Description

Technical Field

[0001] This utility model belongs to the field of water tank technology, and specifically relates to a drainage mechanism for a water tank. Background Technology

[0002] Water tanks are widely used water storage or heat dissipation devices in various fields. They can be classified into automotive water tanks, bathroom water tanks (such as toilet tanks), and industrial / water treatment water tanks according to their usage scenarios. Their core functions include water storage, heat dissipation, temperature control, or water treatment. In order to facilitate the normal drainage of water tanks, drainage mechanisms are required. Existing drainage mechanisms typically use valves to discharge water from the tank. These valves are installed on the surface of the drain pipe to control the water flow. However, in actual use, the following problems exist: when the valve is used for a long time, scale or other impurities in the water flow can easily clog it, which can prevent the valve from draining properly. To address these issues, we propose a new drainage mechanism for the water tank. Utility Model Content

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a drainage mechanism for a water tank, comprising a water tank body, a drain pipe bolted to the surface of the water tank body, a valve bolted to the surface of the drain pipe, a housing bolted to both sides of the drain pipe, a telescopic rod bolted to the bottom of one side of the inner cavity of the housing, a spring sleeved on the surface of the telescopic rod, a reset plate bolted to one side of the spring, a sliding sleeve bolted to the top of the reset plate, a sliding plate bolted to the top of the sliding sleeve, a pull rod bolted to one side of the sliding plate, an insert block bolted to the other side of the sliding plate, an installation plate inserted into one side of the insert block, a filter screen plate welded to one side of the installation plate, and the bottom of the filter screen plate penetrating into the inner cavity of the drain pipe and fitting against the bottom of the inner cavity of the drain pipe.

[0005] The above technical solution facilitates the filtration of discharged water through the filter screen, effectively removing scale and other impurities from the water flow. This prevents scale and other impurities from entering the valve cavity and causing blockage, thus improving the valve's efficiency. The extension rod, spring, reset plate, sliding sleeve, and sliding plate facilitate the limiting or releasing of the mounting plate, making it easy to disassemble and install the mounting plate. This also allows for easy disassembly, cleaning, and maintenance of the filter screen, further enhancing its efficiency.

[0006] The present invention is further configured such that a screw block is welded to the surface of the shell, and a locking bolt is threaded into the inner cavity of the screw block.

[0007] The above technical solution facilitates the insertion of the locking block using screw blocks and locking bolts, making it easy to lock the sliding sleeve. This avoids the influence of the elasticity of the spring and telescopic rod, preventing the insertion block from contracting during static periods and improving the stability of the filter screen installation.

[0008] The present invention is further configured such that a locking block is welded to the surface of the sliding sleeve, and a screw hole is provided on the surface of the locking block, and the inner cavity of the screw hole is threadedly connected to the surface of the locking bolt.

[0009] The above technical solution allows for easy insertion of locking bolts through screw holes.

[0010] The present invention is further configured such that a groove is formed on the surface of the mounting plate, and one side of the insert block is inserted into the inner cavity of the groove.

[0011] The above technical solution facilitates the insertion of the plug by using grooves.

[0012] The present invention is further configured such that a sliding rod is fitted inside the sliding sleeve, and both sides of the sliding rod are welded to the inner wall of the housing.

[0013] The above technical solution improves the stability of the sliding sleeve by using a sliding rod.

[0014] The present invention is further configured such that a limiting groove is provided at the bottom of the inner cavity of the housing, and the bottom of the reset plate is slidably connected to the inner cavity of the limiting groove.

[0015] The above technical solution improves the stability of the reset plate's sliding by using the limiting groove.

[0016] The present invention is further configured such that an opening is provided at the top of the inner cavity of the drain pipe, and a sealing ring is bonded to the inner cavity of the opening, and the inner cavity of the sealing ring is attached to the surface of the filter screen.

[0017] The above technical solution utilizes a sealing ring to facilitate sealing at the connection between the filter screen and the inlet.

[0018] In summary, this utility model has the following beneficial effects: 1. The filter screen facilitates the filtration of discharged water, effectively removing scale and other impurities from the water flow. This prevents scale and other impurities from entering the valve cavity and causing blockage, thus improving the valve's efficiency. The extension rod, spring, reset plate, sliding sleeve, and sliding plate facilitate the limiting or releasing of the mounting plate, making it easy to disassemble and install the mounting plate. It also makes it easy to disassemble, clean, and maintain the filter screen, further improving its efficiency. 2. The screw block and locking bolt facilitate the insertion of the locking block and the locking of the sliding sleeve. This avoids the impact of the elasticity of the spring and telescopic rod, which causes the insertion block to contract during the stationary process, thus improving the stability of the filter screen installation. The screw hole facilitates the insertion of the locking bolt, the groove facilitates the insertion of the insertion block, and the limit groove improves the stability of the reset plate sliding.
