Description
Technical Field
[0001] This utility model relates to the field of protection technology for outdoor valve gearboxes, specifically to a rainproof device for outdoor valve gearboxes. Background Technology
[0002] Outdoor valves are widely used in water conservancy projects, chemical facilities, urban water supply and drainage systems, and energy transmission pipelines. Their gearboxes, as key components controlling valve operation, are typically exposed to the open environment. Especially in long-distance pipelines and gathering / transmission stations, outdoor valve gearboxes are constantly exposed to the natural environment, making them susceptible to corrosion and damage from rainwater, affecting normal valve operation and even causing safety accidents. Furthermore, the valve position indicator on the gearbox requires clear observation by operators to understand the valve's operating status.
[0003] Due to long-term exposure to rain, dust, ultraviolet radiation, and other natural elements, the internal mechanical structure of gearboxes is prone to rust, jamming, or short circuits in electrical components, leading to valve malfunctions and even safety accidents. Therefore, effective rain protection for outdoor valve gearboxes is crucial. However, existing rain protection measures often employ simple waterproof covers or sealing caps, which have significant structural defects: for example, waterproof covers are mostly fixed designs, unable to accommodate the irregular shapes (such as curved or inclined surfaces) of the upper surfaces of different gearbox models, resulting in inadequate sealing after installation and allowing rainwater to easily seep in through gaps; at the same time, traditional devices are usually fixed using bolts or welding, making installation cumbersome, requiring specialized tools, and difficult to disassemble during maintenance or inspection, increasing operation and maintenance costs and time consumption.
[0004] Existing rainproof devices also have functional limitations. Most rain covers are made of opaque materials, hindering workers from directly observing the valve position indicator on the top of the gearbox. This necessitates frequent disassembly of the cover for valve status monitoring, reducing work efficiency and potentially introducing secondary damage during disassembly. Furthermore, conventional connection methods (such as welding or gluing) lack adjustability. When the gearbox surface becomes uneven due to manufacturing tolerances or wear, the rain cover cannot fit tightly, resulting in waterproofing failure. The magnetic pad and screw adjustment design mentioned in Example 1 of the manual addresses this problem, but existing technologies generally lack such flexible adjustment mechanisms, leading to a narrow range of applications for rainproof devices and making it difficult to meet diverse field needs. Utility Model Content
[0005] The main purpose of this invention is to provide a device that can prevent outdoor valve gearboxes from getting wet from rain.
[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows: An outdoor valve gearbox rainproof device includes a rain cover with multiple through holes on the top plate. The upper end of a connector is detachably fixed in the through holes, and the lower end of the connector is threadedly connected to a screw rod with a magnetic washer fixed to the lower end of the screw rod. The connector includes a support column with a threaded hole at the upper end. The threaded rod of a screw passes through the through hole and is threadedly connected to the threaded hole at the upper end of the support column. The nut of the screw and the upper end of the support column press against the top plate of the rain cover.
[0007] Specifically, the rain cover is made of a transparent material.
[0008] Specifically, the lower end of the screw nut is fixedly sealed with a sealing ring, and the screw nut is sealed to the top plate of the rain cover through the sealing ring.
[0009] Specifically, a valve stem groove is provided at the lower end of the vertical sidewall on one side of the rain cover, and the valve stem of the outdoor valve passes through the valve stem groove.
[0010] Specifically, the rain cover is rectangular in shape, with an opening at the bottom and the upper part of the outdoor valve gearbox located inside the rain cover.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This device has a reasonable structural design and is applicable to a wide range of scenarios. It does not require complex professional tools or cumbersome construction steps, and the installation and operation process is simple. It can achieve reliable rain protection for outdoor valve gearboxes and clear observation of valve positions. It can be widely promoted and applied to valve operation and maintenance fields such as long-distance pipelines and gas extraction and transportation stations. It is of great significance for improving valve operation stability and reducing operation and maintenance costs, and has broad application prospects.
[0012] 2. Through the threaded connection design of the magnetic pads and screws, the height of each magnetic pad can be independently rotated and adjusted, so that the rain cover can fit tightly against the irregular plane on the top of the outdoor valve gearbox, such as curved, inclined or concave surfaces, eliminating installation gaps caused by uneven surfaces, preventing rainwater from seeping in, and significantly enhancing the rain cover's sealing performance and environmental adaptability.
[0013] 3. The connector adopts a split design. Simply pass the screw through the hole in the rain cover and screw it into the threaded hole of the support column. With the magnetic pad for adsorption and fixation, the installation can be completed without welding or complicated tools, which improves the efficiency of installation or disassembly. During maintenance, the rain cover can be quickly removed to reduce operation and maintenance costs.
[0014] 4. A sealing ring is added to the lower end of the screw and nut to form a secondary seal with the top plate of the rain cover; the valve stem groove design allows the valve stem to pass through the side wall, avoiding cutting the rain cover body; the sealing ring prevents rainwater from entering through the perforation, and the valve stem groove is compatible with different valve stem sizes, expanding the applicability of the device.
[0015] 5. The rain cover is made of transparent material, allowing staff to directly observe the valve position indicator on the top of the outdoor valve gearbox through the cover; the valve status can be monitored in real time without removing the rain cover, reducing the risk of misoperation and ensuring the safe operation of the equipment.
[0016] 6. The magnetic pads are attached to the top of the gearbox, while the top plate of the rain cover is pressed by screws and the support column, forming a double fixation of magnetic force and mechanical pressure. This can resist the impact of external forces such as strong winds and vibrations, prevent the rain cover from shifting or falling off, and ensure long-term stable protection.
[0017] 7. The adjustable magnetic pads, screws, and supports can be combined without requiring customized modifications; the rectangular rain cover covers various outdoor valve gearbox shapes. One unit can accommodate multiple valve models, reducing spare parts inventory and lowering procurement and warehousing costs. Attached Figure Description

[0026] Specifically, the rain cover 2 is rectangular in shape, with an opening at the bottom, and the upper end of the outdoor valve gearbox 1 is located inside the rain cover 2.
[0027] The connector 3 includes a support column 302, which has a threaded hole at its upper end. The threaded rod of the screw 301 passes through the through hole 5 and is threadedly connected to the threaded hole at the upper end of the support column 302. The nut of the screw 301 and the upper end of the support column 302 press against the top plate of the rain cover 2.
[0028] The lower end of the nut of screw 301 is fixedly sealed with a sealing ring, and the nut of screw 301 is sealed to the top plate of rain cover 2 through the sealing ring.
[0029] A valve stem groove 4 is provided at the lower end of the vertical side wall on one side of the rain cover 2, and the valve stem of the outdoor valve passes through the valve stem groove 4.
[0030] During installation, thread the screw 301 through the through hole 5 and thread it into the threaded hole at the upper end of the support column 302.
