DETAILED DESCRIPTION

[0021] Example 1

[0022] like Figure 1 Figure 2 Figure 3As shown, this embodiment provides a mobile monitoring device for a UHV substation with an alarm function, which includes an inspection vehicle 100, the inspection vehicle 100 includes a base 210, and a base cavity 220 is provided in the base 210; the inspection vehicle 100 also includes a protective shell 110 arranged at the base 210, the protective shell 110 includes an inner shell 230 covering the base cavity 220 and an outer shell 240 arranged outside the inner shell 230, and a connecting channel 250 is formed between the inner shell 230 and the outer shell 240; the outer shell 240 and the inner shell 230 are connected to each other. 0, an observation port 120 is provided at the observation port 120, and a glass sealing cover 130 is provided at the observation port 120; a mounting bracket 260 is provided in the inner shell 230, and an infrared camera and a visible light camera facing the glass sealing cover 130 are provided at the mounting bracket 260; an air intake channel 270 and an exhaust channel 280 connected to both ends of the connecting channel 250 are also provided in the base 210, and an exhaust port 290 connected to the exhaust channel 280 is provided at the base 210; an air intake mechanism for heating the outside air and sending it into the air intake channel 270 is also provided in the base 210. Among them, the air intake mechanism includes a heating chamber 2100 connected to the air intake channel 270, an electric heating wire 2110 is provided in the heating chamber 2100, an air intake hole 2120 connected to the heating chamber 2100 is provided at the side wall of the base 210, a fan 2130 covering the air intake hole 2120 and used to send external air into the heating chamber 2100 is provided at the base 210, and an outer cover 160 covering the fan 2130 is provided at the outer wall of the inspection vehicle 100.

[0023] When in use, the inspection vehicle 100 is placed in the substation and moved, and the equipment in the substation is monitored by the infrared camera and the visible light camera. When encountering bad weather, such as ice and snow weather, the fan 2130 and the electric heating wire 2110 are started, so that the outside air enters from the air inlet 2120 and is heated by the electric heating wire 2110 of the heating chamber 2100. The heated air is discharged from the exhaust port 290 through the air inlet channel 270, the connecting channel 250 and the exhaust channel 280. The specific working principle is as follows: Figure 7 As shown, when the hot air passes through the connecting channel 250, the glass sealing cover 130 at the outer shell 240 and the inner shell 230 is heated, thereby preventing the glass sealing cover 130 from fogging or frosting, thereby ensuring that the ultra-high voltage substation mobile monitoring equipment with an alarm function can operate stably in a harsh environment, thereby better improving the effect of monitoring the substation equipment. At the same time, by discharging the hot air from the exhaust port 290, the exhaust port 290 is set at the bottom of the inspection vehicle 100, the ground of the substation can be heated, thereby avoiding snow or ice in the substation, and further improving the stability of the equipment in the substation.

[0024] The UHV substation mobile monitoring equipment with an alarm function in this embodiment can heat the glass sealing covers 130 at the infrared camera and the visible light camera in snowy weather through the arrangement of the electric heating wire 2110, the air inlet channel 270, the connecting channel 250 and the exhaust channel 280, thereby avoiding fogging or frosting of the glass sealing cover 130. This allows the UHV substation mobile monitoring equipment with an alarm function to operate stably in severe weather, thereby greatly improving the monitoring effect of the equipment in the substation.

[0025] The base 210 is provided with a filter cotton installation cavity 2140 located between the air inlet hole 2120 and the heating cavity 2100 . The filter cotton installation cavity 2140 is communicated with the heating cavity 2100 . A filter cotton plate 2150 is provided in the filter cotton installation cavity 2140 .

[0026] By setting the filter cotton plate 2150, the air entering the heating chamber 2100 can be filtered, thereby preventing dust in the outside air from entering the base cavity 220 and polluting the electrical components in the base cavity 220, thereby better improving the stability of the ultra-high voltage substation mobile monitoring equipment with alarm function.

[0027] Combination Figure 4 , Figure 5As shown, the base 210 of the base 210 is also provided with a bottom plate 2160, and a transition cavity 2170 communicating with the heating cavity 2100 and the air inlet channel 270 is formed between the bottom plate 2160 and the bottom end surface of the base cavity 220, and a cavity air inlet 2180 is provided at the bottom end surface of the base cavity 220, and a baffle 2190 capable of blocking the cavity air inlet 2180 and the air inlet channel 270 is slidably provided in the base 210, and a baffle first opening 2200 located at the cavity air inlet 2180 and a baffle located at the air inlet channel 270 are provided at the baffle 2190. The second opening 2210 of the plate; a driving mechanism is provided in the transition cavity 2170 for driving the baffle plate 2190 to slide so as to block one of the cavity air inlet 2180 and the air inlet channel 270; a strip through hole 2220 is provided at the upper end of the inner shell 230 for discharging the air in the base cavity 220, and a vertical plate 2230 located in the exhaust channel 280 is provided at the baffle plate 2190, and the vertical plate 2230 can move with the baffle plate 2190 and can block the strip through hole 2220 when the baffle plate 2190 blocks the cavity air inlet 2180. The driving mechanism includes a group of first strip plates 510 arranged at the bottom plate 2160, a screw rod 520 is rotatably provided at the first strip plate 510, and a strip plate air inlet 570 is also provided at the first strip plate 510; the driving mechanism also includes a second strip plate 560 arranged at the bottom plate 2160 and used to seal the side end opening of the transition chamber 2170; a screw rod slide 530 connected to the baffle 2190 is provided at the screw rod 520, a reduction box 540 is provided at the side wall of the base 210, the output shaft of the reduction box 540 is connected to the screw rod 520, and the input shaft of the reduction box 540 is connected to the motor 550.

[0028] In hot seasons such as summer, the electrical components in the base cavity 220 tend to generate a lot of heat when working for a long time. The heat accumulates in the base cavity 220 and cannot be discharged well, which tends to accelerate the aging or failure of the electrical components in the base cavity 220. The first baffle opening 2200 at the baffle 2190 is moved to the cavity air inlet 2180 through the driving mechanism; the second baffle opening 2210 at the baffle 2190 is moved to be misaligned with the air inlet channel 270 to block the air inlet channel 270, and at this time, the vertical plate 2230 moves to be separated from the blocking of the bar-shaped through hole 2220. The fan 2130 is started and the electric heating wire 2110 is not started, so that the outside air enters the base cavity 220 through the air inlet 2120, the heating cavity 2100, the transition cavity 2170, the first opening 2200 of the baffle plate and the cavity air inlet 2180 in sequence, and is discharged from the exhaust port 290 through the strip through hole 2220 and the exhaust channel 280. The specific working principle is as follows: Figure 8 As shown, the heat generated by the electrical components in the base cavity 220 during operation is discharged.

[0029] Among them, the setting of the first strip plate 510 not only provides a mounting structure for the screw rod 520, but also can form an installation for the baffle 2190 together with the bottom end surface of the base 210; the setting of the second strip plate 560 not only provides a mounting structure for the screw rod 520, but also can form an installation for the baffle 2190 together with the bottom end surface of the base 210, and can also seal the side end opening of the transition chamber 2170, so that outside air can enter the base cavity 220.

[0030] In this embodiment, through the cooperation between the baffle 2190 and the driving mechanism, the heat generated by the electrical components in the base cavity 220 during operation can be discharged, thereby avoiding the accumulation of heat in the base cavity 220 and the inability to discharge heat well, which accelerates the aging or failure of the electrical components in the base cavity 220, thereby further improving the stability of the ultra-high voltage substation mobile monitoring equipment with alarm function.

[0031] Combination Figure 6 As shown, a partition 610 is provided in the base cavity 220, and the partition 610 divides the base cavity 220 into an equipment installation cavity 620 and a battery installation cavity 630. There are two cavity air inlets 2180, which are respectively arranged at the bottom wall of the equipment installation cavity 620 and the bottom wall of the battery installation cavity 630. A battery exchange port 140 communicating with the battery installation cavity 630 is provided at the side wall of the inspection vehicle 100, and a sealing door 150 is provided at the battery exchange port 140.

[0032] By setting the partition 610, the base cavity 220 can be divided into a device installation cavity 620 and a battery installation cavity 630, thereby facilitating the installation of batteries and electrical components. By setting the sealing door 150, it is convenient for staff to replace batteries.
