[0056] The optional embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0057] Example 1

[0058] In order to solve the problem that water pumps are prone to stalling in areas with heavy dust or weather conditions, this embodiment provides a water pump anti-sand system. Figure 1 Schematic diagram of a water pump anti-sand system provided by an embodiment of the present invention. Figure 1 As shown, the water pump anti-sand system comprises: a sedimentation tank 10. This embodiment does not limit the shape of the sedimentation tank, which can be a cylinder, a cuboid, etc.

[0059] An inlet 11 and an outlet 12 are provided at the upper portion of the sedimentation tank 10. The inlet 11 is connected to a water source through an inlet pipe, and the outlet 12 is connected to the water inlet end of the water pump 20 through an outlet pipe. Water from the water source enters the sedimentation tank 10 through the inlet 11, and sand and dust in the water 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 away from the inlet 11 to prevent the water (with sand and dust in the water) entering the sedimentation tank 10 from the inlet 11 from directly entering the water pump through the outlet 12. In a specific implementation, 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 are arranged opposite to each other. Preferably, the water 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 (containing sand and dust) entering the sedimentation tank 10 from the water inlet 11 from directly entering the water pump through the water outlet 12.

[0060] A sand filter 13 is provided at the middle and lower part of the sedimentation tank 10, and the sand and dust leak to the bottom of the sedimentation tank 10 through the sand filter 13. The leaked sand and dust are blocked by the sand filter 13 and are not easy to return to the top of the sand filter 13. The sand filter 13 is designed to be a structure that allows sand and dust to pass easily from top to bottom but not from bottom to top, so as to ensure that the sand and dust settle to the bottom for accumulation and are not easy to return to the top of the sand filter 13. The sand filter 13 is far away from the water outlet 12 to ensure the purification degree of the water near the water outlet 12 and prevent the sand and dust from being sucked into the water pump.

[0061] A stirring structure 14 is provided in the sedimentation tank 10 to disperse the sediment 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 provided in the sedimentation tank 10 for detecting the sand content in the sedimentation tank 10. When the sand content meets the preset conditions, the sand removal operation is performed through the stirring structure 14 and the sewage outlet 15. The sand content in the sedimentation tank 10 meets the preset conditions, indicating that the sedimentation tank 10 contains a lot of sand and needs to be desanded.

[0063] In the water pump sand prevention system of the present embodiment, a sedimentation tank 10 is arranged before the water inlet end of the water pump 20, and a sand filter net 13 is arranged in the middle and lower part of the sedimentation tank 10 away from the water outlet 12. The sand filter net 13 is a structure that is easy to enter and difficult to exit. The sand filter net 13 can effectively precipitate sand and dust in the water to prevent sand and dust from entering the water pump and causing the water pump to block. In addition, a stirring structure 14 and a detection device 16 are arranged in the sedimentation tank 10. When the detection device 16 detects that the sand content in the sedimentation tank 10 meets the preset conditions, the silt accumulated at the bottom of the sedimentation tank 10 is stirred up by the stirring structure 14 and discharged through the sewage outlet 15. The silt accumulated in the sedimentation tank is cleaned according to the actual sand accumulation situation, and intelligent sand removal is realized for the sedimentation tank, so as to avoid excessive silt accumulation in the sedimentation tank, facilitate subsequent sedimentation, and continuously ensure the sand prevention effect of the water pump, thereby solving the problem that the water pump is easy to block in areas or weather with heavy sand in the prior art, and realizing the purification of water quality before entering the water pump, thereby achieving better sand prevention and removal effect and avoiding water pump blockage.

[0064] The size of the sand filter net 13 matches the cross section of the sedimentation tank 10 , that is, the sand filter net 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 sand filter net 13 includes a plurality of sand filter units arranged in sequence. The sand filter units are hemispherical. With the vertex and center of the hemisphere as reference, the vertex direction of the hemisphere is above the sand filter net 13, and the center direction of the hemisphere is below the sand filter net 13. A first hole is opened at the vertex of the hemisphere, and a shielding component is arranged at the first hole in the direction of the center of the hemisphere to prevent the sand and dust leaking through the sand filter net 13 from returning to the top of the sand filter net 13. Second holes are formed between adjacent sand filter units. This embodiment does not limit the number and size of the sand filter units, the first holes and the second holes, and 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 can be achieved.

[0066] Based on the above-mentioned easy-in-but-difficult-to-exit sand filter structure, sand and dust can leak from the first hole and the second hole of the sand filter to the bottom and accumulate at the bottom. The sand and dust leaking through the sand filter is blocked by the sand filter and is not easy to return to the top of the sand filter, which can effectively precipitate the sand and dust in the water and prevent the sand and dust from entering the water pump and causing the water pump to jam.

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

[0068] refer to Figure 2 , is a partial schematic diagram of the sand filter, B represents the first hole, A represents the second hole, Figure 2 The folded edge at the first hole B is the shielding component. Of course, the shielding component can also be set in other styles, for example, Figure 2The folded edge shown is bent toward the center of the hemisphere, so that the first hole is similar to a funnel shape with a narrow lower end, which can also play a role in blocking sand and dust from moving upward.

[0069] Based on the sand filter structure of this embodiment, sand and dust can leak from the sand filter through the first hole and the second hole and accumulate at the bottom of the sedimentation tank. When the water pump is pumping water, there will be suction. In the sedimentation tank, the suction near the water outlet is the largest. As the distance from the water outlet increases, the suction decreases. The sand filter is far away from the water outlet, so the suction near the sand filter is small. When the water near the sand filter flows to the water outlet, the sand and dust near the sand filter rolls with the water flow. The sand filter is composed of multiple hemispherical sand filter units. When the sediment below the sand filter rolls, most of the sediment will be located in the hemisphere, and a small part of the sediment corresponds to the second hole. The first hole is provided with a shielding component, which has a blocking effect, so that the sediment is not easy to return to the top of the sand filter through the first hole, that is, most of the sediment is blocked. The second hole is similar to a funnel shape, which is wide at the top and narrow at the bottom. It is also not easy for the sediment to return to the top of the sand filter through the second hole. Sand is heavier than water. Even if a small amount of sediment returns to the top of the sand filter through the first hole and the second hole, it is easy to leak through the second hole again, making it easy to enter and difficult to exit. The sand and dust leaked through the sand filter is difficult to be directly pumped to the water pump to cause blockage.

[0070] The stirring structure 14 includes blades, which are connected to the motor through a motor shaft, and the blades are driven to rotate by the motor. The blades are located below the sand filter 13, and preferably, the blades are close to the bottom of the sedimentation tank 10. In this embodiment, the motor drives the blades to rotate, which can effectively disperse the silt accumulated at the bottom of the sedimentation tank.

[0071] As an example, Figure 3 As shown, the motor 141 is installed on the top of the sedimentation tank 10 to prevent sand and dust from affecting the operation of the motor 141. Specifically, the motor 141 can be installed in a waterproof housing to protect the motor. The blade 142 is coaxially connected to the motor 141, and the motor shaft passes through the sand filter 13. The sand filter 13 is provided with a hole at a corresponding position 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 the infrared receiver 162 are arranged opposite to each other on the side wall of the sedimentation tank 10, and are both located above the sand filter 13. When the infrared transmitter 161 and the infrared receiver 162 are turned on, if the proportion of the time that the infrared receiver 162 does not receive infrared waves within the preset time reaches the preset proportion, it is determined that the sand content meets the preset conditions. Among them, the preset time and the preset proportion can be set according to actual conditions. According to the size of the sedimentation tank and the penetration ability of infrared rays in water, a suitable infrared wavelength is selected to ensure that the infrared receiver can smoothly receive the infrared waves emitted by the infrared transmitter underwater without obstruction. For example, infrared rays with a wavelength of 700nm are selected. Figure 3The motor axis shown needs to be offset from the emission path of the infrared waves.

[0073] This embodiment uses infrared waves to effectively and reliably detect the sand content in the sedimentation tank, so as to start the sand removal operation at the appropriate time, disperse and discharge the silt accumulated at the bottom of the sedimentation tank, and ensure a continuous water pump anti-sand effect.

[0074] The detection device 16 can be turned on all the time, turned on periodically, or turned on when the accumulated value of sand removal reaches a preset threshold, wherein the accumulated value of sand removal is a predicted value obtained based on the length of time without sand removal and weather information for characterizing the degree of sand content in the sedimentation tank. The increase in the length of time without sand removal and bad weather will increase the sand content of the water entering the sedimentation tank, that is, increase the accumulated value of sand removal. The preset threshold can be set according to the actual situation. When the accumulated value of sand removal reaches the preset threshold, it means that the degree of sand content in the sedimentation tank 10 is likely to have met the preset conditions. At this time, the detection device 16 can be turned on for actual detection. In this embodiment, the detection device can be turned on based on the accumulated value of sand removal, which can avoid unnecessary turning on of the detection device and save energy consumption. The accumulated value of sand removal varies with the length of time without sand removal and weather information, taking into account the impact of weather conditions on water quality, and can more intelligently control the sand removal operation, optimize the frequency of sand removal, and realize intelligent sand removal, which is beneficial to prevent water pump blockage.

[0075] A partition 17 is provided in the sedimentation tank 10, located between the water inlet 11 and the water outlet 12, to prevent the water entering the sedimentation tank 10 from the water inlet 11 from directly entering the water pump 20 through the water outlet 12. One end of the partition 17 is located at the top of the sedimentation tank 10, and the other end of the partition 17 is located above the sand filter 13, and the partition 17 does not affect the operation of the detection device 16, so as to prevent the water entering the sedimentation tank 10 from directly entering the water pump 20 through the water outlet 12. Figure 3 In the example of using an infrared transmitter and an infrared receiver as the detection device 16, the partition 17 is located above the detection device 16 to avoid affecting the normal operation of the detection device 16. After the silt-containing water enters the sedimentation tank 10 through the water inlet 11, it is blocked by the partition 17 and first reaches the sand filter 13. Preferably, the partition 17 is close to the water inlet 11, which can achieve a better shielding and isolation effect.

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

[0077] The water pump sand prevention system also includes: a solid waste pool 30, which is located below the sedimentation tank 10, and the solid waste pool 30 is connected to the sewage outlet 15. A treatment port 31 for treating muddy water is provided at the lower part of the solid waste pool 30. In this embodiment, by providing a solid waste pool, muddy water can flow into the solid waste pool through the sewage outlet for treatment during the sand removal operation, thereby achieving environmental protection.

[0078] Preferably, the lower part of the waste solid pool 30 is set as an inclined surface, which is conducive to the flow of muddy water. The processing port 31 is located at the lower part of the inclined surface, which is convenient for processing muddy water.

[0079] A first filter screen 121 is disposed at the water outlet 12 , and 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 provided on the water outlet pipe. When the water pump 20 is running, the second valve 122 is opened. When the water pump 20 is shut down, the second valve 122 is closed. The second valve 122 can be used to control whether the sedimentation tank 10 supplies water to the water pump 20 .

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

[0082] A removable second filter 111 is also provided on the water inlet pipe. The second filter 111 may be a coarse filter to achieve preliminary filtration of the incoming water to prevent excessive sand and dust from entering the sedimentation tank 10. The second filter 111 may be removable, cleaned and replaced when dirty and blocked.

[0083] Example 2

[0084] This embodiment provides a water pump anti-sand control method, which is applied to the water pump anti-sand system described in the above embodiment. Figure 4 is a flow chart of a water pump anti-sand control method provided by an embodiment of the present invention, such as Figure 4 As shown, the method comprises the following steps:

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

[0086] S402, when the sand content meets the preset conditions, the water pump is turned off and the water inlet to the sedimentation tank is stopped, and the stirring structure and the sewage outlet are turned on to perform sand removal operations.

[0087] The present embodiment is based on the aforementioned water pump sand prevention system, in which a sedimentation tank is arranged before the water inlet end of the water pump, and a sand filter net is arranged in the middle and lower part of the sedimentation tank away from the water outlet, the sand filter net is a structure that is easy to enter and difficult to exit, and can effectively precipitate sand and dust in the water based on the sand filter net to prevent sand and dust from entering the water pump and causing the water pump to jam, and a stirring structure and a detection device are arranged in the sedimentation tank, and when the detection device detects that the sand content in the sedimentation tank meets the preset conditions, the water pump is turned off and the water inlet to the sedimentation tank is stopped, the stirring structure and the sewage outlet are opened to perform the sand removal operation, the silt accumulated at the bottom of the sedimentation tank is stirred up and discharged, and the silt accumulated in the sedimentation tank is cleaned according to the actual sand accumulation situation, so as to realize intelligent sand removal of the sedimentation tank, avoid excessive silt accumulation in the sedimentation tank, facilitate subsequent sedimentation, and continuously ensure the sand prevention effect of the water pump, thereby solving the problem that the water pump is easy to jam in areas or weather with heavy sand and dust in the prior art, and realizing the purification of water quality before entering the water pump, thereby achieving better sand prevention and removal effect and avoiding water pump jam.

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

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

[0090] Periodically opening the detection device to detect the sand content in the sedimentation tank;

[0091] When the sand removal cumulative value reaches a preset threshold, the detection device is turned on to detect the sand content in the sedimentation tank, wherein the sand removal cumulative value is a predicted value obtained based on the length of time without sand removal and weather information for characterizing the sand content in the sedimentation tank, and after each sand removal operation is performed, the sand removal cumulative value and the length of time without sand removal are cleared and recalculated.

[0092] This embodiment can turn on the detection device based on the sand removal cumulative value, which can avoid unnecessary turning on the detection device and save energy. The sand removal cumulative value varies with the length of time without 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, realize intelligent sand removal, and help prevent water pump blockage.

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

[0094] Step 1, starting from the moment when the sand removal operation was last performed, each time a preset time t is increased, the number n of t included in the current non-sand removal time is re-determined, and the product of n and the first weight is calculated to obtain a first value;

[0095] Step 2, obtaining the weather information of the most recent t and the weight 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, the greater the sandstorm level, the greater the fourth weight corresponding to the sandstorm level;

[0096] Step 3, respectively calculating the product of the wind force level at each t and its corresponding second weight, the product of the rainfall intensity at each t and its corresponding third weight, and the product of the sandstorm level at each t and its corresponding fourth weight within the current non-sand removal time, and adding them up to obtain a second value;

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

[0098] Among them, the preset duration t can be set according to the actual situation, for example, 6 hours, 12 hours, 1 day, etc. Specifically, the weights corresponding to different wind force levels, rainfall intensities and sandstorm levels can be set through experiments. During the process of water filling the sedimentation tank, the cumulative value of sand removal needs to be continuously calculated and updated. If the water pump stops running according to user needs, when a certain water level is reached in the sedimentation tank, the sedimentation tank also stops filling with water, and the sand content in the sedimentation tank does not change afterwards, so the cumulative value of sand removal can be stopped from being calculated.

[0099] This embodiment can timely update the sand removal cumulative value according to weather information and the length of time without sand removal. The sand removal cumulative value is gradually accumulated. When the sand removal cumulative value reaches the preset threshold, the detection device can be turned on, thereby considering the impact of weather conditions on water quality and realizing intelligent control and optimization of sand removal frequency. In addition, corresponding weights are set for different factors (such as the length of time without sand removal, wind force level, rainfall intensity, and sandstorm level), which improves the reliability and accuracy of sand removal cumulative value calculation.

[0100] For example, taking an air conditioning unit including a water pump as an example, the mainboard of the unit 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 counted in the database. The preset duration is 1 day, and the calculation formula of the sand removal cumulative value is as follows: Among them, M n represents the cumulative value of sand removal, n represents the number of days without sand removal, f represents the first weight, A i represents the wind force level on the i-th day, k i represents the second weight corresponding to the wind force level on the i-th day, B i represents the rainfall intensity on the i-th day, j i represents the third weight corresponding to the rainfall intensity on the i-th day, C i represents the sandstorm level on the i-th day, r iIndicates the fourth weight corresponding to the sandstorm level on the i-th day. When the accumulated sand removal value reaches the preset threshold, it means that a lot of sand has been deposited under the sand filter. At this time, the detection device is turned on. If the detection device detects that the sand content in the sedimentation tank meets the preset conditions, the unit mainboard issues a sand removal instruction and performs the sand removal operation. The unit mainboard can communicate with the user terminal (such as a mobile phone, etc.) and send the relevant information of sand removal to the user terminal for the user to understand and view.

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

[0102] The preset threshold is pre-set. When the accumulated sand removal 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, that is, a fixed sand removal time is used. The first set time, the second set time and the third set time can be set according to actual conditions.

[0103] This embodiment can effectively remove the accumulated sand in the sedimentation tank by controlling the stirring structure and the first valve.

[0104] For example, when the sand removal operation needs to be performed, the main board of the unit turns off the air conditioning unit, disconnects the power supply of the water pump, stops the water pump from pumping water, stops the water inlet to the sedimentation tank, starts the stirring structure after 10 seconds and opens the first valve at the bottom of the sedimentation tank at the same time, and the sediment accumulated at the bottom of the sedimentation tank is stirred into muddy water by the stirring structure and flows into the waste solid pool. 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 inlet to the sedimentation tank is turned on to remove the residual dirty water. After 1 minute, the first valve is closed to complete the sand removal. After the sand removal is completed, the air conditioning unit and the water pump are turned on.

[0105] This embodiment is based on a special sand filter net structure that can effectively prevent sand and dust in the sedimentation tank from being drawn into the water pump. Weather information and sand removal information are counted in a database to calculate the cumulative sand removal value. The sand removal action is intelligently controlled based on the cumulative sand removal value and the detection device to achieve better sand prevention and removal effects, and the water quality is purified before entering the water pump, effectively avoiding water pump blockage.
