Description

Technical Field

[0001] This utility model relates to the field of air conditioning filter cleaning equipment, specifically a subway air conditioning filter cleaning device with automatic detection function. Background Technology

[0002] Since the beginning of the 21st century, rail transit has developed rapidly. Among them, the subway, as a core component of the modern urban transportation system, is important in many ways, such as alleviating traffic pressure, improving transportation efficiency, and promoting economic development.

[0003] In terms of alleviating traffic congestion, the subway, operating independently of the surface transportation system, effectively diverts passenger flow from private cars and public transport, especially during peak hours. Statistics show that the subway can carry 30,000-70,000 passengers per hour in one direction, with a transport speed of 35-80 km / h, 3-4 times that of ordinary buses, greatly relieving pressure on surface traffic. Regarding economic development, subway construction directly increases property values ​​along the line by 30%-50%, creating approximately 2,000 jobs per kilometer. In terms of improving urban efficiency, the subway extends travel radius and balances urban development, shortening the commuting distance between suburbs and the city center to 5-6 stops, effectively alleviating congestion in old urban areas. Furthermore, the formation of a subway network significantly improves urban operational efficiency, with public transport capacity far exceeding traditional modes such as buses and ride-hailing services. In terms of environmental protection and energy conservation, the electric-powered subway system reduces carbon emissions by more than 95% compared to traditional fuel-powered vehicles and reduces noise pollution, aligning with the concept of green and low-carbon development.

[0004] The advantages of subways are very obvious, and they are the preferred mode of transportation for people. Therefore, the cleanliness and maintenance of subways are closely related to people's lives. In particular, cleaning the subway air conditioning filters is very important for ensuring the health of passengers and maintaining the normal operation of equipment.

[0005] Cleaning the air conditioner filter helps maintain its proper function: a clogged filter obstructs airflow, severely impacting the cooling performance. Regular filter cleaning ensures smooth airflow and maintains the air conditioner's normal operation. Filter cleaning also prevents bacterial growth: filters that are not cleaned regularly are prone to harboring bacteria and viruses. If inhaled, these harmful substances can cause respiratory illnesses such as colds and coughs. Cleaning the filter effectively reduces bacterial growth, protecting human health. Furthermore, filter cleaning can reduce electricity costs: a clogged filter increases the air conditioner's operating resistance, leading to higher electricity bills. Regular filter cleaning reduces energy consumption and lowers electricity expenses.

[0006] Cleaning subway air conditioning filters plays a crucial role in preventing air conditioning system malfunctions. Clogged filters can lead to decreased air conditioning efficiency and even system failure. Regular filter cleaning ensures stable operation of the air conditioning system and avoids malfunctions. Furthermore, cleaning subway air conditioning filters can extend the lifespan of the air conditioner. The filter is a vital component of the air conditioning system; neglecting to clean it for a long time can damage it, thus affecting the overall lifespan of the air conditioner. Regular filter cleaning protects the filter from damage and extends the lifespan of the air conditioner.

[0007] Therefore, regularly cleaning the air conditioner filter is crucial for maintaining the normal operation of the air conditioner, protecting human health, reducing electricity costs, and extending the lifespan of the air conditioner.

[0008] However, the number of air conditioning filters in subways is very large, and cleaning is frequent and labor-intensive, posing a challenge to subway maintenance. This patent presents a subway air conditioning filter cleaning device with automatic detection function. It adopts a modular design, is easy to operate, reduces the labor intensity of workers, and improves cleaning efficiency. In particular, the automatic detection function ensures the quality of filter cleaning, thus guaranteeing the improvement of subway operation quality. Summary of the Invention

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 6 As shown, this utility model provides a subway air conditioning filter cleaning device with automatic detection function, including a flushing working chamber 2 and a control unit (not shown in the figure). The flushing working chamber 2 has a horizontal moving arm moving opening 208 at the top and a cleaned filter outlet 207 and a filter inlet 209 on both sides respectively. A horizontal moving track 3 is set at the top of the flushing working chamber 2. A horizontal moving motor 301 and a horizontal moving arm 302 slidably connected to the horizontal moving track 3 are provided on the horizontal moving track 3. The horizontal moving motor 301 controls the horizontal moving arm 302 to move along the direction of the horizontal moving track 3. A filter clamping manipulator 303 is connected to the horizontal moving arm 302. The filter clamping manipulator 303 is located in the flushing working chamber and is used to clamp the filter to be cleaned and drive it to move back and forth along the direction of the horizontal moving track 3.

[0032] The rinsing chamber 2 contains a roller drive motor 201, a filter screen moving clamping roller assembly A204, a filter screen moving clamping roller assembly B205, and a shaft-type dual sensor 4. The filter screen moving clamping roller assembly A204 and the filter screen moving clamping roller assembly B205 are spaced apart in the middle of the rinsing chamber 2. Both the filter screen moving clamping roller assembly A204 and the filter screen moving clamping roller assembly B205 include two rotatable cylindrical rollers, and the gap between the two cylindrical rollers forms a channel for the filter screen to be cleaned to pass through.

[0033] The axial dual sensor 4 is positioned near the filter outlet 207 after cleaning, such as... Figure 4 , Figure 5 As shown, the axial dual sensor 4 includes a cleanliness measurement laser sensor 403, a cleanliness measurement laser sensor housing 402, a claw-type humidity sensor 407, and a claw-type humidity sensor mounting block. The cleanliness measurement laser sensor housing 402 has an overall cylindrical structure. The cleanliness measurement laser sensor 403 is disposed on the side of the cleanliness measurement laser sensor housing 402. The claw-type humidity sensor 407 includes two humidity sensor cathode contact claws 405 and a humidity sensor anode contact claw 406 located between the two humidity sensor cathode contact claws 405. The humidity sensor cathode contact claws 405 and humidity sensor anode contact claws 406 are separated by a humidity sensor claw insulating grid 408 to prevent short circuit between the humidity sensor anode contact claw 406 and humidity sensor cathode contact claw 405 during testing. The claw-type humidity sensor mounting block is spliced ​​with the claw-type humidity sensor 407 to form a cylindrical structure coaxial with the cleanliness measurement laser sensor housing 402.

[0034] The cleanliness measurement laser sensor housing 402 is connected to the claw-type humidity sensor mounting block through a dual-sensor connector 404, and the axial dual sensor 4 is rotatably connected to the rinsing working chamber 2 through the axial dual sensor mounting shaft 401.

[0035] The roller drive motor 201 drives the filter screen moving clamping roller group A204, the filter screen moving clamping roller group B205, and the shaft-type dual sensor 4 to rotate through the transmission unit. The transmission unit includes a sprocket fixed on the central shaft of one of the cylindrical rollers in each filter screen moving clamping roller group, a sprocket fixed on the central shaft of the shaft-type dual sensor 4, and a sprocket fixed on the output shaft of the roller drive motor 201. The sprockets are connected to each other by a chain. The roller drive motor 201 drives the shaft-type dual sensor 4 and one of the cylindrical rollers in each filter screen moving clamping roller group to rotate through the chain and sprockets. A pulley is connected to the sprocket connected to one of the cylindrical rollers in each filter screen moving clamping roller group. The pulley is connected to the pulley connected to the other cylindrical roller in each filter screen moving clamping roller group by a belt. The rotation of one cylindrical roller drives the other cylindrical roller to rotate synchronously. The above transmission method is a structure well known to those skilled in the art and will not be described in detail in this application.

[0036] The inner wall of the rinsing chamber 2 is provided with cleaning nozzles A202 and B203 at intervals, and a filter dryer 206 is provided inside the rinsing chamber 2.

[0037] The transverse motor 301, the roller drive motor 201, the cleanliness measurement laser sensor 403, the claw humidity sensor 407, and the filter dryer 206 are all electrically connected to the control unit.

[0038] When using the above-mentioned device, the air conditioning filter to be cleaned is fed into the rinsing chamber 2 through the filter inlet 209. The filter clamping robot 303 clamps the upper edge of the air conditioning filter and moves it along the transverse track 3 within the rinsing chamber 2. During this process, the air conditioning filter passes through the gap between the two cylindrical rollers in the filter moving clamping roller group A204 and filter moving clamping roller group B205. The surface of the air conditioning filter will rub against the surface of the cylindrical rollers. The cylindrical rollers and the filter clamping robot 303 work together to guide the air conditioning filter to move back and forth stably within the rinsing chamber 2. The cleaning spray nozzles A202 and B203 spray water to clean the surface of the air conditioning filter. The filter dryer 206 rinsing the air conditioning filter... The filter screen surface is dried. When the cleanliness measurement laser sensor 403 in the axial dual sensor 4 comes into contact with the air conditioning filter screen surface, it will detect the cleanliness of the filter screen surface. When the cathode and anode contact grippers on the claw humidity sensor 407 in the axial dual sensor 4 come into contact with the air conditioning filter screen surface, they will detect the surface humidity. Filter screens with qualified test values ​​will be sent out of the cleaned filter screen outlet 207 from the rinsing work chamber 2 under the combined action of the filter screen holding robot 303 and the filter screen moving clamping roller group. Filter screens with unqualified test values ​​will be moved backward and back into the rinsing work chamber 2 under the combined action of the filter screen holding robot 303 and the filter screen moving clamping roller group for re-cleaning until the test data of the axial dual sensor 4 is qualified.

[0039] The cleaning nozzle A202 is located between the filter screen moving clamping roller group A204 and the filter screen inlet 209 to be cleaned, and the cleaning nozzle B203 is located between the filter screen moving clamping roller group A204 and the filter screen moving clamping roller group B205.

[0040] The cylindrical structure formed by the housing 402 of the cleanliness measurement laser sensor and the claw-type humidity sensor 407 has the same dimensions as the cylindrical roller. This simplifies the installation process of the shaft-type dual sensor 4 and improves the quality assurance of filter cleaning.

[0041] The cylindrical roller is covered with a non-woven fabric layer to increase the friction between the cylindrical roller and the air conditioning filter, so that the cylindrical roller can guide the air conditioning filter while cleaning the surface of the air conditioning filter.

[0042] A base 1 is installed at the bottom of the rinsing chamber 2, and the bottom of the rinsing chamber 2 is connected to the interior of the base 1. The base 1 contains a wastewater tank 101 and a wastewater collection funnel 102, with the funnel 102 located between the wastewater tank 101 and the rinsing chamber 2. A wastewater filter screen 103 is installed inside the wastewater tank 101. Wastewater in the rinsing chamber 2 can be collected into the wastewater tank 101 through the wastewater collection funnel 102, and the wastewater filter screen 103 can trap solid impurities in the wastewater.

[0043] The aforementioned device was proposed based on the analysis of the operating characteristics of subway vehicles and the health needs of passengers. This device makes full use of automation technology, improves the work efficiency of staff and reduces costs, enhances the safety of staff and reduces labor intensity. Furthermore, by designing and introducing a structure of axial dual sensors 4, it simplifies the installation and detection process. The modular design makes the process simple, safe, and stable, providing a solution for achieving scientific, safe, and automated cleaning of subway air conditioning filters and detection of cleaning quality.

[0044] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made in accordance with the claims of this utility model should still fall within the patent coverage of this utility model.
