[0002] In industrial automation and intelligent monitoring systems, pressure sensors play a vital role. They are widely used in various industrial equipment and pipeline systems to monitor pressure changes in real time and ensure the safe operation of the system. However, due to the complex and changeable industrial field environment, pressure sensors are often faced with shocks and vibrations from the external environment. These shocks and vibrations will not only affect the measurement accuracy and stability of the sensor, but may also cause damage to the sensor, thereby causing system failures and safety hazards. At present, although there are some protective structures for protecting pressure sensors on the market, these structures often have the following problems: First, the buffering protection effect is limited, and it cannot effectively absorb and disperse the external impact force, resulting in the sensor still being easily damaged; second, the structure is fixed and lacks flexibility, and it cannot adapt to pipeline systems of different lengths and installation environments. Therefore, the development of an impact protection structure for pressure sensors with multiple buffering protections and flexible and adjustable structure has become a technical problem that needs to be solved urgently.

DETAILED DESCRIPTION

[0018] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0019] Example

[0020] like Figure 1-Figure 3 As shown, an embodiment of the present invention provides an impact protection structure for a pressure sensor, which is intended to protect the sensor body from external impact. The various components of the structure and their working methods will be described in detail below.

[0021] The impact protection structure mainly consists of a sensor body 1, a connecting plate 2, a telescopic rod 3, a connecting ring 1 4, a connecting ring 2 5, a locking piece 6, a shock absorbing piece 7 and a protective sleeve 8. The sensor body 1 is connected to the telescopic rod 3 through the connecting plate 2, and the bottom of the telescopic rod 3 is connected to the connecting ring 1 4. The connecting ring 1 4 and the connecting ring 2 5 are respectively located at the top and bottom of the pipe, and are tightly connected through the locking piece 6.

[0022] The sensor body 1 is the pressure sensor to be protected and is the core component of the impact protection structure. The connecting plate 2 is fixed on the surface of the sensor body 1 and is connected to the sensor body 1 as a bridge connecting the sensor body 1 and the telescopic rod 3. The telescopic rod 3 is installed at the bottom of the connecting plate 2 and can be extended and retracted as needed to adapt to pipes of different lengths. The connecting ring 1 4 and the connecting ring 2 5 are respectively located at the top and bottom of the pipe and are used to fix the entire impact protection structure on the pipe.

[0023] The locking member 6 includes a screw rod 61 installed at the bottom of the connecting ring 2 5 and a threaded ring 62 at the top of the connecting ring 1 4. The screw rod 61 is rotated to be threadedly connected with the threaded ring 62, thereby locking the connecting ring 1 4 and the connecting ring 2 5. The shock absorbing member 7 includes a spring 1 71, a contact piece 72 and a guide rod 73. The spring 1 71 is installed at the bottom of the connecting plate 2, and the contact piece 72 is located at the bottom of the spring 1 71 and contacts the connecting ring 1 4. The guide rod 73 passes through the connecting plate 2 and is connected with the contact piece 72 to ensure that the contact piece 72 moves in the vertical direction.

[0024] Protective sleeve 8: It is sleeved on the surface of the sensor body 1 to further protect the sensor body 1 from external impact. A spring 9 is installed on the inner top wall of the protective sleeve 8, and the spring 9 contacts the top of the sensor body 1 to increase the buffering effect of the protective sleeve.

[0025] The connecting piece 81, the fixing seat 21, the nut 22 and the bolt 23 are used to fix the protective sleeve 8 on the connecting plate 2. The connecting piece 81 is installed on the surface of the protective sleeve 8, and the fixing seat 21 is installed on the surface of the connecting plate 2. The protective sleeve 8 is rotated to insert the connecting piece 81 into the fixing seat 21, and then the bolt 23 and the nut 22 are used to fix the connecting piece 81 on the fixing seat 21.

[0026] Working principle:

[0027] When the pipeline is subjected to external impact, the impact force first acts on the connecting ring 1 4 and the connecting ring 2 5, and the impact force is transmitted to the telescopic rod 3 through the fixing effect of the locking member 6. The telescopic rod 3 expands and contracts according to the magnitude of the impact force, thereby absorbing part of the impact force. At the same time, the spring 1 71 in the shock absorber 7 is compressed to further absorb the impact force. The protective sleeve 8 and the spring 2 9 inside it also provide additional protection for the sensor body 1. The entire impact protection structure effectively reduces the impact of the sensor body 1 through multiple buffering and shock absorbing measures.
