Description

Technical Field

[0001] This utility model relates to the technical field of heat exchange stations, and in particular to a water accumulation detection device for heat exchange stations. Background Technology

[0002] Heat exchange stations are the core facilities of urban centralized heating systems. During long-term operation, the internal equipment is prone to water accumulation due to pipe leaks, condensate buildup, and other reasons. If the water accumulation is not dealt with in time, it can lead to equipment corrosion, electrical short circuits, or even safety accidents.

[0003] Existing heat exchange station water accumulation detection devices, such as the automatic water leakage alarm device disclosed in utility model patent application number 202420107675.5, mainly include a detection box, a buckle, a fixing mechanism, a detection mechanism, and an audible and visual alarm. Two buckles are provided, positioned on one side of the detection box. The fixing mechanism is located between the buckles and the detection box to secure them. In use, the operator inserts the fixing post into the first limiting groove, causing the buckle and the detection box to clamp the pipe. The limiting block extends into the fixing groove, thereby fixing the buckle and the detection box through the cooperation between the limiting block and the side wall of the fixing groove. The detection box is then fixed to the pipe through the cooperation between the buckle and the detection box. When water leakage occurs at the connection point, the leaking water droplets can drip directly onto the leakage sensing line. When any part of the leakage sensing line comes into contact with water, the leakage sensing line will experience a situation similar to a short circuit. The sensor determines the leakage situation based on the change in the resistance of the leakage sensing line.

[0004] However, most existing water accumulation detection devices can only sound an alarm after detecting a leak, requiring staff to come and drain the water, which is very time-consuming. Moreover, the heat exchange station is relatively humid, and the use of induction wire alarm detection is prone to false triggers, affecting the staff's judgment. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a heat exchange station water accumulation detection device that not only uses a float ball and a photoelectric sensor to dual detect changes in liquid level, thus avoiding false alarms, but also can promptly drain excess water to prevent greater economic losses.

[0006] This utility model discloses a water accumulation detection device for a heat exchange station, comprising a detection box; it also includes an alarm mechanism, a blowing mechanism, a float mechanism, and a drainage mechanism. The alarm mechanism is installed on the detection box to detect the liquid level, the blowing mechanism is installed on the alarm mechanism to disperse water mist, the float mechanism is installed on the detection box to detect the liquid level, and the drainage mechanism is installed on the detection box to promptly drain the accumulated water. A pipe is fixed to the detection box, and a small amount of clean water is added to the detection box. The alarm mechanism, in conjunction with the float mechanism, detects the liquid level. The blowing mechanism promptly disperses the water mist on the surface of the alarm mechanism to avoid misjudgment. When the alarm mechanism detects a change in water level, it promptly issues an alarm to remind staff to inspect the site. When the liquid level rises to a certain height, the float mechanism triggers the drainage mechanism to start, promptly draining the accumulated water and preventing greater economic losses.

[0007] Preferably, the testing box includes a box body, two sets of support plates, and pipe clamps. The bottom of the box body is connected to the ground, and the inside of the box body is provided with a cavity. Both sets of support plates are installed on the box body, and two sets of pipe clamps are installed on the two sets of support plates respectively. The operator fills a small amount of clean water into the cavity of the box body, places the heat exchange pipes on the two sets of support plates, and uses bolts to fix the two sets of pipe clamps to the two sets of support plates, thereby fixing the heat exchange pipes.

[0008] Preferably, the alarm mechanism includes a crossbeam, a photoelectric sensor, a buzzer, and an alarm. The crossbeam is installed inside the cavity of the housing, the photoelectric sensor is installed on the crossbeam, the buzzer is installed on the housing, and the alarm is installed on the buzzer. The photoelectric sensor detects the liquid level in the cavity of the housing. When a liquid level change is detected, the buzzer and alarm are triggered to remind staff to come and check.

[0009] Preferably, the blowing mechanism includes a miniature air pump, an air supply pipe, and a high-pressure nozzle. The miniature air pump is mounted on a crossbeam, the air supply pipe is mounted on the miniature air pump, and the high-pressure nozzle is mounted on the air supply pipe and communicates with the inside of the air supply pipe. When the miniature air pump is started, it draws air and delivers it to the high-pressure nozzle through the air supply pipe. The high-pressure nozzle then sprays the air to disperse the water mist around the photoelectric sensor, thus preventing the water mist from affecting the detection effect of the photoelectric sensor.

[0010] Preferably, the float mechanism includes a limiting frame, a slide rail, a float, an electrode plate, and a receiver. The limiting frame is installed in the cavity of the housing and has a groove. The slide rail is slidably installed in the groove of the limiting frame. The top of the float is connected to the bottom of the slide rail, and the bottom of the electrode plate is connected to the top of the slide rail. The receiver is installed in the cavity of the housing. When the liquid level rises, the liquid level pushes the float to rise, and the float pushes the slide rail to rise along the groove of the limiting frame. When the electrode plate touches the receiver, the receiver activates the drainage mechanism to drain water via an electrical signal.

[0011] Preferably, the drainage mechanism includes a water pump, a suction pipe, a filter, and a drain pipe. The water pump is installed on the housing, the suction pipe is installed on the water pump, the filter is installed at the bottom of the cavity of the housing and communicates with the inside of the suction pipe, and the drain pipe is installed on the water pump. The receiver starts the water pump via an electrical signal. The water pump draws out the accumulated water from the cavity of the housing through the suction pipe, filters the accumulated water through the filter to prevent impurities from entering the water pump, and connects the drain pipe to the urban drainage pipe. The water pump discharges the accumulated water into the urban pipeline through the drain pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the pipe is fixed on the detection box, and a small amount of clean water is added to the detection box. The alarm mechanism works with the float mechanism to detect the liquid level. The blowing mechanism blows away the water mist on the surface of the alarm mechanism in time to avoid the alarm mechanism from making a misjudgment. When the alarm mechanism detects a change in water level, it will issue an alarm in time to remind the staff to come and check. When the liquid level rises to a certain height, the float mechanism triggers the drainage mechanism to start, and the accumulated water is discharged in time to avoid greater economic losses.
