TECHNICAL FIELD
[0001] The utility model relates to the technical field of explosion -proof diesel engine, especially relates to an explosion -proof diesel engine oil sump. BACKGROUND
[0002] The oil sump of diesel engine is located at the lower part of engine: can be disassembled, and the crankcase is sealed as the shell of oil storage tank, the oil sump is mostly punched from thin steel plate, the shape is relatively complex and generally adopts cast iron or aluminum alloy casting, its inside is equipped with oil stabilizing baffle to avoid the oil surface oscillation caused by diesel engine jolt, which is beneficial to the sedimentation of oil impurities, the side is equipped with oil gauge for checking oil quantity, in addition, the lowest part of the bottom of oil sump is also equipped with oil drain screw plug.
[0003] The existing diesel engine oil sump needs to pull out the whole screw plug during the oil draining process, and diesel oil is easy to splash during the process of pulling out the bolt, which is easy to splash on the body of the worker and cause scald, increases the occurrence of accidental incidents when the worker drains oil, the splashing of diesel oil also pollutes the environment, and for the function of the oil sump itself, it is used to contain engine oil, the engine oil provides lubrication for the transmission mechanism, the engine oil is sucked into the oil pipe by the suction cup, and the engine oil level needs to be higher than the inlet of the oil suction pipe during oil suction to avoid the air being sucked by the oil pump. The liquid level that the engine oil level is flush with the inlet of the oil suction pipe is called alarm liquid level. In order to prevent the engine oil level of the oil sump from being lower than the alarm liquid level, the existing solution is to add engine oil to the oil sump regularly.
[0004] Generally, the inlet of the oil suction pipe is located at the middle position in the length direction of the oil sump to ensure that the diesel engine can be reliably pumped as much as possible when any end is inclined to avoid air suction. When the diesel engine is in a horizontal state, the engine oil surface is parallel to the bottom surface of the oil sump body, the engine oil level is higher than the inlet of the oil suction pipe, and the oil can be normally pumped, but when the diesel engine is inclined, the engine oil level of the oil sump is inclined, a considerable amount of engine oil is formed at one end in the oil sump, and the engine oil level at the other end is close to or lower than the alarm liquid level, which is easy to cause air suction. Moreover, in order to ensure safety, it is necessary to continue to add engine oil, because the oil storage space of the oil sump is limited, and the amount of engine oil required to ensure the safety liquid level is relatively large, which leads to a great shortening of the engine oil filling period of the oil sump, increases the maintenance workload of the diesel engine, and urgently needs to be improved.

[0045] Further, the oil discharge control mechanism 4 comprises a screw rod 401 arranged at the lower end of the side wall 102 of the oil sump body 1, the diameter of the screw rod 401 is greater than that of the oil outlet hole 104, the screw rod 401 is located in the side wall 102 of the oil sump body 1 and penetrates through the oil outlet hole 104, the position opposite to the oil outlet hole 104 of the screw rod 401 is provided with an oil discharge hole 402, and the oil discharge hole 402 is communicated with or offset from the oil outlet hole 104 when the screw rod 401 rotates.
[0046] Further, one end of the screw rod 401 extends from the end of the side wall 102 of the oil sump body 1.
[0047] Further, the side wall 102 of the oil sump body 1 is provided with an extension 5 extending horizontally away from the inner cavity of the oil sump body 1, the upper surface of the extension 5 is provided with a recess 6, and the recess 6 is provided with an elastic sealing device 7.
[0048] Further, the elastic sealing device 7 comprises an elastic sealing strip 71, the upper end surface of the elastic sealing strip 71 protrudes from the upper surface of the extension part 5, and the lower end surface of the elastic sealing strip 71 is connected with the bottom surface of the groove 6 through a spring 72.

[0050] Further, the oil pan body 1 and the fin 8 are made of heat-conducting materials.
[0051] Further, the top end of each baffle plate 2 is located on the same horizontal plane as the upper end surface of the extension part 5.
[0052] The working principle of the utility model is as follows: the plurality of baffle plates 2 arranged in the inner cavity of the oil pan body 1 divide the inner cavity of the oil pan body 1 into a plurality of containing spaces, so that the oil does not produce large fluctuations, and the oil can effectively reduce the oscillation and splashing in the inner cavity of the oil pan body 1, which is conducive to the deposition of impurities in the oil; the communication holes 103 on the baffle plates 2 can effectively ensure the mutual flow of the oil in the containing spaces, so that the containing spaces can be smoothly filled with oil and drained; when the oil pan body 1 is in a horizontal state, the heights of the two floating balls 303 are the same, and the oil surfaces of the containing spaces are parallel to the bottom surface of the oil pan body 1; at this time, the matching holes 302 on the rotating shaft 301 are communicated with the communication holes 103 on the baffle plates 2, as long as the oil level is higher than the inlet of the oil suction pipe, normal oil suction can be realized; when the oil pan body 1 is inclined, the oil flows to the lower side, so the floating ball 303 on the lower side is immersed in the oil, and the floating ball 303 on the higher side is exposed; under the action of the oil buoyancy, the floating ball 303 on the lower side floats upwards, and the floating ball 303 on the higher side falls; when the two floating balls 303 respectively float upwards and fall, the rotating shaft 301 is automatically rotated through the connecting rod 304; in the process of rotation, the matching holes 302 and the communication holes 103 are gradually misaligned, and finally the communication holes 103 are completely blocked by the rotating shaft 301; at this time, the oil on the higher side of the oil pan body 1 stops flowing to the containing space on the lower side of the oil pan body 1, so the effect of preventing the oil level from being excessively inclined due to the inclination of the oil pan body 1 is realized, and the oil level on the higher side of the oil pan body 1 is ensured to be not lower than the normal oil suction level, so that the situation that the containing space on the higher side cannot normally suck oil due to the excessive inclination of the oil level is effectively prevented, and the oiling period of the oil pan oil is longer, and the maintenance workload of the explosion-proof diesel engine is smaller.
[0053] When the oil needs to be drained, the screw 401 is rotated so that the oil drain hole 402 on the screw 401 is connected to the oil outlet hole 104. At this time, the oil in the oil pan body 1 can be discharged through the oil outlet hole 104. When the oil drain operation is not needed, the screw 401 is rotated in the opposite direction so that the oil drain hole 402 on the screw 401 is staggered with the oil outlet hole 104. At this time, the oil outlet hole 104 is blocked by the screw 401, and the oil cannot be discharged from the oil outlet hole 104. The structure is simple and the operation is convenient.
[0054] Since one end of the screw 401 extends from the end of the side wall of the oil pan body 1, it is convenient for the screw 401 to be rotated, and the extended end is away from the oil outlet hole 104. Therefore, during the process of rotating the screw 401 to drain the oil, there is no risk of oil splashing onto the staff and causing burns or other accidents. Moreover, during the process of rotating the screw 401 to drain the oil, the connecting port between the oil drain hole 402 and the oil outlet hole 104 is gradually enlarged, and the oil discharge amount is also gradually increased from small to large, without causing sudden spraying, splashing, etc., and the safety performance is good.
