Detailed Description

In order to make the technical solutions of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a temperature measuring device according to an embodiment of the present invention;

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 temperature sensor, a controller 1 and a heat insulation shell 4.

The temperature measuring device can be arranged at a proper position of the unfreezing warehouse and also can be arranged at a proper position of the railway wagon, and the technical scheme and the technical effect are described by taking the temperature measuring device arranged on the railway wagon as an example. The temperature measuring device can be installed at a proper position of the railway wagon, for example, the temperature sensor 5 of the temperature measuring device can be arranged close to the non-heat-resistant part on the railway wagon, the non-heat-resistant part of the railway wagon usually comprises 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 part is 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 temperature measuring device can be mounted on a brake pipe of a railway wagon, and accordingly, the temperature measuring device is provided with a mounting hole which is matched with the brake pipe to be fixedly mounted, and a part of a pipe section of the brake pipe is located inside the mounting hole. Of course, the temperature measuring device is not limited to be mounted on the brake pipe, and may be mounted at other positions of the vehicle body.

The controller 1 is arranged inside the heat insulation shell 4, the temperature sensor 5 is positioned outside the heat insulation shell 4, and the temperature sensor 5 can detect the external environment temperature. The temperature sensor 5 is electrically connected with the controller 1, so that the temperature signal retrieved by the temperature sensor 5 is transmitted to the controller 1, the controller 1 further transmits a transmission component connected with the controller 1, the transmission component may be a wireless transmission component, such as a bluetooth component 7, and of course, the transmission component may also be other high temperature resistant wired transmission components, so as to transmit the temperature collected by the temperature sensor 5, which is processed and stored by the controller 1, to an external device. Therefore, an operator can know the ambient temperature of the railway wagon in the current state through the temperature displayed by the external equipment, and the service life of the non-heat-resistant part of the wagon is prevented from being influenced by overhigh thawing temperature.

Of course, the transmission component can also transmit external instructions to the controller.

The material of the heat insulation shell 4 can be glass fiber board, and of course, the material with good heat insulation effect, such as foam material, etc., can also be used.

In one example, in order to further insulate the heat of the external environment, the inside of the thermal insulation casing 4 is further filled with the thermal insulation material layer 3, and the thickness of the thermal insulation material layer 3 ranges from about 20mm to 60mm, that is, the thickness of the thermal insulation material layer 3 can range from any value between 20mm to 60 mm. In a particular embodiment, the thickness of the insulating material layer 3 may be greater than 40 mm. The thickness of the heat insulating material layer 3 within this range can realize that the internal temperature rise is not more than 85 ℃ after 150min when the external temperature is 150 ℃.

The heat insulating material can be silicon dioxide nano aerosol, and can also be foam material or fiber material.

The number of temperature sensors 5 in the above-described embodiments may be determined according to the specific circumstances, and a transmission line connected between the temperature sensors 5 and the controller 1 may be passed through the heat insulating housing 4 at an appropriate position.

In this embodiment, the temperature measuring device further includes a temperature switch 6 located outside the heat insulation casing 4, and the temperature switch 6 may be fixed on the outer wall of the heat insulation casing 4, or may be installed in the external environment. The temperature switch 6 can measure the temperature of the external environment and control the operating state of the controller 1 according to the external environment temperature. For example, the temperature switch 6 may turn on the controller 1 when the temperature switch 6 detects that the temperature reaches a predetermined temperature, otherwise the controller 1 is in a non-on state. This can save power consumption of the controller 1 considerably.

The temperature at which the temperature switch 6 controls the controller 1 to be turned on may be preset, for example, in an example, when the temperature switch 6 detects that the external environment temperature is relatively low, for example, lower than 50 degrees celsius, at this time, each electronic component in the temperature measuring device can safely operate under this temperature condition, the controller 1 does not need to record the temperature, and the controller 1 may be in a sleep state or a power-off state. When the temperature switch 6 detects that the temperature exceeds the preset temperature, the temperature switch 6 controls the controller 1 to be in an open state.

The temperature measuring device in this embodiment further includes a clock unit 8 and a memory 9, and the memory 9 stores preset conditions for the controller 1 to start the measurement operation, and stores the temperature of the temperature sensor and a clock signal corresponding to the temperature. The preset condition is set in advance manually, and the preset condition may include a season period, for example, when the memory 9 judges that summer is present, the controller 1 does not start the measurement even if the temperature switch 6 detects a temperature higher than the preset temperature. Only when the memory 9 judges that the environmental throttle is in the season needing thawing, the controller 1 starts the measurement operation, so that the power consumption of the system can be reduced, and the service life of the battery module can be prolonged.

The clock unit 8 is used for real-time control of the scheduled operating time. This allows for the recording of temperature and time to occur while monitoring the temperature under thawing conditions to facilitate the supervision of thawing bank violations.

In this embodiment, the temperature switch 6 may be electrically connected to the controller 1 through a high temperature cable, and the heat-resistant temperature of the high temperature cable is higher than 200 degrees celsius. Accordingly, the insulation casing 4 and the insulation material layer 3 may be provided with a penetration opening 41 for the penetration of the high temperature cable.

In the above embodiment, the temperature measuring device may further include a battery module located inside the heat insulation casing 4, and the battery module is used for supplying power to the controller 1. The battery module can supply power to the controller 1 unit, and the battery module is positioned inside the heat insulation shell 4, and the safe working temperature of the battery module is ensured by utilizing the heat insulation shell 4.

In order to improve the installation reliability of the temperature measuring device, the temperature measuring device further comprises a metal mounting plate 2 fixed with the heat insulation shell 4, and a mounting structure is arranged on the metal mounting plate 2 and used for being fixedly installed with the external environment. The mounting structure may be a threaded hole or a bolt hole.

The invention also provides a railway wagon, which comprises a wagon body and any one of the temperature measuring devices, wherein the temperature sensor 5 of the temperature measuring device is close to the brake pipe of the brake valve or the wagon body position of the bogie rubber part.
