Description

Technical Field

[0001] The utility model relates to the technical field of irrigation area monitoring, in particular to a monitoring and early warning device applied to irrigation areas. Background Art

[0002] With the continuous development and progress of resource management technology, it is necessary to implement environmental testing in irrigation district water conservancy management areas in order to facilitate the management and maintenance of irrigation district water conservancy. Remote monitoring can make corresponding maintenance and solutions based on the data from environmental testing.

[0003] An intelligent and efficient monitoring device for ecological irrigation areas disclosed in Chinese patent CN216081671U monitors the water level of the irrigation area through a floating ring. The counterweight provides downward pulling force for the winding rope to keep the winding rope in a pulled-in state, so that the winding rope can be adaptively extended and retracted according to the change of the water surface. When the winding rope is extended and retracted, it can synchronously drive the moving slide to move. When the moving slide moves, it can synchronously drive the sliding member to move through the linkage rod. When the sliding member contacts the contact switch, the alarm is activated to remind the maintenance personnel that the water level change of the ecological irrigation area exceeds the safe range, so as to facilitate the maintenance personnel to monitor the irrigation area intelligently and efficiently. However, while solving the problem, the intelligent and efficient monitoring device for ecological irrigation areas has the following defects:

[0004] The reel is soft, so the float floats in the irrigation channel. The flow of water in the irrigation channel will give the float a pulling force, driving the float to move downstream. The faster the water flow rate, the greater the pulling force on the float, so that the reel is tilted. The inclination angle of the reel changes with the speed of the water flow. Therefore, the sliding part touches the electric switch, and the alarm is activated, and the accuracy of the warning result is poor. Utility Model Content

[0005] The purpose of the utility model is to solve at least one of the technical defects described in the background technology.

[0006] To this end, one purpose of the utility model is to propose a monitoring and early warning device for irrigation areas, aiming to solve the problem of poor accuracy of early warning results of intelligent and efficient monitoring equipment for ecological irrigation areas in the prior art.

[0007] In order to achieve the above-mentioned purpose, an embodiment of the utility model on one hand provides a monitoring and early warning device for irrigation areas, including a crossbeam, a conduit is fixedly connected to the bottom of one end of the crossbeam, a floating ring is slidably connected to the outer surface of the conduit, a top rod is arranged on the top of the floating ring, a contact switch is fixedly installed at a position corresponding to the top rod at the bottom of the crossbeam, and an alarm is fixedly installed on the top of the crossbeam.

[0008] Preferably, a hole groove is provided in the middle of the float ring, and the float ring is slidably connected to the outer surface of the conduit through the hole groove, a slider is fixedly connected to the inner wall of the hole groove, a vertical groove is provided on the outer surface of the conduit, and the slider is slidably connected in the vertical groove, the push rod is fixedly connected to the top of the slider, and the push rod is inserted into the inside of the conduit, and a notch that passes through the vertical groove is provided at the bottom end of the conduit, and a positioning block is fixedly connected to the outer surface of the top end of the push rod, the width of the notch is smaller than the width of the vertical groove, and the width of the positioning block is equal to the width of the vertical groove. When the water level of the irrigation channel is low, the push rod can extend from the conduit, so that the float ring continues to descend, thereby shortening the use length of the conduit, so that when the water level is high, the length of the conduit located in the water is shorter, which can reduce the possibility of the conduit being bent by the water flow.

[0009] Preferably, the bottom of the cross beam is fixedly connected to a limit block, and when the push rod touches the contact switch, the limit block supports the positioning block to prevent the water level from continuing to rise, so that the buoyancy of the float ring is applied to the contact switch and the contact switch is damaged.

[0010] Compared with the prior art, the advantages and beneficial effects of the utility model are:

[0011] 1. By setting up a conduit, the float is slidably connected to the outer surface of the conduit. The conduit is perpendicular to the water surface of the irrigation canal. When the water level in the irrigation canal rises or falls, the float rises or falls vertically, thereby driving the top rod to rise or fall vertically. When the water level is too high, the top rod rises and hits the contact switch, and the alarm is energized to issue an early warning. Since the conduit is not affected by the water flow rate and is always vertical, the result of the alarm starting the early warning is accurate.

[0012] 2. By slidingly connecting the top rod inside the conduit, the top rod and the conduit form a telescopic rod structure. Therefore, when the water level is low, the top rod will extend from the conduit, thereby reducing the usable length of the conduit. When the water level is high, the length of the conduit in the water is shorter, which can reduce the resistance of the conduit in the water flow, thereby reducing the possibility of the conduit being bent by the water flow and improving the reliability of the structure.

[0013] 3. By setting the limit block, when the top rod rises and hits the contact switch to energize the alarm, the limit block hits the positioning block, so that the limit block overcomes the buoyancy of the float ring and avoids the problem of contact switch being damaged by force.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] The utility model provides a monitoring and early warning device applied to irrigation areas.

[0024] Embodiment 1:

[0025] like Figure 1-4As shown, it includes a crossbeam 1, one end of the crossbeam 1 is fixedly connected to a flange 13, the crossbeam 1 is fixedly installed with a connecting block 4 through the flange 13, the bottom of the connecting block 4 is fixedly connected to a support rod 41, the support rod 41 supports the crossbeam 1 so that the crossbeam 1 can span over the irrigation canal, the bottom end of the support rod 41 is fixedly connected to a base 42, the bottom of one end of the crossbeam 1 is fixedly connected to a conduit 2, the outer surface of the conduit 2 is slidably connected with a float 3, a hole groove 31 is opened in the middle of the float 3, the float 3 is slidably connected to the outer surface of the conduit 2 through the hole groove 31, a top rod 33 is arranged on the top of the float 3, a contact switch 11 is fixedly installed at a position corresponding to the top rod 33 at the bottom of the crossbeam 1, and an alarm 12 is fixedly installed on the top of the crossbeam 1. As the water level of the irrigation canal rises, the float 3 slides upward along the conduit 2, and the top rod 33 rises with the float 3. When the float 3 rises to a certain height, the top rod 33 touches the contact switch 11, and the alarm 12 is energized, thereby playing a warning role.

[0026] Embodiment 2:

[0027] like Figure 2-4 As shown, on the basis of the first embodiment, the inner wall of the hole groove 31 is fixedly connected with a slider 32, the outer surface of the conduit 2 is provided with a vertical groove 21, the slider 32 is slidably connected in the vertical groove 21, the push rod 33 is fixedly connected to the top of the slider 32, and the push rod 33 is inserted into the inside of the conduit 2, and the bottom end of the conduit 2 is provided with a notch 22 that passes through the vertical groove 21, the slider 32 can slide from the inside of the conduit 2 to the bottom thereof through the notch 22, and the outer surface of the top end of the push rod 33 is fixedly connected with a positioning block 34, the width of the notch 22 is smaller than the width of the vertical groove 21, and the width of the positioning block 34 is equal to the width of the vertical groove 21, when the float 3 drops to a certain height, the positioning block 34 will be stuck above the notch 22, thereby avoiding the problem of the push rod 33 falling off from the conduit 2.

[0028] Further, such as Figure 2 As shown, the bottom of the cross beam 1 is fixedly connected with a limit block 14. When the top rod 33 rises and contacts the contact switch 11, the limit block 14 contacts the positioning block 34, so that the limit block 14 overcomes the buoyancy of the float 3, thereby avoiding the problem of the contact switch 11 being damaged by force.

[0029] The working principle of the utility model is as follows: when in use, the support rod 41 is fixed to the edge of the irrigation channel through the base 42, so that the crossbeam 1 spans above the irrigation channel, the guide tube 2 is perpendicular to the water surface, and the float 3 is located on the water surface in the irrigation channel to provide support for the top rod 33. As the water level rises and falls, the float 3 rises and falls, driving the top rod 33 to rise and fall. When the water level is too high, the top rod 33 rises and contacts the contact switch 11, and the alarm 12 is energized to issue an early warning, thereby achieving the purpose of monitoring and early warning.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1. By setting the conduit 2, the float 3 is slidably connected to the outer surface of the conduit 2. The conduit 2 is perpendicular to the water surface of the irrigation canal. When the water level in the irrigation canal rises and falls, the float 3 rises and falls vertically, thereby driving the top rod 33 to rise and fall vertically. When the water level is too high, the top rod 33 rises and contacts the contact switch 11, and the alarm 12 is powered on to issue an early warning. Since the conduit 2 is not affected by the water flow rate and is always vertical, the result of the alarm 12 starting the early warning is accurate.

[0032] 2. By slidingly connecting the top rod 33 inside the conduit 2, the top rod 33 and the conduit 2 form a telescopic rod structure. Therefore, when the water level is low, the top rod 33 will extend from the conduit 2, thereby reducing the usable length of the conduit 2. When the water level is high, the length of the conduit 2 in the water is shorter, which can reduce the resistance of the conduit 2 in the water flow, thereby reducing the possibility of the conduit 2 being bent by the water flow, thereby improving the reliability of the structure.

[0033] 3. By setting the limit block 14, when the top rod 33 rises and contacts the contact switch 11 to energize the alarm 12, the limit block 14 contacts the positioning block 34, so that the limit block 14 overcomes the buoyancy of the float 3, thereby avoiding the problem of the contact switch 11 being damaged by force.
