Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of low-carbon energy-saving building equipment, and particularly relates to a low-carbon fabricated container machine room and a use method thereof. BACKGROUND

[0002] With the wide deployment of communication base stations, energy storage and control centers, emergency command stations and other facilities in various scenes, container machine rooms are widely used due to their compact structure, strong mobility and short installation period. The existing container machine rooms are usually composed of a steel box body, the outer wall of which is heat-insulated by using ordinary thermal insulation materials, and the interior is configured with air conditioning systems, power distribution systems and communication or control equipment to meet the environmental conditions required for equipment operation. However, under extreme weather conditions such as high temperature, low temperature, heavy rain and typhoon, the ordinary thermal insulation materials have a high thermal conductivity and limited heat insulation effect, resulting in a large internal air conditioning load and increased energy consumption. In addition, the sealing structure at the joint position of the box body is mostly fixed adhesive tape or simple sealing strips, which are prone to aging and deformation under the action of long-term wind and rain and thermal expansion and contraction, thereby causing water seepage in strong wind or heavy rain, affecting the safe operation of the equipment.

[0003] The existing machine rooms also have deficiencies in noise control. The communication, energy storage and other equipment will produce continuous noise when operating, and the traditional sound insulation method mostly uses single-layer sound insulation boards or foam materials, which have limited noise reduction effect and are prone to water absorption failure in humid environments, causing a decrease in sound insulation performance. At the same time, the problem of condensate water caused by temperature difference changes is common, and the accumulation of condensate water not only increases the humidity inside the machine room and causes corrosion of metal parts, but also may affect the insulation performance of electrical equipment.

[0004] In terms of energy utilization, most existing container machine rooms have a high dependence on external power grids and do not fully utilize renewable energy for self-generation and energy storage, resulting in a high carbon emission during operation. Although some machine rooms are equipped with photovoltaic power generation devices, the installation position and heat dissipation design are insufficient, and the efficiency of the photovoltaic panels decreases significantly under high temperature conditions. In addition, there is a lack of automatic cleaning system, and the accumulation of dust and stains will further reduce the power generation efficiency. Furthermore, the existing photovoltaic panel cleaning methods are mostly manual cleaning or fixed spraying, and the water flow coverage is limited, the flushing effect is not ideal, and the cleaning water mostly depends on external water supply, resulting in resource waste.

[0005] Therefore, the existing low-carbon fabricated container machine room still has deficiencies in terms of heat insulation performance, sealing and protection ability, noise reduction effect, condensate water utilization, renewable energy utilization efficiency, and photovoltaic cleaning and maintenance.

[0088] The working principle is that the photovoltaic panel 16 converts solar energy into electric energy, which is output to the energy storage battery pack through the MPPT controller to optimize the output, and the battery pack provides standby, lighting and peak-valley power adjustment power required for the machine room; when the battery power is sufficient and the surface temperature of the photovoltaic panel 16 exceeds 45℃, the cooling fan starts, and the air isolation chamber is forced to convect to reduce the temperature by 5-8℃, and the power generation efficiency of the photovoltaic panel 16 is improved by 3%-5%; the energy storage system charges in the low valley period and discharges in the peak period, reducing the dependence on the power grid by 40%.

[0089] The traditional photovoltaic panel of the machine room is directly installed on the roof without heat dissipation design, and the component temperature often reaches 65℃ at noon in summer, and the power generation efficiency decreases by more than 5%; the photovoltaic panel temperature of the embodiment is reduced by 8℃ under the same meteorological conditions, the annual power generation capacity is increased by about 4%, and the annual carbon reduction amount is 1.8 tons.

[0090] Embodiment 5:

[0091] Referring to Figures 1 to 7 A low-carbon assembled container machine room photovoltaic panel automatic cleaning system, comprising a dirt scraping mechanism 2, a reciprocating flushing mechanism 3, a condensate water tank 14 and a water pump 33. The dirt scraping mechanism 2 comprises a V-shaped block 21, a vertical plate 22, a fixed rod 23, a bolt rod 24, a sliding block 25, an extension block 26, an inclined surface 27, a moving plate 28, a scraping strip 218, an extension cylinder 29, a sliding rod 211, a butt joint cylinder 214, a swing plate 215, a roller 216, a limiting plate 210, a sliding groove 291, a fixed bolt 212, a spring 213, a fixed strip 4 and a through groove 41; the reciprocating flushing mechanism 3 comprises a bottom plate 31, a water collecting tank 32, a convex plate 34, a water pipe 35, a spray head 351, a gear 352, a bidirectional toothed plate 36, a mounting frame 321, a motor 37, a rotating disc 38, an eccentric bolt 381 and a connecting rod 39.

[0092] The working principle is that the condensate water tank 14 collects air conditioner condensate water, the water pump 33 pressurizes the water and sends it to the water collecting tank 32, and the photovoltaic panel 16 surface is sprayed and flushed with dust through the spray head 351; the motor 37 drives the eccentric bolt 381 and the connecting rod 39 to drive the bidirectional toothed plate 36 to move up and down, thereby driving the water pipe 35 to swing and expand the spraying coverage; the bolt rod 24 drives the sliding block 25 to move along the fixed rod 23, drives the moving plate 28 and the scraping strip 218 to reciprocate and remove stubborn stains; the sliding rod 211 and the spring 213 in the extension cylinder 29 ensure that the moving plate 28 maintains a forward inclination angle in both directions, and the roller 216 moves in the through groove 41 to ensure stable scraping trajectory.

[0093] The traditional photovoltaic panel cleaning relies on manual cleaning or fixed spraying, the coverage is limited and external water source is required, and the low cleaning frequency leads to a decrease of 3%-8% in power generation efficiency; the embodiment realizes full-automatic cleaning, uses condensate water recycling to save water by 120L / month, and keeps the power generation efficiency at a high level all year round.

[0094] Embodiment 6:

[0095] Referring to Figures 1 to 7 A low-carbon assembly type container machine room photovoltaic angle adjusting system, comprising a supporting mechanism, a photovoltaic panel 16, an angle adjusting mechanism and a sensing unit. The supporting mechanism is welded by galvanized rectangular pipes, and the surface is sprayed with epoxy zinc-rich paint to enhance corrosion resistance; the photovoltaic panel 16 is a single-crystal silicon component with a rated power of 450W. The angle adjusting mechanism is composed of an electric telescopic rod model LA36 with a thrust of 1500N and a stroke of 500mm and a rotating shaft hinge device, and the two ends of the telescopic rod are fixed to the bottom of the supporting mechanism and the back supporting arm of the photovoltaic panel 16, respectively, to ensure that the photovoltaic panel 16 can be adjusted within the range of 0-45°. The sensing unit includes a solar radiation intensity sensor with an accuracy of ±5%, a light angle measurement module, a weather monitoring module for wind speed, wind direction and rainfall, and a sensor signal input controller. The controller calculates the optimal inclination value and drives the telescopic rod to adjust the angle of the photovoltaic panel in combination with the date, time and weather conditions.

[0096] When the system detects the change of the solar altitude angle, the controller sends a signal to the electric telescopic rod, and the telescopic rod drives the photovoltaic panel 16 to adjust the angle step by step to ensure that the photovoltaic panel 16 always maintains the optimal incident angle. In strong wind or heavy rain weather, the weather sensor triggers the protection logic, and the photovoltaic panel 16 will automatically adjust to the horizontal position to reduce the wind area and prevent structural damage. Through this dynamic adjustment, the annual power generation efficiency of the photovoltaic component is improved by about 8%-12%.

[0097] The angle of the traditional fixed photovoltaic panel cannot be adjusted with the seasons, and the power generation efficiency decreases significantly at noon in summer, and the annual utilization rate is reduced; after the dynamic angle adjustment in this embodiment, the total annual power generation in the same area is increased by about 11%, and the risk of photovoltaic panel damage in severe weather is also reduced.

[0098] Example 7:

[0099] Referring to Figures 1 to 7 An intelligent operation and maintenance system of a low-carbon assembly type container machine room, comprising a fire extinguishing system 13, a condensate water tank 14, a supporting mechanism, a photovoltaic panel 16, a power distribution cabinet, an equipment control cabinet, a photovoltaic mains complementary device and an automatic control box. The core of the system is an intelligent control terminal using an ARM Cortex-A72 quad-core processor with a main frequency of 1.8GHz, and the terminal is connected with each functional module through Ethernet. The fire extinguishing system 13 is equipped with a smoke detector, a temperature detector and a dry powder extinguishing device; the condensate water tank 14 is connected with a water pump and a flushing system; the photovoltaic mains complementary device realizes dynamic switching of photovoltaic power generation and mains; the power distribution cabinet and the control cabinet are used for power supply for internal equipment such as fans, air conditioners and lighting and load protection; the automatic control box is built-in with a PLC module Siemens S7-1200 series for collecting various sensing signals and executing logic control.

[0100] The intelligent control terminal monitors the temperature, humidity, noise level, and power load in the box in real time through the centralized platform and automatically links the equipment operation. For example, when the temperature sensor detects that the temperature in the machine room exceeds 30℃, the intelligent terminal instructs the air conditioner and the fan to start; when the power generation power of the photovoltaic panel 16 is lower than the set value, the complementary device automatically switches to the mains power supply; if the smoke sensor triggers an alarm, the system immediately cuts off unnecessary loads and starts the fire extinguishing system 13. At the same time, the intelligent platform realizes remote monitoring and alarm pushing through the cloud visual interface, realizing unattended operation and maintenance.

[0101] The traditional container machine room is only managed by a separate power distribution cabinet and air conditioning system, lacks intelligent linkage, the temperature control is lagging, the power dispatching efficiency is low, and manual intervention is required when an abnormality occurs; the embodiment realizes integrated monitoring and automatic control through the intelligent integrated system, the equipment energy consumption is reduced by 15%, the fault response time is shortened by more than 50%, and the operation and maintenance efficiency is greatly improved.

[0102] The working principle of the application is as follows:

[0103] The outer surface of the box 11 is sprayed with aerogel material with a thermal conductivity coefficient of 0.012-0.024 W / (m·K), and the thickness is controlled at 3-5 mm, forming a continuous heat insulation layer to effectively block the heat transfer between the inside and outside. Tests show that under extreme temperature-30℃ to 40℃ environment, the temperature difference between the inside and outside of the box can be stably controlled at more than 25℃, directly reducing the air conditioning load by 30%-40%; the joint of the box 11 uses an elastic silicone rubber sealing ring, which realizes tight sealing through internal inflation technology, and the overall protection level reaches IP55. The inflation pressure of the sealing ring can be adjusted to 0.2-0.3 MPa through the intelligent valve, ensuring no leakage under extreme weather conditions such as typhoon wind speed 12 and heavy rain rainfall 50 mm / h; the inner wall of the box 11 is sequentially installed with a 0.5 mm aperture, 20% perforation rate micro-perforated aluminum plate and a 3 mm thick aerogel layer, forming a porous sound-absorbing-heat-insulating composite system. The actual measurement shows that the equipment operation noise is reduced from 65 dB to below 50 dB, with a noise reduction of 15 dB, and the aerogel layer reduces the generation of condensate water, reducing the risk of equipment corrosion.

[0104] The positioned photovoltaic panel 16 is a 450W / block monocrystalline silicon photovoltaic panel with a conversion efficiency of 22.5%, and 4 photovoltaic panels are arranged in each box, with a total power of 1800W. Combined with the intelligent energy management system, the MPPT controller is used to optimize the power generation efficiency, and the daily average power generation of a single box is 6 degrees, with an annual power generation of about 1800 degrees, which meets the basic electricity demand for lighting, equipment standby and other basic electricity demand, and the annual carbon reduction is about 1.8 tons according to the carbon emission coefficient of thermal power 0.982kg / kWh. The integrated 20kWh / 48V iron phosphate lithium battery pack has a cycle life of ≥6000 times, supports off-grid operation and peak-valley electricity price adjustment, and stores energy in the low valley period and discharges in the peak period, reducing the dependence on the power grid by 40%. The roof photovoltaic panel and the top of the box form an air isolation cavity, and a small cooling fan is built-in. When the power is abundant, it automatically starts, reduces the working temperature of the photovoltaic panel by 5-8℃, and improves the power generation efficiency by 3%-5%. The condensate water collection tank capacity is 50L, which recovers the air conditioning condensate water. After filtration, it is pressurized by a high-pressure water pump at 0.4MPa to wash the photovoltaic panel once a week, saving about 120L / month of water. The box perimeter green plants are irrigated and the water mist cooling is automatically started when the ambient temperature is ≥35℃ in summer, reducing the surface temperature of the box by 8-10℃.

[0105] When the photovoltaic panel 16 needs to be cleaned, the water pump 33 is started to pump out the condensate water and deliver it to the water pipe 35, and the water is sprayed to the photovoltaic panel 16 on both sides through the nozzle 351 to wash it. At the same time, the motor 37 drives the rotating disc 38 to rotate, and the eccentric bolt 381 and the connecting rod 39 are matched to control the up and down movement of the bidirectional tooth plate 36, and then the bidirectional tooth plate 36 is engaged with the gear 352 to control the reciprocating swing of the two water pipes 35 within a certain angle to control the impact horizontal diffusion and improve the washing effect. The washing angle should ensure that the water flow can reciprocate between the highest and lowest points of the photovoltaic panel 16.

[0106] The bolt rod 24 is rotated by the motor, and the sliding block 25 slides on the surface of the two fixed rods 23, so that the sliding block 25 can be moved when the bolt rod 24 rotates. At the same time, since the inclined surface 27 is consistent with the inclination angle of the photovoltaic panel 16, the moving plate 28 is in a parallel state with the photovoltaic panel 16, so that the bottom scraping strip 218 is in parallel contact with the photovoltaic panel 16, and the force is uniform. The roller 216 can only roll inside the through slot 41, so that the top of the moving plate 28 will be moved first when the sliding block 25 moves, and the roller 216 at the bottom will be delayed relative to the top of the moving plate 28. In this way, the moving plate 28 will be in an inclined state during scraping and washing, and the top of the moving plate 28 will be cleaned in the forward direction, so as to scrape the sludge downward.

[0107] The swing plate 215 can rotate relative to the connecting cylinder 214, and the slide rod 211 slides along the track of the extending cylinder 29. When not under force, the slide rod 211 as a whole enters the inside of the extending cylinder 29 due to the spring 213. When the slide block 25 moves, the fixed bolt 212 is pulled to slide along the track of the sliding groove 291 due to the inclination, and the spring 213 is compressed. The spring 213 is first deformed, and then the roller 216 moves. When the roller 216 moves to the end, the screw rod 24 reverses, and the top of the moving plate 28 reverses in the same way. At this time, the distance between the slide block 25 and the swing plate 215 gradually decreases, and the spring 213 is compressed. When the slide block 25 and the swing plate 215 are kept at the same relative position, the slide rod 211 is completely retracted into the extending cylinder 29. When the slide rod 211 continues to move, it gradually extends and then drives the roller 216 to roll along the through groove 41. At this time, the moving plate 28 is in the opposite inclined state. This structure can ensure that the moving plate 28 is in the inclined state when scraping mud, and no matter whether it moves forward or backward, the top of the moving plate 28 is inclined to the forward direction, so as to improve the mud scraping effect.

[0108] The above description is only the preferred embodiment of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should be considered as the protection scope of the present application.
