Description

Technical Field

[0001] The utility model belongs to the technical field of water conservancy project construction surveying and mapping, in particular to a water conservancy project construction surveying and mapping setting out device. Background Art

[0002] During the construction of water conservancy projects, surveying and mapping is a task that must be carried out in the early stage of construction. Through surveying and mapping, construction drawings can be drawn during the construction of water conservancy projects, such as river surveying and mapping, water pipe system surveying and mapping, and sewer well surveying and mapping.

[0003] During the surveying process, it is difficult to survey special locations such as sewers. Specifically, during the construction process, by mapping the sewer system, the underground drainage system can be effectively avoided during the construction excavation to avoid damage to the underground drainage system during the construction process. Sewers are located in the lower stratum. During the surveying process, it is difficult for the surveying probe to penetrate into the well for measurement.

[0004] Specifically, the most common sewer wells in water conservancy construction currently include vertical wells in the vertical strata and horizontal main wells connecting the vertical wells, through which surface water and groundwater flow. Therefore, during the construction process, it is necessary to survey and map the direction and length of the horizontal main well of the sewer well and draw drawings.

[0005] However, due to the special structure of the manhole, it is difficult for the mapping sensors and probes to enter the narrow horizontal main well during the mapping process. Currently, the only way to enter the well for measurement is to go down manually. The well is not only smelly, but also contains many gases and pollutants that are toxic and harmful to the human body. During the mapping process, the operators measure in the harsh manhole, which is not only difficult to measure due to the narrow underground environment, but also has a great impact on the health of the operators due to the pollutants and gases in the well.

[0006] At the same time, the lack of oxygen in the underground environment increases the risk of operations during the surveying process. Operators are very likely to faint due to lack of oxygen in an oxygen-deficient environment. Utility Model Content

[0007] Based on the above background, the purpose of the utility model is to provide a surveying and setting out device for water conservancy project construction.

[0008] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0020] The pulling wire passes through the pulling wire hole and the pulling wire tube.

[0021] Preferably, a plurality of support rollers supported on the inner side wall of the vertical well portion of the sewer well are hingedly connected to the support ring seat.

[0022] Preferably, the support roller comprises an articulated wheel rod hinged on the outer side wall of the support ring seat, and the support ring seat begins to have an articulated groove for articulating the articulated wheel rod;

The advantage of this method is that since the pulling lead pipe is kept at a distance from the inner wall of the well by the support ring seat-support abutment wheel, the defect of rope breaking caused by scratching against the well wall is avoided.

[0040] Example 1

[0041] like Figure 1-5 As shown, a water conservancy project construction surveying and laying out device includes a floating measuring mechanism 3 for floating in a sewer 1. Specifically, the floating measuring mechanism 3 is used to realize measurement in a narrow horizontal well environment during the floating flow process at the horizontal well position underground in the sewer 1.

[0042] Specifically, the floating measuring mechanism 3 includes a floating cylinder 31 spaced apart at the front and rear sides, and a cross connecting rod 32 is fixedly connected between the two ends of the floating cylinder 31, and a distance measuring probe 4 is installed on the left cross connecting rod 32. The distance measuring probe 4 is a conventional sensor for measuring distance disclosed in the prior art or a camera capable of measuring distance. Those skilled in the art can learn the specific structure and working principle of the distance measuring probe by referring to the technical manual.

[0043] During the floating operation in the water well, when encountering a high mud height, in order to avoid the defect that the floating tube 31 is stranded on the mud and cannot continue to float with the water flow, the above-mentioned floating measurement mechanism 3 also includes an obstacle-crossing mechanism installed on the cross-link 32 respectively; specifically, each cross-link 32 is respectively installed with a barrier-crossing mechanism on the front and rear sides, and with the cooperation of the barrier-crossing mechanism, it can achieve smooth passage over the mud obstacle and cross the mud obstacle.

[0044] Specifically, the above-mentioned obstacle-crossing mechanism includes a motor seat 33 fixedly mounted on the cross-link 32, which is installed in a conventional manner of existing motor sealing and waterproofing. A rotating motor is assembled and connected in the motor seat 33 (the rotating motor is sealed in a cavity in the motor seat 33, the rotating motor is not drawn in the figure, and the rotating motor is a conventional motor disclosed in the prior art. The protection of the rotating motor is achieved, specifically, the output shaft of the rotating motor is rotatably connected to the motor seat 33, and a sealed bearing is installed on the motor seat 33 to adapt to the output shaft of the motor, which plays a role in waterproofing and increases the flexibility of rotation). A swing arm 35 is fixedly assembled and connected on the output shaft of the rotating motor; the swing arm 35 rotates until it contacts the silt in the sewer 1, and the obstacle is crossed by the swing arm 35.

[0045] The structure of the swing arm 35 is as follows: the swing arm 35 comprises a horizontal arm portion fixedly mounted on the output shaft of the rotating motor, the horizontal arm portion is integrally formed with a vertically arranged support arm portion, and the rotating motor determines that the support arm portion is supported on the silt.

[0046] At the same time, in order to improve the stability of the support between the arm and the silt, a plurality of paddle boards 351 are fixedly connected to the arm.

[0047] During the working process, when it floats to the mud position in the horizontal well, the arm-paddle 351 is supported on the mud, and the rotating arm-paddle 351 structure forms a driving force between the mud and the floating tube 31. In the pushing mode, the floating tube 31 is continuously moved relative to the mud until it moves across the mud area.

[0048] Example 2

[0049] like Figure 1-5 As shown, based on the structure of Example 1, the water conservancy project construction surveying and layout device also includes a support and guide mechanism 2 supported at the vertical well position of the sewer well 1.

[0050] Specifically, during the working process, the floating measuring mechanism 3 is measured underground and pulled by pulling the lead wire, the purpose is to pull in the direction after the surveying and mapping is completed to realize the salvage of the floating measuring mechanism 3 from the underground well. At the same time, during the working process, the floating speed of the floating measuring mechanism 3 is controlled, and the operator on the ground realizes the control by pulling the pulling lead wire.

[0051] In order to ensure that the guide can be accurately pulled and lowered to avoid the pulling lead being out of control during the floating process, resulting in the floating buoy being out of control, the pulling lead pulled by the above-mentioned floating measurement mechanism 3 is supported and lowered through the supporting guide mechanism 2.

[0052] A pulling lead is hung on the right side cross-link 32 through a hinge structure (specifically, the hinge structure includes a hinged fixing seat 36 fixedly connected to the cross-link 32, the hinged fixing seat 36 is hinged with a hinged tongue plate 361, and the lower end of the pulling lead 34 is fixed on the hinged tongue plate 361), and the pulling lead is guided and released through the support guide mechanism 2.

[0053] The support and guide mechanism 2 includes a support ring seat 21, the center portion of which is fixedly connected to an inner diameter rod 22, the top of which is fixedly connected to a pulling lead wire tube 221, and the inner diameter rod is provided with a pulling lead wire hole connected to the pulling lead wire tube; the pulling lead wire 34 passes through the pulling lead wire hole 34 and the pulling lead wire tube 221.

[0054] At the same time, a plurality of support rollers supported on the inner side wall of the vertical shaft portion of the sewer 1 are hingedly connected to the support ring seat 21. The support rollers include an articulated wheel rod hingedly connected to the outer side wall of the support ring seat 21 (the articulated wheel rod is fixed on a pin hinged in an articulated groove 211), and an articulated groove 211 for articulating the articulated wheel rod is provided on the support ring seat 21. At the same time, a wheel frame 23 is fixedly assembled and connected to the outer end of the articulated wheel rod, and a support contact wheel 231 is rotatably connected to the wheel frame 23.

[0055] The bottom of the articulated groove is an open structure, while the top is a partition. Therefore, the articulated wheel rod is flipped to the position where the articulated wheel rod contacts the upper end of the articulated groove. At this time, all the articulated wheel rods maintain an upward tilted posture, so that they can be firmly supported on the side wall of the vertical well portion of the sewer well 1.

[0056] In actual working process, the length of the pulling guide tube 221 is changed according to the length of the vertical well part of the sewer well 1. Specifically, the height of the support ring seat 21-support abutment is controlled by pulling the guide tube 221 to ensure that it can be lowered to the lower end position supported in the vertical well part.

[0057] The construction method is: during the work, first pass the pulling lead 34 through the pulling lead pipe 221, then lower the buoy until it floats, and then hold the pulling lead pipe 221 to contact the support ring seat 21-support contact wheel 231 against the well wall, and the operator holds the pulling lead 34.

[0058] The advantage of this method is that since the pulling lead tube 221 is kept at a distance from the inner wall of the well by the support ring seat 21-support contact wheel 231, the defect of rope breakage caused by scratching against the well wall is avoided.

[0059] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
