[0024] See Figures 1 to 3This utility model discloses a portable multifunctional wind measurement and detection device for nuclear power plants, including a telescopic adjustment assembly 10. The telescopic adjustment assembly 10 includes multiple telescopic rods 11 connected in sequence. Each telescopic rod 11 can be a round rod structure, with the inner diameter of each section larger than the outer diameter of the next section. Adjacent telescopic rods 11 are fixed by a fixing structure to adjust the overall length of the telescopic adjustment assembly 10. In its fully extended state, the telescopic adjustment assembly 10 has a length of 2 to 5 meters, ensuring that operators can easily reach ductwork areas below 5 meters. When used in conjunction with an A-frame ladder, it can comprehensively cover on-site detection needs, improving detection efficiency and accuracy. In its fully extended state, the telescopic adjustment assembly 10 has a length of 1 to 2 meters. Of course, the telescopic length of the telescopic adjustment assembly 10 can be adjusted according to requirements, and no specific limitation is made here. Preferably, the length of each telescopic rod 11 can be 0.8 to 1.2 meters.
[0025] The first section of the telescopic rod 11 is equipped with a grip and a temperature sensor 20, while the last section of the telescopic rod 11 is equipped with an indicator strip 30.
[0026] by Figure 1 For example, the first telescopic rod 11 can be the lowest telescopic rod 11 of the portable multi-functional wind measurement and detection device for the nuclear power plant, and the last telescopic rod 11 can be the highest telescopic rod 11 of the portable multi-functional wind measurement and detection device for the nuclear power plant.
[0027] In some embodiments, each section of the telescopic rod 11 is provided with a plurality of threaded holes 111 spaced apart along its axial direction, such as Figure 1 As shown, the number of threaded holes 111 in each section of the telescopic rod 11 can be relatively small. For example, threaded holes 111 can be provided on the circumferential sidewall of each section of the telescopic rod 11 near its axial ends, or as shown... Figure 2 As shown, the number of threaded holes 111 in each section of the telescopic rod 11 can be large, and a larger number of threaded holes 111 can improve the adjustment accuracy.
[0028] Furthermore, the fixing structure includes fasteners for connecting the threaded holes 111 of two adjacent sections of the telescopic rod 11. These fasteners include, but are not limited to, fastening screws or fastening bolts.
[0029] like Figure 4 As shown, in some embodiments, the fixing structure includes an adjusting sleeve 12, which is axially movable and fitted at the connection of two adjacent telescopic rods 11, and the adjusting sleeve 12 is provided with an elastic locking block 13.
[0030] The adjusting sleeve 12 can be generally cylindrical. The inner wall of the adjusting sleeve 12 can be provided with internal threads. The outer circumference of the telescopic rod 11 with the larger outer diameter of the two adjacent telescopic rods 11 can be provided with external threads. The external threads and internal threads cooperate with each other, so that the adjusting sleeve 12 can be installed on the telescopic rod 11 and the adjusting sleeve 12 can be adjusted along the axial direction of the telescopic rod 11. The inner side of the end wall of the adjusting sleeve 12 is provided with a first inclined surface 121. The number of locking blocks 13 can be one or two. The shape of each locking block 13 is generally arc-shaped. Each locking block 13 can be provided with a second inclined surface on the side facing the first inclined surface 121 of the adjusting sleeve 12. When the adjusting sleeve 12 axially presses the locking block 13, the first inclined surface and the second inclined surface press against each other, so that the locking block 13 radially locks the telescopic rod 11 with the smaller outer diameter. Of course, in some embodiments, the locking block 13 may be a silicone ring or a rubber ring. When the adjusting sleeve 12 axially presses the locking block 13, the locking block 13 deforms and radially presses the adjusting sleeve 12 and the telescopic rod 11 with a smaller outer diameter, so that the two adjacent telescopic rods 11 are relatively fixed.
[0031] Of course, in some embodiments, the fixing structure can also be a snap-locking structure, which is not specifically limited here.
[0032] In some embodiments, the telescopic rod 11 has at least two sections. Preferably, the telescopic rod 11 can have any number of sections greater than two, such as two, three, or four.
[0033] The telescopic pole 11 can be made of stainless steel or aluminum alloy. Stainless steel, such as 316L stainless steel, offers excellent corrosion resistance and mechanical strength, making it suitable for the working environment of offshore nuclear power plants. Alternatively, the telescopic pole 11 can be made of lightweight aluminum alloy.
[0034] Of course, the telescopic rod 11 can also be made of rigid insulating materials, such as phenolic plastics, polyurethane plastics, epoxy plastics, unsaturated polyester plastics, furan plastics, silicone resins, acrylic resins, and their modified resins. Understandably, the number of telescopic rods 11 and the materials used in their manufacture can be selected according to actual needs, and no specific limitations are made here.
[0035] In some embodiments, the telescopic rod 11 may be a solid structure or a hollow structure.
[0036] In some embodiments, the portable multi-functional wind measurement device for nuclear power plants further includes an insulating sleeve 40 fitted over at least part of the outer periphery of the grip portion, providing not only a secure grip but also insulation properties to ensure operational safety and suitability for various complex environments. Further, the insulating sleeve 40 may be, but is not limited to, a silicone glove or a rubber glove. The grip portion may be part of the first telescopic rod 11, meaning the operator can directly grip the first telescopic rod 11.
[0037] In some embodiments, the thermometer 20 is fixed to the first section of the telescopic rod 11 by tape, straps, or Velcro. The thermometer 20 includes, but is not limited to, an infrared thermometer pen, and can perform temperature measurement functions for on-site equipment and rooms. Preferably, the thermometer 20 can be fixed to the insulating sleeve 40 by tape, straps, or Velcro.
[0038] In some embodiments, one end of the indicator strip 30 is secured to the last section of the telescopic rod 11 by a strap or Velcro.
[0039] In some embodiments, the last section of the telescopic rod 11 is provided with at least two connecting rings, which are spaced apart along the axial direction of the last section of the telescopic rod 11. One end of the indicator strip 30 is connected to the at least two connecting rings by a strap or Velcro to improve the connection tightness.
[0040] In some embodiments, the indicator strip 30 is made of a lightweight fabric to ensure sensitive response even under weak airflow and rapid location of leaks. For example, the indicator strip 30 may be made of nylon. Alternatively, the indicator strip 30 may be made of polyester blends. Alternatively, the indicator strip 30 may be made of high-tech synthetic fibers, such as ripstop nylon, spandex, or aramid blends. Of course, the indicator strip 30 may also be made of other lightweight and abrasion-resistant materials; no specific limitations are specified here.
[0041] In some embodiments, the indicator strip 30 is triangular. The indicator strip 30 may be an isosceles triangle with a base length of 12 cm and a height of 18 cm. The flag surface of the indicator strip 30 may be printed with a prominent FHO logo for easy identification and recording. Preferably, the indicator strip 30 may be a blue, yellow, or red color for ease of observation.
[0042] like Figure 3As shown, in some embodiments, a hanging rope 50 is connected to the axial end wall of the first section of the telescopic rod 11. The hanging rope 50 can be an elastic rope. The hanging rope 50 can be easily looped around the wrist of the worker to prevent it from falling off. The hanging rope 50 also facilitates the attachment of the portable multi-functional wind measurement device for the nuclear power plant to a storage rack.
[0043] The portable multi-functional wind measurement device for nuclear power plants has a relatively simple overall structure, small size, and good portability.
[0044] This portable multi-functional wind measurement device for nuclear power plants has a wide range of applications and good practicality. It can be used to measure leaks in high-altitude ducts, detect leaks in pneumatic valves, detect positive and negative pressure at duct outlets, detect wind direction, detect duct air intake, and estimate the air volume in ducts.
[0045] This portable multi-functional wind detection device for nuclear power plants can effectively save manpower and resources. For leak locations that are high up or difficult to reach, the device can be easily accessed by adjusting the telescopic adjustment component 10, saving the work of carrying ladders or setting up scaffolding.
[0046] The portable multi-functional wind detection device for nuclear power plants is highly efficient. For leaks that are not visible to the naked eye on site, it can be detected through the indicator strip 30.
[0047] It is understood that the above embodiments only illustrate preferred embodiments of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model patent. It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model. Therefore, all equivalent transformations and modifications made within the scope of the claims of the present utility model should fall within the coverage of the claims of the present utility model.
