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] See also Figure 1-Figure 5The utility model provides an embodiment: a waterproof meter box, comprising a meter box body 1 for placing and protecting a plurality of meters, and meter boxes 2 (for placing meters, the number of which can be six or eight, etc., arranged and assembled according to actual conditions) are equidistantly embedded inside the meter box body 1, and a transparent protective plate 3 (the material can be plastic or glass, which is convenient for observing the internal conditions) can be hinged on the outer side wall of the meter box 2, and a sealing device is provided between the transparent protective plate 3 and the meter box 2 (which can be a sealing strip with a sealing groove, etc., to ensure the sealing effect when closed, to play a role of waterproof and dustproof, to ensure the safety of use, a relatively mature technology, and will not be repeated here), and in order to achieve better ventilation and drying effects during work, a sealing device is provided on the side wall of the meter box body 1. There is a heat dissipation through hole 7 with a ventilation and drying component, and a dustproof net can be arranged inside it to prevent external dust from entering the interior. A drying box 8 is arranged on one side of the heat dissipation through hole 7 located inside the meter case 1. The drying box 8 is provided with a filling hole 9 connected to the heat dissipation through hole 7 (it is filled with desiccant to facilitate drying of the air and ensure that the inside of the meter case 1 is in a relatively dry environment). In order to facilitate the observation of the use of the desiccant, a color-changing silica gel 10 is embedded in the middle of the drying box 8, and the drying condition can be judged by the color of the color-changing silica gel 10 (a relatively mature technology, which will not be described here). The inside of the meter case 1 can also be equipped with a heat dissipation device (which can be a heat dissipation fan, etc.) compatible with the heat dissipation through hole 7 according to actual conditions, so that ventilation and heat dissipation can be carried out when the meter is working, and heat exchange with the outside world is carried out.

[0023] See also Figure 1-Figure 5 In order to facilitate wiring during assembly, reserved holes 11 are equidistantly provided at the bottom of the meter box 1 (the number can be three or four groups, one reserved hole 11 is suitable for two groups of meters, or six or eight groups can be provided, one-to-one, according to actual conditions). The position of the reserved hole 11 can also be provided on the side wall, the rear end or the top end according to actual installation conditions. A certain length of the wire is reserved to ensure normal use while not affecting the lifting operation of the meter box 1. An elastic sealing pad 12 is bonded in the reserved hole 11, which can be conveniently sealed after wiring to prevent external moisture and dust from entering the interior. In order to prevent the wire from being entangled during use and lifting, support rods 13 are equidistantly welded inside the meter box 1. Guide rings 14 corresponding to the reserved holes 11 are welded at the ends of the support rods 13, which can guide and limit the wires, and a rubber ring 15 is bonded to the inner wall (it can avoid hard contact with the wires, and its material is insulating rubber material to ensure safety in use).

[0024] See also Figure 1-Figure 5In order to facilitate the staff to read meters, perform maintenance and other operations, and to facilitate direct operation without standing on tiptoe or using tools such as stools to improve safety and comfort, a mounting plate 4 is provided on the meter box 1, and a placement cavity 22 is provided inside the mounting plate 4. A motor 21 of a winding mechanism is installed inside the placement cavity 22. The output end of the motor 21 is fixedly installed with a rotating shaft 19 through a coupling, and two sets of rope reels 20 are provided outside the rotating shaft 19. A connecting rope 16 is wound on the rope reel 20, and its end passes through the placement cavity 22 and is provided with a connecting ring 17. The connecting ring 17 is welded and fixed to the top of the meter box 1 In order to ensure the stability of the up and down lifting process and prevent shaking, the two sides of the bottom end of the mounting plate 4 are vertically welded with a card plate 5 of a sliding assembly, and a rectangular guide groove 18 is opened on the inner wall of the card plate 5 (the number of guide grooves 18 on one card plate 5 can be two groups), and a guide plate 6 is welded on the side wall of the meter box 1 for convenient up and down sliding in the guide groove 18. The up and down lifting height can be 30-60cm, and can also be adjusted according to actual conditions, so that the staff can read the meter, regularly inspect and maintain the meter at a high place, which is more convenient and does not need to tiptoe or use tools to complete the work.

[0025] Working principle: When the utility model is in use, during assembly and wiring, the wire can be routed through the reserved hole 11, and then the wire can be guided and limited through the guide ring 14 to avoid the adjacent guides from being entangled during subsequent use or lifting, which is convenient for subsequent maintenance operations. The elastic sealing pad 12 can seal the reserved hole 11 after assembly to prevent external moisture and dust from entering the interior. When in use, the heat dissipation through hole 7 can facilitate air flow, and then the desiccant in the filling hole 9 on the drying box 8 is dried to accelerate air flow, play a role in ventilation and heat dissipation, and at the same time prevent external moisture from entering the interior, ensuring Safety, and when inspection, maintenance and other operations are required, the motor 21 rotates forward, driving the shaft 19 to rotate, and then the rope reel 20 rotates to pay out the connecting rope 16, and then the meter box 1 moves downward with its own gravity, and the guide plate 6 slides in the guide groove 18 to limit the position to avoid deviation and shaking. After descending to a suitable height, the staff can read the meter, inspect or maintain it, which is more convenient and does not require tiptoeing or using tools to operate the high meter. After the operation is completed, the motor 21 can be rotated in the reverse direction, and the rope reel 20 can be rotated to reel in the connecting rope 16, and the meter box 1 can be moved up and reset.
