One end of the pressing plate extends into the trigger housing and is connected to the end of the elastic component close to the water level measuring device, and is provided with a second through hole for the connecting rope to pass through. The other end of the pressing plate extends out of the trigger housing.

[0008] Preferably, a buckle is provided on the outer wall of the striker housing. The buckle is located at the position of the maximum compression of the elastic component and is engaged with the end of the pressing plate extending out of the striker housing.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0023] The purpose of the present utility model is to provide a lake water level measuring device to solve the problems existing in the above-mentioned prior art. The water level measuring device is thrown into the lake to be measured by a trigger, and then the water level is measured, eliminating the need for fixed-point observation in the prior art and improving the convenience of water level measurement.

[0024] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] As Figures 1 to 2 shown, this embodiment provides a lake water level measuring device, including a water level measuring device 1, a connecting rope, and a trigger for throwing the water level measuring device 1; preferably, a water level pressure sensor is installed on the water level measuring device 1, and the water level measuring device 1 carries the water level pressure sensor and sinks to the bottom of the lake to be measured to measure the water level of the lake to be measured; and the water level measuring device 1 is made of a material with a density much greater than that of water, so that the water level measuring device 1 can quickly sink to the bottom of the lake. The safety rope 6 is preferably made of synthetic materials such as nylon, which has high flexibility and a diameter in the millimeter range, and can sufficiently reduce the action of the water flow resistance in the lake on it;

[0026] The trigger includes a trigger housing 2 for accommodating the water level measuring device 1. The trigger housing 2 is provided with a throwing port and a first through hole for the water level measuring device 1 to be thrown out and the connecting rope to pass through. The throwing port and the first through hole are located at both ends of the trigger housing 2 along the direction of the water level measuring device 1 being thrown out, and the structure of the first through hole is smaller than the radial cross-section of the water level measuring device 1;

[0027] A resetable elastic component 5 is compressed between the end of the water level measuring device 1 close to the first through hole and the first through hole. It should be noted that the restoring force of the elastic component 5 is large enough to be able to throw the water level measuring device 1 a sufficient distance to the required measurement point; a runner 7 is rotatably installed on the trigger housing 2 on the side of the first through hole away from the elastic component 5; one end of the connecting rope passes through the first through hole and is connected to the water level measuring device 1, and the other end is wound around the runner 7;

[0028] Before being thrown out, the water level measuring device 1 is located inside the trigger housing 2 and compresses the elastic component 5. After aligning the position, the elastic component 5 is released, and the elastic component 5 resets and elongates, ejecting the water level measuring device 1 and throwing it out from the throwing port. Since one end of the safety rope 6 is connected to the water level measuring device 1, the water level measuring device 1 carries one end of the safety rope 6 and moves synchronously after being thrown out. The other end of the safety rope 6 is wound around the runner 7. While the safety rope 6 continuously extends out of the throwing port, the runner 7 rotates to release the remaining safety rope 6 until the water level measuring device 1 sinks to the bottom of the lake to be measured, thus completing the measurement of the water level of the lake to be measured. Preferably, to prevent the safety rope 6 from detaching from the runner 7, the end of the safety rope 6 not connected to the water level measuring device 1 is fixed to the runner 7.

[0029] After the test is completed, by rotating the runner 7 and making it rotate in the reverse direction, the safety rope 6 is wound up, thereby dragging the water level measuring device 1 to recover, so as to perform re-measurement at the next measurement point. The use of the entire device does not require building a base station at a certain place in a lake or river to place a water level observation device for fixed-point measurement. When it is necessary to measure multiple points of the same lake or river, it can be conveniently moved to each required position and measured one by one. Especially when applied in desert areas, it can be carried by a single person, solving the technical problem that the desert area is large and it is inconvenient to carry large-scale equipment in the prior art to observe all lakes.

[0030] As a preferred embodiment of the present utility model, a pressing plate 4 is slidably installed on the firing device housing 2 along the direction in which the water level measuring device 1 is thrown. Among them, a slot extending along the axial direction of the firing device housing 2 is opened on the firing device housing 2, and the pressing plate 4 is slidably installed in the slot. One end of the pressing plate 4 extends into the firing device housing 2 and is connected to the end of the elastic component 5 close to the water level measuring device 1, and a second through hole for the connecting rope to pass through is opened. The other end of the pressing plate 4 extends out of the firing device housing 2, so that before use, by moving the end of the pressing plate 4 located on the firing device housing 2, the part of the pressing plate 4 located inside the firing device housing 2 presses the elastic component 5, so that the elastic component 5 is compressed to the maximum amount, and then the water level measuring device 1 is arranged at the pressing plate 4. Then during measurement, by releasing the pressing plate 4, the pressing plate 4 quickly returns under the action of the spring rebound force, thereby pushing the water level measuring device 1 to move and throwing it out of the throwing port of the firing device housing 2.

[0031] Furthermore, a buckle 3 is provided on the outer wall of the firing device housing 2. The buckle 3 is located at the position of the maximum compression amount of the elastic component 5 and is clamped with the end of the pressing plate 4 extending out of the firing device housing 2. Before the elastic component 5 returns and elongates, by clamping the pressing plate 4 at the buckle 3, the position of the pressing plate 4 is fixed to maintain the compression amount of the elastic component 5. And when the water level measuring device 1 is recovered, the pressing plate 4 can be clamped at the buckle 3 to vacate a space for accommodating the water level measuring device 1. During use, by separating the pressing plate 4 from the buckle 3, the elastic component 5 returns and elongates.

[0032] Preferably, the firing device housing 2 has a straight cylindrical structure, and the water level measuring device 1 has a straight rod-shaped structure matching the structure of the firing device housing 2. The throwing port and the second through hole are located at both ends of the firing device housing 2 along the axial direction. By optimizing the structures of the firing device housing 2 and the water level measuring device 1, the firing device housing 2 is used to guide the water level measuring device 1 to ensure the accuracy of the throwing direction of the water level measuring device 1. Among them, the end of the water level measuring device 1 away from the second through hole has a conical structure, and its structure gradually decreases along the throwing direction to reduce the air resistance received by the water level measuring device 1 and ensure the moving distance of the water level measuring device 1.

[0033] Among them, the elastic component 5 is a spring coaxially arranged with the water level detector 1, and the spring is coaxially wound around the outer peripheral side of the second through hole. By setting the spring and optimizing its installation position, it is ensured that an elastic force in the axial direction of the water level detector 1 is provided, so that the water level detector 1 can be effectively thrown out. The elastic component 5 can also be a multi-group spring structure, which is wound around the outer peripheral side of the second through hole at equal intervals along the axis and is connected to the pressing plate 4.

[0034] As a preferred embodiment of the present utility model, a driving motor 8 is installed on the firing device housing 2 on the side away from the elastic component 5 of the first through hole. The driving motor 8 is equipped with a power supply component for supplying power to it. The power supply component includes a power cord and a power source component. The power source component and the driving motor 8 are electrically connected through the power cord so that the output shaft of the driving motor 8 rotates. The power source component can be installed on the firing device housing 2, specifically, it can be a storage battery or a lithium battery, etc., or it can also be an external power source, etc. The driving motor 8 is powered through a power socket. The runner 7 is coaxially and detachably connected to the output shaft of the driving motor 8. By driving the runner 7 to rotate through the driving motor 8, the safety rope 6 is electrically wound up, saving manpower. Since the runner 7 is detachably connected to the output shaft of the driving motor 8, before the water level detector 1 is thrown out, the runner 7 is disassembled from the output shaft to ensure that the runner 7 can rotate quickly without being affected by the external forces of the rotor and stator of the driving motor 8. When the safety rope 6 needs to be recovered, the runner 7 is reinstalled on the output shaft of the driving motor 8. Preferably, the driving motor 8 is a micro motor, which can rotate the runner 7 while reducing its own weight for easy carrying.

[0035] Furthermore, the runner 7 is provided with a runner shaft and an outer ring portion coaxially wound around the outer peripheral side of the runner shaft. The connecting rope is wound on the outer ring portion. The runner shaft is rotatably installed on the firing device housing 2, and a coupling is detachably connected between the runner shaft and the output shaft of the driving motor 8 to realize the detachable connection between the runner shaft and the driving motor 8 through the coupling. Preferably, two bearing seats are rotatably connected to the runner shaft on both sides of the outer ring portion. The bearing seats are detachably connected to the firing device housing 2, and one end of the runner shaft extends out of the corresponding bearing seat and is connected to the output shaft of the driving motor 8 through a coupling. By setting the bearing seats, the entire runner 7 can be detachably installed on the firing device housing 2, and then, according to different lake conditions, such as depth and width, etc., the safety rope 6 with a corresponding length and its supporting runner 7 can be replaced.

[0036] Preferably, the firing device housing 2 is connected with a grip 9 extending in the same direction as it. The grip 9 is connected to the second through hole and is located on one side of the runner 7 and the driving motor 8. The entire firing device housing 2 is lifted manually through the grip 9 to avoid the outlet for throwing the water level detector being too low and being easily affected by the uneven ground on the lake shore.

[0037] Adaptability changes made according to actual requirements are within the protection scope of the present utility model.
