Description

Technical Field

[0001] The utility model relates to the technical field of generators, in particular to an oil level control structure for a diesel engine. Background Art

[0002] Existing diesel generators mostly require manual oil replenishment. However, when the engine starts, the gears and other internal mechanisms draw some oil into the gearbox, causing the oil level to decrease and become low. When the engine stops, the oil drawn into the gearbox gradually flows back into the oil tank. Therefore, manual oil replenishment makes it difficult to determine the appropriate oil level and ensure timely replenishment, leading to the risk of wear and tear on the engine. Furthermore, manual replenishment is prone to oversight, which can damage the engine. Utility Model Content

[0003] The utility model discloses an oil level control structure for a diesel engine, aiming to improve the problem that the oil level of the existing diesel engine cannot be controlled in real time.

[0004] The utility model adopts the following scheme:

[0006] As a further improvement, the oil storage tank is further provided with an oil inlet, and the oil inlet and the oil outlet are respectively provided with a first switch valve and a second switch valve.

[0007] As a further improvement, the liquid level retainer is provided with an inspection channel for connecting to a manual pump, so that the oil in the oil tank can be discharged under the action of the manual pump.

[0008] As a further improvement, the manual pump includes a handle, an inlet and an outlet. The inlet is used to connect to the maintenance channel and is provided with a third switch valve. By pressing the handle, the engine oil flows into the inlet and flows out from the outlet.

[0009] As a further improvement, the diesel engine, the liquid level retainer, the oil storage tank and the manual pump are all fixedly connected to the base.

[0010] As a further improvement, the oil inlet channel and the oil outlet, the oil outlet channel and the oil tank, and the maintenance channel and the manual pump are all connected by hoses.

[0011] As a further improvement, the liquid level switch includes a float and a valve. The float is arranged in the liquid level retainer and rises and falls with the liquid level in the liquid level retainer to link the valve to control the opening and closing of the oil inlet channel.

[0012] By adopting the above technical solution, the utility model can achieve the following technical effects:

[0013] 1. This application maintains the liquid level in the liquid level retainer consistent with the liquid level in the oil tank, so that when the liquid level in the oil tank drops to a set threshold, the oil inlet channel can be opened to achieve real-time replenishment of oil, avoiding the problem of wear of parts in the diesel engine due to insufficient oil, thereby ensuring the life of the diesel engine.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents the selected embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Example

[0028] Combine Figures 1 to 6 This embodiment provides an oil level control structure for a diesel engine, including an oil storage tank 1 and a liquid level retainer 2, wherein an oil outlet 11 is provided at the bottom of the oil storage tank 1, and the liquid level retainer 2 has an oil inlet channel 21, an oil outlet channel 22 and a liquid level switch, the oil inlet channel 21 is used to connect with the oil outlet 11, and the position of the oil outlet 11 is not lower than the position of the oil inlet channel 21, the oil outlet channel 22 is used to communicate with the bottom of the oil tank 31, and make the liquid level in the liquid level retainer 2 consistent with the liquid level in the oil tank 31, the liquid level switch is used to control the opening and closing of the oil inlet channel 21, and is configured to open the oil inlet channel 21 when the liquid level in the oil tank 31 is lower than a set threshold.

[0029] Exemplarily, the oil storage tank 1 is provided with an oil inlet 12 and an oil outlet 11, and is provided with a first on-off valve 121 and a second on-off valve 111, respectively. The opening and closing of the oil inlet 12 and the oil outlet 11 are controlled by the first on-off valve 121 and the second on-off valve 111, respectively. Both the first on-off valve 121 and the second on-off valve 111 are mechanical valves that are manually opened and closed. The second on-off valve 111, located on the oil outlet 11, is in a normally open state. The oil outlet 11 is connected to the oil inlet channel 21, and the opening and closing of the oil inlet channel 21 is controlled by a liquid level switch. When the liquid level in the oil tank 31 falls below a set threshold, the oil inlet channel 21 opens, and the oil in the oil storage tank 1 can flow from the oil outlet 11 to the oil inlet channel 21 under the action of gravity. When the liquid level in the oil tank 31 reaches the set threshold, the oil inlet channel 21 closes, thereby achieving automatic oil replenishment. The oil outlet channel 22 is connected to the bottom of the oil tank 31, and the coupling principle is used to make the liquid level in the level retainer 2 consistent with the liquid level in the oil tank 31. The threshold value of the liquid level in the oil tank 31 can be the minimum liquid level required after the diesel engine 3 is started.

[0030] It should be mentioned that, in this embodiment, by keeping the liquid level in the liquid level retainer 2 consistent with the liquid level in the oil tank 31, when the liquid level in the oil tank 31 drops to a set threshold, the oil inlet channel 21 can be opened to achieve real-time replenishment of oil, thereby avoiding the problem of wear of parts in the diesel engine 3 caused by insufficient oil, thereby ensuring the life of the diesel engine 3.

[0031] In a preferred embodiment, the liquid level retainer 2 is provided with an inspection channel 24 for connecting to a manual pump 4, so that the oil in the oil tank 31 can be discharged under the action of the manual pump 4. For example, the manual pump 4 includes a handle 41, an inlet 42, and an outlet 43. The inlet 42 is connected to the inspection channel 24 and is provided with a third on-off valve 421. By pressing the handle 41, the oil flows into the inlet 42 and out of the outlet 43. When the oil in the oil tank 31 needs to be inspected or replaced, the second on-off valve 111 on the oil outlet 11 can be closed first, and then the third on-off valve 421 can be opened. The handle 41 can be manually pressed to pump the oil out of the oil tank 31, thereby facilitating the inspection of the oil tank 31. In this structure, only one pipeline is required between the oil tank 31 and the liquid level retainer 2 to achieve oil replenishment and inspection, thereby simplifying the pipeline, facilitating the pipeline layout within the engine block, and making the structure more compact. It should be mentioned that the internal structure of the manual pump 4 and the structures of the switch valves are all prior art and will not be described in detail here.

[0032] Furthermore, the diesel engine 3, liquid level retainer 2, oil tank 1, and hand pump 4 are all fixedly connected to the base 5. The fixing method may be screws or other fasteners, or welding, without specific limitation. The oil inlet passage 21 and the oil outlet 11, the oil outlet passage 22 and the oil tank 31, and the inspection passage 24 and the hand pump 4 are all connected by hoses to facilitate the routing of the pipelines and facilitate installation.

[0033] Based on the above embodiments, in an optional embodiment of the present invention, the liquid level switch includes a float 231 and a valve 232. The float 231 is arranged in the liquid level retainer 2 and rises and falls with the liquid level in the liquid level retainer 2 to link the valve 232 to control the opening and closing of the oil inlet channel 21. For example, the float 231 is connected to the valve 232 via a spring 233, which is hinged to the inner wall of the liquid level retainer 2. When the liquid level in the oil tank 31 is above a set threshold, the float 231, under the action of buoyancy, drives the valve 232 to abut and seal against the oil inlet channel 21, at which time the oil inlet channel 21 is closed. When the liquid level in the oil tank 31 is below the set threshold, the position of the float 231 drops, causing the valve 232 to move away from the oil inlet channel 21, at which time the oil inlet channel 21 is opened, and the oil in the oil storage tank 1 can enter the oil inlet channel 21 under the action of gravity, and then enter the oil tank 31 from the oil outlet channel 22, thereby achieving automatic replenishment of the oil in the oil tank 31. The liquid level threshold can be controlled by adjusting the volume of the float 231 or the weight of the counterweight block connected to the spring 233. Not limited to this, in other embodiments, a liquid level retainer in the prior art, such as the Murphy liquid level meter LM500 / LM500-TF, etc., may also be used.

[0034] The above are only preferred implementations of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention fall within the protection scope of the present invention.
