Description

Technical Field

[0001] This invention relates to the field of water pump technology, specifically to an intelligent water pump for a constant pressure variable frequency secondary water supply system. Background Technology

[0002] Secondary water supply, as a key component of the urban water supply system, is mainly used to compensate for insufficient pressure in the municipal water supply network and ensure the normal water demand of areas such as high-rise residential buildings and commercial buildings. When supplying water, intelligent water pumps are usually required.

[0003] According to patent publication number CN 115388016 A, an intelligent water pump for a constant pressure variable frequency secondary water supply system can be controlled separately through a control box and its status can be displayed through LED beads. This allows the first motor and the second motor to be used alternately or together, thereby ensuring water pressure and saving energy when water consumption is low at night, and extending the service life of the intelligent water pump due to the alternating use. However, after installation, the device has poor shock resistance. The mechanical vibration of the pump body during operation will be transmitted to the connecting pipes through flanges and pipe interfaces. Long-term vibration can easily lead to problems such as cracking of pipe welds, loosening of joints, and failure of valve seals.

Detailed Implementation

[0016] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention will now be described with reference to the accompanying drawings.

[0017] Example 1 like Figure 1-6As shown, the present invention provides a technical solution: an intelligent water pump for a constant pressure variable frequency secondary water supply system, including a mounting base 1, an intelligent water pump body 2 fixedly mounted on the upper part of the mounting base 1, an outlet pipe 4 connected to the left side of the intelligent water pump body 2, an inlet pipe 5 connected to the right side of the intelligent water pump body 2, a filter box 6 located to the right of the inlet pipe 5, and a connecting assembly 3 located on one side of the mounting base 1. The connecting assembly 3 includes a shock-absorbing mechanism 31 located at the bottom of the mounting base 1, a filter mechanism 32 located on the upper part of the mounting base 1, a disassembly and assembly mechanism 33 located on the upper part of the filter box 6, and a control box mounted on the upper part of the mounting base 1. The shock-absorbing mechanism 31 includes a control box with a control box mounted on the upper part of the mounting base 1. The mounting base 1 has a positioning groove 311 at the bottom, a positioning block 312 is fitted inside the positioning groove 311, a slot 313 is opened on one side of the positioning block 312, a shock-absorbing plate 314 is fixedly connected to the bottom of the positioning block 312, a shock-absorbing and anti-slip pad is fixedly connected to the bottom of the shock-absorbing plate 314, a movable groove 315 is opened inside the mounting base 1, a movable block 316 is slidably connected to the inner wall of the movable groove 315, a sloped locking block 317 is fixedly connected to one side of the movable block 316, a connecting rod 318 is fixedly connected to the side of the movable block 316 away from the sloped locking block 317, a first spring 319 is fixedly connected to the inner wall of the movable groove 315, and a pull rod is fixedly connected to the outer end of the connecting rod 318 through the connecting block.

[0018] In this embodiment, the inclined plate 317 is movably connected to the movable groove 315 and the locking groove 313. One end of the first spring 319 is fixedly connected to the movable block 316. The outer end of the connecting rod 318 is movably connected to the movable groove 315. Through the cooperation of the positioning groove 311, positioning block 312, locking groove 313, shock absorber 314, movable groove 315, movable block 316, inclined plate 317, connecting rod 318, and first spring 319, after the mounting base 1 is installed, the shock absorber 314 and the shock-absorbing anti-slip pad can achieve a good shock absorption and anti-slip effect. This can prevent flanges, pipe interfaces, etc. from loosening or cracking due to long-term vibration, thereby extending the service life of the device. In addition, the shock absorber 314 is easy to disassemble manually, which makes it easy to replace the shock absorber 314 with large wear in a timely manner, thus facilitating subsequent use.

[0019] When the damping plate 314 needs to be disassembled, simply pull the connecting rod outward to move the connecting rod 318. This will cause the movable block 316, which is fixedly connected to the inner end of the connecting rod 318, to move the inclined plate 317 outward simultaneously. This allows the inclined plate 317 to separate from the slot 313, and then the positioning block 312 to separate from the positioning groove 311. The damping plate 314 can then be removed, facilitating timely replacement of the worn damping plate 314. This provides better vibration damping and anti-slip effects for the device, preventing flanges and pipe joints from loosening or cracking due to long-term vibration, thus extending the service life of the device. Furthermore, when the damping plate 314 needs to be disassembled... 4. During installation, simply manually engage the positioning block 312, which is fixedly connected to the upper part of the shock absorber 314, with the positioning groove 311. When the positioning block 312 enters the positioning groove 311, the inclined plate 317 can be pressed into the movable groove 315, and at this time the first spring 319 is compressed. Subsequently, after the positioning block 312 and the positioning groove 311 are fully engaged, the movable block 316 can drive the inclined plate 317 to move outward under the elastic force of the first spring 319, so that the inclined plate 317 can engage with the groove 313, thereby fixing the shock absorber 314 to the bottom of the mounting base 1. The installation operation is simple and convenient, increasing the applicability of the device.

[0020] Example 2 Based on Example 1, a preferred embodiment of the intelligent water pump for a constant pressure variable frequency secondary water supply system provided by the present invention is as follows: Figures 1 to 6 As shown: The filtration mechanism 32 includes a mounting bracket 321 fixedly installed inside the filter box 6. A rotating shaft 322 is rotatably connected inside the mounting bracket 321 via a bearing. A guide plate 323 is fixedly connected to the outer wall of the rotating shaft 322. A cleaning brush 324 is fixedly connected to the end of the rotating shaft 322 away from the guide plate 323. A filter plate 325 is fixedly installed inside the filter box 6. A collection pipe 326 is connected to the bottom of the filter box 6.

[0021] In this embodiment, the cleaning brush 324 contacts the filter plate 325, and connecting pipes are provided on both sides of the filter box 6. At the same time, the liquid inlet pipe 5 is connected to the connecting pipe through a flange. A valve is provided at the end of the collection pipe 326 away from the filter box 6. Through the cooperation of the mounting bracket 321, the rotating shaft 322, the guide plate 323, the cleaning brush 324, and the filter plate 325, the water source entering the intelligent water pump body 2 can be filtered. This can prevent impurities in the water from adhering to the intelligent water pump body 2 and affecting the subsequent use of the intelligent water pump body 2. When the water flows through the filter box 6, the surface of the filter plate 325 can be self-cleaned, which can prevent the filter holes of the filter plate 325 from being blocked and affecting the delivery of the water source.

[0022] When water passes through the filter box 6, the filter plate 325 filters the water, preventing impurities from adhering to the intelligent water pump body 2 and affecting its subsequent use. The flow of water causes the guide plate 323 to rotate the shaft 322, which in turn causes the cleaning brush 324, which is fixedly connected to one end of the shaft 322, to rotate synchronously, thus cleaning the surface of the filter plate 325. Impurities can then be collected in the collection pipe 326, further increasing the applicability of the device.

[0023] Example 3 Based on Example 1, a preferred embodiment of the intelligent water pump for a constant pressure variable frequency secondary water supply system provided by the present invention is as follows: Figures 1 to 6 As shown: The disassembly and assembly mechanism 33 includes an installation groove 331 inside the filter box 6. An installation frame 332 is inserted into the installation groove 331. A limit groove 333 is provided on the upper part of the installation frame 332. A sealing ring 334 is fixedly connected to the inner wall of the filter box 6 and is located at the gap between the installation frame 332 and the installation groove 331. A sliding groove 335 is provided on the upper part of the filter box 6. A sliding rod 336 is fixedly connected to the inner wall of the sliding groove 335. A slider 337 is slidably connected to the outer wall of the sliding rod 336. A second spring 338 is fixedly connected to the inner wall of the sliding groove 335. A limit rod 339 is fixedly connected to the upper part of the slider 337. A snap-fit ​​rod 3310 is movably connected to one end of the limit rod 339. A pull rod is fixedly connected to the top of the snap-fit ​​rod 3310. A third spring 3311 is fixedly connected to the upper part of the limit rod 339.

[0024] In this embodiment, the bottom of the limiting rod 339 is tightly fitted to the top of the mounting frame 332, and the filter plate 325 is fixedly installed inside the mounting frame 332. The snap-fit ​​rod 3310 is snapped into the limiting groove 333. Through the cooperation of the mounting groove 331, mounting frame 332, limiting groove 333, sealing ring 334, sliding groove 335, sliding rod 336, slider 337, second spring 338, limiting rod 339, snap-fit ​​rod 3310, and third spring 3311, it is convenient for manual disassembly of the mounting frame 332, thereby facilitating manual deep cleaning of the filter plate 325, resulting in better cleaning effect and further preventing the filter holes of the filter plate 325 from becoming clogged, which would affect subsequent water supply operations.

[0025] Furthermore, one end of the second spring 338 is fixedly connected to the slider 337, and the top end of the third spring 3311 is fixedly connected to the pull rod.

[0026] When the mounting frame 332 needs to be disassembled, simply pull the locking rod 3310 upwards manually to separate it from the limiting groove 333. Then, under the action of the second spring 338, the slider 337 slides in the sliding groove 335 via the sliding rod 336. This allows the limiting rod 339, which is fixedly connected to the upper part of the slider 337, to stay away from the upper part of the mounting frame 332, freeing up the operator's hands. The mounting frame 332 can then be removed upwards for deep cleaning of the sliding groove 335, further preventing the filter holes of the filter plate 325 from becoming clogged and affecting subsequent use.
