The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The utility model aims to provide a data acquisition box suitable for extreme weather, which can be used for ensuring that the data acquisition box can adapt to extreme weather such as high temperature and humidity, so that the service life is prolonged, the data acquisition accuracy is improved, and the working efficiency is improved.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
As shown in fig. 1 and fig. 2, the data collection box adaptable to extreme weather provided by the utility model comprises: power supply unit 5, intelligent data acquisition unit 4, box 1, dampproofing box 2 and thermal fan unit 3.
The moisture-proof box 2 is arranged on one side wall of the box body 1. The thermo-sensitive fan unit 3 is disposed inside the case 1, and the thermo-sensitive fan unit 3 is disposed between the power supply unit 5 and the intelligent data collecting unit 4.
The thermo-fan unit 3 serves to discharge heat inside the case 1. The moisture-proof case 2 is used for adsorbing moisture in the air inside the case 1.
The thermosensitive fan and the moisture-proof box 2 are detachable structures of the box body 1, and the power supply unit 5 and the intelligent data acquisition unit 4 are installed subsequently. The power supply unit 5 and the intelligent data acquisition unit 4 are respectively installed on two sides of the thermal fan unit 3, and the thermal fan unit 3 simultaneously dissipates heat and cools the power supply unit 5 and the intelligent data acquisition unit 4 and is powered by the power supply unit 5. The work of adjusting the environment in the box and changing the temperature and humidity is completed through the cooperation of all the units, so that the optimal working condition is provided for the intelligent data acquisition unit 4 in the acquisition box.
In order to enable the hot air discharge efficiency to be matched with the fan rotation speed, as shown in fig. 3, the present invention employs a thermo-fan unit 3 including: a thermistor 31, a first heat radiation fan 32, a discharge fan 33, a terminal, and a second heat radiation fan 34.
The first radiator fan 32, the discharge fan 33, and the second radiator fan 34 are connected in parallel through connection terminals. The thermistor 31 is connected in series with the connection terminal.
The rotation speeds of the first heat dissipation fan 32, the exhaust fan 33, and the second heat dissipation fan 34 are varied according to the resistance value of the thermistor 31. The first and second heat dissipation fans 32 and 34 are used to draw hot air inside the cabinet 1. The exhaust fan 33 serves to discharge the extracted hot air out of the cabinet 1. When the refrigerator operates, the first cooling fan 32 and the second cooling fan 34 quickly pump out high-temperature air in the refrigerator body 1, and then the high-temperature air is exhausted out of the refrigerator through the exhaust fan 33, so that quick flowing exchange of air inside and outside the refrigerator is realized, and heat in the refrigerator is exhausted out of the refrigerator, so that the temperature is reduced, and heat is effectively dissipated.
The thermistor 31 is a negative temperature coefficient thermistor 31, for example, the MF53 thermistor 31, and the MF53 thermistor 31 adopts the environmental test standard for GB/T2423.1 electrical and electronic products when in use. With the temperature rise, the ntc thermistor 31 decreases exponentially, and the current passing through the resistance at room temperature allows the first cooling fan 32, the exhaust fan 33, and the second cooling fan 34 to operate at low speed, so that the requirement of discharging heat generated in the tank can be met. When meetting hot weather or the perpendicular incidence of the sun data acquisition case, data acquisition case inside temperature can rise gradually, and thermistor 31's resistance also can reduce thereupon, can know through ohm law (I ═ U/R), under the condition of stable power supply (voltage is unchangeable), the resistance reduces, and the electric current that passes through increases, and each fan rotational speed improves, greatly increased radiating effect. On the contrary, when the weather is low, the temperature is reduced, the resistance is increased, and the rotating speed of each fan is reduced by reducing the passing current. When the temperature is extremely low in winter, the passing current is extremely low, and the fan stops rotating.
The thermosensitive fan unit 3 is fixedly connected with the box body 1 through screws, the back of the data acquisition box is shown in figure 5 and is provided with a square opening 11 with the same size as the exhaust fan 33, the back of the thermosensitive fan unit 3 is shown in figure 4, the exhaust fan 33 is a protruding part, and the exhaust fan 33 is inserted into the square opening 11 on the back of the data acquisition box and extends out of the data acquisition box so as to exhaust air conveniently.
Further, in order to effectively absorb moisture in the humid air in the box, as shown in fig. 6, an air hole 22 is formed in the middle of the moisture-proof box 2, the adsorbent 21 is placed inside the moisture-proof box, and the shell can be detached so as to conveniently replace the adsorbent 21. For example, the adsorbent 21 is an alumina adsorbent, which is a white spherical porous particle having characteristics of uniform particle size, smooth surface, high mechanical strength, high hygroscopicity, and the like. When the air conditioner is in continuous humid or extremely foggy weather, the alumina adsorbent can absorb moisture in humid air in the box, keep dry and avoid short circuit of a circuit due to humidity. The alumina adsorbent does not expand and crack after absorbing water and keeps the original shape, is non-toxic, tasteless and odorless, and does not influence the power supply unit 5 and the intelligent data acquisition unit 4 in the box body 1. The alumina adsorbent mainly accords with the Chinese national standard GB/T4294-199 when in use.
The back of the moisture-proof box 2 can be set to be a flat plane and is adhered with the data acquisition box by a KJ-460 structural adhesive, and the structural adhesive has the temperature resistance range of minus 40 ℃ to 80 ℃, the adhesive strength is high, and the corrosion resistance is good. The KJ-460 structural adhesive needs to meet the national GB/T156-008/IS 0171:004 structural adhesive bonding metal and plastic surface treatment guide rules of China.
Further, in order to improve the dustproof and waterproof effects, the size of the box body 1 adopted by the utility model is determined according to the actual use scene, and the material of the box body 1 is stainless steel, so that the box body 1 has the characteristics of high hardness, good corrosion resistance and the like.
And a gap of the box body 1 is sealed by a black rubber pad to prevent dust and rainwater from permeating. The box body 1 is provided with a handle 12, so that the door can be opened towards the right side and locked, as shown in fig. 7 and 8. The whole data acquisition box is arranged near the field equipment and can be fixed on the wall surface or the ground by adopting welding, bolt fixing and other modes.
The data acquisition box suitable for extreme weather has the greatest advantages of simple principle, convenience in implementation and low cost, can automatically adjust the temperature in the protection box, can adapt to extreme hot and humid environments, prevents the influence of high temperature and humidity on equipment in the box, and prolongs the service life of the equipment in the box. And the speed of the rotating speed of the fan can be automatically adjusted by the thermosensitive fan unit along with the change of the environmental temperature, so that the acquisition unit in the acquisition box always works at a proper temperature. When the outdoor temperature is too low in winter, the work can be automatically stopped, and excessive heat dissipation and electric energy waste are avoided. The alumina adsorbent in the moisture-proof box has low cost, good moisture absorption effect, no color and no smell, and unchanged volume after water absorption, has no influence on the operation of equipment in the protection box, and can be replaced at any time to ensure long-term use.
The embodiments in the present description are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other.
The principles and embodiments of the present invention have been described herein using specific examples, which are provided only to help understand the method and the core concept of the present invention; meanwhile, for a person skilled in the art, according to the idea of the present invention, the specific embodiments and the application range may be changed.
