Description

TECHNICAL FIELD

[0001] The utility model relates to water level detection equipment technical field especially portable water level detector. BACKGROUND

[0002] The portable water level detector is a kind of portable equipment for measuring water level, it is usually used to monitor the water level change of river, lake, reservoir, water well, water tank, water treatment facility etc. The design of this instrument aims to facilitate users to measure water level at different places, and it is suitable for various occasions such as field work, environmental monitoring, agricultural irrigation, hydrological monitoring, disaster prevention and emergency response.

[0003] The existing portable water level detector, when in use, firstly removes the probe connecting line stored in the line group storage slot, pulls out the detection probe embedded in the probe embedding slot, inserts the other end of the probe connecting line into the probe connecting hole, puts the detection probe into water, controls the equipment to run through the control button, observes the detection data through the main display screen and the auxiliary display screen, and thus the water level detection can be realized. After use, the probe connecting line is wound into the line group storage slot, the detection probe is embedded into the probe embedding slot, and the part of the probe connecting line connected at one end can be embedded into the line head embedding slot. At this time, the carrying box cover is closed, the detector carrying box and the carrying box cover are locked through the box body lock and the lock head, and the detection equipment can be conveniently taken and carried as a whole through the box handle. When the carrying box cover is opened and rotated to a certain angle through the connecting hinge, the supporting iron ring can support the carrying box cover. In this way, it is more convenient to observe the display screen inside when in use, and it is not necessary to use other equipment to support the carrying box cover. However, the existing portable water level detector can effectively absorb vibration energy through the buffer foam embedded in the water level detector. When it is found that the parts inside the instrument are loose, displaced or emit abnormal sound during normal use, it is likely that the shock-absorbing capacity of the buffer foam has decreased, which means that it cannot protect the instrument well, and the foam needs to be replaced. However, the current buffer foam is embedded in the water level detector. When it needs to be replaced, the shell of the instrument may need to be disassembled, which usually involves removing multiple screws and unfastening the buckle. Disassembling the shell may damage the waterproof and dustproof performance of the instrument, increasing the risk of subsequent use.

[0004] Therefore, it is necessary to provide a new portable water level detector to solve the above technical problems. UTILITY MODEL CONTENTS

[0008] Preferably, the limiting assembly comprises a fixed plate and a limiting plate, the fixed plate is fixedly connected to the bottom of the connecting frame, and the limiting plate is fixedly connected to the side wall of the connecting frame.

[0009] Preferably, a limiting device is fixedly connected to the inner wall of each placing groove formed in the buffer foam, the limiting device comprises a fixed frame and two buffer springs, the fixed frame is fixedly connected to the inner wall of the placing groove, the two buffer springs are respectively fixedly connected to the inner wall of the fixed frame, a support plate is fixedly connected to the end of the two buffer springs away from the fixed frame, a hinged rod is rotationally connected to the end of the support plate away from the buffer spring through a placing frame, and an elastic plate is rotationally connected to the end of the hinged rod away from the buffer spring through a movable frame.

[0010] Preferably, the elastic piece is a compression spring, one end of the compression spring is fixedly connected to the inner wall of the connecting frame, and a fixed block is fixedly connected to the end of the compression spring away from the connecting frame.

[0013] Preferably, a storage groove for placing a wire group is formed in the buffer foam.

[0014] Compared with the related art, the portable water level detector has the following beneficial effects:

[0015] With the designed connecting device, when the cushioning foam needs to be replaced, the cushioning foam is first pressed, causing it to press against the bottom of the limiting frame and apply pressure to the fixing clamp. The fixing clamp then moves the fixing block, movable plate, and positioning rod downwards. The fixing block compresses the compression spring. At this time, under the action of the fixing plate and the limiting plate, the positioning rod causes the positioning block to slide out from one side of the limiting plate. Under the action of the compression spring, the positioning block moves the movable plate, fixing plate, limiting rod, and fixing frame upwards. The limiting plate, having lost the restriction of the groove on the top of the outer shell, loses its restriction on the limiting frame. Then, the cushioning foam can be removed, and the new or replacement cushioning foam can be taken out and installed. This device reduces the risk of damage to the instrument's waterproof and dustproof performance due to disassembly of the outer shell, thus reducing the risk of subsequent use.
