[0023] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0024] In this disclosure, unless otherwise stated, directional words such as "up", "down", and "vertical" are defined according to the direction of the water leakage monitoring system. Figure 1 In the drawing direction, “inside” and “outside” are defined according to the outline of the corresponding parts. In addition, when the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0025] See also Figure 1 and Figure 2 The present disclosure provides a water leakage monitoring system for a hydro-turbine generator air cooler. The air cooler is used to cool the hydro-turbine generator and is placed on top of a tray (not shown). The tray collects water from the air cooler in the event of a leak. The water leakage monitoring system can monitor the leak by collecting water in the tray. The water leakage monitoring system can include a tank 100 and a water level sensing mechanism 200. The tank 100 can be provided with a water inlet 111 and a water outlet 112. The water inlet 111 can be located in a sidewall of the tank 100 and can communicate with the tray via a pipeline (not shown). For example, the water inlet 111 can be located in a sidewall of the tank 100 near the bottom wall and ensured to be lower than the tray. The water level sensing mechanism 200 can be disposed within the tank 100 to sense the water level within the tank 100.

[0026] It can be understood that the water in the tray enters the tank 100 through the pipeline, the water level sensing mechanism 200 is arranged in the tank 100, and is used for sensing the amount of accumulated water in the tank 100. When the amount of accumulated water reaches a certain value, the water level sensing mechanism 200 will issue an alarm. After the user handles the water leakage problem of the air cooler, all the accumulated water in the tank 100 can be discharged from the tank 100 through the water outlet 112 arranged at the bottom wall of the tank 100, so as to avoid that part of the accumulated water forms flocculation due to "stagnation" in the tank 100, and further avoid that the flocculation causes false alarm of the water leakage monitoring system, thereby ensuring the reliability and stability of the water leakage monitoring system. Through the water leakage monitoring system, it can be ensured that the air cooler can reliably cool the hydraulic generator, and the use performance and service life of the hydraulic generator are ensured.

[0027] In an embodiment, referring to Figure 1 and Figure 2 , the top of the tank 100 can be provided with an opening 113, and the water level sensing mechanism 200 can include a sensing assembly 210 and a mounting seat 220. The mounting seat 220 can be arranged on the opening 113. If it is necessary to clean the scale in the tank 100, the user can detach the mounting seat 220 from the opening 113 to clean the scale in the tank 100. The sensing assembly 210 can be mounted on the mounting seat 220 and can extend into the tank 100 to sense the water level in the tank 100. When the amount of accumulated water in the tank reaches a certain value, the sensing assembly 210 issues an alarm.

[0028] Further, the diameter of the opening 113 can be 130 mm to 150 mm. For example, the diameter of the opening 113 can be 130 mm, 135 mm, 140 mm, 145 mm or 150 mm. The opening 113 is arranged to be 130 mm to 150 mm, which can facilitate the user to clean the inside of the tank 100.

[0029] In the embodiment, referring to Figure 1The tank body 100 can include a tank body 110 and a rim 120 connected to the top of the tank body 110. The water inlet 111 and the water outlet 112 are both provided on the tank body 110. The rim 120 can enclose the opening 113. The leak monitoring system can further include fasteners that can pass through the mounting seat 220 and the rim 120 to fix the mounting seat 220 to the rim 120. By using the fasteners, the mounting seat 220 and the rim 120 are detachably connected, so that the user can easily clean the inside of the tank body 100. When the tank body 100 is made of the acrylic material described below, the rim 120 can be made of metal material to facilitate the connection of the mounting seat 220 by bolts. Of course, it can be understood that in other embodiments, the rim 120 can also be made of the same material as the tank body 100, and the connection between the rim 120 and the mounting seat 220 can also be a double-headed stud and nut cooperation or other connection methods.

[0030] In an embodiment, referring to Figure 1 The sensing assembly 210 can include a sensing member 213, a floating ball 211, and a sliding rod 212. The top end of the sliding rod 212 and the sensing member 213 can be mounted on the mounting seat 220. The floating ball 211 can be sleeved on the sliding rod 212 and can be in sliding connection with the sliding rod 212. The floating ball 211 can be configured to slide along the sliding rod 212 under the action of buoyancy and to trigger the sensing member 213 to send an alarm signal when the floating ball 211 contacts the sensing member 213.

[0031] It can be understood that the water in the tray enters the tank body 100 through the pipeline. The water will make the floating ball 211 slide upward along the sliding rod 212. When the amount of water accumulated in the tank body 100 reaches a certain amount, the floating ball 211 will contact the sensing member 213 to trigger the sensing member 213 to send an alarm signal. After the user receives the alarm signal, he or she can come to deal with the water leakage problem of the air cooler.

[0032] The sensing member 213 can include a magnetic element and an alarm element. When the floating ball 211 magnetically connects with the magnetic element, the circuit of the magnetic element and the alarm element is in a conduction state, the alarm element is powered and sends an alarm signal. When the water accumulated in the tank body 100 is emptied, the floating ball 211 moves downward relative to the sliding rod 212 under the action of gravity, and the floating ball 211 and the magnetic element are no longer magnetically connected, and the circuit of the magnetic element and the alarm element is in a disconnected state.

[0033] In another embodiment, the sensing assembly 210 can be a capacitive water level sensor, a piezoresistive water level sensor, or an ultrasonic water level sensor. By providing the sensing assembly 210, the user can easily understand and master the water accumulation condition in the tank body 100.

[0034] In an embodiment, the tank body 100 can be made of transparent material, so as to facilitate the user to visually observe the condition inside the tank.

[0035] Further, the tank body 100 can be made of acrylic material. Acrylic is also called organic glass, which has crystal-like transparency, and the light transmittance is above 92%, the light is soft, and the vision is clear. By setting the tank body 100 to be made of acrylic material, it is convenient for the user to visually observe the condition inside the tank.

[0036] The water leakage monitoring system in the embodiment of the present disclosure does not need to use an embedded temperature table, and can avoid the water in the tank body 100 from penetrating into the embedded temperature table to affect the detection.

[0037] In the embodiment, the tank body 100 can be provided with a water level scale line 300, so as to facilitate the user to visually observe the water accumulation amount inside the tank.

[0038] In an embodiment, the water outlet 112 can be arranged on the bottom wall of the tank body 100, and the bottom wall can be arranged in an arc shape. The water outlet 112 is arranged at the lowest position of the bottom wall, so that the accumulated water can be quickly discharged.

[0039] The preferred embodiments of the present disclosure are described in detail above in combination with the drawings, but the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept range of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all belong to the protection range of the present disclosure.

[0040] In addition, it should be noted that each specific technical feature described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combination manners.
