Description

Technical Field

[0001] The utility model relates to the technical field of power supply, in particular to a mobile power station. Background Art

[0002] At present, power stations are widely used in outdoor construction occasions. They are generally powered by hydraulic oil and are used in mining, road maintenance, building construction, floor construction and other fields. They mainly include components such as engines, generators, hydraulic pumps, etc. These components are simply connected in parallel to output power to the outside. In this way, each power output component works independently and occupies a large volume, which is not conducive to movement and use in complex terrain environments. In addition, due to the large number of independent connecting pipes and connecting devices of each component, the failure rate is high. It is even difficult to locate the point of failure inside the bloated device, which is very unfavorable for stable outdoor use. In addition, the existing power stations commonly provide power supply for external output. The power station itself is often unable to move or carry the actuator to perform actions. The way to move or carry the actuator is often an additional independent power system, which makes the power station more bloated and bulky.

[0003] The Chinese utility model patent (patent number: 202121738890.8) discloses a traveling power station, including a chassis and a carriage, in which a cooling device, an engine, a transfer case, a hydraulic pump group, and a tank support frame are arranged in sequence along the length direction of the chassis in the carriage; the hydraulic pump group includes a main pump and a fan pump; a hydraulic oil tank is arranged on the tank support frame, a mode switching valve is arranged under the tank support frame, and an oil supply port is arranged on the mode switching valve; a battery pack and a control system are arranged on the side of the engine; the engine, the transfer case, and the hydraulic pump group are connected in sequence, the main pump is connected to the mode switching valve, and the fan pump is connected to the cooling device; the battery pack is connected to the control system, and the control system is connected to the engine and the mode switching valve.

[0004] It can be seen that the traveling power station disclosed in the patent can provide traveling power for the drilling rig. Each component is independently configured, and additional auxiliary devices are required to cooperate with the hydraulic pump, such as a fan pump and a cooling device for cooling. The resulting pipe connection redundancy is relatively serious, resulting in its large size and high failure rate. In addition, its power sources are independent of each other and affect each other, making it difficult to work together, resulting in low external power output efficiency of the power station.

DETAILED DESCRIPTION

[0025] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0026] like Figure 1-4 A mobile power station is shown, comprising a vehicle body 1 and an engine 2, an air pump 3, an oil pump 4, a generator 5 and a battery 6 respectively installed on the vehicle body 1, the engine 2 having a start-stop motor for starting and stopping itself and a rotating shaft 21 for outputting rotational power, the output end of the battery 6 is electrically connected to the start-stop motor to supply power to the start-stop motor, the rotating shaft 21 is respectively connected to the input shaft of the generator 5 and the input shaft of the oil pump 4, the power output end of the generator 5 is connected to the input end of the battery 6; the hydraulic oil output end of the oil pump 4 is connected to the power input end of the air pump 3; the hydraulic oil output end of the oil pump 4, the air pressure output end of the air pump 3, and the power output end of the generator 5 are respectively connected to corresponding power interfaces 7 for providing power internally and externally.

[0027] like Figure 4As shown, the kinetic energy generated by the engine 2 is converted into electric power obtained by the generator 5 and hydraulic power obtained by the oil pump 4, respectively. The electric energy stored in the battery 6 can also react to provide start-stop power for the engine 2, and the air pump 3 is driven to work by the oil pump 4 to obtain pneumatic power. As a result, the various components work together, which greatly reduces connection redundancy and energy loss, thereby effectively improving the power output efficiency. Moreover, the various components working together reduce the use of connecting components and make the structure more reasonable and compact, thereby making the mobile power station smaller and lighter, suitable for flexible transfer and transportation, and better applicable in different working environments. In addition, since the engine 2 is the source of energy output, the subsequent component work can be checked based on this, and fault detection and judgment are simpler. Combined with the internal and external power output of each power source component, the power station can operate efficiently and stably in indoor and outdoor fields such as road maintenance, building construction, and floor construction.

[0028] The air pump 3 is a hydraulic air compressor driven by high-pressure hydraulic oil, and the battery 6 is a 12V, 24AH lead-acid battery 6, which can supply power to the start-stop motor of the engine 2 to achieve temporary start-stop of the engine 2. Of course, the battery 6 can also provide direct current power to the outside.

[0029] When the engine 2 is started, the rotational power generated by it is output through the rotating shaft 21, and the rotating shaft 21 can transmit the rotational power to the input shaft of the generator 5 and the input shaft of the oil pump 4 respectively, so that the generator 5 and the oil pump 4 are started and powered respectively, and the hydraulic oil power generated by the oil pump 4 is then sent to the air pump 3 to power the air pump 3. Thus, the power generated by the air pump 3, the oil pump 4, the generator 5, and the battery 6 can be provided to the inside and outside of the mobile power station respectively. Various powers can be used inside and outside at the same time or in a time-sharing manner.

[0030] In one embodiment, the rotating shaft 21 is divided into a first output part and a second output part after being connected by a transmission mechanism, the first output part is connected to the input shaft of the oil pump 4 by transmission, and the second output part is connected to the input shaft of the generator 5 by transmission. The transmission mechanism can be a belt transmission mechanism, a gear transmission mechanism, a connecting rod transmission mechanism, etc., to achieve a one-to-two rotational power output, thereby dividing the rotational power of the engine 2 into two. In this case, the generator 5 and the oil pump 4 can be simultaneously input with rotational power and keep working at the same time. Of course, a valve body or a clutch can also be set at the input end of the generator 5 and the oil pump 4 to achieve timely use and reduce loss. Through configuration, the transmission mechanism can realize power distribution, so that the power output by the rotating shaft 21 of the engine 2 can be reasonably distributed.

[0031] As a preferred embodiment, the transmission mechanism is an electromagnetic clutch 8 arranged on the rotating shaft 21, the active component of the electromagnetic clutch 8 is connected to the rotating shaft 21, and the rotating shaft 21 is provided with a first pulley 9 used as a first output part, and the first pulley 9 is connected to the input shaft of the oil pump 4 via a transmission belt; the driven component of the electromagnetic clutch 8 is coupled to the active component of the electromagnetic clutch 8, and the driven component of the electromagnetic clutch 8 is installed with a second pulley 10 used as a second output part, and the second pulley 10 is connected to the input shaft of the generator 5 via a transmission belt. When it is necessary to provide hydraulic power internally or externally, the start-up of the engine 2 will directly drive the oil pump 4 to work to output hydraulic power. At this time, if the battery 6 is fully charged and there is no other internal or external power supply demand, the second output part stops rotating, which can avoid redundant work of the generator 5 and further improve the power utilization rate. In situations where power supply is needed, the second output part is controlled by the electromagnetic signal and the clutch action of the electromagnetic clutch 8 to make the second output part rotate synchronously with the first output part, so that the generator 5 can work at the same time to output electric power. Therefore, the power output of the rotating shaft 21 is configured by the electromagnetic clutch 8 to select the distribution of power according to the actual working conditions.

[0032] Of course, in one embodiment, each power source itself can use an independent controller or transmission or distributor to achieve selective power distribution output, thereby making the power output more flexible and more adaptable.

[0033] In order to further improve the working stability of the mobile power station, the mobile power station also includes a heat dissipation system 11 installed on the vehicle body 1. The engine 2, the generator 5, the air pump 3 and the oil pump 4 are arranged in a straight line on the vehicle body 1, and the heat dissipation system 11 is located at the common rear side of the engine 2, the generator 5, the air pump 3 and the oil pump 4. The heat dissipation system 11 provides heat dissipation for each power source component, and also provides heat dissipation for the connecting components between the power source components, and makes fuller use of the position of the heat dissipation system 11 to provide heat dissipation capacity at the same time, so as to compress the volume and reduce the weight of the mobile power station.

[0034] Specifically, the heat dissipation system 11 of this embodiment includes a heat dissipation fan 111 and a cooling box 112. The cooling box 112 is arranged on the rear side of the vehicle body 1, and the heat dissipation fan 111 is located in front of the cooling box 112. In this way, the heat dissipation fan 111 will be between the power source and the cooling box 112, and can transfer the heat energy transferred from the power source and the cooling box 112 to the surrounding air and dissipate it to the outside, which effectively improves the heat dissipation efficiency of the power source and the cooling box 112 while saving space. Furthermore, the hydraulic oil output by the oil pump 4 flows through the cooling box 112 and is cooled and then flows back to the oil pump 4, so that the hydraulic oil can be cooled and refluxed with a more compact and reasonable structure.

[0035] As a preferred embodiment, in this embodiment, the vehicle body 1 is a support structure, so as to have both a firm and light effect, wherein the engine 2, the air pump 3, the oil pump 4, the generator 5 and the battery 6 are respectively installed at the bottom of the vehicle body 1 and located inside the support structure to protect each power source and reduce the exposed parts. The front and rear sides of the vehicle body 1 are respectively provided with a mounting structure 12 for mounting the execution components. The mounting structure 12 can mount the execution components, and the power output by each power source can be provided to the execution components in time to realize the diversification of the execution components and wider applicability. The execution components can be nozzles, paving heads, scraping rakes, buckets, etc., or storage cylinders for raw materials required for construction, raw material mixing devices, etc. These execution components can obtain the hydraulic power, pneumatic power, and electric power provided by the mobile power station in time when performing actions. The choice of the mounting structure 12 can be a detachable plug-in structure, a snap-on structure, a magnetic suction structure, a hook structure, etc., or a reserved installation part formed integrally or separately with the vehicle body 1, and the execution components are mounted by detachable fasteners.

[0036] In order to further reasonably optimize the space usage of the vehicle body 1 and reduce the volume of the vehicle body 1, the power interface 7 connected to the oil pump 4 of this embodiment includes a first valve group 71 and a second valve group 72 connected via an oil circuit, the first valve group 71 is arranged at the front side of the vehicle body 1, and the second valve group 72 is arranged at the rear side of the vehicle body 1; the power interface 7 connected to the air pump 3 includes a third valve group and a fourth valve group connected via an air circuit, the third valve group is arranged at the front side of the vehicle body 1, and the fourth valve group is arranged at the rear side of the vehicle body 1. Providing corresponding valve groups at corresponding positions can enable the hydraulic oil and high-pressure gas power to be refluxed after timely corresponding control at the actuator, thereby reducing redundant connections of the oil circuit and the air circuit.

[0037] like Figure 3 , Figure 5 As shown, in one embodiment, in order to make more effective use of the installation space on the vehicle body 1, the power interface 7 connected to the generator 5 of this embodiment includes a control box 73 arranged on the upper rear side of the vehicle body 1, and the control box 73 includes components such as switches and electrical sockets to control the power supply internally and externally. A driving seat 17 and a control platform 18 are respectively provided on the vehicle body 1 in front of the control box 73, and the output end of the battery 6 is electrically connected to the control platform 18, so as to further make full and reasonable use of the electric power and the space on the vehicle body 1.

[0038] To further increase flexibility, Figure 5As shown, the actuator of this embodiment includes a first mobile bracket 13 respectively located on the front side of the vehicle body 1, the first mobile bracket 13 is mounted on the corresponding mounting structure 12, and a first top cylinder 15 is provided on the bracket structure on the front side of the vehicle body 1. The power output rod of the first top cylinder 15 is hinged with the first mobile bracket 13, and the power interface 7 connected to the oil pump 4 is connected to the hydraulic oil inlet end of the first top cylinder 15. The first mobile bracket 13 of this embodiment is a transverse mobile bracket driven by a gear rack, which is powered by a generator 5, so that a small actuator can also be displaced in the transverse direction, and can be more suitable for occasions of construction over a large area. Of course, according to the needs of use, the first mobile bracket 13 can also be configured as a vertical mobile bracket. The first top cylinder 15 drives the first mobile bracket 13 to switch between the states of tilting and returning to the center, which increases the degree of freedom of the actuator to execute the action without increasing the additional space occupation, thereby enhancing the flexibility of the use of this mobile power station.

[0039] Likewise, if Figure 5 As shown, the actuator of this embodiment includes a second mobile bracket 14 respectively located at the rear side of the vehicle body 1, and the second mobile bracket 14 is mounted on the corresponding mounting structure 12. A second top cylinder 16 is provided on the bracket structure at the rear side of the vehicle body 1. The power output rod of the second top cylinder 16 is hinged with the second mobile bracket 14, and the power interface 7 connected to the oil pump 4 is connected to the hydraulic oil inlet end of the second top cylinder 16. The second mobile bracket 14 of this embodiment is a lifting bracket driven by a fixed pulley lifting belt, which is powered by a generator 5, so that a small actuator can also be displaced in the vertical direction, and can better adapt to large-scale construction occasions in the height direction. Of course, according to the needs of use, the second mobile bracket 14 can also be configured as a horizontal mobile bracket. The second top cylinder 16 drives the second mobile bracket 14 to switch between the tilting and returning states, which increases the degree of freedom of the actuator to execute the action without increasing the additional space occupation, thereby enhancing the flexibility of the use of this mobile power station.

[0040] Of course, components such as funnels, nozzles, scrapers, grippers, and cylinders may be added to the first movable bracket 13 and the second movable bracket 14 to optimize the complete functions achieved by the execution components.

[0041] The implementation methods of the present invention are not limited to these. According to the above-mentioned embodiments of the present invention, by using conventional technical knowledge and customary means in the field, without departing from the above-mentioned basic technical ideas of the present invention and without conflict, the above-mentioned preferred embodiments may also be modified, replaced or combined in various other forms, and the other embodiments obtained all fall within the scope of protection of the present invention.
