Description

Technical Field

[0001] The present invention relates to the technical field of composite hose measurement, and specifically to a high-performance composite hose measurement device for ocean engineering. Background Art

[0002] The high-performance composite hose for seawater transportation is a pipeline designed specifically for the ocean environment, with excellent corrosion resistance, pressure resistance and adaptability. The high-performance composite hose usually consists of a corrosion-resistant inner layer, a reinforcing structure intermediate layer and a protective outer layer, ensuring long-term stable operation in the harsh ocean environment and being widely used in liquid transportation in ocean engineering.

[0003] However, when the existing pressure test pump only detects the pressure resistance of one composite hose each time, the operator needs to repeatedly start and stop the pressure test pump, which is likely to increase the detection time; and during the process of detecting one by one, the test conditions of each hose may vary, thus resulting in the lack of comparability and consistency of the detection results; in addition, multiple composite hoses are stacked near the pressure test pump, and the untested ones are likely to be mixed with the tested ones, making it difficult for the operator to distinguish, which is not conducive to improving the measurement efficiency of the composite hose. Summary of the Invention

[0006] The supporting mechanism includes a sliding frame and a fixing plate. The sliding frames are provided at the bottoms of several composite hoses. A connecting shaft and a fixing plate are fixedly connected between two sliding frames. A rotating rod is rotatably connected to the connecting shaft, and the rotating rod is in contact with the side wall of the composite hose. A groove is provided on the sliding frame.

[0007] Specifically, the installation mechanism includes a pressure gauge and an inlet pipe. The pressure gauge is fixedly installed on the pressure test pump, and the inlet pipe is fixedly installed on the pressure gauge and is communicated with the inside of a splitter.

[0008] Specifically, the limiting mechanism includes a bracket and a fixing rod, a bracket is provided at the bottom end of the splitter, an upper limiting block and a fixing rod are provided on the bracket, a support rod is fixedly installed between the two limiting blocks, a clamping rod is clamped and connected on the support rod, the two groups of limiting blocks are symmetrically arranged, the splitter is located between the clamping rod and the support rod, and the part where the clamping rod contacts the splitter is arranged in an arc surface structure, the limiting mechanism also includes a clamping slot and a guide rod, a plurality of clamping slots are provided on the bracket, a guide rod is rotatably installed at the part of the bracket near the clamping slot, the part of the bracket near the clamping slot is arranged in an inclined structure, and the guide rod is located on the side of the bracket away from the inlet pipe.

[0009] Specifically, the sealing mechanism includes an outlet pipe and a composite pipe cover, the splitter is connected to a plurality of outlet pipes, a composite pipe cover is fixedly installed on the outlet pipe, the composite pipe cover is fixedly connected to the composite hose through a plurality of limit bolts, a sleeve and a sealing gasket are fixedly installed on the composite pipe cover, a plurality of the sealing gaskets are equidistantly arranged in a ring shape, and the sealing gasket is arranged in an arc-shaped structure, the sealing gasket is located on the side of the composite pipe cover away from the outlet pipe, the sleeve is located on the side of the composite pipe cover close to the composite hose, and the sleeve and the composite hose are snap-fitted and connected.

[0010] Specifically, the fixing mechanism includes a fixing seat and a roller. Several groups of fixing seats are equidistantly fixedly installed on one fixing rod. The sliding frame is slidably connected to the fixing seat. Several rollers are rotatably installed on the fixing seat. The rollers are rollingly connected to the sliding frame. A slot is provided in the fixing seat.

[0011] The beneficial effects of the present invention are:

[0012] (1) The high-performance composite hose measuring device for marine engineering described in the present invention assembles a sealing mechanism and a composite hose together, so that the interiors of multiple composite hoses can be connected to the interior of the installation mechanism. The setting of the limiting mechanism can also guide the sealing mechanism to prevent the connection components of multiple sealing mechanisms from being mixed together, that is, before the operator performs a pressure test on the composite hose, he can first assemble one end of the composite hose with the sleeve fixed on the composite pipe cover. Since the diameter of the sleeve is equal to the inner diameter of the composite hose, when the composite hose hits the sealing gasket fixed on the composite pipe cover, it can be engaged with the sleeve, and then a tool is used to fix a plurality of limiting bolts on the composite pipe cover and the composite hose. The inside of the composite hose can be sealed; and the setting of the sealing gasket is also convenient for improving the sealing between the composite pipe cover and the composite hose, which is beneficial to preventing fluid leakage in the composite hose; an outlet pipe is installed on the side of the composite pipe cover away from the composite hose, and several outlet pipes are connected to the inside of the splitter, and then the fluid can be evenly discharged into the inside of the composite hose through the splitter; and the outlet pipe is in contact with the guide rod installed on the bracket, and a slot is provided at the position of the bracket close to the guide rod. When the outlet pipe is installed, it is in the slot position, which further prevents multiple outlet pipes from piling up during the test, making it inconvenient for the operator to check, and the setting of the guide rod also reduces the contact area between the outlet pipe and the guide rod during the movement of the composite hose.

[0013] (2) The high-performance composite hose measuring device for marine engineering described in the present invention places the installed composite hose on the support mechanism engaged in the fixing mechanism. The composite hose can be supported during the inspection process by the support mechanism, and multiple composite hoses can also be placed separately, that is, the assembled composite hose is placed on the sliding frame. Since the two sliding frames are connected by a coupling and a fixing plate, when the composite hose is located at the top of the sliding frame, its side wall will contact the rotating rod rotatably installed on the coupling. When the operator rotates to check the composite hose, the rotating rod will rotate along the side wall of the coupling under the driving action of friction, thereby facilitating the flipping of the composite hose; the sliding frame is slidably installed inside the two fixed seats. Since rollers are rotatably installed inside the fixed seats, when it is necessary to check the composite pipe cover, the handle fixed on the side wall of the sliding frame can be pulled to slide in the slot provided in the fixed seat. The roller contacts the sliding frame in the sliding state and then starts to rotate, thereby facilitating the reduction of the friction between the sliding frame and the fixed seat, which is conducive to quickly checking the composite pipe cover.

[0014] (3) A high-performance composite hose measuring device for ocean engineering according to the present invention. When the test press is started, the fluid can be evenly distributed into the composite hoses through the installation mechanism, thereby facilitating the pressure test detection of multiple composite hoses simultaneously. That is, during the detection, open the water injection valve of the pressure test pump, inject water into all the composite hoses, and at the same time discharge the air in the composite hoses through the exhaust ports of the splitter to ensure that the composite hoses are filled with water and there are no bubbles; then start the pressure test pump, gradually increase the pressure to the test pressure (usually 1.5 times the normal pressure), and maintain the pressure stable for a period of time (such as 10 minutes), observe the change of the pressure gauge to ensure that the pressure of each composite hose reaches the requirements; during the pressurization process, check whether there is leakage or abnormality at the interface of each composite hose, and record the change of the pressure value; if the pressure drop exceeds the allowable range (such as 0.05 MPa), it is necessary to check for problems; after the test is completed, slowly open the pressure relief switch of the pressure test pump to release the pressure in the composite hoses to ensure safe operation; thus, the pressure test detection of multiple composite hoses can be carried out simultaneously through the splitter, which is beneficial to improving the efficiency and ensuring the sealing performance and pressure resistance of each composite hose.

Detailed implementation manners

[0025] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0026] As Figure 1 , Figure 2 , Figure 4 and Figure 8 shown, a high-performance composite hose measuring device for ocean engineering according to the present invention includes a pressure test pump 1, and an installation mechanism 2 is fixed on the pressure test pump 1; the installation mechanism 2 is in contact with a limiting mechanism 3; and a sealing mechanism 4 is communicated with the installation mechanism 2; a composite hose 5 is fixed on the sealing mechanism 4; a plurality of groups of fixing mechanisms 6 are equidistantly installed on the limiting mechanism 3; and a support mechanism 7 is slidably installed in the fixing mechanism 6.

[0027] Specifically, as Figure 1 , Figure 2 , Figure 4 and Figure 5 shown, the support mechanism 7 includes a sliding frame 701 and a fixing plate 704. The bottom ends of a plurality of the composite hoses 5 are provided with sliding frames 701. A coupling shaft 703 and a fixing plate 704 are fixedly connected between two sliding frames 701. A rotating rod 702 is rotatably connected to the coupling shaft 703. The rotating rod 702 is in contact with the side wall of the composite hose 5. A groove 705 is provided on the sliding frame 701. After the assembled composite hose 5 is placed on the sliding frame 701, its side wall will be in contact with the rotating rod 702 rotatably installed on the coupling shaft 703. When an operator rotates to check the composite hose 5, the rotating rod 702 will rotate along the side wall of the coupling shaft 703 under the driving action of friction, thereby facilitating the flipping of the composite hose 5.

[0028] Specifically, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7and Figure 8 As shown, the installation mechanism 2 includes a pressure gauge 201 and an inlet pipe 202. The pressure gauge 201 is fixedly installed on the pressure test pump 1. The pressure test pump 1 is started, and the pressure is gradually increased to the test pressure. The pressure is kept stable for a period of time, and the changes in the pressure gauge 201 are observed to ensure that the pressure of each composite hose 5 meets the requirements; the inlet pipe 202 is fixedly installed on the pressure gauge 201, and the inlet pipe 202 is connected to the inside of the splitter 203. The water injection valve of the pressure test pump 1 is opened to inject water into all the composite hoses 5. At the same time, the air in the composite hose 5 is discharged through the exhaust port of the splitter 203 to ensure that the composite hose 5 is full of water and free of bubbles.

[0029] Specifically, Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the limiting mechanism 3 includes a bracket 304 and a fixing rod 305, the bottom end of the splitter 203 is provided with a bracket 304, an upper limit block 302 and a fixing rod 305 of the bracket 304, a support rod 303 is fixedly installed between the two limiting blocks 302, and a clamping rod 301 is clamped and connected on the support rod 303, the two groups of limiting blocks 302 are symmetrically arranged, the splitter 203 is located between the clamping rod 301 and the support rod 303, and the part where the clamping rod 301 contacts the splitter 203 is arranged in an arc surface structure, the limiting mechanism 3 also includes a clamping groove 306 and a guide rod 30 7. The bracket 304 is provided with a plurality of slots 306. A guide rod 307 is rotatably mounted on a portion of the bracket 304 near the slots 306. The outlet pipe 401 contacts the guide rod 307, which prevents a plurality of outlet pipes 401 from piling up during the test, making it inconvenient for operators to check them. The setting of the guide rod 307 also reduces the contact area between the outlet pipe 401 and the guide rod 307 during the movement of the composite hose 5. The portion of the bracket 304 near the slots 306 is arranged in an inclined structure, and the guide rod 307 is located on the side of the bracket 304 away from the inlet pipe 202.

[0030] Specifically, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the sealing mechanism 4 includes an outlet pipe 401 and a composite pipe cover 402. The splitter 203 is connected with a plurality of outlet pipes 401. The outlet pipe 401 is fixedly mounted with a composite pipe cover 402. The composite pipe cover 402 is fixedly connected to the composite hose 5 through a plurality of limit bolts 403. The limit bolts 403 are fixed to the composite pipe cover 402 and the composite hose 5 using a tool, so that the interior of the composite hose 5 can be sealed; a sleeve 404 and a sealing gasket 405 are fixedly mounted on the composite pipe cover 402. One end of the composite hose 5 is assembled with the sleeve 404. Since the diameter of the sleeve 404 is equal to the inner diameter of the composite hose 5, when the composite hose 5 hits the sealing gasket 405, the composite hose 5 is sealed. When the composite pipe cover 402 is opened, the composite pipe cover 402 and the composite hose 5 can be connected by snapping together with the sleeve 404; the plurality of sealing pads 405 are arranged in an annular shape with equal distance, and the sealing pads 405 are arranged in an arc-shaped structure. The arrangement of the sealing pads 405 is also convenient for improving the sealing between the composite pipe cover 402 and the composite hose 5, which is beneficial for preventing the fluid in the composite hose 5 from leaking; the sealing pad 405 is located on the side of the composite pipe cover 402 away from the outlet pipe 401, and the plurality of outlet pipes 401 are connected to the inside of the splitter 203, so that the fluid can be evenly discharged into the inside of the composite hose 5 through the splitter 203; the sleeve 404 is located on the side of the composite pipe cover 402 close to the composite hose 5, and the sleeve 404 and the composite hose 5 are snap-connected.

[0031] Specifically, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the fixing mechanism 6 includes a fixing seat 601 and a roller 602, a plurality of groups of fixing seats 601 are fixedly installed at equal intervals on one of the fixing rods 305, the sliding frame 701 is slidably connected to the fixing seat 601, and a plurality of rollers 602 are rotatably installed on the fixing seat 601. When the composite pipe cover 402 needs to be checked, the sliding frame 701 can be slid in the fixing seat 601 by pulling the handle fixed on the side wall of the sliding frame 701, and the roller 602 contacts the sliding frame 701 and starts to rotate, thereby reducing the friction between the sliding frame 701 and the fixing seat 601; the roller 602 is rollingly connected to the sliding frame 701, and a slot 603 is provided in the fixing seat 601, and the slot 603 limits the sliding frame 701 to prevent the sliding frame 701 from shifting during movement.

[0032] When the present invention is in use, first, before an operator performs a pressure test on the composite hose 5, one end of the composite hose 5 can be assembled with the sleeve 404 fixed on the composite pipe cap 402. Since the diameter of the sleeve 404 is equal to the inner diameter of the composite hose 5, when the composite hose 5 abuts against the gasket 405 fixed on the composite pipe cap 402, it can be snap-connected with the sleeve 404. Then, a tool is used to fix a number of limit bolts 403 on the composite pipe cap 402 and the composite hose 5, thereby sealing the interior of the composite hose 5; and the setting of the gasket 405 also facilitates improving the sealing performance between the composite pipe cap 402 and the composite hose 5, which is beneficial to preventing the fluid in the composite hose 5 from leaking. An outlet pipe 401 is installed on the side of the composite pipe cap 402 facing away from the composite hose 5, and a number of outlet pipes 401 are all communicated with the interior of the splitter 203. Thus, the fluid can be evenly discharged into the interior of the composite hose 5 through the splitter 203; and the outlet pipe 401 contacts the guide rod 307 installed on the bracket 304. A slot 306 is provided at the part of the bracket 304 close to the guide rod 307. When the outlet pipe 401 is installed, it is located at the slot 306 part, further preventing the accumulation of multiple outlet pipes 401 during the test process, which is not convenient for the operator to view. And the setting of the guide rod 307 also reduces the contact area between the outlet pipe 401 and the guide rod 307 during the movement of the composite hose 5.

[0033] Place the assembled composite hose 5 on the sliding frame 701. Since the two sliding frames 701 are connected by a coupling shaft 703 and a fixing plate 704, when the composite hose 5 is located at the top of the sliding frame 701, its side wall will contact the rotating rod 702 rotatably installed on the coupling shaft 703. When the operator rotates to view the composite hose 5, the rotating rod 702 will rotate along the side wall of the coupling shaft 703 under the driving action of friction, thus facilitating the flipping of the composite hose 5. The sliding frame 701 is slidably installed inside the two fixed seats 601. Since a roller 602 is rotatably installed inside the fixed seat 601, when it is necessary to view the composite pipe cap 402, by pulling the handle fixed on the side wall of the sliding frame 701, it can slide at the slot 603 provided inside the fixed seat 601, and the roller 602 contacts the sliding sliding frame 701 and then starts to rotate, thereby facilitating the reduction of the friction between the sliding frame 701 and the fixed seat 601, which is beneficial to quickly view the composite pipe cap 402.

[0034] During detection, open the water injection valve of the pressure test pump 1 to inject water into all composite hoses 5. At the same time, discharge the air in the composite hoses 5 through the exhaust port of the splitter 203 to ensure that the composite hoses 5 are filled with water and there are no bubbles. Then start the pressure test pump 1, gradually increase the pressure to the test pressure (usually 1.5 times the normal pressure), and maintain the pressure stable for a period of time (such as 10 minutes). Observe the change of the pressure gauge 201 to ensure that the pressure of each composite hose 5 reaches the requirement. During the pressurization process, check whether there is leakage or abnormality at the interface of each composite hose 5 and record the change of the pressure value. If the pressure drop exceeds the allowable range (such as 0.05 MPa), the problem needs to be investigated. After the test is completed, slowly open the pressure relief switch of the pressure test pump 1 to release the pressure in the composite hoses 5 to ensure safe operation. Furthermore, multiple composite hoses 5 can be subjected to pressure test detection simultaneously through the splitter 203, which is beneficial to improving efficiency and ensuring the sealing performance and pressure resistance of each composite hose 5.
