Description

Technical Field

[0001] The utility model belongs to the technical field of surveying beacon lights, in particular to a sea-crossing and river-crossing elevation surveying beacon light. Background Art

[0002] Cross-sea and cross-river elevation measurement beacon lights refer to marker lights used for measuring elevation at sea or in rivers. These beacon lights are usually set on the measurement line across the ocean or river to indicate the specific measurement location or provide a reference point. Such beacon lights can help surveyors accurately measure the surface elevation.

[0003] When the leveling route crosses the sea or river and the line of sight exceeds the line of sight length specified for leveling, observations must be made according to the cross-river leveling method. The longer the line of sight is, the smaller the image of the graticule on the level rod in the level telescope becomes. When the line of sight exceeds a certain length, the level cannot clearly aim at the distant level rod, or even cannot recognize and aim at the graticule on the rod. At this time, the usual practice is to appropriately enlarge the graticule lines of the level rod according to a certain proportion, make a special sighting plate for cross-river leveling and place it on the level rod, make a corresponding bracket and fix it in the sea or river, and then install it on the bracket for observation and aiming of the far shore level or theodolite.

[0004] When the existing spy boards are used, pollutants in the sea or river will adhere to the surface of the spy boards for various reasons. When observation is needed through the spy boards, they cannot be used and need to be manually cleaned before observation can be carried out, which greatly increases the workload of the staff and is inconvenient to use.

[0015] (III) Beneficial effects

[0016] The utility model provides a cross-sea and cross-river elevation measurement beacon light, which has the following beneficial effects:

[0017] 1. The cross-sea and cross-river elevation measurement beacon is used in conjunction with a cross wind plate, a reciprocating screw rod and a cleaning rod. When the wind drives the cross wind plate to rotate, it synchronously drives the driving rod and the reciprocating screw rod to rotate, so that the cleaning rod moves up and down on the surface of the reciprocating screw rod and cleans the pollutants on the surface of the target body through the brush on its surface, which reduces the cleaning work of the staff and improves the work efficiency of the staff.

[0018] 2. The cross-sea and cross-river elevation measurement beacon is used in conjunction with a heating plate, a compression cylinder and a piston rod. When an ice layer forms on the surface of the target body due to weather or other reasons, the staff will cause measurement errors due to light refraction when measuring. At this time, the heating plate is energized to increase the air temperature inside the heating cylinder. When the cleaning rod moves up and down, it drives the piston rod to move up and down inside the compression cylinder, compressing the high-temperature gas inside and discharging it from the strip exhaust groove. The high-temperature gas is used to melt the ice layer, thereby reducing the error during measurement. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] See also Figures 1 to 7 The utility model provides a cross-sea and cross-river elevation measurement beacon light; it includes a target body 1 and a base 2, the target body 1 is fixedly connected to the top of the base 2, the top of the base 2 is fixedly connected to a fixing frame 3, and a rotatable cross wind plate 4 and a reciprocating screw rod 5 are provided between the top plate and the bottom plate of the fixing frame 3.

[0029] A cleaning rod 6 for cleaning the sign-seeking body 1 is provided on the surface of the reciprocating screw rod 5, a driving rod 7 meshingly connected to the top of the reciprocating screw rod 5 is provided on the top of the cross wind plate 4, a driving assembly for driving the reciprocating screw rod 5 to rotate is provided on the top of the fixed frame 3, and a plurality of LED lights 8 are provided on the surface of the sign-seeking body 1.

[0030] Note: The distribution shape of the LED lights 8 is evenly and equidistantly arranged according to the pattern on the surface of the target body 1 to increase the accuracy of the measurement by the surveyor. The upper surface of the base 2 is provided with mounting holes to facilitate subsequent installation by bolts.

[0031] like Figure 3 As shown, the top of the cross wind plate 4 penetrates into the interior of the fixed frame 3, and the surface of its top is in the shape of a bevel gear, and is meshed with the driving rod 7 (both ends of which are provided with bevel gears). At this time, the other end of the driving rod 7 is meshed with the top of the reciprocating screw rod 5 (the top of which is in the shape of a bevel gear), and the bottom ends of the cross wind plate 4 and the reciprocating screw rod 5 are columnar (not shown in the figure) and are arranged inside the bottom plate of the fixed frame 3.

[0032] like Figure 1As shown, the fixing frame 3 is arranged in a C shape, which plays an important role in supporting the cross wind plate 4 and the reciprocating screw rod 5. The cleaning rod 6 is opposite to the shape of the fixing frame 3, and a plurality of brushes are provided on the surface of the bottom, which are attached to the side of the target body 1. When the wind drives the cross wind plate 4 to rotate, the cleaning rod 6 moves up and down on the surface of the reciprocating screw rod 5, and removes the dirt on the surface of the target body 1 through the brushes on its surface.

[0033] A support plate 9 is fixedly connected to the surface of the bottom end of the base 2, and a heating cylinder 10 is fixedly connected to the upper surface of the support plate 9 at one end along the first direction. The heating cylinder 10 includes a heating plate 11 on the inner bottom wall for heating the air, a compression cylinder 12 fixedly connected to the top for compressing the air and connected to the heating cylinder 10, and a piston rod 13 arranged inside the compression cylinder 12 and movable up and down, the top of the piston rod 13 passes through the inner top wall of the compression cylinder 12 and is fixedly connected to the surface of the cleaning rod 6.

[0034] like Figure 1 and Figure 2 As shown, the upper surface of the heating cylinder 10 is provided with an exhaust hole. When the piston rod 13 moves downward, the compression cylinder 12 is in a closed state, and the excess heat inside the heating cylinder 10 is discharged from the exhaust hole. Due to the cold outside temperature, the hot air flow will quickly lose when it enters the air flow chamber 15. Therefore, the piston rod 13 and the cleaning rod 6 are provided with an insulation layer (as shown in the attached figure). Figure 2 ), the purpose of such a setting is that when the heated air passes through the airflow cavity 15, the loss of hot air flow can be reduced, the power consumption of the heating plate 11 is reduced, and the melting efficiency of the ice layer on the surface of the target sign body 1 is improved.

[0035] A first one-way valve 31 is provided inside the bottom end of the compression cylinder 12, a second one-way valve 14 is provided inside the bottom end of the piston rod 13, an air flow chamber 15 is provided inside the cleaning rod 6 and the piston rod 13 and is connected to each other, and a strip exhaust groove 16 is provided on the upper surface of the bottom end of the cleaning rod 6 and is connected to the air flow chamber 15.

[0036] Note: The strip exhaust groove 16 provided on the upper surface of the cleaning rod 6 is inclined (at 30 degrees), and the exhaust gas is directed toward the side of the target body 1 (the measuring part).

[0037] The driving assembly includes a protective tube 17 fixedly connected to the upper surface of the top plate of the fixing frame 3, a driving motor 18 arranged on the top of the protective tube 17, a connecting rod 19 fixedly connected to the output end of the driving motor 18, and a gear rod 20 sleeved on the bottom end of the connecting rod 19 and meshingly connected to the driving rod 7. A return spring 21 is sleeved on the surface of the gear rod 20.

[0038] like Figure 3 As shown, when the drive assembly is in use;

[0039] When the staff needs to measure the target body 1, at this time, the cleaning rod 6 is in the middle part of the side of the target body 1 due to the cross wind plate 4, which will affect its measurement. At this time, the drive motor 18 is started to synchronously drive the connecting rod 19 and the gear rod 20 to rotate. When the connecting rod 19 rotates, the cross bar 22 is driven to rotate, and the auxiliary rod 23 is squeezed. The auxiliary rod 23 reciprocates left and right under the action of the compression spring 24, and the gas compressed by the auxiliary rod 23 enters the space of the gear rod 20 and the C point cavity. At this time, the gear rod 20 drives the reset spring 21 to slowly compress downward until its bottom end is meshed and connected with the drive rod 7. At this time, the cleaning rod 6 is driven to move upward or downward to the edge of the target body 1. At this time, the drive motor 18 is stopped and the measurement work starts;

[0040] When the bottom end of the gear rod 20 is meshed with the driving rod 7 to drive it to rotate, air will continue to be inflated into the cavity at point C. When the air pressure reaches a certain level, the pressure valve 30 inside the second exhaust chamber 27 opens to discharge excess gas.

[0041] Note: The pressure value of the pressure valve 30 is greater than the elastic force value of the return spring 21. When the return spring 21 is in an incompressible state, the pressure valve 30 is opened.

[0042] A cross bar 22 is fixedly connected to the surface of the connecting rod 19, an auxiliary rod 23 used in conjunction with the cross bar 22 is provided inside the protective tube 17, a compression spring 24 is fixedly connected to the end of the auxiliary rod 23 away from the cross bar 22, and an air intake chamber 25, a first exhaust chamber 26 and a second exhaust chamber 27 are provided inside the protective tube 17.

[0043] An air intake check valve 28 is provided inside the air intake chamber 25, an exhaust check valve 29 is provided inside the first exhaust chamber 26, a pressure valve 30 is provided inside the second exhaust chamber 27, a control module is provided on the upper surface of the support plate 9 close to the base 2, a battery is provided on the lower surface of the support plate 9 away from the end of the heating tube 10, a generator is provided on the top of the fixing frame 3, and its output end extends to the inside of the fixing frame 3 and is fixedly connected to the top of the cross wind plate 4, and the control module is connected to the battery and the generator through external wires.

[0044] When the cross wind plate 4 rotates, the mechanical energy generated by the generator on its top is converted into direct current through a current rectifier (not shown in the figure) to charge the battery (this is a known technology). The battery is equipped with a power-off protector, which automatically disconnects the circuit when it is fully charged to protect the battery.

[0045] Note: The above-mentioned battery, generator, heating plate 11, drive motor 18 and control module are all existing well-known technologies and are only cited here. The specific structure is not described in detail. The heating plate 11 and the LED lamp 8 are connected to the battery through external wiring and are controlled by the control module.

[0046] The electrical components mentioned in this article are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device for controlling a computer or the like.

[0047] When the equipment is in the initial state, the bottom of the gear rod 20 in the driving assembly is separated from the driving rod 7, the sighting plate body 1 is connected to the leveling rod through the base 2 at the bottom, and is fixed on a prepared bracket, which is located at the measuring position in the sea or river and is in a usable state.

[0048] In the utility model, the working steps of the device are as follows:

[0049] 1. When in use, when the cross wind plate 4 rotates, the bevel gear on its top is meshed with the bevel gear on one end of the driving rod 7. At this time, the driving rod 7 synchronously drives the reciprocating screw rod 5 to rotate, thereby driving the cleaning rod 6 to move up and down on the surface of the reciprocating screw rod 5. The brush on the bottom end of the cleaning rod 6 is used to clean the dirt on the surface of the target body 1 to avoid affecting the use during measurement;

[0050] 2. When it is rainy or snowy, ice will form on the surface of the main body 1 of the target. At this time, the battery energizes the heating plate 11, and the heating plate 11 increases the air temperature inside the heating cylinder 10. When the cleaning rod 6 moves upward, the first one-way valve 31 is in a conducting state, and the second one-way valve 14 is in a non-conducting state. The hot air inside the heating cylinder 10 enters the bottom of the piston rod 13 and the cavity at point b, and the gas in the cavity at point a is discharged from point d (as shown in the attached figure). Figure 2 ), when the cleaning rod 6 moves downward, the external gas enters the cavity above the piston rod 13 and at point a from point d, the first one-way valve 31 is in a non-conducting state, the second one-way valve 14 is in a conducting state, and the compressed hot gas enters the interior of the air flow cavity 15 and is discharged from the strip exhaust groove 16 on the bottom surface of the cleaning rod 6, which facilitates melting of the ice layer on the surface of the target body 1 and reduces the error during measurement;

[0051] 3. When it is necessary to measure the target body 1, the battery powers the LED lamp 8 to maintain the brightness of the side of the target body 1, which is convenient for measurement. When there is no wind, the cross wind plate 4 is in a stopped state. When there is wind, the cross wind plate 4 is in a rotating state. When the cleaning rod 6 is in the middle part of the side of the target body 1, refer to the above-mentioned process of when the drive assembly is used;

[0052] 4. Further description of the drive assembly; when the cross bar 22 rotates to the position where the auxiliary rod 23 is located, it is squeezed. At this time, the compression spring 24 moves to the right, and the intake check valve 28 is in a non-conducting state. The external gas enters the space where the auxiliary rod 23 is located from point e, and the exhaust check valve 29 is in a conducting state. The compressed gas enters the cavity at point c from the first exhaust chamber 26, so that the gear rod 20 drives the reset spring 21 to move downward. When the cross bar 22 is away from the auxiliary rod 23, the compression spring 24 drives the auxiliary rod 23 to move to the left, and the exhaust check valve 29 is in a non-conducting state, and the intake check valve 28 is in a conducting state. The external gas enters the cavity at point f, and the gas in the space where the auxiliary rod 23 is located is discharged from point e, and it reciprocates left and right until its bottom is engaged and connected with the drive rod 7, thereby facilitating the adjustment of the position of the cleaning rod 6.
