Description

Technical Field

[0001] This utility model relates to the field of probe assembly technology, specifically to a gas quality detection probe assembly that is easy to adjust at multiple angles. Background Technology

[0002] Utility model patent CN209946008U discloses a gas detection probe. It includes a light transmission device, a fluorescence excitation device, and a light reflection device. The light transmission device is used for bidirectional light transmission. The fluorescence excitation device is connected to the light transmission device, receives the light output from the light transmission device, and comes into contact with a characteristic gas. The light reflection device is connected to the end of the fluorescence excitation device away from the light transmission device, and is used to reflect the excited fluorescence, which is then transmitted back to the light transmission device. Based on the gas-sensitive characteristics of fluorescent materials, the gas detection probe can detect changes in the concentration of characteristic gases caused by partial discharge, thereby determining the degree of damage to insulating materials. This gas detection probe enables long-term online detection of characteristic gases in power distribution systems, ensuring the safe operation of the power grid. The gas detection probe can also detect non-electrical partial discharges and has advantages such as simple structure, high reliability, electromagnetic insensitivity, and convenient installation.

[0003] However, the device has some shortcomings in use. The device is not easy to install and disassemble on the wall. Also, the probe position is fixed, making it difficult to adjust to multiple angles for detection. Utility Model Content

[0004] The purpose of this invention is to provide a gas quality detection probe assembly that is easy to adjust at multiple angles, which solves the problems of inconvenient installation and disassembly of the device on the wall, and the fixed position of the probe, which makes it difficult to adjust at multiple angles for detection.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a gas quality detection probe assembly that is easy to adjust at multiple angles, including a mounting plate, a fixing mechanism on the mounting plate, a support fixedly mounted on the right end of the mounting plate, a motor fixedly mounted on the upper end of the support, a rotating shaft of the motor passing through the support and rotatably connected to the support, a gear ring fixedly connected to the outside of the rotating shaft of the motor, an adjustment mechanism on the support, a support rod on the adjustment mechanism, and a probe fixedly mounted on the right end of the support rod.

[0006] Preferably, the fixing mechanism includes a cylinder, with the cylinder fixedly mounted on the left end of the mounting plate. A toothed plate is slidably connected inside the cylinder, and a wedge is fixedly connected to the surface of the toothed plate. The wedge and the cylinder are slidably connected, and a cone is in contact with the surface of the wedge. A screw is fixedly connected to the right end of the cone. A screw rod is mounted inside the mounting plate via a bearing, and the screw rod and the screw rod are connected by threads. By rotating the screw rod and the screw rod, the cone moves, causing it to press against the wedge. This causes the wedge to move the toothed plate, which then slides out of the cylinder, bringing the toothed plate into contact with the wall of the mounting hole and pressing it tightly. This facilitates installation of the device on the wall.

[0007] Preferably, a slide rod is fixedly connected to the surface of the screw cylinder, and the slide rod and the insert cylinder are slidably connected. The slide rod guides the movement of the screw cylinder.

[0008] Preferably, the adjustment mechanism includes a support shaft, which is rotatably connected to the inside of the support. A gear is fixedly connected to the outside of the support shaft, meshing with a gear ring. The gear is fixedly connected to the support rod, and a pressure ring is slidably connected to the outside of the support shaft. A spring is provided on the outside of the support shaft. The gear ring is driven by a motor to rotate, engaging with the gear, which in turn causes the support rod to move the probe. The spring acts on the pressure ring, causing the insert teeth to engage with the gear. This facilitates gear rotation and positioning, allowing for easy angle adjustment of the probe and subsequent positioning.

[0009] Preferably, a guide rod is fixedly connected to the upper end of the pressure ring, and the guide rod is slidably connected to the support. The guide rod guides the movement of the pressure ring.

[0010] Preferably, one end of the spring is fixedly connected to the support, and the other end of the spring is fixedly connected to the pressure ring. By providing the spring, the pressure ring can be easily reset.

[0011] Preferably, the lower end of the pressure ring is fixedly connected to a toothed bracket, which is slidably connected to the gear. The toothed bracket facilitates positioning of the gear after it rotates.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses the rotation of the screw and the screw barrel to make a threaded movement, which causes the cone head to move, which in turn causes the cone head to press against the inclined block, which in turn causes the inclined block to drive the toothed plate to move and slide out of the insert, which in turn causes the toothed plate to contact and press against the wall of the mounting hole, making the device easy to install on the wall.

[0014] 2. This utility model uses a motor to drive the gear ring to rotate and the gears to engage, which in turn causes the support rod to move the probe. The spring acts on the pressure ring, which causes the insert teeth to be inserted into the gear. This makes it easy to limit the position after the gear rotates, making it easy to adjust the angle of the probe and to limit the position after adjustment. Attached Figure Description

[0020] 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.

[0021] Please see Figures 1-2 A gas quality detection probe assembly that is easy to adjust at multiple angles includes a mounting plate 1, a fixing mechanism 2 on the mounting plate 1, a support 3 fixedly mounted on the right end of the mounting plate 1, a motor 4 fixedly mounted on the upper end of the support 3, the rotating shaft of the motor 4 passing through the support 3 and rotatably connected to the support 3, a gear ring 5 fixedly connected to the outside of the rotating shaft of the motor 4, an adjustment mechanism 6 on the support 3, a support rod 7 on the adjustment mechanism 6, and a probe 8 fixedly mounted on the right end of the support rod 7.

[0022] Please see Figures 1-3The fixing mechanism 2 includes a tube 21. The tube 21 is fixedly installed on the left end of the mounting plate 1. A toothed plate 22 is slidably connected inside the tube 21. An inclined block 23 is fixedly connected to the surface of the toothed plate 22. The inclined block 23 and the tube 21 are slidably connected. A cone 24 is in contact with the surface of the inclined block 23. A screw 25 is fixedly connected to the right end of the cone 24. A screw 26 is installed inside the mounting plate 1 through a bearing. The screw 26 and the screw 25 are connected by a thread. A sliding rod 27 is fixedly connected to the surface of the screw 25. The sliding rod 27 and the tube 21 are slidably connected. By setting the sliding rod 27, the movement of the screw 25 is guided. By rotating the screw 26 and the screw 25 to make threaded movement, the cone 24 moves, which in turn causes the cone 24 to press against the inclined block 23. This causes the inclined block 23 to drive the toothed plate 22 to move and slide out of the tube 21. This causes the toothed plate 22 to contact and press against the wall of the mounting hole, making the device easy to install on the wall.

[0023] Please see Figure 1 , Figure 2 , Figure 4 The adjusting mechanism 6 includes a support shaft 61, which is rotatably connected to the inside of the support 3. A gear 62 is fixedly connected to the outside of the support shaft 61, meshing with a gear ring 5. The gear 62 is also fixedly connected to a support rod 7. A pressure ring 63 is slidably connected to the outside of the support shaft 61, and a guide rod 64 is fixedly connected to the upper end of the pressure ring 63. The guide rod 64 is slidably connected to the support 3, guiding the movement of the pressure ring 63. A spring 65 is provided on the outside of the support shaft 61, with one end of the spring 65 fixedly connected to the support 3 and the other end fixedly connected to the pressure ring 63. The connection is achieved by setting a spring 65 to facilitate the reset of the pressure ring 63. The lower end of the pressure ring 63 is fixedly connected to a tooth 66, which is slidably connected to the gear 62. By setting the tooth 66, the gear 62 can be easily positioned after rotation. The motor 4 drives the gear ring 5 to rotate and cooperate with the gear 62, thereby causing the support rod 7 to move the probe 8. The spring 65 acts on the pressure ring 63, causing the tooth 66 to be inserted into the gear 62, thereby making it easy to limit the rotation of the gear 62. This makes it easy to adjust the angle of the probe 8 and to limit the position after adjustment.

[0024] The specific implementation process of this utility model is as follows: When installing the device, insert the cylinder 21 into the reserved hole in the wall. Manually rotate the screw 26. The rotation of the screw 26 and the screw cylinder 25 cause a threaded movement, which in turn moves the screw cylinder 25. The screw cylinder 25 drives the cone head 24 to move, causing the cone head 24 to press against the inclined block 23. This causes the inclined block 23 to move the toothed plate 22, making the toothed plate 22 abut and press against the wall of the reserved hole in the wall. By rotating the screw 26 and the screw cylinder 25 to cause a threaded movement, the cone head 24 moves, which in turn presses against the inclined block 23. This causes the inclined block 23 to move the toothed plate 22 and slide it out of the cylinder 21, thus making the toothed plate 22 slide against the mounting hole. The wall contact is tight, making the device easy to install on the wall. Start the motor 4, the motor 4 drives the gear ring 5 to rotate, the gear ring 5 rotates the gear 62, which in turn causes the support rod 7 to move the probe 8. The rotation of the gear 62 causes the insert tooth 66 and the slot on the gear 62 to misalign, which causes the insert tooth 66 to move upward. The insert tooth 66 drives the pressure ring 63 to move, the pressure ring 63 moves and squeezes the spring 65, which is then compressed until the gear 62 stops rotating. The spring 65 acts on the pressure ring 63, which allows the insert tooth 66 to be inserted into the gear 62. This makes it easier for the gear 62 to be limited after rotation, making it easier to adjust the angle of the probe 8 and to limit it after adjustment.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
