The utility model discloses a kind of Cantharellus cibarius cultivation spray device, it is related to edible mushroom cultivation tool technical field, including base and multiple cultivation units, cultivation unit includes support pipe, cultivation tray and spray pipe, support pipe is coaxially installed at the center of cultivation tray, rotation shell cover is sealingly rotatably installed at the position of support pipe on cultivation tray upside, the part of support pipe inside rotation shell cover is provided with the water spray hole being communicated with rotation shell cover, spray pipe is horizontally fixed and is communicated with the side end of rotation shell cover, and the side end of spray pipe is axially equidistant and provided with multiple spray orifices.The utility model is set by the cooperation of support pipe, cultivation tray, rotation shell cover and spray pipe, water flow in support pipe enters rotation shell cover from water spray hole, and enters spray pipe, finally, it is sprayed from spray orifice, in this process, since the axis of spray pipe does not intersect with the axis of rotation shell cover, it can be guaranteed that rotation shell cover is along the axis of support pipe and stably rotates with spray pipe, and realizes comprehensive spraying.

This utility model discloses a convenient pipe connection structure for pump rooms, relating to the field of pipe technology. The utility model includes a first pipe and a second pipe disposed on the right side of the first pipe, and further includes: an anti-detachment part disposed on both the first and second pipes; a self-sealing part installed inside both the first and second pipes; the anti-detachment part includes an anti-detachment connection component disposed on both the first and second pipes; and a sealing component installed on both the first and second pipes. By incorporating the anti-detachment part, this utility model solves the problem of existing connection structures being inconvenient to prevent the two pipe sections from detaching during use. Relying solely on simple threads for connection, the pipes can detach during operation due to water flow impact, vibration, and other factors, thus increasing equipment failure, safety accidents, and maintenance costs caused by pipe detachment or leakage.

The utility model provides a moisture-proof relay protection wiring junction box, which relates to the technical field of junction boxes, and comprises a box body, a wiring seat fixedly arranged in the box body, a plurality of threading holes arranged on the side wall of the box body, locking assemblies arranged at the threading holes, a plurality of pairs of sealing plates arranged on the inner wall of the box body in a sliding manner, and a connecting sleeve sleeved on a wire, the connecting sleeve is provided with an abutting inclined circumferential surface and an annular groove, a trapezoidal sliding disc is installed in the annular groove in a sliding mode, the outer circumferential surface of the trapezoidal sliding disc is provided with a reset inclined circumferential surface, and the connecting sleeve is provided with a rubber sealing sleeve matched with the outer circumferential surface of an electric wire. And in cooperation with the connecting sleeve, the sealing connection between the electric wire and the box body is realized.

This utility model provides a fire pump connection device, relating to the technical field of fire pump connection devices. It includes a pipe body with a buffer mechanism on its outer surface. The buffer mechanism includes a buffer pipe, and a positioning pipe is connected to the upper surface of the buffer pipe. A lifting plate is slidably connected to the inner surface of the positioning pipe, and a limit post is fixedly connected to the upper surface of the lifting plate. A water outlet pipe is connected to the outer surface of the positioning pipe, and a positioning plug is slidably connected to the inner surface of the water outlet pipe. A support frame is fixedly connected to the inner surface of the water outlet pipe, and two first springs are fixedly connected to the outer surface of the support frame. This utility model, through the buffer mechanism, the cooperation of the first springs and the push rod with the positioning plug, achieves automatic sealing of the water outlet pipe in the non-working state, effectively preventing dust from entering and clogging the pipe or damaging components. It eliminates the need for an additional sealing cap, simplifying the structure while improving the practicality and service life of the equipment.

This invention discloses a safe and explosion-proof energy storage cabinet and method based on an Internet of Things (IoT) system, belonging to the field of energy storage technology. The safe and explosion-proof energy storage cabinet based on an IoT system includes a base plate, and further includes: a cabinet assembly disposed on the top of the base plate; a mounting frame disposed on the cabinet assembly; a nitrogen replenishment assembly disposed inside the mounting frame, with its fixed end disposed on the inner wall of the cabinet assembly; a support rod fixed to the top of the base plate, with its top end connected to the cabinet assembly; an exhaust assembly disposed on the top of the support rod and penetrating the top wall of the cabinet assembly; and storage components disposed on both sides of the top of the base plate. This invention, by supplying nitrogen gas to the cabinet interior to replace the internal air after the door is closed, can significantly improve the safety and stability of the safe and explosion-proof energy storage cabinet based on the IoT system. Nitrogen, as an inert gas, effectively prevents the risk of fire and explosion, and reduces dangers caused by battery failure or other reasons.

A mixture is placed in a cup hole of a cup body of the sintering cup, sintering grate bars are arranged at the end, away from a cup opening, of the cup body, gaps of the sintering grate bars communicate with the cup hole, and the air draft requirement in the sintering process is met. The material distribution pipe is movably inserted into the cup hole, the mixture is placed in the material distribution pipe and supported on the sintering grid section, a sealing groove is formed between the peripheral wall of the material distribution pipe and the cup hole, and the powder filling layer is filled in the sealing groove. The material distribution pipe can be pulled out after material distribution is completed, the powder filling layer can achieve automatic sealing between the mixture and the hole wall of the cup hole, the possibility that gaps exist between the mixture and the hole wall of the cup hole is effectively reduced, the edge effect caused by the gaps is reduced, the uniformity of the mixture in the sintering process is guaranteed, and the sintering quality is improved. The accuracy of parameters and results obtained by a sintering cup test is improved, and the technical problem that the accuracy of the results of the sintering cup test is not ideal enough is solved to a certain extent.
