Description

Technical Field

[0001] The utility model relates to the technical field of environmental monitoring devices, and specifically refers to an environmental detection sampling device. Background Technique

[0002] With the development of society and the gradual improvement of people's living standards, people's requirements for the environment are gradually increasing. Among them, environmental protection has become the top priority. However, while protecting the environment, it is necessary to monitor the environment and the real-time status of environmental monitoring. Environmental monitoring refers to the systematic and continuous analysis of elements in the natural environment to evaluate environmental quality and understand the pollution status of the environment. At the same time, a sampling device is also needed for sampling.

[0003] Chinese Patent CN215065329U discloses a sampling and storage device for environmental detection, including a vehicle body, a push rod, and moving wheels; a push rod is provided on the left side of the vehicle body, moving wheels are provided at the bottom of the vehicle body, a storage box is provided above the vehicle body, several partitions are provided inside the storage box, a sampling tube storage grid is provided between the partitions, a support fixing plate is provided on the right side of the sampling tube storage grid, a sliding rod is provided in the middle of the support fixing plate, a sampling tube fixing plate is fixedly connected to the side of the sliding rod away from the support fixing plate, a sampling tube is provided in the middle of the sampling tube fixing plate, a connecting rod is provided in the middle of the sampling tube, a turntable is fixedly connected to the top of the connecting rod, a rotary blade is fixedly connected to the bottom of the connecting rod, a fixing strip is provided below the sliding rod, and a limiting rod is provided above the fixing strip. The utility model has a simple structure, wide application, strong practicability, and good development prospects. However, there are still defects that can be improved:

[0004] 1. The vehicle body of this utility model is directly provided with wheels below. When environmental detection sampling is required, drilling operations need to be carried out on the soil in the target area. However, as is well known, most land is uneven, which will not only cause the user's hands to vibrate during the walking process, but also make it difficult to keep horizontal during the operation process, greatly limiting the sampling operation site.

[0005] 2. The sampling tube is provided below the fixing plate of this utility model. It can be seen that after the soil in the target area is sampled by this utility model, since the sampling tube is directly provided below the fixing plate, it is not easy to pour out the soil in the sampling tube, indirectly increasing the steps for the user to obtain the sampled soil and greatly increasing the time cost of environmental detection. Content of the Utility Model

[0006] The technical problem to be solved by the utility model is to overcome the above problems and provide an environmental detection sampling device.

[0007] To solve the above technical problems, the technical solution provided by the present utility model is: an environmental detection sampling device, including a base plate. On the front and rear parts of both sides below the base plate, wheels with self-locking devices are provided. The wheels and the base plate are connected to each other through a shock absorption device. At the rear part of the top end of the base plate, a trolley handle is fixedly connected. In the middle of the top end of the base plate, a first through groove is opened. On both sides above the first through groove, base blocks are provided. The bottom end of the base block is fixedly connected to the base plate. On the top ends of both base blocks, support frames are fixedly connected. On the top ends of the adjacent sides of both support frames, a connecting plate is fixedly connected. On both sides of the bottom end of the connecting plate, hydraulic telescopic cylinders are fixedly connected. The bottom end of the hydraulic telescopic cylinder is fixedly connected to a receiving plate. The receiving plate is slidably connected to the support frame. In the middle above the receiving plate, a motor is provided. The motor is fixedly connected to the receiving plate through a motor seat. On the output shaft of the motor, a rotating shaft is fixedly connected. The bottom end of the rotating shaft passes through the receiving plate and extends below it. At the bottom end of the periphery of the rotating shaft, a fixed retaining ring is provided. On both sides of the fixed retaining ring, a quick-release device is provided to connect with the rotating shaft. At the bottom end of the fixed retaining ring, a drill bit is fixedly connected.

[0008] As an improvement, the shock absorption device includes a fixed block fixedly connected to the bottom end of the base plate. In the bottom end of the fixed block, a first groove is opened. In the lower parts of both side walls of the first groove, second grooves communicating with it are opened. In both second grooves, positioning shafts are slidably connected. On the adjacent sides of both positioning shafts, a shock absorption block is fixedly connected. The bottom end of the shock absorption block is fixedly connected to the wheel.

[0009] As an improvement, in the middle of the top wall of the first groove, a first spring is fixedly connected. The bottom end of the first spring is fixedly connected to a support block. The bottom end of the support block is fixedly connected to the shock absorption block. A first damper is arranged in the first spring. The top end and the bottom end of the first damper are respectively fixedly connected to the top wall of the first groove and the support block.

[0010] As an improvement, on the upper parts of both sides of the support block, second springs are hinged. On the separated ends of both second springs, they are hinged to the inner wall of the first groove. In both second springs, second dampers are arranged. The two ends of the second damper are respectively hinged to the support block and the inner wall of the first groove.

[0011] As an improvement, the quick-release device includes third grooves opened in the lower parts of both sides of the rotating shaft. On both sides of the fixed retaining ring, second through grooves for cooperating with the third grooves are opened. In both second through grooves, retaining ring rings are fixedly connected. In the retaining ring rings, fixed shafts are inserted.

[0012] As an improvement, spring three is sleeved on both of the fixed shafts on both sides. The separated ends of the two springs three are fixedly connected to the retaining ring. The closer ends of the two springs three are fixedly connected with a baffle, and the baffle is fixedly connected to one side of the periphery of the fixed shaft close to the rotating shaft.

[0013] The advantages of the present utility model compared with the prior art are as follows:

[0014] 1. The present utility model designs a shock absorption device. By arranging two groups of springs and dampers in the shock absorption device, the vibration of the whole device caused by the unevenness of the land is greatly reduced, making it not easy for the user's hands to be shaken during the traveling process. At the same time, it is also easy to maintain a certain balance on the uneven ground, that is, the sampled data will be more accurate.

[0015] 2. The present utility model designs a quick-release device.

[0029] The following further describes the present utility model in detail with reference to the accompanying drawings.

[0030] The working principle of the present utility model is as Figures 1 - 4 shown. An environmental detection sampling device includes a base plate 1. First, a first through groove 5 is formed in the middle of the top end of the base plate 1, and a drill bit 16 that cooperates with it is arranged in the first through groove 5. It should be noted here that the bottom end of the drill bit 16 passes through the first through groove 5 and is located below the first through groove 5. Similarly, the top end of the drill bit 16 is located above the first through groove 5. Immediately afterwards, a fixed retaining ring 14 is fixedly connected to the top end of the drill bit 16, a rotating shaft 13 is inserted into the fixed retaining ring 14, and both sides of the fixed retaining ring 14 are connected to the rotating shaft 13 through a quick-release device 15. At the same time, a bearing plate 10 is arranged above the fixed retaining ring 14, and the top end of the rotating shaft 13 passes through the middle of the bearing plate 10 and is fixedly connected to a motor 11. Here, the motor 11 is fixedly connected to the middle of the top end of the bearing plate 10 through a motor base 12. Then, hydraulic telescopic cylinders 9 are fixedly connected to both sides of the top end of the bearing plate 10. In addition, a connecting plate 8 is fixedly connected to the top end of the hydraulic telescopic cylinder 9. Then, support frames 7 are fixedly connected to both sides of the connecting plate 8. The bearing plate 10 is slidably connected to the support frames 7. Immediately afterwards, base blocks 6 are fixedly connected to the bottom ends of both support frames 7. It is worth noting that the base blocks 6 are fixedly connected to the base plate 1, and the two base blocks 6 are located on both sides of the first through groove 5. Secondly, a trolley handle 4 is fixedly connected to the rear part of the top end of the base plate 1. Wheels 2 with self-locking devices are arranged at the front and rear parts on both sides below the base plate 1. The wheels 2 and the base plate 1 are connected to each other through a shock-absorbing device 3.

[0031] The above-mentioned various structures together constitute the general appearance structure of an environmental detection sampling device of the present utility model.

[0032] To further explain the specific working principle of an environmental detection sampling device of the present utility model, the above-mentioned quick-release device 15 includes through grooves two 1502 opened on both sides of the fixed retaining ring 14. Then, grooves three 1501 for cooperating with the through grooves two 1502 are opened on both sides of the rotating shaft 13. Immediately afterwards, retaining ring rings 1503 are fixedly connected to the mutually remote sides of the inner walls of the through grooves two 1502 on both sides. Immediately afterwards, fixed shafts 1504 are inserted into both retaining ring rings 1503. It should be noted here that one end of the fixed shaft 1504 close to the groove three 1501 is located within the groove three 1501. To facilitate the pulling of the fixed shaft 1504, one ends of the two fixed shafts 1504 remote from each other are arranged outside the fixed retaining ring 14. At the same time, third springs 1505 are fixedly connected to the mutually close sides of the two retaining ring rings 1503. It should be noted here that the third springs 1505 are simultaneously sleeved on the fixed shafts 1504. Finally, baffles 1506 are fixedly connected to the mutually close ends of the two third springs 1505. The baffle 1506 is fixedly connected to the side of the periphery of the fixed shaft 1504 close to the rotating shaft 13.

[0033] The technical effect achieved by the technical solution composed of the above technical features is as follows: When it is necessary to remove the drill bit 16, the user first pulls out the two fixed shafts 1504 towards the mutually remote sides. When the fixed shafts 1504 are pulled outwards from the through grooves two 1502, the two baffles 1506 will synchronously displace towards the mutually remote sides. While the baffle 1506 is displacing, due to the existence of the retaining ring ring 1503, the baffle 1506 begins to squeeze the corresponding third spring 1505. When the two fixed shafts 1504 are pulled out from the corresponding grooves three 1501, the fixed shafts 1504 no longer fix the fixed retaining ring 14 on the rotating shaft 13. Then the user can remove the fixed retaining ring 14 together with the drill bit 16.

[0034] In order to further explain the specific working principle of an environmental detection sampling device of the present utility model, the shock absorption device 3 includes a fixing block 301 fixedly connected to the bottom end of the base plate 1. First, a first groove 302 is formed at the bottom end of the fixing block 301. Then, a first spring 306 is fixedly connected to the middle of the top wall of the first groove 302. The bottom end of the first spring 306 is fixedly connected to a support block 307. Immediately, in order to maintain stable operation, a first damper 308 is arranged inside the first spring 306, and the top end and the bottom end of the first damper 308 are respectively fixedly connected to the top wall of the first groove 302 and the support block 307. Immediately, upper parts on both sides of the support block 307 are hinged with second springs 309, and the separated ends of the two second springs 309 are respectively hinged to the inner wall of the first groove 302. At the same time, second dampers 310 are arranged inside the two second springs 309, and the two ends of the second dampers 310 are respectively hinged to the support block 307 and the inner wall of the first groove 302. Second grooves 303 communicated with the first groove 302 are formed at the lower parts of both side walls of the first groove 302. It should be noted here that the second grooves 303 are located below the second springs 309. Then, positioning shafts 304 are slidably connected inside the two second grooves 303. A shock absorption block 305 is fixedly connected to the adjacent sides of the two positioning shafts 304. The top end of the shock absorption block 305 is fixedly connected to the support block 307, and the bottom end of the shock absorption block 305 is fixedly connected to the wheel 2.

[0035] The technical effect achieved by the technical solution composed of the above technical features is as follows: When encountering a bumpy road section, the wheel 2 receives an upward impact force, which will first transmit the force upward to the shock absorption block 305 and cause the shock absorption block 305 to move upward. Immediately, the positioning shafts 304 on both sides of the shock absorption block 305 will move upward in the second grooves 303. At the same time, the shock absorption block 305 drives the support block 307 to move upward. Since the shock absorption block 305 moves upward, then the shock absorption block 305 will obliquely upward pull the second springs 309 and the second dampers 310 on both sides, and at the same time, the shock absorption block 305 upward compresses the first spring 306 and the first damper 308. The tensile forces received by the second springs 309 and the second dampers 310, as well as the compressive forces received by the first spring 306 and the first damper 308, jointly offset the impact force on the wheel 2.

[0036] The above has described the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the creative purpose of the present utility model, design similar structural manners and embodiments to this technical solution without creativity, they shall all fall within the protection scope of the present utility model.

[0037] In addition, the electrical components appearing in this text are all electrically connected to the external main controller and the 220V mains power supply. The main controller can be a conventional known device such as a computer for control. The hydraulic telescopic cylinder is connected to the external oil circuit. In the specific implementation manners of the present disclosure, the detailed descriptions of known functions and known components are omitted. To ensure the compatibility of the equipment, the operation means adopted are all consistent with the parameters of market instruments.
