Abstract
The utility model discloses a temperature sensor comprising a sensor body and a detection head which is arranged at one side of the sensor body. A positioning device is arranged at the other side of the sensor body and comprises a supporting tube, an expansion link, a compression spring and an attached block, wherein one end of the supporting tube is fixedly connected with the sensor body; one end of the expansion link is threadedly connected in the supporting tube; the other end of the expansion link is connected with the compression spring; and the attached block is fixedly connected at the other end of the compression spring. The temperature sensor has the advantages of convenient installation and accurate sensing of the temperature rise of a busbar.
Description
Technical field
The utility model relates to a kind of pick-up unit, is specifically related to a kind of contactless temperature sensor.
Background technology
Regulation will be strengthened the supervision to the operational outfit temperature rise in State Grid's grid company " 18 great anti-accident measures of electrical network ", and common this supervision is finished by sensor.Can be used on the market at present realize that the sensor of above-mentioned functions also has a lot of shortcomings when realizing monitoring function, the product that can be used to monitor temperature rise exists more installs inconvenient part, if and adopt mode such as infrared to supervise side, very high to the requirement of installing, the installation inconvenience that causes equipment, adopt communication products such as optical fiber, when many cabinets link, can produce the phase mutual interference, also can cause measuring inaccurate.
Summary of the invention
The utility model is at the shortcoming of prior art, and purpose is to provide a kind of convenient temperature sensor of installing, also accurately responding to busbar temperature rise situation.
The technical scheme that realizes the utility model purpose is as follows:
Temperature sensor, the detection head that comprises sensor main body and be arranged at sensor main body one side, described sensor main body opposite side is provided with locating device, this locating device comprises stay pipe, expansion link, compression spring and attachment piece, one end of stay pipe is fixedlyed connected with sensor main body, the threaded one end of expansion link is connected in the stay pipe, and the other end of expansion link connects compression spring, and attachment piece is fixedly connected on the other end of compression spring.
Nut has been threaded on the described expansion link.
The end face of described attachment piece is provided with some teeth that rub that increase.
Adopted such scheme, an end of stay pipe is fixedlyed connected with sensor main body, and the threaded one end of expansion link is connected in the stay pipe, and the other end of expansion link connects compression spring, and attachment piece is fixedly connected on the other end of compression spring.By expansion link compression spring is exerted pressure, attachment piece is close proximity on the contact wall, contact wall produces opposition and acts on the whole sensor, and sensor can directly contact the contact wall of busbar by the detection head on it, thereby guarantees the accuracy of measurement result.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
In the accompanying drawing, 1 is sensor main body, and 2 is detection head, and 3 is stay pipe, and 4 is expansion link, and 5 is compression spring, and 6 is attachment piece, and 7 is nut, and 8 for increasing the tooth that rubs.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
With reference to Fig. 1, temperature sensor of the present utility model, sensor main body 1 inside is provided with circuit, the detection head 2 of one side of sensor main body 1, sensor main body 1 opposite side is provided with locating device. and locating device comprises stay pipe 3, expansion link 4, compression spring 5 and attachment piece 6, one end of stay pipe 3 is fixedlyed connected with sensor main body, the threaded one end of expansion link is connected in the stay pipe, the other end of expansion link connects the other end that nut 7. attachment pieces 6 that are threaded on compression spring 5. expansion links 4 are fixedly connected on compression spring 5, and the end face of attachment piece 6 is provided with some teeth 8. that rub that increase
During use,, adjust the position that is threaded of expansion link 4 and stay pipe, make the attachment piece 6 that is connected on the expansion link 4 have the end face that increases the tooth that rubs and closely contact with contact wall according to the size of busbar bore.Adjust the further spacing expansion link in position of nut and the link position of stay pipe, attachment piece is closely contacted with contact wall.
