Description

Technical Field

[0001] This utility model belongs to the field of power distribution terminals, specifically referring to a dustproof FTU power distribution terminal with a cover. Background Technology

[0002] With the advancement of smart grid construction, the FTU (Field-Turns-Off Terminal) is a crucial component of distribution network automation, and its operational reliability directly impacts power supply quality. Currently, outdoor FTUs commonly face problems of dust accumulation and poor heat dissipation, which can easily lead to equipment failure over long-term operation. Statistics show that environmental factors account for approximately 35% of all FTU failures annually, with dust contributing over 60% of these. Traditional protective measures struggle to address both dust prevention and heat dissipation requirements, necessitating the development of novel protective technologies.

[0003] The existing technologies mainly employ three solutions: the first is a completely sealed enclosure design, which achieves dust prevention by adding sealing strips, but this leads to the accumulation of internal heat; the second is an open heat dissipation design, which sets up ventilation holes in conjunction with dust filters, but the dust prevention effect is limited and requires frequent maintenance; the third is an active cooling system, which uses fans for forced convection, but it has high energy consumption and cannot effectively prevent dust from entering when the fans are not working. Utility Model Content

[0004] The present invention mainly addresses the aforementioned technical problems.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows: The dustproof FTU power distribution terminal proposed by this utility model includes a box, a door hinged to the front of the box, and a rainproof plate fixed to the upper part of the box. Its characteristic is that it also includes a blower, an exhaust fan, a connection port, and a movable baffle.

[0006] An air intake chamber is provided on the lower part of one side of the box, and a ventilation grille is provided at the connection between the air intake chamber and the inside of the box. An exhaust chamber is provided on the upper part of the other side of the box, and a ventilation grille is also provided at the connection between the exhaust chamber and the inside of the box.

[0007] The blowing device is located on the lower inner side of the air inlet chamber, and the exhaust device is located on the upper inner side of the exhaust chamber.

[0008] There are two sets of connection ports. One set of connection ports is located inside the air intake chamber and between the ventilation grille and the blower. The other set of connection ports is located inside the exhaust chamber and between the ventilation grille and the exhaust device.

[0009] The movable baffle is located inside the connection port and is slidably connected to the connection port.

[0010] Furthermore, the blower includes an air inlet, a blower fan, and a filter plate. The air inlet is located on the lower part of the inner side of the air inlet chamber, and the blower fan is located on the air inlet and directly below the connection port.

[0011] Furthermore, a sliding groove is provided directly below the air intake chamber, the sliding groove is located at the bottom of the box, and the filter plate and the sliding groove are slidably fitted together.

[0012] Furthermore, the ventilation device includes an exhaust port and an exhaust fan. The exhaust port is located inside the exhaust chamber, and the exhaust fan is located on the exhaust port and directly below the connection port.

[0013] Furthermore, the movable baffle is formed by a top plate, a connecting column, and a limiting ring fixedly connected from top to bottom, and the whole is made of foam material.

[0014] Furthermore, the top plate has a circular plate structure with a diameter larger than the diameter of the connection port. The top plate is located above the connection port and is movably fitted to the connection port. A sealing rubber gasket is provided at the connection point.

[0015] Furthermore, both ends of the connecting column are connected to the top plate and the limiting ring respectively, and the connecting port is movable through the connection.

[0016] Furthermore, the limiting ring is designed as an annular plate structure and is movably abutting against the lower part of the connection port.

[0017] The beneficial effects of this utility model by adopting the above structure are as follows:

[0018] 1. The dustproof FTU power distribution terminal proposed in this solution, by setting the movable baffle and connection port as movable connections, can be controlled to open and close during the cooling process of the exhaust fan and blower fan, thus achieving an organic combination of dust prevention and heat dissipation. The movable baffle structure automatically closes the connection port when not dissipating heat, effectively preventing dust from entering.

[0019] 2. The dustproof FTU power distribution terminal proposed in this solution adopts a dual-fan convection design, which improves heat dissipation efficiency and can control the internal temperature of the enclosure within an ideal range.

[0020] 3. The dustproof FTU power distribution terminal proposed in this solution features a modular design that facilitates maintenance. In particular, the sliding installation method of the filter plate greatly simplifies the cleaning and replacement process. Moreover, the overall structure is simple and reliable, and the connection port can be automatically opened and closed without the need for an additional control mechanism.

[0028] like Figure 1-4 As shown, the present invention proposes a dustproof FTU distribution terminal with a cover, including a box 1, a door 101 hinged to the front of the box 1, a rain shield 102 fixed on the upper part of the box 1, and also including a blower 2, an exhaust device 3, a connection port 4 and a movable baffle 5; an air intake chamber 103 is opened on the lower part of one side of the box 1, and a ventilation grille 104 is opened at the connection between the air intake chamber 103 and the interior of the box 1; an exhaust chamber 105 is opened on the upper part of the other side of the box 1, and the exhaust chamber 105 and the interior of the box 1 are connected. Ventilation grille 104 is also provided at the connection point; blower 2 is located on the lower inner side of air intake chamber 103, and exhaust device 3 is located on the upper inner side of exhaust chamber 105; there are two sets of connection ports 4, one set of connection ports 4 is located on the inner side of air intake chamber 103 and between ventilation grille 104 and blower 2, and the other set of connection ports 4 is located on the inner side of exhaust chamber 105 and between ventilation grille 104 and exhaust device 3; movable baffle 5 is located inside connection port 4 and is slidably connected to connection port 4.

[0029] like Figure 1-4As shown, the blower 2 includes an air inlet 201, a blower 202, and a filter plate 204. The air inlet 201 is located on the lower part of the inner side of the air inlet chamber 103. The blower 202 is located on the air inlet 201 and directly below the connection port 4. It is used to draw in low-temperature air from the outside. A sliding groove 203 is provided directly below the air inlet chamber 103. The sliding groove 203 is located at the bottom of the housing 1. The filter plate 204 and the sliding groove 203 are slidably fitted together to block dust mixed in the outside air. It is also convenient to remove and replace the filter plate 204. The exhaust device 3 includes an exhaust port 301 and an exhaust fan 302. The exhaust port 301 is located on the inner side of the exhaust chamber 105. The exhaust fan 302 is located on the exhaust port 301 and directly below the connection port 4.

[0030] like Figure 1-4 As shown, the movable baffle 5 is formed by a top plate 501, a connecting column 502, and a limiting ring 503 fixedly connected from top to bottom. The whole is made of foam material, which is lightweight. The top plate 501 has a circular plate structure and its diameter is larger than the diameter of the connecting port 4. The top plate 501 is located above the connecting port 4 and is movably fitted to the connecting port 4. A sealing rubber gasket is provided at the connection.

As exhaust fan 302 blows air upwards, movable baffle 5 floats up and opens connection port 4. At this time, high-temperature air is discharged along connection port 4, completing heat exchange and cooling. The overall structure is simple, and the opening and closing of connection port 4 can be controlled by exhaust fan 302 and blower fan 202 during the heat dissipation process, making operation convenient.
