Description

Technical Field

[0001] This invention belongs to the field of modular power station technology, and in particular relates to a protective device for the output port of a modular power station. Background Technology

[0002] In extreme and harsh environments such as high altitudes, deserts, and islands, traditional power supply methods are often difficult to operate stably due to natural conditions. As a core piece of equipment for mobile emergency power supply, the power output port of the modular power station is a key interface for power transmission. It is exposed to complex outdoor environments for a long time and is susceptible to erosion from wind, sand, rain, snow, salt spray, high and low temperatures, and vibration. Therefore, a protective device is needed to protect the power output port.

[0003] For example, Chinese Patent CN223156512U discloses a rainproof device for the output port of a modular power station, which includes a cabin plate with a pre-drilled opening for cable extension. It also includes a cable adapter plate installed on one side of the cabin. The cable adapter plate includes a mounting plate and an adapter plate body. The mounting plate is fixedly connected to the periphery of the opening in the cabin plate, and the adapter plate body is located at the opening in the cabin plate and tilted to the side inside the cabin. The adapter plate body is fixedly connected to the mounting plate.

[0004] However, considering that the adapter board is tilted towards the inside of the cabin, the output port faces inward rather than outward, making it difficult to reach the tilted area inside the cabin with hands and wiring tools. When docking, it is necessary to bend over or lean out to operate, and the range of motion of the wrist and arm is limited by the inner cavity wall of the cabin. It is also inconvenient to plug and unplug cables. Summary of the Invention

[0005] The purpose of this invention is to provide a protective device for the output port of a modular power station. By first inserting the cable socket into the rotating plate, and then driving the threaded sleeve along the composite groove through the lead screw, the rotating plate is rotated in conjunction with the cable socket to be adjusted to an inward tilt position, thus solving the problem of the cable connector insertion and extraction force and the difficulty in operating the fixed tilt interface.

[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0007] This invention relates to a protective device for the output port of a modular power station, comprising a modular power station with an installation port on its side wall and a protective plate rotatably connected thereto for sealing the installation port. A drive assembly is fixedly connected to the inner wall of the modular power station, and a rotating assembly is disposed on the inner wall of the drive assembly. The rotating assembly includes a rotating plate that can be flipped from the installation port toward the interior of the modular power station. An output port is fixedly connected to the surface of the rotating plate. The drive assembly includes a first sleeve fixedly connected to the inner wall of the modular power station, and the first sleeve is coaxially arranged with the rotation center of the rotating plate. After a cable connector is inserted into the output port of the rotating plate, the drive assembly drives the rotating plate to rotate around the axis of the first sleeve, causing the rotating plate to flip toward the interior of the modular power station and tilt inwards.

[0008] As a preferred embodiment of the present invention, the drive assembly includes a bearing frame fixedly connected to the inner wall of the modular power station and a drive motor. The bearing frame is rotatably connected to a lead screw, and the lead screw is connected to the drive motor via a gear set.

[0009] The lead screw is arranged axially inside the first sleeve, and the lead screw is fitted with a threaded sleeve, which is connected to the rotating plate in a transmission manner.

[0010] As a preferred embodiment of the present invention, the first sleeve sidewall is provided with a straight groove in the axial direction and a flip groove in the circumferential direction, and one end of the flip groove is connected to one end of the straight groove.

[0011] The threaded sleeve is slidably connected to the flip-over slot. The rotating plate has a slide rail. A slider is fixedly connected to the outer wall of the threaded sleeve. The slider passes through the straight slot and slides in cooperation with the slide rail. When the slider is in the flip-over slot, the threaded sleeve cannot move. The threaded sleeve is rotated by the lead screw, which in turn causes the rotating plate to flip. When the threaded sleeve rotates the slider to the position of the straight slot, the threaded sleeve slides along the straight slot by the lead screw.

[0012] As a preferred embodiment of the present invention, an arc-shaped plate is fixedly connected to the inner wall of the modular power station, and the center of the arc-shaped plate is concentrically set with the first sleeve.

[0013] As a preferred embodiment of the present invention, the rotating plate is fixedly connected to a scraper, which slides on the surface of the arc-shaped plate.

[0014] As a preferred technical solution of the present invention, the inner wall of the modular power station is fixedly connected with a limiting component, the limiting component including a first mounting plate and a second mounting plate, the first mounting plate and the second mounting plate being located on both sides of the rotating plate and fitting against the side of the arc-shaped plate.

[0015] As a preferred embodiment of the present invention, a limiting groove is formed on the surface of the first mounting plate, and the rotating plate is slidably connected to the limiting groove.

[0016] As a preferred embodiment of the present invention, the lead screw surface is threaded with a driving component, and the surface of the rotating plate is provided with a blocking component, the blocking component being positioned opposite to the output port.

[0017] The second mounting plate has a through hole, and the through hole is opposite to the position of the blocking component after the rotating plate is flipped into the modular power station.

[0018] The lead screw is threadedly connected to a driving component, which includes a movable rod threadedly connected to the lead screw. One end of the movable rod is slidably connected to the inner wall of the modular power station, and the other end is fixedly connected to a top rod. The top rod is used to pass through the through hole and push the blocking component to lock the cable socket.

[0019] As a preferred technical solution of the present invention, the blocking assembly includes a second sleeve fixedly connected to the side of the rotating plate, and the side wall of the second sleeve is provided with a spiral groove.

[0020] The second sleeve is fitted with a spring and a movable column. The movable column is fixedly connected to a protrusion that passes through the spiral groove. The movable column is pushed by the push rod, so that the protrusion moves spirally along the spiral groove, so that the protrusion abuts against the side of the cable socket away from the output port, thereby locking the cable socket.

[0021] In a preferred embodiment of the present invention, the rotating plate is fixedly connected to a mounting base, and the top rod is rotatably connected to the moving rod.

[0022] The present invention has the following beneficial effects:

[0023] 1. This invention uses the screw and the flip-out slot and straight slot on the first sleeve to form a composite motion track, enabling the threaded sleeve to move in both rotation and linear motion. This divides the rotational motion input by the motor into two stages. First, the cable socket is inserted into the rotating plate, and the rotating plate is driven to rotate around the axis to a preset tilt angle through the first stage, realizing the attitude adjustment of the cable socket from horizontal insertion to tilted positioning. The second stage pushes the driving component forward linearly, causing the blocking component to perform a locking action.

[0024] 2. This invention provides a three-dimensional constraint on the movement trajectory of the rotating plate by setting limiting components on both sides of the rotating plate and combining them with the bottom arc plate. This effectively prevents the rotating plate from shifting left and right, moving up and down, and swaying around during the flipping process, so that it is tilted along the preset trajectory. During the resetting process of the rotating plate, the scraper is simultaneously driven to scrape the surface of the arc plate to push out impurities, thus achieving cleaning in motion without the need for an additional drive device.

[0025] 3. This invention, by setting a second sleeve with a spiral groove and a movable column with a protrusion, when subjected to the linear thrust of the driving component, the movable column performs a combined rotation and propulsion motion along the spiral groove, pressing the cable socket in a spiral tightening manner. The locking force is uniform and reliable. The spring provides an automatic reset force after the drive shaft is withdrawn, causing the movable column to rotate in the opposite direction and exit, achieving fast and safe self-unlocking and effectively preventing the interface from loosening.

[0026] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0041] Example 1

[0042] Please see Figure 1 As shown, the present invention is a protective device for the output port of a modular power station, including a modular power station 1, an installation port 10 opened on the side wall of the modular power station 1, and a protective plate 11 rotatably connected to it for sealing the installation port 10.

[0043] A drive assembly 3 is fixedly connected to the inner wall of the modular power station 1, and a rotating assembly 2 is provided on the inner wall of the drive assembly 3; the rotating assembly 2 includes a rotating plate 21 that can be flipped into the interior of the modular power station 1 through the mounting port 10, and an output port is fixedly connected to the surface of the rotating plate 21.

[0044] The drive assembly 3 includes a first sleeve 33 fixedly connected to the inner wall of the modular power station 1, and the first sleeve 33 is coaxially arranged with the rotation center of the rotating plate 21. After the cable socket is plugged into the output port of the rotating plate 21, the drive assembly 3 drives the rotating plate 21 to rotate around the axis of the first sleeve 33, so that the rotating plate 21 flips towards the inside of the modular power station 1 and tilts inward.

[0045] When no cable connection is required, the protective plate 11 rotates to cover the surface of the modular power station 1, completely shielding the installation port 10, thereby achieving the protective effects of dust prevention, foreign object prevention, and safety isolation.

[0046] When the modular power station needs to output power to the outside, the modular power station is started by the control system and enters the working state. At this time, the protective plate 11 rotates in the opposite direction, switching from the initial vertical covering state to the horizontal unfolding state, which not only protects the outer periphery of the installation port 10, but also provides operating space for the cable plug-in.

[0047] After the operator plugs the cable socket into the output port on the surface of the rotating plate 21, the drive assembly 3 drives the rotating plate 21 and the cable socket together to rotate inward toward the inside of the modular power station, so that it maintains a stable plugging posture with its inward tilt.

[0048] like Figure 3 , Figure 5 , Figure 6 As shown, the drive assembly 3 includes a bearing frame 310 fixedly connected to the inner wall of the modular power station 1 and a drive motor 36. The bearing frame 310 is rotatably connected to a lead screw 31, and the lead screw 31 is connected to the drive motor 36 through a gear set 35.

[0049] The lead screw 31 is arranged axially inside the first sleeve 33. The lead screw 31 is fitted with a threaded sleeve 32, which is connected to the rotating plate 21. The working torque of the drive motor 36 drives the gear set 35 to rotate, and synchronously drives the lead screw 31 to rotate around its own axis. Since the threaded sleeve 32 has no circumferential limit, the circumferential rotation of the lead screw 31 will drive the threaded sleeve 32 to rotate synchronously. At this time, the circumferential rotation of the threaded sleeve 32 will be directly transmitted to the rotating plate 21, causing the rotating plate 21 to rotate synchronously around the axis of the first sleeve 33, and finally driving the rotating plate 21 to rotate towards the inside of the modular power station 1 to the preset inward tilting state.

[0050] like Figure 5 , Figure 6 As shown, the first sleeve 33 has a straight groove 331 axially opened on the side wall and a turning groove 330 opened in the circumferential direction. The turning groove 330 is connected to one end of the straight groove 331.

[0051] The threaded sleeve 32 is slidably connected to the tilting slot 330. The rotating plate 21 has a slide rail 22. A slider 320 is fixedly connected to the outer wall of the threaded sleeve 32. The slider 320 passes through the straight slot 331 and slides in cooperation with the slide rail 22. When the slider 320 is within the tilting slot 330, the threaded sleeve 32 cannot move. The threaded sleeve 32 rotates via the lead screw 31, which in turn causes the rotating plate 21 to tilt. When the threaded sleeve 32 rotates the slider 320 to the position of the straight slot 331, the threaded sleeve 32 slides along the straight slot 331 via the lead screw 31. (The last sentence appears to be incomplete and possibly refers to the activation of the modular power station 1.) The drive motor 36 is fixedly installed in the cavity. The output port of the drive motor 36 outputs torque to drive the lead screw 31 to rotate around its own axis. Since the threaded sleeve 32 has no circumferential limit and is connected to the lead screw 31 through the lead screw nut transmission, the circumferential rotation of the lead screw 31 drives the threaded sleeve 32 to rotate synchronously. At the same time, under the action of the screw transmission, the threaded sleeve 32 rotates along the flip groove 330 of the first sleeve 33 and synchronously drives the rotating plate 21 to flip. When the threaded sleeve 32 reaches the straight groove 331, the threaded sleeve 32 will move along the inner wall of the straight groove 331, so that the slider 320 slides on the inner wall of the slide rail 22.

[0052] When the threaded sleeve 32 slides along the flip-over slot 330, the slider 320 fixed on its surface slides synchronously in the slide rail 22 of the rotating plate 21. The slider 320 applies a directional thrust to the inner wall of the slide rail 22. Under the action of the thrust of the slider 320 and the trajectory constraint of the slide rail 22, the rotating plate 21 rotates around the axis of the first sleeve 33 and rotates in the same direction as the rotating plate 21 to the inside of the container power station 1 until the threaded sleeve 32 slides to the preset end position of the flip-over slot 330, and the rotating plate 21 reaches the preset inward tilting state.

[0053] like Figure 2 As shown, an arc-shaped plate 24 is fixedly connected to the inner wall of the modular power station 1, and the center of the arc-shaped plate 24 is concentrically set with the first sleeve 33.

[0054] like Figure 2 As shown, a scraper 23 is fixedly connected to the rotating plate 21, and the scraper 23 slides on the surface of the arc plate 24. While the rotating plate 21 rotates, the rotating plate 21 drives the fixedly connected scraper 23 to move synchronously. Since the arc contour of the arc plate 24 is adapted to the rotation trajectory of the rotating plate 21, the scraper 23 always slides in contact with the surface of the arc plate 24, and scrapes away the dust, debris and other pollutants attached to the surface of the arc plate 24 during the sliding process, so as to achieve synchronous cleaning.

[0055] Specifically, during the scraping action, after the cable insertion and removal operation is completed, if impurities accumulate on the surface of the arc plate 24, when the rotating plate 21 is rotated and reset around the axis of the first sleeve 33, the scraper 23 moves synchronously in the opposite direction with the rotating plate 21. During this reset process, the scraper 23 and the surface of the arc plate 24 remain in contact and slide, thereby pushing the impurities accumulated on the surface of the arc plate 24 out along the sliding trajectory, thus achieving impurity cleaning.

[0056] like Figure 3 , Figure 4 As shown, a limiting component 4 is fixedly connected to the inner wall of the modular power station 1. The limiting component 4 includes a first mounting plate 41 and a second mounting plate 42. The first mounting plate 41 and the second mounting plate 42 are located on both sides of the rotating plate 21 and are attached to the side of the arc plate 24. When the rotating plate 21 rotates, its bottom slides along the surface of the arc plate 24. The limiting components 4 on both sides of the rotating plate 21 act synchronously to prevent the rotating plate 21 from shifting left or right or shaking when it flips over, and to prevent external dust from entering the inner cavity of the modular power station 1.

[0057] like Figure 3 , Figure 4 As shown, a limiting groove 410 is provided on the surface of the first mounting plate 41, and the rotating plate 21 is slidably connected to the limiting groove 410. The second mounting plate 42 abuts against the other side of the rotating plate 21. When the threaded sleeve 32 slides along the flip groove 330, the slider 320 rolls in the slide rail 22 of the rotating plate 21 and applies a directional thrust, driving the rotating plate 21 to rotate around the axis of the first sleeve 33 toward the inside of the container power station 1. One side of the rotating plate 21 slides along the limiting groove 410 of the first mounting plate 41, and the other side is always abutting against the second mounting plate 42. The double constraint avoids left and right deviation and swaying. The bottom of the rotating plate 21 slides along the surface of the arc plate 24, blocking downward movement and limiting the flipping trajectory. When the threaded sleeve 32 slides to the preset end point of the flip groove 330, the bottom of the rotating plate 21 slides to the end of the arc plate 24, one side is abutting against the end of the limiting groove 410, and the other side is still abutting against the second mounting plate 42. The rotating plate 21 is stably maintained in the preset inward tilting state.

[0058] The control drive motor 36 rotates in reverse, which drives the lead screw 31 to rotate in reverse via the gear set 35. One side of the rotating plate 21 slides in reverse along the limiting groove 410, while the other side remains in contact with the second mounting plate 42. The bottom slides in reverse along the arc plate 24. The triple limiting synchronously constrains the reset trajectory. The scraper 23 slides in reverse along the surface of the arc plate 24, pushing impurities out of the surface of the arc plate 24. When the threaded sleeve 32 resets to the position where the flip groove 330 and the straight groove 331 connect, the rotating plate 21 returns to its initial posture that matches the mounting port 10. Each limiting structure returns to its initial constraint state. Then, the cable socket is pulled out, and the protective plate 11 is reset to the vertical covering state. The modular power station 1 returns to its initial protective state.

[0059] Example 2

[0060] like Figure 3 , Figure 5 , Figure 6 As shown, a drive component 34 is threadedly connected to the surface of the lead screw 31, and a blocking component 5 is provided on the surface of the rotating plate 21. The blocking component 5 is positioned opposite to the output port.

[0061] The second mounting plate 42 has a through hole 420, and the through hole 420 is opposite to the position of the blocking component 5 after the rotating plate 21 is flipped into the container power station 1.

[0062] A drive member 34 is threadedly connected to the surface of the lead screw 31. The drive member 34 includes a movable rod 340 threadedly connected to the lead screw 31. One end of the movable rod 340 is slidably connected to the inner wall of the modular power station 1, and the other end is fixedly connected to a push rod 341. The push rod 341 is used to pass through the through hole 420 and push the blocking assembly 5 to act, thereby locking the cable socket through the blocking assembly 5. The blocking assembly 5 includes a second sleeve 52 fixedly connected to the side of the rotating plate 21. The side wall of the second sleeve 52 is provided with a spiral groove 520.

[0063] like Figure 9 , Figure 10 As shown, the second sleeve 52 is fitted with a spring 54 and a moving post 53. The moving post 53 is fixedly connected to a protrusion 530 that penetrates the spiral groove 520. The protrusion 530 is pushed by the push rod 341 to move the moving post 53 spirally along the spiral groove 520, so that the protrusion 530 abuts against the side of the cable socket away from the output port, thereby locking the cable socket. The protective plate 11 is in a horizontally open state, and the cable socket is connected to the output port of the rotating plate 21. In the initial state, the threaded sleeve 32 is located at the junction of the flip groove 330 and the straight groove 331, and the slider 320 slides with the slide rail 22. The rotating plate 21 is connected, with one side embedded in the initial end of the limiting groove 410 and the other side abutting against the second mounting plate 42. The bottom is embedded in the initial end of the sliding groove 240. The driving component 34 is located at the initial position of the lead screw 31. The top rod 341 does not press against the blocking component 5. The drive motor 36 is started to continuously output torque and drives the lead screw 31 to rotate around its own axis through the gear set 35. The rotation of the lead screw 31 drives the threaded moving rod 340 to slide axially along the first sleeve 33. The moving rod 340 drives the top rod 341 to move synchronously. The top rod 341 slides along the through hole 420 of the second mounting plate 42 and gradually approaches the blocking component 5.

[0064] When the threaded sleeve 32 moves to the connection between the flip groove 330 and the straight groove 331, it continues to move in a straight line along the straight groove 331. The motion relationship between the threaded sleeve 32 and the rotating plate 21 changes from rotation drive to relative sliding. The rotating plate 21 maintains a fixed tilt angle, while the threaded sleeve 32 continues to move forward.

[0065] When the push rod 341 moves forward in a straight line with the moving rod 340, its end directly acts on the moving column 53, pushing the moving column 53 to move forward against the elastic force of the spring 54. Since the protrusion 530 fixedly connected to the moving column 53 forms a sliding fit with the spiral groove 520 on the inner wall of the second sleeve 52, the protrusion 530 is driven by the curved surface of the spiral groove 520 while moving forward, thereby forcing the moving column 53 to rotate. Thus, the moving column 53 moves forward in a spiral motion while rotating, eventually driving the protrusion 530 to the end of the spiral groove 520 and abutting at the cable socket. When the push rod 341 retracts backward, the spring 54 releases its stored energy, pushing the moving column 53 to reset. At this time, the protrusion 530 slides in the opposite direction along the spiral groove 520 under the action of the spring force, driving the moving column 53 to move backward while rotating in the opposite direction, thereby smoothly releasing the pressing state on the cable socket.

[0066] like Figure 3 As shown, the rotating plate 21 is fixedly connected to the mounting base 51, and the push rod 341 is rotatably connected to the moving rod 340; the rotatable connection between the push rod 341 and the moving rod 340 avoids excessive wear of the push rod 341 when driving the moving column 53 to rotate.
