[0022] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0023] This utility model provides a device for testing water pressure inside reinforced concrete pipes, such as... Figure 1-6As shown, the water pressure testing device for reinforced concrete pipes includes: a reinforced concrete pipe body 101; a steel cylinder 1 disposed within the reinforced concrete pipe body 101; multiple steel rings 2 assembled on the steel cylinder 1; an inner support frame 3 fixedly installed on the inner wall of the steel cylinder 1, the inner support frame 3 being used to support the steel cylinder 1; an exhaust port 5 assembled on the steel cylinder 1, the exhaust port 5 being equipped with a pressure gauge 8 and a ball valve 9; a water inlet 6 disposed on the steel cylinder 1, the water inlet 6 being equipped with a three-way valve; and a water seal 7 disposed on the steel cylinder 1.

[0024] In this embodiment, when conducting a water pressure test on the reinforced concrete pipe body 101, firstly, a three-way valve on the water inlet 6 is used. One port is connected to a tap water pipe, and the other port is connected to a pressure pump to control the pressure. The steel cylinder 1 is equipped with internal reinforcing bars. Water is injected into the steel cylinder 1 and the reinforced concrete pipe body 101 through the water inlet 6 until all the air in the steel cylinder 1 is expelled. Then, the vent 5 is closed. The pressure pump is used to pressurize the steel cylinder 1. The pressure increase rate should be uniform. During the pressurization process, check whether there are damp patches or water droplets on the surface of the steel cylinder 1 and record the results. The pressure is observed through the pressure gauge 8. When the pressure reaches the test pressure, it is maintained at a constant pressure for a period of time. If the pressure drops during this period, water can be injected to replenish the pressure, but it must not exceed the test pressure. After stopping the water injection and pressure replenishment, the pressure is stabilized for a period of time, and the pressure drop is observed. Thus, a water pressure test can be conducted on the reinforced concrete pipe body 101. The entire device can conduct a water pressure test on the reinforced concrete pipe body 101, and the overall structure is simple and low in cost.

[0025] In a further preferred embodiment of the present invention, a heightening support frame 4 is provided inside the steel cylinder 1, the heightening support frame 4 is connected to the inner support frame 3, and the heightening support frame 4 is used to support the steel cylinder 1.

[0026] In this embodiment, the heightened support frame 4 is used to support the steel cylinder 1, thereby further improving the stability of the support for the steel cylinder 1.

[0027] In a further preferred embodiment of the present invention, a protective cover 10 is provided on the reinforced concrete pipe body 101. The protective cover 10 is used to protect the top of the reinforced concrete pipe body 101. A connecting shell 11 is fixedly installed on the protective cover 10. An operating frame 12 is slidably arranged on the connecting shell 11. The operating frame 12 is used to operate the protective cover 10.

[0028] In this embodiment, the protective cover 10 can protect the top of the reinforced concrete pipe body 101, preventing external debris from entering the reinforced concrete pipe body 101. At the same time, when a water pressure test is required inside the reinforced concrete pipe body 101, the protective cover 110 can be removed according to the actual needs.

[0029] In a further preferred embodiment of this utility model, a warning mechanism is provided on the connecting shell 11 and the operating frame 12. The warning mechanism is used to warn strangers when they open the protective cover 10. The warning mechanism includes: a spring 13 sleeved on the operating frame 12; a baffle 14 fixedly installed at the bottom of the operating frame 12; and an alarm 15 assembled in the connecting shell 11. The alarm 15 is provided with a trigger button 16, and the trigger button 16 is compatible with the alarm 15.

[0030] In this embodiment, when a stranger operates the operating frame 12 to open the protective cover 10, the operating frame 12 will cause the baffle 14 to move upward and contact the trigger button 16 when the stranger lifts the operating frame 12. As a result, the alarm 15 will be activated and emit an alarm sound, which can serve as a warning to strangers and thus improve the safety of the components inside the reinforced concrete pipe body 101.

[0031] In a further preferred embodiment of the present invention, an adjustment mechanism is provided on the connecting shell 11. The adjustment mechanism is used to adjust the position of the warning device 15. The adjustment mechanism includes: a lead screw 17 rotatably mounted on the connecting shell 11 via a damping shaft; and a mounting block 18 threaded onto the lead screw 17. The mounting block 18 and the warning device 15 are fixedly connected.

[0032] In this embodiment, when an operator needs to open the protective cover 10 by operating the control frame 12, the screw 17 is rotated. A limit rod is fixedly installed inside the connecting shell 11. The limit rod and the mounting block 18 are slidably connected. The limit rod limits the mounting block 18, thereby allowing the screw 17 to stably move the mounting block 18. This allows the position of the alarm 15 and the trigger button 16 to be adjusted. The trigger button 16 is moved to one side of the baffle 14. Then, when the operator operates the control frame 12, the baffle 14 will not contact the trigger button 16, and the alarm 15 will not emit an alarm sound.

[0033] In a further preferred embodiment of the present invention, a limiting mechanism is provided inside the connecting shell 11. The limiting mechanism is used to limit the movement of the operating frame 12. The limiting mechanism includes: a slide rod 19 fixedly installed inside the connecting shell 11, the slide rod 19 and the baffle 14 being slidably connected; and a limiting block 20 fixedly sleeved on the slide rod 19.

[0034] In this embodiment, when the operating frame 12 is lifted, the operating frame 12 moves upward on the connecting shell 11. When the operating frame 12 contacts the limiting block 20, the operating frame 12 cannot continue to move on the connecting shell 11, thereby preventing the operating frame 12 from driving the baffle 14 to excessively squeeze the trigger button 16, thus protecting the trigger button 16 and the alarm 15.

[0035] In a further preferred embodiment of this utility model, a positioning frame is fixedly installed on the inner support frame 3, and a positioning rod is fixedly installed on the bottom of the protective cover 10, with the positioning rod and the positioning frame being adapted and connected.

[0036] In this embodiment, the positioning frame and the positioning rod work together to make it easy to accurately place the protective cover 10 on the reinforced concrete pipe body 101.

[0037] In summary, compared with related technologies, the entire device can perform a hydrostatic test on the reinforced concrete pipe body 101, and the overall structure is simple and the cost is low.

[0038] It should be understood, in the several embodiments provided in this application, that the disclosed apparatus may be implemented in other ways.
