Description

Technical Field

[0001] The invention belongs to the technical field of measuring equipment, and in particular relates to an ice-breaking type measuring bracket. Background Art

[0002] In waterway, port and other construction projects, water measurement is generally involved. The measurement indicators include but are not limited to water depth, water flow velocity and water temperature. Water measurement is usually carried out by surveying ships. When sailing or parked, the measuring device installed on the construction ship will lower the measuring sensor / probe underwater to perform the measurement operation. If the water measurement process is arranged after the ice melts, there are usually the following problems: During the measurement process, the surveying ship controls the speed at 7-8 knots. If there are a lot of floating ice in the construction area, it will cause great damage to the measuring bracket. The floating ice will cause additional resistance to the measuring bracket. When the floating ice hits the measuring bracket, it causes the measuring sensor / probe to vibrate strongly, affecting the measurement accuracy. Even if the surveying ship performs the measurement operation when it is parked, when there is floating ice on the surface of the water flow, the aforementioned problems still exist.

[0003] Therefore, the survey vessel needs a stable survey support that can smoothly and effectively perform survey operations even when there is floating ice on the water surface. Summary of the invention

[0004] The purpose of the present invention is to provide an ice-breaking measuring bracket, which can smoothly and effectively perform measuring operations even when there is floating ice on the water surface, avoid the measuring bracket being damaged by the floating ice, and avoid excessive vibration that is detrimental to the measuring probe during the measuring process.

[0012] The advantages and positive effects of the present invention are:

[0013] The present invention provides an ice-breaking measuring bracket. Compared with the existing measuring bracket, the measuring bracket of the present invention has the function of electrically controlled lifting. When measuring, the lifting drive component is used to drive the measuring probe to descend and enter the water body. When not measuring, the lifting drive component is used to drive the measuring probe to rise above the water surface, so that the measuring probe is not immersed in the water body for a long time. In this way, during the non-measuring period and the high-speed navigation of the measuring ship, the measuring probe is protected by separating the measuring probe from the water body. At the same time, the measuring bracket and the measuring probe are allowed to be located outside the ship's side for a long time, avoiding frequent installation of the measuring bracket, and being able to perform measurement operations at any time and quickly, facilitating the measurement work and reducing the labor intensity of the measurement work.

[0014] The measuring bracket has an upper tube icebreaker cone plate installed at the front of the middle and lower part of the upper tube sleeve, and a lower tube icebreaker cone plate installed at the front of the lower tube sleeve. When the measuring ship is sailing, the front facades of the upper tube icebreaker cone plate and the lower tube icebreaker cone plate are ice-facing surfaces. The conical icebreaker cone plates can push the floating ice on the moving path to both sides, thereby producing an icebreaking effect, avoiding the measuring bracket from being damaged by the impact of the floating ice, and avoiding excessive vibration that is unfavorable to the measuring probe during the measurement process. Therefore, the icebreaker type measuring bracket can also smoothly and effectively perform measurement operations when there is floating ice on the water surface. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to further understand the content, features and effects of the present invention, the following embodiments are given to explain in detail.

[0022] See also Figure 1 , Figure 2 and Figure 3 The icebreaking measuring bracket of the present invention comprises a ship side base 1 installed on the outer side of the ship's side of the measuring ship, a lifting frame 2 is fixedly installed on the lower part of the outer end of the ship side base 1, the root of the ship side base 1 is fixedly connected to the outer side of the ship's side of the measuring ship, and the top of the lifting frame 2 is fixedly connected to the outer end of the ship side base 1.

[0023] An upper pipe sleeve 4 is provided below the lifting frame 2, an upper pipe ice-breaking cone plate 8 is fixedly installed in the front of the middle and lower part of the upper pipe sleeve 4, a lower pipe sleeve 9 is provided below the upper pipe sleeve 4, a lower pipe ice-breaking cone plate 11 is fixedly installed in front of the lower pipe sleeve 9, the upper end of the lower pipe sleeve 9 is fixedly connected to the lower end of the upper pipe sleeve 4 and is detachable, a support rod 12 is provided below the lower pipe sleeve 9, the upper end of the support rod 12 is fixedly connected to the lower end of the lower pipe sleeve 9 and is detachable, and a measuring probe 7 is installed at the lower end of the support rod 12.

[0024] When performing measurement operations, the measurement probe 7 is lowered into the water body, and when not performing measurement operations, the measurement probe 7 is raised above the water surface. The upper tube ice-breaking cone plate 8 is installed in front of the middle and lower part of the upper tube sleeve 4, and the lower tube ice-breaking cone plate 11 is installed in front of the lower tube sleeve 9 to produce an ice-breaking effect on the floating ice on the moving path, such as Figure 2 and Figure 3 As shown in the figure, since the front facades of the upper tube ice-breaking cone plate 8 and the lower tube ice-breaking cone plate 11, that is, the ice-facing surfaces, are conical in shape, the floating ice in front can be pushed to both sides, avoiding the floating ice from directly impacting the measuring bracket, avoiding the measuring bracket from being damaged by the floating ice, and at the same time avoiding excessive vibration to the measuring probe caused by the impact of the floating ice during the measurement process.

[0025] like Figure 2 and Figure 3 As shown in the figure, the upper tube ice-breaking cone plate 8 and the lower tube ice-breaking cone plate 11 both have an L-shaped cross-section and can be made by stamping or bending steel plates. The two side edges of the upper tube ice-breaking cone plate 8 are welded and fixed to the outer wall of the upper pipe sleeve 4. Similarly, the two side edges of the lower tube ice-breaking cone plate 11 are welded and fixed to the outer wall of the lower pipe sleeve 9. It is worth noting that the "ice-breaking" referred to in this patent is a figurative term, which does not refer to the active crushing of thicker ice layers, but the effect of pushing the floating ice formed by the melted ice layer to both sides, producing an effect similar to ice-breaking. In fact, if the ice layer on the water surface has not melted into floating ice, the construction conditions for water measurement are usually not met.

[0026] In this embodiment, flanges are provided at the lower end of the upper sleeve 4 and the upper end of the lower sleeve 9, and the two flanges are fixedly connected by bolts and a sealing gasket is provided between the two. A flange is provided at the lower end of the lower sleeve 9, and a top plate is provided at the upper end of the support rod 12, and the flange and the top plate are fixedly connected by bolts and a sealing gasket is provided between the two. The bolted connection method allows the upper sleeve 4 and the lower sleeve 9 to be disassembled, and the lower sleeve 9 and the support rod 12 to be disassembled. The purpose of providing sealing gaskets at adjacent connection positions is to prevent water from entering.

[0027] The cable of the measuring probe 7 extends upward along the inner cavity of the support rod 12, the lower sleeve 9 and the upper sleeve 4 in an inner wiring manner, and finally passes through the upper end opening of the upper sleeve 4, and then extends horizontally along the ship side base 1 to the deck of the measuring ship and is connected to the signal receiver. The inner wiring method can provide protection for the cable of the measuring probe 7, which can not only prevent the cable from being hit by floating ice during the navigation and movement of the measuring ship, but also prevent the cable from being corroded by the water body.

[0028] A lifting drive assembly 3 is also installed between the lifting frame 2 and the upper pipe sleeve 4. The lifting drive assembly 3 is used to controllably drive the upper pipe sleeve 4 and its accessories to move up and down. When performing measurement operations, the upper pipe sleeve 4 and its accessories are driven to descend and the measuring probe 7 enters the water body. Conversely, the upper pipe sleeve 4 and its accessories are driven to rise and the measuring probe 7 is lifted above the water surface.

[0029] See also Figure 4 , we can see that:

[0030] The lifting drive assembly 3 includes a center rod 3-3 fixed to the middle of the bottom of the lifting frame 2 and a plurality of outer sleeves 3-4 fixed to the bottom side of the lifting frame 2, and a stabilizing frame 3-7 is installed between the lower end of the center rod 3-3 and each outer sleeve 3-4.

[0031] A lead screw 3-6 is provided inside each outer sleeve 3-4 and a moving block 3-5 is provided on the lead screw 3-6. A strip groove 3-8 extending in the axial direction is provided on the outer wall of the outer sleeve 3-4 and the moving block 3-5 is located in the corresponding strip groove 3-8. A driving mechanism for driving the lead screws 3-6 to rotate synchronously is installed inside the hoisting frame 2. When the lead screws 3-6 rotate synchronously, the moving blocks 3-5 move synchronously up and down along the strip groove 3-8 in which they are located.

[0032] In this embodiment, the driving mechanism of the lifting drive assembly 3 includes a driving gear installed in the middle of the lifting frame 2 and a driven gear 3-2 installed at the upper end of each lead screw 3-6. Each driven gear 3-2 is meshed with the driving gear for transmission. A lifting drive motor 3-1 for driving the driving gear to rotate is also installed inside the lifting frame 2. The lifting drive motor 3-1 drives the driven gears 3-2 to rotate synchronously through the driving gear, so that each lead screw 3-6 moves forward or reverse synchronously, and each moving block 3-5 moves up and down synchronously.

[0033] In this embodiment, bearing seats 3-9 are provided at the upper and lower ends of the outer sleeve 3-4, the upper end of the screw 3-6 is fixedly connected to the inner ring of the bearing located in the upper bearing seat 3-9, and the lower end of the screw 3-6 is fixedly connected to the inner ring of the bearing located in the lower bearing seat 3-9. By providing two upper and lower bearing seats 3-9, the screw 3-6 can rotate stably.

[0034] The upper sleeve 4 is located outside each outer sleeve 3-4 and the side wall of the upper sleeve 4 is fixedly connected to each moving block 3-5 by a connecting pin 5, that is, the upper sleeve 4 is combined with each moving block 3-5 as a whole through the connecting pin 5. When each moving block 3-5 moves up and down, the upper sleeve 4 and its accessories move up and down accordingly.

[0035] In this embodiment, the hoisting frame 2 includes a frame top plate and a frame bottom plate, and a plurality of support connecting plates are installed between the edges of the frame top plate and the frame bottom plate to form a cage-shaped structure. The frame top plate is annular and is fixedly connected to the ship side base 1 by bolts. Furthermore, a side sealing plate (not shown in the figure) is installed between adjacent support connecting plates to seal the driving mechanism of the lifting drive assembly 3 inside to prevent foreign matter from entering the cage-shaped frame of the hoisting frame 2 and causing a drive jam problem.

[0036] In this embodiment, ear plates are provided on the side of the hoisting frame 2, the side of the lower pipe sleeve 9 and the side of the support rod 12, an upper safety rope 6 is provided between the ear plate of the hoisting frame 2 and the ear plate of the lower pipe sleeve 9, and a lower safety rope 10 is provided between the ear plate of the lower pipe sleeve 9 and the ear plate of the support rod 12. The purpose of providing the upper safety rope 6 and the lower safety rope 10 is to provide an additional insurance measure to connect adjacent components with safety ropes, so that in the event of an abnormal situation where a component falls off, no component will be completely detached to avoid losses.
