Description

Technical Field

[0001] The utility model relates to the technical field of solar water heaters, in particular to a pressure-bearing solar shell structure with an anti-blocking prompting function. Background Art

[0002] Solar water heaters are heating devices that convert sunlight into heat energy, heating water from low temperature to high temperature to meet people's hot water needs 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, accounting for 95% of the domestic market share.

[0003] like Figure 4 As shown, it is the previous generation of pressurized solar shell structure. In order to facilitate the staff to understand the internal situation of the shell, visual windows are set on both ends of the original outer shell. Although the staff can visually understand whether there are impurities inside the outer shell, they cannot judge whether the impurities block the pipeline and whether the liquid pressure inside the shell is abnormal, resulting in the staff being unable to clearly judge the internal pressure of the shell.

[0004] In view of this, it is particularly important to design and manufacture a shell structure that can effectively detect whether there is a blockage in a pressurized solar water heater. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that the traditional pressure-bearing solar shell structure can judge whether there are impurities inside the shell, but it is unclear whether the impurities block the pipeline and cause abnormal pressure inside the shell, and to propose a pressure-bearing solar shell structure with an anti-blocking prompt function.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A pressure-bearing solar shell structure with an anti-blocking prompt function comprises an outer shell, a side cover fixed to the end of the outer shell, a connecting pipe installed on the side cover and connected to the outer shell, a plurality of connecting seats equidistantly arranged on the outer end surface of the outer shell, a heat storage and insulation layer filled between the outer shell and the side cover, and visual windows installed on both sides of the upper end of the outer shell and connected to the outer shell, wherein a mounting buckle groove is provided in the middle of the upper end of the outer shell, a mounting buckle plate is installed on the inner side of the mounting buckle groove, and a pressure measuring mechanism for detecting the liquid pressure inside the outer shell is provided on the mounting buckle plate.

[0008] As a further description of the above technical solution:

[0009] The pressure measuring mechanism includes a plunger pressure box integrally fixed in the middle of the mounting buckle plate, a plunger block movably mounted on the inner side of the plunger pressure box, a glass lens mounted on the upper end of the plunger pressure box and located above the plunger block, and an elastic support portion arranged between the plunger pressure box and the plunger block.

[0010] As a further description of the above technical solution:

[0011] The elastic support part includes a guide slide cylinder integrally fixed on the inner side of the plunger pressure box and facing the plunger block, a guide slide rod installed on the inner end of the plunger block and fitted with the guide slide cylinder, and a spiral extrusion spring sleeved on the outer side of the guide slide cylinder and located between the plunger pressure box and the plunger block.

[0012] As a further description of the above technical solution:

[0013] One end of the plunger pressure box facing the plunger block is detachably mounted with a limit stop column abutting against the outer wall of the plunger block.

[0014] As a further description of the above technical solution:

[0015] The upper end of the plunger pressure box is located on both sides of the glass lens and is fixedly connected with a plurality of scale bars for displaying liquid pressure data at equal distances. The middle part of the plunger block is provided with an inner groove for comparison with the scale bars.

[0016] As a further description of the above technical solution:

[0017] A sealing portion is provided between the mounting buckle plate and the outer shell body and is used for the mounting buckle plate to be installed in the mounting buckle groove for comprehensive sealing.

[0018] As a further description of the above technical solution:

[0019] The sealing part includes an external sealing strip installed on the outer edge of the mounting buckle plate, an external sealing groove opened below the mounting buckle groove and corresponding to the external sealing strip, an internal sealing strip installed between the lower end of the mounting buckle plate and the plunger pressure box, and an internal sealing groove opened below the mounting buckle groove and corresponding to the internal sealing strip.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0021] In the utility model, the original pressure-bearing solar shell structure is scientifically and rationally improved, and installation buckle grooves, installation buckle plates, plunger pressure boxes, plunger blocks, spiral extrusion springs and glass lenses are arranged on the outer shell. Under normal circumstances, the liquid pressure inside the outer shell is the same as the internal pressure of the entire hot water system, and the position of the plunger block in the plunger pressure box will also remain constant. When there is a blockage problem inside a certain outer shell, the pressure inside the outer shell will increase. Under the action of the internal pressure, the plunger block will slide inward and squeeze the spiral extrusion spring. The spiral extrusion spring will generate a reverse elastic force to resist the internal pressure. The internal pressure inside the outer shell can be directly understood through the position of the plunger block. This structure can convert the liquid pressure inside the outer shell into the displacement of the plunger block inside the plunger pressure box, so that the staff can intuitively understand whether there is a problem of impurity blockage inside the outer shell, effectively reducing the workload and difficulty of the staff's actual inspection, thereby improving the convenience of daily inspection and maintenance of the pressurized solar water heater.

[0028] 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 of 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.

[0029] See also Figure 1-3 The utility model provides a technical solution: a pressure-bearing solar shell structure with an anti-blocking prompt function, comprising an outer shell 1, a side cover 101 fixed to the end of the outer shell 1, a connecting pipe 102 installed on the side cover 101 and connected to the outer shell 1, a plurality of connecting seats 103 equidistantly arranged on the outer end surface of the outer shell 1, a heat storage and insulation layer 2 filled between the outer shell 1 and the side cover 101, and a visual window 104 installed on both sides of the upper end of the outer shell 1 and connected to the outer shell 1, a mounting buckle groove 105 is opened in the middle of the upper end of the outer shell 1, a mounting buckle plate 3 is installed on the inner side of the mounting buckle groove 105, and a pressure measuring mechanism for detecting the internal liquid pressure of the outer shell 1 is arranged on the mounting buckle plate 3.

[0030] Specifically, Figure 1-3 As shown, the pressure measuring mechanism includes a plunger pressure box 4 integrally fixed to the middle of the mounting buckle plate 3, a plunger block 5 movably mounted on the inner side of the plunger pressure box 4, a glass lens 401 mounted on the upper end of the plunger pressure box 4 and located above the plunger block 5, and an elastic support portion arranged between the plunger pressure box 4 and the plunger block 5, the elastic support portion including a guide slide 404 integrally fixed to the inner side of the plunger pressure box 4 and facing the plunger block 5, and a guide slide rod mounted on the inner end of the plunger block 5 and in contact with the guide slide 404. 502 and a spiral extrusion spring 6 which is sleeved on the outside of the guide slide 404 and located between the plunger pressure box 4 and the plunger block 5. The end of the plunger pressure box 4 which faces the plunger block 5 is detachably mounted with a limit stop column 403 which abuts against the outer wall of the plunger block 5. On the one hand, it can limit the initial position of the plunger block 5 in the plunger pressure box 4. On the other hand, it can prevent the elastic extrusion force of the spiral extrusion spring 6 from causing the plunger block 5 to slide away from the plunger pressure box 4, thereby improving the stability of the actual operation of the plunger pressure box 4.

[0031] Among them, the upper end of the plunger pressure box 4 is located on both sides of the glass lens 401 and is equidistantly fixedly connected with a plurality of scale bars 402 for displaying liquid pressure data. The middle part of the plunger block 5 is provided with an inner groove 501 for comparison with the scale bars 402. The arrangement of the inner groove 501 and the plurality of scale bars 402 facilitates the staff to intuitively judge and measure the displacement of the plunger block 5 inside the plunger pressure box 4, so as to understand the liquid pressure in the outer shell 1.

[0032] Specifically, Figure 1-3As shown, a sealing portion for installing the mounting buckle plate 3 into the mounting buckle groove 105 for comprehensive sealing is provided between the mounting buckle plate 3 and the outer shell 1, and the sealing portion includes an external sealing strip 301 installed on the outer edge of the mounting buckle plate 3, an external sealing groove 106 opened below the mounting buckle groove 105 and corresponding to the external sealing strip 301, an internal sealing strip 302 installed between the lower end of the mounting buckle plate 3 and the plunger pressure box 4, and an internal sealing groove 106 opened below the mounting buckle groove 105 and corresponding to the internal sealing strip 302. 07. When the mounting plate 3 is fixed to the mounting groove 105 by fasteners, the external sealing strip 301 and the internal sealing strip 302 on the mounting plate 3 will be respectively buckled into the external sealing groove 106 and the internal sealing groove 107. At this time, a sealed cavity will be generated between the mounting plate 3 and the mounting groove 105, thereby performing comprehensive sealing treatment on the mounting plate 3 and the mounting groove 105 to prevent the pressure in the outer shell 1 from causing the liquid to overflow through the connection between the mounting plate 3 and the mounting groove 105.

[0033] Working principle: When in use, the external hot water pipe can establish a liquid pipeline connection with the outer shell 1 through the connecting seat 103, and multiple outer shells 1 can be connected to the hot water pipeline in series or in parallel through the connecting pipe 102. Under normal working conditions, the hot water pipe will heat the liquid in the hot water pipe and the outer shell 1 after absorbing heat, and the heated hot water will circulate into the hot water pipeline. At this time, the overall internal pressure value of the hot water pipeline will be dynamically balanced with the temperature of the hot water, and the pressure inside a single outer shell 1 will also float accordingly. The position of the plunger block 5 in the plunger pressure box 4 will also remain in a follow-up state. The staff will adjust the inner concave portion of the plunger block 5 to adjust the inner pressure of the plunger block 5. By comparing the groove 501 with the scale bar 402 on the plunger pressure box 4, the internal pressure in the outer shell 1 can be roughly understood. When there is a blockage problem inside a certain outer shell 1, the pressure inside the outer shell 1 will increase. Under the action of the internal pressure, the plunger block 5 will slide inward and squeeze the spiral extrusion spring 6. The spiral extrusion spring 6 will produce a reverse elastic force to resist the internal pressure. At this time, the position of the plunger block 5 will be away from the initial position. The staff can observe the position of the plunger block 5 through the glass lens 401, and can directly understand whether there is a blockage problem inside the outer shell 1, so as to perform subsequent disassembly, inspection and maintenance operations on the outer shell 1 at the designated position.
