Description

Technical Field

[0001] This utility model relates to the field of wastewater recycling technology, and in particular to a wastewater recycling device for green service areas along highways. Background Technology

[0002] Highway service areas generate large amounts of wastewater daily, such as catering wastewater, car wash wastewater, and toilet wastewater. If this wastewater is discharged directly without recycling or treatment, it not only wastes a significant amount of water resources but also potentially pollutes the surrounding environment. Therefore, wastewater recycling is essential. Highway service areas are typically located in remote areas, far from centralized sewage treatment facilities in cities. Containerized wastewater recycling systems, due to their mobility and ease of installation, are well-suited to the geographical characteristics of service areas, allowing for the rapid establishment of a wastewater recycling system without large-scale infrastructure projects.

[0003] Existing containerized wastewater recycling systems, such as the Chinese patent with publication number CN118005205A, utilize solar photovoltaic panels to achieve green power generation and energy conservation. However, the position of the solar photovoltaic panels on the top of the container is fixed at the factory and pre-set. The orientation and tilt angle of the solar photovoltaic panels significantly affect their solar energy capture efficiency. Different regions require different angles and orientations to obtain the longest sunshine hours and maximize solar energy capture. However, highway service areas have diverse terrain layouts and different pipeline systems. The placement of the container needs to consider sufficient layout space and convenient pipeline connections, resulting in the solar photovoltaic panels on the top of the container not having the optimal orientation and tilt angle, thus reducing the overall energy efficiency of the system. Utility Model Content

[0004] In view of this, this utility model proposes a wastewater recycling device for green service areas on highways, with the aim of improving the ease of adjustment of solar photovoltaic panels on existing containerized wastewater recycling systems.

[0005] The solution provided by this utility model includes:

[0006] A wastewater recycling device for a highway green service area includes a container, a water purification unit installed inside the container, and a solar photovoltaic panel installed on the top of the container. The top of the container is equipped with an orientation adjustment mechanism and a telescopic support rod.

[0007] The orientation adjustment mechanism includes a turntable and a fixing assembly. The turntable is rotatably mounted on the top of the container about a vertical axis, and the fixing assembly is used to fix the turntable relative to the container.

[0008] The solar photovoltaic panel is mounted on the turntable, and one side of it is hinged to the turntable;

[0009] The telescopic support rod is mounted on the turntable, with one end hinged to the turntable and the other end hinged to the back of the solar photovoltaic panel.

[0010] As a further optional solution, the fixing component includes a fixing bracket and a pin. The fixing bracket is fixedly installed on the container. The fixing bracket is provided with a sleeve hole. The turntable is provided with a plurality of positioning holes arranged equidistantly along the circumference. The pin passes through the sleeve hole and one of the positioning holes to fix the turntable.

[0011] As a further optional feature, the orientation adjustment mechanism also includes a mounting base, which is fixedly mounted on the top of the container, and the turntable is rotatably connected to the mounting base.

[0012] As a further alternative, the pin is a bolt, and the pin is threadedly connected to the sleeve hole.

[0013] As a further optional solution, the water purification unit includes, in sequence according to the pipeline connection order, a sedimentation tank, a cyclone separator, a security filter, a dosing device, a reverse osmosis membrane device, and a water storage tank.

[0014] The container is equipped with a water inlet and a water outlet. The water inlet is connected to the sedimentation tank, and the water outlet is connected to the water storage tank.

[0016] As a further optional solution, the container is equipped with an energy storage device, which is electrically connected to the solar photovoltaic panel.

[0017] Compared with existing technologies, the wastewater recycling device for highway green service areas proposed in this application has at least the following advantages:

[0018] The wastewater recycling device in the highway green service area can adjust the orientation of the solar photovoltaic panels through an orientation adjustment mechanism. By adjusting the length of the telescopic support rod, the tilt angle of the solar photovoltaic panels can be adjusted.

[0028] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0029] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0032] refer to Figure 1-4 This utility model discloses a wastewater recycling device for a highway green service area, including a container 1, a water purification unit 2 installed inside the container 1, and a solar photovoltaic panel 3 installed on the top of the container 1. The top of the container 1 is provided with an orientation adjustment mechanism 4 and a telescopic support rod 5. The orientation adjustment mechanism 4 includes a turntable 41 and a fixing component 42. The turntable 41 is rotatably installed on the top of the container 1 about a vertical axis, and the fixing component 42 is used to fix the turntable 41 relative to the container 1. The solar photovoltaic panel 3 is installed on the turntable 41, and one side of it is hinged to the turntable 41. The telescopic support rod 5 is installed on the turntable 41, with one end hinged to the turntable 41 and the other end hinged to the back of the solar photovoltaic panel 3.

[0033] Specifically, the container 1, water purification unit 2, and solar photovoltaic panel 3 mentioned above can all be prefabricated and assembled in the factory. After the wastewater recycling device is transported to the highway service area, a suitable location is selected for placement according to the on-site installation conditions. After the placement location of container 1 is determined, the orientation adjustment mechanism 4 and telescopic support rod 5 are used to adjust the orientation and tilt angle of solar photovoltaic panel 3 respectively.

[0034] Generally, if the highway service area is located in the Northern Hemisphere, the solar photovoltaic panel 3 should face due south; if it is located in the Southern Hemisphere, it should face due north to maximize sunshine duration. Furthermore, the tilt angle of the solar photovoltaic panel 3 is determined based on the latitude of the highway service area's location.

[0035] During adjustment, first rotate turntable 41 to rotate solar photovoltaic panel 3 to a suitable orientation. Then, fix turntable 41 using fixing component 42 to fix the orientation of solar photovoltaic panel 3. After determining the orientation, adjust the length of telescopic support rod 5 to change the tilt angle of solar photovoltaic panel 3, so that its tilt angle is closer to the optimal theoretical value. In this way, regardless of the terrain layout, pipeline system, or installation position of container 1 within the highway service area, the solar photovoltaic panel 3 on top of container 1 can be adjusted to the optimal orientation and angle to improve the power supply efficiency of the wastewater recycling device in the highway green service area.

[0036] In some embodiments, to further improve the ease of adjusting the orientation of the solar photovoltaic panel 3, such as Figure 3 and Figure 4 As shown, the fixing component 42 includes a fixing bracket 421 and a pin 422. The fixing bracket 421 is fixedly installed on the container 1. The fixing bracket 421 is provided with a sleeve hole 4211. The turntable 41 is provided with a plurality of positioning holes 411 arranged equidistantly along the circumference. The pin 422 passes through the sleeve hole 4211 and one of the positioning holes 411 to fix the turntable 41. The fixing bracket 421 is fixed to the top of the container 1 by welding or bolting.

[0037] When it is necessary to adjust the orientation of the solar photovoltaic panel 3, simply pull out the pin 422, then rotate the turntable 41. Once the circumferential rotation angle of the turntable 41 is determined, align the positioning hole 411 on the turntable 41 with the sleeve hole 4211 vertically, and then reinsert the pin 422 to fix the turntable 41. This operation is quick and simple.

[0038] In another embodiment, from a stability perspective, the pin 422 is a bolt, and the pin 422 is threadedly connected to the sleeve hole 4211. This makes it less likely for the pin 422 to accidentally disengage from the sleeve hole 4211 and the positioning hole 411 on the turntable 41, thus improving the stability of the turntable 41.

[0039] In the above scheme, such as Figure 3 As shown, the orientation adjustment mechanism 4 also includes a mounting base 43, which is fixedly mounted on the top of the container 1. The turntable 41 is rotatably connected to the mounting base 43. The mounting base 43 is fixed to the top of the container 1 by welding or bolting.

[0040] In some embodiments, to facilitate personnel climbing onto the top of the container 1 to adjust the orientation and tilt angle of the solar photovoltaic panels 3, such as... Figure 1 and Figure 2 As shown, a ladder 13 is provided on the outside of the container 1.

[0041] In the above scheme, such as Figure 1 As shown, the container 1 is equipped with an energy storage device 31, which is electrically connected to the solar photovoltaic panel 3. Thus, the energy storage device 31 stores the electrical energy converted by the solar photovoltaic panel 3 to power the power-consuming components in the water purification unit 2.

[0042] It should be noted that the water purification unit 2 can be customized according to actual water purification needs, such as the water purification unit 2 in publication number CN118005205A.

[0043] like Figure 1 As shown, this embodiment provides a water purification unit 2, which includes a sedimentation tank 21, a cyclone sand separator 22, a security filter 23, a dosing device 24, a reverse osmosis membrane device 25, and a water storage tank 26 in sequence according to the pipe connection order.

[0044] Wastewater is transported to sedimentation tank 21 via pipeline. Sedimentation tank 21 is made of corrosion-resistant material and includes an inlet and overflow weir. A conical sludge hopper and an electric sludge discharge valve are located at the bottom. Wastewater remains in the tank for 0.5-2 hours, where large suspended solids (such as silt and algae) are separated by gravity sedimentation. Bottom sediment is periodically discharged through the sludge discharge valve to prevent putrefaction and water quality deterioration. Sedimentation tank 21 provides primary filtration.

[0045] After primary sedimentation in sedimentation tank 21, the wastewater is pressurized and transported by pump to cyclone separator 22. Under the action of centrifugal force, sand particles with a density greater than water sink to the bottom sand collection hopper, and clean water is discharged from the top overflow port.

[0046] The water from the cyclone separator 22 enters the security filter through the pipeline, where it traps suspended solids, colloids and other residual particles, ensuring that the subsequent reverse osmosis membrane is not physically fouled.

[0047] A dosing device 24 is connected in parallel to the outlet of the security filter. Chemicals, such as organic phosphonates or polyacrylic acid compounds, are added through the dosing device 24. The chemicals inhibit the crystallization of calcium and magnesium ions in the wastewater through chelation, prevent scaling on the surface of the reverse osmosis membrane, and improve membrane flux and desalination rate.

[0048] The wastewater is then pressurized by a high-pressure pump and fed into the reverse osmosis membrane device 25 for filtration. The resulting purified water is then fed into the storage tank 26.

[0049] In the above scheme, such as Figure 2As shown, the container 1 is equipped with a water inlet 11 and a water outlet 12. The water inlet 11 is connected to the sedimentation tank 21, and the water outlet 12 is connected to the water storage tank 26. The water inlet 11 is used to receive wastewater from the highway service area, while the water outlet 12 can discharge purified water from the water storage tank 26. This purified water can be used for greening irrigation, toilet flushing, road cleaning, etc.

[0050] In summary, this application provides a wastewater recycling device for highway green service areas. This device can adjust the orientation of the solar photovoltaic panel 3 through the orientation adjustment mechanism 4, and adjust the tilt angle of the solar photovoltaic panel 3 by adjusting the length of the telescopic support rod 5. Therefore, regardless of the terrain layout, pipeline system, or installation position of the container 1 within the highway service area, the solar photovoltaic panel 3 on the top of the container 1 can be adjusted to the optimal orientation and angle to improve the power supply efficiency of the wastewater recycling device for highway green service areas.

[0051] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0052] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
