Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to an electromagnetic limiting type water conservancy gate. Background Art

[0002] Due to the limitations of the specific application environment, a hydraulic gate needs to be equipped with a limit structure to limit the stroke. As shown in a gate position limiting device for a hydraulic gate with application number CN202221003703.6, in order to ensure the normal use of the limit switch and prevent it from being affected by the external environment, our company previously set it in the control electrical box and triggered it through a trigger rod that passes through the top beam. This method can normally complete the travel range limitation of the blocking plate, but there are many structural parts and the cost is high. In addition, a large space needs to be reserved in the control electrical box for setting related structural parts, and the setting process is relatively complicated. Utility Model Content

[0003] In order to solve the problem that the above-mentioned method of setting a through trigger rod to assist in limiting the stroke is too complicated, the utility model provides an electromagnetic limit type hydraulic gate.

[0004] The technical solution of this utility model is as follows:

[0005] An electromagnetic limited hydraulic gate comprises vertical beams arranged at intervals in the horizontal direction, a top beam and a bottom beam are respectively arranged at both ends of the vertical beam, and a blocking plate is arranged between the vertical beams, and a control assembly is arranged above the top beam to be connected with the blocking plate and can drive the blocking plate to rise and fall;

[0006] Any vertical beam is provided with two limiters at intervals along the length direction, and the limiter includes a waterproof shell and a magnetic switch arranged inside the shell. The blocking plate is provided with a trigger member arranged opposite to the limiter, and the trigger member does not contact the magnetic switch and can trigger the magnetic switch.

[0007] Different from the existing method of setting a trigger rod to assist in triggering, this structure adopts a magnetic triggering method, so it can complete the limit of the stroke in a non-contact situation, and then the electrical components can be set in the waterproof shell and ensure their isolation from the external environment.

[0008] In order to change the limit stroke, the position of the stopper in the length direction of the vertical beam can be adjusted. The limit stroke can be adjusted according to needs to meet various needs.

[0009] As a preferred solution, there is only one stopper arranged at the end of the vertical beam close to the top beam. The above method can shorten the length of the vertical beam as much as possible and thus save costs.

[0010] In order to completely cut off the water flow, one and only one stopper can be triggered when the blocking plate contacts the bottom beam.

[0011] The specific structure of the trigger member is that the trigger member includes a trigger block capable of triggering the magnetic switch, the trigger block is connected to the blocking plate through an extended mounting plate, and the trigger block is arranged higher than the blocking plate. The above method can ensure that the trigger block and the magnetic switch are arranged at a higher position without being limited by the setting range of the blocking plate.

[0012] In order to ensure the accuracy of the travel limit, the trigger block is made of magnetic material, and the blocking plate and the extended mounting plate are made of non-magnetic material, so as to prevent the blocking plate and the extended mounting plate from triggering the magnetic switch.

[0013] As a preferred solution, the horizontal distance between the trigger block and the magnetic switch can be adjusted. After the magnetism of the trigger block is reduced, the trigger block can be pressed against the magnetic switch to ensure the triggering effect.

[0014] The specific structure of the above control assembly is that the control assembly is connected to the blocking plate through a driving rod, and the driving rod and the blocking plate are connected through threads, and the control assembly includes a control electrical box for controlling the rotation of the driving rod.

[0015] In order to realize manual driving, the driving rod passes through the control box and is connected with a rotating handle.

[0016] As a preferred solution, the control electrical box is also connected to a solar panel.

[0017] The beneficial effect of the utility model is that the utility model is an electromagnetic limit type water conservancy gate. Different from the stroke limitation method previously selected by the company, the device adopts a magnetic switch for stroke limitation. Since the magnetic switch does not require direct contact, it can be set in a waterproof shell for protection. After that, only a trigger block needs to be set to complete its triggering. Therefore, the trigger block can be set at the corresponding position according to needs, and the height and horizontal positions can be customized according to needs. Compared with existing equipment, it has lower costs and fewer structural parts. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] like Figure 1 An electromagnetic limited hydraulic gate is shown, comprising a vertical beam 1 arranged at intervals in the horizontal direction, the vertical beam 1 is arranged vertically, and when necessary, it needs to be connected to the side wall of the canal, and the interval length determines the width of the gate, and then a top beam 3 and a bottom beam 2 are respectively arranged at both ends of the vertical beam 1, wherein the top beam 3 is used to set the driving mechanism, and the bottom beam 2 is used to connect to the ground of the canal, and needs to contact with the blocking plate and realize the cutoff of the water flow, and then a blocking plate 4 can be arranged between the vertical beams 1, and the two sides of the blocking plate 4 are movably connected to the vertical beam 1 and can be moved. When in use, it can ensure that the water flow is blocked while being able to move, and when the blocking plate 4 is raised to produce a height difference with the bottom beam 2, it can be used to control the opening size, finally, a control assembly 6 is arranged above the top beam 3 and connected to the blocking plate 4, and can drive the blocking plate 4 to rise and fall, the above structure is the overall frame structure of the hydraulic gate, and the principle is no longer repeated, because the way to control the opening is to control the height of the blocking plate 4, it is necessary to limit the movement of the blocking plate 4 within a certain height to ensure that the equipment can be used normally.

[0027] In response to the above-mentioned needs, a limit structure needs to be set for the hydraulic gate. As shown in the patent mentioned in the background technology, in order to prevent the limit switch from contacting the water flow, the limit switch is set in the control assembly 6, and then the trigger rod can be used to assist in positioning and triggering. However, it can be seen from the structure introduced in the above patent that there are many structural parts and it is also more laborious to install. In response to this, our company has proposed a new limit method to replace the original limit method, and the effect is not affected.

[0028] like Figure 1-4As shown, the new method is that any vertical beam 1 is provided with two limiters 7 at intervals along the length direction, and the length direction is a vertical plane, so that the blocking plate 4 can be limited to move within a certain height range, and the specific structure of the above-mentioned limiter 7 is, including a waterproof shell 71 and a magnetic switch 72 arranged inside thereof. Since the triggering of the magnetic switch 72 does not require direct contact, it can be set in a sealed structure and waterproof, instead of being triggered by resistance like the existing travel switch. Therefore, it is not necessary to consider the waterproof problem of the equipment when setting it. Compared with purchasing a travel switch with high waterproof performance, its cost is also lower, and the setting position does not need to consider waterproofing and other issues. Due to the existence of the waterproof shell 71, it can be set at any position. At the same time, in order to trigger, the blocking plate 4 is provided with a trigger member 8 arranged opposite to the limiter 7, and the trigger member 8 does not contact the magnetic switch 72 and can trigger the magnetic switch 72, so the trigger member 8 needs to adopt a magnetic structure.

[0029] like Figure 2 As shown, the specific structure of the trigger member 8 is that the trigger member 8 includes a trigger block 82 capable of triggering the magnetic switch 72, and the trigger block 82 is connected to the blocking plate through an extended mounting plate 81. By extending the mounting plate 81, the installation position will not be limited to the interval where the blocking plate 4 is located, but the trigger block 82 can be set and applied in more positions, so the trigger block 82 can be set higher than the blocking plate 4. The purpose is to ensure that the trigger block 82 and the magnetic switch 72 are set at a higher position without being limited to the setting interval of the blocking plate 4 by adopting the above method, thereby avoiding immersion in water. Although the waterproof shell can be waterproof, it does not mean that the house needs to be directly set underwater. The best setting position is still to be set in a better environmental position.

[0030] It should be noted that in the above structure, in order to ensure the accuracy of the travel limit, the trigger block 82 is made of magnetic material, and the blocking plate 4 and the extended mounting plate 81 are made of non-magnetic material. Avoid the blocking plate 4 extending the mounting plate 81 to trigger the magnetic switch 72. Ensuring that the trigger block 82 triggers the magnetic switch 72 can ensure accurate positioning of the limit position.

[0031] Since the magnetism of the magnetic structure is different, the horizontal distance between the trigger block 82 and the magnetic switch 72 can be adjusted. After the magnetism of the trigger block 82 is reduced, the trigger block 82 can be close to the magnetic switch 72 to ensure the triggering effect.

[0032] The above structure can be used to achieve that, different from the existing method of setting a trigger rod to assist in triggering, this structure adopts a magnetic triggering method, so that the travel limit can be completed in a non-contact situation, and the electrical components can be set in the waterproof shell 71 and ensure that they are isolated from the external environment. Therefore, it is not limited by the setting environment, and the position can be freely selected according to the needs, and there is no need to set a trigger rod to assist in triggering.

[0033] In addition to the above structure, in order to change the limit stroke, the position of the limiter 7 in the length direction of the vertical beam 1 can be adjusted. The limit stroke can be adjusted according to needs to meet various needs. The waterproof shell is fixed to the vertical beam 1 by bolts, and the above function can be achieved by opening multiple fixing holes in the vertical beam 1 along the height direction.

[0034] It should be noted that in the above structure, as a preferred solution, there is only one stopper 7 set at the end of the vertical beam 1 close to the top beam 3. The above method can shorten the length of the vertical beam 1 as much as possible to save costs. If the distance between the stopper 7 and the top beam 3 is too large, the vertical beam 1 will have no effect between the stopper 7 and the upper part. If there is no need to adjust the stroke, you can directly choose to shorten this distance.

[0035] It should be noted that, in order to completely cut off the water flow, one and only one stopper 7 can be triggered when the blocking plate 4 contacts the bottom beam 2 .

[0036] For the above structure, multiple driving modes can be selected, and this structure is not the focus of this patent. Therefore, one is selected. The specific structure of the above control assembly 6 is that the control assembly 6 is connected to the blocking plate 4 through the driving rod 5, and the driving rod 5 and the blocking plate are connected by threads. The control assembly 6 includes a control box 61 for controlling the rotation of the driving rod 5. Correspondingly, in order to realize manual drive, the driving rod 5 passes through the control box 61 and is connected with a rotating handle 62.

[0037] Finally, in order to reduce the charging frequency, the control power box 61 is also connected to a solar panel 63 .
