Description

[Technical field]

[0001] The utility model relates to an intelligent temperature measuring device based on wireless access. [Background technology]

[0002] At present, wireless temperature sensors are installed on some high-voltage switchgear, knife switches, cables and other products in order to monitor the working temperature of these equipment products, whether there is temperature abnormality, monitor the temperature in real time through the monitoring system and issue an alarm in the event of temperature abnormality. Usually, wireless temperature sensors are installed on the equipment under test through clamps or cable ties, but for some cables, the use of clamps is likely to cause marks on the cable surface, and improper use of force may also cause damage to the cable skin; and when fixing with cable ties, the subsequent disassembly work is very likely to cause damage to the cable skin when the cable ties are damaged, and at present, there is a lack of wireless temperature sensors specifically for cables on the market. [Contents of the utility model]

[0003] The purpose of the utility model is to overcome the above problems. We provide an intelligent temperature measuring device based on wireless access, which is specially used for cable temperature measurement.

[0004] To achieve the above-mentioned purpose, we provide an intelligent temperature measuring device based on wireless access, which includes an elastic clamping part and a shell. The elastic clamping part is in a "C" shape with one end open, and a clamping cavity is formed inside the elastic clamping part. The opening of the elastic clamping part is in a trumpet shape that gradually narrows from the inside to the outside. The shell is fixed on the elastic clamping part and away from the opening.

Brief Description of the Drawings

[0011] Figure 1 This is a structural schematic diagram of an intelligent temperature measuring device installed on a cable in an embodiment of the utility model. [Specific implementation method]

[0012] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0013] Please see Figure 1 The present application provides an intelligent temperature measuring device based on wireless access, which includes an elastic clamping part and a shell 1, wherein the elastic clamping part is in a "C" shape with one end open, and a clamping cavity is formed inside the elastic clamping part, and the clamping cavity is used to clamp the cable. The opening of the elastic clamping part is in a trumpet shape that gradually narrows from the inside to the outside. When installing the elastic clamping part, the user needs to expand the opening by hand. At this time, the elastic clamping part is in a deformed state, and the cable is sent into the clamping cavity. After releasing the hand, the opening returns to its original size, and the elastic clamping part also returns to its original state to clamp the cable. The shell 1 is fixed on the elastic clamping part and away from the opening. An antenna module 2 and a temperature sensing module 3 are arranged in the shell. The temperature sensing module is electrically connected to the antenna module. The temperature sensing module is used to sense the temperature of the cable, and the wireless module is used to transmit the temperature information read by the temperature sensing module to the outside.

[0014] An arc-shaped heat-conducting portion 4 is arranged on the inner side of the elastic clamping portion, and a hole is opened on the elastic clamping portion corresponding to the position of the temperature sensing module 3. The arc-shaped heat-conducting portion 4 has a temperature-conducting portion 41 that passes through the hole and contacts the temperature sensing module. The arc-shaped heat-conducting portion can better contact and conduct heat with the cable, so that the temperature sensing module can read more accurate temperature information.

[0015] The elastic clamping part includes a stainless steel body 5 and an insulating layer 6 wrapped around the stainless steel body. When producing the elastic clamping part, the stainless steel body is firstly stamped and bent into shape, and then subjected to plastic dipping treatment to form an insulating layer on the surface of the stainless steel body.

[0016] The elastic clamping part is provided with a holding part 7 protruding toward the clamping cavity near the opening. The holding part can exert a holding force on the surface of the cable, so that the elastic clamping part clamps the cable more tightly, achieving the advantage of being more secure after installation.

[0017] The antenna module 2 is an RFID antenna module. By using RFID technology, the antenna module can obtain the power required for operation from the received radio frequency signal and supply it to the temperature sensing module. At the same time, it can transmit the temperature information of the temperature sensing module back to the reader that sends the radio frequency signal.

[0018] The opening width of the elastic clamping part accounts for one third of the diameter of the clamping cavity, ensuring that after the elastic clamping part clamps the cable, the cable and the elastic clamping part will not be easily loosened, thereby ensuring that the temperature sensing part can read the temperature of the cable.

[0019] The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment. Any equivalent modifications or changes made by ordinary technicians in this field based on the contents disclosed in the present invention should be included in the protection scope recorded in the claims.
