Description

Technical Field

[0001] This invention relates to the field of electrical equipment technology, specifically to a switch cabinet with a temperature monitoring mechanism. Background Technology

[0002] Switchgear with integrated temperature monitoring mechanisms enables real-time monitoring and control of the temperature of key internal components, ensuring the safety and stability of the switchgear during operation. It plays an important role in power distribution systems and is widely used in various power distribution systems, such as power plants, substations, and industrial plants.

[0003] However, existing switchgear with temperature monitoring mechanisms still has some problems in use:

[0004] An existing switch cabinet with monitoring function, such as Chinese patent application number 201520126646.4, includes a humidity sensor, a temperature sensor, a central controller, an SMS sending module, an automatic power-off switch, and an automatic fire extinguisher. Door status monitoring switches are installed on the switch cabinet body and door to detect the door's status. The nozzle of the automatic fire extinguisher is equipped with a solenoid valve. The humidity sensor, temperature sensor, and door status monitoring switch are connected to the central controller and transmit the detection signals to the central controller in real time. The central controller controls the SMS sending module, the automatic power-off switch, and the solenoid valve on the automatic fire extinguisher. Its structure is simple, easy to use and install, simple to operate, and low in cost. It can monitor the working status inside the switch cabinet in real time, automatically extinguish a fire in the switch cabinet, automatically disconnect the circuit inside the switch cabinet when the switch cabinet is flooded, and also alarm when someone damages the electrical facilities inside the switch cabinet.

[0005] 1. Although existing switch cabinets have temperature detection functions, they are usually designed in a closed manner to ensure electrical safety. This structure restricts the natural flow of air, which makes it easy for the temperature inside the cabinet to rise. High temperature environment will have an adverse effect on the current carrying capacity of the switching components and conductors inside the cabinet, and may even affect the stable operation and life of the equipment. In addition, when the temperature inside the cabinet is too high, heat will easily accumulate inside the cabinet, leading to short circuit problems in the circuit.

[0006] 2. The existing switch cabinets have filters installed at the ventilation points. Although these filters can block some dust from entering the cabinet, it is not convenient to scrape, clean, and collect the dust from the ventilation filters. As a result, after long-term use, dust can easily accumulate on the ventilation filters, leading to reduced ventilation efficiency and exacerbating the problem of increased temperature inside the cabinet.

[0007] 3. Existing switch cabinets can usually only be inspected by opening the cabinet door. This method requires power outage during the inspection process and may involve complex disassembly and installation processes. It is not only time-consuming and labor-intensive, but may also increase operational risks. In addition, the space is small, making it difficult for staff to work inside the cabinet and making it inconvenient to inspect components and wiring.

[0008] To address the aforementioned issues, an innovative design was implemented based on the existing switchgear equipped with a temperature monitoring mechanism. Summary of the Invention

[0009] The purpose of this invention is to provide a switch cabinet with a temperature monitoring mechanism to solve the problems mentioned in the background art, which are that although existing switch cabinets have temperature detection functions, they cannot dissipate heat from the inside of the cabinet, and the space is small, making it inconvenient for staff to inspect the inside of the cabinet.

[0010] To achieve the above objectives, the present invention provides the following technical solution: a switch cabinet with a temperature monitoring mechanism, comprising a cabinet body, one end of which is connected to a cabinet door via a hinge, and an observation window is provided on the outer surface of the cabinet door, a monitoring host is provided on the outside of the cabinet door, an alarm device is provided on the outside of the cabinet door, and a temperature sensor is provided at the top of the cabinet body.

[0011] The cabinet has through slots on both sides, and a connecting plate is connected to one side of the cabinet via a hinge. The connecting plates are symmetrically arranged about the central axis of the cabinet. Both connecting plates have air outlets inside. An air intake fan is installed inside the cabinet near the left air outlet, and an air outlet fan is installed inside the cabinet near the right air outlet. A filter is fixedly connected to the outside of the air outlet.

[0012] The observation window is located on the outer surface of the cabinet door, allowing for easy observation of the interior without opening the door. The temperature sensor is installed at the top inside the cabinet, sensing the internal temperature and monitoring it in real time. The temperature sensor then transmits the temperature data to the monitoring host for analysis and processing. The monitoring host has a display screen that shows the temperature value. When the temperature is too high, an alarm device will sound to remind staff to perform maintenance. The monitoring host can control the intake and exhaust fans to rotate synchronously, ensuring air circulation inside the cabinet. A filter is installed at the air outlet to block impurities in the air and prevent dust from entering the cabinet.

[0013] Preferably, the outer ends of both the inlet fan and the outlet fan are connected to a first pulley assembly, and a support rod is fixedly connected to the top of the first pulley assembly.

[0014] Using the above technical solution, the air inlet fan and the air outlet fan can drive the first pulley group and the support rod to rotate respectively when they rotate.

[0015] Preferably, one end of the support rod is connected to a scraper, and one end of the scraper is provided with a scraping brush, which is in close contact with the filter screen.

[0016] Using the above technical solution, when the support rod rotates, it can drive the scraper and the scraper to rotate synchronously, and the scraper is in close contact with the filter screen. When the scraper rotates, it can scrape off the dust from the filter screen.

[0017] Preferably, the outer ends of both the inlet fan and the outlet fan are connected to a second pulley assembly, and the bottom end of the second pulley assembly is connected to a connecting rod.

[0018] Using the above technical solution, the intake fan and the exhaust fan can drive the second pulley group to rotate synchronously when they rotate.

[0019] Preferably, a piston pump is installed on the outer side of both connecting plates, and one end of the connecting rod is connected to the inside of the piston pump through a bearing.

[0020] Using the above technical solution, one end of the connecting rod rotates inside the piston pump.

[0021] Preferably, a piston rod is sleeved on the outside of the connecting rod, and a piston plate is connected to the top of the piston rod.

[0022] Using the above technical solution, when the connecting rod rotates, it can drive the piston rod and piston plate to move vertically inside the piston pump.

[0023] Preferably, the piston pump has a dust suction port on its top and a dust outlet on the top of one side of the piston pump. Both the dust suction port and the dust outlet are equipped with a one-way valve. A dust collection box is provided on one side of the piston pump. The dust collection box is symmetrically arranged about the central axis of the cabinet. A dust suction pipe is connected between the dust outlet and the dust collection box.

[0024] Using the above technical solution, the dust suction port on the top of the piston pump can draw dust into the interior of the piston pump, and then discharge the dust into the interior of the dust collection box through the dust outlet and dust suction pipe, thereby facilitating the collection of dust.

[0025] Preferably, a drive motor is installed on the top of the cabinet, and the output end of the drive motor is connected to a first threaded rod.

[0026] Using the above technical solution, the drive motor serves as the power source, and upon restarting, it can drive the first threaded rod to rotate.

[0027] Preferably, a third pulley set is externally connected to the output end of the drive motor, and a second threaded rod is connected to the right end of the third pulley set.

[0028] Using the above technical solution, when the drive motor starts, its output end can drive the third pulley group to rotate, and the third pulley group can drive the second threaded rod connected to the right end to rotate synchronously.

[0029] Preferably, the cabinet body is internally fixedly connected with limit rods, and the limit rods are symmetrically arranged about the central axis of the cabinet body. The two limit rods are slidably connected to fixed plates. The two fixed plates are respectively threaded to the first threaded rod and the second threaded rod. The two fixed plates are hinged to the connecting plate with fixed rods, and two sets of fixed rods are symmetrically arranged about the central axis of the cabinet body.

[0030] Using the above technical solution, when the fixed plate moves up and down, it can move along the limiting rod to ensure that no deviation occurs during the movement. When the first threaded rod and the second threaded rod rotate, they can drive the fixed plate to move up and down respectively. Furthermore, a fixed rod is hinged between the fixed plate and the connecting plate. When the fixed plate moves, it can drive the fixed rod to move, which can adjust the angle of the connecting plate and ensure the stability and reliability of the structure during the adjustment process.

[0031] Compared with the prior art, the beneficial effects of the present invention are as follows: The switch cabinet with a temperature monitoring mechanism, through the cabinet body, cabinet door, observation window, monitoring host, warning device, temperature sensor, connecting plate, air outlet, inlet fan and outlet fan, allows the temperature sensor to sense the temperature inside the cabinet. The temperature sensor then transmits the temperature data to the monitoring host, which is equipped with a display screen to display the temperature value. When the temperature value is too high, the warning device can issue an alarm. The monitoring host can control the inlet fan and outlet fan to rotate synchronously. The inlet fan can send air into the cabinet through the air outlet, and the outlet fan can exhaust the hot air inside the cabinet through another air outlet. Filters are installed at the air outlets to block impurities in the air, thereby achieving temperature monitoring while simultaneously dissipating heat from the cabinet.

[0032] 1. The system consists of a first pulley assembly, support rod, scraper, scraper brush, second pulley assembly, connecting rod, and piston pump. When the inlet and outlet fans rotate, they drive the first and second pulley assemblies to rotate synchronously. This causes the first pulley assembly to drive the support rod and scraper to rotate synchronously. When the scraper and scraper brush contact the filter screen, they can remove dust from the outer surface of the filter screen. When the second pulley assembly rotates, it drives the connecting rod to rotate, causing the piston rod and piston plate to move vertically inside the piston pump. This allows the piston pump to draw the cleaned dust into the pump, and then the dust is transported to the dust collection box through the dust suction pipe. This facilitates the cleaning of the filter screen and the collection of dust, preventing filter screen clogging and improving heat dissipation efficiency.

[0033] 2. Through the configured drive motor, first threaded rod, third pulley group, second threaded rod, limit rod, fixing plate, and fixing rod, when the monitoring host detects that the cabinet temperature is too high and a short circuit has occurred, it can control the drive motor to start. When the output end of the drive motor drives the third pulley group, first threaded rod, and second threaded rod to rotate, the fixing plate, which is threaded to the first and second threaded rods respectively, can move up and down. This causes the fixing plate to drive the fixing rod to move and push the connecting plate to rotate around the hinge seat as the axis, thereby adjusting the angle of the connecting plate. When the connecting plate rotates upward, it is convenient for operators to inspect and repair the electronic components and circuits inside the cabinet. Attached Figure Description

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Please see Figure 1-8 This invention provides a technical solution: a switch cabinet with a temperature monitoring mechanism, comprising a cabinet body 1, a cabinet door 2 connected to one end of the cabinet body 1 via a hinge, an observation window 3 provided on the outer surface of the cabinet door 2, a monitoring host 4 provided on the outer side of the cabinet door 2, an alarm device 5 provided on the outer side of the cabinet door 2, and a temperature sensor 6 provided at the top of the cabinet body 1. Through slots are provided on both sides of the cabinet body 1, and a connecting plate 7 is connected to one side of the cabinet body 1 via a hinge seat. The connecting plate 7 is symmetrically arranged about the central axis of the cabinet body 1. Air outlets 8 are provided inside both connecting plates 7. An intake fan 9 is installed inside the cabinet body 1 near the left air outlet 8, and an exhaust fan 10 is installed inside the cabinet body 1 near the right air outlet 8. A filter screen 11 is fixedly connected to the outer side of the air outlet 8. The observation window 3 is located on the outer surface of the cabinet door 2 for easy observation. Without opening cabinet door 2, the internal condition of the cabinet can be observed. Temperature sensor 6 is installed at the top inside cabinet 1 to sense the internal temperature and monitor it in real time. Temperature sensor 6 then transmits the temperature data to monitoring host 4. Monitoring host 4 is equipped with a display screen to show the temperature value. When the temperature value is too high, alarm device 5 can sound an alarm. Monitoring host 4 can control the intake fan 9 and exhaust fan 10 to rotate synchronously. Intake fan 9 can send air into the interior of cabinet 1 through air outlet 8, and exhaust fan 10 can exhaust the hot air inside cabinet 1 through another air outlet 8. Filter screens 11 are installed at each air outlet 8 to block impurities in the air and protect intake fan 9 and exhaust fan 10 from damage. This achieves both temperature monitoring and heat dissipation of cabinet 1.

[0045] Both the inlet fan 9 and the outlet fan 10 are connected to the outer ends of a first pulley assembly 12. A support rod 13 is fixedly connected to the top of the first pulley assembly 12. A scraper 14 is connected to one end of the support rod 13, and a scraper brush 15 is provided at one end of the scraper 14. The scraper brush 15 is in close contact with the filter screen 11. Both the inlet fan 9 and the outlet fan 10 are connected to the outer ends of a second pulley assembly 16. A connecting rod 17 is connected to the bottom end of the second pulley assembly 16. Piston pumps 18 are installed on the outer sides of both connecting plates 7. One end of the connecting rod 17 is connected to the inside of the piston pump 18 through a bearing. A piston rod 19 is sleeved on the outside of the connecting rod 17, and a piston plate 20 is connected to the top of the piston rod 19. A dust suction port 21 is opened on the top of the piston pump 18, and a dust outlet 22 is opened on the top of one side of the piston pump 18. A dust collection box 24 is provided on one side of the piston pump 18, and the dust collection box 24 is symmetrically arranged about the central axis of the cabinet 1. A suction pipe 23 connects the dust outlet 22 to the dust collection box 24. When the inlet fan 9 and the outlet fan 10 rotate, they can drive the first pulley group 12 and the second pulley group 16 to rotate synchronously. This causes the first pulley group 12 to drive the support rod 13 and the scraper 14 to rotate synchronously. When the scraper 14 and the scraper brush 15 come into contact with the filter screen 11, they can remove the dust on the outer surface of the filter screen 11. When the second pulley group 16 rotates, it can drive the connecting rod 17 to rotate, and drive the piston rod 19 and the piston plate 20 to move vertically inside the piston pump 18. This allows the piston pump 18 to suck in the cleaned dust, and then the dust is transported to the dust collection box 24 through the suction pipe 23. Both the suction port 21 and the dust outlet 22 are equipped with one-way valves to facilitate the cleaning of the filter screen 11 and the collection of dust, preventing the filter screen 11 from becoming clogged and improving the heat dissipation efficiency.

[0046] A drive motor 25 is installed on the top of the cabinet 1, and the output end of the drive motor 25 is connected to a first threaded rod 26. A third pulley group 27 is connected to the outside of the output end of the drive motor 25, and a second threaded rod 28 is connected to the right end of the third pulley group 27. Limiting rods 29 are fixedly connected inside the cabinet 1, and the limiting rods 29 are symmetrically arranged about the central axis of the cabinet 1. Fixing plates 30 are slidably connected to the outside of both limiting rods 29. The two fixing plates 30 are threadedly connected to the first threaded rod 26 and the second threaded rod 28, respectively. Fixing rods 31 are hinged between the two fixing plates 30 and the connecting plate 7, and two sets of fixing rods 31 are symmetrically arranged about the central axis of the cabinet 1. When the monitoring host 4 detects that the temperature of the cabinet 1 is too high and a short circuit occurs in the circuit, it can control the drive motor. When the drive motor 25 starts, the output end of the drive motor 25 drives the third pulley group 27, the first threaded rod 26, and the second threaded rod 28 to rotate. The fixed plate 30, which is threadedly connected to the first threaded rod 26 and the second threaded rod 28 respectively, can move up and down. The fixed plate 30 is sleeved on the outside of the limiting rod 29, so that the fixed plate 30 can move along the limiting rod 29 when it moves. When the fixed plate 30 moves, it can drive the fixed rod 31 to move. The fixed rod 31 is hinged to the connecting plate 7, and the connecting plate 7 is connected to the cabinet 1 through the hinge seat. The fixed rod 31 can push the connecting plate 7 to rotate around the hinge seat as the axis, thereby adjusting the angle of the connecting plate 7. When the connecting plate 7 rotates upward, it is convenient for the operator to inspect and repair the electronic components and circuits inside the cabinet 1.
