DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] In order to make the technical means, creative features, achieved objectives and functions of the present invention clearer and easier to understand, the present invention will be further described below in conjunction with the drawings and specific embodiments:

[0021] As Figures 1 to 3As shown in the figure, the present invention provides a production and curing system for prestressed concrete poles, including: a curing pool 1, a support frame 2, a curing cover 3, a connecting pipeline, an air conditioner, and a steam input pump; a placement groove is formed by the depression of the bottom surface of the curing pool 1, a support frame 2 straddles the curing pool 1, the support frame 2 is used to support the pole mold, there is a gap between the support frame 2 and the inner bottom wall of the placement groove, and the support frame 2 allows steam to pass through. A curing cover 3 is covered above the curing pool 1, and an exhaust hole is opened on the curing cover 3; the connecting pipeline includes: a main intake pipe, a three-way pipe, a first branch intake pipe, a second branch intake pipe, a first valve, and a second valve. One end of the main intake pipe is connected to the middle of the placement groove, the main intake pipe is connected to the outlet end of the three-way pipe, the first inlet end of the three-way pipe is connected to one end of the first branch intake pipe, the other end of the first branch intake pipe is connected to the air conditioner, the second inlet end of the three-way pipe is connected to one end of the second branch intake pipe, the other end of the second branch intake pipe is connected to the steam input pump, a first valve for opening and closing the first branch intake pipe is installed on the first branch intake pipe, and a second valve for opening and closing the second branch intake pipe is installed on the second branch intake pipe; a temperature sensor and a humidity sensor are installed on the inner wall of the placement groove, and the temperature sensor, the humidity sensor, the first valve, the second valve, the air conditioner, and the steam input pump are all connected to the control box.

[0022] In order to avoid safety accidents such as explosion when the curing cover 3 is lifted when the pressure in the placement groove is too high, a mechanical pressure sensing mechanism 4 is installed on the wall of the placement groove. The mechanical pressure sensing mechanism 4 is located beside the curing cover 3, and the mechanical pressure sensing mechanism 4 is used to limit the separation of the curing cover 3 from the curing pool 1 when the pressure in the placement groove is too high.

[0023] In order to avoid the curing cover 3 being easily separated from the curing cover 3 after the curing cover 3 is covered on the curing pool 1, a slot for inserting the curing cover 3 is formed by the depression of the top surface of the curing pool 1.

[0024] In order to design a simple structure of the pressure sensing mechanism during disassembly and realize the function that the mechanical pressure sensing mechanism 4 hinders the separation of the curing cover 3 from the curing pool 1 when the pressure is too high, the mechanical pressure sensing mechanism 4 includes: a sensing membrane 41, a moving rod 42, and an elastic member 43. An induction groove is formed by the depression of the inner wall of the placement groove, a sensing membrane 41 is installed on the wall of the placement groove, the sensing membrane 41 covers the induction groove, the sensing membrane 41 is made of an elastic material, the sensing membrane 41 is fixed to one end of the moving rod 42, the other end of the moving rod 42 is used to insert into the anti-separation hole opened on the curing cover 3, and the elastic member 43 connects the moving rod 42 to the inner wall of the induction groove, and the moving rod 42 can be kept away from the curing cover 3 under the elastic force of the elastic member 43.

[0025] In order to detect the pressure in the placement groove, a moving hole that communicates both the induction groove and the insertion slot is provided on the wall of the curing pool 1. One end of the moving rod 42 is provided in the moving hole. A displacement sensor 5 is installed at the end of the moving hole away from the induction groove. The displacement sensor 5 is used to detect the distance of the moving rod 42 to the position where the displacement sensor 5 is located. The displacement sensor 5 is connected to the control box. Since the greater the pressure in the placement groove, the smaller the distance of the moving rod 42 to the position where the displacement sensor 5 is located, by detecting the distance of the moving rod 42 to the position where the displacement sensor 5 is located, the magnitude of the pressure in the placement groove can be known, which is convenient for monitoring.

[0026] In order to have a distance between the bottom surface of the curing pool 1 and the ground, support columns 11 are installed at the bottom of the curing pool 1, and the support columns 11 stand on the ground.

[0027] When the concrete is put into the mold, it is very likely to fall from the mold gap to the bottom of the curing pool 1. There is a certain amount of water in the sedimentation tank. In this way, the concrete will not solidify when it enters the water. Therefore, the following design is made: at least two sedimentation tanks are formed at the bottom of the curing pool 1. All the sedimentation tanks are communicated with the placement groove. Each sedimentation tank is a frustum of a cone structure. The large end of each sedimentation tank is located above the small end. A discharge pipe 12 is installed at the bottom of the curing pool 1. Each sedimentation tank is communicated with a discharge pipe 12. An opening and closing mechanism for opening and closing the discharge pipe 12 is installed on the discharge pipe 12. In order to facilitate the discharge of the water with concrete, each sedimentation tank is designed as a frustum of a cone structure, and the design of the opening and closing mechanism realizes that it can only be used when discharge is required.

[0028] The opening and closing mechanism includes: a rotating cover 61 and a rotation limiting component. The discharge pipe 12 is provided with a discharge hole 120 that communicates with the sedimentation tank. The discharge hole 120 is in a J shape. A discharge hole 610 for communicating the discharge hole 120 is provided on the rotating cover 61. The rotating cover 61 can rotate relative to the discharge pipe 12. A rotation limiting component is installed beside the rotating cover 61. The rotation limiting component acts on the rotating cover 61, and the rotation limiting component is used to limit the rotation of the rotating cover 61.

[0029] A stirring frame 7 is arranged in each sedimentation tank. The stirring frame 7 is used to stir the water and concrete in the sedimentation tank. The stirring frame 7 is connected to the rotating cover 61.

[0030] The stirring frame 7 includes: a central rod 71, rotating arms 72 and cleaning arms 73. There are at least two rotating arms 72 and cleaning arms 73. Each cleaning arm 73 is in contact with the inner wall of the sedimentation tank. Each cleaning arm 73 is connected to the central rod 71 through a rotating arm 72. The central rod 71 is fixed to the rotating cover 61.

[0031] The rotation-limiting mechanism 62 includes: a first toothed ring 621, a second toothed ring 622, a mounting cylinder 623, and a first spring 624. The first toothed ring 621 is fixed to the outer wall of the rotary cover 61. The first toothed ring 621 can mesh with the second toothed ring 622. The second toothed ring 622 is fixed to the mounting cylinder 623. One end of the second toothed ring 622 is fixed to the first spring 624. The other end of the first spring 624 is fixed to the bottom of the curing pond 1. The mounting cylinder 623 can move in the vertical direction under the guidance of the curing pond 1. The mounting cylinder 623 cannot rotate relative to the curing pond 1. Under the elastic force of the first spring 624, the second toothed ring 622 can be kept meshed with the first toothed ring 621.

[0032] The elastic member 43 is a second spring.

[0033] The working principle of this embodiment:

[0034] During normal use, under the elastic force of the first spring 624, the first toothed ring 621 on the rotary cover 61 meshes with the second toothed ring 622, so as to keep the discharge hole 610 deviated from the discharge hole 120. In this way, the discharge pipe 12 is blocked, thus avoiding the water being drained out during use, ensuring that there is water in the sedimentation tank when the concrete drops, and preventing the dropped concrete from solidifying in the sedimentation tank.

[0035] When it is necessary to drain water and concrete, first, move the mounting cylinder 623 to disengage the second toothed ring 622 from the first toothed ring 621 and keep this state; then, rotate the rotary cover 61 to connect the discharge hole 610 on the rotary cover 61 with the discharge hole 120. During this process, the cleaning arm 73 sweeps across the inner wall of the sedimentation tank to prevent concrete from depositing in the sedimentation tank. At the same time, it also disturbs the concrete and water, so that the concrete can be smoothly discharged from the sedimentation tank after being separated from the water.

[0036] After all, the amount of dropped concrete is small. Therefore, when it drops into the water, the water separates the concrete. As a result, the concrete will not solidify and block the sedimentation tank in the water, which is convenient for subsequent discharge.

[0037] In this application, first, in order to enable both humidity and temperature to be adjustable, the air conditioner provides air at different temperatures, and the steam input pump provides steam. The amount of steam input per unit time is controlled by adjusting the opening degree of the second valve and the operation of the steam input pump, so that the humidity and temperature can be adjusted to the required values respectively. Subsequently, since the pressure in the placement tank increases after the input, in order to avoid explosion accidents caused by suddenly opening the curing cover 3, a mechanical pressure sensing mechanism 4 is designed to move according to the change of pressure, so as to realize that when the pressure in the placement tank is too high, the separation of the curing cover 3 from the curing pool 1 is restricted. Only when the pressure drops to a certain extent can the mechanical pressure sensing mechanism 4 release the curing cover 3 and allow the curing cover 3 to separate from the curing pool 1. Then, in order to avoid the difficulty of removing the concrete after it solidifies at the bottom of the curing pool 1, a certain amount of water is stored in the sedimentation tank, so that the bottom surface of the curing pool 1 is all sedimentation tanks, which facilitates the discharge of water and concrete. Then, in order to store a certain amount of water during use, an opening and closing mechanism is designed. Finally, in order to avoid the sedimentation of sand in the concrete due to the failure to mix water and concrete during discharge, a stirring frame 7 is connected to the rotating cover 61, so that rotating the rotating cover 61 can rotate the stirring frame 7, avoiding the situation of forgetting to rotate the stirring frame 7 and making the operation smoother.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. 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 solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
