Description

Technical Field

[0001] The present invention relates to the technical field of hydrological measurement equipment, and in particular to an intelligent flow measuring device and flow measuring method for an open channel gate. Background Art

[0002] Hydrology refers to various phenomena such as the changes and movements of water in nature. It now generally refers to a marginal discipline that studies the temporal and spatial distribution and changing laws of water in nature. Hydrology belongs to earth science and studies the occurrence, circulation, content, distribution, physical and chemical properties, effects and relationship between water on the earth's surface, in the soil, under the rocks and in the atmosphere and all living things.

[0003] An open channel is a channel with a free surface (all points on the surface are affected by atmospheric pressure). Open channel flow is a flow with a free surface where part of the perimeter of the water flow is in contact with the atmosphere. Since the relative pressure on the free surface is zero, it is also called pressureless flow. When measuring the flow velocity and flow rate of water in an open channel, some measuring equipment is required. An intelligent flow measuring device is one of the detection devices. It detects water flow velocity and flow rate through flow velocity measurement sensors, flow converters and other equipment. For example, the existing public document CN113740553A-A device for measuring the flow velocity of open channel water in irrigation areas discloses a device for measuring flow velocity;

[0004] Although the existing public intelligent flow measuring devices can realize flow measurement operations, there are still certain shortcomings in actual use: first, the existing intelligent flow measuring devices are directly placed inside the channel when in use, and the water flow velocity is detected by the flow velocity measurement sensor. However, when the open channel gate is opened, the open channel water flow velocity is fast, and the water plants, garbage and other debris in the water flow with the rapid flow of the water, which may hit the flow velocity measurement sensor and cause equipment damage. At the same time, the water plants, garbage and other debris attached to the outside of the flow velocity measurement sensor will also affect the measurement accuracy; secondly, the flow velocity measurement sensor in the current intelligent flow measuring device is installed under the lifting part, and this method When the flow velocity measurement sensor needs to be disassembled and maintained, it is not convenient for staff to disassemble and maintain it because the flow velocity measurement sensor is located at the bottom and close to the middle of the open channel, which poses a safety hazard; finally, the existing flow velocity measurement sensor can only change its measurement height according to the channel depth when in use, and can only detect the surface water flow velocity using radar sensors such as ultrasonic waves, and this method cannot adjust the horizontal position of the flow velocity measurement sensor according to the width of the open channel and the gate, affecting the application scope of the intelligent flow measuring device, and cannot detect whether there is an abnormality in the flow at various parts of the open channel; therefore, it is necessary to improve the existing technology to solve the above technical problems. Summary of the invention

[0005] The purpose of this section is to summarize some aspects of embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and the invention title of this application to avoid blurring the purpose of this section, the specification abstract and the invention title, and such simplifications or omissions cannot be used to limit the scope of the present invention.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions: an intelligent flow measuring device for an open channel gate, comprising a supporting mechanism, comprising a supporting plate member installed by fixing bolts on one side of the inner part of the open channel body and a middle connecting rod arranged in the middle position of the inner part thereof, a lifting frame is installed directly below the middle connecting rod, and a through groove is opened on one side of the surface of the lifting frame; and a cutting assembly, comprising a first waterproof shell installed on the surface of the lifting frame and a first motor installed inside the first waterproof shell, the output shaft of the first motor penetrates the bearing on the first waterproof shell and is connected to the first gear plate, a tooth plate is installed on one side of the first gear plate, a limit bar is fixedly connected to the bottom of the tooth plate, a fixed block is fixedly connected to one end of the tooth plate, a first rotating shaft is rotatably connected in the internal bearing of the fixed block, the bottom end of the first rotating shaft penetrates the bearing in the fixed block and is connected to the water wheel, and a cutting knife is detachably installed on the top of the first rotating shaft; wherein the gear on the outer wall of the first gear plate is meshed with the rack on the outer wall of the tooth plate, the cross section of the limit bar is inverted T shape, and the limit bar is slidably connected to the inside of the through groove.

[0011] The beneficial effects of the present invention are as follows: through the cutting assembly, the operation of the first motor can drive the tooth plate to move along the through slot, push the fixed block to move and adjust the distance between it and the flow velocity measuring sensor. At the same time, under the action of the water flow, the water wheel will be continuously driven to rotate, so that the cutting knife on the first rotating shaft can rotate synchronously, which can cut off or divide up and down the water plants, garbage and other debris flowing to the flow velocity measuring sensor, so as to avoid the water flow rate being faster after the gate body is opened, and the water plants, garbage and other debris in the water flowing rapidly with the water flow, and hitting the flow velocity measuring sensor to cause equipment damage, and at the same time, avoid the water plants, garbage and other debris attached to the outside of the flow velocity measuring sensor to affect the measurement accuracy.

[0016] In view of the fact that the existing intelligent flow measuring devices can only change their measuring height according to the channel depth and detect the surface water flow velocity during use, which will affect the application scope of the intelligent flow measuring devices, and cannot detect whether there are abnormalities in the flow at various parts of the open channel, a further improvement of the intelligent flow measuring device for open channel gates is proposed.

[0038] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included. Example 1

[0039] Reference Figure 1 , Figure 2 , Figure 3 and Figure 6 , which is the first embodiment of the present invention, and provides an intelligent flow measuring device for an open channel gate. The intelligent flow measuring device changes the distance between the cutting knife 206 and the flow velocity measurement sensor 108b through the cutting component 200, and at the same time, the cutting knife 206 can be driven to rotate under the action of the water wheel 205 and the first rotating shaft 204a, so as to achieve the purpose of cutting off or dividing the water plants, garbage and other debris flowing to the flow velocity measurement sensor 108b up and down.

[0040] Specifically, it includes a support mechanism 100, including a support plate 104 installed on one side of the inner part of the open channel body by fixing bolts and a middle connecting rod 107 installed in the middle position of the inner part thereof, a lifting frame 108 is installed directly below the middle connecting rod 107, and a through groove 108e is opened on one side of the surface of the lifting frame 108;

[0041] For details, please refer to Figure 3 , Figure 4 , Figure 5 and Figure 7 The slitting assembly 200 comprises a first waterproof shell 201 mounted on the surface of the lifting frame 108 and a first motor 202 mounted inside the first waterproof shell 201. The output shaft of the first motor 202 penetrates the bearing on the first waterproof shell 201 and is connected to the first toothed disc 202a. A toothed plate 203 is mounted on one side of the first toothed disc 202a. The bottom of the toothed plate 203 is fixedly connected to a limiting strip 203a. One end of the toothed plate 203 is fixedly connected to a fixing block 204. A first rotating shaft 204a is rotatably connected to the internal bearing of the fixing block 204. The bottom end of the first rotating shaft 204a penetrates the bearing in the fixing block 204 and is connected to the water wheel 205. A cutting knife 206 is detachably mounted on the top of the first rotating shaft 204a. The gear on the outer wall of the first toothed disc 202a meshes with the rack on the outer wall of the toothed plate 203. The cross section of the limiting strip 203a is inverted T-shaped, and the limiting strip 203a is slidably connected to the inside of the through groove 108e.

[0042] When the above arrangement is in use, the lifting frame 108 and the flow rate measuring sensor 108b installed on its surface are lowered into the supporting mechanism 100, and then the flow rate measuring sensor 108b can be used to detect the speed of the water flow after the gate body 102 is opened, and then the flow converter and controller inside the control box 103a are cooperated to achieve the purpose of water flow measurement. During the detection process of the flow rate measuring sensor 108b placed inside the supporting mechanism 100, the first motor 202 is started, and the output shaft of the first motor 202 rotates to drive the first gear plate 202a to rotate, and the gear on the outer wall of the first gear plate 202a is meshed with the rack on the surface of the side gear plate 203, and the limit strip 203a at the bottom of the gear plate 203 is slidably connected to the inside of the through groove 108e on the surface of the lifting frame 108, so when the first gear plate 202a rotates, it will drive the gear plate 203 to move along the through groove 108e, and the movement of the gear plate 203 will push the fixed block 204 to move and adjust the distance between it and the flow rate measuring sensor 108b, wherein, After the gate body 102 is opened, the water flow will continuously drive the water wheel 205 to rotate, and the first rotating shaft 204a is rotatably connected to the internal bearing of the fixed block 204, and the water wheel 205 and the cutting knife 206 are respectively placed at both ends of the first rotating shaft 204a, so when the water wheel 205 rotates, the cutting knife 206 will be driven to rotate through the first rotating shaft 204a, and the rotation of the cutting knife 206 can cut off or divide the water grass, garbage and other debris flowing to the flow velocity measurement sensor 108b up and down, so as to avoid the gate body 1 After 02 is turned on, the water flows faster, and the aquatic plants, garbage and other debris in the water flow rapidly with the water flow, and hit the flow velocity measurement sensor 108b to cause damage to the equipment. At the same time, it is prevented that the aquatic plants, garbage and other debris are attached to the outside of the flow velocity measurement sensor 108b to affect the measurement accuracy. Among them, the position of the cutting knife 206 away from the flow velocity measurement sensor 108b can be adjusted to reduce the influence of the cutting knife 206 on the water flow velocity. At the same time, the thickness of the cutting knife 206 is relatively thin, which further reduces the influence of the cutting disc on the water flow velocity.

[0043] Furthermore, the supporting mechanism 100 is located inside the open channel body, and both ends of the through groove 108e are opened. The first waterproof shell 201 provides waterproofing and protection for the first motor 202. A gear is provided on the outer wall of the first toothed disc 202a, and a rack is provided on the outer wall of the toothed plate 203, and the gear and the rack are meshed to play a transmission role. The limit bar 203a is slidably connected in the through groove 108e to facilitate the movement and adjustment of the toothed plate 203, and at the same time plays a limiting role. The water wheel 205 and the cutting knife 206 are both located on the first rotating shaft 204a to play a role of synchronous movement.

[0045] Read in detail Figure 4 , Figure 5 and Figure 6 As shown, the outer sides of the left connecting plate 109 and the right connecting plate 1010 are respectively provided with a left slider 105 and a right slider 106, the surfaces of the left slider 105 and the right slider 106 are both installed with a hanging ring 105a, and the other side of the surface of the lifting frame 108 is slidably connected with a flow rate measuring sensor 108b; wherein, the left connecting plate 109 and the right connecting plate 1010 and the left slider 105 and the right slider 106 are respectively symmetrically arranged, the left slider 105 and the right slider 106 are respectively slidably sleeved on the outer walls of the adjacent guide rods 104a, the hanging ring 105a is connected to the lifting mechanism 103b, a slide groove 108a is provided on the other side of the surface of the lifting frame 108, a slide plate 108c is installed at the bottom of the flow rate measuring sensor 108b, and the slide plate 108c is located inside the slide groove 108a, and a limiting portion 108d is installed at a corner of the surface of the lifting frame 108.

[0046] Further, the arch seat 101 is made of cement or metal, the gate body 102, the support mechanism 100, and the opening and closing mechanism 102a are all existing technologies and equipment, so they are not described in detail here. The lifting mechanism 103b, the control box 103a, the flow rate measurement sensor 108b, the limiter 108d, etc. are all technologies in the existing document publication number CN113740553A-A technology used in an open channel water flow rate measurement device for irrigation areas, so they are not described in detail here. The opening and closing mechanism 102a can adjust the opening and closing of the gate body 102, and the lifting mechanism 103b, the control box 103a, the flow rate measurement sensor 108b, the limiter 108d, etc. are all technologies in the existing document publication number CN113740553A-A technology used in an open channel water flow rate measurement device for irrigation areas, so they are not described in detail here. The mechanism 103b can drive the lifting frame 108 and the flow rate measuring sensor 108b to rise and fall and adjust their positions. The flow rate measuring sensor 108b detects the water flow velocity and cooperates with the flow converter in the control box 103a to realize the measurement of the water flow rate. The guide rod 104a plays an auxiliary sliding and limiting role for the left slider 105 and the right slider 106 on both sides. The flow rate measuring sensor 108b is slidably connected to the surface of the lifting frame 108 under the action of the slide plate 108c and the slide groove 108a, and the limiting part 108d plays a limiting role for the flow rate measuring sensor 108b. Example 2

[0047] Reference Figure 5 and Figure 8 , which is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but is different in that, in order to quickly disassemble and maintain the flow rate measurement sensor 108b, the first hand wheel 304a or the second motor 302 is used to flip the lifting frame 108 180 degrees to the upper side to facilitate the operation of the staff and reduce safety hazards.

[0048] Specifically, it also includes an angle adjustment component 300 arranged on the outside of the middle connecting rod 107, the angle adjustment component 300 includes a second waterproof shell 301 installed on the surface of the right connecting plate 1010 and a second motor 302 installed inside the second waterproof shell 301, the output shaft of the second motor 302 passes through the bearing on the second waterproof shell 301 and is connected to the second gear disc 302a; a half gear disc 303 is arranged below the second gear disc 302a, an arc disc 304 is arranged on one side of the half gear disc 303, and a first hand wheel 304a is installed on the outer wall of the arc disc 304; wherein, the gear on the outer wall of the second gear disc 302a is meshed with the gear on the outer wall of the half gear disc 303, the half gear disc 303 and the arc disc 304 are symmetrically arranged, and the half gear disc 303 and the arc disc 304 are both rotatably sleeved on the outer wall of the middle connecting rod 107, and the opposite end faces of the half gear disc 303 and the arc disc 304 are connected to the outer wall of the lifting frame 108 through a connecting plate.

[0049] When the above arrangement is in use, after the flow velocity measuring sensor 108b has been used for a period of time, the staff needs to regularly remove the flow velocity measuring sensor 108b from the water for disassembly and maintenance. When disassembling the flow velocity measuring sensor 108b, the staff can hold the first hand wheel 304a and apply force to it to rotate it, and the rotation of the first hand wheel 304a under force will drive the arc disk 304 to rotate with the middle connecting rod 107 as the center of the circle, wherein the two ends of the lifting frame 108 are respectively connected to the arc disk 304 and the half toothed disk 303 through a connecting plate, and the arc disk 304 and the half toothed disk 303 are both rotatably sleeved on the outer wall of the middle connecting rod 107, so the staff can rotate the first hand wheel 304a to rotate the arc disk 304 with the middle connecting rod 107 as the center of the circle. 04a can drive the lifting frame 108 to flip 180 degrees to the top. When the bank of the open channel body is dangerous and it is inconvenient to manually use the first hand wheel 304a to operate the lifting frame 108, the second motor 302 can be started, and the output shaft of the second motor 302 rotates to drive the second gear disc 302a to rotate. The gear on the outer wall of the second gear disc 302a is meshed with the gear on the outer wall of the half gear disc 303. Therefore, when the second gear disc 302a rotates, it will drive the half gear disc 303 to rotate. The lifting frame 108 can also be flipped 180 degrees to the top, so that the staff can quickly disassemble and maintain the flow measurement sensor 108b, thereby reducing safety hazards.

[0050] Furthermore, the second waterproof shell 301 can provide waterproofing and protection for the second motor 302. The gears on the outer wall of the second toothed disc 302a mesh with the gears on the outer wall of the half toothed disc 303 to play a transmission role. The end faces of both sides of the lifting frame 108 are respectively fixed on the opposite surfaces of the half toothed disc 303 and the arc disc 304 through connecting plates, so that the three can move synchronously and rotate with the middle connecting rod 107 as the center. Example 3

[0051] Reference Figure 4 and Fig. 9 , which is the third embodiment of the present invention, is based on any of the above embodiments, and the difference is that, in order to adjust the horizontal position of the flow velocity measurement sensor 108b, two sets of second hand wheels 403a or two sets of third motors 402 can drive the steel cables 406a on both sides to contract, wind and release, so as to change the horizontal position of the flow velocity measurement sensor 108b, and has a wide range of applications.

[0052] Specifically, it also includes a horizontal adjustment component 400 arranged on the surface of the left slider 105 and the right slider 106, the horizontal adjustment component 400 includes a third waterproof shell 401 installed on the surface of the left slider 105 and the right slider 106, and a third motor 402 installed inside the third waterproof shell 401, a third gear plate 402a is installed on the output shaft of the third motor 402, and a driven gear plate 403 is arranged obliquely below the third gear plate 402a; a second hand wheel 403a is installed on one end surface of the driven gear plate 403, and a second rotating shaft 403b is installed at the center position of the other end surface of the driven gear plate 403 The other end of the second rotating shaft 403b passes through the bearing on the first side plate 404 and is connected to the bearing on the second side plate 405. A winding roller 406 is sleeved on the outer wall of the second rotating shaft 403b, and two groups of steel cables 406a are wound on the outer wall of the winding roller 406; wherein the gear on the outer wall of the third gear plate 402a is meshed with the gear on the outer wall of the driven gear plate 403, and one end of the first side plate 404 and the second side plate 405 is connected to the surface of the adjacent left slider 105 or the right slider 106 through fixing bolts, and the other end of the steel cable 406a is fixed to the outer wall of the adjacent left connecting plate 109 or the right connecting plate 1010.

[0053] When the above arrangement is in use, if it is necessary to use a flow rate measurement sensor 108b to measure the water flow rate of various parts of the support mechanism 100, two staff members can shake the second hand wheels 403a in the horizontal adjustment components 400 on both sides respectively, and the second hand wheels 403a on both sides rotate synchronously in opposite directions. The second hand wheels 403a are forced to drive the driven gear plate 403 to rotate, and the rotation of the driven gear plate 403 will drive the second rotating shaft 403b to rotate, and make the winding roller 406 on the outer wall of the second rotating shaft 403b rotate synchronously, and the reverse rotation of the winding rollers 406 on both sides will synchronously shrink and release the steel cables 406a on both sides. Since the steel cables 406a on both sides are respectively connected to the left connecting plate 109 and the right connecting plate 1010, and the left connecting plate 109 and the right connecting plate 1010 are connected by the middle connecting rod 107, the steel cables 406a on both sides will drive the left connecting plates 109 and 1010 on both sides when they are shrunk, wound and released respectively. The right connecting plate 1010 moves in one direction to change the horizontal position of the lifting frame 108 and the flow rate measuring sensor 108b. When it is inconvenient for the staff to manually operate in wide waters, the third motor 402 in the horizontal adjustment assembly 400 on both sides is started, wherein the third motors 402 on both sides rotate in the opposite direction, and the rotation of the output shaft of the third motor 402 will drive the third gear disc 402a to rotate, and the gear on the outer wall of the third gear disc 402a is engaged with the gear on the outer wall of the driven gear disc 403, so when the third gear disc 402a rotates, it will drive the driven gear disc 403 to rotate, and the rotation of the driven gear disc 403 will drive the corresponding winding roller 406 to rotate, and drive the steel cables 406a on both sides to wind, wind and release, so the length of the steel cables 406a on both sides can be adjusted to achieve the purpose of changing the horizontal position of the flow rate measuring sensor 108b, so that it can be applied to various canals and gates of different widths, and has a wide range of applications.

[0054] Furthermore, the third waterproof shell 401 can provide waterproofing and protection for the third motor 402. The gears on the outer wall of the third gear plate 402a mesh with the gears on the outer wall of the driven gear plate 403 to transmit the power. The winding roller 406 can rotate under the action of the second rotating shaft 403b. By adjusting the length of the steel cables 406a on both sides, the horizontal position of the flow rate measurement sensor 108b can be adjusted. Example 4

[0058] S2: Then, by manual operation or mechanical driving of the third motor 402, the steel cables 406a on both sides are contracted and released synchronously, and the horizontal position of the flow rate measurement sensor 108b on the lifting frame 108 is adjusted by using the change in the length of the steel cables 406a on both sides, so as to measure the water flow at various parts of the support mechanism 100;

[0059] S3: According to S2, the flow rate measuring sensor 108b cooperates with the flow converter in the control box 103a to measure the flow rate when detecting the water flow rate;

[0060] S4: After the water flow velocity and flow rate in the support mechanism 100 are detected, the positions of the flip lifting frame 108 and the flow rate measurement sensor 108b are adjusted by manual operation or mechanical drive of the second motor 302 to facilitate subsequent disassembly and maintenance by the staff.
