Description

Technical Field

[0001] This invention relates to the field of water pressure testing technology, and in particular to a portable drip irrigation tape water pressure testing device. Background Technology

[0002] Traditional testing equipment is cumbersome to operate. Existing pressure testing devices are usually simple in structure, consisting only of a pressure gauge and a simple needle. When using them, operators often need to hold the drip irrigation tape with one hand and forcefully insert the needle with the other. Due to the lack of effective auxiliary gripping and force application structures, the insertion process is quite strenuous, and it is difficult to ensure that the needle is inserted vertically, which can easily lead to the needle bending or deviating.

[0003] Poor sealing performance and easy leakage: When a regular needle-type pressure gauge is inserted into the drip irrigation tape, there is a gap between the needle and the tear in the tape. Under the action of high-pressure water flow, water can easily spray out and leak from the gap. This not only wastes water resources, but also causes outside air and impurities to be drawn into the pipe under the negative pressure of the drip irrigation tape, affecting the accuracy of the measurement data. Summary of the Invention

[0004] The purpose of this invention is to provide a portable drip irrigation tape water pressure testing device, which greatly improves work efficiency and convenience. The device ingeniously integrates puncture, sealing and measurement functions into one unit. Through the simple operation logic of "press-insert-release", it realizes rapid detection of drip irrigation tape water pressure. The operator can complete all actions with one hand, which solves the problems of cumbersome operation, the need for two hands, and the difficulty of insertion of traditional equipment, and significantly improves the efficiency of farmland inspection.

[0005] To achieve the above objectives, the present invention provides a portable drip irrigation tape water pressure detection device, including a pressure gauge, an adapter connected to the bottom of the pressure gauge, a pin-type pressure conduit connected to the adapter, a lifting component and a leak-proof component sequentially mounted on the pin-type pressure conduit from top to bottom, the bottom of the lifting component being connected to the leak-proof component, the leak-proof component being driven by the lifting component to change its extension and retraction state, and the pressure gauge being equipped with a display screen and several operation buttons.

[0006] Preferably, the adapter includes a gauge sleeve, a connector body, and a connecting sleeve arranged sequentially from top to bottom. The gauge sleeve is connected to the bottom of the pressure gauge. The top and bottom of the connector body are connected to the gauge sleeve and the connecting sleeve, respectively. The connecting sleeve is connected to the top of the needle-type pressure conduit.

[0007] Preferably, the top of the needle-type pressure catheter is provided with a threaded portion that connects to the connecting sleeve, and the bottom of the needle-type pressure catheter is provided with a puncture needle.

[0008] Preferably, the needle-type pressure catheter is configured with a hollow interior and a tapered exterior, and the diameter of the catheter from the puncture needle to the threaded portion gradually increases.

[0009] Preferably, the lifting assembly includes an upper plate, a spring, and a lower plate sleeved on the needle-type pressure conduit. The upper and lower ends of the spring are respectively connected to the bottom of the upper plate and the top of the lower plate. Both the upper plate and the lower plate are provided with through holes, and the diameter of the spring is set to be larger than the diameter of the through holes.

[0010] Preferably, the leak-proof component includes a sliding sleeve and a fixed sleeve fitted onto the needle-type pressure conduit. The sliding sleeve is connected to the bottom of the lower plate. A plurality of support rods are evenly arranged on the circumference of the sliding sleeve. The other end of each support rod is connected to a hinge joint and a strut is connected through the hinge joint. One end of each strut is connected to the circumference of the fixed sleeve. Rubber leak-proof sleeves are provided on the opening surfaces formed by the support rods, and the rubber leak-proof sleeves are fixed to the struts.

[0011] Preferably, both the fixed sleeve and the sliding sleeve are configured as having a hollow interior and a conical exterior.

[0012] Preferably, the leak-proof component is configured as a detachable structure.

[0013] Preferably, the bottom of the lower plate is provided with anti-slip texture.

[0014] Therefore, the portable drip irrigation tape water pressure detection device of the present invention, which adopts the above-mentioned content, has the following beneficial effects compared with the prior art:

[0015] 1. This application is easy to operate and can be completed with one hand. The device adopts a linkage design between the lifting component and the leak-proof component. The operator only needs to hold the device with one hand and pull the lower plate upward with his fingers to move the sliding sleeve upward. Then, through the hinge linkage of the support rod and the strut, the leak-proof component can be retracted to facilitate insertion into the water pressure detection position of the drip irrigation tape. This design simplifies the pressure detection action to a one-handed pressing action, which greatly improves the efficiency of field operations.

[0016] 2. Superior sealing performance effectively solves the leakage problem. The leak-proof component adopts a mechanical linkage support structure. When the needle-type pressure conduit is inserted into the drip irrigation tape, the lower plate is released, and the spring returns to drive the support rod to open, so that the rubber leak-proof sleeve tightly fits the inner wall of the drip irrigation tape. This sealing method of tightening from the inside out is more reliable than the traditional external force pressing seal. It can effectively prevent high-pressure water from leaking from the puncture hole during the measurement process, ensuring the accuracy of the measurement and the dryness of the operation.

[0017] 3. Stable structure and good insertion guidance: The needle-type pressure catheter is designed with a "hollow inside and conical outside" structure, and the diameter gradually increases from the puncture needle tip to the threaded part. This variable diameter design ensures the sharpness of the top puncture while increasing the structural strength of the catheter root, making the catheter less prone to bending and deformation during puncture. At the same time, the conical structure plays a guiding role, making it easy for the leak-proof component to enter the drip irrigation tape smoothly.

[0018] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0026] Example

[0027] like Figures 1-4As shown, a portable drip irrigation tape water pressure testing device of the present invention includes a pressure gauge 1, an adapter 2 connected to the bottom of the pressure gauge 1, and a needle-type pressure conduit 3 connected to the adapter 2. A lifting component 4 and a leak-proof component 5 are sequentially mounted on the needle-type pressure conduit 3 from top to bottom. The bottom of the lifting component 4 is connected to the leak-proof component 5, and the leak-proof component 5 is moved by the lifting component 4 to change its extension / retraction state. The pressure gauge 1 is equipped with a display screen 6 and several operation buttons 7. The integrated design of the display screen 6 and operation buttons 7 makes the reading intuitive and the operation simple. The adapter 2 plays a transitional connecting role, ensuring the sealing and stability of the connection. The most crucial effect is that it enables one-handed operation. Through the linkage mechanism of the lifting component 4 driving the leak-proof component 5, the complex insertion and sealing actions are simplified into a single pressing action, greatly improving the convenience and efficiency of field operations.

[0028] The adapter includes a gauge sleeve 21, a connector 22, and a connecting sleeve 23 arranged sequentially from top to bottom. The gauge sleeve 21 is connected to the bottom of the pressure gauge 1. The top and bottom of the connector 22 are connected to the gauge sleeve 21 and the connecting sleeve 23, respectively. The connecting sleeve 23 is connected to the top of the needle-type pressure conduit 3. This segmented connection structure allows the pressure gauge 1, the adapter 2, and the pressure conduit to be disassembled independently, facilitating the separate carrying, cleaning, and maintenance of the equipment. When a component is damaged (such as a faulty pressure gauge 1 or a blocked conduit), it can be replaced individually without scrapping the entire machine, thus reducing maintenance costs.

[0029] The top of the needle-type pressure conduit 3 is provided with a threaded part 31 that connects to the connecting sleeve 23, and the bottom of the needle-type pressure conduit 3 is provided with a puncture needle 32. The threaded connection ensures the firmness of the connection between the conduit and the adapter 2, preventing the conduit from falling off and being left behind during the pulling process. The design of the puncture needle 32 ensures that it can easily pierce the wall of the drip irrigation tape, realize non-destructive testing of the pressure inside the tube, saves effort in operation and minimizes damage to the drip irrigation tape.

[0030] The needle-type pressure catheter 3 is configured to be hollow inside and tapered outside, and the diameter of the needle-type pressure catheter 3 gradually increases from the puncture needle 32 to the threaded part 31.

[0031] The lifting assembly 4 includes an upper plate 41, a spring 42, and a lower plate 43 fitted onto the needle-type pressure conduit 3. The upper and lower ends of the spring 42 are connected to the bottom of the upper plate 41 and the top of the lower plate 43, respectively. Both the upper plate 41 and the lower plate 43 are provided with through holes 44. The diameter of the spring 42 is set to be larger than the diameter of the through hole 44. The upper plate 41 and the lower plate 43 provide a force-bearing platform. With the elastic potential energy of the spring 42, the operator only needs to apply a small pressing force to overcome the resistance and lift the leak-proof assembly 5. The design that the diameter of the spring 42 is larger than the diameter of the through hole 44 ensures that the spring 42 always works between the upper plate 41 and the lower plate 43 and will not come out, thus ensuring the reliability and service life of the mechanical action.

[0032] Leak-proof component 5 includes a sliding sleeve 51 and a fixed sleeve 52 fitted onto the needle-type pressure conduit 3. The sliding sleeve 51 is connected to the bottom of the lower plate 43. A plurality of support rods 53 are evenly arranged on the circumference of the sliding sleeve 51, with one end of each support rod 53 connected to a hinge joint 54, and a strut 55 connected to the hinge joint 54. One end of the strut 55 is connected to the circumference of the fixed sleeve 52. Rubber leak-proof sleeves 56 are provided on the opening surfaces formed by the support rods 53 corresponding to the struts 55. 6 is fixed on the support rod 55; first, the sliding sleeve 51 follows the lower plate 43 upward to drive the support rod 55 to retract and puncture the drip irrigation tape. After the puncture is completed, the lower plate 43 is released and the sliding sleeve 51 moves downward to drive the support rod 55 to open, so that the rubber leak-proof sleeve 56 fits tightly against the inner wall of the drip irrigation tape, realizing an active seal "from the inside out", effectively blocking the puncture hole and preventing high-pressure water leakage; the design of the hinge joint 54 and the support rod 53 transforms the longitudinal linear motion into the lateral opening motion, and the action transmission is precise.

[0033] Both the fixed sleeve 52 and the sliding sleeve 51 are designed to be hollow inside and conical on the outside.

[0034] The leak-proof component 5 is designed as a detachable structure, which means that vulnerable parts such as the rubber leak-proof sleeve 56 and the support rod 55 can be replaced individually after long-term use and wear, without having to scrap the entire device, thus reducing the cost of use. In addition, the pressure gauge 1 and the adapter 2, as well as the adapter 2 and the conduit, are all designed to be connectable, which facilitates the separate carrying and maintenance of the components.

[0035] The bottom of the lower plate 43 is provided with anti-slip texture 45, which increases the friction of the finger contact surface, prevents slipping during pressing and lifting, and improves the accuracy and safety of operation.

[0036] In the specific implementation process, check whether the pressure gauge is normal and initialize the pressure gauge data. By pressing with your fingers, hook the lower plate up and squeeze the upper plate to drive the sliding sleeve to slide upward. At this time, the anti-leak component retracts to perform the piercing action of the drip irrigation tape. After the piercing is completed, release the lower plate and drive the sliding sleeve downward to drive the support rod to open, so that the rubber anti-leak sleeve tightly fits the inner wall of the drip irrigation tape, realizing active sealing from the inside out, effectively blocking the piercing hole on the drip irrigation tape, preventing high-pressure water leakage, and measuring a relatively accurate water pressure. After the measurement is completed, hook the lower plate up again to retract the anti-leak component, and then remove it from the drip irrigation tape.

[0037] Therefore, the present invention provides a portable drip irrigation tape water pressure testing device based on the above-mentioned content, which greatly improves the efficiency and convenience of operation. The device ingeniously integrates puncture, sealing and measurement functions into one unit. Through the simple operation logic of "press-insert-release", it realizes the rapid detection of drip irrigation tape water pressure. The operator can complete all actions with one hand, which solves the problems of cumbersome operation, the need for two-handed cooperation and the difficulty of insertion of traditional equipment, and significantly improves the efficiency of farmland inspection.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
