Abstract
The utility model relates to a water level monitor to monitor water level of pressure fore-bay and reservoir in small-sized hydropower station, which comprises a monitoring panel in an equipment room, a monitoring panel for a bay probe (1) and a bay probe (1). Wherein, the monitoring panel for the bay probe is connected with the bay probe through a three-core feeder (2) composed of a power wire, a high-frequency signal wire and a low-frequency signal wire. A high level warning light and a low level warning light (L1 and L2), a high level warning buzzer and a low level warning buzzer (W1 and W2) are positioned on the monitoring panel. In addition, the bay probe (1) is inserted into a vertical anti-creep sleeve (3). A lower end of the bay probe (1) is provided with a heavy bob (4). A filter screen (5) and an earth wire (6) are arranged on a bottom of the anti-creep sleeve (3). The power wire, high-frequency signal wire and low-frequency signal wire of the three-core feeder on the bay probe are respectively connected with a metal buoy (7) and an upper and a lower contact strip (8 and 9). The utility model has the advantages of simple structure, easy operation and high practicality.
Description
Technical field
The utility model belongs to the monitoring water storage device, particularly can prevent the level monitoring device of small hydropower station forebay, reservoir depletion or spilling water.
Background technology
Small hydropower station in present stage all has forebay or reservoir, is used for the generating of supplying water of small power station's hydraulic turbine.In actual use, generally all be that the special messenger manages small hydropower station forebay, reservoir: when the water shortage in small hydropower station forebay, the reservoir, the staff will adjust load.When the water yield in small hydropower station forebay, the reservoir surpassed peak level, the staff just need open a sluice gate, and the staff all wants the field observation SEA LEVEL VARIATION in said process.Because the water yield of forebay, reservoir changes, existing mode is observed to measure to the staff on the one hand and is made troubles, and labor capacity is big.Sometimes also can cause on the other hand can not normal power generation.Many level detection technology such as ultrasound wave, isotope or the like maturation are arranged before water level controlling party appearance, but all fail to be extensive use of at civil area because of cost is too high.For low-cost detection method, as Chinese utility model patent 200420070008.7 disclosed a kind of " simple and easy water level alarm ", it comprises transparent housing, is installed in the battery in the outer cover, the kickboard that is positioned at the outer cover front end is connected with electric connecting sheet by connecting rod, pilot lamp, hummer and connect back one end and link to each other in the outer cover with the negative pole of battery in the outer cover, the other end is connected with electric connecting sheet, electric connecting sheet be positioned at the outer cover anode under.But this device, is not suitable for small hydropower station and effectively monitors water level away from machine room because whole device ducks in drink.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of simple in structure, need not staff's field observation, just can realize the remote level monitoring device that shows and report to the police automatically.
The technical solution of the utility model is: a kind of level monitoring device comprises supervision panel and pond probe in the machine room; Monitor to have between the probe of panel and pond and be connected by supply lines, high signal wire and three core feeder lines of low signal line combination; On the supervision panel, be provided with high and low water-level alarm lamp; High and low water-level alarm hummer, wherein, high water-level alarm lamp and high water-level alarm hummer also connect high signal wire in the three core feeder lines, and low-water level alarm lamp and low-water level alarm buzzer also connect low signal line in the three core feeder lines, and these end three core feeder lines connect the 220V power supply; Above-mentioned pond probe stretches in the vertical anticreep outer tube, lower end lift heavy hammer, and anticreep outer sleeve bottom is installed filter screen and ground wire; Supply lines, high signal wire and low signal line in the described pond sound end three core feeder lines is connected on metal float, the upper and lower contact; Metal float can be with the rising or the decline of the height of water level.
For the ease of turnaround of unit, the described supply lines of three core feeder lines of should holding connects the 220V power supply through master switch.
In order to prevent the circuit accidental short circuit, guarantee power supply safety, supply lines, high signal wire and the low signal line in the described three core feeder lines gone here and there fuse respectively.
Because small power station is arranged at the mountain area usually, it is inevitable that equipment is accepted the thunder and lightning intrusion.Therefore, the thunder gap of setting up defences in the described three core feeder lines.
In order to prevent that alarm buzzer from yowling, the influence operation also is serially connected with the chimes of doom gauge tap respectively on high and low water-level alarm hummer.
After adopting said structure, along with the water yield in forebay or the reservoir increases gradually, water level constantly raises and drives metal float and move upward, impelling upward, contact links to each other with power supply, connect low full level alarm circuit, pilot lamp is bright, hummer is rung, and the prompting staff in time opens a sluice gate flood discharge.Otherwise water level constantly descends and drives metal float and move downward, and impels down that contact links to each other with power supply, connects the low-water level warning circuit, and pilot lamp is bright, hummer is rung, and points out the staff in time to adjust load.
The utility model is owing to adopt said structure, and the staff just can carry out water level to forebay or reservoir and automatically monitor in machine room.Exempt the work workload of making an inspection tour back and forth, guaranteed normal generating water, avoided the spilling water waste.And simple in structure, easy to use, good practical effect.In addition, the utility model can also be used for other places that needs control water level, and very big promotional value is arranged.
