Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy projects, and particularly to a marine hanging basket type fixing device for a sounding probe head. Background Art

[0002] Currently, ultrasonic detectors are widely used in the fields of water depth and underwater topography measurement in rivers, lakes, reservoirs, waterways, and coastal areas. The sounding instrument places the ultrasonic transducer probe head at a certain position below the water surface, and uses the fixed sound speed of ultrasonic waves in water and the time from ultrasonic wave emission to reception to estimate the water depth at the detection point. However, in actual measurement, there is a lack of a universal fixing device for the sounding probe head fixing device. Usually, it is necessary to rely on workers to hold it by hand, paste it on the ship wall with tape, or tie it to the ship column with a rope. Since it is difficult to ensure that the water depth of the probe head remains unchanged when held by hand, especially for operators engaged in long-term continuous water operations, relying on manual fixation not only wastes human resources but also consumes physical strength; relying on simple pasting methods such as tape and tying methods are also difficult to achieve good fixing effects when the hull is smooth or there are no attachments. Coupled with the influence of environmental factors such as wind and waves on the water surface, it directly affects the accuracy of detection data. Therefore, a marine hanging basket type fixing device for a sounding probe head is needed. Summary of the Invention

The top of the clamping plate 19 is fixedly connected with an inclined guiding plate 101. The bottom of the telescopic rod 16 is provided with a receiving groove 17 arranged along its length direction. A piston rod 18 of an L-shaped structure slidably sleeved with the air pipe 14 is installed inside the receiving groove 17. The inner side wall of the top of the receiving groove 17 and the top of the piston rod 18 are clamped by a tooth and a tooth groove. The top of the piston rod 18 is fixedly connected with a first spring fixedly connected to the inner side wall of the top of the telescopic pipe 15.

[0029] In addition, the detection and connection assembly 3 includes a U-shaped connection seat 31 fixedly connected to the adjacent substrate 41. A first rotating rod is movably sleeved at the opening of the connection seat 31. A first upper arm is fixedly sleeved on the first rotating rod. The other end of the first upper arm is fixedly connected with a rotating seat 33. A second rotating rod is movably sleeved on the rotating seat 33. A second lower arm is fixedly sleeved on the second rotating rod. The other end of the second lower arm is fixedly connected with a probe fixing sleeve 35. An ultrasonic probe 36 is clamped by the probe fixing sleeve 35.

[0030] In addition, one end of the first rotating rod extending out of the connecting seat 32 is threadedly sleeved with a first fastening nut that abuts against the connecting seat 32, and one end of the second rotating rod extending out of the rotating seat 33 is threadedly sleeved with a second fastening nut that abuts against the rotating seat 33.

[0031] Furthermore, a clamping groove is formed at the top of the first sleeve 54 along its length direction, and clamping teeth that are clamped with the clamping groove are fixedly connected to the bottom of the pressing disc 58.

[0032] Preferably, a second spring fixedly connected to the inner side wall of the installation box 11 is fixedly connected to the top of one end of the telescopic rod 16 extending into the telescopic tube 15, a third spring fixedly connected to the bottom inner wall of the installation box 11 is fixedly connected to the bottom of the pressing plate 13, one side of the opening of the installation box 11 is hinged with a cover plate 102, a pressing plate of an annular structure is fixedly connected to the bottom of the cover plate 102, a fourth spring fixedly connected to the substrate 41 is fixedly connected to one end of the extension tube 46 away from the suction cup 44, and an operation window penetrates through the cover plate 102.

[0033] Working principle: When placing the control box 12 in the installation box 11, open the cover plate 102 located on the installation box 11, and then place the control box 12 into the installation box 11 from the top opening. After that, place the control box 12 downward. First, it presses against the guiding plate 101 until the control box 12 contacts the clamping plate 19. At this time, push the control box 12 to move along the length and width directions of the installation box 11 to adjust the position of the control box 12 inside the installation box 11. At this time, the clamping plate 19 and the telescopic rod 16 move along with the control box 12, and the telescopic rod 16 slides along the length direction of the telescopic tube 15. When adjusting the position of the control box 12, continue to press the control box 12 downward. At this time, the control box 12 first contacts the pressing plate 13, and then the pressing plate 13 moves downward along with the control box 12. When the pressing plate 13 moves downward, the gas at the bottom of the pressing plate 13 moves upward along the air pipe 14 and then pushes the piston rod 18 upward. At this time, the piston rod 18 is clamped with the receiving groove 17 on the telescopic rod 16, so as to clamp and limit the telescopic rod 16. At this time, the pressing plate 13 clamps and fixes the control box 12. After that, cover the cover plate 102 downward on the top of the installation box 11. When covering, stabilize the control box 12 downward from the operation window, and then the pressing plate fixes the top of the control box 12.

[0034] When the control box 12 is placed inside the installation box 11, it needs to be fixed to the ship. During the fixing process, two sets of housing 42 are placed downward from both sides of the ship's edge until the top of the ship's edge contacts the top of the support plate 61. Then, the two sets of substrates 41 are pushed towards each other until the housing 42 of the substrate 41 contacts the inner and outer sides of the ship's edge. At the same time, the suction cups on the housing 42 contact the inner and outer side walls of the ship's edge. During the fixing process, the adjusting rod 57 is rotated, and under the action of the thread, the moving block 56 moves upward. At this time, the two sets of sleeves 54 move upward, and the two sets of guide columns 53 also move upward until the pressing disc 58 on the adjusting rod 57 is clamped with the top of the sleeve 54. At this time, the pressing disc 58 locks the sleeve 54, and the guide column 53, the sleeve 54, the hand-held tube 59, and the holding rod 510 are relatively stationary and do not move, so that the two sets of substrates 41 are in a clamped state;

[0035] When the guide column 53 and the sleeve 54 move upward, the two sets of pressing plates 52 both move upward, and the gas inside the housing 42 is evacuated along the through hole 47 to the guide tube 51. The pressure of the housing 42 decreases, and the suction cups 44 adsorb and fix the inner and outer side walls of the ship's edge, thereby improving the clamping and fixing force with the ship. After that, the detection connection assembly 3 is used to adjust the position of the ultrasonic probe 36 for detection operations. This design can first be suitable for the clamping and fixing operations of control boxes for different types of ultrasonic probes, facilitate operations on the control box, and can be conveniently and quickly installed on the ship. When installed on the ship, it is fixed to the ship by adsorption, improving the clamping and fixing strength, avoiding falling off and loosening during the shaking of the ship during navigation, ensuring the safety of the detection equipment, and facilitating the installation and detection operations of the detection personnel.
