Description

Technical Field

[0001] This invention belongs to the field of aquaculture tank technology, and in particular relates to an intelligent self-cleaning tank and its usage method. Background Technology

[0002] Currently, open or covered water troughs are generally used to supply water to cattle. However, the cleaning of these troughs still relies on manual labor. The method of manual cleaning is to drain all the water from the trough and then clean the dirt at the bottom. This wastes a whole trough of water every time the trough is cleaned. In recent years, farms have been facing a shortage of human resources, and the cost of labor has been increasing year by year. If management is not in place, the troughs will not be cleaned in time, and bacteria and pathogens will grow in the troughs, affecting the quality of drinking water for cattle, thereby reducing cattle productivity and causing diseases. This passively increases the mortality rate of farms and causes losses to farm profits.

[0003] Therefore, there is a need for an intelligent self-cleaning water trough and its usage method. The self-cleaning mechanism can scrape and push the sediment and floating matter in the water trough to the sewage discharge mechanism, thereby achieving timely cleaning of the water trough, reducing labor and water resource costs, ensuring clean drinking water for cattle, and improving the efficiency of the ranch.

[0024] The control module is located inside the side box. The control module includes a controller, a motor driver, a wireless communication module connected to the controller, and a monitoring terminal connected to the wireless communication module. The input terminal of the motor driver is connected to the output terminal of the controller, and the output terminal of the motor driver is connected to the input terminal of the drive motor.

The temperature sensor, pH sensor, turbidity sensor, low water level sensor, high water level sensor, left limit sensor, and right limit sensor are all connected to the input terminal of the controller. An alarm is connected to the output terminal of the controller.

[0025] Meanwhile, this invention also discloses a method for using a rationally designed intelligent self-cleaning sink, characterized by the following steps:

[0026] Step 1: Filling the water tank with water:

[0027] Step 101: The controller controls the water inlet solenoid valve to open or operates the manual water inlet valve to open, and water is supplied to the water tank body through the water inlet main pipe, water inlet meter, water inlet solenoid valve or manual water inlet valve, water inlet tee and water inlet pipe;

[0028] Step 102: During the process of filling the water tank, when the high water level sensor detects in real time and outputs a high water level signal to the controller, the controller controls the water inlet solenoid valve to close or operates the manual water inlet valve to close, thus stopping the water filling.

[0029] Step 2: Real-time monitoring of the water level inside the tank:

[0030] Step 201: During the process of filling the water tank with water for the cattle to drink, the temperature sensor, pH sensor and turbidity sensor detect the temperature, pH and turbidity of the water in the water tank and send the detected temperature, pH and turbidity values ​​to the controller.

[0031] Step 202: The controller compares the received temperature value with the water temperature requirement value. If the temperature value detected by the temperature sensor is less than the water temperature requirement value, the controller controls multiple electric heating plates to work to heat the water in the tank until the temperature value detected by the temperature sensor meets the water temperature requirement value.

[0032] Step 203: The controller compares the received pH value with the required pH value and the received turbidity with the required turbidity value. If the pH value does not meet the required pH value or the turbidity does not meet the required turbidity value, the controller will activate the alarm to sound an alarm.

[0033] Step 3: Self-cleaning of the water inside the sink:

[0034] When the water tank needs to be self-cleaned, the controller controls the drive motor to rotate. The rotation of the drive motor drives the scraper and filter screen to move along the inner tank of the water tank to clean the water tank.

[0035] During the process of cleaning the water in the tank body by moving the scraper and filter screen along the inner tank body, the scraper pushes the sediment in the bottom of the inner tank body to the bottom drain pipe, and the filter screen pushes the floating objects in the inner tank body to the top drain pipe.

[0036] At the same time, the controller opens the bottom drain valve and the top drain valve, and the sediment in the bottom is discharged with the water flow through the bottom drain pipe, the bottom drain valve, the tee pipe and the main drain pipe; the floating matter is discharged with the water flow through the top drain pipe, the top drain valve, the tee pipe and the main drain pipe.

[0037] The above method is characterized in that: in step three, the controller controls the drive motor to rotate, and the rotation of the drive motor causes the scraper and filter screen to move along the inner tank of the water tank body. The specific process is as follows:

[0038] Step A: The controller controls the drive motor to rotate forward via the motor driver. The forward rotation of the drive motor causes the traction rope to rotate around the drive wheel and the driven wheel. The rotation of the traction rope drives the scraper and filter screen to move to the left along the inner tank of the water tank body, close to the sewage discharge mechanism. The bottom of the scraper moves in contact with the bottom of the inner tank body. The drive body moves to the left along the top of the guide box via the upper guide wheel, and at the same time moves to the left along the bottom of the guide box via the lower guide wheel.

[0039] Step B: When the left limit sensor detects the driving body, the controller controls the drive motor to rotate in the opposite direction through the motor driver. The reverse rotation of the drive motor drives the scraper and filter screen to move to the right along the inner tank of the water tank body through the drive body. The drive body moves to the right along the top of the guide box through the upper guide wheel, and at the same time moves to the right along the bottom of the guide box through the lower guide wheel.

[0040] Step C: When the right limit sensor detects the driving body, the controller controls the drive motor to rotate in the forward direction through the motor driver, repeating steps A to B multiple times to realize the scraper and filter screen moving along the inner tank of the water tank body.

[0041] Compared with the prior art, the present invention has the following advantages:

[0042] 1. The present invention has a simple structure, reasonable design, and is easy to install and deploy.

[0043] 2. The present invention provides a water tank body comprising an inner tank, an outer tank, and an end plate. The inner tank is for holding water and facilitates the installation of the heating mechanism at the bottom of the outer tank. The outer tank is provided to be integrally formed with the inner tank, thereby achieving overall rigidity of the water tank body and facilitating the placement of the water tank body, thus improving stability.

[0044] 3. The heating mechanism in this invention is designed to heat the water contained in the water tank so that the temperature of the water meets the required water temperature and satisfies the drinking water temperature needs of cattle.

[0045] 4. The present invention is equipped with a drive motor so that the drive motor rotates to drive the traction rope to rotate around the drive wheel and the driven wheel. The rotation of the traction rope drives the scraper and filter screen to move along the inner tank of the water tank body through the drive body, thereby realizing cleaning along the length of the water tank body.

[0046] 5. The present invention provides a scraper and a filter screen so that, as the scraper and filter screen move along the inner tank of the water tank body, the scraper pushes the sediment at the bottom of the inner tank to the bottom drain pipe of the sewage discharge mechanism, and the filter screen pushes the floating matter in the inner tank to the top drain pipe of the sewage discharge mechanism for discharge.

[0047] 6. The method of using the intelligent self-cleaning sink of this invention is simple, convenient and easy to operate, and enables timely cleaning of the sink.

[0048] 7. The intelligent self-cleaning water trough of this invention is easy to operate and has good results. First, water is injected into the water trough body. Then, the water content in the water trough body is detected in real time and the water content in the water trough body is self-cleaned. It adapts to automatic water trough cleaning and timely water trough cleaning, reduces labor and water resource costs, and can ensure clean drinking water for cattle, thus improving the efficiency of the ranch.

[0049] In summary, this invention is reasonably designed and easy to operate. The self-cleaning mechanism scrapes and pushes sediment and floating matter in the water trough to the sewage discharge mechanism, thereby achieving timely cleaning of the water trough, reducing labor and water resource costs, ensuring clean drinking water for cattle, and improving farm efficiency.

[0142] like Figure 11 The method of using a smart self-cleaning sink, as shown, includes the following steps:

[0143] Step 1: Filling the water tank with water:

[0144] Step 101: Controller 16 controls the water inlet solenoid valve 2-7 to open or operates the manual water inlet valve 2-2 to open, and water is supplied to the water tank body 1 through the water inlet main pipe 2-8, water inlet meter 2-3, water inlet solenoid valve 2-7 or manual water inlet valve 2-2, water inlet tee 2-6 and water inlet pipe 2-1;

[0145] Step 102: During the process of filling water into the water tank body 1, when the high water level sensor 2-4 detects in real time and outputs a high water level signal to the controller 16, the controller 16 controls the water inlet solenoid valve 2-7 to close or operates the manual water inlet valve 2-2 to close, thus stopping the water filling.

[0146] Step 2: Real-time monitoring of the water level inside the tank:

[0147] Step 201: During the process of filling the water tank body with water for cattle to drink, temperature sensor 13, pH sensor 14 and turbidity sensor 15 detect the temperature, pH and turbidity of the water in the water tank body 1, and send the detected temperature value, pH value and turbidity value to controller 16.

[0148] Step 202: The controller 16 compares the received temperature value with the water temperature requirement value. If the temperature value detected by the temperature sensor 13 is less than the water temperature requirement value, the controller 16 controls multiple electric heating plates 7 to work to heat the water in the tank until the temperature value detected by the temperature sensor 13 meets the water temperature requirement value.

[0149] Step 203: The controller 16 compares the received pH value with the pH requirement value and the received turbidity with the turbidity requirement value. If the pH value does not meet the pH requirement value or the turbidity does not meet the turbidity requirement value, the controller 16 controls the alarm 20 to sound an alarm.

[0150] Step 3: Self-cleaning of the water inside the sink:

[0151] When it is necessary to clean the water in the tank body, the controller 16 controls the drive motor 5-1 to rotate. The rotation of the drive motor 5-1 drives the scraper 5-9 and the filter screen 5-8 to move along the inner tank body of the tank body 1 to clean the water in the tank body.

[0152] During the process of cleaning the water in the tank body 1 by moving the scraper 5-9 and the filter screen 5-8 along the inner tank body 1, the scraper 5-9 scrapes and pushes the sediment in the bottom of the inner tank body to the bottom drain pipe 6-1, and the filter screen 5-8 scrapes and pushes the floating matter in the inner tank body to the top drain pipe 6-2.

[0153] At the same time, the controller 16 controls the bottom drain valve 6-3 and the top drain valve 6-4 to open, and the sediment in the bottom is discharged with the water flow through the bottom drain pipe 6-1, the bottom drain valve 6-3, the tee pipe 6-5 and the main drain pipe 6-7; the floating matter is discharged with the water flow through the top drain pipe 6-2, the top drain valve 6-4, the tee pipe 6-5 and the main drain pipe 6-7.

[0154] In this embodiment, in step three, the controller 16 controls the drive motor 5-1 to rotate. The rotation of the drive motor 5-1 causes the scraper 5-9 and the filter screen 5-8 to move along the inner tank of the water tank body 1. The specific process is as follows:

[0155] Step A: Controller 16 controls drive motor 5-1 to rotate forward via motor driver 17. The forward rotation of drive motor 5-1 drives traction rope 5-4 to rotate around drive wheel 5-2 and driven wheel 5-3. The rotation of traction rope 5-4 drives scraper 5-9 and filter screen 5-8 to move to the left along the inner tank of the water tank body 1, close to the sewage discharge mechanism 6. The bottom of scraper 5-9 moves in contact with the bottom of the inner tank. The drive body moves to the left along the top of guide box 5-13 via upper guide wheel 5-121, and simultaneously moves to the left along the bottom of guide box 5-13 via lower guide wheel 5-122.

[0156] Step B: When the left limit sensor 11 detects the driving body, the controller 16 controls the drive motor 5-1 to rotate in the opposite direction through the motor driver 17. The reverse rotation of the drive motor 5-1 drives the scraper 5-9 and the filter screen 5-8 to move to the right along the inner tank of the water tank body 1 through the driving body. The driving body moves to the right along the top of the guide box 5-13 through the upper guide wheel 5-121, and at the same time moves to the right along the bottom of the guide box 5-13 through the lower guide wheel 5-122.

[0157] Step C: When the right limit sensor 12 detects the driving body, the controller 16 controls the drive motor 5-1 to rotate in the forward direction through the motor driver 17, repeating steps A to B multiple times to realize the movement of the scraper 5-9 and the filter screen 5-8 along the inner tank of the water tank body 1.

[0158] In this embodiment, the required water temperature is 15℃~25℃.

[0159] In this embodiment, the required pH value is 6.5 to 8.5; the required turbidity value is 1 NTU to 5 NTU.

[0160] In this embodiment, the water level inside the water tank is 2mm to 5mm higher than the top of the partition 8.

[0161] In summary, this invention is reasonably designed and easy to operate. The self-cleaning mechanism scrapes and pushes sediment and floating matter in the water trough to the sewage discharge mechanism, thereby achieving timely cleaning of the water trough, reducing labor and water resource costs, ensuring clean drinking water for cattle, and improving farm efficiency.

[0162] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the present invention. Any simple modifications, alterations, or equivalent structural changes made to the above embodiments based on the technical essence of the present invention shall still fall within the protection scope of the present invention.
