Description

Technical Field

[0001] This utility model belongs to the field of farmland water conservancy technology, specifically relating to a farmland water utilization pipeline connection device. Background Technology

[0002] The background technology of farmland water utilization pipeline connection devices mainly involves the limitations of pipeline connections in traditional irrigation systems. These systems often use flanges, threads, or adhesive bonding, which result in problems such as complex installation, poor sealing, and susceptibility to corrosion and leakage. They are particularly prone to loosening when there are large temperature differences or geological changes. With the promotion of water-saving irrigation technologies, the demand for quick disassembly and assembly, pressure resistance, and leak prevention is becoming increasingly prominent. The widespread use of plastic and composite material pipes also requires connection devices to be both lightweight and high-strength.

[0003] Chinese patent publication number CN220647130U discloses a connection device for farmland water utilization pipelines, including a first connecting pipe and a second connecting pipe. The inner surface of the left end of the first connecting pipe has a through hole, and the inner surface of the right end of the second connecting pipe has a connecting threaded hole. A positioning slider is fixedly connected to the right end of the outer surface of the second connecting pipe, and a connecting sleeve is fitted onto the left end of the outer surface of the first connecting pipe. This patent solves the problem of the inconvenience of connecting and disassembling common farmland water conservancy pipelines by using the functions of a connecting ring, sealing ring, sealing groove, connecting screw, positioning groove, connecting sleeve, positioning slider, external toothed ring, driving gear, and driving motor. This is because most common farmland water conservancy pipelines are connected by bonding or welding, which requires other auxiliary tools and cannot be disassembled and transported, causing many inconveniences for users.

[0004] However, the current device has the following problems: the pipes are prone to corrosion, which leads to decreased sealing performance, frequent leaks, increased maintenance costs, reduced water delivery efficiency, water pollution, crop growth, and shortened system lifespan. Therefore, we propose a farmland water utilization pipe connection device. Utility Model Content

[0005] The purpose of this utility model is to provide a connection device for agricultural water utilization pipelines, which can solve the problems in related technologies where the pipelines of such devices are prone to corrosion, leading to decreased sealing performance, frequent leaks, increased maintenance costs, reduced water conveyance efficiency, water pollution, impact on crop growth, and shortened system lifespan.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A farmland water utilization pipeline connection device includes a first connecting pipe. A fixing plate is fixedly connected to the circumferential surface of the first connecting pipe. A threaded rod is rotatably connected to the side of the fixing plate. The threaded rod is driven by a motor, which is fixedly connected to the side of the fixing plate. A threaded sleeve is threadedly connected to the threaded surface of the threaded rod. A second connecting pipe is fixedly connected to the inner wall of the threaded sleeve. An anti-corrosion device is provided on the circumferential surface of the first connecting pipe to prevent corrosion. The anti-corrosion device includes an annular groove. The inner wall of the annular groove is fixedly connected to the circumferential surface of the first connecting pipe. A slider is slidably connected to the outer wall of the annular groove.

[0009] The corrosion protection device also includes a spray plate fixedly connected to the side of the slider, and a folded liquid storage bladder is fixedly connected to the side of the slider.

[0010] The circumferential surface of the coating roller is in contact with the spray plate, and the side of the folded liquid reservoir away from the slider is in contact with the connecting plate.

[0011] The side of the sprayed plate is provided with a pretreatment device for a cleaning connecting pipe. The pretreatment device includes a groove, which is opened on the side of the sprayed plate. A support rod is fixedly connected to the inner wall of the groove. An arc-shaped plate is slidably connected to the circumferential surface of the support rod. A spring is provided between the side of the arc-shaped plate and the inner wall of the groove.

The scraper is in contact with the circumferential surface of the first connecting pipe and the scraper is in contact with the circumferential surface of the second connecting pipe.

[0014] The technical effects achieved by this utility model are as follows:

[0015] This invention, through the setting of an anti-corrosion device, enables the cooperation of annular groove, slider, pin, fixing rod, brush roller, spray plate, and folded liquid storage tank.

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] like Figures 1-5 As shown, a farmland water utilization pipeline connection device includes a first connecting pipe 1. A fixing plate 2 is fixedly connected to the circumferential surface of the first connecting pipe 1. A threaded rod 3 is rotatably connected to the side of the fixing plate 2. The threaded rod 3 is driven by a motor, which is fixedly connected to the side of the fixing plate 2. The motor is electrically connected to an external controller. A threaded sleeve 4 is threadedly connected to the threaded surface of the threaded rod 3. A second connecting pipe 5 is fixedly connected to the inner wall of the threaded sleeve 4. The circumferential surface of the first connecting pipe 1 is provided with anti-corrosion material to prevent corrosion of the connecting pipe. Device 7, the corrosion protection device 7 includes an annular groove 71, the inner wall of the annular groove 71 is fixedly connected to the circumferential surface of the first connecting pipe 1, a slider 72 is slidably connected to the outer wall of the annular groove 71, a pin 73 is fixedly connected to the inner wall of the slider 72, a fixing rod 74 is rotatably connected to the side of the slider 72, a brush roller 75 is fixedly connected to the circumferential surface of the fixing rod 74, a sealing ring 6 is provided between the first connecting pipe 1 and the second connecting pipe 5, and sliding rods 9 are fixedly connected to the sides of multiple fixing plates 2, and the circumferential surfaces of the multiple sliding rods 9 are slidably connected to... The device includes sliding sleeves 10, the inner walls of which are fixedly connected to the circumferential surface of the second connecting pipe 5. Connecting plates 11 are fixedly connected to the sides of each sliding sleeve 10, with two connecting plates 11 fixedly connected to the sides of the threaded sleeve 4. The anti-corrosion device 7 also includes a spraying plate 76 fixedly connected to the side of a slider 72. A folded liquid storage bladder 77 is fixedly connected to the side of the slider 72. The folded liquid storage bladder 77 and the spraying plate 76 are connected via a straight pipe. The circumferential surface of the coating roller 75 is in contact with the spraying plate 76. The side of the folded reservoir 77 away from the slider 72 contacts the connecting plate 11. The rotation of the motor output shaft corresponding to the threaded rod 3 drives the rotation of the threaded rod 3. The rotation of the threaded rod 3 drives the movement of the threaded sleeve 4. The movement of the threaded sleeve 4 drives the movement of the second connecting pipe 5, realizing the connection between the threaded rod 3 and the threaded sleeve 4, and realizing the connection and installation of the first connecting pipe 1 and the second connecting pipe 5. When disassembly is required, the drive motor drives the threaded rod 3 to rotate in the opposite direction, so that the threaded sleeve 4 is disengaged and the first connecting pipe 1 and the second connecting pipe 5 are disassembled.

[0026] According to the above structure, the movement of the threaded sleeve 4 drives the movement of the connecting plate 11. The movement of the connecting plate 11 squeezes the folded liquid storage bladder 77, causing the anti-corrosion coating in the folded liquid storage bladder 77 to be transported through the straight pipe to the spraying plate 76 for spraying. The anti-corrosion coating sprayed by the spraying plate 76 is sprayed onto the coating roller 75 and slides along the outer wall of the annular groove 71. The slider 72 drives the movement of the fixed rod 74, and the movement of the fixed rod 74 drives the movement of the coating roller 75. The coating roller 75 applies the anti-corrosion coating to the circumferential surface of the first connecting pipe 1 and the second connecting pipe 5, isolating moisture, oxygen and chemicals, delaying corrosion, extending the life of the pipe, reducing the risk of leakage, improving water conveyance efficiency, reducing maintenance costs, and ensuring the stable operation of the farmland irrigation system.

[0027] like Figures 1-5 As shown, a pretreatment device 8 for cleaning connecting pipes is provided on the side of the spray plate 76. The pretreatment device 8 includes a groove 81, which is opened on the side of the spray plate 76. A support rod 82 is fixedly connected to the inner wall of the groove 81. An arc plate 83 is slidably connected to the circumferential surface of the support rod 82. A spring 84 is provided between the side of the arc plate 83 and the inner wall of the groove 81. A scraper 85 is fixedly connected to the side of the arc plate 83. A support plate 86 is fixedly connected to the circumferential surface of the second connecting pipe 5. A semi-circular block is fixed to the side of the scraper 85. Several protrusions are fixed to the side of the support plate 86. The circular surface of the protrusions of the support plate 86 is located on the movement trajectory of the circular surface of the semi-circular block of the scraper 85. A gap is left between the inner wall of the arc plate 83 and the circumferential surface of the coating roller 75. The scraper 85 is in contact with the circumferential surface of the first connecting pipe 1 and the circumferential surface of the second connecting pipe 5.

[0028] According to the above structure, the movement of slider 72 drives the movement of spray plate 76, the movement of spray plate 76 drives the movement of support rod 82, the movement of support rod 82 drives the movement of arc plate 83, and the movement of arc plate 83 drives the movement of scraper 85. When the semicircular block of scraper 85 rotates to the position of protrusion of support plate 86, the circular surface of protrusion of support plate 86 pushes the circular surface of semicircular block of scraper 85, driving scraper 85 to move. When the circular surface of protrusion of support plate 86 no longer pushes the semicircular block of scraper 85, arc plate 83 resets under the elastic force of corresponding spring 84. The movement of arc plate 83 drives scraper 85 to reset and move. The rotation and reciprocating movement of scraper 85 scrapes away impurities adhering to the circumferential surface of first connecting pipe 1 and second connecting pipe 5, preventing the coating roller 75 from failing to completely apply anti-corrosion coating to the circumferential surface of first connecting pipe 1 and second connecting pipe 5.

[0029] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
