Description

Technical Field

[0001] This utility model relates to the field of sensor technology, and more specifically, to an adjustable photosensitive sensor. Background Technology

[0002] A photosensitive sensor, one type of sensor, has the function of responding to or converting external light signals or light radiation. It is often used to be installed with outdoor lighting fixtures, enabling the lighting fixtures to automatically adjust whether to illuminate based on the outdoor light, which can effectively reduce power waste and improve energy efficiency.

[0003] Publication No. CN210662769U discloses a photosensitive sensor, the technical solution of which includes a photosensitive device. The photosensitive device is covered with a filter cover, which filters out light with a wavelength of 380-800nm. Alternatively, the surface of the light-transmitting device of the photosensitive sensor is coated with a filter layer to filter out light with a wavelength of 380-800nm. The filter layer is composed of a mixture A of silicon oxide and lithium oxide and a mixture B of silicon oxide and titanium oxide. The mixture A and the mixture B are alternately coated 40-60 times to form the filter layer.

[0004] The aforementioned patent utilizes sensors to receive different wavelengths of natural light and generate differential signals, enabling accurate identification of whether sunlight is present in the environment. This achieves all-weather intelligent energy-saving lighting and improves environmental protection. However, when cleaning the filter cover, the aforementioned technical solution typically requires staff to manually wipe the dust off the filter cover surface with a cloth. To reduce dust residue after wiping, the cloth needs to be washed multiple times, making the process overly cumbersome. Furthermore, if the dust on the filter cover is not cleaned for an extended period, it will affect the photosensitive sensor's judgment of external light, resulting in wasted power and impacting energy-saving performance. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an adjustable photosensitive sensor that solves the problem that cleaning the filter requires manual wiping by staff, which is too cumbersome. Furthermore, if the filter is not cleaned for a long time, it will affect the photosensitive sensor's judgment of external light, thus wasting power and affecting energy-saving performance.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an adjustable photosensitive sensor includes a sensor body, a mounting ring rotatably connected to the sensor body, the mounting ring and the sensor body being connected by a snap-fit ​​assembly, a cleaning plate fixedly connected inside the mounting ring, a rotating plate rotatably connected inside the mounting ring, a plurality of intersecting through slots being provided on both the cleaning plate and the rotating plate, a plurality of limiting blocks fixedly connected to the cleaning plate, the plurality of limiting blocks being slidably connected to the through slots on the rotating plate, and a control assembly for controlling the rotation of the rotating plate being provided on the sensor body.

[0007] By adopting the above technical solution, when it is necessary to clean the dust on the photosensitive sensor, the control component drives the rotating plate to rotate, and simultaneously drives the through slots on the rotating plate and the cleaning plate to be staggered. At this time, the through slots on the rotating plate and the cleaning plate are in a closed state, which can prevent external dust from entering the mounting ring during cleaning, thus improving the cleaning effect. As the rotating plate rotates, the limiting block is affected and moves at the through slot on the rotating plate. When the limiting block moves to contact one side of the through slot on the rotating plate, the locking component releases the restriction on the mounting ring. At this time, the cleaning plate on the mounting ring is no longer restricted, and the limiting block can drive the... The cleaning plate rotates and cleans the dust on the sensor body, thus automatically cleaning the dust on the sensor body, improving the photosensitive sensor's judgment of external light, reducing power waste, and improving energy efficiency. After cleaning, the control component can drive the rotating plate back to its original position. At this time, the through slots on the rotating plate and the cleaning plate are aligned with each other, allowing external light to shine on the sensor body and avoiding affecting the normal judgment of the sensor. Furthermore, the snap-fit ​​component can also separate the mounting ring from the sensor body and clean the cleaning plate, improving the subsequent cleaning effect of the sensor body.

[0008] The present invention is further configured such that: the snap-fit ​​assembly includes several grooves formed on the inner sidewall of the mounting ring, a snap-fit ​​block is slidably connected in the groove, the snap-fit ​​block and the groove are connected by a spring, and several slots are formed on the sidewall of the sensor body, and when the spring is in its natural state, the snap-fit ​​block protrudes from the groove opening.

[0009] By employing the aforementioned snap-fit ​​assembly, when the through slots on the limiting block and the rotating plate come into contact with each other, the control assembly can drive the rotating plate to apply force to the limiting block, and simultaneously transmit the force to the mounting ring. At this time, the snap-fit ​​block on the mounting ring is affected by the force and begins to move into the groove, causing the spring to deform and compress. At this point, the snap-fit ​​block and the slot separate from each other, driving the mounting ring to rotate. After the mounting ring stops rotating, the spring begins to deform and return to its original position, causing the snap-fit ​​block to protrude out of the groove and re-enter the slot to snap into each other. This achieves the effect of snapping the mounting ring and the sensor body together, facilitating the maintenance of the sensor body.

[0010] The present invention is further configured such that: the control component includes an adjusting block fixedly connected to the rotating plate; a rotating ring is rotatably connected to the side wall of the mounting ring; a connecting rod is fixedly connected to the rotating ring; the connecting rod and the adjusting block are fixedly connected; and a driving component for driving the rotating ring to rotate is provided on the mounting ring.

[0011] By using the aforementioned snap-fit ​​assembly, when it is necessary to drive the rotating plate to rotate, the driving component drives the rotating ring to rotate. At the same time, the rotating ring drives the adjusting block to start rotating through the connecting rod, and the adjusting block drives the rotating plate to rotate, thereby achieving the effect of driving the rotating plate to rotate, which facilitates the cleaning of dust on the sensor body.

[0012] The present invention is further configured such that: the driving component includes a fixed frame fixedly connected to the side wall of the sensor body, a motor fixedly connected to the top surface of the fixed frame, a rotating wheel fixedly connected to the output end of the motor, and the rotating wheel and the rotating ring are connected by a belt.

[0013] By using the aforementioned driving component, when the rotating ring is driven to rotate, the motor is started, and the output end of the motor drives the rotating wheel to rotate. At the same time, the rotating wheel drives the belt to move, and the belt drives the rotating ring to rotate, thereby achieving the effect of driving the rotating ring to rotate.

[0014] The present invention is further configured such that: the sidewalls of the rotating wheel and the rotating ring are provided with a plurality of tooth grooves arranged in a ring array, and the inner sidewall of the belt is fixedly connected with teeth that mesh with the tooth grooves.

[0015] By adopting the above technical solution, the transmission efficiency between the belt and the pulley and rotating ring can be increased, thereby improving the transmission effect.

[0016] The present invention is further configured such that limiting plates are fixedly connected to several of the limiting blocks.

[0017] By adopting the above technical solution, the cleaning plate and the rotating plate can be prevented from separating when the mounting ring is removed, thereby improving the stability between the cleaning plate and the rotating plate.

[0018] The present invention is further configured such that: a connecting ring is fixedly connected to the inner sidewall of the mounting ring, and a sponge layer is placed between the connecting ring and the cleaning plate, and the sponge layer and the connecting ring are in contact with each other.

[0019] By adopting the above technical solution, when cleaning the cleaning board, applying tension to the sponge layer can remove the sponge layer from between the connecting ring and the cleaning board. Then, the sponge layer is cleaned. After cleaning, pressure is applied to the sponge layer to press it between the connecting ring and the cleaning board, and the sponge layer is fixed by the connecting ring, thereby achieving the effect of facilitating the cleaning of the cleaning board.

[0020] In summary, this utility model has the following beneficial effects: When it is necessary to clean the dust on the photosensitive sensor, the control component drives the rotating plate to rotate, and at the same time drives the through slots on the rotating plate and the cleaning plate to be staggered. At this time, the limiting block is affected and moves at the through slot on the rotating plate. When the limiting block moves to contact one wall of the through slot on the rotating plate, the locking component removes the restriction on the mounting ring. At this time, the limiting block can drive the cleaning plate to rotate and clean the dust on the sensor body, thereby achieving the effect of automatically cleaning the dust on the sensor body, improving the photosensitive sensor's judgment of external light, reducing power waste, and improving energy saving.

[0030] An adjustable photosensor, such as Figures 1-5 As shown, the sensor includes a sensor body 1, a mounting ring 2 rotatably connected to the sensor body 1, and the mounting ring 2 and the sensor body 1 connected by a snap-fit ​​assembly. A cleaning plate 3 is fixedly connected inside the mounting ring 2, and a rotating plate 4 is rotatably connected inside the mounting ring 2. Both the cleaning plate 3 and the rotating plate 4 have several intersecting through slots 5. Several limiting blocks 6 are fixedly connected to the cleaning plate 3, and the limiting blocks 6 are slidably connected to the through slots 5 on the rotating plate 4. The sensor body 1 is provided with a control assembly for controlling the rotation of the rotating plate 4. When it is necessary to clean the dust on the photosensitive sensor, the control assembly drives the rotating plate 4 to start rotating, and at the same time drives the through slots 5 on the rotating plate 4 and the cleaning plate 3 to be intersected. At this time, the through slots 5 on the rotating plate 4 and the cleaning plate 3 are in a closed state, which can prevent external dust from entering the mounting ring 2 during cleaning and improve the cleaning effect.

[0031] After the through slots 5 on the rotating plate 4 and the cleaning plate 3 are closed, the rotating plate 4 is driven to continue rotating. At the same time, the limiting block 6 is affected and moves at the through slot 5 on the rotating plate 4. When the limiting block 6 moves to contact one side of the through slot 5 on the rotating plate 4, the restriction on the mounting ring 2 is released by the snap-fit ​​component. At this time, the cleaning plate 3 on the mounting ring 2 is unrestricted. The limiting block 6 can drive the cleaning plate 3 to rotate and clean the dust on the sensor body 1, thereby achieving the effect of automatically cleaning the dust on the sensor body 1, improving the photosensitive sensor's judgment of external light, reducing power waste, and improving energy saving. After cleaning, the control component can drive the rotating plate 4 to return to its original position. At this time, the through slots 5 on the rotating plate 4 and the cleaning plate 3 are aligned with each other, allowing external light to shine on the sensor body 1, avoiding affecting the normal judgment of the sensor. Furthermore, the snap-fit ​​component can also separate the mounting ring 2 and the sensor body 1 and clean the cleaning plate 3, improving the subsequent cleaning effect of the sensor body 1.

[0032] like Figures 2-5 As shown, the snap-fit ​​assembly includes several grooves 7 formed on the inner sidewall of the mounting ring 2. A snap-fit ​​block 8 is slidably connected in the groove 7. The snap-fit ​​block 8 and the groove 7 are connected by a spring 9. Several slots 10 are formed on the sidewall of the sensor body 1. When the spring 9 is in its natural state, the snap-fit ​​block 8 protrudes from the groove 7. When the limiting block 6 and the through slot 5 on the rotating plate 4 are in contact with each other, the control assembly can drive the rotating plate 4 to apply a force to the limiting block 6, and at the same time transmit the force to the mounting ring 2. At this time, the snap-fit ​​block 8 on the mounting ring 2 is affected by the force and begins to move into the groove 7, and drives the spring 9 to deform and compress. At this time, the snap-fit ​​block 8 and the slot 10 separate from each other, and can drive the mounting ring 2 to rotate. After the mounting ring 2 stops rotating, the spring 9 begins to deform and return to its original state, and drives the snap-fit ​​block 8 to re-enter the slot 10 and snap-fit ​​with each other, thereby achieving the effect of snap-fitting the mounting ring 2 and the sensor body 1.

[0033] like Figures 1-5As shown, the control assembly includes an adjusting block 11 fixedly connected to the rotating plate 4, a rotating ring 12 rotatably connected to the side wall of the mounting ring 2, a connecting rod 13 fixedly connected to the rotating ring 12, the connecting rod 13 and the adjusting block 11 being fixedly connected, and a driving component for driving the rotating ring 12 to rotate on the mounting ring 2. The driving component includes a fixing frame 14 fixedly connected to the side wall of the sensor body 1, a motor 15 fixedly connected to the top surface inside the fixing frame 14, and a rotating wheel 16 fixedly connected to the output end of the motor 15. The rotating wheel 16 and the rotating ring 12 are connected by a belt 17. When it is necessary to drive the rotating plate 4 to rotate, the motor 15 is started remotely. The output of the drive motor 15 drives the wheel 16 to rotate, and the wheel 16 drives the belt 17 to move. The belt 17 drives the rotating ring 12 to rotate, and the rotating ring 12 drives the adjusting block 11 to rotate through the connecting rod 13. The adjusting block 11 drives the rotating plate 4 to rotate, thereby achieving the effect of driving the rotating plate 4 to rotate. The side walls of the wheel 16 and the rotating ring 12 are provided with a number of tooth grooves 18 arranged in a ring. The inner side wall of the belt 17 is fixedly connected with teeth 19 that mesh with the tooth grooves 18, which can increase the transmission efficiency between the belt 17 and the wheel 16 and the rotating ring 12 and improve the transmission effect.

[0034] like Figure 5 As shown, several limiting blocks 6 are fixedly connected with limiting plates 20, which can prevent the cleaning plate 3 and the rotating plate 4 from separating when the mounting ring 2 is removed, thereby improving the stability between the cleaning plate 3 and the rotating plate 4.

[0035] like Figure 5 As shown, a connecting ring 21 is fixedly connected to the inner wall of the mounting ring 2. A sponge layer 22 is placed between the connecting ring 21 and the cleaning plate 3. The sponge layer 22 and the connecting ring 21 are in contact with each other. When cleaning the cleaning plate 3, a pulling force is applied to the sponge layer 22, which can remove the sponge layer 22 from between the connecting ring 21 and the cleaning plate 3. Then the sponge layer 22 is cleaned. After cleaning, pressure is applied to the sponge layer 22 to press the sponge layer 22 into the space between the connecting ring 21 and the cleaning plate 3, and the sponge layer 22 is fixed by the connecting ring 21. This achieves the effect of facilitating the cleaning of the cleaning plate 3.

[0036] The working principle of this utility model is as follows: When it is necessary to clean the dust on the photosensitive sensor, the motor 15 is started, which drives the output end of the motor 15 to drive the rotating wheel 16 to rotate. At the same time, the rotating wheel 16 drives the belt 17 to move, which drives the rotating ring 12 to rotate. Meanwhile, the rotating ring 12 drives the adjusting block 11 to start rotating through the connecting rod 13. The adjusting block 11 drives the rotating plate 4 to rotate, and at the same time, the through grooves 5 on the rotating plate 4 and the cleaning plate 3 are staggered. At this time, the through grooves 5 on the rotating plate 4 and the cleaning plate 3 are in a closed state.

[0037] After the through slots 5 on the rotating plate 4 and the cleaning plate 3 are closed, the rotating plate 4 is driven to continue rotating. At the same time, the limiting block 6 is affected and moves at the through slot 5 on the rotating plate 4. When the limiting block 6 moves to contact one wall of the through slot 5 on the rotating plate 4, the adjusting block 11 can drive the rotating plate 4 to apply force to the limiting block 6, and at the same time transmit the force to the mounting ring 2. At this time, the locking block 8 on the mounting ring 2 is affected by the force and begins to move into the groove 7, and drives the spring 9 to deform and compress. At this time, the locking block 8 and the groove 10 separate from each other, and can drive the mounting ring 2 to rotate. At this time, the cleaning plate 3 on the mounting ring 2 is unrestricted. The limiting block 6 can drive the cleaning plate 3 to rotate and clean the dust on the sensor body 1, thereby achieving the effect of automatically cleaning the dust on the sensor body 1, improving the photosensitive sensor's judgment of external light, reducing power waste, and improving energy saving.

[0038] After cleaning, the drive motor 15 reverses, causing the rotating plate 4 to rotate and return to its original position. At this time, the through slots 5 on the rotating plate 4 and the cleaning plate 3 are aligned with each other, allowing external light to shine on the sensor body 1, thus avoiding affecting the normal judgment of the sensor. Furthermore, the setting of the locking block 8 and the locking slot 10 can also separate the mounting ring 2 and the sensor body 1, and clean the cleaning plate 3, improving the subsequent cleaning effect of the sensor body 1.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
