[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Reference Figure 1 , Figure 2 and Figure 3 , the utility model provides an embodiment: an automatic dosing device for the pH value of urban recycled water, comprising a water storage tank 1 and a connecting belt 12, a bracket 6 is fixedly connected to the top of the water storage tank 1, a driving motor 15 is fixedly connected to the top of the bracket 6, the output end of the driving motor 15 passes through the bracket 6 and is fixedly connected to a driving pulley 14, a connecting frame 4 is fixedly connected to the left side of the bracket 6, a driven pulley 11 is rotatably connected to the bottom of the connecting frame 4, the driving pulley 14 is transmission-connected to the driven pulley 11 through the connecting belt 12, a metal gear 13 is fixedly connected to the bottom of the driving pulley 14, a sawtooth bar 16 is meshedly connected to the front side of the metal gear 13, a U-shaped tube 17 is installed on the front side of the sawtooth bar 16, a plurality of nozzles 18 are equidistantly connected to the bottom of the U-shaped tube 17, and a mixing mechanism 2 is installed on the left side of the water storage tank 1; a slide groove 5 is opened in the middle of the top wall of the water storage tank 1, and the sawtooth bar 16 is slidably connected to the slide groove 5; a connecting pipe 7 is connected to the top of the U-shaped tube 17, and a connecting valve 8 is installed on the outer side of the connecting pipe 7;

[0028] Specifically, the equipment needs to be connected to the discharge pipe first; this step connects the connecting pipe 7 to the discharge pipe through the connecting valve 8 to ensure that the pH value can be smoothly injected into the U-shaped tube 17; next, start the driving motor 15 to drive the active pulley 14 to rotate; the rotation of the active pulley 14 drives the connecting belt 12 to move, thereby causing the driven pulley 11 to rotate synchronously; this process is achieved through the rotation of the metal gear 13 and the meshing transmission with the sawtooth bar 16, further driving the sawtooth bar 16 to slide smoothly in the slide 5; this design carefully plans the moving trajectory of the sawtooth bar 16 to ensure its stability during the delivery process; during the movement of the sawtooth bar 16, the U-shaped tube 17 will move synchronously; in this way, the pH value can be effectively discharged through the nozzle 18; this mobile delivery method not only expands the delivery range, but also improves the uniformity of delivery.

[0029] Reference Figure 2 and Figure 3 The mixing mechanism 2 includes a connecting rod 201, the top of which is fixedly connected to the bottom of the driven pulley 11, the end of which is fixedly connected to a driving bevel gear 202, the right side of the connecting frame 4 is rotatably connected to a driven bevel gear 203, the driven bevel gear 203 is meshed with the driving bevel gear 202, the right end of the driven bevel gear 203 is fixedly connected to a fixing rod 204, the right end of the fixing rod 204 penetrates the water storage tank 1 and is fixedly connected to a mixing blade 205;

[0030] Specifically, the rotation of the driven pulley 11 plays a vital role; it not only drives the connecting rod 201 to rotate, but also drives the active bevel gear 202 to rotate synchronously through the rotation of the connecting rod 201; this process seems simple, but it contains precise mechanical principles; the rotation of the driven pulley 11 and the connecting rod 201 is linked, which further drives the synchronous rotation of the active bevel gear 202; this is because the connecting rod 201 transmits the rotation torque of the driven pulley 11 through the change of its shape and position during the rotation process, so that the active bevel gear 202 can rotate; and the rotation of the active bevel gear 202 The driving bevel gear 202 meshes with the driven bevel gear 203 when it rotates; this process is a typical example of mechanical energy transmission, which utilizes the meshing principle of bevel gears to transmit the rotational force of the driving bevel gear 202 to the driven bevel gear 203; the synchronous rotation of the driven bevel gear 203, the fixed rod 204 and the mixing blade 205 is the core part of the entire mechanical equipment; during the rotation process, they not only drive the overall movement of the equipment, but also realize the mixing of urban recycled water and pH value through the rotation of the mixing blade 205; this mixing method greatly improves the dissolution efficiency of pH value, which brings great convenience to subsequent use.

[0031] Reference Figure 1A sealing ring 3 is installed on the outer wall of the fixing rod 204; a sensor 10 is installed on the front side of the water storage tank 1; and a drain pipe 9 is connected to the front side of the water storage tank 1;

[0032] Specifically, the sealing ring 3 is used to prevent water leakage, the pH value of the water source is detected by the sensor 10, and the water source is discharged through the drain pipe 9.

[0033] Working principle: When it is necessary to add pH value to urban recycled water, the connecting pipe 7 is connected to the discharge pipe through the connecting valve 8, so that the pH value is injected into the U-shaped tube 17, and the driving motor 15 is turned on to drive the driving pulley 14 to rotate. The rotation of the driving pulley 14 is linked to the driven pulley 11 through the connecting belt 12 to rotate synchronously, and the rotation of the driving pulley 14 is also used to rotate the metal gear 13, and the rotation of the metal gear 13 is meshed with the sawtooth bar 16 to drive the sawtooth bar 16 to slide in the slide 5, and the movement trajectory of the sawtooth bar 16 is planned. The U-shaped tube 17 moves synchronously through the movement of the sawtooth bar 16, and the driving motor 15 is turned on. The nozzle 18 is started to discharge the pH value. The mobile delivery increases the range and uniformity of the pH value delivery, which can meet the subsequent use requirements. The connecting rod 201 is rotated while the driven pulley 11 rotates. The rotation of the connecting rod 201 causes the active bevel gear 202 to rotate synchronously. The rotation of the active bevel gear 202 is meshed with the driven bevel gear 203, thereby driving the driven bevel gear 203, the fixed rod 204 and the mixing blade 205 to rotate synchronously. The urban recycled water and the pH value are mixed together through the rotation of the mixing blade 205, which increases the dissolution efficiency of the pH value and brings convenience for subsequent use.
