Description

Technical Field

[0001] This utility model relates to the field of fire escape equipment technology, and in particular to a modular wall-mounted rescue system for buildings. Background Technology

[0002] When a fire breaks out in a high-rise building, elevators stop operating, and thick smoke may spread up to higher floors along the safety passages. People who do not escape immediately may be trapped inside, sometimes finding it difficult to continue descending the stairwells. Although fire brigades respond quickly, fire trucks are relatively large and can be restricted in the complex road conditions of residential areas, as well as by limited operating space, significantly reducing their rescue capabilities. Existing building exterior escape systems also suffer from problems such as large size, bulkiness, the need for dedicated roads and sites, and the requirement for professional firefighters to operate them. Furthermore, the upgrading of fire protection facilities in older residential areas is progressing slowly due to these issues. Therefore, improving the portability, intelligence, and ease of operation of building rescue equipment is an urgent problem that needs to be solved by those skilled in the art. Utility Model Content

[0019] The remote control allows for wireless long-distance control of the power unit's up / down movement, acceleration / deceleration, stopping, and emergency braking. It also controls the opening and closing of the inner electric folding door of the basket. Rescuers can guide and communicate with escaping personnel via the intercom camera on the basket. Using the remote control and intercom camera eliminates the need for specialized rescue personnel to enter the basket for operation, reducing the system's upstream load, lowering the motor's power requirements and weight, and providing more escape routes. Even trained property management personnel can operate the system, reducing rescue difficulty. When the wireless signal is poor, the remote control can be connected to the building's ground floor electrical distribution unit via a cable, using powerline modem technology on the wall-mounted rail to control the power unit, electric folding door, and video intercom probe.

[0020] The beneficial effects of this utility model are as follows: This utility model provides a modular wall-mounted rescue system for buildings, which adopts five modules: wall-mounted track, connecting crossbar, power device, hanging basket, and remote control. Among them, the wall-mounted track is a fixed module that is fixed to the side of the escape window of the building, while the connecting crossbar, power device, hanging basket, and remote control are four movable modules that can be shared by the community. In the event of a fire, the daily-calibrated connecting crossbar, power device, hanging basket, and remote control can be transported to the ground floor of the corresponding escape window by electric or manual light tricycle for rapid assembly and rescue. The system has the characteristics of modularity, lightweight, intelligence, and ease of operation, and can promptly rescue victims in the event of a building fire or other disaster.

[0055] Installation and operation process:

[0056] In the event of a fire or other disaster, evacuees should first move to the relatively safe escape window 8 and notify the property management / fire duty personnel of the specific building, apartment number, and escape window. If there is a fire IoT system, the distress button at escape window 8 can be pressed to send a signal. Then, take protective measures and wait.

[0057] After receiving a distress signal, the community property management / fire duty personnel will use an electric or manual light tricycle to transport the daily-calibrated connecting crossbar 2, power unit 3, hanging basket 4 and remote control 5 to the ground floor of the corresponding building escape window 8.

[0058] First, remove the connecting crossbar 2. Insert the first three-way wheel set 203 and the second three-way wheel set 204 into the concave grooves of the first channel steel 104 corresponding to the first slot 118 and the second slot 119. Loosen the quick tensioner 212 on the connecting crossbar 2. Move the third three-way wheel set 205 slightly towards the quick tensioner 212, and then insert it into the concave groove of the second channel steel 105 through the third slot 120. Tighten the quick tensioner 212 and fix it with the fixing hook 213 of the quick tensioner 212. Connect and install the safety rope 601 to the hook 218 on the connecting crossbar 2 through the hook 602.

[0059] When installing the power unit 3, the bottom wedge 316 of the first motor 301 is aligned with the motor fixing slot 209 of the motor fixing platform 208, and the position of the first motor 301 is fixed with quick-fixing bolts. The transmission gear 303 is inserted through the fourth slot 121 and engages with the gear rail 107. At this time, the power supply rail contactor 307 and the power supply rail cleaner 308 also engage with the power supply rail 108 on the wall-mounted rail 1, completing the installation of the power unit 3. At this time, although the bottom positioning micro switch 315 on the power unit 3 touches the bottom positioning rod 122, the program is set so that the first touch after power-on will not open the outer electric folding door 405 of the hanging basket 4. Even if the outer electric folding door 405 is accidentally touched and opened, the outer electric folding door 405 will automatically close when the hanging basket 4 moves upward.

[0060] When installing the hanging basket 4, hang the hanging basket 4 into the hanging basket fixing groove 214 on the connecting crossbar 2, slide it towards the hanging basket positioning groove 215 so that the hook 410 is embedded in the hanging basket positioning groove 215, and use quick fixing bolts to fix the hanging basket 4 on the connecting crossbar 2. Connect the hanging basket cable 409 to the power device cable 311 to complete the installation of the hanging basket 4.

[0061] Property management / fire safety personnel use the fire key to open the power distribution unit 7, turn on the power switch to connect the power supply, and turn on the power switches on the power unit 3 and remote control 5. They then observe the various indicator lights on the remote control 5 to check the system's self-test status. After the system self-test passes, they push the joystick 502 on the remote control 5 upwards. The first motor 301 drives the transmission gear 303 to move upwards along the gear rail 107. At this time, the connecting crossbar 2 and the hanging basket 4 move upwards together, and the second motor 607 inside the safety rope retractor 6 automatically retracts the safety rope 601.

[0062] Observe the display screen 503 on the remote control 5. When the positioning rod 412 on the hanging basket 4 is approximately aligned with the red horizontal bar in the positioning mark 111 of the floor to be rescued, slightly adjust the rocker arm 502 up or down so that the Hall sensor probe 314 on the first motor 301 is aligned with the Hall sensor magnet 110 on the wall-mounted track 1. At this time, the positioning indicator light on the remote control 5 will turn from red to green. Push the rocker arm 502 toward the display screen 503 to brake it. Press the positioning switch 507 so that the positioning latch 313 of the first motor 301 extends into the positioning grooves 109 on the first channel steel 104 and the second channel steel 105 respectively (the corresponding indicator light turns from red to green after the latch is in place). Press the inner electric folding door switch 509. Open the inner electric folding door 404 of the hanging basket 4 (the inner electric folding door 404 cannot be opened if the positioning latch 313 is not inserted into the positioning groove 109). After the inner electric folding door 404 is opened, the property management / fire duty personnel press the intercom switch 505 to communicate with the escapees and remind them of the precautions (mainly that the number of people and the total weight must not exceed the approved number of people and the load capacity). Instruct them to enter the hanging basket 4 in an orderly and slow manner. After the escapees enter the hanging basket 4, lift the inner electric folding door switch 509 to close the inner electric folding door 404. While the rocker arm 502 is pushed towards the display screen 503 to brake, lift the positioning switch 507 to make the positioning latch 313 exit the positioning groove 109 (at this time, the corresponding indicator light changes from green to red).

[0063] The crank 502 is returned to center and pushed downwards, causing the first motor 301 to drive the connecting crossbar 2 and the hanging basket 4 downwards. Simultaneously, the safety rope retractor 6 automatically releases the safety rope 601. When the hanging basket 4 reaches the bottom of the building, the bottom positioning microswitch 315 on the power unit 3 contacts the bottom positioning rod 122 on the first channel steel 104. After the bottom positioning microswitch 315 is pressed down, the outer electric folding door 405 of the hanging basket 4 automatically opens, allowing the escapee to leave the hanging basket 4. When it is necessary to go up again for rescue, the bottom positioning microswitch 315 automatically springs up after leaving the bottom positioning rod 122, and the outer electric folding door 405 of the hanging basket 4 automatically closes, repeating the above process.

[0064] To prevent damage and climbing, guardrails are installed around the first channel steel 104, the second channel steel 105, and the escape window 8 of the ground floor building, without affecting rescue operations.

[0065] Special Circumstances Handling:

[0066] 1. When the power supply rail 108 has poor contact, use the emergency battery 305 to drive the power supply rail cleaner 308 to clean the power supply rail 108, or use the emergency battery 305 to provide emergency power to the system for a short time.

[0067] 2. When the wireless signal is poor / failed, switch to manual control of the power distributor 7, or connect the remote control 5 to the power distributor 7 with a connecting cable and use the remote control 5 to control the system. Both methods use powerline modem (powerline adapter) technology through the power supply rail 108 to control the power unit 3, the inner electric folding door 404, and the intercom camera 408 (when the power distributor 7 is manually controlled, the intercom camera 408 only has intercom function).

[0068] 3. If the first motor 301 or the power supply track 108 is damaged, and the basket 4 and other components are still in mid-air, the basket 4 and other components can be stopped from falling by pressing the emergency brake lever 606 on the safety rope retractor 6. At the same time, the emergency power-off micro switch 611 is pressed down by the handle of the emergency brake lever 606 to cut off the power supply to the system track. Slightly lift the emergency brake lever 606 (the emergency power-off micro switch 611 is still pressed down to cut off the power) to slowly release the safety rope 601, so that the basket 4 and other components slowly descend to the ground. If the basket 4 and other components are on the ground, and the second motor 607 in the safety rope retractor 6 has sufficient power, the second motor 607 can be manually operated to drive the basket 4 and other components to move up or down through the safety rope 601.

[0069] When the joystick 502 of the remote control 5 is in a stopped or braked state, the rope tension detector 610 receives moderate tension from the safety rope 601, and the second motor 607 is in a stopped state. When the joystick 502 is upward, the power unit 3, the basket 4, the connecting crossbar 2, etc., move upward. At this time, the safety rope 601 is in a slack state, and the tension received by the rope tension detector 610 from the safety rope 601 is relatively small. The second motor 607 rotates clockwise, driving the winch 608 to rotate and retract the safety rope 601. When the joystick 502 is downward, the power unit 3, the basket 4, the connecting crossbar 2, etc., move downward. At this time, the safety rope 601 is in a taut state, and the tension received by the rope tension detector 610 from the safety rope 601 is relatively large. The second motor 607 rotates counterclockwise, driving the winch 608 to rotate and release the safety rope 601.

[0070] The first motor 301 and the second motor 607 need to be adjusted to the same speed range so that the speed at which the safety rope retractor 6 automatically retracts and releases the safety rope 601 is coordinated with the up-and-down running speed of the power unit 3, the hanging basket 4, and other components to prevent internal friction. However, if the power unit 3, the hanging basket 4, etc., descend too quickly and exceed the speed range due to malfunction or other reasons, the second brake 605 of the safety rope retractor 6 will automatically limit the speed and control the release speed of the safety rope 601 to ensure that the power unit 3, the connecting crossbar 2, and the hanging basket 4 are safely lowered to the ground.

[0071] Example 2:

[0072] like Figure 10-12As shown, the system still consists of five modules: wall-mounted track 1, connecting crossbar 2, power unit 3, hanging basket 4, and remote controller 5. When economic conditions, installation width requirements, etc., are insufficient, the structure of hanging basket 4 and remote controller 5 remains unchanged. The positioning locking tongue 313 in the power unit 3 is reduced from two to one. The first channel steel 104 and the second channel steel 105 are integrally processed into an I-beam 130. The width of the I-beam 130 is spaced away from the first channel steel 104 and the second channel steel 105 in Embodiment 1. With the width reduced, the distance between the second three-way wheel set 204 and the third three-way wheel set 205 on the connecting crossbar 2 is reduced. The first three-way wheel set 203, the second three-way wheel set 204 and the third three-way wheel set 205 are set in the concave groove of the I-beam 130 to form a three-point support. The bottom of the I-beam 130 is provided with a first slot 118, a second slot 119 and a third slot 120 to facilitate the installation of the first three-way wheel set 203, the second three-way wheel set 204 and the third three-way wheel set 205.

[0073] The side wall of the I-beam 130 is provided with a toothed rail 107 and a power supply rail 108. The first motor 301 is provided with a power supply rail contactor 307 and a power supply rail cleaner 308 that cooperate with the power supply rail 108. When installing the power device 3, the bottom wedge block 316 of the first motor 301 is aligned with the motor fixing slot 209 of the motor fixing platform 208 and the position of the first motor 301 is fixed with quick fixing bolts. The transmission gear 303 directly engages with the toothed rail 107. At this time, the power supply rail contactor 307 and the power supply rail cleaner 308 also match the power supply rail 108 on the I-beam 130.

[0074] Compared with the connecting crossbar 2 in Embodiment 1, the connecting crossbar 2 in Embodiment 2 has an additional balance wheel 206 on the side away from the escape window 8 to ensure that the connecting crossbar 2 and the hanging basket 4 fit the wall and the escape window 8.

[0075] The structures of the top pulley block 604, safety rope 601, the protective cover outside the safety rope 601, and the safety rope retractor 6 are eliminated. The manual control function in the power distribution unit 127 is changed to an optional function.

[0076] In this invention, directions and references (e.g., up, down, left, right, etc.) are used only to aid in the description of features in the drawings. Therefore, the following specific embodiments are not intended to be restrictive, and the scope of the claimed subject matter is defined solely by the appended claims and their equivalents.

[0077] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the scope of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
