[0034] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0035] Reference below Figure 1-Figure 7 A sediment thickness measuring device 100 according to an embodiment of the present invention is described.

[0036] like Figure 1-Figure 3 As shown, a sediment thickness measuring device 100 according to an embodiment of the present invention includes: a device housing 1, a positioning base 2 and a detection member 3, the positioning base 2 includes a plurality of positioning members 21, one end of each of the plurality of positioning members 21 is connected to the device housing 1, and the other ends of the plurality of positioning members 21 are coplanar with a reference plane, the detection member 3 is arranged in the device housing 1, the detection member 3 can move along the normal direction of the reference plane, or the detection member 3 can emit a detection signal 34 along the normal direction of the reference plane and can receive the detection signal 34 to measure the sediment thickness.

[0037] Among them, the sediment thickness measuring device 100 can be used to measure the sediment thickness of the automobile engine oil pan 200. For example, the sediment thickness measuring device 100 can be used to measure the thickness of the sludge 9 of the automobile engine oil pan 200. This article takes the sediment thickness measuring device 100 as an example to describe the measurement of the thickness of the sludge 9 of the automobile engine oil pan 200. In addition, the sediment thickness measuring device 100 proposed in the present invention is often used when the thickness of the sludge 9 at the automobile engine oil pan 200 is less than Class C (0.198 mm). The thickness of the sludge 9 below Class C can be measured more accurately, and the measurement result is objective, accurate, and easy to operate.

[0038] The positioning base 2 of the sediment thickness measuring device 100 includes a plurality of positioning members 21, the number of which may be but is not limited to three, four, five, etc., one end of each of the plurality of positioning members 21 can be connected to the device housing 1 of the sediment thickness measuring device 100, the other ends of each of the plurality of positioning members 21 can be coplanar with the reference plane, and the other ends of each of the plurality of positioning members 21 can be inserted into the sludge 9 and abut against the oil pan, so that the sediment thickness measuring device 100 can be stably fixed in the sludge 9 of the oil pan for subsequent sludge 9 thickness measurement operations.

[0039] As some embodiments of the present application, the cross-section of the device housing 1 can be configured as a circle, a square, a triangle, etc., to meet different measurement environments and improve the applicability of the sediment thickness measuring device 100 .

[0040] As some embodiments of the present application, a plurality of positioning members 21 are integrally formed with the device housing 1 or are detachably connected thereto.

[0041] like Figure 2 As shown, the probe 3 can be constructed as a mechanical probe, and the probe 3 is arranged on the device housing 1. The probe 3 can move along the normal direction of the reference plane, so that the end face of the probe 3 close to the reference plane is always parallel to the reference plane. The probe 3 can vertically approach the upper surface 91 of the sludge and finally contact the upper surface 91 of the sludge. At this time, the distance between the end face of the probe 3 and the reference plane is the thickness of the sludge 9. By making the probe 3 vertically approach the upper surface 91 of the sludge, the error caused by factors such as disturbance and vibration of the upper surface 91 of the sludge can be reduced, and the error caused by the tilt of the end face of the probe 3 can also be reduced, so that the measurement environment is relatively stable and the accuracy of the measurement result is improved.

[0042] Or, if Figure 3 As shown, the detection member 3 can be constructed as a signal distance measuring device, such as an ultrasonic rangefinder, a laser rangefinder, an electronic automatic rangefinder, etc. The detection member 3 can emit a detection signal 34 along the normal direction of the reference plane and can receive the reflected detection signal 34 to measure the distance between the detection member 3 and the upper surface 91 of the sludge from the vertical direction, and then the thickness of the sludge 9 can be obtained. By constructing the detection member 3 as a signal distance measuring device, the accuracy of the measurement result can be improved, and the operation is convenient, which can reduce the difficulty of the measurement personnel's work and improve the work efficiency.

[0043] In the above embodiment, by setting a plurality of positioning members 21, the amplitude of the sediment disturbance by the sediment thickness measuring device 100 can be reduced, so that the design of the detection member 3 being vertically close to the upper surface of the sediment or the detection member 3 transmitting the signal along the normal of the reference plane can reduce the error caused by factors such as disturbance and vibration on the upper surface of the sediment, and can also reduce the error caused by the inclination of the end face of the detection member 3 or the deviation of the direction of the signal emitted by the detection member 3 from the normal of the reference plane, so as to make the measurement environment relatively stable and improve the accuracy of the measurement result.

[0044] In an embodiment of the present invention, Figure 1 As shown, the sediment thickness measuring device 100 further includes: an adjusting member 4, which is disposed in the device housing 1 and is in transmission cooperation with the detection member 3, and the adjusting member 4 can drive the detection member 3 to move along the normal direction of the reference plane.

[0045] Among them, the adjusting part 4 of the sediment thickness measuring device 100 can be arranged on the device housing 1, and at least part of the structure of the adjusting part 4 can be moved along the normal direction of the reference plane. The adjusting part 4 can cooperate with the detection part 3 in transmission. When at least part of the structure of the adjusting part 4 moves toward the direction of the detection part 3, the adjusting part 4 can drive the detection part 3 to move along the normal direction of the reference plane, so that the detection part 3 can be vertically close to the upper surface 91 of the sludge, which can reduce the error caused by the inclination of the end face of the detection part 3, improve the accuracy of the measurement result, and the operation is simple and convenient.

[0046] As some embodiments of the present application, the adjusting member 4 can be abutted and matched with the detecting member 3 so that the adjusting member 4 and the detecting member 3 can be transmitted and matched. Specifically, since the adjusting member 4 and the detecting member 3 are abutted and matched, the adjusting member 4 can drive the detecting member 3 to move vertically close to the upper surface 91 of the oil mud, and an elastic structure can be set to drive the detecting member 3 to move vertically away from the upper surface 91 of the oil mud. Such a structure is simple and easy to install, and it is convenient to design and manufacture the adjusting member 4 and the detecting member 3.

[0047] As some embodiments of the present application, the adjusting member 4 can be welded, snap-connected or bolted to the detecting member 3. Such a setting can drive the detecting member 3 to move synchronously by moving the adjusting member 4, and the fixed connection can enhance the transmission effect of the adjusting member 4 and the detecting member 3 and improve the reliability of use.

[0048] In an embodiment of the present invention, Figure 1 As shown, the adjusting member 4 includes: a first matching portion 41 and an adjusting portion 42, one end of the first matching portion 41 is connected to the adjusting portion 42, the other end of the first matching portion 41 is transmission-matched with the detecting member 3, the device housing 1 defines a matching hole 11, the first matching portion 41 is passed through the matching hole 11 and is threadedly matched with the matching hole 11, and the adjusting portion 42 is located outside the device housing 1.

[0049] Among them, one end of the first matching part 41 of the adjusting part 4 can be connected to the adjusting part 42 of the adjusting part 4, and the other end of the first matching part 41 can be transmitted and matched with the detection part 3. The measurement personnel can drive the first matching part 41 by operating the adjusting part 42, and then drive the detection part 3 to move along the normal direction of the reference plane. The adjusting part 42 can be located on the outside of the device shell 1 to facilitate the measurement personnel to operate.

[0050] The device shell 1 can define a mating hole 11, and the mating hole 11 can have an internal thread. The first mating portion 41 has an external thread that can be matched with the internal thread of the mating hole 11. The first mating portion 41 can be inserted into the mating hole 11 and be threadedly matched with the mating hole 11. This arrangement can accurately control the distance that the detection member 3 needs to travel along the normal direction of the reference plane to approach the upper surface 91 of the sludge, so as to reduce the risk of excessive contact between the end face of the detection member 3 and the upper surface 91 of the sludge (excessive contact means that the end face of the detection member 3 is pressed into the sludge 9, causing the height of the upper surface 91 of the sludge to change). In addition, the mating hole 11 can guide the moving direction of the first mating portion 41, reducing the risk of displacement and tilt of the adjustment member 4, so as to improve the controllability and reliability of the sediment thickness measuring device 100, which is conducive to improving the accuracy of the measurement results.

[0051] In an embodiment of the present invention, Figure 1 As shown, the detection member 3 includes: a detection body 31, a detection portion 32 and a second matching portion 33. The detection portion 32 and the second matching portion 33 are respectively arranged at both ends of the detection body 31. The device shell 1 defines an installation space 12 connected to the matching hole 11. The second matching portion 33 is located in the installation space 12. Part of the structure of the first matching portion 41 is located in the installation space 12 and abuts against the second matching portion 33.

[0052] Among them, the device housing 1 can define an installation space 12 connected to the matching hole 11, a part of the structure of the first matching part 41 can be located in the installation space 12, the second matching part 33 of the detection member 3 can be arranged at one end of the detection body 31 and located in the installation space 12, the second matching part 33 can be abutted with the first matching part 41, the detection part 32 of the detection member 3 can be arranged at the other end of the detection body 31, the detection part 32 can have a detection end face 321, the detection end face 321 is the surface of the detection part 32 away from the detection body 31, the detection part 32 can be close to the upper surface 91 of the sludge, the detection end face 321 can contact with the upper surface 91 of the sludge, and then the thickness of the sludge 9 can be known by the distance between the detection end face 321 and the reference plane, the measurement principle is simple, the operation is convenient and the result is accurate. In addition, such a setting can make the adjustment member 4 abut and match with the detection member 3, the structure is simple, the installation is convenient, and it is easy to design and manufacture the adjustment member 4 and the detection member 3.

[0053] In addition, the matching hole 11 has a guiding effect on the moving direction of the adjusting member 4, and the installation space 12 can have a guiding effect on the moving direction of the detection member 3, so that the adjusting member 4 and the detection member 3 can both move along the normal direction of the reference plane, so that the detection part 32 can be vertically close to the upper surface 91 of the mud, so as to reduce the error caused by the inclination of the detection end face 321, make the measurement environment relatively stable, and improve the accuracy of the measurement result.

[0054] In an embodiment of the present invention, Figure 1 As shown, the sediment thickness measuring device 100 also includes: an elastic member 5, the cross-sectional area of ​​the second matching portion 33 is larger than the cross-sectional area of ​​the detection body 31, the elastic member 5 is sleeved on the detection body 31 and is compressed between the second matching portion 33 and the wall of the installation space 12 away from the adjustment portion 42.

[0055] The elastic member 5 is arranged in the installation space 12, and the elastic member 5 can be constructed as a spring. The cross-sectional area of ​​the detection body 31 can be smaller than the cross-sectional area of ​​the second matching portion 33. The elastic member 5 can be sleeved on the detection body 31, and one end of the elastic member 5 can abut against the end surface of the second matching portion 33 close to the detection body 31, and the other end of the elastic member 5 can abut against the wall surface of the installation space 12 away from the adjustment portion 42, so that the elastic member 5 can be compressed between the second matching portion 33 and the wall surface of the installation space 12 away from the adjustment portion 42. When the first matching portion 41 moves toward the direction of the elastic member 5, the first matching portion 41 drives the detection member 3 to move vertically close to the upper surface 91 of the sludge. In this process, the elastic member 5 is compressed. Then, when the first matching portion 41 moves in the direction away from the elastic member 5, the compressed elastic member 5 can drive the detection member 3 to move toward the first matching portion 41. By providing the elastic member 5, the movement of the detection member 3 can be smooth and stable, and the operability of the sediment thickness measuring device 100 can be improved. Furthermore, the detection body 31 has a guiding effect on the compression and extension of the elastic member 5 , which can reduce the error caused by the inclination of the elastic member 5 and improve the accuracy of the measurement result.

[0056] In an embodiment of the present invention, Figure 4 As shown, the detection portion 32 is located between the plurality of positioning members 21 , and the detection portion 32 and the plurality of positioning members 21 are spaced apart from each other.

[0057] Among them, multiple positioning members 21 can be arranged along the circumference of the device housing 1, the detection part 32 can be located between the multiple positioning members 21, and the detection part 32 and the multiple positioning members 21 are spaced apart. When the multiple positioning members 21 are inserted into the sludge 9 of the engine oil pan 200, the sludge 9 will be disturbed and vibrated, which will cause the thickness of the sludge 9 near the multiple positioning members 21 to change. By designing a structural form in which the detection part 32 is located between the multiple positioning members 21, and the detection part 32 and the multiple positioning members 21 are spaced apart, the risk of the change in the thickness of the sludge 9 caused by the insertion of multiple positioning members 21 into the sludge 9 being transmitted to the contact point between the detection end face 321 and the sludge upper surface 91 can be reduced, and the change in the thickness of the sludge 9 at the contact point between the detection end face 321 and the sludge upper surface 91 can be reduced, so that the measurement environment is relatively stable and the accuracy of the measurement result is improved.

[0058] In an embodiment of the present invention, Figure 4 As shown, the surface of the detection portion 32 away from the detection body 31 is circular.

[0059] Among them, the above-mentioned detection end face 321 is the surface of the detection part 32 away from the detection body 31. The detection end face 321 can be constructed into a circle. The circular detection end face 321 has the greatest compactness, that is, the ratio of the circumference of the circular detection end face 321 to the area is the smallest, so that the detection end face 321 has a relatively small volume and a larger detection end face 321, reducing the risk of the thickness change of the sludge 9 caused by the insertion of multiple positioning parts 21 into the sludge 9 being transmitted to the contact point between the detection end face 321 and the sludge upper surface 91, and the circular detection end face 321 can facilitate observation of whether the detection end face 321 is in contact with the sludge upper surface 91, facilitate measurement, and improve the accuracy of the measurement results.

[0060] As some embodiments of the present application, Figure 5 As shown, the end face of the adjusting portion 42 away from the first matching portion 41 has a plurality of scales 422, and the plurality of scales 422 include a "0" scale line 423. The plurality of scales 422 can represent different values ​​according to actual conditions. For example, there can be a total of 40 scales 422, and the pitch of the external thread of the first matching portion 41 can be 0.2 mm. Then, each rotation of the adjusting portion 42 by one scale 422 represents that the detection portion 32 moves 0.005 mm along the normal direction of the reference plane. The distance moved by the adjusting portion 42 along the normal direction of the reference plane can be determined by the number of rotated scales 422, and further the distance moved by the detection member 3 along the normal direction of the reference plane can be determined, so that the measurement result can be obtained more easily, the measurement result is more accurate, and the operation is simple.

[0061] As some embodiments of the present invention, multiple scales 422 can be marked as 0, 1 / 4A,..., C grade, etc. When the adjusting part 42 is rotated to make the detection end face 321 contact with the upper surface 91 of the sludge, the thickness grade type of the measured sludge 9 can be directly known from the scale 422 of the adjusting part 42. This design is more intuitive and simpler.

[0062] In an embodiment of the present invention, Figure 6 and Figure 7 As shown, the sediment thickness measuring device 100 may further include: a reference member 6 rotatably disposed on the device housing 1 and having a reference mark 61 , and along the normal direction of the reference plane, the reference member 6 is correspondingly disposed with the adjustment portion 42 .

[0063] Among them, the reference part 6 of the sediment thickness measuring device 100 is rotatably arranged on the device housing 1, and a reference mark 61 may be provided on the reference part 6. Along the normal direction of the reference plane, the reference part 6 may be arranged corresponding to the adjustment part 42, and the side wall of the adjustment part 42 may have a calibration mark 421. Along the normal direction of the reference plane, the calibration mark 421 is aligned with the "0" scale line 423. When the sediment thickness measuring device 100 is calibrated, the reference mark 61 and the calibration mark 421 can be aligned. By setting the reference part 6 with the reference mark 61, the sediment thickness measuring device 100 can be calibrated to ensure the measurement accuracy of the sediment thickness measuring device 100.

[0064] The sediment thickness measuring device 100 needs to be calibrated before use, such as Figure 6 and Figure 7 As shown, when calibrating the sediment thickness measuring device 100, the reference mark 61 and the calibration mark 421 can be aligned first. At this time, a micrometer can be used to measure the distance between the reference plane and the detection end face 321 along the normal direction of the reference plane. If the distance is 0, it proves that the sediment thickness measuring device 100 is calibrated. If the distance is not 0, the adjustment part 42 can be rotated to drive the detection member 3 to make the reference plane and the detection end face 321 flush (that is, to make the above distance 0). At this time, the calibration mark 421 has changed its position compared to before the adjustment part 42 was rotated. Then, the reference member 6 can be rotated to align the reference mark 61 and the calibration mark 421, and the calibration operation of the sediment thickness measuring device 100 is completed. The calibration operation can make the measured results of the sediment thickness measuring device 100 more objective and accurate, and can greatly improve the service life and reliability of the sediment thickness measuring device 100.

[0065] In an embodiment of the present invention, Figure 4 As shown, a plurality of positioning members 21 are disposed around, and / or a surface of the positioning member 21 away from the device housing 1 is a curved surface.

[0066] Among them, multiple positioning members 21 can be arranged around the circumference of the device shell 1. Further, multiple positioning members 21 can be evenly arranged around the circumference of the device shell 1, so that the sediment thickness measuring device 100 can be stably fixed in the sludge 9 of the oil pan for subsequent measurement operations.

[0067] The surface of the positioning member 21 away from the device housing 1 can be constructed as an arc surface, which can be a circular arc surface, an elliptical arc surface or an irregular arc surface. This setting can reduce the degree of disturbance and vibration caused to the upper surface 91 of the sludge when the positioning member 21 is inserted into the sludge 9, so as to make the measurement environment relatively stable and improve the accuracy of the measurement results.

[0068] In an embodiment of the present invention, Figure 3 As shown, the sediment thickness measuring device 100 also includes: a calculation module 7 and a display screen 8, both of which are arranged in the device housing 1, the calculation module 7 is connected to the detection member 3, the calculation module 7 is used to calculate the spacing distance between the detection member 3 and the reference plane to determine the sediment thickness, or the detection member 3 can receive the detection signal 34 and transmit it to the calculation module 7, the calculation module 7 is used to determine the sediment thickness according to the detection signal 34, and the display screen 8 is used to display the sediment thickness.

[0069] Among them, the calculation module 7 and the display screen 8 of the sediment thickness measuring device 100 can be arranged in the device housing 1, the calculation module 7 can be connected to the detection member 3, the calculation module 7 can be used to calculate the interval distance between the detection member 3 and the reference plane, the calculation module 7 can calculate the initial distance L0 between the detection member 3 and the reference plane before measurement, and the calculation module 7 can also calculate the measured distance L1 between the detection member 3 and the reference plane when the detection end face 321 contacts the upper surface 91 of the sludge. The difference between L0 and L1 is the thickness of the sludge 9. L0, L1, and the difference between L0 and L1 can all be displayed on the display screen 8 of the sediment thickness measuring device 100, so that the measurement personnel can intuitively know the thickness of the sludge 9, simplify the measurement operation steps, reduce the measurement difficulty, and improve the accuracy of the measurement results.

[0070] For example, before conducting a test, the calculation module 7 can calculate the initial distance L0 between the detection member 3 and the reference plane before measurement by pressing or touching the operation button. Then, the detection member 3 can be driven to move along the normal direction of the reference plane by operating the adjustment part 42. When the detection end face 321 contacts the upper surface 91 of the mud, the calculation module 7 can calculate the measured distance L1 between the detection member 3 and the reference plane at this time by pressing or touching the operation button, and calculate the difference between L0 and L1. It can be understood that by setting a distance displacement sensor to detect the displacement of the detection part 32 or the adjustment part 42 or the first matching part 41 or the second matching part 33, the distance between the detection member 3 and the reference plane can be obtained.

[0071] Alternatively, the detection element 3 can emit a detection signal 34 along the normal direction of the reference plane and receive the reflected detection signal 34. The detection element 3 can transmit the relevant information of the detection signal 34 to the calculation module 7. The calculation module 7 can calculate the distance L2 traveled by the detection signal 34 from the detection element 3 to the upper surface 91 of the sludge. The difference between L0 and L2 is the thickness of the sludge 9.
