Description

Technical Field

[0001] The present invention relates to the technical field of emergency power supply, and more particularly to a zero-switching emergency power supply device without a phase-locked loop. Background Art

[0002] Emergency power supply is an emergency power supply used in important buildings today for emergency lighting, accident lighting, and fire-fighting facilities. It is mainly composed of a shell, input unit, output unit, charging module, battery pack, inverter, monitor, output switching device, etc. The system can provide emergency power supply in an emergency state.

[0003] The existing emergency power supply needs to open the cover when repairing or replacing the power supply. The cover is generally fixed directly to the shell by bolts, and the bolts need to be loosened one by one to open it, which is slow. Another method is to open the door with one side hinged and fixed and the other side lifted up. It takes up a lot of space when opened and is prone to collision. Summary of the invention

[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides a zero-switching emergency power supply device without a phase-locked loop. The technical problem to be solved by the present invention is that the cover plate is generally fixed directly to the shell by bolts, and the bolts need to be loosened one by one to open it, which is slow. Another method is to open the door with one side hinged and fixed and the other side lifted up, which occupies a large space when opened.

[0005] To achieve the above object, the present invention provides the following technical solution: a zero-switching emergency power supply device without a phase-locked loop, comprising a power supply body, and a cavity opened on one side of the power supply body, wherein a cover mechanism is provided in the cavity;

[0006] The cover mechanism includes a flexible layer connected to the top of the cavity, rods arranged along the length direction of the power source body are arranged at intervals on the top of the flexible layer, a slot is provided above the cavity, and three fixing mechanisms in contact with the side edges of the flexible layer are provided inside the cavity; the fixing mechanism includes a fixing bar, a slide groove for accommodating the reciprocating sliding of the fixing bar is provided in the power source body, a sealing layer is provided on the side of the fixing bar facing the flexible layer, a rotating shaft is provided on the side of the fixing bar away from the sealing layer, a connecting rod is provided between the rotating shaft and the fixing bar, a movable block is provided at the bottom of the rotating shaft, a movable groove is penetrated through the movable block, and a driving mechanism is provided in the movable groove.

[0007] The specific implementation method is as follows: when the protective mechanism is opened, the staff can start to wind the flexible layer from the bottom end. The wound flexible layer occupies a small area and will not collide with the outside world during the opening process. The staff can place the wound flexible layer in the slot for storage to avoid damage by tools during maintenance of the power supply body, and under the constraint of the slot, the wound flexible layer itself will not unfold, freeing the hands of the staff and improving the maintenance efficiency. The rods distributed at intervals on the flexible layer strengthen the strength of the entire flexible layer, so that the flexible layer will transmit force to the rods in the force-bearing area under the action of external force, thereby ensuring the safety of the internal components of the power supply body. When the protective mechanism is closed, the wound flexible layer can be quickly unfolded and laid in the cavity, and the driving mechanism can push the movable block to slide toward the flexible layer. The movable block will drive the top shaft to move synchronously, and the shaft pushes the sealing layer on the fixed bar through the connecting rod to contact the flexible layer to achieve sealing, which has dustproof and waterproof effects, and no bolts are required for installation and disassembly.

[0008] Furthermore, the driving mechanism includes a driving rod, a driving wheel is fixedly arranged on the outside of the driving rod, and a driving groove meshing with the driving wheel is arranged on one side of the movable groove. The driving rod drives the fixedly connected driving wheel to rotate, and the driving wheel drives the movable block to move through the meshing driving groove.

[0009] Furthermore, the power source body is provided with a groove at a position corresponding to the driving rod, and the end of the driving rod away from the driving wheel passes through the power source body and is located in the groove, and a turning handle fixedly connected to the driving rod is provided in the groove. The driving rod is located in the groove so that the driving rod does not protrude from the surface of the power source body, thereby improving the aesthetics.

[0010] Furthermore, the driving rod is provided with a self-locking mechanism; the self-locking mechanism includes a ratchet and a ratchet rod, the ratchet is fixedly connected to the driving rod, one end of the ratchet rod is in contact with the ratchet, the end of the ratchet rod away from the ratchet is rotatably connected to the power source body through a rotating rod, a torsion spring is sleeved on the surface of the rotating rod, one end of the torsion spring is fixedly connected to the ratchet rod, and the other end is fixedly connected to the power source body, and the ratchet rod is made of metal material. The torsion spring connected to the ratchet rod applies a torsion force to the ratchet rod, pushing the ratchet rod to contact the ratchet, so that the ratchet can only rotate in one direction.

[0011] Furthermore, the flexible layer is made of elastic rubber material, the rod body is fixedly connected to the flexible layer, the rod body is made of metal or hard plastic material, a baffle is provided above the slot, and the baffle is connected to the power source body through a damping hinge. The rod body is fixedly connected to the flexible layer to improve the overall strength, and the rod body is made of metal or hard plastic material, has strong bearing capacity and is not easy to be damaged.

[0012] Furthermore, a sealing opening is provided on one side of the sealing layer facing the flexible layer, and the cross-sectional shape above the sealing opening is set to be an arc shape. The sealing opening allows the sealing layer and the flexible layer to fit more deeply.

[0013] Furthermore, the connecting rods are provided in two numbers, one end of the two connecting rods is rotatably connected to the rotating shaft, and the other end is rotatably connected to the fixing bar. The two connecting rods and the fixing bar form a triangle, so that when the connecting rods push the fixing bar, the fixing bar has high movement stability.

[0014] Furthermore, the power source body is provided with an annular cover that fits with the groove, a sealing ring is fixedly provided on the surface of the annular cover opposite to the groove, a control rod is fixedly provided on the annular cover, the control rod penetrates the power source body and is rotatably connected with the power source body, an adsorbent is fixedly provided on the outer side of the control rod, and the adsorbent is configured as a magnet. When the annular cover fits with the groove, the sealing ring is squeezed to achieve sealing, thereby preventing external dust or rainwater from penetrating into the groove.

[0015] Furthermore, a limit block that abuts against the slide groove is fixed on the top of the fixed bar, a guide block is fixed on the top of the movable block, a guide groove for accommodating the sliding of the guide block is provided in the power source body, a protective layer is fixed between the adjacent rods, the protective layer is made of metal wire material, and a fire retardant coating is sprayed on the surface of the flexible layer. When the fixed bar slides toward the flexible layer, the limit block will abut against the slide groove, limit the sliding stroke of the fixed bar, and prevent the fixed bar from sliding out of the slide groove.

[0016] Technical effects and advantages of the present invention:

[0017] 1. The present invention is provided with a cover mechanism, so that the wound flexible layer occupies a small area and will not collide with the outside world during the opening process. Under the constraint of the slot, the wound flexible layer itself will not unfold, freeing the hands of the staff and improving the maintenance efficiency. The rods distributed at intervals on the flexible layer strengthen the strength of the entire flexible layer and ensure the safety of the internal components of the power supply body.

[0018] 2. The present invention provides a ratchet rod, and a torsion spring connected to the ratchet rod applies torque to the ratchet rod, which pushes the ratchet rod to contact the ratchet wheel, so that the ratchet wheel can only rotate in one direction but cannot reverse. Since the ratchet wheel is connected to the driving rod, the driving rod will not reverse, thereby achieving the purpose of self-locking, preventing the driving rod from loosening due to external vibration, and ensuring the sealing effect.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] The implementation method is specifically as follows: when the protective mechanism is opened, the staff can wind the flexible layer 3 from the bottom end. The wound flexible layer 3 occupies a small area and will not collide with the outside world during the opening process. The staff can place the wound flexible layer 3 in the slot 5 for storage to avoid being damaged by tools during maintenance of the power supply body 1, and under the constraint of the slot 5, the wound flexible layer 3 itself will not unfold, freeing the hands of the staff and improving the maintenance efficiency. The rods 4 distributed at intervals on the flexible layer 3 strengthen the strength of the entire flexible layer 3, so that the flexible layer 3 will transmit the force to the rods 4 in the force-bearing area under the action of external force, thereby ensuring the safety of the internal components of the power supply body 1. When the protective mechanism is closed, the wound flexible layer 3 can be quickly unfolded and laid in the cavity 2, and the driving mechanism can push the movable block 10 to slide toward the flexible layer 3, and the movable block 10 will drive the top shaft 8 to move synchronously. The shaft 8 pushes the sealing layer 7 on the fixed bar 6 to contact the flexible layer 3 through the connecting rod 9, which is convenient for disassembly and assembly.

[0031] like Figure 3-5 As shown, in this embodiment, the driving mechanism includes a driving rod 12, a driving wheel 13 is fixedly provided on the outer side of the driving rod 12, and a driving groove 14 meshing with the driving wheel 13 is provided on one side of the movable groove 11. The driving rod 12 drives the fixedly connected driving wheel 13 to rotate, and the driving wheel 13 drives the movable block 10 to move through the meshing driving groove 14. When the movable block 10 moves toward the fixed bar 6, the sealing layer 7 is pushed to fix the flexible layer 3. When the movable block 10 moves toward the driving rod 12, the sealing layer 7 is pulled to separate from the flexible layer 3.

[0032] like Figure 2 and Figure 5As shown, in this embodiment, the power source body 1 is provided with a groove at a position corresponding to the driving rod 12, and one end of the driving rod 12 away from the driving wheel 13 penetrates the power source body 1 and is located in the groove, and a rotating handle 15 fixedly connected to the driving rod 12 is provided in the groove. The driving rod 12 is located in the groove, so that the driving rod 12 does not protrude from the surface of the power source body 1, thereby improving the aesthetics. The driving rod 12 is connected to the rotating handle 15, and the rotating handle 15 can increase the friction with the hand, which is convenient for use.

The torsion spring 18 connected to the ratchet rod 17 applies a torsion force to the ratchet rod 17, pushing the ratchet rod 17 to contact the ratchet 16, so that the ratchet 16 can only rotate in one direction, but cannot reverse. Since the ratchet 16 is connected to the driving rod 12, the driving rod 12 will not reverse, so as to achieve the purpose of self-locking and ensure the sealing effect of the sealing layer 7.

[0034] like Figure 1 , Figure 2 and Figure 8 As shown, in this embodiment, the flexible layer 3 is made of elastic rubber material, the rod body 4 is fixedly connected to the flexible layer 3, the rod body 4 is made of metal or hard plastic material, a baffle 19 is provided above the slot 5, and the baffle 19 is connected to the power source body 1 through a damping hinge. The rod body 4 is fixedly connected to the flexible layer 3 to improve the overall strength. The rod body 4 is made of metal or hard plastic material, has strong bearing capacity and is not easy to be damaged. By flipping the baffle 19, the baffle 19 can cover the slot 5, further improving the storage stability of the flexible layer 3. The damping hinge will increase the rotation friction of the baffle 19 and play a positioning role.

[0035] like Figure 1 and Figure 4 As shown, in this embodiment, a sealing opening 20 is provided on the side of the sealing layer 7 facing the flexible layer 3, and the cross-sectional shape above the sealing opening 20 is set to be an arc shape. The sealing opening 20 allows the sealing layer 7 to fit more deeply with the flexible layer 3, and the arc-shaped sealing opening 20 allows the flexible layer 3 to slide into the sealing opening 20 more easily.

[0036] like Figure 3As shown, in this embodiment, the connecting rods 9 are provided in two numbers, one end of the two connecting rods 9 is rotatably connected to the rotating shaft 8, and the other end is rotatably connected to the fixing bar 6.

When the annular cover 21 is opened, the groove will be exposed, and the annular cover 21 will synchronously drive the control rod 22 to rotate. After the control rod 22 rotates, the adsorbent 23 will be exposed, and the adsorbent 23 will magnetically attract the ratchet rod 17, so that the ratchet rod 17 is separated from the ratchet wheel 16, so that the user can rotate the driving rod 12 conveniently.

When the fixed bar 6 slides toward the flexible layer 3, the limit block 24 will abut against the slide groove, limit the sliding stroke of the fixed bar 6, and prevent the fixed bar 6 from sliding out of the slide groove. The sliding direction of the movable block 10 can be guided by the guide block 25 to avoid problems such as deviation. The protective layer 26 made of metal wire material can enhance the anti-puncture effect of the flexible layer 3, and the sprayed fire-retardant coating can prevent the flexible layer 3 from burning, thereby improving the safety of use.
