Description

Technical Field

[0001] This utility model relates to the field of power system control equipment technology, specifically to a synchronous grid connection and closing control device. Background Technology

[0002] In power systems, the synchronous grid-connection control device is a key piece of equipment for achieving synchronous grid connection. Its load end (usually a terminal block or operating interface) is directly connected to external lines or equipment and is the core functional component of the device. Existing technology has the following problems with the protection structure of the load end of the device: Insufficient protection: Most devices have their load ends directly exposed to the outside, or are only protected by simple snap-on covers. In the exposed state, the terminals are easily deformed and the interfaces are damaged due to bumps during transportation and installation, or poor contact is caused by dust and moisture intrusion, affecting the accuracy of synchronous grid connection. After long-term use, snap-on covers are prone to loosening due to aging of the snaps, and the protective effect is greatly reduced.

[0003] Inconvenient to operate: Some protective structures use flip-up covers, which need to be completely flipped to the side of the device when opened, which can easily interfere with surrounding equipment; and there is a lack of stable positioning structure, so the cover can easily close itself due to vibration after opening, interfering with operation.

[0004] Structural interference problem: During the closure process, some sliding protective structures are prone to rigid collisions between the protrusions (such as terminals) at the load end of the device and the protective cover, which may result in the protective cover not being able to be completely closed or being damaged. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a synchronous grid-connected closing control device, which adopts the sliding cooperation of a sliding cover and a closed slide groove, combined with the guidance of a guide slide groove and a slide bar, thus solving the problems of jamming and easy interference when the protective structure is opened and closed. By fixing the positioning threaded rod to the closed threaded hole and the opening threaded hole with threads, and by fixing the movable magnetic block to the fixed magnetic block with magnetic attraction, the problem of the protective structure being not firmly fixed and easily moved accidentally is solved. The design of the flip-up enclosure plate, which automatically deflects as it follows the load end of the device, solves the problem of rigid interference between the protective cover and the load end of the device. The addition of a sealed cover solved the problem of insufficient overall protection of the control device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a synchronous grid-connected closing control device, comprising a control device; The load end of the device is fixedly connected to the front side of the control device; A sliding cover is slidably connected to the front side of the control device, and the sliding cover is used to seal and protect the load end of the device; A closed slide groove is provided on the front side of the control device, and the sliding cover is slidably connected to the inner wall of the closed slide groove.

[0007] As a preferred embodiment of this utility model, the inner wall of the closed slide groove is provided with a closed threaded hole and an open threaded hole, and the outer wall of the sliding cover near one end is provided with an installation hole, and a positioning threaded rod adapted to the closed threaded hole is movably inserted into the inner wall of the installation hole.

[0008] As a preferred embodiment of this invention, one end of the positioning threaded rod is threadedly connected to the inner wall of the closed threaded hole.

[0009] As a preferred embodiment of this utility model, the bottom and top of the inner wall of the closed slide groove are provided with guide slide grooves, and the top and top of the sliding cover are fixedly connected with slide strips adapted to the guide slide grooves.

[0010] In a preferred embodiment of this invention, the outer wall of the slide bar is slidably connected to the inner wall of the guide groove.

[0011] In a preferred embodiment of this invention, one end of the sliding cover is rotatably connected to a flip-up sealing plate, and the other end of the sliding cover is fixedly connected to a movable magnetic block. A fixed magnetic block is fixedly connected to the inner wall of the closed groove near one end, and the fixed magnetic block and the movable magnetic block are magnetically attracted to each other.

[0012] As a preferred embodiment of this invention, the control device is rotatably connected to a closed cover near the rear side of the top via a hinge.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model directly seals the load end of the device by sliding the cover, combined with the auxiliary sealing and abutment of the flip-top sealing plate, which can effectively prevent damage to the load end of the device caused by bumps, dust intrusion, and moisture erosion during transfer, idleness, or use, thus extending the service life of the device. The sealing cover further enhances the overall protection of the control device and reduces the impact of the external environment on the internal structure of the device.

[0014] 2. This utility model achieves smooth sliding of the sliding cover through the cooperation of the guide groove and the slide bar, and the opening and closing process is smooth and without jamming. When opening, it can be positioned by either the positioning threaded rod and the threaded hole of the opening threaded hole or the moving magnetic block and the fixed magnetic block of the magnetic attraction, which can adapt to different operating scenarios (such as using threaded fixation when long-term opening is required, and magnetic fixation when temporary opening is required), thus improving operating efficiency.

[0015] 3. In the closed state, the threaded connection between the positioning threaded rod and the closed threaded hole ensures that the sliding cover will not be dislodged from the closed position due to accidental factors such as vibration or collision; the double fixing method in the open state also avoids interference with the operation of the device at the load end due to accidental sliding of the sliding cover, thus ensuring operational safety.

[0016] 4. This utility model allows the flip-up sealing plate to automatically deflect according to the obstruction at the load end of the device during the opening and closing of the sliding cover, avoiding rigid interference with the load end of the device, ensuring that the sliding cover can be completely closed or opened in place, and improving the rationality of the structural fit.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0022] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0023] Example 1 Reference Figure 1-4 This is the first embodiment of the present utility model, which provides a synchronous grid-connected closing control device, including a control device 1; The load end 5 of the device is fixedly connected to the front side of the control device 1; A sliding cover 4 is slidably connected to the front side of the control device 1. The sliding cover 4 is used to seal and protect the load end 5 of the device. A closed slide 3 is provided on the front side of the control device 1, and a sliding cover 4 is slidably connected to the inner wall of the closed slide 3.

[0024] Specifically, by directly sealing the load end 5 of the device with the sliding cover 4, combined with the auxiliary sealing and abutment cooperation of the flip-up sealing plate 8, damage to the load end 5 of the device caused by bumps, dust intrusion, and water vapor erosion during transfer, idleness, or use can be effectively avoided, thus extending the service life of the device. The setting of the sealing cover 2 further enhances the overall protection of the control device 1 and reduces the impact of the external environment on the internal structure of the device.

[0025] Example 2 The second embodiment of this utility model provides a technical solution: the inner wall of the closed slide groove 3 is provided with a closed threaded hole 6 and an open threaded hole 12, and the outer wall of the sliding cover 4 near one end is provided with a mounting hole 13. A positioning threaded rod 7 adapted to the closed threaded hole 6 is movably inserted into the inner wall of the mounting hole 13. One end of the positioning threaded rod 7 is threadedly connected to the inner wall of the closed threaded hole 6.

[0026] Specifically, when opening, the device can be positioned in two ways: either by fixing the positioning threaded rod 7 to the threaded opening hole 12, or by fixing the movable magnetic block 9 to the fixed magnetic block 10. This adapts to different operating scenarios. For example, threaded fixing is used when long-term opening is required, while magnetic fixing is used when temporary opening is required, thus improving operating efficiency.

[0027] Example 3 The third embodiment of this utility model provides a technical solution: the bottom and top of the inner wall of the closed slide groove 3 are provided with guide slide grooves 11, and the top and top of the sliding cover 4 are fixedly connected with slide strips adapted to the guide slide grooves 11.

[0028] The outer wall of the slide bar is slidably connected to the inner wall of the guide groove 11.

[0029] One end of the sliding cover 4 is rotatably connected to a flip-up sealing plate 8, and the other end of the sliding cover 4 is fixedly connected to a movable magnetic block 9. The inner wall of the closed slide 3 near one end is fixedly connected to a fixed magnetic block 10, and the fixed magnetic block 10 and the movable magnetic block 9 are magnetically attracted to each other.

[0030] The control device 1 is connected to a closed cover 2 via a hinge on its rear side near the top.

[0031] Specifically, the sliding cover 4 achieves smooth sliding through the cooperation of the guide groove 11 and the slide bar, and the opening and closing process is smooth and without jamming.

[0032] Example 4 The fourth embodiment of this utility model provides a technical solution: the sliding cover 4 and the flip-up sealing plate 8 are made of high-strength insulating materials (such as ABS engineering plastic), which have both impact resistance and insulation properties, and avoid safety hazards caused by leakage at the load end of the device.

[0033] Positioning thread rod 7: Made of 304 stainless steel, it is corrosion resistant and ensures reliable threaded connection after long-term use.

[0034] Sliding bar: Made of polytetrafluoroethylene, it has a low coefficient of friction, which reduces sliding wear with the guide groove 11 and ensures smooth sliding.

[0035] Fixed magnetic block 10 and movable magnetic block 9: Neodymium iron boron permanent magnets are used to ensure that the magnetic attraction force is ≥5N, so as to prevent the sliding cover 4 from detaching from the attraction due to slight vibration after opening.

[0036] Rotational connection between the flip-up sealing plate 8 and the sliding cover 4: connected by a damping shaft (shaft diameter 5mm, damping coefficient 0.8N・m), ensuring that the flip-up sealing plate 8 can automatically reset and maintain a closed state after being obstructed and deflected.

[0037] The load end 5 of the device is a terminal block for synchronous grid connection.

[0038] Working principle: The core of this synchronous grid-connected closing control device is to achieve protection and operational coordination by using a sliding cover to close and open the load end of the device. The specific working principle is as follows: The control device 1 has a load end 5 on its front side. The sliding cover 4 is slidably connected to the front side of the control device 1 through the sealing groove 3, and is used to seal and protect the load end 5 or to open it. When the sliding cover 4 slides, the top and bottom slide strips of its top and bottom slide into contact with the guide grooves 11 at the bottom and top of the inner wall of the sealing groove 3. The guide grooves 11 limit the slide strips to achieve smooth movement of the sliding cover 4 and prevent it from deviating or getting stuck during the sliding process.

[0039] When it is necessary to close the load end 5 of the device (such as when the device is moved or idle), push the sliding cover 4 to slide along the closing groove 3 towards the load end 5 of the device. During the sliding process, the flipping closing plate 8 at one end of the sliding cover 4 will be obstructed by the load end 5 of the device and deflected until the sliding cover 4 completely covers the outer wall of the load end 5 of the device. At this time, the flipping closing plate 8 is not obstructed, resets and closes again, and abuts against the inner wall of one end of the closing groove 3, realizing the complete wrapping of the load end 5 of the device. Then, the positioning threaded rod 7 is passed through the mounting hole 13 on the outer wall of the sliding cover 4, so that one end of it is threadedly connected to the closing threaded hole 6 on the inner wall of the closing groove 3, thereby fixing the sliding cover 4 in the closed position and ensuring reliable closure.

[0040] When the load end 5 of the device needs to be opened for operation, loosen the positioning threaded rod 7 to disengage it from the closed threaded hole 6, and pull the sliding cover 4 to the right to slide along the closed slide groove 3. The slide bar moves synchronously along the guide slide groove 11. After opening to the correct position, two fixing methods can be selected: one is to thread the positioning threaded rod 7 through the mounting hole 13 and connect it to the opening threaded hole 12 on the inner wall of the closed slide groove 3 to fix the sliding cover 4; the other is to directly use the movable magnetic block 9 at the other end of the sliding cover 4 to magnetically attract the fixed magnetic block 10 near one end of the inner wall of the closed slide groove 3 to complete the positioning of the sliding cover 4. In addition, the control device 1 is connected to the rear side near the top by a hinge to a closing cover 2, which can be rotated to provide auxiliary sealing and protection for the rear side of the control device 1.

[0041] In summary: by directly sealing the load end 5 of the device with the sliding cover 4, combined with the auxiliary sealing and abutment cooperation of the flip-top sealing plate 8, damage to the load end 5 of the device caused by bumps, dust intrusion, and moisture erosion during transfer, idleness, or use can be effectively avoided, thus extending the service life of the device; the setting of the sealing cover 2 further enhances the overall protection of the control device 1 and reduces the impact of the external environment on the internal structure of the device.
