Description

Technical Field

[0001] The utility model relates to the technical field of drip irrigation tape production, in particular to a pressure testing device for drip irrigation tape production. Background Technique

[0002] Drip irrigation is a precise irrigation method. Using a low-pressure pipeline system, water is directly transported to the field, and then through water distributors such as drippers, orifices or drip irrigation tapes installed on the lateral pipes, the water is evenly and slowly dripped into the soil near the root zone of the crops drop by drop, so that the soil in the most developed area of the crop roots always maintains an appropriate humidity, and the water, fertilizer, air, heat and microbial activities in the soil are always in good condition, creating favorable conditions for high and stable yields of crops. During the production process of drip irrigation tapes, it is necessary to conduct pressure tests on them to avoid cracking and leaking during use due to the inability of the drip irrigation tapes to withstand water pressure, which affects drip irrigation work.

[0003] The drip irrigation tape pipe pressure testing device with the application number 202321986154.3 includes a base and a water tank. A cylinder is provided on the base, and a spiral fixing plate for placing the drip irrigation tape is installed on the outer side wall of the cylinder. The bottom of the water tank is provided with a water outlet pipe, and the top is provided with a water inlet pipe. A water pump communicated with the water outlet pipe is installed in the water tank. A pressure valve is installed on the water inlet pipe. The water tank is provided with a water inlet. The two ends of the drip irrigation tape are hermetically connected to the water outlet pipe and the water inlet pipe respectively through pipe clamps. For the drip irrigation tape pipe pressure testing device of this application, the drip irrigation tape can be spirally fixed on the outer wall of the cylinder along the spiral fixing plate, and the drip irrigation tape is evenly dispersed everywhere and will not stack. When injecting water into the drip irrigation tape through the water outlet pipe by the water pump to pressurize it, if there is a leak at a place where the side wall of the drip irrigation tape has weak compressive resistance, it is convenient to find the leakage position of the drip irrigation tape. At the same time, through the water inlet pipe and the water tank, it is convenient to recycle the water used for pressure testing and can be repeatedly tested and used.

[0004] However, in the disassembly and assembly process of this technical solution, it is necessary to rotate the cylinder, then fit the drip irrigation tape with the cylinder and then fasten and limit the drip irrigation tape through a limit buckle. Repeating the above operations several times can complete the disassembly and assembly operations, which is time-consuming and laborious; and when using liquid for pressure testing, if the holes leaking water on the drip irrigation tape are relatively small, then the overflowing water flow is also relatively small, resulting in it being very difficult for the staff to observe the leakage points, and the staff needs to walk around the cylinder to see whether there are leakage points on the whole drip irrigation tape, and the operation is cumbersome, time-consuming and laborious. Content of the Utility Model

[0005] Based on this, the purpose of the present utility model is to provide a pressure testing device for drip irrigation tape production to solve the technical problems mentioned in the above background technique.

[0006] To achieve the above object, the present utility model provides the following technical solution: A pressure testing device for drip irrigation tape production, including a base, on both sides of the top of the base are respectively provided with a placing cylinder and an air pump, and a hydraulic cylinder is installed inside the placing cylinder. The output end of the hydraulic cylinder is connected to a bottom plate, and a guide groove is opened on the top of the bottom plate. The top of the guide groove is connected to a chassis through a guide ring, and a top frame is connected to the outer surface of the chassis. One side of the chassis is connected to a drip irrigation tape joint. A rotary joint is installed on the top of the chassis, and an air supply pipe is connected between the rotary joint and the air pump.

[0007] By adopting the above technical solution, one end of the drip irrigation tape is connected to the drip irrigation tape joint, and then the other end of the drip irrigation tape is blocked by tying it with a wire or installing a plug. Then, the drip irrigation tape is wound by rotating the chassis. The friction and wear between the chassis and the bottom plate are reduced through the settings of the guide ring and the guide groove, and the chassis is prevented from falling off upward. After winding, the top and bottom of the drip irrigation tape are limited by the chassis and the top frame. After the chassis descends into the placing cylinder, the drip irrigation tape is limited around by the placing cylinder to prevent the drip irrigation tape from falling off; the hydraulic cylinder drives the bottom plate, the chassis, the top frame and the drip irrigation tape to descend, so that the drip irrigation tape enters the water. After the air pump is started, air is sent into the chassis through the air supply pipe and the rotary joint. Through the setting of the rotary joint, the air supply pipe is prevented from being twisted off when the chassis rotates and winds the drip irrigation tape. Then, the chassis sends air into the drip irrigation tape through the drip irrigation tape joint. At this time, the drip irrigation tape is inflated. When the drip irrigation tape cannot withstand the pressure and ruptures or has holes, the gas in the drip irrigation tape leaks out through the cracks or holes. Since the density of the gas is lower than that of water, the leaked gas will form bubbles and rise. The top frame is welded by multiple round rods, and the structure is hollow and will not affect the rising of the bubbles. Then, the staff can find the leak point of the drip irrigation tape by observing the bubbles from the top of the placing cylinder, which is convenient for observation.

[0008] Further, the placing cylinder is filled with clear water.

[0009] By adopting the above technical solution, when the drip irrigation tape cannot withstand the pressure and ruptures or has holes, the gas in the drip irrigation tape leaks out through the cracks or holes. Since the density of the gas is lower than that of water, the leaked gas will form bubbles and rise. The staff can find the leak point of the drip irrigation tape by observing the bubbles from the top of the placing cylinder, which is convenient for observation.

[0010] Further, the chassis is rotatably connected to the bottom plate through the guide ring and the guide groove.

[0011] By adopting the above technical solution, the staff rotates the chassis to wind the drip irrigation tape, and at the same time, the friction and wear between the chassis and the bottom plate are reduced through the settings of the guide ring and the guide groove.

[0012] Further, the cross-sections of the guide ring and the guide groove are both in the shape of a "convex".

[0013] By adopting the above technical solution, since the cross-sections of the guide ring and the guide groove are both convex-shaped, the chassis is prevented from falling off upward.

[0014] Furthermore, both the chassis and the bottom plate are slidably connected to the placement cylinder.

[0015] By adopting the above technical solution, after the hydraulic cylinder is started, the output end drives the abutting plate, the chassis, the top frame and the drip irrigation belt to descend, so that the drip irrigation belt enters the water in the placement cylinder.

[0016] Furthermore, the top frame is fixedly welded by a plurality of metal round rods, and the top frame is fixedly connected to the chassis.

[0017] By adopting the above technical solution, the drip irrigation belt is wound up by the chassis, and after winding, the top and bottom of the drip irrigation belt are limited by the chassis and the top frame.

[0018] Furthermore, the air supply pipe is a flexible pipe.

[0019] By adopting the above technical solution, since the air supply pipe is a flexible pipe, when the hydraulic cylinder drives the chassis together with the rotary joint to move up and down, the air supply pipe will not be twisted and broken.

[0020] Furthermore, a telescopic folding sleeve is connected between the bottom plate and the base, and the hydraulic cylinder is located inside the telescopic folding sleeve. The telescopic folding sleeve is made of silica gel material.

[0021] By adopting the above technical solution, the telescopic folding sleeve can adapt to the lifting of the bottom plate, and the hydraulic cylinder is protected by the telescopic folding sleeve to prevent water from contacting the hydraulic cylinder.

[0022] In summary, the main beneficial effects of the present utility model are as follows:

[0023] 1. By setting the drip irrigation belt joint, the placement cylinder, the chassis, the top frame, the guide ring, the guide groove and the bottom plate, one end of the drip irrigation belt is connected to the drip irrigation belt joint, and then the other end of the drip irrigation belt is blocked by tying it with a wire or installing a plug. Then, the drip irrigation belt is wound up by rotating the chassis. The friction and wear between the chassis and the bottom plate are reduced through the setting of the guide ring and the guide groove, and the chassis is prevented from falling off upward. After winding, the top and bottom of the drip irrigation belt are limited by the chassis and the top frame. After the chassis descends into the placement cylinder later, the drip irrigation belt is limited around by the placement cylinder to prevent the drip irrigation belt from falling off; the disassembly and assembly operations are simple and convenient, and no additional limiting is required;

[0024] 2. Through the arrangement of the placement cylinder, air pump, rotary joint and hydraulic cylinder, the pressing plate, chassis, top frame and drip irrigation tape are driven to descend by the hydraulic cylinder, so that the drip irrigation tape enters the water. After the air pump is started, air is sent into the chassis through the air delivery pipe and the rotary joint. Through the arrangement of the rotary joint, it is avoided that the air delivery pipe is twisted off when the chassis rotates and winds up the drip irrigation tape. Then, the chassis sends air into the drip irrigation tape through the drip irrigation tape joint. At this time, the drip irrigation tape is inflated. When the drip irrigation tape cannot withstand the pressure and bursts or has holes, the gas in the drip irrigation tape leaks out through the cracks or holes. Since the density of the gas is lower than that of water, the leaked gas will form bubbles and rise. The top frame is welded by multiple round rods, and the hollow structure will not affect the rising of the bubbles. Then, the staff can find the leak point of the drip irrigation tape by observing the bubbles from the top of the placement cylinder, which is convenient for observation; it is convenient to check the leak point, and there is no need for the staff to walk around the device to watch.

[0031] Next, the embodiments of the present utility model will be described according to the overall structure of the present utility model.

[0032] Embodiment 1:

One side of the top of the base 1 is connected with a placement cylinder 2, and the placement cylinder 2 is filled with clear water. When the drip irrigation tape cannot withstand the pressure and ruptures or has holes, the gas in the drip irrigation tape leaks out through the cracks or holes. Since the density of the gas is lower than that of water, the leaked gas will form bubbles and rise, which is convenient for viewing. A hydraulic cylinder 9 is installed inside the placement cylinder 2. The output end of the hydraulic cylinder 9 is connected with a bottom plate 10. Both the chassis 7 and the bottom plate 10 are slidably connected to the placement cylinder 2. After the hydraulic cylinder 9 is started, the output end drives the pressing plate, the chassis 7, the top frame 8 and the drip irrigation tape to descend, so that the drip irrigation tape enters the water in the placement cylinder 2. A guide groove 12 is opened at the top of the bottom plate 10, and the top of the guide groove 12 is connected with the chassis 7 through a guide ring 11. The cross-sections of both the guide ring 11 and the guide groove 12 are in the shape of a "convex". The chassis 7 is rotationally connected with the bottom plate 10 through the guide ring 11 and the guide groove 12, and the staff rotates the chassis 7 to wind up the drip irrigation tape. The outer surface of the chassis 7 is connected with a top frame 8. The top frame 8 is welded and fixed by a plurality of metal round rods. The top frame 8 is fixedly connected with the chassis 7. After winding up, the top and bottom of the drip irrigation tape are limited by the chassis 7 and the top frame 8. One side of the chassis 7 is connected with a drip irrigation tape joint 6, and one end of the drip irrigation tape is connected to the drip irrigation tape joint 6, which is convenient for winding up the drip irrigation tape.

[0034] Refer to Figure 1 and Figure 2 , in the above-mentioned embodiment, an air pump 3 is installed on the other side of the top of the base 1. After the air pump 3 is started, air is sent into the chassis 7 through an air delivery pipe 4 and a rotary joint 5; a rotary joint 5 is installed on the top of the chassis 7. Through the setting of the rotary joint 5, it is avoided that the air delivery pipe 4 is twisted off when the chassis 7 rotates to wind up the drip irrigation tape; a flexible air delivery pipe 4 is connected between the rotary joint 5 and the air pump 3. The flexible air delivery pipe 4 can avoid the air delivery pipe 4 being twisted off when the chassis 7 moves up and down.

[0035] Embodiment Two:

[0036] On the basis of the above-mentioned Embodiment One, to avoid the hydraulic cylinder 9 contacting with water; the following settings are now made.

[0037] Refer to Figure 2 , in the above-mentioned embodiment, a telescopic folding sleeve 13 is connected between the bottom plate 10 and the base 1. The hydraulic cylinder 9 is located inside the telescopic folding sleeve 13. The telescopic folding sleeve 13 is made of silica gel material. The hydraulic cylinder 9 is protected by the telescopic folding sleeve 13 to avoid water contacting the hydraulic cylinder 9.

[0038] The implementation principle of the present utility model is as follows: First, the staff connects one end of the drip irrigation tape to the drip irrigation tape joint 6, and then the staff blocks the other end of the drip irrigation tape by tying it tightly with wire or installing a plug. Then, the staff rotates the chassis 7 to wind up the drip irrigation tape. At this time, due to the setting of the rotary joint 5, it is avoided that the air supply pipe 4 is twisted off when the chassis 7 rotates to wind up the drip irrigation tape. And due to the setting of the guide ring 11 and the guide groove 12, the friction and wear between the chassis 7 and the bottom plate 10 are reduced, and it is avoided that the chassis 7 falls off upward. After winding up, the top and bottom of the drip irrigation tape are limited by the chassis 7 and the top frame 8. After winding up the drip irrigation tape, the staff starts the hydraulic cylinder 9 and the air pump 3. At the same time, the hydraulic cylinder 9 is protected by the telescopic folding sleeve 13 to avoid water contacting the hydraulic cylinder 9. After the hydraulic cylinder 9 is started, the output end drives the pressing plate, the chassis 7, the top frame 8 and the drip irrigation tape to descend, so that the drip irrigation tape enters the water in the placing cylinder 2. And the drip irrigation tape is limited around by the placing cylinder 2 to avoid the drip irrigation tape falling off. After the air pump 3 is started, air is sent into the chassis 7 through the air supply pipe 4 and the rotary joint 5. Then, the chassis 7 sends air into the drip irrigation tape through the drip irrigation tape joint 6. At this time, the drip irrigation tape is inflated. When the drip irrigation tape cannot bear the pressure and bursts or has holes, the gas in the drip irrigation tape leaks out through the cracks or holes. Since the density of the gas is lower than that of water, the leaked gas will form bubbles and rise. The top frame 8 is formed by welding multiple round rods, and the structure is hollow and will not affect the rising of the bubbles. Then, the staff can find the leak point of the drip irrigation tape by observing the bubbles from the top of the placing cylinder 2, which is convenient for observation;

[0039] After the test is completed, the hydraulic cylinder 9 starts to drive the pressing plate, the chassis 7, the top frame 8 and the drip irrigation tape to rise. Then, the staff can pull the drip irrigation tape to make the chassis 7 reverse to release the drip irrigation tape. Finally, separating the drip irrigation tape from the drip irrigation tape joint 6 can complete the work.
