Description
Technical Field
[0001] This utility model relates to the field of sulfur hexafluoride gas management and control technology, and in particular, to an intelligent control system for sulfur hexafluoride gas management. Background Technology
[0002] Sulfur hexafluoride (SF6) gas is widely used in power equipment (such as high-voltage switches and transformers) due to its excellent insulation and arc-quenching properties. Real-time monitoring and management of its gas status (pressure, purity, leakage, etc.) directly affects the safe and stable operation of the power system. Therefore, control systems for SF6 gas management have emerged in the industry. These systems typically include a main control unit and a display unit to achieve data acquisition, processing, and status display functions.
[0003] However, the existing control system has some structural shortcomings. Since the display unit and the main control unit are connected by a wiring harness to transmit signals and power, when a fault occurs, it is often necessary to check both and replace the damaged one. This means that during maintenance, it is often necessary to disassemble the outer casing of both units to observe, inspect, or replace them. This operation is cumbersome, time-consuming, and affects the continuity of sulfur hexafluoride gas management. Utility Model Content
[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an intelligent control system for sulfur hexafluoride gas management.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A sulfur hexafluoride gas management intelligent control system includes: a main control box with a mounting cavity having a front opening, the rear side wall of which is provided with a mounting structure for mounting a main control board; a front-protruding baffle plate is provided on the upper front side of the main control box, and the main control box is provided with a first connecting structure; a display mounting bracket having an open state and a closed state, hinged to the main control box to realize the switching between the open and closed states, the display mounting bracket having a mounting slot with an upper opening, and the display mounting bracket being provided with a second connecting structure; in the closed state, the display mounting bracket closes the front opening of the mounting cavity, the baffle plate closes the upper opening of the mounting slot, and the first connecting structure can be connected to the second connecting structure by a detachable fastener to fix the position of the display mounting bracket in the closed state; in the open state, both the upper opening of the mounting slot and the front opening of the mounting cavity are open; a display window is provided in the middle of the front side of the mounting slot; and a display module inserted into the mounting slot.
[0006] Furthermore, the thickness of the display module is less than the width of the mounting slot, the rear sidewall of the mounting cavity is provided with a clamping post, and the rear sidewall of the mounting slot is provided with a through hole for the clamping post to pass through. In the closed state, the front end of the clamping post abuts against the rear side of the display module.
[0007] Furthermore, the clamping posts are provided in four rectangular arrangement.
[0008] Furthermore, a pressure equalizing plate is sandwiched between the rear side of the display module and the rear side wall of the mounting slot, and the clamping column abuts against the rear side of the display module through the pressure equalizing plate.
[0009] Furthermore, a rubber pad is installed at the front end of the clamping column.
[0010] Furthermore, the front end of the clamping column is provided with a groove, and the rubber pad is provided with a positioning part that is embedded in the groove.
[0011] Furthermore, the rear sidewall of the mounting slot near the hinge is provided with a wire passage groove with an upper opening.
[0012] Furthermore, the display mounting bracket has a notch on the rear side of its upper end, and when closed, the shield is inserted into the notch.
[0013] Furthermore, the second connection structure is a protrusion located on the rear side wall of the display mounting bracket. The protrusion has a first connection hole. The first connection structure is a side plate on one side of the main control box. The side plate has a second connection hole. When closed, the first connection hole and the second connection hole are aligned and a detachable fastener can be installed.
[0014] Furthermore, the mounting structure is a mounting post located on the rear side wall of the mounting cavity, the mounting post has a threaded hole, and the front end of the mounting post has a positioning post, the diameter of which is smaller than that of the mounting post.
[0015] Furthermore, a clearance hole is provided in the middle of the rear side wall of the mounting slot.
[0016] This utility model has the following beneficial effects: The display mounting bracket is hinged to the main control box, allowing it to switch between open and closed states. When the system malfunctions and requires maintenance, simply removing the detachable fasteners at the first and second connecting structures switches the display mounting bracket to the open state. In this state, the openings at the top of the mounting slot and the front of the mounting cavity are open, allowing personnel to directly observe, inspect, or replace the main control board inside the mounting cavity and the display module inserted into the mounting slot. This eliminates the need to disassemble the outer casing of the display module and the main control board separately. The outer casing of the display module can be considered as a shield on the main control box, while the outer casing of the main control board is the display mounting bracket. This simplifies the maintenance process, reduces maintenance time, and effectively ensures the continuity of sulfur hexafluoride gas management. In the closed state, the display mounting bracket can close the opening on the front side of the mounting cavity, while the baffle on the front side of the upper end of the main control box can close the opening at the upper end of the mounting slot, forming a double-sealed protection and stable limiting installation for the main control board in the mounting cavity and the display module in the mounting slot, reducing the entry of external impurities; at this time, the first connection structure and the second connection structure are fixed by detachable fasteners, ensuring the stability of the structure in the closed state and improving the overall protection reliability of the system.

[0024] Please refer to Figure 1 and Figure 2 The present invention provides an intelligent control system for sulfur hexafluoride gas management, comprising a main control box 100, a display mounting bracket 200, and a display module 300.
[0025] The main control box 100 has a mounting cavity 110 with a front opening, and a mounting structure 120 is provided on the rear side wall of the mounting cavity 110 for mounting the main control board; a front-protruding baffle 130 is provided on the upper front side of the main control box 100, and a first connecting structure 140 is provided in the main control box 100.
[0026] The display mounting bracket 200 has an open state and a closed state, and is hinged to the main control box 100 to switch between the open and closed states. The display mounting bracket 200 has a mounting slot 210 with an upper opening, and a second connecting structure 220. In the closed state, the display mounting bracket 200 closes the opening at the front of the mounting cavity 110, the baffle plate 130 closes the opening at the upper end of the mounting slot 210, and the first connecting structure 140 can be connected to the second connecting structure 220 via detachable fasteners to fix the position of the display mounting bracket 200 in the closed state. In the open state, both the opening at the upper end of the mounting slot 210 and the opening at the front of the mounting cavity 110 are open. A display window 211 is provided in the middle of the front side of the mounting slot 210. The display module 300 is inserted into the mounting slot 210. In addition, the upper front side of the display mounting bracket 200 is provided with an upward protruding baffle 230. When closed, the baffle 130 fits against the baffle 230, and the baffle 230 can block the baffle 130 from the front, making the front surface of the overall structure more intact.
[0027] The present invention provides an intelligent control system for sulfur hexafluoride gas management, wherein the display mounting bracket 200 is hinged to the main control box 100, enabling it to switch between open and closed states. When the system malfunctions and requires maintenance, simply removing the detachable fasteners at the first connecting structure 140 and the second connecting structure 220 will switch the display mounting bracket 200 to the open state. At this time, the opening at the top of the mounting slot 210 and the opening at the front of the mounting cavity 110 are both open. Workers can directly observe, inspect, or disassemble and replace the main control board inside the mounting cavity 110 and the display module 300 inserted into the mounting slot 210 without having to disassemble the outer casing of the display module 300 and the main control board separately. It can be considered that the outer casing of the display module is the shielding plate 130 on the main control box 100, and the outer casing of the main control board is the display mounting bracket 200. This allows the disassembly and separation of the respective outer casings to be completed simply by switching the display mounting bracket 200 to the open state, thus opening the mounting cavity or slot for inspection or replacement. This simplifies the maintenance operation process, shortens maintenance time, and effectively ensures the continuity of sulfur hexafluoride gas management. In the closed state, the display mounting bracket 200 can close the opening on the front side of the mounting cavity 110, and at the same time, the baffle plate 130 on the upper front side of the main control box 100 can close the opening at the upper end of the mounting slot 210, forming a double-sealed protection and stable limiting installation for the main control board in the mounting cavity 110 and the display module 300 in the mounting slot 210, while also reducing the entry of external impurities; at this time, the first connecting structure 140 and the second connecting structure 220 are fixed by detachable fasteners, ensuring the stability of the structure in the closed state and improving the overall protection reliability of the system. Compared to the display module 300 being fixed to the display mounting bracket 200 with fasteners, the display module 300 is inserted into the mounting slot 210, which simplifies the disassembly and assembly of the display module 300 and facilitates its replacement later. In addition, the display window 211 in the middle of the front side of the mounting slot 210 can clearly display the monitoring data of the display module 300. The display module 300 can also be equipped with a touch screen, thereby realizing touch screen operation and control. The display window 211 does not affect the operator's viewing and operation control of the sulfur hexafluoride gas status information, thus balancing the convenience of installation and the functionality of use.
[0028] In some embodiments of this utility model, the thickness of the display module 300 is less than the width of the mounting slot 210, and both the thickness of the display module 300 and the width of the mounting slot 210 are dimensions in the front-to-back direction. When assembling or disassembling the display module 300, due to the clearance fit, the resistance is low, making assembly and disassembly smoother. A clamping post 150 is provided on the rear sidewall of the mounting cavity 110, and a through hole 212 is provided on the rear sidewall of the mounting slot 210 for the clamping post 150 to pass through. The rear sidewall of the mounting slot 210 refers to the rear sidewall in the closed state. In the closed state, the front end of the clamping post 150 abuts against the rear side of the display module 300. By using the clamping post 150 on the rear sidewall of the mounting cavity 110, which passes through the through hole 212 of the display mounting bracket 200 and abuts against the rear side of the display module 300 in the closed state, structural gaps are eliminated, installation stability is improved, and the display module 300 does not wobble significantly when touched.
[0029] In a further embodiment of this utility model, four clamping posts 150 are provided and arranged in a rectangular shape. The four clamping posts 150 can apply clamping force from four points on the rear side of the display module 300, avoiding excessive local force that could cause deformation of the display module 300. At the same time, multi-point pressure can make the display module 300 fit tightly against the inner wall of the mounting slot 210, preventing local warping and improving the installation stability of the display module 300.
[0030] Reference Figure 3 and Figure 7 In some embodiments of this utility model, a pressure equalizing plate 400 is sandwiched between the rear side of the display module 300 and the rear sidewall of the mounting slot 210, and the clamping column 150 abuts against the rear side of the display module 300 through the pressure equalizing plate 400. The addition of the pressure equalizing plate 400 between the rear side of the display module 300 and the rear sidewall of the mounting slot 210 ensures that the clamping force of the clamping column 150 is evenly transmitted to the rear side of the display module 300 through the pressure equalizing plate 400. This avoids direct contact between the clamping column 150 and the display module 300, preventing excessive local pressure and damage to the outer shell or internal components of the display module 300. The pressure equalizing plate 400 also makes the overall force on the display module 300 more balanced, improving the fixing reliability and service life of the display module 300.
[0031] Reference Figure 2 and Figure 7 In some embodiments of this utility model, a rubber pad 160 is installed at the front end of the clamping post 150. Installing the rubber pad 160 at the front end of the clamping post 150, through the elastic cushioning effect of the rubber, prevents the clamping post 150 from making hard contact with the display module 300 or the pressure equalizing plate 400, thus protecting the appearance and structural integrity of the display module 300. Additionally, due to manufacturing and assembly considerations, the distance between the clamping post 150 and the display module 300 in the off state may not be the same for every system; there is usually a certain degree of error, and the distance between different systems may fluctuate slightly. The elastic deformation capacity of the rubber can adapt to these fluctuations in distance.
[0032] Reference Figure 7 In a further embodiment of this utility model, the front end of the clamping column 150 is provided with a groove 151, and the rubber pad 160 is provided with a positioning part 161 that is embedded in the groove 151. By embedding the positioning part 161 into the groove 151, the rubber pad 160 is positioned and installed. The positioning part 161 is usually in an interference fit with the groove 151, which can improve the installation stability of the rubber pad. Of course, for installation stability, the rubber pad and the clamping column 150 can also be bonded together with adhesive.
[0033] Reference Figure 2 and Figure 6 In some embodiments of this utility model, a cable tray 213 with an upper opening is provided on the side of the rear wall of the mounting slot 210 near the hinge. The cable tray 213 provides a dedicated wiring channel for the wiring harness between the display module 300 and the main control board. The cable tray 213 can regulate the routing of the wiring harness, and its proximity to the hinge prevents the wiring harness from being excessively pulled during the hinge movement of the display mounting bracket 200, avoiding damage or breakage of the wiring harness when the display mounting bracket 200 switches states, thus ensuring stable signal and power transmission. At the same time, the upper opening of the cable tray 213 facilitates the installation and maintenance of the wiring harness, improving the convenience of wiring operations. Specifically, the hinge position of the main control box 100 and the display mounting bracket 200 is on the left side, and the cable tray 213 is located on the left side of the rear wall of the mounting slot 210, close to the hinge, reducing the pulling or squeezing of the wiring harness when the display mounting bracket 200 hinges. It is understandable that, in order to avoid the equalizing plate 400 from blocking the wire passage 213, the equalizing plate 400 can be provided with a relief groove or notch corresponding to the wire passage 213, or the left and right dimensions of the equalizing plate 400 can be designed to be smaller than the left and right dimensions of the mounting slot 210 in order to avoid the wire passage 213.
[0034] Reference Figure 2In some embodiments of this utility model, the second connecting structure 220 is a protrusion located on the rear sidewall of the display mounting bracket 200, which refers to the rear sidewall in the closed state. The protrusion has a first connecting hole 221, and the first connecting structure 140 is a side plate on one side of the main control box 100. The side plate has a second connecting hole 141. In the closed state, the first connecting hole 221 and the second connecting hole 141 are aligned, allowing for the installation of detachable fasteners. Precise connection is achieved through hole alignment, ensuring the stability of the display mounting bracket 200 in the closed state. The fastener can be a screw, the first connecting hole 221 can be a threaded hole, and the second connecting hole 141 can be a through hole. Typically, for ease of operation, the protrusion is located on the side away from the hinge, and the side plate is also located on the side away from the hinge, i.e., the first connecting structure 140 is the right side plate of the main control box 100. The protrusion is located at the right edge of the rear sidewall of the display mounting bracket 200 in the closed state. In addition, to prevent the bump from interfering with the side panel as it rotates with the display mounting bracket 200, there will be a gap between the bump and the corresponding side panel when the display is closed.
[0035] Reference Figure 4 and Figure 5 In some embodiments of this utility model, the mounting structure 120 is a mounting post located on the rear side wall of the mounting cavity 110. The mounting post has a threaded hole 121 at its center and a positioning post 122 at its front end. The threaded hole 121 passes through the positioning post 122, and the diameter of the positioning post 122 is smaller than that of the mounting post. The positioning post 122 can be inserted into the positioning hole of the main control board for quick positioning. Because the diameter of the positioning post 122 is smaller than that of the mounting post, the main control board will be in contact with the mounting post, creating a gap between the main control board and the rear side wall of the mounting cavity 110. This prevents components on the rear side of the main control board from being pressed and also improves heat dissipation on the rear side of the main control board. Screws can be installed in the threaded hole 121 to fix the main control board to the mounting post. Multiple mounting posts can be spaced apart to achieve multi-position mounting and fixing of the main control board in multiple locations.
[0036] Reference Figure 2 and Figure 6In some embodiments of this utility model, a clearance hole 214 is provided in the middle of the rear side wall of the mounting slot 210. The clearance hole 214 assists in heat dissipation from the rear of the display module 300, preventing heat from accumulating in the mounting slot 210 and allowing it to diffuse to the rear mounting cavity 110. This avoids performance degradation or malfunction of the display module 300 due to poor heat dissipation during long-term operation, thereby improving the service life and operational stability of the display module 300. It is understood that a corresponding clearance heat dissipation hole 410 also needs to be provided in the center of the equalizing plate 400. It is understood that when the operating power consumption of the main control board and the display module 300 is high, heat dissipation holes can be provided on the side wall of the main control box 100. If an active cooling fan is installed on the main control board or the main control box 100, heat dissipation holes can be provided on the main control box 100 according to the position of the cooling fan. If the operating power consumption of the main control board and the display module 300 is low, heat dissipation holes may not be provided to reduce the entry of dust and impurities.
[0037] Specifically, the main control box 100 has a first hinge post on its left side, and the display mounting bracket 200 has a corresponding second hinge post on its outer side. The first and second hinge posts have corresponding holes for hinged connection via hinge shafts. In some embodiments, a handle may also be provided on the side of the display mounting bracket 200 away from the hinge for easy operation; of course, since the display mounting bracket 200 needs to install the display module and has a certain thickness, in some other embodiments, the display mounting bracket 200 may not have a handle and can still be easily operated by rotating the display mounting bracket 200 along the hinge.
[0038] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
