Abstract
The utility model relates to an electric device's safety device, this electric device include the motor, for the cable and the confession of motor power supply the cable drum that the cable was coiled, safety device including the controlgear that can the remote control motor shuts down with place the cable drum in on be used for judging that the cable puts most alarm device, controlgear concatenates on motor contactor return circuit, a wireless transmitter communication connection of controlgear and distal end, alarm device is pressed by the cable on the cable drum, alarm device with controlgear communication connection, the device remotely controlled and automatic protection.
Description
Technical field
The utility model relates to a kind of security protection, especially a kind of safety device of electrical equipment.
Background technology
In industrial processes, due to the needs of actual conditions, the impulse stroke of an electrical equipment may be very long, such as borehole operation; As this kind equipment, need to be equipped with longer cable and extra security official to guarantee the safety of equipment operating, but find in process of production, this kind equipment has following defect: 1, cable is not because have stop means, often can there is cable and discharge equipment also in walking, thus the industrial accident causing cable to break; 2, equipment when walking care provider outside equipment, because equipment is very large, tunnel is little, equipment is again totally-enclosed, once cause danger, cannot notify that human pilot adopts remedial measures in time.
Utility model content
The purpose of this utility model is: for above-mentioned prior art Problems existing, propose a kind of can the safety device of electrical equipment of remote control and automatically protection.
In order to reach above object, the safety device of a kind of electrical equipment of the present utility model, the cable drum that this electrical equipment comprises motor, coils to the cable of feeding electric motors and the described cable of confession, safety device comprise can remote control motor stopping opertaing device and be placed on cable drum for judging the warning device that cable drains, opertaing device is serially connected on motor contactor loop, the first wireless signal transmitter communication connection of opertaing device and far-end; Warning device is pressed on described cable drum by cable, and warning device and opertaing device communicate to connect.
First wireless signal transmitter care provider on hand, presses hand-hold wireless transmitter when causing danger, equipment is stopped, and plays the effect of protection personnel; The wireless launcher of tape travel switch is arranged on the cable rolling dish of cable, and cable just in time pushes down travel switch when 1-2 encloses, and the travel switch action when being less than 1-2 circle, equipment stops, and plays the effect preventing cable from breaking.
Preferred version of the present utility model is:
Further, opertaing device is primarily of the normally closed contact switch of sequential concatenation on motor contactor loop and wireless signal receiver composition, and wireless signal receiver is connected with the first wireless signal transmitter paired communication; Cable drum connects a cylindric dish width primarily of two discs and forms, warning device comprises the limit switch and the second wireless signal transmitter that are mutually electrically connected, limit switch is located at dish subordinate list face, second wireless signal transmitter is placed in described dish width, and the spacing of limit switch and disc is not less than the diameter of unit cable.
Further, warning device has: the first state that limit switch is pressed on dish width by cable, limit switch is in off state, and the second state that cable leaves limit switch, limit switch is in channel status.
Further, be provided with on the surface of dish width the groove put for limit switch, when cable drum twists on dish width, limit switch bounces back in groove.
Further, rechargeable battery is provided with in the second wireless signal transmitter.
The utility model beneficial effect is: it is convenient, small and exquisite, quick, reliability is high, simple to operate, uses prospect extensive.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.

Fig. 2 is the package assembly structural representation of patent of the present invention;
Fig. 3 is the electrical diagram of patent of the present invention;
1. cable cable rolling dish; 2. cable; 3. the wireless launcher of tape travel switch; 4. tight guard's valve normally closed contact; The receiver of 5.24V Digiplex; 6. motor contactor; 7. motor.
Embodiment
Embodiment one
The safety device of the electrical equipment that the present embodiment provides, as shown in Figure 1, this device is made up of two parts, the left side: one is the receiver of 24V Digiplex of connecting in motor contactor loop, allows the receiver opertaing device motor of 24V Digiplex; The right: two is two transmitters, and one is hand-hold wireless transmitter, and another is the wireless launcher of tape travel switch.
Principle of work:
As shown in figures 1 and 3, when care provider finds danger, care provider presses hand-held transmitter, now the receiver 5 of 24V Digiplex receives signal, tight guard's valve work, makes circuit disconnect, motor contactor 6 dead electricity, motor 7 quits work, thus realizes the object of care provider's Long-distance Control.
The wireless launcher 3 of tape travel switch is arranged on cable drum 1 as shown in Figure 2 and Figure 3; when cable 2 is less than 3-4 circle; cable leaves the wireless launcher 3 of tape travel switch, makes the wireless launcher 3 of tape travel switch transmit signals on the receiver 5 of 24V Digiplex, when; after the receiver 5 of 24V Digiplex receives signal; inner relay work, makes circuit disconnect, motor contactor 6 dead electricity; motor 7 quits work, the object that the equipment that realizes is protected automatically.
It should be noted that, the word "front", "rear" used in describing above, "left", "right", "up" and "down" refer to the direction in width figure, and word " interior " and " outward " refer to the direction towards or away from particular elements geometric center respectively.Finally it should be noted that, above embodiment is only in order to illustrate the technical scheme of the utility model patent and non-limiting technical scheme, those of ordinary skill in the art is to be understood that, those are modified to the technical scheme of patent of the present invention or equivalent replacement, and do not depart from aim and the scope of the technical program, in the middle of the right that all should be encompassed in patent of the present invention.
