Description

Technical Field

[0001] This utility model belongs to the technical field of construction equipment, and in particular relates to a temporary power protection box for construction projects. Background Technology

[0002] Temporary power supply is an indispensable part of modern construction projects. To ensure construction safety and the normal operation of electrical equipment, various protective boxes are usually used to protect temporary electrical equipment. However, current temporary power supply protective boxes still face many challenges in actual construction environments.

[0003] First, construction sites are complex and changeable environments, often encountering severe weather such as rain, strong winds, and dust. Existing protective boxes are often poorly designed in terms of rain and dust protection. For example, the ventilation openings of some protective boxes may be directly exposed, allowing rainwater to easily enter the box and cause short circuits or even damage to the internal electrical equipment. Alternatively, their sealing is poor, failing to effectively prevent the entry of dust and debris commonly found on construction sites. Over time, this leads to dust accumulation on the equipment, affecting heat dissipation and service life. At the same time, some protective boxes are overly sealed in order to prevent dust and rain, which makes it difficult for heat to dissipate from the inside of the box. Especially when high-power equipment is running for a long time, the internal temperature of the box becomes too high, which not only affects the operating efficiency and stability of the equipment, but may even cause overheating failures or fires and other safety accidents.

[0004] Secondly, the ground conditions at construction sites are usually uneven, and there is movement of various mechanical equipment and personnel. When the protective box is placed, it is easy to sway due to the uneven ground, and it may even tip over when subjected to external impact. The existing protective boxes are often designed with simple bottom support structures, lacking sufficient stability. The connection strength between the support legs and the box body may also be insufficient, making it difficult to effectively bear the weight of the box body and internal equipment, and unable to cope with the complex working conditions at the construction site, thus posing a hidden danger to construction safety and affecting the stable power supply of temporary electrical equipment.

[0005] Therefore, this utility model proposes a temporary electrical protection box for construction projects, which aims to effectively solve the problems of insufficient rain and dust protection, low heat dissipation efficiency and poor stability of existing protective boxes.

The mounting pieces fit into the preset installation positions on the top left and right sides of the enclosure and are secured by bolts threaded through the pre-drilled holes in the mounting positions of the enclosure.

[0010] Preferably, the mating piece is inserted into the slot, which makes the installation and positioning of the breathable side plate more precise.

[0011] Preferably, the mounting plate is fitted to the preset mounting positions on the top left and right sides of the housing, ensuring close contact between the mounting plate and the housing and providing a good foundation for bolt fixing.

[0012] Preferably, the bolt passes through the reserved hole at the mounting position of the mounting plate and the housing, so as to achieve a firm connection between the mounting plate and the housing.

[0013] Preferably, the shield is located above the top of the breathable side panel, providing shielding protection for the top of the breathable side panel.

[0014] Preferably, the water guide hole is connected to the bottom of the card slot to ensure that rainwater that seeps into the card slot can be discharged in a timely manner.

[0015] Preferably, the support legs are connected to the bottom of the box, so that the weight of the protective box can be stably transferred to the supporting structure.

[0016] Preferably, the reinforcing rib is disposed at the connection between the support plate and the support leg, which further improves the overall structural strength and stability of the support structure.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Example

[0021] Please refer to Figure 1 and Figure 2 As shown in the figure, this utility model embodiment provides a temporary power protection box for construction projects, which aims to solve the structural defects and safety hazards in the prior art, such as insufficient protection of the box body, poor heat dissipation, and poor stability.

[0022] like Figure 1 and Figure 2 As shown, the temporary electrical protection box for this construction project includes a box body 1, a door 2 on the box body 1, a support structure 4 fixedly connected to the bottom of the box body 1, and a protective mechanism 3 on the side wall of the box body 1. The box body 1 serves as the core frame and equipment housing space of the entire protection box. The door 2 is used to open and close the box body 1 to block the influence of the external environment on the interior of the box body 1. The support structure 4 provides stable support for the protection box, and the protective mechanism 3 enables ventilation, heat dissipation, and rain protection for the interior of the box body 1.

[0023] To solve the above-mentioned technical problems, the core of the technical solution of this embodiment is that the temporary power supply protection box for construction projects also includes a protection mechanism 3, and the protection mechanism 3 and the aforementioned box body 1 form a specific structural cooperation and connection relationship.

[0024] Please refer to the following carefully. Figure 1 , Figure 3 and Figure 4 The core structure will be described in detail below: The protective mechanism 3 has a breathable side panel 31 with multiple evenly distributed breathable holes 32. These breathable holes 32 are L-shaped and cleverly designed to prevent rainwater from flowing back into the box 1, thus isolating the inside of the box 1 from external moisture while ensuring air circulation. Above the top of the breathable side panel 31, a shield 33 is integrally formed or fixedly connected. The shield 33 protrudes slightly from the breathable side panel 31 and its function is to prevent rainwater from directly hitting the top of the breathable side panel 31.

[0025] The bottom of the ventilated side panel 31 is provided with a connecting piece 34, which is inserted and fixed into the corresponding slot 35 at the bottom of the housing 1 to form a stable bottom connection. The bottom of the slot 35 communicates with the water guide hole 36, which penetrates the outer wall of the housing 1. Its function is to promptly drain any small amount of rainwater that may seep into the slot 35 to the outside of the housing 1. At the same time, the top edge of the ventilated side panel 31 is provided with an mounting piece 37. The mounting piece 37 is fixed through bolts 38 to the reserved holes at the preset installation positions on the left and right sides of the top of the housing 1. After the bolts 38 are tightened, the mounting piece 37 fits tightly with the housing 1, ensuring that the integrity and sealing of the ventilated side panel 31 and the housing 1 are strengthened at the top fixing point. This combination of connecting piece 34 and bolt 38 installation method ensures the convenience and firmness of the connection between the protective mechanism 3 and the housing 1, and its function is to provide an excellent rainproof, dustproof and heat dissipation environment for the inside of the housing 1.

[0026] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, in order to ensure accurate and stable positioning of the bottom of the breathable side plate 31, the mating piece 34 is designed to be inserted into the slot 35. This insertion method makes the installation process more convenient and accurate, while providing initial structural stability for subsequent bolt 38 fixing.

[0027] As another preferred embodiment, in order to ensure a firm and reliable connection between the mounting plate 37 and the top of the housing 1, the mounting plate 37 is designed to fit snugly against the preset mounting positions on the left and right top sides of the housing 1. This snug fit design increases the contact area, helps to disperse stress, and ensures a tighter connection after the bolts 38 are tightened, effectively preventing the ventilated side plate 31 from loosening under the influence of the external environment.

[0028] As another preferred embodiment, in order to reliably fix the mounting plate 37 to the housing 1, the bolt 38 is designed as a pre-drilled hole that passes through the mounting position of the mounting plate 37 and the housing 1. This through-fixing method is a common and reliable mechanical connection method. The tightening force of the threaded engagement ensures a stable connection between the protective mechanism 3 and the housing 1, thereby enhancing the impact resistance and wind resistance of the protective housing.

[0029] As another preferred embodiment, in order to effectively prevent rainwater from directly hitting the top of the breathable side panel 31, the shield 33 is designed to be located above the top of the breathable side panel 31. This covering arrangement forms a physical barrier, reducing the possibility of rainwater directly entering the vent 32, thereby improving the overall rainproof performance of the protective mechanism 3.

[0030] As another preferred embodiment, in order to promptly drain any small amount of rainwater that seeps into the slot 35, the water guide hole 36 is designed to communicate with the bottom of the slot 35. This communication design ensures that water does not accumulate at the bottom of the slot 35, preventing moisture from stagnating inside the slot 35, thereby effectively avoiding moisture and corrosion problems at the bottom or joints of the housing 1.

[0031] As another preferred embodiment, in order to provide a stable foundation support for the entire protective box, the support legs 41 are designed to directly connect with the bottom of the box body 1. This direct connection method ensures the effective transfer of load, avoids instability that may be caused by intermediate links, and allows the weight of the protective box to be evenly and effectively transferred to the support structure 4.

[0032] As another preferred embodiment, to enhance the overall strength and stability of the support structure 4, reinforcing ribs 43 are designed to be installed at the connection between the support plate 42 and the support leg 41. These reinforcing ribs 43 are typically rib-shaped or triangular in structure. By increasing the moment of inertia and bending stiffness of the cross section, they significantly improve the connection strength between the support plate 42 and the support leg 41, thereby ensuring that the support plate 42 can stably bear the weight of the enclosure 1 and the internal equipment, and ensuring the long-term stable operation of the protective enclosure during construction.

[0033] Working principle: First, install and fix the entire protective box. Insert the mating piece 34 at the bottom of the ventilated side plate 31 into the slot 35. Then, attach the mounting piece 37 to the preset installation position on the top left and right sides of the box body 1. Then, use bolts 38 to pass through the reserved holes of the mounting piece 37 and the box body 1. Rotate the bolts 38 until tightened to complete the fixing of the ventilated side plate 31 to the box body 1. The ventilated hole 32 on the inner side of the ventilated side plate 31 has an L-shaped structure, which prevents rainwater from flowing back into the box body 1, thus isolating the inside of the box body 1 from external moisture. During daily use, open the box door 2 and connect the temporary electrical equipment lines required for construction to the internal wiring terminals of the box 1. After completing the wiring, close the box door 2. The box door 2 prevents external dust and debris from entering the box 1. In rainy weather, the shield 33 prevents rainwater from directly hitting the top of the ventilated side plate 31. When a small amount of rainwater seeps into the slot 35, it is discharged through the water guide hole 36 connected to the bottom of the slot 35. The heat generated by the operation of the box 1 can be circulated through the ventilated holes 32 on the ventilated side plate 31 of the protective mechanism 3. Cold air from the outside enters the gap between the protective mechanism 3 and the box 1, exchanges with the hot air on the surface of the box 1 and carries away the heat, thus achieving heat dissipation. The legs 41 of the support structure 4 are connected to the box 1, providing stable support for the entire protective box and preventing it from tipping over due to uneven ground or external impact. The reinforcing ribs 43 of the support structure 4 enhance the connection strength between the support plate 42 and the legs 41, ensuring that the support plate 42 stably bears the weight of the box 1 and the internal equipment, ensuring that the protective box is in a stable working state during construction, and achieving safe protection and stable power supply for temporary electrical equipment used in construction projects.
