[0002] A fan coil unit is a common terminal device of an air conditioner, mainly used for adjusting the temperature and humidity of indoor air. It is widely used in buildings such as hotels, office buildings, hospitals, and schools to provide a comfortable indoor environment. The fan coil unit consists of a fan and a heat exchange coil, and controls the indoor temperature and humidity by circulating air.

[0003] For example, the Chinese patent discloses: a device for detecting the noise of a fan coil unit, patent number: CN213455840U. Through the setting of a first noise detector, a second noise detector and a vibration detector, when in use, the first noise detector and the second noise detector are used to detect the noise inside the coil and the fan, and then the vibration detector is used to collect data on the vibration when the air flows inside the coil, so that the device for detecting the noise of the fan coil unit has the effect of not only being able to detect noise, but also being able to detect the vibration inside the coil, achieving double detection and improving the accuracy of data.

[0004] However, in the process of implementing the above technical solution, it is found that there are at least the following technical problems: the above device detects the noise of the fan coil unit by installing two noise detectors, but the two noise detectors in the above device are relatively fixedly installed, lacking a displacement function, which limits its detection range and flexibility, and when detecting by installing multiple noise detectors, multiple detectors need to be synchronously calibrated before each detection, and the operation is relatively cumbersome. Summary of the Utility Model

[0005] (1) Technical Problems to be Solved

[0006] In view of the deficiencies of the prior art, the utility model provides a device for detecting the performance and noise of a fan coil unit, and solves the technical problems that the above device detects the noise of the fan coil unit by installing two noise detectors, but the two noise detectors in the above device are relatively fixedly installed, lacking a displacement function, which limits its detection range and flexibility, and when detecting by installing multiple noise detectors, multiple detectors need to be synchronously calibrated before each detection, and the operation is relatively cumbersome.

[0007] (2) Technical Solutions

[0008] To achieve the above purposes, the utility model is realized through the following technical solutions:

[0009] A fan coil unit performance and noise detection device comprises a detection platform, a mounting seat is slidably connected inside the detection platform, a rotating shaft is rotatably connected inside the mounting seat, a pressing block is sleeved on the outer surface of the rotating shaft, a spring is sleeved inside the mounting seat, the spring is sleeved on the outer surface of the pressing block, a clamping block is fixedly connected to the lower end of the pressing block, a noise detector body is clamped on the upper end of the mounting seat, a limiting mechanism is arranged inside the detection platform, the limiting mechanism comprises a clamping slot, and the clamping slot is arranged inside the detection platform.

[0010] Preferably: a placement groove is provided inside the testing platform.

[0014] Preferably, a rubber pad is sleeved on the outer surface of the clamping block.

[0015] (III) Beneficial effects

[0016] 1. When it is necessary to use the noise detector body to detect noise, the pressing block can be pressed to rotate it with the rotating shaft as the center. The rotation of the rotating shaft drives the card block to extend from the card slot. At this time, the pressing block loses its limit, and the mounting seat can be pushed to slide to drive the noise detector body to adjust its placement position. After sliding to the desired position, the pressing block is released, and the pressing block is squeezed and rotated to reset under the action of the spring. At this time, the card block rotates to the card slot for limit to ensure the stability of the placement of the noise detector body during noise testing. By pressing the pressing block to drive the noise detector body to adjust its placement position, noise can be detected from different positions to avoid the situation where multiple noise detector bodies need to be used for detection due to the fixed placement of the noise detector body and the inability to move. This is beneficial to improving the convenience and flexibility of the detection process.

[0017] 2. After the fan coil unit body is placed in the placement slot, start the cylinder, and the cylinder output shaft lifts the slider upward to slide in the test bench. During the sliding process of the slider, the connecting rod is pushed to rotate, and the T-block is pushed to rotate through the squeezing of the connecting rod. The rotation of the T-block drives the clamping block to clamp on the outer surface of the fan coil unit body to fix it, so as to ensure the stable placement of the fan coil unit body during the test, thereby providing a more stable and controllable test environment.

Specific implementation manner

[0024] In the embodiment of the present application, by providing a fan coil performance and noise detection device, it effectively solves the problem that the above device detects the noise of the fan coil by installing two noise detectors. However, the two noise detectors in the above device are relatively fixed in installation and lack a displacement function, which limits its detection range and flexibility. Moreover, when detecting by installing multiple noise detectors, multiple detectors need to be synchronously calibrated before each detection, and the operation is relatively cumbersome. When it is necessary to use the noise detector body to detect noise, the pressing block can be pressed to rotate it around the rotating shaft. The rotation of the rotating shaft drives the clamping block to extend out of the card slot. At this time, the pressing block loses its limit and can push the mounting seat to slide to drive the noise detector body to adjust the placement position. After sliding to the required position, release the pressing block, and under the action of the spring, the pressing block is squeezed to rotate and reset. At this time, the clamping block rotates into the card slot for limiting to ensure the stability of the placement of the noise detector body during the noise test. By pressing the pressing block to drive the noise detector body to adjust the placement position, the noise can be detected from different positions, avoiding the situation that multiple noise detector bodies need to be used for detection because the noise detector body is fixedly placed and cannot be moved, which is beneficial to improving the convenience and flexibility in the detection process.

[0025] Embodiment

[0026] Such as Figure 1 、 Figure 2 、 Figure 3 And Figure 4As shown in the figure, the technical solution in the embodiment of the present application effectively solves the technical problem that the above device detects the noise of the fan coil unit by installing two noise detectors. However, the two noise detectors in the above device are relatively fixed in installation and lack a displacement function, which limits their detection range and flexibility. Moreover, when detecting by installing multiple noise detectors, multiple detectors need to be synchronously calibrated before each detection, and the operation is relatively cumbersome. The general idea is as follows: A device for detecting the performance and noise of a fan coil unit includes a detection table 11. A mounting seat 12 is slidably connected inside the detection table 11. A rotating shaft 13 is rotatably connected inside the mounting seat 12. A pressing block 14 is sleeved on the outer surface of the rotating shaft 13. A spring 15 is sleeved inside the mounting seat 12, and the spring 15 is sleeved on the outer surface of the pressing block 14. A clamping block 16 is fixedly connected to the lower end of the pressing block 14. A noise detector body 17 is clamped at the upper end of the mounting seat 12. A limiting mechanism is provided inside the detection table 11. The limiting mechanism includes a clamping groove 18 opened inside the detection table 11. The clamping block 16 is adapted to the clamping groove 18. When it is necessary to use the noise detector body 17 to detect noise, the pressing block 14 can be pressed to rotate around the rotating shaft 13. The rotation of the rotating shaft 13 drives the clamping block 16 to extend out of the clamping groove 18. At this time, the pressing block 14 loses its limit, and the mounting seat 12 can be pushed to slide to drive the noise detector body 17 to adjust the placement position. After sliding to the required position, the pressing block 14 is released. Under the action of the spring 15, the pressing block 14 is squeezed to rotate and reset. At this time, the clamping block 16 rotates into the clamping groove 18 for limiting to ensure the stability of the placement of the noise detector body 17 during the noise test. By pressing the pressing block 14 to drive the noise detector body 17 to adjust the placement position, the noise can be detected from different positions, avoiding the situation where multiple noise detector bodies 17 need to be used for detection due to the fixed placement of the noise detector body 17 and being unable to move, which is beneficial to improving the convenience and flexibility during the detection process.

[0027] A placement groove 19 is opened inside the detection table 11. A fan coil unit body 21 is movably connected inside the placement groove 19. The fan coil unit body 21 is carried and placed in the placement groove 19. The fan coil unit body 21 is connected to the cold and heat source system and the fan coil unit body 21 is started to confirm the normal operation of the fan coil unit body 21. The fan coil unit body 21 is set at a specified temperature and compared with the test environment temperature to detect its performance. The noise is detected by the noise detector body 17 sliding on the detection table 11.

[0028] The lower end of the detection table 11 is fixedly connected to a cylinder 22, and a slider 23 is sleeved on the outer surface of the cylinder 22. The slider 23 is slidably connected to the inside of the detection table 11. A connecting rod 24 is rotatably connected to the inside of the slider 23. A T-shaped block 25 is rotatably connected to the inside of the detection table 11. The connecting rod 24 is rotatably connected to the inside of the T-shaped block 25. A clamping block 26 is fixedly connected to the upper end of the T-shaped block 25. A rubber pad 27 is sleeved on the outer surface of the clamping block 26. The rubber pad 27 is clamped on the outer surface of the fan coil body 21. After the fan coil body 21 is placed in the placement groove 19, the cylinder 22 is started, and the cylinder The slider 23 is lifted upward on the output shaft 22 and slides in the test table 11. During the sliding process of the slider 23, the connecting rod 24 is pushed to rotate, and the T-block 25 is pushed to rotate by the squeezing of the connecting rod 24. The rotation of the T-block 25 drives the clamping block 26 to clamp on the outer surface of the fan coil body 21 to fix it, so as to ensure the stable placement of the fan coil body 21 during the test, thereby providing a more stable and controllable test environment. The outer sleeve of the clamping block 26 is connected with a rubber pad 27. When clamping and fixing, the rubber pad 27 contacts the surface of the fan coil body 21 to avoid damage to it.

[0029] In view of the problems existing in the prior art, the utility model provides a fan coil performance and noise detection device. When the noise detector body 17 needs to be used to detect the noise, the pressing block 14 can be pressed to rotate with the rotating shaft 13 as the center. The rotation of the rotating shaft 13 drives the clamping block 16 to extend from the clamping slot 18. At this time, the pressing block 14 loses its limit, and the mounting seat 12 can be pushed to slide to drive the noise detector body 17 to adjust the placement position. After sliding to the required position, the pressing block 14 is released, and the pressing block 14 is squeezed and rotated and reset under the action of the spring 15. At this time, the clamping block 16 rotates to the clamping slot 18 for limit, so as to ensure the stability of the placement of the noise detector body 17 during the noise test. By pressing the pressing block 14 to drive the noise detector body 17 to adjust the placement position, the noise can be detected from different positions, avoiding the situation where the noise detector body 17 is fixed and cannot be moved, resulting in the need to use multiple noise detector bodies 17 for detection, which is conducive to improving the convenience and flexibility of the detection process.

[0030] Working principle:

[0031] The first step is to carry the fan coil unit body 21 and place it in the placement slot 19, connect the fan coil unit body 21 to the cold and hot source system and start the fan coil unit body 21 to confirm that the fan coil unit body 21 is operating normally, set the fan coil unit body 21 to a specified temperature and compare it with the test environment temperature to detect its performance, and detect its noise through the noise detector body 17 sliding on the test table 11. After the fan coil unit body 21 is placed in the placement slot 19, start the cylinder 22, and the output shaft of the cylinder 22 lifts the slider 2 upward. The slider 23 slides in the testing table 11. The slider 23 pushes the connecting rod 24 to rotate during the sliding process. The connecting rod 24 squeezes and pushes the T-shaped block 25 to rotate. The rotation of the T-shaped block 25 drives the clamping block 26 to clamp on the outer surface of the fan coil body 21 to fix it, so as to ensure the stable placement of the fan coil body 21 during the test process, thereby providing a more stable and controllable test environment. The outer cover of the clamping block 26 is connected with a rubber pad 27. When clamping and fixing, the rubber pad 27 contacts the surface of the fan coil body 21 to avoid damage to the fan coil body 21.

[0032] In the second step, when the noise detector body 17 needs to be used to detect noise, the pressing block 14 can be pressed to rotate it with the rotating shaft 13 as the center. The rotation of the rotating shaft 13 drives the card block 16 to extend out of the card slot 18. At this time, the pressing block 14 loses its limit and can push the mounting seat 12 to slide to drive the noise detector body 17 to adjust its placement position. After sliding to the desired position, the pressing block 14 is released, and the pressing block 14 is squeezed and rotated to reset under the action of the spring 15. At this time, the card block 16 rotates to the card slot 18 for limiting to ensure the stable placement of the noise detector body 17 during noise testing. By pressing the pressing block 14 to drive the noise detector body 17 to adjust its placement position, noise can be detected from different positions to avoid the situation where the noise detector body 17 is fixed and cannot be moved, resulting in the need to use multiple noise detector bodies 17 for detection, which is beneficial to improving the convenience and flexibility of the detection process.

For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
