Description

Technical Field

[0001] The utility model belongs to the technical field of condenser production and its related equipment, and particularly relates to a leak detection device for condenser copper tubes after assembly. Background Technique

[0002] With the development of society and technology, the equipment in various fields has been greatly improved. The condenser is a component of the refrigeration system and belongs to a type of heat exchanger. It can convert gas or steam into liquid and transfer the heat in the tubes to the air near the tubes in a very fast manner. Among them, the copper tube is one of the important accessories in the condenser. And after the copper tube is assembled inside the condenser, generally a leak detection device is needed to detect the copper tube to avoid affecting the normal use of the subsequent condenser.

[0003] After retrieval, the publication number is CN217107292U, and the application date is March 21, 2022, which discloses a leak detection device for the copper tubes of a hydro-generator unit cooler, including a "U"-shaped hanging assembly and a pipe head for connecting the external water pipe and the copper tube of the cooler; a slideway is arranged on the hanging assembly, and an I-shaped slider is slidably installed in the slideway. The two ends of the slider are respectively a rectangular adapter block and a limiting ring, and the adapter block and the limiting ring are respectively attached to the opposite side walls of the hanging assembly. The side wall of the adapter block is attached to the inner wall of the slideway. A threaded through hole is opened on the slider, and a top rod for pressing the pipe head against the end of the copper tube of the cooler is installed in threaded fit; one end of the hanging assembly is a fixed end, and a connecting screw is fixed at the other end of the hanging assembly and is slidably installed in the middle of the hanging assembly through the connecting screw. A nut is installed in threaded fit at the movable end of the connecting screw.

[0004] However, it still has the following disadvantages in actual use:

[0005] When the above-mentioned leak detection device for the copper tubes of the hydro-generator unit cooler is in use, the pipe head is pushed to be connected with the copper tube for detection through structures such as a handle and a top head. However, this method is rather cumbersome and time-consuming and laborious in the process of the staff docking the pipelines, resulting in low work efficiency;

[0006] 2. When the above-mentioned leak detection device for the copper tubes of the hydro-generator unit cooler is in use, the single copper tube is detected through the pipe head. However, this method has low efficiency in the detection process, and the detection water will be discharged from the other end of the copper tube during the detection process, resulting in waste of water resources. For this reason, we provide a leak detection device for condenser copper tubes after assembly to solve the above problems. Content of the Utility Model

[0007] The purpose of the present utility model is to provide a leak detection device for condenser copper tubes after assembly. By setting a limiting component, it is convenient for workers to quickly disassemble and assemble and dock the copper tube body, saving time and effort and having high work efficiency. In addition, by using a flow splitting plate and a flow combining plate, leak detection operations can be carried out on multiple groups of copper tube bodies, improving the detection efficiency. At the same time, the water flow can be circulated for detection use, reducing water resource waste.

[0008] To solve the above technical problems, the present utility model is realized through the following technical solutions:

Guide rods are arranged at both inner ends between the adjacent end faces of the upper clamping plate and the lower clamping plate.

[0016] The present utility model is further arranged such that the top end of the guide rod sequentially passes through the through hole at the bottom of the upper fixing plate and the through hole at the bottom of the upper clamping plate and is connected to the bottom of the upper baffle.

The springs are sleeved on the outer side of the outer wall of the guide rod, and the front end faces of the upper fixing plate and the lower fixing plate are fixed to the top and bottom of the rear end face of the docking frame.

[0018] The present utility model has the following beneficial effects:

[0019] By providing the limiting component, the present utility model can drive the upper clamping plate and the lower clamping plate to move upward or downward under the elastic performance of the spring, so as to realize or cancel the limiting effect on the outer clamping ring on the outer wall of the copper tube body, thereby facilitating the staff to quickly disassemble and assemble and dock the copper tube body, saving time and effort, and having high work efficiency. It solves the problem that in the use of the above-mentioned copper tube leak detection device for the cooler of the water turbine generator set, the tube head is pushed to connect and detect with the copper tube through structures such as a handle and a top head, and this method is rather cumbersome and time-consuming and laborious in the process of the staff docking the pipeline, resulting in low work efficiency.

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention. Specific Embodiment 1

[0031] Please refer to Figures 1 to 4 , the present invention is a leak detection device after the assembly of condenser copper tubes, including a manifold plate 1 and a confluence plate 2 arranged on one side thereof. The front ends of the manifold plate 1 and the confluence plate 2 are evenly spaced in the horizontal direction and provided with docking frames 105.

[0032] Specifically, the water inlet end of the manifold plate 1 is respectively connected to the drain pipe 101, the external water pipe 102 and the circulation pipe 201 through a quarter joint. The water outlet end of the confluence plate 2 is connected to the other end of the circulation pipe 201 through a pipe joint. The front end face of the manifold plate 1 is evenly spaced in the horizontal direction and provided with diverging pipes 103. The other ends of the diverging pipes 103 are connected to the delivery pipe 104 through pipe joints. The front end face of the confluence plate 2 is evenly spaced in the horizontal direction and provided with confluence pipes 202. The other ends of the confluence pipes 202 are connected to the delivery pipe 104 through pipe joints. The other end of the delivery pipe 104 is arranged at the center position of the rear end face of the adjacent docking frame 105. The inner side wall of the docking frame 105 is provided with a sealing ring 1051, and the copper tube body 106 is installed inside the docking frame 105. An outer snap ring 1061 is arranged at the edge of one side of the outer wall of the copper tube body 106.

[0033] Furthermore, the flow splitter 1 serves to split the flow, the flow combiner 2 serves to combine the flow, the four-way joint and the pipe joint both serve to connect pipelines. Valves are provided on the flow splitter pipe 103, the flow combiner pipe 202, the external water pipe 102, and the drain pipe 101. The sealing ring 1051 can improve the sealing performance at the pipeline connection.

[0034] The operation process of this embodiment is as follows: A plurality of flow splitter pipes 103 and flow combiner pipes 202 are respectively provided on the flow splitter 1 and the flow combiner 2, and the ends of the flow splitter pipes 103 and the flow combiner pipes 202 are connected to the conveying pipe 104 through pipe joints. A plurality of docking frames 105 are provided on the conveying pipe 104. One end of the plurality of flow splitter pipes 103 on the flow splitter 1 and their connected docking frames 105 are connected to one end of the copper pipe body 106, and the other end of the plurality of flow combiner pipes 202 on the flow combiner 2 and their connected docking frames 105 are connected to the other end of the copper pipe body 106. Therefore, multiple copper pipe bodies 106 can be connected and leak detection can be performed to detect whether there is liquid leakage, and then leak detection operations can be carried out on multiple groups of copper pipe bodies 106 to improve the detection efficiency. During the detection process, water is introduced into the copper pipe body 106 through the external water pipe 102. After the water flows through the inside of the copper pipe body 106, it will be combined by the flow combiner 2 and then circulated back to the copper pipe body 106 through the circulation pipe 201, playing a role in water flow circulation detection and reducing water resource waste. Specific Embodiment Two

[0035] Please refer to Figures 4 to 5 , based on Specific Embodiment One, what is different from the first embodiment is that a limiting component 3 is provided. The limiting component 3 includes an upper clamping plate 301 and a lower clamping plate 302 located directly below it. The rear edges of the outer walls on both sides of the upper clamping plate 301 and the lower clamping plate 302 are movably connected to adjacent connecting rods 303 through hinges, solving the problem that the existing steps for workers to dock pipelines are relatively cumbersome, time-consuming and laborious, resulting in low work efficiency.

[0036] Specifically, the other ends of the upper and lower adjacent connecting rods 303 are movably connected to the adjacent upper and lower surfaces of the pressing plate 304 through hinges. Guide rods 305 are provided at both inner ends between the adjacent end faces of the upper clamping plate 301 and the lower clamping plate 302. The top of the guide rod 305 sequentially passes through the through holes at the bottom of the upper fixing plate 306 and the through holes at the bottom of the upper clamping plate 301 and is connected to the bottom of the upper baffle 308. The bottom of the guide rod 305 sequentially passes through the through holes at the top of the lower fixing plate 307 and the through holes at the top of the lower clamping plate 302 and is connected to the top of the lower baffle 309. Springs 3010 are provided on both sides between the upper clamping plate 301 and the upper baffle 308, and springs 3010 are provided on both sides between the lower clamping plate 302 and the lower baffle 309, and the springs 3010 are sleeved on the outer side of the outer wall of the guide rod 305. The front end faces of the upper fixing plate 306 and the lower fixing plate 307 are fixed to the top and bottom of the rear end face of the docking frame 105.

[0037] Further, the upper clamping plate 301 and the lower clamping plate 302 are identical in shape and size. The cross-sections of the upper clamping plate 301 and the lower clamping plate 302 are both L-shaped. The upper clamping plate 301 and the pressing plate 304, as well as the lower clamping plate 302 and the pressing plate 304, are connected by a connecting rod 303 and a hinge to play a transmission role. The guide rod 305 plays a role in limiting and assisting the sliding of the upper clamping plate 301 and the lower clamping plate 302. The upper baffle 308 and the lower baffle 309 play a role in limiting the spring 3010. Under the elastic performance of the spring 3010, the upper clamping plate 301 and the lower clamping plate 302 can be driven to move.

[0038] The operation process of this embodiment is as follows: First, push the two pressing plates 304 inward. The top and bottom of the pressing plate 304 are movably connected to the outer walls of the upper clamping plate 301 and the lower clamping plate 302 under the action of the hinge and the connecting rod 303 respectively. Therefore, when the pressing plate 304 is forced to move inward, it will push the upper clamping plate 301 and the lower clamping plate 302 to move upward and downward under the action of the connecting rod 303 and the hinge. The upper clamping plate 301 and the lower clamping plate 302 will move under the auxiliary action of the guide rod 305 when they are stressed, and will compress the spring 3010. At this time, the upper clamping plate 301 can be driven to move upward, and the lower clamping plate 302 can be driven to move downward, so that the upper clamping plate 301 and the lower clamping plate 302 are respectively moved out of the docking frame 105. Then, insert the cooler copper tube body 106 into the docking frame 105, and make the inner end of the copper tube body 106 closely adhere to the outer wall of the sealing ring 1051 to improve the sealing performance. Then, stop applying force to the pressing plate 304. At this time, under the elastic performance of the spring 3010, the upper clamping plate 301 and the lower clamping plate 302 can be bounced back to the initial position, and the outer clamping ring 1061 on the outer wall of the copper tube body 106 can be limited by the upper clamping plate 301 and the lower clamping plate 302. Thus, it is convenient for the staff to quickly disassemble and assemble the docking copper tube body 106, saving time and effort and having high work efficiency.
