Description

Technical Field

[0001] The utility model belongs to the technical field of oil tank oil supply, and more specifically, particularly relates to an automatic oil supply device for an oil tank. Background Art

[0002] Diesel generator sets use diesel to release energy to drive the engine to run and the generator to rotate to release electrical energy. Each generator set has a fuel tank for storing diesel. For small diesel generator sets, the fuel tank is relatively small and can only meet the power supply needs for a few hours. If you need to generate electricity for a long time, you must refuel the tank frequently to meet the needs.

[0003] In the prior art, the authorization publication number "CN110526196A" discloses an "automatic replenishment protection system and protection method for the chassis tank of a vehicle-mounted diesel generator set"; the automatic replenishment protection system includes a controller, a liquid level sensor and a first liquid level switch respectively arranged at the center of the chassis tank of the unit, a second liquid level switch, a third liquid level switch, a fourth liquid level switch and a fifth liquid level switch respectively arranged at the four corners of the chassis tank of the unit, and an electric oil pump connected between the external oil tank and the chassis tank of the unit through an oil pipeline for replenishing fuel to the chassis tank of the unit, and the liquid level sensor, the first liquid level switch, the second liquid level switch, the third liquid level switch, the fourth liquid level switch, the fifth liquid level switch and the electric oil pump are respectively connected to the controller through a signal control line. The present invention can effectively prevent fuel overflow caused by the tilt of the chassis tank of the unit during fuel replenishment, thereby improving the safety and reliability of the fuel replenishment system.

[0004] The above-mentioned "automatic replenishment protection system and protection method for chassis oil tank of vehicle-mounted diesel generator set" still has some disadvantages, for example: the oil storage tank of the existing diesel generator has a small amount of oil storage, and it needs to be manually refilled repeatedly during long-term operation, which increases the workload of the operator. At the same time, repeated refilling is easy to cause problems with the sealing of the oil tank, increasing the cost of subsequent maintenance. At the same time, if the oil used in the existing diesel generator has impurities and dust and has poor cleanliness, the diesel may increase the resistance and wear of the parts. At the same time, outdoor exposure will cause the diesel temperature to rise. The high oil temperature may cause the lubricating oil to oxidize and polymerize, and produce substances such as colloid and asphalt;

[0005] For this reason, an automatic oil supply device for a fuel tank is proposed here to solve the above-mentioned problems. Utility Model Content

[0006] In view of the deficiencies of the prior art, the utility model provides an automatic oil supply device for an oil tank to solve the problem in the above background technology that manual refilling is required during a long working process, which increases the workload of operators.

[0007] To achieve the above objectives, the utility model is implemented through the following technical solutions: an automatic oil supply device for an oil tank, including a diesel generator set, one side of the diesel generator set is fixedly connected to a diesel generator oil tank, one side of the diesel generator oil tank is provided with a liquid level sensor, one side of the liquid level sensor is provided with a transmission pipeline, one side of the transmission pipeline is provided with a diesel generator controller, an oil pipe is provided on the top of the liquid level sensor, one end of the oil pipe is provided with an external oil tank, one side of the external oil tank is provided with an electronic oil pump, a cleaning pipe is fixedly connected to the surface of the oil pipe, and a filter is fixedly connected to the inner side of the cleaning pipe.

[0009] Preferably, one end of the transmission disc is fixedly connected to a connecting rod, and one side of the connecting rod is fixedly connected to a transmission blade.

[0010] Preferably, a connecting plate is fixedly connected to the other side of the transmission disc, and a cleaning brush is fixedly connected to one side of the connecting plate.

[0011] Preferably: the bottom of the external oil tank is fixedly connected to a supporting base frame, one side of the external oil tank is fixedly connected to a liquid storage tank, the top of the liquid storage tank is fixedly connected to a filling port, the bottom of the liquid storage tank is fixedly connected to a controller body, one side of the controller body is provided with a temperature sensor, and the surface of the liquid storage tank is provided with a water pump body.

[0013] Compared with the prior art, the utility model provides an automatic oil supply device for an oil tank, which has the following beneficial effects:

[0014] 1) When the oil level in the fuel tank of the diesel generator is lower than the set oil level during operation, the liquid level sensor will send a signal, which will be transmitted to the diesel generator controller through the transmission pipeline. After receiving the signal, the diesel generator controller will drive the electronic oil pump on one side of the external fuel tank to replenish oil; when the set maximum oil level is reached, the liquid level sensor will send a signal to the diesel generator controller, and the diesel generator controller will send an instruction to the electronic oil pump to stop refueling, thereby realizing automatic refueling and reducing the workload of the operator. By using an external fuel tank to store more spare oil, the operator can be less likely to refill the oil repeatedly by hand, thereby improving the portability of refueling.

[0015] 2) When the automatic oil supply device of the fuel tank is working, when the liquid impacts the transmission blade, the rotating transmission disc drives the stirring blade to rotate, and the stirring blade can be used to stir the liquid on one side of the filter screen to improve the filtering effect of the liquid passing through the filter screen. At the same time, when the transmission disc rotates, it will drive the cleaning brush on one side of the connecting plate to contact along the surface of the filter screen, which can reduce the accumulation of impurity particles on the surface of the filter screen, resulting in a slow filtering efficiency, and improve the cleanliness of the diesel in the automatic supply process;

[0016] 3) When the oil temperature in the external oil tank exceeds the set temperature value during operation of the automatic oil supply device for the oil tank, the controller will drive the water pump body to work, and use the water pump body to drive the coolant in the liquid storage tank along the water pipe into the heat sink, and then flow back to the liquid storage tank through the other side of the heat sink to form a circulation. The coolant can cool the heat sink, thereby cooling the diesel in the external oil tank. BRIEF DESCRIPTION OF THE DRAWINGS
