Abstract
Description
Technical Field
[0001] The utility model relates to the field of temperature measurement in power supply systems, and particularly to an anti-vibration temperature measurement device. Background Art
[0002] With the continuous improvement of the automation level of power systems, the operation safety and reliability of electrical equipment have become particularly important. As one of the key components in power systems, the temperature state of electrical contacts directly affects the stability and safety of the entire system. Traditional temperature monitoring methods often rely on manual regular inspections, which are not only inefficient but also pose safety hazards. In recent years, with the development of wireless sensing technology and Internet of Things technology, wireless temperature sensors have been widely used in the real-time temperature monitoring of electrical contacts to effectively monitor the operation status of electrical equipment.
[0003] However, in practical applications, the environment where electrical contacts are located is often complex and changeable. Especially for equipment such as high-voltage switch cabinets and transformers, these devices may suffer from varying degrees of mechanical vibration and shock during operation. These factors will directly affect the normal operation of wireless temperature sensors. For example, the sensor may be displaced or the connection may become loose due to vibration, resulting in inaccurate measurement data or even damage to the sensor.
[0004] Most of the existing temperature monitoring devices do not take into account these harsh working conditions, and their structural designs are often relatively simple and unable to effectively resist external impacts and vibrations. Therefore, developing an anti-vibration temperature measurement device that can effectively resist vibration and shock is of great significance for ensuring the stable operation of power systems. Summary of the Utility Model

[0006] The technical solution adopted by the utility model to solve its technical problems is: providing an anti-vibration temperature measurement device, including a watchband, a watch case, and a wireless temperature sensor; the watch case includes a housing and an end cover; an accommodation cavity is provided inside the watch case; the accommodation cavity is composed of two active plates, two driven plates, and four arc-shaped plates; two hollow cylindrical parts are respectively provided on two opposite side walls inside the watch case; elastic parts are provided on one side of the two active plates; the active plates are fixedly connected to the side wall of the watch case by extending into the hollow cylindrical parts through the elastic parts; grooves are provided at both ends of the two active plates and the two driven plates; arc-shaped elastic parts are provided on two cross-sections of the arc-shaped plates; the four arc-shaped plates are fixedly connected to the bottom of the grooves at both ends of the two active plates and the two driven plates by extending into the grooves through the arc-shaped elastic parts; the wireless temperature sensor is installed in the accommodation cavity.
[0007] Further, rubber layers are provided on the sides of the active plate, the driven plate and the temperature sensor where they are clamped together.
[0008] Further, a hinge is provided at the connection between the end cover and the housing; corresponding magnetic attraction parts are provided at the connection between the end cover and the housing.
[0009] Further, the watch band includes a first end fixed to the watch case and an opposite second end; a length adjustment member for connecting to the second section of the watch band is provided at the first end of the watch band; circular holes are provided at intervals at the second end of the watch band.
[0010] Further, a clamping member for restricting the watch band is also provided at the second end of the watch band.
[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0012] (1) By providing an active plate, a driven plate and an arc-shaped plate, and using an elastic part and an arc-shaped elastic part, the present utility model forms a multi-layer shock-proof structure, which can effectively absorb and disperse the influence of external vibrations on the wireless temperature sensor. The designs of the elastic part and the arc-shaped elastic part enable the device to relieve the impact force through elastic deformation when being impacted, avoiding directly transmitting it to the wireless temperature sensor, thus greatly reducing the risk of damage to the sensor.
[0013] (2) Due to the adoption of effective shock-proof measures in the present utility model, even in strenuous exercise or complex environments, the wireless temperature sensor can maintain a stable position and state, ensuring the accuracy of temperature measurement. The rubber layers on the active plate and the driven plate further enhance the sealing and shock-proof properties of the device, helping to isolate external interference and ensuring a stable working environment for the temperature sensor.
[0014] (3) The designs of the hinge and the magnetic attraction parts between the end cover and the housing of the present utility model provide a convenient way to open and close, facilitating users to replace and maintain the wireless temperature sensor. Through the above multi-layer shock-proof structure and material selection, the service life of the wireless temperature sensor is extended, and the maintenance and replacement costs are reduced.

[0019] Embodiment:
[0020] A vibration-proof temperature measuring device, as Figure 1 and Figure 2 shown, includes a watch band 1, a watch case 2 and a wireless temperature sensor 3; the wireless temperature sensor 3 is installed in the accommodation cavity 6 inside the watch case, and is used to measure the temperature of the electrical contact point and send the temperature data wirelessly; the accommodation cavity 6 is composed of two active plates 7, two driven plates 8 and four arc plates 9, forming a vibration-proof protection structure to ensure that the wireless temperature sensor can remain stable when encountering external impacts or vibrations.
[0021] Vibration-proof structure: An elastic part 11 is provided on one side of each active plate 7, and the elastic part extends into the hollow cylindrical part 10 to be fixedly connected to the side wall of the watch case; the driven plate 8 and the active plate 7 jointly form the frame of the accommodation cavity, and grooves 12 are provided at both ends of the driven plate 8 and the active plate 7; the arc plate 9 is fixedly connected to the bottom of the groove 12 through the arc elastic part 13 extending into the grooves 12 at both ends of the active plate and the driven plate, forming a closed vibration-proof structure; a rubber layer 14 is arranged on the sides of the active plate 7 and the driven plate 8 that clamp the wireless temperature sensor 3 to increase the damping effect.
[0022] The watchband 1 is used to fix the temperature measuring device near the electrical contact point to ensure that the device stably contacts the object to be measured. The watchband includes a first end 17 of the watchband fixed to the watch case and an opposite second end 18 of the watchband; a length adjusting member 21 connected to the second end 18 of the watchband is provided at the first end 17 of the watchband, which can be adjusted according to the actual position of the electrical contact point to adapt to different installation environments. Circular holes 19 are provided at intervals at the second end 18 of the watchband for cooperating with the first end of the watchband to fix the watchband by inserting a buckle or the like; a clamping member 20 is provided at the second end 18 of the watchband for restricting the watchband to ensure that the device is firmly fixed on the electrical contact point.
[0023] The watch case 2 includes a case body 4 and an end cover 5, which are used to protect the internal components from the external environment; the case body 4 provides a closed outer shell for accommodating the wireless temperature sensor and other internal components; the end cover 5 is connected to the case body through a hinge member 15 to facilitate opening and closing of the watch case.
