Description

Technical Field

[0001] This utility model relates to the field of fire protection technology, specifically to an online fire-fighting EPS emergency power supply. Background Technology

[0002] With the rapid development of intelligent and large-scale modern buildings, fire safety has become increasingly crucial in the public safety system. Various high-rise buildings, commercial complexes, hospitals, data centers, and other locations place extremely high demands on the reliability of their power supply. In the event of emergencies such as fires or power outages, the stability and continuity of the emergency power supply system directly impacts core safety aspects such as personnel evacuation, the operation of fire-fighting equipment, and the protection of critical data.

[0003] Existing online fire-fighting EPS emergency power supplies generally lack dedicated cable management structures in their design. With the increasing complexity and integration of equipment functions, the number and types of cables also increase. Without effective cable management measures, numerous cables extend naturally and are randomly arranged inside or outside the equipment, easily becoming tangled together. When a cable fails and needs replacement, the knotted cables pull on each other, making it difficult for workers to accurately locate the faulty cable or easily remove it from the tangled bundle. Forced pulling may not only further damage the faulty cable but also affect other normal cables nearby, causing insulation wear, loose connections, and other potential malfunctions. Therefore, those skilled in the art provide an online fire-fighting EPS emergency power supply to solve the problems mentioned in the background. Utility Model Content

[0004] The purpose of this invention is to provide an online fire-fighting EPS emergency power supply to solve the problems in the existing technology.

[0005] This utility model provides the following technical solution: an online fire-fighting EPS emergency power supply, including a chassis, in which a power supply is installed by bolts, and three sets of inlets are equally spaced at the front end of the power supply. A cable management assembly for separately storing cables is provided on the front end surface of the power supply above the three sets of inlets, and baffle assemblies are provided on both sides of the chassis.

[0006] As a preferred embodiment of the above technical solution, the cable management assembly includes a fixed base fixedly mounted on the front surface of the power supply. A winding roller is rotatably connected inside the fixed base. Four sets of cable storage grooves are evenly spaced on the surface of the winding roller. Limiting grooves are provided between the four sets of cable storage grooves and the winding roller. A rotating disk is fixedly connected to the outer wall of the left end of the winding roller. A rotating rod is fixedly connected to the outer wall of the rotating disk on the side opposite to the fixed base. A spring groove is provided on the front surface of the fixed base to the left of the limiting groove. A spring is fixedly connected to the inner wall of the spring groove. A sliding rod is fixedly connected to the other end of the spring, and the sliding rod slides linearly within the spring groove. A positioning post is fixedly connected to the outer wall of the left side of the sliding rod. Several sets of positioning grooves are evenly spaced on the outer wall of the rotating disk corresponding to the rear surface of the positioning post.

[0007] As a preferred embodiment of the above technical solution, the portion of the positioning post inserted into the positioning groove is spherically designed, the inner surface of the positioning groove is a spherical surface adapted to the positioning post, and twelve sets of positioning grooves are equally spaced.

[0008] As a preferred embodiment of the above technical solution, the rotating rod is cylindrical in shape, and the outer wall of the rotating rod is ground.

[0009] As a preferred embodiment of the above technical solution, the baffle assembly includes two sets of through holes symmetrically opened on the outer walls of both sides of the chassis. A movable compartment is fixedly connected to the top surface of the chassis. A gear is rotatably connected inside the movable compartment. Two sets of sliding grooves are symmetrically opened on the inner walls of the movable compartment corresponding to the front and rear ends of the gear. A rack is slidably connected in each of the two sets of sliding grooves. One end of each rack meshes with the gear. A cover plate is fixedly connected to the bottom surface of each rack, and the cover plate is slidably connected to the through hole. A transmission disc is fixedly connected to the top surface of the gear, and the transmission disc is rotatably connected to the movable compartment. A threaded rod is threadedly connected to the transmission disc. Eight sets of threaded grooves are evenly spaced on the outer wall of the movable compartment corresponding to the bottom surface of the threaded rod.

[0010] As a preferred embodiment of the above technical solution, the outer wall of the two sets of cover plates facing the through hole is glued with a sealing ring, and the other side of the sealing ring is tightly fitted to the inner wall of the through hole.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention involves passing one end of multiple cables through corresponding limiting slots and winding them once around a cable storage trough. A rotating rod then drives a winding roller within a fixed base via a rotating disc, causing the cable storage trough to rotate and wind the cables. Simultaneously, the rotating disc rotates, causing a positioning pin to slide a sliding rod on a spring groove, stretching the spring until the cables are fully wound. At this point, the spring's restoring force causes the sliding rod to return to its original position within the spring groove, and the positioning pin inserts into the positioning groove. This achieves the purpose of limiting the rotation of the rotating disc, enabling individual storage and management of multiple cables on the chassis. This prevents multiple cables from tangling, which would increase the difficulty of cable replacement and consequently affect power supply.

[0013] This invention utilizes a threaded rod that rotates within a transmission disc, causing the threaded rod to exit the threaded groove. The transmission disc then drives a gear to rotate within a movable chamber, which in turn drives two sets of racks to slide in opposite directions within a sliding groove. This causes two sets of cover plates to slide out through a through hole, facilitating maintenance of the power supply within the chassis and reducing the difficulty of power supply repair. It also makes it easier for staff to replace the cover plates. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Please see Figures 1-5 As shown, this utility model provides a technical solution: an online fire-fighting EPS emergency power supply, including a chassis 1, a power supply 2 installed in the chassis 1 by bolts, three sets of inlet ports 3 are equally spaced at the front end of the power supply 2, a cable management assembly 4 for separately storing cables is provided on the front surface of the power supply 2 above the three sets of inlet ports 3, and baffle assemblies 5 are provided on both sides of the chassis 1.

[0022] As one implementation method in this embodiment, please refer to Figure 1 and Figure 2 as well as Figure 5 As shown, the cable management assembly 4 includes a fixed base 41 fixedly mounted on the front surface of the power supply 2. A winding roller 42 is rotatably connected inside the fixed base 41. Four sets of cable storage grooves 43 are evenly spaced on the surface of the winding roller 42. Limiting grooves 44 are provided between the four sets of cable storage grooves 43 and the winding roller 42. A rotating disk 45 is fixedly connected to the outer wall of the left end of the winding roller 42. A rotating rod 46 is fixedly connected to the outer wall of the rotating disk 45 on the side opposite to the fixed base 41. A spring groove 47 is provided on the front surface of the fixed base 41 to the left of the limiting groove 44. A spring 48 is fixedly connected to the inner wall of the spring groove 47. A sliding rod 49 is fixedly connected to the other end of the spring 48, and the sliding rod 49 slides linearly in the spring groove 47. A positioning post 410 is fixedly connected to the outer wall of the left side of the sliding rod 49. Several sets of positioning grooves 411 are evenly spaced on the outer wall of the rotating disk 45 corresponding to the rear end surface of the positioning post 410.

[0023] Specifically, multiple cables are wound around the cable storage trough 43 by passing one end of each cable through the corresponding limiting groove 44. Then, the rotating rod 46 drives the winding roller 42 to rotate within the fixed base 41 via the rotating disk 45, causing the cable storage trough 43 to rotate and wind the cables. As the rotating disk 45 rotates, the positioning post 410 drives the sliding rod 49 to slide on the spring groove 47 and stretches the spring 48 until the cables are wound up. At this time, the restoring force of the spring 48 will drive the sliding rod 49 to return to its original position within the spring groove 47, and the positioning post 410 will insert into the positioning groove 411, thereby achieving the purpose of limiting the rotation of the rotating disk 45. This allows for the separate storage and management of multiple cables on the chassis 1, preventing multiple cables from getting tangled, which would increase the difficulty for staff to replace cables and thus affect the power supply of the power supply 2.

[0024] As one implementation method in this embodiment, please refer to Figures 1-5 As shown, the part of the positioning post 410 that is inserted into the positioning groove 411 is designed with a spherical surface. The inner surface of the positioning groove 411 is a spherical surface that is adapted to the positioning post 410. The positioning groove 411 is provided with twelve sets of equal spacing.

[0025] In practice, this allows workers to easily rotate the rotating disk 45 using the rotating rod 46, causing the positioning groove 411 on the rotating disk 45 to continuously press against the positioning post 410. This causes the positioning post 410 to slide along the inner wall of the positioning groove 411, driving the sliding rod 49 to slide within the spring groove 47, and allowing the positioning post 410 to slide out of the positioning groove 411. This achieves the purpose of quickly releasing the limiting position of the rotating disk 45, enabling the cable storage trough 43 to wind up the cable.

[0026] As one implementation method in this embodiment, please refer to Figures 1-5 As shown, the rotating rod 46 has a cylindrical design, and the outer wall of the rotating rod 46 has been ground.

[0027] In practice, this increases the contact area and friction between the operator and the rotating rod 46, thereby ensuring the stability of the rotating rod 46 during use. It also makes it easier and faster to rotate the rotating disk 45 by the rotating rod 46.

[0028] As one implementation method in this embodiment, please refer to Figure 1 and Figure 3 as well as Figure 5 As shown, the baffle assembly 5 includes two sets of through holes 51 symmetrically opened on the outer walls of both sides of the chassis 1. A movable chamber 52 is fixedly connected to the top surface of the chassis 1. A gear 53 is rotatably connected inside the movable chamber 52. Two sets of sliding grooves 54 are symmetrically opened on the inner walls of the movable chamber 52 corresponding to the front and rear ends of the gear 53. A rack 55 is slidably connected in both sets of sliding grooves 54. One end of each rack 55 meshes with the gear 53. A cover plate 56 is fixedly connected to the bottom surface of each rack 55, and the cover plate 56 is slidably connected to the through hole 51. A transmission disc 57 is fixedly connected to the top surface of the gear 53, and the transmission disc 57 is rotatably connected to the movable chamber 52. A threaded rod 58 is threadedly connected inside the transmission disc 57. Eight sets of threaded grooves 59 are equally spaced on the outer wall of the movable chamber 52 corresponding to the bottom surface of the threaded rod 58.

[0029] Specifically, the threaded rod 58 rotates within the transmission disc 57, causing it to exit the threaded groove 59. The transmission disc 57 then drives the gear 53 to rotate within the movable chamber 52, which in turn drives two sets of racks 55 to slide in opposite directions within the sliding groove 54. This causes two sets of cover plates 56 to slide out of the through hole 51, facilitating maintenance of the power supply 2 within the chassis 1 and reducing the difficulty of maintenance. It also facilitates the replacement of the cover plates 56.

[0030] As one implementation method in this embodiment, please refer to Figures 1-3As shown, sealing rings are glued to the outer wall of the two sets of cover plates 56 facing the through hole 51, and the other side of the sealing rings is tightly attached to the inner wall of the through hole 51.

[0031] Specifically, this can increase the sealing between the cover plate 56 and the through hole 51, preventing dust or insects from entering the power supply 2 through the through hole 51 and interfering with the power supply 2.

[0032] Working principle: First, one end of multiple cables is passed through the corresponding limit grooves 44 and wound around the cable storage groove 43 once. Then, the rotating rod 46 drives the winding roller 42 to rotate in the fixed seat 41 through the rotating disk 45, and the cable storage groove 43 rotates and winds the cables. At the same time as the rotating disk 45 rotates, the positioning post 410 drives the slide rod 49 to slide on the spring groove 47 and stretches the spring 48 until the cable is wound up. At this time, the restoring force of the spring 48 will drive the slide rod 49 to return to its original position in the spring groove 47 and the positioning post 410 will be inserted into the positioning groove 411, thereby achieving the purpose of winding and organizing multiple cables at the docking entrance 3.

[0033] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
