Description

Technical Field

[0001] The utility model relates to the technical field of DCS controllers, and more specifically, to a DCS controller with a safety protection function. Background Art

[0002] A DCS controller is a control device used in the field of industrial automation to monitor and manage equipment and systems in the production process. A DCS system usually consists of multiple distributed controllers that are connected through a network and communicate with sensors, actuators and other control devices.

[0003] After searching, a Chinese patent with publication number CN213241028U discloses a DCS system terminal controller. For the existing DCS system terminal controller, the combination mode needs to be improved, the stability and reliability are not good, and in long-term use, when the equipment itself is overheated due to aging or the outside is overheated, it is easy to burn. If it cannot be handled in time, the safety of the DCS system terminal controller cannot be guaranteed, resulting in greater economic losses. Through the combined use of accessories, combined plates with combined holes are respectively installed on both sides of the shell, which has extremely high stability and reliability, and an inner frame is combined inside the shell, and the inner frame has an inclined groove. The inclined groove cooperates with the top limit plate and the bottom limit plate to clamp the compressed plate of the expanded graphite material. In the case of high temperature, the compressed plate of the expanded graphite material can expand when it encounters heat, produce a gradient release effect, fill the internal environment of the shell in multiple directions, block oxygen, reduce the risk of combustion, and have high safety.

[0004] During the use of the DCS controller, the DCS controller is directly exposed to the outside world and is easily damaged by direct collision. At the same time, some DCS controllers with protective shells have poor heat dissipation effect. At the same time, dust is easy to enter the inside. When there is a lot of dust, it is easy to form charged particles, which affects the service life of electronic components. Utility Model Content

A dust collection plate 12 is provided inside the protective shell 3, and a fixing mechanism is provided between the protective bottom plate 2 and the protective shell 3.

[0026] As attached Figure 2 As shown, a ventilation hole 13 is opened on the bottom surface of the dust collecting plate 12, and a connecting plate 14 is fixedly connected between the two ends of the dust collecting plate 12 and the inner wall of the protective shell 3, so as to facilitate the absorption of dust remaining inside the protective shell 3.

[0027] As attached Figure 1-5 As shown, the fixing mechanism includes an inner cavity 15, which is opened inside the protective shell 3, and a fixing spring 16 is fixedly connected to the top of the inner wall of the inner cavity 15, and a through slide groove 19 is opened on the front surface of the protective shell 3, and a moving card block 17 is fixedly connected to the bottom of the fixing spring 16, and the moving card block 17 is slidably connected to the inner cavity 15, and a connecting slide rod 18 is fixedly connected to the front side of the moving card block 17, and the connecting slide rod 18 is slidably connected to the through slide groove 19, and a moving block 20 is fixedly connected to the front end of the connecting slide rod 18, and the moving block 20 is movably connected to the fixed slot 21, which is convenient for fixing the protective shell 3 and the protective bottom plate 2 to prevent the protective shell 3 from opening due to collision.

[0028] As attached Figure 1-5 As shown, the number of ventilation ducts 8 and exhaust fans 9 is set to two, and the bottoms of the two ventilation ducts 8 pass through the fixed plate 6 and extend to the bottom of the fixed plate 6, so as to facilitate the exhaust fans 9 inside the ventilation ducts 8 to exhaust and dissipate heat, and the number of connecting columns 7 is set to multiple, and the multiple connecting columns 7 are evenly arranged around the bottom of the fixed plate 6 to ensure the stability of the fixed plate 6.

[0029] Working principle of the utility model: During the use of a DCS controller with a safety protection function provided by the utility model, a DCS controller body 1 is protected by a protective bottom plate 2 and a protective shell 3 to prevent the DCS controller body 1 from being exposed to the outside and easily damaged by accidental collision. At the same time, during heat dissipation, the hot air flow inside the protective shell 3 will rise, and the exhaust fan 9 installed inside the ventilation duct 8 is started, so that the hot air flow inside the protective shell 3 is discharged through the heat dissipation port 10, and the external cold air enters the protective shell 3 through the ventilation port 4, so as to prevent the temperature of the DCS controller body 1 from being too high, and provide a good heat dissipation effect while playing a protective effect. At the same time, dust is prevented by the first dustproof net 5 inside the ventilation port 4 and the second dustproof net 11 inside the heat dissipation port 10 to prevent dust from entering the protective shell 3. At the same time, a small amount of dust inside the protective shell 3 will adhere to the dust plate 12 due to air flow, effectively preventing dust from entering the DCS controller body 1 and affecting the electronic components inside it;

[0030] When fixing the protective shell 3 and the protective bottom plate 2, by pulling the moving block 20, the moving block 20 drives the connecting slide rod 18 to slide inside the through slide groove 19, thereby shrinking the moving block 17 into the inner cavity 15, and the fixing spring 16 is compressed. Then, the protective shell 3 is rotated to make the protective bottom plate 2 and the protective shell 3 form a whole, and the moving block 20 is released. The moving block 17 is inserted into the fixed groove 21 by the rebound force of the fixing spring 16 to complete the fixation.

[0031] Finally: The above embodiments are only illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
