Used as a connecting device between units in large solar collectors

technical field

The utility model relates to a connecting device used for unit bodies in a large-scale solar heat collector, which belongs to the manufacturing field of large-scale solar heat collectors.

Background technique

As we all know, under the same conditions, the amount of heat collected by a solar collector is directly proportional to the area of the collector. The larger the collector, the higher the amount of heat collected. Therefore, for occasions where there is a large demand for heat collection, it is necessary to connect multiple solar collector units to form a large solar collector.

Chinese patent document CN1654900A (invention name: solar collector box integrated assembly and assembly connection structure) provides an embodiment of a large solar collector. As shown in Figure 1, the large-scale solar collector consists of a light-transmitting cover plate 1, an outer sealing strip 2, an extruded profile edge strip 3, a right-angle lining 4, a box bottom surface 5, a frame right-angle block, a sealant, and an edge strip 8. Center seam retainer 9, positioning retainer 10, dripping rib 11, embedding buckle groove 12, rubber pad 13, etc.; extruded profile edge 3 and the outer side of the frame right-angle block are used as center seam retainer 9 or the embedded press-type buckle groove 12 installed by the side retaining strip 8, after the middle seam retaining strip 9 and the side retaining strip 8 are pressed and installed, the retaining strip part just blocks and protects the outer sealing strip 2 at the lower part from sunlight, four A sealant can be filled between the right angle block of the frame and the edge strip 3 of the extruded profile and the inner liner 4 of the right angle. After the secondary sealing, the center seam retaining strip 9 and the side retaining strip play the role of completely covering and protecting the external sealing strip 2, which improves the long-term weather resistance and reliability of the box body and the external sealing strip, and makes the sealing of the light-transmitting cover plate 1 The long-term security is guaranteed, and at the same time, the retaining strip 9 and the side strip 3 play a protective and decorative role on the seam splicing and appearance between the units, and meet the requirements of being a solar energy integrated building component or component.

Then, in this patented product, in addition to the upper frame connection of the two adjacent heat collector units by the middle seam retaining strip 9, the lower end frames must also be connected and positioned, and uniformly installed and fixed to the heat collector mounting bracket and the roof slope. Or on the wall, in order to ensure the stability of the installation of large solar collectors, and then can resist the attack of the storm.

As shown in Fig. 2 and Fig. 3, it is an existing connecting device used for unit bodies in large-scale solar heat collectors. The frame of the solar heat collector unit body is composed of the frame bottom surface 21 at the lower end, the frame vertical plate 22 in the middle, and the upper end with the fastening groove 12 . The connecting device is located between adjacent solar collector units 20 , and includes a support 30 , a pressing block 32 , and a threaded connection consisting of bolts 31 and nuts 33 . The support 30 is a square profile with a continuous T-shaped groove 34 on each side, and the bolt 31 slides from the end surface of the support 30 into the T-shaped groove 34 on the support 30, and the head of the bolt 31 is stuck in the T-shaped groove 34 , the bolt 31 can only move back and forth along the T-shaped slot 34 of the support 30 , but cannot be pulled out from the support 30 . When a large solar collector is installed, first fix the support 30 on the collector mounting bracket, roof slope or wall; then place the frame bottom surface 21 at the lower end of the two adjacent solar collector units on the support 30, of course respectively on both sides of the upper T-shaped groove 34; the bolt 31 slides into the T-shaped groove 34 on the support 30 from the end face of the support 30, and the upper square pressure block 32 and the nut 33 are connected on the bolt 31; The screw thread of nut 33 and bolt 31 is tightened, and bearing 30 and briquetting block 32 jointly clamp and fix the frame bottom surface 21 of solar heat collector unit body, and adjacent solar heat collector unit body is connected; The bar 9 is buckled into the buckle groove 12 to form a closed multi-unit large-scale solar heat collector at last.

However, since there is no uniform product standard in the solar energy industry so far, there is no uniform specification requirement for the solar heat collector unit body, and there are many sizes of the support 30 . This not only causes each solar collector manufacturer to spend a huge amount of money to develop molds and casting supports, but also causes the supports of each manufacturer to be difficult to replace, increasing repair and maintenance costs. In addition, when the existing support 30 is fixed on the heat collector installation bracket, the roof slope or the wall, holes must be drilled on the above-mentioned heat collector installation, roof slope or wall, so that the bolts in the support 30 are inserted in the above-mentioned holes, and are threadedly connected with the nuts on the other side of the collector mounting bracket, roof slope or wall, which is very inconvenient for installation and maintenance. In addition, the pressing block usually adopts the gasket in the bolt and nut connection, the contact pressing area is limited, and the installation and frame connection positioning is not reliable.
