Description

Technical Field

[0001] The utility model relates to the technical field of gear boxes, in particular to an intelligent management device for oil level in a gear box. Background Art

[0002] Lubricating oil is usually required in the gearbox or transmission of outboard motors, automobiles and some mechanical equipment to lubricate gears, bearings and other parts. At present, lubricating oil is usually added in advance, and when the lubricating oil level drops to a certain level, the lubricating oil is replenished or added. However, since the user may forget to add lubricating oil, the gears work in dry and unlubricated conditions, causing damage.

[0003] In order to solve the above problem, outboard motors, automobiles and some mechanical equipment are usually equipped with an oil dipstick. After opening the end cover, the oil dipstick is inserted and the liquid level of the lubricating oil in the gearbox is judged by the length of the wetting mark on the oil dipstick. The operation is rather troublesome. Utility Model Content

[0015] 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. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0016] See also Figure 1 , an intelligent management device for oil level in a gearbox, comprising a gearbox 1 and a central processing unit 2, wherein lubricating oil is filled in the gearbox 1, a first liquid level sensor 3 is installed on the inner wall of the gearbox 1 for detecting the liquid level of the lubricating oil in the gearbox 1, a tank body 4 is connected to the top of the gearbox 1 for filling the gearbox 1 with lubricating oil, a second liquid level sensor 5 is installed on the inner wall of the tank body 4 for detecting the liquid level of the lubricating oil in the tank body 4, and a solenoid valve 6 is installed at the outlet of the tank body 4; the central processing unit 2 is electrically connected to the first liquid level sensor 3 and the second liquid level sensor 5 respectively on one hand, and is electrically connected to the solenoid valve 6 on the other hand, and is electrically connected to an alarm 7 on the other hand, for outputting an alarm signal when the liquid level of the lubricating oil in the tank body 4 is lower than the position of the second liquid level sensor 5.

[0017] In the present invention, a gear 8 is installed inside the gear box 1, and the gear 8 is immersed in the lubricating oil in the gear box 1 to play a role of lubrication.

[0018] In the present invention, the first liquid level sensor 3 is located on the upper side of the gear 8, and is used as a setting liquid level so that the gear 5 can be immersed in the lubricating oil.

[0019] In the present invention, the second liquid level sensor 5 is located at the bottom of the tank body 4 , which is used as a set liquid level to ensure that the tank body 4 can store enough lubricating oil.

[0020] In the present invention, the alarm device 7 adopts an alarm lamp and a buzzer, so as to send out an audible and visual alarm signal.

[0021] In the utility model, an oil drain port 8 is provided at the bottom of the gear box 1, so as to discharge the dirty lubricating oil.

[0022] The utility model is further described below in conjunction with the accompanying drawings:

[0023] During use, when the liquid level of the lubricating oil in the gear box 1 is lower than the set liquid level, that is, lower than the position of the first liquid level sensor 3, it is sensed by the first liquid level sensor 3 and sends a signal to the central processing unit 2. The central processing unit 2 then sends a control signal to the solenoid valve 6. The solenoid valve 6 opens, and the lubricating oil stored in the tank 4 is filled into the gear box 1, so that the gear 8 is immersed in the lubricating oil in the gear box 1 again, avoiding further losses and effectively improving the service life of the gear box 1.

[0024] The lubricating oil level in the gearbox 1 gradually increases. When the lubricating oil level rises to the position of the first level sensor 3, it is sensed by the first level sensor 3 and sends a signal to the central processor 2. The central processor 2 then sends a control signal to the solenoid valve 6, and the solenoid valve 6 is closed, stopping the filling of lubricating oil into the gearbox 1.

[0025] When the liquid level of the lubricating oil in the tank body 4 is lower than the set liquid level, that is, lower than the position of the second liquid level sensor 5, it is sensed by the second liquid level sensor 5 and sends a signal to the central processor 2. The central processor 2 then sends a control signal to the alarm 7. The alarm 7 (alarm light and buzzer) outputs an audible and visual alarm signal, thereby informing the user to add lubricating oil in time.

[0026] After receiving the alarm signal, the user adds lubricating oil into the tank body 4 .

[0027] The lubricating oil level in the tank body 4 gradually rises. When the lubricating oil level rises to the position of the second level sensor 5, it is sensed by the second level sensor 5 and sends a signal to the central processor 2. The central processor 2 then controls the alarm 7 to stop outputting the sound and light alarm signal, that is, the alarm 7 is turned off.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
