However, the oil tanks currently on the market may have low internal temperature or the oil in the oil tank is different for a long time, which leads to reduced fluidity of the oil. When the oil is extracted and injected by hydraulic means, the power system cannot be supplied with oil in a timely and fast manner due to the problem of oil fluidity, resulting in unstable operation of the power system.

[0006] The present invention further illustrates that a buffer cavity is fixed on the right side of the inner wall of the hydraulic cavity, a buffer plate is slidably connected to the inner wall of the buffer cavity, the right side portion of the gear rod is hollow, and a slider is slidably connected to the inner wall, a connecting rod is fixedly connected between the slider and the buffer plate, a buffer spring is fixed between the buffer plate and the right side of the inner wall of the buffer cavity; an extrusion spring is arranged on the left side of the slider.

[0007] The present invention further illustrates that two through holes are arranged on the surface of the buffer plate, the bottom of the chamber is connected to the right pipeline of the buffer cavity, and the bottom of the sliding plate is filled with hydraulic oil.

[0008] The present invention further describes that the inner walls of the main oil tank and the auxiliary oil tank are fixedly installed with telescopic joints, the right end of the telescopic joint is spherical and located on the outside of the gear plate, and the telescopic joint contacts the outside of the gear plate after being extended, and the left side of the hollow part of the gear rod is connected to the pipe between the telescopic joint.

The lower the temperature, the worse the fluidity of the oil, so that the torque of the motor is greater, thereby increasing the strength of extracting and discharging the oil. On the one hand, the torque of the motor is reduced when the temperature is high, thereby ensuring smooth extraction of the oil and reducing energy consumption. On the other hand, when the temperature is low, the fluidity of the oil is poor, thereby increasing the torque of the motor and increasing the extraction strength, so that the oil can be quickly injected into the power system to avoid the power system being unable to be driven by the oil in time and thus reducing the running speed, thereby improving the running stability of the power system.

[0012] At the same time, the stirring blade stirs the oil, thereby preventing the fluidity of the oil from being reduced due to low temperature or long-term non-use of the oil, making it easier for the hydraulic chamber to extract the oil, so that the power system can be replenished with oil more timely and run more stably. The movement of the gear rod is buffered by the extrusion spring and the buffer spring, avoiding the large torque of the motor causing the gear rod to move faster and the motor cannot be braked quickly, resulting in the amount of oil extracted fluctuating. This can further improve the stability of the oil delivery of the power system, and the power system can also run relatively more stably, improving the accuracy of the oil injection amount;

[0013] And when the torque of the motor reaches its maximum, the gear disk drives the stirring blade to shake slightly left and right through the pin shaft, shaking the oil in the main oil tank and the auxiliary oil tank. Since the oil temperature is low at this time and the fluidity is extremely poor, the shaking can further play an anti-freeze role to ensure its fluidity, and the small shaking amplitude is not easy to produce noise.

DETAILED DESCRIPTION

[0024] The following is a further non-limiting detailed description of the technical solution of the present invention in conjunction with the preferred embodiments and the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] See also Figure 1-8 The present invention provides a technical solution: an antifreeze split oil tank based on a hydraulic power system, comprising a split oil tank and a hydraulic power mechanism, wherein the split oil tank comprises a main oil tank 1 and a subsidiary oil tank 2, and an oil pipe 3 is connected to the bottom of the main oil tank 1 and the bottom of the subsidiary oil tank 2;

[0026] The hydraulic power mechanism includes a hydraulic chamber 4, a hydraulic plate 41, a gear rod 42, a motor 43 and a gear 431. The left side of the hydraulic chamber 4 is connected to the oil pipe 3, and a one-way valve 1 is arranged in the pipe. The left side of the hydraulic chamber 4 is connected to the power system pipe, and a one-way valve 2 is arranged in the pipe. The hydraulic plate 41 is slidably connected to the inner wall of the hydraulic chamber 4, the motor 43 is fixedly installed on the inner wall of the hydraulic chamber 4, the gear 431 is fixedly connected to the output end of the motor 43, the gear rod 42 is fixedly installed on the right side of the hydraulic plate 41, and a plurality of gear blocks are arranged on the upper side, and the gear 431 is meshed with the gear 431 through the plurality of gear blocks.

[0027] A temperature detector is provided inside the main oil tank 1 and the auxiliary oil tank 2, and a temperature identification module is provided inside the temperature detector. A torque control module is provided inside the motor 43. The temperature identification module is electrically connected to the torque control module. The temperature identification module is used to identify the temperature inside the oil tank through the temperature detector. The torque control module is used to control the torque of the motor 43 according to the temperature inside the oil tank.

[0028] The oil is stored in the main oil tank 1 and the auxiliary oil tank 2. The motor 43 runs, driving the gear 431 to rotate. The gear 431 drives the gear rod 42 to move to the right through meshing. The gear rod 42 drives the hydraulic plate 41 to slide to the right along the inner wall of the hydraulic chamber 4. Negative pressure is generated on the left side of the hydraulic plate 41 to extract the oil in the main oil tank 1 and the auxiliary oil tank 2 through the oil pipe 3. Then the motor 43 rotates in the opposite direction to reset the hydraulic plate 41 and inject the extracted oil into the power system through the pipeline. During the storage of the oil, the temperature of the oil inside the main oil tank 1 and the auxiliary oil tank 2 is identified by the temperature recognition module of the temperature detector. The torque of the motor 43 is controlled according to the temperature. The lower the temperature, the worse the fluidity of the oil, which makes the torque of the motor 43 larger, thereby increasing the force of extracting and discharging the oil. On the one hand, when the temperature is high, the torque of the motor 43 is reduced, thereby ensuring smooth extraction of the oil and reducing energy consumption. On the other hand, when the temperature is low, the fluidity of the oil is poor, so the torque of the motor 43 is increased and the extraction force is strengthened, so that the oil can be quickly injected into the power system to avoid the power system being unable to obtain oil drive in time, thereby reducing the operating speed, thereby improving the operating stability of the power system.

[0029] The main oil tank 1 and the auxiliary oil tank 2 are both provided with an antifreeze mechanism, which includes two sleeves 5, a pin 51, a stirring blade 52, a toothed disc 53, a chamber 54, a sliding plate 541 and a toothed plate 542;

[0030] The stirring blade 52 is fixedly installed on the outside of the pin shaft 51, the two sleeves 5 are respectively fixedly installed on the left and right sides of the inner wall of the main oil tank 1, the pin shaft 51 is inserted between the two sleeves 5 and movably connected with the sleeves 5, the chamber 54 is fixedly installed on the upper part of the inner wall of the main oil tank 1, the sliding plate 541 is slidably connected to the inner wall of the chamber 54, the tooth plate 542 is fixedly installed below the sliding plate 541, and the toothed disc 53 is fixedly installed on the outer side of the left end of the pin shaft 51 and meshes with the toothed disc 542;

[0031] The upper part of the chamber 54 is connected to the right pipe of the hydraulic chamber 4;

[0032] Through the above steps, when the hydraulic plate 41 slides to the right along the inner wall of the hydraulic chamber 4, the gas on the right side of the hydraulic plate 41 enters the chamber 54 through the pipeline, and the sliding plate 541 is squeezed and slides downward along the inner wall of the chamber 54, thereby driving the tooth plate 542 to move downward, and the tooth plate 542 drives the toothed disc 53 to rotate through meshing, and the toothed disc 53 drives the stirring blade 52 to rotate through the pin shaft 51, and the stirring blade 52 stirs the oil, thereby avoiding the reduction of the fluidity of the oil due to low temperature or long-term non-use of the oil, making it easier for the hydraulic chamber 4 to extract the oil, and the power system can be replenished with oil more timely and run more stably.

[0033] A buffer chamber 44 is fixed to the right side of the inner wall of the hydraulic chamber 4, a buffer plate 441 is slidably connected to the inner wall of the buffer chamber 44, the right side of the gear rod 42 is hollow, and a slider 421 is slidably connected to the inner wall, a connecting rod 442 is fixedly connected between the slider 421 and the buffer plate 441, and a buffer spring 443 is fixed between the buffer plate 441 and the right side of the inner wall of the buffer chamber 44;

[0034] A pressing spring 422 is provided on the left side of the slider 421;

[0035] When the gear rod 42 moves to the right, the connecting rod 442 is driven to move to the right through the slider 421, and the connecting rod 442 drives the buffer plate 441 to slide to the right along the inner wall of the buffer chamber 44, and the buffer spring 443 is deformed by the force, thereby generating a reaction force. At the same time, the extrusion spring 422 is deformed by the force of the slider 421, and the movement of the gear rod 42 is buffered by the extrusion spring 422 and the buffer spring 443, so as to avoid the gear rod 42 moving faster due to the large torque of the motor 43, and the motor 43 cannot be braked quickly, resulting in the amount of oil extracted fluctuating, which can further improve the stability of the oil output of the power system, and the operation of the power system can also be relatively more stable, thereby improving the accuracy of the oil injection amount.

[0036] The surface of the buffer plate 441 is provided with two through holes 444 , the lower part of the chamber 54 is connected to the right pipe of the buffer chamber 44 , and the lower part of the sliding plate 541 is filled with hydraulic oil;

[0037] At the same time, when the sliding plate 541 slides downward, the hydraulic oil at the bottom thereof is squeezed and enters the buffer chamber 44 through the pipe. When the buffer plate 441 moves to the right, the hydraulic oil flows back and forth between the left and right sides of the buffer plate 441 through the through hole 444, thereby further buffering the buffer plate 441 through the hydraulic oil, further improving the accuracy of the oil extraction amount, and the greater the torque of the motor 51, the greater the impact force of the hydraulic oil entering the buffer chamber 44, thereby increasing the buffer strength and improving the buffer effect.

[0038] The inner walls of the main oil tank 1 and the auxiliary oil tank 2 are fixedly installed with a telescopic joint 6. The right end of the telescopic joint 6 is spherical and located on the outside of the gear plate 53. After the telescopic joint 6 is extended, it contacts the outside of the gear plate 53. The left side of the hollow part of the gear rod 42 is connected to the telescopic joint 6 by a pipe.

[0039] The elastic force of the pressing spring 422 is greater than the elastic force of the buffer spring 443 .

[0040] A movable spring 55 is arranged inside the sleeve 5, and the width of the toothed disc 53 is twice the width of the toothed plate 542;

[0041] When the slider 421 is affected by the force of the connecting rod 442, the extrusion spring 422 is deformed by the force. Since the elastic force of the extrusion spring 422 is greater than the elastic force of the buffer spring 443, the buffer strength reaches the maximum only when the torque of the motor 43 is maximized, and the deformation of the buffer spring 443 is the maximum, which increases the deformation of the extrusion spring 422 and increases the amplitude of the movement of the slider 421 to the left. The gas on its left side is squeezed and enters the telescopic joint 6 through the pipeline, causing it to stretch and push the toothed disc 53 to move. The toothed disc 53 drives the stirring blade 52 to shake slightly left and right through the pin shaft 51, thereby shaking the oil in the main oil tank 1 and the auxiliary oil tank 2. Since the oil temperature is low at this time and the fluidity is extremely poor, the shaking further plays an anti-freezing role to ensure its fluidity, and the small shaking amplitude is not easy to generate noise.
