Description

Technical Field

[0001] The utility model relates to the technical field of pipeline liquid leakage detection, and more specifically, to an intelligent liquid leakage detector. Background Art

[0002] Performing liquid leakage detection on the joints of pipelines is an important measure to ensure safety, protect the environment and reduce economic losses. Early detection and repair of leaks can effectively reduce the waste of liquid resources, which not only helps to ensure production safety and environmental protection, but also is an important guarantee for the sustainable development of enterprises.

[0003] In the prior art, when detecting the joints of pipelines, a liquid leakage detector is mostly used to cover the pipeline inside, and then a sealing cavity is formed by sealing with a sealing rubber strip. Thus, the air pressure in the formed sealing cavity is detected by a pressure sensor, and the sensor detects and judges whether the pipeline leaks. However, when on-site workers conduct inspections, they cannot timely and intuitively understand the leakage condition of the pipeline, which will have a certain impact on the timeliness of pipeline maintenance. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, adapt to the actual needs, and provide an intelligent liquid leakage detector to solve the problem in the prior art that on-site workers cannot timely and intuitively understand the leakage condition of the pipeline during inspections, which will have a certain impact on the timeliness of pipeline maintenance.

[0005] To solve the above technical problems, the utility model provides the following technical solution: An intelligent liquid leakage detector includes a pair of outer shells that cooperate with each other to cover the pipeline joint and an air pump. Sealing strips are arranged on the end faces of the outer shells. A plurality of fixing plates are arranged on the outer walls of the outer shells, and bolts are arranged to penetrate through the fixing plates on the outer walls. A pressure sensor is arranged inside the outer shells. The air suction port of the air pump is communicated with the inside of the outer shells. A detection mechanism for detecting the air pressure inside the outer shells is arranged inside the outer shells.

[0006] The detection mechanism includes a pair of receiving tubes, which are respectively arranged inside the outer shells. One end of each receiving tube penetrates through the inner wall of the outer shell to the outside. A spring is fixedly connected to the inner wall of the bottom of the receiving tube. A bearing member is fixedly connected to the top of the spring. A sealing ring is fixedly connected to the outer wall of the bearing member, and the outer wall of the sealing ring is in sealing fit with the inner wall of the receiving tube. An indicating rod is fixedly connected to the top of the bearing member. An air hole communicating with the inside of the receiving tube is opened at the bottom of the receiving tube.

[0007] Preferably, a connecting rod is hinged to the outer wall of the storage tube through a torsion spring. One end of the connecting rod is fixedly connected with a sealing piece. The top of the sealing piece abuts against the bottom of the storage tube and covers and seals the air hole. The other end of the connecting rod is fixedly connected with a floating block.

[0008] Preferably, multiple outer walls of the indicating rod extend outward uniformly to form multiple spherical structures on the outer wall of the indicating rod after the extension.

[0009] Preferably, the spherical structures formed by the indicating rod are one or a combination of more of red, yellow, and green.

[0010] Preferably, the bottom of the outer shell is inclined, and the bottom of the inclined part is used to guide the water flow to converge at the bottom of the storage tube.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. By providing an outer shell, an air pump, a sealing strip, a fixing plate, bolts, a barometric pressure sensor, and a detection mechanism, the present utility model can intelligently detect the air pressure inside the outer shell through the sensor, so as to judge the pipeline leakage condition. When the pipeline leaks, the indicating rod will move out of the storage tube, and the on-site staff can observe the indicating rod, so as to judge the pipeline leakage situation in a timely and intuitive manner and can repair the pipeline in time.

[0013] 2. In the present utility model, to prevent the indicating rod from being mis-extended out of the storage tube due to the gas leakage of the outer shell, resulting in the staff's misjudgment and affecting the work efficiency when repairing the pipeline, a sealing piece is provided to seal the air hole, so that the gas inside the outer shell cannot enter the storage tube. Only when the pipeline leaks, the water flow pushes the floating block, so that the floating block drives the sealing piece to twist through the connecting rod, so that the sealing piece no longer seals the air hole, and at this time the indicating rod will extend out.

[0014] 3. In the present utility model, the spherical structures formed by the multiple extensions of the indicating rod make it more intuitive and clear for the staff to observe the extended state of the indicating rod, so as to facilitate the staff to judge the pipeline leakage condition.

[0021] As Figures 1 to 4 shown, the present utility model relates to an intelligent liquid leakage detector, which includes a pair of outer shells 1 that cooperate with each other to cover the pipeline connection and an air pump 2. Sealing strips 3 are arranged on the end faces of the outer shells 1. A plurality of fixed plates 4 are arranged on the outer walls of the outer shells 1. Bolts 5 that penetrate the fixed plates 4 are arranged on the outer walls of the fixed plates 4. An air pressure sensor 6 is arranged inside the outer shells 1. The air extraction port of the air pump 2 is communicated with the inside of the outer shells 1. A detection mechanism for detecting the air pressure inside the outer shells 1 is arranged inside the outer shells 1;

[0022] The detection mechanism includes a pair of storage tubes 7, which are respectively arranged inside the outer shells 1. One end of each storage tube 7 penetrates the inner wall of the outer shell 1 to the outside. A spring 8 is fixedly connected to the bottom inner wall of the storage tube 7. The top of the spring 8 is fixedly connected to a bearing member 9. A sealing ring 10 is fixedly connected to the outer wall of the bearing member 9. The outer wall of the sealing ring 10 is in sealing fit with the inner wall of the storage tube 7. An indicator rod 11 is fixedly connected to the top of the bearing member 9. An air hole 12 communicated with the inside of the storage tube 7 is opened at the bottom of the storage tube 7;

[0023] Specifically, the corresponding fixed plates 4 are connected by the bolts 5 on the fixed plates 4, so that the fixed plates 4 fix the outer shells 1, so that the outer shells 1 sandwich the pipeline inside, and are sealed by the sealing strips 3. Subsequently, the air inside the outer shells 1 is extracted by the air pump 2, so that a negative pressure is generated inside the outer shells 1. During this process, due to the negative pressure inside the outer shells 1, the air inside the storage tubes 7 will also enter the inside of the outer shells 1, so that the bearing members 9 and the sealing strips 3 inside the storage tubes 7 move downward under the action of air pressure, and the bearing members 9 will squeeze the springs 8;

[0024] When the pipeline leaks, the leaked water will enter the inside of the outer shells 1. As the water inside the outer shells 1 increases, the air pressure inside the outer shells 1 will change, and the air pressure sensor 6 detects this change, so as to judge the water leakage situation of the pipeline and transmit the signal to the staff;

[0025] When the on-site staff conducts inspections, it is inconvenient to receive the signals sent by the medium-pressure sensor 6 in a timely manner. The on-site staff can determine whether there is a leak in the pipeline by observing whether the indicator rod 11 extends out of the receiving pipe 7. The principle is that when the pipeline leaks, the water in the pipeline will enter the housing 1, causing a change in the air pressure inside the housing 1. Since the receiving pipe 7 is connected to the housing 1 through the air hole 12, the air pressure inside the receiving pipe 7 will also change at this time, causing the spring 8 to push the carrier 9 upward under its own elastic force, and the carrier 9 pushes the indicator rod 11 upward to extend out of the receiving pipe 7.

[0026] Furthermore, one end of a connecting rod 13 is hinged to the outer wall of the receiving pipe 7 through a torsion spring. One end of the connecting rod 13 is fixedly connected with a sealing piece 14. The top of the sealing piece 14 is attached to the bottom of the receiving pipe 7 and covers and seals the air hole 12. The other end of the connecting rod 13 is fixedly connected with a floating block 15.

[0027] Specifically, to prevent the indicator rod 11 from accidentally extending out of the receiving pipe 7 due to gas leakage from the housing 1, which may lead to misjudgment by the staff and affect the work efficiency during pipeline maintenance, the air hole 12 is sealed by setting the sealing piece 14, so that the gas inside the housing 1 cannot enter the receiving pipe 7. Only when the pipeline leaks, the water flow pushes the floating block 15, causing the floating block 15 to drive the sealing piece 14 to twist through the connecting rod 13, so that the sealing piece 14 no longer seals the air hole 12, and at this time the indicator rod 11 will extend.

[0028] Furthermore, multiple outer walls of the indicator rod 11 extend uniformly outward to form multiple spherical structures on the outer wall of the indicator rod 11.

[0029] Specifically, the spherical structures formed by multiple extensions of the indicator rod 11 make it more intuitive and clear for the staff to observe the extended state of the indicator rod 11, thus facilitating the staff to judge the leakage condition of the pipeline.

[0030] Furthermore, the spherical structures formed by the indicator rod 11 are one or more combinations of red, yellow, and green.

[0031] Specifically, the spherical structures formed by the indicator rod 11 adopt one or more combinations of prominent red, yellow, and green, so as to facilitate the on-site staff to more intuitively observe the extended state of the indicator rod 11.

[0032] Furthermore, the bottom of the housing 1 is inclined, and the bottom of the inclined part is used to guide the water flow to converge at the bottom of the receiving pipe 7.

[0033] Specifically, the bottom of the inclined part of the housing 1 guides the water flow to converge at the bottom of the receiving pipe 7, making the speed at which the indicator rod 11 extends faster and increasing the time for the on-site staff to repair the pipeline.

[0034] Working principle: This embodiment provides an intelligent liquid leakage detector. When in use, the corresponding fixing plates 4 are connected through the bolts 5 on the fixing plates 4, so that the fixing plates 4 fix the outer shell 1, and the outer shell 1 clamps the pipeline inside and is sealed by the sealing strip 3. Subsequently, the air pump 2 is used to extract the gas inside the outer shell 1, so that a negative pressure is generated inside the outer shell 1. During this process, due to the negative pressure inside the outer shell 1, the gas inside the receiving pipe 7 will also enter the inside of the outer shell 1, so that the carrier 9 inside the receiving pipe 7 and the sealing strip 3 move downward under the action of air pressure, and the carrier 9 will squeeze the spring 8;

[0035] When the pipeline leaks, the leaked water will enter the inside of the outer shell 1. As the water in the outer shell 1 increases, the air pressure inside the outer shell 1 will change, and the air pressure sensor 6 detects this change to judge the water leakage situation of the pipeline and transmits the signal to the staff;

[0036] When the on-site staff conducts inspections, it is inconvenient to receive the signal sent by the air pressure sensor 6 in time. The on-site staff can judge whether there is a leak in the pipeline by observing whether the indicating rod 11 extends out of the receiving pipe 7. The principle is that when the pipeline leaks, the water in the pipeline will enter the outer shell 1, causing the air pressure inside the outer shell 1 to change. The receiving pipe 7 and the outer shell 1 are connected through the air holes 12. At this time, the air pressure inside the receiving pipe 7 will also change, causing the spring 8 to push the carrier 9 upward under its own elastic force, and the carrier 9 pushes the indicating rod 11 upward to extend out of the receiving pipe 7.

[0037] The embodiments disclosed in this utility model are preferred embodiments, but not limited to this. Those of ordinary skill in the art can easily understand the spirit of this utility model according to the above embodiments and make different extensions and changes. However, as long as they do not depart from the spirit of this utility model, they are within the protection scope of this utility model.
