Description
Technical field
The utility model relates to a kind of water turbine, belongs to the hydro-electric power generating 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 that current are evenly distributed to 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 is subjected to 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 is subjected to 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, can take protective measure when temperature and pressure is higher than dangerous values, can not allow the real-time working state of recognizing water turbine of staff, various running parameters.
The model utility content
The utility model purpose is at the deficiencies in the prior art, provide a kind of simple in structure, easy to use, can allow the staff can recognize the water turbine of water turbine working state and various running parameters in real time.
The technical solution of the utility model is:
Water turbine is by diversion pipeline, water spraying mechanism, control mechanism, braking line, main frame, automation protective system and wireless communication section; described diversion pipeline links to each other with water spraying mechanism; described control mechanism links to each other with water spraying mechanism and is used for the control brake pipeline; described water spraying mechanism links to each other with main frame; described automation protective system and wireless communication section combine, and wireless communication section can the various parameters that the automation protective system is measured be sent on the distance host.
Preferably, described automation protective system comprises temperature transducer, pressure transducer and shows the stream advertiser that described wireless communication section adopts the ZigBee wireless communication module.
The beneficial effects of the utility model are:
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
Fig. 1 is a hydraulic turbine structure schematic representation of the present utility model.
Wherein: 1, diversion pipeline; 2, water spraying mechanism; 3, braking line; 4, control mechanism; 5, main frame; 6, automation protective system and wireless communication section.
Embodiment
Water turbine as shown in Figure 1, comprise diversion pipeline 1, water spraying mechanism 2, control mechanism 4, braking line 3, main frame 5, automation protective system and wireless communication section 6, wherein: diversion pipeline 1 links to each other with water spraying mechanism 2, control mechanism 4 links to each other with water spraying mechanism 2 and is used for control brake pipeline 3, water spraying mechanism 2 links to each other with main frame 5, described automation protective system and wireless communication section combine, wireless communication section can the various parameters that the automation protective system is measured be sent on the distance host, the automation protective system is used to protect whole system, prevent temperature overheating, flow velocity is too fast; Wireless communication section adopts the ZigBee wireless communication module.The automation protective system comprises temperature transducer, pressure transducer and shows the stream advertiser; can be sent on the long-range main frame by wireless communication section recording temperature, pressure and flow velocity signal in real time, thereby make the working state of recognizing water turbine that the staff can be real-time.
Above embodiment only is the utility model a kind of mode of execution wherein, can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, all belong to protection domain of the present utility model.
