[0020] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0021] The present invention proposes an alarm device for thermal control of a thermal power plant. Figure 1 and Figure 2 Elaborate in detail.

[0022] An alarm device for thermal control in a thermal power plant comprises a box body 1, a group of opposite side walls of the box body 1 are provided with a plurality of heat dissipation holes 3, a dust removal controller 4 is provided in the box body 1, an air supply plate is provided between the dust removal controller 4 and the heat dissipation holes 3, a plurality of dust removal nozzles 42 are provided on a side wall of the air supply plate opposite to the heat dissipation holes 3, the dust removal nozzles 42 are electrically connected to the dust removal controller 4, and the dust removal controller 4 is electrically connected to a wind source component 43 for supplying air to the dust removal nozzles 42. In one embodiment, the wind source component 43 is configured as a micro fan, a ventilation duct is provided inside the air supply plate, the ventilation duct is connected to each dust removal nozzle 42, and the ventilation duct is connected to a pipeline of the wind source component 43.

[0023] The present invention provides a dust removal nozzle 42 and a dust removal controller 4, so that the staff can manually control the dust removal operation of the dust removal nozzle 42 through the dust removal controller 4, or preset a timed cleaning time in the dust removal controller 4. When the preset time is reached, the dust removal controller 4 controls the dust removal nozzle 42 to blow air toward the heat dissipation hole 3, thereby blowing the dust in the heat dissipation hole 3 out of the box 1 to complete the dust removal operation.

[0024] In some embodiments, each dust removal nozzle is provided corresponding to a heat dissipation hole 3, so as to ensure that the airflow can be stably blown directly into the heat dissipation hole 3, and the airflow is turned back after hitting the hole wall of the heat dissipation hole 3, so as to clean the dust accumulated in the heat dissipation hole 3.

[0025] In some embodiments, in order to facilitate the fixing of the dust removal controller 4, a fixing bracket 5 for fixing the dust removal controller 4 is provided on the inner wall of the box body 1. The fixing bracket 5 is arranged on a side wall of the box body 1 perpendicular to the side wall without the heat dissipation hole 3, so as to avoid the dust removal controller 4 blocking the heat dissipation of the heat dissipation hole 3. The fixing bracket 5 is arranged between two air supply plates, which reduces the wire connection distance between the dust removal controller 4 and each dust removal jet head 42 on the air supply plate.

[0026] In some embodiments, the heat dissipation holes 3 are all arranged at an angle, and the height of each heat dissipation hole 3 facing the inner side of the box body 1 is higher than the height of the heat dissipation hole 3 facing the outer side of the box body 1. The heat dissipation holes 3 arranged at an angle can effectively prevent dust from the external environment of the box body 1 from entering the heat dissipation holes 3 and dust from accumulating in the heat dissipation holes 3.

[0027] In some embodiments, a dustproof net 6 is disposed outside each heat dissipation hole 3. The dustproof net 6 can further isolate dust in the external environment.

[0028] In some embodiments, a dust concentration sensor 10 is provided at the top of the box 1, and the dust concentration sensor 10 is electrically connected to the dust removal controller 4, and an alarm 11 electrically connected to the dust removal controller 4 is provided on the top wall of the box 1. The dust concentration sensor 10 can detect the dust concentration in the environment. When it is detected that the dust concentration reaches the threshold, the alarm 11 sounds an alarm to remind the staff to check the working environment and find out the reason for the excessive increase in the amount of dust. At the same time, after receiving the signal from the dust concentration sensor 10, the dust removal controller 4 will control the wind source 43 to supply air and the dust removal nozzle 42 to spray, so as to ensure that the air in the heat dissipation hole 3 is circulated to the outside, thereby preventing the high-concentration dust air outside the box 1 from entering the box 1 to generate dust accumulation.

[0029] In some embodiments, a fixing ear 9 for fixing the box body 1 is provided on the top of the box body 1. The provision of the fixing ear 9 can facilitate the staff to install and fix the alarm device in various working conditions.

[0030] In some embodiments, a thermal insulation layer 2 is provided on the inner wall of the box body 1, and the heat dissipation holes 3 are provided through the thermal insulation layer 2. The provision of the thermal insulation layer 2 can reduce the impact of external high temperature conditions on the components in the box body 1.

[0031] In some embodiments, a display screen 8 and a plurality of control keys 7 are provided on the box body 1. The display screen 8 and the control keys 7 can facilitate the staff to set the dust removal controller 4 at a fixed time, and the display screen 8 can display the data of the controller set in the alarm device for detecting other data of the environmental working condition, so as to facilitate the staff to obtain the environmental working condition data information in a timely manner.

[0032] In some embodiments, the dust removal controller 4 includes a timing unit. The timing unit can be set to meet the purpose of setting a scheduled cleaning by the staff. After the staff inputs the scheduled cleaning time to the dust removal controller 4, the timing unit starts working. When the preset time is reached, the timing unit sends an action signal to the dust removal controller 4, and the dust removal controller 4 controls the wind source 43 to supply air and the dust removal nozzle 42 to open, thereby performing a scheduled cleaning operation.
