Description

Technical Field

[0001] This utility model relates to the field of ice flow monitoring technology, specifically an anti-freezing and anti-blocking device for ice flow monitoring. Background Technology

[0002] Flow measurement involves measuring and analyzing the dynamic elements of water bodies, such as flow rate and velocity. This system uses sensors to achieve "one-click flow measurement," collecting data on water level, flow velocity, topography, and water quality. During operation, the system can monitor specific points along the river channel.

[0003] From November to March of the following year, rivers in northern China freeze over. In the freezing conditions, hydrologists have to manually break through the ice to measure flow rates. This method is not only extremely labor-intensive and inefficient, but it also cannot achieve continuous observation at fixed points, resulting in the formation of "islands" of valuable hydrological data during the freezing period, making it difficult to systematically grasp the dynamic changes of rivers. Utility Model Content

[0004] The purpose of this invention is to provide an anti-freezing and anti-blocking device for flow monitoring under ice, which aims to solve the problem that existing technologies require drilling holes for each flow measurement, resulting in low efficiency and high labor intensity for workers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: the anti-freezing device for monitoring flow under ice includes an anti-freezing component installed on the ice surface and extending in the vertical direction, and a stabilizing component detachably connected to the anti-freezing component, so that the stabilizing component can keep the anti-freezing component installed vertically on the ice surface. The stabilizing component includes two symmetrically arranged clamps and four sets of gripping components arranged in a circumferential array around the clamps. The two clamps are fixedly connected to each other by bolts, and each clamp is hinged to the two sets of gripping components. One of the clamps is equipped with a level at its upper end.

[0006] Preferably, each of the clamps includes an outer clamp and an inner clamp, wherein the inner clamp is detachably connected to the outer clamp; The level is mounted on the outer clamp.

[0007] Preferably, the inner wall of the outer clamp is fixed with a plurality of circumferentially arranged outer protrusions, and the outer wall of the inner clamp is provided with a plurality of circumferentially arranged inner slots, and the outer protrusions are correspondingly inserted into the inner slots.

[0008] Preferably, a plurality of circumferentially arranged inner protrusions are fixed on the inner sidewall of the inner clamp, and a plurality of circumferentially arranged positioning grooves are provided on the outer sidewall of the antifreeze blockage component. The inner protrusions are correspondingly inserted into the positioning grooves so that the clamp and the antifreeze blockage component are positioned and installed.

[0009] Preferably, each of the gripping components includes a sleeve, an extension, and a hook; The end of the sleeve near the antifreeze plugging component is hinged to the outer clamp. The bottom of the sleeve has a guide groove with an opening facing downward and extending to the end of the sleeve near the antifreeze plugging component. The extension is guided and inserted into the guide groove. The end of the extension member away from the sleeve is fixedly connected to the hook claw; The extension and the sleeve are fixedly connected relative to each other by a locking assembly.

[0010] Preferably, the locking assembly includes a plurality of spaced through holes, an upward-facing bolt groove, and a positioning bolt; The through hole is formed on the sleeve, and the bolt groove is formed on the extension. The bolt groove is adapted to the through hole and the bolt groove.

[0011] Preferably, the antifreeze blockage assembly includes an outer cylinder, an inner cylinder, a conical plate, a spherical block, and a heating rod; The positioning groove is formed on the outer side of the outer cylinder, and an aerogel insulation layer is filled between the outer cylinder and the inner cylinder. The outer and inner cylinders are inserted into ice holes on the ice surface, with the bottoms of the outer and inner cylinders in contact with the river water. The heating rod is installed inside the inner cylinder; The conical plate is detachably mounted on the outer cylinder, and the spherical block is fixed on the conical plate.

[0012] Preferably, the ball block has a cavity inside, a positioning module is installed inside the cavity, and the surface of the ball block is coated with a highly reflective coating.

[0013] The beneficial effects are: 1. By adding an anti-freezing component, when ice-covered flow measurement is required, the operator can first activate the heating rod to melt the frozen portion between the outer cylinder and the ice surface, thus easily removing the anti-freezing component from the ice hole. Afterward, the sensor can smoothly measure the water flow under the ice. After the measurement is completed, the anti-freezing component is reinstalled on the ice hole for the next flow measurement. This design avoids the cumbersome process of re-drilling the ice hole for each measurement, effectively reducing the workload of operators and significantly improving the efficiency of ice-covered flow measurement.

[0014] 2. The stabilizing component is installed on top of the anti-freeze blockage component. Its core function is to ensure that the anti-freeze blockage component remains perpendicular to the ice surface during installation. This design effectively eliminates the risk of component tilting, thereby avoiding problems such as uneven heating of the heating rod and difficulty in disassembly caused by tilting. It also significantly reduces the wear and tear on the component itself and extends its service life. Attached Figure Description

[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0018] An anti-freezing device for monitoring flow under ice includes an anti-freezing component 1 installed on an ice surface 11 and extending in the vertical direction, and a stabilizing component detachably connected to the anti-freezing component 1. The stabilizing component is mainly used to assist in the installation of the anti-freezing component 1, so that the stabilizing component can install the anti-freezing component 1 on the ice surface 11 in a vertical state.

[0019] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in this embodiment, the stabilizing component includes two symmetrically arranged clamps 2 and four sets of gripping components 3 arranged in a circular array around the clamps 2. The two clamps 2 are fixedly connected by bolts. After the two clamps 2 are assembled, their interiors are circular. Each clamp 2 is hinged to two sets of gripping components 3, so that after the clamps 2 are installed, the gripping components 3 can be flipped and the end of the gripping component 3 away from the clamp 2 can be inserted into the ice surface 11, thereby improving the stability of the antifreeze blockage component 1.

[0020] Specifically, each clamp 2 includes an outer clamp 201 and an inner clamp 202. The inner clamp 202 is detachably connected to the inside of the outer clamp 201 to adjust the inner diameter of the clamp 2 according to the outer diameter of the antifreeze blockage component 1.

[0021] The inner wall of the outer clamp 201 is fixed with a number of external protrusions 5 arranged in a circular array, and the outer wall of the inner clamp 202 is provided with a number of internal slots 6 arranged in a circular array. The external protrusions 5 are inserted into the internal slots 6 to realize the installation and positioning of the outer clamp 201 and the inner clamp 202.

[0022] Several inner protrusions 7 arranged in a circular array are fixed on the inner side wall of the inner clamp 202. Several positioning grooves 8 arranged in a circular array are opened on the outer side wall of the antifreeze blockage component 1. The inner protrusions 7 are inserted into the positioning grooves 8 respectively. When the inner protrusions 7 and the positioning grooves 8 are matched, the clamp 2 and the antifreeze blockage component 1 can be positioned and installed.

[0023] Each gripping component 3 includes a sleeve 301, an extension 302, and a hook 303. In this embodiment, the hook 303 can hook onto the ice surface 11 to improve the support stability of the clamp 2. The end of the sleeve 301 near the antifreeze plugging component 1 is hinged to the outer clamp 201. The bottom of the sleeve 301 has a guide groove 9 with an opening facing downward and extending to the end of the sleeve 301 near the antifreeze plugging component 1. The extension 302 is guided and inserted into the guide groove 9. The end of the extension 302 away from the sleeve 301 is fixedly connected to the hook 303. The extension 302 and the sleeve 301 are relatively fixedly connected by the locking component 10. When a larger range of auxiliary installation foundation is required, the locking component 10 can be released first, and then the extension 302 can be moved along the guide groove 9. After the movement distance is appropriate, the locking component 10 can be locked.

[0024] like Figure 1 , Figure 2 , Figure 5 As shown, the locking assembly 10 enables a relatively fixed connection between the sleeve 301 and the extension 302.

[0025] Specifically, the locking assembly 10 includes several spaced through holes 1001, an upward-facing bolt groove, and a positioning bolt 1003. The through holes 1001 are formed on the sleeve 301, and the bolt groove is formed on the extension 302. When the bolt groove is adapted to the through holes 1001, the positioning bolt 1003 can pass through the through holes 1001 and be threadedly connected to the bolt groove, so that the extension 302 and the sleeve 301 are relatively fixedly connected.

[0026] In this embodiment, a stop bar 12 is bolted to the outer side of the outer clamp 201. When the sleeve 301 is rotated to be perpendicular to the outer clamp 201, the stop bar 12 can be installed on the outer clamp 201, so that the clamping component 3 can support the antifreeze blockage component 1.

[0027] like Figure 1 , Figure 2 As shown, a level 4 is installed on the upper end of one of the clamps 2 to monitor whether the clamp 2 installed on the antifreeze blockage assembly 1 is vertical. If it is not vertical, the rotation angle of the sleeve 301 needs to be adjusted. The level 4 is installed on the outer clamp 201.

[0028] In this embodiment, the level 4 is a bubble level. The structure and principle of the bubble level are existing technologies and will not be described in detail here.

[0029] A 250mm diameter, 1.2m deep ice hole is created by manually or mechanically chiseling away ice fragments. Figure 3 As shown, the anti-freeze assembly 1 is placed into the ice hole, and the coaxiality is adjusted. The anti-freeze assembly 1 is then immersed in the water beneath the ice. In the low-temperature environment, the anti-freeze assembly 1 freezes together with the inner wall of the ice hole. When clearing the ice hole, a heating rod is used to heat the hole, causing the anti-freeze assembly 1 to melt and detach from the inner wall of the ice hole. The anti-freeze assembly 1 can then be easily removed from the ice hole. The ice fragments in the ice hole are then cleaned to facilitate flow measurement. Specifically, the anti-freeze blockage component 1 includes an outer cylinder 101, an inner cylinder 102, a conical plate 103, a spherical block 104, and a heating rod 105. In this embodiment, a battery is installed inside the spherical block 104, which can power the positioning module and the heating rod 105. This structure and principle are existing technologies and will not be described in detail here. The positioning groove 8 is formed on the outer side of the outer cylinder 101, so that the clamp 2 is installed on the outer side of the outer cylinder 101. An aerogel insulation layer is filled between the outer cylinder 101 and the inner cylinder 102. In this embodiment, the structure and principle of the aerogel insulation layer are existing technologies and will not be described in detail here. The outer cylinder 101 and the inner cylinder 102 are inserted into the ice holes on the ice surface 11, and the bottoms of the outer cylinder 101 and the inner cylinder 102 are in contact with the river water. The heating rod 105 is installed inside the inner cylinder 102. Heating the heating rod 105 can melt the bonding between the outer cylinder 101 and the ice hole, making it easier for the anti-freeze blocking component 1 to detach from the ice hole. After detachment, the sensor can be placed in the water in the ice hole to measure the flow. After the measurement is completed, the anti-freeze blocking component 1 is frozen in the ice hole and the ice hole is sealed again with the anti-freeze blocking component 1 for the next flow velocity measurement. The conical plate 103 is detachably installed on the outer cylinder 101, and the ball block 104 is fixed on the conical plate 103.

[0030] The ball block 104 has a cavity inside, and a positioning module is installed inside the cavity. In this embodiment, the structure and principle of the positioning module are existing technologies and will not be described in detail here, so as to transmit the position in real time. The surface of the ball block 104 is coated with a highly reflective coating for rapid identification.

[0031] Working principle: When using, first chisel an ice hole into the ice surface 11, ensuring the hole can contact the water surface. Then, install the antifreeze plugging component 1 inside the ice hole, ensuring the bottom of the antifreeze plugging component 1 can contact the water surface. During installation, install the clamp 2 on the outside of the antifreeze plugging component 1. Then, adjust the angle of the antifreeze plugging component 1 according to the level 4. After adjustment, flip the sleeve 301 to be parallel to the ice surface 11. Then, hook the claw 303 onto the ice surface 11. After hooking, insert the stop bar 12 into the outer clamp 201 to block the sleeve 301, making the installation of the antifreeze plugging component 1 more stable.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims and not by the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
