DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-5 As shown, a hot air boiler control cabinet that is easy to maintain includes a shell 1 with an installation cavity 103, a cabinet door 2 hinged on the front side of the shell 1, and a mounting plate 3. The left and right sides of the installation cavity 103 are welded with upper and lower pulley frames 4, and the pulley frames 4 on the left and right sides of the installation cavity 103 are symmetrically arranged. The left and right sides of the installation plate 3 are provided with pulleys 7 sliding in the pulley frames 4. The side of the pulley 7 close to the installation plate 3 is rotatably connected to a connecting column 6 welded to the installation plate 3 through a bearing. Two hinge seats 10 located between the upper and lower pulley frames 4 are welded on the front side of the installation plate 3. The side of the hinge seat 10 away from the installation plate 3 is hinged with a spare parts frame 5;

[0023] The rear side of the installation cavity 103 is provided with a driving assembly connected to the installation plate 3 to drive the installation plate 3 to slide forward and backward.

[0024] During use, the staff can install the electrical components to the front side of the mounting plate 3 by bolts, and then the mounting plate 3 can slide back and forth in the mounting cavity 103 under the drive of the driving component. When the electrical components in the control cabinet need to be repaired, the staff can control the driving component to move the mounting plate 3 to the front end of the mounting cavity 103, and the spare parts rack 5 moves with the movement of the mounting plate 3 in the mounting cavity 103. When the mounting plate 3 moves to the front end of the mounting cavity 103, the spare parts rack 5 is located outside the mounting cavity 103. The staff can rotate the spare parts rack 5 to both sides of the maintenance personnel, which is convenient for the maintenance personnel to take the spare parts and improve the work efficiency of the maintenance personnel during maintenance.

[0025] In this embodiment, the driving assembly includes an electric push rod 8 fixed to the rear side of the mounting cavity 103 by bolts, and the output shaft of the electric push rod 8 is connected to the rear side of the mounting plate 3. When in use, the staff can control the extension and retraction of the output shaft of the electric push rod 8, and then control the movement of the mounting plate 3 in the mounting cavity 103, so as to facilitate the staff to adjust the position of the mounting plate 3 in the mounting cavity 103.

[0026] In this embodiment, four layers of spare parts areas 501 are arranged in the spare parts rack 5, and each layer of spare parts area 501 is provided with a placement slot, and the placement slot is connected to the opposite sides of the left and right spare parts racks 5. When in use, the staff can place the electrical component spare parts in the placement slot, and classify the electrical component spare parts and place them in different spare parts areas 501 to facilitate the staff to take them.

[0027] In this embodiment, an exhaust port 102 is provided on the lower side of the shell 1, and an exhaust fan 11 located on the lower side of the installation cavity 103 is inserted into the exhaust port 102. The exhaust fan 11 is fixed to the lower side of the installation cavity 103 by bolts. The shell 1 is provided with a plurality of ventilation holes 101 located on the upper ends of the left and right sides, and the ventilation holes 101 are connected to the installation cavity 103. When in use, the exhaust fan 11 can exhaust the air in the installation cavity 103 out of the shell 1, and speed up the air circulation in the installation cavity 103 through the ventilation holes 101, thereby reducing the temperature of the electrical components and increasing the service life of the electrical components.

[0028] In this embodiment, magnets 12 that fit the inner wall of the shell 1 are glued to the opposite sides of the two spare parts racks 5. When in use, the spare parts racks 5 can be adsorbed on the inner wall of the shell 1 through the magnets 12 to prevent the spare parts racks 5 from rotating in the installation cavity 103 and causing damage to the electrical components.

[0029] In this embodiment, a lighting device 9 is fixed to the upper side of the installation cavity 103 by bolts. The lighting device 9 is a common lighting device such as an LED lamp. When in use, the lighting device 9 can provide light for the staff during maintenance, thereby reducing the danger to the staff during maintenance.

[0030] In this embodiment, an observation window 201 and a handle 202 are provided on the front side of the cabinet door 2. A transparent glass plate is glued inside the observation window 201.
