Description

TECHNICAL FIELD

[0001] The utility model relates to electric power engineering survey process technical field, concretely is a kind of electric power engineering survey equipment. BACKGROUND

[0002] At present, general electric power engineering survey process is in turn: early preparation stage (collecting data, field reconnaissance, making survey scheme) → field survey stage (engineering geological mapping, exploration and sampling, in-situ testing, hydrogeological survey) → indoor test stage (soil sample test, rock sample test, water sample test) → data collation and report preparation stage (data collation, report preparation), exploration and sampling in the above-mentioned field survey stage generally adopt drilling, pit exploration and other means to explore, obtain the physical and mechanical properties of underground rock-soil and hydrogeological parameters;In drilling, half pipe can be used as an auxiliary tool, on the one hand, it can be used to protect the drilling tool in the drilling process, reduce the wear and damage of the drilling tool, for example, in some complex geological conditions, half pipe can prevent drill rod from being extruded and rubbed by rock, on the other hand, half pipe can be used to collect and save the rock core sample taken in the drilling process, by placing the rock core into half pipe, the integrity of the rock core can be better protected, which is convenient for subsequent geological analysis and research.

[0003] As known, half pipe is spliced by two parts, and its overall strength is generally lower than that of integrated drill rod structure, in drilling process, it is easy to be deformed or damaged by external force, which affects the service life of drill rod and the smooth progress of sampling work, however, the first end of the clamping spring of the assembled half pipe does not contact at present, and it is easy to be expanded and opened by external force, which affects the sealing and stability of half pipe, for example, in the sampling process of half pipe inner cavity, the sampled soil is accumulated and plugged into the half pipe inner cavity, and the accumulated sampled soil extrudes the inner wall of half pipe, the clamping force of the clamping spring is insufficient, and the first end of the clamping spring is not connected, so the assembled half pipe is easy to be separated and leaked, therefore, the electric power engineering survey equipment with high-stability half pipe is provided. CONTENT OF UTILITY MODEL

[0004] The utility model aims at solving the problem that the first end of the clamping spring of the assembled half pipe does not contact at present, and it is easy to be expanded and opened by external force, which affects the sealing and stability of half pipe, and provides the electric power engineering survey equipment.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0006] An electric power engineering survey equipment, comprising a half pipe, a plurality of annular clamping grooves coaxially arranged on the periphery of the half pipe, a splicing clamp or a rigid telescopic clamp is embedded and installed in each annular clamping groove, and the first end of the splicing clamp or the rigid telescopic clamp is connected with the tail end.

[0007] Preferably, the semi-composite pipe is symmetrically spliced ​​from semi-pipe one and semi-pipe two. Fixing strips are fixedly installed on the inner edges of the openings on both sides of semi-pipe one, and positioning grooves that correspond to and fit into the two fixing strips are provided on the inner edges of the openings on both sides of semi-pipe two.

[0008] Preferably, the splicing clamp includes a retaining spring and two arc-shaped connecting pieces, with the two ends of the two arc-shaped connecting pieces respectively connected to the beginning and end ends of the retaining spring.

[0009] Preferably, the snap ring has symmetrical notches at both ends, and symmetrical positioning holes are provided on the inner bottom and inner top surfaces of the notches. A fork-shaped spring sheet is provided between the two arc-shaped connecting pieces, and positioning pins that fit into the inner cavity of the positioning holes are fixedly installed at both ends of the two arc-shaped connecting pieces.

[0010] Preferably, the rigid telescopic clamp includes an arc-shaped base frame, an arc-shaped arm one, and an arc-shaped arm two. The central angles corresponding to the arc-shaped base frame, the arc-shaped arm one, and the arc-shaped arm two are all in the range of greater than 60° and less than 180°. The arc-shaped arm one and the arc-shaped arm two are respectively installed in parallel and opposite directions on the upper and lower sides of the inner frame of the arc-shaped base frame, and the ends of the arc-shaped arm one and the arc-shaped arm two are cross-connected.

[0011] Preferably, the outer end faces of the fixing block 2 and fixing block 1 at the ends of the arc arm 1 and arc arm 2 are respectively provided with corresponding insertion holes 2 and insertion holes 1.

[0012] Compared with the prior art, this utility model provides a power engineering surveying device, which has the following beneficial effects:

[0013] 1. This power engineering survey equipment, through the splicing clamps connected end to end, clamps half-pipe one and half-pipe two in the semi-composite pipe. The two ends of the spring in the splicing clamp are pulled by the two ends of the two arc-shaped connecting pieces, so it will not expand outward. It can clamp half-pipe one and half-pipe two in the semi-composite pipe more stably, and will not separate due to the soil sample stuffed inside the semi-composite pipe, and will not affect the sealing and stability of the semi-composite pipe.

[0014] 2. This power engineering surveying equipment, through its rigid telescopic clamps that interlock at both ends, is not easily expanded or deformed by external forces. It can also more stably clamp half-pipe one and half-pipe two in the semi-composite pipe, preventing separation due to soil samples being inserted into the semi-composite pipe. This does not affect the sealing and stability of the semi-composite pipe. Furthermore, when the arc arms one and two are rotated in opposite directions and retracted into the arc-shaped bottom frame, the central angle corresponding to the rigid telescopic clamp is no greater than 180°. This ensures that the retracted rigid telescopic clamp can quickly snap into the annular groove on the outside of the semi-composite pipe, making installation faster and more convenient.
