Detailed ways

In order to make the content of the utility model easier to understand clearly, the utility model will be further described in detail below according to the specific embodiments and in conjunction with the accompanying drawings.

As shown in Figures 1 to 5, a drainage type roof photovoltaic module waterproof installation structure includes a main beam 1, a secondary beam 2, a main beam pressing block 3 and a secondary beam pressing block 4, and the main beam pressing block 3 is fixedly connected to the main beam. The top of the beam 1, and there is a main rubber strip clamping groove 13 between the main beam pressing block 3 and the main beam 1, and the main rubber strip clamping groove 13 holds a waterproof rubber strip 6 that can be sleeved on the end of the photovoltaic module 5, The secondary beam 2 is arranged on the main beam 1, and the secondary beam clamping block 4 is fixedly connected to the top of the secondary beam 2, and there is a secondary rubber strip clamping groove 24 between the secondary beam clamping block 4 and the secondary beam 2, and the secondary rubber strip clamping groove 24 There is also a waterproof rubber strip 6 that can be sleeved on the other end of the photovoltaic module 5. The main beam 1 is provided with an upper water diversion groove 1-1 and a lower layer water diversion groove 1-2. The upper layer water diversion groove 1-1 is connected with the main glue The bar clip grooves 13 are interconnected, and the secondary beam 2 is provided with a secondary beam water diversion groove 2-1, and the secondary beam water diversion groove 2-1 is connected with the lower floor water diversion groove 1-2. There are three installation methods for the main beam 1, which are briquetting type, self-tapping and self-rotating type, and bolt pre-tightening type;
