The invention discloses a cable clamp. The cable clamp comprises a bunching part used for accommodating cables and a wind shield arranged on the bunching part, wherein the wind shield comprises a plurality of detachable blinkers. According to the cable clamp, one side of the bunching part is provided with the wind shield, so that wind can be effectively blocked; furthermore, the blinkers of the wind shield can be dismounted, so that the shape of the wind shield can be conveniently changed.

The invention discloses an optical fiber distribution case which comprises a case body and a cover plate. The cover plate can be buckled on the case body to form a cavity body. An optical fiber adapter is arranged inside the case body. An optical fiber fusion welding disc is arranged on one side of the optical fiber adapter and is provided with a straight welding plate and fiber winding discs which are arranged on two sides of the straight welding plate and stores remaining optical cables in a disc mode. Optical cables enter the case body through a cable inlet to be connected with a distribution tail fiber on the straight welding plate in a welding mode. The distribution tail fiber is connected with a jumper tail fiber through the optical fiber adapter, and the jumper tail fiber is output out of the case body through a cable outlet. An X passive optical network (XPON) optical fiber access device and an optical branching device are arranged on the other side of the optical fiber adapter. The optical fiber distribution case can integrally install devices of an operator and part of devices of electric power telecommunication inside the optical fiber distribution case, and considers communication device installation needs needed by a 'three-in-one network' of electric power telecommunication and an operation enterprise. The optical fiber distribution case can achieve telecommunication service access, and is suitable for a fiber to the home project of a small high-rise area and a high-rise area.

The invention belongs to the technical field of solar energy equipment, and specifically discloses a windproof photovoltaic module bracket. The windproof photovoltaic module bracket includes a photovoltaic module, a base and two mounting plates. The photovoltaic module is mounted on the mounting plates. The upper surface of the base is transparent. A transparent plate is hinged between the two mounting plates. The base is provided with grooves on the two sides thereof, and is provided with a cavity inside. Two sliding blocks are connected into the cavity in a sliding and sealing manner. The cavity between the sliding blocks is filled with liquid which is prone to expansion under heat. A first support plate is hinged to one end of each mounting plate, and a second support plate is hinged tothe other end of each mounting plate. A sliding part is arranged at the bottom end of each first support plate. The sliding parts can be connected into the grooves only in a horizontal sliding manner. A connecting rod is fixedly connected to each first support plate. Each connecting rod is fixedly connected with the corresponding sliding block. Sliding seats are symmetrically arranged on the base. Each second support plate is vertically connected into the corresponding sliding seat. Each second support plate is fixedly connected with the bottom of the corresponding sliding seat through a spring. The invention provides a windproof photovoltaic module bracket with high utilization rate of sunlight.

The invention provides a device for preventing wind, sand, snow and dust, and the method is used for solving the problem that in the prior art, along with the increase in blocked sand soil quantity or blocked snow quantity and the like, the sand-resisting, windproof, dustproof or snow-resisting effect of a protecting net is obviously reduced, and therefore sand prevention, wind prevention, dust prevent or snow prevention cannot be carried out finally. The device for preventing wind, sand, snow and dust comprises a screen plate and a screen plate rack body, wherein two ends of the screen plate rack body are respectively provided with a first mounting hole and a second mounting hole, a first upright column is connected with one end of the screen plate rack body and provided with N first gear holes; a second upright column is connected with the other end of the screen plate rack body; one end of the screen plate rack body passes through the first mounting hole and the first gear hole by virtue of a first fixing piece and is fixed together with the first upright column; and the other end of the screen plate rack body passes through the mounting hole and the second gear hole by virtue of a first fixing piece and is fixed together with the second upright column. The device for preventing wind, sand, snow and dust has the advantage that the height of the screen plate can be increased so as to better perform protection.

The invention discloses a protection device for an agricultural environment information acquisition controller used in the field, comprising a bearing main shaft, a three-stage electric push rod is fixed at the bottom of the bearing main shaft, and a deflection side rod part is installed on the bearing main shaft. The protection device of the agricultural environmental information acquisition controller, in the actual collection and use of agricultural environmental information in the field, when encountering strong winds, the three-stage electric push rod is retracted, and the deflection side rod components are driven to deflect synchronously, and synchronously wind The reel assembly synchronously winds the ground cable, so that the wind vane, anemometer and various components are received into the housing sleeve, and the ground cable is synchronously wound in a tight position, thereby effectively protecting the field agricultural information collection controller from wind. At the same time, the ground cable is synchronously and tightly wound, which can effectively ensure the overall real-time stability of the device, which can effectively improve the service life of the field agricultural environment information acquisition controller and ensure the efficient collection and use of field agricultural environmental information for a long time.
