Description

Technical Field

[0001] This utility model relates to the technical field of wind pressure monitoring equipment, specifically a wind pressure monitoring device for fan pipelines. Background Technology

[0002] A fan is a device that drives gas flow through mechanical energy. It is widely used in ventilation, cooling, gas transportation, combustion air supply, industrial dust removal and other fields. In order to ensure the normal operation of ventilation equipment, improve efficiency, ensure safety and meet regulatory requirements, it is necessary to use wind pressure sensors to monitor the wind speed in the fan duct, ensure the safe operation of the system, optimize system performance, extend equipment life, meet regulatory requirements, and provide support for data analysis.

[0003] Currently, wind pressure sensors are usually fixed to pipes with bolts. Although the installation is simple and convenient, in order to ensure accurate monitoring of wind pressure in the pipe, the wind pressure sensor needs to be maintained regularly. When maintaining the wind pressure sensor, it needs to be removed from the pipe. Each time the wind pressure sensor is removed and installed, it will damage the threads on the pipe, which will lead to instability after the wind pressure sensor is installed later. Utility Model Content

[0004] The purpose of this invention is to provide a wind pressure monitoring device for fan pipelines to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A wind pressure monitoring device for a fan duct includes a mounting plate. Fixing mechanisms are provided on both sides of the front of the mounting plate. A wind pressure sensor body is detachably connected between the two fixing mechanisms. A strap for fixing the wind pressure sensor body to the duct is provided on the back of the mounting plate.

[0007] The fixing mechanism includes an inverted bracket frame disposed on the front of the mounting plate. The front of the inverted bracket frame is provided with a connector. The inverted bracket frame is fixedly connected to the mounting plate by two symmetrical connectors that engage with the connectors at corresponding positions.

[0008] Furthermore, the front of the U-shaped card frame is provided with a through hole corresponding to the card connector, and the connector includes two symmetrical inserts that are respectively inserted into the through holes at corresponding positions and engaged with the card connectors at corresponding positions.

The outer wall of the fixing cylinder is fixedly connected with a plurality of cylindrical sleeves communicating with the inside of the fixing cylinder at the corresponding position, and the inside of the cylindrical sleeves is fixedly connected with spring steel balls that engage with the spherical grooves at the corresponding positions.

[0010] Furthermore, a connecting plate is fixedly connected between the two inserts at opposite positions, and a compression spring is fixedly connected between the connecting plate and the corresponding U-shaped frame and located outside the insert.

[0011] Furthermore, a rectangular frame is fixedly connected to one side of the back of the mounting plate, and two symmetrical hooks are fixedly connected to the other side of the back of the mounting plate. Both ends of the strap are fixedly connected to connecting posts, one of which is rotatably connected between the two ends inside the rectangular frame, and the other connecting post is engaged between the two hooks.

[0023] 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.

[0024] Please see Figure 1 - Figure 6 In this embodiment of the utility model, a wind pressure monitoring device for a fan duct includes a mounting plate 1. Fixing mechanisms 2 are provided on both sides of the front of the mounting plate 1. A wind pressure sensor body 3 is detachably connected between the two fixing mechanisms 2. A strap 4 for fixing the wind pressure sensor body 3 to the duct is provided on the back of the mounting plate 1. The fixing mechanism 2 includes an U-shaped clip frame 21 provided on the front of the mounting plate 1. A connector is provided on the front of the U-shaped clip frame 21. Two symmetrical connectors that engage with the connectors at corresponding positions are fixedly connected between the U-shaped clip frame 21 and the mounting plate 1.

[0025] Specifically, first, insert the wind pressure sensor body 3 between the two U-shaped clips 21 (currently, the wind pressure sensor body 3 usually has fixing tubes installed on both sides, and the fixing blocks have insertion holes). Then, by pressing the two connectors firmly, the connectors pass through the insertion holes on the fixing blocks and engage with the two clips at the corresponding positions, thus fixing the wind pressure sensor body 3 to the front of the mounting plate 1. Then, use the straps 4 to fix the mounting plate 1 to the pipeline where the wind pressure needs to be monitored. The wind pressure sensor body 3 can monitor the wind pressure in the pipeline in real time through its operation (how the wind pressure sensor body 3 monitors the pipeline). The internal wind pressure (this is existing technology and will not be elaborated here) When it is necessary to disassemble the wind pressure sensor body 3 for maintenance, the two plugs can be pulled out forcefully to release the wind pressure sensor body 3 from its limit. Then the wind pressure sensor body 3 can be taken out from the two U-shaped clip frames 21. This device can achieve quick disassembly and assembly of the wind pressure sensor body 3 through the cooperation of the U-shaped clip frames 21, plugs and clips. Moreover, by fixing the wind pressure sensor body 3 to the pipeline with the strap 4, drilling holes in the pipeline can be avoided, preventing damage to the internal threads during repeated disassembly and assembly of the wind pressure sensor body 3.

[0026] Example 1

[0027] like Figure 3 and Figure 4 As shown, in this embodiment, the front of the U-shaped card frame 21 has a through hole corresponding to the snap-fit ​​part. The snap-fit ​​part includes two symmetrical pins 22 that are inserted into the through holes at corresponding positions and snap-fitted with the snap-fit ​​parts at corresponding positions. One end of the outer wall of the pin 22 has a plurality of spherical grooves 23 at equal angles. The snap-fit ​​part includes a fixing cylinder 24 fixedly connected to the back of the U-shaped card frame 21 at the corresponding position. The outer wall of the fixing cylinder 24 is fixedly connected to a plurality of cylindrical sleeves 25 that communicate with the interior of the fixing cylinder 24 at the corresponding position. The interior of the cylindrical sleeves 25 is fixedly connected to spring steel balls 26 that snap-fitted with the spherical grooves 23 at the corresponding position. A connecting plate 27 is fixedly connected between the two pins 22 at opposite positions. A compression spring 28 is fixedly connected between the connecting plate 27 and the U-shaped card frame 21 at the corresponding position and located outside the pin 22.

[0028] In this embodiment, by passing the insertion post 22 through the through hole and the insertion hole on the fixing block, and inserting it into the fixing cylinder 24 at the corresponding position, when the insertion post 22 is inserted into the fixing cylinder 24, multiple spring steel balls 26 on the outside of the fixing cylinder 24 are squeezed by the insertion post 22 and retracted into the cylindrical sleeve 25 at the corresponding position until the spherical groove 23 on the insertion post 22 aligns with the spring steel balls 26. At this time, the spring steel balls 26 are engaged with the spherical groove 23 at the corresponding position, and under the action of the two compression springs 28, the insertion post 22 can be engaged. Limiting is performed to fix the wind pressure sensor body 3 (if there is a gap between the fixing blocks on both sides of the wind pressure sensor body 3 and the C-shaped frame 21, anti-slip pads can be fixed on the inside of the C-shaped frame 21 with glue). When it is necessary to remove the wind pressure sensor body 3 from the front of the mounting plate 1, the connecting plate 27 can be pulled to separate the two inserts 22 from the C-shaped frame 21 and the wind pressure sensor body 3, and then the wind pressure sensor body 3 can be taken out from the two C-shaped frames 21.

[0029] Example 2

[0030] like Figure 2 , Figure 5 and Figure 6 As shown, in this embodiment, a rectangular frame 11 is fixedly connected to one side of the back of the mounting plate 1, and two symmetrical hooks 12 are fixedly connected to the other side of the back of the mounting plate 1. Both ends of the strap 4 are fixedly connected to connecting posts 41. One connecting post 41 is rotatably connected between the two ends inside the rectangular frame 11, and the other connecting post 41 is engaged between the two hooks 12. The top of the connecting post 41 located at the rectangular frame 11 passes through the rectangular frame 11 and is fixedly connected to a worm gear 42. A worm 43 that meshes with the worm gear 42 passes through the front of the mounting plate 1. A rubber pad 13 is fixedly connected to the back of the mounting plate 1.

[0031] In this embodiment, by stretching the strap 4 and wrapping the fan duct between the strap 4 and the wind pressure sensor body 3, and then clamping another connecting post 41 between the two hooks 12, the rotation of the worm gear 43 can cause the worm wheel 42 to drive one of the connecting posts 41 to rotate, thereby winding up the strap 4 and making the strap 4 taut to fix the mounting plate 1 to the outside of the duct.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
