Description
Technical Field
[0001] The utility model relates to the technical field of building ventilation pipes, in particular to a detection device for heating ventilation pipes. Background Technique
[0002] HVAC is a part of a building. Its full name in the subject classification is heating, gas supply, ventilation and air conditioning engineering, including: heating, ventilation, and air conditioning. Functionally, it is also an essential part of future homes. The ventilation duct is composed of multiple pipe segments spliced together. The pipe segments are prefabricated in the factory. Basically, there is no air leakage when there is no obvious damage or deformation on the appearance. Most of the air leakage positions occur at the splicing joints between the pipe segments. Therefore, usually, it is to detect whether there is air leakage at the splicing joints between the pipe segments.
[0003] Some traditional detection methods are to block both ends of the ventilation pipe, then inject a certain air pressure into the interior of the ventilation pipe through an air pump, then dip a brush in soapy water, and then manually apply it to the splicing joints, and then check whether bubbles appear for detection. However, these operations are all manually performed, which is time-consuming and reduces work efficiency. Therefore, it is urgent to solve such problems. Content of the Utility Model
[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to provide a detection device for heating ventilation pipes.
[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0006] A detection device for heating ventilation pipes includes a heating ventilation pipe. One end of the heating ventilation pipe is provided with a sealing mechanism. The outside of the sealing mechanism is provided with a coating mechanism for detecting its sealing performance. The outer wall of the heating ventilation pipe is provided with a spraying mechanism for spraying soapy water on the coating mechanism;
[0007] The coating mechanism includes a rotating ring rotatably connected to the outer wall of one of the heating ventilation pipes. One end of the rotating ring is provided with a second slot at the top, and one side of the inner wall of the second slot is fixed with a mounting plate. Both sides of the outer wall of one end of the mounting plate are fixed with fixing plates. One of the fixing plates is provided with a through groove at both ends. A connecting rod is inserted into the second slot on the side of the other fixing plate away from the mounting plate. A limiting groove is provided on one side of the connecting rod. Through holes are provided on both sides of the mounting plate and communicate with each other. A sliding rod is slidably arranged in the through holes. A limiting block is fixed on the side of the sliding rod close to the connecting rod, and the limiting block is adapted to the limiting groove. One end of the limiting block is an arc surface. A brush is installed on the other side of the connecting rod, and the bottom of the brush is in contact with the splicing joint of the heating ventilation pipe.
[0008] As a further solution of the utility model, a moving block is fixed on the side of the sliding rod away from the limiting block, and the moving block passes through the sliding groove.
[0009] As a further solution of the utility model, a spring is fixed at one end of the mounting plate close to the connecting rod. The other end of the spring is fixed to one end of the limiting block, and the spring is located on the outer wall of the sliding rod. By moving the moving block, the limiting of the connecting rod can be released, and thus the brush can be quickly disassembled and installed.
[0010] As a further solution of the utility model, the sealing mechanism includes a connecting ring. Blocks are fixed at both ends of the connecting ring, and HVAC ventilation pipes are respectively clamped on the mutually remote sides of the two blocks.
[0011] As a further solution of the utility model, a second gear is fixed on the outer wall of the rotating ring. A first mounting shell is installed on one outer wall of the HVAC ventilation pipe. A second mounting shell is fixed at one end of the first mounting shell. One end of the inner wall of the first mounting shell is rotatably connected to a rotating shaft. A first gear is fixed at one end of the rotating shaft close to the second gear, and the first gear meshes with the second gear. A motor is installed inside the second mounting shell, and the output shaft of the motor is fixedly connected to one end of the rotating shaft. A spraying mechanism is arranged at the other end inside the first mounting shell. When the first gear drives the second gear to rotate, the second gear will drive the brush to rotate and coat soapy water at the splicing part of the two HVAC ventilation pipes.
[0012] As a further solution of the utility model, the spraying mechanism includes a liquid storage tank arranged at the bottom of the other end inside the first mounting shell. A liquid injection port communicating with its interior is connected to the top of one outer wall of the liquid storage tank. A water pump is installed on the top of the liquid storage tank. The water inlet end of the water pump is connected to a connecting pipe and is arranged inside the liquid storage tank. The water outlet end of the water pump is connected to a conveying pipe. The other end of the conveying pipe is connected to a communicating water outlet pipe. A plurality of mist nozzles are arranged on one side of the water outlet pipe close to the splicing part of the two HVAC ventilation pipes. The mist nozzles will spray out the soapy water inside the liquid storage tank in a mist form and attach it to the splicing part to prevent the soapy water from quickly flowing away.
[0013] As a further solution of the utility model, sealing rings are arranged at the mutually remote ends of the two HVAC ventilation pipes. Through holes are formed at both ends of one of the sealing rings, and an air inlet pipe is connected inside the holes. The air inlet pipe is connected to an external air pump device to inject a certain air pressure into the interior of the HVAC ventilation pipe.
[0014] The beneficial effects of the utility model are:
[0015] The utility model: Due to the adoption of a rotating shaft, a second gear, a connecting rod brush, a water pump, a liquid storage tank, and a mist spray head, when the motor drives the rotating shaft to rotate, the rotating shaft will drive the first gear to mesh with the second gear and drive it to rotate. Then, the soapy water inside the liquid storage tank is pumped out by the water pump and sprayed through the mist spray head at a certain position of the splicing joint. When the brush rotates to a position with soapy water, the soapy water will be coated on other positions of the splicing joint. By observing whether bubbles appear at the splicing joint, it effectively solves the problem in the background technology that manual coating is carried out at the splicing joint and then it is checked whether bubbles appear for detection. However, this kind of operation is all carried out manually, which is time-consuming and reduces the work efficiency. Furthermore, it realizes automatic coating at the splicing joint and reduces the manual workload.
[0016] The utility model: Due to the adoption of a connecting rod, a limiting groove, a limiting block, a sliding rod, and a moving block, when the moving block is moved, the sliding rod will be driven to move by the moving block, and the sliding rod will drive the limiting block away from the limiting groove, and the limiting block will release the limitation on the connecting rod. At this time, the brush can be quickly disassembled and installed. Brief Description of the Drawings

[0025] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Next, the present invention will be described in detail with reference to the drawings and in conjunction with the embodiments.
[0026] Refer to Figures 1-6 , a detection device for an HVAC ventilation pipe, including an HVAC ventilation pipe 1. One end of the HVAC ventilation pipe 1 is provided with a sealing mechanism.

A connecting rod 501 is inserted into the second notch on the side of the other fixed plate 502 away from the mounting plate 505. A limiting groove 506 is opened on one side of the connecting rod 501. Through holes communicating with each other are opened on both sides of the mounting plate 505, and slide bars 508 are slidably arranged in the through holes. A limiting block 507 is fixed to the side of the slide bar 508 close to the connecting rod 501, and the limiting block 507 is adapted to the limiting groove 506. One end of the limiting block 507 is an arc surface. A brush 5 is installed on the other side of the connecting rod 501, and the bottom of the brush 5 is in contact with the splicing part of the HVAC ventilation pipe 1.
[0028] In this embodiment, a moving block 503 is fixed to the side of the slide bar 508 away from the limiting block 507, and the moving block 503 passes through the chute 504.
[0029] In this embodiment, a spring 509 is fixed to one end of the mounting plate 505 close to the connecting rod 501. The other end of the spring 509 is fixed to one end of the limiting block 507, and the spring 509 is located on the outer wall of the sliding rod 508. By moving the moving block 503, the limit on the connecting rod 501 can be released, and thus the brush 5 can be quickly disassembled and installed.
[0030] In this embodiment, the sealing mechanism includes a connecting ring 101. Clamping blocks 102 are fixed to both ends of the connecting ring 101, and the two clamping blocks 102 are respectively clamped to a heating and ventilation pipe 1 on the side facing away from each other.
[0031] In this embodiment, a second gear 401 is fixed to the outer wall of the rotating ring 4. A first mounting shell 2 is installed on one side outer wall of the heating and ventilation pipe 1. A second mounting shell 3 is fixed to one end of the first mounting shell 2. One end of the inner wall of the first mounting shell 2 is rotatably connected to a rotating shaft 302. A first gear 303 is fixed to one end of the rotating shaft 302 close to the second gear 401, and the first gear 303 meshes with the second gear 401. A motor 301 is installed inside the second mounting shell 3, and the output shaft of the motor 301 is fixedly connected to one end of the rotating shaft 302. A spraying mechanism is provided at the other end inside the first mounting shell 2. When the first gear 303 drives the second gear 401 to rotate, the second gear 401 will drive the brush 5 to rotate and coat soapy water on the splicing part of the two heating and ventilation pipes 1.
[0032] In this embodiment, the spraying mechanism includes a liquid storage tank 6 provided at the bottom of the other end inside the first mounting shell 2. A liquid injection port 601 communicating with its interior is connected to the top of one side outer wall of the liquid storage tank 6.

[0033] In this embodiment, sealing rings 104 are provided at the ends of the two heating and ventilation pipes 1 away from each other. Through holes are opened at both ends of one of the sealing rings 104, and an air inlet pipe is connected inside the holes. The air inlet pipe is connected to an external air pump device, and thus a certain air pressure is injected into the interior of the heating and ventilation pipe 1.
[0034] Working principle: When in use, first, splice two HVAC ventilation pipes 1 through the clamping block 102, and then insert the connecting rod 501 into the inner part of one end of the second notch. At this time, the connecting rod 501 will squeeze the arc surface of the limiting block 507, and the limiting block 507 will drive the sliding rod 508 to move. When the limiting block 507 moves into the limiting groove 506, the spring 509 will reset the limiting block 507, and the limiting block 507 will limit the connecting rod 501. The brush 5 will contact the splicing part of the two HVAC ventilation pipes 1. Move the moving block 503, the moving block 503 will drive the sliding rod 508 to move, and the sliding rod 508 will drive the limiting block 507 to release the limit on the connecting rod 501, so that the brush 5 can be quickly disassembled and installed. Then, seal the mutually remote ends of the HVAC ventilation pipes 1 with the sealing rings 104 respectively. Then connect the air inlet pipe to an external air pump device, inject a certain air pressure into the HVAC ventilation pipes 1 through the air pump, and then operate the motor 301. The motor 301 will drive the rotating shaft 302 to rotate, and the rotating shaft 302 will drive the first gear 303 to mesh with the second gear 401 to drive it to rotate. The second gear 401 will drive the brush 5 to rotate at the splicing part of the two HVAC ventilation pipes 1. At this time, operate the water pump 602 to pump out the soapy water in the liquid storage tank 6, transport the soapy water to the water outlet pipe 604 through the delivery pipe 603, and then spray it out through the atomizing nozzle 605. The sprayed soapy water will first stay at the splicing part for a period of time. When the brush 5 rotates to the soapy water, it will smear the soapy water evenly at the splicing part of the two HVAC ventilation pipes 1. Then, check whether there are bubbles at the splicing part for subsequent maintenance and processing.
