Description

TECHNICAL FIELD

[0001] The utility model relates to prefabricated cabin technical field especially relates to an anti -seismic prefabricated cabin. BACKGROUND

[0002] With the continuous progress and innovation of modern industrial technology, especially in the key fields of power, communication, energy storage, prefabricated cabin as an important container equipment has been widely used in various environments. The introduction of prefabricated cabin not only greatly improves the safety and convenience of the device, but also provides isolation, protection and support for the device. Especially in those extreme environments with strict requirements for device safety, such as vibration, earthquake, strong impact and other situations that may be encountered during transportation, the anti-seismic performance of prefabricated cabin becomes a crucial factor in its design. Traditional prefabricated cabin design often pays more attention to the stability and durability of the structure, and usually uses metal plates or steel plates and other materials to build the cabin body. However, these designs often do not fully consider the risk of damage or performance degradation of the equipment inside the cabin under the action of external vibration or impact. Especially in strong earthquake environment, if the cabin structure cannot effectively absorb and isolate the vibration, the safety of the internal equipment is difficult to be fully guaranteed. In addition, many existing anti-seismic design schemes are often too complex, which not only increases the manufacturing cost, but also is difficult to be widely promoted in practical application.

[0003] In the patent "a power prefabricated cabin damping base" (publication number CN207795946U, hereinafter referred to as prior art 1) discloses a damping base of prefabricated cabin, in prior art 1, through the cooperation of carefully designed damping module and damping block, the horizontal movement function of bottom frame relative to top frame is realized. The purpose of this design is to effectively reduce the shaking of top frame when prefabricated cabin is subjected to sudden external force in horizontal direction, so as to reduce the deformation degree of the overall structure. In this way, the adverse effects of rigid connection on power prefabricated cabin and its internal sensitive equipment can be significantly reduced.

[0004] Although the damping module and damping block have been set in prior art 1 to try to solve the shaking problem, its damping measures are limited to the bottom frame. Since prefabricated cabin is assembled by multiple components, it is inevitable to encounter vibration during transportation, or it will also be affected by vibration when natural disasters such as earthquake occur. These vibrations may cause the structure of prefabricated cabin to deform or even be damaged. Therefore, only setting damping structure in the bottom frame is not enough to absorb and alleviate external vibration from all directions, or the effect is not good; therefore, more comprehensive damping measures are needed to protect the integrity of prefabricated cabin and the safety of internal equipment. UTILITY MODEL CONTENTS

[0005] Therefore, the anti-seismic prefabricated cabin is provided in the embodiments of the present application to solve the problem that the prefabricated cabin in the prior art generally lacks effective shock absorption structure, especially under the influence of transportation, earthquakes or other vibration sources, which may cause damage to the equipment in the cabin or structural deformation.

[0028] Embodiment 1

[0029] Please refer to Figure 1The utility model embodiment provides an anti -seismic prefabricated cabin, in this embodiment, this anti -seismic prefabricated cabin is mainly used to install and protect energy storage device, and the energy storage device contains multiple battery clusters. In the prior art, the prefabricated cabin lacks effective anti -seismic protection measures, which leads to cracking, damage, even the internal energy storage unit is also damaged when the prefabricated cabin encounters strong vibration or earthquake etc. Natural disasters. Such a situation not only brings economic losses, but also may threaten the safety of personnel. Therefore, an anti -seismic prefabricated cabin is provided in this embodiment, by the application of reinforcing structure setting and anti -seismic material, ensure the use safety of cabin 100 and internal energy storage unit under the vibration condition, to reduce potential loss.

[0030] Please see Figure 1 In this embodiment, an anti -seismic prefabricated cabin is composed of multiple main components, including side plate 400, top plate 200 and bottom plate 300, these components are assembled together, form a solid cabin 100 structure. The cabin 100 is designed with a special accommodating cavity 110, this space is used to accommodate energy storage unit and various service components closely related to the operation of energy storage unit. These service components can include but not limited to cooling system components and fire extinguishing system components, they are essential to ensure the safe operation of energy storage unit. The top plate 200 is arranged to be installed at the top of the cabin 100, and the bottom plate 300 is located at the bottom of the cabin 100, which provides stable support for the cabin 100. As for the side plate 400, it is arranged between the top plate 200 and the bottom plate 300, which together enclose a closed cabin 100 space, not only ensure the safety of internal equipment, but also contribute to the improvement of anti -seismic performance.

[0031] Please see Figure 3 In this embodiment, the top plate 200 and the bottom plate 300 are arranged as shock -absorbing plates, the main purpose is to absorb and alleviate the vibration force from the outside, such as the vibration condition that may be encountered in the process of transporting prefabricated cabin, so that the structure of prefabricated cabin can be effectively protected. Specifically, these shock -absorbing plates include two parts of inner side plate 310 and outer side plate 320, a shock -absorbing layer 330 is arranged between the two layers of plates. In the shock -absorbing layer 330, a plurality of shock absorbers 340 (spring shock absorbers) are arranged, which can effectively absorb and disperse the impact force of external vibration on the top plate 200 and the bottom plate 300, so as to ensure the safety of the overall structure of prefabricated cabin.

[0032] In practical applications, the battery cluster of the energy storage unit is generally installed inside the cabin body 100 for transportation, and is installed after being transported to the destination. Since the prefabricated cabin itself has a certain length, it is more likely to be damaged by vibration, so the top plate 200 and the bottom plate 300 are set as shock-absorbing layers 330 to ensure that the prefabricated cabin unloads the impact on the top and bottom during transportation.

[0033] In applications, when the prefabricated cabin is subjected to strong vibration during transportation or use, if there is no effective shock-absorbing measure, the vibration energy will be directly transmitted to the equipment, which may cause internal parts to loosen, damage or malfunction, especially sensitive electronic components, energy storage units (batteries) and the like are easily affected by vibration. If the prefabricated cabin does not have a shock-absorbing system under strong vibration, the impact force of the vibration may cause the metal or other materials of the cabin body 100 to deform, crack or break, reducing the stability of the structure, and even causing the cabin body 100 to fail. Vibration may cause the connections, screws, fasteners, etc. inside the prefabricated cabin to loosen, affecting the overall structural stability of the cabin body 100, and in severe cases, it may cause parts to fall off or fall into the equipment, affecting the operation of the equipment or causing safety hazards.

[0034] Please refer to Figure 3 In this embodiment, a plurality of groups of mounting seats are arranged inside the shock-absorbing layer 330 of the inner side plate 310 and the outer side plate 320; these mounting seats are composed of first connecting ends 351 and second connecting ends 352; wherein the first connecting ends 351 are arranged on the inner side plate 310, and the second connecting ends 352 are arranged on the outer side plate 320; the two ends of the shock absorber 340 are respectively hinged with these first connecting ends 351 and second connecting ends 352.

[0035] In this embodiment, by arranging these mounting seats inside the shock-absorbing layer 330, stable hinged connection of the two ends of the shock absorber 340 with the inner side plate 310 and the outer side plate 320 can be realized, so as to ensure that the relative position between the inner and outer side plates 320 will not be offset when subjected to vibration or external force. These mounting seats provide dedicated connection points for the shock absorber 340, so that the shock absorber 340 can more efficiently play a role in absorbing and buffering vibration energy, while avoiding the problem of loosening or uneven stress caused by direct connection. By flexibly adjusting the structure to cope with vibration: the hinged design allows the shock absorber 340 to rotate freely within a certain range, thereby adapting to vibrations and impacts from different directions, significantly improving the dynamic response capability of the shock-absorbing system.

[0036] Further, please refer to Figure 3The damping layer 330 can effectively absorb external vibrations and attenuate them to the minimum, thereby reducing the transmission of vibration energy to the inside of the cabin 100 and protecting sensitive equipment inside the cabin from vibration. Improve the anti-vibration performance: The inner side plate 310 and the outer side plate 320 are connected by the articulated shock absorber 340, which can flexibly respond to multidirectional vibrations, not only withstand vertical impact, but also effectively buffer horizontal or oblique vibrations, thereby improving the overall anti-vibration capability of the cabin 100. The articulated design reduces the impact of stress concentration on the inner and outer side plates 320 in fixed connections, reduces fatigue damage caused by vibration, and prolongs the service life of the cabin 100 and the shock absorber 340.

[0037] The side plate 400 is provided with an internal hollow damping plate; the height of both ends of the damping plate is higher than the height of both sides of the damping plate; and the internal hollow part of the damping plate is provided with damping liquid 410, which facilitates the damping plate to unload external force and protect the safety of the prefabricated cabin.

[0038] Please refer to Figure 2 and Figure 4 The top of the damping plate is provided with an opening and is in communication with the internal hollow part of the damping plate; the damping plate passes through the opening and is provided with an inner plate 420 in the internal hollow part of the damping plate, and the inner plate 420 is arranged in the damping liquid 410. The inner plate 420 is also connected with the top plate 200, when vibration occurs, the inner plate 420 will move in the damping liquid 410, so that the external force is unloaded through the damping liquid 410, and due to the nature of the damping liquid 410, the movement of the damping plate in the damping liquid 410 will be limited by the damping liquid 410, so that the external force is unloaded, achieving the effect of shock absorption.

[0039] The top of the inner plate 420 is also provided with a clamping plate 430; the two ends of the clamping plate 430 are connected with the two ends of the damping plate, and the clamping plate 430 is used to limit the position of the inner plate 420, so that the inner plate 420 does not enter the damping liquid 410 completely, so that the damping liquid 410 is in a flowing state in the internal hollow part of the damping plate.

[0040] The setting height of the inner plate 420 is higher than the setting height of the damping plate, so that after the clamping plate 430 is connected with the two ends of the damping plate, a gap is provided at the top of the two ends of the damping plate, so that the inner plate 420 has a space for movement.

[0041] The damping plate is connected with the top plate 200 through the clamping plate 430, and the bottom of the damping plate is connected with the bottom plate 300. The top of the damping plate is provided with at least a first liquid groove 441 and a second liquid groove 442. The damping liquid 410 is limited in the damping plate through the first liquid groove 441 and the second liquid groove 442. Because the top of the damping plate is provided with a spacing, the damping liquid 410 may overflow. The first liquid groove 441 and the second liquid groove 442 lower the liquid level of the damping liquid 410, facilitating the storage of the damping liquid 410.

[0042] In the application process, the inner plate 420 can effectively absorb and disperse the vibration energy transmitted from the outside. When external force is applied from the bottom or the top, it will first encounter the shockproof plate, which will absorb and disperse part of the external force, and then further shock-absorbing treatment is carried out through the shock absorber 340, so that the vibration is relieved. When encountering a larger external force, the external force will be transmitted to the side plate 400, at which time the inner plate 420 will move in the damping liquid 410, and through this movement, the remaining external force is unloaded, thereby achieving the effect of shockproof. The damping liquid 410 is a special liquid used to slow down or control vibration and impact, and it has been widely used in many fields such as mechanical systems, hydraulic systems, shock-absorbing devices and automobile suspension systems. The damping liquid 410 can play a role mainly by relying on its unique viscosity and flow characteristics. These characteristics enable it to absorb vibration or impact energy, thereby reducing the vibration amplitude or damping vibration energy of the system, and further improving the stability of the equipment. The damping liquid 410 produces a damping effect through its flow resistance. When the equipment or mechanical system vibrates, the damping liquid 410 uses its flowability and viscosity to resist the flow generated by the vibration, converting the vibration energy into heat energy, which effectively reduces or eliminates unnecessary vibration. This damping process usually occurs inside the device, and the resistance generated by the flow of liquid or gas is used to offset the power of vibration, thereby achieving the purpose of damping.

[0043] When the external force is transmitted to the side plate 400, the inner plate 420 will move in the damping liquid 410. This movement ensures that the side plate 400 itself does not produce or produce less vibration, so that the damping liquid 410 can effectively offset the power generated by the vibration. Such a setting not only improves the damping effect, but also ensures the safe use of the prefabricated cabin and prevents structural damage or functional failure caused by excessive vibration.

[0044] In the embodiment, the overall shock absorption effect is effectively enhanced by arranging the first shock absorption plate 321 and the second shock absorption plate 322 in the outer side plate 320 and filling damping materials therebetween. The second shock absorption plate 322 is arranged with an opening, which provides a flexible hinge point for the connection of the shock absorber 340, so that the shock absorber 340 can be stably connected with the outer side plate 320 and play a role in the vibration process. The arrangement of the opening not only ensures the effective installation of the shock absorber 340, but also allows it to move freely during vibration, thereby better absorbing and relieving the vibration energy, and further improving the anti-vibration performance of the cabin body 100 and the protection effect of the equipment.

[0045] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the utility model, but not to limit them; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
