[0001] This utility model relates to the field of testing equipment technology, and in particular to a duct wind speed monitoring device. Background Technology
[0002] With the advancement and development of technology, industrial development and construction are also improving, and various deep processing factories are increasing. Due to different tool requirements, some deeper rooms will be built in the factories to meet the needs of designated storage or research environments. At the same time, these rooms still need their own ventilation requirements, so some pipeline ventilation facilities will be built to ensure the required ventilation.
[0003] Under normal circumstances, ventilation ducts that have been used for a long time need to be tested to ensure stable ventilation. This requires the use of airflow velocity testing equipment. Most of the existing testing equipment is handheld, which requires the tester to hold it at all times. This makes it inconvenient to operate at high or special locations, and makes it impossible to test the velocity stably and normally. Utility Model Content
[0004] This utility model relates to a duct wind speed monitoring device. A top pressure component is directly installed at the lower end of the main frame assembly, and a fixing component is installed at the bottom of the top pressure component. The main frame assembly can be held by hand and the top pressure component can be pulled downwards to achieve the effect of clamping the contact wheel of the main frame assembly at a designated position on the main duct. The head of the main frame assembly is convenient for installing the detection component. The detection component can isolate debris, and the detection component can be quickly installed through the quick-connect component, increasing the convenience of the device.
[0005] This utility model provides a duct wind speed monitoring device, specifically including: a main duct; an external fan is installed at the outer end of the main duct, a main frame assembly is installed on the main duct, a top pressure assembly is slidably installed at the lower end of the main frame assembly, a fixing assembly is fixed at the bottom of the top pressure assembly of the main frame assembly, a detection assembly is installed at the head of the main frame assembly, a quick-connect assembly is provided at the bottom of the detection assembly, and the detection assembly and the main frame assembly are connected by the quick-connect assembly.
[0006] The main frame assembly has a vertical long rod structure. A top bracket is provided near the top of the main frame. The top bracket is a triangular frame structure. A contact frame is oscillatingly installed on the top bracket. Four sets of contact wheels are rotatably installed at both ends of the contact frame.
[0007] The bottom slide of the top pressing assembly is triangular in shape, and an outer clamp is snapped onto the outer end of the bottom slide. The bottom slide with the outer clamp is slidably mounted on the main frame assembly. A top pressing frame is oscillatingly mounted on the upper end of the bottom slide. The top pressing frame is an arc-shaped structure, and six sets of contact wheels are rotatably mounted on both ends of the top pressing frame.
[0008] The fixing sleeve of the fixing component is fitted onto the bottom of the main frame component. The fixing sleeve is fixed to the outside by bolts. A horizontal support platform is provided at the upper end of the fixing sleeve. A spring plate is fixedly installed on the support platform. The top of the spring plate is in contact with the top pressure component.
[0009] The detector of the detection component adopts a deepened structure. A snap-fit cover is installed on the detector facing the external fan. A barrier net is provided on the snap-fit cover, and the outer end face of the barrier net is set with a sharp structure.
[0010] The connector of the quick-connect assembly is located at the bottom of the detection assembly. The connector is sleeved at the head of the main frame assembly. A reinforcing plate is provided at the sleeve position of the connector. The reinforcing plate is an extended structure with reinforcing ribs. A trigger frame is slidably installed at the root of the connector. The trigger frame is close to the main frame assembly. A notch is provided at the contact position between the trigger frame and the main frame assembly. A spring is provided at the outer end of the trigger frame.
[0011] This utility model provides a duct wind speed monitoring device, which has the following beneficial effects:
[0012] In this invention, a top-pressing component is first slidably installed at the lower end of the main frame assembly. A fixing component is installed at the bottom of the top-pressing component on the main frame assembly. The fixing component, through a spring plate, always pushes the top-pressing component upward, causing the contact wheels to contact each other. During snap-fit installation, simply hold the fixing component at the bottom of the main frame assembly and slide the top-pressing component toward the fixing component, placing the main frame assembly and the top-pressing component on the main air duct. Then, release the top-pressing component to achieve convenient installation and fixation of the device. The detection component at the top of the main frame assembly has a barrier net, which isolates larger debris, preventing the debris from affecting the detection component. The detection component is directly snap-fitted onto the main frame assembly through a quick-connect component. The trigger bracket set on the quick-connect component increases the convenience of assembling and disassembling the quick-connect component.
[0013] In addition, the main frame is designed as a long rod, which makes it easy to install various components on the main frame. The top clip is directly set on the main frame, and the triangular top clip is easy to cooperate with the top pressure component. It is easy to snap and install on the main air duct. The contact wheel of the contact bracket makes it easy to contact and fix with the curved wall of the main air duct.
[0014] In addition, the bottom slide is first set in a triangular shape, corresponding to the top clamp of the main frame assembly. The bottom slide is installed by snapping on the outside of the outer clamp, which allows the bottom slide to be easily installed and removed from the main frame assembly. The sliding bottom slide has the function of sliding and pressing against the top clamp of the main frame assembly to clamp the main air duct when in use. The top pressure frame is oscillatingly installed on the bottom slide. The top pressure frame is set in an arc structure, so that the contact wheel on the top pressure frame can better contact the outer wall of the main air duct through the arc structure, thereby stably achieving the effect of the top pressure frame and the contact frame of the main frame assembly clamping the main air duct.
[0015] In addition, to make the device easier to operate, the fixing sleeve is directly attached to the bottom of the main frame assembly and then fixed with bolts, making it convenient to use the main frame assembly by hand. The horizontal support platform on the fixing sleeve is fixed with a spring plate, and the top of the spring plate directly contacts the bottom of the top pressure assembly. At this time, you can directly hold the fixing assembly and slide it down to control the sliding of the top pressure assembly. When the top pressure assembly is released, the top pressure assembly will quickly rebound through the spring plate, and the spring plate will make the top pressure assembly and the main frame assembly stably clamp onto the main air duct.
[0016] In addition, to enable the detection components to better detect wind speed, the detector is deepened to increase the contact area of the detector blades, and the barrier mesh of the snap-fit cover is made into a sharp shape, so that the snap-fit cover and the barrier mesh can block larger debris, while the sharp barrier mesh will not block the flow of air.
[0017] Furthermore, the detection component is first connected to the main frame component via a connector. To ensure the stability of the detection component, a reinforcing plate is directly installed at the connector. This reinforcing plate with reinforcing ribs provides stable support to the main frame component, ensuring the overall stability of the detection component after installation via the quick-connect assembly. During installation, the trigger frame must first be pressed down so that the notch on the trigger frame aligns with the position on the main frame component. Then, the connector is connected to the main frame component. The trigger frame is then released and reset by a spring, allowing the reset trigger frame to rest against the main frame component, thus completing the quick-connect assembly's function of being quickly and securely fixed to the main frame component via the trigger frame.

Four sets of contact wheels 8 are rotatably installed at both ends of the contact frame 203. The main frame rod 201 is directly set as a long rod, which makes it easy to install various components on the main frame rod 201. The top bracket 202 is directly set on the main frame rod 201. The triangular top bracket 202 is convenient to cooperate with the top pressure assembly 3 in the future. It is easy to snap and install it on the main air duct 1 for use. The contact wheels 8 of the contact frame 203 can easily contact and fix with the curved wall of the main air duct 1.
[0040] Among them, such as Figure 3 Figure 5 As shown, the bottom slide 301 of the top pressing assembly 3 is triangular in shape, and an outer bracket 302 is snapped onto the outer end of the bottom slide 301. The bottom slide 301 with the outer bracket 302 is slidably mounted on the main frame assembly 2. First, the bottom slide 301 is set into a triangular shape, corresponding to the top bracket 202 of the main frame assembly 2. The bottom slide 301 is set to be snapped onto the main frame assembly 2 by the outer bracket 302, so that the bottom slide 301 can be easily installed and removed from the main frame assembly 2. The slidably mounted bottom slide 301 has a top bracket that pushes against the main frame assembly 2 after sliding during use. 202. The main air duct 1 is clamped together.

Six sets of contact wheels 8 are rotatably installed at both ends of the top pressure frame 303. The top pressure frame 303 is oscillatingly installed on the bottom slide 301. The top pressure frame 303 is set with an arc structure, so that the contact wheels 8 on the top pressure frame 303 can better contact the outer wall of the main air duct 1 through the arc structure, thereby stably achieving the effect of the top pressure frame 303 and the contact frame 203 of the main frame assembly 2 clamping the main air duct 1.
[0041] Among them, such as Figure 3 Figure 5As shown, the fixing sleeve 401 of the fixing component 4 is fitted onto the bottom of the main frame component 2. The fixing sleeve 401 is fixed to the outside by bolts. A horizontal support platform 402 is provided at the upper end of the fixing sleeve 401. A spring plate 403 is fixedly installed on the support platform 402. The top of the spring plate 403 is in contact with the top pressure component 3. First, to make the device easier to operate, the fixing sleeve 401 is directly fitted onto the bottom of the main frame component 2 and fixed with bolts. This makes it convenient to use the main frame component 2 by holding the fixing sleeve 401. The spring plate 403 is fixed on the horizontal support platform 402 on the fixing sleeve 401. The top of the spring plate 403 is in direct contact with the bottom of the top pressure component 3. At this time, the fixing component 4 can be directly held and then slid down to contact the top pressure component 3 to achieve sliding control of the top pressure component 3. When the top pressure component 3 is released, the top pressure component 3 will quickly rebound through the spring plate 403. At the same time, the spring plate 403 makes the top pressure component 3 and the main frame component 2 stably clamped onto the main air duct 1.
[0042] Among them, such as Figure 4 Figure 6 As shown, the detector 501 of the detection component 5 adopts a deepened structure. A snap-fit cover 502 is installed on the detector 501 facing the external fan 7. A barrier net 503 is provided on the snap-fit cover 502. The outer end face of the barrier net 503 is set as a sharp structure. In order to allow the detection component 5 to better detect the wind speed, the detector 501 is directly deepened to increase the contact area of the detector 501 blades. The barrier net 503 of the snap-fit cover 502 is set as a sharp shape so that the snap-fit cover 502 and the barrier net 503 can block larger debris, while the sharp barrier net 503 will not block the flow of air.
[0043] Among them, such as Figure 4 Figure 6As shown, the connector 601 of the quick-connect assembly 6 is located at the bottom of the detection assembly 5. The connector 601 is sleeved on the head of the main frame assembly 2. A reinforcing plate 602 is provided at the sleeve position of the connector 601. The reinforcing plate 602 is designed with an extended structure with reinforcing ribs. First, the detection assembly 5 is sleeved on the main frame assembly 2 through the connector 601.

When installing the quick-connect assembly 6, the trigger bracket 603 needs to be pressed first so that the notch of the trigger bracket 603 corresponds to the position of the main frame assembly 2. At this time, the connector 601 is sleeved on the main frame assembly 2. Then, the trigger bracket 603 is released and reset by the spring, so that the reset trigger bracket 603 presses against the main frame assembly 2, thus completing the function of the quick-connect assembly 6 to be quickly fixed on the main frame assembly 2 through the trigger bracket 603.
[0044] The working principle of this embodiment is as follows: During installation, the snap cover 502 of the detector 501 needs to be installed first. At this time, it is necessary to ensure that the sharp side of the barrier mesh 503 at the snap cover 502 faces outward. After selecting the detection component 5 of the specified size, press the trigger frame 603 at the bottom of the detection component 5 directly so that the connector 601 can be directly sleeved on the top of the main frame component 2. Then release the trigger frame 603 to make it spring back, and the quick installation of the detection component 5 through the quick connector 6 can be completed.
[0045] At this point, hold the fixing component 4 at the bottom of the main frame assembly 2 and slide it down to contact the protrusion at the outer end of the top pressure component 3, so that the top pressure component 3 is separated from part of the main frame assembly 2. Then place the space between the top pressure component 3 and the main frame assembly 2 at the main air duct 1, and then loosen the outside of the top pressure component 3 so that the top pressure component 3 rebounds through the spring plate 403, so that the contact wheel 8 of the top pressure component 3 and the main frame assembly 2 is stably clamped at the main air duct 1, which is convenient for subsequent device testing.
