DETAILED DESCRIPTION

[0015] The utility model is further explained below.

[0016] The utility model provides a kind of fire-fighting pool, mainly for the fire-fighting water supply in cold region, including pool body 1, the pool body 1 includes pool side wall 11, pool bottom plate 12 and pool top plate 13, and the pool side wall 11 includes underground pool wall 112 and above-ground pool wall 111;The flow guide wall 2 is arranged in the pool body 1, and the flow guide wall 2 is spaced apart and is arranged in the pool side wall 11 of the left and right sides of pool body 1 to form the flow channel 21 of S shape, and the circulating water pump 3 that is connected with the inside of pool body 1 is further provided on the pool body 1, and the inlet pipe 31 of the circulating water pump 3 is connected with the terminal bottom of flow channel 21, and the outlet pipe 32 of the circulating water pump 3 is connected with the top of the start end of flow channel 21;The circulating water pump 3 is electrically connected with the control cabinet 4 for controlling the start-stop of circulating water pump 3.

[0017] As Figures 1-2As shown, the fire pool comprises a pool body 1, which is designed in a semi-underground manner, i.e. half of the pool is located underground and half of the pool is located above ground, and comprises a pool bottom plate 12, an underground pool wall 112 arranged underground, a pool top plate 13, and an above-ground pool wall 111 arranged above ground. In this way, compared with an above-ground fire pool, the design can reduce the land occupation and the amount of thermal insulation materials, and compared with a buried fire pool, the design can reduce the excavation amount and the engineering excavation risk, and is beneficial to the later operation and maintenance. A flow guide wall 2 is arranged in the pool body 1. Specifically, the flow guide wall 2 is arranged on the pool side wall 11 on the left and right sides of the pool body 1 at intervals, and divides the internal space of the pool body 1 into a continuous S-shaped water flow channel 21, so as to force the water flow to circulate along the water flow channel 21. A circulating water pump 3 is arranged on the pool body 1 and is in communication with the pool body 1. As shown in Figure 1 , the water inlet pipe 31 of the circulating water pump 3 is arranged at the terminal end of the S-shaped water flow channel 21, i.e. at B in Figure 1 , and the water inlet pipe 31 is arranged at the bottom of the terminal end B, i.e. the water inlet pipe 31 penetrates through the pool bottom plate 12 to extend into the fire pool, so that the circulating water pump 3 can suck water from the bottom of the fire pool. The water outlet pipe 32 of the circulating water pump 3 is arranged at the starting end A of the S-shaped water flow channel 21, i.e. at A in Figure 1 , and the water outlet pipe 32 is arranged at the top of the starting end A, i.e. the water outlet pipe 32 penetrates through the pool top plate 13 to extend into the fire pool, so that the circulating water pump 3 can inject water from the top of the fire pool, so as to ensure that the water in the fire pool can flow up when the circulating water pump 3 is started, and the water is circulated in an internal circulation manner without consumption of water resources. The internal space of the pool body 1 is divided into a continuous S-shaped water flow channel 21 by the flow guide wall 2, so that the water in the fire pool can only flow along the water flow channel 21, and the water in the entire fire pool is driven by the circulating water pump 3 to circulate, so as to avoid the formation of a static area of the water body in the corner or the edge, so that the water in the entire fire pool can keep flowing, effectively avoiding freezing of the water body, and the S-shaped water flow channel 21 controls the water flow cross-sectional size through the interval of the flow guide wall 2, in combination with the flow and head of the circulating water pump 3, so as to realize uniform coverage of the water flow on the entire pool. This design enables the circulating water pump 3 to drive the large-volume water body to flow with low energy consumption, avoids short flow or invalid circulation, saves energy consumption, significantly improves the overall efficiency of the anti-freezing system, and reduces the initial investment and operation and maintenance costs without large-scale earth excavation or high-energy-consumption electric heating facilities. At the same time, the physical anti-freezing mode of water flow avoids the electric heating system leakage hazard, and improves the safety. In addition, the continuous flow characteristics of the water flow in the S-shaped water flow channel 21 can prevent long-term static placement of the water body, reduce the accumulation of sediments and the reproduction of anaerobic microorganisms, and thus reduce the risk of water quality deterioration.

[0018] The flow rate of the circulating water pump 3 is 200 m 3 The flow rate of the circulating water pump 3 is 200 m 3 The flow rate of the circulating water pump 3 is 200 m 2 The water in the pool completes a full circulation in 20 hours, meeting the antifreeze requirement; the flow rate and head of the circulating water pump 3 can be selected according to the actual engineering requirements, and the water flow rate of the circulating water pump 3 is controlled at 0.1-0.3 m / s to avoid local retention of water in the fire pool, affecting the antifreeze effect; the spacing between the guide walls 2 can be calculated according to the water flow rate and the flow rate of the circulating water pump 3 to determine the spacing between the guide walls 2; in extremely cold areas, the spacing between the guide walls 2 can be reduced to increase the water flow rate and further enhance the antifreeze ability; in areas with relatively suitable temperature, the spacing can be appropriately widened to reduce the circulating energy consumption. The above-mentioned electrical connection with the control cabinet 4 can be signal connection or control line connection, and the control cabinet 4 can use existing controllers with displays.

[0019] To ensure the structural safety of the entire fire pool and prevent water from freezing when circulating along the water flow channel 21, the height of the guide wall 2 is the same as the height of the pool side wall 11, and the spacing between the two adjacent guide walls 2 is 0.8-2.0 m; the height of the guide wall 2 is designed to be the same as the height of the pool side wall 11, i.e. the height of the guide wall 2 is flush with the pool top plate 13, which not only guides the water flow but also serves as an internal support structure to share the water pressure on the pool side wall 11, improving the overall deformation resistance; the arrangement of the guide wall 2 can also reduce the structural damage of the semi-underground fire pool caused by soil pressure or frost heaving force, prolonging its service life; the spacing between the two adjacent guide walls is controlled between 0.8-2.0 m, which can meet the requirements of maintenance space and ensure that personnel can enter the water flow channel 21 for cleaning, equipment maintenance or leakage inspection; it can also ensure the width of the water flow channel 21, while limiting the maximum width of the water flow channel 21 to 2.0 m to avoid excessive width, which can cause local retention of water circulation and prevent the water from flowing completely along the water flow channel 21, thus failing to ensure the antifreeze effect of the water in the fire pool.
