DETAILED DESCRIPTION OF THE EMBODIMENTS
[0022] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.
[0023] Such as Figures 1 to 5As shown in the figure, the utility model provides a ranging device for power engineering survey, which includes a protective cylinder 1. A storage bin 6 is opened at the top of the protective cylinder 1. A rangefinder 2 is arranged inside the storage bin 6. A limiting ring 7 is fixedly sleeved at the top of the inner cavity of the storage bin 6. The lower end of the rangefinder 2 is movably sleeved inside the storage bin 6, and the upper end of the rangefinder 2 is movably sleeved inside the limiting ring 7. A control device 3 is arranged at the bottom of the inner cavity of the storage bin 6. The bottom of the rangefinder 2 is fixedly connected to the top of the control device 3. A number of uniformly distributed support frames 4 are connected to the side of the protective cylinder 1. The bottom of the support frame 4 extends below the protective cylinder 1 and is connected to a limiting component 5 located at the bottom of the protective cylinder 1. Due to the setting of the control device 3, it is convenient to store the rangefinder 2 under the cooperation of the storage bin 6 and the limiting ring 7, thereby achieving the effect of convenient use and storage, and avoiding damage to the rangefinder 2 caused by bumps or tipping during daily storage.
[0024] Among them, the control device 3 includes a limiting base 31 that is movably sleeved inside the storage bin 6 and fixedly connected to the bottom of the rangefinder 2. A lead screw 33 is slidably clamped at the bottom of the limiting base 31. The bottom of the lead screw 33 is connected to two sliding sleeves on the left and right. The bottoms of the two sliding sleeves are slidably clamped at the bottom of the inner cavity of the storage bin 6. The two sliding sleeves are internally threaded with the lead screw 33. Both ends of the lead screw 33 penetrate the sliding sleeves and the storage bin 6 and extend to the outside of the protective cylinder 1 and are fixedly connected to a first knob 34. Due to the setting of the two first knobs 34 on the left and right, it is convenient for the operator to operate with either free hand on the left or right during use, improving the convenience of operation.
[0025] Among them, the support frame 4 includes a limiting cylinder 41 integrally formed on the side of the protective cylinder 1. An expansion rod 42 is movably sleeved inside the limiting cylinder 41. The lower end of the expansion rod 42 penetrates the limiting cylinder 41 and extends below the protective cylinder 1 and is connected to the limiting component 5. A positioning cone 43 is fixedly connected to the bottom of the expansion rod 42.
[0026] Among them, the expansion rod 42 includes a plunger hermetically sleeved inside the limiting cylinder 41. The bottom of the plunger is connected to a hinge. The lower end of the hinge extends to the bottom of the limiting cylinder 41 and is connected to a first-stage rod. A second-stage rod is hermetically sleeved inside the first-stage rod. The bottom of the second-stage rod penetrates the first-stage rod and extends below the protective cylinder 1 and is connected to the limiting component 5. Due to the setting of the hinge, the expansion rod 42 extending to the bottom of the limiting cylinder 41 can swing outwards, thus forming a triangular support state.
[0027] Among them, the limiting component 5 includes an adjustment component 51 arranged directly below the protective cylinder 1. A number of uniformly distributed sliding sleeves 52 are arranged on the side of the adjustment component 51. The several sliding sleeves 52 correspond to the limiting cylinders 41 one by one. A sliding rod 53 is hermetically sleeved inside the sliding sleeve 52. One end of the sliding rod 53 close to the adjustment component 51 penetrates the sliding sleeve 52 and is fixedly connected to the adjustment component 51.
[0028] Among them, through holes are provided in the middle of the sliding rod 53 and the telescopic rod 42. One end of the sliding sleeve 52 away from the adjusting assembly 51 is hinged to the bottom of the secondary rod. The through hole in the sliding rod 53 is connected to the through hole in the telescopic rod 42 through the sliding sleeve 52 and a hose; due to the arrangement of the sliding sleeve 52 and the sliding rod 53, several telescopic rods 42 can be connected to keep them stable, so that air can flow under the cooperation of the through holes, and then the two can be telescopic, thus forming a triangular support state, so that the retraction can greatly reduce the overall volume of the device, thereby improving its stability during storage.
[0029] Among them, the adjusting assembly 51 includes a communicating vessel 511 fixedly connected between several sliding rods 53. A communicating cavity 512 and a second through hole 514 communicating with its top are provided inside the communicating vessel 511. Several first through holes 513 are evenly distributed on the side surface of the communicating vessel 511. The several first through holes 513 correspond to the sliding sleeves 52 one by one. The communicating cavity 512 is connected to the sliding rod 53 and the sliding sleeve 52 through the first through holes 513; due to the arrangement of the adjusting assembly 51, the limiting cylinder 41 and the telescopic rod 42 can be telescopic under the cooperation of the sliding sleeve 52 and the adjusting assembly 51. At the same time, the adjusting assembly 51 and the sliding sleeve 52 can also be independently telescopic, and the telescopic of the two parts can be fixed, so as to achieve the effects of storage and support fixation;
[0030] A plug 515 is threadedly sleeved on the top of the communicating vessel 511 at the top of the second through hole 514. The outer diameter of the plug 515 is larger than the inner diameter of the second through hole 514. The bottom of the plug 515 is hermetically attached to the top of the second through hole 514. The top of the plug 515 extends above the communicating vessel 511 and is fixedly connected with a second knob 516.
[0031] The working principle and usage process of the present utility model:
[0032] Rotate the second knob 516 to make the bottom of the plug 515 away from the second through hole 514, then the upper end of the second through hole 514 can be connected to the outside. At this time, pull up the protective cylinder 1, and under the action of gravity, the telescopic rod 42 and the limiting assembly 5 as a whole will move downward relatively, that is, the telescopic rod 42 will extend. When the primary rod slides out of the limiting cylinder 41, the primary rod and the secondary rod as a whole can swing outward under the cooperation of the hinge, and pull the sliding sleeve 52 to slide along the outer surface of the adjusting assembly 51. When the protective cylinder 1 reaches an appropriate height and the telescopic rod 42 swings to an appropriate angle, rotate the second knob 516 in the reverse direction to make the bottom of the plug 515 hermetically attached to the top of the second through hole 514. At this time, the second through hole 514 can be blocked, so that external air cannot enter the sliding sleeve 52, the sliding rod 53, the limiting cylinder 41 and the telescopic rod 42, and at the same time, it cannot be discharged, so as to fix the states of the telescopic rod 42, the limiting cylinder 41, the primary sliding sleeve 52 and the adjusting assembly 51;
[0033] Rotating either the left or right first knob 34 can cause the lead screw 33 to rotate. Due to the rotation of the lead screw 33, the left and right ends of the lower end of the telescopic frame 32 can be driven to approach each other under the limitation of the protective cylinder 1, thereby causing the telescopic frame 32 to extend. Due to the extension of the telescopic frame 32, its upper end can push the limit base 31 to slowly rise inside the storage bin 6, and with the cooperation of the limit ring 7, the upper end of the rangefinder 2 can extend above the protective cylinder 1 for easy operation.
