[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1

[0027] This utility model provides an outdoor large-capacity fire sandbox, such as Figure 1As shown, the sandbox includes: a housing 1, a first movable cover 2, a second movable cover 3, and an opening and closing mechanism. The bottom of the housing 1 has at least three supporting sections, the top of the housing 1 has a first sand inlet, and the lower part of the side wall of the housing 1 has a sand outlet. The first movable cover 2 is installed at the first sand inlet to open or close it, and a second sand inlet is located in the middle of the first movable cover 2. The second movable cover 3 is installed at the second sand inlet to open or close it. The opening and closing mechanism is movably connected to the housing 1 to open or close the sand outlet. This structural design allows the fire sandbox to have multiple sand inlet methods and flexible sand outlet control. Multiple sand inlets facilitate sand replenishment operations at different levels, and the at least three supporting sections at the bottom improve the stability of the sandbox, enabling it to adapt to different placement environments and reducing the risk of the sandbox tipping over due to unstable support. The movable covers and opening and closing mechanism allow for quick access to fire sand when needed, and can effectively seal the sandbox when not in use, protecting the internal fire sand.

[0028] In a preferred embodiment, one side of the first movable cover 2 is rotatably connected to the housing 1 via a first rotating shaft 4, and the second movable cover 3 is rotatably connected to the first movable cover 2 via a second rotating shaft 5. This rotatable connection allows the first and second movable cover 2 to be opened and closed flexibly, making operation convenient. When sand is being introduced, the first movable cover 2 or only the second movable cover 3 can be opened depending on the actual situation, enhancing operational flexibility. Simultaneously, the stable rotating shaft connection ensures the reliability of the cover during long-term use, reducing the possibility of jamming or damage.

[0029] In a preferred embodiment, the periphery of the first movable cover 2 extends beyond the edge of the top opening of the box 1 to form an eaves structure. The eaves structure can effectively block rainwater, dust and other debris from falling directly into the box 1, preventing the fire sand from getting damp and dusty, ensuring the quality and performance of the fire sand in the box, extending the effective use time of the fire sand, and reducing the damage caused to the inside of the box 1 by impurities entering, thereby indirectly improving the overall service life of the sand box.

[0030] In a preferred embodiment, a first sealing strip and a second sealing strip are also included. The first sealing strip is provided at each contact point between the first movable cover 2 and the box body 1, and the second sealing strip is provided at each contact point between the second movable cover 3 and the first movable cover 2. The inclusion of the first and second sealing strips further improves the sealing performance of the sandbox. This better prevents sand, dust, and moisture from entering the box, enhancing the protection of the fire-fighting sand. Even in harsh weather conditions or dusty workplaces, the fire-fighting sand inside the sandbox remains in good condition, ensuring its effectiveness in fire suppression.

[0031] In a preferred embodiment, a baffle is also included. The baffle is disposed on the outer periphery of the second sand inlet, and the height of the baffle is higher than the top surface of the first movable cover plate 2. The baffle prevents fire sand from falling onto the top surface of the first movable cover plate 2 and outside the box 1 when sand is fed from the second sand inlet, thereby achieving precise sand feeding, avoiding unnecessary cleaning work, improving the efficiency and convenience of sand feeding, and keeping the area around the sand box clean.

[0032] In a preferred embodiment, the housing 1 is rectangular in shape and made of metal. Its interior is coated with an anti-rust coating. The rectangular shape facilitates manufacturing and placement, while the metal material ensures sufficient strength to withstand large quantities of fire sand. The internal anti-rust coating effectively prevents the inner wall of housing 1 from rusting due to prolonged contact with fire sand and moisture, extending its service life, reducing maintenance costs, and ensuring the stability and integrity of the housing 1 structure during long-term use.

[0033] In a preferred embodiment, the opening and closing mechanism includes a baffle 8, an upper slide rail, and a lower slide rail 7. The upper slide rail and lower slide rail 7 are respectively located above and below the sand outlet. The upper and lower sides of the baffle 8 are slidably connected to the upper slide rail and lower slide rail 7, respectively. This structural design allows the baffle 8 to slide smoothly up and down, facilitating the quick opening and closing of the sand outlet. In case of an emergency requiring fire sand, the baffle 8 can be quickly operated to expose the sand outlet, and the sand discharge rate can be adjusted by controlling the degree of sliding of the baffle 8 according to actual needs, improving the convenience and flexibility of sand discharge operation to adapt to different firefighting scenarios.

[0034] In a preferred embodiment, a first handle 9 is provided on one side of the baffle 8, a second handle 10 is provided on the first movable cover 2, and a third handle 11 is provided on the second movable cover 3. The handles facilitate the operator's operation of the baffle 8, the first movable cover 2, and the second movable cover 3. In emergencies, the handles allow the user to more easily and quickly grasp them for operation, improving efficiency and accuracy. Especially when hands are wet or in a state of panic, the handles facilitate the application of force to open or close the corresponding components, ensuring timely access to or containment of fire-fighting sand.

[0035] In a preferred embodiment, the support is four support legs 6, which are respectively installed at the four corners of the bottom of the box 1. These four support legs provide stable support for the box 1. Compared to other numbers or distributions of supports, this structure better distributes the weight of the box 1 and the fire-fighting sand inside, enhancing the stability of the sandbox and making it less prone to tipping over under various possible stress conditions, thus ensuring the reliability of the sandbox during daily storage and emergency use.

[0036] Example 2

[0037] This embodiment also provides a method for using an outdoor large-capacity fire sandbox as described in any of the above claims, including the following steps:

[0038] Installation and placement

[0039] Choose a suitable outdoor installation location and place the box 1 with four support legs 6 stably at the designated location, ensuring that the four support legs 6 are evenly stressed. Adjust the height of the support legs 6 or level the ground to ensure that the box 1 is in a horizontal and stable state. The four support legs 6 can effectively distribute the weight of the box 1 and the fire sand inside, ensuring that the sandbox is not easily tipped over under various circumstances.

[0040] Add fire sand

[0041] Large-scale addition: When a large amount of fire sand needs to be added, the operator grasps the second handle 10 on the first movable cover 2 and applies force to open the first movable cover 2 (at this time, the first movable cover 2 is opened by rotating the first pivot 4). Due to the eaves structure formed by the extension of the periphery of the first movable cover 2 and the sealing effect of the first sealing strip, it can effectively prevent debris from entering under normal conditions, and facilitates large-scale sand addition when opened. Afterwards, large tools such as loaders can be used to pour fire sand into the box 1 through the first sand inlet at the top of the box 1.

[0042] Small-scale addition: If only a small amount of sand is needed, the operator holds the third handle 11 on the second movable cover 3 to open the second movable cover 3 (the second movable cover 3 rotates relative to the first movable cover 2 via the second pivot 5). Using the second sand inlet, fire-fighting sand is loaded into the box 1 using a shovel or other small tools. The retaining edge on the outer perimeter of the second sand inlet makes the sand-filling process more precise and prevents fire-fighting sand from spilling. After adding sand, close the second movable cover 3 and the first movable cover 2, ensuring that the first and second sealing strips are properly sealed to prevent sand and moisture from entering the box.

[0043] Take fire sand

[0044] When a fire breaks out, firefighters quickly reach the location of the fire sandbox, grasp the first handle 9 on one side of the baffle 8, and apply force to slide the baffle 8 upwards along the upper and lower sliding rails 7 (the upper and lower sliding rails 7 are located above and below the sand outlet, respectively, to ensure smooth sliding of the baffle 8), exposing the sand outlet. The degree of sliding of the baffle 8 can be flexibly controlled according to the size of the fire and the actual firefighting needs to adjust the amount of sand discharged. For example, when the fire is large, the baffle 8 can be fully opened to achieve rapid and large-volume sand discharge; when the fire is small, the baffle 8 can be adjusted to a suitable intermediate opening position to precisely control the amount of sand discharged.

[0045] Post-use maintenance

[0046] After the fire is extinguished, firefighters slide the baffle 8 down along the slide rail to reset it and seal the sand outlet, preventing debris from entering the sand box. Regular inspections and maintenance of the sand box are necessary. Check the first and second sealing strips for damage; replace any worn strips immediately. Inspect the support legs 6 for sturdiness and for any looseness or damage. Check the upper and lower slide rails 7 for smooth operation, and ensure the baffle 8, first movable cover 2, and second movable cover 3 can rotate or slide normally; clean or repair any jamming. Also, check the integrity of the anti-rust coating inside the box 1; repair any peeling.
