Description

Technical Field

[0001] The utility model relates to the technical field of total station prisms, in particular to a prism used for nighttime measurement of a total station. Background Art

[0002] In surveying work, the use of total stations is not limited to basic surveying tasks such as coordinate setting out. It is also widely used in infrastructure construction such as bridges and tunnels, and deformation monitoring of large buildings and structures. The primary condition for the use of total stations is that there must be line of sight between observation points. Its measurement accuracy and efficiency are not only related to the operator's proficiency and work experience, but also closely related to the observation environment conditions. Especially when the total station is used to monitor the settlement of the arch and the displacement of the crown beam of a newly built tunnel or to monitor the inclination of large buildings or structures in foggy weather, due to the low lighting intensity of the tunnel and the low visibility in foggy weather, the total station spends more time looking for the target prism and aiming the prism, and it is difficult to aim at the center of the prism. The communication of measurement information and the advancement of measurement progress are greatly affected by the electromagnetic wave signals in the tunnel, which makes the measurement difficult and the measurement accuracy difficult to guarantee. It limits the distance measurement range of the total station and reduces the measurement efficiency. At present, when measuring under low visibility conditions, a surveying operator must illuminate the total station prism to complete the measurement, which is more labor-intensive and time-consuming for the total station to find the target, which increases the difficulty of measurement. Therefore, there is an urgent need for a new type of total station prism to facilitate use in conditions of low visibility, thereby reducing the difficulty of measurement for staff.

[0022] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0023] The following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] The utility model is a prism used for nighttime measurement of total station, please refer to Figure 1-4, including a main body 1 and a prism plate 2, the main body 1 is arranged on the prism plate 2, an arrow icon 3 is arranged on the prism plate 2, and the arrow icon 3 points to the main body 1, and a first light source 4 is arranged on the outer arm of the main body 1, and the first light source 4 is used to illuminate the prism plate 2. During use, the first light source 4 illuminates the arrow icon 3 on the prism plate 2, so that the inspection personnel can more easily observe the prism in the case of low visibility, which greatly reduces the measurement difficulty of the staff. Secondly, it is well known that light directly shines on the human eye or the surface of an object, and forms a strong light after reflection or scattering. Stimulation, that is, glare, glare may interfere with our visual experience, reduce visual comfort and visual quality. Therefore, in this embodiment, the first light-emitting body 4 is also provided with a first shading plate 5. The first shading plate 5 is arranged on the side of the first light-emitting body 4 away from the prism plate 2. The first end of the first shading plate 5 is arranged on the first light-emitting body 4, and the second end of the first shading plate 5 extends away from the main body 1. The first shading plate 5 blocks the light emitted by the first light-emitting body 4, so that the light emitted by the first light-emitting body 4 only illuminates the prism plate 2, thereby avoiding the generation of glare, which greatly improves the user experience of the detection personnel.

[0025] In this embodiment, the side of the first shading plate 5 close to the prism plate 2 is a mirror structure, so that the light emitted by the first light-emitting body to the first shading plate 5 can be reflected onto the prism plate 2, thereby increasing the brightness of the prism plate 2, making it easier to observe the prism, and further reducing the measurement difficulty of the staff.

[0026] More preferably, in the present embodiment, the second end of the first shading plate 5 gradually tilts toward the prism plate 2 in the direction away from the main body 1, so that the light energy emitted by the first light source is more concentratedly irradiated on the prism plate 2, further increasing the brightness of the prism plate 2, making it easier to observe the prism, thereby reducing the measurement difficulty for the staff.

[0027] In this embodiment, the arrow icon 3 is made of reflective material, so that when the first light source illuminates the prism plate 2, the arrow icon 3 on the prism plate 2 is more conspicuous, thereby enabling the inspector to observe the main body 1 more conveniently.

[0028] In this embodiment, one or more arrow icons 3 are provided on the prism plate 2, and when multiple arrow icons 3 are provided on the prism plate 2, the arrow icons 3 are arranged around the main body 1, so that the detection personnel can more conveniently determine the position of the main body 1.

[0029] In this embodiment, the main body 1 includes a shell 6, a glass prism 7 and a second illuminant 8. A housing cavity 9 is provided in the shell 6. The glass prism 7 is arranged in the housing cavity 9. A cross mark 10 for assisting the total station in aiming is also provided on the glass prism 7. As is known to all, when the operator observes through the telescope of the total station, they will see a light image reflected by the prism, and this image will contain the cross mark 10 on the prism. The operator needs to adjust the position and angle of the total station so that the cross mark 10 in the telescope coincides with the actual target point, thereby completing the aiming and positioning process. Therefore, in order for the operator to clearly observe the cross mark 10 at night or in other conditions with low visibility, in this embodiment, a second illuminant 8 is arranged in the housing cavity 9, and the cross mark 10 is illuminated by the second illuminant 8, so that the operator can clearly observe the cross mark 10 at night or in other conditions with low visibility.

[0030] In this embodiment, a second shading plate 11 is also included, a cross mark 10 is arranged at one end of the glass prism 7 located at the opening of the shell 6, a second light-emitting body 8 is arranged at the opening of the shell 6, and a second shading plate 11 is arranged on a side of the second light-emitting body 8 away from the glass prism 7 to prevent the second light-emitting body from generating glare, thereby affecting the user experience of the total station operator.

[0031] In this embodiment, a power supply device and a control device are also included, and the power supply device, the first light-emitting body and the second light-emitting body are all electrically connected to the control device.

[0032] The above disclosures are only several specific embodiments of the present invention, but the present invention is not limited thereto, and any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
