Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] Example:

[0025] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0026] A large-flow hydraulic oil source comprises an oil tank body 1, a control cabinet 2 is fixedly installed on the right end of the top of the oil tank body 1, a plurality of oil pump motors 3 are fixedly installed on the top of the oil tank body 1 and on the left side of the control cabinet 2, a mounting base 4 is fixedly installed below the oil tank body 1, a buffer assembly 5 is fixedly installed between the mounting base 4 and the oil tank body 1, a cooling water tank 6 is fixedly installed on the right side of the oil tank body 1, and a cooling coil 7 is fixedly installed on the bottom end of the inside of the oil tank body 1.

[0027] Firstly, a liquid level window 101 is provided at the left end of the front face of the oil tank body 1, a plurality of cleaning covers 102 are fixedly installed at the front face of the oil tank body 1, and an oil drain pipe 103 is fixedly connected to the bottom end of the front face of the oil tank body 1. When the oil tank body 1 is in use, the internal oil storage amount can be observed at any time through the liquid level window 101, and the cleaning cover 102 can be opened to facilitate cleaning and maintenance of the interior of the oil tank body 1, and the oil drain pipe 103 can discharge impurities and excess oil at the bottom end of the oil tank body 1.

[0028] Furthermore, a cooling fan 201 is fixedly installed on the right side of the control cabinet 2, and oil filters 301 are fixedly installed on the input ends of the multiple oil pump motors 3 and inside the oil tank body 1. The output ends of the multiple oil pump motors 3 are connected to the inside of the control cabinet 2 through the connecting pipe 302. The right end of the connecting pipe 302 is connected to the inside of the control cabinet 2 through the conduit 303. The cooling fan 201 is used to dissipate heat from the inside of the control cabinet 2 to ensure its normal operation. When pumping oil, the multiple oil pump motors 3 are filtered through the oil filter 301 and then discharged through the connecting pipe 302 and the conduit 303.

[0029] Then, the buffer assembly 5 includes a shock absorber 501 fixedly installed at the center of the mounting base 4, sliding rods 502 are fixedly installed at the four corners of the bottom of the oil tank body 1, and the outer sides of the multiple groups of sliding rods 502 are slidably connected with sliding sleeves 503, and the outer sides of the multiple groups of sliding rods 502 are sleeved with springs 504, and transmission rods 505 are installed between the multiple groups of sliding sleeves 503 and the mounting base 4. The shock absorber 501 and the multiple groups of transmission rods 505 are diagonally supported to ensure that the oil tank body 1 and the mounting base 4 are in contact when the multiple groups of oil pump motors 3 are not working. The stability between the mounting base 4 is enhanced, the top of the shock absorber 501 is fixedly connected to the bottom of the oil tank body 1, and the upper and lower ends of the transmission rod 505 are rotatably connected to the sliding sleeve 503 and the mounting base 4 respectively. When the multiple oil pump motors 3 are working, the shock absorber 501 is used to buffer the vibration. At the same time, the top ends of the multiple transmission rods 505 push the sliding sleeve 503, so that the sliding sleeve 503 squeezes the spring 504 to further buffer the vibration, thereby reducing the noise generated by the vibration and improving the overall stability and safety.

[0030] Secondly, a water filling cover 601 is threadedly connected to the top of the cooling water tank 6, and a drain pipe 602 is fixedly connected to the bottom end of the right side of the cooling water tank 6. Multiple sets of cooling fins 603 are fixedly connected to the right side of the cooling water tank 6, and the left ends of the multiple sets of cooling fins 603 extend to the interior of the cooling water tank 6. Water is added to the cooling water tank 6 through the water filling cover 601, and the remaining water in the cooling water tank 6 can also be discharged through the drain pipe 602. At the same time, when the cooling water tank 6 is in use, the internal water can also be cooled by the multiple sets of cooling fins 603 on the right side, so that the water in the cooling water tank 6 can maintain a good cooling effect.

[0031] Finally, a water pump 701 is fixedly installed at the bottom end of the front side of the cooling water tank 6, the input end of the water pump 701 is connected to the inside of the cooling water tank 6, the output end of the water pump 701 is fixedly connected to one end of the cooling coil 7, and the other end of the cooling coil 7 is fixedly connected to the top of the cooling water tank 6.

The cooling coil 7 can fully contact the oil inside the oil tank body 1, thereby continuously cooling and reducing the temperature, which greatly improves the heat dissipation effect.

[0032] In this embodiment, the implementation scenario is specifically as follows: the stability between the oil tank body 1 and the mounting base 4 is ensured when the multiple oil pump motors 3 are not working by means of the shock absorber 501 and the multiple transmission rods 505 diagonal braces, the top of the shock absorber 501 is fixedly connected to the bottom of the oil tank body 1, the upper and lower ends of the transmission rod 505 are rotatably connected to the sleeve 503 and the mounting base 4 respectively, and when the multiple oil pump motors 3 are working, the shock absorber 501 is used to buffer the vibration, and at the same time, the top ends of the multiple transmission rods 505 push the sleeve 503, so that the sleeve 503 squeezes the spring 504 to further buffer the vibration, thereby reducing the noise generated by the vibration, and water is added to the cooling water tank 6 through the water adding cover 601 to cool the cooling water tank 6. The remaining water in the water tank 6 can also be discharged through the drain pipe 602. At the same time, when the cooling water tank 6 is in use, the internal water can also be cooled through the multiple sets of cooling fins 603 on the right side, so that the water in the cooling water tank 6 can maintain a good cooling effect.
