Description

Technical Field

[0001] The utility model belongs to the technical field of drainage devices, and in particular relates to a subway ventilation and air-conditioning drainage device. Background Art

[0002] The ventilation and air-conditioning system of the subway car is an important part to ensure the comfort of passengers and the quality of the internal environment of the train. When the air-conditioning is running, a large amount of condensed water will be generated. This water is generally discharged directly onto the track surface outside the subway car, which not only causes a waste of this part of water, but also easily pollutes the environment. For this reason, we propose a subway ventilation and air-conditioning drainage device. Utility Model Content

[0003] In view of the above problems, the purpose of the utility model is to provide a subway ventilation and air-conditioning drainage device, which can recycle and purify the condensed water generated by the ventilation and air-conditioning of the subway car, and can discharge the recovered condensed water into a bucket carried by the staff responsible for cleaning the car when they are working. This not only saves the staff from the work of carrying cleaning water into the car, but also plays a role in recycling the condensed water.

[0004] To achieve the above objectives, the utility model provides the following technical solutions: a subway ventilation and air-conditioning drainage device, comprising a subway car, an air-conditioning main unit is installed on the top of the subway car, a containing box is provided at the bottom of one side inside the subway car, a water outlet pipe is connected to one side of the air-conditioning main unit, a slide rail is installed inside the containing box, the slide rail is slidably connected to the slide bar, a supporting plate is provided on the side of the slide bar, a water tank is installed on the top of the supporting plate, a filtering device is provided on the top of the water tank, the top of the filtering device is connected to the bottom end of the water outlet pipe, a water pump is installed on the side of the water tank, the other end of the water pump is connected to the drainage pipe, an infrared sensing device is also installed on the side of the water tank, an ultraviolet disinfection lamp is installed on the inner side of the water tank, the filtering device comprises a filtering device housing threadedly connected to the top of the water tank, a filter element insertion installation frame is inserted and installed on the inner side of the filtering device housing, an activated carbon filter element and a molecular sieve filter element are inserted and installed on the inner side of the filter element insertion installation frame, and a control panel is installed on the front of the water tank.

[0005] The beneficial effects of the utility model are as follows: the condensed water generated by the air-conditioning main unit is transported to the inside of the filter device through the outlet pipe, and after being adsorbed and filtered by the activated carbon filter element and the molecular sieve filter element, it is discharged into the water tank. The water level height inside the water tank is detected by the water level sensor, and the water level height in the water tank is displayed in real time by the water level indicator light. At the same time, the ultraviolet disinfection lamp can disinfect the water inside the water tank for subsequent safe use. When the subway car needs to be cleaned, the cleaning staff opens the door of the storage box and puts the bucket on the anti-slip mat above the bucket placement area. After the infrared sensing device detects the placement of the bucket, the control panel automatically Control the water pump to pump the water in the water tank into the bucket through the drain pipe. When the water in the bucket is about to be full, the bucket can be taken out. After the infrared sensing device detects that the bucket has been removed, the control panel automatically controls the water pump to stop running. After the bucket is taken out, the water in the bucket can be used to clean the car, thereby purifying, recycling and utilizing the air-conditioning waste water, effectively saving water resources. At the same time, the cleaning staff no longer need to collect water and carry the bucket full of water before entering the car. They only need to transport the cleaned waste water out through the bucket. In the process of collecting water, the water pump can be automatically controlled, which facilitates the water collection operation.

[0006] To supply air to the cabin:

[0007] As a further improvement of the above technical solution: an air outlet is provided on the inner top of the subway car, and a ventilation duct is connected between the air outlet and the air-conditioning main unit.

[0008] The air conditioning host of the device supplies air to the air outlet through the ventilation duct, and transmits cold air or hot air to the interior of the subway car through the air outlet.

[0009] To lock the rails and sliders:

[0010] As a further improvement of the above technical solution: a screw hole is provided downwardly through the top of the slide rail and is threadedly connected with a locking bolt.

[0011] After the locking bolts are tightened, the slide rails and the slide bars can be locked.

[0012] To limit the insertion of the filter element into the installation frame:

[0013] As a further improvement of the above technical solution: a rotation limit plate is rotatably installed on the front side of the filter device housing.

[0014] The beneficial effect of this improvement is that the rotating limit plate can limit the insertion of the filter element into the installation frame to prevent it from sliding outwards.

[0015] To prevent the bucket from sliding when collecting water:

[0016] As a further improvement of the above technical solution: a water bucket placement area is provided inside the containing box, and a non-slip mat is provided on the top of the water bucket placement area.

[0017] The beneficial effect of this improvement is that the bucket placement area is used to place the bucket for collecting water, and the anti-skid mat can prevent the bucket from sliding when collecting water.

[0018] To help staff understand the water level in the tank:

[0019] As a further improvement of the above technical solution: a water level sensor is installed on the inner side of the water tank, and a water level indicator light is installed on the outer side of the water tank.

[0020] The beneficial effect of this improvement is that the water level inside the water tank is detected by the water level sensor, and the water level inside the water tank is displayed in real time by the water level indicator light to help the staff understand the water level in the water tank.

[0021] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS
