Description

Technical Field

[0001] The invention belongs to the technical field of ship design, and in particular relates to a ship-used magnetic fastening type metal surface temperature measuring device and a ship. Background Art

[0002] There are a large number of metal pipes and equipment in ships, which are used for the transportation and storage of media such as steam, water, and lubricating oil. Temperature measurement sensors are widely used in ships to measure the temperature parameters of media or equipment in metal pipes. At present, the most commonly used temperature sensor on ships is the insertion type, which punches a hole in the metal pipe and inserts the temperature sensor into the pipe. The temperature of the medium in the pipe is directly measured by the sensor contacting the medium.

[0003] However, in some cases where the diameter of the pipeline is relatively small, inserting the temperature sensor will cause the pipeline to be blocked; or in cases where the pipeline safety level is high and drilling is not recommended, the surface temperature measurement method is usually used. The most commonly used sensor on ships is the ferrule-type surface temperature measurement sensor. The metal ferrule is customized according to the diameter of the pipeline, and the sensor is fixed on the surface of the pipeline using the metal ferrule.

[0004] In actual use, the following problems exist: 1) The metal ferrule needs to be customized to match the diameter of the pipe. Once the metal ferrule is damaged, it needs to be replaced or remade, and its versatility is poor; 2) Once the metal ferrule is fixed and installed, it cannot be adjusted. After a period of thermal expansion and contraction on the pipeline, the metal ferrule may break or loosen, resulting in insufficient contact between the temperature measurement probe and the pipe surface; 3) Ships are subject to impact and vibration environments, and the contact between the temperature measurement probe and the pipe surface often becomes loose, resulting in delayed, inaccurate temperature measurement or the inability to obtain measurement parameters.

[0005] Therefore, how to provide a marine magnetically fastened metal surface temperature measuring device and a ship, which can ensure that the temperature measuring device is firmly installed, has good installation adjustability, the temperature measuring probe is in full and stable contact with the metal pipe surface, and integrates measurement signal processing, parameter display and signal output functions, has become a technical problem that needs to be solved urgently.

[0030] In order to solve the problem that metal pipes with smaller diameters cannot be punched to insert temperature sensors, and that pipes with high safety requirements cannot be punched to insert temperature measuring probes, based on the good thermal conductivity of metal pipes, the temperature of the medium such as steam, water, and lubricating oil in the pipe can be indirectly obtained by measuring the temperature of the metal pipe surface; the metal ferrule of the commonly used card sleeve surface temperature measurement sensor needs to be customized to match the pipe diameter size, and once the metal ferrule is damaged, it needs to be replaced or remade, which has poor versatility; the metal ferrule of the commonly used card sleeve surface temperature measurement sensor is prone to breakage and loosening after thermal expansion and contraction.

[0049] like Figure 1 and Figure 2 As shown, Figure 1 A schematic diagram showing the structure of a ship-based magnetically fastened metal surface temperature measuring device according to an embodiment of the present invention; Figure 2 A schematic diagram showing the installation of a ship-based magnetically fastened metal surface temperature measuring device according to an embodiment of the present invention.

[0050] Figure 1 A marine magnetic fastening metal surface temperature measuring device is disclosed, comprising: a signal processing transmitter 1, a signal interface 2, a signal line 3, a parameter display screen 4, an insulation layer extension tube 5, a multi-layer adjustable magnetic suction piece 6, a magnetic suction piece position adjustment hole 7, a connecting stud 8, a magnetic suction piece fastening nut 9, a temperature measuring probe spring 10, a temperature measuring probe 11, a lifting ear 12, a metal auxiliary fixing rope 13, and an adjustable fastening buckle 14.

[0053] The technical solution of the present invention is based on the good thermal conductivity of metal pipes. The temperature of the pipe surface is measured by contacting the temperature measuring probe with the surface of the metal pipe, and the temperature of the medium such as steam, water, and lubricating oil in the pipe is indirectly obtained. This solves the problem that metal pipes with smaller diameters cannot be punched to insert temperature measuring probes, and pipes with high safety requirements cannot be punched to insert temperature measuring probes.

[0054] The sensor is installed firmly by adsorbing the multi-layer adjustable magnetic suction piece to the metal pipe surface. The adsorption contact surface between the multi-layer adjustable magnetic suction piece and the pipe surface can be adjusted up and down through the magnetic suction piece position adjustment hole to improve the fit to the surface, increase the contact surface with the pipe surface, and ensure sufficient magnetic adsorption and tightening; and the multi-layer magnetic suction piece position is tightened by tightening the studs and magnetic suction piece fastening nuts. A temperature measurement probe telescopic spring is designed at the front end of the temperature measurement probe, which has telescopic elasticity. When the temperature measurement probe is squeezed and contacted with the metal pipe surface, the rebound force of the temperature measurement probe telescopic spring can ensure sufficient and firm contact between the probe and the metal pipe surface; solve the problem of looseness and poor contact between the temperature measurement probe and the metal pipe surface.

[0055] In the embodiment of the present invention, the temperature measuring device is auxiliary fastened by a metal auxiliary fixing rope to ensure that the sensor will not fall off when impacted; the tightness of the metal auxiliary fixing rope is adjusted by an adjustable fastening buckle to adapt to pipes of different diameters.

[0056] In an embodiment of the present invention, a marine magnetic fastening type metal surface temperature measuring device adopts a magnetic fastening installation method, which is easy to install and enhances the fastening force between the sensor and the metal pipe; the installation of the sensor is not limited by the pipe diameter and the thickness of the pipe surface insulation layer; the multi-layer adjustable magnetic suction piece adjusts the fit between the sensor magnetic suction piece and the metal pipe surface through up and down displacement and the magnetic suction piece fastening nut, increases the contact surface, and ensures that the magnetic suction force is firm; during the extrusion process between the temperature measuring probe and the pipe surface, the rebound force of the temperature measuring probe spring can ensure that the probe is in full and firm contact with the pipe surface; the temperature measuring device is auxiliary fastened by a metal auxiliary fixing rope to ensure that the sensor will not fall off when impacted; the tightness of the metal auxiliary fixing rope can be adjusted by an adjustable fastening buckle to adapt to pipes of different diameters.

[0057] The embodiment of the present invention has the functions of signal processing, output and display. It is easy to disassemble by untying the metal auxiliary fixing rope, pulling out the multi-layer adjustable magnetic suction sheet of the sensor with external force or prying it with a tool, so that the multi-layer adjustable magnetic suction sheet is separated from the metal pipe. It does not damage the pipe or sensor and can be reused.

[0058] In one embodiment of the present invention, a temperature measurement position is selected on a metal pipe, and the pipe surface is cleaned by rust removal, oil removal, etc. The sensor is adsorbed and fixed at the measurement position by unfastening the adjustable fastening buckle of the sensor and utilizing the adsorption force of the multi-layer adjustable magnetic suction sheet.

[0059] By loosening the magnetic suction piece fastening nut, use external force to press the multi-layer adjustable magnetic suction piece downward from the inside to the outside to ensure that each layer of the magnetic suction piece contacts the surface of the metal pipe to form an arc-shaped contact and fitting surface. Tighten the magnetic suction piece fastening nut to fix the position of the multi-layer adjustable magnetic suction piece; wrap the metal auxiliary fixing rope around the metal pipe from both sides, connect it with the adjustable fastening buckle, adjust the tightness, and then tighten the metal auxiliary fixing rope.

[0060] If the pipeline surface needs to be covered with a retaining layer, ensure that the sensor transmitter and display are outside the insulation layer; connect the sensor to the signal line of the external display or control device to output the measurement signal. When the sensor needs to be moved or disassembled, untie the metal auxiliary fixing rope, pull out the sensor with external force or pry the sensor with tools to separate the multi-layer adjustable magnetic suction sheet from the metal pipeline.

[0061] In yet another embodiment of the present invention, a ship is provided, the ship comprising any one of the above-mentioned ship-used magnetically fastened metal surface temperature measuring devices.

[0062] The embodiment of the present invention provides a ship-use magnetic fastening type metal surface temperature measuring device and ship, including: a signal processing transmitter, a signal interface, a multi-layer adjustable magnetic suction piece, a temperature measuring probe spring, a temperature measuring probe, a fastening connection device and an adjustable fastening buckle.
