Description

Intelligent temperature transmitter

Technical Field

The invention relates to the technical field of temperature transmitters, in particular to an intelligent temperature transmitter.

Background

The temperature transmitter adopts a thermocouple and a thermal resistor as temperature measuring elements, signals output by the temperature measuring elements are sent to a transmitter module, and are converted into 4-20 mA current signals 0-5V/0-10V voltage signals which are in linear relation with temperature after being processed by circuits such as voltage stabilizing filtering, operational amplification, nonlinear correction, V/I conversion, constant current and reverse protection, and RS485 digital signals are output.

The existing temperature transmitter comprises a shell, a sensor fixedly arranged on the shell and a transmitter body which is arranged inside the shell and electrically connected with the sensor. When temperature transmitter detects the detection liquid of some high temperatures at the in-process of using, detect on the high temperature on the liquid can pass through sensor conduction entering casing inside the changer body to cause the damage of changer body. The conventional temperature transmitter cannot block or radiate the temperature conducted on the sensor, so that the service life of the temperature transmitter is influenced.

Disclosure of Invention

The invention aims to provide an intelligent temperature transmitter which can well cool the temperature on a sensor, so that the service life of the intelligent temperature transmitter is prolonged.

The technical purpose of the invention is realized by the following technical scheme: the utility model provides an intelligence temperature transmitter, includes the casing, sets up in the sensor of casing and sets up in the inside changer body that just is connected with the sensor electricity of casing, the cover is equipped with the fixed pipe that is fixed in the casing on the sensor, it has a plurality of fin to distribute on the sensor, fixed pipe is last to rotate to be provided with and carries out radiating fan blade to the fin, be equipped with the drive component on the fixed pipe, be connected with between drive component and the fan blade and make the drive component can drive the fan blade and carry out pivoted linkage subassembly.

Through adopting above-mentioned technical scheme, during the detection, the temperature conduction on the sensor to the fin, through the fin increase with the area of contact between the air to once dispel the heat to the sensor.

Through adopting above-mentioned technical scheme, the driving gear drives driven gear and rotates, and driven gear drives the fan blade through second linkage and rotates to make the fan blade in the rotation can not receive driven gear to interfere under the effect of second linkage, just so make one-way drive assembly can drive the rotation of fan blade continuation, carry out better heat dissipation to the fin.

Further setting the following steps: the one-way driving assembly comprises a push rod, a rotating block, a spring and a first one-way bearing, wherein the push rod is arranged on the mounting frame along the length direction of the twist rod in a reciprocating sliding mode, the rotating block is arranged on the push rod and is used for driving the twist rod to rotate along with the push rod, the spring is arranged between the push rod and the mounting frame and is used for driving the push rod to move back to one side of the driving gear, and the first one-way.

Through adopting above-mentioned technical scheme, when artifical promotion push rod moved towards spring one side, driven the fried dough twist pole cisoid through the turning block and rotated, the fried dough twist pole in the rotation drives the driving gear through first one-way bearing and rotates. When the push rod moves back to one side of the spring under the action of the spring, the moving push rod drives the twist rod to rotate reversely through the rotating block, and at the moment, the driving gear idles under the action of the first one-way bearing, so that the reversely-rotating twist rod cannot drive the driving gear to rotate reversely, and smooth forward rotation of the driving gear is guaranteed. Like this, the manual work only need exert the drive power that the driving force just can continuation again cooperate the spring to the push rod and rotate, makes the operation more convenient.

Further setting the following steps: the second linkage part is a second one-way bearing, the second one-way bearing is sleeved on the fixed pipe and is in running fit with the fixed pipe, the inner ring of the second one-way bearing is fixedly connected with the fan blade, and the outer ring of the second one-way bearing is fixedly connected with the driven gear.

By adopting the technical scheme, the driven gear in rotation drives the fan blade to rotate through the second one-way bearing, and when the driven gear is in stagnation or reversely rotates, the fan blade continues to rotate in an idle rotation mode under the action of the second one-way bearing, so that the fan blade can be ensured to rotate continuously in one way to output stable wind power.

Further setting the following steps: the fixed locating lever that is provided with on the mounting bracket, the axis of locating lever is parallel to each other with the length direction of fried dough twist rod, the free end of locating lever is worn to establish into the push rod inside and is slided the cooperation with it, the spring housing locate the locating lever.

Through adopting above-mentioned technical scheme, the setting of locating lever can play further guide effect and enable the better being fixed in mounting bracket of spring to the push rod in the slip, promotes structural strength.

Further setting the following steps: the casing is including main part and the lid portion that has the inner chamber, be equipped with intercommunication inner chamber and external opening on the main part, the changer body set up in the inner chamber, be equipped with the connecting portion of outside extension on the opening, connecting portion and lid portion threaded connection are used for opening and close the opening, the radiating groove of intercommunication inner chamber and external has been seted up on the connecting portion.

Through adopting above-mentioned technical scheme, because the changer body can produce a large amount of heats at the in-process of work, through rotating lid portion, make lid portion keep away from the main part gradually and expose the radiating groove, carry out better heat dissipation, increase of service life to the changer body. When the temperature transmitter does not work, the rotating cover body is close to the main body part and is matched with the main body part to seal the inner cavity, so that dust is prevented from entering the inner cavity and affecting the service life of the transmitter body.

In conclusion, the invention has the following beneficial effects: the intelligent temperature transmitter can well cool the temperature on the sensor, thereby prolonging the service life of the intelligent temperature transmitter.
