[0002] When installing a hydrological long-hole immersion sensor, it is necessary to install it to a designated position below the ground with the help of the sensor's cable. The water level of a hydrological long-hole ranges from a dozen meters to thousands of meters. For hydrological long-holes with a water level buried at a depth of more than 300 meters, the installation is more difficult due to the heavy weight of the sensor and signal cable. When installing such sensors, it often requires multiple people to use complex tools such as fall chains, and due to the heavy weight, it is also difficult to fix the sensor after it is installed.

DETAILED DESCRIPTION

[0021] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1 and Figure 3As shown, a hydrological long observation hole immersion sensor installation device includes a plate group installed on a frame; the plate group includes a bottom plate 1 and a left plate 2 and a right plate 3 connected to both sides of the upper surface of the bottom plate 1, the bottom plate 1 is provided with a through hole for the cable to pass through, in this example, the bottom plate 1 and the left plate 2 and the right plate 3 are detachably fixed to the top of the frame by bolts; a tightening assembly is installed at the bottom of the plate group to tighten the cable, and a retractable wire assembly is installed at the top of the plate group to retract and release the cable and the sensor; the tightening assembly and the retractable wire assembly are equipped with a locking assembly to lock the position of the tightening assembly and the retractable wire assembly; the cable is wound along the retractable wire assembly and then passes through the tightening assembly and ends in the hydrological long observation hole.

[0023] like Figure 2-3 As shown, the tightening assembly includes a tightening rod 8, one end of the tightening rod 8 passes through the bottom of the left side plate 2 and is installed at the bottom of the right side plate 3, and the other end of the tightening rod 8 is connected to one end of the first tightening handle 9; the other end of the first tightening handle 9 is connected to the first tightening handle rod 10; the first tightening handle rod 10 is sleeved with the first twisting wire handle 11, and the lever balance principle is utilized through the first tightening handle 9 to make the length of the power arm greater than the resistance arm, thereby achieving the purpose of saving manpower.

[0024] A ring is connected to the middle of the tightening rod 8, one end of the ring is connected to the tightening rod 8 through a fork, and the other end is an opening. The fork can provide friction for the cable, and the cable can be removed or inserted through the opening without affecting the cable reeling and unreeling operation.

[0025] The wire reeling and winding assembly includes a rotating wheel 15, one end of which is mounted on the top of the left side plate 2 through a first rotating shaft 13; the other end of the rotating wheel 15 is mounted on the top of the right side plate 3 through a second rotating shaft 17, and rolling is achieved through the first rotating shaft 13 and the second rotating shaft 17; the second rotating shaft 17 is also connected to one end of a handle connecting rod 18, and the other end of the handle connecting rod 18 is connected to a second tightening handle rod 20; a second wire twisting handle 21 is sleeved on the second tightening handle rod 20, and similarly, through the handle connecting rod 18, the length of the power arm is made greater than the resistance arm, thereby achieving the purpose of saving manpower.

[0026] The first rotating shaft 13 is provided with a first bushing 12 , and the second rotating shaft 17 is provided with a second bushing 4 .

[0027] The outer edges of both ends of the rotating wheel 15 are respectively connected with a first baffle 14 and a second baffle 16 , which can effectively prevent the cable from slipping off the rotating wheel 15 during the process of retracting and releasing the cable.

[0028] The diameter of the rotating wheel 15 gradually decreases from both ends to the middle, which can prevent the cable from axially moving or deviating on the circumference of the rotating wheel 15.

[0029] The locking assembly includes a first latch 7 and a second latch 19; the first latch 7 passes through the first limit block 5 or the second limit block 6 and stops at the tightening rod 8, that is, the tightening rod 8 has a hole for the first latch 7 to be inserted; the first limit block 5 and the second limit block 6 are fixed on the left side plate 2, in this case fixed on the top and side of the tightening rod 8; the second latch 19 passes through the handle connecting rod 18 and stops at the right side plate 3, that is, on the handle connecting rod 18, and the right side plate 3 has a through hole for the second latch 19 to pass through.

[0030] The use of this device is as follows:

[0031] (1) Preparation before laying out:

[0032] like Figures 1 to 4 As shown, when laying out the wire, install the plate group on the frame so that the through hole on the bottom plate 1 is opposite to the position of the hydrological long-view hole, and the hydrological long-view hole is opposite to the ring in the middle of the tightening rod 8. The first pin 7 is inserted into the first limit block 5 and stops at the hole on the tightening rod 8. The cable of the sensor is wound around the rotating wheel 15 once (it can also be wound several times to increase the friction force), and then passed through the fork of the tightening rod 8, see Figure 4 This winding method generates beneficial friction between the cable and the fork of the tightening rod 8 during the unwinding process, thereby reducing manpower.

[0033] (2) Sensor laying process:

[0034] When releasing the wire, the handle connecting rod 18 and the right side plate 3 need to be locked with the second latch 19, and the free end of the cable is pulled to transport the cable to the hydrological observation hole. When the sensor is about to reach the specified position, the free end of the cable is tightened and the wire feeding is stopped. At this time, the first latch 7 on the tightening rod 8 is removed, and the first twisting handle 11 is shaken to make the cable wrap around the tightening rod 8 for about two turns. The first latch 7 is inserted back to lock the cable. At this time, the weight of the cable and the sensor in the hydrological observation hole is all borne by the tightening rod 8. Continue to release a certain length of cable, put a horseshoe buckle on this part of the cable, and pass it through a section of the positioning tube 22, and buckle it.

[0035] After the buckle is completed, tighten the free end of the cable, remove the first latch 7 on the tightening rod 8, and then shake the first twisting handle 11 to remove the wound cable from the tightening rod 8. After removal, insert the first latch 7 back into the tightening rod 8 and move the cable out of the opening of the tightening rod 8. Release the cable and release the positioning tube 22 to the position (at the hydrological observation hole), ensuring that there is about 2m of excess cable from the buckle to the end of the cable (for use when winding the cable), and the cable is released.

[0036] If the speed of paying out the wire is too fast, the tightening rod 8 can be rotated to form a certain angle with the horizontal plane (the first latch 7 is placed on the second limit block 6) to increase the friction between the cable and the tightening rod 8.

[0037] (3) Sensor winding process:

[0038] Wind the cable around the rotating wheel 15 for several turns. The specific winding method is the same as the unwinding method. Hold the free end of the cable and pull it backwards. At the same time, shake the second twisting handle 21. When the buckle rises to between the tightening rod 8 and the rotating wheel 15, pass the cable through the ring in the middle of the tightening rod 8, and shake the first twisting handle 11 to make the cable wind around the tightening rod 8 for about one turn, and insert the first pin 7 to lock the cable. At this time, the weight of the cable and sensor in the hydrological long observation hole is all borne by the tightening rod 8.

[0039] Then remove the tie buckle and positioning tube 22, remove the first latch 7, shake the first twisting handle 11, remove the cable wrapped on the tightening rod 8, and then insert the first latch 7 to lock the tightening rod 8. Continue to hold the free end of the cable and pull it back, and turn the second twisting handle 21 to complete the winding.

[0040] The present invention fixes the tightening rod and the rotating wheel by two pins, thereby solving the problem that the cables and sensors are heavy and the binding and unbinding operations of the positioning tubes are difficult during the process of paying out and taking up the cables; the cables are wound around the rotating wheel for multiple turns to increase the friction force, effectively reduce the force applied by personnel, and achieve the purpose of labor saving.
