Description

Technical Field

[0001] This utility model relates to the technical field of busbar trunking, and in particular to a dense busbar trunking with waterproof function. Background Technology

[0002] In modern power transmission systems, compact busbar trunking is widely used in high-rise buildings, industrial plants and other places due to its advantages such as large current carrying capacity, small size and convenient installation. However, with the continuous expansion of application scenarios, the requirements for its waterproof performance are becoming increasingly stringent. Therefore, a compact busbar trunking with waterproof function is particularly needed.

[0003] Traditional high-density busbar trunking has many limitations in terms of waterproofing. Some products are not designed with dedicated drainage channels, and the infiltrated water can easily accumulate inside the shell, directly contacting the conductors or insulation layers, causing short circuits and leakage risks. A few products with drainage functions still pose safety hazards due to unreasonable drainage paths and untimely drainage of accumulated water. In high-humidity environments such as basements and the rainy season in the south, there is a temperature difference between the inside of the busbar trunking shell and the outside, which can easily lead to condensation. The condensed water adheres to the conductor surface, which reduces the insulation resistance. Long-term accumulation may lead to insulation breakdown. If the shell is sealed too tightly, the internal moisture cannot be discharged, which will accelerate the formation of condensation and create a vicious cycle of the more sealed, the more humid it becomes.

[0004] To address the aforementioned issues, a water-resistant, compact busbar trunking system is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a compact busbar trunking with waterproof function to solve the problem of existing compact busbar trunking with waterproof function mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dense busbar trunking with waterproof function, comprising a housing, a trunking box installed on the top wall of the housing, a side guide plate integrally formed on the side wall of the housing, a moisture-absorbing module placed inside the trunking box, a gravity guide groove integrally formed on the bottom of the trunking box, a cover plate provided on the top of the moisture-absorbing module, and two sets of screws provided on both sides of the cover plate and the trunking box.

[0007] Preferably, the housing includes a top groove on its top and a bottom groove on its bottom side.

[0008] Preferably, the cover plate includes a retaining plate integrally formed at both ends of its bottom, and the retaining plate is engaged and connected to both ends of the moisture-absorbing module.

[0009] Preferably, the moisture-absorbing module is composed of porous sponge wrapped with highly absorbent resin particles.

[0010] Preferably, the bottom of the slot box has a striped gap structure, the top two sides of the slot box are placed on the top wall of the shell, and the sunken end of the slot box is located inside the top slot.

[0011] Preferably, the gravity guide channel is L-shaped, and the plane below the channel is inclined. The vertical section of the gravity guide channel is located within a rectangular space formed by the side guide plate and the shell.

[0012] Preferably, the bottom of the side guide plate passes through the bottom groove and extends to the bottom of the housing.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. It achieves rapid drainage of accumulated water through mechanical structures such as side guide plates and gravity guide channels, while using moisture absorption modules to absorb trace amounts of moisture, forming a double protection that can cope with short-term water seepage and solve the problem of condensation in long-term high humidity environments, making it suitable for humid environments; 2. The combination of the top and bottom troughs with the L-shaped gravity guide channel ensures that there is no water residue inside the shell, preventing long-term corrosion of conductors or insulating components by moisture and reducing the risk of short circuits and leakage. 3. The moisture absorption module is fixed by a clip and screws, which can be quickly replaced without disassembling the entire busbar trunking, saving maintenance time and labor costs. The moisture absorption module can be replaced without touching live parts, reducing the operation risk for maintenance personnel. Attached Figure Description

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] Example like Figure 1-6 As shown, the device includes a housing 1, a slot 2 mounted on the top wall of the housing 1, a side guide plate 3 integrally formed on the side wall of the housing 1, a moisture absorption module 4 placed inside the slot 2, a gravity guide groove 5 integrally formed on the bottom of the slot 2, a cover plate 6 provided on the top of the moisture absorption module 4, and two sets of screws 7 provided on both sides of the cover plate 6 and the slot 2. The housing 1 includes a top groove 101 opened on its top, a bottom groove 102 opened on the bottom side of the housing 1, and a retaining plate 601 integrally formed at both ends of its bottom.

[0018] It should be noted that in this embodiment, a top groove 101 is formed on the top of the housing 1, and a bottom groove 102 is formed on the bottom side. A side guide plate 3 is integrally formed on the side wall of the housing 1. The bottom of the side guide plate 3 penetrates into the bottom groove 102 and extends to the bottom of the housing 1, forming a rectangular space with the housing 1 to guide the drainage of accumulated water. The trough box 2 is installed on the top wall of the housing 1. The bottom of the trough box 2 has a striped gap structure, and the top two sides are provided on the top wall of the housing 1. The recessed end is tightly inserted into the top groove 101 to form the placement place of the moisture absorption module 4. The moisture absorption module 4 is composed of... The porous sponge is wrapped with highly absorbent resin particles and placed in the tank 2. Both ends are fixed by the clamping plates 601 of the cover plate 6. It can be replaced by removing the screws 7. The gravity guide channel 5 has an L-shaped structure and is located below the tank 2. The horizontal section is inclined and the vertical section is inserted into the rectangular space formed by the side guide plate 3 and the shell 1 to guide the water to be discharged vertically downward. The cover plate 6 is fixed to the top of the tank 2 by two sets of screws 7. The bottom clamping plate 601 is engaged with both ends of the moisture absorption module 4 to prevent the moisture absorption module 4 from shaking. The top groove 101 and bottom groove 102 of the housing 1 provide installation space for the upper and lower waterproof components, respectively. The moisture-absorbing module 4 inside the box 2, composed of porous sponge wrapped with highly absorbent resin particles, quickly absorbs condensed moisture. The cover plate 6 engages with the moisture-absorbing module 4 via a bottom clamping plate 601 and is then fixed to the box 2 with screws 7, ensuring stable installation of the moisture-absorbing module 4 and preventing displacement after moisture absorption. The drainage effect of the box 2 and the gravity drainage channel 5 further enhances the waterproofing. The striped gap structure at the bottom of the box 2 allows unabsorbed moisture to permeate into the gravity drainage channel 5 below. Since the lower plane of the gravity drainage channel 5 is inclined and L-shaped, moisture flows along the inclined plane under gravity and enters the rectangular space formed by the side guide plate 3 and the housing 1. Finally, the drainage from the side guide plate 3 completes the waterproofing loop. The bottom of the side guide plate 3 passes through the bottom groove 102 and extends to the housing 1. At the bottom, the water entering the rectangular space formed by the side guide plate 3 and the side wall of the shell 1 flows downward along the side guide plate 3 and is finally discharged outside the shell 1 through the bottom groove 102.

[0019] like Figure 4-6As shown, the bottom of the slot box 2 has a striped gap structure, the top two sides of the slot box 2 are placed on the top wall of the housing 1, and the lower end of the slot box 2 is located inside the top slot 101. The bottom of the side guide plate 3 passes through the bottom slot 102 and extends to the bottom of the housing 1.

[0020] It should be noted that in this embodiment, the installation of the slot box 2 is as follows: During installation, the flat parts on both sides of the top of the slot box 2 are first placed stably on the corresponding positions of the top wall of the housing 1. The flat structure of the top wall of the housing 1 provides a supporting foundation for the slot box 2, ensuring that the slot box 2 will not shake due to uneven force during subsequent use. Then, the lower end of the slot box 2 is precisely embedded into the preset top groove 101 of the housing 1. The size of the top groove 101 matches the size of the lower end of the slot box 2. This fitting structure further enhances the firmness of the installation of the slot box 2. At the same time, the striped gap structure at the bottom of the slot box 2 remains unobstructed after installation, reserving a channel for subsequent water infiltration and drainage. Fixing the moisture-absorbing module 4: First, align the integrated clamping plates 601 at both ends of the bottom of the cover plate 6 with the clamping slots at both ends of the moisture-absorbing module 4, and smoothly insert the clamping plates 601 into the slots. The initial fixing of the moisture-absorbing module 4 and the cover plate 6 is achieved through the clamping connection. This clamping method can quickly position the moisture-absorbing module and prevent it from shifting during the process of placing it into the slot box 2. Next, place the assembled moisture-absorbing module 4 and the cover plate 6 into the slot box 2 as a whole, ensuring that the moisture-absorbing module 4 is completely within the accommodating space of the slot box. Finally, use screws 7 to pass through the screw holes on both sides of the cover plate 6 and the slot box 2 respectively, and tighten the screws 7 to press the cover plate 6 tightly onto the slot box 2, thereby fixing the moisture-absorbing module 4 inside the slot box 2 and preventing it from shifting due to vibration and other factors during the operation of the busbar trunking.

[0021] Furthermore, the side guide plate 3 is designed to fit snugly against the side wall of the housing 1, so that together with the housing 1, they form a closed rectangular drainage space, which connects with the gravity guide channel 5 above, thus forming a continuous drainage channel from the bottom of the trough 2 to the bottom of the housing 1, ensuring that water can be discharged smoothly.

[0022] Working principle of this utility model: Refer to the instruction manual appendix Figure 1-6 In a high humidity environment, when condensation occurs inside the housing 1 due to temperature difference, the porous sponge and super absorbent resin particles of the moisture absorption module 4 can absorb the trace amount of moisture that has penetrated into the slot box 2, preventing moisture from entering the housing 1 and contacting the conductor. When the moisture absorption module 4 is saturated, the moisture absorption module 4 can be replaced by removing the cover plate 6 and the clip plate 601 to ensure long-term moisture absorption effect. When the moisture-absorbing module 4 is saturated with water, the excess water is removed from the moisture-absorbing module 4 by gravity and collects at the top of the tank 2. The striped gap structure at the bottom of the tank 2 allows water to permeate into the gravity guide channel 5 below. The inclined design of the gravity guide channel 5 causes the water to flow along the L-shaped path to the vertical section, and finally through the rectangular space formed by the side guide plate 3 and the shell 1, it is discharged outside the shell 1 through the bottom groove 102. The bottom of the side guide plate 3 extends to the bottom of the shell 1, forming a U-shaped guide channel, which uses gravity to accelerate drainage and avoid water accumulation.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
