Description

Technical Field

[0001] The present invention relates to the technical field of power distribution cabinets, in particular to a self-moving anti-seepage outdoor power distribution cabinet. Background Art

[0002] A distribution cabinet is a device that assembles switchgear, measuring instruments, protective electrical equipment and auxiliary equipment in a closed or semi-closed metal cabinet according to electrical wiring requirements. Its layout should meet the requirements for normal operation of the power system. It should not only be easy to maintain, but also not endanger the safety of people and surrounding equipment.

[0003] At present, since the distribution cabinet has a protective structure on the outside, it is generally installed outdoors for use. However, the current distribution cabinet is mainly fixed and inconvenient to move. Once floods occur in rainy seasons, it is very easy to be submerged.

DETAILED DESCRIPTION

[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0037] Next, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, cross-sectional views of device structures may be partially enlarged and not to scale when describing the embodiments of the present invention. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, three-dimensional dimensions, including length, width, and depth, should be included.

[0038] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0039] The present invention provides a self-moving anti-seepage outdoor power distribution cabinet, which replaces the traditional anti-seepage method of outdoor power distribution cabinets, avoiding the problem that the power distribution cabinet is easily submerged or water seeps into the interior when encountering floods or instantaneous heavy rainfall.

[0040] Figure 1-Figure 7 The figure shows a schematic diagram of the structure of a self-moving anti-seepage outdoor power distribution cabinet of the present invention. Figure 1-Figure 7 A detailed introduction is given to this self-moving anti-seepage outdoor distribution cabinet.

[0041] Example 1

[0042] refer to Figures 1-6 The present invention discloses a self-moving anti-seepage outdoor power distribution cabinet, the main body of which includes a cabinet body 100, a flood-proof self-moving base 200, an anti-seepage mechanism 300 and an adaptive sealing mechanism 400.

[0043] refer to Figure 1-Figure 4 , the cabinet 100 is used to facilitate the installation of power equipment and other components;

[0044] refer to Figure 1-Figure 4 The flood-proof self-moving base 200 is used to support the cabinet 100. The flood-proof self-moving base 200 is located at the bottom of the cabinet 100. When the water level at the bottom of the cabinet 100 rises, the flood-proof self-moving base 200 is automatically lifted and automatically starts to move during the lifting process. Therefore, when the water level at the bottom of the cabinet 100 rises, the flood-proof self-moving base 200 is automatically lifted, thereby preventing the water level from seeping into the cabinet 100 after the water level rises. At the same time, the flood-proof self-moving base 200 starts to move automatically, thereby facilitating and driving the cabinet 100 to move to a higher position, thereby preventing the cabinet 100 from being submerged.

[0045] refer to Figure 1-Figure 3The anti-seepage mechanism 300 is used to prevent water from flooding into the top of the cabinet 100 due to heavy rainfall. The anti-seepage mechanism 300 is installed on the top of the cabinet 100. The anti-seepage mechanism 300 has a first state in which it is rolled up under normal circumstances, and when the flood-proof self-moving base 200 is lifted, the anti-seepage mechanism 300 is driven to switch to a second state in which a drainage slope is formed on the top of the cabinet 100 after it is unfolded. Therefore, when the external rainfall is not large and the water level is not high, the anti-seepage mechanism 300 is in the first state. When the external heavy rainfall causes the water level at the bottom of the cabinet 100 to rise, the flood-proof self-moving base 200 is lifted, which automatically drives the anti-seepage mechanism 300 to switch to the second state, and after unfolding, a drainage slope is formed on the top of the cabinet 100, so that rainwater on the top of the cabinet 100 is quickly discharged through the drainage slope, thereby preventing rainwater from accumulating on the top of the cabinet 100.

[0046] refer to Figures 1-6 The adaptive sealing mechanism 400 is used to tighten the door gap of the cabinet 100 when there is heavy rainfall and the external water level rises, thereby preventing rainwater from seeping in through the door gap. The adaptive sealing mechanism 400 is installed at the door gap of the cabinet 100. When the anti-seepage mechanism 300 switches to the second state, it automatically drives the adaptive sealing mechanism 400 to expand, and squeezes and seals the door gap of the cabinet 100. When the anti-seepage mechanism 300 switches to the second state, the adaptive sealing mechanism 400 automatically starts working at the door gap to expand, thereby fitting more closely with the door gap and increasing the sealing effect.

[0047] In this embodiment, the specific usage process is as follows: when heavy rain occurs outside and the water level at the bottom of the cabinet 100 rises, the flood-proof self-moving base 200 is automatically lifted according to the water level, thereby preventing the cabinet 100 from being flooded. At the same time, the flood-proof self-moving base 200 begins to move, so as to facilitate driving the cabinet 100 to move to a higher position. During the lifting process of the flood-proof self-moving base 200, the anti-seepage mechanism 300 is automatically driven to switch from the first state to the second state, forming a drainage slope on the top of the cabinet 100, thereby facilitating the rapid discharge of rainwater on the top of the cabinet 100, and preventing rainwater from accumulating on the top of the cabinet 100 and causing rainwater to flow in from the top of the cabinet 100. At the same time, the adaptive sealing mechanism 400 automatically begins to expand at the door gap of the cabinet 100, thereby fitting tightly with the inner wall of the door gap, thereby encrypting the door gap of the cabinet 100 and further preventing rainwater from seeping in from the door gap.

[0048] Example 2

[0049] Based on Example 1, Figure 1-Figure 4The flood prevention self-moving base 200 includes a base 210 movably sleeved on the bottom of the cabinet 100 and having moving wheels 210a at the four corners of the bottom, a buoyancy airbag group 220 located in the groove at the bottom of the base 210, a water level sensing component 230 installed on both sides of the base 210 and transmission-connected to the buoyancy airbag group 220, and a first transmission component 240 with one end transmission-connected to the driving wheel and the other end transmission-connected to the base 210. The base 210 is used to conveniently support the cabinet 100, and the moving wheels 210a are used to When rotating, it drives the base 210 and the cabinet 100 to move. The buoyancy airbag group 220 is used to generate buoyancy after expansion, thereby driving the base 210 to rise, thereby preventing the rising water level from contacting the cabinet 100. The water level sensing component 230 is used to sense the external water level and trigger the buoyancy airbag group 220 to inflate when the water level reaches a certain height. The first transmission component 240 is used to drive the moving wheel 210a to rotate when the base 210 is lifted, thereby driving the entire base 210 and the cabinet 100 to move.

[0050] In this embodiment, reference Figure 1-Figure 4 The buoyancy airbag group 220 includes a plurality of independent air chambers located in the groove at the bottom of the base 210 and connected to each other through bellows, which are used to expand synchronously when the inflation valve 220a is opened, thereby maintaining the balance of the base 210 and the cabinet 100. When the bellows expands, it squeezes the bottom of the base 210 to form an air cushion layer, which has both shock absorption and rodent prevention functions. The input end of the buoyancy airbag group 220 is connected to the inflation valve 220a located on the side wall of the cabinet 100, which is used to inflate the buoyancy airbag group 220 when it is opened.

[0051] In this embodiment, reference Figure 1-Figure 4 The water level sensing assembly 230 includes a connecting rod 230a installed at one end on the side wall of the base 210 and a float 230b located at the other end of the connecting rod 230a and having a connecting rod at the bottom. The connecting rod 230a is a telescopic rod, and the connecting rod corresponds to the valve stem of the inflation valve 220a. The connecting rod 230a is used to facilitate the installation of the float 230b. When the water level rises and drives the float 230b to rise to the moving height, the float 230b pushes the valve stem of the inflation valve 220a to rotate through the connecting rod, thereby opening the inflation valve 220a and inflating the buoyancy airbag group 220. The connecting rod 230a is a telescopic rod used to facilitate the float 230b to float up and maintain relative displacement with the base 210.

[0052] In this embodiment, reference Figure 3The bottom of the cabinet 100 has an elastic connecting plate 110 connected to the inner wall of the groove at the top of the base 210, which is used to allow the cabinet 100 to move relative to the base 210 in a short period of time under the action of its own gravity during the lifting process of the base 210. The side wall of the cabinet 100 has a first limiting sliding groove 120 for limiting the installation of the transmission gear 240a-1;

[0053] The moving wheel 210a has a counterweight inside and an elastic member connected between the top and the bottom of the base 210. When the buoyancy airbag assembly 220 is inflated and the base 210 rises due to buoyancy, the moving wheel 210a maintains contact with the ground under the action of gravity and generates sufficient friction to facilitate its continuous movement. Two adjacent moving wheels 210a on the same side are connected by a connecting shaft.

[0054] refer to Figure 1-Figure 4 The first transmission assembly 240 includes a bevel gear set 240a with one end located on the side wall of the moving wheel 210a and the other end having a transmission gear 240a-1, a first threaded rod 240b located on the side wall of the base 210, and a first threaded cylinder 240c located on the side wall of the cabinet 100 and corresponding to the first threaded rod 240b. The bevel gear set 240a is used to drive the moving wheel 210a to rotate when it rotates, and the first threaded rod 240b is used to drive the threaded cylinder to rotate when the base 210 is lifted and driven to rise. When the cylinder is used to rotate, it drives the transmission gear 240a-1 to rotate under the action of the bevel tooth groove. The outer wall of the first threaded cylinder 240c has a bevel tooth groove that engages with the transmission gear 240a-1, which is used to drive the transmission gear 240a-1 to rotate during the upward movement. The top of the transmission gear 240a-1 has a first limiting rod 240a-11 whose other end extends into the first limiting groove 120, which is used to limit the installation of the transmission gear 240a-1, thereby maintaining the stability of its lifting and lowering movement.

[0055] In this embodiment, the specific working process is as follows: when the external water level rises, the float 230b rises under the action of buoyancy. When the float 230b floats to a certain height, the valve stem of the inflation valve 220a is driven to rotate under the driving force of the connecting rod, so that after the inflation valve 220a is opened, the buoyancy airbag group 220 begins to inflate. After the buoyancy airbag group 220 is inflated, buoyancy is formed on the base 210 of the base 210, thereby forcing the base 210 to lift upward. During this process, the first threaded rod 240b rises and drives the first threaded cylinder 240c to rotate. When the first threaded cylinder 240c rotates, it drives the transmission gear 240a-1 to rotate. When the transmission gear 240a-1 rotates, it drives the bevel gear group 240a to rotate. When the bevel gear group 240a rotates, it drives the moving wheel 210a to rotate, thereby driving the base 210 and the cabinet 100 to move automatically, thereby preventing the cabinet 100 from being flooded.

[0056] Example 3

[0057] Based on Example 2, Figure 1-Figure 3 The anti-seepage mechanism 300 includes mounting rods 310 located on both sides of the top of the cabinet 100, a movable frame 320 movably sleeved on the mounting rods 310, a rolling plate 330 located on one side of the movable frame 320, and a second transmission assembly 340 with one end transmission connected to the movable frame 320 and the other end transmission connected to the first threaded cylinder 240c. The mounting rods 310 are used to slide and install the movable frame 320, and the movable frame 320 is used to facilitate the installation of the rolling plate 330. The rolling plate 330 is used to cover the top of the cabinet 100 after being unfolded, and the second transmission assembly 340 is used to drive the movable frame 320 to rise when the first threaded cylinder 240c rotates, thereby opening the rolling plate 330.

[0058] In this embodiment, reference Figure 1-Figure 3 The cabinet body 100 has inclined frames 140 on both sides of the top for supporting the unfolded roll plate 330. At the same time, the unfolded roll plate 330 maintains a certain inclination angle with the top of the cabinet body 100, thereby facilitating the rapid drainage of rainwater from the surface of the roll plate 330. The side wall of the cabinet body 100 has a second limiting slide groove 130 for limiting the second threaded rod 340b.

[0059] refer to Figure 1-Figure 4The second transmission assembly 340 includes a second threaded cylinder 340a connected to the first threaded cylinder 240c by a rotating shaft at the bottom, a second threaded rod 340b corresponding to the second threaded cylinder 340a and having a second limiting rod 340b-1 on the side wall, and a push rod 340c located at the top of the second threaded rod 340b and corresponding to the movable frame 320. The second threaded cylinder 340a is used to rotate with the second threaded rod moving upward under the limiting action of the second limiting rod 340b-1. The second threaded rod 340b is used to drive the push rod 340c to push upward when moving upward. The push rod 340c is used to move upward and contact the bottom of the movable frame 320, pushing the movable frame 320 upward along the mounting rod 310. The second limiting rod 340b-1 extends into the second limiting slide groove 130 to limit the second threaded rod 340b, thereby preventing the second threaded cylinder 340a from driving it to rotate synchronously when it rotates.

[0060] In this embodiment, reference Figure 1-Figure 7 After the roll plate 330 is unfolded, one end extends out of the front side of the cabinet 100 and the side wall has a V-shaped water guide groove 330a. After the roll plate 330 is unfolded, the front end extends out of the front side of the cabinet 100. When the buoyancy airbag group 220 expands to lift the cabinet 100, the bottom air is compressed to form a high-speed airflow, which flows upward along the side wall of the cabinet 100. The inclined surface formed by the unfolding roll plate 330 is tangentially angled with the airflow direction, generating a Venturi effect, thereby accelerating the discharge of hot air in the cabinet. The V-shaped cross-section of the V-shaped water guide groove 330a guides the water flow to both sides of the cabinet 100, thereby preventing rainwater from contacting the door gap during the drainage process.

[0061] In this embodiment, the specific working process is as follows: when the flood prevention self-moving base 200 is lifted and the first threaded cylinder 240c rotates, it drives the second threaded cylinder 340a to rotate synchronously. When the second threaded cylinder 340a rotates, it drives the second threaded rod 340b to move upward under the limiting connection between the second limiting rod 340b-1 and the second limiting slide groove 130, so that when the second threaded rod 340b moves upward, it drives the top rod 340c to push up. When the top of the top rod 340c contacts the bottom of the movable frame 320, as the top rod 340c continues to rise, the movable frame 320 is pushed up along the mounting rod 310. At this time, the rolled-up rolling plate 330 is lifted to After reaching a certain angle, it unfolds along the inclined frame 140 under the action of its own tilting force, thereby forming a drainage slope on the top of the cabinet 100, thereby shielding the top of the cabinet 100 from rain. At the same time, the slope facilitates the rapid discharge of rainwater from the top of the roll plate 330, thereby avoiding the accumulation of rainwater. The rainwater quickly enters the V-shaped water guide groove 330a and is discharged from both sides of the cabinet 100. During this process, when the buoyancy airbag group 220 expands to lift the cabinet 100, the air at the bottom is compressed to form a high-speed airflow, which flows upward along the side wall of the cabinet 100. The slope formed by the unfolding of the roll plate 330 is tangential to the airflow direction, resulting in a Venturi effect, thereby accelerating the discharge of hot air in the cabinet.

[0062] Example 4

[0063] Based on Example 3, Figure 6 , the door frame of the cabinet 100 has a mounting groove 150 for facilitating the installation of a variable-section sealing strip 410;

[0064] refer to Figures 1-6 The adaptive sealing mechanism 400 includes a variable-section sealing strip 410 installed in the installation groove 150, which is used to seal the door gap of the cabinet 100 to prevent rainwater from seeping in through the door gap.

[0065] In this embodiment, the interior of the variable-section sealing strip 410 is a hollow structure, which is used to expand when the interior is inflated, so that the outer wall thereof fits more closely with the inner wall of the door gap, thereby enhancing the anti-water seepage effect;

[0066] refer to Figure 1-Figure 7, negative pressure connection ports 330b are provided on both sides of the bottom of the rolling plate 330, which are adjacent to the two ends of the V-shaped water guide groove 330a and connected to the interior of the cavity of the variable-section sealing strip 410 through a hose. When the two ends of the V-shaped water guide groove 330a are draining water quickly, an air flow vortex is formed in the area below the groove, thereby forming a negative pressure area in a certain area. At this time, the negative pressure connection port 330b is sucked from the outside due to the negative pressure at one end, and the sucked air is discharged into the cavity of the variable-section sealing strip 410 through the hose, thereby causing the variable-section sealing strip 410 to expand, so that its outer wall fits tightly with the inner wall of the door gap, thereby adaptively adjusting the sealing effect.

[0067] In this embodiment, the specific working process is as follows: when the rolling plate 330 is unfolded and draining, rainwater is quickly discharged from both ends of the V-shaped water guide groove 330a. At the same time, a negative pressure area is formed in the area below the groove after the air flow vortex travels to a certain area. At this time, the negative pressure connection port 330b is sucked in from the outside due to the negative pressure at one end. The sucked air is quickly introduced into the cavity of the variable-section sealing strip 410 through the hose. The internal air pressure of the variable-section sealing strip 410 increases and begins to expand, so that the outer wall of the variable-section sealing strip 410 fits tightly to the door gap, thereby realizing adaptive sealing adjustment and enhancing the anti-seepage effect of the cabinet body 100.

[0068] Although the present invention has been described above with reference to embodiments, various modifications may be made thereto and equivalent components may be substituted without departing from the scope of the present invention.
