Description

Technical Field

[0001] The utility model belongs to the technical field of solar water heaters, and specifically relates to a water level indicating device for a solar water heater. Background Art

[0002] In modern society, solar water heaters have been widely used as a renewable energy device. However, there are some problems with traditional water level indicator devices for solar water heaters. Usually, these devices are set inside the water heater tank, which brings inconvenience to maintenance and installation, and requires more time and effort.

[0003] In addition, the water in the water heater is prone to scale during the heating process, and these scales will adhere to the inner wall of the water level indicator, resulting in inaccurate water level display. Due to the presence of scale, the water level may not be clearly seen when observed from the outside, which brings trouble to users.

[0004] In order to solve these problems, a solar water heater water level indicator is needed. The device should not only be easy to install and maintain, but also effectively remove scale, improve the accuracy of water level display, and facilitate user observation. Utility Model Content

[0005] The purpose of this utility model is to provide a water level indicator device for a solar water heater. The device should not only be easy to install and maintain, but also effectively remove scale, improve the accuracy of water level display, and facilitate user observation.

[0006] The technical solutions adopted in this utility are as follows:

[0007] A water level indicator device for a solar water heater comprises a water heater body, two symmetrical mounting plates are arranged outside the water heater body, a telescopic assembly is arranged on the top mounting plate, a first connecting rod is installed at the telescopic end of the telescopic assembly, a mounting groove is opened on the bottom mounting plate, and a water level indicator assembly is installed inside the mounting groove;

[0008] The water level indicating assembly includes a cylinder, which is connected to the water heater tank through a water conduit, and the bottom and top of the cylinder are both provided with conical shells connected thereto, the conical shell at the bottom is arranged inside a mounting groove, and the bottom of the conical shell at the bottom is provided with a connecting pipe connected thereto, and the conical shell at the top is provided with a conical scraper and a limiting plate inside, a second connecting rod is provided on the top of the conical scraper, a connecting assembly is provided on the top of the second connecting rod, the connecting assembly is connected to the first connecting rod, a first through groove and a second through groove are provided on the limiting plate, and a water level indicating buoyancy plate is provided on the limiting plate.

[0009] Furthermore, the mounting groove matches the conical shell.

[0010] Furthermore, the cylinder is provided with scale lines, and the outer side of the cylinder is provided with an exhaust port and a sensor.

[0011] Furthermore, the connecting assembly includes a through hole and a second threaded hole formed on the second connecting rod, and a first threaded hole formed on the first connecting rod. The first connecting rod is inserted into the through hole, and fixing bolts are provided on the second threaded hole and the first threaded hole.

[0012] Furthermore, the diameter of the water level indicating buoyancy disk is smaller than the diameter of the limiting disk, and the diameter of the water level indicating buoyancy disk is larger than the diameter of the second through groove.

[0013] Furthermore, the telescopic assembly includes an electric telescopic rod disposed on the mounting plate, and a telescopic end of the electric telescopic rod is connected to the first connecting rod.

[0014] The technical effects achieved by this utility model are:

[0015] First, the water inside the water heater tank enters the cylinder through the water pipe. Due to the effect of atmospheric pressure, the water level inside the water heater tank is the same as the water level inside the cylinder.

The scraped impurities and scale move to the bottom of the conical shell through the second through groove, and then open the connecting pipe to discharge the impurities and scale. The utility model facilitates the installation of the water level indicator component through the connecting component and the installation groove, thereby saving time and effort.

[0024] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0025] like Figure 1-6 As shown, the technical solution adopted by the utility model is specifically as follows: a water level indicator device for a solar water heater comprises a water heater box 1, two symmetrical mounting plates 2 are arranged outside the water heater box 1, a telescopic component is arranged on the top mounting plate 2, a first connecting rod 3 is installed at the telescopic end of the telescopic component, a mounting groove 4 is opened on the bottom mounting plate 2, and a water level indicator component is installed inside the mounting groove 4;

[0026] The water level indicating assembly includes a cylinder 5, which is connected to the water heater tank 1 through a water conduit 6. A conical shell 7 connected thereto is provided at the bottom and top of the cylinder 5. The conical shell 7 at the bottom is arranged inside the mounting groove 4, and a connecting pipe 8 connected thereto is provided at the bottom of the conical shell 7 at the bottom. A conical scraper 9 is provided inside the conical shell 7 at the top, a second connecting rod 11 is provided at the top of the conical scraper 9, a connecting assembly is provided at the top of the second connecting rod 11, and the connecting assembly is connected to the first connecting rod 3. A limit plate 10 is fixedly provided inside the cylinder 5, a first through groove 12 and a second through groove 13 are provided on the limit plate 10, and a water level indicating buoyancy plate 14 is provided on the limit plate 10.

[0027] Its working principle is as follows: first, the water inside the water heater casing 1 enters the cylinder 5 through the water pipe 6. Due to the effect of atmospheric pressure, the water level inside the water heater casing 1 is the same as the water level inside the cylinder 5. When the water level inside the cylinder 5 rises, the water level indicating buoyancy disk 14 is driven to rise inside the cylinder 5, thereby displaying the water level. However, the water heater casing 1 is generally hot water. At the same time, since the heated water has scale, the hot water will also produce scale when it enters the cylinder 5. The scale is easily adsorbed on the inner wall of the cylinder 5, resulting in resistance to the rise of the water level indicating buoyancy disk 14, resulting in inaccurate water level display. Similarly, the generation of scale makes it unclear when viewed from the outside. For this reason, when people are viewing If it is not clear when observing or the water level display is inaccurate, by starting the telescopic component, the telescopic component drives the first connecting rod 3 so that the connecting component drives the second connecting rod 11 to move, and the second connecting rod 11 drives the conical scraper 9 to move on the inner wall of the cylinder 5, so as to remove the impurities and scale on the inner wall of the cylinder 5, and the scraped impurities and scale move to the inside of the conical shell 7 at the bottom through the second through groove 13, and then open the connecting pipe 8 to discharge the impurities and scale. The traditional water level indicator is generally arranged inside the water heater box 1, which is time-consuming and labor-intensive when repairing and installing. The utility model facilitates the installation of the water level indicator through the connecting component and the installation groove 4, achieving the effect of saving time and labor. The device can not only remove the scale inside the water level indicator, improve the accuracy of the water level display, and facilitate people to observe, but also facilitate the installation of the water level indicator, achieving the effect of saving time and labor.

[0028] The mounting groove 4 matches with the conical shell 7 , and matching here means that the conical shell 7 can be installed inside the mounting groove 4 without shaking or falling off.

[0029] At the same time, the cylinder 5 is made of transparent material, so that people can conveniently observe the water level.

[0030] The cylinder 5 is provided with scale lines 15, through which people can conveniently see which position the water level has reached.

[0031] An exhaust port 16 and a sensor 17 are provided on the outside of the cylinder 5. The exhaust port 16 can make the water level inside the cylinder 5 consistent with the water level inside the water heater tank 1 (that is, the atmospheric pressure is the same). The sensor 17 can prevent the water level from exceeding the maximum range. When the sensor 17 senses that the water level exceeds the requirement, the alarm connected to it will sound an alarm. The alarm is not shown in the figure and belongs to the prior art, so no further elaboration will be made here.

[0032] Furthermore, the diameter of the conical scraper 9 is the same as the diameter of the inner cavity of the cylinder 5. This arrangement enables the outer side of the conical scraper 9 to fit the inner wall of the cylinder 5, thereby scraping off impurities and scale.

[0033] It should be added that: when it is necessary to remove impurities and scale, first open the connecting pipe 8 and close the water conduit 6 to drain the water inside the cylinder 5. At this time, the water level indicating buoyancy disk 14 has no buoyancy and drops onto the limit disk 10. Since the diameter of the water level indicating buoyancy disk 14 is smaller than the diameter of the limit disk 10 and the diameter of the water level indicating buoyancy disk 14 is larger than the diameter of the second through groove 13, the second through groove 13 is blocked when the water level indicating buoyancy disk 14 drops, and the scraped impurities fall through the first through groove 12 into the bottom conical shell 7 and are then discharged through the connecting pipe 8.

[0034] In order to prevent impurities and scale from adhering to the water level indicating buoyancy disk 14 , a conical block made of the same material as the water level indicating buoyancy disk 14 is provided on the top of the water level indicating buoyancy disk 14 , and the conical block can prevent impurities and scale from adhering to the water level indicating buoyancy disk 14 .

[0035] The telescopic assembly includes an electric telescopic rod 22 arranged on the mounting plate 2. The telescopic end of the electric telescopic rod 22 is connected to the first connecting rod 3. The electric telescopic rod 22 drives the first connecting rod 3 to move.

[0036] The connecting assembly includes a through hole 18 and a second threaded hole 19 formed on the second connecting rod 11 and a first threaded hole 20 formed on the first connecting rod 3. The first connecting rod 3 is inserted into the through hole 18. The second threaded hole 19 and the first threaded hole 20 are provided with fixing bolts.

[0037] When making the connection, the first connecting rod 3 is inserted into the through hole 18, at which time the first threaded hole 20 and the second threaded hole 19 are aligned, and then the fixing bolts are inserted into the first threaded hole 20 and the second threaded hole 19 for fixing.

[0038] The diameter of the first connecting rod 3 is smaller than the diameter of the second connecting rod 11 , so that the first connecting rod 3 can drive the second connecting rod 11 to move inside the cylinder 5 .

[0039] The connecting pipe 8 is provided with a sealing cover, and the connecting pipe 8 can be opened and closed by the sealing cover.

[0040] The working principle of the utility model is as follows: first, the water inside the water heater casing 1 enters the cylinder 5 through the water conduit 6. Due to the effect of atmospheric pressure, the water level inside the water heater casing 1 is the same as the water level inside the cylinder 5. When the water level inside the cylinder 5 rises, the water level indicating buoyancy disk 14 is driven to rise inside the cylinder 5, thereby displaying the water level. If people cannot observe clearly or the water level display is inaccurate when watching, the telescopic component is started, and the telescopic component drives the first connecting rod 3 so that the connecting component drives the second connecting rod 11 to move. The second connecting rod 11 drives the conical scraper 9 to move on the inner wall of the cylinder 5, thereby removing the impurities and scale on the inner wall of the cylinder 5. The scraped impurities and scale move to the bottom of the conical shell 7 through the second through groove 13, and then the connecting pipe 8 is opened to discharge the impurities and scale. The utility model facilitates the installation of the water level indicating component through the connecting component and the mounting groove 4, thereby saving time and effort. The device can not only remove scale inside the water level indicator device, improve the accuracy of water level display and facilitate people's observation, but also facilitate the installation of the water level indicator component, thereby achieving the effect of saving time and labor.

[0041] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
