Description

Technical Field

[0001] This utility model relates to the field of rapid detection of solid waste pollution, and in particular to a mobile rapid screening device for slag and soil pollution. Background Technology

[0002] With the rapid pace of urban development, the amount of construction waste (hereinafter referred to as waste soil) has increased dramatically. Waste soil mainly consists of waste soil, mud, and engineering waste. Currently, the common treatment methods are landfill, recycling, and resource utilization. Because waste soil may contain pollutants such as heavy metals and organic matter, indiscriminate treatment without pollution screening may result in contaminated waste soil entering the treatment system, posing a threat to the environment and human health. In recent years, the country has increasingly emphasized solid waste pollution control, and has successively promulgated and implemented a large number of soil pollution prevention and control regulations. Therefore, rapid pollution screening technology for waste soil is an important control measure to respond to national environmental protection policies, strengthen pre-treatment management of waste soil, and prevent pollution before it occurs.

[0003] In existing technologies, the detection of construction waste typically involves setting up a construction waste sampling device on a gantry or a robotic arm, and then setting up a construction waste detection component on the gantry or at a predetermined location. The sampled construction waste is then moved to the construction waste detection component for detection, or the construction waste detection component is moved next to the sampling component to detect the sampled construction waste. After the detection is completed, the construction waste is moved to the construction waste recycling bin or pushed out of the sampling device so that the construction waste is returned to the construction waste truck.

[0004] The latest online construction waste detection system is the "Construction Waste Sampling and Detection System for Construction Waste Trucks" disclosed in the applicant's previously filed patent application with publication number CN115615739A (the same inventor as this utility model). This detection system has been put into application and has been widely promoted. Existing construction waste sampling and detection systems for construction waste trucks use a robotic arm connected to a sampling component. During construction waste detection, the sampling component is moved above the construction waste truck, and the sampling plate of the sampling component is inserted into the construction waste to collect a sample. After sampling, the robotic arm delivers the construction waste sample to the detection position, where a detection instrument is installed to test the sampled construction waste. After the test is completed, the robotic arm moves the sampling component to the construction waste sampling and collection container, where a bulldozing mechanism on the sampling component pushes the sampled construction waste out of the sampling plate and into the construction waste recycling component.

[0005] The main problems with the system at present include: 1) During testing, the movement range of the construction waste detection system is limited, and construction waste transport vehicles must drive onto the testing platform before testing can be carried out; 2) During testing, sampling is required first, then the system is moved to the detection component, and then tested. After the test is completed, the construction waste must be moved to the construction waste sampling and collection container, resulting in low testing efficiency and long time consumption; 3) The construction waste detection system has a complex structure, including a large number of robotic arms and servo motors, which is costly and complex to control. The detection equipment is not fully integrated, increasing the possibility of mechanical failure during the movement of each detection device to the detection position; 4) When the soil moisture is too high, the sampling component cannot collect enough samples, which may lead to the inability to complete the testing work. Utility Model Content

[0006] The purpose of this invention is to address the problems existing in the construction waste detection system described in the background art by providing a mobile rapid screening device for construction waste pollution.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A mobile rapid screening device for construction waste pollution includes a mobile device, a controller, a lifting drive assembly, a lifting base, and a rapid detection assembly. The controller is fixedly mounted on the mobile device. The lifting assembly and the rapid detection assembly are electrically connected to the controller. The lifting drive assembly is connected to the mobile device. The lifting base is fixedly connected to the lifting movable part of the lifting drive assembly. The rapid detection assembly is connected to the lifting base. The rapid detection assembly includes a housing, a base plate, an XRF detector, and a PID detector. The upper part of the housing has a connecting part that connects to the lifting base. The XRF detector main unit and the PID detector main unit are housed inside the housing. The lower end of the XRF detector main unit has an XRF drill bit that passes through a through hole in the base plate and extends below the base plate of the housing. The lower end of the PID detector main unit has a detection drill bit that passes through a through hole in the base plate and extends below the base plate of the housing.

[0009] In the above scheme, the rapid detection component is fixedly connected to the lifting seat via a sliding seat assembly. The sliding seat assembly includes an upper connecting seat, a slider, a sliding connecting seat, and a lower connecting seat. The upper connecting seat is fixedly connected to the lifting seat, the slider is fixedly connected to the upper connecting seat, and the sliding connecting seat is slidably connected to the slider. A reset component is provided on the sliding connecting seat to limit the relative sliding range between the sliding connecting seat and the slider. The lower connecting seat is fixedly connected to the sliding connecting seat, and the connecting part of the rapid detection component is fixedly connected to the lower connecting seat. By setting the sliding seat assembly, the slider and the sliding connecting seat can slide relative to each other. The slider is connected to the displacement driving device via the upper connecting seat, and the sliding connecting seat is connected to the detection component via the lower connecting seat. Therefore, the detection component can slide relative to the displacement driving device. With this setting, when the XRF drill bit and the detection drill bit of the rapid detection component are inserted into the slag, if they encounter rocks or other objects that generate large resistance, the relative sliding between the detection component and the displacement driving device can form a buffer, preventing damage to the XRF drill bit and the detection drill bit.

[0010] In the above scheme, a guide limiting groove is provided on the sliding connecting seat, and a limiting part that slides with the guide limiting groove is provided at the lower part of the slider. The two ends of the guide limiting groove extend to the front and rear sides of the sliding connecting seat respectively. The reset component includes two sets, and the two sets of reset components are respectively disposed on the front and rear sides of the sliding connecting seat. Each set of reset components includes a tension spring and two tension spring positioning posts. The two tension spring positioning posts are respectively fixedly connected to the sliding connecting seat and located on the left and right sides of the guide limiting groove. The two ends of the tension spring are respectively fixedly connected to the tension spring positioning posts. With this configuration, the slider and the sliding connecting seat can slide relative to each other. When the slag detection assembly performs slag detection, if there are hard objects such as stones in the slag and the resistance is large, the relative sliding between the sliding connecting seat and the slider can buffer the resistance and prevent damage to the XRF drill bit of the XRF detector and the detection drill bit of the PID detector. When the slider and the sliding connecting seat slide relative to each other, the sliding connecting seat can be elastically reset by the tension springs of two sets of reset components, so that the position between the slider and the sliding connecting seat returns to the initial state.

[0011] In the above scheme, two hinged bolts are respectively provided on the upper connecting seat and the lower connecting seat. The hinged bolts are respectively positioned corresponding to the left and right sides of the sliding connecting seat. The positions of the hinged bolts on the upper connecting seat correspond to the positions of the hinged bolts on the lower connecting seat. A steel wire rope connects the hinged bolts on the upper connecting seat and the corresponding hinged bolts on the lower connecting seat. By setting the hinged bolts and steel wire rope, the upper and lower connecting seats of the sliding connecting seat can be connected by the hinged bolts and steel wire rope, keeping them connected and preventing the slider from disengaging from the sliding connecting seat.

[0012] In the above scheme, the mobile device is a mobile vehicle, equipped with an adjustable connecting arm and an angle adjustment component for adjusting the angle of the connecting arm. The lifting drive component is mounted on the connecting arm and includes a mounting plate, a drive motor, a lead screw, and a lifting movable component. The mounting plate is connected to the connecting arm, the drive motor and lead screw are mounted on the mounting plate, the lead screw is vertically oriented, and fixedly connected to the output shaft of the drive motor. The lifting movable component is mounted on the lead screw, and the lifting seat is fixedly connected to the lifting movable component. This configuration allows the rapid testing component for construction waste to be mounted on the mobile vehicle. The mobile vehicle can be selected as needed, allowing it to move alongside the construction waste transport vehicle for rapid testing of the waste waste without requiring the vehicle to be driven to a predetermined testing platform, thus making waste waste testing more convenient. The connecting arm and angle adjustment component allow for better adjustment of the position of the rapid testing component above the construction waste vehicle, facilitating waste waste testing.

[0013] In the above scheme, the mobile device is a movable gantry frame, which includes a gantry frame, rollers at the bottom of the gantry frame, a gantry frame drive device for driving the gantry frame to move, and a horizontal displacement component on the top crossbeam of the gantry frame. The horizontal displacement component includes a horizontal drive component, a guide rail, and a sliding seat. The guide rail is arranged along the length of the top crossbeam. The horizontal drive component can drive the sliding seat to slide along the guide rail. The lifting drive component is arranged on the sliding seat and includes a mounting plate, a drive motor, a lead screw, and a lifting movable component. The mounting plate is fixedly connected to the sliding seat. The drive motor and the lead screw are arranged on the mounting plate. The lead screw is arranged in a vertical direction and is fixedly connected to the output shaft of the drive motor. The lifting movable component is arranged on the lead screw. The lifting seat is fixedly connected to the lifting movable component. The gantry frame drive device, the horizontal displacement component, and the lifting drive component are respectively electrically connected to the controller. This setup allows the rapid testing component for construction waste to be mounted on a movable gantry. The gantry drive mechanism moves the gantry alongside the construction waste transport vehicle to test the waste waste on board, eliminating the need to drive the vehicle to a designated testing platform and making waste waste testing more convenient. By incorporating a horizontal displacement component and a lifting drive component on the movable gantry, the rapid testing component can be moved above the construction waste transport vehicle and then lowered to test the waste waste on board, improving testing efficiency.

[0014] In the above scheme, the housing also includes a pH detector and a soil moisture detector. The main units of the pH detector and the soil moisture detector are housed within the housing and fixed to the base plate. Each detector has a detection probe at its lower end, which passes through a through-hole in the base plate and extends below the base plate. By incorporating the pH detector and the soil moisture detector, the pH and moisture content of the soil can be detected during soil testing, resulting in more complete data from the rapid testing component. Positioning the detection probes below the base plate allows for direct insertion into the soil during testing, leading to higher testing efficiency and more accurate results.

[0015] In the above scheme, a vertical fixed base plate is provided on the base plate, and the PID detector host is fixedly connected to the fixed base plate. An air pipe is provided at the lower end of the PID detector host, and a through hole is provided on the base plate. An air pipe connector is provided above the through hole, and the lower end of the air pipe is fixedly connected to the air pipe connector. The detection drill bit is fixedly connected to the lower surface of the base plate at a position corresponding to the through hole. The detection drill bit has a vent hole, which is connected to the PID detector host through the air pipe connector and the air pipe. With this configuration, when testing the slag, the detection drill bit breaks through the surface layer of the slag and inserts into the slag, allowing the gas in the slag to enter the PID detector host through the vent hole, air pipe connector, and air pipe on the detection drill bit. The PID detector host then detects the VOCs gas content in the slag.

[0016] In the above scheme, the XRF detector host includes an XRF protective cover, an X-ray module, and a semiconductor detector. The X-ray module and semiconductor detector are fixedly installed inside the XRF protective cover, which is fixedly connected to the bottom plate of the housing. The XRF drill bit includes a cylindrical section and a conical section. The conical section is fixedly connected to the lower end of the cylindrical section. A reflecting mirror to change the direction of X-rays is provided inside the cylindrical section. An X-ray outlet is provided on the side wall of the cylindrical section, and the position of the X-ray outlet corresponds to the reflecting mirror. With this configuration, the X-ray module emits X-rays, which are transmitted to the reflecting mirror to change direction and exit from the X-ray outlet on the side wall of the cylindrical section, entering the slag. The reflected rays enter the XRF drill bit in the opposite direction and are received by the semiconductor detector. The XRF detector host obtains the heavy metal content in the slag by analyzing and calculating the received reflected rays.

[0017] In the above scheme, several position sensors are provided on the outer wall of the housing. These position sensors are used to detect the depth to which the XRF drill bit of the XRF detector and the detection drill bit of the PID detector are inserted into the slag. By setting the position sensors, the depth to which the XRF drill bit of the XRF detector and the detection drill bit of the PID detector are inserted into the slag can meet the detection requirements.

[0018] This invention has the following advantages: 1) The mobile rapid screening device for construction waste pollution of this invention mounts the rapid detection component on a mobile device. When testing the construction waste on construction waste transport vehicles, the mobile device can be moved next to the vehicles for testing, eliminating the need to drive the vehicles to a fixed testing platform. This design makes construction waste testing more convenient. 2) The mobile rapid screening device for construction waste pollution of this invention eliminates the need for a robotic arm, and the structure of the rapid detection component is greatly simplified, eliminating the need for a sampling component and the operations of driving the sampling component to lift, open, and close, as well as pushing out the construction waste. The drive mechanism greatly simplifies the structure of the mobile rapid screening device for construction waste pollution, reduces costs, and simplifies the detection process. The XRF drill bit and detection drill bit at the lower end of the rapid detection component can be directly inserted into the construction waste to directly detect the heavy metal content and VOCs gas content in the construction waste, which can improve both detection efficiency and accuracy. 3) The mobile rapid screening device for construction waste pollution of this utility model does not require sampling of the construction waste, but directly inserts the XRF drill bit and detection drill bit into the construction waste to detect it. Therefore, even for construction waste with high moisture content, the detection can be completed smoothly. Attached Figure Description

Detailed Implementation

[0026] The technical solution of this utility model will be clearly and completely described below through embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] like Figure 1 and 2 As shown, the mobile rapid screening device for soil pollution of this utility model includes a mobile device 1, a controller 2, a lifting drive assembly 3, a lifting base 4, and a rapid detection assembly 5.

[0028] The mobile device 1 can be selected as needed; for example, the mobile device 1 can be a mobile vehicle or a movable gantry.

[0029] like Figure 1 As shown, in a first embodiment, the mobile device 1 can be an existing mobile vehicle with lifting and angle adjustment functions, such as a forklift, or it can be a specially designed mobile vehicle, such as an electric vehicle.

[0030] A connecting arm 11 is provided on the mobile vehicle for connecting the lifting drive assembly 3. The connecting arm 11 needs to be of the required strength. An angle adjustment assembly is provided on the mobile vehicle for adjusting the angle of the connecting arm 11. The angle adjustment assembly can be connected to the built-in controller of the mobile vehicle to control the angle of the connecting arm 11, or it can be electrically connected to the controller 2 to control the angle of the connecting arm 11, so that the rapid detection probe 5 moves to a suitable position above the muck transport vehicle.

[0031] The lifting drive assembly 3 is mounted on the connecting arm 11, for example, at the upper end of the connecting arm 11. The lifting drive assembly 3 includes a mounting plate 31, a drive motor 32, a lead screw 33, and a lifting movable component 34. The drive motor 32 can be a servo motor, and it is electrically connected to the controller 2. A flange seat 12 is provided at the upper end of the connecting arm 11, and the flange seat 12 is movably connected to the upper end of the connecting arm 11. The mounting plate 31 is fixedly connected to the flange seat 12 via a flange. The drive motor 32 and the lead screw 33 are mounted on the mounting plate 31. The lead screw 33 is arranged vertically and is fixedly connected to the output shaft of the drive motor 32. The lifting movable component 34 is mounted on the lead screw 33, and the lifting seat 4 is fixedly connected to the lifting movable component 34. In practical implementation, the lifting drive assembly 3 also needs to be equipped with some supporting components. These supporting components can be set according to existing technologies. For example, bearing seats and bearings can be set at both ends of the lead screw, with the lead screw and bearings rotating in coordination. Sensors can also be set next to the lead screw to control the stopping position of the lifting moving parts when they rise on the lead screw. A protective cover can also be set to house the lead screw, motor bearings, sensors, and other parts inside the protective cover.

[0032] This setup allows the rapid detection probe for construction waste to be mounted on a mobile vehicle. The mobile vehicle can then be moved alongside the construction waste transport vehicle to inspect the waste waste on board, eliminating the need to drive the truck to a designated inspection platform and making waste waste inspection more convenient. By installing an angle adjustment component and a lifting drive component on the mobile vehicle to adjust the angle of the connecting arm 11, the connecting arm 11 can be adjusted to a suitable angle, allowing the rapid detection probe to move above the construction waste transport vehicle. The lifting drive component then lowers the rapid detection probe to inspect the waste waste on the vehicle, improving inspection efficiency.

[0033] like Figure 2 As shown, in another embodiment, the mobile device 1 can adopt an existing movable gantry 13. Rollers 14 are provided at the bottom of the gantry 13, and a gantry drive device 15 is provided on the gantry 13 to drive the gantry 13 to move. The gantry drive device 15 can drive the gantry 13 to move linearly or turn.

[0034] A horizontal displacement assembly 16 is provided on the top crossbeam of the gantry frame 13. The horizontal displacement assembly 16 includes a horizontal drive component 161, a guide rail 162, and a sliding seat 163. The guide rail 162 is arranged along the length of the top crossbeam. The horizontal drive component 161 can drive the sliding seat 163 to slide along the guide rail 162. The lifting drive assembly 3 is arranged on the sliding seat 163. The lifting drive assembly 3 includes a mounting plate 31, a drive motor 32, a lead screw 33, and a lifting movable component 34. The mounting plate 31 is fixedly connected to the sliding seat 163. The drive motor 32 and the lead screw 33 are arranged on the mounting plate 31. The lead screw 33 is arranged in the vertical direction and is fixedly connected to the output shaft of the drive motor 32. The lifting movable component 34 is arranged on the lead screw 33. The lifting seat 4 is fixedly connected to the lifting movable component 34. The gantry frame drive device, the horizontal displacement assembly, and the lifting drive assembly are respectively electrically connected to the controller. Similarly, the lifting drive assembly can also be configured with the same accessories as described above. This setup allows for the rapid detection probe of construction waste to be mounted on a movable gantry. The gantry drive mechanism moves the gantry next to the construction waste transport vehicle to detect the waste waste on board, eliminating the need to drive the vehicle to a designated testing platform and making waste waste detection more convenient. By incorporating a horizontal displacement component and a lifting drive component on the movable gantry, the rapid detection probe can be moved above the construction waste transport vehicle and then lowered to detect the waste waste on board, improving detection efficiency.

[0035] Controller 2 is an electronic control device. Controller 2 is electrically connected to the drive motor 32 of the lifting drive assembly 3 to control the lifting and lowering movement of the lifting drive assembly 3. At the same time, controller 2 is also electrically connected to the XRF detector, PID detector, pH value detector, soil moisture detector, and other components inside the rapid detection probe 5, as well as the sensors on the detection probe, to process the detected signals, obtain detection data, and process the sensor signals to better control the movement of the lifting drive assembly.

[0036] The lifting seat 4 is used to install the rapid testing component 5. The structure of the lifting seat 4 can be designed according to needs. For example, the lifting seat 4 can be designed as a flange plate, which is fixedly connected to the lifting movable part 34 on the lifting drive component 3. As a preferred embodiment, a housing can also be provided on the lifting seat 4, and the upper components of the rapid testing component 5 can be placed inside the housing. This is achieved by placing the XRF drill bit, the testing drill bit, and the testing probe of the rapid testing component 5 below the housing.

[0037] like Figure 5 and 6 As shown, the fast detection component 5 includes a housing 51, an XRF detector, and a PID detector.

[0038] The housing 51 includes a cylindrical section and a base plate 52. The base plate 52 is fixedly connected to the bottom of the cylindrical section. Preferably, the base plate 52 is detachably fixed to the cylindrical section. The XRF detector host 54 and the PID detector host 55 are respectively fixedly connected to the base plate 52. A connecting part is provided at the top of the cylindrical section for connecting the lifting seat 4. With this arrangement, the housing 51 can provide protection for the internal components of the housing 51, while also facilitating the assembly and maintenance of the internal components. The connecting part at the top of the cylindrical section facilitates the connection between the fast detection component 5 and the sliding seat component 6.

[0039] Several position sensors 59 are provided on the outer wall of the housing 51. The position sensors 59 are used to detect the depth of the XRF drill bit 541 of the XRF detector and the detection drill bit 551 of the PID detector inserted into the slag. By setting the position sensors 59, the depth of the XRF drill bit 541 of the XRF detector and the detection drill bit 551 of the PID detector inserted into the slag can meet the detection requirements.

[0040] The XRF detector includes an XRF detector host 54 and an XRF drill bit 541. The XRF detector host 54 is disposed inside the housing 51 of the fast detection assembly 5 and fixed on the base plate 52. The XRF drill bit 541 is fixedly connected to the bottom of the base plate 52.

[0041] The XRF detector host 54 includes an XRF protective cover, an X-ray module, and a semiconductor detector. The XRF protective cover is fixedly connected to the base plate of the housing of the fast detection component. The X-ray module and the semiconductor detector are fixedly installed inside the XRF protective cover. The X-ray module is used to emit X-rays, and the semiconductor detector is used to receive secondary rays reflected from the slag. By analyzing and calculating the emitted X-rays and received secondary rays through the processor, the heavy metal content in the slag can be calculated.

[0042] The XRF drill bit 541 includes a cylindrical section and a conical section. The conical section is fixedly connected to the lower end of the cylindrical section. A reflective mirror is provided inside the cylindrical section to change the direction of X-rays. An X-ray outlet is located on the side wall of the cylindrical section, corresponding to the position of the reflective mirror. With this configuration, the X-ray module emits X-rays, which are transmitted to the reflective mirror to change direction and exit from the X-ray outlet on the side wall of the cylindrical section, entering the slag. The reflected rays enter the XRF drill bit in the opposite direction and are received by a semiconductor detector. The XRF detector host analyzes and calculates the received reflected rays to obtain the heavy metal content in the slag.

[0043] The working principle of an XRF detector is as follows: When atoms of heavy metal elements in a soil sample are irradiated with high-energy X-rays, they emit characteristic X-ray spectra with a certain energy. The energy of these characteristic X-ray spectra is measured by a semiconductor detector to analyze the concentration of heavy metals in the soil sample. Based on the principle that the pulse height of the semiconductor detector's output signal is proportional to the energy of the incident X-ray photons, when the semiconductor detector detects the characteristic X-ray spectrum of the soil sample, each channel of the semiconductor detector counts simultaneously, enabling simultaneous measurement of multiple elements. Qualitative and quantitative analysis is then performed by detecting the energy position and intensity of different characteristic X-rays.

[0044] The PID detector includes a PID detector host 55 and a detection drill bit 551.

[0045] A vertical mounting plate is provided on the base plate 52 of the housing of the rapid detection component 5. The PID detector host 55 is fixedly connected to the mounting plate. The connection method can be selected as needed. For example, a semi-circular clamp can be used to fix the PID detector host 55 to the mounting plate.

[0046] An air tube is provided at the lower end of the PID detector host 55. A through hole is provided on the base plate 52 of the rapid detection component 5. An air tube connector is provided above the through hole. The lower end of the air tube is fixedly connected to the air tube connector. The detection drill bit 551 is fixedly connected to the lower surface of the base plate at the position corresponding to the through hole. A vent hole is provided on the detection drill bit 551. The vent hole on the detection drill bit 551 is connected to the PID detector host 55 through the air tube connector and the air tube.

[0047] The working principle of a PID detector is as follows: A PID detector (photoionization detector) uses an ultraviolet (UV) lamp to ionize organic matter into positive and negative ions that can be detected by the detector (ionization). Under the action of an external electric field, the ions deflect, forming a weak current. Since the concentration of the gas being measured is linearly related to the photoionization current, the current signal is amplified and converted into a concentration value in "ppm" or "ppb". The PID detector has high sensitivity. Through high-energy ultraviolet light, it can ionize most organic matter and some inorganic matter. During the detection process, basic components in the air, such as nitrogen, oxygen, and carbon dioxide, are not ionized and do not interfere with the detection results. Therefore, it can accurately detect the VOCs content in construction waste.

[0048] like Figure 6As shown, as a preferred embodiment, a pH detector and a soil moisture detector can also be installed inside the housing 51. The pH detector main unit 56 and the soil moisture detector main unit 57 are installed inside the housing 51. The lower ends of the pH detector and the soil moisture detector are respectively equipped with detection probes 58, which pass through through holes in the base plate 52 and extend below the base plate 52. By installing the pH detector and the soil moisture detector, the pH value and moisture content of the soil can be detected during soil testing, making the data detected by the rapid testing component 5 more complete. By placing the detection probes 58 below the base plate 52, they can be directly inserted into the soil for testing, resulting in higher testing efficiency and more accurate results.

[0049] like Figure 3 As shown, in a preferred embodiment, the rapid testing component 5 can also be connected to the lifting seat 4 via the sliding seat component 6.

[0050] like Figure 4 As shown, the sliding seat assembly 6 includes an upper connecting seat 61, a slider 62, a sliding connecting seat 63, and a lower connecting seat 64.

[0051] The upper connecting seat 61 can be made of a flange plate with the required strength, and the upper connecting seat 61 is fixedly connected to the flange plate on the lifting seat 4 by bolts.

[0052] The slider 62 can be a T-shaped slider, and it is fixedly connected to the lower part of the upper connecting seat 61. The slider 62 needs to be made of a material with a certain strength, such as metal or alloy. The top of the slider 62 is fixedly connected to the upper connecting seat 61, for example, by using two bolts to connect the slider 62 to the upper connecting seat 61. The lower part of the slider 62 is provided with a limiting part, which is slidably connected to the sliding connecting seat 63.

[0053] The sliding connector 63 needs to be made of a material with a certain strength, such as metal or alloy. The sliding connector 63 is provided with a guide limiting groove. The limiting part of the lower part of the slider 62 is set in the guide limiting groove. The slider 62 is slidably connected to the sliding connector 63 through the limiting part at its lower part.

[0054] The sliding connecting seat 63 is provided with a reset component for limiting the relative sliding range between the sliding connecting seat and the slider. The reset component includes two sets, which are respectively disposed on the front and rear sides of the sliding connecting seat. Each set of reset components includes a tension spring 65 and two tension spring positioning posts 66. The two tension spring positioning posts 66 are respectively fixedly connected to the sliding connecting seat 63 and located on the left and right sides of the guide limiting groove. The two ends of the tension spring 65 are respectively fixedly connected to the tension spring positioning posts 66. With this configuration, the slider 62 and the sliding connecting seat 63 can slide relative to each other. When the fast detection component 5 performs soil detection, if there are hard objects such as stones in the soil and the resistance is large, the relative sliding between the sliding connecting seat 63 and the slider 62 can buffer the resistance and prevent damage to the XRF drill bit 541 of the XRF detector and the detection drill bit 551 of the PID detector. When the slider 62 and the sliding connecting seat 63 slide relative to each other, the tension springs 65 of the two sets of reset components can elastically reset the sliding connecting seat 63, so that the position between the slider 62 and the sliding connecting seat 63 returns to the initial state.

[0055] The lower connecting seat 64 is fixedly connected to the lower part of the sliding connecting seat 63. The lower connecting seat 64 can also be designed as a flange seat plate. The lower connecting seat 64 is fixedly connected to the top part of the housing 51 of the quick inspection component 5 by bolts.

[0056] Two hinge bolts 67 are respectively provided on the upper connecting seat 61 and the lower connecting seat 64. The hinge bolts 67 are respectively positioned corresponding to the left and right sides of the sliding connecting seat 63. The positions of the hinge bolts 67 on the upper connecting seat 61 correspond to the positions of the hinge bolts 67 on the lower connecting seat 64. A steel wire rope 68 connects the hinge bolts 67 on the upper connecting seat 61 and the corresponding hinge bolts 67 on the lower connecting seat 64. By setting the hinge bolts 67 and the steel wire rope 68, the upper connecting seat 61 and the lower connecting seat 64 of the sliding connecting seat 63 can be connected by the hinge bolts 67 and the steel wire rope 68, keeping them connected and preventing the slider 62 from disengaging from the sliding connecting seat 63.

[0057] Before using the mobile rapid screening device for construction waste pollution of this utility model, the rapid detection components need to be connected to the mobile device according to the aforementioned method. In addition, the connecting wires of the XRF detector, PID detector, position sensor, pH value detector and construction waste moisture detector should be connected to the controller respectively. The controller is connected to the power supply, data acquisition equipment and data display equipment. During testing, the mobile device moves to the side of the construction waste transport vehicle requiring testing. The controller moves the rapid testing component on the mobile device above the construction waste on the vehicle. The lifting drive component then lowers the rapid testing component, allowing the PID detector's drill bit, the XRF detector's head, and the pH and soil moisture detector's probes to be inserted into the soil. A position sensor detects the insertion depth. When the predetermined insertion depth is reached, the descent stops. The XRF, PID, pH, and soil moisture detectors respectively detect the heavy metal content, VOCs content, pH value, and humidity data in the soil. The detected data is transmitted to the controller, and then to the data acquisition and display equipment. After testing, the mobile device lifts the rapid testing component away from the construction waste and moves to the next construction waste transport vehicle requiring testing, repeating the same process. When the PID detector's drill bit, XRF detector's head, and the probes of the pH and soil moisture detectors are inserted into the soil to be tested using the moving device, if they encounter hard objects such as rocks and encounter significant resistance, the relative sliding of the slider on the sliding seat assembly with the sliding connecting seat can buffer and protect the PID detector's drill bit, XRF detector's head, and the probes of the pH and soil moisture detectors, preventing damage. Meanwhile, the reset components located on the front and rear sides of the sliding connecting seat can automatically reset the relative displacement of the slider and the sliding connecting seat, maintaining a stable positional relationship. The steel wire rope between the upper and lower connecting seats limits the relative range of motion between them, preventing the slider from detaching from the sliding connecting seat.
