Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intertidal zone surveying equipment, in particular to a telescopic measuring pole for intertidal zone surveying. BACKGROUND

[0002] The intertidal zone is a transitional area between land and sea, referring to the coastal zone between the highest and lowest tide levels during the spring tide period. It is submerged by seawater during high tide and exposed during low tide. It is formed due to the periodic tidal fluctuations caused by the gravitational effects of the moon and the sun, exhibiting significant daily variation characteristics. This region includes three sub-zones: high tide zone, middle tide zone, and low tide zone, and is an ecologically sensitive area with frequent wave action and active nutrient exchange, featuring high biodiversity.

[0003] As a treasure trove of marine resources, the intertidal zone hosts important ecosystems such as salt marshes and benthic communities. Surveying its topographic changes can monitor dynamic processes such as coastal erosion and silt deposition, providing data support for mangrove restoration and biological habitat protection. The intertidal zone is a critical construction area for offshore wind power and cross-sea bridges. Accurate surveying of topographic elevation and bottom characteristics (such as silt layer thickness) can optimize engineering site selection and avoid geological risks. Meanwhile, surveying data are used to establish tidal models to predict the threat of storm surges and sea level rise to the coastal zone.

[0004] In the prior art, intertidal zone surveying is usually carried out using a surveying vehicle, but for deep water areas, a surveying ball is also needed for surveying operations. During the surveying process, the jolting of the surveying vehicle during travel can severely affect the surveying accuracy, and the surveying capability for deep water areas of the intertidal zone is extremely limited. SUMMARY

[0007] The drone and the accessory box are detachably installed, an installation bracket is further welded and fixed to the bottom of the telescopic rod, a filter bin is welded and fixed to the bottom of the installation bracket, a floating bin is arranged below the filter bin, and a sampling bin is arranged below the floating bin.

[0008] As a preferred embodiment of the above-mentioned technical solution, a heat dissipation opening is further arranged on the accessory box.

[0009] As the preferred technical scheme of the above, the upper end face of the filter bin is provided with an inner pressure adjusting electromagnetic valve, a balance electromagnetic valve and a flushing electromagnetic valve, and the filter bin is communicated with the inner pressure adjusting electromagnetic valve, the balance electromagnetic valve and the flushing electromagnetic valve;

[0010] The inner pressure adjusting electromagnetic valve is also communicated with one end of a hose, and the other end of the hose is communicated with a blowing and sucking dual-purpose air pump.

[0011] The flushing electromagnetic valve is also communicated with one end of a copper pipe, and the other end of the copper pipe is communicated with a spray head.

[0012] The inner cavity bottom of the filter bin is provided with a filter screen, and the lower part of the filter bin is welded with a floating bin; the inner cavity of the floating bin is provided with a piston plate, the piston plate slides on the inner wall of the floating bin, and the lower end face of the piston plate is welded with a sampling rod; the bottom of the floating bin is provided with a connecting flange, the bottom of the connecting flange is provided with a sampling bin, and the floating bin is detachably connected with the sampling bin through the connecting flange; a sampling channel is arranged in the inner cavity of the sampling bin, and the bottom of the sampling rod extends out of the sampling channel and is welded with a sampling plate.

[0013] As the preferred technical scheme of the above, the mounting bracket is welded with a reinforcing rib.

[0014] As the preferred technical scheme of the above, the outer edge of the piston plate is welded with a sealing plate.

[0015] As the preferred technical scheme of the above, the top of the sampling channel is welded with a material guide plate.

[0016] As the preferred technical scheme of the above, the accessory box is bolted with an external plate, and the external plate is also welded with a steering disc.

[0017] As the preferred technical scheme of the above, the bottom of the external plate is welded with a mounting rod, a mounting sleeve is slidably sleeved on the mounting rod, the top end of the telescopic rod is welded on the mounting sleeve, the left and right ends of the mounting sleeve are welded with baffle plates, and a buffer spring is also sleeved on the mounting rod.

[0018] The present application provides a telescopic measuring pole for intertidal zone surveying, which has the following advantages:

[0019] 1. The accessory box is provided with a heat dissipation opening, which can ventilate and dissipate heat for the satellite positioning assembly, the inertial navigation assembly, the encoder and the single-beam depth measurement assembly arranged in the accessory box, and also can reduce signal blocking.

[0020] 2. During surveying, the balance solenoid valve is in the open state, while the internal pressure regulating solenoid valve and flushing solenoid valve are in the closed state. At this time, water enters the filter chamber, filling the filter chamber and the floating chamber above the piston plate. The filter chamber and the floating chamber above the piston plate have the same pressure as the seawater. However, the floating chamber below the piston plate is connected to the sampling chamber, and the sampling chamber is connected to the outside through the sampling channel. Therefore, the entire filter chamber, floating chamber, and sampling chamber will not act as a float and will not affect the normal surveying of the surveying sphere.

[0021] 3. During sampling, when the sampling rod is pushed downwards, the blow-suction air pump is in blowing mode, the flushing solenoid valve is closed, and the internal pressure regulating solenoid valve and the balancing solenoid valve are in alternating intermittent switching mode. This allows the piston plate to be pushed downwards a short distance when the balancing solenoid valve is closed and the internal pressure regulating solenoid valve is open. Seawater is then injected through the balancing solenoid valve to balance the internal and external pressures, ultimately pushing the sampling plate out for sampling. After sampling, the blow-suction air pump switches to suction mode, and the sampling rod is raised using the same method. This allows the sample on the sampling plate to enter the sampling chamber through the sampling channel. Finally, the sampling rod is raised and lowered repeatedly in the sampling chamber using the same method, causing it to swing up and down within the chamber, shaking the sample from the sampling plate into the chamber, thus completing the sampling process. The removable sampling chamber facilitates easy removal and replacement after sampling.

[0022] 4. When the surveying ball gets entangled with seaweed or other plants on the seabed, this device can be used to free it. The method is as follows: First, raise the piston plate to the highest position by operating the sampling operation. Then, close the balance solenoid valve and the flushing solenoid valve, open the internal pressure regulating solenoid valve, set the blow-suction dual-purpose air pump to the blowing mode, and inflate the floating chamber until the piston plate is lowered to the lowest position. At this time, the internal space of the floating chamber can provide the maximum buoyancy in the seawater, which will drive the telescopic rod and the surveying ball to float up and complete the freeing.

[0023] 5. After the object is freed, the flushing solenoid valve can be opened again to spray and clean the dirt adhering to the outer surface of the surveying ball. Attached Figure Description

[0031] like Figures 1-4 As shown in this embodiment, a telescopic measuring rod for intertidal zone mapping includes a drone 1. The drone 1 has an accessory box 2 at its lower part. The accessory box 2 contains a satellite positioning component 4, an inertial navigation component 5, an encoder 6, and a single-beam depth sounding component 7. A telescopic rod 13 is located below the accessory box 2. A mapping ball 14 is connected to the bottom of the telescopic rod 13. A counterweight 35 is provided on the mapping ball 14.

The bottom of the mounting bracket 15 is welded and fixed with a filter chamber 20. A floating chamber 22 is set below the filter chamber 20. A sampling chamber 27 is set below the floating chamber 22. The filter chamber 20 is used to filter seawater to prevent debris from entering the floating chamber 22 and causing wear on the precision seals inside the floating chamber 22, which would affect its airtightness and cause the floating function to fail. The sampling chamber 27 can sample the bottom soil biomass of the tidal zone during the surveying process of the surveying ball 14.

[0033] In specific implementation, the accessory box 2 is also provided with a heat dissipation vent 3, which can provide ventilation and heat dissipation for the satellite positioning component 4, inertial navigation component 5, encoder 6 and single beam depth sounding component 7 installed in the accessory box 2, and can also reduce signal obstruction.

[0042] In the embodiment, when sampling, the sampling rod 25 is pushed downward, the blowing and sucking dual-purpose air pump 36 is in the blowing mode, the flushing electromagnetic valve 19 is in the closed state, the inner pressure regulating electromagnetic valve 17 and the balance electromagnetic valve 18 are in the alternating intermittent open state, so that when the balance electromagnetic valve 18 is closed and the inner pressure regulating electromagnetic valve 17 is opened, the piston plate 23 can be pushed downward by a small distance, then the inner pressure regulating electromagnetic valve 17 is closed and the balance electromagnetic valve 18 is opened to fill seawater from the balance electromagnetic valve 18, balance the inner and outer pressure, and finally the sampling plate 28 is pushed out of the sampling; after sampling, the blowing and sucking dual-purpose air pump 36 is changed to the sucking mode, and the sampling rod 25 is lifted by the same method, so that the sample on the sampling plate 28 enters the sampling bin 27 through the sampling channel 30; finally, the sampling rod 25 is repeatedly lifted and lowered in the sampling bin 27 by the above method, the sampling rod 25 is swung up and down in the sampling bin 27, the sample on the sampling plate 28 is shaken into the sampling bin 27, and the sampling is completed.

[0044] In the embodiment, when the surveying ball 14 is entangled with the plants such as seaweed on the seabed, the device needs to be used to get rid of the entanglement, the method for getting rid of the entanglement is that the piston plate 23 is lifted to the highest position by the operation during sampling, then the balance electromagnetic valve 18 and the flushing electromagnetic valve 19 are closed, the inner pressure regulating electromagnetic valve 17 is opened, the blowing and sucking dual-purpose air pump 36 is set to the blowing mode, air is filled into the floating bin 22, and the piston plate 23 is lowered to the lowest position, at this time, the space in the floating bin 22 can provide the maximum buoyancy in seawater, drive the telescopic rod 13 and the surveying ball 14 to float up and get rid of the entanglement, after getting rid of the entanglement, the flushing electromagnetic valve 19 can be opened to spray and clean the dirt attached to the outer surface of the surveying ball 14.

[0045] It should be noted that the upper and lower end faces of the floating bin 22 are provided with limit plates to avoid the piston plate 23 from falling off during the sliding process on the inner wall of the floating bin 22.

The sample on the sampling plate 28 falls into the sampling bin 27 and finally falls into the storage bin 31 formed by the bottom of the sampling bin 27 and the lower end face of the guide plate 29, which has a sealing effect. After the sampling is completed, the sampling bin 27 moves in the seawater, and the storage bin 31 can protect the sample to remain intact in the storage bin 31.
