[0019] In the following description, the example details are given so as to provide more in-depth understanding of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments. It should be understood that the specific embodiments are only used to explain the utility model, and are not used to limit the utility model.

[0020] It should be understood that when the terms "comprising" and / or "including" are used in the specification, they are meant to indicate the presence of stated features, integers, steps, operations, elements, or components but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, or groups thereof.

[0021] In the prior art, displacement sensors are generally coated with strong glue on the surface of their shells to achieve fixed installation. When the strong glue solidifies, the displacement sensor can be firmly attached to the flange plate of a new energy fan for gap detection. However, in the actual sensor installation process, it is found that before the strong glue solidifies, the displacement sensor will fall off due to wind blowing, vibration and other factors, and cannot be stably attached. Therefore, there is an urgent need for a more reasonable displacement sensor to solve the above technical problems.

[0022] Please refer to Figs. 1-3 The utility model discloses a kind of magnetic type flange plate gap detection displacement sensors, including support 1 and shell 2, support 1 is fixedly connected with shell 2 by connecting measuring rod, displacement sensor is equipped in shell 2, at least one magnetic attraction hole 3 is equipped on the surface of shell 2 and support 1, a magnet 5 is embedded in any magnetic attraction hole 3;The surface of shell 2 and support 1 equipped with magnetic attraction hole 3 is adhered to the surface of flange plate by smearing glue, and is simultaneously adhered to flange plate by magnet 5;In actual application scene, the support 1 and shell 2 of the utility model are fixedly installed on the flange plate of new energy fan, and the gap between flange plate on new energy fan is mainly detected, first, strong glue is smeared on the surface of support 1 and shell 2, then installed in the position on corresponding flange plate, and since flange plate is metal material, magnet 5 can help support 1 and shell 2 to play auxiliary fixing role, the adhesion of support 1 and shell 2 is effectively improved by magnetic attraction force, and dislocation and falling caused by external force impact, vibration or wind blowing and other factors are reduced, so that the sensor can be stably pasted, and wait for the solidification of strong glue.

[0023] The working principle of the utility model is:

[0024] First, strong glue is smeared on the respective adhesive surface 4 of shell 2 and support 1, which can be smeared on the adhesive surface 4 by dispensing, then shell 2 and support 1 are directly pressed and attached on flange plate, glue is diffused after being extruded, magnet 5 on shell 2 and support 1 generates magnetic attraction force, and is stably adsorbed on the surface of flange plate, auxiliary sensor is installed on flange plate until strong glue is dry and solidified, when sensor is damaged or needs to be maintained, tool is inserted into strip-shaped slot 41, and then sensor can be easily pried off.

[0025] In the embodiment, in order to improve the adsorption force, the magnet 5 is partially exposed outside the magnetic suction hole 3 and is flush with the surface of the shell 2 and the support 1, so that when the shell 2 and the support 1 are installed, the shell 2 and the support 1 can be tightly attached to the surface of the flange plate, and the magnetic suction force of the magnet 5 is effectively maintained.

[0026] In the embodiment, the surface of the shell 2 is also formed with a glue surface 4, which is used for applying strong glue, and the glue surface 4 can effectively provide the adhesive force and can also avoid that the glue damages the surface of the shell 2 when the shell 2 and the support 1 are pressed.

[0027] In the embodiment, the magnetic suction hole 3 is formed with an inner hole with a smaller radius than the magnetic suction hole 3, and the contact part of the magnet 5 with the end surface of the inner hole is fixed by applying epoxy resin, so that the magnet 5 is effectively fixed in the magnetic suction hole 3 and is prevented from falling out of the magnetic suction hole 3.

[0028] In the embodiment, the surface of the support 1 and the surface of the shell 2 provided with the magnetic suction hole 3 are flush, so that when installation is performed, the stability can be effectively maintained, the imbalance caused by the height difference between the support 1 and the shell 2 is avoided, and the support 1 and the shell 2 can be more closely attached to the flange plate.

[0029] In the embodiment, referring to Fig. 3 , the glue surface 4 is formed with staggered strip-shaped grooves 41, and when the sensor is bonded, the strip-shaped grooves 41 can provide a certain space gap between the sensor and the flange plate, so that when the sensor needs to be repaired or replaced due to damage, the sensor can be pried and removed by inserting a tool into the strip-shaped grooves 41, thereby avoiding the problem that the position sensor is completely bonded to the flange plate and is difficult or impossible to disassemble.

[0030] The advantage of the utility model lies in that:

[0031] The utility model adds the magnet auxiliary support and the shell to complete the process of glue bonding and adhesion, effectively reduces the problem that the position sensor is loosened and falls off due to external factors such as external force impact and vibration because the glue has not completely solidified.

[0032] The above disclosure is only several specific embodiments of the utility model, but the utility model is not limited to this, any change that can be thought of by any person skilled in the art should fall within the protection scope of the utility model.
