[0001] The utility model relates to the technical field of conversion valves, in particular to a high- and low-pressure water flow automatic conversion valve for hydraulic hole expansion and cavitation. Background Art

[0002] With the mining of coal mines, because coal mines are deep and easy to burn, ordinary rotary hole mining can easily ignite the coal mines. Therefore, water pressure drilling is used. When hydraulic drilling is performed, the water flow inside the water pipe needs to be detected. Therefore, a hydraulic hole expansion and hole making high and low pressure water flow automatic conversion valve is used to convert the water flow inside the water pipe.

[0003] However, the existing processing equipment has the following shortcomings:

[0008] Preferably, a rotating column is fixedly connected to the inner wall of the limit block, and a rotating groove is opened on the side of the limit block. By arranging a rotating column inside the limit block, the rotating block can be limited, thereby reducing the situation where the rotating block rotates randomly without a fixed point when the equipment is in use, making it difficult for the protective cover to rotate along the specified track.

[0014] Compared with the prior art, the advantages and positive effects of the utility model are:

[0015] 1. In the utility model, when using the device, the user connects and installs the device with the water pipe that needs to monitor the water flow, detects and converts the water flow in the water pipe, and when using the device, the user rotates the protective cover, and then the protective cover rotates on the surface of the rotating column. When the protective cover rotates, it drives the first spring to displace and deform to generate a rotational force, and then the protective cover and the surface of the display are protected. By setting the protective device, the surface of the display is effectively protected, and the surface of the display is protected. When the device is used after installation, since the device is used in the field with a relatively complex environment, the display is often exposed to a harsh environment, which is easy to cause certain damage to the surface of the display, affecting the user's observation of the display value at all times, making it difficult for the user to monitor the water flow of the device, thereby improving the practicality of the device.

[0016] 2. In the utility model, by setting a limiting device, when using the equipment, the user presses the pressure block, and then the pressure block moves, which drives the card plate to move. When the card plate moves, it drives the second spring to displace and deform to generate elastic force. Then the card plate moves out of the inside of the card hole, and then the first connecting block loses its restraint. By setting a limiting device, the protective cover is effectively restricted, which plays a role in restricting the protective cover. When using the equipment, after the user combines the protective cover with the surface of the display, the equipment works in a harsh environment, which easily causes the protective cover to separate from the surface of the display, thereby improving the stability of the protective cover when the equipment is in use.

[0025] The specific arrangement and function of the protection device 6 and the limiting device 7 will be described in detail below.

[0026] In this embodiment: the protection device 6 is arranged on the surface of the display 5, and the protection device 6 includes a protection cover and a limit block 62. The limit block 62 is fixedly connected to the surface of the display 5. The protection cover is arranged on the surface of the display 5. A rotating block 63 is fixedly connected to the side of the protection cover. The rotating block 63 is rotatably connected to the inner wall of the limit block 62.

[0027] Specifically, a rotating column 64 is fixedly connected to the inner wall of the limiting block 62 , and a rotating groove 65 is formed on the side of the rotating block 63 .

[0028] In this embodiment: by setting a rotating column 64 inside the limit block 62, the rotating block 63 can be limited, which reduces the situation where the rotating block 63 rotates randomly without a fixed point when the equipment is in use, making it difficult for the protective cover 61 to rotate along the specified track.

[0029] Specifically, the rotating column 64 is rotatably connected to the inner wall of the rotating groove 65 , and a limiting groove 66 is provided on the inner wall of the rotating column 64 . The limiting groove 66 is provided to facilitate limiting the first spring 67 .

[0030] Specifically, a first spring 67 is disposed inside the limiting groove 66 , and two ends of the first spring 67 are respectively fixedly connected to the limiting groove 66 and the inner wall of the rotation groove 65 . The first spring 67 is disposed to facilitate applying a restoring elastic force to the protective cover 61 .

[0031] In this embodiment: a limiting device 7 is provided on the surface of the display 5, and the limiting device 7 includes a first connecting block 71 and a second connecting block 72. The first connecting block 71 is fixedly connected to the side of the protective cover 61, and the second connecting block 72 is fixedly connected to the side of the display 5. The inner wall of the first connecting block 71 is provided with a clamping hole 74, and the inner wall of the second connecting block 72 is provided with a pressing hole 73. The inner wall of the pressing hole 73 is slidably connected with a clamping plate 75, and the interior of the pressing hole 73 is fixedly connected with a sliding rod 77. The clamping plate 75 is slidably connected to the interior of the sliding rod 77, and one end of the clamping plate 75 is clamped with the interior of the clamping hole 74.

[0032] In this embodiment, by providing a clamping plate 75 inside the pressure hole 73, the protective cover 61 can be restricted, thereby reducing the possibility that the protective cover 61 rotates away from the surface of the display 5 when the device is in use.

[0033] Specifically, a second spring 76 is fixedly connected to the surface of the card plate 75 , and one end of the second spring 76 away from the card plate 75 is fixedly connected to the inner wall of the pressure hole 73 . The second spring 76 is provided to facilitate applying a restoring elastic force to the card plate 75 .

[0034] Specifically, a pressing block 78 is fixedly connected to the surface of the clamping plate 75 , and the pressing block 78 is slidably connected to the inner wall of the pressing hole 73 . The pressing block 78 is provided to facilitate the movement of the clamping plate 75 .

[0035] Working principle: When using the device, the user connects and installs the device to the water pipe where the water flow needs to be monitored, and detects and converts the water flow in the water pipe. When using the device, the user rotates the protective cover 61, and then the protective cover 61 rotates on the surface of the rotating column 64. When the protective cover 61 rotates, it drives the first spring 67 to displace and deform to generate a rotational force, and then the protective cover 61 and the surface of the display 5 are protected. By setting the protective device 6, the surface of the display 5 is effectively protected, which plays a role in protecting the surface of the display 5. When the device is used after installation, since the device is used in the wild with a relatively complex environment, the display 5 is often exposed to a harsh environment, which is easy to cause certain damage to the surface of the display 5, affecting the user's observation of the value of the display 5 at all times, making it difficult for the user to monitor the water flow of the device, thereby improving the practicability of the device.

[0036] When using the device, the user presses the pressure block 78, and the pressure block 78 moves, driving the card plate 75 to move. When the card plate 75 moves, it drives the second spring 76 to displace and deform to generate elastic force. Then the card plate 75 moves out of the inside of the card hole 74, and then the first connecting block 71 loses its restraint. By setting the limiting device 7, the protective cover 61 is effectively restricted, which plays a role in restricting the protective cover 61. When using the device, after the user combines the protective cover 61 with the surface of the display 5, the device is working in a harsh environment, which easily causes the protective cover 61 to be separated from the surface of the display 5, thereby improving the stability of the protective cover 61 when the device is in use.
