Description
Technical Field
[0001] The invention relates to the technical field of water pumps, and in particular to a circulating water pump structure. Background Art
[0002] Circulating water pump is a common type of water pump, widely used in the circulation system in the fields of industry, construction and agriculture. Its basic structure is designed to achieve efficient and reliable circulation and delivery functions. Circulating water pump is a common type of water pump, widely used in the circulation system in the fields of industry, construction and agriculture. Its basic structure is designed to achieve efficient and reliable circulation and delivery functions.
[0003] Common circulating water pumps have two technologies: one is to introduce variable frequency speed regulation technology, that is, to adjust the motor speed through the frequency converter to match different load conditions, so as to achieve the purpose of energy saving and consumption reduction; the other is to integrate intelligent control system to achieve real-time monitoring and control of the running status of the water pump, and further improve the overall performance of the system. Although these two technologies have improved the defects of the original products to a certain extent, they are poor in applicability and stability, especially for complex and changeable working conditions; In addition, the common circulating water pump adopts the plug-in method when connecting with the external water pipe. However, since the water outlet of the water pump has a large impact and pressure when discharging water, it is easy to cause the pipe joint to move and leak. In addition, since the water pipe at the water outlet of the water pump is easy to bend, the resistance of the water flow is increased, which cannot meet the working requirements of the water pump. Therefore, a circulating water pump structure is proposed. Summary of the invention 1. Technical issues to be resolved In view of the deficiencies of the prior art, the present invention provides a circulating water pump structure to solve the technical problems of poor applicability and stability, and easy displacement of pipe joints and leakage.
[0004] (II) Technical solution To achieve the above-mentioned purpose, the present invention provides the following technical solution: a circulating water pump structure, comprising: Base and infrastructure: A base frame is installed on the top right side of the base, providing a stable support platform for the entire water pump system; a high-performance electric motor is installed on the top right side of the base frame, serving as the driving core to provide power for the water pump; the left side of the motor is adjacent to the impeller chamber, which is the area where the water flow is accelerated and converted into circulating power; an intelligent monitoring unit is installed on the top of the motor to monitor and record the operating status of the water pump at all times; a frequency conversion controller is installed on the front side of the base frame, which can achieve precise control of the water pump flow by adjusting the speed of the motor.
[0005] Installation box and water pipe fixing system: The installation box is installed on the left side of the top of the base, and the left water outlet of the impeller chamber is closely connected to the water pipe to ensure smooth water flow; the left side of the installation box is connected with a cover plate by bolts, and the cover plate fits tightly with the installation box, which not only ensures the integrity of the structure, but also facilitates daily maintenance and repair. Clamp arms are installed on both sides of the installation box through high-precision bearings. These clamp arms are like flexible hands that can hold the water pipe tightly to prevent it from shaking during operation.
[0006] Clamping mechanism of the clamping block and the column: A clamping block is embedded in the middle of the inner side of the installation box and the cover plate, providing a stable support point for the column. The insert passes through the inside of the clamping block and is closely connected to the column to form a reliable fixing system. The top of the column is equipped with a lower clamping roller, which can ensure the stability of the water pipe during operation through pressure. The bevel edges of the triangular seats installed on the left and right sides of the column are set to face outward, which not only enhances the stability of the structure, but also can achieve a more flexible clamping effect by cooperating with the roller to drive the swing of the clamp arm when the column moves up and down.
[0007] Spring and base stabilization system: A base is installed at the bottom of the inner cavity of the installation box to provide support for the spring. The bottom end of the spring is closely connected to the top of the base. This design not only improves the stability of the spring installation, but also absorbs the vibration generated by the operation of the water pump to a certain extent, protecting the water pipe from damage.
[0008] Slide and slider adjustment mechanism: A trapezoidal slide and a matching slider are provided on the lower side of the base, which not only improves the stability of the slide, but also allows for flexible adjustment of the slider. The length of the slider is greater than the slide, ensuring that the slider can slide stably in the slide without falling off. A bracket is provided at the left end of the slider, tightly connecting the slider to the support seat. The design of the support seat can straighten the water pipe near the outlet section, reduce the resistance of the water flow, make the water flow smoother, and thus improve the working efficiency of the circulating water pump. At the same time, this design can also effectively prevent the water pipe from deforming and the joints from loosening under the condition of long-term water flow pressure and water pump vibration, thereby improving the overall quality and service life of the water pump.
[0009] Screw and gear adjustment system: A side plate is installed on the right side of the base frame, and a screw is inserted into the lower side of the base frame through a bearing. The left end of the screw is screwed to the inside of the slider, and the position of the slider can be accurately adjusted by rotating the screw. The length of the screw is the same as the slide slot, ensuring a smooth and stable adjustment process. At the right end of the screw, the first gear and the second gear are tightly meshed to form a flexible transmission system. A handwheel is installed on the right side of the second gear. By turning the handwheel, the second gear can be driven to rotate, and then the first gear drives the screw to rotate to achieve the left and right position adjustment of the slider and the bracket. This design enables the water pump to flexibly adjust the supporting position of the support seat to the water pipe according to different water flow requirements, thereby ensuring the best operation effect of the water pump under different working conditions.
[0010] (III) Beneficial effects Compared with the prior art, the present invention provides a circulating water pump structure, which has the following beneficial effects: 1. The circulating water pump structure receives the speed setting signal from the intelligent monitoring unit through the frequency conversion controller and adjusts the motor power supply frequency through the PWM pulse width modulation technology to control the impeller speed. The added intelligent monitoring unit can collect and analyze various operating parameters of the system and formulate the optimal working strategy, so that the circulating water pump can maintain the best working state in various complex environments, significantly reducing energy consumption, improving overall efficiency, and extending service life. The high degree of automation simplifies the need for manual intervention, which not only saves labor costs, but also improves the reliability and safety of the system; 2. The circulating water pump structure can achieve the movement of the column and the triangular seat by pressing the handle down, thereby expanding the clamp arm outward. When the water pipe is connected, the handle is released, so that the column and the triangular seat are pushed up under the action of the spring, and then the side clamping roller and the lower clamping roller are pressed tightly against the connection between the water pipe and the water pump outlet pipe, which can alleviate the stress and displacement caused by thermal expansion and contraction of the pipeline system, mechanical vibration during equipment operation and other external factors. At the same time, by adding a spring extrusion supporting structure at the connection of the water pump outlet pipe, the stability of the entire circulating water system can be enhanced, and the displacement caused by installation errors, pipeline deformation or foundation settlement can be compensated to a certain extent, thereby avoiding water leakage when the water pump is in use and improving the quality of water pump use.

DETAILED DESCRIPTION
[0013] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0014] The present invention provides a technical solution, a circulating water pump structure, including a base 1, a basic frame 2, a side plate 211, a motor 3, an impeller chamber 4, an intelligent monitoring unit 5, a frequency conversion controller 6, an installation box 7, a water pipe 8, a cover plate 9, a through groove 91, a clamping arm 10, a clamping block 11, a side clamping roller 12, an insert 13, a column 14, a lower clamping roller 15, a triangular seat 16, a matching roller 17, a handle 18, a base 19, a spring 20, a slide 21, a slider 22, a bracket 23, a supporting seat 24, a lead screw 25, a first gear 26, a second gear 27 and a handwheel 28: See also Figure 1 A basic frame 2 is installed on the top right side of the base 1. The basic frame 2 not only plays a supporting role, but also provides a stable foundation for the installation of subsequent components. A motor 3 is installed on the top right side of the basic frame 2. The motor 3 is the power source of the entire circulating water pump system and drives the operation of the entire system. An impeller chamber 4 is installed on the left side of the motor 3. The water flow in the impeller chamber 4 is accelerated and a circulating pressure is generated. An intelligent monitoring unit 5 is installed on the top of the motor 3 for constantly monitoring and optimizing the operating status of the water pump. A frequency conversion controller 6 is installed on the top front side of the basic frame 2; The frequency conversion controller 6 connects the intelligent monitoring unit 5 and the motor 3, receives the speed setting signal from the intelligent monitoring unit 5 through the frequency conversion controller 6, and adjusts the power supply frequency of the motor 3 through the PWM pulse width modulation technology: when working, through the frequency conversion controller 6, the system can receive the speed setting signal from the intelligent monitoring unit 5, and use the PWM (pulse width modulation) technology to accurately adjust the power supply frequency of the motor 3, thereby achieving fine control of the impeller speed, and the intelligent monitoring unit 5 will collect and analyze various operating parameters of the system when working, such as flow, pressure, temperature, etc., and formulate the optimal working strategy based on these data. This control method not only improves the response speed of the system, but also enables the circulating water pump to maintain the best working state in various complex environments, significantly reduces energy consumption, improves overall efficiency, and prolongs the service life of the equipment. The high degree of automation of this solution simplifies the need for manual intervention, which not only saves labor costs, but also improves the reliability and safety of the system; The installation box 7 is installed on the top left side of the base 1. The left water outlet of the impeller chamber 4 is connected with a water pipe 8. Figure 2 A cover plate 9 is installed on the left side of the installation box 7, and the cover plate 9 is tightly connected to the installation box body by bolts, which not only ensures the integrity of the structure, but also facilitates daily maintenance, and also ensures the stability and sealing of the entire structure; See also Figure 3 and Figure 4 , the left and right sides of the interior of the installation box 7 are equipped with clamping arms 10 through bearings, which provide stable support for the key components of the water pump; the clamping block 11 is installed in the middle of the inner side of the installation box 7 and the cover plate 9, and the inside of the clamping block 11 is inserted with an insertion strip 13, and the inner end of the insertion strip 13 is connected to a column 14, and the top of the column 14 is equipped with a lower clamping roller 15; the triangular seat 16 is installed on the left and right sides of the column 14 to enhance the stability and load-bearing capacity of the structure, and the top of the clamping arm 10 is inserted with a side clamping roller 12 through a bearing, which further improves the reliability and flexibility of pipeline fixing, please refer to Figure 5 A spring 20 is inserted inside the column 14, which not only enhances the elasticity of the structure but also effectively reduces the impact of vibration on the water pump components; The clamping arms 10 installed by bearings on both sides of the installation box 7 and the clamping blocks 11 installed in the middle of the inner side of the installation box 7 and the cover plate 9 together form a flexible clamping mechanism. The clever cooperation of the insert strip 13 and the column 14 enables the pressing roller 15 below and the pressing roller 12 on the side to be pressed tightly against the connection between the water pipe 8 and the water pump outlet pipe under the action of the spring 20. This solution can not only effectively alleviate the stress and displacement caused by thermal expansion and contraction of the pipeline system, mechanical vibration during equipment operation and other external factors, but also enhance the stability of the entire circulating water system through the extrusion support structure of the spring 20 to avoid water leakage when the water pump is in use.
[0015] See also Figure 1 , the four corners of the bottom of the base 1 are connected with corner blocks to increase the contact area with the ground and improve stability. Figure 2 The four inner corners of the cover plate 9 are connected to the corresponding positions on the left side of the installation box 7 by bolts. For the convenience of operation and maintenance, a through slot 91 is provided in the middle of the upper inner side of the cover plate 9. A handle 18 is connected to the upper left side of the column 14, and the handle 18 runs through the through slot 91, so that the staff can easily lift and lower the column 14. At the same time, the hypotenuse of the triangular seat 16 is set to face outward, which not only enhances the stability of the structure, but also avoids damage caused by uneven force.
[0016] See also Figure 4 The inner lower side of the clamp arm 10 is connected to a matching roller 17 through a bearing, which further improves the flexibility and durability of the structure. Figure 3 A base 19 is installed at the bottom of the inner cavity of the installation box 7, and the bottom end of the spring 20 is connected to the corresponding position of the top of the base 19. By tightly connecting the spring 20 and the base 19, additional buffering and support are provided for the entire structure. The movement of the column 14 and the triangular seat 16 is pressed down by the handle 18, so that the clamp arm 10 can be expanded outward. When the water pipe 8 is connected, the handle 18 is released, so that the column 14 and the triangular seat 16 are pushed up by the spring 20, and then the side clamping roller 12 and the lower clamping roller 15 can be pressed tightly against the connection between the water pipe 8 and the water pump outlet pipe, so as to achieve effective sealing operation and avoid loosening of the connection. At the same time, by adding a spring 20 to squeeze the supporting structure at the connection of the water pump outlet pipe 8, the stability of the entire circulating water system can be enhanced, and the displacement caused by factors such as installation errors, pipe deformation or foundation settlement can be compensated to a certain extent, avoiding water leakage when the water pump is in use, and improving the quality of the water pump. See also Figure 7 A slide groove 21 is provided on the lower inner side of the base 1, and a slider 22 is inserted on the left inner side of the slide groove 21, so that some parts of the water pump can be slid and adjusted within a certain range. The slide groove 21 and the slider 22 are both trapezoidal in shape, which not only ensures the stability of the structure but also facilitates the implementation of sliding adjustment. The length of the slider 22 is greater than the length of the slide groove 21, so that the slider 22 has a larger adjustment range in the slide groove 21. The left end of the slider 22 is connected to a bracket 23, and a support seat 24 is installed on the top of the bracket 23 to support and fix the key parts of the water pump.
[0017] See also Figure 6 The right side of the base frame 2 is connected to a side plate 211, see Figure 8, a lead screw 25 is inserted into the lower inner side of the side plate 211 through a bearing, and the left end of the lead screw 25 is screwed to the inside of the slider 22, so that the staff can accurately adjust the position of the slider 22 by rotating the lead screw 25. The length of the lead screw 25 is the same as that of the slide 21, ensuring the accuracy and stability of the adjustment. A first gear 26 is coaxially installed on the right end of the lead screw 25, and a second gear 27 is installed on the right side of the side plate 211 at a position above the first gear 26 through a bearing. The second gear 27 is meshed with the first gear 26, so that the staff can indirectly drive the rotation of the lead screw 25 by rotating the second gear 27. A hand wheel 28 is coaxially connected to the right side of the second gear 27, and a handle is installed on the periphery of the hand wheel 28, so that the staff can operate the entire adjustment mechanism more easily and conveniently. Through the clever cooperation of the slider 22, the bracket 23 and the supporting seat 24, the water pipe 8 near the water outlet section can be straightened, thereby reducing the resistance of the water flow and making the water flow smoother. This solution not only helps to improve the working efficiency of the circulating water pump, but also reduces the possibility of deformation and loosening of the connection of the curved water pipe under long-term water flow pressure and water pump vibration, further improving the quality of water pump use.
[0018] This solution achieves comprehensive optimization of the circulating water pump system through a series of precise designs and advanced control technologies. Whether it is the fine control achieved through the frequency converter 6 and the intelligent monitoring unit 5, or the stable clamping mechanism composed of the clamping arm 10, the clamping roller 12 and the spring 20, and the water pipe straightening design achieved through the slide 21, the bracket 23 and the supporting seat 24, all fully demonstrate the significant advantages of this solution in improving system efficiency, extending service life, and enhancing system stability and reliability.
[0019] The core of this solution is to receive the precise speed setting signal from the intelligent monitoring unit 5 through the frequency conversion controller 6, and use the advanced PWM pulse width modulation technology to dynamically adjust the power frequency supplied to the motor 3 to achieve fine control of the impeller speed. This solution ensures that the circulating water pump can flexibly adjust the working state according to actual needs and effectively respond to the working requirements of various complex environments.
[0020] The intelligent monitoring unit 5 can collect and deeply analyze various operating parameters of the water pump system in real time, such as pressure, flow, temperature and vibration, and can also formulate and implement the most optimized working strategy based on these data. This intelligent management method enables the circulating water pump to maintain the best operating state under any conditions, thereby greatly reducing energy consumption, improving overall operating efficiency, and significantly extending the service life of the equipment.
[0021] In addition, this solution also achieves a high degree of automated control, greatly simplifying the need for manual intervention, which can effectively save labor costs, while significantly improving the reliability and safety of the system, providing guarantee for the stable operation of the water pump.
[0022] At the same time, in terms of structural design, the present solution can drive the clamp arm 10 to expand outward by operating the handle 18 to press down the column 14 and the triangular seat 16, thereby forming a preliminary clamp on the water pipe 8. When the water pipe 8 is successfully connected, the handle 18 is released, and the spring 20 will exert its elastic potential energy to push the column 14 and the triangular seat 16 upward, thereby making the side clamping roller 12 and the lower clamping roller 15 fit tightly at the connection between the water pipe 8 and the water pump outlet pipe. This design cleverly utilizes the buffering and compensation capabilities of the spring, effectively alleviating the stress and displacement problems that may be caused by thermal expansion and contraction of the pipeline system, mechanical vibration during equipment operation, and other external factors.
[0023] The present solution also adds a supporting structure squeezed by a spring 20 at the connection of the water pump outlet pipe 8. This design can not only further enhance the stability of the entire circulating water system, but also compensate to a certain extent for the displacement that may be caused by factors such as installation error, pipe deformation or foundation settlement, thereby effectively avoiding water leakage during the use of the water pump and greatly improving the use quality and reliability of the water pump.
[0024] In summary, through a series of innovative designs and intelligent management strategies, this solution successfully achieved efficient and stable operation of circulating water pumps in various complex environments, providing strong technical support and guarantee for industrial production, agricultural irrigation, urban water supply and other fields.
