Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of temperature sensor installation structures, in particular to a temperature sensor installation structure. Background Art
[0002] In industrial production, it is often necessary to use cooling towers for cooling. If the heat exchange efficiency of the materials is low, invalid circulation will occur and the motor will operate ineffectively. To solve this problem, the manufacturer will install a temperature sensor at the outlet of the cold circulation return pipe of the equipment to be cooled, and set the temperature of the temperature controller to a reasonable threshold. When the circulating cooling water temperature is lower than the set threshold, the cooling pump will stop running. If it exceeds the set temperature, the cooling pump will be started again for circulation cooling.
[0003] However, the existing temperature sensor is directly fixed at the outlet of the cold circulation return pipe by threads during installation. Since the probe of the temperature sensor is directly inserted into the cold circulation return pipe, the return water in the cold circulation return pipe flows continuously and repeatedly. The return water will directly impact the probe during the flow, causing the probe to oscillate and deflect. When the oscillation amplitude of the probe is too large, the direct contact heat transfer between the probe surface and the detected temperature medium will become uneven and unstable, thereby affecting the temperature detection accuracy. Therefore, a temperature sensor installation structure is needed to solve the above problems. Utility Model Content

[0008] Preferably, a screw cap is connected to the top end of the threaded shaft, and the screw cap is threadedly sleeved on the outside of the threaded column. The screw cap design at the top end of the threaded shaft makes it convenient for workers to twist the screw cap using tools.

The rubber ring is fitted to the inner wall of the threaded shaft to ensure the sealing of the threaded shaft and the threaded column.
[0010] Preferably, a reinforcement component is movably installed on the surface of the threaded column, and the reinforcement component includes two connecting frames. A right buckle and a left buckle are movably installed at the ends of the connecting frames, which are buckled to the outside of the cold circulation return pipe through the right buckle and the left buckle, and then the threaded column is fixed.

The detection probe can be protected by the protective sleeve to prevent water from directly impacting the detection probe during flow, reduce the probability of oscillation of the detection probe during sensing measurement, and ensure the accuracy of temperature measurement in the cold circulation return pipe.
[0015] By setting up a reinforcement component, the stability of the temperature sensor module installation is ensured. The device rotates and moves the nut on the surface of the threaded column to adjust and change the height of the right buckle ring and the left buckle ring, so that the right buckle ring and the left buckle ring can be buckled around the outside of the cold circulation return pipe.

[0025] A screw cap 32 is connected to the top of the threaded insert shaft 31 , and the screw cap 32 is threadably sleeved on the outside of the threaded column 22 .
[0026] A rubber ring 24 is embedded in the bottom end of the threaded column 22 through a ring groove. The vertical section of the rubber ring 24 consists of a semicircular end and a rectangular end.
[0027] A reinforcement component 4 is movably mounted on the surface of the threaded column 22 . The reinforcement component 4 includes two connecting frames 43 . A right buckle 44 and a left buckle 45 are movably mounted at the ends of the connecting frames 43 .
[0028] The two connecting frames 43 are symmetrically fixed on both sides of the connecting ring 42 . The connecting ring 42 is sleeved on the outside of the nut 41 through an annular groove. The nut 41 is threadedly sleeved on the outside of the threaded column 22 .
[0029] A threaded bayonet 46 is rotatably mounted on the bottom end of the right buckle ring 44 , and the threaded bayonet 46 is embedded in the bottom end of the left buckle ring 45 through a groove, and two fixing screw sleeves 47 are sleeved on the end of the threaded bayonet 46 .
