DETAILED DESCRIPTION

[0024] 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.

[0025] See also Figures 1 to 5 The utility model provides a technical solution: a waterproof distribution network terminal main panel mechanism, including a door frame 7, the door frame 7 is sealed and installed at the opening of a cabinet 16, the cabinet 16 is an electric control device such as a distribution cabinet and a control cabinet, and the door frame 7 and the opening of the cabinet 16 can be directly welded and sealed, or fastened and sealed by bolts.

[0026] like Figure 1 As shown, a panel 5 is placed inside the door frame 7. The size of the panel 5 is just enough to seal the inner cavity of the door frame 7. One side of the panel 5 is rotatably connected to the door frame 7, and the two are specifically connected by a hinge. The other side of the panel 5 is connected to the door frame through a hidden lock 4. Figure 2 As shown, a current display meter and a voltage display meter are installed on the panel 5, and various switches are also provided, such as a closing switch, an opening switch, etc., and these switches and display meters need to be waterproof, otherwise rainwater will flow into the inside of the switch and it is easy to cause short circuit and electric shock problems.

[0027] A water retaining frame 6 is provided at the inner edge of the door frame 7 away from the cabinet body. The water retaining frame 6 surrounds the edge of the inner cavity of the door frame 7 and extends in a direction away from the cabinet body. The water retaining frame 6 is provided with a certain distance from the outer edge of the door frame 7.

[0028] A protective cover 1 is rotatably provided at the edge of the door frame 7, and the two are specifically connected by a hinge. The other side of the protective cover 1 is connected to the door frame by a lock. The opening of the protective cover 1 faces the panel 5. The protective cover 1 is rotated to cover the side of the door frame 7. At this time, the water retaining frame 6 is placed in the protective cover 1, and a certain distance is set between the side of the water retaining frame 6 and the side of the protective cover 1; Figure 1 As shown, the water retaining frame 6 is specifically provided to protect the edge of the panel, that is, the water retaining frame 6 forms a structure like an eave around the panel, and when the protective cover 1 is covered on the side of the door frame 7, a groove is formed between the water retaining frame 6 and the inner wall edge of the protective cover 1 (such as Figure 1 The groove can prevent rainwater from entering the water retaining frame 6, thus achieving a waterproof effect.

[0029] In order to further improve the sealing effect, such as Figure 1 and Figure 2 As shown, a sealing strip 3 whose position and size correspond to the water retaining frame 6 is provided on the inner cavity side of the protective cover 1. The sealing strip 3 is in elastic contact with the side of the water retaining frame 6. The gap between the water retaining frame 6 and the protective cover is sealed by the provided sealing strip, thereby further improving the waterproof effect.

[0030] The installation structure of the sealing strip 3 and the specific structure of the water retaining frame 6 will be specifically introduced below:

[0031] First, the sealing strip 3 is elastic and is specifically made of rubber. An opening 12 is provided in the middle of one side of the sealing strip 3 away from the water retaining frame 6. A flange accommodating cavity 13 is provided at the deepest part of the opening 12. The cross section of the flange accommodating cavity 13 is circular and its diameter is greater than the width of the opening 12.

[0032] An anti-drop flange 8 is provided in the flange accommodating cavity 13, and the anti-drop flange 8 is installed on the frame-shaped supporting edge 11, and the frame-shaped supporting edge 11 is placed in the opening 12 and installed on the inner cavity side of the protective cover 1. In actual use, the sealing strip is prone to aging, because the side of the sealing strip is provided with an opening 12 and a flange accommodating cavity 13, so that the sealing strip is detachable. When the sealing strip needs to be replaced, the specific operation process is to forcefully pull the old sealing strip out of the anti-drop flange 8, and then align the opening 12 of the new sealing strip with the anti-drop flange 8, and then forcefully press the anti-drop flange 8 into the flange accommodating cavity 13 to complete the installation of the sealing strip;

[0033] Secondly, the water retaining frame 6 includes a sealing frame 9, the sealing frame 9 is perpendicular to the surface of the door frame 7, the top of the sealing frame 9 is provided with an arc-shaped curved portion 14 bent outward, the top of the arc-shaped curved portion 14 is provided with a water retaining portion 15 extending toward the cabinet body, and the water retaining portion 15, the arc-shaped curved portion 14 and the sealing frame 9 constitute a water flow channel 18 (such as Figure 5 As shown), Figure 3 As shown, after the arc-shaped curved portion 14 contacts and seals with the sealing strip 3, if water enters the edge of the protective cover 1, the water will be blocked by the water flow groove 18 and will not flow into the water retaining frame 6. The water will flow downward along the water flow groove 18 and will eventually be discharged from the water flow hole 17 at the bottom of the inner cavity of the protective cover 1.

[0034] Further, such as Figure 3 and Figure 4 As shown, a compression chamber 10 is provided inside the sealing strip 3 near the arc-shaped curved portion 14. When the protective cover 1 is covered on the side of the door frame 7, the arc-shaped curved portion 14 contacts the side of the sealing strip 3, and the arc-shaped curved portion 14 squeezes the side of the sealing strip 3 and deforms toward the compression chamber 10, as shown in FIG. Figure 3 As shown, the compression chamber 10 provided can increase the deformation degree of the side surface of the sealing strip 3, thereby increasing the contact area between the side surface of the sealing strip 3 and the arc-shaped curved portion 14, so as to achieve a better sealing effect. At the same time, it also increases the elastic strength of the side surface of the sealing strip, allowing it to contact more closely with the arc-shaped curved portion 14.

[0035] Based on the above embodiment, further optimization can be performed, such as Figure 1 and Figure 2 As shown, a transparent window 2 is provided on the protective cover 1 inside the sealing strip 3, and a transparent plate is sealed and installed inside the transparent window 2. The transparent plate is a transparent plastic plate or transparent glass. The degree of the instrument on the panel can be directly observed through the transparent window.
