Description

Technical Field

[0001] This invention belongs to the field of manufacturing thin oil sealed gas holders, and specifically relates to an automatic leveling device for a gas holder piston and its control method. Background Technology

[0002] Currently, in both domestic and international thin-oil sealed gas holders, the piston tilt often exceeds the standard during actual operation after leveling. This is mostly caused by asynchronous deformation of the gas holder and the piston, leading to blockage in parts of the piston. Severe piston tilt can damage the sealing mechanism, causing gas to leak into the air through the piston's oil groove. Because the piston assembly of thin-oil sealed gas holders is enormous, manual adjustment alone is insufficient for real-time adjustment of the piston tilt. Therefore, an automatic piston leveling device is needed to achieve real-time adjustment of the piston tilt. Summary of the Invention

[0003] To address the aforementioned problems, the present invention provides an automatic piston leveling device for a gas holder. The automatic piston leveling device is mounted on a piston guide wheel frame, which is positioned in four horizontal directions of the gas holder. The automatic piston leveling device includes a rubber packing clamping device cylinder and a rubber packing clamping device transmission arm, with the rubber packing clamping device cylinder and the rubber packing clamping device transmission arm fixedly connected.

[0004] A further preferred technical solution is: it also includes a piston level adjustment device drive shaft, which passes through the rubber packing clamping device drive arm.

[0005] A further preferred technical solution is as follows: it also includes a rubber packing clamping device, wherein the power transmission arm of the rubber packing clamping device is movably connected to the rubber packing clamping device via the transmission shaft of the piston horizontal adjustment device.

[0006] A further preferred technical solution is that the rubber packing clamping device contacts the inner wall of the rubber packing clamping device transmission arm.

[0007] A further preferred technical solution is: it also includes a rubber packing adjusting bolt, which passes through the rubber packing clamping device.

[0008] A further preferred technical solution is: the rubber adjusting bolt is threadedly connected to the rubber packing clamping device.

[0009] A further preferred technical solution is: it also includes rubber packing, which is assembled on a rubber packing clamping device, and the inner diameter of the rubber packing clamping device is adapted to the rubber packing.

[0010] A further preferred technical solution is as follows: the automatic leveling device for the gas holder piston also includes a signal receiver and a solenoid valve box, and the signal receiver and solenoid valve box are electrically connected to the cylinder of the rubber packing clamping device.

[0011] A further preferred technical solution is that each piston guide wheel frame is equipped with three piston automatic leveling devices.

[0012] Its further preferred technical solution includes the following steps:

[0013] When the gas holder online tilt detection system detects that the tilt exceeds the standard, the signal receiver of the piston level adjustment device on the side with the largest tilt and the solenoid valve box receive the action signal and send an action signal to the cylinder of the rubber packing clamping device.

[0014] When the cylinder of the rubber packing clamping device is activated, the displacement generated by the activation of the cylinder is transmitted to the rubber packing clamping device through the transmission arm and piston level adjustment device drive shaft, causing the rubber packing assembled inside the rubber packing clamping device to be squeezed onto the column.

[0015] The rubber packing contacts the column to increase friction, thus reducing the tilt angle of the gas holder;

[0016] When the gas holder online tilt detection system detects that the tilt is within acceptable limits, the signal receiver of the activated piston leveling device and the solenoid valve box receive the end-of-action signal.

[0017] When the cylinder of the rubber packing clamping device finishes its operation, the piston horizontal adjustment device drive shaft and the rubber packing clamping device retract, and the rubber packing separates from the column, no longer increasing friction.

[0018] The beneficial effects of this invention are as follows: To prevent jamming caused by asynchronous deformation of the gas holder and piston, the piston's operating mode must be improved to reduce jamming. Simultaneously, real-time adjustment of the piston tilt angle of the thin oil-sealed gas holder is required. This necessitates an automatic leveling device for the gas holder that adjusts in real-time based on the online tilt detection signal. The automatic leveling device is activated by a combination of the online tilt detection signal and the piston's upward or downward movement (determined by the gas holder position signal).

[0019] To address the requirement for real-time adjustment of the piston tilt angle in a thin-oil sealed gas holder, an automatic piston leveling device for gas holders has been invented and designed. This method includes an automatic piston leveling device and an automatic control system. This automatic piston leveling device for gas holders is not only convenient to construct and maintain, but also consumes little energy. It can also adjust the piston tilt angle in real time to prevent piston tilt from damaging the sealing mechanism and causing a large amount of gas leakage.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1

[0028] like Figure 1 As shown, an automatic piston leveling device for a gas holder includes a gas holder, with piston guide wheel frames installed in all four horizontal directions of the gas holder, and an automatic piston leveling device installed on the piston guide wheel frames. Figure 3 As shown, each piston guide wheel frame is equipped with three piston automatic leveling devices.

[0029] The piston automatic leveling device includes a rubber packing clamping device cylinder 1 and a rubber packing clamping device transmission arm 6, with the rubber packing clamping device cylinder 1 and the rubber packing clamping device transmission arm 6 fixedly connected.

[0030] like Figure 2 As shown, the rubber packing clamping device transmission arm 6 is also equipped with a piston level adjustment device transmission shaft 4, which passes through the rubber packing clamping device transmission arm 6.

[0031] The piston leveling device drive shaft 4 and the rubber packing clamping device drive arm 6 are set up so that the displacement generated by the movement of the rubber packing clamping device cylinder 1 can be transmitted to the rubber packing clamping device 5 through the rubber packing clamping device drive arm 6 and the piston leveling device drive shaft 4. The purpose of setting up the piston leveling device drive shaft 4 is to enable the piston automatic leveling device to better adapt to the deformed column 8 surface.

[0032] The rubber packing clamping device is equipped with a rubber packing clamping device 5 inside the power arm 6. The rubber packing clamping device 5 is connected to the power arm 6 of the rubber packing clamping device through the transmission shaft 4 of the piston horizontal adjustment device. It also includes a rubber packing adjusting bolt 2 that passes through the rubber packing clamping device 5.

[0033] The rubber packing 3 is assembled on the rubber packing clamping device 5, and the inner diameter of the rubber packing clamping device 5 is adapted to the rubber packing 3.

[0034] The automatic leveling device for the gas holder piston also includes a solenoid valve box and a signal receiver. The signal receiver and solenoid valve box 7 are electrically connected to the cylinder 1 of the rubber packing clamping device.

[0035] Each piston guide wheel is equipped with three piston automatic leveling devices to improve the speed of piston tilt adjustment. One piston automatic leveling device cannot achieve real-time adjustment, while more than three piston automatic leveling devices would increase the upgrade cost.

[0036] Example 2

[0037] When the piston of the thin oil sealed gas holder is in the rising phase, if the online tilt detection system of the gas holder detects that the tilt exceeds the standard, it will issue a command in conjunction with the piston rising signal, and the piston automatic leveling device as described in Example 1 will start to operate. The steps are as follows:

[0038] The signal receivers of the three piston leveling devices on the side with the greatest upward tilt and the solenoid valve box 7 receive the action signal;

[0039] Pressure is applied by the cylinder 1 of the rubber packing clamping device and the transmission shaft 4 of the piston leveling device to press the rubber packing clamping device 5 onto the column 8. The contact between the rubber packing 3 and the column 8 increases the friction of the piston on this side, and the piston on the other side is lifted upward by the piston's upward force.

[0040] When the gas holder online tilt detection system detects that the tilt is within acceptable limits, the signal receivers of the three activated piston leveling devices and the solenoid valve box 7 receive the end-of-action signal. The cylinder 1 of the rubber packing clamping device retracts, retracting the piston leveling device drive shaft 4 and the rubber packing clamping device 5. The rubber packing 3 disengages from the column 8 and no longer increases friction, allowing the piston to operate normally.

[0041] The excessive tilt of the gas holder piston after leveling is mostly caused by the asynchronous deformation of the gas holder and the piston, resulting in blockage in some positions. In order to achieve automatic leveling, an automatic piston leveling device is added to the piston guide wheel frame in the four horizontal directions of the gas holder. To improve the adjustment effect, three automatic piston leveling devices are set in each direction.

[0042] Example 3

[0043] When the piston of the thin oil sealed gas holder is descending, if the online tilt detection system detects that the tilt exceeds the standard, it will issue a command in conjunction with the piston descent signal. As described in Example 1, the automatic piston leveling device will then begin operation, with the following steps:

[0044] The signal receivers of the three piston leveling devices on the side with the greatest downward tilt and the solenoid valve box 7 receive the action signal;

[0045] The rubber packing clamping device 5 is pressed onto the column 8 by applying pressure through the cylinder 1 of the rubber packing clamping device and the transmission shaft 4 of the piston leveling device. The rubber packing 3 contacts the column 8 to increase the friction force of the piston on this side. The piston on the other side is pulled down by the piston's downward force.

[0046] When the gas holder online tilt detection system detects that the tilt is within acceptable limits, the signal receivers of the three activated piston leveling devices and the solenoid valve box 7 receive the end-of-action signal. The cylinder 1 of the rubber packing clamping device retracts, retracting the piston leveling device drive shaft 4 and the rubber packing clamping device 5. The rubber packing 3 disengages from the column 8 and no longer increases friction, allowing the piston to operate normally.

[0047] This automatic piston leveling device for gas holders is not only easy to install, simple to maintain, and consumes little energy, but it can also adjust the piston tilt in real time, effectively preventing piston tilt from damaging the sealing mechanism and causing a large amount of gas leakage.
