Description

Technical Field

[0001] This utility model relates to the field of thermal power plant construction technology, specifically a dewatering structure for thermal power plant construction. Background Technology

[0002] A thermal power plant, or coal-fired power plant for short, is a factory that uses coal, oil, or natural gas as fuel to produce electricity. Its basic production process is as follows: fuel is burned in a boiler to heat water to make steam, which converts the chemical energy of the fuel into heat energy. The steam pressure drives the turbine to rotate, converting the heat energy into mechanical energy. Then the turbine drives the generator to rotate, converting the mechanical energy into electrical energy.

[0003] Application number CN201922211429.6 discloses a dewatering structure for the construction of a thermal power plant, including a foundation pit and other structures. This utility model utilizes an upper filter screen to filter large particles of sand and gravel from wastewater and protect the upper port of the dewatering well, ensuring construction safety. The lower filter screen further filters finer particles of sand and gravel from the wastewater, preventing blockage of the pump. A sludge collection cylinder collects sludge, allowing for easy and efficient cleaning of the inner cavity of the aluminum pipe when it is lifted by external lifting equipment. However, in practical use, if the sludge collection cylinder is smaller than the size of the dewatering well, the sludge distributed around the cylinder will quickly fill the space between the well wall and the cylinder under the suction force of the pump, affecting pumping operations and potentially damaging the pump. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A dewatering structure for construction of a thermal power plant includes a dewatering mechanism, an anti-blocking mechanism, and a netting mechanism. The dewatering mechanism includes a water pump, a cap fitted onto the outside of the pump's intake end, a U-shaped cylinder screwed onto the cap, and multiple water inlets on the U-shaped cylinder. The anti-blocking mechanism includes a mesh fitted onto the outside of the U-shaped cylinder and multiple water-swellable rubbers connected to the outer edge of the mesh. The netting mechanism includes multiple cylinders surrounding the outside of the U-shaped cylinder and a steel plate connecting the water-swellable rubbers and the movable ends of the cylinders.

[0007] By adopting the above technical solution, after the ⊥-shaped cylinder is submerged in the well water, multiple cylinders use steel plates to make the water-swellable rubber adhere to the well wall. Then, the mesh is stretched to cover the entire water surface inside the well. Here, the water-swellable rubber absorbs water and expands, increasing its volume by 200%-600%. The water-swellable rubber then fills the gap between the well wall and the mesh, effectively preventing silt from passing through the mesh into the ⊥-shaped cylinder, effectively ensuring pumping efficiency and avoiding damage to the water pump.

[0008] In a preferred embodiment, this utility model can be further configured as follows: multiple water inlets are equally spaced and arranged in a ring, with the water inlets located at the top of the mesh and communicating with the interior of the ⊥-shaped cylinder.

[0009] In a preferred embodiment, this invention can be further configured such that multiple water-swellable rubber rings are arranged on the outside of the ⊥-shaped cylinder and are bonded together in pairs.

[0010] In a preferred embodiment, this invention can be further configured as follows: multiple cylinders connected in series, wherein the cylinders are electrically connected to an external power supply.

[0011] In a preferred embodiment, the present invention can be further configured such that the outer surface of the steel plate is coated with a waterproof coating.

[0012] In a preferred embodiment, the present invention can be further configured such that a guide rod is slidably connected between two adjacent water-swellable rubbers, and both ends of the guide rod are T-shaped.

[0013] In a preferred embodiment, the present invention can be further configured such that: a waterproof sleeve is fitted onto the outer side of the cylinder, and the waterproof sleeve is fixedly connected to the outer edge of the U-shaped cylinder.

[0014] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0015] 1. In this utility model, after the ⊥-shaped cylinder is submerged in well water, multiple cylinders use steel plates to make the water-swellable rubber adhere to the well wall. Then, the mesh is stretched to cover the entire water surface inside the well. Here, the water-swellable rubber absorbs water and expands, increasing its volume by 200%-600%. The water-swellable rubber then fills the gap between the well wall and the mesh, effectively preventing silt from passing through the mesh into the ⊥-shaped cylinder, effectively ensuring pumping efficiency and avoiding damage to the water pump.

[0016] 2. In this utility model, when the water-swellable rubber absorbs water and expands, the multiple water-swellable rubbers with increased spacing will extend along the direction of the guide rod. The guide rod allows two adjacent water-swellable rubbers to continue to adhere, and then guides the water-swellable rubbers to fill the gap between the mesh and the well wall, ensuring that the well water inside the well is completely covered.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0028] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0029] The following describes, with reference to the accompanying drawings, some embodiments of a dewatering structure for thermal power plant construction provided by this utility model.

[0030] Example 1:

[0031] Combination Figure 1-5 As shown, the present invention provides a dewatering structure for the construction of a thermal power plant, including a dewatering mechanism 100, an anti-blocking mechanism 200, and a netting mechanism 300. The dewatering mechanism 100 includes a water pump 110, a cap 120 sleeved on the outside of the pumping end of the water pump 110, a U-shaped cylinder 130 screwed to the cap 120, and multiple water inlets opened on the U-shaped cylinder 130.

[0032] Anti-blocking mechanism 200, the anti-blocking mechanism 200 includes a mesh 210 sleeved on the outside of the ⊥-shaped cylinder 130, and a plurality of water-swellable rubbers 220 connected to the outer edge of the mesh 210;

[0033] The net pulling mechanism 300 includes a plurality of cylinders 310 surrounding the outside of the ⊥-shaped cylinder 130, and a steel plate 320 connecting the water-swellable rubber 220 and the movable end of the cylinders 310.

[0034] Furthermore, multiple water inlets are arranged in a ring at equal intervals. The water inlets are located at the top of the mesh 210 and are connected to the interior of the ⊥-shaped cylinder 130. The layout design of the water inlets allows the water in the well to quickly fill the ⊥-shaped cylinder 130. The height design of the water inlets effectively prevents impurities such as sludge from entering the ⊥-shaped cylinder 130.

[0035] Furthermore, multiple water-swellable rubbers 220 are arranged in a ring around the outside of the ⊥-shaped cylinder 130 and are bonded together in pairs. This layout design provides conditions for complete adhesion to the inner wall of the well and prevents silt from surging up.

[0036] Furthermore, multiple cylinders 310 are connected in series, and each cylinder 310 is electrically connected to an external power supply. This structural design facilitates operator control of the cylinders 310.

[0037] Furthermore, a waterproof sleeve is fitted around the outside of the cylinder 310. The waterproof sleeve is fixed to the outer edge of the ⊥-shaped cylinder 130. The waterproof sleeve serves to protect the cylinder 310 and prevent it from being corroded by water.

[0038] Example 2:

[0039] Combination Figure 2 and Figure 5 As shown, based on Embodiment 1, the outer surface of the steel plate 320 is coated with a waterproof coating, which can ensure the service life of the steel plate 320.

[0040] Example 3:

[0041] Combination Figure 5 As shown, in the above embodiment, a guide rod 400 is slidably connected between two adjacent water-swellable rubbers 220. Both ends of the guide rod 400 are T-shaped. The guide rod 400 can guide the deformation direction of the water-swellable rubbers 220, so that the water-swellable rubbers 220 can accurately fill the gap between the well wall and the mesh 210 after absorbing water and expanding.

[0042] The working principle and usage process of this utility model are as follows: When this device is put into actual use, the water pump 110 is placed on one side of the well. After the cap 120 is connected to the U-shaped cylinder 130, the U-shaped cylinder 130 is submerged in the water. During the sinking process of the U-shaped cylinder 130, multiple cylinders 310 use steel plates 320 to make the water-swellable rubber 220 adhere to the well wall. Then the mesh 210 is stretched to cover the entire water surface in the well. Here, the water-swellable rubber 220 absorbs water and expands, increasing its volume by 200%-600%. Under the influence of the guide rod 400, two adjacent water-swellable rubbers 220 remain in a tight state, and also fill the gap between the well wall and the mesh 210, effectively preventing silt from passing through the mesh 210 into the U-shaped cylinder 130, effectively ensuring the pumping efficiency and avoiding damage to the water pump 110.

[0043] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
