Description

Technical Field

[0001] The invention relates to an underground distribution box, in particular to an underground distribution box, and belongs to the technical field of distribution boxes. Background Art

[0002] As a common type of underground distribution box, the distribution box is usually installed on walls, poles and other facades. However, when a short circuit or other fault in the power element of the distribution box exposed outdoors causes a fire, it is easy to cause damage to surrounding buildings or pedestrians. At the same time, its rain and dust resistance is also poor. Therefore, underground distribution boxes are gradually becoming popular. They have the advantages of not taking up space and not affecting the flow of people and vehicles. In addition, underground substations have appeared in the prior art. By setting power equipment such as transformers and distribution cabinets below the bottom surface, the land use area can be reduced. The underground substation is to completely bury the traditional box transformer and semi-underground box transformer below the ground, and the ground does not affect the use.

[0003] Chinese invention patent announcement number CN115173295B discloses "a waterproof and anti-seepage structure of an underground box-type substation, comprising: an underground shell and a lifting assembly installed inside the underground shell, a distribution box assembly is installed on the top of the lifting assembly, and clamping assemblies are installed on both sides of the inner wall of the underground shell and at positions corresponding to the distribution box assembly, and a pumping assembly is also installed on the side of the underground shell; wherein the underground shell is used to bury the substation underground; wherein the lifting assembly is used to lift the distribution box assembly; wherein the clamping assembly is used to fix the distribution box assembly during lifting. This invention can not only effectively drain the accumulated water inside the substation during the flood season, thereby avoiding damage to the internal components of the substation caused by the accumulated water, but also facilitates the substation to be lifted to the ground, thereby greatly facilitating the maintenance of the substation by the staff";

[0004] The above patent has the following defects: it uses sensors to sense information and then cooperates with the controller to discharge the accumulated water. The design relies on sensors and controllers to detect accumulated water and trigger the drainage mechanism. However, the sensor needs to work in the underground environment for a long time and may be affected by various factors such as soil moisture, temperature, and chemicals, resulting in reduced sensitivity or failure. The controller is the "brain" of the entire drainage system. Once the controller fails, it may cause the drainage system to fail to work properly, thereby causing water accumulation problems.

[0005] Therefore, it is urgent to improve the above patent to solve the above problems. Summary of the invention

This design simplifies maintenance work and reduces maintenance costs.

[0027] 4. In the underground distribution box, the second magnetic disk realizes rapid adjustment of the magnetic pole through the design of the adjustment disk and the driving structure inside the shell. When the water level changes, the adjustment disk can be driven to rotate by the motor to quickly change the alignment state of the magnetic groove, thereby adjusting the magnetic force between the second magnetic disk and the first magnetic disk and accelerating the response speed of the driving mechanism.

[0028] 5. The underground distribution box, through the design of the magnetic slot and the docking hole, allows flexible adjustment of the magnetic force of the second magnetic disk. By adjusting the rotation of the disk, the alignment of the magnetic slot can be accurately controlled, thereby adjusting the size and direction of the magnetic force between the second magnetic disk and the first magnetic disk, thereby enhancing the adaptability and controllability of the system.

DETAILED DESCRIPTION

[0041] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0042] like Figure 1 - Figure 3 As shown, the underground distribution box provided in this embodiment includes a distribution box body 2 which can be lifted and installed in the underground box 1, a monitoring device 3 is arranged in the underground box 1, and an electric lifting guide rail is installed in the underground box 1 for lifting the distribution box body 2 so as to move it out of the underground box 1 for maintenance.

[0043] like Figure 2 , Figure 3 - Fig.10As shown, a water level monitoring module is provided in the underground box 1; the water level monitoring module is composed of a buoyancy mechanism 5, a driving mechanism 6, a connecting structure 7 and a valve mechanism 8; the water level monitoring module highly integrates the buoyancy mechanism 5, the driving mechanism 6, the connecting structure 7 and the valve mechanism 8 to form an automatic response system. When the water level rises, the buoyancy mechanism 5 rises with the water level and triggers the valve mechanism 8 through the connecting piece and the driving mechanism 6, realizing automatic drainage without manual intervention. The buoyancy mechanism 5 includes a float 501 arranged in the buried box 1 and a connecting piece fixed to one side of the float 501, and the float 501 is connected to the driving mechanism 6 through the connecting piece; a connecting frame 4 is fixedly installed on the left inner wall of the buried box 1, and the connecting piece includes a fixedly connected connecting ring 503 and a connecting arm 504 and a first connecting rod 502 fixedly connected between the connecting ring 503 and the float 501, and a second connecting rod 505 is hingedly installed on the top side of the connecting arm 504 and one end of the linkage rod 604, and an axial rod hingedly matched with the connecting piece is installed on the connecting frame 4, and a supporting arm 10 supporting the float 501 is installed on the outside of the connecting frame 4, which can support the float 501 at the lowest position.

[0044] In this embodiment, the buoyancy mechanism 5 accurately senses water level changes by raising and lowering the float 501. The displacement of the float 501 is converted into mechanical action through the connector and the driving mechanism 6, thereby triggering the opening or closing of the valve mechanism 8, ensuring accurate monitoring and timely response to water level changes.

[0045] In addition, the buoyancy mechanism 5 has certain flexibility and can be adjusted and optimized according to different application scenarios and requirements. For example, the buoyancy of the float 501 can be adjusted, the opening threshold of the valve mechanism 8 can be changed, etc., to meet different water level monitoring requirements.

[0046] like Figure 2 , Figure 4 - Figure 8 As shown, the pushing mechanism 6 includes a sleeve 601 fixedly arranged inside the underground box 1, a first disk 602 and a second disk 603 slidably arranged inside the sleeve 601 and arranged oppositely, and a linkage rod 604 is installed between the second disk 603 and the connecting member; the sleeve 601 is hollow inside and its two ends are connected, the sleeve 601 is fixedly installed on the left inner wall of the underground box 1, and the first disk 602 and the second disk 603 are arranged oppositely with the same poles. The connecting structure 7 includes a first connecting rod 701 and a second connecting rod 702 that are fixedly connected, one end of the second connecting rod 702 away from the first connecting rod 701 is fixed to the outer surface of the first disk 602, and one end of the first connecting rod 701 is connected to the valve mechanism 8.

[0047] To improve the response speed, Figure 6 -and Figure 8As shown, the second magnetic disk 603 is composed of a shell 6031, an adjustment disk 6032 rotatably arranged inside the shell 6031, and a driving structure installed on the shell 6031 for driving the adjustment disk 6032. The shell 6031 is hollow inside, and a plurality of magnetic grooves 6033 are provided inside the shell 6031 and the adjustment disk 6032. The shell 6031 is also provided with docking holes 6034, wherein the number of the docking holes 6034 is half of the number of the magnetic grooves 6033, and the plurality of docking holes 6034 are spaced apart and distributed in the magnetic grooves 6033 on the shell 6031. Specifically, the driving structure includes a rotating shaft 6036 fixed on the upper surface of the adjusting disk 6032 and extending to the outside of the housing 6031, a motor 6035 fixed on the outer surface of the housing 6031, and a transmission gear 6037 fixed on the outer surface of the rotating shaft 6036 and the output shaft of the motor 6035. The adjusting disk 6032 rotates through the driving structure, so that its magnetic groove 6033 corresponds to or staggers the magnetic groove 6033 of the housing 6031. The second magnetic disk 603 is designed by the adjusting disk 6032 and the driving structure (motor 6035 and transmission gear 6037) inside the housing 6031, so as to achieve rapid adjustment of the magnetic pole. When the water level changes, the adjusting disk 6032 can be driven to rotate by the motor 6035 to quickly change the alignment state of the magnetic groove 6033, thereby adjusting the magnetic force between the second magnetic disk 603 and the first magnetic disk 602, and accelerating the response speed of the pushing mechanism 6. A guide block that slides with the adjustment disk 6032 is fixed on the inner side of the housing 6031, and stoppers 6038 that are symmetrically distributed and located on both sides of the guide block are fixed on the inner side of the adjustment disk 6032. The design of the guide block and the stopper 6038 ensures the stability and reliability of the adjustment disk 6032 during the rotation process. The guide block provides support for sliding fit, while the stopper 6038 limits the excessive movement of the adjustment disk 6032, preventing damage caused by improper operation or external factors. In addition, the stopper 6038 can also be installed with a pressure sensing device so that the staff can quickly learn the situation of the adjustment disk 6032.

[0048] In this embodiment, the design of the magnetic slot 6033 and the docking hole 6034 allows for flexible adjustment of the magnetic force of the second magnetic disk 603. By rotating the adjustment disk 6032, the alignment of the magnetic slot 6033 can be precisely controlled, thereby adjusting the magnitude and direction of the magnetic force between the second magnetic disk 603 and the first magnetic disk 602, thereby enhancing the adaptability and controllability of the system.

[0049] like Figure 2 , Figure 4 and Fig. 9As shown, the valve mechanism 8 includes a drain pipe 1 801, a drain pipe 2 802 and a sealing plug 804 movably arranged inside the drain pipe 1 801, and a pull rod 806 connected to the bottom end of the first connecting rod 701 is welded on one side of the sealing plug 804; the drain pipe 2 802 is vertically arranged with the drain pipe 1 801, and the vertical arrangement of the drain pipe 1 801 and the drain pipe 2 802 and the flexible movement of the sealing plug 804 ensure that when the water level rises, the valve mechanism 8 can be quickly opened to allow the accumulated water to be discharged smoothly. A buffer ring 803 that closely matches the sealing plug 804 is fixedly installed at the water inlet end of the drain pipe 1 801, and a protective pad is installed on the side of the buffer ring 803 close to the sealing plug 804, which can buffer the sealing plug 804 and improve the protection effect. A fixing frame 805 is fixed inside the drainage pipe 801, and the fixing frame 805 is cross-shaped. The end of the pull rod 806 away from the sealing plug 804 passes through the fixing frame 805, and a reset spring 807 is fixed between the fixing frame 805 and the sealing plug 804. The close fit between the buffer ring 803 and the sealing plug 804, as well as the supporting effect of the reset spring 807, ensure that the valve mechanism 8 has good sealing performance under normal conditions, preventing external moisture or impurities from entering the buried box 1.

[0050] It should be noted that when the sealing plug 804 is not activated, the sealing plug 804 is tightly fitted with the buffer ring 803, and the sealing plug 804 is located in front of the second drain pipe 802, thereby sealing the second drain pipe 802. When the sealing plug 804 is pulled, the sealing plug 804 is located behind the second drain pipe 802, and the accumulated water in the buried box 1 can be quickly discharged. The bottom end of the second drain pipe 802 extends outside the buried box 1.

[0051] To protect the monitoring device 3, Figure 2 and Fig.10As shown, a reeling mechanism 9 for adjusting the monitoring device 3 is provided inside the underground box 1, and the top of the first connecting rod 701 is connected to the reeling mechanism 9. The reeling mechanism 9 includes two limit shafts 901 fixedly installed inside the underground box 1, a reeling reel 902 and a guide wheel 903 installed on the outer surface of the two limit shafts 901, and a hanging rope 906 wound and installed on the outer surface of the reeling reel 902 and the guide wheel 903, and the end of the hanging rope 906 away from the reeling reel 902 is fixed to the upper surface of the monitoring device 3. Specifically, the reeling mechanism 9 also includes a meshing linkage gear 904 and a rack 905, and the rack 905 is fixed to the top of the second connecting rod 702. A guide structure 907 is installed between the monitoring device 3 and the underground box 1. The design of the guide structure 907 enables the monitoring device 3 to remain stable during the lifting process, avoiding damage caused by shaking or tilting. The linkage gear 904 is fixed to the end of the limit shaft 901 connected to the reel 902. When the water level rises, through the meshing of the rack 905 and the linkage gear 904, the reel 902 can rotate and reel up the suspension rope 906, thereby raising the monitoring device 3 to prevent it from being wetted or damaged by water, and the reel mechanism 9 and the valve mechanism 8 are linked through the connecting structure 7, so that the entire system can automatically respond to water level changes without human intervention.

[0052] like Figure 1 - Fig.10 As shown, the principle of the underground distribution box provided in this embodiment is as follows:

[0053] When the present invention is used, the water accumulation inside the underground box 1 is monitored through the buoyancy mechanism 5 and the monitoring device 3. When a large amount of water accumulates inside the underground box 1, the float 501 will rise and drive the first connecting rod 502 to tilt. After the first connecting rod 502 tilts, the second connecting rod 505 drives the second magnetic disk 603 to approach the first magnetic disk 602. Since the first magnetic disk 602 and the second magnetic disk 603 have the same magnetic poles, when the second magnetic disk 603 moves, it will push the first magnetic disk 602, and the valve mechanism 8 and the winding mechanism 9 are respectively started through the connecting structure 7. At this time, the valve mechanism The sealing plug 804 in the structure 8 moves outward and no longer blocks the drain pipe 1 801, so that the accumulated water in the buried box 1 is discharged from the buried box 1 along the drain pipe 1 801 and the drain pipe 2 802. At the same time, the meshing of the rack 905 and the linkage gear 904 drives the winding disk 902 to rotate, and the winding disk 902 rotates to reel in the suspension rope 906, thereby raising the monitoring device 3 to prevent the monitoring device 3 from getting wet when the water level rises rapidly, thereby protecting the monitoring device 3. After the accumulated water is discharged, the float 501 moves downward, thereby restoring the monitoring device 3 and the valve mechanism 8.
