Description

Technical Field

[0001] This utility model relates to the field of illumination measurement technology, and in particular to an illuminance measuring device. Background Technology

[0002] Indoor lighting is a very important indicator that directly reflects the lighting quality of a space. Illuminance measurement in indoor lighting refers to measuring the illuminance of various indoor surfaces, such as walls, floors, ceilings, indoor facilities, and work surfaces. It is an essential part of energy-saving on-site testing.

[0003] In actual measurements, when there are few measuring points, the instrument can be fixed at the measuring point for automatic measurement; when there are many measuring points, such as the daylight measurement of a basketball court or canteen, it is generally necessary for the operator to hold a lux meter and measure and record the data at each point one by one, which is time-consuming and laborious. Utility Model Content

The words “comprising” or “including” and similar terms mean that the element or object preceding “comprising” or “including” covers the element or object listed following “comprising” or “including” and its equivalents, and does not exclude other elements or objects. The words “connected” or “linked” and similar terms are not limited to physical or mechanical connections and can include electrical connections, whether direct or indirect. The singular forms “a,” “the,” and “the” used in this application specification and appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0033] Please refer to the following for details. Figure 1-6An illuminance measuring device includes a housing 1 and an illuminance meter 2. The housing 1 has casters 3 at its bottom. Inside the housing 1 are a lifting mechanism 4 and a rotating mechanism 5. The lifting mechanism 4 is installed at the bottom of the housing 1, and the rotating mechanism 5 is mounted on the lifting mechanism 4. The illuminance meter 2 is mounted on the rotating mechanism 5. The casters 3, lifting mechanism 4, and rotating mechanism 5 are used to drive the illuminance meter 2 to move, lift, and rotate, respectively. This allows the illuminance meter 2 to move in position and adjust its height and angle, thus broadening its application range and eliminating the need for constant handheld operation. The lifting mechanism 4 and rotating mechanism 5 are concealed inside the housing 1, reducing damage to the internal mechanisms from external collisions or accidental contact. They also protect against dust, moisture, and other contaminants, extending the lifespan of the internal mechanisms.

[0034] Specifically, the lifting mechanism 4 includes a support plate 401 and a first drive device 402 for driving the lifting of the mounting plate.

[0035] In this embodiment, the first driving device 402 is an electric push rod, which drives the lifting and lowering of the mounting plate by extending and retracting the output shaft of the electric push rod; in some other feasible embodiments, the first driving device 402 may also be a scissor lift.

[0036] Specifically, the rotating mechanism 5 includes a second driving device 501, a rotating disk 502, a rotating shaft 503, and a dividing disk 504. The second driving device 501 is fixedly installed on the support plate 401, the rotating disk 502 is fixedly installed on the output shaft of the second driving device 501, the rotating shaft 503 is rotatably installed on the support plate 401, and the dividing disk 504 is fixedly installed on the rotating shaft 503 and works in conjunction with the rotating disk 502. The rotating disk 502 is provided with a round pin 505, and the dividing disk 504 is provided with a plurality of dividing slots 506 distributed radially along the dividing disk 504. The illuminance meter 2 is installed on the top of the rotating shaft 503. The rotating disk 502 rotates continuously at a constant angular velocity under the action of the second drive device 501. When the pin 505 on the rotating disk 502 enters the slot 506 of the dividing disk 504, the dividing disk 504 rotates under the drive of the pin 505. When the pin 505 leaves the slot 506 on the other side, the dividing disk 504 is locked by the rotating disk 502 and remains stationary until the pin 505 enters the other slot 506 of the dividing disk 504 again, and the above movement is repeated. Therefore, the dividing disk 504 performs intermittent movement, so that the illuminance meter 2 has time to stop and start to detect the illuminance.

[0037] In this embodiment, the second driving device 501 is a servo motor.

[0038] Furthermore, it also includes a clamping mechanism 6 for holding the illuminance meter 2. The clamping mechanism 6 includes a base 601 and a screw 602. The base 601 is fixedly mounted on the rotating shaft 503. The base 601 has a threaded hole adapted to the screw 602. The screw 602 is movably mounted on the base 601. The illuminance meter 2 is detachably mounted in the base 601 via the screw 602. The clamping mechanism 6 facilitates the installation and removal of the illuminance meter 2, enabling maintenance, charging, and other operations on the illuminance meter 2.

[0039] In this embodiment, the screw 602 is a wing screw 602. The wing head design allows the operator to tighten or loosen it directly by hand, eliminating the need for tools such as screwdrivers and wrenches.

[0040] Furthermore, one end of the screw 602 is provided with a contact element 603, which is located inside the base 601. The contact element 603 increases the contact area with the illuminance meter 2, ensuring that the illuminance meter 2 can be stably fixed in the base 601.

[0041] In this embodiment, the contact 603 is circular and made of rubber.

[0042] Furthermore, a protective plate 101 is provided on each of the two sides of the top of the housing 1. The protective plate 101 can move on the housing 1. The protective plate 101 is provided with a slider, and a sliding groove is opened on the top of the housing 1. The protective plate 101 can be movably connected to the top of the housing 1 through the slider and the sliding groove. The protective plate 101 is movably installed on the housing 1, which can effectively block dust and moisture from entering the housing 1. At the same time, the movable protective plate 101 can be pulled away from the housing 1 first when the lux meter 2 extends out of the housing 1, and then the protective plate 101 can be closed, so as not to interfere with the extension of the lux meter 2.

[0043] Furthermore, a semi-circular hole 102 is provided on the inner side of the protective plate 101, and the two protective plates 101 form a circular hole for the rotating shaft 503 to pass through and rotate.

[0044] Furthermore, a plurality of magnetic elements 103 are provided on the inner sidewall of the protective plate 101. The magnetic elements 103 on the two protective plates 101 are positioned opposite each other and attract each other, so that the two protective plates 101 can be fixed together by the magnetic elements 103.

[0045] In this embodiment, the magnetic attractors 103 on the two protective plates 101 are magnets that attract each other; in other feasible embodiments, the magnetic attractor 103 on one protective plate 101 is a magnet, and the magnetic attractor 103 on the other protective plate 101 is a metal that can be attracted by a magnet, such as iron or nickel.

[0046] It is worth mentioning that, in its normal state (when illuminance meter 2 is not in use), illuminance meter 2 is hidden inside housing 1, as shown below. Figure 1 As shown, this facilitates the transportation of the device.

[0047] It should be noted that all standard parts used in this application can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
