Description

Technical Field

[0001] This utility model relates to a standardized stall device that can supply its own energy and process its own waste. Background Technology

[0002] Currently, the street vendor economy, including vegetable markets and night markets, not only promotes consumer spending and drives economic growth but also expands urban living scenarios. With the continuous development of urbanization in my country, the "street vendor economy" is increasingly active in every corner of the city, becoming a popular new urban business model. However, the lack of scientific planning and guidance has led to a series of problems with urban stalls: First, they fail to utilize urban land resources efficiently and intensively. For example, daytime vegetable stalls and night markets are not fully integrated, with each only used during the day or night, resulting in low space utilization. Second, they impact the urban environment and public health. Daily sales activities inevitably generate a large amount of garbage, polluting the environment. Stalls selling fresh food often produce large amounts of organic food waste such as animal offal, rotten vegetable leaves, and expired food. If not handled promptly, this waste produces unpleasant odors, breeds bacteria, and causes inconvenience to nearby residents. Third, they pose safety hazards and are difficult to manage. For example, individual vendors frequently engage in dangerous behaviors such as illegally wiring electrical wires, discharging wastewater, and occupying roads, making standardized and safe management impossible.

[0003] In summary, existing urban stalls suffer from environmental pollution, chaotic management, and low space utilization. These issues make the management of the "street vendor economy" a crucial test of urban governance. Therefore, there is a need for a compact, flexible, environmentally friendly, energy-saving, and self-supplied, waste-processing standardized stall device that can be assembled and combined according to different terrain conditions. This device would protect the "street vendor economy" while addressing a series of issues related to space, environment, and safety. This case study was developed to address these problems.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] (1) This utility model has a simple structure, reasonable design, and convenient use. It can solve the problems of environmental pollution, chaotic management, and low space utilization that are difficult to solve in existing urban stalls. By placing the corresponding stalls under the standardized stall device, the photovoltaic panels of the photovoltaic power generation and energy storage system are used to charge the storage battery with solar energy. The storage battery is used to power the lamp tubes, the garbage disposal system, and the stall. When processing the garbage generated by the stall, the garbage is fed into the crushing module through the garbage collection hopper of the preliminary treatment device of the garbage disposal system. The crushing spiral blades of the crushing module rotate to crush the garbage into a mixed paste. After crushing, the valve A at the output end of the crushing cylinder of the crushing module is opened, and the mixed paste garbage enters the extrusion drying module. The valve A at the inlet and outlet of the folding cylinder of the extrusion drying module is closed. The cylinder of the extrusion drying module drives the folding cylinder to compress, and the liquid of the mixed paste is discharged into the oil-water separation device through the liquid outlet of the folding cylinder, while the water is squeezed dry. The remaining solid waste is dried by heating with a heater. Then, valve A at the discharge port of the folded cylinder is opened, and the dried solid waste is fed into the solid fermentation device. The fermentation tank of the solid fermentation device contains fermentation bacteria, which can ferment the solid waste to form ecological fertilizer for recycling. The positive and negative electrolytic rods of the oil-water separation device electrolyze the mixed liquid, causing small oil droplets to aggregate into larger oil droplets, thus separating the oil-water mixture into large oil molecules and small water molecules. Valve B of the water outlet pipe is opened. Since there is a filter membrane at the inlet of the water outlet pipe, only small water molecules can pass through the filter membrane and enter the water storage module. The remaining liquid is pure oil. The pure oil enters the oil storage module through the oil outlet pipe. After subsequent sedimentation, it can be recycled to form biodiesel. When it rains, the rainwater is discharged directly into the water storage module through the photovoltaic rainwater collection port of the photovoltaic power generation and energy storage system, the support frame rainwater collection port of the umbrella-shaped support frame, and the rainwater collection pipe.

[0017] (2) This utility model solves the problem of environmental pollution caused by the failure to dispose of garbage in a timely manner by setting up a garbage disposal system; it solves the safety hazards of privately connected wires that are common in the current market by setting up an umbrella-shaped support system for the circuit pipes, and hides the power lines inside the circuit pipes. This protects the environment and beautifies the city while promoting consumption in the "street vendor economy". At the same time, the garbage disposal system is used to dispose of waste garbage and the photovoltaic panels of the umbrella-shaped support system convert solar energy into electrical energy to promote resource recycling and turn waste into treasure. The individual standardized stall device is small and flexible, easy to disassemble and move, and can be spliced ​​together to be spliced ​​into different shapes according to the characteristics of different sites. It can be used in scattered, corner and idle open space resources in the city, making full use of land resources while getting closer to residents' lives. Attached Figure Description

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0033] Example 1: Refer to Appendix Figure 1-14 As shown, a standardized stall device that can supply its own energy and process its own waste is provided, including an umbrella-shaped support system 2, a photovoltaic power generation and energy storage system 1 and a waste processing system 3 respectively installed at the top and bottom of the umbrella-shaped support system.

[0034] In this embodiment of the utility model, the umbrella-shaped support system 2 includes an umbrella-shaped support frame 201 and a support member 202 disposed below the umbrella-shaped support frame. The umbrella-shaped support frame supports the photovoltaic panel, and the support member supports the umbrella-shaped support frame. The lower part of the support member is connected to the shell. The support member is internally provided with an electrical conduit 203 and a rainwater collection conduit 204. The electrical conduit is used to run a protective power line, and the rainwater collection conduit is used to collect rainwater. The umbrella-shaped support frame is provided with a rainwater collection port 205 in the middle. One end of the outlet is connected to a rainwater collection pipe, and the other end of the rainwater collection pipe is connected to a water storage module of the waste treatment system. Multiple curved support plates 206 are provided between the umbrella-shaped support frame and the support member. The curved support plates and the support member are connected by connectors 207. A lamp tube (not shown in the figure) is installed on each curved support plate. An annular steel plate 208 is provided between adjacent curved support plates. A storage battery 103 is installed on the inner side of the annular steel plate. The storage battery is electrically connected to the photovoltaic power generation and energy storage system, the lamp tube, and the waste treatment system.

[0035] The curved support plate described above is hollow inside, and an opening can be set at its bottom to insert a lamp tube for lighting. Of course, the curved support plate can also be made transparent for easy lighting.

[0036] The aforementioned circuit can be equipped with three power lines. One end of each power line is connected to a storage battery, and the other end is connected to a light switch, a power connector for stall users, and a waste disposal system, respectively.

[0037] The aforementioned umbrella-shaped support frame 201 includes a polygonal umbrella body 2011 and an umbrella cloth set on the polygonal umbrella body. Of course, it is also possible to omit the umbrella cloth and use a sealed and spliced ​​photovoltaic polygonal body to form a stall top cover to cover the stall. The polygonal umbrella body is spliced ​​together from multiple fixed steel pipes 2012. Supporting steel pipes 2013 are provided between the connection of adjacent fixed steel pipes and the annular steel plate. The supporting steel pipes and the curved support plate are staggered. The annular steel plate plays a reinforcing role.

[0038] The aforementioned polygonal umbrella body can be a dodecagonal body that curves upward and opens. The edge of the dodecagonal body is formed by splicing together twelve fixed steel pipes. The edge of the dodecagonal body has six inner angles and six outer angles, which are staggered. A curved support plate is set between the inner angles and the support member, and a support steel pipe is installed between the outer angle and the annular steel plate.

[0039] In this embodiment of the utility model, the photovoltaic power generation and energy storage system 1 includes a photovoltaic polygonal body composed of six photovoltaic panels 101 spliced ​​together. A photovoltaic rainwater collection port 102 is provided in the middle of the photovoltaic polygonal body. The photovoltaic rainwater collection port 102 is connected to the rainwater collection port 205 of the support frame. The upper surface of the photovoltaic polygonal body is inclined towards the photovoltaic rainwater collection port in the middle. Each photovoltaic panel is adapted to a battery 103 set on the umbrella-shaped support frame. The battery is electrically connected to the photovoltaic panel. Under normal circumstances, the electrical energy generated by the photovoltaic panel is uniformly collected into the battery, which can meet the power consumption of the battery. Photovoltaic power generation and power storage are existing technologies and will not be described in detail here. Of course, in order to avoid unexpected situations and ensure the battery power, the battery can also be directly charged by an external power source.

[0040] The outer side of each photovoltaic panel is tilted upwards at 5° along the inner side of the photovoltaic panel, making the overall shape of the photovoltaic polygon resemble a funnel. This can collect and utilize rainwater during rain, avoiding drainage problems caused by sudden heavy rain.

[0041] In this embodiment of the utility model, the waste treatment system 3 includes a shell 37 and a preliminary treatment device 31, a solid fermentation device 32, an oil-water separation device 33, an oil storage module 34, and a water storage module 35 disposed within the shell. After being treated by the preliminary treatment device, the solid fermentation device, and the oil-water separation device, the waste is respectively formed into waste fermentation material, oil, and water.

[0042] The bottom of the housing is equipped with casters 36 for easy movement.

[0043] In this embodiment of the present invention, the preliminary processing device 31 includes a garbage collection hopper 311, a crushing module 312, and an extrusion drying module 313 arranged sequentially along the garbage conveying direction; the garbage collection hopper extends outward from the surface of the shell, the inlet end of the garbage collection hopper is a garbage collection port 314, and the outlet end of the garbage collection hopper is connected to the crushing module; the crushing module 312 includes a crushing cylinder 3121 and crushing spiral blades 3122 disposed inside the crushing cylinder, the crushing spiral blades being driven to rotate by a crushing motor; the extrusion drying module 313 includes a folded cylinder 31 disposed below the crushing cylinder 3121. 31. The feed inlet of the folding cylinder is connected to the discharge outlet of the crushing cylinder. The folding cylinder is driven to fold or unfold by a cylinder 3132 installed on the crushing cylinder to squeeze the crushed waste and achieve solid-liquid separation. The output end of the cylinder is connected to the lower outer side of the folding cylinder via a mechanical arm 3133. The upper part of the folding cylinder is fixed on the crushing cylinder. The cylinder pulls the folding cylinder to contract and squeeze the mixed paste-like waste inside, thereby squeezing out the water and discharging it out through the liquid outlet of the folding cylinder. Solid waste with squeezed water is left in the folding cylinder. After drying and baking, the solid waste is fed into the fermentation cylinder for fermentation.

[0044] Valves A are installed at the feed inlet at the top and the discharge outlet at the bottom of the folded cylinder. Valves A can be solenoid valves. A filter screen 3135 is installed inside the folded cylinder. The filter screen is made of elastic material and can be elastically folded and deformed. It can spring back to its original position when no force is applied. The filter screen has multiple filter holes. The filter screen is used to divide the inner part of the folded cylinder into an inner layer 3137 and an outer layer 3138. The squeezed water flows through the filter screen to the outer layer of the folded cylinder and then flows out through the liquid outlet. A liquid outlet is provided on the side of the outer layer of the folded cylinder. The liquid outlet is connected to the oil-water separation device through a liquid outlet pipe 3134. A ring-shaped heater (not shown in the figure) is also installed at the bottom of the folded cylinder. The heater is existing technology. The heater can be in the form of resistance wire heating or electric heating rod heating. It heats and dries the remaining solid after extrusion by generating heat. Of course, the heater can also be other existing drying equipment, such as a dryer that introduces hot air.

[0045] When the crushing module is working, valve A above the folding cylinder is closed; after the crushing module finishes working, valve A above the folding cylinder opens, allowing the crushed waste to enter the folding cylinder. At this time, valves A at the feed inlet and discharge outlet of the folding cylinder are closed. The liquid of the paste-like waste inside the folding cylinder is squeezed out by the contraction and folding of the folding cylinder.

[0046] In this embodiment of the present invention, the input end of the solid fermentation device 32 is connected to the output end of the folded cylinder of the extrusion drying module of the preliminary treatment device; the solid fermentation device includes a plurality of fermentation tanks 321 containing fermentation bacteria, the fermentation tanks penetrate the shell, and each fermentation tank is fixed to the shell by a ring-shaped mechanical arm 322.

[0047] The fermentation tank is equipped with a lid, which makes it easy to remove the fermented organic fertilizer. A timer can be installed on the outside of the fermentation tank. The timer is an existing technology and can be a timer.

[0048] In this embodiment of the utility model, the oil-water separation device 33 includes an oil-water separation cylinder 331 and positive and negative electrolytic rods 332 disposed inside the oil-water separation cylinder. The oil-water separation cylinder is respectively connected to a water outlet pipe 333 and an oil outlet pipe 334. The input ends of the water outlet pipe and the oil outlet pipe are both equipped with valves B, which can be solenoid valves. The input end of the water outlet pipe is equipped with a filter membrane, which only allows small water molecules to pass through, and the remaining liquid is pure oil. The output end of the water outlet pipe is connected to a water storage module, the input end of the oil outlet pipe is connected to the oil-water separation cylinder, and the output end of the oil outlet pipe is connected to an oil storage module.

[0049] When the positive and negative electrolytic rods electrolyze the mixed liquid, small oil droplets aggregate into larger oil droplets, thus separating the oil-water mixture into large oil molecules and small water molecules. When valve B of the water outlet pipe is opened, since there is a filter membrane at the inlet of the water outlet pipe, only small water molecules can pass through the filter membrane and enter the water storage module; the remaining liquid is pure oil. After the water molecules have been discharged, valve B of the oil outlet pipe is opened to discharge the pure oil into the oil storage module.

[0050] The oil-water separation principle of the oil-water separation device is as follows: By utilizing the principle of electrolysis, bubbles are generated, causing small oil droplets to aggregate into larger oil droplets. Oil and water are separated by passing through filter screens with different pore sizes. A combined cathode and anode method is used. The chemical equation for the cathode is 2H2O+2e-==H2+2OH-, which releases hydrogen gas. The chemical equation for the anode is 4OH-==O2+2H2O+4e-, which releases oxygen gas.

[0051] After the oil and water are electrolyzed by the positive and negative electrode electrolysis rods, valve B of the water outlet pipe is opened. The filter membrane of the water outlet pipe only allows small water molecules to pass through, while the remaining liquid is pure oil. The pure oil is output to the oil storage module through the oil outlet pipe. The collected pure oil can be recycled and reused. For example, the pure oil can be precipitated to form biodiesel for use.

[0052] The water storage module 35 is provided with a water outlet, which makes it convenient to extract the water in the water storage module for reuse, such as for cleaning the stall, thus saving water resources; the oil storage module 34 is provided with an oil outlet, and both the water outlet and the oil outlet are provided with hoses 371, which makes it convenient to extract pure oil from the oil storage module for reuse.

[0053] In this embodiment of the utility model, when in use: (1) the corresponding stalls are placed under the standardized stall device; (2) the photovoltaic panels of the photovoltaic power generation and energy storage system are used to charge the storage battery with solar energy, and the storage battery is used to power the lamp tubes, the waste treatment system and the stalls; (3) when processing the waste generated by the stalls, the waste is fed into the crushing module through the waste collection bucket of the preliminary treatment device of the waste treatment system. The crushing spiral blades of the crushing module rotate to crush the waste into a mixed paste. After crushing, the valve A at the output end of the crushing cylinder of the crushing module is opened, and the mixed paste waste enters the extrusion drying module; (4) the valve A at the inlet and outlet of the folding cylinder of the extrusion drying module is closed. The cylinder of the extrusion drying module drives the folding cylinder to compress, and the liquid of the mixed paste is discharged into the oil-water separation device through the liquid outlet of the folding cylinder. The remaining solid waste after squeezing out the water is heated and dried by the heater, and then folded Valve A at the discharge port of the stacked cylinder is opened, and the dried solid waste is input into the solid fermentation device. The fermentation tank of the solid fermentation device is equipped with fermentation bacteria, which can ferment the solid waste to form ecological fertilizer for recycling; (5) The positive and negative electrolysis rods of the oil-water separation device electrolyze the mixed liquid, causing small oil droplets to aggregate into larger oil droplets, thereby separating the oil-water mixed liquid into large oil molecules and small water molecules. Valve B of the water outlet pipe is opened. Since the water outlet pipe input end is equipped with a filter membrane, only small water molecules can pass through the filter membrane to enter the water storage module. The remaining liquid is pure oil. The pure oil enters the oil storage module through the oil outlet pipe. After subsequent sedimentation, it can be recycled to form biodiesel; (6) When it rains, the rainwater is directly discharged into the water storage module through the photovoltaic rainwater collection port of the photovoltaic power generation and energy storage system, the support frame rainwater collection port of the umbrella-shaped support frame, and the rainwater collection pipe.

[0054] Example 2: Based on Example 1, this utility model can be designed with different splicing schemes according to different terrains to suit different stall locations; such as... Figure 8 , 9 As shown, when located in the middle of a pedestrian street or in an open space between residential buildings, multiple individual standardized stalls can be pieced together in a straight line to facilitate shopping for pedestrians on both sides; for example... Figure 10 , 11 As shown, when multiple standardized stalls need to be arranged under a tree, the available space under the tree can be fully utilized by arranging them in a circular pattern; for example... Figure 12 , 13 As shown, when it is necessary to arrange stalls in triangular locations such as street corners, multiple standardized stall units can be joined together to form a triangular shape. The stalls within the aforementioned standardized stall units can be arranged according to the user's needs.

[0055] Example 3: Based on Example 2, in this embodiment of the present invention, a controller may be provided inside the housing. The controller is electrically connected to the crushing motor of the crushing module, the cylinder of the extrusion drying module, the heater, two valves A, the positive and negative electrolytic rods of the oil-water separation device, and two valves B.

By setting up an umbrella-shaped support system for the circuit pipes, it solves the safety hazards of privately connected wires that are common in current markets. The power lines are hidden inside the circuit pipes, which protects the environment and beautifies the city while promoting consumption in the "street stall economy". At the same time, by setting up a garbage disposal system and an umbrella-shaped support system for photovoltaic panels, it promotes the recycling of resources and turns garbage into treasure.

In addition, after the garbage pollution problem is solved, the daytime vegetable market and the night market can be integrated. By taking advantage of the staggered use time of the two, a multifunctional composite space with "one place for multiple uses" can be created, saving land resources and facilitating residents' lives. Through the utilization of various garbage resources, the urban commercial space can be transformed from an energy consumer to an energy producer, responding to the problem of insufficient resource and environmental carrying capacity in the process of rapid urban development and helping the city's green and low-carbon transformation.

After arriving at the site, they can be quickly assembled and formed. If the site needs to be changed, the position can be changed by changing the bottom pulley of a single standard stall device, and it can also be quickly disassembled and transported. No construction waste is generated during the assembly and disassembly process.
