DETAILED DESCRIPTION

[0046] In order to make the purpose, technical scheme and advantages of the utility model more clear, the technical scheme of the utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor belong to the scope of the utility model.

[0047] Embodiment:

[0048] As Figures 1-10 shown, the control point device for measurement provided by the embodiment includes control stake 100, illumination mechanism 200, barrel 300 and barrel cover 400, wherein:

[0049] The control pile 100 can be a steel bar or a vertical pole, which is embedded in the ground with its top end above the ground, and its top surface is a spherical surface, and a cross 110 is arranged on the spherical surface. It should be noted that the cross 110 can be engraved on the spherical surface or protruded on the spherical surface. Before embedding the control pile 100, a base hole is first drilled in the ground, and then the middle and lower sections of the control pile 100 are inserted into the base hole and the concrete is poured in the base hole to fix the control pile 100 in the base hole.

[0050] The lighting mechanism 200 is detachably mounted on the control pile 100, and is used to provide illumination for the cross 110 at the top end of the control pile 100. It is easy to understand that the lighting mechanism 200 can emit light, and the emitted light illuminates the top end of the control pile 100 and the cross 110 at the top end.

[0051] The cylinder body 300 is a stainless steel structure, the top end of the cylinder body 300 penetrates to form a cylinder opening, a first through hole is formed at the center of the cylinder bottom of the cylinder body 300, the control pile 100 is inserted into the first through hole, the top end of the control pile 100 and the lighting mechanism 200 are located inside the cylinder body 300, and the cylinder cover 400 is detachably connected to the cylinder body 300, and the cylinder cover 400 covers the cylinder opening of the cylinder body 300. The cylinder cover 400 is also a stainless steel structural member.

[0052] In use, first, the control stake 100 is passed through the first through hole, then the control stake 100 is buried in the ground, so that the barrel 300 is placed on the ground, at this time, the cross 110 at the top end of the control stake 100 is located in the barrel 300, then the lighting mechanism 200 is installed on the control stake 100, so that the lighting mechanism 200 is also located in the barrel 300, finally, the barrel cover 400 is covered on the barrel opening of the barrel 300, at this time, the barrel 300 and the barrel cover 400 constitute a protective cover, the cross 110 at the top end of the control stake 100 and the lighting mechanism 200 are located inside the protective cover, so that the control stake 100 and the lighting mechanism 200 are protected by the protective cover, avoiding the control stake 100 being buried by silt, and effectively preventing the top end of the control stake 100 from being in contact with water, thereby reducing the probability of the control stake 100 rusting, and the protective cover composed of the barrel 300 and the barrel cover 400 can also buffer and block the impact of the control stake 100 from the outside. When using a total station to measure, the total station is erected on the control point device by using a tripod, then the barrel cover 400 is removed, so that the cross 110 at the top end of the control stake 100 is exposed, if it is in a tunnel or a dark environment, then the lighting mechanism 200 is used to emit light, so as to illuminate the cross 110 at the top end of the control stake 100, then the staff positions the total station according to the cross 110 at the top end of the control stake 100, so as to quickly and accurately realize the centering work of the total station. The control point device does not need an additional staff to hold a flashlight to illuminate the cross 110 at the top end of the control stake 100, so the control point device is more convenient to use. Moreover, after surveying is completed, the lighting mechanism 200, the barrel 300 and the barrel cover 400 can be removed from the control stake 100, so as to be recycled and reused, thereby reducing costs.

[0053] It is noted that the method of using the cross 110 at the top end of the control stake 100 as a reference datum for centering by the total station is prior art, so it will not be described in detail here. In addition, the protective cover composed of the barrel 300 and the barrel cover 400 can also be a transparent structure as a whole, for example, a protective cover made of tempered glass. In this case, the lighting mechanism 200 is controlled by wireless control to turn on and off. When used in the dark, the lighting mechanism 200 is remotely turned on by using a remote controller. Since the protective cover is transparent, the cross 110 at the top end of the control stake 100 can be seen through the protective cover without removing the protective cover. Furthermore, when in a lighted position, the lighting mechanism 200 can not be started.

[0054] Optionally, the cylinder cover 400 comprises a cover plate 410 and a convex tube 420, the cover plate 410 is a plate body capable of covering the cylinder mouth of the cylinder body 300, the cover plate 410 can be a steel plate, the convex tube 420 is integrally formed on the bottom surface of the cylinder body 300, and the convex tube 420 is matched with the cylinder mouth of the cylinder body 300. In use, the convex tube 420 is inserted into the cylinder mouth of the cylinder body 300, and the cover plate 410 is lapped on the top end of the cylinder body 300, so that the cylinder cover 400 is detachably connected to the cylinder body 300, and the cover plate 410 covers the cylinder mouth of the cylinder body 300 from above. When it is necessary to remove the cylinder cover 400, the cylinder cover 400 is pulled out of the cylinder body 300. Of course, the convex tube 420 can also be connected to the cylinder mouth of the cylinder body 300 in a screwing manner. In addition, the cylinder cover 400 can also be a cover hinged to the top end edge of the cylinder body 300.

[0055] More preferably, the convex tube 420 is sleeved with a first sealing ring 500, and the first sealing ring 500 is arranged between the cover plate 410 and the top end of the cylinder body 300, so that rainwater cannot enter the inside of the cylinder body 300 from the position where the cylinder cover 400 contacts the cylinder body 300, and the waterproof effect of the control point device is enhanced.

[0056] In order to lift the cylinder cover 400 in use, in the embodiment, a pull ring 430 is installed on the top surface of the cover plate 410 of the cylinder cover 400, and when it is necessary to lift the cylinder cover 400, the worker can exert a pulling force on the pull ring 430, so that the operation is more simple and convenient. Moreover, a recess 411 is formed on the top surface of the cylinder cover 400, and when the pull ring 430 is not needed, the pull ring 430 is embedded in the recess 411, so that the overall structure is more compact.

[0057] In order to achieve better waterproof effect, in the embodiment, a second sealing ring 600 is installed between the control pile 100 and the hole wall of the first through hole, and by means of the second sealing ring 600, water cannot enter the cylinder body 300 from the position where the control pile 100 contacts the cylinder bottom of the cylinder body 300.

[0058] An optional embodiment of the embodiment is as follows: the lighting mechanism 200 comprises a mounting seat 210, a lighting lamp and a battery 230, wherein:

It is easy to understand that the switch 250 controls the lighting lamp to be powered on or powered off. The battery 230 is a component for powering the lighting lamp, and since the battery 230 only needs to power the lighting lamp, the battery 230 can be a conventional storage battery 230, such as a No. 5 battery 230 or a No. 7 battery 230. The switch 250 can be a button switch 250 or a wireless switch 250. If the protective cover is an integral structure made of tempered glass, the switch 250 is a wireless switch 250. If the protective cover is a structure composed of the barrel 300 and the barrel cover 400, the switch 250 is a button switch 250.

[0060] Optionally, the mounting base 210 comprises a bottom plate 211 and a surrounding ring 212, wherein:

[0061] The bottom plate 211 is a steel plate, a second through hole is formed at the center position of the bottom plate 211, and the control post 100 is inserted and mounted in the second through hole to achieve detachable connection between the mounting base and the control post 100. The surrounding ring 212 is a stainless steel ring, which is welded and fixed or integrally formed on the top surface of the bottom plate 211, and surrounds the second through hole. The switch 250 and the battery 230 are both mounted on the bottom plate 211 and located within the surrounding ring 212, and the lighting lamp is mounted on the inner wall of the surrounding ring 212. In this way, the lighting mechanism 200 can be conveniently disassembled and assembled on the control post 100 for recycling and reuse.

[0062] More preferably, a bracket 120 is also fixed on the control post 100, the bracket 120 is a steel frame, which is welded and fixed on the outer wall of the middle part of the control post 100 and located inside the barrel 300, and the bottom plate 211 of the mounting base 210 is lapped on the bracket 120 and fixed by adhesion. With the bracket 120, the mounting base 210 of the lighting mechanism 200 is lifted away from the barrel bottom of the barrel 300, so that even if a small amount of water is deposited in the barrel 300, the probability of water entering the inside of the lighting mechanism 200 is also lower because the lighting mechanism 200 is lifted away from the barrel bottom of the barrel 300.

[0063] In order to further avoid water in the barrel 300 from entering the lighting mechanism 200, a third sealing ring 700 is installed between the control post 100 and the hole wall of the second through hole on the bottom plate 211 in this embodiment.

[0064] Optionally, the illuminating lamp in the embodiment is a lamp strip 220 arranged on the inner wall of the enclosure 212 along the circumference of the enclosure 212, so that the cross 110 at the top of the control pile 100 can be better illuminated.
