[0034] The following is combined with Figure 1 -Attached Figure 11 This application is described in further detail.

[0035] The embodiment of the present application discloses a power integration box. Figures 1-4 The power integration box includes an integration box 2 for installing a power source 1 of a pressure working machine 23, and the pressure working machine is a high-load working machine;

[0036] Reference Figure 4 , both ends of the integrated box 2 are provided with doors 3 for opening and closing the integrated box 2, and there are two doors 3 on one side and the hinge axis is along the vertical direction;

[0037] Refer to Figures 5 and Figure 6 , a receiving plate 4 is provided in the integrated box 2 and near the bottom, and the receiving plate 4 is fixedly provided on the side wall of the integrated box 2. The power source 1 of the pressure working machine 23 is installed on the receiving plate 4. A water injection cavity 5 is formed between the receiving plate 4 and the bottom of the integrated box 2. The water injection cavity 5 contains cooling water. A plurality of through holes 6 are provided on the receiving plate 4. The through holes 6 are arranged in a rectangular array along the surface of the receiving plate 4. After the cooling water is injected into the water injection cavity 5, the cooling water evaporates naturally. The evaporation of the cooling water absorbs the heat in the integrated box 2, and the cooling water The temperature in the integrated box 2 is lowered. At the same time, when the cooling water evaporates naturally, the water vapor generated passes through the receiving plate 4 through the through hole 6 and reaches the power source 1, thereby cooling the power source 1. At the same time, after the water vapor enters the integrated box 2, the heat in the integrated box 2 is transferred to the water droplets, and then removed from the integrated box 2 through air convection, thereby accelerating the rapid drop in the ambient temperature in the integrated box 2. At the same time, when the water vapor adheres to the power source 1, the convection air accelerates the evaporation rate of the water vapor, further cooling the power source 1.

[0038] Reference Figure 6 and Figure 7After the door 3 is opened, the mounting frame 7 is rotated so that the mounting frame 7 is in the position of the door 3, and then the fan 8 is started. The fan 8 on one side draws air from the environment into the integrated box 2. The air entering the integrated box 2 cools down the power source 1 and the ambient temperature. The fan 8 on the other side draws air from the integrated box 2 and discharges it from the integrated box 2. Under the action of the fan 8, the air flow efficiency in the integrated box 2 is accelerated, and the cooling effect of the integrated box 2 is improved. At the same time, the residence time of the hot air in the integrated box 2 is shortened, and the possibility of temperature increase in the integrated box 2 is reduced.

[0039] Reference Figure 5 、 Figure 6 and Figure 8 In the embodiment of the present application, an air duct 9 is provided in the integrated box 2 and in the water injection chamber 5. One end of the air duct 9 is closed and the other end is connected to an air compressor 10. The air compressor 10 is located above the receiving plate 4. A plurality of air outlets 11 are provided on the air duct 9. The air outlets 11 are evenly opened along the axial direction of the air duct 9. The air duct 9 is located above the cooling water and the air outlet 11 is immersed in the cooling water. The air compressor 10 injects air into the air duct 9 and discharges it through the air outlet 11; when the power source 1 is working, the air compressor 10 is started, and the air compressor 10 compresses the hot air in the integrated box 2. The compressed air is passed into the air duct 9 and discharged from the air outlet 11. The air after passing through the air outlet 11 enters the cooling water. On the one hand, the cooling water cools the air, and the cooled air enters the integrated box 2 through the through hole 6, thereby cooling the power source 1 and the ambient temperature. On the other hand, the evaporation of the cooling water is accelerated and the cooling water is stirred, so that the cooling water is quickly cooled to cool the power source 1 and the ambient temperature of the integrated box 2.

[0040] Reference Figure 7 and Figure 9In the implementation of this application, in order to further improve the cooling effect of the environment in the integrated box 2, a mounting ring 12 and a plurality of mounting rods 13 are provided in the mounting frame 7. One end of the mounting rod 13 is used to fix the mounting ring 12, and the other end is set in the inner frame of the mounting frame 7. The fan 8 is set in the mounting ring 12. An adjustment part is provided on the mounting ring 12. The adjustment part is used to adjust the direction of the fan 8 so that the air inlet and outlet ends of the fan 8 are swapped; after the fans 8 on both sides are started, the fan 8 on one side presses the outside air into the integrated box 2, and the fan 8 on the other side discharges the air in the integrated box 2. In the above process, the air entering the integrated box 2 is difficult to hit the air in the middle and away from the air inlet fan 8. The power source 1 is cooled down because the air entering the integrated box 2 is at a lower temperature. The heat in the integrated box 2 is quickly transferred to the air, causing the temperature of the air to gradually increase during the air flow, and the cooling effect of the air to gradually decrease. Therefore, when the fan 8 is cooling down, the adjustment part acts on the fan 8 to swap the air inlet and outlet ends of the fan 8. The fan 8 on the side with the higher temperature draws outside air into the integrated box 2, and the fan 8 on the other side moves the air out of the integrated box 2. Under the above process, the temperature in the integrated box 2 is more balanced, and the possibility of a higher temperature on one side is reduced, further improving the cooling effect on the power source 1 and the inside of the integrated box 2.

[0041] Reference Figure 7 and Figure 9 In the embodiment of the present application, the adjustment member includes a mounting shaft 14 and a first motor 15. Two mounting shafts 14 are provided and are respectively located on both sides of the fan 8 casing. The mounting shaft 14 is rotatably provided on the mounting ring 12. The first motor 15 is used to drive the mounting shaft 14 to rotate and drive the fan 8 to rotate. The fan 8 is powered by a battery. When the air inlet direction of the fan 8 is adjusted, the first motor 15 is started. The first motor 15 drives the mounting shaft 14 to rotate. The rotation of the mounting shaft 14 drives the fan 8 casing to rotate 180 degrees. The operation is simple and convenient. At the same time, the fan 8 casing can be driven by the first motor 15 to rotate at any angle, so that the fan 8 is directed toward the power source 1 with a higher temperature, thereby improving the cooling effect of the power source 1.

[0042] In the embodiment of the present application, four mounting rods 13 are provided and are evenly arranged along the circumference of the mounting ring 12. The mounting rods 13 correspond one-to-one to the border of the mounting frame 7 and are slidably provided on the border of the mounting frame 7. The mounting rods 13 slide along the length direction of the border of the mounting frame 7. The mounting rods 13 are a retractable structure. Because the power sources 1 in the integrated box 2 are highly concentrated, the gaps between the power sources 1 are small. For example, the fan 8 is in a single position, which easily causes the power source 1 to hinder the flow of air, thereby affecting the convection of the air. Therefore, in the embodiment of the present application, by sliding the mounting rods 13, the other mounting rods 13 adaptively retract and change the position of the mounting ring 12, and adjust the direction of air inflow, which facilitates the flow of air in the integrated box 2 and improves the cooling effect on the power source 1.

[0043] Reference Figure 7 and Figure 9 In the implementation of this application, the mounting rod 13 includes a multi-stage sleeve tube 131 that is mutually sleeved. The sleeve tube 131 at the head end is slidably set on the edge of the mounting frame 7. The sleeve tube 131 at the end is used to fix the mounting ring 12. The mounting rod 13 also includes an electric push rod 132. The length direction of the output shaft of the electric push rod 132 is parallel to the length direction of the sleeve tube 131. The body of the electric push rod 132 is fixedly set on the sleeve tube 131, and the output shaft is fixedly set on the adjacent sleeve tube 131. The electric push rod 132 is used to adjust the length of the mounting rod 13 and adjust the position of the mounting ring 12. ; When adjusting the position of the mounting ring 12, first start the electric push rod 132 on the opposite side, the electric push rod 132 on one side extends, and the electric push rod 132 on the other side retracts, driving the mounting ring 12 to move in the length direction of the output shaft of the electric push rod 132, and then start the electric push rods 132 on the other two sides to adjust the mounting ring 12 to the required position. The operation is simple and convenient. In addition, the electric push rod 132 is integratedly controlled by the controller to make the mounting ring 12 reciprocate in the mounting frame 7 (such as reciprocating up and down, reciprocating left and right, and moving in a rectangular path), further improving the cooling effect of the power source 1.

[0044] Reference Figure 7 and Figure 10 In the embodiment of the present application, the replaceable parts of the electric push rod 132 are a screw 16 and a second motor 17. The screw 16 and the second motor 17 are rotatably set on the frame of the mounting frame 7. There are two screws 16 and they are located on adjacent frames. The length directions of the two screws 16 are perpendicular to each other. The mounting rod 13 is threadedly connected to the screw 16. The second motor 17 is used to drive the screw 16 to rotate and drive the mounting rod 13 to move to adjust the position of the mounting ring 12; when adjusting the position of the mounting ring 12, start the two second motors 17, and the second motor 17 drives the mounting rod 13 to move. In this process, the mounting rod 13 moves to adaptively adjust the length, and the position adjustment of the mounting ring 12 is simple and convenient to operate.

[0045] Reference Figure 7 and Figure 11 By adjusting the direction of the air inlet and outlet ends of the fan 8, the power sources 1 at both ends of the integrated box 2 have a better cooling effect. However, the power source 1 located in the middle is affected by the warm air, and the temperature of the power source 1 is higher. Therefore, in the embodiment of the present application, a ventilation hole 18 is opened at the top of the integrated box 2 and located at the center line; the middle part has a higher air temperature, which causes the gas to expand, and the warm gas flows toward the top of the integrated box 2, and then is discharged from the integrated box 2 through the ventilation hole 18, so that the temperature in the middle of the integrated box 2 is reduced, and the power source 1 is at the optimal working temperature.

[0046] Reference Figure 7 and Figure 11 The top of the integrated box 2 is provided with a cover, which is used to block the ventilation hole 18 when the ventilation hole 18 is ventilated. The cover includes a sunshade cloth 19 arranged on the top of the integrated box 2. The sunshade cloth 19 is long and has an edge of the sunshade cloth 19 parallel to the length direction of the integrated box 2. One side is fixed to the top of the integrated box 2 and the other side is rolled up on the top of the integrated box 2. A reel 20 for rewinding the sunshade cloth 19 is provided on the top of the integrated box 2 for rotation. A vortex spring is sleeved on the reel 20, which is used to drive the reel 20 to have a rotation tendency, thereby rewinding the sunshade cloth 19; a door frame 21 and a third motor 22 are provided on the top of the integrated box 2 for rotation. The mounting shaft 14 of the door frame 21 is located in the middle of the integrated box 2 and on the axis of the ventilation hole 18. The third motor 22 is used to drive the door frame 21 to rotate and lift the sunshade cloth 19, so that the sunshade cloth 19 is triangular and erected on the top of the integrated box 2; the function of the sunshade cloth 19 The third motor 22 is started, and the third motor 22 drives the door frame 21 to rotate 90 degrees, so that the door frame 21 is perpendicular to the top of the integrated box 2. When the door frame 21 rotates, the cross bar of the door frame 21 lifts the sunshade cloth 19, so that the sunshade cloth 19 is erected in a triangular shape on the top of the integrated box 2, and the warm air in the middle of the integrated box 2 is discharged through the ventilation hole 18, and under the action of convection air, the air under the sunshade cloth 19 is discharged; further, after the sunshade cloth 19 is erected, a slope is formed on the top of the integrated box 2 to avoid direct sunlight on the top of the integrated box 2, reducing the possibility of rapid temperature increase inside the integrated box 2 due to sunlight; at the same time, when the sunshade cloth 19 is quickly lifted, negative pressure is formed at the bottom of the sunshade cloth 19 to extract the hot air in the integrated box 2, and the hot air is discharged from the top of the integrated box 2.

[0047] The implementation principle of a power integration box in the embodiment of the present application is as follows:

[0048] When the pressure working machine 23 is working, the equipment in the integrated box 2 provides the power source 1 for the pressure working machine 23. When the power source 1 is working, the box doors 3 on both sides are opened to form air convection on both sides of the integrated box 2, which is convenient for cooling the inside of the integrated box 2, so that the power equipment is at a friendly temperature, thereby making the power equipment in the best working condition; when the power equipment is working, cooling water is injected into the water injection cavity 5, and the cooling water evaporates naturally. The evaporation of the cooling water absorbs the heat in the integrated box 2, and the temperature in the integrated box 2 is reduced. At the same time, when the cooling water evaporates naturally, the water vapor generated passes through the through hole 6. The receiving plate 4 reaches the power source 1, and cools the power source 1; at the same time, the fans 8 on both sides are started, and the fan 8 on one side draws air from the environment into the integrated box 2. The air entering the integrated box 2 cools the power source 1 and the ambient temperature. The fan 8 on the other side draws air from the integrated box 2 and discharges it from the integrated box 2. Under the action of the fan 8, the air flow efficiency in the integrated box 2 is accelerated, and the cooling effect of the integrated box 2 is improved; at the same time, the residence time of hot air in the integrated box 2 is shortened, and the possibility of temperature increase in the integrated box 2 is reduced.

[0049] The embodiment of the present application discloses a high-load belt pressure working machine, which uses a power integration box as a power source 1 to drive the belt pressure working machine 23 to operate.

[0050] The implementation principle of a high-load pressure working machine in the embodiment of the present application is as follows:

[0051] Connect the oil pipe of the pressure working machine 23 to the corresponding power source 1. At the same time, cool the integrated box 2 so that the power source 1 is at a better working temperature when the pressure working machine 23 is working.

[0052] The high-load pressure-carrying operation machine 23 in this application can perform hydraulic well repair and complete high-pressure operations. It has two types: conventional lift base and offshore construction translation base. It is not only suitable for onshore construction, but also for different offshore platform construction. It is capable of operating in hydrogen sulfide environments, with an operating temperature between -35°C and 50°C. The more advanced turntable system makes drilling and grinding operations more efficient.

[0053] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
