[0033] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0034] like Figure 1 and Figure 2 As shown, a thermal control box 100 of a power plant according to an embodiment of the present invention comprises a box body 1 and a dehumidification device 2. The box body 1 has a dehumidification chamber 11 and a plurality of installation chambers 12 for installing a control device. The installation chamber 12 is connected to the dehumidification chamber 11. The dehumidification device 2 has a connecting end, which is connected to the dehumidification chamber 11 so as to utilize the dehumidification device 2 to dehumidify the installation chamber 12.

[0035] The thermal control box 100 of a power plant in an embodiment of the present invention divides the space in the box body 1 into a plurality of installation cavities 12, which can reduce the air flow between different installation cavities 12, thereby reducing the diffusion of air humidity; the dehumidification device 2 is used to dehumidify the plurality of installation cavities 12. Since the volume of a single installation cavity 12 is relatively small, it is more conducive to the air flow in the installation cavity 12, which can improve the dehumidification efficiency and can quickly reduce the air humidity in the installation cavity 12, thereby protecting the electrical components and metal parts in the thermal control box 100 of the power plant.

[0036] The control device is a controller, such as a temperature controller, a pressure controller, a flow controller, etc., which can realize automatic control and management of the thermal system of the power plant. Of course, other electrical components are also arranged in the installation cavity 12, such as an overload protection device for circuit protection, etc.

[0037] Alternatively, if Figure 1 and Figure 2 As shown, a mounting frame 122 is provided in the mounting cavity 12 , and the mounting frame 122 is fixedly connected to the cavity wall of the mounting cavity 12 by bolts.

[0038] Thus, mounting holes can be prefabricated on the mounting frame 122 to facilitate the installation of the controller and other electrical components.

[0039] Optionally, the dehumidification device 2 is a dehumidifier.

[0040] The dehumidifier has a good dehumidification effect and can achieve efficient dehumidification of multiple installation cavities 12 at the same time.

[0041] In some embodiments, Figure 1 and Figure 3 As shown, the box body 1 includes a dehumidification enclosure 111 and a first partition 121. The dehumidification enclosure 111 encloses a dehumidification chamber 11. A plurality of installation chambers 12 are arranged adjacent to each other in sequence along the circumference of the dehumidification chamber 11. The first partition 121 is arranged between two adjacent installation chambers 12. The dehumidification enclosure 111 has a dehumidification channel 1111 connecting the dehumidification chamber 11 and the installation chamber 12.

[0042] The dehumidification chamber 11 is connected to the multiple installation chambers 12 through the dehumidification channels 1111 respectively, so that the dehumidification device 2 directly dehumidifies the multiple installation chambers 12 through the dehumidification chamber 11, thereby achieving a better dehumidification effect.

[0043] As an example, Figure 1 and Figure 3As shown, the outer contour of the box body 1 is rectangular and has a front side and a rear side. When the thermal automation control of the power plant is in use, the front wall and the rear wall of the box body 1 are perpendicular to the ground; a door is provided on the front side of the box body 1 to facilitate the installation and maintenance of the controller in the installation cavity 12; the dehumidification device 2 is provided on the rear side of the box body 1, and the connecting end of the dehumidification device 2 is connected to the dehumidification pipe 21, and the end of the dehumidification pipe 21 away from the dehumidification device 2 passes through the rear wall of the box body 1 and extends to the dehumidification cavity 11, and is sealed with the rear wall of the box body 1.

[0044] The dehumidification enclosure 111 includes four plate portions 1112, and the four plate portions 1112 enclose a dehumidification chamber 11 with a square cross-section. The dehumidification enclosure 111 is arranged at the center of the box body 1, and its four sharp corners point to the four side walls of the box body 1 respectively; there are four first partitions 121, and the four first partitions 121 are respectively connected to the four sharp corners of the dehumidification enclosure 111, that is, the four first partitions 121 are arranged in a cross shape, thereby dividing the internal space of the box body 1 into four installation chambers 12 that are arranged adjacent to each other in the circumferential direction of the dehumidification chamber 11; the plate portions 1112 correspond to the installation chambers 12 one by one, and the dehumidification channel 1111 is arranged through the thickness direction of the plate portions 1112, which can connect the dehumidification chamber 11 and the installation chamber 12.

[0045] Therefore, the dehumidification device 2 can simultaneously realize the dehumidification work of the four installation cavities 12, reduce the air humidity in the installation cavity 12, and thus protect the electrical components and metal parts in the thermal control box 100 of the power plant.

[0046] In some embodiments, Figure 4 and Figure 5 As shown, the thermal control box 100 of the power plant further includes a filter screen 112 , and the filter screen 112 blocks the dehumidification channel 1111 .

[0047] By providing the filter 112, the air can be filtered, reducing the probability of dust and impurities entering the installation cavity 12 along with the air, thereby reducing the risk of the control device being contaminated by dust and impurities and malfunctioning.

[0048] Optionally, the filter screen 112 is detachably connected to the dehumidification enclosure 111 .

[0049] Thereby, the maintenance convenience of the filter 112 can be improved.

[0050] In some embodiments, Figure 5 As shown, the thermal control box 100 of the power plant further includes a plurality of first door bodies 3 , each of which corresponds to the installation cavity 12 one by one. The installation cavity 12 has an installation opening 123 , and the first door bodies 3 are movably connected to the box body 1 and can block the installation opening 123 .

[0051] Through the above arrangement, each installation cavity 12 corresponds to a first door body 3, which can realize independent closure of the installation cavity 12, and further realize separate maintenance and management of the installation cavity 12; for example, when the control device in one of the installation cavities 12 needs maintenance, only the first door body 3 of the installation cavity 12 can be opened, and the doors of the other installation cavities 12 remain closed, thereby maintaining the normal operation of the control devices in the other installation cavities 12 and preventing dust and other impurities from entering the other installation cavities 12 and causing contamination of the control devices.

[0052] As an example, Figure 5 As shown, the front side of the installation cavity 12 is open to form the above-mentioned installation opening 123, and one side of the first door body 3 is hinged to the box body 1, so that the installation opening 123 can be switched between a state and a blocked state.

[0053] Of course, in other embodiments, the first door body 3 may also be connected to the box body 1 in other movable connection ways, as long as the first door body 3 can be opened and closed.

[0054] In some embodiments, Figure 1 and Figure 5 As shown, a limiting member is provided in the installation cavity 12 , and when the first door body 3 is blocked at the installation opening 123 , the first door body 3 stops at the limiting member.

[0055] By providing the limiting member, the first door body 3 can be limited, thereby improving the stability of the first door body 3 during use.

[0056] As an example, Figure 1 As shown, two limiting members are provided in each installation cavity 12, and the limiting members are limiting plates 14 in the shape of a right-angled triangle. The two limiting plates 14 are respectively provided at two opposite corners of the installation cavity 12, which can reinforce the corner positions of the installation cavity 12, and the limiting plates 14 are welded and fixed to the box body 1; when the first door body 3 is closed, the first door body 3 stops at the two limiting plates 14, and the two limiting plates 14 can limit the two diagonal positions of the first door body 3, thereby achieving a better limiting effect, so that the position of the first door body 3 is relatively stable.

[0057] Optionally, a sealing ring is provided on the first door body 3 .

[0058] Thereby, the sealing performance of the first door body 3 when closed can be improved, thereby further reducing the probability of dust impurities in the external environment entering the installation cavity 12.

[0059] In some embodiments, Figure 6 and Figure 7 As shown, the thermal control box 100 of the power plant further includes a second door body 4 , which covers the plurality of first door bodies 3 and is movably connected to the box body 1 .

[0060] By providing the second door body 4 , which is provided on the outside of the first door body 3 , the plurality of first door bodies 3 can be further reinforced, thereby improving the stability of the overall structure of the thermal control box 100 of the power plant.

[0061] As an example, Figures 5 to 7 As shown, the second door body 4 matches the size of the front wall of the box body 1, and the second door body 4 is hinged to the box body 1, and its hinge axis is vertically arranged; thus, the operator can open the second door body 4 to one side so that multiple first door bodies 3 are exposed to the outside, so as to install and inspect the control device in the installation cavity 12 in real time.

[0062] Of course, in other embodiments, the second door body 4 may also be connected to the box body 1 in other movable connection ways, as long as the second door body 4 can be opened and closed.

[0063] In some embodiments, the first door body 3 is made of a transparent material, and the second door body 4 has a plurality of transparent portions 41 , which are arranged corresponding to the first door body 3 so that the installation cavity 12 can be observed through the transparent portions 41 and the first door body 3 .

[0064] Through the above arrangement, the operator can observe the situation in the installation cavity 12 through the transparent portion 41 and the first door body 3, which is more conducive to the daily inspection of the thermal control box 100 of the power plant; in addition, when a fault occurs in the thermal control box 100 of the power plant, the situation of each control device can be preliminarily judged without opening the first door body 3 and the second door body 4, which can assist the operator to take appropriate treatment measures in time.

[0065] As an example, Figure 6 and Figure 7 As shown, the number of transparent parts 41 is the same as the number of mounting cavities 12, and the four transparent parts 41 are distributed in two rows and two columns, and the transparent parts 41 correspond to the positions of the mounting frame 122 in the mounting cavity 12; thus, the operator can directly observe the status of each control device on the mounting frame 122 through the transparent parts 41.

[0066] In some embodiments, the box body 1 further has a cable cavity 13, which is disposed adjacent to the installation cavity 12, a second partition plate 131 is disposed between the cable cavity 13 and the installation cavity 12, and both the first partition plate 121 and the second partition plate 131 have threading holes.

[0067] It is known that a variety of controllers and electrical components are integrated inside the thermal control box 100 of a power plant, and the internal cable arrangement is relatively complicated and inconvenient to store.

[0068] Through the above arrangement, the cables of the multiple control devices connected to the thermal control box 100 of the power plant can be stored and organized in the cable cavity 13, and then uniformly passed out of the box body 1, making the cables more neat.

[0069] As an example, Figure 3 and Figure 4 As shown, each of the four first partitions 121 is provided with a first wire threading hole 1211 in the form of an elongated strip, and the cables of the control devices in two adjacent installation cavities 12 can be connected to each other through the first wire threading hole 1211 .

[0070] like Figure 8 As shown, there are two cable cavities 13, which are arranged on both sides of the box body 1 relatively to each other, and one cable cavity 13 corresponds to two installation cavities 12 arranged up and down; the second partition plate 131 has a second threading hole 1311 which is arranged through, and the second threading hole 1311 is in the shape of a long strip. There are two second threading holes 1311, and the two second threading holes 1311 correspond to the two installation cavities 12 arranged up and down, respectively; thus, the cables of the control device in the two installation cavities 12 arranged up and down can pass through the two second threading holes 1311, respectively.

[0071] Two cable seats 5 are fixedly connected to the upper side of the box body 1, and the two cable seats 5 are respectively arranged on the upper sides of the two cable cavities 13; the cable seats 5 have cable holes, and the cable holes are connected to the cable cavities 13; thus, multiple cables of the thermal control box 100 of the power plant can be passed through the cable holes and placed outside the box body 1, thereby improving the neatness of the cables.

[0072] In some embodiments, a cable rack 132 for arranging cables is disposed in the cable cavity 13 , and the cable rack 132 has a plurality of cable management slots.

[0073] By providing the cable management groove, multiple cables can be arranged neatly in the cable cavity 13, thereby further improving the neatness of the cable arrangement and being more conducive to the installation and maintenance of the cables.

[0074] As an example, Figure 1 As shown, the cable rack 132 is in the shape of an elongated strip and is arranged vertically. There are multiple cable management grooves, and the multiple cable management grooves are evenly arranged along the length direction of the cable rack 132 .

[0075] In some embodiments, Figure 4 and Figure 5 As shown, the power plant thermal control box 100 further includes a third door body 6, and a maintenance opening 134 is provided on the side of the cable cavity 13 away from the installation cavity 12. The third door body 6 blocks the maintenance opening 134 and is movably connected to the box body.

[0076] Through the above arrangement, when it is necessary to organize or repair the cables, the third door 6 can be opened, which makes the operation more convenient.

[0077] Optionally, the third door 6 is hinged to the box body 1 .

[0078] Of course, in other embodiments, the third door 6 may also be connected to the box body 1 in other movable connection ways, as long as the cable cavity 13 can be opened and closed.

[0079] As an example, Figure 4 and Figure 5 As shown, there are two third door bodies 6 , which are arranged on two sides of the box body 1 and are used to block the inspection openings 134 of the two cable cavities 13 respectively.
