A portable structure from which hunters and wildlife observers can command elevated views of wildlife habitat. Commonly called a blind, it can be constructed as a stand-alone structure and transported intact to habitat sites on, for example a flat-bed truck. It can also be constructed as a trailer, or as a permanent or semi-permanent attachment to a motorized vehicle. The blind offers powered erection, powered access to and from the observation position, and wheelchair accessibility.

A portable observation tower and system of raising and lowering the tower is disclosed. The tower has a tower box with two fixed sectioned front legs and two hinged sectioned back legs. To raise the tower front legs are pulled toward back legs with a winch system mounted on a trailer hitch system. Rolling landing gear is lowered and drawn by winch to a front most locking position. This raises the mid section of tower box reducing the angle of front legs to back legs. Once complete the winch line can be attached to an axle of back legs to draw back legs to front legs. This process elevates tower to its full upright position. Wheels are provided on back legs and on trailer hitch system for movement of the tower. The lowering process occurs in reverse order of the raising process.

The invention discloses a mountain area observation tower device based on wind-solar complementary power generation, and relates to the technical field of power generation equipment. The mountain areaobservation tower device comprises a base platform, and an observation platform is installed on the upper surface of the base platform through stand columns. A first groove is formed in the end faceof the upper part of the observation platform, and the first groove is internally provided with a rotating plate provided with a solar panel. A first lantern ring and a second lantern ring are rotatably arranged on the circumferential side surface of the observation platform, and fixing rods are arranged between the first lantern ring and the second lantern ring in the annular direction. Rotatingblades are connected to the fixing rods. A second groove is formed in the end surface of the lower part of the observation platform, and the second groove is internally and rotatably provided with a gear ring. The gear ring and the second lantern ring are connected by U-shaped rods, and the gear ring internally meshes with a driven gear. The driven gear is connected with a wind driven generator. According to the mountain area observation tower device based on the wind-solar complementary power generation, a solar power generation assembly and a wind energy power generation assembly are combined and arranged on a mountain area observation tower based on the wind-solar complementary power generation technology, and the problem that the mountain area observation tower is difficult to electrify is solved, and the mountain area observation tower device is suitable for popularization.

The invention discloses a tower for observing an atmospheric boundary layer underlayer structure and air-sea flux exchange of an island reef. In combination with the main body structure design of the tower, the instrument mounting structure design and design and implementation of a data observing system, a multisource sensor can be mounted on the observing tower to realize gradient observation of the temperature, the humidity, the air pressure, the wind speed and the wind direction of the bottom layer of a 0-20 meter atmospheric boundary layer underlayer and observation of sensible heat flux, latent heat flux, momentum flux and carbon dioxide flux of an air-sea interface within the radius range of 2,200 meters in the upwind direction. By means of the structure and data acquisition system design, the tower for observing the atmospheric boundary layer underlayer structure and air-sea flux exchange of the island reef has the characteristics that the observation parameters are diversified, corrosion resistance is realized, the system is convenient to maintain in the severe weather process, the observation cost is low and the like, a new means can be provided for observation of boundary layer structures and air-sea flux of the South China Sea, and meanwhile, a foundation is laid for next synchronous networking observation of multiple island reefs.
