Description

Technical Field

[0001] The utility model belongs to the technical field of temperature transmitters, and more specifically, particularly relates to an explosion-proof temperature transmitter with a heat dissipation function. Background Art

[0002] The temperature transmitter uses thermocouples and thermal resistors as temperature measuring elements. The output signal from the temperature measuring element is sent to the transmitter module. After being processed by circuits such as voltage stabilization and filtering, operational amplification, nonlinear correction, V / I conversion, constant current and reverse protection, it is converted into a 4-20mA current signal 0-5V / 0-10V voltage signal that is linearly related to the temperature and output through RS485 digital signals.

[0003] When the temperature transmitter is measuring temperature, the temperature of the measured object and the temperature of the internal components during operation are easily accumulated inside the transmitter. Failure to dissipate heat in time will cause damage to the temperature transmitter. Some current explosion-proof temperature transmitters with heat dissipation functions are directly exposed to the air during installation. When there is more moisture in the air or on rainy days, a large amount of moisture enters the temperature transmitter, which can easily cause the temperature transmitter to short-circuit and spontaneously combust, causing a safety accident.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an explosion-proof temperature transmitter with heat dissipation function is provided, in order to achieve a more practical purpose. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides an explosion-proof temperature transmitter with heat dissipation function, which is achieved by the following specific technical means:

[0006] A explosion-proof temperature transmitter with heat dissipation function comprises a transmitter body, a rear baffle is installed on one side of the transmitter body, a temperature sensor is installed on one side of the rear baffle at a position close to the transmitter body, a cooling fan is installed on one side of the rear baffle, a mounting seat is installed at the middle position of the transmitter body, a pair of slide grooves are symmetrically provided on both sides of the top of the mounting seat, a slider is slidably installed in the slide groove, a protective shell is installed on the side of the transmitter body away from the rear baffle, and one side of the bottom end of the protective shell is connected to a pair of sliders, a vent is provided on one side of the protective shell, inclined blocks are installed on the top of both sides of the protective shell, and a humidity sensor is installed on the top of the protective shell.

[0007] Furthermore, a screw rod is rotatably installed inside one of the pair of slide grooves, and the screw rod passes through the front and rear sides of the slider and is threadedly connected to the slider.

[0008] Furthermore, a motor is installed on one side of the rear baffle, and the output end of the motor is connected to the screw drive through a coupling.

[0009] Furthermore, the temperature sensor and the humidity sensor are both electrically connected to the motor.

[0010] Furthermore, the length of the protective shell is greater than the length of the mounting seat.

[0011] Furthermore, an observation window is installed on one side of the protective shell.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The explosion-proof temperature transmitter with heat dissipation function in the utility model is convenient for heat dissipation of the temperature transmitter through the coordinated use of the rear baffle, the temperature sensor, the heat dissipation fan, the mounting seat, the slide groove, the slider, the protective shell, the vent, the inclined block, the humidity sensor, the screw and the motor. In addition, when there is a lot of moisture in the environment or in rainy weather, the temperature transmitter body is shielded and protected by the protective shell to reduce the entry of moisture into the temperature transmitter body to cause a short circuit in the circuit, thereby extending the service life of the temperature transmitter.

[0014] The explosion-proof temperature transmitter with heat dissipation function in the utility model cooperates with the rear baffle, the temperature sensor, the mounting seat, the slide groove, the slider, the protective shell, the screw and the motor. When the temperature sensor detects that the temperature is too high, the protective shell is used to block and isolate the temperature transmitter, so as to avoid greater losses caused by spontaneous combustion and explosion of the temperature transmitter.

[0024] Example:

[0025] As attached Figure 1 To Attachment Figure 4 As shown:

[0026] The utility model provides an explosion-proof temperature transmitter with a heat dissipation function, comprising a transmitter body 1, a rear baffle 2 is installed on one side of the transmitter body 1, a temperature sensor 3 is installed on one side of the rear baffle 2 at a position close to the transmitter body 1, a heat dissipation fan 4 is installed on one side of the rear baffle 2, a mounting seat 5 is installed at the middle position of the transmitter body 1, a pair of slide grooves 6 are symmetrically arranged on both sides of the top of the mounting seat 5, a slider 7 is slidably installed in the slide groove 6, a protective shell 8 is installed on the side of the transmitter body 1 away from the rear baffle 2, and one side of the bottom end of the protective shell 8 is connected to the pair of sliders 7, a vent 9 is provided on one side of the protective shell 8, inclined blocks 10 are installed on the tops of both sides of the protective shell 8, and a humidity sensor 11 is installed on the top of the protective shell 8.

[0027] Among them, a screw rod 12 is rotatably installed inside one of the pair of slide grooves 6, and the screw rod 12 passes through the front and rear sides of the slider 7 and is threadedly connected to the slider 7. Through the rotation of the screw rod 12, under the limiting action of the slide groove 6, the slider 7 moves back and forth, thereby driving the protective shell 8 to move back and forth, thereby realizing shielding and protection of the transmitter body 1.

[0028] A motor 13 is installed on one side of the rear baffle 2, and the output end of the motor 13 is transmission-connected to the screw 12 via a coupling. The motor 13 drives the screw 12 to rotate, thereby driving the slider 7 to move.

[0029] The temperature sensor 3 and the humidity sensor 11 are both electrically connected to the motor 13 , and the temperature and humidity are detected by the temperature sensor 3 and the humidity sensor 11 , thereby controlling the motor 13 to be turned on or off.

[0030] The length of the protective shell 8 is greater than the length of the mounting base 5 , so as to completely cover the transmitter body 1 .

[0031] An observation window 14 is installed on one side of the protective shell 8 to facilitate observation when the transmitter body 1 is blocked.

[0032] The working principle of this embodiment: after the staff installs the transmitter body 1 to the designated position, they turn on the cooling fan 4 to dissipate the heat of the transmitter body 1. When the humidity sensor 11 detects that the external humidity is high or it is rainy, the motor 13 is turned on, and the motor 13 drives the screw 12 to rotate. Through the rotation of the screw 12, under the limiting action of the slide groove 6, the slider 7 moves back and forth, and then drives the protective shell 8 to move back and forth, so as to achieve shielding and protection of the transmitter body 1, and prevent a large amount of moisture from entering the transmitter body 1 and causing a short circuit to cause spontaneous combustion. Similarly, when the temperature sensor 3 detects that the temperature of the transmitter body 1 is too high, the motor 13 is turned on, so that the protective shell 8 completely shields the transmitter body 1, and prevents the transmitter body 1 from spontaneously igniting or exploding due to excessive temperature, and the fire spreads to the surrounding environment to cause greater losses.
