Description

Technical Field

[0001] This utility model belongs to the field of portable freezing point measurement technology, specifically a portable freezing point measuring instrument for aircraft de-icing and anti-icing fluid. Background Technology

[0002] A freezing point meter is a professional instrument used to accurately measure the freezing point of liquids or semi-fluid substances. It is widely used in various fields such as aviation fuel, engine coolant, and antifreeze. Different models of freezing point meters adopt high-precision sensors, automatic control systems, and CFC-free cooling technology according to different application scenarios. They can measure temperatures from +80℃ to -90℃ and can achieve efficient testing of 40 samples per hour.

[0003] A patent with publication number CN204439541U discloses a handheld de-icing and anti-icing refractive index meter, comprising a cylinder, a light-inlet plate, a refracting prism, a reticle, and a variable eyepiece. The light-inlet plate and refracting prism are located at one end of the cylinder, with the light-inlet plate situated on the upper surface of the refracting prism. The variable eyepiece is located at the other end of the cylinder. A reticle is vertically arranged inside the cylinder, and three reading scales are provided on the reticle. This invention can directly test the refractive index of different types and concentrations of de-icing and anti-icing fluids, including aircraft de-icing and anti-icing fluids and pavement de-icing and anti-icing fluids. Through temperature compensation correction, the final measured value and the freezing point of the liquid are obtained, demonstrating excellent practical performance.

[0004] Currently, most existing aircraft de-icing point measuring instruments are portable handheld devices. While these instruments can be used to detect the icing point of closer parts of the aircraft, they cannot be used to detect the sides or higher parts of the aircraft. Furthermore, existing devices cannot address the issues of adjusting the length of the handheld measuring instrument or the height of the portable measuring instrument.

[0005] Therefore, a portable freezing point meter for aircraft de-icing and anti-icing fluid is proposed to address the above problems. Utility Model Content

[0006] To overcome the shortcomings of existing technologies and solve the above-mentioned problems, a portable freezing point measuring instrument for aircraft de-icing and anti-icing fluid is proposed.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: The portable freezing point tester for aircraft de-icing and anti-icing fluid of this utility model includes a storage box and multiple sets of docking extension rods movably sleeved on the inner wall of the storage box, a snap-fit ​​lock fixedly installed on the outer surface of the top of the storage box, and freezing point detectors and data control detectors movably sleeved on the inner wall of the storage box. A fixing block is provided on the top surface of the storage box, a hydraulic rod is fixedly connected to one side surface of the fixing block, a support arm is fixedly installed on the outer surface of the hydraulic rod, a semi-circular arc plate is provided on one end of the support arm, and the inner wall of the semi-circular arc plate is movably sleeved on the outer surface of the docking extension rod.

[0008] Preferably, a motor is fixedly installed on the inner wall of the snap-fit ​​latch, a docking sleeve is fixedly connected to the output end of the motor, the outer surface of the fixing block is fixedly connected to the inner wall of the docking sleeve, and limit grooves are formed on the inner walls of both sides of the docking sleeve.

[0009] Preferably, limit strips are fixedly connected to both sides of the support arm, the outer surface of the limit strips is movably sleeved on the inner wall of the limit groove, and a limit rod is fixedly connected to one end of the support arm.

[0010] Preferably, the other end of the limiting rod is movably sleeved on the inner wall of the fixing block, and a silicone anti-slip strip is fixedly connected to the inner wall of the semi-circular plate, with the outer surface of the silicone anti-slip strip adhering to the outer surface of the connecting extension rod.

[0011] Preferably, a pressure-resistant closure cover is oscillatingly connected to the top surface of the storage box, and a sponge pad is fixedly connected to the inner wall of the pressure-resistant closure cover.

[0012] Preferably, a semi-circular mating strip is fixedly connected to the inner wall of the storage box and the outer surface of the sponge pad, and the outer surfaces of the mating extension rod, the freezing point detector and the data control detector are movably sleeved on the inner wall of the semi-circular mating strip.

[0013] Preferably, a lateral anti-slip pad is fixedly connected to one side surface of the storage box, a rotating disk is fixedly installed on the bottom surface of the storage box, a docking ring is provided on the top surface of the pressure-resistant closing cover, and the outer surface of the data control detector is movably sleeved on the inner wall of the docking ring.

[0014] Preferably, a limiting groove is fixedly connected to the top surface of the pressure-resistant closing cover and at one side edge position, and a swing docking block is movably sleeved on the inner wall of the limiting groove, and one end surface of the docking extension rod is movably sleeved on the inner wall of the swing docking block.

[0015] The beneficial effects of this utility model are: This invention provides a portable freezing point tester for aircraft de-icing and anti-icing fluid. Multiple docking extension rods are extracted from the storage box. To detect the aircraft's altitude, these rods are docked together, and then the docking extension rods are snapped onto the surface of a swing docking block. A freezing point detector is then snapped onto the top of each docking extension rod. A hydraulic rod pushes one end of a fixed block, causing a support arm on one end of the hydraulic rod to move in the opposite direction. This causes a semi-circular plate on one end of the support arm to press against the outer surface of the docking extension rod, fixing its position and ensuring it is vertical. This allows for different lengths of docking extension rods to be added to detect the aircraft's side profile at different altitudes. This invention provides a portable freezing point tester for aircraft de-icing and anti-icing fluid. When the hydraulic rod extends and retracts the support arm, it slides inside the limiting groove two in conjunction with the limiting strips on both sides of the support arm, preventing the support arm from tilting during movement. This allows the support arm to directly adhere to the outer surface of the docking extension rod. The silicone anti-slip strip on the inner wall of the semi-circular plate increases the anti-slip force between the support arm and the docking extension rod surface. The support arm can be rotated at large angles by a motor, while small-distance and small-amplitude movements can be performed by stopping the motor and allowing the employee to perform small-amplitude hand swings. When the motor is working, it can position the swing angle of the docking extension rod, so that when the employee performs other tasks, the docking extension rod can be released to keep it in a vertical state, preventing the docking extension rod from tilting or collapsing due to the employee moving away.

Detailed Implementation

[0018] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Specific implementation examples are given below.

[0020] Please see Figure 1 - Figure 6 This utility model provides a portable freezing point tester for aircraft de-icing and anti-icing fluid, including a storage box 11 and multiple sets of docking extension rods 13 movably sleeved on the inner wall of the storage box 11, a snap-fit ​​lock 12 fixedly installed on the outer surface of the top of the storage box 11, a freezing point detector 14 and a data control detector 15 movably sleeved on the inner wall of the storage box 11, a fixing block 124 provided on the top surface of the storage box 11, a hydraulic rod 126 fixedly connected to one side surface of the fixing block 124, a support arm 127 fixedly installed on the outer surface of the hydraulic rod 126, a semi-circular arc plate 129 provided on one end of the support arm 127, and the inner wall of the semi-circular arc plate 129 movably sleeved on the outer surface of the docking extension rods 13; During operation, multiple docking extension rods 13 are extracted from the storage box 11. As needed, the aircraft's altitude is detected, and the multiple docking extension rods 13 are docked. After docking, the docking extension rods 13 are snapped onto the surface of the swing docking block 115. At this time, the freezing point detector 14 is snapped onto the top of the docking extension rod 13. Then, the hydraulic rod 126 pushes one end of the fixing block 124, causing the support arm 127 on one end of the hydraulic rod 126 to move in the opposite direction. The semi-circular plate 129 on one end of the support arm 127 is pressed against the outer surface of the docking extension rod 13, and the position of the docking extension rod 13 is fixed, so that the docking extension rod 13 is in a vertical state. This achieves the situation of changing the length of the docking extension rod 13 by adding different numbers of docking extension rods 13 to detect the side of the aircraft at different heights. Once the docking extension rod 13 is fully positioned, the hydraulic rod 126 retracts the support arm 127, causing the semi-circular plate 129 to move away from the surface of the docking extension rod 13. By having an employee hold the docking extension rod 13 and swing it back and forth, the freezing point detector 14 can be placed close to the surface of the aircraft to measure the temperature and processing status of the aircraft surface at close range.

[0021] Furthermore, such as Figure 1 - Figure 3 and Figure 5 - Figure 6 As shown, a motor 121 is fixedly installed on the inner wall of the snap-lock 12. A docking sleeve 122 is fixedly connected to the output end of the motor 121. The outer surface of the fixing block 124 is fixedly connected to the inner wall of the docking sleeve 122. Limiting grooves 123 are opened on the inner walls of both sides of the docking sleeve 122. Limiting strips 128 are fixedly connected to the two sides of the support arm 127. The outer surface of the limiting strip 128 is movably sleeved on the inner wall of the limiting groove 123. A limiting rod 125 is fixedly connected to one end of the support arm 127. The other end of the limiting rod 125 is movably sleeved on the inner wall of the fixing block 124. A silicone anti-slip strip 1210 is fixedly connected to the inner wall of the semi-circular plate 129. The outer surface of the silicone anti-slip strip 1210 is attached to the outer surface of the docking extension rod 13.

[0022] During operation, when the hydraulic rod 126 extends and retracts the support arm 127, the limiting strips 128 on both sides of the support arm 127 slide inside the limiting groove 123, preventing the support arm 127 from tilting during movement. This allows the support arm 127 to directly adhere to the outer surface of the connecting extension rod 13. The silicone anti-slip strips 1210 on the inner wall of the semi-circular plate 129 increase the anti-slip force between the support arm 127 and the surface of the connecting extension rod 13. The motor 121 can rotate the support arm 127 at large angles, while small-distance and small-amplitude movements can be stopped by the motor 121, allowing the employee to perform small-amplitude hand swings. When the motor 121 is working, it can position the swing angle of the connecting extension rod 13, so that when the employee performs other tasks, the connecting extension rod 13 can be released to maintain its vertical position, preventing it from tilting or collapsing due to the employee moving away.

[0023] Furthermore, such as Figures 1 to 6 As shown, a pressure-resistant closing cover a1 is swayably connected to the top surface of the storage box 11. A sponge pad a2 is fixedly connected to the inner wall of the pressure-resistant closing cover a1. A semi-circular mating strip a3 is fixedly connected to the inner wall of the storage box 11 and the outer surface of the sponge pad a2. The outer surfaces of the mating extension rod 13, the freezing point detector 14, and the data control detector 15 are movably fitted onto the inner wall of the semi-circular mating strip a3. A lateral anti-slip pad 111 is fixedly connected to one side surface of the storage box 11. A rotating disk 112 is fixedly installed on the bottom surface. A docking ring 113 is provided on the top surface of the pressure-resistant closing cover a1. The outer surface of the data control detector 15 is movably sleeved on the inner wall of the docking ring 113. A limiting groove 114 is fixedly connected on the top surface of the pressure-resistant closing cover a1 and located at one edge. A swing docking block 115 is movably sleeved on the inner wall of the limiting groove 114. One end of the docking extension rod 13 is movably sleeved on the inner wall of the swing docking block 115.

[0024] During operation, after the measurement is completed, the docking extension rod 13 can be disassembled, and the docking extension rod 13, the freezing point detector 14, and the data control detector 15 can be snapped onto the surface of the semi-circular docking strip a3 inside the storage box 11. The semi-circular docking strip a3 is used to limit the position of the docking extension rod 13, the freezing point detector 14, and the data control detector 15. When the pressure-resistant closing cover a1 is closed, the semi-circular docking strip a3 on the inner surface of the pressure-resistant closing cover a1 can snap and limit the position of the docking extension rod 13, the freezing point detector 14, and the data control detector 15. At the same time, the sponge pad a2 on the outer surface of the semi-circular docking strip a3 elastically compresses the semi-circular docking strip a3, thereby increasing the compression and snapping force of the docking extension rod 13, the freezing point detector 14, and the data control detector 15.

[0025] Working principle: Multiple docking extension rods 13 are extracted from the storage box 11. As needed, the aircraft's altitude is detected, and the multiple docking extension rods 13 are docked. After docking, the docking extension rods 13 are snapped onto the surface of the swing docking block 115. At this time, the freezing point detector 14 is snapped onto the top of the docking extension rod 13. Then, the hydraulic rod 126 pushes one end of the fixing block 124, causing the support arm 127 on one end of the hydraulic rod 126 to move in the opposite direction. The semi-circular plate 129 on one end of the support arm 127 is pressed against the outer surface of the docking extension rod 13, fixing the position of the docking extension rod 13 so that the docking extension rod 13 is in a vertical state. This achieves the situation of changing the length of the docking extension rod 13 by adding different numbers of docking extension rods 13 to detect the side of the aircraft at different heights. Once the docking extension rod 13 is fully secured, the hydraulic rod 126 retracts the support arm 127, causing the semi-circular plate 129 to move away from the surface of the docking extension rod 13. The operator then holds the docking extension rod 13 and swings it back and forth, allowing the freezing point detector 14 to be placed close to the surface of the aircraft for close-range temperature measurement and processing. When the hydraulic rod 126 reciprocates the support arm 127, the limiting strips 128 on both sides of the support arm 127 slide inside the limiting groove 123, preventing the support arm 127 from tilting during movement. This allows the support arm 127 to directly adhere to the outer surface of the connecting extension rod 13. The silicone anti-slip strips 1210 on the inner wall of the semi-circular plate 129 increase the anti-slip force between the support arm 127 and the surface of the connecting extension rod 13. The motor 121 can rotate the support arm 127 at large angles, while small-distance and small-amplitude movements can be stopped, allowing employees to perform small-amplitude hand swings. When the motor 121 is working, it can position the swing angle of the connecting extension rod 13, so that when employees perform other tasks, they can release the connecting extension rod 13 to keep it in a vertical state, preventing it from tilting or collapsing due to the employee moving away.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
