Description

Technical Field

[0001] The utility model belongs to the technical field of sensor protection, and in particular relates to a retractable sensor cover. Background Art

[0002] As a key component connecting the superstructure and substructure of the bridge, the elevated bearing has the important task of transmitting the reaction force and deformation borne by the bridge deck to the bridge piers.

[0003] In order to ensure the safety of the elevated support body during use, laser or infrared ranging sensors are usually used to monitor the displacement of the elevated support body at a short distance. When the existing sensors are detecting the elevated support body for a long time, some birds will stay on the sensors or build nests on the sensors. When the birds touch the sensors, dust will adhere to the detection window of the sensor. The adhered dust will cause measurement errors in the displacement monitoring of the sensor or cause equipment failure, making it inconvenient for people to use. Utility Model Content

[0004] The purpose of the utility model is to provide a retractable sensor cover with a simple structure and reasonable design in order to solve the above problems.

[0005] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0006] A telescopic sensor cover comprises a fixing frame, on which a protective cover is installed in the horizontal and vertical directions. The protective cover comprises a protective tube installed on the fixing frame through a fixing mechanism, a telescopic cover installed on one side of the protective tube and made of flexible rubber, and a protective plate installed on one side of the telescopic cover. A sensor is installed inside the protective tube, and a detection port is opened on one side of the protective plate to facilitate detection by a sensor detection head.

[0007] As a further optimization scheme of the utility model, the fixing mechanism includes two groups of fixing components, and the fixing components include an elastic band wrapped around the outside of the protective tube and the fixing frame, fixing blocks installed at both ends of the elastic band, and threaded holes opened in the fixing blocks, and the two threaded holes are locked between each other by bolts and nuts.

[0008] As a further optimization scheme of the utility model, a driving mechanism is installed on both sides of the protective tube, and the driving mechanism includes an elastic rod installed outside the protective tube, a fixing rope installed outside the elastic rod through a limiting mechanism, and a wind chime installed at the bottom of the fixing rope.

[0009] As a further optimization scheme of the utility model, the limiting mechanism includes two limiting plates installed on the outside of the elastic rod, and an annular block sleeved on the outside of the elastic rod and located between the two limiting plates, and one end of the fixing rope is fixedly connected to the outside of the annular block.

[0010] As a further optimization solution of the utility model, a fixing plate is installed at the bottom of the fixing frame, a base is installed at the bottom of the fixing plate, and mounting holes are installed at the four corners of the base.

[0011] As a further optimization solution of the utility model, a sleeve is installed on one side of the telescopic cover, the inner wall of the sleeve is provided with an internal thread, and the outside of the protective tube is provided with an external thread used in conjunction with the internal thread.

[0012] The beneficial effect of the utility model is that the utility model can protect the sensor through the protective tube, telescopic cover and protective plate, so as to prevent birds from hitting or touching the sensor, thereby reducing dust adhering to the sensor, and at the same time, with the help of the telescopic performance of the telescopic cover, the impact force exerted on the protective plate can be unloaded, thereby preventing the impact from directly colliding with the detection end of the sensor, thereby ensuring the service life of the sensor.

[0018] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] Example 1

[0020] like Figure 1 - Figure 3 As shown, a telescopic sensor housing comprises a fixing frame 2, the fixing frame 2 is provided with a protective cover in both horizontal and vertical directions, the protective cover comprises a protective tube 3 mounted on the fixing frame 2, a telescopic cover 4 mounted on one side of the protective tube 3 and made of flexible rubber, and a protective plate 5 mounted on one side of the telescopic cover 4, a sleeve 16 is mounted on one side of the telescopic cover 4, an inner wall of the sleeve 16 is provided with an inner thread, an outer surface of the protective tube 3 is provided with an outer thread used in conjunction with the inner thread, a sensor 6 is mounted inside the protective tube 3, a detection port 7 is provided on one side of the protective plate 5 for facilitating detection by a detection head of the sensor 6, and the protective tube 3 is mounted on the mounting frame 2 through two sets of fixing components The fixing component includes an elastic band 8 wrapped around the outside of the protective tube 3 and the fixing frame 2, the elastic band 8 is a stainless steel spring sheet, fixed blocks 9 installed at both ends of the elastic band 8, and threaded holes opened in the fixing blocks 9, the bolts pass through the two threaded holes in turn and are locked by nuts, and the fixing component is provided to facilitate the installation and disassembly of the protective tube 3, a fixing plate 1 is installed at the bottom of the fixing frame 2, a base 15 is installed at the bottom of the fixing plate 1, and mounting holes are installed at the four corners of the base 15, and an opening is opened on the side of the protective tube 3 away from the telescopic cover 4 for the sensor 6 connecting line to pass through, the protective tube 3 and the telescopic cover 4 can be circular or rectangular.

[0021] It should be noted that, when in use, this retractable sensor cover can install the sensor 6 inside the protective tube 3, and then screw the sleeve 16 onto the outside of the protective tube 3. When the protective cover needs to be installed on the fixing frame 2, the elastic band 8 is wrapped around the outside of the protective tube 3 and the fixing frame 2, and the bolts are passed through the two threaded holes in turn and tightened by the nuts. At this time, the protective tube 3 can be fixed on the fixing frame 2. The sensor 6 can be protected by the protective tube 3, telescopic cover 4 and protective plate 5, thereby preventing birds from hitting the sensor. At the same time, with the help of the telescopic performance of the telescopic cover 4, the impact force on the protective plate 5 can be unloaded, thereby preventing the impact from directly colliding with the detection end of the sensor 6, thereby ensuring the service life of the sensor 6.

[0022] Example 2

[0023] Combination Figure 1 , Figure 2 and Figure 4As shown, the difference between this embodiment and embodiment 1 is that elastic rods 10 are installed on both sides of the protective tube 3, and the elastic rods 10 are compression spring elastic rods. Two limit plates 13 are installed on the outside of the elastic rod 10, and an annular block 14 located between the two limit plates 13 is sleeved on the outside of the elastic rod 10. A fixing rope 11 is installed at the bottom of the annular block 14, and a wind chime 12 is installed at the bottom end of the fixing rope 11. Since the annular block 14 is sleeved on the outside of the elastic rod 10, the protective tube 3 will automatically be in a vertical state under the action of the gravity of the wind chime 12 regardless of whether it is installed horizontally or vertically, so that the user does not need to adjust it, which is more convenient for people to use.

[0024] The further improved feature of this embodiment is that when a bird contacts the elastic rod 10, the elastic rod 10 will shake, which will cause the wind chime to make a sound, thereby driving away the bird. At the same time, when the wind blows the wind chime 12, the wind chime 12 will also make a sound, and the flapping of the bird's wings can also make the wind chime make a sound, thereby better driving away the birds and reducing the situation of birds nesting on the cover, so that the sensor 6 can work better.

[0025] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
