Description
Technical Field
The utility model relates to a novel water pump turbine top cover drainage system.
Background
The water pumping and energy storage top cover drainage system has a great relation, and a trip can be caused if the water pumping and energy storage top cover drainage system is operated by mistake, and a plant can be flooded if special conditions are not operated. Therefore, a set of top cover drainage systems that operate reliably is critical; generally, a top cover drainage system consists of a plurality of water level floater switches which are all arranged on the inner wall of a top cover, but because the space in the top cover is narrow, the floaters are easy to block or mutually restrict and can not normally reflect the water level change; therefore, the drainage pump on the top cover can not normally start to drain water, the water level of the top cover continuously rises, and the potential safety hazard of high jump of the water level of the top cover and even flooding of a factory building exists; in addition, the internal condition of the top cover cannot be monitored through visual numerical values in real time, the water level change of the top cover and the abnormity of equipment cannot be mastered in real time, and the analysis and summary of the water level change trend of the top cover cannot be further performed.
SUMMERY OF THE UTILITY MODEL
In view of the defects of the prior art, the utility model aims to provide a novel pump turbine top cover drainage system which is reasonable in structure, safe and convenient.
In order to solve the technical problems, the technical scheme of the utility model is as follows: the utility model provides a novel pump turbine top cap drainage system, includes the top cap body, the bottom has set firmly the locating plate in the top cap body, vertical inserting on the locating plate is established and is fixed with the plastics pipe, has seted up a plurality of through-holes on this plastics pipe, the intraductal liquid level changer that is equipped with of plastics pipe, the parallel installation pipe that is equipped with of plastics pipe side, installation pipe set up a plurality of float liquid level switches along its vertical extending direction interval, this float liquid level and liquid level changer all with top cap body external display control appearance electric connection, this display control appearance is located hydraulic turbine terminal incasement.
Furthermore, the probe end of the liquid level transmitter is coaxially inserted into the plastic round pipe.
Furthermore, four float liquid level switches are arranged, and the four float liquid level switches are a pump stop float switch, a main pump start float switch, a standby pump start float switch and an accident high water level jump float switch in sequence from low to high according to the installation height.
Compared with the prior art, the utility model has the following beneficial effects: the liquid level change signal is uploaded to a display controller in real time through a liquid level transmitter, so that the internal liquid level change can be monitored in real time, four floater liquid level switches can be used for sensing the water level of a top cover of the water turbine, and when the detected water level is too high, the water turbine is started to be stopped quickly; therefore, the high water level in the top cover caused by the failure of the float switch can be effectively avoided, so that accidents such as factory flooding and the like are avoided, namely, the shutdown can be controlled by the liquid level transmitter and the display controller even if the float switch fails; this novel pump turbine top cap drainage system simple structure, it is safe convenient more.
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Detailed Description
In order to make the aforementioned and other features and advantages of the utility model more comprehensible, embodiments accompanied with figures are described in detail below.
As shown in fig. 1-4, a novel pump turbine top cap drainage system, including top cap body 1, the bottom has set firmly locating plate 2 in the top cap body, the locating plate welds on the top cap body in order to guarantee plastics pipe installation stability, vertical the inserting on the locating plate is established and is fixed with plastics pipe 3, has seted up a plurality of through-holes 4 on this plastics pipe, the intraductal liquid level transmitter 5 that is equipped with of plastics pipe, the parallel installation pipe 6 that is equipped with of plastics pipe side, installation pipe set up a plurality of float liquid level switches 7 along its vertical extending direction interval, this float liquid level and liquid level transmitter all with top cap body outside display control appearance 8 electric connection, this display control appearance is located hydraulic turbine terminal box 9.
In the embodiment of the utility model, the probe end of the liquid level transmitter is coaxially inserted in the plastic round pipe, so that jamming is avoided.
In the embodiment of the utility model, four float liquid level switches are arranged, and the four float liquid level switches are a pump-stopping float switch 10 (model number 461SN, height 8cm), a main pump starting float switch 11 (model number 462SN, height 15cm), a standby pump starting float switch 12 (model number 463SN, height 22cm) and an accident high-water-level jump float switch 13 (model number 464SN, height 29cm) in sequence from low to high according to the installation height.
The working principle of the embodiment of the utility model is as follows: when the liquid level sensor is used, a water level change signal is uploaded to the display control instrument in real time through the liquid level transmitter, so that the change of the internal liquid level is monitored in real time, the four floater liquid level switches can be used for sensing the water level of the top cover of the water turbine, and when the detected water level is overhigh, the liquid level sensor is started to stop rapidly; therefore, the water level in the top cover can be effectively prevented from being high due to the failure of the float switch, accidents such as plant flooding and the like are avoided, and the machine can be controlled to stop through the liquid level transmitter and the display controller even if the float switch fails.
