Abstract
The utility model relates to a controller is sealing device under water, it includes a seal box under water, a gland is connected on seal box upper portion under water, the seal box with set up a sealing member between the gland, the inside fixed mounting control board of seal box, a controller, this device is equipped with an inlet wire closed hole, the closed hole of being qualified for the next round of competitions, and the control cable of connecting the external control unit is got into by the inlet wire closed hole, with the control board carries out serial link to adopt the serial communication mode to carry out the signal transmission. The utility model has the characteristics of with low costs, convenient operation, signal performance are good, but the wide application is in numerical control fountain equipment.
Description
Technical field
The present invention relates to a kind of controller underwater sealing device, in particular to a kind of controller underwater sealing device that can realize serial with external control unit outside and communicate.
Background technology
In current existing numerical control fountain technology, owing to electric machine control device is without water-proof function, electric machine control device is often placed in distance motor watch-keeping cubicle far away. The cable of long distance can cause signal attenuation on the one hand, affects signal transmission stability, and outlet is more on the other hand, not only produces electromagnetic interference, also add material cost and cost of labor.
Summary of the invention
For the problems referred to above, it is an object of the invention to provide a kind of controller underwater sealing device, electric machine control device can be arranged near motor, greatly reduce controller to motor cable line length, effectively strengthen its digital control signal; Adopt serial communication to carry out signal transmission simultaneously, reduce cable consumption, reduce costs.
For achieving the above object, the present invention takes following technical scheme: the present invention comprises a underwater sealing box, and described underwater sealing box top connects a gland, arranges a sealing member between described seal box and described gland; Described seal box inside fixed installation one control card, a controller; This device is provided with an incoming seal hole, and one goes out wire seal hole, and the control cable connecting external control unit outside is entered by incoming seal hole, carries out connected in series with described control card, and adopts serial communication mode to carry out signal transmission. Control card is connected with controller, and outlet cable is by going out wire seal hole extraction, and is connected with motor.
Wherein, described controller can be stepper motor driver, motor servo driver, control power supply one or more.
The present invention is owing to taking above technical scheme, and it has the following advantages: 1, make controller can be arranged near motor, greatly reduces electric controller to motor cable line length, effectively strengthens its digital control signal. 2, carry out signal transmission by serial communication, reduce cable consumption, reduce costs. The present invention can be widely used in various numerical control fountain equipment.

Embodiment
Below in conjunction with drawings and Examples, the present invention is described in detail.
As shown in Figure 1, the present invention comprises a underwater sealing box 1, and described underwater sealing box 1 top connects a gland 2, arranges a sealing member 3 between described seal box 1 and described gland 2;Described seal box 1 inside fixed installation one control card 5, controller 6. This device is provided with an incoming seal hole 7, and goes out wire seal hole 8, and the control cable connecting external control unit outside is entered by incoming seal hole 7, carries out connected in series with described control card 5, and adopts serial communication mode to carry out signal transmission; Control card 5 is connected with controller 6, outlet cable by going out wire seal hole 8 draw, and be connected with motor.
Described controller 6 can be stepper motor driver, motor servo driver, control power supply one or more.
When the present invention works, control card 5, controller 6 being fixedly mounted on sealing box body 1 inside, the control cable connecting external control unit outside is entered by incoming seal hole 7, carries out connected in series with control card 5, and adopts serial communication mode to carry out signal transmission; After control card 5 is connected with controller 6, by going out, wire seal hole 8 passes in outlet, and is connected to motor. During the invention process, controller 6 can be installed in from the place close to motor, and signal attenuation is few, intensity height; Owing to adopting serial communication mode, it is necessary to when installing many motors control device, only need a main cable, save cable, reduce costs; When controller 6 goes wrong, repair or replace by dismounting gland 2.
The various embodiments described above are only for illustration of the present invention, and wherein the structure of each parts, mode of connection etc. all can change to some extent, and every equivalents of carrying out on the basis of technical solution of the present invention and improvement, all should not get rid of outside protection scope of the present invention.
Claims (2)
