The invention provides a temperature measuring device which is suitable for measuring the temperature of goods in a unfreezing warehouse during unfreezing. The temperature measuring device provided by the invention comprises a fixed support 5, wherein the fixed support 5 is provided with an installation structure for being installed in a temperature measuring environment; the fixed bracket 5 may be mounted in a suitable position in the thawing warehouse and may also be mounted in a suitable position in a railway wagon, and the specific embodiment of the fixed bracket 5 mounted in the railway wagon is shown herein. The fixing bracket 5 can be installed at a proper position of the railway wagon, for example, the temperature measuring device can be arranged close to the non-heat-resistant parts on the railway wagon, the non-heat-resistant parts of the railway wagon usually comprise a brake valve, a bogie rubber part and the like, and the temperature measuring device can be installed close to the parts, for example, the temperature measuring device is installed on a brake pipe close to the brake valve or a car body close to the bogie rubber, so that the temperature measuring device can accurately detect the temperature of the environment where the non-heat-resistant parts are located.

Of course, the installation position of the temperature measuring device is selected mainly according to the arrangement of parts on the railway wagon, and the normal work of other parts on the railway wagon is not influenced.

In one example, the fixing bracket 5 is mounted on a brake pipe of a railway wagon, and accordingly, the fixing bracket 5 is provided with a mounting hole 5a, the mounting hole 5a is matched with the brake pipe to be fixedly mounted, and a part of a pipe section of the brake pipe is positioned inside the mounting hole 5 a. Of course, the fixing bracket 5 is not limited to be mounted on the brake pipe, and may be mounted on other positions of the car body, for example, the fixing bracket 5 is provided with a threaded hole or a screw hole, and is fixedly connected to the car body of the railway wagon through a bolt or a screw.

The fixing support 5 of the present invention is further provided with a temperature sensing component, the temperature sensing component includes a temperature sensing material, the temperature sensing material is configured to have at least a state corresponding to one temperature threshold, that is, the temperature sensing material may have one or two or more different states, respectively corresponding to different temperature thresholds.

Therefore, through different states of the temperature sensing material, an operator can know the ambient temperature of the railway wagon in the current state, and the service life of the non-heat-resistant part of the vehicle is prevented from being influenced by overhigh thawing temperature. The invention displays the environmental temperature through the temperature sensing material, the use temperature of the temperature sensing material is not limited, and the cost is low.

In the first embodiment, the temperature sensing material may include the temperature sensing sticker 1, the temperature sensing sticker 1 is provided with at least display sections corresponding to two temperature thresholds, and when the ambient temperature is higher than the nth temperature threshold, the color of the display section corresponding to the nth temperature threshold changes to a predetermined color. That is, the temperature sensitive sticker 1 includes N display sections, each of which corresponds to one temperature threshold value, and the temperature threshold values are gradually increased along the arrangement direction of the display sections. For example: the temperature sensing sticker 1 includes 3 display sections: the temperature control device comprises a first display interval, a second display interval and a third display interval, wherein the first display interval corresponds to a first temperature threshold value, the second display interval corresponds to a second temperature threshold value, the third display interval corresponds to a third temperature threshold value, the first temperature threshold value is smaller than the second temperature threshold value, the second temperature threshold value is smaller than the third temperature threshold value, and when the color of the first display interval is displayed as a preset color and the colors of other display intervals are not changed, the current environment temperature is within the range of the first temperature threshold value. When the color of the second display interval is displayed as the preset color and the color of the third display interval is not changed, the environment temperature is within the second temperature threshold range at the moment, and when the colors of the first display interval to the third display interval are all changed, the environment temperature is within the third temperature threshold range at the moment.

The operator can judge the ambient temperature at this time by the display state of the temperature sensing sticker 1, and perform corresponding operation to avoid the over-high ambient temperature of the vehicle due to thawing, and the temperature sensing sticker 1 is cheap and has low replacement cost.

In order to protect the temperature sensing sticker 1, the temperature measuring device can further comprise a heat conducting plate 2 and a protective cover, the heat conducting plate 2 is fixed on the fixing support 5, the protective cover is installed on the heat conducting plate 2, a sealing cavity is formed between the heat conducting plate 2 and the protective cover, the temperature sensing sticker 1 is located in the sealing cavity and attached to the surface of the heat conducting plate 2, and the protective cover at least faces the position, facing the temperature sensing sticker 1, of the transparent material.

The sealed cavity that visor and heat-conducting plate 2 formed plays the guard action to temperature sensing sticker 1, avoids temperature sensing sticker 1 to be destroyed. The transparent material of the protective cover 4 forms a transparent window, and an operator can observe the state change condition of the temperature sensing sticker 1 in the sealing cavity through the transparent window so as to know the current environmental temperature.
