Description

Technical Field

[0001] This utility model relates to the field of power distribution room monitoring technology, specifically a monitoring device for subway power distribution rooms. Background Technology

[0002] The subway power distribution room is the place responsible for power distribution and control in the subway system. It mainly provides stable and efficient power support for subway stations and trains. During the use of the power distribution room, some of the power distribution equipment in the power distribution room will generate a certain amount of heat. If the heat is not dissipated in time, it may cause the internal components to burn out. Therefore, monitoring equipment needs to be installed to monitor the heat.

[0003] Existing power distribution room monitoring equipment, such as the one described in announcement number CN219659257U, includes a room body, in which power distribution components are fixedly connected, and further includes: a heat-conducting plate fixedly connected to the power distribution components; a temperature sensor fixedly connected to the heat-conducting plate; a monitoring box fixedly connected to the temperature sensor, with the end of the temperature sensor away from the heat-conducting plate inserted into the monitoring box; and a cooling fan rotatably connected to the room body, which transmits the heat dissipated by the power distribution components through the heat-conducting plate and the temperature sensor in the device.

[0004] The aforementioned devices rely on a relatively simple heat dissipation method during use. However, power distribution rooms typically have high-density heat dissipation areas due to the distribution of low-voltage and high-voltage equipment. Currently, the heat dissipation devices for power distribution room monitoring are integrated heat dissipation systems, which cannot meet the heat dissipation requirements of localized high temperatures. Therefore, we propose a monitoring device for subway power distribution rooms to address the aforementioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a monitoring device for subway power distribution rooms, so as to solve the problem that the existing devices mentioned in the background art have a relatively simple heat dissipation method during use, and there are usually high-density heat dissipation areas in the power distribution room due to the separation of low-voltage and high-voltage equipment. The current power distribution room monitoring heat dissipation device is an overall heat dissipation device, which cannot meet the heat dissipation needs of local high temperature.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a subway power distribution room monitoring device, comprising a power distribution room, wherein multiple power distribution devices are installed inside the power distribution room and arranged side by side, a temperature sensor is installed inside each power distribution device, an electric guide rail is provided above the power distribution devices, a main exhaust mechanism is driven and connected to the electric guide rail, an auxiliary exhaust mechanism is installed on both sides of the main exhaust mechanism, both the main exhaust mechanism and the auxiliary exhaust mechanism include a fan mounting base, a fan is installed on both sides inside the fan mounting base, and an air duct is installed at the front end of the fan, a heat dissipation hood is provided at the rear end of the power distribution room, and a guide plate is provided above the main exhaust mechanism and the auxiliary exhaust mechanism.

[0007] Preferably, the front end of the power distribution equipment is provided with a heat dissipation grille, and the top of the power distribution equipment is equipped with a top-mounted exhaust fan.

[0008] Preferably, the electric guide rail includes a guide rail base, a ball screw disposed inside the guide rail base, a stepper motor disposed at the end of the guide rail base, and a slide table that is driven and connected to the ball screw. The slide table is fixedly connected to the main exhaust mechanism, and the output end of the stepper motor is driven and connected to the ball screw.

[0009] Preferably, a slot is provided on one side of the fan mounting base, and a plug is provided on the other side of the fan mounting base. Adjacent fan mounting bases are connected by the slot and the plug. Through holes are provided on the outer wall of one side of the fan mounting base and inside the plug.

[0010] Preferably, bullseye ball bearings are installed above both ends of the fan mounting base.

[0011] Preferably, the auxiliary exhaust mechanism has support blocks at both the front and rear ends of the fan mounting base.

[0012] Preferably, the outer wall of the air hood is provided with an arc-shaped air guiding structure, and the lower end of the air hood is provided with a dust-proof and ventilation screen.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) When the power distribution room of this utility model is in use, each power distribution device is independently equipped with a temperature sensor, which can realize the temperature self-check of each power distribution device. The heat dissipation grille at the front end of the power distribution device and the top exhaust fan at the top can realize self-heating. The power distribution device is equipped with a main exhaust mechanism and an auxiliary exhaust mechanism. The main exhaust mechanism and the auxiliary exhaust mechanism are installed on the electric guide rail. Under normal conditions, the electric guide rail controls the main exhaust mechanism and the auxiliary exhaust mechanism to move to the high-density heat dissipation area of ​​the power distribution device. The fan in the main exhaust mechanism and the auxiliary exhaust mechanism work with the air hood to accelerate the exhaust efficiency of the heat dissipation area and quickly guide the heat to the heat dissipation hood. The heat is discharged by the dustproof ventilation net under the heat dissipation hood, thereby reducing the heat dissipation burden of the high-density heat dissipation area. The self-heating combined with local heat dissipation reinforcement solves the problem that the heat dissipation method of the existing device is relatively simple during use. In addition, there are usually high-density heat dissipation areas in the power distribution room due to the separation of low-voltage and high-voltage equipment. The current power distribution room monitoring heat dissipation device is an overall heat dissipation, which cannot meet the heat dissipation needs of local high temperature.

[0015] (2) Each power distribution device of this utility model is equipped with a temperature sensor. During operation, when individual equipment fails and the temperature rises abnormally, the temperature sensor of the device can feed the signal back to the controller, which will drive the electric guide rail to move the main exhaust mechanism and the auxiliary exhaust mechanism to the faulty equipment, thereby realizing the emergency heat dissipation function and reducing subsequent losses.

[0016] (3) The main exhaust system and the auxiliary exhaust system are spliced ​​structures. The number of auxiliary exhaust systems can be adjusted according to the actual range of the high-density heat-generating area, which is highly flexible. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4This utility model provides an embodiment of a subway power distribution room monitoring device, comprising a power distribution room 1, with multiple power distribution devices 2 installed inside the power distribution room 1, arranged side by side. Temperature sensors are installed inside the power distribution devices 2. An electric guide rail 3 is mounted above the power distribution devices 2, and a main exhaust mechanism 4 is driven and connected to the electric guide rail 3. Auxiliary exhaust mechanisms 5 are installed on both sides of the main exhaust mechanism 4. Both the main exhaust mechanism 4 and the auxiliary exhaust mechanisms 5 include fan mounting bases 7. Fans are installed on both sides inside the fan mounting bases 7, and a draft hood 12 is installed at the front end of each fan. A heat dissipation hood is installed at the rear end of the power distribution room 1. 6. Guide plates are provided above the main exhaust mechanism 4 and the auxiliary exhaust mechanism 5. A heat dissipation grille 201 is provided at the front end of the power distribution equipment 2. A top-mounted exhaust fan 202 is installed on the top of the power distribution equipment 2. The electric guide rail 3 includes a guide rail seat 301, a ball screw 302 provided inside the guide rail seat 301, a stepper motor provided at the end of the guide rail seat 301, and a slide table 303 that is connected to the ball screw 302. The slide table 303 is fixedly connected to the main exhaust mechanism 4. The output end of the stepper motor is connected to the ball screw 302. An arc-shaped air guiding structure 601 is provided on the outer wall of the air hood 12. A dustproof ventilation net 602 is provided at the lower end of the air hood 12.

[0024] In use, each power distribution device 2 in the power distribution room 1 is independently equipped with a temperature sensor, enabling temperature self-detection for each device. Self-heating is achieved through the heat dissipation grille 201 at the front of the device and the top-mounted exhaust fan 202. A main exhaust mechanism 4 and an auxiliary exhaust mechanism 5 are installed above the power distribution device 2, mounted on an electric guide rail 3. Under normal conditions, the electric guide rail 3 controls the main exhaust mechanism 4 and the auxiliary exhaust mechanism 5 to move to the high-density heat-generating area of ​​the power distribution device 2, where the heat is dissipated by the heat generated by the main exhaust mechanism 4 and the auxiliary exhaust mechanism 5. The fan, in conjunction with the exhaust hood 12, accelerates the exhaust efficiency of the heat-generating area, quickly guiding the heat to the heat dissipation hood 6, and then exhausting it through the dust-proof ventilation net 602 below the heat dissipation hood 6. This reduces the heat dissipation burden of the high-density heat-generating area. Since each power distribution device 2 is equipped with a temperature sensor, during operation, when an individual device malfunctions and causes an abnormal temperature rise, the temperature sensor of that device can feed back the signal to the controller. The controller then drives the electric guide rail 3 to move, causing the main exhaust mechanism 4 and the auxiliary exhaust mechanism 5 to move to the problematic device, thereby achieving emergency heat dissipation and reducing subsequent losses.

[0025] Please see Figure 3 and Figure 4A slot 9 is provided on one side of the fan mounting base 7, and a plug 10 is provided on the other side of the fan mounting base 7. Adjacent fan mounting bases 7 are connected by the slot 9 and the plug 10. Through holes 11 are provided on the outer wall of one side of the fan mounting base 7 and inside the plug 10. During the operation of the electric guide rail 3, the main exhaust mechanism 4 moves with the guide rail slide 303, while the auxiliary exhaust mechanism 5 is fixed to the main exhaust mechanism 4 by splicing and moves synchronously with the main exhaust mechanism 4. The auxiliary exhaust mechanism 5 can be flexibly adjusted according to the actual range of the high-density heat generation area.

[0026] Please see Figure 3 Bullseye balls 8 are installed above both ends of the fan mounting base 7. Guide plates are installed above the main exhaust mechanism 4 and the auxiliary exhaust mechanism 5. When the main exhaust mechanism 4 and the auxiliary exhaust mechanism 5 move under the action of the electric guide rail 3, their tops can be connected to the guide plates by the bullseye balls 8, which plays an auxiliary guiding role.

[0027] Please see Figure 4 The auxiliary exhaust mechanism 5 has support blocks 501 at both the front and rear ends of the fan mounting base 7. After the auxiliary exhaust mechanism 5 is spliced ​​with the main exhaust mechanism 4, the support blocks 501 can support the auxiliary exhaust mechanism 5 on the electric guide rail 3.
