Description

Technical Field

[0001] This utility model relates to the field of pipeline monitoring technology, and in particular to a device for monitoring the status of ship pipelines. Background Technology

[0002] Piping systems on ships are an important part of their infrastructure. These pipes are like blood vessels in the human body, ensuring the normal operation of the ship. Ship piping systems include fuel lines, cooling lines, lubricating oil lines, and fire-fighting lines, etc.

[0003] The internal temperature of pipelines is crucial. Temperature sensors are typically used to detect the temperature of flowing liquids. These sensors sense temperature and convert it into a usable output signal. Once connected to equipment, they monitor temperature conditions. However, in most common equipment, sensors are fixedly installed. When a sensor is damaged and needs replacement, disassembly and reassembly are inconvenient, requiring significant time and disrupting normal pipeline operation, causing inconvenience. Furthermore, the reinstalled device must be properly sealed to prevent leaks. Therefore, we designed a shipboard pipeline condition monitoring device. Utility Model Content

[0004] The purpose of this invention is to provide a shipboard pipeline status monitoring device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A shipboard pipeline status monitoring device includes a monitoring pipeline, a three-way valve body, and a sensor housing. A temperature probe is located at the bottom of the sensor housing. The monitoring pipeline includes an integrally formed left-hand bend and a right-hand bend. A handle is provided on the surface of the three-way valve body. The inlet end of the three-way valve body is connected to the left delivery pipeline, and the outlet end is connected to the left bend. A connecting pipe is connected to the other outlet end of the three-way valve body, and the other end of the connecting pipe is connected to the right delivery pipeline. The end of the right bend away from the left bend is connected to the surface of the connecting pipe. A protective outer shell is fixedly fitted around the monitoring pipeline. A mounting base is provided on the upper side of the pipeline surface. A fixing plate is fixed between the inner top wall of the protective shell and the surface of the monitoring pipeline. A sliding groove is opened on the left side surface of the fixing plate. A threaded rod is rotatably provided between the upper and lower inner walls of the sliding groove. A moving block is threaded on the outer side of the threaded rod. The moving block is slidably disposed in the sliding groove. A lifting block is fixedly connected to the left side surface of the moving block through a connecting block. The sensor housing is detachably installed on the lifting block. A mounting groove for embedding the sensor housing is opened on the top of the mounting base. A socket for inserting a temperature probe is opened on the inner bottom wall of the mounting groove. The socket communicates with the inside of the monitoring pipeline.

[0007] As a preferred embodiment of this utility model: the sensor housing is cylindrical and has an external thread on the upper part of its outer surface; the lifting block has a through-hole for mounting screws that mate with the external thread; a limiting ring is fixedly fitted on the outer side of the sensor housing, and the limiting ring is located at the top of the external thread.

[0008] As a further preferred embodiment of this utility model: the lower part of the outer surface of the sensor housing is provided with a plurality of tightly connected sealing rubber rings, the sealing rubber rings are located below the external thread, the bottom of the sensor housing is provided with a second sealing rubber gasket, the second sealing rubber gasket is sleeved on the outer periphery of the top of the temperature probe, and the bottom of the lifting block is provided with a first sealing rubber gasket.

[0009] As a further preferred embodiment of this utility model: the top of the sensor housing is provided with a monitoring panel, the front surface of the monitoring panel is provided with a temperature display screen and an alarm, the front side of the protective shell is provided with an observation window, and the surface of the observation window is provided with multiple small holes.

[0010] As a further preferred embodiment of this utility model: the top of the protective shell is provided with a drive motor, and the output shaft of the drive motor is connected to the top end of the threaded rod.

[0011] As a further preferred embodiment of this utility model: the connecting pipe is provided with a one-way valve inside, and the one-way valve is located on the left side of the connection between the right bend pipe and the connecting pipe.

[0012] As a further preferred embodiment of this utility model: a cover plate is movably provided on the top left side of the protective shell, and the mounting seat is located below the cover plate.

[0013] The beneficial effects of this utility model are:

[0014] 1. During the maintenance and disassembly / reassembly of the sensor housing, this device drives the output shaft of the drive motor to rotate the threaded rod, which in turn moves the moving block vertically. This, in turn, moves the lifting block up and down via the connecting block, thereby moving the sensor housing mounted on the lifting block up and down. This allows for the automatic disassembly and assembly of the sensor housing and the mounting base, improving the convenience of disassembly and assembly operations and increasing work efficiency. In particular, when the lifting block rises to its highest point, the cover can be opened, and the operator can easily disassemble and assemble the sensor housing and the lifting block by twisting the sensor housing. The operation is simple and convenient.

[0015] 2. This device can change the direction of liquid flow in the pipeline through the setting of the three-way valve body. When the temperature probe needs to be repaired or replaced, turn the handle to change the liquid flow direction to left delivery pipeline - connecting pipe - right delivery pipeline. Therefore, during the replacement operation, the liquid in the pipeline of the ship flows normally and the flow will not affect the replacement and maintenance operation. After the replacement and maintenance operation is completed, turn the handle again to change the liquid flow direction back to the initial state and continue to maintain the monitoring function of the pipeline.

[0016] 3. In this device, the sensor housing descends along with the lifting block until the temperature probe extends into the pipe. At this point, the lower part of the sensor housing is embedded in the mounting groove, and the lifting block abuts against the mounting base. The installation seal is improved by the compression deformation of the first sealing rubber gasket, further improved by the compression deformation of the sealing ring, and further improved by the compression deformation of the second sealing rubber gasket. Therefore, this device forms a triple sealing effect at three different positions in the vertical direction, fully ensuring the installation seal and preventing leakage that would affect the practicality of the device.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0024] Please see Figure 1-4 In this embodiment of the present invention, a shipboard pipeline status monitoring device includes a monitoring pipeline, a three-way valve body 2, and a sensor housing 18. A temperature probe 17 is provided at the bottom of the sensor housing 18. The monitoring pipeline includes an integrally formed left bend 10 and a right bend 6. A handle 3 is provided on the surface of the three-way valve body 2. The inlet end of the three-way valve body 2 is connected to the left delivery pipeline 1, and the outlet end of the three-way valve body 2 is connected to the left bend 10. A connecting pipe 4 is connected to the other outlet end of the three-way valve body 2, and the other end of the connecting pipe 4 is connected to the right delivery pipeline 5. The end of the right bend 6 away from the left bend 10 is connected to the surface of the connecting pipe 4. A protective shell 7 is fixedly fitted over the monitoring pipeline, and a cover plate 8 is movably provided on the top left side of the protective shell 7. A mounting base 21 is provided on the upper side of the surface of the monitoring pipeline. The mounting base 21 is located below the cover plate 8. A fixing plate 14 is fixed between the inner top wall of the protective shell 7 and the surface of the monitoring pipeline. A sliding groove is provided on the left side surface of the fixing plate 14. A threaded rod 16 is rotatably provided between the upper and lower inner walls of the sliding groove. A moving block 15 is fitted on the outer thread of the threaded rod 16. The moving block 15 is slidably disposed in the sliding groove. A lifting block 19 is fixedly connected to the left side surface of the moving block 15 through a connecting block 25. The sensor housing 18 is detachably installed on the lifting block 19. A mounting groove 22 is provided on the top of the mounting base 21 for the sensor housing 18 to be embedded. An insertion hole is provided on the inner bottom wall of the mounting groove 22 for the temperature probe 17 to be inserted. The insertion hole communicates with the inside of the monitoring pipeline.

[0025] The sensor housing 18 is cylindrical and has an external thread on the upper part of its outer surface. The lifting block 19 has a through-hole for mounting screws that mate with the external thread. A limiting ring 26 is fixedly fitted on the outer side of the sensor housing 18. The limiting ring 26 is located at the top of the external thread. The sensor housing 18 and the lifting block 19 are connected by threads. The limiting ring 26 serves to limit the installation.

[0026] The lower part of the outer surface of the sensor housing 18 is provided with multiple tightly connected sealing rings 24, which are located below the external thread. The bottom of the sensor housing 18 is provided with a second sealing rubber gasket 23, which is sleeved around the top periphery of the temperature probe 17. The bottom of the lifting block 19 is provided with a first sealing rubber gasket 20. When the sensor housing 18 is threaded onto the lifting block 19, the sensor housing 18 descends with the lifting block 19 until the temperature probe 17 extends into the pipe. At this time, the lower part of the sensor housing 18 is embedded in the mounting groove 22, and the lifting block 19 abuts against the mounting base 21. The installation sealing performance is improved by the compression deformation of the first sealing rubber gasket 20, further improved by the compression deformation of the sealing rings 24, and further improved by the compression deformation of the second sealing rubber gasket 23. Therefore, this device forms a triple sealing effect at three different positions in the vertical direction, which fully ensures the installation sealing performance and avoids leakage, thus affecting the practicality of the device.

[0027] The top of the sensor housing 18 is provided with a monitoring panel 27. The front surface of the monitoring panel 27 is provided with a temperature display screen and an alarm. The front of the protective housing 7 is provided with an observation window 9. The surface of the observation window 9 is provided with multiple small holes 12. The observation window 9 is designed to allow staff to view the monitoring panel 27 during inspection. When the temperature probe 17 detects a temperature greater than the preset value, the alarm will sound. The multiple small holes 12 ensure that the alarm sound can be effectively transmitted to remind staff.

[0028] The protective housing 7 has a drive motor 13 on its top. The output shaft of the drive motor 13 is connected to the top of the threaded rod 16 to drive the threaded rod 16 to rotate, thereby driving the moving block 15 to move vertically. This, in turn, drives the lifting block 19 to move up and down through the connecting block 25, which in turn drives the sensor housing 18 mounted on the lifting block 19 to move up and down. This allows for the automatic disassembly and assembly of the sensor housing 18 and the mounting base 21, improving the convenience of disassembly and assembly operations and increasing work efficiency. In addition, when the lifting block 19 rises to its highest position, the operator can disassemble and assemble the sensor housing 18 and the lifting block 19 by twisting the sensor housing 18. This is the only place where manual operation is required.

[0029] The connecting pipe 4 is equipped with a one-way valve 11, which is located on the left side of the connection between the right bend pipe 6 and the connecting pipe 4. The liquid flow direction of this device is left delivery pipe 1—left bend pipe 10—right bend pipe 6—right delivery pipe 5. The one-way valve 11 prevents the liquid from flowing back in the connecting pipe 4. When the temperature probe 17 needs to be repaired or replaced, the handle 3 is turned so that the liquid flow direction becomes left delivery pipe 1—connecting pipe 4—right delivery pipe 5. Therefore, during the replacement operation, the liquid in the ship's pipeline flows normally and the flow will not affect the replacement and maintenance operation. After the replacement and maintenance operation is completed, the handle 3 is turned again to change the liquid flow direction back to the initial state and continue to maintain the monitoring function of the pipeline.

[0030] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
