[0024] See also Figure 1-Figure 5As shown, a photovoltaic thermal storage heating device comprises a thermal storage box 1; one end of a connecting pipe 2 is fixedly connected to one side of the bottom end of the thermal storage box 1, and the other end of the connecting pipe 2 is fixedly connected to a photovoltaic power generation panel 3, the photovoltaic power generation panel 3 is electrically connected to a voltage conversion device 4, and is electrically connected to the thermal storage box 1 through a connecting cable 5, and an adjustment mechanism is provided at the bottom end of the photovoltaic power generation panel 3;

[0025] The adjusting mechanism comprises a connecting seat 41, the top end of the connecting seat 41 is rotatably connected to the rear side of the bottom end of the photovoltaic power generation panel 3, a support seat 42 is provided on the front side of the bottom end of the photovoltaic power generation panel 3, an active screw rod 43 is rotatably connected to the front end of the connecting seat 41 near the right side, the front end of the active screw rod 43 penetrates the support seat 42, a passive screw rod 44 is rotatably connected to the right side of the front end of the connecting seat 41, and the front end of the passive screw rod 44 is rotatably connected to the rear side of the support seat 42, the outer sides of the active screw rod 43 and the passive screw rod 44 are both threadedly connected with a screw sleeve 45, the top end of the screw sleeve 45 is hinged to the bottom end of the hinge rod 46, and the top end of the hinge rod 46 is hinged to the bottom end of the photovoltaic power generation panel 3, the active screw rod 43 and the passive screw rod 44 are fixedly connected with a pulley 47 near the front end, the outer side of the pulley 47 is provided with a transmission belt 48, and the front end of the active screw rod 43 is provided with a control component;

[0026] During operation, the knob 52 is turned to drive the gear 51 to rotate synchronously. When the gear 51 rotates, it drives the active screw 43 to rotate synchronously through the tooth groove 50. When the active screw 43 rotates, it drives the passive screw 44 to rotate synchronously through the combination of the pulley 47 and the transmission belt 48. When the active screw 43 and the passive screw 44 rotate, they drive the screw sleeve 45 connected to their outer thread to move. The screw sleeve 45 pushes the hinge rod 46 to move, so that the hinge rod 46 lifts the photovoltaic panel 3 upward, and the photovoltaic panel 3 rotates at the position rotatably connected to the connecting seat 41, thereby adjusting the angle of the photovoltaic panel 3, so that the photovoltaic panel 3 can have a better conversion efficiency in areas with different latitudes and in different seasons.

[0027] Further, the control component includes a tooth groove 50, which is provided on the outer side of the front end of the active screw rod 43, and the tooth groove 50 is meshed with a gear 51, one side of the gear 51 is engaged with a limit block 54, a slider 56 is fixedly connected to the rear side of the limit block 54, the slider 56 is sleeved on the outer side of a guide rod 57, the guide rod 57 is fixedly connected to the inside of a slide groove 58, and a spring 59 is wound around the outer side of the guide rod 57, and the slide groove 58 is provided on the front side of the support seat 42; a knob 52 is fixedly connected to the front end of the gear 51, and the rear end of the gear 51 is rotatably connected to the front side of the support seat 42;

[0028] When the angle of the photovoltaic panel 3 is to be adjusted, the pull plate 55 is first pulled to drive the limit block 54 to move, so that the slider 56 fixedly connected to it moves synchronously with the movement of the limit block 54 in the slide groove 58, and squeezes the spring 59, so that the spring 59 produces elastic deformation under the action of the squeezing force, at this time, the limit block 54 is released from the state of being engaged with the gear 51, and the rotation of the gear 51 is limited. At this time, the angle of the photovoltaic panel 3 can be adjusted by rotating the knob 52. When the angle of the photovoltaic panel 3 is adjusted to the specified position, the pull plate 55 is released, so that the slider 56 returns to its original position under the action of the restoring force of the spring 59 and drives the limit block 54 to move synchronously to its original position. At this time, the limit block 54 is re-engaged with the gear 51, which limits the rotation of the gear 51 and fixes the angle of the photovoltaic panel 3, thereby avoiding the deviation of the angle of the photovoltaic panel 3 due to the accidental touch of the rotating knob 52.

[0029] Furthermore, an anti-slip cover 53 is glued to the outer side of the knob 52, and an anti-slip pattern is provided on the outer side of the anti-slip cover 53;

[0030] During operation, the anti-skid cover 53 made of rubber and the anti-skid grooves on the outer side of the anti-skid cover 53 increase the friction force, thereby preventing the knob 52 from slipping due to too little friction force when being rotated.

[0031] Furthermore, a pull plate 55 is fixedly connected to the front end of the limit block 54, and the pull plate 55 is made of plastic; the side of the spring 59 close to the slider 56 is fixedly connected to the slider 56, and the side of the spring 59 away from the slider 56 is fixedly connected to the inner wall of the slide groove 58.

[0032] Working principle: when the angle of the photovoltaic panel 3 is to be adjusted, the pull plate 55 is first pulled to drive the limit block 54 to move, so that the slider 56 fixedly connected to it moves synchronously with the movement of the limit block 54 inside the slide groove 58, and squeezes the spring 59, so that the spring 59 produces elastic deformation under the action of the squeezing force, at this time, the limit block 54 is released from the state of being engaged with the gear 51, and the rotation of the gear 51 is limited. At this time, the angle of the photovoltaic panel 3 can be adjusted by rotating the knob 52. When the angle of the photovoltaic panel 3 is adjusted to the specified position, the pull plate 55 is released, so that the slider 56 returns to its original position under the action of the restoring force of the spring 59 and drives the limit block 54 to move synchronously to its original position. At this time, the limit block 54 is re-engaged with the gear 51, which limits the rotation of the gear 51 and fixes the angle of the photovoltaic panel 3, thereby avoiding the deviation of the angle of the photovoltaic panel 3 due to accidental touching of the rotating knob 52.

[0033] After contacting the limit of the gear 51, turning the knob 52 drives the gear 51 to rotate synchronously. When the gear 51 rotates, the active screw 43 is driven to rotate synchronously through the tooth groove 50. When the active screw 43 rotates, it drives the passive screw 44 to rotate synchronously through the combination of the pulley 47 and the transmission belt 48. When the active screw 43 and the passive screw 44 rotate, they drive the screw sleeve 45 connected to the outer thread to move. The screw sleeve 45 pushes the hinge rod 46 to move, so that the hinge rod 46 lifts the photovoltaic panel 3 upward, and the photovoltaic panel 3 rotates at the position where it is rotatably connected to the connecting seat 41, thereby adjusting the angle of the photovoltaic panel 3, so that the photovoltaic panel 3 can have a better conversion efficiency in areas with different latitudes and in different seasons.

[0034] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
