The support seat 4 is the base of the fire residue screening device, one of the side panels 3 is fixed on the support seat 4, the movable bar 301 and the other side panels 3 are rotatably arranged on the support seat 4, and the first frame 1 and the second frame 2 are respectively fixedly connected to different side panels 3. When the movable bar 301 is fixedly connected to the side panels 3 relative to the support seat 4, a fixed installation position can be provided for the first frame 1 and the second frame 2, a sub-screen is installed on the first frame, and a collecting member 14 is installed on the second frame.

[0041] At the same time, the movable bar 301 and the side panel 3 can also change states relative to the support seat 4, that is, first loosen the movable bar 301 or the side panel 3 relative to the support seat 4, and adjust the corresponding positions of the movable bar 301 and the side panel 4 based on the support seat 3, so that the fire residue screening device has two states: wherein, in the first state, at least one sub-screen is located above the collecting piece 14; and in the second state, at least one sub-screen is arranged parallel to the collecting piece.

[0042] Optionally, when the movable bar 301 and the side panel 3 are fixed relative to the support base 4, the movable bar 301 and / or the side panel 3 are fixedly connected to the support base 4 via a fixing assembly.

[0043] Reference Figure 1-Figure 6 The second frame 2 is arranged in parallel with any number of the first frame 1, the first frame 1 and the second frame 2 are respectively fixedly connected to different side panels 3, a sub-screen is installed on the first frame 1, and a collecting member 14 is installed on the second frame 2, any number of side panels 3 are always parallel to each other along the first direction, and any number of movable bars 301 are always parallel to each other along the second direction, and the side panels 3 and the movable bars 301 are hinged to each other, and the movable bars 301 can be pushed to rotate relative to the side panels 3 by applying an external force, so as to adjust the angle formed by the side panels 3 and the movable bars 301 to form a first state, a second state, and an nth state;

[0044] One of the first frames 1 is fixed on the top of the support base 4; the other first frames 1 and the second frames 2 rotate along with the movable bar 301 to adjust the relative position of the support base 4;

[0045] In the first state, the other first frame 1 and the second frame 2 are moved to the top of the fixed first frame 1, so that the sub-screens are all located above the collecting member 14; at this time, the fire residues pass through the sub-screens arranged vertically up and down in sequence under the action of gravity to achieve separation, and finally fall into the collecting member 14 at the bottom;

[0046] In the second state, all the first frames 1 and the second frames 2 are arranged horizontally; at this time, there are no other components above the sub-screens and collecting members 14 at any positions, which is convenient for the staff to operate.

[0047] The side wall of the support seat 4 is provided with a fixing component. After the movable bar 301 is adjusted in angle relative to the fixed side plate 3, the fixing component is used to clamp the movable bar 301 and the side plate 3 into one body so that the angle thereof can no longer be changed.

[0048] Example 2

[0049] Based on Example 1, refer to Figure 1-Figure 6 A fire residue screening device comprises two first frames 1 and a second frame 2, the front and rear sides of the first frame 1 and the second frame 2 are respectively fixed with side plates 3 by bolts, and the two first frames 1 are respectively fixed on Figure 1 The uppermost and middle side panels 3, the second frame 2 is fixed as follows Figure 1The lowermost side panel 3 has an inverted "L"-shaped structure, and the three side panels 3 on the same side are parallel to each other, and the two movable bars 301 on the same side are parallel to each other, and the left and right ends of the side panel 3 are hinged to the two movable bars 301 respectively. The middle side panel 3 among the three side panels 3 is horizontally arranged and fixed to the top of the support seat 4 by bolts, and the movable bar 301 rotates around the relatively fixed side panel 3 hinge. In addition, the upper and lower side panels 3 are always parallel to the middle side panel 3 and adjust their relative positions by following the rotation of the movable bar 301. A plurality of first ball head rods 5 are plugged into the tops of the two first frames 1, and the first guide bucket 6 is plugged into and matched with the first ball head rod 5. The inner wall of the first guide bucket 6 is clamped with a sub-screen, and the sub-screen is divided into a first sub-screen 7 and a second sub-screen 701, such as Figure 1 As shown, a first sub-screen 7 is provided in a first frame body 1 at the top, and a second sub-screen 701 is provided in another first frame body 1 at the bottom. The left and right inner walls of the first frame body 1 are fixed with first magnetic members 8 by bolts, and a support rod 9 is inserted between the two first magnetic members 8. The second magnetic member 10 is sleeved on the outer wall of the support rod 9 and slides linearly between the two first magnetic members 8 under the guidance of the support rod 9. A pad 11 is fixed to the bottom of the second magnetic member 10 by bolts, and the pad 11 is relatively located below the first sub-screen 7 / the second sub-screen 701 and is flush with each other. The top of the second frame 2 is fixed with a plurality of second ball rods 12 by bolts, and the second guide bucket 13 is plugged with the second ball rod 12. The design of plugging the first guide bucket 6 and the first ball rod 5 and the second guide bucket 13 and the second ball rod 12 facilitates the disassembly and assembly of the first guide bucket 6 and the second guide bucket 13 on the first frame 1, facilitates the removal of the sieving residue, facilitates the research of harmful substances in the fire residue, and ensures the operation of the operators. The inner wall of the second guide bucket 13 is clamped with a collecting piece 14;

[0050] like Figure 1 As shown, the movable bar 301 is hinged relative to the side plate 3 to form a first state, at which time the two first frames 1 are located directly above the second frame 2; at this time, the fire residues pass through the first sub-screen 7 and the second sub-screen 701 in sequence under the action of gravity and enter the collecting member 14.

[0051] like Figure 6 As shown, the movable bar 301 is hinged relative to the side plate 3 to form a second state. At this time, the two first frames 1 and the second frames 2 are located in the same horizontal plane; the two first frames 1 and the second frames 2 are flush with each other, so that the first sub-sieve 7, the second sub-sieve 701 and the collecting piece 14 are in the same horizontal state, so as to facilitate viewing of the residues in the first sub-sieve 7, the second sub-sieve 701 and the collecting piece 14.

[0052] The two groups of first frames 1 and second frames 2 are always kept parallel. Since one of the side panels 3 is always kept fixed relative to the support base 4, the corresponding first frame 1 is always arranged horizontally, so that the fire residues placed therein will not fall out.

[0053] After the fixing assembly is loosened, an external force is applied to push the two movable bars 301 to rotate relative to the fixed side panels 3. During this process, the other two side panels 3 follow the adjustment position.

[0054] The tops of the first guide bucket 6 and the second guide bucket 13 are respectively fixed with handles 15 by bolts, the bottoms of the first frame 1 and the second frame 2 are fixed with lower buckets 16 by bolts, and one side of the support seat 4 is fixed with a vibration motor 17 by bolts. The design of the vibration motor 17 can drive the first sub-screen 7 and the second sub-screen 701 to vibrate, thereby accelerating the screening of the residue. One side of the support seat 4 is respectively threadedly connected with a first adjusting screw 18 and a second adjusting screw 19, and the first adjusting screw 18 and the second adjusting screw 19 form a fixing assembly; one end of the first adjusting screw 18 and the second adjusting screw 19 is connected to the side plate 3 or the movable bar 301 abuts to achieve the fixation of the side panel 3 and the movable bar 301 relative to the support seat 4, so that the prismatic structure remains unchanged; the bottom of the support seat 4 is fixed with a bottom plate 20 by bolts, and a plurality of rubber pads 22 are bonded to the bottom of the bottom plate 20. The design of the rubber pads 22 can play a buffering role when the vibration motor 17 drives the entire device to vibrate, so as to avoid the bottom plate 20 from colliding with the ground, thereby ensuring the stability of the device. The upper surface of the bottom plate 20 is fixed with a plurality of counterweight blocks 21 by bolts. The design of the counterweight blocks 21 can increase the stability of the device during use and avoid the device from tipping over, thereby ensuring the practicability of the device.

[0055] The working principle of this embodiment is as follows: Figure 1As shown, when in use, first, the substation fire residues are placed on the first sub-sieve 7, and then the vibration motor 17 is started. Since the two middle side panels 3 and the support seat 4 are fixedly connected, the side panels 3 are rotatably connected to the movable bar 301, and the other side panels 3 are movably installed on the movable bar 301, and the side panels 3 are respectively connected to the first frame 1 and the second frame 2, the vibration motor 17 drives the support seat 4 to vibrate, so that the two first frames 1 and the second frame 2 vibrate at the same time. When the first frame 1 at the top vibrates, the residues on the first sub-sieve 7 of the top first frame 1 will pass through the mesh of the first sub-sieve 7 and fall onto the second sub-sieve 701 of the middle first frame 1, and the second sub-sieve 701 performs secondary screening on the residues. The sieved residues are gathered on the collecting piece 14, and the substation fire residues After the screening is completed, the two pads 11 are pushed respectively, so that the second magnetic member 10 will be disengaged from the two first magnetic members 8 and slide to one side along the support rod 9. When the second magnetic member 10 is adsorbed on the other two first magnetic members 8, the pad 11 is located at the bottom of the first sub-screen 7 and the second sub-screen 701, which is equivalent to closing the bottom opening of the first frame 1 with the pad 11, which can effectively prevent the fine residues on the first sub-screen 7 and the second sub-screen 701 from falling down. Subsequently, the first adjusting screw 18 is rotated to disengage the first adjusting screw 18 from the side plate 3, and then one of the movable bars 301 is flipped. At this time, the movable bar 301 drives the side plate 3 to flip, and then drives the first frame 1 and the second frame 2 between the two side plates 3 to flip, until the two first frames 1 and the second frame 2 are flush. Figure 6 As shown, the second adjusting screw 19 is then rotated so that one end of the second adjusting screw 19 is against one side of one of the movable bars 301. At this time, the residues on the first sub-screen 7, the second sub-screen 701 and the collecting member 14 can be checked, and the operator can hold the handle 15 to remove the first guide bucket 6 and the second guide bucket 13 respectively, and transfer the residues therein to the hazardous substance research department.

[0058] The working principle of this embodiment is as follows: when the device needs to be moved, the threaded rod 24 can be rotated to make the sliding plate 25 slide downward along the supporting column 26, and then the moving wheel 27 passes through the through opening 28 and contacts the ground, so as to facilitate the movement of the device. The overall structure is simple and easy to operate.
