Description

Technical Field

[0001] The invention relates to the field of air conditioning detection, in particular to a fault detection device based on recycling refrigeration effect of a central air conditioner. Background Art

[0002] Central air conditioners are composed of an outdoor unit and an indoor unit. The heat exchanger in the outdoor unit is called a condenser, and the heat exchanger in the indoor unit is called an evaporator. The condenser exchanges heat between the high-temperature and high-pressure gaseous Freon and the air outdoors, turning it into low-temperature and high-pressure liquid Freon for cooling. When the cooling effect of the central air conditioner fails, mainly check the condenser of the air conditioner and pay attention to whether there is any refrigerant leakage.

[0034] When the rotating ring 6 is sleeved on the outer side of the condenser tube, the outer side of the condenser tube pushes the cleaning roller 27 to move, so that the cleaning roller 27 pushes the sealing cover 25 to move through the roller rod 26, and the sealing cover 25 pushes the installation box 24 to move, so that the installation box 24 pushes the four support rods 22 to move, and the support rods 22 stretch the tension spring 23 through the sliding column 21, and the elasticity of the tension spring 23 can be used to make the cleaning roller 27 press against the outer side of the condenser tube. When the rotating ring 6 rotates, the support rod 22 is driven to rotate synchronously through the plug plate 17, so that the cleaning roller 27 can roll along the outer side of the condenser tube to clean the floating dust on the outer side of the condenser tube, and with the rotation of the cleaning roller 27, the scraper strip 28 scrapes the floating dust stuck on the outer side of the cleaning roller 27 into the installation box 24 to store the floating dust, so that the cleaning roller 27 can continuously clean the condenser tube to prevent the floating dust from affecting the detection effect of the probe 7, thereby achieving the effect of improving the detection accuracy, and after the detection, the user can open the sealing cover 25 to clean the dust accumulated in the installation box 24.

The mounting bars 1 30 and the mounting bars 2 31 are fixedly installed on the outer side of the support bars 29. There are four mounting bars 1 30 and one mounting bar 2 31 on the two support bars 29 respectively. The ends of the mounting bars 1 30 and the mounting bars 2 31 away from the support bars 29 are fixedly connected with U-shaped frames 32. The inner side of the U-shaped frame 32 is limited and slidable with a slide bar 33. The end of the slide bar 33 away from the support bar 29 is an arc structure, which is convenient for cold The outer sides of the condensation tube are attached to each other, and two symmetrically distributed sliders 34 are fixedly connected to the outer side of the slide bar 33. A long groove for limiting the sliding of the slider 34 is provided on the outer side of the U-shaped frame 32 to provide a guide for the movement of the slide bar 33. A slide bar 35 is fixedly connected to the inner side of the U-shaped frame 32. A side of the slide bar 33 close to the support bar 29 is provided with an insertion cavity for limiting the sliding of the slide bar 35. A spring 36 is fixedly connected between the slide bar 33 and the inner side of the U-shaped frame 32.

A ball 37 is rotatably installed on the end of the slide bar 33 away from the slide bar 35 to facilitate the movement of the slide bar 33 along the outer side of the condensation tube.

[0036] When the rotating ring 6 is sleeved on the outside of the condenser, the outside of the condenser contacts the arc surface of the slide bar 33, pushing the insertion cavity on the slide bar 33 to move along the outside of the slide rod 35, and driving the slider 34 to move along the long groove of the U-shaped frame 32, compressing the spring 36, and utilizing the elasticity of the spring 36 to make the ball 37 on the slide bar 33 press against the outside of the condenser, so that the ball 37 can roll along the outside of the condenser. Thus, the condenser is positioned at multiple points by using the slide bar 33 on the mounting bar 1 30 and the slide bar 33 on the mounting bar 2 31, so that the center of the rotating ring 6 is aligned with the center of the condenser, and the elasticity of the spring 36 is utilized to facilitate positioning of condensers of more sizes, so that the distance between the probe 7 and the condenser is kept consistent during rotation, thereby providing protection for the probe 7, thereby achieving a smooth and safe detection effect.

[0037] Working principle: First, the user aligns the positioning ring 2 with the opening on the rotating ring 6, and puts the positioning ring 2 and the rotating ring 6 on the outside of the condenser, so that the outside of the condenser pushes the arc surface of the slide bar 33 and the outside of the cleaning roller 27 to move, and the insertion cavity on the slide bar 33 moves along the outside of the slide rod 35, and drives the slider 34 to move along the long groove of the U-shaped frame 32, compresses the spring 36, and uses the elasticity of the spring 36 to make the ball 37 on the slide bar 33 press against the outside of the condenser, and the condenser is positioned at multiple points through the slide bar 33 on the mounting bar 1 30 and the slide bar 33 on the mounting bar 2 31. At the same time, the cleaning roller 27 pushes the sealing cover 25 to move through the roller rod 26, so that the sealing cover 25 pushes the installation box 24 to move, and the installation box 24 pushes the four support rods 22 to move along the inner side of the sleeve 20, and the support rod 22 drives the slide column 21 to stretch the tension spring 23, and uses the elasticity of the tension spring 23 to make the cleaning roller 27 press against the outside of the condenser, and then, the user controls the control panel 1 The motor 12 and the probe 7 are started. The motor 12 drives the corresponding rotating rod 9 to rotate through the synchronous belt 2 13. The rotating rod 9 drives the other two rotating rods 9 to rotate synchronously through the synchronous belt 1 11. The three rotating rods 9 drive the corresponding gears 10 to rotate synchronously, so that the gear 10 drives the rotating ring 6 to rotate along the inner ring of the positioning ring 2 through the arc rack 8. The rotating ring 6 drives the support rod 22 to rotate synchronously through the plug plate 17, so that the cleaning roller 27 rolls along the outer side of the condenser tube to clean the floating dust on the outer side of the condenser tube. With the rotation of the cleaning roller 27, the scraper strip 28 scrapes the floating dust stuck on the outer side of the cleaning roller 27 into the installation box 24 to store the floating dust. Finally, the rotating ring 6 drives the probe 7 to detect the outer side of the condenser tube for one circle. When a leakage point is detected, the detection information is transmitted to the control panel 15 through the Bluetooth receiving head 16 for recording and prompting. The user can find the leakage point of the condenser tube, thereby performing a comprehensive detection of the condenser tube and improving the detection accuracy.

The outer side of the vertical plates 41 and the top of the mounting plate 40 are provided with mounting holes, which facilitates the multi-angle installation of the supporting equipment.

[0041] In this embodiment: the user installs and fixes the supporting device through the mounting holes on the mounting plate 40 or the vertical plate 41, so that the supporting device can be installed at different angles according to the installation conditions of the condenser, and the swivel 6 can be put on the condenser.

[0042] Example 4: Please refer to Figure 3-Figure 5 This embodiment further illustrates other embodiments. The inner side of the device housing 1 shown in the figure is fixedly connected with two shaping strips 42 which are symmetrically distributed between the three rotating rods 9. The outer side of the shaping strip 42 contacts the inner side of the synchronous belt 11 to improve the stability of the synchronous belt 11 during rotation. The outer side of the arc strip 14 and the two ends of the sliding cavity on the rotating ring 6 are both arc structures, which facilitates the insertion of the arc strip 14 into the sliding cavity on the rotating ring 6.

[0043] In this embodiment: when the synchronous belt 11 rotates, it can rotate along the outer side of the shaping strip 42, so that the synchronous belt 11 can transmit the power to the three rotating rods 9 in an arc shape, thereby improving the stability of the rotation of the synchronous belt 11, and when the rotating ring 6 rotates, it can align with the arc strip 14 through the arc surfaces at both ends of the sliding cavity, so as to facilitate the accurate insertion of the arc strip 14 into the sliding cavity on the rotating ring 6.
