Description

Technical Field

[0001] The present invention belongs to the technical field of temperature monitoring, and in particular relates to a non-contact temperature monitoring device and method under high temperature environment. Background Art

[0002] In industrial production, scientific research and many practical application scenarios, temperature monitoring in high temperature environments has always been a critical and challenging topic. Traditional contact temperature monitoring methods, such as the use of thermocouples and thermal resistors, face many difficult-to-overcome problems in high temperature environments. On the one hand, contact sensors need to be in direct contact with the object being measured. At high temperatures, the material of the sensor itself may undergo physical or chemical changes, such as thermal expansion, corrosion, and melting of the material. This will not only affect the measurement accuracy of the sensor, but also greatly shorten its service life. Frequent replacement of sensors will lead to high maintenance costs and the risk of production interruption.

[0003] With the development of science and technology, non-contact temperature monitoring technology has emerged, among which the temperature monitoring method based on the principle of infrared radiation is the most widely used. However, the existing non-contact temperature monitoring devices still have many shortcomings in high temperature environments. High temperature environments also place extremely high demands on the hardware performance of the monitoring device. The optical elements, detectors, and electronic circuits in the existing non-contact temperature monitoring devices are prone to performance drift, increased noise, and other problems under long-term high temperature, further reducing the reliability of the monitoring device. Therefore, the heat dissipation performance directly affects the accuracy of the data. Most of the existing non-contact temperature monitoring devices use air cooling, which has poor heat dissipation effect. At the same time, the existing non-contact temperature monitoring devices are fixed when in use, which makes it impossible to adjust the monitoring angle according to different situations and realize temperature monitoring of different positions.

[0018] When S2 is in use, if it is necessary to measure the temperature at different locations, the non-contact temperature sensor can be adjusted in time by controlling the rotation angle of the fixed frame and the rotation angle of the non-contact temperature sensor in the fixed frame, so as to measure the temperature at different locations in time.

[0042] Example 1, please refer to Figure 1 and Figure 8A non-contact temperature monitoring device in a high temperature environment comprises a non-contact temperature sensor 3, a base plate 5 and a display instrument 1, wherein a transmission line 2 connected to the non-contact temperature sensor 3 and the display instrument 1 is provided for signal transmission, a rotatable and U-shaped fixing frame 4 is provided on the base plate 5, and the non-contact temperature sensor 3 can be installed on the fixing frame 4 so as to rotate up and down, and a liquid cooling pipe for cooling is provided in the non-contact temperature sensor 3, and the liquid cooling pipe is wrapped around the heat dissipation area. On the outside of the part, the display instrument 1 is provided with a liquid cooling box 11, in which coolant is stored, and a delivery pump 111 for delivering the coolant is provided in the liquid cooling box 11, and a liquid inlet pipe 114 and a return pipe 115 are provided in the transmission line 2, one end of the liquid inlet pipe 114 is connected to the liquid inlet end of the liquid cooling pipe, and the other end of the liquid inlet pipe 114 is connected to the output end of the delivery pump 111, one end of the return pipe 115 is connected to the liquid cooling box 11, and the other end of the return pipe 115 is connected to the liquid outlet end of the liquid cooling pipe. The shell of the non-contact temperature monitor 3 is made of constant temperature insulation material.

[0043] The design of the base plate 5 and the fixed frame 4 can realize the adjustment of the monitoring angle of the non-contact temperature sensor 3, so that timely temperature monitoring of different positions can be performed according to needs. The design of the liquid cooling tube can timely cool the parts inside the non-contact temperature sensor 3 through liquid cooling, thereby ensuring the stability and accuracy of temperature monitoring.

[0044] In this example, see Figure 1 , Figure 2 and Figure 3The bottom of the base plate 5 is provided with a fixing hole for fixing with bolts at a set position, and the middle of the base plate 5 is provided with a first adjusting groove 56, the first adjusting groove 56 is provided with a first adjusting gear 41, the first adjusting gear 41 is fixedly connected to the bottom of the fixing frame 4, one end of the first adjusting groove 56 is provided with a second adjusting groove 57 connected to each other, the adjusting groove is provided with a second adjusting gear 54 that is rotatable and meshes with the first adjusting gear 41, the second adjusting groove 57 is provided with a first rack 52 that is slidably connected and meshes with the second adjusting gear 54, and the second adjusting groove 5 7 is provided with a fixedly connected first hydraulic rod 51, the extended end of the first hydraulic rod 51 is connected to the first rack 52, the second regulating groove 57 is also provided with a first spring 53 for driving the first rack 52 to automatically restore the initial position, the second regulating groove 57 is provided with a fixedly connected connecting shaft 58, the second regulating gear 54 is unidirectionally rotatably connected to the connecting shaft 58, the liquid cooling pipe is provided with a connected shunt pipe 55, the extended end of the shunt pipe 55 is connected to the liquid inlet end of the first hydraulic rod 51, and the return pipe 115 is provided with an openable and closable control valve 116. Among them, the fixed base is provided with a through-type guide hole 42, the guide hole 42 passes through the middle of the first regulating gear 41, and the shunt pipe 55 passes through the guide hole 42.

[0045] The design of the shunt pipe 55, the first spring 53 and the control valve 116 can increase the hydraulic pressure in the liquid cooling pipe by closing the control valve 116 when the rotation angle of the fixed frame 4 needs to be controlled, so that the hydraulic pressure can push the first hydraulic rod 51 to extend, so that the first hydraulic rod 51 can overcome the elasticity of the first spring 53 and drive the first rack 52 to move, and the first rack 52 is meshed with the second adjusting gear 54. Through the meshing transmission of the gears, the rotation of the first adjusting gear 41 is realized, and the first adjusting gear 41 is fixedly connected to the fixed frame 4, thereby realizing the rotation control of the fixed frame 4. When the control valve 116 is opened, the elasticity of the first spring 53 can drive the first rack 52 to restore the initial position. Due to the one-way rotation connection between the second adjusting gear 54 and the connecting shaft 58, the first rack 52 will not drive the second adjusting gear 54 to move during the backward movement, that is, the fixed frame 4 will not rotate as a result.

[0046] Such a design enables the coolant to cool down the internal parts of the non-contact temperature sensor 3 while also controlling the angular rotation of the fixing frame 4 through hydraulic transmission.

[0047] In this example, see Figure 4A symmetrically distributed rotating shaft 31 is provided on both side walls of one end of the fixed frame 4, and the rotating shaft 31 is rotatably connected to the two side walls of the non-contact temperature sensor 3. A rotatably connected second hydraulic rod 44 is provided at the bottom of the other end of the fixed frame 4, and a sliding plate is provided at the bottom of the non-contact temperature sensor 3. The extending end of the second hydraulic rod 44 is rotatably connected to the sliding plate.

[0048] The second hydraulic rod 44 cooperates with the rotating shaft 31 , and the rotation angle of the non-contact temperature sensor 3 can be controlled by utilizing the extension and retraction of the second hydraulic rod 44 .

[0049] In this example, see Figure 4 , Figure 6 and Figure 7 A fixedly connected driving box 43 is provided on the fixed frame 4, a fixedly connected adjusting box 433 is provided inside the driving box 43, a piston plate 436 which can move back and forth is provided inside the adjusting box 433, and a connecting guide pipe 45 is provided at an outlet on one side of the adjusting box 433, and the guide pipe 45 is connected to the liquid inlet end of the second hydraulic rod 44.

[0050] In this example, see Figure 4 , Figure 5 and Figure 6 and Figure 7 The middle of the regulating box 433 is provided with a rotatable regulating shaft 434, the regulating shaft 434 movably passes through the middle of the piston plate 436, and the regulating shaft 434 is provided with a reciprocating thread 435 connected to the piston plate 436, and the outer side of the regulating shaft 434 is provided with a spring hose for sealing, one end of the spring hose is rotatably connected to the inner wall of the regulating box 433, and the other end of the spring hose is rotatably and sealedly connected to the piston plate 436, the liquid cooling pipe includes a first pipe 61, a second pipe 62, a third pipe 63 and a fourth pipe 64, the first pipe 61, the second pipe 62, the third pipe 63 and the fourth pipe 64, The third tube 63 is connected to the fourth tube 64, and a fixedly connected regulating tube 431 is provided in the driving box 43, the second tube 62 is connected to the liquid inlet end of the regulating tube 431, and the third tube 63 is connected to the liquid outlet end of the other end of the regulating tube 431, and a third regulating gear 437 connected to unidirectional rotation is provided on the outer side of the regulating shaft 434, and a second rack 432 meshing with the third regulating gear 437 is provided on the regulating tube 431, and a sealing plate 4311 that can move back and forth and is used to drive the second rack 432 to move back and forth synchronously is provided in the regulating tube 431. The spring hose is used to ensure the sealing of the hydraulic pressure when the piston plate 436 reciprocates.

[0051] In this example, see Figure 7 and Fig. 9A through-type third regulating groove 4314 is provided on one side wall in the middle of the regulating tube 431, and interconnected positioning grooves 4313 are provided on both side walls of the third regulating groove 4314. A sliding and sealed regulating plate 4315 is provided in the positioning groove 4313, and the sealing plate 4311 is slidably and sealedly connected to the regulating tube 431. A one-way valve 4312 for one-way passage of liquid is provided on the sealing plate 4311, and a second spring 4316 for automatically restoring the regulating plate 4315 to its initial position is provided in the positioning groove 4313.

[0052] The design of the first tube 61, the second tube 62, the third tube 63 and the fourth tube 64 can change the flow direction of the coolant that originally only passes through the non-contact temperature sensor 3 through the diversion of the second tube 62 and the third tube 63, so that the coolant can pass through the regulating tube 431. The design of the sealing plate 4311 and the one-way valve 4312 allows the coolant to pass through the one-way valve 4312 normally when the coolant passes in the normal downstream direction. When it is necessary to control the extension and retraction of the second hydraulic rod 44, it is only necessary to control the reverse flow of the coolant. At this time, the coolant cannot pass through the one-way valve 4312, and the hydraulic pressure can only push the sealing plate 4311 to move. The movement of the sealing plate 4311 can bring The movable adjustment plate 4315 moves synchronously, so that the second rack 432 drives the third adjustment gear 437 to rotate. Due to the characteristics of the reciprocating thread 435, the reciprocating motion of the piston plate 436 is realized. The reciprocating motion of the piston plate 436 can be synchronized by hydraulic pressure, so that the second hydraulic rod 44 can perform telescopic motion, thereby adjusting the rotation angle of the non-contact temperature sensor 3. Since the third adjustment gear 437 is unidirectionally connected to the adjustment shaft 434, when the rotation angle is adjusted, the coolant flows downstream, and the sealing plate 4311 returns to its initial position. The movement of the second rack 432 will not drive the adjustment shaft 434 to rotate, thereby ensuring the stability of the angle after adjustment.

[0053] In this example, see Figure 8 The liquid cooling box 11 has two first holes on its side wall, which are connected to the liquid inlet pipe 114 and the return pipe 115 respectively. The inner wall of the liquid cooling pipe is provided with a rotating and sealed regulating disk 113. The regulating disk 113 is provided with a second hole 117 corresponding to the first hole. A connecting pipe 112 is provided between the liquid outlet of the delivery pump 111 and one of the second holes 117. By rotating the regulating disk 113, the control of the downstream and upstream directions of the coolant in the liquid cooling pipe is realized. The second pipe 62, the third pipe 63 and the connecting pipe 112 are all flexible hoses.

[0054] When using this application:

[0055] (1) First, the base plate 5 is fixedly installed at the position where the temperature needs to be measured, and then the fixing frame 4 is installed on the base plate 5, and then the non-contact temperature sensor 3 is installed on the fixing frame 4, and finally the transmission line 2 is connected to the display instrument 1;

[0056] (2) When it is necessary to adjust the monitoring angle of the non-contact temperature sensor 3, the control valve 116 is first closed, while the delivery pump 111 delivers normally. At this time, the hydraulic pressure in the liquid cooling pipe increases, so that the hydraulic pressure of the liquid cooling pipe can push the first hydraulic rod 51 to extend through the shunt pipe 55, so that the first hydraulic rod 51 can overcome the elasticity of the first spring 53 and drive the first rack 52 to move. The first rack 52 is meshed with the second adjusting gear 54. Through the meshing transmission of the gears, the rotation of the first adjusting gear 41 is realized. The first adjusting gear 41 is fixedly connected to the fixed frame 4, thereby realizing the rotation control of the fixed frame 4. When the control valve 116 is opened, the elasticity of the first spring 53 can drive the first rack 52 to restore the initial position. Due to the one-way rotation connection between the second adjusting gear 54 and the adjusting shaft 434, the first rack 52 will not drive the second adjusting gear 54 to move during the backward movement, that is, the fixed frame 4 will not rotate as a result. The fixed frame 4 can be rotated to the set angle by the coordinated method of closing and opening the control valve 116 multiple times;

[0057] (3) Then, the control valve 116 is opened, and then the control adjustment disk 113 is rotated to connect the delivery pump 111 with the return pipe 115. At this time, with the continuous delivery of the delivery pump 111, the coolant in the liquid cooling pipe changes from downstream to reverse flow. Due to the one-way valve 4312 on the sealing plate 4311, the coolant cannot flow back through the one-way valve 4312. At this time, the hydraulic pressure of the coolant increases, which can push the sealing plate 4311 to move, thereby causing the second rack 432 to move, and through the gear meshing method, driving the adjustment shaft 434 to rotate, and then with the characteristics of the reciprocating thread 435, driving the reciprocating motion of the piston plate 436, thereby realizing the telescopic control of the second hydraulic rod 44, so that the non-contact temperature sensor 3 can rotate to the set angle;

[0058] (4) By coordinating the rotation angle control of the fixed frame 4 with the rotation angle control of the non-contact temperature sensor 3, the non-contact temperature sensor 3 can be adjusted to a set angle and adjusted in time to monitor the required position.

[0059] Such a design can enable the coolant to cool the non-contact temperature sensor 3 while also enabling the rotation angle of the non-contact temperature sensor 3 to be controlled by coordinating the flow direction of the coolant through the shunt tube 55 and the regulating tube 431 .
