Technical Field

[0001] The present invention relates to the technical field of temperature measurement, and more particularly to a temperature measuring device. Background Art

[0002] In industry, there are various components (such as equipment, pipelines, etc.) whose surfaces need to measure temperature. The common practice is to install a thermometer on the surface of the component to be measured to achieve temperature measurement. However, in addition to the thermometer, other accessories are also installed on the surface of the component to be measured, such as a heater, an insulation layer, etc. Since the thermometer needs to be in contact with the surface of the component to be measured in order to accurately measure the temperature, the accessories are usually installed on the outside of the thermometer and cover the thermometer. This results in the need to remove the accessories on the surface of the component to be measured when replacing the thermometer, which makes the replacement time too long. For some special working environments, such as high temperature environments and high radioactivity environments, workers cannot work in these environments for too long, so it is required to be able to quickly replace the thermometer. Existing temperature measuring devices cannot meet the above requirements for rapid replacement of thermometers. Summary of the invention

[0003] The object of the present invention is to provide a temperature measuring device to achieve rapid replacement of a thermometer and meet the requirements in a special working environment.

[0004] Based on the above purpose, the present invention provides a temperature measuring device for measuring the temperature of a component to be measured, wherein the outer side of the component to be measured is covered with an appendage, and the temperature measuring device includes a sleeve and a thermometer, wherein the sleeve is arranged on the outer side of the component to be measured, and the appendage covers at least a portion of the sleeve, one end of the sleeve leads to the component to be measured, and the other end of the sleeve extends to the outside of the appendage; at least a portion of the thermometer is located in the sleeve, and one end of the thermometer extends from one end of the sleeve leading to the component to be measured and maintains contact with the component to be measured.

[0005] Furthermore, one end of the thermometer away from the temperature-measured component extends from one end of the sleeve away from the temperature-measured component to the outside of the sleeve.

[0006] Furthermore, the sleeve is fixed to the outer wall of the temperature-measured element by a first fastening element.

[0007] Furthermore, the first fastening element is sleeved on the outer side of the temperature-measured element, and an opening is provided on the first fastening element. One end of the sleeve passes through the opening and is fixedly connected to the first fastening element.

[0008] Furthermore, it also includes an elastic member, which is respectively connected to the sleeve and the thermometer, and is used to provide an elastic force to the thermometer so that the thermometer presses against the temperature-measured element.

[0009] Furthermore, the elastic member is fixed on the sleeve and is in a stretched state.

[0010] Furthermore, the elastic member is fixedly connected to the thermometer via a second fastening element.

[0011] Furthermore, the elastic member is a spring, one end of the spring is fixed to an end of the sleeve away from the temperature element to be measured, and one end of the thermometer sequentially passes through the spring and the sleeve and contacts the temperature element to be measured.

[0012] Furthermore, the spring is coaxially arranged with the sleeve.

[0013] Furthermore, a wire is provided on one end of the thermometer away from the temperature-measured element, so that temperature data measured by the thermometer can be obtained through the wire.

[0014] The temperature measuring device of the present invention has a sleeve arranged outside the temperature element to be measured, one end of the sleeve leads to the temperature element to be measured, and the other end extends out of the appendage, and the thermometer is located in the sleeve, so that the thermometer can be easily taken out of the sleeve or installed in the sleeve, thereby realizing rapid replacement of the thermometer and meeting the requirements in special working environments. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 Schematic diagram of the structure of a temperature measuring device according to an embodiment of the present invention. DETAILED DESCRIPTION

[0016] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings and described in detail.

[0017] like Figure 1As shown, an embodiment of the present invention provides a temperature measuring device for measuring the temperature of a component 100 to be measured. An appendage 110 (such as a heater, a heat preservation layer, etc.) is provided on the outer side of the component 100 to be measured. The appendage 110 covers the component 100 to be measured. The temperature measuring device includes a sleeve 200 and a thermometer 300. The sleeve 200 is arranged on the outer side of the component 100 to be measured. The appendage 110 covers at least a portion of the sleeve 200. One end of the sleeve 200 leads to the component 100 to be measured, and the other end extends to the outside of the appendage 110. The thermometer 300 is at least partially located in the sleeve 200. One end of the thermometer 300 extends from one end of the sleeve 200 leading to the component 100 to be measured and keeps contact with the component 100 to be measured, thereby measuring the temperature of the component 100 to be measured. Since the end of the sleeve 200 away from the temperature-measured element 100 is located outside the appendage 110, when replacing the thermometer 300, it is only necessary to remove the thermometer 300 from the sleeve 200 from this end, and then put the new thermometer 300 into the sleeve 200 without removing the appendage 110, thereby saving a lot of time and achieving rapid replacement of the thermometer 300 to meet the requirements under special working environments.

[0018] In some embodiments, one end of the thermometer 300 away from the temperature-measured component 100 may extend from one end of the sleeve 200 away from the temperature-measured component 100 , so that the thermometer 300 may be easily removed from the sleeve 200 .

[0019] In some embodiments, the sleeve 200 can be fixed to the outer wall of the temperature element 100 to be measured by the first fastening element 400. The first fastening element 400 can be a clamp, a cable tie or any other suitable fastener. The first fastening element 400 is sleeved on the outer side of the temperature element 100 to be measured, and an opening is opened on it. One end of the sleeve 200 passes through the opening and is fixedly connected to the first fastening element 400. In this way, the sleeve 200 can be fixed to the temperature element 100 to be measured by the first fastening element 400, and the end of the sleeve 200 can lead to the temperature element 100 to be measured without being blocked by the first fastening element 400. The sleeve 200 can be welded, clamped, bonded or fixed in any other way with the first fastening element 400.

[0020] Exemplarily, the first fastening element 400 is a clamp, which includes a band 410 and a screw 420. The band 410 is sleeved on the outside of the temperature element 100 to be measured, and the screw 420 is used to adjust the tightness of the band 410. The opening is set on the band 410 for the sleeve 200 to pass through. The sleeve 200 can be pre-welded on the band 410, and then during installation, the band 410 can be sleeved on the outside of the temperature element 100 to be measured, and then the band 410 is tightened to the temperature element 100 to be measured by rotating the screw 420, so that the two are fastened.

[0021] In some embodiments, the temperature measuring device may further include an elastic member 500, which is respectively connected to the sleeve 200 and the thermometer 300, and is used to provide an elastic force to the thermometer 300, which will make the thermometer 300 lean against the outer wall of the temperature-measured element 100 and maintain a good contact state. The elastic member 500 may be a spring, a spring sheet, or any other suitable elastic element.

[0022] The elastic member 500 can be welded to the sleeve 200. By applying a tensile force to the elastic member 500, it is put into a stretched state. In the stretched state, it is fixed to the thermometer 300 through the second fastening element 600, and then the tensile force applied to the elastic member 500 is cancelled. In this way, the elastic member 500 will have a tendency to return to its original state, so that the thermometer 300 is tightly pressed against the temperature-measured element 100.

[0023] The second fastening element 600 may be a clamp, a cable tie or any other suitable fastener.

[0024] Exemplarily, the elastic member 500 is a spring, which is coaxially arranged with the sleeve 200, and one end of the spring is welded to one end of the sleeve 200 extending out of the appendage 110, and one end of the thermometer 300 passes through the spring and the sleeve 200 in sequence and contacts the temperature element 100 to be measured, and then the spring is stretched, and after stretching, a clamp 600 is put on the outside of the spring, and the clamp 600 is tightened so that the spring is fixed together with the thermometer 300 in the stretched state, and then the external force is removed, and the spring will have a tendency to return to its original state, so that the thermometer 300 is tightly against the temperature element 100 to be measured.

[0025] In some embodiments, a wire 310 is provided on one end of the thermometer 300 away from the temperature-measured element 100 . The thermometer 300 can transmit electronic signals through the wire 310 , and the temperature data measured by the thermometer 300 can be obtained by converting the electronic signals.

[0026] In some embodiments, the thermometer 300 may be a thermal resistor, a thermocouple, or any other suitable sensor for measuring temperature.

[0027] In some embodiments, the temperature-measured element 100 may be various pipes, valves, containers, and other equipment that require temperature measurement.

[0028] In some embodiments, the first fastening element 400 may be made of metal, plastic, or any other suitable material as long as it can function normally at the operating temperature of the temperature-measured element 100 .

[0029] In some embodiments, the elastic member 500 may be made of metal, plastic, or any other suitable material as long as it can function normally at the operating temperature of the temperature-measured element 100 .
