Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 5 As shown, this utility model provides an oil replenishment device for a steam turbine oil tank, including a base plate 1. An adjustment mechanism is provided on the top of the base plate 1. The adjustment mechanism includes a telescopic component and a control component. The control component includes a fixing block 103 and a fixing block 2 104 fixedly installed on the top of the base plate 1. A round rod 4 is rotatably installed on the side of the fixing block 103 and the fixing block 2 104 that are close to each other. One end of the round rod 4 near the fixing block 103 extends out of the fixing block 103. A mounting groove 1031 is provided on the outer wall of the fixing block 103. A knob 5 is slidably installed on the outer wall of the round rod 4. A pull ring 502 is fixedly installed on one side of the knob 5. Rubber rings 6 are fixedly installed on the top and bottom of the round groove 102, respectively. Both rubber rings 6 abut against the oil replenishment pipe 3.

[0023] The user can adjust the depth of the oil replenishment pipe 3 by using the knob 5 in the control component. The sliding installation structure of the knob 5 and the round rod 4 allows the oil replenishment pipe 3 to move precisely in the vertical direction by pinching the pull ring 502 and rotating the knob 5, which simplifies the operation process and improves work efficiency. It is especially practical when the oil level in the tank needs to be adjusted frequently. The rotational installation of the round rod 4 between the first fixing block 103 and the second fixing block 104, as well as the sliding restriction of the knob 5 on the round rod 4, together ensure the stability and accuracy of the oil replenishment pipe 3 during the adjustment process. In addition, the setting of the rubber ring 6 further enhances the sealing and stability between the oil replenishment pipe 3 and the base plate 1, effectively preventing oil leakage and shaking of the oil replenishment pipe 3.

[0024] like Figures 1 to 2As shown, the telescopic assembly comprises a half ring block 101 fixedly installed at the top of the base plate 1, the top of the base plate 1 is provided with a circular groove 102, a supplementary oil pipe 3 is slidingly installed on the inner wall of the half ring block 101, the supplementary oil pipe 3 penetrates through the circular groove 102, a supplementary oil tank 2 is fixedly installed at the top of the supplementary oil pipe 3, a gear slot 301 is formed on the outer wall of the supplementary oil pipe 3, a gear 402 is fixedly sleeved on the outer wall of the circular rod 4, and the gear 402 is engaged with the gear slot 301.

[0025] Through the sliding installation of the supplementary oil pipe 3 on the inner wall of the half ring block 101 and the engagement of the gear 402 and the gear slot 301, the accurate and stable movement of the supplementary oil pipe 3 in the vertical direction is realized, so that the supplementary oil pipe 3 can be accurately adjusted to the required depth as required, and the shaking or instability phenomenon in the adjustment process is avoided.

[0026] As shown in the figure, Figure 4 The inner wall of the installation groove 1031 is fixedly installed with a magnetic sheet one 10311, and the side of the knob 5 close to the fixed block one 103 is fixedly installed with a magnetic sheet two 503, and the magnetic poles of the magnetic sheet two 503 and the magnetic sheet one 10311 are opposite.

[0027] By fixedly installing the magnetic sheet one 10311 on the inner wall of the installation groove 1031 and fixedly installing the magnetic sheet two 503 on the side of the knob 5 close to the fixed block one 103, and the magnetic poles are opposite, the knob 5 can be stably adsorbed in the installation groove 1031 after adjustment, and the loosening or falling off of the knob 5 due to accidental touch or vibration is effectively prevented.

[0028] As shown in the figure, Figures 3 to 4 A plurality of limiting grooves 401 are formed on the outer wall of the circular rod 4, the plurality of limiting grooves 401 are designed to be equidistantly circumferentially distributed, a plurality of limiting protrusions 501 are fixedly installed on the inner wall of the knob 5, the plurality of limiting protrusions 501 are matched with any limiting groove 401, and the plurality of limiting protrusions 501 are slidingly connected with the corresponding limiting groove 401.

[0029] Through the setting of the limiting groove 401 and the limiting protrusion 501, the knob 5 can slide on the circular rod 4 and can also drive the circular rod 4 to rotate through the rotation of the knob 5.

[0030] The working principle and use process of the utility model:

[0031] Confirm the need to adjust the depth of the oil supplement pipe 3, then pinch the pull ring 502 and pull outward, make the knob 5 from the installation groove 1031, release the fixed state of the knob 5, rotate the knob 5, because the limiting block 501 in the inner wall of the knob 5 and the limiting groove 401 on the outer wall of the round rod 4 are in sliding connection, the rotation of the knob 5 will drive the round rod 4 to rotate, the rotation of the round rod 4 further drives the gear 402 to rotate, through the meshing of the gear 402 and the tooth groove 301, the rotation of the gear 402 will be converted into the up-down movement of the oil supplement pipe 3 in the vertical direction, according to the need, continue to rotate the knob 5 to adjust the depth of the oil supplement pipe 3 into the inner wall of the oil tank.

[0032] After the adjustment is completed, the knob 5 is pushed in the opposite direction to make it slide into the installation groove 1031 again, the magnetic sheet one 10311 in the installation groove 1031 is attracted to the magnetic sheet two 503 on the side of the knob 5, so as to fix the knob 5 in the installation groove 1031, prevent the knob 5 from moving, so as to avoid the movement of the oil supplement pipe 3.
