The invention discloses a supporting structure of a base for an air conditioner and the air conditioner. The supporting structure comprises a hanging plate and a base which is rotatably connected to the hanging plate, and at least one supporting rod used for supporting the base is installed on the hanging plate; and a rod arm of each supporting rod is provided with a pair of protrusions, the base is provided with a pair of elastic buckles which are used for abutting against the corresponding protrusions after the base is pulled up, and the base is provided with grooves which can be used for allowing the rod arms to be inserted after the base is put down. By means of the above-mentioned structure, when the base is pulled up, the elastic buckles can abut against the protrusions of the rod arms, and support to the base can be achieved; after the base is put down, the rod arms can be inserted into the grooves, in the operation process, support to the base can be achieved without rotating the supporting rods on the hanging plate through an operator, and convenience is brought to the operator. According to the supporting structure, the supporting rods cannot rotate, and the phenomenon that the supporting rods breaks away from the base can be avoided; meanwhile, due to the fact that the rod arms are inserted into the grooves, the phenomenon that the base breaks away from the hanging plate can be avoided.

The invention discloses an easy-to-install lightning protection device for a communication tower. The top of the first support cylinder is fixedly connected with a first support ring, the top of the first support ring is fixedly connected with a plurality of second support cylinders around the top, and the tops of the plurality of second support cylinders are fixedly connected with a second support ring. The beneficial effects of the present invention are: the invention separates the main body of the lightning protection device into three parts: a circular connecting rod, a fixed cylinder and a conical circular platform, effectively avoiding the direct installation of the integrated device, and reducing the time required to transport the integrated lightning rod device to a communication tower at a high place Therefore, the four fixed bottom plates are sequentially fixed on the top of the second support ring, and the circular connecting rods are fixed by four support rods, so as to avoid the new type of shaking when the lightning protection device is used.

The invention relates to a drying and dehydrating system for preparing biomass fuel from crop straws. The system comprises a straight plate, a feeding device, a transmission drying device and a discharging device, the feeding device is mounted on the outer wall of the left end of the straight plate, the discharging device is mounted on the outer wall of the right end of the straight plate, and thetransmission drying device is mounted in the straight plate. According to the system, the following problems during drying and dehydration of crop straws can be solved: 1, at present, domestic crop straws are basically dried and dehydrated on an open-air platform, the straws are dehydrated and aired in an airing mode, the airing effect and the airing time of the straws can be affected by changesof weather, and the straws can be damped again in the airing process; and 2, an existing crop straw drying and dewatering device basically conducts dewatering operation on straws through rotation of adewatering barrel, the dewatering barrel rotates generally to only spin-dry moisture on the outer surface of the straws, and the moisture in the straws is difficult to spin out directly.
