Technical Field

[0001] The invention relates to the technical field of drilling machines, in particular to an integrated variable frequency motor with an adjusting gear. Background Art

[0003] Since Antarctica is very cold, existing motors need to be preheated in advance to increase power. The drill bit also needs to be preheated in advance because its strength will decrease at low temperatures. At the same time, the drill bit temperature needs to be constantly monitored to prevent the motor power from increasing too high at high temperature, or the drill bit from becoming brittle at low temperatures and causing the drill bit to break.

[0014] According to the above technical solution, the interior of the low-flow elastic ball is connected to the internal pipeline of the elastic block.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0016] (1) By setting up a flow valve and a rotating heating device, when the flow rate is small, only the low-flow ball floats up to connect the low-flow water outlet. When the flow rate is large, the high-flow ball floats up to connect the high-flow water outlet, which plays the effect of opening different water outlets according to the flow rate of the liquid. When the flow rate is small, it means that the temperature of the heat transfer oil and the motor is too low, and they enter the pipeline that heats up quickly. When the flow rate is large, it means that the temperature of the heat transfer oil and the motor is sufficient, and they enter the pipeline that heats the entire drilling machine, which plays the effect of automatically adjusting the flow direction of the heat transfer oil to adapt to different working stages;

[0017] (4) By providing a differential pressure valve, when the temperature difference between the drill bit and the motor is small, the drill bit and the motor are heated equally at the same time, thereby ensuring the power of the motor and the strength of the drill bit. When the temperature of the drill bit or the motor is too low, the heat transfer oil inlet of the fixed pipe is automatically adjusted to increase the heat of the heat transfer oil flowing in the direction of the lower temperature, and give priority to heating the lower temperature side, so as to quickly increase the power of the motor and the strength of the drill bit, thereby achieving the effect of automatically balancing the power of the motor and the strength of the drill bit, so that the working efficiency and strength of the drilling machine are steadily improved;

[0018] (3) By providing an elastic ring capsule, when the motor is just started, the heat transfer oil is automatically directed to the motor, and the motor is quickly heated to increase the power. After the motor reaches the appropriate power to drive the drill bit to rotate, when the temperature difference between the drill bit and the motor is not large, the heat transfer oil is normally directed to both ends for equal heating. When the temperature on one side is too low, more heat transfer oil is directed to the side with lower temperature, further improving the heating efficiency of the side with lower temperature, thereby avoiding insufficient hardness of the drill bit or a decrease in motor power.

[0019] (4) By providing a linkage device, when the motor drives the drill bit and the heating device to rotate through the linkage device, the elastic block clamps the ball and drives the drill bit to rotate. When the ice layer is too hard, the ball can press down the elastic block, causing idling, thereby achieving the effect of automatically protecting the drill bit;

[0020] (5) By connecting the low-flow elastic ball to the elastic block pipe, the strength of the elastic block can be proportional to the flow rate of the heat transfer oil. When the drilling machine is just started, the motor only drives the gear pump to deliver the heat transfer oil, fully heating the motor and increasing the motor power. After the motor reaches the appropriate temperature, the strength of the elastic block can also slightly drive the drill bit to rotate. Then, as the motor and the drill bit heat up, the flow rate of the heat transfer oil and the hardness of the drill bit gradually increase, and the strength of the elastic block also increases accordingly, so that the idling force of the linkage device on the drill bit can increase along with the hardness of the drill bit. While ensuring the drilling efficiency, the start timing of the protection measures is automatically adjusted according to the hardness of the drill bit. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0030] See also Figure 1-6 , the present invention provides a technical solution: Figure 1 An integrated variable frequency motor with an adjustable gear includes a drilling machine 1, the drilling machine 1 includes a housing 11, a motor 12 is arranged in the housing 11, a driving gear 13 is arranged on the output shaft of the motor 12, the driving gear 13 is meshed with a driven gear 14, the driving gear 13 and the driven gear 14 are combined into a gear pump 15, the input pipe of the gear pump 15 is connected to a heat transfer oil tank, the heat transfer oil tank is provided with heat transfer oil, the heat transfer oil is a low specific heat capacity liquid, the output pipe of the gear pump 15 is connected to a flow valve 2, a linkage device 3 is arranged on the rotating shaft of the driving gear 13, and the lower side of the linkage device 3 A drill bit 16 is provided, and a heating device 4 is provided in the linkage device 3. The motor 12 can drive the drill bit 16 to drill the ice layer through the linkage device 3. At the same time, the flow valve 2 can be drawn through the gear pump 15. When the motor 12 is just started, the motor can be preheated through the heating device 4. When the motor 12 reaches a suitable temperature, the flow direction is changed to heat the drill bit 16 and the motor 12 at the same time. The linkage device 3 automatically opens and closes the transmission between the motor 12 and the drill bit 16 according to the temperature of the motor 12 to prevent the drill bit from breaking. The heat transfer oil can be quickly heated and transfer the heat to the motor 12 and the drill bit 16;

[0031] like Figure 3The flow valve 2 includes a flow valve housing 21, a flow valve inlet is arranged on one side of the flow valve housing 21, a flow valve elastic bag 22 is arranged on the flow valve inlet, a high flow water outlet and a low flow water outlet are arranged at the bottom of the flow valve housing 21, a high flow ball 23 and a low flow ball 24 are arranged at the high flow water outlet and the low flow water outlet respectively, a high flow elastic ball 25 and a low flow elastic ball 26 are arranged in the high flow ball 23 and the low flow ball 24 respectively, the interior of the flow valve elastic bag 22 is connected with the internal pipeline of the high flow ball 23, low-density liquid is arranged in the flow valve elastic bag 22 and the high flow ball 23, the interior of the high flow elastic ball 25 is connected with the internal pipeline of the low flow ball 24, high-density liquid is arranged in the high flow elastic ball 25 and the low flow ball 24, hydraulic oil is arranged in the low flow elastic ball 26, and the heat transfer oil is in When entering the flow valve housing 21, it will impact the flow valve elastic capsule 22, squeeze the low-density liquid in the flow valve elastic capsule 22, and the low-density liquid enters the high-flow ball 23 to squeeze the high-flow elastic ball 25. The high-density liquid in the high-flow elastic ball 25 squeezes into the low-flow ball 24, squeezing the low-flow elastic ball 26 to discharge the hydraulic oil, so that the density of the high-flow ball 23 is reduced, and the density of the low-flow ball 24 is increased. When the flow rate is small, the impact force of the heat transfer oil is small, and the density changes of the high-flow ball 23 and the low-flow ball 24 are also small. Only the low-flow ball 24 floats up and conducts the low-flow water outlet. When the flow rate is large, the impact force of the heat transfer oil is large, and the density changes of the high-flow ball 23 and the low-flow ball 24 are also large, so that the high-flow ball 23 floats up and conducts the high-flow water outlet, which has the effect of opening different water outlets according to the flow rate of the liquid;

[0032] like Figure 5The heating device 4 includes a pressure differential valve 41, which includes a pressure differential valve pipeline 411. The pressure differential valve pipeline 411 is arranged at the end of the drill bit 16. Four sets of rotating heating devices 42 are arranged on the outer surface of the pressure differential valve pipeline 411. The rotating heating device 42 includes a plurality of rotating sleeves 421. The rotating sleeves 421 are each provided with a rotating friction block 422. A plurality of blades 423 are arranged between the rotating sleeves 421 and the rotating friction block 422. The adjacent blades 423 are inclined in opposite directions. A fixed pipe 43 is arranged on the outer surface of the rotating heating device 42. When the heat transfer oil flows into the fixed pipe 43, the adjacent rotating friction blocks 422 driven by the blades 423 can rotate in different directions. The heat is heated by the rotation and friction, and the heat transfer oil is then transferred to the drill bit 16 and the motor 12 by the heat transfer oil. At the same time, by adjusting the heat transfer oil input position, the heat transfer oil flowing to both sides can pass through different numbers of rotating heating devices 42, so that the drill bit 16 and the motor 12 can be heated at different efficiencies, so that the drill bit 16 or the motor 12 is heated first, and the effect of heating the heat transfer oil is achieved. The heat is transferred to the drill bit 16 and the motor 12 by the heat transfer oil, and the power of the motor 12 and the hardness of the drill bit 16 are increased. By adjusting the heat transfer oil input position, the heating efficiency of the heat transfer oil flowing to both sides can be changed, so that the drill bit 16 or the motor 12 is heated first.

[0033] like Figure 2 , the two ends of the fixed pipe 43 are respectively connected to the heating pipelines inside the drill bit 16 and the motor 12, and the low flow outlet of the flow valve 2 is connected to the pipe on the side of the fixed pipe 43 close to the drill bit 16. When the drilling machine 1 is just started, due to the low temperature, the power of the motor 12 is low, the heat transfer oil is relatively viscous, and the heat transfer oil flows slowly. It will flow out from the low flow outlet of the flow valve 2 and flow to the side of the fixed pipe 43 close to the drill bit 16. The heat transfer oil flowing to the motor 12 passes through all the rotating heating devices 42, and the rotating heating devices 42 heat the heat transfer oil and the motor 12, reducing the viscosity of the hot oil, making it easier for the hot oil to flow, increasing the power of the motor 12, and at the same time increasing the power of the gear pump 15, so as to achieve the goal of giving priority to heating the heat transfer oil and the motor 12 when the drilling machine 1 is just started, quickly increasing the power of the motor 12 and the heat transfer efficiency of the heat transfer oil, so as to heat the drilling machine 1 as a whole later and quickly start the drilling machine 1;

[0034] like Figure 2 and Figure 4, large elastic balls 412 are arranged on both sides of the differential pressure valve pipeline 411, small elastic balls 413 are arranged inside the large elastic balls 412, and the large elastic balls 412 are connected to the internal pipeline of the small elastic ball 413 of another differential pressure valve 41, and heat-sensitive grooves 414 are arranged inside the drill bit 16 and the motor 12, and the heat-sensitive grooves 414 are respectively connected to the internal pipelines of the adjacent large elastic balls 412, and heat-conducting liquids are arranged in the large elastic balls 412, the small elastic balls 413 and the heat-sensitive grooves 414. The inner wall in the middle of the differential pressure valve pipeline 411 is connected to the high-flow outlet pipeline, and the inner wall in the middle of the differential pressure valve pipeline 411 is also connected to the outer wall pipeline through the pressure valve, and the hydraulic oil and oil pressure in the large elastic ball 412 on one side can be transmitted to the large elastic ball 412 on the other side through the small elastic ball 413. 412, and avoid heat transfer of hydraulic oil on both sides. When the heat transfer oil and the motor 12 are heated to a suitable temperature, the heat transfer oil is completely dissolved, the motor 12 also rotates rapidly, and the heat transfer oil flows rapidly. At this time, the heat transfer oil will flow out from the high-flow outlet of the flow valve 2 and enter the middle of the differential pressure valve pipeline 411. If the temperature difference between the drill bit 16 and the motor 12 is not large, the large elastic ball 412 can block both ends of the differential pressure valve pipeline 411, and the heat transfer oil accumulates between the large elastic balls 412 and finally flows out from the pressure valve, so that the heat transfer oil flowing to the drill bit 16 and the motor 12 passes through the same number of rotating heating devices 42, so as to achieve the effect of heating the drill bit 16 and the motor 12 equally at the same time when the temperature difference between the drill bit 16 and the motor 12 is not large, thereby ensuring the power of the motor 12 and the strength of the drill bit 16;

[0035] like Figure 2 The large elastic ball 412 and the small elastic ball 413 are both made of cold-resistant rubber material with good heat insulation effect. An elastic net is arranged on the inner wall of the large elastic ball 412. Both ends of the differential pressure valve pipeline 411 are connected to the inner wall pipeline of the fixed pipe 43 close to the end through a one-way valve. The large elastic ball 412 and the small elastic ball 413 can maintain elasticity in a cold environment, while the elastic net will lose its elasticity and become harder in a cold environment. When the temperature difference between the drill bit 16 and the motor 12 is not large, the elasticity of the elastic nets on both sides is the same, and the extrusion force of the large elastic ball 412 and the expansion force of the small elastic ball 413 can offset each other, so that the heat transfer oil can accumulate between the large elastic balls 412. When the temperature of the drill bit 16 or the motor 12 is high, the heat transfer oil can accumulate between the large elastic balls 412. When the temperature of the drill bit 16 or the motor 12 is too low, the heating device 400 will automatically adjust the heat transfer oil inlet of the fixed pipe 43 to increase the heat transfer oil flow to the lower temperature side, thereby increasing the heat transfer oil flow to the lower temperature side.

[0036] like Figure 2 and Figure 4 , an elastic ring capsule 44 is arranged on the inner wall of the differential pressure valve pipeline 411, and the elastic ring capsule 44 is connected to the internal pipeline of the large elastic ball 412 on the other side. When the temperature difference between the drill bit 16 and the motor 12 is not large, the elastic ring capsule 44 does not change, and the heat transfer oil flows normally to both ends and is heated evenly. When the large elastic ball 412 on one side is squeezed and deformed, the hydraulic pressure in the large elastic ball 412 on the other side will increase, and the internal pressure will be synchronized to the elastic ring capsule 44 on the same side as the deformed large elastic ball 412, so that the elastic ring capsule 44 will increase, hindering the flow of the heat transfer oil on this side, and the greater the temperature difference, the larger the elastic ring capsule 44 is, so that more heat transfer oil flows to the side with lower temperature, further improving the heating efficiency of the side with lower temperature, so that the heating device 4 can quickly balance the temperature of the motor 12 and the drill bit 16. When just started, the motor 12 quickly heats the drill bit 16 after reaching the appropriate temperature, and avoids the drill bit 16 from being insufficiently hard or the motor 12 power from decreasing again during subsequent use;

[0037] like Figure 6 The elastic ring capsule 44 includes a motor elastic ring capsule 44-1 and a drill elastic ring capsule 44-2. The motor elastic ring capsule 44-1 and the drill elastic ring capsule 44-2 both include an elastic ring 441. The inner outer ring of the elastic ring 441 is provided with a plurality of counterweight blocks 442. A telescopic rod and a spring are provided between the counterweight blocks 442 of the drill elastic ring capsule 44-2 and the inner inner ring of the elastic ring 441 in the opposite oblique direction of the motor rotation direction. The outer jacket of the elastic ring 441 of the motor elastic ring capsule 44-1 is provided with an elastic rope, which will not drive the motor 12 when it is just started. The heating device 4 rotates, and the counterweight 442 is not subjected to force at this time. The elastic rope compresses the motor elastic ring capsule 44-1, and the telescopic rod and the spring expand the drill elastic ring capsule 44-2, so that when the drilling machine 1 is just started, the heat transfer oil all flows to the motor 12, and the motor 12 can quickly heat itself and increase the power. When the heating device 4 rotates, the centripetal force and centrifugal force of the counterweight 442 shrink the drill elastic ring capsule 44-2 and expand the motor elastic ring capsule 44-1, so that both sides are fully connected, so that the heating device 4 is convenient for preferentially heating the side with a lower temperature;

[0038] like Figure 3The linkage device 3 includes a transmission sleeve 31, which is arranged on the rotating shaft of the driving gear 13. The inner wall of the transmission sleeve 31 is rotatably connected with the outer wall of the fixed tube 43. The outer wall of the fixed tube 43 is provided with a plurality of balls 32. The inner wall of the transmission sleeve 31 is provided with a plurality of ball grooves 33. A plurality of elastic blocks 34 are provided between the ball grooves 33. The elastic blocks 34 are hollow structures. The balls 32 are stuck between the elastic blocks 34. When the motor 12 drives the drill bit 16 and the heating device 4 to rotate through the linkage device 3, the balls 32 will squeeze the elastic blocks 34. When the ice layer is soft, the elastic blocks 34 can clamp the balls 32 to drill holes quickly. When the ice layer hardens, the force between the elastic blocks 34 and the balls 32 increases. When the ice layer is too hard, the balls 32 can press down the elastic blocks 34 to cause idling, thereby achieving the effect of automatically protecting the drill bit 16.

[0039] like Figure 3 The interior of the low-flow elastic ball 26 is connected to the internal pipeline of the elastic block 34. The hydraulic oil squeezed in the low-flow elastic ball 26 will flow into the elastic block 34, making the elastic block 34 not easily flattened, achieving the effect that the strength of the elastic block 34 is proportional to the flow rate of the heat transfer oil. When the drilling machine 1 is just started, the flow rate of the heat transfer oil is the slowest, and the strength of the elastic block 34 is the smallest. The motor 12 only drives the gear pump 15 to transport the heat transfer oil, fully heats the motor 12, and increases the power of the motor 12. After the motor 12 reaches a suitable temperature, the strength of the elastic block 34 can also slightly drive the drill bit 16 to rotate. Then, as the motor 12 and the drill bit 16 heat up, the flow rate of the heat transfer oil and the hardness of the drill bit 16 will also increase, and the strength of the elastic block 34 will also increase accordingly, so that the idling force of the linkage device 3 on the drill bit 16 can increase together with the hardness of the drill bit 16, while ensuring the drilling efficiency, the start timing of the protection measure is automatically adjusted according to the hardness of the drill bit 16.
