Description

Technical Field

[0001] This application relates to the technical field of underground water temperature measurement, and in particular to an underground water temperature measurement device. Background Art

[0002] Underground water resources are one of the important fresh water resources on the earth and play a crucial role in human society and the ecological environment. In order to rationally develop and utilize underground water resources, it is necessary to do a good job in the investigation and evaluation of underground water resources and timely and accurately master the status of underground water resources.

[0003] Underground water temperature measurement is a part of the investigation and evaluation work of underground water conditions, which helps to comprehensively evaluate underground water conditions and provide a scientific basis for the protection and rational utilization of underground water, including hydrogeological characteristic analysis, pollution source identification, underground water quality assessment, ecological impact assessment, underground water utilization planning, and underground water model establishment. According to the requirements of the "Groundwater Monitoring Specification" (SL 183-2005), when monitoring water temperature, a water thermometer (or other temperature measuring equipment) needs to be placed at a position about 1 m below the water surface and left still for 5 min to obtain a stable water temperature reading.

[0004] The Chinese utility model patent with the publication number CN205607552U discloses an underground water temperature measurement device. In this device, a thermometer and a water storage cup are connected to each other, and the probe of the thermometer extends into the water storage cup. When the device is in use, it is put into the water, and under the action of water pressure, the valve at the bottom of the water storage cup opens, and underground water enters the water storage cup. When it continues to sink, the water in the water storage cup will be discharged from the water outlet hole through the guide cap until it reaches a position 1 m below the water surface and is left still in the water for 5 min. At this time, the water storage cup is filled with water samples at a position 1 m below the water surface. Then the device is lifted out of the water surface. During the process, the hinge plate closes the valve, and the temperature value of the thermometer is read, thus completing the entire measurement process. However, due to the poor sealing performance at the valve and the existence of the water outlet hole on the water storage cup, during the upward lifting process of the water storage cup, the water sample in the water storage cup is likely to come into contact and exchange with the water outside the cup, resulting in the impurity of the water sample in the final water storage cup, that is, it is not completely the underground water at a position 1 m below the water surface, thereby affecting the accuracy of the final underground water temperature measurement. Utility Model Content

[0005] In order to improve the defects existing in the above-mentioned prior art, this application provides an underground water temperature measurement device.

[0006] An underground water temperature measurement device provided by this application adopts the following technical solutions:

[0007] An underground water temperature measuring device includes a water thermometer and a sampling cup. The water thermometer is connected to the sampling cup and the probe of the water thermometer extends into the sampling cup. It further includes a sinking rod and a control member. The sinking rod is connected to the sampling cup. The sampling cup is provided with a water inlet, and a blocking member is arranged in the water inlet. The control member is arranged on the sinking rod and is connected to the blocking member. The control member can both control the blocking member to leave the water inlet and control the blocking member to block the water inlet.

[0008] By adopting the above technical solution, when the underground water temperature measuring device is in use, the sampling cup is sunk to a depth of 1 m below the water surface with the help of the sinking rod. During the process, the blocking member blocks the water inlet in the water inlet. Then, the control member is used to control the blocking member to leave the water inlet, that is, to open the water inlet. It is left standing at a depth of 1 m in the water for 5 minutes. The sampling cup is filled with water samples at a depth of 1 m below the water surface. Then, the control member is used to control the blocking member to block the water inlet again. The sampling cup is lifted out of the water surface with the help of the sinking rod. Finally, the value of the water thermometer is read, and the measurement process of the water temperature at a depth of 1 m below the water surface is completed. And during the process of lifting the sampling cup out of the water surface after sampling the water sample, the sampling cup is completely in a sealed state under the action of the blocking member. Therefore, the water sample in the sampling cup will not come into contact and exchange with the water body outside the cup, so as to ensure the accuracy of the final underground water temperature measurement.

[0009] Optionally, the water inlet penetrates through the sampling cup along the diameter direction of the sampling cup, and a left hole and a right hole are respectively formed on the side wall of the sampling cup. The blocking member is arranged in the water inlet and can block the water inlet. Under the control of the control member, the blocking member can move along the diameter direction of the sampling cup to control the blocking member to leave the water inlet and control the blocking member to block the water inlet.

[0010] By adopting the above technical solution, the control member can flexibly control the blocking member to move in the diameter direction of the sampling cup, so as to control the blocking member to open the water inlet or block the water inlet.

[0011] Optionally, the blocking member is made of rubber and is divided into a cylindrical part and a frustum part. The cylindrical part is arranged in the water inlet and can block the left hole and the right hole. The frustum part is arranged on the side of the cylindrical part close to the left hole. The control member can control the blocking member to move towards the right hole so that the cylindrical part leaves the left hole and the frustum part enters the left hole to open the water inlet. The control member can also control the blocking member to move towards the left hole so that the cylindrical part enters the left hole and the frustum part leaves the left hole to block the water inlet.

[0012] By adopting the above technical solution, actually, the cylindrical part of the plugging member functions to plug and seal the water inlet. The plugging member always plugs the right hole in the right hole, and under the action of the control member, the plugging member moves left and right to plug or leave the left hole, achieving the purpose of plugging or opening the left hole. The frustum part of the plugging member is used in cooperation with the cylindrical part. When the frustum part enters the left hole, the left hole is in an open state, that is, the water inlet is in an open state.

[0013] Optionally, the control member includes a left rope connected to the frustum part and a right rope connected to the cylindrical part. The left rope is connected to the center of the end face of the frustum part, and the right rope is connected to the center of the end face of the cylindrical part. The ends of the left rope and the right rope far from the plugging member are both connected to the end of the sinking rod far from the sampling cup.

[0014] By adopting the above technical solution, pulling the left rope and the right rope respectively can flexibly control the movement of the plugging member in the diameter direction of the sampling cup, so as to achieve the purpose of controlling the plugging member to open or block the water inlet.

[0015] Optionally, rings are connected to the ends of the left rope and the right rope far from the plugging member. A connection hole is provided at the end of the sinking rod far from the sampling cup. A fastener is also included. The rings at one end of the left rope and the rings at one end of the right rope are both sleeved on the fastener, and the fastener is threadedly connected to the connection hole.

[0016] By adopting the above technical solution, the fastener and the rings on the left rope and the right rope play a role in connecting the ends of the left rope and the right rope far from the plugging member to the sinking rod.

[0017] Optionally, two hollow pipe fittings are provided on the rod wall of the sinking rod. The hollow pipe fittings are arranged along the length direction of the sinking rod. The left rope passes through one of the hollow pipe fittings, and the right rope passes through the other hollow pipe fitting. Two knots are provided on each of the left rope and the right rope, and the two knots on the left rope are distributed at both ends of the corresponding hollow pipe fitting, and the two knots on the right rope are distributed at both ends of the corresponding hollow pipe fitting. The distance between the two knots on the left rope and the distance between the two knots on the right rope are both greater than the length of the hollow pipe fitting.

[0018] By adopting the above technical solution, the hollow pipe fittings and the knots function to limit the lifting range / amplitude of the left rope and the right rope, thereby controlling the displacement of the plugging member in the diameter direction of the sampling cup to meet the requirement of just opening or closing the water inlet, and avoiding the left rope and the right rope completely pulling the plugging member out of the water inlet and affecting the normal measurement and use of the underground water temperature measuring device.

[0019] Optionally, a cup holder is provided on the outer wall of the sampling cup, and the extended part of the cup holder is connected to one end of the sinking rod close to the sampling cup.

[0020] By adopting the above technical solution, the purpose of setting the cup holder is to connect and fix the sinking rod and the sampling cup.

[0021] Optionally, a marking buoy is provided on the sinking rod at a position 1 m away from the sampling cup.

[0022] By adopting the above technical solution, a marking buoy is provided on the sinking rod at a position 1 m away from the sampling cup, which helps the sampling cup to accurately sink to a depth of 1 m below the water surface.

[0023] In summary, the present application includes the following beneficial technical effects:

[0024] 1. When the underground water temperature measuring device of the present application is in use, the sampling cup is sunk to a depth of 1 m below the water surface with the help of the sinking rod. During the process, the sealing member seals the water inlet in the water inlet, and then the control member controls the sealing member to leave the water inlet, that is, the water inlet is opened. It is left standing in the water at a depth of 1 m for 5 minutes. The sampling cup is filled with water samples at a depth of 1 m below the water surface. Then, the control member controls the sealing member to block the water inlet again, and the sampling cup is lifted out of the water surface with the help of the sinking rod. Finally, the value of the thermometer is read, and the measurement process of the water temperature at a depth of 1 m below the water surface is completed. However, during the process of lifting the sampling cup out of the water surface after sampling the water sample at a depth of 1 m below the water surface, the sampling cup is completely in a sealed state under the action of the sealing member. Therefore, the water sample in the sampling cup will not come into contact and exchange with the water outside the cup, thus ensuring the accuracy of the final underground water temperature measurement.

Detailed Embodiments

[0029] The following is combined with the attached Figures 1-3A further detailed description of the present application is provided.

[0030] An embodiment of the present application discloses an underground water temperature measuring device. Referring to Figures 1-2 , the underground water temperature measuring device includes a sinking rod 3, a sampling cup 2, a thermometer 1, a sealing member 5 and a control member 4. The sinking rod 3 is a rod with a length greater than 1 m. The sampling cup 2 is a cylindrical cup body with a cup cavity inside. A cup holder 10 is provided on the outer wall of the sampling cup 2. The cup holder 10 is a plastic part and is semi-covered on the outer wall of the sampling cup 2 and bonded and fixed to the sampling cup 2. The cup holder 10 is integrally provided with a convex part and the convex part has a fixing hole for connecting the sinking rod 3. The thermometer 1 is connected to the sampling cup 2. Specifically, a through hole is opened at the exact center of the top wall of the sampling cup 2. The thermometer 1 passes through the through hole and the probe of the thermometer 1 extends into the sampling cup 2, so that the thermometer 1 can measure the water temperature of the water sample in the sampling cup 2. And a sealing member 12 is provided at the through hole. The sealing member 12 is a silica gel ring sleeved on the outer wall of the thermometer 1. The silica gel ring is tightly fixed on the outer wall of the thermometer 1 by its own elasticity. A ring groove is opened on the outer ring of the silica gel ring. The silica gel ring can be tightly clamped and fixed at the through hole by relying on the ring groove. In this way, both the thermometer 1 and the sampling cup 2 are fixed and the through hole is sealed, avoiding the contact and exchange of the water bodies inside and outside the sampling cup 2 after the sampling cup 2 samples the water sample at 1 m below the water surface.

[0031] Referring to Figure 2 , the sampling cup 2 has a water inlet 200. The water inlet 200 is opened through in the diameter direction of the sampling cup 2 and forms a left hole and a right hole on the side wall of the sampling cup 2 respectively. The sealing member 5 is arranged in the water inlet 200 and can block the water inlet 200 (block the left hole and the right hole at the same time). Specifically, the sealing member 5 is made of rubber and the sealing member 5 is divided into a cylindrical part 500 and a frustum part 501 which are of an integral structure. When the cylindrical part 500 blocks the left hole and the right hole at the same time in the diameter direction of the sampling cup 2, that is, the water inlet 200 is completely blocked, the water outside the cup cannot enter the sampling cup 2. The frustum part 501 is arranged on the side of the cylindrical part 500 close to the left hole. The frustum part 501 is a component used in cooperation with the cylindrical part 500. The control member 4 can control the movement of the sealing member 5 in the diameter direction of the sampling cup 2. That is, when the sinking rod 3 sinks the sampling cup 2 to 1 m below the water surface, the control member 4 controls the sealing member 5 to move towards the right hole. At this time, the cylindrical part 500 leaves the left hole and the frustum part 501 enters the left hole, and the left hole is in an open state, that is, the water inlet 200 is in an open state. It is left standing in the water at 1 m for 5 min. During this process, the groundwater at 1 m below the water surface enters the sampling cup 2 from the left hole, so that the sampling cup 2 is filled with the water sample at 1 m below the water surface. Then the control member 4 controls the sealing member 5 to move towards the left hole, so that the cylindrical part 500 enters the left hole and the frustum part 501 leaves the left hole to block the left hole, that is, block the water inlet 200.

[0032] It should be noted here that under the action of the control member 4, the blocking member 5 moves towards the left hole or the right hole. During the process, the cylindrical portion 500 always blocks the right hole in the right hole. The cylindrical portion 500 only moves left and right, plugs the left hole or leaves the left hole, so as to achieve the purpose of blocking or opening the left hole.

[0033] Refer to Figures 2-3 , the control member 4 includes a left rope 400 and a right rope 401. The left rope 400 is fixedly connected to the center of the end face of the frustum portion 501, and the right rope 401 is fixedly connected to the center of the end face of the cylindrical portion 500. The user can pull the left rope 400 to control the movement of the blocking member 5 towards the left hole, or pull the right rope 401 to control the movement of the blocking member 5 towards the right hole, so as to achieve the purpose of controlling the blocking member 5 to open or block the water inlet 200. Preferably, a ring 6 can be connected to each end of the left rope 400 and the right rope 401 away from the blocking member 5. A fastener 7 is provided at the end of the sinking rod 3 away from the sampling cup 2. The fastener 7 can be a bolt. A connection hole is provided on the outer wall of the sinking rod 3. After the rings 6 on the left rope 400 and the right rope 401 are sleeved on the bolt, the bolt is arranged in the connection hole and threadedly connected to the connection hole, so as to achieve the effect of fixing the ends of the left rope 400 and the right rope 401 away from the blocking member 5. The left rope 400 and the right rope 401 are used as the control member 4, which is relatively simple. Just pull them respectively to remotely control the blocking member 5 to realize the blocking and opening of the water inlet 200.

[0034] It should also be emphasized that two hollow pipe fittings 9 can be provided on the rod wall of the sinking rod 3. The length direction of the hollow pipe fittings 9 is the same as the length direction of the sinking rod 3. The left rope 400 can be passed through one of the hollow pipe fittings 9 and the right rope 401 can be passed through the other hollow pipe fitting 9. Two knots 8 are respectively provided on the left rope 400 and the right rope 401. Among them, the two knots 8 on the left rope 400 are distributed at both ends of the corresponding hollow pipe fitting 9 and the distance between the two knots 8 is greater than the length of the hollow pipe fitting 9. The two knots 8 on the right rope 401 are also distributed at both ends of the corresponding hollow pipe fitting 9 and the distance between the two knots 8 is greater than the length of the hollow pipe fitting 9. Through the above settings, the purpose of restricting the pulling range of the left rope 400 and the right rope 401 can be achieved, so as to control the displacement of the blocking member 5 in the diameter direction of the sampling cup 2, so as to just open or close the water inlet 200, and avoid the left rope 400 and the right rope 401 completely pulling the blocking member 5 away from the water inlet 200 and affecting the normal measurement and use of the underground water temperature measuring device.

[0035] Refer to Figure 1, Preferably, a marking buoy 11 may be provided at a position 1 m away from the sampling cup 21 on the sinking rod 3. Once the marking buoy 11 touches the water surface during the process of the sinking rod 3 sinking into the groundwater, it means that the sampling cup 2 has been lowered to a position 1 m below the water surface, so that the groundwater 1 m below the water surface can be accurately sampled, thereby improving the accuracy of the subsequent underground water temperature measurement.

[0036] The implementation principle of an underground water temperature measuring device disclosed in an embodiment of the present application is as follows: When the underground water temperature measuring device of the present application is in use, the sampling cup 2 is lowered to a position 1 m below the water surface by means of the sinking rod 3. During this process, the sealing member 5 seals the water inlet 200 in the water inlet 200, and then the control member 4 is used to control the sealing member 5 to leave the water inlet 200, that is, the water inlet 200 is opened. It is left standing in the water at a depth of 1 m for 5 minutes. The sampling cup 2 is filled with the water sample at a depth of 1 m below the water surface. Then, the control member 4 is used to control the sealing member 5 to block the water inlet 200 again, and the sampling cup 2 is lifted out of the water surface by means of the sinking rod 3. Finally, the value of the thermometer 1 is read, and the measurement process of the water temperature 1 m below the water surface is completed. However, during the process of lifting the sampling cup 2 out of the water surface after sampling the water sample 1 m below the water surface, the sampling cup 2 is completely in a sealed state under the action of the sealing member 5. Therefore, the water sample in the sampling cup 2 will not come into contact and exchange with the water outside the cup, so that the accuracy of the final underground water temperature measurement can be ensured.

[0037] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
