Description
Technical Field
[0001] The invention relates to the technical field related to drip irrigation pipe docking, and in particular to a water-leakage-proof pipe docking device. Background Art
[0002] Drip irrigation, as an efficient and water-saving irrigation method, is widely used in modern agriculture. By precisely delivering water to the roots of plants, the drip irrigation system reduces water waste and improves irrigation efficiency. However, pipe docking is a key link in the installation and maintenance of drip irrigation systems. Existing docking equipment is easily damaged during use, which in turn affects the sealing performance of the pipe joints.
[0003] In order to solve the above-mentioned defects, the existing technology (Announcement No. CN218104410U, Chinese patent announcement date 2022-12-23) discloses an irrigation pipe connection mechanism, wherein the pipe docking part includes a docking pipe, a pipe flange is provided on the outside of the docking pipe, and a flat sealing gasket is nested at one end of the docking pipe, and a curved sealing gasket is nested at the other end of the docking pipe. The auxiliary drip irrigation pipe is buckled on both sides of the main water supply pipe using pipe fixing parts, which can not only provide good protection for the connection parts and reduce damage to the connection parts, but also facilitate installation and disassembly and maintenance, which is beneficial to the drip irrigation laying of the pipeline and has stronger practicality. In the above-mentioned scheme, when the pipeline is docked through the connecting mechanism during use, the branch pipe is docked and fixed to the main pipe by extrusion and resistance, and only a sealing gasket of fixed shape is provided at the connection for sealing. For the tiny gaps and irregular surfaces at the pipe joints, the fit is not tight enough, which affects the sealing effect and is prone to water leakage. Summary of the Invention
[0004] The object of the present invention is to provide a water-leakage-proof pipe docking device to solve the problem of the existing pipe docking device proposed in the above-mentioned background technology. During use, when the pipes are docked through the connecting mechanism, the branch pipe is docked and fixed with the main pipe by means of squeezing and contacting. The connection is only provided with a sealing gasket of fixed shape for sealing. The gasket is not tightly fitted to the tiny gaps and irregular surfaces at the pipe joints, thereby affecting the sealing effect and easily causing water leakage.
[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a water-leakage-proof pipe docking device, comprising a drip irrigation main pipe, with docking joints provided on both sides of the drip irrigation main pipe, a drip irrigation branch pipe connected to the outside of the docking joint, a docking device connected between the docking joint and the branch pipe, the left and right ends of the docking device covering the outside of the docking joint and the branch pipe, sealing sleeves symmetrically provided on both sides of the docking device, the sealing sleeves being connected to the sealing grooves in a concave-convex manner, the sealing grooves being respectively opened on the opposite surfaces of the docking joint and the branch pipe, sealing bags being provided on the inner walls on both sides of the left and right sides of the docking device, the sealing bags being tightly fitted with the outer sides of the docking joint and the branch pipe.
[0006] Furthermore, the cross-section of the docking connector is set to a "T"-shaped structure, the middle part of the docking connector is set to be hollow, the flow area in the middle part of the docking connector is consistent with the flow area of the branch pipe of the docking joint, and the plug-in space at the left and right ends of the docking connector and the middle part form a stepped setting.
[0007] Furthermore, the top and bottom of the docking device are symmetrically rotatably connected with rotating rods, and the rotating rods are connected through the inner cavity, and the inner cavity is symmetrically opened on the inner side of the top and bottom of the docking device.
[0008] Furthermore, a thread is provided on the outer side of the rotating rod, a pressure plate is threadedly connected to the bottom of the rotating rod, and the pressure plate is slidably connected to the inner cavity. The inner cavity and the pressure plate are both configured as rectangular structures.
[0009] Furthermore, an air storage bag is symmetrically arranged at the bottom of the inner cavity, the pressure plate is in compression contact with the air storage bag, and the air storage bag is connected to the sealing bag through a connecting tube.
[0010] Furthermore, the air storage bag and the sealing bag form a sealing structure, and the sealing bag is configured as an annular structure.
[0011] Furthermore, a locking block is integrally installed at the end of the pressure plate, and the locking block is slidably connected to the inner walls of the left and right ends of the docking device, and the end of the locking block is engaged with the slot, and the slot is correspondingly opened on the outside of the docking head and the branch pipe.
[0012] Compared with the prior art, the present invention has the following beneficial effects: During use, when the pipes are connected, the sealing bag is squeezed and adaptively fills the tiny gaps and irregular surfaces at the pipe joints to form a tight fit and ensure the sealing effect. The sealing sleeve tightly wraps the pipe joint, further enhancing the reliability of the seal and reducing the risk of leakage. At the same time, the setting of the locking block and the slot can further improve the stability of the pipe joint.
[0013] 1. Furthermore, the butt joint and the branch pipe are respectively plugged into the two sides of the butt joint. At this time, the sealing grooves on the opposite surfaces of the butt joint and the branch pipe will be plugged into the sealing sleeves on both sides of the butt joint, thereby performing internal sealing.
[0014] 2. Furthermore, the rotating rod on the outside of the docking device is rotated. After the rotating rod is rotated, the pressure plate will be driven to move downward in the inner cavity, thereby squeezing the air storage bag. The gas in the air storage bag will be transported to the sealing bag. After the sealing bag expands, it will fill the gap between the docking device, the docking joint and the branch pipe, thereby performing a secondary sealing process, improving the sealing performance of the joint, and preventing water leakage.
[0015] 3. Furthermore, when the pressure plate moves, it will drive the locking block to move synchronously, and the locking block will extend and engage with the slot, thereby improving the stability of the connection between the docking device, the docking head and the branch pipe, and further improving the stability of the connection between the drip irrigation main pipe and the branch pipe.
