Description

Technical Field

[0001] Embodiments of the present invention relate to the technical field of stacked power generation devices, and more particularly, to a stackable power generation device. Background Art

[0002] A generator set is a power supply device that uses a generator, with diesel or natural gas as fuel, and an engine as the power support to drive the generator to generate electricity. For the requirements of convenient transportation, rapid installation, and protection, the generator set can be installed in a container and sold as a containerized generator set. During transportation, containerized generator sets usually adopt a stacked transportation method to save space. However, in the prior art, containerized generator sets usually use the connectors of ordinary containers for stacked connection. For a heavy-load device like a containerized generator set, stacking is more difficult.

[0003] In some places with extremely high requirements for power continuity, such as hospitals, data centers, and financial institutions, and places with extremely high requirements for high-power output, such as large factories and offshore platforms, multiple generator sets are usually equipped. The heavy generator sets of existing equipment are usually horizontally arranged, occupying a large area. Although containerized generators can be used in a stacked manner, during the operation of the generator set, vibrations will occur. Coupled with the different vibration frequencies of the two stacked containerized generator sets, the load on the connectors between the two containers is extremely large and requires maintenance or replacement. Summary of the Invention

[0004] To overcome the above defects, the present invention provides a stackable power generation device, which solves the technical problem that the connection parts of stacked containerized generators have a large load due to vibrations in the prior art.

[0005] According to one aspect, at least one embodiment of the present invention provides a stackable power generation device, including a plurality of stacked containerized generator sets, and further including: A support frame, spaced on one side of the containerized generator set; A first rotating frame, rotatably arranged on the support frame, and the first rotating frame has a first chute; A second rotating frame, rotatably and slidably arranged on the top of the lower containerized generator set, the rotation axis of the second rotating frame is parallel to the rotation axis of the first rotating frame, and the second rotating frame has a second chute; A support seat, one end of the first rotating frame far from the rotation axis and one end of the second rotating frame far from the rotation axis are both hinged to the bottom of the support seat, and the support seat is used to support the upper containerized generator set; A connecting shaft, parallel to the rotation axis of the first rotating frame, the connecting shaft penetrates through the first sliding groove and the second sliding groove, and the connecting shaft can slide along the first sliding groove and the second sliding groove to approach or move away from the rotation axis of the first rotating frame or the hinge point between the second rotating frame and the support base; A first damper, one end is arranged on the top of the lower container-type generator set, and the other end is arranged on the connecting shaft, and the first damper is used to support the connecting shaft.

[0006] For example, in a stackable power generation device provided by at least one embodiment of the present invention, the first damper supports the connecting shaft in the vertical direction, and further includes: A sliding seat, slidably arranged on the top of the lower container-type generator set, the second rotating frame is rotatably arranged on the sliding seat, and the sliding seat can slide close to or away from the support frame, so that the rotation axis of the second rotating frame approaches or moves away from the rotation axis of the first rotating frame.

[0007] For example, in a stackable power generation device provided by at least one embodiment of the present invention, it further includes: A fixing plate, arranged on the top of the lower container-type generator set, and the fixing plate is located on the sliding path of the sliding seat; A second damper, with both ends acting on the fixing plate and the sliding seat respectively, and the second damper is used to provide resistance for the sliding of the sliding seat.

[0008] For example, in a stackable power generation device provided by at least one embodiment of the present invention, the rotation axis of the first rotating frame is parallel to the main axis of the rotor in the container-type generator set.

[0009] For example, in a stackable power generation device provided by at least one embodiment of the present invention, the container-type generator set includes: A box body, used to hold the generator set, the support base is used to support the box body located on the upper layer, the sliding seat is slidably arranged on the top of the box body located on the lower layer, and the outside of the box body has a guiding groove that penetrates up and down, and the projection of the guiding groove in the vertical direction is T-shaped; A connecting rod, one end is arranged on the outside of the box body, and the connecting rod and the guiding groove are located on opposite sides of the box body; A guiding block, arranged at the other end of the connecting rod, and the projection of the connecting rod and the guiding block in the vertical direction is T-shaped and adapted to the guiding groove. The guiding block is configured such that after the guiding block of one box body enters the guiding groove of another box body, the guiding block rises and falls along the guiding groove; A cushion block is arranged outside the box body and on the same side of the box body as the guide groove. The cushion block is used to abut against the outside of the adjacent box body so that when the guide block moves up and down along the guide groove, the adjacent box bodies will not directly collide with each other.

[0010] For example, in a stackable power generation device provided by at least one embodiment of the present invention, the containerized generator set further includes: A ladder is arranged on the inner wall of the guide groove. The ladder is composed of a plurality of stepping rods. The plurality of stepping rods are spaced along the height direction of the guide groove on one side wall of the guide groove and have a clearance for the connecting rod to pass through between the other opposite side wall of the guide groove.

[0011] For example, in a stackable power generation device provided by at least one embodiment of the present invention, the bottom of the guide block is on the same horizontal line as the bottom of the box body, and the bottom of the guide groove is in a flared shape so that the guide block of one box body can horizontally slide into the guide groove of another box body.

[0012] For example, in a stackable power generation device provided by at least one embodiment of the present invention, the edge of the top of the guide block has a guide inclined surface, and the guide inclined surface is adapted to the flared shape of the bottom of the guide groove so that the guide block can smoothly enter the guide groove.

[0013] For example, in a stackable power generation device provided by at least one embodiment of the present invention, it further includes: A transition plate is arranged on the side of the support seat. There is a clearance between the bottom of the transition plate and the top of the lower box body, and the clearance is smaller than the height of the guide block. The transition plate has a transition sliding groove whose projection in the vertical direction is the same as that of the guide groove so that the guide block can partially enter the transition sliding groove before completely leaving the guide groove.

[0014] For example, in a stackable power generation device provided by at least one embodiment of the present invention, it further includes: There are two side baffles, which are arranged at intervals on the top of the support seat. The height of the side baffles is higher than the height of the guide block. The two side baffles are respectively used to abut against the two sides of the box body so that the box body slides along the length direction of the side baffles; A clamping plate is arranged on the top of the support seat. The sum of the height of the clamping plate and the height of the guide block is smaller than the height of the side baffle so that when the upper box body slides horizontally relative to the lower box body, it abuts against the two side baffles. The clamping plate has a clamping groove for placing the connecting rod, and both sides of the clamping plate abut against the side of the guide block and the box body that are close to each other respectively.

[0015] The beneficial effects of the embodiments of the present invention are as follows: In the present invention, through the first rotating frame and the second rotating frame, the vibration generated by the operation of the container-type generator set can be converted into the rotation of the first rotating frame and the second rotating frame. Combining with the connecting shaft passing through the first sliding groove and the second sliding groove, and the first damper supporting the connecting shaft in the vertical direction, when the height of the support seat changes due to the vibration generated by the operation of the container-type generator set, the sliding seat slides to keep the connecting shaft always in the same vertical plane, which is convenient for the first damper to weaken the vertical vibration. For the horizontal vibration of the container-type generator set, the sliding seat has a sliding tendency. Through the limiting effect of the first sliding groove and the second sliding groove on the connecting shaft, the horizontal vibration can be changed into the acting force on the connecting shaft, so that the first damper plays a role.

[0016] The arrangement mode of the first damper only needs to arrange several along the axis direction of the connecting shaft to generate damping effect on the vertical and horizontal vibrations of the container-type generator set. Compared with directly using the first damper to support the support seat, it can not only play the damping role in two directions, but also, on the basis of ensuring the horizontality of the support seat, only arrange at the same interval on a straight line, which simplifies the installation steps.

Detailed implementation manners

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention.

[0020] For the sake of simplicity of the drawings, only the parts related to the invention are schematically shown in each drawing, and they do not represent the actual structure of the product. In addition, for the sake of simplicity and easy understanding of the drawings, in some drawings, components with the same structure or function are only schematically shown for one of them, or only one of them is marked. In this article, "one" not only means "only this one", but also means "more than one" situation, and "several" includes "two" and "more than two".

[0021] In this article, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0022] In the present invention, unless otherwise clearly specified and defined, the first feature being "above" or "below" the second feature may include the direct contact of the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features between them.

The first feature being "below", "below", and "under" the second feature includes that the first feature is directly below and obliquely below the second feature, or only means that the first feature has a lower horizontal height than the second feature.

[0023] In the description of this embodiment, the orientation or positional relationship terms such as "upper", "lower", "left", and "right" are based on the orientation or positional relationship shown in the drawings. They are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention.

[0024] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0025] For the convenience of description, the direction of the rotor axis for power generation in the containerized generator set 100 is defined as the longitudinal direction, and the radial direction parallel to the ground is defined as the transverse direction. That is, the long side of the generator set 100 in the figure is the longitudinal direction, and the short side is the transverse direction.

[0026] As Figures 1 to 6 shown, it shows a superimposable power generation device in an embodiment of the present invention, which is composed of several superimposed containerized generator sets 100 and a supporting connection structure. The containerized generator set 100 serves as the main power generation body and is arranged in a stacked form, effectively saving space. The supporting connection structure includes a support frame 200, a first rotating frame 300, a second rotating frame 400, a support seat 510, a connecting shaft 600, and a first damper 700. These components work together to solve the problem of large loads at the connection parts due to vibration of the stacked containerized generator sets 100. The top of the support seat 510 can be connected to the upper box-type generator set through fasteners. The sliding seat 800 can slide on the top of the lower containerized generator set 100 to change the distance between the rotation axes of the second rotating frame 400 and the first rotating frame 300.

[0027] The support frame 200 and the lowermost containerized generator set 100 are fixed on the same cast-in-place ground by bolt fasteners, and several of them are distributed at intervals along the length direction of the containerized generator set 100. A first rotating frame 300 is rotatably arranged on each support frame 200. One end of the first rotating frame 300 is rotatably arranged on the support frame 200, and the rotation axis is horizontal and parallel to the long side of the containerized generator set 100. The end of the first rotating frame 300 far from the axis is hinged to the bottom of the support seat 510 to provide rotational support for the support seat 510. A first chute 310 is machined along the length direction of the first rotating frame 300. The cross-sectional shape of the first chute 310 is rectangular, and the size of the first chute 310 is adapted to the diameter of the connecting shaft 600 to ensure that the connecting shaft 600 can only slide along the first chute 310. The number of the second rotating frames 400 is the same as that of the first rotating frames 300. One end of the second rotating frame 400 is rotatably arranged on the top of the lower-layer containerized generator set 100, and the rotation axis is parallel to the rotation axis of the first rotating frame 300. The end of the second rotating frame 400 far from the axis is also hinged to the bottom of the support seat 510 to jointly support the upper-layer containerized generator set 100 with the first rotating frame 300. The first rotating frame 300 and the second rotating frame 400 are distributed in a cross shape. The synchronous rotation of the first rotating frame 300 and the second rotating frame 400 can change the height of the support seat 510. The connecting shaft 600 passes through the first chute 310 and the second chute 410, which is equivalent to making the intersection points of different first rotating frames 300 and second rotating frames 400 at the same height, ensuring the levelness of the support seat 510 and thus ensuring the stability of the upper-layer containerized generator set 100.

[0028] The first damper 700 is selected as a hydraulic damper and is composed of a cylinder barrel, a piston, a piston rod, a damping medium, a support spring, etc. One end of the cylinder barrel is fixed to the top of the lower-layer containerized generator set 100 by bolts or welding, and one end of the piston rod is connected to the connecting shaft 600. The damping medium is selected as high-viscosity hydraulic oil, which can effectively consume vibration energy. The damping coefficient of the first damper 700 is selected according to the vibration characteristics and load requirements of the generator set. The support spring in the first damper 700 mainly plays a supporting role. The support spring is compressed or extended by vibration, and the damping medium absorbs and consumes the energy transmitted by the generator set vibration to the support spring by generating damping on the piston. When the upper-layer generator set vibrates, the connecting shaft 600 will move accordingly. The first damper 700 uses the viscous resistance of the damping medium through the movement of the piston rod in the cylinder barrel to convert the vibration energy into heat energy and dissipate it, thereby reducing the impact of vibration on the connecting part and reducing the load on the connecting part.

[0029] Working principle: When the stackable power generation device is operating normally, the weight of the upper containerized generator set 100 is evenly transmitted to the first rotating frame 300 and the second rotating frame 400 through the support base 510, and then transmitted by them to the support frame 200 and the top of the lower containerized generator set 100. At this time, the first damper 700 provides a supporting force for the first rotating frame 300 and the second rotating frame 400 through the connecting shaft 600, so that the first rotating frame 300, the second rotating frame 400 and the connecting shaft 600 are in a relatively stable state. When the upper containerized generator set 100 and the lower containerized generator set 100 vibrate due to operation, the vibration is transmitted to the first rotating frame 300 and the second rotating frame 400 through the support base 510. The first rotating frame 300 and the second rotating frame 400 will rotate around their respective rotation axes, and the sliding seat 800 slides in the direction close to or away from the support frame 200, so that the connecting shaft 600 slides in the first chute 310 and the second chute 410, and makes a lifting movement relative to the lower containerized generator set 100. During the sliding process of the connecting shaft 600, the piston rod of the first damper 700 will move with the connecting shaft 600, generating a relative displacement in the cylinder barrel. Due to the viscous resistance of the damping medium, the damper will consume the vibration energy and convert it into heat energy, thereby suppressing the movement of the connecting shaft 600 and reducing the impact of the vibration on the connecting part. When the vibration weakens, the damping force of the first damper 700 makes the connecting shaft 600 gradually return to the initial position, and the first rotating frame 300 and the second rotating frame 400 also return to the relatively stable state accordingly. The entire connection structure is again in a state of stably supporting the upper generator set, waiting for the next possible vibration.

[0030] Through the first rotating frame 300 and the second rotating frame 400, the vibration generated by the operation of the containerized generator set 100 can be converted into the rotation of the first rotating frame 300 and the second rotating frame 400. Combining with the connecting shaft 600 passing through the first chute 310 and the second chute 410, and the first damper 700 supporting the connecting shaft 600 in the vertical direction, when the vibration generated by the operation of the containerized generator set 100 causes the height of the support base 510 to change, the sliding seat 800 slides to make the connecting shaft 600 always located in the same vertical plane, which is convenient for the first damper 700 to weaken the vertical vibration. For the horizontal vibration of the containerized generator set 100, the sliding seat 800 has a sliding tendency. Through the limiting effect of the first chute 310 and the second chute 410 on the connecting shaft 600, the horizontal vibration can be changed into a force acting on the connecting shaft 600, so that the first damper 700 can play a role.

[0031] The arrangement of the first dampers 700 only requires arranging several along the axial direction of the connecting shaft 600 to damp the vibrations of the containerized generator set 100 in the vertical and horizontal directions. Compared with directly using the first dampers 700 to support the support seat 510, it can not only provide damping in two directions, but also, on the basis of ensuring the horizontality of the support seat 510, be arranged at the same spacing in a straight line, simplifying the installation steps.

[0032] In some examples, the first dampers 700 support the connecting shaft 600 in the vertical direction, and it further includes a fixing plate 110 which is arranged on the top of the lower containerized generator set 100 and is located on the sliding path of the sliding seat 800; both ends of the second dampers 900 are respectively connected to the fixing plate 110 and the sliding seat 800 to provide resistance for the sliding of the sliding seat 800.

[0033] The fixing plate 110 provides a fixed connection point for the second dampers 900 and at the same time serves as a limiting reference structure for the sliding of the sliding seat 800. It cooperates with the second dampers 900 to limit the sliding speed and displacement of the sliding seat 800, thereby reducing the vibration of the containerized generator set along the sliding direction of the sliding seat 800. The second dampers 900 provide controllable resistance for the sliding of the sliding seat 800, buffer the sliding of the sliding seat 800 caused by vibration, and share the supporting force on the upper containerized generator set 100 with the first dampers 700.

[0034] The arrangement of the first dampers 700 and the second dampers 900 can not only share the acting forces with each other, but also, when the first dampers 700 or the second dampers 900 fail, both the first dampers 700 and the second dampers 900 can individually play the role of damping in two opposite directions.

[0035] In some examples, the rotation axis of the first rotating frame 300 is parallel to the main axis of the containerized generator set 100.

[0036] Since the vibration of the containerized generator set 100 is mainly generated by the cam between the piston cylinder and the main shaft, and the vibration direction is mainly in the plane perpendicular to the main axis of the containerized generator set 100, so arranging the rotation axis of the first rotating frame 300 parallel to the main shaft direction of the containerized generator set 100 can enable the first dampers 700 or the second dampers 900 to play the role of reducing vibrations in two directions in the same plane.

[0037] In some examples, the containerized generator set 100 is composed of a box body 120, a connecting rod 141, a guide block 142, and a cushion block 150. The box body 120 serves as the outer shell of the containerized generator set 100 and can effectively protect the generator set equipment inside. A vertically penetrating guide groove 130 is provided on the outer side of the box body 120, and the projection of the guide groove 130 in the vertical direction is T-shaped. The width and depth of the guide groove 130 are matched with the sizes of the guide block 142 and the connecting rod 141 to ensure that the guide block 142 can be firmly embedded in the guide groove 130. The length of the guide groove 130 penetrates the upper and lower ends of the box body 120, improving the convenience when two box bodies 120 are stacked. The connecting rod 141 serves as a bridge connecting the guide block 142 and the box body 120, connecting the guide block 142 and the box body 120 together, so that the guide block 142 can move along with the movement of the box body 120. And the connecting rod 141 and the guide block 142 cooperate to form a shape adapted to the guide groove 130.

[0038] The cushion block 150 is made of a material with good cushioning performance and wear resistance. The cushion block 150 plays a role of buffering and isolating between adjacent box bodies 120. When the guide block 142 moves up and down along the guide groove 130, the cushion block 150 can prevent direct collision between adjacent box bodies 120, reducing the noise and damage risk caused by collision.

[0039] Working principle: The operator first fixes the lower box body 120 on the ground, and then the operator uses a transporter on the ground to move the upper box body 120, so that the guide block 142 enters the guide groove 130. Then, a hoisting device is used to hoist the upper box body 120. Through the limiting effect of the guide groove 130 on the guide block 142, the stability and convenience of the box body 120 during hoisting can be improved, avoiding problems such as difficult positioning of the hoisting device and easy occurrence of collision.

[0040] In some examples, the containerized generator set 100 further includes a ladder 160. The ladder 160, as a part of the containerized generator set 100, is arranged on the inner wall of the guide groove 130, providing a convenient climbing passage for the operator. The ladder 160 is composed of several stepping rods 161. The stepping rods 161 are fixed on the inner wall of one side of the guide groove 130 in the form of a cantilever beam, forming an avoidance gap between the stepping rods 161 and the other side wall. The width of the avoidance gap is adapted to the diameter or width of the connecting rod 141 to ensure that the connection can pass through.

[0041] The main function of the ladder 160 is to provide a safe and convenient climbing passage for the operators, facilitating the operators to perform daily maintenance, repair on the containerized generator set 100 and operate the internal equipment. When the boxes 120 are stacked, the design of the avoidance gap ensures that the connecting rod 141 can pass through smoothly without affecting the normal cooperation between the guide block 142 and the guide groove 130, guaranteeing the stability of the connection structure between the boxes 120. At the same time, the setting of the ladder 160 does not occupy the external space of the box 120, making the layout of the entire power generation device more compact and reasonable.

[0042] In some examples, the bottom of the guide block 142 is on the same horizontal line as the bottom of the box 120. In this way, when the boxes 120 are stacked, the limiting effect of the guide block 142 and the guide groove 130 can act until the height of the upper box 120 exceeds the height of the lower box 120, ensuring the stability of the upper box 120 during the lifting process.

[0043] In some examples, a guide inclined surface 1421 is provided at the edge of the top of the guide block 142, and the guide inclined surface 1421 is adapted to the flared shape at the bottom of the guide groove 130, further optimizing the process of the guide block 142 entering the guide groove 130.

[0044] Working principle: When stacking two boxes 120, first fix a box 120 located below, and use the rotating device on the ground to make the guide block 142 enter the guide groove 130 through the flared shape at the bottom of the guide groove 130 through the horizontal structure. Then use the lifting device to lift it, so that the guide block 142 can move up and down in the guide groove 130.

[0045] The cooperation between the guide inclined surface 1421 and the flared shape at the bottom of the guide groove 130 makes it more convenient for the guide block 142 to gradually enter the stage of being sized to fit the guide block 142 and play a limiting role during the rising process.

[0046] In some examples, it further includes a transition plate 520. The transition plate 520 is arranged on the side of the support seat 510. There is a gap between the bottom of the transition plate 520 and the top of the lower box 120. The gap can prevent the transition plate 520 from interfering with the top of the lower box 120 when the support seat 510 vibrates and its height changes. The gap is smaller than the height of the guide block 142. In this way, it can not only ensure that the transition plate 520 does not interfere with the top of the lower box 120, but also provide effective transition guidance during the rising process of the guide block 142. The transition plate 520 has a transition chute 530 whose projection in the vertical direction is the same as that of the guide groove 130, so that part of the guide block 142 can enter the transition chute 530 before completely leaving the guide groove 130.

[0047] The main function of the transition plate 520 is to provide transitional guidance for the guide block 142 in the special case where the guide block 142 needs to completely leave the guide groove 130. When stacking and installing the box body 120, after the guide block 142 leaves the guide groove 130, it still needs to pass through the transition chute 530 to reach a height higher than the support base 510, so that the box body 120 can be horizontally moved above the support base 510.

[0048] The transition chute 530 provides temporary guidance and support for the guide block 142, preventing the guide block 142 from shifting or shaking after leaving the guide groove 130, ensuring the stability of the bottom of the upper box body 120 during the period when its height is higher than the top of the lower box body 120 and less than the top of the support base 510, and avoiding the loss of control of the connection between the box bodies 120 due to the loss of limit of the guide block 142, thus ensuring the safety of the operator and the convenience of the operator's operation.

[0049] In some examples, there are also two side baffles 540. The side baffles 540 are fixedly spaced on the top of the support base 510 by welding or high-strength bolts. The height of the side baffles 540 is higher than the height of the guide block 142. The two side baffles 540 are respectively used to abut against the two sides of the box body 120, so that the box body 120 slides along the length direction of the side baffles 540. The side baffles 540 are in the shape of rectangular plates, and the length is determined according to the size of the top of the support base 510 and the width of the box body 120, generally slightly longer than the width of the box body 120, ensuring that the lateral movement of the box body 120 on the support base 510 can be effectively restricted. The side baffles 540 mainly play the role of guiding and limiting the box body 120.

[0050] Working principle: When the height of the bottom of the box body 120 is higher than the support base 510, that is, after the guide block 142 leaves the transition chute 530, the two side baffles 540 can play a limiting role on the box body 120 from the side of the box body 120, avoiding the shaking of the box body 120 and helping to improve the convenience of positioning the box body 120.

[0051] The clamping plate 550 is arranged on the top of the support base 510. The sum of the height of the clamping plate 550 and the height of the guide block 142 is less than the height of the side baffle 540, so that the box body 120 can be lifted to a height where the guide block 142 is sufficient to cross the clamping plate 550 under the limiting action of the two side baffles 540. After the guide block 142 crosses the clamping plate 550, the operator operates the hoisting device to lower the box body 120, so that the connecting rod 141 enters the clamping groove 551, completing the longitudinal positioning of the box body 120 on the support base 510. The two ends of the clamping plate 550 respectively abut against the mutually close ends of the guide block 142 and the box body 120, thus completing the lateral positioning of the box body 120 on the support base 510. After the bottom of the box body 120 contacts the top of the support base 510, the vertical positioning of the box body 120 and the support base 510 can be completed.
