Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As fig. 1, do the utility model discloses a disaster-proof safety power distribution cabinet, including the cabinet body 1, the cabinet body 1 is gone up to articulate has the cabinet door. The cabinet body 1 bottom fixedly connected with base 12, the base 12 area is greater than the diapire of the cabinet body 1 to promote the support stability of the cabinet body 1 and ground, reduced the possibility that the cabinet body 1 emptys. A plurality of caulking grooves 121 parallel to the width direction of the base 12 are formed in the bottom surface of the base 12, and friction pads 122 are filled and bonded in the caulking grooves 121, so that the friction force between the base 12 and the ground is improved, the displacement of the cabinet body 1 and the ground during the earthquake is reduced, and the relative displacement of electrical elements in the cabinet body 1 and the ground is reduced.

As shown in fig. 2, triangular reinforcing rib plates 11 are fixedly connected between each side wall and the top wall and the bottom wall in the cabinet body 1 respectively, so that the overall structural strength of the cabinet body 1 is improved, and the possibility that the cabinet body 1 deforms to influence the integrity of the internal structure when the cabinet body 1 bears impact and pressure due to falling of heavy objects during an earthquake is reduced.

As shown in fig. 2, the sliding connection that has a plurality of connecting seats 6 along the symmetry of vertical direction on the relative both sides wall in the cabinet body 1, the equal fixedly connected with fixing base 61 in the upper and lower both sides that lie in every connecting seat 6 on the cabinet body 1 inside wall all is equipped with a vertical elastic component 5 between the fixing base 61 of connecting seat 6 and upper and lower both sides. All be equipped with horizontal elastic component 4 on the opposite one side of two connecting seats 6 that the symmetry set up on the relative lateral wall of cabinet body 1, be connected with mounting bracket 2 between two horizontal connecting pieces jointly.

As shown in fig. 3, the vertical elastic member 5 and the horizontal elastic member 4 have the same structure, and both include a sleeve 7 and a connecting rod 71, one end of the connecting rod 71 is slidably connected to the inner sidewall of the sleeve 7 along the axial direction of the sleeve 7, and one end of the connecting rod 71 located in the sleeve 7 is fixedly provided with a buffer spring 72. One end of the sleeve 7 far away from the extending part of the connecting rod 71 is sealed, and the buffer spring 72 is fixedly connected with the inner side of the sealed end. Therefore, when earthquake disasters occur, the earthquake force is absorbed through the horizontal elastic piece 4 and the vertical elastic piece 5, and the earthquake force transmitted to the mounting frame 2 is reduced.

Referring to fig. 4, a locking ring 73 is respectively provided at an end portion of each of the sleeves 7, which is located at an end portion of the link 71, the locking ring 73 is divided into a fixed half ring 731 and a movable half ring 732, the fixed half ring 731 is welded to an end portion of the sleeve 7, the movable half ring 732 and the fixed half ring 731 are respectively located at both sides of the link 71, a connecting lug 733 is respectively fixedly connected to both ends of the fixed half ring 731 and the movable half ring 732, a pressing bolt 734 is provided between the corresponding connecting lugs 733, and when a worker rotates the pressing bolt 734 to tightly hold the link 71 between the fixed plate element and the movable half ring 732, the sleeve 7 and the link 71 are relatively. Therefore, the shaking of each electrical component when the staff maintain and install the internal components of the power distribution cabinet is reduced, and the convenience is improved.

As shown in fig. 5, a plurality of buffer bases 21 are fixedly connected to the mounting frame 2, the connection groove 211 is formed in the side wall of the buffer base 21 away from the mounting frame 2, a plurality of connection springs 2111 are fixedly connected to the inner side wall of the connection groove 211, each connection spring 2111 is commonly connected to one connection block 221, the connection block 221 is fixedly connected to the mounting base 22 in the direction towards the notch of the connection groove 211, and the electrical components are all mounted on different mounting bases 22. When earthquake disaster takes place, horizontal elastic component 4 and vertical elastic component 5 absorb the seismic force at first, reduce the seismic force that conducts to on the mounting bracket 2, simultaneously through the setting of each connecting spring 2111, mount pad 22 and electrical components have the trend of keeping original motionless under inertial effect, when mounting bracket 2 takes place the drunkenness, connecting spring 2111 takes place elastic deformation, thereby delay the action that mount pad 22 moved thereupon, and then reduce the shake of mount pad 22, mount pad 22 downside fixedly connected with balancing weight 222 is with the holistic inertia of increase mount pad 22.

As shown in fig. 6, a cable stabilizer 3 is fixedly connected to one side of the mounting frame 2 away from the connection block 221 through a structural rod. 3 top sides of cable stabilizer and 2 top sides parallel and level of mounting bracket, and 3 length direction's of cable stabilizer both ends are all rotated and are connected with adjusting screw 32 along vertical direction setting, and common screw-thread fit has pressure strip 31 on two adjusting screw 32, and pressure strip 31 is on a parallel with the setting of mounting bracket 2. All seted up through-wire groove 33 on the lateral wall that pressure strip 31 and mounting bracket 2 are relative, the cable of being connected with electrical components passes through-wire groove 33 respectively, and when the cable was pressed from both sides tightly by cable steady rest 3 and clamp plate cooperation, should leave a small amount of allowances between cable steady rest 3 and mounting bracket 2, avoids the cable excessively tight.

The implementation principle of the embodiment is as follows: through the cooperation that sets up cable fastening clamp and pressure strip 31 with the cable press from both sides tightly, when reducing earthquake disaster and taking place, the one end that cable and electrical components are connected takes place to rock by a wide margin, leads to the link not hard up to cause electrical components and circuit bad contact to influence its normal condition of working. The horizontal elastic piece 4 and the vertical elastic piece 5 absorb the shock force, and the condition that the electrical components are directly damaged by shock is reduced. Through the arrangement of the connecting buffer seat 21, the displacement of the electrical components along with the mounting rack 2 is further reduced, so that the electrical components are better protected.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
