[0011] Beneficial effects

[0012] This invention provides a rod-type oil level sensor with a self-cleaning structure for solidified oil stains without disassembly. Compared with the prior art, it has the following advantages:

A follower frame is movably connected to the surface of the annular sleeve. A brush sleeve is fixedly connected to one side of the follower frame. One side of the vertical synchronization frame is fixedly connected to the surface of the float sensor. With the setting of the cleaning component, when the sensor is working, it drives the annular sleeve to move by itself, and at the same time drives the two cleaning mechanisms, the cleaning sleeve and the brush sleeve, to clean the moving rod. The cleaning sleeve can be quickly disassembled for maintenance, which is convenient for operators. It solves the problem that impurities are easily mixed in the oil tank, and the impurities mixed with solidified oil stains are very easy to adhere to the surface of the rod-type liquid level sensor, which directly affects the up and down movement of the float and affects the measurement accuracy.

A contact plate is fixedly connected to the bottom of the lifting rod, and the surface of the contact plate has friction textures. A positioning spring is fitted onto the surface of the lifting rod, and mounting bolts are fixedly connected to the surface of the contact plate. Through the installation assembly, the device can contact the bottom of the inner wall of the oil tank via the contact plate and be directly fixed to the oil tank via the mounting bolts, preventing the rod-type oil level sensor from shaking. Furthermore, the positioning spring effectively buffers minor natural vibrations in mountainous areas, ensuring the normal operation of the sensor. Attached Figure Description

[0022] Please see Figure 1-5 This utility model provides two technical solutions:

[0023] Example 1

[0024] A rod-type oil level sensor with a self-cleaning structure for solidified oil stains without disassembly includes a top mounting plate 1. A stabilizing plate 2 is fixedly connected to the bottom of the top mounting plate 1. A movable rod 3 is fixedly connected to the middle of the bottom of the stabilizing plate 2. A float sensor 4 is movably sleeved on the surface of the movable rod 3. A mounting assembly 5 is fixedly connected to the bottom of the movable rod 3. A cleaning assembly 6 is movably sleeved on the surface of the movable rod 3. The cleaning assembly 6 includes a vertical synchronization frame 61 fixedly connected to the top of the float sensor 4. An annular sleeve 62 is fixedly connected to one side of the vertical synchronization frame 61. A connecting threaded groove 63 is formed on the surface of one side of the annular sleeve 62. A synchronization post 64 is movably connected to one side of the annular sleeve 62. A screw rod 65 penetrates the surface of the synchronization post 64. A screw head 66 is fixedly connected to one end of the synchronous column 64. A cleaning sleeve 67 is fixedly connected to one side of the surface of the synchronous column 64. A follower frame 68 is movably connected to the surface of the annular sleeve 62. A brush sleeve 69 is fixedly connected to one side of the follower frame 68. One side of the vertical synchronous frame 61 is fixedly connected to the surface of the float sensor 4. With the setting of the cleaning component 6, when the sensor is working, it will drive the annular sleeve 62 to move by itself, and at the same time drive the two cleaning mechanisms, the cleaning sleeve 67 and the brush sleeve 69, to clean the moving rod 3. The cleaning sleeve 67 can be quickly disassembled and maintained, which is convenient for operators. It solves the problem that impurities are easily mixed in the oil tank, and the impurities mixed with solidified oil stains are easy to adhere to the surface of the rod-type liquid level sensor, which directly affects the up and down movement of the float and affects the measurement accuracy.

[0025] Example 2

[0026] The main difference from Example 1 is:

[0027] A rod-type oil level sensor with a self-cleaning structure for solidified oil stains without disassembly includes a mounting assembly 5 comprising a movable cylinder 51 fixedly connected to the bottom end of a movable rod 3, the surface of which is provided with reinforcing ribs. A baffle 52 is slidably connected to the inner wall of the movable cylinder 51, the surface of which is polished smooth. A lifting rod 53 is fixedly connected to the center of the bottom of the baffle 52, the surface of which is provided with reinforcing ribs. A contact plate 54 is fixedly connected to the bottom end of the lifting rod 53, the surface of which is provided with friction texture. A positioning spring 55 is fitted onto the surface of the lifting rod 53, and mounting bolts 56 are fixedly connected to the surface of the contact plate 54. Through the mounting assembly 5, the device can directly contact the bottom of the inner wall of the oil tank via the contact plate 54 and be fixed to the oil tank via the mounting bolts 56, preventing the rod-type oil level sensor from shaking. Furthermore, the positioning spring 55 effectively buffers minor natural vibrations in mountainous areas, ensuring the normal operation of the sensor.

[0028] The model of the float sensor 4 is DH150-7. The deformation of the positioning spring 55 is extremely small, less than the self-vibration of the float sensor 4 caused by the fluctuation of the liquid. The cleaning sleeve 67 and the brush sleeve 69 are each composed of two semi-circular rings.

[0029] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0030] During operation, the positioning spring 55 at the bottom of the movable cylinder 51 pushes the contact plate 54 to move, and at the same time drives the baffle 52 to slide in the movable cylinder 51, fixing the contact plate 54 to the bottom of the inner wall of the oil tank. Rotate the mounting bolt 56 to fix it as a whole. When the float sensor 4 changes normally, the float sensor 4 drives the vertical synchronization frame 61 and the annular sleeve 62 to move up and down. The annular sleeve 62 drives the synchronization column 64 and the cleaning sleeve 67, and at the same time drives the follower frame 68 and the brush sleeve 69 to move. The cleaning sleeve 67 and the brush sleeve 69 clean the surface of the moving rod 3. When the oil tank is being maintained, if the cleaning sleeve 67 is extremely dirty, rotate the screw head 66 to separate the screw rod 65 from the connecting thread groove 63, and then separate the synchronization column 64 from the cleaning sleeve 67. After reinstallation, it continues to work normally.
