Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering technology, specifically to a water conservancy gate detection device. Background Technology

[0002] As the core load-bearing and flow-controlling components of water conservancy projects, the underwater part of the sluice gate is subjected to the dual effects of long-term immersion in moisture, water flow scouring, and complex water quality (such as water containing corrosive ions). The concrete is prone to carbonation reaction, which causes the pH value of the concrete pore solution to drop from strong alkalinity >12 to 8-9. This directly weakens the compressive strength of the concrete itself, damages the passivation film on the surface of the steel bars, causes steel bar corrosion, and further aggravates concrete cracking. This seriously threatens the durability and long-term operational safety of the sluice gate structure. Therefore, accurately detecting the carbonation depth of the underwater sluice gate concrete is a key technical link in assessing the health status of the sluice gate, predicting the structural life, and formulating targeted maintenance plans. Currently, underwater concrete carbonation depth testing relies on traditional, decentralized manual operations. This requires specialized divers to carry chisels, waterproof carbonation depth measuring instruments, phenolphthalein alcohol solution, and other independent tools. This method presents numerous problems. For example, the lack of an effective sealing structure, with the testing area connected to the water, makes it difficult to guarantee stable color development of the phenolphthalein solution within 3-5 minutes, leading to misjudgments of the carbonation boundary. Furthermore, the drilling tools lack slag removal design, leaving debris that obscures the color development interface. Additionally, divers are affected by buoyancy and low visibility, making it difficult to guarantee drilling verticality and depth, increasing testing errors. Moreover, the independent use of tools during operation requires frequent switching, which can easily cause testing point shifts, increasing testing costs and potentially interrupting testing, making it difficult to guarantee continuous testing over large areas.

A rack is fixedly installed on the top inner wall of the column frame, and the rack meshes with the gear.

[0009] Furthermore, two sets of arc-shaped push plates are fixedly connected to one end of the push frame and located on the outside of the drill rod; The inner wall of the guide tube is provided with two sets of slag discharge grooves; The two sets of arc-shaped push plates are respectively located in the two sets of slag discharge troughs; The arc-shaped pusher plate is slidably connected to the slag discharge trough and is used to discharge the gas in the slag discharge trough.

[0010] Furthermore, a plunger rod is slidably inserted inside the liquid guiding cylinder; A second cylinder is installed at one end of the liquid guide tube.

[0012] Furthermore, drainage channels are provided on both sides of the end face of the sealing disc; A one-way valve is fixedly installed on the inner wall of the end of the drainage channel; An air inlet channel is provided on the inner wall of the front end of the outer frame, and the air inlet channel is connected to the sealed area formed between the sealing plate, the outer frame, and the wall to be tested.

[0013] Furthermore, a worktable is fixedly installed on the outer wall of the sealing disc; Two sets of limiting tubes are fixedly connected to one end of the workbench relative to the sealing plate; A wall-supporting frame for supporting the carbonization depth measuring ruler is slidably inserted in the middle of the workbench and between the two sets of limiting tubes.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention integrates the entire process of "drilling-development-measurement" by setting up a negative pressure adsorption device and an execution device. The execution device has a built-in drilling component, which can drill measurement holes that meet the requirements on the wall to be tested. The liquid guide tube can spray a special phenolphthalein solution into the hole. The carbonization depth measuring ruler can detect the hole after development. The negative pressure adsorption device can stably fix the execution device on the wall of the underwater gate to form a uniform detection benchmark.

[0015] 2. This invention, by setting up a sealed area formed by the outer frame, sealing plate, and the wall to be tested, combined with air inlet channel, drainage channel, and one-way valve, can create a relatively dry testing environment underwater, isolating it from interference from external water bodies. Simultaneously, with the use of a specially formulated phenolphthalein solution, it ensures that the phenolphthalein solution can clearly reveal the boundary of the uncarbonized layer, fully meeting the stable color development requirement of 3-5 minutes, and completely avoiding misjudgment of the carbonized boundary due to water interference. Furthermore, the drilling assembly incorporates a slag discharge channel and an arc-shaped pusher plate. During drilling, the arc-shaped pusher plate moves synchronously with the pusher frame, pushing the gas and residual water in the slag discharge channel towards the borehole wall, simultaneously flushing and cleaning debris and powder from the borehole wall. This ensures a smooth borehole wall free of debris after drilling, providing a clean interface for the phenolphthalein solution to evenly cover the borehole wall, preventing incomplete color development caused by debris obstruction.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-13 The present invention provides a technical solution: A hydraulic gate detection device includes an outer frame 110, and further includes: The actuator 100 includes a drilling assembly 120 installed inside the outer frame 110 for drilling holes in the wall to be tested, and a sealing disc 111 located at one end of the drilling assembly 120 and on the inner front wall of the outer frame 110 for forming a sealed area between the front of the outer frame 110 and the wall to be tested. A liquid guide cylinder 150 fixedly connected to the inner wall of the sealing disk 111 for filling phenolphthalein solution; a carbonization depth measuring ruler 164 installed at one end of the sealing disk 111 located on the wall to be tested for measuring the carbonization depth of the wall after drilling; and a drive motor 113 installed at one end of the outer frame 110 relative to the sealing disk 111 for switching the positions of the drilling assembly 120, the liquid guide cylinder 150, and the carbonization depth measuring ruler 164. The negative pressure adsorption device 200 is used to adsorb the actuator 100 onto the wall of the gate to be tested by negative pressure, and the actuator 100 is installed in the middle of the negative pressure adsorption device 200.

[0020] It should be noted that by setting up the negative pressure adsorption device 200 and the execution device 100, the entire process of "drilling-developing color-measuring" is integrated. The execution device 100 has a built-in drilling component 120, which can drill measurement holes that meet the requirements. Subsequently, the drive motor 113 drives the sealing disc 111 to rotate and switch sequentially. A special phenolphthalein solution is sprayed into the hole through the liquid guide tube 150. The carbonization depth measuring ruler 164 is used to detect the colored hole. There is no need for divers to frequently change tools, avoiding point deviation caused by tool switching. At the same time, multiple measurement points can be continuously detected based on the same adsorption fixed point, effectively reducing the risk of detection interruption. It is suitable for the detection needs of large-area gates and significantly improves detection efficiency and point consistency.

[0021] As an improvement, such as Figures 8-13 As shown, the drilling assembly 120 includes: The column frame 121 is fixedly connected to one end of the sealing disc 111; Arc-shaped positioning plates 122 are fixedly installed on both sides of the column frame 121 by inserting reinforcing bars; The push-receiving frame 124 is inserted into the interior of the column frame 121, and the push-receiving frame 124 is slidably connected to the arc-shaped positioning plate 122; Gear 125, gear 2126, gear 3, and helical gear 3127 are rotatably mounted inside the push frame 124. Gear 125 meshes with gear 2126, and gear 2126 and helical gear 3127 are coaxially arranged. Helical gear 128 is located inside the push frame 124 and meshes with helical gear 127. The drill rod 129 is fixedly connected to one end of the helical gear 128, and the drill rod 129 is rotatably connected to the inside of the push frame 124.

[0022] In this invention, the drive cylinder 142 pushes the push rod 141, causing the push rod 141 to push the push frame 124 and the drill rod 129 outward, so that the drill rod 129 contacts the wall. When the push rod 141 drives the push frame 124 to move forward, the rack 143 drives the gear 125 to rotate under the force of the rack 143. The gear 125 drives the gear 2 126 to rotate. The gear 2 126 drives the helical gear 3 127 to rotate through the shaft, so that the helical gear 3 127 drives the helical gear 4 128 to rotate. The helical gear 4 128 drives the drill rod 129 to rotate. At this time, the drill rod 129 can perform drilling operation on the wall surface to be tested.

[0023] Furthermore, such as Figure 9 As shown, the arc-shaped positioning plate 122 has two sets of slots 123 inside; Two sets of clamping plates 133 are fixedly connected to both sides of the push frame 124; The card plate 133 corresponds one-to-one with the card slot 123 and slides with the card slot 123. It is used to limit and guide the movement of the push frame 124 to ensure that the push frame 124 will not deflect when it slides in the column frame 121.

[0024] Furthermore, such as Figures 9-13 As shown, the drilling assembly 120 further includes: The guide tube 130 is fixedly connected to one end of the column frame 121 and located outside the drill rod 129. The drill rod 129 rotatably passes through the interior of the guide tube 130. The positioning tube 140 is fixedly connected to one end of the column frame 121 opposite to the guide tube 130; Cylinder 142 is installed at one end of the positioning tube 140 opposite to the column frame 121; Push rod 141 is slidably inserted into the positioning tube 140. One end of push rod 141 is fixedly connected to the output end of cylinder 142, and the other end is fixedly connected to the push frame 124, for pushing and adjusting the push frame 124. The rack 143 is fixedly installed on the top inner wall of the column frame 121, and the rack 143 meshes with the gear 125.

[0025] Among them, such as Figures 11-12 As shown, two sets of arc-shaped push plates 132 are fixedly connected to one end of the push frame 124 and to the outside of the drill rod 129; The inner wall of the guide tube 130 is provided with two sets of slag discharge grooves 131; The two sets of arc-shaped push plates 132 are respectively located in the two sets of slag discharge troughs 131; The arc-shaped pusher plate 132 is slidably connected to the slag discharge trough 131 to discharge the gas in the slag discharge trough 131.

[0026] As an improvement, such as Figure 7 As shown, a plunger rod 151 is slidably inserted into the liquid guide tube 150; A cylinder 153 is installed at one end of the liquid guide tube 150. The output end of the cylinder 153 is fixedly connected to one end of the plunger rod 151 for pushing and pulling adjustment of the plunger rod 151. The liquid guide tube 150 is equipped with a liquid outlet pipe 152 at one end relative to the cylinder 153, which is used to discharge the phenolphthalein solution in the liquid guide tube 150.

[0027] Furthermore, a linkage column 112 is fixedly connected to the center of one end of the sealing disc 111; The guide tube 130 and the outlet of the liquid outlet tube 152 are located on the same circle, and the circle coincides with the center of the sealing disc 111.

[0028] Furthermore, drainage channels 114 are provided on both sides of the end face of the sealing disc 111; A one-way valve 116 is fixedly installed on the inner wall of the end of the drainage channel 114; An air inlet channel 115 is provided on the inner wall of the front end of the outer frame 110. The air inlet channel 115 is connected to the sealed area formed between the sealing plate 111, the outer frame 110, and the wall to be tested.

[0029] It should be noted that: gas is injected into the sealed area formed between the sealing disc 111, the front end of the outer frame 110, and the wall to be tested through the air inlet channel 115, and water in the sealed area is discharged through the drain channel 114 and the one-way valve 116, creating a relatively dry environment in the sealed area. After drilling is completed, the drive motor 113 drives the sealing disc 111 to rotate through the linkage column 112, causing the liquid outlet pipe 152 to rotate to the drilled hole. At this time, the drive cylinder 153 drives the plunger rod 151. The liquid guide tube 150 is moved within the liquid guide tube 150, thereby discharging the specially prepared phenolphthalein solution within the liquid guide tube 150 into the hole through the liquid outlet tube 152, so that the phenolphthalein solution covers the entire hole wall and does not flow out of the hole wall. After waiting for 3-5 minutes, observe the color development result of the hole. Uncarbonized concrete (pH value > 10) will react with phenolphthalein and turn red, while carbonized concrete (pH value ≤ 9) will not undergo a color development reaction due to the disappearance of alkalinity (and will be colorless). If a "red-colorless" boundary appears on the hole wall, the boundary line is the interface between the carbonized layer and the uncarbonized layer.

[0030] Among them, such as Figure 3 , Figure 5 As shown, a workbench 160 is fixedly installed on the outer wall of the sealing disc 111; Two sets of limiting tubes 161 are fixedly connected to one end of the workbench 160 relative to the sealing disc 111; A wall support frame 162 for supporting the carbonization depth measuring ruler 164 is slidably inserted in the middle of the workbench 160 and between the two sets of limiting tubes 161. A spring 163 is inserted inside the limiting tube 161. One end of the spring 163 is fixedly connected to the bottom of the limiting tube 161, and the other end is fixedly connected to the wall support frame 162. The carbonization depth measuring ruler 164 is fixedly connected to the inner wall of the wall support frame 162; A cylinder 165 is fixedly installed inside the sealing disc 111, and the output end of the cylinder 165 is fixedly connected to the carbonization depth measuring ruler 164.

[0031] It should be noted that after the area of ​​the hole to be tested is colored, the drive motor 113 drives the carbonization depth measuring ruler 164 to switch to the colored area. After that, the drive cylinder 165 drives the carbonization depth measuring ruler 164 to extend vertically into the hole from the edge of the drill hole and measure the distance from the surface to the colorization boundary line, which is the carbonization depth of a single measuring point. At the same time, 2-3 additional measurements are taken around the drill hole, and the arithmetic mean of all measuring points is taken as the carbonization depth of the test area.

[0032] It should be noted that the working principle of this invention is as follows: Personnel diving to place the device onto the underwater wall of the gate to be tested. The negative pressure adsorption device 200 causes the actuator 100 to adhere to the wall. Then, air is injected through the air inlet channel 115 into the sealed area formed between the sealing disc 111, the front end of the outer frame 110, and the wall to be tested. Water within the sealed area is discharged through the drainage channel 114 and the one-way valve 116, creating a relatively dry environment. Subsequently, the drive cylinder 142 pushes the push rod 141, causing the push rod 141 to push the push frame 12 outwards. 4. The drill rod 129 is brought into contact with the wall. When the push rod 141 drives the push frame 124 to move forward, under the force of the rack 143 on the gear 125, the rack 143 drives the gear 125 to rotate. The gear 125 rotates through the gear 2 126. The gear 2 126 drives the helical gear 3 127 to rotate through the shaft. The helical gear 3 127 drives the helical gear 4 128 to rotate. The helical gear 4 128 drives the drill rod 129 to rotate. At this time, the drill rod 129 performs the drilling operation on the wall to be tested. The drilling depth is controlled at 20-30mm to ensure that the drilled hole can exceed the thickness of the carbonation layer. Underwater concrete carbonation depth is usually shallow, generally less than or equal to 5mm, to avoid drilling through the protective layer. Because some liquid water remains in the underwater slag discharge trough 131, while the drill rod 129 is drilling, the pusher 124 drives the arc-shaped push plate 132 to move within the slag discharge trough 131, discharging the gas from the slag discharge trough 131. This allows the liquid water and gas in the slag discharge trough 131 to clean the debris and powder inside the hole wall, ensuring a smooth hole wall free of residual impurities. After drilling is completed, the drive motor 113 drives the sealing disc 111 to rotate via the linkage column 112, causing the liquid outlet pipe 152 to switch to the drilled hole. At this time, the drive cylinder 153 drives the plunger rod 151 to move within the liquid guide cylinder 150, thereby discharging the special phenolphthalein solution in the liquid guide cylinder 150 through the liquid outlet pipe 152 to the hole, ensuring that the phenolphthalein solution covers the entire hole wall without flowing out. After waiting 3-5 minutes, observe the color development results of the hole (uncarbonized concrete (pH value > 10) will react with phenolphthalein to develop color). Red, carbonized concrete (pH value ≤ 9) does not undergo a color reaction due to the disappearance of alkalinity (it is colorless); if a "red-colorless" boundary appears on the hole wall, the boundary line is the interface between the carbonized layer and the uncarbonized layer. After the color development is completed, drive motor 113 again to switch the carbonization depth measuring ruler 164 to the color development area. Then, drive cylinder three 165 to drive the carbonization depth measuring ruler 164 to extend vertically into the hole from the edge of the borehole and measure the distance from the "surface to the color development boundary line", which is the carbonization depth of a single measuring point. In order to avoid uneven local carbonization, 2-3 points can be measured at the same time around the borehole. Take the arithmetic mean of all measuring points as the carbonization depth of the measuring area. If the deviation of a single measuring point from the average value is > 2 mm, the borehole needs to be re-drilled and measured. After the measurement of the borehole is completed, select multiple measuring points on the wall and repeat the above steps to measure the concrete carbonization depth of the underwater wall.

[0033] It should be added that: when preparing phenolphthalein solution, a high concentration of alcohol solvent should be used: using 95% ethanol instead of water can significantly improve the solubility of phenolphthalein and reduce the effect of water dilution. At the same time, the concentration of phenolphthalein should be controlled: using 1%-2% phenolphthalein alcohol solution (1-2g phenolphthalein dissolved in 100mL 95% ethanol) can ensure the colorimetric sensitivity while avoiding fading caused by excessive concentration.
