[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-6 This utility model provides a technical solution: a well heat dissipation control metering box, including a metering box body 1, and a protective mechanism for protecting internal components is provided on the metering box body 1. The protective mechanism includes:

[0027] The rainproof assembly includes a V-shaped first rainproof shell 2 fixed to the upper end of the metering box body 1, a rainproof plate 202 fixed to the front edge of the upper end of the metering box body 1, and a second rainproof shell 203 fixed to the upper end of the rainproof plate 202.

[0028] The heat dissipation assembly includes a ventilation housing 3 fixed on both sides of the metering box body 1. A sliding housing 301 is fixed on the side wall of the ventilation housing 3. A filter support 302 is slidably connected inside the sliding housing 301. A locking assembly for disassembly is provided at the upper end of the filter support 302. A connecting shaft 502 is rotatably connected to the inner wall of the ventilation housing 3. An air guide plate 503 is fixed on the outer wall of the connecting shaft 502. A gear assembly for adjustment is provided at one end of the connecting shaft 502.

[0029] In a preferred embodiment, the upper surface of the first rainproof shell 2 is uniformly provided with a first drainage groove 201, and the second rainproof shell 203 has a V-shaped structure and is located at the upper end of the cabinet door of the metering box body 1. The upper end of the second rainproof shell 203 is provided with a second drainage groove 204. When rainwater falls on the first rainproof shell 2, it will be drained to both sides along the first drainage groove 201. The rainwater falling on the second rainproof shell 203 will be drained along the second drainage groove 204. The second rainproof shell 203 is located at the upper end of the cabinet door of the metering box body 1, which can provide targeted protection for the cabinet door and prevent rainwater from seeping into the interior of the metering box body 1 from the gaps in the cabinet door. The V-shaped first rainproof shell 2 and the second rainproof shell 203 use their special shapes to make rainwater slide off quickly and prevent rainwater from accumulating.

[0030] The design of the first rainproof shell 2 and the second rainproof shell 203, along with the drainage channels, can effectively and comprehensively prevent rainwater from entering the metering box body 1, protecting the electronic components and equipment inside the box from rainwater corrosion, extending the service life of the equipment, and improving the stability and reliability of the metering box in rainy weather. The first drainage channel 201 and the second drainage channel 204 can quickly drain rainwater, preventing rainwater from accumulating on the rainproof shell and further improving the rainproof effect.

[0031] In a preferred embodiment, the engaging assembly includes a limiting shell 401 fixed to the upper end of the sliding shell 301, a spring 402 fixed to the inner wall of the limiting shell 401, a sliding plate 403 slidably connected to the inner wall of the limiting shell 401 fixed to the other end of the spring 402, a locking block 404 fixed to the side wall of the sliding plate 403, and a locking groove 4 for engaging with the locking block 404 on the top side wall of the filter support 302. The filter support 302 is slidably inserted into the sliding shell 301. During insertion, the sliding plate 403 is pulled along the spring 402 and compressed inside the limiting shell 401 by a pull rod. When the locking groove 4 and the locking block 404 are aligned, the spring 402 returns to its original position, pushing the sliding plate 403 and the locking block 404 into the locking groove 4, thus fixing the filter support 302. When disassembling, the locking block 404 is pulled to disengage from the locking groove 4, and the filter support 302 can be pulled out from the sliding shell 301.

[0032] The design of the snap-fit ​​component makes the disassembly and installation of the filter support 302 very convenient, without the need for complicated tools, which greatly improves maintenance efficiency. When the filter needs to be cleaned or replaced, the operation can be completed quickly, reducing downtime. In addition, the filter support 302 ensures the dustproof effect at the ventilation port of the ventilation housing 3, preventing dust from entering the interior of the metering box body 1.

[0033] In a preferred embodiment, a fixing plate 5 is fixed inside the ventilation housing 3, and a pair of cooling fans 501 are provided inside the fixing plate 5. The gear assembly includes a pair of horizontal plates 505 fixed to the inner wall of the ventilation housing 3. A gear rod 508 connected by a reciprocating assembly is provided inside the horizontal plate 505. A transmission gear 504 meshing with the gear rod 508 is fixed at one end of the connecting shaft 502. The reciprocating assembly includes a reciprocating screw 509 rotatably connected to the inner wall of the horizontal plate 505. A slide rod 506 is fixed to one side of the reciprocating screw 509 on the inner wall of the horizontal plate 505. A slider 507 is slidably connected to the outer wall of the slide rod 506, and the slider 507 is threadedly connected to the reciprocating screw 509. The gear rod 508 is fixedly connected to one side wall of the slider 507. When the pair of cooling fans 501 inside the fixing plate 5 are activated, the airflow inside the metering box body 1 is accelerated, and the internal components are cooled by blowing air.

[0034] The reciprocating screw 509 rotates under the drive of a micro motor. Since the slider 507 is threadedly connected to the reciprocating screw 509 and slidably connected to the slide rod 506, the slider 507 will perform reciprocating linear motion under the action of the reciprocating screw 509 and the slide rod 506. The gear rod 508 is fixed to one side wall of the slider 507 and will perform reciprocating linear motion together with the slider 507. The transmission gear 504 fixed at one end of the connecting shaft 502 meshes with the gear rod 508. When the gear rod 508 performs reciprocating linear motion, it will drive the transmission gear 504 to rotate alternately in both directions, thereby causing the connecting shaft 502 to drive the air guide plate 503 to rotate alternately in both directions, realizing the adjustment of the angle of the air guide plate 503, thereby changing the direction and range of the heat dissipation air.

[0035] Through the cooperation of the reciprocating components and gear components, the air guide plate 503 can automatically adjust its angle to evenly blow the cooling air generated by the cooling fan 501 to various parts inside the metering box body 1, avoiding the formation of heat dissipation dead zones, improving heat dissipation efficiency and effect, and ensuring that the electrical components inside the metering box body 1 operate at a suitable temperature.

[0036] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0037] During operation, when it rains, rainwater falling on the V-shaped first rainproof shell 2 will be quickly drained to both sides along the first drainage channel 201. Rainwater falling on the V-shaped second rainproof shell 203 located at the top of the cabinet door of the metering box body 1 will be drained along the second drainage channel 204. Its special shape allows rainwater to slide off quickly, avoiding accumulation and effectively preventing rainwater from seeping into the interior of the metering box body 1 from the gaps in the cabinet door, thus achieving rain protection for the components inside the box.

[0038] When the filter support 302 needs to be installed, it is slid into the inner side of the slide groove housing 301. During the insertion process, pulling the lever causes the slide plate 403 to compress inside the limiting housing 401 along the spring 402. When the slot 4 at the top of the filter support 302 aligns with the locking block 404, the spring 402 returns to its original position, pushing the slide plate 403 and the locking block 404 into the slot 4 to complete the fixing. To disassemble, pull the locking block 404 to disengage it from the slot 4, and the filter support 302 can be pulled out for easy cleaning or replacement of the filter. When the pair of cooling fans 501 inside the fixing plate 5 are activated, their acceleration inside the metering box body 1... Airflow is used to dissipate heat from the components. At the same time, a micro motor drives a reciprocating screw 509 to rotate. The slider 507, which is threaded to the reciprocating screw 509 and slidably connected to the slide rod 506, performs reciprocating linear motion under the action of both. The gear rod 508, which is fixed to the side wall of the slider 507, reciprocates accordingly. The transmission gear 504, which is meshed with the gear rod 508, is driven to rotate alternately in both directions. This causes the connecting shaft 502 to drive the air guide plate 503 to rotate alternately in both directions. Adjusting the angle of the air guide plate 503 changes the direction and range of the cooling air, so that the cooling air is evenly blown to all parts of the metering box body 1.
