[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] This embodiment discloses a switch oil pool cleaning device, such as Figures 1 to 6 As shown, the invention aims to provide an efficient, convenient and environmentally friendly oil pool cleaning solution, which is suitable for the maintenance and cleaning of turnout oil pools. The composition and working principle of the device are described in detail as follows.

[0025] The turnout oil pool cleaning device mainly includes an oil pool 1, an oil pump 2, a refueling tank 3 and a waste oil tank 4. The oil pool 1 is used to collect oil, and the oil pump 2 is used as a driving device to circulate and transfer oil. The refueling tank 3 is responsible for storing new oil, and the waste oil tank 4 is used to collect old oil and waste oil discharged from the oil pool.

[0026] The refueling tank 3 is provided with a first oil pipe 31 extending into the bottom thereof, the oil pool 1 is provided with a second oil pipe 11 extending into the bottom thereof, and a first three-way solenoid valve 5 is provided between the upper end of the first oil pipe 31, the upper end of the second oil pipe 11 and the oil inlet of the oil pump 2. The oil pool 1 is also provided with a third oil pipe 12 extending therein, the waste oil tank 4 is provided with a fourth oil pipe 41 extending therein, and a second three-way solenoid valve 6 is provided between the upper end of the third oil pipe 12, the upper end of the fourth oil pipe 41 and the oil outlet of the oil pump 2.

[0027] In order to ensure the accuracy of operation, a refueling port 33 is provided at the top of the refueling tank 3, through which the user can conveniently add cleaning oil or new oil, and the refueling port is equipped with a detachable sealing cover 34 to ensure that the oil is not easy to leak. Preferably, the sealing cover 34 is connected to the refueling port 33 by threading, which is simple and convenient for the user to operate.

[0028] In addition, an oil drain pipe 43 is provided at the bottom of the waste oil tank 4, and an oil drain valve 44 is installed on the oil drain pipe 43 so that the old oil can be discharged after cleaning is completed to ensure a clean working environment.

[0029] The lower end of the third oil pipe 12 is equipped with a rotating spray head 121. During the oil pool cleaning process, the spray head can spray oil to clean the inner wall of the oil pool 1 in all directions, thereby improving the cleaning efficiency.

[0030] In order to prevent impurities in the oil from affecting subsequent operations, a detachable filter assembly 7 is also provided on the third oil pipe 12. Usually, the filter assembly 7 is composed of a shell 71 formed by butting two halves and a fixing member 72 for fixing the shell 71. The fixing member 72 is preferably a clamp. A replaceable filter element 73 is installed in the shell 71 to filter impurities in the oil. The filter element 73 usually adopts a filtering structure such as filter cotton. The filter element 73 can be detached and replaced, which is convenient for subsequent maintenance and cleaning.

[0031] Furthermore, the refueling tank 3 is provided with a first scale 32, and the waste oil tank 4 is provided with a second scale 42, so as to facilitate intuitive counting and control of the amount of refueling.

[0032] The specific cleaning process is divided into the following steps:

[0033] S1) Draining old oil: First, the second oil pipe 11 is connected to the oil inlet of the oil pump 2 through the first three-way solenoid valve 5, and at the same time, the second three-way solenoid valve 6 is connected to the oil outlet of the oil pump 2 and the fourth oil pipe 41. Then, the oil pump 2 is started to extract the old oil in the oil pool 1 into the waste oil tank 4. After the extraction is completed, the reading of the old oil in the waste oil tank 4 is recorded, and finally the drain valve 44 is opened to drain the old oil.

[0034] S2) Refueling: After the old oil is discharged from the oil pool, the sealing cover 34 is opened, and the cleaning oil with the same volume as the old oil is added to the refueling tank 3, and then the sealing cover 34 is re-covered. After that, the first oil pipe 31 is connected to the oil inlet of the oil pump 2 through the first three-way solenoid valve 5, and the second three-way solenoid valve 6 is connected to the oil outlet of the oil pump 2 and the third oil pipe 12. After the oil pump 2 is started, the cleaning oil is pumped from the refueling tank 3 into the oil pool 1.

[0035] S3) Circulation cleaning: After refueling is completed, the state of the solenoid valve is readjusted, the first three-way solenoid valve 5 conducts the second oil pipe 11 and the oil inlet of the oil pump 2, and the second three-way solenoid valve 6 connects the oil outlet of the oil pump 2 and the third oil pipe 12. After the oil pump 2 is started, the cleaning oil circulates between the oil pool 1, the second oil pipe 11, the oil pump 2 and the third oil pipe 12, and is effectively cleaned through the filter assembly 7 and the rotating nozzle 121 to ensure that the inner wall of the oil pool is thoroughly cleaned.

[0036] S4) Draining waste oil: After cleaning is completed, step S1 is performed again to drain the waste oil in the oil pool 1 to ensure that the cleaning work is thorough.

[0037] S5) Adding new oil: Finally, repeat step S2 to add new oil into the oil pool 1 to ensure the normal operation of the switch oil pool.

[0038] Through the above process, the turnout oil pool cleaning device can achieve efficient and convenient cleaning and maintenance, ensure the good working condition of the oil pool, and provide a strong guarantee for the normal operation of the turnout.
