Description

Technical Field

[0001] The present invention relates to smart grid technology, in particular to an integrated control cabinet for a smart grid. Background Art

[0002] It is well known that the integrated control cabinet for smart grid is a key device in the smart grid system, which undertakes the important task of centralized monitoring, management and control of power equipment. This control cabinet realizes efficient management and control of power equipment by integrating and installing various control modules of the smart grid. It usually includes a cabinet body, in which an installation cavity is provided for installing various control modules, and a cabinet door is provided on the outside of the cabinet body for closing the cavity and sealing protection. In actual applications, in order to improve the utilization rate of the space in the cabinet body and facilitate the operation and maintenance of the control module, the integrated control cabinet often adopts a drawer structure, that is, the smart grid module is installed by sliding and plugging the integrated drawer in the cabinet body.

[0003] For example, the invention patent with application publication number CN116526350B and titled "An integrated control cabinet for smart grid" includes a cabinet, wherein a plurality of drawers are arranged in the cabinet, wherein the drawers are installed in the electrical installation cavity of the cabinet in a floating manner in an up-and-down arrangement, wherein different power grid modules are arranged in different drawers, and a gap cavity is formed between two adjacent drawers; and a plurality of movable electromagnetic shielding devices, wherein the movable electromagnetic shielding devices are arranged between two adjacent drawers, and the size of the gap cavity between adjacent drawers is adjusted by storing and retracting the movable electromagnetic shielding devices into the cabinet. The present invention uses the movable electromagnetic shielding device to reasonably utilize the gap between the drawers during inspection and maintenance, so that after the drawer is pulled out, a larger gap space is obtained at the top and bottom areas of the drawer, which facilitates the rotation of the entire drawer and the power grid module, so as to obtain a better field of view and different viewing angles, and is more conducive to maintenance and upgrading and maintenance and repair operations.

[0004] The disadvantage of the prior art is that when operating inside the control cabinet, the electromagnetic shielding layer remains in the cabinet when the drawer is pulled out, and the drawer is still kept in a horizontal position for operation. When operating inside a drawer with a higher height, the personnel must ensure that they are in a higher position than the drawer to operate, which is inconvenient to use. Summary of the invention

[0005] The purpose of the present invention is to provide an integrated control cabinet for a smart grid to solve the above-mentioned deficiencies in the prior art.

[0006] In order to achieve the above-mentioned object, the present invention provides the following technical solution: comprising: a cabinet, wherein a mounting cavity for mounting each control module of a smart grid is arranged in the cabinet, and a cabinet door for closing and sealing the cavity is arranged on the outside of the cabinet, an integrated drawer for mounting a smart grid module is slidably inserted in the cabinet, and an electromagnetic shielding layer for electromagnetic shielding between multiple integrated drawers is arranged on the surface of the integrated drawer;

[0007] The two sides of the integrated drawer are slidably inserted into the cabinet body through the drawer structure, and in the process of pulling the integrated drawer outward, the pulling power drives the rotation of the resistance block in the resistance structure through the transmission structure, and cooperates with the rotating structure to realize the height of the electromagnetic shielding layer being increased in the process of pulling the integrated drawer outward, and the electromagnetic shielding layer is rotated and opened from the surface of the integrated drawer, and at the same time, the limit structure releases the restriction on the tilting structure, and one end of the integrated drawer is tilted downward from the cabinet body, and the three functions are performed simultaneously to obtain a larger operating space in the integrated drawer.

[0008] As a further description of the above technical solution: a drawer structure, which realizes the random installation of the integrated drawer in the cabinet by inserting and pulling out the slide rails and two sets of sliders arranged on both sides of the bottom of the integrated drawer, realizes the integrated installation of the control unit module of the smart grid in the drawer, and improves the utilization rate of the space in the cabinet by installing the control unit module in a drawer-style.

[0009] The drawer structure includes an integrated drawer movably plugged into the cabinet and an electronic shielding layer rotatably installed on the surface of the integrated drawer. The bottom ends of both sides of the integrated drawer are equipped with a left slider and a right slider, which are slidably connected to the insertion and extraction slide rails opened on both sides of the cabinet.

[0010] As a further description of the above technical solution: a transmission structure is arranged in the insertion and extraction slide rail opened on the left side of the cabinet body. The power generated when the integrated drawer is pulled out drives the rotation of the resistance structure through the engagement between the rack and the gear and is transmitted to the rotating structure, thereby realizing the lifting and rotation of the electromagnetic shielding layer.

[0011] The transmission structure includes an inner slide rail opened in the pull-out slide rail on the left side of the cabinet. A rack is arranged at the bottom of the inner slide rail near the end of the cabinet opening. The rack is meshed and connected to the bottom of the gear. The gear is fixedly connected to one end of the transmission rod. The other end of the transmission rod passes through the left slide block and is rotatably inserted into the bottom of the integrated drawer and fixedly connected to one side of the resistance block arranged in the resistance structure.

[0012] As a further description of the above technical solution: the interference structure is installed on one side of the bottom end of the integrated drawer, and is used to connect the transmission structure and the rotating structure through an internally arranged interference block with a conical cross-section, so as to convert the horizontal inspection force of the integrated drawer into a vertical force to raise the height of the electromagnetic shielding layer, and then cooperate with the rotating structure to rotate the electromagnetic shielding layer.

[0013] The resistance structure includes a connecting rod fixedly connected to a corner of the bottom of the electromagnetic shielding layer. The bottom end of the connecting rod is rotatably inserted in the integrated drawer and passes through an adjustment sleeve arranged in the rotating structure. A resistance ball is arranged at the bottom end of the connecting rod. The resistance ball is slidably and resistively connected to the surface of the resistance block. A groove is opened inward at the highest point of the outward protrusion on the surface of the resistance block.

[0014] As a further description of the above technical solution: the rotating structure is installed in a corner of the integrated drawer and has an adjustment sleeve installed inside, which divides the vertical force converted by the resistance structure into two parts:

[0015] The first part maintains the vertical force to increase the height of the electromagnetic shielding layer;

[0016] The latter part converts the vertical force into circular motion force and provides an upward force to realize the rotation of the electromagnetic shielding layer on the surface of the integrated drawer, and can also increase the height during the rotation.

[0017] The rotating structure includes an adjusting sleeve fixedly installed in a corner of the integrated drawer, a connecting rod movably inserted in the adjusting sleeve, sliding plates rotatably installed on both sides of the middle section of the connecting rod, the sliding plates are slidably connected in the spiral groove and the vertical groove, and the spiral groove and the vertical groove are opened on the inner wall of the adjusting sleeve.

[0018] As a further description of the above technical solution: a limiting structure is arranged in the left slider and the right slider, and is used to provide limitations on the position and angle when the integrated drawer is inserted into the cabinet, and automatically releases the limitation after the integrated drawer is fully pulled out to achieve rotation and tilting of the integrated drawer.

[0019] The limiting structure includes a telescopic groove opened at the top of the left slider and the right slider, a telescopic rod and a trapezoidal plate being movably inserted in the telescopic groove, the trapezoidal plate being fixedly installed at the top of the telescopic rod, the bottom end of the telescopic rod being inserted at the top of the rotating groove and fixedly connected with a resistance ring, the bottom surface of the resistance ring being slidably and resistively connected to the top of the limiting rod and being fitted to the surface of the tilting rod, the bottom end of the limiting rod being movably inserted in the tilting rod through a limiting spring, and the top end of the limiting rod being slidably connected to the limiting groove opened on the inner side wall of the rotating groove, and the two ends of the top of the resistance ring being connected to the two side walls of the bottom end of the telescopic groove through a reset spring.

[0020] As a further description of the above technical solution: the tilting structure realizes tilting of the integrated drawer at a certain angle after the tilting rods arranged on both sides of the bottom end of the integrated drawer lose the restriction of the limiting structure, thereby increasing the operable space inside the integrated drawer.

[0021] The tilting structure comprises a rotation groove opened on the inner bottom end surface of the left slider and the right slider, a tilting rod is rotatably connected in the rotation groove, and the top end of the tilting rod is fixedly connected to the two sides of the bottom end of the integrated drawer.

[0022] As a further description of the above technical solution: the transmission rod is inserted into an arc-shaped movable groove at the position of the inner wall of the integrated drawer on one side of the bottom end of the integrated drawer, so that when the integrated drawer is fully pulled out and rotated and tilted, the transmission rod will slide in the movable groove without restricting the rotation and tilting of the integrated drawer.

[0023] As a further description of the above technical solution: after the limit rod is squeezed, the limit rod is squeezed to the top end to fit the surface of the tilting rod. At this time, when the integrated drawer is rotated downward through the spherical shape of the top end of the limit rod, the top end of the limit rod continues to be squeezed inward and contracted and slides in the limit groove. When the integrated drawer is tilted to the maximum tilt angle, the top end of the limit rod reaches the limit position of the limit groove, and the transmission rod also reaches the limit position of the top end of the movable groove.

[0024] In the above technical scheme, the present invention provides an integrated control cabinet for a smart grid, in which a downwardly protruding resistance plate arranged at the top of the opening of the plug-in slide rail will slide to the resistance plate position when the left and right slide blocks slide, and the resistance plate will slide against the surface of the trapezoidal plate to achieve the squeezing of the limiting structure, thereby achieving the tilting rotation of the integrated drawer by the tilting structure.

[0025] The present invention has the following beneficial effects:

[0026] 1. Triple functions are performed simultaneously: when the integrated drawer is pulled out, the lifting, rotation and tilting of the electromagnetic shielding layer and the drawer can be completed synchronously, which improves the convenience and efficiency of operation. After the integrated drawer is pulled out, the integrated drawer can be tilted at a certain angle synchronously, which is convenient for operation inside the integrated drawer.

[0027] 2.

DETAILED DESCRIPTION

[0047] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0048] See also Figure 1-Figure 14 The embodiment of the present invention provides a technical solution for an integrated control cabinet for a smart grid: comprising: a cabinet 1, wherein the cabinet 1 is provided with an installation cavity for installing each control module of the smart grid, and the cabinet 1 is provided with a cabinet door for closing and sealing the cavity, wherein an integrated drawer 2 for installing the smart grid module is slidably inserted in the cabinet 1, and an electromagnetic shielding layer 3 for electromagnetic shielding between multiple integrated drawers 2 is provided on the surface of the integrated drawer 2; the characteristics are:

[0049] The two sides of the integrated drawer 2 are slidably inserted in the cabinet body 1 through the drawer structure, and in the process of pulling the integrated drawer 2 outward, the pulling power drives the rotation of the resistance block 9 in the resistance structure through the transmission structure, and cooperates with the rotating structure to realize the height of the electromagnetic shielding layer 3 being increased in the process of pulling the integrated drawer 2 outward, and the electromagnetic shielding layer 3 is rotated and opened from the surface of the integrated drawer 2, and at the same time, the limit structure releases the restriction on the tilting structure, and the integrated drawer 2 is tilted downward at one end of the cabinet body 1, and the triple functions are performed simultaneously to obtain a larger operating space in the integrated drawer 2.

[0050] In another embodiment provided by the present invention, preferably, a drawer structure is used, which realizes the random installation of the integrated drawer 2 in the cabinet 1 by inserting and pulling out the slide rail 4 and two sets of sliding blocks arranged on both sides of the bottom of the integrated drawer 2, realizes the integrated installation of the control unit module of the smart grid in the drawer, and improves the utilization rate of the space in the cabinet 1 by installing the control unit module in a drawer-style.

[0051] The drawer structure includes an integrated drawer 2 movably inserted in the cabinet 1 and an electronic shielding layer rotatably installed on the surface of the integrated drawer 2. A left slider 5 and a right slider 6 are installed at the bottom ends of both sides of the integrated drawer 2 and are slidably connected to the insertion and extraction slide rails 4 opened on both sides of the cabinet 1.

[0052] In another embodiment provided by the present invention, a transmission structure is provided in the insertion and extraction slide rail 4 opened on the left side of the cabinet body 1. The power generated when the integrated drawer 2 is pulled out drives the rotation of the resistance structure through the engagement between the rack 13 and the gear 12 and is transmitted to the rotating structure, thereby realizing the lifting and rotation of the electromagnetic shielding layer 3.

[0053] The transmission structure includes an inner slide rail 18 opened in the insertion and withdrawal slide rail 4 on the left side of the cabinet 1. A rack 13 is arranged at the bottom of the inner slide rail 18 near the opening end of the cabinet 1. The rack 13 is meshed and connected to the bottom of the gear 12. The gear 12 is fixedly connected to one end of the transmission rod 10. The other end of the transmission rod 10 passes through the left slider 5 and is rotatably inserted into the bottom end of the integrated drawer 2 and is fixedly connected to one side of the resistance block 9 arranged in the resistance structure.

[0054] In another embodiment provided by the present invention, a resistance structure is installed on one side of the inner bottom end of the integrated drawer 2, and is used to connect the transmission structure and to resist the connected rotating structure through a resistance block 9 with a conical cross-section arranged inside, so as to convert the horizontal force of the integrated drawer 2 into a vertical force to lift the electromagnetic shielding layer 3, and then rotate the electromagnetic shielding layer 3 in cooperation with the rotating structure.

[0055] The resistance structure includes a connecting rod 8 fixedly connected to a bottom corner of the electromagnetic shielding layer 3. The bottom end of the connecting rod 8 is rotatably inserted into the integrated drawer 2 and passes through an adjustment sleeve 19 arranged in the rotating structure. A resistance ball 20 is arranged at the bottom end of the connecting rod 8. The resistance ball 20 is slidably and resistively connected to the surface of the resistance block 9. A groove 15 is opened inward at the highest point of the outward protrusion on the surface of the resistance block 9.

[0056] In another embodiment provided by the present invention, the rotating structure is installed in a corner of the integrated drawer 2 and an adjusting sleeve 19 is installed inside, which divides the vertical force converted by the conflicting structure into two parts:

[0057] The first part maintains the vertical force to increase the height of the electromagnetic shielding layer 3;

[0058] The latter part converts the vertical force into a circular motion force and provides an upward force to realize the rotation of the electromagnetic shielding layer 3 on the surface of the integrated drawer 2, and can also be raised in height during the rotation.

[0059] The rotating structure includes an adjusting sleeve 19 fixedly installed in a corner of the integrated drawer 2, a connecting rod 8 is movably inserted in the adjusting sleeve 19, sliding plates 21 are rotatably installed on both sides of the middle section of the connecting rod 8, the sliding plates 21 are slidably connected in the spiral groove 22 and the vertical groove 23, and the spiral groove 22 and the vertical groove 23 are opened on the inner wall of the adjusting sleeve 19.

[0060] In another embodiment provided by the present invention, a limiting structure is arranged in the left slider 5 and the right slider 6, and is used to provide limitations on the position and angle of the integrated drawer 2 when it is inserted into the cabinet 1, and automatically release the limitation after the integrated drawer 2 is completely pulled out to achieve rotation and tilting of the integrated drawer 2.

[0061] The limiting structure includes a telescopic groove 26 opened at the top of the left slider 5 and the right slider 6, and the telescopic rod 14 and the trapezoidal plate 25 are movably inserted in the telescopic groove 26. The trapezoidal plate 25 is fixedly installed on the top of the telescopic rod 14, and the bottom end of the telescopic rod 14 is inserted in the top of the rotating groove 24 and is fixedly connected with a resistance ring 28. The bottom surface of the resistance ring 28 is slidably and resistively connected to the top of the limiting rod 27 and fits on the surface of the tilting rod 7. The bottom end of the limiting rod 27 is movably inserted in the tilting rod 7 through a limiting spring 31, and the top end of the limiting rod 27 is slidably connected to the limiting groove 30 opened on the inner side wall of the rotating groove 24, and the two ends of the top of the resistance ring 28 are connected to the two side walls of the bottom end of the telescopic groove 26 through a reset spring 29.

[0062] In another embodiment provided by the present invention, the tilting structure realizes tilting of the integrated drawer 2 at a certain angle after the tilting rods 7 arranged on both sides of the bottom end of the integrated drawer 2 lose the restriction of the limiting structure, thereby increasing the operable space inside the integrated drawer 2.

[0063] The tilting structure includes a rotation groove 24 opened on the inner bottom surface of the left slider 5 and the right slider 6. A tilting rod 7 is rotatably connected in the rotation groove 24. The top end of the tilting rod 7 is fixedly connected to both sides of the bottom end of the integrated drawer 2.

[0064] In another embodiment provided by the present invention, a transmission rod 10 is inserted into an inner wall of the integrated drawer 2 on one side of the bottom end of the integrated drawer 2 and an arc-shaped movable groove 11 is provided, so that when the integrated drawer 2 is rotated and tilted after being fully pulled out, the transmission rod 10 will slide in the movable groove 11 without restricting the rotation and tilting of the integrated drawer 2.

[0065] In another embodiment provided by the present invention, the bottom surface of the resistance ring 28 is arc-shaped. After the limit rod 27 is squeezed, the limit rod 27 is squeezed to the top end to fit the surface of the tilting rod 7. At this time, when the integrated drawer 2 is rotated downward through the spherical shape of the top end of the limit rod 27, the top end of the limit rod 27 continues to be squeezed inward and contracted and slides in the limit groove 30. When the integrated drawer 2 is tilted to the maximum tilt angle, the top end of the limit rod 27 reaches the limit position of the limit groove 30, and the transmission rod 10 also reaches the limit position of the top end of the movable groove 11.

[0066] In another embodiment provided by the present invention, preferably, a downwardly protruding resistance plate 17 arranged at the top of the opening of the insertion and withdrawal slide rail 4 will slide to the position of the resistance plate 17 when the left slider 5 and the right slider 6 slide to the position of the resistance plate 17, and the resistance plate 17 will slide against the surface of the trapezoidal plate 25 to achieve the squeezing of the limiting structure, thereby achieving the tilting rotation of the integrated drawer 2 by the tilting structure.

[0067] When in use, after installing the various integrated control unit modules of the smart grid in the integrated drawer 2 and making electrical connections, the cabinet door can be closed for use. At this time, an electromagnetic shielding layer 3 is installed on the surface of each group of integrated drawers 2 to shield the electromagnetic interference in each integrated drawer 2. At the same time, the electromagnetic shielding layer 3 is directly installed on the surface of the integrated drawer 2 to provide dust protection for each control unit module installed in the integrated drawer 2;

[0068] When it is necessary to operate the control unit module in the integrated drawer 2, the corresponding integrated drawer 2 is pulled outward, and the left slider 5 and the right slider 6 set on both sides of the bottom end of the integrated drawer 2 will slide in the insertion and withdrawal slide rail 4, so as to pull the integrated drawer 2 outward. When the integrated drawer 2 is pulled outward to a certain position, the gear 12 sliding in the inner slide rail 18 contacts the rack 13 at the bottom of the inner slide rail 18. At this time, the electromagnetic shielding layer 3 reaches a rotatable position and will not be restricted by the cabinet 1. At this time, the integrated drawer 2 continues to be pulled outward. The meshing between the gear 12 and the rack 13 drives the gear 12 to rotate. The rotation of the gear 12 drives the rotation of the resistance block 9 through the transmission rod 10. The resistance block 9 rotates in the integrated drawer 2, and the resistance ball 20 and the bottom end of the connecting rod 8 that originally resist at a lower position on the surface gradually contact the protruding position of the resistance block 9 surface as the resistance block 9 rotates. In the process of the resistance block 9 rotating and resisting, the rotational force of the gear 12 is converted into the connecting rod 8 to realize the vertical force. The connecting rod 8 divides the power into two parts while sliding up and down:

[0069] The first part maintains the vertical force to increase the height of the electromagnetic shielding layer 3;

[0070] The latter part converts the vertical force into a circular motion force and provides an upward force to realize the rotation of the electromagnetic shielding layer 3 on the surface of the integrated drawer 2, and can also be raised in height during the rotation.

[0071] When the electromagnetic shielding layer 3 is displaced upward by the vertical force of the connecting rod 8, the sliding plates 21 arranged on both sides of the connecting rod 8 slide upward in the vertical groove 23. It should be noted that due to the spiral groove 22 opened in the adjusting sleeve 19 in a spiral shape, the sliding plates 21 arranged in the middle section on both sides of the connecting rod 8 will be adapted to the height of both sides of the spiral groove 22, and the height of the electromagnetic shielding layer 3 is increased by the connecting rod 8;

[0072] When the latter part drives the electromagnetic shielding layer 3 to rotate, the sliding disks 21 on both sides of the connecting rod 8 rotate in the spiral groove 22 along with the upward squeezing force generated by the abutment block 9, and the connecting rod 8 is rotated in the adjustment sleeve 19 to drive the rotation of the electromagnetic shielding layer 3. After the electromagnetic shielding layer 3 is fully rotated and unfolded from the surface of the integrated drawer 2, when the gear 12 reaches the position near the end of the rack 13, the rack 13 limits the position of the gear 12, and at the same time, the abutment ball 20 at the bottom end of the connecting rod 8 reaches the groove 15 opened at the most protruding position of the abutment block 9 for limiting.

[0073] When the electromagnetic shielding layer 3 rotates and unfolds to the terminal rotation position about to be fully unfolded, the integrated drawer 2 reaches the limit position of being pulled out from the cabinet 1. At this time, the left slider 5 and the right slider 6 reach the top position of the insertion and withdrawal slide rail 4, and the resistance plate 17 set at the top of the opening at the top position of the insertion and withdrawal slide rail will generate a resistance and extrusion force on the trapezoidal plate 25 set at the top of the left slider 5 and the right slider 6, and squeeze the trapezoidal plate 25 into the telescopic groove 26, and shrink the trapezoidal plate 25 into the telescopic groove 26. The trapezoidal plate 25 drives the telescopic rod 14 to be inserted into the rotating groove 24, and at the same time, the surface of the tilting rod 7 is pushed out and inserted into the telescopic groove 2 through the resistance ring 28. The limiting rod 27 limited in the inner position of 6 contracts into the tilting rod 7 and squeezes the limiting spring 31, so that the top of the limiting rod 27 reaches the position at the same height as the surface of the tilting rod 7, and then the integrated drawer 2 is rotated downward. During the rotation process, the integrated drawer 2 squeezes the limiting rod 27 and rotates the limiting rod 27 in the limiting groove 30 provided in the rotation groove 24. At this time, the integrated drawer 2 will rotate through the rotation of the tilting rod 7 in the rotation groove 24, and when the integrated drawer 2 is tilted to the maximum tilting angle, the top of the limiting rod 27 reaches the limit position of the limiting groove 30, and the transmission rod 10 also reaches the limit position of the top of the movable groove 11.

[0074] The power of the integrated drawer 2 during the pulling-out process is differentiated into the force for lifting and rotating the electromagnetic shielding layer 3. At the same time, the restriction on the integrated drawer 2 is released, and the pulled-out integrated drawer 2 is tilted downward at a certain angle. While the operating space of the integrated drawer 2 is increased, the electromagnetic shielding layer 3 will also tilt at a certain angle with the integrated drawer 2 while the integrated drawer 2 rotates. The surface of the electromagnetic shielding layer 3 is set to stripes of varying depths. During the operation of the integrated drawer 2, some auxiliary tools for the operation can be placed on the surface of the electromagnetic shielding layer 3 for temporary storage, which is more practical.

[0075] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.

The integrated control cabinet for smart grid according to claim 3, characterized in that: The resistance structure is installed on one side of the bottom end of the integrated drawer (2) and is used to connect the transmission structure and to resist the rotation structure through a resistance block (9) with a conical cross section arranged inside, so as to convert the horizontal force of the integrated drawer (2) into a vertical force to raise the electromagnetic shielding layer (3) to a higher height, and then cooperate with the rotation structure to rotate the electromagnetic shielding layer (3).

5. The integrated control cabinet for smart grid according to claim 4, characterized in that: The rotating structure is installed at a corner of the integrated drawer (2) and has an adjusting sleeve (19) installed inside, which divides the vertical force converted by the resistance structure into two parts: The front part maintains the vertical force to increase the height of the electromagnetic shielding layer (3); The latter part converts the vertical force into a circular motion force and provides an upward force, thereby realizing the rotation of the electromagnetic shielding layer (3) on the surface of the integrated drawer (2), and the height can also be increased during the rotation.

6. The integrated control cabinet for smart grid according to claim 5, characterized in that: A limit structure is arranged in the left slider (5) and the right slider (6), and is used to limit the position and angle of the integrated drawer (2) when it is inserted into the cabinet (1), and automatically releases the limit after the integrated drawer (2) is completely pulled out to achieve rotation and tilting of the integrated drawer (2).

7. The integrated control cabinet for smart grid according to claim 6, characterized in that: The tilting structure realizes tilting of the integrated drawer (2) at a certain angle after the tilting rods (7) arranged on both sides of the bottom end of the integrated drawer (2) lose the restriction of the limiting structure, thereby increasing the operable space in the integrated drawer (2).

8. The integrated control cabinet for smart grid according to claim 7, characterized in that: The transmission rod (10) is inserted into the inner side wall of the integrated drawer (2) at one side of the bottom end of the integrated drawer (2) and is provided with an arc-shaped movable groove (11), so that when the integrated drawer (2) is rotated and tilted after being fully drawn out, the transmission rod (10) will slide in the movable groove (11) without restricting the rotation and tilting of the integrated drawer (2).

9. The integrated control cabinet for smart grid according to claim 8, characterized in that: The bottom surface of the abutment ring (28) is arc-shaped. After the limiting rod (27) is squeezed, the limiting rod (27) is squeezed to the top end to fit the surface of the tilting rod (7). At this time, when the integrated drawer (2) is rotated downward through the spherical shape of the top end of the limiting rod (27), the top end of the limiting rod (27) continues to be squeezed inward and shrinks and slides in the limiting groove (30). When the integrated drawer (2) is tilted to the maximum tilt angle, the top end of the limiting rod (27) reaches the limit position of the limiting groove (30), and the transmission rod (10) also reaches the limit position of the top end of the movable groove (11).

10. The integrated control cabinet for smart grid according to claim 9, characterized in that: A downwardly protruding abutment plate (17) provided at the top of the opening of the insertion and withdrawal slide rail (4) will slide to the position of the abutment plate (17) when the left slider (5) and the right slider (6) are in sliding abutment with the surface of the trapezoidal plate (25), thereby squeezing the limiting structure and realizing the tilting and rotation of the integrated drawer (2) by the tilting structure.
