Description

Technical Field

[0001] This utility model belongs to the field of power distribution technology, and specifically relates to a feeder terminal cooling device. Background Technology

[0002] A feeder terminal unit (FTU) is an automated device installed next to a pole-mounted switch on an overhead power line in a power distribution network. Its main function is to enable remote monitoring and control of the power distribution line and improve power supply reliability. In the use of feeder terminals, in order to avoid exposure to the sun in summer and the large amount of heat generated by the internal equipment, which may cause abnormal operation or damage to the feeder terminal, a feeder terminal cooling device is often required to ensure the normal operation of the feeder terminal.

[0003] Existing feeder terminal cooling devices directly install the feeder terminal module inside the chassis and then activate the cooling module within the chassis. The cooling module's air-cooling and water-cooling units stably cool the interior of the chassis, ensuring the feeder terminal module operates in a suitable environment. However, in actual use, the fixed position of the air-cooling unit's fan results in a fixed airflow range within the chassis. Consequently, parts of the chassis far from the fan's blowing area are difficult to reach with cool air, leading to uneven temperature control within the chassis. This can potentially affect the cooling effect on the feeder terminal, which can reach temperatures as high as 70-80 degrees Celsius during operation. Uneven cooling can negatively impact the feeder terminal's operating status and normal operation. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a feeder terminal cooling device that allows cold air to be blown quickly and evenly onto the feeder terminal installed in the chassis during cooling. Furthermore, the temperature of the feeder terminal can be stably and evenly controlled through the cooperation of the air-cooling unit and the water-cooling unit.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a feeder terminal cooling device, including a chassis, an air inlet seat on the upper surface of the chassis, the air inlet seat being connected to a ventilation opening on the upper surface of the chassis, an air outlet seat on the lower surface of the chassis, a filter screen one at the air inlet opening on the upper surface of the air inlet seat, a filter screen two at the air outlet opening in the middle of the lower surface of the chassis, and filter screen three at the air outlet openings on both the left and right sides of the air outlet seat, a mounting bracket inside the chassis, symmetrically distributed door panels rotating on the front side of the chassis, an air guide hood inside the chassis, the air guide hood having evenly distributed air guide holes, the air guide hood being installed in conjunction with the ventilation opening, a cooling module for cooling is also provided between the air inlet seat, the air guide hood and the air outlet seat, and an air guide module for air guiding is also provided between the air inlet seat and the air guide hood; evenly distributed fixing plates are provided on the outer side of the chassis, and rubber pads are glued and fixed to the rear side of each fixing plate.

[0006] As a further improvement of this utility model, the air-cooled module includes support plates evenly arranged inside the air inlet seat and the air outlet seat, a fan is respectively arranged between adjacent support plates, and a water-cooled module is arranged between the air inlet seat, the air guide hood and the air outlet seat.

[0007] As a further improvement of this utility model, the air guide module includes air guide grooves evenly distributed on the rear side of the air guide cover. A rotating shaft is rotatably installed inside each air guide groove, and an air guide plate is fixedly sleeved on the outer side of each rotating shaft. An electronic control unit for driving the air guide plate to swing is also provided on the air inlet seat. The electronic control unit includes a double-groove pulley fixedly sleeved on the outer arc surface of the rotating shaft. Two adjacent double-groove pulleys are respectively connected by a transmission belt. An electronic control component for driving the double-groove pulley to rotate is also provided on the air inlet seat. The electronic control component includes a mounting base set at the top of the air inlet seat. A motor is installed inside the mounting base. The output shaft of the motor is fixed to the adjacent rotating shaft by a coupling.

[0008] As a further improvement of this utility model, a control box is provided at the top center of the internal structure of the chassis, and the fan, water-cooling module and motor are all electrically connected to the control box.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] Firstly, the operation of the water-cooling module allows condensate to circulate inside, cooling the interior of the chassis.

[0011] Secondly, the upper fan draws outside air into the air inlet through the filter screen, and blows the air evenly onto the feeder terminal module through the evenly spaced air guide holes and air guide slots on the air guide cover. Then, the fan inside the air outlet exhausts the air from the filter screen, thus quickly and evenly cooling and controlling the temperature of the feeder terminal module.

[0012] Thirdly, the control box regulates the forward and reverse rotation of the motor connected to it, so that the output shaft of the motor drives the rotating shaft connected to it to rotate in the forward and reverse directions. This causes the rotating shaft to drive the air guide plate on its outer arc surface to swing back and forth, continuously guiding the air blown towards the feeder terminal module. In addition, through the cooperation of air guide holes, air guide slots and air guide plates, the cold air can be quickly and evenly blown to the feeder terminal set in the chassis when cooling the feeder terminal. Furthermore, through the cooperation of the air cooling unit and the water cooling unit, the temperature of the feeder terminal can be stably and evenly controlled.

[0013] Fourth, after passing the bolts through the mounting holes on the fixing plate, the bolts are tightened with external tools to fix the fixing plate in the designated position. The rubber pads on the fixing plate can effectively prevent damage to the fixing plate due to excessive tightening of the bolts during the installation process. Attached Figure Description

Detailed Implementation

[0020] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0021] like Figure 1 , 4 As shown, the system includes a chassis 101. An air inlet seat 102 is provided on the upper surface of the chassis 101, and the air inlet seat 102 is connected to a ventilation opening on the upper surface of the chassis 101. An air outlet seat 103 is provided on the lower surface of the chassis 101. A filter screen 105 is provided at the air inlet on the upper surface of the air inlet seat 102, a filter screen 106 is provided at the exhaust outlet in the middle of the lower surface of the chassis 101, and filters screens 107 are provided at the air outlets on both the left and right sides of the air outlet seat 103. The housing 101 has an internal mounting bracket 109. The front of the housing 101 has symmetrically distributed door panels 104. The housing 101 has an internal air guide shroud 201 with evenly distributed air guide holes 202. The air guide shroud 201 is installed in conjunction with the ventilation opening. A cooling module for cooling is also provided between the air inlet seat 102, the air guide shroud 201 and the air outlet seat 103. An air guide module for air guiding is also provided between the air inlet seat 102 and the air guide shroud 201.

[0022] like Figure 2 , 4 As shown, the air-cooled module includes support plates 203 evenly arranged inside the air inlet seat 102 and the air outlet seat 103. Fans 204 are respectively arranged between adjacent support plates 203. A water-cooled module 205 is arranged between the air inlet seat 102, the air guide hood 201 and the air outlet seat 103.

[0023] like Figure 2 , 3 As shown, the air guide module includes air guide grooves 301 evenly distributed on the rear side of the air guide cover 201. A rotating shaft 302 is rotatably mounted inside each air guide groove 301. Air guide plates 303 are fixedly sleeved on the outer surface of each rotating shaft 302. An electronic control unit for driving the air guide plates 303 to swing is also provided on the air inlet seat 102. The electronic control unit includes a double-groove pulley 304 fixedly sleeved on the outer arc surface of the rotating shaft 302. Adjacent double-groove pulleys 304 are connected by transmission belts 305. An electronic control assembly for driving the double-groove pulleys 304 to rotate is also provided on the air inlet seat 102. The electronic control assembly includes a mounting base 306 located at the top of the air inlet seat 102. A motor 307 is installed inside each mounting base 306. The output shaft of the motor 307 is fixed to the adjacent rotating shaft 302 via a coupling.

[0024] like Figure 4 As shown, a control box 401 is located at the top center of the internal top of the chassis 101. The fan 204, water-cooled module 205 and motor 307 are all electrically connected to the control box 401.

[0025] During use, the feeder terminal module is installed on the mounting bracket 109. During operation, the control box 401 regulates the operation of the fan 204 and the water-cooling module 205. The water-cooling module 205 circulates condensate within it, cooling the interior of the chassis 101. The upper fan 204 draws external air through the filter screen 105 into the air inlet 102. The air entering the air inlet 102 passes through the vents between the air guide shroud 201 and the chassis 101. The air is then evenly blown towards the feeder terminal module through the evenly spaced air guide holes 202 and air guide slots 301 on the air guide shroud 201. After passing through the feeder terminal module and the filter screen 106, the air enters the interior of the air outlet 103. The fan 204 inside the air outlet 103 then directs the air... The air discharged from filter screen 3107 provides rapid and uniform air cooling and temperature control for the feeder terminal module. The control box 401 regulates the forward and reverse rotation of the motor 307 connected to it, causing the output shaft of the motor 307 to drive the rotating shaft 302 connected to it to rotate in the forward and reverse directions. In turn, the transmission belt 305, which is set between the double-groove pulleys 304, drives all the rotating shafts 302 to rotate synchronously in the forward and reverse directions. This causes the rotating shaft 302 to drive the air guide plate 303 on its outer arc surface to swing back and forth, continuously guiding the air blown towards the feeder terminal module. In addition, through the cooperation of the air guide hole 202, the air guide groove 301 and the air guide plate 303, the cold air can be quickly and evenly blown to the feeder terminal set in the chassis when cooling the feeder terminal. In addition, the combination of the air cooling unit and the water cooling unit can stably and evenly control the temperature of the feeder terminal.

[0026] According to another embodiment of the present invention, such as Figure 1 , 2 As shown, the outer side of the chassis 101 is provided with evenly distributed fixing plates 108, and rubber pads are glued and fixed to the rear side of each fixing plate 108. When installing the chassis 101, the bolts are passed through the mounting holes on the fixing plates 108 and then the bolts are tightened by an external tool, thereby fixing the fixing plates 108 in the designated position. The rubber pads on the fixing plates 108 can effectively prevent damage to the fixing plates 108 due to excessive tightening of the bolts during the installation process.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
