It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0051] The present invention is further described in detail below in conjunction with the accompanying drawings:

[0052] See also Figures 1 to 8 The present invention provides an original soil sensor installation device, including a rod, a hoisting device 3, a connecting rope 6, a first cylinder 9, three solenoid valves 8, a second cylinder 17, a clamping cylinder 16, a clamping member 15 and a fixing member 21.

[0053] The hoisting device 3 is connected to one end of the rod, one end of the connecting rope 6 is connected to the hoisting device 3, and the hoisting device 3 can hoist the connecting rope 6. The first cylinder 9 is sleeved on the rod; the first solenoid valve is connected to the first cylinder 9, and the first solenoid valve is used for the telescopic control of the first cylinder 9; the second cylinder 17 is slidably sleeved on the rod, connected to the other end of the connecting rope 6, and is set in the opposite direction to the first cylinder 9; the second solenoid valve is connected to the second cylinder 17, and the second The solenoid valve is used for controlling the extension and retraction of the second cylinder 17; one end of the clamping cylinder 16 is connected to the second cylinder 17; the third solenoid valve is connected to the clamping cylinder 16, and the third solenoid valve is used to control the clamping and loosening of the clamping cylinder 17; one end of the clamping member 15 is connected to the other end of the clamping cylinder 16, and the other end can clamp the sensor, and the clamping cylinder 16 is used to drive the clamping member 15 to clamp the sensor or loosen the sensor; one end of the fixing member 21 is connected to the other end of the rod, and the other end is a tip. Among them, in this embodiment, the hoisting device 3 is a self-locking hand crank or an electric hoist, which mainly realizes the length control of the connecting rope 6. The connecting rope 6 can be a steel wire rope with a diameter of not less than 1.2 mm, or a nylon rope, a carbon fiber rope, etc.

[0054] A shaft is excavated in the installation area, and the diameter of the shaft is only required for the normal entry and exit of the installation device, which greatly reduces the diameter of the shaft, resulting in a sharp decrease in the amount of construction earthwork. After the shaft construction is completed, the rod is fixed inside the shaft by the fixing member 21. Since one end of the fixing member 21 is set as a pointed end, the installation device can be easily fixed at the bottom of the shaft.

[0055] The telescopic state of the first cylinder 9 is changed by the first solenoid valve, so that one end of the first cylinder 9 is in close contact with the inner wall of the shaft. Then, the hoisting action of the connecting rope 6 by the hoisting device 3 drives the second cylinder 17 to slide on the rod, and changes the position of the second cylinder 17 on the rod. When the set position is reached, the telescopic state of the second cylinder 17 is changed by the second solenoid valve, so that the telescopic rod of the second cylinder 17 is extended, and the clamping cylinder 16 and the clamping member 15 are moved toward the inner wall of the shaft, so that the sensor clamped by the clamping member 15 is in contact with the inner wall of the shaft, and then the telescopic rod of the second cylinder 17 is continuously controlled to extend, so that the sensor is inserted into the shaft wall. In the process of inserting the sensor into the shaft wall, in order to avoid the reaction force caused by the insertion, the first cylinder 9 is set in reverse phase, and one end of the first cylinder 9 is in close contact with the inner wall of the shaft. The reaction force provided by the first cylinder 9 is used to ensure that the installation device remains stable when the sensor is inserted.

[0056] Preferably, a plurality of raised strips 5 are provided on the side wall of the rod. Optionally, two raised strips 5 are symmetrically arranged at both ends of the rod to prevent the second cylinder 17 from rotating on the rod. At the same time, when the first cylinder 9 and the second cylinder 17 are provided with through holes for sleeve installation, it should be noted that grooves matching the raised strips 5 are reserved.

[0057] Preferably, a circular level 2 is also provided on the side wall of the hoisting device 3, and the circular level 2 is used to adjust the vertical state of the installation device to ensure that the installation device remains vertical.

[0058] Preferably, an infrared rangefinder 4 is also provided on one end of the winch device 3 connected to the rod member, and the infrared emitting end of the infrared rangefinder 4 is aligned with the second cylinder 17. The main function of the infrared rangefinder 4 is to determine the position of the second cylinder 17 to determine whether the sensor insertion position is accurate. When the infrared rangefinder 4 is not provided, it can also be determined by the length of the connecting rope 6, but it is not as accurate as when the infrared rangefinder 4 is provided.

[0059] Preferably, a handle 1 is provided on one end of the hoisting device 3 away from the rod, and the handle 1 is mainly used to facilitate the user to hold it to keep the installation device stable.

[0060] In the actual working process, the inventor also found that when encountering soil with low water content and high structural strength, the sensor is difficult to insert and is often damaged due to excessive pressure. Therefore, preferably, a nozzle 12 and a water pipe 7 are provided, the nozzle 12 is connected to the side wall of the clamping cylinder 16, and the water spraying end of the nozzle 12 is facing the clamping member 15, one end of the water pipe 7 is connected to the nozzle 12, and the other end is used to input water. When in use, the water pipe 7 is connected to an external water source. After the connection is completed, check whether there is water leakage at the water pipe 7 and the nozzle 12. If a water source cannot be obtained in the wild, a water tank can be prepared in advance to provide water.

[0061] At the same time, in order to accurately sense the state of the first cylinder 9 and the second cylinder 17, two sets of sensor units are set, and the two sets of sensor units are connected to the first cylinder 9 and the second cylinder 17 respectively. The sensor unit includes two in-place sensors 10 and a pressure sensor 11. The two in-place sensors 10 are connected to the telescopic rods and side walls of the first cylinder 9 and the second cylinder 17 respectively, and are used to detect the extension length of the telescopic rods of the first cylinder 9 and the second cylinder 17; the pressure sensor 11 is connected to the first cylinder 9 and the second cylinder 17, and is used to detect the pressure of the first cylinder 9 and the second cylinder 17. By observing the in-place sensor and the pressure sensor connected to the first cylinder 9, the end of the first cylinder 9 is closely attached to the side wall of the well wall, providing reaction force support during the insertion of the sensor. At the same time, by observing the pressure changes on the pressure sensor connected to the second cylinder 17, the changes of the sensor inserted into the soil can be observed at the same time. When the value is abnormal, it should be stopped immediately to prevent damage to the sensor.

[0062] The initial positions of the first cylinder 9 and the second cylinder 17 are in a retracted state, and the strokes of the first cylinder 9 and the second cylinder 17 are both set to 50-200 mm.

[0063] Preferably, a plurality of rotating shafts 13 and a plurality of gaskets 14 are also provided, and the plurality of gaskets 14 are connected to the clamping member 15 through the plurality of rotating shafts 13 in a one-to-one manner and can clamp one end of the sensor. For example, when the clamping member 15 is in the form of a clamping claw, after gaskets are provided at the two clamping ends of the clamping claw, the sensor can be effectively protected to prevent the sensor from being damaged by clamping.

[0064] When facing a deeper shaft, preferably, an extension rod 20 is provided, one end of which is connected to the end of the rod away from the hoisting device 3, and the fixing member 21 is connected to the rod through the extension rod 20, which can be in the form of a threaded connection. Specifically, an external thread 18 is provided on the rod, and an internal thread 19 matching the external thread 18 is provided inside the extension rod 20. The length of the extension rod 20 can be selected to be 500 mm. Specifically, a plurality of raised strips 5 are also provided on the extension rod 20, and after the extension rod 20 is connected to the rod, the positions of the raised strips 5 of the two are consistent.

[0065] Preferably, a PLC controller is also provided, and the PLC controller is connected to the first solenoid valve, the second solenoid valve and the third solenoid valve, wherein the first and second solenoid valves are telescopic solenoid valves, and the third solenoid valve is a clamping and releasing solenoid valve. The PLC controller changes the telescopic state of the first cylinder 9 and the second cylinder 17 and the clamping or releasing of the clamping cylinder 16 by controlling the conduction state of the first solenoid valve, the second solenoid valve and the third solenoid valve.

[0066] The signal data is collected and sent to the first cylinder 9, the second cylinder 17 and the clamping cylinder 16 through the solenoid valve 8, the in-position sensor 10 and the pressure sensor 11, and then sent to the PLC controller 23. The PLC controller 23 then controls the telescopic distance of the first cylinder 9, the telescopic distance of the second cylinder 17 and the clamping and releasing of the clamping member 15 provided on the clamping cylinder 16 according to the signal data sent by the first cylinder 9, the second cylinder 17 and the clamping cylinder 16, so as to grasp the sensor and then insert the sensor into the specified position.

[0067] In this embodiment, a temperature and humidity sensor is used as an example to illustrate the working process of the present invention as follows:

[0068] 1. Place the sensor into the gasket 14 on the clamp 15, and use the PLC controller 23 to clamp the sensor with the clamp 15.

[0069] 2. Choose whether to connect the extension rod 20 according to the placement position, and connect the fixing member 21 so that the length of the device can reach the bottom of the well and the tip of the fixing member 21 can be effectively inserted into the lower soil.

[0070] 3. Connect the water pipe 7 to the external water source. After the connection is completed, check whether there is water leakage between the water pipe 7 and the nozzle 12. If a water source is not available in the wild, a water tank can be prepared in advance to provide water.

[0071] 4. Insert the device into the soil. The insertion depth of the fixing member 21 should be no less than 20 cm. During the insertion, keep the device vertical by observing the circular level 2.

[0072] 5. When the device is vertical, control the first cylinder 9, and observe the position sensor 10 and the pressure sensor 11 to make the cylinder end of the first cylinder 9 close to the side wall of the soil, so as to provide reaction force support during the insertion process.

[0073] 6. By means of the hoisting device 3 and observing the reading of the infrared rangefinder 4, the position of the second cylinder 17 on the vertical rod is adjusted so that the sensor can be placed at the specified depth.

[0074] 7. Control the second cylinder 17 to extend and insert the sensor on the clamp 15 into the soil. During the insertion process, the pressure changes on the pressure sensor 11 should be observed, and the changes of the sensor inserted into the soil can be observed at the same time. When the value is abnormal, stop immediately to prevent damage to the sensor. During the insertion process, the operator needs to hold the handle 1 to fix the position of the device to prevent deviation.

[0075] 8. If the sensor is difficult to insert into a soil with low water content and high structural strength, in order to prevent the sensor from being damaged by excessive pressure, the water pipe 7 should be connected and water should be sprayed on the side wall of the original soil through the nozzle 12 to soften the soil. After the soil is softened, proceed to step 7.

[0076] The present invention installs the sensor on the original soil side wall by pushing the cylinder, thereby solving the problem of installing the sensor on the original soil side wall of a small-diameter vertical shaft. The present invention is particularly suitable for the installation of temperature and humidity sensors, and has the advantages of small construction earthwork volume, simple operation, and labor saving, thus ensuring the safety of the installers and saving time and effort.
