Description

Technical Field

[0001] The utility model relates to the technical field of hot water tanks, and particularly relates to a solar hot water tank. Background Art

[0002] A solar thermal insulation water tank refers to a device used in solar central hot water or solar heating projects to collect and store the hot water generated by a collector. Generally, it consists of an inner tank, a thermal insulation layer, and an outer shell. 1. Inner tank: Usually welded with sus304 stainless steel, it has high corrosion resistance and anti-pollution properties. 2. Thermal insulation layer: It is divided into several types: rock wool, rubber and plastic sponge, polyurethane foam, etc. The polyurethane foam has the best effect. 3. Outer shell: Since the outer shell mainly plays the role of protecting the thermal insulation layer and being aesthetically pleasing, it is generally made of a relatively thin stainless steel plate. In order to reduce costs, it is often made of color plates, and attention should be paid to anti-corrosion. Currently, during the practical use of solar water heaters, the inner tank is generally corroded, etc., and the inner tank needs to be replaced. However, the current inner tanks all have the problems of being unable to be replaced or difficult to replace, resulting in a reduction in the service life of solar water heaters.

Docking seats 4 are installed at both the upper and lower ends of the center of the outer side of the first housing 1. Mounting seats 5 are installed at both the upper and lower ends of the center of the outer side of the second housing 2. One side of the mounting seat 5 is in contact with one side of the docking seat 4. The docking seat 4 and the mounting seat 5 are snap-connected through a combined connection mechanism. The combined connection mechanism includes a turning component and a pressing component. The pressing component is used to snap-connect the docking seat 4 on the first housing 1 and the mounting seat 5 on the second housing 2. The turning component is used to unlock the position locking between the docking seat 4 and the mounting seat 5. When in use, the docking seat 4 on the first housing 1 and the mounting seat 5 on the second housing 2 can be snap-connected through the pressing component, and the turning component unlocks the position locking between the docking seat 4 and the mounting seat 5. The structure is simple and the operation is convenient. The staff only needs to squeeze and twist to complete the assembly and separation of the housing, further improving the efficiency of the staff for disassembly, replacement and installation.

[0024] In this embodiment, as Figure 1 , Figure 2 and Figure 3 shown, the pressing component includes an operating rod 6 rotatably connected inside the docking seat 4. A retraction groove is formed on the surface of the docking seat 4 that is in contact with the mounting seat 5. A positioning block 7 is installed at one end of the operating rod 6 extending into the inner side of the retraction groove. Clamping blocks 8 are installed at both ends of the positioning block 7. A docking groove 9 corresponding to the retraction groove is formed on one side of the mounting seat 5. The docking groove 9 is a circular groove. First, cover the first housing 1 and the second housing 2 outside the inner tank 3. The two sealing strips 22 increase the sealing performance at the joint. After the docking seat 4 and the mounting seat 5 are in contact, hold the pull ring 17 and drive the operating rod 6 to move, so that the pressing plate 16 stretches the two third springs, and the clamping blocks 8 and the positioning block 7 slide into the inner side of the installation groove along the docking groove 9.

[0025] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, a mounting groove is provided on one side of the docking groove 9 inside the mounting seat 5, and abutment grooves are provided on both sides of the inner wall of the mounting groove inside the mounting seat 5, and an abutment plate 10 is slidably connected to the inner side of the abutment groove, and two groups of first springs 11 are arranged and installed between one side of the abutment plate 10 and the inner wall of the abutment groove, and the opposite ends of the abutment plate 10 and the clamping block 8 are provided with inclined surfaces 12 that fit each other, and two groups of second springs 13 are arranged and installed on one side of the inner wall of the mounting groove, and a mounting plate 14 is installed on the other end of the second spring 13, and a movable plate 15 is rotatably connected inside the mounting plate 14, and a positioning groove is provided on one side of the movable plate 15, and the positioning groove and the positioning groove are connected. The positioning block 7 is a snap-fit ​​connection, and a slot is provided on the other side of the abutment plate 10, which is snap-fitted with the protruding end of the blocking block 8. Then, the blocking block 8 and the inclined surface 12 on the abutment plate 10 are in contact and extruded, forcing the abutment plate 10 to compress the two groups of first springs 11 to retract. After the positioning block 7 is snap-fitted with the positioning slot, it also compresses the mounting plate 14 to compress the two groups of second springs 13 to retract. After the blocking block 8 and the abutment plate 10 are misaligned, the abutment plate 10 is ejected by the first spring 11, and then the pull ring 17 is released, and the second spring 13 drives the mounting plate 14 to reset. The blocking block 8 moves upward accordingly, and the protruding end is snapped into the inner side of the slot to complete the crimping fixation.

[0026] In this embodiment, if Figure 1 , Figure 2 and Figure 3 As shown, the buckle and rotation assembly includes an extrusion groove opened inside the mounting seat 5 and located on the outside of the operating rod 6, an extrusion plate 16 is slidably connected to the inside of the extrusion groove, the extrusion plate 16 and the operating rod 6 are rotatably connected, two groups of third springs are arranged and installed between one side of the extrusion plate 16 and the inner wall of the extrusion groove, an extension groove is opened on the other side of the mounting seat 5, and the end of the operating rod 6 extending to the inside of the extension groove is rotatably connected with a pull ring 17. Furthermore, when separation and disassembly are required, it is only necessary to buckle the pull ring 17 and squeeze the mounting disk 14 again to allow the block 8 to detach from the inside of the slot, and then twist the pull ring 17 to cooperate with the positioning block 7 and the positioning groove to drive the movable disk 15 to rotate. After the block 8 is rotated to the longitudinal direction, it can be pulled out from the end of the docking groove 9, and the third spring drives the extrusion plate 16 and the operating rod 6 to move back, so that the block 8 is retracted into the inside of the retraction groove, and then the first shell 1 and the second shell 2 can be separated.

[0027] In this embodiment, if Figure 1 , Figure 2 and Figure 3As shown, a sliding groove is provided on the side of the mounting seat 5 away from the docking seat 4, and a sliding plate 18 is slidably connected to the inner side of the sliding groove, a buckling groove is provided on one side of the sliding plate 18, and limiting grooves 19 are provided on both sides of the sliding plate 18.

[0028] The implementation principle of a solar water heater in the embodiment of the present application is as follows: the first shell 1 and the second shell 2 are covered on the outside of the inner tank 3, and the two sets of sealing strips 22 increase the sealing of the joint. After the docking seat 4 and the mounting seat 5 are fitted, the pull ring 17 is buckled to drive the operating rod 6 to move, and the extrusion plate 16 stretches the two sets of third springs, and the clamping block 8 and the positioning block 7 slide into the inner side of the mounting groove along the docking groove. The clamping block 8 and the inclined surface 12 on the abutment plate 10 are in contact and extruded, forcing the abutment plate 10 to compress the two sets of first springs 11 to retract. After the positioning block 7 is engaged with the positioning groove, it also compresses the mounting plate 14 to compress the two sets of second springs 13 to retract. Until the clamping block 8 and the abutment plate 10 are misaligned, the abutment plate 10 is ejected by the first spring 11, and then the pull ring 17 and the second spring are released. The spring 13 drives the mounting disk 14 to reset, and the card block 8 moves upward accordingly, and the protruding end is inserted into the inner side of the card slot to complete the crimping fixation. When separation and disassembly are required, it is only necessary to buckle the pull ring 17 and squeeze the mounting disk 14 again to allow the card block 8 to be separated from the inner side of the card slot, and then twist the pull ring 17 to cooperate with the positioning block 7 and the positioning slot to drive the movable disk 15 to rotate. After the card block 8 is rotated to the longitudinal direction, it can be pulled out from the end of the docking slot 9. The third spring drives the extrusion plate 16 and the operating rod 6 to move back, so that the card block 8 is retracted into the inner side of the retraction groove, and then the first shell 1 and the second shell 2 can be separated. When the assembly is completed, the drag groove 20 can be buckled to cooperate with the limit block and the limit groove 19 to drive the sliding plate 18 to move, so that the magnetic block 21 and the iron block are adsorbed, and the pull ring 17 is covered to avoid accidental touch.
