Abstract
The utility model relates to a motor-driven swimming pulling apparatus. A centrifugal pump is driven by a DC electric motor to spray and propel. Energy is provided by an enclosed type electric accumulator to pull human body to quickly swim in water, and the speed and the direction can be changed. The utility model is characterized in that the rotatory shaft (5) of a DC electric motor (4) in a housing (1) is mechanical coupling with the impeller (7) of a centrifugal pumps (6), the positive and negative poles of an electric accumulator (10) is connected with winding electric.
Description
The utility model relates to a kind of body-building play apparatus waterborne.Existing water recreation utensil most of environment waterborne or large-scale apparatus that need be specific as surfing, Wave Race etc., be difficult for popularizing.Change the bulky problem of having determined though existing a kind of gasoline engine is the trip device that leads of power, also have following shortcoming: 1. mechanical device complexity, easy break-down.2. the cost height is difficult for popularizing.3. noise is big.4. starting is inconvenient.5. toxic emission is arranged.
The purpose of this utility model is to provide a kind of volume little, and cost is low, safe and convenient to use, the trip device that leads waterborne of low noise and non-exhaust emission.
The method that the utility model is finished is: do an external form with plastics or metal and be streamlined, dc motor, centrifugal pump, enclosed type battery, control circuit board are installed in the seal casinghousing of with closure, housing.Housing can be bubbled through the water column after said apparatus is installed.The housing rear portion is equipped with two handles, on one of them handle switch is installed, in order to by-pass cock state and speed.Battery is supplied with the motor energy when leading the work of trip device, the impeller high speed rotating of motor drives centrifugal pump, water sucks from the water inlet of housing bottom, by water spout from housing bottom to back lower place high velocity jet, grab the people and just to draw human body when on handle, pinning switch and travel forward.When hand left handle, switch cut out automatically, led the trip device and quit work.Control circuit board is the power governor of a variable duty ratio, changes dutycycle by the switch gearing potentiometer on the handle, reaches the purpose of governing speed.
The utility model has the advantages that with dc motor and do the power that leads the trip device, simple in structure, efficient is high, noise is low, non-exhaust emission is as then effect is better with permanent magnet DC motor.The jet propulsion of centrifugal pump formula can not injure human body in water.Because leading the trip device is a buoyancy aid in water, Gu the people has safety guarantee in water, and can make the swimming instruction device.
Accompanying drawing 1 is a surface structure schematic diagram of the present utility model, and accompanying drawing 2 is the utility model internal structure cutaway view.
Most preferred embodiment of the present utility model this in conjunction with the accompanying drawings 1, accompanying drawing 2 is further described: lead trip device housing (1) and be the moulded plastic structure, form by housing (1) and seal cover, at housing (1) rear portion two handles (2) are installed, switch (3) is installed on one of them handle.Inner centrifugal pump (6), direct current generator (4), battery (10), the control circuit board (11) installed of housing (1).Wherein the water inlet (9) of centrifugal pump (6) is positioned at the bottom of housing (1), delivery port is the position, back partially, bottom that water spout (8) is positioned at housing (1), its water spout (8) to the inclination angle of the back lower place with respect to housing (1) when being horizontal level about about 30 °.It is preferable that dc motor (4) is installed on the top of centrifugal pump (6).The impeller (7) of rotating shaft (5) the mechanical couplings transmission centrifugal pump (6) of dc motor (4) directly is socketed in the impeller (7) of centrifugal pump (6) in the rotating shaft (5) of dc motor (4) in order to improve transmission efficiency in the present embodiment.Between the housing of rotating shaft (5) and centrifugal pump (6),, prevent that the water in the centrifugal pump (6) from entering housing (1) inside with the sealing shroud sealing.A water conservancy diversion rafter (12) is respectively arranged leading two of trip device housing (1) bottoms, reduce the eddy current of water and can protect intake flow-guiding mouth (13) and water spout (8) not to be broken.The water inlet flow-guiding mouth (13) of one U type is installed in the bottom of centrifugal pump water inlet (9), in order to improve feed water flow to.The positive and negative electrode of the winding of dc motor (4) and battery (10) is electrically connected.For controlling party is to control the power that on off state that leads the trip device and the duty of regulating control circuit board (11) recently change dc motor (4) by the switch (3) on the handle (2) and with the potentiometer of switch (3) interlock, reach control and lead trip device speed purpose in this embodiment.Switch (3) and control circuit board (11) are serially connected with between the winding of battery (10) electrode and dc motor (4).At the rear, top of leading trip device housing (1) light emitting diode working station indicator (14) is installed, the dump energy of trip device is led in prompting.Lead the charging plug (15) that trip device housing (1) rear portion is equipped with the band alignment pin, connecting the low-voltage direct end socket of external charge device.
When the trip device is led in use, two hold handle (2), pin switch (3), dc motor (4) drives centrifugal pump impeller (7) rotation at a high speed, water sucks from water inlet (9), by after the centrifugal pump supercharging from water spout (8) rear high velocity jet downwards, drive human body and advance, the trip device is led in swing can change direction of advance, and the pressing position that changes switch (3) can be regulated pace.
Claims (3)
1, a kind of electronic trip device that leads, comprise housing (1), handle (2), be located at the centrifugal pump (6) in the housing (1), it is characterized in that being located at the impeller (7) of rotating shaft (5) the mechanical couplings transmission centrifugal pump (6) of the dc motor (4) in the housing (1), the winding of the positive and negative electrode of battery (10) and dc motor (4) is electrically connected.
2, the electronic trip device that leads according to claim 1 is characterized in that the impeller (7) of centrifugal pump (6) directly is socketed in the rotating shaft (5) of dc motor (4).
3, the electronic trip device that leads according to claim 1 is characterized in that the winding of dc motor (4) and being electrically connected of positive and negative electrode of battery (10) are serially connected with switch (3) and the variable rotating-speed control circuit (11) of dutycycle in the loop.
