Description

Technical Field

[0001] The present invention relates to the technical field of rolling shutter controllers.

[0002] In particular, the present invention relates to a fireproof roller shutter controller which is easy to maintain. Background Art

[0003] Fireproof rolling shutter is a fire protection product that can timely cut off the fire source and effectively control the spread of fire when a fire occurs. It is widely used in fire isolation of large-scale buildings such as large shopping malls, supermarkets, exhibition centers, airports, and rail transit stations. In order to automatically control the fireproof rolling shutter motor to lower the fireproof rolling shutter to cut off the fire source when the main power (380V) is cut off when a fire occurs, a fireproof rolling shutter controller with power distribution function must be used.

[0004] However, in the event of a fire, the control box cannot effectively protect the internal components. Once the internal components are damaged, the fireproof roller shutter controller may not work properly, and it cannot automatically control the fireproof roller shutter motor to lower the fireproof roller shutter to cut off the fire source. Therefore, most of the roller shutter controllers are now designed to set the control box as a fireproof box, and weld or fix the various components of the controller in the control box. For example, the Chinese patent utility model patent CN207553941U relates to a fireproof roller shutter controller assembly and a fireproof roller shutter controller. The above utility model discloses a fireproof roller shutter controller assembly, which includes a first box, a second box, a first protective cover and a second protective cover. A accommodating chamber and a first opening connecting the accommodating chamber with the outside are provided in the first box; the first protective cover is connected to the first box, and the first protective cover is used to close or open the first opening. The second box is arranged in the accommodating chamber, and the second box includes a protective chamber and a second opening connecting the protective chamber with the outside; the second protective cover is connected to the second box, and is used to close or open the second opening. The protective chamber is used to install the controller. The fireproof roller shutter control structure is simple in structure and easy to use, and is used to protect the fireproof roller shutter controller, so as to ensure that the fireproof roller shutter controller can work normally in case of fire, thereby reducing the number of casualties and property losses.

[0005] However, the above-mentioned fireproof roller shutter control structure still has the following problems: the control box has a simple structure, and the components installed inside it are directly installed on the inner wall of the box, the layout is messy, and it is difficult to test once connected. The wiring between the components is leaked on the side of the component away from the inner wall of the box. It is not convenient to disassemble the components when they are damaged, which is not convenient for subsequent maintenance.

[0006] Therefore, in order to solve the above problems, it is necessary for us to design a reasonable, efficient and easy-to-maintain fire shutter controller. Summary of the invention

[0007] The purpose of the present invention is to provide a fire shutter controller which is simple in structure, with each component installed on a mounting frame. The bottom of each component is hollowed out when it is installed, which is convenient for factory testing. After the test is completed, the mounting frame is installed in a placement box, and the wiring between the components is also hidden in the mounting frame. It is not only aesthetically pleasing but also has high wiring concealment security. Each component is installed separately and can be disassembled and repaired separately, which reduces the cost of maintenance and replacement and is easy to maintain.

[0032] Embodiment 1: Figures 1 to 4 The figure shows only one embodiment of the present invention, a fireproof roller shutter controller which is easy to maintain, comprising a mounting frame 5 for mounting a main board 1, a three-phase electric board 2, a power supply component 3 and a feedback component 4, and a placement box 6 for placing the mounting frame 5, the bottom of the mounting frame 5 is provided with a fixing foot 55 and a fixing bolt 56 for passing through the fixing foot 55 and inserted into the bottom plate of the placement box 6, the mounting frame 5 is provided with a first mounting frame 51 for mounting the main board 1, a second mounting frame 52 for mounting the three-phase electric board 2, a third mounting frame 53 for mounting the power supply component 3 and a fourth mounting frame 54 for mounting the feedback component 4, the first mounting frame 51, the second mounting frame 52, the third mounting frame 53 and the fourth mounting frame 54 are all hollowed out on one side of the bottom plate of the placement box 6, and the main board 1, the three-phase electric board 2, the power supply component 3 and the feedback component 4 are all provided with wiring terminals.

[0033] In the present invention, the placement box 6 serves as an outer shell, and a mounting frame 5 on which four components, namely, a main board 1, a three-phase power board 2, a power supply assembly 3 and a feedback assembly 4, are installed is placed inside the placement box 6. Here, the main board 1 is a main circuit board used for data transmission and processing. The main board 1 can issue instructions to control the lifting, lowering, emergency stop, self-test and lifting speed of the rolling shutter door. The three-phase power board 2 is a three-phase (live wire, neutral wire and ground wire) external power supply AC380V or AC220V. The three-phase power board 2 is provided with high-voltage electrical components such as a main power socket and a transformer. The city power is converted into 12V direct current through a transformer to power the main board 1; the power supply assembly 3 is a low-voltage power supply, generally a DC3.7V lithium battery. The power supply assembly 3 is provided with an inverter and a relay for inverting DC3.7V into DC12V to power the main board 1; the feedback assembly 4 is a control assembly. The user can send a control instruction to the main board 1 through a remote button or a control button connected to the feedback assembly 4, and the main board 1 converts the control instruction into a control signal and sends it to the rolling shutter door motor.

[0034] It should be noted that, for ease of understanding, the direction of the bottom plate of the placement box 6 is referred to as the "lower side", and the direction of the cover plate of the placement box 6 is referred to as the "upper side" below.

[0035] First, the structure of the mounting frame 5, on which is provided a first mounting frame 51 for mounting the mainboard 1, a second mounting frame 52 for mounting the three-phase power board 2, a third mounting frame 53 for mounting the power supply component 3, and a fourth mounting frame 54 for mounting the feedback component 4, for separating and placing the four components separately. Of course, the sizes of the four mounting frames need to be preset in advance so as to be able to place just four components.

[0036] Then there is the structure of four mounting frames, wherein the first mounting frame 51, the second mounting frame 52, the third mounting frame 53 and the fourth mounting frame 54 are all hollowed out on one side of the bottom plate of the placement box 6, and the main board 1, the three-phase power board 2, the power supply component 3 and the feedback component 4 are all provided with wiring terminals, and the mounting frame 5 has a certain height, and the four mounting frames are all arranged on the upper side of the mounting frame 5, so the lower sides of the four components installed on the four mounting frames are all at a certain distance from the bottom plate of the placement box 6, and the connecting wires connected to the wiring terminals of the four components are all arranged on the lower side of the mounting frame 5 to avoid exposed wiring.

[0037] Then, the components are installed. A first buckle 511 is provided on one side of the first installation frame 51. A second buckle 512 is provided on one side of the first installation frame 51 away from the first buckle 511. The side of the second buckle 512 away from the bottom plate of the placement box 6 is arc-shaped. Moreover, the first installation frame 51 is provided with a mounting hole 513. The main board 1 is provided with a main board hole 11 and a connecting bolt for passing through the main board hole 11 and inserting into the mounting hole 513. When installing the main board 1, firstly, one side of the main board 1 is inserted between the first buckle 511 and the first installation frame 51. Then, the side of the main board 1 close to the second buckle 512 is pressed down, and the arc of the upper side of the second buckle 512 is inserted between the lower side of the second buckle 512 and the first installation frame 51. Finally, the connecting bolt is inserted through the main board hole 11 into the mounting hole 513 to complete the fixing of the main board 1.

[0038] Of course, the three-phase power board 2 is installed on the second installation frame 52 and the feedback component 4 is installed on the fourth installation frame 54 in the same way.

[0039] Only the installation method of the power supply assembly 3 is different. The power supply assembly 3 includes a power supply frame 31 and a power supply 32 arranged in the power supply frame 31. The depth of the power supply frame 31 is not less than the depth of the third installation frame 53. It is equivalent to that the lower side of the power supply frame 31 is lower than the lower side of the third installation frame 53, and the upper edge of the power supply frame 31 is inserted into the third installation frame 53. The power supply 32 is actually a DC3.7V lithium battery, and the battery is sealed at the bottom of the power supply frame 31 by glue filling, which can prevent the battery from being exposed and extend the battery life.

[0040] An elastic buckle 33 is provided at the edge of the power frame 31, and a limiting plate 34 is provided at the edge of the power frame away from the elastic buckle 33. A limiting hole 35 is provided on the limiting plate 34. When the power frame 31 is installed, it is inserted downward from the third mounting frame 53 until the bottom side of the limiting plate 34 contacts the upper side of one side of the third mounting frame 53. At this time, the elastic buckle 33 elastically presses against the inner side of the other side of the third mounting frame 53, and then the limiting bolt passes through the limiting hole 35 and is screwed into the limiting mounting hole on the third mounting frame 53 to complete the fixation of the power frame 31.

[0041] Finally, the mounting frame 5 is fixed. The bottom of the mounting frame 5 is provided with a fixing foot 55 and a fixing bolt 56 that is inserted through the fixing foot 55 and into the bottom plate of the placement box 6 .

[0042] The present invention modularly installs the main board 1, the three-phase electric board 2 in the high-voltage area, the power supply component 3 in the low-voltage area, and the feedback component 4 in the human-computer interaction area on the mounting frame 5. At this time, the four component modules can be directly factory tested from the bottom side of the mounting frame 5. After the test is passed, the bottom side of the mounting frame 5 is fixedly installed to the bottom plate of the placement box 6. During use, if any module is damaged, it can be repaired or replaced separately without replacing all parts together, thereby reducing the cost of repair and replacement.

[0043] The fireproof roller shutter controller which is easy to maintain of the present invention has a simple structure. Each component is installed on a mounting frame. The bottom of each component is hollowed out when it is installed, which is convenient for factory testing. After the test is completed, the mounting frame is installed in a placement box. The wiring between the components is also hidden in the mounting frame, which not only has good aesthetics but also has high wiring concealment safety. Each component is installed separately and can be disassembled and repaired separately, which reduces the cost of maintenance and replacement.

[0044] Embodiment 2, still as Figures 1 to 4 The figure shown is only one of the embodiments of the present invention. On the basis of the first embodiment, in a fireproof roller shutter controller that is easy to maintain of the present invention, the first mounting frame 51, the second mounting frame 52, the third mounting frame 53 and the fourth mounting frame 54 are located on the same horizontal plane away from the side of the bottom plate of the placement box 6, so that the upper sides of the main board 1, the three-phase power board 2, the power supply component 3 and the feedback component 4 are located on the same level after installation.

[0045] Of course, a reinforcing transverse plate 514 is disposed in the middle of the first installation frame 51 . Generally, the mainboard 1 has a larger area, and the area of ​​the first installation frame 51 is also larger. In order to support the mainboard 1 , a reinforcing transverse plate 514 is disposed in the middle of the first installation frame 51 .

[0046] In addition, triangular plates are provided at the corners of the first mounting frame 51 and the second mounting frame 52 and at the connection between the reinforcing cross plate 514 and the first mounting frame 51, which not only play the role of strengthening the structure, but also limit the main board 1 and the three-phase power board 2 to limit their bottom height.

[0047] In addition, the mounting frame 5 is a plastic part, which is light in weight, low in design cost, and convenient for slotting.

[0048] Furthermore, the placement box 6 is a metal piece, which plays a role in protecting the mounting frame 5 and various components in the placement box 6.

[0049] Then, a bolt barrel is arranged on the bottom plate of the placement box 6 for facilitating the insertion of the fixing bolt 56, and an internal thread is arranged inside the bolt barrel for cooperating with the external thread of the fixing bolt 56, and a box cover plate 61 is arranged on the side of the placement box 6 away from the bottom plate.

[0050] Of course, the number of the bolt barrel and the number of the fixing foot 55 are at least one.

[0051] Finally, a wiring buckle 521 for clamping the connecting wires is provided on one side of the outer side of the mounting frame 5 close to the second mounting frame 52, which is used to clamp the three-phase wires and other connecting wires leading to the three-phase power board 2 to prevent accidental touch.
