Abstract

The utility model relates to an automatic protection switch, particularly a control device is capable of automatically protecting the electrical equipment when the earthquake occurs. The utility model is characterized in that an earthquake sensing ball arranged on a horizontal holding arm and placed by a supporting seat receives earthquake signals, thereby, the horizontal holding arm generates the elastic change deformation due to losing the earthquake sensing ball. The automatic control of the electrical equipment can be realized through the loosening and the closing of contacts on the horizontal holding arm.

Description

Automatic earthquake controller for electrical equipment

The utility model relates to a kind of circuit Automatic Protection Switching, refers more particularly to the control device that can protect electric equipment when earthquake takes place automatically.

Up to the present still find no at home and can promptly and accurately accept seismic signal, when the earthquake earthquake intensity reaches specified numerical value, can cut off (connection) power supply simultaneously to realize reducing the power supply automatic control equipment of earthquake generation disaster.

The purpose of this utility model just provides a kind of for can guarantee the automatic switch of safety utilization of electric power when earthquake takes place.

The technical solution of the utility model is: the hollow ball that a hard solid sphere is housed in the utilization is placed on the rigid bearing for sense shake ball, size with ball and contact-making surface constitutes the sensitivity of accepting seismic signal, bearing is fixed on an end that is subjected on the horizontal trailing arm that elastic force influences, when its earthquake intensity takes place and reaches predetermined numerical value in earthquake, sense shake ball falls, and make trailing arm produce the elasticity variation because of losing sense shake ball, because on the horizontal trailing arm, respectively be provided with electric contact down, the contact of former closure is thrown off, the closing of contact of former separation, thus realization is to the automatic control of electric equipment.

The utility model is owing to adopted such scheme, can get rid of because of Artificial Control and be difficult to accurately grasp the earthquake effect earthquake intensity, it is off one's guard to set up defences for a long time, many artificial uncertain factors such as slow in reacting, when earthquake takes place, can reduce its disaster of bringing or avoid production is caused the economic loss that there is no need.

Below in conjunction with accompanying drawing the utility model is further described.

Accompanying drawing is a front view of the present utility model.

In the drawings, sense shake ball 16 is made up of hard hollow ball 2 and hard medicine ball 3, be contained in the hard medicine ball 3 in the hard hollow ball 2, the optional steel of its material, sense shake ball 16 relies on bearing 4 surely to stand in an end of horizontal trailing arm 6, the other end of horizontal trailing arm 6 is fixing by rotating fulcrum 10, sense shake tumbler bearing 4 contacts for cambered surface with sense shake ball 16, the size of its contact-making surface constitutes the sensitivity of accurately accepting earthquake intensity, contact-making surface is big, then makes the earthquake intensity of sense shake ball 16 actions big, otherwise, contact-making surface is little, and the earthquake intensity of sense shake ball 16 actions is just little.Below the plane of horizontal trailing arm 6, be provided with tension spring 8 near rotating fulcrum 10, middle part at horizontal trailing arm 6 respectively is provided with electric contact 13 up and down, lower contact 7 and adjustable upper contact 15 are corresponding respectively with fixedly, be compressed at the gravity of sense shake ball 16 and the leverage lower spring 8 of horizontal trailing arm 6, fixed contact 7 contacts with water-level contact 13, binding post 11 is by lead 9 and binding post 12 conductings, electric equipment is an operating state, at this moment, binding post 12 is released states with binding post 14, when earthquake takes place, its earthquake intensity reaches fortification intensity, the effect unstability that sense shake ball 16 is subjected to seismic force falls into ball-catching disc 5 from sense shake tumbler bearing 4, horizontal trailing arm 6 under the effect of spring 8 with horizontal trailing arm 6 jack-up, at this moment, separate with fixing lower contact 7 horizontal trailing arm contact 13, and contact with adjustable upper contact 15, at this moment, binding post 12 is conducting state with binding post 14, thereby connect lighting circuit or warning circuit work, and make electric equipment be off-state, realize running into ruinous earthquake and can cut off original circuit rapidly before coming, and the original dead circuit of conducting simultaneously.

In the utility model, the operating state of sense shake ball 16 can monitor that translucent cover 1 optional glass or other transparent material are made, and are fixed with ball-catching disc 5 in the lower end of translucent cover 1 by translucent cover 1.

The utility model is looked big the I of Control current and is used separately, also can be used with A.C. contactor.

Claims
