[0002] The main function of the oil tank is to store oil. For some oil tanks on machinery, especially those on some precision machines, some require the oil to be of high cleanliness. If the oil is not clean enough, it may affect the normal use of the machine and even cause damage to the machine. Traditional inspections mostly test the oil and ignore the inspection of the oil tank. If the oil tank is not clean enough, the oil quality cannot achieve the expected effect after cleaning. The inspection of the cleanliness of the oil tank is generally carried out by taking pictures with 3D visual equipment.

[0033] The sealing shell 12 is provided with an installation cavity 121 inside, and a partition plate 122 is provided between the side walls at both ends of the installation cavity 121, and a positioning shaft 123 is movably provided at the middle of the partition plate 122, and a winding roller 124 is fixedly connected between the positioning shafts 123, and a first spring spring 125 is fixedly connected to the outer wall of the positioning shaft 123 at one end of the winding roller 124, and a sleeve 126 is fixedly connected to the side wall of the partition plate 122 outside the first spring spring 125, and the sleeve 126 surrounds the outside of the first spring spring 125, and the inner wall of one side of the sleeve 126 is fixedly connected to the outer end of the first spring spring 125, and the winding roller 124 is away from the sleeve 12 6 is internally embedded with an adapter 32, which passes through the positioning shaft 123 on the same side and extends to the outside thereof. A conductive ring 127 is fixedly connected to the inner wall of the installation cavity 121 opposite to the adapter 32. The conductive ring 127 is electrically connected to the touch screen controller 1 through a wire. The end of the adapter 32 is plugged into the conductive ring 127. One end of the detection cable 3 is fixedly connected to the adapter 32, and the other end extends through and extends to the outside of the winding roller 124 and is wound on its outer wall. A plurality of positioning rings 128 are fixedly connected to the inner wall of the installation cavity 121 on one side of the guide cylinder 2. The detection cable 3 is inserted into the positioning ring 128 and then extends into the guide cylinder 2.

[0034] The detection probe 33 includes a mounting head 331 fixedly connected to the end of the detection cable 3 outside the guide cylinder 2, and a camera 332 and a lighting bulb 333 are fixedly connected to the outer wall of the mounting head 331 in sequence. A transparent isolation cover 334 is fixedly connected to the outer wall of the mounting head 331 outside the camera 332 and the lighting bulb 333, and the transparent isolation cover 334 is made of acrylic board material.

[0035] The winding column 6 includes a movable shaft 61 movably connected to the outer wall of the limit plate 4 and a second clockwork spring 62 wound on the outer wall of the movable shaft 61. A protective cover 63 is fixedly connected to the outer wall of the limit plate 4 outside the second clockwork spring 62. The movable shaft 61 extends through and extends to the outside of the protective cover 63. The rear end is fixedly connected to a rotating column 64. The rear end of the rotating column 64 is fixedly connected to a positioning plate 65. The main control rope 5 is wound and reeled on the outer wall of the rotating column 64. The rear end movably passes through the positioning plate 65. The rear end of the main control rope 5 outside the positioning plate 65 is fixedly connected to a pull ring 51. When the main control rope 5 is completely reeled on the outer wall of the rotating column 64, the second clockwork spring 62 maintains a normal relaxed state. At this time, the counterweight block 31 is arranged to fit the outer wall of the end of the guide cylinder 2.

[0036] Specifically, the detection probe 33 is inserted into the top port of the engineering machinery oil tank, and the detection cable 3 at the end of the guide cylinder 2 is dragged by hand to drive the winding roller 124 inside the sealing shell 12 to rotate between the partition plates 122 based on the positioning shaft 123. The detection cable 3 rotates in the conductive ring 127 based on the adapter 32 at the end of the winding roller 124 and is connected to the touch screen controller 1. The winding roller 124 rotates to release the wound detection cable 3 and contracts the first spring 125 at the same time. After the detection cable 3 is pulled out of the guide cylinder 2, the detection probe 33 at the end is dragged to suspend inside the oil tank under the action of the gravity of the counterweight block 31. When the counterweight block 31 drags the detection cable 3 to move, it simultaneously drives the main control rope 5 on the outer wall of the winding column 6 to move into the oil tank until the two are released and completely lock the detection cable 3. At this time, the pull ring 51 at the tail of the main control rope 5 is pulled upwards, and the counterweight block 3 The detection cable 3 at the top of the detection cable 3 is kept stationary due to the influence of the gravity of the counterweight 31, so that the detection cable 3 between the detection probe 33 and the counterweight 31 is bent. The detection probe 33 is pushed by the main control rope 5 to drive the detection cable 3 to deflect based on the height of the lower end of the counterweight 31, thereby controlling the angle of the detection probe 33 to shoot and detect the inner wall of the oil tank. At the same time, the touch screen controller 1 is controlled to rotate at the top of the oil tank mouth, so that when the angle of the detection probe 33 changes, the side walls and the upper and lower bottom surfaces around the oil tank can be comprehensively visually photographed and inspected. The main control rope 5 is used to control the bending of the detection cable 3, so that a single person can conveniently control the cleanliness inspection of the inner wall of the oil tank, avoids the inconvenience of the existing detection equipment using a long lever structure to control the camera 332 to deflect and shoot in the oil tank, and relieves the heavy fatigue of the staff when holding it for a long time during the inspection. It is convenient and practical.

[0037] In order to ensure the stability of the detection cable 3 and the detection probe 33, Figure 2 , Figure 3 and Figure 6 As shown, this embodiment provides the following technical solutions:

[0038] The guide cylinder 2 includes a cylinder body 21 fixedly connected to the outer wall of the sealing shell 12 and a cap 22 movably clamped on the outer wall of the end of the cylinder body 21, the limit plates 4 are symmetrically distributed on the outer walls on both sides of the cap 22, elastic components 23 are fixedly connected between the inner walls on both sides of the cap 22 and the outer walls on both sides of the port of the cylinder body 21, an annular plate 24 is fixedly connected between the inner walls of the cylinder body 21, spring rods 25 are fixedly connected to the inner walls on both sides of the cylinder body 21 outside the annular plate 24, and locking rings 26 are fixedly connected to the ends of the spring rods 25, and guide wheels 27 are fixedly connected to the outer walls on both sides of the annular plate 24 and the inner walls on both sides of the cap 22, and adjusting ropes 28 are fixedly connected to the locking rings 26 on both sides of the cylinder body 21. The two sets of adjusting ropes 28 are S-shaped and wound around the outer wall of the guide wheel 27, and the ends are fixedly connected to the inner walls on both sides of the cylinder body 21.

[0039] When the elastic component 23 maintains a normal relaxed state, the locking rings 26 on both sides of the cylinder 21 are staggered. At this time, the spring rod 25 is in a compressed state. On the contrary, the two sets of locking rings 26 are coaxially arranged with the annular plate 24 and the middle hole on the cap 22. At this time, the detection cable 3 passes straight through the locking ring 26, the annular plate 24 and the middle hole on the cap 22.

[0040] Specifically, the portion of the detection cable 3 with the detection probe 33 and the counterweight 31 on the outside of the guide cylinder 2 is extended into the port of the engineering machinery tank. At this time, due to the action of the limit plates 4 on both sides of the cap 22, the touch screen controller 1 can be placed flat on the top of the engineering machinery tank port based on the restriction of the limit plates 4 on the engineering machinery tank port. The touch screen controller 1 uses its own gravity to push the cap 22 to compress the elastic component 23 based on the restriction of the limit plates 4, so that the cap 22 completely fits the protruding part of the bottom port of the cylinder 21. In this process, the distance between the guide wheels 27 in the cylinder 21 and the cap 22 becomes shorter, and the adjustment rope 28 is relaxed, so that the compressed spring rod 25 is extended. The spring rod 25 pushes the middle holes of the locking rings 26 on both sides of the cylinder 21 to align with the middle holes on the annular plate 24 and the cap 22, and the locking rings 26 release the staggered pulling lock on the detection cable 3. At this time, use the fingers of both hands to press on both sides of the cylinder 21 with the engineering machinery The unlocked detection cable 3 can be dragged alternately and continuously in the gap between the fuel tank ports, so that the detection cable 3 and the detection probe 33 are suspended into the fuel tank under the action of the counterweight block 31, so as to visually detect the cleanliness of the inner wall thereof. After the detection cable 3 is pulled and the touch screen controller 1 is lifted to disengage the cap 22 from the fuel tank port of the engineering machinery, the cap 22 is reset under the action of the elastic component 23, thereby pulling the adjustment rope 28 in the opposite direction to compress the spring rod 25, so that the locking ring 26 at the end of the spring rod 25 again pulls the detection cable 3 to both sides alternately, so as to realize the staggered locking restriction of the detection cable 3, and ensure the stability of the detection cable 3 when the main control rope 5 is adjusted by one hand. After pressing the cap 22 again, the detection cable 3 can be automatically reeled onto the outer wall of the reel-up roller 124 in the sealed housing 12 under the action of the first clockwork spring 125, so as to realize the automatic arrangement of the detection cable 3 after the detection is completed, which is convenient to use.

[0041] like Figure 2 , Figure 4 and Figure 7-Figure 8 As shown, in order to achieve fine control of the detection probe 33, this embodiment provides the following technical solutions:

[0042] An auxiliary component 7 is fixedly connected to the outer wall of the detection cable 3 between the counterweight block 31 and the detection probe 33, and the auxiliary component 7 includes a chuck 71 fixedly connected to the outer wall of the detection cable 3 and a fixed block 711 fixedly connected to the side wall of the chuck 71, a deflection rod 72 is movably connected to the bottom of the end of the fixed block 711, a torsion spring 712 is fixedly connected between the side wall of the deflection rod 72 and the bottom plate of the fixed block 711, an auxiliary control rope 73 is fixedly connected to the side wall of the deflection rod 72 outside the torsion spring 712, and the auxiliary control rope 73 movably passes through the chuck 71 and then is reeled and wound around the outer wall of the winding column 6 on the limit plate 4 away from the side of the main control rope 5, a fixed rod 74 is fixedly connected to the side wall of the deflection rod 72 outside the auxiliary control rope 73, and a ring 75 arranged around the detection cable 3 is fixedly connected to the end of the fixed rod 74, a deflection head 76 is movably provided at the end of the deflection rod 72, and a detection swab 77 is movably connected to the end of the deflection head 76.

[0043] The setting method of the auxiliary control rope 73 and the winding column 6 is the same as the setting method of the main control rope 5 and the winding column 6. After the auxiliary control rope 73 and the main control rope 5 are movably passed through the limit plates 4 on both sides of the guide cylinder 2, the auxiliary control rope 73 and the main control rope 5 are respectively wound and rolled up on the outer wall of the rotating column 64 on the limit plates 4 on both sides of the guide cylinder 2, and after the end of the auxiliary control rope 73 passes through the positioning plate 65 at the end of the rotating column 64 on the same side, the end of the auxiliary control rope 73 is fixedly connected to the pull ring 51.

[0044] Specifically, after the bending control of the detection cable 3 at the bottom of the counterweight 31 is completed by pulling the main control rope 5, one hand holds the main control rope 5 and the touch screen controller 1 to keep the angle of the detection probe 33 stable, and the other hand pulls the pull ring 51 at the top of the auxiliary control rope 73. The auxiliary control rope 73 pulls the deflection rod 72 to deflect based on the bottom of the end of the fixed block 711 and compresses the torsion spring 712. When the deflection rod 72 deflects and approaches the detection probe 33, the detection probe 33 at the detection probe 33 is squeezed and pushed by the cooperation of the fixed rod 74 and the ring 75, so as to fine-tune the shooting of the detection probe 33, so as to perform fine shooting and detection of different parts of the inner wall of the fuel tank. When the deflection rod 72 deflects and tilts, it can also push the detection swab 77 at the end of the deflection head 76 to wipe the inner wall of the fuel tank. After the detection is completed, when the detection probe 33 is pulled out of the fuel tank, the cleanliness of the inner wall of the fuel tank can be further understood by observing the stains on the detection swab 77.

[0045] Furthermore, in order to facilitate the rapid replacement of the detection swab 77 to detect different engineering machinery oil tanks, such as Fig. 9 and Fig.10 As shown, this implementation provides the following technical solutions:

[0046] A mounting groove is provided at the end of the deflection rod 72, and a deflection head 76 is movably arranged between the inner walls of the mounting groove. A thin rubber rod 721 is fixedly connected to the inner wall of the mounting groove. A piston cavity 761 is provided on the deflection head 76 corresponding to the thin rubber rod 721. The end of the thin rubber rod 721 extends into the interior of the piston cavity 761, and a piston head 722 is fixedly connected to the end of the thin rubber rod 721 in the piston cavity 761. The piston head 722 is movably engaged between the inner walls of the piston cavity 761. An elastic membrane 762 is fixedly connected between the inner walls at the bottom port of the piston cavity 761, and a fixed portion of the elastic membrane 762 is provided at the middle of the elastic membrane 762. A positioning rod 763 is fixedly connected, and the end of the positioning rod 763 extends to the outside of the bottom port of the piston chamber 761. The end of the positioning rod 763 is movably connected to two groups of movable connecting rods 764. The ends of the two groups of movable connecting rods 764 are respectively provided with limiting holes 765. L-shaped limiting rods 766 are respectively fixedly connected to the outer walls on both sides of the bottom port of the piston chamber 761. The ends of the two groups of movable connecting rods 764 are respectively movably clamped on the outer walls of the cross bars of the L-shaped limiting rods 766 on both sides of the bottom of the piston chamber 761 through the limiting holes 765. The movable connecting rods 764 are used to limit the detection swab 77.

[0047] A limiting groove 771 is provided in the middle of the upper end of the detection swab 77, and an annular flexible protrusion 772 is fixedly connected to the top of the detection swab 77 outside the limiting groove 771. An annular groove 767 is provided at the bottom of the deflection head 76 corresponding to the annular flexible protrusion 772. When the piston head 722 is set in contact with the elastic membrane 762, the detection swab 77 is set in contact with the bottom of the deflection head 76. At this time, the movable connecting rod 764 is located in the limiting groove 771, and one end of the movable connecting rod 764 close to the limiting hole 765 is set horizontally in contact with the inner wall of the limiting groove 771 port.

[0048] Specifically, the detection swab 77 is pushed to drive the deflection head 76 to deflect 90 degrees at the bottom of the deflection rod 72. During the deflection, the deflection head 76 uses the piston cavity 761 to elastically bend the thin rubber rod 721. After bending, the thin rubber rod 721 drives the piston head 722 to move away from the bottom port of the piston cavity 761 to create a negative pressure environment between the piston head 722 and the elastic membrane 762. The negative pressure pulls the elastic membrane 762 to deform concavely inside the piston cavity 761. The elastic membrane 762 pulls the positioning rod 763 to move into the piston cavity 761. The positioning rod 763 drives the movable connecting rod 764 to deflect and move on the outer wall of the cross bar of the L-shaped limiting rod 766 based on the limiting hole 765. When one end of the limiting hole 765 is away from the positioning rod 763 and fits into the cross bar of the L-shaped limiting rod 766, the movable connecting rod 764 is controlled to disengage from the limiting groove 771 at the top of the detection swab 77. At this time, the detection swab 77 can be removed and replaced. On the contrary, after the annular flexible protrusion 772 on the new detection swab 77 is pressurized and engaged in the annular groove 767 at the bottom of the deflection head 76, the detection swab 77 is rotated to push the deflection head 76 to restore the straight state with the deflection rod 72. After the movable connecting rod 764 is deflected to the horizontal again, it is restricted to the lower ends of the top plates on both sides of the limiting groove 771 at the top of the detection swab 77, thereby realizing the locking of the new detection swab 77, which is convenient and quick.
