Description

Technical Field

[0001] This invention relates to the technical field of arc-shaped gates, and more particularly to an arc-shaped gate liquid level detection device. Background Technology

[0002] An arc-shaped sluice gate is a type of sluice gate used in hydraulic engineering projects, typically for regulating the water level of rivers, reservoirs, or canals. Compared to traditional vertical sluice gates, the arc-shaped sluice gate is characterized by its arc-shaped gate plate, which can better adapt to changes in water pressure and direction. Arc-shaped sluice gates are usually made of metal or concrete, possessing good sealing performance and structural stability, effectively controlling water flow and ensuring the safe operation of hydraulic engineering projects.

[0003] During use, the water level outside the arc gate is constantly changing. When the water level rises too high, the arc gate will be unable to block the water flow, causing the water to flow out from above the arc gate, which can easily cause floods and other disasters. Therefore, it is very important to monitor the water level at the gate at all times. Summary of the Invention

[0004] In view of the problems existing in the prior art, the present invention is proposed.

[0005] Therefore, the purpose of this invention is to provide a liquid level detection device for an arc-shaped gate, the purpose of which is to detect the water level at the arc-shaped gate.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an arc-shaped gate liquid level detection device, comprising,

[0007] The main structure includes a dike, a gate component adapted to be installed inside the dike, and an opening component adapted to be installed outside the gate component.

[0008] The testing mechanism includes a mounting bracket adapted to be installed on the outside of the gate component, a support component adapted to be installed inside the mounting bracket, and a floating component adapted to be installed inside the support component.

[0009] As a preferred embodiment of the arc-shaped gate liquid level detection device of the present invention, the gate component includes an arc-shaped gate disposed inside the embankment, a connecting arm fixedly connected to the outside of the arc-shaped gate, and a support seat fixedly connected to the outside of the embankment.

[0010] The connecting arm is hinged to the support base.

[0011] As a preferred embodiment of the arc-shaped gate liquid level detection device of the present invention, the gate opening component includes a base fixedly connected to the outside of the embankment, and a hydraulic pull rod hinged inside the base.

[0012] The hydraulic tie rod is hinged to the arc-shaped gate.

[0013] In a preferred embodiment of the arc-shaped gate liquid level detection device of the present invention, the supporting component includes a cylinder fixedly connected inside the mounting frame, a straight groove formed inside the cylinder, and a spiral groove formed inside the straight groove.

[0014] As a preferred embodiment of the arc-shaped gate liquid level detection device of the present invention, the supporting component further includes a receiving groove formed inside the cylinder, a first receiving cavity formed inside the cylinder, and a guide groove formed inside the cylinder.

[0015] As a preferred embodiment of the arc-shaped gate liquid level detection device of the present invention, the supporting component further includes a second receiving cavity opened inside the cylinder, and a sliding component adapted to be installed inside the cylinder.

[0016] In a preferred embodiment of the arc-shaped gate liquid level detection device of the present invention, the sliding assembly includes a disk slidably connected inside the first accommodating cavity, a connecting rod fixedly connected to the bottom end of the disk, and a ring fixedly connected to the bottom end of the connecting rod.

[0017] In a preferred embodiment of the arc-shaped gate liquid level detection device of the present invention, the floating component includes a straight rod slidably connected inside the straight groove, an upper floating plate fixedly connected to the bottom end of the straight rod, a flexible sidewall adapted to be installed at the bottom end of the upper floating plate, and a lower floating plate adapted to be installed at the bottom end of the flexible sidewall.

[0018] In a preferred embodiment of the arc-shaped gate liquid level detection device of the present invention, the floating component includes a protrusion fixedly connected to the outside of the straight rod, an air groove formed inside the straight rod, and a through groove formed inside the straight rod.

[0019] In a preferred embodiment of the arc-shaped gate liquid level detection device of the present invention, the floating component includes a groove formed inside the straight rod and a reflector slidably connected inside the groove.

[0020] The beneficial effects of this invention are as follows: Through the cooperation of the supporting components and the floating components, it is possible for the operator to judge the liquid level by observing the height of the rising rod during the gradual rise of the liquid level. When the reflector is pushed out, it can be known that the liquid level is close to the danger level and the gate needs to be opened to release water. By using the gas in the flexible sidewall to push out the reflector, the impact of waves on the raising and lowering of the rod can be effectively reduced. Furthermore, by placing liquid in the first receiving cavity, the impact of waves on the rod can also be reduced. This ensures that the device can only rise when the water surface is relatively stable, thereby ensuring the accuracy of the detection. Attached Figure Description

[0033] Example 1

[0034] Reference Figure 1 , Figure 2 , Figure 6 and Figure 7 The first embodiment of the present invention provides an arc-shaped gate liquid level detection device. The device includes a main body 100, which includes a bank 101, a gate component 102 adapted to be installed inside the bank 101, and an opening component 103 adapted to be installed outside the gate component 102.

[0035] The testing mechanism 200 includes a mounting bracket 201 adapted to be installed on the outside of the gate component 102, a support component 202 adapted to be installed inside the mounting bracket 201, and a floating component 203 adapted to be installed inside the support component 202.

[0036] Specifically, the gate component 102 includes an arc-shaped gate 102a disposed inside the embankment 101, a connecting arm 102b fixedly connected to the outside of the arc-shaped gate 102a, and a support base 102c fixedly connected to the outside of the embankment 101.

[0037] The connecting arm 102b is hinged to the support base 102c.

[0038] Furthermore, the gate opening component 103 includes a base 103a fixedly connected to the outside of the embankment 101, and a hydraulic rod 103b hinged inside the base 103a.

[0039] The hydraulic tie rod 103b is hinged to the arc-shaped gate 102a.

[0040] In use, an arc-shaped gate 102a is installed between the two embankments 101 to block the flow of water. The arc-shaped gate 102a is hinged to the support base 102c via a connecting arm 102b. A base 103a is installed on the outside of the embankment 101. The outside of the base 103a is hinged to the hydraulic tie rod 103b. The hydraulic tie rod 103b is hinged to the arc-shaped gate 102a.

[0041] When flood discharge is required, the hydraulic lever 103b is activated, causing it to pull the arc-shaped gate 102a backward. Under the hinged action of the connecting arm 102b and the support base 102c, the arc-shaped gate 102a rotates backward around the support base 102c, i.e., it is pulled by the attached... Figure 6 Become an appendix Figure 7 The location shown.

[0042] Example 2

[0043] Reference Figures 1-6 This is the second embodiment of the present invention, which differs from the first embodiment in that it provides the working process of the detection mechanism 200.

[0044] Furthermore, the support component 202 includes a cylinder 202a fixedly connected inside the mounting bracket 201, a straight groove 202b opened inside the cylinder 202a, and a spiral groove 202c opened inside the straight groove 202b.

[0045] Furthermore, the support component 202 also includes a receiving groove 202d formed inside the cylinder 202a, a first receiving cavity 202e formed inside the cylinder 202a, and a guide groove 202f formed inside the cylinder 202a.

[0046] The first receiving cavity 202e is filled with liquid.

[0047] Specifically, the support component 202 also includes a second receiving cavity 202g opened inside the cylinder 202a, and a sliding component 202h adapted to be installed inside the cylinder 202a.

[0048] More specifically, the sliding assembly 202h includes a disk 202h-1 slidably connected inside the first receiving cavity 202e, a connecting rod 202h-2 fixedly connected to the bottom end of the disk 202h-1, and a ring 202h-3 fixedly connected to the bottom end of the connecting rod 202h-2.

[0049] The floating component 203 includes a straight rod 203a slidably connected inside the straight groove 202b, an upper floating plate 203b fixedly connected to the bottom end of the straight rod 203a, a flexible sidewall 203c adapted to be installed at the bottom end of the upper floating plate 203b, and a lower floating plate 203d adapted to be installed at the bottom end of the flexible sidewall 203c.

[0050] It should be noted that the floating component 203 includes a protrusion 203e fixedly connected to the outside of the straight rod 203a, an air groove 203f opened inside the straight rod 203a, and a through groove 203g opened inside the straight rod 203a.

[0051] The protrusion 203e is slidably connected inside the spiral groove 202c, so that when the straight rod 203a slides up and down in the straight groove 202b, it will be accompanied by rotational motion.

[0052] Finally, the floating component 203 includes a groove 203h formed inside the straight rod 203a, and a reflector 203i slidably connected inside the groove 203h.

[0053] When in use, air is filled between the upper floating plate 203b, the flexible sidewall 203c and the lower floating plate 203d. Therefore, when the water level gradually rises, the upper floating plate 203b, the flexible sidewall 203c and the lower floating plate 203d will rise with the water surface under the action of buoyancy, thereby driving the straight rod 203a to rotate and rise in the straight channel 202b.

[0054] When the upper surface of the upper float 203b contacts the lower surface of the cylinder 202a, the straight rod 203a has risen to its limit position, and the reflector 203i has completely left the cylinder 202a. If the water level continues to rise at this time, the upper float 203b and the lower float 203d will move closer to each other and squeeze the flexible sidewall 203c, as shown in the attached diagram. Figure 6 As shown, at this time, the gas in the flexible sidewall 203c enters the slide groove 203h through the gas groove 203f and the through groove 203g. Since the reflector 203i completely leaves the cylinder 202a when the straight rod 203a rises to its limit position, the reflector 203i is no longer blocked by the straight groove 202b. Therefore, when the gas enters the slide groove 203h, the reflector 203i is pushed out of the slide groove 203h by the gas, and the lower surface of the reflector 203i abuts against the upper surface of the cylinder 202a, as shown in the attached diagram. Figure 6 As shown. Staff can determine the current water level by observing the length of the extended rod 203a, and when the reflector 203i is pushed out, it indicates that the water level is approaching the danger level and the gate needs to be opened to release water.

[0055] When the straight rod 203a has not fully risen to its limit position, the reflector 203i is still partially inside the straight groove 202b. Due to the obstruction of the straight groove 202b, the reflector 203i cannot be pushed out. Therefore, during the rising process of the straight rod 203a, the upper floating plate 203b and the lower floating plate 203d will not approach each other, that is, the flexible sidewall 203c will not deform.

[0056] It is worth mentioning that the water level is not completely calm. When waves hit the surface of the arc gate 102a, the waves will suddenly lift the lower float 203d. Then, after the water surface calms down, the lower float 203d will descend again. In this case, the actual water level will be lower than the indicated height of the straight rod 203a, which will lead to inaccurate indication.

[0057] In our invention, when a wave suddenly rushes towards the lower float plate 203d, it generates a sudden and enormous compressive force on the gas inside the flexible sidewall 203c. The gas is then suddenly pushed towards the reflector plate 203i through the air groove 203f and the through groove 203g. The side of the reflector plate 203i then violently compresses the inner wall of the straight groove 202b, thereby generating a large frictional force between the reflector plate 203i and the straight groove 202b. This frictional force effectively prevents the straight rod 203a from rising, thus also preventing the lower float plate 203d from rising. Only when the water level rises relatively steadily will the straight rod 203a gradually rise, thereby ensuring the accuracy of the liquid level indication by the straight rod 203a and reducing the impact of the wave on the straight rod 203a.

[0058] Furthermore, when the water level rises to the point where the upper surface of the lower float 203d is close to the cylinder 202a, if another wave crashes against the lower float 203d, the lower float 203d will first squeeze the ring 202h-3, causing the ring 202h-3 to drive the disc 202h-1 to rise via the connecting rod 202h-2. Since the first receiving cavity 202e is filled with liquid, the disc 202h-1 needs to push the liquid from the guide channel 202f into the second receiving cavity 202g to rise. However, since the guide channel 202f is relatively narrow, the liquid cannot pass through the guide channel 202f in a short time. Therefore, the ring 202h-3 and the lower float 203d cannot rise in a short time either, so the wave disappears before the liquid has completely passed through the guide channel 202f.

[0059] In summary, through the cooperation of the supporting component 202 and the floating component 203, the liquid level can be judged by observing the rising height of the straight rod 203a during the gradual rise of the liquid level. When the reflector 203i is pushed out, it can be known that the liquid level is close to the danger level and water needs to be released. By using the gas in the flexible sidewall 203c to push out the reflector 203i, the impact of waves on the rise and fall of the straight rod 203a can be effectively reduced. Furthermore, by placing liquid in the first receiving cavity 202e, the impact of waves on the straight rod 203a can also be reduced. This ensures that the device can only rise when the water surface is relatively stable, thus guaranteeing the accuracy of the detection.

[0060] Example 3

[0061] Reference Figure 1 , Figure 2 , Figure 6 and Figure 7 This is the third embodiment of the present invention, which differs from the second embodiment in that it provides a reset process for the device.

[0062] When in use, the reflector 203i is extended when the liquid level approaches the danger level, as shown in the attached diagram. Figure 6 As shown, at this time, the hydraulic lever 103b needs to be activated to open the gate and release water.

[0063] Under the action of hydraulic lever 103b, the arc-shaped gate 102a rotates to the water discharge position, as shown in the attached diagram. Figure 7 As shown, water will flow out from under the arc-shaped gate 102a at this time.

[0064] After the arc-shaped gate 102a rotates, the detection mechanism 200 also rotates. At this time, the reflector 203i is in an inclined position, as shown in the attached diagram. Figure 7 As shown, under the weight of its own, the reflector 203i will tend to slide into the chute 203h. After the water is released, there is no more water to support the lower float 203d. Under the weight of its own, the lower float 203d will also tend to reset. This causes the gas in the chute 203h to be drawn into the flexible sidewall 203c through the air groove 203f and the through groove 203g. Under the weight of its own and the suction of the gas, the reflector 203i will slide back into the chute 203h. The lower surface of the reflector 203i will no longer press against the cylinder 202a. Under the weight of its own, the floating component 203 will descend to its initial position. After the water is released, the hydraulic lever 103b is activated to close the arc gate 102a again, thus completing the reset of the entire device.
