Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water conservancy engineering equipment, in particular to a water conservancy gate with opening position measurement function. Background Art
[0002] The maximum stroke of a hydraulic gate can be limited by setting a limiter. However, in some cases, the hydraulic gate does not need to be fully opened or closed, and needs to be moved to a fixed height as required to obtain the required opening height. Therefore, the existing hydraulic gate will connect an encoder to the motor that drives the gate plate to rise and fall, and obtain the number of motor rotations through the above method, so as to understand the number of rotations of the screw rod and the relative position of the gate plate to the screw rod at the same time. The above method can control the lifting position of the gate plate by recording the number of rotations of the motor, but the disadvantage is that the price of the encoder is relatively high, resulting in high equipment costs. If a lower-priced encoder is replaced, its product quality will be difficult to guarantee. Utility Model Content
[0003] In order to solve the problem of high cost in the above-mentioned method of using an encoder to record the gate height, the utility model provides a hydraulic gate with opening position measurement.
[0004] The technical solution of this utility model is as follows:
[0005] A hydraulic gate with opening position measurement, comprising an assembly frame, a gate plate movable in a vertical direction is arranged inside the assembly frame, a lifting screw rod is arranged through the assembly frame in a vertical direction, and the lifting screw rod is connected to the gate plate through a screw rod seat;
[0006] The lifting screw rod is connected to an electric drive and / or a manual drive above the assembly frame;
[0007] The lifting screw is also connected to a counter, which includes a proximity switch and a trigger member that are relatively arranged, and the proximity switch is located on one side of the lifting screw and is fixed in position. The trigger member is relatively fixed to the lifting screw and can rotate synchronously.
[0008] Different from the method of setting an encoder, this device can record the number of rotations of the lifting screw by setting a proximity switch, thereby controlling the height position of the gate. Compared with the encoder, the price of the proximity switch is lower, and the cost of the trigger component can be basically ignored.
[0009] In order to improve the monitoring accuracy, the triggering member is arranged in a plurality of directions around the central axis of the lifting screw rod. If only one triggering member is arranged, only the number of turns can be recorded, but if more triggering members are arranged, the specific rotation angle of one turn of the lifting screw rod can be controlled with higher accuracy.
[0010] In order to ensure the accuracy of recorded information, a plurality of proximity switches are arranged along the rotation path of the trigger member, thereby avoiding failure of a single proximity switch, improving accuracy and counting frequency division.
[0011] In order to ensure that the triggering members can trigger all the proximity switches simultaneously, the number of triggering members is a positive integer multiple of the number of proximity switches, and within the same time period, all proximity switches can be aligned with adjacent triggering members.
[0012] For easy installation and use, all trigger parts are located on the same horizontal plane, and all proximity switches are located on the same horizontal plane.
[0013] In order to facilitate the replacement of the proximity switch, the proximity switch is fixed to the electric drive via a reference plate and can be disassembled.
[0014] In order to facilitate the adjustment of the position of the proximity switch according to needs, the proximity switch is fixed to the reference plate through a waist-shaped hole, and the position can be adjusted.
[0015] The trigger member is connected to the lifting screw rod in such a manner that the lifting screw rod is sleeved with a synchronous seat, and the trigger member is arranged on a side of the synchronous seat facing the proximity switch.
[0016] As a preferred solution, the synchronous seat is made of non-metallic material, and the trigger is made of metal material, so as to avoid the influence of the synchronous seat on the use of the proximity switch.
[0017] In order to adjust the position of the trigger member, the fixed position of the synchronous seat relative to the lifting screw rod can be adjusted. Adjusting the synchronous seat can adjust all the trigger members at the same time to avoid the occurrence of a single trigger member position misalignment.
[0018] The beneficial effects of the utility model are as follows: the utility model is a hydraulic gate with opening position measurement, which utilizes a combination of a proximity switch and a trigger member to replace the original encoder structure, and can also realize the recording of the number of rotations of the lifting screw, and by increasing the trigger member, the above-mentioned recording accuracy can be improved, and the number of proximity switches can be increased synchronously, which can ensure the accuracy of the counting, and in the event of a problem with a single proximity switch, the other proximity switch can still be used normally, which is more flexible in setting than the encoder and has lower cost.

[0026] 1. Assembly frame; 2. Gate; 3. Lifting screw; 4. Electric drive; 5. Counter; 51. Reference plate; 52. Proximity switch; 53. Synchronous seat; 54. Trigger; 6. Manual drive; 7. Photovoltaic panel. DETAILED DESCRIPTION
[0027] like Figure 1 , 2 A hydraulic gate with opening position measurement shown in the figure includes an assembly frame 1, and a gate plate 2 that can move in the vertical direction is arranged on the inner side of the assembly frame 1. The water flow can be controlled by controlling the lifting and lowering of the gate plate 2. The above structure is a conventional design, so it is not repeated. In the above structure, the method for driving the gate plate 2 to be lifted and lowered is that the assembly frame 1 is penetrated by a lifting screw rod 3 in the vertical direction, and the lifting screw rod 3 is connected to the gate plate 2 through a screw rod seat. Since there are many ways to drive the gate plate 2 to be lifted and lowered, but the present device is only applicable to the screw rod driving method, other driving structures are not repeated, and only a specific introduction is made to the application of this screw rod driving method.
[0028] It should be noted that the present device is not limited to manual drive or electric drive, and any drive method that drives the screw rod to rotate is acceptable. For this purpose, the lifting screw rod 3 is connected to an electric drive 4 and / or a manual drive 6 above the assembly frame 1. One or both of them can be selected according to needs.
[0029] Afterwards, if Figure 3 , 4As shown, the lifting screw 3 is also connected to a counter 5, and the counter 5 can count the number of rotations of the screw. Through the above method, the lifting height and position of the gate 2 can be calculated, and since the lifting screw 3 is selected as the detection object, any method of driving the lifting screw 3 can be applied to this structure. Afterwards, the specific structure of the counter 5 is that the counter 5 includes a proximity switch 52 and a trigger member 54 that are relatively arranged, wherein the proximity switch 52 is located on one side of the lifting screw 3 and is fixed in position, and the trigger member 54 is relatively fixed to the lifting screw 3 and can rotate synchronously, and the proximity switch 52 counts the number of times the trigger member 54 passes the proximity switch 52, and the number of rotations of the lifting screw 3 can be calculated, and finally the height position of the gate 2 can be calculated.
[0030] In the above structure, taking the products purchased by our company as an example, the price of the photoelectric encoder with the specification of E6B2-CWZ6C is more than 60 yuan, while the price of the conventional magnetic proximity switch is only about 8 yuan. Even if the synchronization seat and trigger are included, the cost does not exceed 12 yuan. The cost can be said to be much lower, but at the same time, the required functions are still not affected. Therefore, the above method can reduce costs while maintaining the original functions, thereby improving the competitiveness of the product.
[0031] As shown in the above structure, different from the method of setting an encoder, the present device can record the number of rotations of the lifting screw 3 by setting a proximity switch 52, and thus can control the height position of the gate 2. Compared with the encoder, the price of the proximity switch 52 is lower, and the cost of the trigger member 54 is basically negligible. Therefore, it can effectively improve the competitiveness of the product, and it does not adopt a method of reducing product quality. The product quality is not changed and the function is normal.
[0032] In addition to the above structure, as another embodiment, in order to improve the monitoring accuracy, the trigger member 54 is arranged in multiple directions around the central axis of the lifting screw 3. If only one trigger member 54 is arranged, only the number of turns can be recorded, but if more trigger members 54 are arranged, the specific rotation angle of one turn of the lifting screw 3 can be controlled, and the accuracy is higher. And the intervals of the above trigger members 54 must be the same. Taking 4 trigger members 54 as an example, when the proximity switch 52 is triggered 4 times, it can prove that one turn has been made, and when there are 3 trigger signals, it can prove that the lifting screw 3 has rotated between 270°-360°. Since the lifting height of the gate plate 2 is limited when the lifting screw 3 rotates one turn, the above setting method is very reliable without the need for higher accuracy, and the lifting and lowering of the gate plate 2 can be ignored due to the small range of rotation.
[0033] At the same time, in order to ensure the accuracy of the recorded information, multiple proximity switches 52 are set along the rotation path of the trigger member 54. This avoids the failure of a single proximity switch 52, and can improve the accuracy and count the frequency division. Since the cost of the proximity switch 52 is not high, multiple proximity switches 52 can be selected. When multiple proximity switches 52 are used at the same time, the normal application of the equipment can be ensured after the failure of a single proximity switch 52, and the normal use of the equipment can be ensured during the inspection and maintenance.
[0034] It should be noted that in the above structure, in order to ensure that the triggering members 54 can trigger all the proximity switches 52 simultaneously, the number of the triggering members 54 is a positive integer multiple of the number of the proximity switches 52, and in the same period, all the proximity switches 52 can be aligned with the adjacent triggering members 54. Figure 3 , 4 As shown, in order to avoid the occurrence of asynchronous trigger signals of the proximity switches 52, the configuration of the proximity switches 52 needs to be determined based on the spacing of the trigger members 54 to ensure that the plurality of proximity switches 52 can generate trigger signals synchronously.
[0035] In the above structure, in order to facilitate the replacement of the proximity switch 52, the proximity switch 52 is fixed to the electric drive 4 through the reference plate 51 and can be disassembled, so as to facilitate rapid disassembly and replacement after a problem occurs.
[0036] like Figure 4 As shown, in order to facilitate the adjustment of the position of the proximity switch 52 according to the needs, the proximity switch 52 is fixed to the reference plate 51 through a waist-shaped hole, and the position can be adjusted. It is convenient to change the position according to the setting position of the trigger member 54 to ensure that the device can be used normally, and thus has a certain degree of applicability.
[0037] As an embodiment, the trigger member 54 is connected to the lifting screw rod 3 in such a manner that the lifting screw rod 3 is sleeved with a synchronous seat 53, and the trigger member 54 is arranged on the side of the synchronous seat 53 facing the proximity switch 52. It should be noted that in the above structure, the synchronous seat 53 is made of non-metallic material, and the trigger member 54 is made of metal material. This prevents the synchronous seat 53 from affecting the use of the proximity switch 52.
[0038] And in order to adjust the position of the trigger member 54, the fixed position of the synchronous seat 53 relative to the lifting screw 3 can be adjusted. Adjusting the synchronous seat 53 can adjust all the trigger members 54 at the same time to avoid the occurrence of a single trigger member 54 position misalignment.
[0039] Finally, in addition to the above structure, in order to facilitate installation and use, all trigger members 54 are located on the same horizontal plane, and all proximity switches 52 are located on the same horizontal plane.
