Description

[Technical Field]

[0001] The present invention relates to the technical field of control cabinets, and particularly to control cabinets with temperature alarm devices. [Background technology]

[0002] A control cabinet is a device that centrally controls and protects electrical equipment. It can operate and manage equipment in a centralized manner, and has overload and short circuit protection and status monitoring functions, and some can also be remotely controlled.

[0003] Temperature-controlled control cabinets are commonly used as electrical control cabinets. Electrical control cabinets accommodate switchgear, measuring instruments, electrical equipment, and auxiliary equipment in a metal cabinet according to the wiring requirements of electrical equipment, allowing for easy inspection without endangering the safety of personnel or surrounding equipment. A search revealed that prior art application number CN202122662177.6 describes a temperature-controlled control cabinet, including a control cabinet body, in which various electrical equipment is installed. The control cabinet body is also equipped with a temperature and humidity inspection unit, a master unit, an automatic cooling unit, and an abnormality alarm unit. The temperature and humidity inspection unit inspects the temperature and humidity conditions within the control cabinet and transmits the detected temperature information to the master unit. The master unit receives temperature information from the temperature and humidity inspection unit and drives the automatic cooling unit to control the temperature and the abnormality alarm unit to issue an alarm. The parameter setting unit sets the parameter information of the control cabinet. The automatic cooling unit controls the temperature of the control cabinet. The abnormality alarm unit is used to issue an alarm when an abnormal temperature occurs. The present invention can accurately detect the temperature and humidity inside the control cabinet body, automatically control the temperature and humidity, and issue sound and light alarms in the event of an abnormality.

[0004] However, while conventional control cabinets with temperature control functions achieve both temperature control and high temperature warning functions, they have the following drawbacks. Conventional control cabinets generally use a heat dissipation fan attached to the case to dissipate heat, but the area of the fan mounting holes is generally not very large (making them easy to dustproof), the amount of ventilation inside the cabinet is low, and heat dissipation is slow despite the high temperatures inside the cabinet. Next, some conventional technologies involve installing large water-cooled heat dissipation devices or high-power fans inside the cabinet, but these heat dissipation devices have the drawbacks of being expensive to purchase and consuming a lot of power. Summary of the Invention [Problem to be solved by the invention]

[0005] In view of the problems of the prior art described above, the present invention provides a control cabinet with a temperature alarm device to address the shortcomings of the prior art control cabinets described in the background art. These shortcomings are as follows: Conventional control cabinets generally use a heat dissipation fan attached to the case to dissipate heat, but the area of the fan mounting hole is generally not very large (making it easy to protect against dust), the amount of ventilation inside the cabinet is low, and heat dissipation is slow when the cabinet is hot. Second, some prior art systems use large water-cooled heat dissipation devices or high-power fans inside the cabinet, but these heat dissipation devices have the disadvantages of being expensive to purchase and consuming a lot of power. [Means for solving the problem]

[0006] To achieve the above object, the present invention provides a control cabinet with a temperature alarm device, which includes: Cabinet case: A control panel is attached to the top of the cabinet case, an audible and visible alarm is attached to the top of the cabinet case, and heat dissipation fans are attached to both sides of the cabinet case; Cabinet door: installed on the front of the cabinet case, the cabinet door is attached to both sides of the front of the cabinet case via a hinge structure, the cabinet door is positioned below the control panel, a spring is connected to the inner wall of the cabinet door, the other end of the spring is connected to the inner wall of the cabinet case, and a first electric push rod is attached to the inside of the cabinet door; Ventilation holes: installed on both sides of the cabinet case, a ventilation assembly is provided outside the ventilation holes, the exterior of the ventilation assembly is an outer frame body, a slide plate is slidably inserted inside the outer frame body, and a second electric push rod is connected to the upper end of the slide plate; Temperature and humidity sensor: Installed on the inner wall of the cabinet case, a master controller is attached to the inner wall of the cabinet case, a signal receiving module is provided to the right of the master controller, and a wireless communication module is provided to the right of the signal receiving module.

[0007] Preferably, the heat dissipation fan is mounted on a heat dissipation hole on the surface of the cabinet case, and the heat dissipation hole is located above the ventilation assembly. The heat dissipation fan is normally on, but the ventilation hole is closed to prevent dust from entering when the temperature inside the cabinet case is within a safe range, and is only opened when the temperature inside the cabinet case rises rapidly due to the external environment or internal electrical operation.

[0008] Preferably, the temperature and humidity sensor is electrically connected to the first electric push rod and the second electric push rod through the master controller, and a temperature alarm is realized by the temperature and humidity sensor and an audible and visible alarm.

[0009] Preferably, the first electric push rod is provided below the ventilation opening, and a piston rod end of the first electric push rod is connected to a rubber ball head, which is directed toward the cabinet door. By providing a rubber ball head at the tip of the first electric push rod, damage to the cabinet door due to abrasion impact when the first electric push rod comes into contact with the cabinet door can be prevented.

[0010] Preferably, the outer frame body has a rectangular frame body structure, and both the length and width of the rectangular frame body are larger than the ventilation opening, chutes are provided on the inner frame walls on both sides of the outer frame body, a rectangular hole is provided at the upper end of the outer frame body, and a dustproof net is provided on the outside of the slide plate, and the dustproof net covers the outside of the outer frame body.

[0012] Compared with the prior art, the present invention provides a control cabinet with a temperature alarm device, which has the following beneficial effects:

[0013] 1. The temperature alarm control cabinet detects temperature and humidity using a temperature and humidity sensor, and the master controller drives the heat dissipation device assembly, i.e., the ventilation assembly and the first electric push rod. This activates the second electric push rod included in the ventilation assembly, causing the sliding plate to be pulled up from the outer frame, further opening the ventilation port and increasing the air inflow and outflow rate. At the same time, the first electric push rod is driven to push the cabinet door outward, and the spring action pulls the cabinet door back, causing the cabinet door to swing like a fan blade, matching the large-area ventilation port, thereby achieving the effect of quickly dissipating heat from the cabinet, improving heat dissipation efficiency and reducing the operating costs of the heat dissipation device.

[0014] 2. This temperature alarm control cabinet electrically connects a signal receiving module to the outside of the master controller to activate the audible and visual alarms to achieve the audible and visual alarm effect, and also transmits high temperature signals to mobile phones and PC terminals via wireless communication modules and communication networks. If the audible and visual alarms are disabled, they can be used to promptly notify the administrator and allow the administrator to check the operating status of the heat dissipation device in a timely manner.

[0016] The technical means in the embodiments of the present invention will be described below clearly and completely with reference to the drawings of the embodiments of the present invention, but it is clear that the described embodiments are only some of the embodiments of the present invention and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without any creative work fall within the scope of protection of the present invention.

[0017] The present invention provides a control cabinet with a temperature alarm device. Referring to Figure 1, the cabinet includes a cabinet case 1, a cabinet door 14, a ventilation hole 16, and a temperature and humidity sensor 19. A control panel 11 is attached to the top of the cabinet case 1, an audible and visual alarm 12 is attached to the top of the cabinet case 1, and heat dissipation fans 13 are attached to both sides of the cabinet case 1. The cabinet door 14 is installed on the front of the cabinet case 1, and is attached to both sides of the front of the cabinet case 1 via a hinge structure. Referring to FIG. 2 , the cabinet door 14 is located below the control panel 11, and a spring 15 is connected to the inner wall of the cabinet door 14, the other end of which is connected to the inner wall of the cabinet case 1, and a first electric push rod 17 is attached to the inside of the cabinet door 14.

[0018] The two first electric push rods 17 inside the cabinet door 14 are capable of synchronous retraction movement, and also capable of alternating telescopic movement, in which one cabinet door 14 closes while the other opens.

[0019] Ventilation openings 16 are provided on both sides of the cabinet case 1. Referring to Fig. 1, a ventilation assembly 2 is provided outside the ventilation openings 16. Referring to Fig. 3, the exterior of the ventilation assembly 2 is an outer frame body 24, a slide plate 23 is slidably inserted inside the outer frame body 24, and a second electric push rod 22 is connected to the upper end of the slide plate 23.

[0020] Referring to Figure 2, the temperature and humidity sensor 19 is installed on the inner wall of the cabinet case 1, a master controller 3 is attached to the inner wall of the cabinet case 1, a signal receiving module 31 is provided to the right of the master controller 3, and a wireless communication module 32 is provided to the right of the signal receiving module 31.

[0021] Referring to FIG. 1, the heat dissipation fan 13 is attached to the heat dissipation hole on the surface of the cabinet case 1, and the heat dissipation hole is located above the ventilation block 2. The heat dissipation fan 13 is turned on, but the ventilation port 16 is closed to prevent dust from entering when the temperature inside the cabinet case 1 is within a safe range, and is only opened when the temperature inside the cabinet case 1 rises rapidly due to the external environment or internal electrical operation.

[0022] Referring to FIG. 2, the temperature and humidity sensor 19 is electrically connected to the first electric push rod 17 and the second electric push rod 22 via the master controller 3, and a temperature alarm is realized by the temperature and humidity sensor 19 and the audible and visible alarm 12.

[0023] The temperature and humidity sensor 19 detects the humidity, and the control unit of the master controller 3 drives the heat dissipation device assembly, i.e., the ventilation assembly 2 and the first electric push rod 17. By operating the second electric push rod 22 included in the ventilation assembly 2, the slide plate 23 is pulled upward from the outer frame 24, further opening the ventilation opening 16 and increasing the air flow rate. At the same time, the first electric push rod 17 is driven to push the cabinet door 14 outward, and the spring 15 pulls the cabinet door 14 back, causing it to swing like a fan blade, aligning with the large-area ventilation opening 16 and achieving the effect of quickly dissipating heat from the cabinet, improving heat dissipation efficiency and reducing the operating costs of the heat dissipation device.

[0024] Referring to FIG. 4, a signal receiving module 31 is electrically connected to the outside of the master controller 3 to drive the audible and visual alarm 12 to realize the audible and visual alarm effect, and a high temperature signal is transmitted to a mobile phone or PC terminal via the wireless communication module 32 and the communication network. If the audible and visual alarm 12 alarm is disabled, it is used to promptly notify the administrator, and the operating status of the heat dissipation device can be checked in a timely manner.

[0025] 2, the first electric push rod 17 is provided below the ventilation opening 16, and a rubber ball head 18 is connected to the piston rod end of the first electric push rod 17. The rubber ball head 18 faces the cabinet door 14. By providing the rubber ball head 18 at the front end of the first electric push rod 17, damage to the cabinet door 14 due to abrasive impact when the first electric push rod 17 comes into contact with the cabinet door 14 is prevented.

[0026] Referring to Figure 3, the outer frame body 24 has a rectangular frame structure, and both the length and width of the rectangular frame body are larger than the ventilation opening 16. Chutes 25 are provided on the inner frame walls on both sides of the outer frame body 24, a rectangular hole is provided at the upper end of the outer frame body 24, and a dustproof net 26 is provided on the outside of the slide plate 23, and the dustproof net covers the outside of the outer frame body.

[0027] The second electric push rod 22 is fixed vertically to the outer wall of the cabinet case 1, and a mounting block 21 is attached to the bottom of the second electric push rod 22, and the mounting block 21 is welded to the outer wall of the cabinet case 1.

[0028] In this proposal, first, by installing a slide plate 23, the ventilation opening 16 is closed when not in use to prevent the intrusion of dust, and at the same time, it has an excellent protective effect in that it prevents the dustproof net 26 from being bent inward due to a direct external collision to the outside of the ventilation opening 16.

[0029] During use, if the temperature inside the control cabinet becomes too high, it is first detected by the temperature and humidity sensor 19, which is then electrically connected to the first electric push rod 17 and the second electric push rod 22 via the master controller 3, and a temperature warning is realized by the temperature and humidity sensor 19 and the audible and visual alarm 12.

[0030] The temperature and humidity sensor 19 detects the humidity, and the control unit of the master controller 3 drives the heat dissipation device assembly, i.e., the ventilation assembly 2 and the first electric push rod 17. By operating the second electric push rod 22 included in the ventilation assembly 2, the slide plate 23 is pulled upward from the outer frame 24, further opening the ventilation opening 16 and increasing the air flow rate. At the same time, the first electric push rod 17 is driven to push the cabinet door 14 outward, and the spring 15 pulls the cabinet door 14 back, causing it to swing like a fan blade, aligning with the large-area ventilation opening 16. This achieves the effect of quickly dissipating heat from the cabinet case 1, improving heat dissipation efficiency and reducing the operating costs of the heat dissipation device.

[0031] The control cabinet with temperature alarm of the present invention effectively solves the problems of the heat dissipation devices connected to conventional control cabinets with temperature alarms, such as the slow heat dissipation efficiency or high operating costs. In addition to the technology of conventional control cabinets with temperature alarms, it avoids the need to purchase and use expensive heat dissipation equipment and instead utilizes the structure of the control cabinet itself to improve the heat dissipation efficiency of the control cabinet, and is particularly used when the temperature inside the control cabinet rises rapidly and requires immediate heat dissipation.
