Abstract
The utility model discloses an automatic but compress tightly sensor that dry combustion method is prevented simultaneously to outer tube and temperature measurement, including the temperature sensor probe, the heat conduction outer tube that the probe surface cover was equipped with and popped one's head in and laminate, this outer tube front end and probe front end parallel and level, the outer tube is used for detecting and exports temperature signal and give outside temperature controller, this probe is used for detecting the temperature with the outer tube front end, both heat transfer rate are unanimous basically, if high temperature and make the probe damage, the accessible sets up the temperature controller at the outer tube lateral surface and comes as reserve, when the temperature surpasss temperature controller to set the temperature limit value, the dry combustion method procedure is prevented in temperature controller transmission signal and start -up, temperature sensor accessible time and accurately feeds back temperature signal.
Description
Technical field
This utility model relates to temperature detection field, particularly a kind of automatic impaction trocar sheath and can holding concurrently the sensor of anti-dry by thermometric.
Background technology
Temperature sensor is widely used in temperature detection field, internal probe is often burnt out when the ambient temperature used is too high or accelerates the aging of probe by temperature sensor on the market, if the probe of temperature sensor damages, it is continuing with this temperature sensor and can cause that temperature data cannot be timely fed back in control system, and then cause incalculable consequence.
Summary of the invention
For solving above-mentioned technical problem, the purpose of this utility model is to provide a kind of trocar sheath being provided with automatic impaction and this trocar sheath and can hold concurrently the sensor of anti-dry by thermometric.
The technical solution adopted in the utility model is:
A kind of automatic impaction trocar sheath and can holding concurrently the sensor of anti-dry by thermometric, including a temperature sensor probe, described detecting head surface is arranged with and the heat conduction trocar sheath of laminating of popping one's head in, and this trocar sheath front end is concordant with probe distal end, and this trocar sheath gives outside temperature controller for detection output temperature signal;Also include a Radix Rumicis screw, the afterbody of described probe is arranged with an annulus, described trocar sheath is convex shape, with probe laminating inside the ledge of this trocar sheath, inside this annulus and trocar sheath rear section, laminating and annulus front end are stuck in the tail end of trocar sheath ledge, this Radix Rumicis screw is connected by the female thread of external screw thread with trocar sheath tail end, and the front end of this Radix Rumicis screw is pressed on the tail end of annulus.
Described trocar sheath is Cu jacket pipe or alloy trocar sheath.
In the middle of described Radix Rumicis screw, perforation and this hole are for wearing the electric wire connecting probe.
Described temperature controller is arranged on the lateral surface of trocar sheath rear section.
The lateral surface of described trocar sheath ledge is additionally provided with for connecting by the screw thread of temperature measuring equipment.
The beneficial effects of the utility model:
This utility model temperature sensor, it is arranged with and the heat conduction trocar sheath of temperature sensor probe laminating, probe distal end is concordant with trocar sheath front end, probe is basically identical with the heat transfer rate of trocar sheath, it is arranged on the stand-by provision as thermometric of the temperature controller on trocar sheath, if tip damage, in the environment that temperature is too high, hotness is sent to temperature controller by trocar sheath, beyond temperature controller set limit temperature value time, temperature controller transmission signal enabling anti-dry program, this novel temperature sensor can timely and accurately feedback temperature signal.

Detailed description of the invention
As it is shown in figure 1, this utility model temperature sensor, including a temperature sensor probe 1.
Common temperature sensor is when detecting temperature, if detection ambient temperature is too high, probe 1 is easily burned, and for this, following improvement is made in this utility model temperature sensor:
As shown in figs 2-4, 1 surface of popping one's head in is arranged with and the heat conduction trocar sheath 2 of 1 laminating of popping one's head in, heat conduction trocar sheath 2 embodiment herein selects Cu jacket pipe, alloy trocar sheath can also be selected, this trocar sheath 2 front end is concordant with probe 1 front end, this trocar sheath 2 gives outside temperature controller 3 for detection output temperature signal, owing to trocar sheath 2 front end is concordant with probe 1 front end, heat transmission speed on body 1 and on trocar sheath 2 is basically identical, the afterbody of probe 1 is arranged with an annulus 11, described trocar sheath 2 is convex shape, with probe 1 laminating inside the ledge of this trocar sheath 2, inside this annulus 11 and trocar sheath 2 rear section, laminating and annulus 11 front end are stuck in the tail end of trocar sheath 2 ledge, this temperature sensor also includes a Radix Rumicis screw 4, this Radix Rumicis screw 4 is connected by the female thread of external screw thread with trocar sheath 2 tail end, the front end of this Radix Rumicis screw 4 is pressed on the tail end of annulus 11, in the middle of Radix Rumicis screw 4, perforation and this hole are for wearing the electric wire connecting probe 1, temperature sensor detection temperature, and temperature data is transferred in control system.
Described temperature controller 3 is arranged on the lateral surface of trocar sheath 2 rear section, when probe 1 damage, in the environment that temperature is too high, hotness is sent to temperature controller 3 by trocar sheath 2, beyond temperature controller 3 set limit temperature value time, temperature controller 3 transmits signal enabling anti-dry program, and the design can timely and accurately feedback temperature signal.
It addition, the lateral surface of trocar sheath 2 ledge is additionally provided with for connecting by the screw thread 21 of temperature measuring equipment, can be used for being fixed on by the device of thermometric.
The foregoing is only preferred embodiments of the present utility model, this utility model is not limited to above-mentioned embodiment, broadly falls within protection domain of the present utility model as long as realizing the technical scheme of this utility model purpose with essentially identical means.
