[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments. The specific embodiments are as follows:

[0028] like Figures 1 to 3As shown, a valve safety opening device includes a tripod 1. A crossbar 10 is threaded onto the outer wall of the tripod 1. A locking assembly 2 is fixedly installed at the bottom of the tripod 1. An adjusting handle 3 is fixedly installed at the top of the tripod 1. A positioning assembly 4 is fixedly installed on the outer wall of the adjusting handle 3. A crank catch 5 is fixedly installed at the bottom of the tripod 1. The locking assembly 2 includes a threaded tube 20, which is fixedly installed inside the crossbar 10. A threaded rod 21 is threaded inside the threaded tube 20. A locking connector 22 is fixedly installed at the bottom of the threaded rod 21. The locking connector 22 is cylindrical in shape and engages... The outer wall of the head 22 is provided with protrusions. The shape of the clamp 22 is cylindrical or square, which can engage with the center of the valve handle. The groove at the center of the valve handle is usually circular or square and is a separate groove. In order to make the clamp 22 fit tightly with the groove, the protrusion is provided on the outside. Therefore, when the clamp 22 rotates, it can drive the valve to rotate through the protrusion, thereby achieving the purpose of opening and closing the valve. A handwheel is fixedly installed at the end of the threaded rod 21 away from the clamp 22. The handwheel can be operated to drive the threaded rod 21 to rotate, thereby driving the clamp 22 to achieve lifting and lowering displacement.

[0029] It should be noted that there are three crank clamps 5, and each of the three crank clamps 5 includes a connecting rod 50. The three connecting rods 50 are fixedly installed at the bottom of the tripod 1. The end of each of the three connecting rods 50 away from the tripod 1 is fixedly installed with a clamping head 51. The three clamping heads 51 are C-shaped, and the inner wall of each clamping head 51 is provided with a friction pad. Since the center of the valve handle may not have a groove or other structural design that prevents it from connecting to the clamping head 22, the clamping head 51 can be used to fit against the connecting rod on the inner wall of the valve handle. By installing the connecting rod 50 and the clamping head 51 at the bottom of the three ends of the tripod 1, the clamping head 51 can engage the connecting rod, so that when the clamping head 51 rotates, it can drive the valve handle to rotate together, thereby achieving the purpose of opening and closing the valve.

[0030] The adjusting handle 3 includes a sleeve 30, which is fixedly installed on the top of the crossbar 10. A handle 31 is slidably installed inside the sleeve 30. The handle 31 is U-shaped. An anti-slip plate 33 is fixedly installed at one end of the handle 31 inside the sleeve 30. An anti-slip block 34 is fixedly installed on the inner wall of the sleeve 30. The positioning component 4 includes a mounting bracket 40, which is L-shaped and fixedly installed on the outer wall of the sleeve 30. A positioning screw 41 is threaded inside the mounting bracket 40. A threaded groove is formed inside the handle 31. 32. The number of threaded grooves 32 and the length of handle 31 can be increased or decreased according to the actual situation. The positioning screw 41 is adapted to the threaded groove 32. Two sleeves 30 are installed on the top of the crossbar 10, and the handle 31 is inserted into the two sleeves 30 in a "U" shape. The handle 31 has a threaded groove 32 that is adapted to the positioning screw 41. The overall length of the structure can be extended by pulling the handle 31 inside the sleeve 30. After adjusting the length, the positioning screw 41 is rotated to connect with the threaded groove 32 at the corresponding position on the handle 31 to form a positioning.

[0031] In addition, two brackets 60 are fixedly installed at the bottom of the crossbar 10. Lighting lamps 61 are fixedly installed inside the two brackets 60. Since the environment inside the tunnel or under the manhole cover is dark, the lighting lamps 61 can help to position the clamp 51 and the snap-fit ​​connector 22 with the valve handle.

[0032] Working principle: The operator first adjusts the length of the extension between the handle 31 and the sleeve 30 to extend the overall device. At the same time, depending on the structure of the valve handle in the tunnel or underground, the operator selects to connect with the fitting clamp 51 or the snap-fit ​​connector 22. If the valve handle has a slot, the snap-fit ​​connector 22 can be moved by rotating the threaded rod 21. Once the snap-fit ​​connector 22 is above the position of the fitting clamp 51, the operator can start the operation. The operator manually holds the handle 31 from the outside, inserts the snap-fit ​​connector 22 into the valve handle slot, and rotates clockwise to open the valve inside the tunnel. If the valve handle does not have a slot, the operator rotates the threaded rod 21 to move the snap-fit ​​connector 22 above the fitting clamp 51. The three fitting clamps 51 directly engage the three connecting rods inside the valve handle. At the same time, rotating the handle 31 will drive the valve handle to rotate to start or close the device under the action of the fitting clamps 51. The operator does not need to enter a small, dark environment to open the valve, thereby improving safety and maintenance efficiency.

[0033] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
