Description

Technical Field

[0001] The invention relates to the technical field of soil and water loss monitoring, in particular to a soil and water loss monitoring device for sloping cultivated land. Background Art

[0002] Sloping farmland refers to farmland reclaimed on a terrain with a certain slope. Due to the sloping terrain, this type of land is prone to soil erosion, which has an adverse impact on agricultural production and the ecological environment. Therefore, when carrying out agricultural production on sloping farmland, some special protection measures need to be taken, such as contour farming, terrace construction, vegetation cover, and the establishment of soil and water conservation projects, to reduce soil erosion. In addition, soil erosion monitoring of sloping farmland is also crucial.

[0003] The common soil and water loss monitoring devices on the market are large in size and complicated to deploy. Because sloping farmland is located on mountainous land, the soil and water loss monitoring devices are difficult to install. In addition, the mountainous environment where sloping farmland is located is relatively complex, and the soil and water loss monitoring devices need to be deployed for a long time, which leads to a high damage rate and failure rate of the soil and water loss monitoring devices, making it difficult to achieve stable long-term soil and water loss monitoring.

[0015] Furthermore, the permanent magnet is electromagnetically connected to the armature, and the armature is elastically connected to the second return spring.

[0016] The present invention provides a device for monitoring soil and water loss on sloping farmland, which has the following beneficial effects:

[0017] 1. When the present invention is used, since sloping farmland is usually located in a mountainous environment, when workers are laying out equipment on sloping farmland, the insertion rod can serve as a crutch to assist the workers in moving in the mountainous environment, which can greatly reduce the burden of carrying the equipment. In addition, after the workers arrive at the deployment point of the equipment, they place the insertion rod longitudinally, and then rotate the support head downward to provide auxiliary support, and the downward rotation of the support head can drive the telescopic block to retract, which causes the insertion head in the insertion rod to move down to the soil layer surface due to the loss of locking position. At this time, the worker can rotate the screw pressure seat in the threaded seat and move downward by twisting the gripping handle, and a downward force can be applied to the insertion head during the downward movement of the screw pressure seat, which enables the insertion head to be conveniently and efficiently extended into the soil layer for deployment, and by coordinating with the ease of use of the insertion rod itself, the deployment difficulty of the monitoring device can be greatly reduced.

[0018] 2. The staff of the present invention moves the insertion rod away from the top of the insertion head inserted into the soil layer, and the pressure spring inside the insertion head will drive the extrusion rod to bounce up due to the loss of external pressure, which allows the extrusion rod to extend out of the soil layer. At this time, the staff locks the threaded docking seat at the bottom of the water injection shell with the threaded groove at the top of the extrusion rod, so that the water injection shell and the extrusion rod can be docked. The water injection shell is made of epoxy resin and is lighter when not injected with water, which makes it convenient to carry the water injection shell on sloping farmland. After the water injection shell is docked with the extrusion rod after the water injection is completed, the extrusion rod will squeeze the pressure spring again due to the weight of the water injection shell, and at the same time, this also enables the bottom surface of the water injection shell to be connected with the soil surface of the sloping farmland. Contact, after it rains and causes soil erosion on the sloping farmland, the water injection shell will simultaneously drive the extrusion rod extrusion pressure spring to move downward due to the lowering of the soil layer caused by soil erosion. After the position height of the extrusion rod changes, the tension value of the tension transmission rope between the extrusion rod and the insertion head will change, and the tension sensor can record the tension value and transmit it to the staff regularly through wireless signals. The staff can effectively judge the soil erosion situation of the sloping farmland by recording the tension value transmitted by the tension sensor. Through the above operations, the efficient, fast and convenient deployment of the monitoring device can be guaranteed, and the water injection shell can rely on its own weight to accurately change with the soil layer height, which can effectively ensure the detection accuracy of the equipment.

[0019] 3. After the insertion head of the present invention is laid out, the staff can insert the soil auger at a sloping farmland far away from the insertion head, so that the positioning seat can be laid out on the sloping farmland. At this time, the staff will pull the tension rope in the sealing shell at the top of the laid water injection shell outward, so that the tension rope wound on the winding disk can be gradually pulled out. After the tension rope is pulled out, it can be docked with the docking joint on the docking base inside the positioning seat, so that the tension rope can achieve the connection between the positioning seat and the water injection shell. After the staff tightens the tension rope, the tension rope can be locked by twisting the locking bolt. During the detection process, because the soil auger is locked in the soil layer, the positioning assembly will not change in height as the soil layer height decreases. After the soil layer height at the bottom of the water injection shell decreases due to soil erosion in the sloping farmland, the descent of the water injection shell can make the tension rope align with the The joint generates tension, and the structure of the second spring detection component is consistent with that of the first spring detection component. Through this design, the second spring detection component can also realize the detection of soil erosion status of sloping farmland. Through comparative experimental detection, the detection accuracy of the equipment can be effectively improved. At the same time, this also enables the equipment to still work normally when the first spring detection component or the second spring detection component fails or is damaged, which can improve the detection stability of the equipment. In addition, through the connection of the tension rope, the staff only needs to record the positioning position of the positioning component to realize the positioning of all insertion heads, which can greatly reduce the probability of loss of the monitoring device. In addition, when the tension rope is accidentally pulled by human after the laying is completed, the sliding seat can offset the pulling force by squeezing the first return spring, which can reduce the situation that the tension rope cannot be tightened due to human pulling.

[0030] See also Figures 5 to 8, an insertion assembly 8 is arranged at the outer end of the insertion head 1, and the insertion assembly 8 includes an insertion rod 801, a threaded seat 802, a screw pressure seat 803, a gripping handle 804, a docking seat 805, a rotation support head 806, a permanent magnet 807, an armature 808, a second return spring 809, a pressing head 810, an electric control seat 811, a pressure sensing head 812 and a telescopic stopper 813, a threaded seat 802 is arranged at the top outer end of the insertion rod 801, and a screw pressure seat 803 is connected to the inner side of the threaded seat 802, a gripping handle 804 is arranged at the top outer side of the screw pressure seat 803, docking seats 805 are arranged at both ends of the bottom of the insertion rod 801, and a rotation support head 806 is arranged at the outer end of the docking seat 805, and the rotation A permanent magnet 807 is provided on the side of the support head 806 close to the insertion rod 801, an armature 808 is buried inside the docking seat 805, a second return spring 809 and a pressing head 810 are provided on the side of the armature 808 close to the inner side of the docking seat 805, an electric control seat 811 is arranged inside the docking seat 805, and a pressure sensing head 812 is provided on the side of the electric control seat 811 close to the pressing head 810, and a telescopic stopper 813 is provided on the side of the electric control seat 811 close to the insertion rod 801, the insertion head 1 is arranged in a longitudinal array inside the insertion rod 801, and the telescopic stopper 813 supports the insertion head 1, the permanent magnet 807 is electromagnetically adsorbed and connected to the armature 808, and the armature 808 is elastically connected to the second return spring 809;

[0031] The specific operation is as follows: the staff can rotate the rotating support head 806 to rotate it to a longitudinal position, which makes the adsorption connection between the permanent magnet 807 and the armature 808 be released. After the adsorption between the armature 808 and the permanent magnet 807 is released, the armature 808 will retract into the docking seat 805 due to the resilience of the second return spring 809, which makes the pressing head 810 squeeze the pressure sensing head 812. After the pressure sensing head 812 senses the pressure, it can control the electric control seat 811 to drive the telescopic stopper 813 to retract. At this time, the staff extends the insertion head 1 into the outlet of the insertion rod 801, which can make the insertion head 1 arranged in an array shape inside the insertion rod 801 for placement. After the insertion head 1 is placed, the staff will rotate the rotating support head 806 to a horizontal position, which makes the permanent magnet 807 adsorb the armature 808 again. After the pressing head 810 is separated from the pressure sensing head 812 and cannot sense the pressure, the electric control seat 811 can drive the telescopic stopper 813 to retract. The staff can extend the insertion rod 801 to lock the insertion head 1 inside the insertion rod 801. Because sloping farmland is usually located in a mountainous environment, when the staff deploy equipment on the sloping farmland, the insertion rod 801 can act as a crutch to assist the staff in moving in the mountainous environment, which can greatly reduce the burden of carrying the equipment. In addition, after the staff arrives at the deployment point of the equipment, the insertion rod 801 is placed vertically, and then the rotating support head 806 is rotated downward to provide auxiliary support, and the rotating support head 806 can drive the telescopic stopper 813 to retract when it rotates downward, which makes the insertion head 1 in the insertion rod 801 lose its lock position and move down to the surface of the soil layer. At this time, the staff can rotate the screw pressure seat 803 in the threaded seat 802 and move downward by twisting the gripping handle 804. During the downward movement of the screw pressure seat 803, a downward force can be applied to the insertion head 1, which makes the insertion head 1 conveniently and efficiently extended into the soil layer for deployment. By cooperating with the ease of use of the insertion rod 801 itself, the difficulty of deploying the monitoring device can be greatly reduced.

[0032] See also Figures 1 to 4The first spring detection component 2 includes a pressure spring 201, a tension transmission rope 202 and a tension sensor 203. A pressure spring 201 is arranged between the insertion head 1 and the extrusion rod 3, and a tension transmission rope 202 is connected between the insertion head 1 and the extrusion rod 3. A tension sensor 203 is arranged at the middle end of the tension transmission rope 202. The extrusion rod 3 is fixedly connected to the water injection shell 501 through the locking of the thread groove 4 and the threaded docking seat 504, and the water injection shell 501 applies pressure to the pressure spring 201 through the extrusion rod 3. The sealing shell 505 and the sliding seat 506 are integrated, and the sliding seat 506 is elastically connected to the first reset spring 507. The positioning component 7 includes a positioning seat 701, a soil drill 702, a sealing cover 703, a docking base A base 704, a butt joint 705 and a second spring detection component 706 are provided. A soil drill 702 is provided on the outer side of the bottom of the positioning base 701, and a sealing cover 703 is provided on the outer end of the top of the positioning base 701. A butt base 704 is provided at the middle end of the inner part of the positioning base 701, and a butt joint 705 is arranged inside the butt base 704. A second spring detection component 706 is provided between the butt base 704 and the butt joint 705. The second spring detection component 706 is elastically connected to the butt joint 705, and the structure of the second spring detection component 706 is consistent with the structure of the first spring detection component 2. The butt joint 705 is distributed in a ring shape inside the butt base 704, and the butt joint 705 is fixedly connected to the tension rope 6;

[0033] The specific operation is as follows. After the insertion head 1 is arranged inside the soil layer, the staff rotates the support head 806 horizontally so that the telescopic stopper 813 locks the insertion head 1 inside the insertion rod 801 again. At this time, the staff removes the insertion rod 801 from the top of the insertion head 1 inserted into the soil layer. At this time, the pressure spring 201 inside the insertion head 1 will drive the extrusion rod 3 to bounce up due to the loss of external pressure, which allows the extrusion rod 3 to extend out of the soil layer. At this time, the staff locks the threaded docking seat 504 at the bottom of the water injection shell 501 with the threaded groove 4 at the top of the extrusion rod 3, which can realize the docking of the water injection shell 501 and the extrusion rod 3. The water injection shell 501 is made of epoxy resin and is lighter when not injected with water, which makes the water injection shell 501 convenient to be installed on sloping farmland. When the water injection shell 501 is carried out, after the water injection is completed and docked with the squeezing rod 3, the squeezing rod 3 will squeeze the pressure spring 201 again due to the weight of the water injection shell 501, and at the same time, this also enables the bottom surface of the water injection shell 501 to contact the soil surface of the sloping farmland. After it rains and causes soil erosion in the sloping farmland, the water injection shell 501 will cause the soil layer to drop due to soil erosion and synchronously drive the squeezing rod 3 to squeeze the pressure spring 201 downward. After the height of the squeezing rod 3 changes, the tension value of the tension transmission rope 202 between the squeezing rod 3 and the insertion head 1 will change, and the tension sensor 203 can record the tension value and transmit it to the staff regularly through wireless signals. The staff can effectively judge by recording the tension value transmitted by the tension sensor 203. The above operation can ensure the efficient, fast and convenient deployment of the monitoring device in the case of soil erosion in the sloping farmland, and the water injection shell 501 can accurately change with the height of the soil layer by its own weight, which can effectively ensure the detection accuracy of the equipment. After the insertion head 1 is deployed, the staff can insert the soil drill 702 on the sloping farmland at a farther position from the insertion head 1, so that the positioning seat 701 can be deployed on the sloping farmland. At this time, the staff will pull the tension rope 6 in the sealing shell 505 at the top of the deployed water injection shell 501 outward, so that the tension rope 6 wound on the winding drum 508 can be gradually pulled out, and after the tension rope 6 is pulled out, it can be docked with the docking joint 705 on the docking base 704 inside the positioning seat 701, which makes the tension rope 6 It can realize the connection between the positioning seat 701 and the water injection shell 501. After the staff tightens the tension rope 6, the tension rope 6 can be locked by twisting the locking bolt 509. During the detection process, because the soil drill 702 is locked in the soil layer, the positioning component 7 will not change in height as the soil layer height decreases. After the soil layer height at the bottom of the water injection shell 501 decreases due to soil erosion in sloping farmland, the descent of the water injection shell 501 can cause the tension rope 6 to generate tension on the docking joint 705. The structure of the second spring detection component 706 is consistent with that of the first spring detection component 2. Through this design, the second spring detection component 706 can also realize the detection of soil erosion status in sloping farmland. Through comparative experimental detection, the detection accuracy of the equipment can be effectively improved.At the same time, this also enables the device to work normally when the first spring detection component 2 or the second spring detection component 706 fails or is damaged, which can improve the detection stability of the device. In addition, through the connection of the tension rope 6, the staff only needs to record the positioning position of the positioning component 7 to realize the positioning of all the insertion heads 1, which can greatly reduce the probability of loss of the monitoring device. In addition, when the tension rope 6 is accidentally pulled by human beings after being laid, the sliding seat 506 can offset the pulling force by squeezing the first reset spring 507, which can reduce the situation where the tension rope 6 cannot be tightened due to human pulling.

[0034] In summary, when using the device for monitoring soil erosion on sloping cultivated land, the staff first rotates the rotating support head 806 to make it rotate to a longitudinal position, which releases the adsorption connection between the permanent magnet 807 and the armature 808. After the adsorption between the armature 808 and the permanent magnet 807 is released, the armature 808 will retract into the docking seat 805 due to the rebound force of the second return spring 809, which enables the pressing head 810 to squeeze the pressure sensing head 812. After the pressure sensing head 812 senses the pressure, it can control the electric control seat 811 to drive the telescopic stopper 813 to retract. At this time, the staff inserts the insertion head into the outlet of the insertion rod 801. 1, can make the insertion head 1 be arranged in an array inside the insertion rod 801 for placement. After the insertion head 1 is placed, the staff will rotate the rotating support head 806 to a horizontal position, so that the permanent magnet 807 can re-adsorb the armature 808. After the pressing head 810 is separated from the pressure sensing head 812 and cannot sense the pressure, the electric control seat 811 can drive the telescopic stopper 813 to extend and lock the insertion head 1 inside the insertion rod 801. Because sloping farmland is usually located in a mountainous environment, when the staff deploys equipment on the sloping farmland, the insertion rod 801 can act as a crutch to assist the staff in moving in the mountainous environment, which can greatly reduce the burden of carrying equipment;

[0035] Then, after the staff arrives at the deployment point of the equipment, they place the insertion rod 801 vertically, and then rotate the support head 806 downward to provide auxiliary support, and the downward rotation of the support head 806 can drive the telescopic stopper 813 to retract, so that the insertion head 1 in the insertion rod 801 will lose its lock position and move down to the soil surface. At this time, the staff can rotate the screw pressure seat 803 in the threaded seat 802 and move downward by twisting the gripping handle 804. During the downward movement of the screw pressure seat 803, a downward force can be applied to the insertion head 1, so that the insertion head 1 can be conveniently and efficiently extended into the soil layer for deployment. By coordinating the ease of use of the insertion rod 801 itself, the deployment difficulty of the monitoring device can be greatly reduced.

[0036] After the insertion head 1 is arranged inside the soil layer, the staff member rotates the support head 806 horizontally so that the telescopic stopper 813 locks the insertion head 1 in the insertion rod 801 again. At this time, the staff member removes the insertion rod 801 from the top of the insertion head 1 inserted into the soil layer. At this time, the pressure spring 201 inside the insertion head 1 will drive the extrusion rod 3 to bounce up due to the loss of external pressure, which allows the extrusion rod 3 to extend out of the soil layer. At this time, the staff member locks the threaded docking seat 504 at the bottom end of the water injection shell 501 with the threaded groove 4 at the top end of the extrusion rod 3, so that the water injection shell 501 can be docked with the extrusion rod 3. The water injection shell 501 is made of epoxy resin and is lighter when not injected with water. This makes it convenient to carry the water injection shell 501 on sloping farmland. After the water injection shell 501 is docked with the extrusion rod 3 after the water injection is completed, the extrusion rod 3 will be re-engaged due to the weight of the water injection shell 501. The pressure spring 201 is squeezed for the second time, and at the same time, the bottom surface of the water injection shell 501 can contact the soil surface of the sloping farmland. After the rain causes soil erosion in the sloping farmland, the water injection shell 501 will synchronously drive the squeezing rod 3 to squeeze the pressure spring 201 downward due to the soil erosion causing the soil layer to drop. After the position height of the squeezing rod 3 changes, the tension value of the tension transmission rope 202 between the squeezing rod 3 and the insertion head 1 will change, and the tension sensor 203 can record the tension value and transmit it to the staff regularly through wireless signals. The staff can effectively judge the soil erosion situation of the sloping farmland by recording the tension value transmitted by the tension sensor 203. Through the above operations, the efficient, fast and convenient deployment of the monitoring device can be guaranteed, and the water injection shell 501 can accurately change with the soil layer height by its own weight, which can effectively ensure the detection accuracy of the equipment;

[0037] Then, after the insertion head 1 is laid out, the staff can insert the soil drill 702 on the sloping farmland at a farther position from the insertion head 1, so that the positioning seat 701 can be laid out on the sloping farmland. At this time, the staff will pull the tension rope 6 in the sealing shell 505 at the top of the laid water injection shell 501 outward, so that the tension rope 6 wound on the winding disk 508 can be gradually pulled out. After the tension rope 6 is pulled out, it can be docked with the docking joint 705 on the docking base 704 inside the positioning seat 701, so that the tension rope 6 can achieve the connection between the positioning seat 701 and the water injection shell 501. After the staff tightens the tension rope 6, the tension rope 6 can be locked by twisting the locking bolt 509. During the detection process, because the soil drill 702 is locked in the soil layer, the positioning component 7 will not occur as the soil layer height decreases. Height changes, after the soil layer height at the bottom of the water injection shell 501 drops due to soil erosion on the sloping farmland, the drop of the water injection shell 501 can cause the tension rope 6 to generate tension on the docking joint 705. The structure of the second spring detection component 706 is consistent with the structure of the first spring detection component 2. Through this design, the second spring detection component 706 can also detect the state of soil erosion on the sloping farmland. Through comparative experimental detection, the detection accuracy of the equipment can be effectively improved. At the same time, this also enables the equipment to still work normally when one of the first spring detection component 2 or the second spring detection component 706 fails or is damaged, which can improve the detection stability of the equipment. In addition, through the connection of the tension rope 6, the staff only needs to record the positioning position of the positioning component 7 to realize the positioning of all the insertion heads 1, which can greatly reduce the probability of losing the monitoring device;

[0038] Finally, when the tension rope 6 is accidentally pulled by human beings after being laid out, the sliding seat 506 can offset the pulling force by squeezing the first return spring 507, which can reduce the possibility that the tension rope 6 cannot be tightened due to human pulling.

Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
