Description
Technical Field
[0001] The present invention belongs to the technical field of fuel tanks, and particularly relates to an anti-freezing split fuel tank based on a hydraulic power system. Background Technique
[0002] Generally, the oil supply method of a hydraulic power system is to extract and inject the oil in the fuel tank into the power system through hydraulic means to provide power. However, currently on the market, the fuel tank may have problems such as low temperature inside the fuel tank or long-term difference in the oil in the fuel tank, resulting in a decrease in the fluidity of the oil. When extracting and injecting the oil through hydraulic means, the power system cannot be supplied with oil in a timely and rapid manner due to the fluidity problem of the oil, leading to unstable operation of the power system. This phenomenon has become an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides the following technical solution: An anti-freezing split fuel tank based on a hydraulic power system, including a split fuel tank and a hydraulic power mechanism. The split fuel tank includes a main fuel tank and a secondary fuel tank, and a fuel pipe is connected to the bottom of the main fuel tank and the bottom of the secondary fuel tank; the hydraulic power mechanism includes a hydraulic chamber, a hydraulic plate, a rack, a motor, and a gear. The left side of the hydraulic chamber is connected to the fuel pipe through a pipeline, and a one-way valve I is provided in the pipeline. The left side of the hydraulic chamber is connected to the power system through a pipeline, and a one-way valve II is provided in the pipeline. The hydraulic plate is slidably connected to the inner wall of the hydraulic chamber. The motor is fixedly installed on the inner wall of the hydraulic chamber. The gear is fixedly connected to the output end of the motor. The rack is fixedly installed on the right side of the hydraulic plate, and a number of tooth blocks are provided above, and the rack meshes with the gear through a number of tooth blocks; Temperature detectors are provided inside both the main fuel tank and the secondary fuel tank, and a temperature recognition module is provided inside the temperature detector. A torque control module is provided inside the motor. The temperature recognition module is electrically connected to the torque control module. The temperature recognition module is used to recognize the temperature inside the fuel tank through the temperature detector, and the torque control module is used to control the torque of the motor according to the temperature inside the fuel tank.
[0005] The present invention is further described as follows. Anti-freezing mechanisms are provided inside both the main fuel tank and the auxiliary fuel tank. The anti-freezing mechanism includes two sleeves, a pin shaft, stirring blades, a toothed disc, a chamber, a sliding plate, and a toothed plate. The stirring blades are fixedly installed outside the pin shaft. The two sleeves are respectively fixedly installed on the left and right sides of the inner wall of the main fuel tank. The pin shaft penetrates between the two sleeves and is movably connected to the sleeves. The chamber is fixedly installed above the inner wall of the main fuel tank. The sliding plate is slidably connected to the inner wall of the chamber. The toothed plate is fixedly installed below the sliding plate. The toothed disc is fixedly installed outside the left end of the pin shaft and meshes with the toothed plate. The upper part of the chamber is connected to the right side of the hydraulic chamber through a pipeline.
[0006] The present invention is further described as follows. A buffer chamber is fixed to the right side of the inner wall of the hydraulic chamber. A buffer plate is slidably connected to the inner wall of the buffer chamber. The right part of the toothed 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 chamber. An extrusion spring is arranged on the left side of the slider.
[0007] The present invention is further described as follows. Two through holes are provided on the surface of the buffer plate. The lower part of the chamber is connected to the right side of the buffer chamber through a pipeline. The lower part of the sliding plate is filled with hydraulic oil.
[0008] The present invention is further described as follows. Expansion joints are fixedly installed on the inner walls of both the main fuel tank and the auxiliary fuel tank. The right end of the expansion joint is spherical and is located outside the toothed disc. After the expansion joint extends out, it contacts the outside of the toothed disc. The left side of the hollow part of the toothed rod is connected to the expansion joint through a pipeline.
[0009] The present invention is further described as follows. The elastic force of the extrusion spring is greater than the elastic force of the buffer spring.
[0010] The present invention is further described as follows. A movable spring is arranged inside the sleeve. The width of the toothed disc is twice the width of the toothed plate.
[0011] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: The present invention controls the torque of the motor according to the temperature. The lower the temperature, the worse the fluidity of the oil, so that the torque of the motor is greater, thereby strengthening the force for pumping and discharging the oil. On the one hand, when the temperature is relatively high, the torque of the motor is reduced, so as to ensure smooth pumping of the oil and reduce energy consumption. On the other hand, when the temperature is relatively low and the fluidity of the oil is poor, the torque of the motor is increased to strengthen the pumping force, so that the oil can be quickly injected into the power system to avoid the power system not being able to obtain oil drive in time and thus reducing the operating speed, and improving the operating stability of the power system.
[0012] Meanwhile, the stirring blade agitates the oil fluid, thus preventing the fluidity of the oil fluid from decreasing due to low temperature or long-term non-use of the oil fluid, facilitating the smoother extraction of the oil fluid by the hydraulic cavity, enabling the power system to be replenished with oil fluid more promptly, running more stably, and buffering the movement of the toothed rod through the compression spring and the buffer spring, avoiding the relatively fast moving speed of the toothed rod caused by the large torque of the motor and the inability of the motor to quickly brake, resulting in a large or small amount of extracted oil fluid. It can further improve the stability of the oil supply volume to the power system, and the power system can operate relatively more stably, improving the accuracy of the oil injection volume.
[0013] And when the torque of the motor reaches the maximum, the toothed disc drives the stirring blade to swing slightly left and right through the pin shaft, agitating the oil fluid in the main fuel tank and the auxiliary fuel tank. Since the oil fluid temperature is relatively low at this time and the fluidity is extremely poor, the anti-freezing effect is further achieved through the swinging to ensure its fluidity, and the small swinging amplitude is not likely to generate noise.

Specific embodiments
[0024] The following further non-limiting detailed description of the technical solution of the present invention is made in conjunction with the preferred embodiments and their accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work shall fall within the protection scope of the present invention.
[0025] Please refer to Figure 1-8 , the present invention provides a technical solution: an anti-freezing split fuel tank based on a hydraulic power system, including a split fuel tank and a hydraulic power mechanism. The split fuel tank includes a main fuel tank 1 and an auxiliary fuel tank 2, and an oil pipe 3 is connected to the bottom of the main fuel tank 1 and the bottom of the auxiliary fuel tank 2;
[0026] The hydraulic power mechanism includes a hydraulic chamber 4, a hydraulic plate 41, a rack 42, a motor 43 and a gear 431. The left side of the hydraulic chamber 4 is connected to the oil pipe 3 through a pipeline, and a check valve one is arranged in the pipeline. The left side of the hydraulic chamber 4 is connected to the power system through a pipeline, and a check valve two is arranged in the pipeline. 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 rack 42 is fixedly installed on the right side of the hydraulic plate 41, and a plurality of tooth blocks are arranged above, and are engaged with the gear 431 through the plurality of tooth blocks;
[0027] Temperature detectors are arranged inside both the main fuel tank 1 and the auxiliary fuel tank 2, and a temperature recognition module is arranged inside the temperature detector. A torque control module is arranged inside the motor 43. The temperature recognition module is electrically connected to the torque control module. The temperature recognition module is used to recognize the temperature inside the fuel tank through the temperature detector, and the torque control module is used to control the torque of the motor 43 according to the temperature inside the fuel tank;
[0028] The oil is stored in the main fuel tank 1 and the auxiliary fuel tank 2. The motor 43 operates to drive the gear 431 to rotate. The gear 431 drives the rack 42 to move to the right through meshing. The rack 42 drives the hydraulic plate 41 to slide to the right along the inner wall of the hydraulic chamber 4. A negative pressure is generated on the left side of the hydraulic plate 41 to extract the oil in the main fuel tank 1 and the auxiliary fuel tank 2 through the oil pipe 3. Then the motor 43 rotates in the reverse 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 in the main fuel tank 1 and the auxiliary fuel tank 2 is identified by the temperature recognition module of the temperature detector, and the torque of the motor 43 is controlled according to the temperature. The lower the temperature, the worse the fluidity of the oil, so that the torque of the motor 43 is greater, and the strength of extracting and discharging the oil is enhanced. On the one hand, when the temperature is relatively high, the torque of the motor 43 is reduced, so as to ensure smooth oil extraction and reduce energy consumption. On the other hand, when the temperature is relatively low, the fluidity of the oil is poor, so the torque of the motor 43 is increased to strengthen the extraction force, so that the oil can be quickly injected into the power system to avoid the reduction of the operating speed of the power system due to the inability to obtain oil drive in time, and improve the operating stability of the power system.
[0029] Antifreeze mechanisms are arranged inside both the main fuel tank 1 and the auxiliary fuel tank 2. The antifreeze mechanisms include two sleeves 5, pin shafts 51, stirring blades 52, gear discs 53, chambers 54, sliding plates 541 and toothed plates 542;
[0030] The stirring blades 52 are fixedly installed on the outer sides of the pin shafts 51. The two sleeves 5 are respectively fixedly installed on the left and right sides of the inner wall of the main fuel tank 1. The pin shafts 51 are inserted between the two sleeves 5 and are movably connected to the sleeves 5. The chamber 54 is fixedly installed above the inner wall of the main fuel tank 1. The sliding plate 541 is slidably connected to the inner wall of the chamber 54. The toothed plate 542 is fixedly installed below the sliding plate 541. The gear disc 53 is fixedly installed on the outer side of the left end of the pin shaft 51 and meshes with the toothed plate 542;
[0031] The upper part of the chamber 54 is connected to the right side pipeline 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. The sliding plate 541 is squeezed and slides downward along the inner wall of the chamber 54, thereby driving the toothed plate 542 to move downward. The toothed plate 542 drives the gear disc 53 to rotate through meshing. The gear disc 53 drives the stirring blades 52 to rotate through the pin shaft 51. The stirring blades 52 stir the oil, so as to avoid the reduction of the fluidity of the oil caused by low temperature or long-term non-use of the oil, facilitate the smoother extraction of oil by the hydraulic chamber 4, make the power system obtain oil supplement more timely, and operate more stably.
[0033] On the right side of the inner wall of the hydraulic chamber 4, a buffer chamber 44 is fixed. A buffer plate 441 is slidably connected to the inner wall of the buffer chamber 44. The right part of the rack 42 is hollow, and a slider 421 is slidably connected to its inner wall. A connecting rod 442 is fixedly connected between the slider 421 and the buffer plate 441. 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 compression spring 422 is arranged on the left side of the slider 421;
[0035] When the rack 42 moves to the right, the connecting rod 442 is driven to move to the right through the slider 421. The connecting rod 442 drives the buffer plate 441 to slide to the right along the inner wall of the buffer chamber 44. The buffer spring 443 deforms under force, thus generating a reaction force. At the same time, the compression spring 422 deforms under the action of the slider 421. The movement of the rack 42 is buffered by the compression spring 422 and the buffer spring 443, avoiding the situation that the moving speed of the rack 42 is too fast due to the large torque of the motor 43 and the motor 43 cannot brake quickly, resulting in the amount of oil extracted being large and small. It can further improve the stability of the oil delivery volume of the power system, and the power system can operate relatively more stably, improving the accuracy of the oil injection volume.
[0036] Two through holes 444 are arranged on the surface of the buffer plate 441. The lower part of the chamber 54 is connected to the right side of the buffer chamber 44 through a pipeline. The lower part of the sliding plate 541 is filled with hydraulic oil;
[0037] And at the same time, when the sliding plate 541 slides downward, the hydraulic oil at its bottom is squeezed and enters the buffer chamber 44 through the pipeline. When the buffer plate 441 moves to the right, the hydraulic oil flows back and forth on the left and right sides of the buffer plate 441 through the through holes 444, thus further buffering the buffer plate 441 through the hydraulic oil, further improving the accuracy of the oil extraction volume. And the greater the torque of the motor 51, the greater the impact force of the hydraulic oil entering the buffer chamber 44, so the buffering strength is greater, improving the buffering effect.
[0038] Expansion joints 6 are fixedly installed on the inner walls of both the main fuel tank 1 and the auxiliary fuel tank 2. The right end of the expansion joint 6 is spherical and is located outside the toothed disc 53. After the expansion joint 6 extends, it contacts the outside of the toothed disc 53. The left side of the hollow part of the rack 42 is connected to the expansion joint 6 through a pipeline.
[0039] The elastic force of the compression spring 422 is greater than the elastic force of the buffer spring 443.
[0040] An active spring 55 is arranged inside the sleeve 5. 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 acting force of the connecting rod 442, the extrusion spring 422 is deformed under force. Since the elastic force of the extrusion spring 422 is greater than that of the buffer spring 443, only when the torque of the motor 43 reaches the maximum, the buffering strength reaches the maximum, the deformation degree of the buffer spring 443 is the largest, the deformation degree of the extrusion spring 422 is increased, and the moving amplitude of the slider 421 to the left increases. The gas on its left is squeezed and enters the expansion joint 6 through the pipeline, causing it to elongate and push the gear disk 53 to move. The gear disk 53 drives the stirring blade 52 to swing slightly left and right through the pin shaft 51, shaking the oil in the main fuel tank 1 and the auxiliary fuel tank 2. Since the oil temperature is relatively low at this time and the fluidity is extremely poor, the anti-freezing effect is further achieved through shaking to ensure its fluidity, and the small shaking amplitude is not easy to generate noise.

[0043] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
