Description

Technical Field

[0001] The utility model relates to the technical field of thermal power plants, in particular to a high-strength mounting seat for an accumulator in a thermal power plant. Background Art

[0002] The thermal power plant industry has long been interested in potential accumulator bodies based on first-order phase changes (e.g., the transition from solid to liquid and vice versa), because, on the one hand, a reversible phase change occurs at a constant temperature, and on the other hand, the potential enthalpy (melting or crystallization enthalpy) underlying the transition can take on relatively high values, such that materials can thermally and, in particular, enthalpically stabilize specific processes and / or temperature levels for a longer period of time, particularly advantageously in power plants, by bringing the phase change material, which is often hermetically encapsulated, into contact with a working medium such as water and / or steam, the working medium can be kept at a constant temperature for a longer period of time, i.e., when the temperature of the working medium drops below a specified threshold value (phase change temperature of the storage material), if the phase change material is, for example, in liquid form and is cooled by the working medium whose temperature is falling, a defined phase change to a solid state occurs, wherein the crystallization enthalpy is released and the temperature remains constant until complete solidification, in which process the working medium undergoes enthalpy and thermal stabilization under the premise of good thermal contact, in this way, an effective thermal intermediate storage can be achieved.

[0003] The traditional accumulator body group consists of a large bracket that loads the entire module. The bottom of the large bracket is provided with a supporting angle or a pre-buried shaft embedded in the ground. The weight of multiple accumulator body groups stacked together is heavy, which requires the base of the large bracket to have a good load-bearing capacity, otherwise it will cause the entire large bracket to collapse, and it is also easy to cause the back frame of the accumulator body to deform, which cannot play a good load-bearing effect. There are safety hazards during operation. Therefore, we proposed a high-strength mounting base for accumulators in thermal power plants to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of the utility model is to provide a high-strength mounting base for an accumulator in a thermal power plant, so as to solve the problem proposed in the above-mentioned background technology that a traditional accumulator body group on the market currently consists of a large bracket that loads the entire module, and a supporting angle or a pre-buried shaft pre-buried in the ground is provided at the bottom of the large bracket. The weight of multiple accumulator body groups stacked together is heavy, which requires the base of the large bracket to have a good load-bearing capacity, otherwise the entire large bracket will collapse, and the back frame of the accumulator body will easily deform, which will not have a good load-bearing effect and will pose a safety hazard during operation.

[0005] To achieve the above object, the utility model provides the following technical solution: a high-strength mounting base for an accumulator in a thermal power plant, comprising a frame, an accumulator body is fixed to the front side of the frame by a clamp, a large bracket is installed at the lower end of the frame, an oil return pipe is passed through the interior of the large bracket, and an oblique support shaft is connected to the inner wall of the large bracket;

[0006] The four corners of the lower side of the large bracket are all equipped with embedded shafts, the outer side of the lower section of the embedded shaft is connected with a positioning piece, and the lower end of the embedded shaft is provided with a conical groove;

[0007] Support components for reinforcing the accumulator mounting seat are arranged on both the front and rear sides of the frame.

[0008] Preferably, the support assembly includes a base plate hinged at the lower ends of the front and rear sides of the frame, a slider is slidably connected inside the base plate, a support rod is hinged on the upper side of the slider, a fixed block is hinged on the upper end of the support rod, the fixed block and the frame are fixed by bolts, and the slider and the base plate are fixed by bolts.

[0009] Preferably, the conical grooves are evenly spaced and distributed on the outside of the embedded shaft. The conical grooves are located below the positioning piece. In this design, after the embedded shaft is driven in, a portion of concrete enters the groove, and the conical grooves of this shape can be stuck to prevent the embedded shaft from moving up.

[0010] Preferably, the cross-sectional surface of the large bracket is a symmetrically distributed side "U"-shaped structure, and the inner wall of the large bracket is an arc-shaped support. This design has a good supporting and supporting effect in the longitudinal plane.

[0011] Preferably, the arcuate supporting surface of the large bracket is connected to the oil return pipe through an oblique supporting shaft, and oblique supporting shafts are installed at the four corners of the arcuate supporting surface of the large bracket. This design allows every two adjacent oblique supporting shafts to form multiple triangles, thereby improving the supporting strength.

[0012] Preferably, the positioning piece is a conical structure, and the outer diameter of the positioning piece decreases from top to bottom. The outer diameter of the top surface of the positioning piece is greater than or equal to 5 cm. This design will not affect the downward extension of the embedded shaft when the embedded shaft is driven in. After the embedded shaft is driven in, the positioning piece is left inside, which can prevent the embedded shaft from moving upward, thereby maintaining the installation position of the large bracket and ensuring a firm installation.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) The high-strength mounting base of the thermal power plant accumulator increases the structural thickness on the basis of the traditional large bracket, making the structural strength of the large bracket higher and less prone to deformation, and there is enough space to install the return oil pipe, and multiple oblique support shafts are added on the basis of the large bracket to ensure that the upper and lower surfaces of the large bracket will not be deformed due to pressure;

[0015] (2) The high-strength mounting base of the thermal power plant accumulator changes the traditional floor-mounted installation method and replaces the simple embedded steel bars with embedded shafts with positioning parts. This way, the embedded shafts will not be displaced after being installed, and it is even less likely that the installation will become loose, which improves the safety of the operation. Several grooves are opened on the outer wall of the embedded shafts to increase connectivity and friction, so that the embedded shafts can maintain the installed state and installation depth.

[0016] (3) The high-strength mounting base of the thermal power plant accumulator is equipped with a rotatable bottom plate and a support rod, so that the bottom plate and the support rod are deployed in a triangular distribution with the frame, thereby reinforcing and supporting the frame, improving the support stability of the frame, and thus improving the overall stability of the thermal power plant accumulator mounting base.
