Description

Technical Field

[0001] This utility model relates to the field of hydrogen determination probe technology, specifically a hydrogen determination probe protection device. Background Technology

[0002] As industrial facilities and equipment place increasingly stringent performance requirements on steel materials, many steel companies urgently need to improve steelmaking processes and enhance the controllability of the steelmaking process. Hydrogen content in steel is a crucial indicator affecting steel performance; therefore, online real-time measurement of hydrogen content in molten steel has become an important means of improving process control precision.

[0003] Chinese Patent Announcement No. CN221224736U discloses a protective device for a hydrogen determination probe. This device includes two support rods. A first clamping ring is fixedly installed on the surface of the two support rods away from the mounting ring. Two first springs are fixedly installed on the inner wall surface of the mounting ring away from the support rods. A second clamping ring is fixedly installed on the end of the two first springs away from the mounting ring. A sliding rod is fixedly installed on the outer wall surface of the mounting ring. A limiting plate is fixedly installed on the end of the sliding rod away from the mounting ring. A connecting ring is fixedly installed on the top surface of the vertical plate. Two connecting rods are fixedly installed between the connecting ring and the second clamping ring. This invention solves the problems of inconsistent thickness and material of the protective caps for existing hydrogen determination probes. If the protective cap is too thin, it melts when the probe contacts steel slag, easily causing the fiber cover to stick to slag and fail the test. If the protective cap is too thick, it dissolves too slowly in a low-temperature, viscous environment of molten steel, thus slowing down the probe response.

[0004] The aforementioned devices mainly focus on the specific structure of the hydrogen probe protection device, such as the connection method and positional relationship of components like support rods, clamping rings, and springs. This results in a relatively simple protection method for the hydrogen probe, which limits the device's usability in actual use. Utility Model Content

The end of the threaded rod is rotatably connected to an installation ring, and a first clamping plate is fixedly connected to the outer wall of the installation ring.

[0019] 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.

[0020] Please see Figures 1-5 This utility model provides a technical solution: a hydrogen determination probe protection device, including a first protective layer 1, a second protective layer 3 installed on the inner side of the first protective layer 1, the first protective layer 1 and the second protective layer 3 connected by a buffer layer 4, a probe body 2 installed inside the second protective layer 3, a clamping assembly for clamping the hydrogen determination probe installed inside the second protective layer 3, and a heat dissipation assembly for structural heat dissipation installed on the upper surface of the first protective layer 1; the protection assembly includes two fixing sleeves 5 that pass through the first protective layer 1, the second protective layer 3 and the buffer layer 4 in sequence, the two fixing sleeves 5 are respectively fixedly connected to the left and right sides of the outer wall of the first protective layer 1, the inner wall of the fixing sleeve 5 is provided with an internal thread 51, the inner wall of the fixing sleeve 5 is threadedly connected with a threaded rod 52, the end of the threaded rod 52 is rotatably connected to an installation ring 53, and the outer wall of the installation ring 53 is fixedly connected to a first clamping plate 54.

[0021] Through the above technical solution, the buffer layer 4 is filled between the first protective layer 1 and the second protective layer 3, thereby improving the impact resistance and shock resistance of the device. The multi-layer structure design can take into account impact resistance, corrosion resistance and sealing, ensuring the protective effect of the device. The structure can rotate the threaded rod 52 on the inner wall of the fixed sleeve 5, thereby driving the first clamping plate 54 to move in the horizontal direction, which can meet the clamping effect of hydrogen probes of different sizes.

[0022] Please see Figure 1 and Figure 5 The heat dissipation component includes multiple heat dissipation holes 6, which are arranged in a ring array around the center of the first protective layer 1 on the top wall of the first protective layer 1. A metal filter screen 61 is fixedly installed on the inner wall of the heat dissipation holes 6. Springs 7 are fixedly connected to the four corners of the outer wall of the first clamping plate 54, and the ends of the springs 7 are fixedly connected to the second clamping plate 8.

[0023] Through the above technical solution, multiple heat dissipation holes 6 are opened on the top wall of the first protective layer 1. At the same time, a metal filter 61 is installed inside the heat dissipation holes 6 to allow hydrogen to pass freely, but to block dust, water vapor and mechanical collisions, ensuring the normal operation of the probe, while avoiding the impact of high temperature on the use of the hydrogen determination probe.

[0024] Please see Figure 1 , Figure 2 and Figure 4 The first protective layer 1 is made of stainless steel, the second protective layer 3 is made of corrosion-resistant engineering plastic, and the buffer layer 4 is made of silicone. The buffer layer 4 fills the gap between the first protective layer 1 and the second protective layer 3.

[0025] Through the above technical solution, the first protective layer 1 and the second protective layer 3 are made of stainless steel and corrosion-resistant engineering plastic materials respectively, which can ensure that the device has good impact resistance and corrosion resistance; at the same time, the buffer layer 4 made of silicone material is filled inside the two protective layers, which can absorb vibration and improve the practicality of the device.

[0026] Working principle: A buffer layer 4 made of silicone material is filled between the first protective layer 1 and the second protective layer 3. The two protective layers and the buffer layer 4 together provide protection for the hydrogen determination probe. Simultaneously, the multi-layered structure further ensures the protection and sealing of the probe body 2. The hydrogen determination probe is placed inside the protective layer, and the operator manually rotates the threaded rod 52. The threaded rod 52 rotates within the inner wall of the fixed sleeve 5. Because the threaded rod 52 rotates during movement, and its end is rotatably connected to the inner wall of the mounting ring 53, the rotation of the threaded rod 52 allows for... The first clamping plate 54 moves back and forth in a translational state, so that the position of the clamping plate can be adjusted according to the hydrogen constant probe of different sizes to meet different clamping requirements. When the first clamping plate 54 is in contact with the outer surface of the probe body 2, the threaded rod 52 continues to rotate, and the second clamping plate 8 continues to move through the spring 7, thereby realizing adaptive clamping force and improving the clamping effect on the probe body 2. At the same time, during the use of this protective device, the heat dissipation hole 6 is embedded with a metal filter 61, which ensures airflow while ensuring dust prevention and heat dissipation, thereby preventing the probe from failing due to high temperature and ensuring the protective effect of the device.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
