Technical Field
[0001] The utility model relates to the technical field of movement, in particular to an oil-immersed ground column movement. Background Art
[0002] The oil-immersed ground column movement is a special lifting column movement, which is characterized by directly immersing the drive components and oil circuit blocks in liquid oil. This design can improve the sealing performance of the movement structure, while also avoiding the trouble of separately setting up the oil cylinder and the drive components and then connecting them, thereby simplifying the structure of the entire system.
[0003] When the oil-immersed floor-column movement is actually used, the lubricating oil plays a vital role in the movement, which can reduce friction, reduce heat generation, and remove heat through circulation to ensure that the temperature of the movement is within a reasonable range. Therefore, it is necessary to regularly monitor the internal oil. At the same time, the oil level of the lubricating oil should also be checked regularly to ensure that it is within the appropriate range. If the oil level is too low, it may lead to insufficient lubrication and affect the normal operation of the movement; if the oil level is too high, it may increase the burden on the movement and accelerate wear.
[0004] However, the existing oil-immersed floor column movement lacks an automatic alarm structure for abnormal oil level, which results in the staff being unable to promptly detect the problem of low or high oil level, affecting the normal use of the oil-immersed floor column movement.
[0005] To this end, the present application provides an oil-immersed ground column movement to solve the above-mentioned technical problems. Utility Model Content
[0006] The purpose of this application is to provide an oil-immersed ground column movement. When the oil level in the oil-immersed ground column body is too low or too high, it will drive the conductive floating plate to electrically connect the first conductive plate and the second conductive plate, so that the buzzer is energized to sound an alarm, which is conducive to timely reminding the staff to perform maintenance. The use effect is good and it is safe and reliable.

[0008] An insulating tube is installed on the monitoring tube, and a power box and a buzzer are respectively installed on both sides of the outer edge surface of the insulating tube, and the upper and lower ends of one side of the interior of the insulating tube are fixed with a first conductive sheet electrically connected to the power box, and the upper and lower ends of the other side of the interior of the insulating tube are fixed with a second conductive sheet electrically connected to the buzzer, and a conductive floating plate floating on the oil is provided in the monitoring tube, and the conductive floating plate is located in the middle position between the top and bottom ends of the interior of the insulating tube.
[0009] Preferably, the conductive floating plate does not contact the first conductive sheet and the second conductive sheet when the oil level in the oil-immersed ground column body is normal.
[0010] Preferably, the conductive floating plate comprises a foam floating plate, a conductive copper sheet is fixed to the upper end surface of the foam floating plate, and the conductive copper sheet is electrically connected and matched with the first conductive sheet and the second conductive sheet.
[0011] Preferably, a through hole is formed in the middle of the foam floating plate and the conductive copper sheet, and a sampling dropper is inserted into the top of the monitoring tube, and the sampling dropper passes through the through hole.
[0012] Preferably, the top of the monitoring tube is provided with an opening for vertically inserting the sampling dropper, and the top of the sampling dropper is sealed and plugged into the top opening of the monitoring tube.

DETAILED DESCRIPTION
[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] Example: Reference Figure 1 and Figure 2 The oil-immersed ground column movement shown in the figure comprises an oil-immersed ground column body 1 with oil inside, an organic core shaft 2 is arranged on the upper end face of the oil-immersed ground column body 1, a vertical monitoring tube 3 is arranged on the side of the end of the oil-immersed ground column body 1, and connecting tubes 301 connected to the inside of the oil-immersed ground column body 1 are fixed at the upper and lower ends of the monitoring tube 3, forming a communicating vessel for the oil in the oil-immersed ground column body 1 to enter.
[0026] like Figure 3As shown, an insulating tube 4 is installed on the monitoring tube 3, and a power box 5 and a buzzer 6 are installed on both sides of the outer edge of the insulating tube 4, respectively. The upper and lower ends of one side of the inner side of the insulating tube 4 are fixed with a first conductive sheet 7 electrically connected to the power box 5, and the upper and lower ends of the other side of the inner side of the insulating tube 4 are fixed with a second conductive sheet 8 electrically connected to the buzzer 6, and a conductive floating plate 9 floating on the oil is provided in the monitoring tube 3, as shown in FIG. Figure 4 As shown, the conductive floating plate 9 includes a foam floating plate 901 , and a conductive copper sheet 902 is fixed to the upper end surface of the foam floating plate 901 . The conductive copper sheet 902 is electrically connected and matched with the first conductive sheet 7 and the second conductive sheet 8 .
[0027] At the same time, the conductive floating plate 9 is located in the middle position between the top end and the bottom end of the insulating tube 4, wherein the conductive floating plate 9 does not contact the first conductive plate 7 and the second conductive plate 8 when the oil level in the oil-immersed ground column body 1 is normal, so that the circuit between the buzzer 6 and the power box 5 is broken.
[0028] When the oil level in the oil-immersed ground column body 1 is too low or too high, the conductive floating plate 9 will be electrically connected to the first conductive sheet 7 and the second conductive sheet 8, so that the power box 5 can supply power to the buzzer 6, so that the buzzer 6 can be powered on and sound an alarm to remind the staff to carry out timely inspection and maintenance.
[0029] In addition, in this embodiment, the foam floating plate 901 and the conductive copper sheet 902 are provided with a through hole 903 in the middle, and a sampling dropper 10 is inserted into the top of the monitoring tube 3, and the sampling dropper 10 passes through the through hole 903.

Therefore, when the oil level of the lubricating oil in the oil-immersed ground column body 1 is too low or too high, it will drive the conductive floating plate 9 to be electrically connected with the first conductive sheet 7 and the second conductive sheet 8 on both sides of the bottom of the insulating tube 4, or drive the conductive floating plate 9 to be electrically connected with the first conductive sheet 7 and the second conductive sheet 8 on both sides of the top of the insulating tube 4, so that the power box 5 will supply power to the buzzer 6, so that the buzzer 6 is powered on and an alarm is issued, so as to promptly remind the staff to perform maintenance, with good use effect, safety and reliability.
[0032] In addition, due to the sampling dropper 10 set on the top of the monitoring tube 3, the staff can easily extract the oil in the oil-immersed ground column body 1 through the sampling dropper 10 during maintenance, so as to facilitate the staff to judge whether the oil is deteriorated according to the color and smell of the oil, so as to avoid the deterioration of the lubricating oil and affect the normal operation of the movement, which is beneficial to improve the staff's inspection and maintenance efficiency of the movement oil and is easy to use.
