[0037] In order to make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments of the present disclosure. Based on the described embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without any creative work fall within the scope of protection of the present disclosure.

[0038] Unless otherwise defined, technical terms or scientific terms used in the present disclosure shall have the same meaning as commonly understood by one of ordinary skill in the art to which this present disclosure belongs. Unless otherwise defined, the technical terms or scientific terms used in the present disclosure shall have the same meaning as commonly understood by one of ordinary skill in the art to which this present disclosure belongs. The terms "first", "second", and similar terms are not intended to denote any order, quantity, or importance, but are used to distinguish different components. The terms "include" or "contain" or similar terms mean that the elements or objects before the terms encompass the elements or objects listed after the terms and their equivalents, and do not exclude other elements or objects. The terms "connected" or "connected" or similar terms are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. The terms "up", "down", "left", "right", and the like are only used to represent relative positional relationships, and when the absolute positions of the described objects change, the relative positional relationships may also change accordingly.

[0039] Since the turbine engine can be directly fueled with natural gas, and has the advantages of small size, light weight, and high power density, etc., in the field of fracturing equipment, compared with using a diesel engine for driving, using a turbine engine for driving not only helps to reduce the size of the fracturing equipment, but also has the advantages of environmental protection, driving efficiency, etc.; compared with directly using an electric motor for driving, using a turbine engine for driving can reduce the power supply pressure of the fracturing operation site. In addition, the turbine engine also has the advantages of small size, light weight, and high power density.

[0040] On the other hand, the turbine engine is an engine that uses fluid impact on the impeller to rotate to generate power. Therefore, the impeller and the blade of the turbine engine need to be kept clean to prevent debris from damaging the balance of the impeller or damaging the impeller, thereby causing the equipment to malfunction.

[0041] At least one embodiment of the present disclosure provides a fracturing equipment comprising a power device. The power device comprises a silencer cabin, a turbine engine, an air inlet device, and a cleaning device; the air inlet device is connected to the turbine engine through an air inlet pipeline and is configured to provide combustion-supporting gas to the turbine engine; the cleaning device is configured to clean the turbine engine; the air inlet device is located at the top of the silencer cabin, and the silencer cabin has a containing space, the turbine engine and the cleaning device are located in the containing space, and the cleaning device is located on the side of the turbine engine away from the air inlet device.

[0042] The fracturing equipment provided by at least one embodiment of the present disclosure has the advantages that by arranging the air inlet device of the turbine engine above (the highest position) the turbine engine, the air inlet device is facilitated to take in air, and by arranging the cleaning device below the turbine engine, the fracturing equipment is arranged in three layers, i.e., top, middle, and bottom, so that the structure is more compact, the occupied volume is smaller, and transportation is facilitated. In addition, by arranging the turbine engine in the silencer cabin, noise reduction is facilitated.

[0043] For example, "below" in the embodiments of the present disclosure does not necessarily mean directly below, but can also mean obliquely below.

[0044] In at least one embodiment, the cleaning device is directly driven by electricity, i.e., directly driven by an electric motor, so that the occupied volume of the cleaning device can be effectively reduced, and the cleaning device can be placed below the turbine engine. For example, the highest point of the cleaning device is below the lowest point of the turbine engine, so that the cleaning device does not block the turbine engine in the height direction, thereby facilitating the maintenance of the turbine engine.

[0045] In other examples, the cleaning device can also be driven by a gas circuit or by hydraulic pressure. The embodiments of the present disclosure do not limit the driving mode of the cleaning device.

[0046] Figure 1 A schematic structural view of the fracturing equipment is provided for at least one embodiment of the present disclosure, which is, for example, a side view.

[0047] As shown in Figure 1 The fracturing equipment 5 includes a power device 1. The power device 1 includes a silencer cabin 11, a turbine engine 12, an air inlet device 13, and a cleaning device 14.

[0048] The silencer cabin 11 has a containing space 110, and the turbine engine 12 and the cleaning device 14 are located in the containing space 110. For example, the inner wall of the silencer cabin is provided with soundproofing cotton or soundproofing boards or other soundproofing devices.

[0049] The air inlet device 13 is located at the top of the silencer cabin 11 and is in communication with the turbine engine 12 through an air inlet pipeline 131 and is configured to provide combustion-supporting gas to the turbine engine 12. For example, the air inlet device 13 includes an air inlet filter and an air inlet silencer, one end of which is connected to the air inlet filter, and the other end of which is in communication with the air inlet pipeline 131.

[0050] For example, the air inlet device 13 includes a plurality of air inlet cabins 132 arranged side by side. The plurality of air inlet cabins 132 help to increase the volume of the air inlet device 13, not only having a larger gas capacity, thereby improving the power of the turbine engine 12, but also helping to reduce the resistance of the inlet and exhaust gas, thereby helping to prolong the service life of the turbine engine.

[0051] For example, the air inlet device 13 extends beyond the range of the silencer cabin 11 in the axial direction of the turbine engine, which not only helps to increase the volume of the air inlet cabin, but also protects the structure below (such as the air inlet assembly and the air outlet assembly described below) from being blocked (such as being protected from rain). It should be noted that the axial direction of the turbine engine described above can be the extension direction of the transmission shaft or the output shaft in the turbine engine.

[0052] For example, the air intake device 13 is fixed on the top of the muffler cabin 11 by welding or the like.

[0053] For example, the cleaning device 14 is located on the side of the turbine engine 12 away from the air intake device 13, i.e. below the turbine engine. For example, the cleaning device 14 can be located directly below or obliquely below the turbine engine 12. For example, the cleaning device 14 comprises a water tank 141 and a cleaning pump 142; for example, the cleaning device 14 is driven by electricity, which can reduce the space occupied by the cleaning device. In other examples, the cleaning device can be driven by an air compressor, for example, the air compressor is located outside the muffler cabin, and the air compressor can be driven by electricity, for example; in still other examples, the cleaning device can be driven by a hydraulic system, which can be driven by electricity, for example.

[0054] For example, the power device 1 further comprises a starting device located in the muffler cabin 11, and the starting device is configured to start the turbine engine 12.

[0055] For example, the starting device comprises an electric motor. For example, the electric motor is used to directly start the turbine engine 12, i.e. the turbine engine is started by electricity. In this case, for example, as shown in Figure 2 , the starting device 121 is integrated in the turbine engine.

[0056] Compared with directly driving the fracturing pump device by electricity, the electricity required to start the turbine engine is much smaller, which reduces the power supply demand of the fracturing operation site.

[0057] In other examples, the turbine engine 12 comprises a hydraulic system, and the electric motor in the starting device is used to drive the hydraulic system to start the turbine engine, i.e. the hydraulic system is driven by electricity. For example, the electric motor is located on the side of the turbine engine 12 away from the air intake device.

[0058] Compared with using diesel to drive the hydraulic system, the electric motor occupies less space, so it can be placed below the turbine engine.

[0059] For example, the hydraulic system comprises a hydraulic pump, a hydraulic motor, various valves, a hydraulic oil tank, a hydraulic oil radiator, etc.; for example, the hydraulic system is configured to drive the fuel pump, the starting motor, etc. of the turbine engine 12 under the drive of the electric motor to start the turbine engine 12.

[0060] For example, the power device further comprises a first lubricating system 122, and the first lubricating system 122 is configured to lubricate the turbine engine 12. Figure 2 The schematic diagram of the turbine engine 12 is schematically shown, as Figure 2As shown, the first lubrication system 122 is integrated into the turbine engine 12.

[0061] The first lubrication system 122 includes a first lubricating oil tank 122a and a first drive mechanism 122b, the first drive mechanism including an electric motor, that is, the first lubrication system is electrically driven.

[0062] For example, such as Figure 1 As shown, the power unit 1 also includes a reduction gear 16 and a second lubrication system 161 located within the anechoic chamber 11. The second lubrication system 161 is configured to lubricate the reduction gear 16. The reduction gear 16 is connected to the output shaft of the turbine engine 12 and is arranged axially with the turbine engine 12.

[0063] The second lubrication system 161 includes a second lubricating oil tank 161a and a second drive mechanism 161b, the second drive mechanism 161b including an electric motor, that is, the second lubrication system 161 is electrically driven, and therefore can have a smaller size.

[0064] For example, such as Figure 1 As shown, the second lubrication system 161 is located on the side of the turbine engine 12 away from the intake device 13, for example, below the turbine engine 12. For example, the second lubrication system 161 is arranged axially alongside the cleaning device 14, and the second lubrication system 16 is closer to the reduction gear 16 than the cleaning device 14, thereby facilitating the lubrication of the reduction gear 16 by the second lubrication system 16.

[0065] The interior of the anechoic chamber is a relatively enclosed space. The operation of the turbine engine 12 can easily lead to high temperatures or natural gas leaks inside the anechoic chamber. Furthermore, the danger is hidden, which can cause delays in the assessment of danger during manual inspections, and the safety of personnel and equipment cannot be reliably guaranteed.

[0066] For example, the power unit 1 also includes a fire protection system that can provide early warning of potential hazards inside the anechoic chamber. In at least one example, the fire protection system can automatically extinguish fires inside the anechoic chamber 11, greatly improving the reliability of equipment operation and the safety of personnel.

[0067] Figure 3A This is a schematic diagram of a fire protection system provided in at least some embodiments of this disclosure. For clarity, Figure 3A Some components of the fracturing equipment have been omitted.

[0068] like Figure 3AAs shown, the fire protection system 17 includes at least one fire detector 171 and a fire-fighting material generator 172 located in the anechoic chamber 11. The fire detector 171 may include, but is not limited to, temperature detectors, smoke detectors, flame detectors, combustible gas detectors, etc.; when there are multiple types of fire detectors, the number of each type of fire detector is not limited.

[0069] The fire-fighting material generator 172 contains fire-fighting materials. For example, the fire-fighting materials include aerosols. Compared with traditional dry powder materials, aerosols have better fire-extinguishing performance for the same volume. Therefore, the container of aerosol occupies less space, making it convenient to install in the anechoic chamber 11.

[0070] like Figure 3A As shown, the fire protection system 17 includes multiple fire detectors 171 installed on the roof of the anechoic chamber 11 to detect fires at multiple different locations within the anechoic chamber 11; for example, fire detectors 171 are respectively installed directly above the turbine engine 12 and the reduction gear 16. The multiple fire detectors 171 can be of the same or different types. A fire-fighting material generator 172 is installed on a support column 160 between the turbine engine 171 and the reduction gear 16.

[0071] For example, the fire protection system 17 also includes an alarm 173, a controller 174, a fire display 175, and an emergency switch 176 located outside the anechoic chamber 11. The controller 174 is connected to the alarm 173, the fire detector 171, and the fire-fighting material generator 172 via signals (e.g., communication). When the fire detector 171 detects an anomaly, such as detecting that at least one of the temperature, smoke concentration, or combustible gas concentration in the anechoic chamber 11 exceeds a threshold, or detecting a flame, it will trigger the controller 174 to automatically start the fire-fighting material generator 172 and spray fire-fighting materials, while simultaneously controlling the alarm 173 to issue an alarm signal.

[0072] For example, the fire protection system 17 may also include a manual fire extinguishing device 177 located outside the anechoic chamber 11 for on-site personnel to manually extinguish the fire. For example, the manual fire extinguishing device 177 may be a dry powder fire extinguisher.

[0073] Figure 3B Schematic diagrams of fire suppression systems in fracturing equipment provided for other examples of this disclosure. For example... Figure 3B As shown, the fire protection system includes a control unit, an alarm and a fire-fighting material generator, multiple temperature sensors, multiple smoke sensors, and multiple combustible gas sensors. The control unit is connected to the alarm, the temperature sensors of the fire-fighting material generator, the smoke sensors, and the combustible gas sensors, respectively.

[0074] For example, the control unit is configured to control the plurality of temperature sensors to simultaneously detect temperatures at different locations within the turbine engine nacelle, generate a temperature data set using the obtained temperature data, and periodically repeat the above operations and output the temperature data set, thereby detecting the temperature within the nacelle.

[0075] For example, the control unit is further configured to control the plurality of smoke detectors to simultaneously detect smoke at different locations within the turbine engine nacelle, generate a smoke data set using the obtained smoke data, and periodically repeat the above operations and output the smoke data set, thereby detecting the smoke within the nacelle.

[0076] For example, the control unit is further configured to control the plurality of flammable gas sensors to simultaneously detect the concentration of flammable gas at different locations within the turbine engine nacelle, generate a flammable gas data set using the obtained flammable gas concentration data, and periodically repeat the above operations and output the flammable gas data set, thereby detecting the flammable gas within the nacelle, for example, the flammable gas includes methane.

[0077] For example, the control unit is further configured to periodically call the temperature data set and the temperature threshold value for conditional judgment in response to a preset temperature threshold value, the judgment condition being whether more than half of the temperature data in the temperature data set is higher than the temperature threshold value, if the result is yes, outputting fire information, if the result is no, outputting alert information, wherein the alert information includes temperature data higher than the temperature threshold value and its detection location.

[0078] For example, the control unit is further configured to periodically call the smoke data set and the smoke threshold value for conditional judgment in response to an externally input smoke threshold value, the judgment condition being whether more than half of the smoke data in the smoke data set is higher than the smoke threshold value, if the result is yes, outputting fire information, if the result is no, outputting alert information, wherein the alert information includes smoke data higher than the smoke threshold value and its detection location.

[0079] For example, the control unit is further configured to periodically call the flammable gas data set and the flammable gas concentration threshold value for conditional judgment in response to an externally input flammable gas concentration threshold value, the judgment condition being whether more than half of the flammable gas concentration data in the flammable gas data set is higher than the flammable gas concentration threshold value, if the result is yes, outputting warning information, if the result is no, outputting alert information, wherein the alert information includes flammable gas concentration data higher than the flammable gas concentration threshold value and its measurement location.

[0080] For example, the control unit is further configured to trigger a fire-fighting material generator to perform fire-fighting operations, such as spraying aerosol, carbon dioxide, etc., in response to the fire information, and simultaneously trigger an alarm to emit an alarm signal, such as a sound signal and / or a light signal. For example, the fire-fighting material generator includes a spraying device, such as a nozzle, a liquid storage device, and a pipeline structure.

[0081] For example, the control unit is further configured to review the detection of the combustible gas to improve the accuracy of the detection. For example, the control unit is configured to determine whether the warning information is received at the same time in response to the fire information, and if the determination result is yes, no processing is performed, and if the determination result is no, an abnormal group is generated by calling all the methane concentration data whose methane concentration value is less than the methane concentration threshold value and the detection position thereof, and the abnormal group is output.

[0082] The fire-fighting system can review the combustible gas concentration sensor according to temperature sensor calibration and smoke sensor calibration, avoid equipment abnormalities, and further improve the fire-fighting safety performance of the equipment.

[0083] For example, as shown in Figure 1 The air inlet assembly 18 is located on one side of the soundproof cabin in the axial direction of the turbine engine, and the accommodation space of the soundproof cabin 12 is connected. The air outlet assembly 19 is located on the other side of the soundproof cabin in the axial direction of the turbine engine, and is arranged opposite to the air inlet assembly 19. The air outlet assembly 19 is connected with the accommodation space of the soundproof cabin 12. The air inlet assembly 18 and the air outlet assembly 19 are used to create a flowing environment in the soundproof cabin, which is helpful for heat dissipation in the cabin.

[0084] Figure 4A An enlarged schematic view of the air outlet assembly 19 is shown. For example, as shown in Figure 4A The air outlet assembly 19 includes an air outlet pipeline 191 and a guide-out portion 192 connected with the air outlet pipeline 191. The guide-out portion is used to change the orientation of the air outlet of the air outlet assembly, so as to effectively reduce the damage of wind sand from the air outlet assembly to the materials in the cabin.

[0085] For example, during the loading or transportation of the fracturing equipment, the air outlet assembly 19 is usually close to the front, i.e. the vehicle head, along the transportation direction; and the air inlet assembly 18 is closer to the rear, i.e. the vehicle tail, so as to facilitate the unloading and fracturing operation of the fracturing equipment after reaching the operation site. In this way, during the transportation process, wind sand is easy to flow into the soundproof cabin from the air outlet assembly 19.

[0086] As shown in Figure 4A By arranging the guide-out portion 192, the orientation of the air outlet is changed from horizontal to forward (i.e. the movement direction) to obliquely downward, so as to effectively reduce the inflow of wind sand. Figure 4AThe direction of the air outlet is shown by the dashed arrow. However, the disclosure is not limited to the direction of the air outlet of the air outlet assembly after the air outlet part is arranged. In other examples, the air outlet can be upward or to the side, and the disclosure is not limited thereto. For example, the air outlet part 192 and the air outlet pipe 191 can be rotatably connected, and the direction of the air outlet of the air outlet assembly 19 can be changed by rotating the air outlet part 192.

[0087] As shown in FIG. 1, for example, the air outlet part 192 is in the shape of an elbow, and the cross section is conical, for example, the conical angle is 40°-60°, for example, 45°. Figure 4A

[0088] For example, as shown in FIG. 1, the air outlet part 192 includes a shielding part 192a configured to shield the air outlet 191a of the air outlet pipe 191 to block external wind and sand, and an air outlet part 192b configured to discharge the gas flowing from the air outlet pipe 191 into the air outlet part 192. Figure 4A Figure 4A The boundary of the shielding part 192a and the air outlet part 192b is shown by the dashed line perpendicular to the air outlet 191a of the air outlet pipe 191, but the boundary actually does not necessarily exist.

[0089] For example, the orthogonal projection of the shielding part 192a on the plane where the air outlet 191a of the air outlet pipe 191 is located at least partially overlaps the air outlet 191a to form a shield, and the overlapping area is greater than 30% of the area of the air outlet to achieve effective shielding.

[0090] The air outlet part 192 is designed in structure to achieve the shielding effect autonomously, and such design does not require additional power or control.

[0091] In other examples, for example, as shown in FIG. 1, the air outlet part 192b can include a rotating shaft 193a and a blade 193b arranged on the rotating shaft 193a, and the blade 193b can rotate around the rotating shaft, for example, under the action of external force. For example, the rotating shaft and the blade are located at the air outlet of the air outlet part. By rotating the blade, the air outlet part can be opened and closed. For example, the air outlet part can be closed during transportation, and the air outlet part can be opened during fracturing operation. Figure 4B The schematic diagrams of the rotating shaft and the blade in the direction perpendicular to the air outlet surface of the air outlet part 192b are shown in FIG. 1, in which the air outlet part is in the closed state (left side) and the open state (right side), respectively. Figure 4B Figure 4B Figure 4B

[0092] ​​​​​For example, the power device further comprises an exhaust silencer which is communicated with the turbine engine 12 through an exhaust pipeline for silencing and guiding the exhaust gas discharged from the turbine engine 12 to the atmosphere. Figure 5A A structural schematic diagram of the exhaust silencer provided by at least one embodiment of the present disclosure is shown.

[0093] As shown in the drawings, Figure 5A The exhaust silencer 20 comprises an L-shaped gas transmission channel 201, which is L-shaped, has an air inlet 201a at one end thereof communicated with the turbine engine 12 through an exhaust pipeline for air intake, and has an upward air outlet 201b at the other end thereof for facilitating the exhaust gas generated by the turbine engine to be discharged to the atmosphere. Figure 5A The transmission direction of the gas is shown by arrows.

[0094] The exhaust silencer 20 further comprises a silencing layer 202 sleeved on the inner wall of the gas transmission channel 201 for silencing, which can effectively reduce the noise during the gas transmission when the gas in the gas transmission channel 201 contacts the silencing layer 202. For example, the silencing layer 202 comprises silencing cotton.

[0095] For example, the exhaust silencer 20 further comprises a silencing hole plate 203 located on the inner wall of the silencing layer 202, which is provided with holes for the gas in the gas transmission channel 201 to contact the silencing layer 202 so as to play a silencing role.

[0096] Figure 5B A structural schematic diagram of the silencing hole plate 203 is shown. For example, the silencing hole plate 203 is tubular, Figure 5B A partial schematic diagram of the silencing hole plate 203 is shown.

[0097] For example, the silencing hole plate 203 is provided with a plurality of silencing holes 203a arranged in an array, which can not only realize the full contact of the gas with the silencing hole plate, but also improve the silencing effect through the collision between the gas and the hole wall of the silencing hole plate 203. For example, the radius of the silencing hole 203a is 2-8 mm. The embodiments of the present disclosure do not limit the planar shape of the silencing hole, which can also be a long circular shape, an elliptical shape, a square shape, a diamond shape, etc.

[0098] For example, as shown in the drawings, Figure 5A The air inlet 201a of the exhaust silencer 20 has a retracted structure, the inner diameter of which gradually decreases along the air intake direction. When the exhaust gas enters the gas transmission channel 201, the space is contracted, so that the gas flow direction changes rapidly, thereby improving the silencing effect.

[0099] For example, as shown in the drawings, Figure 5AAs shown, the exhaust silencer 20 further comprises a heat insulation layer 204 between the inner wall of the exhaust silencer 20 and the sound insulation layer 202, so as to prevent the exhaust silencer shell from being scalded. For example, the exhaust gas discharged by the turbine engine has a temperature as high as 600℃, and thus needs to be insulated.

[0100] For example, the exhaust silencer 20 further comprises a drain 205 at the bottom. For example, when the exhaust silencer 20 is filled with water, the water can be drained through the sound hole plate 203, and finally drained from the drain 205.

[0101] Figure 5A As shown, the exhaust silencer 20 not only plays a sound insulation role, but also keeps the gas transmission pipeline as smooth as possible, thereby reducing the exhaust resistance and improving the exhaust efficiency.

[0102] Figure 5C A structural schematic diagram of an exhaust silencer provided for another embodiment of the present disclosure is shown. As shown, Figure 5C Unlike the embodiment shown, Figure 5A As shown, the exhaust silencer 20 comprises a sound insulation layer 206 for increasing the resistance of exhaust gas to achieve the function of sound insulation and noise reduction. For example, the sound insulation layer 206 comprises a heat-resistant material to have an adsorption function on noise, and the heat-resistant material is, for example, sound insulation cotton. For example, the sound insulation layer 206 is arranged in the branch of the gas transmission pipeline 201 close to the air outlet 201b, and the exhaust gas entering the pipeline reaches the air outlet 201b through the sound insulation layer 206.

[0103] For example, in some examples, the air outlet of the leading-out part 192 of the air outlet assembly 19 can be arranged to face the outer surface of the exhaust silencer 20, so as to perform surface cooling on the exhaust silencer by the gas discharged by the air outlet assembly 19, thereby achieving effective utilization of the exhaust gas.

[0104] As shown, Figure 1 As shown, the fracturing equipment 5 further comprises a fracturing pump device 2, and the fracturing pump device 2 comprises a fracturing pump 21, which is, for example, a plunger pump. The fracturing equipment 5 further comprises a transmission mechanism 3, and the transmission mechanism 3 comprises, for example, a shaft coupling. For example, the shaft coupling can be in the form of a flexible shaft coupling, a transmission shaft, a clutch, etc.

[0105] The fracturing pump device 2 is connected to the power device 1 through the transmission mechanism 3, and the power device 1 is configured to drive the fracturing pump 21 to perform fracturing operation. The turbine engine 12, the transmission mechanism 3 and the fracturing pump 21 are arranged in sequence along the axial direction of the turbine engine, for example, coaxially arranged, thereby improving the transmission efficiency.

[0106] Figure 6 A schematic diagram of a fracturing equipment provided for at least one embodiment of the present disclosure is shown. As shown, Figure 6As shown, the turbine engine, the speed reduction mechanism, the transmission mechanism, and the fracturing pump are arranged in sequence along the axial direction of the turbine engine, for example, coaxially, so as to improve the transmission efficiency.

[0107] For example, the fracturing device can further comprise a brake mechanism arranged between the turbine engine and the fracturing pump, so as to realize power cut-off between the fracturing pump and the turbine engine. For example, when the turbine engine starts to start, the speed is not large enough, and the brake mechanism can be started to prevent the fracturing pump from being driven to affect the fracturing effect. For example, the brake mechanism can comprise brake pads, brake calipers, etc.

[0108] As shown, Figure 6 The brake mechanism can be arranged at any one or more of the following positions: between the turbine engine and the speed reduction mechanism (position A), between the speed reduction mechanism and the transmission mechanism (position B), and between the transmission mechanism and the fracturing pump (position C), so as to finally realize the disconnection between the power input and the power output. For example, as shown, Figure 1 The brake mechanism 21 can be located between the speed reduction mechanism 16 and the transmission mechanism 3 or integrated into the speed reduction mechanism 16, so that the overall structure is more compact.

[0109] As shown, Figure 1 The fracturing pump device 2 further comprises a third lubrication system 22 for lubricating the fracturing pump 21. The third lubrication system 22 comprises a motor 221 and is located on the side of the transmission mechanism 3 away from the air inlet device 13. The third lubrication system 22 further comprises a lubricating oil tank 222.

[0110] For example, as shown, Figure 1 The third lubrication system 22 is located below the transmission mechanism 3, so as to save space.

[0111] For example, as shown, Figure 1 The fracturing pump device 2 further comprises a lubricating oil heat dissipation device 23 for dissipating heat from the third lubrication system 22. The lubricating oil heat dissipation device 23 is located above the fracturing pump 21, i.e. on the side of the fracturing pump 21 away from the base of the fracturing pump 21. For example, the lubricating oil heat dissipation device 23 comprises a motor 231 and a radiator 232.

[0112] The lubricating oil system 23 and the fracturing pump 21 are arranged in the longitudinal direction, so as to make the structure more compact.

[0113] For example, the fracturing pump device 2 further comprises a fracturing pump base 24 located below the fracturing pump 21, i.e. on the side away from the air inlet device 13, for elevating the fracturing pump 21, so that the fracturing pump 21 and the turbine engine 12 are arranged in a straight line along the axial direction of the turbine engine 12, thereby improving the transmission efficiency.

[0114] For example, as shown in Figure 1 The fracturing equipment 5 further comprises a skid 6, and the power device 1 and the pump device 2 are installed on the skid 6 to be fixed.

[0115] In the example shown in Figure 1 The fracturing equipment 5 is a skid-mounted equipment. However, embodiments of the present disclosure are not limited thereto. In other examples, the fracturing equipment 5 can also be a truck-mounted equipment or a semi-trailer-mounted equipment.

[0116] Figure 7A A schematic diagram of a fracturing equipment provided by another embodiment of the present disclosure is shown in Figure 7A The power device 1 further comprises a power skid 51, and the soundproof cabin 11 is installed on the power skid 51 to be fixed; the pump device 2 further comprises a pump skid 52, and the pump skid 52 has a bearing surface 523, and the fracturing pump 21 is installed on the bearing surface 523 of the pump skid 52 to be fixed. The power skid 51 and the pump skid 52 are respectively provided with control circuits and circuit wires for the power device 1 and the pump device 2, etc.

[0117] Embodiments of the present disclosure are not limited to the form of the power skid and the pump skid. For example, the power skid / pump skid can only comprise a bottom structure, or can comprise a bottom structure and a cage structure extending upwardly to further fix the devices installed on the bottom structure.

[0118] For example, the power skid 51 and the pump skid 52 are detachably connected to facilitate transportation. Embodiments of the present disclosure are not limited to the connection mode of the power skid 51 and the pump skid 52. For example, the power skid 51 and the pump skid 52 can be connected by a buckle, a connecting plate, etc.

[0119] For example, the power skid 51 and the pump skid 52 can be connected by an ear plate, one of the power skid 51 and the pump skid 52 has a single ear plate, and the other has a double ear plate, and the two are connected by a pin shaft.

[0120] Figure 7B A perspective view of the connection between the power skid and the pump skid is shown in Figure 7C A top view of the connection is shown. As shown in Figure 7B The power skid 51 has a single ear plate 510, and the pump skid 52 has a double ear plate 520. The single ear plate 510 is inserted into the double ear plate 520, the pin hole of the two is aligned, and a pin shaft 530 is inserted into the pin hole to connect the power skid and the pump skid.

[0121] For example, the fracturing equipment 5 can further comprise an integral skid 53, and the power skid 51 and the pump skid 52 are respectively installed on the integral skid 53 to be fixed. For example, the power skid 51 and the pump skid 52 are respectively detachably connected to the integral skid 53 to facilitate transportation.

[0122] Figure 8A-8B A schematic diagram of a fracturing device is provided for yet some embodiments of the present disclosure. Unlike the embodiments shown in the above figures, the power skid 51 comprises a tiltable mechanism 54 for tilting to a horizontal state to place the pump skid 52. For example, the pump skid 52 is detachably connected with the tiltable mechanism 54, when the fracturing device is to be transported, the pump skid 52 can be detached, and the tiltable mechanism 54 is retracted; after reaching the work site, the tiltable mechanism 54 is tilted horizontally, and the pump skid 52 is installed on the tiltable mechanism 54. Figure 7A Figure 8A Figure 8B Schematic diagrams of the tiltable mechanism of the fracturing device in the retracted state and the working state are shown respectively. For example, the muffling cabin and the turbine engine can be integrated in the power skid 51, and the fracturing pump can be integrated in the pump skid. For example, the tiltable mechanism 54 can also serve to elevate the pump skid 52, so that the fracturing pump and the turbine engine are arranged linearly along the axial direction of the turbine engine, thereby improving the transmission efficiency.

[0123] In at least one example, the turbine engine in the fracturing device is driven by fuel (for example, natural gas), and other auxiliary power systems (for example, various lubricating systems, cooling systems, cleaning devices, starting devices, brake mechanisms, deceleration mechanisms, heat dissipation devices, and power for the gas path system) are all driven by electricity, so that the fracturing device can have the advantages of high driving efficiency, compact structure, small size, and environmental protection, and can reduce the power supply pressure of the fracturing work site.
