[0002] Hydropower generation has the characteristics of resource recycling, clean and environmental protection, and extensive resources. The available resources include large rivers, small rivers, streams, tailwater channels of power stations, etc. Traditional flowing water power generation systems mostly place equipment such as water wheels, bearing chambers and / or generator sets in the water body through floating bodies. However, flowing water has the characteristics of water flow velocity, flow rate, and time-varying water level, and turbulence often occurs, which makes the force on the floating body in the water very complicated. The equipment will float with the floating body in the water body, making it difficult to maintain balance. When the water level drops, there is a risk of hitting the bottom, causing the equipment to tilt or be damaged. When the water flow rate is too fast, the equipment is easily washed away by the water flow and accidents occur. It is difficult to ensure the safe, stable and efficient operation of the power generation system. Summary of the invention

DETAILED DESCRIPTION

[0025] See also Figure 1 and Figure 2The adjustable buoyancy and anti-bottoming traction support of the present invention is mainly used to support power generation equipment in the water body during water power generation, and can also be used to support and support other water equipment, including a support body 1, a device platform 2 is horizontally fixedly installed on the top surface of the support body, and the device platform is used to install equipment such as a water wheel, a bearing chamber 3 and / or a generator set, and the support body is used to support the device platform. A balancing and regulating water tank 4 is provided at the bottom of the support body, and the support body is provided with a plurality of support supports extending downward, and the plurality of support supports are evenly distributed on the support body. The setting of the balancing and regulating water tank can provide buoyancy for the support body, so that the support body floats in the water body. When a certain amount of water is injected into the balancing and regulating water tank, when the water surface of the water body fluctuates greatly or turbulence occurs, the water in the balancing and regulating water tank has fluidity, and will also fluctuate accordingly, offsetting the impact force of the traction support from the water body, so that the traction support remains balanced, thereby maintaining the stability (or level) of the device platform and the equipment installed thereon, and ensuring the safe, stable and efficient operation of the power generation system. In addition, by adjusting the water injection amount in the balance regulating water tank, the draft depth of the traction bracket in the water body can also be adjusted to meet the working needs of the power generation system in different water environments. The support of the bracket can be supported on the bottom of the water when the water level of the water body drops, avoiding the bracket body from touching the bottom and causing tilting or damage.

[0026] The balancing and adjusting water tank is preferably conformal to the bottom of the bracket body, that is, the cross-section of the balancing and adjusting water tank is the same shape and size as the cross-section of the bottom of the bracket body, and the corresponding side edges are aligned and installed at the bottom of the bracket body. The balancing and adjusting water tank covers the cross-section of the bottom of the bracket body so that when the traction bracket is placed in the water body, the buoyancy of the bracket body is balanced.

[0027] The balancing and regulating water tank is provided with a water inlet pipe 5, the water inlet of which is located on the top surface of the bracket body, for injecting water into the balancing and regulating water tank. The number of the water inlet pipes can be several, for example three or four, to improve the water injection efficiency, and the several water inlet pipes are evenly distributed on the bracket body.

[0028] The bottom wall of the balancing and regulating water tank may be provided with a drain port for draining the balancing and regulating water tank, and the drain port is provided with a drain valve or a drain port cover. Alternatively, the balancing and regulating water tank is provided with a drain pipe, and the drain pipe is connected to a drain pump for pumping water out of the balancing and regulating water tank.

[0029] A water pump may be provided on the bracket body, the water outlet of the water pump is connected to the water inlet of the water inlet pipe, and the water inlet of the water pump is connected to a water pump hose. When the traction bracket is placed in the water body, water can be pumped into the balancing and regulating water tank through the water pump.

[0030] The support bracket preferably includes a vertical support column 6 and a support foot 7 provided at the bottom end of the support column. The bottom surface of the support foot is a plane, which helps to provide stable support. The support foot is rotatably connected to the support column (for example, connected through a matching shaft and bearing). With such a configuration, when the support foot contacts and supports the bottom of the water, it can flexibly rotate according to the flatness of the bottom of the water, adapt to the force of landing, and ensure the horizontality of the support body.

[0031] The number of the bracket supports can be two. When the power generation equipment installed on the traction bracket of different power generation equipment is appropriately connected (for example, the waterwheel axle and the bearing chamber of the waterwheel are appropriately connected), a stable structure with four-leg supports or multiple-leg supports can be achieved.

[0032] The support column is preferably provided with an extension length adjustment mechanism extending downward from the bottom surface of the bracket body, so that the length of the support column extending downward from the bottom surface of the bracket body can be flexibly adjusted according to actual work needs (such as the height requirement of the power generation equipment installed on the equipment platform) and / or the actual situation of the bottom undulation.

[0033] The extension length adjustment mechanism is preferably a trapezoidal screw 8, which has a simple structure, strong load-bearing capacity and a self-locking function. The trapezoidal screw is vertically arranged, and its nut is fixedly connected to the bracket body, and the bottom end of its screw is fixedly connected to the top end of the support column. The top end of the screw of the trapezoidal screw extends upward from the top surface of the bracket body, which is convenient for rotation operation. By rotating the screw, the screw moves vertically relative to the nut, driving the support column to move vertically, and adjusting the length of the bottom surface of the bracket body extending downward. The screw can be provided with a motor to drive its rotation, which is convenient for rotation operation, and the motor can be arranged on the top surface of the bracket body.

[0034] The bracket body may be provided with a vertical bracket support mounting sleeve that passes through the bracket body up and down, the bracket support mounting sleeve is tubular, the bracket support is coaxially mounted in the bracket support mounting sleeve, the nut of the trapezoidal screw is fixedly connected to the bracket support mounting sleeve, and a spacing is left between the screw of the trapezoidal screw and the support column and the inner wall of the bracket support mounting sleeve.

[0035] The top surface of the bracket body may be provided with a screw locking mechanism for the trapezoidal lead screw. When the screw does not need to be rotated, the screw can be locked by the screw locking mechanism to prevent it from rotating accidentally. The screw locking mechanism may be a horizontal sliding plate provided on the top surface of the bracket body. The end of the horizontal sliding plate facing the screw is provided with a notch that matches the trapezoidal teeth of the screw. The horizontal sliding plate and the top surface of the bracket body are slidably matched (for example, through the cooperation of a slide rail and a slide groove, and a suitable sliding locking device, such as a top screw). When the length of the support column extending downward from the bracket body is adjusted, the notch on the horizontal sliding plate can be inserted between adjacent trapezoidal teeth of the screw by sliding the horizontal sliding plate to achieve locking of the screw.

[0036] The extension length adjustment mechanism may also adopt other mechanisms in the prior art that can convert rotary motion into linear motion, such as a ball screw.

[0037] The support body is preferably a frame structure, which can ensure its structural strength and reduce weight, and can be formed by appropriately connecting steel pipes, steel columns or steel bars. Support ribs (or reinforcing ribs) can be provided in the support body to improve the overall structural strength.

[0038] The bottom surface of the bracket body is preferably rectangular, and the top is high on the left and right sides and low in the middle, that is, the middle part of the top surface of the bracket body is low, and the left and right sides are high, and the equipment platform is installed on a relatively low plane in the middle of the top surface of the bracket body.

[0039] See also Figure 3 The rear side of the bottom surface of the support body is an inclined surface inclined toward the rear side surface of the support body, or the front side of the bottom surface of the support body is an inclined surface inclined toward the front side surface of the support body. When the water level of the water body drops, when the traction support is supported on the bottom of the water by the support legs, the bottom surface of the support body can adapt to the slope of the revetment or slope to avoid touching the bottom. The slope of the inclined surface can be designed according to the actual underwater conditions of the application of the traction support when manufacturing the support body.

[0040] A traction plate 9 is preferably provided on at least one side of the bracket body, through which the traction bracket can be fixedly connected to a fixed object (such as a pile) on the shore or in the water body, which can not only prevent the traction bracket from being washed away by the water flow, but also keep the position of the traction bracket in the water body unchanged, and can also maintain the stability and horizontality of the traction bracket to a certain extent.

[0041] The top surface of the bracket body is preferably provided with a lifting ear plate 10 for mobile lifting of the traction bracket. The number of the lifting ear plates is several (for example, four), and the several lifting ear plates are evenly distributed on the top surface of the bracket body.

[0042] A better operating method of the traction bracket when in use is: first hoist it into the water body to float, then adjust the length of the bracket support extending out of the bottom surface of the bracket body according to the actual situation of the bottom of the water to prevent the traction bracket from touching the bottom when the water level drops, and then fill water into the balance adjustment water tank to adjust the draft of the traction bracket to meet the installation requirements of the power generation system and connect or assemble the power generation system (for example, connect the waterwheel axle and bearing chamber of the waterwheel), and fix it to the shore or fixed objects in the water body through the traction plate.

[0043] Unless otherwise specified or one preferred or optional technical means is a further limitation of another technical means, all preferred and optional technical means disclosed in the present invention can be arbitrarily combined to form several different technical solutions.
