Description

Technical Field

[0001] The embodiments of the present invention relate to the field of mobile power station technology, and more specifically, to a dual-engine tracked mobile power station. Background Technology

[0002] In certain special environments, such as remote mountainous areas, field work sites, and emergency rescue sites, conventional power grid supply is often insufficient to meet the demand. Mobile power stations, as devices that can provide temporary power support, are widely used in various fields such as construction, oil exploration, mining, and emergency disaster relief.

[0003] Tracked mobile power stations utilize tracked assemblies for mobility, enabling them to adapt to complex and varied road conditions, such as muddy, rugged, and sandy terrain, and provide a stable power supply for construction equipment and emergency facilities. Tracked mobile power stations typically mount various component cabinets on the tracked assembly platform, including engine cabinets, generator cabinets, and battery cabinets.

[0004] The equipment within the cabinet needs to operate under good dust-free conditions. This is especially true in special environments, such as deserts, where high concentrations of sand and dust, small particle sizes, and high mobility make it easier for sand and dust to enter the cabinet. To address this issue, current tracked mobile power stations equip their cabinets with filter components for dust protection. However, in dusty environments, these filter components require frequent maintenance and replacement. Cleaning and replacement often necessitate removing the filter components for cleaning and reinstallation, which consumes considerable time and manpower.

[0005] Therefore, developing a dustproof structure for component cabinets that is easy to clean, quick to install, and easy to maintain is of great significance for improving the reliability of tracked mobile power stations in special environments and ensuring the continuity of power supply. Summary of the Invention

[0006] To overcome the above-mentioned defects, embodiments of the present invention provide a dual-engine tracked mobile power station, which solves the technical problem in the related art that the maintenance and replacement of dust filter components of mobile power stations are more frequent, time-consuming and labor-intensive in desert environments.

[0007] According to one aspect, at least one embodiment of the present invention provides a dual-engine tracked mobile power station, including a tracked walking assembly, a mounting platform disposed on the tracked walking assembly, a component cabinet disposed on the mounting platform, and a dustproof assembly;

[0008] The dustproof assembly includes a dustproof chamber, a filter layer, end plates, tension springs, and locking components. The dustproof chamber is located on the side of the component cabinet and communicates with the component cabinet. A dustproof window is provided on the side wall of the dustproof chamber. The filter layer is disposed inside the dustproof chamber and is corrugated and folded. The filter layer is used to seal the dustproof window. End plates are provided at both the upper and lower ends of the filter layer. Tension springs are connected between the two end plates and the inner wall of the dustproof chamber. The locking component is disposed through the side wall of the dustproof chamber and slides with the side wall of the dustproof chamber. The locking component is used to press against the side of the end plate away from the filter layer to limit the end plate.

[0009] After the locking member is released, the two end plates can move away from each other under the pull of the two tension springs, and cause the filter layer to flatten instantly to shake off the dust on the surface.

[0010] For example, the dual-engine tracked mobile power station provided in at least one embodiment of the present invention further includes:

[0011] Both sides of the filter layer are provided with corrugated elastic strips, which are used to make the filter layer fold in a corrugated shape when the filter layer returns to a folded shape from a flat shape.

[0012] For example, the dual-engine tracked mobile power station provided in at least one embodiment of the present invention further includes:

[0013] The dustproof chamber is equipped with two buffer plates located on the upper and lower sides of the filter layer, respectively. Each buffer plate has multiple springs on the side facing the filter layer. The multiple springs are spaced apart along the length of the filter layer and are used to abut against the end plate after the filter layer is instantly deployed to limit the movement of the end plate.

[0014] For example, the dual-engine tracked mobile power station provided in at least one embodiment of the present invention further includes:

[0015] The dustproof chamber is equipped with a blower airbag located inside the filter layer. The blower airbag has multiple air nozzles on the side facing the filter layer. Pressure plates are slidably arranged inside the dustproof chamber on the upper and lower sides of the blower airbag. The pressure plates on both sides can approach each other and squeeze the blower airbag so that the air nozzles blow airflow toward the filter layer.

[0016] For example, the dual-engine tracked mobile power station provided in at least one embodiment of the present invention further includes:

[0017] A lever is hinged to the dustproof chamber. One end of the lever is hinged to the end plate, and the other end is hinged to a pressure plate for pressing against the pressure plate. When the end plate is moved up and down by the tension spring, the lever can drive the pressure plate to press against the pressure plate and squeeze the blowing airbag, so that the air nozzle blows airflow toward the filter layer.

[0018] For example, the dual-engine tracked mobile power station provided in at least one embodiment of the present invention further includes:

[0019] The dustproof chamber and the dustproof window have two vertically spaced, arc-shaped sliding holes on their side walls. Each end of the two end plates is detachably equipped with a support rod, which extends horizontally through and out of the sliding hole. A lever is rotatably mounted on the outside of the dustproof chamber, which can move the support rod along the sliding hole so that the end plates move closer together and press against the filter layer to restore its folded shape.

[0020] For example, the dual-engine tracked mobile power station provided in at least one embodiment of the present invention further includes:

[0021] The dustproof window is equipped with multiple swing-type window leaves, which are connected by a connecting rod. The swing ends of the multiple window leaves are all hinged to the connecting rod. The connecting rod is used to drive the multiple window leaves to swing synchronously, so as to control the opening and closing of the dustproof window.

[0022] For example, the dual-engine tracked mobile power station provided in at least one embodiment of the present invention further includes:

[0023] The bottom wall of the dustproof chamber is provided with a dust collection port corresponding to the filter layer. A dust collection box is slidably installed in the dust collection port, and the dust collection box is used to collect the dust that falls off when the filter layer is unfolded.

[0024] For example, the dual-engine tracked mobile power station provided in at least one embodiment of the present invention further includes:

[0025] The dustproof chamber has an adjusting screw running through its top and bottom. The adjusting screw is threadedly connected to the dustproof chamber. An adjusting nut that is rotatably disposed outside the dustproof chamber is threadedly connected to the end of the adjusting screw. A hanging ring is provided on the end plate. One end of the tension spring is connected to the adjusting screw, and the other end has a hook for hooking the hanging ring.

[0026] For example, the dual-engine tracked mobile power station provided in at least one embodiment of the present invention further includes:

[0027] The dustproof chamber has a hinged door on its side wall, which is used to close the dustproof chamber, and the dustproof window is located on the door.

[0028] The beneficial effects of the embodiments of the present invention are as follows:

[0029] In this invention, the filter layer is corrugated and folded, significantly increasing the filtration area and thus improving filtration efficiency, protecting the equipment within the component cabinet from dust. When cleaning the filter layer is required, the operator operates the locking mechanism, causing it to slide and release its obstruction of the end plate. At this time, the elastic potential energy stored in the tension spring is released, and under the action of elastic force, the tension spring pulls the end plates apart. Since the end plates are connected to the filter layer, they can cause the filter layer to flatten instantly, thus causing the filter layer to vibrate. This vibration causes the dust adhering to the surface of the filter layer to fall off under inertia, achieving cleaning of the filter layer without the need to disassemble and reassemble it, saving time and manpower.

[0041] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it.

[0042] To keep the drawings concise, each drawing only schematically shows the parts relevant to the invention; these do not represent the actual structure of the product.

[0046] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0047] Tracked mobile power stations are portable power supply devices that integrate power generation systems and energy storage equipment, using a tracked chassis as their mobile platform. Combining the terrain adaptability of tracked mobility with the energy supply capacity of power generation equipment, they are mainly used in outdoor operations, emergency rescue, and power supply in remote areas.

[0048] The core power source of a tracked mobile power station is a diesel or gasoline engine, paired with a generator (such as a synchronous or asynchronous generator) to convert the engine's mechanical energy into electrical energy, outputting AC or DC power to meet the power supply needs of different equipment. Some large tracked mobile power stations are also equipped with dual engines to meet high-power generation requirements. Battery packs are configured to store electrical energy for peak-shifting power supply or emergency backup. Furthermore, the engine, generator, and battery pack are also equipped with component cabinets to meet dust protection requirements.

[0049] The tracked design of the tracked mobile power station enables it to be used in complex terrain operations such as construction, oil exploration, mining, and emergency rescue. It does not rely on the power grid and can serve as a temporary power station to supply power to engineering machinery, communication equipment, rescue tools, etc.

[0050] like Figures 1-9The diagram illustrates a dual-engine tracked mobile power station according to an embodiment of the present invention, comprising a tracked walking assembly 1, a mounting platform 2 mounted on the tracked walking assembly 1, a component cabinet assembly 3 mounted on the mounting platform 2, and a dustproof assembly 4. A dustproof chamber 401 is located on the side wall of the component cabinet assembly 3 and communicates with the interior of the component cabinet assembly 3. A dustproof window 405 is provided on the side wall of the dustproof chamber 401 to allow outside air to enter the component cabinet assembly 3. A filter layer 402 is installed inside the dustproof chamber 401 and can completely seal the window, preventing sand and dust particles from entering the component cabinet assembly 3. The filter layer 402 is corrugated and folded to form numerous pleats, increasing the filtration area. End plates 403 are provided at both the upper and lower ends of the filter layer 402, serving to fix and support the filter layer 402. Tension springs 404 connect the end plates 403 to the inner wall of the dustproof chamber 401, and one end plate 403 can connect to multiple tension springs 404 to ensure uniform tension. The locking element 5 penetrates the side wall of the dust chamber 401 and can slide. When the locking element 5 is inserted into the dust chamber 401, it abuts against and blocks the movement of the end plate 403, thereby overcoming the tension of the tension spring 404 and keeping the filter layer 402 in a corrugated folded working state. When it is necessary to clean the filter layer 402, the operator only needs to slide the locking element 5 to release the obstruction of the end plate 403.

[0051] Working Principle: The corrugated folds of filter layer 402 significantly increase the filtration area, thereby improving filtration efficiency and protecting the equipment inside component cabinet 3 from dust. When cleaning filter layer 402 is required, the operator operates locking component 5, causing it to slide and release its obstruction of end plate 403. At this time, the elastic potential energy stored in tension spring 404 is released, and under the action of elastic force, tension spring 404 pulls end plates 403 away from each other. Since end plate 403 is connected to filter layer 402, end plate 403 can cause filter layer 402 to flatten instantly, thereby causing filter layer 402 to vibrate. Vibration can shake off the dust adhering to the surface of filter layer 402 under inertia, realizing the cleaning of filter layer 402 without disassembling and reinstalling it, saving time and manpower.

[0052] In some examples, such as Figure 8 As shown, a corrugated elastic strip 406 is provided along the length of the filter layer 402 on its side. The corrugated shape of the elastic strip 406 is the same as the corrugated shape of the filter layer 402 after folding. When the filter layer 402 is instantly flattened and dust is shaken off under the action of the tension spring 404, it is necessary to restore the filter layer 402 to its corrugated folded state. Since the elastic strip 406 itself is elastic and corrugated, the elastic strip 406 can apply a force to the filter layer 402 in the folding direction, guiding the filter layer 402 to fold according to the corrugated shape of the elastic strip 406, ensuring that the filter layer 402 still maintains its corrugated shape after folding.

[0053] Inside the dust chamber 401, buffer plates 407 are respectively installed on the upper and lower sides of the filter layer 402. The buffer plate 407 is a rectangular flat plate, with multiple spring sheets 408 spaced apart along its length on the side of the buffer plate 407 facing the filter layer 402. When the filter layer 402 is instantaneously unfolded under the action of the tension spring 404, it gradually flattens out as the end plate 403 moves rapidly. When the filter layer 402 is flattened to its maximum extent, if the tension spring 404 continues to apply excess tension, the end plate 403 will abut against the spring sheets 408 on the buffer plate 407. The spring sheets 408 undergo elastic deformation upon impact from the end plate 403, absorbing the impact force transmitted by the end plate 403 through elastic deformation, thereby achieving a buffering effect. This prevents the filter layer 402 from being damaged due to excessive tension, ensuring that the filter layer 402 can operate continuously and stably.

[0054] The elastic strip 406 ensures that the filter layer 402 accurately returns to its corrugated folded state after cleaning, guaranteeing the consistency of its shape after each fold. The buffer plate 407 and spring 408 provide protection for the filter layer 402 during unfolding. After the filter layer 402 is flattened to its limit position, the spring 408 buffers excess tension on the end plate 403, preventing damage from overstretching. This extends the service life of the filter layer 402, reduces the frequency of replacement due to damage, and lowers maintenance costs.

[0055] In some examples, such as Figure 5 , 6 As shown, the blowing airbag 6 is located inside the dustproof chamber 401 on the side of the filter layer 402 facing away from the dustproof window 405. Multiple air nozzles 601 are evenly distributed on the side of the blowing airbag 6 facing the filter layer 402. Pressure plates 602 are provided on both the upper and lower sides of the blowing airbag 6. A lever 7 is hinged inside the dustproof chamber 401; one end of the lever 7 is hinged to an end plate 403, and the other end is hinged to a pressure plate 701 that abuts against the pressure plate 602. When the end plate 403 moves under the action of the tension spring 404, the pressure plate 701 moves accordingly through the transmission action of the lever 7, squeezing the pressure plate 602, and thus squeezing the blowing airbag 6, causing the air nozzles 601 to blow airflow towards the filter layer 402. The blowing airbag 6 is made of elastic material and has a tendency to self-recover; during the recovery process, air can be re-inhaled by the air nozzles 601, awaiting the next blowing action.

[0056] A sliding hole 409 is provided on the side wall of the dustproof chamber 401. The sliding hole 409 is arc-shaped, and its length direction is consistent with the moving direction of the end plate 403. A support rod 410 is detachably provided on the end plate 403. The support rod 410 passes through the sliding hole 409 and protrudes from the outer wall of the dustproof chamber 401 to cooperate with the lever 411. The lever 411 is rotatably mounted on the outer wall of the dustproof chamber 401. The lever 411 can be operated manually or driven to rotate by a motor installed on the outer wall of the dustproof chamber 401.

[0057] Working Principle: When the tension spring 404 moves the two end plates 403 away from each other, the end plates 403 move the pressure plate 701 at the other end through the hinged lever 7. Under the action of the pressure plate 701, the pressure plates 602 on both sides of the blowing airbag 6 move closer together, thus squeezing the blowing airbag 6. After being squeezed, the internal gas of the blowing airbag 6 is blown towards the filter layer 402 through the nozzle 601. This airflow impacts the surface of the filter layer 402, helping the dust adhering to the filter layer 402 to be removed more effectively, further improving the cleaning effect of the filter layer 402. The mechanism cleverly utilizes the movement of the end plates 403 driven by the tension spring 404, and achieves the linkage of the blowing action of the blowing airbag 6 through the lever 7. When the filter layer 402 is flattened, it can also provide additional blowing airflow to help the dust fall off, thereby improving the cleaning effect.

[0058] When multiple flattening and dust removal actions are required for the filter layer 402, the motor is started to drive the lever 411 to rotate. The lever 411 moves the support rod 410, which in turn moves the end plate 403, causing the filter layer 402 to return to its folded state. As the lever 411 continues to rotate, the moment it disengages from the support rod 410, the tension of the tension spring 404 acts on the end plate 403 again, causing the end plates 403 to move away from each other. The filter layer 402 instantly flattens and shakes off the dust. At the same time, the blowing air bag 6 also blows air to assist in dust removal due to the lever 7, and this cycle continues. Through the continuous rotation of the lever 411, multiple flattening and dust removal actions of the filter layer 402 are achieved, improving cleaning efficiency.

[0059] In some examples, such as Figure 2 , 3 As shown, multiple window leaflets 8 are installed inside the dustproof window 405. Each window leaflet 8 is a rectangular thin sheet. The middle of each window leaflet 8 is hinged to the inner wall of the dustproof window 405, and its ends are hinged to a connecting rod 9. The swinging ends of all window leaflets 8 are hinged to the connecting rod 9, allowing the connecting rod 9 to swing all window leaflets 8 synchronously when it moves. The operator controls the movement of the connecting rod 9 by pulling or pushing the handle, thereby opening or closing multiple window leaflets 8 simultaneously, thus controlling the opening and closing state of the dustproof window 405.

[0060] A dust collection port 412 is located on the bottom wall of the dust chamber 401, directly below the filter layer 402. The edge of the dust collection port 412 has a sliding groove that matches the retaining strip on the edge of the dust collection box 413, allowing the dust collection box 413 to slide in and out of the dust collection port 412. The dust collection box 413 is used to collect dust that falls off when the filter layer 402 is unfolded. Operators can periodically remove the dust collection box 413 from the dust collection port 412 for cleaning.

[0061] Working Principle: Under normal operating conditions, the dustproof window 405 is open, allowing outside air to enter the component cabinet 3 through the filter layer 402, achieving normal ventilation and dustproof functions. When cleaning the filter layer 402 is required, to prevent the shaken-off dust from escaping through the gaps in the window leaf 8 and causing secondary pollution, the operator operates the connecting rod 9, causing multiple window leaf 8s to swing in the opposite direction, closing the dustproof window 405 and isolating the interior of the dustproof chamber 401 from the outside. At this time, the dust shaken off during the cleaning process of the filter layer 402 can only fall inside the dustproof chamber 401. When dust is shaken off during the cleaning process of the filter layer 402, since the dustproof window 405 is closed, the dust can only fall under the action of gravity and falls into the dust collection box 413 for centralized collection. Regularly cleaning the dust collection box 413 can keep the interior of the dustproof component 4 clean and ensure its normal operation.

[0062] In some examples, such as Figure 7 As shown, an adjusting screw 10 is provided through and slides along the inner wall of the dustproof chamber 401. An adjusting nut 11 is rotatably installed on the outer wall of the dustproof chamber 401, and the adjusting nut 11 is threadedly connected to the adjusting screw 10. When the adjusting nut 11 is rotated, the adjusting screw 10 will make a linear motion, thereby adjusting the tension of the tension spring 404. A hanging ring 414 is provided on the end plate 403. One end of the tension spring 404 is connected to the adjusting screw 10, and the other end is provided with a hook 415. The hook 415 can be hooked onto the hanging ring 414 to connect the tension spring 404 to the end plate 403. A box door 12 is hinged to the side wall of the dustproof chamber 401, and a dustproof window 405 is provided on the box door 12. Opening the box door 12 facilitates operation of the filter layer 402 and other internal structures.

[0063] Working principle: By rotating the adjusting nut 11, the position of the adjusting screw 10 is changed, thereby adjusting the tension of the tension spring 404 to achieve the best flattening and dust removal effect of the filter layer 402. When the filter layer 402 needs to be replaced, first open the box door 12, and then release the hinge between the end of the lever 7 and the end plate 403, for example, by pulling out the hinge shaft between the two, so that the lever 7 is separated from the end plate 403. Next, remove the hook 415 at the end of the tension spring 404 from the hanging ring 414 on the end plate 403, thus releasing the connection of the filter layer 402, which can then be easily removed for replacement. This design makes the replacement process of the filter layer 402 simple and convenient, without complicated tools and operating procedures, thus improving maintenance efficiency.
