Description

Technical Field

[0001] The present application relates to the technical field of hybrid power stations, and in particular to a heat balancing device for a hybrid power station. Background Art

[0002] Our company has developed a variety of electric-drive engineering equipment, such as the drill pipe electric gripper (Announcement No. CN220285688U) and the electric-drive crawler system (CN217804992U). These replace the original hydraulic drive with an electric drive, offering advantages such as high precision and excellent maneuverability. However, to conserve energy, these equipment typically utilize a drag-line external power supply, connecting the equipment to the commercial power grid, which then supplies power to the horizontal directional drilling rig via the national grid. However, power outages can occur in some areas of the national grid. To ensure smooth project progress, our company has added a hybrid power station to our electric-drive equipment. Our current hybrid power station consists of a diesel generator set, a battery pack, and a motor. The diesel generator set charges the battery pack, which then outputs stable electrical energy. Furthermore, the motor can directly generate mechanical energy.

[0003] Regarding the above-mentioned related technologies, the inventors found that the heat generated by the diesel generator after long-term operation will affect the energy storage effect and power output stability of the energy storage battery pack, thereby leading to a decrease in the normal function and reliability of the hybrid power station.

[0016] As a preferred solution of the present application, the heat dissipation assembly includes an axial flow heat dissipation fan arranged on the box body.

[0017] To implement the above technical solution, external cold air is blown into the box through an axial flow cooling fan, thereby reducing the temperature of the energy storage battery pack.

[0031] The following is combined with Figure 1-4 This application is described in further detail.

[0032] The embodiment of the present application discloses a heat balance device for a hybrid power station. Figure 1 The heat balance device for the hybrid power station includes a box body 1, in which a diesel generator set 2, an energy storage battery pack 3 and a motor 4 are arranged; the box body 1 is provided with a power generation cooling mechanism 6 for dissipating heat and cooling the diesel generator set 2 and a temperature control component 7 for controlling the temperature of the energy storage battery pack 3.

[0033] Because the diesel generator set 2 vibrates violently when working, its direct installation and fixation in the box body 1 will cause the box body 1 and components such as the energy storage battery pack 3 and the motor 4 inside the box body 1 to vibrate, which will cause the internal components of each component to be damaged due to vibration after long-term use. Therefore, a shock absorber 5 is provided between the diesel generator set 2 and the box body 1. The shock absorber 5 in this embodiment is a shock-absorbing rubber gasket, which reduces the occurrence of damage to various components due to vibration.

[0034] The power generation cooling mechanism 6 includes a cooling water tank 61 connected to the diesel generator set 2, and a cooling assembly for cooling the cooling water tank 61. That is, after the cooling water in the cooling water tank 61 is cooled by the cooling assembly, the cold water (coolant) in the cooling water tank 61 is used to cool the diesel generator set 2, thereby preventing the excessive internal temperature of the diesel generator set 2 from being transmitted to the energy storage battery pack 3 on the side. The cooling assembly includes a cooling mounting frame 62. The cooling water tank 61 is fixed to the cooling frame. A hood 63 is fixedly mounted on the cooling frame via a mounting bracket. The hood 63 is mounted on the cooling frame, so that the cooling water tank 61 installed in the cooling frame is also covered by the hood 63. The hood 63 is provided with a plurality of first fans 64. That is, the first fans 64 blow all the external cold air through the hood 63 into the cooling water tank 61, thereby reducing the temperature of the cooling water in the cooling water tank 61. At the same time, in order to prevent the cold air blown in from becoming hot and gathering in the box body 1 to cause the temperature to rise, a number of upward-flipping inspection doors 11 are provided on the side walls of the box body 1, and an exhaust grille 12 is provided on the inspection door 11, that is, the internal hot air flow can be discharged from the exhaust grille 12, that is, the hot air flow is discharged to both sides, so as to reduce the occurrence of poor heat dissipation effect caused by the backflow of hot air flow.

[0035] The cooling water tank 61 comprises a first water tank 611 and a second water tank 612. The first water tank 611 is connected to the exhaust system of the diesel generator set 2, allowing the cooling water in the first water tank 611 to lower the exhaust temperature and thus reduce nitrogen oxide emissions. The second water tank 612 is connected to the cylinder block of the diesel generator set 2 and is used to cool the cylinder block of the diesel generator set 2 to prevent overheating. A third water tank 613 is located below the second water tank 612. This third water tank 613 cools the remaining components of the generator set 4 that require cooling, thereby ensuring the temperature stability of the diesel generator set 2.

[0036] At the same time, in order to prevent the hot air blown into the box body 1 by the first fan 64 from entering the battery pack assembly, causing the energy storage battery pack 3 to heat up, an insulation plate 8 is provided between the diesel generator set 2 and the energy storage battery pack 3, that is, the box body is divided into two independent spaces by the insulation plate 8, and the diesel generator set 2 and the energy storage battery pack 3 are respectively arranged in the two spaces, thereby preventing the hot air generated by the diesel generator set 2 from blowing into the energy storage battery pack 3.

[0037] The temperature control component 7 includes a heating component 71 and a heat dissipation component, that is, the energy storage battery pack 3 is heated by the heating component 71 to ensure the charging efficiency and energy storage efficiency of the energy storage battery pack 3 in the cold winter season. At the same time, the heat dissipation component can cool the energy storage battery pack 3 to prevent the battery pack temperature from being too high.

[0038] The heat dissipation component is configured as a liquid cooling mechanism or an air cooling mechanism, and in this application it is an air cooling mechanism, which includes an axial flow fan arranged on the box body 1.

[0039] The heating assembly 71 includes a heating fan (not shown) positioned on the side of the battery pack. This fan heats the battery pack to maintain a constant temperature. The heating fan is connected to the exhaust pipe of the diesel generator set 2 via a pipe, allowing the high-temperature exhaust gas to be used to preheat the battery pack.

[0040] The implementation principle of a heat balance device for a hybrid power station in an embodiment of the present application is as follows: after the cooling water in the cooling water tank 61 is cooled by the cooling component, the diesel generator set 2 is cooled by the cold water (coolant) in the cooling water tank 61, thereby preventing the internal temperature of the diesel generator set 2 from being too high and being transmitted to the energy storage battery pack 3 on the side; the energy storage battery pack 3 is heated by the heating component 71 to ensure the charging efficiency and energy storage efficiency of the energy storage battery pack 3 in the cold winter season, and at the same time, the heat dissipation component can cool the energy storage battery pack 3 to prevent the energy storage battery pack 3 from being too high in temperature, which may lead to a decrease in the normal function and reliability of the hybrid power station.

[0041] 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.
