Description

Technical Field

[0001] The invention relates to the technical field of outlet cabinets, and in particular to a high-voltage inlet and outlet cabinet device in power transmission. Background Art

[0002] During the use of the outlet cabinets in the power system, the cabinets are often connected in parallel to make the outlet cabinets safer and more stable. However, many outlet cabinets currently do not have connection devices, or the connection devices are inconvenient to operate or are relatively complicated, which increases the workload of the staff. In addition, the drawer-type outlet cabinet is a closed shell made of steel plates, and the electrical components of the incoming and outgoing line circuits are installed in removable drawers to form a functional unit that can complete a certain type of power supply task. At present, the drawer units of some drawer-type outlet cabinets use a one-side locking method, which is relatively unstable. When the user forgets to unlock and forcibly pulls the drawer unit outward, only one side is stressed, and the locking rod is easily damaged.

DETAILED DESCRIPTION

[0017] The present invention is further described below in conjunction with the accompanying drawings and embodiments: Embodiment: A high-voltage inlet and outlet cabinet device in power transmission, see Figure 1-Figure 8 , The present design includes a cabinet body 1, drawer slots 2 and drawers 3. The cabinet body 1 is a square structure, and a plurality of drawer slots 2 for placing drawers 3 are arranged at equal intervals along the vertical direction on the front wall thereof. Slide rails 21 are arranged on both sides of the bottom of the inner cavity of the drawer slots 2, and pulleys 31 that slide with the slide rails 21 are arranged under the two side walls of the drawer 3. By arranging the pulleys 31 and the slide rails 21, the drawer 3 can slide more smoothly and stably in the drawer slots 2.

[0018] The cabinet body 1 is provided with a cabinet connection mechanism 4 on the top, and the cabinet connection mechanism 4 includes a left corner plate 41, a right corner plate 42 and a connecting rod 43. The left corner plate 41 and the right corner plate 42 are respectively fixed to the left end and the right end of the top of the cabinet body 1. The side walls of the longitudinal plates 44 of the left corner plate 41 and the right corner plate 42 are provided with connecting holes 45 for the connecting rod 43 to pass through. One end of the connecting rod 43 is provided with a limiting round block 46, and the other end is provided with an automatic limiting mechanism. The longitudinal plates 41 and the right corner plates 42 of the adjacent cabinet bodies 1 are connected to each other. The plate 44 is then clamped by a limiting round block 46 and an automatic limiting mechanism. In this case, the cabinet bodies 1 of the two outlet cabinets are moved together. After the longitudinal plates 44 of the left corner plate 41 and the right corner plate 42 on the adjacent cabinet bodies 1 come into contact, the connecting rod 43 is passed through the connecting hole 45 on the longitudinal plate 44. The limiting round block 46 on the connecting rod 43 and the automatic limiting mechanism cooperate to clamp the two longitudinal plates 44. The operation is convenient and simple, and it is also easy to install and disassemble. The adjacent cabinet bodies 1 can be quickly connected in parallel, thereby improving the safety and stability of the outlet cabinet.

[0019] Furthermore, the automatic limiting mechanism includes a limiting member 47, a limiting groove 48 and a compression spring 49. The limiting groove 48 is arranged at the top of one end of the connecting rod 43 away from the limiting round block 46. The cross section of the limiting member 47 is the same as the cross section of the limiting groove 48. The longitudinal section of the limiting member 47 is a right-angled trapezoidal structure, and its cross-sectional width gradually decreases from one end close to the limiting round block 46 to the other end. A plurality of the compression springs 49 are connected between the lower surface of the limiting member 47 and the bottom of the inner cavity of the limiting groove 48. When the end of the connecting rod 43 is inserted into the connecting rod 43, the limiting member 47 is in a right-angled trapezoidal structure. Hole 45, the end of the limiting member 47 with a smaller width contacts the outer wall of the longitudinal plate 44, and the horizontal reverse thrust acts on the upper inclined surface of the limiting member 47, generating a partial downward thrust to gradually push the limiting member 47 into the limiting groove 48. When the automatic limiting mechanism passes through the connecting hole 45, the limiting member 47 is ejected due to the reset action of the compression spring 49, and the two longitudinal plates 44 can be quickly clamped by the limiting member 47 and the limiting round block 46; when disassembly is required, the staff presses the limiting member 47 downward to retract it into the limiting groove 48, and then pulls out the connecting rod 43 to complete the unlocking.

[0020] Furthermore, the distance between the limiting circular block 46 and the inner wall of the limiting member 47 is equal to the sum of the thicknesses of the two longitudinal plates 44, so that the connection is tighter and no axial displacement occurs during operation.

[0021] Further, the drawer 3 is a square structure with a hollow top opening composed of a front panel 32, side panels 33, a rear panel 34, and a bottom panel 35. The bottom panel 35 includes a front bottom panel 351 and a rear bottom panel 352. The two sides of the front bottom panel 351 are connected to the lower inner walls of the side panels. The front end of the front bottom panel is in contact with the lower inner wall of the front panel, and its rear end is connected to the front end of the rear bottom panel. The two sides of the rear bottom panel are connected to the lower inner walls of the side panels, and its rear end is connected to the lower inner wall of the rear panel. The pulley 31 is arranged below the rear ends of the outer walls of the two side panels 33. The cross-section of the slide rail 21 is a "C" - shaped structure with an opening facing the middle of the drawer slot 2.

[0022] Further, the slide rail 21 includes an upper cross - plate 211, vertical plates 212, and a lower cross - plate 213. The lower cross - plate 213 is fixed to both sides of the inner cavity bottom of the drawer slot 2, and the vertical plates 212 are fixed to the lower parts of the two side walls of the drawer slot 2. A notch 214 for the pulley 31 to insert is provided at the outer end of the upper cross - plate 211. A limiting platform 215 in the shape of a frustum of a square pyramid is provided on the outer end of the upper surface of the lower cross - plate 213. By providing the notch 214 on the upper cross - plate 211 and the limiting platform 215 at the front end of the lower cross - plate 213, when the drawer 3 is placed into the drawer slot 2, the pulley 31 is lifted up and bypassed the limiting platform 215 and put into the notch 214. After being placed, the drawer 3 can be placed horizontally and then slid into the inner end of the drawer slot 2 along the slide rail 21. When working normally, when the drawer 3 is pulled out, in the horizontal state, due to the limiting effect of the limiting platform 215, the drawer 3 will not be accidentally separated from the drawer slot 2, which can play a role in safety protection and improve the safety of work.

[0023] Furthermore, a locking mechanism 5 is provided at the bottom of the front bottom plate 351, and locking holes 22 for the two ends of the locking mechanism 5 to pass through are provided below the front end side walls of the side plates 33 on both sides and at the front end of the side walls of the vertical plates 212. The locking mechanism 5 comprises a left locking rod 51, a right locking rod 52, a rack 53, a gear 54, a driving bevel gear 55, a driven bevel gear 56, a driving shaft 57, a driven shaft 58 and a knob 59. A rack 53 meshing with the gear 54 is provided on the front side wall of the left locking rod 51, the bottom end of the driven shaft 58 is connected to the axis of the gear 54, and the top end thereof is connected to the axis of the driven bevel gear 56; the driving bevel gear 55 is meshed with the driven bevel gear 56, the outer end of the driving shaft 57 is connected to the inner wall of the rotating 59, and the inner end thereof passes through the front plate 1 and is axially connected to the driving bevel gear 55; The left locking rod 51 and the right locking rod 52 are fixed to the bottom of the front bottom plate 351 by a plurality of fixing brackets 6, and the fixing brackets 6 are provided with a slide groove 61 for the sliding of the left and right locking rods; the right end of the left locking rod 51 is connected to the left end of the right locking rod 52 by a transmission mechanism 7, and the transmission mechanism 7 drives the left locking rod 51 and the right locking rod 52 to move toward each other. In this case, the driving shaft 57, the driving bevel gear 55, the driven bevel gear 56, the driven shaft 58 and the gear 54 are rotated in sequence by rotating the knob 59, and the gear 54 drives the rack 53 and the left locking rod 51 to move to the right, and the left end of the left locking rod 51 is unlocked from the locking hole 22 on the side plate 33 and the vertical plate 212. At the same time, the right end of the left locking rod 51 drives the right locking rod 52 and the left locking rod 51 to move toward each other through the transmission mechanism 7, so that both are unlocked at the same time.

[0024] Furthermore, the right end of the left locking rod 51 is provided with a first inclined rod 511 inclined toward the rear end, and the end of the first inclined rod 511 is connected to a first limit block 512 along the horizontal direction; the left end of the right locking rod 52 is provided with a second inclined rod 521 inclined toward the front end, and the end of the second inclined rod 521 is connected to a second limit block 522 along the horizontal direction.

[0025] The transmission mechanism 7 includes a rotating block 71, a fixing bolt 72, a first transmission rod 73 and a second transmission rod 74. The rotating block 71 is axially provided with an axial hole for the fixing bolt 72 to pass through. The top end of the fixing bolt 72 passes through the axial hole and is connected to the bottom of the front bottom plate 351. The two ends of the side wall of the rotating block 71 are connected to the inner ends of the first transmission rod 73 and the second transmission rod 74; the bottoms of the first limit block 512 and the second limit block 522 are respectively provided with rectangular or waist-shaped connecting holes connected to the outer ends of the first transmission rod 73 and the ends of the second transmission rod 74. The outer ends of the first transmission rod 73 and the second transmission rod 74 are respectively connected to the two connecting holes through the rotating shaft (the width of the connecting hole is greater than the diameter of the rotating shaft, and allows the rotating shaft to rotate). The movable shaft moves in four directions of left and right, front and back in the connecting hole), and when the rotating block 71 drives the first transmission rod 73 and the second transmission rod 74 to rotate, the rotating shaft connected with the first transmission rod 73 and the second transmission rod 74 can be prompted to move relatively in the connecting hole, and the first limit block 512 and the second limit block 522 are driven to move axially; in this way, when the user rotates the knob 59 to drive the left locking rod 51 to move rightward, the first limit block 512 at the right end of the left locking rod 51 drives the outer end of the first transmission rod 73 to rotate counterclockwise around the fixing bolt 72, and the second transmission rod 74 follows the counterclockwise rotation, driving the second limit block 522 and the second oblique rod 521 to move to the left end, and the right end of the right locking rod 52 can be unlocked from the locking hole 22, thereby completing the unlocking of the drawer unit.

The main bracket 62 is a square structure, and the slide groove 61 is provided on the top thereof. The cross section of the slide groove 61 is the same as the cross section of the left locking rod 51. Square connecting plates 63 are provided above the two side walls of the main bracket 62. The connecting plates 63 are connected to the bottom of the front bottom plate 351 by bolts. The fixed bracket 6 can be stably fixed to the bottom of the front bottom plate 351 through the connecting plates 63 on both sides. By arranging the slide groove 61 on the main bracket 62, a limiting effect can be played, so that the left locking rod 51 and the right locking rod 52 can slide along the direction of the slide groove 61, so that the two can be accurately inserted into the locking hole 22 to lock the drawer unit.

[0027] Furthermore, both ends of the front bottom plate 351 are connected to the side plates 33 by connecting the side plates 353, and the rear end of the front bottom plate 351 is provided with a folding plate 354 integrally formed therewith, and the folding plate 354 and the front bottom plate 351 form an "L"-shaped structure; the rear end of the connecting plate 63 at the rear end is connected with an "L"-shaped angle plate 64, and the side wall of the folding plate 354 is provided with a square hole for the angle plate 64 to pass through; the front end of the rear bottom plate 352 is connected to the angle plate 64 by bolts, and the horizontal section of the angle plate 64 passes through the square hole on the vertical section of the folding plate 354, and the horizontal section of the angle plate 64 is provided with a bolt hole, so that the front end of the rear bottom plate 352 is conveniently connected to the angle plate 64 through the bolt hole, thereby increasing the connection strength between the front bottom plate 351 and the rear bottom plate 352.

[0028] Furthermore, a long square hole 513 is provided in the middle part of the left locking rod 51 along the horizontal direction, and a fixing rod 514 is connected to the bottom of the front bottom plate 351, and the top of the first fixing rod 514 can pass through the long square hole 513; the right end of the long square hole 513 is connected to the second fixing rod 515, and a tension spring 516 is connected between the bottom ends of the first fixing rod 514 and the second fixing rod 515. When the user turns the knob 59 to drive the left locking rod 51 to move to the right, since the first fixing rod 514 is fixed to the bottom of the front bottom plate 351 and does not move with the left locking rod 51, the second fixing rod 515 is fixed to the bottom of the left locking rod 51 and moves with the left locking rod 51 to the right, and the right end of the tension spring 516 is stretched to the right. When the user releases the knob 59, the left locking rod 51 and the right locking rod 52 can be automatically reset by the tension spring 516.

[0029] Specific working process: when it is necessary to unlock and take out the drawer 3 placed in the outlet cabinet, the rotating knob 59 drives the driving shaft 57, the driving bevel gear 55, the driven bevel gear 56, the driven shaft 58 and the gear 54 to rotate in sequence, and the gear 54 drives the rack 53 and the left locking rod 51 to move to the right, and the left end of the left locking rod 51 is unlocked from the locking hole 22.
