The hydrogen refueling gun is the core equipment in the hydrogen refueling station to achieve safe and efficient hydrogen refueling to hydrogen fuel cell vehicles. During the entire hydrogen refueling process, it is necessary to ensure that the connection between the hydrogen refueling gun and the hydrogen refueling port is firm to prevent hydrogen leakage. At the same time, during the hydrogen refueling process, in order to protect the safety of the operator and ensure the smooth progress of the hydrogen refueling process, a protective cover is often installed on the surface of the hydrogen refueling gun output head to prevent the operator from direct contact with the hydrogen refueling gun and frostbite, while preventing condensation or ice on the hydrogen refueling gun output head, causing the hydrogen refueling gun valve to get stuck or leak, making it difficult to pull out the hydrogen refueling gun.

DETAILED DESCRIPTION

[0024] The technical solution of the present application will be further described in detail below in conjunction with specific implementation methods.

[0025] like Figure 1-7 As shown, the present invention provides a technical solution: a hydrogenation gun for a hydrogenation station with temperature measurement, comprising a hydrogenation gun body 1, an output head 101 being fixedly mounted on one end of the top of the hydrogenation gun body 1, a retaining ring 102 being fixedly mounted on the side of the output head 101 close to the hydrogenation gun body 1, and the retaining ring 102 is provided to push the protective collar 5 so that the sliding fixing ring 3 slides on the surface of the output head 101 and is tightly attached to the side of the retaining ring 102, thereby limiting the movement range of the sliding fixing ring 3 on the surface of the output head 101;

[0026] The surface of the output head 101 is located on one side of the retaining ring 102 and is provided with six groups of mounting grooves 103 at equal angles. A mounting slide rod 104 is fixedly installed inside the mounting groove 103. The surface of the mounting slide rod 104 located inside the mounting groove 103 is provided with a lifting spring 105. The surface of the output head 101 away from the retaining ring 102 is provided with six groups of limiting grooves 106 at equal angles. Due to the provision of the lifting spring 105, the sliding seat 401 can slide on the surface of the mounting slide rod 104 under the rebound action of the lifting spring 105, driving the connecting ring 4 to slide on the surface of the output head 101, and pushing the protective ring 5 to move to cover the plug-in position of the output head 101 and the vehicle hydrogen refueling port for shielding and protection.

[0027] A clamping and fixing mounting plate 2 is fixedly installed on the top of the hydrogenation gun body 1, and a mounting side plate 201 is symmetrically fixedly installed on one side of the top of the clamping and fixing mounting plate 2. A mounting column 202 is fixedly installed on the top between the two groups of mounting side plates 201. A rotating clamping plate 203 is rotatably installed on the surface of the mounting column 202 located between the two groups of mounting side plates 201, and a fixed clamping tooth 204 is fixedly installed on one side of the bottom of the rotating clamping plate 203. The top of the hydrogenation gun body 1 is located on one side of the clamping and fixing mounting plate 2 and is slidably installed with a sliding fixing ring 3. A clamping and fixing tooth plate 301 is fixedly installed on the top of the surface of the sliding fixing ring 3, and the fixed teeth 204 correspond to the positions of the clamping and fixing tooth plate 301 and have the same shape. By providing the fixed teeth 204 and the clamping and fixing tooth plate 301, the sliding fixing ring 3 is pushed to slide on the surface of the output head 101 until the clamping and fixing tooth plate 301 is pushed to the bottom of the fixed teeth 204, so that the fixed teeth 204 are clamped and fixed on the top of the clamping and fixing tooth plate 301, thereby clamping and fixing the sliding fixing ring 3, so that the sliding fixing ring 3 can be clamped and fixed on one side of the retaining ring 102 and will not slide freely on the surface of the output head 101.

[0028] Three sets of positioning rings 205 are fixedly installed on the side of the clamping and fixing mounting plate 2 and the rotating clamping plate 203 away from the fixed clamping teeth 204, and positioning posts 206 are fixedly installed inside the positioning rings 205 on the side of the clamping and fixing mounting plate 2 and the rotating clamping plate 203 away from the fixed clamping teeth 204. A return spring 207 is provided between the positioning posts 206 on the opposite side of the clamping and fixing mounting plate 2 and the rotating clamping plate 203. 07. Press and rotate the card plate 203 away from one end of the fixed tooth 204, so that the reset spring 207 is squeezed and deformed between the two sets of corresponding positioning posts 206, driving the rotating card plate 203 to rotate around the mounting post 202, so that the fixed tooth 204 is tilted away from the clamping fixed tooth plate 301, and the sliding fixed ring 3 is loosened. At the same time, the reset spring 207 is squeezed and deformed between the corresponding positioning ring 205 and the positioning post 206, ensuring that the two ends of the reset spring 207 will not be misaligned or deflected.

[0029] A connecting collar 4 is fixedly installed on one side of the sliding fixing ring 3. Six groups of sliding seats 401 are fixedly installed at equal angles on the inner wall of the connecting collar 4 away from the side of the sliding fixing ring 3. The sliding seats 401 correspond to the positions of the mounting slide grooves 103, and the sliding seats 401 are slidably connected to the surfaces of the mounting slide grooves 103. Six groups of connecting clamps 402 are fixedly installed at equal angles on the surface of the connecting collar 4. By providing the connecting clamps 402, after the connecting clamps 402 are inserted into the corresponding connecting clamping grooves 605, the connecting clamps 604 are rotated to drive the connecting clamping grooves 605 to rotate on the surface of the connecting clamps 402, thereby clamping the connecting clamps 402 into the connecting clamping grooves 605, so that the connecting collar 4 is connected and fixed to the protective collar 5;

[0030] Six groups of positioning holes 403 are provided at equal angles on the side of the connecting collar 4 away from the sliding fixing ring 3. A protective collar 5 is provided on the side of the connecting collar 4 away from the sliding fixing ring 3. Six groups of electrical clamping posts 501 are fixedly mounted on one side of the protective collar 5. The electrical clamping posts 501 correspond to the positions of the positioning holes 403 and have the same shape. Due to the presence of the positioning holes 403 and the electrical clamping posts 501, when the electrical clamping posts 501 on one side of the protective collar 5 are inserted into the corresponding positioning holes 403, it is ensured that the protective collar 5 will not deflect or misalign when it is clamped and fixed to the side of the connecting collar 4.

[0031] Six groups of limiting ball groups 502 are inlaid and rolled on the inner wall of the protective collar 5 at equal angles. Each group of limiting ball groups 502 includes six balls, and the position of the limiting ball groups 502 corresponds to the position of the limiting slide groove 106. A temperature sensor 503 is inlaid and installed on the inner wall of the protective collar 5 between two adjacent groups of limiting ball groups 502. By providing the limiting ball groups 502 and the limiting slide groove 106, when the protective collar 5 slides on the surface of the output head 101, it drives the limiting ball groups 502 to roll inside the limiting slide groove 106, thereby reducing the friction of the protective collar 5 when sliding on the surface of the output head 101. At the same time, the temperature sensor 503 covers the surface of the connection between the output head 101 and the vehicle hydrogen refueling port, and can monitor the temperature at the interface in real time.

[0032] A clamping connection mechanism 6 is fixedly mounted on the side of the protective collar 5 near the connecting collar 4. The clamping connection mechanism 6 includes six sets of mounting blocks 601, which are fixedly connected to the surface of the protective collar 5. An arc-shaped slide bar 602 is fixedly mounted between two adjacent sets of mounting blocks 601, and a sliding block 603 is slidably mounted on the surface of the arc-shaped slide bar 602. Due to the presence of the arc-shaped slide bar 602, rotating the connecting clamp 604 drives the sliding block 603 to slide on the surface of the corresponding arc-shaped slide bar 602, ensuring that the connecting clamp 604 will not be misaligned or deflected during rotation.

[0033] A connecting snap ring 604 is fixedly installed on one side of the six groups of sliding blocks 603, and six groups of connecting grooves 605 are provided at equal angles on the inner wall of the connecting snap ring 604, and the connecting grooves 605 correspond to the positions of the connecting blocks 402. A fixing spring 606 is provided on the surface of the arc-shaped sliding rod 602 on one side of the sliding block 603. By providing a fixing spring 606, after the connecting snap ring 604 is clamped on the surface of the connecting sleeve 4 and the connecting sleeve 402 is inserted into the corresponding connecting groove 605, the sliding block 603 is pushed to slide on the surface of the corresponding arc-shaped sliding rod 602 under the rebound action of the fixing spring 606, driving the connecting snap ring 604 to rotate on the surface of the connecting sleeve 4, so that the connecting block 402 is clamped and fixed inside the corresponding connecting groove 605, and the protective sleeve 5 is connected and fixed to the connecting sleeve 4.

[0034] A fixed block 607 is fixedly installed on one side of the mounting block 601, and a fixed clamping plate 608 is rotatably installed on the surface of the fixed block 607. A fixed hook 609 is fixedly installed on one side of the sliding block 603, and the position of the fixed hook 609 corresponds to that of the fixed clamping plate 608. Because of the fixed clamping plate 608 and the fixed hook 609, after the connecting snap ring 604 is clamped on the surface of the connecting clamp block 402, the sliding block 603 is pushed on the surface of the arc-shaped slide rod 602 until the sliding block 603 is tightly attached to the mounting block 601, and then the fixed clamping plate 608 is rotated to clamp and connect with the corresponding fixed hook 609, so that the sliding block 603 is clamped and fixed to the corresponding mounting block 601, ensuring that the connecting snap ring 604 will not rotate at will on the surface of the connecting clamp block 402.

[0035] The working principle of the present invention is:

[0036] Hold the connecting ring 4 and rotate the connecting ring 604 on the surface of the protective ring 5 to make the sliding block 603 slide on the surface of the corresponding arc-shaped slide rod 602, squeeze the fixing spring 606 to deform, and put the protective ring 5 and the connecting ring 4 close to each other. Insert the electrical card column 501 on one side of the protective ring 5 into the corresponding positioning hole 403 on the surface of the connecting ring 4 until the connecting card block 402 on the surface of the connecting ring 4 is stuck in the corresponding connecting card groove 605. Release the connecting ring 604 under the rebound effect of the fixing spring 606. Under the action of the screw thread 602, the sliding block 603 slides on the surface of the corresponding arc-shaped sliding rod 602, driving the connecting clamping ring 604 to rotate on the surface of the connecting clamping block 402, thereby clamping and fixing the connecting clamping block 402 inside the corresponding connecting clamping groove 605. After the sliding block 603 is tightly attached to the mounting block 601, the fixed clamping plate 608 is rotated to clamp on the surface of the corresponding fixed clamping hook 609, ensuring that the connecting clamping ring 604 will not rotate freely on the surface of the connecting clamping block 402, and at the same time facilitating the connection and fixation or separation and replacement of the protective collar 5 and the connecting collar 4.

[0037] Push the protective collar 5 to drive the connecting collar 4 and the sliding fixing ring 3 to slide on the surface of the output head 101, drive the sliding seat 401 to slide inside the corresponding mounting slot 103, squeeze the top spring 105 to deform, and make the clamping and fixing tooth plate 301 on the surface of the sliding fixing ring 3 slide past the bottom of the fixed tooth 204. Under the rebound action of the reset spring 207, the fixed tooth 204 is clamped and fixed on the top of the clamping and fixing tooth plate 301 until the sliding fixing ring 3 is tightly attached to the side of the retaining ring 102, and the output head 101 is connected to the vehicle. After the hydrogen port is plugged in and fixed, the rotating card plate 203 is pressed to rotate the rotating card plate 203 around the mounting column 202, driving the fixed tooth 204 to disengage the clamping fixed tooth plate 301, and under the rebound action of the lifting spring 105, the sliding seat 401 is lifted to slide inside the mounting slot 103, so that the connecting ring 4 drives the protective ring 5 to slide on the surface of the output head 101 until the protective ring 5 covers the surface of the connection between the output head 101 and the vehicle hydrogen filling port, thereby shielding and protecting the surface of the connection between the output head 101 and the vehicle hydrogen filling port.
