Description

Technical Field

[0001] This utility model relates to the field of drainage control technology, and in particular to an automatic drainage collection tank. Background Technology

[0002] Currently, automatic liquid level control technology is widely used in sewage treatment, industrial wastewater pumping, and other fields. Traditional liquid level control systems mostly use floats and laser rangefinders as sensing elements. By measuring the rise and fall of the float, they determine whether the float is at the design water level and control the start and stop of the water pump. However, sewage often contains impurities such as fibers, hair, and sludge, which easily become entangled at hinge points or on the surface of the float, causing the float to jam and the water level sensor to fail. In addition, the water level control accuracy of traditional float systems is low, and errors are common, leading to frequent pump start and stop, increasing energy consumption and maintenance costs. Existing technologies include improved solutions using isolation mesh covers. This solution involves adding a mesh cover around the float to prevent large particles of impurities from entering and adhering to the surface of the float and connecting rod, causing jamming. However, the mesh cover cannot solve the problem of fine fibers and sludge adhesion, and the mesh cover itself is prone to clogging.

[0003] Regarding the aforementioned technologies, although the mesh cover is inexpensive, its effect is minimal. The mesh cover itself is prone to clogging and cannot isolate and filter fine fibers and sludge. Therefore, the inventor believes that the current float-based sewage control system has the defect of the float being prone to jamming. Summary of the Invention

[0004] To address the problem of floats easily getting stuck, this application provides an automatically draining water collection tank.

[0005] This application provides an automatic drainage water collection tank, including a tank body, a tank cover, a float, a water pump, and a drain pipe; it also includes:

[0006] A sliding rod is vertically fixed inside the pool cover;

[0007] A slider is fitted onto the sliding rod, and the slider is connected and fixed to the float.

[0008] A scraper is provided on the top of the slider and is attached to the outer wall of the slider rod;

[0009] A scraper is disposed on the top of the slider and the blade is attached to the outer wall of the slider rod.

[0010] By adopting the above technical solution, the water collection tank uses a sliding rod and slider to restrict the float to slide up and down in a fixed vertical direction, transforming the float from a free-floating type to a unidirectional floating type. This reduces the likelihood of the float becoming entangled by impurities in the sewage within the tank, thus lowering the float failure rate. By installing a brush and a scraper on the slider, one above the other, as the slider moves along the sliding rod, the brush cleans the impurities attached to the rod, while the scraper simultaneously removes any remaining impurities, achieving thorough cleaning of the sliding rod and reducing the risk of the slider getting stuck.

[0011] Optionally, the scraper includes a roller with bristles and a mounting shaft for positioning the roller, with both ends of the mounting shaft fixed to the top of the slider, and the bristles adhering to the outer wall of the slider.

[0012] By adopting the above technical solution, the scraper is designed with a roller, which makes the scraper roll more smoothly as it slides on the slide bar with the slider, and reduces the impact on the slider resistance. Furthermore, by installing it on the top of the slider, it can be quickly installed and removed when maintenance is required.

[0013] Optionally, the inner wall of the slider is provided with a ball groove, and a ball that fits against the outer wall of the slider is installed in the ball groove.

[0014] By adopting the above technical solution, installing ball bearings on the inner wall of the slider can reduce the contact area between the slider and the slide rod, thereby reducing the frictional resistance between the slider and the slide rod, so that the slider can respond to the changes in the movement of the float in a timely manner and make a vertical displacement.

[0015] Optionally, the slide bar is provided with limiting rings for positioning the slider at a point above the water level line for starting the water pump and at a point below the water level line for turning off the water pump.

[0016] By adopting the above technical solution, the limiting ring can restrict the slider to slide within the range between the water level line when the water pump is closed and the water level line when the water pump is started, thus preventing the float ball from driving the slider to slide out of the sliding rod and escape the constraint of the sliding rod when there is too little or too much water in the collection tank.

[0017] Optionally, the pool cover has an insertion hole for inserting the slide rod into the pool body, a protective cover is installed on the top of the slide rod, a handle is installed on the protective cover, and a positioning hole is provided on the protective cover; the protective cover is connected and fixed to the pool cover through the positioning hole.

[0018] By adopting the above technical solution, the pool cover can seal and protect the water collection pool. The protective cover on top of the sliding rod can be quickly installed and removed from the sliding rod by bolt connection. The sliding rod connected to the protective cover can be pulled out of the water collection pool using the handle, facilitating cleaning and maintenance of the sliding rod. Furthermore, the connection and fixation between the protective cover and the pool cover can seal the water collection pool, providing safety protection and preventing debris from falling into the water collection pool.

[0019] Optionally, a rangefinder is installed on the side of the protective cover facing the inside of the pool.

[0020] By adopting the above technical solution, the rangefinder is installed on the side of the protective cover facing the inside of the pool and directly above the float. It can measure the distance between the float and the protective cover in a timely manner and transmit the signal to the controller that controls the start and stop of the water pump, so as to realize the automatic control of sewage pumping in the collection pool and reduce labor costs.

[0021] Optionally, the float is provided with a pin at its bottom, and the slider is provided with a fixing seat at its bottom. The fixing seat has a connecting hole for the pin to be inserted, and the float and the slider are fixedly connected by the pin thread.

[0022] By adopting the above technical solution, the float and slider are connected by a pin thread, which enables quick installation and disassembly, facilitating future use and maintenance.

[0023] Optionally, a filter column is provided on the outside of the slide rod, the filter column has filter holes, and a handle is provided on the top of the filter column.

[0024] By adopting the above technical solution, the filter column performs preliminary filtration of sewage in the collection tank, reducing impurities entering the sliding rod and float area, thereby reducing impurities adsorbed on the sliding rod and float. This avoids the decrease in sensitivity caused by the increase in volume and mass of the sliding rod and float due to the accumulation of impurities, and extends the service life and maintenance cycle of the float, slider and sliding rod.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The design of the scraper and scraper effectively prevents the float and connecting rod from being entangled by fibers, hair and other debris, thus improving the reliability of the sewage system.

[0027] 2. By setting up the slide bar and slider, the float can be made to move only vertically, which reduces the failure rate of float jamming, extends the service life of the float and control switch, and reduces the maintenance frequency. Attached Figure Description

[0035] The present application will be further described in detail below with reference to the accompanying drawings.

[0036] This application discloses an automatically pumping water collection tank. (Refer to...) Figure 1 , Figure 2 As shown, an automatic drainage collection tank includes a tank body 1, a tank cover 2, a water pump 3, a drain pipe 4, a sliding rod 5, a slider 6, a float 7, and a protective cover 8. The tank body 1 is used to collect and hold sewage. A water pump 3 is installed inside the tank body 1 and connected to the drain pipe 4. A filter column 9 is fixedly installed at the bottom of the tank body 1. The filter column 9 has filter holes 10 on its shaft, and a handle 11 is installed at the top. A sliding rod 5 is installed inside the filter column 9. The sliding rod 5 is preferably made of stainless steel and has a square cross-section. A protective cover 8 is installed at the top of the sliding rod 5. A slider 6 is sleeved on the sliding rod 5, and a float 7, which moves up and down by buoyancy, is connected to the slider 6.

[0037] Reference Figure 2 , Figure 3As shown, the sliding rod 5 is installed inside the pool body 1. The sliding rod 5 is preferably made of stainless steel and has a square cross-section. Limiting rings 12 are installed at the upper and lower ends of the sliding rod 5, respectively, at the water level line above the start-up water pump 3 and below the water level line below the stop-down water pump 3. The limiting rings 12 are preferably made of flexible material and can be disassembled. A protective cover 8 is installed on the top of the sliding rod 5. The protective cover 8 is connected to the sliding rod 5 by bolts 13. A rangefinder 14 is installed on the top of the protective cover 8 on the side facing the water collection pool and directly opposite the float 7. The rangefinder 14 is connected to the water pump 3 controller. The rangefinder 14 and the water pump 3 controller and their working principles are existing technologies, so this utility model will not elaborate further. A handle 15 is installed on the other side of the top of the protective cover 8. The handle 15 is preferably integrated with the protective cover 8. The protective cover 8 has a positioning hole 16 for covering and fixing to the pool cover 2, thereby realizing that the sliding rod 5 is fixed to the pool cover 2 through the protective cover 8.

[0038] Reference Figures 4 to 6 As shown, slider 6 is sleeved on slide rod 5. A ball groove 17 is formed on the inner wall of slider 6, and a ball 18 is installed in the ball groove 17. The ball 18 is tightly attached to the outer wall of slide rod 5. Preferably, the ball 18 protrudes 3mm from the inner wall of slider 6, creating a certain gap between slider 6 and slide rod 5 to prevent excessive friction from hindering the sliding of slider 6 on slide rod 5. A scraper 19 is integrally formed on the outermost part of the top of slider 6, and the scraper 19 is inclined and abuts against slide rod 5. A scraper 20 is mounted on the top of the slider 6. The main body of the scraper 20 is a roller 22 with bristles 21. The height of the roller 22 is higher than the blade height of the scraper 19. Preferably, the outermost edge of the bristles 21 on the roller 22 is about 1mm away from the outer wall surface of the slide rod 5 to avoid excessive friction from the roller 22 affecting the sensitivity of the slider 6 on the slide rod 5. Mounting shafts 23, which are fixed to the top of the slider 6, are connected to both sides of the roller 22. The mounting shafts 23 are integrally connected to the slider 6. A fixing seat 24 is provided at the bottom of the slider 6. The fixing seat 24 has a connection hole for connecting the float 7. The float 7 is threadedly connected to the fixing seat 24 by a pin 25.

[0039] The implementation principle of an automatic drainage collection tank according to an embodiment of this application is as follows: When the water level in the collection tank rises, the float 7 rises with the water level, and the float 7 will drive the slider 6 to slide upward along the slide rod 5; when the float 7 reaches the high water level, the rangefinder 14 will transmit a signal to the control switch to trigger the water pump 3 to start pumping water and sewage; when the water level drops, the float 7 will drive the slider 6 to slide downward, and the water pump 3 will continue to work until the float 7 reaches the low water level, and the rangefinder 14 will transmit a distance signal to the control switch to turn off the water pump 3; during the sliding of the slider 6, the roller 22 with bristles 21 and the scraper 19 will continuously scrape the outer surface of the slide rod 5 to remove impurities such as fibers, hair, and silt attached to the outer surface of the slide rod 5.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
