Description

Technical Field

[0001] The present invention belongs to the technical field of temperature measurement devices, and particularly relates to an in-engine pipeline temperature measurement device. Background Art

[0002] The in-engine pipeline temperature measurement device is an important tool for monitoring the temperature parameters of the engine and is crucial for ensuring the safe and efficient operation of the engine. It mainly consists of a temperature measurement mechanism and a fixing mechanism. During use, the temperature measurement mechanism is fixed to the pipeline through the fixing mechanism to measure the temperature at that position. If the temperature measurement mechanism is fixed on the inner wall of the pipeline, the temperature at the inner wall of the pipeline is measured, which is convenient for monitoring the temperature of the fluid inside the pipeline and is crucial for understanding the efficiency of the engine, the operating conditions of the lubrication system, and the effectiveness of the cooling system. If the temperature measurement mechanism is fixed on the outer wall of the pipeline, the temperature at the outer wall of the pipeline is measured, which is convenient for monitoring the temperature conditions of the pipeline itself and its external environment.

[0003] During the use of the existing in-engine pipeline temperature measurement device, generally only the temperature at a single position on the pipeline is measured, and the temperature difference cannot be obtained by measuring multiple positions simultaneously, which is not convenient for judging whether the engine is in a normal working state by means of the temperature difference. The efficiency of temperature measurement is insufficient. Moreover, when measuring the inner wall of the pipeline, the temperature measurement mechanism is usually fixedly connected to the pipeline, and it is difficult to adjust the temperature measurement position of the temperature measurement mechanism on the pipeline, resulting in insufficient convenience of temperature measurement. In addition, no impurity removal mechanism is usually provided on the outer wall of the pipeline, and impurities such as dust are easily attached to the outer wall of the pipeline, which hinders the fitting of the temperature measurement mechanism to the pipeline and affects the accuracy of the measurement result, resulting in insufficient reliability of temperature measurement. Summary of the Invention

[0004] The purpose of the present invention is to provide an in-engine pipeline temperature measurement device that can simultaneously measure the temperatures at two positions through two sliding cylinders provided on a connecting frame mechanism to obtain the temperature difference, so as to help judge whether the engine is in a normal working state and improve the efficiency of temperature measurement. The temperature measurement position of the temperature measurement probe on the pipe body can be adjusted by the inner wall measurement mechanism as the sliding cylinder slides, improving the convenience of temperature measurement. The impurity removal component can remove the impurities attached to the outer wall of the pipe by the outer wall measurement mechanism as the sliding cylinder slides, improving the reliability of temperature measurement.

[0043] To make the objectives and advantages of the present invention more clear and understandable, the present invention will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present invention, and does not strictly limit the scope of protection specifically claimed by the present invention.

[0044] Embodiment 1

[0045] As Figures 1-4 shown, this is the first embodiment of the present invention. This embodiment provides an in-engine pipeline temperature measurement device, which includes a body 10, on which a pipe body 11 is provided; a connecting frame mechanism 20, which is installed outside the pipe body 11 and is used to increase the number of temperature measurement positions. There are two sliding cylinders 21 on the connecting frame mechanism 20, and the sliding cylinders 21 are slidably installed with the pipe body 11; an inner wall measurement mechanism 30, which is arranged inside the sliding cylinders 21 and the pipe body 11 and is used to measure the temperature of the inner wall of the pipe body 11. There is a temperature measurement probe 31 on the inner wall measurement mechanism 30; an outer wall measurement mechanism 40, which is arranged between the sliding cylinders 21 and the pipe body 11 and is used to measure the temperature of the outer wall of the pipe body 11. There is a cleaning component 41 on the outer wall measurement mechanism 40.

[0046] When the present invention is in use, when it is necessary to measure the temperature of the pipe body 11, the inner wall measurement mechanism 30 and the outer wall measurement mechanism 40 at the sliding cylinders 21 respectively measure the temperature of the inner wall and the outer wall of the pipe body 11. Since there are two sliding cylinders 21, it is convenient to obtain the temperature difference between two positions to judge whether the engine is in a normal working state, improving the efficiency of temperature measurement. Among them, when the sliding cylinders 21 slide along the pipe body 11, they drive the inner wall measurement mechanism 30 to act, so that the temperature measurement probe 31 slides along the pipe body 11, facilitating the adjustment of the temperature measurement position of the temperature measurement probe 31 on the pipe body 11 and improving the convenience of temperature measurement. When the sliding cylinders 21 slide along the pipe body 11, they also drive the outer wall measurement mechanism 40 to act, so that the cleaning component 41 removes the impurities attached to the outer wall of the pipe body 11, reducing the situation where dust and other impurities attached to the outer wall of the pipe body 11 hinder the temperature measurement of the outer wall measurement mechanism 40 and improving the reliability of temperature measurement.

[0047] Embodiment 2

[0048] Referring to Figures 1-13 , this is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0049] As Figure 5 shown, the connecting frame mechanism 20 includes a fixed cylinder 22 fixedly connected to the pipe body 11. Telescopic components 23 are installed at both ends of the fixed cylinder 22, and the sliding cylinders 21 are installed at the ends of the telescopic components 23. There is a sliding component 24 between the sliding cylinders 21 and the pipe body 11.

[0050] According to the above structure, after the telescopic assembly 23 acts, it drives the sliding cylinder body 21 to slide along the pipe body 11, facilitating the sliding cylinder body 21 to drive the inner wall measuring mechanism 30 and the outer wall measuring mechanism 40 to act on the pipe body 11. After the telescopic assembly 23 acts, it drives the sliding cylinder body 21 to rotate, causing the relative position between the two sliding cylinder bodies 21 to change, facilitating the adaptation to the pipe body 11 at different angular positions.

[0051] As Figure 6 shown, the telescopic assembly 23 includes a first connecting plate 231 rotatably connected to the fixed cylinder body 22. The end of the first connecting plate 231 is slidably connected to a second connecting plate 232. The end of the second connecting plate 232 is rotatably connected to the sliding cylinder body 21. A first limiting hole 233 is provided inside the telescopic assembly 23, and a plurality of second limiting holes 234 are provided inside the second connecting plate 232. A limiting pin 235 is slidably connected inside the second limiting hole 234 and the first limiting hole 233.

[0052] It should be noted that the distribution direction of the second limiting holes 234 is the same as the sliding direction of the second connecting plate 232.

[0053] According to the above structure, when it is necessary to adjust the relative position between the two sliding cylinder bodies 21, after the first connecting plate 231 rotates along the fixed cylinder body 22, the first connecting plate 231 drives the sliding cylinder body 21 to rotate along the fixed cylinder body 22 through the second connecting plate 232, adjusting the angle between the sliding cylinder body 21 and the connecting frame mechanism 20, thereby adjusting the angle between the two sliding cylinder bodies 21. After the second connecting plate 232 slides along the first connecting plate 231, the second connecting plate 232 drives the sliding cylinder body 21 to slide along the first connecting plate 231, adjusting the distance between the sliding cylinder body 21 and the connecting frame mechanism 20, thereby adjusting the distance between the two sliding cylinder bodies 21, and further realizing the adjustment of the relative position between the two sliding cylinder bodies 21.

[0054] Among them, when it is necessary to slide the second connecting plate 232 along the first connecting plate 231, the limiting pin 235 is pulled out from the inside of the first limiting hole 233 and the second limiting hole 234, so that the limiting of the second connecting plate 232 and the first connecting plate 231 by the limiting pin 235 is released. The second connecting plate 232 is slid along the first connecting plate 231, so that the first limiting hole 233 corresponds to the second limiting hole 234 at a suitable position. The limiting pin 235 is inserted into the inside of the first limiting hole 233 and the second limiting hole 234, so that the limiting pin 235 limits the second connecting plate 232 and the first connecting plate 231, so that the relative position between the second connecting plate 232 and the first connecting plate 231 remains fixed after sliding, and further facilitating the sliding cylinder body 21 to slide along the pipe body 11.

[0055] As Figure 7As shown in the figure, the sliding assembly 24 includes a plurality of rollers 241 disposed between the sliding cylinder 21 and the pipe body 11. The rollers 241 are rotatably connected to the sliding cylinder 21, and the outer sides of the rollers 241 are in contact with the outer wall of the pipe body 11.

[0056] It should be noted that there is a gap between the inner wall of the sliding cylinder 21 and the outer wall of the pipe body 11. A groove is provided at a position on the inner wall of the sliding cylinder 21 close to the second slider 421. A part of the second slider 421 is received inside the groove, and another part of the second slider 421 extends outside the groove and is in contact with the outer wall of the pipe body 11.

[0057] According to the above structure, when the sliding cylinder 21 slides along the pipe body 11, the sliding assembly 24 rolls along the outer wall of the pipe body 11 and rotates on the sliding cylinder 21 at the same time, reducing the friction between the sliding cylinder 21 and the pipe body 11 during the sliding process of the sliding cylinder 21, making the sliding process of the sliding cylinder 21 along the pipe body 11 more stable.

[0058] As Figure 8 and Figure 13 shown in the figure, the inner wall measuring mechanism 30 includes a sliding column 32 disposed inside the pipe body 11. Both ends of the sliding column 32 are fixedly connected to the pipe body 11. A first slider 33 is slidably connected to the outside of the sliding column 32. A sliding arm 34 is slidably connected to one side of the first slider 33. The temperature measuring probe 31 is fixedly connected to one end of the sliding arm 34. A first spring 35 is fixedly connected between one end of the sliding arm 34 close to the temperature measuring probe 31 and the first slider 33. A first anti-wear assembly 36 is provided between one end of the sliding arm 34 far from the temperature measuring probe 31 and the sliding cylinder 21. A self-locking assembly 37 is provided between the sliding arm 34 and the pipe body 11.

[0059] It should be noted that both ends of the sliding column 32 are welded to the pipe body 11.

[0060] According to the above structure, when it is necessary to adjust the temperature measuring position of the temperature measuring probe 31 on the tube body 11, the first anti-wear component 36 drives the sliding arm 34 to move along the first slider 33 to the end away from the temperature measuring probe 31, so that the temperature measuring probe 31 is separated from the inner wall of the tube body 11, thereby reducing the damage caused by friction with the inner wall of the tube body 11 during the sliding process of the temperature measuring probe 31. At this time, the first spring 35 is compressed and the height is reduced. The sliding arm 34 drives the self-locking component 37 to move during the movement, so that the self-locking component 37 releases the limit of the tube body 11 and the sliding arm 34, and the sliding cylinder 21 is moved along the tube body 11. 1 slides, the sliding cylinder 21 drives the sliding arm 34 to slide along the sliding column 32 through the first anti-wear component 36, and the sliding arm 34 drives the temperature measuring probe 31 to slide along the pipe body 11, so that the temperature measuring probe 31 moves to a suitable temperature measuring position on the pipe body 11. After the first anti-wear component 36 is actuated, it no longer drives the sliding arm 34 to move. The first spring 35 restores its height under the elastic action and pushes the sliding arm 34 to move along the end of the first slider 33 close to the temperature measuring probe 31, so that the temperature measuring probe 31 contacts the inner wall of the pipe body 11 to measure the temperature of the inner wall of the pipe body 11, thereby adjusting the temperature measuring position of the temperature measuring probe 31 on the pipe body 11.

[0061] If Figure 9 As shown in FIG. 1 , the first anti-wear component 36 includes an attraction block 361 fixedly connected to the end of the sliding arm 34 away from the temperature measuring probe 31 , an electromagnet 362 is provided between the attraction block 361 and the sliding cylinder 21 , and the electromagnet 362 is fixedly connected to the sliding cylinder 21 .

[0062] It should be noted that the electromagnet 362 is in an arc shape, which is convenient for sliding along the outer wall of the tube body 11.

[0063] According to the above structure, when it is necessary to drive the sliding arm 34 to move through the first anti-wear component 36, the electromagnet 362 operates to attract the attraction block 361 to move to the side close to the electromagnet 362, and the attraction block 361 drives the temperature measuring probe 31 to separate from the inner wall of the tube body 11 through the sliding arm 34, thereby reducing the wear of the temperature measuring probe 31. At this time, after the sliding cylinder 21 is moved, the sliding cylinder 21 drives the electromagnet 362 to move along the tube body 11, and the attraction block 361 is attracted by the electromagnet 362 and drives the sliding arm 34 to move with the electromagnet 362, thereby adjusting the position of the sliding arm 34 and the temperature measuring probe 31 inside the tube body 11. When the temperature measuring position of the temperature measuring probe 31 is adjusted, the electromagnet 362 operates to no longer attract the attraction block 361 to move, and the first spring 35 drives the sliding arm 34 to move under the elastic action, so that a gap is generated between the attraction block 361 and the inner wall of the tube body 11. At this time, after the electromagnet 362 is moved, the attraction block 361 is no longer driven to move.

[0064] ​​Based on this, through the attraction between the electromagnet 362 and the attraction block 361, the purpose of moving the inner wall measuring mechanism 30 inside from the outside of the pipe body 11 is achieved. At the same time, during the movement, it is also convenient to reduce the wear of the temperature measuring probe 31 and improve the efficiency and convenience of temperature measurement.

[0065] As Figure 9 and Figure 10 shown, the self-locking assembly 37 includes a limit plate 371 fixedly connected to the sliding arm 34. First inclined surfaces 372 are provided on both sides of the limit plate 371. Slide rods 331 are fixedly connected to both ends of the first slider 33. A sliding sleeve 373 is slidably connected to the outside of the slide rods 331. A top block 374 is fixedly connected to one end of the sliding sleeve 373 close to the inner wall of the pipe body 11. A second inclined surface 375 is fixedly connected to one side of the sliding sleeve 373 close to the limit plate 371. The second inclined surface 375 is in contact with the first inclined surface 372.

[0066] It should be noted that both the first inclined surface 372 and the second inclined surface 375 are inclined slopes. A tension spring (not shown in the figure) is provided between the slide rod 331 and the sliding sleeve 373 for sliding the sliding sleeve 373 inward to reset.

[0067] According to the above structure, during the process of the sliding arm 34 moving along the first slider 33 away from the temperature measuring probe 31, the sliding arm 34 drives the limit plate 371 to move away from the temperature measuring probe 31, so that the second inclined surface 375 slides inward along the first inclined surface 372. The second inclined surface 375 drives the sliding sleeve 373 to slide inward along the slide rod 331. The sliding sleeve 373 drives the top block 374 to disengage from the inner wall of the pipe body 11, so that the limit between the self-locking assembly 37 and the pipe body 11 is released. During the process of the sliding arm 34 moving along the first slider 33 towards the temperature measuring probe 31, the first spring 35 drives the sliding arm 34 to drive the limit plate 371 to move towards the temperature measuring probe 31, so that the second inclined surface 375 slides outward along the first inclined surface 372. The second inclined surface 375 drives the sliding sleeve 373 to slide outward along the slide rod 331. The sliding sleeve 373 drives the top block 374 to press tightly against the inner wall of the pipe body 11, forming a limit between the self-locking assembly 37 and the pipe body 11.

[0068] Based on this, during the process of the first anti-wear assembly 36 driving the sliding arm 34 to move, the self-locking assembly 37 acts with the movement of the sliding arm 34 to realize the limitation or release of the limit between the self-locking assembly 37 and the pipe body 11, so as to facilitate keeping the measuring position of the temperature measuring probe 31 fixed or releasing the fixation on the pipe body 11.

[0069] As Figure 11 and Figure 13As shown in the figure, the outer wall measuring mechanism 40 includes a second anti-wear component 42 slidably installed inside the sliding cylinder 21. A temperature measuring piece 43 is provided between the sliding cylinder 21 and the pipe body 11. The temperature measuring piece 43 is fixedly connected to the end of the second anti-wear component 42. There are two impurity removing components 41, which are respectively located on both sides of the second anti-wear component 42. The impurity removing component 41 is fixedly connected to the sliding cylinder 21.

[0070] It should be noted that the temperature measuring piece 43 is arc-shaped.

[0071] According to the above structure, when it is necessary to adjust the temperature measuring position of the outer wall measuring mechanism 40 on the pipe body 11, after the second anti-wear component 42 acts, it drives the temperature measuring piece 43 to move outward, so that the temperature measuring piece 43 is separated from the outer wall of the pipe body 11, reducing the situation that the temperature measuring piece 43 is damaged due to friction between the temperature measuring piece 43 and the outer wall of the pipe body 11. Slide the sliding cylinder 21 along the pipe body 11. The sliding cylinder 21 drives the temperature measuring piece 43 to move along the pipe body 11, so that after the temperature measuring piece 43 moves to a suitable temperature measuring position, it measures the temperature of the outer wall of the pipe body 11. Thus, it is convenient to adjust the temperature measuring position of the outer wall measuring mechanism 40 on the pipe body 11. In this process, the impurity removing component 41 moves with the movement of the sliding cylinder 21 to remove dust and other impurities attached to the outer wall of the pipe body 11. It is convenient for the impurity removing component 41 to remove the impurities at the positions on both sides of the temperature measuring piece 43 on the outer wall of the pipe body 11 during the movement of the temperature measuring piece 43, reducing the situation that impurities enter between the temperature measuring piece 43 and the outer wall of the pipe body 11 and hinder the temperature measuring piece 43 from fitting with the pipe body 11, and improving the reliability of temperature measurement.

[0072] As Figure 12 shown in the figure, the impurity removing component 41 includes a mounting plate 411 fixedly connected to the sliding cylinder 21. A plurality of cleaning rollers 412 are rotatably connected to the mounting plate 411. The outer sides of the cleaning rollers 412 are in contact with the outer wall of the pipe body 11.

[0073] It should be noted that there are three cleaning rollers 412, which are evenly distributed along the outer wall of the pipe body 11.

[0074] According to the above structure, when the sliding cylinder 21 drives the impurity removing component 41 to move, the sliding cylinder 21 drives the cleaning rollers 412 to move along the outer wall of the pipe body 11 through the mounting plate 411. At the same time, the cleaning rollers 412 also roll along the outer wall of the pipe body 11, which is convenient for the cleaning rollers 412 to remove dust and other impurities attached to the pipe body 11 and improves the efficiency of impurity removal.

[0075] As Figure 12 shown in the figure, the second anti-wear component 42 includes a second slider 421 slidably connected to the sliding cylinder 21. One end of the second slider 421 close to the pipe body 11 is fixedly connected to the temperature measuring piece 43. A second spring 422 is fixedly connected between the end of the second slider 421 far from the pipe body 11 and the sliding cylinder 21.

[0076] It should be noted that a convex portion is fixedly provided at the top of the second anti-wear component 42 near one side of the second spring 422, and the convex portion extends out of the outer part of the sliding cylinder body 21, facilitating the operator to slide the second anti-wear component 42 by sliding the convex portion.

[0077] According to the above structure, when it is necessary to move the temperature measuring piece 43 along the pipe body 11, the operator moves the second anti-wear component 42 outward, and the second anti-wear component 42 drives the temperature measuring piece 43 to move outward, so that a gap is generated between the second anti-wear component 42 and the temperature measuring piece 43, reducing the friction between the temperature measuring piece 43 and the outer wall of the pipe body 11. At this time, the second spring 422 is compressed and its height is reduced. When it is not necessary to move the temperature measuring piece 43 along the pipe body 11, the operator no longer moves the second anti-wear component 42, and the second spring 422 recovers its height under the elastic action and pushes the second anti-wear component 42 to move inward, and the second anti-wear component 42 drives the temperature measuring piece 43 to stick to the outer wall of the pipe body 11, thus facilitating the reset of the temperature measuring piece 43.

[0078] The working principle of the present invention is as follows: There are two sliding cylinder bodies 21. After the connecting frame mechanism 20 acts, the relative positions between the two sliding cylinder bodies 21 are adjusted, facilitating the simultaneous temperature measurement of the pipe body 11 by the inner wall measurement mechanism 30 and the outer wall measurement mechanism 40 in the two sliding cylinder bodies 21 to obtain a temperature difference, which is convenient for helping to judge whether the engine is in a normal working state and improving the efficiency of temperature measurement. The sliding cylinder body 21 slides along the pipe body 11 to adjust the temperature measurement positions of the inner wall measurement mechanism 30 and the outer wall measurement mechanism 40, improving the convenience of temperature measurement. Among them, when the sliding cylinder body 21 slides, the temperature measurement position of the temperature measurement probe 31 on the inner wall of the pipe body 11 is adjusted through the first anti-wear component 36. When the sliding cylinder body 21 slides, it drives the temperature measuring piece 43 to move to adjust the temperature measurement position of the temperature measuring piece 43 on the outer wall of the pipe body 11. At the same time, the sliding cylinder body 21 also drives the impurity removal component 41 to slide along the outer wall of the pipe body 11 to remove impurities such as dust attached to the outer wall of the pipe body 11, reducing the influence of impurities on the fitting of the temperature measuring piece 43 and the pipe body 11 and improving the reliability of temperature measurement.

[0079] The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention. The structures, devices, and operation methods not specifically described and explained in the present invention, unless otherwise specifically stated and limited, are implemented according to the conventional means in the art.
