Description

Technical Field

[0001] The present application relates to the technical field of heat dissipation windows, and in particular to a heat dissipation window for a cable demarcation chamber. Background Art

[0002] At present, the cable demarcation chamber widely used in the power system has a large number of internal electrical components and generates a large amount of heat, which easily causes the indoor temperature to rise, thus affecting the normal operation of the equipment. In order to effectively reduce the temperature inside the cable demarcation chamber, natural ventilation holes are usually set on the wall or fans are installed for forced ventilation to achieve the purpose of cooling. Although these measures can alleviate the high temperature condition to a certain extent, there are still many limitations in actual application.

[0003] There are two common ways to dissipate heat in cable demarcation rooms. One is to allow free exchange of air between inside and outside through reserved holes in the wall, and the other is to equip electric fans to form forced convection. The former lacks an active control mechanism and may introduce problems such as rain in severe weather conditions. The latter relies on external power supply, increasing the complexity and cost burden of the system. It cannot intelligently sense the temperature difference between indoors and outdoors, making it difficult to adjust in time. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides a heat dissipation window for a cable demarcation chamber, which overcomes the deficiencies of the prior art and aims to solve the problems in the background technology.

[0005] In order to achieve the above-mentioned purpose, the present application adopts the following technical solution: a heat dissipation window for a cable boundary chamber, comprising a frame, a fixed frame is fixedly installed on the inner wall of the frame, a dustproof net is provided on the outer side of the fixed frame, a positioning frame is fixedly installed on the outer side of the dustproof net by four symmetrically installed bolts, a plurality of rotating grooves are symmetrically opened on the outer side of the frame, a rotating rod is rotatably connected to the inner wall of the rotating groove, an air guide plate is inserted into the outer edge of the rotating rod, a sprocket is fixedly installed on the outer edge of the rotating rod, a chain is provided on the outer edge of the sprocket, and the end of the rotating rod close to the sprocket is fixedly connected to the power output shaft of the stepping motor.

[0006] As a preferred embodiment, a temperature sensor and a humidity sensor are fixedly installed on the outer side of the frame, and a controller is fixedly installed on the side wall of the frame. The temperature sensor, humidity sensor and controller are electrically connected, and the controller and the stepper motor are electrically connected.

[0007] By adopting this technical solution, the indoor environmental parameters of the cable demarcation area can be monitored in real time. If the environmental parameters in the cable demarcation area exceed the set threshold, an alarm signal will be immediately triggered to the controller. The controller then promptly activates the stepper motor to slowly open the air deflector to the optimal opening and closing angle to maximize ventilation. At the same time, as fresh cold air from outside continuously flows in, the overheated air in the room is discharged outdoors, gradually returning to a safe operating range. Conversely, when the temperature drops to a predetermined range, the air inlet is closed to prevent overcooling and damage to electrical components.

[0008] As a preferred embodiment, the dustproof net is arranged in the middle position of the fixing frame and the positioning frame, and the screw rods of the four bolts pass through the positioning frame and the dustproof net to the inner wall of the fixing frame.

[0009] By adopting the above technical solution, four bolts can be used in conjunction with the positioning frame to stably position the dustproof net at the outer position of the fixed frame, and then the dustproof net can be used to filter and intercept impurities contained in the air entering the cable demarcation room, thereby preventing dust from flying into the cable demarcation room and contacting electrical components, causing damage to them.

[0010] As a preferred embodiment, there are several rotating rods, air guide plates and sprockets, and several rotating rods are rotatably connected to the inner wall of the rotating groove, and the chain is sleeved on the outer edge of several sprockets.

[0011] By adopting the above technical solution, the stepper motor drives the rotating rod to rotate and drives one of the sprockets to rotate, and then the chain can be used to drive several sprockets to rotate together, so that the angles of several air guide plates can be adjusted synchronously, thereby conveniently adjusting the ventilation effect.

[0012] As a preferred embodiment, the frame is made of aluminum alloy profiles, the air guide plates are formed by stamping stainless steel sheets, and the outer edges of the frame and the air guide plates are coated with a galvanized layer.

[0013] By adopting the above technical solution, the overall firmness can be increased to ensure that it will not be easily damaged even after long-term use. In addition, the galvanized layer can be used to coat the surface of the frame and the air guide plate with a layer of zinc to achieve an aesthetic and rust-proof effect.

[0014] As a preferred embodiment, a pentagonal column is fixedly installed on the outer edge of the rotating rod, a pentagonal hole is opened on the inner wall of the air guide plate, and the pentagonal column is inserted into the inner wall position of the pentagonal hole, and the lengths of the air guide plate and the pentagonal column are consistent with the width of the inner wall of the frame.

[0015] By adopting the above technical solution, it is easy to connect the rotating rod and the air guide plate, and to assemble the rotating rod and the air guide plate on site. The air guide plate can be replaced individually after being damaged without having to be replaced as a whole, reducing resource loss.

[0016] As a preferred embodiment, a protective cover is fixedly installed on the side of the frame close to the humidity sensor, the side of the stepper motor away from the power output shaft is fixedly connected to the inner side of the protective cover through a motor bracket, and the stepper motor, chain and several sprockets are all arranged in the inner cavity of the protective cover.

[0017] By adopting the above technical solution, the protective cover can be used to protect the stepper motor, chain and several sprockets, ensuring that they are not directly exposed to the outside, and can also play a positioning role for the stepper motor, ensuring that it will not shake easily during operation, thereby ensuring its stability during operation.

[0018] As a preferred embodiment, the inner wall diameter of the bottom of the rotation groove is consistent with the outer edge diameter of the rotation rod.

[0019] By adopting the above technical solution, the stability of the rotating rod when it is located at the inner wall of the rotating groove can be guaranteed, and it can be guaranteed that it can stably rotate to adjust the angle of the air guide plate.

[0020] Beneficial effects of this application:

[0021] 1. A heat dissipation window for a cable demarcation room monitors the indoor environmental parameters of the cable demarcation room in real time through a temperature sensor and a humidity sensor, and immediately triggers an alarm signal to a controller when it detects that the environment in the cable demarcation room exceeds a set threshold value. The controller can then promptly start a stepper motor to drive a rotating rod to rotate one of the sprockets, and then use the chain to drive several sprockets to rotate together, so that several air guide plates can be synchronously adjusted to slowly open until the optimal opening and closing angle is reached, thereby achieving maximum ventilation effect. At the same time, as fresh cold air from the outside continuously flows in, the overheated air in the room is discharged to the outside, and then gradually restored to a safe working range. Conversely, when the temperature drops to a predetermined range, the air inlet is closed to prevent excessive cooling from damaging electrical components.

[0022] 2. This heat dissipation window for the cable demarcation chamber can filter and intercept impurities contained in the air entering the cable demarcation chamber through a dustproof net, thereby preventing dust from flying into the cable demarcation chamber and contacting electrical components to cause damage.

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0030] Reference Figure 1-5 A heat dissipation window for a cable boundary room comprises a frame 1, a fixing frame 4 is fixedly installed on the inner wall of the frame 1, a dustproof net 5 is provided on the outside of the fixing frame 4, a positioning frame 6 is fixedly installed on the outside of the dustproof net 5 by four symmetrically installed bolts 7, a plurality of rotating grooves 8 are symmetrically opened on the outside of the frame 1, a rotating rod 9 is rotatably connected to the inner wall of the rotating groove 8, an air guide plate 10 is inserted into the outer edge of the rotating rod 9, a sprocket 11 is fixedly installed on the outer edge of the rotating rod 9, a chain 12 is sleeved on the outer edge of the sprocket 11, and a power output shaft of a stepping motor 13 is fixedly connected to the end of the rotating rod 9 close to the sprocket 11.

[0031] See Figure 1 A temperature sensor 2 and a humidity sensor 3 are fixedly mounted on the outside of the frame 1, and a controller is fixedly mounted on the side wall of the frame 1. The temperature sensor 2, humidity sensor 3, and controller are electrically connected, and the controller is also electrically connected to the stepper motor 13. This allows for real-time monitoring of the indoor environmental parameters of the cable demarcation area. Upon detecting that the indoor environmental parameters exceed a set threshold, an alarm signal is immediately triggered to the controller. The controller then promptly activates the stepper motor 13 to slowly open the air guide plate 10 to the optimal opening and closing angle, thereby maximizing ventilation. At the same time, as fresh cold air from outside continuously flows in, the overheated indoor air is discharged outdoors, gradually returning to a safe operating range. Conversely, when the temperature drops to a predetermined range, the air inlet is closed to prevent overcooling and damage to electrical components.

[0032] See Figure 3 and Figure 4 The dust-proof net 5 is arranged in the middle position of the fixing frame 4 and the positioning frame 6. The screws of the four bolts 7 pass through the positioning frame 6 and the dust-proof net 5 to the inner wall of the fixing frame 4, so that the four bolts 7 can be used to cooperate with the positioning frame 6 to stably position the dust-proof net 5 at the outer position of the fixing frame 4, and then the dust-proof net 5 can be used to filter and intercept impurities contained in the air entering the cable demarcation room, thereby preventing dust from flying into the cable demarcation room and contacting electrical components to cause damage.

[0033] See Figure 5 There are several rotating rods 9, air guide plates 10 and sprockets 11, and several rotating rods 9 are rotatably connected to the inner wall position of the rotating groove 8, and the chain 12 is sleeved on the outer edge position of several sprockets 11, so that the stepping motor 13 drives the rotating rod 9 to rotate and drives one of the sprockets 11 to rotate, and then the chain 12 can be used to drive several sprockets 11 to rotate together, so that the angles of several air guide plates 10 can be adjusted synchronously, thereby conveniently adjusting the ventilation effect.

[0034] See Figure 1 - Figure 3 The frame 1 is made of aluminum alloy profiles, and the air guide plate 10 is stamped by stainless steel sheets. The outer edges of the frame 1 and the air guide plate 10 are coated with a galvanized layer, which can increase their overall firmness and ensure that they will not be easily damaged even after long-term use. The galvanized layer can be used to coat the surface of the frame 1 and the air guide plate 10 with a layer of zinc to achieve beautiful and rust-proof effects.

[0035] See Figure 5 A pentagonal column is fixedly installed on the outer edge of the rotating rod 9, a pentagonal hole is opened on the inner wall of the wind guide plate 10, and the pentagonal column is inserted into the inner wall position of the pentagonal hole. The length of the wind guide plate 10 and the pentagonal column are consistent with the width of the inner wall of the frame 1, which makes it easy to connect the rotating rod 9 and the wind guide plate 10, and to assemble the rotating rod 9 and the wind guide plate 10 on the spot. The wind guide plate 10 can be replaced separately after damage without replacing the entire thing, reducing the loss of resources.

[0036] See Figure 2 and Figure 5 A protective cover 14 is fixedly installed on the side of the frame 1 close to the humidity sensor 3. The side of the stepper motor 13 away from the power output shaft is fixedly connected to the inner side of the protective cover 14 through a motor bracket. The stepper motor 13, the chain 12 and the plurality of sprockets 11 are all arranged in the inner cavity of the protective cover 14, so that the protective cover 14 can be used to protect the stepper motor 13, the chain 12 and the plurality of sprockets 11, ensuring that they are not directly exposed to the outside, and can also play a positioning role for the stepper motor 13, ensuring that it will not shake easily during operation, thereby ensuring its stability during operation.

[0037] See Figure 5 The inner wall diameter of the bottom of the rotating groove 8 is consistent with the outer edge diameter of the rotating rod 9, so that the stability of the rotating rod 9 when rotating at the inner wall position of the rotating groove 8 can be guaranteed, and it can be stably rotated to adjust the angle of the air guide plate 10.

[0038] Working principle: When using this device, the temperature sensor 2 and the humidity sensor 3 can be used to monitor the indoor environmental parameters of the cable demarcation in real time, and immediately trigger an alarm signal to the controller when it is detected that the environment in the cable demarcation exceeds the set threshold. Then the controller can promptly start the stepper motor 13 to drive the rotating rod 9 to rotate and drive one of the sprockets 11 to rotate, and then the chain 12 can be used to drive several sprockets 11 to rotate together, so that several air guide plates 10 can be synchronously adjusted to slowly open until the optimal opening and closing angle, so as to achieve the maximum ventilation effect. At the same time, as fresh cold air from the outside continues to flow in, the overheated air in the room is discharged to the outside, and then gradually returns to the safe working range. Vice versa, when the temperature drops to the predetermined range, the air inlet is closed to prevent excessive cooling from damaging electrical components, and the dustproof net 5 can be used to filter and intercept impurities contained in the air entering the cable demarcation room, thereby preventing dust from flying into the cable demarcation room and contacting electrical components to cause damage.
