Abstract
Description
Technical Field

[0002] The diesel engine relies on lubricating oil to form an oil film on the surface of its transmission parts to lubricate its various parts. If the lubricating oil is insufficient or of poor quality, the engine will wear out, resulting in a reduction in service life. In severe cases, the engine transmission unit may even be greatly damaged. During the use of current diesel engines, especially during long-term continuous operation, the lubricating oil will suffer certain losses due to high-temperature carbon deposition and evaporation, which will lead to a drop in the oil level. The lubricating oil cannot be normally or fully supplied to the transmission parts, causing damage to the diesel engine. Therefore, in view of the fact that the oil level of the lubricating oil is prone to drop during the long-term operation of the above-mentioned diesel engine, if it cannot be replenished in time, it will cause wear of the diesel engine transmission parts and equipment failure. A device for automatically replenishing lubricating oil can be designed to prevent the oil level in the oil tank from being too low. Utility Model Content

[0020] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.
[0021] like Figure 1-7 As shown, an automatic lubricating oil replenishing device for a diesel engine is provided, wherein the diesel engine comprises a diesel engine body 1 and a fuel tank 2 connected to the diesel engine body 1 via an oil delivery pipe 4, wherein the replenishing device comprises a storage assembly for storing lubricating oil arranged on the diesel engine body 1, wherein a lubricating oil port 3 for entering lubricating oil is provided at the bottom of the diesel engine body 1, an oil pump 7 for transporting lubricating oil is connected to the outer wall of the diesel engine body 1, wherein the storage assembly is provided with a feedback assembly, wherein the feedback assembly comprises a controller and a liquid level gauge 603 arranged at the lubricating oil port 3 and electrically connected to the controller, wherein the oil pump 7 inputs lubricating oil into the diesel engine body 1 via the lubricating oil port 3 under the control of the feedback assembly, so as to lubricate mechanical transmission components in the diesel engine body 1.
[0022] Working principle: The feedback component is used to monitor the oil level height of the lubricating oil transported to the diesel engine body 1 by the oil pump 7, and ensure that the lubricating oil level is not lower than the minimum level that can lubricate the mechanical transmission parts in the diesel engine body 1. In order to avoid a low lubricating oil level in the diesel engine body 1, the feedback component should be at a lower level, that is, the set level can replenish the lubricating oil to increase the level. When the lubricating oil level in the diesel engine body 1 is low: the oil pump 7 inputs the lubricating oil into the diesel engine body 1 through the lubricating oil port 3 under the control of the feedback component to increase the lubricating oil level. The level meter 603 is a submersible high-temperature resistant level transmitter. The level meter model is MIK-P260S, and the controller model is 80C51. The level of the lubricating oil in the diesel engine body 1 should be set by the controller with a set lower limit level. , which can be achieved by adapting to the actual size of the diesel engine or the minimum liquid level required by the vast majority of diesel engine lubricants on the market. It is preferred to set an upper limit on the liquid level. Since the liquid level gauge 603 usually does not penetrate the diesel engine body 1, it can be achieved by setting the maximum liquid level required by the diesel engine lubricant not to exceed the range of the liquid level gauge 603; when the oil level in the oil tank drops to the preset value of the liquid level gauge 603, the liquid level gauge 603 sends a signal to the controller, and the controller starts the oil pump 7 to extract the lubricating oil in the storage component and transport it to the diesel engine body 1, and replenish it to a suitable oil level height, and provide it to the mechanical transmission parts for lubrication. After the above steps, through the linkage between the storage component, the feedback component and the oil pump 7, when the oil level in the diesel engine body 1 is outside the set range, automatic replenishment of the lubricating oil can be achieved.

The oil extraction port 502 is connected to the oil inlet of the oil pump 7 through a hose. The gap formed by the separate structure between the fuel tank 2 and the diesel engine body 1 is used as the placement point of the lubricating oil storage component. The hard fuel tank and the diesel engine body are used as the protective structure of the lubricating oil storage component to prevent the storage component from being damaged by collision. The lubricating oil bin 501 is usually provided with an inlet for lubricating oil so that a hose can be connected to replenish the lubricating oil into the lubricating oil bin 501.

The fasteners are used to enhance the connection strength between the lubricating oil bin 501 and the oil pipeline 4 to prevent the storage assembly from detaching from the diesel engine due to vibration and other reasons when the diesel engine is working, thereby improving the operating stability of the device.
[0025] Preferably, the storage assembly is provided with a heat-conducting element 503 for conducting heat to the lubricating oil, the heat-conducting element 503 comprises a vertical heat-conducting copper tube arranged outside the anchor ring 8 and a spiral heat-conducting copper tube arranged in the lubricating oil bin 501, the spiral heat-conducting copper tube surrounds the cavity of the lubricating oil bin 501, one end of the vertical heat-conducting copper tube is inserted into the diesel engine body 1, and the other end is connected to the spiral heat-conducting copper tube, the vertical heat-conducting copper tube and the spiral heat-conducting copper tube constitute a good heat-conducting system, which transfers the heat in the mechanical transmission bin to the lubricating oil, so that the pumped supplementary oil is at a suitable temperature, avoiding the diesel engine from having a reduced operating efficiency due to the oil temperature being too low, the vertical heat-conducting copper tube is plugged into the mechanical transmission bin through the opening at the upper end of the diesel engine body 1 and conducts the heat of the mechanical transmission to the spiral heat-conducting copper tube, and preheats the lubricating oil in the lubricating oil storage assembly by means of the high temperature generated when the mechanical transmission bin of the diesel engine is running, avoiding the oil supplemented into the oil bin from being in a low temperature state, thereby affecting the transmission efficiency of the diesel engine.
[0026] Preferably, the outer side of the vertical heat-conducting copper tube is provided with a protective sleeve 10 fixed on the diesel engine body 1, and the protective sleeve 10 is used to store the lubricating oil in the assembly for heat preservation. The inner wall of the protective sleeve 10 is preferably made of a material with good thermal insulation properties, which protects and insulates the vertical heat-conducting copper tube and reduces heat loss, such as glass wool with waterproof properties.
[0027] Preferably, the feedback component also includes a screw cap 601 and a fuel injector 602 which are detachably connected to the lubricating oil port 3. The fuel injector 602 and the liquid level gauge 603 are inserted through the screw cap 601 into the diesel engine body 1.
