Description

Technical Field

[0001] The utility model relates to the technical field of temperature detection, in particular to a contact type temperature measuring device inside a switch cabinet. Background Art

[0002] In the power system, as one of the key devices, the operating state of the electrical components inside the switch cabinet is directly related to the safety and stability of the entire power system. Especially for the joint part inside the switch cabinet, due to long-term exposure to large current and high voltage, it is prone to overheating, which may further lead to faults or even accidents. Therefore, it is necessary to monitor its temperature. Among them, the contact type wireless temperature monitoring device is a commonly used monitoring device. It uses a wireless temperature sensor to contact the device to be detected, and monitors and transmits it to the terminal for analysis and processing in real time through the wireless temperature sensor.

[0003] However, in order to fix the traditional wireless temperature sensor to the detection point, it is usually integrated with a cable tie or a clamp and directly fixed on the device to be detected. When maintaining the wireless temperature sensor inside it, it is necessary to remove it as a whole for operation, and then fix it again through a cable tie or a clamp, which is rather troublesome. Regular maintenance of the wireless temperature sensor is the key to ensuring its normal operation and accurate measurement. Therefore, we propose a contact type temperature measuring device inside a switch cabinet to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the defect that the wireless temperature sensor directly fixed integrally with a cable tie or a clamp in the prior art is troublesome to disassemble during maintenance, and to propose a contact type temperature measuring device inside a switch cabinet.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A contact type temperature measuring device inside a switch cabinet includes a switch cabinet. An installation plate is fixedly arranged inside the switch cabinet. A wireless receiver is fixedly arranged on one side of the installation plate. A device to be detected is arranged on one side of the installation plate. A plurality of joints to be detected are arranged on the device to be detected, and temperature measuring components are arranged on the plurality of joints to be detected;

[0007] Among them, the temperature measuring component includes a protection box. A through hole is formed in the protection box, and the aperture of one side is smaller than that of the other side. A wireless temperature sensor is arranged inside the protection box, and the contact end of the wireless temperature sensor passes through the side with a smaller aperture and extends to the outside;

[0008] The wireless temperature sensor is electrically connected to the wireless receiver;

[0009] Fixing component, which is arranged on the protection box and is used for fixing between the temperature measurement component and the joint to be detected;

[0010] Limiting component, which is arranged on one side of the protection box and is used for the temperature measurement contact of the wireless temperature sensor to stably contact the joint to be detected.

[0011] In a possible design, the fixing component includes two fixing blocks, which are respectively and fixedly arranged on two opposite sides of the protection box. Threaded holes are formed in both fixing blocks, and fixing bolts are threadedly connected in both threaded holes. The same fixing plate is threadedly connected through both fixing bolts.

[0012] In a possible design, the surface of the protection box close to the side with a larger aperture is provided with threads and threadedly connected with a thread cover, which is convenient for taking out the wireless temperature sensor for maintenance.

[0013] In a possible design, the limiting component includes a rotating plate. One side of the rotating plate is rotatably connected to the inner wall of one side of the thread cover. Two compression springs are symmetrically and fixedly connected to the other side of the rotating plate. One end of each of the two compression springs is fixedly provided with a push plate, and one side of the push plate abuts against the wireless temperature sensor.

[0014] In a possible design, heat dissipation holes for heat dissipation are formed in both the top and bottom of the protection box.

[0015] In a possible design, a spring piece is fixedly arranged on the side of the fixing plate close to the protection box and is used for fixing with contact points of different shapes.

[0016] In this application, first, place the protection box of the temperature measurement component on one side of the point to be detected, and then threadedly connect the fixing bolts thereon with the fixing plate located on the other side of the point to be detected, so as to fix between the temperature measurement component and the point to be detected. The spring piece arranged on the fixing plate supports the detection point, so that contact points of different shapes can be fixed. Then, put the wireless temperature sensor into the protection box, make the contact end of the wireless temperature sensor contact the joint to be detected, and then screw on the thread cover.

[0017] During the process of tightening the thread cover, the push plate inside the thread cover will move towards the side of the wireless temperature sensor until it contacts the surface of one side of the wireless temperature sensor. The rotating plate rotatably connected to the thread cover is connected to the push plate through the compression spring, that is, it prevents the rotation of the push plate during the movement and provides the driving force for the push plate. At the same time, the elastic force of the compression spring can not only make the contact end of the wireless temperature sensor stably contact the joint to be detected but also prevent damage caused by excessive extrusion.

[0018] The wireless temperature sensor collects the temperature data of the joint to be detected in real time and transmits the data to the wireless receiver on the mounting plate wirelessly. After receiving the data, the wireless receiver can further transmit the data to the monitoring center for processing and analysis in a wired or wireless manner.

[0019] When maintenance or replacement of the wireless temperature sensor is required, simply unscrew the threaded cover on the protective box to easily remove the sensor for operation, which is simple and fast.

[0020] Beneficial effects:

[0021] In the present utility model, for the internal contact temperature measuring device of the switch cabinet, the wireless temperature sensor directly contacts the joint to be detected, reducing the intermediate links and improving the temperature measurement accuracy.

[0022] In the present utility model, for the internal contact temperature measuring device of the switch cabinet, the fixing component facilitates the installation of the device. At the same time, the threaded cover on the protective box is designed such that the wireless temperature sensor can be conveniently taken out for maintenance or replacement.

[0023] In the present utility model, for the internal contact temperature measuring device of the switch cabinet, through the design of the limiting component, stable contact between the temperature measuring component and the joint to be detected can be ensured. At the same time, the design of the spring piece on the fixing plate enables the device to adapt to contact points of different shapes, improving the adaptability and stability of the device.

A wireless receiver 3 is fixedly installed on one side of the mounting plate 2 for receiving temperature measurement data. The device to be detected 4 is arranged on one side of the mounting plate 2, and a plurality of joints to be detected 5 are arranged on the mounting plate 2.

[0033] A temperature measuring component 6 is installed on each joint 5 to be detected. The core component of the temperature measuring component 6 is a protective box 7. The protective box 7 is designed as a structure with different aperture sizes on both sides. One side has a smaller aperture for the contact end of the wireless temperature sensor 8 to extend out to ensure close contact with the joint 5 to be detected. The wireless temperature sensor 8 is installed inside the protective box 7 and is connected to the wireless receiver 3 through an electrical connection to realize wireless transmission of temperature measurement data.

[0034] In order to ensure a stable connection between the temperature measuring component 6 and the joint to be detected 5, the present embodiment adopts a fixing component, which includes two fixing blocks 9, which are respectively fixed on both sides of the protective box 7 and cooperate with the fixing bolts 10 through threaded holes. The two fixing bolts 10 then pass through and are threadedly connected to the fixing plate 11, thereby firmly fixing the temperature measuring component 6 on the joint to be detected 5.

[0035] In addition, in order to facilitate the maintenance and replacement of the wireless temperature sensor 8, the protective box 7 is provided with a thread on the surface of the side close to the large aperture, and is threadedly connected with a threaded cover 12. The protective box 7 can be easily opened or closed by rotating the threaded cover 12.

[0036] To improve the stability of the temperature measurement contact point, a limit component is further added.
