In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0029] Example 1 Reference Figure 1-8 , which is the first embodiment of the present invention, provides an intelligent anti-interference ultrasonic level transmitter, the device comprising: The transmitter mechanism 100 includes a transmitter body 101, a protective cover 102 hinged to the top of the transmitter body 101, and a mounting cylinder 103 fixedly mounted to the bottom of the transmitter body 101, wherein the mounting cylinder 103 includes an outer layer 103a and an inner layer 103b mounted inside the outer layer 103a; A shock absorbing mechanism 200 for absorbing and dispersing vibrations, comprising a first damping material 201 located outside the inner layer 103b, a second damping material 202 coated on the outer surface of the first damping material 201, and a third damping material 203 coated on the outer surface of the second damping material 202; The protection mechanism 300 for resisting compression includes a plurality of reinforcing members 301 fixedly installed between the outer layer 103a and the inner layer 103b and used for absorbing vibration energy, a plurality of first reinforcing rings 302 fixedly installed on the outer surface of the inner layer 103b, and a plurality of second reinforcing rings 303 fixedly installed on the inner surface of the outer layer 103a; as well as, The dustproof sealing mechanism 400 includes a protruding strip 401 fixedly mounted on the top of the transmitter body 101 , a sealing plate 402 fixedly mounted on the outside of the protruding strip 401 , and an elastic rubber 403 fixedly mounted on the outside of the protruding strip 401 and used to apply elastic force to the sealing plate 402 .

[0030] Among them, through the cooperation between the first damping material 201, the second damping material 202 and the third damping material 203, it can be used to reduce shock and absorb energy for the parts inside the installation cylinder 103, solve the problem of the influence of external vibration on the parts, and achieve the effect of improving the protection of the parts. Through the cooperation between the reinforcement 301, the first reinforcement ring 302, the second reinforcement ring 303 and the connecting rod 304, it can be used to withstand the mechanical stress under high-pressure environment, solve the problem that the device is easily damaged under high-pressure environment, and achieve the effect of improving the stability of use under high-pressure environment. Through the cooperation between the protruding strip 401, the sealing plate 402 and the elastic rubber 403, it can be used to perform high-precision sealing on the inside of the protective cover 102 to prevent dust, moisture and other pollutants in the external environment from entering the inside of the protective cover 102 and affecting its normal operation. In summary, the protective cover 102 and the parts inside it are protected from three aspects of shock absorption, compressive strength and sealing to prevent the protective cover 102 from being disturbed by the outside world.

[0031] Specifically, the transmitter body 101 is rotatably connected to the protective cover 102 via an elastic hinge, and the elastic hinge is used for automatic closing of the protective cover 102 .

[0032] The protective cover 102 is automatically closed by an elastic hinge, and no additional manual operation is required to ensure closure, thereby ensuring that the protective cover 102 is in a closed state and the sealing of the top of the transmitter body 101 is guaranteed.

[0033] Furthermore, the outer side of the third damping material 203 contacts the inner wall of the outer layer 103a, and the contact surfaces among the first damping material 201, the second damping material 202 and the third damping material 203 are respectively bonded and connected.

[0034] Preferably, the protection mechanism 300 further includes a plurality of connecting rods 304 respectively fixedly mounted on the outside of the first reinforcement ring 302 and the second reinforcement ring 303 , and the ends of the connecting rods 304 are fixedly connected to the surface of the reinforcement member 301 .

[0035] The connecting rod 304 is used to strengthen the fixed connection effect between the reinforcing member 301, the first reinforcement ring 302 and the second reinforcement ring 303, thereby improving the overall reinforcement effect between the outer layer 103a and the inner layer 103b.

[0036] Furthermore, the size of the protruding strip 401 matches the size of the inner cavity of the protective cover 102 .

[0037] Furthermore, the surface of the sealing plate 402 is arranged to be an inclined surface, and the contact surface between the sealing plate 402 and the inner cavity of the protective cover 102 is an arc surface.

[0038] Among them, the surface of the sealing plate 402 is set to be an inclined surface to facilitate the closing of the protective cover 102, and the contact surface between the sealing plate 402 and the inner cavity of the protective cover 102 is set to an arc surface to improve the contact between the sealing plate 402 and the inner cavity of the protective cover 102, thereby improving the sealing performance.

[0039] Preferably, the material of the outer layer 103a is an aluminum alloy sheet, and the outer layer 103a is used for protection and corrosion resistance, and the material of the inner layer 103b is engineering plastic, and the inner layer 103b is used for impact resistance.

[0040] Among them, by setting the material of the outer layer 103a to an aluminum alloy sheet, it plays a protective role and has a certain anti-corrosion effect. By setting the material of the inner layer 103b to engineering plastic, it is used to protect the internally installed parts and avoid them from being damaged by impact.

[0041] Furthermore, the first damping material 201 , the second damping material 202 , and the third damping material 203 have different damping properties.

[0042] Among them, by setting the damping characteristics of the first damping material 201, the second damping material 202 and the third damping material 203 to be different, they are used to adapt to different vibration frequencies. Through the synergistic effect of multiple layers of materials with different damping characteristics, the overall vibration energy absorption effect is improved. Multiple layers of materials with different damping characteristics can be set.

[0043] During use, when the device is subjected to external vibration, the first damping material 201, the second damping material 202 and the third damping material 203 are used together to absorb vibration energy. When the device is used in a high-pressure environment, the reinforcement 301, the first reinforcement ring 302, the second reinforcement ring 303 and the connecting rod 304 cooperate to withstand the mechanical stress under the high-pressure environment.

[0044] In summary, through the cooperation between the first damping material 201, the second damping material 202 and the third damping material 203, it can be used to reduce shock and absorb energy for the parts inside the installation cylinder 103, solve the problem of the influence of external vibration on the parts, and achieve the effect of improving the protection of the parts. Through the cooperation between the reinforcement 301, the first reinforcement ring 302, the second reinforcement ring 303 and the connecting rod 304, it can be used to withstand the mechanical stress under high-pressure environment, solve the problem that the device is easily damaged under high-pressure environment, and achieve the effect of improving the use stability under high-pressure environment. Through the cooperation between the protruding strip 401, the sealing plate 402 and the elastic rubber 403, it can be used to perform high-precision sealing on the inside of the protective cover 102 to prevent dust, moisture and other pollutants in the external environment from entering the inside of the protective cover 102 and affecting its normal operation. In summary, the protective cover 102 and the parts inside it are protected from three aspects of shock absorption, compressive strength and sealing to prevent the protective cover 102 from being disturbed by the outside world.

[0045] Example 2 Reference Figure 6 and Figure 7 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that the reinforcement member 301 includes a reinforcement column 301a fixedly installed between the outer layer 103a and the inner layer 103b, a through hole 301b opened inside the reinforcement column 301a, and a plurality of damping grooves 301c opened on the surface of the reinforcement column 301a.

[0046] Among them, the through hole 301b is used to reduce the weight of the reinforcing column 301a and enhance its mechanical strength, thereby improving the reinforcement effect of the reinforcing column 301a. The damping groove 301c is used to change the local stiffness and damping characteristics of the reinforcing column 301a, thereby indirectly affecting the vibration energy absorption effect. The damping groove 301c can be set to a polygon. Because it has multiple sides and corners, it can provide more stress concentration points. The polygonal hole can increase the local damping characteristics of the material through its multiple sides and corners, thereby improving the vibration energy absorption effect. The more sides the polygon has, the better the damping characteristics. In addition, high-damping material can be filled in the damping groove 301c to improve the vibration energy absorption effect.

[0047] Furthermore, a sealing gasket is provided at the bottom of the protective cover 102 , and the shape of the sealing gasket matches the shape of the top of the transmitter body 101 .

[0048] The top of the transmitter body 101 can be better sealed by matching the outer shape of the sealing gasket with the shape of the top of the transmitter body 101 .

[0049] When in use, the through hole 301b is used to reduce the weight of the reinforcing column 301a and enhance its mechanical strength, and the damping groove 301c is used to improve the vibration energy absorption effect.

[0050] In summary, the reinforcement member 301 is used to enhance the mechanical strength between the outer layer 103a and the inner layer 103b and improve the vibration energy absorption effect.

[0051] Importantly, it should be noted that the construction and arrangement of the present application shown in a number of different exemplary embodiments are only exemplary.
