DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-2 This application is described in further detail.

[0030] The embodiment of the present application discloses a fully automatic self-priming pump.

[0031] like Figure 1 As shown, the fully automatic self-priming pump includes a pump body 1, a motor 2 and a control component. Specifically, the pump body 1 has a water inlet 101, a water outlet and a drive port; the output end of the motor 2 is connected to the drive port of the pump body 1 to provide power for the pump body 1, so as to suck the well water or the water source connected through the water inlet pipe from the water inlet 101 of the pump body 1 and discharge it from the water outlet of the pump body 1; the control component includes a receiver and a controller, and the controller is simultaneously connected to the receiver and the motor 2 signal. The receiver can receive environmental information of the environment in which the pump body 1 is located, including but not limited to the water level in the well where the self-priming pump is located, the salt content of the pumped liquid, the current time or the local precipitation. The receiver processes the environmental information and compares it with the preset value, sends a signal to the controller according to the comparison result, and controls the working state of the motor 2 through the controller, thereby controlling the working state of the fully automatic self-priming pump.

[0032] like Figure 1As shown, in order to detect the water level in the environmental information, the fully automatic self-priming pump also includes a water level monitoring component, which is used to monitor the water level at the location of the pump body 1, that is, the water level in the well, and includes a pressure sensor 4, which is arranged at the bottom of the side end face of the pump body 1. The well water in the well directly acts on the diaphragm of the pressure sensor 4, causing the diaphragm to produce a micro-displacement proportional to the medium pressure, causing the resistance of the pressure sensor 4 to change. By detecting this change with an electronic circuit, and converting and outputting a standard signal corresponding to this pressure, the water pressure at the location of the pressure sensor 4 is obtained at this time. The built-in chip of the pressure sensor 4 can obtain the water depth at the location of the pressure sensor 4 at this time through the conversion formula of water pressure and water depth, and then obtain the real-time water level data in the well. The pressure sensor 4 transmits the real-time water level data in the well to the control component. After receiving the real-time water level data, the control component determines whether it is necessary to start the motor 2 to discharge the well water in the well or turn off the motor 2 to retain the well water in the well according to the preset water level range, thereby realizing automatic control of the pump body 1. In addition, the fully automatic self-priming pump also includes a base 3 as a supporting structure. The pump body 1 and the motor 2 are fixedly connected to the base 3, which ensures the stability and reliability of the full-automatic self-priming pump during operation.

[0033] like Figure 2 As shown, the pump body 1 is divided into a water inlet tank 103 and a water outlet tank 104 by a partition plate 105. The water inlet 101 is connected to the water inlet tank 103 for sucking water into the pump body 1; the water outlet is connected to the water outlet tank 104 for discharging the water in the water outlet tank 104 out of the pump body 1. A connecting port 106 connecting the water inlet tank 103 and the water outlet tank 104 is provided on the partition plate 105, so that water can flow from the water inlet tank 103 into the water outlet tank 104. An impeller 107 is provided in the water outlet tank 104, one end of which is matched with the connecting port 106, and the other end is matched with the driving port through the impeller shaft. When the motor 2 is started, the motor 2 drives the impeller shaft to rotate, and the impeller shaft drives the impeller 107 to rotate. The rotation of the impeller 107 causes the liquid at the impeller 107 to rotate along with the impeller 107. The rotating liquid will generate an outward centrifugal force, so that the liquid in the pump body 1 flows from the water inlet tank 103 to the impeller 107 through the connecting port 106, and from the impeller 107 to the water outlet tank 104. The water inlet 101 is used to replenish the liquid in the water inlet tank 103, and the water outlet is used to discharge the liquid in the water outlet tank 104.

[0034] like Figure 2As shown, in order to further improve the stability and service life of the fully automatic self-priming pump, the water inlet tank 103 is further divided into a clean water area 111 and a muddy water area 110 by a filter plate 108. The water inlet 101 is connected to the muddy water area 110, and the connecting port 106 is connected to the clean water area 111. A filter port connecting the clean water area 111 and the muddy water area 110 is provided on the filter plate 108, and a filter net 109 is provided at the filter port. When water enters the muddy water area 110 from the water inlet 101, the impurities therein will be intercepted by the filter net 109 in the muddy water area 110, and the clean water will flow into the clean water area 111 through the filter port, thereby ensuring the cleanliness of the water entering the water outlet tank 104 and preventing impurities from affecting the normal operation of the impeller 107.

[0035] There are multiple filter ports, which can allow the liquid in the muddy water area 110 to pass through the filter plate 108 more quickly into the clean water area 111, thereby improving the water intake efficiency of the self-priming pump. At the same time, the design of multiple filter ports also increases the interception area of ​​impurities and reduces the risk of clogging of a single filter port.

[0036] like Figure 2 As shown, in order to detect and control the flow, the fully automatic self-priming pump also includes a flow regulating component, which includes a plurality of electromagnetic flow valves 112 and a plurality of flow meters. The number of the electromagnetic flow valves 112 is the same as the number of the flow meters, and the number of the electromagnetic flow valves 112 is the same as the number of the filter ports. The electromagnetic flow valve 112 is arranged in the clean water area 111, one end of the electromagnetic flow valve 112 is connected to the filter port, and the other end of the electromagnetic flow valve 112 is connected to the clean water area 111. The flow meter is arranged at the electromagnetic flow valve 112 to detect the fluid flow passing through the flow valve, the flow meter is connected to the receiver signal, and the electromagnetic flow valve 112 is connected to the controller signal.

[0037] The receiver can obtain the real-time flow data of each electromagnetic flow valve 112 through the flow meter in real time, and compare it with the preset value, and send a signal to the controller according to the comparison result, so as to control the working state of the motor 2 and the opening of the electromagnetic flow valve 112 through the controller to adjust the total flow rate of the self-priming pump; at the same time, it can also judge the working state of the self-priming pump and whether there are abnormal conditions such as blockage at the filter port according to the comparison result. Once an abnormality is found, the receiver can control the motor 2 to stop running through the controller to prevent the filter port from being blocked by mud and sand, making it difficult for the liquid to flow from the muddy water area 110 to the clean water area 111, and the impeller 107 from idling, thereby affecting the stable operation of the self-priming pump.

[0038] like Figure 2As shown, the fully automatic self-priming pump also includes a salinity monitoring component, which includes a salinity sensor 113. The salinity sensor 113 is connected to the receiver signal. The salinity sensor 113 is arranged in the water outlet bin 104. The salinity sensor 113 is fixedly connected to the isolation plate 105. The salinity sensor 113 is arranged in the circumference of the connecting port 106 to detect the salinity of the water in the water outlet bin 104.

[0039] The salinity monitoring component can detect the salinity of the water in the water tank 104. The salinity sensor 113 sends the detected real-time salinity data to the receiver, which analyzes the real-time salinity data and compares it with the preset value. According to the comparison result, a signal is sent to the controller, which controls the working state of the motor 2 to prevent the water pumped by the self-priming pump from failing to meet normal usage requirements due to excessive salinity.

[0040] like Figure 1 and Figure 2 As shown, in order to utilize water with different salinities, the pump body 1 may have multiple water outlets, and the salinity monitoring component may also include multiple electromagnetic shut-off valves 102. The number of the electromagnetic shut-off valves 102 is the same as the number of the water outlets. One end of the electromagnetic shut-off valve 102 is connected to the water outlet, and the other end is used to connect to the water supply pipeline. The electromagnetic shut-off valve 102 is connected to the controller signal.

[0041] The salinity monitoring component can detect the salinity of the water in the water tank 104. The salinity sensor 113 sends the detected real-time salinity data to the receiver, which analyzes the real-time salinity data and compares it with the preset value. According to the comparison result, a signal is sent to the controller, and the controller controls the opening and closing of the electromagnetic shut-off valve 102, so that water with different salt contents can be delivered to different locations through different water supply pipelines to meet normal use requirements.

[0042] In order to notify the operator to promptly inspect and repair the fully automatic self-priming pump with problems, the control component can also include a warning light 5 and a transmitter, and the transmitter is used to connect the signal with the central control room. When the controller sends a signal to control the motor 2 to stop running, the warning light 5 starts, and the control component can also send a signal to the central control room through the transmitter to prompt the central control room to send staff for maintenance. After completing the maintenance, the staff can judge whether the fully automatic self-priming pump has returned to normal based on the warning light 5.

[0043] The implementation principle of a fully automatic self-priming pump in the embodiment of the present application is:

[0044] Select a working position, establish a remote connection between the central control room and the control components of the fully automatic self-priming pump, and set the working mode of the fully automatic self-priming pump by setting a preset value in the receiver, wherein the preset value can be the working time or the working duration.

[0045] The fully automatic self-priming pump is placed in the working position through the base 3, the drainage pipe or the irrigation water supply pipeline is connected to the multiple water outlets respectively, and then the fully automatic self-priming pump is started.

[0046] After the full-automatic self-priming pump is started, the motor 2 starts to work, the motor 2 drives the impeller shaft to rotate, and the impeller shaft drives the impeller 107 to rotate. The rotation of the impeller 107 causes the liquid at the impeller 107 to rotate along with the impeller 107. The rotating liquid will generate an outward centrifugal force, so that the liquid in the pump flows from the water inlet tank 103 to the impeller 107 through the connecting port 106, and from the impeller 107 to the water outlet tank 104. The water inlet 101 replenishes the liquid in the water inlet tank 103 at the same time, and the water outlet discharges the liquid in the water outlet tank 104 at the same time.

[0047] When the motor 2 is working, if the working position is in an underwater environment, the preset value may also include a water level range of the position, and the water level monitoring component monitors the real-time water level data of the position of the pump body 1, and the real-time water level data is transmitted to the receiver. After receiving the real-time water level data, the receiver determines whether to start the motor 2 to drain water or shut down the motor 2 to retain water according to the preset water level range, thereby realizing automatic control of the pump body 1.

[0048] While the motor 2 is working, if the preset value includes the liquid flow range, the fully automatic self-priming pump can simultaneously detect the real-time flow data of the electromagnetic flow valves 112 at multiple filter ports through multiple flow meters, and transmit the real-time flow data at each electromagnetic flow valve 112 to the receiver. After receiving the real-time flow data, the receiver adjusts the opening of the electromagnetic flow valve 112 according to the preset flow range. If all the electromagnetic flow valves 112 are opened to the maximum opening, the minimum liquid flow rate cannot be met, then the controller controls the motor 2 to stop running, and sends a signal to the central control room through the transmitter, prompting the central control room to send staff for maintenance, so as to avoid the filter port being blocked by mud and sand, making it difficult for the liquid to flow from the muddy water area 110 to the clean water area 111, and the impeller 107 idling, affecting the stable operation of the self-priming pump.

[0049] When the motor 2 is working, the liquid pumped by the fully automatic self-priming pump is a salty liquid, so the preset value can also include the salinity range of the liquid outlet, and the salinity monitoring component can detect the salinity of the water in the water tank 104. The salinity sensor 113 sends the detected real-time salinity data to the receiver, which analyzes the real-time salinity data and compares it with the preset value, and sends a signal to the controller according to the comparison result, and controls the opening and closing of the electromagnetic shut-off valve 102 through the controller, so that water with different salt contents can be sent to different locations through different water delivery pipelines to meet normal use requirements. If the detected real-time salinity data is greater than the maximum salinity, the controller controls the motor 2 to stop running, and sends a signal to the central control room through the transmitter, prompting the central control room that the water source has been contaminated and sending staff to check.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
