Abstract
Description
Technical Field
[0001] This utility model relates to the field of overhead gas pipeline technology, and in particular to an overhead LNG pipeline support structure with settlement compensation adjustment. Background Technology
[0002] Currently, fire extinguishing tests on aerosol fire extinguishing products involve various environmental tests, such as high and low temperature performance and damp heat performance. After completing these environmental tests, the products need to have their thermocouple spacing verified according to XF499.1-2010 6.4.4, which specifies temperatures of 400℃, 200℃, and 75℃. The measured temperatures at each point should not exceed the specified values. Due to the diversity of products, including square and spun series, each series has different dimensions, and the thermocouple spacing varies from device to device. Therefore, it is necessary to continuously adjust the thermocouple installation position. Currently, there is no corresponding adjustment bracket to achieve this function. Therefore, it is necessary to design an adjustment bracket that allows for easy adjustment of the thermocouple installation position and has sufficient strength, capable of simultaneously measuring the nozzle temperature, shell temperature, and thermocouple spacing of the aerosol fire extinguishing device as specified in XF499.1-2010. Summary of the Invention
[0003] The purpose of this invention is to overcome the above-mentioned shortcomings and provide an adjustable support for testing aerosol fire extinguishing devices. This support allows for easy adjustment of the thermocouple installation position and has sufficient strength, facilitating the measurement of the nozzle temperature, shell temperature, and thermal gap of the aerosol fire extinguishing device.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an adjustable bracket for testing aerosol fire extinguishing devices, including a frame body, the frame body being detachably connected to an adjustable thermocouple mounting bracket at different heights in the vertical direction, a fire extinguishing device fixing bracket being provided at the bottom of the frame body, and the adjustable thermocouple mounting bracket including a mounting frame located in the middle, the mounting frame being detachably connected to the frame body through a connecting rod, and a through hole for inserting a thermocouple being provided on the surface of the mounting frame.
[0005] Preferably, the frame body is a vertically arranged cuboid frame structure, and the two sides of the frame body are provided with vertical sliding grooves that cooperate with the ends of the connecting rods.
[0006] Preferably, the end of the connecting rod is provided with an external thread that mates with the locking nut, and a washer is provided between the locking nut and the outer side of the slide groove. The surface of the washer is provided with a through hole for the connecting rod to pass through.
[0007] Preferably, the mounting frame is a rectangular frame structure with multiple through holes symmetrically arranged on both sides.
[0008] Preferably, the fire extinguishing device mounting bracket includes a steel plate vertically fixed to the bottom of the frame body, and the side of the steel plate is detachably connected to the top open mounting frame.
[0009] Preferably, the fixing frame is detachably connected to the side of the steel plate via a right-angle connecting plate, and the surface of the right-angle connecting plate is provided with small holes for inserting screws.
[0010] Preferably, the bottom of the steel plate is fixedly connected to an I-shaped square steel pipe.
[0011] The advantages of this invention are as follows: Traditional thermocouples cannot be fixed in their relative positions. This invention, with the aerosol fire extinguishing device mounting bracket in place, allows for adjustment of the thermocouple's height after the mounting bracket is adjusted. After inserting the thermocouple through the perforation, it can be fixed with cable ties or electrical tape, ensuring a completely fixed relative position. Furthermore, before measurement, the thermocouple's extension length can be clearly observed and adjusted from top to bottom to measure the temperature at the center of the spray. Multiple measurements can be performed, making it convenient and quick. Attached Figure Description

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0016] like Figure 1-3 As shown, an adjustable support for testing an aerosol fire extinguishing device includes a frame body 1. The frame body 1 is detachably connected to an adjustable thermocouple mounting bracket 2 at different heights in the vertical direction. A fire extinguishing device fixing bracket 3 is provided at the bottom of the frame body 1. The adjustable thermocouple mounting bracket 2 includes a mounting frame 2.1 located in the middle. The mounting frame 2.1 is detachably connected to the frame body 1 through a connecting rod 2.2. A through hole 2.3 for inserting a thermocouple is provided on the surface of the mounting frame 2.1.
[0017] Preferably, the frame body 1 is a vertically arranged cuboid frame structure, and the frame body 1 has vertically arranged grooves 1.1 on both sides that mate with the ends of the connecting rods 2.2. The grooves 1.1 allow the connecting rods 2.2 to rise or fall vertically in the frame body 1.
[0018] Preferably, the end of the connecting rod 2.2 is provided with an external thread that mates with the locking nut 2.4. A washer 2.5 is provided between the locking nut 2.4 and the outer side of the slide groove 1.1, and the surface of the washer 2.5 has a through hole for the connecting rod 2.2 to pass through. In this embodiment, after the connecting rod 2.2 slides and adjusts to the corresponding height position in the slide groove 1.1, the locking nut 2.4 can be tightened. The locking nut 2.4 moves closer to the slide groove 1.1 on the external thread surface of the connecting rod 2.2, thereby pressing the washer 2.5 against the outer side of the slide groove 1.1, and finally fixing the position of the connecting rod 2.2.
[0019] Preferably, the mounting frame 2.1 is a rectangular frame structure with multiple through holes 2.3 symmetrically arranged on both sides. In this embodiment, multiple thermocouples for measurement can be inserted into the through holes 2.3. Because the through holes 2.3 are symmetrically arranged, the multiple thermocouples are evenly distributed.
[0020] Preferably, the fire extinguishing device mounting bracket 3 includes a steel plate 3.1 vertically fixed to the bottom of the frame body 1, and the side of the steel plate 3.1 is detachably connected to the top-open mounting frame 3.2. A mounting frame 3.2 of appropriate size is selected, the aerosol fire extinguishing device is placed inside the mounting frame 3.2, and then the mounting frame 3.2 is connected to the steel plate 3.1.
[0021] Preferably, the fixing frame 3.2 is detachably connected to the side of the steel plate 3.1 via a right-angle connecting plate 3.3, and the surface of the right-angle connecting plate 3.3 has small holes for screws to pass through. In this embodiment, one side of the fixing frame 3.2 is welded to one end of the right-angle connecting plate 3.3, and the other end of the right-angle connecting plate 3.3 can be detachably connected to the steel plate 3.1 via screws.
[0022] Preferably, the bottom of the steel plate 3.1 is fixedly connected to the I-shaped square steel pipe 3.4. In this embodiment, the bottom of the steel plate 3.1 is welded to the top surface of the square steel pipe 3.4. This structure is extremely simple and can ensure that the steel plate 3.1 is vertical on the ground.
[0023] The working principle of this embodiment is as follows:
[0024] By selecting a fixed frame 3.2 of appropriate size, placing the aerosol fire extinguishing device inside the fixed frame 3.2, and then connecting the fixed frame 3.2 to the steel plate 3.1, the fixed installation process of the aerosol fire extinguishing device is achieved. After adjusting the connecting rod 2.2 to the appropriate height position by sliding it in the slide groove 1.1, the locking nut 2.4 can be tightened. The locking nut 2.4 moves closer to the slide groove 1.1 on the external thread surface of the connecting rod 2.2, thereby causing the washer 2.5 to press against the outside of the slide groove 1.1, ultimately positioning the connecting rod 2.2. Once the thermocouples are secured, insert multiple thermocouples for measurement into the perforation 2.3 and secure them with cable ties or electrical tape to complete the thermocouple installation process. Thermocouples need to be installed when measuring the first aerosol fire extinguishing device. When measuring other aerosol fire extinguishing devices, thermocouples do not need to be installed again. Simply adjust the installation height of the previous thermocouples. Specifically, loosen the locking nut 2.4, then adjust the height of the entire thermocouple adjustable mounting bracket 2 upwards or downwards, and then tighten the locking nut 2.4 again.
[0025] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
