Description

Technical Field

[0001] This utility model belongs to the technical field of duct testing devices, specifically relating to a fiberglass duct testing device. Background Technology

[0002] The FRP (fiberglass reinforced plastic) duct testing device is mainly used to test the quality, performance, and durability of FRP ducts during use. Its applications include ventilation and air conditioning systems, industrial exhaust systems, etc., ensuring that the ducts maintain good working condition during long-term use.

[0003] Problems with existing technology:

[0004] Existing duct inspection methods often use air tightness tests to check whether the duct connections are up to standard. While these tests can determine whether the duct is properly sealed, they do not easily pinpoint the location of the leak. Furthermore, once a leak is found, there may be a second or more leaks, making troubleshooting quite complicated. Utility Model Content

[0005] The purpose of this invention is to provide a fiberglass duct inspection device. A strong light source, provided by a penetrating lamp on the inspection vehicle, allows workers to observe leaks on the outside of the fiberglass duct. By rotating the aiming ring and the calibration beam, the worker aligns the calibration beam with the leak point, thus temporarily sealing it. Simultaneously, the rotating legs at both ends of the inspection vehicle allow it to adapt to fiberglass ducts of different diameters. The steering legs allow the inspection vehicle to adjust its orientation within slightly curved fiberglass ducts, thus broadening its versatility.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A fiberglass duct testing device includes: a control console, an air pressure injector on one side of the control console, a fiberglass duct on one side of the air pressure injector, the air pressure injector and the fiberglass duct being connected by a connecting pipe, and a testing cart being movably placed inside the fiberglass duct.

[0008] The testing vehicle includes a corrugated storage tank, with a vehicle head at each end. A testing sealing ring is located near one of the vehicle heads, with a penetrating light lamp fixedly mounted on the outer side of the testing sealing ring. An aiming ring is slidably mounted in the middle of the testing sealing ring, and a spray rod is fixedly connected to the outer side of the aiming ring. A calibration beam is fixedly mounted on the outer side of the spray rod. A hydraulic press is fixedly mounted on the side of the vehicle head corresponding to the aiming ring. The output end of the hydraulic press is connected to the spray rod, and the inlet end of the hydraulic press is connected to the corrugated storage tank.

[0009] A drive motor is fixedly connected to the side of the vehicle head near the aiming ring. A drive wheel is fixedly connected to the output end of the drive motor, and the drive wheel is engaged with the aiming ring.

[0010] The front of the vehicle is equipped with four movable legs that rotate inside. The four movable legs are arranged in pairs, one above the other and symmetrically positioned. Steering legs are slidably installed on both sides of the front of the vehicle.

[0011] A fixing groove is fixedly connected to the position of the steering leg at the front of the vehicle, and a directional spring is fixedly connected between the steering leg and the fixing groove.

[0012] A sliding deployment rod is vertically slidably installed between the two moving legs at the front of the vehicle. A deployment motor is fixedly installed below the sliding deployment rod at the front of the vehicle. A deployment screw is fixedly connected to the output end of the deployment motor. The deployment screw is threadedly connected to the sliding deployment rod. A deployment sliding rod is fixedly connected to the side of the sliding deployment rod near the moving leg. The end of the deployment sliding rod is slidably installed with the moving leg.

[0013] The technical effects achieved by this utility model are as follows:

[0014] This invention allows workers to observe leaks on the outside of fiberglass ducts by using a strong light emitted from a penetrating lamp installed on a testing vehicle. By rotating the aiming ring and the beam of the calibration beam, the calibration beam is aligned with the location of the leak, thereby temporarily sealing the leak.

[0015] In this invention, the rotating movable legs at both ends of the inspection vehicle allow the vehicle to adapt to fiberglass ducts of different diameters, and the steering leg design allows the inspection vehicle to adjust its orientation within the slightly curved fiberglass duct, making it more versatile.

[0026] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0027] like Figure 1 - Figure 2 As shown, a fiberglass duct testing device includes: a control console 1, an air pressure injector 2 on one side of the control console 1, a fiberglass duct 4 on one side of the air pressure injector 2, the air pressure injector 2 and the fiberglass duct 4 being connected by a connecting pipe 3, and a testing cart 5 being movably placed inside the fiberglass duct 4.

[0028] When inspecting fiberglass ducts, the inspection vehicle 5 is first placed inside the fiberglass duct 4. Then, the two ends of the fiberglass duct 4 are sealed, leaving only the connecting pipe 3 connected. The control console 1 controls the air pressure injector 2 to inject gas into the fiberglass duct 4 to increase the pressure inside the fiberglass duct 4. When the pressure inside the fiberglass duct 4 reaches the predetermined value, the pressure is maintained. The air flow rate that is continued to be injected is the leakage amount of the fiberglass duct 4.

[0029] When a leak needs to be found, the detection vehicle 5 can be started and moved inside the fiberglass duct 4. Light is emitted from the detection vehicle 5 through the leak and the leak is sealed with sealant until the connecting pipe 3 no longer needs to be injected with air.

[0030] See attached document Figure 3 - Figure 5The testing vehicle 5 includes a corrugated storage tank 502, with a vehicle head 501 at each end. A testing sealing ring 507 is located near the corrugated storage tank 502 on one of the vehicle heads 501. A penetrating light lamp 506 is fixedly installed on the outer side of the testing sealing ring 507. An aiming ring 511 is slidably installed in the middle of the testing sealing ring 507. A spray rod 505 is fixedly connected to the outer side of the aiming ring 511, and a calibration beam 508 is fixedly installed on the outer side of the spray rod 505. A hydraulic press 512 is fixedly installed on the side of the vehicle head 501 corresponding to the aiming ring 511. The output end of the hydraulic press 512 is connected to the spray rod 505, and the inlet end of the hydraulic press 512 is connected to the corrugated storage tank 502. A drive motor 509 is also fixedly connected to the side of the vehicle head 501 near the aiming ring 511. A drive wheel 510 is fixedly connected to the output end of the drive motor 509, and the drive wheel 510 meshes with the aiming ring 511.

[0031] Based on the above structure, the airflow maintaining the pressure inside the fiberglass duct 4 via the connecting pipe 3 is used to determine if there is a leak. If a leak is found, the detection vehicle 5 is started and moves inside the fiberglass duct 4, and the penetrating light lamp 506 is turned on to emit a strong light. The light will leak through gaps or thinner parts of the fiberglass duct 4 to the outside of the fiberglass duct 4, which can be observed by personnel on the outside of the fiberglass duct 4. At this time, the drive motor 509 is started to rotate the aiming ring 511 to adjust the orientation of the spray rod 505. At the same time, the calibration beam 508 is turned on to emit a beam with a large color difference from the light from the penetrating light lamp 506, so that the beam passes through the position where the light from the penetrating light lamp 506 shines. Then, the hydraulic press 512 is started to spray sealant onto the leak through the spray rod 505 to temporarily seal the leak. Then, the reading on the control panel 1 is observed to see if there is still a leak. This process is repeated until the reading is zero.

[0032] See attached document Figure 6 - Figure 8 The front of the vehicle 501 has four movable legs 503 rotatably mounted inside. The four movable legs 503 are arranged in pairs, one above the other, and are symmetrical. Steering legs 504 are slidably mounted on both sides of the front of the vehicle 501. A fixing groove 517 is fixedly connected to the front of the vehicle 501 corresponding to the position of the steering leg 504. A directional spring 513 is fixedly connected between the steering leg 504 and the fixing groove 517. A sliding unfolding rod 515 is vertically slidably mounted between the two movable legs 503 on the front of the vehicle 501. An unfolding motor 516 is fixedly mounted below the sliding unfolding rod 515 on the front of the vehicle 501. An unfolding screw 514 is fixedly connected to the output end of the unfolding motor 516. The unfolding screw 514 is threadedly connected to the sliding unfolding rod 515. An unfolding sliding rod 518 is fixedly connected to the side of the sliding unfolding rod 515 near the movable leg 503. The end of the unfolding sliding rod 518 is slidably mounted to the movable leg 503.

[0033] According to the above structure, when the inspection vehicle 5 is placed inside the fiberglass duct 4, the unfolding motor 516 is started to rotate the unfolding screw 514. The threads of the two sliding unfolding rods 515 are opposite. When the unfolding screw 514 rotates, the two sliding unfolding rods 515 move away from each other. Then, the moving leg 503 is rotated by the unfolding sliding rod 518, so that the moving legs 503 on the upper and lower sides move away from each other until they contact the inner wall of the fiberglass duct 4. The steering leg 504 is pressed to compress the fixing groove 517 and put the steering leg 504 into the fiberglass duct 4. When it is necessary to find the leakage point of the fiberglass duct 4, the motor at the end of the moving leg 503 is started to move the entire inspection vehicle 5 back and forth. The steering leg 504 is used to control the direction.

[0034] The working principle of this utility model is as follows: When testing the fiberglass duct, the testing vehicle 5 is first placed inside the fiberglass duct 4, and then the two ends of the fiberglass duct 4 are sealed, leaving only the connecting pipe 3 connected. The control console 1 controls the air pressure injector 2 to inject gas into the fiberglass duct 4 to increase the pressure inside the fiberglass duct 4. When the pressure inside the fiberglass duct 4 reaches the predetermined value, the pressure is maintained. The air flow rate that is continued to be injected is the leakage amount of the fiberglass duct 4.

[0035] When a leak needs to be found, the detection vehicle 5 can be started and moved inside the fiberglass duct 4. Light is emitted from the detection vehicle 5 through the leak and the leak is sealed with sealant until the connecting pipe 3 no longer needs to be injected with air.

[0036] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
