Technical Field
[0001] This utility model relates to the technical field of solar water heater insulation boxes, specifically a solar water heater insulation box with constant pressure and leak prevention. Background Technology
[0002] With the increasing scarcity of non-renewable energy sources on Earth, solar energy, as a clean resource, is increasingly entering people's lives. Among them, solar water heaters are one of the most widely used daily necessities that utilize solar energy. Solar water heaters are heating devices that convert solar energy into heat energy, heating water from low temperature to high temperature to meet people's hot water needs in daily life and production. Solar water heaters are classified into vacuum tube solar water heaters and flat plate solar water heaters according to their structure, with vacuum tube solar water heaters being the main type. Solar water heaters usually require an insulated tank to store the water.
[0003] According to patent publication number CN 209085068 U, a solar water heater with a constant pressure leak-proof insulation tank is disclosed. This device facilitates regular cleaning of dirt inside the insulation tank through the synergistic action of the cleaning component and the pressure regulating component. It can also prevent water leakage caused by damage to the heat absorption tube in the cold season in the north. The mounting base can adapt to the typhoon climate in the south and prevent damage to the equipment caused by strong winds. However, it is inconvenient to disassemble the screw cap, which makes it difficult to perform deep cleaning of the inside of the insulation tank manually. Consequently, it is difficult to remove the scale inside the insulation tank manually, which affects the subsequent use of the insulation tank.
[0004] To address this issue, we propose a solar water heater insulation box with constant pressure and leak prevention. Utility Model Content

[0028] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.
[0029] Example 1
[0030] like Figure 1-5 As shown, this utility model provides a technical solution: a solar water heater insulation box with constant pressure and leak prevention, including an insulation box body 1, an end cover 2 disposed on one side of the insulation box body 1, a pressure regulating box 4 connected to one side of the insulation box body 1, and a connecting component 3 disposed on one side of the insulation box body 1. The connecting component 3 includes a disassembly and assembly mechanism 31 disposed on one side of the insulation box body 1, a pressure regulating mechanism 32 disposed on one side of the insulation box body 1, and a sealing ring 311 fixedly connected to the inner side of the end cover 2. A positioning block 312 is fixedly connected to the inner side of the end cover 2, a snap-fit groove 313 is opened on one side of the positioning block 312, and a positioning groove 314 is opened at the end of the insulation box body 1. The outer wall of the box body 1 is provided with a sliding groove 315. A sliding rod 316 is fixedly connected to the inner wall of the sliding groove 315. A slider 317 is slidably connected to the outer wall of the sliding rod 316. A first spring 318 is fixedly connected to the inner wall of the sliding groove 315. A connecting rod 319 is fixedly connected to the outer side of the slider 317. A locking rod 3110 is movably connected to one end of the connecting rod 319. A pull rod is fixedly connected to the top of the locking rod 3110. A second spring 3111 is fixedly connected to the outer side of the connecting rod 319. A corrosion-resistant layer 3112 is provided inside the insulation box body 1. An insulation layer 3113 is fixedly connected to the inner side of the corrosion-resistant layer 3112. An anti-pressure layer 3114 is fixedly connected to the side of the insulation layer 3113 away from the anti-pressure layer 3114.
[0031] In this embodiment, the positioning block 312 is engaged with the positioning groove 314.
[0032] Furthermore, one end of the first spring 318 is fixedly connected to the slider 317, and the top end of the second spring 3111 is fixedly connected to the pull rod. Through the cooperation of the sealing ring 311, positioning block 312, snap-fit groove 313, positioning groove 314, sliding groove 315, sliding rod 316, slider 317, first spring 318, connecting rod 319, snap-fit rod 3110, and second spring 3111, it is convenient for manual disassembly of the end cover 2, thereby facilitating manual deep cleaning of the interior of the insulation box body 1. This can prevent excessive scale buildup inside the insulation box body 1, which would affect the normal use of the insulation box body 1. At the same time, through the cooperation of the corrosion-resistant layer 3112, insulation layer 3113, and pressure-resistant layer 3114, the insulation box body 1 can have good corrosion resistance and pressure resistance, thereby extending the service life of the insulation box body 1.
[0033] Furthermore, the inner wall of the positioning groove 314 is provided with a snap-fit hole, and the snap-fit rod 3110 is snapped into the snap-fit groove 313 through the snap-fit hole.
[0034] Furthermore, the side of the pressure-resistant layer 3114 away from the insulation layer 3113 is fixedly connected to the inner wall of the insulation box body 1.
[0035] When it is necessary to disassemble the end cap 2, simply hold the lever and pull the locking rod 3110 outward to separate the locking rod 3110 from the locking groove 313 and the locking hole. Then, under the action of the first spring 318, the slider 317 can move in the sliding groove 315 through the sliding rod 316. This allows the connecting rod 319, which is fixedly connected to the outside of the slider 317, to move the locking rod 3110 to a position away from the locking hole and the locking groove 313, freeing up the operator's hand. Then, repeat the above operation to separate the locking rod 3110 from the locking groove 313 in other positions. Then, the end cap 2 can be removed manually, which facilitates the deep cleaning of the inside of the insulation box body 1 and prevents excessive scale buildup inside the insulation box body 1, which would affect the normal use of the insulation box body 1.
[0036] Example 2
[0037] Based on Example 1, a preferred embodiment of the solar water heater insulation box with constant pressure and leak prevention provided by this utility model is as follows: Figures 1 to 5 As shown: The pressure regulating mechanism 32 includes an air pump 321 fixedly installed on one side of the pressure regulating box 4, a pressure sensor 322 fixedly installed on the inner wall of the pressure regulating box 4, a hollow column 323 fixedly installed on the inner wall of the pressure regulating box 4, a solid column 324 sleeved inside the hollow column 323, a third spring 325 fixedly connected to the inner wall of the pressure regulating box 4, a piston 326 fixedly connected to the outer end of the solid column 324, and a limit ring 327 fixedly connected to the inner wall of the pressure regulating box 4.
[0038] In this embodiment, one end of the third spring 325 is fixedly connected to the piston 326. The third spring 325 is sleeved on the outside of the hollow column 323 and the solid column 324. Through the cooperation of the air pump 321, pressure sensor 322, hollow column 323, solid column 324, third spring 325, piston 326 and limiting ring 327, pressure adjustment operation can be performed to prevent changes in the internal pressure of the heat preservation box body 1, which could lead to damage and leakage of the heat absorption tube.
[0039] Furthermore, the air pump 321 is connected to the pressure regulating box 4.
[0040] Furthermore, there are two limit rings 327, symmetrically distributed on both sides of the piston 326.
[0041] When the external temperature sensor detects that the temperature is too low to the freezing point, the pressure sensor 322 is activated and detects the water pressure in the insulation box body 1 and the air pressure in the pressure regulating box 4. When the detected values of water pressure and air pressure are too high, in order to prevent the heat absorption tube connected to the insulation box body 1 from breaking due to cold contraction and thermal expansion, the water pressure needs to be adjusted. When the air pump 321 is activated to charge or release air, the position of the pressure regulating piston 326 can be changed. When the water pressure is too high, the air pump 321 releases air and the external solenoid valve reduces the flow rate. When the water pressure is too low, the air pump 321 charges air and the external solenoid valve increases the flow rate to restore it.
[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
