Description
Technical Field
[0001] The utility model relates to the technical field of fire-fighting facilities, in particular to an outdoor fire-fighting sand pool with a sliding roof. Background Art
[0002] The main hazardous materials involved in the polysilicon production process are chlorosilanes (dichlorosilane, trichlorosilane, and silicon tetrachloride). Dichlorosilane and trichlorosilane are at risk of combustion and explosion when exposed to heat sources and open flames. Dichlorosilane, trichlorosilane, and silicon tetrachloride can react with water, release heat when exposed to water, and generate hydrochloric acid smoke. Therefore, the fire extinguishing agents generally selected are: dry powder, dry sand, and carbon dioxide. The existing fire sand pool at the production site is generally a rectangular pool with an open top. The sand is directly piled inside the pool, and a steel pipe frame is built on the top and covered with a light color steel plate to prevent rain and snow, so as to prevent the dry sand from being wetted by rain and snow and becoming damp and waterlogged.
[0003] Due to the characteristics of chlorosilane, fire fighting sand must be kept dry at all times to prevent the moisture in the wet fire fighting sand from reacting with chlorosilane to decompose and release heat and generate hydrochloric acid smoke, which not only fails to extinguish the fire but also causes secondary hazards. However, the existing fixed-roof fire fighting sand pools are inconvenient when unloading and replenishing sand and drying sand. Utility Model Content

[0035] The working process of a sliding roof outdoor fire sand pool is as follows:
[0036] When unloading and replenishing sand, the dump truck reverses to the front side of the cofferdam 1, and the operator pushes the front cover plate 3 to fit close to the rear cover plate 4, and the roller 6 rolls toward the rear end of the slide rail groove 2 to reduce the friction resistance of the front cover plate 3 moving backward.
[0037] Moreover, when the front cover plate 3 is attached to the rear cover plate 4 backward, the upper port of the sand pit is completely opened, and the sand in the dump truck can smoothly enter the sand pit.
[0038] If the sand in the sand pool needs to be dried, the front cover plate 3 is fitted close to the rear cover plate 4, and the upper port of the sand pool is completely open, so that the sand can be dried efficiently and kept dry.
[0039] Normally, the roller 6 rolls to the front end of the slide rail groove 2, and the front cover plate 3 and the rear cover plate 4 are unfolded relative to the upper end of the sand pool to cover the upper end of the sand pool to prevent the sand from being exposed to rain.
[0040] In the technical solution of the utility model, the device is convenient for unloading sand from a truck and drying sand, and is easy to operate.
[0041] Specifically, the sum of the front and rear widths of the front cover 3 and the rear cover 4 is greater than the length of the slide rail groove 2, so that the front cover 3, the rear cover 4 and the slide rail groove 2 form a triangle, and the front and rear width of the front cover 3 is equal to the front and rear width of the rear cover 4. When the front cover 3 and the rear cover 4 are unfolded, the angle between the front cover 3 and the rear cover 4 reaches 120°.
[0042] Specifically, the front cover plate 3 and the rear cover plate 4 have the same structure, both comprising a color steel plate and a steel pipe frame, the color steel plate is fixedly welded to the steel pipe frame, and the front cover plate 3 and the rear cover plate 4 are connected together by hinges.
[0043] like Figure 1 and Figure 6As shown, in a specific embodiment, it also includes a limit pin, one side wall of the slide rail groove 2 is sequentially arranged with a plurality of first limit holes 7, and the other side wall of the slide rail groove 2 is sequentially arranged with a plurality of second limit holes 8, each of the first limit holes 7 corresponds to one of the second limit holes 8, and the limit pin is sequentially inserted into one of the first limit holes 7 and one of the second limit holes 8 to limit the position of the roller 6 in the slide rail groove 2.
[0044] In this embodiment, the operator can push the front cover plate 3 as needed to roll the roller 6 to the rear of a first limiting hole 7 and a second limiting hole 8, and then insert the limiting pin into the first limiting hole 7 and the second limiting hole 8 in sequence, so that the limiting pin can reach the front edge of the roller 6 to prevent the roller 6 from rolling forward by itself, thereby fixing the angle between the front cover plate 3 and the rear cover plate 4, and thus fixing the open area at the upper end of the sand pool.
[0045] like Figures 1 to 5 As shown, in a specific embodiment, a notch 9 is provided on the front side wall of the cofferdam 1 , and an arc-shaped water retaining platform 10 is provided on the ground of the notch 9 .
[0046] In this embodiment, specifically, when the operator needs to take fire-fighting sand, the front cover plate 3 can be made to fit close to the rear cover plate 4, and then the handcart can be pushed through the gap 9 to enter the sand pool to load sand; and the arc-shaped water retaining platform 10 can prevent external accumulated water from entering the sand pool.
[0047] like Figure 4 and Figure 5 As shown, in a specific embodiment, it also includes an L-shaped limit handle 11, one end of the L-shaped limit handle 11 is hinged to the front cover plate 3, and the other end of the L-shaped limit handle 11 is provided with a third limit hole 12, and the limit pin is inserted into the first limit hole 7, the third limit hole 12 and the second limit hole 8 in sequence.
[0048] Specifically, if the limit pin directly contacts the front edge of the roller 6, there is a possibility that the roller 6 runs over the limit pin. However, in the present embodiment, when the roller 6 rolls to a suitable position along the slide rail groove 2, the operator can rotate the L-shaped limit handle 11 forward so that the other end of the L-shaped limit handle 11 is embedded in the slide rail groove 2. At this time, the limit pin is inserted into the first limit hole 7, the third limit hole 12 and the second limit hole 8 in sequence, which can further prevent the roller 6 from rolling forward and further fix the angle between the front cover plate 3 and the rear cover plate 4.
[0049] like Figure 4 and Figure 7 As shown, in a specific embodiment, a waterproof component 13 is further included, and the waterproof component 13 covers the hinged position of the rear cover plate 4 and the front cover plate 3.
[0050] In this embodiment, specifically, the waterproof component 13 is made of rubber material, and is fixed to the front cover plate 3 or the rear cover plate 4 by rivets. When the front cover plate 3 and the rear cover plate 4 are unfolded, the waterproof component 13 covers the hinge position of the front cover plate 3 and the rear cover plate 4.
[0051] In a specific embodiment, the left side and the right side of the cover plate are respectively connected to the waterproof curtain.
[0052] In this embodiment, specifically, the waterproof curtain includes a non-woven fabric and a waterproof coating attached to the non-woven fabric, and the waterproof curtain is fixed to the left side and the right side of the cover plate by rivets.
[0053] As the angle between the front cover plate 3 and the rear cover plate 4 changes, the waterproof curtain itself undergoes appropriate deformation. When the angle between the front cover plate 3 and the rear cover plate 4 reaches the maximum, the waterproof curtain can cover the gap between the cover plate and the slide rail groove 2.
[0054] In a specific implementation, the height of the cofferdam 1 is 1.2 m, and the height of the arc-shaped water retaining platform 10 is 5 cm.
[0055] In this embodiment, specifically, the 1.2m high cofferdam 1 is lower than the height of the rear bucket of the dump truck, which is convenient for the dump truck to unload sand into the sand pool. The operator pushes the handcart over the 5cm arc-shaped water retaining platform 10, which is within human power and will not be too difficult. At the same time, the arc-shaped water retaining platform 10 also plays a role in blocking rainwater.
[0056] like Figure 4 and Figure 5 As shown, in a specific embodiment, a handle 14 is further included, and the handle 14 is fixedly connected to the front cover plate 3.
[0057] In this embodiment, specifically, the operator holds the handle 14 to facilitate pushing the front cover plate 3 to move forward and backward along the slide rail groove 2, thereby achieving the purpose of opening and closing the upper port of the sand pool.
[0058] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
