DETAILED DESCRIPTION

[0023] The following specific embodiment explains the embodiment of the utility model of the person skilled in the art can easily understand the other advantages and efficacy of the utility model from the content disclosed in the specification, obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor belong to the scope of the utility model protection.

[0024] Combined with reference Figures 1-5 The utility model provides a kind of equipment temperature control alarm device, including air duct 1, the outer surface of air duct 1 is fixedly connected with equipment mounting ring 2.

[0025] The equipment temperature control alarm device of the present application is mainly applied to electrical equipment to control the temperature of electrical equipment, so the side of the electrical equipment needs to be provided with a slot for the air duct 1 to pass through. The equipment mounting ring 2 is provided with mounting holes that can be connected to the electrical equipment with bolts. This can stabilize the position of the air duct 1.

[0026] In this embodiment, one end of the air duct 1 is provided with an exhaust fan 3.

[0027] The exhaust fan 3 is a Panasonic FV-17CU7C, with a size of 300*300mm. By starting the exhaust fan 3, the air inside the electrical equipment can be introduced into the air duct 1. By detecting the temperature of the air in the air duct 1, the running temperature of the electrical equipment can be monitored.

[0028] In this embodiment, one end of the air duct 1 is fixedly connected with an assembly plate 7, and the exhaust fan 3 is connected to the assembly plate 7 by bolts.

[0029] The assembly plate 7 can provide mounting support for the exhaust fan 3 at one end of the air duct 1. The exhaust fan 3 can be easily disassembled by being connected to the assembly plate 7 by bolts.

[0030] In the embodiment, the assembly plate 7 is provided with a stepped groove, and the stepped groove is provided with a dust screen 8.

[0031] The stepped groove is communicated with the air duct 1, so that the exhaust fan 3 can perform negative pressure operation on the air duct 1, and the dust screen 8 can be connected on the stepped groove through screws, so that the dust screen 8 can be conveniently disassembled and assembled. Since the dust screen 8 can achieve the dust prevention effect, the detection end of the temperature sensor 41 extending into the air duct 1 can prevent dust interference and ensure the accuracy of temperature detection.

[0032] In the embodiment, the air duct 1 is provided with a temperature sensing alarm structure 4, which includes a temperature sensor 41 and an audible and light alarm 42. The temperature sensor 41 and the audible and light alarm 42 are both fixedly connected to the outer surface of the air duct 1, and the detection end of the temperature sensor 41 extends into the air duct 1.

[0033] The temperature sensor 41 is a 3435 NTC thermistor sensor, which has small volume, fast response and low cost. The audible and light alarm 42 is a TBJ-150 type, which has waterproof, moisture-proof and impact-resistant properties. In the present application, at least two temperature sensors 41 are provided, and the two temperature sensors 41 are symmetrically arranged on the air duct 1. The purpose of providing two temperature sensors 41 is that when the exhaust fan 3 introduces air in a specified area of the electrical equipment into the air duct 1, the two temperature sensors 41 can simultaneously detect the temperature of the air in the air duct 1. Two temperature data provided by the two temperature sensors 41 are averaged, so that the accuracy of the final temperature data can be improved. The two temperature sensors 41 can be electrically connected to the audible and light alarm 42 through the existing controller. The alarm temperature threshold can be set through the controller. When the temperature sensor 41 detects that the air temperature introduced into the air duct 1 is high, the controller can control the audible and light alarm 42 to remind the user. The control circuit of the controller can be realized by simple programming of those skilled in the art, and the power supply is also a common knowledge in the art.

[0034] It is worth noting that since the temperature sensor 41 detects the temperature of the air flowing in the air duct 1, in order to avoid the influence of wind speed on the temperature response, timeliness and accuracy of the temperature sensor 41, the power of the exhaust fan 3 should be set to control the air speed entering the air duct 1 to be less than 1 m / s.

[0035] In the embodiment, the other end of the air duct 1 is provided with a universal bamboo joint pipe 5, and the end of the universal bamboo joint pipe 5 away from the air duct 1 is fixedly connected with a wind guide cover 6 communicated therewith.

[0036] The universal bamboo joint pipe 5 is connected by a plurality of small joints to form a bendable and shaped structure similar to bamboo. The universal bamboo joint pipe 5 is made of POM material. The universal bamboo joint pipe 5 is a general standard part or a component known to those skilled in the art, which can be directly purchased on the market. When it is necessary to monitor the electrical components in the specified area of the electrical equipment, the universal bamboo joint pipe 5 is pulled to adjust the path and angle of the universal bamboo joint pipe 5 to direct the opening of the air inlet hood 6 to the vicinity of the electrical components, so that the air near the electrical components can be introduced into the air duct 1 through the air inlet hood 6 and the universal bamboo joint pipe 5 in sequence when the exhaust fan 3 is working. The temperature sensor 41 can detect the temperature of the air in the air duct 1, and the audible and visual alarm 42 can alarm according to the temperature data.

[0037] In this embodiment, the outer side of the universal bamboo joint pipe 5 is covered with a heat preservation layer 9.

[0038] The heat preservation layer 9 uses heat preservation cotton as a heat preservation material to perform heat preservation treatment on the universal bamboo joint pipe 5. The air flowing in the universal bamboo joint pipe 5 can be heat preserved to avoid loss of heat in the air in the universal bamboo joint pipe 5. This can make the temperature sensing alarm structure 4 more direct and accurate in detecting the temperature of the specified area in the electrical equipment.

[0039] In this embodiment, the inner side of the air inlet hood 6 is provided with a dust screen 10.

[0040] The dust screen 10 is connected to the air inlet hood 6 by screws. When the air inlet hood 6 inhales the working temperature of the specified area in the electrical equipment, the dust screen 10 can prevent dust from entering the air duct 1 through the universal bamboo joint pipe 5. The dust screen 10 can further protect the temperature sensor 41.
