Description

A kind of traction walking system for water working platform

Technical field

The invention relates to the technical field of water operations in hydraulic engineering, and in particular to a traction and walking system for a water operation platform.

Background technique

In recent years, many water bodies have experienced eutrophication. It refers to the fact that under the influence of human activities, nitrogen, phosphorus and other nutrients needed by organisms enter large amounts of slow-flowing water bodies such as lakes, rivers, and bays, causing algae and other plankton to grow. Rapid reproduction, a decrease in dissolved oxygen in water, deterioration of water quality, and mass death of fish and other organisms. Among them, phytoplankton reproduces in large numbers, forming an algae bloom (a natural ecological phenomenon in which algae reproduce in large quantities in fresh water bodies). Eutrophication will Affecting the water quality of the water body will reduce the transparency of the water, making it difficult for sunlight to penetrate the water layer, thereby affecting the photosynthesis of plants in the water, and may cause a supersaturated state of dissolved oxygen. Supersaturation of dissolved oxygen and low dissolved oxygen in water are harmful to aquatic animals, causing mass deaths of fish. At the same time, due to eutrophication of the water body, a large number of algae with cyanobacteria and green algae as the dominant species grow on the surface of the water body, forming a layer of "green scum", causing the organic matter accumulated at the bottom to decompose under anaerobic conditions to produce harmful gases and some Biotoxins produced by plankton can also harm fish. Because eutrophic water contains nitrates and nitrites, humans and animals may become poisoned and sick if they drink water with content exceeding a certain level for a long time. After the "green scum" is formed, the underwater algae will breathe oxygen in the water because they are not exposed to sunlight, and cannot carry out photosynthesis. The oxygen in the water will gradually decrease, and aquatic organisms will die due to lack of oxygen. The dead algae and organisms will undergo oxidation in the water. At this time, the water body will become very smelly, and the water resources will be polluted and cannot be reused. The occurrence of cyanobacteria blooms in reservoirs is not terrible, because naturally growing living cyanobacteria will not pollute the water quality; however, if the treatment is not effective, they will accumulate in the waters in front of the dam (downwind), and then die and rot, polluting the water quality. Therefore, the existing blue-green algae protection measures at the water outlet and temporary emergency algae removal measures cannot meet the needs of preventing and controlling blue-green algae disasters, and a stronger defense front must be built.

In response to the above problems, the water management department needs to implement corresponding anti-pollution measures through water operations. For example, through water operations such as underwater trenching, underwater anchoring, and linear layout, blocking defense lines are set up for pollution prevention. Common ones are based on water operations. Floating platforms for water operations. There are generally two methods of platforms currently used. One is a floating platform that is fixed by anchor ropes and connected to a fixed structure on the shore to position the platform. This method has a simple structure and is very convenient to install and operate. The disadvantage is that it can only be used in In waters with slow flow speed and small wind and waves, once it is used in water areas with turbulent flow speed and large wind and waves, the floating platform is extremely difficult to stabilize, and the accuracy of the operation cannot be guaranteed at all. Moreover, it needs to lift the anchor when it needs to be moved, and the process is more complicated; the second is to directly By fixing the platform to the bottom of the water, the floating platform structure of this method is stable and can ensure the accuracy of construction. However, because it involves the construction of a fixed structure, the construction is difficult, and it is difficult to install and disassemble, making it difficult to promote and use it on a large scale.

It is widely used by modern large and medium-sized ships. The chain link of the unblocked anchor chain has no rungs and can be used on small ships. In this embodiment, in order to realize the walking cooperation between the traction chain 101 and the driving part 201, the traction chain 101 adopts an unblocked anchor with a certain weight. The chain is fixed to the fixing component 102 on the shore through one end, and the other end is pulled and straightened by the anchor ship and fixed on the fixing component 102 on the opposite shore. Here, one end of the unblocked anchor chain is stowed in the anchor ship. state, as the anchor ship moves forward, it is slowly released. During the process of the anchor ship moving forward, the unblocked anchor chain is always in a taut and straightened state. When the anchor ship reaches the designated opposite shore, the length of the unblocked anchor chain that is released is the same as The distance between the two banks corresponds to each other. At this time, the other end of the unblocked anchor chain is fixed on the opposite bank through the fixing assembly 102 to realize the straightening of the unblocked anchor chain on the water surface to form the traction chain 101, which is also used as the floating platform 200.

Therefore, the difference between this embodiment and the above-mentioned embodiment is that the water working platform traction walking system also includes a water level measurement unit 300. The water level measurement unit 300

It is arranged at both ends of the traction chain 101, floats on the water surface S, and the bottom end is connected to the traction chain 101 that sinks to the bottom of the water. specific,

Figures 7 to 16 are schematic diagrams of the overall structure of the traction and walking system of the water working platform according to the fourth embodiment of the present invention. In the above embodiment, the water level measurement unit 300 is disposed on the water surface with a certain buoyancy, and can be inflated, for example. type floating body, in actual operation, changes in the water level will cause the pulling force between the water level measuring unit 300 and the traction chain 101 at the bottom to become larger or smaller, so that the water level measuring unit 300 can rise or fall with changes in the water level. , and the traction chain 101 that sinks to the bottom of the water will not move due to its large weight, so the distance between the water level measurement unit 300 and the traction chain 101 will change accordingly, and the depth of the water level can be measured based on this change in distance. At the same time, when the water level measuring unit 300 floats on the water, it will be affected by the wind and deflect, which will also cause the water level measuring unit 300 to deflect, affecting the measurement effect.

It should be noted here that the part of the damping rotating shaft 301a located between the partition plates 301a-1 can rotate relative to the damping matching area. That is, the measuring roll cloth 401 is rolled on the damping shaft 301a according to this rotation, and a recovery spring is also provided in this rotation mode, so that after relative rotation, it has a tendency to return to the original state, that is, the rotation force. The thread 301a-2 and the slot 301a-3 are both provided at both ends of the damping shaft 301a outside the partition plate 301a-1, and the thread 301a-2 is in the shape of a ring, extending inward from the outermost edge of the damping shaft 301a without being separated from it. The plates 301a-1 are in side contact, that is, there is a blank space between them, and the slot 301a-3 is provided along the spiral extension direction of the thread 301a-2 and resists the partition plate 301a-1. Referring to Figures 9 and 10, the damping block 301b is sleeved on the damping shaft 301a, and the outer end is limited by a limit screw 301d. The limit screw 301d can cooperate with the thread 301a-2 to change the distance, thereby adjusting the distance between the damping block 301b and The distance between the dividing plates 301a-1; and the damping rotating sleeve 301c is set between the damping blocks 301b to achieve damping cooperation.

Further, as shown in Figure 11, the damping block 301b also includes inner convex strips 301b-1 and outer convex strips 301b-2. In this embodiment, several inner convex strips 301b-1 are correspondingly arranged in the slot 301a-3 to achieve The damping block 301b can only move along the direction in which the damping rotating shaft 301a extends, and cannot rotate relative to the damping rotating shaft 301a. The damping rotating sleeve 301c is set on the damping block 301b, and one end is fixedly connected to the partition plate 301a-1. This can be realized by welding or an integrated structure. Furthermore, a damping portion 301c- is also provided on the inner wall of the damping rotating sleeve 301c. 1 and the transparent notch 301c-2, when the damping shaft 301a rotates, several outer protrusions 301b-2 and the damping portion 301c-1 achieve damping cooperation through the action of friction. In this embodiment, shaft holes 301c-21 are symmetrically provided on the inner side walls of the transparent slot 301c-2, and the shaft holes 301c-21 can interact with the wind lock module 303.

Referring to Figure 13, a schematic diagram of the overall structure of the lifting module 302 of the present invention is shown, which is a pontoon structure. Specifically, the lifting module 302 includes an accommodation space 302a, a skirt cloth gap 302b, an air inlet assembly 302c, a water inlet assembly 302d, and a drainage assembly 302e. The measuring roll cloth 401 is wrapped around the damping rotating shaft 301a. Both of them are arranged in the accommodation space 302a. Rotate, and the measuring roll cloth 401 is unfolded downward through the skirt cloth gap 302b. The unfolded part is located in the water to block the line of defense, and the partition plates 301a-1 are fixedly installed at both ends of the pontoon. Simply put, the lifting module 302 is actually a damping module. 301 support fixed structure. In order to realize the lifting protection of the lifting module 302, in this embodiment, the pontoon is a hollow structure, and air and water can be admitted inside. The buoyancy of the pontoon on the water can be set by the water volume and gas ratio in the hollow structure. Further, , the air inlet assembly 302c and the water inlet assembly 302d are disposed at the top of the lifting module 302, and the drainage assembly 302e is disposed at the bottom of the lifting module 302. In this embodiment, the air inlet assembly 302c can be an air pump, and the water inlet assembly 302d and the drainage assembly 302e Can be a water pump. Its working principle is: on the one hand, when encountering ice on the water surface or other severe weather, the water level measuring unit 300 needs to be placed below the water surface, and the ratio of water volume and gas content in the hollow structure of the buoy is controlled through the air inlet assembly 302c and the water inlet assembly 302d. , adjust the buoyancy of the buoy to make it rise or sink. On the other hand, by adjusting the damping size (the damping size can be set in advance, and the friction force is adjusted through the rubber material or the extrusion force), the traction force generated between the buoyancy force of the float and the measuring cloth 401 is equal to the damping size. At this time The buoy can just float on the water. When the water level rises due to bad weather, the traction force generated by the buoyancy force is greater than the damping force. At this time, the damping shaft 301a rotates, and the part of the measuring roll cloth 401 is pulled out until the traction force matches the damping force again. The forces are equal in size, realizing automatic adjustment of the water level measuring unit 300 to adapt to changes in water level, and protecting the water level measuring unit 300 from sinking in cold weather.

Referring to Figures 14 to 16, further, in order to prevent the water level measurement unit 300 from being blown by strong wind force in the water environment, causing the blocking defense line formed on the water surface to deform, thereby affecting the blocking effect. Therefore, in this embodiment, a wind lock module 303 is also provided. When strong wind is encountered, the damping module 301 is locked, and when the water level rises, the damping module 301 can be unlocked. Therefore, the locking module 303 also includes a wind offset. It should be noted that both the plate 303a and the locking trigger block 303b are made of elastic material such as rubber and have a certain degree of elasticity. Specifically, the wind deflection plate 303a includes a wind plate 303a-1 that increases the contact area with the wind and a latch 303a-2 that locks the locking trigger block 303b. The wind plate 303a-1 is installed vertically on the damping rotation sleeve 301c. The outer side of the upper end, and the latch pins 303a-2 are provided on both sides of the wind plate 303a-1.

The locking trigger block 303b includes a floating block 303b-1, a spring piece 303b-2 and a pressure block 303b-3. Specifically, the floating block 303b-1 has a certain buoyancy, floats on the water surface, and is arranged on the top of the pressing block 303b-3. The pressing block 303b-3 has a certain folding angle, and the elastic piece 303b-2 is arranged on the pressing block 303b-3. The angled end and its end are in contact with the outer surface of the damping rotation sleeve 301c. The lower end of the pressing block 303b-3 is set in the transparent slot 301c-2, and the extended portion of the upper end is connected to the floating block 303b-1. Further, the elastic piece 303b-2 is also provided with a limit hole 303b-5, the latch 303a-2 can be inserted into the limit hole 303b-5 to complete locking, and the pressure block 303b-3 is located in the part of the transparent slot 301c-2. A locking protrusion 303b-4 is provided on the inner side, and the locking protrusion 303b-4 conflicts with the outer protrusion 301b-2 to achieve locking. The corner end of the pressing block 303b-3 is also provided with a shaft 303b-31, and its two ends are Insert into the shaft hole 301c-21 to realize the shaft rotation of the pressing block 303b-3 in the transparent slot 301c-2.

The working principle of the wind lock module 303 in this embodiment is as follows: when the water level is in a normal state, that is, the buoyancy of the floating block 303b-1 is equal to its gravity, and it is just floating on the water surface, and the pressure block 303b-3 is just in the transparent groove. In the opening 301c-2, the pressure between the locking protrusion 303b-4 and the outer protrusion 301b-2 meets the locking condition. At this time, it is in the locked state, and the length of the measured roll cloth 401 is stable. When the water level rises, the buoyancy force on the floating block 303b-1 will increase, causing the floating block 303b-1 to rise. At this time, the pressure block 303b-3 will be driven to rotate, and the lower half of the corner end of the pressure block 303b-3 will rotate. When it tilts upward, the pressure between the locking protrusion 303b-4 and the outer protrusion 301b-2 is reduced. At this time, it is in an unlocked state, and the damping rotating sleeve 301c can rotate. The length of the rolled cloth 401 is measured by being rolled around the damping rotating shaft 301a. The inner part is pulled out and becomes longer to realize the adaptation to the rising water level. During this process, if strong wind is encountered, the wind deflection plate 303a is blown and deflected in the direction of the wind. At this time, the latch 303a-2 will Insert into the limiting hole 303b-5 to prevent the upward movement of the floating block 303b-1 and lock it, so that the damping rotating sleeve 301c cannot rotate, thus completing the locking of the damping module 301 in strong wind. Based on the above, it is easy to find that when the water level drops, you only need to adjust the lifting module 302 to control the relationship between the floating block 303b-1 and the water surface, that is, the size of the buoyancy force on the floating block 303b-1. By the same token, The damping module 301 can be locked and unlocked. It should be noted here that the change in the length of the roll cloth 401 is measured in conjunction with the synchronous rotation of the damping shaft 301a. The change in length of the roll cloth 401 can be measured correspondingly by the number of turns of the damping shaft 301a. Therefore, by measuring the length between the initial measurement roll 401 and the traction chain 101 on the bottom of the water and adding the number of turns the damping shaft 301a rotates due to changes in water level (the number of turns corresponds to the length of the measurement roll 401 extending out), the water level can be obtained. Depth, and the wind lock module 303 ensures that the length of the measured roll cloth 401 does not change in a strong wind environment.

Based on the above-mentioned traction walking system of the water working platform, the traction chain in this system can be directly used as the core component in the underwater trenching, underwater anchoring and linear layout operations of water conservancy projects. The completed traction chain can be directly sunk to the bottom of the water for work. Straight-line layout can be shared in multiple water operations. There is no need to replace operating equipment in each link. Uninterrupted continuous operations not only greatly reduce the disassembly and installation time due to replacement of equipment, improve the continuity of operations, and improve the efficiency of the entire water conservancy project. Efficiency is explained in this embodiment by taking the anti-pollution barrier line applied to Yuqiao Reservoir as an example. Yuqiao Reservoir is located in the east of Jixian County, Tianjin City. The reservoir dam site was built at the outlet of Zhouhe River, the left branch of Jiyun Canal. It is one of the main projects to control Jiyun Canal. The controlled watershed area is 2060km2, and the total storage capacity is 1.559 billion m3. The main rivers entering the reservoir in the upper reaches

They are Linhe, Shahe and Lihe, with an average annual runoff of 506 million m3. After the completion of the Luanhe to Tianjin project in 1983, Yuqiao Reservoir was officially included in the management of the Luanhe to Tianjin project, becoming the only water source in Tianjin. The main functions are flood control and urban water supply, as well as irrigation, power generation, etc. In the Yuqiao Reservoir, the reservoir hub project includes a barrage, water discharge tunnel, spillway, and hydropower station. The barrage is a homogeneous earth dam, that is, the reservoir dam 100 in this embodiment, with a total length of 2222m, a maximum dam height of 24m, a dam top elevation of 28.72m, and a water discharge tunnel (also a power generation tunnel) with a diameter of 5m. The water discharge tunnel here is the base. In the embodiment, water discharge culvert A is used, and the flowing water in the Yuqiao Reservoir can realize operations such as water collection and water discharge in the reservoir. The power station behind the dam is equipped with four tubular flow generating units with a total installed capacity of 5,000 kilowatts. The spillway is an open weir gate with eight holes, with a net width of 80m and a maximum flood discharge capacity of 4138m3/s. The downstream area of the reservoir directly affects nearly 100 low-lying areas in Jixian, Baodi, Ninghe, Yutian, Hangu and other counties (districts). With a population of 10,000 and more than 3 million acres of cultivated land, in 1983 after the completion of the Luan River Diversion Project, Yuqiao Reservoir was officially included in the management of the Luan River Diversion Project and became the only water source in Tianjin. Its main functions are flood control and urban water supply. Irrigation, power generation, etc. Therefore, the water quality of Yuqiao Reservoir directly affects the water supply security of its downstream cities.

The input of nitrogen and phosphorus has caused the water body of Yuqiao Reservoir to become eutrophic. It is generally believed that when the N and P concentrations in the water reach 0.2mg/L and 0.02mg/L respectively, algae will grow in large numbers. The water quality of Yuqiao Reservoir is affected by the upstream water and the environment surrounding the reservoir. In recent years, the annual average value of total nitrogen has been higher than 1.15mg/L, and the total phosphorus has been higher than 0.025mg/L. During the flood season from June to September, a large amount of nitrogen and phosphorus loads are input into the reservoir with runoff, providing a nutritional basis for the growth of cyanobacteria and creating preliminary conditions for cyanobacteria blooms. The rich nutrients also enable some of the dominant populations of aquatic plants in the reservoir, such as waterweeds, to grow in great quantities. Nearly 95,000 m3 of waterweeds are fished out of the water surface of the reservoir every year. Except for the main channel of the Zhouhe River, the growing area of philodendron has basically covered the entire reservoir area. In addition, the morphological characteristics of Yuqiao Reservoir also provide favorable conditions for water eutrophication and the outbreak of cyanobacteria blooms. Due to the small water depth in the north, light radiation can reach relatively deep underwater, resulting in higher water temperature and slow water flow. Whether there is wind or not, it has little effect on improving the flow pattern, so it is more suitable for the reproduction and accumulation of algae. Algae blooms make this area a high-value area for phytoplankton in the reservoir. Affected by multiple conditions, cyanobacteria blooms are easily formed in Yuqiao Reservoir in summer, posing a threat to the safety of urban water supply. But in fact, the occurrence of blue-green algae blooms in Yuqiao Reservoir is not terrible, because naturally growing living blue-green algae will not pollute the water quality. However, if the treatment is not effective, it will accumulate in the waters in front of the dam (downwind), and then die and rot, polluting the water quality. Therefore, it is necessary to make use of the natural characteristics of cyanobacteria drifting and gathering, and with the help of the topography, wind and water flow of the Qiao Reservoir, set up blocking-diversion-algae removal facilities on the path of their drifting and gathering, to effectively enrich and remove cyanobacteria, which can not only prevent the dam from The occurrence of blue-green algae disasters in the front waters can also reduce the base of the blue-green algae population in the entire reservoir area and take away the nutrients contained in it by removing large amounts of blue-green algae, effectively curbing the accumulation of nutrients in the water body and the development of blue-green algae blooms. Although emergency measures have been taken to remove accumulated cyanobacteria in front of the dam, water quality pollution has already formed. The content of cyanobacteria in the water supply is too high, and the pollutants released by the decay and decomposition of cyanobacteria have seriously affected the quality of the water supply.

Therefore, it is necessary to set up an intelligent blocking and defense line at the throat in front of the reservoir dam to block algae blooms and prevent pollution. The traction walking system of the water working platform of the present invention is applied to the construction of the blocking and defense line here, including underwater slotting, underwater Anchoring and straight-line laying operations, in which underwater troughing utilizes the floating platform 200 to walk on the traction assembly 100, connect heavy objects to the bottom of the floating platform 200 and sink them to the bottom of the water, and move the floating platform 200 on the water surface to remove the heavy objects on the water bottom. Dragging back and forth at the bottom of the reservoir can remove the bottom mud along the dragging trajectory, thereby opening a groove corresponding to the traction chain 101 at the bottom of the reservoir. Further, the floating platform 200 is used again to tie the floating body to the traction chain 101. Here, the floating body is tied to the ring of the connecting ring 101a through a nylon rope. The floating body is placed on the floating platform 200. As the floating platform 200 moves, it gradually The floating body is tied to the traction chain 101. When the binding is completed, the floating platform 200 returns. It should be noted here that when the traction chain 101 needs to sink to the bottom, one end of the traction chain 101 is connected to the fixed component 102 on the shore and the other end is connected to the anchor boat. , so the length of the traction chain 101 can gradually become longer as the anchor ship end is released. Under normal circumstances, when using the water working platform, in order to increase its stability, the traction chain 101 at the anchor ship end is fixed to the fixed component 102, so in this state The traction chain 101 below is connected to the fixed components 102 on both sides of the water respectively, so that when the floating platform 200 returns, the nylon rope connecting the traction chain 101 and the floating body is gradually cut off. As the traction chain 101 is released at the anchor ship end, due to the The effect of gravity realizes the gradual sinking of the traction chain 101 to the bottom, completing the straight line sinking and laying operation. The underwater anchoring operation is synchronized with the bottom sinking operation of the traction chain 101. When the floating body is bound to the traction chain 101, the sewn gabion bag is also tied to the traction chain 101. When the nylon rope on the floating body is cut, The gabion bag is connected to the traction chain 101, and along with the traction chain 101, it sinks to the bottom of the reservoir to complete the anchoring operation.

It should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solution of the present invention can be carried out. Modifications or equivalent substitutions without departing from the spirit and scope of the technical solution of the present invention shall be included in the scope of the claims of the present invention.
