Description

Technical Field

[0001] The utility model relates to the field of refrigeration equipment detection devices, in particular to a refrigeration effect detection device for refrigeration equipment. Background Art

[0002] With the development of society and the improvement of people's living standards, people have higher and higher requirements for the comfort of the perceived temperature. Various refrigeration equipment have emerged as the times require. Existing refrigeration equipment mainly consists of a compressor, an expansion valve, an evaporator, a condenser and accessories, and pipelines. Although the refrigeration equipment is highly practical, it often fails, resulting in poor refrigeration effect, thus affecting people's quality of life in hot weather.

[0003] When the refrigeration equipment is damaged, it is usually necessary to use a detection device to detect its wind force and temperature. At present, the most commonly used detection method for refrigeration effect is to use a hand-held thermometer to detect the temperature at various positions in the room of the refrigeration equipment. The thermometer needs to be placed at the air outlet position of the refrigeration equipment for a period of time to ensure the stability of the detected temperature. However, placing the hand-held thermometer at the air outlet of the refrigeration equipment for a long time not only consumes labor, but also the temperature measurement data is easily affected by humans and has low accuracy. At the same time, it is difficult to detect the wind speed at various positions of the refrigeration equipment only by using a thermometer, resulting in poor refrigeration detection effect. Therefore, it is particularly important to design a new type of refrigeration effect detection device for refrigeration equipment to change the above technical defects and improve the practicability of the overall detection device. Summary of the Utility Model

[0004] The utility model provides a refrigeration effect detection device for refrigeration equipment to solve the problems that the refrigeration effect detection of existing refrigeration equipment needs to be carried out by manually holding a thermometer and it is difficult to detect the wind speed.

[0005] In order to achieve the above object, the technical solution adopted by the utility model is as follows:

[0006] A refrigeration effect detection device for refrigeration equipment includes a support rod (4) supported by a support mechanism. One end of the support rod (4) is fixedly connected with a support block (7). A temperature detection element is installed on the support block (7) to detect temperature. At least one side of the support block (7) is rotatably connected with a rotating plate (10). A plurality of through slots are provided in the rotating plate (10). A wind blade is rotatably installed in each through slot through a wind blade shaft to sense the wind force, and a rotation sensor is respectively configured on the wind blade shaft of each wind blade.

[0007] Further, a data acquisition system is arranged at the other end of the support rod (4), and the temperature detection element and the rotation sensor are respectively electrically connected with the data acquisition system.

[0008] Further, a connecting member (6) is slidably mounted on the support rod (4), and a connecting rod (13) is rotatably connected between the connecting member (6) and the rotating plate (10).

[0009] Further, one section of the support rod (4) is a lead screw, the connecting member (6) is slidably sleeved on the lead screw section of the support rod (4) through its own light hole, and a screw sleeve (16) is coaxially rotatably connected to one end of the connecting member (6), and the screw sleeve (16) is screwed and installed on the lead screw section of the support rod (4) through its own threaded through hole.

[0010] Further, the support rod (4) is supported by a support mechanism to be horizontal or vertical.

[0011] Compared with the prior art, the advantages of the present utility model are as follows:

[0012] In the present utility model, the support rod is supported by a support mechanism to be horizontal or vertical, and the refrigeration temperature of the refrigeration device is detected by the temperature detection element at one end of the support rod, and no manual long-term holding work is required during detection. When the wind speed needs to be detected, the rotating plate can be rotated so that the wind blade in the through groove is in contact with the air outlet of the refrigeration device, then the air outlet of the refrigeration device will drive the wind blade to rotate, and further the rotation sensor on the wind blade shaft corresponding to the wind blade generates a signal, and thus the air outlet wind force of the refrigeration device can be known.

[0013] Compared with the prior art, the present utility model overcomes the defect of manually holding a thermometer to detect the refrigeration temperature, and can synchronously detect the air outlet wind force of the refrigeration device as needed, and has good practicability.

[0017] The present utility model will be further described below with reference to the drawings and embodiments.

[0018] Such as Figure 1As shown in the figure, this embodiment discloses a detection device for the refrigeration effect of a refrigeration device, including a support rod 4 supported horizontally or vertically by a support mechanism. Specifically, the support mechanism includes a support base 1, a connecting rod 2 is vertically and fixedly connected to the support base 1, a connecting block 3 is fixed to the rod end of the support rod 2, the support rod 4 passes through the connecting block 3 and is integrally fixed with the connecting block 3, and the support rod 4 is perpendicular to the connecting rod 2. When the support base 1 is fixed on the ground, the support rod 4 is horizontally level, and when the support base 1 is fixed on the wall surface, the support rod 4 is vertical.

[0019] One end of the support rod 4 is fixedly connected with a support block 7, and a temperature detection element 19 is arranged on the support block 7. The temperature detection element 19 is used to sense temperature and generate corresponding electrical signals. The other end of the support rod 4 is provided with a data acquisition system 20. The data acquisition system 20 is integrated with a processor, a display, and a signal collector. The temperature detection element 19 is connected to the input end of the signal collector through a signal line penetrating through the inside of the support rod 4. The output end of the signal collector is connected to the signal input end of the data acquisition system 20, and the signal output end of the data acquisition system 20 is connected to the input end of the display. Thus, the temperature signal collected by the temperature detection element 19 is sent to the processor in the data acquisition system 20 for processing, and the processor sends the temperature data to the display for display.

[0020] At least one side surface of the support block 7 is provided with a rotating plate 10. In this embodiment, the example of the support block 7 having rotating plates 10 on two symmetric side surfaces is used for illustration. One end of each rotating plate 10 is respectively rotationally connected to the corresponding side surface of the support block 7 through a rotating shaft 9 in a rotating connection port 8. Thus, each rotating plate 10 can rotate and open and fold relative to the support rod 4. As Figure 1 、 Figure 3 shown, each rotating plate 10 is respectively provided with a plurality of through grooves 14. In this embodiment, the respective through grooves 14 are linearly distributed along the long side of the corresponding rotating plate 10. Each through groove 14 is respectively rotationally installed with a wind blade 11 through a wind blade shaft, and a rotation sensor is respectively installed on each wind blade shaft.

[0021] When it is necessary to detect the air outlet wind force of the refrigeration device, the rotating plate 10 is rotated and opened until the air outlet of the refrigeration device can pass through the through groove 14. Thus, the air outlet wind force of the refrigeration device causes the wind blade 11 in the through groove 14 to rotate, and then the rotation sensor generates a signal. The signal line of the rotation sensor is connected to the input end of the signal collector in the data acquisition system 20. Thus, the rotation signal detected by the rotation sensor is sent to the processor in the data acquisition system 20 for processing. The processor obtains the rotation speed of the corresponding wind blade based on the rotation signal collected by the rotation sensor, and then obtains the air outlet wind force of the refrigeration device. The air outlet wind force data obtained by the processor is sent to the display for display.

[0022] In this embodiment, a section of the support rod 4 adjacent to the support block 7 is set as a lead screw section 5, and a connecting member 6 is assembled on the lead screw section 5. Specifically, the connecting member 6 has a central light hole 15 passing through itself. The connecting member 6 is slidably sleeved on the lead screw section 5 of the support rod 4 through its light hole 15, so that the connecting member 6 can slide along the central axis direction of the lead screw section 5 of the support rod 4. A connecting rod 13 is provided between each rotating plate 10 and the connecting member 6. One end of each connecting rod 13 is rotatably connected to the rotating plate 10, and the other end is rotatably connected to a rotating clamping port 12 on the side surface of the connecting member 6. Thus, when the connecting member 6 slides on the lead screw section 5 of the support rod 4, it can drive each rotating plate 10 to open or fold relative to the support rod 4.

[0023] It should be noted that when there are multiple rotating plates 10, the rotating plates 10 are circumferentially and equally spaced around the support rod 4. One end of each rotating plate 10 is rotatably connected to the corresponding side surface of the support block 7 through a rotating shaft, and a connecting rod 13 is rotatably connected between each rotating plate 7 and the connecting member 6, thus forming a rib structure of an umbrella. When each rotating plate 10 is opened by moving the connecting member 6, it is equivalent to forming an umbrella surface, and the air outlet of the refrigeration device is received through the umbrella surface, so that the air outlet wind force of the refrigeration device can be measured better.

[0024] In this embodiment, as Figure 2 shown, a screw sleeve 16 is arranged on the axial end face of one end of the connecting member 6. A ring groove 17 is provided on the axial end face of this end of the connecting member 6. One end of the screw sleeve 16 is fixed with a ring seat 18, and the ring seat 18 of the screw sleeve 16 is rotatably connected in the ring groove 17 of the connecting member 6, so that the screw sleeve 16 is rotatably connected to the axial end face of one end of the connecting member 6. The screw sleeve 16 is screwed and installed on the lead screw section 5 of the support rod 4 through its threaded through hole. Thus, when the screw sleeve 16 is rotated, the connecting member 6 can slide along the lead screw section 5 of the support rod 4, and a good sliding support effect is achieved through the lead screw section 5 of the support rod 4, and the sliding positioning of the connecting member 6 can be realized through the threaded cooperation between the screw sleeve 16 and the lead screw.
