Description

Technical Field

[0001] The utility model relates to the technical field of water area surveying and mapping, in particular to a water area surveying and mapping device. Background Art

[0002] In the actual surveying process, it is sometimes necessary to survey areas containing water areas, and it is necessary to collect underwater data through surveying and mapping devices. An ultrasonic depth sounder, also known as an echo sounder, is an instrument that uses the principle of sound wave reflection to measure water depth. It is mainly used for surveying and mapping of water areas. A rapid water depth measuring instrument for water area surveying and mapping proposed in accordance with a Chinese invention patent (application number: 202210148750.8) includes a fixed seat; an adsorption component arranged on the inner wall of the fixed seat for fixing to the ship wall and a control for controlling the adsorption component. However, the patent uses an electromagnet to fix the surveying and mapping device to the hull, but when the electromagnet is out of power, the surveying and mapping device needs to be manually held, which is more laborious and cannot effectively fix the surveying and mapping device.

[0003] The publication (announcement) number is CN219223736U, which discloses a water surveying and mapping device, belonging to the field of water surveying and mapping technology, including a support seat and a connecting plate installed on the support seat, a threaded rod is rotatably installed on the connecting plate, a first support plate is rotatably installed on one end of the threaded rod, a second connecting frame is installed on the first support plate, a sliding cavity that cooperates with the second connecting frame is opened on the support seat, a connecting rod is installed on the top of the support seat, and a third plug-in block is installed on the bottom of the connecting rod. The utility model can facilitate the installation of the connecting rod by setting a third plug-in block to engage with the third slot, can facilitate the installation of the connecting rod and the second connecting frame on the support seat, can limit the connecting rod by setting a second plug-in block to engage with the second slot, can fix the moving connecting rod by setting a first plug-in block to engage with the first slot, can drive the first support plate to move by rotating the threaded rod, and the first support plate is connected to the inner wall of the ship.

[0004] Although the above scheme effectively fixes the surveying and mapping device, the surveying and mapping instrument is still on the hull as a whole after being fixedly assembled on the equipment. It is difficult to mobilize the surveying and mapping instrument alone to the water surface for accurate depth measurement. The fixation and sealing protection of the surveying and mapping instrument requires multiple points to be operated one by one. The equipment fixing and sealing operation is cumbersome and inefficient. For this reason, we propose a surveying and mapping device for water areas. Utility Model Content

[0005] The main purpose of the utility model is to provide a surveying and mapping device for water areas, which solves the problem that the surveying and mapping instrument is difficult to be independently mobilized to the water surface for accurate depth measurement through the provided calling unit.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions: A surveying and mapping device for water areas, comprising a support unit and a depth sounder, further comprising: a calling unit and a limiting and sealing unit arranged between the support unit and the depth sounder;

[0007] The calling unit includes a bracket, a transverse lead screw, a support block, an extension sleeve and a sealing cover plate. The bracket is in a "U" shape with a hollow interior and is located directly above the support unit. The transverse lead screw is movably arranged on the inner wall of one end of the bracket. There are two support blocks in total. One of the support blocks is threadedly connected to the transverse lead screw. One end of the extension sleeve is connected to the side surface of the support block. The sealing cover plate is fixedly arranged at the other end of the extension sleeve that extends out of the bracket. A first turntable is fixedly arranged at the end of the transverse lead screw that extends out of the bracket;

[0008] The limiting and sealing unit includes a longitudinal lead screw, guide blocks, a limiting plate and a storage box. Two strip-shaped mounting grooves are symmetrically opened on the side of the sealing cover plate facing the concave surface of the bracket. The longitudinal lead screw is movably arranged on one of the strip-shaped mounting grooves. There are four guide blocks in total and they are equally divided into two groups. One group of guide blocks respectively cooperate with the positive and negative two sections of threads symmetrically arranged on the longitudinal lead screw. The limiting plate is in an "L" shape. One limiting plate is fixedly arranged at the end faces of every two guide blocks located on the same vertical central horizontal plane. The storage box is fixedly arranged on the concave surface of the bracket, and the limiting plate extends into the storage box movably. A second turntable is fixedly arranged at the end of the longitudinal lead screw that extends out of the sealing cover plate;

[0009] Preferably, the calling unit further includes a transverse guide rod. The transverse guide rod is fixedly arranged on the inner wall of the other end of the bracket and movably penetrates through the other support block.

[0010] Preferably, the extension sleeve and the support block are arranged in one-to-one correspondence.

[0011] Preferably, the limiting and sealing unit further includes a longitudinal guide rod. The longitudinal guide rod is fixedly arranged on the other strip-shaped mounting groove and movably penetrates through the other group of guide blocks.

[0012] Preferably, the depth sounder is placed on the concave surfaces of the two limiting plates and is located inside the storage box.

[0013] Preferably, the support unit includes a support arm and a counterweight base plate. The support arm is in an "L" shape and is fixedly arranged at the corner of the bottom surface of the bracket. An installation hole is opened on the concave surface at the bottom end of the support arm.

[0015] 1. In the utility model, by setting a calling unit, the supporting unit can fix and support the bracket inside the hull. After the depth sounder is assembled to the limit plate, the transverse screw rod can be controlled to rotate forward and backward on the bracket by holding the first turntable. One of the supporting blocks threadedly connected to the transverse screw rod can be subjected to force to drive the extension sleeve to translate on the bracket to adjust the exposed area. The closed cover plate can then drive the limit plate and the depth sounder to expand and translate to above the water surface outside the hull. The other supporting block can slide and translate on the transverse guide rod to cooperate with the extension sleeve and the closed cover plate to mobilize and provide auxiliary support for them. After the reverse operation, the depth sounder can be adjusted back. The device enables the depth sounder to be flexibly and easily mobilized alone to the water surface for accurate depth measurement.
