Description

Technical Field

[0001] The present invention relates to the technical field of electrical automation equipment, and particularly to an electrical automation energy-saving device for water supply and drainage. Background Art

[0002] The background art of the electrical automation energy-saving device for water supply and drainage mainly stems from the current society's urgent need for energy conservation and emission reduction. With the implementation of the sustainable development strategy, the tense situation of water resource supply in China has become increasingly prominent. Many urban and rural areas are facing the problem of insufficient water supply. In order to relieve the pressure of water resource supply and improve the utilization efficiency of water resources, the application of energy conservation and emission reduction technologies in water supply and drainage projects has become particularly important. The electrical automation energy-saving device has emerged as the times require. It realizes the precise control of the water supply and drainage process and the efficient utilization of energy through advanced electrical automation technologies and control systems. The application of this device can not only reduce the operation cost and energy waste, but also improve the working efficiency and stability of the water supply and drainage system, which is of great significance for promoting the green development of the water supply and drainage industry.

[0003] In the actual use process of the existing device, impurities in the water pipe are filtered by setting a filter screen in the pipe to ensure the normal water absorption of the device and thus reduce power consumption. However, if the impurities filtered out by the filter screen are not processed for a long time, they are likely to accumulate, thus blocking the filter screen, which not only affects the filtering effect of the filter screen, but also causes the pipe to be blocked, and requires personnel to frequently replace the filter screen, which is inconvenient to use. Therefore, an electrical automation energy-saving device for water supply and drainage is proposed. Summary of the Invention

[0004] The purpose of the present invention is to solve the disadvantages in the prior art that impurities in the water pipe are filtered by setting a filter screen in the pipe to ensure the normal water absorption of the device and thus reduce power consumption. However, if the impurities filtered out by the filter screen are not processed for a long time, they are likely to accumulate, thus blocking the filter screen, which not only affects the filtering effect of the filter screen, but also causes the pipe to be blocked, and requires personnel to frequently replace the filter screen, which is inconvenient to use, and to propose an electrical automation energy-saving device for water supply and drainage.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] An electrical automation energy-saving device for water supply and drainage, including a water absorption pipe. A filter housing is fixedly connected to the upper part of the water absorption pipe. A filter plate is arranged inside the filter housing. A cleaning mechanism is fixedly connected to the upper part of the filter housing. The cleaning mechanism includes a cleaning housing fixedly connected to the upper part of the filter housing. A servo motor is arranged inside the cleaning housing. A worm is arranged at the output end of the servo motor. The worm is meshed with a worm wheel. The worm wheel is rotationally connected to the cleaning housing. A second gear is fixedly connected to the side of the worm wheel away from the cleaning housing. The second gear is meshed with a first rack. A moving plate is fixedly connected to the bottom of the first rack. A rubber scraper is fixedly connected to the front end of the moving plate. Threaded rods are connected to both sides of the moving plate. The threaded rods are rotationally connected to the filter housing. A first gear is fixedly connected to the bottom of the threaded rod. The first gear is meshed with a second rack. A movable connecting plate is fixedly connected to the side of the second rack away from the first gear. The movable connecting plate is slidably connected to the filter housing.

[0007] When absorbing water, impurities in the water are filtered by the filter plate. When drainage is not required, the servo motor is started. The servo motor drives the second gear to rotate. The rotation of the second gear drives the engaged first rack to move downward. The downward movement of the first rack drives the moving plate to move downward, thereby driving the rubber scraper to scrape the impurities attached to the surface of the filter plate. While the moving plate moves downward, it drives the first gear to rotate. The rotation of the first gear drives the movable connecting plate to move, thereby opening the bottom of the filter housing, so that the impurities scraped by the rubber scraper are discharged from the opening. A chute is arranged inside the water absorption pipe, and the chute is used for the filter plate to be slidably connected. A chute is arranged at the bottom of the filter housing, and the chute at the bottom of the filter housing is used for the movable connecting plate to be slidably connected. When the movable connecting plate completely closes the opening at the bottom of the filter housing, the liquid will not overflow.

[0008] The above technical solution further includes:

[0009] A limiting groove is fixedly connected inside the cleaning housing, and the first rack is slidably connected inside the limiting groove.

[0010] The filter plate is slidably connected to the filter housing, and a handle is fixedly connected to the upper part of the filter plate.

[0011] Two mounting pins are fixedly connected to the lower part of the filter plate. A clamping groove for clamping a limiting steel ball is arranged at the lower part of the mounting pin, and the mounting pin can be inserted into the mounting housing.

[0012] Two locking mechanisms are fixedly connected to the bottom of the filter housing. The locking mechanism includes a mounting housing fixedly connected to the bottom of the filter housing.

[0013] Four limiting steel balls are arranged at the upper part of the mounting housing, and the limiting steel balls are slidably connected to the mounting housing.

[0014] A piston is slidably connected inside the installation housing. An unlocking air passage is formed between the upper part of the piston and the installation housing. A locking air passage is formed between the lower part of the piston and the installation housing. One side of the unlocking air passage and the locking air passage is communicated with a ventilation port. A sealing cover is threadedly connected to one side of the ventilation port.

[0015] A spring is fixedly connected to the lower part of the piston, and the lower part of the spring is fixedly connected to the installation housing.

[0016] A drainer is fixedly connected to one side of the water absorption pipe away from the filter housing.

[0017] The present invention has the following beneficial effects:

[0018] 1. In the present invention, when the drainer is not working, the cleaning mechanism can drive the moving plate to move downward. During the movement of the moving plate, the rubber scraper fixedly connected to the front end can scrape downward along the surface of the filter plate. The rubber scraper can effectively scrape off the impurities accumulated on the surface of the filter plate, thereby avoiding the accumulation of impurities and affecting the filtering effect of the filter plate. Moreover, when the moving plate moves downward, it can also drive the threaded rod to rotate. By the rotation of the threaded rod, the movable connecting plate can be driven to move, thereby opening the bottom of the filter housing. The impurities scraped off by the rubber scraper can just be discharged from the opening, effectively avoiding the accumulation of impurities and reducing the frequency of replacing the filter plate.

[0019] 2. In the present invention, a handle is provided on the upper part of the filter plate, which is convenient for taking and placing the filter plate. During use, the user can insert the filter plate into the filter housing from the upper part. When the filter plate is inserted to the bottom of the filter housing, the installation pin provided at the lower part of the filter plate can enter the installation housing. The user only needs to introduce gas into the ventilation port on the side of the locking air passage. The increase in air pressure in the locking air passage and the combined action of the spring can drive the piston to move upward, thereby driving the limit steel balls to move inward and locking the installation pin, so that the installation of the filter plate can be quickly realized, which not only ensures the installation efficiency of the filter plate, but also improves the connection stability.

A second gear (25) is fixedly connected to the side of the worm gear (24) away from the cleaning housing (4). The second gear (25) is meshed with a first rack (8). A moving plate (9) is fixedly connected to the bottom of the first rack (8). A rubber scraper (21) is fixedly connected to the front end of the moving plate (9).

A movable connecting plate (7) is fixedly connected to the side of the second rack (12) away from the first gear (11). The movable connecting plate (7) is slidably connected to the filter housing (3).

[0031] When sucking water, impurities in the water are filtered by the filter plate (5). When drainage is not required, the servo motor (22) is started. The second gear (25) is driven to rotate by the servo motor (22). The rotation of the second gear (25) drives the engaged first rack (8) to move downward. The downward movement of the first rack (8) drives the moving plate (9) to move downward, thereby driving the rubber scraper (21) to scrape the impurities attached to the surface of the filter plate (5). While the moving plate (9) moves downward, the first gear (11) is driven to rotate. The rotation of the first gear (11) drives the movable connecting plate (7) to move, thereby opening the bottom of the filter housing (3), so that the impurities scraped by the rubber scraper (21) are discharged from the opening. A chute is arranged inside the water suction pipe (1), and the chute is slidably connected to the filter plate (5). A chute is arranged at the bottom of the filter housing (3), and the chute at the bottom of the filter housing (3) is slidably connected to the movable connecting plate (7).

[0032] In this embodiment, when the drainer (2) is working, the water suction pipe (1) sucks water, and the water flows into the drainer (2) through the water suction pipe (1). When the water flows through the filter housing (3), the filter plate (5) arranged inside the filter housing (3) can filter the impurities in the water. When the drainer (2) is not working, the servo motor (22) can drive the worm (23) to rotate. The rotation of the worm (23) drives the meshing-connected worm wheel (24) to rotate, and the rotation of the worm wheel (24) can drive the fixedly-connected second gear (25) to rotate. The rotation of the second gear (25) drives the meshing-connected first rack (8) to move. The limiting groove (26) slidably connected during the movement of the first rack (8) can ensure the stability of the first rack (8) during movement. The movement of the first rack (8) drives the fixedly-connected moving plate (9) to move downward. The rubber scraper head (21) arranged at the front end during the movement of the moving plate (9) can scrape downward along the surface of the filter plate (5), thereby cleaning the impurities accumulated on the surface of the filter plate (5) and preventing the accumulation of impurities from affecting the filtering effect of the filter plate (5).

[0033] While the moving plate (9) moves downward, it can also drive the screw-threaded connection of the threaded rod (10) to rotate. The rotation of the threaded rod (10) can drive the first gear (11) to rotate. The rotation of the first gear (11) drives the meshing-connected second rack (12) to move.

The impurities scraped off by the rubber scraper head (21) can just be discharged from the opening, effectively avoiding the accumulation of impurities and reducing the frequency of replacing the filter plate (5).

A handle (27) is fixedly connected to the upper part of the filter plate (5), and two mounting pins (13) are fixedly connected to the lower part of the filter plate (5). A clamping groove for the limiting steel ball (20) to be clamped is opened at the lower part of the mounting pin (13). The mounting pin (13) can be inserted into the mounting housing (6). Two locking mechanisms are fixedly connected to the bottom of the filter housing (3). The locking mechanism includes a mounting housing (6) fixedly connected to the bottom of the filter housing (3).

[0036] Four limiting steel balls (20) are arranged on the upper part of the installation housing (6). The limiting steel balls (20) are slidably connected to the installation housing (6). A piston (14) is slidably connected inside the installation housing (6). An unlocking air passage (16) is formed between the upper part of the piston (14) and the installation housing (6). A locking air passage (17) is formed between the lower part of the piston (14) and the installation housing (6).

When the filter plate (5) needs to be replaced, only by introducing air into the unlocking air passage (16) through the ventilation port (18) on one side of the unlocking air passage (16), the air pressure can drive the piston (14) to move downward, so that the limiting of the limiting steel balls (20) is released, and the installation pin (13) can be inserted and pulled out at will, and the connection is convenient and easy to replace.
