Description

Technical Field

[0001] This utility model belongs to the field of fire protection maintenance technology, specifically a cleaning device for smoke detectors used in fire protection maintenance. Background Technology

[0002] Fire protection systems are essential for the normal production, work, and safety of every unit. Fire protection facilities must be regularly maintained and serviced, and any malfunctions must be promptly addressed to ensure their proper functioning and effective early warning capabilities, protecting state property and public safety. Smoke and heat detectors are multi-element composite detectors composed of smoke sensors and semiconductor temperature sensors, and are crucial components for fire detection. Cleaning is necessary during fire protection maintenance.

[0003] A search revealed that patent CN222112878U discloses a cleaning device for smoke detectors used in fire protection maintenance. The device includes a fixed rod and a fixed cap. A fixed ring is welded to the top of the fixed rod, and a lifting assembly is located at the bottom. A stainless steel suction head is fixedly inserted through the inside of the fixed ring. One end of the stainless steel suction head is connected to a stainless steel conduit, and a fixed cap is fixedly fitted onto the outer surface of one end of the stainless steel conduit. The fixed cap is fixedly connected to the fixed rod via a support assembly. This design utilizes the suction force generated by the suction pump to draw dust adhering to the smoke-sensing area of ​​the smoke detector through the stainless steel suction head and conduit into the dust collection bag. The suction force is then filtered by the dust collection bag and filter screen, while the dust remains inside the dust collection bag and the collection box, thus effectively cleaning the dust adhering to the smoke-sensing area of ​​the smoke detector.

[0004] Analysis of the above technical solutions reveals that the overall length of the lifting assembly is limited, and during use, personnel often lift it entirely, making it difficult to support it on the ground. This leads to arm fatigue from prolonged lifting, thus reducing the cleaning effectiveness of the smoke detectors. Therefore, we provide a smoke detector cleaning device for fire protection maintenance to solve these problems. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a cleaning device for smoke detectors used in fire protection maintenance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a smoke detector cleaning device for fire protection maintenance, comprising a fixed cylinder, a column fixedly connected to the inner bottom wall of the fixed cylinder, and equidistantly arranged limiting blocks fixedly connected to the surface of the column, a sleeve slidably disposed inside the fixed cylinder, with the column sleeved on the outside of the limiting blocks, a limiting mechanism rotatably disposed at the bottom end of the sleeve, and the limiting mechanism sleeved on the outside of the column, two opposing guide grooves opened on the surface of the fixed cylinder, and the limiting mechanism slidably disposed between the two guide grooves, and a cleaning mechanism for cleaning the smoke detector disposed at the top end of the sleeve.

[0007] Preferably, the limiting mechanism includes an adjusting frame, which is sleeved on the outside of the limiting block and slidably disposed between two guide grooves. The bottom end of the sleeve is rotatably connected to the adjusting frame. Two opposing mounting grooves are provided inside the adjusting frame. Each of the two mounting grooves has a retaining plate elastically slidably disposed therein, and each retaining plate is engaged with the corresponding limiting block. Each retaining plate has a pull rod fixedly connected to its side, and the pull rod slides through to the outside of the adjusting frame.

[0008] Preferably, springs are fitted onto the surfaces of both pull rods, and the two ends of the springs are respectively fixed to the surface of the card plate and the inner wall of the mounting groove.

[0009] Preferably, the cleaning mechanism includes a handheld vacuum cleaner, which is mounted on the top of the sleeve via a bracket. The vacuum cleaner's suction end is connected to a fixed tube, one end of which is connected to a suction tube, and the bottom of the suction tube is fixed to the top of the sleeve via the bracket.

[0010] Preferably, the cleaning mechanism further includes a fixing frame, which is fixedly connected to the top of the sleeve and located on the opposite side of the suction pipe, and a cleaning sponge is detachably connected to the suction pipe.

[0011] Preferably, a base is fixedly connected to the bottom end of the fixed cylinder.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention, through the arrangement of a fixed cylinder, column, limiting block, sleeve, limiting mechanism, guide groove, and cleaning mechanism, allows the fixed cylinder to be placed below the smoke detector. Then, the user sprays cleaning agent or alcohol onto the cleaning sponge, and starts the handheld vacuum cleaner. The user then pulls the sleeve upwards to adjust the height, bringing the cleaning sponge and vacuum hose into contact with the smoke detector. The sleeve is positioned by the locking plate and limiting block, effectively preventing it from falling downwards. The user then rotates the sleeve to clean the surface of the smoke detector with the cleaning sponge, while the handheld vacuum cleaner removes dust and impurities from the filter surface of the smoke detector. During this process, the user does not need to continuously lift the sleeve, reducing arm fatigue. After use, simply pulling the two levers releases the locking plates and limiting blocks, allowing the sleeve to move downwards with the adjustment frame and be stored back into the fixed cylinder. This makes the device easy to carry and convenient to use. Attached Figure Description

[0021] 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.

[0022] like Figure 1-6 As shown, this embodiment proposes a cleaning device for a smoke detector used in fire protection maintenance, including a fixed cylinder 1. The top of the fixed cylinder 1 is open. A column 13 is fixedly connected to the inner bottom wall of the fixed cylinder 1. Limiting blocks 14 arranged at equal intervals are fixedly connected to the surface of the column 13. The bottom of the limiting blocks 14 is inclined, and the overall shape of the limiting blocks 14 is an inverted frustum, making the upper surface of the limiting blocks 14 horizontal. A sleeve 3 is slidably disposed inside the fixed cylinder 1, and the column 13 is sleeved on the outside of the limiting blocks 14. The sleeve 3 can slide up and down inside the fixed cylinder 1, and since the limiting blocks 14 are located inside the sleeve 3, they do not affect the normal up and down sliding of the sleeve 3. A limiting mechanism is rotatably disposed at the bottom end of the sleeve 3, and the limiting mechanism is sleeved on the outside of the column 13. Two opposing guide grooves 9 are opened on the surface of the fixed cylinder 1, and the limiting mechanism is slidably disposed on the two guide grooves 9. Between the guide grooves 9, the sleeve 3 can be adjusted vertically by the above-mentioned structure. At the same time, the limiting mechanism can prevent the sleeve 3 from falling downwards randomly inside the fixed cylinder 1, so that the limiting mechanism can be locked onto the corresponding limiting block 14. In addition, the sleeve 3 can rotate on the limiting mechanism, which is conducive to the subsequent rotation and cleaning of the smoke detector. Personnel can hold the fixed cylinder 1 with one hand and the sleeve 3 with the other hand to rotate it. The top of the sleeve 3 is provided with a cleaning mechanism for cleaning the smoke detector. After the sleeve 3 has completed the height adjustment, the cleaning mechanism is placed outside the smoke detector, and finally it can be cleaned. The mechanics, parts and equipment in this device all adopt conventional models in the existing technology. In addition, the circuit connection adopts conventional connection methods in the existing technology, which will not be described in detail here.

[0023] like Figures 1 to 6As shown, the limiting mechanism includes an adjusting frame 10, which is sleeved on the outside of the limiting block 14 and slidably disposed between two guide grooves 9. The bottom end of the sleeve 3 is rotatably connected to the adjusting frame 10. Two opposing mounting grooves 16 are provided inside the adjusting frame 10, and a retaining plate 12 is elastically slidably disposed in each of the two mounting grooves 16. Both retaining plates 12 are engaged with the corresponding limiting blocks 14. A pull rod 11 is fixedly connected to the side of each retaining plate 12, and the pull rod 11 slides through to the outside of the adjusting frame 10. The upper surface of the retaining plate 12 is inclined. With the above structure, when the sleeve 3 is pulled upward, the inclined surface of the retaining plate 12 will press against the bottom inclined surface of the limiting block 14. This causes the clamping plate 12 to slide into the mounting groove 16, allowing the sleeve 3 to be pulled upwards for adjustment. Since the bottom surface of the clamping plate 12 and the upper surface of the limiting block 14 are both horizontal, the adjusting frame 10 will not adjust downwards, making it convenient for personnel to adjust the height of the sleeve 3. After the sleeve 3 is used up, simply pull the two levers 11 to release the positioning of the two clamping plates 12 and the limiting block 14, allowing the sleeve 3 to move downwards normally with the adjusting frame 10, thereby storing the sleeve 3 in the fixed cylinder 1. This makes it easier for personnel to carry and place the device, making it more flexible and convenient to use. Furthermore, the sleeve 3 and the adjusting frame 10 can be directly pulled out from the fixed cylinder 1 for easy replacement of the components.

[0024] like Figure 6 As shown, springs 15 are fitted on the surfaces of both pull rods 11, and the two ends of the springs 15 are respectively fixed to the surface of the clamping plate 12 and the inner wall of the mounting groove 16. With the setting of the springs 15, the clamping plate 12 has the feature of automatic reset, which ensures the stable engagement between the clamping plate 12 and the limiting block 14. When the pull rod 11 is pulled, the clamping plate 12 will squeeze the spring 15. When the person releases the pull rod 11, the clamping plate 12 will automatically engage with the corresponding limiting block 14 under the elastic force of the spring 15.

[0025] like Figures 1 to 3 As shown, the cleaning mechanism includes a handheld vacuum cleaner 4, which is mounted on the top of the sleeve 3 via a bracket. The suction end of the handheld vacuum cleaner 4 is connected to a fixed tube 5, and one end of the fixed tube 5 is connected to a suction pipe 6. The bottom of the suction pipe 6 is fixed to the top of the sleeve 3 via the bracket. With the above structure, when the top of the sleeve 3 is below the smoke detector, the suction pipe 6 will be outside the filter of the smoke detector. Before this, the operator will turn on the handheld vacuum cleaner 4 in advance so that when the suction pipe 6 reaches the smoke detector, it can automatically perform dust extraction, ensuring the cleaning effect of the smoke detector. During this period, the operator can rotate the sleeve 3 so that the suction pipe 6 can thoroughly clean the smoke detector. The handheld vacuum cleaner 4 is an existing mature component and will not be described in detail here.

[0026] like Figures 1 to 3 As shown, the cleaning mechanism also includes a fixing frame 8, which is fixed to the top of the sleeve 3 and located on the opposite side of the suction pipe 6. A cleaning sponge 7 is detachably connected to the suction pipe 6. With the above structure, when the cleaning sponge 7 is on the outside of the smoke detector and in close contact with it, the surface of the smoke detector can be wiped clean by rotating the sleeve 3. Before use, the cleaning sponge 7 can be sprayed with cleaning agent to ensure the cleaning effect on the smoke detector. In addition, to facilitate cleaning the cleaning sponge 7, the cleaning sponge 7 and the fixing frame 8 are attached by Velcro.

[0027] like Figure 1 , Figure 3 and Figure 4 As shown, the bottom end of the fixed cylinder 1 is fixedly connected to the base 2. The base 2 provides stable support for the fixed cylinder 1, enhances the overall stability of the fixed cylinder 1, prevents the fixed cylinder 1 from tipping over at will, eliminates the need for personnel to continuously lift the fixed cylinder 1 for use, and reduces the cleaning work of personnel for the smoke detector.

[0028] The working principle and usage process of this utility model are as follows: First, place the fixed cylinder 1 below the smoke detector. Then, spray cleaning agent or alcohol onto the cleaning sponge 7. Next, start the handheld vacuum cleaner 4. Then, the user directly pulls the sleeve 3 upward to adjust the height, so that the cleaning sponge 7 and the suction tube 6 come into contact with the smoke detector. At this time, the sleeve 3 will be positioned by the clamping plate 12 and the limiting block 14, effectively preventing the sleeve 3 from falling downward at will. Then, the user rotates the sleeve 3, so that the cleaning sponge 7 can clean the surface of the smoke detector. Using the operation of the handheld vacuum cleaner 4... The suction pipe 6 extracts dust and impurities from the filter surface of the smoke detector. During use, the operator only needs to hold the fixed cylinder 1 with one hand and rotate the sleeve 3 with the other. After the sleeve 3 is used up, simply pull the two levers 11 to release the positioning of the two locking plates 12 and the limiting block 14, allowing the sleeve 3 to move downward with the adjusting frame 10, thereby storing the sleeve 3 inside the fixed cylinder 1. This makes it easier for the operator to carry and place the device, making it more flexible and convenient to use. Furthermore, the sleeve 3 and the adjusting frame 10 can be directly pulled out from the fixed cylinder 1 for easy replacement of the components.

For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Content not described in detail in this specification belongs to the prior art known to those skilled in the art.
