Description

Technical Field

[0001] This invention relates to the field of electrical distribution box technology, and more particularly to a waterproof electrical distribution box. Background Technology

[0002] A distribution box is an electrical device specifically designed for distributing power. It integrates switching equipment, measuring instruments, protective electrical appliances, and auxiliary equipment, and houses these components in a closed or semi-closed metal cabinet, forming an important part of a low-voltage power distribution system.

[0003] Due to their wide range of applications, distribution boxes are used in a very broad range of fields. Depending on the usage environment, they can be divided into indoor distribution boxes and outdoor distribution boxes. Since outdoor distribution boxes are installed on the exterior of buildings or in open-air environments, they need to be exposed to the natural environment for a long time. Therefore, the design of outdoor distribution boxes must have characteristics such as waterproof, corrosion-proof, dustproof, UV-proof, and lightning protection to ensure stable operation under harsh weather conditions. However, when encountering sudden rain, the situation is often so sudden that outdoor distribution boxes cannot react in time to take measures to block the rain, which can lead to the situation where rainwater intrusion and soaking affect their normal use. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a power distribution box that can respond to rainy weather in a timely manner and is waterproof.

[0005] To address the aforementioned technical problems, this invention provides a flood-resistant distribution box, comprising a base, telescopic rods, a distribution box body, an assembly door, and a closing mechanism. A telescopic rod is provided around the top of the base, and the distribution box body is slidably mounted between the four telescopic rods. An assembly door is bolted to the front of the distribution box body, and ventilation holes are provided on both sides and the top of the distribution box body. A closing mechanism is provided on the distribution box body; the closing mechanism includes an electric push rod, a baffle plate, a guide rail, a contact frame, a guide plate, a cover plate, an elastic rope, and a contact rod. Electric push rods are provided on both sides of the distribution box body. Both sides are equipped with a set of guide rails spaced back and forth. A baffle is slidably installed between the guide rails on the same side. The lower ends of the two baffles are connected to the telescopic ends of the electric push rods on the same side. The two baffles are respectively in close contact with the heat dissipation holes on the same side. A contact frame is installed on the top of the two baffles. Guide plates are installed on both sides of the distribution box body. A cover plate is slidably installed between the two guide plates. The cover plate is located above the distribution box body. Two elastic ropes are installed between the cover plate and the two guide plates. A contact rod is installed at the bottom of both sides of the cover plate. The contact rod is made of rubber and passes through the guide plate and engages with the contact frame.

[0006] Preferably, the length of both shielding plates is greater than the length of the heat dissipation holes on both sides, forming a cover suitable for shielding the heat dissipation holes.

[0007] Preferably, the device further includes a water absorption mechanism, which includes a squeezing plate, a placement plate, a diversion plate, and a sponge. The bottom of the cover plate is provided with a squeezing plate, which penetrates the top of the distribution box body and the two are in a sliding fit. The upper inside of the distribution box body is provided with a placement plate, and both sides of the placement plate are provided with diversion plates. The placement plate is provided with a sponge, which is in contact with the squeezing plate.

[0008] Preferably, the water suction mechanism further includes a drain pipe and a water collection tank. Drain pipes are provided on both sides of the bottom of the extrusion plate. The lower ends of the two drain pipes pass through one side of the adjacent distribution box body. Water collection tanks are provided on both sides of the distribution box body. The water collection tanks are connected to the drain pipes on the same side.

[0009] Preferably, the two diversion plates are arranged in opposite directions, and the two diversion plates are streamlined plates with inward concavity.

[0010] Preferably, the device further includes an auxiliary mechanism, which includes a sensor, an inductor, and a float plate. Sensors are symmetrically arranged on the lower side of the front of the assembly door. Inductors are slidably arranged on both sensors. The inductors are electrically connected to the sensors. The sensors are inductively connected to the electric push rod. A float plate is arranged between the two sensors.

[0011] Preferably, it also includes a chassis and a lightning rod, with the chassis located on top of the cover plate and the lightning rod mounted on the chassis.

[0012] Preferably, it also includes a mounting bracket and a placement frame. The mounting bracket is provided inside the distribution box body, and a placement frame is provided on both sides of the mounting bracket.

[0013] The beneficial effects that this invention can achieve by overcoming the shortcomings of the prior art include:

[0014] 1. This invention, through the setting of a closing mechanism, uses a shielding plate and a cover plate to block the heat dissipation holes on the main body of the distribution box, and then uses a telescopic rod to raise the height of the main body of the distribution box, thereby promptly preventing rainwater from entering the box, thus coping with sudden rainy weather, avoiding rainwater soaking, and achieving the effect of waterproofing and protecting the distribution box.

[0015] 2. This invention uses a water-absorbing mechanism to collect incoming rainwater. Then, a squeezing plate squeezes the sponge to drain the water, and finally, the rainwater is discharged through a drain pipe. This allows rainwater that has entered the distribution box to be discharged, resulting in excellent practicality and significant protection.

[0016] 3. Through the setting of the auxiliary mechanism, the float will push the sensor to move as the water level rises, thereby assisting the sensor to sense the water and control the electric push rod to drive the operation of the closing mechanism, thus achieving the effect of timely response to emergencies.

It should be understood that the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0028] Example: A flood-resistant distribution box, such as Figures 1-4As shown, the distribution box includes a base 1, telescopic rods 2, a distribution box body 3, an assembly door 31, and a closing mechanism 4. A telescopic rod 2 is installed around the top of the base 1, and the distribution box body 3 is slidably mounted between the four telescopic rods 2. The distribution box body 3 is in a vertically movable state. The assembly door 31 is bolted to the front of the distribution box body 3. Ventilation holes 32 are provided on the left, right, and top sides of the distribution box body 3 to aid in heat dissipation. The closing mechanism 4 is installed on the distribution box body 3 to block the ventilation holes 32, thereby preventing heat loss. Rainwater entry; the closing mechanism 4 includes an electric push rod 41, a baffle plate 42, a guide rail 43, a contact frame 44, a guide plate 45, a cover plate 46, an elastic rope 47, and a contact rod 48. Electric push rods 41 are fixedly installed on both the left and right sides of the distribution box body 3. The electric push rods 41 are the main drive source. A set of guide rails 43 is spaced back and forth on both the left and right sides of the distribution box body 3. The guide rails 43 have a guiding function. A baffle plate 42 is slidably installed between the guide rails 43 on the same side. The lower ends of both baffle plates 42 are connected to the telescopic ends of the electric push rods 41 on the same side. The baffle plate 42 is... In the vertical movement state, the two shielding plates 42 are respectively tightly attached to the surface of the heat dissipation holes 32 on the same side, and the length of the two shielding plates 42 is greater than the length of the heat dissipation holes 32 on both sides, forming a cover suitable for shielding the heat dissipation holes 32, thereby achieving a waterproof effect. The top of each shielding plate 42 is provided with a contact frame 44, and the upper end of the contact frame 44 is notched to facilitate the passage of the contact rod 48. Guide plates 45 are provided on both the left and right sides of the distribution box body 3. Sliding grooves are opened in the middle and on both sides of the guide plates 45. A cover plate 46 is slidably arranged between the two guide plates 45. Above the main body 3 of the distribution box, the heat dissipation holes 32 on the top of the main body 3 of the distribution box can be blocked. Two elastic ropes 47 are respectively provided between the left and right sides of the cover plate 46 and the two guide plates 45. The elastic ropes 47 have a rebound effect to assist the cover plate 46 to move downward. Contact rods 48 are provided at the bottom of the left and right sides of the cover plate 46. The contact rods 48 are arranged longitudinally, and the lower end of the contact rods 48 is made of rubber with a raised side. The contact rods 48 pass through the guide plates 45 and are in contact with the contact frame 44. The raised side at the lower end can help the contact rods 48 pass through the contact frame 44.

[0029] like Figure 5 and Figure 6As shown, the device also includes a water absorption mechanism 5, which includes a squeezing plate 51, a placement plate 52, a diversion plate 53, and a sponge 54. The squeezing plate 51 is located at the bottom of the cover plate 46 and can move up and down. The squeezing plate 51 passes through the top of the distribution box body 3 and the two are in a sliding fit. The placement plate 52 is located on the upper side of the inside of the distribution box body 3. Diversion plates 53 are located on both the left and right sides of the placement plate 52. The two diversion plates 53 are arranged in opposite directions and are streamlined plates with inward concavity, which can guide the flow of water. The placement plate 52 is provided with a sponge 54, which can absorb the rainwater. At the same time, the sponge 54 is in contact with the squeezing plate 51 and the water in the sponge 54 can be squeezed out by the squeezing plate 51.

[0030] like Figure 5 and Figure 6 As shown, the water suction mechanism 5 also includes a drain pipe 55 and a water collection tank 56. Drain pipes 55 are provided on both the left and right sides of the bottom of the extrusion plate 51. The drain pipes 55 are used for water discharge. The lower ends of the two drain pipes 55 pass through one side of the adjacent distribution box body 3. Water collection tanks 56 are provided on both the left and right sides of the distribution box body 3. The water collection tanks 56 are connected to the drain pipes 55 on the same side. The water collection tanks 56 can collect the water flow from the drain pipes 55, so that rainwater entering from the outside can be discharged.

[0031] like Figure 5 and Figure 7 As shown, this device also includes an auxiliary mechanism 6, which includes a sensor 61, an inductor 62, and a float plate 63. Sensors 61 are symmetrically arranged on the lower left and right sides of the front of the assembly door 31. Sensors 61 can transmit signals. Inductors 62 are slidably arranged through both sensors 61. Inductors 62 can move up and down and are electrically connected to sensors 61. Sensors 61 are inductively connected to electric push rod 41. A float plate 63 is arranged between the two sensors 62. The float plate 63 can float upward by the buoyancy of the water, thereby driving the sensors 62 to move upward to detect the water level. Then, the sensors 61 collect the signal and transmit the signal to the electric push rod 41 to activate the closing mechanism 4.

[0032] like Figure 8 As shown, it also includes a chassis 7 and a lightning rod 71. The chassis 7 is fixedly installed at the top center of the cover plate 46, and the lightning rod 71 is installed on the chassis 7. The lightning rod 71 can help the distribution box body 3 avoid lightning.

[0033] like Figure 8As shown, it also includes a mounting bracket 33 and a placement frame 72. The mounting bracket 33 is provided inside the distribution box body 3. Placement frames 72 are provided on both the left and right sides of the mounting bracket 33. The placement frames 72 can be used to place desiccant to help the distribution box body 3 dehumidify and waterproof.

[0034] When using the distribution box body 3, the base 1 is placed on a horizontal surface at the installation location, meaning the distribution box body 3 is in a stable state. Then, based on local weather conditions, the staff adjusts the height between the distribution box body 3 and the telescopic rod 2 to a suitable height relative to the ground, preventing the distribution box body 3 from being submerged due to excessive water depth. In rainy weather, because the distribution box body 3 has ventilation holes 32, rainwater can easily enter through these holes, affecting its operation. Therefore, when heavy rain causes the water level to rise, the float 63 will rise with the rising water level. Simultaneously, sensor 62 slides upwards on sensor 61. When it reaches a certain height, indicating heavy rain, sensor 61 transmits a signal to electric push rod 41. Upon receiving the signal, electric push rod 41 drives the baffle 42 to move upwards along the guide rail 43. As the baffle 42 moves, it presses against contact rod 48. Due to its special rubber material, the rod deforms under pressure and directly passes through the notch on contact frame 44, inserting into it. Simultaneously, the insertion of contact rod 48 removes the cover plate 46 connected to it. Under the supporting force, the elastic rope 47 returns to its original position, simultaneously causing the cover plate 46 to slide downwards. The contact rod 48 moves downwards on the guide plate 45, while the contact frame 44 moves upwards and passes through the guide plate 45. At this point, the cover plate 46 has made direct contact with the top of the distribution box body 3 through its downward movement, blocking the heat dissipation holes 32 above it. At the same time, the shielding plate 42 blocks the heat dissipation holes 32 on both sides of the distribution box body 3, preventing rainwater from entering. Meanwhile, as the cover plate 46 moves downwards, the pressure plate 51 connected to it also moves downwards. The downward movement of the sponge 54 squeezes the wet sponge body to drain the rainwater inside, and then places it on the placement plate 52. The water is then guided into the drain pipe 55 by the diversion plate 53, allowing the rainwater to enter the water collection tank 56. This prevents the water in the sponge body 54 from overflowing into the distribution box body 3. At the same time, to ensure the normal use of the distribution box body 3, the lightning rod 71 will be used for lightning protection during thunderstorms. Meanwhile, the staff can open the assembly door 31 and place the desiccant in the placement frame 72 to dehumidify the interior, thereby better protecting the distribution box body 3.

[0035] The embodiments described above are merely preferred embodiments of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications, improvements, and substitutions without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
