Description

Technical Field

[0001] This utility model relates to the field of ultraviolet sterilizers, and in particular to a protective cover for an ultraviolet sterilizer. Background Technology

[0002] An ultraviolet (UV) sterilizer is a device that utilizes the sterilizing properties of ultraviolet light to kill microorganisms in various liquids, air, or object surfaces, thereby achieving disinfection and purification. Commonly used UV sterilizers are mainly divided into three types based on their structure and application scenarios: duct type, open channel type, and mobile type, each with its own unique characteristics and applicable scope.

[0003] Among them, open channel ultraviolet sterilizers are widely used in municipal sewage treatment, industrial wastewater treatment and drinking water purification because of their advantages such as large flow rate processing capacity, good water quality adaptability and easy maintenance.

[0004] However, in traditional open-channel UV sterilizers, the lamps are typically exposed, making them prone to accumulating impurities that obstruct UV light transmission and thus affect sterilization efficiency. To address this, existing open-channel UV sterilizers are generally equipped with cleaning devices, but these are usually manually operated, and given the large number of lamps in such systems, cleaning is time-consuming. Furthermore, exposed lamps are easily damaged during transport, affecting the device's continued usability.

[0005] Therefore, a protective cover for an ultraviolet sterilizer is proposed to solve the above problems. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 - Figure 3This utility model provides an embodiment of an ultraviolet sterilizer protective cover, including a bracket 1. The bracket 1 is welded from multiple metal rods. Supporting guide rods 2 are mounted on the upper surface of the bracket 1. Multiple sets of supporting guide rods 2 are fixed to the bracket 1 by bolts and are evenly distributed front and back. Two sets of hanging rings 21 are fixedly connected to the upper surface of the supporting guide rods 2, evenly distributed at the left and right ends of the upper surface of the supporting guide rods 2. An air pipe 22 and a power cord 23 are both mounted on the upper surface of the supporting guide rods 2. A lamp tube 3 is mounted on the left surface of the supporting guide rods 2. The power cord 23 and the lamp tube 3 are electrically connected. The guide rod 2, air pipe 22, power cord 23, and lamp tube 3 are all existing technologies and are internal components of open-channel ultraviolet sterilizers. They are generally used in sewage channels to achieve sterilization. Open-channel ultraviolet sterilizers are existing technology and can be implemented by those skilled in the art. Therefore, they will not be described in detail in this case. A cleaning mechanism is provided on the upper surface of the guide rod 2. This mechanism can promptly remove impurities adhering to the outer wall of the lamp tube 3, preventing accumulation and affecting the propagation of ultraviolet light, thus ensuring stable sterilization. The cleaning mechanism includes a drive component and a cleaning component. A protective component is provided on the front surface of the bracket 1. When the device is removed from the sewage channel, the protective component can block the exposed areas on both sides of the lamp tube 3, providing protection and preventing damage to the lamp tube 3. The left and right sides of the lamp tube 3 are connected to the guide rod 2 and will not be subject to collision.

[0035] Reference Figure 2 - Figure 4 The drive assembly includes a support plate 41, a drive motor 42 is provided on the left surface of the support plate 41, and a screw 43 is fixedly connected to the output shaft of the drive motor 42. Both the drive motor 42 and the screw 43 are existing technologies and can be implemented by those skilled in the art. Starting the drive motor 42 can drive the screw 43 to rotate in the forward and reverse directions. A guide plate 44 is threadedly connected to the outer wall of the screw 43. The rotating screw 43 can drive the guide plate 44 to move in the left and right directions. The cleaning assembly includes a cleaning plate 55. Multiple sets of longitudinally equidistant through grooves are opened on the right surface of the cleaning plate 55. The inner wall of the through grooves is made of rubber. A slot 501 is opened on the upper surface of the cleaning plate 55. An insert plate 52 is elastically connected to the inner wall of the guide plate 44 through a compression spring 51. The insert plate 52 and the slot 501 fit together. A connecting rod 54 is fixedly connected to the upper surface of the insert plate 52. A handle 53 is fixedly connected to the upper surface of the connecting rod 54. The handle 53 is convenient for gripping.

[0036] Reference Figure 2 - Figure 4The support plate 41 is fixedly connected to the upper surface of the bracket 1. The screw 43 passes through and is rotatably connected to the right surface of the support plate 41. The support plate 41 is provided in two sets, evenly distributed at the left and right ends of the upper surface of the bracket 1, which can provide support for the left and right ends of the screw 43. The cleaning plate 55 passes through and is slidably connected to the upper surface of the support guide rod 2. The lamp tube 3 is inserted into the inner wall of the cleaning plate 55. The rubber part of the outer wall of the lamp tube 3 and the inner wall of the through groove are in contact. When the cleaning plate 55 moves laterally, it can clean the outer wall of the lamp tube 3. One end of the compression spring 51 is fixedly connected to the upper surface of the insert plate 52. The other end of the compression spring 51 is fixedly connected to the inner wall of the top of the guide plate 44. The insert plate 52 passes through and is slidably connected to the lower surface of the guide plate 44. When the insert plate 52 moves upward, it will squeeze the compression spring 51 to generate a reaction force. The connecting rod 54 passes through and is slidably connected to the upper surface of the guide plate 44. The insert plate 52 is inserted into the inner wall of the slot 501. When the insert plate 52 moves upward, it will disengage from the slot 501.

[0037] Reference Figure 1 , Figure 5 , Figure 6 The protective component includes a protective plate 61. The left and right ends of the rear surface of the protective plate 61 are both protruding plates and are in contact with the inner sides of the left and right sides of the bracket 1. The lower surface of the protective plate 61 is in contact with the upper surface of the bracket 1. One end of the connecting spring 62 is fixedly connected to the inner wall on the right side of the protective plate 61, and the other end of the connecting spring 62 is fixedly connected to the locking block 63.

[0038] Reference Figure 1 , Figure 5 , Figure 6 The locking block 63 is slidably connected to the left surface of the protective plate 61. When the locking block 63 moves to the right, it will retract into the protective plate 61 and squeeze the connecting spring 62 to generate a reaction force. The locking block 63 is locked onto the rear surface of the bracket 1, which can limit the protective plate 61 and prevent it from being removed from the bracket 1. The left end of the rear surface of the locking block 63 is set as a slope. When the slope is squeezed, the locking block 63 will move to the right.

[0039] Working principle: Before using this device, first place the support guide rod 2 on the bracket 1, then slide the support guide rod 2 back and forth to the appropriate position, and fix the support guide rod 2 with bolts. During this process, pull the handle 53 upward to drive the insert plate 52 and the connecting rod 54 to move upward to avoid obstruction. When the support guide rod 2 is installed, move the cleaning plate 55 until all the slots 501 are aligned with the insert plate 52. Then release the handle 53. At this time, the compression spring 51 will push the insert plate 52 and the slots 501 to insert. This can not only enable the subsequent cleaning plates 55 to clean the multiple sets of lamp tubes 3 simultaneously, but also prevent the guide plate 44 from rotating when moving.

[0040] During operation, the drive motor 42 is activated to rotate the screw 43, which in turn drives the guide plate 44 to move left and right. As the guide plate 44 moves, the cleaning component connected to it moves synchronously. When the cleaning plate 55 in the cleaning component moves laterally, it cleans the outer wall of the lamp tube 3, removing adhering impurities and preventing impurities from accumulating and affecting ultraviolet light transmission, thus ensuring a stable sterilization effect.

[0041] If the cleaning plate 55 needs to be replaced, pull the handle 53 upwards. The handle 53 will move the connecting rod 54 upwards, and the connecting rod 54 will move the insert plate 52 upwards. The insert plate 52 will squeeze the compression spring 51 to generate a reaction force. At the same time, the insert plate 52 will disengage from the slot 501. At this time, the cleaning plate 55 can be removed for replacement.

[0042] When the device is removed from the sewage ditch, the protective plate 61 is inserted into the front of the bracket 1. During insertion, the inclined surface of the locking block 63 is pressed, causing the locking block 63 to retract into the protective plate 61 to release the obstruction and compress the connecting spring 62 to generate a reaction force. When fully inserted, the locking block 63 is pushed out by the connecting spring 62 and engages with the rear of the bracket 1, limiting the position of the protective plate 61. Similarly, another set of protective plates 61 is installed on the rear of the bracket 1. To remove them later, press the locking block 63 to retract it into the protective plate 61 to release the obstruction, and then remove the protective plate 61.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
