Description

Technical Field

[0001] The present invention relates to the technical field of ventilation equipment, and in particular to an integrated cabinet self-cleaning ventilation equipment and a control method. Background Art

[0002] China Mobile, China Unicom and China Telecom jointly established China Tower Corporation in July 2014. China Tower manages more than 6 million base stations across the country, accounting for about 90% of the total number of base stations of the three major operators. With the construction of 5G, communication base stations will inevitably increase in large numbers, and the main increase is the integrated cabinet station.

[0003] At present, the integrated cabinets use a micro air conditioner with a cooling capacity of 1000-1500W for cooling. In July, August and September in summer, a large number of integrated cabinets generate high temperature alarms. The air conditioners of integrated cabinets have a high failure rate in summer, and air conditioner manufacturers cannot repair them in time. The tower maintenance personnel have a heavy workload, and ensuring normal communication is the top priority. The integrated air conditioner failure alarm and high temperature alarm make the maintenance personnel run around, and the alarm records will be evaluated by the competent department. As a result, the communication equipment cannot work properly, and the consequence is a fine on the maintenance company and withdrawal from the next bidding qualification. Therefore, in order to ensure the normal operation of the integrated base station on hot days, most cabinets have to open the cabinet doors to eliminate the alarm, which has a serious impact on the safe operation of the equipment.

[0004] The integrated fresh air introduces the cold air outside the cabinet into the cabinet through the air inlet through the filter, and discharges the heat inside the cabinet to the outside of the cabinet through the air outlet. Functions: Through the cabinet environment monitoring platform, collect temperature, humidity, and air pressure for intelligent control, link the cabinet air conditioner, and solve the cabinet high temperature alarm.

[0005] Running a large number of integrated fresh air will reduce the use of air conditioners in integrated cabinets. Fresh air equipment can not only solve the problem of high temperature alarm in cabinets, but also save energy. The total power consumption of fresh air equipment is about 20% of air conditioners. Each set of integrated cabinet air conditioners consumes 2,400 kWh of electricity per year. There are more than 2 million integrated cabinets in the country, consuming billions of kWh of electricity each year. The base for energy saving and consumption reduction is very large. We actively respond to the national call for energy conservation and emission reduction, and steadily promote carbon peak and carbon neutrality. The products mainly solve energy conservation and consumption reduction in base stations and computer rooms, reduce operation and maintenance costs, and detect and control the computer room environment through intelligent supporting equipment. The fields to which they belong are energy conservation, emission reduction, environmental protection, and high-end equipment manufacturing.

[0006] In general, the prior art has the following disadvantages:

[0007] 1) The existing fresh air is composed of a casing, a fan, a filter, and a mechanism. Around 2017, 140,000 sets of equipment were installed nationwide. The use environment is complex. The cabinet is installed on the roadside, in an industrial park, etc. There will be catkins, hair, leaves, construction dust, sand, etc., which means that the filter will be blocked after about 3 months of use, and basically all of them will stop being used.

[0008] 2) The existing fresh air system solves the clogging problem by replacing the filter. The frequency of replacing the filter is too high, and many cannot be replaced in time. Therefore, the filter clogging problem cannot be solved at all, and the maintenance timeliness problem is also a problem.

[0009] 3) The existing fresh air filter generally uses ordinary primary filter cotton. Dust enters the filter cotton and is difficult to clean. In addition, the humidity is too high, and the filter will be blocked and rotten after a long time. Summary of the invention

[0030] Furthermore, it also includes a power monitoring platform, and the control module is connected to the power monitoring platform via 485 / 4G / 5G communication.

[0031] Furthermore, the box body includes an upper plate and a lower plate, and a support plate and an optical axis are respectively longitudinally arranged between the upper plate and the lower plate;

[0053] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0054] like Figure 1 , Figure 2 As shown, the integrated cabinet self-cleaning ventilation device described in this embodiment includes a box body 24, a front panel 21 and a rear door panel 23 are arranged in the box body 24, a fan 22 is embedded in the front panel 21, a rain and insect prevention device is arranged at the outlet of the fan 22, a filter cover plate 26 is synchronously arranged on the two sides of the box body 24 or separately arranged on the rear door panel 23 of the box body 24, and an air inlet is arranged on the filter cover plate 26, and the air inlet is specifically a shutter window 25;

[0055] The air inlet is provided with a filter unit corresponding to the air inlet, and the filter unit includes a filter cover plate 26, a filter plate 27, a filter 28 and a diamond mesh 29;

[0056] The filter unit of this embodiment is made of diamond mesh and polyester thread according to the upper and lower locking mesh surfaces, the first layer of diamond mesh is made of stainless steel wire mesh with no less than 40 mesh, and the second layer of filter is made of polyester thread; or the first layer of filter is 10 mesh diamond mesh; the second layer of filter is G4 grade filter;

[0057] At the same time, this embodiment also includes a temperature and humidity detection module, a control module, a filter self-cleaning device and a power monitoring platform; the temperature and humidity detection module, the fan 22, and the filter self-cleaning device are respectively connected to the control module for communication.

[0058] The control module is connected to the power monitoring platform via 485 / 4G / 5G communication.

[0059] Among them, the filter self-cleaning device includes a diamond mesh brush 16, a reduction motor 8, a transmission mechanism and a movable plate 2; the reduction motor 8 is connected to the movable plate 2 via the transmission mechanism; the diamond mesh brush 16 is connected to the movable plate 2 through the brush rack 15, and the up and down movement of the movable plate 2 brings about the up and down movement of the diamond mesh brush 16, thereby cleaning the diamond mesh 29; the reduction motor 8 is communicatively connected to the control module.

[0060] The filter self-cleaning device further comprises a filter brush strip 14 ; the filter brush strip 14 is fixed on the movable plate 2 , and the upward and downward movement of the movable plate 2 drives the filter brush strip 14 to move upward and downward, thereby cleaning the dust attached to the filter 28 .

[0061] For the transmission mechanism, the box body 24 includes an upper plate 1 and a lower plate 3, and a support plate 6 and an optical axis 7 are respectively arranged longitudinally between the upper plate 1 and the lower plate 3; a pair of support plates 6 are arranged opposite to each other to play a supporting role; two optical axes 7 and two screw rods 13 are respectively arranged opposite to each other along the diagonal direction; a screw rod synchronization wheel 20 is arranged at the bottom of the screw rod 13; and an optical axis tensioning wheel 17 is arranged at the bottom of the optical axis 7.

[0062] like Figure 3 , Figure 4 As shown, the transmission mechanism of the embodiment of the present invention is specifically described below in combination with the working principle of the embodiment of the present invention:

[0063] When the temperature detected by the temperature sensor placed in the integrated cabinet reaches the set value (for example, the temperature difference between the inside and outside of the cabinet is 5°C), the fan 22 starts, the system turns off the cabinet air conditioner, and the outdoor cold air enters the cabinet through the air inlet louver 25.

[0064] At 1:00 a.m. and 3:00 a.m., the 22nd fan is turned off, and the 8th reduction motor is started at the same time. The 9th synchronous wheel connected to the 8th reduction motor drives the 12th synchronous wheel through the 10th motor belt. The 12th synchronous wheel is fixed together with the 13th screw rod. The 13th screw rod drives and drives the 18th synchronous wheel belt to rotate, so that the 4 synchronous wheels at the bottom rotate. The rotation of the 13th screw rod drives the 31st screw rod nut to move up and down. Since the 2nd movable plate is fixed together with the 31st screw rod nut, the 2nd movable plate moves up and down. The 16th diamond mesh brush is connected to the 2nd movable plate through the 15th brush rack. The up and down movement of the 2nd movable plate brings the up and down movement of the 16th diamond mesh brush, so that the 29th diamond mesh can be cleaned to clean the catkins sucked in by the 22nd fan and attached to the 29th diamond mesh. The 14th filter mesh brush strip is fixed on the 2nd movable plate. The up and down movement of the movable plate drives the up and down movement of the 14th filter mesh brush strip, so that the dust attached to the 28th filter mesh can be cleaned. As the 2 movable plates move up and down, when the 4 upper travel switch or 5 lower travel switch is touched, the 30 main board will give the 8 reduction motor a reverse signal, causing the 8 reduction motor to rotate in the opposite direction, thereby causing the 2 movable plates to rotate in the opposite direction, achieving automatic dust cleaning, and allowing clean outdoor air to enter the integrated cabinet through the 32 air outlets. After each up and down cycle, the 8 reduction motor stops running, and the 22 fan starts at the same time.

[0065] In general, the present invention collects the air pressure, temperature and humidity inside and outside the cabinet through the control system, and uploads the collected data to the power monitoring platform through 485 / 4G, and the platform sets the intelligent management of the fresh air equipment. The workflow is:

[0066] 1. When the temperature inside the cabinet reaches the set value (for example, the temperature difference between the inside and outside of the cabinet is 5°), the fresh air starts;

[0067] 2. When fresh air is started, the cabinet air conditioner is automatically shut down, and the fan introduces outdoor cold source to achieve a cooling effect inside the cabinet; ① Air enters through the shutters on both sides of the metal box (with air pressure convection, rain protection, dehumidification, isolation of leaves, animals, etc.); ② The first layer of filter is a diamond mesh with about 10 meshes, which can block catkins, mosquitoes, spider webs, large particles of dust, etc.; ③ The second layer of filter is a special G4-level filter to purify fine dust so that the cold source entering the cabinet meets the G4 standard; ④ The fan draws air into the cabinet; ⑤ The outlet fan starts working, and the air outlet has a rain and insect protection device.

[0068] 3. When the intelligent management platform detects that the wind pressure inside and outside the air inlet drops to the set value (for example, the difference between the wind pressure inside and outside the cabinet is 50%), the dust removal device is intelligently started to remove impurities and dust from the first and second filter layers; the intelligent platform can also set a fixed time for cleaning between 00:00 and 6:00 every day according to the requirements of the operator's dynamic environment monitoring platform (because this time period is the operator's exemption period, and the fresh air equipment shutdown alarm is not within the maintenance scope).

[0069] In summary, the present invention can solve practical problems in on-site use. The self-cleaning first filter can solve: catkins, leaves, hair, etc.; the self-cleaning second filter can solve dust, and purify the air for a long time to meet the G4 standard. The filter of the present invention is made of diamond mesh and polyester thread according to the upper and lower locking mesh surfaces. The first layer of diamond mesh is made of stainless steel wire mesh of not less than 40 mesh, and the second layer of filter is made of polyester thread. This filter can be reused and has a service life of not less than 5 years. The system of the present invention intelligently collects the pressure difference inside and outside the cabinet, the temperature and humidity difference, etc. to set the intelligent shutdown and start equipment, self-cleaning system, and linkage shutdown and start air conditioning.

[0070] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
