Description

Technical Field

[0001] The utility model relates to the technical field of solar water heaters, in particular to a solar water heater with an automatic water stop device. Background Art

[0002] A solar water heater is a device that converts sunlight energy into heating, heating water from low temperature to high temperature to meet people's needs for hot water in life and production. Solar water heaters are divided into vacuum tube solar water heaters and flat plate solar water heaters according to their structural form, with vacuum tube solar water heaters being the main type. However, vacuum tube household solar water heaters are composed of related parts and accessories such as collector tubes, water storage tanks and brackets. The conversion of solar energy into thermal energy mainly relies on vacuum collector tubes. Vacuum collector tubes use the principle that hot water floats and cold water sinks to create microcirculation in the water and obtain the required hot water.

[0003] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: when filling the existing solar water heaters, most of them require manual observation to see whether the water inside the water collecting tank is full. After it is full, the water valve needs to be manually closed. If the user fails to close the water valve in time, the water in the water collecting tank overflows, thereby causing a waste of water resources. Therefore, we propose a solar water heater with an automatic water shut-off device to solve the above-mentioned problems. Utility Model Content

[0014] 1.

[0024] Through the water collecting box 1, the water injection pipe 2, the limit block 7, the positioning column 8, and the fixing block 13 can be installed respectively. Since the floating plate 9 is plugged into the outer surface of the floating plate 9, and the connecting rod 10 is fixedly installed on the inner wall of the floating plate 9, and the transmission rod 12 is hinged to the bottom of the connecting rod 10, and the middle part of the transmission rod 12 is hinged to the inside of the fixing block 13, the external water pipe is connected with the water injection pipe 2, and when the water inside the water collecting box 1 is filled, the floating plate 9 is moved along the positioning column 8 to fill the water collecting box 1. The column 8 floats up and drives the connecting rod 10 to rise. At the same time, the connecting rod 10 rotates around the hinge of the transmission rod 12 as the central axis, and the middle part of the connecting rod 10 rotates around the hinge of the fixed block 13 as the central axis, so that the transmission rod 12 is tilted. Under the action of the lever principle, the other end of the transmission rod 12 drives the plug 14 to compress the plugging pad 21, so that the plugging pad 21 contacts the top of the water injection pipe 2, thereby blocking the water collecting tank 1 and stopping water from entering the water collecting tank 1, thereby avoiding waste of water resources.

[0025] See also Figure 2 , Figure 4 The upper end of the connecting rod 10 is fixedly connected to the floating plate 9, and the bottom of the connecting rod 10 is hinged to one end of the top of the transmission rod 12, and the middle part of the transmission rod 12 is hinged to the fixed block 13.

[0026] The floating plate 9 and the transmission rod 12 can be supported by the connecting rod 10, so that when the water inside the water collecting tank 1 is filled, the floating plate 9 floats up along the positioning column 8 and drives the connecting rod 10 to rise, and the connecting rod 10 rotates around the hinge of the transmission rod 12 as the central axis, and at the same time, the middle part of the connecting rod 10 rotates around the hinge of the fixed block 13 as the central axis, thereby making the transmission rod 12 tilted. Under the action of the lever principle, the other end of the transmission rod 12 drives the plug 14 to compress the blocking pad 21, so that the blocking pad 21 contacts the top of the water injection pipe 2, thereby blocking the water collecting tank 1 and stopping water from entering the water collecting tank 1, thereby avoiding waste of water resources.

[0027] See also Figure 2 , Figure 3 Two extension rods 31 are fixedly connected to the bottom of the support frame 3, and a limiting groove 32 is opened in the middle of the support frame 3, and a positioning component 11 is installed in the middle of the support frame 3 and inside the limiting groove 32, and a fixing column 6 is sleeved inside the limiting groove 32, and an adjustment bracket 5 is fixedly connected to the lower end of the fixing column 6, and sockets 51 are opened on the left and right sides of the inside of the adjustment bracket 5, and the two extension rods 31 are inserted into the inside of the two sockets 51, and a plurality of adjustment holes 61 are equidistantly opened on the front of the fixing column 6, and the positioning component 11 is inserted into the inner wall of the adjustment hole 61.

[0028] The water collecting tank 1 can be supported by the support frame 3. Since two extension rods 31 are fixedly connected to the bottom of the support frame 3, a limiting groove 32 is provided in the middle of the support frame 3, and a positioning component 11 is installed in the middle of the support frame 3 and inside the limiting groove 32. The inside of the limiting groove 32 is sleeved with a fixing column 6, thereby stretching the positioning component 11 so that the positioning component 11 is disengaged from the inside of the adjusting hole 61. At this time, the positioning component 11 releases the limitation on the fixing column 6, and then pushes the fixing column 6 to drive the adjusting bracket 5 to move downward. The two extension rods 31 slide along the two sockets 51, so that the height of the support frame 3 is adjustable, thereby facilitating the adjustment of the angles of the water collecting tank 1 and the vacuum tube 4 at different installation positions.

[0029] See also Figure 3 , Figure 5 The positioning component 11 includes a mounting bracket 111, and the positioning component 11 is fixedly mounted on the front side of the support frame 3. At the same time, a through hole 112 is opened on the inner wall of the mounting bracket 111, and the through hole 112 is connected to the limiting groove 32. A latch rod 113 is inserted into the inner wall of the through hole 112.

[0030] The latch rod 113 and the spring 114 can be installed through the mounting bracket 111 and the through hole 112 in the positioning component 11. Since one end of the latch rod 113 is inserted into the inner wall of the adjusting hole 61, and the spring 114 is fixedly connected to the outer surface of the latch rod 113 and is located on the inner wall of the through hole 112, the latch rod 113 is stretched so that the latch rod 113 slides outward along the through hole 112. At this time, the spring 114 compresses the latch rod 113, and the latch rod 113 is separated from the inner wall of the adjusting hole 61, so that the positioning component 11 releases the limit on the fixed column 6, and at the same time pushes the fixed column 6 to drive the adjusting bracket 5 to move downward, and the two extension rods 31 slide along the two insertion holes 51, so that the height of the support frame 3 can be adjusted, thereby facilitating the angle adjustment of the water collecting tank 1 and the vacuum tube 4 at different installation positions.

[0031] During operation, the water injection pipe 2, the limit block 7, the positioning column 8, and the fixing block 13 can be installed respectively through the water collecting box 1. Since the floating plate 9 is plugged into the outer surface of the floating plate 9, and the connecting rod 10 is fixedly installed on the inner wall of the floating plate 9, and the transmission rod 12 is hinged to the bottom of the connecting rod 10, and the middle part of the transmission rod 12 is hinged to the inside of the fixing block 13, the external water pipe is connected with the water injection pipe 2, and when the water inside the water collecting box 1 is filled, the floating plate 9 is moved along the inner wall of the floating plate 9. The positioning column 8 floats up and drives the connecting rod 10 to rise. At the same time, the connecting rod 10 rotates around the hinge of the transmission rod 12 as the central axis, and the middle part of the connecting rod 10 rotates around the hinge of the fixed block 13 as the central axis, so that the transmission rod 12 is tilted. Under the action of the lever principle, the other end of the transmission rod 12 drives the plug 14 to compress the plugging pad 21, so that the plugging pad 21 contacts the top of the water injection pipe 2, thereby blocking the water collecting tank 1 and stopping water from entering the water collecting tank 1, thereby avoiding waste of water resources.

[0032] The floating plate 9 and the transmission rod 12 can be supported by the connecting rod 10, so that when the water inside the water collecting tank 1 is filled, the floating plate 9 floats up along the positioning column 8 and drives the connecting rod 10 to rise, and the connecting rod 10 rotates around the hinge of the transmission rod 12 as the central axis, and at the same time, the middle part of the connecting rod 10 rotates around the hinge of the fixed block 13 as the central axis, thereby making the transmission rod 12 tilted. Under the action of the lever principle, the other end of the transmission rod 12 drives the plug 14 to compress the blocking pad 21, so that the blocking pad 21 contacts the top of the water injection pipe 2, thereby blocking the water collecting tank 1 and stopping water from entering the water collecting tank 1, thereby avoiding waste of water resources.

[0033] The water collecting tank 1 can be supported by the support frame 3. Since two extension rods 31 are fixedly connected to the bottom of the support frame 3, a limiting groove 32 is provided in the middle of the support frame 3, and a positioning component 11 is installed in the middle of the support frame 3 and inside the limiting groove 32. The inside of the limiting groove 32 is sleeved with a fixing column 6, thereby stretching the positioning component 11 so that the positioning component 11 is disengaged from the inside of the adjusting hole 61. At this time, the positioning component 11 releases the limitation on the fixing column 6, and then pushes the fixing column 6 to drive the adjusting bracket 5 to move downward. The two extension rods 31 slide along the two sockets 51, so that the height of the support frame 3 is adjustable, thereby facilitating the adjustment of the water collecting tank 1 and the vacuum tube 4 at different installation positions.

[0034] The latch rod 113 and the spring 114 can be installed through the mounting bracket 111 and the through hole 112 in the positioning component 11. Since one end of the latch rod 113 is inserted into the inner wall of the adjusting hole 61, and the spring 114 is fixedly connected to the outer surface of the latch rod 113 and is located on the inner wall of the through hole 112, the latch rod 113 is stretched so that the latch rod 113 slides outward along the through hole 112. At this time, the spring 114 compresses the latch rod 113, and the latch rod 113 is separated from the inner wall of the adjusting hole 61, so that the positioning component 11 releases the limit on the fixed column 6, and at the same time pushes the fixed column 6 to drive the adjusting bracket 5 to move downward, and the two extension rods 31 slide along the two insertion holes 51, so that the height of the support frame 3 is adjustable, thereby facilitating the adjustment of the water collecting tank 1 and the vacuum tube 4 at different installation positions.

[0035] In summary, after the water filling pipe 2 of the device is filled with water into the water collecting tank 1, the floating plate 9 floats up along the positioning column 8, and the floating plate 9 drives the connecting rod 10 to rise, so that the transmission rod 12 is tilted. Under the action of the lever principle, the other end of the transmission rod 12 drives the plug 14 to compress the blocking pad 21, which contacts the top of the water filling pipe 2, thereby blocking the water collecting tank 1 and stopping water from entering the water collecting tank 1, thereby avoiding waste of water resources.
