Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.

As shown in fig. 1 and 2, a temperature sensor comprises a tip 1, a temperature sensing element 2 arranged at the lower part of the tip 1, and a telescopic device, wherein the telescopic device comprises a housing 4, an automatic telescopic mechanism arranged in the housing 4, and a pulling rope, one end of the pulling rope is arranged on the tip 1, the other end of the pulling rope is arranged on the automatic telescopic mechanism, and connecting pieces are correspondingly arranged on the housing 4 and the tip 1; the lower part of the end head 1 is also provided with a buoyancy ring 3.

Under normal conditions, the telescopic equipment is arranged integrally with the end head 1 through the connecting piece, and is convenient to store and transport. During the use, fix casing 4 on the container wall through the connecting piece, temperature sensor floats on the liquid level through the effect of buoyancy circle 3, and the haulage rope lengthens under temperature sensor's action of gravity when the liquid level descends, and the haulage rope contracts under automatic telescopic machanism's effect when the liquid level rises, can pull back temperature sensor convenient to use through the haulage rope when needing to maintain temperature sensor. The buoyancy ring 3 is arranged in a hollow way, and air is filled in the buoyancy ring. In this embodiment, the connecting piece is a hook, the hook is arranged on the shell 4, and a hook groove is arranged on the end 1 corresponding to the hook. When in use, the shell 4 can be hung on the container wall through the hook. In other embodiments, the connecting piece is a sucker, the sucker is arranged on the shell 4, and the end head 1 is provided with a plane adsorption position corresponding to the sucker.

In this embodiment, a partition plate 8 for dividing the space in the housing 4 into two chambers is disposed in the housing 4, a through hole is disposed on the partition plate 8, the automatic telescopic mechanism includes a rotating shaft 7 and a coil spring 9, the rotating shaft 7 is inserted into the through hole, and both ends of the rotating shaft are rotatably disposed on the housing 4, the coil spring 9 is disposed in one chamber, one end of the coil spring is fixed on the housing 4, and the other end of the coil spring 9 is disposed on the rotating shaft 7; the pulling rope is wound in the other cavity, and the other end of the pulling rope is arranged on the rotating shaft 7. When the traction rope stretches, the rotating shaft 7 is driven to rotate, and the rotating shaft 7 drives the coil spring 9 to roll. The shell 4 is composed of an upper part and a lower part, the connecting piece is arranged at the bottom of the lower part of the shell, and two ends of the rotating shaft 7 are respectively positioned at two sides of the partition plate 8. When the liquid level rises to lead the haulage rope to shrink, wind spring 9 drives pivot 7 reversal, and pivot 7 is rotatory to make the haulage rope winding shrink on pivot 7.
