TECHNICAL FIELD

[0001] The present application relates to the field of valve protection, in particular to a valve gear box waterproof protection device and a method thereof. BACKGROUND

[0002] The valve gear box is a mechanical device for controlling the opening and closing of the valve, which realizes the precise operation of the valve through the gear transmission system. However, the sealing elements (such as sealing rings and sealing pads) of the valve gear box will lose their sealing performance due to aging and wear after long-term use, thereby causing gaps between the sealing elements and the valve gear box. In the open air environment, if the protection measures are insufficient, rainwater will enter the inside of the gear box through the gaps, which will cause the water to enter the inside of the gear box, thus causing the internal parts of the valve gear box to rust and corrode, affecting the normal use of the valve gear box.

[0003] For example, the utility model patent (application number: 201920857560.7) discloses a "valve gear box protection cover", the specification discloses that during the maintenance and repair of the valve gear box, a small amount of water is found in the open-air valve gear box after the upper cover is opened, which causes serious rust and corrosion of the worm and gear, and the sealing material of the gear box is aged and fails. The above patent can prove the defects existing in the prior art.

[0004] Therefore, we improve it and propose a valve gear box waterproof protection device and a method thereof. SUMMARY

[0005] The purpose of the present application is to solve the problem that the valve gear box protection device in the prior art is used in the open air, rainwater contacts the internal parts of the valve gear box and causes them to rust and corrode, affecting the normal use of the valve gear box.

[0006] In order to achieve the above-mentioned purpose of the application, the valve gear box waterproof protection device and the method thereof are provided to improve the above-mentioned problems.

[0007] The present application is as follows: It comprises a mounting frame, a mounting hole arranged on the mounting frame, and a waterproof mechanism arranged on the mounting frame. The waterproof mechanism comprises a U-shaped frame rotatably arranged on the mounting frame, a filter screen arranged on the U-shaped frame, a pull ring arranged on the U-shaped frame, and a water outlet hole arranged on the pull ring.

[0008] As a preferred technical solution of the present application, the water outlet hole and the filter screen are adapted to each other, and the end of the pull ring close to the filter screen is wedge-shaped.

[0014] As a preferred technical scheme of the present application, the mounting frame is provided with a drainage block, the end of the drainage block is wedge-shaped, and the drainage block is matched with the filter screen.

[0015] As a preferred technical scheme of the present application, the mounting frame is provided with a sealing ring.

[0016] The valve gear box waterproof protection method is as follows: Compared with the prior art, the present application has the following beneficial effects: In use, the mounting frame is installed on the wall body, so that the existing valve gear box is located in the mounting frame, the installation hole is used for fixing the pipeline connected with the valve, when it rains, the rainwater contacts the filter screen, the filter screen has water absorption, the rainwater is absorbed through the filter screen, so that the rainwater is gathered on the surface of the filter screen, at this time, the rainwater on the surface of the filter screen slides downward under the action of gravity, at the same time, when the filter screen contacts the rainwater, the rainwater blocks the holes of the filter screen, thereby reducing the contact between the external humid air and the valve gear box, at this time, the rainwater is discharged along the water outlet hole. When the weather is fine, the filter screen can be used for filtering the dust and impurities in the external air, and the existing valve gear box is in full contact with the external air through the filter screen, so that the ventilation is improved, and the existing valve gear box is kept dry, when the external air is humid, the filter screen can absorb the humid air, so that the humid air cannot contact the filter screen. Step S3, by rotating the knob, the knob drives the driving shaft and the transmission roller to rotate synchronously, the transmission roller drives the filter screen to rotate synchronously, the filter screen rotates and contacts the pull ring, one end of the pull ring close to the filter screen is wedge-shaped and abuts against the filter screen, and the impurities on the surface of the filter screen are scraped off through the wedge-shaped end of the pull ring. In step S4, when the rectangular block is slidably installed in front of the rectangular groove, the torsion spring is stored by rotating the rectangular block. At this time, the rectangular block is installed in the rectangular groove. At this time, the torsion spring drives the fixed shaft and the U-shaped frame to rotate synchronously, and makes the U-shaped frame close to the installation frame. In this way, when maintaining or inspecting the existing valve gearbox, it is only necessary to pull the pull ring to rotate the U-shaped frame open. When the device is not in use, the elasticity of the torsion spring makes the U-shaped frame close to the installation frame.

To address the problem in the prior art that when valve gear box protection devices are used outdoors, rainwater may come into contact with the internal parts of the valve gear box, causing them to rust and corrode, thus affecting the normal use of the valve gear box, the present application provides a waterproof mechanism. On rainy days, the waterproof mechanism drives the filter to absorb and drain rainwater and moist air, preventing rainwater from directly contacting the valve gear box, thereby extending the service life of the existing valve gear box. 2. The waterproof mechanism is set up to filter dust and impurities from the outside air through the filter when the weather is clear, and the existing valve gear box is fully exposed to the outside air, thereby improving ventilation, keeping the existing valve gear box dry, and reducing the rust and corrosion of the internal parts of the existing valve gear box. This solves the problem of condensed water corroding the internal parts of the valve gear box in the existing technology; 3. Through the provision of a waterproof mechanism, the filter screen and the U-shaped frame can be quickly installed and disassembled through sliding installation. When the existing valve gear box needs to be maintained or inspected, the quick disassembly of the protective device can save time and improve the convenience of maintenance work, thus solving the problem of low practicality caused by the troublesome disassembly of the existing protective device in the prior art.
