Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, and more specifically to a moisture-proof busbar trunking with a drainage structure. Background Technology

[0002] Busbar trunking is a new type of conductor formed by using copper or aluminum as conductors, supporting it with non-alkaline insulating materials, and installing it in a metal trough. It mainly consists of conductors, insulating materials, metal troughs, and related accessories.

[0003] Chinese Patent Publication No. CN118693739B discloses a waterproof sealed busbar trunking, comprising a busbar trunking body, with connecting covers fitted at both ends of the busbar trunking body. A protective cylinder is fixedly connected to the end of each connecting cover, and ventilation openings are provided on both sides of each protective cylinder. A sealing composite plate is fixedly installed on the inner wall of one side of each ventilation opening. This invention proposes a waterproof sealed busbar trunking. Through the configuration of the busbar trunking body, connecting covers, protective cylinders, sealing composite plates, and connecting cylinders, after two busbar trunking sections are connected, the connection point can be covered for protection. In normal weather, cold air from the outside can easily enter through the two ventilation openings on the protective cylinder, while hot air inside the protective cylinder is discharged and heat dissipated. When the humidity in the environment increases, the ventilation openings can be sealed to reduce the entry of external moisture, thereby protecting the busbar trunking joint and reducing the risk of damage and short circuits due to moisture.

[0004] However, the following shortcomings still exist: the ventilation openings need to be blocked manually to reduce the entry of external moisture and prevent water droplets from condensing at the connection points, which could cause short circuits and burn out the circuits; maintenance personnel need to pay close attention to climate changes, which is time-consuming and labor-intensive, increasing labor costs; and the process of absorbing moisture with water-absorbing and expanding resin requires regular replacement of the expanding resin, which is cumbersome. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a moisture-proof busbar trunking with a drainage structure to solve the problems existing in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a moisture-proof busbar trough with a drainage structure, comprising a conductor assembly, a housing assembly fixedly connected to the top of the conductor assembly, a drainage assembly fixedly connected to the inner side of the bottom of the housing assembly, and an air dissipation assembly fixedly connected to the top of the housing assembly. The conductor assembly includes a conductor sheet, with condensation grooves provided on both the front and back sides of the conductor sheet, and connection holes provided at both ends of the conductor sheet. The drainage assembly includes a drainage block, with a drainage chute on the top of the drainage block, and the bottom of the drainage chute being a slope with one end higher than the other.

[0007] Furthermore, the housing assembly includes a metal channel shell, on both the front and back sides of which a first connecting plate is fixedly connected.

[0008] Furthermore, bolt fixing plates are fixedly connected to the front and rear ends of the top of the metal tank shell, and a drying component is fixedly connected to the inner side of the metal tank shell.

[0009] Furthermore, a gas dispersing assembly is fixedly fitted onto the top of the metal tank shell.

[0010] Furthermore, the drying assembly includes a second connecting plate, the bottom of which is provided with a ventilation groove.

[0011] Furthermore, a connecting shaft is connected to the middle pivot at the top of the second connecting plate, and a fan is rotatably sleeved on the side of the connecting shaft.

[0012] Furthermore, the air dispersing component includes a circular top plate, and the interior of the circular top plate is provided with a one-way air pipe, one end of the one-way air pipe being three times larger than the other end.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. This utility model incorporates a conductor assembly with condensation grooves on the front and back of the conductor plate, increasing the contact area between the conductor plate and water vapor. This makes it easier for water vapor to condense into water droplets. The water droplets then flow naturally down the condensation grooves using their own weight, greatly shortening the time the water droplets stay on the conductor plate. This prevents water droplets from causing short circuits and burning out the circuit, and helps solve the problem of maintenance personnel needing to constantly monitor climate changes, which increases labor costs.

[0015] 2. This utility model has a drainage component, a bottom block is set on the inner side of the bottom of the busbar trough, and an inclined groove is opened on the top of the bottom block. The two ends of the bottom plate correspond to the two ends of the busbar trough shell. When water droplets formed by water vapor drip onto the bottom plate, they will flow from the high position to the low position along the inclined groove and finally be discharged from the busbar trough. This helps to solve the problem of the water-absorbing expansion resin absorbing moisture and the cumbersome process of needing to replace the expansion resin regularly.

[0016] 3. This utility model, by incorporating a drying component and a ventilation component, ensures that when there are small amounts of water stains in the condensate tank and the inclined tank, and residual moisture inside the busbar trunking, the moisture is insufficient to cause a short circuit when the circuit is connected. In addition, the current passing through the busbar trunking generates Joule heat, making the temperature inside the busbar trunking significantly higher than the outside temperature. The hot airflow causes the fan to rotate, accelerating the evaporation of moisture and its discharge, which further improves the moisture resistance and also enhances the heat dissipation.

[0017] 4. This utility model incorporates a ventilation component and a one-way air pipe in the ventilation top plate. One end of the one-way air pipe is small, and the other end is larger. The larger end faces the inside of the busbar trunking, and the small end faces the outside. This makes it difficult for external moisture to enter and facilitates internal airflow, thus achieving one-way flow. This helps to reduce the entry of external moisture into the busbar trunking and improves moisture resistance. Attached Figure Description

[0026] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The moisture-proof busbar trough with drainage structure involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] Reference Figures 1 to 7This utility model provides a moisture-proof busbar trunking with a drainage structure, including a conductor assembly 1, a housing assembly 3 fixedly connected to the top of the conductor assembly 1, a drainage assembly 2 fixedly connected to the inner side of the bottom of the housing assembly 3, and a venting assembly 4 fixedly connected to the top of the housing assembly 3.

[0028] In this embodiment, it is necessary to further explain that conductor assembly 1 helps to solve the problem of maintenance personnel needing to constantly monitor climate change, which increases labor costs; drainage assembly 2 helps to solve the problem of water-absorbing and expanding resin absorbing moisture, which requires the cumbersome process of replacing the expanding resin regularly; outer shell assembly 3 helps to further improve moisture resistance and also improve heat dissipation; and air dissipation assembly 4 helps to reduce the entry of external moisture into the busbar trunking and improve moisture resistance. The specific structure and working principle of the above components will be explained in detail later.

[0029] In a preferred embodiment, the conductor assembly 1 includes a conductor sheet 101, with condensation grooves 102 on both the front and back sides of the conductor sheet 101, and connection holes 103 at both ends of the conductor sheet 101.

[0030] In this embodiment, it should be specifically explained that condensation grooves 102 are provided on the front and back of the conductor sheet 101 to increase the contact area between the conductor sheet 101 and water vapor, making it easier for water vapor to liquefy into water droplets. The water droplets then flow naturally down the condensation grooves 102 using their own gravity, which greatly shortens the time that the water droplets stay on the conductor sheet 101, preventing water droplets from causing short circuits and burning out the circuit. This also helps to solve the problem of maintenance personnel needing to constantly monitor climate changes, which increases labor costs.

[0031] In a preferred embodiment, the drainage component 2 includes a drainage block 201, the top of which is provided with a drainage chute 202, and the bottom of the drainage chute 202 is a slope with one end higher than the other.

[0032] In this embodiment, it is necessary to further explain that a drainage block 201 is provided on the inner side of the bottom of the busbar trunking, and a drainage chute 202 is opened on the top of the drainage block 201. The two ends of the drainage block 201 correspond to the two ends of the busbar trunking shell. When water droplets formed by water vapor fall onto the drainage block 201, they will flow from the high position to the low position along the drainage chute 202 and finally be discharged from the busbar trunking. This helps to solve the problem of the cumbersome process of the water-absorbing expansion resin absorbing moisture and needing to replace the expansion resin regularly.

[0033] In a preferred embodiment, the outer shell assembly 3 includes a metal tank shell 301, with a first connecting plate 302 fixedly connected to both the front and back sides of the metal tank shell 301, bolt fixing plates 303 fixedly connected to both the front and rear ends of the top of the metal tank shell 301, a drying assembly 304 fixedly connected to the inner side of the metal tank shell 301, and a gas dissipation assembly 4 fixedly sleeved on the top of the metal tank shell 301.

[0034] In a preferred embodiment, the drying assembly 304 includes a second connecting plate 3041, the bottom of the second connecting plate 3041 is provided with a ventilation groove 3042, the middle pivot at the top of the second connecting plate 3041 is connected to a connecting shaft 3043, and a fan 3044 is rotatably sleeved on the side of the connecting shaft 3043.

[0035] In this embodiment, it should be specifically noted that when there are a small amount of water stains in the condensate tank 102 and the drainage sloping trough 202, and there is residual water vapor inside the busbar trunking, when the circuit is connected, this water vapor is not enough to cause a short circuit. In addition, the current passing through the busbar trunking will generate Joule heat, making the temperature inside the busbar trunking significantly higher than the outside temperature. The hot airflow causes the fan 3044 to rotate, accelerating the evaporation of water vapor and its discharge, which helps to further improve the moisture resistance and also improve the heat dissipation.

[0036] In a preferred embodiment, the air dispersing component 4 includes a circular top plate 401, and a one-way air pipe 402 is provided inside the circular top plate 401. One end of the one-way air pipe 402 is three times larger than the other end.

[0037] In this embodiment, it should be specifically explained that a one-way air pipe 402 is provided in the circular top plate 401. One end of the one-way air pipe 402 is small and the other end is larger. The larger end faces the inside of the busbar trunking and the small end faces the outside. This makes it difficult for external moisture to enter and allows the internal airflow to flow easily, thus achieving one-way flow. This helps to reduce the entry of external moisture into the busbar trunking and improve moisture resistance.

[0038] The working principle of this utility model is as follows: Condensation grooves 102 are provided on the front and back of the conductor sheet 101 to increase the contact area between the conductor sheet 101 and water vapor, making it easier for water vapor to liquefy into water droplets. The water droplets are then allowed to flow naturally down the condensation grooves 102 by their own gravity, which greatly shortens the time that the water droplets stay on the conductor sheet 101, avoids water droplets causing short circuits and burnout of the circuit, and helps to solve the problem of maintenance personnel needing to pay attention to climate change at all times, which increases labor costs.

[0039] A drainage block 201 is installed on the inner side of the bottom of the busbar trunking, and a drainage chute 202 is opened on the top of the drainage block 201. The two ends of the drainage block 201 correspond to the two ends of the busbar trunking shell. When water droplets formed by water vapor fall onto the drainage block 201, they will flow from the high position to the low position along the drainage chute 202 and finally be discharged from the busbar trunking. This helps to solve the problem of the water-absorbing expansion resin absorbing moisture and the cumbersome process of replacing the expansion resin regularly.

[0040] When there are a small amount of water stains in the condensate tank 102 and the drainage chute 202, and there is residual moisture inside the busbar trunking, the moisture is insufficient to cause a short circuit when the circuit is connected. In addition, the current passing through the busbar trunking will generate Joule heat, making the temperature inside the busbar trunking significantly higher than the outside temperature. The hot airflow causes the fan 3044 to rotate, accelerating the evaporation of moisture and its discharge, which helps to further improve moisture resistance and also improves heat dissipation. A one-way air pipe 402 is provided in the circular top plate 401. One end of the one-way air pipe 402 is small, and the other end is larger. The larger end faces the inside of the busbar trunking, and the small end faces the outside temperature, making it difficult for external moisture to enter and easy for internal airflow to circulate. This one-way circulation helps to reduce the entry of external moisture into the busbar trunking and improves moisture resistance.

[0041] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
