DETAILED DESCRIPTION
[0028] Parts not explained in the following embodiments, such as how the detector body 3 measures the bearing capacity deflection of the house and how the leveling knob 2 adjusts the horizontality of the detector body 3, should be understood as existing technologies known or should be known to those skilled in the art.
[0029] Example 1
[0030] The housing bearing capacity deflection detector includes a detector body 3, which is an existing commercial product developed based on the scientific research projects such as the Provincial Market Supervision Bureau's science and technology project "Reinforced Concrete Assembly House Bearing Capacity Test Research", model JJZ-2, which is a key technology to effectively solve the long-distance micro-deformation measurement, and the detector body 3 provides technical protection for the safety of the house. The visual equipment of the detector body 3 generally includes an imaging system, a power system, a sensor and control system, a fill light system, and a sighting system.
[0031] The imaging system includes a black and white 2-megapixel high-speed industrial camera, which has a maximum sampling rate of 200 Hz and can capture images quickly and with high precision. The imaging system also includes a telescope 301 disposed at the front end of the high-speed industrial camera. The telescope 301 is a special industrial photogrammetry lens for accurately capturing images, and a special filter is installed on the telescope 301. The special filter is used to filter out unnecessary high-frequency signals, thereby improving the image quality of the telescope 301.
[0032] The sensing and control system includes a sensor disposed in the detector body 3, which is a two-axis high-precision tilt sensor that can accurately measure and calibrate the tilt angle of the device. The sensing and control system also includes an embedded control module, which includes a liquid crystal display screen for displaying basic parameters such as angle data of the tilt sensor and power information, and the embedded control module is the core of the detector body 3 for processing various sensor data and providing a user interface.
[0033] The fill light system includes a fill light 302 controlled by a dedicated LED driver module and a high-efficiency micro radiator, which is used to maintain the operating temperature of the fill light 302, thereby extending the service life of the fill light 302. The aiming system includes a laser, which can be used as a laser indicator and aiming tool to help users accurately locate and mark measurement points in complex environments. The power supply system is a device powered by a large-capacity lithium battery, thereby ensuring that the detector body 3 can work for a long time without an external power supply.
[0034] The imaging system, power system, sensor and control system, fill light system and aiming system work together to ensure that the detector body 3 can efficiently and accurately capture images and measure data in various environments. Overall, the design of the detector body 3 takes into account high-performance image capture capabilities, flexible data processing, portable power solutions and user-friendly interactive interfaces, and is very suitable for indoor and outdoor application scenarios that require high precision and high efficiency.
[0035] The utility model is an updated product developed based on the existing JJZ-2 type detector body 3, and can certainly be applied to other types of detector bodies 3. The structure and principle of the detector body 3 are not changed, but a supporting structure that is more suitable for industrial application environment is designed for it.
[0036] like Figure 1 and Figure 2 As shown, the detector body 3 is connected to the tripod 1 through the leveling knob 2. The leveling knob 2 can adjust the horizontality of the detector body 3 under the support of the tripod 1, so that the detector body 3 can stably detect the bearing capacity deflection of the house. The detector body 3 is provided with a shading component 4, a locking mechanism 5 and a telescope 301 protruding from one side of the detector body 3. The shading component 4 can be flipped around the periphery of the detector body 3 to block high-intensity light directly hitting the telescope 301 at different angles, and the high-intensity light includes but is not limited to high-intensity sunlight. The locking mechanism 5 can lock the flipping angle of the shading component 4, and then continuously block the high-intensity light at the corresponding angle, thereby reducing the impact of the high-intensity light source on the telescope 301, and then providing high-quality technical guarantee for the detection of house safety.
[0037] The shading assembly 4 includes a shading piece 404 and an extension column 403 which are arranged on the outer periphery of the detector body 3. The shading piece 404 and the extension column 403 are both parallel to the axis of the telescope 301. The shading piece 404 is slidably arranged on the extension column 403 along the axis of the telescope 301, so that the user can slide the shading piece 404 along the axis of the telescope 301 according to the specific situation, so that the shading piece 404 can provide low-light spaces of different sizes for the telescope 301. Both ends of the extension column 403 are fixedly connected with a rotating arm 402, and the free ends of the two rotating arms 402 are respectively rotatably connected to two supporting tubes 401. One of the two supporting tubes 401 is fixed on the detector body 3 around the outer periphery of the telescope 301, and the other supporting tube 401 is fixed on the side of the detector body 3 that is symmetrical to the telescope 301. The cooperation between the rotating arm 402 and the extension column 403 can make the shading member 404 rotate around the detector body 3, so that the shading member 404 can block the light from the high-intensity light source that is directly directed at the telescope 301 at different angles.
[0038] The shading member 404 is an arc-shaped plastic shading member 404, and the rotating arm 402 is made of elastic rubber. Therefore, on the basis of ensuring that the shading component 4 can block direct light at any angle, the weight of the shading component 4 is reduced, thereby reducing the influence of the shading component 4 on the weight of the detector body 3. At the same time, the shading member 404 and the rotating arm 402 can resist the impact force of the corresponding angle to a certain extent, thereby improving the protection of the detector body 3.
[0039] A handle 303 is fixedly connected to the top surface of the detector body 3. The handle 303 can facilitate the user to carry the detector body 3 and move it, so as to perform bearing capacity deflection tests on different houses at different locations. A dust cover 304 matching the telescope 301 is provided on the periphery of the detector body 3. The dust cover 304 is fixedly connected to a hanging rope sleeved on the handle 303. After the use of the detector body 3 is over, the dust cover 304 can be connected to the mirror of the telescope 301, so as to protect the telescope 301 and reduce the probability of damage to the telescope 301. The detector body 3 is arranged on the bearing platform, and the tripod 1 is detachably connected to the bearing platform, so as to facilitate the staff to disassemble and sub-assemble the detector body 3, so that the user can stably and safely carry the detector body 3, the tripod 1 and the leveling knob 2 over long distances.
[0040] The above is a basic embodiment of the utility model, and further improvements, optimizations and limitations can be made on the above basis to obtain the following embodiments:
[0041] Example 2
[0042] This embodiment further describes the structure of the locking mechanism 5 on the basis of the embodiment 1. Its main structure is the same as that of the embodiment 1, and is described in detail as follows: Figure 3As shown, in this embodiment, the locking mechanism 5 includes a locking assembly 501 and a locking plate 502 which are arranged away from the telescope 301. The locking assembly 501 includes a tensioning spring 5011 distributed axially along the support tube 401. One end of the tensioning spring 5011 is arranged in the support tube 401 and is fixedly connected to the detector body 3. The other end of the tensioning spring 5011 passes through the support tube 401 and is fixedly connected to the locking plate 502. The tensioning spring 5011 can make the locking plate 502 tend to move toward the support tube 401. The locking plate 502 is a cross plate with a cylinder fixed on the outer circumference, and after the cylinder of the locking plate 502 passes over the outer end surface of the support tube 401, it presses the rotating arm 402 under the action of the tensioning spring 5011. The force given by the tensioning spring 5011 to the locking plate 502 toward the support tube 401 can make the support tube 401 of the locking plate 502 press the rotating arm 402, so that the extension column 403 and the shading member 404 surrounding the detector body 3 can be positioned to the corresponding angle, and by setting the end surface of the rotating arm 402 pressed by the cylinder of the locking plate 502 to be a rough surface, the positioning of the shading member 404 is stabilized, thereby continuously blocking high-intensity light at the corresponding angle.
[0043] A guide post 5012 is distributed along the axial direction of the support tube 401. One end of the guide post 5012 disposed in the support tube 401 is fixed to the detector body 3. The other end of the guide post 5012 is slidably matched with the locking plate 502, so that the locking plate 502 can stably move along the guide post 5012 to stably press the rotating arm 402, thereby positioning the relative positions of the two light shielding members 404 to continuously block the direct light. The tension spring 5011 is disposed around the guide post 5012. The provision of the guide post 5012 enables the tension spring 5011 to stably pull the locking plate 502 toward the support tube 401, thereby improving the stability of the locking plate 502 pressing the rotating arm 402.
[0044] Example 3
[0045] This embodiment further describes the structure of the locking mechanism 5 on the basis of the embodiment 1. Its main structure is the same as that of the embodiment 1, and is described in detail as follows: Figure 4As shown, in this embodiment, the locking mechanism 5 includes a locking assembly 501 and a locking plate 502 which are arranged away from the telescope 301. The locking assembly 501 includes a clamping stud 5013 which is threadedly connected to the support tube 401. The clamping stud 5013 passes through one end of the support tube 401 and is fixedly connected to the locking plate 502. Rotating the locking plate 502 can rotate the clamping stud 5013. Rotating the clamping stud 5013 can adjust the distance between the locking plate 502 and the outer end surface of the support tube 401. The locking plate 502 is a cross plate with a cylinder fixed on the outer circumference, and after the cylinder of the locking plate 502 passes over the outer end surface of the support tube 401, it presses the rotating arm 402 under the action of the clamping stud 5013. When the adjustment stud is rotated to adjust the distance between the outer end surface of the support tube 401 and the locking plate 502, the force of the cylinder of the locking plate 502 pressing the rotating arm 402 can be adjusted, so that the position of the rotating arm 402 can be stably locked according to the specific situation, and then the corresponding positions of the extension column 403 and the shading member 404 can be locked to block direct light sources at different angles.
[0046] Example 4
[0047] This embodiment further describes the light shielding member 404 based on the embodiment 1. The main structure of this embodiment is the same as that of the embodiment 1. The specific description is as follows: Figure 1 and Figure 2 As shown, in the present embodiment, two shading members 404 are provided, and magnetic layers are provided on opposite sides of the two shading members 404. The arrangement of the two shading members 404 can block direct light rays from more angles, thereby improving the shading function of the shading members 404 on the telescope 301. The magnetic layer can combine the two shading members 404, thereby increasing the area of the shading members 404 that can block direct light rays from the telescope 301, thereby providing better conditions for adjusting the light intensity of the telescope 301. After the two shading members 404 are combined, they can also cooperate with the locking mechanism 5 to be positioned at the top of the detector body 3, and then can provide protection for the detector body 3 in case of sudden rainfall.
[0048] Example 5
[0049] This embodiment further describes the detector body 3 based on the embodiment 1. Its main structure is the same as that of the embodiment 1.

The setting of the fill light 302 can provide a certain light source to the telescope 301 based on optical imaging technology when insufficient light source affects the function of the telescope 301, thereby improving the accuracy of the detector body 3 in performing a building bearing capacity deflection test when the light source is insufficient. The fill light 302 is an infrared LED lamp equipped with a lens, so that the fill light 302 can provide necessary light in a low-light environment.
