Description

Technical Field

[0001] The present application relates to the field of circulating water pumps, and in particular to an energy-saving circulating water pump. Background Art

[0002] Energy-saving circulating water pumps are a new type of equipment developed by integrating modern technology with traditional water pumps. They aim to address the low energy efficiency issues of traditional water pumps, such as a significant drop in efficiency under suboptimal operating conditions and energy waste caused by a single control method. To address these issues, energy-saving circulating water pumps utilize a variety of advanced technologies, including high-efficiency motors, variable frequency drive technology, and intelligent control systems. For example, high-efficiency drive methods such as permanent magnet synchronous motors reduce mechanical losses; the frequency converter allows for flexible motor speed adjustment, enabling the pump to precisely deliver liquid according to actual demand; and the intelligent control system utilizes sensor data for real-time monitoring and optimizes pump operation through automated control strategies, further improving energy efficiency. Furthermore, computer-aided design (CAD) and computational fluid dynamics (CFD) analysis tools have been used to optimize the impeller and pump casing internal structure, reducing fluid resistance losses. With growing global environmental awareness and increasingly stringent emission standards for industrial equipment, energy-saving circulating water pumps not only help companies reduce operating costs but also become a key technology for meeting environmental regulations. Furthermore, rising energy prices and the growing awareness of sustainable development are further driving market demand for this type of energy-efficient equipment.

[0003] At present, the patent with announcement number CN210799337U discloses a high-efficiency and energy-saving circulating water pump, which includes a water pump body, a fixed pipe connected to the top of the water pump body, a water outlet pipe connected to the right side of the water pump body, a connecting pipe provided on the top of the fixed pipe, and a water inlet pipe connected to the top of the connecting pipe. The high-efficiency and energy-saving circulating water pump limits the connecting pipe by a limit groove to prevent it from shaking back and forth during use, and then rotates the threaded rod to drive the fixing block to move inward through the threaded rod so that it is inserted into the interior of the fixing groove, thereby fixing the connecting pipe through multiple fixing blocks and threaded rods to prevent it from detaching from the limit groove during use. When disassembling, the threaded rod is rotated to drive the fixing block to move inward and outward through the threaded rod to detach it from the interior of the fixing groove, and then the connecting pipe is taken out.

[0004] Regarding the above-mentioned related technologies, the inventors believe that the following defects exist: when the water pump operates for a long time, the internal temperature of the water pump body increases, and long-term high temperature is likely to affect the normal operation of the water pump, so it needs to be improved. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present application provides an energy-saving circulating water pump to solve the above problems.

[0006] An energy-saving circulating water pump includes a water pump body, which includes a base, a pump body mounted on the base, and a motor mounted on the pump body. The base is connected to a mounting plate below the motor. A receiving groove is provided on the vertical side wall of the mounting block. A mounting box is slidably connected in the receiving groove. A cooling fan for heat dissipation is installed in the mounting box. A fixing plate is connected to one side of the mounting box. The fixing plate is tightly attached to the outer side wall of the mounting block. A limiting member for limiting the movement of the fixing plate is installed on the mounting block.

[0007] By adopting the above technical solution, when the water pump operates for a long time, the installation box is removed from the receiving slot and the cooling fan is started. The wind force generated by the cooling fan dissipates heat from the motor, thereby ensuring that the water pump can operate normally.

[0008] Optionally, the limiting member includes a limiting arm hinged to the outer wall of the mounting block and a limiting block connected to the movable end of the limiting arm, a first limiting groove for the limiting block to be inserted into is provided on the fixed plate, a fixed magnet is connected to the limiting block, and a first metal block for the fixed magnet to be adsorbed is connected in the first limiting groove.

[0009] By adopting the above technical solution, the installation box is pushed completely into the receiving slot, and then the limit arm is rotated so that the limit block is stuck in the first limit slot. The fixed magnet on the limit block is adsorbed on the first metal block in the first limit slot, thereby preventing the installation box from accidentally sliding out of the receiving slot.

[0010] Optionally, a second limiting groove for the limiting block to be inserted into is formed on the outer side wall of the installation box, and a second metal block for being adsorbed by the fixed magnet is connected to the bottom wall of the second limiting groove.

[0011] By adopting the above technical solution, after the installation box is pulled out of the accommodating groove, the limit block on the limit arm is inserted into the second limit groove, and the second magnet on the limit block is adsorbed on the second metal block, thereby limiting the installation box from sliding freely.

[0012] Optionally, a connecting groove is provided on the upper end surface of the fixing plate, a windshield plate that slides up and down is installed in the connecting groove, and a fastening pad for pressing against the windshield plate is connected to the inner side wall of the connecting groove.

[0013] By adopting the above technical solution, the wind shield can guide the heat dissipation fan, so that the wind of the heat dissipation fan can be accurately directed to the motor on the pump body, thereby improving the heat dissipation efficiency of the motor.

[0014] Optionally, a connecting strip is vertically connected to the upper end of the wind shield, and the connecting strip abuts against the upper end surface of the fixing plate.

[0015] By adopting the above technical solution, the windshield can be quickly pulled up through the connecting strip, which is simple to operate and saves time and effort.

[0016] Optionally, the heat dissipation fan is connected to the inner bottom wall of the installation box by bolts.

[0017] By adopting the above technical solution, the heat dissipation fan can be removed from the installation box by unscrewing the bolts, saving time and effort.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. When the water pump operates for a long time, remove the installation box from the receiving slot and start the cooling fan. The wind force generated by the cooling fan will dissipate the heat of the motor, thereby ensuring the normal operation of the water pump.

[0020] 2. Push the installation box completely into the receiving slot, then rotate the limit arm so that the limit block is stuck in the first limit slot. The fixed magnet on the limit block is adsorbed on the first metal block in the first limit slot, thereby preventing the installation box from accidentally sliding out of the receiving slot.

[0021] 3. The wind shield can guide the cooling fan so that the wind from the cooling fan can be accurately directed to the motor on the pump body, thereby improving the heat dissipation efficiency of the motor. BRIEF DESCRIPTION OF THE DRAWINGS

The terms used in this specification are intended only to describe specific embodiments and are not intended to limit this application. The term "and / or" as used in this specification includes any and all combinations of one or more of the relevant listed items.

[0028] The embodiment of the present application discloses an energy-saving circulating water pump. Figure 1 and Figure 2 , including a water pump body 1, the water pump body 1 includes a base 2, a pump body 3 fixedly mounted on the base 2 and a motor 4 mounted on the pump body 3.

[0029] Reference Figure 1 and Figure 2 The base 2 is fixedly connected to a mounting block 5 below the motor 4. A receiving slot 51 is defined on the vertical sidewall of the mounting block 5. A mounting box 52 is slidably connected within the receiving slot 51. A cooling fan 53 for dissipating heat is removably connected to the mounting box 52 via bolts. A fixing plate 54 is fixedly connected to one side of the mounting box 52. The fixing plate 54 is in close contact with the outer wall of the mounting block 5. A stopper 6 is mounted on the mounting block 5 to restrict the movement of the fixing plate 54. When the water pump is operated for an extended period of time, the mounting box 52 is removed from the receiving slot 51 and the cooling fan 53 is activated. The wind generated by the cooling fan 53 dissipates heat from the motor 4, thereby ensuring normal operation of the water pump.

[0030] Reference Figure 1 and Figure 2 The limiting member 6 includes a limiting arm 61 hinged to the outer wall of the mounting block 5 and a limiting block 62 vertically fixedly connected to the movable end of the limiting arm 61. A first limiting groove 541 for the limiting block 62 to be inserted into is provided on the fixing plate 54. A fixed magnet 63 is fixedly connected to the limiting block 62. A first metal block 542 for the fixed magnet 63 to be adsorbed is fixedly connected in the first limiting groove 541. The first metal block 542 is an iron block. Push the entire mounting box 52 into the receiving groove 51, then rotate the limiting arm 61 so that the limiting block 62 is inserted into the first limiting groove 541. The fixed magnet 63 on the limiting block 62 is adsorbed on the first metal block 542 in the first limiting groove 541, thereby preventing the mounting box 52 from accidentally sliding out of the receiving groove 51.

[0031] Reference Figure 1 and Figure 2The outer wall of the mounting box 52 is provided with a second limiting groove 521 for the limiting block 62 to engage. A second metal block 522, which is an iron block, is fixedly connected to the bottom wall of the second limiting groove 521 for the fixed magnet 63 to attract. After the mounting box 52 is pulled out of the receiving slot 51, the limiting block 62 on the limiting arm 61 is inserted into the second limiting groove 521. The second magnet on the limiting block 62 is attracted to the second metal block 522, thereby preventing the mounting box 52 from sliding freely.

[0032] Reference Figure 1 and Figure 2 The upper end surface of the fixing plate 54 is provided with a connecting groove, within which a windshield 7 is mounted, which slides up and down. A fastening pad 8 made of silicone is fixedly attached to the inner sidewall of the connecting groove, which is used to press against the windshield 7. The windshield 7 guides the cooling fan 53 so that the air from the cooling fan 53 is accurately directed to the motor 4 on the pump body 3, thereby improving the heat dissipation efficiency of the motor 4. The fastening pad 8 presses against the windshield 7, creating a certain damping effect. When the windshield 7 is pulled upward, it can be stopped at any height.

[0033] Reference Figure 1 and Figure 2 The upper end of the windshield 7 is vertically fixedly connected with a connecting strip 9, which abuts against the upper end surface of the fixing plate 54. The windshield 7 can be quickly pulled up by the connecting strip 9, which is simple to operate and saves time and effort.

[0034] The implementation principle of an energy-saving circulating water pump in an embodiment of the present application is: when the water pump operates for a long time, the installation box 52 is removed from the receiving groove 51, and the heat dissipation fan 53 is started. The wind force generated by the heat dissipation fan 53 dissipates heat to the motor 4, thereby ensuring that the water pump can operate normally.

[0035] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
