[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1

[0025] In the prior art, after long-term use, there is a problem that the valve gear box and the connected box cover are easily separated. This embodiment provides a valve gear box with strong waterproof sealing performance, which can firmly fix the box cover and the gear box together, extending the service life of the entire device. Please refer to Figure 1-Figure 5 This highly waterproof and airtight valve gearbox includes a cover 2 connected to the top of a housing 1 via a fixing bolt. The fixing bolt serves as a preliminary fixation for the cover 2. A reinforcement mechanism 3 is located on the top of the cover 2, facilitating access to the internal structure of the housing 1. These reinforcement mechanisms 3 are symmetrically arranged on the sides of the cover 2, enhancing the secure installation of the cover 2. A transmission mechanism 4 is located within the housing 1, providing stable operation. The reinforcement mechanism 3 further reinforces the cover 2 and facilitates quick removal of the entire cover 2 for access to the internal structure of the housing 1. The transmission mechanism 4 provides more stable valve operation and also provides a certain degree of waterproofing.

[0026] In the process of installing the box cover 2, in order to be able to quickly and firmly fix the box cover 2 on the box body 1, the reinforcement mechanism 3 includes a fixed block 31 fixedly installed on the side of the box body 1, and the fixed block 31 is rotatably connected to the rotating block 32. By rotating the rotating block 32, the connecting frame 33 can be driven to rotate so that the bottom end of the connecting frame 33 contacts the top end of the box cover 2. The connecting frame 33 is fixedly installed on the top of the rotating block 32, and the pressure plate 34 is fixedly installed on the top of the connecting frame 33. The top of the box cover 2 is fixedly installed with a fixing column 35, and the outer surface of the fixing column 35 The wall is rotatably connected to a card plate 36, and the card plate 36 is connected to the connecting frame 33 by rotating to the inside of the card slot on one side of the connecting frame 33, so that the connecting frame 33 can be fixed, thereby facilitating the disassembly and assembly of the box cover 2. A limit ring 37 is fixedly installed on the outer wall of the fixing column 35, and the limit rings 37 are symmetrically distributed on the upper and lower sides of the card plate 36, so as to support the card plate 36. A baffle 38 is movably installed on the top of the box cover 2, and the baffle 38 plays the role of limiting support. The fixed end of the baffle 38 is threadedly connected to a connecting bolt 39.

[0027] Remove the fixing bolt at the top of the box cover 2, rotate the card plate 36 under the support of the limit ring 37 to separate it from the card slot on one side of the connecting frame 33, and then press the pressure plate 34 to make the connecting frame 33 rotate under the rotation of the rotating block 32, so that its bottom end is separated from the top of the box cover 2, so that the box cover 2 can be quickly removed, and the structure inside the box body 1 can be quickly and conveniently inspected and maintained.

[0028] Example 2

[0029] Based on Example 1, Figure 1-Figure 4 As shown, based on the problem that the existing valve gear box and the connected box cover 2 are prone to separation, when the valve is driven, the water at the connection with the valve can easily penetrate into the box body 1 after long-term use, thereby easily affecting the driving operation of the internal structure of the box body 1. The device is also provided with a structure that has stable driving and improved waterproof sealing.

[0030] In the process of driving the valve, in order to stably drive the valve and improve the rotation stability of the valve, the transmission mechanism 4 includes a driving motor 41 installed inside the box body 1, and the output end of the driving motor 41 is connected to the transmission rod 42. A support member 43 is provided inside the box body 1. The support member 43 is fixed to the inside of the box body 1 through two groups of connecting nails 44, so that it can be quickly disassembled and assembled, and the support members 43 are symmetrically distributed on both sides of the rotating shaft 45. The support members 43 play a supporting role on the rotating shaft 45, so that it can rotate more stably. The fixed end of the support member 43 A connecting nail 44 is threadedly connected, and a rotating shaft 45 is rotatably connected inside the support 43. A worm gear 46 meshing with the transmission rod 42 is fixedly installed on the outer wall of the rotating shaft 45, and a transmission sleeve 47 is fixedly installed on the outer wall of the rotating shaft 45. A bearing 48 is installed at the bottom end of the box body 1. The bearing 48 plays a load-bearing role. An installation shaft 49 is installed inside the bearing 48 for connecting the relevant structure of the valve. A worm gear 2 410 meshing with the transmission sleeve 47 is fixedly installed above the outer wall of the installation shaft 49. A waterproof sealing component 401 that can isolate the water at the valve connection is provided inside the box body 1. The drive motor 41 drives the transmission rod 42 to rotate. Since the transmission rod 42 is engaged with the worm gear 1 46, the rotating shaft 45 rotates stably under the support of the support member 43 and the connection of the worm gear 1 46. Since the worm gear 2 410 is engaged with the transmission sleeve 47, the rotation of the transmission sleeve 47 drives the installation shaft 49 installed inside the worm gear 2 410 to rotate, and then drives the relevant structures of the valve connected to the bottom end of the installation shaft 49 to rotate under the support connection of the bearing 48, thereby improving the stability of the valve operation.

[0031] When the valve is driven, the connection between the valve and the device can be waterproofed and sealed. In order to improve the waterproof and sealing performance of the device, the waterproof sealing assembly 401 includes an upper sealing ring 411 installed at the corresponding position of the bearing 48 inside the box body 1, which can seal the interior of the box body 1. A sealing gasket 412 is installed at the bottom end of the box body 1, which can further waterproof and seal the bottom end of the outside of the box body 1, thereby improving the waterproof and sealing performance of the entire device. A waterproof cover 413 is slidably connected to the top of the box cover 2. The waterproof cover 413 covers the drive motor 41 inside it, and a soft packing plate is fixedly installed on one side of the interior of the waterproof cover 413. The waterproof cover 413 and the soft packing plate both play a role in protecting the drive motor 41, which can extend the service life of the drive motor 41. The upper sealing ring 411 and the sealing gasket 412 play a double waterproof and sealing role, improving the waterproof and sealing performance of the entire device. The waterproof cover 413 can protect the drive motor 41.
