Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electrical protection equipment, in particular to an environmental control device, especially a high-precision environmental control device, and more specifically, a novel environmental control device with high accuracy of environmental parameters. Background Art
[0002] An environmental control device is a device applied to electrical equipment to ensure ventilation, heat dissipation, dust tightness, rain protection, dehumidification, and heat preservation of the electrical equipment. Especially for electrical equipment in current new energy power generation, these electrical equipment are all located in harsh outdoor environments. However, the control system, communication system, and backup power supply system inside the electrical equipment all require a good electrical environment. Therefore, an environmental control device needs to be set outside the electrical equipment to ensure the microenvironment inside the electrical equipment. The environmental control device usually consists of a framework as the main body, and an air inlet window with air inlet louvers is connected to the side for communicating with the external atmosphere. At the same time, an environmental parameter acquisition module for collecting atmospheric environmental parameters is set. The environmental parameter acquisition module includes an environmental sensor and a processing module electrically connected thereto.
[0003] In the most traditional environmental control device, the environmental sensor is installed externally. This installation method is simple, but since the environmental sensor is set outside the framework and exposed to the atmospheric environment, there is a large temperature error due to sunlight irradiation, and at the same time, there is also a large humidity error due to the influence of rain. The environmental control device in this way often causes misoperation of logical control due to inaccurate acquisition of environmental parameters.
[0004] To solve the above problems, an internal installation method of the environmental sensor has emerged. In this method, the environmental sensor is installed inside the framework far from the air inlet window to avoid it contacting the rainwater entering the environmental control device through the air inlet louvers. In this internal installation method, since the environmental sensor is no longer exposed to rain and direct sunlight, the measurement accuracy has been greatly improved compared with the external installation method.
[0005] In the process of implementing the present utility model, the inventor found that there are at least the following problems in the prior art:
[0006] In the above internal installation method, since the installation position of the environmental sensor is far from the air inlet window and close to the inner side of the environmental control device, the air inlet window and the housing have a relatively large shielding effect, and there is a large temperature difference between the installation position and the external atmospheric environment. At the same time, the heat of the electrical equipment inside the environmental control device is easily transferred to the environmental sensor. Therefore, there will be a certain temperature measurement error. And under the influence of a relatively high temperature error, the humidity collected by the environmental sensor is often lower than the actual atmospheric humidity. That is to say, in the internal installation method of the environmental sensor, its measurement accuracy is still relatively low. Therefore, for the environmental control device, how to improve the measurement accuracy of the environmental sensor and avoid misoperation of the environmental control device due to inaccurate acquisition of atmospheric environmental parameters is a problem that needs to be solved. Summary of the Invention
[0007] An embodiment of the present utility model provides a new type of environmental control device with high accuracy of environmental parameters to solve the problem of misoperation of the environmental control device caused by low acquisition accuracy of environmental sensors in the prior art.
[0008] To achieve the above object, an embodiment of the present utility model provides a new type of environmental control device with high accuracy of environmental parameters, including an environmental control device frame, an air inlet window, a ventilation and rainproof box, and an environmental sensor; the air inlet window is hinged to the side surface of the environmental control device frame; the ventilation and rainproof box is a hollow structure with a box body air inlet and an air outlet, and the front side of the ventilation and rainproof box is attached to the inner side surface of the air inlet window; the environmental sensor extends into the ventilation and rainproof box; the air inlet window is also provided with an air inlet hole, and the air inlet hole communicates with the box body air inlet.
[0009] Further, the ventilation and rainproof box is a rectangular strip structure surrounded by a front baffle, two side baffles, a rear baffle, a top plate, and a bottom plate; the box body air inlet is opened on the front baffle, and the air outlet is opened on the rear baffle.
[0010] Further, the environmental sensor includes a lock nut and a sensor probe, a sensor installation hole is opened on the top plate, and the top end of the sensor probe penetrates through the sensor installation hole from bottom to top and meshes with the lock nut.
[0011] Further, the box body air inlet is lower than the air outlet.
[0012] Further, the air inlet hole is an inclined hole with a lower outer side and a higher inner side.
[0013] Further, the bottom plate is an inclined surface with a lower front and a higher rear.
[0014] Further, a plurality of rainproof louvers are provided on the air inlet window, the ventilation and rainproof box is vertically arranged, and the ventilation and rainproof box is located on the side of the rainproof louvers.
[0015] Further, the connection method between the ventilation and rainproof box and the air inlet window is screwing or riveting.
[0016] The above technical solution has the following beneficial effects:
[0017] In this technical solution, by adding a ventilation and rainproof box, the environmental sensor is directly installed on the inner side surface of the air inlet window, and a dedicated air flow channel is formed by the box body air inlet and the air outlet, so that the atmospheric environment in the dedicated air flow channel is kept consistent with the external atmospheric environment, and the interference of the heat dissipated by electrical equipment received by the environmental sensor is reduced, effectively ensuring the accuracy of the atmospheric environment parameters collected by the environmental sensor placed in the dedicated air flow channel, and avoiding the problem of misoperation of the environmental control device due to inaccurate collection of atmospheric environment parameters.
[0018] In addition, the ventilation and rainproof box is also provided with an inclined bottom plate.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.
[0026] As Figure 1 、 Figure 2 shown (the environmental control device frame 5 is actually a three-dimensional structure. For clear display, the attached Figure 1(Only a part of it connected to the air inlet window 1 is shown). To solve the aforementioned problems, an embodiment of the present utility model provides an improved new environmental control device with high accuracy of environmental parameters, which includes an environmental control device frame 5, an air inlet window 1, a ventilation and rainproof box 3, and an environmental sensor 2; the air inlet window 1 is hinged to the side surface of the environmental control device frame 5 for realizing the opening function; the ventilation and rainproof box 3 is a hollow structure provided with a box body air inlet 38 and an air outlet 35, the environmental sensor 2 extends into the ventilation and rainproof box 3, and the air inlet window 1 is also provided with an air inlet hole 11, and the air inlet hole 11 is communicated with the box body air inlet 38. In this way, the box body air inlet 38 and the air outlet 35 constitute a dedicated air flow channel (refer to Figure 3 the arrow indicating the air flow direction in). After the outside air enters the box body air inlet 38 through the air inlet hole 11, it fully contacts the environmental sensor 2 inside the ventilation and rainproof box 3, and then diffuses into the environmental control device through the air outlet 35 (of course, the gas can also flow reversely from the inside to the outside). Since the atmospheric environment in this dedicated air flow channel is consistent with the outside atmospheric environment, it can ensure the accuracy of the atmospheric environment parameters collected by the environmental sensor 2 placed in this dedicated air flow channel; at the same time, in this application, the front side of the ventilation and rainproof box 3 is attached to the inner side surface of the air inlet window 1 (the side of the air inlet window close to the center of the environmental control device frame 5 is the inner side surface) for installation, which itself can make the environmental sensor 2 closer to the outside atmospheric environment, eliminate the influence of the shielding effect of the air inlet window 1 and the housing, and the environmental sensor 2 is far away from the electrical equipment inside the environmental control device, and can be protected from the influence of the heat dissipation of the electrical equipment, which is more conducive to ensuring the measurement accuracy of the atmospheric environment parameters and avoiding the problem of misoperation of the environmental control device due to inaccurate parameter collection.
[0027] Furthermore, as Figure 3 shown, for the convenience of processing and installation, the preferred structure of the ventilation and rainproof box 3 is a long strip box body structure with a rectangular cross-section, which is enclosed by a front baffle 31, two side baffles 32, a rear baffle 36, a top plate 34, and a bottom plate 37; the box body air inlet 38 is opened on the front baffle 31, and the air outlet 35 is opened on the rear baffle 36, so that the dedicated air flow channel, like the rainproof louvers 4 provided on the air inlet window 1, realizes the air intake from the outside to the inside. Further, in order to ensure that the dedicated air flow channel has a sufficient length and the air entering the channel can fully contact the environmental sensor 2, as Figure 3 shown, the box body air inlet 38 can be opened at the bottom of the front baffle 31, and the air outlet 35 can be opened at the top of the rear baffle 36, that is, it is required that the position of the box body air inlet 38 is lower than the position of the air outlet 35, and the sizes of the box body air inlet 38 and the air outlet 35 can be adjusted according to actual needs.
[0028] Further, for the convenience of installation and replacement, the environmental sensor 2 is composed of two parts, a locknut 21 and a sensor probe 22. A threaded section is provided at the top of the sensor probe 22, and the outer diameter of the threaded section is smaller than that of the sensor probe 22. At the same time, a sensor mounting hole 33 is opened on the top plate 34. After the threaded section of the sensor probe 22 penetrates through the sensor mounting hole 33 from bottom to top, the locknut 21 is screwed and tightened.
[0029] Further, the air inlet hole 11 is an inclined hole with a lower outer side and a higher inner side, that is, one end located on the outer side surface of the air inlet window 1 is lower than the end located on the inner side surface of the air inlet window 1 of the air inlet hole 11. To achieve this design, as Figure 4 shown, this kind of air-permeable hole often used in the sheet metal stamping process can be stamped on the plate surface of the air inlet window 1 from the inner side to the outer side, so that a plurality of protrusions are formed on the plate surface. The top of the protrusion is connected to the plate surface of the air inlet window 1, and the bottom of the protrusion is disconnected from the plate surface of the air inlet window 1. This kind of air-permeable hole can form an inclined hole with a lower outer side and a higher inner side, and the top of the protrusion forms a protective surface, which can prevent rainwater from entering the air inlet hole 11 to the greatest extent.
[0030] Further, as Figure 3 shown, the bottom plate 37 is an inclined surface with a lower front and a higher rear. This inclined surface serves as a water trough. Even if a small amount of rainwater enters the air inlet hole 11 when it rains outside, the rainwater will not flow upward. In this way, when effectively collecting atmospheric environment parameters, it will not be affected by rainwater.
[0031] Further, a plurality of rainproof louvers 4 are provided on the air inlet window 1, and the ventilation and rainproof box 3 is vertically arranged. To avoid being affected by the rainproof louvers 4, as Figure 1 described, the ventilation and rainproof box 3 should be arranged on the side of the rainproof louvers 4.
[0032] Further, the connection method between the ventilation and rainproof box 3 and the air inlet window 1 can be various, for example, it can be screwed or riveted. For this purpose, a through hole 12 can be opened on the plate surface of the air inlet window 1, and a box body fixing hole 39 corresponding to the through hole 12 can be opened on the front baffle 31 of the ventilation and rainproof box 3. Then, a rivet or a bolt is sequentially passed through the through hole 12 and the box body fixing hole 39 to fix the ventilation and rainproof box 3 and the air inlet window 1.
