6results about How to "Will not cause accumulation" patented technology

This utility model discloses an explosion-proof junction box with automatic retractable cable. It features a built-in winding device for cable extension and retraction. During adjustment, the cable is simply pulled out for connection, and automatically retracts after resetting, preventing redundant cable accumulation. It replaces the traditional rigid "pipeline-equipment" connection with a flexible "pipeline-telescopic junction box-equipment" connection, creating a buffer zone for debugging. This significantly reduces wiring and disassembly time, improving debugging efficiency. The cable can be reused repeatedly, resulting in significant economic benefits. The limit buckle design restricts excessive cable extension, and the junction box is detachable and reusable within a sealed cavity, enabling dynamic cable extension and retraction. This overcomes the technical bias of traditional explosion-proof equipment with immovable wiring, making it suitable for large-scale industrial use and promotion.

This invention provides a leak-proof photovoltaic power generation array and its installation method, including mounting legs, connecting hinges, horizontal support rods, vertical support rods, movable connecting components, support frames, photovoltaic panels, vertical sealing seats, vertical sealing mechanisms, secondary water receiving channels, drainage channels, and connecting water pipes. Each row of photovoltaic panels in this invention has a secondary water receiving channel at its bottom, and all secondary water receiving channels are connected to the drainage channel. Since rainwater from each row of photovoltaic panels is collected and discharged through the corresponding secondary water receiving channel, the rainwater flow rate on the surface of each row of photovoltaic panels is the same during rain, preventing rainwater accumulation. The gaps between adjacent photovoltaic panels in the same row are sealed by the vertical sealing mechanism, enhancing the sealing performance and ensuring that rainwater can only flow downwards into the secondary water receiving channels. Because the movable connecting components are detachably fixed to the horizontal support rods, the positions of the vertical support rods and vertical sealing seats can be adjusted according to the width of the photovoltaic panels.

This anti-clogging device belongs to the technical field of submersible pump auxiliary equipment, specifically an anti-clogging device for the inlet of an automatically coupled submersible pump. Its features include a support frame, a filter screen, a connecting pipe, a clamp, connecting bolts, and nuts. The support frame is a cage-like structure with a circular opening at the top. The connecting pipe is welded to the opening, and the connecting pipe connects to the submersible pump inlet through the clamp, connecting bolts, and nuts. A filter screen covers the outside of the support frame. This anti-clogging device for the inlet of an automatically coupled submersible pump can prevent large particles and entangled materials from entering the pump body and causing pump malfunctions without affecting pump performance, thus improving pump lifespan and reducing maintenance frequency.

The embodiment of the application discloses a printer main body and a printer. A first containing cavity and a first paper outlet channel are formed in the printer main body. A first paper outlet of the first paper outlet channel is arranged on a first surface of the printer main body. The first surface is parallel to the depth direction of the first containing cavity. The printer main body comprises a transmission shaft. The transmission shaft and the first paper outlet extend along the depth direction of the first containing cavity. A reel of a carbon tape roll in a consumable box is sleeved on the transmission shaft. The consumable box and the printer main body can be designed to be flat, and the volume of the consumable box and the printer main body is compressed. The printer can be placed on a desktop for use or held for use. When the printer is used, the first surface can be located on the side, and the first paper outlet is located on the side. When the first paper outlet outputs label paper, the label paper is output to the side of the printer, and the side of the printer is not constrained, so that paper accumulation is avoided, and smooth paper output is facilitated.

This utility model discloses a material grinding device for melamine particle production, relating to the field of melamine particle production technology. It includes a housing, with a first motor fixedly connected to the top of the housing. A grinding mechanism is fixedly connected to the output end of the first motor. A feed pipe is connected through one side of the housing, and a roller pressing device is fixedly connected to another side of the housing. In this utility model, melamine material enters the discharge port from a groove and then falls into the middle section between the grinding disc and the upper grinding mold. After the top device rotates, the melamine is ground internally. Simultaneously, grinding strips at the bottom further accelerate the grinding process, narrowing the pressure gap and making the grinding finer. This allows the device to handle the melamine more effectively, reducing the powder's volume and allowing it to exit from the groove. Larger particles continue to be ground internally. Driven by a second motor, the rollers push the melamine particles outwards, facilitating material discharge and preventing material accumulation inside the device.
