[0034] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0035] In order to solve the problems of inaccurate measurement results, great difficulty in measurement and high cost in the prior art when determining whether the concrete poured in the foundation pit exceeds the line, the present utility model provides a preferred embodiment, such as Figure 1-Figure 2 As shown, an overfilling detector includes a detector body 1, a detection probe 2, an aviation plug 3 and a disc bracket 4.

[0036] The aviation plug 3 is located at the top of the detector body 1 and is used to power the detector. Specifically, the aviation plug 3 is electrically connected to an external power source. Specifically, the aviation plug 3 is electrically connected to the external power source via a cable.

[0037] The detection probe 2 is provided at the bottom end of the detector body 1 and is used to be inserted into the poured concrete in the foundation pit. The disc bracket 4 is sleeved on the detector body 1 and is located above the detection probe 2. When the overfilling detector is lowered into place, the disc bracket 4 contacts the horizontal surface of the concrete poured in the foundation pit, which can ensure that the overfilling detector is stably located in the foundation pit. In addition, since there is generally slurry or scum on the upper layer of the concrete poured in the foundation pit, when the overfilling detector is lowered into place, the gravity of the detection probe 2 is greater than or equal to the buoyancy of the disc bracket 4, so as to ensure that the disc bracket 4 is in close contact with the horizontal surface of the concrete poured in the foundation pit.

[0038] When detecting whether the concrete poured in the foundation pit exceeds the line, this embodiment lowers the overfilling detector into the foundation pit, and when the overfilling detector is lowered into place, the disc bracket 4 on the detector body 1 contacts the horizontal surface of the concrete poured in the foundation pit (that is, the top surface formed by the concrete poured in the foundation pit), and the lowering of the overfilling detector is stopped. At this time, the lowering height of the overfilling detector is recorded, and then combined with the depth of the foundation pit, it can be known whether the concrete poured in the foundation pit exceeds the line. The overfilling detector provided by the utility model has a simple structure and is easy to operate. It does not require manual marking, and solves the problems of the existing manual measurement of whether the concrete poured in the foundation pit exceeds the line, such as high difficulty and high cost. At the same time, the utility model does not require manual measurement during measurement, which relatively improves the accuracy of the measurement results.

[0039] In addition, when lowering the overfilling detector into the foundation pit, it can be achieved with the help of an external pay-out device. Specifically, the overfilling detector can be connected to the external pay-out device through a cable, and the cable is paid out by paying out the cable to lower the overfilling detector into the foundation pit. When the overfilling detector is lowered into place, the pay-out length of the pay-out device, that is, the lowering height of the overfilling detector, is recorded in time, and combined with the depth of the foundation pit to determine whether the concrete poured in the foundation pit exceeds the line. The pay-out device can be implemented by using a common pay-out wheel, etc., and will not be described in detail in this embodiment.

The main control board 11 is fixed to the main control board bracket 13, which supports and fixes the main control board 11, preventing it from moving during the vibration of the vibration motor 12. Similarly, the vibration motor 12 is located in the groove in the middle of the circular motor fixing block 14, thereby limiting the position of the vibration motor 12 and preventing it from moving due to vibration.

[0061] Preferably, a vibration sensor is also provided on the detection probe 2. The vibration sensor is electrically connected to the main control module and is used to detect the vibration intensity of the detection probe 2 on the detector body 1. The main control module also uploads the monitoring data of the vibration sensor to the host computer to determine the position of the detection probe 2 based on the vibration intensity of the detection probe 2. Normally, since there will be laitance and scum on the upper layer of concrete in the foundation pit, which do not belong to the actual poured concrete, the detection probe 2 will pass through laitance, scum and concrete in sequence during the lowering process. Then, under the drive of the same vibration motor 12, the vibration intensity of the detection probe 2 will be different. Therefore, after the main control module uploads the monitoring data of the vibration sensor to the host computer, the host computer will determine the position of the detection probe 2 based on the vibration intensity of the detection probe 2, which will help to assist in the judgment of the over-filling detector. For example, when the upper computer determines through the pay-out device that the over-filling detector has paid out the line in place, and according to the vibration intensity obtained by the vibration sensor, it is determined that the detection probe 2 is actually located in the scum layer, it means that the over-filling detector has not paid out the line in place and there is an error. If at this time it is judged whether the over-filling detector is over the line based on the pay-out length, the judgment result is wrong. Therefore, this embodiment determines the position of the detection probe 2 by setting a vibration sensor, and then assists in judging whether the over-filling detector has paid out the line in place.

[0062] More preferably, the aviation plug 3 includes a male aviation plug 31 and a female aviation plug 32; the male aviation plug 31 is fixedly connected to the top of the detector body 1; the female aviation plug 32 is mated and connected to the male aviation plug 31; and the female aviation plug 32 is electrically connected to the external power supply. Specifically, a sealing component is provided between the male aviation plug 31 and the detector body 1. The sealing component is preferably an O-ring.

[0063] Preferably, the detector body 1 is a float rod, and the density of the float rod is greater than the density of the scum on the horizontal surface of the concrete in the poured foundation pit. Specifically, by making the float rod's density greater than the scum, the detector probe 2 can be prevented from being inserted into the concrete due to buoyancy when it contacts the scum layer, thereby preventing the disc bracket 4 from contacting the horizontal surface of the concrete.

[0064] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
