[0033] In order to enable those skilled in the art to better understand the technical solutions of the embodiments of the present disclosure, the embodiments of the present disclosure are further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0034] like Figure 1 and Figure 2 As shown, the embodiment of the present disclosure provides a dehumidification device 100 for electrical equipment in a thermal power plant, comprising a base 110 and a dehumidification component 120 and a moisture treatment component 130 which are relatively spaced apart and arranged on the base.

[0035] The thermal power plant equipment is arranged between the dehumidification component 120 and the moisture treatment component 130. The dehumidification component 120 is used to dehumidify the thermal power plant equipment, and the generated moisture enters the moisture treatment component 130 for treatment.

[0036] The dehumidification assembly 120 includes a lifting drive mechanism and a dehumidification mechanism connected to the lifting drive mechanism. The lifting drive mechanism 120 is used to drive the dehumidification mechanism to lift and lower.

[0037] Specifically, the thermal power plant equipment that needs to be dehumidified is placed in the dehumidification component 120 and the moisture treatment component 130. According to the height of the thermal power plant equipment, the height of the dehumidification mechanism is adjusted by the lifting drive mechanism, and the entire dehumidification mechanism is turned on to dehumidify the thermal power plant equipment. The moisture generated after dehumidification is treated by the moisture treatment component 130.

[0038] The dehumidification device for thermal power plant equipment of the disclosed embodiment places the thermal power plant equipment between the dehumidification component and the moisture treatment component for dehumidification. There is no need to place the electrical equipment in the inner cavity of the dehumidification device, which facilitates the dehumidification of multiple electrical equipment of different specifications. The operation is simple and the dehumidification efficiency is high. In addition, the lifting drive mechanism can drive the dehumidification mechanism to rise and fall, and then the dehumidification height can be adjusted to meet the dehumidification needs of electrical equipment of different heights, and the application range is wide.

[0039] For example, Figure 2 As shown, the moisture processing assembly 130 includes a sponge absorption plate 131 and a cooling plate 132 connected to the sponge absorption plate 131 .

[0040] The sponge absorption plate 131 is arranged toward the dehumidification assembly 120 and is used to absorb moisture after dehumidification of the thermal power plant equipment.

[0041] Specifically, Figure 2 As shown, in this embodiment, the sponge absorption plate 131 is a circular plate, and the circular sponge absorption plate 131 is composed of a plurality of concentric sponge rings. The area of ​​the sponge absorption plate 131 should cover the lifting range of the dehumidification mechanism to ensure that the sponge absorption plate 131 can absorb moisture when dehumidifying thermal power plant equipment at different heights.

[0042] It should be noted that the shape of the sponge absorption plate 131 is not specifically limited in this embodiment and can be selected according to actual needs.

[0043] The cooling plate 132 is arranged away from the dehumidification assembly 120 and is used to condense moisture that is not absorbed by the sponge absorption plate 131 .

[0044] Specifically, in this embodiment, the shape of the cooling plate 132 matches the shape of the sponge absorption plate 131. The cooling plate 132 includes a circular plate at the edge region and a horizontal plate spaced between the circular plate. The edge region of the cooling plate 132 can be connected to the edge region of the sponge absorption plate 131 by a plurality of fixing rods 133.

[0045] In this embodiment, the sponge absorption plate 131 can dry and absorb the moisture blown out of the electrical equipment, and the unabsorbed moisture can be condensed into water flow through the cooperation of multiple cooling plates 132.

[0046] For example, Figure 2 and Figure 3 As shown, the dehumidification device 100 for thermal power plant equipment further includes a cleaning component 140 , and the cleaning component 140 is movably connected to a side of the sponge absorption plate 131 facing the dehumidification component 120 .

[0047] In this embodiment, the surface of the sponge absorption plate 131 can be cleaned by setting up the cleaning component 140, thereby reducing the difficulty of cleaning the sponge absorption plate 131, thereby reducing the interference of dust on the surface of the sponge absorption plate 131, avoiding the sponge absorption plate 131 from becoming dirty, further affecting the normal use of the dehumidification device, and ensuring the normal use of the dehumidification device.

[0048] For example, Figure 2 and Figure 3 As shown, the cleaning assembly 140 includes a rotating plate 141 and a scraper 142 disposed at the bottom of the rotating plate 141. In this embodiment, the scraper 142 is in a triangular structure, and the scraper 142 and the sponge absorption plate 130 are fitted together.

[0049] The first end of the rotating plate 141 is rotatably connected to the central area of ​​the sponge absorption plate 131 , and the second end of the rotating plate 141 is selectively connected to the edge area of ​​the sponge absorption plate 131 .

[0050] When cleaning is needed, the second end of the rotating plate 141 is separated from the sponge absorption plate 131 and rotates along the first end of the rotating plate 141 on the surface of the sponge absorption plate 131, thereby driving the scraper 142 to rotate to clean the dust on the surface of the sponge absorption plate 131.

[0051] In this embodiment, by providing the rotating plate 141 and the scraper 142, the sponge absorption plate 131 can be cleaned to ensure the normal use of the dehumidification device.

[0052] For example, Figure 2 and Figure 3As shown, the cleaning assembly 140 further includes a pull rod 143; the rotating plate 141 is provided with a positioning hole penetrating the thickness direction thereof, and the pull rod 143 is slidably arranged in the positioning hole; wherein, when the pull rod 143 is pulled outward, the second end of the rotating plate 141 is separated from the sponge absorption plate 131. The positioning hole can limit the pull rod 143 to prevent the pull rod 86 from shaking.

[0053] For example, Figure 3 As shown, the cleaning assembly 140 further includes a reset elastic member 144 , which is sleeved on the outer side wall of the pull rod 143 and located between the inner side wall of the positioning hole and the outer side wall of the pull rod 143 .

[0054] Specifically, in this embodiment, the reset elastic member 144 can adopt a reset spring, the center point of the reset spring and the center point of the pull rod 143 coincide with each other, and the middle of the outer surface of the pull rod 143 is located inside the hollow circle at one end of the reset spring, which can facilitate the movement of the pull rod 143 and reduce the difficulty of moving the pull rod 143.

[0055] Exemplarily, a protective pad is provided at one end of the pull rod 143 facing the sponge absorption plate 131 , and the protective pad can increase the friction between the sponge absorption plate 131 and the pull rod 143 to prevent the rotating plate 141 from rotating.

[0056] For example, Figure 1 and Figure 2 As shown, the dehumidification device 100 for thermal power plant equipment further includes a collection box 150 , which is detachably disposed on the base 110 and is located below the wet gas treatment assembly 130 .

[0057] It should be noted that the present embodiment does not specifically limit the connection method between the collection box 150 and the base 110 . For example, the collection box 150 may be fixed to the base 110 by a snap-fit ​​method.

[0058] In this embodiment, the collection box 150 can collect the condensed water after condensation of the cooling plate 132, and can also collect the dust after cleaning the sponge absorption plate 131. The collection box 150 is detachably connected to the base 110, and the collection box 150 can be easily removed to pour out the condensed water and dust inside.

[0059] For example, Figure 4 As shown, the dehumidification mechanism includes a fixing plate 121 , a blower 122 , a dehumidification pipe 123 and a plurality of air outlets 124 .

[0060] The fixing plate 121 is connected to the lifting driving mechanism, and the hair dryer 122 is disposed on the fixing plate 121 .

[0061] A plurality of air outlets 124 are arranged at intervals on the dehumidification tube 123 . The inlet of the dehumidification tube 123 is connected to the air outlet of the hair dryer 122 , and the outlet of the dehumidification tube 123 is connected to the air outlet 124 .

[0062] In this embodiment, the electric equipment can be dehumidified and cooled by the cooperation of the blower 122, the dehumidification tube 123 and the air outlet 124. The number of the air outlet 124 is not specifically limited in this embodiment and can be selected according to actual needs.

[0063] For example, Figure 4 As shown, the lifting drive mechanism includes a driving motor 125, a driving rod 126 and a lifting platform 127. The output shaft of the driving motor 125 is in transmission connection with the driving rod 126; the lifting platform 127 is disposed on the driving rod 126 and connected to the fixing plate 121.

[0064] Specifically, the driving motor 125 drives the driving rod 126 connected thereto to move up and down, thereby driving the lifting platform 127 to move up and down, and further driving the dehumidification mechanism located on the fixed plate 121 to move up and down.

[0065] It should be noted that the specific structure of the lifting drive mechanism is not limited in this embodiment, and it may also be other structures, such as a slide rail slider, a gear rack, etc., which can be selected according to actual needs.

[0066] For example, Figure 4 As shown, the lifting drive mechanism also includes a fixed frame 128 and a limit block 129, and the fixed frame 128 is provided with a driving rod 126 and a lifting platform 127. The limit blocks 129 are arranged on both sides of the lifting platform 127, and the inner side wall of the fixed frame 128 is provided with a limit groove 128a, and the limit block 129 corresponding to the limit groove 128a is slidably arranged in the limit groove 128a.

[0067] For example, Figure 1 and Figure 2 As shown, the dehumidification device 100 for thermal power plant equipment also includes a plurality of sliding wheels 160, and the sliding wheels 160 are arranged at the bottom of the base 110. The sliding wheels 160 can be universal wheels. The dehumidification device can be easily moved by the sliding wheels 160. There is no specific requirement for the number of sliding wheels 160, and it can be selected according to actual needs.

[0068] For example, Figure 1 and Figure 2 As shown, the dehumidification device 100 for thermal power plant equipment further includes a push rod 170 , which is disposed on the base 110 , so that an operator can push the dehumidification device to move.

[0069] It should be noted that, in this embodiment, the dehumidification device 100 for thermal power plant equipment can also be set up as multiple groups, which can be moved back and forth in appropriate areas of the thermal power plant, which can achieve a certain dehumidification effect inside the thermal power plant and reduce the impact of moisture on electrical equipment to a certain extent.
