Description

Technical Field

[0001] The invention belongs to the technical field of water depth measurement, and in particular relates to a field measurement device. Background Art

[0002] Water depth measurement is a basic method of underwater topography measurement. It is mainly used to determine the underwater topography and the depth below the water surface. The purpose is to provide the channel depth for ships and determine the location, depth and nature of navigation obstacles. The tools used for water depth measurement are basically sounding rods and echo sounders. Echo sounders are expensive and highly accurate, but they are relatively complicated to use. They are mainly used for water depth measurement in large rivers. Water depth measurement in inland tributaries and small rivers is mainly based on sounding rods.

[0003] Since the length of the sounding rod is limited, the prior art uses a rope to measure the depth, mainly by fastening a counterweight at one end of the rope, then throwing the counterweight into the water, driving the rope down through the counterweight until it falls to the bottom of the water, and then measuring the depth of the water through the rope. However, this measurement method is only applicable to stagnant water bodies. In flowing water bodies, the impact of the water flow will cause the rope in the water body to be curved, resulting in inaccurate depth data, which brings unnecessary trouble to users.

[0004] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art. Summary of the invention

[0009] The support driving mechanism is installed on one side of the outer protection tube sleeve, and the support driving mechanism includes a support protection box, a fixing frame is fixed on the support protection box, a telescopic support frame is inserted in the fixing frame, and a limiting column is fixed on the telescopic support frame;

[0010] The limit alignment mechanism is installed on the measuring end rod and the split measuring rod, and the limit alignment mechanism is used to align the outer protective tube sleeve and the split measuring rod to facilitate vertical downward movement; wherein, the limit alignment mechanism includes a pair of limit levers, and the pair of limit levers are installed on the measuring end rod and the split measuring rod, and an alignment linkage column is slidably arranged in the limit lever, and a socket matching the alignment linkage column is chiseled at one end of the limit lever away from the alignment linkage column.

[0011] In one or more embodiments of the present invention, the outer protective tube sleeve is threadedly connected with a plurality of push screws for driving the clamping arc plate to move, so that the measuring end rod or the split measuring rod can be clamped by the plurality of clamping arc plates, which facilitates the installation and disassembly of the split measuring rod. One end of the push screw is rotatably connected with the clamping arc plate for fixing the measuring end rod or the split measuring rod, so that the measuring end rod or the split measuring rod is not easy to be lifted or moved, thereby ensuring stability.

[0012] A support bearing is fixedly connected between the push screw and the clamping arc plate, which is used to fix one end of the push screw so that the push screw will not fall off and the rotation of the push screw will not be affected by the clamping arc plate, so that the push screw can tighten the clamping arc plate against the measuring end rod or the outer wall of the split measuring rod;

[0013] A rubber protective pad is fixed on the clamping arc plate to protect the measuring end rod and the split measuring rod, so that the measuring end rod and the split measuring rod will not be damaged during the process of tightening the measuring end rod or splitting the measuring rod, and it can also increase the friction effect, thereby improving the fixing effect of the measuring end rod or the split measuring rod.

[0014] In one or more embodiments of the present invention, a limit strip is fixedly installed on the outer protective tube sleeve and is used to be inserted between a pair of limit levers, so that the upper measuring end rod or the split measuring rod is not easy to change direction when it descends or rises, thereby realizing the role of limit guide.

[0015] In one or more embodiments of the present invention, a threaded hole is drilled at one end of the measuring end rod and the detached measuring rod, and a connecting column matching the threaded hole is installed at one end of the detached measuring rod to increase the measuring length, so that the measuring end rod can be connected to multiple detached measuring rods, thereby facilitating the depth measurement of the water body, and can be disassembled when not in use for easy transportation and storage.

[0016] In one or more embodiments of the present invention, an extrusion support block is installed at one end of the buffer support column inserted in the trigger cavity, which is used to support the buffer support column and the silt-breaking cone so that the buffer support column and the silt-breaking cone will not fall off, and it also has the function of an extrusion buffer spring. A buffer spring is fixedly connected between the extrusion support block and the measuring end rod, which is used to push the extrusion support block, so that the silt-breaking cone is not easy to retract into the trigger cavity, and then when the silt-breaking cone is inserted into the sludge in the water body, it will not directly retract. Because of the pushing of the buffer spring, the silt-breaking cone will only retract when it is inserted into the bottom of the water, thereby improving the accuracy of the measuring depth and will not be affected by the silt.

[0017] In one or more embodiments of the present invention, a sliding trigger block and a fixed trigger sleeve are arranged between the extrusion support block and the measuring end rod, the sliding trigger block is fixed on the measuring end rod, and the fixed trigger sleeve is fixed on the extrusion support block. When the fixed trigger sleeve is inserted into the sliding trigger block, it indicates that the silt-breaking cone has been inserted into the bottom of the water. At this time, the driving motor stops working, so that the silt-breaking cone will not continue to be inserted downward, and it is also convenient for the staff to calculate the depth of the water body.

[0018] In one or more embodiments of the present invention, a driving motor and an intelligent control box are installed in the support protection box, the driving motor is used to drive the rotation of the transmission support shaft, so as to provide power for driving the measuring end rod and the split measuring rod to move up and down, and the intelligent control box is electrically connected with the sliding trigger block, the fixed trigger sleeve and the driving motor, so that when the fixed trigger sleeve is inserted into the sliding trigger block, the driving motor can be controlled to be turned off;

[0019] The output end of the driving motor is fixedly connected with a transmission support shaft for supporting one of the driving gears and the interlocking gear to play a supporting and transmission role. A secondary support shaft is provided on one side of the transmission support shaft for supporting the other driving gear and the interlocking gear. A fixed bearing is fixedly connected between one end of the transmission support shaft and the secondary support shaft and the support protection box to fix the transmission support shaft and the secondary support shaft so that the transmission support shaft and the secondary support shaft will not tilt or shake, and the rotation stability of the transmission support shaft and the secondary support shaft is guaranteed.

[0020] In one or more embodiments of the present invention, driving gears and linkage gears are installed on the transmission support shaft and the auxiliary support shaft. A pair of the driving gears are used to drive the lifting and lowering movement of the measuring end rod and the split measuring rod. A pair of the linkage gears are used to link the transmission support shaft and the auxiliary support shaft, so that a pair of driving gears can rotate at the same time and in opposite directions. A pair of the driving gears are meshed with the lifting drive racks, and a pair of the linkage gears are meshed with each other.

[0021] In one or more embodiments of the present invention, a lifting groove is opened in the fixed frame to provide space for the lifting and lowering movement of the telescopic support frame. A supporting base plate is arranged in the lifting groove to support the telescopic support frame to prevent the telescopic support frame from falling off. The supporting base plate is fixedly connected to one end of the telescopic support frame. A plurality of fixed springs are fixedly connected between the supporting base plate and the fixed frame to pull the telescopic support frame back to its original position for facilitating subsequent use.

[0022] In one or more embodiments of the present invention, a support spring is fixedly connected between the alignment linkage column and the limit lever, which is used to pull the alignment linkage column back to its original position, so as to facilitate the removal of the split measuring rod after measurement for storage.

[0023] A plurality of limit grooves are drilled at one end of the alignment linkage column for the engagement of the limit protrusion, so that the alignment linkage column is fixed in the socket on the other limit gear rod. A plurality of limit protrusions matching the limit grooves are fixed on the side wall of the socket, so as to fix the alignment linkage column so that the alignment linkage column will not retract, thereby ensuring that the measuring end rod and the split measuring rod or a pair of split measuring rods can be aligned with each other, facilitating lifting and lowering movement.

DETAILED DESCRIPTION

[0039] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0040] like Figure 1-Figure 11 As shown, a field measurement device in an embodiment of the present invention includes: a fixed base 1, a detachable measurement mechanism 2, a support driving mechanism 3 and a limit alignment mechanism 4.

[0041] like Figure 1-Figure 3 As shown, the detachable measuring mechanism 2 is installed on the fixed pedestal 1, and the detachable measuring mechanism 2 includes an outer protective tube sleeve 201, which is used to provide the direction and space for measurement. A measuring end rod 202 is inserted into the outer protective tube sleeve 201, which is used to cooperate with multiple detachable measuring rods 211 to measure the depth of the water body. The multiple detachable measuring rods 211 can be disassembled and installed, so that the device does not take up too much space when not in use, and can measure water bodies of any depth. The upper part of the outer protective tube sleeve 201 is threadedly connected with a detachable measuring rod 211.

[0042] like Figure 1-Figure 5 As shown, a plurality of evenly distributed lifting drive racks 203 are installed on the measuring end rod 202 and the split measuring rod 211, which are used to conveniently drive the measuring end rod 202 and the split measuring rod 211 to move up and down. A trigger cavity is excavated at the lower end of the measuring end rod 202 to provide space for the insertion and separation of the sliding trigger block 215 and the fixed trigger sleeve 216. A buffer support column 204 is inserted into the trigger cavity to support the silt breaking cone 205 and drive the silt breaking cone 205 to move. The end of the buffer support column 204 arranged outside the trigger cavity is fixedly connected to the silt breaking cone 205, which is used to facilitate breaking the silt, reduce the influence of the silt on the measurement data, and thus improve the accuracy of the measurement.

[0043] like Figure 7-Figure 8 As shown, the outer protective tube sleeve 201 is threadedly connected with a plurality of push screws 206, which are used to drive the clamping arc plate 207 to move, so that the measuring end rod 202 or the split measuring rod 211 can be clamped by the plurality of clamping arc plates 207, which facilitates the installation and removal of the split measuring rod 211. One end of the push screw 206 is rotatably connected with the clamping arc plate 207, which is used to fix the measuring end rod 202 or the split measuring rod 211, so that the measuring end rod 202 or the split measuring rod 211 is not easy to move up and down, thereby ensuring stability.

[0044] Among them, a support bearing 208 is fixedly connected between the pushing screw 206 and the clamping arc plate 207, which is used to fix one end of the pushing screw 206 so that the pushing screw 206 will not fall off and the rotation of the pushing screw 206 will not be affected by the clamping arc plate 207, thereby enabling the pushing screw 206 to tighten the clamping arc plate 207 against the outer wall of the measuring end rod 202 or the disassembled measuring rod 211.

[0045] In addition, a rubber protective pad 209 is fixed on the clamping arc plate 207 to protect the measuring end rod 202 and the split measuring rod 211, so that the measuring end rod 202 and the split measuring rod 211 will not be damaged during the process of tightening the measuring end rod 202 or splitting the measuring rod 211, and the friction effect can be increased, thereby improving the fixing effect of the measuring end rod 202 or the split measuring rod 211. A limit strip 210 is fixedly installed on the outer protective tube sleeve 201, which is used to be inserted between a pair of limit stop bars 401, so that the upper measuring end rod 202 or the split measuring rod 211 is not easy to change direction when descending or ascending, thereby realizing the role of limit guide.

[0046] like Figure 1-Figure 4 As shown, threaded holes are drilled at one end of the measuring end rod 202 and the detached measuring rod 211, and a connecting column 212 matching the threaded hole is installed at one end of the detached measuring rod 211 for increasing the measuring length so that the measuring end rod 202 can be connected to multiple detached measuring rods 211, thereby facilitating the depth measurement of the water body, and can be disassembled when not in use for easy transportation and storage.

[0047] like Figure 1-Figure 5 As shown, an end of the buffer support column 204 inserted in the trigger cavity is installed with an extrusion support block 213, which is used to support the buffer support column 204 and the silt-breaking cone 205, so that the buffer support column 204 and the silt-breaking cone 205 will not fall off, and also has the function of squeezing the buffer spring 214. A buffer spring 214 is fixedly connected between the extrusion support block 213 and the measuring end rod 202, which is used to push the extrusion support block 213, so that the silt-breaking cone 205 is not easy to retract into the trigger cavity, and then when the silt-breaking cone 205 is inserted into the sludge in the water body, it will not retract directly. Because of the push of the buffer spring 214, the silt-breaking cone 205 will only retract when it is inserted into the bottom of the water, thereby improving the accuracy of the measurement depth and will not be affected by the silt.

[0048] Specifically, a sliding trigger block 215 and a fixed trigger sleeve 216 are arranged between the extrusion support block 213 and the measuring end rod 202. The sliding trigger block 215 is fixed on the measuring end rod 202, and the fixed trigger sleeve 216 is fixed on the extrusion support block 213. When the fixed trigger sleeve 216 is inserted into the sliding trigger block 215, it indicates that the silt-breaking cone 205 has been inserted into the bottom of the water. At this time, the driving motor 305 stops working, so that the silt-breaking cone 205 will not continue to be inserted downward, and it is also convenient for the staff to calculate the depth of the water body.

[0049] like Figure 1-Figure 3 As shown, the support driving mechanism 3 is installed on one side of the outer protection tube sleeve 201, and the support driving mechanism 3 includes a support protection box 301, which is used to play a supporting role and improve the stability of the device. A fixed frame 302 is fixed on the support protection box 301, which is used to support the telescopic support frame 303 so that the telescopic support frame 303 will not fall off. The telescopic support frame 303 is inserted in the fixed frame 302, which is used to support the limit column 304.

[0050] Specifically, a limiting column 304 is fixed on the telescopic support frame 303, which is used to play a role of limiting alignment when the split measuring rod 211 is installed, so that the split measuring rod 211 will not fall off during the tightening process.

[0051] like Figure 1-Figure 6 As shown, a driving motor 305 and an intelligent control box are installed in the support protection box 301. The driving motor 305 is used to drive the rotation of the transmission support shaft 306, thereby providing power for driving the measurement end rod 202 and the split measurement rod 211 to move up and down. The intelligent control box is electrically connected to the sliding trigger block 215, the fixed trigger sleeve 216 and the driving motor 305, so that when the fixed trigger sleeve 216 is inserted into the sliding trigger block 215, the driving motor 305 can be controlled to be turned off.

[0052] like Figure 6 As shown, the output end of the driving motor 305 is fixedly connected with a transmission support shaft 306, which is used to support one of the driving gears 308 and the linkage gear 309, and plays a supporting and transmission role. A secondary support shaft 307 is provided on one side of the transmission support shaft 306, which is used to support another driving gear 308 and the linkage gear 309. A fixed bearing 310 is fixedly connected between one end of the transmission support shaft 306 and the secondary support shaft 307 and the support protection box 301, which is used to fix the transmission support shaft 306 and the secondary support shaft 307, so that the transmission support shaft 306 and the secondary support shaft 307 will not be skewed or shaken, and the rotation stability of the transmission support shaft 306 and the secondary support shaft 307 is guaranteed.

[0053] Specifically, a driving gear 308 and a linkage gear 309 are installed on the transmission support shaft 306 and the auxiliary support shaft 307. A pair of driving gears 308 are used to drive the lifting and lowering movement of the measuring end rod 202 and the split measuring rod 211. A pair of linkage gears 309 are used to link the transmission support shaft 306 and the auxiliary support shaft 307, so that the pair of driving gears 308 can rotate at the same time and in opposite directions. The pair of driving gears 308 are meshed with the lifting drive rack 203, and the pair of linkage gears 309 are meshed with each other.

[0054] like Figure 1-Figure 9 As shown, a lifting groove 311 is opened in the fixed frame 302 to provide space for the lifting and moving of the telescopic support frame 303. A supporting bottom plate 312 is arranged in the lifting groove 311 to support the telescopic support frame 303 to prevent the telescopic support frame 303 from falling off. The supporting bottom plate 312 is fixedly connected to one end of the telescopic support frame 303. A plurality of fixing springs 313 are fixedly connected between the supporting bottom plate 312 and the fixed frame 302 to pull the telescopic support frame 303 back to its original position for subsequent use.

[0055] like Figure 1-Figure 11 As shown, the limit alignment mechanism 4 is installed on the measuring end rod 202 and the split measuring rod 211. The limit alignment mechanism 4 is used to align the outer protective tube sleeve 201 and the split measuring rod 211 to facilitate vertical downward movement. The limit alignment mechanism 4 includes a pair of limit levers 401, which are used to align the outer protective tube sleeve 201 and the split measuring rod 211 or a pair of split measuring rods 211. The pair of limit levers 401 are installed on the measuring end rod 202 and the split measuring rod 211. An alignment linkage column 402 is slidably arranged in the limit lever 401 to play a linkage role. A socket matching the alignment linkage column 402 is drilled at one end of the limit lever 401 away from the alignment linkage column 402.

[0056] like Figure 1-Figure 11 As shown, a support spring 404 is fixedly connected between the alignment linkage column 402 and the limit lever 401, which is used to pull the alignment linkage column 402 back to its original position, so as to facilitate the removal of the split measuring rod 211 after measurement for storage. A paddle 403 is installed on the alignment linkage column 402 to facilitate the sliding of the alignment linkage column 402 for easy operation.

[0057] like Figure 10-11As shown, one end of the alignment linkage column 402 is provided with a plurality of limiting grooves for the locking of the limiting protrusion 405, so that the alignment linkage column 402 is fixed in the insertion hole on the other limiting lever 401. A plurality of limiting protrusions 405 matching the limiting grooves are fixed on the side wall of the insertion hole, so as to fix the alignment linkage column 402 so that the alignment linkage column 402 will not retract, thereby ensuring that the measuring end rod 202 and the split measuring rod 211 or a pair of split measuring rods 211 can be aligned with each other, so as to facilitate lifting and lowering.

[0058] When in use, the staff first starts the driving motor 305 to raise the measuring end rod 202 to a certain distance, then takes out a section of the detached measuring rod 211, aligns the threaded hole at the upper end of the detached measuring rod 211 with the limit column 304 and inserts it, then pushes the telescopic support frame 303 to rise until the connecting column 212 connected to the lower end of the detached measuring rod 211 can be inserted into the threaded hole on the measuring end rod 202. At this time, the telescopic support frame 303 will press on the detached measuring rod 211, so that the detached measuring rod 211 will have a downward thrust;

[0059] Then, the split measuring rod 211 is rotated so that the connecting column 212 can rotate in the threaded hole on the measuring end rod 202, so that the split measuring rod 211 and the measuring end rod 202 are threadedly connected and tightened to achieve the effect of fixed connection, and then the paddle 403 is pushed so that the paddle 403 drives the alignment linkage column 402 to move, so that the alignment linkage column 402 can be inserted into the jack in the upper limit lever 401, so that the split measuring rod 211 is aligned with the measuring end rod 202, and then the driving motor 305 is started again, so that the driving motor 305 drives the pair of driving gears 308 to rotate, and the measuring end rod 202 and the split measuring rod 211 are driven to descend through the pair of driving gears 308, so as to achieve the effect of downward insertion, and the split measuring rod 211 can be continuously added subsequently to achieve the effect of increasing the measuring distance;

[0060] When the silt-breaking cone 205 contacts the river bottom, it will first be inserted into the silt. However, due to the elastic effect of the buffer spring 214, the squeezing support block 213 is not easy to move upward, so that the silt-breaking cone 205 continues to be inserted downward. When the silt-breaking cone 205 contacts the river bottom mud, the squeezing support block 213 will move upward due to resistance, and then the fixed trigger sleeve 216 will be inserted into the sliding trigger block 215. At this time, the driving motor 305 will stop working, so that the sliding trigger block 215 will no longer move downward, and the accurate depth of the river water body can be measured.

[0061] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0062] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
