DETAILED DESCRIPTION

[0022] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and embodiments, so that the implementation process of how the present application applies technical means to solve technical problems and achieve corresponding technical effects can be fully understood and implemented accordingly. The embodiments of the present application and the various features in the embodiments can be combined with each other without conflict, and the technical solutions formed are all within the protection scope of the present application.

[0023] It should be clear that the embodiments described below are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by technicians in the relevant field without making creative work are within the scope of protection of the present application. Example

[0024] like Figure 1-Figure 5 As shown, a building underground water pump circulation device includes a circulation speed control mechanism; the circulation speed control mechanism includes a driving assembly, a flow control blade 28, a guide wheel group 19, a sliding seat 26, a sliding rod 25 and an arc-shaped connecting rod 21; The guide wheel group 19 includes two gears meshing with each other. There are multiple guide wheel groups 19, and two adjacent gears are fixedly connected by an arc-shaped connecting rod 21. The flow control blade 28 is flipped and installed in the chamber enclosed by the arc-shaped connecting rod. The sliding seat 26 is provided with an arc-shaped slide groove 29, and one end of the sliding rod 25 is slidably set in the arc-shaped slide groove 29, and the other end is connected to the guide wheel group 19 by transmission. The driving component is connected to the guide wheel group 19 by transmission. Each guide wheel group 19 is equipped with a support block 22 and a rotating shaft. The rotating shaft is rotatably arranged in the middle of the gear. One end of the rotating shaft is connected to the support block 22 by rotation, and the other end is connected to the flow control blade 28 by rotation. The end of the sliding rod 25 facing away from the arc-shaped slide groove 29 is fixed to the support block 22.

[0025] The component connection relationship and working principle of the circulation speed control mechanism are as follows: When the guide wheel assembly 19 is driven to rotate, the end of the flow control blade 28 moving synchronously with it can be driven to flip. Figure 3 For example, when the guide wheel assembly 19 rotates counterclockwise, the end of the flow control blade 28 connected to it is in the lowest state, that is, the left side of the arc-shaped connecting rod 21 is at the lowest end, and its right side will tilt upward, and the connection between each flow control blade 28 will be in this state, and because the sliding rod 25 is slidably set in the arc-shaped slide groove 29, it will gather toward the guide wheel assembly 19, similar to the structure of a folding fan, so that the water inlet becomes larger to adapt to the state when the water pressure increases. The folded state is as follows Figure 6 shown. Example

[0026] This embodiment describes the driving component based on the embodiment 1: The driving assembly includes a slide rail rod 16, a main driving wheel 17 and a shaft; a transmission tooth segment 15 is provided on the slide rail rod 16, and the transmission tooth segment 15 and the main driving wheel 17 are meshed and driven, and the main driving wheel 17 rotates synchronously through the shaft and the gear.

[0027] Drive components such as Figure 3As shown, when the slide rail rod 16 moves up and down, the driving gear segment 15 on the slide rail rod 16 drives the main guide wheel 17 meshing with the main guide wheel 17 to rotate. Example

[0028] This embodiment describes the water pressure coordination control component based on Embodiment 1 and Embodiment 2: The water pressure cooperative control component includes a sliding column 20, a bearing seat 1, a water pressure sensing plate 2 and a support ring 13; the sliding column 20 is fixed to the upper end of the sliding seat 26, and the sliding block 8 is slidably sleeved on the sliding column 20; the inner side of the bearing seat 1 is fixed by a rod and the upper side end of the sliding column 20; one side of the water pressure sensing plate 2 is rotatably connected to the support ring 13, and the other end rotates synchronously with the outer side of the bearing seat 1.

[0029] The water pressure cooperative control component also includes a rotating seat 3, a connecting seat 4, an upper rotating rod 5, a lower rotating rod 7 and a sliding block 8; the rotating seat 3 is fixed to the outer side of the bearing seat 1; one end of the upper rotating rod 5 is fixed to the connecting seat 4, and the other end is vertically rotatably connected to the rotating seat 3; one end of the lower rotating rod 7 is fixed to the sliding block 8, and the other end is horizontally rotatably connected to the connecting seat 4.

[0030] The hydraulic pressure cooperative control assembly also includes a connecting rod 10, one end of which is fixed to the sliding block 8, and the other end is fixed to the slide rail rod 16. The hydraulic pressure cooperative control assembly also includes a spring 6 and an extension piece 9, one end of the spring 6 is fixed to the sliding block 8, and the other end is fixed to the extension piece 9, and the spring 6 is sleeved on the sliding column 20.

[0031] like Figure 3-5 As shown, the principles and advantages of the water pressure coordination control component are: Fully mechanical real-time feedback The water pressure sensor directly senses the impact of water flow, converts the pressure change into the displacement of the sliding block, and uses the connecting rod, rotating rod and other purely mechanical structures to drive the components to achieve instant adjustment of the flow control blades. No electronic sensors or complex control programs are required, the response speed is fast and the stability is high, which is especially suitable for underground humid environments.

[0032] Nonlinear pressure buffer design The combination of spring and extension piece provides adaptive buffering: when the water pressure suddenly increases, the spring compresses to absorb the impact energy and prevent the slider from instantaneous overload. The two work together to adapt to the drastic fluctuations in water pressure and protect the mechanical parts from impact damage.

[0033] Multi-dimensional motion transmission mechanism Through the vertical-horizontal linkage conversion of the upper and lower rotating rods and the connecting seat, the tilt angle change of the water pressure sensing plate is converted into the precise linear displacement of the slider, realizing the efficient conversion of three-dimensional force into two-dimensional mechanical action, ensuring the sensitivity and accuracy of pressure feedback. Example
