Description

A water surface support device for a flow monitoring meter in a mountain gully and its usage method Technical Field

[0001] This invention relates to the field of support equipment technology, and in particular to a water surface support device for a flow monitoring meter in a mountainous ditch and its usage method. Background Technology

[0002] A flow meter consists of two parts: a flow sensor and a converter. It operates based on Faraday's law of electromagnetic induction and is used to measure the volumetric flow rate of conductive liquids with a conductivity greater than 5 μS / cm. It is an inductive instrument for measuring the volumetric flow rate of conductive media.

[0003] The flow meter is mounted on top of a support plate, but the top of the support plate lacks a mechanism to secure the meter during installation. This could cause the meter to fall into water during windy conditions. Furthermore, the flow meter is susceptible to damage from direct sunlight and excessive heat during use. Therefore, to ensure the reliability of the flow meter's installation and use, appropriate support equipment is needed for its installation, and it should be protected from sunlight during use to prevent high-temperature damage. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a water surface support device and a method of use for a flow meter in a mountainous ditch. This support device can be used to reliably clamp and fix the flow meter, effectively preventing it from falling during use; moreover, it can effectively protect it from the sun and cool it down during use, preventing high-temperature damage.

[0005] To achieve the above-mentioned technical features, the present invention aims to provide a water surface support device for a flow monitoring meter in a mountainous ditch, comprising a support plate for supporting the device; a flow monitoring meter for flow monitoring is disposed on the top of the support plate; the flow monitoring meter is clamped and fixed by a clamping mechanism disposed on the top of the support plate; a cooling mechanism for cooling the flow monitoring meter is disposed directly above the flow monitoring meter and on top of the clamping mechanism; and a cleaning mechanism for cleaning the flow monitoring meter is installed on the top of the cooling mechanism.

[0006] The clamping mechanism includes a groove on the top of the support plate, an electromagnetic slide rail installed inside the groove, an electromagnetic slider on the top of the electromagnetic slide rail, a movable plate fixedly mounted on the top of the electromagnetic slider, and a track groove on the top of the movable plate. Slide grooves are provided on both sides of the top of the support plate, and slide bars are slidably mounted inside the slide grooves. One end of the slide bar is located on the top of the movable plate, and a protrusion is fixedly mounted at its bottom. The bottom of the protrusion is located inside the track groove and slidably connected to it. An extension rod is fixedly mounted on the top of the slide bar, and a clamping plate is fixedly mounted on the other end of the extension rod. The clamping plates are located on both sides of the monitoring meter and are used to clamp and fix the monitoring meter.

[0007] There are two sets of track grooves, which are arranged in parallel on the top of the moving plate, and the track grooves all adopt a V-shaped structure.

[0008] The slides are arranged in parallel and symmetrical arrangement on the support plate, and each slide is fitted with a slide bar;

[0009] The extension rod consists of two sets, which are fixed symmetrically on the slide bars on both sides.

[0010] The cooling mechanism includes support bars fixedly installed on both sides of the top of the support plate, and a sunshade net fixedly installed on the inner side of the top of the support bars; a cleaning mechanism for cleaning the sunshade net is installed directly above the sunshade net.

[0011] The cooling mechanism also includes a support frame set on the top of the clamping plate of the clamping mechanism. A turntable is rotatably arranged inside the support frame, and a motor is fixedly installed on the outside of the support frame. A first vertical rod is rotatably arranged on one side of the support frame, and two horizontal rods are fixedly arranged on one side of the first vertical rod. A second vertical rod is fixedly arranged on the inner side of the two horizontal rods. A sliding sleeve is eccentrically fixed on the outer wall of the turntable. The second vertical rod passes through the sliding sleeve and is slidably connected to it. A blade is arranged on one side of the first vertical rod.

[0012] The cleaning mechanism includes a horizontal bar fixed to the top of the support bar, a cylinder fixedly installed in the middle of the horizontal bar, a limit port at the top of the cylinder, a circular opening at the bottom of the cylinder, a placement plate vertically sliding inside the cylinder, a pull rod fixedly installed at the top of the placement plate, clamping rods symmetrically rotating on both sides of the placement plate, a limit block fixedly installed on the inner side of the placement plate and the spring fixedly installed on one side of the placement plate through the support block, and the spring being fixedly connected to the inner side of the clamping rod and used for closing and clamping the two clamps at the bottom of the clamping rod; a counterweight is installed inside the cylinder, an inclined bar is fixedly installed at the top of the support bar, a cylinder is fixedly installed at the top of one end of the inclined bar, and the output end of the cylinder passes through the inclined bar and is fixedly connected to the top of the pull rod.

[0013] The two sides of the bottom of the movable plate are slidably connected to the top of the support plate, and multiple insert rods are fixedly installed at the bottom of the support plate;

[0014] The sun protection net is made of elastic metal material.

[0015] The motor is equipped with a waterproof cover.

[0016] A rotating shaft is fixedly installed on the front surface of the placement plate, and the clamping rod is rotatably connected to the placement plate through the rotating shaft.

[0017] A method for using a water surface support device for a flow monitoring meter in a mountain gully includes the following steps:

[0018] Step 1: Place the monitor between the two clamping plates of the clamping mechanism onto the top of the support plate;

[0019] Step 2: Start the clamping mechanism. Then the electromagnetic slider moves on the electromagnetic slide rail and drives the moving plate to move. Then the protrusion moves inside the track groove. Then the slide bar slides inside the slide groove and drives the extension rod and clamping plate to move. Then the two clamping plates clamp and fix the monitor to the top of the support plate.

[0020] Step 3: During the monitoring process, the monitoring device is protected from damage by high temperatures using a sunshade net.

[0021] Step 4: If the temperature of the monitor is too high, start the cooling mechanism. Then the motor drives the turntable to rotate, the turntable drives the sliding sleeve to rotate, and then the sliding sleeve moves on the second vertical rod, which forces the second vertical rod to rotate, and then drives the first vertical rod and the blade to rotate. When the blade rotates, it generates wind to cool the monitor.

[0022] Step 5: After a period of use, impurities will accumulate on the surface of the sunshade net. Some harmful impurities can reduce the lifespan of the sunshade net, so it is necessary to clean the impurities. At this time, the cylinder is activated, which drives the pull rod and the placement plate to descend inside the cylinder. When the clamping rod descends to the top of the counterweight and contacts its top, the spring is stretched by the opening force at the bottom of the two clamping rods. Then, the top of the counterweight is located between the clamping rods. Then, under the restoring force of the spring, the counterweight is clamped. After that, the cylinder raises the pull rod and the placement plate. When the top of the clamping rod moves into the limit hole, the bottom of the two clamping rods opens, disengaging from the counterweight. Then, the counterweight falls down along the inner wall of the cylinder and falls through the round opening onto the top of the sunshade net. The sunshade net is made of metal elastic material, so it will generate up and down elastic force, thereby cleaning the impurities on the top of the sunshade net.

[0023] The present invention has the following beneficial effects:

[0024] 1. The support device of the present invention can be used to reliably clamp and fix the flow meter, effectively preventing it from falling off during use; moreover, it can effectively protect it from the sun and cool it down during use, preventing high temperature damage.

[0025] 2. Using the clamping mechanism, the device is an electrified body. The monitor is placed on the top of the support plate from the direction of the arrow in Figure 1. Then the electromagnetic slider moves on the electromagnetic slide rail and drives the moving plate to move. Then the protrusion moves inside the track groove. Then the slide bar slides inside the slide groove and drives the extension rod and clamping plate to move. Then the two clamping plates fix the monitor on the top of the support plate.

[0026] 3. The cooling mechanism, with the help of the sunshade net, helps prevent the monitor from being damaged by high temperature. Then the motor drives the turntable to rotate, the turntable drives the sliding sleeve to rotate, and then the sliding sleeve moves on the second vertical rod, which forces the second vertical rod to rotate, and then drives the first vertical rod and the blade to rotate. When the blade rotates, it generates wind force, which helps to cool the monitor.

[0027] 4. The cleaning mechanism addresses the issue of impurities forming on the surface of the sunshade net after a period of use. Some harmful impurities may shorten the net's lifespan, necessitating cleaning. The cylinder activates, causing the pull rod and placement plate to descend inside the cylinder. When the clamping rod descends to the top of the counterweight and contacts it, the bottom of the two clamping rods opens under the action of the spring, and the top of the counterweight is positioned between the clamping rods. The spring then clamps the counterweight. The cylinder then raises the pull rod and placement plate. When the top of the clamping rod moves into the limit opening, the bottom of the two clamping rods opens, and the counterweight falls through the circular opening onto the top of the sunshade net. Since the sunshade net is made of elastic metal, it generates an up-and-down elastic force, which helps clean impurities from the top of the net, thus extending its lifespan.

[0035] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0036] Example 1:

[0037] Please refer to Figures 1-5. A water surface support device for a flow meter in a mountain ditch includes a support plate 1 for supporting the device; a flow meter 12 for flow monitoring is mounted on the top of the support plate 1; the flow meter 12 is clamped and fixed by a clamping mechanism mounted on the top of the support plate 1; a cooling mechanism for cooling the flow meter 12 is mounted directly above the flow meter 12 and on top of the clamping mechanism; and a cleaning mechanism for cleaning the flow meter is mounted on top of the cooling mechanism. This support device reliably clamps and fixes the flow meter, effectively preventing it from falling during use; moreover, it effectively protects the flow meter from the sun and cools it down during use, preventing high-temperature damage. In specific use, the clamping mechanism reliably fixes the flow meter 12 to the top of the support plate 1, thus achieving reliable fixation of the flow meter 12. The cooling mechanism cools the flow meter 12, preventing damage due to high temperatures. The cleaning mechanism effectively cleans the flow meter 12, extending its service life.

[0038] Furthermore, the clamping mechanism includes a groove 2 on the top of the support plate 1, an electromagnetic slide rail 3 installed inside the groove 2, an electromagnetic slider 4 on the top of the electromagnetic slide rail 3, a movable plate 5 fixedly mounted on the top of the electromagnetic slider 4, and a track groove 6 on the top of the movable plate 5. Slide grooves 7 are provided on both sides of the top of the support plate 1, and slide bars 8 are slidably mounted inside the slide grooves 7. One end of the slide bar 8 is located on the top of the movable plate 5, and a protrusion 9 is fixedly mounted on its bottom. The bottom of the protrusion 9 is located inside the track groove 6 and slidably connected to the track groove 6. An extension rod 10 is fixedly mounted on the top of the slide bar 8, and a clamping plate 11 is fixedly mounted on the other end of the extension rod 10. The clamping plates 11 are located on both sides of the monitor 12 and are used to clamp and fix the monitor 12. The above-described clamping mechanism is mainly used to clamp and fix the monitor 12, thereby effectively preventing it from falling off during use. In the specific working process, the electromagnetic slider 4 moves on the electromagnetic slide rail 3, which drives the moving plate 5 to move. Then the protrusion 9 moves inside the track groove 6. After that, the slider 8 slides inside the slide groove 7 and drives the extension rod 10 and the clamping plate 11 to move. Then the two clamping plates 11 clamp and fix the monitor 12 to the top of the support plate 1.

[0039] Furthermore, there are two sets of track grooves 6, arranged in parallel on the top of the moving plate 5, and each track groove 6 adopts a V-shaped structure; the slide grooves 7 are arranged in parallel and symmetrical on the support plate 1, and each slide groove 7 is fitted with a slide bar 8; there are two sets of extension rods 10, fixed in parallel and symmetrical on the slide bars 8 on both sides. By using the above-mentioned track grooves 6, the linear motion of the electromagnetic slide rail 3 and the electromagnetic slider 4 can be converted into a horizontal clamping action, thereby realizing the reliable clamping and fixing of the monitoring meter 12.

[0040] Furthermore, the cooling mechanism includes support bars 13 fixedly installed on both sides of the top of the support plate 1, and a sunshade net 14 fixedly installed on the inner side of the top of the support bars 13; a cleaning mechanism for cleaning the sunshade net 14 is provided directly above it. The cooling mechanism described above achieves a good sun protection and cooling effect. During operation, when the sun is strong, the sunshade net 14 effectively blocks sunlight, thus achieving a good sun protection and cooling purpose.

[0041] Furthermore, the cooling mechanism also includes a support frame 15 mounted on top of the clamping plate 11 of the clamping mechanism. A turntable 16 is rotatably mounted inside the support frame 15, and a motor 17 is fixedly mounted on the outside of the support frame 15. A first vertical rod 18 is rotatably mounted on one side of the support frame 15, and two horizontal rods 19 are fixedly mounted on one side of the first vertical rod 18. A second vertical rod 20 is fixedly mounted on the inner side of the two horizontal rods 19. A sliding sleeve 21 is eccentrically fixed on the outer wall of the turntable 16, and the second vertical rod 20 passes through and is slidably connected to the sliding sleeve 21. A blade 22 is mounted on one side of the first vertical rod 18. This cooling mechanism achieves a fan-like cooling effect. During operation, by activating the cooling mechanism, the motor 17 drives the turntable 16 to rotate, which in turn drives the sliding sleeve 21 to rotate. The sliding sleeve 21 then moves on the second vertical rod 20, forcing the second vertical rod 20 to rotate, which in turn drives the first vertical rod 18 and the blade 22 to rotate. The rotation of the blade 22 generates airflow to cool the monitoring meter 12.

[0042] Preferably, the rotating disk 16, the sliding sleeve 21, and the second vertical rod 20 constitute a crank-slider mechanism, which transmits power to the first vertical rod 18, thereby driving the blade 22 to rotate.

[0043] Furthermore, the cleaning mechanism includes a horizontal bar 23 fixed to the top of the support bar 13, a cylinder 24 fixedly installed in the middle of the horizontal bar 23, a limit port 25 provided at the top of the cylinder 24, a circular opening 26 provided at the bottom of the cylinder 24, a placement plate 27 vertically slidingly installed inside the cylinder 24, a pull rod 28 fixedly installed at the top of the placement plate 27, clamping rods 29 symmetrically rotated on both sides of the placement plate 27, a limit block 30 fixedly installed inside the placement plate 27 and a spring 31 fixedly installed on one side of the placement plate 27 via a support block, one side of the spring 31 being fixedly connected to the inside of the clamping rod 29 and used for closing and clamping the two clamps at the bottom of the clamping rod 29; a counterweight block 32 is installed inside the cylinder 24, an inclined bar 33 is fixedly installed at the top of the support bar 13, a cylinder 34 is fixedly installed at the top of one end of the inclined bar 33, and the output end of the cylinder 34 passes through the inclined bar 33 and is fixedly connected to the top of the pull rod 28. The aforementioned cleaning mechanism facilitates the removal of impurities from the top of the sunshade net 14, thus extending its service life. During the cleaning process, the cylinder 34 activates, causing the pull rod 28 and placement plate 27 to descend inside the cylinder 24. When the clamping rod 29 descends to the top of the counterweight 32 and contacts its top, the spring 31 stretches under the opening force of the two clamping rods 29. The top of the counterweight 32 then lies between the clamping rods 29, and the spring 31 clamps the counterweight 32 under its restoring force. The cylinder 34 then raises the pull rod 28 and placement plate 27. When the top of the clamping rod 29 moves into the limiting port 25, the bottom of the two clamping rods 29 opens, disengaging from the counterweight 32. The counterweight 32 then falls, descending along the inner wall of the cylinder 24 and through the round opening 26 onto the top of the sunshade net 14. Since the sunshade net 14 is made of elastic metal, it generates an up-and-down elastic force, thus cleaning the impurities from the top of the sunshade net 14.

[0044] Furthermore, the two sides of the bottom of the movable plate 5 are laterally slidably connected to the top of the support plate 1, and multiple insert rods are fixedly installed on the bottom of the support plate 1. The movable plate 5 described above can be used to reliably fix and install the entire device.

[0045] Furthermore, the sunshade net 14 is made of a metal elastic material. Because the sunshade net 14 is made of a metal elastic material, it will generate up-and-down elastic force, which helps to clean impurities from the top of the sunshade net 14 and improves its service life.

[0046] Furthermore, a waterproof cover is installed on the outside of the motor 17, which can provide a good waterproof effect for the motor 17.

[0047] Furthermore, a rotating shaft 35 is fixedly provided on the front surface of the placement plate 27, and the clamping rod 29 is rotatably connected to the placement plate 27 via the rotating shaft 35. This rotatable connection ensures that the clamping rod 29 can rotate smoothly.

[0048] Example 2:

[0049] A method for using a water surface support device for a flow monitoring meter in a mountain gully includes the following steps:

[0050] Step 1: Place the monitoring meter 12 from between the two clamping plates 11 of the clamping mechanism onto the top of the support plate 1;

[0051] Step 2: Start the clamping mechanism. Then the electromagnetic slider 4 moves on the electromagnetic slide rail 3 and drives the moving plate 5 to move. Then the protrusion 9 moves inside the track groove 6. Then the slide bar 8 slides inside the slide groove 7 and drives the extension rod 10 and the clamping plate 11 to move. Then the two clamping plates 11 clamp and fix the monitor 12 to the top of the support plate 1.

[0052] Step 3: During the monitoring process, the monitoring device 12 is protected from damage by high temperature by the sunshade net 14;

[0053] Step 4: If the temperature of the monitor 12 is too high, the cooling mechanism is activated. Then the motor 17 drives the turntable 16 to rotate, the turntable 16 drives the sliding sleeve 21 to rotate, and then the sliding sleeve 21 moves on the second vertical rod 20, which forces the second vertical rod 20 to rotate, and then drives the first vertical rod 18 and the blade 22 to rotate. When the blade 22 rotates, it generates wind to cool the monitor 12.

[0054] Step 5: After a period of use, impurities will accumulate on the surface of the sunshade net 14. Some harmful impurities can reduce the lifespan of the sunshade net 14, so it is necessary to clean the impurities. At this time, the cylinder 34 is activated, causing the pull rod 28 and the placement plate 27 to descend inside the cylinder 24. When the clamping rod 29 descends to the top of the counterweight 32 and contacts its top, the spring 31 is stretched under the opening force at the bottom of the two clamping rods 29. Then, the top of the counterweight 32 is located between the clamping rods 29, and then the spring 31... Under the reset force, the counterweight 32 is clamped. Then, the cylinder 34 lifts the pull rod 28 and the placement plate 27. When the top of the clamping rod 29 moves into the limit port 25, the bottom of the two clamping rods 29 opens and disengages from the counterweight 32. Then the counterweight 32 falls down, along the inner wall of the cylinder 24, and falls through the round opening 26 to the top of the sunshade net 14. The sunshade net 14 is made of metal elastic material, so it will generate up and down elastic force, thereby cleaning the impurities on the top of the sunshade net 14.

The sunshade net (14) is made of metal elastic material, so it will generate up and down elastic force. In this way, the impurities on the top of the sunshade net (14) are cleaned.
