Overhead platform floor drain device

Abstract

The utility model provides an elevated platform floor drain device. The problem that an existing elevated platform floor drain is prone to icing in winter is solved. The filter screen arranged on the mounting plate is used for filtering impurities such as leaves, water flow is conveyed to the upper end of the electric heating pipe after passing through the guide ring, and the water flow is always in contact with the electric heating pipe when being discharged downwards in the shell through the spirally arranged guide plate, so that the path of the water flow is further prolonged, and the water flow is more uniform. When the water flow is too large, the displacement of a path defined by the guide plates is insufficient, the water flow upwards overflows through the drainage groove, and the low-temperature water flow and the heated water flow on the guide plates are converged at the lower end of the shell, so that the water flow can be effectively heated, and the water flow is prevented from being condensed into ice; and a certain temperature is ensured to avoid icing.

Description

Technical Field

[0001] This utility model relates to the field of floor drain technology, and in particular to a floor drain device for elevated platforms. Background Technology

[0002] Considering factors such as construction costs and location, some platforms are located on elevated structures. In winter, when the average daily temperature remains between 5-15℃, the elevated platforms experience high wind speeds and significant diurnal temperature variations. The surface temperature of the drains may drop below 0℃, causing water to easily freeze at the traps or drain outlets, forming icicles or ice layers, leading to drainage stagnation. Furthermore, at drain outlets located below the elevated structure, icicles easily form, which can fall to the ground and injure pedestrians or vehicles, requiring manual removal from the elevated area. Additionally, fallen leaves, mud, and other debris entering the drains mix with the ice layer at low temperatures, forming blockages that are even more difficult to remove. Therefore, the existing technology has room for improvement. Summary of the Invention

[0003] This utility model addresses the aforementioned shortcomings by providing a floor drain device for elevated platforms. It includes a mounting plate installed at the drain outlet on the elevated platform. A housing, for insertion into a drain channel and extending downwards, is fixedly mounted on the lower end of the mounting plate. A certain gap is left between the outer wall of the housing and the drain channel. A guide ring for guiding water flow is fixedly mounted on the lower end of the mounting plate. The upper end of the housing is fixedly mounted on the outer wall of the guide ring, and the diameter of the guide ring gradually decreases from top to bottom. A filter screen for filtering debris is provided on the mounting plate. The housing is fixed with… An electric heating element for heating the water flow is provided, located directly below the guide ring. A guide plate for guiding the water flow inside the housing is provided between the outer wall of the electric heating element and the inner wall of the housing. The guide plate extends downward in a spiral shape around the outer circumference of the electric heating element. Several drainage grooves communicating with the inside of the housing are provided on the outer wall of the upper end of the housing. The electric heating element is powered by an external power supply device through a connecting wire. A water level sensor for detecting the water level inside the housing is fixedly installed on the inner wall of the housing, located below the drainage grooves.

[0004] Preferably, the drainage grooves extend vertically and are evenly distributed along the outer periphery of the shell.

[0005] Preferably, the filter screen includes a first filter layer, a second filter layer, and a third filter layer arranged sequentially from the outside to the inside. The heights of the first filter layer, the second filter layer, and the third filter layer decrease sequentially. A first transition portion is provided between the first filter layer and the second filter layer, and a second transition portion is provided between the second filter layer and the third filter layer. A plurality of first filter grooves are provided on the first filter layer and the center of the third filter layer is located along the length direction of the first filter groove. A plurality of second filter grooves are provided on the third filter layer, and the second filter grooves are arc-shaped.

[0006] Preferably, an upwardly extending support plate is fixedly provided on the outer periphery of the upper end of the mounting plate. The support plate is rectangular, and a downwardly extending top plate that cooperates with the support plate is fixedly provided on the lower end of the outer periphery of the first filter layer. The top plate is attached to the inner wall of the support plate, and the height of the top plate is greater than the height of the first transition portion.

[0007] Preferably, the second transition portion is provided with a plurality of third filter grooves extending in a vertical direction, and the third filter grooves are evenly distributed around the center of the second transition portion.

[0008] Preferably, a handle for easy gripping is fixedly provided on the first filter layer.

[0009] Preferably, the diameter of the electric heating tube is larger than the diameter of the lower end of the guide ring.

[0010] Compared with existing technologies, this utility model filters out debris such as leaves through a filter screen installed on the mounting plate. The water flow is delivered to the upper end of the electric heating tube after passing through the guide ring. The spirally arranged guide plate ensures that the water flow is always in contact with the electric heating tube as it flows downwards inside the shell, further extending the water flow path and increasing the contact time between the water flow and the electric heating tube. This effectively heats the low-temperature water flow and prevents the water from condensing into ice after discharge. When the water flow is too large, the flow rate of the path formed by the guide plate is insufficient, and the water flows upwards and overflows through the drain channel. The low-temperature water flow and the water flow heated on the guide plate merge at the lower end of the shell, ensuring a certain temperature and preventing freezing. Attached Figure Description

[0017] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0018] like Figure 1-5 As shown, an elevated platform floor drain device includes a mounting plate 1 installed at the drain outlet on the elevated platform. A housing 2, for insertion into a drain channel and extending downwards, is fixedly mounted on the lower end of the mounting plate 1. A certain gap is left between the outer wall of the housing 2 and the drain channel. A guide ring 3 for guiding water flow is fixedly mounted on the lower end of the mounting plate 1. The upper end of the housing 2 is fixedly mounted on the outer wall of the guide ring 3, and the diameter of the guide ring 3 gradually decreases from top to bottom. A filter screen 4 for filtering debris is provided on the mounting plate 1. An electric heating tube 5 for heating the water flow is fixedly mounted inside the housing 2. The electric heating tube 5 is located directly below the guide ring 3, and its diameter is larger than the diameter of the lower end of the guide ring 3. A gap is provided between the outer wall of the electric heating tube 5 and the inner wall of the housing 2 to support the water flow. A guide plate 6 guides the internal water flow, extending downwards in a spiral shape around the outer periphery of the electric heating tube 5. Several drainage channels 7 connected to the inside of the housing 2 are provided on the outer wall of the upper end of the housing 2. The drainage channels 7 extend vertically and are evenly distributed along the outer periphery of the housing 2. The electric heating tube 5 is powered by an external power supply device via a connecting line 8. The power supply device is a solar panel and an energy storage device. During spring, summer and autumn, the connection to the electric heating tube 5 is disconnected and it does not work. In winter, when the temperature is low, the power supply device and the electric heating tube 5 are reconnected. During the day, energy is stored through the solar panel, and at night, the energy storage device powers the electric heating tube 5, effectively reducing the overall power consumption. A water level sensor 9 for detecting the water level inside the housing 2 is fixedly installed on the inner wall of the housing 2. The water level sensor 9 is located below the drainage channels 7. Debris such as leaves are filtered through the filter screen 4 set on the mounting plate 1. After the water flows through the guide ring 3, it is delivered to the upper end of the electric heating tube 5. The spiral guide plate 6 ensures that the water always contacts the electric heating tube 5 as it flows downward in the housing 2, further extending the water flow path and increasing the contact time between the water flow and the electric heating tube 5. This effectively heats the low-temperature water flow and prevents the water from freezing into ice after it is discharged. By extending the heating time per unit water flow, the power consumption of the motor heat pipe can be effectively reduced, enabling precise temperature control. When the water flow is too large, the drainage capacity of the channel formed by the guide plate 6 is insufficient, and the water flows upward through the drain trough 7. Or, when the temperature is too low and the inside freezes, the water flow contacts the water level sensor 9, triggering an alarm on the external platform to remind the staff and allow for timely handling. Manual inspection is required to check whether the overflow is caused by debris blockage. The low-temperature water flow and the water flow heated on the guide plate 6 converge at the lower end of the housing 2 to ensure a certain temperature and prevent freezing.

[0019] The filter screen 4 includes a first filter layer 10, a second filter layer 11, and a third filter layer 12 arranged sequentially from the outside to the inside. The heights of the first filter layer 10, the second filter layer 11, and the third filter layer 12 decrease sequentially. The third filter layer 12 is located inside the guide ring 3. A first transition portion 13 is provided between the first filter layer 10 and the second filter layer 11, and a second transition portion 14 is provided between the second filter layer 11 and the third filter layer 12. A plurality of first filter grooves 15 are provided on the first filter layer 10 and the second filter layer 11. The center of the third filter layer 12 is located in the length direction of the first filter groove. A plurality of second filter grooves 16 are formed on the third filter layer 12. The second filter grooves 16 are arc-shaped. An upwardly extending support plate 17 is fixedly disposed on the outer periphery of the upper end of the mounting plate 1. The support plate 17 is rectangular. A downwardly extending top plate 18 is fixedly disposed on the lower end of the outer periphery of the first filter layer 10, which cooperates with the support plate 17. The top plate 18 is attached to the inner wall of the support plate 17, and the height of the top plate 18 is greater than the height of the first transition portion 13. A plurality of third filter grooves 19 extending vertically are disposed on the second transition portion 14. The third filter grooves 19 are evenly distributed around the center of the second transition portion 14. A handle 20 for easy gripping is fixedly disposed on the first filter layer 10. After installation, the first filter layer 10 is mounted on the mounting plate 1 via the outer top plate 18. The top plate 18 is attached to the inner wall of the support plate 17, leaving a certain gap between the first filter layer 10 and the second filter layer 11 and the mounting plate 1. During water filtration, water flows into the area above the mounting plate 1 from the first filter groove 15 on the first filter layer 10 and the second filter layer 11, and flows into the guide ring 3 through the gap between the first filter layer 10 and the second filter layer 11 and the mounting plate 1. Fallen leaves and large particles mixed with the water flow are washed along the first filter layer 10, the second filter layer 11 and the third filter layer 11 by the water flow. Layer 12 moves and accumulates above the deeper third filter layer 12. Through the first filter layer 10, the second filter layer 11, and the third filter layer 12, which have height differences from each other, the debris on the filter screen accumulates layer by layer. With multiple layers, the debris accumulates at a certain angle, allowing water to flow through. This effectively prevents the filter screen from being completely blocked by debris. The accumulated debris can be cleaned by manual periodic inspection. Furthermore, through the elongated first filter tank 15 and the arc-shaped second filter tank 16, large particles of debris and fallen leaves cannot pass through the filter screen 4, making it less likely to clog the pipes.

[0020] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications to the specification derived therefrom are still within the protection scope of this utility model.
