Description
Technical field
The present invention relates to a kind of water turbine, belong to the water conservancy equipment technical field.
Background technique
Water turbine is to be the transformation of energy of current the dynamic power machine of rotating mechanical energy.Modern water turbine great majority are installed in the water power plant, are used for driving generator for electricity generation.In the water power plant, the water in the upper pond is guided water turbine into through aqueduct, promotes the rotary wheel of water turbine rotation, drives generator for electricity generation.The water of finishing merit then passes through the tail water row of conduits downstream.Head is high more, flow is big more, and the output power of water turbine is also just big more.Reaction turbine is a kind of of water turbine, and it has obtained all over the world using widely with the energy conversion efficiency height.Various types of reaction turbines all are provided with water feed apparatus, and the water feed apparatus of large and medium-sized vertical shaft reaction turbine generally is made up of spiral case, fixed guide vane and movable guide vane.The effect of spiral case is to be evenly distributed to current around the runner.When head below 40 meters the time, the spiral case of water turbine reinforced concrete cast on-site commonly used forms; When head is higher than 40 meters, the then normal metal spiral case that adopts welding or block cast.In reaction turbine, current are full of whole runner channel, and all blade receives the effect of current simultaneously, so under same head, runner diameter is less than impulse turbine.Their peak efficiency also is higher than impulse turbine, but when load variations, the efficient of water turbine receives influence in various degree.Reaction turbine all is provided with draft tube, and its effect is: the kinetic energy that reclaims outlet of rotary wheel place current; Current row downstream; When the mounting point of runner was higher than the level of tail water, this potential energy is converted into pressure can be reclaimed.For the water turbine of the big flow of low water head, the outlet kinetic energy of runner is relatively large, and the recyclability of draft tube has appreciable impact to the efficient of water turbine.Owing to also have impurity such as silt in the water in river, can deposit in spiral case, thereby cause the decrease in efficiency of water turbine.Existing water turbine has only the automation protective system, when temperature and pressure is higher than dangerous values, can take protective measure, can not let the real-time working state of recognizing water turbine of staff, various running parameters.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: proposed a kind of simple in structurely, easy to use, can let the staff can recognize the water turbine of water turbine working state and various running parameters in real time.
Technical solution of the present invention is achieved in that a kind of water turbine, comprises the diversion pipeline, water spraying mechanism; Control mechanism, braking line, main frame; The automation protective system, said diversion pipeline links to each other with water spraying mechanism, and said control mechanism links to each other with water spraying mechanism and is used for the control brake pipeline; Said water spraying mechanism links to each other with main frame, and said automation protective system is used to protect whole system, it is characterized in that; Said water turbine also comprises wireless communication section, and said wireless communication section links to each other with the automation protective system, can the various parameters that the automation protective system is measured be sent on the distance host; Said wireless communication section adopts the ZigBee wireless communication module.
Further, said automation protective system is surrounded temperature transducer, pressure transducer and is shown the stream advertiser.
The invention has the beneficial effects as follows: owing to adopted wireless communication module, can the commander that sends to that the various parameters in the water turbine work are real-time hold, be convenient to the staff working state of water turbine is analyzed, this apparatus structure is simple, and is easy to use.
Description of drawings
Below in conjunction with accompanying drawing technological scheme of the present invention is described further:
Fig. 1 is a water turbine schematic representation of the present invention.
Wherein: 1 diversion pipeline; 2 water spraying mechanisms; 3 braking lines; 4 control mechanisms; 5 main frames; 6 automation protective system and wireless communication section.
Embodiment
Below in conjunction with accompanying drawing the present invention is described.
Water turbine as shown in Figure 1 comprises diversion pipeline 1, water spraying mechanism 2, control mechanism 4; Braking line 3, main frame 5, automation protective system 6, wireless communication section 6; Diversion pipeline 1 links to each other with water spraying mechanism 2, and control mechanism 4 links to each other with water spraying mechanism 2 and is used for control brake pipeline 3, and water spraying mechanism 2 links to each other with main frame 5; The automation protective system is used to protect whole system, prevents temperature overheating, and flow velocity is too fast.Wireless communication section adopts the ZigBee wireless communication module.On this water turbine temperature is installed, pressure, flow transducer can be with recording temperature in real time, and pressure and flow velocity signal are sent on the long-range main frame through wireless communication section, thereby make the working state of recognizing water turbine that the staff can be real-time.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
