[0002] In the process of industrial production and manufacturing, water needs to be injected into various materials in order to mix or dilute the materials. However, due to the large number of industrial materials and the different proportions of water required to be injected into different materials, when water is injected into various materials through water pumps, multiple sets of water pumps need to be set up to ensure that the water pumps can inject multiple streams of water into various materials in specific proportions. Obviously, this will increase the cost of equipment, and there are many inconveniences for staff when controlling and adjusting multiple sets of water pumps. For this reason, we propose an antifreeze type diversion water pump. Utility Model Content

[0020] 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 the embodiments. Based on the embodiments in 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.

[0021] See also Figure 1-4 The utility model provides a technical solution: an antifreeze type shunt water pump, comprising a base 1, a pump casing 11 is fixed on the upper end surface of the base 1, an impeller 13 is rotatably installed in the pump casing 11, a motor box 16 is fixedly connected to the lower end of the impeller 13 through an output shaft in the base 1, a plurality of mutually matching shunt pipes 12 are fixedly arranged at equal intervals on the periphery of the pump casing 11, a sealing sleeve 2 is fixedly installed in the shunt pipe 12, a sealing pin 21 plugged with the sealing sleeve 2 is slidably installed in the shunt pipe 12, a connecting pipe 3 is plugged into the outer end of the shunt pipe 12, a sealing plate 14 is plugged into the upper end surface of the pump casing 11, and a water injection pipe 15 matching the impeller 13 is fixed in the middle of the upper end surface of the sealing plate 14.

[0022] Working principle: When in use, according to the number of water diversions, a corresponding number of connecting pipes 3 are installed on the outer ends of each diversion pipe 12 on the periphery of the pump casing 11, and the position of the sealing pin 21 is adjusted in the corresponding diversion pipe 12, so that the relative position of the sealing pin 21 and the sealing sleeve 2 is adjusted, and the relative position of the two is adjusted, and the flow rate of water in the diversion pipe 12 can be controlled. The motor inside the motor box 16 is started, and the impeller 13 can be driven to rotate in the pump casing 11 through the output shaft. The external water can be introduced into the pump casing 11 through the water injection pipe 15, and the centrifugal force generated by the rotation of the impeller 13 can guide the water into each diversion pipe 12, and the water can be discharged in conjunction with the connecting pipe 3. A heating plate is fixed inside the pump casing 11, and the water can be heated by the heating plate to prevent the water from freezing in the pump casing 11, which can ensure the water circulation and avoid damage to the impeller 13.

[0023] Specifically, the upper ends of the sealing sleeve 2 and the sealing pin 21 are respectively provided with a first water guiding cavity 22 and a second water guiding cavity 23 that match each other. The upper end of the first water guiding cavity 22 is communicated with the outer side of the inner cavity of the shunt tube 12, and the inner end surface of the second water guiding cavity 23 is communicated with the inner side of the inner cavity of the shunt tube 12. The shunt tube 12 is provided with matching limiting sliding cavities 25 on the upper and lower sides, and the upper and lower ends of the sealing pin 21 are fixed with limiting sliding rods 24 that are plugged into the limiting sliding cavity 25. A rotating sleeve 26 is rotatably installed on the outer periphery of the shunt tube 12, and the inner end surface of the rotating sleeve 26 is provided with a limiting thread groove 27 that matches the outer end thread of the limiting sliding rod 24.

[0024] When adjusting the opening state and opening degree of the sealing sleeve 2 and the sealing pin 21, the rotating sleeve 26 is rotated on the periphery of the shunt pipe 12, and the movement direction of the limiting slide bar 24 can be limited by the sliding cooperation between the limiting slide cavity 25 and the limiting slide bar 24, so that the rotating rotating sleeve 26 can drive the sealing pin 21 to move back and forth in the sealing sleeve 2 through the thread cooperation between the limiting thread groove 27 and the limiting slide bar 24. When the first water guiding cavity 22 and the second water guiding cavity 23 are completely misaligned, the shunt pipe 12 can be sealed. When the two are partially overlapped, the shunt pipe 12 can be opened. The water flow rate in the shunt pipe 12 can be controlled by the overlap degree of the two, wherein the shunt pipe 12 and the rotating sleeve 26, and the sealing sleeve 2 and the sealing pin 21 are sealed and fitted with each other.

[0025] It is worth noting that a positioning tooth groove 31 is provided on the inner end surface of the connecting pipe 3 , a positioning tooth ring 32 which is plugged into the positioning tooth groove 31 is fixed to the outer end of the shunt pipe 12 , and a threaded sleeve 33 which is threadedly matched with the connecting pipe 3 is rotatably installed on the outer periphery of the shunt pipe 12 .

[0026] When connecting a corresponding number of connecting tubes 3 with the shunt tube 12, the connecting tube 3 can be installed on the outer end of the shunt tube 12 by plugging and fitting between the positioning tooth groove 31 and the positioning tooth ring 32. When the threaded sleeve 33 contacts the connecting tube 3, the threaded sleeve 33 is rotated. Through the threaded fit between the threaded sleeve 33 and the outer periphery of the connecting tube 3, the connecting tube 3 can be driven to move inward and can be positioned, wherein the connecting tube 3, the threaded sleeve 33 and the positioning tooth ring 32 are all sealed and fitted with each other.
