Description

Technical Field

[0001] The utility model relates to the field of intelligent pumps, in particular to an intelligent pump which is convenient for heat dissipation. Background Art

[0002] An intelligent pump is a pump that integrates advanced technology and control systems. It can automatically adjust flow, pressure and operating status according to demand. Compared with traditional pumps, intelligent pumps generally have higher flexibility, efficiency and automation. Variable frequency speed regulation pumps are one type of such intelligent pumps.

[0003] The power output of the variable frequency speed regulating pump is completed by the variable frequency motor, and its control end realizes variable frequency output control through the intelligent control system. During the continuous output process of the variable frequency motor, heat is generated. The traditional motor heat dissipation method uses heat dissipation fins to realize physical transmission heat conduction. Such a structural setting can meet the heat dissipation of the motor output in a short time. However, as the driving motor of the pump body, it will be in the starting state for a long time. If only the fin heat dissipation form of the machine body is used, the heat accumulated at the fins will increase, and the heat dissipation efficiency of the fins will become lower and lower, thereby affecting the continuous use of the variable frequency motor. Therefore, an intelligent pump that is easy to dissipate heat is proposed. Utility Model Content

[0028] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0029] The utility model provides Figure 1-7 The intelligent pump for heat dissipation shown includes a variable frequency motor 1, a transmission rod 102 is provided at the output end of the variable frequency motor 1, and further includes:

[0030] The impeller box 3 is connected to the end of the transmission rod 102 away from the variable frequency motor 1. A coupling 2 is provided between the transmission rod 102 and the impeller box 3. The coupling 2 is used to connect the impeller in the impeller box 3 and the transmission rod 102;

[0031] It should be noted that, in this solution, a pump body structure is composed of a variable frequency motor 1, a coupling 2 and an impeller box 3. First, the output end of the variable frequency motor 1 is connected to the impeller box 3 through the coupling 2. In this way, under the output drive of the variable frequency motor 1, the impeller in the impeller box 3 rotates to pump liquid. In the setting of this solution, an intelligently controlled variable frequency motor 1 is adopted, and its rotation speed is controlled by a controller to drive the impeller in the impeller box 3 to rotate at different speeds, thereby adjusting the liquid pumping speed.

[0032] The containing mechanism is arranged at the bottom end of the variable frequency motor 1 and the impeller box 3, and is used to support and install the pump body;

[0033] Specifically, a water inlet 301 is provided at one end of the impeller box 3 away from the coupling 2, a water outlet 302 is provided at the top of the impeller box 3, and a fixing plate 303 is provided at the bottom end of the impeller box 3. The fixing plate 303 is used to connect the containing mechanism, which includes a containing frame 4, and a groove is provided on the side of the containing frame 4.

[0034] The cooling mechanism is arranged on the outer wall of the variable frequency motor 1. The cooling mechanism includes a cooling water pipe 5. Flange joints 501 are provided at both ends of the cooling water pipe 5. The cooling water pipe 5 is coiled and sleeved on the outer wall of the variable frequency motor 1. The outer wall of the cooling water pipe 5 is provided with a connector for connecting to the variable frequency motor 1.

[0035] It should be noted that the cooling water pipe 5 can be conveniently connected to the cooling water supply end through the setting of the flange joint 501. In the actual operation process, if the pump body sucks liquid at room temperature or below room temperature, one of the flange joints 501 of the cooling water pipe 5 can also be connected to the water outlet 302 of the impeller box 3, so that the sucked water can be used as cooling water.

[0036] Specifically, the outer wall of the variable frequency motor 1 is surrounded by heat dissipation fins 101 , the cooling water pipe 5 is sleeved on the heat dissipation fins 101 , and the connector is used to clamp the cooling water pipe 5 to fit the surface of the heat dissipation fins 101 .

[0037] Furthermore, the connecting piece includes:

[0038] N-shaped card plate 6, N-shaped card plate 6 is sleeved on the outer wall of cooling water pipe 5, and the bottom ends of both arms of N-shaped card plate 6 are provided with plug-in slots 601, and the plug-in slots 601 are used for clamping heat sink fins 101;

[0039] It should be noted that an arc-shaped groove is opened in the middle of the N-shaped card plate 6, and the diameter of the groove is the same as the diameter of the pipe wall of the cooling water pipe 5. This also enables the N-shaped card plate 6 to fit the outer wall of the cooling water pipe 5, and the opening width of the plug-in slot 601 needs to exceed the thickness of the heat dissipation fin 101, so that heat dissipation fins 101 of different thicknesses can be clamped, thereby facilitating the clamping between the N-shaped card plate 6 and the heat dissipation fin 101.

[0040] The locking screws 602 are connected to the bottom of the two arms of the N-shaped clamping plate 6 along the central symmetrical thread, and one end of the multiple locking screws 602 passes through the multiple plug-in slots 601 respectively.

[0041] Furthermore, an extrusion protrusion 603 is provided at one end of the locking screw 602 and located in the insertion slot 601 , and a control button block 604 is provided at the other end of the locking screw 602 .

[0042] It should be noted that after the N-shaped card plate 6 is clamped on the extra wall of the heat sink 101 using the plug-in slot 601, after ensuring that the N-shaped card plate 6 fits the cooling water pipe 5 on the heat sink 101, in order to stabilize the connection, the locking screw 602 is rotated by rotating the control button block 604. At this time, under the threaded fit, the locking screw 602 moves toward the direction close to the plug-in slot 601, and the extrusion protrusion 603 moves synchronously close to the plug-in slot 601. At this time, the extrusion protrusion 603 slowly fits against the heat sink 101 and is squeezed to fix the position of the N-shaped card plate 6, thereby completing the position setting of the cooling water pipe 5, and then after the cooling water is introduced, it can cooperate with the heat sink 101 to dissipate heat from the variable frequency motor 1.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
