Description

Technical Field

[0001] This utility model relates to the technical field of polyethylene composite pipes, specifically to a pressure-strengthening structure for polyethylene composite pipes. Background Technology

[0002] Polyethylene composite pipes have a wide range of applications. Firstly, in urban water supply systems, they can transport drinking water, supply fire-fighting water, and also transport industrial water. Secondly, in urban drainage systems, polyethylene composite pipes can transport sewage, rainwater, and industrial wastewater, and can withstand certain pressures. Furthermore, polyethylene composite pipes are widely used in the oil and gas transportation sector, capable of transporting energy resources such as crude oil, natural gas, and liquefied petroleum gas. Finally, they are also widely used in the chemical industry, transporting various chemical liquids and withstanding high pressures and temperatures. However, current polyethylene composite pipes have poor compressive strength; therefore, we propose a compressive strength-enhancing structure for polyethylene composite pipes.

[0003] The currently used polyethylene pipe compression reinforcement structure has a small contact area during extrusion and a small contact area with the extrusion point, thus affecting the overall compression resistance. Utility Model Content

[0004] The purpose of this utility model is to provide a polyethylene composite pipe compression-strengthening structure to solve the problem mentioned in the background art that the currently used polyethylene pipe compression-strengthening structure has a small contact area during extrusion and a small contact area with the extrusion position during contact, thus affecting the overall compression resistance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a polyethylene composite pipe pressure-resistant reinforcement structure, including a side plate, a polyethylene pipe shell mechanism fixedly connected to one side of the outer wall of the side plate, a polyethylene pipe inner connection mechanism fixedly installed on the inner surface of the polyethylene pipe shell mechanism, and a polyethylene pipe pressure-resistant mechanism fixedly installed on the inner surface of the polyethylene pipe inner connection mechanism.

[0006] Preferably, the polyethylene pipe shell mechanism includes a side limiting block, a polyethylene pipe shell body, and opening slots. The side limiting block is welded and installed on one side of the inner wall of the side connecting plate. The polyethylene pipe shell body is fixedly installed on the inner wall of the side limiting block. Opening slots are provided on both sides of the outer wall of the polyethylene pipe shell body.

[0007] Preferably, the grooves are arranged in a V-shape and are evenly distributed on the polyethylene pipe shell.

[0008] Preferably, the polyethylene pipe internal connection mechanism includes a polyethylene pipe connecting pipe, a trapezoidal block, and an abutment block. The polyethylene pipe connecting pipe is bonded and installed on the inner surface of the polyethylene pipe outer shell. Trapezoidal blocks are fixedly installed on both sides of the inner wall of the polyethylene pipe connecting pipe, and an abutment block is bonded and installed on the inner surface of the polyethylene pipe connecting pipe.

[0009] Preferably, the polyethylene pipe pressure-resistant mechanism includes an inner polyethylene pipe, a support block, a limiting groove, and a circular steel ball. The inner polyethylene pipe is bonded to the inner surface of the contact block. The support block is welded to the outer ring near the inner wall of the inner polyethylene pipe. The limiting groove is welded to the inner ring near the inner wall of the inner polyethylene pipe. The inner wall of the limiting groove is provided with a circular steel ball of a matching size.

[0010] Preferably, the support block is arranged in a trapezoidal structure, both sides of the limiting groove are rigid plate structures, and the limiting groove is arranged in a ring array on the inner pipe of the polyethylene pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. The polyethylene composite pipe pressure-strengthening structure, by setting an internal connection mechanism for the polyethylene pipe and a pressure-resistant mechanism for the polyethylene pipe, can enhance the internal pressure resistance of the polyethylene pipe. At the same time, during extrusion, the limiting groove can resist and limit the position of the round steel ball, thereby preventing deformation of the internal structure.

[0013] 2.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a polyethylene composite pipe compression-strengthening structure, including a side plate 1, a polyethylene pipe shell mechanism 2 fixedly connected to one side of the outer wall of the side plate 1, the polyethylene pipe shell mechanism 2 including a side limiting block 201, a polyethylene pipe shell 202 and a slot 203, the side limiting block 201 is welded to one side of the inner wall of the side plate 1, the polyethylene pipe shell 202 is fixedly installed on the inner wall of the side limiting block 201, and slots 203 are opened on both sides of the outer wall of the polyethylene pipe shell 202. The slots 203 are V-shaped, so that when the polyethylene pipe is compressed, the side limiting block 201 abuts against the polyethylene pipe shell 202, which can enhance the surface strength of the polyethylene pipe. The slots 203 are V-shaped and are evenly distributed on the polyethylene pipe shell 202. So when the polyethylene pipe is compressed, the polyethylene pipe extends to both sides, and the extended part abuts against the part of the polyethylene pipe surface being compressed, thereby enhancing the compression effect of the polyethylene pipe surface.

[0021] A polyethylene pipe inner connection mechanism 3 is fixedly installed on the inner surface of the polyethylene pipe outer shell mechanism 2. The polyethylene pipe inner connection mechanism 3 includes a polyethylene pipe connecting pipe 301, a trapezoidal block 302, and an abutment block 303. The polyethylene pipe connecting pipe 301 is bonded to the inner surface of the polyethylene pipe outer shell 202. Trapezoidal blocks 302 are fixedly installed on both sides of the inner wall of the polyethylene pipe connecting pipe 301. An abutment block 303 is bonded to the inner surface of the polyethylene pipe connecting pipe 301. When the polyethylene pipe is pressurized, the trapezoidal blocks 302 installed on the inner wall of the polyethylene pipe connecting pipe 301 can enhance the contact area when the polyethylene pipe is squeezed. At the same time, several inserts are installed inside the abutment block 303, so that the polyethylene pipe pressure-resistant mechanism 4 can be squeezed evenly during the compression.

[0022] A polyethylene pipe compression-resistant mechanism 4 is fixedly installed on the inner surface of the polyethylene pipe internal connection mechanism 3. The polyethylene pipe compression-resistant mechanism 4 includes an inner polyethylene pipe 401, a support block 402, a limiting groove 403, and a circular steel ball 404. The inner polyethylene pipe 401 is bonded to the inner surface of the contact block 303. The support block 402 is welded to the outer ring of the inner wall of the inner polyethylene pipe 401, and the limiting groove 403 is welded to the inner ring of the inner wall of the inner polyethylene pipe 401. The inner wall of the limiting groove 403 is provided with a circular steel ball 404 of a matching size. At the same time, the contact area between the support block 402 and the contact block 303 is large. Therefore, during compression, the circular steel ball 404 moves within the inner wall of the limiting groove 403, and can move in all directions. The support block 402 compresses the circular steel ball 404, thereby relieving the pressure on the polyethylene pipe. Simultaneously, the limiting groove 403 limits the circular steel ball 404, preventing deformation of the polyethylene pipe during compression. The support block 402 has a trapezoidal structure, and both sides of the limiting groove 403 are rigid plates. The limiting grooves 403 are arranged in a ring array on the inner pipe 401 of the polyethylene pipe. This allows the support block 402 to compress the circular steel ball 404 over a large area during compression, while the limiting groove 403 limits the position of the circular steel ball 404, preventing it from compressing the sides and affecting the compressive strength of the polyethylene pipe.

[0023] Working principle: First, the device is placed in the designated position. When pressurizing the polyethylene pipe, the trapezoidal block 302 installed on the inner wall of the polyethylene pipe connecting pipe 301 can enhance the contact area during the extrusion of the polyethylene pipe. At the same time, several inserts are installed inside the contact block 303, so that the polyethylene pipe compression mechanism 4 can be uniformly extruded during extrusion. Meanwhile, the contact area between the support block 402 and the contact block 303 is large. Therefore, during extrusion, the round steel ball 404 moves in the inner wall of the limiting groove 403, and can be extruded from all directions, thereby relieving the extrusion force on the polyethylene pipe. At the same time, the limiting groove 403 limits the round steel ball 404, which can prevent the polyethylene pipe from deforming during extrusion. In addition, the groove 203 is set in a V-shaped structure. During extrusion, the side limiting block 201 abuts against the polyethylene pipe outer shell 202, which can enhance the surface strength of the polyethylene pipe. This completes the operation process of a polyethylene composite pipe compression reinforcement structure.
