Description

Technical Field

[0001] This invention relates to the field of power facility technology, and in particular to a power grid structure with a disconnection recovery function. Background Technology

[0002] A power grid is the entire system comprised of substations and transmission and distribution lines of various voltages within a power system. It consists of three units: substation, transmission, and distribution. The task of the power grid is to transmit and distribute electrical energy and change voltage. After the power grid structure is erected, specialized wires are needed to connect the transformers to external wiring harnesses.

[0003] However, the existing power grid structure has the following problems: When the power grid structure is used, it is necessary to use wire harnesses to connect the transformers and external controllers and other components. However, after the wire harnesses are connected, they are prone to fatigue and breakage due to long-term use. When the wire harnesses break, they can easily lap on the grid structure, causing a safety hazard of leakage. Summary of the Invention

[0004] The purpose of this invention is to provide a power grid structure with a broken wire recovery function, which can perform winding and recovery operations on broken wires, thereby reducing safety hazards.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A power grid structure with a disconnection recovery function is provided, comprising:

[0007] A mounting bracket and a transformer, wherein the transformer is mounted on the mounting bracket;

[0008] Multiple clamping mechanisms are spaced apart on the top of the transformer along the X direction. Each clamping mechanism includes a first drive assembly and a clamping part installed on the top of the transformer. The clamping part is electrically connected to the transformer. The first drive assembly is connected to the clamping part. The first drive assembly can drive the clamping part to open or close.

[0009] Multiple winding mechanisms, each corresponding to one of the clamping mechanisms, are located above the transformer and spaced apart along the X direction. Each winding mechanism includes a second drive assembly and a roller mounted on the mounting frame. The second drive assembly is connected to the roller, and the roller extends axially along the X direction.

[0010] Multiple conductive rods and multiple wires are provided. The conductive rods are mounted on the mounting frame and located above the winding mechanism. The wires are wound on the drum, with one end of the wire connected to the conductive rod and the other end selectively connected to the clamping part.

[0011] When the wire breaks, the first drive assembly drives the clamping part to open to disconnect the wire from the clamping part, and the second drive assembly drives the roller to wind the wire.

[0012] As a further embodiment of the power grid structure with disconnection recovery function, the mounting frame includes a first base plate, a second base plate, and a third base plate spaced apart from bottom to top, and two columns passing through the first base plate, the second base plate, and the third base plate. The two columns are spaced apart along the X direction. The transformer is mounted on the first base plate, and the second drive assembly and the roller are mounted on the second base plate. The power grid structure also includes multiple first springs and multiple proximity switches. The conductive rod includes a conductive rod body and a first limiting plate and a second limiting plate surrounding the conductive rod body. The conductive rod body passes through the third base plate. Each conductive rod body has a first spring sleeved around its outer periphery. The first limiting plate is located above the third base plate. The proximity switch is mounted on the side of the first limiting plate facing the third base plate. The second limiting plate is located below the third base plate. The two ends of the first spring are connected to the third base plate and the second limiting plate, respectively. The lower end of the conductive rod body is connected to the conductor.

[0013] As a further embodiment of the power grid structure with disconnection recovery function, a third drive component is also included. The third drive component is mounted on the column and connected to the second base plate. The third base plate is slidably engaged with the two columns. The third drive component can drive the second base plate to move up and down along the columns.

[0014] As a further embodiment of the power grid structure with wire breakage recovery function, the column is provided with first sliding grooves on both sides along the Y direction, the length of the first sliding grooves extends in the vertical direction, the second base plate is provided with through holes that cooperate with the column, the hole wall of the through hole is provided with a first slider facing the first sliding groove, and the third drive assembly includes a plurality of first electric push rods, each of the first sliding grooves has a first electric push rod installed on its bottom wall, and the first electric push rod is connected to the first slider.

[0015] As a further embodiment of the power grid structure with disconnection recovery function, the clamping part includes two grippers. The first driving component includes two sets of second electric push rods mounted on the top of the transformer. Each set of second electric push rods is connected to one of the grippers. The two second electric push rods can drive the grippers to open or close. When the two grippers are closed, they form a closed-loop structure. The conductor is connected to the closed-loop structure. When the two grippers are open, the conductor is separated from the grippers.

[0016] As a further embodiment of the power grid structure with disconnection recovery function, the top of the transformer is provided with a plurality of first mounting slots that correspond one-to-one with the clamping mechanism along the X direction. The length of the first mounting slot extends along the Y direction perpendicular to the X direction. A set of second electric push rods is respectively installed on the two slot walls opposite each other along the Y direction of the first mounting slot, and the two clamps are located between the two sets of second electric push rods.

[0017] As a further embodiment of the power grid structure with disconnection recovery function, the clamping part further includes a sliding seat. Each of the clamping claws is equipped with a sliding seat at its bottom. The sliding seat is connected to the second electric push rod. At least one groove wall of the first mounting groove along the X direction is provided with a second sliding groove. The sliding seat is provided with a second slider on its side wall along the X direction. The second sliding groove and the second slider are slidably engaged.

[0018] As a further embodiment of the power grid structure with disconnection recovery function, it also includes several isolation mechanisms and transmission components. Along the X direction, two isolation mechanisms are provided between every two adjacent clamping mechanisms. Each isolation mechanism includes two partition parts spaced apart along the X direction. Each partition part is connected to the corresponding sliding seat through a set of transmission components. When the clamping part opens, the clamping part drives the transmission components to close the partition part; when the clamping part closes, the clamping part drives the transmission components to open the partition part.

[0019] As a further embodiment of the power grid structure with disconnection recovery function, the top of the transformer is provided with several second mounting slots. The second sliding groove between two adjacent clamping parts is connected through the X direction to form a connecting cavity. A second mounting slot is provided between each two adjacent first mounting slots. The connecting cavity is located between the first mounting slot and the second mounting slot, and the first mounting slot is connected to the second mounting slot through the connecting cavity. The transmission component includes a first rack, a gear and a second rack. The gear is installed at the bottom of the second mounting slot. The second slider passes through the connecting cavity and is connected to the first rack. The second rack is fixed on the side of the partition facing the corresponding clamping part. The gear meshes with the first rack and the second rack on both sides of its circumference.

[0020] As a further embodiment of the power grid structure with disconnection recovery function, the partition includes a partition plate and a guide assembly. The guide assembly is installed in the second mounting groove, the second rack is fixedly connected to the partition, and the guide assembly is connected to the partition plate to guide the movement of the partition plate in the Y direction.

[0021] Beneficial effects:

[0022] This invention winds a conductor onto a roller, connecting both ends of the conductor to a clamping part connected to a transformer and a conductive rod, respectively. During normal use, a second drive assembly drives the roller to wind the conductor, maintaining its tension. When the conductor breaks, a first drive assembly opens the clamping part to release the conductor, disconnecting it from the clamping part. The second drive assembly then drives the roller to wind the conductor, recovering the broken wire. This prevents the broken conductor from lapping on the grid and causing a potential electrical leakage hazard.

[0023] The present invention installs a first spring and a proximity switch on a conductive rod. When the wire breaks, the first spring drives the conductive rod to move upward, thereby causing the proximity switch to move upward and separate from the third substrate. This triggers the first driving assembly to open the clamping part and the second driving assembly to drive the roller to wind the broken wire.

[0024] This invention features a partition mechanism on the side of each clamping mechanism closest to the other. The two partitions of each partition mechanism are connected to the sliding seats of the corresponding clamping parts of the clamping mechanism via a transmission assembly. The opening and closing of the clamping parts drives the transmission assembly to close or open the two partitions. When a conductor breaks, the two jaws of the clamping part open, simultaneously driving the two partitions to close. The roller then winds up the broken conductor. The closed partitions improve the safety of maintenance personnel and reduce the risk of electric shock. When the conductor is intact, the two jaws close, separating the two partitions. This provides good ventilation between adjacent clamping parts, preventing heat dissipation from being affected by the partitions on the clamping parts and the top of the transformer.

[0050] Example 1

[0051] like Figures 1 to 7 As shown, the power grid frame with wire breakage recovery function in this embodiment includes a mounting frame 100, a transformer 200, multiple clamping mechanisms 300, multiple winding mechanisms 400, multiple conductive rods 500, and multiple conductors 610.

[0052] Transformer 200 is mounted on mounting bracket 100;

[0053] Multiple clamping mechanisms 300 are spaced apart on the top of the transformer 200 along the X direction. Each clamping mechanism 300 includes a first drive assembly 310 and a clamping part 320 mounted on the top of the transformer 200. The clamping part 320 is electrically connected to the transformer 200. The first drive assembly 310 is connected to the clamping part 320. The first drive assembly 310 can drive the clamping part 320 to open or close.

[0054] The winding mechanism 400 corresponds one-to-one with the clamping mechanism 300. Multiple winding mechanisms 400 are located above the transformer 200 and are spaced apart along the X direction. Each winding mechanism 400 includes a second drive assembly 410 and a roller 420 mounted on the mounting frame 100. The second drive assembly 410 is connected to the roller 420, and the roller 420 extends axially along the X direction.

[0055] The conductive rod 500 is mounted on the mounting frame 100 and located above the winding mechanism 400. The wire 610 is wound on the roller 420, and one end of the wire 610 is connected to the conductive rod 500, while the other end is selectively connected to the clamping part 320.

[0056] When the wire 610 breaks, the first drive assembly 310 drives the clamping part 320 to open to disconnect the wire 610 from the clamping part 320, and the second drive assembly 410 drives the roller 420 to wind the wire 610.

[0057] In this embodiment, the transformer 200 is mounted on the mounting bracket 100 and connected to the conductive rod 500 via a wire 610, which in turn connects the external wiring harness. Without the winding mechanism 400, if the wire 610 experiences fatigue fracture after prolonged use, the broken wire 610 could easily lap onto the wire mesh, creating a potential safety hazard of electrical leakage. In the winding mechanism 400 of this embodiment, after the wire 610 is wound onto the roller 420, both ends of the wire 610 are connected to the clamping part 320 connected to the transformer 200 and the conductive rod 500, respectively. When the conductor 610 is in normal use, the second drive assembly 410 drives the roller 420 to wind the conductor 610, keeping the conductor 610 taut. When the conductor 610 breaks, the first drive assembly 310 drives the clamping part 320 to open to disconnect the conductor 610 from the clamping part 320. The second drive assembly 410 then drives the roller 420 to wind the conductor 610, thus recovering the broken conductor and preventing the safety hazard of leakage caused by the broken conductor 610 sprawling on the grid.

[0058] Furthermore, the mounting frame 100 includes a first substrate 110, a second substrate 120, and a third substrate 130 spaced apart from bottom to top, and two pillars 140 passing through the first substrate 110, the second substrate 120, and the third substrate 130. The two pillars 140 are spaced apart along the X direction. The transformer 200 is mounted on the first substrate 110, and the second drive assembly 410 and the roller 420 are mounted on the second substrate 120. Figure 3 As shown, the power grid structure also includes multiple first springs 710 and multiple proximity switches 720. The conductive rod 500 includes a conductive rod body 510 and a first limiting plate 520 and a second limiting plate 530 arranged around the outer periphery of the conductive rod body 510. The conductive rod body 510 passes through the third substrate 130. A first spring 710 is sleeved on the outer periphery of each conductive rod body 510. The first limiting plate 520 is located above the third substrate 130. The proximity switch 720 is installed on the side of the first limiting plate 520 facing the third substrate 130. The second limiting plate 530 is located below the third substrate 130. The two ends of the first spring 710 are respectively connected to the third substrate 130 and the second limiting plate 530. The lower end of the conductive rod body 510 is connected to the wire 610.

[0059] The first spring 710 ensures that the proximity switch 720 at the bottom of the first limiting plate 520 always tends to move away from the third substrate 130. The second drive assembly 410 drives the roller 420 to wind the wire 610. By tensioning the wire 610, the first limiting plate 520 and the conductive rod body 510 overcome the force of the first spring 710 and move towards the third substrate 130, causing the proximity switch 720 mounted at the bottom of the first limiting plate 520 to come into contact with the third substrate 130. When the wire 610 breaks, the first spring 710 drives the conductive rod 500 to move upward, thereby causing the proximity switch 720 to move upward, separating it from the third substrate 130. This triggers the first drive assembly 310 to drive the clamping part 320 to open and the second drive assembly 410 to drive the roller 420 to wind the broken wire 610.

[0060] The mounting bracket 100 in this embodiment also includes a base 150, which is fixed to the bottom of the two columns 140 and can be fixed to the ground by bolts.

[0061] Furthermore, such as Figure 1 As shown, it also includes a third drive component 800, which is mounted on the column 140 and connected to the second substrate 120. The third substrate 130 is slidably engaged with the two columns 140, and the third drive component 800 can drive the second substrate 120 to move up and down along the column 140.

[0062] In this embodiment, the second base plate 120 and the second drive assembly 410 and roller 420 mounted on the second base plate 120 are driven to move up and down by the third drive assembly 800. When the second drive assembly 410 drives the roller 420 to wind the wire 610, and the two ends of the wire 610 are respectively connected to the conductive rod body 510 and the clamping part 320, the third drive assembly 800 can assist the second drive assembly 410 in pulling down the conductive rod 500, so that the proximity switch 720 at the bottom of the first limiting plate 520 abuts against the third base plate 130.

[0063] Furthermore, the column 140 has first sliding grooves 141 on both sides along the Y direction, and the length of the first sliding grooves 141 extends vertically. The second base plate 120 has through holes 121 that mate with the column 140. The wall of the through hole 121 is provided with a first slider 122 facing the first sliding groove 141. Figure 5 The third drive assembly 800 includes a plurality of first electric push rods 810, with one first electric push rod 810 mounted on the bottom wall of each first slide groove 141, and the first electric push rod 810 being connected to the first slider 122.

[0064] In this embodiment, a first slide groove 141 is opened on the outside of the column 140, and a first electric push rod 810 is installed on the bottom wall of the first slide groove 141. The first electric push rod 810 drives the first slider 122 to move the entire second substrate 120 and the winding mechanism 400 up and down, so as to realize the contact between the proximity switch 720 and the third substrate 130.

[0065] The first slider 122 has a cross-shaped structure and serves as a limit. The mechanism of the first groove 141 matches the shape of the first slider 122. One end of the first groove 141 in the vertical direction can be designed as an open structure to facilitate the assembly of the second base plate 120 and the column 140.

[0066] For example, the second substrate 120 is provided with mounting holes 123 spaced apart along the X direction. The mounting holes 123 penetrate the second substrate 120 vertically. Multiple rollers 420 are connected by a fixed shaft 430. The length of the fixed shaft 430 extends along the X direction. Both ends of the fixed shaft 430 are rotatably connected to the hole walls of the mounting holes 123. There is at least one set of second drive components 410. Each set of second drive components 410 includes a motor 411, a first helical gear 412 and a second helical gear 413. The motor 411 is mounted on the outer wall of the mounting hole 123 along the Y direction on the second substrate 120 and is connected to the first helical gear 412 through an output shaft. The length of the output shaft extends along the Y direction. The second helical gear 413 is fixed on the fixed shaft 430. The first helical gear 412 meshes with the second helical gear 413. The motor 411 can drive the first helical gear 412 to drive the second helical gear 413 to rotate. The second helical gear 413 drives the fixed shaft 430 to drive the rollers 420 to rotate, thereby realizing the winding operation of the wire 610.

[0067] In this embodiment, a second drive assembly 410 is provided between every two adjacent rollers 420 to improve the winding efficiency of the wire 610.

[0068] Furthermore, two baffles 124 are provided between every two adjacent rollers 420. The two ends of the two baffles 124 along the Y direction are respectively fixedly connected to the wall of the mounting hole 123. The two baffles 124 are spaced apart along the X direction, and the first helical gear 412 and the second helical gear 413 are located between the two baffles 124. Figure 4 As shown, there are three rollers 420 and two sets of second drive components 410. By setting baffles 124 between two adjacent rollers 420, the installation stability of the fixed shaft 430 and rollers 420 can be improved, and the first helical gear 412 and the second helical gear 413 can also be protected.

[0069] Furthermore, the clamping part 320 includes two grippers 321, and the first drive assembly 310 includes two sets of second electric push rods 311 mounted on the top of the transformer 200. Each set of second electric push rods 311 is connected to one of the grippers 321. The two second electric push rods 311 can drive the grippers 321 to open or close. When the two grippers 321 are closed, they form a closed loop structure. The wire 610 is connected to the closed loop structure. When the two grippers 321 are open, the wire 610 is separated from the grippers 321.

[0070] Understandably, designing the closed gripper 321 as a closed-loop structure facilitates the connection between the wire 610 and the clamping part 320. When the wire 610 breaks, the first drive assembly 310 will drive the two grippers 321 to open, causing the wire 610 to automatically detach from the clamping part 320.

[0071] To further improve the connection stability between the wire 610 and the clamping part 320 in the closed state, and the smoothness of the disengagement between the wire 610 and the clamping part 320 in the open state, this embodiment also adds a first connecting ring 620 and a second connecting ring 630. The wire 610 is wound on the roller 420, with one end connected to the first connecting ring 620 and the other end connected to the second connecting ring 630. The two jaws 321 of the clamping part 320 pass through the first connecting ring 620 and close, thereby achieving the connection between the first connecting ring 620 and the clamping part 320. When the two jaws 321 of the clamping part 320 open, the first connecting ring 620 immediately disengages from the gap between the two jaws 321. A connecting hole is provided at the end of the conductive rod 500 near the transformer 200, and the second connecting ring 630 is connected to this connecting hole.

[0072] The winding mechanism 400 of this embodiment is particularly suitable for winding up a broken conductor 610 located above the roller 420.

[0073] Furthermore, such as Figure 6 and Figure 7 The top of the transformer 200 is provided with several first mounting slots 210 that correspond one-to-one with the clamping mechanism 300 along the X direction. The length of the first mounting slot 210 extends along the Y direction perpendicular to the X direction. A set of second electric push rods 311 are respectively installed on the two opposite slot walls of the first mounting slot 210 along the Y direction. Two grippers 321 are located between the two sets of second electric push rods 311.

[0074] In this embodiment, several first mounting slots 210, each corresponding to a clamping mechanism 300, are opened on the top of the transformer 200. The grippers 321 corresponding to each set of clamping mechanisms 300 are installed in the first mounting slots 210. Two second electric push rods 311 are respectively installed on two opposite walls of the first mounting slots 210. The second electric push rods 311 can drive the two grippers 321 to move in directions closer or further apart. When the first connecting ring 620 is placed between the two grippers 321, and the two second electric push rods 311 drive the corresponding grippers 321 to move in directions closer together until they are fully closed, the first connecting ring 620 is engaged in the closed-loop structure formed by the two grippers 321. When the wire 610 breaks, the second electric push rods 311 drive the two grippers 321 to open, the first connecting ring 620 disengages from the two grippers 321, and the second drive assembly 410 drives the roller 420 to wind the wire 610. In this embodiment, a first mounting groove 210 is provided on the top of the transformer 200 to facilitate the installation of the clamping mechanism 300.

[0075] For example, the two grippers 321 are semi-circular ring structures, which form a circular ring structure when closed.

[0076] The gripper 321 is electrically connected to the internal circuit structure of the transformer 200. This circuit connection is a conventional technique in the field and will not be described in detail here.

[0077] In order to further improve the stability of the movement of the gripper 321 along the Y direction by the second electric push rod 311 and to prevent the gripper 321 from deviating and getting stuck in the first mounting groove 210, this embodiment adds a guide structure for the movement of the gripper 321 along the Y direction. The guide structure includes a first guide part and a second guide part that slide and cooperate with each other.

[0078] Furthermore, the clamping part 320 also includes a sliding seat 322. Each gripper 321 has a sliding seat 322 installed at its bottom. The sliding seat 322 is connected to the second electric push rod 311. The first mounting groove 210 has a second sliding groove 220 on at least one groove wall along the X direction. The sliding seat 322 has a second slider 323 on its side wall along the X direction. The second sliding groove 220 and the second slider 323 slide in cooperation.

[0079] When the second electric push rod 311 pushes the gripper 321 to move, the second slide groove 220 and the second slider 323 slide in the Y direction, which plays a good guiding role in the movement of the gripper 321 in the Y direction.

[0080] For example, the first mounting groove 210 has two opposite groove walls along the X direction respectively provided with second sliding grooves 220. The length of the second sliding groove 220 extends along the X direction. The opening of the second sliding groove 220 is directly opposite the sliding seat 322. Correspondingly, the sliding seat 322 is provided with a second slider 323 on the side facing the second sliding groove 220. The second slider 323 slides with the second sliding groove 220. At the same time, the second slider 323 inserted into the second sliding groove 220 can also restrict the movement of the gripper 321 in the vertical direction, thereby improving the movement stability of the gripper 321 in the Y direction.

[0081] Example 2

[0082] This embodiment is basically the same as the first embodiment above, except that several partition mechanisms 900 are added.

[0083] like Figures 8 to 10 As shown, along the X direction, two partition mechanisms 900 are provided between every two adjacent clamping mechanisms 300. Each partition mechanism 900 includes two partition parts 910 spaced apart along the X direction. Each partition part 910 is connected to the corresponding sliding seat 322 via a set of transmission components 920. When the clamping part 320 opens, the clamping part 320 drives the partition part 910 to close via the transmission components 920. When the clamping part 320 closes, the clamping part 320 drives the transmission components 920 to drive the partition part 910 to separate.

[0084] In this embodiment, a partition mechanism 900 is provided on the side of each clamping mechanism 300 near the other clamping mechanism 300. The two partition portions 910 of each partition mechanism 900 are connected to the sliding seats 322 of the corresponding clamping portions 320 of the clamping mechanism 300 via a transmission assembly 920. The opening or closing of the clamping portions 320 drives the transmission assembly 920 to close or open the two partition portions 910. When the wire 610 breaks, the two grippers 321 open simultaneously, driving the two partition portions 910 to close. The roller 420 then winds up the broken wire 610. The closed partition portions 910 improve the operational safety of maintenance personnel and reduce safety hazards such as electric shock. When the conductor 610 is normal, the two clamps 321 are closed. At this time, the two partitions 910 are in a separated state, and there is good ventilation between the adjacent clamping parts 320. This can prevent the heat dissipation of the clamping parts 320 and the top of the transformer 200 from being affected by the partitions 910.

[0085] For example, the number of clamping mechanisms 300 is three sets. Since each set of clamping mechanisms 300 has a partition mechanism 900 on the side closest to another set of clamping mechanisms 300, there are two sets of partition mechanisms 900 between every two adjacent sets of clamping mechanisms 300. For the clamping mechanism 300 located in the middle, as... Figure 9The clamping mechanism 300 can simultaneously drive the two sets of partition mechanisms 900 on both sides to move; for the other two sets of clamping mechanisms 300, such as Figure 10 Each of the three sets of wires 610 connected to the three sets of clamping mechanisms 300 can drive the movement of a set of partition mechanisms 900 located on its side. If any set of wires 610 breaks, the first drive component 310 of the corresponding clamping mechanism 300 can be triggered by the proximity switch 720 to separate the third substrate 130, thereby driving the clamping part 320 to open and release the corresponding wire 610. At the same time, the clamping part 320 drives the corresponding two sets of partition parts 910 to close, thereby blocking the clamping part 320 and the adjacent clamping parts 320.

[0086] Furthermore, the top of the transformer 200 is provided with a plurality of second mounting slots 230, and a second mounting slot 230 is provided between every two adjacent first mounting slots 210. The second sliding groove 220 between two adjacent clamping parts 320 extends along the X direction to the second mounting slot 230 to form a connecting cavity. The connecting cavity is located between the first mounting slot 210 and the second mounting slot 230, and the first mounting slot 210 is connected to the second mounting slot 230 through the connecting cavity. The transmission assembly 920 includes a first rack 921, a gear 922 and a second rack 923. The gear 922 is installed at the bottom of the second mounting slot 230. The second slider 323 passes through the connecting cavity and is connected to the first rack 921. The second rack 923 is fixed on the side of the partition 910 facing the corresponding clamping part 320. The gear 922 meshes with the first rack 921 and the second rack 923 on both sides of its circumference.

[0087] The second slider 323 can move along the length direction (Y direction) of the communicating cavity. The second slider 323 serves as an intermediate connector between the sliding seat 322 and the first rack 921. When the two sliding seats 322 move towards each other along the Y direction, they drive the two second sliders 323 to move the two first racks 921 towards each other. At this time, the first racks 921 drive the gear 922 to rotate, and drive the second racks 923 to move away from each other along the Y direction, causing the two partitions 910 to separate. When the two sliding seats 322 move away from each other along the Y direction, they drive the two second sliders 323 to move the two first racks 921 away from each other. At this time, the first racks 921 drive the gear 922 to rotate in the opposite direction, and drive the second racks 923 to move towards each other along the Y direction, causing the two partitions 910 to close.

[0088] Furthermore, the partition 910 includes a partition 911 and a guide assembly 912. The guide assembly 912 is installed in the second mounting groove 230. The second rack 923 is fixedly connected to the partition 911. The guide assembly 912 is connected to the partition 911 and is used to guide the movement of the partition 911 in the Y direction to prevent the two partitions 911 from shifting during movement. Especially during the closing process, if shifting occurs, it will affect the blocking effect between the two clamping parts 320 and pose a safety hazard.

[0089] The installation position of the guide component 912 in this embodiment is not limited. It can be installed on one side of the partition 911 along the Y direction or at the bottom of the partition 911.

[0090] Exemplarily, the guide assembly 912 includes a mounting base 9121, a first guide rod 9122, and a first guide cylinder 9123. The mounting base 9121 is fixed to the side of the partition 911 facing the second mounting groove 230. The first guide cylinder 9123 is fixed to the groove wall of the second mounting groove 230 along the Y direction. One end of the first guide rod 9122 is fixedly connected to the mounting base 9121, and the other end is inserted into the first guide cylinder 9123. Of course, in other embodiments, the first guide cylinder 9123 can also be mounted on the mounting base 9121, the first guide rod 9122 can be fixed to the groove wall of the second mounting groove 230, and the first guide rod 9122 can be inserted into the first guide cylinder 9123 for sliding engagement, which can also achieve guidance of the partition 911 along the Y direction.

[0091] Furthermore, the guide assembly 912 also includes a second spring 9124, which is sleeved on the outer periphery of the first guide cylinder 9123. One end of the second spring 9124 is connected to the mounting base 9121, and the other end is connected to the groove wall of the second mounting groove 230. By sleeved the second spring 9124 on the outer periphery of the first guide cylinder 9123, damage caused by hard contact between the two partitions 911 when they are closed can be avoided.

[0092] In other embodiments, the guide assembly 912 is mounted on the bottom of the partition 911 (not shown in the figure), including a guide rail and a guide groove formed on the guide rail. The length of the guide groove extends along the Y direction. The partition 911 is inserted into the guide groove and can slide along the length direction of the guide groove.
