By adopting the solar water heater provided by the embodiment of the disclosure, the water tank frame 100 is installed through the cooperation of the front support leg 200 and the rear support leg 300, and the rear support leg 300 is divided into the first leg part 310 and the second leg part 320 which are connected in a rotating way, so that the rotation angle between the first leg part 310 and the second leg part 320 can be adjusted adaptively according to different gradients of installation environments to adjust the height difference of the lower ends of the front support leg 200 and the rear support leg 300, thereby enabling the front support leg 200 and the rear support leg 300 to adapt to different installation environments. By means of rotating and adjusting the first leg 310 and the second leg 320, the support height of the rear leg 300 can be finely adjusted, the adjustment process of the support height of the solar water heater is simplified, and the installation efficiency is improved.

Optionally, the solar water heater further comprises: a water reservoir 400. The water storage tank 400 is provided inside the tank frame 100. In this way, the water tank 400 is used for storing hot water for users, and the water tank frame 100 is used for supporting the water tank 400, so that the overall stability of the solar water heater is improved.

Like this, set up water tank frame 100 into arc seat 110 and connecting seat 120, arc seat 110 is used for bearing water storage tank 400, makes the stability of water storage tank 400 higher, is difficult for taking place to empty in external environment and drops. The connection base 120 connected with the arc-shaped base 110 is provided at the lower side thereof, and the connection stability of the front leg 200 and the rear leg 300 can be improved by connecting the connection base 120 with the upper ends of the front leg 200 and the rear leg 300.

Optionally, the upper sidewall of the connection base 120 is adapted to the shape of the lower sidewall of the arc base 110. In this way, the connection stability between the arc-shaped base 110 and the connection base 120 can be improved, and the overall stability of the water tank frame 100 can be further improved.

Specifically, the water storage tank 400 is a cylindrical structure, and the radian of the inner side wall of the arc-shaped seat 110 is adapted to the radian of the outer side wall of the water storage tank 400. Thus, the water storage tank 400 of the cylindrical barrel structure is installed in the external environment with relatively small windward area and high stability. The radian of the inner side wall of the arc-shaped seat 110 is matched with the radian of the outer side wall of the water storage tank 400, so that the contact area between the water storage tank 400 and the arc-shaped seat 110 can be increased, and the installation stability of the water storage tank 400 is further improved.

Optionally, the front leg 200 is disposed obliquely, and an upper sidewall of the front leg 200 is provided with a heat collecting pipe mounting bracket 210. In this way, the heat collecting pipe mounting frame 210 is arranged on the upper side wall of the front supporting leg 200 and is used for mounting water stored in the heat collecting pipe heating water storage tank 400, and the front supporting leg 200 is obliquely arranged, so that the heat collecting pipe mounting frame 210 on the upper side wall of the front supporting leg 200 can be exposed to sunlight in a larger area, and the solar energy utilization rate is improved.

Specifically, a heat collecting pipe is installed inside the heat collecting pipe mounting frame 210, and the heat collecting pipe communicates with the water storage tank 400. In this way, the heat collecting tube is supported by the heat collecting tube mounting frame 210, and the water in the heat collecting tube is heated by collecting solar energy by the heat collecting tube, so that the supply of hot water is satisfied.

Optionally, a plurality of tube slots are disposed inside the heat collecting tube mounting frame 210, and heat collecting tubes are disposed in the tube slots. Thus, a plurality of tube grooves are formed in the inner side of the heat collecting tube mounting frame 210, heat collecting tubes are mounted in the tube grooves for use, and solar energy is collected by the heat collecting tubes to heat water, so that the heating efficiency of hot water is improved, and the supply amount of hot water is increased.

Specifically, the plurality of tube grooves are arranged in parallel with each other, and the heat collecting tubes installed in the plurality of tube grooves are all communicated with the water storage tank 400.

Optionally, the rear leg 300 is also inclined, and the front leg 200 is inclined to one side along the central axis of the tank frame 100 in the vertical direction, and the rear leg 300 is inclined to the other side along the central axis of the tank frame 100 in the vertical direction. In this way, the front and rear legs 200 and 300 are formed to support the tank frame 100 in a bifurcated form, further improving the support stability of the front and rear legs 200 and 300.

Specifically, an inclination angle between the front leg 200 and the central axis of the tank frame 100 in the vertical direction is greater than an inclination angle between the rear leg 300 and the central axis of the tank frame 100 in the vertical direction. In this way, since the upper side wall of the front leg 200 is provided with the heat collecting tube mounting frame 210, the heat collecting tube needs to fully receive the irradiation of the sunlight, so that the inclination angle of the front leg 200 is set larger, the heat collecting tube positioned on the upper side wall of the front leg 200 fully receives the irradiation of the sunlight, and the solar energy utilization rate is improved.

It will be appreciated that the inclination angle between the rear leg 300 and the central axis of the tank frame 100 in the vertical direction means: in the case where the first and second leg portions 310 and 320 of the rear leg 300 are rotated to the parallel positions, the rear leg 300 is inclined at an angle with respect to the central axis of the tank frame 100 in the vertical direction.

Optionally, the upper end of the front leg 200 is rotatably connected to the water tank frame 100 so that the heat collecting pipe mounting bracket 210 of the upper side wall of the front leg 200 can adjust the inclination angle. Thus, due to the fact that the sunlight irradiation angles of different regions and different seasons are different, the upper ends of the front support legs 200 are rotationally connected with the water tank frame 100, the inclination angle of the front support legs 200 can be adjusted according to the sunlight irradiation angles, and accordingly the inclination angle of the heat collecting tube on the upper side wall of the front support legs 200 is adjusted, and the solar energy utilization rate of the heat collecting tube is further improved.

Specifically, the upper end of the front leg 200 is rotatably connected to the tank frame 100 through a bearing structure, and a locking structure is provided at the bearing structure. In this way, the rotational stability of the front leg 200 can be improved, and when the front leg 200 rotates to the target position, the bearing structure is locked by the locking structure to fix the front leg 200, thereby improving the overall stability of the solar water heater.

Specifically, the upper end of the front leg 200 is rotatably connected to the connection base 120 through a bearing structure. In this way, since the water tank stand 100 is divided into the arc-shaped seat 110 and the connection seat 120, the arc-shaped seat 110 serves to support the water storage tank 400, and the connection seat 120 serves to be connected with the front leg 200 and the rear leg 300, the upper end of the front leg 200 is rotatably connected with the connection seat 120 through the bearing structure.

It can be appreciated that the position where the connection base 120 is rotationally connected with the front support leg 200 is provided with a bearing structure, the upper end of the front support leg 200 is provided with a connection shaft corresponding to the position of the bearing structure, and the connection shaft is arranged in the bearing structure in a penetrating manner, so that the upper end of the front support leg 200 is rotationally connected with the connection base 120, and a locking structure is arranged at the bearing structure, so that the connection base 120 can be locked, and the front support leg 200 is fixed.

Optionally, the outer wall of the water reservoir 400 is rotatably connected to the inner wall of the tank frame 100. Like this, because install the heat collecting pipe in the heat collecting pipe mounting bracket 210 of preceding landing leg 200 upside, and heat collecting pipe and water tank 400 intercommunication, therefore when preceding landing leg 200 adjusts inclination, the heat collecting pipe also can carry out inclination's regulation along with preceding landing leg 200, in order to ensure the normal intercommunication of heat collecting pipe and water tank 400, rotate the outer wall of water tank 400 with the inner wall of water tank frame 100 to be connected, when the heat collecting pipe along with preceding landing leg 200 regulation inclination, water tank 400 also can rotate in water tank frame 100 along with the heat collecting pipe.

Specifically, the outer wall of the water storage tank 400 is rotatably connected with the inner wall of the arc-shaped seat 110 of the water tank frame 100.

Specifically, the inner side wall of the arc-shaped seat 110 is embedded with a plurality of balls, and the outer side wall of the water storage tank 400 is abutted against the plurality of balls. In this way, the friction force between the outer side wall of the water storage tank 400 and the inner side wall of the arc-shaped seat 110 can be reduced, and when the inclination angle of the heat collection pipe is adjusted along with the front supporting leg 200, the water storage tank 400 can rotate along with the heat collection pipe more smoothly, so that the fracture risk of the joint of the heat collection pipe and the water storage tank 400 is reduced.

Specifically, the side wall of the arc-shaped base 110 facing the heat collecting tube mounting frame 210 has a plurality of through grooves, and each heat collecting tube passes through the corresponding through groove to be communicated with the water storage tank 400. In this way, the arc-shaped seat 110 can be prevented from blocking the movement of the heat collecting tube, so that the heat collecting tube can be smoothly rotated and adjusted along with the front support leg 200.

Optionally, as shown in fig. 1, the solar water heater further includes: supporting the cross beam 500. The support cross member 500 has one end connected to the front leg 200 and the other end connected to the rear leg 300. In this way, the front leg 200 and the rear leg 300 are connected by the support cross member 500, so that the support stability of the front leg 200 and the rear leg 300 can be improved, and the front leg 200 and the rear leg 300 are prevented from being deformed due to excessive stress.

Optionally, one end of the support cross member 500 is rotatably connected to the front leg 200. Thus, since the upper end of the front support leg 200 is rotatably connected with the water tank frame 100, the rotation adjustment can be performed, and therefore, one end of the support beam 500 is rotatably connected with the front support leg 200, and when the front support leg 200 is rotatably adjusted, the connection part of the support beam 500 and the front support leg 200 can rotate, so that the support beam 500 is prevented from blocking the rotation of the front support leg 200, and smooth adjustment of the front support leg 200 is ensured.

Specifically, the side wall of the front supporting leg 200 is provided with a shaft seat, one end of the supporting beam 500 is provided with a rotating shaft, and one end of the rotating shaft is inserted into the shaft seat and is rotationally connected with the shaft seat. In this way, the axle seat is arranged on the side wall of the front supporting leg 200, the rotating axle is arranged at one end of the supporting beam 500, and the rotating axle is arranged in the axle seat in a penetrating manner so as to realize the rotating connection between the supporting beam 500 and the front supporting leg 200, so that the stability of the supporting beam 500 is improved.

Optionally, as shown in fig. 2, the supporting beam 500 includes: a storage portion 510 and a telescopic portion 520. The storage part 510 defines a storage groove 530 therein, one end of the storage part 510 is connected with the rear leg 300, and the other end has a storage opening; one end of the telescopic part 520 is rotatably connected with the front leg 200, and the other end is telescopically arranged in the accommodating groove 530 through the accommodating opening. Thus, since the front leg 200 can be rotatably adjusted in its inclination angle, the support cross member 500 pulls the front leg 200 to restrict its rotation when the front leg 200 is rotatably adjusted. Therefore, the supporting beam 500 is configured as the accommodating portion 510 and the telescopic portion 520, one end of the telescopic portion 520 is rotatably connected with the front leg 200, and when the front leg 200 is rotatably adjusted, the telescopic portion 520 can extend out of or retract into the accommodating groove 530 of the accommodating portion 510 along with the rotation of the front leg 200, and the supporting beam 500 is used for supporting the front leg 200 and the rear leg 300, and at the same time, the supporting beam 500 is prevented from blocking the adjustment of the front leg 200.

Specifically, one end of the telescopic part 520 is provided with a rotating shaft, and is rotatably connected with the shaft seat of the side wall of the front supporting leg 200.

Optionally, the supporting beam 500 further includes: locking knob 540. The locking knob 540 is disposed on a side wall of the accommodating portion 510, and an end portion of the locking knob 540 passes through the side wall of the accommodating portion 510 and protrudes into the accommodating groove 530. In this way, the telescopic portion 520 in the accommodating groove 530 can be locked by the rotation of the locking knob 540, and when the front leg 200 is rotated and adjusted, the locking knob 540 is rotated to unlock the end portion of the telescopic portion 520 away from the side wall of the telescopic portion 520 so that the telescopic portion 520 can be extended along with the front leg 200. When the front leg 200 is rotated to the target position, the rotation lock knob 540 is rotated toward the telescopic portion 520, and the end portion thereof is abutted against the side wall of the telescopic portion 520, so that the telescopic portion 520 is fixed, and the front leg 200 and the rear leg 300 are supported by the cooperation of the telescopic portion 520 and the storage portion 510.

Alternatively, as shown in fig. 1, the upper end of the first leg 310 is fixedly coupled with the tank frame 100, and the lower end of the first leg 310 is rotatably coupled with the upper end of the second leg 320; in the case where the second leg portion 320 is rotated to a position in line with the first leg portion 310, the lower end of the second leg portion 320 is the same height as the lower end of the front leg portion 200. In this way, the upper end of the first leg portion 310 is fixedly connected to the tank frame 100, the upper end of the second leg portion 320 is rotatably connected to the lower end of the first leg portion 310, and when the support height of the rear leg portion 300 is adjusted, the second leg portion 320 is driven to rotate relative to the first leg portion 310, thereby adjusting. When the second leg portion 320 is rotated to a position in line with the first leg portion 310, at this time, the second leg portion 320 is parallel to the first leg portion 310, and the lower end of the second leg portion 320 is at the same height as the lower end of the front leg portion 200, so that the front leg portion 200 and the rear leg portion 300 cooperate to be able to accommodate a horizontal installation environment.

It will be appreciated that the second leg 320 can be rotated to a position in which it is in line with the first leg 310 and rotated to a position in which it overlaps the first leg 310, in which both the second leg 320 and the first leg 310 are in parallel, and in which the support height of the rear leg 300 is the support height of the first leg 310 plus the support height of the second leg 320 when the second leg 320 is in line with the first leg 310, and in which the support height of the rear leg 300 is the support height of the first leg 310 when the second leg 320 overlaps the first leg 310. The second leg 320 may also be rotated to any oblique angle with respect to the first leg 310.

Specifically, the length of the first leg portion 310 is greater than or equal to the length of the second leg portion 320 in the vertical direction. Thus, the second leg portion 320 can be smoothly rotated to a position overlapping the first leg portion 310.

Alternatively, as shown in fig. 5, a first shaft hole 311 is formed at the lower end of the first leg 310, a second shaft hole 321 is formed at the upper end of the second leg 320, and a rotating shaft 330 is inserted into the first shaft hole 311 and the second shaft hole 321; a plurality of clamping grooves 312 are formed in the outer periphery of the first shaft hole 311, an elastic protruding seat 322 is formed in the outer periphery of the second shaft hole 321, and the elastic protruding seat 322 can be clamped into any clamping groove 312 to fix the second leg 320. In this way, the rotational connection between the first leg portion 310 and the second leg portion 320 is achieved by the rotation shaft 330 sequentially passing through the first shaft hole 311 and the second shaft hole 321, and the connection stability between the first leg portion 310 and the second leg portion 320 can be improved. A plurality of locking grooves 312 are provided on the outer periphery of the first shaft hole 311, an elastic protrusion 322 is provided on the outer periphery of the second shaft hole 321, and the elastic protrusion 322 can be locked into any locking groove 312 to fix the second leg 320 as the second leg 320 rotates, thereby fixing the second leg 320.

Specifically, the plurality of clamping grooves 312 are uniformly distributed along the circumferential direction of the first shaft hole 311. In this way, when the second leg 320 rotates relative to the first leg 310, the elastic boss 322 also rotates along with the second leg 320 in the circumferential direction of the first shaft hole 311, so that the elastic boss 322 can be smoothly engaged into any one of the engaging grooves 312, and the second leg 320 is fixed to make finer adjustment of the support height of the rear leg 300.

Specifically, the elastic protruding seat 322 is partially embedded in the sidewall of the second leg 320 corresponding to the outer periphery of the second shaft hole 321, and a spring is disposed at an end of the elastic protruding seat 322 located in the sidewall of the second leg 320. In this way, the elastic protrusion base 322 can be more firmly clamped in the clamping groove 312 by providing elastic force by the spring, so as to improve the fixing stability of the second leg 320.

Specifically, the end of the elastic protrusion base 322 facing the clamping groove 312 has a hemispherical structure. Thus, when the second leg 320 is forced to rotate, the elastic protrusion seat 322 can be smoothly separated from the clamping groove 312, so that the rotation adjustment of the second leg 320 is facilitated.

Alternatively, as shown in fig. 3, the lower ends of the front leg 200 and the rear leg 300 are each provided with a mount 600. Thus, when the water tank frame 100 is installed through the front leg 200 and the rear leg 300, the installation base 600 can facilitate the fixing of the lower ends of the front leg 200 and the rear leg 300 to the roof, further improving the stability of the solar water heater and the installation efficiency.

Specifically, the mount 600 at the lower ends of the front leg 200 and the rear leg 300 are rotatably connected thereto. In this way, the lower ends of the front and rear legs 200, 300 can be installed to accommodate different grade roofs.
