Description

Technical Field

[0001] This invention relates to the field of fire alarm installation technology, and in particular to a portable fire alarm quick installation device. Background Technology

[0002] Fires almost simultaneously with the use of fire. With the continuous development of modern society and the increasing abundance of material resources, the stock of flammable and explosive materials has also increased, bringing both convenience and the risk of fire and explosion. Fire alarms are devices that detect factors such as large amounts of smoke and heat that could cause a fire and trigger an alarm. Installing fire alarms in spaces with fire hazards is an effective way to reduce the frequency of fires. However, in areas with densely packed pipelines transporting flammable and explosive gases, fire alarms are often installed very close to the edges. If a fire starts in the middle of the pipeline, by the time the alarm installed at the edge detects it, the fire has already intensified. Therefore, it is necessary to invent a mounting device for fixing fire alarms that can be installed on flat areas or on pipelines, and that can adjust the orientation of the fire alarm according to fire prevention needs, thereby ensuring that the fire alarm can detect fires more quickly.

[0044] Example:

[0045] This embodiment is used to assist in the installation of fire alarm 9.

[0046] like Figure 1-4 and Figure 6As shown, a portable fire alarm quick-installation device includes a support cylinder 1, a mounting frame 2, an orientation adjustment device 3, a telescopic device 4, a clamping device 5, a suction cup 6, a cleaning device 7, and a control terminal 8. The support cylinder 1 has a first mounting plate 101 and a second mounting plate 102 inside. The first mounting plate 101 is fixedly installed inside the support cylinder 1, and the second mounting plate 102 is located above the first mounting plate 101 and slidably installed inside the support cylinder 1. Figure 13 As shown, the mounting frame 2 is used to mount the fire alarm 9; the mounting frame 2 is connected to the top of the support cylinder 1 by four telescopic rods evenly distributed along the circumference of the bottom surface. One end of the telescopic rod is fixedly connected to the mounting frame 2, and the other end is ball-jointed to the top of the support cylinder 1; the orientation adjustment device 3 is installed between the mounting frame 2 and the second mounting plate 102, the telescopic device 4 is installed between the first mounting plate 101 and the second mounting plate 102, and the clamping device 5 is installed on the second mounting plate 102; four suction cups 6 are evenly distributed around the bottom of the support cylinder 1; the cleaning device 7 is set on the periphery of the support cylinder 1.

[0047] like Figure 6-8 As shown, the orientation adjustment device 3 includes a support frame 301, an adjusting gear 302, an adjusting electric push rod 303, an adjusting rack 304, a cross rod 305, a C-shaped rod 306, an adjusting gear 307, an adjusting electric push rod 308, and an adjusting rack 309; the support frame 301 is fixedly mounted on the mounting plate 102; the cross rod 305 has endpoints 1, 2, 3, and 4, with endpoints 1 and 3 facing each other, and endpoints 2 and 4 facing each other, and endpoints 1 and 3 are rotatably mounted on the support frame 301; the adjusting gear 302 is coaxially fixed... The adjustment electric push rod 303 is mounted on end point one and meshes with the adjustment rack 304; the adjustment electric push rod 303 is vertically fixedly mounted on the support frame 301, and its telescopic end is fixedly connected to the adjustment rack 304, which is vertically set; the two branch ends of the C-shaped rod 306 are rotatably connected to end point two and end point four respectively; the adjustment gear 307 is coaxially fixedly mounted on end point two and meshes with the adjustment rack 309; the adjustment electric push rod 308 is fixedly mounted on the C-shaped rod 306, and its telescopic end is fixedly connected to the adjustment rack 309; the C-shaped rod 306 is fixedly connected to the mounting frame 2.

[0048] Specifically, when adjusting the orientation of the mounting frame 2, the first adjusting electric push rod 303 is activated, which moves the first adjusting rack 304. The first adjusting rack 304 drives the first adjusting gear 302 to rotate, thereby causing the cross rod 305 to rotate around the straight rod where endpoints one and three are located, and the C-shaped rod 306 also moves accordingly. The second adjusting electric push rod 308 is activated, which moves the second adjusting rack 309. The second adjusting rack 309 rotates around the outer periphery of the second adjusting gear 307, thereby causing the C-shaped rod 306 to rotate around the straight rod where endpoints two and four are located. By adjusting the opening and closing of the first adjusting electric push rod 303 and the second adjusting electric push rod 308, the orientation of the mounting frame 2 is adjusted with the rotation of the C-shaped rod 306, thereby adjusting the orientation of the fire alarm 9.

[0049] like Figure 6 and Figure 9 As shown, the telescopic device 4 includes a drive motor 401, a bevel gear 402, a bevel gear 403, a transmission shaft 404, and a folding telescopic frame 405. Four folding telescopic frames 405 are provided, evenly distributed circumferentially between mounting plate 101 and mounting plate 202. Each folding telescopic frame 405 is vertically positioned, with its bottom fixedly mounted on mounting plate 101 and its top fixedly mounted on mounting plate 202. The folding telescopic frame 405 is a scissor-type telescopic frame, internally equipped with several internal gears and connecting rods. Each internal gear is connected to a connecting rod. The rods are fixedly connected; each folding telescopic frame 405 corresponds to a drive shaft 404, which is horizontally set and rotatably mounted on the second mounting plate 102. The outer end of the drive shaft 404 is coaxially and fixedly connected to the internal gear at the top of the corresponding folding telescopic frame 405, which is used to drive the folding telescopic frame 405 to extend and retract. The inner end is coaxially and fixedly connected to a second bevel gear 403; the first drive motor 401 is fixedly mounted on the second mounting plate 102, and its output end is coaxially and fixedly connected to the first bevel gear 402; the first bevel gear 402 meshes synchronously with all the second bevel gears 403;

[0050] Specifically, when adjusting the height of the mounting frame 2, the drive motor 401 is started, the bevel gear 402 rotates, and all the bevel gears 403 rotate synchronously. The bevel gears 403 drive the internal gears at the top of the corresponding folding telescopic frame 405 to rotate through the transmission shaft 404, so that all the folding telescopic frames 405 extend or retract synchronously, thereby driving the mounting plate 102 to move in the vertical direction to adjust the height of the mounting frame 2, and thus adjust the height of the fire alarm 9.

[0051] like Figure 5As shown, the clamping device 5 includes a bidirectional lead screw 501, a slider 502, a clamping electric push rod 503, a clamping motor 504, and a clamping rod 505. The bidirectional lead screw 501 is horizontally mounted on the bottom surface of the mounting plate 101, and two sliders 502 are symmetrically slidably mounted on the bidirectional lead screw 501. Each slider 502 is vertically fixedly mounted with a clamping electric push rod 503, and each clamping electric push rod 503 has a clamping rod 505 on its telescopic end, and each is fixedly mounted with a clamping motor 504. The clamping rod 505 is rotatably mounted on the telescopic end of the corresponding clamping electric push rod 503 through a horizontally set rotating shaft. The two clamping rods 505 are symmetrically arranged and work together for clamping. The output end of the clamping motor 504 is coaxially fixedly connected to the rotating shaft of the corresponding clamping rod 505.

[0052] Specifically, when the fire alarm 9 needs to be installed on the pipe, the two clamping electric push rods 503 are activated, the telescopic ends extend, and the clamping motor 504 and clamping rod 505 are driven to descend; the two clamping motors 504 are activated, and the two clamping rods 505 are driven to rotate, and the clamping rods 505 rotate to an angle that matches the pipe; when the pipe is between the two clamping rods 505, the bidirectional lead screw 501 is activated, the two sliders 502 move closer to each other, and drive the two clamping rods 505 to move closer to each other, thereby clamping the pipe; the clamping rods 505 can be selected according to the pipe diameter to match the appropriate type.

[0053] like Figure 10-12 As shown, the cleaning device 7 includes a rotating assembly 701, a lifting cylinder 702, an annular plate 703, a reciprocating lifting mechanism 704, a cleaning electric push rod 705, a cleaning brush 706, and a connecting frame 707. The annular plate 703 is arranged around the outside of the support cylinder 1. The rotating assembly 701 includes a second drive motor 7011, a rotating gear 7012, and an annular gear 7013. The annular gear 7013 is rotatably mounted on the support cylinder 1 and located below the annular plate 703. Two lifting cylinders 702 are provided, symmetrically and vertically fixedly mounted on the annular gear 7013, and their telescopic ends are fixedly connected to the annular plate 703. The second drive motor 7011 is fixedly mounted on the support cylinder 1, and its output end is fixedly connected to the rotating gear 7012. The rotating gear 7012 meshes with the annular gear 7013.

[0054] Two connecting frames 707 are symmetrically arranged on the annular plate 703. Each connecting frame 707 is equipped with a set of reciprocating lifting mechanisms 704. Each set of reciprocating lifting mechanisms 704 includes a drive motor 7041, a limiting roller 7042, a limiting slide rod 7043, and a sliding rod 7044. The drive motor 7041 is fixedly installed inside the bottom end of the connecting frame 707, and its output end is coaxially fixedly connected to the limiting roller 7042 through a transmission shaft. The limiting roller 7042 is rotatably mounted on the connecting frame 703. On the connecting frame 707; the limiting roller 7042 is provided with an elliptical groove, the limiting slide rod 7043 is slidably installed in the elliptical groove, the sliding rod 7044 is fixedly connected to the limiting slide rod 7043 and is vertically slidably installed on the connecting frame 707, and the cleaning electric push rod 705 is fixedly installed on the sliding rod 7044; the rotation of the limiting roller 7042 drives the limiting slide rod 7043 to slide in the elliptical groove, thereby driving the sliding rod 7044 to reciprocate up and down sliding on the connecting frame 707;

[0055] Two cleaning electric push rods 705 are fixedly installed on the inner side of each sliding rod 7044. Each cleaning electric push rod 705 is arranged horizontally along the radial direction of the annular plate 703 and points to the center of the annular plate 703. The telescopic end of the cleaning electric push rod 705 is fixedly connected to the cleaning brush 706.

[0056] Specifically, when the mesh of the fire alarm 9 is covered with dust and needs to be cleaned, firstly, the orientation adjustment device 3 is activated to restore the mounting frame 2 to a vertical orientation; then, the lifting cylinder 702 is activated, causing the annular plate 703 to rise, and the connecting frame 707 to move to the outside of the mesh of the fire alarm 9; finally, the cleaning electric push rod 705 is activated, causing the cleaning brush 706 to move towards the mesh; then, the drive motor 7041 is activated, the limiting roller 7042 rotates, and the limiting slide rod 7043 slides in the elliptical slide groove, causing the slide rod 7044 to perform reciprocating lifting and lowering motion, thereby driving the cleaning... The cleaning brush 706 moves up and down vertically; the second drive motor 7011 is started, the gear 7012 rotates, driving the annular gear 7013 to rotate, and the annular gear 7013 drives the annular plate 703 to rotate, so that the cleaning brush 706 moves up and down while rotating around the grid to clean the grid; after the grid is cleaned, the third drive motor 7041 is turned off, the extension end of the cleaning electric push rod 705 retracts, the cleaning brush 706 retracts, and the lifting electric cylinder 702 drives the annular plate 703 back to its original position; the orientation adjustment device 3 is started again to adjust the mounting frame 2 to the set orientation.

[0057] like Figure 14As shown, the control terminal 8 includes a main controller, a human-machine interface display screen, an information transmission module, a storage module, and a power supply module. The main controller is electrically connected to the human-machine interface display screen, the information transmission module, the storage module, the power supply module, and the following components: adjusting electric push rod 1 303, adjusting electric push rod 2 308, drive motor 1 401, bidirectional lead screw 501, clamping electric push rod 503, clamping motor 504, drive motor 2 7011, lifting electric cylinder 702, drive motor 3 7041, and cleaning electric push rod 705. The main controller is used to control the operation of the entire portable fire alarm quick-installation device. The human-machine interface display screen is used to set the orientation angle and height of the mounting frame 2, as well as the automatic operation control after the set values ​​are determined. The information transmission module is used for information transmission between the main controller and the orientation adjustment device 3, the telescopic device 4, the clamping device 5, and the cleaning device 7. The power supply module is used to provide a stable power supply to the control terminal 8. The storage module is used to store the operation information data of the entire portable fire alarm quick-installation device.

[0058] In this embodiment, when the fire alarm 9 needs to be installed on a pipe, the clamping device 5 is activated to clamp the entire portable fire alarm quick-installation device onto the pipe; when the fire alarm 9 is installed on a flat area, the suction cup 6 only needs to be attached to the flat area; after the entire portable fire alarm quick-installation device is fixed in place, the orientation adjustment device 3 and the telescopic device 4 are activated to adjust the orientation and height of the fire alarm 9 as needed.
