31 is inserted into the connection groove 321 at the end of the second arc-shaped block 32. Under the extrusion of the inner wall of the connection groove 321, the wedge-shaped block 353 located outside the connection block 351 moves towards the inside of the inner cavity 352 and compresses the spring. When the connection block 351 is completely placed inside the connection groove 321, at this time, the wedge-shaped block 353 is located at the position of the clamping groove 322, and it is inserted into the clamping groove 322 under the elastic force of the spring, so that the connection block 351 can be fixed in the connection groove 321, thereby completing the connection of the ends of the first arc-shaped block 31 and the second arc-shaped block 32.

[0039] As Figure 6As shown in the figure, one end of the second arc-shaped block 32 is provided with a through groove 323 communicating with the card slot 322. An extrusion member 36 is arranged inside the through groove 323. The extrusion member 36 is used to extrude the wedge-shaped block 353 inside the connecting block 351. The extrusion member 36 includes a ejector rod 361 slidably connected inside the through groove 323. One end of the ejector rod 361 extends to the outside of the second arc-shaped block 32 and is provided with a pressing plate 362.

[0040] In this embodiment, when it is necessary to disassemble the whole sensor, by pressing the pressing plate 362, the pressing plate 362 drives the ejector rod 361 to move into the card slot 322, so that one end of the ejector rod 361 extrudes the wedge-shaped block 353 located inside the card slot 322, causing the wedge-shaped block 353 to move into the inner cavity 352 and compress the spring. Thus, the wedge-shaped block 353 is separated from the card slot 322. At this time, rotate the first arc-shaped block 31 and the second arc-shaped block 32 to separate the connecting block 351 from the connecting slot 321. At this time, the two clamping blocks 33 located outside the pipeline are separated from the pipeline, and the whole sensor can be removed from below the pipeline, which is convenient for repairing the pipeline when there is liquid leakage at the pipeline connection.

[0041] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
