DETAILED DESCRIPTION

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1-4 This utility model provides an embodiment of a water level control device for a fire-fighting water intake well, comprising: a control component 1, an intake well 10 externally disposed on the control component 1, the control component 1 including a first sealing plate 17 and a second sealing plate 2, a connecting rod 4 disposed at the upper end of the second sealing plate 2, a float control connector 5 disposed at one end of the connecting rod 4, a float connecting rod 6 disposed at the upper end of the float control connector 5, a float 7 disposed at one end of the float connecting rod 6, and a rod seat 15 disposed at the other end of the connecting rod 4, and the connecting rod 4 passes through the rod seat 15. The external screws are fixed to the second sealing plate 2. A connecting pipe 9 is provided at the upper end of the first sealing plate 17, and one end of the connecting pipe 9 is located inside the water intake well 10. The other end of the connecting pipe 9 is provided to the fire water tank 11, and the interior of the water intake well 10 is connected to the interior of the fire water tank 11 through the connecting pipe 9. A linkage mechanism 8 is provided at the connection between the connecting pipe 9 and the linkage rod 4. The water intake well 10 is buried underground, and the wellhead 13 is located above ground. The lower half of the fire water tank 11 is also buried underground. When the water intake well 10 is full, the buoyancy drives the float 7. The float moves vertically upwards, meaning the float 7 is half-submerged. The buoyancy of the float 7, through the float connecting rod 6 and the linkage rod 4, pulls the second sealing plate 2 upwards, bringing it into contact with the lower surface of the first sealing plate 17, thus achieving a seal and preventing the fire water tank 11 from replenishing water to the fire truck's intake. The size of the float 7 is required so that its buoyancy in the half-submerged state is greater than the total weight of the float connecting rod 6, the linkage rod 4, and the second sealing plate 2, and the water pressure generated on the second sealing plate 2 due to the water level difference between the fire water tank 11 and the fire truck's intake, to ensure that the water level... When the temperature rises, it provides greater buoyancy to tighten the second sealing plate 2 to achieve a seal. When the fire truck takes water, the buoyancy of the float 7 decreases due to the drop in the water level at the water intake. Since the water level in the fire water tank 11 is higher than the water level at the fire truck water intake, the second sealing plate 2 drops under the combined action of water pressure and the gravity of the second sealing plate 2, opening the connecting pipe 9. The fire water tank 11 replenishes water to the fire truck water intake, meeting the requirement of continuous water intake for the fire truck. This enables water level control at the fire truck water intake, making it possible to install a fire truck water intake in the semi-underground fire water tank 11.

[0022] Please see Figure 1 , 3 The lower surface of the first sealing plate 17 is provided with an embedded groove 12, and a rubber sealing ring 3 is embedded inside the embedded groove 12. When the second sealing plate 2 moves upward and contacts the lower surface of the first sealing plate 17, the connection sealing performance is improved by the rubber sealing ring 3.

[0023] Please seeFigure 1 , 4 The outer wall of the second sealing plate 2 is provided with a sealing flange 16, and the sealing flange 16 is welded and fixed to the second sealing plate 2, which improves the sealing range of the second sealing plate 2 and also facilitates the external fasteners of the second sealing plate 2 to maintain a continuous sealing state with the first sealing plate 17. The fasteners can be fixed according to actual needs, which improves flexibility.

[0024] Please see Figure 1 The top surface of the water intake well 10 is provided with a well opening 13, and a well cover 14 is provided at the upper end of the well opening 13 to seal and protect the water intake well 10.
