Technical Field

[0001] This invention relates to the field of water pump sand control technology, and more specifically, to a water pump sand control system, water pump sand control method, device, equipment, and medium. Background Technology

[0002] Water quality and the operating environment have a significant impact on the normal operation of water pumps. In high-altitude and desert regions (such as the Middle East), the weather is arid and sandstorms are frequent, resulting in a high sand content in the water, which can easily cause water pumps to become clogged.

[0003] Currently, simply installing a filter screen on the water pump's inlet pipe is ineffective at removing sand and still easily leads to pump blockage. Summary of the Invention

[0015] Optionally, the detection device may be continuously turned on, periodically turned on, or turned on when the cumulative sand removal value reaches a preset threshold, wherein the cumulative sand removal value is a predicted value obtained based on the duration of no sand removal and weather information to characterize the sand content in the sedimentation tank.

[0016] Optionally, a baffle is provided in the sedimentation tank, located between the inlet and the outlet, to prevent water entering the sedimentation tank from the inlet from directly entering the water pump through the outlet. One end of the baffle is located at the top of the sedimentation tank, and the other end of the baffle is located above the filter screen. The baffle does not affect the operation of the detection device.

[0017] Optionally, a first valve is provided at the sewage outlet.

[0020] Optionally, the water inlet is connected to a water inlet pipe, and a third valve and a removable second filter screen are provided on the water inlet pipe.

[0021] This invention also provides a water pump sand control method, applied to the water pump sand control system described in this invention, the method comprising:

[0022] Detect the sand content in the sedimentation tank;

[0023] When the sand content meets the preset conditions, the water pump is turned off and the water intake of the sedimentation tank is stopped. The stirring structure and the sewage outlet are turned on to perform the sand removal operation.

[0024] Optionally, the sand content in the sedimentation tank may be detected, including any of the following:

[0025] The detection device is kept running continuously to detect the sand content in the sedimentation tank;

[0026] The detection device is periodically turned on to detect the sand content in the sedimentation tank;

[0027] When the cumulative sand removal value reaches a preset threshold, the detection device is activated to detect the sand content in the sedimentation tank. The cumulative sand removal value is a predicted value obtained based on the duration of no sand removal and weather information to characterize the sand content in the sedimentation tank. After each sand removal operation, the cumulative sand removal value and the duration of no sand removal are reset to zero and recalculated.

[0028] Optionally, the method further includes:

[0029] Starting from the moment when the sand removal operation was last completed, for each additional preset time t, the number n of t contained in the current unremoved sand time is redefined, and the product of n and the first weight is calculated to obtain the first value;

[0030] Obtain the weather information for the most recent t and the weights of the weather information, wherein the weather information includes: wind force level, rainfall intensity and sandstorm level, the greater the wind force level, the greater the second weight corresponding to the wind force level, the greater the rainfall intensity, the greater the third weight corresponding to the rainfall intensity, and the greater the sandstorm level, the greater the fourth weight corresponding to the sandstorm level;

[0031] Calculate the product of wind force level and its corresponding second weight for each t within the current unremoved sand time, the product of rainfall intensity and its corresponding third weight for each t, ​​and the product of sandstorm level and its corresponding fourth weight for each t, ​​and sum them to obtain the second value;

[0032] The sum of the first value and the second value is calculated to obtain the latest cumulative sand removal value.

[0037] After the third set time, close the first valve.

[0038] This invention also provides a water pump sand control device, applied to the water pump sand control system described in this invention, the device comprising:

[0039] The detection module is used to detect the sand content in the sedimentation tank;

[0040] The sand removal module is used to shut off the water pump and stop the water inlet to the sedimentation tank when the sand content meets the preset conditions, and to open the stirring structure and the sewage outlet to perform the sand removal operation.

[0041] This invention also provides an electronic device, including: a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, it implements the water pump sand control method described in this invention.

[0042] This invention also provides a non-volatile computer-readable storage medium storing a computer program thereon, which, when executed by a processor, implements the water pump sand control method described in this invention.

[0043] By applying the technical solution of this invention, a sedimentation tank is set up before the water inlet of the water pump. A filter screen, located away from the outlet, is set up in the lower middle part of the sedimentation tank. The filter screen has a structure that makes it easy for sand to enter but difficult to exit. Based on the fact that the filter screen can effectively settle sand and dust in the water, it prevents sand and dust from entering the water pump and causing it to block. Furthermore, a stirring structure and a detection device are set up in the sedimentation tank. When the detection device detects that the sand content in the sedimentation tank meets the preset conditions, the stirring structure disperses the silt accumulated at the bottom of the sedimentation tank and discharges it through the sewage outlet. The silt accumulated in the sedimentation tank is cleaned according to the actual sand accumulation, realizing intelligent sand removal from the sedimentation tank. This avoids excessive silt accumulation in the sedimentation tank, facilitates subsequent sedimentation, and continuously ensures the sand prevention effect of the water pump. This solves the problem of water pumps easily blocking in areas or weather conditions with heavy sand and dust in the prior art. It realizes that the water quality is purified before entering the water pump, achieving a better sand prevention and removal effect and avoiding water pump blockage. Attached Figure Description

[0056] The optional embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0057] Example 1

[0058] To address the problem of water pumps easily clogging in areas with heavy sandstorms or in certain weather conditions, this embodiment provides a water pump sand prevention system. Figure 1 This is a schematic diagram of the water pump sand control system provided in an embodiment of the present invention, as shown below. Figure 1 As shown, the water pump sand control system includes a sedimentation tank 10. This embodiment does not limit the shape of the sedimentation tank; it can be a cylinder, cuboid, etc.

[0059] The sedimentation tank 10 has an inlet 11 and an outlet 12 at its upper part. The inlet 11 is connected to a water source via an inlet pipe, and the outlet 12 is connected to the inlet of the water pump 20 via an outlet pipe. Water from the source enters the sedimentation tank 10 through the inlet 11, where sand and dust settle to the bottom. Under the suction of the water pump 20, purified water near the outlet 12 enters the water pump 20. The outlet 12 is located away from the inlet 11 to prevent water (carrying sand and dust) entering the sedimentation tank 10 from the inlet 11 from directly entering the water pump through the outlet 12. In practice, both the inlet 11 and the outlet 12 can be located on the upper side wall of the sedimentation tank 10; for example, the inlet 11 and the outlet 12 can be positioned opposite each other. Preferably, the inlet 11 is located at the top of the sedimentation tank 10, and the incoming water flows downward, which can, to a certain extent, prevent the water entering the sedimentation tank 10 from the inlet 11 (which carries sand and dust) from directly entering the water pump through the outlet 12.

[0060] A filter screen 13 is installed in the lower middle part of the sedimentation tank 10. Sand and dust fall to the bottom of the sedimentation tank 10 through the filter screen 13. The fallen sand and dust are blocked by the filter screen 13 and do not easily return to the top of the filter screen 13. The filter screen 13 is designed so that sand and dust can easily pass through from top to bottom but not easily from bottom to top, to ensure that the sand and dust settle to the bottom and do not easily return to the top of the filter screen 13. The filter screen 13 is far away from the outlet 12 to ensure the purification level of the water near the outlet 12 and to prevent sand and dust from being sucked into the water pump.

[0061] A stirring structure 14 is provided inside the sedimentation tank 10 to disperse the sludge and sand accumulated at the bottom of the sedimentation tank 10. A sewage outlet 15 is provided at the bottom of the sedimentation tank 10, and the opening and closing of the sewage outlet 15 is controllable.

[0062] A detection device 16 is installed inside the sedimentation tank 10 to detect the sand content in the sedimentation tank 10. When the sand content meets the preset conditions, a sand removal operation is performed through the stirring structure 14 and the discharge port 15. If the sand content in the sedimentation tank 10 meets the preset conditions, it means that the sand content in the sedimentation tank 10 is too high, and sand removal is required.

[0063] In this embodiment, a sand-prevention system for water pumps includes a sedimentation tank 10 located before the inlet of the water pump 20. A filter screen 13, positioned away from the outlet 12, is installed in the lower middle part of the sedimentation tank 10. The filter screen 13 has a structure that allows sand to enter but not exit, effectively settling sand and dust in the water and preventing sand and dust from entering the water pump and causing blockage. A stirring structure 14 and a detection device 16 are installed inside the sedimentation tank 10. When the detection device 16 detects that the sand content in the sedimentation tank 10 meets the preset conditions, the stirring structure 14 disperses the silt accumulated at the bottom of the sedimentation tank 10 and discharges it through the drain outlet 15. The system cleans the silt accumulated in the sedimentation tank according to the actual sand accumulation, achieving intelligent sand removal from the sedimentation tank. This avoids excessive silt accumulation in the sedimentation tank, facilitates subsequent sedimentation, and continuously ensures the sand-prevention effect of the water pump. This solves the problem of water pumps easily becoming blocked in areas or weather conditions with heavy sand accumulation in the prior art. It achieves water purification before entering the water pump, resulting in better sand prevention and removal effects and preventing water pump blockage.

[0064] The size of the sand filter 13 is matched with the cross-section of the sedimentation tank 10, that is, the sand filter 13 covers the cross-section of the sedimentation tank 10, thereby ensuring the sedimentation effect of sand and dust as much as possible.

[0065] The filter screen 13 comprises multiple filter units arranged in sequence. Each filter unit is hemispherical, with the apex and center of the hemisphere as references. The apex of the hemisphere faces upwards, and the center faces downwards. A first hole is formed at the apex of the hemisphere, and a blocking component is provided at the first hole facing the center of the hemisphere to prevent sand and dust that has passed through the filter screen 13 from returning to the top of the filter screen 13. A second hole is formed between adjacent filter units. In this embodiment, the number and size of the filter units, the first hole, and the second hole are not limited. They can be specifically set according to the size of the sedimentation tank and the size of the sand and dust, as long as the effect of easy entry and difficult exit is achieved.

[0066] Based on the aforementioned filter screen structure that allows sand to enter but not exit, sand can leak through the first and second holes of the filter screen to the bottom and accumulate there. The sand that leaks through the filter screen is blocked by the screen and does not easily return to the top of the screen, effectively settling the sand in the water and preventing sand from entering the water pump and causing it to become clogged.

[0067] Preferably, the first hole is a concave area facing the center of the hemisphere, which is more conducive to the sedimentation of sand and dust.

[0068] refer to Figure 2 This is a partial schematic diagram of a sand filter screen, where B represents the first hole and A represents the second hole. Figure 2 The folded edge at point B of the first hole is the blocking component. Of course, the blocking component can also be set to other styles, for example... Figure 2The folded edge bends towards the center of the hemisphere, making the first hole resemble a funnel shape with a narrow bottom, which also helps to block sand and dust from moving upwards.

[0069] Based on the filter screen structure of this embodiment, sand and dust can leak down from the filter screen through the first and second holes and accumulate at the bottom of the sedimentation tank. When a water pump operates, it generates suction. In the sedimentation tank, the suction is strongest near the outlet and decreases with distance from the outlet. The filter screen is also far from the outlet, so the suction is weak near it. As water flows from the filter screen to the outlet, the sand and dust near the screen are agitated. The filter screen consists of multiple hemispherical filter units. When the sand and dust below the screen agitate, most of it is contained within the hemispheres, while a smaller portion corresponds to the second hole. The first hole has a blocking component, which prevents sand and dust from easily returning to the top of the screen. The second hole is funnel-shaped, wider at the top and narrower at the bottom, making it difficult for sand and dust to return to the top of the screen. Since sand is heavier than water, even if a small amount of sand and dust returns to the top of the screen through the first and second holes, it easily leaks back through the second hole, making it difficult for sand and dust to escape. Sand and dust leaking through the screen are difficult to pump directly to the water pump and cause blockage.

[0070] The stirring structure 14 includes blades, which are connected to a motor via a motor shaft. The motor drives the blades to rotate. The blades are located below the filter screen 13, preferably near the bottom of the sedimentation tank 10. In this embodiment, the motor-driven blade rotation effectively disperses the silt accumulated at the bottom of the sedimentation tank.

[0071] As an example, such as Figure 3 As shown, the motor 141 is installed on top of the sedimentation tank 10 to prevent sand and dust from affecting its operation. Specifically, the motor 141 can be installed in a waterproof housing to protect it. The blade 142 is coaxially connected to the motor 141, and the motor shaft passes through the filter screen 13. The filter screen 13 has holes at corresponding positions to provide a channel for the motor shaft to pass through.

[0072] The detection device 16 includes an infrared transmitter 161 and an infrared receiver 162. The infrared transmitter 161 and infrared receiver 162 are arranged opposite each other on the side wall of the sedimentation tank 10, both located above the filter screen 13. When the infrared transmitter 161 and infrared receiver 162 are turned on, if the proportion of time during which the infrared receiver 162 does not receive infrared waves reaches a preset ratio within a preset time, the sand content is determined to meet the preset conditions. The preset time and preset ratio can be set according to actual conditions. A suitable infrared wavelength is selected based on the size of the sedimentation tank and the penetrating power of infrared light in water to ensure that the infrared receiver can successfully receive the infrared waves emitted by the infrared transmitter underwater without obstruction; for example, an infrared wavelength of 700nm is selected. Figure 3The motor shaft shown needs to be offset from the infrared wave emission path.

[0073] In this embodiment, infrared waves are used to effectively and reliably detect the sand content in the sedimentation tank, thereby initiating the sand removal operation at the appropriate time to disperse and discharge the silt accumulated at the bottom of the sedimentation tank, ensuring the continuous sand prevention effect of the water pump.

[0074] The detection device 16 can be continuously activated, periodically activated, or activated when the accumulated sand removal value reaches a preset threshold. The accumulated sand removal value is a predicted value used to characterize the sand content in the sedimentation tank, obtained based on the duration of no sand removal and weather information. Increased duration of no sand removal and severe weather will increase the sand content of the sedimentation tank influent, thus increasing the accumulated sand removal value. The preset threshold can be set according to actual conditions. When the accumulated sand removal value reaches the preset threshold, it indicates that the sand content in the sedimentation tank 10 is highly likely to meet the preset conditions, at which point the detection device 16 can be activated for actual detection. This embodiment can activate the detection device based on the accumulated sand removal value, avoiding unnecessary activation of the detection device, saving energy. Furthermore, the accumulated sand removal value changes with the duration of no sand removal and weather information, taking into account the impact of weather conditions on water quality, enabling more intelligent control of the sand removal operation, optimizing the sand removal frequency, achieving intelligent sand removal, and facilitating pump anti-clogging.

[0075] A baffle 17 is installed inside the sedimentation tank 10, located between the inlet 11 and the outlet 12, to prevent water entering the sedimentation tank 10 from the inlet 11 from directly entering the water pump 20 through the outlet 12. One end of the baffle 17 is located at the top of the sedimentation tank 10, and the other end is located above the filter screen 13. The baffle 17 does not interfere with the operation of the detection device 16. Figure 3 Taking the infrared transmitter and receiver as the detection device 16 as an example, the partition 17 is located above the detection device 16 to avoid affecting its normal operation. After the sediment-laden water enters the sedimentation tank 10 through the inlet 11, it is blocked by the partition 17 and first reaches the filter screen 13. Preferably, the partition 17 is close to the inlet 11, which can achieve a better blocking and isolation effect.

[0076] A first valve 151 is installed at the sewage outlet 15. The first valve 151 is normally closed. When a sand removal operation is required, the first valve 151 is opened.

[0077] The water pump sand control system also includes a solid waste tank 30, located below the sedimentation tank 10. The solid waste tank 30 is connected to the sewage outlet 15, and a treatment outlet 31 for treating muddy water is provided at the lower part of the solid waste tank 30. In this embodiment, by setting up a solid waste tank, muddy water can be discharged into the solid waste tank through the sewage outlet for treatment during sand removal operations, thus achieving environmental protection.

[0078] Preferably, the lower part of the solid waste tank 30 is designed as an inclined surface, which facilitates the flow of sludge and water. The treatment port 31 is located at the lower part of the inclined surface, which facilitates the treatment of sludge and water.

[0079] A first filter screen 121 is installed at the water outlet 12. The water is filtered through the first filter screen 121 before flowing to the water pump, which can further prevent sand and dust from entering the water pump.

[0080] A second valve 122 is installed on the outlet pipe. When the water pump 20 is running, the second valve 122 is opened. When the water pump 20 is turned off, the second valve 122 is closed. The second valve 122 can control whether the sedimentation tank 10 supplies water to the water pump 20.

[0081] The inlet 11 is connected to the inlet pipe, and a third valve is installed on the inlet pipe. When the sedimentation tank 10 needs to be filled with water, the third valve is opened, and when the sedimentation tank 10 does not need to be filled with water, the third valve is closed. The third valve can control whether the sedimentation tank 10 is filled with water from the water source.

[0082] A removable second filter screen 111 is also installed on the water inlet pipe. The second filter screen 111 can be a coarse filter screen to achieve preliminary filtration of the incoming water and prevent excessive sand and dust in the water entering the sedimentation tank 10. The second filter screen 111 can be removed, cleaned and replaced when it is clogged.

[0083] Example 2

[0084] This embodiment provides a water pump sand control method, applied to the water pump sand control system described in the above embodiment. Figure 4 This is a flowchart of the water pump sand control method provided in the embodiments of the present invention, such as... Figure 4 As shown, the method includes the following steps:

[0085] S401, Detects the sand content in the sedimentation tank.

[0086] S402, when the sand content meets the preset conditions, turn off the water pump and stop the water inlet of the sedimentation tank, and turn on the stirring structure and the sewage outlet to perform the sand removal operation.

[0087] This embodiment, based on the aforementioned water pump sand prevention system, sets up a sedimentation tank before the water pump inlet. A filter screen, positioned away from the outlet, is installed in the lower middle part of the sedimentation tank. The filter screen has a structure that allows sand to enter but not exit, effectively settling sand and dust in the water and preventing sand and dust from entering the water pump and causing blockage. A stirring structure and a detection device are installed in the sedimentation tank. When the detection device detects that the sand content in the sedimentation tank meets preset conditions, the water pump is shut off and the water intake to the sedimentation tank is stopped. The stirring structure and drain are then activated to perform sand removal, dispersing and discharging the accumulated silt at the bottom of the sedimentation tank. Based on the actual sand accumulation, the accumulated silt in the sedimentation tank is cleaned, achieving intelligent sand removal from the sedimentation tank. This avoids excessive silt accumulation, facilitating subsequent sedimentation and ensuring the continuous sand prevention effect of the water pump. It solves the problem of water pumps easily blocking in areas or weather conditions with high sand and dust levels in existing technologies, achieving water purification before it enters the water pump, resulting in better sand prevention and removal effects and preventing water pump blockage.

[0088] In one embodiment, detecting the sand content in the sedimentation tank includes any of the following:

[0089] The detection device is kept running continuously to detect the sand content in the sedimentation tank;

[0090] The detection device is periodically turned on to detect the sand content in the sedimentation tank;

[0091] When the cumulative sand removal value reaches a preset threshold, the detection device is activated to detect the sand content in the sedimentation tank. The cumulative sand removal value is a predicted value obtained based on the duration of no sand removal and weather information to characterize the sand content in the sedimentation tank. After each sand removal operation, the cumulative sand removal value and the duration of no sand removal are reset to zero and recalculated.

[0092] This implementation method can activate the detection device based on the accumulated sand removal value, which can avoid unnecessary activation of the detection device, save energy, and the accumulated sand removal value changes with the duration of no sand removal and weather information, taking into account the impact of weather conditions on water quality. It can more intelligently control the sand removal operation, optimize the sand removal frequency, achieve intelligent sand removal, and help prevent water pump blockage.

[0093] In this embodiment, starting from the moment the sand removal operation was last completed, the cumulative sand removal value is updated every time the unremoved sand time increases by a preset time t. Specifically, the steps include:

[0094] Step 1: Starting from the moment when the sand removal operation was last completed, for each additional preset time t, redetermine the number n of t contained in the current unremoved sand time, and calculate the product of n and the first weight to obtain the first value;

[0095] Step 2: Obtain the weather information for the most recent t and the weight of the weather information. The weather information includes: wind force level, rainfall intensity and sandstorm level. The greater the wind force level, the greater the second weight corresponding to the wind force level. The greater the rainfall intensity, the greater the third weight corresponding to the rainfall intensity. The greater the sandstorm level, the greater the fourth weight corresponding to the sandstorm level.

[0096] Step 3: Calculate the product of wind force level and its corresponding second weight for each t within the current unremoved sand time, the product of rainfall intensity and its corresponding third weight for each t, ​​and the product of sandstorm level and its corresponding fourth weight for each t, ​​and sum them up to obtain the second value.

[0097] Step 4: Calculate the sum of the first value and the second value to obtain the latest accumulated sand removal value.

[0098] The preset duration 't' can be set according to actual conditions, such as 6 hours, 12 hours, or 1 day. The weights corresponding to different wind speed levels, rainfall intensities, and sandstorm levels can be determined experimentally. During the water intake process of the sedimentation tank, the accumulated sand removal value needs to be continuously calculated and updated. If the water pump stops operating according to user needs, and the sedimentation tank stops receiving water when it reaches a certain water level, the sand content in the sedimentation tank will not change afterward, so the accumulated sand removal value does not need to be calculated further.

[0099] This embodiment can update the cumulative sand removal value in a timely manner based on weather information and the duration of no sand removal. The cumulative sand removal value is gradually accumulated, and when the cumulative sand removal value reaches a preset threshold, the detection device can be activated. This takes into account the impact of weather conditions on water quality, thus realizing intelligent control and optimization of sand removal frequency. Furthermore, corresponding weights are set for different factors (such as the duration of no sand removal, wind force level, rainfall intensity, and sandstorm level), improving the reliability and accuracy of the cumulative sand removal value calculation.

[0100] For example, taking an air conditioning unit that includes a water pump as an example, the unit's mainboard is connected to the network to obtain weather information, and the sand removal information (i.e., the date and time of each sand removal operation) and weather information are statistically recorded in the database. The preset duration is 1 day, and the formula for calculating the cumulative sand removal value is as follows: Among them, M n This represents the cumulative value of sand removal, where n represents the number of days without sand removal, f represents the first weight, and A i k represents the wind force level on day i. i B represents the second weight corresponding to the wind force level on day i. i Let j represent the rainfall intensity on day i. i C represents the third weight corresponding to the rainfall intensity on day i. i R represents the dust storm level on day i. iThis represents the fourth weight corresponding to the sandstorm level on day i. When the accumulated sand removal value reaches the preset threshold, it indicates that a significant amount of silt has accumulated below the filter screen. At this point, the detection device is activated. If the detection device detects that the sand content in the sedimentation tank meets the preset conditions, the unit's main board issues a sand removal command to execute the sand removal operation. The unit's main board can communicate with user terminals (such as mobile phones) to send relevant sand removal information to the user terminal for easy understanding and viewing.

[0101] In one embodiment, activating the stirring structure and the drain outlet to perform a sand removal operation includes: activating a first valve at the stirring structure and the drain outlet; after a first set time, activating the stirring structure; after a second set time, activating the inlet water of the sedimentation tank; and after a third set time, activating the first valve.

[0102] The preset threshold is pre-set. When the accumulated sand value reaches the preset threshold, the amount of sand in the sedimentation tank is basically fixed. Therefore, the opening time of the stirring structure and the first valve can be fixed, i.e., a fixed sand removal time is used. The first, second, and third preset times can be set according to the actual situation.

[0103] This embodiment effectively removes accumulated sand from the sedimentation tank by controlling the stirring structure and the first valve.

[0104] For example, when a sand removal operation is required, the main board of the unit shuts down the air conditioning unit, disconnects the water pump power, stops pumping water, and stops the water intake to the sedimentation tank. After 10 seconds, the stirring structure is activated and the first valve at the bottom of the sedimentation tank is opened. The silt accumulated at the bottom of the sedimentation tank is dispersed into muddy water that flows into the waste solids tank. After 2 minutes, the stirring structure is turned off, and the remaining muddy water at the bottom of the sedimentation tank flows out. After 30 seconds, the water intake to the sedimentation tank is opened to remove residual dirty water. After 1 minute, the first valve is closed, completing the sand removal. After the sand removal is completed, the air conditioning unit and water pump are turned on.

[0105] This embodiment, based on a special sand filter structure, can effectively prevent sand and dust in the sedimentation tank from being drawn to the water pump. It collects weather information and sand removal information into a database to calculate the cumulative sand removal value. Based on the cumulative sand removal value and the detection device, it intelligently controls the sand removal action to achieve a better sand prevention and removal effect. It also realizes that the water quality is purified before entering the water pump, effectively avoiding water pump blockage.
