Abstract

A water turbine, belonging to a power generating device, comprises a housing and a movable impeller, a plurality of groups of rotating wheels are arranged in the housing, a rotating shaft is arranged at the center of each rotating wheel, two ends of the rotating shaft are fixed on a bearing seat at two sides of the housing, one end of the rotating shaft is provided with a shaft head gear, the shaft head gears of all rotating wheels are connected in series by a chain, a plurality of connecting pieces are arranged on the circumference edge of the rotating wheel to connect with the movable impeller, the movable impeller is attached on the rotating wheel, the distance between the housing at one forward flow side and the rotating wheel is larger than or equal to the length of the impeller, the distance between the housing at one contraflow side and the rotating wheel is larger than or equal to the thickness of the impeller. By flushing the movable impeller with rotating wheel type water, the waterpower is converted into a power pushing the fan, no power is needed, the hydrodynamic force utilization ratio is high, moreover, the installation is convenient and the occupation space is less, the equipment is durable, and operates safely and stably.

Description

A kind of water turbine

Technical field

The utility model belongs to power generation equipment, is meant a kind of water turbine of used for cooling tower.

Background technique

Fan blade in the tradition cooling tower is generally by driven by motor, need expend electric power, for energy-conservation, the claimant has developed a kind of hydrodynamic(al) blower fan, utilizes cooling tower to send the lift more than needed of water water pump, change hydro powered into, do not need power consumption, this hydrodynamic(al) blower fan is open in Chinese patent 2008201163114, and body one side of hydrodynamic(al) blower fan is equipped with chain shaft and sprocket wheel up and down, chain is provided with active leave board, and a transmission device that links to each other with chain rivet links to each other with fan blade.The hydrodynamic(al) blower fan of this structure is owing to used chain, and in running, the easy torsional buckling of chain forms resistance, and hydrodynamic force consumption is big, and in addition, chain is fragile, is not durable.

Summary of the invention

The utility model provides a kind of hydrodynamic force utilization ratio height, stable, durable and easy for installation, the little a kind of water turbine that takes up room just in order to overcome above-mentioned deficiency, and main the improvement is without chain and sprocket wheel, uses rotary-type water instead towards the active leave board device.

It specifically is to implement like this: a kind of water turbine, comprise shell, active leave board, it is characterized in that being provided with in the shell some groups of runners, rotating shaft is established at each runner center, the two ends of rotating shaft are fixed on the bearing support of shell both sides, rotating shaft one end is established shaft joint or shaft head gear, the shaft head gear of runner is connected by the chain polyphone, the runner circle edge is provided with some links and connects active leave board, described active leave board radian and runner paste identical, the shell of following current one side and the spacing of runner are slightly larger than or equal impeller length, and the shell of adverse current one side and the spacing of runner are slightly larger than or equal impeller thickness.Impeller is followed runner rotation, and when impeller moved in the same way by current in housing, impeller was under inertia and water impact, and impeller launches, and the impeller tail end pastes mutually with frame and do not wipe shell, has reduced the current waste, has improved mechanical efficiency.When impeller moves to opposite direction and makes counter-current operation, active leave board is moving along trackslipping, impeller is calm in wheel surface, because of active leave board and rotor periphery match, substantially only increased the thickness of impeller, reduced resistance to water-flow to greatest extent, the same and runner impeller surface applying of shell herein, reduced current and run off, blocked current and passed through through the gap.Impeller is transferred to cooling tower fan blade by runner shaft joint or shaft head gear through chain through the power that current promote the rotation generation.

The link of the some active leave boards that are provided with on the runner circle edge is arranged with in the runner circular surfaces, the back part of link and the rectangular shape of runner circular surfaces.When impeller is launched into the right angle, after forming impeller, zone, right angle, link rear portion supports, and force impeller not move to the rear portion, be fixed in square position, be more suitable for current and promote.

When equipment was erect installation, not enough as current inertia condition, impeller can not normally be opened, and can help impeller to eject and launch at impeller root and runner link place installing spring.

Be to reduce the resistance of impeller and current, be provided with baffle plate, when active impeller forwards this place to, under the stopping of baffle plate, suitablely trackslip movingly, make impeller calm easily in wheel surface at the shell front end of adverse current one side section start.

The utility model towards active leave board, converts waterpower to promote blower fan power by rotary-type water, not power consumption, hydrodynamic force utilization ratio height, and easy for installation, take up room for a short time, equipment is durable, safety and stability during operation.

Accompanying drawing is a structural representation of the present utility model.

Embodiment

Embodiment 1, a kind of water turbine, comprise shell 1, active leave board 2, be provided with some groups of runners 3 in the shell 1, rotating shaft 4 is established at each runner 3 center, the two ends of rotating shaft 4 are fixed on the bearing support of shell both sides, rotating shaft one end is provided with shaft head gear 5 in addition, and each shaft head gear 5 of organizing runner 3 is connected by chain 6 polyphones, and runner 3 circle edge are provided with some links 7 and connect active leave board 2, link 7 is arranged with in runner 3 circular surfaces, the back part of link 7 and the rectangular shape of runner 3 circular surfaces; Active leave board 2 radians and runner 3 paste identical, the shell 1 of following current one side is slightly larger than with the spacing of runner 3 or equals impeller length, the shell 1 of adverse current one side is slightly larger than with the spacing of runner 3 or equals impeller thickness, is provided with baffle plate 8 at shell 1 front end of adverse current one side section start.
