Description

Technical Field

[0001] The invention belongs to the technical field of water conservancy engineering equipment, and in particular relates to a pressure water tank for a water conservancy engineering flood drainage station. Background Art

[0002] In the operation of water conservancy project drainage stations, pressure water tanks play a vital role. However, existing pressure water tanks for water conservancy project drainage stations have many limitations in practical applications. On the one hand, the internal structure design of some pressure water tanks is not reasonable enough, and eddies and turbulence are easily generated when water flows in the water tank, resulting in low water flow efficiency and affecting the drainage effect. For example, the water cannot flow evenly through the water tank, which makes drainage in some areas poor, prolongs the drainage time, and cannot effectively remove the accumulated water in time when floods occur, bringing greater safety hazards to the surrounding areas. On the other hand, it is difficult to clean the silt at the bottom of the existing pressure water tank. As time goes by, the silt gradually accumulates at the bottom of the water tank, which not only occupies the effective volume of the water tank and reduces the water storage capacity of the water tank, but also may cause corrosion to the inner wall of the water tank, shorten the service life of the water tank, and increase maintenance costs.

[0003] In order to solve the above problems, it is necessary to develop a new type of pressure water tank for water conservancy project drainage stations. This pressure water tank should optimize the internal structure, reduce the vortex and turbulence of the water flow by setting reasonable spoilers and adjustable baffles, improve the water flow efficiency, and ensure the efficient and stable drainage process. At the same time, it should be equipped with a special cleaning mechanism that can automatically clean the silt at the bottom of the water tank, avoid the adverse effects of silt accumulation, reduce maintenance costs, and extend the service life of the water tank, so as to better meet the actual needs of water conservancy project drainage stations and ensure flood control safety in surrounding areas. Summary of the invention

[0004] The purpose of the present invention is to provide a pressure water tank for a drainage station of a water conservancy project, aiming to solve the problems in the prior art that, first, water cannot flow evenly through the water tank, resulting in poor drainage, prolonged drainage time, and failure to drain water in time during floods, threatening the safety of surrounding areas; second, it is difficult to clean the silt at the bottom, and the accumulation of silt will occupy the volume of the water tank, reduce the water storage capacity, corrode the inner wall, shorten the life of the water tank and increase the maintenance cost.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0012] A nut, wherein the nut is threadedly connected to the circumferential surface of the screw rod;

[0013] A push plate, the push plate being fixedly connected to the circumferential surface of the nut;

[0014] The inclined block is provided with two inclined blocks, and the two inclined blocks are respectively fixedly connected to the two ends of the nut.

[0015] As a preferred solution of the present invention, the bottom end of the pressure water tank body is fixedly connected with four support seats, the adjacent ends of the four support seats are respectively fixedly connected with fixing plates, and both ends of the pressure water tank body are fixedly connected with two end connecting plates.

[0016] As a preferred solution of the present invention, valves are fixedly connected to the circumferential inner walls of the drain pipe and the water inlet pipe respectively.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In this solution, the first motor drives the connecting rod and the gear to rotate, and the gear meshes with the rack belt to drive the partition to rotate, thereby changing the water flow path and making the water flow evenly distributed in the water tank.

When the nut moves to one end of the screw, the second motor reverses, driving the nut and the push plate to move in the opposite direction, and continuously cleaning the sludge through reciprocating motion. Moreover, the cleaning mechanism can be automatically controlled by the second motor to achieve scheduled or on-demand cleaning, reduce manual intervention, and improve the operating efficiency of the drainage station. This not only avoids the impact of sludge accumulation on the volume and water storage capacity of the water tank, but also prevents the sludge from corroding the inner wall of the water tank, prolongs the service life of the water tank, and reduces maintenance costs. For example, after long-term use monitoring, after adopting the cleaning mechanism of the present invention, the maintenance times of the water tank are reduced by [X] times per year, and the service life is extended by [X] years, saving a lot of maintenance funds for water conservancy projects.

[0031] The cleaning mechanism is arranged in the pressure water tank body 1 and is used to clean the silt on the inner wall at the bottom of the pressure water tank body 1 .

[0032] In a specific embodiment of the present invention, the pressure water tank body 1 serves as the main structure of the entire device, and is used to contain water and silt, withstand internal water pressure, and support the installation of other components.

[0033] The limiting grooves 19 are provided on the inner walls of both sides of the pressure water tank body, and are used to fix and limit the connecting rod 11, so as to ensure that the connecting rod remains stable when rotating.

[0034] The positioning holes are located on the front and rear inner walls of the limiting groove and are used to install the connecting rod 11 so that it can rotate, thereby realizing the rotation of the partition 18.

[0035] The connecting rod 11 is connected to the pressure water tank body through the positioning hole, supports the partition 18 and drives it to rotate, and adjusts the direction and flow rate of water flow.

[0036] The partition 18 is fixed on the connecting rod 11, and changes the water flow path by rotation, thereby helping to adjust the water flow distribution in the water tank and enhancing the drainage effect.

[0037] The water inlet pipe 7 and the drain pipe 6 are used to introduce water into the pressure water tank, and the drain pipe is used to discharge water, thereby realizing the inlet and outlet control of water flow.

[0038] The flange 8 is fixed on the circumferential surface of the water inlet pipe and the drain pipe to connect the pipes, ensure the sealing and stability, and prevent water leakage.

[0039] The first motor 3 provides power to drive the connecting rod 11 and the gear 12 to rotate, thereby driving the partition 18 to rotate and adjust the water flow.

[0040] The gear 12 is fixed on the connecting rod 11 and meshes with the rack belt 10 to transmit the rotational motion of the motor to the connecting rod to realize the rotation of the partition.

[0041] The rack belt 10 meshes with the gear 12 to transmit power and ensure the synchronous movement of the gear and the connecting rod, thereby controlling the rotation of the partition.

[0042] The spoiler 20 is fixed to the front and rear inner walls of the pressure water tank body to change the direction of water flow, reduce eddy currents and turbulence, and improve water flow efficiency.

[0043] The cleaning mechanism is arranged in the pressure water tank body and is used to clean the sludge at the bottom to prevent the sludge accumulation from affecting the normal operation of the water tank and to keep the inside of the water tank clean and running efficiently.

[0044] For details, please refer to Figure 1-Figure 4 , cleanup agencies include:

[0045] The screw rod 15 is rotatably connected to the inner walls of both sides of the pressure water tank body 1, and one end of the screw rod 15 movably penetrates one side inner wall of the pressure water tank body 1 and is rotatably connected to one side end of the pressure water tank body 1;

[0046] A second motor 17, the second motor 17 is fixedly connected to one side end of the pressure water tank body 1, and an output end of the second motor 17 is fixedly connected to one end of the screw rod 15;

[0047] A nut 16, wherein the nut 16 is threadedly connected to the circumferential surface of the screw rod 15;

[0048] A push plate 13, the push plate 13 is fixedly connected to the circumferential surface of the nut 16;

[0049] The inclined blocks 14 are provided with two inclined blocks 14 , and the two inclined blocks 14 are fixedly connected to the two ends of the nut 16 respectively.

[0050] In this embodiment, the screw rod 15 serves as the core transmission component of the cleaning mechanism. The screw rod converts the power of the second motor 17 into linear motion through rotational motion, driving the nut 16 and the push plate 13 to move, thereby realizing the cleaning function.

[0051] The second motor 17 provides power to drive the screw rod 15 to rotate, thereby driving the nut 16 and the push plate 13 to move, thereby realizing the operation of the cleaning mechanism.

[0052] The nut 16 is threadedly connected to the screw rod 15, and the rotational motion of the screw rod is converted into a linear motion, so as to drive the push plate 13 and the inclined block 14 to move, and push the sludge to move in a specified direction.

[0053] The push plate 13 is fixed on the nut 16 and moves with the linear motion of the nut, directly contacts and pushes the sludge, and collects the sludge to a designated position for cleaning.

[0054] The inclined block 14 is fixed at both ends of the nut 16 to assist the push plate 13 in cleaning the sludge. Its inclined surface design can better guide the sludge flow and prevent the sludge from accumulating on both sides of the push plate. After the second motor 17 is started, its output end drives the screw 15 to rotate.

[0055] Since the screw rod 15 and the nut 16 are threadedly connected, the rotational motion of the screw rod is converted into the linear motion of the nut 16 .

[0056] When the sludge cleaning nut 16 moves on the screw rod 15, it drives the push plate 13 and the inclined block 14 to move together.

[0057] The push plate 13 directly contacts the mud on the inner wall of the bottom of the pressure water tank and pushes it forward.

[0058] The inclined surface design of the inclined block 14 helps guide the sludge to flow in a specified direction, thereby preventing the sludge from accumulating on both sides of the push plate.

[0059] When the nut 16 moves to one end of the screw rod 15, the second motor 17 reverses and drives the nut 16 and the push plate 13 to move in opposite directions.

[0060] Through reciprocating motion, the cleaning mechanism can continuously push the sludge to the mud discharge port or concentrated area of ​​the pressure water tank for subsequent cleaning.

[0061] The automatic cleaning mechanism can realize scheduled or on-demand cleaning through the automatic control of the second motor 17, reduce manual intervention, and improve the operation efficiency of the drainage station.

[0062] For details, please refer to Figure 1-Figure 3 The bottom end of the pressure water tank body 1 is fixedly connected with four support seats 4, and the adjacent ends of the four support seats 4 are fixedly connected with fixing plates 5 respectively. Both ends of the pressure water tank body 1 are fixedly connected with two end connecting plates 2.

[0063] In this embodiment: the support seat 4 is fixed to the bottom end of the pressure water tank body 1, and is used to support the weight of the entire pressure water tank to ensure its stability and balance. The design of the support seat can disperse the weight of the pressure water tank and prevent the bottom from being deformed or damaged due to uneven force.

[0064] The fixing plate 5 is connected to the adjacent ends of the four support seats 4 to enhance the connection strength between the support seats and further improve the overall stability of the pressure water tank. The fixing plate can also prevent the support seats from being displaced or deformed when subjected to force.

[0065] The two end connecting plates 2 are fixed at the two ends of the pressure water tank body 1 to strengthen the structural strength of the pressure water tank and prevent the water tank from deforming when it is subjected to internal water pressure. In addition, the connecting plates can also be used as the installation basis for other external equipment such as pipelines or motors.

[0066] For details, please refer to Figure 2 Valves 9 are fixedly connected to the circumferential inner walls of the drain pipe 6 and the water inlet pipe 7 respectively.

[0067] In this embodiment: valve 9 is installed on the inner wall of the circumference of the drain pipe 6 and the water inlet pipe 7 to control the on-off and flow rate of the water flow. By adjusting the valve, accurate control of water inlet and outlet can be achieved to ensure efficient operation of the pressure water tank in the drainage operation.

[0068] The working principle and use process of the present invention are as follows: water first enters the pressure water tank body 1 through the water inlet pipe 7, and the valve 9 on the water inlet pipe 7 controls the flow rate and on-off of the water flow; then the first motor 3 is started to drive the connecting rod 11 and the gear 12 to rotate, and the gear 12 is engaged with the rack belt 10 to drive the partition 18 to rotate, thereby changing the water flow path and making the water flow evenly distributed in the water tank; at the same time, when the water flows in the water tank, the spoiler 20 changes the direction of the water flow, reduces eddy currents and turbulence, and improves the water flow efficiency; finally, the regulated water flow is discharged through the drain pipe 6, and the valve 9 on the drain pipe 6 controls the drainage flow. The operation process for solving the bottom sludge cleaning problem is as follows: when the sludge at the bottom of the pressure water tank accumulates to a certain extent, the second motor 17 is started to drive the screw rod 15 to rotate, and the rotational motion of the screw rod 15 is converted into the linear motion of the nut 16 through the threaded connection, and the nut 16 drives the push plate 13 and the inclined block 14 to move along the screw rod 15, and the push plate 13 directly contacts and pushes the sludge, and the inclined block 14 guides the sludge to flow in a specified direction to avoid its accumulation on both sides of the push plate; the sludge is concentrated at the mud discharge port or concentrated area for subsequent cleaning; when the nut 16 moves to one end of the screw rod 15, the second motor 17 reverses, driving the nut 16 and the push plate 13 to move in the opposite direction, and continuously cleaning the sludge through reciprocating motion; and the cleaning mechanism is automatically controlled by the second motor 17, and can be cleaned regularly or on demand, reducing manual intervention and improving the operation efficiency of the drainage station. In summary, the present invention ensures that water flows evenly through the water tank through the coordination of the baffle 18 and the spoiler 20, and utilizes the screw 15, nut 16, push plate 13 and inclined block 14 of the cleaning mechanism to automatically clean the silt at the bottom of the water tank to avoid affecting the normal operation of the water tank.
