Description

Technical Field

[0001] This application relates to the field of charging equipment technology, and in particular to a charging device with fire-fighting function. Background Technology

[0002] Electric bicycle charging stations are widely used in urban communities, office buildings, and other areas, providing convenient charging services for electric bicycles. With the rapid increase in the number of electric bicycles, the demand for charging stations is also increasing, and their safety has become a focus of public concern. Current technologies require charging stations not only to meet basic charging functions but also to possess certain safety protection capabilities to cope with possible accidents, thereby protecting the safety of users and the surrounding environment.

[0003] In related technologies, the following methods are commonly used to improve the safety of charging devices: one is to install independent fire-fighting equipment, such as fire extinguishers or fire hydrants, near the charging device for manual fire suppression; another is to place the charging device in an open area to reduce the possibility of fire spread; and yet another is to install a simple smoke detector inside the charging device to detect smoke in the early stages of a fire and issue an alarm. While these methods improve safety to some extent, they suffer from slow response times and low levels of automation.

[0004] However, charging devices in related technologies often lack effective automatic fire suppression capabilities in the event of a fire. When a fire occurs, traditional methods are insufficient for a rapid response and firefighting operation, potentially leading to the spread of the fire and causing greater losses. Therefore, achieving rapid response and automatic fire suppression in charging devices during a fire has become an urgent technical problem to be solved. Utility Model Content

[0005] To address the technical challenge of improving the rapid response of charging devices in the event of a fire, this application provides a charging device with fire-fighting capabilities, employing the following technical solution:

[0006] A charging device with fire-fighting function includes a column, a top box disposed at the top of the column, a charging socket installed on the top box, a sprinkler assembly for fire fighting, and a sensing and control assembly for detecting smoke and controlling the sprinkler. The sensing and control assembly includes a smoke sensor installed on the top box, and the sprinkler assembly includes sprinklers connected to a pressurized water source. The sprinklers are oriented towards the area where the electric bicycle is placed. When the smoke sensor detects smoke, the sprinkler assembly automatically sprays water.

[0007] By adopting the above technical solution, the charging device includes a column, a top box, a sprinkler assembly, and a sensing and control assembly. The top box is equipped with a charging socket for charging electric bicycles. When the smoke sensor detects smoke, the sprinkler assembly can automatically spray water onto the area where the charging vehicle is placed, effectively preventing the spread of fire and protecting the safety of the charging device and the surrounding environment.

[0008] Optionally, the spray assembly further includes a water storage tank placed inside the column, a water pump installed inside the column and connected to the water storage tank, and a spray pipe connecting the water pump and the sprayer. The outlet of the water pump is connected to the spray pipe, and the inlet of the water pump is connected to the inner cavity of the water storage tank near the bottom through an inlet pipe.

[0009] By adopting the above technical solution, the charging device incorporates a water storage tank and a water pump within the column, enabling local water storage and on-demand supply, thus improving fire response speed and reliability. The water pump is connected to the water storage tank via an inlet pipe, ensuring a stable pressurized water supply and enabling continuous spraying operations, thereby enhancing firefighting effectiveness.

[0010] Optionally, the spray assembly further includes a support cover with openings at both ends. One end of the support cover is fixedly connected to the column, and the other end is fixedly connected to the top box. Several sprayers are installed on the side wall of the support cover. The sprayers are 120-degree conical water mist nozzles, and the several sprayers are connected to the spray pipe.

[0011] By adopting the above technical solution, the setting of the support cover enhances the structural stability of the sprinkler assembly, ensuring that the sprinkler can be reliably installed on the charging device. The arrangement of several 120-degree conical water mist nozzles helps to make the spraying range larger and the spraying effect more uniform, effectively covering the charging vehicle placement area and improving the effect and reliability of fire sprinkler.

[0012] Optionally, the sensing and control component further includes a control module electrically connected to the smoke sensor. When the smoke sensor detects smoke, the control module controls the water pump to start pumping water and sends an alarm signal to a monitoring center for remote monitoring of the charging device.

[0013] By adopting the above technical solution, when the smoke sensor detects smoke, the control module can promptly control the water pump to start, realizing automatic sprinkler fire extinguishing function and effectively reducing fire risk. Simultaneously, the control module can also send an alarm to the monitoring center, facilitating remote monitoring personnel to promptly understand the fire situation and take appropriate measures, thus improving the safety and reliability of the charging device.

[0014] Optionally, the top box is also equipped with an alarm light for smoke warning, which is electrically connected to the control module.

[0015] By adopting the above technical solution, when the smoke sensor detects smoke, the control module can not only control the water pump to start spraying for fire extinguishing, but also simultaneously trigger the alarm lights to achieve a visual warning effect, alerting nearby personnel to the fire situation and improving safety. This solution enhances the warning function of the charging device in the event of a fire, making fire prevention measures more comprehensive.

[0016] Optionally, the top box includes a top wall, a side wall, and a water shield. The side wall has a first mounting hole for installing the charging socket. The water shield is arranged around the first mounting hole and is sealed and fixed to the side wall. The side wall also has a receiving cavity for accommodating the smoke sensor. The bottom of the receiving cavity has a second mounting hole for installing the smoke sensor.

[0017] By adopting the above technical solution, the charging socket achieves waterproofing by setting a water-retaining cover around its top perimeter, effectively preventing rainwater or other liquids from entering the charging socket and improving the safety of the charging device. Meanwhile, the smoke sensor is installed in the second mounting hole at the bottom of the housing cavity. This design protects the smoke sensor from external environmental influences while ensuring its accurate detection of smoke signals.

[0018] Optionally, the water storage tank is further provided with a water storage pipe for connecting to an external water source. A first electromagnetic water valve is provided on the water storage pipe, and a second electromagnetic water valve is provided on the water inlet pipe. The first electromagnetic water valve and the second electromagnetic water valve are respectively electrically connected to the control module.

[0019] By adopting the above technical solution, when the water in the storage tank is insufficient, the first electromagnetic water valve opens, and the water storage pipe is connected to an external water source to replenish the water, ensuring that the storage tank always has enough fire-fighting water. Under normal working conditions, the second electromagnetic water valve controls the opening and closing of the water inlet pipe to prevent accidental water loss from the storage tank. At the same time, it achieves automated control through electrical connection with the control module, improving the reliability and safety of the system.

[0020] Optionally, the water storage tank is also equipped with a water level sensor for detecting the water level, and the water level sensor is electrically connected to the control module.

[0021] By adopting the above technical solution, when the water level in the storage tank changes, the water level sensor can promptly detect the water level status and transmit the signal to the control module. The control module determines whether the storage tank needs replenishment or issues a low water level alarm based on the received signal, thereby ensuring that the sprinkler assembly has sufficient water for fire sprinkler operation in the event of a fire, improving the overall fire-fighting reliability of the charging device. This solution effectively avoids the problem of fire-fighting function failure due to insufficient water in the storage tank, enhancing the safety performance of the equipment.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. By detecting smoke through a smoke sensor and triggering the sprinkler assembly to automatically spray, the charging device can respond quickly when a fire hazard is detected, effectively improving the timeliness and reliability of the fire protection function;

[0024] 2. The sprinkler assembly, which combines a water tank, a water pump, and sprinkler pipes, ensures a stable supply of fire-fighting water. At the same time, the 120-degree conical water mist nozzles provide full coverage of the charging vehicle's placement area, improving fire-fighting efficiency.

[0025] 3. The control module integrates the linkage control of smoke sensors and sprinkler components, which can not only automatically start the water pump for fire extinguishing, but also send alarms to the monitoring center, enhancing the safety and remote management capabilities of the charging device.

[0034] The following combination Figures 1 to 6 This application will be described in further detail.

[0035] This application discloses a charging device with fire-fighting function.

[0036] A charging device with fire-fighting function. (See reference) Figure 1 and Figure 2 The system includes a column 1, a top box 2, a charging socket 3, a sprinkler assembly 4, and a sensor control assembly 5. The column 1 and top box 2 are made of sheet metal. The bottom of the column 1 has a base plate 11 with fixing holes. Expansion bolts are inserted through these holes to fix the column 1 to the ground. A tailgate 12 is also provided on one side wall 22 of the column 1 for convenient equipment inspection and maintenance. The top box 2 is fixedly installed on the top of the column 1. The charging socket 3 is fixedly installed on the side wall 22 of the top box 2. The charging socket 3 is waterproof and has a waterproof cover 31. In this embodiment, there are two charging sockets 3, arranged opposite each other on the side wall 22 of the top box 2. In other embodiments, there is only one charging socket 3. The sprinkler assembly 4 is used for fire suppression, and the sensor control assembly 5 is used for smoke detection and control of the sprinkler activation. Component 5 includes a smoke sensor 51 installed on the side wall 22 of the top box 2. It should be noted that the charging socket 3 is electrically connected to the sensing and control component 5. When the smoke sensor 51 detects smoke, the sensing and control component 5 first controls the disconnection of the charging power supply connected to the charging socket 3 to improve the safety of subsequent fire protection. The sprinkler component 4 includes a sprinkler 41 connected to a pressurized water source. The sprinkler 41 faces the area where the charging vehicle is placed. When the smoke sensor 51 detects smoke, the sprinkler component 4 automatically sprays water. The charging device forms a stable support structure through the column 1 and the top box 2, which occupies a small area. The charging socket 3 is installed on the top box 2 for charging electric bicycles. When the smoke sensor 51 detects smoke, the sprinkler component 4 can automatically spray water on the area where the charging vehicle is placed, effectively preventing the spread of fire and protecting the safety of the charging device, the charging electric bicycle, and the surrounding environment.

[0037] Reference Figure 3 and Figure 4The sprinkler assembly 4 also includes a water storage tank 42, a water pump 43, a sprinkler pipe 44, and an inlet pipe 45. The water storage tank 42 is placed inside the column 1 and is made of engineering plastic. It is used to store fire-fighting water. The water pump 43 is installed on the inner wall of the column 1 and connected to the water storage tank 42. The outlet of the water pump 43 is connected to the sprinkler 41 through the sprinkler pipe 44, and the inlet of the water pump 43 is connected to the inner cavity of the water storage tank 42 near the bottom through the inlet pipe 45. The charging device is set inside the column 1 with the water storage tank 42 and the water pump 43, realizing local storage and on-demand supply of water, improving the fire response speed and reliability. The water pump 43 is connected to the water storage tank 42 through the inlet pipe 45 to ensure a stable pressurized water supply, enabling continuous sprinkler operation and helping to improve the fire-fighting effect.

[0038] Reference Figures 3 to 5 The spray assembly 4 also includes a support cover 46, which has openings at both ends. The support cover 46 is made of sheet metal. An ear plate 461 is provided on one end of the support cover 46 near the column 1. The ear plate 461 is pressed and fixed to the column 1 by screws. A flange 462 is provided on the other end of the support cover 46. The top box 2 is fastened to the flange 462 and fixedly connected to the top box 2 by screws. Several threaded holes are provided on the side wall 22 of the support cover 46. The sprayer 41 is screwed into the threaded holes and fixedly installed on the support cover 46. In this embodiment, the number of threaded holes is three. Other embodiments of this application... The number of threaded holes is 2 or 4. The sprinkler 41 is a 120-degree conical water mist nozzle. Several sprinklers 41 are connected to the sprinkler pipe 44. The setting of the support cover 46 enhances the structural stability of the sprinkler assembly 4, ensuring that the sprinkler 41 can be reliably installed on the charging device. At the same time, it can separate the sprinkler assembly 4 from the charging socket 3 on the top box 2, improving the safety of the sprinkler operation. The arrangement of several 120-degree conical water mist nozzles of the sprinkler 41 helps to make the spraying range larger and the spraying effect more uniform, effectively covering the charging vehicle placement area, and improving the effect and reliability of fire sprinkler.

[0039] Reference Figure 5 The sensing and control component 5 also includes a control module 52. In this embodiment, the control module 52 is installed on the inner wall of the column 1. In other embodiments, the control module 52 is installed inside the top box 2. The control module 52 is electrically connected to the smoke sensor 51. When the smoke sensor 51 detects smoke, the control module 52 controls the water pump 43 to start pumping water and sends an alarm to the monitoring center for remote monitoring of the charging device. When the smoke sensor 51 detects smoke, the control module 52 can promptly control the water pump 43 to start, realizing the automatic sprinkler fire extinguishing function and effectively reducing the risk of fire. At the same time, the control module 52 can also send an alarm to the monitoring center, which facilitates remote monitoring personnel to understand the fire situation in a timely manner and take corresponding measures, improving the safety and reliability of the charging device.

[0040] Reference Figure 2 The top box 2 is also equipped with a smoke warning light 53, which is electrically connected to the control module 52. When the smoke sensor 51 detects smoke, the control module 52 not only controls the water pump 43 to start spraying for fire extinguishing, but also simultaneously triggers the alarm light 53, thereby achieving a visual warning effect, alerting surrounding personnel to the fire situation, and improving safety. This solution enhances the warning function of the charging device in the event of a fire, making fire prevention measures more comprehensive.

[0041] Reference Figure 1 and Figure 6 The top box 2 includes a top wall 21, a side wall 22, and a water-retaining cover 23. The side wall 22 has a first mounting hole 221 for installing the charging socket 3. The water-retaining cover 23 is arranged around the first mounting hole 221 and sealed and fixed to the side wall 22. The side wall 22 also has a receiving cavity 222 for accommodating the smoke sensor 51. The bottom of the receiving cavity 222 has a second mounting hole 223 for installing the smoke sensor 51. The charging socket 3 achieves waterproofing by using the water-retaining cover 23 around the top of the first mounting hole 221, effectively preventing rainwater or sprayed fire water from entering the charging socket 3 and improving the safety of the charging device. Simultaneously, the smoke sensor 51 is installed in the second mounting hole 223 at the bottom of the receiving cavity 222. This design protects the smoke sensor 51 from external environmental influences while ensuring it can accurately detect smoke signals.

[0042] Reference Figure 4 The water storage tank 42 is also equipped with a water storage pipe 421 for connecting to an external water source. A first electromagnetic water valve 47 is installed on the water storage pipe 421, and a second electromagnetic water valve 48 is installed on the water inlet pipe 45. The first electromagnetic water valve 47 and the second electromagnetic water valve 48 are electrically connected to the control module 52 respectively. When the water in the water storage tank 42 is insufficient, the first electromagnetic water valve 47 opens, and the water storage pipe 421 is connected to an external water source to supplement the water, ensuring that the water storage tank 42 always has sufficient fire-fighting water. Under normal working conditions, the second electromagnetic water valve 48 controls the opening and closing of the water inlet pipe 45 to prevent accidental water loss from the water storage tank 42. At the same time, it achieves automatic control through electrical connection with the control module 52, improving the reliability and safety of the system.

[0043] Reference Figure 4The water storage tank 42 is also equipped with a water level sensor 49 for detecting water level. The water level sensor 49 is electrically connected to the control module 52. When the water level in the water storage tank 42 changes, the water level sensor 49 can detect the water level status in a timely manner and transmit the signal to the control module 52. The control module 52 determines whether the water storage tank 42 needs to be replenished or issues a low water level alarm based on the received signal, thereby ensuring that the sprinkler assembly 4 has sufficient water for fire sprinkler spraying in the event of a fire, improving the fire protection reliability of the entire charging device. This solution effectively avoids the problem of fire protection function failure due to insufficient water in the water storage tank 42, enhancing the safety performance of the equipment.

[0044] The operating principle of a charging device with fire-fighting function is as follows: When the charging plug of an electric bicycle is inserted into the charging socket 3, and smoke appears during the charging process of the electric bicycle battery, the smoke sensor 51 detects the smoke and sends a smoke signal to the control module 52. Upon receiving the smoke signal, the control module 52 first disconnects the charging power supply to the charging socket 3, opens the second electromagnetic water valve 48, and starts the water pump 43. Water from the storage tank 42 is drawn and pressurized by the water pump 43 and sprayed from the sprinkler 41 through the sprinkler pipe 44, thus extinguishing the fire. The area emitting smoke from the bicycle is sprayed with water to extinguish the fire. At the same time, the control module 52 turns on the alarm light 53 and sends an alarm signal to the remote monitoring center. After the fire is extinguished, the control module 52 controls the power supply of the water pump 43 to be cut off. When the water level sensor 49 detects that the water level in the water tank 42 is insufficient, the control module 52 controls the opening of the first electromagnetic water valve 47. The external water source adds water to the water tank 42 through the water storage pipe 421. When the water level sensor 49 senses that the water level is full, the control module 52 controls the closing of the first electromagnetic water valve 47 and the second electromagnetic water valve 48.

[0045] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
