Description

Technical Field

[0001] The utility model relates to the technical field of methane detection, and specifically, to a methane remote control detection device. Background Art

[0002] Methane is a non-polar molecule with a regular tetrahedral structure and is the simplest organic compound. As the main component of conventional natural gas, shale gas, combustible ice, etc., methane is a very important carbon-based resource. It is one of the main non-CO2 greenhouse gases. In the stratosphere of the atmosphere, methane will be decomposed into water vapor (clouds), resulting in the destruction of the ozone layer.

[0003] The utility model with the publication number CN216622164U discloses a methane gas detection device, including a bracket. An upper part of the inner cavity of the bracket is fixedly installed with a support plate. A methane detector is placed on the upper end of the support plate. A telescopic rod is fixedly installed in the middle of the lower end of the methane detector. A detection probe is fixedly installed at the lower end of the telescopic rod. A macroporous adsorption material layer is fixedly installed on the outer surface of the detection probe. A chute is arranged in the middle of the left wall of the inner cavity of the bracket. In the above application document, the methane detector is clamped and fixed by rotating a positive and negative screw rod to drive two groups of clamping plates to move. When the device is used, it may be accidentally touched to drive the positive and negative screw rod to rotate, resulting in the two groups of clamping plates loosening the clamping of the methane detector, causing the methane detector to become loose. Utility Model Content

[0004] The utility model provides a methane remote control detection device, which solves the problems in the related technology.

[0005] The technical solution of the utility model is as follows: A methane remote detection device includes a frame. A through hole is opened at the bottom inside the frame. A support plate is fixedly connected to the inner side of the frame. A detector body is arranged on the top of the support plate. A detection tube is arranged at the bottom of the detector body. A telescopic tube is slidably connected inside the detection tube. A detection head is arranged at the bottom of the telescopic tube. A chute is opened on the inner side wall of the frame. A sliding plate is slidably connected inside the chute. The telescopic tube penetrates and is fixedly connected to the sliding plate. A threaded rod A is rotatably connected inside the chute. A motor is arranged on the top of the frame. The output shaft of the motor is fixedly connected to the threaded rod A. The sliding plate is threadedly connected to the threaded rod A. An anti-misoperation clamping mechanism and an anti-overclamping mechanism are arranged inside the frame; The anti-misoperation clamping mechanism includes a fixed frame and a rotating rod. The fixed frame is fixedly connected to the inner side of the frame. A clamping plate is slidably connected inside the fixed frame. A threaded rod B is rotatably connected inside the fixed frame. A groove is opened on the side surface of the threaded rod B. A clamping groove is opened on the inner wall of the groove. A return spring is fixedly connected to the inner side wall of the groove. The rotating rod penetrates through the side surface of the threaded rod B. A moving block is fixedly connected to the side surface of the rotating rod. A groove is opened on the surface of the moving block. A telescopic spring is arranged inside the groove. An arc-shaped block is slidably connected inside the groove through the telescopic spring.

[0006] The diameter of the through hole is larger than the diameter of the detection head. A macroporous adsorption material layer with a zeolitic imidazolate framework structure is arranged on the surface of the detection head. The detection head can pass through the through hole. The macroporous adsorption material layer with a zeolitic imidazolate framework structure can increase the signal strength, improve the sensitivity, does not require frequent addition of consumables, is simple to maintain, does not require laser modulation and signal demodulation, has strong anti-interference ability, strong robustness, and a wide range of applications.

[0007] The number of the clamping plates is set to two groups. The two groups of clamping plates are threadedly connected to the threaded rod B through internal threads, and the internal thread directions of the two groups of clamping plates are opposite. When the threaded rod B rotates, it will drive the two groups of clamping plates to move closer or move away from each other.

[0008] One end of the arc-shaped block away from the telescopic spring is initially in contact with the inner wall of the threaded rod B, and the telescopic spring is initially in a taut state. When the telescopic spring rebounds, it will drive the arc-shaped block to partially pop out of the groove.

[0009] The arc surface of the arc-shaped block faces the direction of the rotating rod. The depth of the groove is greater than the length of the arc-shaped block. When the arc surface of the arc-shaped block is squeezed, it will move into the groove, and the arc-shaped block can be completely retracted into the groove.

[0010] The opening size of the card slot is equal to that of the groove, and the number of the card slots is set to six groups. The arc-shaped block can be inserted into the card slot. When the arc-shaped block is inserted into the card slot, rotating the rotating rod will drive the threaded rod B to rotate through the cooperation between the arc-shaped block and the card slot.

[0011] One end of the moving block away from the rotating rod is initially in contact with the reset spring. When the moving block moves leftward, it will squeeze the reset spring and make it gradually tense.

[0012] The anti-over-clamping mechanism includes a top plate and a pneumatic chamber. The top plate is fixedly connected to the inside of the frame, the pneumatic chamber is fixedly connected to the inside of the clamping plate, one end of the pneumatic chamber is provided with an airbag, a piston in the other end of the pneumatic chamber is slidably connected with a push rod, and the top of the push rod is fixedly connected with a deceleration block.

[0013] The airbag is located on the side of the clamping plate close to the detector body. The airbag is in an inflated state initially. When the clamping plate clamps the detector body, the airbag will be squeezed by the detector body, and the air pressure in it will enter the pneumatic chamber to push the push rod to move upward.

[0014] The top plate is located above the clamping plate, and the deceleration block is made of rubber with a rough surface. When the push rod moves upward, it will drive the deceleration block to move upward and contact the bottom of the top plate. When the rubber deceleration block contacts the bottom of the top plate, it will bring resistance to the movement of the clamping plate.

[0015] The working principle and beneficial effects of the present utility model are as follows:

[0016] 1. By providing an anti-mis-touch clamping mechanism, the present utility model achieves that after pressing the rotating rod leftward and then rotating the rotating rod, the rotating rod will drive the threaded rod B to rotate. The rotation of the threaded rod B drives the two clamping plates to move to clamp the detector body, preventing shaking. After releasing the rotating rod, the rotating rod will move rightward to return to its original position. At this time, rotating the rotating rod can no longer drive the threaded rod B to rotate, achieving the effect of preventing mis-touch and preventing the threaded rod B from rotating due to mis-touch, resulting in the clamping plates loosening the clamping of the detector body.

[0017] 2. By providing an anti-over-clamping mechanism, the present utility model achieves that when the threaded rod B rotates to drive the two clamping plates to move and firmly clamp the detector body, through the cooperation of components such as the airbag, pneumatic chamber, and push rod, it will drive the deceleration block to contact the bottom of the top plate. When the deceleration block contacts the bottom of the top plate, it will bring resistance to the movement of the clamping plate, making it difficult for the threaded rod B to rotate further, thereby preventing over-clamping from causing damage to the detector body.

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present utility model.

[0027] Embodiment 1

[0028] As Figures 1 to 5As shown in the figure, this embodiment proposes a methane remote detection device, which includes a frame 1. A through hole 2 is opened at the inner bottom of the frame 1. A support plate 3 is fixedly connected to the inner side of the frame 1. A detector body 4 is arranged on the top of the support plate 3. A detection tube 5 is arranged at the bottom of the detector body 4. A telescopic tube 6 is slidably connected inside the detection tube 5. A detection head 7 is arranged at the bottom of the telescopic tube 6. The diameter of the through hole 2 is larger than the diameter of the detection head 7. A macroporous adsorption material layer of zeolitic imidazolate framework structure is arranged on the surface of the detection head 7. The detection head 7 can pass through the through hole 2. The macroporous adsorption material layer of zeolitic imidazolate framework structure can increase the signal strength, improve the sensitivity, does not require frequent addition of consumables, is simple to maintain, does not require laser modulation and signal demodulation, has strong anti-interference ability, strong robustness, and a wide range of applications. A chute 8 is opened on the inner side wall of the frame 1. A sliding plate 9 is slidably connected inside the chute 8. The telescopic tube 6 passes through and is fixedly connected to the sliding plate 9. A threaded rod A 10 is rotatably connected inside the chute 8. A motor 11 is arranged on the top of the frame 1. The output shaft of the motor 11 is fixedly connected to the threaded rod A 10. The sliding plate 9 is threadedly connected to the threaded rod A 10. An anti-mis-touch clamping mechanism 12 and an anti-over-clamping mechanism 13 are arranged on the inner side of the frame 1;The anti-misoperation clamping mechanism 12 includes a fixed frame 121 and a rotating rod 126. The fixed frame 121 is fixedly connected to the inner side of the frame 1. A clamping plate 122 is slidably connected to the inner side of the fixed frame 121. A threaded rod B 123 is rotatably connected to the inner side of the fixed frame 121. The number of the clamping plates 122 is set to two groups. The two groups of clamping plates 122 are threadedly connected to the threaded rod B 123 through internal threads, and the internal thread directions of the two groups of clamping plates 122 are opposite. When the threaded rod B 123 rotates, it will drive the two groups of clamping plates 122 to move closer or move away from each other. A groove 124 is formed on the side surface of the threaded rod B 123. A clamping groove 125 is formed on the inner wall of the groove 124. A return spring 1211 is fixedly connected to the inner side wall of the groove 124. One end of the moving block 127 away from the rotating rod 126 is in contact with the return spring 1211 in the initial state. When the moving block 127 moves to the left, it will squeeze the return spring 1211 to make it gradually tense. The rotating rod 126 penetrates through the side surface of the threaded rod B 123. A moving block 127 is fixedly connected to the side surface of the rotating rod 126. A groove 128 is formed on the surface of the moving block 127. A telescopic spring 129 is arranged inside the groove 128. An arc-shaped block 1210 is slidably connected to the inside of the groove 128 through the telescopic spring 129. One end of the arc-shaped block 1210 away from the telescopic spring 129 is in contact with the inner wall of the threaded rod B 123 in the initial state, and the telescopic spring 129 is in a tense state in the initial state. When the telescopic spring 129 rebounds, it will drive the arc-shaped block 1210 to partially pop out of the groove 128. The arc surface of the arc-shaped block 1210 faces the direction of the rotating rod 126. The depth of the groove 128 is greater than the length of the arc-shaped block 1210. When the arc surface of the arc-shaped block 1210 is squeezed, it will move into the groove 128. The arc-shaped block 1210 can be completely retracted into the groove 128. The opening size of the clamping groove 125 is equal to the opening size of the groove 128, and the number of the clamping grooves 125 is set to six groups. The arc-shaped block 1210 can be clamped into the clamping groove 125. When the arc-shaped block 1210 is clamped into the clamping groove 125 and the rotating rod 126 is rotated, the threaded rod B 123 will be driven to rotate through the cooperation of the arc-shaped block 1210 and the clamping groove 125.;

[0029] In this embodiment, when the rotating rod 126 is pressed to the left, the leftward movement of the rotating rod 126 drives the moving block 127 to move leftward, and the return spring 1211 is gradually tightened under extrusion. When the moving block 127 moves leftward so that the groove 128 fits with the clamping groove 125, the telescopic spring 129 rebounds to drive the arc-shaped block 1210 to be stuck into the clamping groove 125. At this time, rotating the rotating rod 126 will drive the threaded rod B123 to rotate through the cooperation between the arc-shaped block 1210 and the clamping groove 125. The rotation of the threaded rod B123 further drives the two groups of clamping plates 122 to move closer to clamp the detector body 4, preventing the detector body 4 from shaking during use. Then, the rotating rod 126 is released. At this time, the rebound of the return spring 1211 will drive the moving block 127 and the rotating rod 126 to move rightward and return to the original position. At this time, the arc surface of the arc-shaped block 1210 will be squeezed and pressed into the groove 128, which will not affect the rightward movement and restoration of the moving block 127 and the rotating rod 126. When the arc-shaped block 1210 leaves the clamping groove 125, rotating the rotating rod 126 will not drive the threaded rod B123 to rotate, effectively achieving the effect of preventing accidental touch, preventing accidental touch from causing the threaded rod B123 to rotate and the clamping plate 122 to loosen the clamping of the detector body 4. And remotely controlling the opening of the motor 11 will drive the threaded rod A10 to rotate. The rotation of the threaded rod A10 drives the slide plate 9 to move up or down to control the retraction or extension of the telescopic tube 6. And the bottom of the telescopic tube 6 is a macroporous adsorption material layer of the imidazole ester skeleton structure, which can increase the signal strength and improve the sensitivity.

[0030] Embodiment 2

[0031] As Figures 1 to 6 shown, based on the same concept as the above Embodiment 1, this embodiment also proposes an anti-over-clamping mechanism 13. The anti-over-clamping mechanism 13 includes a top plate 131 and a pneumatic chamber 132. The top plate 131 is fixedly connected to the inside of the frame 1, and the pneumatic chamber 132 is fixedly connected to the inside of the clamping plate 122. One end of the pneumatic chamber 132 is provided with an airbag 133, and a push rod 134 is slidably connected to the piston inside the other end of the pneumatic chamber 132. The airbag 133 is located on the side of the clamping plate 122 close to the detector body 4. The airbag 133 is in an inflated state in the initial state. When the clamping plate 122 clamps the detector body 4, the airbag 133 will be squeezed by the detector body 4, and the air pressure inside the airbag 133 will enter the pneumatic chamber 132 to push the push rod 134 to move upward. The top of the push rod 134 is fixedly connected with a deceleration block 135. The top plate 131 is located above the clamping plate 122, and the deceleration block 135 is made of rubber material with a rough surface. When the push rod 134 moves upward, it will drive the deceleration block 135 to move upward and contact the bottom of the top plate 131. When the rubber deceleration block 135 contacts the bottom of the top plate 131, it will bring resistance to the movement of the clamping plate 122.

[0032] In this embodiment, based on the above-mentioned Embodiment 1, when the clamping plate 122 clamps the detector body 4, the airbag 133 will be squeezed by the detector body 4. When the clamping plate 122 clamps the detector body 4 tightly, the airbag 133 is completely squeezed and its internal air pressure will enter the air pressure chamber 132 to push the push rod 134 to move upward. The upward movement of the push rod 134 will drive the deceleration block 135 to move upward and contact the bottom of the top plate 131. When the deceleration block 135 made of rubber contacts the bottom of the top plate 131, it will bring resistance to the movement of the clamping plate 122, so that the threaded rod B123 is also difficult to rotate, thus preventing excessive clamping from causing damage to the detector body 4. When the clamping plate 122 releases the clamping of the detector body 4, the airbag 133 rebounds and its internal air pressure returns to the airbag 133, and the push rod 134 drives the deceleration block 135 to move downward and leave the top plate 131.

[0033] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
