Description

Technical Field

[0001] The invention relates to the field of temperature detection and control, and to a temperature estimation device in an extremely high temperature environment. Background Art

[0002] High temperature working environment is an indispensable working environment in our current life, especially for special operations, high temperature environment is commonplace. With the common development of science and technology and the times, more and more methods of resisting high temperature have gradually emerged, including rapid cooling and maintaining constant temperature. Various methods are being used for related cooling and temperature control operations, but when controlling the cooling, it is often easy to ignore the problem of temperature threshold, that is, cooling does not occur in the whole process, but is an operation that will be carried out when the temperature reaches the threshold range or the warning range. In order to reduce the workload, the existing technology often does not consider this problem and adopts full-process cooling, especially in some extreme high temperature environments with temperatures above 100°C and below 280°C. The full-process cooling method is not optimistic and often does not achieve the expected effect.

[0003] In the prior art, in order to solve the above problems, temperature monitoring is generally used. However, temperature monitoring places high demands on the devices for temperature monitoring, especially in extremely high temperature environments. However, according to the data on temperature measuring equipment scrapped each year in special operations, it can be seen that the annual equipment scrapping rate is as high as 35%, which directly shows that the existing temperature measuring devices are not effective and the temperature measurement principles and methods do not use extreme high temperatures. Summary of the invention

[0004] The purpose of the present invention is to provide a temperature estimation device in an extremely high temperature environment, so as to solve the problem that the prior art cannot perform reasonable temperature threshold detection and thus perform reasonable temperature control in extremely high temperatures.

[0005] The object of the present invention is achieved by the following technical solution, comprising a device body, one end of which is movably connected to a temperature measuring component, and the other end of which is detachably connected to an air inlet pipe for guiding the wind direction, and a control component and a heat conduction component connected to the control component are also arranged in the device body;

[0006] The control component is electrically connected to an adjuster for cooperating with temperature detection feedback. The heat conduction component includes a graded heat conduction cavity, and the graded heat conduction cavity includes a plurality of heat conduction channels arranged side by side for passing different temperatures. A constant temperature heat source of different temperature is arranged in each heat conduction channel.

[0007] It should be noted that, as a practitioner in the special operations industry, the applicant has always been troubled by the high temperature environment in the special operations environment, because the current existing technology does not have a device that can reasonably detect the temperature threshold and perform reasonable temperature control. The applicant has tried biological temperature detectors, volcanic environment temperature detectors and temperature detectors under some extremely cold conditions, and combined them with intelligent equipment to perform temperature measurement, temperature control and other operations. In the end, it was found that the above-mentioned thermometers would fail and other phenomena and could not operate normally and continuously. Based on this, the applicant thought that if the temperature of the gas itself could be used for measurement, and the chemical, physical and other properties of the object itself could be used, it should be more stable than external intervention and the service life would be longer. Based on this idea, the applicant combined relevant operations in the fields of biology, chemistry, etc., and designed the device described in this application. The core idea is to use the properties of the gas itself for measurement and control, and add adjusters, constant temperature heat sources, etc.

[0008] The graded heat-conducting cavity is connected to the collecting cavity, and a heater is arranged in the collecting cavity. The heating range of the heater is 5° C.-10° C., wherein the collecting cavity is configured to reheat the hot air from the graded heat-conducting cavity.

[0009] It should be noted that the collection chamber is provided to increase the temperature and change the flow rate, and its main purpose is to heat the gas so as to output the gas whose temperature can be compared.

[0010] The heat-conducting collecting cavity is connected with a conduction tube, and the front end diameter of the conduction tube is smaller than the rear end diameter.

[0011] It should be noted that the provision of a conduction tube and the change in diameter can efficiently regulate the gas flow rate and ensure the gas transmission speed, thereby assisting in increasing the thermal energy between gas molecules.

[0012] The end of the transmission tube is connected to a delivery cavity, and a plurality of delivery tubes are arranged at intervals inside the delivery cavity, wherein the delivery tubes are configured to transmit pressurization.

[0013] It should be noted that the provision of a delivery pipe is also based on the consideration of increasing the gas flow rate again, which is equivalent to assisting the activation of thermal energy again. However, since the gas here has been accelerated once, accelerating it again here can ensure that the thermal energy of the gas reaches a more efficient state. The prior art uses the thermal energy of the gas itself, which is common in biological culture. The applicant converts it into the measurement of ambient temperature and uses it for conversion, which can effectively ensure the stability of the thermal energy of the gas.

[0014] The delivery chamber is externally connected with a guide pipe, and the guide pipe is used to collect the gas from the delivery chamber and perform pressurization processing.

[0015] It should be noted that the guide pipe will perform gas compression operations and can be adjusted according to the attached Figure 2 It is clear that the purpose of the applicant setting up the guide pipe is to uniformly compress the gas and increase the flow rate.

[0016] The heat conduction component is connected to a transition duct outside, a flow groove is provided on the outer periphery of the transition duct, and a flow pipe for auxiliary exhaust is connected to the flow groove.

[0017] It should be noted that the provision of the flow groove can provide a pressure relief effect inside the device, ensuring that the temperature and pressure in the transition duct are within an appropriate range.

[0018] The lower end of the transition duct is connected with a thermal insulation pipe, and the inner wall of the thermal insulation pipe is coated with a thermal insulation material.

[0019] It should be noted that the purpose of providing the insulation pipe is to minimize external interference with the gas during its flow, and to reduce the impact of changes in external temperature on the temperature of the gas in the pipe.

[0020] The temperature measuring component includes a constant pressure chamber connected to the insulation tube, the constant pressure chamber is connected to a liquid flow tube, an elastic push block for receiving temperature feedback is elastically arranged under the liquid flow tube, and a pressure sensor is arranged on the surface of the elastic push block

[0021] It should be noted that the constant pressure chamber is mainly used to balance the pressure. When the constant pressure chamber is unbalanced, it means that the temperature has changed or the temperature has exceeded the threshold.

[0022] A temperature measuring head for sensing ambient temperature is movably connected below the elastic push block. The temperature measuring head is arranged below the liquid flow tube. A driving module for driving operation is arranged inside the temperature measuring head. The driving module is connected to the pressure sensor signal.

[0023] It should be noted that the drive module provided in the temperature measuring head can effectively receive the driving pressure brought by the external gas pressure, lift the elastic push block to the corresponding height, and maintain the pressure value in the pipe.

[0024] The regulator is electrically connected to a rechecker for frequency modulation inspection.

[0025] It should be noted that the rechecker is set to ensure the correctness of the frequency modulation result.

[0026] Compared with the prior art, the present invention has the following advantages and beneficial effects: a plurality of heat conduction channels for different temperatures are arranged side by side in a graded heat conduction cavity, and a constant temperature heat source with different temperature is arranged in each heat conduction channel. Such an arrangement can ensure that the external input temperature is effectively and reasonably increased, so that the temperature is measured and controlled intuitively by heating. At the same time, the control component is arranged to ensure that the temperature can be adjusted in time after entering the heat conduction channel. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] Please refer to the attached instructions Figure 1 - Instructions attached Figure 2 This embodiment provides a temperature estimation device in an extremely high temperature environment. The estimation device is mainly used to solve the problem that the prior art cannot perform reasonable temperature threshold detection and then perform reasonable temperature control in extremely high temperatures. The estimation device is already in the actual use stage.

[0031] The specific implementation method of the present application is as follows: the estimation device includes a device body, one end of the device body is movably connected to a temperature measuring component, and the other end is detachably connected to an air inlet duct for guiding the wind direction. Here, the applicant needs to emphasize that the temperature control component of the present application is used in an extremely high temperature environment. Therefore, in this type of environment, efficient instrument detection cannot be carried out, nor can it be performed solely by manual labor. Therefore, the present application was developed and designed under this state, and the main line of the design concept is also the same.

[0032] The device body is also provided with a control component and a heat-conducting component connected to the control component; the control component is electrically connected with an adjuster for cooperating with temperature detection feedback, wherein the adjuster can be connected to the outside world, and the result that needs frequency modulation is transmitted, and then the operation control is performed to obtain the frequency modulation result. Because the device of the present application is partially in a high-temperature environment and partially in a normal environment, manual frequency modulation coordination operation is required. The heat-conducting component includes a graded heat-conducting cavity, and the graded heat-conducting cavity includes a plurality of heat-conducting channels arranged side by side for different temperatures to pass through. The applicant does not limit the different temperatures, and any temperature can be input. Constant-temperature heat sources of different temperatures are arranged in each heat-conducting channel, and there is a difference between the temperatures of the constant-temperature heat sources, and the difference is 10°C, that is, the temperature of the constant-temperature heat sources in each adjacent heat-conducting channel differs by 10°C, and the constant-temperature heat sources need to be continuously heated. The graded heat conduction cavity is connected to the collecting cavity, and a heater is arranged in the collecting cavity. The heating range of the heater is 5°C-10°C. The purpose of continuing heating here is to shorten the time of temperature measurement. Another preferred implementation of this embodiment is to use a heat conduction cavity instead.

[0033] The collecting chamber is used to reheat the hot gas from the graded heat transfer chamber. The collecting heat transfer chamber is connected to a conduction tube. The front end diameter of the conduction tube is smaller than the rear end diameter. The arrangement of conduction tubes of unequal diameters can ensure that the gas is pressurized in a special shape due to different shapes, thereby changing the pressure, increasing the flow rate, and thus increasing the pressure.

[0034] The end of the conduction tube is connected to a delivery cavity, and a plurality of delivery tubes are arranged at intervals inside the delivery cavity, wherein the delivery tube is arranged for conduction and pressurization, and a guide tube is connected to the outside of the delivery cavity, and the guide tube is used to collect gas from the delivery cavity and perform pressurization treatment, and a transition duct is connected to the outside of the heat conduction component, and a flow groove is provided on the outer periphery of the transition duct, and a flow tube for auxiliary exhaust is connected to the flow groove. The provision of the flow groove can ensure that the gas in the device body is discharged faster, and the principle of discharge is that the gas flows from high temperature to low temperature, and from high pressure to low pressure.

[0035] The lower end of the transition duct is connected to an insulation pipe, and the inner wall of the insulation pipe is covered with insulation material. The temperature measuring component includes a constant pressure chamber connected to the insulation pipe, and the constant pressure chamber is connected to a liquid flow pipe. An elastic push block for receiving temperature feedback is elastically arranged under the liquid flow pipe, and a pressure sensor is arranged on the surface of the elastic push block. A temperature measuring head for sensing ambient temperature is movably connected below the elastic push block. The temperature measuring head is arranged below the liquid flow pipe, and a driving module for driving the operation is arranged in the temperature measuring head. The driving module is connected to the pressure sensor signal, and the regulator is electrically connected to a repeater for frequency modulation inspection.

[0036] In combination with the above technical solutions and related technical features, the operation process of this application is further described here:

[0037] First, the operator sets the estimation device in the environment where the measurement is required. It should be noted that the setting process must ensure that one end of the air inlet is in a normal environment and the other end of the device is in an extreme high temperature condition, wherein the extreme high temperature condition is in the range of 100°C-280°C. Of course, other temperatures can also be tested. The applicant only uses this temperature as the experimental effect research object of this application. At the same time, the device of this application can also measure different media, such as steel and concrete interlayers, different fluid medium interlayers, etc. The interlayer can be understood as a hamburger shape. When the device is measured, it can be understood as penetrating from top to bottom, with one end at the top and the other end at the bottom.

[0038] After setting up the estimation device, blow hot wind at the air inlet. After the wind enters the device, it will quickly reach the graded heat conduction cavity along the air inlet pipe. In the cavity, because the wind itself has a certain amount of heat, the wind itself will match its heat with the heat of the heat conduction channel in the graded heat conduction cavity. When the heat of the wind itself is greater than the heat of the heat conduction channel, it will enter the corresponding heat conduction channel according to the heat pipe effect for heating. After heating, it will enter the collection cavity for heating again. After heating, it will enter the special-shaped conduction pipe to change the flow rate. When the flow rate changes, it will act on the potential energy between gas molecules at the same time, thereby obtaining a greater pressure. Then the gas will continue to conduct. At this time, if the temperature of the gas does not reach the minimum temperature set by the flow groove, the gas will enter the flow pipe and return to the graded heat conduction cavity again to repeat the operation until the gas can reach the preset value and continue to transmit. At this time, the control component will close the corresponding heat conduction channel, and the regulator is electrically connected to a re-test device for frequency modulation inspection for re-inspection.

[0039] After transmission, it will be conducted in the constant temperature tube. At this time, because the temperature measuring head has detected the ambient temperature, the size of the ambient temperature is transmitted to the driving module. The driving module will convert this temperature data into an initial startup value. It can be understood that the temperature here is a switch. When the temperature reaches the relevant set value, the driving module will drive the elastic push block to move. At this time, the gas transmitted from above will squeeze it. If the temperature and flow rate of the upper gas reach a value greater than the pressure of the elastic push block itself after the above process, the elastic push block will be pressed down. At this time, the pressure sensor set on the surface of the elastic push block will perform data transmission comparison. When the upper value is greater than the pressure on the push block, After that, the pressure sensor will return the value to the driving module, and then the driving module will wirelessly transmit the data to the outside world for reception. At this time, a temperature range value, that is, the threshold value, can be obtained. For example, after the operator adds gas with a temperature of 100°C from the air inlet pipe, after the above series of operations, the temperature becomes 150°C. At this time, the pressure above is assumed to press the elastic push rod down, which proves that the extreme temperature is less than 150°C. At this time, the operator can know the approximate threshold of the extreme temperature below, and then adjust the temperature of the gas to be input in the upper air inlet pipe. This process actively utilizes the performance of the gas itself, combined with the heat pipe effect, and can also greatly extend the service life of the device.

Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
