Description

Technical Field

[0001] The utility model belongs to the field of grounding line selection devices, and in particular relates to a small current grounding line selection device for an industrial computer. Background Art

[0002] In the power system, the grounding of equipment is to ensure the safe operation of the system and prevent electrical equipment and personnel from receiving electric shock due to faults. The small current grounding line selection device is a device used to detect grounding faults in the power system. It is particularly sensitive to the detection of small current grounding faults. Compared with the small current grounding line selection devices used in communication base stations and electrical equipment in detection buildings, the small current grounding line selection devices used by industrial computers have a more severe operating environment. For example, during the oil and gas exploration stage of an oil field, it may be necessary to deploy it together with the industrial control system in a hot outdoor desert environment. The desert has a high temperature during the day, which can easily cause heat accumulation inside the device.

[0003] However, existing small current line selection devices usually lack heat dissipation devices. When deployed in the field with industrial computers during oil and gas exploration, they need to withstand high ambient temperatures, which can easily cause heat accumulation inside the equipment. Excessive temperature will reduce the performance of internal electronic components, damage the detection sensitivity of the device, and even reduce its service life.

[0004] Therefore, in view of the problem that the above-mentioned small current line selection device lacks a heat dissipation device and needs to be deployed in a high temperature environment in the field during oil and gas exploration, which causes heat accumulation inside the equipment and leads to a degradation of the performance of electronic components, damages the detection sensitivity of the device and even reduces the service life, a small current grounding line selection device for an industrial computer is developed. By adding a circulating liquid cooling system to the small current line selection device, the device is cooled, the ambient temperature of the internal electronic components is lowered, the detection performance of the device is improved, and the damage to the internal components caused by high temperature is reduced. Utility Model Content

[0005] In order to overcome the lack of heat dissipation devices in small current line selection devices, when oil and gas exploration is deployed in high-temperature outdoor environments, it is easy to cause heat accumulation inside the equipment, reducing the performance of electronic components, damaging detection sensitivity and even reducing the service life of the device.

[0006] The technical solution of the utility model is: a small current grounding line selection device for an industrial computer, comprising a line selection device body, a dust shield structure, a sealing ring structure, a shield fixing component, a water circulation component, a wind cooling component, and a heat dissipation fin structure. A dust shield structure is arranged on the outer side of the wiring terminal on the back side of the line selection device body, a sealing ring structure is fixedly connected to the side of the dust shield structure, a shield fixing component is arranged on the side of the dust shield structure, a water circulation component with an external water tank is arranged around the outer side of the line selection device body, a wind cooling component is arranged inside the water tank of the water circulation component, and a plurality of heat dissipation fin structures are arranged on the outer side of the wind cooling component.

[0007] Preferably, a dustproof shield structure is used to shield the wiring port with a cover-like structure to prevent external dust from entering and causing blockage. The sealing ring structure seals the data cable outlet portion with a soft sealing sleeve tied with a strap to prevent dust from entering the shield from the lead-in port. The shield fixing assembly is fixed by bolts to prevent the shield from loosening due to external force when closed, resulting in gaps that allow external dust to enter. The water circulation assembly continuously delivers cold water in the cold water tank into a heat exchange box surrounding the line selection device body through a water pump, thereby continuously taking away the heat of the line selection device body. The heated water is circulated back to the cold water tank and passes through the wind cooling assembly, which uses a fan to accelerate the air flow. The circulating hot water is cooled and then output by cooperating with the heat dissipation fin structure to increase the contact area between the cold water tank and the air, thereby ensuring the supply of cooling water and jointly cooling the line selection device body to prevent heat accumulation inside the device from damaging the performance and life of electronic components.

[0008] Preferably, the dustproof cover structure includes a dustproof cover and a wire threading port. The dustproof cover is connected to the wiring point on the back of the line selection device body by rotating a shaft. A number of wire threading ports are opened on the side of the dustproof cover. The wiring ports are shielded by the dustproof cover to prevent external sand and dust from entering the wiring ports and causing blockages that affect data transmission effects and even damage data connectors. The wire threading ports are convenient for leading out the connected data cables.

[0009] Preferably, the sealing ring structure includes a silicone sealing sleeve and a binding groove. A silicone sealing sleeve with a matching shape is fixedly connected to the outside of the threading port. An annular binding groove is provided on the side of the silicone sealing sleeve. The soft silicone sealing sleeve is tightened by wrapping the binding groove with a binding belt. The elasticity of the sealing sleeve is used to deform and fit the surface of the data cable to block small gaps, thereby preventing external sand and dust from entering through the gaps in the threading port and protecting the data interface and data connector.

[0010] Preferably, the baffle cover fixing assembly includes a fixing plate and a fixing bolt. A fixing plate with a screw hole is fixedly connected to the side of the line selection device body. The fixing plate is located on the side of the dust cover. The inner side of the screw hole of the fixing plate is screwed with a fixing bolt. The end of the fixing bolt is screwed and installed in the screw hole on the side of the dust cover. The closed dust cover is fixed by passing the fixing bolt through the fixing plate and the dust cover in sequence to prevent it from loosening due to external force when closed, exposing a gap to allow dust to enter, thereby protecting the data interface and data connector.

[0011] Preferably, the water circulation component includes a heat exchange box, a cooling water storage box, and a circulation pipe. The outer side of the line selection device body is wrapped with a heat exchange box with a hollow interior. A cooling water storage box containing a circulating water pump is arranged on the side of the heat exchange box. A circulation pipe is fixedly connected between the cooling water storage box and the heat exchange box. The circulating water pump in the cooling water storage box transports the cooling water through the circulation pipe to the heat exchange box wrapped around the line selection device body to take away the heat. The heated cooling water is then circulated back to the cooling water storage tank for cooling to perform a cooling cycle, thereby cooling the line selection device body, improving the sensitivity of the device and extending the service life of the electronic components.

[0012] Preferably, the air cooling component includes a central air duct and a cooling fan. A central air duct is opened through the side of the cooling water storage tank, and cooling fans are embedded at both ends of the central air duct. The cooling fan increases the air flow speed in the central air duct, thereby accelerating the cooling speed of the hot water in the cooling water storage tank, and cooling the parts of the cooling water storage tank that are not easily contacted with the air, thereby improving the cooling effect of the water circulation system.

[0013] Preferably, a plurality of uneven heat dissipation fin structures are fixedly connected to the outside of the air cooling component, and all the heat dissipation fin structures are arranged at equal intervals. The heat dissipation fin structures increase the contact area with the air to accelerate the cooling speed of the hot water in the cooling water storage tank, thereby improving the cooling effect of the water circulation.

[0014] Beneficial effects of the utility model:

[0015] 1. The dustproof cover structure uses a cover-like structure to cover the wiring port to prevent external dust from entering and causing blockage. The sealing ring structure seals the data cable outlet part through a soft sealing sleeve tied with a strap to prevent dust from entering the cover from the lead-in port. The cover fixing assembly fixes the cover by bolts to prevent it from loosening due to external force when closed, resulting in gaps for external dust to enter. The water circulation assembly continuously sends cold water in the cold water tank into the heat exchange box surrounding the line selection device body through a water pump, continuously taking away the heat of the line selection device body, and the heated water is circulated back to the cold water tank. The wind cooling assembly uses a fan to accelerate the air flow, and cooperates with the heat dissipation fin structure to increase the contact area between the cold water tank and the air to cool the circulating hot water and then output it, ensuring the supply of cooling water, and jointly cooling the line selection device body to prevent heat accumulation inside the device from damaging the performance and life of electronic components.

[0016] 2. The accumulated heat inside the line selection device body is circulated and exchanged by circulating water cooling, so as to reduce the ambient temperature of the electronic components inside the line selection device body, reduce high temperature damage and increase the life of the electronic components.

[0017] 3. Use the middle air duct to dissipate heat from the part of the circulating water cooling coolant storage tank that is least likely to come into contact with the air, thereby improving the cooling efficiency of the coolant and thus improving the heat dissipation effect of the circulating water cooling.

[0018] 4. Use a dust cover and a silicone sealing sleeve to shield the wiring of the line selection device to prevent sand from the desert from drifting into the wiring terminal and clogging or damaging the wiring port. BRIEF DESCRIPTION OF THE DRAWINGS

A plurality of uneven heat dissipation fin structures 7 are fixedly connected to the outer side of the wind cooling component 6. All the heat dissipation fin structures 7 are arranged at equal intervals.
