Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of substation fire protection, in particular to a water level control device for a substation fire protection water tank. Background Art
[0002] The fire protection water tank body is a man-made structure for storing fire protection water, which is an important supplementary means for natural water sources or municipal water supply pipe networks. The water in the dedicated fire protection water tank body is rarely used, so the water quality is prone to deterioration. Moreover, when designing the dedicated fire protection water tank body in the northern region, anti-freezing measures need to be considered, which increases the construction investment cost.
[0003] In the prior art, in order to reduce the cost and ensure the water quality, the fire protection water is often designed to share a water tank with domestic and industrial water. However, in terms of water level control, general equipment cannot achieve the purpose of automatically controlling the water level, and the observation of the water level mostly relies on a liquid level gauge. Once the liquid level gauge fails, it is difficult to detect the change in the water storage volume in time, which is easy to cause waste of water resources. If fire protection requires emergency water at this time, it will lead to a greater safety accident and cannot ensure the fire protection water tank body to play its role. Summary of the Invention
[0004] In view of this, the purpose of the utility model is to provide a water level control device for a substation fire protection water tank that can achieve real-time monitoring of the water level and timely drain water to control the water volume.
[0005] The utility model is implemented by the following method: A water level control device for a substation fire protection water tank includes a fire protection water tank body. An inlet pipe is connected to the upper end of the right side surface of the fire protection water tank body, an outlet pipe is connected to the lower end of the right side surface of the fire protection water tank body, an overflow member is connected to the lower end of the left side surface of the fire protection water tank body, a sleeve is arranged in the middle of the fire protection water tank body, a buoy is arranged in the sleeve, an infrared emitter is arranged on the inner top surface of the sleeve, strip-shaped openings are formed on the left and right side surfaces of the sleeve, extension blocks extend outward from the left and right side surfaces of the buoy, the extension blocks are embedded in the strip-shaped openings, and an infrared receiver is arranged on the upper surface of the buoy.
[0006] Further, the overflow member includes an overflow pipe. The overflow pipe is connected to the lower end of the left side surface of the fire protection water tank body. A fixed housing is arranged at the lower end of the left side surface of the fire protection water tank body. A telescopic cylinder is arranged in the fixed housing, and a closing plate for opening and closing the overflow pipe is arranged at the end of the telescopic rod of the telescopic cylinder.
[0007] The beneficial effects of the utility model are as follows: the utility model adds a buoy, an infrared transmitter, an infrared receiver and an overflow piece to the device, which can realize real-time monitoring of the water level in the fire water tank body. The water inlet pipe is used to supply water to the fire water tank body, so that the water in the fire water tank body keeps flowing. When the water inlet pipe is used to supply water to the fire water tank body, the rising water level drives the buoy to rise. Through the action of the infrared transmitter and the infrared receiver, the water level of the fire water tank body can be monitored. When the water level is too high, it can be drained through the overflow piece and the outlet pipe, so as to avoid overflow of the water level in the fire water tank body due to excessively high water level, thereby achieving the purpose of automatically controlling the water level. BRIEF DESCRIPTION OF THE DRAWINGS
