Description

Technical Field

[0001] The utility model relates to the technical field of temperature sensing detectors, in particular to a waterproof temperature sensing detector. Background Art

[0002] The temperature detector, also known as the temperature sensor, is generally composed of a base, a connecting seat, a temperature sensing frame and internal thermistor components. The connection between the connecting seat and the base can prevent water droplets from contaminating the components. Thermistors are used to detect high-temperature fires. In the initial stage of a fire, on the one hand, a large amount of smoke is generated, and on the other hand, a large amount of heat is released during the combustion process. The surrounding temperature rises sharply, causing the thermistor in the connecting seat to undergo physical changes, responding to abnormal temperature, temperature rate, temperature difference, etc., thereby converting the temperature signal into an electrical signal and performing alarm processing.

[0003] The above-mentioned and existing related technologies often have the following defects: after the base is fixed to the wall panel, the connecting seat and the base are generally fixed by multiple bolts. However, during the regular maintenance of the detector, personnel need to climb to a higher place to disassemble the connecting seat on the top, thereby causing leakage between the connecting seat and the base, so as to inspect the internal thermistor. However, tools are needed to operate the bolts during the disassembly and assembly process, which not only increases the amount of tools that personnel carry, but also greatly increases the disassembly and assembly time and reduces the maintenance efficiency of the detector.

[0004] To this end, we propose a waterproof temperature detector. Utility Model Content

[0016] Preferably, the cross section of the scraper is a right triangle, and the extension rod is located on the other side of the scraper slope.

[0017] The effects achieved by the above components are: the inclined surface of the scraper scrapes away the deposited dust, and the scraper with a right-angled triangle cross-section plays a role in better pushing the dust and connecting the extension rod.

[0018] Preferably, a circular plate is fixedly connected to the arc surface of the fixed rod, and the lower surface of the circular plate is slidably connected to the rotating rod.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1The utility model provides a technical solution: a waterproof temperature sensing detector, including a base 1, a connecting seat 2 is slidably connected to the lower surface of the base 1, a temperature sensing frame 3 is fixedly connected to the lower surface of the connecting seat 2, and a fixed rod 4 is fixedly connected to the inner wall of the temperature sensing frame 3. A limiting structure 5 is provided on the arc surface of the base 1, which achieves the effect of facilitating the disassembly and assembly between the connecting seat 2 and the base 1 of the waterproof temperature sensing detector, thereby avoiding the problem that personnel need to use tools to remove multiple bolts during the maintenance of the connecting seat 2, which increases the amount of tools carried by personnel and reduces the overall maintenance efficiency.

[0030] The specific settings and functions of the limiting structure 5 and the cleaning structure 6 are described in detail below.

[0031] like Figure 2 and Figure 3 As shown, the limiting structure 5 includes a plurality of connecting blocks 51, and the sides of the plurality of connecting blocks 51 close to each other are fixedly connected to the base 1, and the sides of the plurality of connecting blocks 51 away from each other are fixedly connected to a magnetic ring 52, and the arc surface of the connecting seat 2 is fixedly connected to a plurality of U-shaped rods 53, and the arc surface of the U-shaped rod 53 is rotatably connected to an iron plate 54, and one side of the iron plate 54 is attracted to the magnetic ring 52, and the sides of the plurality of iron plates 54 away from the magnetic ring 52 are fixedly connected to connecting ropes 55, and the plurality of connecting ropes 55 are divided into two groups, and the other end of each group of connecting ropes 55 is fixedly connected to a circular ring 56, and the circular ring 56 is pulled to drive the iron plate 54 with the help of the connecting rope 55. Rotate and disengage from the magnetic ring 52, the circular ring 56 can pull multiple iron plates 54 at the same time, the arc surface of the temperature sensing frame 3 is fixedly connected to two connecting rods 57 relative to the position below the two circular rings 56, and the other ends of the two connecting rods 57 are fixedly connected to abutment plates 58. When pulling the circular ring 56, the fingers are pressed against the abutment plates 58, and the abutment plates 58 provide more stress for the circular ring 56. The upper surfaces of several iron plates 54 are fixedly connected with clamping plates 59, and the lower surfaces of the clamping plates 59 are in contact with the magnetic ring 52. The rotation of the iron plate 54 drives the clamping plates 59 to fit with the magnetic ring 52, and the clamping plates 59 further limit the iron plate 54 to prevent it from sliding down.

[0032] like Figure 4As shown, the cleaning structure 6 includes a rotating rod 61, the inner wall of the rotating rod 61 is slidably connected to the fixed rod 4, the arc surface of the rotating rod 61 is fixedly connected to two extension rods 62, the arc surfaces of the two extension rods 62 are fixedly connected to scrapers 63, the lower surfaces of the scrapers 63 are slidably connected to the inner wall of the temperature sensing frame 3, and the two scrapers 63 are fixedly connected to a circular tube 64 on the side close to each other, the inner wall of the circular tube 64 is slidably connected to the arc surface of the fixed rod 4, the cross-section of the scraper 63 is a right-angled triangle, the extension rod 62 is located on the other side of the inclined surface of the scraper 63, and the inclined surface of the scraper 63 scrapes the deposited dust, and the scraper 63 with a right-angled triangle cross-section is used to better push the dust and connect the extension rod 62, the arc surface of the fixed rod 4 is fixedly connected to a circular plate 65, the lower surface of the circular plate 65 is slidably connected to the rotating rod 61, the rotating rod 61 rotates on the lower surface of the circular plate 65, and the circular plate 65 limits the rotation of the rotating rod 61 so that the scraper 63 always keeps in contact with the inner wall of the temperature sensing frame 3.

[0033] Working principle: when it is necessary to inspect and repair the thermal components of the base 1 and the connecting seat 2, first pull the circular ring 56, which can pull multiple iron plates 54 at the same time, then put another finger on the abutment plate 58, and then pull the circular ring 56 to the side away from the magnetic ring 52. At this time, the circular ring 56 can be used to abut on the abutment plate 58 during the pulling process, and the abutment plate 58 can provide more stress for the circular ring 56. The connecting rope 55 drives the iron plate 54 to rotate from the arc surface of the U-shaped rod 53 through the pulling of the circular ring 56. After the iron plate 54 is separated from the arc surface of the magnetic ring 52, the clamping plate 59 is separated from the magnetic ring 52. At this time, move the circular ring 56, and the connecting rope 55 drives the U-shaped rod 53 to move through the circular ring 56 with the help of the iron plate 54, and the connecting seat 2 is separated from the base 1 through the U-shaped rod 53. At this time, the components in the base 1 and the connecting seat 2 can be inspected, and then The inner wall of the temperature sensing frame 3 is cleaned by the cleaning structure 6. After the inspection is completed, the connecting seat 2 is moved to fit with the base 1, and then the iron plate 54 is rotated to fit with the magnetic ring 52 through the U-shaped rod 53. The clamping plate 59 is rotated to the upper surface of the magnetic ring 52 through the iron plate 54. The clamping plate 59 plays a role in further limiting the iron plate 54 to prevent it from sliding down. The magnetic ring 52 is then attracted to the iron plate 54 by magnetic force, so as to limit the connection seat 2 and the base 1. After the connection seat 2 and the base 1 are installed, the water droplets will fall directly through the base 1 and will not adhere to the connection seat 2. When a fire occurs during the detection process, on the one hand, a large amount of smoke is generated, and on the other hand, a large amount of heat is released during the combustion process. The ambient temperature rises sharply, causing the thermistor in the connecting seat 2 to undergo physical changes, thereby converting the temperature signal into an electrical signal and performing alarm processing.

[0034] When it is necessary to clean the dust deposited in the temperature sensing frame 3, first rotate the rotating rod 61 from the arc surface of the fixed rod 4. At this time, the rotating rod 61 rotates on the lower surface of the circular plate 65. The circular plate 65 limits the rotation of the rotating rod 61 so that the scraper 63 always keeps in contact with the inner wall of the temperature sensing frame 3. The extension rod 62 drives the two scrapers 63 to rotate in a circle through the rotating rod 61. The circular tube 64 rotates on the arc surface of the fixed rod 4 through the scraper 63. At this time, the two scrapers 63 scrape the dust deposited on the inner wall of the temperature sensing frame 3 during the rotation. At this time, the adsorption force of the scraped dust is weak, so the dust can be directly processed.
