Technical Field
[0001] This utility model relates to the technical field of carbon emission detection equipment, and in particular to a building energy consumption carbon emission detection and testing device. Background Technology
[0002] The construction process involves multiple carbon emission sources, including construction machinery, transport vehicles, on-site power generation equipment, and the production and transportation of building materials. By monitoring carbon emission data at different stages in real time, the carbon footprint of each stage can be accurately quantified, providing a data foundation for subsequent energy-saving and carbon-reduction technology improvements. Carbon emission testing requires the use of building energy consumption carbon emission testing and inspection devices. These devices use sampling bags to collect gas samples from the locations to be tested, and then send the sampled gas into the interior of the carbon emission testing and inspection instrument for testing.
[0003] In the process of detecting carbon emissions from building energy consumption, the connection between the sampling bag and the testing instrument is usually fixed by screwing on a thread. This connection method is not only cumbersome to operate, but also time-consuming. When faced with carbon emission testing tasks involving large-scale building complexes or complex building structures, the existing connection method will significantly reduce the efficiency of carbon emission testing and inspection. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a building energy consumption carbon emission testing and inspection device, which has the advantage of quick connection and solves the problem that the existing threaded connection method between sampling bags and testing instruments will significantly reduce the efficiency of carbon emission testing and inspection.
[0005] This utility model provides the following technical solution: a building energy consumption carbon emission testing device, comprising a carbon emission testing instrument and a sampling bag. An exhaust pipe is fixedly connected to the surface of the sampling bag. Air inlet pipes are evenly distributed on the surface of the carbon emission testing instrument. Each air inlet pipe has a quick-connect assembly inside. The quick-connect assembly includes a first limiting ring and a second limiting ring fixedly connected to the inner wall surface of the air inlet pipe. A sealing ring is provided between the opposing surfaces of the first and second limiting rings. A connecting ring is fixedly connected between the inner wall surfaces of the air inlet pipe. The inner wall surface is uniformly fixed with locking teeth. The inside of the air inlet pipe is slidably connected with a pressing tube. The surface of the pressing tube is fixedly connected with a third limiting ring. The surface of the third limiting ring is fixedly connected with a compression spring. The end surface of the pressing tube is fixedly connected with a pressing ring plate. The sealing ring is elastic. The operator inserts the exhaust pipe of the sampling bag containing the gas to be tested into the air inlet pipe of the carbon emission testing instrument. During the insertion process, the exhaust pipe will come into contact with the sealing ring inside the air inlet pipe. The inner wall of the sealing ring and the surface of the exhaust pipe are tightly abutted to seal the contact point and prevent gas leakage.
[0006] Preferably, the sampling bag is used to collect the gas to be tested, and the exhaust pipe is slidably connected inside the intake pipe.
[0007] Preferably, the inner walls of the sealing rings abut against the surface of the exhaust pipe, and the connecting rings are located on the side near the pressing tube. The inner walls of the sealing rings abut tightly against the surface of the exhaust pipe, so that a sealing layer is formed between the exhaust pipe and the inside of the intake pipe to prevent gas leakage during the process of entering the carbon emission testing instrument.
[0008] Preferably, the third limiting ring is slidably connected inside the air intake pipe, and the third limiting ring can limit the pressing tube and prevent the pressing tube from sliding out of the air intake pipe.
[0009] Preferably, all the retaining teeth are inclined, and the surface of the retaining teeth away from the connecting ring abuts against the surface of the exhaust pipe, and all the retaining teeth are elastic.
[0010] Preferably, the other end of the compression spring is fixedly connected to the end surface of the connecting ring near the third limiting ring, the pressing annular plate is disposed on the outside of the air intake pipe, the exhaust pipe is slidably connected to the inside of the pressing tube, and the compression spring provides the pressing tube with the ability to reset through the third limiting ring.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] 1. With the quick-connect component, during the testing process, the operator only needs to insert the exhaust pipe of the sampling bag into the inlet pipe. The automatic limiting of the locking teeth and the sealing effect of the sealing ring quickly establish the gas passage, allowing the gas to be tested to quickly enter the testing instrument for analysis. After the test is completed, pressing the ring plate can quickly release the locking teeth from the exhaust pipe, realizing the rapid separation of the sampling bag from the testing instrument. This significantly shortens the preparation and completion time before and after the test, improves the overall testing efficiency, and is especially suitable for scenarios that require frequent replacement of sampling bags for multi-point and multi-batch testing.
[0013] 2. The sealing ring and the locking teeth work together to provide double protection for the testing process. The sealing ring, by tightly abutting against the surface of the exhaust pipe, effectively prevents gas leakage at the connection point, ensuring that the gas to be tested can enter the testing instrument for analysis completely and accurately. At the same time, the inclined design and elastic deformation characteristics of the locking teeth not only achieve reliable limiting of the exhaust pipe, but also buffer the impact of external vibration or impact on the connection stability to a certain extent, further improving the reliability of the testing process and effectively reducing the testing error caused by gas leakage or loose connection, thereby ensuring the accuracy of building energy consumption carbon emission testing results.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1 - Figure 3This utility model provides an embodiment of a building energy consumption carbon emission testing device, comprising a carbon emission testing instrument 1 and a sampling bag 2. An exhaust pipe 3 is fixedly connected to the surface of the sampling bag 2. An air inlet pipe 4 is uniformly arranged on the surface of the carbon emission testing instrument 1. Each air inlet pipe 4 has a quick-connect assembly 5 inside. The quick-connect assembly 5 includes a first limiting ring 51 and a second limiting ring 52 fixedly connected to the inner wall surface of the air inlet pipe 4. A sealing ring 53 is provided between the opposing surfaces of the first limiting ring 51 and the second limiting ring 52. A connecting ring 54 is fixedly connected between the inner wall surfaces of the air inlet pipe 4. A locking tooth 55 is uniformly fixedly connected to the inner wall surface of the connecting ring 54. A pressing tube 56 is slidably connected inside the air inlet pipe 4. A third limiting ring 57 is fixedly connected to the surface of the pressing tube 56. A compression spring 58 is fixedly connected to the surface of the positioning ring 57, and a pressing annular plate 59 is fixedly connected to the end surface of the pressing tube 56. The sampling bag 2 is used to collect the gas to be tested. The exhaust pipe 3 is slidably connected to the inside of the air inlet pipe 4. The inner walls of the sealing rings 53 all abut against the surface of the exhaust pipe 3. The connecting ring 54 is located on the side near the pressing tube 56. The third limiting ring 57 is slidably connected to the inside of the air inlet pipe 4. The third limiting ring 57 can limit the pressing tube 56. The locking teeth 55 are all inclined. The surface of the locking teeth 55 away from the connecting ring 54 abuts against the surface of the exhaust pipe 3. The other end of the compression spring 58 is fixedly connected to the surface of the connecting ring 54 near the third limiting ring 57. The pressing annular plate 59 is located on the outside of the air inlet pipe 4. The exhaust pipe 3 is slidably connected to the inside of the pressing tube 56.
[0020] Please see Figure 1 - Figure 3When the operator presses the pressing ring plate 59 on the outside of the air intake pipe 4, the applied external force is directly transmitted to the end of the pressing tube 56, which is fixedly connected to the pressing ring plate 59. The pressing tube 56 slides axially inside the air intake pipe 4, and the third limiting ring 57 fixedly connected to its surface slides synchronously along the inner wall of the air intake pipe 4. Since the third limiting ring 57 is slidably connected to the inner wall of the air intake pipe 4, the pressing tube 56 can always maintain its axial trajectory during the sliding process of the third limiting ring 57, avoiding radial displacement of the pressing tube 56, thereby accurately compressing the compression spring 58. When compressed, the compression spring 58 undergoes elastic deformation, and the elastic potential energy stored within it increases with the amount of compression. Simultaneously, the other end of the compression spring 58 is fixedly connected to the surface of the connecting ring 54, maintaining contact with the connecting ring 54 throughout the compression process to ensure stable force transmission. As the pressing tube 56 moves towards the connecting ring 54, its inner wall gradually applies radial thrust to the inclined locking teeth 55. Because the roots of the locking teeth 55 are fixedly connected to the inner wall of the connecting ring 54, and the locking teeth 55 have an overall inclined elastic structure, the radial... Under the thrust, the end surface of the retaining tooth 55 away from the connecting ring 54 gradually disengages from the surface of the exhaust pipe 3. At this time, the retaining tooth 55 undergoes elastic deformation, and its tilt angle gradually decreases until it completely releases the radial limiting effect on the exhaust pipe 3. Simultaneously, after the exhaust pipe 3 loses the limiting effect of the retaining tooth 55, it is only subjected to the axial frictional force of the sealing ring 53. This frictional force is much smaller than the external force applied by the operator. Therefore, the exhaust pipe 3 can be easily pulled out of the intake pipe 4. During the process of pulling out the exhaust pipe 3, the sealing ring 53 and the surface of the exhaust pipe 3... The system maintains elastic contact until the exhaust pipe 3 is completely removed from the sealing area of the sealing ring 53. At this point, the elastic potential energy stored in the compression spring 58 begins to be released, pushing the third limit ring 57 and the pressing tube 56 to slide in the opposite direction until the pressing tube 56 returns to its initial position. The locking teeth 55 return to their tilted state under the action of their own elastic restoring force, preparing for the next test. The entire removal process is smooth and without jamming, ensuring that the operator can quickly complete the separation operation of the sampling bag 2 and the carbon emission testing instrument 1, improving the efficiency of testing.
[0021] Working principle: When in use, the operator inserts the exhaust pipe 3 of the sampling bag 2 containing the gas to be tested into the inlet pipe 4 of the carbon emission testing instrument 1. During insertion, the exhaust pipe 3 first contacts the surface of the retaining teeth 55. As the exhaust pipe 3 continues to enter, the retaining teeth 55 deform. Since the retaining teeth 55 are all inclined, the exhaust pipe 3 exerts a pushing force on the retaining teeth 55 towards the connecting ring 54 during insertion. However, the inclined structure of the retaining teeth 55 allows the exhaust pipe 3 to slide smoothly past the retaining teeth 55. At the same time, the surface of the retaining teeth 55 away from the connecting ring 54 gradually abuts against the surface of the exhaust pipe 3, providing a certain limiting effect on the exhaust pipe 3. Subsequently, the exhaust pipe 3 will contact the first limiting ring 51 and the second limiting ring 52 set on the inner wall surface of the inlet pipe 4. The sealing ring 53 between the two contacts, and the inner wall of the sealing ring 53 abuts tightly against the surface of the exhaust pipe 3 to seal the contact point and prevent gas leakage. At this time, the gas to be tested in the sampling bag 2 can enter the carbon emission testing instrument 1 through the exhaust pipe 3 and the air inlet pipe 4 for testing. After the testing is completed, the operator presses the pressing ring plate 59 set on the outside of the air inlet pipe 4. The pressing ring plate 59 drives the pressing tube 56 to slide in the air inlet pipe 4, compressing the spring 58. At the same time, the pressing tube 56 moves in the direction of the connecting ring 54 and pushes the locking teeth 55, so that the locking teeth 55 separate from the surface of the exhaust pipe 3 and release the limit on the exhaust pipe 3. At this time, the operator can pull the exhaust pipe 3 out of the air inlet pipe 4 to complete the entire testing process.
