[0056] It should be understood that the terms such as "having", "comprising" and "including" used herein do not exclude the presence or addition of one or more other elements or their combinations.

[0057] As Figures 1-6 shown, the present invention provides a detection device for the refrigerating capacity of a chiller, including:

[0058] A housing 1, with a water inlet 9 and a water outlet 8 provided on both sides of the housing 1. A detection device 2 is provided between the water inlet 9 and the water outlet 8. A heating pipe 3 is sleeved on the detection device 2. Both the heating pipe 3 and the detection device 2 are electrically connected to a controller.

[0059] The working principle of the above technical solution: During actual use, connect the output end of the chiller to the water inlet 9 through a pipeline, then introduce the cold water of the chiller into the detection device, and at the same time determine the initial heating power of the heating pipe 3 according to the refrigerating capacity of the chiller. Then adjust the heating power of the heating pipe 3 according to the detection result of the detection device 2. When the detection result of the detection device 2 is determined, the heating power of the heating pipe 3 is equal to the actual refrigerating power of the chiller.

[0060] Beneficial effects of the above technical solution: Through the design of the above structure, by introducing the cold water in the chiller into the detection device, the refrigerating capacity of the chiller is measured through the cooperation of the internal detection device 2 and the heating pipe 3, avoiding the disassembly of the chiller and eliminating the need for manual intervention, thus saving productivity.

[0061] In one embodiment, the detection device 2 includes:

[0062] A detection pipe 4, which is arranged in the housing 1, and both ends of the detection pipe 4 are respectively connected to the water inlet 9 and the water outlet 8, and the heating pipe 3 is sleeved on the detection pipe 4;

[0066] Working principle and beneficial effects of the above technical solution: During actual use, before introducing the cold water of the chiller, start the three temperature sensors. When the values of the three temperature sensors are not much different, inject cold water into the detection device 2, and at the same time start the heating pipe 3. Adjust the heating power of the heating pipe 3 according to the average value of the values of the three temperature sensors until the average value of the three temperature sensors does not change within a preset time. At this time, the heating power of the heating pipe 3 is equal to the refrigerating power of the chiller.

[0072] A receiving groove 11 is provided on the inner wall of the water outlet 8;

[0073] A first fixing block 12 is provided on the inner wall of the water inlet 9;

[0074] A second fixing block 13 is provided on the inner wall of the water inlet 9;

[0075] A servo motor 19 is provided on the inner wall of the receiving groove 11, and the servo motor 19 is electrically connected to a controller;

[0077] A fixing rod 14, one end of the fixing rod 14 is connected to the inner wall of the receiving groove 11, the other end of the fixing rod 14 is connected to the first fixing block 12, and a plurality of arc-shaped blocks 15 are evenly provided on the fixing rod 14;

[0078] A cleaning block 16 is threadedly sleeved on the threaded rod 18, an airbag hole 21 is provided on the cleaning block 16, the fixing rod 14 passes through the airbag hole 21, and a first airbag 22 is provided in the airbag hole 21;

[0079] A sealing plate 17 is slidably sleeved on the threaded rod 18, the fixing rod 14 passes through the sealing plate 17, and the fixing rod 14 is slidably connected to the sealing plate 17;

[0080] A winding cavity 29 is provided in the cleaning block 16, a first rotating rod 32 is rotatably provided in the winding cavity 29, a wire reel 30 is sleeved on the first rotating rod 32, and a torsion spring 31 is provided between the wire reel 30 and the inner wall of the winding cavity 29;

[0081] A connecting rope 20, one end of the connecting rope 20 is connected to the wire reel 30, and the other end of the connecting rope 20 is connected to the sealing plate 17;

[0082] A cleaning ring 24 is slidably sleeved on the cleaning block 16;

[0083] A sliding groove 25 is provided on the outer wall of the cleaning block 16, a second airbag 27 is fixedly provided in the sliding groove 25, and the second airbag 27 is communicated with the first airbag 22 through a pipeline 23;

[0084] Slider 26, one end of the slider 26 is fixedly connected to the inner wall of the cleaning ring 24, and the other end of the slider 26 is slidably connected to the sliding groove 25;

[0085] First spring 28, the first spring 28 is sleeved on the second airbag 27, and the first spring 28 is arranged between the slider 26 and the inner wall of the sliding groove 25;

[0086] Locking block 54, the locking block 54 is arranged on the inner wall of the water outlet 8.

[0087] Working principle of the above technical solution: During actual use, after the detection is completed, the servo motor 19 is started, the servo motor 19 drives the threaded rod 18 to rotate, and the threaded rod 18 drives the cleaning block 16 to move away from the servo motor 19 through the thread. During the movement, the cleaning block 16 drives the cleaning ring 24 into the detection tube 4. After the cleaning block 16 enters the detection tube 4, when the arc-shaped block 15 passes through the airbag hole 21, the arc-shaped block 15 will drive the first airbag 22 to compress, so that the gas in the first airbag 22 enters the second airbag 27 through the pipeline 23, causing the second airbag 27 to expand, thereby pushing the slider 26 to drive the cleaning ring 24 to rotate. After an arc-shaped block passes through the airbag hole 21, under the action of the first spring 28, the slider 26 drives the cleaning ring 24 to rotate in the opposite direction, so that the cleaning ring 24 rotates back and forth when it is in the detection tube 4 to clean the inside of the detection tube; after the cleaning is completed, the servo motor 19 continues to drive the cleaning block 16 to move away from the servo motor 19 until the cleaning block 16 contacts the first fixed block 12 and the second fixed block 13. During this process, the cleaning block 16 drives the sealing plate 17 to move away from the servo motor 19 through the connecting rope 20 until the sealing plate 17 abuts against the locking block 54, thereby closing the detection tube 4.

[0088] Beneficial effects of the above technical solution: Through the design of the above structure, after the detection equipment completes the detection, the cleaning ring 24 of the provided sealing device 10 is used to clean the scale on the inner wall of the detection tube 4, avoiding the accumulation of scale from affecting the contact between the cold water and the detection tube 4 and reducing the measurement accuracy of the detection equipment during the next measurement; and the cleaning ring 24 will rotate reciprocally during the cleaning process, improving the cleaning effect of the sealing device 10; at the same time, after the cleaning is completed, the detection tube 4 is sealed and maintained by the sealing device 10 to prevent external dust from entering and affecting the next measurement, and at the same time isolating the air from entering to prevent the inner wall of the detection tube 4 from rusting and affecting the measurement accuracy, and at the same time improving the service life of the detection equipment.

[0089] In one embodiment, a monitoring device 33 is further provided in the housing 1, and the monitoring device 33 includes:

[0090] The first via hole 38 is provided on the cleaning block 16, and the first via hole 38 is located above the winding cavity 29;

[0091] The motor cavity 45 is provided on the cleaning block 16. The motor cavity 45 is located on one side of the first via hole 38. A dehumidifying motor 46 is further provided in the motor cavity 45, and the dehumidifying motor 46 is electrically connected to the controller;

[0092] One end of the second rotating rod 39 is connected to the dehumidifying motor 46, and the other end of the second rotating rod 39 extends into the first via hole 38 and is connected to a plurality of blades 40;

[0093] The speed measurement sensor 47 is provided on the inner wall of the motor cavity 45, and the speed measurement sensor 47 is electrically connected to the controller;

[0094] The first shielding groove 42 is provided on the inner wall of the first via hole 38. A first electromagnet 44 is provided in the first shielding groove 42. A first shielding plate 41 is slidably connected in the first shielding groove 42. A second spring 43 is provided between the first shielding plate 41 and the first electromagnet 44;

[0095] The measurement groove 34 is provided on the side of the cleaning block 16 away from the sealing plate 17. A pressure sensor 35 is provided at the top end of the inner wall of the measurement groove 34, and the pressure sensor 35 is electrically connected to the controller;

[0096] The floating block 36 is slidably connected to the measurement groove 34 through a connecting block 37;

[0097] The second via hole 48 is provided on the sealing plate 17. A second shielding groove 49 is provided on the inner wall of the second via hole 48. A second electromagnet 52 is provided in the second shielding groove 49, and the second electromagnet 52 is electrically connected to the controller;

[0099] The water outlet pipe 53 is provided in the housing 1. One end of the water outlet pipe 53 is connected to the receiving groove 11, and the other end of the water outlet pipe 53 is connected to the water outlet 8.

[0100] Working principle of the above technical solution: During actual use, when the detection device is detecting, the first electromagnet 44 and the second electromagnet 52 are started, so that the first baffle 41 and the second baffle 50 respectively enter the first occlusion groove 42 and the second occlusion groove 49, exposing the first through hole 38 and the second through hole 48, making the first through hole 38, the second through hole 48 and the water outlet pipe 53 communicate. During detection, cold water sequentially passes through the first through hole 38 and the second through hole 48 and enters the water outlet pipe 53, and then is discharged from the water outlet 8. When the cold water passes through the first through hole 38, the cold water drives the second rotating rod 39 to rotate through the blade 40. When the second rotating rod 39 rotates, the rotation speed will be detected by the speed measurement sensor 47. When the cold water flow rate remains unchanged, the speed detected by the speed measurement sensor 47 remains unchanged. When the cold water flow rate changes, the speed detected by the speed measurement sensor 47 changes; at the same time during the detection process, the cold water drives the floating block 36 to move upward through buoyancy, so that the floating block 36 drives the connecting block 37 to move upward, thereby enabling the connecting block 37 to squeeze the pressure sensor 35, so that the pressure sensor 35 detects a pressure value. When this pressure value is less than the preset value, it indicates that the amount of cold water in the detection pipe 4 has not reached the preset value.

[0101] Beneficial effects of the above technical solution: Through the design of the above structure, the monitoring device 33 is provided to monitor the flow rate of the cold water in the detection pipe 4 in real time, avoiding the influence of the real-time change of the cold water flow rate in the detection pipe 4 on the measurement result of the detection device 2; at the same time, the monitoring device 33 can detect the water level height in the detection pipe 4. When the water level height is insufficient, the controller starts the servo motor 19, so that the cleaning block 16 partially enters the water outlet 8, reducing the water output of the water outlet 8, increasing the water surface height in the cold water pipe 4, avoiding too little cold water in the detection pipe 4 from affecting the measurement result, and at the same time causing the heating pipe 3 to dry-burn the top detection pipe 3, affecting the service life of the detection pipe 4; and when the sealing device 10 seals the detection pipe 4, the dehumidifying motor 46 is started, so that the dehumidifying motor 46 drives the second rotating rod 39 to rotate, and the second rotating rod 39 drives several blades 40 to rotate, exhausting the humid air in the detection pipe 4, avoiding the inner wall of the detection pipe 4 from rusting.

[0102] In one embodiment, a friction pad is provided on the outer wall of the cleaning ring 24.

[0103] Working principle and beneficial effects of the above technical solution: The friction pad provided on the cleaning ring 24 can increase the cleaning effect of the cleaning ring 24.

[0104] In one embodiment, the positions of the first through hole 38, the second through hole 48 and the water outlet pipe 53 correspond to each other.

[0105] Working principle and beneficial effects of the above technical solution: The corresponding positions of the first through hole 38, the second through hole 48 and the water outlet pipe 53 facilitate the flow of water.

[0106] In one embodiment, the floating block 36 is made of foam.

[0107] Working principle and beneficial effects of the above technical solution: Foam has a small mass, good buoyancy in water, and is inexpensive.

[0108] In one embodiment, the sealing plate 17 is made of a rubber material.

[0109] Working principle and beneficial effects of the above technical solution: Making the sealing plate 17 from a rubber material can improve the sealing effect.
