Description

Technical Field

[0001] This utility model relates to the technical field of waterproof structures for underwater topographic surveying instruments, and in particular to a waterproof structure for underwater topographic surveying instruments. Background Technology

[0002] Underwater topographic surveying instruments, also known as underwater depth sounders or side-scan sonars, are precision devices designed specifically for detecting and mapping underwater topography. They are mainly used in oceanographic research, waterway surveys, underwater archaeology, resource exploration, and environmental protection. They can accurately acquire seabed topographic information and create detailed seabed maps. Due to the complexity of the underwater environment and the influence of the humid environment, protecting the surveying instruments from water corrosion and damage is crucial. Currently, waterproof structures are often used to protect the key internal components of underwater topographic surveying instruments from water.

[0003] Staff often find that the commonly used waterproof structure for underwater topographic surveying instruments involves setting up a shell on the outside of the instrument. The shell is usually fitted onto the instrument, and then the cover is fixed to the shell with screws to cover the machine and ensure airtightness. Since underwater topographic surveying instruments are mostly used outdoors, tools are needed to connect or remove the screws each time they are used, which increases the complexity of operation. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a waterproof structure for underwater topographic surveying instruments.

[0006] The effect achieved by the above components is as follows: by placing the cover on the instrument body and snapping the connecting block into the connecting groove, the cover and the cover can be quickly connected together. The transparent plate is made of a special acoustic transparent material, such as polycarbonate or certain polymer materials, which can allow sound waves to pass through while ensuring transparency, preventing interference with the operation of the instrument body. This avoids the increased cumbersomeness of operation caused by having to use tools to connect or remove screws each time it is used.

[0007] Preferably, a fixing block is fixedly connected to each side of the cover, a sliding rod is slidably inserted on the fixing block, a locking block is fixedly connected to one end of the sliding rod, and a locking groove is opened on each side of the cover.

[0009] Preferably, a first spring is sleeved on the slide rod, one end of the first spring is fixedly connected to the slide rod, and the other end of the first spring is fixedly connected to the fixing block.

[0010] The effect achieved by the above components is as follows: during the process of the connecting block being inserted into the connecting groove, the two sides of the cover will push the inclined surface of the block, causing the slide rod to slide, so that the first spring is gradually stretched. Therefore, when the block comes into contact with the groove, the block will be inserted into the groove under the action of the spring rebound force of the first spring, making the operation more convenient.

[0011] Preferably, a plurality of airbags are fixedly connected to the inner wall of the connecting groove, and the plurality of airbags are interconnected.

[0012] The effect achieved by the above components is that after the cover and the cover are connected, the airbag squeezes the connecting block, which can further improve the stability of the connection and improve the sealing of the connection.

[0013] Preferably, the cover is provided with a sealing structure, which mainly consists of a sealing strip, and the sealing strip is fixedly connected to the cover.

[0014] The effect achieved by the above components is that when the cover and the cover are connected, the sealing strip will be squeezed to improve the sealing of the connection and prevent water from entering.

[0015] Preferably, the sealing strip has a cavity, and a plurality of telescopic columns are fixedly connected in the cavity.

[0016] The effect achieved by the above components is that the telescopic column will retract when the sealing strip is squeezed.

[0017] Preferably, a second spring is sleeved on the telescopic column, and the two ends of the second spring are respectively fixedly connected to the inner walls of the two sides of the cavity.

[0018] The effect achieved by the above components is that the retraction of the telescopic column will cause the second spring to retract, and the rebound force of the second spring will act on the sealing strip, so that the sealing strip is tightly attached to the connection between the cover and the cover, thereby further improving the sealing performance of the connection.

[0019] Preferably, an air nozzle is fixedly connected to the cover, the air nozzle is connected to the air bag, and a plug is provided on the air nozzle.

[0020] The effect achieved by the above components is that the airbag can be deflated through the air nozzle after the plug is opened, and the airbag can also be inflated through the air nozzle, thereby improving the service life of the airbag.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this utility model, by setting a connecting structure, the cover is put on the instrument body and the connecting block is snapped into the connecting groove, so that the cover and the cover can be quickly connected together. The transparent plate is a specially made acoustic transparent material, such as polycarbonate or certain polymer materials, which can allow sound waves to pass through while ensuring transparency, preventing interference with the operation of the instrument body. This avoids the situation that the operation is more cumbersome because tools are needed to connect or disassemble screws every time they are used. Attached Figure Description

Detailed Implementation

[0027] Example 1, as Figure 1 As shown, a waterproof structure for an underwater topographic surveying instrument includes an instrument body 1 and a cover 2, with a cover 3 provided on the instrument body 1 and the cover 2.

[0028] Reference Figure 1 , Figure 2 and Figure 4The cover 2 is provided with a connecting structure 4, which mainly consists of connecting blocks 41. The connecting blocks 41 are fixedly connected to the cover 2. The cover 3 has a connecting groove 42, and a transparent plate 47 is fixedly connected to the cover 3. By placing the cover 2 on the instrument body 1 and inserting the connecting blocks 41 into the connecting groove 42, the cover 2 and the cover 3 can be quickly connected together. The transparent plate 47 is made of a special acoustic transparent material, such as polycarbonate or certain polymer materials, which can allow sound waves to pass through while ensuring transparency, preventing interference with the operation of the instrument body 1. This avoids the increased cumbersome operation caused by having to use tools to connect or remove screws each time it is used. Fixing blocks 43 are fixedly connected to both sides of the cover 2. A sliding rod 44 is slidably inserted into the fixing block 43. A locking block 45 is fixedly connected to one end of the sliding rod 44. Locking grooves 46 are opened on both sides of the cover 3. The sliding rod 44 can drive the locking block 45 into the locking groove 46, which can limit the cover 3 and make the connection more stable. A first spring 48 is sleeved on the sliding rod 44. One end of the first spring 48 is fixedly connected to the sliding rod 44, and the other end of the first spring 48 is fixedly connected to the fixing block 43. During the process of the connecting block 41 being inserted into the connecting groove 42, the two sides of the cover 3 will push the inclined surface of the locking block 45, causing the sliding rod 44 to slide, so that the first spring 48 is gradually stretched. Therefore, when the locking block 45 contacts the locking groove 46, the locking block 45 will be inserted into the locking groove 46 under the action of the rebound force of the first spring 48, making the operation more convenient. Several airbags 49 are fixedly connected to the inner wall of the connecting groove 42. The airbags 49 are interconnected. After the cover 2 and the cover 3 are connected, the airbags 49 squeeze the connecting block 41, which can further improve the stability of the connection and improve the sealing of the connection.

[0029] Reference Figure 2 and Figure 3 The cover 3 is provided with a sealing structure 5, which mainly consists of a sealing strip 51. The sealing strip 51 is fixedly connected to the cover 3. When the cover 2 is connected to the cover 3, the sealing strip 51 is squeezed to improve the sealing of the connection and prevent water ingress. A cavity 52 is opened in the sealing strip 51, and several telescopic columns 53 are fixedly connected in the cavity 52. ​​When the sealing strip 51 is squeezed, the telescopic columns 53 will retract. A second spring 54 is sleeved on the telescopic column 53, and the two ends of the second spring 54 are fixedly connected to the two sides of the cavity 52 respectively. On the wall, the retraction of the telescopic column 53 will cause the second spring 54 to retract. Therefore, the rebound force of the second spring 54 will act on the sealing strip 51, making the sealing strip 51 tightly adhere to the connection between the cover 2 and the cover 3, thereby further improving the sealing performance of the connection. An air nozzle 55 is fixedly connected to the cover 3. The air nozzle 55 is connected to the airbag 49. A plug 56 is provided on the air nozzle 55. By opening the plug 56, the airbag 49 can be deflated through the air nozzle 55. Similarly, the airbag 49 can be inflated through the air nozzle 55 to improve the service life of the airbag 49.

[0030] Working principle: The cover 2 is placed on the instrument body 1, and the connecting block 41 is inserted into the connecting groove 42, which quickly connects the cover 2 and the cover 3 together. The transparent plate 47 is made of a special acoustic transparent material, such as polycarbonate or certain polymer materials, which can allow sound waves to pass through while ensuring transparency, preventing interference with the operation of the instrument body 1. This avoids the increased cumbersome operation caused by having to use tools to connect or remove screws every time it is used. The sliding rod 44 can drive the locking block 45 to be inserted into the slot 46, which can limit the cover 3 and make the connection more stable. During the process of the connecting block 41 being inserted into the connecting groove 42, the two sides of the cover 3 will push the inclined surface of the locking block 45, causing the sliding rod 44 to slide, so that the first spring 48 is gradually stretched. Therefore, when the locking block 45 contacts the slot 46, the locking block 45... Under the rebound force of the first spring 48, it will be inserted into the slot 46, making operation more convenient. After the cover 2 and the cover 3 are connected, the airbag 49 squeezes the connecting block 41, which can further improve the stability of the connection and improve the sealing of the connection. When the cover 2 and the cover 3 are connected, the sealing strip 51 will be squeezed to improve the sealing of the connection and prevent water from entering. When the sealing strip 51 is squeezed, the telescopic column 53 will retract. The retraction of the telescopic column 53 will drive the second spring 54 to retract. Therefore, the rebound force of the second spring 54 will act on the sealing strip 51, so that the sealing strip 51 is tightly attached to the connection between the cover 2 and the cover 3, thereby further improving the sealing of the connection. Open the plug 56, and the airbag 49 can be deflated through the air nozzle 55. Similarly, the airbag 49 can be inflated through the air nozzle 55 to improve the service life of the airbag 49.
