Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0019] It should be noted that in the description of this utility model, the terms "horizontal", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] like Figure 1-5 As shown, this utility model provides a high-efficiency integrated power system for special equipment, which is installed inside the special equipment. It includes a base assembly 5, and a water tank assembly, an engine group 1, a transfer case 3 and a pump group 4 arranged sequentially and at intervals along the length of the base assembly 5. Other areas of the base assembly 5 also integrate a fuel tank assembly, a urea tank assembly, an exhaust aftertreatment device 16 and a control box 7. The fuel tank assembly is connected to the engine group 1 and is used to supply fuel to the engine group 1; the control box 7 is connected to the engine group 1 and is used to control the operation of the engine group 1; the engine group 1 is also connected to the pump group 4 through the transfer case 3, and the transfer case 3 is used to distribute the power of the engine group 1 to the pump group 4; the exhaust aftertreatment device 16 is connected to the engine group 1; the urea tank assembly is connected to the exhaust aftertreatment device 16; the water tank assembly is connected to the engine group 1 and is used to supply coolant to the engine group 1.

[0021] In the above technical solution, the water tank assembly, engine unit 1, transfer case 3, and pump unit 4 are arranged sequentially along the length of the base assembly 5. The fuel tank assembly, urea tank assembly, exhaust gas aftertreatment device 16, and control box 7 are integrated in other positions of the base assembly 5. The structure is compact and can effectively improve the spatial layout of the power system of special equipment, making the power system a compact, small-sized, and functionally concentrated power unit. This reduces the space occupied by the power system installed inside the special equipment, improves space utilization, avoids the problem of redundancy in the overall size of the special equipment, and ultimately achieves adaptation to the narrow well site space. It also facilitates centralized maintenance and repair of the power system area by maintenance personnel without affecting the normal operation of each piece of equipment.

[0022] The fuel tank assembly stores fuel, and the urea tank assembly stores urea solution. During operation, the fuel tank assembly supplies fuel to engine unit 1, and the control box 7 controls the start of engine unit 1. Engine unit 1 burns fuel to generate mechanical energy, which is then transferred to transfer case 3. Transfer case 3 has one input port and multiple output ports. The input port connects to engine unit 1, and the multiple output ports are connected to pump groups 4, such as the injection head pump, roller pump, and integrated pump, via splined holes.

[0023] In another technical solution, the base assembly 5 includes a power base skid 28 and various brackets. The power base skid 28 is mounted on the inner bottom surface of the special equipment and includes two parallel spaced channel beams 35. The top surfaces of the two channel beams 35 are connected as a whole by two parallel spaced rectangular tubes 40. The two ends of the two channel beams 35 are also detachably connected to two movable beams 34 respectively. The fuel tank assembly is placed in the space enclosed by the two channel beams 35, the two movable beams 34 and the two rectangular tubes 40. The water tank assembly, engine unit 1, transfer case 3, pump unit 4, urea tank assembly and control box 7 are mounted on the power base skid 28 by various brackets.

[0024] In this technical solution, such as Figure 4 As shown, the power base skid 28 consists of two channel beams 35 and a rectangular tube 40 welded to the top surface of the channel beams 35. The structure is simple. The movable beams 34 at the ends of the channel beams 35 are used to improve the load-bearing capacity of the base assembly 5. The fuel tank assembly is placed in the space enclosed by the two channel beams 35, the two movable beams 34 and the two rectangular tubes 40, which has a high space utilization rate. The movable beams 34 are detachably mounted on the channel beams 35 by bolts. When maintenance personnel need to repair the fuel tank assembly, they can remove the movable beams 34 and take the fuel tank assembly out from the bottom of the power base skid 28 for convenient maintenance.

[0025] In another technical solution, the fuel tank assembly includes: The fuel tank 29 has a flat rectangular structure. The outer side wall of the fuel tank 29 is provided with an inspection port 38, a level gauge 37, a handle 36, and two sets of quick connectors 39. The level gauge 37 and the handle 36 are located on the side wall of the fuel tank 29 near the movable beam 34. The inspection port 38 is located on the top surface of the fuel tank 29. The fuel tank 29 is connected to the water tank assembly and the engine assembly 1 respectively through the two pairs of quick connectors. Multiple mounting bases 18 are fixedly mounted on the outer peripheral sidewall of the fuel tank 29, and the mounting bases 18 are used to fix the fuel tank 29 to the inner bottom surface of the special equipment.

[0026] In this technical solution, such as Figure 5As shown, the fuel tank 29 is made of corrosion-resistant alloy material, and a handle 36 is welded to the outer wall, which allows maintenance personnel to easily pull the fuel tank 29 out from the bottom of the power base skid. A level gauge 37 can be installed at the center of the side of the fuel tank 29 in the width direction using fasteners, allowing for easy observation of the fuel level. An inspection port 38 is located at the center of the top of the fuel tank 29, providing a space for internal maintenance. Two quick connectors 39 are used to connect the water tank assembly and the engine assembly 1, respectively, to connect the water tank assembly to the fuel tank 29, enabling... The fuel cooling circulation and the connection between the fuel tank 29 and the engine unit 1 provide fuel to the engine unit 1; the fuel tank 29 adopts a flat design, which compresses the height dimension to the greatest extent while ensuring that the volume of the fuel tank 29 remains unchanged, so as to achieve high integration and realize efficient integration of the power system; the mounting base 18 is set in the shape of horseshoe, and there are four of them, which are fixed on both sides of the width direction of the fuel tank 29. One end of the mounting base 18 is welded to the fuel tank 29, and the other end needs to be connected to the inner bottom surface of the special equipment by fasteners to achieve overall fixation of the fuel tank 29.

[0027] In another technical solution, the two rectangular tubes 40 are respectively located in the middle and one end of the channel beam 35, and the engine group 1 includes an engine 14, an engine bracket 15 and an air filter 17. The engine 14 is fixedly mounted on the two rectangular tubes 40 and connected to the transfer case 3.

The engine 14 is provided with an intake pipe 11 connected to the air filter 17, an exhaust pipe 12 connected to the exhaust aftertreatment device 16, and an intake pipe 24, an exhaust pipe 25, a water inlet pipe 27, and a drain pipe 26 connected to the water tank assembly. The engine is also connected to the corresponding quick connectors on the fuel tank 29 through a fuel supply pipe and a fuel return pipe.

[0028] In the above technical solution, the engine 14 is mounted on the rectangular tube 40. The rectangular tube 40 elevates the engine, preventing positional interference between the engine assembly and the fuel tank 29 during installation. The engine is a key component providing a continuous power source for the efficient integrated power system. The engine 14 has a rated power of 460kW and a maximum torque of 3000N.m. This type of engine exhibits extremely high stability and adaptability in its performance indicators, providing a stable power source for special equipment under harsh conditions, such as... Figure 1 , Figure 2As shown, the engine bracket 15 is mounted on the top of the engine 14 with fasteners. The engine bracket 15 has two threaded connection holes. One threaded connection hole is connected to the front of the engine 14 with fasteners, and the other threaded connection hole is connected to the rear of the engine 14 with fasteners. During installation, ensure that the upper plane of the engine bracket 15 is level with the upper plane of the engine, thereby ensuring the horizontal installation of the exhaust aftertreatment device 16 and the air filter 17. The exhaust aftertreatment device 16 and the air filter 17 are fixed to the engine bracket 15 with fasteners. During engine operation, a large amount of air is drawn in. If the air is not filtered, suspended dust in the air will be drawn into the engine cylinders, accelerating the wear of the piston assembly and cylinders. Therefore, the air intake of engine 14 is connected to air filter 17 through intake pipe 11. Air enters the engine after being filtered through air filter 17. The engine exhaust gas is discharged into exhaust aftertreatment device 16 through exhaust pipe 12. The engine has a water circulation system and an air circulation system. The water circulation system is connected to the water tank assembly through water inlet pipe 27 and drain pipe 26 to establish a circulating water passage for cooling the engine coolant. The air circulation system is connected to the water tank assembly through intake pipe 24 and exhaust pipe 25 to establish a circulating air passage for cooling the engine exhaust gas. Engine 14 is connected to fuel tank 29 through fuel supply pipe and fuel return pipe. Fuel tank 29 supplies fuel to the engine through fuel supply pipe. Unburned excess fuel in the engine flows back into fuel tank 29 through fuel return pipe, forming a fuel supply cycle.

[0029] One end of exhaust pipe 25 is connected to the engine exhaust outlet, and the other end is connected to the exhaust cooling inlet on the water tank assembly. One end of intake pipe 24 is connected to the exhaust cooling outlet on the water tank assembly, and the other end is connected to the engine exhaust inlet, thus realizing engine exhaust cooling circulation. One end of drain pipe 26 is connected to the engine drain outlet, and the other end is connected to the water cooling inlet on the water tank assembly. The water inlet pipe 27 is connected to the water cooling outlet on the water tank assembly, and the other end is connected to the engine drain inlet, thus realizing engine water cooling circulation. All the above connecting pipes are installed and fixed by spring clamps.

[0030] In another technical solution, the engine oil filter 10 assembly is mounted on the power base skid and located outside the engine. The oil inlet of the oil filter 10 assembly is connected to the oil outlet of the engine oil pump through an oil inlet pipe, and the oil outlet of the oil filter 10 assembly is connected to the oil passage inlet of the engine through an oil outlet pipe.

[0031] In this technical solution, due to the limited space in the high-efficiency integrated power system, the engine oil filter 10 is moved out of the engine body to facilitate the replacement of the oil filter 10.

[0032] In another technical solution, the water tank assembly includes a water tank body 2, which is connected to the exhaust pipe 25, intake pipe 24, drain pipe 26 and water inlet pipe 27 on the side facing the engine. A fuel cooler 19 is installed on the top of the water tank body 2, which is connected to the fuel tank 29 and is used to cool the fuel in the fuel tank 29. A blower fan 20 is also installed on the side of the water tank body 2 near the engine, which is coaxially connected to the engine through a coupling. The engine drives the blower fan 20 to rotate through the coupling to blow air and dissipate heat from the water tank body 2.

[0033] In the above technical solution, the fuel cooler 19 is provided with two fuel line ports, which are connected to the fuel tank 29 via fuel lines, thus forming a passage between the fuel tank 29 and the fuel cooler 19 to achieve fuel cooling circulation; Figure 3 As shown, the water tank body 2 adopts a blower-type heat dissipation design. When the engine starts, the coupling drives the blower-type fan 20 to rotate, thereby achieving blower-type heat dissipation of the water tank body 2.

[0034] In another technical solution, support rods 8 are symmetrically arranged on both sides of the water tank body 2. One end of any support rod 8 is fixedly mounted on the power base skid 28, and the other end is fixedly mounted on the water tank body 2. The support rod 8 is a telescopic structure.

[0035] In this technical solution, the support rod 8 is provided with ear plates at both ends. One end is fixed to the ear plate of the water tank body 2 by fasteners, and the other end is fixed to the ear plate of the power base skid 28 by fasteners.

[0036] In another technical solution, a fuel pump 9 is also installed on the power base skid 28. The fuel pump 9 is connected to the fuel tank 29 through a fuel pipe and is used to supply fuel to the fuel tank 29.

[0037] In this technical solution, the fuel pump 9 is mainly used to refuel the fuel tank 29. The fuel pump 9 is fixed to the power base skid by fasteners. The fuel pump 9 is equipped with a fuel pipe interface and is connected to the fuel pipe. The end of the fuel pipe is connected to the fuel filler port of the fuel tank 29. This avoids manual refueling and effectively reduces labor intensity.

[0038] In another technical solution, an elastic rubber pad is attached to the bottom of the fuel tank 29; the interior of the fuel tank 29 is divided into multiple fuel chambers by an oil separator, and adjacent fuel chambers are interconnected.

[0039] In this technical solution, since the engine is installed above the fuel tank 29, an elastic rubber pad is set at the bottom of the fuel tank 29 to avoid the engine from resonating with the fuel tank 29 during operation; the fuel tank 29 has a large internal volume, and an oil separator is set inside the fuel tank 29 to eliminate the damage caused by fuel vibration during transportation.

[0040] In another technical solution, an air tank 13 is also installed on the power base skid 28, which is used to provide air power for special equipment.
