[0002] The secondary pump discharges from the air conditioning terminal equipment, receives water, and transports it to the supply and return water pipeline, passes through the secondary pump, and then returns to the air conditioning terminal equipment again. This part is mainly responsible for circulating water through the air conditioning system. The use of the secondary pump can make the entire system roughly have the function of outputting cold and heat according to actual needs.

[0003] The existing cold water secondary pump flow has the function of adaptive adjustment. When in use, the connecting line of the controller set on most cold water secondary pump flows will extend to the outside of the water pipe. Since most of the existing cold water secondary pump flows are not equipped with a mechanism to prevent the connecting line from bending and entanglement, when the connecting line is subjected to external force and the external force drives the connecting line to move in multiple directions, the connecting line may bend and entangle, which will cause the end of the connecting line close to the water pipe to be damaged, and then the service life of the connecting line will be reduced.

[0006] In the above-mentioned cold water secondary pump flow adaptive regulator, the movable plate one and the movable plate two can protect the connecting wire to prevent it from bending and entanglement when subjected to multiple reverse forces, thereby preventing the end of the connecting wire close to the water pipe from being damaged. At the same time, it is also convenient for personnel to store the redundant connecting wires.

[0007] As a further improvement of the present application, a pair of reinforcement blocks are fixedly connected to the lower end of the movable plate one, and a pair of reinforcement grooves movably plugged into the reinforcement blocks are formed at the upper end of the movable plate two.

[0008] As a further improvement of the present application, the outer ends of the movable plate 1 and the movable plate 2 are both fixedly connected with a first magnetic ring, and the inner wall of the circular groove is fixedly connected with a second magnetic ring.

[0023] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0024] The first implementation method:

[0025] Figure 1-7A flow adaptive regulator for a cold water secondary pump is shown, comprising a water pipe 1, the outer end of which is fixedly connected to a regulating motor 2. A person skilled in the art can select the best model of the regulating motor 2, such as model Y80M1-2. A circular plate 3 is provided inside the water pipe 1, the output end of the regulating motor 2 moves from the outside to the inside through the water pipe 1 and is fixedly connected to the circular plate 3. A flow sensor is fixedly connected to the inner wall of the water pipe 1, which is not shown in the figure. The flow sensor is a capacitive flow sensor. The outer end of the flow sensor is fixedly connected to one end of a connecting wire 4, and the end of the connecting wire 4 away from the flow sensor moves from the inside to the outside through the inner wall of the water pipe 1 and is fixedly connected to a controller 15. The controller 15 is a PCL controller. The upper end of the controller 15 is fixedly connected to the lower end of the regulating motor 2. A circular groove 5 is provided at the outer end of the water pipe 1. A circular hole is provided on the inner wall of the circular groove 5, and a sealing tube 6 is fixedly connected to the inner wall of the circular hole. The inner wall of the sealing tube 6 is slidably connected to the outer end of the connecting line 4. A movable plate 17 and a movable plate 2 13 are movably connected inside the circular groove 5. The outer end of the movable plate 17 is fixedly connected to a fixed frame 10, and a winding tube 11 is fixedly connected to the inner wall of the fixed frame 10. A pair of reinforcement blocks 12 are fixedly connected to the lower end of the movable plate 17, and a pair of reinforcement grooves 14 movably connected to the reinforcement blocks 12 are provided at the upper end of the movable plate 2 13. The outer ends of the movable plates 17 and 13 are fixedly connected to the first magnetic ring 8, and the inner wall of the circular groove 5 is fixedly connected to the second magnetic ring 9. The outer end of the circular plate 3 is fixedly connected to the sealing ring 17. When the circular plate 3 is in a vertical state in the water pipe 1, the sealing ring 17 can be used to improve the sealing of the inner wall of the water pipe 1 to prevent water from passing through the circular plate 3.

[0026] This solution can be realized. When in use, a flow sensor (not shown in the figure) is used to detect the water flow, and then the detection information is transmitted to the controller 15. The controller 15 is used to start the regulating motor 2, so that the regulating motor 2 rotates, and then the circular plate 3 rotates in the water pipe 1, and then the angle of the circular plate 3 in the water pipe 1 is adjusted, so as to automatically adjust the water flow. When in use, the moving plate 1 7 and the moving plate 2 13 need to be sleeved on the connecting line 4, and at the same time, one end of the moving plate 1 7 and the moving plate 2 13 is inserted into the circular groove 5, and the moving plate 1 7 and the moving plate 2 are plugged in. 13, the first magnetic ring 8 will be attracted together with the second magnetic ring 9, thereby improving the stability of the moving plate 1 7 and the moving plate 2 13 in the circular groove 5, and the moving plate 1 7 and the moving plate 2 13 can be used to protect the connecting line 4 to prevent it from being bent and entangled when subjected to multiple reverse forces, thereby preventing the end of the connecting line 4 close to the water pipe 1 from being damaged, thereby improving the service life of the connecting line 4, and at the same time, personnel need to wind the excess connecting line 4 on the winding tube 11, which makes it convenient for personnel to store the excess connecting line 4.

[0027] The second implementation method:

[0028] Based on the first embodiment, this embodiment adds structures such as a limit frame 18 and a moving block 19, and the rest of the parts are consistent with the first embodiment.

[0029] Figure 5 and Figure 7 It is shown that the upper end of the fixed frame 10 is fixedly connected to the limiting frame 18, and a moving block 19 is provided below the limiting frame 18. A fixing rod 20 is inserted into the inside of the moving block 19, and a compression spring 16 is slidably sleeved on the outer end of the fixing rod 20. The lower end of the fixing rod 20 is fixedly connected to the upper end of the winding tube 11, and the upper end of the fixing rod 20 is fitted with the inner top wall of the limiting frame 18. The moving block 19 is overlapped on the upper end of the winding tube 11, and the upper end of the compression spring 16 is fixedly connected to the inner top wall of the limiting frame 18.

[0030] This solution can be achieved. Before winding the connecting wire 4 on the winding tube 11, the movable block 19 needs to be moved upward. At the same time, the movable block 19 will continue to apply force to the compression spring 16, so that the compression spring 16 continues to shrink on the fixed rod 20. After winding the connecting wire 4 on the winding tube 11, the external force applied to the movable block 19 needs to be removed. After the external force on the movable block 19 is removed, the compression spring 16 will push the movable block 19 to move downward and apply pressure to the wound connecting wire 4, thereby pressing the connecting wire 4 against the winding tube 11, thereby improving the stability of the connecting wire 4 when it is wound on the winding tube 11.

[0031] In view of current practical needs, the protection scope of the above-mentioned implementation mode adopted by this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
