This utility model relates to the technical field of engineering construction, and in particular to a drainage channel structure for expansion joints. It includes: an inter-column drainage channel, disposed between adjacent structural columns, with an inter-column connecting plate; clearance grooves are provided on the sides of adjacent structural columns; the inter-column connecting plate is fixedly connected to a structural beam and embedded in the clearance groove; a first inter-beam drainage channel and a second inter-beam drainage channel are respectively disposed at both ends of the inter-column drainage channel, both disposed between adjacent structural beams; each inter-beam drainage channel has a beam bottom connecting plate, fixedly connected to the bottom of the structural beam; the first inter-beam drainage channel, the inter-column drainage channel, and the second inter-beam drainage channel overlap sequentially to form a slope and are interconnected; an expansion joint waterproofing strip is provided between the beam bottom connecting plate and the bottom of the structural beam. This application has the effect of forming a second line of defense against water seepage in expansion joints, preventing indoor water seepage.

The utility model discloses soybean ridge ditch irrigation water -saving device, including water pipe: water pipe front side is provided with two valve pipes, the front side and rear side of valve pipe all are linked with the connecting pipe, the rear end of connecting pipe is linked with water pipe in rear side, the front end of connecting pipe is linked with the PE hose in front side, the surface of PE hose is installed with a plurality of nozzles, the inner chamber slidingly connected with the flow resistance board of water pipe, the front side and rear side of water pipe inner wall all are fixedly connected with the inclined sealing plate, the flow resistance board is inserted between two inclined sealing plates. The utility model discloses through the cooperation of water pipe, valve pipe and connecting pipe, can supply irrigation water source to the inner chamber of PE hose, and under the cooperation of nozzle, water source is irrigated in crop periphery, and under the cooperation of flow resistance board and lifting assembly, irrigation quantity can be controlled, irrigation position accuracy and irrigation water volume for adjusting for the purpose of water saving can be reached.

This utility model discloses an optical encapsulation cover structure for a laser diode, including an encapsulation cover body. A mounting hole is formed at the top of the encapsulation cover body, and a sealing mechanism is installed inside the mounting hole. Extension blocks are fixedly connected to all four sides of the surface of the encapsulation cover body, and a positioning mechanism is fixedly connected to the bottom of each extension block. The sealing mechanism includes a light-transmitting lens installed inside the mounting hole. In this optical encapsulation cover structure for a laser diode, the surface of the light-transmitting lens is covered with an annular fluororubber, and a support spring is installed inside the annular fluororubber. The elastic potential energy provided by the support spring firmly adheres the annular fluororubber to the external connection structure, thereby improving the sealing performance of the light-transmitting lens connection and preventing air leakage and water seepage at the connection between the light-transmitting lens and the encapsulation cover body due to poor sealing performance.

This utility model discloses a cable positioning device for communication construction, including a metal cable tray. A first communication cable is installed inside the metal cable tray. Fixing holes are equidistantly spaced on the top of the metal cable tray. A fixing base plate is fixedly connected to the top of the metal cable tray at the fixing holes. A fixing seat is provided on the top of the fixing base plate. The first communication cable passes through the fixing seat. A connecting seat is fitted onto the top of the fixing seat. A slot is provided on the top of the connecting seat. This utility model relates to the field of photovoltaic power generation communication construction technology, solving the problem that in the prior art, communication cables lack effective positioning and protection when connecting to photovoltaic modules, making the cables susceptible to interference and damage from the external environment during outdoor installation, such as wind, sun, rain erosion, or animal chewing, increasing the failure rate of communication cables and raising the cost and difficulty of later maintenance.
