[0036] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other implementations obtained by ordinary technicians in this field without making any creative work are within the scope of protection of the present invention.

[0037] Example 1

[0038] A plug-and-play device for power grid terminals, see Figure 1 - Figure 3, including a mounting frame 1, on which two polished rods 11 are fixedly mounted, and a cable square tube 4 is slidably connected to the two polished rods 11, and a plurality of sockets 42 are fixedly mounted on the cable square tube 4, and the mounting frame 1 is slidably connected to a cabinet 3, and a wiring tube 31 is fixedly mounted on the bottom surface of the cabinet 3, and a connector 41 is connected to the top surface of the cable square tube 4 through a cable, and the connector 41 is plugged into the wiring tube 31, and the bottom of the mounting frame 1 is mounted on the ground of the basement by bolts. After the cabinet 3 is connected to the power grid, power is supplied, and the main cable inside the cabinet 3 is provided with a certain expansion margin. When the cabinet 3 moves upward, the main cable connecting the cabinet 3 to the power grid can be pulled outward by the power grid, so that the cabinet 3 can move upward normally. After the wiring tube 31 is docked with the connector 41, the plurality of sockets 42 on the cable square tube 4 are energized, and the user can plug the electrical equipment into the socket 42. When the water level rises to the floating block 51, the floating block 51 floats up by utilizing the buoyancy force. The cabinet 3 and the wiring square tube 4 are both made of lightweight materials. When the floating block 51 floats up, it can drive the wiring square tube 4 to move up, and the wiring square tube 4 drives the cabinet 3 to move up through the two connecting columns 32 (such as Figure 2 As shown), the cabinet 3 and the cable square tube 4 can always be kept above the water level to prevent the accumulated water from submerging the cabinet 3 and the cable square tube 4, which may cause damage to the cabinet 3 and the cable square tube 4 and leakage. By setting the floating component 5, the floating block 51 can float up as the water level rises after the basement is flooded. When the floating block 51 floats up, it drives the cable square tube 4 and the cabinet 3 to float up, so that the cable square tube 4 and the cabinet 3 are always located above the water level, to prevent the accumulated water from submerging the cabinet 3 and the cable square tube 4, which may cause damage to the cabinet 3 and the cable square tube 4 and leakage.

[0039] For further information, see Figure 3 - Figure 5The cam 53 is provided with a plurality of springs, and the ends of the springs away from the cam 53 are fixedly connected to the inner wall of the sliding cover 53 (such as the inner wall of the sliding cover 53). Figure 4 As shown in FIG5 , when the two inclined rods 57 move away from the mounting frame 1 , the two rollers 58 are driven downward by the inclined sections, so that the two rollers 58 drive the connector 41 downward, thereby separating the connector 41 from the wiring tube 31 , thereby disconnecting the power supply between the wiring square tube 4 and the cabinet 3 . Through the cooperation of the inclined rods 57 and the rollers 58 , after the floating block 51 floats up, the connector 41 can be automatically disconnected from the wiring tube 31 , thereby disconnecting the power supply to the wiring square tube 4 and further reducing the possibility of leakage.

[0040] Further, see Figure 1 、 Figure 5 - Figure 7 The inner wall of the sliding cover 53 away from the cross bar 56 is provided with an inner groove 54 (such as Figure 5 As shown in FIG2 , an inner slide 55 is slidably connected to the inner groove 54. The inner slide 55 is provided with a plurality of circular holes. The plurality of circular holes of the inner slide 55 are respectively located between the plurality of sockets 42 and the plurality of square holes of the sliding cover 53. When the plug is inserted into the socket 42, the plug first passes through the square hole of the sliding cover 53, then passes through the circular hole of the inner slide 55, and then is inserted into the socket 42. The edge of the circular hole of the inner slide 55 is clamped between the socket 42 and the plug. Figure 6-Figure 7 As shown in the figure, when the sliding cover 53 moves in the direction away from the mounting frame 1, the inner slide 55 in the sliding cover 53 moves in the direction away from the socket 42, so that the inner slide 55 pulls out the plug from the socket 42 through the edge of the circular hole, so that the plugs plugged in the socket 42 can be automatically pulled out when the float 51 floats up, thereby disconnecting the electrical equipment from the multiple sockets 42. By setting the inner slide 55, after the float 51 floats up, the inner slide 55 can pull out all the plugs on the multiple sockets 42, so that all the plugs plugged in the sockets 42 fall off, disconnecting the electrical equipment from the socket 42, and avoiding the floating block 51 from being pulled by the wires of the electrical equipment when floating up, affecting the normal upward movement of the wiring square tube 4, thereby causing water to enter the wiring square tube 4.

[0041] Also, see Figure 1 、 Figure 8 - Figure 11 , the sealing assembly 6 is used to seal the jacks on multiple sockets 42; the sealing assembly 6 includes a connecting frame 61, a sliding shaft 62 and a slot block 63. The connecting frame 61 is fixedly connected to the bottom surface of the inner slide 55, the connecting frame 61 passes through the sliding cover 53, the sliding shaft 62 is fixedly connected to the end of the connecting frame 61 away from the inner slide 55, the slot block 63 is connected to the top surface of the floating block 51, and a triangular slide is provided on the slot block 63. The sliding shaft 62 is slidably connected to the triangular slide of the slot block 63. The trajectory of the triangular slide is a right triangle, so the triangular slide of the slot block 63 has an oblique groove and two straight grooves, and the connection between the straight groove and the oblique groove is provided with a rounded corner (such as Figure 10 When the sliding shaft 62 moves to the right, it drives the inner slide plate 55 to move to the right in the inner groove 54 through the connecting frame 61. After the inner slide plate 55 moves to the right, the multiple circular holes on the inner slide plate 55 are misaligned with the socket 42, so that the part of the inner slide plate 55 without circular holes covers the socket 42, thereby completely blocking the socket 42 and preventing water from splashing into the socket 42. Through the setting of the sealing assembly 6, the inner slide plate 55 can move a distance in the inner groove 54 after the plug is disengaged from the socket 42, so that the circular hole is misaligned with the socket 42, and the inner slide plate 55 completely covers the socket 42, thereby preventing water from splashing into the socket 42.

[0042] In addition, see Figure 9 - Figure 11 The sealing assembly 6 further includes a plurality of sealing blocks 64, which are all slidably connected to the side of the inner slide 55 close to the socket 42. The plurality of sealing blocks 64 overlap with the sockets on the plurality of sockets 42 during movement. The sealing blocks 64 are made of elastic sealing material. After the sealing blocks 64 cover the sockets 42, even if water seeps into the inner groove 54, the sockets 42 can still be sealed and waterproofed (e.g. Figure 11When the inner slide 55 is moved into place, the plurality of sealing blocks 64 respectively cover and press against the plurality of sockets 42, thereby playing a sealing role and preventing water from seeping into the socket 42 after the inner groove 54 leaks, thereby further optimizing the waterproof effect.

[0043] It is worth noting that see Figure 1 、 Figure 12 - Figure 14 , the protection assembly 7 is used to block floating objects in the water to prevent them from colliding with the cable square tube 4; the protection assembly 7 includes two rotating arms 71, a protection rod 73 and two sets of sliding buckle blocks 76. The two rotating arms 71 are hinged to the bottom surface of the floating block 51, and the protection rod 73 is fixedly connected to the end of the two rotating arms 71 away from the floating block 51. The two rotating arms 71 are clamped between the floating block 51 and the bracket 2. The two sets of sliding buckle blocks 76 are connected to the floating block 51. A set of sliding buckle blocks 76 is set to two, and the two sliding buckle blocks 76 in the same group are set one above and one below (such as Figure 12 As shown in FIG, a torsion spring 72 is provided at the hinge of the rotating arm 71 and the floating block 51. The two rotating arms 71 contact the two slider blocks 76 located at the lower part of the two sets of slider blocks 76 during the movement. When the floating block 51 floats up, the rotating arm 71 rotates and pops out by the elastic force of the torsion spring 72. When the floating distance of the floating block 51 exceeds the length of the rotating arm 71, the rotating arm 71 rotates 180 degrees (i.e., from Figure 12 The state shown changes to Figure 14 When the two rotating arms 71 are rotated into place, the protective rod 73 is located in front of the float 51, which plays a role in blocking floating objects in the water and preventing floating objects in the water from colliding with the float 51, the sliding cover 53 and the cable tray square tube 4 when floating. Through the setting of the protective component 7, after the float 51 floats up, the two rotating arms 71 and the protective rod 73 can automatically flip and pop out, thereby protecting the area around the float 51 and preventing floating objects in the water from directly colliding with the float 51, the sliding cover 53 and the cable tray square tube 4, thereby playing a certain protective role.

[0044] It is worth mentioning that see Figure 1 、 Figure 12 - Figure 14 The protective assembly 7 also includes two sliding rods 74 and two limiting rods 77. The two sliding rods 74 are slidably connected to the top surface of the floating block 51. The top surfaces of the two sliding rods 74 are fixedly connected with the interference rods 75. The two interference rods 75 are both located on the movement trajectory of the sliding cover 53. The two limiting rods 77 are slidably connected to the inner walls of the two sets of sliding buckle blocks 76. The end of the sliding rod 74 away from the floating block 51 and the end of the limiting rod 77 away from the rotating arm 71 are respectively provided with right-angle ends, and the right-angle ends of the two limiting rods 77 are respectively overlapped. At the right-angled ends of the two slide bars 74, limit holes are provided on the rotating arm 71. The two limit rods 77 are respectively inserted into the limit holes on the two rotating arms 71 during movement. When the sliding cover 53 moves in the direction away from the mounting frame 1, the two abutting rods 75 drive the two slide bars 74 to move in the direction away from the mounting frame 1, so that the right-angled ends of the slide bars 74 are separated from the right-angled ends of the limit rods 77, so that the limit rods 77 fall down by their own gravity. When the two limit rods 77 fall down, they are respectively inserted into the limit holes on the two rotating arms 71 (such as Figure 14 The two limiting rods 77 are arranged so that after the two rotating arms 71 pop out, the two limiting rods 77 can be inserted into the limiting holes of the two rotating arms 71, thereby limiting the two rotating arms 71 and preventing the two rotating arms 71 from turning downward due to external forces, thereby increasing the stability of the two rotating arms 71 and improving the protection strength.

[0045] With the above structure, the working principle of this case is as follows: Figure 1The bottom of the mounting bracket 1 is fixed to the ground of the basement by bolts in the front, back, top, bottom, left and right directions. After the cabinet 3 is connected to the power grid, power is turned on. After the wiring tube 31 is docked with the connector 41, the multiple sockets 42 on the wiring square tube 4 are powered. The user can power on the electrical equipment by inserting the plug of the electrical equipment into the socket 42, achieving a plug-and-play effect. The bracket 2 is at a certain distance from the ground. The wiring square tube 4 and the cabinet 3 are both at a height suitable for operation. When the basement is flooded, as the water level in the basement rises, when the water level rises to the float 51, the float 51 floats up by buoyancy. The cabinet 3 and the wiring square tube 4 are both made of lightweight materials. Since the two light rods 11 are used for wiring, The cable square tube 4 is limited, and the cable square tube 4 can slide up and down on the two light rods 11, and the mounting frame 1 limits the cabinet 3, and the cabinet 3 can slide up and down on the mounting frame 1. Therefore, when the floating block 51 floats up, it can drive the cable square tube 4 to move up, and the cable square tube 4 drives the cabinet 3 to move up through the two connecting columns 32, so that the cabinet 3 and the cable square tube 4 can always be kept above the water level to avoid the cabinet 3 and the cable square tube 4 being submerged by accumulated water, thereby causing damage to the cabinet 3 and the cable square tube 4 and leakage. The main cable inside the cabinet 3 is provided with a certain expansion margin. When the cabinet 3 moves up, the main power connection between the cabinet 3 and the power grid The cable can be pulled outward by the power grid, so that the cabinet 3 can move up normally; when the cable square tube 4 moves up, the sliding cover 53 is driven to move up synchronously. When the sliding cover 53 starts to move up, the cross bar 56 on the sliding cover 53 contacts the inclined surface of the triangular block 52. The cross bar 56 slides along the inclined surface of the triangular block 52 during the upward movement, so that the cross bar 56 is subjected to the reverse thrust of the triangular block 52 while moving up and moves in the direction away from the mounting frame 1. The cross bar 56 drives the sliding cover 53 to move in the direction away from the mounting frame 1. When the sliding cover 53 moves, the two inclined bars 57 are driven to move synchronously. The connector 41 is inserted into the wiring tube 31 from bottom to top, so the connector 41 can slide downward in the wiring tube 31 and be pulled out. When the two oblique rods 57 move in the direction away from the mounting frame 1, the two rollers 58 are driven downward by the inclined section, so that the two rollers 58 drive the connector 41 downward, thereby separating the connector 41 from the wiring tube 31, thereby disconnecting the power supply between the wiring square tube 4 and the cabinet 3. Since the cabinet 3 is above the wiring square tube 4 and the wiring square tube 4 is close to the water surface, when the accumulated water generates waves or splashes, a small amount of water may splash onto the wiring square tube 4, thereby causing a small amount of water to enter the wiring square tube 4. When the wiring square tube 4 is powered off, the wiring square tube 4 can be prevented from being damaged by the small amount of water entering the wiring square tube 4 and causing a malfunction or leakage.When the plug of the device is inserted into the socket 42, the plug first passes through the square hole of the sliding cover 53, then passes through the round hole of the inner slide plate 55, and then is inserted into the socket of the socket 42. The edge of the round hole of the inner slide plate 55 is clamped between the socket 42 and the plug. Therefore, when the sliding cover 53 moves in the direction away from the mounting frame 1, the inner slide plate 55 in the sliding cover 53 moves in the direction away from the socket 42, so that the inner slide plate 55 pulls the plug out of the socket of the socket 42 through the edge of the round hole, so that the plugs inserted in the socket 42 can be automatically pulled out when the float block 51 floats up, thereby disconnecting the connection between the electrical equipment and the multiple sockets 42; through the setting of the floating component 5, the float block 51 can float up as the water level rises after the basement is flooded, and the float block 51 drives the cable square tube 4 and The cabinet 3 floats, keeping the cable tube 4 and the cabinet 3 above the water level. This prevents the cabinet 3 and the cable tube 4 from being submerged by accumulated water, which could damage them and cause electrical leakage. The inclined rod 57 and roller 58 cooperate to automatically disconnect the connector 41 from the wiring tube 31 after the float 51 floats, thereby disconnecting the cable tube 4 and further reducing the possibility of electrical leakage. The inner slide 55 allows the float 51 to pull out all the plugs from the sockets 42 after it floats, disconnecting the electrical equipment from the sockets 42, and preventing the float 51 from being pulled by the electrical equipment's wires when it floats, which could affect the normal upward movement of the cable tube 4 and cause water to enter the cable tube 4.

[0046] When the cross bar 56 is separated from the triangular block 52, the sliding cover 53 is reset by the elastic force of multiple springs. At this time, the plug has been pulled out, the connector 41 and the wiring tube 31 have also been disconnected, and the subsequent wiring square tube 4, the cabinet 3 and the sliding cover 53 move up normally. When the sliding cover 53 is reset, it moves in the direction close to the mounting frame 1. When the sliding cover 53 moves, the inner slide 55 also moves synchronously. When the inner slide 55 moves, it drives the connecting frame 61 to move synchronously. When the connecting frame 61 moves, it drives the sliding shaft 62 to move synchronously. When the sliding shaft 62 moves, it also slides in the triangular slide of the slot block 63. The trajectory of the triangular slide is a right triangle. Therefore, the triangular slide of the slot block 63 has an oblique groove and two straight grooves. The sliding shaft 62 When moving in the direction away from the mounting frame 1, it slides in the straight groove of the triangular slide. During this process, the slide shaft 62 does not drive the connecting frame 61 to move. When the slide shaft 62 slides to the connection between the straight groove and the oblique groove, since the connection between the straight groove and the oblique groove is provided with a rounded corner, the slide shaft 62 slides into the oblique groove along the rounded corner, so that the slide shaft 62 can slide in the oblique groove during subsequent sliding. In the process of the slide shaft 62 entering the oblique groove, it drives the connecting frame 61 to move a small distance to the right. When the inner slide plate 55 follows the sliding cover 53 to reset, the plug has been separated from the socket 42. The inner slide plate 55 drives the slide shaft 62 to move backward through the connecting frame 61. When the slide shaft 62 moves backward, it slides in the oblique groove of the slot block 63. The slide shaft 62 is subjected to the reverse thrust of the oblique groove and moves to the right. When the sliding shaft 62 moves to the right, it drives the connecting frame 61 to move to the right. When the connecting frame 61 moves to the right, it drives the inner slide plate 55 to move to the right in the inner groove 54. When the sliding cover 53 is reset, the sliding shaft 62 enters the other straight edge of the groove block 63 and stops moving. The user can then manually toggle the inner slide plate 55, the connecting frame 61 and the sliding shaft 62 to return to their original position. After the inner slide plate 55 moves to the right, the multiple round holes on the inner slide plate 55 are misaligned with the socket 42, so that the part of the inner slide plate 55 without round holes covers the socket 42, thereby completely blocking the socket 42 and preventing water from splashing into the socket 42. When the inner slide plate 55 moves to the right, it drives multiple sealing blocks 64 to move to the right. When the inner slide plate 55 moves to the right in place, the multiple sealing blocks 64 cover the multiple The plug hole of the socket 42 is covered by the sealing block 64, and the sealing block 64 is made of an elastic sealing material. After the sealing block 64 covers the plug hole of the socket 42, even if water seeps into the inner groove 54, the plug hole of the socket 42 can be sealed and waterproofed; when the sealing block 64 moves to the right, it drives the inclined block 65 to move to the right. The inclined surface of the inclined block 65 abuts against the right edge of the square hole of the sliding cover 53 during the right movement, so that the inclined block 65 is subjected to the reverse thrust of the square hole edge of the sliding cover 53 during the subsequent sliding process and moves in the direction close to the socket 42, so that the inclined block 65 can squeeze the sealing block 64. When the sealing block 64 covers the plug hole of the socket 42, the sealing block 64 is tightly pressed against the plug hole of the socket 42 due to the squeezing of the inclined block 65, thereby further improving the sealing effect;The sealing assembly 6 allows the inner slide 55 to move a certain distance within the inner groove 54 after the plug is removed from the socket 42, misaligning the circular hole with the socket 42. The inner slide 55 completely covers the socket 42, thereby preventing water from splashing into the socket 42. The sealing block 64 and the bevel block 65 cooperate to ensure that after the inner slide 55 moves into place, the multiple sealing blocks 64 respectively cover and abut the multiple sockets 42, providing a sealing effect, preventing water from seeping into the socket 42 after the inner groove 54 leaks, further improving the waterproof effect.

[0047] When installing the floating block 51, the two rotating arms 71 are bent so that the floating block 51 is pressed on the two rotating arms 71. The two rotating arms 71 are placed on the bracket 2 so that the two rotating arms 71 are located between the bracket 2 and the floating block 51. When the floating block 51 floats up, the rotating arms 71 rotate and pop out by the elastic force of the torsion spring 72. When the floating distance of the floating block 51 exceeds the length of the rotating arms 71, the rotating arms 71 rotate 180 degrees by the elastic force of the torsion spring 72 (as shown in FIG. Figure 14When the two rotating arms 71 rotate, the protective rod 73 rotates synchronously. When the two rotating arms 71 rotate into place, the protective rod 73 is located in front of the floating block 51, which plays a role in blocking floating objects in the water and preventing floating objects in the water from colliding with the floating block 51, the sliding cover 53 and the cable tray 4 when floating. When the rotating arms 71 flip over, the sliding cover 53 also moves away from the floating block 51. When the swivel arm 71 is turned over, the sliding cover 53 contacts the two interference rods 75 and drives the two sliding rods 74 to move away from the mounting frame 1 through the two interference rods 75. After the sliding rod 74 moves a certain distance, the right-angle end of the sliding rod 74 disengages from the right-angle end of the limiting rod 77, so that the limiting rod 77 falls down by its own gravity. When the two limiting rods 77 fall down, they are respectively inserted into the limiting holes on the two swivel arms 71, thereby achieving the effect of limiting the two swivel arms 71. When the locking cam 73 is in the unlocked position, the locking cam 73 is in the unlocked position, and the locking cam 73 is in the unlocked position, so that the locking cam 73 is locked and the locking cam 73 is locked. The guard bar 73 can automatically flip and pop out, thereby protecting the area around the float 51 and preventing floating objects in the water from directly colliding with the float 51, the sliding cover 53 and the cable tray square tube 4, thereby playing a certain protective role; through the setting of the two limiting rods 77, after the two rotating arms 71 pop out, the two limiting rods 77 can be inserted into the limiting holes of the two rotating arms 71, thereby limiting the two rotating arms 71 and preventing the two rotating arms 71 from flipping down due to external forces, thereby increasing the stability of the two rotating arms 71 and thus improving the protection strength.
