Description

Technical Field

[0001] The utility model relates to the technical field of electric control box equipment, in particular to a high temperature monitoring device for an electric control box of a medium voltage electric energy transmission system. Background Art

[0002] A medium voltage power transmission system refers to a power transmission system used to transmit electric energy. Its voltage level is between low voltage and high voltage, usually between 1 kV and 36 kV. Medium voltage systems are often used in cities, industrial areas or long-distance power transmission applications. They can not only meet the power supply reliability requirements, but also control the transmission costs. When in use, they are generally used with an electric control box. The electric control box is equipped with various components with different properties, and most of them are high-precision semiconductor components. The requirements for the working environment are very high. The components themselves heat up very seriously during the working process. If these components cannot be cooled in time, it is easy to cause damage to the components, affecting the normal working efficiency, and even posing a greater safety hazard. Therefore, a high temperature monitoring device is used to monitor the temperature inside the electric control box to prevent danger.

[0003] The high temperature monitoring device of the electric control box in the prior art is generally composed of a temperature sensor, a processor, a controller, a cooling fan, etc. The temperature inside the electric control box is monitored by using a temperature sensor, and the monitoring information is transmitted to the processor. When the temperature is high, the processor will send a start instruction to the controller, so that the controller can control the cooling fan to dissipate heat inside the electric control box, thereby ensuring the safety of use and the service life of the electric control box.

[0004] However, in actual use, a dust cover is generally installed on the outside of the cooling fan with bolts to prevent dust from entering the interior of the electric control box. However, after the dust cover has been used for a long time, dust and other impurities will adhere to the outside of the dust cover, which will then block the apertures of the dust cover, thereby affecting the heat dissipation effect, so that the electric control box cannot be effectively cooled in time, which will still affect the service life of the electric control box.

[0026] A temperature sensor, a processor, a controller, a cooling fan, etc. are installed inside the box 1. The temperature inside the box 1 is monitored by using the temperature sensor, so that the monitoring information is transmitted to the processor. When the temperature is high, the processor will send a start command to the controller, so that the controller can control the cooling fan to dissipate the heat inside the box 1, thereby ensuring the safety and service life of the box 1. The slide groove 3 limits the internal slider 7, and the mounting frame 2 limits the internal mounting block 10, so that the mounting block 10 will not be offset when moving. When it is necessary to clean the outside of the connecting rod 6, by pulling the mounting block 10, the mounting block 10 can drive the push rod 14 to move, and then the push rod 14 can drive the cleaning brush 16 to clean the outer surface of the dust cover 5, so that dust will not block the through hole of the dust cover 5, and then during heat dissipation, the outside air can enter the interior of the electric control box in time, so that the electric control box can be timely cooled, so that the service life of the electric control box will not be reduced, and the effect of effective protection is achieved, so that the use economy of the high temperature monitoring device of the electric control box is high.

[0027] Embodiment 2

[0028] On the basis of Example 1, in order to increase the service life and cleaning effect of the cleaning brush 16, a placement groove 11 is opened inside the mounting block 10, and the outside of the mounting block 10 is slidably connected to the inner side of the mounting frame 2. An elastic sheet 12 is fixedly connected to the upper side of the inner wall of the placement groove 11. The elastic sheet 12 has multiple "V"-shaped designs, and the bottom end of the elastic sheet 12 is fixedly connected to a connecting plate 13. Multiple push rods 14 are fixedly connected to the bottom end of the connecting plate 13, and the outside of the connecting plate 13 is slidably connected to the inside of the elastic sheet 12.

[0029] When the cleaning brush 16 is installed, the cleaning brush 16 can push the push rod 14 to move upward, and then the push rod 14 can push the connecting plate 13 to move upward, so that the connecting plate 13 can squeeze the elastic sheet 12 to deform. At this time, the cleaning brush 16 is released, and the elastic sheet 12 can continue to make a reset movement, so that the elastic sheet 12 can push the connecting plate 13 to move downward, so that the connecting plate 13 can push the cleaning brush 16 through the push rod 14 to fit closely with the surface of the dust cover 5, thereby improving the cleaning effect of the cleaning brush 16 on the surface of the mounting frame 2, and when the cleaning brush 16 is worn, the elastic sheet 12 can push the cleaning brush 16 to maintain a fit with the dust cover 5, thereby increasing the service life of the cleaning brush 16.

[0030] Embodiment 3

[0031] On the basis of the second embodiment, a sub-belt 17 is provided at the top of the cleaning brush 16 , a mounting plate 15 is installed at the top of the sub-belt 17 , and the bottom ends of the plurality of push rods 14 are fixedly connected to the top of the mounting plate 15 .

[0032] When the cleaning brush 16 needs to be replaced, the cleaning brush 16 can be disassembled by separating the sub-tape 17 between the mounting plate 15 and the cleaning brush 16, and then the new cleaning brush 16 is connected to the mounting plate 15 through the sub-tape 17, so that the cleaning brush 16 can be conveniently installed, making the replacement efficiency of the cleaning brush 16 higher, thereby reducing the labor cost.

[0033] Embodiment 4

[0034] On the basis of Example 3, the front and rear sides of the mounting frame 2 are hinged with connecting rods 6, and the bottom end of the connecting rod 6 is fixedly connected to a slider 7. Four slide grooves 3 are opened on the top of the box body 1. The slide grooves 3 are arc-shaped grooves and "T"-shaped grooves. The slide grooves 3 are adapted to the connecting rods 6. The outside of the connecting rod 6 is slidably connected to the inner middle part of the slide groove 3, and the outside of the slider 7 is slidably connected to the inner outer side of the slide groove 3. The inside of the slide groove 3 is fixedly connected to a rubber block 4, and the rubber block 4 fits the connecting rod 6.

[0035] When the cleaning brush 16 cannot effectively clean the dust cover 5 and the dust cover 5 needs to be replaced, the connecting rod 6 is rotated outward so that the connecting rod 6 and the slider 7 can slide outward in the inside of the slide groove 3. At the same time, the connecting rod 6 can squeeze the rubber block 4 to produce deformation, so that the rubber block 4 no longer restricts the position of the connecting rod 6, and then the connecting rod 6 can be detached from the inside of the slide groove 3. At this time, the dust cover 5 can be conveniently removed by pulling the dust cover 5 upward. When a new dust cover 5 needs to be installed, the dust cover 5 is sleeved on the cooling fan and the connecting rod 6 is slid into the inside of the slide groove 3, so that the connecting rod 6 can squeeze the rubber block 4 to produce deformation. When the inner side of the connecting rod 6 is in contact with the inner wall of the slide groove 3, the connecting rod 6 no longer squeezes the rubber block 4. At this time, the rubber block 4 can perform a reset movement, so that the rubber block 4 can limit the position of the connecting rod 6, and then the connecting rod 6 will not deviate without the action of external force, so that the dust cover 5 can be stably installed in the inside of the box body 1.

[0036] In actual use, by pulling the mounting block 10, the mounting block 10 can drive the push rod 14 to move, and then the push rod 14 can drive the mounting plate 15 to move, so that the mounting plate 15 can drive the cleaning brush 16 to clean the surface of the dust cover 5, so that dust will not block the through holes of the dust cover 5, so that when heat is dissipated, the external air can enter the interior of the electric control box in time, so that the electric control box can be cooled in time, and the service life of the electric control box will not be reduced, so as to achieve the effect of effective protection, and the use economy of the high temperature monitoring device of the electric control box is higher.
