Existing thermocouple sensors are screwed into the burner pipe, which makes it inconvenient to change their position, resulting in inaccurate detection of burner temperature or damage due to excessive temperature.
A clamping mechanism is used to fix the fixed chamber to the burner pipeline. The position of the thermocouple sensor can be flexibly changed through the clamping parts and the installation mechanism. The pipeline temperature is transferred to the sensor through the heat-concentrating cylinder and heat-conducting plate. The height is adjusted by the adjustment mechanism to avoid damage.
This allows for flexible adjustment of the thermocouple sensor position, avoiding damage caused by it being too close or too far away, and improving the accuracy and reliability of temperature detection.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of boiler equipment technology, and in particular to a fixing mechanism for detecting the temperature of a boiler burner. Background Technology
[0002] A boiler is an energy conversion device. The energy input to a boiler includes the chemical energy of fuel and electrical energy. The boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of thermal energy. The burner is the key component of the boiler equipment for combustion.
[0003] When the burner is working, it usually needs to use a temperature sensor to detect the temperature. With temperature monitoring, the operating status of the burner can be understood at any time by observing temperature changes, and the amount of fuel added around the boiler can be adjusted to enhance combustion in low-temperature areas and improve combustion efficiency.
[0004] Existing thermocouple sensors are installed in the burner pipe by screwing them in, thereby measuring the temperature of the burner pipe. This makes it inconvenient to change the position of the thermocouple sensors. When the actual required burner temperature is too low, the thermocouple sensor installed at a distance cannot detect the burner temperature. Conversely, excessively high temperatures can damage the thermocouple sensor installed at a closer distance. Utility Model Content

Detailed Implementation
[0022] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.
[0023] See appendix Figure 1-4 As shown, the fixing mechanism for boiler burner temperature detection in Embodiment 1 includes a fixing chamber 1, which has a clamping mechanism inside; a mounting box 2 on the fixing chamber 1, which has a mounting mechanism inside; and a thermocouple sensor 3 detachably connected to the mounting mechanism.
[0024] The clamping mechanism can fix the fixed chamber 1 to the combustion pipeline. If the burner maintains a stable temperature, the installation position can be 1.5 meters away from the burner. If the burner temperature needs to be changed according to the combustion technology, the installation position can be changed through the clamping mechanism to avoid damage to the thermocouple sensor 3 due to being too close, and also to prevent the thermocouple sensor 3 from being too far away to detect the working temperature of the burner. The clamping method allows the position of the thermocouple sensor 3 to be flexibly changed, improving its practicality. The installation mechanism can install the thermocouple sensor 3 in the installation box 2 and can transfer the temperature of the pipeline to the thermocouple sensor 3, thereby inferring the working temperature of the burner from the temperature of the pipeline, further reducing the damage caused by the high-temperature stack thermocouple sensor 3.
[0025] The clamping mechanism includes: a bidirectional lead screw 11 rotatably disposed inside the fixed chamber 1; nut seats 12 sleeved on both ends of the bidirectional lead screw 11; and a clamping member 13 fixed to the nut seats 12 and extending to the bottom of the fixed chamber 1.
[0026] When the bidirectional lead screw 11 is working, it can drive the nut seat 12 to move in both directions. When the nut seat 12 drives the clamping member 13 to move closer to each other, the clamping member 13 clamps the combustion pipe, thereby achieving fixation.
[0027] The mounting mechanism includes: a heat-concentrating cylinder 21 located inside the mounting box 2 and capable of transferring heat to the thermocouple sensor 3, the heat-concentrating cylinder 21 allowing the thermocouple sensor 3 to be inserted; an adjustment mechanism located inside the mounting box 2 capable of adjusting the height of the heat-concentrating cylinder 21; and a heat-conducting plate 25 located at the bottom of the heat-concentrating cylinder 21 for contact with the combustion pipe.
[0028] The heat-conducting plate 25 can transfer the temperature of the combustion pipe to the heat-collecting cylinder 21. Since the thermocouple sensor 3 is inserted into the heat-collecting cylinder 21, the temperature of the combustion pipe can be detected by the thermocouple. The height of the heat-collecting cylinder 21 can be adjusted by the adjustment mechanism. When it is not necessary to detect the temperature, the height of the heat-conducting plate 25 can be raised to move away from the combustion pipe. When the adjustment mechanism moves the heat-conducting plate 25 down, it can not only be in close contact with the combustion pipe, but also work with the clamping part 13 to increase the firmness after fixing.
[0029] Furthermore, the side of the clamping member 13 facing the combustion pipe is a transition arc surface 14.
[0030] Since the pipe is cylindrical, the transition arc surface 14 can increase the friction between the clamping part 13 and the outside of the pipe, thereby increasing the stability after clamping.
[0031] Furthermore, the mounting box 2 is equipped with rotatable rollers 4 on both sides.
[0032] When the clamping parts 13 are far apart, they can be slightly loosened and supported by the rollers 4, which facilitates the displacement of the device on the pipe wall.
[0033] Furthermore, the clamping member 13 is provided with an adaptive friction mechanism on the side facing the combustion tube. The friction mechanism includes: a plurality of columns 15 fixed on the clamping member 13; and a friction block 16 disposed at the other end of the columns 15 and rotatably connected thereto.
[0034] Because the diameters of the combustion pipes are different, when the clamping parts 13 approach each other on the outer wall of the pipe, the friction block 16 will rotate and completely adhere to the outer wall of the pipe, thereby avoiding point contact between the clamping parts 13 and the pipe.
[0035] Furthermore, the fixed chamber 1 is provided with a slide rod 18 inside, and a slide sleeve 19 that is fixedly connected to the nut seat 12 is slidably connected to the slide rod 18.
[0036] The sliding sleeve 19 can limit the nut seat 12 and increase its stability during movement.
[0037] Furthermore, one end of the bidirectional lead screw is fixed with a knob 17 extending outside the fixed chamber 1.
[0038] The bidirectional lead screw can be rotated by knob 17, thereby enabling manual clamping and facilitating disassembly and replacement.
[0039] Furthermore, the heat-concentrating cylinder 21 is provided with a threaded sleeve 22, and the thermocouple sensor 3 is provided with a threaded post 31 that engages with the threaded sleeve 22.
[0040] The threaded sleeve 22 can be screwed into the threaded post 31 to fix the thermocouple sensor 3.
[0041] Furthermore, the adjustment mechanism includes: an electric telescopic rod 23 located inside the mounting box 2; and a connector 24 located at the output end of the electric telescopic rod 23 and fixedly connected to the heat-concentrating cylinder 21.
[0042] When in operation, the electric telescopic rod 23 can drive the heat-collecting cylinder 21 to adjust its vertical height through the connector 24, so that the heat-conducting plate 25 can be attached to the pipe wall.
[0043] like Figure 5 The formula shown can be used to calculate the internal temperature of a pipe from the temperature of its outer wall, employing Fourier's law. Where: dT / dx is the rate of temperature change along the radial direction of the pipe; dQ / dx is the heat flux density; c is the specific heat capacity of the material (J / (kg·K)); ρ is the density of the material (kg / m³). 3 ).
[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
