[0027] The present utility model will be further described below in conjunction with the accompanying drawings.

[0028] As Figure 1 and Figure 2As shown in the figure, a lubricating oil detection device according to an embodiment of the present utility model includes a tank body 1. A filter plate 2 is provided inside the tank body 1. Above the filter plate 2 is a temporary storage area 11, and below the filter plate 2 is a detection area 12. A fan assembly 3 and an oil inlet assembly 4 are provided at the top of the tank body 1. The oil inlet assembly 4 is communicated with the temporary storage area 11. The fan assembly 3 can cool the lubricating oil entering the temporary storage area 11. A temperature sensor 51, a heating element 52 and a stirring assembly 6 are provided at the bottom of the tank body 1. The heating element 52 heats the lubricating oil in the detection area 12, and the stirring assembly 6 stirs the lubricating oil in the detection area 12.

[0029] After the lubricating oil enters the interior of the tank body 1 through the oil inlet assembly 4, it will first enter the temporary storage area 11. After being filtered by the filter plate 2 to remove impurities, it then flows into the detection area 12. The temperature sensor 51 provided at the bottom of the tank body 1 detects the temperature of the lubricating oil flowing into the detection area 12. If the temperature is too high, the fan assembly 3 provided at the top of the tank body 1 cools the lubricating oil flowing into the tank body 1. If the temperature is too low, the heating element 52 provided at the bottom of the tank body 1 heats the lubricating oil in the detection area 12 to avoid solidification, thereby realizing the adjustment of the temperature of the lubricating oil and making the temperature of the lubricating oil in a suitable range for detection. The stirring assembly 6 makes the components of the lubricating oil in the detection area 12 more uniform, improving the accuracy of detection.

[0030] In this embodiment, the heating element 52 is in a ring shape and has a large contact area with the lubricating oil in the detection area 12. After being energized, it can generate heat to heat the lubricating oil.

[0031] As Figure 3 shown, the oil inlet assembly 4 includes an oil inlet pipe 41, a suction oil pump 42 and a connecting pipe 43. The suction oil pump 42 pumps the lubricating oil into the oil inlet pipe 41 through the connecting pipe 43 and flows into the temporary storage area 11.

[0032] As Figure 2 and Figure 4 shown, the fan assembly 3 includes a mounting cylinder 31, a mounting frame 32, a dust-proof cover 33, fan blades 34 and a filter screen 35. The mounting cylinder 31 is provided at the top of the tank body 1. The mounting frame 32 is provided inside the mounting cylinder 31. The dust-proof cover 33 is provided at the top of the mounting frame 32 and is spaced from the mounting cylinder 31. The fan blades 34 are provided on the mounting frame 32. The filter screen 35 is provided at the bottom of the mounting cylinder 31. The dust-proof cover 33 can effectively prevent foreign matters such as external dust from directly falling into the interior of the mounting cylinder 31. The filter screen 35 intercepts the foreign matters entering the interior of the mounting cylinder 31 to prevent them from falling into the interior of the temporary storage area 11. The airflow generated after the fan blades 34 rotate can pass through the filter screen 35 and cool the lubricating oil inside the temporary storage area 11, achieving the effect of cooling the lubricating oil. The power mechanism of the fan blades 34 is not shown in the figure, and the fan blades 34 are electrically driven.

[0033] Furthermore, the mounting frame 32 includes a column 321 and a plurality of cross bars 322, the two ends of the cross bars 322 are respectively connected to the surface of the column 321 and the inner wall of the mounting tube 31, and the fan blades 34 are arranged on the column 321. The plurality of cross bars 322 can stably fix the column 321 inside the mounting tube 31, so that the dust cover 33, the fan blades 34 and the filter 35 arranged on the column 321 can remain stable.

[0034] like Figure 2 As shown, the dust cover 33 includes a top cover 331 and a side wall 332. The inner diameter of the side wall 332 is larger than the outer diameter of the mounting tube 31, and an annular air inlet 100 is formed between the side wall 332 and the mounting tube 31. The dust cover 33 covers the mounting tube 31 as a whole, and the air flow path is tortuous, which can well prevent foreign objects from entering the interior of the mounting tube 31.

[0035] like Figure 2 As shown, a liquid level sensor 53 is provided on the side of the filter plate 2 away from the temporary storage area 11. When the oil level in the detection area 12 contacts the liquid level sensor 53, the liquid level sensor 53 will send a corresponding signal, and the oil pump 42 will temporarily stop working to prevent the liquid level in the detection area 12 from being too high.

[0036] A detection member 54 is also provided at the bottom of the tank body 1, and the detection member 54 is selected according to the items to be detected. For example, when the water content of the lubricating oil needs to be detected, the detection member 54 selects a sensor for measuring the water content.

[0037] like Figure 5 and Figure 6 As shown, the stirring assembly 6 includes a stirring blade 61, a connecting rod 62 and a motor 63. The connecting rod 62 runs through the bottom of the tank body 1. The stirring blade 61 is arranged on the connecting rod 62 and is located inside the detection area 12. The motor 63 is arranged outside the tank body 1, and the output end of the motor 63 is connected to the connecting rod 62. The motor 63 drives the stirring blade 61 to rotate, so that the lubricating oil inside the detection area 12 is fully stirred. Since the motor 63 is arranged outside the tank body 1, it will not be affected by the lubricating oil inside the detection area 12.

[0038] Furthermore, the stirring assembly 6 also includes a fixing seat 64, which is arranged in the detection area 12 and fixed to the bottom of the tank body 1, and the fixing seat 64 is sleeved on the connecting rod 62. The fixing seat 64 can play a sealing effect on one hand to prevent the lubricating oil inside the tank body 1 from leaking, and on the other hand, it also supports and stabilizes the connecting rod 62, so that the connecting rod 62 is not easy to bend and deform.

[0039] like Figure 2 and Figure 7As shown, a base 7 is also provided below the tank body 1. The base 7 includes a support ring 71, support rods 72, and a bottom plate 73. The two ends of the support rods 72 are respectively connected to the support ring 71 and the bottom plate 73, and the support ring 71 supports the bottom of the tank body 1. The support ring 71 is annular, surrounds the bottom of the tank body 1, has a large contact area with the tank body 1, and also supports the side surface of the tank body 1, so that the tank body 1 can be kept stable on the base 7. The support rods 72 provide a certain space between the bottom of the tank body 1 and the bottom plate 73, facilitating the installation of components.

[0040] Furthermore, a bracket 74 is provided on the bottom plate 73, and the motor 63 is arranged in the bracket 74. The bracket 74 can support the motor 63 and keep the motor 63 stable, so that the motor 63 will not have obvious displacement even during operation.

[0041] As Figure 2 and Figure 8 shown, an oil drain assembly 8 is provided at the bottom of the tank body 1. The oil drain assembly 8 includes an oil drain pipe 81 and an oil drain valve 82 provided on the oil drain pipe 81. Through the oil drain assembly 8, the lubricating oil can be discharged from the inside of the tank body 1 for the next lubricating oil detection.

[0042] Although the present utility model has been described with reference to the preferred embodiments, various improvements can be made to it and its components can be replaced with equivalents without departing from the scope of the present utility model. In particular, as long as there is no structural conflict, the technical features mentioned in each embodiment can be combined in any way. The present utility model is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
