Description

Technical Field

[0001] The present invention relates to the technical field of emergency power supplies, and particularly to a rapid access device for emergency power supplies used in substations. Background Art

[0002] With the rapid development of society and the progress of technology, people's dependence on electricity is increasing day by day. If a substation experiences a power outage due to reasons such as line maintenance, line faults, or component damage, it will have a great impact on the lives and production of electricity customers. Therefore, how to provide high-reliability high-quality power supplies is a major issue faced by power supply enterprises, posing new challenges to the technological innovation of the distribution network. And a rapid access device for emergency power supplies can effectively improve power supply reliability, enhance power supply service quality, reduce economic losses, and improve economic and social benefits.

[0003] When the existing rapid access device for emergency power supplies is in use, the device body is directly moved and carried. When it rains, rainwater easily enters the interior of the device body, causing damage to the electronic components inside the device body, affecting the service life, and the placement position is fixed. When emergency charging needs to be carried out for substations in different locations, it requires staff to carry it again, increasing human output and reducing the practicality of use. Also, when in use, the heat dissipation effect is poor, and the internal equipment cannot be effectively cooled. Excessive heat cannot be discharged in time, which will damage the internal equipment and affect the normal use of the emergency equipment. To address the above problems, the existing equipment needs to be improved.

[0004] Therefore, there is an urgent need for a rapid access device for emergency power supplies used in substations to solve the above technical problems. Summary of the Invention

[0007] Furthermore, a movable guide rail is provided on the upper side wall of the support base plate, and the device body is mounted on the movable guide rail. Two ends of the movable guide rail point to the opening and the shock absorbing mechanism respectively, so the device body can only move on the movable guide rail.

[0008] Furthermore, the heat dissipation mesh plate includes a first heat dissipation mesh plate and a second heat dissipation mesh plate, the second heat dissipation mesh plate is arranged at the upper end of the device body, the side wall of the device body is provided with a removable inspection cover, and the second heat dissipation mesh plate is arranged on the inspection cover, so the heat dissipation mesh plates are respectively arranged on the top and side walls of the device body, which facilitates air convection, is conducive to the rapid circulation of heat, and improves the heat dissipation effect.

[0009] Furthermore, a frequency converter and an input / output device are also provided inside the device body, and a control panel, a connecting socket and a display rack are provided on the device body near the opening side, the display rack is located between the control panel and the connecting socket, the connecting socket is connected to one end of the connecting wire through a plug connector, the other end of the connecting wire passes through the display rack and is connected to the connecting clamp terminal, and the display rack is also provided with an extension seat for placing the connecting clamp, and the setting of the display rack facilitates the limiting and guiding of the connecting wire to avoid entanglement.

[0010] Furthermore, the shock absorbing mechanism includes a fixed side plate, a buffer connection assembly and a magnetic block magnetically connected to the fixed side plate, the fixed side plate is arranged on the side wall of the device body, the buffer connection assembly is connected between the fixed side plate and the inner side wall of the device body, the magnetic block is arranged on the outer side wall of the device body and corresponds to the buffer connection assembly, the magnetic block can attract the fixed side plate so that the device body on the movable guide rail is close to the shock absorbing mechanism, and when the device box vibrates, the shock absorbing mechanism provides buffering for the device body, thereby improving the practicality of the device.

[0011] Further, the buffer connection component includes a sleeve, a fixed insertion rod, and a buffer spring. One end of the fixed insertion rod is slidably disposed inside the sleeve, and the other end passes through the sleeve and is connected to the inner side wall of the device box. A buffer spring is sleeved outside the fixed insertion rod between the device box and the sleeve.

[0012] Further, the heat dissipation mechanism includes a first driving motor disposed on the inner top wall of the device box. Limiting frames are symmetrically arranged on both sides of the first driving motor. An installation frame is rotatably disposed between the lower ends of the two limiting frames. A second driving motor is movably disposed inside the installation frame. A rotating connection member is connected between the upper end of the second driving motor and the output shaft of the first driving motor. A plurality of fan blades are installed on the output shaft at the lower end of the second driving motor. The first driving motor is used to drive the second driving motor to swing cyclically, so as to expand the heat dissipation area of the second driving motor. During the rotation of the second driving motor, different positions inside the device box are dissipated heat, greatly improving the heat dissipation effect.

[0013] Further, the opening and closing mechanism includes a horizontal seat disposed on the outer side wall of the device box. Two moving sliding frames are symmetrically and slidably disposed on the outer side of the horizontal seat. The lower ends of the two moving sliding frames are respectively connected to the left door panel and the right door panel through corresponding first connecting plates. An installation bracket is disposed on one side of the moving sliding frame above the left door panel. A first gear and a second gear are installed on the installation bracket. The upper end of the second gear is engaged with a first rack fixedly disposed on the outside of the device box. The upper end of the first gear is engaged with a second rack. The lower end of the other side of the second rack is slidably connected to a chute opened on the inner side of the upper end of the first rack through a slider. The lower end of one side of the second rack is also connected with a second connecting plate. The lower end of the second connecting plate is connected to the moving sliding frame above the right door panel.

[0014] Further, the first gear is located outside the second gear, and the diameter of the first gear is larger than that of the second gear. The first gear and the second gear are coaxially installed for synchronous rotation. The size difference between the first gear and the second gear needs to be determined according to the actual situation. And because the two gears rotate synchronously, when rotating the same angle, the stroke passed by the first gear is greater than that of the second gear. Therefore, when the left door panel moves to the left, the first gear also moves to the left, but its rotation will drive the second rack to move to the right. The second rack drives the right door panel to move to the right through the second connecting plate, the corresponding moving sliding frame, and the corresponding first connecting plate, so that the left door panel and the right door panel can be opened simultaneously; when closing, by the same principle, the two doors can be closed simultaneously. Therefore, it is more convenient to use. And this opening and closing mechanism is a pure mechanical structure, non-electrically driven, so it is strong and durable, saves electric power resources, and is safe and reliable.

[0015] Further, a positioning frame is provided at the lower end of the opening. The left door panel and the right door panel are respectively slidably connected to the positioning frame. Such a setting facilitates the translational sliding of the two door panels driven by the opening and closing mechanism. Removable positioning insertion rods are symmetrically arranged in the middle of the positioning frame. The positioning insertion rods respectively penetrate through the positioning frame, the left door panel, the right door panel and are threadedly connected to the lower end of the device box. Such a setting facilitates the limiting of the left door panel and the right door panel and provides sealing protection for the opening.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. To solve the problems that the existing emergency power supply quick access device has poor protection performance, fixed position and inconvenient movement, which reduces the practicality of use. In this application, by using the device box, moving rollers, left door panel, right door panel, opening and closing mechanism, positioning frame and positioning insertion rods in combination, it is convenient to protect the device body and also convenient to move the whole. By using the support bottom plate, moving guide rail, fixed side plate and buffer connection components in combination, it is convenient to fix and limit the device body. At the same time, it is convenient to move the device body during use and also reduces the impact of vibration on the emergency power supply, improving the practicality of use.

[0018] 2. To solve the problems that when the existing emergency power supply quick access device is in use, the heat dissipation effect is poor, the internal equipment cannot be effectively cooled, and too much heat cannot be discharged in time, which will damage the internal equipment and affect the normal use of the emergency equipment. In this application, by using the first heat dissipation mesh plate, the second heat dissipation mesh plate, the heat dissipation mechanism and the ventilation mesh plate in combination, it is convenient to effectively cool the internal equipment and discharge the heat in time, avoiding damage to the emergency equipment caused by temperature reasons.

[0019] 3. By setting the opening and closing mechanism, the left door panel and the right door panel can be opened and closed simultaneously, which is convenient to use. Since the opening and closing mechanism adopts a pure mechanical structure design instead of the traditional electric control drive, such a setting makes the device reliable and durable, with low failure rate. At the same time, it is beneficial to reduce the manufacturing cost and also save energy consumption. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] According to Figure 1 , Figure 2 , Figure 3 and Figure 7As shown in the figure, moving rollers 2 are symmetrically arranged at the bottom of the lower end of the device box 1, and an opening 101 is formed in the middle of the front surface of the device box 1. At the same time, a left door panel 3 and a right door panel 4 are arranged on both sides of the front side of the opening 101. The upper ends of the left door panel 3 and the right door panel 4 are connected to the upper end of the front surface of the device box 1 through an opening and closing mechanism 5, and the lower ends of the left door panel 3 and the right door panel 4 are slidably connected to a positioning frame 6 arranged at the lower end of the front surface of the device box 1.

A storage cavity 104 is arranged below the support bottom plate 102 at the lower end inside the device box 1, which is convenient for storing objects and making reasonable use of the internal space of the device box 1. A sealing door 105 is installed on one side of the storage cavity 104 through a hinge. At the same time, a ventilation net plate 106 is arranged above the sealing door 105 on one side of the device box 1.

[0043] Specifically, the opening and closing mechanism 5 includes a horizontal seat 501. Two moving sliding frames 502 are symmetrically and slidably connected to the outer side of the front surface of the horizontal seat 501. The lower ends of the two moving sliding frames 502 are connected to the upper ends of both sides of the left door panel 3 and the right door panel 4 through first connecting plates 503. At the same time, a mounting bracket 504 is installed on one side of the moving sliding frame 502 arranged above the left door panel 3. A first gear 505 and a second gear 506 are installed on the mounting bracket 504. The upper end of the second gear 506 is engaged with a first rack 507. At the same time, the first rack 507 is installed at the upper end of the front surface of the device box 1. The upper end of the first gear 505 is engaged with a second rack 508. The lower end of the other side of the second rack 508 is slidably connected to a chute opened in the inner side of the upper end of the first rack 507 through a slider 509. At the same time, the lower end of one side of the second rack 508 is connected to one side of the moving sliding frame 502 arranged above the right door panel 4 through a second connecting plate 510.

[0044] Further explanation, the first gear 505 is located outside the second gear 506, and the size of the first gear 505 is larger than that of the second gear 506. The specific size difference is determined according to the actual situation. At the same time, the first gear 505 and the second gear 506 are rotatably arranged synchronously on the mounting bracket 504.

[0045] According to Figure 2 and Figure 6As shown in the figure, a fixed side plate 9 is arranged inside the device box 1 at the rear side of the device body 8. A plurality of magnetic blocks 802 arranged at equal intervals on the rear side of the device housing 801 are magnetically connected to the fixed side plate 9. And the fixed side plate 9 is connected to the inner wall of the device box 1 through a plurality of buffer connection components 10. The buffer connection components 10 include sleeves, fixed insertion rods and buffer springs. The fixed insertion rods are slidably connected inside the sleeves. And the other ends of the fixed insertion rods penetrate through the sleeves and are connected to the inside of the device box 1. At the same time, buffer springs are sleeved outside the fixed insertion rods between the device box 1 and the sleeves, which is convenient for blocking and supporting the rear side of the device body 8 and improving the stability of placement. A heat dissipation mechanism 11 is installed in the middle of the upper end inside the device box 1, and the heat dissipation mechanism 11 is located above the device body 8.

[0046] Specifically, the heat dissipation mechanism 11 includes a first driving motor 1101. An installation seat 1102 is installed on the top of the first driving motor 1101, and the installation seat 1102 is connected to the top end inside the device box 1 through fixing screws. At the same time, limiting frames 1103 are symmetrically arranged on both sides of the first driving motor 1101. An installation frame 1104 is arranged between the lower ends of the two limiting frames 1103. And the middle parts on both sides of the installation frame 1104 are rotatably connected to the lower ends of the corresponding limiting frames 1103 through connecting bumps 1105. At the same time, the middle part inside the installation frame 1104 is movably connected to a second driving motor 1106 through a connecting piece 1107. The connecting piece 1107 can be a fixed spring, a universal connector on the existing market or other universal connection components, as long as it can make the second driving motor 1106 rotate freely. A connecting column 1108 arranged in the middle of the upper end of the second driving motor 1106 is connected to the lower side of one end of a rotating connecting piece 1109. And the upper end of the other end of the rotating connecting piece 1109 is connected to the output end of the first driving motor 1101. At the same time, a fan blade 1110 is threadedly connected to the output end of the second driving motor 1106.

[0047] In use, by separating the positioning plug rod 7 from the device box 1, the left door panel 3, the right door panel 4 and the positioning frame 6, and then pushing the left door panel 3, the moving sliding frame 502 connected to the upper end of the left door panel 3 drives the second gear 506 to move by engaging with the lower end of the first rack 507. At the same time, the first gear 505 rotates to drive the second rack 508 to move on the upper end of the first rack 507. Since the diameter of the first gear 505 is larger than that of the second gear 506, when the first gear 505 moves to the left, its rotation can drive the second rack 508 to move to the right. The second rack 508 drives the right door panel 4 to move to the right through the second connecting plate 510, the corresponding moving sliding frame 502 and the corresponding first connecting plate 503, so as to separate the left door panel 3 and the right door panel 4 to both sides at the same time, exposing the opening 101. Then, the connecting chuck 811 placed on the extension seat 8081 is removed, and the connecting wire 809 is extended to connect the connecting chuck 811 with the power supply line in the substation. Then, the device body 8 is started for emergency power supply through the control panel 806. During power supply, heat is generated. By starting the first driving motor 1101 and the second driving motor 1106, the second driving motor 1106 drives the fan blade 1110 to rotate, generating an air flow to dissipate the heat through the first heat dissipation mesh plate 8012, the second heat dissipation mesh plate 8013 and the ventilation mesh plate 106. And the first driving motor 1101 drives the rotating connecting piece 1109 to rotate, so that the second driving motor 1106 rotates inside the mounting frame 1104 driven by the connecting column 1108, thereby changing the position of the fan blade 1110 to dissipate heat at different positions and improving the practicality of use.

[0048] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
