[0013] The present invention is not limited by the following embodiments, and specific implementation methods can be determined based on the technical solution of the present invention and actual conditions.

[0014] In this utility model, for the convenience of description, the relative position relationship of each component is described based on the Figure 1 For example, the positional relationships of front, back, up, down, left, and right are determined according to the layout directions of the drawings in the specification.

[0015] The present invention will be further described below in conjunction with the embodiments and accompanying drawings:

[0016] Example 1: As shown in the attached Figure 1 、 2 As shown, the bottom spacer in the water hole blasting hole includes an isolation tube, a tray 1, a measuring rope 2 and a plumb bob 3. The tray 1 is detachably fixedly installed on the upper end of the isolation tube. The outer side of the upper part of the tray 1 can be in sealing contact with the inner wall of the blast hole 7. The inner side of the lower end of the isolation tube is provided with a conical plumb bob 3 with a larger upper part and a smaller lower part. A measuring rope 2 is fixedly connected between the upper end of the plumb bob 3 and the lower end of the tray 1. A scale marking layer 4 is provided on the outer side of the measuring rope 2 for measuring the water depth in the blast hole 7. During use, the outer side of the tray 1 is in sealed contact with the inner wall of the blasthole 7, which can separate the water in the blasthole 7 and prevent the water in the blasthole 7 from mixing with the explosives and making the explosives ineffective. The outer side of the measuring rope 2 is provided with a scale marking layer 4 that can measure the water depth in the blasthole 7. When in use, the measuring rope 2 can be directly placed into the blasthole 7 to measure the water depth in the blasthole 7. The operation is simple, convenient and practical. The plumb bob 3 can prevent the measuring rope 2 from being entangled in the blasthole 7, so that the measuring rope 2 can measure accurately. When used in mine blasting, it can reduce the amount of charge, reduce costs, reduce roots and bulk, and improve the blasting effect.

[0017] The bottom spacer in the water hole blasting hole can be further optimized and / or improved according to actual needs:

[0018] Example 2: As an optimization of the above example, as shown in the attached Figure 1As shown, a sealing layer 5 is fixed to the outer portion of the upper portion of the tray 1. If required, the sealing layer 5 can be integrated with the tray 1. During use, the sealing layer 5 provides ductility. When filling the blasthole 7 with explosives, the tray 1 will tightly adhere to the hole wall due to compression, forming an effective barrier to prevent the explosives from contacting the water in the blasthole 7, which would render the explosives ineffective.

[0019] Example 3: As an optimization of the above embodiment, as shown in the attached Figure 1 、 2 As shown, the tray 1 is in the shape of a truncated cone with a larger top and a smaller bottom. A connecting screw hole is provided at the center of the lower end of the tray 1, and the outer side of the upper end of the isolation tube is screwed into the connecting screw hole. During use, the tray 1 is in the shape of a truncated cone with a larger top and a smaller bottom. In this way, the tray 1 can seal the inner walls of blastholes 7 of various specifications, expanding its application range. The outer side of the upper end of the isolation tube is screwed into the connecting screw hole, facilitating the assembly and disassembly of the isolation tube and the tray 1.

[0020] Example 4: As an optimization of the above embodiment, as shown in the attached Figure 1 As shown, the isolation tube comprises several connecting tubes 6, screwed together in sequence from bottom to top. The outer end of the uppermost connecting tube 6 is screwed into the connecting hole. If required, the connecting tubes 6 can be made of PVC to reduce the manufacturing cost of the isolation tube, thereby reducing blasting costs. For each pair of adjacent connecting tubes 6, the upper end of the lower connecting tube 6 is screwed together with the lower end of the upper connecting tube 6. This arrangement allows for quick assembly and disassembly during use, facilitating portability and transportation of the isolation tube.

[0021] The above technical features constitute the embodiments of the present invention, which have strong adaptability and implementation effect. Non-essential technical features can be added or removed according to actual needs to meet the requirements of different situations.
