Description

Technical Field

[0001] This utility model relates to the technical field of passive wireless temperature measurement, specifically to a passive wireless temperature measurement system for power equipment. Background Technology

[0002] A passive wireless thermometer is a sensor device that transmits temperature data wirelessly without requiring batteries or an external power source. It has a wide range of applications due to its maintenance-free operation, long lifespan, high reliability, and suitability for special environments.

[0003] The passive wireless temperature sensor mainly consists of three modules: a passive wireless temperature sensor probe, a data reader, and a back-end monitoring system. The passive wireless temperature sensor probe includes a temperature-sensitive element, an energy harvesting module, a signal processing circuit, an antenna, and a housing. The energy harvesting module typically involves wrapping a permalloy strip around the outside of the current-carrying area to extract power through electromagnetic induction. The permalloy also serves as a strap to secure the temperature sensor. In actual installation, while the permalloy strip is convenient for installation, it also limits the installation location of the temperature sensor, requiring it to be installed in a location where current can pass through to extract power. Therefore, a passive wireless temperature measurement system for power equipment needs to be designed. Utility Model Content

[0004] To address the aforementioned technical problems, the purpose of this utility model is to overcome the limitation on the installation position when using permalloy strips to install temperature sensors in the prior art.

[0005] To achieve the above objectives, this utility model provides a passive wireless temperature measurement system for power equipment, comprising: a thermometer, a permalloy strip that slides through the thermometer, a connecting mechanism for connecting the two ends of the permalloy strip, and a pair of symmetrical magnetic mounting mechanisms that are detachably assembled on the thermometer.

[0006] The magnetic mounting mechanism includes a magnet and an elastic element whose end can be pressed against the side of the thermometer away from the temperature measurement contact point.

[0007] Preferably, the thermometer includes a housing, and two opposite outer walls of the housing are provided with mounting portions that match the corresponding magnetic mounting mechanisms. The mounting portions are located away from the temperature measuring contact point of the thermometer.

[0008] The magnetic mounting mechanism also includes a mounting plate fixedly connected to the magnet and several first mounting bolts that are threadedly connected to the mounting plate and slide through the mounting part.

[0009] Preferably, the elastic element includes a plurality of springs that are fitted one-to-one on the corresponding first mounting bolts, and the two ends of the springs abut against the head and mounting part of the first mounting bolt, respectively.

[0010] Preferably, a threaded tube matching the first mounting bolt is fixedly connected to the mounting plate, and the first mounting bolt is threadedly assembled onto the threaded tube.

[0011] Preferably, the magnet is provided with a plurality of countersunk holes, and each countersunk hole is provided with a second mounting bolt that is mounted on the mounting plate.

[0012] Preferably, the permalloy strip is detachably fitted with several rubber support members.

[0013] Preferably, the connecting mechanism includes a connecting sleeve and a locking bolt threaded onto the connecting sleeve.

[0014] According to the above technical solution, the passive wireless temperature measurement system for power equipment provided by this utility model has the following beneficial effects in use:

[0015] Firstly, the permalloy strip can be used as a strap, eliminating the need for a magnetic mounting mechanism. Alternatively, a pair of magnetic mounting mechanisms can be mounted on the thermometer, and the permalloy strip can be wrapped around other objects through which current flows before passing through the thermometer, thus expanding the range of applications for the thermometer. The two selectable mounting methods enhance the flexibility of installation.

[0016] Secondly, the elastic element ensures that the temperature measuring contact point of the thermometer is always in contact with the metal part. Even when there is a height difference between the temperature measuring contact point on the magnet and the surface of the metal part, the elastic element can still ensure that the temperature measuring contact point of the thermometer is in contact with the surface of the metal part, thus improving practicality.

[0017] Other features and advantages of this utility model will be described in detail in the following detailed description section; and all parts not covered in this utility model are the same as or can be implemented using existing technology. Attached Figure Description

[0025] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0026] In this utility model, unless otherwise stated, directional words such as "upper," "lower," "inner," and "outer" included in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.

[0027] like Figure 1-4 As shown, a passive wireless temperature measurement system for power equipment includes: a thermometer 1, a permalloy strip 2 that slides through the thermometer 1, a connecting mechanism for connecting the two ends of the permalloy strip 2, and a pair of symmetrical magnetic mounting mechanisms that are detachably assembled on the thermometer 1.

[0028] The magnetic mounting mechanism includes a magnet 3 and an elastic element 4 whose end can be pressed against the side of the thermometer 1 away from the temperature measuring contact point.

[0029] In the above technical solution, when in use, the permalloy strip 2 can be passed through the thermometer 1. The permalloy strip 2 also functions as a strap to tie the thermometer 1 to the corresponding object. The permalloy strip 2 draws power through the principle of electromagnetic induction, so there is no need to assemble a magnetic installation mechanism.

[0030] Alternatively, a pair of magnetic mounting mechanisms can be mounted on the thermometer 1. The thermometer 1 can be mounted on a metal part through the magnetic mounting mechanism. Then, the permalloy strip 2 can be wrapped around other objects through which current flows and then passed through the thermometer 1. At this time, the permalloy strip 2 draws power through adjacent objects through which current flows, thus expanding the application range of the thermometer 1.

[0031] The appropriate assembly method can be selected according to the specific environment. The permalloy strap 2 can be used for binding or the magnet 3 can be used for magnetic installation. The two selectable installation methods improve the flexibility of installation.

[0032] The elastic element 4 ensures that the temperature measuring contact point of the thermometer 1 is always in contact with the metal part. Even when there is a height difference between the temperature measuring contact point on the magnet 3 and the surface of the metal part, the elastic element 4 can still ensure that the temperature measuring contact point of the thermometer 1 is in contact with the surface of the metal part, thus improving practicality.

[0033] In a preferred embodiment of the present invention, the thermometer 1 includes a housing, and mounting portions 5 that match the corresponding magnetic mounting mechanisms are protruding from the two opposite outer walls of the housing. The mounting portions 5 are located away from the temperature measuring contact point of the thermometer 1.

[0034] The magnetic mounting mechanism also includes a mounting plate 6 fixedly connected to the magnet 3 and several first mounting bolts 7 threadedly connected to the mounting plate 6 and sliding through the mounting part 5.

[0035] In the above technical solution, when magnetic installation is selected, the first mounting bolt 7 is removed from the mounting plate 6, then passed through the mounting part 5 and assembled on the mounting plate 6. At this time, the mounting part 5 can slide on the first mounting bolt 7. Under the action of the elastic element 4, the temperature measuring contact point of the thermometer 1 can contact the surface of the metal part at different heights, making the operation simple and convenient.

[0036] In a preferred embodiment of the present invention, the elastic element 4 includes a plurality of springs that are fitted one-to-one on the corresponding first mounting bolts 7, and the two ends of the springs respectively abut against the head and the mounting part 5 of the first mounting bolts 7.

[0037] In a preferred embodiment of the present invention, a threaded tube 8 that matches the first mounting bolt 7 is fixedly connected to the mounting plate 6, and the first mounting bolt 7 is threadedly assembled on the threaded tube 8.

[0038] In the above technical solution, rotating the first mounting bolt 7 can adjust the distance between the head of the first mounting bolt 7 and the end of the threaded tube 8, that is, adjust the distance between the head of the first mounting bolt 7 and the mounting part 5, adjust the degree of spring compression, and thus adjust the force applied by the spring to the mounting part 5.

[0039] In a preferred embodiment of this utility model, the magnet 3 is provided with a plurality of countersunk holes, and each countersunk hole is provided with a second mounting bolt 9 mounted on the mounting plate 6.

[0040] In the above technical solution, the magnet 3 can be replaced by removing the second mounting bolt 9. Depending on the metal parts and the usage environment, magnets 3 with different magnetic strengths can be replaced.

[0041] In a preferred embodiment of this utility model, a plurality of rubber support members 10 are detachably sleeved on the permalloy strip 2.

[0042] In a preferred embodiment of the present invention, the connecting mechanism includes a connecting sleeve 12 and a locking bolt 11 threadedly mounted on the connecting sleeve 12.

[0043] In the above technical solution, the ends of the permalloy strip 2 pass through the connecting sleeve 12, and the ends of the locking bolts 11 can cooperate with the inner wall of the connecting sleeve 12 to tightly clamp the permalloy strip 2.

[0044] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0045] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0046] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
