Description

Technical Field

[0001] The utility model relates to the technical field of valve equipment parts, in particular to a rain shielding structure for valve electrical accessories. Background Art

[0002] An electrical accessory is provided on the valve equipment to control the operation of the valve. In order to prevent the electrical accessory of the valve from being eroded by environmental factors such as rain and moisture, a rain shield is generally installed on the valve to ensure the normal operation and service life of the electrical accessory.

[0003] At present, the rain shields for electrical accessories used in the industry generally adopt a bent integral structure board. The two bent parts of the rain shield are respectively used for installing the electrical accessory and shielding rain. Although this form of rain shield has a simple structure and is easy to manufacture, it has the following disadvantages: ① In order to reserve a maintenance space for the electrical accessory, a larger space is required to install and apply the valve with this rain shield; ② During the transportation, storage, and installation of the valve, the rain shield will occupy a large space and is prone to collision deformation; ③ During the installation and use of the valve, if the rain shield is deformed due to unexpected circumstances, the maintenance work is more difficult. It not only easily affects the electrical accessory installed on the rain shield, but also special tooling must be used for maintenance.

[0004] For example, the Chinese utility model patent document with the publication number CN219949785U discloses a dust conveying energy-saving valve. The technical solution thereof is that a rain shield is fixedly connected to the outer wall of one side of the shell. The rain shield is located above the motor. Through the combined use of the rain shield and the rust-proof coating, the rain shield can shield the motor from rain and prevent the motor from being easily short-circuited due to being wet by rain. Although the technical solution disclosed in this patent uses a separate rain shield to shield and protect the motor, the rain shield is directly fixedly connected to the shell of the valve, which is not convenient for disassembly, and thus not convenient for overhauling and maintaining the rain shield and the motor below the rain shield. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a rain shielding structure for valve electrical accessories that is convenient for replacing the rain shield and convenient for overhauling the electrical accessory.

[0006] The technical solution adopted by the present utility model to solve the above technical problems is: a rain shielding structure for valve electrical accessories. The rain shielding structure for valve electrical accessories is a split structure composed of an electrical accessory mounting plate and a rain shielding plate. An electrical accessory of the valve is mounted on one side of the electrical accessory mounting plate. The edge of the rain shielding plate is bent to form a connecting portion, and the connecting portion is detachably connected to the side of the electrical accessory mounting plate where no electrical accessory is mounted through bolts. The rain shielding plate forms a shield above the electrical accessory mounted on the electrical accessory mounting plate. A buckle groove is also provided on the electrical accessory mounting plate, and the connecting portion of the rain shielding plate is bent to form a bent edge that is buckled and matched with the buckle groove.

[0007] As an improvement to the above solution: a convex block is fixed on the side of the electrical accessory mounting plate where no electrical accessory is mounted, and the buckle groove is provided on the convex block. The convex block abuts against the connecting portion of the rain shielding plate to form a protection space between the connecting portion and the electrical accessory mounting plate, and the bolt passes through the protection space.

[0008] As an improvement to the above solution: the buckle groove on the convex block opens downward, and the bent edge is bent upward. When the bent edge is buckled and matched with the buckle groove, the bent edge wraps the convex block.

[0009] As an improvement to the above solution: the electrical accessory mounting plate and the rain shielding plate are hinged and connected through a hinge, and both ends of the hinge are detachably connected to the connecting portion of the rain shielding plate and the electrical accessory mounting plate respectively.

[0010] As an improvement to the above solution: it further includes a positioning groove provided on the side of the rain shielding plate facing the electrical accessory mounting plate, and the top end of the electrical accessory mounting plate is inserted into the positioning groove to form a limit fit.

[0011] The beneficial effects of the present utility model are as follows: by improving the integral rain shielding plate that is simultaneously used for mounting electrical accessories and shielding electrical accessories in the prior art into a split structure, the electrical accessory mounting plate is used solely for mounting the electrical accessories of the valve, the rain shielding plate is used solely for shielding the electrical accessories, and the electrical accessory mounting plate and the rain shielding plate are assembled by means of bolt connection and buckle fit. During the transportation and storage of the valve, the electrical accessory mounting plate and the rain shielding plate can be disassembled and separated, thereby reducing the occupied space of the entire rain shielding plate structure; when it is necessary to repair the rain shielding plate or electrical accessories, the rain shielding plate can be conveniently disassembled from the electrical accessory mounting plate, so as to quickly release the repair space of the rain shielding plate or electrical accessories and achieve the rapid replacement and repair of the entire rain shielding plate structure.

At the same time, the bent edge 220 is formed by bending the connecting portion 210 once, and the bent edge 220 is horizontally inserted into the snap groove 110 to form a snap fit. In the second embodiment, whether a protective space 400 is formed between the connecting portion 210 of the rain shield 200 and the electrical accessory mounting plate 100 can be determined according to the depth of the arranged snap groove 110; when there is a protective space 400, the bent edge 220 can form a shield below the protective space 400, playing a protective role for the middle threaded section of the bolt 300 passing through the protective space 400.

[0025] Furthermore, the present utility model improves the structure of the above embodiment. On the basis of adopting the bolt connection and snap fit structure, a hinge 500 is added between the electrical accessory mounting plate 100 and the rain shield 200. As Figure 3 and Figure 4 shown, both ends of the hinge 500 are detachably connected to the connecting portion 210 of the rain shield 200 and the electrical accessory mounting plate 100 respectively by screws, so that the electrical accessory mounting plate 100 and the rain shield 200 are hingedly connected through the hinge 500. When it is necessary to repair the electrical accessory, after detaching the bolt 300, the rain shield 200 can be flipped to expose the electrical accessory on the electrical accessory mounting plate 100, and sufficient space can be left to repair the electrical accessory without disassembling the entire rain shield structure for the valve electrical accessory. In addition, when adopting the structure of this embodiment, the snap groove 110 needs to leave enough width margin to avoid hindering the flipping action of the rain shield 200.
