[0027] A highly sealed solar heat collecting device comprises an outer shell frame, a slot cover, a transparent cover plate, a heat absorbing tube, and a heat absorbing tube support plate. The frame is an integrated rectangular hollow structure. The upper end face and the lower end face of the outer shell frame are provided with a semi-enclosed groove, and the upper and inner sides of the groove are both open. The slot cover is a split structure, and the slot cover comprises a first slot cover, a third slot cover, a second slot cover, and a fourth slot cover.

[0028] One side of the first slot cover, the third slot cover, the second slot cover, and the fourth slot cover are respectively connected to the upper side, the lower side, the left side, and the right side of the end of the groove, one end of the first slot cover is pressed above one end of the second slot cover, the other end of the second slot cover is pressed above one end of the third slot cover, and the two ends of the fourth slot cover are respectively pressed on the other ends of the first slot cover and the third slot cover, the first slot cover, the third slot cover, the second slot cover, and the fourth slot cover are connected by a mortise and tenon structure, and the fourth slot cover is locked by a fixing sleeve;

[0029] Specifically, in this embodiment, the groove at the edge near the lower part of one end of the slot cover is a protruding part relative to the groove, and this part is a mortise. A transverse step-shaped groove and a through-hole structure are provided at the edge of one end of the slot cover. The through-hole part is used to receive the tenon, and the groove part of the mortise is used to bite with the groove part of the mortise. The first slot cover and the second slot cover have the same structure, one end is a mortise and the other end is a mortise. Both ends of the third slot cover are mortise. Both ends of the fourth slot cover are mortise. When connected, the tenon of the first slot cover is connected to the mortise of the second slot cover, and the two ends of the third slot cover are respectively connected to the mortise of the second slot cover and the fourth slot cover, and the other mortise part of the fourth slot cover is connected to the mortise of the first slot cover.

[0030] One end of the mortise and tenon of the first slot cover and the second slot is pressed by another slot cover, and one side is connected to the outer shell frame, and the mortise and tenon of the other end is pressed on the other slot covers. Although it is limited only by friction, the sealing strip makes the connection between the mortise and tenon tighter and will not fall off. Both ends of the third slot cover are pressed by the mortise and tenon of the other two slot covers and will not fall off. The fourth slot cover is limited only by the friction force of the mortise and tenon connection and is easy to fall off. The falling off of the fourth slot cover will cause the other slot covers to fall off as well. Therefore, locking the fourth slot cover by a fixing sleeve can ensure the stability of the entire structure.

[0031] The fixing sleeve is a U-shaped structure, the two fourth slot covers are located on the same side of the outer shell frame, the fixing sleeve is clamped on the edge of the outer shell frame, the two side plates of the fixing sleeve are respectively connected to the upper end surfaces of the two fourth slot covers, and the fixing sleeve is connected to the outer shell frame by bolts.

[0032] The transparent cover plate, the heat absorbing tube, and the heat absorbing tube support plate are sequentially arranged in the up-down direction, and the transparent cover plate is placed between the slot cover and a groove. In this embodiment, the transparent cover plate is a glass plate. Of course, other materials with good light transmittance can also be used.

[0033] The heat absorbing tube support plate includes a heat insulation plate and a support structure. The heat insulation plate is placed between the slot cover and another slot. The support structure is used to support the heat absorbing tube. The heat absorbing tube is located between the heat insulation plate and the transparent cover plate. The inner walls of the two slots, the lower end surface of the slot cover and the mortise and tenon structure are provided with sealing strips, which are slightly thinner and not shown in the figure. The heat insulation plate is made of non-metallic material, does not conduct heat, and plays a role in heat insulation. The transparent cover plate and the heat insulation plate are both rectangular plate structures with rounded corners for easy installation.

[0034] The heat absorbing tube is a copper tube, and the heat absorbing tube is arranged in a serpentine shape. Both ends of the heat absorbing tube are threaded ends, one end of the heat absorbing tube is located in the upper left part of the outer shell frame, and the other end is located in the lower right part of the outer shell frame. Both ends of the heat absorbing tube are threadedly connected with a joint pipe, which is recorded as a left joint pipe and a right joint pipe. The left joint pipe and the right joint pipe pass through the left and right sides of the outer shell frame respectively, and the left and right sides of the outer shell frame are respectively provided with joint pipe perforations. The left joint pipe and the right joint pipe are connected to the water pipeline or connected to the joint pipe of the adjacent collector, with water entering at one end and water exiting at the other end. The water continuously circulates to absorb heat and becomes hot water for use in the swimming pool.

[0035] The joint pipe perforation is a countersunk hole, and the outer side of the joint pipe perforation forms a sealing ring groove for installing the sealing gasket, which is a step groove. The left joint pipe and the right joint pipe have the same structure and both have a clamping nut. After the corresponding joint pipe is installed, the clamping nut of the joint pipe is used to press tightly on the sealing gasket. The clamping nut is located on the outer side of the shell frame to improve the sealing performance, prevent more heat loss, and thus improve the heat utilization rate.

[0036] The supporting structure adopts a supporting clip, which has a C-shaped hole with an opening facing upward. The size of the C-shaped hole is larger than the size of the concentric semicircular hole, so that the edge of the supporting clip forms a clamping portion. The supporting structure is made of plastic material and has a certain deformability, so that the tube body of the heat absorption tube can be inserted into the slot of the supporting clip from top to bottom. Since it is a large semicircular hole slot, it has a certain fastening effect.

[0037] There are 4 to 6 supporting structures, which are arranged in sequence along the front-to-back direction. In this embodiment, 6 supporting structures are provided to ensure the stability of the heat absorbing tube.

[0038] A fixed horizontal plate is provided on the lower side of the outer shell frame, and both ends of the fixed horizontal plate extend out of the outer shell frame in the left and right directions. Bolt holes are provided on the extended part of the fixed horizontal plate. The bolt holes are long holes for the fixing bolts to pass through, and the fixing position is adjustable.
