Description

Technical Field

[0001] The utility model relates to the technical field of bimetallic thermometers, in particular to a lifting and lowering regulating bimetallic thermometer. Background Art

[0002] Bimetallic thermometer is a field detection instrument for measuring medium and low temperatures. It can directly measure the temperature of liquid, steam and gas medium in the range of -80℃ to +500℃ in various production processes. The main component of industrial bimetallic thermometer is a multi-layer metal sheet composed of two or more metal sheets laminated together, which works on the principle that two different metals expand to different degrees when the temperature changes. It is based on a bimetallic sheet wound into a ring-shaped bending shape. When one end is heated and expanded, it drives the pointer to rotate, and the working instrument displays the temperature value corresponding to the thermoelectric potential. The existing bimetallic thermometer does not have the function of lifting and lowering adjustment, and cannot be flexibly installed on the pool.

[0003] After searching, China Authorization Announcement No. CN206223309U discloses a lifting and lowering adjustable bimetallic thermometer, including a bimetallic thermometer body, a metal tube is provided at the lower part of the bimetallic thermometer body, a connecting tube is provided at the lower part of the metal tube, and the connecting tube is connected to the metal tube through a butt tube; the lifting and lowering adjustment shaft can be rotated around the guide tube, so as to facilitate the vertical lifting and lowering adjustment of the side plate, and the side plate can be adjusted to a position parallel to the water surface, thereby indirectly adjusting the bimetallic thermometer body; however, the above patent has the following shortcomings: the bimetallic thermometer body needs to be adjusted and raised manually, and it is necessary to pay attention to the water level of the pool at all times, which is inconvenient to adjust. Utility Model Content

[0004] The technical problem to be solved by the utility model is: in order to overcome the above problems, a lifting and lowering regulating bimetallic thermometer is provided, which solves the above problems.

[0005] The utility model solves the technical problem by adopting the following technical solutions:

[0006] A lifting and adjusting bimetallic thermometer comprises a bottom plate fixed to the bottom of a pool, a linear slide rod fixedly arranged on the upper end surface of the bottom plate and a top plate fixedly arranged on the upper end of the linear slide rod, a lifting buoy sliding up and down is arranged in the middle of the top plate, the lifting buoy has no contact with the top plate, two sliding sleeves are fixedly arranged on the side of the lifting buoy and are mounted on the linear slide rod for limiting and guiding the lifting buoy, a bimetallic thermometer is fixedly arranged in the lifting buoy, and a bimetallic thermometer temperature measuring rod contained in the bimetallic thermometer extends downward from the lifting buoy and a sealing ring is fixedly arranged on the extending part for waterproofing, so that the hollow cylinder formed by the lifting buoy has buoyancy so that the bimetallic thermometer is suspended on the water surface, and a thermal insulation lining sleeve is fixedly arranged in the lifting buoy for reducing interference caused by thermal radiation.

[0007] Preferably, a height scale is provided on the outside of the lifting buoy to display the floating height of the lifting buoy, thereby indirectly obtaining the position of the collecting end of the temperature measuring rod of the bimetallic thermometer.

[0008] Preferably, a transparent waterproof cover is installed on the upper port cover of the lifting buoy, which facilitates observation of temperature and prevents water from splashing into the lifting buoy.

[0009] Preferably, combined Figure 4 and five A rotating locking component is also rotatably provided on the upper end surface of the top plate, and the rotating locking component is a rubber disc with a cutout. When the cutout faces the lifting buoy, the rotating locking component does not contact the lifting buoy, so that the lifting buoy can move up and down under the action of buoyancy. When it is desired to lock it at a specified depth, the rotating locking component is rotated to press its side against the side wall of the lifting buoy to limit the up and down floating of the lifting buoy. Of course, this is only an embodiment, and bolts can also be used as substitutes to lock the lifting buoy in the same manner as abutment.

[0010] Preferably, two limiting sleeves are fixedly mounted on the lower end of the linear slide rod, and when the lower end surface of the linear slide rod abuts against the upper end surface of the limiting sleeve, there is a gap between the lower end of the bimetallic thermometer temperature measuring rod and the base plate to prevent the bimetallic thermometer temperature measuring rod from colliding with the base plate and causing damage.

[0011] Preferably, in order to improve the overall safety, a cylindrical protective net is fixed between the bottom plate and the top plate, and the cylindrical protective net is mounted on the outside of the linear sliding rod. The mesh holes on its surface allow water to flow through, so that the bimetallic thermometer temperature measuring rod can collect accurate temperature and provide good protection effect.

[0012] The advantages and positive effects of the utility model are:

[0013] 1. The present application proposes a lifting and adjusting bimetallic thermometer, which can automatically adjust the bimetallic thermometer as the water level changes by installing a structural frame in a water pool and using a lifting buoy to form a floating cylinder. The lifting buoy isolates the water from the head of the bimetallic thermometer to prevent water from entering the head, which is safer and more reasonable.

[0014] 2. The cylindrical protective net can provide a good all-round protection effect for the entire device, avoiding deformation of the bimetallic thermometer due to collision and prolonging its service life. BRIEF DESCRIPTION OF THE DRAWINGS
