[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 1-3 A solar heat pump heating device in this embodiment includes a collector 1 and a heat storage tank 2, an antifreeze heating component is installed on the heat storage tank 2, and a fixing component is installed on the heat storage tank 2.

[0022] The antifreeze heating assembly includes a connecting pipe 3 arranged between the collector 1 and the heat storage tank 2, two annular blocks 4 are fixedly installed on the outside of the heat storage tank 2, and the first insulation shell 5 and the second insulation shell 6 are slidably connected on the opposite sides of the two groups of annular blocks 4, and two heating plates 7 are arranged inside the first insulation shell 5 and the second insulation shell 6.

[0023] The outer sides of the first insulation shell 5 and the second insulation shell 6 are fixedly installed with connecting blocks 8, and the number of connecting blocks 8 is eight. The first bolts 9 are inserted into the inside of the two connecting blocks 8. Through holes are opened inside the two connecting blocks 8. The first bolts 9 are inserted into the connecting blocks 8 through the through holes, so as to facilitate the fixed installation connection of the first insulation shell 5 and the second insulation shell 6. One end of the first bolt 9 is threadedly connected with a nut 10.

[0024] It should be noted that the solar heat pump heating device, by installing an antifreeze heating component, reduces the drop in the temperature of hot water in the heat storage tank 2 on rainy days and in winter when the sunshine time is short, which is beneficial to improving the practicality of the device and facilitating meeting usage needs.

[0025] Specifically, when the solar heat pump heating device is in use, the computer controller automatically opens the cold water solenoid valve, and tap water enters the bottom of the collector 1. At the same time, the hot water at the top of the collector 1 that reaches the set temperature is pushed into the heat storage tank 2. The first insulation shell 5 and the second insulation shell 6 are fixedly limited to the outside of the heat storage tank 2 by the first bolts 9 and nuts 10. On rainy days and in winter when the sunshine time is short, the heating plates 7 in the first insulation shell 5 and the second insulation shell 6 are started to insulate and heat the hot water in the heat storage tank 2, thereby reducing the temperature drop of the hot water in the heat storage tank 2 and improving the practicality of the device.

[0026] The fixed component includes moving blocks 11 fixedly installed on the top and bottom of the first insulation shell 5 and the second insulation shell 6. The number of moving blocks 11 is several, and a slide groove is opened on the opposite side of the two annular blocks 4. The moving blocks 11 are slidably connected to the annular blocks 4 through the slide groove, which facilitates the first insulation shell 5 and the second insulation shell 6 to be moved out from between the two annular blocks 4 and release the connection with the heat storage box 2.

[0027] The two groups of moving blocks 11 are threadedly connected on one side opposite to each other with a second bolt 12, and the two annular blocks 4 are provided with extension holes inside, and the two groups of moving blocks 11 are provided with a second threaded hole on one side opposite to each other. The second bolt 12 is threadedly connected to the moving blocks 11 through the extension hole and the second threaded hole, so as to further fix and limit the first insulation shell 5 and the second insulation shell 6.

[0028] A water level monitor 13 is fixedly installed on one side of the inner wall of the heat storage tank 2 to monitor the water level in the heat storage tank 2 at all times. A mounting pipe 14 is fixedly installed on one side of the heat storage tank 2, and a heat pump unit 15 is fixedly installed on one side of the heat storage tank 2.

[0029] It should be noted that the solar heat pump heating device is installed with a fixed component, which facilitates the rapid installation and disassembly of the insulation shell and the heat storage box 2, thereby improving the flexibility of the device.

[0030] Specifically, the solar heat pump heating device releases the threaded connection between the first bolt 9 and the nut 10, pulls the first bolt 9 out of the connecting block 8, and then releases the threaded connection between the second bolt 12 and the moving block 11, and moves the first insulation shell 5 and the second insulation shell 6 out from between the two annular blocks 4, so as to facilitate the inspection and replacement of the heating plate 7, thereby improving the flexibility of the device.

[0031] The working principle of the above embodiment is:

[0032] (1) When the solar heat pump heating device is in use, the computer controller automatically opens the cold water solenoid valve, and tap water enters the bottom of the collector 1. At the same time, the hot water at the top of the collector 1 that has reached the set temperature is pushed into the heat storage tank 2. The first insulation shell 5 and the second insulation shell 6 are fixed and limited to the outside of the heat storage tank 2 by the first bolts 9 and nuts 10. On rainy days and in winter when the sunshine time is short, the heating plates 7 in the first insulation shell 5 and the second insulation shell 6 are started to heat and insulate the hot water in the heat storage tank 2, thereby reducing the temperature drop of the hot water in the heat storage tank 2 and improving the practicality of the device.

[0033] (2) The solar heat pump heating device releases the threaded connection between the first bolt 9 and the nut 10, pulls the first bolt 9 out of the connecting block 8, and then releases the threaded connection between the second bolt 12 and the moving block 11, and moves the first insulation shell 5 and the second insulation shell 6 out from between the two annular blocks 4, so as to facilitate the inspection and replacement of the heating plate 7, thereby improving the flexibility of the device.
