[0049] At present, pumping devices have been widely used in various industries, mainly for pumping various fluid media. These pumping devices are usually composed of a pump body and a power device, the pump body is equipped with pushing components such as impeller, gear or blade inside, and the output shaft of the power device is connected with the pushing components. By driving the rotation of the pushing components, the pumping device can effectively promote the flow of fluid. In most cases, the power source of the pumping device is a motor, and part of the motor also integrates a control board to realize the intelligent control function. However, it is worth noting that the motor and the control board will release a large amount of heat when working, and long-time continuous work will cause the temperature of the working environment to rise significantly, which poses a great challenge to the stable operation of the motor and the control board. Therefore, how to effectively cool the power device of the pumping device becomes a technical problem to be solved.

[0050] To solve the above technical problems, the embodiment provides a conveying pump 100, which can be used for pumping fluid medium.

[0051] With reference to Figures 1-14 The conveying pump 100 of the embodiment comprises a pump body 11 and a dual-shaft motor 12, the pump body 11 comprises a pump shell 112 and a pushing mechanism 111 installed in the pump shell 112, the pushing mechanism 111 is used for pushing liquid flow; the dual-shaft motor 12 comprises a motor shell 124, a motor body 122 and a controller 121 installed in the motor shell 124, the motor shell 124 is fixedly connected with the pump shell 112, the motor body 122 comprises a motor shaft 1221, one end of the motor shaft 1221 is connected with the pushing mechanism 111, and the other end is connected with a fan blade 123; the inside and outside of the motor shell 124 are exchanged by the rotation of the fan blade 123, so as to promote the heat dissipation of the motor body 122 and the controller 121.

[0052] Among them, the pump shell 112 is provided with a pump cavity, the pump shell 112 is provided with at least one liquid inlet interface 1121 and at least one liquid outlet interface 1122, the pushing mechanism 111 arranged in the pump shell 112 is driven to rotate by the dual-shaft motor 12, when the pushing mechanism 111 rotates, the fluid can be sucked from the liquid inlet interface 1121 by using the suction and extrusion mode, and the sucked fluid is pushed to the liquid outlet interface 1122 and then extruded, thereby realizing the function of conveying fluid. Among them, the pushing mechanism 111 can be reasonably selected according to the actual application scene, which can be but is not limited to the form of impeller, blade, gear, etc., and the form of the pump cavity formed in the pump shell 112 also needs to be correspondingly arranged according to the specific form of the pushing mechanism 111.

[0053] The double-shaft motor 12 is integrated with a controller 121, which is electrically connected with the motor body 122, and can control the power supply to the motor body 122, so as to control the rotation speed and rotation direction of the motor body 122, and realize the automatic control of the working of the conveying pump.

[0054] The motor body 122 of the double-shaft motor 12 comprises a motor shaft 1221, the two ends of the motor shaft 1221 are connected with the pushing mechanism 111 and the fan blade 123 respectively, when the motor shaft 1221 rotates, it will drive the pushing mechanism 111 and the fan blade 123 to rotate, the rotation of the pushing mechanism 111 can push the flow circulation, and the rotation of the fan blade 123 can drive the air flow.

[0055] In the traditional motor structure, a large amount of heat will be generated when the coil rotates, and a large amount of heat will also be generated when the control board works, in order to avoid the excessive accumulation of heat and cause the temperature to be too high, the traditional motor can only separate the installation of the motor body 122 part and the control board, and the two need to provide independent protection shell structures. In the structure of the double-shaft motor 12 of the present scheme, the motor body 122 and the controller 121 share a motor shell 124, which can provide installation support and protection for the motor body 122 and the controller 121 at the same time, compared with the form of separate installation of the motor body 122 and the controller 121 in the traditional scheme, the integrated installation mode of the present scheme is more compact in structure and lower in cost. It should be noted that the integration of the motor body 122 and the controller 121 into the motor shell 124 in the present scheme is based on the reliable heat dissipation structure of the present scheme, that is, the rotation of the fan blade 123 drives the air exchange inside and outside the motor shell 124, which realizes the rapid removal of the working heat of the motor body 122 and the controller 121, and avoids the problem of excessive temperature caused by the accumulation of heat in the motor shell 124.

[0056] It can be understood that, in order to realize the air exchange inside and outside the motor shell 124, appropriate vent holes need to be arranged on the motor shell 124 to allow the air to enter and exit.

[0057] Based on the conveying pump 100 of the embodiment, the driving function is realized by driving the operation of the pushing mechanism 111 in the pump body 11 by the dual-shaft motor 12. In the structure of the dual-shaft motor 12 of the scheme, the motor body 122 and the controller 121 are arranged in the motor shell 124, and the fan blade 123 is connected to the end of the motor shaft 1221 away from the pump body 11. During the operation of the motor body 122, the fan blade 123 is driven to rotate in addition to driving the operation of the pushing mechanism 111. The rotation of the fan blade 123 blows the air in the motor shell 124 out, and the new air outside is replenished into the motor shell 124, realizing the circulation of the air in and out of the motor shell 124. The air flow carries away the heat generated by the operation of the motor body 122 and the controller 121, thereby realizing the effective heat dissipation of the motor body 122 and the controller 121.

[0058] In summary, in the scheme of the embodiment, the motor body 122 and the controller 121 are integrated into the motor shell 124, which has the advantages of compact structure, good safety, low cost and the like. At the same time, the dual-shaft motor 12 is adopted, the end of the motor shaft 1221 is connected to the fan blade 123, and the rotation of the motor shaft 1221 drives the rotation of the fan blade 123 to drive the exchange of air flow in and out, realizing the purpose of effectively promoting the heat dissipation of the motor body 122 and the controller 121, reducing the working environment temperature of the motor body 122 and the controller 121, ensuring the stability of the work, and improving the service life.

[0059] In an embodiment, referring to Figure 8 , the motor cavity 1243 is formed in the motor shell 124, the motor body 122, the controller 121 and the fan blade 123 are arranged in the motor cavity 1243, and the air outlet 12421 is communicated with the side of the motor cavity 1243 away from the pump shell 112; the air inlet cavity 1244 is formed between the motor shell 124 and the pump shell 112, the first air inlet 12411 is communicated with the side of the air inlet cavity 1244, and the motor cavity 1243 is communicated with the air inlet cavity 1244.

[0060] In this embodiment, the internal structure of the motor shell 124 is further optimized to ensure more efficient and more direct heat dissipation effect.

[0061] Specifically, the motor shell 124 is internally divided into a motor cavity 1243 for accommodating the motor body 122, the controller 121 and the fan blade 123. The motor cavity 1243 not only protects the internal components, but also provides a relatively closed environment for heat management. It is worth noting that the side of the motor cavity 1243 facing away from the pump shell 112 is provided with an air outlet 12421, which allows the heated air to be effectively cooled and smoothly discharged from the motor shell 124.

[0062] Importantly, the motor shell 124 and the pump shell 112 form an air inlet cavity 1244. The air inlet cavity 1244 is connected to the outside through a first air inlet 12411 on the side, providing a continuous supply of cold air to the motor cavity 1243. The motor cavity 1243 and the air inlet cavity 1244 are connected by a communication passage, which allows cold air to be blown directly into the motor cavity 1243 along the axial direction and accurately towards the motor body 122. This design ensures that the air can be directly blown into the coil of the motor body 122. Since the coil is the main part of the motor that generates heat, this direct blowing method can more quickly and effectively remove the heat from the coil.

[0063] In summary, this embodiment allows air to enter the air inlet cavity 1244, blow into the motor cavity 1243 along the axial direction, and then blow axially towards the motor body 122. This direction allows the air to flow into the coil of the motor body 122, more quickly and directly removing the heat generated by the coil. Then the air is blown out from the air outlet 12421 away from the air inlet cavity 1244, achieving efficient and direct heat dissipation.

[0064] In addition, the air inlet cavity 1244 provided between the motor shell 124 and the pump shell 112 can also provide sufficient space for the connection of the motor shaft 1221 and the pushing mechanism 111, ensuring the reliability of the connection of the motor shaft 1221 and the pushing mechanism 111.

[0065] In one embodiment, in combination Figure 11 The motor cavity 1243 and the air inlet cavity 1244 are separated by a motor bottom plate 12413. The motor body 122 includes a stator assembly 1222 and a rotor assembly 1223. The rotor assembly 1223 includes a coil. The stator assembly 1222 is fixed to the motor bottom plate 12413. The rotor assembly 1223 is sleeved around the stator assembly 1222 and spaced apart from the motor bottom plate 12413. The motor bottom plate 12413 is provided with a first air passage 12412 that communicates the motor cavity 1243 and the air inlet cavity 1244. The first air passage 12412 is aligned with the rotor assembly 1223.

[0066] The motor body 122 is composed of a stator assembly 1222, a rotor assembly 1223, and a motor shaft 1221. The stator assembly 1222 is firmly fixed to the motor base plate 12413, while the rotor assembly 1223 is sleeved around the outer periphery of the stator assembly 1222. The motor shaft 1221 is fixedly connected to the rotor assembly 1223. When powered, the rotor assembly 1223 rotates relative to the stator assembly 1222, driving the motor shaft 1221 to rotate synchronously. In this solution, first air holes 12412 are carefully arranged on the motor base plate 12413. These holes are precisely aligned with the rotor assembly 1223. Since the coils in the rotor assembly 1223 are the main part of the motor that generates heat, this alignment design ensures that the cold air entering from the air inlet chamber 1244 can be blown directly onto the coils, thereby more effectively removing heat.

[0067] During specific implementation, an axial hole that allows the motor shaft 1221 to pass through needs to be provided on the motor base plate 12413 , so that the motor shaft 1221 can extend into the air inlet cavity 1244 to connect with the pushing mechanism 111 .

[0068] In one embodiment, combining Figure 10 The motor cavity 1243 and the air inlet cavity 1244 are separated by a motor base plate 12413 , and a first air hole 12412 connecting the motor cavity 1243 and the air inlet cavity 1244 is provided on the motor base plate 12413 .

[0069] A first air hole 12412 is provided on the motor base plate 12413 to meet ventilation requirements, so that the air in the air inlet cavity 1244 can smoothly enter the motor cavity 1243.

[0070] In one embodiment, the motor body 122 includes a stator assembly 1222 and a rotor assembly 1223, the rotor assembly 1223 includes a coil, the stator assembly 1222 is fixed to the motor base plate 12413, the rotor assembly 1223 is sleeved on the outer periphery of the stator assembly 1222 and is spaced apart from the motor base plate 12413, and the first air hole 12412 is aligned with the rotor assembly 1223.

[0071] The stator assembly 1222 is additionally provided with a reinforcing bottom plate 1224 on the side close to the motor bottom plate 12413. This design not only enhances the structural strength of the stator assembly 1222, but also facilitates the assembly between the stator assembly 1222 and the motor bottom plate 12413. Specifically, the reinforcing bottom plate 1224 can provide a larger connection area, which can be specifically set to have a larger cross-sectional area than the stator assembly 1222, so that it is more convenient to firmly and reliably fix the reinforcing bottom plate 1224 to the motor bottom plate 12413, such as by distributing a plurality of bolts for locking. The connection between the reinforcing bottom plate 1224 and the stator assembly 1222 can be by welding or bolting, so that the structure improves the structural strength of the stator assembly 1222 installation. During assembly, the stator assembly 1222 can be first fixedly connected with the reinforcing bottom plate 1224, and then the reinforcing bottom plate 1224 is fixed to the motor bottom plate 12413 as a whole. This way not only improves the assembly efficiency, but also enhances the reliability of the connection between the stator assembly 1222 and the motor bottom plate 12413. In addition, this way also facilitates the disassembly and assembly of the motor main body 122 during maintenance, that is, only the reinforcing bottom plate 1224 needs to be removed, and the motor main body 122 can be disassembled.

[0072] The reinforcing bottom plate 1224 of the present scheme is provided with a second air passage corresponding to the first air passage 12412 on the motor bottom plate 12413. In this way, when the cold air enters the motor cavity 1243 from the air inlet cavity 1244 through the first air passage 12412, it can continue to pass through the second air passage on the reinforcing bottom plate 1224, further ensuring effective cooling of the stator assembly 1222 and the rotor assembly 1223.

[0073] In an embodiment, the motor bottom plate 12413 is provided with a support rib network 12416 on the side close to the motor cavity 1243, and the reinforcing bottom plate 1224 abuts against the support rib network 12416.

[0074] The support rib network 12416 is formed by a series of longitudinal and transverse intersecting ribs, which form a dense grid structure on the motor bottom plate 12413. When the reinforcing bottom plate 1224 is fixed to the motor bottom plate 12413, it will abut tightly on these support rib networks 12416, which ensures the stable connection between the reinforcing bottom plate 1224 and the motor bottom plate 12413.

[0075] In an embodiment, in combination with Figure 4 and Figure 9 , the motor housing 124 is provided with a second air inlet 12422 corresponding to the mounting position of the controller 121.

[0076] The second air inlet 12422 provides an additional heat dissipation channel for the controller 121. Since the controller 121 also generates heat during the operation of the motor, the cold air introduced through the second air inlet 12422 can directly blow on the controller 121 to help dissipate heat, so that the controller 121 can be kept at a relatively low operating temperature, thereby improving its operating efficiency and stability.

[0077] In an embodiment, the controller 121 is provided with a socket 1211, and the second air inlet 12422 is correspondingly arranged with the socket 1211 to allow an external connector to be plugged into the socket 1211 through the second air inlet 12422.

[0078] The design of the socket 1211 facilitates current transmission and signal transmission between the controller 121 and external devices. Specifically, through the socket 1211, the connectors of external power lines and signal lines can be plugged into the socket 1211 to achieve power supply to the controller 121 and the motor body 122, as well as signal transmission between the controller 121 and external devices. The controller 121 can exchange data and communicate with other electronic devices or systems, thereby realizing remote monitoring and control of the entire motor system. This design not only improves the intelligence of the system, but also provides users with a more convenient and flexible operation method.

[0079] In addition, the second air inlet 12422 on the motor housing 124 is directly used as a window to allow external connectors to pass through, meeting the needs of directly blowing air on the controller 121 and inserting external connectors for connection, while reducing the number of hole positions opened on the motor housing 124, which is conducive to improving the reliability of the motor housing 124 and the protection capability of the motor housing 124 for internal devices.

[0080] In an embodiment, in combination with Figures 12-14 A control protection cover 1212 is installed on the controller 121, and the control protection cover 1212 is provided with a plugging avoidance hole corresponding to the socket 1211.

[0081] The introduction of the control protection cover 1212 also improves the safety and reliability of the entire controller 121, which can prevent dust, moisture and other debris from entering the interior of the controller 121, thereby avoiding controller 121 failures or damage caused by environmental factors. The plugging avoidance hole provided on the control protection cover 1212 allows external connectors to be smoothly plugged into the socket 1211 when needed without being hindered by the control protection cover 1212, ensuring the convenience of connection and ensuring that the controller 121 can normally communicate and exchange data with external devices while being protected.

[0082] In a specific implementation, sealing measures such as sponge pads or rubber pads are used around the socket 1211 and between the control protection cover 1212 to improve dust and water resistance. In a specific configuration, sufficient clearance should be reserved between the control protection cover 1212 and the edge of the second air inlet 12422 to provide the required air intake.

[0083] In one embodiment, the control protection cover 1212 is provided with heat dissipation fins 12121 .

[0084] Specifically, when the controller 121 generates heat during operation, the heat is transferred to the control protection cover 1212 through heat conduction. The heat dissipation fins 12121 can quickly disperse the heat to a larger surface area and take the heat away through air convection.

[0085] In one embodiment, combining Figure 9 、 Figure 10 as well as Figure 12 A support frame 12415 is provided on the motor base plate 12413 , the periphery of the control protection cover 1212 is sealedly connected to the support frame 12415 , and the controller 121 is installed on the side of the control protection cover 1212 facing the motor base plate 12413 .

[0086] Support frame 12415 is securely mounted on motor base plate 12413, forming a recess of a certain depth. This recess perfectly accommodates any protruding electronic components that may be present on controller 121, thereby preventing damage to the components due to collision or squeezing during installation. The periphery of control protection cover 1212 and support frame 12415 are tightly fitted together via a sealed connection (e.g., using sealing strips, sealing rings, etc.), effectively preventing dust, moisture, and other debris from entering the interior of controller 121. This sealing design not only improves the protection level of controller 121 but also ensures its stable operation in harsh environments.

[0087] In general, the design of the support frame 12415 and the control protection cover 1212 in this embodiment together provide a stable, safe and sealed installation environment for the controller 121, thereby enhancing the reliability and durability of the controller 121.

[0088] In addition, the controller 121 is installed on the control protection cover 1212, which is conducive to the heat on the controller 121 being directly transferred to the control protection cover 1212 and directly dissipated by the control protection cover 1212. That is, this structure is conducive to optimizing the heat dissipation of the controller 121.

[0089] In one embodiment, the controller 121 is provided with a main control unit and an electrical adjustment unit.

[0090] The main control unit is the core part of the controller 121, which is responsible for processing various signals from the application inside and outside the system, and making decisions and controls according to the preset algorithm and logic. The main control unit usually has high computing power and stability, which can ensure that the motor system can run stably under various working conditions.

[0091] The electric control unit is the part of the controller 121 that is directly related to the motor, which is responsible for receiving instructions from the main control unit and controlling the speed, direction and power of the motor. The electric control unit usually has precise current and voltage control capability, which can realize precise control of the motor, thereby improving the efficiency and performance of the motor system.

[0092] By integrating the main control unit and the electric control unit on the controller 121, comprehensive control and optimization of the motor system can be achieved. This design not only improves the integration and reliability of the system, but also makes the controller 121 more comprehensive and powerful.

[0093] In one embodiment, in combination Figure 3 The motor housing 124 includes a motor bottom shell 1241 and a motor cover 1242. The motor bottom shell 1241 is fixedly connected with the pump shell 112, and the motor cover 1242 covers the side of the motor bottom shell 1241 away from the pump shell 112. The air inlet cavity 1244 is formed between the motor bottom shell 1241 and the pump shell 112, and the motor cavity 1243 is formed between the motor cover 1242 and the motor bottom shell 1241.

[0094] The motor cover 1242 covers the side of the motor bottom shell 1241 away from the pump shell 112, forming a relatively closed space, i.e. the motor cavity 1243. The motor cavity 1243 is the main working area of the motor, which contains the stator assembly 1222, the rotor assembly 1223 and the controller 121 and other key components. The design of the motor cover 1242 not only protects these components from external environmental interference and damage, but also provides a relatively quiet and stable working environment for them.

[0095] At the same time, an air inlet cavity 1244 is formed between the motor bottom shell 1241 and the pump shell 112. The design of the air inlet cavity 1244 is to introduce cold air to help the motor and the pump dissipate heat. The cold air can enter the air inlet cavity 1244 through the air inlet on the motor housing 124, then flow through the heat dissipation area of the motor, and finally be discharged through the air outlet 12421.

[0096] In an embodiment, the motor bottom shell 1241 comprises a motor bottom plate 12413 and a bottom plate surrounding wall 12414 arranged around the periphery of the motor bottom plate 12413, the bottom plate surrounding wall 12414 extends to the side where the pump shell 112 is located and is connected to the pump shell 112, and the first air inlet 12411 is arranged on the bottom plate surrounding wall 12414 and / or the air outlet 12421 is arranged on the motor cover 1242.

[0097] The motor bottom plate 12413 is the planar part of the motor bottom shell 1241, which provides a mounting platform for the motor main body 122 and the controller 121, etc., and the bottom plate surrounding wall 12414 is a vertical wall surface arranged around the periphery of the motor bottom plate 12413, which extends to the side where the pump shell 112 is located and is tightly combined with the pump shell 112 through fixed connection (such as bolt connection, welding, etc.). This design not only enhances the connection strength between the motor bottom shell 1241 and the pump shell 112, but also forms a relatively closed space (i.e. the air inlet cavity 1244) and provides protection for the connection structure of the motor shaft 1221 and the pump body 11.

[0098] In an embodiment, it further comprises an air inlet shroud 131, which is installed on the motor shell 124 corresponding to the side of the first air inlet 12411, and an air distribution interval 1312 is formed between the air inlet shroud 131 and the motor shell 124, and a third air inlet 1311 is arranged on the air inlet shroud 131, and the third air inlet 1311 is arranged in a staggered manner with the first air inlet 12411.

[0099] Specifically, during operation, external air enters through the third air inlet 1311, passes through the air distribution interval 1312, and then enters the air inlet cavity 1244 through the first air inlet 12411. This structure can ensure the uniformity and stability of the airflow, and can also block the dust entering through the third air inlet 1311, i.e. the dust entering the air distribution interval 1312 through the third air inlet 1311 will impact the motor shell 124, preventing the dust from entering the air inlet cavity 1244 through the first air inlet 12411 again.

[0100] In an embodiment, it further comprises a pump base 13, and the pump body 11 and the dual-shaft motor 12 are integrally installed on the pump base 13.

[0101] The introduction of the pump base 13 provides additional stability and convenience for the installation of the pump body 11 and the dual-shaft motor 12. The pump base 13 is a specially designed structural member that is used to carry and fix the pump body 11 and the dual-shaft motor 12, ensuring that they can maintain stability and reliability during operation.

[0102] In an embodiment, in combination with Figure 3 and Figure 6The first air inlet 12411 is arranged on the bottom side of the motor shell 124, and the air inlet shroud 131 is arranged on the top side of the pump base 13.

[0103] The air inlet shroud 131 is combined into the structure of the pump base 13, so that the air inlet dustproof function is achieved, and the structure of the whole device is simplified. Importantly, the first air inlet 12411 is arranged on the bottom side of the motor shell 124, and the air inlet shroud 131 of the pump base 13 is arranged below the motor shell 124. The air inlet direction is from bottom to top. When the air enters through the third air inlet 1311, the dust carried by the air will hit the motor shell 124 upward, and then the dust will fall downward under the action of gravity, and then fall out of the third air inlet 1311 in the opposite direction. That is, this structure can achieve the effect of automatically discharging dust.

[0104] On the other hand, the embodiment also provides an irrigation system comprising the conveying pump.

[0105] The irrigation system of the embodiment is applied to agricultural irrigation, and the conveying pump can automatically pump irrigation water and liquid fertilizer to a specified position, so as to achieve the purpose of automatic irrigation.

[0106] Based on the conveying pump of the embodiment, the irrigation system of the embodiment has the advantage of long service life.
