Description

Technical Field

[0001] The invention relates to sensor installation, in particular to a sensor protection box suitable for angle steel. Background Art

[0002] When installing sensors on transmission towers for structural monitoring, due to the harsh outdoor environment, it is necessary to install a protective box for the sensor for protection. At the same time, since current sensors all have Internet of Things functions, the sensor's antenna and solar power supply (when necessary) functions must not be affected after the protection box is installed, and it is required to be able to check whether the sensor in the protection box is working properly during the later inspection. If necessary, the protection box should be able to be easily removed to maintain the sensor. In addition, most transmission towers and signal towers are built with angle steel, which is characterized by an "L"-shaped cross section. This special shape makes it difficult to install and seal the sensor protection box on the angle steel.

[0003] Since most of the current sensor protection boxes are in the shape of a cuboid, such as Figure 1 As shown, the sensors on the angle steel are generally installed at the junction of the two sides, which makes it difficult to install the protection box on the angle steel. In addition, it is currently generally bonded to the sensor base plane with glue, which is easy to seep water after long-term use in outdoor environments, causing the sensor to become damp. In order to avoid this situation, the current common practice is to make the protection box into an integrated shell, and then inject a sealing foaming agent into the internal space of the protection box after installation to achieve a durable protection effect of water and air isolation. However, the consequence of this operation is that the sensor is completely surrounded by glue, and once sealed, it is difficult to disassemble and repair.

[0004] After searching, the authorization announcement number CN210321717U discloses a tower tilt monitoring sensor mounting bracket, which specifically discloses: including: a base for carrying the sensor, a support fixture, an upper shell and a fixing member; the inner side of the upper shell is surrounded by a receiving cavity for accommodating the sensor, a plurality of first connection holes are provided on the shell edge of the upper shell, and the same second connection holes are also provided on the edge position of the base corresponding to the shell edge, and the fixing member fixes the upper shell to the base through the first connection hole and the second connection hole; the support fixture includes an inner support angle steel and an outer support angle steel for carrying the base, the inner support angle steel is connected to the base, and the outer support angle steel and the inner support angle steel are both provided with fixing holes, and the inner support angle steel is detachably connected to the tower and the outer support angle steel in sequence through the fixing holes by the fixing member. However, the sensor of the prior art is installed on the base, and the base extends outside the tower, and the sensor is easily damaged.

The baffle 2 is a transparent baffle 2, and the current status of the sensor can be directly observed through the baffle 2. The waterproof connector is installed on the baffle 2, and the communication line of the sensor is led out of the cavity through the waterproof connector.

The gaps between the frame 1, the baffle 2 and the sealing strip 3 are filled with sealant.

[0033] Taking the angle steel 4 matching the L70x70 specification as an example, the overall size of the protection box is 60x60x300 (unit: mm), the length of the protection box can be adjusted according to the size of the sensor, the thickness of the frame 1 is 2 mm, the thickness of the sealing strip 3 is 6 mm, and the thickness of the baffle 2 is 2 mm.

[0034] The installation process of this embodiment is as follows:

Then the frame 1 is inserted into the sealing strip 3 for installation and the sealing strip 3 and the frame 1 are sealed by injecting glue. Then the antenna or signal line of the sensor is led out from the waterproof connector. Then the plug-in baffle 2 is inserted into the slot of the sealing strip 3 against the frame 1, and the gap between it, the metal frame 1 and the sealing strip 3 is sealed with waterproof glue. In this way, the sensor is protected and disassembled for maintenance (only the sealant needs to be removed and the plug-in baffle 2 can be removed), which has a certain degree of versatility.

The baffle 2 is a transparent baffle 2, and the current status of the sensor can be directly observed through the baffle 2. The waterproof connector is installed on the baffle 2, and the communication line of the sensor is led out of the cavity through the waterproof connector.

[0040] One side of the sealing strip 3 is pasted on the angle steel 4, and the other side is provided with a slot, and the edges of the frame 1 and the baffle 2 are inserted into the slot, so that the sensor can be easily disassembled for maintenance. The gaps between the frame 1, the baffle 2 and the sealing strip 3 are filled with sealant.
