Description

Technical Field

[0001] This utility model relates to the field of ignition point detection technology, and in particular to a plant ignition point detection device. Background Technology

[0002] The ignition point of plants, as a key parameter for measuring the flammability of plants, is of great significance in forest fire prevention, ecological protection, agricultural production and biomass energy development. It refers to the lowest temperature at which plants will burn under specific conditions and is directly related to fire risk assessment, vegetation fire prevention planning and the safe utilization of biomass materials.

[0003] The plant sample to be tested for ignition point is held horizontally, and the flame at the bottom is adjusted to the bottom of the plant sample. The height of the flame inside the sample is adjusted so that the flame temperature is different, and the ignition point of the sample is determined.

[0004] Existing plant ignition point detection devices can only detect plant samples that are in a straight line. When detecting non-linear samples, the clamping components are quite strained, making it difficult to adjust the rotation angle of the clamps and the distance between the two clamps. Therefore, a new plant ignition point detection device is proposed. Utility Model Content

Insert rods adapted for use with the mounting plate are symmetrically arranged on one side of the cross slider. Adjustment mechanism; the mechanism is located inside the clamping mechanism, the adjustment mechanism includes symmetrically arranged circular seats, and a deep groove is installed on one side of the circular seats.

[0007] In a preferred embodiment of the plant ignition point detection device of this utility model, the two clamps are movably connected to the mounting plate and the cross slider, respectively. The mounting plate has a cross groove on one side that is adapted to the cross slider. The inner surface of the cross groove has a plurality of insertion holes that are evenly distributed and symmetrically opened to be adapted to the insertion rod. The insertion rod is movably inserted into the insertion hole.

[0008] In a preferred embodiment of the plant ignition point detection device of this utility model, the cross slider, the side plate and the cross slider are symmetrically mounted with fixing plates on the same side, the outer surface of the insertion rod is equipped with a limit ring, a first spring is provided on one side of the limit ring, and a pull plate is installed on one side of the insertion rod.

[0009] In a preferred embodiment of the plant ignition point detection device of this utility model, the top of the fixing plate is symmetrically provided with sliding holes adapted to the insertion rod, the insertion rod is slidably connected inside the sliding holes, the first spring is located outside the insertion rod, and the limiting ring and the first spring are located on opposite sides of the two fixing plates.

The deep groove is rotatably connected to the round seat inside the T-shaped groove, and a plurality of round holes are distributed circumferentially on the inner surface of the T-shaped groove.

[0011] In a preferred embodiment of the plant ignition point detection device of this utility model, a plurality of top beads are arranged circumferentially on the outer surface of the circular seat, a second spring is provided on one side of the top bead, and a plurality of arc grooves adapted to the top beads are arranged circumferentially on the outer surface of the circular seat. The top beads are movably engaged in the arc grooves and slidably connected in the circular hole.

[0012] (III) Beneficial Effects This invention provides a plant ignition point detection device. It has the following beneficial effects: 1. The clamping mechanism allows adjustment of the distance between the two clamps to accommodate plant combustion samples of different lengths. Pulling the two rods outwards via the pull plate removes them from the mounting plate. Manually moving the cross slider inwards moves one side of the clamp, adjusting the distance between the two clamps to fit different lengths of combustion samples. Removing the pull force from the pull plate allows the two first springs to push the rods inwards through the limiting ring, thus adjusting the distance between the two clamps and accommodating more plant combustion samples, improving the device's adaptability.

[0013] 2. The adjustment mechanism allows for adjustment of the clamp's rotation angle to accommodate plant samples for non-linear combustion tests. After manually rotating the clamp around the deep groove, the second spring pushes the corresponding top bead towards the round seat, restricting the rotation of the round seat and thus fixing the clamp at the rotated angle. This allows for quick adjustment of the clamp angle, accommodating a wider range of plant sample combustion tests. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Example 1 Reference Figure 1 , Figure 2 and Figure 3 This is the first embodiment of the present invention, which provides a plant ignition point detection device, comprising: Box 1; a guide rail 5 is provided at the bottom of the inner cavity of box 1, a combustion seat 6 is installed on the top of the guide rail 5, a lifting component is provided at the rear of box 1, and clamps 4 are symmetrically arranged in the inner cavity of box 1. The clamping mechanism 2 is located on one side of the lifting component. The clamping mechanism 2 includes a mounting plate 201 installed on one side of the lifting component. A cross slider 202 adapted for use with the clamp 4 is movably installed inside the mounting plate 201. Insert rods 204 adapted for use with the mounting plate 201 are symmetrically arranged on one side of the cross slider 202.

[0023] Specifically, the two clamps 4 are movably connected to the mounting plate 201 and the cross slider 202, respectively. The mounting plate 201 has a cross groove on one side that is adapted to the cross slider 202. The inner surface of the cross groove has several equally distributed and symmetrically arranged insertion holes that are adapted to the insertion rod 204. The insertion rod 204 is movably inserted into the insertion hole. Under the action of the cross groove, the cross slider 202 is kept stable when it moves, and the distance between the two clamps 4 can be adjusted.

[0024] Specifically, a side plate 203 is installed on one side of the cross slider 202, and a fixing plate 206 is symmetrically installed on the same side as the side plate 203 and the cross slider 202. A limit ring 207 is installed on the outer surface of the insertion rod 204. A first spring 208 is provided on one side of the limit ring 207, and a pull plate 205 is installed on one side of the insertion rod 204. Under the action of the first spring 208, a downward pushing force is applied to the limit ring 207. With the assistance of the limit ring 207, the insertion rod 204 is stabilized in the corresponding insertion hole of the mounting plate 201.

[0025] Specifically, the top of the fixing plate 206 is symmetrically provided with sliding holes that are adapted to the insertion rod 204. The insertion rod 204 is slidably connected inside the sliding holes. The first spring 208 is located on the outside of the insertion rod 204. The limiting ring 207 and the first spring 208 are located on opposite sides of the two fixing plates 206. Under the action of the two fixing plates 206, the insertion rod 204 can move up and down stably without deviation during the up and down movement.

[0026] Furthermore, the lifting component is a conventional lifting method well known to those skilled in the art. A motor drives a lead screw to move the mounting plate 201 up and down. Specific parameters such as lead and speed can be selected according to actual needs. Manually pulling the pull plate 205 outwards causes the two insert rods 204 to move outwards. The insert rods 204 apply tension to the limiting ring 207. With the assistance of the fixing plate 206, the two first springs 208 are compressed, causing the first springs 208 to deform and move the two insert rods... After the rod 204 is pulled out from the mounting plate 201, the cross slider 202 is pushed towards the center of the mounting plate 201. The cross slider 202 drives the clamp 4 on one side to move, and the distance between the two clamps 4 is adjusted. After the distance between the two clamps 4 is adjusted, the pulling force applied to the pull plate 205 is removed. Under the action of the two first springs 208, pressure is applied to the limiting ring 207. The limiting ring 207 pushes the rod 204 into the mounting plate 201, thus fixing the cross slider 202 in that position.

[0027] Example 2 Reference Figure 4 and Figure 5 This is the second embodiment of the present invention, which is based on the previous embodiment. The adjustment mechanism 3 is placed inside the clamping mechanism 2. The adjustment mechanism 3 includes symmetrically arranged circular seats 301, and a deep groove 305 is installed on one side of the circular seats 301.

[0028] Specifically, the mounting plate 201 and the cross slider 202 are both provided with T-shaped grooves on the same side to be used with the round seat 301. The deep groove 305 is rotatably connected to the round seat 301 inside the T-shaped groove. Several round holes 304 are distributed around the inner surface of the T-shaped groove. When the clamp 4 is rotated around the deep groove 305 at a certain angle, the deep groove 305 can be rotated stably with the assistance of the round seat 301.

[0029] Specifically, a number of top beads 303 are distributed circumferentially on the outer surface of the round base 301. A second spring 302 is provided on one side of each top bead 303. A number of arc grooves adapted to the top beads 303 are distributed circumferentially on the outer surface of the round base 301. The top beads 303 are movably engaged in the arc grooves and slidably connected in the round hole 304. Under the action of the second spring 302, a pushing force is applied to the round hole 304 in the direction of the round base 301, so that the top beads 303 are stably engaged in the round base 301, fixing the round base 301 in the rotated position.

[0030] Furthermore, the clamp 4 is manually rotated around the deep groove 305. The deep groove 305 drives the round seat 301 to rotate. During the rotation of the round seat 301, the round seat 301 pushes the top bead 303 into the inner cavity of the round hole 304, causing the second spring 302 to deform under pressure. During the rotation of the round seat 301, the top bead 303 alternately enters the next slot of the round seat 301. After the clamp 4 is rotated to the correct angle, under the action of several second springs 302, a pushing force is applied to the top bead 303 in the direction of the round seat 301, fixing the round seat 301 in the rotated position. Thus, the clamp 4 can be fixed at this angle position. The non-linear plant sample is clamped in the two clamps 4, and the ignition point of the sample can be detected.

[0031] Working principle: Manually pull the pull plate 205 outwards. The pull plate 205 drives the two insert rods 204 to move outwards. The insert rods 204 apply a pulling force to the limiting ring 207. With the assistance of the fixing plate 206, the two first springs 208 are compressed. The first springs 208 deform and pull the two insert rods 204 out of the mounting plate 201. Then, the cross slider 202 is pushed towards the center of the mounting plate 201. The cross slider 202 drives the clamp 4 on one side to move, adjusting the distance between the two clamps 4. After the distance between the two clamps 4 is adjusted, the pulling force applied to the pull plate 205 is released. Under the action of the two first springs 208, pressure is applied to the limiting ring 207. The limiting ring 207 pushes the insert rods 204 into the mounting plate 201, thus fixing the cross slider 202 in that position. The plant combustion sample is fixed in the inner cavity of the box 1 using the clamp 4. The combustion seat 6 is adjusted to match the ignition via the guide rail 5. At the bottom of the sample, ignite the combustion seat 6, and use the lifting component to adjust the height of the mounting plate 201, thereby adjusting the height of the flame in the sample. The detection data can be obtained through the control cabinet on one side of the box 1. When it is necessary to detect the ignition point of non-linear plant samples, manually rotate the clamp 4 around the deep groove 305. The deep groove 305 drives the round seat 301 to rotate. During the rotation of the round seat 301, the round seat 301 pushes the top bead 303 into the inner cavity of the round hole 304, causing the second spring 302 to deform under pressure. During the rotation of the round seat 301, the top bead 303 alternately enters the next round seat 301 slot. After the angle of the clamp 4 is rotated, under the action of several second springs 302, a pushing force is applied to the top bead 303 in the direction of the round seat 301, fixing the round seat 301 in the rotated position. The clamp 4 can then be fixed in this angle position, and the non-linear plant sample can be clamped in the two clamps 4 for ignition point detection.
